Summary of Significant Accounting Policies
Summary of Significant Accounting Policies
The significant accounting policies and recent accounting pronouncements were described in Note 4 of the consolidated financial statements included in the Annual Report on Form 10-K for the fiscal year ended March 31, 2016. There have been no significant changes in or updates to the accounting policies since March 31, 2016, except as noted below.
Restricted Cash
Cash accounts that are restricted to withdrawal or usage are presented as restricted cash. As of September 30, 2016 and March 31, 2016, the Company had $321 and $0, respectively, of restricted cash held by a bank in a collateral account as collateral to cover the Company's corporate credit cards as well as a letter of credit issued to guarantee a facility lease.
Debt Issuance Costs
In April 2015, the FASB issued accounting guidance which requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability under ASU 2015-03. The guidance is effective for fiscal years beginning after December 15, 2015, including interim periods within those fiscal years; as such, the Company adopted this guidance in the quarter ended June 30, 2016. The Company has determined that adopting ASU 2015-03 did not have a significant impact on its consolidated results of operations, financial condition, and cash flows. Refer to Note 7 Debt for more details.
Stock Compensation
In March 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Codification ASU 2016-09 “Stock Compensation - Improvements to Employee Share-Based Payment Accounting” which simplifies several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The amendment is effective for the Company for fiscal years, and interim periods within those years, beginning after December 15, 2016. Early adoption is permitted. If an entity early adopts the amendments in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. An entity that elects early adoption must adopt all of the amendments in the same period.
ASU 2016-09 requires the following:
Accounting for Income Taxes: All excess tax benefits and tax deficiencies (including tax benefits of dividends on share-based payment awards) should be recognized as income tax expense or benefit in the income statement. The tax effects of exercised or vested awards should be treated as discrete items in the reporting period in which they occur. An entity also should recognize excess tax benefits regardless of whether the benefit reduces taxes payable in the current period.
Classification of Excess Tax Benefits on the Statement of Cash Flows: Excess tax benefits should be classified along with other income tax cash flows as an operating activity.
Forfeitures: An entity can make an entity-wide accounting policy election to either estimate the number of awards that are expected to vest (current GAAP) or account for forfeitures when they occur.
Minimum Statutory Tax Withholding Requirements: The threshold to qualify for equity classification permits withholding up to the maximum statutory tax rates in the applicable jurisdictions.
Classification of Employee Taxes Paid on the Statement of Cash Flows When an Employer Withholds Shares for Tax-Withholding Purposes: Cash paid by an employer when directly withholding shares for taxwithholding purposes should be classified as a financing activity.
Practical Expedient—Expected Term: A nonpublic entity can make an accounting policy election to apply a practical expedient to estimate the expected term for all awards with performance or service conditions that meet certain conditions.
Intrinsic Value: A nonpublic entity can make a one-time accounting policy election to switch from measuring all liability-classified awards at fair value to intrinsic value.
The Company is evaluating the impact of the adoption on the consolidated financial statements.
Fair Value of Financial Instruments
The Company measures certain financial assets and liabilities at fair value based on the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants. Where available, fair value is based on or derived from observable market prices or other observable inputs. Where observable prices or inputs are not available, valuation techniques are applied. These valuation techniques involve some level of management estimation and judgment, the degree of which is dependent on the price transparency for the instruments or market and the instruments’ complexity.
The carrying amounts of certain financial instruments, such as cash equivalents, short term investments, accounts receivable, accounts payable and accrued liabilities, approximate fair value due to their relatively short maturities. The fair value of the convertible notes issued on September 28, 2016 is determined using the residual method of accounting where-by the portion of the proceeds so allocated to the embedded derivatives and warrants issued is accounted for as a derivative liability and warrant liability, respectively, and the remainder of the proceeds is allocated to the convertible notes, resulting in debt discount. The convertible notes are carried on the consolidated balance sheet on a historical cost basis, net of discounts and debt issuance costs.
The Company estimates the fair value of the embedded derivatives for the convertible notes and warrant liability using a lattice approach that incorporates a Monte Carlo simulation valuation model that considers the Company's future stock price, stock price volatility, probability of a change of control and the trading information of the Company's common stock into which the notes are or may become convertible.
Changes in the inputs into these valuation models have a significant impact on the estimated fair value of the embedded derivatives. For example, a decrease (increase) in the stock price results in a decrease (increase) in the estimated fair value of the embedded derivatives. The change in the fair value of the bifurcated embedded derivatives and warrant liability are primarily related to the change in price of the Company's underlying common stock and are reflected in the consolidated statements of operations and comprehensive loss as "Change in fair value of convertible note embedded derivative liability” and "Change in fair value of warrant liability." Refer to Note 8 "Fair Value Measurements" for more details.
Convertible Note Embedded Derivative Liability
Embedded derivatives that are required to be bifurcated from the underlying debt instrument (i.e. host) are accounted for and valued as a separate financial instrument. We evaluated the terms and features of our convertible notes issued on September 28, 2016 and identified embedded derivatives (conversion options that contain “make-whole interest” provisions, fundamental change provisions, or down round conversion price adjustment provisions) requiring bifurcation and accounting at fair value because the economic and contractual characteristics of the embedded derivatives met the criteria for bifurcation and separate accounting. ASC 815-10-15-83 (c) states that if terms implicitly or explicitly require or permit net settlement, it can readily be settled net by means outside the contract, or it provides for delivery of an asset that puts the recipient in a position not substantially different from net settlement. The conversion features related to the convertible notes consists of a “make-whole interest” provision, fundamental change provision, and down round conversion price adjustment provisions, which if the convertible notes were to be converted, would put the convertible note holder in a position not substantially different from net settlement. Given this fact pattern, the conversion features meet the definition of embedded derivatives and require bifurcation and accounting at fair value.
See Note 8, "Fair Value Measurements" of this report for a description of our embedded derivatives related to the convertible notes and information on the valuation model used to calculate the fair value of the embedded derivatives. Changes in the inputs into the valuation model may have a significant impact on the estimated fair value of the embedded derivatives. For example, a decrease (increase) in the stock price results in a decrease (increase) in the estimated fair value of the embedded derivatives. The changes in the fair value of the bifurcated embedded derivatives are primarily related to the change in price of the underlying common stock of the Company and is reflected in our consolidated statements of operations as “Change in fair value of convertible note embedded derivative liability.”
Warrant Liability 
The Company issued detachable warrants with the convertible notes issued on September 28, 2016. The Company accounts for its warrants issued in accordance with US GAAP accounting guidance under ASC 815 applicable to derivative instruments, which requires every derivative instrument within its scope to be recorded on the balance sheet as either an asset or liability measured at its fair value, with changes in fair value recognized in earnings. Based on this guidance, the Company determined that these warrants did not meet the criteria for classification as equity. Accordingly, the Company classified the warrants as long-term liabilities. The warrants are subject to re-measurement at each balance sheet date, with any change in fair value recognized as a component of other income (expense), net in the statements of operations. We estimated the fair value of these warrants at the respective balance sheet dates using a lattice approach that incorporates a Monte Carlo simulation that considers the Company's future stock price. Option pricing models employ subjective factors to estimate warrant liability; and, therefore, the assumptions used in the model are judgmental.
See Note 8, "Fair Value Measurements" of this report for a description of our warrant liability and information on the valuation model used to calculate the fair value of the warrant liability. Changes in the inputs into the valuation model may have a significant impact on the estimated fair value of the warrant liability. For example, a decrease (increase) in the stock price results in a decrease (increase) in the estimated fair value of the warrant liability. The change in the fair value of the warrant liability is primarily related to the change in price of the underlying common stock of the Company and is reflected in our consolidated statements of operations as “Change in fair value of warrant liability.”
Principles of Consolidation
The consolidated financial statements include the accounts of the Company and our wholly-owned subsidiaries. All material inter-company balances and transactions have been eliminated in consolidation.
Interim Consolidated Financial Information
The accompanying consolidated financial statements of Digital Turbine, Inc. should be read in conjunction with the consolidated financial statements and accompanying notes filed with the U.S. Securities and Exchange Commission ("SEC") in Digital Turbine, Inc.'s Annual Report on Form 10-K for the fiscal year ended March 31, 2016, as amended. The accompanying consolidated financial statements have been prepared in accordance with U.S. GAAP and pursuant to the rules and regulations of the SEC. Certain information and footnote disclosures normally included in financial statements prepared in accordance with US GAAP have been condensed or omitted pursuant to such rules and regulations. In the opinion of management, the accompanying consolidated financial statements reflect all adjustments of a normal recurring nature considered necessary to fairly state the financial position of Digital Turbine, Inc. and its consolidated subsidiaries at September 30, 2016, the results of its operations and corresponding comprehensive loss, and its cash flows for the three and six months ended September 30, 2016 and 2015. The results of operations for the interim period are not necessarily indicative of the results that may be expected for the year ending March 31, 2017.
Concentrations of Credit Risk
Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash and accounts receivable. A significant portion of the Company’s cash is held at one major financial institution that the Company's management has assessed to be of high credit quality. The Company has not experienced any losses in such accounts.
The Company mitigates its credit risk with respect to accounts receivable by performing credit evaluations and monitoring advertisers' and carriers' accounts receivable balances. As of September 30, 2016, one major Content customer represented approximately 10.3% of the Company’s net accounts receivable balance and one major Advertising customer represented approximately 21.1% of the Company’s net accounts receivable balance. As of March 31, 2016, the previously mentioned major Content customer represented 15.6% of the Company’s net accounts receivable balance and the previously mentioned major Advertising customer represented 5.5% of the Company's net accounts receivable balance.
With respect to revenue concentration, the Company defines a customer as an advertiser or a carrier that is a distinct source of revenue and is legally bound to pay for the services that the Company delivers on the advertiser’s or carrier's behalf. The Company counts all advertisers and carriers within a single corporate structure as one customer, even in cases where multiple brands, branches, or divisions of an organization enter into separate contracts with the Company. During the three and six months ended September 30, 2016, the previously mentioned major Content customer represented 21.3% and 27.3%, respectively, of net revenues, the previously mentioned major Advertising customer represented 16.7% and 12.1%, respectively, of net revenues, and another major Advertising customer represented 13.7% and 10.2%, respectively, of net revenues. During the three and six months ended September 30, 2015, the previously mentioned major Content customer represented 29.2% and 29.4%, respectively, of net revenues, the previously mentioned major Advertising customer represented 0.4% and 1.5%, respectively, of net revenues, and the previously mentioned second major Advertising customer represented 8.0% and 8.3%, respectively, of net revenues.
