Payout comparison	Vesting of restricted stock awards is based on (1) the achievement of relative total shareholder return (“TSR”) and (2) the company and the personal performance of employees attributable to specific management business objectives. Approximately 50% of the restricted stock awards are based on the satisfaction of the TSR compared to (i) the NAREIT index, (ii) the Standards & Poor index, and (iii) a Selected Lodging Company index that serves as a relevant industry/asset specific measurement to our competitors, with the remaining 50% based on the achievement of management business objectives.

The shares withheld for employee tax requirements were valued at $5.5 million, $9.5 million and $15.4 million, for 2013, 2012 and 2011, respectively.
