The investment objective of BlackRock Mid-Cap Growth Equity Portfolio ( Mid-Cap Growth Equity or the Fund), a series of BlackRock Funds SM (the Trust ), is long-term capital appreciation.
The fund invests at least 80% of its net assets in common and preferred stock of U.S. mid-capitalization companies—those with market capitalizations in the range of the Russell Midcap Growth Index—that are also included in at least one major growth index as determined by BlackRock. The fund may also use derivatives, primarily to hedge risk, and may invest in convertible securities and IPOs. Because the fund's selection depends on inclusion in growth indices as BlackRock determines them, holdings may diverge from any single benchmark.

| 0.71% | +10.64% | +45.56% | +9.54% | -18.69% |
These classes hold the same portfolio, so the 5.77pp spread over 5 years is the cost difference between them — roughly 1.15pp a year — not a difference in what they own.
