BCK Blackrock California Insured Municipal Income Trust

Certain BlackRock closed-end funds (the “Funds”) announced distributions today as detailed below.

Several of the municipal Funds announced dividend increases. These dividend increases were made in order to better align the Funds with their current earnings rates in light of each fund’s earnings potential and level of undistributed net investment income.

In addition, dividend reductions were announced by several of the taxable and equity Funds. With respect to the taxable Funds, these dividend reductions take into account each Fund’s earnings potential and the decreasing interest rates on floating rate securities held by the Funds. With respect to the equity Funds, these dividend reductions take into account each Fund’s earnings potential and NAV decline in light of the recent market environment for equities.

Details are as follows:

The BlackRock Dividend AchieversTM Trust (NYSE:BDV), BlackRock EcoSolutions Investment Trust (NYSE:BQR), BlackRock Enhanced Capital and Income Fund, Inc.

(NYSE: EGF) (collectively, the “Trusts”) have adopted a level distribution plan (the “Plan”) and employ 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 Trust’s Board. Under its Plan, each Trust 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 (the “Code”). If sufficient investment income is not available on a quarterly/monthly basis, the Trusts will distribute long-term capital gains and or return capital to their shareholders in order to maintain a level distribution.

The Trusts’ estimated sources of the distributions paid as of August 31, 2009 and June 30, 2009 and for their current fiscal year through August 31, 2009 and June 30, 2009 are as follows:

1 The Trusts estimate that they have distributed more than their 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 Trust'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 Trust’s investment experience during the remainder of its fiscal year and may be subject to changes based on tax regulations. The Trusts 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.
