Investment Objective

The Fund seeks long-term growth of capital.

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.

Annual Fund Operating Expenses

(expenses that you pay each year as a percentage of the value of your investment)

Management Fee	0.64	%
Distribution and Service (12b-1) Fees	0.25	%
Other Expenses	0.16	%
Acquired Fund Fees and Expenses¹	0.03	%
Total Annual Fund Operating Expenses	1.08	%
Fee Waiver and/or Expense Reimbursement²	-0.08	%
Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement	1.00	%

¹ "Acquired Fund Fees and Expenses" are indirect fees and expenses that the Fund incurs from investing in the shares in the shares of other investment companies. Please note that the amount of Total Annual Fund Operating Expenses shown in the above table may differ from the ratio of expenses to average net assets included in the "Financial Highlights" section of this Prospectus, which reflects the operating expenses of the Fund and does not include indirect expenses such as Acquired Fund Fees and Expenses.

²Park Avenue Institutional Advisers LLC, the Fund's investment manager (the "Manager"), has contractually agreed through April 30, 2026 to waive certain fees and/or reimburse certain expenses incurred by the Fund to the extent necessary to limit the Fund's Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement to 0.97% of the Fund's average daily net assets (excluding, if applicable, any acquired fund fees and expenses, taxes, interest, transaction costs and brokerage commissions, litigation and extraordinary expenses). The limitation may not be increased or terminated prior to this time without action by the Board of Trustees.

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:

				1 Year				3 Years				5 Years				10 Years
Guardian Growth & Income VIP Fund				$	102			$	336			$	588			$	1,310

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. For the most recent fiscal year, the Fund's portfolio turnover rate was 45% of the average value of its portfolio.

Principal Investment Strategies

The Fund invests primarily in the equity securities of U.S. companies that AllianceBernstein L.P., the Fund's subadviser (the "Subadviser"), believes are undervalued, focusing on dividend-paying securities. Although the Fund invests primarily in large capitalization companies, the Fund may invest in companies with different market capitalizations (i.e., mid capitalization). The Subadviser defines large capitalization companies as companies with market capitalizations similar to companies in the Russell 1000® Value Index (the "Index") at the time of purchase. Although expected to change frequently, the market capitalization range of the Index was approximately $272 million to $710 billion as of March 31, 2025. The Fund may also invest in foreign securities.

The Subadviser believes that, over time, a company's stock price will come to reflect its intrinsic economic value. The Subadviser depends heavily upon the fundamental analysis and research of its internal research staff in making investment decisions for the Fund. The research staff follows a primary research universe of approximately 500 primarily U.S. companies. In determining a company's intrinsic economic value, the Subadviser takes into account many fundamental and financial factors that it believes bear on the company's ability to perform in the future, including earnings growth, prospective cash flows, dividend growth and growth in book value. The Subadviser then ranks each of the companies in its research universe in the relative order of disparity between their intrinsic economic values and their current stock prices, with companies with the greatest disparities receiving the highest rankings (i.e., being considered the most undervalued). The Subadviser anticipates that the Fund's portfolio normally will include companies ranking in the top three deciles of the Subadviser's valuation model.

The Subadviser recognizes that the perception of what is a "value" stock is relative and the factors considered in determining whether a stock is a "value" stock may, and often will, have differing relative significance in different phases of an economic cycle. Also, at different times, and as a result of how individual companies are valued in the market, the Fund may be attracted to investments in companies engaged in particular types of business (e.g., banks and other financial institutions), although the Fund does not intend to concentrate in any particular industries or businesses. The Fund's emphasis upon particular industries or sectors will be a by-product of the stock selection process rather than the result of assigned targets or ranges.

The Subadviser typically may sell investments when it believes that they no longer offer attractive future returns compared with other investment opportunities or that they present undesirable risks or in an attempt to limit losses on investments that may decline or have declined in value.

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 very 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 the spread of infectious diseases, 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 and its investments. The market value of securities in which the Fund invests is based upon the market's perception of value and is not necessarily an objective measure of the securities' value. Changes to the market value of securities in which the Fund invests may be rapid and unpredictable. 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. The Fund may actively and frequently trade portfolio securities, which may lead to higher transaction costs that may negatively affect the Fund's performance. 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.

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.

Large-Capitalization Company Risk. Large-capitalization companies may be unable to attain the same growth rate of small- or mid-capitalization companies. In addition, large-capitalization companies may be unable to respond to competitive challenges or opportunities as quickly as smaller companies.

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.

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.

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.

Dividend-Paying Stock Risk. As a category, dividend-paying stocks may underperform non-dividend paying stocks (and the stock market as a whole) over any period of time. In addition, issuers of dividend-paying stocks may have discretion to defer or stop paying dividends for a stated period of time or may be unable to pay a dividend during certain periods as a result of, among other things, legal or regulatory restrictions. If the dividend-paying stocks held by the Fund reduce or stop paying dividends, the Fund's ability to generate income may be adversely affected. During certain periods, dividend-paying stocks, including those that meet the Fund's investment criteria, may not be widely available and/or may be highly concentrated in only a few market sectors.

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, tariffs, or other measures by the United States or other governments and supranational organizations. Economic sanctions may be, and have been, imposed against certain countries, organizations, companies, entities and/or individuals. Certain foreign markets may rely heavily on particular industries or foreign capital and are more vulnerable to diplomatic developments (including regional and global, military or other conflicts), the imposition of economic sanctions, changes in international trading patterns, trade barriers (including tariffs) and other protectionist or retaliatory measures. Economic sanctions and other similar governmental actions or developments could, among other things, adversely impact the value and liquidity of the Fund's foreign

investments and the Fund's ability to invest in foreign investments and thus make the Fund's investments in such securities less liquid or illiquid. 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 and may make the return on an investment increase or decrease, unrelated to the quality or performance of the investment itself. 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.
