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

(1)The Manager has contractually agreed until July 31, 2025 to waive such portion of the management fees that it would otherwise receive under its agreement with Pear Tree Funds for serving as investment manager to Quality Fund such that the aggregate management fee that the Manager would receive during the waiver period for serving as the investment manager to Quality Fund would be calculated using (a) an annual rate of 0.75 percent for the first $125 million of Quality Fund's net assets, and (b) an annual rate of 0.50 percent for Quality Fund's net assets in excess of $125 million. This fee waiver only may be terminated with the approval of the Trustees. The Manager does not have a right to recoup from Quality Fund amounts that it has waived under that agreement.

Example

This example is intended to help you compare the cost of investing in Quality Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in Quality 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 percent return each year and that Quality Fund's operating expenses remain the same as set forth in the table above. The example also assumes that the fee waiver and expense reimbursement agreements currently in effect expire July 31, 2025; therefore, amounts for 3-, 5- and 10-year periods do not include any adjustment to reflect any fee waivers or expense reimbursements. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Portfolio Turnover

Quality 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 Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect Quality Fund's performance. During the most recent fiscal year, Quality Fund's portfolio turnover rate was 23 percent of the average value of its portfolio.

Principal Investment Strategies

Under normal market conditions, Quality Fund invests at least 80 percent of its net assets (plus any borrowings for investment purposes) in equity securities of U.S. issuers. Quality Fund principally invests in equity securities of large companies, that is, companies with a market capitalization of greater than $5 billion at time of purchase. However, there is no minimum market capitalization for companies whose securities Quality Fund may purchase.

To manage Quality Fund's portfolio, Quality Fund's investment manager, in consultation with its sub-adviser, periodically selects what it believes is a well-managed mutual fund (the "target portfolio"). Among the criteria used to select the target portfolio are the limited availability of the target portfolio to retail investors and the target portfolio's historical performance. Quality Fund's portfolio is then managed such that each quarter, its portfolio generally is rebalanced to comprise the same securities and in the same percentages as the target portfolio as of the end of the target portfolio's most recent fiscal quarter. If Quality Fund's assets significantly increase, Quality Fund may select more than one target portfolio.

From time to time, a target portfolio may invest in non-U.S. securities. In such cases, Quality Fund typically invests in American Depositary Receipts (or ADRs), which represent interests in such securities, if available. Quality Fund is "non-diversified," which means that it may invest a higher percentage of its assets in a smaller number of issuers.

Quality Fund's current target portfolio is GMO Quality Fund Class III (ticker symbol: GQETX). The current target portfolio purports to seek to generate total return by investing primarily in equities the target portfolio's investment manager believes to be of high quality, which it defines as companies with established track records of historical profitability and strong fundamentals. Neither Quality Fund, nor its investment manager, nor its sub-adviser, is affiliated with the current target portfolio or the current target portfolio's investment manager.

Quality Fund also may invest in derivatives (i.e., a security or instrument with a value that is determined by reference to the value or the change in value of one or more securities, currencies, indices or other financial instruments) for the purpose of hedging the value of the portfolio or to establish a position in the future. Quality Fund may hold cash, or it may manage its cash by investing in cash equivalents and money market funds.

Principal Investment Risks

It is possible to lose money by investing in Quality Fund. An investment in Quality Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Market, Industry and Specific Holdings. The share price of Quality Fund may fall because of weakness in and external shocks to the stock markets, generally, weakness with respect to a particular industry in which Quality Fund has significant holdings, or weaknesses associated with one or more specific companies in which Quality Fund may have substantial investments.

Difficulty in Comparing Fund Performance with Target Portfolio Performance. Quality Fund's performance could significantly differ from the target portfolio's performance over the same period. Among other things, the holdings of the target portfolio typically change - sometimes significantly during the period between the end of a quarter and the time when those changes are publicly disclosed and Quality Fund's portfolio is rebalanced. From time to time, Quality Fund may be purchasing specific securities at the same time that the target portfolio is selling them. In addition, the target portfolio has a significantly larger amount of assets than Quality Fund and thus, has a lower expense ratio than Quality Fund.

Inability to Conduct Due Diligence on Target Portfolio's Investment Adviser.  Quality Fund's investment manager and sub-adviser may be able to perform only limited due diligence on the target portfolio's investment adviser to determine, among other things, whether the investment adviser is adhering to the target portfolio's investment guidelines and whether the risks disclosed in the target portfolio's offering documents reflect the risks of the target portfolio.

Potential Impact on Target Portfolio. Quality Fund's purchases and sales of securities for its own portfolio may adversely impact the management of the target portfolio and thus, Quality Fund itself.

Accuracy of Target Portfolio Information. Any failure by a target portfolio to file accurate and timely portfolio information could affect the performance of Quality Fund.

Large- and Mid-Capitalization Securities. Securities issued by large- and mid-cap companies tend to be less volatile than securities issued by smaller companies. Larger companies, however, may not be able to attain the high growth rates of

5

successful smaller companies, especially during strong economic periods, and may be unable to respond as quickly to competitive challenges.

Foreign Securities.  Quality Fund's investments in or exposure to foreign securities (primarily through ADRs, securities traded on non-U.S. exchanges) and foreign securities traded on U.S. exchanges may be adversely affected by political and economic conditions overseas, reduced market liquidity, or decreases in foreign currency values relative to the U.S. dollar. The value of a foreign security may change materially at times when U.S. markets are not open to trading.

Non-Diversification.  Quality Fund is "non-diversified," As a result, a decline in the value of the securities of one issuer could have a significant negative effect on Quality Fund.

Specific Industry, Sector Concentration. Quality Fund may have significant investments in companies in a specific industry or groups of industries (a group of industries is also known as a "sector"), subjecting it to risks of that industry or sector, which may be greater than general market risk.

Liquidity Risk.  To meet shareholder redemption requests and other cash requirements, Quality Fund may have to sell certain portfolio securities at times when there may be few, if any, buyers, causing Quality Fund to accept sale prices below the amounts that had been used by the fund to determine its net asset value.

Derivatives.  Quality Fund's investments in derivative instruments are subject to a number of risks, such as counterparty risk, the risk of mispricing or improper valuation, and the risk that the value of the instrument may not increase or decrease as expected.

Cybersecurity and Technology Risk.  Quality Fund, its service providers, and other market participants increasingly depend on complex information technology and communications systems, which are subject to different threats and risks that could adversely affect Quality Fund and its shareholders. Cybersecurity and other operational and technology issues may result in financial losses to Quality Fund and its shareholders.
