Factors Affecting Performance [Text Block]

What factors materially affected the Fund's performance over the last year?

Long-term U.S. Treasury yields ended the reporting period higher than where they began, reaching their lows in April of 2025 before hitting period highs in May of 2025. Yields fluctuated through the remainder of 2025, driven by mixed or missing economic data and evolving views on monetary policy easing. During the third and fourth quarters of 2025, the Federal Reserve reduced its target rate three times, broadly in line with market expectations, citing employment risks and a desire to support continued economic expansion. Long-term U.S. Treasury yields ended the period near recent highs as geopolitical uncertainty weighed on inflation and growth outlooks.

Factors Affecting Performance [Text Block]

What factors materially affected the Fund's performance over the last year?

High yield generated positive returns for the reporting period. At the beginning of the reporting period, risk assets experienced some volatility due to macro-economic factors stemming from trade negotiations and tariffs. After the initial market shock of increased tariffs on trading partners, risk assets rebounded. During the later part of first quarter of 2026 geopolitical events weighed on the high yield market. All sectors contributed positively to the Bloomberg U.S. Corporate High Yield Index with notable positive contribution from communications and consumer discretionary. On the ratings side, BB-rated holdings were a leading contributor to index returns.

Factors Affecting Performance [Text Block]

What factors materially affected the Fund's performance over the last year?

During the reporting period, the U.S. Federal Open Market Committee ("FOMC") lowered the federal funds target range by 75 basis points as job gains slowed while inflation remained above the Fed’s target. One basis point is equal to 0.01%. In Q3 and Q4 of 2025, downside risks to employment resulted in the FOMC lowering the target range for the federal funds by 25 basis points three times to the 3.5-3.75 percent range. During Q1 2026 the unemployment rate looked to be stabilizing but recent geopolitical events have added some economic uncertainty to the market. By the end of the reporting period, markets were not expecting any further cuts to the Federal Fund’s rate through the remainder of 2026.
