In general, for a period of up to 36 months from the time of any deferral, reimbursement, or payment pursuant to the above-described contractual expense limitations, the Adviser may recover from the Portfolio fees deferred and expenses paid to the extent that such repayment would not cause the Net Annual Portfolio Operating Expenses to exceed the contractual expense limitation amounts set forth above, but any repayment will not include interest. The Adviser’s recovery is limited to the lesser of the expense limitation at the time of the waiver and the time of recapture.

The example assumes that you invest $10,000 for the time periods indicated and then redeem all of your shares at the end of those periods.

Portfolio Turnover The Portfolio 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 Annual Portfolio Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s turnover rate was 21% of the average value of its portfolio. 0.21 Principal Investment Strategies The Portfolio seeks to achieve its objective mainly by acquiring common stocks of companies that the Adviser believes have a high probability of growing net asset value and a low probability of financial impairment. Adhering to this strict value discipline, the Portfolio generally will be concentrated in the Adviser’s highest conviction investment ideas (or investments that the Adviser believes to have the highest probability of above average returns) and will typically hold 20-40 positions. The Adviser seeks investments whose market prices are low in relation to what it believes is their intrinsic value and/or whose total return potential is considered to be high. The Adviser believes this both lowers investment risk and increases capital appreciation and total return potential. Accordingly, the Adviser seeks to identify investment opportunities through intensive research of individual companies and, generally, does not focus solely on stock market conditions and other macro factors. For these reasons, the Adviser may seek investments in the equity securities and senior securities, such as convertible securities, preferred stocks and debt instruments (including high-yield and distressed securities, often referred to as “junk”, that may be in default and may have any or no credit rating) of companies in industries that are believed to be undervalued or temporarily depressed. The Portfolio also invests in both domestic and foreign securities. Third Avenue follows a strategy of long-term investing. The Adviser will generally sell an investment when there has been a fundamental change in the business or capital structure of the company which significantly affects the investment’s inherent value or when it believes that the market value of an investment is overpriced relative to its intrinsic value. Temporary Defensive Positions. In anticipation of or in response to adverse market or other conditions or atypical circumstances such as unusually large cash inflows or redemptions, the Portfolio may temporarily hold a larger than normal portion of its assets in U.S. Government securities, money market funds, cash, exchange-traded funds, cash equivalents, or short-term investments. The Adviser will determine when market conditions warrant temporary defensive measures with respect to the Portfolio. Under such conditions, the Portfolio may not invest in accordance with its investment objective or principal investment strategies and may not achieve its investment objective. Market Risk. Prices of securities (and stocks in particular) have historically fluctuated. The value of the Portfolio will similarly fluctuate and you could lose money. Markets may additionally be impacted by negative external and/or direct and indirect economic factors such as pandemics, natural disasters, global trade policies and political unrest or uncertainties. The adverse impact of any one or more of these events on market value of fund investments could be significant and cause losses. <div style="display: none"></div> The value of the Portfolio will similarly fluctuate and you could lose money. Style Risk. Value securities involve the risk that they may never reach their expected full market value, either because the market fails to recognize the securities’ intrinsic value or the expected value was misgauged. The Adviser may identify opportunities in industries that appear to be temporarily depressed. The prices of securities in these industries may tend to go down more than those of companies in other industries. Since the Portfolio is not limited to investing in stocks, the Portfolio may own significant non-equity instruments in a rising stock market, thereby producing smaller gains than a fund invested solely in stocks. Because of the Portfolio’s disciplined and deliberate investing approach, there may be times when the Portfolio will have a significant cash position. A substantial cash position can adversely impact Portfolio performance in certain market conditions and may make it more difficult for the Portfolio to achieve its investment objective. <div style="display: none"></div> <p id="xdx_A8D_eoef--RiskTextBlock_hoef--RiskAxis__custom--SmallandMidCapRiskMember_zlTs32BJB0mb" style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify">Small- and Mid-Cap Risk. The Portfolio may invest from time to time in smaller and mid-size companies whose securities tend to be more volatile and less liquid than securities of larger companies. This can adversely affect the prices at which the Portfolio can purchase and sell these securities and, thus, the value of the Portfolio’s shares. <div style="display: none"></div> Commodities Risk. Prices of commodities such as timber and oil have historically been very volatile. Reductions in commodity prices will likely cause the prices of the securities of companies associated with the production of those commodities to decline. <div style="display: none"></div> <p id="xdx_A8B_eoef--RiskTextBlock_hoef--RiskAxis__custom--ForeignSecuritiesandEmergingMarketsRiskMember_ze5d513jJqz2" style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify">Foreign Securities and Emerging Markets Risk. Foreign securities from a particular country or region may be subject to currency fluctuations and controls, or adverse political, social, economic or other developments that are unique to that particular country or region. Therefore, the prices of foreign securities in particular countries or regions may, at times, move in a different direction than those of U.S. securities. Emerging market countries can generally have economic structures that are less diverse and mature, and political systems that are less stable, than those of developed countries, and, as a result, the securities markets of emerging markets countries can be more volatile than more developed markets may be. U.S. securities and accounting regulatory agencies continue to express concern regarding information access and audit quality regarding issuers in China and other emerging market countries, which could present heightened risks associated with investments in these markets. <div style="display: none"></div> Currency Risk. The Portfolio’s investments are usually denominated in or tied to the currencies of the countries in which they are primarily traded. Because the Portfolio may determine not to hedge its foreign currency risk, the U.S. Dollar value of the Portfolio’s investments may be harmed by declines in the value of foreign currencies in relation to the U.S. Dollar. <div style="display: none"></div> <p id="xdx_A8A_eoef--RiskTextBlock_hoef--RiskAxis__custom--CurrencyHedgingRiskMember_z9qmwnxoHcW7" style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify">Currency Hedging Risk. The Adviser may seek to hedge all or a portion of the Portfolio’s foreign currency risk. However, the Adviser cannot guarantee that it will be practical to hedge these risks in certain markets or conditions or that any efforts to do so will be successful. <div style="display: none"></div> Japanese Securities Risk. The Japanese economy has only recently emerged from a prolonged economic downturn. Since the year 2000, Japan’s economic growth rate has remained relatively low. The Japanese economy is characterized by an aging demographic, declining population, large government debt and highly regulated labor market. Economic growth in Japan is dependent on domestic consumption, deregulation and consistent government policy. International trade, particularly with the U.S., also impacts growth of the Japanese economy, and adverse economic conditions in the U.S. or other trade partners may affect Japan. Canadian Securities Risk. The Portfolio may invest in, and/or have exposure to, Canadian securities. The Canadian economy may be significantly affected by the U.S. economy because the U.S. is Canada’s largest trading partner and foreign investor. Canada’s largest exports are its natural resources, so the Canadian economy is dependent on the demand for, and supply and price of, natural resources, and any market developments that reduce the price of such goods could disproportionately affect the Canadian economy. <div style="display: none"></div> Liquidity Risk. Liquidity risk exists when particular investments are difficult to sell. The Portfolio may not be able to sell these investments at the best prices or at the value the Portfolio places on them. In such a market, the value of such investments and the Portfolio’s share price may fall dramatically. Investments that are illiquid or that trade in lower volumes may be more difficult to value. The market for high-yield debt securities (“junk bonds”) may be less liquid and therefore these securities may be harder to value or sell at an acceptable price, especially during times of market volatility or decline. Investments in foreign securities tend to have greater exposure to liquidity risk than U.S. securities. Liquidity can decline unpredictably in response to overall economic conditions or credit tightening. An unexpected increase in Portfolio redemption requests, including requests from Participating Insurance Companies who may own a significant percentage of the Portfolio’s shares, could cause the Portfolio to sell its holdings at a loss or at undesirable prices and adversely affect the Portfolio’s share price and increase the Portfolio’s liquidity risk and/or Portfolio expenses. <div style="display: none"></div> <p id="xdx_A84_eoef--RiskTextBlock_hoef--RiskAxis__custom--DebtSecuritiesRiskMember_zRbN5MvEGfQc" style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify">Debt Securities Risk. The market value of a debt security may decline due to general market conditions that are not specifically related to a particular company, such as real or perceived adverse economic conditions, changes in the outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. The debt securities market can be susceptible to increases in volatility and decreases in liquidity. Increases in volatility and decreases in liquidity may be caused by a rise in interest rates (or the expectation of a rise in interest rates). Prices of bonds and other debt securities tend to move inversely with changes in interest rates. Typically, a rise in rates will adversely affect debt securities and, accordingly, will cause the value of the Portfolio’s investments in these securities to decline. When interest rates fall, the values of already-issued securities generally rise, although investments in new securities may be at lower yields. The prices of high-yield debt securities (“junk bonds”), unlike investment grade debt securities, may fluctuate unpredictably and not necessarily inversely with changes in interest rates. Economic and other developments can adversely affect debt securities markets. <div style="display: none"></div> High-Yield Risk. The Portfolio’s investments in high-yield debt securities (commonly known as “junk bonds”) may expose the Portfolio to greater risks than if the Portfolio only owned higher-grade securities. The value of high-yield, lower quality securities is affected by the creditworthiness of the issuers of the securities and by general economic and specific industry conditions. Issuers of high-yield securities are not as strong financially as issuers of securities with higher credit ratings, so the securities are usually considered speculative investments. <div style="display: none"></div> <p id="xdx_A82_eoef--RiskTextBlock_hoef--RiskAxis__custom--InsolvencyandBankruptcyRiskMember_zNjrCrEiXlbe" style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify">Insolvency and Bankruptcy Risk. The Portfolio’s investments in obligations of stressed, distressed and bankrupt issuers, or those in conservatorship, including debt and preferred equity obligations that are in default, generally trade significantly below par and are considered speculative. There is even a potential risk of loss by the Portfolio of its entire investment in such securities. There are a number of significant risks inherent in the bankruptcy process. A bankruptcy filing by an issuer may adversely and permanently affect the market position and operations of the issuer. The Adviser, on behalf of the Portfolio, may also participate on committees formed by creditors to negotiate with debtors with respect to restructuring issues. There can be no assurance that the Adviser’s participation would yield favorable results for the Portfolio, and such participation may subject the Portfolio to additional duties, liabilities and trading restrictions in a particular investment. <div style="display: none"></div> <p id="xdx_A88_eoef--RiskTextBlock_hoef--RiskAxis__custom--FocusedInvestingRiskMember_z6QiukGS9hIi" style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify">Focused Investing Risk. Although the Portfolio is classified as a diversified investment company under the Investment Company Act of 1940, as amended (“1940 Act”), the Portfolio’s investments will normally be more focused than its peers and may emphasize investments in some issuers, industries, sectors or geographic regions more than others. To the extent that the Portfolio increases the relative emphasis of its investments in a particular issuer, industry, sector or geographic region, its share values may fluctuate in response to events affecting such issuer, industry, sector or geographic region. The Portfolio does not lose its status as a diversified investment company because of any subsequent discrepancy between the value of its various investments and the diversification requirements of the 1940 Act, so long as any such discrepancy existing immediately after the Portfolio’s acquisition of any security or other property is neither wholly nor partly the result of such acquisition. Therefore, the Portfolio from time to time may be considered “non-diversified” by the 1940 Act despite its classification as a diversified investment company. Performance The following bar chart and table provide an indication of the risks of investing in the Portfolio. The bar chart shows changes in the Portfolio’s performance from year to year for the past 10 years. The table compares the Portfolio’s average annual total returns to broad measure of market performance. These figures do not reflect charges assessed at the contract or separate account level. If any such charges were included, returns would be lower. The Portfolio’s past performance is not necessarily an indication of how the Portfolio will perform in the future.

The Adviser’s recovery is limited to the lesser of the expense limitation at the time of the waiver and the time of recapture. The Expense Limitation Agreement can only be amended by agreement of the Portfolio’s investment adviser and Independent board members to lower Net Annual Portfolio Operating Expenses and will terminate automatically in the event of termination of the Investment Management Agreement by one of the parties, effective upon the effectiveness of such termination.
