BlackRock Advisors, LLC (the “Advisor”) today announced that the Board of Trustees (the “Board”) of BlackRock Build America Bond Trust (NYSE:BBN, the “Trust”) has approved changes to certain non-fundamental investment policies and the name of the Trust.

The Trust will continue to pursue its primary investment objective of seeking high current income, with a secondary objective of capital appreciation. However, as a result of these investment policy changes, the Trust will no longer be required to invest a specific percentage of its managed assets in Build America Bonds (“BABs”).

The changes to the Trust’s current non-fundamental investment policies are as follows:

                             
        Current Policy       Changed Policy       Effective Date

Build
America
Bonds Policy

     

Under normal market
conditions, the Trust
invests at least 80% of its
managed assets in BABs

     

Under normal market
conditions, the Trust invests at
least 80% of its managed
assets in taxable municipal
securities, which include BABs

     

On or around
August 25, 2015

                 

In connection with the investment policy change above, the Trust will be required to change its name. Upon the effective date, the Trust will change its name to “BlackRock Taxable Municipal Bond Trust”. The Trust will continue to trade on the NYSE under its current ticker symbol, “BBN”.

Given the uncertainty around the BABs program at the time of the Trust’s launch in 2010, the Trust’s initial public offering prospectus included a provision whereby if, for any 24-month period, there were no new issuances of BABs or other analogous taxable municipal securities, the Board would undertake an evaluation of potential actions with respect to the Trust (the “Contingent Review Provision”). Under the Contingent Review Provision, such potential action may include changes to the Trust’s non-fundamental investment policies to broaden its primary investment focus to include taxable municipal securities generally.

Given that there have been no new issuances of BABs, the investment policy changes described herein reflect the Board’s evaluation of the Trust pursuant to the Contingent Review Provision. The Trust believes that these investment policy changes are appropriate at this time to potentially diversify the Trust’s portfolio by broadening its investment universe and to keep the Trust’s portfolio flexible enough to take advantage of relative value opportunities in the taxable municipal market as a whole.

The Trust will continue 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 and obligations of the U.S. Government, its agencies and instrumentalities and, effective on or about October 1, 2015, will include corporate bonds issued by issuers that have, in the Advisor’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.

No other changes to the Trust’s other investment policies or the Trust’s portfolio management team are currently anticipated, nor is it currently anticipated that there will be substantial portfolio turnover in conjunction with these changes in the immediate future.

No action is required by shareholders of the Trust in connection with these investment policy changes.
