Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Principles of Consolidation

The consolidated financial statements include our accounts and those of our wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in the consolidated financial statements.

Reclassifications

Certain prior period amounts in the accompanying consolidated financial statements have been reclassified to conform to the current year presentation. These reclassifications had no effect on previously reported net income or stockholders' equity.

Estimates and Assumptions

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. On an on-going basis, we evaluate our estimates and assumptions, including those related to revenue recognition, allowances for sales returns and doubtful accounts, inventory valuation, our review for impairment of long-lived assets, intangible assets and goodwill, income taxes and stock-based compensation expense. Actual results may differ from these assumptions and estimates, and they may be adjusted as more information becomes available. Any adjustment may be material.

Revenue Recognition

We recognize revenue on the sale of products when title of the goods has transferred, there is persuasive evidence of an arrangement (such as when a purchase order is received from the customer), the sales price is fixed or determinable, and collectability is reasonably assured.

The provision recorded for estimated sales returns is deducted from gross sales to arrive at net sales in the period the related revenue is recorded. These estimates are based on historical sales returns, analysis of credit memo data and other known factors. We have no obligations after delivery of our products other than the associated warranties. See Note 13 for further information concerning our warranty obligations.

We accrue for discounts and rebates based on historical experience and our expectations regarding future sales to our customers. Accruals for discounts and rebates are recorded as a reduction to sales in the same period as the related revenues. Changes in such accruals may be required if future rebates and incentives differ from our estimates.

Trade accounts receivable are recorded at the invoiced amount and do not bear interest. Sales allowances are recognized as reductions of gross accounts receivable to arrive at accounts receivable, net if the sales allowances are distributed in customer account credits. See Note 4 for further information concerning our sales allowances.

Revenue for the sale of tooling is recognized when the related services have been provided, customer acceptance documentation has been obtained, the sales price is fixed or determinable, and collectability is reasonably assured.

We generate service revenue, which is paid monthly, as a result of providing consumer support programs to some of our customers through our call centers. These service revenues are recognized when services are performed, persuasive evidence of an arrangement exists (such as when a signed agreement is received from the customer), the sales price is fixed or determinable, and collectability is reasonably assured.

We license our intellectual property including our patented technologies, trademarks, and database of infrared codes. When our license fees are paid on a per unit basis we record license revenue when our customers ship a product incorporating our intellectual property, persuasive evidence of an arrangement exists, the sales price is fixed or determinable, and collectability is reasonably assured. When a fixed upfront license fee is received in exchange for the delivery of a particular database of infrared codes that represents the culmination of the earnings process, we record revenues when delivery has occurred, persuasive evidence of an arrangement exists, the sales price is fixed or determinable and collectability is reasonably assured. Revenue for term license fees is recognized on a straight-line basis over the effective term of the license when we cannot reliably predict in which periods, within the term of the license, the licensee will benefit from the use of our patented inventions.

We present all non-income government-assessed taxes (sales, use and value added taxes) collected from our customers and remitted to governmental agencies on a net basis (excluded from revenue) in our financial statements. The government-assessed taxes are recorded in other accrued expenses until they are remitted to the government agency.

Income Taxes

Income tax expense includes U.S. and foreign income taxes. We account for income taxes using the liability method. We record deferred tax assets and deferred tax liabilities on our balance sheet for expected future tax consequences of events recognized in our financial statements in a different period than our tax return using enacted tax rates that will be in effect when these differences reverse. We record a valuation allowance to reduce net deferred tax assets if we determine that it is more likely than not that the deferred tax assets will not be realized. A current tax asset or liability is recognized for the estimated taxes refundable or payable for the current year.

Accounting standards prescribe a recognition threshold and a measurement attribute for the financial statement recognition and measurement of the positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more likely than not to be sustained upon examination by taxing authorities. A "more likely than not" tax position is measured as the largest amount of benefit that is greater than fifty percent likely of being realized upon ultimate settlement, or else a full reserve is established against the tax asset or a liability is recorded. See Note 9 for further information concerning income taxes.

Research and Development

Research and development costs are expensed as incurred and consist primarily of salaries, employee benefits, supplies and materials.

Advertising

Advertising costs are expensed as incurred. Advertising expense totaled $1.2 million, $1.2 million, and $1.3 million for the years ended December 31, 2014, 2013 and 2012, respectively.

Shipping and Handling Fees and Costs

We include shipping and handling fees billed to customers in net sales. Shipping and handling costs associated with in-bound freight are recorded in cost of goods sold. Other shipping and handling costs are included in selling, general and administrative expenses and totaled $11.3 million, $11.3 million and $9.2 million for the years ended December 31, 2014, 2013 and 2012, respectively.

Stock-Based Compensation

We recognize the grant date fair value of stock-based compensation awards as expense, net of estimated forfeitures, in proportion to vesting during the requisite service period, which ranges from one to four years. Estimated forfeiture rates are based upon historical forfeitures.

We determine the fair value of restricted stock awards utilizing the average of the high and low trade prices of our Company's shares on the date they were granted.

The fair value of stock options granted to employees and directors is determined utilizing the Black-Scholes option pricing model. The assumptions utilized in the Black-Scholes model include risk-free interest rate, expected volatility, and expected life in years. The risk-free interest rate over the expected term is equal to the prevailing U.S. Treasury note rate over the same period. Expected volatility is determined utilizing historical volatility over a period of time equal to the expected life of the stock option. Expected life is computed utilizing historical exercise patterns and post-vesting behavior. The dividend yield is assumed to be zero since we have not historically declared dividends and do not have any plans to declare dividends in the future. See Note 16 for further information regarding stock-based compensation.

Foreign Currency Translation and Foreign Currency Transactions

We use the U.S. Dollar as our functional currency for financial reporting purposes. The functional currency for most of our foreign subsidiaries is their local currency. The translation of foreign currencies into U.S. Dollars is performed for balance sheet accounts using exchange rates in effect at the balance sheet dates and for revenue and expense accounts using the average exchange rate during each period. The gains and losses resulting from the translation are included in the foreign currency translation adjustment account, a component of accumulated other comprehensive income in stockholders' equity, and are excluded from net income. The portions of intercompany accounts receivable and accounts payable that are intended for settlement are translated at exchange rates in effect at the balance sheet date. Our intercompany foreign investments and long-term debt that are not intended for settlement are translated using historical exchange rates.

Transaction gains and losses generated by the effect of changes in foreign currency exchange rates on recorded assets and liabilities denominated in a currency different than the functional currency of the applicable entity are recorded in other income (expense), net. See Note 17 for further information concerning transaction gains and losses.

Earnings Per Share

Basic earnings per share is computed by dividing net income available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted earnings per share is computed by dividing net income by the weighted average number of common shares and dilutive potential common shares, including the dilutive effect of stock option and restricted stock awards, outstanding during the period. Dilutive potential common shares for all periods presented are computed utilizing the treasury stock method.

In the computation of diluted earnings per common share we exclude stock options with exercise prices greater than the average market price of the underlying common stock because their inclusion would be anti-dilutive. Furthermore, we exclude shares of restricted stock whose combined unamortized fair value and excess tax benefits are greater than the average market price of the underlying common stock during the period, as their effect would be anti-dilutive.

Financial Instruments

Our financial instruments consist primarily of cash and cash equivalents, accounts receivable, accounts payable, accrued liabilities and debt. The carrying value of our financial instruments approximates fair value as a result of their short maturities. See Notes 3, 4, 5, 8, 10, and 11 for further information concerning our financial instruments.

Cash and Cash Equivalents

Cash and cash equivalents include cash accounts and all investments purchased with initial maturities of three months or less. We attempt to mitigate our exposure to liquidity, credit and other relevant risks by placing our cash and cash equivalents with financial institutions we believe are high quality. These financial institutions are located in many different geographic regions. As part of our cash and risk management processes, we perform periodic evaluations of the relative credit standing of our financial institutions. We have not sustained credit losses from instruments held at financial institutions. See Note 3 for further information concerning cash and cash equivalents.

Allowance for Doubtful Accounts

We maintain an allowance for doubtful accounts for estimated losses resulting from the inability of our customers to make payments for products sold or services rendered. The allowance for doubtful accounts is based on a variety of factors, including credit reviews, historical experience, length of time receivables are past due, current economic trends and changes in customer payment behavior.

We also record specific provisions for individual accounts when we become aware of a customer's inability to meet its financial obligations to us, such as in the case of bankruptcy filings or deterioration in the customer's operating results or financial position. If circumstances related to a customer change, our estimates of the recoverability of the receivables would be further adjusted.

Inventories

Inventories consist of remote controls, audio-video accessories as well as the related component parts and raw materials. Inventoriable costs include materials, labor, freight-in and manufacturing overhead related to the purchase and production of inventories. We value our inventories at the lower of cost or market. Cost is determined using the first-in, first-out method. We attempt to carry inventories in amounts necessary to satisfy our customer requirements on a timely basis. See Note 5 for further information concerning our inventories and suppliers.

Product innovations and technological advances may shorten a given product's life cycle. We continually monitor our inventories to identify any excess or obsolete items on hand. We write-down our inventories for estimated excess and obsolescence in an amount equal to the difference between the cost of the inventories and estimated net realizable value. These estimates are based upon management's judgment about future demand and market conditions. Actual results may differ from management's judgments and additional write-downs may be required.

Property, Plant, and Equipment

Property, plant, and equipment are recorded at cost. The cost of property, plant, and equipment includes the purchase price of the asset and all expenditures necessary to prepare the asset for its intended use. We capitalize additions and improvements and expense maintenance and repairs as incurred. To qualify for capitalization, an asset, excluding computer equipment, must have a useful life greater than one year and a cost equal to or greater than $5,000 for individual assets or $5,000 for assets purchased in bulk. To qualify for capitalization, computer equipment, must have a useful life of greater than one year and a cost equal to or greater than $1,000 for individual assets or $5,000 for assets purchased in bulk.

We capitalize certain internal and external costs incurred to acquire or create internal use software, principally related to software coding, designing system interfaces and installation and testing of the software.

For financial reporting purposes, depreciation is calculated using the straight-line method over the estimated useful lives of the respective assets. When assets are retired or otherwise disposed of, the cost and accumulated depreciation are removed from the appropriate accounts and any gain or loss is included as a component of depreciation expense.

Estimated useful lives consist of the following:



Buildings	25-33 Years
Tooling and equipment	2-5 Years
Computer equipment	3-5 Years
Software	3-7 Years
Furniture and fixtures	5-8 Years
Leasehold and building improvements	Lesser of lease term or useful life (approximately 2 to 10 years)

See Note 6 for further information concerning our property, plant, and equipment.

Goodwill

We record the excess purchase price of net tangible and intangible assets acquired over their estimated fair value as goodwill. We evaluate the carrying value of goodwill on December 31 of each year and between annual evaluations if events occur or circumstances change that may reduce the fair value of the reporting unit below its carrying amount. Such circumstances may include, but are not limited to: (1) a significant adverse change in legal factors or in business climate, (2) unanticipated competition, or (3) an adverse action or assessment by a regulator.

When performing the impairment review, we determine the carrying amount of each reporting unit by assigning assets and liabilities, including the existing goodwill, to those reporting units. A reporting unit is defined as an operating segment or one level below an operating segment (referred to as a component). A component of an operating segment is deemed a reporting unit if the component constitutes a business for which discrete financial information is available, and segment management regularly reviews the operating results of that component. We have a single reporting unit.

To evaluate whether goodwill is impaired, we conduct a two-step quantitative goodwill impairment test. In the first step we compare the estimated fair value of the reporting unit to which the goodwill is assigned to the reporting unit's carrying amount, including goodwill. We estimate the fair value of our reporting unit based on income and market approaches. Under the income approach, we calculate the fair value of a reporting unit based on the present value of estimated future cash flows. Under the market approach, we estimate the fair value based on market multiples of enterprise value to EBITDA for comparable companies. If the carrying value of the net assets assigned to the reporting unit exceeds the fair value of the reporting unit, then we perform the second step of the impairment test in order to determine the implied fair value of the reporting unit's goodwill. To calculate the implied fair value of the reporting unit's goodwill, the fair value of the reporting unit is first allocated to all of the other assets and liabilities of that unit based on their fair values. The excess of the reporting unit's fair value over the amount assigned to its other assets and liabilities is the implied fair value of goodwill. An impairment loss would be recognized equal to the amount by which the carrying value of goodwill exceeds its implied fair value.

See Note 7 for further information concerning goodwill.

Long-Lived and Intangible Assets Impairment

Intangible assets consist principally of distribution rights, patents, trademarks, trade names, developed and core technologies, capitalized software development costs (see also Note 2 under the caption Capitalized Software Development Costs) and customer relationships. Capitalized amounts related to patents represent external legal costs for the application and maintenance of patents. Intangible assets are amortized using the straight-line method over their estimated period of benefit, ranging from one to fifteen years.

We assess the impairment of long-lived assets and intangible assets whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Factors considered important which may trigger an impairment review include the following: (1) significant underperformance relative to expected historical or projected future operating results; (2) significant changes in the manner or use of the assets or strategy for the overall business; (3) significant negative industry or economic trends and (4) a significant decline in our stock price for a sustained period.

We conduct an impairment review when we determine that the carrying value of a long-lived or intangible asset may not be recoverable based upon the existence of one or more of the above indicators of impairment. The asset is impaired if its carrying value exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset. In assessing recoverability, we must make assumptions regarding estimated future cash flows and other factors.

The impairment loss is the amount by which the carrying value of the asset exceeds its fair value. We estimate fair value utilizing the projected discounted cash flow method and a discount rate determined by our management to be commensurate with the risk inherent in our current business model. When calculating fair value, we must make assumptions regarding estimated future cash flows, discount rates and other factors.

See Notes 6 and 15 for further information concerning long-lived assets. See Note 7 for further information concerning intangible assets.

Capitalized Software Development Costs

Costs incurred to develop software for resale are expensed when incurred as research and development expense until technological feasibility has been established. We have determined that technological feasibility for our products is typically established when a working prototype is complete. Once technological feasibility is established, software development costs are capitalized until the product is available for general release to customers.

Capitalized software development costs are amortized on a product-by-product basis. Amortization is recorded in cost of sales and is the greater of the amounts computed using:


a.	the net book value at the beginning of the period multiplied by the ratio that current gross revenues for a product bear to the total of current and anticipated future gross revenues for that product; or


b.	the straight-line method over the remaining estimated economic life of the product including the period being reported on.

The amortization of capitalized software development costs begins when the related product is available for general release to customers. The amortization period is generally two years.

We compare the unamortized capitalized software development costs of a product to its net realizable value at each balance sheet date. The amount by which the unamortized capitalized software development costs exceed the product's net realizable value is written off. The net realizable value is the estimated future gross revenues of a product reduced by its estimated completion and disposal costs. Any remaining amount of capitalized software development costs are considered to be the cost for subsequent accounting periods and the amount of the write-down is not subsequently restored. See Note 7 for further information concerning capitalized software development costs.

Derivatives

Our foreign currency exposures are primarily concentrated in the Argentinian Peso, Brazilian Real, British Pound, Chinese Yuan Renminbi, Euro, Hong Kong Dollar, Indian Rupee, and Singapore Dollar. We periodically enter into foreign currency exchange contracts with terms normally lasting less than nine months to protect against the adverse effects that exchange-rate fluctuations may have on our foreign currency-denominated receivables, payables, cash flows and reported income. We do not enter into financial instruments for speculation or trading purposes.

The derivatives we enter into have not qualified for hedge accounting. The gains and losses on both the derivatives and the foreign currency-denominated balances are recorded as foreign exchange transaction gains or losses and are classified in other income (expense), net. Derivatives are recorded on the balance sheet at fair value. The estimated fair value of derivative financial instruments represents the amount required to enter into similar offsetting contracts with similar remaining maturities based on quoted market prices. See Note 19 for further information concerning derivatives.

Fair-Value Measurements

We measure fair value using the framework established by the Financial Accounting Standards Board ("FASB") for fair value measurements and disclosures. This framework requires fair value to be determined based on the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants.

The valuation techniques are based upon observable and unobservable inputs. Observable or market inputs reflect market data obtained from independent sources. Unobservable inputs require management to make certain assumptions and judgments based on the best information available. Observable inputs are the preferred data source. These two types of inputs result in the following fair value hierarchy:



Level 1:	Quoted prices (unadjusted) for identical instruments in active markets.

Level 2:	Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3:	Prices or valuations that require management inputs that are both significant to the fair value measurement and unobservable.

Recent Accounting Pronouncements

In May 2014, the FASB issued ASU 2014-09, "Revenue from Contracts with Customers", which will supersede most existing U.S. GAAP revenue recognition guidance. This new standard requires an entity to recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration to which an entity expects to be entitled in exchange for those goods or services. In addition, ASU 2014-09 contains expanded disclosure requirements relating to the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. ASU 2014-09 is effective for fiscal periods beginning after December 15, 2016 and permits the use of either the full retrospective or cumulative effect transition method. Early adoption is not permitted. We have not yet selected a transition method and are evaluating the impact that this new standard will have on our consolidated financial statements.

Debt Disclosure [Abstract]
Line of Credit	Line of Credit On October 9, 2014, we extended the term of our Amended and Restated Credit Agreement ("Amended Credit Agreement") with U.S. Bank National Association ("U.S. Bank") to November 1, 2017. The Amended Credit Agreement provides for a $55.0 million line of credit ("Credit Line") that may be used for working capital and other general corporate purposes including acquisitions, share repurchases and capital expenditures. Amounts available for borrowing under the Credit Line are reduced by the balance of any outstanding letters of credit, of which there were $13 thousand at December 31, 2014. All obligations under the Credit Line are secured by substantially all of our U.S. personal property and tangible and intangible assets as well as 65% of our ownership interest in Enson Assets Limited, our wholly-owned subsidiary which controls our manufacturing factories in the PRC. Under the Amended Credit Agreement, we may elect to pay interest on the Credit Line based on LIBOR plus an applicable margin (varying from 1.25% to 1.75%) or base rate (based on the prime rate of U.S. Bank or as otherwise specified in the Amended Credit Agreement) plus an applicable margin (varying from 0.00% to 0.50% ). The applicable margins are calculated quarterly and vary based on our cash flow leverage ratio as set forth in the Amended Credit Agreement. There are no commitment fees or unused line fees under the Amended Credit Agreement. The Amended Credit Agreement includes financial covenants requiring a minimum fixed charge coverage ratio and a maximum cash flow leverage ratio. In addition, the Amended Credit Agreement also contains other customary affirmative and negative covenants and events of default. As of December 31, 2014, we were in compliance with the covenants and conditions of the Amended Credit Agreement. We had no interest expense on borrowings during the year ended December 31, 2014. Our total interest expense on borrowings was $23 thousand and $0.2 million during the years ended December 31, 2013 and 2012, respectively.

At December 31, 2014, we had federal and state Research and Experimentation ("R&E") income tax credit carryforwards of approximately $1.8 million and $7.3 million, respectively. The federal R&E credits begin to expire in 2032. The state R&E income tax credits do not have an expiration date.

At December 31, 2014, we had federal, state and foreign net operating losses of approximately $2.4 million, $6.0 million and $0.1 million, respectively. Included in the Company's U.S. net operating loss deferred tax assets above is approximately $7.9 million of unrealized gross deferred tax assets attributable to excess tax benefits associated with stock-based compensation that will impact stockholders' equity if and when such excess benefits are ultimately realized. Of the federal and state net operating losses above, $2.3 million and $3.8 million, respectively, were acquired as part of our 2004 acquisition of SimpleDevices. The federal, state, and foreign net operating loss carryforwards begin to expire during 2024, 2018, and 2022, respectively.

Internal Revenue Code Section 382 places certain limitations on the annual amount of net operating loss carryforwards that may be utilized if certain changes to a company’s ownership occur. Our 2004 acquisition of SimpleDevices was a change in ownership pursuant to Section 382 of the Internal Revenue Code, and the federal and state net operating loss carryforwards of SimpleDevices are limited but considered realizable in future periods. The annual federal limitation is approximately $0.6 million for 2014 and thereafter.

At December 31, 2014, we assessed the realizability of our deferred tax assets by considering whether it is "more likely than not" some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. We considered taxable income in carry-back years, the scheduled reversal of deferred tax liabilities, tax planning strategies and projected future taxable income in making this assessment. Due to uncertainties surrounding the realization of some of the Company’s deferred tax assets, primarily including state R&E income tax credits generated during the prior years and current year, the Company established a valuation allowance against its deferred tax assets. When recognized, the tax benefits relating to any reversal of this valuation allowance will be recorded as a reduction of income tax expense. Accordingly, a valuation allowance of $3.9 million was recorded as of December 31, 2012 related to the state R&E deferred tax asset. The total valuation allowance increased by $0.9 million and $0.8 million as of December 31, 2014 and 2013, respectively.

During the year ended December 31, 2013 we recognized an increase to paid-in capital and a decrease to income taxes payable of $0.9 million, related to the tax benefit from the exercise of non-qualified stock options and vesting of restricted stock under our stock-based incentive plans. During the year ended December 31, 2012 we recognized a decrease to paid-in capital and an increase to income taxes payable of $0.1 million, related to the tax benefit from the exercise of non-qualified stock options and vesting of restricted stock under our stock-based incentive plans.

The undistributed earnings of our foreign subsidiaries are considered to be indefinitely reinvested. Accordingly, no provision for U.S. federal and state income taxes or foreign withholding taxes has been provided on such undistributed earnings. Determination of the potential amount of unrecognized deferred U.S. income tax liability and foreign withholding taxes is not practicable because of the complexities associated with its hypothetical calculation; however, unrecognized foreign tax credits would be available to reduce some portion of the U.S. liability.

During 2012, China's State Administration of Taxation issued Circular 15 which required us to reevaluate our foreign deferred tax assets relating to our Chinese subsidiaries. These subsidiaries have recorded a deferred tax asset for social insurance and housing funds with the intent of being able to deduct these expenses once such liabilities have been settled. Circular 15 stipulates that payments into the aforementioned funds must be made within five years of recording the initial accrual or the tax deduction for these expenses will be forfeited. At December 31, 2014, we evaluated fund payments made prior to the preceding five years and determined that $0.7 million of our foreign deferred tax assets would not provide a future tax benefit due to the change in Chinese law. In adhering to the new law, we recorded increases to income tax expense of $0.7 million, $0.2 million and $0.6 million for the years ended December 31, 2014, 2013 and 2012, respectively, relating to decreases in the deferred tax assets of our Chinese subsidiaries.

Uncertain Tax Positions

At December 31, 2014 and 2013, we had unrecognized tax benefits of approximately $3.6 million and $3.6 million, including interest and penalties, respectively. In accordance with accounting guidance, we have elected to classify interest and penalties as components of tax expense. Interest and penalties were $0.2 million, $0.1 million, and $0.1 million for the years ended December 31, 2014, 2013 and 2012, respectively. Interest and penalties are included in the unrecognized tax benefits.

Our gross unrecognized tax benefits at December 31, 2014, 2013 and 2012, and the changes during those years then ended, were as follows:



(In thousands)	2014			2013			2012
Beginning balance	$	3,490		$	5,006		$	5,387

Ending balance	$	3,486		$	3,490		$	5,006

Approximately $3.2 million, $3.2 million and $4.7 million of the total amount of gross unrecognized tax benefits at December 31, 2014, 2013 and 2012, respectively, would affect the annual effective tax rate, if recognized. We are unaware of any positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly change within the next twelve months. We anticipate a decrease in gross unrecognized tax benefits of approximately $0.5 million within the next twelve months based on federal, state, and foreign statute expirations in various jurisdictions. We have classified uncertain tax positions as non-current income tax liabilities unless expected to be paid within one year.

We file income tax returns in the U.S. federal jurisdiction and in various state and foreign jurisdictions. At December 31, 2014, the open statutes of limitations for our significant tax jurisdictions are the following: federal are 2011 through 2013, state are 2010 through 2013 and foreign are 2008 through 2013.

Effective January 1, 2008, the Chinese Labor Contract Law was enacted in the PRC. This law mandated that PRC employers remit the applicable social insurance payments to their local government. Social insurance is comprised of various components such as pension, medical insurance, job injury insurance, unemployment insurance, and a housing assistance fund, and is administered in a manner similar to social security in the United States. This amount represents our estimate of the amounts due to the PRC government for social insurance on December 31, 2014 and 2013.

⁽²⁾

Accrued bonus includes an accrual for an extra month of salary ("13^th month salary") to be paid to employees in certain geographies where it is the customary business practice. This 13^th month salary is paid to these employees if they remain employed with us through December 31st. The total accrued for the 13^th month salary was $0.6 million and $0.6 million at December 31, 2014 and 2013, respectively.

Leases [Abstract]

Leases

We lease land, office and warehouse space, and certain office equipment under operating leases that expire at various dates through November 30, 2060.

Rent expense for our operating leases was $3.7 million, $3.5 million and $3.7 million for the years ended December 31, 2014, 2013 and 2012, respectively.

Estimated future minimum non-cancelable operating lease payments at December 31, 2014 were as follows:



(In thousands)	Amount
2015	$	3,035
2016	2,585
2017	2,179
2018	1,662
2019	886
Thereafter	2,591
Total operating lease commitments	$	12,938

Non-level Rents and Lease Incentives

Some of our leases are subject to rent escalations. For these leases, we recognize rent expense for the total contractual obligation utilizing the straight-line method over the lease term, ranging from 48 months to 125 months. The related short term liability is recorded in other accrued expenses (see Note 11) and the related long term liability is recorded in other long term liabilities. The total liability related to rent escalations was $1.1 million and $1.0 million at December 31, 2014 and 2013, respectively.

The lease agreement for our corporate headquarters contains an allowance for moving expenses and tenant improvements of $1.5 million. These moving and tenant improvement allowances are recorded within other accrued expenses and other long term liabilities, depending on the short term or long term nature, and are being amortized as a reduction of rent expense over the 125-month term of the lease, which began on May 15, 2012.

Rental Costs During Construction

Rental costs associated with operating leases incurred during a construction period are expensed.

Prepaid Leases

We operate two factories within the PRC on which the land is leased from the government as of December 31, 2014. These land leases were prepaid to the PRC government at the time our subsidiary occupied the land. We have obtained land-use right certificates for the land pertaining to these factories.

The first factory is located in the city of Guangzhou in the Guangdong province. The remaining net book value of this prepaid lease was $1.4 million on December 31, 2014, and will be amortized on a straight-line basis over approximately 15 years. The buildings located on this land had a net book value of $13.4 million on December 31, 2014 and will be depreciated over a remaining weighted average period of 17 years.

The second factory is located in the city of Yangzhou in the Jiangsu province. The remaining net book value of this prepaid lease was $2.8 million on December 31, 2014, and will be amortized on a straight-line basis over the remaining term of approximately 44 years. The buildings located on this land had a net book value of $23.6 million on December 31, 2014 and will be depreciated over a remaining weighted average period of 25 years.

Commitments and Contingencies

Indemnifications

We indemnify our directors and officers to the maximum extent permitted under the laws of the state of Delaware and we have entered into indemnification agreements with each of our directors and executive officers. In addition, we insure our individual directors and officers against certain claims and attorney’s fees and related expenses incurred in connection with the defense of such claims. The amounts and types of coverage may vary from period to period as dictated by market conditions. Management is not aware of any matters that require indemnification of its officers or directors.

Fair Price Provisions and Other Anti-Takeover Measures

Our Restated Certificate of Incorporation, as amended, contains certain provisions restricting business combinations with interested stockholders under certain circumstances and imposing higher voting requirements for the approval of certain transactions ("fair price" provisions). Any of these provisions may delay or prevent a change in control.

The "fair price" provisions require that holders of at least two-thirds of our outstanding shares of voting stock approve certain business combinations and significant transactions with interested stockholders.

Litigation

On March 2, 2012, we filed a lawsuit against Universal Remote Control, Inc. ("URC") in the United States District Court, Central District of California (Universal Electronics Inc. v. Universal Remote Control, Inc., SACV12-0039 AG (JPRx)) alleging that URC was infringing, directly and indirectly, four of our patents related to remote control technology. We alleged that this complaint related to multiple URC remote control products, including the URC model numbers UR5U-9000L, WR7 and other remote controls with different model names or numbers, but with substantially the same designs, features, and functionalities. We sought monetary relief for the infringement, including enhanced damages due to the willfulness of URC's actions, injunctive relief to enjoin URC from further infringing, including contributory infringement and/or inducing infringement, and attorney's fees. URC denied infringing our patents and asserted a variety of counterclaims and affirmative defenses including invalidity and unenforceability of our patents, misuse of patents, and a breach of contract action stemming from the settlement by us of an earlier lawsuit against URC. On January 29, 2013, the Court held its "Markman" hearing and on February 1, 2013, the Court issued its ruling that four of the 24 claims we asserted against URC were invalid, effectively removing one of the four patents alleged by us to be infringed by URC from this litigation. In March 2014, the Court further narrowed the scope of this litigation granting URC’s motion for summary judgment with respect to certain issues that effectively removed two additional patents. In March 2014, the Court also granted our motion for summary judgment on certain of URC’s defenses and counterclaims, including URC’s counterclaim for breach of contract. A trial was held from May 6, 2014 through May 20, 2014, and the jury returned a verdict that URC did not infringe on our remaining patent, and found for URC on patent validity and several equitable defenses in the lawsuit, although the jury's verdict on the equitable defenses was advisory in nature. A hearing on motions pertaining to the jury's verdict was held on August 18, 2014. On December 16, 2014, the Court entered its findings of fact and conclusions of law on the equitable issues and determined that our assertion of URC’s infringement of one of the patents at issue was barred by laches, but not by equitable estoppel or patent misuse. Further, the Court determined that our right to seek relief was not barred by unclean hands and on January 27, 2015, final judgment was entered by the Court accepting the jury’s verdict pertaining to invalidity, non-infringement, marking, and the equitable defense of laches and ordered us to pay URC’s costs of litigation, exclusive of attorney's fees, estimated to be immaterial in amount. On January 22, 2015, URC filed a motion seeking to recover its attorney’s fees incurred in connection with its defense of this lawsuit. We are opposing this motion. A hearing is scheduled for March 9, 2015 on this motion and at the present time, we cannot determine the likely outcome of this motion nor can we estimate the amount URC may claim or ultimately what amount, if any, the Court may award, which could be significant. On February 26, 2015, URC filed its notice of appeal with respect to rulings against it pertaining to the issues of patent misuse, unclean hands, implied license and all adverse orders, decisions, and opinions rulings of the Court, which appeal we will vigorously defend against. Further, we are currently evaluating whether to appeal any of the issues decided by the Court.

On June 28, 2013, we filed a second lawsuit against URC, also in the United States District Court, Central District of California (Universal Electronics Inc. v. Universal Remote Control, Inc., SACV13-00987 JAK (SHx)). In this second lawsuit, we are alleging that URC is infringing, directly and indirectly, ten additional patents that we own related to remote control technology. As in the first lawsuit, in this second lawsuit we have alleged that this complaint relates to multiple URC remote control products. We are seeking monetary relief for infringement, including enhanced damages due to the willfulness of URC's actions, injunctive relief to enjoin URC from further infringing, including contributory infringement and/or inducing infringement, and attorney's fees. In mid-July 2013, URC filed a Notice of Related Cases seeking to join this lawsuit with the lawsuit we filed against URC on March 2, 2012 and we did not object to this Notice. Consequently, this lawsuit was transferred to the Judge and Magistrate hearing our first lawsuit filed against URC. In addition, URC answered this complaint with a denial of infringement, asserting affirmative defenses, and seeking a ruling that URC has not infringed our patents, that our patents are invalid and unenforceable, that the patents have been licensed to URC, and an award of attorneys’ fees and costs. In mid-November 2013, we filed a motion to add affiliated URC suppliers, Ohsung Electronics Co, Ltd, a South Korean entity, and Ohsung Electronics USA, Inc., a California entity, (collectively "Ohsung"), to the lawsuit. In February 2014, Ohsung answered and counterclaimed with a general denial of wrongdoing and asserted the standard affirmative defenses of non-infringement, invalidity and unenforceability of our patents and breach of contract action stemming from the settlement by us of an earlier lawsuit against URC. In March 2014, we answered by disputing Ohsung’s defenses and with a general denial of Ohsung’s breach of contract complaint. In late June and early July of 2014, URC and Ohsung requested inter partes review ("IPR") with the US Patent and Trademark Office ("Patent Office" or "USPTO") for each of the ten patents pending in the second URC lawsuit. We intend to vigorously defend each patent before the Patent Office. During December 2014 and January 2015, the Patent Office issued its decisions on URC’s petitions and accepted for review all claims at issue with respect to five of the patents, certain claims at issue with respect to two of the patents and denied in full the request to review the other three patents at issue.We are presently reviewing the Patent Office’s decisions to determine our next steps which could include appealing the Patent Office’s acceptance of some or all of the seven patents and/or defending the patents in front of the USPTO. While the Patent Office was considering the IPR requests, this second lawsuit was stayed by the Court. On March 2, 2015, the parties filed a Joint Stipulation agreeing that the stay continue while the Patent Office decides the IPRs, which decisions are not expected until January 2016.

On September 23, 2013, we filed a lawsuit against Peel Technologies, Inc. ("Peel") in the United States District Court, Central District of California (Universal Electronics Inc. v. Peel Technologies, Inc., SACV13-01484 GAF (RNBx)) alleging that Peel is infringing, directly and indirectly, five of our patents related to remote control technology. We have alleged that this complaint relates to software and hardware used in connection with remote control devices, including Peel’s software products called "TV App" (sometimes referred to as "Sense TV"), "WatchOn App" and "Peel Smart Remote App," and a product called "Peel Universal Remote" consisting of a Peel "Fruit" hardware device and a software component for use with the iOS operating system. We are seeking monetary relief for the infringement, including enhanced damages due to the willfulness of Peel’s actions, injunctive relief to enjoin Peel from further infringement, including contributory infringement and/or inducing infringement, and attorney’s fees. On November 14, 2013, Peel answered our complaint with a general denial that it is infringing our patents and has filed counter-claims, seeking declaratory judgments that our patents are not infringed and are invalid. They are also seeking attorney’s fees. In our reply to Peel’s counterclaims, which we filed on December 5, 2013, we asked the Court to deny and dismiss with prejudice Peel’s counterclaims and sought after relief. In April 2014, both parties were granted leave by the court to amend the pleadings in the case. We added four additional patents related to remote control technology, and Peel filed a counterclaim against us alleging we are infringing one patent related to remote control technology which they recently acquired. We answered Peel’s counterclaim with a general denial of infringement and added our affirmative defenses of non-infringement, invalidity and unenforceability. A "Markman" hearing was held August 13, 2014 and the Court issued a ruling on September 17, 2014 which we believe supports our current claims of infringement against Peel. On November 10, 2014, the parties entered into a confidential settlement agreement in which the parties agreed to dismiss their respective patent infringement claims against each other without prejudice. This settlement had no impact on our consolidated financial condition, results of operations or cash flows. As part of this agreement, Peel agreed to modify and update its products to avoid our allegations of infringement. We intend to review any updated versions of the Peel products to determine their compliance with our agreement, and will determine an appropriate course of action following such review which we anticipate will take place within the first quarter of 2015.

In March 2014, two of our subsidiaries, Gemstar Technology (China) Co. Ltd. and Gemstar Technology (Yangzhou) Co. Ltd., each filed arbitration requests in Hong Kong under the arbitration rules of the Hong Kong International Arbitration Centre (the "HKIAC") against Dongguan City Liwang Battery Co. Ltd. ("LiWang"). In these requests, our subsidiaries claimed that LiWang supplied defective batteries and sought damages incurred as a result. LiWang opposed jurisdiction under the HKIAC and, in turn, filed claims against Gemstar Technology (China) Co. Ltd. in the People’s Court of Panyu District, and against Gemstar Technology (Yangzhou) Co., Ltd. in the People’s Court of Bao Ying District, each alleging breach of contract and that jurisdiction should be in China. We opposed these claims and were awaiting a final ruling by the China Courts. On August 29, 2014, the parties entered into a confidential Settlement Agreement whereby the parties each agreed to withdraw and terminate with prejudice and settle all of their respective claims and actions against the other parties. The settlement of this matter did not have a material impact on our consolidated financial condition, results of operations or cash flows.

There are no other material pending legal proceedings to which we or any of our subsidiaries is a party or of which our respective property is the subject. However, as is typical in our industry and to the nature and kind of business in which we are engaged, from time to time, various claims, charges and litigation are asserted or commenced by third parties against us or by us against third parties arising from or related to product liability, infringement of patent or other intellectual property rights, breach of warranty, contractual relations, or employee relations. The amounts claimed may be substantial but may not bear any reasonable relationship to the merits of the claims or the extent of any real risk of court awards assessed against us or in our favor. However, no assurances can be made as to the outcome of any of these matters, nor can we estimate the range of potential losses to us. In our opinion, final judgments, if any, which might be rendered against us in potential or pending litigation would not have a material adverse effect on our financial condition, results of operations, or cash flows. Moreover, we believe that our products do not infringe any third parties' patents or other intellectual property rights.

We maintain directors' and officers' liability insurance which insures our individual directors and officers against certain claims, as well as attorney's fees and related expenses incurred in connection with the defense of such claims.

Defined Benefit Plan

Our subsidiary in India maintains a defined benefit pension plan ("India Plan") for local employees, which is consistent with local statutes and practices. The pension plan was adequately funded on December 31, 2014 based on its latest actuarial report. The India Plan has an independent external manager that advises us of the appropriate funding contribution requirements to which we comply. At December 31, 2014, approximately 39 percent of our India subsidiary employees had qualified for eligibility. An individual must be employed by our India subsidiary for a minimum of 5 years before becoming eligible. Upon the termination, resignation or retirement of an eligible employee, we are liable to pay the employee an amount equal to 15 days salary for each full year of service completed. The total amount of liability outstanding at December 31, 2014 and 2013 for the India Plan was not material. During the years ended December 31, 2014, 2013, and 2012, the net periodic benefit costs were also not material.

Business Segment and Foreign Operations

Reportable Segment

An operating segment, in part, is a component of an enterprise whose operating results are regularly reviewed by the chief operating decision maker to make decisions about resources to be allocated to the segment and assess its performance. Operating segments may be aggregated only to a limited extent. Our chief operating decision maker, the Chief Executive Officer, reviews financial information presented on a consolidated basis, accompanied by disaggregated information about revenues for purposes of making operating decisions and assessing financial performance. Accordingly, we only have a single operating and reportable segment.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]

Stock-Based Compensation

Stock-based compensation expense for each employee and director is presented in the same income statement caption as their cash compensation. Stock-based compensation expense by income statement caption and the related income tax benefit were as follows:

Income tax benefit	$	1,897	$	1,575	$	1,488

Stock Options

The assumptions we utilized in the Black-Scholes option pricing model and the resulting weighted average fair value of stock option grants were the following:



	Year Ended December 31,
	2014			2013			2012
Weighted average fair value of grants ⁽¹⁾	$	13.64		$	9.26		$	9.57
Risk-free interest rate	1.29		%	0.95		%	0.86		%
Expected volatility	44.84		%	53.39		%	55.22		%
Expected life in years	4.56			5.20			5.15


⁽¹⁾	The weighted average fair value of grants was calculated utilizing the stock options granted during each respective period.

Stock option activity was as follows:



	2014							2013							2012
	Number of Options (in 000's)		Weighted-Average Exercise Price		Weighted-Average Remaining Contractual Terms (in years)	Aggregate Intrinsic Value (in 000's)		Number of Options (in 000's)		Weighted-Average Exercise Price		Weighted-Average Remaining Contractual Terms (in years)	Aggregate Intrinsic Value (in 000's)		Number of Options (in 000's)		Weighted-Average Exercise Price		Weighted-Average Remaining Contractual Terms (in years)	Aggregate Intrinsic Value (in 000's)

⁽¹⁾

The aggregate intrinsic value represents the total pre-tax value (the difference between our closing stock price on the last trading day of 2014, 2013, and 2012 and the exercise price, multiplied by the number of in-the-money options) that would have been received by the option holders had they all exercised their options on December 31, 2014, 2013, and 2012. This amount will change based on the fair market value of our stock.

During the years ended December 31, 2014, 2013, and 2012, there were no modifications made to outstanding stock options.

Cash received from option exercises for the years ended December 31, 2014, 2013, and 2012 was $8.1 million, $12.4 million, and $2.2 million, respectively. The actual tax benefit realized from option exercises was $3.1 million, $2.3 million and $0.2 million for the years ended December 31, 2014, 2013, and 2012, respectively.

Significant option groups outstanding at December 31, 2014 and the related weighted average exercise price and life information were as follows:



	Options Outstanding				Options Exercisable
Range of Exercise Prices	Number Outstanding (in 000’s)	Weighted-Average Remaining Years of Contractual Life	Weighted-Average Exercise Price		Number Exercisable (in 000’s)	Weighted-Average Exercise Price
$16.64 to $17.60	9	0.39	$	17.43	9	$	17.43

	650	5.59	$	25.56	421	$	23.84

As of December 31, 2014, we expect to recognize $2.1 million of total unrecognized pre-tax stock-based compensation expense related to non-vested stock options over a remaining weighted-average life of 1.8 years.

On February 12, 2015, the Board of Directors granted certain executive employees 73,680 stock options in connection with the 2014 annual review cycle. The options were granted as part of long-term incentive compensation to assist us in meeting our performance and retention objectives and are subject to a three-year vesting period (33.33% on February 12, 2016 and 8.33% each quarter thereafter). The total grant date fair value of these awards was $1.8 million.

Restricted Stock

Non-vested restricted stock award activity was as follows:



	Shares Granted (in 000’s)		Weighted-Average Grant Date Fair Value

Non-vested at December 31, 2014	266		$	39.28

As of December 31, 2014, we expect to recognize $9.5 million of total unrecognized pre-tax stock-based compensation expense related to non-vested restricted stock awards over a weighted-average life of 2.3 years.

On February 12, 2015, the Board of Directors granted certain executive employees 27,845 restricted stock awards in connection with the 2014 annual review cycle. The awards were granted as part of long-term incentive compensation to assist us in meeting our performance and retention objectives and are subject to a three-year vesting period (33.33% on February 12, 2016 and 8.33% each quarter thereafter). The total grant date fair value of these awards was $1.8 million.

Stock Incentive Plans

Our active stock-based incentive plans include those adopted in 1998, 1999, 2002, 2003, 2006, 2010 and 2014 ("Stock Incentive Plans"). Under the Stock Incentive Plans, we may grant stock options, stock appreciation rights, restricted stock units, performance stock units, or any combination thereof for a period of ten years from the approval date of each respective plan, unless the plan is terminated by resolution of our Board of Directors. No stock appreciation rights or performance stock units have been awarded under our Stock Incentive Plans. Only directors and employees meeting certain employment qualifications are eligible to receive stock-based awards.

The grant price of stock option and restricted stock awards granted under our Stock Incentive Plans is the average of the high and low trades of our stock on the grant date. We prohibit the re-pricing or backdating of stock options. Our stock options become exercisable in various proportions over a three- or four-year time frame. Stock options have a maximum ten-year term. Restricted stock awards vest in various proportions over a one- to three-year time period.

Detailed information regarding our active Stock Incentive Plans was as follows at December 31, 2014:

Derivatives

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivatives

We periodically enter into foreign currency exchange contracts with terms normally lasting less than nine months to protect against the adverse effects that exchange-rate fluctuations may have on our foreign currency-denominated receivables, payables, cash flows and reported income. We are exposed to market risks from foreign currency exchange rates, which may adversely affect our operating results and financial position. Our foreign currency exposures are primarily concentrated in the Argentinian Peso, Brazilian Real, British Pound, Chinese Yuan Renminbi, Euro, Hong Kong Dollar, Indian Rupee, and Singapore Dollar. Derivative financial instruments are used to manage risk and are not used for trading or other speculative purposes. We do not use leveraged derivative financial instruments and these derivatives have not qualified for hedge accounting.

Gains and losses on derivatives are recorded in other income (expense), net. Derivatives are recorded on the balance sheet at fair value. The estimated fair values of our derivative financial instruments represent the amount required to enter into offsetting contracts with similar remaining maturities based on quoted market prices. We have determined that the fair value of our derivatives are derived from level 2 inputs in the fair value hierarchy. The following table sets forth the fair value of derivatives:



	December 31, 2014								December 31, 2013
	Fair Value Measurement Using						Total		Fair Value Measurement Using						Total
(In thousands)	(Level 1)		(Level 2)		(Level 3)		Balance		(Level 1)		(Level 2)		(Level 3)		Balance
Foreign currency exchange futures contracts	$	—	$	810	$	—	$	810	$	—	$	509	$	—	$	509

We held foreign currency exchange contracts which resulted in a net pre-tax loss of approximately $0.5 million, a net pre-tax gain of approximately $0.9 million, and a net pre-tax gain of $35 thousand for the years ended December 31, 2014, 2013, and 2012, respectively.

Details of foreign currency exchange contracts held were as follows:

See Notes 6 and 15 for further information concerning long-lived assets. See Note 7 for further information concerning intangible assets.

Capitalized Software Development Costs

Capitalized software development costs are amortized on a product-by-product basis. Amortization is recorded in cost of sales and is the greater of the amounts computed using:


a.	the net book value at the beginning of the period multiplied by the ratio that current gross revenues for a product bear to the total of current and anticipated future gross revenues for that product; or


b.	the straight-line method over the remaining estimated economic life of the product including the period being reported on.

The amortization of capitalized software development costs begins when the related product is available for general release to customers. The amortization period is generally two years.

Derivatives

Fair-Value Measurements



Level 1:	Quoted prices (unadjusted) for identical instruments in active markets.

Level 2:	Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3:	Prices or valuations that require management inputs that are both significant to the fair value measurement and unobservable.
