 the applicable alternative reference rate. Such an undertaking would be time consuming and costly. Despite such efforts, the manner and impact of the transition and related developments, as well as the effect of such developments on our funding costs, investment and trading securities portfolios, and business, would be uncertain and could have a material adverse impact on our profitability.

Our financial instruments expose us to certain market risks and may increase the volatility of earnings and AOCI.

We hold certain financial instruments measured at fair value. For those financial instruments measured at fair value, we are required to recognize changes in fair value in either earnings or AOCI each quarter. Therefore, any increases or decreases in the fair value of these financial instruments will have a corresponding impact on reported earnings or AOCI. Fair value can be affected by a variety of factors, many of which are beyond our control, including credit spreads, interest rate volatility, liquidity, and other economic factors. Accordingly, we are subject to mark-to-market risk and the application of fair value accounting which may cause our earnings and AOCI to be more volatile than what may be suggested by our underlying performance.

Due to the inherent risk associated with accounting estimates, our ACL may be insufficient, which could require us to raise additional capital or otherwise adversely affect our financial condition and results of operations.

Credit losses are an inherent risk in the business of making loans. Management makes various assumptions and judgments about the collectability of our loan portfolio and maintains an ACL estimated to cover expected losses over the life of the loans in our portfolio. The measurement of expected credit losses takes place at the time the financial asset is first added to the balance sheet (with periodic updates thereafter) and is based on a number of factors, including the size of the portfolio, asset classifications, economic trends, industry experience and trends, industry and geographic concentrations, estimated collateral values, management’s assessment of the credit risk inherent in the portfolio, loan underwriting policies, historical loan loss experience, and reasonable and supportable forecasts. In addition, with the exception of residential loans, we individually evaluate all loans identified as problem loans with a total commitment of $1.0 million or more, and establish an allowance based upon our estimation of the potential loss associated with those problem loans. Additions to the ACL recorded through provision for credit losses decrease our net income. If management’s assumptions and judgments are incorrect or if economic conditions worsen compared to forecast, our actual credit losses may exceed our ACL.

At December 31, 2024, our ACL on funded loans and loss contingency on unfunded loan commitments
