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

The Fund returned 20.33% (NAV) for the Period, compared with 19.56% for the S&P 500 Index. Performance reflected broad participation across a portfolio of dividend-paying companies selected for financial strength, free cash flow generation, and the ability to sustain and grow distributions. Relative performance was influenced by the Fund's differentiated sector positioning. An overweight to Energy benefited results amid strong performance in the sector, while an underweight to Information Technology limited participation in that sector's gains. Consistent with the Fund's dividend growth mandate, 31 of the Fund's 37 equity holdings as of fiscal year-end increased their dividends during the Period. The Fund continues to use bottom-up fundamental analysis to identify well-run companies with durable cash flows, sustainable payout profiles, and the capacity to both reinvest in their businesses and return growing income to shareholders.
