Diversification

For each fund:

In order to qualify as a "regulated investment company" under Subchapter M of the Internal Revenue Code of 1986 (Code), as amended, the fund currently intends to comply with certain diversification limits imposed by Subchapter M.

For purposes of the fund's diversification limitation discussed above, Subchapter M generally requires the fund to invest no more than 25% of its total assets in securities of any one issuer and to invest at least 50% of its total assets so that (a) no more than 5% of the fund's total assets are invested in securities of any one issuer, and (b) the fund does not hold more than 10% of the outstanding voting securities of that issuer. However, Subchapter M allows unlimited investments in cash, cash items, government securities (as defined in Subchapter M) and securities of other regulated investment companies. These tax requirements are generally applied at the end of each quarter of the fund's taxable year.
