Factors Affecting Performance [Text Block]

How did the Fund perform last year?

The Fund utilized commodity index-linked swaps as an effective means of gaining exposure to the UBS Constant Maturity Commodity Total Return Index.
Commodities showed mixed performance with metals standing out on the upside and some energy and agricultural commodities lagging. Inflationary pressures, demand, and geopolitical risks supported prices, while weaker-than-expected economic conditions in China and softer global growth expectations weighed on certain commodity markets at points during the period.
Industrial metals and precious metals were the Fund’s largest contributors, particularly copper and aluminum, while gold and silver also contributed meaningfully.
Energy and agricultural commodities were the Fund’s largest detractors, as declining oil prices and weakness in key crops reflected ample global supply and favorable growing conditions.

Factors Affecting Performance [Text Block]

How did the Fund perform last year?

From a sector perspective, information technology contributed the most to the Fund’s performance during the period, followed by financials and consumer discretionary. Real estate was the only detracting sector.

Factors Affecting Performance [Text Block]

How did the Fund perform last year?

During the period, commodities and resource equities rebounded, supported by improving global growth expectations, easing financial conditions and tightening supply across several key commodity markets. Gold prices reached record highs amid persistent geopolitical uncertainty and sustained central bank demand, while base and industrial metals benefited from supply constraints and growing demand tied to electrification, infrastructure investment and data-center-driven power needs. While concerns around China’s uneven economic recovery periodically weighed on sentiment, markets increasingly responded to underlying fundamentals.
On an absolute basis, the Fund’s exposure to Gold & Precious Metals and Base & Industrial Metals were the largest contributor to performance. Gold & Precious Metals companies benefited from significant margin expansion and Base & Industrial Metals companies advanced as copper and aluminum prices strengthened. Oil & Gas also contributed positively for much of the period, supported by capital discipline and shareholder return programs.
From a sector standpoint, the Fund’s largest absolute detractors were Paper & Forest and Other Materials.
On an individual security basis, the Fund’s largest contributors included gold mining companies Kinross Gold, Barrick Mining Corp. and Newmont Corp, all of which benefited from record gold prices, strong free cash flow generation and disciplined capital allocation. The largest individual detractors included International Paper Co, Graphic Packaging Holding and West Fraser Timber Co. Ltd., reflecting weaker crop protection demand, inventory normalization and softer packaging and construction-related activity.
Relative to the benchmark, the S&P Global Natural Resources Index, the Fund outperformed primarily due to overweight positioning and strong security selection within Gold & Precious Metals, a substantial underweight allocation to Paper & Forest, and effective security selection within Base & Industrial Metals.

Factors Affecting Performance [Text Block]

How did the Fund perform last year?

During the period, gold prices remained well supported, reflecting continued central bank demand, easing monetary policy expectations and persistent geopolitical uncertainty. Gold mining equities benefited from higher realized gold prices and disciplined cost management, which supported cash flow generation and balance sheet strength across much of the industry.
On an absolute basis, the Fund’s exposure to senior and major gold miners was the largest contributor to performance. Among them, Agnico Eagle Mines was the top contributor for the period and AngloGold Ashanti also performed well. Among growth-oriented producers, G Mining Ventures was a significant contributor as investors continued to recognize the quality and scale of its development pipeline.
Mid-tier gold miners were also additive overall, supported by selective exposure to companies with visible production growth and improving margins. While junior developers and producers delivered strong returns overall, performance within the segment was more dispersed, reflecting project-specific execution risks and financing considerations.
On the detractor side, exposure to non-core holdings and early-stage exploration companies weighed modestly on results. Freeport-McMoRan detracted slightly as copper market volatility and macro uncertainty pressured sentiment, while Spartan Resources and Tectonic Metals were negatively impacted by exploration-related uncertainty and limited near-term catalysts.
Relative to the benchmark, the NYSE Arca Gold Miners Index, the Fund benefited from positive security selection across all segments and an overweight to junior developers. Allocation effects were modest, with overweights to bullion and cash detracting.

Factors Affecting Performance [Text Block]

How did the Fund perform last year?

Emerging markets bonds delivered strong gains in 2025 driven by appreciation in local currencies from a weaker US dollar, high income from sovereign local bonds, and a decline in bond yields in emerging markets.
Relative to its benchmark, 50% J.P. Morgan GBI-EM Global Diversified Index / 50% J.P. Morgan EMBI Global Diversified Index, the Fund outperformed primarily due to selective country positioning within sovereign debt.
In terms of country of risk, South Africa, Mexico, and Brazil were the top contributors to performance while Ukraine, Kazakhstan, and Turkey detracted the most.
Sovereign bonds contributed the most to performance, while the quasi-sovereign segment detracted slightly during the period.

Factors Affecting Performance [Text Block]

How did the Fund perform last year?

The Fund posted positive performance for the period but faced some headwinds relative to broad-based market indexes due to its underweight to tech-oriented companies, particularly mega-cap tech companies.
Despite its relative underweight, the technology sector contributed the most to the Fund’s performance during the period followed by industrials and healthcare stocks.
The leading individual contributors were Huntington Ingalls Industries, Applied Materials, and Teradyne.
The consumer defensive sector detracted the most during the period.
The leading individual detractors were Constellation Brands and Brown-Forman, both global beverage manufacturers, and Bio-Rad Laboratories Inc.

Factors Affecting Performance [Text Block]

How did the Fund perform last year?

The Fund posted positive performance for the period but faced some headwinds relative to broad-based market indexes due to its underweight to tech-oriented companies, particularly mega-cap tech companies.
Despite its relative underweight, the technology sector contributed the most to the Fund’s performance during the period followed by industrials and healthcare stocks.
The leading individual contributors were Huntington Ingalls Industries, Applied Materials, and Teradyne.
The consumer defensive sector detracted the most during the period.
The leading individual detractors were Constellation Brands and Brown-Forman, both global beverage manufacturers, and Bio-Rad Laboratories Inc.

Factors Affecting Performance [Text Block]

How did the Fund perform during the period?

The onchain economy delivered a strong year overall during the period from the Fund’s inception through year-end, despite intermittent market volatility. Performance was supported by generally positive trends across digital asset–related equities and continued investment in companies enabling blockchain adoption and digital infrastructure.
The Fund’s largest individual contributors were Cipher Mining Inc. and IREN Ltd. Both companies benefited from improving bitcoin mining economics and investor demand for large-scale, vertically integrated digital infrastructure platforms, supported by access to power, efficient operations, and expanding data center capacity tied to digital asset activity. Strategy Inc. was the largest detractor as digital asset treasury companies saw a pullback during the second half of 2025 due to bitcoin’s price fall.
At the sector level, Financial Services contributed the most to Fund performance, followed by Technology and Utilities. These sectors reflected strength across companies supporting digital asset markets, infrastructure, and related services.
