Strategy. The Fund pursues its investment objective by investing, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in securities of companies that portfolio management believes will benefit significantly from advances or improvements in technology. These companies generally fall into two categories: companies that portfolio management believes have or will develop products, processes, or services that will provide significant technological advancements or improvements; and companies that portfolio management believes rely extensively on technology in connection with their operations or services. Some of the industries and companies likely to be represented in the Funds portfolio include e-commerce (companies doing business through the Internet); computer (hardware and software); communications (voice, data, and wireless); industrials; Internet (software, … Show more… The Fund pursues its investment objective by investing, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in securities of companies that portfolio management believes will benefit significantly from advances or improvements in technology. These companies generally fall into two categories: companies that portfolio management believes have or will develop products, processes, or services that will provide significant technological advancements or improvements; and companies that portfolio management believes rely extensively on technology in connection with their operations or services. Some of the industries and companies likely to be represented in the Funds portfolio include e-commerce (companies doing business through the Internet); computer (hardware and software); communications (voice, data, and wireless); industrials; Internet (software, services, and infrastructure equipment); and media and entertainment. The Fund implements this policy by investing primarily in equity securities of U.S. and foreign companies selected for their growth potential. The Fund typically invests at least 40% of its net assets in securities of issuers or companies that are economically tied to different countries throughout the world, excluding the United States. An issuer is deemed to be economically tied to a country or countries outside of the United States if one or more of the following tests are met: (i) the issuer is organized in, or its primary business office or principal trading market of its equity is located in, a country outside of the United States; (ii) a majority of the issuers revenues are derived from outside of the United States; or (iii) a majority of the issuers assets are located outside of the United States. The Fund may have exposure to emerging markets. From time to time, the Fund may invest in shares of companies through initial public offerings. The Fund has a fundamental policy to invest 25% or more of the value of its total assets in the industries within the information technology sector in the aggregate. The Fund is classified as nondiversified, which allows it to hold larger positions in more securities as compared to a fund that is classified as diversified. Portfolio management applies a bottom-up approach in choosing investments. In other words, portfolio management looks at companies one at a time to determine if a company is an attractive investment opportunity and if it is consistent with the Funds investment policies. Factors that portfolio management may consider in its fundamental analysis include the strength of a companys balance sheet and a companys projected returns or growth rates. Portfolio management will generally consider selling a position when, among other things, the investment thesis for owning a position has changed or if the position exceeds its targeted value. As part of its investment process, portfolio management considers environmental, social, and governance (ESG) risks and opportunities (ESG Factors) that it believes are financially material, alongside other fundamental investment factors. Examples of potential financially material ESG Factors include: corporate governance, company culture, exposure to climate change, and human capital management. To assess ESG Factors, portfolio management uses issuer reports, third-party data, and internally-generated analyses and may engage directly with issuers. ESG Factors are one of many considerations in the investment decision-making process, may not be determinative in deciding to include or exclude an investment from the portfolio, and may not be considered for every investment decision. The Fund may seek to earn additional income through lending its securities to certain qualified broker-dealers and institutions, in an amount equal to up to one-third of its total assets as determined at the time of the loan origination.
