Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate

higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual Fund operating expenses or in the Example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 37.84% of the average value of its portfolio.

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of the period. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. The Example reflects adjustments made to the Fund's operating expenses due to the fee waivers and/or expense reimbursements by management for the 1 Year numbers only. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

Under normal market conditions, the Fund invests at least 80% of its net assets in U.S. mid cap companies. Mid capitalization companies are companies with market capitalizations (the total market value of a company’s outstanding stock) not exceeding either: 1) the highest market capitalization in the Russell Midcap® Index; or 2) the 12-month average of the highest market capitalization in the Russell Midcap® Index, whichever is greater, at the time of purchase. As of December 31, 2024, the highest market capitalization in the Russell Midcap® Index was $172.23 billion and the 12-month average of the highest market capitalization in the Russell Midcap® Index was $96.29 billion.

Under normal market conditions, the Fund invests primarily in equity securities (including securities convertible into, or that the investment manager expects to be exchanged for, common or preferred stock) of U.S. companies that the investment manager believes are available at market prices less than their value based on certain recognized or objective criteria (fundamental value). Following this value-oriented strategy, the Fund invests primarily in undervalued securities (securities trading at a discount to fundamental value). The equity securities in which the Fund invests are primarily common stock. The Fund may also invest in real estate investment trusts (REITs).

The Fund may invest up to 20% of its net assets in foreign securities.

The Fund may, from time to time, seek to hedge (protect) against currency risks, using certain derivative instruments including, currency and cross currency forwards and currency futures contracts.

The Fund, from time to time, may have significant positions in particular sectors, such as financial services companies (including banks, insurance companies and diversified financial services), healthcare, industrials, technology, consumer discretionary, utilities and real estate.

Portfolio Selection

The investment manager employs a research driven, fundamental value strategy for the Fund. Investments are generally selected based on the investment manager's own analysis of the security's fundamental value, including for equity securities, an analysis of cash flow potential, long-term earnings, multiples of earnings and book value. The investment manager examines each investment

separately and there are no set criteria as to specific value parameters, earnings or industry type. Environmental, social and governance (ESG) related assessments of companies may also be considered. The investment manager does not assess every investment for ESG factors and, when it does, not every ESG factor may be identified or evaluated.

Principal Risks

You could lose money by investing in the Fund. Mutual fund shares are not deposits or obligations of, or guaranteed or endorsed by, any bank, and are not insured by the Federal Deposit Insurance Corporation, the Federal Reserve Board, or any other agency of the U.S. government.

FRANKLIN MUTUAL U.S. MID CAP VALUE FUND | Market  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Market: The market values of securities or other investments owned by the Fund will go up or down, sometimes rapidly or unpredictably. The market value of a security or other investment may be reduced by market activity or other results of supply and demand unrelated to the issuer. This is a basic risk associated with all investments. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise.

Stock prices tend to go up and down more dramatically than those of debt securities. A slower-growth or recessionary economic environment could have an adverse effect on the prices of the various stocks held by the Fund.

FRANKLIN MUTUAL U.S. MID CAP VALUE FUND | Value Style Investing  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Value Style Investing: A value stock may not increase in price as anticipated by the investment manager if other investors fail to recognize the company's value and bid up the price, the markets favor faster-growing companies, or the factors that the investment manager believes will increase the price of the security do not occur or do not have the anticipated effect.

Cyclical stocks, which typically follow the cycles of an economy through expansion, peak, recession, and recovery, tend to increase in value more quickly during periods of anticipated economic upturns than non-cyclical stocks, but they also tend to lose value more quickly in periods of anticipated economic downturns. These companies may have relatively weak balance sheets and, during economic downturns, they may have insufficient cash flow to pay their debt obligations and difficulty finding additional financing needed for their operations.

FRANKLIN MUTUAL U.S. MID CAP VALUE FUND | Small and Mid Capitalization Companies  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Small and Mid Capitalization Companies: Securities issued by small and mid capitalization companies may be more volatile in price than those of larger companies and may involve substantial risks. Such risks may include greater sensitivity to economic conditions, less certain growth prospects, lack of depth of management and funds for growth and development, and limited or less developed product lines and markets. In addition, small and mid capitalization companies may be particularly affected by interest rate increases, as they may find it more difficult to borrow money to continue or expand operations, or may have difficulty in

repaying any loans. The markets for securities issued by small and mid capitalization companies also tend to be less liquid than the markets for securities issued by larger companies.

FRANKLIN MUTUAL U.S. MID CAP VALUE FUND | Focus  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Focus: To the extent that the Fund focuses on particular countries, regions, industries, sectors or types of investments from time to time, the Fund may be subject to greater risks of adverse developments in such areas of focus than a fund that invests in a wider variety of countries, regions, industries, sectors or investments.

FRANKLIN MUTUAL U.S. MID CAP VALUE FUND | Financial services companies  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Financial services companies: Financial services companies are subject to extensive government regulation that may affect their profitability in many ways, including by limiting the amount and types of loans and other commitments they can make, and the interest rates and fees they can charge. A financial services company's profitability, and therefore its stock prices, is especially sensitive to interest rate changes as well as the ability of borrowers to repay their loans. Changing regulations, continuing consolidations, and development of new products and structures all are likely to have a significant impact on financial services companies.

FRANKLIN MUTUAL U.S. MID CAP VALUE FUND | Healthcare companies  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Healthcare companies: The activities of healthcare companies may be funded or subsidized by federal and state governments. If government funding and subsidies are reduced or discontinued, the profitability of these companies could be adversely affected. Healthcare companies may also be affected by government policies on healthcare reimbursements, regulatory approval for new drugs and medical products, and similar matters. They are also subject to legislative risk, i.e., the risks associated with the reform of the healthcare system through legislation.

FRANKLIN MUTUAL U.S. MID CAP VALUE FUND | Industrials companies  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Industrials companies: The stock prices of companies in the industrials sector are affected by supply and demand both for their specific product or service and for industrials sector products in general. Companies in the industrials sector may be adversely affected by changes in government regulation, world events and economic conditions. In addition, these companies are at risk for environmental damage and product liability claims. Companies in this sector could be adversely affected by commodity price volatility, changes in exchange rates, imposition of export or import controls, increased competition, depletion of resources, technological developments and labor relations.

FRANKLIN MUTUAL U.S. MID CAP VALUE FUND | Technology companies  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Technology companies: Companies in the technology sector have historically been volatile due to the rapid pace of product change and development within the sector. For example, their products and services may not prove commercially successful or may become obsolete quickly. In addition, delays in or cancellation of the release of anticipated products or services may also affect the price of a technology company’s stock. Technology companies are subject to significant competitive pressures, such as new market entrants, aggressive pricing and tight profit

margins. The activities of these companies may also be adversely affected by changes in government regulations, worldwide technological developments or investor perception of a company and/or its products or services. The stock prices of companies operating within this sector may be subject to abrupt or erratic movements.

FRANKLIN MUTUAL U.S. MID CAP VALUE FUND | Consumer discretionary companies  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Consumer discretionary companies: Companies in the consumer discretionary sector could be affected by, among other things, overall economic conditions, interest rates, consumer confidence, and disposable income.

FRANKLIN MUTUAL U.S. MID CAP VALUE FUND | Utilities companies  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Utilities companies: Utility company equity securities, historically have been sensitive to interest rate movements: when interest rates have risen, the stock prices of these companies have tended to fall. In some states, utility companies and their rates are regulated; other states have moved to deregulate such companies thereby causing non-regulated companies’ returns to generally be more volatile and more sensitive to changes in revenue and earnings. Certain utilities companies face risks associated with the operation of nuclear facilities for electric generation, including, among other considerations, litigation, the problems associated with the use of radioactive materials; the effects of natural or man-made disasters; and the potential for government decommissioning. In general, all utility companies may face additional regulation and litigation regarding their power plant operations; increased costs from new or greater regulation of these operations; the need to purchase expensive emissions control equipment or new operations due to regulations; and the availability and cost of fuel, all of which may lower their earnings.

FRANKLIN MUTUAL U.S. MID CAP VALUE FUND | Real estate companies  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Real estate companies: Real estate values rise and fall in response to a variety of factors, including: local, regional, national and global economic conditions; interest rates; tax and insurance considerations; changes in zoning and other property-related laws; environmental regulations or hazards; overbuilding; increases in property taxes and operating expenses; or value decline in a neighborhood. When economic growth is slow, demand for property decreases and prices may decline.

FRANKLIN MUTUAL U.S. MID CAP VALUE FUND | REITs  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

REITs: A REIT’s performance depends on the types, values and locations of the properties and companies it owns and how well those properties and companies are managed. A decline in rental income may occur because of extended vacancies, increased competition from other properties, tenants’ failure to pay rent or poor management. Because a REIT may be invested in a limited number of projects or in a particular market segment, it may be more susceptible to adverse developments affecting a single project or market segment than more broadly diversified investments. Loss of status as a qualified REIT under the U.S. federal tax laws could adversely affect the value of a particular REIT or the market for REITs as a whole. These risks may also apply to securities of REIT-like entities domiciled outside the U.S.

FRANKLIN MUTUAL U.S. MID CAP VALUE FUND | Foreign Securities (non-U.S.)  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Foreign Securities (non-U.S.): Investing in foreign securities typically involves more risks than investing in U.S. securities, and includes risks associated with: (i) internal and external political and economic developments – e.g., the political, economic and social policies and structures of some foreign countries may be less stable and more volatile than those in the U.S. or some foreign countries may be subject to trading restrictions or economic sanctions; diplomatic and political developments could affect the economies, industries, and securities and currency markets of the countries in which the Fund is invested, which can include rapid and adverse political changes; social instability; regional conflicts; sanctions imposed by the United States, other nations or other governmental entities, including supranational entities; terrorism; and war; (ii) trading practices – e.g., government supervision and regulation of foreign securities and currency markets, trading systems and brokers may be less than in the U.S.; (iii) availability of information – e.g., foreign issuers may not be subject to the same disclosure, accounting and financial reporting standards and practices as U.S. issuers; (iv) limited markets – e.g., the securities of certain foreign issuers may be less liquid (harder to sell) and more volatile; and (v) currency exchange rate fluctuations and policies – e.g., fluctuations may negatively affect investments denominated in foreign currencies and any income received or expenses paid by the Fund in that foreign currency.

FRANKLIN MUTUAL U.S. MID CAP VALUE FUND | Derivative Instruments  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Derivative Instruments: The performance of derivative instruments depends largely on the performance of an underlying currency, security, interest rate or index, and such derivatives often have risks similar to the underlying instrument, in addition to other risks. Derivatives involve costs and can create economic leverage in the Fund’s portfolio which may result in significant volatility and cause the Fund to participate in losses (as well as gains) in an amount that significantly exceeds the Fund’s initial investment. Other risks include illiquidity, mispricing or improper valuation of the derivative, and imperfect correlation between the value of the derivative and the underlying instrument so that the Fund may not realize the intended benefits. Their successful use will usually depend on the investment manager’s ability to accurately forecast movements in the market relating to the underlying instrument. Should a market or markets, or prices of particular classes of investments move in an unexpected manner, especially in unusual or extreme market conditions, the Fund may not realize the anticipated benefits of the transaction, and it may realize losses, which could be significant. If the investment manager is not successful in using such derivative instruments, the Fund’s performance may be worse than if the investment manager did not use such derivatives at all. When a derivative is used for hedging, the change in value of the derivative may also not correlate specifically with the currency, security, interest rate, index or other risk being hedged. Derivatives also may present the risk that the other party to the transaction will fail to perform. There is also the risk, especially under extreme market conditions, that a derivative, which usually would operate as a hedge, provides no hedging benefits at all.

FRANKLIN MUTUAL U.S. MID CAP VALUE FUND | Convertible Securities  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Convertible Securities: Convertible securities are subject to the risks of stocks when the underlying stock price is high relative to the conversion price (because more of the security's value resides in the conversion feature) and debt securities when the underlying stock price is low relative to the conversion price (because the conversion feature is less valuable). The value of convertible securities may rise and fall with the market value of the underlying stock or, like a debt security, vary with changes in interest rates and the credit quality of the issuer. A convertible security is not as sensitive to interest rate changes as a similar non-convertible debt security, and generally has less potential for gain or loss than the underlying stock.

FRANKLIN MUTUAL U.S. MID CAP VALUE FUND | Management  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Management: The Fund is subject to management risk because it is an actively managed investment portfolio. The Fund's investment manager applies investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these decisions will produce the desired results.

FRANKLIN MUTUAL U.S. MID CAP VALUE FUND | ESG Considerations  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

ESG Considerations: ESG considerations are one of a number of factors that the investment manager examines when considering investments for the Fund’s portfolio. In light of this, the issuers in which the Fund invests may not be considered ESG-focused companies. In addition, ESG considerations assessed as part of the Fund’s investment process may vary across types of eligible investments and issuers. The investment manager does not assess every investment for ESG factors and, when it does, not every ESG factor may be identified or evaluated. The investment manager’s assessment of an issuer may differ from that of investors, third-party service providers, such as ratings providers, and other funds. As a result, securities selected by the investment manager may not reflect the beliefs and values of any particular investor. The investment manager also may be dependent on the availability of timely, complete and accurate ESG data being reported by issuers and/or third-party research providers to evaluate ESG factors. ESG factors are often not uniformly measured or defined, which could impact the investment manager’s ability to assess an issuer. While the investment manager views ESG considerations as having the potential to contribute to the Fund’s long-term performance, there is no guarantee that such results will be achieved.

FRANKLIN MUTUAL U.S. MID CAP VALUE FUND | Cybersecurity  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Cybersecurity: Cybersecurity incidents, both intentional and unintentional, may allow an unauthorized party to gain access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, cause the Fund, the investment manager, and/or their service providers (including, but not limited to, Fund accountants, custodians, sub-custodians, transfer agents and financial intermediaries) to suffer data breaches, data corruption or loss of operational functionality or prevent Fund investors from purchasing, redeeming or exchanging shares or receiving distributions. The investment manager has limited ability to prevent or mitigate cybersecurity incidents affecting third party service

providers, and such third party service providers may have limited indemnification obligations to the Fund or the investment manager. Cybersecurity incidents may result in financial losses to the Fund and its shareholders, and substantial costs may be incurred in an effort to prevent or mitigate future cybersecurity incidents. Issuers of securities in which the Fund invests are also subject to cybersecurity risks, and the value of these securities could decline if the issuers experience cybersecurity incidents.

Because technology is frequently changing, new ways to carry out cyber attacks are always developing. Therefore, there is a chance that some risks have not been identified or prepared for, or that an attack may not be detected, which puts limitations on the Fund's ability to plan for or respond to a cyber attack. Like other funds and business enterprises, the Fund, the investment manager, and their service providers are subject to the risk of cyber incidents occurring from time to time.

There is a 1% contingent deferred sales charge that applies to investments of $1 Million or more (see "Investments of $1 Million or More" under "Choosing a Share Class") and purchases by certain retirement plans without an initial sales charge on shares sold within 18 months of purchase.

[2] Total annual Fund operating expenses differ from the ratio of expenses to average net assets shown in the Financial Highlights, which reflect the operating expenses of the Fund and do not include acquired fund fees and expenses.
[3] The investment manager has agreed to reduce its fees to reflect reduced services resulting from the Fund’s investments in Franklin Templeton affiliated funds. In addition, the transfer agency fees on Class R6 shares of the Fund have been capped so that transfer agency fees for that class do not exceed 0.03%. These arrangements are expected to continue until February 28, 2026. During the terms, the fee waiver and expense reimbursement agreements may not be terminated or amended without approval of the board of trustees except to add series or classes, to reflect the extension of termination dates or to lower the waiver and expense limitation (which would result in lower fees for shareholders).
