[1] As described in the “Management of the Funds” section of the Fund’s prospectus beginning on page 72, pursuant to the management agreement between BlackRock Advisors, LLC (“BlackRock”) and BlackRock Allocation Target Shares, on behalf of the Fund, BlackRock has contractually agreed to waive all fees and pay or reimburse all fees and expenses of the Fund, except extraordinary expenses, indefinitely. Extraordinary expenses may include Dividend Expense, Interest Expense, Acquired Fund Fees and Expenses and certain other Fund expenses.
[2] You should also be aware that the Fund is an investment option for certain “wrap-fee” programs or other separately managed account clients for which BlackRock Investment Management, LLC or certain of its affiliates (individually or collectively referred to as “BIM LLC”) receives compensation pursuant to an investment management agreement. Wrap-fee program participants pay a “wrap-fee” to the sponsor of the program which typically covers investment advice and transaction costs on trades executed with the sponsor or a designated broker-dealer. You should read carefully the wrap-fee or other program brochure provided to you by your program sponsor or investment adviser. The brochure is required to include information about the fees charged to you and, in case of a wrap-fee program, the fees paid by the sponsor to BIM LLC.
