Factors Affecting Performance [Text Block]

What affected the Fund's performance this period?

•Investors in global real estate securities experienced fluctuating market conditions throughout the 12 months ending July 31, 2024, initially declining due to rate hike concerns but later rallying as hopes for rate cuts in 2024 grew. Market returns were weakened by a broadly stronger U.S. dollar.

•Against this backdrop, stock picks in Japan and the U.K. detracted from the fund's performance versus the benchmark for the fiscal year. By sector, an overweight among real estate development stocks hurt the most.

•The largest individual relative detractor was untimely positioning in Mitsui Fudosan (+56%), a stake we established this period. Outsized exposure to CK Asset Holdings (-30%), one of the fund's largest holdings, and an underweight in Vonovia (+36%) also hurt.

•In contrast, security selection in Asia Pacific ex Japan and Europe ex U.K. contributed to the fund's relative performance. Stock picking in the real estate development industry led the way among relative contributors on a sector basis.

•The top individual relative contributor was timely positioning in Sun Hung Kai Properties (-27%), an investment we established this period. Not owning Wharf Real Estate Investment, an index component that returned -52%, was another plus, as was a non-index stake in Arvida (+26%). This period we decreased our investment in Arvida.

•Notable changes in positioning include increased exposure to France and Australia. By industry, meaningful allocation shifts include decreased exposure to the diversified and integrated telecommunication services industries.

How has the Fund changed?

This is a summary of certain changes to the Fund since August 1, 2023.

The fund's transfer agent and pricing & bookkeeping fees were changed to a fixed rate effective December 1, 2023, through February 29, 2024, in anticipation of the transition to a new management fee structure. Effective March 1, 2024, the fund's management contract was amended to incorporate administrative services previously covered under separate services agreements (transfer agent and pricing & bookkeeping). The amended contract incorporates a management fee rate that may vary by class. The Adviser or an affiliate pays certain expenses of managing and operating the fund out of each class's management fee.

Factors Affecting Performance [Text Block]

What affected the Fund's performance this period?

•U.S. equities gained for the 12 months ending July 31, 2024, driven by resilient corporate profits, a frenzy over generative artificial intelligence and the Federal Reserve's likely pivot to cutting interest rates later this year.

•Against this backdrop, industry positioning was the primary detractor from the fund's performance versus the MSCI US IMI Real Estate 25/50 Linked Index for the fiscal year, especially an underweight among office real estate investment trusts. Subpar security selection in the telecom tower and retail industries hurt as well.

•The biggest individual relative detractor was an outsized stake in SBA Communications (+1%). This period we decreased our position in the stock, though it was still one of the fund's largest holdings this period. Avoiding Simon Property Group, an index component that gained roughly 30%, proved detrimental to performance as well. A larger-than-index position in Mid-America Apartment Communities (-3%) also hurt.

•In contrast, the primary contributor to performance versus the real estate index was security selection in health care. Solid picks among "other specialized" REITs also boosted the fund's relative performance. Favorable investment choices and an underweight in real estate services helped as well.

•The top individual relative contributor was an outsized stake in Ventas (+16%), one of our largest holdings. Timely positioning in CoStar Group (-7%) and comparatively light exposure to Realty Income (-1%) also proved advantageous.

•Notable changes in positioning include increased exposure to the self storage industry and a lower allocation to hotel & resort REITs.
