TOB Residuals represent
beneficial interests in a TOB Trust. A TOB Trust typically issues two classes of beneficial interests: TOB Floaters, which are sold to third party investors, and TOB Residuals, which are generally issued to the fund(s) that transferred municipal
bonds to the TOB Trust. MIY may invest in both TOB Floaters and TOB Residuals. TOB Floaters may have first priority on the cash flow from the municipal bonds held by the TOB Trust and are enhanced with a liquidity support arrangement from TOBs
Liquidity Provider which allows holders to tender their

107

position at par (plus accrued interest). MIY, as a holder of TOB Residuals, is paid the residual cash flow from the TOB Trust after payment of TOB Trust expenses and interest on the TOB Floaters.
MIY contributes municipal bonds to the TOB Trust and is paid the cash received by the TOB Trust from the sale of the TOB Floaters, less certain transaction costs, and typically will invest the cash to purchase additional municipal bonds or other
investments permitted by its investment policies. If MIY ever purchases all or a portion of the TOB Floaters sold by the TOB Trust, it may surrender those TOB Floaters together with a proportionate amount of TOB Residuals to the TOB Trust in
exchange for a proportionate amount of the municipal bonds owned by the TOB Trust.

Other BlackRock-Advised Funds may contribute municipal
bonds to a TOB Trust into which MIY has contributed municipal bonds. If multiple BlackRock-Advised Funds participate in the same TOB Trust, the economic rights and obligations under the TOB Residual will generally be shared among the funds ratably
in proportion to their participation in the TOB Trust.

The municipal bonds transferred to a TOB Trust typically are high grade municipal
bonds. In certain cases, when municipal bonds transferred are lower grade municipal bonds, the TOB Trust transaction includes a credit enhancement feature that provides for the timely payment of principal and interest on the bonds to the TOB Trust
by a credit enhancement provider. The TOB Trust would be responsible for the payment of the credit enhancement fee and MIY, as a TOB Residual holder, would be responsible for reimbursement of any payments of principal and interest made by the credit
enhancement provider
