1. DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION

Description of Business. As used herein, “Acacia” and the “Company” refer to Acacia Research Corporation and/or its wholly and majority-owned and controlled operating subsidiaries. All intellectual property acquisition, development, licensing and enforcement activities are conducted solely by certain of Acacia’s wholly and majority-owned and controlled operating subsidiaries.

Acacia’s operating subsidiaries acquire, develop, license and otherwise enforce patented technologies. Acacia’s operating subsidiaries generate revenues and related cash flows from the granting of intellectual property rights for the use of, or pertaining to, patented technologies that such operating subsidiaries own or control. Acacia’s operating subsidiaries assist patent owners with the prosecution and development of their patent portfolios, the protection of their patented technologies from unauthorized use, the generation of revenue from users of their patented technologies and, if necessary, the enforcement against unauthorized users of their patented technologies. Currently, on a consolidated basis, Acacia’s operating subsidiaries own or control the rights to over 274 patent portfolios, which include U.S. patents and certain foreign counterparts, covering technologies used in a wide variety of industries.

In January 2012, a wholly owned operating subsidiary of Acacia acquired ADAPTIX, Inc. (“ADAPTIX”), a pioneer in the development of 4G technologies for wireless systems, for cash consideration of $160 million , as described at Note 7 to these consolidated financial statements.

Basis of Presentation. The accompanying consolidated financial statements include the accounts of Acacia and its wholly and majority-owned and controlled subsidiaries. Material intercompany transactions and balances have been eliminated in consolidation. Noncontrolling interests in Acacia’s majority-owned and controlled operating subsidiaries (“noncontrolling interests”) are separately presented as a component of stockholders’ equity in the consolidated statements of financial position for the applicable periods presented. Consolidated net income (loss) is adjusted to include the net (income) loss attributed to noncontrolling interests in the consolidated statements of operations. Refer to the accompanying consolidated financial statements for total noncontrolling interests, net income (loss) attributable to noncontrolling interests and contributions from and distributions to noncontrolling interests, for the applicable periods presented.

A wholly owned subsidiary of Acacia is the general partner of the Acacia Intellectual Property Fund, L.P. (the “Acacia IP Fund”), which was formed in August 2010. The Acacia IP Fund is included in the Company’s consolidated financial statements for the periods presented, as Acacia’s wholly owned subsidiary, as the majority owner and general partner, has the ability to control the operations and activities of the Acacia IP Fund.

The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, certain information and footnotes required by accounting principles generally accepted in the United States of America in annual financial statements have been omitted or condensed in accordance with quarterly reporting requirements of the Securities and Exchange Commission (“SEC”). These interim consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto for the year ended December 31, 2012 , as reported by Acacia in its Annual Report on Form 10-K. The year-end consolidated balance sheet data was derived from audited financial statements but does not include all disclosures required by accounting principles generally accepted in the United States of America.

The consolidated financial statements of Acacia include all adjustments of a normal recurring nature which, in the opinion of management, are necessary for a fair statement of Acacia’s consolidated financial position as of June 30, 2013 , and results of its operations and its cash flows for the interim periods presented. The consolidated results of operations for the three and six months ended June 30, 2013 are not necessarily indicative of the results to be expected for the entire fiscal year.

2 . SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Revenue Recognition. Revenue is recognized when (i) persuasive evidence of an arrangement exists, (ii) all obligations have been substantially performed pursuant to the terms of the arrangement, (iii) amounts are fixed or determinable, and (iv) the collectibility of amounts is reasonably assured.

In general, revenue arrangements provide for the payment of contractually determined fees in consideration for the grant of certain intellectual property rights for patented technologies owned or controlled by Acacia’s operating subsidiaries. These rights typically include some combination of the following: (i) the grant of a non-exclusive, retroactive and future license to manufacture and/or sell products covered by patented technologies owned or controlled by Acacia’s operating subsidiaries, (ii) a covenant-not-to-sue, (iii) the release of the licensee from certain claims, and (iv) the dismissal of any pending litigation. The intellectual property rights granted may be perpetual in nature, extending until the expiration of the related patents, or can be granted for a defined, relatively short period of time, with the licensee possessing the right to renew the agreement at the end of each contractual term for an additional minimum upfront payment. Pursuant to the terms of these agreements, Acacia’s operating subsidiaries have no further obligation with respect to the grant of the non-exclusive retroactive and future licenses, covenants-not-to-sue, releases, and other deliverables, including no express or implied obligation on Acacia’s operating subsidiaries’ part to maintain or upgrade the technology, or provide future support or services. Generally, the agreements provide for the grant of the licenses, covenants-not-to-sue, releases, and other significant deliverables upon execution of the agreement, or upon receipt of the minimum upfront payment for term agreement renewals. As such, the earnings process is complete and revenue is recognized upon the execution of the agreement, when collectibility is reasonably assured, or upon receipt of the minimum upfront fee for term agreement renewals, and when all other revenue recognition criteria have been met.

Cost of Revenues . Cost of revenues include the costs and expenses incurred in connection with Acacia’s patent licensing and enforcement activities, including inventor royalties paid to original patent owners, contingent legal fees paid to external patent counsel, other patent-related legal expenses paid to external patent counsel, licensing and enforcement related research, consulting and other expenses paid to third parties and the amortization of patent-related acquisition costs. These costs are included under the caption “Cost of revenues” in the accompanying consolidated statements of operations.

Inventor Royalties and Contingent Legal Expenses. Inventor royalties are expensed in the consolidated statements of operations in the period that the related revenues are recognized. In certain instances, pursuant to the terms of the underlying inventor agreements, costs paid by Acacia’s operating subsidiaries to acquire patents are recoverable from future net revenues. Patent acquisition costs that are recoverable from future net revenues are amortized over the estimated economic useful life of the related patents, or as the prepaid royalties are earned by the inventor, as appropriate, and the related expense is included in amortization expense in the consolidated statements of operations. Any unamortized patent acquisition costs recovered from net revenues are expensed in the period recovered, and included in amortization expense in the consolidated statements of operations.

Contingent legal fees are expensed in the consolidated statements of operations in the period that the related revenues are recognized. In instances where there are no recoveries from potential infringers, no contingent legal fees are paid; however, Acacia’s operating subsidiaries may be liable for certain out of pocket legal costs incurred pursuant to the underlying legal services agreement. Legal fees advanced by contingent law firms that are required to be paid in the event that no license recoveries are obtained are expensed as incurred and included in liabilities in the consolidated balance sheets.

Use of Estimates. The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates. Acacia believes that, of the significant accounting policies described herein, the accounting policies associated with revenue recognition, stock-based compensation expense, impairment of marketable securities and intangible assets, the determination of the economic useful life of amortizable intangible assets, income taxes and valuation allowances against net deferred tax assets and the application of the acquisition method of accounting for business combinations, require its most difficult, subjective or complex judgments.

Concentrations. Three licensees individually accounted for 41% , 20% and 12% of revenues recognized during the three months ended June 30, 2013 , and three licensees accounted for 50% , 15% and 11% of revenues recognized during the six months ended June 30, 2013 . One licensee individually accounted for 72% of revenues recognized during the three months ended June 30, 2012 and four licensees accounted for 36% , 24% , 13% and 12% of revenues recognized during the six months

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

ended June 30, 2012 . Three licensees individually represented approximately 56% , 20% and 17% of accounts receivable at June 30, 2013 . Three licensees individually represented approximately 34% , 30% , and 25% of accounts receivable at December 31, 2012. For the three and six months ended June 30, 2013 , 44% and 22% , respectively, of revenues were attributable to licensees domiciled in foreign jurisdictions. For the three and six months ended June 30, 2012 , 10% and 53% , respectively, of revenues were attributable to licensees domiciled in foreign jurisdictions.

Stock-Based Compensation. The compensation cost for all stock-based awards is measured at the grant date, based on the fair value of the award, and is recognized as an expense, on a straight-line basis, over the employee’s requisite service period (generally the vesting period of the equity award) which is generally two to four years . The fair value of restricted stock and restricted stock unit awards is determined by the product of the number of shares or units granted and the grant date market price of the underlying common stock. Stock-based compensation expense is recorded only for those awards expected to vest using an estimated forfeiture rate.

Fair Value Measurements. U.S. generally accepted accounting principles define fair value as the price that would be received for an asset or the exit price that would be paid to transfer a liability in the principal or most advantageous market in an orderly transaction between market participants on the measurement date, and also establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs, where available. The three-level hierarchy of valuation techniques established to measure fair value is defined as follows:



	●	Level 1 - Observable Inputs: Quoted prices in active markets for identical investments;
	●	Level 2 - Pricing Models with Significant Observable Inputs: Other significant observable inputs, including quoted prices for similar investments, interest rates, credit risk, etc.; and
	●	Level 3 - Unobservable Inputs: Significant unobservable inputs, including the entity’s own assumptions in determining the fair value of investments.

Whenever possible, the Company is required to use observable market inputs (Level 1 - quoted market prices) when measuring fair value.

Investments in Marketable Securities. Investments in securities with original maturities of greater than three months and less than one year and other investments representing amounts that are available for current operations are classified as short-term investments, unless there are indications that such investments may not be readily sold in the short term. The fair values of these investments approximate their carrying values. At June 30, 2013 and December 31, 2012, all of Acacia’s short term investments were classified as available-for-sale, which are reported at fair value on a recurring basis using significant observable inputs (Level 1), with related unrealized gains and losses in the value of such securities recorded as a separate component of comprehensive income (loss) in stockholders’ equity until realized. Realized and unrealized gains and losses are recorded based on the specific identification method. Interest on all securities is included in interest income.

Short-term marketable securities for the periods presented were comprised of the following (in thousands):



	June 30, 2013
Security Type	Cost		Gross Unrealized Gains		Gross Unrealized Losses			Fair Value
U.S. government fixed income securities ⁽¹⁾	$	171,881	$	31	$	(696	)	$	171,216

Impairment of Marketable Securities. Acacia evaluates its investments in marketable securities for potential impairment, employing a systematic methodology on a quarterly basis that considers available quantitative and qualitative evidence. If the cost or carrying value of an investment exceeds its estimated fair value, the Company evaluates, among other factors, general market conditions, credit quality of instrument issuers, the duration and extent to which the fair value is less than cost, and the Company’s intent and ability to hold, or plans or ability to sell. Fair value is estimated based on publicly available market information or other estimates determined by management. Investments are considered to be impaired when a decline in fair value is estimated to be other-than-temporary. Acacia reviews impairments associated with its investments in marketable securities and determines the classification of any impairment as temporary or other-than-temporary. An impairment is deemed other-than-temporary unless (a) Acacia has the ability and intent to hold an investment for a period of time sufficient for recovery of its carrying amount and (b) positive evidence indicating that the investment’s carrying amount is recoverable within a reasonable period of time outweighs any evidence to the contrary. All available evidence, both positive and negative, is considered to determine whether, based on the weight of such evidence, the carrying amount of the investment is recoverable within a reasonable period of time. For investments classified as available-for-sale, unrealized losses that are other-than-temporary are recognized in the consolidated statements of operations.

Patents. Patents includes the cost of patents or patent rights (hereinafter, collectively “patents”), acquired from third-parties or acquired in connection with business combinations. Patent acquisition costs are amortized utilizing the straight-line method over their remaining economic useful lives, ranging from one to nine years .

Goodwill. Goodwill is tested for impairment at the reporting unit level (operating segment or one level below an operating segment) on an annual basis (December 31 for Acacia) and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying value. Acacia considers its market capitalization and the carrying value of its assets and liabilities, including goodwill, when performing its goodwill impairment test. When conducting its annual goodwill impairment assessment, the Company initially performs a qualitative evaluation of whether it is more likely than not that goodwill is impaired. If it is determined by a qualitative evaluation that it is more likely than not that goodwill is impaired, the Company then applies a two-step impairment test. The two-step impairment test first compares the fair value of the Company's reporting unit to its carrying or book value. If the fair value of the reporting unit exceeds its carrying value, goodwill is not impaired and the Company is not required to perform further testing. If the carrying value of the reporting unit exceeds its fair value, the Company determines the implied fair value of the reporting unit's goodwill and if the carrying value of the reporting unit's goodwill exceeds its implied fair value, then an impairment loss equal to the difference is recorded in the consolidated statement of operations.

Acacia uses the management approach, which designates the internal organization that is used by management for making operating decisions and assessing performance as the basis of Acacia’s reportable segments. Acacia’s intellectual property licensing and enforcement business constitutes its single reportable segment.

Income Taxes. Income taxes are accounted for using an asset and liability approach that requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in Acacia’s consolidated financial statements or consolidated tax returns. A valuation allowance is established to reduce deferred tax assets if all, or some portion, of such assets will more than likely not be realized.

The provision for income taxes for interim periods is determined using an estimate of Acacia’s annual effective tax rate, adjusted for discrete items, if any, that are taken into account in the relevant period. Each quarter, Acacia updates the estimate of the annual effective tax rate, and if the estimated tax rate changes, a cumulative adjustment is made.

As of June 30, 2013 , Acacia’s effective tax rate was approximately 40% , mainly comprised of U.S. federal and state incomes taxes, foreign withholding taxes and nondeductible permanent expenses. Acacia's effective tax rate for the six months ended June 30, 2012 , including the impact of discrete items, was 25% . Discrete items were primarily comprised of the benefit associated with the release of valuation allowance resulting from the acquisition of ADAPTIX, as described below. The tax provisions for the periods presented provides for the utilization (subject to certain limitations, if applicable) of the foreign taxes withheld as a credit against income tax expense calculated for financial statement purposes.

The deduction related to the exercise and vesting of equity-based incentive awards is available to offset taxable income (loss), if any, on Acacia’s future consolidated tax returns. Accordingly, the noncash tax expense calculated without the benefit related to the exercise and vesting of equity-based incentive awards totaling $847,000 and $10.9 million for the six months ended June 30, 2013 and 2012, respectively, was credited to additional paid-in capital, not taxes payable.

ACACIA RESEARCH CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

Release of Valuation Allowance . As of December 31, 2011, the Company maintained a full valuation allowance against its net deferred tax assets. The net deferred tax liability resulting from the acquisition of ADAPTIX created an additional source of income to utilize against Acacia's existing consolidated net deferred tax assets. Under the acquisition method of accounting, the impact on the acquiring company's deferred tax assets is recorded outside of acquisition accounting. In addition, the Company estimated that certain other deferred tax assets related to foreign tax credits and other state related deferreds, totaling approximately $1.9 million , were more likely than not realizable in future periods. Accordingly, the valuation allowance on the majority of Acacia's net deferred tax assets was released, resulting in an income tax benefit of approximately $10.2 million , recorded as a credit to income tax expense for the six months ended June 30, 2012 . Refer to Note 7 to these consolidated financial statements.

Tax expense included foreign withholding taxes withheld by the applicable foreign tax authority on revenue agreements executed with third party licensees domiciled in certain foreign jurisdictions totaling $1,555,000 and $3,730,000 , respectively, for the three and six months ended June 30, 2013 and $28,000 and $11,890,000 , respectively, for the three and six months ended June 30, 2012 .

3. EARNINGS (LOSS) PER SHARE

Earnings (Loss) Per Share. Basic earnings (loss) per share is computed based upon the weighted-average number of common shares outstanding, excluding unvested restricted stock. Diluted income (loss) per share is computed based upon the weighted-average number of common shares outstanding, including the dilutive effect of common stock equivalents outstanding during the periods. Potentially dilutive common stock equivalents primarily consist of employee stock options, unvested restricted stock, and restricted stock units (“Equity-based Incentive Awards”).

Potentially dilutive common shares from Equity-based Incentive Awards are determined by applying the treasury stock method to the assumed exercise of outstanding employee stock options, and the assumed vesting of outstanding unvested restricted stock and restricted stock units. The following table presents the weighted-average number of common shares outstanding used in the calculation of basic and diluted earnings (loss) per share:



	Three Months Ended June 30,		Six Months Ended June 30,
	2013	2012	2013	2012

Weighted-average common shares outstanding - basic	48,008,998	47,944,193	47,934,810	46,155,846
Dilutive effect of equity-based incentive awards	—	994,573	—	1,052,259
Weighted-average common shares outstanding - diluted	48,008,998	48,938,766	47,934,810	47,208,105

Anti-dilutive equity-based incentive awards excluded from the computation of diluted income (loss) per share	958,727	54,260	960,622	34,260

4. GOODWILL AND OTHER IDENTIFIABLE INTANGIBLE ASSETS

Acacia’s only identifiable intangible assets at June 30, 2013 and December 31, 2012 are patents and patent rights. Patent-related accumulated amortization totaled $91,658,000 and $69,850,000 as of June 30, 2013 and December 31, 2012 , respectively.

Acacia’s patents and patent rights have remaining estimated economic useful lives ranging from one to nine years . The weighted-average remaining estimated economic useful life of Acacia’s patents and patent rights is approximately seven years . The following table presents the scheduled annual aggregate amortization expense as of June 30, 2013 (in thousands):

Thereafter	103,496
Total	$	303,489

For the six months ended June 30, 2013 and 2012 , Acacia paid patent and patent rights acquisition costs totaling $6,260,000 and $40,435,000 (excluding the acquisition of ADAPTIX), respectively. The patents and patent rights acquired have estimated economic useful lives of approximately one to ten years . Included in net additions to capitalized patent costs during the six months ended June 30, 2013 and 2012 are accrued future patent acquisition costs totaling $8,508,000 and $10,200,000 , respectively. Accrued future patent acquisition costs are amortized over the estimated economic useful life of the related patents acquired.

Refer to Note 7 to these consolidated financial statements for additions to patents and goodwill in connection with Acacia’s acquisition of ADAPTIX and the related application of the acquisition method of accounting.

During the six months ended June 30, 2013 and 2012 , certain operating subsidiaries recovered up-front patent portfolio acquisition costs from applicable net licensing proceeds prior to the scheduled amortization of such up-front patent portfolio acquisition costs, resulting in the acceleration of amortization expense for the applicable patent related assets. Accelerated amortization expense related to the recovery of up-front patent acquisition costs totaled $142,000 and $612,000 , for the three and six months ended June 30, 2013 , respectively, and $0 and $442,000 , for the three and six months ended June 30, 2012, respectively.

During the six months ended June 30, 2013 , pursuant to the terms of the respective inventor agreements, certain Acacia operating subsidiaries elected to terminate their rights to patent portfolios, resulting in the acceleration of amortization expense for the patent-related assets totaling $956,000 for the six months ended June 30, 2013 .

5. COMMITMENTS AND CONTINGENCIES

Patent Enforcement and Other Litigation

Acacia is subject to claims, counterclaims and legal actions that arise in the ordinary course of business. Management believes that the ultimate liability with respect to these claims and legal actions, if any, will not have a material effect on Acacia’s consolidated financial position, results of operations or cash flows. Certain of Acacia’s operating subsidiaries are often required to engage in litigation to enforce their patents and patent rights. In connection with any of Acacia’s operating subsidiaries’ patent enforcement actions, it is possible that a defendant may request and/or a court may rule that an operating subsidiary has violated statutory authority, regulatory authority, federal rules, local court rules, or governing standards relating to the substantive or procedural aspects of such enforcement actions. In such event, a court may issue monetary sanctions against Acacia or its operating subsidiaries or award attorney’s fees and/or expenses to a defendant(s), which could be material.

6. STOCKHOLDERS’ EQUITY

In February 2012, Acacia raised gross proceeds of $225,000,000 through the sale of 6,122,000 shares of Acacia’s common stock at a price of $36.75 per share in a private placement offering with certain institutional accredited investors. Net proceeds, net of placement agent fees and estimated offering expenses, totaled approximately $218,983,000 . The net proceeds will continue to be used to finance future acquisitions of patents, other patent licensing vehicles and companies with patent assets, and for working capital and general corporate purposes.

On April 23, 2013, Acacia announced that its Board of Directors approved the adoption of a cash dividend policy that calls for the payment of an expected total annual cash dividend of $0.50 per common share, payable in the amount of $0.125 per share per quarter. Under the policy, the first quarterly cash dividend, totaling $6,149,000 , was paid on May 30, 2013 to shareholders of record at the close of business on May 3, 2013. In addition, on July 18, 2013, Acacia announced a second

ACACIA RESEARCH CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

quarterly cash dividend, payable in the amount of $0.125 per share, which will be paid on August 30, 2013, to shareholders of record at the close of business on August 1, 2013. Future cash dividends are expected to be paid on a quarterly basis and will be at the discretion of the Company's Board of Directors.

Repurchases of Common Stock

On November 16, 2012, Acacia's Board of Directors authorized a program for repurchases of shares of Acacia's outstanding common stock. Under the stock repurchase program, effective November 16, 2012, Acacia was authorized to purchase in the aggregate up to $100,000,000 of its outstanding common stock. On April 23, 2013, Acacia's Board of Directors approved an extension of the repurchase plan from May 15, 2013 until August 15, 2013. Repurchases may be made from time to time by Acacia in the open market or in block purchases in compliance with applicable SEC rules. Repurchases to date were made using existing cash resources and occurred in the open market. The authorization to repurchase shares presented an opportunity to reduce the outstanding share count and enhance stockholder value. Following are Acacia's monthly stock repurchases, all of which were purchased as part of the publicly announced plan or program:



	Total Number of Shares Purchased	Average Price paid per Share		Approximate Dollar Value of Shares that May Yet be Purchased under the Program

November 16, 2012 - November 30, 2012	256,262	$	21.58	$	94,470,000
December 1, 2012 - December 31, 2012	873,146	$	24.26	$	73,268,000
	1,129,408	$	23.65

The Company did not repurchase any shares during the three or six months ended June 30, 2013.

7. ACQUISITION

On January 12, 2012 (the “Acquisition Date”), pursuant to the terms and conditions of the Agreement and Plan of Merger dated as of November 22, 2011 (the “Merger Agreement”) among Acacia Research Group LLC (“ARG”), a wholly-owned subsidiary of Acacia, Apollo Patent Corp., a newly-formed, wholly-owned subsidiary of ARG (“Merger Sub”), ADAPTIX, a Delaware corporation, and Baker Communications Fund II (QP), L.P. solely in its capacity as shareholder representative, ARG completed its acquisition of ADAPTIX, which held no material assets other than its portfolio of patents and $10 million in cash, through a merger of Merger Sub with and into ADAPTIX, with ADAPTIX as the surviving corporation (the “Merger”). Upon completion of the Merger, the separate corporate existence of Merger Sub ceased and ADAPTIX became a wholly-owned subsidiary of ARG.

ADAPTIX, a pioneer in the development of 4G technologies for wireless systems, is an award-winning technology company long recognized in the industry as one of the first developers of cutting edge 4G wireless systems. With patents filed as early as 2000, ADAPTIX’s research and development efforts have resulted in one of the most significant intellectual property portfolios focused on 4G technologies. With its rapidly growing portfolio of 230 issued and pending patents in 13 countries, ADAPTIX’s innovations extend across a broad range of 4G technologies including OFDMA and MIMO.

The Merger was accounted for in accordance with the acquisition method of accounting under FASB ASC Topic 805, “ Business Combinations” (“Topic 805”). Topic 805 requires, among other things, that identifiable assets acquired and liabilities assumed be recognized at their fair values as of the Acquisition Date. Under the acquisition method of accounting, the purchase consideration is allocated to the assets acquired, including tangible assets, patents and other identifiable intangible assets and liabilities assumed, based on their estimated fair market values on the date of acquisition. Any excess purchase price after the initial allocation to identifiable net tangible and identifiable intangible assets is assigned to goodwill. Amounts attributable to patents are amortized using the straight-line method over the estimated economic useful life of the underlying patents.

The total consideration paid by ARG in connection with the Merger was approximately $160 million , in cash. Based on the total purchase consideration and the estimate of the assets acquired and the liabilities assumed by ARG as of the Acquisition Date, the purchase price allocation was as follows ($ amounts in thousands):



				Amortization Period	Annual Amortization
Assets Acquired and Liabilities Assumed:

Fair value of net tangible assets acquired	$	10,000
Intangible assets acquired - patents	150,000			10 years	$	15,000
Goodwill	30,149
Net deferred income tax liability	(30,149		)
Total	$	160,000

Amounts attributable to the patents acquired are being amortized using the straight-line method over an estimated weighted average economic useful life of the underlying patents, which is estimated to be approximately 10 years . Goodwill is calculated as the residual after recording the identifiable net assets acquired and associated net deferred tax assets and liabilities.

Management is responsible for determining the fair value of the tangible and identifiable intangible assets acquired and liabilities assumed as of the Acquisition Date. Management considered a number of factors, including reference to an analysis under Topic 805 solely for the purpose of allocating the purchase price to the assets acquired and liabilities assumed. The analysis included a discounted cash flow which estimated future net cash flows resulting from the licensing and enforcement of the patent portfolio based on information as of the date of acquisition, considering assumptions and estimates related to potential infringers of the patents, applicable industries, usage of the underlying patented technologies, estimated license fee revenues, contingent legal fee arrangements, other estimated costs, tax implications and other factors. A discount rate consistent with the risks associated with achieving the estimated net cash flows was used to estimate the present value of estimated net cash flows.

The Merger was treated for tax purposes as a nontaxable transaction and as such, the historical tax bases of the acquired assets and assumed liabilities, net operating losses, and other tax attributes of ADAPTIX were carried over. As a result, no new tax goodwill was created in connection with the Merger as there was no step-up to fair value of the underlying tax bases of the acquired net assets. Acquisition accounting includes the establishment of a net deferred tax asset or liability resulting from book tax basis differences related to assets acquired and liabilities assumed on the date of acquisition. Acquisition date deferred tax assets primarily relate to certain net operating loss carryforwards of ADAPTIX. Acquisition date deferred tax liabilities relate to specifically identified non-goodwill intangibles acquired. The estimated net deferred tax liability was determined as follows (amounts in thousands, except percent values):



	Book Basis		Tax Basis		Difference

Intangible assets acquired - patents	$	150,000	$	—	$	(150,000	)
Estimated acquired deferred tax assets (including net operating loss carryforwards) - ADAPTIX	—		63,860		63,860
Net deferred tax liability - pretax					(86,140		)
Estimated tax rate					35		%
Estimated net deferred tax liability					$	(30,149	)

Proforma adjustments and operating results for ADAPTIX for the period from January 1, 2012 to January 12, 2012, the date of acquisition, were not material.

8. SUBSEQUENT EVENTS

On July 18, 2013, Acacia announced that its Board of Directors approved a second quarterly cash dividend payable in the amount of $0.125 per share per quarter. The quarterly cash dividend will be paid on August 30, 2013 to shareholders of record at close of business on August 1, 2013. Future cash dividends are expected to be paid on a quarterly basis and will be at the discretion of the Company's Board of Directors.

9 . RECENT ACCOUNTING PRONOUNCEMENTS

ACACIA RESEARCH CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

Recently Adopted Accounting Pronouncements - Adopted Effective January 1, 2013.

In February 2013, the FASB issued a new accounting standard requiring an entity to report the effect of significant reclassifications out of accumulated other comprehensive income on the respective line items in net income if the amount being reclassified is required under U.S. Generally Accepted Accounting Principles ("U.S. GAAP") to be reclassified in its entirety to net income. For other amounts that are not required under U.S. GAAP to be reclassified in their entirety to net income in the same reporting period, an entity is required to cross-reference other disclosures required under U.S. GAAP that provide additional detail about those amounts. This pronouncement is effective prospectively for reporting periods beginning after December 15, 2012. The adoption of this standard did not have a material impact on the Company’s consolidated financial statements and related disclosures.

In December 2012, the FASB issued a new accounting standard that will require the Company to disclose information about offsetting and related arrangements to enable users of its financial statements to understand the effect of those arrangements on its financial position. The new guidance is effective for the Company's interim period ending March 31, 2013. The disclosures required are to be applied retrospectively for all comparative periods presented. The adoption of this standard did not have a material impact on the Company’s consolidated financial statements and related disclosures.

General

As used in this Quarterly Report on Form 10-Q, “we,” “us” and “our” refer to Acacia Research Corporation, a Delaware corporation, and/or its wholly and majority-owned and controlled operating subsidiaries. All intellectual property acquisition, development, licensing and enforcement activities are conducted solely by certain of Acacia Research Corporation’s wholly and majority-owned and controlled operating subsidiaries.

Our operating subsidiaries acquire, develop, license and otherwise enforce patented technologies. Our operating subsidiaries generate revenues and related cash flows from the granting of intellectual property rights for the use of, or pertaining to, patented technologies that our operating subsidiaries own or control. Our operating subsidiaries assist patent owners with the prosecution and development of their patent portfolios, the protection of their patented inventions from unauthorized use, the generation of licensing revenue from users of their patented technologies and, if necessary, with the enforcement against unauthorized users of their patented technologies.

We are a leader in licensing patented technologies and have established a proven track record of licensing success with over 1,295 license agreements executed to date across 157 of our technology licensing and enforcement programs. Currently, on a consolidated basis, our operating subsidiaries own or control the rights to over 274 patent portfolios, which include U.S. patents, and certain foreign counterparts covering technologies used in a wide variety of industries.

We were originally incorporated in California in January 1993 and reincorporated in Delaware in December 1999.

Executive Summary

Our operating activities for the periods presented were principally focused on continuing to build our market leadership position in patent acquisitions, development, licensing and enforcement.

During the three months ended June 30, 2013 , we reported revenues of $23.1 million from 43 new revenue agreements covering 28 different licensing programs, including 3 licensing programs generating initial revenues in the quarter. We increased our cash and investments to $320.1 million as of June 30, 2013 from $311.3 million as of December 31, 2012.

During the three months ended June 30, 2013 , we acquired control of 7 new patent portfolios and invested $10.8 million (including $8.5 million in future payments accrued as of June 30, 2013 ) in patent portfolio acquisition up-front advances.

During the three months ended June 30, 2013 , we acquired patents relating to energy efficiency in the commercial and residential markets, patents relating to automatic illumination in the automotive market, and patents in the technology sector relating to ink jet printing, high speed circuit interconnect and display control, content security in consumer electronics, PCs and mobile devices, and printer technologies. We also partnered with a major technology company for patents relating to microprocessor and memory technology.

We continue to see an acceleration in opportunities for partnering with companies in the technology, energy, medical technology and other sectors for the licensing of their patented technologies, and are also expanding our activity in international markets, both of which we expect will expand and diversify our future revenue generating opportunities. During the three months ended June 30, 2013 we expanded our management team with key hires of experienced intellectual property acquisition and licensing executives from industry that will facilitate our continued development of these growth areas.

Operating activities during the periods presented included the following:



	Three Months Ended June 30,				Six Months Ended June 30,
	2013		2012		2013		2012

Revenues (in thousands)	$	23,110	$	50,484	$	99,971	$	149,524
New agreements executed	43		38		72		78
Licensing and enforcement programs generating revenues	28		27		40		45
Licensing and enforcement programs with initial revenues	3		7		14		13
New patent portfolios	7		27		16		32
Cumulative number of licensing and enforcement programs generating revenues - inception to date	157		125		157		125

Our revenues historically have fluctuated quarterly, and can vary significantly, based on a number of factors including the following:


•	the dollar amount of agreements executed each period, which can be driven by the nature and characteristics of the technology or technologies being licensed and the magnitude of infringement associated with a specific licensee ;


•	the specific terms and conditions of agreements executed each period including the nature and characteristics of rights granted, and the periods of infringement or term of use contemplated by the respective payments;


•	fluctuations in the total number of agreements executed each period;


•	the timing, results and uncertainties associated with patent filings and other enforcement proceedings relating to our intellectual property rights;


•	the relative maturity of licensing programs during the applicable periods; and


•	other external factors.

Although revenues from one or more of our patents or patent portfolios may be significant in a specific reporting period, we believe that none of our individual patents or patent portfolios is individually significant to our licensing and enforcement business as a whole.

We measure and assess the performance and growth of the patent licensing and enforcement businesses conducted by our operating subsidiaries based on consolidated revenues (including other operating income) recognized across all of our technology licensing and enforcement programs on a trailing twelve-month basis.

Overview - Three months ended June 30, 2013 compared with the three months ended June 30, 2012


•	Revenues decreased $27.4 million , or 54% , to $23.1 million , as compared to $50.5 million in the comparable prior year quarter.


•	Cost of Revenues and Other Operating Expenses:

◦

Inventor royalties and contingent legal fees, on a combined basis, decreased $6.5 million , or 40% , as compared to the 54% decrease in related revenues for the same periods, due primarily to a significantly higher percentage of revenues generated during the three months ended June 30, 2012 having lower or no contingent legal fee arrangement obligations, as compared to the revenues generated during the three months ended June 30, 2013 .

◦

Litigation and licensing expenses-patents increased $4.7 million , or 88% , to $9.9 million , due primarily to an increase in strategic patent portfolio prosecution costs, an increase in international enforcement costs, and higher net levels of litigation support and third-party technical consulting expenses associated with our continued investment in ongoing and new licensing and enforcement programs commenced since the end of the comparable prior year quarter. We expect patent-related legal expenses to continue to fluctuate period to period in connection with our current and future patent acquisition, development, licensing and enforcement activities.


◦	Amortization of patents increased $7.2 million , or 133% , to $12.6 million , due primarily to amortization expense related to new patent portfolios acquired since June 30, 2012 totaling $4.0 million and an increase in scheduled patent amortization for patent portfolios acquired in the latter portion of the prior year quarter totaling $2.1 million .


◦	Marketing, general and administrative expenses increased $1.3 million , or 11% , to $13.2 million , due primarily to a net increase in personnel related costs and minor increases in non-cash stock compensation expense, corporate facilities and general and administrative costs.


•	Our effective tax rate was approximately 40% and 35% for the three months ended June 30, 2013 and 2012, respectively. The effective tax rate for the three months ended June 30, 2012 includes non-cash tax expense of $3.2 million was credited to additional-paid-in capital, not taxes payable. Refer to “Comparison of Results of Operations” below for additional information.

Overview - Six months ended June 30, 2013 compared with the six months ended June 30, 2012


•	Revenues decreased $49.6 million , or 33% , to $100.0 million , as compared to $149.5 million in the comparable prior year period.


•	Cost of Revenues and Other Operating Expenses:

◦

Inventor royalties and contingent legal fees, on a combined basis, increased $15.6 million , or 57% , as compared to the 33% decrease in related revenues for the same periods, due primarily to a significantly higher percentage of revenues generated during the six months ended June 30, 2012 having no inventor royalty obligations (i.e. patent portfolio owned outright without back-end royalty obligation) or contingent legal fee arrangement obligations (i.e. revenues generated without litigation), as compared to the revenues generated during the six months ended June 30, 2013 .

◦

Litigation and licensing expenses-patents increased $10.9 million , or 126% , to $19.6 million , due primarily to an increase in strategic patent portfolio prosecution costs, an increase in international enforcement costs, and higher net levels of litigation support and third-party technical consulting expenses associated with our continued investment in ongoing and new licensing and enforcement programs commenced since the end of the comparable prior year period.


◦	Amortization of patents increased $13.8 million , or 131% , to $24.3 million , due primarily to amortization expense related to new patent portfolios acquired since June 30, 2012 totaling $8.2 million and an increase in scheduled patent amortization for patent portfolios acquired in the latter portion of the prior year period totaling $4.5 million .


◦	Marketing, general and administrative expenses increased $1.4 million , or 5% , to $27.0 million , due primarily to a net increase in licensing, business development, and engineering personnel since the end of the prior year quarter, and minor increases in non-cash stock compensation expense, corporate facilities and general and administrative costs.


•	Our effective tax rate was approximately 41% and 25% for the six months ended June 30, 2013 and 2012, respectively. The effective tax rate for the six months ended June 30, 2012 includes a benefit of $10.2 million associated with the release of valuation allowance resulting from the acquisition of ADAPTIX, as described at Note 2 to the consolidated financial statements elsewhere herein.

Acquisition of ADAPTIX, Inc.

On January 12, 2012, a wholly owned operating subsidiary of ours completed its acquisition of ADAPTIX, which held no material assets other than its portfolio of patents and $10 million in cash, through a merger with and into ADAPTIX, with ADAPTIX as the surviving corporation. Upon completion of the merger, ADAPTIX became a wholly-owned subsidiary of our operating subsidiary. The total consideration paid in connection with the merger was approximately $160 million, paid in cash.

ADAPTIX, a pioneer in the development of 4G technologies for wireless systems, is an award-winning technology company long recognized in the industry as one of the first developers of cutting edge 4G wireless systems. With patents filed as early as 2000, ADAPTIX’s research and development efforts have resulted in one of the world’s most significant intellectual property portfolios focused on 4G technologies. With its rapidly growing portfolio of 230 issued and pending patents in 13 countries, ADAPTIX’s innovations extend across a broad range of 4G technologies including OFDMA and MIMO.

Investments in Patent Portfolios

We also measure and assess the performance and growth of the patent licensing and enforcement businesses conducted by our operating subsidiaries based on the number of patent portfolios owned or controlled by our operating subsidiaries on a consolidated basis. As of June 30, 2013 , December 31, 2012 , and June 30, 2012 , on a consolidated basis, our operating subsidiaries owned or controlled the rights to approximately 274 , 250 and 238 patent portfolios, respectively, which include U.S. patents and certain foreign counterparts, covering technologies used in a wide variety of industries.

During the six months ended June 30, 2013 , certain of our operating subsidiaries continued to execute their business strategy in the area of patent portfolio acquisitions, including the acquisition of, or the acquisition of the rights to, 16 patent portfolios covering a variety of applications, including the following:


•	In January 2013, obtained a patent relating to core fiber optic network architectures.


•	In January 2013, obtained rights to a patent portfolio relating to oil and gas production and will share licensing revenue with the patent owner. The portfolio is comprised of 4 U.S. and 27 foreign patents that relate to polymer-based drilling fluids which are widely used in the drilling of oil and gas wells.


•	In January 2013, acquired patents relating to vascular device technology.


•	In January 2013, acquired patents relating to oil and gas production. The patents relate to solids separation technology which addresses removal of solids from drilling fluids used in oil and gas wells.

Refer to “Liquidity and Capital Resources” below for information regarding the impact of patent and patent rights acquisitions on the consolidated financial statements for the periods presented.

As of June 30, 2013 , certain of our operating subsidiaries had several option agreements with third-party patent portfolio owners regarding the potential acquisition of additional patent portfolios. Future patent portfolio acquisitions will continue to expand and diversify our future revenue generating opportunities.

Enforcement Considerations

The pursuit of enforcement actions in connection with our licensing and enforcement programs can involve certain risks and uncertainties, including the following:

•

Increases in patent-related legal expenses, including, but not limited to, increases in costs billed by outside legal counsel for discovery, depositions, economic analyses, damages assessments, expert witnesses and other consultants, case-related audio/video presentations and other litigation support and administrative costs, could increase our operating costs and decrease our revenue generating opportunities;


•	Our patented technologies and enforcement actions are complex, and, as a result, we may be required to appeal adverse decisions by trial courts in order to successfully enforce our patents;


•	New legislation, regulations or rules related to enforcement actions could significantly increase our operating costs and decrease our revenue generating opportunities; and


•	Courts may rule that our subsidiaries have violated certain statutory, regulatory, federal, local or governing rules or standards by pursuing such enforcement actions, which may expose us and our operating subsidiaries to material liabilities, which could harm our operating results and our financial position.

Critical Accounting Estimates

Our unaudited interim consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America. Preparation of these consolidated statements requires management to make judgments and estimates. Some accounting policies have a significant impact on amounts reported in these consolidated financial statements. A summary of significant accounting policies and a description of accounting policies that are considered critical may be found in the audited consolidated financial statements and notes thereto and under the caption “Management’s Discussion and Analysis of Financial Condition and Results of Operations - Critical Accounting Policies” included in our Annual Report on Form 10-K for the year ended December 31, 2012 .

Amortization of patents	12,578		5,393		24,308		10,519

Litigation and Licensing Expenses - Patents. Litigation and licensing expenses-patents include patent-related prosecution and enforcement costs incurred by outside patent attorneys engaged on an hourly basis and the out-of-pocket expenses incurred by law firms engaged on a contingent fee basis. Litigation and licensing expenses-patents also includes licensing and enforcement related third-party patent research, development, consulting, and other costs incurred in connection with the licensing and enforcement of patent portfolios. Litigation and licensing expenses-patents fluctuate from period to period based on patent litigation, enforcement and prosecution activity associated with ongoing licensing and enforcement programs and the timing of the commencement of new licensing and enforcement programs in each period.

Litigation and licensing expenses-patents increased for the periods presented due primarily to an increase in strategic patent portfolio prosecution costs, an increase in international enforcement costs, and higher net levels of patent portfolio litigation, litigation support, prosecution, third-party technical consulting and professional expert expenses associated with our continued investment in ongoing and new licensing and enforcement programs commenced since the end of the comparable prior year quarter. We expect patent-related legal expenses to continue to fluctuate period to period based on the factors summarized above, in connection with upcoming scheduled and/or anticipated trial dates and our current and future patent acquisition, development, licensing and enforcement activities.

Amortization of Patents . The change in amortization expense for the periods presented was due to the following:

•

Our effective tax rates for the three and six months ended June 30, 2013 were approximately 40% and 41%, respectively, mainly comprised of U.S. federal and state incomes taxes, foreign withholding taxes and nondeductible permanent expenses. The effective tax rate for the six months ended June 30, 2012 , included the impact of $10.2 million of tax benefits recognized resulting from the release of valuation allowance on the majority of our net deferred tax assets in the first quarter of 2012, as described at Note 2 to the consolidated financial statements elsewhere herein.


•	Noncash tax expense calculated without the excess benefit related to the exercise and vesting of equity-based incentive awards, which was credited to additional paid-in capital, not taxes payable, totaled $138,000 and $847,000 for the three and six months ended June 30, 2013 , respectively, and $3.2 million and $10.9 million for the three and six months ended June 30, 2012 , respectively.

Liquidity and Capital Resources

General

Our primary sources of liquidity are cash, cash equivalents and investments on hand generated from our operating activities and proceeds from recent equity financings. Refer to " Cash Flows from Financing Activities " below for information regarding recent equity financings. We retain broad discretion over the use of the net proceeds from recent offerings and intend to use the net proceeds for operations and for other general corporate purposes, including, but not limited to, working capital, strategic acquisitions and other transactions.

Our management believes that our cash and cash equivalent balances, investments, anticipated cash flows from operations, and other external sources of available credit, will be sufficient to meet our cash requirements through at least August 2014 and for the foreseeable future. We may, however, encounter unforeseen difficulties that may deplete our capital resources more rapidly than anticipated, including those set forth under the caption “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2012 . Any efforts to seek additional funding could be made through issuances of equity or debt, or other external financing. However, additional funding may not be available on favorable terms, or at all. The capital and credit markets have experienced extreme volatility and disruption since late 2007, and the volatility and impact of the disruption has continued into 2013. At times during this period, the volatility and disruption has reached unprecedented levels. In several cases, the markets have exerted downward pressure on stock prices and credit capacity for certain issuers, and the commercial paper markets may not be a reliable source of short-term financing for us. If we fail to obtain additional financing when needed, we may not be able to execute our business plans and our business, conducted by our operating subsidiaries, may suffer.

Cash, Cash Equivalents and Investments

Our consolidated cash and cash equivalents and investments on hand totaled $320.1 million at June 30, 2013 , compared to $311.3 million at December 31, 2012 . The net change in cash and cash equivalents for the periods presented was comprised of the following (in thousands):



	Six Months Ended June 30,
	2013			2012

Net cash provided by (used in):
Operating activities	$	18,104		$	63,405
Investing activities	(87,858		)	(313,113		)
Financing activities	(3,141		)	231,841

Cash Flows from Operating Activities. Cash receipts from licensees for the six months ended June 30, 2013 decreased to $93.0 million, from $141.6 million in the comparable 2012 period, primarily reflecting the net decrease in revenues for the same periods, as discussed above, and an increase in quarter end accounts receivable from licensees related to agreements executed during the three months ended June 30, 2013 . Cash outflows from operations for the six months ended June 30, 2013 decreased to $64.4 million, as compared to $83.7 million in the comparable 2012 period, primarily due to the net impact of the timing of cash receipts from licensees and related payments of inventor royalties and contingent legal fees, and the timing of payments to other third-parties in the ordinary course, for the same periods. Refer to "Working Capital" below for additional information.

In February 2012, we raised net proceeds of $219.0 million through the sale of 6,122,000 shares of our common stock at a price of $36.75 per share in a private placement offering with certain institutional accredited investors. The net proceeds will continue to be used to finance future acquisitions of patents, other patent licensing vehicles and companies with patent assets, and for working capital and general corporate purposes.

On April 23, 2013, we announced that our Board of Directors approved the adoption of a cash dividend policy that calls for the payment of an expected total annual cash dividend of $0.50 per common share, payable in the amount of $0.125 per share per quarter. Under the policy, the first of the quarterly cash dividends, totaling $6,149,000 , were paid on May 30, 2013 to shareholders of record at the close of business on May 3, 2013.

Working Capital

Working capital at June 30, 2013 increased to $309.8 million , compared to $302.6 million at December 31, 2012 . Consolidated accounts receivable from licensees increased to $16.8 million at June 30, 2013 , compared to $9.8 million at December 31, 2012 . Consolidated royalties and contingent legal fees payable increased to $20.0 million at June 30, 2013 , compared to $12.5 million at December 31, 2012 .

The majority of accounts receivable from licensees at June 30, 2013 were collected or scheduled to be collected in the third quarter of 2013, in accordance with the terms of the related underlying agreements. The majority of royalties and contingent legal fees payable are scheduled to be paid in the third or fourth quarter of 2013, subsequent to receipt by us of the related fee payments from licensees, in accordance with the underlying contractual arrangements.

Share Repurchase Program. On November 16, 2012, we announced that our Board of Directors authorized a program for repurchases of shares of our outstanding common stock. Under the stock repurchase program, effective November 16, 2012, we are authorized to purchase in the aggregate up to $100 million of our common stock through the period ending May 15, 2013. Repurchases may be made from time to time by us in the open market or in block purchases in compliance with applicable SEC rules. From the effective date through December 31, 2012, we acquired 1,129,408 shares of our common stock at an average price of $23.65 per share. We repurchased shares through December 14, 2012 (trading window close date pursuant to applicable regulations) in the open market using existing cash resources. We did not repurchase any shares during the three or six months ended June 30, 2013 . On April 23, 2013, our Board of Directors approved an extension of the stock repurchase program from May 15, 2013 until August 15, 2013.

Subsequent Event. On July 18, 2013, Acacia announced a second quarterly cash dividend, payable in the amount of $0.125 per share, which will be paid on August 30, 2013, to shareholders of record at the close of business on August 1, 2013. Future cash dividends are expected to be paid on a quarterly basis and will be at the discretion of the Company's Board of Directors.

Off-Balance Sheet Arrangements

We have not entered into off-balance sheet financing arrangements, other than operating leases. We have no significant commitments for capital expenditures in 2013 . We have no committed lines of credit or other committed funding or long-term debt. The following table lists our known contractual obligations and future cash commitments as of June 30, 2013 (in thousands):



	Payments Due by Period (In thousands)

Uncertain Tax Positions . At June 30, 2013 , we had total unrecognized tax benefits of approximately $2,127,000 , including a recorded noncurrent liability of $85,000, related to unrecognized tax benefits primarily associated with state taxes. No interest and penalties have been recorded for the unrecognized tax benefits as of December 31, 2012. If recognized, approximately $2,127,000 would impact our effective tax rate. We do not expect that the liability for unrecognized tax benefits will change significantly within the next 12 months. Activity related to the gross unrecognized tax benefits for the year ended December 31, 2012 was as follows (in thousands):



Balance at January 1, 2012	$	85

Item 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The primary objective of our investment activities is to preserve principal while concurrently maximizing the income we receive from our investments without significantly increasing risk. Some of the securities that we invest in may be subject to interest rate risk and/or market risk. This means that a change in prevailing interest rates, with respect to interest rate risk, or a change in the value of the United States equity markets, with respect to market risk, may cause the principal amount or market value of the investments to fluctuate. For example, if we hold a security that was issued with a fixed interest rate at the then-prevailing rate and the prevailing interest rate later rises, the current value of the principal amount of our investment may decline. To minimize these risks in the future, we intend to maintain our portfolio of cash equivalents and short-term investments in a variety of securities, including commercial paper, money market funds, high-grade corporate bonds, government and non-government debt securities and certificates of deposit.

At June 30, 2013 , our short-term investments were comprised of AAA rated money market funds that invest in first-tier only securities, which primarily include domestic commercial paper, securities issued or guaranteed by the U.S. government or its agencies, U.S. bank obligations, and fully collateralized repurchase agreements (included in cash and cash equivalents in the accompanying consolidated balance sheets) and direct investments in highly liquid, AAA, U.S. government securities.

In general, money market funds are not subject to market risk because the interest paid on such funds fluctuates with the prevailing interest rate. Accordingly, a 100 basis point increase in interest rates or a 10% decline in the value of the United States equity markets would not be expected to have a material impact on the value of such money market funds. Investments in U.S. government fixed income securities are subject to interest rate risk and will decline in value if interest rates increase. However, due to the relatively short duration of our investment portfolio, an immediate 10% change in interest rates would have no material impact on our financial condition, results of operations or cash flows. Declines in interest rates over time will, however, reduce our interest income.

Item 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Our management, with the participation and under the supervision of our chief executive officer and chief financial officer, has evaluated the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) promulgated under the Securities Exchange Act of 1934, as amended, or the Exchange Act) as of the end of the period covered by this quarterly report. Based on that evaluation, our chief executive officer and our chief financial officer have concluded that our disclosure controls and procedures were effective as of the end of the period covered by this quarterly report to ensure that the information required to be disclosed by us in the reports that we file or submit under the Exchange Act is accumulated and communicated to our management, including our chief executive officer and chief financial officer, as appropriate to allow timely decisions regarding required disclosure, and that such information is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms.

Changes in Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting that occurred during our last fiscal quarter (the quarter ended June 30, 2013 ) that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
