Overview

Investment Approach

BlackRock MuniAssets Fund, Inc.’s (MUA) (the 'Fund') investment objective is to provide high current income exempt from federal income taxes by investing primarily in a portfolio of medium- to lower-grade or unrated municipal obligations, the interest on which, in the opinion of bond counsel to the issuer, is exempt from federal income taxes. The Fund seeks to achieve its investment objective by investing, under normal market conditions, at least 80% of its assets in municipal bonds exempt from federal income taxes (except that the interest may be subject to the federal alternative minimum tax). The Fund invests at least 65% of its assets in municipal bonds that are rated in the medium to lower categories by nationally recognized rating services (for example, Baa or lower by Moody’s Investors Service, Inc. or BBB or lower by Standard & Poor’s Corporation) or non-rated securities which are of comparable quality. The Fund may invest directly in such securities or synthetically through the use of derivatives.

No assurance can be given that the Fund's investment objective will be achieved.

Past distributions are not indicative of future distributions.


If a Fund estimates that it has distributed more than its income and net realized capital gains in the current fiscal year; a portion of its distribution may be a return of capital. A return of capital may occur, for example, when some or all of a 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'. When distributions exceed total return performance, the difference will reduce the Fund's net asset value per share. Although the character of income will not be determined until the end of the fund’s fiscal year, please refer to the 'Closed-End Fund Resources' section of the BlackRock website for Section 19 notices that provide estimated amounts and sources of the fund's distributions, which should not be not be relied upon for tax reporting purposes. A Form 1099-DIV for the calendar year will be sent to shareholders to illustrate how the Fund’s distributions should be reported for federal income tax purposes.

The performance quoted represents past performance and does not guarantee future results. Investment return and principal value of an investment will fluctuate so that an investor’s shares, when redeemed or sold, may be worth more or less than the original cost. Current performance may be lower or higher than the performance quoted. Performance data current to the most recent month end may be found in the Performance section.

Returns are shown net of advisory fees paid by the fund and net of the fund’s operating fees and expenses. Numbers may reflect small variances due to rounding. Investors who purchase shares of the fund through an investment adviser or other financial professional may separately pay a fee to that service provider. The fund’s market price and net asset value will fluctuate with market conditions. All return data assumes reinvestment of all distributions. The return of your investment may increase or decrease as a result of currency fluctuations if your investment is made in a currency other than that used in the past

The fund itself has not been rated by an independent rating agency. Credit quality ratings on underlying securities of the fund are received from S&P, Moody’s and Fitch and converted to the equivalent S&P major rating category. This breakdown is provided by BlackRock and takes the median rating of the three agencies when all three agencies rate a security the lower of the two ratings if only two agencies rate a security and one rating if that is all that is provided. Unrated securities do not necessarily indicate low quality. Below investment-grade is represented by a rating of BB and below. Ratings and portfolio credit quality may change over time.

Notional value represents a fund’s use of derivatives, including but not limited to futures, options, and swaps. This value captures the fund exposures as if the derivative was replaced with the underlying asset and the corresponding financing or lending, such that all exposures sum to the net asset value. For non-derivatives, the market value and the notional value are identical.

Allocations are subject to change.
