Organization Consolidation And Presentation Of Financial Statements [Abstract]
Organization, Basis of Presentation and Summary of Significant Accounting Policies	1. Organization, Basis of Presentation and Summary of Significant Accounting Policies The Company Smith Micro Software, Inc. (“Smith Micro,” “Company,” “we,” “us,” and “or”) develops software to simplify and enhance the mobile experience, providing solutions to leading wireless service providers, device manufacturers, and enterprise businesses around the world. From optimizing wireless networks to uncovering customer experience insights, and from streamlining Wi-Fi access to ensuring family safety, our solutions enrich connected lifestyles while creating new opportunities to engage consumers via smartphones. Our portfolio also includes a wide range of products for creating, sharing, and monetizing rich content, such as visual messaging, video streaming, and 2D/3D graphics applications. With this as a focus, it is Smith Micro’s mission to help our customers thrive in a connected world. Over the past three decades, Smith Micro has developed deep expertise in embedded software for mobile devices, policy-based management platforms, and highly-scalable client and server applications. Tier 1 mobile network operators, cable providers, OEMs/device manufacturers, and enterprise businesses across a wide range of industries use our software to capitalize on the growth of connected consumers and the Internet of Things (“IoT”). In general, we help our customers: • Optimize networks, reduce operational costs, and deliver “best-connected” user experiences; • Manage mobile devices over-the-air for maximum performance, efficiency, reliability and cost-effectiveness; • Provide greater insight into the mobile user experience to improve service quality and customer loyalty; • Engage and grow high-value relationships with their customers using smartphones. We continue to innovate and evolve our business to take advantage of industry trends and opportunities in emerging markets, such as “Big Data” analytics, the explosion of Wi-Fi hotspots, and business-to-consumer (“B2C”) mobile marketing and advertising. The key to our longevity, however, is not simply technology innovation, but a never-ending focus on customer value. Basis of Presentation The accompanying consolidated financial statements reflect the operating results and financial position of Smith Micro and its wholly owned subsidiaries in accordance with accounting principles generally accepted in the United States of America. All intercompany amounts have been eliminated in consolidation. Foreign Currency Transactions The Company has international operations resulting from current and prior year acquisitions. The countries in which the Company has a subsidiary or branch office in are Serbia, Sweden, Portugal, the United Kingdom and Canada. The functional currency for all of these foreign entities is the U.S. dollar in accordance with the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic No. 830-30, Foreign Currency Matters-Translation of Financial Statements Business Combinations The Company applies the provisions of FASB ASC Topic No. 805, Business Combinations , in the accounting for its acquisitions, which requires recognition of the assets acquired and the liabilities assumed at their acquisition date fair values, separately from goodwill. Goodwill as of the acquisition date is measured as the excess of consideration transferred over the net of the acquisition date fair values of the tangible and identifiable intangible assets acquired and liabilities assumed. While the Company uses its best estimates and assumptions to accurately value assets acquired and liabilities assumed at the acquisition date as well as contingent consideration, where applicable, its estimates are inherently uncertain and subject to refinement. As a result, during the measurement period that exists up to twelve months from the acquisition date, the Company may record adjustments to the tangible and specifically identifiable intangible assets acquired and liabilities assumed with a corresponding adjustment to goodwill in the reporting period in which the adjusted amounts are determined. Upon the conclusion of the measurement period or final determination of the values of assets acquired and liabilities assumed, whichever comes first, the impact of any subsequent adjustments is included in the consolidated statements of operations. Costs to exit or restructure certain activities of an acquired company or the Company’s internal operations are accounted for as a one-time termination and exit cost pursuant to FASB ASC Topic No. 420, Exit or Disposal Cost Obligations , and are accounted for separately from the business combination. A liability for costs associated with an exit or disposal activity is recognized and measured at its fair value in the Company’s consolidated statement of operations in the period in which the liability is incurred. Uncertain income tax positions and tax-related valuation allowances that are acquired in connection with a business combination are initially estimated as of the acquisition date. The Company reevaluates these items quarterly based upon facts and circumstances that existed as of the acquisition date, with any adjustments to the preliminary estimates being recorded to goodwill if such adjustments occur within the 12-month measurement period. Subsequent to the end of the measurement period or the Company’s final determination of the value of the tax allowance or contingency, whichever comes first, changes to these uncertain tax positions and tax-related valuation allowances will affect the provision for income taxes in the consolidated statement of operations, and could have a material impact on results of operations and financial position. Use of Estimates The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the U.S. requires management to make estimates and assumptions that affect the reported amounts in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. Fair Value of Financial Instruments The Company measures and discloses fair value measurements as required by FASB ASC Topic No. 820, Fair Value Measurements and Disclosures Fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that is determined based on assumptions that market participants would use in pricing an asset or a liability. As a basis for considering such assumptions, the FASB establishes a three-tier value hierarchy, which prioritizes the inputs used in the valuation methodologies in measuring fair value: • Level 1 - Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets. • Level 2 - Include other inputs that are directly or indirectly observable in the marketplace. • Level 3 - Unobservable inputs which are supported by little or no market activity. The fair value hierarchy also requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. As required by FASB ASC Topic No. 820, we measure our cash equivalents and short-term investments at fair value. Our cash equivalents and short-term investments are classified within Level 1 by using quoted market prices utilizing market observable inputs. As required by FASB ASC Topic No. 825, Financial Instruments Investments-Debt and Equity Securities As required by FASB ASC Topic No. 350, for goodwill and other intangibles impairment analysis, we utilize fair value measurements which are categorized within Level 3 of the fair value hierarchy. Our warrant liability is classified within Level 3 as some of the inputs to our valuation model are either not observable quoted prices or are not derived principally from or corroborated by observable market data by correlation or other means. The carrying values of all other assets and liabilities approximate fair value As required by FASB ASC Topic No. 820, we measure our warrant liability at fair value. Our warrant liability is classified within Level 3 as some of the inputs to our valuation model are either not observable quoted prices or are not derived principally from or corroborated by observable market data by correlation or other means. The carrying values of all other assets and liabilities approximate fair value. Significant Concentrations For the year ended December 31, 2016, two customers, each accounting for over 10% of revenues, made up 76.1% of revenues and 80% of accounts receivable, and one service provider with more than 10% of purchases totaled 24% of accounts payable. For the year ended December 31, 2015, two customers, each accounting for over 10% of revenues, made up 76.7% of revenues and 83% of accounts receivable, and one service provider with more than 10% of purchases totaled 13% of accounts payable. For the year ended December 31, 2014, two customers, each accounting for over 10% of revenues, made up 79.2% of revenues and 87% of accounts receivable, and one service provider with more than 10% of purchases totaled 27% of accounts payable. Cash and Cash Equivalents Cash and cash equivalents generally consist of cash, government securities, mutual funds, and money market funds. These securities are primarily held in two financial institutions and are uninsured except for the minimum Federal Deposit Insurance Corporation coverage, and have original maturity dates of three months or less. As of December 31, 2016 and 2015, bank balances totaling approximately $2.1 million and $8.5 million, respectively, were uninsured. Short-Term Investments Short-term investments have consisted of corporate notes, bonds, and commercial paper and U.S. government agency and government sponsored enterprise obligations. The Company accounts for these short-term investments as required by FASB ASC Topic No. 320, Investments-Debt and Equity Securities. These debt and equity securities are not classified as either held-to-maturity securities or trading securities. As such, they are classified as available-for-sale securities. Available-for-sale securities are recorded at fair value, with unrealized gains or losses recorded as a separate component of accumulated other comprehensive income in stockholders’ equity until realized. Accounts Receivable and Allowance for Doubtful Accounts We sell our products worldwide. We perform ongoing credit evaluations of our customers and adjust credit limits based upon payment history, the customer’s current credit worthiness and various other factors, as determined by our review of their current credit information. We continuously monitor collections and payments from our customers. We estimate credit losses and maintain an allowance for doubtful accounts reserve based upon these estimates. While such credit losses have historically been within our estimated reserves, we cannot guarantee that we will continue to experience the same credit loss rates that we have in the past. If not, this could have an adverse effect on our consolidated financial statements. Allowances for product returns are included in other adjustments to accounts receivable on the accompanying consolidated balance sheets. Product returns are estimated based on historical experience and have also been within management’s estimates. Inventories Inventories consist principally of compact disks (“CDs”), boxes and manuals and are stated at the lower of cost (determined by the first-in, first-out method) or market. The Company regularly reviews its inventory quantities on hand and records a provision for excess and obsolete inventory based primarily on management’s forecast of product demand and production requirements. At December 31, 2016 and 2015, our net inventory of $12,000 and $39,000 respectively, consisted mostly of components. Equipment and Improvements Equipment and improvements are stated at cost. Depreciation is computed using the straight-line method based on the estimated useful lives of the assets, generally ranging from three to seven years. Leasehold improvements are amortized using the straight-line method over the shorter of the estimated useful life of the asset or the lease term. Internal Software Development Costs Development costs incurred in the research and development of new software products and enhancements to existing software products are expensed as incurred until technological feasibility has been established. The Company considers technological feasibility to be established when all planning, designing, coding, and testing has been completed according to design specifications. After technological feasibility is established, any additional costs are capitalized. Through December 31, 2016, software has been substantially completed concurrently with the establishment of technological feasibility; accordingly, no costs have been capitalized to date. Impairment or Disposal of Long Lived Assets Long-lived assets to be held are reviewed for events or changes in circumstances which indicate that their carrying value may not be recoverable. They are tested for recoverability using undiscounted cash flows to determine whether or not impairment to such value has occurred as required by FASB ASC Topic No. 360, Property, Plant, and Equipment Goodwill In accordance with FASB ASC Topic No. 350, Intangibles-Goodwill and Other Intangible Assets and Amortization Amortization expense related to other intangibles acquired in acquisitions is calculated on a straight line basis over the useful lives. Derivative Liabilities The Company analyzes all financial instruments with features of both liabilities and equity under FASB ASC Topic No. 480, Distinguishing Liabilities From Equity Derivatives and Hedging Deferred Rent and Other Long-Term Liabilities The long-term liabilities are for deferred rent to account for the difference between straight-line and bargain rents, lease incentives included in deferred rent, restructuring expenses, and sublease deposits. Going Concern Evaluation In connection with preparing consolidated financial statements for the year ended December 31, 2016, management evaluated whether there were conditions and events, considered in the aggregate, that raised substantial doubt about the Company’s ability to continue as a going concern within one year from the date that the financial statements are issued. The Company considered the following: • Operating losses for seven consecutive quarters. • Negative cash flow from operating activities for three consecutive quarters. • Depressed stock price resulting in being non-compliant with NASDAQ listing rules to maintain a stock price of $1.00/share resulting in the necessity to execute a 1:4 reverse stock split. • Loss of 32% of revenue from our number one customer, Sprint, in fiscal year 2016 versus fiscal year 2015. Ordinarily, conditions or events that raise substantial doubt about an entity’s ability to continue as a going concern relate to the entity’s ability to meet its obligations as they become due. The Company evaluated its ability to meet its obligations as they become due within one year from the date that the financial statements are issued by considering the following: • The Company raised $4.0 million of debt financing during the year ended December 31, 2016. • The Company has been able to raise capital from short-term loans from its Board members. • As a result of the Company’s restructuring that was implemented during the three months ended December 31, 2016, and again during the first quarter of fiscal 2017, the Company’s cost structure is now in line with its current baseline revenue projections. See Footnote 3 for additional details regarding restructuring. Management believes that the Company will generate enough cash from operations to satisfy its obligations for the next twelve months. The Company will take the following actions if it starts to trend unfavorable to its internal profitability and cash flow projections, in order to mitigate conditions or events that would raise substantial doubt about its ability to continue as a going concern: • Raise additional capital through short-term loans. • Implement additional restructuring and cost reductions. • Raise additional capital through a private placement. • Secure a commercial bank line of credit. • Dispose of one or more product lines. • Sell or license intellectual property. Revenue Recognition We currently report our net revenues under two operating groups: Wireless and Graphics. Within each of these groups, software revenue is recognized based on the customer and contract type. We recognize revenue when persuasive evidence of an arrangement exists, delivery has occurred, the price is fixed and determinable, and collectability is probable as required by FASB ASC Topic No. 605-985, Revenue Recognition-Software We have a few multiple element agreements for which we have contracted to provide a perpetual license for use of proprietary software, to provide non-recurring engineering, and in some cases, to provide software maintenance (post contract support). For these software and software-related multiple element arrangements, we must: (1) determine whether and when each element has been delivered; (2) determine whether undelivered products or services are essential to the functionality of the delivered products and services; (3) determine the fair value of each undelivered element using vendor-specific objective evidence (“VSOE”); and (4) allocate the total price among the various elements. VSOE of fair value is used to allocate a portion of the price to the undelivered elements and the residual method is used to allocate the remaining portion to the delivered elements. Absent VSOE, revenue is deferred until the earlier of the point at which VSOE of fair value exists for any undelivered element or until all elements of the arrangement have been delivered. However, if the only undelivered element is post contract support, the entire arrangement fee is recognized ratably over the performance period. We determine VSOE for each element based on historical stand-alone sales to third parties or from the stated renewal rate for the elements contained in the initial arrangement. In determining VSOE, we require that a substantial majority of the selling prices for a product or service fall within a reasonably narrow pricing range. We have established VSOE for our post contract support services and non-recurring engineering. On occasion, we enter into fixed fee arrangements, i.e. for trials, in which customer payments are tied to the achievement of specific milestones. Revenue for these contracts is recognized based on customer acceptance of certain milestones as they are achieved. We also enter hosting arrangements that sometimes include up-front, non-refundable set-up fees. Revenue is recognized for these fees over the term of the agreement. For Graphics sales, management reviews available retail channel information and makes a determination of a return provision for sales made to distributors and retailers based on current channel inventory levels and historical return patterns. Certain sales to distributors or retailers are made on a consignment basis. Revenue for consignment sales are not recognized until sell through to the final customer is established. Certain revenues are booked net of revenue sharing payments. Sales directly to end users are recognized upon shipment. End users have a thirty-day right of return, but such returns are reasonably estimable and have historically been immaterial. We also provide technical support to our customers. Such costs have historically been insignificant. Sales Incentives For our Graphics sales, the cost of sales incentives the Company offers without charge to customers that can be used in, or that are exercisable by a customer as a result of, a single exchange transaction is accounted for as a reduction of revenue as required by FASB ASC Topic No. 605-50, Revenue Recognition-Customer Payments and Incentives Advertising Expense Advertising costs are expensed as incurred. Advertising expenses were $0.5 million, $0.3 million, and $0.3 million for the years ended December 31, 2016, 2015, and 2014, respectively.

This effect is required to be calculated as if the accounting had been completed at the acquisition date. • An entity to present separately on the face of the income statement or disclose in the notes the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. The guidance was effective for financial statements issued for annual periods beginning after December 15, 2015, including interim periods within those fiscal years. The Company has adopted this standard and it did not have a material impact on the Company’s consolidated financial statements.

Business Combinations [Abstract]
Acquisitions	2. Acquisitions The Company applies the provisions of FASB ASC Topic No. 805, Business Combinations Costs to exit or restructure certain activities of an acquired company or the Company’s internal operations are accounted for as a one-time termination and exit cost pursuant to FASB ASC Topic No. 420, Exit or Disposal Cost Obligations, Uncertain income tax positions and tax-related valuation allowances that are acquired in connection with a business combination are initially estimated as of the acquisition date. The Company reevaluates these items quarterly based upon facts and circumstances that existed as of the acquisition date, with any adjustments to the preliminary estimates being recorded to goodwill if such adjustments occur within the 12-month measurement period. Subsequent to the end of the measurement period or the Company’s final determination of the value of the tax allowance or contingency, whichever comes first, changes to these uncertain tax positions and tax-related valuation allowances will affect the provision for income taxes in the consolidated statement of operations, and could have a material impact on results of operations and financial position. iMobileMagic – Mobile Experiences On July 19, 2016, the Company and iMobileMagic – Mobile Experiences, LDA (“iMM”), a Portuguese limited liability company, entered into a Share Purchase Agreement (the “Share Purchase Agreement”) pursuant to which the Company agreed to acquire 100% of the outstanding share capital (the “Shares”) of iMM.

Restructuring And Related Activities [Abstract]
Restructuring	3. Restructuring 2016 Restructuring In the fourth quarter of fiscal 2016, the Board of Directors approved a plan of restructuring intended to streamline and flatten the Company’s organization, reduce overall headcount by approximately 30%, and reduce its overall cost structure by approximately $2.5 million per quarter. The restructuring plan resulted in special charges totaling $0.3 million recorded during the three-month period ended December 31, 2016. These charges were for primarily related to severance costs and were all paid out by December 31, 2016. In the first quarter of fiscal 2017, the Board of Directors approved an additional restructuring plan intended to further streamline and flatten the Company’s organization, reduce overall headcount by approximately 16%, and reduce its overall cost structure by another $0.9 - $1.0 million per quarter. The restructuring plan will result in special charges totaling approximately $0.3 million to be recorded during the three-month period ending March 31, 2017. These charges are primarily related to severance costs and include $0.1 million of non-cash stock-based compensation severance. 2014 Restructuring On May 6, 2014, the Board of Directors approved a plan of restructuring intended to streamline and flatten the Company’s organization, reduce overall headcount by approximately 20%, and reduce its overall cost structure by approximately $2.0 million per quarter. The restructuring plan resulted in special charges totaling $1.8 million recorded during the three-month period ended June 30, 2014. These charges were for non-cash stock-based compensation expense of $1.3 million, severance costs for affected employees of $0.4 million, and other related costs of $0.1 million. 2013 Restructuring On July 25, 2013, the Board of Directors approved a plan of restructuring intended to bring the Company’s operating expenses better in line with revenues. The restructuring plan involved a realignment of organizational structures, facility consolidations/closures, and headcount reductions of approximately 26% of the Company’s worldwide workforce. The restructuring plan was implemented primarily during the three-month period ended September 30, 2013 and resulted in annualized savings of approximately $16.0 million. The restructuring plan resulted in special charges totaling $5.6 million recorded in the year ended December 31, 2013. These charges were for lease/rental terminations of $3.3 million, severance costs for affected employees of $1.1 million, equipment, and improvements write-offs as a result of our lease/rental terminations of $1.0 million and other related costs of $0.2 million. In the year ended December 31, 2014, we increased the reserve by $0.6 million due to changes in our assumptions on future sublease income on our lease terminations of $0.8 million, partially offset by adjustments to our one-time employee termination benefits.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	4. Fair Value of Financial Instruments The Company analyzes all financial instruments with features of both liabilities and equity under FASB ASC Topic No. 480, Distinguishing Liabilities From Equity Derivatives and Hedging At December 31, 2016 and December 31, 2015, the carrying value and the aggregate fair value of the Company’s warrant liability and long-term debt were as follows (in thousands): As of December 31, 2016 As of December 31, 2015 Carrying Amount Fair Value Carrying Amount Fair Value Liabilities: Warrant liability $ 1,210 $ 1,210 $ — $ — Long-term debt $ 1,934 $ 1,934 $ — $ — The warrants were accounted for as liabilities, with changes in the fair value included in net loss for the respective periods. Because some of the inputs to our valuation model were either not observable nor derived principally from or corroborated by observable market data by correlation or other means, the warrant liability is classified as a Level 3 in the fair value hierarchy. Our stock price can be volatile and there could be material fluctuations in the value of the warrants in future periods. A roll forward of our warrant liability classified as Level 3 and measured at fair value on a recurring basis is as follows (in thousands): Balance, December 31, 2015 $ — Issuances 2,120 Change in fair value of warrant liability (910 ) Balance, December 31, 2016 $ 1,210 Warrant Liability On September 2, 2016, we entered into a Note and Warrant Purchase Agreement with Unterberg Koller Capital Fund L.P. and William W. and Dieva L. Smith, pursuant to which the Company issued and sold to the Investors in a private placement senior subordinated promissory notes in the aggregate principal amount of $4,000,000 and five-year warrants to purchase an aggregate of 1,700,000 shares of the Company’s common stock at an exercise price of $2.74 per share, and expires five years from the date of issuance. The Company completed the transactions contemplated by the Purchase Agreement and issued the Notes and Warrants on September 6, 2016. We assessed the warrants and concluded that they should be recorded as a liability. The initial fair value of the warrant liability associated with the Note and Warrant Purchase Agreement was $2.1 million, and the fair value decreased to $1.2 million as of December 31, 2016. All changes in the fair value of warrants will be recognized in our consolidated statements of operations until they are either exercised or expire. The warrants are not traded in an active securities market, and as such the estimated fair value as of December 31, 2016 was determined by using an option pricing model (Black-Scholes) with the following assumptions: As of December Expected remaining term 4.75 years Common stock market price $ 1.57 Risk-free interest rate 1.96 % Expected volatility 70.5 % Resulting fair value (per warrant) $ 0.71 Expected volatility is based on historical volatility. Historical volatility was computed using monthly pricing observations for recent periods that correspond to the remaining expected term of the warrants. We believe this method produces an estimate that is representative of our expectations of future volatility over the expected term of these warrants. We currently have no reason to believe future volatility over the expected remaining life of these warrants is likely to differ materially from historical volatility. The expected life is based on the remaining contractual term of the warrants. The risk-free interest rate is the U.S. Treasury bond rate as of the valuation date. Long-Term Debt At December 31, 2016, the aggregate fair value and the carrying value of the Company’s long-term debt was as follows (in thousands): As of December 31, 2016 As of December 31, 2015 Carrying Amount Fair Value Carrying Amount Fair Value Long-term debt - related party $ 967 $ 967 $ — $ — Long-term debt 967 967 — — Total long-term debt $ 1,934 $ 1,934 $ — $ — The carrying value $1.9 million is net of debt discount of $1.9 million and debt issuance costs of $0.2 million as of December 31, 2016.

Other Assets These are office rent and other deposits. Intangible Assets The following table sets forth our acquired intangible assets by major asset class as of December 31, 2016 and December 31, 2015 (in thousands except for useful life data): December 31, 2016 December 31, 2015 Useful life Accumulated Net book value Impairment Net Accumulated Net (years) Gross amortization before impairment charge book value Gross amortization book value Purchased technology 5 -6 $ 265 $ (32 ) $ 233 $ — $ 233 $ — $ — $ — Customer relationships 3-6 999 (147 ) 852 (411 ) 441 — — — Trademarks/trade names 2 38 (9 ) 29 — 29 — — — Non-compete 3 51 (9 ) 42 — 42 — — — Total $ 1,353 $ (197 ) $ 1,156 $ (411 ) $ 745 $ — $ — $ — Intangible assets amortization expense was $0.1 million for the three and twelve months ended December 31, 2016. Future amortization expense related to intangible assets as of December 31, 2016 are as follows (in thousands): Year Ending December 31, 2017 259 2018 249 2019 143 2020 46 2021 40 Beyond 8 Total $ 745 Valuation of Goodwill and Intangible Assets The Company accounts for goodwill and intangible assets as required by FASB ASC Topic No. 350, Intangibles-Goodwill and Other • a determination that the carrying value of such assets cannot be recovered through undiscounted cash flows; • loss of legal ownership or title to the assets; • significant changes in our strategic business objectives and utilization of the assets; or • the impact of significant negative industry or economic trends. If the intangible assets are considered to be impaired, the impairment we recognize is the amount by which the carrying value of the intangible assets exceeds the fair value of the intangible assets. In addition, we base the useful lives and the related amortization expense on our estimate of the useful life of the intangible assets. Due to the numerous variables associated with our judgments and assumptions relating to the carrying value of our intangible assets and the effects of changes in circumstances affecting these valuations, both the precision and reliability of the resulting estimates are subject to uncertainty, and as additional information becomes known, we may change our estimate, in which case, the likelihood of a material change in our reported results would increase. The Company recognized an impairment loss of $0.4 million in the three and twelve months ended December 31, 2016 related to an intangible asset acquired from our Birdstep acquisition. We review the recoverability of the carrying value of goodwill at least annually or whenever events or circumstances indicate a potential impairment. Our annual impairment testing date is December 31. Recoverability of goodwill is determined by comparing the estimated fair value of our reporting units to the carrying value of the underlying net assets in the reporting units. If the estimated fair value of a reporting unit is determined to be less than the fair value of its net assets, goodwill is deemed impaired and an impairment loss is recognized to the extent that the carrying value of goodwill exceeds the difference between the estimated fair value of the reporting unit and the fair value of its other assets and liabilities. We determined that we did not have any impairment of goodwill at December 31, 2016.

Of the $134.6 million of NOL carryforwards at December 31, 2016, $0.8 million relates to the excess tax benefits from employee restricted stock. Equity will be increased by $0.8 million, if and when such excess tax benefits are ultimately realized. These federal NOL carryforwards will expire from 2024 through 2036 and state NOL carryforwards will expire 2016 through 2036. The Company also had $0.5 million of Alternative minimum tax credit carryforwards with an indefinite life, available to offset regular federal income tax requirements. The Company has federal and state tax credit carryforwards of approximately $2.5 million and $0.7 million, respectively, at December 31, 2016. These tax credits will begin to expire in 2027. To the extent that an ownership change has occurred under Internal Revenue Code Sections 382 and 383, the Company’s use of its loss carryforwards and credit carryforwards to offset future taxable income may be limited. At December 31, 2016 and 2015, the Company had unrecognized tax benefits, including interest and penalties of approximately $0.4 million and $0.6 million for as of December 31, 2016 and 2015, respectively. The Company’s gross unrecognized tax benefits as of December 31, 2016 and 2015 and the changes in those balances are as follows (in thousands): Year Ended December 31, 2016 2015 Beginning balance $ 592 $ 592 Increases/(decreases) in tax positions for the current year (164 ) — Increases/(decreases) in tax positions for the prior year — — Gross unrecognized tax benefits, ending balance $ 428 $ 592 We account for income taxes as required by FASB ASC Topic No. 740, Income Taxes The Company assesses whether a valuation allowance should be recorded against its deferred tax assets based on the consideration of all available evidence, using a “more likely than not” realization standard. The four sources of taxable income that must be considered in determining whether deferred tax assets will be realized are: (1) future reversals of existing taxable temporary differences (i.e., offset of gross deferred tax liabilities against gross deferred tax assets); (2) taxable income in prior carryback years, if carryback is permitted under the applicable tax law; (3) tax planning strategies; and (4) future taxable income exclusive of reversing temporary differences and carryforwards. After a review of the four sources of taxable income as of December 31, 2016 (as described above), and after consideration of the Company’s continuing cumulative loss position as of December 31, 2016, the Company recorded a valuation allowance related to its U.S.-based deferred tax assets of $76.3 million at December 31, 2016. During fiscal year 2016, the valuation allowance on deferred tax assets increased by $1.4 million and decreased $0.8 million during fiscal years 2015 and 2014 million and $12.1 million, respectively. We recognized interest and penalties accrued related to unrecognized tax benefits in income tax expense. During the fiscal years 2016 and 2015, we recognized approximately $0 and $3,000 of interest and penalties in each year. The cumulative interest and penalties at December 31, 2016 and 2015 were $0 and $47,000, respectively. Unrecognized tax benefits of $164 million were released in October of 2016, which impacted the effective tax rate due to the expiration of the statute of limitations. We do not anticipate any material changes to unrecognized tax benefits within the next twelve months that will affect the effective tax rate. The Company is subject to U.S. federal income tax, as well as to income tax of multiple state jurisdictions. Federal income tax returns of the Company are subject to IRS examination for the 2012 – 2015 tax years. State income tax returns are subject to examination for a period of three to four years after filing. As of December 31, 2016, the Company had no outstanding tax audits. The outcome of tax audits cannot be predicted with certainty. If any issues addressed in the Company’s tax audits are resolved in a manner not consistent with management’s expectations, the Company could be required to adjust its provision for income tax in the period such resolution occurs.

Total rent expense was $1.6 million, $1.3 million and $1.2 million for the years ended December 31, 2016, 2015, and 2014, respectively. As a condition of our lease in Pittsburgh, the landlord agreed to incentives of $40.00 per square foot, or a total of $2.2 million, for improvements to the space. These costs have been included in deferred rent in our long-term liabilities and are being amortized over the remaining lease term. Pennsylvania Opportunity Grant Program On September 26, 2011, we received $1.0 million from the State of Pennsylvania to help fund our agreement to start-up a new facility. The grant carried with it an obligation, or commitment, to employ at least 232 people within a three-year time period that ended on December 31, 2013. We received an extension of time to meet this employment commitment by April 30, 2016. The grant contained conditions that would require us to return a pro-rata amount of the monies received if we failed to meet these conditions. As such, the monies had been recorded as a liability in the accrued liabilities line item on the balance sheet until we are irrevocably entitled to retain the monies, or until it is determined that we need to return a portion or all of the monies received. On June 27, 2016, we received a letter from the State of Pennsylvania requesting reimbursement of $0.3 million and said we earned the remaining $0.7 million of the original $1.0 million grant. On September 19, 2016, we entered into a Settlement and Release Agreement with the Commonwealth of Pennsylvania, acting by and through the Department of Community and Economic Development (“DCED”) to repay $0.3 million of the original $1.0 million grant. Per the agreement, the total amount due of $0.3 million is at 0% interest and is payable in twenty equal quarterly installments commencing on January 31, 2017 and ending on October 31, 2021. Litigation The Company may become involved in various legal proceedings arising from its business activities. While management does not believe the ultimate disposition of these matters will have a material adverse impact on the Company’s consolidated results of operations, cash flows, or financial position, litigation is inherently unpredictable, and depending on the nature and timing of these proceedings, an unfavorable resolution could materially affect the Company’s future consolidated results of operations, cash flows, or financial position in a particular period. Other Contingent Contractual Obligations During its normal course of business, the Company has made certain indemnities, commitments, and guarantees under which it may be required to make payments in relation to certain transactions. These include: intellectual property indemnities to the Company’s customers and licensees in connection with the use, sale and/or license of Company products; indemnities to various lessors in connection with facility leases for certain claims arising from such facility or lease; indemnities to vendors and service providers pertaining to claims based on the negligence or willful misconduct of the Company; indemnities involving the accuracy of representations and warranties in certain contracts; and indemnities to directors and officers of the Company to the maximum extent permitted under the laws of the State of Delaware. In addition, the Company has made contractual commitments to employees providing for severance payments upon the occurrence of certain prescribed events. The Company may also issue a guarantee in the form of a standby letter of credit as security for contingent liabilities under certain customer contracts. The duration of these indemnities, commitments, and guarantees varies, and in certain cases, may be indefinite. The majority of these indemnities, commitments and guarantees may not provide for any limitation of the maximum potential for future payments the Company could be obligated to make. The Company has not recorded any liability for these indemnities, commitments, and guarantees in the accompanying consolidated balance sheets.

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]
Stock-Based Compensation	10. Stock-Based Compensation Stock Plans On June 18, 2015, our Shareholders approved the 2015 Omnibus Equity Incentive Plan (“2015 OEIP”). The 2015 OEIP, which became effective the same date, replaced the 2005 Stock Option / Stock Issuance Plan (“2005 Plan”) which was due to expire on July 28, 2015. All outstanding options under the 2005 Plan remain outstanding, but no new grants will be made under that Plan. The maximum number of shares of the Company’s common stock available for issuance over the term of the 2015 OEIP may not exceed 2,125,000 shares. The 2015 Plan provides for the issuance of full value awards (restricted stock, performance stock, dividend equivalent right or restricted stock units) and not full value awards (stock options or stock appreciation rights) to employees, non-employee members of the board and consultants. Any full value award settled in shares will be debited as 1.2 shares and not full value awards settled in shares will be debited as 1.0 shares against the share reserve. The exercise price per share for option grants is not to be less than the fair market value per share of the Company’s common stock on the date of grant. The Board of Directors has the discretion to determine the vesting schedule. Options may be exercisable immediately or in installments, but generally vest over a four-year period from the date of grant. In the event the holder ceases to be employed by the Company, all unvested options terminate and all vested options may be exercised within a period following termination. In general, options expire ten years from the date of grant. Restricted stock is valued using the closing stock price on the date of the grant. The total value is expensed over the vesting period of 12 to 48 months. Employee Stock Purchase Plan The Company has a shareholder approved employee stock purchase plan (“ESPP”), under which substantially all employees may purchase the Company’s common stock through payroll deductions at a price equal to 85% of the lower of the fair market values of the stock as of the beginning and end of six-month offering periods. An employee’s payroll deductions under the ESPP are limited to 10% of the employee’s compensation and employees may not purchase more than the lesser of $25,000 of stock, or 250 shares, for any purchase period. Additionally, no more than 250,000 shares may be purchased under the plan. Stock Compensation Expense The Company accounts for all stock-based payment awards made to employees and directors based on their fair values and recognized as compensation expense over the vesting period using the straight-line method over the requisite service period for each award as required by FASB ASC Topic No. 718, Compensation-Stock Compensation Valuation of Stock Option and Restricted Stock Awards The assumptions used to compute the share-based compensation costs for the stock options granted during the years ended December 31, 2016, 2015, and 2014, respectively, using the Black-Scholes option pricing model, were as follows: Year Ended December 31, 2016 2015 2014 Weighted average grant-date fair value of stock options $ 1.40 $ 3.08 $ 2.28 Assumptions Risk-free interest rate (weighted average) 1.1 % 1.1 % 1.2 % Expected dividend yield — — — Weighted average expected life (years) 4.8 4.0 3.5 Volatility (weighted average) 74.3 % 83.5 % 82.9 % Forfeiture rate 23.0 % 23.3 % 25.5 % The risk-free interest rate assumption was based on the United States Treasury’s rates for U.S. Treasury zero-coupon bonds with maturities similar to those of the expected term of the award being valued. The Company assumed no dividend yield because it does not expect to pay dividends for the foreseeable future. The weighted average expected life is the vesting period for those options granted during that period. The average volatility is based on the actual historical volatility of our common stock. The forfeiture rate was based on modified employee turnover. Grants of restricted stock are valued using the closing stock price on the date of grant. In the year ended December 31, 2016, a total of 75,000 shares of restricted stock, with a total value of $51,000, were granted to non-employee members of the Board of Directors. This cost will be amortized over a period of 12 months. In addition, 300,000 shares of restricted stock, with a total value of $0.9 million, were granted to key officers and employees of the Company. This cost will be amortized over a period of 48 months. Valuation of ESPP The fair values are estimated at the beginning of each offering period using a Black-Scholes valuation model that uses the assumptions noted in the following table. The risk-free rate is based on the U.S. treasury yield curve in effect at the time of grant. Expected volatility was based on the historical volatility on the day of grant. Following is a schedule of the shares purchased, the fair value per share, and the Black-Scholes model assumptions for each offering period: (Ending) September March 31, September 30, March 31, September 30, Offering Period Ended 2016 2016 2015 2015 2014 Shares purchased for offering period 3,536 3,498 3,113 2,804 3,405 Fair value per share $ 0.77 $ 1.24 $ 2.39 $ 1.72 $ 3.32 Assumptions Risk-free interest rate (average) 0.47 % 0.18 % 0.11 % 0.40 % 0.80 % Expected dividend yield — — — — — Weighted average expected life (years) 0.5 0.5 0.5 0.5 0.5 Volatility (average) 40.4 % 66.1 % 103.8 % 109.1 % 74.0 % Compensation Costs Non-cash stock-based compensation expenses related to stock options, restricted stock grants and the ESPP were recorded in the financial statements as follows (in thousands): Year Ended December 31, 2016 2015 2014 Cost of revenues $ 3 $ 12 $ 13 Selling and marketing 277 335 270 Research and development 495 644 659 General and administrative 753 1,167 1,437 Restructuring expense — — 1,273 Total non-cash stock compensation expense $ 1,528 $ 2,158 $ 3,652 Total share-based compensation for each year includes cash payment of income taxes related to grants of restricted stock in the amounts of $0, $0.1 million and $0.2 million for the years ended December 31, 2016, 2015, and 2014, respectively.

Preferred Stock	12. Preferred Stock On October 16, 2015, the Company entered into a Preferred Shares Rights Agreement (“Rights Agreement”) with Computershare Trust Company, N.A., as rights agent, in connection with a dividend distribution declared by the Company’s Board of Directors of one right (“Right”) for each outstanding share of common stock, par value $0.001 (“Common Shares”), per common share of the Company to stockholders of record as of the close of business on October 26, 2015 (“Record Date”). Each Right entitles the registered holder to purchase from the Company one one-thousandth of a share of Series A Participating Preferred Stock, par value $0.001 per share (“Preferred Shares”), of the Company at an exercise price of $6.69 per one one-thousandth of a Preferred Share, subject to adjustment. The Board adopted the Rights Agreement to protect stockholders from coercive or otherwise unfair takeover tactics. In general terms, it works by imposing a significant penalty upon any person or group that acquires 20% or more of the Common Shares without the approval of the Board. As a result, the overall effect of the Rights Agreement and the issuance of the Rights may be to render more difficult or discourage a merger, tender or exchange offer or other business combination involving the Company that is not approved by the Board. However, neither the Rights Agreement nor the Rights should interfere with any merger, tender or exchange offer or other business combination approved by the Board.

Smith (collectively, the “Investors”), pursuant to which the Company issued and sold Notes in the aggregate principal amount of $4,000,000 and five-year Warrants to purchase an aggregate of 1,700,000 shares of the Company’s common stock at an exercise price of $2.74 per share. The Company completed the transactions contemplated by the Purchase Agreement and issued the Notes and Warrants on September 6, 2016. The Notes mature three years following the issuance date, or September 6, 2019, and bear interest at the rate of 10% of the outstanding principal balance of the Notes, payable quarterly in cash or shares of the Company’s common stock at a conversion price equal to the greater of (i) the five-day volume weighted average closing price of the common stock on the Nasdaq Stock Market, measured on the third trading day prior to the date that interest is due, or (ii) the minimum price so that payment of interest for such installment in the form of common stock shall not constitute “equity compensation” to an officer, director, employee or consultant of the Company for purposes of Rule 5635(c) of the Nasdaq Stock Market or a private placement that, combined with the other securities issued or issuable under the Purchase Agreement, would require shareholder approval by the Company under Rule 5635(d) of the Nasdaq Stock Market. The Notes are subordinate and junior in right of payment to the prior payment in full of all claims, whether now existing or arising in the future, of holders of senior debt of the Company, as described in the Notes. Under the Notes, if an Acceleration Event occurs and shall be continuing, any Holder of the Notes, may by written notice delivered to the Secretary of the Company within ninety days after any occurrence of such Acceleration Event (an “Acceleration Notice”), declare the entire unpaid principal balance of the Note, together with all interest accrued, due and payable shall be accelerated and due and payable, without presentment, demand, protest, or notice (except for the delivery of an Acceleration Notice). For purposes of the Notes, an Acceleration Event shall occur if, while the Notes are outstanding, William W. Smith, Jr. (i) is not nominated for re-election as a director of the Company at the normal expiration of his term as director, (ii) is terminated or removed as Chairman of the Board of Directors of the Company, (iii) is terminated or removed as Chief Executive Officer of the Company or (iv) dies or becomes permanently disabled. An Acceleration Event shall not occur if Mr. Smith consents to any of the events referenced above or voluntarily resigns or retires from any of the positions listed. We allocated the aggregate proceeds of the senior subordinated promissory notes payable between the warrants and the debt obligations based on their fair values. In accordance with ASC 480 and ASC 815, the warrants were recorded as a liability and will be marked to market. The fair value of the warrants issued to the Lender was calculated utilizing the Black-Scholes option pricing model. The Black-Scholes option-pricing model incorporates various and highly sensitive assumptions including expected volatility, expected term and risk-free interest rates. The expected volatility is based on the historical volatility of the Company’s common stock over the most recent period. The risk-free interest rate for period within the contractual life of the warrant is based on the U.S. Treasury yield in effect at the time of grant. We will amortize the fair value of the warrants as a discount of $2.1 million over the term of the loan using the effective interest method, with an effective interest rate of 28.6%.

Foreign Currency Transactions	Foreign Currency Transactions The Company has international operations resulting from current and prior year acquisitions. The countries in which the Company has a subsidiary or branch office in are Serbia, Sweden, Portugal, the United Kingdom and Canada. The functional currency for all of these foreign entities is the U.S. dollar in accordance with the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic No. 830-30, Foreign Currency Matters-Translation of Financial Statements
Business Combinations	Business Combinations The Company applies the provisions of FASB ASC Topic No. 805, Business Combinations , in the accounting for its acquisitions, which requires recognition of the assets acquired and the liabilities assumed at their acquisition date fair values, separately from goodwill. Goodwill as of the acquisition date is measured as the excess of consideration transferred over the net of the acquisition date fair values of the tangible and identifiable intangible assets acquired and liabilities assumed. While the Company uses its best estimates and assumptions to accurately value assets acquired and liabilities assumed at the acquisition date as well as contingent consideration, where applicable, its estimates are inherently uncertain and subject to refinement. As a result, during the measurement period that exists up to twelve months from the acquisition date, the Company may record adjustments to the tangible and specifically identifiable intangible assets acquired and liabilities assumed with a corresponding adjustment to goodwill in the reporting period in which the adjusted amounts are determined. Upon the conclusion of the measurement period or final determination of the values of assets acquired and liabilities assumed, whichever comes first, the impact of any subsequent adjustments is included in the consolidated statements of operations. Costs to exit or restructure certain activities of an acquired company or the Company’s internal operations are accounted for as a one-time termination and exit cost pursuant to FASB ASC Topic No. 420, Exit or Disposal Cost Obligations , and are accounted for separately from the business combination. A liability for costs associated with an exit or disposal activity is recognized and measured at its fair value in the Company’s consolidated statement of operations in the period in which the liability is incurred. Uncertain income tax positions and tax-related valuation allowances that are acquired in connection with a business combination are initially estimated as of the acquisition date. The Company reevaluates these items quarterly based upon facts and circumstances that existed as of the acquisition date, with any adjustments to the preliminary estimates being recorded to goodwill if such adjustments occur within the 12-month measurement period. Subsequent to the end of the measurement period or the Company’s final determination of the value of the tax allowance or contingency, whichever comes first, changes to these uncertain tax positions and tax-related valuation allowances will affect the provision for income taxes in the consolidated statement of operations, and could have a material impact on results of operations and financial position.
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the U.S. requires management to make estimates and assumptions that affect the reported amounts in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates.
Fair Value of Financial Instruments	Fair Value of Financial Instruments The Company measures and discloses fair value measurements as required by FASB ASC Topic No. 820, Fair Value Measurements and Disclosures Fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that is determined based on assumptions that market participants would use in pricing an asset or a liability. As a basis for considering such assumptions, the FASB establishes a three-tier value hierarchy, which prioritizes the inputs used in the valuation methodologies in measuring fair value: • Level 1 - Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets. • Level 2 - Include other inputs that are directly or indirectly observable in the marketplace. • Level 3 - Unobservable inputs which are supported by little or no market activity. The fair value hierarchy also requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. As required by FASB ASC Topic No. 820, we measure our cash equivalents and short-term investments at fair value. Our cash equivalents and short-term investments are classified within Level 1 by using quoted market prices utilizing market observable inputs. As required by FASB ASC Topic No. 825, Financial Instruments Investments-Debt and Equity Securities As required by FASB ASC Topic No. 350, for goodwill and other intangibles impairment analysis, we utilize fair value measurements which are categorized within Level 3 of the fair value hierarchy. Our warrant liability is classified within Level 3 as some of the inputs to our valuation model are either not observable quoted prices or are not derived principally from or corroborated by observable market data by correlation or other means. The carrying values of all other assets and liabilities approximate fair value As required by FASB ASC Topic No. 820, we measure our warrant liability at fair value. Our warrant liability is classified within Level 3 as some of the inputs to our valuation model are either not observable quoted prices or are not derived principally from or corroborated by observable market data by correlation or other means. The carrying values of all other assets and liabilities approximate fair value.
Significant Concentrations	Significant Concentrations For the year ended December 31, 2016, two customers, each accounting for over 10% of revenues, made up 76.1% of revenues and 80% of accounts receivable, and one service provider with more than 10% of purchases totaled 24% of accounts payable. For the year ended December 31, 2015, two customers, each accounting for over 10% of revenues, made up 76.7% of revenues and 83% of accounts receivable, and one service provider with more than 10% of purchases totaled 13% of accounts payable. For the year ended December 31, 2014, two customers, each accounting for over 10% of revenues, made up 79.2% of revenues and 87% of accounts receivable, and one service provider with more than 10% of purchases totaled 27% of accounts payable.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents generally consist of cash, government securities, mutual funds, and money market funds. These securities are primarily held in two financial institutions and are uninsured except for the minimum Federal Deposit Insurance Corporation coverage, and have original maturity dates of three months or less. As of December 31, 2016 and 2015, bank balances totaling approximately $2.1 million and $8.5 million, respectively, were uninsured.
Short-Term Investments	Short-Term Investments Short-term investments have consisted of corporate notes, bonds, and commercial paper and U.S. government agency and government sponsored enterprise obligations. The Company accounts for these short-term investments as required by FASB ASC Topic No. 320, Investments-Debt and Equity Securities. These debt and equity securities are not classified as either held-to-maturity securities or trading securities. As such, they are classified as available-for-sale securities. Available-for-sale securities are recorded at fair value, with unrealized gains or losses recorded as a separate component of accumulated other comprehensive income in stockholders’ equity until realized.
Accounts Receivable and Allowance for Doubtful Accounts	Accounts Receivable and Allowance for Doubtful Accounts We sell our products worldwide. We perform ongoing credit evaluations of our customers and adjust credit limits based upon payment history, the customer’s current credit worthiness and various other factors, as determined by our review of their current credit information. We continuously monitor collections and payments from our customers. We estimate credit losses and maintain an allowance for doubtful accounts reserve based upon these estimates. While such credit losses have historically been within our estimated reserves, we cannot guarantee that we will continue to experience the same credit loss rates that we have in the past. If not, this could have an adverse effect on our consolidated financial statements. Allowances for product returns are included in other adjustments to accounts receivable on the accompanying consolidated balance sheets. Product returns are estimated based on historical experience and have also been within management’s estimates.
Inventories	Inventories Inventories consist principally of compact disks (“CDs”), boxes and manuals and are stated at the lower of cost (determined by the first-in, first-out method) or market. The Company regularly reviews its inventory quantities on hand and records a provision for excess and obsolete inventory based primarily on management’s forecast of product demand and production requirements. At December 31, 2016 and 2015, our net inventory of $12,000 and $39,000 respectively, consisted mostly of components.
Equipment and Improvements	Equipment and Improvements Equipment and improvements are stated at cost. Depreciation is computed using the straight-line method based on the estimated useful lives of the assets, generally ranging from three to seven years. Leasehold improvements are amortized using the straight-line method over the shorter of the estimated useful life of the asset or the lease term.
Internal Software Development Costs	Internal Software Development Costs Development costs incurred in the research and development of new software products and enhancements to existing software products are expensed as incurred until technological feasibility has been established. The Company considers technological feasibility to be established when all planning, designing, coding, and testing has been completed according to design specifications. After technological feasibility is established, any additional costs are capitalized. Through December 31, 2016, software has been substantially completed concurrently with the establishment of technological feasibility; accordingly, no costs have been capitalized to date.
Impairment or Disposal of Long-Lived Assets	Impairment or Disposal of Long Lived Assets Long-lived assets to be held are reviewed for events or changes in circumstances which indicate that their carrying value may not be recoverable. They are tested for recoverability using undiscounted cash flows to determine whether or not impairment to such value has occurred as required by FASB ASC Topic No. 360, Property, Plant, and Equipment
Goodwill	Goodwill In accordance with FASB ASC Topic No. 350, Intangibles-Goodwill and Other
Intangible Assets and Amortization	Intangible Assets and Amortization Amortization expense related to other intangibles acquired in acquisitions is calculated on a straight line basis over the useful lives.
Derivative Liabilities	Derivative Liabilities The Company analyzes all financial instruments with features of both liabilities and equity under FASB ASC Topic No. 480, Distinguishing Liabilities From Equity Derivatives and Hedging
Deferred Rent and Other Long-Term Liabilities	Deferred Rent and Other Long-Term Liabilities The long-term liabilities are for deferred rent to account for the difference between straight-line and bargain rents, lease incentives included in deferred rent, restructuring expenses, and sublease deposits.
Going Concern Evaluation	Going Concern Evaluation In connection with preparing consolidated financial statements for the year ended December 31, 2016, management evaluated whether there were conditions and events, considered in the aggregate, that raised substantial doubt about the Company’s ability to continue as a going concern within one year from the date that the financial statements are issued. The Company considered the following: • Operating losses for seven consecutive quarters. • Negative cash flow from operating activities for three consecutive quarters. • Depressed stock price resulting in being non-compliant with NASDAQ listing rules to maintain a stock price of $1.00/share resulting in the necessity to execute a 1:4 reverse stock split. • Loss of 32% of revenue from our number one customer, Sprint, in fiscal year 2016 versus fiscal year 2015. Ordinarily, conditions or events that raise substantial doubt about an entity’s ability to continue as a going concern relate to the entity’s ability to meet its obligations as they become due. The Company evaluated its ability to meet its obligations as they become due within one year from the date that the financial statements are issued by considering the following: • The Company raised $4.0 million of debt financing during the year ended December 31, 2016. • The Company has been able to raise capital from short-term loans from its Board members. • As a result of the Company’s restructuring that was implemented during the three months ended December 31, 2016, and again during the first quarter of fiscal 2017, the Company’s cost structure is now in line with its current baseline revenue projections. See Footnote 3 for additional details regarding restructuring. Management believes that the Company will generate enough cash from operations to satisfy its obligations for the next twelve months. The Company will take the following actions if it starts to trend unfavorable to its internal profitability and cash flow projections, in order to mitigate conditions or events that would raise substantial doubt about its ability to continue as a going concern: • Raise additional capital through short-term loans. • Implement additional restructuring and cost reductions. • Raise additional capital through a private placement. • Secure a commercial bank line of credit. • Dispose of one or more product lines. • Sell or license intellectual property.
Revenue Recognition	Revenue Recognition We currently report our net revenues under two operating groups: Wireless and Graphics. Within each of these groups, software revenue is recognized based on the customer and contract type. We recognize revenue when persuasive evidence of an arrangement exists, delivery has occurred, the price is fixed and determinable, and collectability is probable as required by FASB ASC Topic No. 605-985, Revenue Recognition-Software We have a few multiple element agreements for which we have contracted to provide a perpetual license for use of proprietary software, to provide non-recurring engineering, and in some cases, to provide software maintenance (post contract support). For these software and software-related multiple element arrangements, we must: (1) determine whether and when each element has been delivered; (2) determine whether undelivered products or services are essential to the functionality of the delivered products and services; (3) determine the fair value of each undelivered element using vendor-specific objective evidence (“VSOE”); and (4) allocate the total price among the various elements. VSOE of fair value is used to allocate a portion of the price to the undelivered elements and the residual method is used to allocate the remaining portion to the delivered elements. Absent VSOE, revenue is deferred until the earlier of the point at which VSOE of fair value exists for any undelivered element or until all elements of the arrangement have been delivered. However, if the only undelivered element is post contract support, the entire arrangement fee is recognized ratably over the performance period. We determine VSOE for each element based on historical stand-alone sales to third parties or from the stated renewal rate for the elements contained in the initial arrangement. In determining VSOE, we require that a substantial majority of the selling prices for a product or service fall within a reasonably narrow pricing range. We have established VSOE for our post contract support services and non-recurring engineering. On occasion, we enter into fixed fee arrangements, i.e. for trials, in which customer payments are tied to the achievement of specific milestones. Revenue for these contracts is recognized based on customer acceptance of certain milestones as they are achieved. We also enter hosting arrangements that sometimes include up-front, non-refundable set-up fees. Revenue is recognized for these fees over the term of the agreement. For Graphics sales, management reviews available retail channel information and makes a determination of a return provision for sales made to distributors and retailers based on current channel inventory levels and historical return patterns. Certain sales to distributors or retailers are made on a consignment basis. Revenue for consignment sales are not recognized until sell through to the final customer is established. Certain revenues are booked net of revenue sharing payments. Sales directly to end users are recognized upon shipment. End users have a thirty-day right of return, but such returns are reasonably estimable and have historically been immaterial. We also provide technical support to our customers. Such costs have historically been insignificant.
Sales Incentives	Sales Incentives For our Graphics sales, the cost of sales incentives the Company offers without charge to customers that can be used in, or that are exercisable by a customer as a result of, a single exchange transaction is accounted for as a reduction of revenue as required by FASB ASC Topic No. 605-50, Revenue Recognition-Customer Payments and Incentives
Advertising Expense	Advertising Expense Advertising costs are expensed as incurred. Advertising expenses were $0.5 million, $0.3 million, and $0.3 million for the years ended December 31, 2016, 2015, and 2014, respectively.
Stock-Based Compensation	Stock-Based Compensation The Company accounts for all stock-based payment awards made to employees and directors based on their fair values and recognized as compensation expense over the vesting period using the straight-line method over the requisite service period for each award as required by FASB ASC Topic No. 718, Compensation-Stock Compensation

Recently Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements In September 2015, FASB issued ASU No. 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments • An acquirer to recognize adjustments to provisional amounts identified during the measurement period in the reporting period in which the adjustment amounts are determined. • An acquirer to record, in the same period’s financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects resulting from the change to the provisional amounts. This effect is required to be calculated as if the accounting had been completed at the acquisition date. • An entity to present separately on the face of the income statement or disclose in the notes the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. The guidance was effective for financial statements issued for annual periods beginning after December 15, 2015, including interim periods within those fiscal years. The Company has adopted this standard and it did not have a material impact on the Company’s consolidated financial statements. In April 2015, FASB issued ASU No. 2015-03, Interest-Imputation of Interest (Topic 835-30): In August 2014, the FASB issued ASU No. 2014-15, Presentation of Financial Statements-Going Concern (Subtopic 205-40)

Substantial doubt about going concern, management's evaluation	In connection with preparing consolidated financial statements for the year ended December 31, 2016, management evaluated whether there were conditions and events, considered in the aggregate, that raised substantial doubt about the Company’s ability to continue as a going concern within one year from the date that the financial statements are issued. The Company considered the following:  Operating losses for seven consecutive quarters.  Negative cash flow from operating activities for three consecutive quarters.  Depressed stock price resulting in being non-compliant with NASDAQ listing rules to maintain a stock price of $1.00/share resulting in the necessity to execute a 1:4 reverse stock split.  Loss of 32% of revenue from our number one customer, Sprint, in fiscal year 2016 versus fiscal year 2015. Ordinarily, conditions or events that raise substantial doubt about an entity’s ability to continue as a going concern relate to the entity’s ability to meet its obligations as they become due. The Company evaluated its ability to meet its obligations as they become due within one year from the date that the financial statements are issued by considering the following:  The Company raised $4.0 million of debt financing during the year ended December 31, 2016.  The Company has been able to raise capital from short-term loans from its Board members.  As a result of the Company’s restructuring that was implemented during the three months ended December 31, 2016, and again during the first quarter of fiscal 2017, the Company’s cost structure is now in line with its current baseline revenue projections. See Footnote 3 for additional details regarding restructuring. Management believes that the Company will generate enough cash from operations to satisfy its obligations for the next twelve months.

Substantial doubt about going concern, management's plans, substantial doubt not alleviated	The Company will take the following actions if it starts to trend unfavorable to its internal profitability and cash flow projections, in order to mitigate conditions or events that would raise substantial doubt about its ability to continue as a going concern:  Raise additional capital through short-term loans.  Implement additional restructuring and cost reductions.  Raise additional capital through a private placement.  Secure a commercial bank line of credit.  Dispose of one or more product lines.  Sell or license intellectual property.
