Strategy. Under normal circumstances, the Portfolio intends to invest at least 80% of its net assets, plus borrowings for investment purposes, in equity securities of companies located in emerging market countries or other investments that are tied economically to emerging market countries. Such equity securities may include common stocks, preferred stocks, depositary receipts, rights and warrants. For this Portfolio, an emerging market country is any country that the International Bank for Reconstruction and Development (commonly known as The World Bank) or similar major financial institution has determined to have a low or middle economy, or countries included in the MSCI Emerging Markets Index (MSCI EM Index).

Such equity securities may include common stocks, preferred stocks, depositary receipts, rights and warrants. For this Portfolio, an emerging market country is any country that the International Bank for Reconstruction and Development (commonly known as The World Bank) or similar major financial institution has determined to have a low or middle economy, or countries included in the MSCI Emerging Markets Index (MSCI EM Index). In addition, for this Portfolio, an emerging market country security is defined as a security of an issuer having one or more of the following characteristics: (i) its principal securities trading market is an emerging market country; (ii) alone, or on a consolidated basis, at least 50% of its revenues are derived from goods produced, sales made or services performed in an emerging market country; or (iii) it is organized under the laws of, or has a principal office in, an emerging market country. The Portfolios assets normally are allocated among two investment managers, each of which manages its portion of the Portfolio using a different but complementary investment strategy. One portion of the Portfolio is actively managed (Active Allocated Portion) , and one portion of the Portfolio seeks to track the performance of a particular index (Index Allocated Portion). Under normal circumstances, the Active Allocated Portion consists of approximately 25-35% of the Portfolios net assets and the Index Allocated Portion consists of approximately 65-75% of the Portfolios net assets. These percentages are targets established by the Adviser; actual allocations may deviate from these targets. In choosing investments for the Active Allocated Portion, the Sub-Adviser utilizes a proprietary screening process called Return Pattern Recognition to identify securities that it believes are likely to outperform based on specific financial and market characteristics. Such characteristics include, but are not limited to, valuation measures, market trends, operating trends, growth measures and profitability measures. Once a company is identified during the screening process, the Sub-Adviser employs a fundamental analysis of factors such as the issuers management, financial condition and industry position to select investments. The Sub-Adviser seeks to allocate investments across different emerging market countries, sectors and industries. The Active Allocated Portion may invest in companies of any size. The Sub-Adviser may sell a security for a variety of reasons, such as the issuers prospects deteriorate, marginal contributions to risk of an individual security cause the overall risk profile of the Active Allocated Portion to exceed the Sub-Advisers minimal acceptable threshold, or to make other investments believed by the Sub-Adviser to offer superior investment opportunities. The Index Allocated Portion employs a stratified sampling approach to build a portfolio whose broad characteristics match those of the MSCI EM Index. This strategy is commonly referred to as an indexing strategy. Individual securities holdings may differ from those of the MSCI EM Index, and the Portfolio may not track the performance of MSCI EM Index perfectly due to expenses and transaction costs, the size and frequency of cash flow into and out of the Portfolio, and differences between how and when the Portfolio and the MSCI EM Index are valued. The Index Allocated Portion also may invest in other instruments, such as futures and options contracts, that provide comparable exposure as the index without buying the underlying securities comprising the index. The Portfolio may also use derivatives, such as foreign currency forward contracts, futures contracts, exchange-traded futures, options contracts on securities indices, and forwards to manage equity exposure, for hedging purposes to protect against losses or reduce volatility resulting from changes in interest rates, market indices or foreign exchange rates and to reduce the Portfolios exposure to changes in the value of foreign currencies relative to the U.S. dollar. The Portfolios investments in derivatives may be deemed to involve the use of leverage because the Portfolio is not required to invest the full market value of the contract upon entering into the contract but participates in gains and losses on the full contract price. The use of derivatives also may be deemed to involve the use of leverage because the heightened price sensitivity of some derivatives to market changes may magnify the Portfolios gain or loss. The Portfolios investments in derivatives may require it to maintain a percentage of its assets in cash and cash equivalent instruments to serve as margin or collateral for the Portfolios obligations under derivative transactions.
