Management's Discussion of Fund Performance

The following discussion compares the performance of the Fund to the Russell 1000 Growth Index to show how the Fund’s performance compares to the returns of similar investments for the reporting period.

Management's Discussion of Fund Performance

The following discussion compares the performance of the Fund to the Russell 2000 Index to show how the Fund’s performance compares to the returns of similar investments for the reporting period. See the Average Annual Total Returns table below for the returns of the Fund and related indexes, including the Russell 3000 Index, a required broad-based index, which represents approximately 98% of investable U.S. equities by market capitalization. The Fund seeks to provide long-term capital appreciation by investing primarily in common stock of small U.S. companies.

    By sector, stock selection in Industrials, Financials and Communication Services aided performance.

  • Bullet

    Top individual Fund holdings that contributed positively to performance included overweight positions in Powell Industries, Inc., MaxLinear, Inc. and SSR Mining, Inc.

The Fund seeks to provide long-term capital appreciation by investing primarily in common stock of small U.S. companies.

    By sector, stock selection in Industrials, Financials and Materials aided performance.

  • Bullet

    Top individual Fund holdings that contributed positively to performance included overweight positions in MaxLinear, Inc., Powell Industries, Inc., and BrightSpring Health Services, Inc.
