Factors Affecting Performance [Text Block]
WHAT FACTORS INFLUENCED PERFORMANCE FOR THE PERIOD?

During the Period, the Sub-Adviser maintained its commitment to active risk management and managed the Fund with a bias that markets may remain in the late stages of the business cycle that began in May of 2020. This approach resulted in the Fund capturing a portion of the S&P 500 returns, while holding approximately 40-80% cash and cash alternatives for most of the Period.

The Fund’s allocation utilized tranches to tax-efficiently scale into and out of equities based on the proprietary breadth indicators of the overall equity markets. This process is independent of market headlines, removing any manager’s assumption of the market response to a particular event.
The Fund’s performance over the Period demonstrated less volatility, smaller drawdowns, and faster recovery than the S&P 500 benchmark and then grew at a slower pace than the benchmark once the breadth indicators signaled strong but weakening breadth. In April 2025, the benchmark S&P 500 experienced a meaningful drawdown from the recent highs of February 2025 due in part to headlines around tariffs. The Fund maintained its focus on breadth indicators and was allocated to roughly 68% cash or cash alternatives prior to the decline of the benchmark. This contributed to the Fund experiencing a smaller drawdown than the benchmark during this period of volatility. The Fund experienced approximately a 9% drawdown from recent highs. The Fund made multiple purchases of equities and reduced its cash and cash alternative allocation during the month of March 2025 through April 2025. This rebalancing allowed the Fund to take advantage of lower prices in large-cap equities, while not experiencing the same level of drawdown. During the following months, the Fund tax-efficiently sold portions of the equity allocation, building the cash and cash alternative portion back to approximately 78% of the allocation by mid-August 2025. This process of management allowed the Fund to benefit from growth of the benchmark during the Period with lower volatility. However, as expected with this process seeking lower volatility, when the benchmark continued to make new highs, the growth of the Fund slowed in relation to the overall benchmark. The Fund’s risk management process of utilizing breadth indicators as the primary signal to take on more or less risk demonstrated success during the Period.
