Variable interest entities and asset securitizations | Variable interest entities and asset securitizations The Company’s securitization activity includes securitizing loans originated for sale into government issued or guaranteed mortgage-backed securities. The Company has not recognized any material losses as a result of having securitized assets. In March 2024, M&T Bank issued asset-backed notes secured by automobile loans. Approximately $526 million of such loans were sold into a special purpose trust which in turn issued asset-backed notes to investors. The loans continue to be serviced by the Company. A total of $511 million of such notes, representing the senior-most notes in the securitization, were purchased by third parties. Those asset-backed notes had a weighted-average estimated life of approximately two years and a weighted-average interest rate of 5.29% at the time of securitization. Additionally, $15 million of certificates representing the residual interests of the trust were retained by the Company. As a result of the retention of the residual interests and its continued role as servicer of the loans, the Company is considered to be the primary beneficiary of the securitization trust and, accordingly, the trust has been included in the Company's consolidated financial statements. At June 30, 2024, the remaining balance of the loans and leases in trust was $457 million and the outstanding asset-backed notes issued to third party investors was $446 million. M&T has issued junior subordinated debentures payable to various trusts that have issued preferred capital securities. M&T owns the common securities of those trust entities. The Company is not considered to be the primary beneficiary of those entities and, accordingly, the trusts are not included in the Company’s consolidated financial statements. At each of June 30, 2024 and December 31, 2023, the Company included the junior subordinated debentures as “long-term borrowings” in its Consolidated Balance Sheet and recognized $22 million in other assets for its “investment” in the common securities of the trusts that will be concomitantly repaid to M&T by the respective trust from the proceeds of M&T’s repayment of the junior subordinated debentures associated with preferred capital securities. The Company has invested as a limited partner in various partnerships that collectively had total assets of approximately $9.5 billion and $9.8 billion at June 30, 2024 and December 31, 2023, respectively. Those partnerships generally construct or acquire properties, including properties and facilities that produce renewable energy, for which the investing partners are eligible to receive certain federal income tax credits in accordance with government guidelines. Such investments may also provide tax deductible losses to the partners. The partnership investments also assist the Company in achieving its community reinvestment initiatives. The Company, in its position as limited partner, does not direct the activities that most significantly impact the economic performance of the partnerships and, therefore, the partnership entities are not included in the Company's consolidated financial statements. The Company’s investments in qualified affordable housing projects are accounted for using the proportional amortization method whereby those investments are amortized to "income taxes" in the Consolidated Statement of Income as tax credits and other tax benefits resulting from deductible losses associated with the projects are received. Effective January 1, 2024, the Company adopted amended guidance which permits an election to account for other tax equity investments using the proportional amortization method if certain conditions are met. The Company has elected to apply the proportional amortization method to eligible renewable energy and certain other tax credit investments in addition to the low income housing tax credit investments for which the proportional amortization method had previously been applied. Information on the Company's carrying amount of its investments in tax equity partnerships and its related future funding commitments are presented in the following table:

_______________________________________________________________ (a)Included in "accrued interest and other assets" in the Consolidated Balance Sheet. (b)Included in "accrued interest and other liabilities" in the Consolidated Balance Sheet. The reduction to income tax expense recognized from the Company's investments in partnerships accounted for using the proportional amortization method was $8 million (net of $45 million of investment amortization) and $10 million (net of $41 million of investment amortization) for the three months ended June 30, 2024 and 2023, respectively and $15 million (net of $88 million of investment amortization) and $16 million (net of $82 million of investment amortization) for the six months ended June 30, 2024 and 2023, respectively. The net reduction to income tax expense has been reported in "net change in other accrued income and expense" in the Consolidated Statement of Cash Flows. While the Company has elected to apply the proportional amortization method for renewable energy credit investments, at June 30, 2024 no such investments met the eligibility criteria for application of that method. The reduction to income tax expense recognized from renewable energy credit investments was $9 million and $20 million for the three-month and six-month periods ended June 30, 2024, respectively, and $4 million and $12 million for the three-month and six-month periods ended June 30, 2023, respectively. As a limited partner, there is no recourse to the Company by creditors of the partnerships. However, the tax credits that result from the Company’s investments in such partnerships are generally subject to recapture should a partnership fail to comply with the respective government regulations. The Company has not provided financial or other support to the partnerships that was not contractually required. Although the Company currently estimates that no material losses are probable, its maximum exposure to loss from its investments in such partnerships as of June 30, 2024 was $2.2 billion, including possible recapture of certain tax credits. The Company serves as investment advisor for certain registered money-market funds. The Company has no explicit arrangement to provide support to those funds, but may waive portions of its allowable management fees as a result of market conditions.
