| Factors Affecting Performance [Text Block] | MANAGEMENT’S DISCUSSION OF FUND PERFORMANCE For the 12-month reporting period ended October 31, 2024, the fund returned 29.16%. The MSCI Emerging Markets Index (Net), which serves as the fund’s regulatory index and provides a broad measure of market performance, returned 25.32% 1 . The fund does not seek to track the regulatory index. On June 21, 2024, the fund transitioned from generally investing in securities that are included in the Russell RAFI™ Emerging Markets Large Company Index (Net) which returned 31.28% 1 to generally investing in securities that are included in the RAFI Fundamental High Liquidity Emerging Markets Index (Net). The RAFI Fundamental High Liquidity Emerging Markets Index (Net) has not been in operation for a full year, and therefore has no performance data to present. The Fundamental Emerging Markets Spliced Index returned 31.40%. Fair valuation 2 of the fund’s holdings detracted from the fund’s relative performance. Top detractors from total return: ■ Securities from the Czech Republic, including CEZ AS ■ While there were no additional markets that detracted from the total return of the fund, securities from Hong Kong were the smallest contributors to total return Top contributors to total return: ■ Taiwanese securities, including Taiwan Semiconductor Manufacturing Co. Ltd. ■ Chinese securities Portfolio holdings may have changed since the report date. 1 The net version of the index reflects reinvested dividends net of withholding taxes but reflects no deductions for expenses or other taxes. 2 Fair valued by management using significant unobservable inputs in accordance with procedures approved by the fund’s Board of Trustees. | |
