                    BlackRock Taxable Municipal Bond Trust
                              File No. 811-22426
  Item No. 77D (Policies with Respect to Security Investments) -- Attachment

BlackRock Taxable Municipal Bond Trust ("BBN" or the "Trust") changed its
non-fundamental investment policy from "Under normal market conditions, the
Trust invests at least 80% of its managed assets in BABs" to "Under normal
market conditions, the Trust invests at least 80% of its managed assets in
taxable municipal securities, which include BABs." The Trust also changed its
name from "BlackRock Build America Bond Trust" to "BlackRock Taxable Municipal
Bond Trust." These changes became effective on August 25, 2015.

The Trust continues to maintain its other investment policies, including its
ability to invest up to 20% of its managed assets in securities other than
taxable municipal securities. Such other securities include tax-exempt
securities, U.S. Treasury securities, obligations of the U.S. Government, its
agencies and instrumentalities and corporate bonds issued by issuers that have,
in the investment adviser's view, typically been associated with or sold in the
municipal market, such as bonds issued by private universities and hospitals,
or bonds sold to finance military housing developments.

As used herein, "managed assets" means the total assets of the Trust (including
any assets attributable to money borrowed for investment purposes) minus the
sum of the Trust's accrued liabilities (other than money borrowed for
investment purposes) and "BABs" means taxable municipal securities known as
"Build America Bonds."
