Factors Affecting Performance [Text Block]

How did the Fund perform last year?

The Fund's Institutional Class generated a total return of 28.92% during the 12 months ended December 31, 2025.

• The Fund outperformed the S&P 500^® Index (Index) attributable to effective stock selection and sector allocation decisions. The Fund also benefited from its focus on growth companies, which outperformed value-oriented stocks.

• Stock selection in financials, health care and industrials contributed most positively. An overweight to information technology also boosted relative results. Stock selection in communication services and energy and an overweight to consumer discretionary detracted.

• Individual stocks contributing most positively to the Fund’s relative results were Robinhood Markets, a financial services platform operator; AppLovin, a mobile technology company; and Advanced Micro Devices, a semiconductor company. Robinhood Markets enjoyed a triple-digit share price gain on financial performance, product diversification, market expansion and inclusion in the Index in September 2025. AppLovin, a new Fund position, saw a triple-digit share price gain, reflecting its strategic focus on ad technology, financial performance and market expansion. Shares of Advanced Micro Devices saw a robust double-digit gain on its AI partnerships and demand for the company’s AI accelerators.

• Stocks detracting most from the Fund’s relative performance were Strategy, an enterprise analytics software provider that invests in Bitcoin; ServiceNow, a cloud-based solutions provider for digital workflows; and CoreWeave, an AI cloud-computing company—each of which saw a double-digit share price decline. An out-of-Index position in Strategy hurt, reflecting Bitcoin’s price volatility and investor concerns about financing Bitcoin purchases. ServiceNow struggled amid concerns about the impact of AI on its core human resources business and decelerating growth. A new out-of-Index position in CoreWeave was negatively affected by data center delays pressuring its revenue and concerns around its high debt/capital expenditure ratio.

Performance Past Does Not Indicate Future [Text]

<p style="box-sizing: border-box; color: rgb(0, 0, 0); display: block; flex-wrap: nowrap; font-size: 9.33333px; font-weight: 400; grid-area: auto; line-height: 11.2px; margin: 0px; overflow: visible; text-align: justify; text-align-last: left; white-space-collapse: preserve-breaks;">The performance data quoted represent past performance and are no guarantee of future performance. The investment return and principal value of an investment will fluctuate so that an investment, when redeemed, may be worth more or less than its original cost. The performance data includes reinvestments of all dividends and distributions but does not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares.</p>
