| Factors Affecting Performance [Text Block] | Management's Discussion of Fund Performance The following discussion compares the performance of the Fund to the S&P 500 ® Top Contributors to Performance The Fund provided a dividend yield more than two times that of the Index which contributed positively to relative performance. Stock selection in the Financials sector contributed positively to relative performance. Outperformers included PNC Financial Services, Morgan Stanley, JP Morgan Chase & Co. and Truist Financial Corporation. Stock selection in the Health Care sector was also a positive relative contributor to performance, driven by robust performance from Amgen and AbbVie. Stock selection in the Consumer Staples sector was another area of relative strength, led by superior performance from Philip Morris International and Target Corporation. Top Detractors from Performance The Fund’s largest relative detractor was the underweight position to the Information Technology sector. Information Technology accounted for 38% of the total performance of the Index. Information Technology continues to afford little in the way of high-and-rising dividend-paying companies. Stock selection in the Industrials sector was a relative detractor, as top performers in the Index such as Howmet Aerospace Inc., United Airlines Holdings, GE Vernova Inc., Axon Enterprise Inc. and United Rentals, Inc. either did not pay a dividend or paid a dividend notably lower than the Fund’s minimum threshold and, therefore, were not held by the Fund. Stock selection in the Communication Services sector was another area of relative weakness, as the Fund’s strategy is to invest in the defensive, dividend-paying telecom service names while the top performers in the sector were Meta Platforms, Alphabet and Netflix. These outperformers either did not pay a dividend or paid a dividend notably lower than the Fund’s minimum threshold and, therefore, were not held by the Fund. |
