| Factors Affecting Performance [Text Block] | How did the Fund perform last year? Global stocks registered solid gains during the reporting period as investor confidence increased due to several central banks cutting interest rates, a slowdown in pricing pressures, and robust corporate earnings. The European Central Bank cut its primary lending rate in June, and the U.S. Federal Reserve Bank provided strong indications that it would soon lower interest rates. The Reserve Bank of Australia held rates steady, citing persistently high inflation. With inflation still slightly increasing and weak economic growth, the Australian economy was mixed during the reporting period. Though still higher than pre-pandemic levels, job vacancies decreased, and the unemployment rate remained low. What contributed to performance? Stocks in the financials sector strongly contributed to the Fund’s return during the reporting period, led by the banking industry. Following a period of slowing credit growth at the end of 2023, Australian diversified banks benefited from global central bank rate cuts and a strong Australian dollar. Additionally, fears surrounding the Chinese economy drove investors with Asia mandates to invest elsewhere. Consumer discretionary stocks also contributed during the reporting period, most notably in the broadline retail industry. Australia’s largest conglomerate with diversified businesses benefited from cost-conscious consumers opting to shop at its budget department stores amid elevated living costs. What detracted from performance? During the reporting period, energy stocks detracted the most from the Fund’s performance, most notably in the oil and gas exploration and production industry as crude oil prices declined due to lessened demand and geopolitical tensions, Australia’s top independent gas producer fell after a multi-billion-dollar merger with the country’s second-largest independent gas producer collapsed.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? Bolstered by solid corporate earnings and a weak yen, Japanese equities registered significant gains during the reporting period. Helping the country’s economic growth was accelerating inflation, better-than-expected industrial production, and tight labor conditions. As the country moved from deflation to inflation, the Bank of Japan exited its zero-interest rate policy that it had held since 2016, raising its short-term policy rate and suggesting that more hikes would be forthcoming. What contributed to performance? The financials sector was the largest contributor to the Fund’s return during the reporting period. The country’s banking sector gained as the Bank of Japan ended its multi-year zero interest rate policy. The central bank raised rates and reduced its bond buying as it attempted to normalize monetary policy, boosting the net income interest (the difference between the rates banks charge for loans and the rates they pay for deposits) of Japanese banks. Insurance companies also gained on the higher rate regime and anticipated growth. The industrials sector was another source of growth for the Fund, helped by the performance of trading companies and industrial conglomerates. These firms play a vital role in Japan’s economy, operating across various sectors, including commodities, energy, metals, chemicals, consumer goods, logistics, and finance. Information technology stocks also contributed to the Fund’s return, helped by solid performance from technology hardware and semiconductor firms. What detracted from performance? During the reporting period, there were no material detractors from the Fund’s return.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? China’s economic struggles continued during the reporting period, exacerbated by a prolonged downturn in the property market. Sluggish domestic demand has led to deflation and reduced growth prospects, prompting the Chinese government to introduce stimulus packages. As a special administrative region of China, Hong Kong’s equity markets are closely linked to China’s economic performance and policy decisions. The threat of increasing policy tariffs on Chinese imports further deteriorated the economic growth landscape as Canada joined the United States, the European Union, and other countries that have imposed sanctions on Chinese imports. What contributed to performance? Stocks in the utilities sector contributed to the Fund’s performance during the reporting period, benefiting from supportive local policies for clean energy. Hong Kong’s increasing electricity demand also benefited electric utilities companies. What detracted from performance? Financials stocks negatively impacted the Fund’s performance during the reporting period. Slowing economic growth and regulatory changes in China hampered the stock of an American-Hong Kong-based multinational insurance and finance corporation that is also the largest publicly traded life insurance group in the Asia-Pacific region. The operator of the country’s stock exchange declined as trading and listing activities dropped amid China’s economic woes. In the consumer discretionary sector, stocks of Macau-based casinos and gaming stocks declined on new measures to stop unlicensed currency traders. Macau, a Chinese territory, is the world’s largest gambling hub and the only place within China where casino gambling is legal.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? The growing prospect of lower interest rates in the United States helped the performance of emerging market stocks during the reporting period. However, weakening growth in China, geopolitical concerns, and a stronger U.S. dollar weighed on equity performance. Malaysia’s economic growth was supported by strong domestic demand, a stable government, a revitalized interest in tourism, and an expansion of exports. The country also benefited from its robust currency, which outpaced its regional peers during the reporting period. Malaysian officials announced plans to increase technology investments in the country through training of local citizens. What contributed to performance? The financials sector was the strongest contributor to the Fund’s performance during the reporting period. Diversified banking stocks rallied, helped by a surge in foreign inflows and a stable interest rate environment as the Bank of Malaysia held interest rates steady. Additionally, Malaysian banks benefited from investment and trading income, as well as favorable foreign exchange rates. In the utilities sector, the country’s largest electric utility was helped by robust domestic demand, an increased need for data centers, and plans to increase its renewable energy portfolio. Within the construction and engineering industry of the industrials sector, a company that specializes in engineering, property, and infrastructure development around the world was another contributor. This firm is utilizing its next-generation industrial building systems to fast track the delivery of data centers needed for artificial intelligence. What detracted from performance? There were no significant detractors from the Fund’s performance during the reporting period.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? Global stocks registered solid gains during the reporting period as investor confidence increased due to several central banks cutting interest rates, a slowdown in pricing pressures, and robust corporate earnings. The European Central Bank (“ECB”) cut its primary lending rate in June, and the U.S. Federal Reserve Bank provided strong indications that it would soon lower interest rates. As a member of the Eurozone, Spain’s monetary policy, including its policy rate, is determined by the ECB. Driven by strong tourism and low unemployment, Spain’s economy outperformed its peers in the European Union during the reporting period. What contributed to performance? Stocks in the financials sector strongly contributed to the Fund’s return during the reporting period, led by the banking industry. Banks have continued to benefit from high interest rates, leading to a substantial increase in net interest income (the difference between what banks receive from loans and what they pay on deposits). Additionally, household and corporate deposits have grown primarily due to favorable economic conditions within the country. Utilities stocks also benefited performance, most notably among electric utilities that invested heavily in green energy, renewables, and grid infrastructure. What detracted from performance? Stocks in the energy sector detracted the most from the Fund’s performance during the reporting period, most notably in the integrated oil and gas industry. Amid increasing tax pressures on the sector and a windfall tax stemming from surging energy prices, a Spanish energy and petrochemical company announced a plan to potentially merge its North Sea operations with a private-equity-backed company, negatively impacting its stock.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? Global stocks registered solid gains during the reporting period as investor confidence increased due to several central banks cutting interest rates, a slowdown in pricing pressures, and robust corporate earnings. The European Central Bank cut its primary lending rate in June, and the U.S. Federal Reserve Bank provided strong indications that it would soon lower interest rates. Conversely, the Bank of Japan exited its zero-interest rate policy that it had held since 2016, raising its short-term policy rate and suggesting that more hikes would be forthcoming. Inflation in Sweden cooled considerably while unemployment ticked up slightly and growth weakened; this led Riksbank, the Swedish central bank, to cut rates twice during the reporting period while also signaling it will continue to ease monetary policy at a faster-than-anticipated pace. What contributed to performance? Stocks in the industrials sector strongly contributed to the Fund’s performance during the reporting period, led by the capital goods industry. A Swedish multinational industrial company with a wide range of business lines rose after it successfully completed the acquisition of two manufacturers to expand its current product offerings within its scientific vacuum, compressor technique, and helium leak detection divisions. Financials stocks also positively impacted performance. A Swedish investment and holding company was helped by its substantial investment in a profitable telecommunication equipment vendor. What detracted from performance? During the reporting period that ended August 31, 2024, there were no notable detractors from the Fund’s return.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? Global stocks registered solid gains during the reporting period as investor confidence increased due to several central banks cutting interest rates, a slowdown in pricing pressures, and robust corporate earnings. The European Central Bank (“ECB”) cut its primary lending rate in June, and the U.S. Federal Reserve Bank provided strong indications that it would soon lower interest rates. As a member of the Eurozone, Belgium’s monetary policy, including its policy rate, is determined by the ECB. Despite an increasing public deficit, Belgium’s economy proved to be resilient and fast-growing during the reporting period. What contributed to performance? Stocks in the healthcare sector contributed the most to the Fund’s return during the reporting period, led by the pharmaceutical, biotechnology, and life sciences industry. Belgian pharmaceutical companies benefited from continued investment in research and development, successful launches of new high-impact medications, and global demand for innovative healthcare solutions. Consumer staples stocks further contributed to performance, most notably within the beverages industry. Despite ongoing challenges in the global beer market, a dominant Belgium brewer gained as its sales started to rebound following a consumer boycott. What detracted from performance? Stocks in the materials sector detracted from the Fund’s performance during the reporting period, led by the chemicals industry. Reduced demand for electric vehicles hampered companies that produce battery materials and led one firm to delay construction on a new battery plant by up to two years.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? The growing prospect of lower interest rates in the United States helped the performance of emerging market stocks during the reporting period, but geopolitical concerns, weakening growth in China, and a stronger U.S. dollar weighed on equities. Overall, stocks registered solid gains as investor confidence increased due to several central banks cutting interest rates, a slowdown in pricing pressures, and robust corporate earnings. Turkish stocks lagged their emerging market counterparts as the country raised policy rates and enacted extreme measures to deal with sky-high inflation. What contributed to performance? The financials sector was the largest contributor to the Fund’s return during the reporting period. The banking sector benefited as the policy rate ended the reporting period at 50%, increasing net interest income (the difference between the rates banks charge for loans and the rates they pay for deposits). Also contributing was the consumer staples sector, particularly among food retailers and food, beverages, and tobacco stocks. As the Turkish lira depreciated due to the severe policy rate hikes, locally produced consumer staples were more competitive domestically and in export markets. Additionally, the necessity of these goods makes them less vulnerable to economic slowdowns. What detracted from performance? The major detractors from the Fund’s return during the reporting period were in the materials sector, including those that specialize in chemicals. Companies that specialize in metals and mining were pressured by global economic conditions and fluctuating commodity prices. In the industrials sector, rising energy prices and the country’s broader economic challenges, such as inflation and currency volatility, negatively impacted performance.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? The growing prospect of lower interest rates in the United States helped the performance of emerging market stocks during the reporting period, but geopolitical concerns, weakening growth in China, and a stronger U.S. dollar weighed on equities. Overall, global stocks registered solid gains as investor confidence increased due to several central banks cutting interest rates, a slowdown in pricing pressures, and robust corporate earnings. Israel registered solid returns during the reporting period despite an unprecedented strike by Hamas in October 2023. The attack and resulting war have caused bouts of volatility, including steep declines in certain sectors and rallies in others. What contributed to performance? Stocks in the information technology sector were the largest contributors to the Fund’s performance during the reporting period. Israel has spent heavily on research and development and has a reputation for being an innovative leader, particularly within the cybersecurity field. Firms that provide network safety solutions witnessed a considerable jump in their stock prices following a security incident at a rival firm that caused disruptions across industries. Israel also has a burgeoning healthcare industry, helped by a positive regulatory environment and a skilled workforce. During the reporting period, stocks of pharmaceutical, biotech, and life science firms gained amid merger news and generic drug approvals. What detracted from performance? Communication stocks modestly detracted from the Fund’s performance during the reporting period. In the media and entertainment industry, the loss of a significant client adversely affected the stock of an advertising technology firm. In the materials sector, falling fertilizer prices and geopolitical events negatively affected chemicals companies.

Global stocks registered solid gains during the reporting period as investor confidence increased due to several central banks cutting interest rates, a slowdown in pricing pressures, and robust corporate earnings. The European Central Bank (“ECB”) cut its primary lending rate in June, and the U.S. Federal Reserve Bank provided strong indications that it would soon lower interest rates. As a member of the Eurozone, the Netherlands’ monetary policy, including its policy rate, is determined by the ECB. After exiting a technical recession at the start of the reporting period, the Dutch economy has been on solid footing, driven by improved household spending and cooling inflation. What contributed to performance? Stocks in the information technology sector strongly contributed to the Fund’s return during the reporting period, led by the semiconductor materials and equipment industry. Amid ongoing enthusiasm for artificial intelligence, companies that provide the equipment necessary to manufacture crucial semiconductor chips continue to dominate, particularly a Dutch lithography manufacturing company that sells the most advanced chip-making machine. Financial stocks also positively impacted performance, most notably among banks that saw profits and total income boosted by higher-for-longer interest rates and improving business momentum during the reporting period. Stocks in the industrials sector, particularly in the commercial and professional services industry, also aided performance. What detracted from performance? During the reporting period that ended August 31, 2024, there were no notable detractors from the Fund’s return.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? The growing prospect of lower interest rates in the United States helped the performance of emerging market stocks during the reporting period, but geopolitical concerns, weakening growth in China, and a stronger U.S. dollar weighed on equities. Overall, stocks registered solid gains as investor confidence increased due to several central banks cutting interest rates, a slowdown in pricing pressures, and robust corporate earnings. Despite structural issues, including energy supply constraints and unemployment, market optimism persisted, and South African equities registered gains for the reporting period. What contributed to performance? The financials sector was, on average, the largest weighting of the Fund and also the most significant contributor to the Fund’s return during the reporting period. As the South African Reserve Bank kept interest rates high, diversified banks and diversified financial services benefited from rising net interest income (the difference between what banks receive from loans and what they pay on deposits). In the consumer discretionary sector, the growing shift toward e-commerce helped broadline and apparel retailers. Additionally, miners in the materials sector benefited from the soaring price of gold, as the country is home to some of the world’s largest gold mines. What detracted from performance? In the communications sector, a large mobile operator detracted from the Fund’s returns during the reporting period. The firm has a substantial international client base, and the combination of currency devaluations, regional conflicts, and operational challenges significantly impacted the firm’s financial performance and stock price over the reporting period.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? The growing prospect of lower interest rates in the United States helped the performance of emerging market stocks during the reporting period. Asian equity markets benefited from strength in Taiwan and India, but weakening growth in China and a stronger U.S. dollar weighed on performance. Powered by artificial intelligence (“AI”), information technology stocks led the market for the majority of the reporting period. However, market sentiment pivoted toward more defensive sectors late in the reporting period amid growing uncertainty surrounding economic growth, geopolitics, and the upcoming U.S. presidential election. What contributed to performance? The information technology sector in Taiwan was a significant contributor to the Fund’s return during the reporting period. The country’s semiconductor companies are the main suppliers of the chips crucial to phones, cars, and AI applications, leading these chip manufacturers to benefit from heightened global demand and technological advancements. Indian stocks were strong beneficiaries of solid economic growth and positive investor sentiment. India’s financials sector gained due to robust loan growth that helped the performance of diversified banks. Additionally, Indian automobile manufacturers in the consumer discretionary sector gained on strong domestic demand and new vehicle launches. What detracted from performance? Chinese equities were the largest detractors from the Fund’s return. In the consumer discretionary sector, companies that manufacture electric vehicles fell sharply due to increased tariffs on Chinese imports, and fears grew that more countries would do the same. Broadline retailers suffered from an increasingly competitive environment and weak consumer spending.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? Global stocks registered solid gains during the reporting period as investor confidence increased due to several central banks cutting interest rates, a slowdown in pricing pressures, and robust corporate earnings. The European Central Bank (“ECB”) cut its primary lending rate in June, and the U.S. Federal Reserve Bank provided strong indications that it would soon lower interest rates. As a member of the Eurozone, Germany’s monetary policy, including its policy rate, is determined by the ECB. The German economy shrunk during the reporting period, as stagnating economic conditions continued. Lower inflation and increased real wages, however, were bright spots for the country. What contributed to performance? Stocks in the information technology sector contributed the most to the Fund’s return during the reporting period, led by the software and service industry. Enthusiasm over artificial intelligence, increased spending on cybersecurity and cloud computing, and ongoing digitalization efforts in government and the private sector all boosted the sector. The financials sector also contributed to performance, led by the insurance industry. Higher premiums and fewer natural catastrophe claims boosted the property-casual segment during the reporting period. What detracted from performance? Stocks in the healthcare sector detracted the most from the Fund’s performance during the reporting period, most notably within the pharmaceutical, biotechnology, and life sciences industry. Stock in one of the largest pharmaceutical companies in the world fell after it was ordered to pay record damages in ongoing lawsuits against an agricultural biotechnology company it acquired.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? The growing prospect of lower interest rates in the United States helped the performance of emerging market stocks during the reporting period, while weakening growth in China, geopolitical concerns, and a stronger U.S. dollar weighed on returns. While Thailand’s economy has experienced a tourism revival, the country has seen an uneven recovery amid weak export growth, rising living costs, a slump in manufacturing, and high household debt. The country’s slow economic growth weighed on Thailand’s stock markets and its currency, the baht. To boost consumer spending, the Thai government launched a digital wallet plan and distributed approximately $276 per eligible Thai citizen. Around 45-50 million Thai citizens and more than two million vendors are expected to participate in the program. What contributed to performance? Within the communications sector, companies that engage in wireless telecommunications services contributed the most to the Fund’s return during the reporting period. Government policies to drive consumption boosted spending on mobile services. What detracted from performance? Materials stocks were the largest detractor from the Fund’s performance during the reporting period. Within the commodity chemicals industry, stocks were pressured by an increasingly competitive landscape and rising debt levels. Construction materials companies were negatively impacted by a slowdown in the Thai economy, leading to sluggish sales and weak demand. Independent power and renewable electricity producers in the utilities sector detracted amid an environment of slowing economic growth and geopolitical risks. In the consumer discretionary sector, broadline retailers detracted.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? Global stocks registered solid gains during the reporting period as investor confidence increased due to several central banks cutting interest rates, a slowdown in pricing pressures, and robust corporate earnings. The European Central Bank (“ECB”) cut its primary lending rate in June, and the U.S. Federal Reserve Bank provided strong indications that it would soon lower interest rates. As a member of the Eurozone, Italy’s monetary policy, including its policy rate, is determined by the ECB. Cooling inflation, robust wage growth, and rising employment painted a favorable picture for the Italian economy during the reporting period. However, Italy’s growing public debt strained economic growth and impeded private sector investment. What contributed to performance? Stocks in the financials sector strongly contributed to the Fund’s performance during the reporting period, led by the banking industry. Despite a contested windfall tax on the banking sector issued in late 2023, revenue growth among Italian banks remained strong, boosted by significantly higher lending income and a rebound in fee and commission income. Consumer discretionary stocks also contributed to performance, most notably among automobile manufacturers that are supported by strong order books extending well into 2025. What detracted from performance? Stocks in the consumer staples sector detracted the most from the Fund’s return during the reporting period, led by the beverages industry. Following reports that the company is being investigated for unpaid taxes, the stock of an Italian wine and spirits producer slipped as it announced plans to buy a French cognac brand, hurting profit margins.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? The growing prospect of lower interest rates in the United States helped the performance of emerging market stocks during the reporting period, while concerns about demand from China and a strengthening U.S. dollar weighed on returns. Latin American economies were negatively impacted by slowing commodity prices, one of their main exports, and Mexican equities suffered steep losses. The landslide presidential win by Claudia Sheinbaum, leader of Mexico’s ruling party, raised concerns about reduced checks and balances on the Mexican government and downwardly pressured stocks. What contributed to performance? Healthcare stocks modestly contributed to the Fund’s return during the reporting period. This was attributed mainly to a pharmaceutical and personal care company that benefited from strategic moves such as refinancing its long-term debt and acquiring four new brands, further boosting investor confidence. What detracted from performance? The consumer staples sector was the largest detractor from the Fund’s performance during the reporting period. Companies that engage in food retailing and those that provide soft drinks and non-alcoholic beverages and food products were weighed down by higher costs and negative foreign exchange effects due to the appreciation of the Mexican peso. In addition, a major company in the consumer staples merchandise retail industry faced regulatory challenges that negatively impacted its stock price. In the materials sector, stocks of construction materials companies that provide building materials internationally were pressured by weakening demand for cement globally and slowing domestic growth. Industrials stocks, mainly those involved in transportation, were negatively pressured by rising inflation and overall slowing economic growth.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? The growing prospect of lower interest rates in the United States helped the performance of emerging market stocks during the reporting period, although this was countered by weakening growth in China, geopolitical concerns, and a stronger U.S. dollar. Singapore’s central bank kept monetary policy unchanged as the country experienced moderate economic growth and slowing inflation during the reporting period. Singapore equities gained during the reporting period, particularly the financial sector, which saw continued inflows of foreign deposits. What contributed to performance? The financials sector was the leading contributor to the Fund’s return during the reporting period. Singapore has seen strong inflows of wealth due to its political stability, low taxes, and favorable policies toward family offices and trusts, positively impacting the performance of diversified banks. Additionally, banks benefited from improved net interest income (the difference between the rates banks charge for loans and the rates they pay for deposits). In the communication sector, the country’s largest telecommunications operator was helped by strategic initiatives, positive institutional inflows, and an increase in its dividend. Also contributing to performance was the stock of an e-commerce firm that reported earnings that surpassed consensus expectations. What detracted from performance? The industrials sector detracted from the Fund’s performance during the reporting period, most notably the stock of a leading ride-share business. The company’s growth rate was lower than its rivals, leading to disappointing earnings results. Additionally, a company that provides engineering solutions came under pressure following an investigation into possible securities violations.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? Bolstered by solid corporate earnings and a weak yen, Japanese equities registered solid gains during the reporting period. Smaller-capitalization companies underperformed their larger peers. Helping the country’s economic growth was accelerating inflation, better-than-expected industrial production, and tight labor conditions. As the country moved from deflation to inflation, the Bank of Japan exited its zero-interest rate policy that it had held since 2016, raising its short-term policy rate and suggesting that more hikes would be forthcoming. What contributed to performance? The industrials sector was the largest source of growth for the Fund during the reporting period, helped by the performance of building products, construction and engineering, electrical equipment, and machinery companies. Investments in infrastructure and efforts toward decarbonization by the Japanese government helped the firms that provide these services. In the consumer discretionary sector, consumer electronic firms benefited from the rapid evolution of the global camera industry. Information technology stocks also contributed to the Fund’s return, helped by solid performance from semiconductors and semiconductor equipment firms. Stocks of Japan’s chip equipment makers gained from strong demand and upgraded their full-year forecasts as firms continued to invest in artificial intelligence servers. Benefiting from solid growth, companies in the electronic equipment, instruments, and components industry also gained. In the financials sector, the stocks of regional banks increased following the interest rate What detracted from performance? During the reporting period, there were no material detractors from the Fund’s return.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? Global stocks registered solid gains during the reporting period as investor confidence increased due to several central banks cutting interest rates, a slowdown in pricing pressures, and robust corporate earnings. The European Central Bank cut its primary lending rate in June, and the U.S. Federal Reserve Bank provided strong indications that it would soon lower interest rates. The Swiss National Bank cut interest rates twice so far in 2024 and signaled a third cut could come before year-end. With low inflation and unemployment, Switzerland’s economy proved resilient during the reporting period; export activity started to rebound as its currency weakened, but geopolitical conflicts continued to pose risks. What contributed to performance? Stocks in the healthcare sector contributed the most to the Fund’s performance during the reporting period, led by the pharmaceutical, biotechnology, and life sciences industry. The stock of a Swiss drugmaker increased due to strong demand for its cardiovascular, arthritis, and psoriasis drugs. Financials stocks also benefited performance, most notably within the insurance sector, as record performance in life insurance for business and commercial insurance growth drove the profits of a large Swiss insurance company. What detracted from performance? During the reporting period, stocks in the consumer staples sector detracted the most from the Fund’s return, most notably within the packaged food and meats industry. The stock of a Swiss packaged food and beverage giant declined as cost-conscious consumers continued to trade down for more affordable options at the grocery store.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? The growing prospect of lower interest rates in the United States helped the performance of emerging market stocks during the reporting period, but geopolitical concerns, weakening growth in China, and a stronger U.S. dollar weighed on equities. Overall, stocks registered solid gains as investor confidence increased due to several central banks cutting interest rates, a slowdown in pricing pressures, and robust corporate earnings. The Brazilian stock market underperformed other emerging markets over the reporting period, influenced by a combination of economic, political, and global factors. Economic growth, however, rebounded as the impacts of severe flooding were offset by strong consumer spending. What contributed to performance? Amid gains in the energy sector, Brazil’s state-owned oil company was a major contributor to the Fund’s return during the reporting period. The firm announced a hike in gasoline prices and enhanced its exploration opportunities helped by increased capital expenditures. Financials companies also contributed to the Fund’s return, helped by the performance of the country’s banks, which are considered to be among the largest and most advanced in Latin America. While Brazil’s central bank lowered official interest rates during the reporting period, they remained historically high, helping the performance of banks. What detracted from performance? Stocks in the materials sector detracted the most from the Fund’s return during the reporting period. The introduction of cheaper imports as well as sluggish demand from China, one of Brazil’s largest trading partners, weighed on companies that specialize in metals and mining. In the industrials sector, transportation stocks were challenged as the Brazilian government imposed higher taxes, and the country’s largest gasoline firm raised prices.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? Global stocks registered solid gains during the reporting period as investor confidence increased due to several central banks cutting interest rates, a slowdown in pricing pressures, and robust corporate earnings. The European Central Bank cut its primary lending rate in June, while the U.S. Federal Reserve Bank provided strong indications that it would soon lower interest rates. The Bank of Canada cut interest rates in both June and July, citing cooling inflation. Canada’s economy posted solid returns during the reporting period, boosted by the resilience of households and businesses. However, high living costs resulted in decreased consumer discretionary spending, while elevated debt-servicing costs held back business investments, somewhat hindering growth. What contributed to performance? Stocks in the financials sector strongly contributed to the Fund’s return during the reporting period, led by the banking sector. Driven by capital market business strength and a robust investment banking environment, profits at a handful of large Canadian banks surpassed expectations. At the same time, merger and acquisition activity picked up after a long hiatus due to elevated interest rates. Energy stocks also contributed, most notably among oil, gas, and consumable fuels companies. After avoiding a pipeline shutdown, a Canadian pipeline and energy company benefited from rising natural gas demand in North America and a new expansion project. As the artificial intelligence enthusiasm continued, stocks in the information technology sector also contributed. What detracted from performance? During the reporting period that ended August 31, 2024, there were no notable detractors from the Fund’s return.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? Global stocks registered solid gains during the reporting period as investor confidence increased due to several central banks cutting interest rates, a slowdown in pricing pressures, and robust corporate earnings. The European Central Bank cut its primary lending rate in June, and the U.S. Federal Reserve Bank provided strong indications that it would soon lower interest rates. Powered by artificial intelligence (“AI”), information technology stocks led the market for most of the reporting period. However, market sentiment pivoted toward more defensive sectors late in the reporting period amid growing uncertainty surrounding economic growth, geopolitics, and the upcoming U.S. presidential election. What contributed to performance? German stocks, the second-largest weighting in the Fund, contributed the most to the Fund’s performance during the reporting period, led by the information technology sector. Enthusiasm over AI, increased spending on cybersecurity and cloud computing, and ongoing digitalization efforts boosted the sector, most notably within the software and services industry. The German financials sector also contributed to performance, led by insurance companies. Stocks in the Netherlands benefited returns, most notably in the semiconductors and semiconductor equipment industry within the information technology sector. Despite fears of potential export restrictions to China, the stock of Europe’s largest technology firm that manufactures the machines used to build computer chips continued to rise. What detracted from performance? During the reporting period, stocks in Ireland detracted from the Fund’s performance, most notably in the materials sector. The stock of a provider of building materials solutions declined after it transitioned its primary listing to the New York Stock Exchange, causing frustration among some shareholders.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? The growing prospect of lower interest rates in the United States helped the performance of global equities during the reporting period. The Australian economy was mixed during the reporting period with persistent inflation and weak economic growth. The country’s held rates steady citing persistently high inflation, which strengthened the Australian dollar. Despite starting the reporting period in a technical recession, New Zealand posted positive returns as economic conditions slightly improved due in part to a tourism recovery. As a special administrative region of China, Hong Kong’s equity markets are closely linked to China’s economic performance and policy decisions. What contributed to performance? Australian stocks overwhelmingly contributed to the Fund’s return. Diversified banks in the financials sector were positively impacted by solid lending growth and strong earnings reports. Diversified capital markets, financial exchanges and data stocks also contributed to the Fund’s return. In the consumer discretionary sector, a diversified conglomerate that owns several well-known retail stores benefited from strong sales, leading the firm to increase its dividend. Singapore has seen strong inflows of wealth due to its political stability, low taxes, and favorable policies toward family offices and trusts, positively impacting financials stocks. What detracted from performance? Conversely, financials stocks in Hong Kong negatively impacted the Fund’s performance during the reporting period. Slowing economic growth and regulatory changes in China hampered the stock of an American-Hong Kong-based multinational insurance and finance corporation that is also the largest publicly traded life insurance group in the Asia-Pacific region.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? The growing prospect of lower interest rates in the United States helped the performance of emerging market stocks during the reporting period, while concerns about demand from China and a strengthening U.S. dollar weighed on returns. Across regions, Asian equity markets benefited from strength in Taiwan and India, but weakening growth in China weighed on performance. Latin American economies were negatively impacted by slowing commodity prices, one of their main exports. Despite geopolitical concerns, many countries in Eastern Europe saw moderate economic growth. The global macro backdrop was increasingly unstable during the reporting period, and a multitude of elections added to uncertainty. As inflationary pressures eased, the central banks of emerging and developed countries began lowering interest rates. What contributed to performance? Indian stocks were the leading contributors to the Fund’s performance. Among healthcare stocks, pharmaceuticals firms gained as the country is a leader in global drug manufacturing and innovation. This is particularly evident in the generic and vaccine segments as Indian pharmaceuticals firms provide cost efficiencies and high-quality solutions. Additionally, IT consulting companies in the information technology sector that help companies identify opportunities and develop corporate strategies involving artificial intelligence benefited. What detracted from performance? Mexican stocks were among the leading detractors from the Fund’s return during the reporting period. A major company in the consumer staples merchandise retail industry faced regulatory challenges that negatively impacted its stock price. Turkish stocks also detracted, as the country’s efforts to tackle soaring inflation eroded corporate profits.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? Global stocks registered solid gains during the reporting period as investor confidence increased due to several central banks cutting interest rates, a slowdown in pricing pressures, and robust corporate earnings. The European Central Bank cut its primary lending rate in June, and the U.S. Federal Reserve Bank provided strong indications that it would soon lower interest rates. Conversely, the Bank of Japan exited its zero-interest rate policy that it had held since 2016, raising its short-term policy rate and suggesting that more hikes would be forthcoming. Powered by artificial intelligence (“AI”), information technology stocks led the market for most of the reporting period. However, market sentiment pivoted toward more defensive sectors late in the reporting period amid growing uncertainty surrounding economic growth, geopolitics, and the upcoming U.S. presidential election. What contributed to performance? Stocks in the United States significantly contributed to the Fund’s return during the reporting period. Among U.S. stocks, the information technology sector was the largest contributor to the Fund’s performance, as firms seen as potential beneficiaries of AI gained. U.S. semiconductors and semiconductor equipment companies were a leading source of strength, as these companies produce the specialty chips needed to power AI. Japanese stocks also contributed to performance, particularly in the industrials industry. The stock of a Japanese manufacturing corporation with several business lines increased as it completed its lengthy restructuring process to focus on AI, power grids, and data centers. What detracted from performance? During the reporting period, there were no notable detractors from the Fund’s performance.

What contributed to performance? Indian stocks were the largest contributors to the Fund’s performance during the reporting period. All sectors gained as India’s economy has shown considerable strength, supported by infrastructure investment, a buoyant manufacturing sector, improving unemployment, and inflation beginning to return to the Reserve Bank of India’s target rate. Investor enthusiasm for AI elevated Taiwanese stocks, particularly those that produce the semiconductors needed to process the large quantities of data generated by AI applications. What detracted from performance? Chinese equities were the largest detractors from the Fund’s return. Stocks of electric vehicle makers fell sharply due to increased tariffs on Chinese imports from the European Union and the United States, and fears grew that more countries would do the same. Financials stocks were negatively impacted as the country’s economic and property woes increased the amount of non-performing loans on the books of diversified banks.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? The growing prospect of lower interest rates in the United States helped the performance of global markets during the reporting period, including frontier markets. Despite geopolitical concerns, many countries in Eastern Europe saw moderate economic growth. What contributed to performance? Stocks in Kazakhstan led the Fund’s return for the reporting period. Favorable international market conditions and growing financial technology initiatives helped stimulate capital inflows into financials stocks. Stocks in Romania also contributed, as the country’s nascent stock market benefited from an improved economic outlook and growing trade volumes. Energy stocks gained on increased demand for energy resources and efforts to switch to renewable energy, as the country strives to meet the European Union’s decarbonization goals. Additionally, a project to develop an offshore natural gas project in the Black Sea positively impacted two companies in the oil, gas, and consumables sector. What detracted from performance? Vietnamese stocks were the largest detractors from the Fund’s return during the reporting period. Real estate stocks have faced significant challenges as liquidity crises, debt pressure, defaults, and scandals all led to a decline in market confidence. Nigerian stocks also negatively impacted the Fund’s performance, as the country suffered from sluggish growth and high inflation. Nigeria’s top cement manufacturer declined amid loosened currency regulations. The fallout from a devalued naira (Nigeria’s currency) spread to the communications sector and caused foreign exchange losses in one of Africa’s largest telecoms operators.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? Global agricultural producers faced severe pricing pressures during the reporting period amid weather-related events, increased production, and competitive pricing. Prices of wheat and maize peaked following the war between Russia and Ukraine but have since leveled off. The global fertilizer industry came under pressure amid geopolitical risks, export restrictions from China, and lower-than-expected crop prices. What contributed to performance? The Indian consumer staples sector contributed to the Fund’s performance during the reporting period. Companies that engage in the packaged foods and meats industry experienced a transformation due to shifting consumer preferences. These firms benefited from the country’s high growth, rise in disposable income, and increasing urbanization. The materials sector also contributed as India’s growing population and increased food consumption have added to the demand for fertilizers. What detracted from performance? The United States was the largest detractor from the Fund’s return during the reporting period as the country suffered from agriculture trade deficits. A strengthening U.S. dollar negatively impacted exports, while high labor costs raised the cost of producing specialty crops domestically, hampered companies in the agricultural products and services industry. Materials stocks in Canada also detracted as the world’s largest fertilizer company suffered from challenging market conditions in Brazil as well as sluggish demand. In Turkey, stocks suffered as the government attempted to fight soaring inflation and an overvalued lira (the country’s currency). In addition, firms in the agricultural products and services industry faced livestock shortages, wheat production declines, and the impacts of climate change.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? Global stocks registered solid gains during the reporting period as investor confidence increased due to several central banks cutting interest rates, a slowdown in pricing pressures, and robust corporate earnings. The European Central Bank (“ECB”) cut its primary lending rate in June, and the U.S. Federal Reserve Bank provided strong indications that it would soon lower interest rates. As a member of the Eurozone, Austria’s monetary policy, including its policy rate, is determined by the ECB. Tight financial conditions, labor shortages, and decreasing domestic demand hampered economic conditions in Austria during the reporting period. However, slowing inflation and central bank monetary policy easing in Europe made way for slight economic growth. What contributed to performance? Stocks in the financials sector strongly contributed to the Fund’s return during the reporting period, led by the banking industry. Declining inflation, increased economic stabilization, and higher net interest rates boosted Austrian bank profits. Real estate stocks also contributed to performance, most notably among real estate operating companies. The stock of a commercial real estate company increased following strong operating development due to higher-yield retail properties and robust rental income growth thanks to solid occupancy rates. What detracted from performance? Stocks in the information technology sector detracted the most from the Fund’s performance during the reporting period, most notably in the technology hardware and equipment industry. An Austrian technology company that specializes in high-end circuit boards was negatively impacted by weakened demand in key markets such as mobile devices and a broader slowdown in the global electronics sector.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? Global stocks registered solid gains during the reporting period as investor confidence increased due to several central banks cutting interest rates, a slowdown in pricing pressures, and robust corporate earnings. The global macro backdrop was increasingly unstable during the reporting period and a multitude of elections added to uncertainty. As inflationary pressures eased, the central banks of emerging and developed markets began lowering interest rates. In the United States, investors rotated out of the information technology sector and into healthcare, communication services, and utilities, all sectors that are historically less volatile. What contributed to performance? Stocks in the United States contributed the most to the Fund’s return during the reporting period. The U.S. healthcare sector advanced notably, particularly within the biotechnology industry as new drug treatments drove gains in the sector. One large U.S. biopharmaceutical company advanced due to the development of a non-opioid drug that treats acute neuropathic pain, currently in late-stage clinical trials; another gained after it received Food and Drug Administration approval for its new treatment for children with genetic high cholesterol. The financials sector also contributed to the Fund’s return, particularly among insurance companies. Additionally, Indian stocks gained, led by the information technology sector. An information technology consultancy firm benefited after it announced a global strategic partnership with a U.S. cybersecurity technology company that will leverage artificial intelligence to transform and modernize enterprise cybersecurity. What detracted from performance? During the reporting period, there were no notable detractors from the Fund’s performance.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? The growing prospect of lower interest rates in the United States helped the performance of emerging market stocks during the reporting period. South Korean equities posted modest returns amid moderating inflation, but concerns remain about slowing jobs growth. The Bank of Korea kept the monetary policy unchanged during the reporting period. Powered by artificial intelligence, information technology stocks led the market for the majority of the reporting period. However, market sentiment pivoted toward more defensive sectors late in the reporting period amid growing uncertainty surrounding economic growth, geopolitics, and the upcoming U.S. presidential election. What contributed to performance? South Korea’s financials sector was the largest contributor to the Fund’s performance during the reporting period. Stocks of diversified banks moved higher following regulatory efforts to speed up corporate reforms, boost shareholder profits, and increase tax benefits. In healthcare, pharmaceuticals and biotechnology firms benefited from acquisitions, positive clinical trials, and drug approvals. What detracted from performance? The materials sector detracted the most from the Fund’s performance during the reporting period. In the commodity chemicals industry, companies that manufacture batteries declined due to slowing global demand for electric vehicles and overproduction by China, leading some manufacturers to cut prices. In the metals and mining industry, steelmakers were negatively impacted by higher raw material prices and reduced demand. In the industrials sector, slowing demand for electric vehicles and a supply glut for rechargeable batteries spread to electrical equipment stocks, causing them to decline.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? The growing prospect of lower interest rates in the United States helped the performance of emerging market stocks during the reporting period, however, weakening growth in China, geopolitical concerns, and a stronger U.S. dollar weighed on returns. Taiwan’s status as the center of semiconductor manufacturing has attracted significant foreign investment and technological advancements, pushing the country’s equity markets to new all-time highs. The strength of the technology sector, powered by artificial intelligence (“AI”) and the semiconductor firms that manufacture the chips that power AI, helped Taiwanese equities gain during the reporting period. What contributed to performance? Information technology stocks overwhelmingly contributed to the Fund’s return. Gains were dominated by firms in the semiconductor segment, predominately from the country’s largest firm and one of the world’s largest semiconductor companies. In addition to their use in AI applications, semiconductors are used in smartphones, laptops, automotives, and many other industries. Taiwan’s financials sector also contributed to the Fund’s performance. Diversified banks were supported by a high retail deposit base, recovering corporate lending, and solid wealth management fees. Companies within life and health insurance also gained. What detracted from performance? Detracting from the Fund’s return during the reporting period were stocks within the materials sector. Within the commodity chemicals industry, the stock of the country’s largest industrial conglomerate suffered from soft petrochemical demand, a weak recovery in China, and foreign exchange losses.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? Global stocks registered solid gains during the reporting period as investor confidence increased due to several central banks cutting interest rates, a slowdown in pricing pressures, and robust corporate earnings. Geopolitical tensions, increased buying from central banks, and rising demand helped gold prices steadily increase during the reporting period, reaching several new all-time highs. A slowing U.S. dollar, anticipation of rate cuts by the U.S. Federal Reserve Bank, and the upcoming U.S. presidential election have helped drive up the price of gold as investors seek the metal’s safe-haven qualities. What contributed to performance? Stocks in Canada were the largest contributor to the Fund’s return. As the world’s fourth-largest gold producer, Canada is home to numerous natural resources and benefits from established and transparent mining-friendly regulations. Gold miners surged during the reporting period as the price of gold was buoyed by increased demand, particularly buying by central banks, and expectations for lower interest rates. In the United States, one of the world’s largest gold miners contributed to the Fund’s return as the firm benefited from favorable market conditions and improved profits. South African gold miners were positively impacted by increased output of the precious metal, better grades, and the rally in the gold price. What detracted from performance? Indonesian stocks detracted from the Fund’s return during the reporting period. The country’s state miner declined amid allegations that the company counterfeited gold.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? Global stocks registered solid gains during the reporting period as investor confidence increased due to several central banks cutting interest rates, a slowdown in pricing pressures, and robust corporate earnings. The European Central Bank (“ECB”) cut its primary lending rate in June, and the U.S. Federal Reserve Bank provided strong indications that it would soon lower interest rates. As a member of the Eurozone, France’s monetary policy, including its policy rate, is determined by the ECB. Despite a hefty deficit and growing debt, the French economy had a better-than-expected start to the year. However, snap Parliamentary elections and uncertainty surrounding both parties’ plans to reduce the deficit caused volatility late in the reporting period. What contributed to performance? Stocks in the industrials sector contributed the most to the Fund’s performance during the reporting period, led by the capital goods industry. Stock in a French multinational energy management and digital automation company rose after it upgraded its cloud-based energy management platform that is used to help companies monitor, track, and standardize their sustainability efforts. Financial stocks further contributed to performance, most notably among insurance companies. What detracted from performance? Consumer discretionary stocks detracted the most from the Fund’s returns during the reporting period, led by the consumer durables industry. The stock of the world’s largest luxury goods conglomerate fell as consumers continued to rein in spending on luxury items amid challenging economic conditions including rising prices and high interest rates.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? The Reserve Bank of India held rates steady during the reporting period, helping inflation return to the central bank’s target rate. While Indian equities gained considerably, stocks faced volatility after Prime Minister Narendra Modi’s unexpected Parliamentary majority loss. China’s prolonged property market decline continued, and sluggish domestic demand led to deflation and reduced growth prospects. The major policy interventions enacted by the government helped to ease investor concerns, but sentiment remained cautious. The Brazilian stock market underperformed, influenced by a combination of economic, political, and global factors. Smaller companies were further impacted by high interest rates and inflation, which constrained consumer spending and investment. What contributed to performance? Indian equities were the main driver behind the Fund’s performance during the reporting period. India’s economy has shown considerable strength, supported by infrastructure investment, a buoyant manufacturing sector, and improving unemployment. In the financials sector, robust loan growth helped the performance of diversified banks. In the industrials sector, aerospace and defense companies benefited from a growing demand for domestic air travel and government initiatives encouraging innovation in space ventures. What detracted from performance? China’s economic struggles continued during the reporting period, causing it to detract from the Fund’s return. In the consumer discretionary sector, stocks of electric vehicle makers fell sharply as the United States, the European Union, and Latin America increased tariffs on Chinese imports, and fears grew that more countries would do the same. Healthcare stocks were pressured as the United States moved closer to passing the U.S. Biosecure Act, which would prohibit federal funding for companies that have commercial arrangements with certain Chinese biotechnology firms.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? The growing prospect of lower interest rates in the United States helped the performance of emerging market stocks during the reporting period, while concerns about demand from China and a strengthening U.S. dollar weighed on returns. Asian equity markets benefited from strength in Taiwan and India, but weakening growth in China weighed on performance. Latin American economies were negatively impacted by slowing commodity prices, one of their main exports. Despite geopolitical concerns, many countries in Eastern Europe saw moderate economic growth. The global macro backdrop was increasingly unstable during the reporting period although pockets of optimism were evident. The restrictive rate environment benefited higher quality companies, and in emerging markets, strong momentum was driven by growth prospects. What contributed to performance? Indian stocks were among the largest contributors to the Fund’s return during the reporting period. In the industrials sector, aerospace and defense companies benefited from a growing demand for domestic air travel and government initiatives to encourage innovation in space ventures. In the financials sector, robust loan growth helped the performance of diversified banks. Taiwanese stocks also contributed to the Fund’s return, dominated by firms in the semiconductor segment, predominately from the country’s largest firm and one of the world’s largest semiconductor companies. In addition to their use in artificial intelligence applications, semiconductors are used in smartphones, laptops, automotives, and many other industries. What detracted from performance? Mexican stocks were a modest detractor from the Fund’s performance during the reporting period. Diversified banks within the financials sector were hampered by the unexpected victory of Claudia Sheinbaum, as many investors feared her policies would negatively impact Mexican equities.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? The growing prospect of lower interest rates in the United States helped the performance of emerging market stocks during the reporting period, but geopolitical concerns, weakening growth in China, and a stronger U.S. dollar weighed on equities. Overall, stocks registered solid gains as investor confidence increased due to several central banks cutting interest rates, a slowdown in pricing pressures, and robust corporate earnings. However, Chile’s stock market retreated during the reporting period, negatively pressured by economic weakness in China, Chile’s largest trading partner. Conversely, rising copper prices, the country’s largest export, helped the Chilean economy. Following a four-year freeze on electricity prices that resulted in billions of dollars of debt, the country began to gradually raise these rates, a move that looks to ease working capital constraints for energy projects. What contributed to performance? Financial stocks contributed the most to the Fund’s performance during the reporting period. Diversified banks reported solid earnings and benefited from signs of recovery in the Chilean economy. In the consumer discretionary sector, a broadline retailer benefited from cost-cutting measures as well as an expansion into Peru. What detracted from performance? Industrials stocks were among the largest detractors from the Fund’s return during the reporting period. In the electrical components and equipment industry, one of the world’s largest lithium producers was negatively impacted by a significant price drop of the metal used in batteries. In the utilities sector, a widespread storm that caused severe power outages resulted in a government review of an electricity firm’s concession, causing a severe drop of the firm’s stock price as well as the stock of its parent company.

The growing prospect of lower interest rates in the United States helped the performance of emerging market stocks during the reporting period. Asian equity markets benefited from strength in Taiwan and India, but weakening growth in China weighed on performance. Latin American economies were negatively impacted by slowing commodity prices, one of their main exports. Despite geopolitical concerns, many countries in Eastern Europe saw moderate economic growth. Powered by artificial intelligence (“AI”), information technology stocks led the market for the majority of the reporting period. However, market sentiment pivoted toward more defensive sectors late in the reporting period amid growing uncertainty surrounding economic growth, geopolitics, and the upcoming U.S. presidential election. What contributed to performance? Indian stocks were the largest contributors to the Fund’s performance. Indian equities have been supported by solid economic growth and strong domestic fund inflows. Companies that provide electrical components and equipment in the industrials sector were a source of strength, benefiting from the country’s drive to increase access to electricity. In Taiwan, companies that manufacture the semiconductors needed to process the large quantities of data generated by AI applications contributed. What detracted from performance? Chinese equities detracted the most from the Fund’s return during the reporting period as the country continued to face economic struggles. In the real estate sector, stocks were challenged by the country’s ongoing property crisis. Healthcare stocks faced further pressure due to concerns over the U.S. Biosecure Act, which would prohibit federal funding for companies that have commercial arrangements with certain Chinese biotechnology firms.

The Fund sought to track the investment results of an index composed of Russian equities, as represented by the MSCI Russia 25/50 Index (the “Index”). Effective June 1, 2022, the Index was discontinued by the index provider, MSCI, Inc. Due to the discontinuation of the Fund’s underlying index and ongoing restrictions relating to Russian securities, the Fund will be unable to meet its investment objective. The Fund is in the process of liquidating its assets and winding up its business pursuant to a plan of liquidation. During the period, the Fund was able to sell certain investments, which were previously being fair valued at a nominal value like all other local Russian equities and Russian exposed ADR and GDR securities, and received interest on its money market fund holdings.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? The growing prospect of lower interest rates in the United States helped the performance of emerging market stocks during the reporting period, while concerns about demand from China and a strengthening U.S. dollar weighed on returns. Asian equity markets benefited from strength in Taiwan and India, but weakening growth in China weighed on performance. Latin American economies were negatively impacted by slowing commodity prices, one of their main exports. And, despite geopolitical concerns, many countries in Eastern Europe saw moderate economic growth. Powered by artificial intelligence (“AI”), information technology stocks led the market for the majority of the reporting period. However, market sentiment pivoted toward more defensive sectors late in the reporting period amid growing uncertainty surrounding economic growth, geopolitics, and the upcoming U.S. presidential election. What contributed to performance? Information technology stocks from Taiwan were the largest contributors to the Fund’s performance during the reporting period. Gains were dominated by firms in the semiconductor segment, predominately from the country’s largest firm and one of the world’s largest semiconductor companies. In addition to their use in AI applications, semiconductors are used in smartphones, laptops, automotives, and many other industries. Indian stocks also strongly contributed to the Fund’s performance during the reporting period. All sectors gained as India’s economy has shown considerable strength, supported by infrastructure investment, a buoyant manufacturing sector, improving unemployment, and inflation beginning to return to the Reserve Bank of India’s target rate. What detracted from performance? Mexican stocks were a modest detractor from the Fund’s performance during the reporting period, particularly the consumer staples sector. Companies in the food, beverage, and tobacco industry were weighed down by higher costs and negative foreign exchange effects due to the appreciation of the Mexican peso.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? Global stocks registered solid gains during the reporting period as investor confidence increased due to several central banks cutting interest rates, a slowdown in pricing pressures, and robust corporate earnings. Metals and mining producer companies faced several challenges during the reporting period, including geopolitical risks, volatile exchange rates, unpredictable demands, and rising costs. China is one of the world’s largest consumers of many metals, and continued weakness in the country’s economy has weighed on metals and mining producers. The country remains the world’s largest producer and consumer of steel. What contributed to performance? Steel companies in India contributed the most to the Fund’s return during the reporting period, benefiting from robust demand. India is the world’s second-largest producer of crude steel, as well as a healthy consumer, driven by the Indian government’s spending on infrastructure. In the United Kingdom, diversified miners rose. Notably, a British-Australian miner that is a major producer of iron ore gained amid an environment of improved supply and easing commodity, diesel, and natural gas prices. What detracted from performance? Metal and mining companies in Korea were the biggest detractors from the Fund’s performance during the reporting period. The stock prices of steel firms were hampered by slowing domestic construction demand, and as excessive output from China drove down steel prices. Australian companies engaged in diversified metals also detracted from the Fund’s return, weighed down as lithium and cobalt prices trended lower.

What detracted from performance? Chinese equities were the largest detractors from the Fund’s return. Stocks of electric vehicle makers fell sharply due to increased tariffs on Chinese imports from the European Union and the United States, and fears grew that more countries would do the same. Financials stocks were negatively impacted as the country’s economic and property woes increased the amount of non-performing loans on the books of diversified banks.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? Global stocks registered solid gains during the reporting period as investor confidence increased due to several central banks cutting interest rates, a slowdown in pricing pressures, and robust corporate earnings. Silver’s many industrial applications, including batteries, LED chips, and semiconductor chips, helped push the metal’s physical price higher. Due to its conductivity properties, silver is also a critical component of solar panels and wind turbines, as well as in the control rods of nuclear reactors. Fluctuations in interest rates and demand from the green energy sector, as well as general uncertainty in the broader economy also benefited the price of silver. What contributed to performance? Stocks in Canada were the largest contributor to the Fund’s return. Canada is home to numerous natural resources and benefits from established and transparent mining-friendly regulations. Gold and silver miners advanced during the reporting period as the prices of these metals hit all-time highs, buoyed by hopes for interest rate cuts in the United States and stimulus measures in China. In the United States, the performance of the largest silver mining company in the country benefited from the metal’s potential in the renewables sector. In the United Kingdom, a London-based precious metals miner advanced on an increase in gold production at its key mine in Brazil. What detracted from performance? Companies in Mexico’s materials sector were the largest detractors from the Fund’s return during the reporting period. The stock of one of the country’s biggest industrial groups suffered as higher production costs and a strike called by the national mining union negatively impacted operating profits.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? Global stocks registered solid gains during the reporting period as investor confidence increased due to several central banks cutting interest rates, a slowdown in pricing pressures, and robust corporate earnings. Commodity prices were volatile. While oil prices rose during the first half of the reporting period, they steadily trended lower, impacted by ongoing geopolitical tensions and questions about demand from China, even as OPEC + extended oil production cuts. Amid high inventories and a historically warm Northern Hemisphere winter, natural gas prices declined throughout much of the reporting period. A heatwave in the early summer led to a spike in natural gas prices and offset some of the declines. What contributed to performance? The United States energy sector was the largest contributor to the Fund’s return during the reporting period. Among companies in the oil, gas, and consumable fuels industry, a major exploration and production company contributed after it was acquired by another energy firm. Additionally, the stock of an oil refiner advanced after reporting an increase in profits. In India, multinational conglomerates focusing on oil, gas, exploration, and production advanced on a favorable refining and economic outlook. What detracted from performance? Stocks in Australia that engage in oil, gas, exploration, and production detracted from the Fund’s return during the reporting period. In addition to rising supply and falling demand, the stock of one firm declined on continued demand concerns and the company’s decision to pursue two acquisitions in the United States.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? The growing prospect of lower interest rates in the United States helped the performance of emerging market stocks during the reporting period. Asian equity markets benefited from strength in Taiwan and India, but weakening growth in China weighed on performance. Latin American economies were negatively impacted by slowing commodity prices, one of their main exports. Despite geopolitical concerns, many countries in Eastern Europe saw moderate economic growth. Powered by artificial intelligence (“AI”), information technology stocks led the market for the majority of the reporting period. However, market sentiment pivoted toward more defensive sectors late in the reporting period amid growing uncertainty surrounding economic growth, geopolitics, and the upcoming U.S. presidential election. What contributed to performance? Indian stocks were the largest contributors to the Fund’s performance during the reporting period. All sectors gained as India’s economy has shown considerable strength, supported by infrastructure investment, a buoyant manufacturing sector, improving unemployment, and inflation beginning to return to the Reserve Bank of India’s target rate. Investor enthusiasm for AI elevated Taiwanese stocks, particularly those that produce the semiconductors needed to process the large quantities of data generated by AI applications. What detracted from performance? Chinese equities were the largest detractors from the Fund’s return. Stocks of electric vehicle makers fell sharply due to increased tariffs on Chinese imports from the European Union and the United States and fears grew that more countries would do the same. In the consumer staples sector, food, beverage, and tobacco companies were hampered by slower consumer spending, negatively impacting premier alcoholic beverage stocks.
