Factors Affecting Performance [Text Block]
WHAT FACTORS INFLUENCED PERFORMANCE FOR THE PERIOD?
The Fund returned 4.93% during the Period. The Fund operates as a “fund of funds” and allocates its assets among other U.S. fixed income funds that invest in a variety of fixed income sectors. Corporate credit contributed the largest positive impact to performance, driven by investment grade and high yield corporate bond holdings supported by coupon income, stable credit fundamentals, and tight credit spreads. Treasury holdings across the curve also contributed to performance, supported by declining interest rates following Federal Reserve policy rate reductions in late 2025. Securitized credit, collateralized loan obligation (CLO), and floating-rate allocations contributed modestly to performance. All fixed-income categories within the Fund contributed positively to performance during the Period. The Fund had no meaningful detractors during the period. The strategy carries risk and past results may not repeat.
Below were the largest contributors to Fund performance. The SPDR Portfolio Intermediate Term Corporate Bond ETF (SPIB) gained substantially during the period overall and accounted for a meaningful portion of the Fund’s performance.

WHAT FACTORS INFLUENCED PERFORMANCE FOR THE PERIOD?
The Fund returned 37.71% during the Period. The Fund primarily invests in common stock principally traded in the U.S. of companies that the Sub-Adviser believes exhibit robust quality characteristics with attractive valuations and dividend paying potential. Information Technology contributed the largest positive impact to performance, driven by holdings in memory, data storage, and semiconductor equipment companies benefiting from artificial intelligence-related demand and datacenter capital investment. Industrials also contributed positively, led by holdings tied to datacenter construction as well as electrical and cooling infrastructure. Software and Information Technology services holdings, including Accenture, Adobe, and Cognizant, detracted from performance due to share price declines associated with concerns regarding the impact of artificial intelligence adoption on demand for certain services. Financials detracted from performance, as losses in insurance and payment network holdings outweighed gains in bank and consumer finance holdings. Period returns also reflected interest rate movements, including evolving expectations around the Federal Reserve’s policy path, and episodic geopolitical volatility associated with conflicts in the Middle East, though corporate earnings remained supportive of risk assets.

Below are the largest contributors and detractors to fund performance. Western Digital Corporation gained the most for the period overall and accounted for a significant portion of the Fund’s overall performance.
