Organization, Basis of Presentation and Summary of Significant Accounting Policies and Balance Sheet Details [Abstract] |
The Company | The Company Smith Micro Software, Inc. provides software and services that simplify, secure and enhance the mobile experience. The Company’s portfolio of wireless software products includes a wide range of client and server applications that manage voice and data communications and connectivity across 3G, 4G and Wi-Fi networks. We sell these products and services to many of the world’s leading mobile network operators, original equipment manufacturers (“OEM”), device manufacturers and enterprise businesses. The proliferation of mobile broadband technology is providing new opportunities for our products and services on a global basis. When broadband network technologies, such as EVDO, UMTS/HSPA, Wi-Fi, LTE and WiMAX, are combined with new mobile devices such as Smartphones, Tablet computers, Netbooks and emerging Machine-to-Machine (“M2M”) devices, many new challenges emerge in the areas of connectivity, reliability, security, performance, cost of ownership, and ease-of-use. Our core technologies are designed to address these emerging mobile challenges, helping our customers to save money while capitalizing on new revenue opportunities. Our products operate on a wide range of device platforms, including Windows, Mac, UNIX, Linux, iOS, Android, Windows Mobile, Symbian and Java platforms. Our patented compression technologies are utilized within various Smith Micro enterprise and consumer products, providing efficient data delivery and storage across a number of platforms. In addition to our wireless and mobility software, our innovative line of productivity and graphics products is distributed through a variety of consumer channels worldwide, our online stores, and third-party wholesalers, retailers and value-added resellers. The underlying philosophy common to all of our products is our desire to improve the user experience and optimize resources for our customers. These objectives are delivered through the combination of quality engineering, standards-based innovation, and unmatched software integration expertise. We have over 30 years of experience in the design, engineering, and commercial deployment of mobile software products around the world.
Basis of Presentation | Basis of Presentation The accompanying consolidated financial statements reflect the operating results and financial position of Smith Micro Software, Inc. 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 | Foreign Currency Transactions The Company has international operations resulting from acquisitions over the past several years. The countries in which the Company has a subsidiary or branch office in are Hong Kong, Serbia, 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. Foreign currency transactions that increase or decrease expected functional currency cash flows is a foreign currency transaction gain or loss that are included in determining net income for the period in which the exchange rate changes. Likewise, a transaction gain or loss (measured from the transaction date or the most recent intervening balance sheet date, whichever is later) realized upon settlement of a foreign currency transaction is included in determining net income for the period in which the transaction is settled.
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. The carrying value of accounts receivable, foreign cash accounts, prepaid expenses, other current assets, accounts payable, and accrued liabilities are considered to be representative of their respective fair values because of the short-term nature of those instruments. 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, an entity can choose to measure at fair value many financial instruments and certain other items that are not currently required to be measured at fair value. Subsequent changes in fair value for designated items are required to be reported in earnings in the current period. This Topic also establishes presentation and disclosure requirements for similar types of assets and liabilities measured at fair value. As permitted, the Company has elected not to use the fair value option to measure our available-for-sale securities under this Topic and will continue to report as required by FASB ASC Topic No. 320, Investments-Debt and Equity Securities. We have made this election because the nature of our financial assets and liabilities are not of such complexity that they would benefit from a change in valuation to fair value.
Significant Concentrations | Significant Concentrations For the year ended December 31, 2012, two customers, each accounting for over 10% of revenues, made up 61.2% of revenues and 78% of accounts receivable, and three suppliers, each with more than 10% of inventory purchases, totaled 1% of accounts payable. For the year ended December 31, 2011, three customers, each accounting for over 10% of revenues, made up 54.9% of revenues and 63% of accounts receivable, and four suppliers, each with more than 10% of inventory purchases, totaled 4% of accounts payable. For the year ended December 31, 2010, three customers, each accounting for over 10% of revenues, made up 66.3% of revenues and 78% of accounts receivable, and five suppliers, each with more than 10% of inventory purchases, totaled 5% 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 (“FDIC”) coverage, and have original maturity dates of three months or less. As of December 31, 2012 and 2011, bank balances totaling approximately $9.1 million and $3.3 million, respectively, were uninsured. As of January 1, 2013, the Dodd-Frank Deposit Insurance Provision which provided insurance on substantially all deposits held in non-interest bearing transaction accounts, expired. Had this provision expired at year-end, our uninsured bank balance would have been approximately $18.6 million at December 31, 2012.
Short-Term Investments | Short-Term Investments Short-term investments consist 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, 2012, our net inventory balance of $0.2 million consisted of $0.1 million of assembled products and $0.1 million of components. At December 31, 2011, our net inventory balance of $0.3 million consisted of $0.2 million of assembled products and $0.1 million 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, 2012, software has been substantially completed concurrently with the establishment of technological feasibility; accordingly, no costs have been capitalized to date.
Impairment of Goodwill and Long Lived Assets | Impairment of Goodwill and Long-Lived Assets During the period ended September 30, 2011, the Company concluded that a decline in its stock price and market capitalization was representative of the fair value of the reporting unit as a whole. The triggering events that led us to this conclusion were:
| • |  | Revenues - declined for the third consecutive quarter.
| • |  | New product launches - although we were in trials for several of our new products, as of September 30, 2011 we had not realized any revenues from these new products.
| • |  | Profitability - declined for the third consecutive quarter.
| • |  | Stock price - remained at depressed prices.
As such, the Company performed Step 1 of the goodwill impairment test which failed, triggering Step 2. As a result of this analysis, the excess of the carrying value of goodwill was compared to the implied fair value of goodwill and resulted in an impairment loss of $94.2 million in the fiscal quarter ended September 30, 2011. As a result of the triggering events described above in our goodwill impairment analysis, the Company reviewed its long-lived assets for recoverability. As a result of this analysis, the Company recognized a long-lived asset impairment charge of $18.7 million in the fiscal quarter ended September 30, 2011 which was allocated pro-rata to the intangible assets of $13.4 million and $5.3 million to equipment and improvements, primarily related to our leasehold improvements. As a result of the $112.9 million goodwill and long-lived asset impairment charge recorded in the fiscal quarter ended September 30, 2011, there were no more goodwill or intangible assets on the balance sheet as of that date.
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, the Pennsylvania Opportunity Grant liability and deferred revenue beyond one year.
Revenue Recognition | Revenue Recognition We currently report our net revenues under two operating groups: Wireless and Productivity & 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. 985-605, Software-Revenue Recognition. We recognize revenues from sales of our software to our customers or end users as completed products are shipped and title passes; or from royalties generated as authorized customers duplicate our software, if the other requirements are met. If the requirements are not met at the date of shipment, revenue is not recognized until these elements are known or resolved. For Wireless sales, returns from customers are limited to defective goods or goods shipped in error. Historically, customer returns have not exceeded the very nominal estimates and reserves. We also provide some technical support to our customers. Such costs have historically been insignificant. 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. For Productivity & 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 Productivity & 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. 985-605, Software-Revenue Recognition. We use historical redemption rates to estimate the cost of customer incentives. Total sales incentives were $0.9 million, $1.2 million and $2.0 million for the years ended December 31, 2012, 2011 and 2010, respectively.
Advertising Expense | Advertising Expense Advertising costs are expensed as incurred. Advertising expenses were $0.6 million, $0.7 million, and $0.9 million for the years ended December 31, 2012, 2011 and 2010, 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.
Recent Accounting Pronouncements | Recent Accounting Pronouncements In December 2011, the FASB issued Accounting Standards Update (“ASU”) No. 2011-12, Comprehensive Income (Topic 220). The amendments in this Update supersede certain pending paragraphs in ASU No. 2011-05, Comprehensive Income (Topic 220): Presentation of Comprehensive Income, to effectively defer only those changes in Update 2011-05 that relate to the presentation of reclassification adjustments out of accumulated other comprehensive income. The amendments will be temporary to allow the Board time to redeliberate the presentation requirements for reclassifications out of accumulated other comprehensive income for annual and interim financial statements for public, private, and non-profit entities. In June 2011, the FASB issued ASU No. 2011-05, Comprehensive Income (Topic 220): Presentation of Comprehensive Income. Under the amendments to this Update, an entity has the option to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. The Company has implemented this guidance. In May 2011, the FASB issued ASU No. 2011-04, Fair Value Measurements and Disclosures (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs. The amendments in this Update result in common fair value measurement and disclosure requirements in U.S. GAAP and IFRSs. Consequently, the amendments change the wording used to describe many of the requirements in U.S. GAAP for measuring fair value and for disclosing information about fair value measurements. The Company has implemented this guidance and its adoption has not had an impact on its consolidated results of operations and financial condition.
Net Income (Loss) Per Share | Net Income (Loss) Per Share The Company calculates earnings per share (“EPS”) as required by FASB ASC Topic No. 260, Earning Per Share. Basic EPS is calculated by dividing the net income available to common stockholders by the weighted average number of common shares outstanding for the period, excluding common stock equivalents. Diluted EPS is computed by dividing the net income available to common stockholders by the weighted average number of common shares outstanding for the period plus the weighted average number of dilutive common stock equivalents outstanding for the period determined using the treasury-stock method. For purposes of this calculation, common stock subject to repurchase by the Company and options are considered to be common stock equivalents and are only included in the calculation of diluted earnings per share when their effect is dilutive.
Income Taxes | We account for income taxes as required FASB ASC Topic No. 740, Income Taxes. This Topic clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements and prescribes a recognition threshold and measurement process for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. The Topic also provides guidance on de-recognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. The Topic requires an entity to recognize the financial statement impact of a tax position when it is more likely than not that the position will be sustained upon examination. The amount recognized is measured as the largest amount of benefit that is greater than fifty percent likely of being realized upon ultimate settlement. In addition, the Topic permits an entity to recognize interest and penalties related to tax uncertainties either as income tax expense or operating expenses. The Company has chosen to recognize interest and penalties related to tax uncertainties as operating expense. In 2007, the Company adopted FASB ASC Topic 740, “Income Taxes,” which clarifies the accounting for income taxes by prescribing a minimum recognition threshold that a tax position is required to meet before being recognized in the financial statements. Management determined based on its evaluation of the Company’s income tax positions that it has uncertain tax positions relating to research and development (“R&D”) tax credits of $0.6 million at December 31, 2012 and $0.3 million at December 31, 2011 for which the Company has not yet recognized an income tax benefit for financial reporting purposes. Assuming these tax benefits had been recognized as of December 31, 2012, such benefit would have been fully negated by a corresponding increase in the deferred income tax valuation allowance because the Company has recorded a full valuation allowance against its recognized R&D tax credits of $3.0 million due to uncertainty as to future realization.
Segment Reporting | Segment Information Public companies are required to report financial and descriptive information about their reportable operating segments as required by FASB ASC Topic No. 280, Segment Reporting. The Company has two primary business units based on how management internally evaluates separate financial information, business activities and management responsibility. Wireless includes our QuickLink, NetWise and CommSuite family of products. Productivity & Graphics includes our consumer-based products: Poser, Anime Studio, Manga Studio, MotionArtist and StuffIt. “Corporate/Other” revenue includes the consulting portion of our services sector which has been de-emphasized and is not a strategic element of our future plans.
Subsequent Events | In May 2009, the FASB issued new accounting guidance found under ASC Topic No. 855, Subsequent Events. The Topic establishes general standards of accounting for and disclosure of events that occur after the balance sheet date but before the financial statements are issued or are available to be issued Subsequent events have been evaluated as of the date of this filing and there are no further disclosures required.
