[2] | In connection with the Employee Matters Agreement with Time Warner Inc. ("Time Warner"), we are required to indemnify Time Warner for international equity awards in connection with our employees' exercises of stock compensation awards granted by Time Warner. The fair value of this obligation, as included within Accounts payable and accrued liabilities and Other noncurrent liabilities on the accompanying Balance Sheets was derived using a Black-Scholes model and is considered a Level 3 measurement. Adjustments to fair value of this obligation are included as a component of Other expense, net in the Statements of Operations. | |
[3] | Contingent consideration, of which $1 million is included in Accounts payable and accrued liabilities and $4 million in Other noncurrent liabilities on the accompanying Balance Sheets, consists of earnout liabilities in connection with acquisitions made during the first half of 2015. The fair value was derived using a probability weighted present value of expected future payouts approach, which is considered a Level 3 measurement. Adjustments to fair value of such obligations are included as a component of Selling, general and administrative expenses in the Statements of Operations. Such contingent consideration is primarily based on financial targets and other metrics. | |
[4] | Our other liabilities included within Other noncurrent liabilities on the accompanying Balance Sheets consist primarily of a put option liability related to an equity method investment, the fair value of which was derived using a lattice model which is considered a Level 3 measurement. Adjustments to fair value of this obligation are included as a component of Other expense, net in the Statements of Operations. | |
[5] | Consists of investments related to deferred compensation. The fair value of equity securities is determined based on quoted market prices at the end of the reporting period. The fair value of debt securities is determined based on net asset values at the end of the reporting period. | |
