| Factors Affecting Performance [Text Block] | HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE? For the twelve months ended May 31, 2024, Class A shares of Western Asset Total Return Unconstrained Fund returned 5.03%. The Fund compares its performance to the Bloomberg U.S. Aggregate Index and the ICE BofA 3-Month U.S. Treasury Bill Index, which returned 1.31% and 5.45%, respectively, for the same period. PERFORMANCE HIGHLIGHTS Top contributors to performance: ↑ Yield-curve positioning, as the Fund was short the belly of the curve for the majority of the period (through the first quarter of 2024) and 10-year yields rose more than shorter- and longer-dated yields where the Fund had long duration exposure ↑ Allocation to emerging market (EM) debt, driven by the Fund’s local currency sovereign exposure ↑ Investment-grade (IG) credit exposure as spreads tightened Top detractors from performance: ↓ Duration exposure, as U.S. Treasury (UST) yields rose over the reporting period ↓ Developed market government exposure, driven by a short Japanese versus long U.S. rates position, as well as a strengthening U.S. dollar (USD) ↓ EM currency exposure, as the USD strengthened versus most currencies Use of derivatives and the impact on performance: The Fund used interest rate futures, options and swaps to manage duration and yield curve exposure, which provided a positive impact on performance. Credit default swaps (CDS) on IG and high-yield indices, as well as options on CDS, were used to manage credit exposures and had a negative impact on performance, while currency derivatives used to manage currency exposure had a slightly negative impact on performance. | |
