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 and other fees to financial intermediaries, which are not reflected in the table and Example below. Additional fees and expenses will be applied at the variable contract level. Those fees and expenses are described in your variable contract prospectus. If the information below were to reflect the deduction of variable contract charges, fees and expenses would be higher.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover 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. During the most recent fiscal year, the Fund’s portfolio turnover rate was 24% of the average value of its portfolio.

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 does not reflect expenses and charges which are, or may be, imposed under your variable contract. If the examples were to reflect the deduction of such charges, the costs shown would be greater. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem or hold 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. Although your actual costs and returns might be higher or lower, based on these assumptions your costs would be:

Principal Investment Strategy

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Fund invests at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in common stocks of large capitalization companies. For purposes of this policy, large capitalization companies have market capitalizations that fall within the market capitalization range of companies in the Russell 1000^® Growth Index at the time of purchase (as of March 31, 2022, and as provided by the Sub‑Adviser, this range was between $0.4 billion and $2,849.5 billion). Because the Fund’s definition of large capitalization companies is dynamic, the lower and upper limits on market capitalization will change with the markets. The Fund will invest primarily in common stocks of well established companies the Sub‑Adviser believes have long-term growth potential. In selecting the Fund’s investments, the Sub‑Adviser seeks investments in companies that have the ability to pay increasing dividends through strong cash flow. The Sub‑Adviser’s approach looks for companies with an above-average rate of earnings growth and a lucrative niche in the

economy that gives them the ability to sustain earnings momentum even during times of slow economic growth. The Sub‑Adviser believes when a company increases its earnings faster than both inflation and the overall economy, the market will eventually reward it with a higher stock price. The Fund may at times invest significantly in technology stocks. The Fund may sell securities for a variety of reasons, such as to secure gains, limit losses, or redeploy assets into more promising opportunities. While the Fund’s sector and industry exposure is expected to vary over time, as of February 28, 2022, the Fund had significant exposure to the Communication Services Sector, Consumer Discretionary Sector, and Information Technology Sector, as each sector is defined by the Global Industry Classification Standard.

In pursuing its investment objective, the Sub‑Adviser has the discretion to purchase some securities that do not meet its normal investment criteria, as described above, when it perceives an unusual opportunity for gain. Those situations might arise when the Sub‑Adviser believes a security could increase in value for a variety of reasons, including a change in management, an extraordinary corporate event, a new product introduction or innovation, or a favorable competitive development.

While most assets will be invested in exchange-listed U.S. common stocks, other securities may also be purchased, including foreign stocks (up to 30% of total assets), convertible securities, and preferred stocks, in keeping with the Fund’s objectives.

Principal Risks of Investing

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with all mutual funds, an investor is subject to the risk that his or her investment could lose money. In addition to this risk, the Fund is subject to the principal risks described below.

Equity Securities Risk. In general, prices of equity securities are more volatile than those of fixed income securities. The prices of equity securities fluctuate, and sometimes widely fluctuate, in response to activities specific to the issuer of the security as well as factors unrelated to the fundamental condition of the issuer, including general market, economic and political conditions.

“Growth” Investing Risk. The possibility that the Fund’s investments in securities of companies perceived to be “growth” companies may underperform when the Fund’s investment style shifts out of favor and may be more volatile than other securities because they are more sensitive to investor perceptions of the issuing company’s growth of earnings potential. Also, because growth companies usually invest a high portion of earnings in their businesses, growth stocks may lack the dividends of some value stocks that can cushion stock prices in a falling market.

Market Risk. The possibility that the values of, and/or the income generated by, securities held by the Fund may decline, sometimes unpredictably, due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Large‑Cap Securities Risk. The possibility that the Fund’s investments in larger companies may underperform relative to those of smaller companies. Larger more established companies may be unable to respond quickly to new competitive challenges such as changes in technology and consumer tastes and may not be able to attain the high growth rate of successful smaller companies, especially during extended periods of economic expansion.

Sector Risk. The possibility that the Fund may invest a substantial portion of its assets within one or more economic sectors or industries, which may change from time to time. At times, the Fund may have a significant portion of its assets invested in securities of companies conducting business in a broadly related group of industries within an economic sector. Companies in the same economic sector may be similarly affected by economic or market events, making the Fund more vulnerable to unfavorable developments in that economic sector, including adverse market conditions, legislative or regulatory changes, and/or increased competition affecting that sector, than funds that invest more broadly. While the Fund’s sector and industry exposure is

expected to vary over time, as of February 28, 2022, the Fund had significant exposure to the Information Technology Sector, Consumer Discretionary Sector, and Communication Services Sector. In addition to these general risks, the sectors specified are also subject to the risks described below.

Information Technology Sector Risk. The Information Technology Sector includes companies that offer software and information technology services, manufacturers and distributors of technology hardware and equipment such as communications equipment, cellular phones, computers and peripherals, electronic equipment and related instruments and semiconductors. The prices of the securities of companies operating in the Information Technology Sector are closely tied to market competition, increased sensitivity to short product cycles and aggressive pricing, and problems with bringing products to market.

Consumer Discretionary Sector Risk. The manufacturing segment of the Consumer Discretionary Sector includes automotive, household durable goods, leisure equipment, and textiles and apparel. The services segment includes restaurants, hotels, and other leisure facilities, media production and services, and consumer retailing and services. The performance of companies operating in this sector has historically been closely tied to the performance of the overall economy, and also is affected by economic growth, consumer confidence, social trends, attitudes and spending. Changes in demographics, disposable income levels, and consumer tastes also can affect the demand for, and success of, consumer products and services in the marketplace. Moreover, the Consumer Discretionary Sector encompasses those businesses that tend to be the most sensitive to economic cycles.

Communication Services Sector Risk. Communication services companies are particularly vulnerable to the potential obsolescence of products and services due to technological advancement and the innovation of competitors. Companies in the communication services sector may also be affected by other competitive pressures, such as pricing competition, as well as research and development costs, substantial capital requirements and government regulation. Additionally, fluctuating domestic and international demand, shifting demographics and often unpredictable changes in consumer tastes can drastically affect a communication services company’s profitability. While all companies may be susceptible to network security breaches, certain companies in the communication services sector may be particular targets of hacking and potential theft of proprietary or consumer information or disruptions in service, which could have a material adverse effect on their businesses.

Foreign Investment Risk. The possibility that the Fund’s investments in foreign securities may be adversely affected by political, social, and economic conditions affecting foreign issuers or decreases in foreign currency values relative to the U.S. dollar. Investments in foreign markets may be subject to greater market volatility, decreased market liquidity, and higher transaction and custody costs. Foreign issuers also may be subject to less government and exchange regulation and there may be less reliable financial information available for such issuers and their securities.

Management Risk. The possibility that the investment decisions, techniques, analyses or models implemented by the Fund’s Sub‑Adviser in seeking to achieve the Fund’s investment objective may not produce the returns expected, may cause the Fund’s shares to lose value or may cause the Fund to underperform relevant benchmarks or other funds with similar investment objectives.

Cybersecurity Risk. The possibility that the Fund could be harmed by intentional cyberattacks and other cybersecurity breaches, including unauthorized access to the Fund’s assets, customer data and confidential shareholder 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.

An investment in the Fund may be appropriate for investors who are willing to accept the risks and uncertainties of investing in common stocks in the hope of earning above-average long-term growth of capital and income.
