Factors Affecting Performance [Text Block] | How Did the Fund Perform Last Year? What Affected the Fund's Performance? During the 12-month period ended June 30, 2024, all share classes of the Fund underperformed the benchmark before sales charges. Both security selection and sector allocation detracted from performance, relative to the benchmark. Overall security selection detracted the most, particularly selection within consumer discretionary and health care, while selection within communication services and materials contributed. Sector allocation also detracted as losses from underweights to consumer discretionary and health care offset gains from overweights to communication services and materials. Country positioning (a result of bottom-up security analysis combined with fundamental research) was negative; losses from an overweight to China were partially offset by contributions from an overweight to Denmark. The Fund did not utilize derivatives during the six- or 12-month periods. | |

During the 12-month period ended June 30, 2024, the Fund underperformed the benchmark before sales charges. Both security selection and sector allocation detracted from performance, relative to the benchmark. Security selection detracted most, led by selection within healthcare, technology and industrials. Regarding sector allocation, contributions from an overweight to technology and an underweight to consumer discretionary were offset by an underweight to communication services and an overweight to health care. From a theme perspective, Health and Empowerment detracted, while Climate contributed. The Fund did not utilize derivatives during the six- or 12-month periods. | |

Factors Affecting Performance [Text Block] | How Did the Fund Perform Last Year? What Affected the Fund's Performance? During the 12-month period ended June 30, 2024, Advisor Class shares of the Fund outperformed the benchmark before sales charges. Overall sector allocation and security selection contributed to performance, relative to the benchmark. Security selection within industrials and health care contributed the most, while selection within communication services and financials detracted. In terms of sector allocation, overweights to financials and technology added to gains and offset losses from an underweight to health care and an overweight to energy. Country allocation (a result of bottom-up security analysis combined with fundamental research) detracted, led by an underweight to Japan; an underweight to France contributed. The Fund used derivatives in the form of currency forwards for hedging purposes, which detracted from absolute performance for the 12-month period. | |

Factors Affecting Performance [Text Block] | How Did the Fund Perform Last Year? What Affected the Fund's Performance? During the 12-month period ended June 30, 2024, all share classes of the Fund underperformed the benchmark before sales charges. Both security selection and sector allocation detracted from performance, relative to the benchmark. Overall security selection detracted the most, particularly selection within consumer discretionary and health care, while selection within communication services and materials contributed. Sector allocation also detracted as losses from underweights to consumer discretionary and health care offset gains from overweights to communication services and materials. Country positioning (a result of bottom-up security analysis combined with fundamental research) was negative; losses from an overweight to China were partially offset by contributions from an overweight to Denmark. The Fund did not utilize derivatives during the six- or 12-month periods. | |
