Summary of Significant Accounting Policies
Significant accounting policies are described in Note 2 to the consolidated financial statements in Item 15 of the Company’s Annual Report on Form 10-K for the year ended December 31, 2014. There have been no changes to the Company’s significant accounting policies during the three and nine months ended September 30, 2015, except as described below.
Use of Estimates The preparation of consolidated financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the amounts reported in the Condensed Consolidated Financial Statements and accompanying notes. Such management estimates include the fair value of common stock, stock-based compensation, fair value of convertible preferred stock and warrants, fair value of derivatives, and the valuation of deferred tax assets. The Company bases its estimates on historical experience and also on assumptions that it believes are reasonable, however, actual results could significantly differ from those estimates. Cash and Cash Equivalents The Company considers all highly liquid investment securities with original maturities at the date of purchase of three months or less to be cash equivalents. Cash and cash equivalents may include cash on deposit, money market funds, and debt securities. Investments Short-term investments generally consist of securities with original maturities greater than three months and remaining maturities of less than one year, while long-term investments generally consist of securities with remaining maturities greater than one year. The Company determines the appropriate classification of its investments at the time of purchase and reevaluates such determination at each balance sheet date. All of its investments are classified as available-for-sale and carried at fair value, with the change in unrealized gains and losses reported as a separate component of other comprehensive income (loss) on the Condensed Consolidated Statements of Operations and Comprehensive Loss and accumulated as a separate component of stockholders' equity on the Condensed Consolidated Balance Sheets. Interest income, net includes interest, dividends, amortization of purchase premiums and discounts, realized gains and losses on sales of securities and other-than-temporary declines in the fair value of investments, if any. The cost of securities sold is based on the specific-identification method. The Company monitors its investment portfolio for potential impairment on a quarterly basis. If the carrying amount of an investment in debt securities exceeds its fair value and the decline in value is determined to be other-than-temporary, the carrying amount of the security is reduced to fair value and a loss is recognized in operating results for the amount of such decline. In order to determine whether a decline in value is other-than-temporary, the Company evaluates, among other factors, the cause of the impairment, including the creditworthiness of the security issuers, the number of securities in an unrealized loss position, the severity and duration of the unrealized losses, and its intent and ability to hold the security to maturity or forecasted recovery. The Company mitigates its credit risk by investing in money market funds and U.S. government agency obligations which limits the amount of investment exposure as to credit quality and maturity. Fair Value of Financial Instruments The Company uses fair value measurements to record fair value adjustments to certain financial and non-financial assets and liabilities to determine fair value disclosures. The accounting standards define fair value, establish a framework for measuring fair value, and require disclosures about fair value measurements. Fair value is defined as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required to be recorded at fair value, the principal or most advantageous market in which the Company would transact are considered along with assumptions that market participants would use when pricing the asset or liability, such as inherent risk, transfer restrictions, and risk of nonperformance. The accounting standard for fair value establishes a fair value hierarchy based on three levels of inputs, the first two of which are considered observable and the last unobservable, that requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. A financial instrument’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The three levels of inputs that may be used to measure fair value are as follows: | | | | | | Level 1 | — | Observable inputs, such as quoted prices in active markets for identical assets or liabilities. | | | | | | Level 2 | — | Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. | | | | | | Level 3 | — | Valuations based on unobservable inputs to the valuation methodology and including data about assumptions market participants would use in pricing the asset or liability based on the best information available under the circumstances. |
Accounting Pronouncements In August 2014, the FASB issued Accounting Standard Update No. 2014-15, Presentation of Financial Statements - Going Concern (Subtopic 205-40), which will require management to assess an entity’s ability to continue as a going concern at each annual and interim period. Related footnote disclosures will be required if conditions give rise to substantial doubt about an entity’s ability to continue as a going concern within one year of the report issuance date. If conditions do not give rise to substantial doubt, no disclosures will be required specific to going concern uncertainties. The guidance defines substantial doubt using a likelihood threshold of “probable” similar to the current use of that term in U.S. GAAP for loss contingencies and provides example indicators. The guidance is effective for reporting periods ending after December 15, 2016, and early adoption is permitted. The Company is currently evaluating the impact of the adoption of this guidance on the Company’s financial statements. |
