TFS Financial Corporation, a federally chartered stock holding company, conducts its principal activities through its wholly owned subsidiaries. The principal line of business of the Company is retail consumer banking, including mortgage lending, deposit gathering and, to a much lesser extent, other financial services. As of December 31, 2022, approximately 81% of the Company’s outstanding shares were owned by the federally chartered mutual holding company, Third Federal Savings and Loan Association of Cleveland, MHC. The thrift subsidiary of TFS Financial Corporation is Third Federal Savings and Loan Association of Cleveland.

The accounting and financial reporting policies followed by the Company conform in all material respects to U.S. GAAP and to general practices in the financial services industry. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates. The allowance for credit losses, the valuation of deferred tax assets, and the determination of pension obligations are particularly subject to change.
