Note 6 —Loans Receivable and Allowance for Credit Losses

The following table presents the composition of the Company’s loans held-for-investment outstanding as of September 30, 2025 and December 31, 2024:

(1)Includes$24 million and $46 million of net deferred loan fees and net unamortized premiums as of September 30, 2025 and December 31, 2024, respectively.

Accrued interest receivable on loans held-for-investment was $252 million and $255 million as of September 30, 2025 and December 31, 2024, respectively, and was included in Other assets on the Consolidated Balance Sheet. The interest income recognized on nonaccrual loans was $6 million for each of the three and nine months ended September 30, 2025, compared with immaterial amounts for the corresponding prior year periods. The interest income reversed was insignificant for each of the three and nine months ended September 30, 2025 and 2024. For the Company’s accounting policy on accrued interest receivable related to loans held-for-investment, see Note 1 — Summary of Significant Accounting Policies — Significant Accounting Policies — Loans Held-for-Investmentto the Consolidated Financial Statements of the Company’s 2024 Form 10-K. The Company may occasionally have loans held-for-sale. For the Company’s accounting policy on loans held-for-sale, refer to Note 1 — Summary of Significant Accounting Policies — Significant Accounting Policies — Loans Held-for-Sale to the Consolidated Financial Statements in the Company’s 2024 Form 10-K.

The Company’s FRB and FHLB borrowings are primarily secured by loans held-for-investment. Loans held-for-investment totaling$40.9 billion and $38.2 billion, respectively, were pledged to secure borrowings and provide additional borrowing capacity as of September 30, 2025 and December 31, 2024.

Credit Quality Indicators

All loans are subject to the Company’s credit review and monitoring process. For the commercial loan portfolio, loans are risk rated based on an analysis of the borrower’s current payment performance or delinquency, repayment sources, financial and liquidity factors, including industry and geographic considerations. For the consumer loan portfolio, payment performance or delinquency is typically the driving indicator for risk ratings.

The Company utilizes internal credit risk ratings to assign each individual loan a risk rating of 1 through 10:

•Pass — loans risk rated 1 through 5 are assigned an internal risk rating category of “Pass.” Loans risk rated 1 are typically loans fully secured by cash. Pass loans have sufficient sources of repayment to repay the loan in full, in accordance with all terms and conditions.

•Special mention — loans assigned a risk rating of 6 have potential weaknesses that warrant closer attention by management; these are assigned an internal risk rating category of “Special Mention.”

•Substandard — loans assigned a risk rating of 7 or 8 have well-defined weaknesses that may jeopardize the full and timely repayment of the loan; these are assigned an internal risk rating category of “Substandard.”

•Doubtful — loans assigned a risk rating of 9 have insufficient sources of repayment and a high probability of loss; these are assigned an internal risk rating category of “Doubtful.”

•Loss — loans assigned a risk rating of 10 are uncollectible and of such little value that they are no longer considered bankable assets; these are assigned an internal risk rating category of “Loss.”

Loan exposures categorized as criticized consist of special mention, substandard, doubtful and loss categories. The Company reviews the internal risk ratings of its loan portfolio on a regular basis, and adjusts the ratings based on changes in the borrowers’ financial status and the collectability of the loans.

The following tables summarize the Company’s loans held-for-investment and year-to-date gross write-offs by loan portfolio segments, internal risk ratings and vintage year as of the periods presented. The vintage year is the year of loan origination, renewal or major modification. Gross write-offs in the following tables are for the nine months ended September 30, 2025, and the year ended December 31, 2024. Revolving loans that are converted to term loans presented in the tables below are excluded from the term loans by vintage year columns.

(1)No revolving commercial loans were converted to term loans during each of the three months ended September 30, 2025 and 2024. $16 million of total commercial loans, comprised of C&I revolving loans, and$8 million of total commercial loans, comprised of C&I and CRE revolving loans, were converted to term loans during the nine months ended September 30, 2025 and 2024, respectively. $1 million of total consumer loans, comprised of HELOCs, were converted to term loans during the three and nine months ended September 30, 2025. In comparison,$2 million and $26 million of total consumer loans, comprised of HELOCs, were converted to term loans during the three and nine months ended September 30, 2024, respectively.

(2)Excludes gross write-offs associated with loans the Company sold or settled.

(3)$1 million of nonaccrual loans whose payments were guaranteed by the Federal Housing Administration were classified with a “Pass” rating as of both September 30, 2025 and December 31, 2024.

Nonaccrual and Past Due Loans

Loans that are 90 or more days past due are generally placed on nonaccrual status unless the loan is well-collateralized and in the process of collection. Loans that are less than 90 days past due but have identified deficiencies, such as when the full collection of principal or interest becomes uncertain, are also placed on nonaccrual status. The following tables present the aging analysis of loans held-for-investment as of September 30, 2025 and December 31, 2024:

The following table presents the amortized cost of loans on nonaccrual status for which there was no related ALLL as of both September 30, 2025 and December 31, 2024. Nonaccrual loans may not have an allowance for credit losses if the loan balances are well secured by collateral values and there is no loss expectation.

Foreclosed Assets

The Company acquires assets from borrowers through loan restructurings, workouts, or foreclosures. Assets acquired may include real properties (e.g., real estate, land, and buildings) and commercial and personal properties. The Company recognizes foreclosed assets upon receiving assets in satisfaction of a loan (e.g., taking legal title or physical possession).

Foreclosed assets, consisting of OREO and other nonperforming assets, are included in Other assets on the Consolidated Balance Sheet. The Company had $24 million of foreclosed assets as of September 30, 2025, compared with $35 million as of December 31, 2024. The Company commences the foreclosure process on consumer mortgage loans after a borrower becomes more than 120 days delinquent in accordance with the Consumer Financial Protection Bureau guidelines. The carrying value of the consumer real estate loans that were in an active or suspended foreclosure process was $21 million and $16 million as of September 30, 2025 and December 31, 2024, respectively.

Loan Modifications to Borrowers Experiencing Financial Difficulty

As part of the Company’s loss mitigation efforts, the Company may agree to modify the contractual terms of a loan to assist borrowers experiencing financial difficulty. The Company negotiates loan modifications on a case-by-case basis to achieve mutually agreeable terms that maximize loan collectability and meet the borrower’s financial needs. The Company considers various factors to identify borrowers experiencing financial difficulty. The primary factor for consumer loan borrowers is delinquency status. For commercial loan borrowers, these factors include credit risk ratings, the probability of loan risk rating downgrades, and overall risk profile changes. The modification may include, but is not limited to, payment delays, interest rate reductions, term extensions, principal forgiveness, or a combination of such modifications. Commercial loan borrowers that require immaterial modifications such as insignificant interest rate changes, short-term extensions (90 days or less) from the original maturity date, or temporary waivers or extensions of financial covenants which would not constitute material credit actions, are generally not considered to be experiencing financial difficulty and are not included in the disclosure. Insignificant payment deferrals (three months or less in the last 12 months) are also not included in the disclosure.

The following tables present the amortized cost of loans that were modified during the three and nine months ended September 30, 2025 and 2024 by loan class and modification type:

The following table presents the financial effects of the loan modifications for the three and nine months ended September 30, 2025 and 2024 by loan class and modification type:

A modified loan may become delinquent and may result in a payment default (generally 90 days past due) subsequent to modification. The following tables present the amortized cost basis of modified loans that, within 12 months of the modification date, experienced a subsequent default during the three and nine months ended September 30, 2025 and 2024.

The Company monitors the performance of modified loans to borrowers experiencing financial difficulty to understand the effectiveness of its modification efforts. The following tables present the performance of loans that were modified over the last 12 months as of September 30, 2025 and 2024:

As of September 30, 2025 and December 31, 2024, commitments to lend additional funds to borrowers whose loans were modified totaled $14 million and $10 million, respectively.

Allowance for Credit Losses

The Company has a current expected credit losses framework for all financial assets measured at amortized cost and certain off-balance sheet credit exposures. The Company’s allowance for credit losses, which includes both the ALLL and the allowance for unfunded credit commitments, is calculated with the objective of maintaining a reserve sufficient to absorb losses inherent in our credit portfolios. The measurement of the allowance for credit losses is based on management’s best estimate of lifetime expected credit losses, periodic evaluation of the loan portfolio, lending-related commitments and other relevant factors.

The allowance for credit losses is deducted from the amortized cost basis of a financial asset or a group of financial assets so that the balance sheet reflects the net amount the Company expects to collect. Amortized cost is the principal balance outstanding, net of purchase premiums and discounts, deferred fees and costs, and escrow advances. Subsequent changes in expected credit losses are recognized in net income as a provision for, or a reversal of, credit loss expense.

The allowance for credit losses estimation involves procedures to consider the unique risk characteristics of the portfolio segments. The majority of the Company’s credit exposures that share risk characteristics with other similar exposures are collectively evaluated. The collectively evaluated loans include performing loans and unfunded credit commitments. If an exposure does not share risk characteristics with other exposures, the Company generally estimates expected credit losses on an individual basis.

ALLL for Collectively Evaluated Loans

The allowance for collectively evaluated loans consists of a quantitative component that assesses the different risk factors considered in our models and a qualitative component that considers risk factors external to the models. Each of these components are described below.

Quantitative Component— The Company applies quantitative methods to estimate ALLL by considering a variety of factors such as historical loss experience, the current credit quality of the portfolio, and an economic outlook over the life of the loan. The Company incorporates forward-looking information using macroeconomic scenarios which include variables that are considered key drivers of increases and decreases in credit losses. The Company utilizes a probability-weighted, multiple-scenario forecast approach. These scenarios may consist of a base forecast representing management's view of the most likely outcome, combined with downside or upside scenarios reflecting possible worsening or improving economic conditions. The quantitative models incorporate a probability-weighted calculation of these macroeconomic scenarios over a reasonable and supportable forecast period. If the life of the loans extends beyond the reasonable and supportable forecast period, the Company will consider historical experience or long-run macroeconomic trends over the remaining life of the loans to estimate the ALLL.

There were no changes to the reasonable and supportable forecast period and reversion to the historical loss experience method for the three and nine months ended September 30, 2025 and 2024.

The following table provides key credit risk characteristics and macroeconomic variables that the Company uses to estimate the expected credit losses by portfolio segment:

Quantitative Component—ALLL for the Commercial Loan Portfolio

The Company’s C&I lifetime loss rate model estimates the loss rate expected over the life of a loan. This loss rate is applied to the amortized cost basis, excluding accrued interest receivable, to determine expected credit losses. The lifetime loss rate model’s reasonable and supportable period spans eight quarters, thereafter, immediately reverting to the historical average loss rate, expressed through the loan-level lifetime loss rate.

To generate estimates of expected loss at the loan level for CRE, multifamily residential, and construction and land loans, projected probabilities of default (“PDs”) and loss given defaults (“LGDs”) are applied to the estimated exposure at default, considering the term and payment structure of the loan. The forecast of future economic conditions returns to long-run historical economic trends within the reasonable and supportable period. To estimate the life of a loan under both models, the contractual term of the loan is adjusted for estimated prepayments based on historical prepayment experience.

Quantitative Component—ALLL for the Consumer Loan Portfolio

For single-family residential and HELOC loans, projected PDs and LGDs are applied to the estimated exposure at default, considering the term and payment structure of the loan, to generate estimates of expected loss at the loan level. The forecast of future economic conditions returns to long-run historical economic trends after the reasonable and supportable period. To estimate the life of a loan for the single-family residential and HELOC loan portfolios, the contractual term of the loan is adjusted for estimated prepayments based on historical prepayment experience. For other consumer loans, the Company uses a loss rate approach.

Qualitative Component— The Company considers the following qualitative factors in the determination of the collectively evaluated allowance if these factors have not already been captured by the quantitative model. Such qualitative factors may include, but are not limited to:

•loan growth trends;

•the volume and severity of past due financial assets, and criticized or adversely classified financial assets;

•the Company’s lending policies and procedures, including changes in lending strategies, underwriting standards, collection, write-off and recovery practices;

•knowledge of a borrower’s operations;

•the quality of the Company’s credit review system;

•the experience, ability and depth of the Company’s management and associates;

•the effect of other external factors such as the regulatory and legal environments, or changes in technology;

•actual and expected changes in international, national, regional, and local economic and business conditions in which the Company operates; and

•risk factors in certain industry sectors not captured by the quantitative models.

The magnitude of the impact of these factors on the Company’s qualitative assessment of the allowance for credit losses changes from period to period according to changes made by management in its assessment of these factors. The extent to which these factors change may be dependent on whether they are already reflected in quantitative loss estimates during the current period and the extent to which changes in these factors diverge from period to period.

While the Company’s allowance methodologies strive to reflect all relevant credit risk factors, there continues to be uncertainty associated with, but not limited to, potential imprecision in the estimation process due to the inherent time lag of obtaining information and normal variations between expected and actual outcomes. The Company may hold additional qualitative reserves that are designed to provide coverage for losses attributable to such risk.

ALLL for Individually Evaluated Loans

When a loan no longer shares similar risk characteristics with other loans, such as in the case of certain nonaccrual loans, the Company estimates the ALLL on an individual loan basis. The ALLL for individually evaluated loans is measured as the difference between the recorded value of the loans and their fair value. For loans evaluated individually, the Company uses one of three different asset valuation measurement methods: (1) the fair value of collateral less costs to sell; (2) the present value of expected future cash flows; or (3) the loan's observable market price. If an individually evaluated loan is determined to be collateral dependent, the Company applies the fair value of the collateral less costs to sell method. If an individually evaluated loan is determined not to be collateral dependent, the Company uses the present value of future cash flows or the observable market value of the loan.

•Collateral-Dependent Loans —The allowance of a collateral-dependent loan is limited to the difference between the recorded value and fair value of the collateral less cost of disposal or sale. As of September 30, 2025, collateral-dependent commercial and consumer loans totaled $39 million and $14 million, respectively. In comparison, collateral-dependent commercial and consumer loans totaled $45 million and $23 million, respectively, as of December 31, 2024. The Company's collateral-dependent loans were secured by real estate. As of both September 30, 2025 and December 31, 2024, the collateral value of the properties securing the collateral-dependent loans, net of selling costs, exceeded the recorded value of the majority of the loans.

The following tables summarize the activity in the ALLL by portfolio segments for the three and nine months ended September 30, 2025 and 2024:

In addition to the ALLL, the Company maintains an allowance for unfunded credit commitments. The Company has three general areas for which it provides the allowance for unfunded credit commitments: (1) recourse obligations for loans sold, (2) letters of credit, and (3) unfunded lending commitments. The allowance for unfunded credit commitments is maintained at a level that management believes to be sufficient to absorb estimated expected credit losses related to unfunded credit facilities. See Note 10 — Commitments and Contingenciesto the Consolidated Financial Statements in this Form 10-Q for additional information related to unfunded credit commitments. The following table summarizes the activity in the allowance for unfunded credit commitments for the three and nine months ended September 30, 2025 and 2024:

The allowance for credit losses was$839 million as of September 30, 2025, an increase of $97 million, compared with $742 million as of December 31, 2024. The increase in the allowance for credit losses was primarily driven by the Company’s net loan and commitment growth, qualitative risk assessment, and an economic outlook that reflected continued caution regarding inflation, the high-interest rate environment and potential impacts from the escalating tariff and global trade tensions.

The Company considers multiple economic scenarios to develop the estimate of the ALLL. The scenarios may consist of a baseline forecast representing management's view of the most likely outcome, and downside or upside scenarios that reflect possible worsening or improving economic conditions. As of September 30, 2025, the Company assigned a slightly lower weighting to its upside scenario, while applying a slightly higher weighting to the downside scenario, with baseline remaining the same as compared with December 31, 2024. The current baseline economic forecast continues to reflect key risks such as still-elevated interest rates, inflation exacerbated by higher tariffs, and slowing job growth. Compared with December 2024, the September 2025 baseline forecast for GDP growth is projected to be weaker in the near-term for the remainder of 2025 and into 2026. Similarly, the near- and mid-term unemployment rates have increased in the September 2025 forecast reflecting the uncertainty which businesses and households are facing. The downside scenario assumed the economy falls into recession in the fourth quarter of 2025 as a result of tariffs, deportations, rising inflation, elevated interest rates, global and domestic political tensions, and reduced credit availability. The upside scenario assumed a more optimistic economic outlook, including stronger growth, stable financial markets, unemployment declining below baseline starting in the fourth quarter of 2025, and diminished global political and economic tension.

Loan Transfers, Sales and Purchases

The Company’s primary business focus is on directly originated loans. The Company also purchases loans from and participates in loan financing with other banks. In the normal course of business, the Company also provides other financial institutions with the ability to participate in commercial loans that it originates, by selling loans to such institutions. Purchased loans may be transferred from held-for-investment to held-for-sale, and write-downs to ALLL are recorded, when appropriate. The following tables provide information on the carrying value of loans transferred, sold and purchased, during the three and nine months ended September 30, 2025 and 2024:

(1)Includes write-downs of $2 million to the allowance for loan losses related to loans transferred from held-for-investment to held-for-sale for the nine months ended September 30, 2025, and $1 million and $2 million for the three and nine months ended September 30, 2024, respectively.

(2)Includes originated loans sold of $37 million and $159 million for the three and nine months ended September 30, 2025, respectively, and $309 million and $496 million for the three and nine months ended September 30, 2024, respectively. Originated loans sold were primarily comprised of C&I loans for each of the three and nine months ended September 30, 2025 and 2024.

(3)Includes $90 million and $97 million of purchased loans sold in the secondary market for the three and nine months ended September 30, 2025, and $20 million and $156 million for the three and nine months ended September 30, 2024, respectively.

(4)C&I loan purchases were comprised of syndicated C&I term loans.
