Factors Affecting Performance [Text Block]

What affected the Fund's performance this period?

•U.S. stocks achieved a strong gain for the 12 months ending January 31, 2026, extending a historically fast rebound that began in early April, bolstered by strong corporate fundamentals, a resilient economy and, beginning in September, the Federal Reserve's first interest-rate reductions since December 2024.

•Against this backdrop, market selection was the primary detractor from the fund's performance versus the Russell 3000 Telecom and Utilities Select Index for the fiscal year, especially an overweight in the independent power producers & energy traders industry. Stock picks in electric utilities also hampered the fund's result. Also detracting from our result was an overweight in the cable & satellite industry.

•The largest individual relative detractor was an overweight in Constellation Energy (-6%). The stock was one of our biggest holdings. A second notable relative detractor was an overweight in NRG Energy (+3%). This was a position we established this period. The stock was among our largest holdings at period end. Another notable relative detractor was our stake in Verizon Communications (+21%). The company was the fund's second-largest holding at period end.

•In contrast, the primary contributor to performance versus the sector index was stock picking in coal & consumable fuels, a segment that is not part of the index. Picks and an overweight in the heavy electrical equipment category also boosted relative performance. Also helping our relative result was stock selection in the cable & satellite industry.

•The top individual relative contributor was our stake in Cameco (+144%). This was a position we established this period. A second notable relative contributor was our stake in GE Vernova (+89%), which we reduced. Another notable relative contributor was our stake in Nextpower (+97%). This was a stake we established this period. All these contributors were non-index positions.

•Notable changes in positioning include lower allocations to the integrated telecommunication services and wireless telecommunication services industries.
