Today, BlackRock Real Asset Equity Trust (NYSE: BCF), BlackRock Resources & Commodities Strategy Trust (NYSE: BCX), BlackRock Enhanced Equity Dividend Trust (NYSE: BDJ), BlackRock Strategic Equity Dividend Trust (NYSE: BDT), BlackRock Equity Dividend Trust (NYSE: BDV), BlackRock Energy and Resources Trust (NYSE: BGR), BlackRock International Growth and Income Trust (NYSE: BGY), BlackRock Health Sciences Trust (NYSE: BME), BlackRock EcoSolutions Investment Trust (NYSE: BQR), BlackRock S&P Quality Rankings Global Equity Managed Trust (NYSE AMEX:BQY) and BlackRock Enhanced Capital and Income Fund, Inc. (NYSE: CII) (collectively, the "Funds") paid the following dividends per share:

Each of the Funds has adopted a level distribution plan (the "Plan") and employs either a managed distribution 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 Fund's Board of 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 quarterly/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 years are as follows:

¹The Fund estimates that it has distributed more than its income and capital gains in the current fiscal year; therefore, a portion of your 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 Fund's investment performance and should not be confused with 'yield' or 'income'.

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 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.

* Portfolio launched within the past 5 years; this represents the average annual total return (in relation to NAV) from inception to 11/30/2011.

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.
