	The accompanying unaudited consolidated financial statements of DTS, Inc. (the "Company") have been prepared in accordance with accounting principles generally accepted in the United States of America (US GAAP) and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and notes required by US GAAP for complete financial statements. In the opinion of management, the unaudited consolidated financial statements reflect all adjustments considered necessary for a fair statement of the Company's financial position at June 30, 2014, and the results of operations and cash flows for the periods presented. All significant intercompany transactions have been eliminated in consolidation. Operating results for interim periods are not necessarily indicative of the results that may be expected for the full year. The information included in this Form 10-Q should be read in conjunction with the consolidated financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2013, filed with the Securities and Exchange Commission on March 20, 2014.
	The preparation of financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosures of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ materially from those estimates.

	In July 2013, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2013-11, "Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists". This ASU provides guidance regarding when an unrecognized tax benefit should be classified as a reduction to a deferred tax asset or when it should be classified as a liability in the consolidated balance sheet. This ASU is effective prospectively for fiscal years, and interim periods within those years, beginning after December 15, 2013. The Company fully adopted this ASU in the first quarter of 2014. As of June 30, 2014, the Company has presented $4,856 of unrecognized tax benefits as a reduction to deferred tax assets on the consolidated balance sheet.
	In May 2014, the FASB issued ASU 2014-09, "Revenue from Contracts with Customers (Topic 606)". This ASU outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. For public entities, this ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016. Early adoption is not permitted. Entities have the option of applying either a full retrospective approach or a modified approach to adopt the guidance in the ASU. The Company is evaluating the potential impact of adoption of this ASU on its consolidated financial statements.

Fair Value Measurements	'
	Note 4—Fair Value Measurements
	The Company's investments are required to be measured and recorded at fair value on a recurring basis. The Company's contingent consideration related to its acquisition of assets from Phorus, Inc. and Phorus, LLC (collectively "Phorus") is also measured and recorded at fair value on a recurring basis until it can be determined whether or not any future payments will be made. Increases or decreases in the fair value of contingent consideration can result from accretion of the liability due to the passage of time, changes in the timing and amount of revenue estimates, changes in discount rates, or payments.
	The Company obtained the fair value of its available-for-sale securities, which are not in active markets, from a third-party professional pricing service using quoted market prices for identical or comparable instruments, rather than direct observations of quoted prices in active markets. The Company's professional pricing service gathers observable inputs for all of its fixed income securities from a variety of industry data providers (e.g., large custodial institutions) and other third-party sources. Once the observable inputs are gathered, all data points are considered and the fair value is determined. The Company validates the quoted market prices provided by its primary pricing service by comparing their assessment of the fair values against the fair values provided by its investment managers. The Company's investment managers use similar techniques to its professional pricing service to derive pricing as described above. As all significant inputs were observable, derived from observable information in the marketplace or supported by observable levels at which transactions are executed in the marketplace, the Company has classified its available-for-sale securities within Level 2 of the fair value hierarchy.
	The Company classifies the fair value of the contingent consideration liability within Level 3 of the fair value hierarchy, as the fair value is based upon unobservable inputs supported by little or no market activity. As of June 30, 2014, the Company measured the fair value of contingent consideration using an income approach, based on an analysis of projected cash flows using a discount rate of 17%. The Company estimated the fair value of the contingent consideration to be $1,100 as of June 30, 2014, and accordingly recognized $100 within operating expenses in the consolidated statements of operations for the three and six months ended June 30, 2014. Considerable judgment is required in the assumptions used in fair value measurements. Accordingly, use of different assumptions, such as significant increases or decreases in estimated revenues, cash flows or the discount rate, could result in materially different fair value estimates. For additional information, refer to Note 6 "Commitments and Contingencies".
	The Company's financial assets and liabilities, measured at fair value on a recurring basis, were as follows:

Commitments and Contingencies	'
	Note 6—Commitments and Contingencies
	In the normal course of business, the Company makes certain indemnities, commitments and guarantees under which the Company may be required to make payments in relation to certain transactions. These indemnities, commitments and guarantees include, among others, intellectual property indemnities to customers in connection with the sale of products and licensing of technologies, indemnities for liabilities associated with the infringement of other parties' technology based upon the Company's products and technologies, guarantees of timely performance of the Company's obligations, and indemnities to the Company's directors and officers to the maximum extent permitted by law. The duration of these indemnities, commitments and guarantees varies, and in certain cases, is indefinite. The majority of these indemnities, commitments and guarantees do not provide for any limitation of the maximum potential future payments that the Company could be obligated to make. The Company has not recorded a liability for these indemnities, commitments or guarantees in the accompanying consolidated balance sheets, as future payment is currently not probable.
	Under certain existing contractual rights arrangements, the Company may be obligated to pay up to approximately $7,500 over an estimated period of three years if certain milestones are achieved.
	In connection with the acquisition of Phorus, contingent consideration of up to $500 could be due and payable at the end of 2014, and up to $1,000 could be due and payable at the end of 2015.
	In the first quarter of 2014, the Company implemented certain staffing changes to allow the Company to facilitate further investments in growth markets. In connection with these changes, the Company recorded severance and related costs of $1,118, all of which were paid as of June 30, 2014.

Income Taxes	'
	Note 7—Income Taxes
	For the three and six months ended June 30, 2014, the Company's effective tax rate was approximately (17)% and (42)%, respectively. The effective tax rate for the three months ended June 30, 2014 differed from the US statutory rate of 35% primarily due to a tax benefit of $3,326 associated with the effective settlement of a federal tax audit. The effective tax rate for the six months ended June 30, 2014 also differed from the US statutory rate primarily due to a net tax benefit of $3,510 associated with a special one-time transfer of certain Japan and Taiwan intellectual property licensing rights transacted on January 1, 2014.
	As of June 30, 2014 and December 31, 2013, the Company's uncertain tax positions were $10,018 and $9,701, respectively, of which $5,162 and $1,713, respectively, were recorded in other long-term liabilities. The remaining amounts were recorded as a reduction to long-term deferred tax assets, pursuant to ASU 2013-11. The increase in uncertain tax positions was primarily related to the Company's transfer pricing with one of its foreign subsidiaries, state research and development tax credits, and the California income apportionment methodology. The current 2009 to 2011 US federal income tax audit with the Internal Revenue Service (IRS) had no impact on the Company's unrecognized tax benefits. The Company does not expect, or cannot quantify with any practicable certainty, any material increase or decrease to its unrecognized tax benefits within the next twelve months. To the extent that any of the Company's uncertain tax positions are not able to be resolved in a favorable manner, it may have a negative impact on the effective tax rate. Additionally, any settlement may impact the Company's effective tax rate. The Company believes its accruals for uncertain tax positions are adequate for all open years, based on the assessment of many factors including past experience and interpretations of tax law applied to the facts of each matter. Inherent uncertainties exist in estimating accruals for uncertain tax positions due to the progress of income tax audits and changes in tax law, both legislated and concluded through the various jurisdictions' tax court systems.
	The Company may, from time to time, be assessed interest or penalties by major tax jurisdictions, although any such assessments historically have been minimal and immaterial to the Company's financial statements. Interest expense and penalties related to income taxes are included in income tax expense.
	The Company, or one of its subsidiaries, files income tax returns in the US and other foreign jurisdictions. With few exceptions, the Company is no longer subject to US federal income tax examinations by tax authorities for years prior to 2009. The IRS is examining the Company's 2009 to 2011 federal income tax returns, including certain prior period carryforwards. In addition, the California Franchise Tax Board (FTB) is conducting a state tax examination for the years 2009 and 2010. Significant judgment is required in determining the consolidated provision (benefit) for income taxes as the Company considers its worldwide taxable earnings and the impact of the audit process conducted by various tax authorities. The final outcome of tax audits by any foreign jurisdictions, the IRS, the FTB, and various state governments could differ materially from that which is reflected in the consolidated financial statements.
	Licensing revenue is recognized gross of withholding taxes that are remitted by the Company's licensees directly to their local tax authorities. For the three months ended June 30, 2014 and 2013, withholding taxes were $562 and $1,139, respectively. For the six months ended June 30, 2014 and 2013, withholding taxes were $2,095 and $2,389, respectively.

	Note 8—Stock-Based Compensation
	On March 13, 2014, the Compensation Committee of the Company's Board of Directors granted 134 performance-based restricted stock units (PSUs) to certain employees under the DTS, Inc. 2012 Equity Incentive Plan. The PSUs will vest in two equal installments upon achievement of certain internal performance goals, with one-half vesting on February 15, 2016 and the remaining vesting on February 15, 2017, in each case assuming the specified performance goals are achieved and so long as the employee has met the service conditions. Achievement of the performance goals will be measured as of December 31, 2015. Each PSU represents the contingent right to receive between zero and two shares of the Company's common stock upon vesting, subject to the level of achievement of the specified performance goals. Any portion of the PSUs that do not vest due to performance below the minimum required level for vesting will be forfeited.
	The PSUs had a grant-date fair value of $20.37, which is equal to the market value of the Company's common stock on the date of grant. The related compensation expense is calculated using the number of shares of common stock expected to vest based on the probable level of achievement of the performance goals. Compensation expense is recognized over the requisite service period, and will be adjusted in subsequent reporting periods if the Company's assessment of the probable level of achievement of the performance goals changes. For the three and six months ended June 30, 2014, compensation expense for PSUs was $395 and $429, respectively. Considerable judgment is required in the assessment of the probable level of achievement of the performance goals. Accordingly, use of different assumptions or estimates could result in materially different compensation expense.

Diluted net income per common share is calculated by dividing net income by the sum of the weighted average number of common shares outstanding plus the dilutive effect of any unvested restricted stock, outstanding stock options, any unvested PSUs for which the performance conditions have been satisfied at the reporting date, and the Company's employee stock purchase plan (ESPP) using the treasury stock method. Due to the net loss for the three and six months ended June 30, 2013, all potential common shares were excluded from the diluted shares outstanding for these periods.
	The computation of basic and diluted net income (loss) per common share is as follows:
