2. Immediately prior to the completion of the Company's initial public offering, the Company effected a 262.8376-for-1 stock split of its outstanding Class B common and, pursuant to the Amended and Restated Limited Liability Company Agreement of TerraForm Power, LLC ("Terra LLC") dated as of July 23, 2014 and a related exchange agreement dated as of July 23, 2013 (the "Exchange Agreement"), SunEdison Holdings' existing ownership interest in Terra LLC was reclassified into a number of Class B units of equal to the number of shares of Class B common stock held by SunEdison Holdings following such stock split.

3. Represents shares of Class B common stock of the Company and Class B units of Terra LLC received by SunEdison Holdings pursuant to a pro rata distribution of securities by Silver Ridge Power LLC ("Silver Ridge") on account of SunEdison Holdings' existing ownership interest in Silver Ridge.

The Class B units of Terra LLC (together with a corresponding number of shares of Class B common stock of the Company) are exchangeable at any time for shares of Class A common stock of the Company on a one-for-one basis, subject to equitable adjustments for stock splits, stock dividends and reclassifications. As SunEdison Holdings exchanges the Class B units for shares of Class A common stock pursuant to the Exchange Agreement, an equivalent number of shares of Class B common stock issued to SunEdison Holdings will automatically be cancelled.

5. Represents Class B units of Terra LLC (and a corresponding number of shares of Class B common stock) acquired by the Company from SunEdison Holdings.
