Factors Affecting Performance [Text Block]

How did the Fund perform in the last year?

During the fiscal year ended March 31, 2026 (the “Fiscal Year”), the Beck Mack + Oliver Partners Fund (the “Partners Fund”) returned -1.05% net of fees and expenses, resulting in a net asset value of $24.45. By comparison, the S&P 500 Index (the “S&P 500”), which is the Partners Fund’s principal benchmark, returned +17.80%.

With respect to the underperformance of the Partners Fund relative to the S&P 500 during the Fiscal Year, our investment in Fiserv (“FISV”) detracted significantly from performance. At the beginning of 2025, FISV announced a new CEO, whom we researched intensely and about whom we arrived at a positive conclusion. Unfortunately, the performance of the underlying business was not as robust as we had previously underwritten, and we subsequently exited the position.

In addition, two of the Partners Fund’s largest positions, Apollo Global Management (“APO”) and Blackstone (“BX”) substantially underperformed the S&P 500 during the Fiscal Year. We believe that the recent underperformance represents a temporary share price drawdown.

Other positions that detracted from performance during the Fiscal Year include Arthur J. Gallagher, CoStar Group, and Roper Technologies. In all three instances, we believe the underlying investment thesis remains intact. Positive contributors to performance include Alphabet, Ferguson Enterprises, Hilton Worldwide Holdings, and Zurn Elkay Water Solutions.
