Fees and Expenses

This table describes the fees and expenses that you may pay if you buy, hold, and sell shares of the fund. You may pay other fees, such as brokerage commissions or insurance contract fees and expenses, which are not reflected in the table and example below. If these additional fees and expenses were reflected, expenses shown would be higher.

Example This example is intended to help you compare the cost of investing in the fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the fund for the time periods indicated and then redeem all of your shares at the end of those periods, that your investment has a 5% return each year, and that the fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Portfolio Turnover The fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when the fund’s shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund’s performance. During the most recent fiscal year, the fund’s portfolio turnover rate was 65.4% of the average value of its portfolio.

Investments, Risks, and Performance

Principal Investment Strategies

The fund normally invests at least 80% of its net assets (plus any borrowings for investment purposes) in the common stocks of companies engaged in the research, development, production, or distribution of products or services related to health care, medicine, or the life sciences (collectively termed “health sciences”). Any derivatives that provide exposure to the investment focus suggested by the fund’s name, or to one or more market risk factors associated with the investment focus suggested by the fund’s name, are counted (as applicable) toward compliance with the fund’s 80% investment policy.

While the fund can invest in companies of any size, the majority of fund assets are expected to be invested in large- and mid-cap companies. The fund defines the health sciences industry broadly and divides it into four main areas: pharmaceutical companies; health care services companies; medical products and devices providers; and biotechnology firms. The fund’s allocation among these four areas will vary depending on the relative potential the adviser sees within each area and the outlook for the overall health sciences sector.

The fund uses fundamental, bottom-up analysis that seeks to identify high-quality companies and the most compelling investment opportunities. In general, the fund follows a growth investment strategy, seeking companies whose earnings are expected to grow faster than inflation and the economy in general. When stock valuations seem unusually high, however, the fund may follow a value approach, seeking companies that are seemingly undervalued. The fund generally seeks investments in companies that are developing new and effective medicines, as well as companies whose business models reduce costs or improve quality in health care systems.

While most assets are typically invested in U.S. common stocks, the fund may invest in foreign stocks in keeping with its objective(s). The fund’s investments may include holdings in privately held companies and companies that only recently began to trade publicly.

Principal Risks

As with any fund, there is no guarantee that the fund will achieve its objective(s). The fund’s share price fluctuates, which means you could lose money by investing in the fund. The principal risks of investing in this fund, which may be even greater in unfavorable or uncertain market conditions, are summarized as follows:

Health sciences or health care companies: A fund that focuses its investments in specific industries or sectors is more susceptible to adverse developments affecting those industries and sectors than a more broadly diversified fund. Because the fund invests significantly in health sciences or health care companies, the fund may perform poorly during a downturn in the relevant industry. Health care and health sciences companies can be adversely affected by, among other things, legislative or regulatory changes, intense competitive challenges, the need for government approval to offer products and services, increases or decreases in the cost of or demand for medical products and services, product liability claims, an increased emphasis on outpatient services, pricing pressure (including price discounting), and product obsolescence. Health care and health sciences companies are also heavily dependent on patent protections, and the expiration of a company’s patent may adversely affect that company’s profitability.

Market conditions: The value of the fund’s investments may decrease, sometimes rapidly or unexpectedly, due to factors affecting an issuer held by the fund, particular industries, or the overall securities markets. A variety of factors can increase the volatility of the fund’s holdings and markets generally, including geopolitical developments (such as trade and tariff arrangements, sanctions, and cybersecurity attacks), recessions, inflation, rapid interest rate changes, war, military conflict, acts of terrorism, natural disasters, and outbreaks of infectious illnesses or other widespread public health issues (such as the coronavirus pandemic) and related governmental and public responses. Certain events may cause instability across global markets, including reduced liquidity and disruptions in trading markets, while some events may affect certain geographic regions, countries, sectors, and industries more significantly than others. Government intervention in markets may impact interest rates, market volatility, and security pricing. These adverse developments may cause broad declines in market value due to short-term market movements or for significantly longer periods during more prolonged market downturns.

Large- and mid-cap stocks: Securities issued by large- and mid-cap companies tend to be less volatile than securities issued by small-cap companies. However, large-cap companies may not be able to attain the high growth rates of successful small-cap companies, especially during strong economic periods, and may be unable to respond as quickly to competitive challenges. The fund’s share price could fluctuate more than the share price of a fund that invests only in large-cap companies as stocks of mid-cap companies entail greater risk and are usually more volatile than stocks of large-cap companies.

Investing style: Because the fund may hold stocks with either growth or value characteristics, it could underperform other funds that take a strictly growth or value approach to investing when one style is currently in favor. Growth stocks tend to be more volatile than the overall stock market and can have sharp price declines as a result of earnings disappointments. Value stocks carry the risk that the market will not recognize their intrinsic value for a long time (or at all) or that they are actually appropriately priced at a low level.

Foreign investing: Non-U.S. securities tend to be more volatile and have lower overall liquidity and trading volume than investments in U.S. securities and may lose value because of adverse local, political, social, or economic developments overseas, or due to changes in the exchange rates between foreign currencies and the U.S. dollar. Further, securities of non-U.S. issuers are subject to trading markets with potential governmental interference, varying regulatory, auditing, and accounting standards, and settlement and clearance practices that differ from those of U.S. issuers. Investment in non-U.S. securities also carries currency risk. Any attempts to hedge currency risk could be unsuccessful. Such investments may have higher transaction costs compared with U.S. markets. Investments in emerging market countries are subject to greater risk and overall volatility than investments in developed markets.

Private placements and IPOs: Investments in the stocks of privately held companies and in companies that only recently began to publicly trade, such as initial public offerings or IPOs, involve greater risks than investments in stocks of companies that have traded publicly on an exchange for extended time periods. There is significantly less information available about these companies’ business models, quality of management, earnings growth potential, and other criteria that are normally considered when evaluating the investment prospects of a company. Private placements and other restricted securities held by the fund are typically considered to be illiquid and tend to be difficult to value since there are no market prices and less overall financial information available. The adviser evaluates a variety of factors when assigning a value to these holdings, but the determination involves some degree of subjectivity and the value assigned for the fund may differ from the value assigned by other mutual funds holding the same security.

Liquidity: A particular investment or an entire market segment may become less liquid or even illiquid, sometimes abruptly, which could limit the fund’s ability to purchase or sell holdings in a timely manner at a desired price. An inability to sell a portfolio holding can adversely affect the fund’s overall value or prevent the fund from being able to take advantage of other investment opportunities. Liquidity risk may be magnified during periods of substantial market volatility and unexpected episodes of illiquidity may limit the fund’s ability to pay redemption proceeds without selling holdings at an unfavorable time or at a suitable price. Large redemptions may also have a negative impact on the fund’s overall liquidity.

Active management: The fund’s overall investment program and holdings selected by the fund’s investment adviser may underperform the broad markets, relevant indices, or other funds with similar objectives and investment strategies.

Stock investing: Stocks generally fluctuate in value more than bonds and may decline significantly over short time periods. There is a chance that stock prices overall will decline because stock markets tend to move in cycles, with periods of rising and falling prices. The value of stocks held by the fund may decline due to general weakness or volatility in the stock markets in which the fund invests or because of factors that affect a particular company or industry.

Cybersecurity breaches: The fund could be harmed by intentional cyberattacks and other cybersecurity breaches, including unauthorized access to the fund’s assets, confidential information, or other proprietary information. In addition, a cybersecurity breach could cause one of the fund’s service providers or financial intermediaries to suffer unauthorized data access, data corruption, or loss of operational functionality.

Performance

The following performance information provides some indication of the risks of investing in the fund. The fund’s performance information represents only past performance and is not necessarily an indication of future results.

Purchase and Sale of Fund Shares

The fund is not sold directly to the general public but is instead offered as an underlying investment option for variable annuity or variable life insurance contracts. Although the fund does not require a minimum amount for initial or subsequent purchases from insurance companies, your insurance company may impose investment minimums for your purchases of the fund.

You may purchase, redeem, or exchange shares of the fund on any day the New York Stock Exchange is open for business. You must purchase, redeem, and exchange shares through your insurance company.

Tax Information

The fund distributes any dividends and capital gains to its shareholders, which are the insurance company separate accounts that sponsor your variable annuity or variable life insurance contract. Variable product owners seeking to understand the tax consequences of their investment, including redemptions of fund shares and the impact of dividend and capital gains distributions by the fund, should consult with the insurance company that issued their variable product or refer to their variable annuity or variable life insurance contract prospectus.

Payments to Insurance Companies, Broker-Dealers, and Other Financial Intermediaries

The fund is generally available only through variable annuity or variable life insurance contracts. The fund and/or its related companies may make payments to a sponsoring insurance company or other financial intermediary for the sale of fund shares and related services. These payments may create a conflict of interest by influencing the insurance company or other financial intermediary to recommend the fund over another investment option or by influencing an insurance company to include the fund as an underlying investment option in a variable contract. The prospectus (or other offering document) for your variable contract may contain additional information about these payments. Ask your insurance company or financial intermediary, or visit your insurance company’s or financial intermediary’s website, for more information.
