Restricted Stock Awards
RSAs provide the holder with immediate voting rights, but are restricted in all other respects until vested. Upon a termination of employment for any reason, any unvested shares of Class A common stock held by the terminated participant will be forfeited. All unvested RSAs are paid dividends and distributions.
The following table presents information regarding outstanding RSAs as of December 31, 2015 and changes during the year then ended, after giving effect to the conversion of restricted Class C common stock to restricted Class A common stock on a 178.8491-for-one basis:
Number of RSAs Outstanding
Weighted Average Grant Date Fair Value Per Share
Aggregate Intrinsic Value
Balance at January 1, 2015
Balance at December 31, 2015
As of December 31, 2015, $1.1 million of total unrecognized compensation cost related to RSAs is expected to be recognized over a weighted average period of approximately 3.3 years.
The weighted average fair value of RSAs on the date of grant was $0.21 and $0.12 for the years ended December 31, 2015 and 2014, respectively.
On September 26, 2014 and March 31, 2015, the Company granted 31,350 and 35,245 shares of restricted Class C common stock, respectively (or 5,606,918 and 6,303,519 shares, respectively, of restricted Class A common stock after giving effect to conversion of restricted Class C common stock to restricted Class A common stock on an 178.8491-for-one basis immediately prior to the completion of the IPO). Subject to accelerated vesting upon certain events, 25.0% of the restricted Class A common stock will vest on the first through fourth anniversary of the date of the IPO. The fair value of each grant was determined by using the percentage of shares granted multiplied by the overall fair value of SunEdison’s equity in the Company. In estimating the fair value of the RSAs, the primary valuation considerations were an enterprise value determined from a discounted cash flow of income-based approach, using a present value of after-tax probability weighted equity cash flow of those power plants expected to be included in the IPO, in a projection period extending through December 2024 and a lack of marketability discount of 10.0% and 5.0% for the September 26, 2014 and March 31, 2015 grants, respectively. The discount model used the following assumptions: a time to liquidity event of seven months and three months; a discount rate of 13.0% and 12.0%; and volatility of 40.0% over the time to a liquidity event for the September 26, 2014 and March 31, 2015 grants, respectively. Estimates of the volatility of the Company’s Class A common stock were based on available information on the volatility of SunEdison and the common stock of comparable publicly traded companies.
The removal of our prior Chief Executive Officer and Chief Financial Officer on November 20, 2015 resulted in the forfeiture of 1,877,915 shares of restricted Class A common stock. The impact of these forfeitures on our stock-based compensation expense for the year ended December 31, 2015 was not material.
