Factors Affecting Performance [Text Block]
HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE?
For the twelve-months ended May 31, 2025, relative performance for the Jensen Quality Growth Fund was aided by overweight positions in the Industrials and Materials sector and underweights in the Energy and Real Estate sectors. Stock selection benefited relative Fund performance in the Health Care, Industrials, and Materials sectors. Relative performance was hindered by the Fund’s overweight position in the Consumer Staples, Information Technology, and Health Care sectors and underweight positions in the Consumer Discretionary, Communication Services, Financials, and Utilities sectors. Stock selection detracted from relative performance in the Consumer Discretionary, Communication Services, Consumer Staples, Financials, and the Information Technology sectors.
During the period, the strategy continued its high allocation to quality companies, as defined by the S&P Earnings and Dividend Quality Rankings. The Fund’s allocation to the highest-quality companies — those rated A+, A and A- — averaged 52.46% of portfolio assets compared to 31.74% of the S&P 500 Total Return Index. This significant overweight to quality detracted from the Fund’s relative returns during the period, which we believe were driven by increased investor appetite for risk despite increased geopolitical and trade policy uncertainty.
