Performance Summary THROUGH 11/30/24 The following chart illustrates the fund’s historical performance in comparison to its benchmark(s). Performance results reflect the percentage change in net asset value and market value, including reinvestment of fund distributions. Benchmarks are unmanaged and may not be invested in directly. Benchmark returns do not reflect commissions or expenses. (See Notes to Performance Summary.) Performance data shown represents past performance and is no guarantee of future results. Investment return and principal value fluctuate so your shares, when sold, may be worth more or less than the original cost; current performance may be lower or higher than quoted. The performance shown does not reflect the deduction of taxes, if any, that a shareholder would pay on fund distributions or the sale of fund shares.
