Fair Value of Financial Instruments
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."
Convertible Note Embedded Derivative Liability and Warrant Liability
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
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.
Concentrations of Credit Risk
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.
