Certain BlackRock Closed-End Funds Announce Estimated Sources of Distributions

Today, BlackRock Resources & Commodities Strategy Trust BCX, BlackRock Enhanced Equity Dividend Trust BDJ, BlackRock Energy and Resources Trust BGR, BlackRock Enhanced International Dividend Trust BGY, BlackRock Health Sciences Trust BME, BlackRock Enhanced Global Dividend Trust BOE, BlackRock Utilities, Infrastructure & Power Opportunities Trust BUI, BlackRock Enhanced Capital and Income Fund, Inc. CII, BlackRock Science and Technology Trust BST, and BlackRock Enhanced Government Fund, Inc. EGF (collectively, the "Funds") paid the following distributions per share:

Each of the Funds have adopted a managed distribution plan (the "Plan") and employ an option over-write policy to support a level distribution of income, capital gains and/or return of capital. The fixed amounts distributed per share are subject to change at the discretion of each Fund's Board of Directors/Trustees. Under its Plan, each Fund will distribute all available investment income to its shareholders, consistent with its primary investment objectives and as required by the Internal Revenue Code of 1986, as amended. If sufficient investment income is not available on a monthly basis, the Funds will distribute long-term capital gains and/or return capital to their shareholders in order to maintain a level distribution.

The Funds' estimated sources of the distributions paid this month and for their current fiscal year are as follows:

The amounts and sources of distributions reported are only estimates and are being provided to you pursuant to regulatory requirements and are not being provided for tax reporting purposes. The actual amounts and sources of the amounts for tax reporting purposes will depend upon each Fund's investment experience during the remainder of its fiscal year and may be subject to changes based on tax regulations. The Fund will send you a Form 1099-DIV for the calendar year that will tell you how to report these distributions for federal income tax purposes.

Shareholders should not draw any conclusions about a Fund's investment performance from the amount of the Fund's current distributions or from the terms of the Fund's Plan.

BKT has adopted a Plan whereby beginning August 2018 the Fund will make fixed monthly distributions to common stockholders and will distribute all available investment income to its stockholders, consistent with its investment objective and as required by the Code. The fixed amount distributed per share is subject to change at the discretion of BKT's Board. If sufficient investment income is not available on a monthly basis, the Fund will distribute long-term capital gains and/or return capital to its stockholders in order to maintain a level distribution. The Fund is currently not relying on any exemptive relief from Section 19(b) of the 1940 Act. The Fund expects that distributions under the Plan will exceed current income and capital gains and therefore will likely include a return of capital. BKT may make additional distributions from time to time, including additional capital gain distributions at the end of the taxable year, if required to meet requirements imposed by the Code and/or the 1940 Act.

BKT's estimated sources of the distributions paid as of February 28, 2019 and for its current fiscal year is as follows:

The amounts and sources of distributions reported are only estimates and are being provided to you pursuant to regulatory requirements and are not being provided for tax reporting purposes. The actual amounts and sources of the amounts for tax reporting purposes will depend upon BKT's investment experience during the remainder of its fiscal year and may be subject to changes based on tax regulations. BKT will send its stockholders a Form 1099-DIV for the calendar year that will illustrate how to report these distributions for federal income tax purposes.

No conclusions should be drawn about the BKT's investment performance from the amount of the Fund's distributions or from the terms of the Fund's Plan.

The amount distributed per share under a Plan is subject to change at the discretion of the applicable Fund's Board. Each Plan will be subject to ongoing review by the Board to determine whether the Plan should be continued, modified or terminated. The Board may amend the terms of a Plan or suspend or terminate a Plan at any time without prior notice to the Fund's shareholders if it deems such actions to be in the best interest of the Fund or its shareholders. The amendment or termination of a Plan could have an adverse effect on the market price of the Fund's shares.
