The Fund seeks to meet its investment objective generally by investing in component securities of the Bloomberg Barclays 2024 Term High Yield and Income Index. The Fund will invest at least 80% of its assets in the component instruments of the Underlying Index, and (except during the last twelve months of the Funds operations) the Fund will invest at least 90% of its assets in fixed income securities of the types included in the Underlying Index that BFA believes will help the Fund track the Underlying Index. The Fund will invest no more than 10% of its assets in futures, options and swaps contracts that BFA believes will help the Fund track the Underlying Index as well as in fixed income securities other than the types included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index
