Example: The following example illustrates the expenses that common shareholders would pay on a $1,000 investment in common shares (including an assumed total sales load or commission of 1.00%), assuming (1) total annual expenses of 4.26% of net assets attributable to common shareholders; (2) a 5% annual gross return; and (3) all distributions are reinvested at net asset value:

The example should not be considered a representation of future expenses. Actual expenses may be greater or less than those assumed. Moreover, our actual rate of return may be greater or less than the hypothetical 5% return shown in the example.
