EAST WEST BANCORP INC

Credit risk is the risk that a borrower or a counterparty will fail to perform according to the terms and conditions of a loan, investment or derivative and expose the Company to loss. Credit risk exists with many of the Company’s assets and exposures such as loans, debt securities and certain derivatives. The majority of the Company’s credit risk is associated with lending activities.

The ROC has primary oversight responsibility for the identified enterprise risk categories including credit risk. The ROC monitors management’s assessment of asset quality, credit risk trends, credit quality administration, underwriting standards, and portfolio credit risk management strategies and processes, such as diversification and liquidity, all of which enable management to control credit risk. At the management level, the Credit Risk Management Committee has primary oversight responsibility for credit risk. The Senior Credit Supervision function manages credit policy for the line of business transactional credit risk, assuring that all exposure is risk-rated according to the requirements of the credit risk rating policy. The Senior Credit Supervision function, in connection with the ERM function, also evaluates and reports the overall credit risk exposure to senior management and the ROC, including concentration limits and key risk indicators. Reporting directly to the Board’s Audit Committee, the IAR function provides additional validation support to the Company’s robust credit risk management culture by performing an independent and objective assessment of underwriting and documentation quality, and serves as an assurance function for the risk rating of the Company’s loan portfolios. A key focus of our credit risk management is adherence to a well-controlled underwriting and loan monitoring process.

The Company assesses the overall performance and credit quality of the loans held-for-investment portfolio through an integrated analysis of specific performance ratios. This approach forms the basis of the discussion in the sections immediately following: Credit Quality, Nonperforming Assets and Allowance for Credit Losses.

Credit Quality

The Company utilizes a credit risk rating system to assist in monitoring credit quality. Loans are evaluated using the Company’s internal credit risk rating of 1 through 10. For more information on the Company’s credit quality indicators and internal credit risk ratings, refer to Note 6 — Loans Receivable and Allowance for Credit Losses to the Consolidated Financial Statements in this Form 10-Q.

The following table presents the Company’s criticized loans as of September 30, 2025 and December 31, 2024:

(1)Consists of substandard, doubtful and loss categories.

Criticized loans increased $18 million or 2%, to $1.2 billion during the nine months ended September 30, 2025, primarily driven by higher criticized CRE loans, partially offset by lower criticized C&I loans and multifamily residential loans.

Nonperforming Assets

Nonperforming assets are comprised of nonaccrual loans, OREO and other nonperforming assets. Other nonperforming assets and OREO are repossessed assets and properties, respectively, acquired through foreclosure, or through full or partial satisfaction of loans held-for-investment. Nonperforming assets may also include nonperforming loans HFS.

The following table presents nonperforming assets information as of September 30, 2025 and December 31, 2024:

Loans are generally placed on nonaccrual status at the earlier of when they become 90 days past due or when the full collection of principal or interest becomes uncertain, regardless of the length of past due status. Collectability is generally assessed based on economic and business conditions, the borrower’s financial condition, and the adequacy of collateral, if any. For additional details regarding the Company’s nonaccrual loan policy, see Note 1 — Summary of Significant Accounting Policies — Significant Accounting Policies — Loans Held-for-Investment to the Consolidated Financial Statements in the Company’s 2024 Form 10-K.

Nonaccrual loans of $157 million as of September 30, 2025 decreased $2 million or 1% from December 31, 2024. The decrease was primarily due to the transfer of a commercial and a multifamily residential nonaccrual loan to OREO, charge-offs of certain commercial nonaccrual loans and one construction nonaccrual loan, and a payment received on a commercial nonaccrual loan. As of September 30, 2025, $32 million or 20% of nonaccrual loans were less than 90 days delinquent. In comparison, $49 million or 31% of nonaccrual loans were less than 90 days delinquent as of December 31, 2024.

The following table presents the accruing loans past due by portfolio segment as of September 30, 2025 and December 31, 2024:
