* In order to comply with the requirements of Section 19 of the Investment Company Act of 1940, as amended, each of the Funds noted above posted to the DTC bulletin board and sent to its shareholders of record as of the applicable record date a Section 19 notice with the previous distribution payment. The Section 19 notice was provided for informational purposes only and not for tax reporting purposes. This information can be found in the “Closed-End Funds” section of www.blackrock.com. As applicable, the final determination of the source and tax characteristics of all distributions in 2015 will be made after the end of the year.

(NYSE:CII), BlackRock Science and Technology Trust (NYSE:BST), and BlackRock Enhanced Government Fund, Inc. (NYSE:EGF) (collectively, the “Plan Funds”) have adopted a level distribution plan (a “Plan”) and employ a managed distribution and/or 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 Plan Fund’s Board of Directors/Trustees. Under its Plan, each Plan 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, each Plan Fund will distribute long-term capital gains and/or return capital to its shareholders in order to maintain a level distribution.

The Plan Funds’ estimated sources of the distributions paid as of February 27, 2015 and for their current fiscal year are as follows:

1 The Plan Fund estimates that it has distributed more than its income and net realized capital gains in the current fiscal year; therefore, a portion of the distribution may be a return of capital. A return of capital may occur, for example, when some or all of the shareholder’s investment is paid back to the shareholder. A return of capital distribution does not necessarily reflect a Plan Fund's investment performance and should not be confused with ‘yield’ or ‘income’. When distributions exceed total return performance, the difference will reduce the Plan Fund’s net asset value per share.

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