All balances will be settled in cash. The swaps do not give ValueAct Master Fund, or any of the other Reporting Persons, direct or indirect voting, investment or dispositive control over any securities of the Issuer and do not require the counterparty thereto to acquire, hold, vote or dispose of any securities of the Issuer. Accordingly, the Reporting Persons disclaim any beneficial ownership of any Class A Shares that may be referenced in the swap agreements or Class A Shares or other securities or financial instruments that may be held from time to time by any counterparty to the agreements.
