Fees and Expenses of the Fund

This table shows the fees and expenses that you may pay if you buy, hold and sell shares of the Fund. The table does not reflect charges, fees or expenses that are, or may be, imposed under your variable annuity contract or variable life insurance policy through which Fund shares are offered as an investment option. If those charges, fees or expenses were reflected, the fees and expenses shown in the table would be higher. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the fee table or example below. For information about these charges, fees and expenses, please refer to the applicable contract or policy prospectus.

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. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. This Example does not reflect charges, fees or expenses that are, or may be, imposed under your variable annuity contract or variable life insurance policy, and would be higher if it did. The Example reflects contractual fee waivers and/or expense reimbursements only for the duration of the current commitment, if applicable. 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. These costs, which are not reflected in the Annual Fund Operating Expenses or in the Example, affect the Fund's performance. As of the end of its most recent fiscal year (for the period from October 25, 2021 through December 31, 2021), the Fund's portfolio turnover rate was 93% of the average value of its portfolio.

Principal Investment Strategies

FIAM LLC, the Fund's subadviser (the "Subadviser"), seeks to achieve the Fund's objective by investing, under normal circumstances, at least 80% of its net assets plus any borrowings for investment purposes (measured at the time of investment) in stocks, or other investments that the Subadviser believes have similar economic characteristics, of mid-capitalization companies. The Subadviser defines mid-capitalization companies as companies with market capitalizations similar to companies in the Russell Midcap® Index (the "Russell Index") or the S&P MidCap 400® Index (the

"S&P 400 Index") at the time of purchase. Although expected to change frequently, the market capitalization range of the Russell Index was approximately $136.3 million to $61.3 billion, and the market capitalization range of the S&P 400 Index was approximately $3.7 billion to $14.6 billion, as of March 31, 2022. The Fund may also invest in securities of companies with smaller or larger market capitalizations.

The Fund may invest in equity securities of domestic or foreign issuers. The Fund typically allocates its assets across different market sectors, including communication services, consumer discretionary, consumer staples, energy, financials, health care, industrials, information technology, materials, real estate, and utilities, using other portfolio managers of the Subadviser to handle investments within each sector. The Subadviser expects the Fund's sector allocations will approximate the sector weightings of the S&P 400 Index.

The Fund may invest in either "growth" stocks, "value" stocks, or both. The Subadviser uses fundamental analysis, which involves a "bottom-up" assessment of an issuer's potential for success in light of factors including its financial condition, earnings outlook, strategy, management, industry position, and market and economic conditions, to select the Fund's investments.

Principal Investment Risks

The risks summarized below are the principal risks of investing in the Fund. There is no guarantee that the Fund will achieve its investment objective and it is possible to lose money by investing in the Fund.

Market Risk. The financial and securities markets are volatile and may be affected by political, regulatory, social, economic, and other global market developments and disruptions, including those arising out of geopolitical events, public health emergencies (such as pandemics and epidemics), natural disasters, terrorism, and governmental or quasi-governmental actions. These events may negatively affect issuers, industries and markets worldwide and adversely affect the Fund. The price, value or liquidity of the Fund's investments may decline and will fluctuate, sometimes rapidly and unpredictably, in response to general market conditions or other factors. Different sectors of the market, issuers, and security types may react differently to such developments.

Issuer Risk. The Fund's investments may be adversely affected by a number of factors that directly relate to the issuer of securities held by the Fund, such as its earnings prospects and overall financial position. In addition, an issuer in which the Fund invests, or to which it has exposure, may perform poorly because of poor management decisions or other events, conditions, or factors, which could also negatively affect the Fund.

Active Management Risk. The Fund is actively managed by the Subadviser. There is no guarantee that the Subadviser's investment techniques, risk analysis, and judgment implemented in making investment decisions for the Fund will be accurate or will produce the desired outcome. As a result, the Fund may be adversely affected and may underperform its benchmark index or funds with similar investment objectives. The Fund may actively and frequently trade portfolio securities, which may lead to higher transaction costs that may negatively affect the Fund's performance.

Equity Securities Risk. The price or value of the Fund's investments in a company's equity securities, such as common or preferred stock, may rise or fall rapidly or unpredictably and are subject to real or perceived changes in the company's financial condition and overall market and economic conditions. Equity securities are normally more volatile than fixed-income investments. Common stocks generally represent the riskiest investment in a company and preferred stocks generally rank junior to a company's debt with respect to dividends, which the company may or may not declare.

Mid-Capitalization Company Risk. Securities of mid-capitalization companies may be more speculative, volatile and less liquid than securities of large-capitalization companies. Mid-capitalization companies tend to have limited product and market diversification and financial resources, which may negatively affect their performance. In addition, mid-capitalization companies may have less experienced management and be more vulnerable to adverse developments than larger companies.

Growth Investment Style Risk. Different investment styles tend to perform differently and shift in and out of favor depending on changes in market and economic sentiment and conditions. Securities of "growth" companies may be more volatile than other stocks and may involve special risks. If the Subadviser's perception of a company's growth potential is not realized, the securities purchased may not perform as expected and may be out of favor for an extended period of time, reducing the Fund's returns. Thus, the Fund may underperform other equity funds that employ a different investment style during such periods.

Value Investment Style Risk. Different investment styles tend to perform differently and shift in and out of favor depending on changes in market and economic sentiment and conditions. The Fund invests in stocks believed by the Subadviser to be undervalued, but that may not realize their perceived value for extended periods of time or may never

realize their perceived value. Thus, the Fund may underperform other equity funds that employ a different investment style during such periods.

Foreign Investment and Currency Risk. Foreign investments, or exposure to foreign markets, present greater risks than investing in securities of U.S. issuers. Foreign securities are particularly susceptible to liquidity and valuation risk and may be especially volatile. These investments are subject to additional risks, including: smaller markets; differing reporting, accounting, and auditing standards; nationalization, expropriation, or confiscatory taxation; foreign currency fluctuations, currency blockage, or replacement; potential for default on sovereign debt; and political changes or diplomatic developments, which may include the imposition of economic sanctions or other measures by the United States or other governments and supranational organizations. The Fund's foreign investments that are denominated in or provide exposure to a foreign currency may be negatively affected by a decline in the foreign currency's value relative to the U.S. dollar. The value of foreign currencies may fluctuate quickly and significantly. Foreign investments may also be subject to risk of loss because of more or less foreign government regulation, less public information, and less stringent investor protections and disclosure standards.

New/Small Fund Risk. The Fund has limited or no operating history and may initially operate with a small asset base. There can be no assurance that the Fund will be successful or grow to or maintain a viable size.

Sector Risk. To the extent the Fund's investments focus on one or more sectors of the economy, the Fund's performance will be particularly susceptible to conditions and developments relating to such sector(s). In addition, the Fund will be more exposed to price movements affecting companies in such sector(s) than a more broadly invested fund.
