1. Description of the Company

Masimo Corporation (the Company) is a global medical technology company that develops, manufactures and markets a variety of noninvasive patient monitoring technologies. The Company’s mission is to improve patient outcomes and reduce cost of care by taking noninvasive monitoring to new sites and applications. The Company’s patient monitoring solutions generally incorporate a monitor or circuit board, proprietary single-patient use, reusable or resposable sensors, software and/or cables. The Company primarily sells its products to hospitals, emergency medical service (EMS) providers, home care providers, physician offices, veterinarians, long term care facilities and consumers through its direct sales force, distributors and original equipment manufacturer (OEM) partners.

The Company invented Masimo Signal Extraction Technology ^® (SET ^® ), which provides the capabilities of Measure-Through-Motion and Low-Perfusion ^™ pulse oximetry to address the primary limitations of conventional pulse oximetry. Over the years, the Company’s product offerings have expanded significantly to also include noninvasive optical blood constituent monitoring, optical organ oximetry monitoring, electrical brain function monitoring, acoustic respiration monitoring and optical gas monitoring. The Company also developed the Root ^® patient monitoring and connectivity platform and the Masimo Patient SafetyNet ^™ remote patient surveillance monitoring system. These solutions and related products are based upon Masimo SET ^® , rainbow ^® and other proprietary algorithms. These software-based technologies are incorporated into a variety of product platforms depending on customers’ specifications. This technology is supported by a substantial intellectual property portfolio that the Company has built through internal development and, to a lesser extent, acquisitions and license agreements.

2. Summary of Significant Accounting Policies

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). Certain information and note disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) have been condensed or omitted pursuant to such rules and regulations. The condensed consolidated financial statements have been prepared on the same basis as the annual financial statements and, in the opinion of management, reflect all adjustments, including normal recurring accruals, necessary to present fairly the Company’s condensed consolidated financial statements. The condensed consolidated balance sheet as of January 3, 2015 was derived from the Company’s audited consolidated financial statements at that date. The accompanying condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes contained in the Company’s Annual Report on Form 10-K for the fiscal year ended January 3, 2015 (fiscal year 2014), filed with the SEC on February 17, 2015 . The results for the three and nine months ended October 3, 2015 are not necessarily indicative of the results to be expected for the fiscal year ending January 2, 2016 (fiscal year 2015) or for any other interim period or for any future year.

Principles of Consolidation

The condensed consolidated financial statements include the accounts of the Company, its wholly-owned subsidiaries and the variable interest entity (VIE) of which the Company is the primary beneficiary. All intercompany balances and transactions have been eliminated in consolidation. In accordance with GAAP, current authoritative guidance is applied when determining whether an entity is subject to consolidation.

Fiscal Periods

The Company follows a conventional 52/53 week fiscal year. Under a conventional 52/53 fiscal year, a 52 week fiscal year includes four quarters of 13 fiscal weeks while a 53 week fiscal year includes three 13 fiscal week quarters and one 14 fiscal week quarter. The Company’s last 53 week fiscal year was fiscal year 2014. Fiscal year 2015 is a 52 week fiscal year. All references to years in these notes to condensed consolidated financial statements are fiscal years unless otherwise noted.

Use of Estimates

The Company prepares its financial statements in conformity with GAAP, which requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Significant estimates include the determination of accounts receivable allowances, inventory reserves, warranty reserves, rebate accruals, valuation of the Company’s stock options, goodwill valuation, deferred taxes and any associated valuation allowances, distributor channel inventory, royalty revenues, deferred revenue, uncertain income tax positions, litigation costs and related accruals. Actual results could differ from such estimates.

Reclassifications

Certain amounts in the condensed consolidated financial statements for prior periods have been reclassified to conform to the current period presentation.

Fair Value Measurements

Authoritative guidance describes a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value:


●	Level 1—Quoted prices in active markets for identical assets or liabilities.


●	Level 2—Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that can be corroborated by observable market data for substantially the full term of the assets or liabilities.


●	Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

Pursuant to current authoritative guidance, entities are allowed an irrevocable option to elect the fair value for the initial and subsequent measurement for specified financial assets and liabilities on a contract-by-contract basis. The Company did not elect the fair value option under this guidance as to specific assets or liabilities. There were no transfers between Level 1, Level 2 and Level 3 inputs during the three and nine months ended October 3, 2015 . The Company carries cash and cash equivalents at cost, which approximates fair value. As of October 3, 2015 and January 3, 2015 , the Company did not have any short-term investments.

The following tables represent the Company’s financial assets (in thousands), measured at fair value on a recurring basis:



October 3, 2015	Adjusted Basis Cost		Gross Unrealized Gains		Gross Unrealized (Losses)		Estimated Fair Value		Cash and Cash Equivalents

Accounts Receivable and Allowance for Doubtful Accounts

Accounts receivable consist of trade receivables recorded upon recognition of revenue for product revenues, reduced by reserves for estimated bad debts and returns. Trade accounts receivable are recorded at the invoiced amount and do not bear interest. Credit is extended based on evaluation of the customer’s financial condition. Collateral is generally not required. The allowance for doubtful accounts is determined based on historical write-off experience, current customer information and other relevant factors, including specific identification of past due accounts, based on the age of the receivable in excess of the contemplated or contractual due date. Accounts are charged off against the allowance when the Company believes they are uncollectible.

Inventories

Inventories are stated at the lower of cost or market. Cost is determined using a standard cost method, which approximates FIFO (first in, first out) and includes material, labor and overhead costs. Inventory reserves are recorded for inventory items that have become excess or obsolete or are no longer used in current production and for inventory items that have a market price less than carrying value.

Property and Equipment

Property and equipment are stated at cost. Depreciation is calculated using the straight-line method over estimated useful lives as follows:



	Useful Lives
Buildings	39 years
Building and land improvements	7 to 10 years
Leasehold improvements	Lesser of useful life or term of lease
Machinery and equipment	5 years
Vehicles	5 years
Tooling	3 years
Computer equipment	2 to 6 years
Furniture and office equipment	2 to 6 years
Demonstration units	3 years

Land is not depreciated and construction-in-progress is not depreciated until placed in service. Normal repair and maintenance costs are expensed as incurred, whereas significant improvements that materially increase values or extend useful lives are capitalized and depreciated over the remaining estimated useful lives of the related assets. Upon sale or retirement of depreciable assets, the related cost and accumulated depreciation or amortization are removed from the accounts and any gain or loss on the sale or retirement is recognized in income.

For the nine months ended October 3, 2015 and September 27, 2014 , depreciation and amortization expense of property and equipment was $8.6 million and $6.8 million , respectively.

Intangible Assets

The Company’s policy is to renew its patents and trademarks. Total renewal costs for patents and trademarks were $0.2 million for both the three months ended October 3, 2015 and September 27, 2014, respectively. Total renewal costs for patents and trademarks were $0.5 million for each of the nine months ended October 3, 2015 and September 27, 2014 . As of October 3, 2015 , the weighted-average number of years until the next renewal was one year for patents and five years for trademarks. Costs to renew patents and trademarks are capitalized and amortized over the remaining useful life of the intangible asset. The Company continually evaluates the amortization period and carrying basis of patents and trademarks to determine whether any events or circumstances warrant a revised estimated useful life or reduction in value. Capitalized application costs are charged to operations when it is determined that the patent or trademark will not be obtained or is abandoned.

Impairment of Goodwill, Intangible Assets and Other Long-Lived Assets

Goodwill is recorded as the difference, if any, between the aggregate consideration paid for an acquisition and the fair value of the acquired net tangible and intangible assets. Goodwill is not amortized, but instead is tested annually for impairment, or more frequently when events or changes in circumstances indicate that goodwill might be impaired. In assessing goodwill impairment for each of its reporting units, the Company has the option to first assess the qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. The Company’s qualitative assessment of the recoverability of goodwill considers various macroeconomic, industry-specific and Company-specific factors, including: (i) severe adverse industry or economic trends; (ii) significant Company-specific actions; (iii) current, historical or projected deterioration of the Company’s financial performance; or (iv) a sustained decrease in the Company’s market capitalization below its net book value. If, after assessing the totality of events or circumstances, the Company determines it is unlikely that the fair value of a reporting unit is less than its carrying amount, then performing the two-step impairment test is unnecessary. However, if the Company concludes otherwise, then the Company is required to perform the first step of the two-step impairment test by comparing the fair value of the reporting unit, determined using future projected discounted operating cash flows, with its carrying amount, including goodwill. If the fair value of the reporting unit exceeds its carrying amount, goodwill is not considered impaired; otherwise, goodwill is considered impaired and the loss is measured by performing step two. Under step two, the impairment loss is measured by comparing the implied fair value of the reporting unit goodwill with the carrying amount of goodwill. The Company also has the option to bypass the qualitative assessment and proceed directly to performing the first step of the two-step goodwill impairment test. The Company may resume performing the qualitative assessment in any subsequent period. The annual impairment test is performed during the fourth fiscal quarter.

The Company reviews long-lived assets and identifiable intangibles for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to the future undiscounted operating cash flow expected to be generated by the asset. If such asset is considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount exceeds the fair value of the asset. Long-lived assets to be disposed of are reported at the lower of carrying amount or fair value less costs to sell.

No impairment of goodwill, intangible assets or other long-lived assets was recorded during the three and nine months ended October 3, 2015 or September 27, 2014 .

Revenue Recognition and Deferred Revenue

The Company follows the current authoritative guidance for revenue recognition. Based on these requirements, the Company recognizes revenue from the sale of products or services when: (i) persuasive evidence of an arrangement exists, (ii) delivery has occurred or services have been rendered, (iii) the price is fixed or determinable, and (iv) collectability is reasonably assured. In the case of the license or sale of software that does not function together with hardware components to provide the essential functionality of the hardware, revenue is recognized pursuant to the software revenue recognition guidance.

The Company derives the majority of its revenue from four primary sources: (i) direct sales under long-term sensor purchase agreements with end-user hospitals where the Company provides up-front monitoring equipment at no up-front charge in exchange for a multi-year sensor purchase commitment, (ii) other direct sales of noninvasive monitoring solutions to end-user hospitals, emergency medical response organizations and other direct customers; (iii) sales of noninvasive monitoring solutions to distributors who then typically resell to end-user hospitals, emergency medical response organizations and other direct

customers, many of which have long-term sensor purchase agreements with the Company; and (iv) sales of integrated circuit boards and consumables to original equipment manufacturer (OEM) customers who incorporate the Company’s circuit boards and embedded software technology into their multi-parameter monitoring devices and resell the consumables.

The Company enters into agreements to sell its noninvasive monitoring solutions and services, sometimes as part of multiple deliverable arrangements that include various combinations of products and services. While the majority of the Company’s sales transactions contain standard business terms and conditions, there are some transactions that contain non-standard business terms and conditions. As a result, contract interpretation and analysis is sometimes required to determine the appropriate accounting, including: (i) how the arrangement consideration should be allocated among the deliverables when multiple deliverables exist, (ii) when to recognize revenue on the deliverables, and (iii) whether undelivered elements are essential to the functionality of the delivered elements. Changes in judgments on these assumptions and estimates could materially impact the timing of revenue recognition.

In the case of multiple deliverable arrangements, the authoritative guidance provides a hierarchy to determine the selling price to be used for allocating revenue to deliverables as follows: (i) vendor-specific objective evidence of fair value (VSOE), (ii) third-party evidence of selling price (TPE), and (iii) best estimate of the selling price (ESP). VSOE is defined as the price charged when the same element is sold separately. VSOE generally exists only when the deliverable is sold separately and is the price actually charged for that deliverable. TPE generally does not exist for the majority of the Company’s products. The objective of ESP is to determine the price at which the Company would transact a sale if the product was sold on a stand-alone basis. In the absence of VSOE and TPE, the Company determines ESP for its products by considering multiple factors, including but not limited to features and functionality of the product, geographies, type of customer, contractual prices pursuant to Group Purchasing Organization (GPO) contracts, the Company’s pricing and discount practices and market conditions.

A deliverable in an arrangement qualifies as a separate unit of accounting if the delivered item has value to the customer on a stand-alone basis. Most of the Company’s products in a multiple deliverable arrangement qualify as separate units of accounting. In the case of the Company’s monitoring equipment containing embedded Masimo SET ^® or rainbow ^® SET software, the Company has determined that the hardware and software components function together to deliver the equipment’s essential functionality and, therefore, represent a single deliverable. However, software deliverables, such as rainbow ^® parameter software, which do not function together with hardware components to provide the equipment’s essential functionality, are accounted for under software revenue recognition guidance. The revenue for these multiple-element arrangements is allocated to the software deliverables and the non-software deliverables based on the relative selling prices of all of the deliverables in the arrangement using the hierarchy in the revenue recognition accounting guidance for arrangements with multiple deliverables.

Sales under long-term sensor purchase contracts are generally structured such that the Company agrees to provide at no up-front charge certain monitoring equipment, software, installation, training and/or warranty support in exchange for the hospital’s agreement to purchase sensors over the term of the agreement, which generally ranges from three to seven years. The sensors are essential to the functionality of the monitoring equipment and, therefore, represent a substantive performance obligation. The Company does not recognize any revenue when the monitoring and related equipment and software are delivered to the hospitals. The Company recognizes revenue for these delivered elements on a pro-rata basis when installation and training are complete, as the sensors are delivered under the long-term purchase commitment. The cost of the monitoring equipment initially placed at the hospitals is deferred and amortized to cost of goods sold over the life of the underlying long-term sensor purchase contract.

Many of the Company’s distributors purchase sensor products which they then resell to end-user hospitals that are typically fulfilling their purchase obligations to the Company under such end-user hospital’s long-term sensor purchase commitments. Upon shipment to the distributor, revenue is deferred until the distributor ships the product to the Company’s end-user customers based on an estimate of the inventory held by these distributors at the end of the accounting period.

The Company also earns revenue from the sale of integrated circuit boards and other products, as well as from rainbow ^® parameter software licenses, to OEMs under various agreements. Revenue from the sale of products to the OEMs is generally recognized at the time of shipment. Revenue related to software licenses to OEMs is generally recognized upon shipment of the OEM’s product to its customers, as represented to the Company by the OEM.

The Company also provides certain customers with the ability to purchase sensors under rebate programs. Under these programs, the customers may earn rebates based on their purchasing activity. The Company estimates and provides allowances for these programs at the time of sale as a reduction to revenue.

In general, customers do not have a right of return for credit or refund. However, the Company allows returns under certain circumstances. At the end of each period, the Company estimates and accrues for these returns as a reduction to revenue and accounts receivable. The Company estimates returns based on several factors, including contractual limitations and past returns history.

The Company’s royalty revenue arises from one agreement with Medtronic plc (Medtronic, formerly Covidien), and is due and payable quarterly based on U.S. sales of Medtronic’s infringing products. An estimate of these royalty revenues is recorded quarterly in the period earned based on the prior quarter’s historical results, adjusted for any new information or trends known to management at the time of estimation. This estimated revenue is adjusted prospectively when the Company receives the royalty report from Medtronic, approximately 60 days after the end of the previous quarter.

Product Warranty

The Company generally provides a warranty against defects in material and workmanship for a period ranging from six to fourteen months, depending on the product type. In the case of long-term sales agreements, the Company typically warrants the products for the term of the agreement, which generally ranges from three to seven years. In traditional sales activities, including direct and OEM sales, the Company establishes an accrual for the estimated costs of warranty at the time of revenue recognition. Estimated warranty expenses are recorded as an accrued liability, with a corresponding provision to cost of sales. In long-term sales agreements, revenue related to extended warranty is recognized over the life of the contract, while the product warranty costs related to the long-term sales agreements are expensed as incurred.

Changes in the product warranty accrual were as follows (in thousands):



	Nine Months Ended
	October 3, 2015			September 27, 2014
Warranty accrual, beginning of period	$	1,416		$	1,161

Settlements made	(828		)	(812		)
Warranty accrual, end of period	$	1,215		$	1,058

Litigation Costs and Contingencies

The Company records a charge equal to at least the minimum estimated liability for a loss contingency or litigation settlement when both of the following conditions are met: (i) information available prior to issuance of the financial statements indicates that it is probable that a liability had been incurred at the date of the financial statements, and (ii) the range of loss can be reasonably estimated. The determination of whether a loss contingency or litigation settlement is probable or reasonably possible involves a significant amount of management judgment, as does the estimation of the range of loss given the nature of contingencies. Liabilities related to litigation settlements with multiple elements are recorded based on the fair value of each element. Legal and other litigation related expenses are recognized as the services are provided. The Company records insurance and other indemnity recoveries for litigation expenses when both of the following conditions are met: (a) the recovery is probable, and (b) collectability is reasonably assured. Insurance recoveries are only recorded to the extent the litigation costs to which they relate have been incurred and recognized in the financial statements.

Comprehensive Income

Authoritative accounting guidance establishes requirements for reporting and disclosure of comprehensive income and its components. Comprehensive income includes foreign currency translation adjustments and any related tax benefits that have been excluded from net income including noncontrolling interest, and reflected in Masimo Corporation stockholders’ equity.

Net Income Per Share

Basic net income per share attributable to Masimo Corporation for the three and nine months ended October 3, 2015 and September 27, 2014 is computed by dividing net income attributable to Masimo Corporation stockholders by the weighted-average number of shares outstanding during each period. The diluted net income per share attributable to Masimo Corporation stockholders for the three and nine months ended October 3, 2015 and September 27, 2014 is computed by dividing the net income attributable to Masimo Corporation stockholders by the weighted-average number of shares and potential shares outstanding during each period, if the effect of potential shares is dilutive. Potential shares include incremental shares of stock issuable upon the exercise of stock options. For the three and nine months ended October 3, 2015 , weighted options to purchase approximately 0.5 million and 0.6 million shares of common stock, respectively, were outstanding, but were not included in the computation of diluted net income per share because the effect of including such shares would have been antidilutive in the applicable period. For the three and nine months ended September 27, 2014 , weighted options to purchase approximately 3.1 million and 1.5 million shares of common stock, respectively, were outstanding, but were not included in the computation of diluted net income per share because the effect of including such shares would have been antidilutive in the applicable period. Based on authoritative accounting guidance, the Company adjusted its net income including noncontrolling interest by the amount of net (income) loss attributable to the noncontrolling interest for the three and nine months ended October 3, 2015 and September 27, 2014 , to determine its net income attributable to its stockholders. A reconciliation of basic and diluted net income per share attributable to Masimo Corporation stockholders is as follows (in thousands, except per share amounts):

Seasonality

The healthcare business in the United States and overseas is subject to quarterly fluctuations in hospital and other alternative care admissions. Historically, the Company has typically experienced higher product revenues during the traditional “flu season” that often increases hospital and acute care facility admissions in the Company’s first and fourth fiscal quarters. At the same time, the Company has often experienced a sequential decline in product revenues in its second and third fiscal quarters primarily due to the summer vacation season during which people tend to avoid and/or delay elective procedures. Because the Company’s non-sales variable operating expenses often do not fluctuate in the same manner as its quarterly product sales, its quarterly operating income may fluctuate disproportionately to its quarterly revenue.

Recently Issued Accounting Pronouncements

In August 2015, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update No. 2015-15, Interest - Imputation of Interest (Subtopic 832-30): Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line of Credit Arrangements - Amendments to SEC Paragraphs Pursuant to Staff Announcement June 18, 2015 EITF Meeting (ASU 2015-15) . ASU 2015-15 clarifies the treatment of debt issuance costs associated with line-of-credit arrangements upon the adoption of ASU 2015-03 (as discussed below). In particular, ASU 2015-15 clarifies that the SEC staff would not object to an entity deferring and presenting debt issuance costs as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. ASU 2015-15 will become effective upon the Company’s adoption of ASU 2015-03.The Company does not expect that its adoption of this standard will have a material impact on its consolidated financial statements.

In July 2015, the FASB issued Accounting Standards Update No. 2015-11, Simplifying the Measurement of Inventory (Topic 330) . The new standard provides guidance that simplifies the subsequent measurement of inventories by replacing the current lower of cost or market test with a lower of cost and net realizable value test, where net realizable value is defined as the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. The guidance applies only to inventories for which cost is determined by methods other than last-in first-out and the retail inventory method. ASU-2015-11 is effective for interim and annual periods beginning after December 15, 2016. Early application is permitted, and should be applied prospectively. The Company is currently evaluating this standard but does not expect that its adoption will have a material impact on its consolidated financial statements.

In April 2015, the FASB issued Accounting Standards Update No. 2015-03, Interest-Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs (ASU 2015-03). The new standard requires that debt issuance costs related to a recognized debt liability be presented on the balance sheet as a direct deduction from the carrying amount of the related debt liability instead of being presented as an asset. ASU 2015-03 requires retrospective application and represents a change in accounting principle. ASU 2015-03 is effective for fiscal years beginning after December 15, 2015. Early adoption is permitted for financial statements that have not been previously issued. The Company does not expect that its adoption of this standard will have a material impact on its consolidated financial statements.

In February 2015, the FASB issued Accounting Standards Update No. 2015-02, Consolidation (Topic 810): Amendments to the Consolidation Analysis (ASU 2015-02). The amended standard applies to entities in all industries and eliminates the deferral of certain consolidation standards for entities considered to be investment companies as well as modifies the consolidation analysis performed on certain types of legal entities. ASU 2015-02 is effective for annual and interim fiscal reporting periods beginning after December 15, 2015, and may be applied retrospectively, with early application permitted. The Company is continuing to evaluate the expected impact of this standard on its consolidated financial statements.

In May 2014, the FASB issued Accounting Standards Update No. 2014-09, Revenue (Topic 606): Revenue from Contracts with Customer (ASU 2014-09) . The new standard provides a single, principles-based five-step model to be applied to all contracts with customers while enhancing disclosures about revenue, providing additional guidance for transactions that were not previously addressed comprehensively and improving guidance for multiple-element arrangements. ASU 2014-09 will replace most existing revenue recognition guidance under GAAP when it becomes effective. The standard permits the use of either the retrospective or cumulative effect transition method upon adoption. In August 2015, the FASB issued Accounting Standards Update No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date , which amended ASU 2014-09, providing for a one year deferral period for the implementation of ASU 2014-09. ASU 2014-09 will now be effective for annual and interim periods beginning on or after December 15, 2017. The Company is continuing to evaluate the expected impact of this standard on its consolidated financial statements.

3. Cash and Cash Equivalents

The Company considers all highly liquid investments with an original maturity from date of purchase of three months or less , or highly liquid investments that are readily convertible into known amounts of cash, to be cash equivalents. As of October 3, 2015 , the Company’s cash balance was $84.9 million , which was primarily comprised of checking accounts. Additionally, the Company had cash equivalents of $18.7 million , which consisted of $17.5 million of bank time deposits and $1.2 million of money market funds. As of January 3, 2015 , the Company’s cash balance was $92.9 million , comprised primarily of checking accounts. Additionally, the Company had cash equivalents of $41.6 million , consisting of $40.5 million of bank time deposits and $1.1 million of money market funds.

4. Variable Interest Entity (VIE)

The Company follows authoritative guidance for the consolidation of its VIE, which requires an enterprise to determine whether its variable interest gives it a controlling financial interest in a VIE. Determination about whether an enterprise should consolidate a VIE is required to be evaluated continuously as changes to existing relationships or future transactions may result in consolidating or deconsolidating the VIE.

Cercacor Laboratories, Inc. (Cercacor)

Cercacor is an independent entity spun off from the Company to its stockholders in 1998. Joe Kiani, the Company’s Chairman and Chief Executive Officer, is also the Chairman and Chief Executive Officer of Cercacor. The Company is a party to a Cross-Licensing Agreement with Cercacor, which was most recently amended and restated effective January 1, 2007 (the Cross-Licensing Agreement), that governs each party’s rights to certain intellectual property held by the two companies. In addition, the Company entered into a Services Agreement with Cercacor effective January 1, 2007, which governs the general and administrative services the Company provides to Cercacor.

Under the Cross-Licensing Agreement, the Company granted Cercacor an exclusive, perpetual and worldwide license, with sublicense rights, to use all Masimo SET ^® owned by the Company, including all improvements on this technology, for the monitoring of non-vital signs measurements and to develop and sell devices incorporating Masimo SET ^® for monitoring non-vital signs measurements in any product market in which a product is intended to be used by a patient or pharmacist rather than a professional medical caregiver. The Company refers to this market as the Cercacor Market. The Company also granted Cercacor a non-exclusive, perpetual and worldwide license, with sublicense rights, to use all Masimo SET ^® for the measurement of vital signs in the Cercacor Market.

The Company exclusively licenses from Cercacor the right to make and distribute products in the professional medical caregiver markets, which the Company refers to as the Masimo Market, that utilize rainbow ^® technology for certain non-invasive measurements, including carbon monoxide, methemoglobin, fractional arterial oxygen saturation and hemoglobin. The Company also has the option to obtain exclusive licenses to make and distribute products that utilize rainbow ^® technology for the monitoring of other non-vital signs measurements, including blood glucose, in product markets where the product is intended to be used by a professional medical caregiver. During the year ended December 28, 2013, the Company exercised its right to license from Cercacor five additional non-vital sign measurements for $0.5 million each, or $2.5 million in the

aggregate. As the result of new data related to these five additional non-vital sign measurements, the Company and Cercacor terminated these licenses during the three months ended October 3, 2015 and Cercacor agreed to refund the amounts previously paid by the Company for these licenses.

To date, the Company has developed and commercially released devices that measure carbon monoxide, methemoglobin and hemoglobin using licensed rainbow ^® technology. The Company also markets certain other rainbow technologies, such as rainbow Acoustic Monitoring ^™ , the rights to which are owned by the Company and for which no licensing fee is paid to Cercacor.

The Company’s license to rainbow ^® technology for these parameters in these markets is exclusive on the condition that the Company continues to pay Cercacor royalties on its products incorporating rainbow ^® technology, subject to certain minimum aggregate royalty thresholds, and that the Company uses commercially reasonable efforts to develop or market products incorporating the licensed rainbow ^® technology. The royalty rate is up to 10% of the rainbow ^® royalty base, which includes handhelds, tabletop and multi-parameter devices. Handheld products incorporating rainbow ^® technology will carry up to a 10% royalty rate. For other products, only the proportional amount attributable to that portion of the Company’s devices used to monitor non-vital signs measurements, rather than to monitor vital signs measurements, and sensors and accessories for measuring only non-vital signs parameters, will be included in the 10% rainbow ^® royalty base. Effective January 2009, for multi-parameter devices, the rainbow ^® royalty base includes the percentage of the revenue based on the number of rainbow ^® enabled measurements. For hospital contracts where the Company places equipment and enters into a sensor contract, the Company pays a royalty to Cercacor on the total sensor contract revenues based on the ratio of rainbow ^® enabled devices to total devices.

The current annual minimum aggregate royalty obligation under the license is $5.0 million . Actual aggregate royalty liabilities to Cercacor under the license were $1.7 million and $4.3 million for the three and nine months ended October 3, 2015 , respectively, and $0.9 million and $4.0 million for the three and nine months ended September 27, 2014 , respectively. In connection with a change in control of the Company, as defined in the Cross-Licensing Agreement, the minimum aggregate annual royalties for licensed rainbow ^® measurements payable to Cercacor related to carbon monoxide, methemoglobin, fractional arterial oxygen saturation, hemoglobin and blood glucose will increase to $15.0 million , plus up to $2.0 million for other rainbow ^® measurements.

In February 2009, in order to accelerate the product development of an improved hemoglobin spot-check measurement device, Pronto-7 ^® , the Company’s board of directors agreed to fund additional engineering expenses of Cercacor. Specifically, these expenses included third-party engineering materials and supplies expense as well as 50% of Cercacor’s total engineering and engineering-related payroll expenses. Beginning in 2012, the Company’s board of directors approved an increase in the percentage of Cercacor’s total engineering and engineering-related payroll expenses funded by the Company from 50% to 60% . This arrangement was discontinued by mutual agreement effective as of January 4, 2015. During the three and nine months ended September 27, 2014 , the expenses for these additional services, materials and supplies totaled $0.8 million and $2.6 million , respectively. During the three months ended October 3, 2015 , Cercacor completed a review of its fiscal 2014 cross-charges related to Pronto-7 ^® . Based on this review, it was determined that less than 60% of Cercacor’s total engineering and engineering-related payroll expenses were attributable to the development of Pronto-7 ^® , resulting in an overpayment by the Company of approximately $1.6 million. Both parties also reviewed and agreed to equally share approximately $1.4 million of previously incurred engineering-related payroll expenses associated with research for a new LED sensor technology. As a result, the parties mutually agreed that Cercacor would refund $0.9 million to the Company in the quarter ended October 3, 2015 .

Effective as of July 6, 2015, the Company and Cercacor entered into a patent transfer and licensing agreement (the Patent Agreement) pursuant to which, among other things, the Company purchased certain patents from Cercacor (the Purchased Patents) for an aggregate purchase price of $2.4 million . Pursuant to the Patent Agreement, the Company granted Cercacor an irrevocable, non-exclusive, worldwide license with respect to the products and services covered by the Purchased Patents.

Pursuant to authoritative accounting guidance, Cercacor is consolidated within the Company’s financial statements for all periods presented. The Company is required to consolidate Cercacor since the Company is currently deemed to be the primary beneficiary of Cercacor’s activities. This determination is based primarily on the facts that the Company is Cercacor’s sole customer and Cercacor is currently financially dependent on the Company for funding. Accordingly, all intercompany royalties, option and license fees and other charges between the Company and Cercacor, as well as all intercompany payables and receivables, have been eliminated in the consolidation. Also, all direct engineering expenses that have been incurred by the Company and charged to Cercacor, or that have been incurred by Cercacor and charged to the Company, have not been eliminated and are included as research and development expense in the Company’s condensed consolidated statements of

In September 2014, the Company executed Amendment No. 1 to Credit Agreement (Amendment 1) with JPMorgan Chase Bank, N.A., as Administrative Agent and a Lender (JPMorgan), and Bank of America, N.A., as a Lender (BofA). Amendment 1 modified the credit agreement dated April 23, 2014, by and among the Company, the Lenders from time to time party thereto and JPMorgan (the Credit Agreement and collectively with Amendment 1, the Amended Credit Agreement). The Amended Credit Agreement increased the Company’s borrowing capacity by $125.0 million , bringing the total available borrowing capacity to $250.0 million with an option, subject to certain conditions, for the Company to increase the aggregate borrowing capacity up to $350.0 million in the future. The Amended Credit Agreement also provides for a sublimit of up to $50.0 million for the issuance of letters of credit and a sublimit of $75.0 million for borrowings in specified foreign currencies. All unpaid principal under the Amended Credit Agreement will become due and payable on September 29, 2019.

Borrowings under the Amended Credit Agreement will be deemed, at the Company’s election, either: (i) an ABR Loan, which bears interest at the Alternate Base Rate (as defined below), plus a spread (ABR Spread) based upon a Company leverage ratio, or (ii) a Eurodollar Loan, which bears interest at the Adjusted LIBO Rate (as defined below), plus a spread (Eurodollar Spread) based upon a Company leverage ratio. The ABR Spread is 0.125% to 1.00% and the Eurodollar Spread is 1.125% to 2.000% . Subject to certain conditions, the Company may also request swingline loans from time to time (Swingline Loans) that bear interest similar to an ABR Loan.

The Alternate Base Rate is determined by taking the greatest of (i) the prime rate, (ii) the federal funds effective rate plus 0.50% , and (iii) the one-month Adjusted LIBO Rate plus 1.0% . The Adjusted LIBO Rate is equal to LIBOR for the applicable interest period multiplied by the statutory reserve rate for such period.

The Company is obligated under the Amended Credit Agreement to pay a fee ranging from 0.175% to 0.300% per annum, based upon a Company leverage ratio, with respect to any unused portion of the line of credit. This fee and interest on any ABR Loan are due and payable quarterly in arrears. Interest on any Eurodollar Loan is due and payable at the end of the applicable interest period (or at each three month interval in the case of loans with interest periods greater than three months). Interest on any Swingline Loan is due and payable on the date that the Swingline Loan is required to be repaid. The Company may prepay the loans and terminate the commitments in whole at any time, without premium or penalty, subject to reimbursement of certain costs in the case of Eurodollar Loans.

Pursuant to the terms of the Amended Credit Agreement, the Company is subject to certain covenants, including financial covenants related to a leverage ratio and an interest charge coverage ratio, and other customary negative covenants. The Company’s obligations under the Amended Credit Agreement are secured by substantially all of the Company’s personal property, including certain equity interests in U.S. domestic and first-tier foreign subsidiaries.

As of October 3, 2015 , the Amended Credit Agreement had outstanding Eurodollar Loan draws totaling $190.0 million at an effective interest rate of 1.50% , and the Company was in compliance with all covenants under the Amended Credit Agreement.

11. Stock Repurchase Programs

In February 2013, the Company’s board of directors authorized the repurchase of up to 6.0 million shares of the Company’s common stock under a stock repurchase program. In October 2014, the Company’s board of directors increased the number of shares of the Company’s common stock authorized for repurchase by 3.0 million shares, bringing the total number of shares of the Company’s common stock authorized under such repurchase program from inception to 9.0 million . The stock repurchase program provided that it may be carried out at the discretion of a committee comprised of the Company’s Chief Executive Officer and Chief Financial Officer through open market purchases, one or more Rule 10b5-1 trading plans, block trades and in privately negotiated transactions.

During the three months ended October 3, 2015 , approximately 1.2 million shares were repurchased at an average cost of $41.44 per share for a total repurchase cost of $48.5 million . During the nine months ended October 3, 2015 , approximately 3.5 million shares were repurchased at an average cost of $36.71 per share for a total repurchase cost of $130.2 million . During the three and nine months ended September 27, 2014 , approximately 2.4 million shares were repurchased at an average cost of $21.95 per share for a total repurchase cost of $52.7 million . As of October 3, 2015 , all of the authorized 9.0 million shares had been repurchased under this program.

In September 2015, the Board authorized a new stock repurchase program, whereby the Company may purchase up to 5.0 million shares of its common stock over a period of up to three years. As of October 3, 2015 , 5.0 million shares remained authorized for repurchase under this program. The stock repurchase program may be carried out at the discretion of a committee comprised of the Company’s Chief Executive Officer and Chief Financial Officer through open market purchases, one or more Rule 10b5-1 trading plans, block trades and in privately negotiated transactions.

immediate share issuance under the Chief Executive Officer's prior employment agreement if he was terminated by the Company, if he terminated his employment for good reason under certain circumstances or if there was a change in control of the Company. This employment agreement was restated by a new employment agreement, dated November 4, 2015, that eliminated certain of the foregoing provisions. Please see Note 16 below.

The Black-Scholes option pricing model is used to estimate the fair value of options granted under the Company’s share-based compensation plans. The range of assumptions used and the resulting weighted-average fair value of options granted at the date of grant were as follows:



	Three Months Ended		Nine Months Ended
	October 3, 2015	September 27, 2014	October 3, 2015	September 27, 2014
Risk-free interest rate	1.5% to 1.8%	1.6% to 1.8%	1.3% to 1.9%	1.4% to 1.8%
Expected term (in years)	5.5	5.1	5.5	5.1
Estimated volatility	32.3% to 35.6%	31.7% to 32.1%	32.0% to 37.4%	31.7% to 33.1%
Expected dividends	0%	0%	0%	0%
Weighted-average fair value of options granted	$14.09	$6.79	$11.82	$7.85

The total share-based compensation expense for the three and nine months ended October 3, 2015 was $2.7 million and $8.1 million , respectively. The total share-based compensation expense for the three and nine months ended September 27, 2014 was $2.6 million and $7.8 million , respectively.

The aggregate intrinsic value of options is calculated as the positive difference, if any, between the market value of the Company’s common stock on the date of exercise or the respective period end, as appropriate, and the exercise price of the options. The aggregate intrinsic value of options outstanding, with an exercise price less than the closing price of the Company’s common stock, as of October 3, 2015 was $52.5 million . The aggregate intrinsic value of options exercisable, with an exercise price less than the closing price of the Company’s common stock, as of October 3, 2015 was $22.5 million . The aggregate intrinsic value of options exercised during the three and nine months ended October 3, 2015 was $10.0 million and $21.6 million , respectively.

The unrecognized share-based compensation expense related to unvested options granted after January 1, 2006 was $23.3 million as of October 3, 2015 . The weighted-average remaining contractual term of options outstanding, with an exercise price less than the closing price of the Company’s common stock, as of October 3, 2015 was 5.8 years. The weighted-average remaining contractual term of options exercisable, with an exercise price less than the closing price of the Company’s common stock, as of October 3, 2015 was 4.2 years.

13. Commitments and Contingencies

Leases

The Company leases certain facilities in North America, Europe and Asia under operating lease agreements expiring at various dates through December 2020 . Certain facility leases contain predetermined price escalations and in some cases renewal options. The Company recognizes the lease costs using a straight-line method based on total lease payments. The Company has received leasehold improvement incentives in connection with certain leased facilities in the U.S. These leasehold improvement incentives have been recorded as deferred rent and are being amortized as a reduction to rent expense on a straight-line basis over the life of the lease. As of October 3, 2015 and January 3, 2015 , rent expense accrued in excess of the amount paid aggregated $0.2 million and $0.4 million , respectively, which is classified as other liabilities in the accompanying condensed consolidated balance sheets. In addition, the Company leases automobiles in Europe that are classified as operating leases and expire at various dates through October 2019 . The majority of these leases are non-cancellable. The Company also has outstanding capital leases for office equipment and computer equipment, all of which are non-cancellable.

Employment and Severance Agreements

As of October 3, 2015 , the Company had an employment agreement with its Chief Executive Officer (CEO) that provides for an aggregate annual base salary with annual increases at the discretion of the Compensation Committee of the Company’s board of directors. The employment agreement provided for an annual bonus based on the Company’s attainment of certain objectives and goals. The agreement had an initial term of three years, with automatic daily renewal, unless either the Company or the CEO notified the other party of non-renewal of the agreement. Also, under this employment agreement, the CEO was entitled to receive certain salary, equity, tax, medical and life insurance benefits with an estimated value of approximately $80.9 million as of October 3, 2015, as well as reimbursement of certain tax withholdings and excise tax gross-up amounts collectively estimated at approximately $125.0 million as of October 3, 2015, if he was terminated by the Company, if he terminated his employment for good reason under certain circumstances or if there was a change in control of the Company. This employment agreement was restated by a new employment agreement, dated November 4, 2015, that eliminated the foregoing tax withholding reimbursement and excise tax gross-up provisions. Please see Note 16 below.

As of October 3, 2015 , the Company had severance plan participation agreements with seven other executive officers. The participation agreements (the Agreements) are governed by the terms and conditions of the Company’s 2007 Severance Protection Plan (the Severance Plan), which became effective on July 19, 2007 and which was amended effective December 31, 2008. Under each of the Agreements, the applicable executive officer may be entitled to receive certain salary, equity, medical and life insurance benefits if he is terminated by the Company without cause or if he terminates his employment for good reason under certain circumstances. The executive officers are also required to give the Company six months advance notice of their resignation under certain circumstances.

Purchase Commitments

Pursuant to contractual obligations with vendors, the Company had $85.5 million of purchase commitments as of October 3, 2015 , which are expected to be purchased within one year.

Other Contractual Commitments

In the normal course of business, the Company may provide bank guarantees to support government hospital tenders in certain foreign jurisdictions. As of October 3, 2015 , the Company had approximately $0.3 million in unsecured bank guarantees.

In certain circumstances, the Company also provides limited indemnification within its various customer contracts whereby the Company indemnifies the parties to whom it sells its products with respect to potential infringement of intellectual property, and against bodily injury caused by a defective Company product. It is not possible to predict the maximum potential amount of future payments under these or similar agreements, due to the conditional nature of the Company’s obligations and the unique facts and circumstances involved. As of October 3, 2015 , the Company has not incurred any significant costs related to contractual indemnification of its customers.

Concentrations of Risk

The Company is exposed to credit loss for the amount of its cash deposits with financial institutions in excess of federally insured limits. The Company invests its excess cash deposits in U.S. Treasury bills and money market accounts with major financial institutions. As of October 3, 2015 , the Company had $84.9 million of bank balances, of which $2.3 million was covered by either the U.S. Federal Deposit Insurance Corporation limit or foreign countries’ deposit insurance organizations. As of October 3, 2015 , the Company had $1.2 million in money market funds and $17.5 million of bank time deposits that are not guaranteed by the U.S. Federal government.

While the Company and its contract manufacturers rely on sole source suppliers for certain components, steps have been taken to minimize the impact of a shortage or stoppage of shipments, such as maintaining a safety stock of inventory and designing products that could be modified to use different components. However, there can be no assurance that a shortage or stoppage of shipments of the materials or components that the Company purchases will not result in a delay in production or adversely affect the Company’s business.

The Company’s ability to sell its products to U.S. hospitals depends in part on its relationships with GPOs. Many existing and potential customers for the Company’s products become members of GPOs. GPOs negotiate pricing arrangements and contracts, sometimes exclusively, with medical supply manufacturers and distributors, and these negotiated prices are made available to a GPO’s affiliated hospitals and other members. During the three and nine months ended October 3, 2015 , revenue from the sale of the Company’s products to U.S. hospitals that are members of GPOs amounted to $81.0 million and $251.9 million , respectively. During the three and nine months ended September 27, 2014 , revenue from the sale of the Company’s products to U.S. hospitals that are members of GPOs amounted to $75.2 million and $228.9 million , respectively. As of October 3, 2015 , three different just-in-time distributors represented 9% , 8% and 5% of the Company’s accounts receivable balance, respectively. As of January 3, 2015 , three different just-in-time distributors represented 9% , 6% and 5% of the Company’s accounts receivable balance, respectively.

For the three months ended October 3, 2015 , the Company had sales through two just-in-time distributors, which each represented 15% and 12% of total revenue, respectively. For the three months ended September 27, 2014 , the Company had sales through two just-in-time distributors, which each represented 14% and 12% of total revenue, respectively.

For the nine months ended October 3, 2015 , the Company had sales through two just-in-time distributors, which each represented 15% and 12% of total revenue, respectively. For the nine months ended September 27, 2014 , the Company also had sales through two just-in-time distributors, which each represented 14% and 11% of total revenue, respectively. For the three and nine months ended October 3, 2015 , the just-in-time distributors took and fulfilled orders from the Company’s direct customers, many of whom have signed long-term sensor agreements with the Company.

For the three months ended October 3, 2015 and September 27, 2014 , the Company recorded $8.0 million and $7.0 million , respectively, in royalty revenues from Medtronic pursuant to the original settlement agreement and amendments. For the nine months ended October 3, 2015 and September 27, 2014 , the Company recorded $23.3 million and $22.0 million , respectively, in royalty revenues from Medtronic pursuant to the original settlement agreement and amendments. In exchange for these royalty payments, the Company has provided Medtronic the ability to ship its patent infringing product with a covenant not to sue Medtronic as long as Medtronic abides by the terms of the agreement. The current royalty rate is 7.75% and the amended agreement can be terminated by Medtronic upon 60 days written notice.

Litigation

On February 3, 2009, the Company filed a patent infringement suit in the U.S. District Court for the District of Delaware against Philips Electronics North America Corporation and Philips Medizin Systeme Böblingen GmbH (collectively, Philips) related to Philips’ FAST pulse oximetry technology and certain of Philips’ patient monitors. On June 15, 2009, Philips answered the Company’s complaint and Philips Electronics North America Corporation filed antitrust and patent infringement counterclaims against the Company, as well as counterclaims seeking declaratory judgments of invalidity of the patents asserted by the Company against Philips. On July 9, 2009, the Company filed its answer denying Philips’ counterclaims and asserting various defenses. The Company also asserted counterclaims against Philips for fraud, intentional interference with prospective economic advantage and for declaratory judgments of noninfringement and invalidity with respect to the patents asserted by Philips against the Company. Philips later added a claim for infringement of one additional patent. Subsequently, the Court bifurcated Philips’ antitrust claims and its patent misuse defense, as well as stayed the discovery phase on those claims pending trial in the patent case. In addition, the Company asserted additional patents in 2012, and the Court ordered that these patents and some of the originally asserted patents be tried in a second phase. On May 23, 2014, Philips filed a motion for leave to amend its answer and counterclaims to allege inequitable conduct. The Court granted Philips’ motion for leave to amend. A jury trial commenced on September 15, 2014 with respect to two of the Company’s patents and one of Philips’ patents. On October 1, 2014, the jury determined that both of the Company’s patents were valid and that the damages amount for Philips’ infringement was $466.8 million . The jury also determined that the Company did not infringe the Philips patent. The Court held a bench trial on an inequitable conduct defense raised by Philips and heard oral arguments on the post-trial motions. The Court denied Philips’ post-trial motions and found that Philips failed to prove inequitable conduct. The Court also denied a motion brought by the Company seeking judgment on the pleadings of Philips’ patent misuse defense. Philips has indicated that it intends to appeal the jury verdict. On September 18, 2015, the Court set a schedule for the trial related to the second phase patents and a schedule for the trial related to Philips’ antitrust counterclaims and patent misuse defense, with both trials scheduled to take place in the first quarter of 2017. The Company believes that it has good and substantial defenses to the antitrust and patent infringement claims asserted by Philips. The Company is unable to determine whether any loss will occur or to estimate the range of such potential loss; therefore, no amount of loss has been accrued by the Company as of the date of filing of this Quarterly Report on Form 10-Q. Furthermore, there is no guarantee that the Company will prevail in this suit or receive any damages or other relief if it does prevail.

On December 21, 2012, the Company filed suit against Mindray DS USA, Inc. and Shenzhen Mindray Bio-Medical Electronics Co, Ltd. (Shenzhen Mindray) in the U.S. District Court for the Central District of California. The complaint alleges patent infringement, breach of contract and other claims. Mindray DS USA, Inc. was dismissed from the case based on venue. On June 3, 2013, Shenzhen Mindray answered the Company’s complaint and filed antitrust and related counterclaims against the Company, as well as counterclaims seeking declaratory judgments of invalidity and non-infringement of the patents asserted by the Company against Shenzhen Mindray. On June 24, 2013, the Company filed its answer denying Shenzhen Mindray’s counterclaims and asserting various defenses. On July 17, 2013, the Court granted Shenzhen Mindray’s motion to dismiss the patent claims without prejudice to allow the Company to amend the complaint to provide additional detail supporting Shenzhen Mindray’s direct and indirect infringement of the Company’s patents. On the same day, the Court denied Shenzhen Mindray’s motion to dismiss the Company’s non-patent claims. On August 5, 2013, the Company filed a first amended complaint. On August 21, 2013, Shenzhen Mindray answered the Company’s complaint and reasserted the counterclaims it asserted on June 3, 2013, as well as two additional counterclaims alleging patent infringement. On September 16, 2013, the Company filed its answer denying Shenzhen Mindray’s counterclaims and asserting various defenses. On October 31, 2013, the Court issued a scheduling order setting a trial date of November 4, 2014. On December 10, 2013, Shenzhen Mindray filed a second amended answer and counterclaims, including a new counterclaim for tortious interference. On January 2, 2014, the Company filed a motion for judgment on the pleadings as to Shenzhen Mindray’s antitrust counterclaims and inequitable conduct counterclaims and defenses. The Court granted judgment on the pleadings with leave to amend. On March 27, 2014, Shenzhen Mindray filed a third amended answer and counterclaims. On April 10, 2014, Shenzhen Mindray filed a fourth amended answer and counterclaims. On May 5, 2014, Shenzhen Mindray filed a partial motion for summary judgment of no patent infringement, which the Court denied on June 19, 2014. On May 19, 2014, Shenzhen Mindray filed a motion for judgment on the pleadings contending that Masimo International SARL (a subsidiary of the Company), not Masimo Corporation, has standing to assert its claims relating to breach of contract. The Company opposed this motion and filed a motion to add Masimo International SARL as a plaintiff. On June 26, 2014, the Court granted the Company’s motion and denied Shenzhen Mindray’s motion. The Court also vacated the case schedule. On July 7, 2014, the Company filed a second amended complaint adding Masimo International SARL as a plaintiff. On August 18, 2014, the Court adopted the Company’s proposed case schedule, setting a new trial date of December 1, 2015. On September 24, 2015, the Court set a trial date of December 8, 2015. The parties are preparing for trial. The Company believes that it has good and substantial defenses to the antitrust, patent infringement and other counterclaims asserted by Shenzhen Mindray. The Company is unable to determine whether any loss will occur or to estimate the range of

such potential loss; therefore, no amount of loss has been accrued by the Company as of the date of filing of this Quarterly Report on Form 10-Q. Furthermore, there is no guarantee that the Company will prevail in this suit or receive any damages or other relief if it does prevail.

On March 6, 2013, Shenzhen Mindray filed a complaint against the Company under the Anti-Unfair Competition Law of the People’s Republic of China (PRC) before the Shenzhen Municipal Intermediate People’s Court, alleging violation of PRC competition laws. On March 10, 2014, the Guangdong Higher People’s Court of PRC held that the Shenzhen Court did not have jurisdiction. On December 23, 2014, the Supreme People’s Court of PRC reversed the Guangdong Court’s ruling. Following the Supreme People’s Court’s ruling, the case was remanded to the Shenzhen Court for a ruling on the merits of Shenzhen Mindray’s claims. The Shenzhen Court held a first hearing regarding the case but has not issued any decision. Shenzhen Mindray also filed a complaint in Shenzhen Intermediate People’s Court against the Company and Shenzhen Comen Medical Instruments on February 6, 2015, alleging infringement of Chinese Patent No. 00808884.5. Additionally, a separate lawsuit was filed against Masimo Sweden AB (Masimo Sweden) on the same day and in the same court alleging infringement of Chinese Patent No. 200710305061.9. Masimo Sweden was recently served with the lawsuit. The Company believes that it has good and substantial defenses to Shenzhen Mindray’s claims, but there is no guarantee that the Company will prevail in these suits. The Company is unable to determine whether any loss will occur or to estimate the range of such potential loss; therefore, no amount of loss has been accrued by the Company as of the date of filing of this Quarterly Report on Form 10-Q.

On December 10, 2013, the Company filed suit against Mindray DS USA, Inc. (Mindray USA), Shenzhen Mindray and Mindray Medical International Limited in the Superior Court of New Jersey. The complaint alleges breach of contract and related claims. In January 2014, Mindray USA removed the case to the U.S. District Court for the District of New Jersey. In February 2014, the Company filed a motion to remand the action to the Superior Court of New Jersey. In May 2014, Mindray USA filed an answer and counterclaims in the U.S. District Court asserting patent infringement and federal antitrust counterclaims. On January 7, 2015, the U.S. District Court remanded the action to the Superior Court of New Jersey. On January 22, 2015, Mindray USA filed an answer and counterclaims in the Superior Court of New Jersey asserting patent infringement and federal antitrust counterclaims, and again removed the case to the U.S. District Court for the District of New Jersey. On January 29, 2015, Mindray USA, Shenzhen Mindray and Mindray Medical International, Limited filed separate motions to dismiss the action, each of which is currently pending before the U.S. District Court. On February 23, 2015, the Company filed a motion to remand the case to the Superior Court of New Jersey, which is currently pending before the U.S. District Court. On September 1, 2015, the U.S. District Court granted-in-part the Company’s motion, remanding the Company’s state law claims and Mindray USA’s antitrust counterclaims to the Superior Court of New Jersey. The U.S. District Court also severed the parties’ patent law counterclaims and stayed those claims pending resolution of the action in the Central District of California. Mindray USA appealed the U.S. District Court’s remand order to the Court of Appeals for the Federal Circuit. On October 13, 2015, the Company filed a motion to dismiss Mindray USA’s appeal. The Company’s motion to dismiss and Mindray USA’s appeal remain pending before the Federal Circuit. On September 16, 2015, Shenzhen Mindray again removed the case to the U.S. District Court for the District of New Jersey. There is no guarantee that the Company will prevail in this suit or receive any damages or other relief if it does prevail.

In September 2012, a shareholder derivative lawsuit was filed in the U.S. District Court for the District of Delaware by Joseph Ausikaitis naming certain of the Company’s directors and certain executive officers as defendants and the Company as the nominal defendant. The lawsuit alleged claims of breach of fiduciary duty and unjust enrichment in connection with the grant or receipt of stock options under the Company’s 2007 Stock Incentive Plan and related policies. The lawsuit sought unspecified monetary damages on the Company’s behalf from the officer and director defendants, various forms of equitable and/or injunctive relief, attorneys’ and other professional fees and costs and various other forms of relief. On May 5, 2015, the plaintiff and the defendants entered into a Stipulation and Agreement of Settlement providing for an agreement to settle the lawsuit, which was approved by the Court on June 17, 2015. Pursuant to the Stipulation and Agreement of Settlement, the Company agreed to implement certain corporate governance measures and changes, and to ensure that such measures and changes remain in effect for at least 5 years. The Company is not required to pay, and will not receive, any monetary damages under the settlement.

In April 2011, the Company was informed by the United States Attorney’s Office for the Central District of California, Civil Division, that a qui tam complaint had been filed against the Company in the U.S. District Court for the Central District of California by three of the Company’s former physician office sales representatives. The qui tam complaint alleged, among other things, that the Company’s noninvasive hemoglobin products failed to meet their accuracy specifications, and that the Company misled the U.S. Food and Drug Administration (FDA) and customers regarding the accuracy of the products. In November 2011, the United States declined to intervene in the case, and in October 2013, the District Court granted summary judgment in favor of the Company. The former sales representatives have appealed the District Court’s decision.

In September 2011, two of the same former sales representatives filed employment-related claims against the Company in arbitration also stemming from their allegations regarding the Company’s noninvasive hemoglobin products. On January 16, 2014, the Company was notified that the arbitrator awarded the plaintiffs approximately $5.4 million in damages, which the Company accrued in fiscal 2013. In addition, the Company’s insurance carrier notified the Company that it believed certain defense costs related to the arbitration may no longer be reimbursable in view of the arbitration decision. As a result, the Company accrued a liability of $2.6 million in fiscal 2013 for the costs estimated to have been paid by the insurance carrier. The Company challenged the arbitration award in the U.S. District Court for the Central District of California, and on April 3, 2014, the District Court vacated the award. Accordingly, the Company reversed the $8.0 million charge in the quarter ended March 29, 2014. The former sales representatives have appealed the District Court’s decision. The Company is unable to predict the final outcome of the qui tam and employment matters. A reversal of the District Court’s decision in either matter could have a material adverse effect on the Company’s consolidated financial condition, results of operations or cash flows. The Company is unable to determine whether any loss will occur or to estimate the range of such loss; therefore, no amount of loss has been accrued by the Company as of the date of filing of this Quarterly Report on Form 10-Q.

In the third quarter of 2013, the Company was notified that the FDA and the United States Attorney’s Office for the Central District of California, Criminal Division (USAO), were investigating the allegations regarding its noninvasive hemoglobin products. In the second quarter of 2014, the Company received grand jury subpoenas requesting documents pertaining to, among other things, the testing, marketing and sales of its Pronto ^® and Pronto-7 ^® products. On May 7, 2015, the Company received a letter from the USAO stating that, at this time, the USAO has decided not to initiate any criminal charges against the Company or any of its current or former employees in connection with the investigation. The USAO reserved the right to revisit its decision at any time.

On January 2, 2014, a putative class action complaint was filed against the Company in the U.S. District Court for the Central District of California by Physicians Healthsource, Inc. The complaint alleges that the Company sent unsolicited facsimile advertisements in violation of the Junk Fax Protection Act of 2005 and related regulations. The complaint seeks $500 for each alleged violation, treble damages if the District Court finds the alleged violations to be knowing, plus interest, costs and injunctive relief. On April 14, 2014, the Company filed a motion to stay the case pending a decision on a related petition filed by the Company with the Federal Communications Commission (FCC). On May 22, 2014, the District Court granted the motion and stayed the case pending a ruling by the FCC on the petition. On October 30, 2014, the FCC granted some of the relief and denied some of the relief requested in the petition. Both parties appealed the FCC’s decision on the petition. On November 25, 2014, the District Court granted the parties’ joint request that the stay remain in place pending a decision on the appeal. The Company believes it has good and substantial defenses to the claims, but there is no guarantee that the Company will prevail. The Company is unable to determine whether any loss will occur or to estimate the range of such loss; therefore, no amount of loss has been accrued by the Company as of the date of filing of this Quarterly Report on Form 10-Q.

On January 31, 2014, an amended putative class action complaint was filed against the Company in the U.S. District Court for the Northern District of Alabama by and on behalf of two participants in the Surfactant, Positive Pressure, and Oxygenation Randomized Trial at the University of Alabama. On April 21, 2014, a further amended complaint was filed adding a third participant. The complaint alleges product liability and negligence claims in connection with pulse oximeters the Company modified and provided at the request of study investigators for use in the trial. A previous version of the complaint also alleged a wrongful death claim, which the Court dismissed on January 22, 2014. The amended complaint seeks unspecified damages, costs, interest, attorney fees and injunctive and other relief. On January 30, 2015, the Company filed a motion for summary judgment. On August 13, 2015, the Court granted summary judgment in favor of the Company, rejecting the plaintiffs’ claims. The plaintiffs have appealed the Court’s decision. The Company is unable to determine whether any loss will occur or to estimate the range of such loss; therefore, no amount of loss has been accrued by the Company as of the date of filing of this Quarterly Report on Form 10-Q.

On October 21, 2015, Medtronic plc (Medtronic) filed three separate inter partes review petitions (the Petitions) with the Patent Trial and Appeal Board (the PTAB) of the U.S. Patent and Trademark Office (PTO), challenging several of the claims of U.S. Patent Nos. 7,496,393 (the ’393 Patent), titled “Signal processing apparatus,” and 8,560,034 (the ’034 Patent), also titled “Signal processing apparatus,” which are owned by the Company. A patentability trial will commence if the PTAB decides to institute the inter partes review proceedings after considering the Petitions and the Company’s preliminary response to the Petitions. Medtronic has the right to stop paying royalties to the Company, subject to certain notice requirements, under the existing settlement agreement and has informed the Company that it will terminate the settlement covenants and stop paying royalties when it feels it has reached an appropriate point in the process. The Company intends to oppose the requests to institute proceedings relating to the Petitions, including on the basis that Medtronic is estopped from challenging the patentability of the ’034 patent, because the claims were previously the subject of an interference proceeding between the

Company and Medtronic’s subsidiary, Covidien plc, in which the PTO awarded the claimed subject matter to the Company. If the PTAB institutes the proceedings, the Company intends to defend the ’393 Patent and the ’034 Patent. The Company believes it has good and substantial responses to the Petitions, but there is no guarantee that the Company will prevail. The Company is unable to determine whether any loss will occur or to estimate the range of such loss; therefore, no amount of loss has been accrued by the Company as of the date of filing of this Quarterly Report on Form 10-Q.

From time to time, the Company may be involved in other litigation and investigations relating to claims and matters arising out of its operations in the normal course of business. The Company believes that it currently is not a party to any other legal proceedings which, individually or in the aggregate, would have a material adverse effect on its consolidated financial position, results of operations or cash flows.

14. Segment Information and Enterprise Reporting

The Company’s chief decision maker, the Chief Executive Officer, reviews financial information presented on a consolidated basis, accompanied by disaggregated information about revenues by geographic region, for purposes of making operating decisions and assessing financial performance. Accordingly, the Company considers itself to be in a single reporting segment, specifically noninvasive patient monitoring solutions and related products. The Company does not assess the performance of its geographic regions on other measures of income or expense, such as depreciation and amortization, operating income or net income including noncontrolling interest. In addition, the Company’s assets are primarily located in the U.S. The Company does not produce reports for, or measure the performance of, its geographic regions on any asset-based metrics. Therefore, geographic information is presented only for revenues.

The following schedule presents an analysis of the Company’s product revenues based upon the geographic area to which the product was shipped (in thousands, except percentages):

15. Income Taxes

The Company has provided for income taxes in fiscal 2015 interim periods based on the estimated effective income tax rate for the complete fiscal year. The income tax provision is computed on the estimated pretax income of the consolidated entities located within each taxing jurisdiction based on legislation enacted as of the balance sheet date. Deferred tax assets and liabilities are determined based on the future tax consequences associated with temporary differences between income and expenses reported for accounting and tax purposes. A valuation allowance for deferred tax assets is recorded to the extent that the Company cannot determine that the ultimate realization of the net deferred tax assets is more likely than not.

Realization of deferred tax assets is principally dependent upon the achievement of future taxable income, the estimation of which requires significant judgment by the Company’s management. The judgment of the Company’s management regarding future profitability may change due to many factors, including future market conditions and the Company’s ability to successfully execute its business plans or tax planning strategies. These changes, if any, may require material adjustments to these deferred tax asset balances. A valuation allowance has been previously recorded against all of the deferred tax assets of Cercacor. On a quarterly basis, Cercacor’s management reassesses the need for these valuation allowances based on operating results and its assessment of the likelihood of future taxable income and developments in the relevant tax jurisdictions. Cercacor continues to maintain a full valuation allowance as of October 3, 2015 against its net deferred tax assets.

As of October 3, 2015 , the liability for income taxes associated with uncertain tax positions was approximately $8.7 million . If fully recognized, approximately $7.1 million (net of federal benefit on state taxes) would impact the Company’s effective tax rate. The remaining balance relates to timing differences. It is reasonably possible that the amount of unrecognized tax benefits in various jurisdictions may change in the next twelve months due to the expiration of statutes of limitation and audit settlements. However, due to the uncertainty surrounding the timing of these events, an estimate of the change within the next twelve months cannot currently be made.

The Company conducts business in multiple jurisdictions and, as a result, one or more of the Company’s subsidiaries files income tax returns in U.S. federal, various state, local and foreign jurisdictions. The Company has concluded all U.S. federal income tax matters through fiscal year 2011. All material state, local and foreign income tax matters have been concluded through fiscal year 2007.

16. Subsequent Event

On November 4, 2015, the Company entered into an Amended and Restated Employment Agreement with Joe Kiani, Masimo’s Chairman and Chief Executive Officer (Restated Employment Agreement). The Restated Employment Agreement, among other things, eliminates the tax gross-up payments, “single trigger” change in control payments and certain survival provisions, as well as phases out the fixed annual stock option grants guaranteed to Mr. Kiani, under his previous employment agreement. Pursuant to the terms of the Restated Employment Agreement, upon a “Qualifying Termination” (as defined in the Restated Employment Agreement), Mr. Kiani will be entitled to receive a cash severance benefit equal to two times the sum of his then-current base salary and the average annual bonus paid to Mr. Kiani during the immediately preceding three years. In addition, upon a Qualifying Termination prior to 2018, Mr. Kiani will receive 2.7 million shares of common stock (subject to adjustment for recapitalizations, stock splits, stock dividends and the like) related to the vesting of certain restricted share units (RSUs) to be granted to Mr. Kiani in connection with the Restated Employment Agreement, and an additional cash payment of $35.0 million related to a Non-Competition and Confidentiality Agreement between Mr. Kiani and the Company (collectively, the Special Payment). For any Qualifying Termination occurring on or after January 1, 2018, the number of shares to be issued to Mr. Kiani pursuant to the restricted share units and the cash payment will each be reduced by 10% of the original amount each year so that after December 31, 2026, no Special Payment will be due. As of November 4, 2015, the estimated fair value of the Special Payment that would be recognized in the Company’s consolidated financial statements upon the occurrence of a Qualifying Termination, including the fair value of the common shares that would be issuable under the RSUs, approximated $146.9 million .

Executive Overview

We are a global medical technology company that develops, manufactures and markets a variety of noninvasive monitoring technologies. We provide our products directly and through distributors and OEM partners to hospitals, emergency medical service (EMS) providers, home care providers, physician offices, ambulatory surgery centers, long-term care facilities, veterinarians and consumers. Our mission is to improve patient outcomes and reduce the cost of care by taking noninvasive monitoring to new sites and applications. We were incorporated in California in May 1989 and reincorporated in Delaware in May 1996.

We invented Masimo Signal Extraction Technology ^® (Masimo SET ^® ) Measure-Through-Motion and Low-Perfusion ^™ pulse oximetry monitoring to address the primary limitations of conventional pulse oximetry. Pulse oximetry is the noninvasive measurement of the oxygen saturation level of arterial blood, which delivers oxygen to the body’s tissues, and pulse rate. Pulse oximetry is one of the most common measurements taken in and out of hospitals around the world. We believe that Masimo SET ^® is trusted by clinicians to safely monitor approximately 100 million patients each year. Masimo SET ^® pulse oximetry has been shown by more than 100 independent studies and thousands of clinical evaluations during patient motion and low-perfusion conditions to provide more accurate measurements than other non-Masimo pulse oximeters, as well as to significantly reduce false alarms (specificity), and accurately detect true alarms (sensitivity) that can indicate a deteriorating patient condition. The use of Masimo SET ^® pulse oximetry has also been shown to improve patient outcomes by helping clinicians reduce retinopathy of prematurity in neonates, screen newborns for critical congenital heart disease, reduce ventilator weaning time and arterial blood gas measurements in the intensive care unit (ICU), and save lives and costs while reducing rapid response activations and ICU transfers on the general floor.

Since introducing Masimo SET ^® , we have continued to innovate by introducing additional breakthrough noninvasive measurements that go beyond arterial blood oxygen saturation and pulse rate, and which create new market opportunities in both the hospital and non-hospital care settings. Our product offerings have expanded significantly over the years to include fluid responsiveness monitoring, noninvasive optical blood constituent monitoring, optical organ oximetry monitoring, electrical brain function monitoring, acoustic respiration monitoring and optical gas monitoring. In addition, we have developed the Root ^® patient monitoring and connectivity platform and Patient SafetyNet ^™ remote patient surveillance monitoring system.

Our Masimo rainbow ^® SET ^® platform leverages our Masimo SET ^® technology and incorporates licensed rainbow ^® technology to enable real-time monitoring of additional noninvasive measurements. Our rainbow ^® SET ^® platform includes our rainbow ^® SET ^® Pulse CO-Oximetry products, which we believe are the first devices cleared by the U.S. Food and Drug Administration (FDA) to noninvasively and continuously monitor multiple blood-based measurements using multiple wavelengths of light, which previously was only possible through intermittent invasive procedures. In addition to monitoring oxygen saturation (SpO ₂ ), pulse rate (PR), perfusion index (PI), Pleth Variability Index (PVI ^® ) and Respiration Rate (RRa ^™ ), Masimo rainbow ^® SET ^® Pulse CO-Oximetry has the ability to provide noninvasive monitoring of hemoglobin (SpHb ^® ), carboxyhemoglobin

Table of Contents

(SpCO ^® ) and methemoglobin (SpMet ^® ), as well as the calculation of Oxygen Content (SpOC ^® ). The Masimo rainbow ^® SET platform also allows for monitoring of arterial oxygen saturation, even under the presence of carboxyhemoglobin and methemoglobin, known as fractional arterial oxygen saturation (SpfO ₂ ^™ ), Respiration Rate from Pleth (RRp ^™ ) and Oxygen Reserve Index (ORI ^™ ). Although SpfO ₂ ^™ , RRp ^™ and ORI ^™ have received the CE Mark, they are not currently available for sale in the U.S.

Our O ₃ ^™ regional oximetry monitoring, also known as tissue oximetry and cerebral oximetry monitoring, uses near-infrared spectroscopy to provide for continuous measurement of tissue oxygen saturation (rSO ₂ ) to help detect regional hypoxemia that pulse oximetry alone can miss. In addition, our Root ^® patient monitor and O ₃ ^™ sensors can automate the differential analysis of regional to central oxygen saturation. O ₃ ^™ monitoring involves applying O ₃ ^™ regional oximetry sensors to the forehead and connecting our O ₃ ^™ Masimo Open Connect ^™ (MOC-9 ^™ ) module to any Root ^® monitor through one of its three MOC-9 ^™ ports. O ₃ ^™ regional oximetry is currently intended for use in subjects larger than 40 kg (approximately 88 lbs) and has received the CE Mark, but is not currently available for sale in the U.S.

Brain function monitoring is most commonly used during surgery to help clinicians avoid over-and under-titration of anesthesia and sedation. Our SedLine ^® brain function monitoring product measures the brain’s electrical activity by detecting electroencephalogram (EEG) signals. In contrast to whole scalp EEG monitoring, which is used for diagnostic purposes, this form of EEG monitoring is often referred to as processed EEG monitoring, or brain function monitoring. Brain function monitors display the patient’s EEG waveforms, but these are difficult for clinicians to interpret, so the EEG signals are processed and displayed as a single index that gives a continuous, quantitative indication of the patient’s depth of anesthesia and sedation. Our SedLine ^® brain function monitoring technology can now be delivered through the MOC-9 ^™ connectivity port within our Root ^® patient monitoring and connectivity platform that integrates our breakthrough rainbow ^® and SET ^® measurements with multiple additional parameters, such as SedLine ^® . In addition, our SedLine ^® brain function monitoring technology also displays raw EEG waveforms, the Patient State Index and the Density Spectral Array view.

Our sound-based monitoring technology, rainbow Acoustic Monitoring ^™ (RAM ^™ ), enables noninvasive monitoring of respiration rate (RRa ^® ). Compared to traditional capnography, which monitors exhaled carbon dioxide (CO ₂ ), most often through a nasal cannula, multiple clinical studies have shown that the noninvasive measurement of RRa ^® provides as good or better accuracy to monitor respiration rate and detect respiratory pause episodes, defined as a cessation of breathing for 30 seconds or more. When used with other clinical variables, RRa ^® may help clinicians assess respiratory depression and respiratory distress earlier and more often to help determine treatment options and potentially enable earlier interventions.

Our portfolio of capnography and gas monitoring products include external “plug-in-and-measure” capnography and gas analyzers, integrated modules and handheld capnograph and capnometer devices. These products have the ability to measure multiple expired gases, such as CO ₂ , nitrous oxide (N ₂ O), oxygen (O ₂ ) and other anesthetic agents. In the case of capnography, respiration rate is also calculated from the CO ₂ waveform. These measurements are possible through either mainstream monitoring, which samples gases from a ventilated patient’s breathing circuit, or sidestream monitoring, which samples gases from a breathing circuit in mechanically ventilated patients or through a cannula or mask in spontaneously breathing patients. In addition, our EMMA ^™ Capnograph with waveform display offers clinicians greater assessment of end-tidal CO ₂ and respiration rate, as well as assists in recognition of return to spontaneous circulation, for a variety of clinical settings, including emergency medicine and transport, operating rooms (ORs), ICUs, patient rooms and clinics. EMMA ^™ fits in the palm of the hand, and we believe it is the smallest and most portable capnograph in the world.

Root ^® is a powerful patient monitoring and connectivity platform that integrates our breakthrough rainbow ^® and SET ^® measurements with multiple additional specialty measurements through its MOC-9 ^™ connectivity ports in an integrated, clinician-centric platform. The first three Masimo MOC-9 ^™ technologies for Root ^® were SedLine ^® brain function monitoring, Phasein ^™ capnography and O ₃ ^™ regional oximetry. In addition, Iris ^™ connectivity in Root ^® enables third party devices such as intravenous pumps and ventilators to connect through Root ^® and enables display, notification and documentation to the electronic medical record through our Patient SafetyNet ^™ solution. In combination with a Radical-7 ^® handheld monitor, Root ^® will display alarm information simplifying patient care workflows and potentially helping caregivers make quicker patient assessments. Root ^® can also be connected with monitoring devices from other medical device companies that develop their own MOC-9 ^™ compatible modules.

Our patient surveillance, remote monitoring and clinician notification solution, Patient SafetyNet ^™ , allows for monitoring of the oxygen saturation, pulse rate, perfusion index, hemoglobin, methemoglobin and respiration rate of up to 200 patients simultaneously. Patient SafetyNet ^™ offers a rich user interface with trending, real-time waveform capability at the central station and remote notification via pager or smart phones. Patient SafetyNet ^™ also features the Adaptive Connectivity Engine ^™ , which enables two-way Health Level-7 (HL7) based connectivity to clinical/hospital information systems. The Adaptive Connectivity Engine ^™ significantly reduces the time and complexity to integrate and validate custom HL7 implementations, and

demonstrates our commitment to innovation that automates patient care with open, scalable and standards-based connectivity architecture.

In January 2015, we introduced our MightySat ^™ fingertip pulse oximeter for personal use. MightySat ^™ provides oxygen saturation and pulse rate measurements and is designed for those who want accurate measurements even under challenging conditions such as movement and low perfusion. MightySat ^™ is available in three versions, each of which provides SpO ₂ , PR and PI measurements in a compact, battery-powered design with a large color screen that can be rotated for real-time display of the pleth waveform as well as measurements. Optional Bluetooth wireless functionality enables measurement display via the free, downloadable Masimo Personal Health app on iOS and Android mobile devices, as well as the ability to trend and communicate measurements and interface with the Apple Health app. MightySat ^™ is also available with optional PVI ^® , a measure of the dynamic changes in the PI that occur during one or more complete respiratory cycles. MightySat ^™ is available through online retailers such as Amazon.com. In the U.S., MightySat ^™ is intended for general health and wellness use and is not intended for medical use. In June 2015, we announced the CE Mark and full market release of the MightySat ^™ Rx fingertip pulse oximeter for clinical use. In October 2015, we announced FDA 510(k) clearance for MightySat ^™ Rx.

In April 2015, we introduced the Patient SafetyNet Series 5000 ^™ along with Iris ^™ Connectivity and MyView ^™ through the Root ^® patient monitoring and connectivity platform. This series of Patient SafetyNet ^™ offers a new level of interoperability designed to enhance clinician workflows, and reduce the cost of care, from operating rooms to medical-surgical units. The Patient SafetyNet Series 5000 ^™ with Iris ^™ enables Root ^® to intake data from all devices connected to the patient, acting as an in-room patient monitor and connectivity hub. Alarms and alerts for all devices are seamlessly forwarded to the patient’s clinician and all device data are effortlessly documented in the patient’s electronic medical record (EMR). The patient-centric user interface of Patient SafetyNet Series 5000 ^™ displays near real-time data from all devices, providing a single unified dashboard of patient information. Having such a holistic view can enable caregivers to more quickly assess patient status, allowing for faster clinical decisions. To simplify documentation of patient data, Root ^® enables clinicians to easily verify and send patient vitals, as well as all connected medical device information data, to the EMR directly from Root ^® . Data can also be sent to the EMR periodically. An interface between the Patient SafetyNet Series 5000 ^™ Appliance and the hospital admission, discharge and transfer (ADT) system allows clinicians to receive ADT information on Root ^® for positive patient identification at the bedside. Clinicians can also manually enter additional data on the Root ^® device, including temperature, blood pressure, level of consciousness, pain score and urine output.

MyView ^™ is a wireless, presence-detection system that enables clinicians to automatically display customized clinical profiles on our devices, such as Root ^® , Radical-7 ^® and the Patient SafetyNet View Station. When a clinician approaches the device, a clinician-worn MyView ^™ badge signals the device to display a preselected set of parameters and waveforms tailored to the individual clinician’s preferences. MyView ^™ gives clinicians the ability to receive and review medical device information in a manner that is most conducive to optimizing their workflow, while the presence mapping data collected by all the Masimo devices can provide information on how clinicians spend time with their patients. This provides nursing leadership and management with the opportunity to examine analytical data on patient and clinician interactions to optimize workflows across the unit, hospital or hospital system.

In June 2015, we announced the CE Mark and pre-market release of noninvasive blood pressure and temperature capabilities for our Root ^® connectivity and patient monitoring platform. Root ^® with noninvasive blood pressure from SunTech Medical ^® enables clinicians to measure arterial blood pressure for adult, pediatric and neonatal patients, with three distinct measurement modes: spot-check, automatic interval and stat interval. The temperature module from Welch Allyn ^® can measure the temperature of adult, pediatric and neonatal patients.

Our pulse oximetry technology is generally contained on a circuit board that is placed inside a standalone pulse oximetry monitor, placed inside OEM multi-parameter monitors or included as part of an external “Board-in-Cable” solution that is plugged into a port on an OEM or other device. All of these solutions use our proprietary single-patient use sensors, reusable sensors and/or cables. We sell our products to end-users through our direct sales force and certain distributors, as well as our OEM partners, for incorporation into their products. We also sell certain pulse oximetry products in the consumer market for non-medical use.

Since inception, our mission has been to develop noninvasive monitoring solutions that improve patient outcomes and reduce the cost of patient care. We intend to continue to grow our business and improve our market position by pursuing the following strategies:


(1)	continue to expand our market share in pulse oximetry;


(2)	expand the pulse oximetry market to other patient care settings;


(3)	expand the use of rainbow ^® technology in hospital settings;


(4)	expand the use of rainbow ^® technology in non-hospital settings, including EMS providers and physician offices;

Table of Contents


(5)	utilize our customer base and OEM relationships to market our Masimo rainbow ^® SET ^® products incorporating licensed rainbow ^® technology as well as our other noninvasive specialty monitoring products including capnography, gas, brain function and regional oximetry monitoring; and


(6)	continue to innovate and maintain our technology leadership position.

Our solutions and related products are based upon our Masimo SET ^® , rainbow ^® and other proprietary algorithms. This software-based technology is incorporated into a variety of product platforms depending on our customers’ specifications.

Product revenue increased $7.5 million , or 5.4% , to $144.6 million for the three months ended October 3, 2015 from $137.1 million for the three months ended September 27, 2014 . This increase was primarily due to stronger sales of consumable products, monitors and parameter licenses. This increase in sales was partially offset by the impact of approximately $4.8 million related to unfavorable movements in foreign exchange rates from the prior year period that reduced the U.S. Dollar translation of foreign sales that were denominated in various foreign currencies, primarily in Europe and Asia. We estimate that our installed base of circuit boards and pulse oximeters increased to 1,390,000 units at October 3, 2015 as compared to 1,289,000 units at September 27, 2014 .

Product revenue generated through our direct and distribution sales channels increased $4.1 million , or 3.5% , to $120.2 million for the three months ended October 3, 2015 , compared to $116.1 million for the three months ended September 27, 2014 . During the three months ended October 3, 2015 , revenues from our OEM channel increased by $3.4 million , or 16.0% , to $24.4 million from $21.0 million for the three months ended September 27, 2014 . Total rainbow ^® product revenue increased to $17.1 million for the three months ended October 3, 2015 , compared to $13.2 million for the three months ended September 27, 2014 .

Royalty revenue consists of amounts received from Medtronic plc (Medtronic, formerly Covidien) related to their U.S. sales pursuant to the terms of our amended settlement agreement. Based on the terms of such agreement, Medtronic has the right to stop paying us royalties, subject to certain notice requirements. On October 21, 2015, Medtronic filed three separate inter partes review petitions with the Patent Trial and Appeal Board of the U.S. Patent and Trademark Office, challenging several of the claims of two U.S. patents titled “Signal processing apparatus” that are owned by us. Medtronic has informed us that it will terminate the covenants they received from us under the settlement agreement and stop paying royalties when it feels it has reached an appropriate point in the process. See Note 13 to the condensed consolidated financial statements under the caption “Litigation” included in Part I, Item 1 and “Medtronic may seek to avoid paying any royalties to us, which would significantly reduce our royalty revenues and adversely affect our business, financial condition and results of operations” under Part II, Item 1A - Risk Factors, in this Quarterly Report on Form 10-Q for additional information.

Gross Profit. Gross profit consists of total revenue less cost of goods sold. Our gross profit for the three months ended October 3, 2015 and September 27, 2014 was as follows (dollars in thousands):



	Three Months Ended
	October 3, 2015		Percentage of Revenue		September 27, 2014		Percentage of Revenue		Increase/ (Decrease)		Percentage Change
Product Gross Profit	$	94,260	65.2	%	$	89,248	65.1	%	$	5,012	5.6	%
Royalty Gross Profit	7,972		100.0		6,976		100.0		996		14.3
Total Gross Profit	$	102,232	67.0	%	$	96,224	66.8	%	$	6,008	6.2	%

Cost of goods sold includes labor, material, overhead and other similar costs related to the production, supply, distribution and support of our products. Cost of goods sold increased $2.4 million for the three months ended October 3, 2015 compared to the three months ended September 27, 2014 , due primarily to the increase in our product revenues. Our total gross margins increased slightly to 67.0% for the three months ended October 3, 2015 as compared to 66.8% for the three months ended September 27, 2014 . Excluding royalties, our product gross margin also slightly increased slightly to 65.2% for the three months ended October 3, 2015 as compared to 65.1% for the three months ended September 27, 2014 . This net increase in product gross margin was primarily due to the benefits from our continued product cost reduction efforts, which were partially offset by the net impact of unfavorable movements in foreign exchange rates from the prior year period. We incurred $1.7 million and $0.9 million in Cercacor royalty expenses for the three months ended October 3, 2015 and September 27, 2014 , respectively, which have been eliminated in our condensed consolidated financial statements for the periods presented. Had these royalty expenses not been eliminated, our reported product gross profit margin would have been 64.0% for the three months ended October 3, 2015 and 64.4% for the three months ended September 27, 2014 .

Selling, General and Administrative. Selling, general and administrative expenses consist primarily of salaries and related expenses for sales, marketing and administrative personnel, sales commissions, advertising and promotion costs, professional fees related to legal, accounting and other outside services, public company costs, medical device taxes and other corporate expenses. Selling, general and administrative expenses for the three months ended October 3, 2015 and September 27, 2014 were as follows (dollars in thousands):

$59,607	39.1%	$62,064	43.1%	$(2,457)	(4.0)%

Table of Contents

Selling, general and administrative expenses decreased $2.5 million , or 4.0% , for the three months ended October 3, 2015 compared to the three months ended September 27, 2014 . This decrease was primarily attributable to lower legal and professional fees of approximately $3.5 million and lower payroll related costs of $0.9 million, which were partially offset by higher charitable donations of approximately $1.6 million, including $0.8 million of donations related to the Masimo Foundation for Ethics, Innovation and Competition in Healthcare (the Masimo Foundation) and $0.6 million to Jordanian hospitals to help improve patient care for Syrian and Iraqi refugees, in the current year period. Share-based compensation expense of approximately $2.0 million and $2.2 million was included in selling, general and administrative expenses for the three months ended October 3, 2015 and September 27, 2014 , respectively. Approximately $1.5 million and $1.8 million of medical device excise tax was included in selling, general and administrative expenses for the three months ended October 3, 2015 and September 27, 2014 , respectively. Also included in total selling, general and administrative expenses were $0.6 million and $0.7 million of expenses incurred by Cercacor for the three months ended October 3, 2015 and September 27, 2014 , respectively.

In July 2014, an arbitration panel issued a final award of $4.0 million to Cercacor, our VIE, in connection with the breach by a third party of a supply agreement, payment for which was received by Cercacor in August 2014. Cercacor recorded this award in the quarter ended September 27, 2014 as a reduction to operating expenses, net of approximately $1.6 million in related legal costs. We did not record any similar litigation award during the three months ended October 3, 2015 .

Non-operating income. Non-operating income consists primarily of interest income, interest expense and foreign exchange losses. Non-operating income for the three months ended October 3, 2015 and September 27, 2014 was as follows (dollars in thousands):



Non-operating Income (Expense)
Three Months Ended October 3, 2015	Percentage of Net Revenues	Three Months Ended September 27, 2014	Percentage of Net Revenues	Increase/ (Decrease)	Percentage Change
$(1,050)	(0.7)%	$(566)	(0.4)%	$(484)	85.5%

Non-operating income (expense) increased by $0.5 million for the three months ended October 3, 2015 compared to the three months ended September 27, 2014 . Non-operating expense of $1.1 million for the three months ended October 3, 2015 consisted of $0.6 million of interest expense and $0.5 million of net realized and unrealized losses on foreign currency denominated transactions.

Provision for Income Taxes. Our provision for income taxes for the three months ended October 3, 2015 and September 27, 2014 was as follows (dollars in thousands):



Provision for Income Taxes
Three Months Ended October 3, 2015	Percentage of Net Revenues	Three Months Ended September 27, 2014	Percentage of Net Revenues	Increase/ (Decrease)	Percentage Change
$9,161	6.0%	$5,568	3.9%	$3,593	64.5%

Our provision for income taxes was $9.2 million , or an effective tax rate of 33.8%, for the three months ended October 3, 2015 , compared to $5.6 million , or an effective tax rate of 25.7%, for the three months ended September 27, 2014 . The higher effective tax rate for the three months ended October 3, 2015 is due to a shift in the expected fiscal 2015 geographic composition of our pre-tax income to higher taxed jurisdictions resulting primarily from increased fiscal 2015 U.S. revenues and unfavorable year over year movements in foreign exchange rates that generally reduced international revenues that are denominated in foreign currencies.

Comparison of the Nine Months ended October 3, 2015 to the Nine Months ended September 27, 2014

Revenue . Total revenue increased $38.0 million , or 8.9% , to $462.8 million for the nine months ended October 3, 2015 from $424.9 million for the nine months ended September 27, 2014 . The following chart details our total product revenues by the geographic area to which the products were shipped for the nine months ended October 3, 2015 and September 27, 2014 (dollars in thousands):

Total Revenue	$	462,838			$	424,856			$	37,982

Product revenue increased $36.7 million , or 9.1% , to $439.6 million for the nine months ended October 3, 2015 from $402.9 million for the nine months ended September 27, 2014 . This increase was primarily due to higher consumable product sales. Offsetting this increase in sales was the impact of approximately $14.5 million related to unfavorable movements in foreign exchange rates from the prior year period that reduced the U.S. Dollar translation of foreign sales that were denominated in various foreign currencies, primarily in Europe and Asia. We estimate that our installed base of circuit boards and pulse oximeters increased to 1,390,000 units at October 3, 2015 as compared to 1,289,000 units at September 27, 2014 .

Product revenue generated through our direct and distribution sales channels increased $29.8 million , or 8.8% , to $370.4 million for the nine months ended October 3, 2015 , compared to $340.5 million for the nine months ended September 27, 2014 . During the nine months ended October 3, 2015 , revenues from our OEM channel increased by $6.9 million , or 11.1% , to $69.2 million from $62.3 million for the nine months ended September 27, 2014 . Total rainbow ^® product revenue increased to $42.7 million for the nine months ended October 3, 2015 , compared to $37.6 million for the nine months ended September 27, 2014 .

Royalty revenue consists of amounts received from Medtronic related to their U.S. sales pursuant to the terms of our amended settlement agreement. Based on the terms of such agreement, Medtronic has the right to stop paying us royalties, subject to certain notice requirements. On October 21, 2015, Medtronic filed three separate inter partes review petitions with the Patent Trial and Appeal Board of the U.S. Patent and Trademark Office, challenging several of the claims of two U.S. patents titled “Signal processing apparatus” that are owned by us. Medtronic has informed us that it will terminate the covenants it received from us under the settlement agreement and stop paying royalties when it feels it has reached an appropriate point in the process. See Note 13 to the condensed consolidated financial statements under the caption “Litigation” included in Part I, Item 1 and “Medtronic may seek to avoid paying any royalties to us, which would significantly reduce our royalty revenues and adversely affect our business, financial condition and results of operations” under Part II, Item 1A - Risk Factors, in this Quarterly Report on Form 10-Q for additional information.

Gross Profit. Gross profit consists of total revenue less cost of goods sold. Our gross profit for the nine months ended October 3, 2015 and September 27, 2014 was as follows (dollars in thousands):



	Nine Months Ended
	October 3, 2015		Percentage of Revenue		September 27, 2014		Percentage of Revenue		Increase/ (Decrease)		Percentage Change
Product Gross Profit	$	284,972	64.8	%	$	259,632	64.4	%	$	25,340	9.8	%
Royalty Gross Profit	23,266		100.0		21,988		100.0		1,278		5.8
Total Gross Profit	$	308,238	66.6	%	$	281,620	66.3	%	$	26,618	6.2	%

Cost of goods sold increased $11.4 million for the nine months ended October 3, 2015 compared to the nine months ended September 27, 2014 due primarily to the increase in product revenue. Our total gross margin increased to 66.6% for the nine months ended October 3, 2015 from 66.3% for the nine months ended September 27, 2014 . Excluding royalties, product gross margin increased to 64.8% for the nine months ended October 3, 2015 from 64.4% for the nine months ended September 27, 2014 . This net increase in product gross margin was primarily due to the benefits from our continued product cost reduction efforts, which were partially offset by the net impact of unfavorable movements in foreign exchange rates from the prior year period. We incurred $4.3 million and $4.0 million in Cercacor royalty expenses for the nine months ended October 3, 2015 and September 27, 2014 , respectively, which have been eliminated in our condensed consolidated financial statements for the periods presented. Had these royalty expenses not been eliminated, our reported product gross profit margin would have been 63.7% for the nine months ended October 3, 2015 and 63.4% for the nine months ended September 27, 2014 .

Selling, General and Administrative. Selling, general and administrative expenses for the nine months ended October 3, 2015 and September 27, 2014 were as follows (dollars in thousands):



Selling, General and Administrative
Nine Months Ended October 3, 2015	Percentage of Net Revenues	Nine Months Ended September 27, 2014	Percentage of Net Revenues	Increase/ (Decrease)	Percentage Change
$182,072	39.3%	$179,533	42.3%	$2,539	1.4%

Selling, general and administrative expenses increased $2.5 million , or 1.4% , for the nine months ended October 3, 2015 compared to the nine months ended September 27, 2014 . This increase was primarily attributable to higher occupancy costs of $1.4 million, higher legal and professional fees of approximately $0.7 million, higher payroll related costs of $0.6 million and higher marketing related expenses of $0.4 million, which were partially offset by approximately $0.8 million in lower charitable donations, including $1.3 million of lower donations to the Masimo Foundation and $0.5 million of lower donations to the Patient Safety Movement Foundation. Share-based compensation expense of approximately $6.1 million and $6.3 million was included in selling, general and administrative expenses for the nine months ended October 3, 2015 and September 27, 2014 , respectively. Approximately $5.1 million and $5.0 million of medical device excise tax was included in selling, general and administrative expenses for the nine months ended October 3, 2015 and September 27, 2014 , respectively. Also included in total selling, general and administrative expenses were $2.0 million and $2.4 million of direct expenses incurred by Cercacor for the nine months ended October 3, 2015 and September 27, 2014 , respectively.

Research and Development. Research and development expenses for the nine months ended October 3, 2015 and September 27, 2014 were as follows (dollars in thousands):



Research and Development
Nine Months Ended October 3, 2015	Percentage of Net Revenues	Nine Months Ended September 27, 2014	Percentage of Net Revenues	Increase/ (Decrease)	Percentage Change
$42,808	9.2%	$41,552	9.8%	$1,256	3.0%

Research and development expenses increased by $1.3 million , or 3.0% , for the nine months ended October 3, 2015 compared to the nine months ended September 27, 2014 . This increase was primarily due to higher payroll related costs of approximately $1.4 million and higher engineering project and supply costs of $0.3 million, which were partially offset by lower occupancy-related costs of $0.4 million. Included in research and development expenses was approximately $1.8 million and $1.1 million of share-based compensation expense for the nine months ended October 3, 2015 and September 27, 2014 , respectively. Also included in total research and development expenses were $5.2 million and $2.6 million of engineering expenses incurred by Cercacor for the nine months ended October 3, 2015 and September 27, 2014 , respectively.

Litigation Award and Defense Costs. Litigation award and defense costs for the nine months ended October 3, 2015 and September 27, 2014 were as follows (dollars in thousands):



Litigation Award and Defense Costs
Nine Months Ended October 3, 2015	Percentage of Net Revenues	Nine Months Ended September 27, 2014	Percentage of Net Revenues	Increase/ (Decrease)	Percentage Change
$—	—%	$(10,331)	(2.4)%	$10,331	—%

Two of our former physician office sales representatives filed employment-related claims against us in 2011 regarding our noninvasive hemoglobin monitoring products. In January 2014, an arbitrator awarded the plaintiffs approximately $5.4 million in damages. As a result of this award, we recorded a charge of $8.0 million in the fiscal quarter ended December 28, 2013, which included $5.4 million in damages and $2.6 million in defense-related costs. We challenged the award in the U.S. District Court for the Central District of California, and in April 2014, the District Court vacated the award. Accordingly, we reversed the previous $8.0 million charge in the fiscal quarter ended March 29, 2014. We did not record any similar reversal during the nine months ended October 3, 2015 .

Non-operating income. Non-operating income consists primarily of interest income, interest expense and foreign exchange losses. Non-operating income for the nine months ended October 3, 2015 and September 27, 2014 was as follows (dollars in thousands):



Non-operating Income
Nine Months Ended October 3, 2015	Percentage of Net Revenues	Nine Months Ended September 27, 2014	Percentage of Net Revenues	Increase/ (Decrease)	Percentage Change
$(2,022)	(0.4)%	$(43)	—%	$(1,979)	4,602.3%

Non-operating expense increased by approximately $2.0 million for the nine months ended October 3, 2015 as compared to non-operating expense of less than $0.1 million for the nine months ended September 27, 2014 . Non-operating expense for the nine months ended October 3, 2015 consisted of $1.6 million of interest expense and $0.4 million of net realized and unrealized losses on foreign currency denominated transactions. Non-operating expense for the nine months ended September 27, 2014 consisted of $0.2 million of interest expense and $0.1 million of net realized and unrealized gains on foreign currency denominated transactions.

Provision for Income Taxes. Our provision for income taxes for the nine months ended October 3, 2015 and September 27, 2014 was as follows (dollars in thousands):



Provision for Income Taxes
Nine Months Ended October 3, 2015	Percentage of Net Revenues	Nine Months Ended September 27, 2014	Percentage of Net Revenues	Increase/ (Decrease)	Percentage Change
$24,889	5.4%	$18,246	4.3%	$6,643	36.4%

Our provision for income taxes was $24.9 million , or an effective tax rate of 30.6%, for the nine months ended October 3, 2015 , compared to $18.2 million , or an effective tax rate of 25.8%, for the nine months ended September 27, 2014 . The higher effective tax rate for the nine months ended October 3, 2015 is due to a shift in the expected fiscal 2015 geographic composition of our pre-tax income to higher taxed jurisdictions resulting primarily from increased fiscal 2015 U.S. revenues and unfavorable year over year movements in foreign exchange rates that generally reduced international revenues that are denominated in foreign currencies.

Liquidity and Capital Resources

Our principal sources of liquidity consist of our existing cash and cash equivalent balances, funds expected to be generated from operations and funds available under our revolving credit agreement. At October 3, 2015 , we had approximately $185.8 million in working capital and approximately $103.6 million in cash and cash equivalents as compared to approximately $191.2 million in working capital and approximately $134.5 million in cash and cash equivalents at January 3, 2015 . We currently do not maintain an investment portfolio but have the ability to invest in various security holdings, types and maturities that meet credit quality standards in accordance with our investment guidelines.

Table of Contents

As of October 3, 2015 , we had cash totaling $71.8 million held outside of the U.S., of which approximately $12.4 million was accessible without additional tax cost and approximately $59.4 million was accessible at an incremental estimated tax cost of approximately $17.9 million . In managing our day-to-day liquidity and capital structure, we do not rely on foreign earnings as a source of funds. We currently have sufficient funds on-hand and available under our line of credit to fund our domestic operations and do not anticipate the need to repatriate funds associated with our permanently reinvested foreign earnings. In the event funds that are treated as permanently reinvested are repatriated, we may be required to accrue and pay additional U.S. taxes with respect to any such repatriation.

Our existing credit agreement with JPMorgan Chase Bank, N.A., as Administrative Agent and a Lender, and Bank of America, N.A., as a Lender (our Amended Credit Agreement) currently provides aggregate borrowing capacity of up to $250.0 million with an option, subject to certain conditions, to increase the aggregate borrowing capacity up to $350.0 million in the future. All unpaid principal under the Amended Credit Agreement will become due and payable on September 29, 2019. See Note 10 to the condensed consolidated financial statements included in this Quarterly Report on Form 10-Q for additional information.

During the three months ended October 3, 2015 , we received $8.0 million from Medtronic for royalties related to their U.S. sales pursuant to the terms of our amended settlement agreement. Based on the terms of such agreement, Medtronic has the right to stop paying us royalties, subject to certain notice requirements. On October 21, 2015, Medtronic filed three separate inter partes review petitions with the Patent Trial and Appeal Board of the U.S. Patent and Trademark Office, challenging several of the claims of two U.S. patents titled “Signal processing apparatus” that are owned by us. Medtronic has informed us that it will terminate the covenants they received from us under the settlement agreement and stop paying royalties when it feels it has reached an appropriate point in the process. See Note 13 to the condensed consolidated financial statements under the caption “Litigation” included in Part I, Item 1and “Medtronic may seek to avoid paying any royalties to us, which would significantly reduce our royalty revenues and adversely affect our business, financial condition and results of operations” under Part II, Item 1A - Risk Factors, in this Quarterly Report on Form 10-Q for additional information.

Cash Flows



The following table summarizes our cash flows (in thousands):
	Nine Months Ended
	October 3, 2015			September 27, 2014
Net cash provided by (used in):
Operating activities	$	53,495		$	66,823
Investing activities	(43,605		)	(69,626		)
Financing activities	(38,927		)	28,651
Effect of foreign currency exchange rates on cash	(1,835		)	(2,326		)
(Decrease) increase in cash and cash equivalents	$	(30,872	)	$	23,522

Operating Activities. Cash provided by operating activities was $53.5 million in the nine months ended October 3, 2015 , arising primarily from net income of $56.4 million , non-cash activity for depreciation and amortization of $11.6 million and share-based compensation of $8.1 million . Other changes in operating assets and liabilities included a decrease in accounts payable of $4.2 million , an increase in prepaid income taxes of $5.0 million , a decrease in accrued compensation of $1.4 million and a decrease in income taxes payable of $2.2 million , all due to the timing of related payments; an increase in other assets of $4.1 million due primarily to an increase in prepaid discounts; and an increase in accounts receivable of $5.0 million due to the timing of collections.

Cash provided by operating activities was $66.8 million for the nine months ended September 27, 2014 , arising primarily from net income of $52.6 million , non-cash activity for depreciation and amortization of $9.5 million , share-based compensation of $7.8 million and a provision for deferred taxes of $2.9 million . In addition, accounts payable decreased by $1.6 million and prepaid income taxes increased by $0.7 million , both due to the timing of payments; and accounts receivable decreased by $3.2 million due to the timing of cash receipts from customers. These sources of cash were primarily offset by an increase in accrued compensation and accrued liabilities of $1.2 million and $5.4 million , respectively, due to the timing of payments.

Investing Activities . Cash used in investing activities for the nine months ended October 3, 2015 was $43.6 million , consisting primarily of $40.5 million for purchases of property and equipment, including $6.3 million related to the purchase of our New Hampshire manufacturing and warehouse facility (New Hampshire Property), and $3.1 million of intangible assets, of which approximately $2.2 million related to capitalized patent and trademark costs and approximately $0.9 million related to intangible assets acquired in connection with the purchase of our New Hampshire Property.

Table of Contents

Cash used in investing activities for the nine months ended September 27, 2014 was $69.6 million , consisting of $66.8 million , for purchases of property and equipment, including $57.8 million related to the purchase of our new corporate headquarters, and $2.8 million for the increase in intangible assets related to capitalized patent and trademark costs.

Financing Activities . Cash used in financing activities for the nine months ended October 3, 2015 was $38.9 million , primarily resulting from common stock repurchase transactions that settled during the quarter totaling $130.2 million , offset by net borrowings under our Amended Credit Agreement of $65.0 million and proceeds from the issuance of common stock (upon exercise of options) totaling $24.9 million .

Cash provided by financing activities for the nine months ended September 27, 2014 was $28.7 million , primarily resulting from borrowings under our line of credit totaling $125.0 million , offset by common stock repurchase transactions totaling $98.7 million .

Capital Resources and Prospective Capital Requirements

As of October 3, 2015 , we had $190.0 million in outstanding loan draws under our Amended Credit Agreement, leaving available borrowing capacity of $60.0 million . We also had outstanding capital lease obligations of $0.2 million related primarily to office and computer equipment. We had no other debt obligations and are in compliance with all bank covenants.

In February 2013, our board of directors (Board) authorized the repurchase of up to 6.0 million shares of our common stock under a repurchase program. In October 2014, the Board authorized us to repurchase up to an additional 3.0 million shares under this stock repurchase program. During the three months ended October 3, 2015 , approximately 1.2 million shares were repurchased at an average cost of $41.44 per share. As of October 3, 2015 , all of the authorized 9.0 million shares had been repurchased under this stock repurchase program.

In September 2015, our Board authorized a new stock repurchase program for the repurchase of up to 5.0 million shares. As of October 3, 2015 , no shares had been repurchased under this program. For additional information regarding our stock repurchase program, see Note 11 to the condensed consolidated financial statements included in this Quarterly Report on Form 10-Q.

We expect to fund our future operating, investing and financing activities through our available cash, future cash from operations, funds available under our Amended Credit Agreement and other potential sources of capital. In addition to funding our normal working capital requirements, we anticipate additional capital purchases related to renovating our new corporate headquarters. We also anticipate that we will continue to repurchase stock under our authorized stock repurchase program subject to the availability of our stock, general market conditions, the trading price of our stock, available capital, alternative uses for capital and our financial performance. Possible additional uses of cash may include the acquisition of technologies or technology companies. The amount and timing of our actual investing activities will vary significantly depending on numerous factors, including the timing and amount of costs related to the renovation of our new corporate headquarters facility and other capital expenditures, costs of product development efforts, stock repurchase activity and costs related to our domestic and international regulatory requirements. Despite these investment requirements, we anticipate that our existing cash and cash equivalents, as well as amounts available under the Amended Credit Agreement, will be sufficient to meet our working capital requirements, capital expenditures and other operational funding needs for at least the next 12 months.

Off-Balance Sheet Arrangements

We do not currently have, nor have we ever had, any relationships with unconsolidated entities or financial partnerships, such as entities referred to as structured finance or special purpose entities, which would have been established for the purpose of facilitating off-balance sheet arrangements or for other contractually narrow or limited purposes. In addition, we do not engage in trading activities involving non-exchange traded contracts. As a result, we are not materially exposed to any financing, liquidity, market or credit risk that could arise if we engaged in these relationships. As of October 3, 2015 , we did not have any off-balance sheet arrangements, as defined in Item 303(a)(4)(ii) of Regulation S-K promulgated by the SEC.

Critical Accounting Policies and Estimates

The discussion and analysis of our financial condition and results of operations is based on our condensed consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of these condensed consolidated financial statements requires management to make estimates and judgments that affect the reported amounts of net revenues, expenses, assets and liabilities. We regularly evaluate our estimates and assumptions related to our critical accounting policies, including revenue recognition and deferred revenue, inventory and related reserves for excess or obsolete inventory, allowance for doubtful accounts, share-based compensation, goodwill, deferred taxes and related valuation allowances, uncertain tax positions, tax contingencies, litigation costs and loss

Table of Contents

contingencies. We base our estimates and assumptions on current facts, historical experience and various other factors that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities and the recording of revenue, costs and expenses that are not readily apparent from other sources. Changes in judgments and uncertainties relating to these estimates could potentially result in materially different results under different assumptions and conditions. If these estimates differ significantly from actual results, the impact on our condensed consolidated financial statements and future results of operations may be material. For a description of our critical accounting policies, please refer to “Critical Accounting Estimates” in Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” of our Annual Report on Form 10-K for the fiscal year ended January 3, 2015 filed with the SEC on February 17, 2015. There have been no material changes to any of our critical accounting policies during the nine months ended October 3, 2015 .

Recent Accounting Pronouncements

See Note 2 to the condensed consolidated financial statements included in this Quarterly Report on Form 10-Q for a description of recently issued or adopted accounting standards.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Market risk represents the risk of changes in the value of market risk sensitive instruments caused by fluctuations in interest rates, foreign exchange rates and commodity prices. We are exposed to various market risks that may arise from adverse changes in market rates and prices, such as interest rates, foreign exchange fluctuations and inflation. We do not enter into derivatives, including forward contracts, or other financial instruments for trading or speculative purposes.

Interest Rate Risk

Our exposure to market risk for changes in interest rates relates to the increase or decrease in the amount of interest income we can earn on our investment portfolio and on the increase or decrease in the amount of interest expense we must pay with respect to our various outstanding debt instruments. Our risk associated with fluctuations in interest expense is limited to interest associated with our outstanding capital lease arrangements, which have fixed interest rates, and any borrowings under our Amended Credit Agreement and any amendments thereto. Under our current policies, we do not use interest rate derivative instruments to manage exposure to interest rate changes. We ensure the safety and preservation of our invested principal funds by limiting default risk, market risk and reinvestment risk. We reduce default risk by investing in investment grade securities. A hypothetical 100 basis point change in interest rates along the entire interest rate yield curve would not significantly affect the fair value of our interest-sensitive financial instruments at October 3, 2015 . Declines in interest rates over time will, however, reduce our interest income and expense while increases in interest rates will increase our interest income and expense.

Foreign Currency Exchange Rate Risk

A majority of our assets and liabilities are maintained in the United States in U.S. Dollars and a majority of our sales and expenditures are transacted in U.S. Dollars. However, we also transact with foreign customers in currencies other than the U.S. Dollar. These foreign currency revenues, when converted into U.S. Dollars, can vary depending on average exchange rates during a respective period. In addition, certain of our foreign subsidiaries transact in their respective country’s local currency, which is also their functional currency. As a result, expenses of these foreign subsidiaries, when converted into U.S. Dollars, can vary depending on the average exchange rates during a respective period.

We are exposed to foreign currency gains or losses on outstanding foreign currency denominated receivables and payables, as well as intercompany transactions. Realized and unrealized foreign currency gains or losses on these transactions are included in our statements of comprehensive income as incurred. Furthermore, other transactions between us or our subsidiaries and a third-party, denominated in a currency different from the functional currency, are foreign currency transactions. Realized and unrealized foreign currency gains or losses on these transactions are included in our statements of comprehensive income as incurred, and are converted to U.S. Dollars at the average exchange rates for a respective period.

The balance sheets of each of our foreign subsidiaries whose functional currency is not the U.S. Dollar are translated into U.S. Dollars at the rate of exchange at the balance sheet date and the statements of comprehensive income and cash flows are translated into U.S. Dollars using the average monthly exchange rate during the period. Any foreign exchange gain or loss as a result of translating the balance sheets of our foreign subsidiaries whose functional currency is not the U.S. Dollar is included in equity as a component of accumulated other comprehensive income.

Our primary foreign currency exchange rate exposures are with the Euro, Japanese Yen, Swedish Krona, Canadian Dollar, British Pound, Mexican Peso and Australian Dollar, against the U.S. Dollar. Foreign currency exchange rates have experienced significant movements recently, particularly when compared to the same prior year period, and such volatility may continue in the future. Specifically, during the three and nine months ended October 3, 2015 , we estimate that changes in the exchange

Table of Contents

rates of the U.S. Dollar relative primarily to the Euro, Japanese Yen, Swedish Krona, Canadian Dollar, British Pound and Australian Dollar, negatively impacted our revenues by $4.8 million and $14.5 million , respectively, when compared to foreign exchange rates from the prior year periods. We currently do not enter into forward exchange contracts to hedge exposures denominated in foreign currencies and do not use derivative financial instruments for trading or speculative purposes. The effect of a 10% change in foreign currency exchange rates could have a material effect on our future operating results or cash flows, depending on which foreign currency exchange rates change and depending on the directional change (either a strengthening or weakening against the U.S. Dollar). As our foreign operations continue to grow, our exposure to foreign currency exchange rate risk may become more significant.

Inflation Risk

We do not believe that inflation has had a material effect on our business, financial condition or results of operations during the periods presented. If our costs were to become subject to significant inflationary pressures, we may not be able to fully offset such higher costs through price increases. Our inability or failure to do so could have a material adverse effect on our business, financial condition and results of operations.

Item 4. Controls and Procedures

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our reports filed under the Securities Exchange Act of 1934, as amended (the Exchange Act) is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s (SEC) regulations, rules and forms and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow for timely decisions regarding required disclosure.

In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures. As required by Rule 13a-15(b) or Rule 15d-15(b) promulgated by the SEC under the Exchange Act, we carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered by this Quarterly Report on Form 10-Q. Based on the foregoing, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of the end of the period covered by this Quarterly Report on Form 10-Q.

There has been no change in our internal control over financial reporting during the quarter ended October 3, 2015 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

The information set forth in Note 13 to the condensed consolidated financial statements under the caption “Litigation” included in Part I, Item 1 of this Quarterly Report on Form 10-Q is incorporated herein by reference.

Item 1A. Risk Factors

Before you decide to invest or maintain an interest in our common stock, you should consider carefully the risks described below, which have been updated since the filing of our Annual Report on Form 10-K for the fiscal year ended January 3, 2015 , filed with the SEC on February 17, 2015 , together with the other information contained in this Quarterly Report on Form 10-Q, and any recent Current Reports on Form 8-K. We believe the risks described below are the risks that are material to us as of the date of this Quarterly Report on Form 10-Q. Other risks and uncertainties, including those not presently known to us or that we do not currently consider material, may also impair our business operations. If any of the following risks comes to fruition, our business, financial condition, results of operations and growth prospects would likely be materially and adversely affected. In these circumstances, the market price of our common stock could decline, and you could lose all or part of your investment or interest.

Risk factors marked with an asterisk (*) below include a substantive change from or an update to the risk factors included in our Annual Report on Form 10-K for the fiscal year ended January 3, 2015 , filed with the SEC on February 17, 2015 .

Risks Related to Our Revenues

We currently derive substantially all of our revenue from our Masimo SET ^® platform, Masimo rainbow ^® SET ^® platform and related products. If this technology and the related products do not continue to achieve market acceptance, our business, financial condition and results of operations would be adversely affected.

We are dependent upon the success and market acceptance of our proprietary Masimo SET ^® technology. Currently, our primary product offerings are based on the Masimo SET ^® platform. Continued market acceptance of products incorporating Masimo SET ^® will depend upon our ability to continue to provide evidence to the medical community that our products are cost-effective and offer significantly improved performance compared to conventional pulse oximeters. Health care providers that currently have significant investments in competitive pulse oximetry products may be reluctant to purchase our products. If hospitals and other health care providers do not believe our Masimo SET ^® platform is cost-effective, safe or more accurate or reliable than competitive pulse oximetry products, they may not buy our products in sufficient quantities to enable us to generate revenue growth from the sale of these products. In addition, allegations regarding the safety and effectiveness of our products, whether or not substantiated, may impair or impede the acceptance of our products. If we are unable to achieve additional market acceptance of our core technology or products incorporating Masimo SET ^® , we will not generate significant revenue growth from the sale of our products, which would adversely affect our business, financial condition and results of operations.

Some of our products, including those based on licensed rainbow ^® technology, are in development or have been recently introduced into the market and may not achieve market acceptance, which could limit our growth and adversely affect our business, financial condition and results of operations.

Products that we have introduced into the market in recent years, including, but not limited to, those based on rainbow ^® technology, a technology that we license, may not be accepted in the market. If our products do not gain market acceptance or if our customers prefer our competitors’ products, our potential revenue growth would be limited, which would adversely affect our business, financial condition and results of operations.

Given that certain rainbow ^® technology products are relatively new to the marketplace, we do not know to what degree the market will accept these products, if at all. Even if our customers recognize the benefits of our products, we cannot assure you that our customers will purchase them in quantities sufficient for us to be profitable or successful. We are continuing to invest in significant sales and marketing resources to achieve market acceptance of these products with no assurance of success. The degree of market acceptance of these products will depend on a number of factors, including:


•	perceived clinical benefits from our products;


•	perceived cost effectiveness of our products;


•	perceived safety and effectiveness of our products;

Table of Contents


•	reimbursement available through Centers for Medicare and Medicaid Services (CMS) programs for using some of our products; and


•	introduction and acceptance of competing products or technologies.

In general, our recent noninvasive measurement technologies are considered disruptive. These recent technologies have performance levels that we believe are acceptable for many clinical environments but may be insufficient in others. In addition, these technologies may perform better in some patients and settings than others. Over time, we hope to continue to improve the performance of these technologies and, if we do, we expect them to become more useful in more environments and to become more widely adopted. While this is the adoption pattern experienced historically with other new noninvasive measurements, such as oxygen saturation, we are unable to guarantee that such adoption pattern will apply to our recent and future technologies.

Our ability to commercialize new products, new or improved technologies and additional applications for Masimo SET ^® and our licensed rainbow ^® technology are each limited to certain markets by our Cross-Licensing Agreement with Cercacor Laboratories, Inc. (Cercacor), which may impair our growth and adversely affect our business, financial condition and results of operations.

In May 1998, we spun off a newly-formed entity, Cercacor, and provided it rights to use Masimo SET ^® to commercialize non-vital signs monitoring applications, while we retained the rights to Masimo SET ^® to commercialize vital signs monitoring applications. On May 2, 1998, we entered into a cross-licensing agreement with Cercacor, which has been amended several times, most recently in an Amended and Restated Cross-Licensing Agreement, effective January 1, 2007 (the Cross-Licensing Agreement). Under the Cross-Licensing Agreement, we granted Cercacor:

•

an exclusive, perpetual and worldwide license, with sublicense rights, to use all Masimo SET ^® owned by us, including all improvements on this technology, for the monitoring of non-vital signs parameters and to develop and sell devices incorporating Masimo SET ^® for monitoring non-vital signs parameters in any product market in which a product is intended to be used by a patient or pharmacist rather than by a professional medical caregiver, which we refer to as the Cercacor Market; and


•	a non-exclusive, perpetual and worldwide license, with sublicense rights, to use all Masimo SET ^® for measurement of vital signs in the Cercacor Market.

Non-vital sign measurements consist of body fluid constituents other than vital sign measurements, including, but not limited to, carbon monoxide, methemoglobin, blood glucose, hemoglobin and bilirubin. Under the Cross-Licensing Agreement, we are only permitted to sell devices utilizing Masimo SET ^® for the monitoring of non-vital signs parameters in markets where the product is intended to be used by a professional medical caregiver, including, but not limited to, hospital caregivers and alternate care facility caregivers, rather than by a patient or pharmacist, which we refer to as the Masimo Market. Accordingly, our ability to commercialize new products, new or improved technologies and additional applications for Masimo SET ^® is limited. In particular, our inability to expand beyond the Masimo Market may impair our growth and adversely affect our business, financial condition and results of operations.

Pursuant to the Cross-Licensing Agreement, we have licensed from Cercacor the right to make and distribute products in the Masimo Market that utilize rainbow ^® technology for certain noninvasive measurements. As a result, the opportunity to expand the market for our products incorporating rainbow ^® technology is also limited, which could limit our ability to maintain or increase our revenue and impair our growth.

*We face competition from other companies, many of which have substantially greater resources than we do. If we do not successfully develop and commercialize enhanced or new products that remain competitive with products or alternative technologies developed by others, we could lose revenue opportunities and customers, and our ability to grow our business would be impaired, adversely affecting our financial condition and results of operations.

A number of our competitors have substantially greater capital resources, larger customer bases and larger sales forces, have established stronger reputations with specific customers, and have built relationships with Group Purchasing Organizations (GPOs) that are more effective than ours. Our Masimo SET ^® platform faces additional competition from companies developing products for use with third-party monitoring systems, as well as from companies that currently market their own pulse oximetry monitors.

The medical device industry is characterized by rapid product development and technological advances, which places our products at risk of obsolescence. Our long-term success depends upon the development and successful commercialization of new products, new or improved technologies and additional applications for Masimo SET ^® and licensed rainbow ^® technology. The research and development process is time-consuming and costly and may not result in products or applications that we can successfully commercialize. In particular, we may not be able to successfully commercialize our products for applications other

Table of Contents

than arterial blood oxygen saturation and pulse rate monitoring, including respiration rate, hemoglobin, carboxyhemoglobin and methemoglobin monitoring. If we do not successfully adapt our products and applications both within and outside these measurements, we could lose revenue opportunities and customers. Furthermore, one or more of our competitors may develop products that are substantially equivalent to our U.S. Food and Drug Administration (FDA) cleared products, or those of our original equipment manufacturer (OEM) partners, whereby they may use our products or those of our OEM partners as predicate devices to more quickly obtain FDA clearance of their competing products. Competition could result in pressure from our customers to reduce the price of our products and fewer orders for our products, which could, in turn, cause a reduction in our revenues and product gross margins, thereby adversely impacting our business, financial condition and results of operations.

We depend on our domestic and international OEM partners for a portion of our revenue. If they do not devote sufficient resources to the promotion of products that use Masimo SET ^® and licensed rainbow ^® technology, our business would be harmed.

We are, and will continue to be, dependent upon our domestic and international OEM partners for a portion of our revenue through their marketing, selling and distribution of certain of their products that incorporate Masimo SET ^® and licensed rainbow ^® technology. Although we expect that our OEM partners will accept and actively market, sell and distribute products that incorporate licensed rainbow ^® technology, they may not elect, and have no contractual obligation, to do so. Because products that incorporate our technologies may represent a relatively small percentage of business for some of our OEM partners, they may have less incentive to promote these products over other products that do not incorporate these technologies. In addition, some of our OEM partners offer products that compete with ours. Therefore, we cannot guarantee that our OEM partners, or any company that may acquire any of our OEM partners, will vigorously promote products incorporating Masimo SET ^® and licensed rainbow ^® technology. The failure of our OEM partners to successfully market, sell or distribute products incorporating these technologies, the termination of OEM agreements, the loss of OEM partners or the inability to enter into future OEM partnership agreements would have a material adverse effect on our business, financial condition and results of operations.

*Medtronic may seek to avoid paying any royalties to us, which would significantly reduce our royalty revenues and adversely affect our business, financial condition and results of operations.

Pursuant to our settlement agreement with Medtronic plc (Medtronic, formerly Covidien), we earn royalties on Medtronic’s total U.S. based pulse oximetry sales. For the nine months ended October 3, 2015 and September 27, 2014 , our royalties from the Medtronic settlement agreement totaled approximately $23.3 million and $22.0 million , respectively. Because these royalty payments do not carry any significant cost, they result in significant improvements to our reported gross profit, operating income levels and earnings per share. As a result, an elimination of royalties that we earn under the settlement agreement in the future would have a significant impact on our revenue, gross margins, operating income and earnings per share.

On January 28, 2011, we entered into a second amendment to the settlement agreement, which became effective on March 15, 2011. Pursuant to the second amendment, in exchange for a specified royalty payment, we agreed not to sue Medtronic for its current pulse oximetry products, but not for any other technologies that Medtronic may add. On October 21, 2015, Medtronic plc filed three separate inter partes review petitions with the Patent Trial and Appeal Board of the U.S. Patent and Trademark Office, challenging several of the claims of two U.S. patents titled “Signal processing apparatus” that are owned by us. Medtronic has the right to stop paying us royalties, subject to certain notice requirements, and has informed us that it will terminate the covenants they received from us under the settlement agreement and stop paying royalties when it feels it has reached an appropriate point in the process. If Medtronic ceases paying royalties to us under the settlement agreement, our revenue, gross margins, operating income and earnings per share would be materially and adversely affected.

*If we fail to maintain or develop relationships with GPOs, sales of our products would decline.

Our ability to sell our products to U.S. hospitals depends, in part, on our relationships with GPOs. Many existing and potential customers for our products become members of GPOs. GPOs negotiate beneficial pricing arrangements and contracts, which are sometimes exclusive, with medical supply manufacturers and distributors.

These negotiated prices are made available to a GPO’s affiliated hospitals and other members. If we are not one of the providers selected by a GPO, the GPO’s affiliated hospitals and other members may be less likely or unlikely to purchase our products. If a GPO has negotiated a strict sole source, market share compliance or bundling contract for another manufacturer’s products, we may be prohibited from making sales to members of the GPO for the duration of such contractual arrangement. For the nine months ended October 3, 2015 and September 27, 2014 , shipments of our pulse oximetry products to customers that are members of GPOs represented approximately $251.9 million and $228.9 million , respectively, of our revenue from sales to U.S. hospitals. Our failure to renew our contracts with GPOs may cause us to lose market share and could have a material adverse effect on our business, financial condition and results of operations. In addition, if we are unable to develop

Table of Contents

new relationships with GPOs, our competitive position would likely suffer and our opportunities to grow our revenues and business would be harmed.

Certain GPOs are creating, coordinating and facilitating regional purchasing coalition (RPC) supply chain networks that include anti-competitive practices such as sole sourcing and bundling. These RPCs circumvent and potentially violate rules of conduct for GPOs and have the effect of reducing product purchasing decisions available to the hospitals that belong to these regional organizations. If the GPOs and RPCs are permitted to continue practices that limit, reduce or eliminate competition, we could lose customers who are no longer able to choose to purchase our products, resulting in lower sales that could adversely affect our business, financial condition and results of operations.

Inadequate levels of coverage or reimbursement from governmental or other third-party payers for our products, or for procedures using our products, may cause our revenue to decline.

Sales of our products depend in part on the reimbursement and coverage policies of governmental and private health care payers. The ability of our health care provider customers, including hospitals, to obtain adequate coverage and reimbursement for our products or the procedures in which our products are used may impact our customers’ purchasing decisions. Therefore, our customers’ inability to obtain adequate coverage, reimbursement for our products or reimbursement for the procedures in which our products are used would have a material adverse effect on our business.

Third-party payers have adopted, and are continuing to adopt, health care policies intended to curb rising health care costs. These policies include, among others:


•	controls on reimbursement for health care services and price controls on medical products and services;


•	limitations on coverage and reimbursement for new medical technologies and procedures; and


•	the introduction of managed care and prospective payment systems in which health care providers contract to provide comprehensive health care for a fixed reimbursement amount per person or per procedure.

We cannot guarantee that governmental or third-party payers will reimburse, or continue to reimburse, a customer for the cost of our products or the procedures in which our products are used. In fact, some payers have indicated that they are not willing to reimburse for certain of our products or for the procedures in which our products are used. For example, some insurance carriers have issued policies denying coverage for transcutaneous hemoglobin measurement on the grounds that the technology is investigational in the outpatient setting. Other payers are continuing to investigate our products to determine if they will provide reimbursement to our customers. While we are working with these payers to obtain reimbursement, we may not be successful. These trends could lead to pressure to reduce prices for our current and future products and could cause a decrease in the size of the market or a potential increase in competition that could have a material adverse effect on our business, financial condition and results of operations.

Our customers may reduce, delay or cancel purchases due to a variety of factors, such as lower hospital census levels or third-party guidelines, or may require that we reduce the price of our products, which could adversely affect our business, financial condition and results of operations.

Our customers are facing growing levels of uncertainties, such as lower overall hospital census for paying patients and the impact of that lower census on hospital budgets. In addition, although not yet fully understood, the impact of the Patient Protection and Affordable Care Act may force hospitals to reevaluate their entire cost structure, including the amount of capital they allocate to medical device technologies and products. Such developments could have a significant negative impact on our OEM customers who, due to their traditionally larger capital equipment sales model, could see declines in purchases from their hospital customers. This, in turn, could reduce our board sales to our OEM customers. In addition, certain of our products, including our rainbow ^® measurements such as carbon monoxide, methemoglobin and hemoglobin, that are sold with upfront license fees and more complex and expensive sensors could also be impacted by hospital budget reductions.

In addition, states and other local regulatory authorities may issue guidelines regarding the appropriate scope and use of our products from time to time. For example, some of our noninvasive monitoring devices may be subject to authorization by individual states as part of the Emergency Medical Services scope of practice procedures. Although a lack of inclusion into scope of practice procedures does not prohibit usage, it may limit adoption.

Additionally, as a result of the continued consolidation in the health care industry, we may experience decreasing prices for our products due to the potential increased market pricing power of our health care provider customers. If these and other competitive forces drive down the price of our products, and we are not able to counter that pressure with cost reductions to our existing products or the introduction of new higher priced products, our product gross profit margins will decline. This, in turn, could have a material adverse effect on our business, financial condition and results of operations.

*The loss of any large customer or distributor, or any cancellation or delay of a significant purchase by a large customer, could reduce our net sales and harm our operating results.

We have a concentration of OEM, distribution and direct customers. If for any reason we were to lose our ability to sell to a specific group or class of customers, or through a distributor, we could experience a significant reduction in revenue, which would adversely impact our operating results. Also, we cannot provide any assurance that we will retain our current customers, groups of customers or distributors, or that we will be able to attract and retain additional customers in the future. For the nine months ended October 3, 2015 and September 27, 2014 , we had sales through two just-in-time distributors, which in total represented approximately 26.7% and 25.4% , respectively, of our total revenue. The loss of any large customer or distributor could have a material adverse effect on our business, financial condition and results of operations.

*Imitation Masimo sensors and third-party medical device reprocessors that reprocess our single-patient-use sensors may harm our reputation. Also, these imitation and third-party reprocessed sensors, as well as genuine Masimo reprocessed sensors, are sold at lower prices than new Masimo sensors and could cause our revenue to decline, which may adversely affect our business, financial condition and results of operations.

We are aware that other organizations are manufacturing and selling imitation Masimo sensors. In addition, we are aware that certain medical device reprocessors have been collecting our used single-patient-use sensors from hospitals and then reprocessing, repackaging and reselling those sensors to hospitals. These imitation and third-party reprocessed sensors are sold at lower prices than new Masimo sensors. Our experience with both these imitation sensors and third-party reprocessed sensors is that they provide inferior performance, increased sensor utilization, reduced comfort and a number of monitoring problems. Notwithstanding these limitations, some of our customers have indicated a willingness to consider purchasing some of their sensor requirements from these imitation manufacturers and third-party reprocessors in an effort to reduce their overall operating costs. These imitation and reprocessed sensors have led and may continue to lead to confusion with our genuine Masimo products; have reduced and may continue to reduce our revenue; and, in some cases, have harmed and may continue to harm our reputation if customers conclude incorrectly that these imitation or reprocessed sensors are original Masimo sensors. In addition, we have expended a significant amount of time and expense investigating issues caused by imitation and reprocessed sensors, troubleshooting problems stemming from such sensors, educating customers about why imitation and reprocessed sensors do not perform to their expectations, enforcing our proprietary rights against the imitation manufacturers and reprocessors, and enforcing our contractual rights under our customer contracts.

In response to these imitation sensors and third-party reprocessors, we offer to our customers our own Masimo reprocessed sensors, which we re-manufacture and test to ensure that they meet the same performance specifications as our new Masimo sensors. In addition, we have incorporated X-Cal ^™ technology into certain products to ensure our customers get the performance they expect by using genuine Masimo sensors. We believe this technology will help ensure that hospitals, clinicians and, ultimately, their patients receive true Masimo measurement quality and performance, and will curtail some of the harm to us that results when customers experience performance and other problems with imitation and reprocessed sensors. However, some customers may object to the X-Cal ^™ technology, potentially resulting in the loss of customers and revenues. In addition, reprocessed sensors sold by Masimo are generally offered at a lower price and, therefore, may reduce certain customer demand for our new sensors. As a result, increased sales of genuine Masimo reprocessed sensors may result in lower revenues, which could negatively impact our business, financial condition and results of operations.

*From time to time, we may carry out strategic initiatives that may not be viewed favorably by our customers, or that could negatively impact our business, financial condition and results of operations.

We expect to continue to carry out strategic initiatives and investments that we believe are necessary to grow our revenues and expand our business, both in the United States and abroad. For example, since 2013, we have made investments in a new worldwide blood management sales force whose primary focus is to work with hospitals to identify new opportunities for our noninvasive hemoglobin measurement, SpHb ^® . Although we believe strategic initiatives and investments, including our investment in the new worldwide blood management sales force, are, and will continue to be, in the long-term best interests of Masimo and our stockholders, there are no assurances that such initiatives and investments will yield favorable results for us. Accordingly, if these initiatives and investments are not viewed favorably by our customers, our business, financial condition and results of operations could be adversely affected.

Risks Related to Our Intellectual Property

If the patents we own or license, or our other intellectual property rights, do not adequately protect our technologies, we may lose market share to our competitors and be unable to operate our business profitably.

Our success depends significantly on our ability to protect our rights to the technologies used in our products, including Masimo SET ^® and licensed rainbow ^® technology. We rely on patent protection, trade secrets and a combination of copyright and trademark laws, as well as nondisclosure, confidentiality and other contractual arrangements, to protect our technology and rights. However, these legal means afford only limited protection and may not adequately protect our rights or permit us to gain or maintain any competitive advantage. In addition, we cannot be assured that any of our pending patent applications will result in the issuance of a patent to us. The U.S. Patent and Trademark Office (the PTO) may deny or require a significant narrowing of claims in our pending patent applications, and patents issued as a result of the pending patent applications, if any, may not provide us with significant commercial protection or be issued in a form that is advantageous to us. We could also incur substantial costs in proceedings before the PTO.

On September 16, 2011, the Leahy-Smith America Invents Act (the Leahy-Smith Act), which includes a number of significant changes to U.S. patent law, was signed into law. The provisions of the Leahy-Smith Act include changes in the way patent applications will be prosecuted, including a transition to a “first-to-file” system for deciding which party should be granted a patent when two or more patent applications are filed by different parties claiming the same invention, and may also affect patent litigation. Under a “first-to-file” system, a third-party that files a patent application with the PTO before us could be awarded a patent covering an invention of ours even if we made the invention before it was made by the third-party. The PTO has developed new and untested regulations and procedures to govern the full implementation of the Leahy-Smith Act. Many of the substantive changes to patent law associated with the Leahy-Smith Act and, in particular, the “first-to-file” provisions, became effective in March 2013. Additionally, the Leahy-Smith Act introduced procedures that may make it easier for third parties to challenge issued patents, as well as to intervene in the prosecution of patent applications, and, as a result, our issued patents, and those that may be issued or licensed in the future, may expire or be challenged, invalidated or circumvented, which could limit our ability to stop competitors from marketing related technologies. Furthermore, the Leahy-Smith Act contains new statutory provisions that require the PTO to issue new regulations for their implementation, and it may take the courts years to interpret the provisions of the new statute. Accordingly, it is not clear what, if any, impact the Leahy-Smith Act will have on our business, the cost of prosecuting our licensed and future patent applications, our ability to obtain patents based on our licensed and future patent applications and our ability to enforce or defend our licensed or future issued patents. The Leahy-Smith Act and its implementation could increase the uncertainties and costs surrounding the prosecution of our pending and future patent applications and the enforcement or defense of our issued and future patents, all of which could have a material adverse effect on our business, financial condition and results of operations.

Some of our patents related to our Masimo SET ^® algorithm technology began to expire in March 2011. Additionally, upon expiration of other issued or licensed patents, we may lose some of our rights to exclude competitors from making, using, selling or importing products using the technology based on the expired patents. While we seek to offset potential losses relating to important expiring patents by securing additional patents on commercially desirable improvements, there can be no assurance that we will be successful in securing such additional patents, or that such additional patents will adequately offset the effect of expiring patents. For example, the U.S. Supreme Court has ruled on several patent cases in recent years, either narrowing the scope of patent protection available in certain circumstances or weakening the rights of patent owners in certain situations. In addition to increasing uncertainty with regard to our ability to obtain patents in the future, this combination of events has created uncertainty with respect to the value of patents once obtained. Depending on decisions by the U.S. Congress, the federal courts and the PTO, the laws and regulations governing patents could change in unpredictable ways that would weaken our ability to obtain new patents or to enforce patents that we might obtain in the future. Additionally, there is no assurance that competitors will not be able to design around our patents.

We also rely on contractual rights with the third parties that license technology to us to protect our rights in such licensed technology. In addition, we rely on unpatented proprietary technology. We cannot assure you that we can meaningfully protect all of our rights in our unpatented proprietary technology or that others will not independently develop substantially equivalent proprietary products or processes or otherwise gain access to our unpatented proprietary technology.

We seek to protect our know-how and other unpatented proprietary technology with confidentiality agreements and intellectual property assignment agreements with our employees, OEM partners, independent distributors and consultants. However, such agreements may not be enforceable or may not provide meaningful protection for our proprietary information in the event of unauthorized use or disclosure or other breaches of the agreements or in the event that our competitors discover or independently develop similar or identical designs or other proprietary information. In addition, we rely on the use of registered and common law trademarks with respect to the brand names of some of our products. Common law trademarks provide less

Table of Contents

protection than registered trademarks. Loss of rights in our trademarks could adversely affect our business, financial condition and results of operations.

Furthermore, the laws of foreign countries may not protect our intellectual property rights to the same extent as the laws of the U.S. If we fail to apply for intellectual property protection or if we cannot adequately protect our intellectual property rights in these foreign countries, our competitors may be able to compete more effectively against us, which could adversely affect our competitive position, as well as our business, financial condition and results of operations.

*If third parties claim that we infringe their intellectual property rights, we may incur liabilities and costs and may have to redesign or discontinue selling certain products.

Companies in the medical device industry have used intellectual property litigation to gain a competitive advantage in the marketplace. We face the risk of claims that we have infringed on third parties’ intellectual property rights. Searching for existing intellectual property rights may not reveal important intellectual property and our competitors may also have filed for patent protection, which is not publicly-available information, or claimed trademark rights that have not been revealed through our availability searches. In addition, many of our employees were previously employed at other medical device companies. We may be subject to claims that our employees have disclosed, or that we have used, trade secrets or other proprietary information of our employees’ former employers. Our efforts to identify and avoid infringing on third parties’ intellectual property rights may not always be successful. Any claims of patent or other intellectual property infringement against us, even those without merit, could:


•	increase the cost of our products;


•	be expensive and time consuming to defend;


•	result in us being required to pay significant damages to third parties;


•	force us to cease making or selling products that incorporate the challenged intellectual property;


•	require us to redesign, reengineer or rebrand our products, product candidates and technologies;


•	require us to enter into royalty or licensing agreements in order to obtain the right to use a third-party’s intellectual property on terms that may not be favorable or acceptable to us;


•	require us to indemnify third parties pursuant to contracts in which we have agreed to provide indemnification for intellectual property infringement claims;


•	divert the attention of our management and other key employees;


•	result in our customers or potential customers deferring or limiting their purchase or use of the affected products impacted by the claims until the claims are resolved; and


•	otherwise have a material adverse effect on our business, financial condition and results of operations.

In addition, new patents obtained by our competitors could threaten the continued commercialization of our products in the market even after they have already been introduced. Philips Electronics North America Corporation and Shenzhen Mindray Bio-Medical Electronics Co., Ltd. have each filed antitrust and patent infringement counterclaims against us, as further described in Note 13 to the condensed consolidated financial statements under the caption “Litigation” of this Quarterly Report on Form 10-Q.

*We believe competitors may currently be violating and may in the future violate our intellectual property rights, and we may bring additional litigation to protect and enforce our intellectual property rights, which may result in substantial expense and may divert management’s attention from implementing our business strategy.

We believe that the success of our business depends, in significant part, on obtaining patent protection for our products and technologies, defending our patents and preserving our trade secrets. We were previously involved in significant litigation to protect our patent position and may be required to engage in further litigation. In 2006, we settled a costly, six-year lawsuit against Mallinckrodt, Inc., part of Tyco Healthcare (currently Medtronic), and one of its subsidiaries, Nellcor Puritan Bennett, Inc., in which we claimed infringement of some of our pulse oximetry signal processing patents.

In February 2009, we filed a patent infringement suit against Philips Electronics North America Corporation and Philips Medizin Systeme Böblingen GmbH (collectively, Philips) related to Philips’ FAST pulse oximetry technology and certain of Philips’ patient monitors. In each of December 2012 and December 2013, we filed patent infringement and breach of contract suits against Mindray DS USA, Inc., Shenzhen Mindray Bio-Medical Electronics Co., Ltd., and Mindray Medical International Ltd. (collectively, Mindray). These suits are described in Note 13 to the condensed consolidated financial statements under the caption “Litigation” of this Quarterly Report on Form 10-Q. Both Philips and Mindray are OEM partners of ours. There is no guarantee that we will prevail in these suits or receive any damages or other relief if we do prevail.

Table of Contents

On October 21, 2015, Medtronic filed three separate inter partes review petitions (the Petitions) with the Patent Trial and Appeal Board (the PTAB) of the U.S. Patent and Trademark Office (PTO), challenging several of the claims related to certain of our U.S. patents. A patentability trial will commence if the PTAB decides to institute the inter partes review proceedings after considering the Petitions and our preliminary response to the Petitions. If the PTAB institutes the proceedings, we intend to defend the ’393 Patent and the ’034 Patent. The Petitions are described in Note 13 to the condensed consolidated financial statements under the caption “Litigation” of this Quarterly Report on Form 10-Q. There is no guarantee that we will prevail in these proceedings or receive any reimbursement of expenses or other relief if we do prevail.

Our ongoing and future litigation could result in significant additional costs and further divert the attention of our management and key personnel from our business operations and the implementation of our business strategy and may not be adequate to protect our intellectual property rights.

Risks Related to Our Regulatory Environment

*Our failure to obtain and maintain FDA clearances or approvals on a timely basis, or at all, would prevent us from commercializing our current or upgraded products in the United States, which could severely harm our business.

Each medical device that we wish to market in the U.S. generally must first receive 510(k) clearance from the FDA pursuant to the Federal Food, Drug, and Cosmetic Act (FDCA) by filing a 510(k) pre-market notification, receiving clearance through the de novo review process, or obtaining pre-market approval by submitting a pre-market approval (PMA) application. Even if regulatory clearance or approval of a product is granted, the clearance or approval may be subject to limitations on the indicated uses for which the product may be marketed. We cannot guarantee that the FDA will grant 510(k) clearance on a timely basis, if at all, for new products or uses that we propose for Masimo SET ^® or licensed rainbow ^® technology. The traditional FDA 510(k) clearance process for our products has generally taken between three to six months. However, over the past few years, we have experienced a significantly longer 510(k) clearance review process. Our more recent experience and interactions with the FDA, along with information we have received from other medical device manufacturers, suggests that, in some cases, the FDA is requiring applicants to provide much more or different information and data for 510(k) clearance than it had previously required; and that the FDA may not rely on approaches that it had previously accepted to support 510(k) clearance, thereby leading to more review cycles or to decisions that may not be substantially the same as previous equivalent decisions. As a result, we have experienced lengthier FDA 510(k) review periods over the past few years, which has delayed the 510(k) clearance process for our products over this period as compared to prior periods.

In connection with a recent FDA 510(k) filing for certain improvements to our Pronto-7 ^® product, the FDA expressed concerns and requested additional information regarding the methods we used to validate the SpHb ^® parameter. We responded to the FDA’s request for additional information on March 25, 2014. The FDA responded that the remaining issues would not likely be resolved in the time remaining, so we voluntarily withdrew the application on March 31, 2014. We have since had further discussions with the FDA and believe we have a better understanding of the FDA’s expectations on validation methodologies for future 510(k) filings for SpHb spot-check devices such as Pronto and Pronto-7 ^® . We intend to work with the FDA to address whatever remaining concerns the agency has, but we cannot be sure we will be able to resolve those concerns.

To date, the FDA has regulated pulse oximeters incorporating Masimo SET ^® and licensed rainbow ^® technology, patient monitor devices, sensors, cables and other products under the 510(k) process. Although 510(k) clearances have been obtained for such products, if substantial safety or effectiveness problems develop with our devices, we would need to recall our devices. Furthermore, our new products or significantly modified marketed products could be denied 510(k) clearance and be required to undergo the more burdensome PMA process. The process of obtaining PMA is much more costly, lengthy and uncertain than the process for obtaining 510(k) clearance and generally takes one to three years, but may be longer.

We recently launched our iSpO ₂ ^® and MightySat ^™ pulse oximeters, which are not intended for medical use. We are marketing these products in accordance with the FDA’s current policy and enforcement discretion, which indicates that pulse oximeters that are not intended for medical purposes can be marketed directly to consumers without first obtaining 510(k) clearance. In addition, some of our products may also be exempted from the 510(k) process in accordance with specific FDA guidance and policies, such as the FDA guidance related to mobile medical applications. We cannot assure you that the FDA will not change its policy regarding the regulation of these products. If the FDA changes its policy or concludes that our marketing of these products is not in accordance with its current policy, we may be required to seek 510(k) clearances to market these devices.

Table of Contents

The failure of our OEM partners to obtain required FDA clearances or approvals for products that incorporate our technologies could have a negative impact on our revenue.

Our OEM partners are required to obtain their own FDA clearances for products incorporating Masimo SET ^® and licensed rainbow ^® technology to market these products in the U.S. We cannot guarantee that the FDA clearances we have obtained will make it easier for our OEM partners to obtain clearances of products incorporating these technologies, or that the FDA will ever grant clearances on a timely basis, if at all, for any future product incorporating Masimo SET ^® and licensed rainbow ^® technology that our OEM partners propose to market.

*If we or our suppliers fail to comply with ongoing regulatory requirements, or if we experience unanticipated problems with our products, these products could be subject to restrictions or withdrawal from the market.

Our products, along with the manufacturing processes, labeling and promotional activities for our products, are subject to continual review and periodic inspections by the FDA and other regulatory bodies. Among other requirements, we and our suppliers are required to comply with the FDA’s Quality System Regulation (QSR), which covers the methods and documentation of the design, control testing, production, component suppliers control, quality assurance, complaint handling, labeling control, packaging, storage and shipping of our products. The FDA enforces the FDA’s QSR through announced and unannounced inspections. We are also subject to similar state requirements and licenses.

In 2013, the FDA inspected our facility in Irvine, California and issued an FDA Form 483 listing observations the investigator believed may constitute violations of statutes or regulations administered by the FDA, including observations relating to complaint handling, medical device reporting and corrective and preventative action (CAPA) procedures. In 2014, the FDA also inspected our facility in Mexicali, Mexico and issued a Form 483 listing observations relating to our CAPA procedures, documentation practices associated with our device history records and procedures for employee training. We submitted responses to both Form 483s. In August 2014, we received from the FDA a final inspection report closing out the Mexicali inspection and a warning letter (the Warning Letter) related to the Irvine inspection. We submitted a response (the Response Letter) to the Warning Letter on September 5, 2014 and held a regulatory meeting with the FDA on September 19, 2014. At the meeting, in addition to discussing our Response Letter, the FDA raised issues beyond the scope of the Warning Letter in the areas of Good Manufacturing Practices, quality, bioresearch monitoring and labeling/promotion. We have been in communication with the FDA since the meeting and are working to resolve the issues raised by the FDA. In the meantime, we are currently unable to obtain and/or renew Certificates to Foreign Governments (CFGs) that have recently expired for our products, which may prevent us from registering or importing products into certain countries that require CFGs, including Argentina, China and Thailand. We do not know what further actions, if any, the FDA will take in connection with these issues. If we are unable to resolve the issues raised by the FDA, our business, financial condition and results of operations could be adversely affected.

In December 2014, the California Department of Public Health, Food and Drug Branch (Food and Drug Branch) conducted an inspection of our facility in Irvine, California, and issued a Notice of Violation listing observations relating to complaint handling and CAPA procedures that the investigator believed may constitute violations of California statutes or regulations. We responded to the Notice of Violation in January 2015 and are working to resolve the issues raised by the Food and Drug Branch. We do not know what further actions, if any, the Food and Drug Branch will take in connection with these issues.

Failure by us or one of our suppliers to comply with statutes and regulations administered by the FDA and other regulatory bodies or failure to adequately respond to any FDA Form 483 observations, any Food and Drug Branch notices of violation or any similar reports could result in, among other things, any of the following items:


•	warning letters or untitled letters issued by the FDA;


•	fines, civil penalties, in rem forfeiture proceedings, injunctions and criminal prosecution;


•	import alerts;


•	unanticipated expenditures to address or defend such actions;


•	delays in clearing or approving, or refusal to clear or approve, our products;


•	withdrawal or suspension of clearance or approval of our products or those of our third-party suppliers by the FDA or other regulatory bodies;


•	product recall or seizure;


•	orders for physician notification or device repair, replacement or refund;


•	interruption of production or inability to export to certain foreign countries; and


•	operating restrictions.

Table of Contents

If any of these items were to occur, it would harm our reputation and adversely affect our business, financial condition and results of operations.

Failure to obtain regulatory approval in foreign jurisdictions will prevent us from marketing our products abroad.

We currently market and intend to continue to market our products internationally. Outside of the U.S., we can market a product only if we receive a marketing authorization and, in some cases, pricing approval, from the appropriate regulatory authorities. The regulatory registration/licensing process varies among international jurisdictions and may require additional testing. The time required for international registration of new products may differ from that required for obtaining FDA clearance. The foreign registration/licensing process may include all of the risks associated with obtaining FDA clearance in addition to other risks. We may not obtain foreign regulatory registration/licensing on a timely basis, if at all. FDA clearance does not ensure new product registration/licensing by foreign regulatory authorities. Clearance by one foreign regulatory authority does not ensure clearance by any other foreign regulatory authority or by the FDA. If we fail to receive necessary approvals to commercialize our products in foreign jurisdictions on a timely basis, or at all, our business, financial condition and results of operations could be adversely affected.

Modifications to our marketed devices may require new regulatory clearances or premarket approvals, or may require us to cease marketing or to recall the modified devices until clearances or approvals are obtained.

We have made modifications to our devices in the past and we may make additional modifications in the future. Any modifications to an FDA-cleared device that could significantly affect its safety or effectiveness or that would constitute a major change in its intended use would require a new 510(k) clearance or possibly PMA. We may not be able to obtain such clearances or approvals in a timely fashion, or at all. Delays in obtaining future clearances would adversely affect our ability to introduce new or enhanced products in a timely manner, which in turn would have an adverse effect on our business, financial condition and results of operations. If the FDA disagrees with our conclusion and requires new clearances or approvals for the modifications, we may be required to recall and to stop marketing the modified devices, which could have an adverse effect on our business, financial condition and results of operations.

Federal regulatory reforms may make it difficult to maintain or attain approval to develop and commercialize our products and technologies.

From time to time, legislation is drafted and introduced in Congress that could significantly change the statutory provisions governing the clearance or approval, manufacture and marketing of medical devices. In addition, FDA regulations and guidance are often revised or reinterpreted by the FDA in ways that may significantly affect our business and our products. It is impossible to predict whether legislative changes will be enacted or FDA regulations, guidance or interpretations will be changed, and what the impact of such changes, if any, may be. However, any future regulatory changes could make it more difficult for us to maintain or attain approval to develop and commercialize our products and technologies.

If our products cause or contribute to a death or serious injury, we will be subject to medical device reporting regulations, which can result in voluntary corrective actions or agency enforcement actions, including recall of our products.

Under the FDA medical device reporting regulations, we are required to report to the FDA any incident in which a product of ours may have caused or contributed to a death or serious injury or in which a product of ours malfunctioned and, if the malfunction were to recur, would likely cause or contribute to death or serious injury. In addition, all manufacturers placing medical devices in European Union (EU) markets are legally required to report any serious or potentially serious incidents involving devices produced or sold by the manufacturer to the relevant authority in those jurisdictions where any such incident occurred.

The FDA and similar foreign governmental authorities have the authority to require the recall of our commercialized products in the event of material deficiencies or defects in, for example, design, labeling or manufacture. In the case of the FDA, the authority to require a recall generally must be based on an FDA finding that there is a reasonable probability that the device would cause serious injury or death. Manufacturers may, under their own initiative, recall a product if any material deficiency in a device is found or they become aware of a safety issue involving a marketed product. A government-mandated or voluntary recall by us or by one of our distributors could occur as a result of component failures, manufacturing errors, design or labeling defects or other deficiencies and issues. We may initiate certain voluntary recalls involving our products in the future. Recalls of any of our products would divert managerial and financial resources and have an adverse effect on our financial condition and results of operations.

Table of Contents

Since our inception, we have initiated fourteen field actions related to our products, none of which were material to our operating results. All field actions involving “reportable events” were reported to the FDA and other foreign regulatory agencies within the appropriate regulatory timeframes. Because of our dependence upon patient and physician perceptions, any negative publicity associated with these or any future voluntary recalls could materially and adversely affect our business, financial condition, results of operations and growth prospects.

Off-label promotion of our products or promotional claims deemed false or misleading could subject us to substantial penalties.

We must have adequate substantiation for our product performance claims. Obtaining 510(k) clearance only permits us to promote our products for the uses specifically cleared by the FDA. Use of a device outside its cleared or approved indications is known as “off-label” use. Physicians may use our products off-label because the FDA does not restrict or regulate a physician’s choice of treatment within the practice of medicine. Although we may request additional cleared indications for our current products, the FDA may deny those requests, require additional expensive clinical data to support any additional indications or impose limitations on the intended use of any cleared product as a condition of clearance. If the FDA determines that we or our OEM partners have promoted our products for off-label use or have made false or misleading or inadequately substantiated promotional claims, it could request that we or our OEM partners modify those promotional materials or take regulatory or enforcement actions, including the issuance of an untitled letter, warning letter, injunction, seizure, civil fine and criminal penalties. It is also possible that other federal, state or foreign enforcement authorities may take action if they consider our promotional or training materials to constitute promotion of an uncleared or unapproved use, which could also result in significant fines or penalties under other statutory authorities, such as laws prohibiting false claims for reimbursement. In either event, in addition to potential extensive fines and penalties, our reputation could be damaged and adoption of our products would be impaired. Although our policy is to refrain from statements that could be considered off-label promotion of our products, the FDA or another regulatory agency could conclude that we have engaged in off-label promotion. In addition, the off-label use of our products may increase the risk of injury to patients and, in turn, the risk of product liability claims. Product liability claims are expensive to defend and could divert our management’s attention and result in substantial damage awards against us.

*We may be subject to or otherwise affected by federal and state health care laws, including fraud and abuse and health information privacy and security laws, and could face substantial penalties if we are unable to fully comply with these laws.

Although we do not provide health care services or receive payments directly from Medicare, Medicaid or other third-party payers for our products or the procedures in which our products are used, health care regulation by federal and state governments will impact our business. Health care fraud and abuse laws potentially applicable to our operations include, but are not limited to:


•	the Federal Anti-Kickback Statute, which prohibits, among other things, knowingly and willfully offering, paying, soliciting or receiving any bribe, kickback or other remuneration intended to induce the purchase, order or recommendation of an item or service reimbursable under a federal health care program (such as the Medicare or Medicaid programs);


•	federal false claims laws which prohibit, among other things, knowingly and willfully presenting, or causing to be presented, claims for payment from Medicare, Medicaid or other third-party payers that are false or fraudulent;


•	the provisions of the federal Health Insurance Portability and Accountability Act of 1996 (HIPAA), which established federal crimes for knowingly and willfully executing a scheme to defraud any health care benefit program or making false statements in connection with the delivery of or payment for health care benefits, items or services; and


•	state laws analogous to each of the above federal laws, such as state anti-kickback and false claims laws that may apply to items or services reimbursed by non-governmental third-party payers, including commercial insurers, and state laws governing the privacy of certain patient identifiable health information (PHI).

Federal and state false claims laws prohibit anyone from presenting, or causing to be presented, claims for payment to third-party payers that are false or fraudulent. For example, the federal Civil False Claims Act imposes liability on any person or entity that, among other things, knowingly and willfully presents, or causes to be presented, a false or fraudulent claim for payment by a federal health care program, including Medicaid and Medicare. Some suits filed under the Civil False Claims Act, known as “qui tam” actions, can be brought by a private individual, referred to as a “whistleblower” or “relator,” on behalf of the government, and such individuals may share in any amounts paid by the entity to the government in fines or settlement. Such complaints are filed under seal and remain sealed until the applicable court orders otherwise. In recent years, the number of suits brought by private individuals has increased dramatically. Manufacturers, like us, can be held liable under false claims

laws, even if they do not submit claims to the government, if they are found to have caused medical care providers to have submitted claims to the government for payment for a service or the use of a device that is not properly covered for government reimbursement. A number of states also have false claims laws, and some of these laws may apply to claims for items or services reimbursed under Medicaid and/or commercial insurance. Sanctions under these federal and state laws may include civil monetary penalties, exclusion of a manufacturer’s products from reimbursement under government programs and imprisonment. In particular, when an entity is determined to have violated the federal Civil False Claims Act, it may be required to pay up to three times the actual damages sustained by the government, plus civil penalties of $5,500 to $11,000 for each separate false claim.

In April 2011, we were informed by the United States Attorney’s Office for the Central District of California, Civil Division, that a qui tam complaint had been filed against us in the U.S. District Court for the Central District of California by three of our former physician office sales representatives. The qui tam complaint alleged, among other things, that our noninvasive hemoglobin products failed to meet their accuracy specifications, and that we misled the FDA and customers regarding the accuracy of the products. In November 2011, the United States declined to intervene in the case, and in October 2013, the District Court granted summary judgment in our favor. The former sales representatives have appealed the District Court’s decision. We are unable to predict the final outcome of the qui tam action. A reversal of the District Court’s decision in this matter could have a material adverse effect on our financial condition or results of operations in the future.

In the third quarter of 2013, we were notified that the FDA and the United States Attorney’s Office for the Central District of California, Criminal Division (USAO), were investigating the allegations regarding our noninvasive hemoglobin products. In the second quarter of 2014, we received grand jury subpoenas requesting documents pertaining to, among other things, the testing, marketing and sales of our Pronto ^® and Pronto-7 ^® products. On May 7, 2015, we received a letter from the USAO stating that, as of the date of the letter, the USAO had decided not to initiate any criminal charges against us or any of our current or former employees in connection with its investigation. The USAO reserved the right to revisit its decision at any time.

We have certain arrangements with hospitals that may be affected by health care fraud and abuse laws. For instance, under our standard customer arrangements, we provide hospitals with free pulse oximetry monitoring devices in exchange for their agreement to purchase future pulse oximetry sensor requirements from us. In addition, we occasionally provide our customers with rebates in connection with their annual purchases. While we believe that these arrangements are structured such that we are currently in compliance with applicable federal and state health care laws, one or more of these arrangements may not meet the Federal Anti-Kickback Statute’s safe harbor requirements, which may result in increased scrutiny by government authorities that are responsible for enforcing these laws.

There can be no assurance that we will not be found to be in violation of any of such laws or other similar governmental regulations to which we are directly or indirectly subject and, as a result, we may be subject to penalties, including civil and criminal penalties, damages, fines, exclusion of our products from reimbursement under Medicare, Medicaid and other federal health care programs, and the curtailment or restructuring of our operations. Any penalties could adversely affect our ability to operate our business and our financial results. Any action against us for violation of these laws, even if we successfully defend against such action, could cause us to incur significant legal expenses and divert our management’s attention from the operation of our business.

Further, we are required to comply with federal and state laws governing the transmission, security and privacy of individually identifiable PHI that we may obtain or have access to in connection with the manufacture and sale of our products. We may be required to make costly system modifications to comply with the HIPAA privacy and security requirements. In addition, if we do not properly comply with existing or new laws and regulations related to the protection of health information, we could be subject to criminal or civil sanctions, the potential enforcement of which is greater as a result of the Health Information Technology of Economic and Clinical Health Act.

Numerous other federal and state laws protect the confidentiality of PHI, including state medical information privacy laws, state social security number protection laws and state and federal consumer protection laws. In some cases, more protective state privacy and security laws are not preempted by HIPAA and may be subject to interpretation by various governmental authorities and courts, resulting in potentially complex compliance issues for us and our customers.

In addition, state and federal human subject protection laws apply to our receipt of individually identifiable PHI in connection with clinical research. These laws could create liability for us if one of our research collaborators uses or discloses research subject information without authorization and in violation of applicable laws.

We may incur significant costs and potential liabilities in defending our new products and technologies in various legal and other proceedings.

Our breakthrough noninvasive measurement technologies are new and not yet widely understood or accepted. These new technologies may become the subject of various legal and other proceedings. We may incur significant costs in explaining and defending our new products and technologies in these proceedings, often to non-technical audiences. The outcomes of these proceedings are unpredictable and may result in significant liabilities, regardless of the merits of the claims made in the proceedings.

*Legislative and regulatory changes in the health care industry could have a negative impact on our financial performance. Furthermore, our business, financial condition, results of operations and cash flows could be significantly and adversely affected by health care reform legislation in the U.S. or if reform programs are adopted in our key markets.

Changes in the health care industry in the U.S. and elsewhere could adversely affect the demand for our products as well as the way in which we conduct our business. In 2010, President Obama signed health care reform legislation into law that required most individuals to have health insurance, established new regulations on health plans, created insurance pooling mechanisms and reduced Medicare spending on services provided by hospitals and other providers. Beginning on January 1, 2013, this legislation also imposed significant new taxes on medical device makers in the form of a 2.3% excise tax on U.S. medical device sales, as well as related compliance and reporting obligations. We currently estimate our medical device excise tax will be in the range of $6.5 million to $7.5 million for fiscal year 2015.

Moreover, the Physician Payment Sunshine Act (the Sunshine Act), which was enacted by Congress as part of the Patient Protection and Affordable Care Act on March 23, 2010, requires medical device companies to track and publicly report, with limited exceptions, all payments and transfers of value to physicians and teaching hospitals in the U.S. Implementing regulations for these tracking and reporting obligations were finalized in 2013, and companies are now required to track payments made since August 1, 2013. In addition, commencing March 31, 2014, medical device companies are now also required to report payments to the government on an annual basis. If we fail to comply with the data collection and reporting obligations imposed by the Sunshine Act, we may be subject to substantial civil monetary penalties.

In general, an expansion in the government’s role in the U.S. health care industry may lower reimbursements for our products, reduce demand for innovative products, reduce medical procedure volumes and adversely affect our business and results of operations, possibly in a material manner. In addition, as a result of the continued focus on health care reform, there is a risk that Congress may implement changes in laws and regulations governing health care service providers, including measures to control costs or reductions in reimbursement levels. We cannot predict the effect any future legislation or regulation will have on us or what health care initiatives, if any, will be implemented at the state level. Furthermore, many private payers look to Medicare’s coverage and reimbursement policies in setting their coverage policies and reimbursement amounts such that federal reforms could influence the private sector as well. Finally, many states also may attempt to reform their Medicaid programs such that either coverage for certain items or services may be narrowed or reimbursement for them could be reduced. These health care reforms may adversely affect our business.

Consistent with or in addition to Congressional or state reforms, CMS, the federal agency that administers the Medicare and Medicaid programs, could change its current policies that affect coverage and reimbursement for our products. CMS determined in 2007 that certain uses of pulse oximetry monitoring are eligible for separate Medicare payment in the hospital outpatient setting when no separately payable hospital outpatient services are reported on the same date of service. Each year, however, CMS re-examines the reimbursement rates for hospital inpatient and outpatient and physician office settings and could either increase or decrease the reimbursement rate for procedures utilizing our products. We are unable to predict when legislation or regulation that affects our business may be proposed or enacted in the future or what effect any such legislation or regulation would have on our business. Any such legislation, regulation or policies that affect the coverage and reimbursement of our current or future products, or the procedures utilizing our current or future products, could cause our sales to decrease and our revenue to decline.

Our success in international markets also may depend upon the eligibility of reimbursement for our products through government-sponsored health care payment systems and other third-party payers. Outside of the U.S., reimbursement systems vary by country. These systems are often subject to the same pressures to curb rising health care costs and control health care expenditures as those in the U.S. In addition, as economies of emerging markets develop, these countries may implement changes in their health care delivery and payment systems. If adequate levels of reimbursement from third-party payers outside of the U.S. are not obtained, sales of our products outside of the U.S. may be adversely affected.

Table of Contents

In addition, the requirements or restrictions imposed on us or our products may change, either as a result of administratively adopted policies or regulations or as a result of the enactment of new laws. Our medical devices and business activities are subject to rigorous regulation by the FDA and other federal, state and international governmental authorities. These authorities and members of Congress have been increasing their scrutiny over the medical device industry. In recent years, the U.S. Congress, Department of Justice, the Office of Inspector General of the Department of Health and Human Services, and the Department of Defense have issued subpoenas and other requests for information to medical device manufacturers, primarily related to financial arrangements with health care providers, regulatory compliance and marketing and product promotional practices. Furthermore, certain state governments have enacted legislation to increase transparency of interactions with health care providers, pursuant to which we are required by law to disclose payments and other transfers for value to health care providers licensed by certain states. We anticipate that the government will continue to scrutinize our industry closely, and any new regulations or statutory provisions could result in delays or increased costs during the periods of product development, clinical trials and regulatory review and approval, as well as increased costs to assure compliance.

Risks Related to Our Business and Operations

*We may experience conflicts of interest with Cercacor with respect to business opportunities and other matters.

Prior to our initial public offering in August 2007, our stockholders owned 99% of the outstanding shares of capital stock of Cercacor and we believe that, as of October 3, 2015 , a number of our stockholders, including certain of our directors and executive officers, continue to own shares of Cercacor stock. Joe Kiani, our Chairman and Chief Executive Officer, is also the Chairman and Chief Executive Officer of Cercacor.

Due to the interrelated nature of Cercacor with us, conflicts of interest will arise with respect to transactions involving business dealings between us and Cercacor, potential acquisitions of businesses or products and the development and ownership of technologies and products, the sale of products, markets and other matters in which our best interests and the best interests of our stockholders may conflict with the best interests of the stockholders of Cercacor. In addition, we and Cercacor may disagree regarding the interpretation of certain terms in the Cross-Licensing Agreement. We cannot guarantee that any conflict of interest will be resolved in our favor, or that, with respect to our transactions with Cercacor, we will negotiate terms that are as favorable to us as if such transactions were with another third-party.

*We will be required to assign to Cercacor and pay Cercacor for the right to use certain products and technologies we develop that relate to the monitoring of non-vital sign parameters, including improvements to Masimo SET ^® .

Under the Cross-Licensing Agreement, if we develop certain products or technologies that relate to the noninvasive monitoring of non-vital sign parameters, including improvements to Masimo SET ^® for the noninvasive monitoring of non-vital sign parameters, we would be required to assign these developments to Cercacor and then license the technology back from Cercacor in consideration for upfront payments and royalty obligations to Cercacor. Therefore, these products and technologies would be deemed to have been developed or improved exclusively by Cercacor. In addition, we will not be reimbursed by Cercacor for our expenses relating to the development or improvement of any such products or technologies, which expenses may be significant. As a result of these terms, we may not generate any revenue from the further development of certain products and technologies for the monitoring of non-vital sign parameters, including improvements to Masimo SET ^®, which could adversely affect our business, financial condition and results of operations.

*We are required to pay royalties to Cercacor for all products sold that contain certain rainbow ^® technologies, including certain annual minimum royalty payments, and this may impact our reported gross margins if we discontinue consolidating Cercacor within our financial statements.

The Cross-Licensing Agreement requires us to pay Cercacor a royalty for all products that we sell which include its proprietary rainbow ^® technology. This includes handheld, table-top and multi-parameter products that incorporate licensed rainbow ^® technology. Beginning in 2009, for hospital contracts where we place equipment and enter into a sensor contract, we pay a royalty to Cercacor on the total sensor contract revenue based on the ratio of rainbow ^® enabled devices to total devices. The agreement also requires that we make available to Cercacor, at its request, up to 10% of our annual board and sensor production volume at our total manufactured cost. In addition to these specific royalty and product obligations, our Cross-Licensing Agreement requires that we pay Cercacor specific annual minimum royalty payments.

Currently, we are required to consolidate Cercacor within our financial statements. Accordingly, the royalties that we owe to Cercacor are eliminated in our condensed consolidated financial statements presented within this Quarterly Report on Form 10-Q and our other periodic reports, and the gross profit margins reported in our consolidated financial results do not include the royalty expense that we pay to Cercacor. We are also obligated to include, and have included, Cercacor’s engineering and administrative expenses in our reported engineering and administrative expenses. If our financial statements were not

Table of Contents

consolidated with Cercacor, our reported cost of goods sold would increase and our reported engineering and administrative expenses would decrease. In the future, depending upon the success of rainbow ^® products and the royalties earned by Cercacor on those revenues, it is possible that the royalty expense will grow at a rate higher than the growth of engineering and administrative expenses. Should this occur, and if we also were no longer required to consolidate Cercacor’s financial results within our financial statements, our unconsolidated cost of goods sold could grow at a faster rate than that at which our unconsolidated engineering expenses decrease.

Despite describing and reflecting this Cercacor consolidation requirement within our financial statements, failure to understand or appreciate the significance of our consolidation of Cercacor’s financial statements may lead current and prospective investors to draw inaccurate perspectives and conclusions regarding our historical and future financial condition and results of operations.

In the event that the Cross-Licensing Agreement is terminated for any reason, or Cercacor grants a license to rainbow ^® technology to a third-party, our business would be materially and adversely affected.

Cercacor owns all of the proprietary rights to certain rainbow ^® technology developed with our proprietary Masimo SET ^® for products intended to be used in the Cercacor Market, and all rights to any non-vital signs measurement for which we do not exercise an option pursuant to the Cross-Licensing Agreement. In addition, Cercacor has the right to terminate the Cross-Licensing Agreement or grant licenses covering rainbow ^® technology to third parties if we breach certain terms of the agreement, including any failure to meet our minimum royalty payment obligations or failure to use commercially reasonable efforts to develop or market products incorporating licensed rainbow ^® technology. If we lose our exclusive license to rainbow ^® technology, we would lose the ability to prevent others from making, using, selling or importing products using rainbow ^® technology in our market. As a result, we would likely be subject to increased competition within our market, and Cercacor or competitors who obtain a license to rainbow ^® technology from Cercacor would be able to offer related products.

We may not be able to commercialize our products incorporating licensed rainbow ^® technology cost-effectively or successfully.

As a result of the royalties that we must pay to Cercacor, it is generally more expensive for us to make products that incorporate licensed rainbow ^® technology than products that do not include licensed rainbow ^® technology. We cannot assure you that we will be able to sell products incorporating licensed rainbow ^® technology at a price the market is willing to accept. If we cannot commercialize our products incorporating licensed rainbow ^® technology successfully, we may not be able to generate sufficient product revenue from these products to be profitable, which could adversely affect our business, financial condition and results of operations.

Rights provided to Cercacor in the Cross-Licensing Agreement may impede a change in control of our company.

Under the Cross-Licensing Agreement, a change in control includes the resignation or termination of Joe Kiani from his position as Chief Executive Officer of either Masimo or Cercacor. A change in control also includes other customary events, such as the sale or merger of our company or Cercacor to a non-affiliated third-party or the acquisition of 50% or more of the voting power of our company or Cercacor by a non-affiliated third-party. In the event we undergo a change in control, we are required to immediately pay a $2.5 million fee to exercise an option to license technology developed by Cercacor for use in blood glucose monitoring. Additionally, our per product royalties payable to Cercacor will become subject to specified minimums, and the minimum aggregate annual royalties for licensed rainbow ^® measurements payable to Cercacor related to carbon monoxide, methemoglobin, fractional arterial oxygen saturation, hemoglobin and blood glucose will increase to $15.0 million, plus up to $2.0 million for other rainbow ^® measurements. Also, if the surviving or acquiring entity ceases to use “Masimo” as a company name and trademark following a change in control, all rights to the “Masimo” trademark will automatically be assigned to Cercacor. This could delay or discourage transactions involving an actual or potential change in control of us, including transactions in which our stockholders might otherwise receive a premium for their shares over our then-current trading price. In addition, our requirement to assign all future improvements for non-vital signs to Cercacor could impede a change in control of our company.

We may experience significant fluctuations in our quarterly results in the future, we may not maintain our current levels of profitability, and changes to existing accounting pronouncements or taxation rules may affect how we conduct our business and our results of operations.

Our operating results have fluctuated in the past and are likely to fluctuate in the future. We may experience fluctuations in our quarterly results of operations as a result of:


•	delays or interruptions in manufacturing and shipping of our products;


•	varying demand for and market acceptance of our technologies and products;

Table of Contents


•	delayed acceptance of our new products, negatively impacting the carrying value of our inventory;


•	design, technology or other market changes that could negatively impact the carrying value of our inventory;


•	the effect of competing technological and market developments resulting in lower selling prices or significant promotional costs;


•	changes in the timing of product orders and the volume of sales to our OEM partners;


•	actions taken by GPOs;


•	delays in hospital conversions to our products and declines in hospital patient census;


•	our legal expenses, particularly those related to litigation matters;


•	changes in our product or customer mix;


•	movements in foreign currency exchange rates;


•	market seasonality of our sales due to quarterly fluctuations in hospital and other alternative care admissions;


•	our ability to renew existing long-term sensor contract commitments;


•	changes in the total dollar amount of annual contract renewal activities;


•	changes in the mix and, therefore, the related costs of products that we supply at no upfront costs to our customers as part of their long-term sensor commitments;


•	changes in hospital and other alternative care admission levels;


•	our inability to efficiently scale operations and establish processes to accommodate business growth;


•	unanticipated delays or problems in the introduction of new products, including delays in obtaining clearance or approval from the FDA;


•	high levels of returns and repairs; and


•	change in reimbursement rates for SpHb ^® , SpCO ^® and SpMet ^® parameters.

In addition, a change in accounting pronouncements or taxation rules or practices, or the interpretation of them by the SEC or other regulatory bodies, can have a significant effect on our reported results and may even affect our reporting of transactions completed before the change is effective. New accounting pronouncements or taxation rules and varying interpretations of accounting pronouncements or taxation practice have occurred and may occur in the future. Changes to existing rules, the adoption of new rules, changes in tax laws, or the expiration of existing favorable tax holidays may adversely affect our reported financial results or the way we conduct our business.

If our operating results fail to meet or exceed the expectations of securities analysts or investors, our stock price could drop suddenly and significantly. Our expense levels are based, in part, on our expectations regarding future revenue levels and are relatively fixed in the short term. As a result, if our revenue for a particular period was below our expectations, we would not be able to proportionately reduce our operating expenses for that period. Any revenue shortfall would have a disproportionately negative effect on our operating results for the period. Due to these and other factors, you should not rely on our results for any one quarter as an indication of our future performance.

Our results of operations could vary as a result of the methods, estimates and judgments that we use in applying our accounting policies.

The methods, estimates and judgments that we use in applying our accounting policies have a significant impact on our results of operations. Such methods, estimates and judgments are, by their nature, subject to substantial risks, uncertainties and assumptions and factors may arise over time that lead us to change our methods, estimates and judgments. Changes in those methods, estimates and judgments could significantly affect our results of operations. See “Critical Accounting Estimates” contained in Part II, Item 7 of our Annual Report on Form 10-K for the fiscal year ended January 3, 2015 , which we filed with the SEC on February 17, 2015 .

If we lose the services of our key personnel, or if we are unable to attract and retain other key personnel, we may not be able to manage our operations or meet our growth objectives.

We are highly dependent on our senior management, especially Joe Kiani, our Chief Executive Officer, and other key officers. We are also heavily dependent on our engineers and field sales team, including sales representatives and clinical specialists. Our success will depend on our ability to retain our current management, engineers and field sales team, and, in order to manage current operations and growth effectively, to attract and retain qualified personnel in the future, including scientists, clinicians, engineers and other highly skilled personnel. As competition for senior management, engineers and field sales

personnel is intense, we may not be able to retain our personnel. In addition, some of our key personnel hold stock options with an exercise price that is greater than our recent closing prices, which may minimize the retention value of these options. The loss of the services of members of our key personnel, or the inability to attract and retain qualified personnel in the future, could prevent the implementation and completion of our objectives, including the development and introduction of our products. In general, our key personnel may terminate their employment at any time and for any reason without notice.

Existing or future acquisitions of businesses could negatively affect our business, financial condition and results of operations if we fail to integrate the acquired businesses successfully into our existing operations or if we discover previously undisclosed liabilities.

We have acquired six businesses since our inception and we may acquire additional businesses in the future. Successful acquisitions depend upon our ability to identify, negotiate, complete and integrate suitable acquisitions and to obtain any necessary financing. Even if we complete acquisitions, we may experience:


•	difficulties in integrating any acquired companies, personnel, products and other assets into our existing business;


•	delays in realizing the benefits of the acquired company, products or other assets;


•	diversion of our management’s time and attention from other business concerns;


•	limited or no direct prior experience in new markets or countries we may enter;


•	higher costs of integration than we anticipated;


•	difficulties in retaining key employees of the acquired business who are necessary to manage these acquisitions; and


•	changes in the overall financial model as certain acquired companies may have a different revenue, gross profit margin or operating expense profile.

In addition, an acquisition could materially impair our operating results by causing us to incur debt or requiring us to amortize acquisition expenses and acquired assets. We may also discover deficiencies in internal controls, data adequacy and integrity, product quality, regulatory compliance and product liabilities that we did not uncover prior to our acquisition of such businesses, which could result in us becoming subject to penalties or other liabilities. Any difficulties in the integration of acquired businesses or unexpected penalties or liabilities in connection with such businesses could have a material adverse effect on our business, financial condition and results of operations.

*The risks inherent in operating internationally and the risks of selling and shipping our products and of purchasing our components and products internationally may adversely impact our business, financial condition and results of operations.

We derive a portion of our net sales from international operations. In the nine months ended October 3, 2015 and September 27, 2014 , 28.3% and 31.8% , respectively, of our product revenue was derived from our international operations. In addition, we purchase a portion of our raw materials and components on the international market. The sale and shipping of our products across international borders, as well as the purchase of materials and components from international sources, subject us to extensive U.S. and foreign governmental trade regulations. Compliance with such regulations is costly and we could be exposed to potentially significant penalties if we are found not to be in compliance with such regulations. Any failure to comply with applicable legal and regulatory obligations could impact us in a variety of ways that include, but are not limited to, significant criminal, civil and administrative penalties, including imprisonment of individuals, fines and penalties, denial of export privileges, seizure of shipments, restrictions on certain business activities, and exclusion or debarment from government contracting. Also, the failure to comply with applicable legal and regulatory obligations could result in the disruption of our shipping, manufacturing and sales activities. Any material decrease in our international sales would adversely affect our business, financial condition and results of operations.

In addition, our international sales operations expose us and our representatives, agents and distributors to risks inherent in operating in foreign jurisdictions. These risks include, but are not limited to:


•	the imposition of additional U.S. and foreign governmental controls or regulations;


•	the imposition of costly and lengthy new export licensing requirements;


•	a shortage of high-quality sales people and distributors;


•	loss of any key personnel that possess proprietary knowledge, or who are otherwise important to our success in certain international markets;


•	changes in duties and tariffs, license obligations and other non-tariff barriers to trade;

Table of Contents


•	the imposition of new trade restrictions;


•	the imposition of restrictions on the activities of foreign agents, representatives and distributors;


•	scrutiny of foreign tax authorities which could result in significant fines, penalties and additional taxes being imposed on us;


•	pricing pressure that we may experience internationally;


•	changes in foreign currency exchange rates;


•	laws and business practices favoring local companies;


•	political instability and actual or anticipated military or political conflicts;


•	financial and civil unrest worldwide;


•	longer payment cycles; and


•	difficulties in enforcing or defending intellectual property rights.

The U.S. Foreign Corrupt Practices Act and similar worldwide anti-bribery laws in non-U.S. jurisdictions generally prohibit companies and their intermediaries from promising or making improper payments to non-U.S. officials for the purpose of obtaining an advantage to secure or retain business. Because of the predominance of government-sponsored health care systems around the world, many of our customer relationships outside of the U.S. are with governmental entities and are therefore subject to such anti-bribery laws. Our policies mandate compliance with these anti-bribery laws. Despite our training and compliance programs, our internal control policies and procedures may not always protect us from reckless or criminal acts committed by our employees or agents. Violations of these laws, or allegations of such violations, could subject us to cash and non-cash penalties, disrupt our operations, involve significant management distraction and result in a material adverse effect on our business, financial condition and results of operations.

*Our operations may be adversely impacted by our exposure to risks related to foreign currency exchange rates.

We market our products in certain foreign markets through our subsidiaries and other international distributors. The related sales agreements may provide for payments in a foreign currency. While a majority of our sales are transacted in U.S. Dollars, some of our sales agreements with foreign customers provide for payment in currencies other than the U.S. Dollar. These foreign currency revenues, when converted into U.S. Dollars, can vary depending on average exchange rates during a respective period. Specifically, during the nine months ended October 3, 2015 , we estimate that the strengthening of the U.S. Dollar, relative to the Euro, Japanese Yen, Swedish Krona, Canadian Dollar, British Pound and Australian Dollar, negatively impacted our revenues by $14.5 million when compared to foreign exchange rates from the same prior year period. Similarly, certain of our foreign sales support subsidiaries transact business in their respective country’s local currency, which is also their functional currency. As a result, expenses of these foreign subsidiaries when converted into U.S. Dollars can vary depending on average monthly exchange rates during a respective period. We are also exposed to foreign currency gains or losses on outstanding foreign currency denominated receivables and payables. When converted to U.S. Dollars, these receivables and payables can vary depending on the monthly exchange rates at the end of the period. In addition, certain intercompany transactions may give rise to realized and unrealized foreign currency gains or losses based on the currency underlying such intercompany transactions. Accordingly, our operating results are subject to fluctuations in foreign currency exchange rates.

The balance sheets of our foreign subsidiaries whose functional currency is not the U.S. Dollar are translated into U.S. Dollars at the rate of exchange at the balance sheet date and the statements of comprehensive income and cash flows are translated into U.S. Dollars using the average monthly exchange rate during the period. Any foreign exchange gain or loss as a result of translating the balance sheets of our foreign subsidiaries whose functional currency is not the U.S. Dollar is included in equity as a component of accumulated other comprehensive income (loss).

We currently do not hedge our foreign currency exchange rate risk. Should we decide in the future to hedge such exchange rate risk by entering into forward contracts, these contracts may not mitigate the potential adverse impact on our financial results due to the variability of timing and amount of payments under these contracts. In addition, our failure to sufficiently hedge, forecast or otherwise manage such foreign currency risks properly could have a material adverse effect on our business, financial condition and results of operations.

We currently manufacture our products at several locations and any disruption to or expansion of our manufacturing operations could adversely affect our business, financial condition and results of operations.

We rely on our manufacturing facilities in Mexicali, Mexico; Irvine, California; Hudson, New Hampshire; and Danderyd, Sweden. These facilities and the manufacturing equipment we use to produce our products would be difficult to replace and could require substantial time to repair. Our facilities may be affected by natural or man-made disasters. Earthquakes are of

Table of Contents

particular significance since some of our facilities are located in an earthquake-prone area. We are also vulnerable to damage from other types of disasters, including power loss, attacks from extremist or terrorist organizations, epidemics, communication failures, fire, floods and similar events. In the event that one of our facilities was affected by a natural or man-made disaster, we would be forced to rely on third-party manufacturers if we could not shift production to our other manufacturing facilities. Furthermore, our insurance for damage to our property and the disruption of our business from casualties may not be sufficient to cover all of our potential losses and may not continue to be available to us on acceptable terms, or at all. If we are forced to seek alternative facilities, or if we voluntarily expand one or more of our manufacturing operations to new locations, we may incur additional transition costs and we may experience a disruption in the supply of our products until the new facilities are available and operating.

We also purchase materials and components from international sources. Any disruption in the supply of such materials, including transportation or port delays, could adversely impact our manufacturing operations. Disruptions may also occur as a result of local, regional and worldwide health risks. Such disruptions may include the inability to manufacture and distribute our products due to the direct effects of illness on individuals or due to constraints on supply and distribution that may result from either voluntary or government imposed restrictions.

Any disruption or delay at our manufacturing facilities, any expansion of our operations to additional locations, or any changes in market conditions could create operational hurdles and have an adverse impact on our ability to produce sufficient inventory of our products or may require us to incur additional expenses in order to produce sufficient inventory, depending on changes in product demand. Furthermore, if we are unable to meet the demand of our customers, our customers may cancel orders or purchase products from our competitors, which could adversely affect our business, financial condition and results of operations. Conversely, if product demand decreases, we may be unable to timely adjust our manufacturing cost structure, resulting in excess capacity, which would lower gross product margins. Similarly, if we are unable to forecast demand accurately, we could be required to record charges related to excess or obsolete inventory, which would also lower our gross margin.

Our suppliers may not supply us with a sufficient amount of materials and components or materials and components of adequate quality.

We depend on sole or limited source suppliers for key materials and components of our noninvasive blood constituent patient monitoring solutions, and if we are unable to obtain these components on a timely basis, we will not be able to deliver our noninvasive blood constituent patient monitoring solutions to customers. Also, we cannot guarantee that any of the materials or components that we purchase, if available at all, will be of adequate quality. From time to time, there are industry-wide shortages of several electronic components that we use in our noninvasive blood constituent patient monitoring solutions. We may experience delays in production of our products if we fail to identify alternate vendors for materials and components, or any parts supply is interrupted or reduced or there is a significant increase in production costs, each of which could adversely affect our business, financial condition and results of operations.

If we fail to comply with the reporting obligations of the Securities Exchange Act of 1934, as amended, and Section 404 of the Sarbanes-Oxley Act of 2002, as amended, or if we fail to maintain adequate internal control over financial reporting, our business, results of operations and financial condition and investors’ confidence in us could be materially and adversely affected.

As a public company, we are required to comply with the periodic reporting obligations of the Securities Exchange Act of 1934, as amended (the Exchange Act), including preparing annual reports, quarterly reports and current reports. Our failure to prepare and disclose this information in a timely manner and meet our reporting obligations in their entirety could subject us to penalties under federal securities laws and regulations of The NASDAQ Stock Market LLC, expose us to lawsuits and restrict our ability to access financing on favorable terms, or at all.

In addition, pursuant to Section 404 of the Sarbanes-Oxley Act of 2002, as amended (the Sarbanes-Oxley Act), we are required to evaluate and provide a management report on our systems of internal control over financial reporting, and our independent registered public accounting firm is required to attest to our internal control over financial reporting. During the course of the evaluation of our internal control over financial reporting, we may identify areas requiring improvement and may be required to design enhanced processes and controls to address issues identified through this review. This could result in significant delays and costs to us and require us to divert substantial resources, including management time, from other activities. In addition, if we fail to maintain the adequacy of our internal controls over financial reporting, we may not be able to ensure that we can conclude on an ongoing basis that we have effective internal control over financial reporting in accordance with the Sarbanes-Oxley Act. Moreover, effective internal controls are necessary for us to produce reliable financial reports and are important to help prevent fraud. Any failure to maintain compliance with the requirements of Section 404 of the Sarbanes-Oxley Act could result in the loss of investor confidence in the reliability of our financial statements, which in turn could harm our business,

Table of Contents

negatively impact the trading price of our stock, and adversely affect investors’ confidence in our company and our ability to access capital markets for financing.

*Changing laws and increasingly complex corporate governance and public disclosure requirements could have an adverse effect on our business and operating results.

Changing laws, regulations and standards relating to corporate governance and public disclosure, including the Sarbanes-Oxley Act, the Dodd-Frank Wall Street Reform and Consumer Protection Act (Dodd-Frank Act), the California Transparency in Supply Chains Act, the UK Modern Slavery Act and new regulations issued by the SEC and The NASDAQ Stock Market LLC, have and will create additional compliance requirements for companies such as ours. To maintain high standards of corporate governance and public disclosure, we have invested in, and intend to continue to invest in, reasonably necessary resources to comply with evolving standards.

For example, the Dodd-Frank Act includes provisions regarding “conflict minerals” (generally tin, tantalum, tungsten and gold) that are mined in the Democratic Republic of Congo and adjoining countries (the DRC region), and similar rules have been proposed in the European Union. Since certain of these conflict minerals are used in the manufacture of our products, the Dodd-Frank Act provisions require us to undertake comprehensive due diligence to determine whether conflict minerals used in our products, including any portion of our products manufactured by third parties, financed or benefited armed groups in the DRC region. The rules also require us to file conflict mineral reports with the SEC annually. We have incurred, and expect to continue to incur, additional costs to comply with these rules, including costs related to determining the source of origin of conflict minerals used in our products. Given the complexity of our supply chain, we may face difficulties if our suppliers are unwilling or unable to verify the origin of all conflict minerals used in our products. Furthermore, our ongoing compliance with these rules could affect the pricing, sourcing and availability of minerals used in the manufacture of our products. We may also encounter challenges with our customers and stockholders if we are unable to certify that our products are free of conflict minerals. To maintain high standards of corporate governance and public disclosure, we have invested in, and intend to continue to invest in, reasonably necessary resources to comply with such evolving standards. These investments have resulted in increased general and administrative expenses and a diversion of management time and attention from revenue-generating activities and may continue to do so in the future.

In addition, stockholder litigation surrounding executive compensation and disclosure of executive compensation has increased with the passage of the Dodd-Frank Act. Furthermore, in recent years, our stockholders have not approved our advisory vote on named executive officer compensation that is required to be voted on by our stockholders annually pursuant to the Dodd-Frank Act. If we are involved in a lawsuit related to compensation matters or any other matters not covered by our directors’ and officers’ liability insurance, we may incur significant expenses in defending against such lawsuits, or be subject to significant fines or required to take significant remedial actions, each of which could adversely affect our business, financial condition and results of operations.

If product liability claims are brought against us, we could face substantial liability and costs.

The manufacture and sale of products using Masimo SET ^® and licensed rainbow ^® technology expose us to product liability claims and product recalls, including, but not limited to, those that may arise from unauthorized off-label use, which is use of a device in a manner outside the measurement or measurements cleared by the FDA, malfunctions, design flaws or manufacturing defects related to our products or the use of our products with incompatible components or systems. For example, on April 21, 2014, an amended putative class action complaint was filed against us alleging product liability and negligence claims in connection with pulse oximeters that we modified and provided at the request of the study investigators for use in a randomized trial at the University of Alabama. The amended complaint seeks unspecified damages, costs, interest, attorney fees and injunctive and other relief. While we believe we have good and substantial defenses to the claims, there is no guarantee that we will prevail. In addition, we cannot be certain that our product liability insurance will be sufficient to cover any or all damages or claims asserted in this case or any other product liability claims that may be brought against us in the future. Furthermore, we may not be able to obtain or maintain insurance in the future at satisfactory rates or in adequate amounts to protect us against any product liability claims. Any losses that we may suffer from product liability claims, and the effect that any product liability litigation may have upon the reputation and marketability of our technology and products, together with the corresponding diversion of the attention of our key employees, may subject us to significant damages and could adversely affect our business, financial condition and results of operations.

We may incur environmental and personal injury liabilities related to certain hazardous materials used in our operations.

Our manufacturing processes involve the use, generation and disposal of certain hazardous materials and wastes, including silicone adhesives, solder and solder paste, sealants, epoxies and various solvents such as methyl ethyl ketone, acetone and isopropyl alcohol. As a result, we are subject to stringent federal, state and local laws relating to the protection of the

Table of Contents

environment, including those governing the use, handling and disposal of hazardous materials and wastes. We may incur significant costs to comply with environmental regulations.

Products that we sell in Europe are subject to regulation in the EU markets under the Restriction of the Use of Hazardous Substances Directive (RoHS). RoHS prohibits companies from selling products that contain certain hazardous materials, including lead, mercury, cadmium, chromium, polybrominated biphenyls and polybrominated diphenyl ethers, in EU member states. In addition, the EU’s Registration, Evaluation, Authorization, and Restriction of Chemicals Directive also restricts substances of very high concern in products. Complying with this regulation may result in significant product transition costs, including potential risk to the carrying value of the related inventory, or delays in sales of our products in the EU.

From time to time, new regulations are enacted and it is difficult to anticipate how such regulations will be implemented and enforced. We continue to evaluate the necessary steps for compliance with environmental regulations as they are enacted. Future environmental laws may significantly affect our operations by, for example, requiring our manufacturing processes to be altered or requiring us to use different types of materials in manufacturing our products. Any changes to our operations may increase our manufacturing costs, detrimentally impact the performance of our products, add greater testing lead-times for product introductions or have other similar effects. In our research and manufacturing activities, we use, and our employees may be exposed to, materials that are hazardous to human health, safety or the environment. These materials and various wastes resulting from their use are stored at our facility pending ultimate use and disposal. The risk of accidental injury to our employees or contamination from these materials cannot be eliminated. In the event of such an accident, we could be held liable for any resulting damages and any such liability could exceed our reserves. Although we maintain general liability insurance, we do not specifically insure against environmental liabilities. If an enforcement action were to occur, our reputation and our business and financial condition may be harmed, even if we were to prevail or settle the action on terms favorable to us.

We rely significantly on information technology and any failure, inadequacy, interruption or security lapse of that technology, including any cybersecurity incidents, could harm our ability to operate our business effectively.

Our ability to effectively manage and maintain our internal business information, and to ship products to customers and invoice them on a timely basis, depends significantly on our enterprise resource planning system and other information systems. Portions of our information technology systems may experience interruptions, delays or cessations of service or produce errors in connection with ongoing systems implementation work. Cybersecurity attacks in particular are evolving and include, but are not limited to, malicious software, attempts to gain unauthorized access to data and other electronic security breaches that could lead to disruptions in systems, misappropriation of our confidential or otherwise protected information and corruption of data. The failure of these systems to operate effectively or to integrate with other systems, or a breach in security or other unauthorized access of these systems, may also result in delays in product fulfillment and reduced efficiency of our operations, and could require significant capital investments to remediate any such failure, problem or breach, all of which could adversely affect our business, financial condition and results of operations.

Our operating results may be adversely affected by unfavorable economic and market conditions.

Many of the countries in which we operate, including the United States and several of the members of the EU, have experienced and continue to experience uncertain economic conditions. Our business or financial results may be adversely impacted by these uncertain economic conditions, including: adverse changes in interest rates, foreign currency exchange rates, tax laws or tax rates; inflation; contraction in the availability of credit in the marketplace due to legislation or other economic conditions, which may potentially impair our ability to access the capital markets on terms acceptable to us or at all; and the effects of government initiatives to manage economic conditions. In addition, we cannot predict how future economic conditions will affect our critical customers, suppliers and distributors and any negative impact on our critical customers, suppliers or distributors may also have an adverse impact on our results of operations or financial condition.

*Our Amended Credit Agreement contains certain covenants and restrictions that may limit our flexibility in operating our business.

Our Amended Credit Agreement with JPMorgan Chase Bank, N.A., as Administrative Agent and Lender, and Bank of America, N.A., as a Lender, contains various affirmative covenants and restrictions that limit our ability to engage in specified types of transactions, including:


•	incurring specified types of additional indebtedness (including guarantees or other contingent obligations);


•	paying dividends on, repurchasing, or making distributions in respect of our common stock or making other restricted payments, subject to specified exceptions;


•	making specified investments (including loans and advances);

Table of Contents


•	selling or transferring certain assets;


•	creating certain liens;


•	consolidating, merging, selling or otherwise disposing of all or substantially all of our assets; and


•	entering into certain transactions with any of our affiliates.

In addition, under our Amended Credit Agreement, we are required to satisfy and maintain specified financial ratios and other affirmative covenants. Our ability to meet those financial ratios and affirmative covenants could be affected by events beyond our control, and, therefore, we cannot be assured that we will be able to continue to satisfy these requirements. A breach of any of these ratios or covenants could result in a default under the Amended Credit Agreement. Upon the occurrence of an event of default, our lenders could elect to declare all amounts outstanding under our Amended Credit Agreement to be immediately due and payable, terminate all commitments to extend further credit and pursue legal remedies for recovery, all of which could adversely affect our business and financial condition. As of October 3, 2015 , we had $190.0 million outstanding under the Amended Credit Agreement and we were in compliance with all applicable covenants.

Risks Related to Our Stock

*Our stock price may be volatile, and your investment in our stock could suffer a decline in value.

There has been significant volatility in the market price and trading volume of equity securities, which is often unrelated to the financial performance of the companies issuing the securities. These broad market fluctuations may negatively affect the market price of our stock. From January 4, 2015 to October 3, 2015 , our closing stock price ranged from $25.52 to $43.61 per share. You may not be able to resell your shares at or above the price you paid for them due to fluctuations in the market price of our stock caused by changes in our operating performance or prospects and other factors.

In addition to the other risk factors previously discussed above, there are many other factors that we may not be able to control that could have a significant effect on our stock price. These include, but are not limited to:


•	actual or anticipated fluctuations in our operating results or future prospects;


•	our announcements or our competitors’ announcements of new products;


•	the public’s reaction to our press releases, our other public announcements and our filings with the SEC;


•	strategic actions by us or our competitors, such as acquisitions or restructurings;


•	new laws or regulations or new interpretations of existing laws or regulations applicable to our business;


•	changes in accounting standards, policies, guidance, interpretations or principles;


•	changes in our growth rates or our competitors’ growth rates;


•	developments regarding our patents or proprietary rights or those of our competitors;


•	ongoing legal proceedings;


•	our inability to raise additional capital as needed;


•	concerns or allegations as to the safety or efficacy of our products;


•	changes in financial markets or general economic conditions, including the effects of recession or slow economic growth in the U.S. and abroad;


•	sales of stock by us or members of our management team, our board of directors (Board) or certain institutional stockholders; and


•	changes in stock market analyst recommendations or earnings estimates regarding our stock, other comparable companies or our industry generally.

*Concentration of ownership among our existing directors, executive officers and principal stockholders may prevent new investors from influencing significant corporate decisions.

As of October 3, 2015 , our current directors and executive officers and their affiliates, in the aggregate, beneficially owned approximately 15.3% of our outstanding stock. Subject to any fiduciary duties owed to our other stockholders under Delaware law, these stockholders may be able to exercise significant influence over matters requiring stockholder approval, including the election of directors and approval of significant corporate transactions, and will have some control over our management and policies. Some of these persons or entities may have interests that are different from yours. For example, these stockholders

Table of Contents

may support proposals and actions with which you may disagree or which are not in your best interests. The concentration of ownership could delay or prevent a change in control of us, or otherwise discourage a potential acquirer from attempting to obtain control of us, which in turn could reduce the price of our stock. In addition, these stockholders could use their voting influence to maintain our existing management and directors in office or support or reject other management and Board proposals that are subject to stockholder approval, such as amendments to our employee stock plans and approvals of significant financing transactions.

*You could experience substantial dilution of your investment as a result of subsequent exercises of our outstanding options or the grant of future equity awards by us.

As of October 3, 2015 , an aggregate of approximately 14.5 million shares of our stock were reserved for future issuance under our three equity incentive plans, approximately 9.3 million of which were subject to options outstanding as of that date at a weighted-average exercise price of $25.04 per share. To the extent outstanding options are exercised, our existing stockholders may incur dilution. We rely on equity awards to motivate current employees and to attract new employees. The grant of future equity awards by us to our employees and other service providers may further dilute our stockholders.

Future resales of our stock, including those by our insiders and a few investment funds, may cause our stock price to decline.

A significant portion of our outstanding shares are held by our directors, our executive officers and a few investment funds. Resales by these stockholders of a substantial number of such shares, announcements of any proposed resale of substantial amounts of our stock or the perception that substantial resales may be made, could significantly reduce the market price of our stock. Some of our directors and executive officers have entered into Rule 10b5-1 trading plans pursuant to which they have arranged to sell shares of our stock from time to time in the future. Generally, these sales require public filings. Actual or potential sales by these insiders, including those under a pre-arranged Rule 10b5-1 trading plan, could be interpreted by the market as an indication that the insider has lost confidence in our stock and reduce the market price of our stock.

We have registered and expect to continue to register shares reserved under our equity plans pursuant to Registration Statements on Form S-8. All shares issued pursuant to a Registration Statement on Form S-8 can be freely sold in the public market upon issuance, subject to restrictions on our affiliates under Rule 144. If a large number of these shares are sold in the public market, the sales could reduce the trading price of our stock.

Our corporate documents and Delaware law contain provisions that could discourage, delay or prevent a change in control of our company, prevent attempts to replace or remove current management and reduce the market price of our stock.

Provisions in our amended and restated certificate of incorporation and amended and restated bylaws may discourage, delay or prevent a merger or acquisition involving us that our stockholders may consider favorable. For example, our amended and restated certificate of incorporation authorizes our Board to issue up to 5.0 million shares of “blank check” preferred stock. As a result, without further stockholder approval, our Board has the authority to attach special rights, including voting and dividend rights, to this preferred stock. With these rights, preferred stockholders could make it more difficult for a third-party to acquire us. In addition, our amended and restated certificate of incorporation provides for a staggered board of directors, whereby directors serve for three year terms, with one-third of the directors coming up for reelection each year. A staggered Board will make it more difficult for a third-party to obtain control of our Board through a proxy contest, which may be a necessary step in an acquisition of us that is not favored by our Board.

We are also subject to anti-takeover provisions under the Delaware General Corporation Law. Under these provisions, if anyone becomes an “interested stockholder,” we may not enter into a “business combination” with that person for three years without special approval, which could discourage a third-party from making a takeover offer and could delay or prevent a change in control of us. For purposes of these provisions, an “interested stockholder” generally means someone owning 15% or more of our outstanding voting stock or an affiliate of ours that owned 15% or more of our outstanding voting stock during the past three years, subject to certain exceptions as described in the Delaware General Corporation Law.

In addition, we have adopted a stockholder rights plan. Under our stockholder rights plan, if any person becomes the beneficial owner of 15% or more of the outstanding shares of our stock, subject to a number of exceptions set forth in the plan, all of our stockholders other than the acquiring person will receive a right to purchase shares of our stock at a price of $136.00 per share. Our stockholder rights plan could discourage a takeover attempt and make an unsolicited takeover of our company more difficult. As a result, without the approval of our Board, you may not have the opportunity to sell your shares to a potential acquirer of us at a premium over prevailing market prices. This could reduce the market price of our stock.

*We may elect not to declare cash dividends on our stock, may elect to only pay dividends on an infrequent or irregular basis, or may elect not to make any additional stock repurchases. As a result, any return on your investment may be limited to the value of our stock. In addition, the payment of any future dividends or the repurchase of our stock might limit our ability to pursue other growth opportunities .

Our Board may from time to time declare, and we may pay, dividends on our outstanding shares in the manner and upon the terms and conditions provided by law. However, we may elect to retain all future earnings for the operation and expansion of our business, rather than paying cash dividends on our stock. Any payment of cash dividends on our stock will be at the discretion of our Board and will depend upon our results of operations, earnings, capital requirements, financial condition, business prospects, contractual restrictions and other factors deemed relevant by our Board. In addition, under certain circumstances, our Amended Credit Agreement may limit or restrict our ability to pay cash dividends. In the event our Board declares any dividends, there is no assurance with respect to the amount, timing or frequency of any such dividends.

In February 2013, our Board authorized a stock repurchase program, whereby we may purchase up to 6.0 million shares of our common stock over a period of up to three years. In October 2014, our Board increased the number of shares authorized for repurchase under the program by 3.0 million shares, bringing the total number of shares authorized for repurchase under the program to 9.0 million shares. As of October 3, 2015 , all of the authorized 9.0 million shares had been repurchased under this stock repurchase program.

In September 2015, our Board authorized a new stock repurchase program, whereby we may purchase up to 5.0 million shares of our common stock over a period of up to three years. As of October 3, 2015 , 5.0 million shares remained authorized for repurchase under this program. Any repurchase of our common stock will be at the discretion of a committee comprised of our Chief Executive Officer and Chief Financial Officer, and will depend on several factors, including, but not limited to, results of operations, capital requirements, financial conditions, available capital from operations or other sources, and the market price of our common stock. Therefore, there is no assurance with respect to the amount, price or timing of any such repurchases. We may elect to retain all future earnings for the operation and expansion of our business, rather than repurchasing additional outstanding shares. In addition, under certain circumstances, our Amended Credit Agreement may limit or restrict our ability to repurchase our stock. In the event we pay dividends, or make any stock repurchases in the future, our ability to finance any material expansion of our business, including through acquisitions, investments or increased capital spending, or to fund our operations, may be limited. In addition, any repurchases we may make in the future may not prove to be at optimal prices. Our Board may modify or amend our stock repurchase program at any time at its discretion without stockholder approval.
