The Portfolio's investment objective is to maximize total returns from price appreciation and income. The fund seeks to generate returns in excess of the benchmark through a combination of country selection, currency allocation, sector analysis and security selection. The Portfolio’s investments in sovereign debt obligations and non-U.S. corporate fixed-income securities emphasize countries that are included in the J.P. Morgan Emerging Markets Bond Index Global or are considered at the time of purchase to be emerging markets or developing countries. The Portfolio invests at least two-thirds of its total assets in sovereign and quasi-sovereign (i.e. debt issued by supranational organizations and other government-related entities) debt obligations. The Portfolio is non-diversified, meaning it may invest more of its assets in a fewer number of issuers.
