BlackRock Municipal 2018 Term Trust, BlackRock New York Municipal 2018 Term Trust and BlackRock California Municipal 2018 Term Trust

Each of BlackRock Municipal 2018 Term Trust (NYSE:BPK), BlackRock New York Municipal 2018 Term Trust (NYSE:BLH), and BlackRock California Municipal 2018 Term Trust (NYSE:BJZ) (each, a “Fund” and collectively, the “Funds”) is scheduled to distribute substantially all of its assets on or about December 31, 2018, when each Fund will terminate. In recognition that the Funds are approaching their final year of operation and in order that each Fund may begin to make such changes to the composition of its investment portfolio as are designed to preserve capital and facilitate the eventual distribution of Fund assets to shareholders on or about December 31, 2018, the Board of each Fund has approved changes to certain non-fundamental investment policies.

First, the Board of each Fund has approved eliminating the requirement for each Fund to be fully invested (at least 95% of net assets) in applicable tax-exempt bonds as described below. In connection with the elimination of this 95% requirement, the Board approval also provides that each Fund may invest in high-grade short term taxable securities subject to an after-tax yield assessment, and also subject to the Fund’s investment policy of investing at least 80% of its total assets in applicable tax-exempt bonds.

Second, the Board of each Fund has modified the Fund’s non-fundamental policy to invest no more than 10% of its total assets in securities of other open- or closed-end management investment companies that invest primarily in municipal bonds of the types in which the Fund may invest directly. The modified policy excludes from the 10% limit any investments in registered money market funds that invest primarily in municipal bonds of the respective type in which the Fund may invest directly, including BlackRock money market funds. With respect to BLH and BJZ, such investments may include registered money market funds that invest primarily in federally exempt municipal bonds (but not necessarily state tax exempt municipal bonds).

These actions do not require the Funds to begin the process of liquidating their assets or to make distributions to their shareholders, or restrict the Funds’ ability to continue to engage in any business otherwise permitted by their investment objectives, policies, and restrictions (including by making new investments and reinvestments and engaging in new business).

The Funds also announced today a decrease in their monthly distribution rates effective with their January distributions.
