Incentive Compensation	15. Incentive Compensation Our 2010 Omnibus Share Plan (the “Plan”) provides for grants of incentive and non-qualified stock options, restricted stock, restricted Operating Partnership units and out-performance plan awards to certain of our employees and officers. We account for all stock-based compensation in accordance with ASC 718, Compensation – Stock Compensation. Stock-based compensation expense was $11,024,000 and $7,466,000 in the three months ended March 31, 2014 and 2013, respectively. On January 10, 2014, the Compensation Committee approved the 2014 Outperformance Plan, a multi-year, performance-based equity compensation plan and related form of award agreement (the “2014 OPP”). Under the 2014 OPP, participants have the opportunity to earn compensation payable in the form of operating partnership units during a three-year performance measurement period, if and only if we outperform a predetermined total shareholder return (“TSR”) and/or outperform the market with respect to relative TSR. Awards under the 2014 OPP may be earned if we (i) achieve a TSR level greater than 7% per annum, or 21% over the three-year performance measurement period (the “Absolute Component”), and/or (ii) achieve a TSR above that of the SNL US REIT Index (the “Index”) over a three-year performance measurement period (the “Relative Component”). To the extent awards would be earned under the Absolute Component but we underperform the Index, such awards earned under the Absolute Component would be reduced (and potentially fully negated) based on the degree to which we underperform the Index. In certain circumstances, in the event we outperform the Index but awards would not otherwise be earned under the Absolute Component, awards may be increased under the Relative Component. To the extent awards would otherwise be earned under the Relative Component but we fail to achieve at least a 6% per annum absolute TSR, such awards earned under the Relative Component would be reduced based on our absolute TSR, with no awards being earned in the event our TSR during the applicable measurement period is 0% or negative, irrespective of the degree to which we may outperform the Index. If the designated performance objectives are achieved, OPP Units are also subject to time-based vesting requirements. Awards earned under the 2014 OPP vest 33% in year three, 33% in year four and 34% in year five. Dividends on awards earned accrue during the performance measurement period. In addition, our executive officers (for the purposes of Section 16 of the Exchange Act) are required to hold any earned OPP awards (or related equity) for at least one year following vesting.
