HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE?
For the twelve months ended December 31, 2025, Class A shares of BrandywineGLOBAL - Global Opportunities Bond Fund returned 13.17%. The Fund compares its performance to the  FTSE World Government Bond Index, which returned 7.55% for the same period.
PERFORMANCE HIGHLIGHTS
Top contributors to performance:
↑
The euro was the largest contributor to performance, supported by improving European growth expectations and sentiment. Strong relative demand amid a weakening U.S. dollar drove gains in the first half of 2025, reinforced by continued euro area disinflation that reduced macro uncertainty and supported European risk assets and the currency.
↑
Local-currency Mexican bonds also contributed to performance, supported by elevated real yields and strong investor demand for higher-yielding assets during periods of contained volatility and improved risk appetite. Banxico delivered multiple rate cuts in 2025 as inflation moderated, allowing policy to become incrementally less restrictive.
↑
U.S. Treasury duration was additive, as the Fund tactically increased exposure when yields approached 5% and growth momentum and policy expectations began to shift. Signs of a softening labor market pushed yields lower as investors priced in additional rate cuts, helping offset the fiscal and tariff-related uncertainties that weighed on markets in the first half of the year.
Top detractors from performance:
↓
The Japanese yen was the largest detractor, weighed down by persistent yield differentials and its continued role as a funding currency for global carry trades during risk-on periods. Although the Bank of Japan raised its policy rate to the highest level in 30 years, cautious guidance on the future pace of hikes limited support for the currency.
↓
The South Korean won was a moderate detractor, reflecting a challenging mix of domestic political uncertainty, sensitivity to global trade conditions, and an unfavorable relative-rate backdrop at key points during the year. Political developments in particular weighed on sentiment.
Use of derivatives and the impact on performance:
The Fund utilized currency forwards for hedging and alpha purposes, which contributed to performance. Bond futures were used as a duration management, hedging, and alpha source, which detracted from period.

PERFORMANCE HIGHLIGHTS
Top contributors to performance:
↑
The euro was the largest contributor to performance, supported by improving European growth expectations and sentiment. Strong relative demand amid a weakening U.S. dollar drove gains in the first half of 2025, reinforced by continued euro area disinflation that reduced macro uncertainty and supported European risk assets and the currency.

Local-currency Mexican bonds also contributed to performance, supported by elevated real yields and strong investor demand for higher-yielding assets during periods of contained volatility and improved risk appetite. Banxico delivered multiple rate cuts in 2025 as inflation moderated, allowing policy to become incrementally less restrictive.
↑
U.S. Treasury duration was additive, as the Fund tactically increased exposure when yields approached 5% and growth momentum and policy expectations began to shift. Signs of a softening labor market pushed yields lower as investors priced in additional rate cuts, helping offset the fiscal and tariff-related uncertainties that weighed on markets in the first half of the year.
Top detractors from performance:
↓
The Japanese yen was the largest detractor, weighed down by persistent yield differentials and its continued role as a funding currency for global carry trades during risk-on periods. Although the Bank of Japan raised its policy rate to the highest level in 30 years, cautious guidance on the future pace of hikes limited support for the currency.
↓
The South Korean won was a moderate detractor, reflecting a challenging mix of domestic political uncertainty, sensitivity to global trade conditions, and an unfavorable relative-rate backdrop at key points during the year. Political developments in particular weighed on sentiment.
Use of derivatives and the impact on performance:
The Fund utilized currency forwards for hedging and alpha purposes, which contributed to performance. Bond futures were used as a duration management, hedging, and alpha source, which detracted from period.

PERFORMANCE HIGHLIGHTS
Top contributors to performance:
↑
The euro was the largest contributor to performance, supported by improving European growth expectations and sentiment. Strong relative demand amid a weakening U.S. dollar drove gains in the first half of 2025, reinforced by continued euro area disinflation that reduced macro uncertainty and supported European risk assets and the currency.
↑
Local-currency Mexican bonds also contributed to performance, supported by elevated real yields and strong investor demand for higher-yielding assets during periods of contained volatility and improved risk appetite. Banxico delivered multiple rate cuts in 2025 as inflation moderated, allowing policy to become incrementally less restrictive.
↑
U.S. Treasury duration was additive, as the Fund tactically increased exposure when yields approached 5% and growth momentum and policy expectations began to shift. Signs of a softening labor market pushed yields lower as investors priced in additional rate cuts, helping offset the fiscal and tariff-related uncertainties that weighed on markets in the first half of the year.
Top detractors from performance:
↓
The Japanese yen was the largest detractor, weighed down by persistent yield differentials and its continued role as a funding currency for global carry trades during risk-on periods. Although the Bank of Japan raised its policy rate to the highest level in 30 years, cautious guidance on the future pace of hikes limited support for the currency.
↓
The South Korean won was a moderate detractor, reflecting a challenging mix of domestic political uncertainty, sensitivity to global trade conditions, and an unfavorable relative-rate backdrop at key points during the year. Political developments in particular weighed on sentiment.
Use of derivatives and the impact on performance:
The Fund utilized currency forwards for hedging and alpha purposes, which contributed to performance. Bond futures were used as a duration management, hedging, and alpha source, which detracted from period.
