NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

NOTE 1. BASIS OF PRESENTATION AND PRINCIPLES OF CONSOLIDATION

The accompanying condensed consolidated financial statements of IDEXX Laboratories, Inc. and its subsidiaries have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the requirements of Regulation S-X, Rule 10-01 for financial statements required to be filed as a part of this Quarterly Report on Form 10-Q. Unless the context requires otherwise, references in this Quarterly Report on Form 10-Q to "IDEXX," the "Company," "we," "our" or "us" refer to IDEXX Laboratories, Inc. and its subsidiaries.

The accompanying condensed consolidated financial statements include the accounts of IDEXX Laboratories, Inc. and our wholly-owned and majority-owned subsidiaries. We do not have any variable interest entities for which we are the primary beneficiary. All intercompany transactions and balances have been eliminated in consolidation.

The accompanying condensed consolidated financial statements reflect, in the opinion of our management, all adjustments necessary for a fair statement of our financial position and results of operations. All such adjustments are of a recurring nature. The consolidated balance sheet data at December 31, 201 5 was derived from audited financial statements, but does not include all disclosures required by U.S. GAAP. The results of operations for the three and six months ended June 30 , 201 6 are not necessarily indicative of the results to be expected for the full year or any future period. These condensed consolidated financial statements should be read in conjunction with this Quarterly Report on Form 10- Q for the quarter ended June 30 , 201 6 and our Annual Report on Form 10-K for the year ended December 31, 201 5 (the “2015 Annual Report”) filed with the U.S. Securities and Exchange Commission (“SEC”).

For the six months ended June 30, 2016 , changes in stockholders’ equity included (i) changes in other comprehensive income reflected in the condensed consolidated statements of comprehensive incom e; (ii) changes in common stock and additional paid-in capital reflected in the condensed consolidated statements of cash flows (including share-based compensation expense, proceeds from exercise of stock option s and employee stock purchase plans, tax benefit from share-based compensation arrangements and repurchases of common stock); (iii) noncontrolling interest; and (iv) net income.

Reclassifications

Certain prior year amounts have been reclassified to conform with the c urrent year presentation. R eclassifications had no material impact on previously reported results of operations, financial position or cash flows.

Note 2. ACCOUNTING POLICIES

Significant Accounting Policies

T he significant accounting policies used in preparation of these condensed consolidated financial statements for the three and six months ended June 30 , 201 6 are consistent with those discussed in Note 2 to the consolidated financial statements in our 201 5 Annual Report, except as noted below.

New Accounting Pronouncements Adopted

Deferred Income Taxes

During the first quarter of 2016, the Company early adopted Financial Accounting Standards Board (“FASB”) amendments which require us to classify all deferred tax assets and liabilities as noncurrent within our condensed consolidated balance sheet. In accordance with the FASB’s permitted transition guidance, we applied this guidance prospectively and did not revise our prior period balance sheet pres entation for the effects of these amendment s . These amendments did not have a material impact on our financial statements.

Deferred Financing Costs

Effective January 1, 2016, the Company adopted FASB amendments that require debt issuance costs related to a recognized debt liability be presented within the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. This reclassification of the presentation of deferred financing costs did not have a material impact on other long-term assets or long-term debt amounts reported in our June 30 , 2016 condensed consolidated balance sheet and additionally would not have a material impact on such amounts reported in a prior period. As such, these amendments have been reflected prospectively in 2016; prior period amounts have not been revised for the effects of this amendment.

The FASB confirmed in August 2015 that the aforementioned amendments did not address the presentation or subsequent measurement of debt issuance costs related to line-of-credit arrangements. For line-of-credit arrangements, borrowers have the option of presenting debt issuance costs as an asset which is subsequently amortized ratably over the term of the line-of-credit arrangement, regardless of whether there are any related outstanding borrowings. As such, we continue to present deferred financing costs associated with our unsecured revolving credit facility within other long-term assets in the accompanying condensed consolidated balance sheets. Following recognition within the condensed consolidated balance sheets, all deferred financing costs are amortized to interest expense using the effective interest rate method over the term of the related debt agreement. These amendments did not have a material impact on our financial statements.

Additional Pronouncements

Dur ing the three and six months ended June 3 0 , 2016, the adoption of other effective FASB amendments addressing measurement-period adjustments for business combinations, accounting for cloud computing arrangements that include a software license, and to the fair value hierarchy of investments measured at net asset value did not have a material impact on our financial statements.

New Accounting Pronouncements Not Yet Adopted

In May 2014, the FASB issued an amendment which will replace most of the existing revenue recognition guidance within U.S. GAAP. The core principle of this guidance is that an entity should recognize revenue for the transfer of goods or services to customers in an amount that it expects to be entitled to receive for those goods or services. In doing so, companies will be required to make certain judgments and estimates, including identifying contract performance obligations, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price among separate performance obligations. Additionally, the amendment requires disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, significant judgments reached in the application of the guidance and assets recognized from the costs to obtain or fulfill a contract. In July 2015, the FASB voted to defer the effective date of the amendment to apply to public business entities for annual and interim periods ending after December 15, 2017. The amendment allows for two methods of adoption: a full retrospective method or a modified retrospective approach with the cumulative effect recognized at the date of initial application. We are in the process of determining the method of adoption and the impact of this amendment on our consolidated financial statements.

In August 2014, the FASB issued an amendment that requires management to assess an entity’s ability to continue as a going concern by incorporating and expanding upon certain principles that are currently in U.S. auditing standards. The amendment in this update provide s guidance about management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern for one year after the date that the financial statements are issued and to provide related footnote disclosures. In doing so, the amendment should reduce diversity in the timing and content of footnote disclosures. The amendment in this update applies to all entities and is effective for the annual period ending after December 15, 2016, and for annual periods and interim periods thereafter. Earl y application is permitted. This amendment is not expected to have a material impact on our financial statements.

In February 2015, the FASB issued amendments which change the analysis that a reporting entity must perform to determine whether it should consolidate certain types of legal entities, placing more emphasis on risk of loss when determining a controlling financial interest. The amendments in this update apply to all entities and are effective for the annual period ending after December 15, 2016, and for annual periods and interim periods thereafter. Earl y application is permitted. These amendment s are not expected to have a material impact on our financial statements.

In July 2015, the FASB issued amendments which simplify the existing guidance which requires entities to subsequently measure inventory at the lower of cost or market value. Under the amendments, an entity should measure inventory valued using a first-in, first-out or average cost method at the lower of cost or net realizable value, which is defined as the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, di sposal, and transportation. This update is effective for public business entities during fiscal years beginning after December 15, 2016. Early adoption is permitted. Th ese amendment s are not expected to have a material impact on our financial statements.

In February 2016, the FASB issued amendments to increase transparency and comparability among organizations’ leasing arrangements. The principal difference from previous guidance is that effective upon adoption, the lease assets and lease liabilities arising from operating leases will be recognized in the statement of financial position. For public business entities, the amendments in this update are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. In transition, we are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach, including the option to utilize a number of practical expedients. We are in the process of evaluating our lessee and lessor arrangements to determin e the impact of this amendment on our consolidated financial statements.

In March 2016, the FASB issued amendments which simplify several aspects of the accounting for share-based payment transactions, including income tax consequences, recognition of stock compensation award forfeitures, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The most significant change resulting from these amendments is recording all the tax effects related to share-based payments at settlement through the income statement. Under existing guidance, tax benefits in excess of compensation costs (“windfalls”) are recorded in equity. Similarly, tax deficiencies below compensation costs (“shortfalls”) are recorded in equity to the extent of previous windfalls, while shortfalls in excess of this are recorded to the income statement. For public business entities, this update is effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods. Early adoption is permitted for any entity in any interim or annual period. If an entity early adopts the amendments in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. An entity that elects early adoption must adopt all of the amendments in the same period. We are in the process of determining the method of adoption and the impact of th ese amendment s on our consolidated financial statements.

In June 2016, the FASB issued amendments that requires financial assets measured at amortized cost be presented at the net amount expected to be collected. The allowance for credit losses is a valuation account that is deducted from the amortized cost basis of the financial asset to present the net carrying value at the amount expected to be collected . The income statement reflects the measurement of credit losses for newly recognized financial assets, as well as the increases or decreases of expected credit losses that have taken place during the period. The measurement of expected credit losses is based upon historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. Credit losses relating to available-for-sale debt securities will be recorded through an allowance for credit losses rather than as a direct write-down to the security. The update requires consideration of a broader range of reasonable and supportable information and is intended to provide financial statement users with more useful information about expected credit losses. For public business entities, the amendments in this update are effective for fiscal years beginning after December 15, 2019 and interim periods within those annual periods. Early adoption for fiscal year beginning after December 15, 2018 is permitted. Entities will apply the standard’s provisions as a cumulative-effect adjustment to retained earnings as of the beginning of the first effective reporting period. We are in the process o f determining the impact of these amendment s on our consolidated financial statements.

NOTE 3 . SHARE-BASED COMPENSATION

The fair value of options, restricted stock units, deferred stock units and employee stock purchase rights awarded during the three and six months ended June 30, 2016 totaled $1.7 million and $25.7 million, respectively , as compared to $1.8 million and $23.8 million for the three and six months ended June 30, 2015 . T he total unrecognized compensation expense, net of estimated forfeitures, for unvested share-based compensatio n awards outstanding at June 30, 2016 was $50.5 million, which will be recognized over a weighted average period of approximately 2.1 years .

We determine the assumptions used in the valuation of option awards as of the date of grant. Differences in the expected stock price volatility, expected term or risk-free interest rate may necessitate distinct valuation assumptions at each grant date. As such, we may use different assumptions for options granted throughout the year. Option awards are granted with an exercise price equal to the closing market price of our common stock at the date of grant. We have never paid any cash dividends on our common stock, and we have no intention to pay such a dividend at this time; therefore, we assume that no dividends will be paid over the expected terms of option awards.

The weighted averages of the valuation assumptions used to determine the fair value of each option award on the date of grant and the weighted average estimated fair values were as follows:


	For the Six Months Ended
	June 30,
		2016			2015

Note 6 . Goodwill and Intangible Assets, NET

The increase in goodwill during the six months ended Ju n e 30, 2016 resulted from changes in foreign currency exchange rates. The decrease in intangible assets other than goodwill during the s i x months ended Ju n e 30, 2016 resulted primarily from the continued amortization of our intangible assets and an impairment charge related to our OPTI ® Medical line of business, partly offset by changes in foreign currency exchange rates.

During the first half of 2016, management reviewed the OPT I Medical product offerings. As a result of this review, we discontinued our product development activities in the human point-of-care medical diagnostics market during March 2016 and focus ed our commercial efforts in this market on supporting our latest generation OPTI CCA-TS2 Blood Gas and Electrolyte Analyzer . Management identified unfavorable trends in our OPTI Medical line of business resulting from this change in strategy. We revised our forecast s downward, causing us to assess the realizability of the related tangible and intangible assets and determined the expected future cash flows were less than the carrying value of the OPTI Medical asset group. N on-cash intangible asset impairment s of $2.2 million w ere recorded within our condensed consolidated statement of operations for the six months ended June 30, 2016. As of June 30, 2016, the intangibles associated with our human point-of-care medical diagno stics market were fully written off .

Note 9 . Repurchases of common STOCK

We primarily acquire shares by repurchases in the open market. However, we also acquire shares tha t are surrendered by employees in payment for the minimum required withholding taxes due on the vesting of restricted stock units and the settlement of deferred stock units, otherwise referred to herein as employee surrenders.

We issue shares of treasury stock upon the vesting of certain restricted stock units and upon the exercise of certain stock options. The number of shares of treasury st ock issued during both the three and six months ended June 30, 2016 and 201 5 was not material.

The following is a summary of our open market common stock repurchases , reported on a trade date basis, and shares acquired through employee surrender for the three and six months ended June 30 , 201 6 and 201 5 (in thousands, except per share amounts) :


	For the Three Months Ended				For the Six Months Ended

_____________

(1)

Shares repurchased and acquired through employee surrender for payment of minimum required withholding taxes on and before June 15, 2015 and the associated average cost per share have been adjusted to reflect the June 15, 2015 two -for-one stock split. Actual shares repurchased were approximately 890,000 for the three months ended June 30, 2015 and 1,749,000 for the six months ended June 30, 2015.

Note 10 . Income Taxes

Our effective income tax rate was 30.6% for both the three and six months ended June 3 0 , 2016, as compared to 30.2% and 30.3% for the three and six months ended June 30, 2015, respectively. The increase in our effective rate for the three and six months ended June 30, 2016, as compared to the same periods of the prior year, was primarily related to an earnings mix, with relatively higher earnings subject to domestic tax rates as opposed to lower international tax rates, including the impact of foreign currency exchange rates. This increase in effective tax rates, period over period, was mostly offset by the U.S. R&D tax credit. There was no available R&D tax credit during the period ending June 30, 2015 because the credit had not yet been extended. In December 2015, the R&D tax credit was permanently extended with retroactive application to January 1, 2015. As a result, we fully recognized the related 2015 tax benefit entirely in the fourth quarter of 2015.

Note 1 2 . Earnings per Share

Basic earnings per share is computed by dividing net income attributable to IDEXX Laboratories, Inc. stockholders by the weighted average number of shares of common stock and vested deferred stock units outstanding during the year. The computation of diluted earnings per share is similar to the computation of basic earnings per share, except that the denominator is increased for the assumed exercise of dilutive options and assumed issuance of unvested restricted stock units and unvested deferred stock units using the treasury stock method unless the effect is anti-dilutive. The treasury stock method assumes that proceeds, including cash received from the exercise of employee stock options, the total unrecognized compensation expense for unvested share-based compensation awards and the tax benefits resulting from share-based compensation tax deductions in excess of the related expense recognized for financial reporting purposes, would be used to purchase our common stock at the average market price during the period. Vested deferred stock units outstanding are included in shares outstanding for basic and diluted earnings per share because the associated shares of our common stock are issuable for no cash consideration, the number of shares of our common stock to be issued is fixed and issuance is not contingent. See Note 4 to the consolidated financial statements in our 201 5 Annual Report for additional information regarding deferred stock units.

The following is a reconciliation of weighted average shares outstanding for basic and diluted earnings per share for the three and six months ended June 30 , 201 6 and 201 5 (in thousands) :


	For the Three Months Ended		For the Six Months Ended
	June 30,		June 30,
	2016	2015	2016	2015

Shares outstanding for basic earnings per share	89,824	93,384	89,874	93,829

Shares outstanding for diluted earnings per share:
Shares outstanding for basic earnings per share	89,824	93,384	89,874	93,829
Dilutive effect of share-based payment awards	993	922	984	1,105
	90,817	94,306	90,858	94,934

C ertain options to acquire shares and restricted stock units have been excluded from the calculation of shares outstanding for diluted earnings per share because they were anti-dilutive. The following table presents information concerning those anti-dilutive options and restricted stock units for the three and six months ended June 3 0 , 201 6 and 2015 (in thousands ):


	For the Three Months Ended		For the Six Months Ended

Note 1 3 . Commitments, Contingencies and Guarantees

Significant commitments, contingencies and guarantees at June 3 0 , 201 6 are consistent with those discussed in Note 1 4 to the consolidated financial statements in our 201 5 Annual Report .

Note 1 4 . Segment Reporting

Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision-maker (“CODM”) , or decision-making group, in deciding how to allocate resources and in assessing performance. Our CODM is our Chief Executive Officer. Our reportable segments include diagnostic and information technology-based products and services for the veterinary market, which we refer to as the Companion Animal Group (“CAG”), water quality produc ts (“Water”) and diagnostic product s and services for livestock and poultry health and to ensure the quality and safety of milk and food, which we refer to as Livestock, Poultry and Dairy (“LPD”). Our Other operating segment combines and presents products for the human point-of-care medical diagnostics market with our pharmaceutical product line and our out-licensing arrangements because they do not meet the quantitative or qualitative thresholds for reportable segments.

Certain costs are not allocated to our operating segments and are instead reported under the caption “Unallocated Amounts”. These costs include costs that do not align with one of our existing operating segments or are cost prohibitive to allocate, which primarily consist of our R&D function, regional or country expenses, certain foreign currency revaluation gains and losses on monetary balances in currencies other than our subsidiaries’ functional currency and unusual items. Corporate support function costs (such as information technology, facilities, human resources, finance and legal), health benefits and incentive compensation are charged to our business segments at pre-determined budgeted amounts or rates. Differences from these pre-determined budgeted amounts or rates are captured within Unallocated Amounts.

Effective January 1, 2016, we modified our management reporting to the CODM to provide a more comprehensive view of the performance of our operating segments by including the capitalization of variances between standard and actual manufacturing costs, which adjusts the timing of cost recognition from when the variance is created to the period in which the related inventory is sold. Prior to January 1, 2016, the capitalization and subsequent recognition of these variances were not allocated to our operating segments and were instead reported under the caption “Unallocated Amounts”.

Note 15 . FAIR VALUE MEASUREMENTS

U.S. GAAP defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. U.S. GAAP requires an entity to maximize the use of observable inputs, where available, and minimize the use of unobservable inputs when measuring fair value.

The Company has certain financial assets and liabilities that are measured at fair value on a recurring basis, certain nonfinancial assets and liabilities that may be measured at fair value on a nonrecurring basis and certain financial assets and liabilities that are not measured at fair value in our condensed consolidated balance sheets but for which we disclose the fair value. The fair value disclosures of these assets and liabilities are based on a three-level hierarchy, which is defined as follows :

Level 1	Quoted prices in active markets for identical assets or liabilities that the entity can access at the measurement date.
Level 2	Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or 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.

Assets and liabilities measured at fair value are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. Our assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability. We did not have any transfers between Level 1 and Level 2 or transfers in or out of Level 3 of the fair value hierarchy during the six months ended June 30, 2016.

Our marketable debt securities are initially valued at the transaction price and are subsequently remeasured to fair value as of the balance sheet date utilizing third- party pricing services. The pricing services utilize industry standard valuation models, i ncluding both income and market- based approaches and observable market inputs to determine value. Observable market inputs include reportable trades, benchmark yields, credit spreads, broker/dealer quotes, bids, offers and other industry and economic events. We validate t he prices provided by our third- party pricing services by obtaining independent market values from other pricing sources and analyzing pricing data in certain instances.

Our foreign currency exchange contracts and interest rate swap agreements are measured at fair value on a recurring basis in our accompanying condensed consolidated balance sheets. We measure the fair value of our foreign currency exchange contracts classified as derivative instruments using an income approach, based on prevailing market forward rates less the contract rate multiplied by the notional amount. The product of this calculation is then adjusted for counterparty risk.

At December 31, 2015, w e measure d the fair value of our interest rate swaps classified as derivative instruments using an income approach, utilizing a discounted cash flow analysis based on the terms of the contract and the interest rate curve adjusted for counterparty risk. As of June 30, 2016, we have no outstanding interest rate swap agreements.

The amount s outstanding under our unsecured revolving credit facility (“Credit Facility” or “line of credit” ) and senior notes (“long-term debt”) are measured at carrying value in our accompanying condensed consolidated balance sheets though we disclose the fair value of these financial instruments. We determine the fair value of the amount outstanding under our Credit Facility and long-term debt using an income approach, utilizing a discounted cash flow analysis based on current market interest rates for debt issues with similar remaining years to maturity, adjusted for applicable credit risk. Our Credit Facility and l ong-term debt are valued using L evel 2 inputs. The estimated fair value of o ur Credit Facility approximates its carrying value. The estimated fair value and carrying value of our long-term debt were $635.1 million and $ 598.5 million , respectively, as of June 30, 2016, and $593.7 million and $597.1 million , respectively, as of December 31, 201 5 .

The following tables set forth our assets and liabilities that were measured at fair val ue on a recurring basis at June 30 , 201 6 and at December 31, 201 5 by level within the fair value hierarchy (in thousands) :

Note 1 6 . HEDGING Instruments

Disclosure within this note is presented to provide transparency about how and why we use derivative and non-derivative instruments (collectively “hedging instruments”) , how the instruments and related hedged items are accounted for, and how the instruments and related hedged items affect our financial position, results of operations and cash flows.

We are exposed to certain risks related to our ongoing business operations. The primary risks that we manage by using hedging instruments are foreign currency exchange risk and interest rate risk. Our subsidiaries enter into foreign currency exchange contracts to manage the exchange risk associated with their forecasted intercompany inventory purchases and sales for the next year. From time to time, we may also enter into other foreign currency exchange contracts or foreign-denominated debt issuances to minimize the impact of foreign currency fluctuations associated with specific balance sheet exposures , including net investments in certain foreign subsidiaries. We enter into interest rate swaps to minimize the impact of interest rate fluctuations associated with borrowings under our variable-rate Credit Facility.

The primary purpose of our foreign currency hedging activities is to protect against the volatility associated with foreign currency transactions, including transactions denominated in euro, British pound, Japanese yen, Canadian dollar, Australian dollar and Swiss franc. We also utilize natural hedges to mitigate our transaction and commitment exposures. Our corporate policy prescribes the range of allowable hedging activity. We enter into foreign curre ncy exchange contracts with well-capitalized multinational financial institutions, and we do not hold or engage in t ransactions involving hedging instruments for purposes other than risk management. Our accounting policies for these contracts are based on the designation of such instruments as hedging transactions.

We recognize all hedging instruments on the balance sheet at fair value at the balance sheet date. I nstruments that do not qualify for hedge accounting treatment must be recorded at fair value through earnings. To qualify for hedge accounting treatment, cash flow and net investment hedges must be highly effective in offsetting changes to expected future cas h flows or fair value on hedged transactions. If the instrument qualifies for hedge accounting, c hanges in the fair value of the hedging instrument from the effective portion of the hedge are deferred in AOCI, net of tax, and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. We immediately record in earn ings the extent to which a hedging instrument is not effective in achieving offsetting changes in fair value. We de-designate hedging instruments from hedge accounting when the likelihood of the hedged transaction occurring becomes less than probable. For de-designated instruments, the gain or loss from the time of de-designation through maturity of the instrument is recognized in earnings. Any gain or loss in AOCI at the time of de-designation is reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. See Note 11 to the condensed consolidated financial statements included in this Quarterly Report on Form 10-Q for further information regarding the effect of hedging instruments on the condensed consolidated statements of operations for the three and six months ended June 30, 2016 and 2015.

We enter into master netting arrangements with the counterparties to our derivative transactions which permit certain outstanding receivables and payables to be offset in the event of default. Our derivative contracts do not require either party to post cash collateral. We elect to present our derivative assets and liabilities in the accompanying condensed consolidated balance sheets on a gross basis. All cash flows related to our foreign currency exchange contracts and interest rate swaps are classified as operating cash flows, which is consistent with the cash flow treatment of the underlying items being hedged.

Cash Flow Hedges

We have designated our foreign currency exchange contracts and variable-to-fixed interest rate swaps as cash flow hedges as these derivative instruments mitigate the exposure to variability in the cash flows of forecasted transactions attributable to foreign currency exchange and interest rates. Unless noted otherwise, we have also designated our derivative instruments as qualifying for hedge accounting treatment.

We did not de-designate any instruments from hedge accounting treatment during the three and six months ended June 30, 2016 or 2015. Gains or losses related to hedge ineffectiveness recognized in earnings during the three and six months ended June 30, 2016 and 2015 were not material . At June 30, 2016, the estimated amount of net gains, net of income tax expense , which are expected to be reclassified out of AOCI and into earnings within the next 12 months, is $0.4 million if exchange and interest rates do not fluctuate from the levels at June 30, 2016.

W e hedge approximately 8 5% of the estimated exposure from intercompany product purchases and sales denominated in the euro, British pound, Canadian dollar, Japanese yen, Australian dollar and Swiss franc. We have additional unhedged foreign currency exposures related to foreign services and emerging markets where it is not practical to hedge. We primarily utilize foreign currency exchange contracts with durations of less than 24 months. Quarterly, we enter into contracts to hedge incremental portions of anticipated foreign currency transactions for the current and following year. As a result, our risk with respect to foreign currency exchange rate fluctuations and the notional value of foreign currency exchange contracts may vary throughout the year. The U.S. dollar is the currency purchased or sold in all of our foreign currency exchange contracts. The notional amount of foreign currency exchange contracts to hedge forecasted intercompany inventory purchases and sales totaled $163.2 million and $176.1 million at June 30, 2016 and December 31, 2015, respectively.

We had entered into forward fixed interest rate swap agreements to manage the economic effect of variable interest obligations on amounts borrowed under the terms of our Credit Facility. From March 30, 2012 to June 30, 2016 , the variable interest rate associated with $40 million of borrowings outstanding under the Credit Facility was effectively fixed at 1.36% plus the ra nge of applicable interest rate fixed credit spreads (“Credit Spread”) . From March 28, 2013 to June 30, 2016 , the variable interest rate associated with an additional $40 million of borrowings outstanding under the Credit Facility was effectively fixed at 1.64% plus the Credit Spread. As of June 30, 2016, we have no outstanding interest rate swap agreements.

Net Investment Hedge

In June 2015, we issued and sold through a private placement an aggregate principal amount of €88.9 million (approximately $100 million) in euro-denominated 1.785% Series C Senior Notes due June 18, 2025. We have designated these euro-denominated notes as a hedge of our euro net investment in certain foreign subsidiaries to reduce the volatility in stockholders’ equity caused by changes in foreign currency exchange rates in the euro relative to the U.S. dollar. As a result of this designation, gains and losses from the change in translated U.S. dollar value of these euro-denominated notes are recorded in AOCI rather than to earnings. We recorded a $1. 3 million gain and a $0.9 million loss , net of income tax, within AOCI as a result of this net investm ent hedge for the three and six months ended J une 30, 2016, respectively. The related cumulative unrealized gain recorded at June 30, 2016 will not be reclassified in earnings until the complete or substantially complete liquidation of the net investment in the hedg ed foreign operations or a portion of the hedge no longer qualifies for hedge accounting treatment. See Note 11 to the consolidated financial statements included in our 2015 Annual Report for further information regarding the issuance of these euro-denominated notes.

Business Overview

Operating Segments . We operate primarily through three business segments: diagnostic and information technology-based products and services for the veterinary market, which we refer to as the Companion Animal Group (“CAG”), water quality products (“Water”) and diagnostic products and services for livestock and poultry health and to ensure the quality and safety of milk and food, which we refer to as Livestock, Poultry and Dairy (“LPD”). Our Other oper ating segment combines and pres ents products for the human point-of-care medical diagnostics market (“ OPTI Medical”) with our pharmaceutical product line and our out-licensing arrangements because they do not meet the quantitative or qualitative thresholds for reportable segments.

CAG develops, designs, manufactures and distributes products and performs services for veterinarians and the bioresearch market, primarily related to diagnostics and information management. Water develops, designs, manufactures and distributes a range of products used in the detection of various microbiological parameters in water. LPD develops, designs, manufactures and distributes diagnostic tests and related instrumentation and performs services that are used to manage the health status of livestock and poultry, to improve bovine reproductive efficiency, and to ensure the quality and safety of milk and food. OPTI Medical manufactures and distributes point-of-care electrolyte and blood gas analyzers and related consumable products for the human medical diagnostics market.

During the second quarter of 2016, we renamed our customer information management and diagnostic imaging systems line of business in the CAG segment to veterinary software, services and diagnostic imaging systems. Financial results were not adjusted as a result of this name change.

Effective January 1, 2016, we modified our management reporting to the Chief Operating Decision Maker to provide a more comprehensive view of the performance of our operating segments by including the capitalization of variances between standard and actual manufacturing costs, which adjusts the timing of cost recognition from when the variance is created to the period in which the related inventory is sold. Prior to January 1, 2016, the capitalization and subsequent recognition of these variances were not allocated to our operating segments and were instead reported under the caption “Unallocated Amounts”.

The segment gross profit and income (loss) from operations within this Quarterly Report on Form 10-Q for the three and six months ended June 30, 2015 has been retrospectively revised to reflect the changes to our segment performance metrics described above. The following is a summary of restated segment gross profit from operations for the three and six months ended June 30, 2015:

Effects of Certain Factors and Trends on Results of Operations

Distributor Purchasing and Inventories . We employ an all-di rect sales strategy in the U.S.; however we continue to sell our products through third party distri butors in certain markets. When selling our products through distributors, changes in distributors’ inventory levels can impact our reported sales, and these changes may be affected by many factors, which may not be directly related to underlying demand for our products by veterinary practices, which are the end-users. W e do not believe the impact of changes in these distributors’ inventories had or would have a material impact on our growth rates in the relevant periods.

Currency Impact . For the three and six months ended June 30, 2016 , approximately 29 % and 28%, respectively, of our consolidated revenue was derived from products manufactured in the U.S. and sold internationally in l ocal currencies, as compared to 25% for both the three and six months ended June 30, 2015 . Strengthening of the U.S. dollar exchange rate relative to other currencies has a negative impact on our revenues derived in currencies other than the U.S. dollar and on profits of products manufactured in the U.S. and sold internationally, and a weakening of the U.S. dollar has the opposite effect. Similarly, to the extent that the U.S. dollar is stronger in current or future periods relative to the exchange rates in effect in the corresponding prior periods, our growth rate will be negatively affected. The impact of foreign currency denominated operating expenses and foreign currency denominated supply contracts partly offsets this exposure. Additionally, our designated hedges of intercompany inventory purchases and sales help delay the impact of certain exchange rate fluctuations on non-U.S. denominated revenues. See “Part II, Item 7A. Quantitative and Qualitative Disclosure About Market Risks” included in our 2015 Annual Report for additional information regarding currency impact. Our future income tax expense could also be affected by changes in the mix of earnings, including as a result of changes in the rate of exchange for the U.S. dollar relative to currencies in countries with differing statutory tax rates. See “Part I, Item 1A. Risk Factors” included in our 2015 Annual Report for additional information regarding tax impacts.

Our foreign currency exchange impacts are comprised of three components: 1) revenues and expenses denominated in a foreign currency; 2) the impact of hedge contracts; and 3) intercompany and monetary balances for our subsidiaries that are denominated in a currency that is different from the functional currency used by each subsidiary. As of June 30, 2016, based on projected revenues and expenses, excluding the impact of intercompany and trade balances denominated in currencies other than the functional subsidiary currencies, we estimate a 10% strengthening of the U.S. dollar would reduce operating income for the remainder of 2016 by approximately $6 million. The impact of the intercompany and monetary balances referred to in the third component above have been excluded, as they are transacted at multiple times during the year and we are not able to reliably forecast the impact that changes in exchange rates would have on our operating income.

The impact on revenue resulting from changes in foreign currency exchange rates is not a measure defined by accounting principles generally accepted in the United States of America (“U.S. GAAP”), otherwise referred to herein as a non-GAAP financial measure. We calculate the impact on revenue resulting from changes in foreign currency exchange rates by applying the difference between the weighted average exchange rates during the current year pe riod and the comparable prior year period applied to foreign currency denominated revenues for the prior year period. As exchange rates are an important factor in understanding period-to-period comparisons, we believe the presentation of results normalized for changes in currency in addition to reported results helps improve investors’ ability to understand our operating results and evaluate our performance in comparison to prior periods.

During the three and six months ended June 30, 2016, as compared to the same period of the prior year, changes in foreign currency exchange rates decreased total company revenue by approximately $2.8 million and $10.4 million respectively, due primarily to the strengthening of the U.S. dollar against the British pound and Canadian dollar. Foreign currency hedging gains did not have a significant impact on total company operating income and diluted earnings per share for the three months ended June 30, 2016 and increased total company operating income by $0.9 million and diluted earnings per share $0.01 during the six months ended June 30, 2016. During the same periods of the prior year, foreign currency hedging gains increased total company operating income by $5.1 and $9.5 million and diluted earnings per share by $0.04 and $0.07, respectively. Net of these lower relative foreign currency hedging gains, changes in foreign currency exchange rates reduced total company operating income by $7.2 million and diluted earnings per share by $0.06 during the three months ended June 30, 2016 and reduced total company operating income by $13.3 million and diluted earnings per share by $0.11 during the six months ended June 30, 2016.

At our current currency exchange rate assumptions as compared to actual 2015 exchange rates, we anticipate that the strengthening of the U.S. dollar relative to major foreign currencies in which we transact will decrease total company revenue by approximately $13.0 million for the full year ending December 31, 2016. Foreign currency hedging gains are expected to increase total company operating income by $4.0 million and diluted earnings per share by $0.03 in the year ending December 31, 2016 as compared to a total company operating income increase of $21.2 million and a $0.16 increase in diluted earnings per share in the year ended December 31, 2015. Net of these lower relative foreign currency hedging gains, changes in foreign currency exchange rates are expected to reduce total company operating income by $23.4 million and diluted earnings per share by $0.20. The above estimate incorporates actual exchange rates for the six months ended June 30, 2016 and assumes that the value of the U.S. dollar relative to other currencies will reflect the euro at $1.10, the British pound at $1.30, the Canadian dollar at $0.77, the Australian dollar at $0.75 and the Japanese yen at ¥104 to the U.S. dollar for the remainder of 2016.

Effects of Economic Conditions . Demand for our products and services is vulnerable to changes in the economic environment, including slow economic growth, high unemployment and credit availability. Negative or cautious consumer sentiment can lead to reduced or delayed consumer spending, resulting in a decreased number of patient visits to veterinary clinics. Unfavorable economic conditions can impact sales of instruments and diagnostic imaging systems, which are larger capital purchases for veterinarians . Additionally, economic turmoil can cause our customers to remain sensitive to the pricing of our products and services. In the U.S., we monitor patient visits and clinic revenue data provided by a subset of our CAG customers. Although this data is a limited sample and susceptible to short-term impacts such as weather, which may affect the number of patient visits in a given period, we believe that this data provides a fair and meaningful long-term representation of the trend in patient visit activity in the U.S., providing us insight regarding demand for our products and services.

Economic conditions can also affect the purchasing decisions of our Water and LPD business customers. Water testing volumes may be susceptible to declines in discretionary testing for existing home and commercial sales and in mandated testing as a result of decreases in home and commercial construction. Testing volumes may also be impacted by severe weather conditions such as drought. In addition, fiscal difficulties can also reduce government funding for water and livestock testing programs.

We believe that the diversity of our products and services and the geographic diversity of our markets partially mitigate the potential effects of the economic environment and negative consumer sentiment on our revenue growth rates.

Effects of Patent Expiration . Although the Company has several patents and licenses of patents and technologies from third parties that expired during 2015 and are expected to expire during 2016 and 2017, the expiration of these patents or licenses, individually or in the aggregate, is not expected to have a material effect on the Company’s financial position or future operations due to a range of factors including our brand strength and reputation in the marketplace; the breadth, quality and integration of our product offerings; our existing customer relationships and our customer support; our sales force; the applicable regulatory approval status for certain products; our continued investments in innovative product improvements that often result in new technologies and/or additional patents; and our significant know-how, scale and investments related to manufacturing processes of associated product offerings. See “Part I. Item 1. Business - Patents and Licenses” of our 2015 Annual Report for more information.

Critical Accounting Policies and Estimates

The discussion and analysis of our financial condition and results of operations is based upon our condensed consolidated financial statements, which have been prepared in accordance with U.S. GAAP. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. We evaluate our estimates on an ongoing basis. We base our estimates on historical experience and on various assumptions 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 that are not readily apparent from other sources. Actual results may differ from these estimates . T he critical accounting policies and the significant judgments and estimates used in the preparation of our condensed consolidated financial statements for the three and six months ended June 30 , 2016 are consistent with those discussed in our 2015 Annual Report in the section under the heading “Part II, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting Policies and Estimates.”

Results of Operations

The following revenue analysis and discussion focuses on organic revenue growth, and references in this analysis and discussion to “revenue,” “revenues” or “revenue growth” are references to “organic revenue growth.” Organic revenue growth is a non-GAAP financial measure and represents the percentage change in revenue during the three and six mon ths ended June 30 , 2016, as compared to the same period s for the prior year, net of the effect of changes in foreign currency exchange rates, acquisitions and divestitures. Organic revenue growth should be considered in addition to, and not as a replacement for , or as a superior measure to, revenues reported in accordance with U.S. GAAP, and may not be comparable to similarly titled measures reported by other companies. Management believes that reporting organic revenue growth provides useful information to investors by facilitating easier comparisons of our revenue performance with prior and future periods and to the performance of our peers. We exclude the effect of changes in foreign currency exchange rates because changes in foreign currency exchange rates are not under management’s control, are subject to volatility and can obscure underlying business trends. We exclude the effect of acquisitions and divestitures because the nature, size and number of these transactions can vary dramatically from period to period, require or generate cash as an inherent consequence of the transaction, and therefore can also obscure underlying business and operating trends.

Organic revenue growth and the percentage changes in revenue from foreign currenc y exchange rates and acquisitions are non- GAAP financial measures. See the subsection above titled “ Effects of Certain Factors and Trends on Results of Operations – Currency Impact ” for a description of the calculation of the percentage change in revenue resulting from changes in foreign currency exchange rates. The percentage change in revenue resulting from acquisitions represents incremental revenues attributable to acquisitions that have occurred since the beginning of the prior year period.

The increase in both U.S. and international orga nic revenues was driven by CAG D iagnostics recurring revenue primarily resulting from higher sales volumes. The increase in organic international revenues was driven primarily by growth in Europe and the Asia-Pacific markets and, to a lesser extent, Canada and Latin America .

The increase in CAG D iagnostics recurring revenue was due primarily to higher sales from our reference laboratory diagnostic services and of our IDEXX VetLab consumables resulting from increased volumes and, to a lesser extent, higher realized prices.

IDEXX VetLab consumables revenue growth was due primarily to higher sales volumes in the U.S., Europe and the Asia-Pacific region for our Catalyst consumables and, to a lesser extent, ProCyte Dx ® consumables, resulting from growth in testing by existing customers, an expanded menu of available tests and the net acquisition of new customers. These favorable impacts were partly offset by lower consumables volumes from our VetTest ® chemistry instrument due to customer upgrades from our previous generation VetTest to our Catalyst analyzers. IDEXX VetLab consumables revenue also benefited from higher average unit sales prices.

IDEXX VetLab service and accessories revenue growth was primarily a result of the increase in our active installed base of instruments.

The increase in rapid assay revenue resulted from higher SNAP 4Dx ® and si ngle analyte SNAP ® sales volumes , with incremental SNAP 4Dx volumes primarily attributable to the timing of our marketing program s . We also benefitted from higher average unit sales prices on our 4Dx product line.

CAG D iagnostic s capital instrument placements, including our Sedivue ™ Dx urin alysis instrument , which we began shipping in April 2016, dr i ve highly profitable recurring diagnostics revenue. Our Catalyst One ® analyzer continued to drive strong worldwide chemistry placements, while our hematology placements continue d to be driven by Procyte Dx in Europe and the U. S. The increase in CAG D iagnostics capital instruments revenue resulted from our newly launched SediVue Dx analyzer , which contributed 28% to reported and organic growth, and an increase in ProCyte Dx revenues , partly offset by lower Catalyst revenues resulting from a shift in placements from our Catalyst Dx ® analyzer to our lower priced Catalyst One analyzer.

The increase in veterinary software, services and diagnostic imaging systems revenue was due primarily to increasing veterinary subscription service revenue, higher support revenue resulting from an increase in our installed base and higher sales of diagnostic imaging systems. Higher revenues from diagnostic imaging systems resulted from fewer relative deferred revenue placements under up-front customer loyalty programs and the recognition of previously deferred revenues. These favorable factors were partially offset by fewer licensed-based Cornerstone ® placements as we evolve to a subscription-based model for new practice management customer acquisitions, as well as lower average unit sale prices on diagnostic imaging system placements.

Water. The increase in Water revenue was attributable to all regions in which we operate, most notably from strong performance in North America, Europe and the Asia-Pacific region. Higher revenues resulted primarily from increased sales volumes and price increases of our Colilert ® test products and related accessories used in coliform and E. coli testing. We also benefitted from several large project orders during the quarter and to a lesser extent, from higher sales volumes of our products designed to detect cryptosporidium , related to an outbreak in the United Kingdom which we expect to subside in the second half of 2016 and placements of our Quanti-Tray Sealer PLUS instrument, which we launched in June 2015.

Livestock, Poultry and Dairy. The increase in LPD revenue resulted from strong performance in emerging markets, most notably resulting from higher sales volumes of our swine and poultry testing products in China and Southeast Asia and increased herd health screening services in Brazil . These favorable factors were partly offset by decreased sales volumes of bovine testing products within Western Europe in large part due to the success of certain disease eradication programs in that region.

Other. The increase in Other revenue was due primarily to royalty revenue associated with the commercialization of certain intellectual property related to our former pharmaceutical product line.

Gross Profit

Total Company. The following table presents gross profit (loss) and gross profit percentages by operating segment:


	For the Three			For the Three
Gross Profit (Loss)	Months Ended		Percent of	Months Ended		Percent of		Dollar	Percentage
(dollars in thousands)	June 30, 2016		Revenue	June 30, 2015		Revenue		Change	Change

Water		19,380	69.6%		18,013	71.9%		1,367	7.6%
LPD		19,178	58.4%		20,170	62.9%		(992)	(4.9%)

Total Company	$	260,543	55.8%	$	232,757	56.3%	$	27,786	11.9%

Gross profit increased due to higher sales, partly offset by an approximately 50 basis points decrease in the gross profit percentage. The decrease in gross profit percentage was due primarily to the unfavorable impact of currency during the three months ended June 30, 2016, as compared to the same period of the prior year, resulting from lower relative hedging gains. Excluding currency impacts of approximately 120 basis points, gross margins increased moderately, supported by favorability in our CAG business.

Companion Animal Group. Gross profit for CAG increased due to higher sales and a slight increase in the gross profit percentage, despite approximately 90 basis points of unfavorable currency impacts during the three months ended June 30, 2016, as compared to the same pe riod of the prior year, resulting primarily from lower relative hedging gains. The gr oss profit percentage increase was supported by price increases on our CAG D iagnostics recurring revenue portfolio and profitab ility improvements across o ur worldwide network of reference laboratories and from higher relative revenues from expanded subscription service offerings. These favorable impacts offset an unfavorable product mix resulting from higher relative instrument revenues and lower relative revenue from our rapid assay test kits , and increased product costs in our IDEXX VetLab and rapid assay businesses.

Water. Gross profit for Water increased due to higher sales, partly offset by a decrease in the gross profit percentage from 72% to 70% . The decrease in the gross profit percentage was due to the unfavorable impact of currency during the three months ended June 30, 2016, as compared to the same period of the prior year, resulting from lower relative hedging gains and changes in foreign currency exchange rates. Excluding currency impacts of approximately 220 basis points, the gross profit percentage increased slightly due to price increases on our Colilert testing products and related accessories.

Other. Gross profit for Othe r increased due to higher sales and an increase in the gross profit percentage from 36% to 40%. The in crease in the gross profit percentage resulted primarily from higher relative royalty revenue associated with the commercialization of certain intellectual property related to our former pharmaceutical product lin e, for which there is no associated cost of revenue, partly offset by higher overall OPTI Medical product costs.

Unallocated Amounts. Gross profit for Unallocated Amounts decreased due primarily to higher personnel-related costs. We estimate certain personnel-related costs and allocate the budgeted expenses to the operating segments. This allocation differs from the actual expense and consequently yields a difference that is reported under the caption “Unallocated Amounts.” The increase in personnel-related costs was due primarily to higher self-insured healthcare costs and higher than budgeted employee incentives reported within Unallocated Amounts during the three months ended June 30 , 2016 , as compared to the same period of the prior year.

	For the Three			For the Three
Operating Expenses	Months Ended		Percent of	Months Ended		Percent of		Dollar	Percentage
(dollars in thousands)	June 30, 2016		Revenue	June 30, 2015		Revenue		Change	Change

Total operating expenses	$	128,984	32.2%	$	124,671	35.5%	$	4,313	3.5%

The increase in sales and marketi ng expense, which reflects delays in timing for certain investments, was due primarily to higher commissions resulting from improved sales performance, partly off set by the favorable impact of changes in foreign currency exchange rates. The increase in general and administrative expense resulted primarily from information technology investments, including ongoing depreciation and maintenance associated with prior year projects, and higher personnel-related costs. Research and development expense for the three months ended June 30, 2016 was generally consistent with the same period of the prior year.

Water. The following table presents Water operating expenses by functional area:

Total operating expenses	$	6,637	23.8%	$	6,062	24.2%	$	575	9.5%

The increase in sales and marketing expense was due primarily to higher personnel - related costs and increased market research spend. The increase in general and administrative expense was due primarily to higher personnel - related costs. Research and development expense for the three months ended June 30, 2016 was generally consistent with the same period of the prior year.

Livestock, Poultry and Dairy. The following table presents LPD operating expenses by functional area:

Total operating expenses	$	14,109	42.9%	$	13,591	42.4%	$	518	3.8%

The decrease in sales and marketing expense was due primarily to the favorable impact of changes in foreign currency exchange rates. The increase in general and administrative expense resulted from higher personnel - related costs , including investments in emerging markets , partly off set by the favorable impact of changes in foreign currency exchange rates. The increase in research and development expense resulted from higher materials and external product development costs.

Other. Operating expenses for Other, which totaled $3.2 million for the three months ended June 30, 2016, increased $0.6 million , as compared to the same period of the prior year , due primarily to an intangible impairment within our OPTI Medical business, partly offset by lower amortization expense on the aforementioned intangible assets and a reduction in personnel- related costs.

During the first quarter of 2016, management reviewed our OPTI Medical product offering, which resulted in a discontinuance of our product development activities in the human point-of-care medical diagnostics market and a decision to focus our commercial efforts to support our latest generation OPTI CCA-TS2 Blood Gas and Electrolyte Analyzer . During the second quarter of 2016, management identified unfavorable trends in our OPTI Medical business resulting from this change in strategy. We revised our forecasts downward, causing us to assess the realizability of the related tangible and intangible assets and determined the expected future cash flows were less than the carrying value of the OPTI Medical asset group. Given this, a non-cash intangible asset impairment charge of $1.1 million was recorded within our condensed consolidated statement of operations for the three months ended June 30, 2016. As of June 30, 2016, the intangibles associated with our human point-of-care medical diagnostics market were fully written off. Management has reviewed the tangible assets associated with this line of business and does not anticipate further impairments at this time.

Unallocated Amounts. Operating expenses that are not allocated to our operating segments increased $5.9 million to $3.4 million for the three months ended June 30, 2016, due primarily to higher personnel-related costs, certain foreign exchange losses on monetary assets due to a strengthening of the U.S. dollar relative to the euro during the second quarter of 2016 and the absence of certain state tax incentives realized during the three months ended June 30, 2015.

We estimate certain personnel-related costs and allocate these budgeted expenses to the operating segments. This allocation differs from actual expense and consequently yields a difference that is reported under the caption “Unallocated Amounts.” During the three months ended June 30 , 2015, operating expenses reported in Una llocated Amounts benefitted favorabl y due to cost control initiatives enacted subsequent to the development of our 2015 budget. Additionally, higher personnel- related costs during the three months ended Ju ne 30, 2016 were the result of increased employee incentives and higher self-insured healthcare costs.

Interest Income and Interest Expense

Interest income was $0.9 million and $0.6 million for the three months ended June 30, 2016 and 2015, respectively. The increase in interest income was due primarily to a larger relative portfolio of marketable securities during the three months ended June 30, 2016 , as compared to the same period of the prior year.

Interest expense was $8.2 million for the three months ended June 30, 2016 , as compared to $7.3 million for the same period of the prior year. The increase in int erest expense resulted from higher average relative borrowings and interest rates on our unsecured revolving credit facility (“Credit Facility”). Additionally, incremental interest was incurred in 2016 as result of approximately $250 million in senior notes that we issued and sold through private placements during the first half of 2015, for which fixed interest rates range from 1.785% to 3.72 % . See Note 11 to the consolidated financial statements in our 2015 Annual Report for additional information regarding our senior notes and Credit Facility.

Provision for Income Taxes

Our effective income tax rate was 30.6% and 30.2% for the t hree months ended June 30, 2016 and 2015 , respectively . The increase in our effective rate for the three months ended June 30, 2016, as compared to the same period of the prior year, was primarily related to an earnings mix, with relatively higher earnings subject to domestic tax rates as opposed to lower international tax rates, including the impact of foreign currency exchange rates. This increase in effective tax rates, period over period, was mostly offset by the U.S. R&D tax credit. There was no available R&D tax credit during the period ending June 30, 2015, because the credit had not yet been extended. In December 2015, the R&D tax credit was permanently extended with retroactive application to January 1, 2015. As a result, we fully recognized the related 2015 tax benefit entirely in the fourth quarter of 2015.

IDEXX VetLab consumables revenue growth was due primarily to higher sales volumes in the U.S., Europe and the Asia-Pacific region for our Catalyst consumables and, to a lesser extent, ProCyte Dx consumables, resulting from growth in testing by existing customers, an expanded menu of available tests and the net acquisition of new customers. These favorable impacts were partly offset by lower consumables volumes from our VetTest chemistry instrument due to customer upgrades from our previous generation VetTest to our Catalyst analyzers. IDEXX VetLab consumables revenue also benefited from higher average unit sales prices.

IDEXX VetLab service and accessories revenue growth was primarily a result of the increase in our active installed base of instruments.

The increase in rapid assay revenue resulted from higher SNAP 4Dx and si ngle analyte SNAP sales volumes . These favorable factors were partly offset by the unfavorable impact of lower average unit sales prices in the U.S. for certain earlier generation r apid assay products.

The increase in reference laboratory diagnostic and consulting services revenue was due primarily to the impact of higher testing volumes throughout our worldwide network of laboratories, most prominently in the U.S ., resulting from increased testing from existing customers, the net acquisition of new customers, supported by our differentiated diagnostic technologies, such as IDEXX SDMA . Additionally, the increase in revenue was the result of higher average unit sales prices due to price increases. Testing volumes benefitted slightly from favorable weather trends experienced during the first quarter of 2016 , as compared to the same period of the prior year , and an extra business day in the first half of 2016 due to a leap year.

CAG D iagnostic s capital instrument placements , including our Sedivue Dx urinalysis instrument which we began shipping in April 2016, dr i ve highly profitable recurring diagnostics revenue. Our Catalyst One analyzer continues to drive strong worldwide chemistry placements, while our hematology placements continue to be driven by Procyte Dx in Europe and the U.S. The increase in CAG D iagnostics capital instruments revenue resulted from our newly launched SediV ue Dx analyzer, which contributed 15% to reported and organic growth, and higher ProCyte Dx revenues , partly offset by lower Catalyst revenues resulting from a shift in placements from our Catalyst Dx analyzer to our lower priced Catalyst One analyzer.

The increase in v eterinary s oftware , services and diagnostic i maging s ystems revenue was due primarily to increasing diagnostic imaging systems revenue, higher veterinary subscription service revenue, higher support revenue resulting from an increa se in our active installed base of diagnostic imaging and practice management systems and higher reven ues resulting from an increase in our Pet Health Network Pro ® subscriber base. Higher revenues from diagnostic imaging systems resulted from fewer relative deferred revenue placements under up-front customer loyalty programs and the recognition of previously deferred revenues. These favorable factors were partially offset by fewer licensed-based Cornerstone placements as we evolve to a subscription-based model for new practice management customer acquisitions, as well as lower average unit sale prices on diagnostic imaging system placements.

Water. The increase in Water revenue was attributable to all regions in which we operate, most notably from strong performance in North America, Europe and the Asia-Pacific region. Higher revenues resulted primarily from increased sales volumes and price increases of our Colilert test products and related accessories used in coliform and E. coli testing, several large project orders during the first half of 2016 and to a lesser extent, from higher sales volumes of our products designed to detect cryptosporidium , related to an outbreak in the United Kingdom which we expect to subside in the second half of 2016 and placements of our Quanti-Tray Sealer PLUS instrument, which we launched in June 2015. Testing volumes benefitted slightly from favorable weather trends experienced during the first quarter of 2016 as compared to the same period of the prior year.

Livestock, Poultry and Dairy. The increase in LPD revenue resulted from strong performance in emerging markets, most notably resulting from higher sales volumes of swine, poultry and bovine pregnancy testing products in China and Southeast Asia and increased sales volumes of our dairy testing products in Brazil. We also benefitted from increased herd health screening services in Brazil and the Asia-Pacific region. These favorable factors were partly offset by decreased sales volumes of bovine testing products within Western Europe in large part due to the success of certain disease eradication programs in the region.

Other. The increase in Other revenue was due primarily to royalty revenue associated with the commercialization of certain intellectual property related to our former pharmaceutical product line.

Gross profit increased due to higher sales, partly offset by a decrease in the gross profit percentage from 56% to 55 % . The gross profit percentage decreased approximately 120 basis points from an unfavorable impact of currency during the six months ended June 30, 2016, as compared to the same period of the prior year, resulting primarily from lower relative hedging gains. Excluding these currency impacts, the gross profit percentage increased slightly, supported by higher average unit sales prices for our reference laboratory diagnostic services and IDEXX VetLab consumables and profitability improvements from higher relative revenue of our expanded subscription service offerings and across our worldwide netwo rk of reference laboratories. These favorable impacts were almost entirely offset by an increase in product costs in our VetLab, OPTI Medical and LPD lines of business and an unfavorable product mix resulting from higher relative CAG Diagnostics capital revenues and lower relative revenue from rapid assay test kits.

Companion Animal Group. Gross profit for CAG increased due to higher sales, partly offset by a decrease in the gross profit percentage from 55% to 54 %. The decrease in gross profit percentage was due primarily to the unfavorable impact of currency during the six months ended June 30, 2016, as compared to the same period of the prior year, resulting from lower relative hedging gains. Excluding currency impacts of approximately 90 basis points, gross margins increased moderately, supported by price increases for our reference laboratory diagnostic services and IDEXX VetLab consumables and profitability improvements from higher relative revenue of our expanded subscription service offerings, and within our worldwide netwo rk of reference laboratories . These benefits offset an unfavorable product mix resulting primarily from higher relative instrument revenue and lower relative revenue from our rapid assay test kits and an increase in IDEXX VetLab product costs.

Water. Gross profit for Water increased due to higher sales, partly offset by a decrease in the gross profit percentage from 71% to 69%. The decrease in the gross profit percentage was due to the unfavorable impact of currency during the six months ended June 30, 2016, as compared to the same period of the prior year, resulting from lower relative hedging gains and changes in foreign currency exchange rates. Excluding currency impacts of approximately 220 basis points, the gross profit percentage increased slightly due to price increases on our Colilert testing products and related accessories.

Livestock, Poultry and Dairy. Gross profit for LPD decreased due to a reduction in the gross profit percentage from 63% to 58%, partly offset by higher sales. The decrease in the gross profit percentage resulted primarily from approximately 430 basis points of unfavorable impact from changes in foreign currency exchange rates and higher overall product costs. The negative effect of currency resulted from hedging losses realized during the six months ending June 30, 2016, as compared to hedging gains realized during the same period of the prior year. These unfavorable factors were partly offset by the expiration of royalties on certain of our swine testing products and a favorable product mix resulting from higher relative herd health screening revenues.

Other. Gross profit for Other increased due to higher sales and an increase in the gross profit percentage from 43% to 47%. The in crease in the gross profit percentage resulted primarily from higher relative royalty revenue associated with the commercialization of certain intellectual property related to our former pharmaceutical product line , partly offset by an increase in overall OPTI Medical product costs .

Unallocated Amounts. Gross profit for Unallocated Amounts decreased due primarily to higher personnel-related costs. We estimate certain personnel-related costs and allocate the budgeted expenses to the operating segments. This allocation differs from the actual expense and consequently yields a difference that is reported under the caption “Unallocated Amounts.” The increase in personnel-related costs was due primarily to higher self-insured healthcare costs and higher than budgeted employee incentives reported within Unal located Amounts during the six months ended June 30 , 2016 , as compared to the same period of the prior year.

Companion Animal Group. The following table presents CAG operating expenses by functional area:


	For the Six			For the Six
Operating Expenses	Months Ended		Percent of	Months Ended		Percent of		Dollar	Percentage
(dollars in thousands)	June 30, 2016		Revenue	June 30, 2015		Revenue		Change	Change

Total operating expenses	$	258,398	34.1%	$	248,087	36.7%	$	10,311	4.2%

The increase in sales and marketing expense was due primarily to increased personnel-related costs, including investments in our global sales infrastructure and higher commissions resulting from improved sales performance, partly off set by the favorable impact of changes in foreign currency exchange rates. The increase in general and administrative expense resulted primarily from information technology investments, including ongoing depreciation and maintenance associated with prior year projects, and higher personnel-related costs, partly offset by the favorable impact of changes in foreign currency exchange rates. Research and development expense for the six months ended June 30, 2016 was generally consistent with the same period of the prior year.

Total operating expenses	$	13,064	25.4%	$	11,849	25.3%	$	1,215	10.3%

The increase in sales and marketing expense was due primarily to higher personnel-related costs and an increase in market research spend. The increase in general and administrative expense was du e primarily to higher personnel- related costs , partly offset by the favorable impact of changes in foreign currency exchange rates . Research and development expense for the six months ended June 30, 2016 was generally consistent with the same period of the prior year, as higher personnel-related costs were offset by lower materials costs.

Livestock, Poultry and Dairy. The following table presents LPD operating expenses by functional area:


	For the Six			For the Six

Total operating expenses	$	27,516	43.2%	$	26,643	42.1%	$	873	3.3%

Sales and marketing expense for the six months ended June 30, 2016 was generall y consistent with the same period of the prior year as commercial infrastructure investments within emerging markets were offset by the favorable impact of changes in foreign currency exchange rates. The increase in general and administrative expense resulted from higher personnel- related costs, partly off set by the favorable impact of changes in foreign currency exchange rates. The increase in research and development expense resulted from higher external product development and material costs.

Other. Operating expenses for Other, which totaled $7.0 million for the six months ended June 30, 2016, increased $1.6 million , as compared to the same period of the prior year , due primarily to intangible impairments within our OPTI Medical business, partly offset by lower amortization expense on the aforementioned intangible assets and a reduction in personnel- related costs.

Unallocated Amounts. Operating expenses that are not allocated to our o perating segments increased $9.0 million to $4.2 million for the six months ended June 30, 2016, due primarily to higher personnel-related costs and, to a lesser extent, certain foreign exchange losses on monetary assets due to a strengthening of the U.S. dollar relative to certain foreign currencies in which we transact during the first half of 2016 and the absence of certain state tax ince ntives realized during the six months ended June 30, 2015. We estimate certain personnel-related costs and allocate these budgeted expenses to the operating segments. This allocation differs from actual expense and consequently yields a difference that is reported under the caption “Unallocated Amounts.” During the six months ended June 30 , 2015, operating expenses reported in Unal located Amounts benefitted favorabl y due to cost control initiatives enacted subsequent to the development of our 2015 budget. Additionally, higher personnel - related costs during the six months ended J une 30, 2016 were the result of increased employee incentives and higher self-insured healthcare costs.

Interest Income and Interest Expense

Interest income was $1.7 million and $1.0 million for the six months ended June 30, 2016 and 2015, respectively. The increase in interest income was due primarily to a larger relative portfolio of marketable securities during the six months ended June 30, 2016 , as compared to the same period of the prior year.

Interest expense was $16.5 million for the six months ended J une 30, 2016, as compared to $13.6 million for the same period of the prior year. The increase in int erest expense resulted from higher relative interest incurred in 2016 as result of approximately $250 million in senior notes that we issued and sold through private placements during the first half of 2015, for which fixed interest rates range from 1.785% to 3.72 % . Additionally, the increase in interest expense was due to higher relative interest rates and average borrowings on our Credit Facility. See Note 11 to the consolidated financial statements in our 2015 Annual Report for additional information regarding our senior notes and Credit Facility.

Provision for Income Taxes

Our effective income tax rate was 30.6% and 30.3% for the six months ended June 30, 2016 and 2015, respectively. The increase in our effective rate for the six months ended June 30, 2016 , as compared to the same period of the prior year , was primarily related to an earnings mix, with relatively higher earnings subject to domestic tax rates as opposed to lower international tax rates, including the impact of foreign currency exchange rates. This increase in effective tax rates, period over period, was mostly offset by the U.S. R&D tax credit. There was no available R&D tax credit during the period ending June 30, 2015 because the credit had not yet been extended. In December 2015, the R&D tax credit was permanently extended with retroactive application to January 1, 2015. As a result, we fully recognized the related 2015 tax benefit entirely in the fourth quarter of 2015.

Recent Accounting Pronouncements

We are evaluating the impact that several recent accounting amendments related to share-based payment transactions, leases, and revenue recognition will have on our consolidated financial statements. Other recently issued accounting pronouncements did not have and are not expected to have a significant effect on our financial condition and results of operations.

Liquidity and Capital Resources

Liquidity

We fund the capital needs of our business through cash on hand, funds generated from operations, proceeds from long-term senior note financings and amounts available under our $850 million Credit Facility. At June 30, 2016 and December 31, 2015, we had $370.2 million and $342.6 million, respectively, of cash, cash equivalents and marketable securities. Working capital, including our Credit Facility, totaled negative $1.7 million and negative $35.1 million, respectively, at June 30, 2016 and December 31, 2015. Additionally, at June 30, 2016, we had remaining borrowing availability of $2 9 1 million under our $850 million Credit Facility. We believe that, if necessary, we could obtain additional borrowings at similar rates to our existing borrowings to fund our growth objectives. We further believe that current cash and cash equivalents, our portfolio of short-duration marketable securities, funds generated from operations and committed borrowing availability will be sufficient to fund our operations, capital purchase requirements, and anticipated growth needs for the next twelve months. We believe that these resources, coupled with our ability, as needed, to obtain additional financing on favorable terms will also be sufficient for the foreseeable future to fund our business as currently conducted.

We consider the majority of the operating earnings of certain of our non-U.S. subsidiaries to be indefinitely invested outside the U.S. No provision has been made for the payment of U.S. federal and state or international taxes that may result from future remittances of these undistributed earnings of our non-U.S. subsidiaries. Changes to this position could have adverse tax consequences. A determination of the related tax liability that would be paid on these undistributed earnings if repatriated is not practicable for several reasons, including the complexity of laws and regulations in the various jurisdictions where we operate, the varying tax treatment of potential repatriation scenarios and the timing of any future repatriation. We manage our worldwide cash requirements considering available funds among all of our subsidiaries. Our foreign cash and marketable securities are generally available without restrictions to fund ordina ry business operations outside the U.S.

Of our total cash, cash equivalents and marketable securities at June 30, 2016, approximately $365.4 million was held by our foreign subsidiaries and was subject to material repatriation tax effects. We held marketable securities with original maturities of three years or less that had an average AA- credit rating as of June 30, 2016. Of the $229.1 million in marketable securities held as of June 30, 2016, approximately 63% of the fair value of our marketable securities consisted of corporate bonds, 12% consisted of asset backed securities, with the remainder consisting of agency bonds, U.S. and Canadian government bonds, municipal bonds, commercial paper and certificates of deposit. Of the $141.1 million of cash and cash equivalents held as of June 30, 2016, 90% was held as bank deposits, with the remainder invested in money market funds invested in highly liquid investment-grade and U.S. government and agency fixed-income securities, commercial paper and agency bonds with original maturities of less than ninety days. As of June 30, 2016, approximately 70 % of cash, cash equivalents and marketable securities held by our foreign subsidiaries was held in U.S. dollars.

Should we require more capital in the U.S. than is generated by our operations domestically, for example to fund significant discretionary activities, we could elect to repatriate future earnings from foreign jurisdictions or raise capital in the U.S. through debt or equity issuances. These alternatives could result in higher effective tax rates or increased interest expense and other dilution of our earnings. We have borrowed funds domestically and believe we will continue to have the ability to borrow funds domestically at reasonable interest rates.

The following table presents additional key information concerning working capital:

Operating Activities. Cash provided by operating activities was $13 4 . 1 million for the six months ended June 30, 2016, as compared to $65.5 million for the same period of the prior year. The total of net income and net non-cash charges, excluding the impact of reclassifying the tax benefit from share-based compensation arrangements to a financing activity, was $166.9 million for the six months ended June 30, 2016, as compared to $145.9 million for the same period in 2015, resulting in increment al operating cash flows of $21.0 million driven primarily by higher net income and increased depreciation and amortization expense during the six months ended June 30, 2016. The total of changes in operating assets and liabilities and the tax benefit from share-based compensation arra ngements decreased cash by $32.8 million and $80.4 million for the six months ended June 30, 2016 and 2015, respectively, resulting in an incre mental increase in cash of $47.6 million.

The following table presents cash flows from changes in operating assets and liabilities and the tax benefit from share-based compensation arrangements:


	For the Six Months Ended June 30,

The decrease in cash used by accounts receivable during the six months ended June 30, 2016 resulted from the absence of one-time impacts related to our change in U.S. commercial strategy beginning in the fourth quarter of 2014. Our transition to an all-direct strategy in the U.S., including the establishment of accounts receivable directly with our U.S. end-users that previously purchased from our U.S. distribution partners, resulted in a significant use of cash during the first half of 2015. Cash provided by inventory during the six months ended June 30, 2016, as compared to cash used during the same period in the prior year, was the result of operational initiativ es to optimize inventory levels following a period of inventory growth to support new products and increasing demand. Cash used by other assets and liabilities during the six months ended June 30, 2016 was the result of higher taxable income as compared to the same period in the prior year. Income tax payments were lower duri ng the first half of 2015 resulting from one-time impacts of implementing our U.S. all-direct strategy and the benefit from the Tax Increase Prevention Act enactment late in the fourth quarter of 2014, resulting in cash provided by other assets and liabilities during the six months ended June 30, 2015.

We have historically experienced proportionally lower net cash flows from operating activities during the first quarter and proportionally higher cash flows from operating activities for the remainder of the year and for the annual period driven primarily by payments related to annual employee incentive programs in the first quarter following the year for which the bonuses were earned and the seasonality of vector-borne disease testing, which has historically resulted in significant increases in accounts receivable balances during the first quarter of the year.

Investing Activities. Cash used by investing activities was $5 3.6 million for the six months ended June 30, 2016 , as compared to $227.6 million for the same period of the prior year. The decrease in cash used by investing activities was due primarily to lower relative net purchases of marketable securities during the six months ended June 30, 2016 as compared to the same period of the prior year.

Our total capital expenditure plan for 2016 is e stimated to be approximately $90 million, which includes capital investments in manufacturing and reference laboratory equipment, investments in internal use software and information technology infrastructure and the renovation and expansion of our facilities and reference laboratories.

Financing Activities. Cash used b y financing activities was $72.0 million for the six months ended June 30 , 2016 , as compared to cash provided of $3.3 million for the same p eriod in 2015. C ash used for financing activities during the six months ended June 30, 2016 was due to the absence of a long-term de bt issuance in the first half of 2016, as compared to the aggregate issuance of approximately $250 million of senior notes during the same period of the prior year, partly offset by a decrease in cash used to repurc hase our common stock and lower relative net repayments under the Credit Facility during the six months ended June 30, 2016, as compared to the same period of the prior year.

Cash used to repurchase shares of our common stock decreased $143. 6 million during the six months ended June 30, 2016, as compared to the same period of the prior year. Share repurchases have moderated relative to the same period of the prior year as we have achieved a debt leverage ratio consistent with our long-term target range. From the inception of our share repurchase program in August 1999 to June 3 0 , 2016, we have repurchased 59.2 million shares. During the six months ended June 30, 2016, we purchased 1.0 million shares for a cash outflow of $ 76.5 million, as compared to purchases of 3.1 million shares for a cash outflow of $220.1 million during the same period of the prior year. We believe that the repurchase of our common stock is a favorable means of returning value to our shareholders and we also repurchase our stock to offset the dilutive effect of our share-based compensation programs. Repurchases of our common stock may vary depending upon the level of other investing activities and the share price. See Note 9 to the condensed consolidated financial statements included in this Quarterly Report on Form 10-Q for additional information about our share repurchases.

Net borrowing and repayment activity under the Credit Facility resulted in incremental cash provided of $36.0 million during the six months ended June 30, 2016, as compared to the same period of the prior year. At June 30, 2016, we had $558.0 million outstanding under the Credit Facility. The general availability of funds under the Credit Facility was further reduced by $1.0 million for a letter of credit that was issued in connection with claims under our workers’ compensation policy. The Credit Facility contains affirmative, negative and financial covenants customary for financings of this type. The negative covenants include restrictions on liens, indebtedness of subsidiaries of the Company, fundamental changes, investments, transactions with affiliates, certain restrictive agreements and violations of laws and regulations. The obligations under the Credit Facility may be accelerated upon the occurrence of an event of default under the Credit Facility, which includes customary events of default including payment defaults, defaults in the performance of the affirmative, negative and financial covenants, the inaccuracy of representations or warranties, bankruptcy and insolvency related defaults, defaults relating to judgments, certain events related to employee pension benefit plans under the Employee Retirement Income Security Act of 1974, the failure to pay specified indebtedness, cross-acceleration to specified indebtedness and a change of control default.

Since December 2013, we have issued and sold through private placements senior notes having an aggregate principal amount of approximately $600 million pursuant to certain note purchase agreements (collectively, the “Senior Note Agreements”). The Senior Note Agreements contain affirmative, negative and financial covenants customary for agreements of this type. The negative covenants include restrictions on liens, indebtedness of our subsidiaries, priority indebtedness, fundamental changes, investments, transactions with affiliates, certain restrictive agreements and violations of laws and regulations. See Note 11 to the consolidated financial statements in our 2015 Annual Report for additional information regarding our senior notes.

Should we elect to prepay the senior notes, such aggregate prepayment will include the applicable make-whole amount(s), as defined within the applicable Senior Note Agreements. Additionally, in the event of a change in control of the Company or upon the disposition of certain assets of the Company the proceeds of which are not reinvested (as defined in the Senior Note Agreements), we may be required to prepay all or a portion of the Senior Notes. The obligations under the Senior Notes may be accelerated upon the occurrence of an event of default under the applicable Senior Note Agreement, each of which includes customary events of default including payment defaults, defaults in the performance of the affirmative, negative and financial covenants, the inaccuracy of representations or warranties, bankruptcy and insolvency related defaults, defaults relating to judgments, certain events related to employee pension benefit plans under the Employee Retirement Income Security Act of 1974, the failure to pay specified indebtedness and cross-acceleration to specified indebtedness.

The sole financial covenant of our Credit Facility and Senior Note Agreements is a consolidated leverage ratio test that requires our ratio of debt to earnings before interest, taxes, depreciation and amortization and certain other non-cash charges (“Adjusted EBITDA”) not to exceed 3.5-to-1. At June 30, 2016, we were in compliance with the covenants of the Credit Facility and Senior Note Agreements. The following details our consolidated leverage ratio calculation as of June 30, 2016:


	June 30,
Trailing 12 Months Adjusted EBITDA:		2016

Net income attributable to stockholders	$	201,793

M a n a g e m e n t b elie v es t h at reporting these non-GAAP financial measures provides supplemental analysis to help investors further evaluate our business performance and available borrowing capacity under our Credit Facility.

Other Commitments, Contingencies and Guarantees

Significant commitments, contingencies and guarantees at June 30, 2016 are consistent with those discussed in the section under the heading “Part II , Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources,” and in Note 14 to the consolidated financial statements in our 2015 Annual Report .

Item 3. Quantitative and Qualitative Disclosures About Market Risk

For quantitative and qualitative disclosures about market risk affecting IDEXX, see the section under the heading “Part II, Item 7A. Quantitative and Qualitative Disclosures About Ma rket Risk” of our 2015 Annual Report. As of the date of this Quarterly Report on Form 10-Q, there have been no material changes to the ma rket risks described in our 2015 Annual Report.

Item 4. Controls and Procedures

Disclosure Controls and Procedures

Our management is responsible for establishing and maintaining disclosure controls and procedures, as defined by the S EC in its Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934 as amended (the “Exchange Act”). The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of an issuer that are designed to ensure that information required to be disclosed by the issuer in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC ’ s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the ev aluation of our disclosure con trols and procedures at June 30, 2016 , our Chief Executive Officer and Chief Financial Officer have concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.

Changes in Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under th e Exchange Act) during the three and six months ended June 30, 2016 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II — OTHER INFORMATION

Item 1. Legal Proceedings

Due to the nature of our activities, we are at times subject to pending and threatened legal actions that arise out of the ordinary course of business. In the opinion of management, based in part upon advice of legal counsel, the disposition of any such currently pending matters is not expected to have a material effect on our results of operations, financial condition or cash flows. However, the results of legal actions cannot be predicted with certainty. Therefore, it is possible that our results of operations, financial condition or cash flows could be materially adversely affected in any particular period by the unfavorable resolution of one or more legal actions.

Item 1A. Risk Factors

In addition to the other information set forth in this Quarterly Report on Form 10-Q, you should carefully consider the factors discussed in “Part I, Item 1A. Risk Factors" in our 2015 Annual Report, which could materially affect our business, financial condition or future results. There have been no material changes from the risk factors previously disclosed in the 2015 Annual Report. The risks described in our 2015 Annual Report are not the only risks facing our Company. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition or future results.

(1)

On August 13, 1999, our Board of Directors approved and announced the repurchase of our common stock in the open market or in negotiated transactions pursuant to the Company’s share repurchase program. The authorization has been increased by the Board of Directors on numerous occasions; most recently the maximum level of shares that may be repurchased under the program was increased to 65 million shares on June 15, 2015. There is no specified expiration date for this repurchase program. There were no other repurchase programs outstanding during the three months ended June 30, 2016, and no repurchase programs expired during the period. Repurchases of 269,066 shares were made during the three months ended June 30, 2016 in transactions made pursuant to our repurchase program.

(2)

During the three months ended June 30, 2016, we received 2,303 shares of our common stock that were surrendered by employees in payment for the minimum required withholding taxes due on the vesting of restricted stock units and settlement of deferred stock units. In the above table, these shares are included in columns (a) and (b), but excluded from columns (c) and (d). These shares do not reduce the number of shares that may yet be purchased under the repurchase program.
