Management's Discussion of Fund Performance 

The performance of Class A shares for the period presented is shown in the Average Annual Total Returns table.

Top Performance Contributors

Stock selection | Selections in the financials, consumer discretionary and materials sectors boosted the Fund’s relative performance during the annual period.

 

Allocations | Smaller allocations to the health care, consumer staples and real estate sectors buoyed Fund relative performance during the annual period.

 

Individual holdings | Positions in Northern Star Resources, an Australian gold miner; Cameco, a Canadian uranium miner; Youngone, a Korean outerwear company; and Paladin Energy, an Australian uranium miner, were top contributors to the Fund’s relative performance during the period. Not owning UnitedHealth Group, an American health insurer, also added to the Fund’s relative performance during the period.

Top Performance Detractors

Stock selection | Selections in the industrials, information technology and utilities sectors hurt the Fund’s relative performance during the annual period.

 

Allocations | A larger weighting in the consumer discretionary sector and smaller weightings in the materials and industrials sectors detracted from relative Fund performance during the annual period.

 

Individual holdings | Fund underweights in Micron Technology, an American semiconductor company, and Oracle, an American technology company, were top detractors from the Fund’s relative performance during the period. An overweight in Boston Scientific, an American medical technology company, as well as positions in Mastercard, an American payments company and Primo Brands, an American-Canadian beverage company, also detracted from the Fund’s relative performance during the period.
Performance Past Does Not Indicate Future [Text] The Fund's past performance is not a good predictor of the Fund's future performance.

Management's Discussion of Fund Performance 

The performance of Class R shares for the period presented is shown in the Average Annual Total Returns table.

Top Performance Contributors

Stock selection | Selections in the financials, consumer discretionary and materials sectors boosted the Fund’s relative performance during the annual period.

 

Allocations | Smaller allocations to the health care, consumer staples and real estate sectors buoyed Fund relative performance during the annual period.

 

Individual holdings | Positions in Northern Star Resources, an Australian gold miner; Cameco, a Canadian uranium miner; Youngone, a Korean outerwear company; and Paladin Energy, an Australian uranium miner, were top contributors to the Fund’s relative performance during the period. Not owning UnitedHealth Group, an American health insurer, also added to the Fund’s relative performance during the period.

Top Performance Detractors

Stock selection | Selections in the industrials, information technology and utilities sectors hurt the Fund’s relative performance during the annual period.

 

Allocations | A larger weighting in the consumer discretionary sector and smaller weightings in the materials and industrials sectors detracted from relative Fund performance during the annual period.

 

Individual holdings | Fund underweights in Micron Technology, an American semiconductor company, and Oracle, an American technology company, were top detractors from the Fund’s relative performance during the period. An overweight in Boston Scientific, an American medical technology company, as well as positions in Mastercard, an American payments company and Primo Brands, an American-Canadian beverage company, also detracted from the Fund’s relative performance during the period.
Performance Past Does Not Indicate Future [Text] The Fund's past performance is not a good predictor of the Fund's future performance.

Management's Discussion of Fund Performance 

The performance of Class S shares for the period presented is shown in the Average Annual Total Returns table.

Top Performance Contributors

Stock selection | Selections in the financials, consumer discretionary and materials sectors boosted the Fund’s relative performance during the annual period.

 

Allocations | Smaller allocations to the health care, consumer staples and real estate sectors buoyed Fund relative performance during the annual period.

 

Individual holdings | Positions in Northern Star Resources, an Australian gold miner; Cameco, a Canadian uranium miner; Youngone, a Korean outerwear company; and Paladin Energy, an Australian uranium miner, were top contributors to the Fund’s relative performance during the period. Not owning UnitedHealth Group, an American health insurer, also added to the Fund’s relative performance during the period.

Top Performance Detractors

Stock selection | Selections in the industrials, information technology and utilities sectors hurt the Fund’s relative performance during the annual period.

 

Allocations | A larger weighting in the consumer discretionary sector and smaller weightings in the materials and industrials sectors detracted from relative Fund performance during the annual period.

 

Individual holdings | Fund underweights in Micron Technology, an American semiconductor company, and Oracle, an American technology company, were top detractors from the Fund’s relative performance during the period. An overweight in Boston Scientific, an American medical technology company, as well as positions in Mastercard, an American payments company and Primo Brands, an American-Canadian beverage company, also detracted from the Fund’s relative performance during the period.
Performance Past Does Not Indicate Future [Text] The Fund's past performance is not a good predictor of the Fund's future performance.

Management's Discussion of Fund Performance 

The performance of Institutional 3 Class shares for the period presented is shown in the Average Annual Total Returns table.

Top Performance Contributors

Stock selection | Selections in the financials, consumer discretionary and materials sectors boosted the Fund’s relative performance during the annual period.

 

Allocations | Smaller allocations to the health care, consumer staples and real estate sectors buoyed Fund relative performance during the annual period.

 

Individual holdings | Positions in Northern Star Resources, an Australian gold miner; Cameco, a Canadian uranium miner; Youngone, a Korean outerwear company; and Paladin Energy, an Australian uranium miner, were top contributors to the Fund’s relative performance during the period. Not owning UnitedHealth Group, an American health insurer, also added to the Fund’s relative performance during the period.

Top Performance Detractors

Stock selection | Selections in the industrials, information technology and utilities sectors hurt the Fund’s relative performance during the annual period.

 

Allocations | A larger weighting in the consumer discretionary sector and smaller weightings in the materials and industrials sectors detracted from relative Fund performance during the annual period.

 

Individual holdings | Fund underweights in Micron Technology, an American semiconductor company, and Oracle, an American technology company, were top detractors from the Fund’s relative performance during the period. An overweight in Boston Scientific, an American medical technology company, as well as positions in Mastercard, an American payments company and Primo Brands, an American-Canadian beverage company, also detracted from the Fund’s relative performance during the period.
Performance Past Does Not Indicate Future [Text] The Fund's past performance is not a good predictor of the Fund's future performance.

Factors Affecting Performance [Text Block]

Management's Discussion of Fund Performance 

The performance of Institutional Class shares for the period presented is shown in the Average Annual Total Returns table.

Top Performance Contributors

Stock selection | Selections in the financials, consumer discretionary and materials sectors boosted the Fund’s relative performance during the annual period.

 

Allocations | Smaller allocations to the health care, consumer staples and real estate sectors buoyed Fund relative performance during the annual period.

 

Individual holdings | Positions in Northern Star Resources, an Australian gold miner; Cameco, a Canadian uranium miner; Youngone, a Korean outerwear company; and Paladin Energy, an Australian uranium miner, were top contributors to the Fund’s relative performance during the period. Not owning UnitedHealth Group, an American health insurer, also added to the Fund’s relative performance during the period.

Top Performance Detractors

Stock selection | Selections in the industrials, information technology and utilities sectors hurt the Fund’s relative performance during the annual period.

 

Allocations | A larger weighting in the consumer discretionary sector and smaller weightings in the materials and industrials sectors detracted from relative Fund performance during the annual period.

 

Individual holdings | Fund underweights in Micron Technology, an American semiconductor company, and Oracle, an American technology company, were top detractors from the Fund’s relative performance during the period. An overweight in Boston Scientific, an American medical technology company, as well as positions in Mastercard, an American payments company and Primo Brands, an American-Canadian beverage company, also detracted from the Fund’s relative performance during the period.
Performance Past Does Not Indicate Future [Text] The Fund's past performance is not a good predictor of the Fund's future performance.

Factors Affecting Performance [Text Block]

Management's Discussion of Fund Performance 

The performance of Class A shares for the period presented is shown in the Average Annual Total Returns table.

Top Performance Contributors

Stock selection | Selections in the materials, energy and financials sectors boosted the Fund’s relative performance during the annual period.

 

Allocations | A smaller allocation to the communication services sector and larger allocations to the energy and information technology sectors buoyed the Fund’s relative performance during the annual period.

 

Individual holdings | Positions in Samsung Electronics, a Korean technology company; Energy Fuels, an American rare earths and uranium company; Impala Platinum, a South African platinum miner; and an overweight in Northern Star Resources, an Australian gold miner, contributed to the Fund’s relative performance during the annual period. Not owning SAP, a German software company, was also a top contributor to the Fund’s relative performance during the annual period.

Top Performance Detractors

Stock selection | Selections in the consumer staples, real estate and communication services sectors hurt the Fund’s relative performance most during the annual period.

 

Allocations | Smaller weightings in the industrials and utilities sectors and a larger weighting in the consumer discretionary sector detracted from the Fund’s relative performance during the annual period.

 

Individual holdings | Positions in Flutter Entertainment, an Irish-American gambling company; Primo Brands, a Canadian-American beverage company; and Burford Capital, a litigation finance company, were top detractors from the Fund’s relative performance during the annual period. An overweight in Check Point Software Technologies, an Israeli cybersecurity company, and a zero weight in ASML, a Dutch semiconductor company, were also top detractors from the Fund’s relative performance during the annual period.

Management's Discussion of Fund Performance 

The performance of Institutional Class shares for the period presented is shown in the Average Annual Total Returns table.

Top Performance Contributors

Stock selection | Selections in the materials, energy and financials sectors boosted the Fund’s relative performance during the annual period.

 

Allocations | A smaller allocation to the communication services sector and larger allocations to the energy and information technology sectors buoyed the Fund’s relative performance during the annual period.

 

Individual holdings | Positions in Samsung Electronics, a Korean technology company; Energy Fuels, an American rare earths and uranium company; Impala Platinum, a South African platinum miner; and an overweight in Northern Star Resources, an Australian gold miner, contributed to the Fund’s relative performance during the annual period. Not owning SAP, a German software company, was also a top contributor to the Fund’s relative performance during the annual period.

Top Performance Detractors

Stock selection | Selections in the consumer staples, real estate and communication services sectors hurt the Fund’s relative performance most during the annual period.

 

Allocations | Smaller weightings in the industrials and utilities sectors and a larger weighting in the consumer discretionary sector detracted from the Fund’s relative performance during the annual period.

 

Individual holdings | Positions in Flutter Entertainment, an Irish-American gambling company; Primo Brands, a Canadian-American beverage company; and Burford Capital, a litigation finance company, were top detractors from the Fund’s relative performance during the annual period. An overweight in Check Point Software Technologies, an Israeli cybersecurity company, and a zero weight in ASML, a Dutch semiconductor company, were also top detractors from the Fund’s relative performance during the annual period.
