Factors Affecting Performance [Text Block]

How did the Fund perform last year?

For the reporting period ended August 31, 2025, the Fund returned 8.01%.
For the same period, the MSCI ACWI ex USA Index (Net) returned 15.42% and the MSCI Australia Index (Net) returned 8.38%.

What contributed to performance?

The financials sector was the largest contributor to the Fund’s return during the reporting period. The banking industry experienced profit growth, led by loan portfolio expansion and declining non-performing loans. Insurance firms gained amid premium growth and increasing demand for health coverage and climate-related disasters. Consumer discretionary stocks also contributed during the reporting period, most notably in the broadline retail industry. This included Australia’s largest conglomerate with a diverse portfolio of businesses in retail and industrial sectors. The firm’s highly successful retail chains, along with its other diverse operations, helped drive growth.

What detracted from performance?

Firms in the healthcare sector detracted the most from the Fund’s return during the reporting period. A global biotechnology company was pressured as its core division that develops treatments for immunodeficiencies and bleeding disorders, reported revenue below expectations. The firm also announced plans to demerge its flu vaccine business, pushing shares lower.

Factors Affecting Performance [Text Block]

How did the Fund perform last year?

For the reporting period ended August 31, 2025, the Fund returned 22.86%.
For the same period, the MSCI Emerging Markets Index (Net) returned 16.80% and the MSCI Mexico IMI 25/50 Index (Net) returned 23.29%.

What contributed to performance?

Stocks in the materials sector contributed meaningfully to the Fund’s return during the reporting period. In the metals and mining segment, a major copper producer gained due to rising prices and increased global demand due to the metal’s use in the green energy transition and electric vehicles. Additionally, a mining company that is a significant explorer and producer of gold and silver saw tailwinds as the prices of these metals gained due to their perceived status as a safe-haven investment. Financials stocks also contributed, particularly diversified banks, which were supported by resilient loan growth, solid profit margins, and overall growth in domestic spending. In the industrials sector, airport operators were supported by growth in passenger traffic and efforts to diversify revenue.

What detracted from performance?

There were no significant detractors from the Fund’s return during the reporting period.

Factors Affecting Performance [Text Block]

How did the Fund perform last year?

For the reporting period ended August 31, 2025, the Fund returned (3.40)%.
For the same period, the MSCI Emerging Markets Index (Net) returned 16.80% and the MSCI Turkey IMI 25/50 Index (Spliced) returned (2.83)%.

What contributed to performance?

Stocks in the industrials sector were the largest contributor to the Fund’s return during the reporting period. Notably, one of the country’s leading defense contractors advanced following a major government contract for a missile defense system.

What detracted from performance?

Turkish equities have been pressured by political instability and persistently high inflation. The major detractors from the Fund’s return during the reporting period were in the consumer staples sector. A food retailer was negatively impacted following a major administrative fine due to an obstruction of an on-site inspection, while a beer company dropped due to uncertainty over its Russian joint venture. Years of high inflation have eroded consumers purchasing power, negatively impacting consumer durables stocks in the consumer discretionary sector. Chemicals stocks in the materials sector also detracted.

Factors Affecting Performance [Text Block]

How did the Fund perform last year?

For the reporting period ended August 31, 2025, the Fund returned 10.80%.
For the same period, the MSCI USA Index returned 16.45% and the MSCI USA Equal Weighted Index returned 10.94%.

What contributed to performance?

For the reporting period, the largest contributor to the Fund’s performance was the financials sector. Financial services companies, including investment banks and asset managers, benefited from resilient equity markets, rising assets under management, strong trends in wealth management, and high trading volumes. In the information technology sector, application software companies, spanning chip designers, data integrators, and financial software innovators, contributed as they accelerated their artificial intelligence (“AI”)-driven monetization through AI-native tools and platform enhancements. Industrials stocks were supported by robust demand for engines and services in commercial aviation, as well as government support for defense and infrastructure spending.

What detracted from performance?

Healthcare stocks were a modest detractor from the Fund’s performance during the reporting period, pressured by increasing regulatory scrutiny, personnel turmoil, and policy upheaval. Firms that provide life sciences tools and services faced additional headwinds due to government cutbacks and increasing competition from China.

Factors Affecting Performance [Text Block]

How did the Fund perform last year?

For the reporting period ended August 31, 2025, the Fund returned 39.27%.
For the same period, the MSCI ACWI ex USA Index (Net) returned 15.42% and the MSCI Austria IMI 25/50 Index (Net) returned 39.50%.

What contributed to performance?

Despite weak economic growth, Austrian stocks experienced strong returns during the reporting period, helped by foreign capital inflows. The overwhelmingly leading contributor to the Fund’s return were diversified banks in the financials sector, which benefited from strong capital positions, and diversified exposures to central and eastern European countries. Likewise, insurance companies also gained due to exposure to central and eastern European markets, as well as strategic expansions and lower costs from weather-related claims. In the industrials sector, a construction company gained on strong demand in infrastructure and building construction across its European market, including the construction of large data centers, while a leading crane provider benefited as it shifted its revenue and geographical mix.

What detracted from performance?

Real estate stocks were the largest detractor from the Fund’s performance during the reporting period, negatively impacted by worsening financial conditions and weakened demand. Electricity producers in the utilities sector declined amid energy market volatility and geopolitical uncertainties.

Factors Affecting Performance [Text Block]

How did the Fund perform last year?

For the reporting period ended August 31, 2025, the Fund returned 35.27%.
For the same period, the MSCI ACWI ex USA Index (Net) returned 15.42% and the MSCI Italy 25/50 Index (Net) returned 35.54%.

What contributed to performance?

Italy’s economy experienced modest growth during the reporting period driven by domestic demand and supportive fiscal policies. Stock markets rallied, led by the financials sector, which was the largest contributor to the Fund’s return. Diversified banks registered solid performance, driven by strong fee-based revenue and aggressive merger and acquisition activity. Insurance companies also gained, supported by significant premium gains in both life and non-life policies, as well as higher investment returns. In the industrials sector, a company specializing in aerospace, defense, and security benefited from increased European defense spending, robust order intake, solid order backlog, and strategic joint ventures. Additionally, the world’s largest cable maker gained amid strong performance in its transmission and power grid segments, demand for grid investments in the United States and Europe, as well as proposed U.S. tariffs on copper. Through its U.S. business, the firm sources, manufactures, and then sells its copper products within the country, allowing it to mitigate the impact of tariffs.

What detracted from performance?

Automobile manufacturers in the consumer discretionary sector were the largest detractors from the Fund’s return during the reporting period. Carmakers experienced lower shipment volumes across key markets and a product shift toward less profitable vehicles in Europe, while the ongoing threat of U.S. tariffs also weighed on performance.

Factors Affecting Performance [Text Block]

How did the Fund perform last year?

For the reporting period ended August 31, 2025, the Fund returned 6.66%.
For the same period, the MSCI ACWI ex USA Index (Net) returned 15.42% and the MSCI Netherlands IMI 25/50 Index (Spliced) returned 7.37%.

What contributed to performance?

Stocks in the financials sector were the largest contributor to the Fund’s return during the reporting period. Diversified banks benefited from increases in core lending and rising fee income from investment products. In the insurance segment, firms were supported by gains across life and non-life insurance segments, as well as pension reform, which has created growth opportunities for insurance companies. In the consumer discretionary sector, a company that manages global consumer internet companies gained amid strong earnings for its e-commerce portfolio and an attractive share buyback program.

What detracted from performance?

Stocks in the information technology sector were the largest detractors from the Fund’s performance during the reporting period. Notably, an innovative supplier to the semiconductor industry was weighed down by trade tensions and restrictions on trade with China, causing the firm’s management to cut guidance about its expected future financial performance.
