The Underlying Index represents approximately 85% of the free float-adjusted market capitalization in the U.S. The Underlying Index is free float-adjusted market capitalization weighted.

  3.   The last paragraph of the Principal Investment Strategies section in the Fund’s Summary Prospectus and Prospectus is deleted in its entirety and replaced with the following:
The Underlying Index is sponsored by MSCI, which is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.
