The Fund expects most of its income to be exempt from federal income tax, and dividends you receive paid from such income should be exempt from regular federal income tax. A portion of such dividends received by individual shareholders may be subject to alternative minimum tax. The Fund's distributions of any taxable net investment income and any net short-term capital gain (i.e., dividends) will be taxable to you as ordinary income, and distributions of any net capital gain (the excess of net long-term capital gain over net short-term capital loss) will be subject to tax as long-term capital gain.
