Under normal market conditions, the Fund will invest substantially all of its assets in FLexible EXchange Options (FLEX Options) that reference the price performance of the iShares MSCI EAFE ETF (the Underlying ETF). FLEX Options are customized equity or index option contracts that trade on an exchange, but provide investors with the ability to customize key contract terms like exercise prices, styles and expiration dates. The Underlying ETF is an exchange-traded fund that generally invests at least 90% of its assets in securities of the MSCI EAFE Index and in depositary receipts representing securities of the MSCI EAFE Index. BlackRock Fund Advisors (BFA) serves as the Underlying ETFs adviser. The investment objective of the Underlying ETF is to seek to track the investment results of the MSCI EAFE Index, which is composed of large- and mid-capitalization developed market equities, excluding the U.S. and Canada. The Fund's performance will not reflect the payment of dividends by theUnderlying ETF. See TheUnderlying ETF formore information.
