Factors Affecting Performance [Text Block]
Management’s
Discussion
of Fund Performance
For the 12-month reporting period ended December 31, 2025, the Fund returned 3.52%, as compared to its broad-based securities market index, the Russell 3000
®
Index, which returned 17.15% and an additional index with investment characteristics similar to those of the Fund, the Dow Jones U.S. Select REIT Index, which returned 3.67% over the same period.
The Fund’s investment portfolio is managed by one sub-adviser: Keyridge Asset Management Limited (“Keyridge”) (formerly known as Irish Life Investment Managers Limited).
Keyridge Summary of Performance
Performance was affected by supportive monetary policy as the Federal Reserve resumed rate cuts to respond to labor market weakness, which benefited real estate stocks. Welltower Inc., a healthcare infrastructure real estate investment trust (“REIT”), was the largest contributor to performance due to increased occupancy levels and successful acquisitions. Prologis Inc., a logistics REIT, also contributed to performance as demand increased for more efficient distribution network solutions. Equinix, a data center REIT, detracted the most from performance as revenues slowed amid delays with business-to-business deal activity. Alexandria, an office REIT focused on life sciences, was also a detractor following the recognition of a significant non-cash impairment charge in the third quarter.
