The following table presents the notional amounts and gross fair values of the Company’s derivatives, as well as the balance sheet netting adjustments on an aggregate basis as of September 30, 2022 and December 31, 2021. The derivative asset and liability fair values are presented on a gross basis prior to the application of bilateral collateral and master netting agreements, but after the application of variation margin payments as settlements with central clearing organizations. Total derivative asset and liability fair values are adjusted to take into consideration the effects of legally enforceable master netting agreements and cash collateral received or paid as of September 30, 2022 and December 31, 2021. The resulting net derivative asset and liability fair values are included in Other assets and Accrued expenses and other liabilities, respectively, on the Consolidated Balance Sheet.

(2)The notional amount of the Company’s commodity contracts entered with its customers totaled 8,199 thousand barrels of crude oil and 113,574 thousand units of natural gas, measured in million British thermal units (“MMBTUs”) as of September 30, 2022. In comparison, the notional amount of the Company’s commodity contracts entered with its customers totaled 7,519 thousand barrels of crude oil and 83,274 thousand MMBTUs of natural gas as of December 31, 2021. The Company simultaneously entered into the offsetting commodity contracts with mirrored terms with third-party financial institutions.

Cash Flow Hedges — The Company hedges the variability of forecasted cash flows due to changes in contractually specified interest rates associated with floating-rate assets/liabilities and other forecasted transactions. As of September 30, 2022, $2.25 billion and $275.0 million in notional amounts of interest rate contracts were designated as cash flow hedges to modify the interest rate characteristics of certain commercial loans and borrowings, respectively, from variable to fixed. This will reduce the impact of changes in future cash flows due to changes in market interest rates. Changes in the fair values of cash flow hedges are recognized in AOCI and reclassified to earnings in the same period when the hedged cash flows impact earnings. Considering the interest rates, yield curve and notional amounts as of September 30, 2022, the Company expects to reclassify an estimated $26.5 million of after-tax net losses related to cash flow hedges from AOCI into earnings during the next 12 months.

The following table presents the pre-tax changes in AOCI from cash flow hedges for the three and nine months ended September 30, 2022 and 2021. The after-tax impact of cash flow hedges on AOCI is discussed in Note 13 — Accumulated Other Comprehensive Income (Loss) to the Consolidated Financial Statements in this Form-10-Q.

Net Investment Hedges — ASC 830-20, Foreign Currency Matters — Foreign Currency Transactions and ASC 815, Derivatives and Hedging, allows hedging of the foreign currency risk of a net investment in a foreign operation. The Company enters into foreign currency forward contracts to hedge a portion of the Bank’s investment in East West Bank (China) Limited, a non-USD functional currency subsidiary in China. The hedging instruments designated as net investment hedges involve hedging the risk of changes in the USD equivalent value of a designated monetary amount of the Bank’s net investment in East West Bank (China) Limited, against the risk of adverse changes in the foreign currency exchange rate of the Chinese Renminbi (“RMB”). The Company may de-designate the net investment hedges when the Company expects the hedge will cease to be highly effective.

Interest Rate Contracts — The Company enters into interest rate contracts, which include interest rate swaps and options with its customers to allow the customers to hedge against the risk of rising interest rates on their variable-rate loans.

Credit Contracts — The Company periodically enters into credit RPAs with institutional counterparties to manage the credit exposure of the interest rate contracts associated with syndication loans. The Company may enter into protection sold or protection purchased RPAs. A purchaser of credit protection that enters into an interest rate contract with the borrower, may in turn enter into an RPA with a seller of protection, under which the seller of protection receives a fee to accept a portion of the credit risk. The seller of credit protection is required to make payments to the purchaser if the underlying borrower defaults on the related interest rate contract. Credit risk on RPAs is managed by monitoring the credit worthiness of the borrowers and the institutional counterparties, which is part of the normal credit review and monitoring process. The majority of the referenced entities of the protection sold RPAs were investment grade as of both September 30, 2022 and December 31, 2021. Assuming the underlying borrowers referenced in the interest rate contracts defaulted in the protection sold RPAs, there would be no maximum exposure as of September 30, 2022 and $3.2 million of maximum exposure as of December 31, 2021. The weighted-average remaining maturities of the outstanding protection sold RPAs were 2.7 years and 3.2 years as of September 30, 2022 and December 31, 2021, respectively.

Equity Contracts — From time to time, as part of the Company’s loan origination process, the Company obtains warrants to purchase preferred and/or common stock of technology and life science companies to which it provides loans. Warrants grant the Company the right to buy a certain class of the underlying company’s equity at a certain price before expiration. The Company held warrants in one public company and 13 private companies as of September 30, 2022, and held warrants in one public company and 12 private companies as of December 31, 2021. The total fair value of the warrants held was $346 thousand and $220 thousand as of September 30, 2022 and December 31, 2021, respectively.

Commodity Contracts — The Company enters into energy commodity contracts in the form of swaps and options with its commercial loan customers, to allow them to hedge against the risk of energy commodity price fluctuation. To economically hedge against the risk and exposure of commodity price fluctuation in the products offered to its commercial loan customers, the Company enters into offsetting commodity contracts with third-party financial institutions, including central clearing organizations.

Credit Risk-Related Contingent Features — The Company’s over-the-counter derivative contracts may contain early termination provisions that require the Company to settle any outstanding balances upon the occurrence of a specified credit risk-related event. Such event primarily relates to a downgrade in the credit rating of East West Bank to below investment grade. As of September 30, 2022, the aggregate fair value amounts of all derivative instruments with credit risk-related contingent features that were in a net liability position totaled $9.8 million, in which $8.4 million of collateral was posted to cover these positions. In comparison, as of December 31, 2021, the aggregate fair value amounts of all derivative instruments with credit risk-related contingent features that were in a net liability position totaled $66.8 million, in which $66.6 million of collateral was posted to cover these positions. In the event that the credit rating of East West Bank had been downgraded to below investment grade, minimal additional collateral would have been required to be posted as of September 30, 2022 and December 31, 2021.

The following tables present the gross derivative asset and liability fair values, the balance sheet netting adjustments and the resulting net fair values recorded on the consolidated balance sheet, as well as the cash and noncash collateral associated with master netting arrangements. The gross amounts of derivative asset and liability fair values are presented after the application of variation margin payments as settlements with central counterparties, where applicable. The collateral amounts in the following tables are limited to the outstanding balances of the related asset or liability, after the application of netting; therefore, instances of overcollateralization are not shown:
