Accounting Policies [Abstract]
Description of Business and Summary of Significant Accounting Policies	Note 1. Description of Business and Summary of Significant Accounting Policies Description of Business. RealNetworks, Inc. and subsidiaries is a leading global provider of network-delivered digital media applications and services that make it easy to manage, play and share digital media. The Company also develops and markets software products and services that enable the creation, distribution and consumption of digital media, including audio and video. Inherent in our business are various risks and uncertainties, including a limited history of certain of our product and service offerings. RealNetworks' success will depend on the acceptance of our technology, products and services and the ability to generate related revenue. In this Annual Report on Form 10-K for the year ended December 31, 2017 (10-K), RealNetworks, Inc. and subsidiaries is referred to as “RealNetworks”, the “Company”, “we”, “us”, or “our”. Basis of Presentation. The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. Intercompany balances and transactions have been eliminated in consolidation. The consolidated financial statements reflect all adjustments that, in the opinion of management, are necessary for a fair presentation of the results of operations for the periods presented. Operating results for the year ended December 31, 2017 are not necessarily indicative of the results that may be expected for any subsequent periods. On December 31, 2017, our contract with LOEN Entertainment, Co, Ltd. (LOEN) for our music on demand services expired without renewal. Accordingly, we have reported the operating results of this business as discontinued operations for all periods presented. The assets and liabilities of the music on demand business at December 31, 2017 and 2016 have been reported as assets and liabilities of discontinued operations in the Consolidated Balance Sheet. Refer to Note 16 Discontinued Operations. Unless otherwise noted, discussion within these notes to the consolidated financial statements relates to continuing operations. Use of Estimates. The preparation of financial statements in conformity with accounting principles generally accepted in the U.S. (GAAP) requires management 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. Actual results could differ from those estimates. Cash and Cash Equivalents and Short-Term Investments We consider all short-term investments with a remaining contractual maturity at date of purchase of three months or less to be cash equivalents. Other short-term investments with remaining contractual maturities of five years or less are classified as short-term because the investments are marketable and highly liquid, and we have the ability to utilize them for current operations. Realized gains and losses and any declines in value judged to be other-than-temporary on short-term investments are included in other income (expense), net. Realized and unrealized gains and losses on short-term investments are determined using the specific identification method. Trade Accounts Receivable. Trade accounts receivable consist of amounts due from customers and do not bear interest. The allowance for doubtful accounts and sales returns is our estimate of the amount of probable credit losses and returns in our existing accounts receivable. We determine the allowances based on analysis of historical bad debts, customer concentrations, customer credit-worthiness, return history and current economic trends. We review the allowances for doubtful accounts and sales returns quarterly. Past due balances over 90 days and specified other balances are reviewed individually for collectability. All other balances are reviewed on an aggregate basis. Account balances are written off against the allowance after all reasonable means of collection have been exhausted and the potential for recovery is considered remote. We do not have any off-balance sheet credit exposure related to our customers. Concentration of Credit Risk. Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash and cash equivalents, short-term investments, and accounts receivable. Short-term investments consist of U.S. government and government agency securities, corporate notes and bonds, and municipal securities. We derive a portion of our revenue from a large number of individual consumers spread globally. We also derive revenue from several large customers. If the financial condition or results of operations of any one of the large customers deteriorates substantially, our operating results could be adversely affected. To reduce credit risk, management performs ongoing credit evaluations of the financial condition of significant customers. We do not generally require collateral and we maintain an allowance for estimated credit losses on customer accounts when considered necessary. Depreciation and Amortization. Depreciation of equipment and software, as well as amortization of leasehold improvements is computed using the straight-line method over the lesser of the estimated useful lives of the assets or the related lease term. The useful life of equipment and software is generally three to five years. Depreciation and amortization expense of these assets during the years ended December 31, 2017 , 2016 , and 2015 was $2.3 million , $6.0 million and $8.1 million , respectively. Equity Method Investment. We use the equity method in circumstances where we have the ability to exert significant influence, but not control, over an investee or joint venture. We initially record our investment based on a fair value analysis of the investment. We record our percentage interest in the investee's recorded income or loss and changes in the investee's capital under this method, which will increase or decrease the reported value of our investment. See Note 4, Napster Joint Venture for additional information. We evaluate impairment of an investment accounted for under the equity method if events and circumstances warrant. An impairment charge would be recorded if a decline in the fair value of an equity investment below its carrying amount were determined to be other than temporary. In determining if a decline is other than temporary, we consider factors such as the length of time and extent to which the fair value of the investment has been less than the carrying amount of the investee or joint venture, the near-term and longer-term operating and financial prospects of the investee or joint venture and our intent and ability to hold the investment for a period of time sufficient to allow for any anticipated recovery. Deferred Costs. We defer certain costs on projects for service revenues and system sales. Deferred costs consist primarily of direct and incremental costs to customize and install systems, as defined in individual customer contracts, including costs to acquire hardware and software from third parties and payroll and related costs for employees and other third parties. Deferred costs are capitalized during the implementation period. We recognize such costs as a component of cost of revenue, the timing of which is dependent upon the revenue recognition policy by contract. At each balance sheet date, we review deferred costs to ensure they are ultimately recoverable. Any anticipated losses on uncompleted contracts are recognized when evidence indicates the estimated total cost of a contract exceeds its estimated total revenue or if actual deferred costs exceed estimated contractual revenue. Assessing the recoverability of deferred costs is based on significant assumptions and estimates, including future revenue and cost of sales. Significant or sustained decreases in revenue or increases in cost of sales in future periods could result in impairments of deferred project costs and prepaid royalty advances. We cannot accurately predict the amount and timing of any such impairments. Should deferred project costs or prepaid royalty advances become impaired, we would record the appropriate charge, which could have a material adverse effect on our financial condition and results of operations. Definite-Lived Tangible and Intangible Assets. Definite-lived tangible assets include equipment, software and leasehold improvements and are carried at cost less accumulated depreciation and amortization. Definite-lived intangible assets consist primarily of the fair value of customer agreements and contracts, and developed technology acquired in business combinations and are amortized over their estimated useful lives. We review these assets for impairment whenever events or changes in circumstances indicate the carrying amount of such assets may not be recoverable. If the carrying amount of an asset group is not recoverable, an impairment loss is recognized if the carrying amount of the asset group exceeds its estimated fair value, which is generally determined as the present value of estimated future cash flows to a market participant. Our impairment analysis is based on significant assumptions of future results, including operating and cash flow projections. Significant or sustained declines in future revenue or cash flows, or adverse changes in our business climate, among other factors, could result in the need to record an impairment charge in future periods. Goodwill. We test goodwill for impairment on an annual basis, in our fourth quarter, or more frequently if circumstances indicate reporting unit carrying values may exceed their fair values. Circumstances that may indicate a reporting unit's carrying value exceeds its fair value include, but are not limited to: poor economic performance relative to historical or projected future operating results; significant negative industry, economic or company specific trends; changes in the manner of our use of the assets or the plans for our business; and loss of key personnel. When evaluating goodwill for impairment, based upon our annual test or due to changes in circumstances described above, we first perform a qualitative assessment to determine if the fair value of a reporting unit is more likely than not less than the reporting unit's carrying amount including goodwill. If this assessment indicates it is more likely than not, we then compare the carrying value of the reporting unit to the estimated fair value of the reporting unit. If the carrying value of the reporting unit exceeds the estimated fair value, we then calculate the implied estimated fair value of goodwill for the reporting unit and compare it to the carrying amount of goodwill for the reporting unit. If the carrying amount of goodwill exceeds the implied estimated fair value, an impairment charge to current operations is recorded to reduce the carrying value to implied estimated value. Significant judgment is required in determining the reporting units and assessing fair value of the reporting units. Fair Value. Fair value is the price that would be received from selling an asset or paid in transfering a liability in an orderly transaction between market participants at the measurement date. Our fair value measurements consider the principal or most advantageous market in which we would transact and the market-based risk measurements or assumptions that market participants would use in pricing the asset or liability, such as inherent risk, transfer restrictions and credit risk. Fair values are determined based on three levels of inputs: • Level 1: Quoted prices in active markets for identical assets or liabilities • Level 2: Directly or indirectly observed inputs for the asset or liability, including quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active • Level 3: Significant unobservable inputs that reflect our own estimates of assumptions that market participants would use Research and Development. Costs incurred in research and development are expensed as incurred. Software development costs are capitalized when a product’s technological feasibility has been established through the date the product is available for general release to customers. Other than internal use software, we have not capitalized any software development costs, as technological feasibility is generally not established until a working model is completed, at which time substantially all development is complete. Revenue Recognition. We recognize revenue when persuasive evidence of an arrangement exists, delivery has occurred, the sales price is fixed or determinable, and collection is probable. Physical products are considered delivered to the customer once they have been shipped and title and risk of loss have been transferred. For online sales, the products or services are considered delivered at the time the products or services are made available, digitally, to the end user. We recognize revenue on a gross or net basis. In most arrangements, we contract directly with end user customers, and are the primary obligor. In such arrangements, we recognize revenue on a gross basis. In some cases, we utilize third-party distributors who are the primary obligor to sell products or services directly to end user customers. In such instances, we recognize revenue on a net basis. In our direct to consumer operations, we derive revenue through (1) subscriptions sold by our Games segment and subscriptions of SuperPass within our Consumer Media segment, (2) sales of content downloads, software and licenses offered by our Consumer Media, Mobile Services, and Games segments and (3) the sale of advertising and the distribution of third-party products on our websites and in our games. Consumer subscription products are paid in advance, typically for monthly, quarterly or annual duration. Subscription revenue is recognized ratably over the related subscription time period. Revenue from sales of content downloads, software and licenses is recognized at the time the product is made available, digitally, to the end user. Revenue generated from advertising on our websites and from advertising and the distribution of third-party products included in our products is recognized as revenue at the time of delivery. We also generate revenue through business-to-business channels by providing services within our Mobile Services segment enabling mobile carriers to deliver audio and video content to their customers and by selling software licenses and products and related support and other services. Revenue generated from services provided to mobile carriers that enable the delivery of audio and video content to their customers is recognized as the services are provided. Setup fees to build these services are recognized ratably upon launch of the service over the remaining expected term of the service. Non-software revenue arrangements containing multiple elements are divided into separate units of accounting, after being evaluated for specific criteria. If the criteria for separation are met, revenue is allocated to the individual units using the relative fair value method. If the criteria are not met, the elements are treated as one unit of accounting and revenue recognition is delayed until all elements have been delivered. In the case of revenue arrangements containing software, elements are divided into separate units of accounting only when vendor-specific objective evidence has been established. In cases where vendor-specific objective evidence has not been established, undelivered elements are combined into one unit of accounting and are not recognized in revenue until all elements have been delivered. Advertising Expenses. We expense the cost of advertising and promoting our products as incurred. These costs are included in sales and marketing expense and totaled $4.5 million in 2017 , $6.1 million in 2016 and $16.5 million in 2015 . Foreign Currency. The functional currency of the Company’s foreign subsidiaries is generally the currency of the country in which the subsidiary operates. Assets and liabilities of foreign operations are translated into U.S. dollars using rates of exchange in effect at the end of the reporting period. The net gain or loss resulting from translation is shown as translation adjustment and included in Accumulated Other Comprehensive Income (AOCI) in shareholders’ equity. Income and expense accounts are translated into U.S. dollars using average rates of exchange. Gains and losses from foreign currency transactions are included in the consolidated statements of operations. Accounting for Taxes Collected from Customers. Our revenues are reported net of sales and other transaction taxes that are collected from customers and remitted to taxing authorities. Income Taxes. We compute income taxes using the asset and liability method, under which deferred income taxes are provided for temporary differences between financial reporting basis and tax basis of our assets and liabilities and operating loss and tax credit carryforwards. We record a valuation allowance when it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of the deferred tax assets depends on the ability to generate sufficient taxable income of the appropriate character in the appropriate taxing jurisdictions. Adjustments to the valuation allowance could be required in the future if we estimate that the amount of deferred tax assets to be realized is more or less than the net amount we have recorded. Any increase or decrease in the valuation allowance could have the effect of increasing or decreasing the income tax provision in the statement of operations. Deferred tax assets and liabilities and operating loss and tax credit carryforwards are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences and operating loss and tax credit carryforwards are expected to be recovered or settled. We file numerous consolidated and separate income tax returns in the U.S. including federal, state and local, as well as foreign jurisdictions. With few exceptions, we are no longer subject to U.S. federal income tax examinations for tax years before 2013 or state, local, or foreign income tax examinations for years before 1993. We are currently under audit by various states and foreign jurisdictions for certain tax years subsequent to 1993. We recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. We recognize accrued interest and penalties related to uncertain tax positions as a component of income tax expense. Stock-Based Compensation. Stock-based compensation cost is measured at the grant date based on the fair value of the award and is recognized as expense over the requisite service period, which is the vesting period. We use the Black-Scholes option-pricing model or other appropriate valuation models such as Monte Carlo simulation to determine the fair value of stock-based option awards. The fair value of restricted stock awards is based on the closing market price of our common stock on the grant date of the award. Generally, we recognize the compensation cost for awards on a straight-line basis for the entire award, over the applicable vesting period. For performance-based awards, expense is recognized when it is probable the performance goal will be achieved, however if the likelihood becomes improbable, that expense is reversed. For market-based stock options, fair value is measured at the grant date using the Monte Carlo simulation model and we recognize compensation cost for these awards on a straight-line basis over the requisite service period for each separately vesting portion of the awards. For our employee stock purchase plan, compensation expense is measured based on the discount the employee is entitled to upon purchase. The valuation models for stock-based option awards require various judgmental assumptions including volatility in our common stock price and expected option life. If any of the assumptions used in the valuation models change significantly, stock-based compensation expense for new awards may differ materially in the future from the amounts recorded in the consolidated statements of operations. For all awards, we also estimate forfeitures at the time of grant and revise those estimates in subsequent periods if actual forfeitures differ from those estimates. Net Income Per Share. Basic net income (loss) per share (EPS) is computed by dividing net income (loss) by the weighted average number of common shares outstanding during the period. Diluted EPS is computed by dividing net income (loss) by the weighted average number of common and dilutive potential common shares outstanding during the period.

Accounting Changes and Error Corrections [Abstract]
Recent Accounting Pronouncements	Note 2. Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (FASB) issued new revenue recognition guidance, which was subsequently updated and amended in 2015 and 2016. The guidance requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The new guidance will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. The guidance permits two methods of adoption: the full retrospective method where the standard would be applied to each prior reporting period presented and the cumulative effect of applying the standard would be recognized at the earliest period shown, or the modified retrospective method, where the cumulative effect of applying the standard would be recognized at the date of initial application. We will adopt the requirements of the new standard effective January 1, 2018, and will use the modified retrospective transition method with the cumulative effect to the opening balance of retained earnings recognized as of the date of initial adoption. Under the new standard, the greatest impact will be in certain areas where we will be required to estimate usage which drives the underlying revenue. Under the current guidance, we do not recognize revenues until we achieve fixed and determinable status, which would typically be at a later date. We also expect an impact related to the licensing of our RealTimes and RealPlayer products. As we transition to the new revenue standard, we will recognize the revenue predominantly at the time of delivery rather than over the contract period, which results in an acceleration of revenue. Revenue recognition for all other product lines will not be be significantly impacted. The new standard will not have a cash impact and will not affect the economics of the underlying customer contracts. Our disclosures in our notes to the Consolidated Financial Statements related to revenue recognition will be significantly expanded under the new standard, specifically around the quantitative and qualitative information about our underlying performance obligations. Our assessment of impacts resulting from the new standard is substantially complete, including the impact on our controls and differences in the timing or method of revenue recognition for our contracts. As a result of our evaluation, we have modified certain accounting policies and practices and updated certain existing controls. We also designed and implemented specific controls over our evaluation of the impact of the new standard, including our calculation of the cumulative adjustment to Retained Deficit. As a result of the new standard, based on currently executed contracts, we expect to record a cumulative adjustment increasing our Retained Deficit on January 1, 2018 of approximately $1.0 million to $1.5 million . In February 2016, the FASB issued new guidance related to the accounting for leases by lessees. A major change in the new guidance is that lessees will be required to present right-of-use assets and lease liabilities on the balance sheet. The new guidance will be effective for us on January 1, 2019, including interim periods within 2019. We will continue to evaluate the effect that the guidance will have on our consolidated financial statements and related disclosures. We expect that the guidance will result in a material change to our Consolidated Balance Sheet as a result of capitalizing certain of our operating leases. In November 2016, the FASB issued new guidance on the classification and presentation of changes in restricted cash on the statement of cash flows. This guidance is effective for interim and annual reporting for us on January 1, 2018. We do not expect the adoption of this guidance to have a material qualitative impact on our statement of cash flows. In January 2017, the FASB issued new guidance simplifying the test for goodwill impairment. The new guidance eliminates Step 2 from the goodwill impairment test, instead requiring an entity to recognize a goodwill impairment charge for the amount by which the reporting unit's carrying amount exceeds the reporting unit's fair value. This guidance is effective for interim and annual goodwill impairment tests beginning on December 15, 2019, with early adoption permitted. We will be evaluating the impact of the guidance, but do not currently expect the adoption to have a material impact on our consolidated financial statements and related disclosures. There have been no other recent accounting pronouncements or changes in accounting pronouncements to be implemented that are of significance or potential significance to RealNetworks.

Acquisitions and Disposals	Note 3. Acquisitions and Disposals As described in our 2016 10-K, on July 24, 2015, we entered into an agreement to sell the Slingo and social casino portion of our games business to Gaming Realms plc. Of the total transaction price of $18.0 million , $10.0 million was paid in cash at closing on August 10, 2015, $4.0 million was paid in cash in August 2016, and the remaining $4.0 million was paid in cash in December 2017, along with an additional $0.5 million payment related to an agreed-to extension of this final payment, which was originally due in August 2017. We recognized the gain related to both the 2016 and 2017 payments in Gain (loss) on investments, net, on the statement of operations in 2016 and 2017. We recorded in 2015 the related foreign currency gain of $0.5 million in Other income and expense and an income tax benefit of $1.6 million from the reversal of a Slingo deferred tax liability.

Rhapsody Joint Venture

Rhapsody Joint Venture	12 Months Ended

Equity Method Investments and Joint Ventures [Abstract]
Rhapsody Joint Venture	Note 4. Napster Joint Venture As of December 31, 2017 we owned approximately 42% of the issued and outstanding stock of Rhapsody International, Inc., doing business as Napster, and account for our investment using the equity method of accounting. Rhapsody America LLC was initially formed in 2007 as a joint venture between RealNetworks and MTV Networks, a division of Viacom International Inc. (MTVN), to own and operate a business-to-consumer digital audio music service originally branded as Rhapsody. The service was re-branded in 2016 as Napster. In this Note, we refer to the business as Napster, although the legal entity in which we hold our investment is Rhapsody International, Inc. Following certain restructuring transactions effective March 31, 2010, we began accounting for our investment using the equity method of accounting. As part of the 2010 restructuring transactions, RealNetworks contributed $18.0 million in cash, the Rhapsody brand and certain other assets, including content licenses, in exchange for shares of convertible preferred stock of Rhapsody International, Inc., carrying a $10.0 million preference upon certain liquidation events. We recorded our share of losses of the Napster business of $4.0 million , $6.5 million , and $14.5 million for the years ended December 31, 2017 , 2016 and 2015 , respectively. Because of the $10.0 million liquidation preference on the preferred stock we hold in Napster, under the equity method of accounting we did not record any share of Napster losses that would reduce the carrying value of our investment, which is impacted by Napster equity transactions, below $10.0 million , until Napster's book value was reduced below $10.0 million , which occurred in the first quarter of 2015. As of December 31, 2017, the carrying value of our Napster equity investment was zero , as we did not have any further commitment to provide future support to Napster, with the exception of the guaranty discussed below. Unless we commit to provide future financial support to Napster, we do not record any further share of Napster losses that would reduce our carrying value of Napster below zero; in accordance with generally accepted accounting principles in the U.S., we currently track those suspended losses outside of our financial statements. In December 2016, RealNetworks entered into an agreement to loan up to $5 million to Napster for general operating purposes, as did Napster's other 42% owner, Columbus Nova. Each entity fully funded its loan, providing $3.5 million each in December 2016 and the remaining $1.5 million each in January 2017. These 12-month loans are subordinate to senior creditors, and bear an interest rate of 10% per annum, which accretes into the outstanding principal balance. At the time of signing the agreement we recognized previously suspended Napster losses, and, consequently, we did not record a receivable related to this loan. The parties have agreed to extend the term of these loans. During the second quarter of 2017, Napster defaulted on its loans to senior lenders due to a breach of a financial covenant, thus causing a cross default on Napster's loan to us. In June 2017, Napster obtained forbearance agreements from the senior lenders, pursuant to which (in general terms) the lenders agreed not to exercise remedies against Napster relating to defaults existing at June 30, 2017, which was subsequently extended through November 2017. In October 2017, Napster entered into a financing agreement with a new third party lender, pursuant to which Napster would factor certain receivables in return for cash advances. Napster applied the initial cash proceeds from this arrangement to pay in full and terminate all outstanding term loans with its then-existing third party lenders and a portion of amounts outstanding under a revolving credit facility. In November 2017, Napster entered into an amendment to its revolving credit facility, which updated all effective covenants and relieved all existing defaults, thereby relieving the cross default on Napster's loan to us and its loan to Columbus Nova. In conjunction with Napster's amendment to its revolving credit facility, both RealNetworks and Columbus Nova entered into an arrangement to guarantee up to $2.75 million each of Napster's outstanding indebtedness on the credit facility. As a result of this guaranty, we have recognized previously suspended Napster losses up to the full $2.75 million guaranty in the Equity in net loss of Napster investment line item in our consolidated statements of operations. As of the date of this filing, RealNetworks has not been required to pay any amounts under the guaranty, and the amount is reflected on our consolidated balance sheets as Commitment to Napster. Summarized financial information for Napster, which represents 100% of their financial information, is as follows (in thousands): Year ended December 31, Year ended December 31, Year ended December 31, Net revenue $ 172,391 $ 208,085 $ 201,987 Gross profit 27,173 38,407 32,761 Net loss (13,087 ) (14,913 ) (35,479 ) As of December 31, 2017 As of December 31, 2016 Current assets $ 43,028 $ 55,831 Non-current assets 16,874 18,273 Current liabilities 119,826 104,906 Non-current liabilities 1,231 20,238

Fair Value Measurements as of Amortized Cost as of December 31, 2017 December 31, 2017 Level 1 Level 2 Level 3 Total Cash and cash equivalents: Cash $ 31,065 $ — $ — $ 31,065 $ 31,065 Money market funds 20,131 — — 20,131 20,131 Total cash and cash equivalents 51,196 — — 51,196 51,196 Short-term investments: Corporate notes and bonds — 8,779 — 8,779 8,779 Total short-term investments — 8,779 — 8,779 8,779 Restricted cash equivalents and investments — 2,400 — 2,400 2,400 Warrants issued by Napster (included in Other assets) — — 989 989 — Total $ 51,196 $ 11,179 $ 989 $ 63,364 $ 62,375 Fair Value Measurements as of Amortized Cost as of December 31, 2016 December 31, 2016 Level 1 Level 2 Level 3 Total Cash and cash equivalents: Cash $ 32,585 $ — $ — $ 32,585 $ 32,585 Money market funds 136 — — 136 136 Corporate notes and bonds — 1,000 — 1,000 1,000 Total cash and cash equivalents 32,721 1,000 — 33,721 33,721 Short-term investments: Corporate notes and bonds — 43,331 — 43,331 43,343 Total short-term investments — 43,331 — 43,331 43,343 Restricted cash equivalents and investments — 2,700 — 2,700 2,700 Warrant issued by Napster (included in Other assets) — — 773 773 $ — Total $ 32,721 $ 47,031 $ 773 $ 80,525 $ 79,764 Restricted cash equivalents and investments as of December 31, 2017 and 2016 relate to cash pledged as collateral against letters of credit in connection with lease agreements. Realized gains and losses on sales of short-term investment securities for 2017 , 2016 , and 2015 were not significant. Gross unrealized gains and gross unrealized losses on short-term investment securities as of December 31, 2017 and 2016 were not significant. Investments with remaining contractual maturities of five years or less are classified as short-term because the investments are marketable and highly liquid, and we have the ability to utilize them for current operations. Contractual maturities of short-term investments as of December 31, 2017 are as follows (in thousands): Estimated Fair Value Within one year $ 8,419 Between one year and five years 360 Total short-term investments $ 8,779 In February 2015, Napster issued warrants to purchase Napster common shares to both RealNetworks and Columbus Nova. The warrants were issued as compensation for past services provided by RealNetworks and Columbus Nova, and both warrants covered the same number of underlying shares, with a 10 year contractual term. The exercise price of the warrants was equal to the fair value of the underlying shares on the issuance date, and we used the Black-Scholes option-pricing model to calculate the fair value of the warrant, using an expected term of 5 years and expected volatility of 55% . On the date of issuance, we recognized and recorded the $1.2 million fair value of the warrant issued to RealNetworks within Other assets in the consolidated balance sheets, and as an expense reduction within General and administrative expense in the consolidated statements of operations. The warrants are free-standing derivatives and as such their fair value is determined each quarter using updated inputs in the Black-Scholes option-pricing model. At December 31, 2017, due to the management change and strategic shift undertaken by Napster, we determined that a change to the expected term was necessary. As a result, we extended the expected term by 3.25 years , resulting in a total expected term for the warrant of 8.25 years . During the twelve months ended December 31, 2017 the decrease in the fair value of the warrants was approximately $0.1 million . In February 2017, Napster issued additional warrants to purchase Napster common shares to both RealNetworks and Columbus Nova. Consistent with the warrants issued in 2015, the 2017 warrants were issued as compensation for past services provided by RealNetworks and Columbus Nova, and both warrants covered the same number of underlying shares, with a 10 year contractual term. The exercise price of the warrants exceeded the fair value of the underlying shares on the issuance date, and we used the Black-Scholes option-pricing model to calculate the fair value of the warrant, using an expected term of 5 years and expected volatility of 55% , resulting in a recognized fair value of $0.5 million in Other assets in the consolidated balance sheets, and as an expense reduction within General and administrative expense in the consolidated statements of operations. At December 31, 2017, due to the management change and strategic shift undertaken by Napster, we determined that a change to the expected term was necessary. As a result, we extended the expected term by 1 year, resulting in a total expected term for the warrant of 6 years . During the twelve months ended December 31, 2017 the decrease in fair value of the warrants was approximately $0.2 million . Items Measured at Fair Value on a Non-recurring Basis Certain of our assets and liabilities are measured at estimated fair value on a non-recurring basis, using Level 3 inputs. These instruments are subject to fair value adjustments only in certain circumstances (for example, when there is evidence of impairment). We did not record any impairments on those assets required to be measured at fair value on a non-recurring basis in 2017 , 2016 or 2015 . See Note 11. Lease Exit and Related Charges , for a discussion of the losses related to reductions in the use of RealNetworks' office space, which were recorded at the estimated fair value of remaining lease obligations, less expected sub-lease income.

Lease Exit and Related Charges	Note 11. Lease Exit and Related Charges As a result of the reduction in use of RealNetworks' office space, primarily in our corporate headquarters in Seattle, Washington, and certain other locations, losses have been recognized representing rent and contractual operating expenses over the remaining life of the leases, including contractual, or estimates of, sublease income expected to be received, and related write-downs of leasehold improvements to their estimated fair value. In 2015, we recorded $2.5 million of losses primarily relating to an approximate 43% reduction of office space at our leased corporate headquarters in Seattle, Washington. In 2016, we recorded additional losses of $2.2 million primarily relating to reduction of our office space at our corporate headquarters, resulting in total reduction of 69% as of December 31, 2016. We continue to regularly evaluate the market for office space. If the market for such space changes further in future periods, we may have to revise our estimates which may result in future adjustments to expense for excess office facilities.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Employee Stock and Benefit Plans	Note 13. Employee Stock and Benefit Plans Equity Compensation Plans. Under our equity incentive plans we may grant various types of equity awards to employees and Directors. We have granted time-vest and performance-vest stock options and time-vest and performance-vest restricted stock. Generally, options vest based on continuous employment, over a four -year period. The options generally expire seven years from the date of grant and are exercisable at the market value of the common stock at the grant date. Time-vest restricted stock awards generally vest based on continuous employment over a two or four -year period. Performance-based awards vest if the specified performance targets are met and the grantee remains employed over the required period. The performance targets for these awards are generally based on the achievement of company-specific financial results. For these performance-based awards, expense is recognized when it is probable the performance goal will be achieved. We have also issued market-based performance stock options to certain employees. These awards vest if the market condition is met and the grantee remains employed over the requisite service period. We issue new shares of common stock upon exercise of stock options and the vesting of restricted stock. As of December 31, 2017 there were 5.9 million shares of common stock authorized for future equity awards. Each restricted stock unit granted reduces and each restricted stock unit forfeited or canceled increases the shares available for future grant by a factor of 1.6 shares. Each stock option granted reduces and each stock option forfeited or canceled increases the shares available for future grant by a factor of one share. We also have an employee stock purchase plan, under which 0.3 million shares of common stock are authorized for future issuance as of December 31, 2017 . Stock-based compensation expense recognized in our consolidated statements of operations includes amounts related to stock options, restricted stock, and employee stock purchase plans and was as follows (in thousands): Years Ended December 31, 2017 2016 2015 Total stock-based compensation expense $ 3,675 $ 5,424 $ 4,698 The total stock-based compensation amounts disclosed above are recorded in the respective line items within operating expenses in the consolidated statement of operations. Included in the expense for both 2017 and 2016 was stock compensation expense recorded for 2016 and 2015, respectively, incentive bonuses paid in fully vested restricted stock units which were authorized and granted in 2017 and 2016. No stock-based compensation was capitalized as part of the cost of an asset as of December 31, 2017 , 2016 , or 2015 . As of December 31, 2017 , we had $4.0 million of total unrecognized compensation cost, net of estimated forfeitures, related to stock awards. The unrecognized compensation cost is expected to be recognized over a weighted-average period of approximately two years. As discussed in Note 1. Description of Business and Summary of Significant Accounting Policies , the valuation models for stock option awards require various highly judgmental assumptions. The assumption for the expected term of the options represents the estimated period of time until exercise and is based on historical experience of similar awards, including the contractual terms, vesting schedules, and expectations of future employee behavior. Expected stock price volatility is based on historical volatility of our common stock for the related expected term. The risk-free interest rate is based on the implied yield available on U.S. Treasury zero-coupon issues with a term equivalent to the expected term of the stock options. The dividend yield is estimated at zero because we do not currently anticipate paying dividends in the foreseeable future. The fair value of options granted, excluding the options related to the 2016 Exchange described below, used the following weighted average assumptions: Years ended December 31, 2017 2016 2015 Expected dividend yield — % — % — % Risk-free interest rate 1.99 % 1.59 % 1.47 % Expected term (years) 5.3 5.1 4.8 Volatility 36 % 35 % 38 % Restricted stock unit and award activity was as follows (shares are in thousands): Shares Weighted Average Grant Date Fair Value Per Share Total Grant Date Fair Value of Vested Awards (000's) Nonvested shares, December 31, 2014 400 $ 7.47 Granted 296 5.44 Vested (109 ) 7.01 $ 763 Forfeited/Canceled (263 ) 7.27 Nonvested shares, December 31, 2015 324 $ 5.94 Granted 832 3.75 Vested (802 ) 3.83 $ 3,069 Forfeited/Canceled (22 ) 5.61 Nonvested shares, December 31, 2016 332 $ 5.59 Granted 230 4.66 Vested (347 ) 5.64 $ 1,957 Forfeited/Canceled (23 ) 4.38 Nonvested shares, December 31, 2017 192 $ 4.53 At December 31, 2017 the aggregate intrinsic value of restricted stock awards was $0.7 million and the weighted average remaining contractual term was approximately 1 year . Stock option activity (shares are in thousands): Options Outstanding Weighted Average Grant Date Fair Value Number of Shares Weighted Average Exercise Price Outstanding, December 31, 2014 6,724 $ 8.19 Options granted at common stock price 907 5.31 $ 1.70 Options exercised (14 ) 1.92 Options cancelled (2,100 ) 8.59 Outstanding, December 31, 2015 5,517 $ 7.58 Options granted at common stock price 1,230 4.50 $ 1.51 Options cancelled as part of stock option exchange (1,961 ) 8.11 Options granted as part of stock option exchange 1,961 4.73 $ 0.74 Options exercised (90 ) 3.69 Options cancelled (796 ) 8.81 Outstanding, December 31, 2016 5,861 $ 5.73 Options granted at common stock price 993 4.29 $ 1.51 Options exercised (21 ) 3.51 Options cancelled (757 ) 6.00 Outstanding, December 31, 2017 6,076 $ 5.47 Exercisable, December 31, 2017 3,709 $ 6.04 Vested and expected to vest, December 31, 2017 5,997 $ 5.49 In 2016 and 2015 we granted 400,000 and 200,000 market-based stock options, which are included in the stock option tables above. As of December 31, 2017 , the weighted average remaining contractual life of the options was as follows: outstanding options 4.9 years; exercisable options 4.1 years; and vested and expected to vest options 4.9 years. As of December 31, 2017 , there was no aggregate intrinsic value for our outstanding, exercisable or vested and expected to vest options. The aggregate intrinsic value of stock options exercised in 2017 , 2016 and 2015 was insignificant. Employee Stock Purchase Plan. Our Employee Stock Purchase Plan (ESPP) allows an eligible employee to purchase shares of our common stock at a price equal to 85 percent of the fair market value of the common stock at the end of the semi-annual offering periods, subject to certain limitations. Under the ESPP, 49,700 , 53,600 and 94,400 shares were purchased during the years ended December 31, 2017 , 2016 and 2015 , respectively. Retirement Savings Plan. We have a salary deferral plan (401(k) Plan) that covers substantially all employees. Eligible employees may contribute a portion of their eligible compensation to the plan up to limits stated in the plan documents, not to exceed the dollar amounts set by applicable laws. During the years ended December 31, 2017 , 2016 , and 2015 , we matched 50% of the first three percent of participating employees’ contributions, and contributed $0.3 million , $0.3 million , and $0.6 million , respectively, in matching contributions. We can terminate the matching contributions at our discretion. We have no other post-employment or post-retirement benefit plans. Stock Option Exchange. In September 2016, our shareholders approved amendments to our stock plans to allow for an option exchange program. The program, which launched on November 3, 2016, offered eligible employees and certain other service providers an opportunity to exchange certain outstanding options, with a per share exercise price in excess of $4.33 (the "Eligible Options"), for new awards. The Company granted these new options on December 6, 2016, with an exercise price of $4.73 , the fair market price of the Company's common stock as quoted on the Nasdaq Global Select Market at the close of business on that day. Members of the Company's Board of Directors, including our CEO, were not eligible for this program. In connection with the program, options to purchase 2.0 million shares of the Company's common stock were exchanged, representing 58% of total shares of common stock underlying the Eligible Options. As a result of the exchange, an additional $1.5 million , gross of estimated forfeitures, will be recognized over approximately 2 years , or the remaining average vesting period.

In 2017 , we continued to record a valuation allowance on the deferred tax assets that we believe are not more likely than not to be realized. The net change in valuation allowance was a $39.2 million decrease and a $2.4 million increase during the years ended December 31, 2017 and 2016 , respectively. We maintain a valuation allowance of $137.1 million for our deferred tax assets due to uncertainty regarding their realization as of December 31, 2017 . The net decrease in the valuation allowance since December 31, 2016 of $39.2 million was the result of a decrease in current year deferred tax assets, which was primarily related to the reduction in corporate tax rate as a result of the Tax Act, for which the Company maintains a valuation allowance. RealNetworks' U.S. federal net operating loss carryforwards totaled $283.1 million and $268.5 million at December 31, 2017 and 2016 , respectively. The increase is mainly due to the current year U.S. taxable loss. The remaining net operating loss carryforwards as of December 31, 2017 are from prior U.S. taxable losses and from acquired subsidiaries that are limited under Internal Revenue Code Section 382. These net operating loss carryforwards expire between 2024 and 2037. In 2017, we evaluated the current and future impacts of the Tax Act. The primary impact in 2017 was the elimination of the AMT credit carryforward. We have concluded on a preliminary basis, as allowed under the SEC's SAB 118, that we will not owe U.S. taxes on previously untaxed accumulated and current E&P of certain foreign subsidiaries or on global intangible low-taxed income earned by controlled foreign corporations. This preliminary conclusion is based on our history of negative E&P generated by our foreign subsidiaries. RealNetworks' AMT credit carryforward remained at $3.6 million from December 31, 2016 to December 31, 2017 . The Tax Act repealed the corporate AMT for tax years beginning January 1, 2018, and provides that existing AMT credit carryovers are refundable beginning in 2018. The Company's $3.6 million of AMT credit carryovers are expected to be fully refunded by 2022. A $3.6 million benefit has been recognized in the 2017 income tax provision as a result of this change in the U.S. tax law. RealNetworks' U.S. federal research and development tax credit carryforward totaled $24.5 million and $24.7 million at December 31, 2017 and 2016 , respectively. The research and development credit carryforwards expire between 2020 and 2036. As of December 31, 2017 and 2016 , we had $0.4 million and $0.5 million of unrecognized tax benefits, respectively. The decrease in unrecognized tax benefits is due to federal research and development tax credit carryforward risks. As of December 31, 2017, there are no unrecognized tax benefits remaining that would affect our effective tax rate if recognized, as the offset would increase the valuation allowance. We do not anticipate that the total amount of unrecognized tax benefits will significantly change within the next twelve months. We recognize interest and penalties related to unrecognized tax benefits within the provision for income taxes. As of December 31, 2017 , and 2016 we have no accrued interest or penalties related to uncertain tax positions. Reconciliation of the beginning and ending balances of the total amounts of unrecognized tax benefits (in thousands): Years ended December 31, 2017 2016 2015 Balance, beginning of year $ 493 $ 320 $ 3,541 Increases related to prior year tax positions — 38 — Decreases related to prior year tax positions (135 ) — (33 ) Settlements with taxing authorities — — (3,285 ) Increases related to current year tax positions — 135 97 Balance, end of year $ 358 $ 493 $ 320

Discontinued Operations	Note 16. Discontinued Operations On December 31, 2017, our contract with our low-margin music on demand customer LOEN expired. The activity for this contract represented our only revenue source relating to music on demand services, and we did not renew the sole contract for this service, resulting in the abandonment of the related business. As the exit of the music on demand business represents a strategic shift, and the amounts were financially significant to our consolidated results, at December 31, 2017 we determined this business should be reported as a discontinued operation. The following table summarizes the results of operations, which were recorded in our Mobile Services segment, relating to the discontinued operation (in thousands): 2017 2016 2015 Net revenue $ 46,034 $ 38,989 $ 32,848 Cost of revenue 44,612 37,420 30,777 Gross profit 1,422 1,569 2,071 Income taxes 313 346 456 Income from discontinued operations, net of tax $ 1,109 $ 1,223 $ 1,615 The following table summarizes the carrying amounts of major classes of assets and liabilities of the discontinued operation (in thousands): December 31, December 31, Trade accounts receivable, net $ 17,456 $ 14,206 Total current assets of discontinued operations 17,456 14,206 Accounts payable $ 15,836 $ 13,498 Accrued and other current liabilities 1,271 1,043 Total current liabilities of discontinued operations $ 17,107 $ 14,541 The cash flows related to the discontinued operation have not been segregated, and are included in the Consolidated Statements of Cash Flows.

Rent expense during the years ended December 31, 2017 , 2016 , and 2015 , was $3.0 million , $4.2 million , and $5.8 million , respectively. In late 2017 we entered into an arrangement whereby we may be required to guarantee up to $2.75 million of Napster's outstanding indebtedness on their revolving credit facility. As of the date of this filing, we have not been required to pay any portion of this commitment. For additional details, refer to Note 4. Napster Joint Venture. We could in the future become subject to legal proceedings, governmental investigations and claims in the ordinary course of business, including employment claims, contract-related claims, and claims of alleged infringement of third-party patents, trademarks and other intellectual property rights. Such claims, even if not meritorious, could force us to expend significant financial and managerial resources. In addition, given the broad distribution of some of our consumer products, any individual claim related to those products could give rise to liabilities that may be material to us. In the event of a determination adverse to us, we may incur substantial monetary liability, and/or be required to change our business practices. Either of these could have a material adverse effect on our consolidated financial statements.

Guarantees [Abstract]
Guarantees	Note 18. Guarantees In the ordinary course of business, RealNetworks is subject to potential obligations for standard warranty and indemnification provisions that are contained within many of our customer license and service agreements. Our warranty provisions are consistent with those prevalent in our industry, and we do not have a history of incurring losses on warranties; therefore, we do not maintain accruals for warranty-related obligations. With regard to indemnification provisions, nearly all of our carrier contracts obligate us to indemnify our carrier customers for certain liabilities that may be incurred by them. We have received in the past, and may receive in the future, claims for indemnification from some of our carrier customers. In relation to certain patents and other technology assets we sold to Intel in the second quarter of 2012, we have specific obligations to indemnify Intel for breaches of the representations and warranties that we made and covenants that we agreed to in the asset purchase agreement for certain potential future intellectual property infringement claims brought by third parties against Intel. The amount of any potential liabilities related to our indemnification obligations to Intel will not be determined until a claim has been made, but we are obligated to indemnify Intel up to the amount of the gross purchase price that we received in the sale.

Segment Reporting [Abstract]
Segment Information	Note 19. Segment Information We manage our business and report revenue and operating income (loss) in three segments: (1) Consumer Media, which includes licensing of our codec technology and our PC-based RealPlayer products, including RealPlayer Plus and related products; (2) Mobile Services, which includes our SaaS services and our integrated RealTimes ® platform which is sold to mobile carriers; and (3) Games, which includes all our games-related businesses, including sales of mobile games, sales of games licenses, online games subscription services, advertising on games sites and social network sites, and microtransactions from online and social games. We allocate to our reportable segments certain corporate expenses which are directly attributable to supporting the businesses, including but not limited to a portion of finance, legal, human resources and headquarters facilities. Remaining expenses, which are not directly attributable to supporting the business, are reported as corporate items. Also reported in our corporate segment are restructuring, lease exit and related charges, as well as stock compensation charges. RealNetworks reports the three reportable segments based on factors such as how we manage our operations and how our Chief Operating Decision Maker (CODM) reviews results. The CODM reviews financial information presented on both a consolidated basis and on a business segment basis.

Accounting Policies [Abstract]
Description of Business	Description of Business. RealNetworks, Inc. and subsidiaries is a leading global provider of network-delivered digital media applications and services that make it easy to manage, play and share digital media. The Company also develops and markets software products and services that enable the creation, distribution and consumption of digital media, including audio and video. Inherent in our business are various risks and uncertainties, including a limited history of certain of our product and service offerings. RealNetworks' success will depend on the acceptance of our technology, products and services and the ability to generate related revenue. In this Annual Report on Form 10-K for the year ended December 31, 2017 (10-K), RealNetworks, Inc. and subsidiaries is referred to as “RealNetworks”, the “Company”, “we”, “us”, or “our”.
Basis of Presentation	Basis of Presentation. The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. Intercompany balances and transactions have been eliminated in consolidation. The consolidated financial statements reflect all adjustments that, in the opinion of management, are necessary for a fair presentation of the results of operations for the periods presented. Operating results for the year ended December 31, 2017 are not necessarily indicative of the results that may be expected for any subsequent periods. On December 31, 2017, our contract with LOEN Entertainment, Co, Ltd. (LOEN) for our music on demand services expired without renewal. Accordingly, we have reported the operating results of this business as discontinued operations for all periods presented. The assets and liabilities of the music on demand business at December 31, 2017 and 2016 have been reported as assets and liabilities of discontinued operations in the Consolidated Balance Sheet. Refer to Note 16 Discontinued Operations. Unless otherwise noted, discussion within these notes to the consolidated financial statements relates to continuing operations.
Use of Estimates	Use of Estimates. The preparation of financial statements in conformity with accounting principles generally accepted in the U.S. (GAAP) requires management 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. Actual results could differ from those estimates.
Cash and, Cash Equivalents, and Short-Term Investments	Cash and Cash Equivalents and Short-Term Investments We consider all short-term investments with a remaining contractual maturity at date of purchase of three months or less to be cash equivalents. Other short-term investments with remaining contractual maturities of five years or less are classified as short-term because the investments are marketable and highly liquid, and we have the ability to utilize them for current operations. Realized gains and losses and any declines in value judged to be other-than-temporary on short-term investments are included in other income (expense), net. Realized and unrealized gains and losses on short-term investments are determined using the specific identification method.
Trade Accounts Receivable	Trade Accounts Receivable. Trade accounts receivable consist of amounts due from customers and do not bear interest. The allowance for doubtful accounts and sales returns is our estimate of the amount of probable credit losses and returns in our existing accounts receivable. We determine the allowances based on analysis of historical bad debts, customer concentrations, customer credit-worthiness, return history and current economic trends. We review the allowances for doubtful accounts and sales returns quarterly. Past due balances over 90 days and specified other balances are reviewed individually for collectability. All other balances are reviewed on an aggregate basis. Account balances are written off against the allowance after all reasonable means of collection have been exhausted and the potential for recovery is considered remote. We do not have any off-balance sheet credit exposure related to our customers.
Concentration of Credit Risk	Concentration of Credit Risk. Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash and cash equivalents, short-term investments, and accounts receivable. Short-term investments consist of U.S. government and government agency securities, corporate notes and bonds, and municipal securities. We derive a portion of our revenue from a large number of individual consumers spread globally. We also derive revenue from several large customers. If the financial condition or results of operations of any one of the large customers deteriorates substantially, our operating results could be adversely affected. To reduce credit risk, management performs ongoing credit evaluations of the financial condition of significant customers. We do not generally require collateral and we maintain an allowance for estimated credit losses on customer accounts when considered necessary.
Depreciation and Amortization	Depreciation and Amortization. Depreciation of equipment and software, as well as amortization of leasehold improvements is computed using the straight-line method over the lesser of the estimated useful lives of the assets or the related lease term. The useful life of equipment and software is generally three to five years.
Equity Method Investments	Equity Method Investment. We use the equity method in circumstances where we have the ability to exert significant influence, but not control, over an investee or joint venture. We initially record our investment based on a fair value analysis of the investment. We record our percentage interest in the investee's recorded income or loss and changes in the investee's capital under this method, which will increase or decrease the reported value of our investment. See Note 4, Napster Joint Venture for additional information. We evaluate impairment of an investment accounted for under the equity method if events and circumstances warrant. An impairment charge would be recorded if a decline in the fair value of an equity investment below its carrying amount were determined to be other than temporary. In determining if a decline is other than temporary, we consider factors such as the length of time and extent to which the fair value of the investment has been less than the carrying amount of the investee or joint venture, the near-term and longer-term operating and financial prospects of the investee or joint venture and our intent and ability to hold the investment for a period of time sufficient to allow for any anticipated recovery.
Deferred Costs	Deferred Costs. We defer certain costs on projects for service revenues and system sales. Deferred costs consist primarily of direct and incremental costs to customize and install systems, as defined in individual customer contracts, including costs to acquire hardware and software from third parties and payroll and related costs for employees and other third parties. Deferred costs are capitalized during the implementation period. We recognize such costs as a component of cost of revenue, the timing of which is dependent upon the revenue recognition policy by contract. At each balance sheet date, we review deferred costs to ensure they are ultimately recoverable. Any anticipated losses on uncompleted contracts are recognized when evidence indicates the estimated total cost of a contract exceeds its estimated total revenue or if actual deferred costs exceed estimated contractual revenue. Assessing the recoverability of deferred costs is based on significant assumptions and estimates, including future revenue and cost of sales. Significant or sustained decreases in revenue or increases in cost of sales in future periods could result in impairments of deferred project costs and prepaid royalty advances. We cannot accurately predict the amount and timing of any such impairments. Should deferred project costs or prepaid royalty advances become impaired, we would record the appropriate charge, which could have a material adverse effect on our financial condition and results of operations.
Other Definite-Lived Intangible Assets	Definite-Lived Tangible and Intangible Assets. Definite-lived tangible assets include equipment, software and leasehold improvements and are carried at cost less accumulated depreciation and amortization. Definite-lived intangible assets consist primarily of the fair value of customer agreements and contracts, and developed technology acquired in business combinations and are amortized over their estimated useful lives. We review these assets for impairment whenever events or changes in circumstances indicate the carrying amount of such assets may not be recoverable. If the carrying amount of an asset group is not recoverable, an impairment loss is recognized if the carrying amount of the asset group exceeds its estimated fair value, which is generally determined as the present value of estimated future cash flows to a market participant. Our impairment analysis is based on significant assumptions of future results, including operating and cash flow projections. Significant or sustained declines in future revenue or cash flows, or adverse changes in our business climate, among other factors, could result in the need to record an impairment charge in future periods.
Goodwill	Goodwill. We test goodwill for impairment on an annual basis, in our fourth quarter, or more frequently if circumstances indicate reporting unit carrying values may exceed their fair values. Circumstances that may indicate a reporting unit's carrying value exceeds its fair value include, but are not limited to: poor economic performance relative to historical or projected future operating results; significant negative industry, economic or company specific trends; changes in the manner of our use of the assets or the plans for our business; and loss of key personnel. When evaluating goodwill for impairment, based upon our annual test or due to changes in circumstances described above, we first perform a qualitative assessment to determine if the fair value of a reporting unit is more likely than not less than the reporting unit's carrying amount including goodwill. If this assessment indicates it is more likely than not, we then compare the carrying value of the reporting unit to the estimated fair value of the reporting unit. If the carrying value of the reporting unit exceeds the estimated fair value, we then calculate the implied estimated fair value of goodwill for the reporting unit and compare it to the carrying amount of goodwill for the reporting unit. If the carrying amount of goodwill exceeds the implied estimated fair value, an impairment charge to current operations is recorded to reduce the carrying value to implied estimated value. Significant judgment is required in determining the reporting units and assessing fair value of the reporting units.
Fair Value	Fair Value. Fair value is the price that would be received from selling an asset or paid in transfering a liability in an orderly transaction between market participants at the measurement date. Our fair value measurements consider the principal or most advantageous market in which we would transact and the market-based risk measurements or assumptions that market participants would use in pricing the asset or liability, such as inherent risk, transfer restrictions and credit risk. Fair values are determined based on three levels of inputs: • Level 1: Quoted prices in active markets for identical assets or liabilities • Level 2: Directly or indirectly observed inputs for the asset or liability, including quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active • Level 3: Significant unobservable inputs that reflect our own estimates of assumptions that market participants would use
Research and Development	Research and Development. Costs incurred in research and development are expensed as incurred. Software development costs are capitalized when a product’s technological feasibility has been established through the date the product is available for general release to customers. Other than internal use software, we have not capitalized any software development costs, as technological feasibility is generally not established until a working model is completed, at which time substantially all development is complete.
Revenue Recognition	Revenue Recognition. We recognize revenue when persuasive evidence of an arrangement exists, delivery has occurred, the sales price is fixed or determinable, and collection is probable. Physical products are considered delivered to the customer once they have been shipped and title and risk of loss have been transferred. For online sales, the products or services are considered delivered at the time the products or services are made available, digitally, to the end user. We recognize revenue on a gross or net basis. In most arrangements, we contract directly with end user customers, and are the primary obligor. In such arrangements, we recognize revenue on a gross basis. In some cases, we utilize third-party distributors who are the primary obligor to sell products or services directly to end user customers. In such instances, we recognize revenue on a net basis. In our direct to consumer operations, we derive revenue through (1) subscriptions sold by our Games segment and subscriptions of SuperPass within our Consumer Media segment, (2) sales of content downloads, software and licenses offered by our Consumer Media, Mobile Services, and Games segments and (3) the sale of advertising and the distribution of third-party products on our websites and in our games. Consumer subscription products are paid in advance, typically for monthly, quarterly or annual duration. Subscription revenue is recognized ratably over the related subscription time period. Revenue from sales of content downloads, software and licenses is recognized at the time the product is made available, digitally, to the end user. Revenue generated from advertising on our websites and from advertising and the distribution of third-party products included in our products is recognized as revenue at the time of delivery. We also generate revenue through business-to-business channels by providing services within our Mobile Services segment enabling mobile carriers to deliver audio and video content to their customers and by selling software licenses and products and related support and other services. Revenue generated from services provided to mobile carriers that enable the delivery of audio and video content to their customers is recognized as the services are provided. Setup fees to build these services are recognized ratably upon launch of the service over the remaining expected term of the service. Non-software revenue arrangements containing multiple elements are divided into separate units of accounting, after being evaluated for specific criteria. If the criteria for separation are met, revenue is allocated to the individual units using the relative fair value method. If the criteria are not met, the elements are treated as one unit of accounting and revenue recognition is delayed until all elements have been delivered. In the case of revenue arrangements containing software, elements are divided into separate units of accounting only when vendor-specific objective evidence has been established. In cases where vendor-specific objective evidence has not been established, undelivered elements are combined into one unit of accounting and are not recognized in revenue until all elements have been delivered.
Advertising Expenses	Advertising Expenses. We expense the cost of advertising and promoting our products as incurred.
Foreign Currency	Foreign Currency. The functional currency of the Company’s foreign subsidiaries is generally the currency of the country in which the subsidiary operates. Assets and liabilities of foreign operations are translated into U.S. dollars using rates of exchange in effect at the end of the reporting period. The net gain or loss resulting from translation is shown as translation adjustment and included in Accumulated Other Comprehensive Income (AOCI) in shareholders’ equity. Income and expense accounts are translated into U.S. dollars using average rates of exchange. Gains and losses from foreign currency transactions are included in the consolidated statements of operations.
Derivative Financial Instruments
Accounting for Taxes Collected from Customers	Accounting for Taxes Collected from Customers. Our revenues are reported net of sales and other transaction taxes that are collected from customers and remitted to taxing authorities.
Income Taxes	Income Taxes. We compute income taxes using the asset and liability method, under which deferred income taxes are provided for temporary differences between financial reporting basis and tax basis of our assets and liabilities and operating loss and tax credit carryforwards. We record a valuation allowance when it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of the deferred tax assets depends on the ability to generate sufficient taxable income of the appropriate character in the appropriate taxing jurisdictions. Adjustments to the valuation allowance could be required in the future if we estimate that the amount of deferred tax assets to be realized is more or less than the net amount we have recorded. Any increase or decrease in the valuation allowance could have the effect of increasing or decreasing the income tax provision in the statement of operations. Deferred tax assets and liabilities and operating loss and tax credit carryforwards are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences and operating loss and tax credit carryforwards are expected to be recovered or settled. We file numerous consolidated and separate income tax returns in the U.S. including federal, state and local, as well as foreign jurisdictions. With few exceptions, we are no longer subject to U.S. federal income tax examinations for tax years before 2013 or state, local, or foreign income tax examinations for years before 1993. We are currently under audit by various states and foreign jurisdictions for certain tax years subsequent to 1993. We recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. We recognize accrued interest and penalties related to uncertain tax positions as a component of income tax expense.
Stock-Based Compensation	Stock-Based Compensation. Stock-based compensation cost is measured at the grant date based on the fair value of the award and is recognized as expense over the requisite service period, which is the vesting period. We use the Black-Scholes option-pricing model or other appropriate valuation models such as Monte Carlo simulation to determine the fair value of stock-based option awards. The fair value of restricted stock awards is based on the closing market price of our common stock on the grant date of the award. Generally, we recognize the compensation cost for awards on a straight-line basis for the entire award, over the applicable vesting period. For performance-based awards, expense is recognized when it is probable the performance goal will be achieved, however if the likelihood becomes improbable, that expense is reversed. For market-based stock options, fair value is measured at the grant date using the Monte Carlo simulation model and we recognize compensation cost for these awards on a straight-line basis over the requisite service period for each separately vesting portion of the awards. For our employee stock purchase plan, compensation expense is measured based on the discount the employee is entitled to upon purchase. The valuation models for stock-based option awards require various judgmental assumptions including volatility in our common stock price and expected option life. If any of the assumptions used in the valuation models change significantly, stock-based compensation expense for new awards may differ materially in the future from the amounts recorded in the consolidated statements of operations. For all awards, we also estimate forfeitures at the time of grant and revise those estimates in subsequent periods if actual forfeitures differ from those estimates.
Net Income Per Share	Net Income Per Share. Basic net income (loss) per share (EPS) is computed by dividing net income (loss) by the weighted average number of common shares outstanding during the period. Diluted EPS is computed by dividing net income (loss) by the weighted average number of common and dilutive potential common shares outstanding during the period.
Recent Accounting Pronouncements	In May 2014, the Financial Accounting Standards Board (FASB) issued new revenue recognition guidance, which was subsequently updated and amended in 2015 and 2016. The guidance requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The new guidance will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. The guidance permits two methods of adoption: the full retrospective method where the standard would be applied to each prior reporting period presented and the cumulative effect of applying the standard would be recognized at the earliest period shown, or the modified retrospective method, where the cumulative effect of applying the standard would be recognized at the date of initial application. We will adopt the requirements of the new standard effective January 1, 2018, and will use the modified retrospective transition method with the cumulative effect to the opening balance of retained earnings recognized as of the date of initial adoption. Under the new standard, the greatest impact will be in certain areas where we will be required to estimate usage which drives the underlying revenue. Under the current guidance, we do not recognize revenues until we achieve fixed and determinable status, which would typically be at a later date. We also expect an impact related to the licensing of our RealTimes and RealPlayer products. As we transition to the new revenue standard, we will recognize the revenue predominantly at the time of delivery rather than over the contract period, which results in an acceleration of revenue. Revenue recognition for all other product lines will not be be significantly impacted. The new standard will not have a cash impact and will not affect the economics of the underlying customer contracts. Our disclosures in our notes to the Consolidated Financial Statements related to revenue recognition will be significantly expanded under the new standard, specifically around the quantitative and qualitative information about our underlying performance obligations. Our assessment of impacts resulting from the new standard is substantially complete, including the impact on our controls and differences in the timing or method of revenue recognition for our contracts. As a result of our evaluation, we have modified certain accounting policies and practices and updated certain existing controls. We also designed and implemented specific controls over our evaluation of the impact of the new standard, including our calculation of the cumulative adjustment to Retained Deficit. As a result of the new standard, based on currently executed contracts, we expect to record a cumulative adjustment increasing our Retained Deficit on January 1, 2018 of approximately $1.0 million to $1.5 million . In February 2016, the FASB issued new guidance related to the accounting for leases by lessees. A major change in the new guidance is that lessees will be required to present right-of-use assets and lease liabilities on the balance sheet. The new guidance will be effective for us on January 1, 2019, including interim periods within 2019. We will continue to evaluate the effect that the guidance will have on our consolidated financial statements and related disclosures. We expect that the guidance will result in a material change to our Consolidated Balance Sheet as a result of capitalizing certain of our operating leases. In November 2016, the FASB issued new guidance on the classification and presentation of changes in restricted cash on the statement of cash flows. This guidance is effective for interim and annual reporting for us on January 1, 2018. We do not expect the adoption of this guidance to have a material qualitative impact on our statement of cash flows. In January 2017, the FASB issued new guidance simplifying the test for goodwill impairment. The new guidance eliminates Step 2 from the goodwill impairment test, instead requiring an entity to recognize a goodwill impairment charge for the amount by which the reporting unit's carrying amount exceeds the reporting unit's fair value. This guidance is effective for interim and annual goodwill impairment tests beginning on December 15, 2019, with early adoption permitted. We will be evaluating the impact of the guidance, but do not currently expect the adoption to have a material impact on our consolidated financial statements and related disclosures. There have been no other recent accounting pronouncements or changes in accounting pronouncements to be implemented that are of significance or potential significance to RealNetworks.
