Item 6.	Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer.
	The responses to Items 3, 4 and 5 of this Schedule 13D are hereby incorporated by reference.
	The Reporting Persons have purchased and sold American-style and European-style call and put options. The Reporting Persons: (i) own American-style call options referencing an aggregate of 1,731,622 Shares, which have an exercise price of $30.00 per Share and expire on July 18, 2014 and (ii) have sold European-style put options referencing an aggregate of 1,731,622 Shares, which have an exercise price of $30.00 per Share and expire on July 18, 2014.

Certain of the Reporting Persons have entered into swaps with respect to the Shares. Under the terms of the swaps, (i) the relevant Reporting Persons will be obligated to pay to the counterparty any negative price performance of the specified notional number of Shares subject to the swaps as of the expiration date of such swaps, plus interest rates set forth in the applicable contracts, and (ii) the counterparty will be obligated to pay the relevant Reporting Persons any positive price performance of the specified notional number of Shares subject to the swaps as of the expiration date of the swaps. The counterparties will also be required to pay the Reporting Persons the value of any dividends paid on such notional Shares during the term of the swaps.  All balances will be settled in cash. The Reporting Persons’ counterparty for the swap is Morgan Stanley Capital Services LLC.  The swaps do not give the 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 Shares that may be referenced in the swap contracts or Shares or other securities or financial instruments that may be held from time to time by any counterparty to the contracts.
