Strategy. The Fund seeks to track the investment results, before the fees and expenses of the Fund, of the MSCI Emerging Markets Index (the Underlying Index), which is designed to measure equity market performance in the global emerging markets.

As of February 28, 2022, China represented approximately 32% of the Underlying Index by weight. The Underlying Index may include large- or mid-capitalization companies. With approximately 1,420 constituents as of February 28, 2022, the Underlying Index covers approximately 85% of the free float-adjusted market capitalization in each country. The components of the Underlying Index, and the degree to which these components represent certain industries, are likely to change over time. The Subadviser uses a passive or indexing approach to try to achieve the Funds investment objective. Unlike many investment companies, the Fund does not try to beat the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued. Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the risks of active management, such as poor security selection. Indexing seeks to achieve lower costs by keeping portfolio turnover low in comparison to actively managed investment companies. The Subadviser generally uses a representative sampling indexing strategy to manage the Fund. Representative sampling is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to that of the Underlying Index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the Underlying Index. The Fund generally invests at least 90% of its net assets in the securities of its Underlying Index and in depositary receipts representing securities in its Underlying Index. The Fund may invest the remainder of its assets in other securities, including securities not in the Underlying Index, but which the Subadviser believes will help the Fund track the Underlying Index, and in other investments, including futures contracts, options on futures contracts, other types of options and swaps related to its Underlying Index, as well as cash and cash equivalents. The Underlying Index is calculated by MSCI Inc. (the Index Provider or MSCI), which is independent of the Fund, the Manager and the Subadviser. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index. Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated.
