Strategy [Heading]	<span style="color:#000000;font-family:Arial Narrow;font-size:11pt;font-weight:bold;">What are the Fund’s main investment strategies?</span>
Strategy Narrative [Text Block]	Drawing on a variety of analytical tools, the Fund’s adviser typically seeks to invest the Fund’s assets among various types of asset classes which include the following allocations: ●35%–80% equity securities ●15%–65% fixed income securities ●0-10% alternative securities ●0%–10% convertible securitiesThe Fund invests in separate underlying strategies by investing directly in individual securities, in other mutual funds and exchange traded funds (ETFs) within the same group of investment companies (J.P. Morgan Funds), and for the limited purposes described below, in passive ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs). The Fund may also invest in unaffiliated closed-end registered investment companies and other pooled investment vehicles (collectively with J.P. Morgan Funds and unaffiliated ETFs, underlying funds), across asset classes, including: U.S. equity and developed international equity across market capitalizations, emerging markets equity, domestic and foreign fixed income, high yield fixed income, emerging markets debt, and real estate investment trusts (REITs). A passive ETF is a registered investment company that seeks to track the performance of a particular market index. These indices include not only broad-based market indices but more specific indices as well, including those relating to particular sectors, markets, factors, regions or industries. The adviser may periodically increase or decrease the Fund’s actual asset allocations according to the relative attractiveness of each asset class. Within its equity allocations, the Fund invests primarily in the common stock of U.S. and foreign companies, REITs, and underlying funds primarily invest in such securities. Within its fixed income allocations, the Fund invests primarily in corporate bonds, asset-backed, mortgage- related and mortgage-backed securities, U.S. and foreign government securities, loan assignments and participations (Loans) and commitments to purchase loan assignments, emerging market debt and underlying funds that primarily invest in such securities.The Fund may invest in fixed income securities of any credit quality but may only invest up to 25% of its total assets in certain below investment grade securities (also known as high yield securities or junk bonds). This limit on below investment grade securities will include all investments held either directly by the Fund or in underlying funds held by the Fund which invest primarily in below investment grade securities (as disclosed in the underlying fund’s prospectus). In addition, the Fund may invest in underlying funds that may invest in fixed income securities of various credit qualities, including at times below investment grade securities, in order to expose the Fund to certain asset classes, such as emerging market debt. The remainder of the fixed income allocation will be invested directly in securities that, at the time of purchase are rated investment grade by a nationally recognized statistical rating organization or in securities that are unrated but are deemed by the Fund’s adviser to be of comparable quality. The Fund may invest in fixed income securities of any average weighted maturity or duration. The Fund may invest up to 30% of its total assets in shares of equity or fixed income underlying funds in order to expose the Fund to certain asset classes. To the extent the Fund invests in underlying funds, the adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For both actively-managed underlying funds and ETFs, the adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the adviser expects to invest in affiliated ETFs that are J.P. Morgan Funds (J.P. Morgan ETFs), unless the adviser determines the investment is not available. To the extent the adviser determines in its sole discretion that an investment in a passive J.P. Morgan ETF is not available, only then will the adviser consider an unaffiliated passive ETF. In addition, the Fund may seek to gain passive exposure to one or more markets by investing directly in the securities underlying a particular index. The Fund may also invest up to 10% of its assets in convertible securities. Additionally, the Fund may also invest up to 10% of its securities in alternative securities. The Fund's alternative securities investments may include individual securities, investments in underlying funds, and other pooled investment vehicles, including vehicles that hold or provide exposure to commodities, currencies or commodity futures. In addition to investments in underlying funds and direct investments in securities, the Fund may use derivatives, which are instruments that have a value based on another instrument, exchange rate or index, as substitutes for securities in which the Fund can invest. The Fund may use futures contracts, options, and swaps to more effectively gain targeted equity and fixed income exposure from its cash positions, to hedge investments, for risk management and to attempt to increase the Fund’s returns. The Fund may use futures contracts, options (including options on interest rate futures contracts and interest rate swaps), swaps, and credit default swaps to help manage duration, sector and yield curve exposure and credit and spread volatility. The Fund may utilize exchange traded futures contracts for cash management and to gain exposure to equities pending investment in individual securities. The Fund may invest in securities denominated in any currency. The Fund may also utilize foreign currency derivatives such as forward currency transactions to hedge exposure to non-dollar investments back to the U.S. dollar, as well as to gain exposure to certain currencies. Although the Fund will generally maintain its assets within the allocations above, the Fund may hold cash or cash equivalents for various purposes, including in connection with segregation for derivatives transactions, as collateral for derivatives transactions or for temporary defensive purposes. The adviser establishes the strategic and tactical allocation for the Fund and makes the day-to-day decisions concerning strategies and overall construction of the Fund. As attractive investments arise across asset classes and strategies, the adviser attempts to capture these opportunities by allocating the Fund’s assets among strategies and asset classes within pre-defined ranges. Investment decisions within strategies and asset classes are implemented either by the portfolio managers of the Fund’s underlying strategies who select individual securities for the Fund or with the Fund’s purchase of underlying funds. The frequency with which the Fund buys and sells underlying investments will vary from year to year, depending on, but not limited to: market conditions, performance of the underlying investments, and changes in the adviser’s investment views.

Strategy [Heading]	<span style="color:#000000;font-family:Arial Narrow;font-size:11pt;font-weight:bold;">What are the Fund’s main investment strategies?</span>
Strategy Narrative [Text Block]	The Fund seeks to provide capital appreciation through participation in the broad equity markets while hedging overall market exposure relative to traditional long-only equity strategies.Under normal circumstances, the Fund invests at least 80% of its Assets in equity securities.Equity securities represent an ownership interest in the issuer. The Fund invests in equity securities, which primarily consist of common stocks of large cap U.S. companies. The Fund will also purchase and sell exchange traded put options and sell exchange traded call options, employing an options overlay known as a “Put/Spread Collar” strategy, designed to provide a continuous market hedge for the portfolio. The options will typically be based on the S&P 500 Index (the Index) or on exchange-traded funds (ETFs) that replicate the S&P 500 Index (S&P 500 ETFs). The combination of the diversified portfolio of equity securities, combined with the options overlay, is intended to provide the Fund with a significant portion of the returns associated with equity market investments, while exposing investors to less risk than traditional long-only equity strategies. “Assets” means net assets plus the amount of borrowings for investment purposes. Volatility is one way to measure risk and refers to the variability of the Fund’s or the market’s returns. The Fund seeks to provide a competitive risk-adjusted return over a full market cycle (defined as three to five years) relative to the S&P 500 Total Return Index with lower volatility than traditional long-only equity strategies. The Fund typically holds options for three month periods (each, an “hedge period”) for the purpose of seeking to provide more predictable returns in any market cycle during the applicable hedge period. The put option spread is generally maintained at a level intended to reduce the Fund's exposure to a market decline by offsetting losses resulting from a decrease in the market. As a result of writing call options to offset the costs associated with the put option spread, some upside may be foregone in certain market environments. The quarterly hedge periods are based on returns from the first business day of January through the last business day of March; the first business day of April through the last business day of June; the first business day of July through the last business day of September; and the first business day of October through the last business day of December. The Fund’s investments in equity securities will be primarily in common stocks of U.S. companies with market capitalizations similar to those within the universe of the Index. As of the reconstitution of the Index on September 30, 2026, the market capitalizations of the companies in the Index ranged from $6.20 billion to $5.50 trillion. The Fund may also invest in equity securities of U.S. mid cap companies. The adviser’s process focuses on stock selection and tends to maintain sector weightings comparable to those of the broad U.S. large cap market. Within each sector, however, the Fund modestly overweights equity securities that it considers undervalued or fairly valued while modestly underweighting or not holding equity securities that appear overvalued. The Fund constructs a Put/Spread Collar by buying a put option on the Index at a higher strike price and writing (or selling) a put option on the Index at a relatively lower strike price, resulting in what is known as a put option spread, while simultaneously selling an Index call option. The Fund may need to construct additional Put/Spread Collars if the size of the Fund increases, either through purchases or appreciation. The Fund’s options overlay strategy is intended to provide the Fund with downside protection, while foregoing some upside potential. A put option spread seeks to protect the Fund against a decline in price, but only to the extent of the difference between the strike prices of the put option purchased and the put option sold. Entering into put option spreads is typically less expensive than a strategy of only purchasing put options and may benefit the Fund in a flat to upwardly moving market by reducing the cost of the downside protection; the downside protection of the put option spread, however, is limited as compared to just owning a put option. The premiums received from writing index call options are intended to provide income which substantially offsets the cost of the put option spread, but writing the options also reduces the Fund’s ability to profit from increases in the value of its equity portfolio because in rising markets the call option will be exercised once the market price rises to the option’s strike price. While the Fund typically constructs the Put/Spread Collar utilizing index options, it may also construct the Put/Spread Collar utilizing options on S&P 500 ETFs. The Fund’s investment strategies may not always provide greater market protection than other equity investments, particularly in rising equity markets when the Fund is expected to underperform traditional long-only equity strategies. In addition, as a result of selling call options to offset the costs associated with the options overlay strategy, some upside may be foregone in certain market environments. While the Fund will not generally invest directly in ETFs, there may be times when it will purchase shares or receive shares of S&P 500 ETFs in order to settle its options positions. The adviser will not normally maintain such positions for an extended period. Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for investments in certain securities. In addition to the use of the Put/Spread Collar strategy described above, the Fund may use derivatives, primarily futures contracts, to gain exposure to indexes or certain securities within indexes, to more effectively gain targeted equity exposure from its cash positions, and to hedge the Fund’s portfolio if it is unable to purchase or write the necessary options for its overlay strategy and efficient management of cash flows. To the extent the Fund invests in index futures with exposure to securities in the index, it may have the effect of increasing the Fund’s exposure to a relatively small number of securities, making the Fund’s shares more sensitive to the economic results of those securities. The Fund is also permitted to use other derivatives such as futures, options (including options on futures) and swaps in order to hedge various investments and for risk management. Under certain market conditions, the Fund's use of other derivatives for cash management or other investment management purposes could be significant. Investment Process —Equity Portfolio: With respect to the investment of the equity portfolio, the adviser employs a three-step process that combines research, valuation and stock selection. The adviser takes an in-depth look at company prospects over a period as long as five years, which is designed to provide insight into a company’s real growth potential. The research findings allow the adviser to rank the companies in each sector group according to their relative value. As part of its investment process, the adviser seeks to assess the impact of environmental, social and governance (ESG) factors on many issuers in the universe in which the Fund may invest. The adviser’s assessment is based on an analysis of key opportunities and risks across industries to seek to identify financially material issues with respect to the Fund’s investments in issuers and ascertain key issues that merit engagement with issuers. These assessments may not be conclusive, and securities of issuers that may be negatively impacted by such factors may be purchased and retained by the Fund while the Fund may divest or not invest in securities of issuers that may be positively impacted by such factors. On behalf of the Fund, the adviser then buys and sells equity securities, using the research and valuation rankings as a basis. In general, the adviser buys equity securities that are identified as attractive and considers selling them when they appear less attractive based on the Fund’s process. Along with attractive valuation, the adviser often considers a number of other criteria, including: ●catalysts, such as improving company fundamentals, that could trigger a rise in a stock’s price ●impact on the overall risk of the portfolio ●high perceived potential reward compared to perceived potential risk ●possible temporary mispricings caused by apparent market overreactions. Investment Process — Options Overlay Strategy: To implement the Put/Spread Collar strategy, the adviser utilizes exchange traded equity options based either on the Index or on S&P 500 ETFs. The Put/Spread Collar is constructed by buying a put option at a higher strike price while writing a put option at a relatively lower strike price and simultaneously selling a call option that substantially offsets the cost of the put option spread. The Put/Spread Collar strategy is an actively managed process and is designed to provide a continuous market hedge for the portfolio. The put option spread is generally maintained at a level intended to protect the Fund from a decrease in the market of 5% to 20%, with potential upside generally capped at 3.5-5.5%. The upside cap could be more or less, depending on market conditions. The options are systematically reset on at least a quarterly basis to better capitalize on current market conditions and opportunities while seeking to provide predictable returns in all market cycles.

Strategy Narrative [Text Block]	Under normal circumstances, the Fund invests at least 80% of its Assets in equity securities of U.S. companies.Equity securities represent an ownership interest in the issuer. In implementing its strategy, the Fund invests primarily in common stocks of large- and medium-capitalization U.S. companies but it may also invest up to 20% of its Assets in common stocks of foreign companies, including depositary receipts. Depositary receipts are financial instruments representing a foreign company’s publicly traded securities. A depositary receipt trades on a stock exchange in a country different from the company’s local market. “Assets” means net assets, plus the amount of borrowings for investment purposes. The Fund focuses on those equity securities that it considers attractively valued and seeks to outperform the Benchmark through superior stock selection. By emphasizing attractively valued equity securities, the Fund seeks to produce returns that exceed those of the Benchmark. Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for investments in certain securities. The Fund may use derivatives, primarily futures contracts, to gain exposure to its index or certain securities in its index, or to more effectively gain targeted equity exposure from its cash positions.

An issuer of a security will be deemed to be located in the United States if: (i) the principal trading market for the security is in the United States, (ii) the issuer is organized under the laws of the United States, or (iii) the issuer derives at least 50% of its revenues or profits from the United States or has at least 50% of its total assets situated in the United States.Investment Process: In managing the Fund, the adviser employs a three-step process that combines research, valuation and stock selection.

Strategy [Heading]	<span style="color:#000000;font-family:Arial Narrow;font-size:11pt;font-weight:bold;">What are the Fund’s main investment strategies?</span>
Strategy Narrative [Text Block]	Under normal circumstances, at least 80% of the value of the Fund’s Assets, which are expected to include both long and short positions, will consist of different U.S. securities, selected from a universe of publicly traded large capitalization securities with characteristics similar to those comprising the S&P 500 Index. The Fund takes long and short positions mainly in equity securities and derivatives on equity securities. “Assets” means net assets, plus the amount of borrowings for investment purposes. As of the reconstitution of the S&P 500 Index on September 30, 2026, the market capitalizations of the companies in the index ranged from $6.20 billion to $5.50 trillion.“Plus” in the Fund’s name refers to the additional return the Fund endeavors to add both relative to the S&P 500 Index as well as relative to traditional strategies which do not have the ability to sell stock short. Selling stock short allows the Fund to more fully exploit insights in stocks that the Fund’s adviser expects to underperform, as well as enabling the Fund to establish additional long positions while keeping the Fund’s net exposure to the market at a level similar to a traditional “long-only” strategy. Short sales involve the sale of a security which the fund does not own in expectation of purchasing the same security at a later date at a lower price. To make delivery to the buyer, the Fund must borrow the security, and the fund is obligated to return the security to the lender, which is accomplished by a later purchase of the security by the Fund. The Fund may also periodically short index futures in order to hedge its market exposure in instances when it is not preferable to enter into short positions on particular securities in the amount desired. The Fund intends to maintain an approximate net 100% long exposure to the equity market (long market value minus short market value). However the long and short positions held by the Fund will vary in size as market opportunities change. The Fund’s long positions and their equivalents will range between 90% and 150% of the value of the Fund’s net assets. The Fund’s short positions will range between 0% and 50% of the value of the Fund’s net assets. Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for investments in certain securities. The Fund currently intends to use swaps (including equity swaps) to establish its short equity positions, if any. The Fund may also use swaps to establish long equity positions, without owning or taking physical custody of securities. The payments received by the Fund under such swaps may be adjusted for transaction costs, interest payments, the amount of dividends paid on the investment or instrument or other factors. The Fund may also use futures contracts to gain exposure to its index or certain securities in its index, or to more effectively gain targeted equity exposure from its cash positions. To the extent the Fund invests in index futures with exposure to securities in the index, it may have the effect of increasing the Fund’s exposure to a relatively small number of securities, making the Fund’s shares more sensitive to the economic results of those securities. An issuer of a security will be deemed to be located in the United States if: (i) the principal trading market for the security is in the United States, (ii) the issuer is organized under the laws of the United States, or (iii) the issuer derives at least 50% of its revenues or profits from the United States or has at least 50% of its total assets situated in the United States.Investment Process: In managing the Fund, the adviser employs a three-step process that combines research, valuation and stock selection.

In general, the adviser buys and covers shorts in equity securities that are identified as undervalued and considers selling or shorting them when they appear overvalued. Along with attractive valuation, the adviser often considers a number of other criteria such as: ●catalysts that could trigger a rise in a stock’s price ●high potential reward compared to potential risk ●temporary mispricings caused by apparent market overreactions.The Fund’s investment strategies may involve active and frequent trading resulting in high portfolio turnover.

Strategy [Heading]	<span style="color:#000000;font-family:Arial Narrow;font-size:11pt;font-weight:bold;">What are the Fund’s main investment strategies?</span>
Strategy Narrative [Text Block]	In managing the Fund, the adviser identifies companies that, in the adviser’s opinion, are sustainable leaders based on its sustainability criteria, and have high quality, durable franchises which the adviser believes are attractively valued. The adviser’s sustainability criteria are based on a proprietary scoring methodology, which includes an assessment of environmental, social and corporate governance (ESG) characteristics, qualitative factors, and the adviser’s subjective judgment as to which companies are sustainable leaders. The Fund seeks to invest in companies that, on a combined basis, appear attractive when considering these sustainability and financial characteristics.The Fund defines ESG characteristics as follows: ●Environmental — companies that actively strive to reduce the negative impact of their business operations on the environment. In this context, the adviser analyzes factors such as the company’s likely impact on climate change, natural resource use, pollution and the use of clean technology ●Social — companies that consider the social impact of their business internally and externally. In this context, the adviser reviews considerations such as worker safety, product safety and integrity, healthier products, impact on the community and human rights ●Governance — companies that embrace corporate governance principles. In reviewing governance characteristics, the adviser considers issues such as board accountability and diversity, shareholder rights, executive compensation, business ethics and government and public policyThe Fund invests primarily in large-cap and mid-cap common stocks, and under normal circumstances, the Fund invests at least 80% of its Assets in the equity securities of U.S. companies meeting the adviser’s sustainability criteria. “Assets” means net assets, plus the amount of any borrowings for investment purposes. Because investing on the basis of sustainability/ESG criteria involves qualitative and subjective analysis, there can be no assurance that the methodology utilized by, or determinations made by, the adviser will align with the beliefs or values of a particular investor. Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for investments in certain securities. The Fund may use derivatives, primarily futures contracts, to gain or reduce exposure to its index or certain securities in its index, maintain liquidity, minimize transaction costs, or to more effectively gain targeted equity exposure from its cash positions. To the extent the Fund invests in index futures with exposure to securities in the index, it may have the effect of increasing the Fund’s exposure to a relatively small number of securities, making the Fund’s shares more sensitive to the economic results of those securities. In managing cash flows, the Fund buys futures contracts to invest incoming cash in the market or sells futures contracts in response to cash outflows, thereby gaining market exposure while maintaining a cash balance for liquidity. An issuer of a security will be deemed to be located in the U.S. if: (i) the principal trading market for the security is in the United States, (ii) the issuer is organized under the laws of the United States, or (iii) the issuer derives at least 50% of its revenues or profits from the United States or has at least 50% of its total assets situated in the U.S.Investment Process: The Fund has an actively managed strategy. In managing the Fund, the adviser employs a fundamental, bottom-up approach to stock selection, constructing portfolios based on company financials, data analysis and proprietary research. In choosing securities to purchase, the adviser evaluates and internally ranks companies to identify those companies that, in the adviser’s view, are sustainable leaders and have high quality, durable franchises, which the adviser believes are attractively valued. The adviser assesses sustainability based on fundamental analysis using a wide set of data inputs which may include proprietary research, information self-reported by companies, and third-party data. The adviser may vary the importance of particular ESG and investment characteristics by industry because, in the adviser’s judgment, certain characteristics are more relevant for certain industries. For example, an environmental characteristic, such as land use, may be more relevant for energy companies than for technology companies. In addition, the Fund seeks to avoid investing in companies that the adviser has determined, based on its exclusionary criteria, to be significantly involved in certain business activities or industries, including the production of tobacco, controversial weapons, traditional weapons, thermal coal, adult entertainment and gambling products and services, or to be violating certain norms-based criteria (for example, UN Global Compact violators). This exclusionary criteria relies on multiple data inputs, including information from third-party providers who identify an issuer’s participation in, or the revenue which they derive from, activities that are inconsistent with values- and norms-based screens. The adviser may modify the exclusionary criteria without notice to shareholders to, among other things, modify the data inputs, change third-party data providers, or add or remove certain business activities or industries from the screening process. The Fund has flexibility to focus in various industries or sectors based on the adviser’s analysis of market opportunities at a particular time. The Fund will sell a stock if the adviser determines that the issuer no longer meets the Fund’s investment criteria or if the adviser believes that more attractive opportunities are available.

Strategy Narrative [Text Block]	Under normal circumstances, the Fund will invest at least 80% of its Assets in common stocks issued by U.S. value companies.Value companies are those that the adviser believes are undervalued or attractively valued, based on one or more of the following factors: how the stock price compares to the company’s sales, earnings, and assets, as well as the overall value of the company compared to its sales and the capital invested in it. “Assets” means net assets, plus the amount of borrowings for investment purposes. The Fund’s adviser applies an active equity management style focused on identifying attractively valued securities given their growth potential over a long-term time horizon. The securities held by the Fund will predominantly be of companies with market capitalizations similar to those within the universe of the Russell 1000® Value Index (which includes both large cap and mid cap companies). As of September 30, 2026 the market capitalizations of the companies in the index ranged from $1.76 billion to $4.81 trillion. While common stocks are the Fund’s primary investment, the Fund may also invest significantly in real estate investment trusts (REITs) and depositary receipts. Depositary receipts are financial instruments representing a foreign company’s publicly traded securities. A depository receipt trades on a stock exchange in a country different from the company’s local market. Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions. An issuer of a security will be deemed to be located in the U.S. if: (i) the principal trading market for the security is in the United States, (ii) the issuer is organized under the laws of the United States, or (iii) the issuer derives at least 50% of its revenues or profits from the United States or has at least 50% of its total assets situated in the U.S.Investment Process: In managing the Fund, the adviser will emphasize companies which it believes are leaders within their sectors. The adviser will also emphasize companies it believes have attractive valuations and low price-to-cash flow ratios. Some but not all of the companies may regularly pay dividends. The adviser employs a bottom-up approach to stock selection, constructing portfolios based on company fundamentals, quantitative screening and proprietary fundamental analysis. The adviser's analysis includes a review of proprietary data, information self-reported by companies, data from third party vendors and internal fundamental research. The adviser looks for attractively valued companies with durable franchises, strong management and the ability to grow their intrinsic value per share. As part of its investment process, the adviser seeks to assess the impact of environmental, social and governance (ESG) factors on many issuers in the universe in which the Fund may invest. The adviser’s assessment is based on an analysis of key opportunities and risks across industries to seek to identify financially material issues with respect to the Fund’s investments in issuers and ascertain key issues that merit engagement with issuers. These assessments may not be conclusive, and securities of issuers that may be negatively impacted by such factors may be purchased and retained by the Fund while the Fund may divest or not invest in securities of issuers that may be positively impacted by such factors. The adviser may sell a security for several reasons. A security may be sold due to a change in the company’s fundamentals or if the adviser believes the security is no longer attractively valued. Investments may also be sold if the adviser identifies a stock that it believes offers a better investment opportunity.

Strategy Narrative [Text Block]	Under normal circumstances, the Fund invests at least 80% of its Assets in equity securities of mid cap companies.Equity securities represent an ownership interest in the issuer. Mid cap companies are companies with market capitalizations equal to those within the universe of the Russell Midcap® Index at the time of purchase. As of the reconstitution of the Russell Midcap Index on September 30, 2026, the market capitalizations of the companies in the index ranged from $1.76 billion to $251.61 billion.In implementing its main strategies, the Fund invests primarily in common stocks and real estate investment trusts (REITs). “Assets” means net assets, plus the amount of borrowings for investment purposes.Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions. Investment Process: In managing the Fund, the portfolio management team employs an investment process that seeks to identify both growth and value securities for the Fund. The team seeks to identify companies with leading competitive positions, talented management teams and durable business models. In addition, the team will invest in companies that it believes either have the capacity to achieve a sustainable level of above average growth or have sustainable free cash flow generation with management committed to increasing shareholder value.

Strategy Narrative [Text Block]	The Fund is a small cap equity portfolio which is normally managed as a core portfolio, but which has the ability to proactively invest more heavily in either growth or value securities depending on market conditions and the convictions of the adviser.The portfolio managers will consider various factors when making overall allocation decisions for the Fund, including the relative attractiveness of growth and value securities and the relative valuations and fundamentals of companies in the small cap growth and value universes. Based on these considerations, the size of the allocation of the Fund to either growth or value securities may range from 30 to 70 percent of the Fund. Under normal circumstances, the Fund invests at least 80% of its Assets in equity securities of small cap companies.Small cap companies are companies with market capitalizations equal to those within the universe of the Russell 2000® Index at the time of purchase. As of the reconstitution of the Russell 2000 Index on September 30, 2026, the market capitalizations of the companies in the index ranged from $5.62 million to $85.78 billion.

To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions. Investment Process: In managing the Fund, the Fund’s adviser seeks to outperform the Fund’s benchmark. The adviser employs a fundamental bottom-up investment process that combines research, valuation and stock selection to identify both growth and value securities. In selecting growth securities, the adviser seeks to invest in companies that have a history of above-average growth or that the adviser believes will achieve above-average growth in the future. The adviser believes that investing in high quality growth companies whose long-term growth rates are underappreciated by the market will lead to attractive returns. Growth companies purchased for the Fund include those with leading competitive positions, predictable and durable business models and management that can achieve sustained growth. In selecting value securities, the adviser seeks to invest in companies which have durable franchises and that the adviser believes to be attractively valued and to have the ability to grow intrinsic value per share. Companies with durable franchises generally have a sustainable competitive position relative to peers, high returns on capital, a diversified client or asset base and a strong brand.As part of its investment process, the adviser seeks to assess the impact of environmental, social and governance (ESG) factors on many issuers in the universe in which the Fund may invest.

Sector by sector, the Fund’s weightings are similar to those of the Russell 2000® Index. The Fund can moderately underweight or overweight sectors when it believes it will benefit performance. The Fund pursues returns that exceed those of the Russell 2000® Index while seeking to limit its volatility relative to this index. In implementing its main strategies, the Fund’s investments are primarily in common stocks and real estate investment trusts (REITs).Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. The Fund may use futures contracts to gain or reduce exposure to its index, maintain liquidity and minimize transaction costs. In managing cash flows, the Fund buys futures contracts to invest incoming cash in the market or sells futures contracts in response to cash outflows, thereby gaining market exposure to the index while maintaining a cash balance for liquidity. An issuer of a security will be deemed to be located in the United States if: (i) the principal trading market for the security is in the United States, (ii) the issuer is organized under the laws of the United States, or (iii) the issuer derives at least 50% of its revenues or profits from the United States or has at least 50% of its total assets situated in the United States.Investment Process: In managing the Fund, the adviser employs a process that ranks stocks based on its proprietary stock ranking system. The rankings are then reviewed and adjusted utilizing fundamental research conducted by the investment team to enhance accuracy and consistency. The adjusted rankings are used to place stocks into portfolios. As part of its investment process, the adviser seeks to assess the impact of environmental, social and governance (ESG) factors on many issuers in the universe in which the Fund may invest. The adviser’s assessment is based on an analysis of key opportunities and risks across industries to seek to identify financially material issues with respect to the Fund’s investments in issuers and ascertain key issues that merit engagement with issuers. These assessments may not be conclusive, and securities of issuers that may be negatively impacted by such factors may be purchased and retained by the Fund while the Fund may divest or not invest in securities of issuers that may be positively impacted by such factors. In general, stocks are purchased when they are among the top ranked within their sector. Stocks become candidates for sale when their ranking falls, when they appear unattractive or when the company is no longer a small cap company. The Fund may continue to hold the securities if it believes further substantial growth is possible. Risk factor exposures are managed through portfolio construction. Portfolio constraints control for sector weights, position sizes and/or style characteristics of the Fund.

Strategy Narrative [Text Block]	Drawing on a variety of analytical tools, the Fund’s adviser typically seeks to invest the Fund’s assets among various types of asset classes which include the following allocations: ●35%–80% equity securities ●15%–65% fixed income securities ●0-10% alternative securities ●0%–10% convertible securitiesThe Fund invests in separate underlying strategies by investing directly in individual securities, in other mutual funds and exchange traded funds (ETFs) within the same group of investment companies (J.P. Morgan Funds), and for the limited purposes described below, in passive ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs). The Fund may also invest in unaffiliated closed-end registered investment companies and other pooled investment vehicles (collectively with J.P. Morgan Funds and unaffiliated ETFs, underlying funds), across asset classes, including: U.S. equity and developed international equity across market capitalizations, emerging markets equity, domestic and foreign fixed income, high yield fixed income, emerging markets debt, and real estate investment trusts (REITs). A passive ETF is a registered investment company that seeks to track the performance of a particular market index. These indices include not only broad-based market indices but more specific indices as well, including those relating to particular sectors, markets, factors, regions or industries. The adviser may periodically increase or decrease the Fund’s actual asset allocations according to the relative attractiveness of each asset class. Within its equity allocations, the Fund invests primarily in the common stock of U.S. and foreign companies, REITs, and underlying funds primarily invest in such securities. Within its fixed income allocations, the Fund invests primarily in corporate bonds, asset-backed, mortgage- related and mortgage-backed securities, U.S. and foreign government securities, loan assignments and participations (Loans) and commitments to purchase loan assignments, emerging market debt and underlying funds that primarily invest in such securities.The Fund may invest in fixed income securities of any credit quality but may only invest up to 25% of its total assets in certain below investment grade securities (also known as high yield securities or junk bonds). This limit on below investment grade securities will include all investments held either directly by the Fund or in underlying funds held by the Fund which invest primarily in below investment grade securities (as disclosed in the underlying fund’s prospectus). In addition, the Fund may invest in underlying funds that may invest in fixed income securities of various credit qualities, including at times below investment grade securities, in order to expose the Fund to certain asset classes, such as emerging market debt. The remainder of the fixed income allocation will be invested directly in securities that, at the time of purchase are rated investment grade by a nationally recognized statistical rating organization or in securities that are unrated but are deemed by the Fund’s adviser to be of comparable quality. The Fund may invest in fixed income securities of any average weighted maturity or duration. The Fund may invest up to 30% of its total assets in shares of equity or fixed income underlying funds in order to expose the Fund to certain asset classes. To the extent the Fund invests in underlying funds, the adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For both actively-managed underlying funds and ETFs, the adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the adviser expects to invest in affiliated ETFs that are J.P. Morgan Funds (J.P. Morgan ETFs), unless the adviser determines the investment is not available. To the extent the adviser determines in its sole discretion that an investment in a passive J.P. Morgan ETF is not available, only then will the adviser consider an unaffiliated passive ETF. In addition, the Fund may seek to gain passive exposure to one or more markets by investing directly in the securities underlying a particular index. The Fund may also invest up to 10% of its assets in convertible securities. Additionally, the Fund may also invest up to 10% of its securities in alternative securities. The Fund's alternative securities investments may include individual securities, investments in underlying funds, and other pooled investment vehicles, including vehicles that hold or provide exposure to commodities, currencies or commodity futures. In addition to investments in underlying funds and direct investments in securities, the Fund may use derivatives, which are instruments that have a value based on another instrument, exchange rate or index, as substitutes for securities in which the Fund can invest. The Fund may use futures contracts, options, and swaps to more effectively gain targeted equity and fixed income exposure from its cash positions, to hedge investments, for risk management and to attempt to increase the Fund’s returns. The Fund may use futures contracts, options (including options on interest rate futures contracts and interest rate swaps), swaps, and credit default swaps to help manage duration, sector and yield curve exposure and credit and spread volatility. The Fund may utilize exchange traded futures contracts for cash management and to gain exposure to equities pending investment in individual securities. The Fund may invest in securities denominated in any currency. The Fund may also utilize foreign currency derivatives such as forward currency transactions to hedge exposure to non-dollar investments back to the U.S. dollar, as well as to gain exposure to certain currencies. Although the Fund will generally maintain its assets within the allocations above, the Fund may hold cash or cash equivalents for various purposes, including in connection with segregation for derivatives transactions, as collateral for derivatives transactions or for temporary defensive purposes. The adviser establishes the strategic and tactical allocation for the Fund and makes the day-to-day decisions concerning strategies and overall construction of the Fund. As attractive investments arise across asset classes and strategies, the adviser attempts to capture these opportunities by allocating the Fund’s assets among strategies and asset classes within pre-defined ranges. Investment decisions within strategies and asset classes are implemented either by the portfolio managers of the Fund’s underlying strategies who select individual securities for the Fund or with the Fund’s purchase of underlying funds. The frequency with which the Fund buys and sells underlying investments will vary from year to year, depending on, but not limited to: market conditions, performance of the underlying investments, and changes in the adviser’s investment views.

Strategy Narrative [Text Block]	Under normal circumstances, the Fund invests at least 80% of its Assets in equity securities of U.S. companies.Equity securities represent an ownership interest in the issuer. In implementing its strategy, the Fund invests primarily in common stocks of large- and medium-capitalization U.S. companies but it may also invest up to 20% of its Assets in common stocks of foreign companies, including depositary receipts. Depositary receipts are financial instruments representing a foreign company’s publicly traded securities. A depositary receipt trades on a stock exchange in a country different from the company’s local market. “Assets” means net assets, plus the amount of borrowings for investment purposes. The Fund focuses on those equity securities that it considers attractively valued and seeks to outperform the Benchmark through superior stock selection. By emphasizing attractively valued equity securities, the Fund seeks to produce returns that exceed those of the Benchmark. Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for investments in certain securities. The Fund may use derivatives, primarily futures contracts, to gain exposure to its index or certain securities in its index, or to more effectively gain targeted equity exposure from its cash positions. To the extent the Fund invests in index futures with exposure to securities in the index, it may have the effect of increasing the Fund’s exposure to a relatively small number of securities, making the Fund’s shares more sensitive to the economic results of those securities. An issuer of a security will be deemed to be located in the United States if: (i) the principal trading market for the security is in the United States, (ii) the issuer is organized under the laws of the United States, or (iii) the issuer derives at least 50% of its revenues or profits from the United States or has at least 50% of its total assets situated in the United States.Investment Process: In managing the Fund, the adviser employs a three-step process that combines research, valuation and stock selection. The adviser takes an in-depth look at company prospects, which is designed to provide insight into a company’s real growth potential. The research findings allow the adviser to rank the companies in each sector group according to their relative value. As part of its investment process, the adviser seeks to assess the impact of environmental, social and governance (ESG) factors on many issuers in the universe in which the Fund may invest. The adviser’s assessment is based on an analysis of key opportunities and risks across industries to seek to identify financially material issues with respect to the Fund’s investments in issuers and ascertain key issues that merit engagement with issuers. These assessments may not be conclusive, and securities of issuers that may be negatively impacted by such factors may be purchased and retained by the Fund while the Fund may divest or not invest in securities of issuers that may be positively impacted by such factors. On behalf of the Fund, the adviser then buys and sells equity securities, using the research and valuation rankings as a basis. In general, the adviser buys equity securities that are identified as attractively valued and considers selling them when they appear to be overvalued. Along with attractive valuation, the adviser often considers a number of other criteria: ●catalysts that could trigger a rise in a stock’s price ●high potential reward compared to potential risk ●temporary mispricings caused by apparent market over-reactions.

Strategy Narrative [Text Block]	Under normal circumstances, the Fund invests at least 80% of its Assets in equity securities of small cap U.S. companies.Small cap companies are companies with market capitalizations similar to those within the universe of the Russell 2000® Index at the time of purchase. As of the reconstitution of the Russell 2000 Index on September 30, 2026, the market capitalizations of the companies in the index ranged from $5.62 million to $85.78 billion. “Assets” means net assets, plus the amount of borrowings for investment purposes. Sector by sector, the Fund’s weightings are similar to those of the Russell 2000® Index. The Fund can moderately underweight or overweight sectors when it believes it will benefit performance. The Fund pursues returns that exceed those of the Russell 2000® Index while seeking to limit its volatility relative to this index. In implementing its main strategies, the Fund’s investments are primarily in common stocks and real estate investment trusts (REITs).Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. The Fund may use futures contracts to gain or reduce exposure to its index, maintain liquidity and minimize transaction costs. In managing cash flows, the Fund buys futures contracts to invest incoming cash in the market or sells futures contracts in response to cash outflows, thereby gaining market exposure to the index while maintaining a cash balance for liquidity. An issuer of a security will be deemed to be located in the United States if: (i) the principal trading market for the security is in the United States, (ii) the issuer is organized under the laws of the United States, or (iii) the issuer derives at least 50% of its revenues or profits from the United States or has at least 50% of its total assets situated in the United States.Investment Process: In managing the Fund, the adviser employs a process that ranks stocks based on its proprietary stock ranking system. The rankings are then reviewed and adjusted utilizing fundamental research conducted by the investment team to enhance accuracy and consistency. The adjusted rankings are used to place stocks into portfolios. As part of its investment process, the adviser seeks to assess the impact of environmental, social and governance (ESG) factors on many issuers in the universe in which the Fund may invest. The adviser’s assessment is based on an analysis of key opportunities and risks across industries to seek to identify financially material issues with respect to the Fund’s investments in issuers and ascertain key issues that merit engagement with issuers. These assessments may not be conclusive, and securities of issuers that may be negatively impacted by such factors may be purchased and retained by the Fund while the Fund may divest or not invest in securities of issuers that may be positively impacted by such factors. In general, stocks are purchased when they are among the top ranked within their sector. Stocks become candidates for sale when their ranking falls, when they appear unattractive or when the company is no longer a small cap company. The Fund may continue to hold the securities if it believes further substantial growth is possible. Risk factor exposures are managed through portfolio construction. Portfolio constraints control for sector weights, position sizes and/or style characteristics of the Fund.

Equity securities in which the Fund invests primarily include common stocks and real estate investment trusts (REITs). Under normal circumstances, the Fund will invest at least 80% of its Assets in securities of value companies.Value companies are those that the adviser believes are undervalued or attractively valued, based on one or more of the following factors: how the stock price compares to the company's sales, earnings, and assets, as well as the overall value of the company compared to its sales and the capital invested in it.“Assets” means net assets, plus the amount of any borrowings for investment purposes. Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions. Investment Process: In managing the Fund, the adviser employs a bottom-up approach to stock selection, constructing portfolios based on company fundamentals and proprietary fundamental analysis. The adviser’s aim is to identify attractively valued companies that have the potential to grow their intrinsic values per share and to purchase these companies at a discount. As part of its investment process, the adviser seeks to assess the impact of environmental, social and governance (ESG) factors on many issuers in the universe in which the Fund may invest.

The adviser may sell a security for several reasons. A security may be sold due to a change in the company’s fundamentals or if the adviser believes the security is no longer attractively valued. Investments may also be sold if the adviser identifies a stock that it believes offers a better investment opportunity.

Strategy Narrative [Text Block]	Under normal circumstances, the Fund invests at least 80% of its Assets in equity securities of U.S. companies. “Assets” means net assets plus the amount of borrowings for investment purposes. In implementing this strategy, the Fund invests primarily in the common stocks of U.S. companies in the S&P 500 Index (which includes both large cap and mid cap companies). The Fund may also invest in securities not included within the S&P 500 Index. As of the reconstitution of the S&P 500 Index on September 30, 2026, the market capitalizations of the companies in the index ranged from $6.20 billion to $5.50 trillion. Sector by sector, the Fund’s weightings are similar to those of the S&P 500 Index. Within each sector, the Fund modestly overweights equity securities that it considers undervalued or fairly valued while modestly underweighting or not holding equity securities that appear overvalued. By owning a large number of equity securities within the S&P 500 Index, with an emphasis on those that appear undervalued or fairly valued, the Fund seeks returns that modestly exceed those of the S&P 500 Index over the long term with a modest level of volatility. Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for investments in certain securities. The Fund may use derivatives, primarily futures contracts, to gain exposure to its index or certain securities in its index, or to more effectively gain targeted equity exposure from its cash positions.

The adviser takes an in-depth look at company prospects, which is designed to provide insight into a company’s real growth potential. The research findings allow the adviser to rank the companies in each sector group according to their relative value. As part of its investment process, the adviser seeks to assess the impact of environmental, social and governance (ESG) factors on many issuers in the universe in which the Fund may invest. The adviser’s assessment is based on an analysis of key opportunities and risks across industries to seek to identify financially material issues with respect to the Fund’s investments in issuers and ascertain key issues that merit engagement with issuers. These assessments may not be conclusive, and securities of issuers that may be negatively impacted by such factors may be purchased and retained by the Fund while the Fund may divest or not invest in securities of issuers that may be positively impacted by such factors. The Fund is non-diversified and may invest a greater percentage of its assets in a particular issuer or group of issuers than a diversified fund would. On behalf of the Fund, the adviser then buys and sells equity securities, using the research and valuation rankings as a basis. Along with attractive valuation, the adviser often considers a number of other criteria: ●catalysts that could trigger a rise in a stock’s price ●impact on the overall risk of the portfolio relative to the S&P 500 Index ●high perceived potential reward compared to perceived potential risk ●possible temporary mispricings caused by apparent market overreactions The adviser may sell a security as its valuations or rankings change or if more attractive investments become available.

Strategy Narrative [Text Block]	Drawing on a variety of analytical tools, the Fund’s adviser typically seeks to invest the Fund’s assets among various types of asset classes which include the following allocations: ●35%–80% equity securities ●15%–65% fixed income securities ●0-10% alternative securities ●0%–10% convertible securitiesThe Fund invests in separate underlying strategies by investing directly in individual securities, in other mutual funds and exchange traded funds (ETFs) within the same group of investment companies (J.P. Morgan Funds), and for the limited purposes described below, in passive ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs). The Fund may also invest in unaffiliated closed-end registered investment companies and other pooled investment vehicles (collectively with J.P. Morgan Funds and unaffiliated ETFs, underlying funds), across asset classes, including: U.S. equity and developed international equity across market capitalizations, emerging markets equity, domestic and foreign fixed income, high yield fixed income, emerging markets debt, and real estate investment trusts (REITs). A passive ETF is a registered investment company that seeks to track the performance of a particular market index. These indices include not only broad-based market indices but more specific indices as well, including those relating to particular sectors, markets, factors, regions or industries. The adviser may periodically increase or decrease the Fund’s actual asset allocations according to the relative attractiveness of each asset class. Within its equity allocations, the Fund invests primarily in the common stock of U.S. and foreign companies, REITs, and underlying funds primarily invest in such securities. Within its fixed income allocations, the Fund invests primarily in corporate bonds, asset-backed, mortgage- related and mortgage-backed securities, U.S. and foreign government securities, loan assignments and participations (Loans) and commitments to purchase loan assignments, emerging market debt and underlying funds that primarily invest in such securities.The Fund may invest in fixed income securities of any credit quality but may only invest up to 25% of its total assets in certain below investment grade securities (also known as high yield securities or junk bonds). This limit on below investment grade securities will include all investments held either directly by the Fund or in underlying funds held by the Fund which invest primarily in below investment grade securities (as disclosed in the underlying fund’s prospectus). In addition, the Fund may invest in underlying funds that may invest in fixed income securities of various credit qualities, including at times below investment grade securities, in order to expose the Fund to certain asset classes, such as emerging market debt. The remainder of the fixed income allocation will be invested directly in securities that, at the time of purchase are rated investment grade by a nationally recognized statistical rating organization or in securities that are unrated but are deemed by the Fund’s adviser to be of comparable quality. The Fund may invest in fixed income securities of any average weighted maturity or duration. The Fund may invest up to 30% of its total assets in shares of equity or fixed income underlying funds in order to expose the Fund to certain asset classes. To the extent the Fund invests in underlying funds, the adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For both actively-managed underlying funds and ETFs, the adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the adviser expects to invest in affiliated ETFs that are J.P. Morgan Funds (J.P. Morgan ETFs), unless the adviser determines the investment is not available. To the extent the adviser determines in its sole discretion that an investment in a passive J.P. Morgan ETF is not available, only then will the adviser consider an unaffiliated passive ETF. In addition, the Fund may seek to gain passive exposure to one or more markets by investing directly in the securities underlying a particular index. The Fund may also invest up to 10% of its assets in convertible securities. Additionally, the Fund may also invest up to 10% of its securities in alternative securities. The Fund's alternative securities investments may include individual securities, investments in underlying funds, and other pooled investment vehicles, including vehicles that hold or provide exposure to commodities, currencies or commodity futures. In addition to investments in underlying funds and direct investments in securities, the Fund may use derivatives, which are instruments that have a value based on another instrument, exchange rate or index, as substitutes for securities in which the Fund can invest. The Fund may use futures contracts, options, and swaps to more effectively gain targeted equity and fixed income exposure from its cash positions, to hedge investments, for risk management and to attempt to increase the Fund’s returns. The Fund may use futures contracts, options (including options on interest rate futures contracts and interest rate swaps), swaps, and credit default swaps to help manage duration, sector and yield curve exposure and credit and spread volatility. The Fund may utilize exchange traded futures contracts for cash management and to gain exposure to equities pending investment in individual securities. The Fund may invest in securities denominated in any currency. The Fund may also utilize foreign currency derivatives such as forward currency transactions to hedge exposure to non-dollar investments back to the U.S. dollar, as well as to gain exposure to certain currencies. Although the Fund will generally maintain its assets within the allocations above, the Fund may hold cash or cash equivalents for various purposes, including in connection with segregation for derivatives transactions, as collateral for derivatives transactions or for temporary defensive purposes. The adviser establishes the strategic and tactical allocation for the Fund and makes the day-to-day decisions concerning strategies and overall construction of the Fund. As attractive investments arise across asset classes and strategies, the adviser attempts to capture these opportunities by allocating the Fund’s assets among strategies and asset classes within pre-defined ranges. Investment decisions within strategies and asset classes are implemented either by the portfolio managers of the Fund’s underlying strategies who select individual securities for the Fund or with the Fund’s purchase of underlying funds. The frequency with which the Fund buys and sells underlying investments will vary from year to year, depending on, but not limited to: market conditions, performance of the underlying investments, and changes in the adviser’s investment views.

Strategy Narrative [Text Block]	In managing the Fund, the adviser identifies companies that, in the adviser’s opinion, are sustainable leaders based on its sustainability criteria, and have high quality, durable franchises which the adviser believes are attractively valued. The adviser’s sustainability criteria are based on a proprietary scoring methodology, which includes an assessment of environmental, social and corporate governance (ESG) characteristics, qualitative factors, and the adviser’s subjective judgment as to which companies are sustainable leaders. The Fund seeks to invest in companies that, on a combined basis, appear attractive when considering these sustainability and financial characteristics.The Fund defines ESG characteristics as follows: ●Environmental — companies that actively strive to reduce the negative impact of their business operations on the environment. In this context, the adviser analyzes factors such as the company’s likely impact on climate change, natural resource use, pollution and the use of clean technology ●Social — companies that consider the social impact of their business internally and externally. In this context, the adviser reviews considerations such as worker safety, product safety and integrity, healthier products, impact on the community and human rights ●Governance — companies that embrace corporate governance principles. In reviewing governance characteristics, the adviser considers issues such as board accountability and diversity, shareholder rights, executive compensation, business ethics and government and public policyThe Fund invests primarily in large-cap and mid-cap common stocks, and under normal circumstances, the Fund invests at least 80% of its Assets in the equity securities of U.S. companies meeting the adviser’s sustainability criteria. “Assets” means net assets, plus the amount of any borrowings for investment purposes. Because investing on the basis of sustainability/ESG criteria involves qualitative and subjective analysis, there can be no assurance that the methodology utilized by, or determinations made by, the adviser will align with the beliefs or values of a particular investor. Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for investments in certain securities. The Fund may use derivatives, primarily futures contracts, to gain or reduce exposure to its index or certain securities in its index, maintain liquidity, minimize transaction costs, or to more effectively gain targeted equity exposure from its cash positions. To the extent the Fund invests in index futures with exposure to securities in the index, it may have the effect of increasing the Fund’s exposure to a relatively small number of securities, making the Fund’s shares more sensitive to the economic results of those securities. In managing cash flows, the Fund buys futures contracts to invest incoming cash in the market or sells futures contracts in response to cash outflows, thereby gaining market exposure while maintaining a cash balance for liquidity. An issuer of a security will be deemed to be located in the U.S. if: (i) the principal trading market for the security is in the United States, (ii) the issuer is organized under the laws of the United States, or (iii) the issuer derives at least 50% of its revenues or profits from the United States or has at least 50% of its total assets situated in the U.S.Investment Process: The Fund has an actively managed strategy. In managing the Fund, the adviser employs a fundamental, bottom-up approach to stock selection, constructing portfolios based on company financials, data analysis and proprietary research. In choosing securities to purchase, the adviser evaluates and internally ranks companies to identify those companies that, in the adviser’s view, are sustainable leaders and have high quality, durable franchises, which the adviser believes are attractively valued. The adviser assesses sustainability based on fundamental analysis using a wide set of data inputs which may include proprietary research, information self-reported by companies, and third-party data. The adviser may vary the importance of particular ESG and investment characteristics by industry because, in the adviser’s judgment, certain characteristics are more relevant for certain industries. For example, an environmental characteristic, such as land use, may be more relevant for energy companies than for technology companies. In addition, the Fund seeks to avoid investing in companies that the adviser has determined, based on its exclusionary criteria, to be significantly involved in certain business activities or industries, including the production of tobacco, controversial weapons, traditional weapons, thermal coal, adult entertainment and gambling products and services, or to be violating certain norms-based criteria (for example, UN Global Compact violators). This exclusionary criteria relies on multiple data inputs, including information from third-party providers who identify an issuer’s participation in, or the revenue which they derive from, activities that are inconsistent with values- and norms-based screens. The adviser may modify the exclusionary criteria without notice to shareholders to, among other things, modify the data inputs, change third-party data providers, or add or remove certain business activities or industries from the screening process. The Fund has flexibility to focus in various industries or sectors based on the adviser’s analysis of market opportunities at a particular time. The Fund will sell a stock if the adviser determines that the issuer no longer meets the Fund’s investment criteria or if the adviser believes that more attractive opportunities are available.

Strategy Narrative [Text Block]	The Fund is a small cap equity portfolio which is normally managed as a core portfolio, but which has the ability to proactively invest more heavily in either growth or value securities depending on market conditions and the convictions of the adviser.The portfolio managers will consider various factors when making overall allocation decisions for the Fund, including the relative attractiveness of growth and value securities and the relative valuations and fundamentals of companies in the small cap growth and value universes. Based on these considerations, the size of the allocation of the Fund to either growth or value securities may range from 30 to 70 percent of the Fund. Under normal circumstances, the Fund invests at least 80% of its Assets in equity securities of small cap companies.Small cap companies are companies with market capitalizations equal to those within the universe of the Russell 2000® Index at the time of purchase. As of the reconstitution of the Russell 2000 Index on September 30, 2026, the market capitalizations of the companies in the index ranged from $5.62 million to $85.78 billion. In implementing its main strategies, the Fund invests primarily in common stocks and real estate investment trusts (REITs). “Assets” means net assets, plus the amount of borrowings for investment purposes. Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions. Investment Process: In managing the Fund, the Fund’s adviser seeks to outperform the Fund’s benchmark. The adviser employs a fundamental bottom-up investment process that combines research, valuation and stock selection to identify both growth and value securities. In selecting growth securities, the adviser seeks to invest in companies that have a history of above-average growth or that the adviser believes will achieve above-average growth in the future. The adviser believes that investing in high quality growth companies whose long-term growth rates are underappreciated by the market will lead to attractive returns. Growth companies purchased for the Fund include those with leading competitive positions, predictable and durable business models and management that can achieve sustained growth. In selecting value securities, the adviser seeks to invest in companies which have durable franchises and that the adviser believes to be attractively valued and to have the ability to grow intrinsic value per share. Companies with durable franchises generally have a sustainable competitive position relative to peers, high returns on capital, a diversified client or asset base and a strong brand.As part of its investment process, the adviser seeks to assess the impact of environmental, social and governance (ESG) factors on many issuers in the universe in which the Fund may invest. The adviser’s assessment is based on an analysis of key opportunities and risks across industries to seek to identify financially material issues with respect to the Fund’s investments in issuers and ascertain key issues that merit engagement with issuers. These assessments may not be conclusive, and securities of issuers that may be negatively impacted by such factors may be purchased and retained by the Fund while the Fund may divest or not invest in securities of issuers that may be positively impacted by such factors. The adviser may sell a security for several reasons. A security may be sold due to a change in the company’s fundamentals or if the adviser believes the security is no longer attractively valued. Investments may also be sold if the adviser identifies a security that it believes offers a better investment opportunity or to reallocate the Fund’s assets between growth and value securities.
Summary of Definition of Rule 35d-1 Term in Fund Name [Text Block]	The Fund is a small cap equity portfolio which is normally managed as a core portfolio, but which has the ability to proactively invest more heavily in either growth or value securities depending on market conditions and the convictions of the adviser.Small cap companies are companies with market capitalizations equal to those within the universe of the Russell 2000® Index at the time of purchase.
Summary of Selection Criteria for Rule 35d-1 Term in Fund Name [Text Block]	The portfolio managers will consider various factors when making overall allocation decisions for the Fund, including the relative attractiveness of growth and value securities and the relative valuations and fundamentals of companies in the small cap growth and value universes.In selecting growth securities, the adviser seeks to invest in companies that have a history of above-average growth or that the adviser believes will achieve above-average growth in the future. The adviser believes that investing in high quality growth companies whose long-term growth rates are underappreciated by the market will lead to attractive returns. Growth companies purchased for the Fund include those with leading competitive positions, predictable and durable business models and management that can achieve sustained growth. In selecting value securities, the adviser seeks to invest in companies which have durable franchises and that the adviser believes to be attractively valued and to have the ability to grow intrinsic value per share. Companies with durable franchises generally have a sustainable competitive position relative to peers, high returns on capital, a diversified client or asset base and a strong brand.
Rule 35d-1 Eighty Percent Investment Policy [Text Block]	Under normal circumstances, the Fund invests at least 80% of its Assets in equity securities of small cap companies.

Strategy Narrative [Text Block]	The Fund seeks to provide capital appreciation through participation in the broad equity markets while hedging overall market exposure relative to traditional long-only equity strategies.Under normal circumstances, the Fund invests at least 80% of its Assets in equity securities.Equity securities represent an ownership interest in the issuer. The Fund invests in equity securities, which primarily consist of common stocks of large cap U.S. companies. The Fund will also purchase and sell exchange traded put options and sell exchange traded call options, employing an options overlay known as a “Put/Spread Collar” strategy, designed to provide a continuous market hedge for the portfolio. The options will typically be based on the S&P 500 Index (the Index) or on exchange-traded funds (ETFs) that replicate the S&P 500 Index (S&P 500 ETFs). The combination of the diversified portfolio of equity securities, combined with the options overlay, is intended to provide the Fund with a significant portion of the returns associated with equity market investments, while exposing investors to less risk than traditional long-only equity strategies. “Assets” means net assets plus the amount of borrowings for investment purposes. Volatility is one way to measure risk and refers to the variability of the Fund’s or the market’s returns. The Fund seeks to provide a competitive risk-adjusted return over a full market cycle (defined as three to five years) relative to the S&P 500 Total Return Index with lower volatility than traditional long-only equity strategies. The Fund typically holds options for three month periods (each, an “hedge period”) for the purpose of seeking to provide more predictable returns in any market cycle during the applicable hedge period. The put option spread is generally maintained at a level intended to reduce the Fund's exposure to a market decline by offsetting losses resulting from a decrease in the market. As a result of writing call options to offset the costs associated with the put option spread, some upside may be foregone in certain market environments. The quarterly hedge periods are based on returns from the first business day of January through the last business day of March; the first business day of April through the last business day of June; the first business day of July through the last business day of September; and the first business day of October through the last business day of December. The Fund’s investments in equity securities will be primarily in common stocks of U.S. companies with market capitalizations similar to those within the universe of the Index. As of the reconstitution of the Index on September 30, 2026, the market capitalizations of the companies in the Index ranged from $6.20 billion to $5.50 trillion. The Fund may also invest in equity securities of U.S. mid cap companies. The adviser’s process focuses on stock selection and tends to maintain sector weightings comparable to those of the broad U.S. large cap market. Within each sector, however, the Fund modestly overweights equity securities that it considers undervalued or fairly valued while modestly underweighting or not holding equity securities that appear overvalued. The Fund constructs a Put/Spread Collar by buying a put option on the Index at a higher strike price and writing (or selling) a put option on the Index at a relatively lower strike price, resulting in what is known as a put option spread, while simultaneously selling an Index call option. The Fund may need to construct additional Put/Spread Collars if the size of the Fund increases, either through purchases or appreciation. The Fund’s options overlay strategy is intended to provide the Fund with downside protection, while foregoing some upside potential. A put option spread seeks to protect the Fund against a decline in price, but only to the extent of the difference between the strike prices of the put option purchased and the put option sold. Entering into put option spreads is typically less expensive than a strategy of only purchasing put options and may benefit the Fund in a flat to upwardly moving market by reducing the cost of the downside protection; the downside protection of the put option spread, however, is limited as compared to just owning a put option. The premiums received from writing index call options are intended to provide income which substantially offsets the cost of the put option spread, but writing the options also reduces the Fund’s ability to profit from increases in the value of its equity portfolio because in rising markets the call option will be exercised once the market price rises to the option’s strike price. While the Fund typically constructs the Put/Spread Collar utilizing index options, it may also construct the Put/Spread Collar utilizing options on S&P 500 ETFs. The Fund’s investment strategies may not always provide greater market protection than other equity investments, particularly in rising equity markets when the Fund is expected to underperform traditional long-only equity strategies. In addition, as a result of selling call options to offset the costs associated with the options overlay strategy, some upside may be foregone in certain market environments. While the Fund will not generally invest directly in ETFs, there may be times when it will purchase shares or receive shares of S&P 500 ETFs in order to settle its options positions. The adviser will not normally maintain such positions for an extended period. Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for investments in certain securities. In addition to the use of the Put/Spread Collar strategy described above, the Fund may use derivatives, primarily futures contracts, to gain exposure to indexes or certain securities within indexes, to more effectively gain targeted equity exposure from its cash positions, and to hedge the Fund’s portfolio if it is unable to purchase or write the necessary options for its overlay strategy and efficient management of cash flows. To the extent the Fund invests in index futures with exposure to securities in the index, it may have the effect of increasing the Fund’s exposure to a relatively small number of securities, making the Fund’s shares more sensitive to the economic results of those securities. The Fund is also permitted to use other derivatives such as futures, options (including options on futures) and swaps in order to hedge various investments and for risk management. Under certain market conditions, the Fund's use of other derivatives for cash management or other investment management purposes could be significant. Investment Process —Equity Portfolio: With respect to the investment of the equity portfolio, the adviser employs a three-step process that combines research, valuation and stock selection. The adviser takes an in-depth look at company prospects over a period as long as five years, which is designed to provide insight into a company’s real growth potential. The research findings allow the adviser to rank the companies in each sector group according to their relative value. As part of its investment process, the adviser seeks to assess the impact of environmental, social and governance (ESG) factors on many issuers in the universe in which the Fund may invest. The adviser’s assessment is based on an analysis of key opportunities and risks across industries to seek to identify financially material issues with respect to the Fund’s investments in issuers and ascertain key issues that merit engagement with issuers. These assessments may not be conclusive, and securities of issuers that may be negatively impacted by such factors may be purchased and retained by the Fund while the Fund may divest or not invest in securities of issuers that may be positively impacted by such factors. On behalf of the Fund, the adviser then buys and sells equity securities, using the research and valuation rankings as a basis. In general, the adviser buys equity securities that are identified as attractive and considers selling them when they appear less attractive based on the Fund’s process. Along with attractive valuation, the adviser often considers a number of other criteria, including: ●catalysts, such as improving company fundamentals, that could trigger a rise in a stock’s price ●impact on the overall risk of the portfolio ●high perceived potential reward compared to perceived potential risk ●possible temporary mispricings caused by apparent market overreactions. Investment Process — Options Overlay Strategy: To implement the Put/Spread Collar strategy, the adviser utilizes exchange traded equity options based either on the Index or on S&P 500 ETFs. The Put/Spread Collar is constructed by buying a put option at a higher strike price while writing a put option at a relatively lower strike price and simultaneously selling a call option that substantially offsets the cost of the put option spread. The Put/Spread Collar strategy is an actively managed process and is designed to provide a continuous market hedge for the portfolio. The put option spread is generally maintained at a level intended to protect the Fund from a decrease in the market of 5% to 20%, with potential upside generally capped at 3.5-5.5%. The upside cap could be more or less, depending on market conditions. The options are systematically reset on at least a quarterly basis to better capitalize on current market conditions and opportunities while seeking to provide predictable returns in all market cycles.

Strategy Narrative [Text Block]	Under normal circumstances, at least 80% of the value of the Fund’s Assets, which are expected to include both long and short positions, will consist of different U.S. securities, selected from a universe of publicly traded large capitalization securities with characteristics similar to those comprising the S&P 500 Index. The Fund takes long and short positions mainly in equity securities and derivatives on equity securities. “Assets” means net assets, plus the amount of borrowings for investment purposes. As of the reconstitution of the S&P 500 Index on September 30, 2026, the market capitalizations of the companies in the index ranged from $6.20 billion to $5.50 trillion.“Plus” in the Fund’s name refers to the additional return the Fund endeavors to add both relative to the S&P 500 Index as well as relative to traditional strategies which do not have the ability to sell stock short. Selling stock short allows the Fund to more fully exploit insights in stocks that the Fund’s adviser expects to underperform, as well as enabling the Fund to establish additional long positions while keeping the Fund’s net exposure to the market at a level similar to a traditional “long-only” strategy. Short sales involve the sale of a security which the fund does not own in expectation of purchasing the same security at a later date at a lower price. To make delivery to the buyer, the Fund must borrow the security, and the fund is obligated to return the security to the lender, which is accomplished by a later purchase of the security by the Fund. The Fund may also periodically short index futures in order to hedge its market exposure in instances when it is not preferable to enter into short positions on particular securities in the amount desired. The Fund intends to maintain an approximate net 100% long exposure to the equity market (long market value minus short market value). However the long and short positions held by the Fund will vary in size as market opportunities change. The Fund’s long positions and their equivalents will range between 90% and 150% of the value of the Fund’s net assets. The Fund’s short positions will range between 0% and 50% of the value of the Fund’s net assets. Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for investments in certain securities. The Fund currently intends to use swaps (including equity swaps) to establish its short equity positions, if any. The Fund may also use swaps to establish long equity positions, without owning or taking physical custody of securities. The payments received by the Fund under such swaps may be adjusted for transaction costs, interest payments, the amount of dividends paid on the investment or instrument or other factors. The Fund may also use futures contracts to gain exposure to its index or certain securities in its index, or to more effectively gain targeted equity exposure from its cash positions. To the extent the Fund invests in index futures with exposure to securities in the index, it may have the effect of increasing the Fund’s exposure to a relatively small number of securities, making the Fund’s shares more sensitive to the economic results of those securities. An issuer of a security will be deemed to be located in the United States if: (i) the principal trading market for the security is in the United States, (ii) the issuer is organized under the laws of the United States, or (iii) the issuer derives at least 50% of its revenues or profits from the United States or has at least 50% of its total assets situated in the United States.Investment Process: In managing the Fund, the adviser employs a three-step process that combines research, valuation and stock selection.

Strategy Narrative [Text Block]	Under normal circumstances, the Fund will invest at least 80% of its Assets in common stocks issued by U.S. value companies.Value companies are those that the adviser believes are undervalued or attractively valued, based on one or more of the following factors: how the stock price compares to the company’s sales, earnings, and assets, as well as the overall value of the company compared to its sales and the capital invested in it. “Assets” means net assets, plus the amount of borrowings for investment purposes. The Fund’s adviser applies an active equity management style focused on identifying attractively valued securities given their growth potential over a long-term time horizon.

Sector by sector, the Fund’s weightings are similar to those of the Russell 2000® Index. The Fund can moderately underweight or overweight sectors when it believes it will benefit performance. The Fund pursues returns that exceed those of the Russell 2000® Index while seeking to limit its volatility relative to this index. In implementing its main strategies, the Fund’s investments are primarily in common stocks and real estate investment trusts (REITs).Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. The Fund may use futures contracts to gain or reduce exposure to its index, maintain liquidity and minimize transaction costs. In managing cash flows, the Fund buys futures contracts to invest incoming cash in the market or sells futures contracts in response to cash outflows, thereby gaining market exposure to the index while maintaining a cash balance for liquidity. An issuer of a security will be deemed to be located in the United States if: (i) the principal trading market for the security is in the United States, (ii) the issuer is organized under the laws of the United States, or (iii) the issuer derives at least 50% of its revenues or profits from the United States or has at least 50% of its total assets situated in the United States.Investment Process: In managing the Fund, the adviser employs a process that ranks stocks based on its proprietary stock ranking system. The rankings are then reviewed and adjusted utilizing fundamental research conducted by the investment team to enhance accuracy and consistency. The adjusted rankings are used to place stocks into portfolios. As part of its investment process, the adviser seeks to assess the impact of environmental, social and governance (ESG) factors on many issuers in the universe in which the Fund may invest. The adviser’s assessment is based on an analysis of key opportunities and risks across industries to seek to identify financially material issues with respect to the Fund’s investments in issuers and ascertain key issues that merit engagement with issuers. These assessments may not be conclusive, and securities of issuers that may be negatively impacted by such factors may be purchased and retained by the Fund while the Fund may divest or not invest in securities of issuers that may be positively impacted by such factors. In general, stocks are purchased when they are among the top ranked within their sector. Stocks become candidates for sale when their ranking falls, when they appear unattractive or when the company is no longer a small cap company. The Fund may continue to hold the securities if it believes further substantial growth is possible. Risk factor exposures are managed through portfolio construction. Portfolio constraints control for sector weights, position sizes and/or style characteristics of the Fund.

Strategy Narrative [Text Block]	The Fund is a small cap equity portfolio which is normally managed as a core portfolio, but which has the ability to proactively invest more heavily in either growth or value securities depending on market conditions and the convictions of the adviser.The portfolio managers will consider various factors when making overall allocation decisions for the Fund, including the relative attractiveness of growth and value securities and the relative valuations and fundamentals of companies in the small cap growth and value universes. Based on these considerations, the size of the allocation of the Fund to either growth or value securities may range from 30 to 70 percent of the Fund.

Investment Process: In managing the Fund, the Fund’s adviser seeks to outperform the Fund’s benchmark. The adviser employs a fundamental bottom-up investment process that combines research, valuation and stock selection to identify both growth and value securities. In selecting growth securities, the adviser seeks to invest in companies that have a history of above-average growth or that the adviser believes will achieve above-average growth in the future. The adviser believes that investing in high quality growth companies whose long-term growth rates are underappreciated by the market will lead to attractive returns. Growth companies purchased for the Fund include those with leading competitive positions, predictable and durable business models and management that can achieve sustained growth. In selecting value securities, the adviser seeks to invest in companies which have durable franchises and that the adviser believes to be attractively valued and to have the ability to grow intrinsic value per share.

Investment Strategy

Jun. 30, 2026

What are the Fund’s main investment strategies?

Drawing on a variety of analytical tools, the Fund’s adviser typically seeks to invest the Fund’s assets among various types of asset classes which include the following allocations: ●35%–80% equity securities ●15%–65% fixed income securities ●0-10% alternative securities ●0%–10% convertible securitiesThe Fund invests in separate underlying strategies by investing directly in individual securities, in other mutual funds and exchange traded funds (ETFs) within the same group of investment companies (J.P. Morgan Funds), and for the limited purposes described below, in passive ETFs that are managed by unaffiliated investment advisers (unaffiliated passive ETFs). The Fund may also invest in unaffiliated closed-end registered investment companies and other pooled investment vehicles (collectively with J.P. Morgan Funds and unaffiliated ETFs, underlying funds), across asset classes, including: U.S. equity and developed international equity across market capitalizations, emerging markets equity, domestic and foreign fixed income, high yield fixed income, emerging markets debt, and real estate investment trusts (REITs). A passive ETF is a registered investment company that seeks to track the performance of a particular market index. These indices include not only broad-based market indices but more specific indices as well, including those relating to particular sectors, markets, factors, regions or industries. The adviser may periodically increase or decrease the Fund’s actual asset allocations according to the relative attractiveness of each asset class. Within its equity allocations, the Fund invests primarily in the common stock of U.S. and foreign companies, REITs, and underlying funds primarily invest in such securities. Within its fixed income allocations, the Fund invests primarily in corporate bonds, asset-backed, mortgage- related and mortgage-backed securities, U.S. and foreign government securities, loan assignments and participations (Loans) and commitments to purchase loan assignments, emerging market debt and underlying funds that primarily invest in such securities.The Fund may invest in fixed income securities of any credit quality but may only invest up to 25% of its total assets in certain below investment grade securities (also known as high yield securities or junk bonds). This limit on below investment grade securities will include all investments held either directly by the Fund or in underlying funds held by the Fund which invest primarily in below investment grade securities (as disclosed in the underlying fund’s prospectus). In addition, the Fund may invest in underlying funds that may invest in fixed income securities of various credit qualities, including at times below investment grade securities, in order to expose the Fund to certain asset classes, such as emerging market debt. The remainder of the fixed income allocation will be invested directly in securities that, at the time of purchase are rated investment grade by a nationally recognized statistical rating organization or in securities that are unrated but are deemed by the Fund’s adviser to be of comparable quality. The Fund may invest in fixed income securities of any average weighted maturity or duration. The Fund may invest up to 30% of its total assets in shares of equity or fixed income underlying funds in order to expose the Fund to certain asset classes. To the extent the Fund invests in underlying funds, the adviser expects to select J.P. Morgan Funds without considering or canvassing the universe of unaffiliated underlying funds available, even though there may (or may not) be one or more unaffiliated underlying funds that investors might regard as more attractive for the Fund or that have superior returns. For both actively-managed underlying funds and ETFs, the adviser limits its selection to J.P. Morgan Funds. For passive ETFs, the adviser expects to invest in affiliated ETFs that are J.P. Morgan Funds (J.P. Morgan ETFs), unless the adviser determines the investment is not available. To the extent the adviser determines in its sole discretion that an investment in a passive J.P. Morgan ETF is not available, only then will the adviser consider an unaffiliated passive ETF. In addition, the Fund may seek to gain passive exposure to one or more markets by investing directly in the securities underlying a particular index. The Fund may also invest up to 10% of its assets in convertible securities. Additionally, the Fund may also invest up to 10% of its securities in alternative securities. The Fund's alternative securities investments may include individual securities, investments in underlying funds, and other pooled investment vehicles, including vehicles that hold or provide exposure to commodities, currencies or commodity futures. In addition to investments in underlying funds and direct investments in securities, the Fund may use derivatives, which are instruments that have a value based on another instrument, exchange rate or index, as substitutes for securities in which the Fund can invest. The Fund may use futures contracts, options, and swaps to more effectively gain targeted equity and fixed income exposure from its cash positions, to hedge investments, for risk management and to attempt to increase the Fund’s returns. The Fund may use futures contracts, options (including options on interest rate futures contracts and interest rate swaps), swaps, and credit default swaps to help manage duration, sector and yield curve exposure and credit and spread volatility. The Fund may utilize exchange traded futures contracts for cash management and to gain exposure to equities pending investment in individual securities. The Fund may invest in securities denominated in any currency. The Fund may also utilize foreign currency derivatives such as forward currency transactions to hedge exposure to non-dollar investments back to the U.S. dollar, as well as to gain exposure to certain currencies. Although the Fund will generally maintain its assets within the allocations above, the Fund may hold cash or cash equivalents for various purposes, including in connection with segregation for derivatives transactions, as collateral for derivatives transactions or for temporary defensive purposes. The adviser establishes the strategic and tactical allocation for the Fund and makes the day-to-day decisions concerning strategies and overall construction of the Fund. As attractive investments arise across asset classes and strategies, the adviser attempts to capture these opportunities by allocating the Fund’s assets among strategies and asset classes within pre-defined ranges. Investment decisions within strategies and asset classes are implemented either by the portfolio managers of the Fund’s underlying strategies who select individual securities for the Fund or with the Fund’s purchase of underlying funds. The frequency with which the Fund buys and sells underlying investments will vary from year to year, depending on, but not limited to: market conditions, performance of the underlying investments, and changes in the adviser’s investment views.
