2. On March 5, 2012, the reporting person was awarded a maximum of 170,248 LTIP units, subject to certain performance conditions. On February 26, 2015, the Compensation Committee of the Board of Directors of the Company determined that the extent to which the performance measures had been achieved during the performance period resulted in 80.8%, or 137,555, of the LTIP units becoming earned LTIP units.
