| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what affected its performance? Key contributors to (↑) and detractors from (↓) absolute performance: ↑ A long exposure to Surinamese sovereign credit contributed to performance following a debt restructuring that significantly reduced debt service obligations ↑ A long exposure to Egyptian local bonds contributed to returns during a period marked by positive reforms, International Monetary Fund (IMF) support, and regional support amid the Israel-Hamas conflict ↑ A long exposure to Uzbekistani local bonds, which benefited from perceptions of strengthening political institutions, contributed to returns during the period ↓ In contrast, a short exposure to South African sovereign credit detracted from returns as national elections resulted in a new coalition government expected to focus on structural reforms that may increase economic growth in South Africa ↓ Optimism about South Africa’s new government caused the South African rand to strengthen, and a short position in the currency detracted from performance ↓ Derivatives — led by credit-default swaps used to manage credit exposures and foreign exchange forwards used to manage currency exposures — hurt returns |
