        <footnote id="F1">A portion of the shares of the series of Class A common stock held by the Reporting Person automatically converted into shares of Class P common stock on a one-for-one basis upon the conversion of a separate series of Class A common stock held by third parties into shares of Class P common stock. The shares of Class A common stock initially are convertible into shares of Class P common stock on a one-for-one basis, and shares of the issuer's Class B common stock and Class C common stock initially are not convertible into any shares of Class P common stock. Upon certain circumstances, shares of the issuer's Class B common stock and Class C common stock may convert into shares of Class P common stock, and the shares of Class A common stock would become convertible into a correspondingly lesser number of shares of Class P common stock. Any shares of Class A common stock outstanding on May 31, 2015 will automatically convert into shares of Class P common stock.</footnote>
