| Factors Affecting Performance [Text Block] | HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE? For the twelve months ended October 31, 2024, Class A shares of ClearBridge International Value Fund returned 17.47%. The Fund compares its performance to the MSCI All Country World ex-U.S. Index-NR and the MSCI EAFE Index-NR, which returned 24.33% and 22.97% for the same period. PERFORMANCE HIGHLIGHTS Top contributors to performance: ↑ Industria de Diseno Textil, online retailer and distributor headquartered in Spain within the consumer discretionary sector, reported its highest profitability in years, in addition operating margins increased substantially during a period where costs have been rising. Following a strong first half, sales continued to grow compared with the same period a year prior, boosted by interest in the company’s collections for the fall-winter season. ↑ Hitachi, a Japanese industrial electronics conglomerate within the industrials sector, continued to benefit from the demand and buildout of data centers and upgrading of global electrical grids. After of a decade of meaningful restructuring, Hitachi has now become a model for value creation in Japan, which in turn has motivated its management team to find further avenues for growth and returns. ↑ SAP, a German developer of enterprise software within the information technology sector, contributed as customers continued to embrace their cloud solutions, the announcement of incorporating AI into its applications, both boosted by an upgraded software release cycle, resulted in healthy revenue and earnings growth as well as increased backlogs. Top detractors from performance: ↓ Galaxy Entertainment Group, a hotel operator, gaming and resort facilities in Macauin within the consumer discretionary sector, had its share price come under pressure due to lower discretionary spending from the Chinese consumer amid economic headwinds and a real estate crisis in the country (not held at period-end). ↓ Bayer, a German pharmaceutical and agriculture company within the health care sector, saw its share price decline after seeing disappointing results from one of its most anticipated anticoagulant pipeline drugs, as well as a legal challenges in its crop business leading to increased liability estimates. ↓ Samsung Electronics, a Korean consumer electronics company within the IT sector, shares faced headwinds early in the period due to significant oversupply in its mainstay semiconductor segment. | |
