Discretionary Incentive Compensation - Ms. Chen and Messrs. Brownback, Delbos, Garfin, Mehta, Rieder and Summers

Discretionary incentive compensation is a function of several components: the performance of BlackRock, Inc., the performance of the portfolio manager's group within BlackRock, the investment performance, including risk-adjusted returns, of the firm's assets under management or supervision by that portfolio manager relative to predetermined benchmarks, and the individual's performance and contribution to the overall performance of these portfolios and BlackRock. In most cases, these benchmarks are the same as the benchmark or benchmarks against which the performance of the Funds or other accounts managed by the portfolio managers are measured. Among other things, BlackRock's Chief Investment Officers make a subjective determination with respect to each portfolio manager's compensation based on the performance of the Funds and other accounts managed by each portfolio manager relative to the various benchmarks. Performance of fixed income funds is measured on a pre-tax and/or after-tax basis over various time periods including 1-, 3- and 5- year periods, as applicable. With respect to these portfolio managers, such benchmarks for the Funds and other accounts are:

 

Portfolio Manager	Benchmark
David Delbos Mitchell Garfin	A combination of market-based indices (e.g., The Bloomberg U.S. Corporate High Yield 2% Issuer Cap Index), certain customized indices and certain fund industry peer groups.
Russell Brownback1 Chi Chen Rick Rieder Sam Summers1	A combination of market-based indices (e.g., Bloomberg U.S. Aggregate Bond Index), certain customized indices and certain fund industry peer groups.
