Factors Affecting Performance [Text Block]  

How did the Fund perform last year and what affected its performance?

The reporting period’s market environment was largely driven by speculation about inflation and when and by how much the U.S. Federal Reserve (“the Fed”) and other central banks would begin cutting rates. Alongside this interest rate story was the continuing prospect of an artificial intelligence boom, driving up the values of A.I.-related tech and semiconductor companies. And even though markets moved sideways in Q3 2024 as investors rotated out of growth and tech stocks and back into value and small cap securities, they could not undo the reporting period’s significant influence driven by those mega-cap high-flyers. With the Fed finally cutting rates in September and by 50 bps, the year-long speculation about the timing of the Fed’s directional shift was finally put to rest, and markets ended the year-long period with significant gains and at the highest levels.  On the sector front, Industrials and Utilities were leaders with positive performance coupled with large weights within the fund.

Alongside this interest rate story was the continuing prospect of an Artificial Intelligence boom, driving up the values of A.I.-related tech and semiconductor companies. Risk assets registered positive gains despite pronounced market volatility. Developed markets (DMs) posted positive returns but underperformed emerging markets (EMs), as EM equites performed strongly, supported by the new stimulus in China. India, Taiwan and China were the top drivers of the Fund's return. Power Grid Corporation of India Ltd., NTPC Ltd., and Hero MotoCorp Ltd., were the top contributors to the Fund's performance. Yuexiu Property Company, China Resources Land, and Orbia Advance Corp. were the bottom contributors to the Fund's return.

Factors Affecting Performance [Text Block]  

How did the Fund perform last year and what affected its performance?

All markets in the Asia Pacific region had a strong fourth quarter 2023 showing, with the exception of China, where the lackluster recovery from COVID-19 restrictions as well as real estate woes soured investor sentiment. Of the major emerging markets economies, China was the only underperformer in the first quarter of 2024 as it continued to struggle without any meaningful policy stimulus. However, China did rebound from its January low as the People’s Bank of China cut the five-year loan prime rate to 3.95% from 4.20% in a move to boost economic growth. China’s economic growth stabilized in the second quarter of 2024 but remained constrained, with weak consumer sentiment and ongoing challenges in the property sector. Asia Pacific countries reported positive returns during the third quarter of 2024, with China as one of the top performers. China’s economy bounced back, increasing investor confidence in its resilience. Both onshore and offshore Chinese equities posted positive returns year to date, with Materials, Industrials, and Communication Services sectors leading the way.

Factors Affecting Performance [Text Block]  

How did the Fund perform last year and what affected its performance?

The reporting period’s market environment was largely driven by speculation about inflation and when and by how much the U.S. Federal Reserve ("the Fed") and other central banks would begin cutting rates. REIT performance during the period can be summed up by simply understanding that the asset class is interest rate sensitive and historically a safe haven for investors looking for alternative income streams. Treasury yields declined during the first fiscal quarter and REITs gained over 15% during that period. Then, as the Fed did not pull the trigger on a speculated rate cut in either of the next two quarters, REITs lost value coinciding with those decisions. Finally, as the fiscal year was coming to a close, the Fed finally cut rates in September by 50 basis points and the sector gained another 15%.

Factors Affecting Performance [Text Block]  

How did the Fund perform last year and what affected its performance?

The reporting period’s market environment was largely driven by speculation about inflation and when and by how much the U.S. Federal Reserve (“the Fed”) and other central banks would begin cutting rates. REIT performance during the period can be summed up by simply understanding that the asset class is interest rate sensitive and historically a safe haven for investors looking for alternative income streams. Treasury yields declined during the first fiscal quarter and REITs gained over 15% during that period. Then, as the Fed and other countries such as the Bank of England did not pull the trigger on speculated rate cuts in either of the next two quarters, REITs lost value coinciding with those decisions. Finally, as the fiscal year was coming to a close, the Fed finally cut rates in September by 50 basis points.  This action followed rate cuts in many developed countries during the period and the sector gained another 16% as a result.

Factors Affecting Performance [Text Block]  

How did the Fund perform last year and what affected its performance?

European equities trended higher over the Q4 2023. The Eurozone recorded sharp declines in inflation, raising prospects of rate cuts. Eurozone inflation in November was 2.9%, compared to 10.1% the previous year. During Q1 2024 inflation fell more than expected in March to 2.4%, a result of easing cost in the grocery aisle and as the overall price rises headed down in the two biggest economies – Germany and France. Meanwhile, core inflation, which excludes volatile food and energy costs, eased to 2.9% from 3.1% in February. The MSCI Europe Index (USD) was barely positive at 0.6% during the quarter as concerns around elections in France impacted the overall performance of European equities in Q2 2024. The Bank of England (BoE) refrained from cutting rates in June to exercise caution and keep inflation under control. European equities had a strong quarter during Q3 2024 with top performers in the region being South Africa, Ireland and Belgium while Denmark and the Netherlands were the only underperformers. The European Central Bank (ECB) delivered its second rate cut in September, taking interest rates to 3.5%, while the BoE embarked on its own easing cycle with a 25-bps cut at its August meeting.

Factors Affecting Performance [Text Block]  

How did the Fund perform last year and what affected its performance?

The Fund was up double-digits in Q4 2023. Inflation appeared to be cooling, giving way to exuberant rate cut expectations. The energy sector fell significantly, as concerns around a potential slowdown in global demand weighed on oil prices. During Q1 2024, the U.S. Federal Reserve (“the Fed”) rate cuts got pushed to June, boosting optimism and investor confidence. All major regions, except China, were positive in the quarter, led by Japan and the U.S. Concerns about potential supply disruptions due to ongoing supply cuts by OPEC+ and geopolitical tensions pushed crude prices higher. During Q2 2024. Emerging Markets led among major regions, helped by Taiwan, India, and China. While Growth was very strong in the U.S., it lagged in other regions. Recent decision by the OPEC+ alliance to gradually unwind a complex array of production cuts pushed oil prices lower. Q3 2024 Fund performance was driven by optimism that, in the U.S., inflation has been tamed without a recession. The strongest major country was China. Government action to stimulate the economy and markets led to a surge in Chinese equities. Oil saw its worst quarter so far this year, despite a weaker dollar, elevated geopolitics, and China stimulus.

Factors Affecting Performance [Text Block]  

How did the Fund perform last year and what affected its performance?

The reporting period’s market environment was largely driven by speculation about inflation and when and by how much the U.S. Federal Reserve (“the Fed”) and other central banks would begin cutting rates. Alongside this interest rate story was the continuing prospect of an artificial intelligence boom, driving up the values of A.I.-related tech and semiconductor companies. And even though markets moved sideways in Q3 2024 as investors rotated out of growth and tech stocks and back into value and small cap securities, they could not undo the reporting period’s significant influence driven by those mega-cap high-flyers. With the Fed finally cutting rates in September and by 50 bps, the year-long speculation about the timing of the Fed’s directional shift was finally put to rest, and markets ended the year-long period with significant gains and at the highest levels.

Factors Affecting Performance [Text Block]  

How did the Fund perform last year and what affected its performance?

The reporting period’s market environment was largely driven by speculation about inflation and when and by how much the U.S. Federal Reserve (“the Fed”) and other central banks would begin cutting rates. Alongside this interest rate story was the continuing prospect of an Artificial Intelligence boom, driving up the values of A.I.-related tech and semiconductor companies. And even though markets moved sideways in Q3 2024 as investors rotated out of growth and tech stocks and back into value and small cap securities, they could not undo the reporting period’s significant influence driven by those mega-cap high-flyers. With the Fed finally cutting rates in September and by 50 bps, the year-long speculation about the timing of the Fed’s directional shift was finally put to rest, and markets ended the year-long period with significant gains and at the highest levels. The Fund's 26.20% return for the reporting period outperformed the MSCI EAFE Index's return of 24.80% due to the underperformance of Energy sector stocks. Energy was the only sector to post losses during the reporting period, returning -2.10%, and as a result the Fund's lack of holdings in Energy was the primary contributor to its relative outperformance.

Factors Affecting Performance [Text Block]  

How did the Fund perform last year and what affected its performance?

Equities witnessed a strong start to 2024 as the ‘everything rally’ that began in the fourth calendar quarter of 2023 continued. However these returns moderated in the second calendar quarter of 2024. Business activities, which had seen solid momentum in April and May, slowed down in June. This was driven by weaker expansions of output in the Eurozone, as well as a contraction in Japan. The global economy showed signs of resilience in Q3 2024, with growth in the services sector offsetting weakness in manufacturing. The European Central Bank (ECB) delivered its second rate cut in September 2024, taking interest rates to 3.5%, while the Bank of England (BoE) embarked on its own easing cycle with a 25-bps cut at its August meeting.

Factors Affecting Performance [Text Block]  

How did the Fund perform last year and what affected its performance?

The reporting period’s market environment was largely driven by speculation about inflation and when and by how much the U.S. Federal Reserve (“the Fed”) and other central banks would begin cutting rates. Alongside this interest rate story was the continuing prospect of an Artificial Intelligence boom, driving up the values of A.I.-related tech and semiconductor companies. And even though markets moved sideways in Q3 2024 as investors rotated out of growth and tech stocks and back into value and small cap securities, they could not undo the reporting period’s significant influence driven by those mega-cap high-flyers. With the Fed finally cutting rates in September and by 50 bps, the year-long speculation about the timing of the Fed’s directional shift was finally put to rest, and markets ended the year-long period with significant gains and at the highest levels. The Fund slightly underperformed the MSCI Emerging Markets Index over the reporting period, which returned 26.05%. The exclusion of many stocks from the underperforming Energy sector pushed the Fund towards relative outperformance, but slight differences in the Fund's holdings detracted.

Factors Affecting Performance [Text Block]  

How did the Fund perform last year and what affected its performance?

The reporting period’s market environment was largely driven by speculation about inflation and when and by how much the U.S. Federal Reserve (“the Fed”) and other central banks would begin cutting rates. Alongside this interest rate story was the continuing prospect of an Artificial Intelligence boom, driving up the values of A.I.-related tech and semiconductor companies. And even though markets moved sideways in Q3 2024 as investors rotated out of growth and tech stocks and back into value and small cap securities, they could not undo the reporting period’s significant influence driven by those mega-cap high-flyers. With the Fed finally cutting rates in September and by 50 bps, the year-long speculation about the timing of the Fed’s directional shift was finally put to rest, and markets ended the year-long period with significant gains and at the highest levels. The MSCI Emerging Markets Index produced a 26.05% return during the reporting period. While the quality factor outperformed in Emerging Markets, both value and low volatility factors were weaker. Ultimately, the Fund's underperformance was primarily driven by its exposure to the lowest volatility securities, which produced very weak relative returns.

Factors Affecting Performance [Text Block]  

How did the Fund perform last year and what affected its performance?

The Index posted positive returns year to date as of September 2024. However, the Index underperformed the MSCI World Index for the same time period. The Index experienced positive returns in all four quarters, and it recorded its best return in Q4 2023. 

The reporting period’s market environment was largely driven by speculation about inflation and when and by how much the U.S. Federal Reserve (“the Fed”) and other central banks would begin cutting rates. Alongside this interest rate story was the continuing prospect of an Artificial Intelligence boom, driving up the values of A.I.-related tech and semiconductor companies. And even though markets moved sideways in 3Q24 as investors rotated out of growth and tech stocks and back into value and small cap securities, they could not undo the reporting period’s significant influence driven by those mega-cap high-flyers. With the Fed finally cutting rates in September and by 50 bps, the year-long speculation about the timing of the Fed’s directional shift was finally put to rest, and markets ended the year-long period with significant gains and at the highest levels.

Factors Affecting Performance [Text Block]  

How did the Fund perform last year and what affected its performance?

The global economy showed signs of resilience during the reporting period, with growth in the services sector offsetting weakness in manufacturing. Although global business activity continued to expand, the rate of expansion slowed. There was notable divergence among the main economies: the United States, Japan, and the United Kingdom all experienced growth, while Eurozone, Canada, and China showed signs of stagnation or contraction. The labor market exhibited signs of cooling, and inflation continued to decline. Ongoing geopolitical issues, particularly in Eastern Europe and Asia, continue to create uncertainty, impacting trade and investment flows. Japan, United Kingdom and Canada were the top contributors to the Fund's return. From a sector perspective, financials, industrials, and information technology were the top contributors to the Fund's performance, while energy, real estate and utilities were the bottom contributors. ASML Holding, SAP SE, and Novo Nordisk were the top contributing companies to the Fund's performance. Nestle, BP and Bayer were the bottom contributors to the Fund's return.

Factors Affecting Performance [Text Block]  

How did the Fund perform last year and what affected its performance?

The reporting period’s market environment was largely driven by inflation and when and by how much the U.S. Federal Reserve and other central banks would begin cutting rates. Alongside this interest rate story was the continuing prospect of an artificial intelligence boom, driving up the values of A.I.-related tech and semiconductor companies. Risk assets registered positive gains despite pronounced market volatility. Developed markets posted positive returns but underperformed emerging markets (EMs), as EM equites performed strongly, supported by the new stimulus in China. India, Taiwan and China were the top drivers of the Fund's return. Taiwan Semiconductor, Tencent Holdings, and Alibaba Group were the top contributors to the Fund's performance. Wuxi Biologics, Baidu, and Yum China Holdings were the bottom contributors to the Fund's return.

Factors Affecting Performance [Text Block]  

How did the Fund perform last year and what affected its performance?

European equities trended higher over the Q4 2023. The eurozone recorded sharp declines in inflation, raising prospects of rate cuts. Eurozone inflation in November was 2.9%, compared to 10.1% the previous year. During Q1 2024 inflation fell more than expected in March to 2.4%, a result of easing cost in the grocery aisle and as the overall price rises headed down in the two biggest economies – Germany and France. Meanwhile, core inflation, which excludes volatile food and energy costs, eased to 2.9% from 3.1% in February. The MSCI Europe Index (USD) was barely positive at 0.6% during the quarter as concerns around elections in France impacted the overall performance of European equities in Q2 2024. The Bank of England (BoE) refrained from cutting rates in June to exercise caution and keep inflation under control. European equities had a strong quarter during Q3 2024 with top performers in the region being South Africa, Ireland and Belgium while Denmark and the Netherlands were the only underperformers. The European Central Bank (ECB) delivered its second rate cut in September, taking interest rates to 3.5%, while the BoE embarked on its own easing cycle with a 25-bps cut at its August meeting.

Factors Affecting Performance [Text Block]  

How did the Fund perform last year and what affected its performance?

The reporting period’s market environment was largely driven by speculation about inflation and when and by how much the U.S. Federal Reserve (the "Fed") and other central banks would begin cutting rates. Alongside this interest rate story was the continuing prospect of an artificial intelligence boom, driving up the values of A.I.-related tech and semiconductor companies. And even though markets moved sideways in Q3 2024 as investors rotated out of growth and tech stocks and back into value and small cap securities, they could not undo the reporting period’s significant influence driven by those mega-cap high-flyers. With the Fed finally cutting rates in September and by 50 bps, the year-long speculation about the timing of the Fed’s directional shift was finally put to rest, and markets ended the year-long period with significant gains and at the highest levels.

Factors Affecting Performance [Text Block]  

How did the Fund perform last year and what affected its performance?

The Index rallied 5.9% in Q4 of 2023 as recession concerns eased and growing anticipation of a potential policy easing. Asia Pacific had a strong showing, with the exception of China, where the lackluster recovery from COVID restrictions as well as real estate woes soured investor sentiment. The Index gained 2.7% in Q1 of 2024 as risk assets advanced due to resilient macroeconomic data and strong earnings. However, China was the only underperformer as it continued to struggle without any meaningful policy stimulus. The Index pushed ahead by gaining another 8.7% in Q2 of 2024 driven by favorable performance from risk assets, solid earnings, resilient economy, and favorable inflation data. China’s economy bounced back, increasing investor confidence in its resilience with Materials, Industrials, and Communication Services sectors leading the way. Taiwan benefitted from developments in Artificial Intelligence. The Index delivered the best quarter of the fiscal year by adding another 11.6%. China’s equities rallied as Chinese policymakers announced significant measures to revive and stimulate its economy, majorly through interest rate cuts and government support for the ailing property market, boosting the losing investor confidence.

Factors Affecting Performance [Text Block]  

How did the Fund perform last year and what affected its performance?

Emerging Market small cap equities rallied about 7% in September to end the reporting period up over 20%. The U.S. Federal Reserve 0.50% cut and a series of measures by the Chinese authorities to stimulate growth caused the USD strength to wane, which further added to the momentum of the September rally. Due to the tremendous growth of its economy, India was the best performing country over the reporting period.

Factors Affecting Performance [Text Block]  

How did the Fund perform last year and what affected its performance?

Seven of the twelve months in the reporting period posted positive returns. The reporting period’s market environment was largely driven by speculation about inflation and when and by how much the U.S. Federal Reserve (“the Fed”) and other central banks would begin cutting rates. Alongside this interest rate story was the continuing prospect of an Artificial Intelligence boom, driving up the values of A.I.-related tech and semiconductor companies. And even though markets moved sideways in Q3 2024 as investors rotated out of growth and tech stocks and back into value and small cap securities, they could not undo the reporting period’s significant influence driven by those mega-cap high-flyers. With the Fed finally cutting rates in September and by 50 bps, the year-long speculation about the timing of the Fed’s directional shift was finally put to rest, and markets ended the year-long period with significant gains and at the highest levels.

Factors Affecting Performance [Text Block]  

How did the Fund perform last year and what affected its performance?

Performance of the Fund for the reporting period was driven by a cut in interest rates, easing inflation, and high demand for various metals like copper, zinc and nickel despite higher inventories and mild temperatures. During the reporting period, the Fund's use of their current investment strategies did not cause the Fund's performance to materially deviate from the manager's expectations considering the uncertainty of the markets.

How did the Fund perform last year and what affected its performance?

Performance of the Fund for the reporting period was driven by a cut in interest rates, easing inflation, and positive earnings growth. During the reporting period, the Fund's use of their current investment strategies did not cause the Fund's performance to materially deviate from the manager's expectations considering the uncertainty of the markets.

Factors Affecting Performance [Text Block]  

How did the Fund perform last year and what affected its performance?

The Index started off the fiscal year with the best quarter by posting a gain of 19.2%. In Q4 2023, risk assets gained in value on the back of growing anticipation of a potential policy easing.  In fact, interest rates were cut across fifteen economies in December 2023 including the U.S. Federal Reserve, European Central Bank, and Bank of England. The Index modestly gained 1.5% in Q1 2024 as global economic activity improved, with both services and manufacturing sectors advancing supported by resilient macroeconomic data and strong earnings. The Index lost 1.5% in Q2 2024 mainly driven by concerns around elections in France impacted the overall performance of European equities and contraction and decision to lower its regular bond repurchases in Japan. The Index bounced by in Q3 2024 by gaining 8.1% as the global economy showed signs of resilience with growth in the services sector offsetting weakness in manufacturing.  However, Japan had a mixed quarter. The Japanese Yen, appreciating sharply, saw its strongest run since 2008 resulted in carry trades – a strategy based on borrowing at a low interest rate and using the proceeds to buy higher-yielding currencies or assets – causing a plunge in the Japanese equity market.

Factors Affecting Performance [Text Block]  

How did the Fund perform last year and what affected its performance?

The reporting period’s market environment was largely driven by inflation expectations and when and by how much the U.S. Federal Reserve and other central banks would begin cutting rates. It was a challenging reporting period for commodities and natural resources as growing concerns around the health of the global economy and ample supply weighed on oil prices, which made Energy the worst performing sector in the broad market. Top positive contributors to the Fund's performance were Freeport-McMoRan, Agnico Eagle Mines, and Newmont Corporation. Bottom three contributors were EOG Resources, Cameco Corporation, and Imperial Oil Limited.
