Fund inception: 7/28/2004.

Performance represents past performance and does not guarantee future results. Investment returns and the principal value of an investment will fluctuate so that an investor’s shares, when redeemed, may be worth more or less than their original cost. Current performance may be lower or higher than the performance quoted.

Performance reflects the deduction of management fees and other applicable expenses and assumes that all rights in the Fund’s rights offering were exercised. Dividends and distributions, if any, are assumed for the purpose of this calculation to be reinvested at a price obtained under the Fund’s dividend reinvestment plan. Returns do not reflect brokerage commissions on the purchase or sale of the Fund’s shares. Performance information shown does not reflect the deduction of taxes that shareholders would pay on Fund distributions or the sale of Fund shares. An investment in the Fund involves risk, including loss of principal.
