The portfolio manager also uses quantitative portfolio construction tools as part of the investment process. The Fund defines small- and mid-cap securities as companies with market caps within the collective range of the Russell 2500 Index. As of June 30, 2026, this range was approximately $8.53 million to $30.65 billion for the Russell 2500 Index. The market capitalization range of this index changes over time.
