Commitments and Contingencies	Commitments and Contingencies Legal Proceedings India Credit Fund Closure Matters. Effective April 24, 2020, Franklin Templeton Trustee Services Private Limited (“FTTS”), a subsidiary of Franklin, announced its decision to wind up six fixed income mutual fund schemes of the Franklin Templeton Mutual Fund in India (referred to herein as the “Funds”), closing the Funds to redemptions. At the time, the Funds had collective AUM of INR 25,648.3 crore (approximately $3.4 billion). In connection with the wind-up decision, FTTS sought to convene unitholder meetings for the Funds to approve the appointment of a liquidator, and the asset management company to the Funds, Franklin Templeton Asset Management (India) Private Limited (“FTAMI”), ceased earning investment management fees on the Funds. In May and June 2020, certain Fund unitholders and others challenged the wind-up decision by filing legal petitions in India against a number of respondents, including Franklin, its subsidiaries FTTS, FTAMI, and Templeton International, Inc., as sponsor of the Franklin Templeton Mutual Fund, and related individuals (collectively, the “Company Respondents”), the Securities and Exchange Board of India (“SEBI”), and other governmental entities. The petitioners alleged that the Company Respondents violated various SEBI regulations, mismanaged the Funds, misrepresented or omitted certain information relating to the Funds, and/or engaged in other alleged misconduct. The petitioners requested a wide range of relief, including, among other items, an order quashing the winding up notices and blocking the unitholder votes, initiating investigations into the Company Respondents, and allowing the unitholder petitioners to redeem their investments with interest. An interim injunction order staying the operation and implementation of the unitholder voting process was issued and the petitions were transferred to the High Court of Karnataka for further consolidated proceedings. The court upheld the decision taken by FTTS to wind up the Funds while finding that unitholder approval was required to implement the decision. Cross appeals from the judgment were then filed in the Supreme Court of India. In the interim, FTTS proceeded to obtain approval from the majority of the voting unitholders for winding up the six Funds and in February 2021, the Supreme Court confirmed the results and appointed a third-party asset manager to serve as the liquidator and begin cash distributions to unitholders. The additional issues on appeal remain pending. By September 2023, all performing securities across the Funds were liquidated and an aggregate of INR 27,508.1 crore (approximately $3.3 billion) was distributed to Fund unitholders, exceeding the aggregate value of the Funds’ AUM at the date of the wind-up announcement, reported above. Separately, following the completion of a forensic audit/inspection, in late November and early December 2020, SEBI initiated regulatory proceedings by issuing show cause notices against FTAMI, FTTS and certain FTAMI employees (including in their officer or director capacities), alleging certain deficiencies and areas of non-compliance in the management of the Funds. In June 2021, SEBI issued orders against FTAMI, FTTS, and the FTAMI employee respondents, finding violations of certain regulatory provisions, including with respect to similarity in investment strategies among the Funds, calculation of duration and valuation of portfolio securities, deficiencies in documentation relating to investment diligence and investment terms, and portfolio risk management. SEBI’s orders include, as applicable, aggregate monetary penalties of INR 20.0 crore (approximately $2.4 million); disgorgement of investment management and advisory fees, together with interest through the date of SEBI’s order, totaling INR 512.5 crore (approximately $61.7 million), with continuing accrual of 12% interest until paid; and a prohibition on FTAMI from launching new fixed income funds in India for a two-year period. The respondents filed appeals, as well as applications to stay enforcement of SEBI’s orders pending resolution of the appeals, with the Securities Appellate Tribunal (the “SAT”) in India, which stay applications were granted in June and July 2021, subject to respondents’ deposit in escrow of a portion of the ordered penalties for an aggregate deposit made of INR 257.5 crore (approximately $34.7 million). The SAT appeals remain pending and in the interim, SEBI has approved FTAMI’s launch of certain new fixed income funds. The Company has also responded to related inquiries and investigations commenced by certain governmental agencies in India that remain pending, including a “first information report” (the preliminary step in an investigation) registered by the Economic Offences Wing of the Chennai police department in or around September 2020 against certain of the Company Respondents in connection with a complaint by certain Fund unitholders, as well as a related investigation by India’s Enforcement Directorate commenced in or around April 2021. The Company strongly believes that the decision taken by FTTS to wind up the Funds was in the best interests of unitholders and allowed for the orderly liquidation and distribution of Fund assets as described above. The Company further believes that it has meritorious defenses to the outstanding claims in the pending proceedings and intends to continue vigorously defending against the claims. The Company cannot at this time predict the eventual outcome of the matters described above or reasonably estimate the possible loss or range of loss that may arise from any final outcome of such matters, including due to the complexities and uncertainty involved in the appeals and the various questions of law and fact at issue. Western Asset Management Investigations and Litigation. As previously disclosed, the Company launched an internal investigation into certain trade allocations of treasury derivatives in select WAM managed accounts. WAM received notification of parallel investigations by the SEC and the U.S. Department of Justice (“DOJ”). WAM also received notice of an investigation into these trading activities by the CFTC. On June 30, 2025, the CFTC informed WAM that it closed its investigation. The SEC and DOJ investigations remain ongoing. The Company and WAM have fully cooperated, and will continue to fully cooperate with the SEC and DOJ investigations. Ken Leech, the former co-Chief Investment Officer of WAM, received a “Wells Notice” from the staff of the SEC in August 2024, and was placed on administrative leave at that time. Mr. Leech retired and is no longer with the Company, as previously disclosed. On November 25, 2024, the SEC filed a complaint in the United States District Court for the Southern District of New York against Mr. Leech alleging violations of certain laws related to trade allocations. Concurrently, the DOJ filed an indictment with the United States District Court for the Southern District of New York against Mr. Leech for similar allegations and for false statements made to the SEC. On July 3, 2025, Franklin, WAM and Ken Leech were named as defendants in a lawsuit filed by the Western PA Electrical Employees Insurance Trust Fund in the U.S. District Court for the Western District of Pennsylvania seeking class certification on behalf of shareholders of two funds managed by WAM for the period January 1, 2021 through October 31, 2023. The plaintiff is pursuing claims under the Securities Exchange Act of 1934 against all defendants in connection with trade allocations made by Mr. Leech in that period that are also the subject of the investigations reported above. The plaintiff is seeking, among other things, damages, interest, and costs and expenses, including attorneys’ fees. Franklin Templeton 401(k) Retirement Plan Litigation. On July 22, 2025, Franklin and the Franklin Templeton 401(k) Retirement Plan Committee were named as defendants in a lawsuit filed by certain former employees in the U.S. District Court for the Northern District of California. The plaintiffs seek to represent a class of participants and beneficiaries of the Franklin Templeton 401(k) Retirement Plan (the “Plan”) who were invested in funds managed by the Company at any time on or after July 22, 2019. The plaintiffs are pursuing claims under the Employee Retirement Income Security Act of 1974 for alleged breaches of fiduciary duties and failure to monitor the Plan fiduciaries in connection with the Plan’s inclusion of certain proprietary funds as investment options. The plaintiffs are seeking, among other things, damages, disgorgement, removal of certain investments from the Plan, removal and replacement of the Plan’s fiduciaries, attorneys’ fees and costs, and pre-judgment interest. The lawsuits reported above against the Company are in their preliminary stages. Management believes the claims made in the lawsuits are without merit and the Company intends to defend against them vigorously. The Company cannot predict the outcome of these lawsuits or estimate any reasonably possible loss or range of loss that may arise from any negative outcome. Other Litigation and Regulatory Matters. The Company is from time to time involved in other litigation relating to claims arising in the normal course of business. Management is of the opinion that the ultimate resolution of such claims will not materially affect the Company’s business, financial position, results of operations or liquidity. In management’s opinion, an adequate accrual has been made as of September 30, 2025 to provide for any probable losses that may arise from such matters for which the Company could reasonably estimate an amount. Indemnifications and Guarantees In the ordinary course of business or in connection with certain acquisition agreements, the Company enters into contracts that provide for indemnifications by the Company in certain circumstances. In addition, certain Company entities guarantee certain financial and performance-related obligations of various Franklin subsidiaries. The Company is also subject to certain legal requirements and agreements providing for indemnifications of directors, officers and personnel against liabilities and expenses they may incur under certain circumstances in connection with their service. The terms of these indemnities and guarantees vary pursuant to applicable facts and circumstances, and from agreement to agreement. Future payments for claims against the Company under these indemnities or guarantees could negatively impact the Company’s financial condition. In management’s opinion, no material loss was deemed probable or reasonably possible pursuant to such indemnification agreements and/or guarantees as of September 30, 2025. Other Commitments and Contingencies While the Company has no legal or contractual obligation to do so, it routinely makes cash investments in the course of launching sponsored funds. At September 30, 2025, the Company had $520.8 million of committed capital contributions which relate to discretionary commitments to invest in sponsored funds and other investment products and entities, including CIPs. These unfunded commitments are not recorded in the Company’s consolidated balance sheet.
