| Factors Affecting Performance [Text Block] | HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE? For the twelve months ended December 31, 2024, Class A shares of BrandywineGLOBAL - High Yield Fund returned 9.45%. The Fund compares its performance to the ICE BofA U.S. High Yield Index, which returned 8.20% for the same period. PERFORMANCE HIGHLIGHTS Top contributors to performance: ↑ Selection in financial services, focused on non-bank issuers, with an overweight allocation relative to the index. ↑ Selection in energy and consumer goods, driven by active involvement with management around corporate restructuring and consolidation. ↑ Avoided large structures in the media sector that had been laggards. Top detractors from performance: ↓ Underweight exposure to CCC-rated bonds & below credit rating, particularly in telecom, which benefited from interest rate cuts, expectations of a soft landing, and high carry. ↓ Duration positioning during a period of elevated interest rate volatility, where yields moved significantly up and down. ↓ Underweight exposure to health care. | |
