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 | Security selection contributed meaningfully to Fund performance relative to the benchmark across most sectors. Stock selection within the communication services, industrials and consumer discretionary sectors generated the largest positive contributions.

Allocations | From a sector allocation perspective, the Fund benefited from underweight positions in the consumer staples and utilities sectors.

Individual holdings | Overweight positions in Bandwidth, Revolution Medicines, and Planet Labs PBC were among the largest contributors to relative performance. These investments benefited from strong company-specific fundamentals and favorable market reception during the period.

Top Performance Detractors

Stock selection | Security selection detracted from Fund performance relative to the benchmark in only two sectors - consumer staples and health care.

Allocations | Overweight exposures to the consumer discretionary, industrials and financials sectors detracted from relative performance.

Individual holdings | Overweight positions in Vital Farms and Phreesia were the most significant individual detractors from the Fund’s relative 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 health care and consumer staples sectors contributed to the Fund’s relative performance during the period.

Individual holdings | Positions in Taiwan Semiconductor Manufacturing, a global leader in advanced semiconductor foundry manufacturing; Roche Holding, a Swiss pharmaceutical and diagnostics company; Japan Tobacco, a global tobacco and consumer products company; Mitsubishi Electric, a diversified electrical equipment and industrial systems manufacturer; and Woolworths Group, an Australian food and consumer staples retailer, were top contributors during the period.

Top Performance Detractors

Stock selection | Selections in the financials and information technology sectors hurt the Fund’s relative performance during the period.

Allocations | An underweight allocation to the financials sector, as well as overweights to the consumer staples and communication services sectors, detracted from the Fund’s relative performance during the period.

Individual holdings | Positions in SAP, a German enterprise software provider; Brambles, an Australian supply chain logistics and pallet pooling company; Nemetschek, a German design and construction software provider; Wolters Kluwer, a Dutch professional information and software services company; and Bank Rakyat Indonesia, an Indonesian commercial bank, were top detractors during the period.

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

Yield carry | The Fund’s higher than benchmark yield was a significant contributor to the Fund’s benchmark-relative performance during the period.

Sector allocation | Sector allocation was a major contributor to the Fund’s relative performance. Overweights to industrial development revenue bonds (IDR), housing and airports added to relative performance.

Credit quality allocation | While quality allocation was neutral, an overweight to not-rated bonds added to relative performance.

Credit quality security selection | While overall security selection was neutral, selection in AA-rated bonds contributed to the Fund’s performance relative to its benchmark.

Sector security selection | While overall sector security selection detracted from benchmark-relative performance, selection in prepay gas bonds was a positive contributor to Fund performance.

Top Performance Detractors

Sector security selection | Security selection detracted from benchmark-relative performance, with selection in IDR and state general obligation (GO) bonds acting as a headwind to performance relative to the benchmark.

Sector allocation | An overweight to cash detracted from relative performance.

Credit quality allocation | While quality allocation was neutral, an overweight to AAA-rated bonds detracted from relative performance.

Credit quality security selection | While overall security selection was neutral, selection in AAA-rated and A-rated bonds detracted from the Fund’s relative performance.

Performance Past Does Not Indicate Future [Text]
