(1) On January 31, 2007, the reporting person received a 4 year and 8 month long-term award of 5,335 Restricted Stock Units, subject to the achievement of a performance goal and with a vesting date of September 29, 2011. Although the performance goal was met in 2009, the Restricted Stock Units will not vest until September 29, 2011 and remain subject to other conditions until that time. The number of Restricted Stock Units was determined by dividing the approved dollar value of the equity award by $168.66, which was the 5-day average closing price for January 25, 26, 29, 30 and 31, 2007. The Restricted Stock Units were granted under BlackRock, Inc.'s long-term incentive program which is designed to aid in the retention of senior management and align their interests with long-term shareholder interests.
(2) Includes (i) 199 Restricted Stock Units vesting on 1/31/11, (ii) 602 Restricted Stock Units vesting in equal installments on 1/31/11 and 1/31/12, (iii) 485 Restricted Stock Units vesting in installments on 1/31/11, 1/31/12 and 1/31/13, (iv) 1,942 Restricted Stock Units vesting on 1/31/12 and (v) 5,335 Restricted Stock Units vesting on 9/29/11.
