Factors Affecting Performance [Text Block]
WHAT FACTORS INFLUENCED PERFORMANCE FOR THE PERIOD?
During the period, the Fund returned 9.78%. After leading the S&P 500 Value Index through the end of the 1st quarter, the Fund ended the fiscal year underperforming its benchmark, the Solactive GBS US 1000 Index, on the back of a difficult earnings reporting season which negatively impacted July’s performance. The Fund’s absolute returns benefited from overall strength in the U.S. equity market, and the Fund’s continued adherence to a disciplined, systematic investment process, anchored by valuation analysis.
During the period, the Fund’s portfolio-maintained exposure to cheaper companies as shown in forward price-to-earnings ratios, price-to-sales ratios, and price to free-cash-flow ratios that have been consistently lower than both the broader market and the S&P 500 Value Index. U.S. equity market performance from the April lows has been led by more speculative areas of the market, contributing to the Fund’s underperformance. Our overweight to the Health Care sector was a drag on performance, particularly during the month of July.

Factors Affecting Performance [Text Block]
WHAT FACTORS INFLUENCED PERFORMANCE FOR THE PERIOD?
From inception of 5/14/25 through 7/31/25, the Fund returned 4.09% (NAV) versus 7.80% for the Solactive GBS United States 1000 Index. The Fund benefited from an overall rising U.S. equity market and specifically in the small to medium sized company market segment.

During the period, the Fund was overweight the Energy sector and underweight the Financials sector relative to the Solactive 2500 Value Style MV Index. During the period, several individual companies within the Energy sector offered compelling value, in the PM’s opinion. The Fund principally invests in the Financials sector on a more opportunistically basis and will regularly exhibit a relative underweighting compared to the benchmark’s weighting in the sector. During the period, the Fund’s equity positions in the Energy sector led performance. Holdings in the Health Care sector were some of the largest detractors to performance during the period, as earnings disappointments occurred within the health insurance, pharmaceuticals and related areas during the period in question.
