Note: Except the most recent quarter, the expense ratios presented are the funds' actual operating expenses and they exclude any acquired fees and expenses, which result from the funds' holding in business development companies (BDCs). BDCs expenses are not direct costs paid by fund shareholders and are not used to calculate the funds' net asset value.

The performance data shown represent past performance, which is not a guarantee of future results. Investment returns and principal value will fluctuate, so investors' shares, when sold, may be worth more or less than their original cost. Current performance may be lower or higher than the performance data cited.

The performance data shown represents past performance, which is not a guarantee of future results. Investment returns and principal value will fluctuate, so that investors' shares, when sold, may be worth more or less than their original cost. Current performance may be lower or higher than the performance data cited.

Performance data for periods of less than one year does not reflect the deduction of purchase and redemption fees. Maintenance, low balance, and service fees may be assessed by some funds. None of these fees are reflected in the performance figures. If these fees were included, the performance would be lower. All other performance data are adjusted for purchase and redemption fees, where applicable. See Fees & Costs below for expense ratio and additional fee details.

The performance of an index is not an exact representation of any particular investment, as you cannot invest directly in an index. Benchmark comparative indexes represent unmanaged or average returns on various financial assets, which can be compared with funds' total returns for the purpose of measuring relative performance.
