Subsequent Events [Abstract]
Subsequent Event	Subsequent EventOn September 22, 2016, the Company entered into an Agreement and Plan of Merger (the “Merger Agreement”) with WCI Communities, Inc. (“WCI”), under which the Company will acquire WCI through a merger for a combination of the Company’s Class A common stock and cash totaling $23.50 per share of WCI common stock. It is currently anticipated that the merger consideration payable to WCI stockholders will be $11.75 in cash and $11.75 in Class A common stock, with the Class A common stock valued at the average of its volume weighted average price on the New York Stock Exchange (“NYSE”) on each of the 10 NYSE trading days before closing. However, the Company has the right to reduce the portion of the merger consideration that will be Class A common stock and increase the portion that will be cash, including the right to make the entire merger consideration cash. The Merger Agreement provides that until October 26, 2016, WCI may actively solicit proposals from persons other than the Company. WCI can terminate the Merger Agreement to engage in a transaction that its Board of Directors deems to be more favorable to its stockholders than the transaction with the Company, unless the Company will match the deemed more favorable transaction. However, if WCI terminates the Merger Agreement to engage in another transaction, it will have to pay the Company a termination fee of $22.5 million, or $11.3 million if the more favorable transaction was proposed on or before October 26, 2016. The Merger Agreement contains customary representations and warranties by the parties, and is subject to closing conditions, including the need for approval by the holders of WCI’s common stock. It is anticipated that a meeting of WCI stockholders to vote on the transaction will be held in December 2016 or January 2017, and, if the transaction is approved by the WCI stockholders, it will close promptly after the stockholder vote.
