[1] Pursuant to an employment agreement (the “Employment Agreement”) executed in April 2008, the Chief Executive Officer (“CEO”) is eligible to receive an award amount equal to 8% of any proceeds from distributions or other liquidity events in excess of the return of the Company’s aggregate investment in TV One. The Company reviews the factors underlying this award at the end of each quarter including the valuation of TV One and an assessment of the probability that the employment agreement will be renewed and contain this provision. The Company’s obligation to pay the award will be triggered only after the Company’s recovery of the aggregate amount of its capital contribution in TV One and only upon actual receipt of distributions of cash or marketable securities or proceeds from a liquidity event with respect to the Company’s membership interest in TV One. The CEO was fully vested in the award upon execution of the Employment Agreement, and the award lapses if the CEO voluntarily leaves the Company or is terminated for cause. In estimating the fair value of the award, the Company determined that there was no change in TV One’s enterprise fair value since the December 31, 2012 valuation (See Note 6 – Derivative Instruments and Hedging Activities.) The terms of the April 2008 employment agreement remain in effect including eligibility for the TV One award.
