(1) Reflects a 2015 BlackRock Performance Incentive Plan award value of $9,209,812 (converted to 26,784 Restricted Stock Units by dividing the award value by $343.855, which was the average of the high and low price per share of Common Stock on January 16, 2015). The award was disclosed in the table on page 35 of BlackRock's 2015 Proxy Statement in the column headed "Long-Term Incentive Award (BPIP)". As outlined in BlackRock's 2015 Proxy Statement, the award was subject to adjustment based on certain performance metrics approved by the Management Development and Compensation Committee at the time of the award. Based on the Company's performance, the Restricted Stock Units vesting represent 109.5% of original award.
(2) Includes Common Stock, Restricted Stock that will vest over a period of 1 to 3 years and Restricted Stock Units that will vest in whole or in part only on the satisfaction of one or more previously-disclosed Common Stock price targets. Restricted Stock and Restricted Stock Units are payable solely by delivery of an equal number of shares of Common Stock.
(3) Represents the withholding by BlackRock of common stock to satisfy tax obligation on the vesting of the reporting person's awards granted under the Second Amended and Restated BlackRock, Inc. 1999 Stock Award and Incentive Plan.
