Business	1. BUSINESS The condensed consolidated financial statements include CVB Financial Corp. (referred to herein on an unconsolidated basis as “CVB” and on a consolidated basis as “we”, “our” or the “Company”) and its wholly owned subsidiary: Citizens Business Bank (the “Bank” or “CBB”), after elimination of all intercompany transactions and balances. The Company has one inactive subsidiary, Chino Valley Bancorp. The Company’s primary operations are related to traditional banking activities. This includes the acceptance of deposits and the lending and investing of money through the operations of the Bank. The Bank also provides trust and investment-related services to customers through its CitizensTrust Division. The Bank’s customers consist primarily of small to mid-sized businesses and individuals located in the Inland Empire, Los Angeles County, Orange County, San Diego County, Ventura County, Santa Barbara County, and the Central Valley area of California. As of September 30, 2022, the Bank operated 63 banking centers and four trust office locations. The Company is headquartered in the city of Ontario, California. On January 7, 2022, we completed the acquisition of Suncrest Bank ("Suncrest") with approximately $ 1.4 billion in total assets, acquired at fair value, and seven banking centers. Total assets at September 30, 2022 included $ 765.9 million of acquired net loans at fair value, $ 131.1 million of investment securities, and $ 9 million in Bank-Owned Life Insurance ("BOLI"). The acquisition resulted in $ 102.1 million of goodwill and $ 3.9 million in core deposit premium. Net cash proceeds were used to fund the $ 39.6 million in cash paid to the former shareholders of Suncrest as part of the merger consideration. Refer to Note 4 – Business Combinations of the notes to the unaudited condensed consolidated financial statements of this report for additional information.

Basis of Presentation	2. BASIS OF PRESENTATION The accompanying unaudited condensed consolidated financial statements and notes thereto have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”) for Form 10-Q and conform to practices within the banking industry and include all of the information and disclosures required by accounting principles generally accepted in the United States of America (“GAAP”) for interim financial reporting. The accompanying unaudited condensed consolidated financial statements reflect all adjustments (consisting only of normal recurring adjustments), which are necessary for a fair presentation of financial results for the interim periods presented. The results of operations for the three and nine months ended September 30, 2022 are not necessarily indicative of the results for the full year. Certain information and note disclosures normally included in annual financial statements prepared in accordance with GAAP have been condensed or omitted. These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements, accounting policies and financial notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2021, filed with the SEC. A summary of the significant accounting policies consistently applied in the preparation of the accompanying unaudited condensed consolidated financial statements follows. Reclassification — Certain amounts in the prior periods’ unaudited condensed consolidated financial statements and related footnote disclosures have been reclassified to conform to the current presentation with no impact on previously reported net income or stockholders’ equity.

Summary of Significant Accounting Policies	3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Except as discussed below, our accounting policies are described in Note 3 – Summary of Significant Accounting Policies , of our audited consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2021 as filed with the SEC (“Form 10-K”). Use of Estimates in the Preparation of Financial Statements — The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. A material estimate that is particularly susceptible to significant change in the near term relates to the determination of the allowance for credit losses. Other significant estimates, which may be subject to change, include fair value determinations and disclosures, impairment of investments, goodwill, loans, as well as valuation of deferred tax assets.

Business Combinations [Abstract]
Business combinations	4. BUSINESS COMBINATIONS On January 7, 2022, the Company completed the acquisition of Suncrest, headquartered in Visalia, California. The Company acquired all of the assets and assumed all of the liabilities of Suncrest in a stock and cash transaction for $ 39.6 million in cash and $ 197.1 million in stock. As a result, Suncrest merged with and into the Bank, the principal subsidiary of CVB. The Company believes this transaction serves to further extend and strengthen its geographic presence in California’s Central Valley and the Sacramento metro area. At close, Suncrest had seven branch locations and two loan production offices, which re-opened as CBB locations on January 10, 2022. As a result of the consolidation of two branches during the second quarter of 2022, five branch locations remain from this acquisition. The total fair value of assets acquired approximated $ 1.38 billion in total assets, including $ 329.0 million of cash and cash equivalents, net of cash paid, $ 131.1 million of investment securities, $ 765.9 million in net loans, $ 6.1 million in premises and equipment, $ 9.0 million in BOLI, and $ 33.7 million in other assets. The purchased credit deteriorated (“PCD”) loans were recorded at a fair value of $ 224.7 million, which was net of a discount of $ 13.1 million including a credit discount of $ 8.6 million. The assets acquired also include a core deposit intangible of $ 3.9 million and non-tax deductible goodwill of $ 102.1 million. Goodwill from the acquisition represents the excess of the purchase price over the fair value of the net tangible and intangible assets acquired. The total fair value of liabilities assumed was $ 1.19 billion, which included $ 512.8 million of noninterest-bearing deposits and $ 669.8 million of interest-bearing deposits, and $ 6.2 million in other liabilities. The assets and liabilities, both tangible and intangible, were recorded at their estimated fair values as of January 7, 2022. The assets acquired and liabilities assumed have been accounted for under the acquisition method of accounting. These fair values are estimates and are subject to adjustment for up to one year after the acquisition date or when additional information relative to the closing date fair values becomes available and such information is considered final, whichever is earlier. For the assets acquired and liabilities assumed, the Company considers the fair value of the net loans and the related deferred tax asset to be provisional, specifically the PCD loans, while the Company obtains additional information relevant to the fair value. We have included the financial results of the business combination in the condensed consolidated statement of earnings and comprehensive income beginning on the acquisition date. Supplementary pro forma financial information related to the acquisition is not included because the impact to the Company's consolidated statements of income is not material. For the nine months ended September 30, 2022 , the Company incurred non-recurring merger related expenses associated with the Suncrest acquisition of $ 6.0 million.

Investment securities are classified as either available-for-sale securities or held-to-maturity securities. The fair value is based on quoted prices for similar assets in active markets or quoted prices for identical assets in markets that are not active. Estimated fair values were obtained from an independent pricing service based upon market quotes. Rising interest rates over the last nine months have resulted in declines in fair value for the majority of our investment securities, as reflected in the total unrealized holding loss in the following table.

The remaining securities are predominately AA or better general-obligation municipal bonds. The allowance for credit losses for held-to-maturity investment securities under the CECL model was zero at September 30, 2022 and December 31, 2021. We adopted ASU 2016-13 on January 1, 2020, on a modified retrospective basis. Under this ASU, once it is determined that a credit loss has occurred, an allowance for credit losses is established on our available-for-sale ("AFS") and held-to-maturity ("HTM") securities. Management determined that there were no credit losses for securities in an unrealized loss position as of September 30, 2022 and December 31, 2021. The following table presents the Company’s investment securities, by investment category, in an unrealized loss position for which an allowance for credit losses has not been recorded as of September 30, 2022 and December 31, 2021.

The amortized cost and fair value of debt securities at September 30, 2022, by contractual maturity, are shown in the table below. Although mortgage-backed and CMO/REMIC securities have weighted average remaining contractual maturities of approximately 23 yea rs, expected maturities will differ from contractual maturities because borrowers may have the right to prepay such obligations without penalty. Mortgage-backed and CMO/REMIC securities are included in maturity categories based upon estimated average lives which incorporate estimated prepayment speeds.

The Company’s real estate loans and construction loans are secured by real properties primarily located in California. As of September 30, 2022, $ 486.4 million, or 7.28 % of the total commercial real estate loans included lo ans secured by farmland, compared to $ 364.4 million, or 6.29 %, at December 31, 2021. The loans secured by farmland included $ 136.9 million for loans secured by dairy & livestock land and $ 349.5 million for loans secured by agricultural land at September 30, 2022 , compared to $ 134.9 million for loans secured by dairy & livestock land and $ 229.5 million for loans secured by agricultural land at December 31, 2021. As of September 30, 2022 , dairy & livestock and agribusiness loans of $ 323.1 million were comprised of $ 264.7 million for dairy & livestock loans and $ 58.4 million for agribusiness loans. This compares to $ 34.5 of agribusiness loans included in the $ 386.2 million dairy & livestock and agribusiness loans as of December 31, 2021. At September 30, 2022 and December 31, 2021, loans totaling $ 4.33 b illion and $ 3.96 billion, respectively, were pledged to secure available lines of credit from the FHLB and the Federal Reserve Bank. There were no outstanding loans held-for-sale as of September 30, 2022 and December 31, 2021. Credit Quality Indicators We monitor credit quality by evaluating various risk attributes and utilize such information in our evaluation of the appropriateness of the allowance for credit losses. Internal credit risk ratings, within our loan risk rating system, are the credit quality indicators that we most closely monitor. An important element of our approach to credit risk management is our loan risk rating system. The originating officer assigns each loan an initial risk rating, which is reviewed and confirmed or changed, as appropriate, by credit management. Approvals are made based upon the amount of inherent credit risk specific to the transaction and are reviewed for appropriateness by senior line and credit management personnel. Credits are monitored by line and credit management personnel for deterioration or improvement in a borrower’s financial condition, which would impact the ability of the borrower to perform under the contract. Risk ratings are adjusted as necessary. Loans are risk rated into the following categories: Pass, Special Mention, Substandard, Doubtful and Loss. Each of these groups is assessed for the proper amount to be used in determining the adequacy of our allowance for losses. These categories can be described as follows: Pass — These loans, including loans on the Bank’s internal watch list, range from minimal credit risk to lower than average, but still acceptable, credit risk. Watch list loans usually require more than normal management attention. Loans on the watch list may involve borrowers with adverse financial trends, higher debt/equity ratios, or weaker liquidity positions, but not to the degree of being considered a defined weakness or problem loan where risk of loss may be apparent. Special Mention — Loans assigned to this category have potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in the deterioration of the repayment prospects for the asset or the Company’s credit position at some future date. Special mention assets are not adversely classified and do not expose the Company to sufficient risk to warrant adverse classification. Substandard — Loans classified as substandard are inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any. Assets so classified must have a well-defined weakness, or weaknesses, that jeopardize the liquidation of the debt. Substandard loans are characterized by the distinct possibility that the Company will sustain some loss if deficiencies are not corrected. Doubtful — Loans classified as doubtful have all the weaknesses inherent in those classified substandard with the added characteristic that the weaknesses make collection or the liquidation in full, on the basis of currently existing facts, conditions and values, highly questionable and improbable. Loss — Loans classified as loss are considered uncollectible and of such little value that their continuance as bankable assets is not warranted. This classification does not mean that the loan has absolutely no recovery or salvage value, but rather that it is not practical or desirable to defer writing off this asset with insignificant value even though partial recovery may be affected in the future. The following table summarizes loans by type and origination year, including acquired Suncrest loans in the year of origination, according to our internal risk ratings as of the dates presented.

We measure the expected credit losses on a collective (pooled) basis for those loans that share similar risk characteristics. We have three collective loan pools: Commercial Real Estate, Commercial and Industrial, and Consumer. Our ACL amounts are largely driven by portfolio characteristics, including loss history and various risk attributes, and the economic outlook for certain macroeconomic variables. Risk attributes for commercial real estate loans include Original Loan to Value ratios ("OLTV"), origination year, loan seasoning, and macroeconomic variables that include GDP growth, commercial real estate price index and unemployment rate. Risk attributes for commercial and industrial loans include internal risk ratings, borrower industry sector, loan credit spreads and macroeconomic variables that include unemployment rate and BBB spread. The macroeconomic variables for Consumer include unemployment rate and GDP. The Commercial Real Estate methodology is applied over commercial real estate loans, a portion of construction loans, and a portion of SBA loans (excluding Paycheck Protection Program loans). The Commercial and Industrial methodology is applied over a substantial portion of the Company’s commercial and industrial loans, all dairy & livestock and agribusiness loans, municipal lease receivables, as well as the remaining portion of SBA loans (excluding Paycheck Protection Program loans). The Consumer methodology is applied to SFR mortgage loans, consumer loans, as well as the remaining construction loans. In addition to determining the quantitative life of loan loss rate to be applied against the amortized cost basis of the portfolio segments, management reviews current conditions and forecasts to determine whether adjustments are needed to ensure that the life of loan loss rates reflect both the current state of the portfolio, and expectations for macroeconomic changes. Our methodology for assessing the appropriateness of the allowance is reviewed on a regular basis and considers overall risks in the Bank’s loan portfolio. Refer to Note 3 – Summary of Significant Accounting Policies included in our Annual Report on Form 10-K for the year ended December 31, 2021 for a more detailed discussion concerning the allowance for credit losses. The ACL totaled $ 82.6 million at September 30, 2022 , compared to $ 65.0 million at December 31, 2021 . As a result of the acquisition of Suncrest, we recorded a provision for credit loss of $ 4.9 million on January 7, 2022 to establish the ACL for the acquired loans that were not considered PCD. The ACL at January 7, 2022, also included $ 8.6 million for the acquired Suncrest PCD loans. The $ 17.6 million increase in the ACL from December 31, 2021 to September 30, 2022 is comprised of approximately $ 877,000 in net recoveries, the $ 8.6 million for the Suncrest PCD loans and an $ 8.1 million provision for credit losses, including the $ 4.9 million provision recorded to establish the ACL for the non-PCD loans acquired from Suncrest. At September 30, 2022 , the ACL as a percentage of total loans and leases, at amortized cost, was 0.94 %, or 0.94 % of total loans when excluding the $ 17.3 million in PPP loans. This compares to 0.82 % and 0.84 % at December 31, 2021 , respectively. Net recoveries were $ 877,000 for the nine months ended September 30, 2022 , which compares to $ 2.8 million in net charge-off s for the same period of 2021. Our economic forecast continues to be a blend of multiple forecasts produced by Moody’s. These U.S. economic forecasts include a baseline forecast, as well as multiple downside forecasts. The baseline forecast continues to represent the largest weighting in our multi-weighted forecast scenario, with downside risks weighted among multiple forecasts. Our weighted forecast assumes GDP will increase by 0.4 % in 2023, 1.6 % for 2024 and then grow by 2.5 % in 2025. The unemployment rate is forecasted to be 5 % in 2023, 5.3 % in 2024 and then decline to 5.1 % in 2025. Management believes that the ACL was appropriate at September 30, 2022 and December 31, 2021. Due to inflationary pressures, rising interest rates and geopolitical events, no assurance can be given that economic conditions that adversely affect the Company’s service areas or other circumstances will not be reflected in increased provisions for credit losses in the future.

The Bank’s Credit Management Division is in charge of monitoring asset quality, establishing credit policies and procedures and enforcing the consistent application of these policies and procedures across the Bank. Reviews of nonperforming, past due loans and larger credits, designed to identify potential charges to the allowance for credit losses, are conducted on an ongoing basis. These reviews consider such factors as the financial strength of borrowers and any guarantors, the value of the applicable collateral, loan loss experience, estimated credit losses, prevailing economic conditions, and other factors.

The Company evaluates credit risk associated with the off-balance sheet loan commitments in the same manner as it evaluates credit risk associated with the loan and lease portfolio. The Bank's ACL methodology produced an allowance of $ 8.0 million for the off-balance sheet credit exposures as of September 30, 2022 . There was no provision or recapture of provision for unfunded loan commitments for the nine months ended September 30, 2022, compared to a $ 1.0 million recapture of provision for unfunded loan commitments for the nine months ended September 30, 2021. As of September 30, 2022 and December 31, 2021 , the balance in this reserve was $ 8.0 million and was included in other liabilities. Troubled Debt Restructurings (“TDRs”) Loans that are reported as TDRs are considered impaired and charge-off amounts are taken on an individual loan basis, as deemed appropriate. The majority of restructured loans are loans for which the terms of repayment have been renegotiated, resulting in a reduction in interest rate or deferral of principal. Refer to Note 3 – Summary of Significant Accounting Policies, included in our Annual Report on Form 10-K for the year ended December 31, 2021 for a more detailed discussion regarding TDRs. As of September 30, 2022 , there were $ 5.8 million of loans classified as a TDR, all of which were performing. TDRs on accrual status are comprised of loans that were accruing interest at the time of restructuring or have demonstrated repayment performance in compliance with the restructured terms for a sustained period and for which the Company anticipates full repayment of both principal and interest. At September 30, 2022, performing TDRs were comprised of four commercial and industrial loans of $ 4.8 million and five SFR mortgage loans totaling $ 1.0 million. The majority of TDRs have no specific allowance allocated as any impairment amount is normally charged off at the time the loan is considered uncollectible. We have no allocated allowance to TDRs as of September 30, 2022 and December 31, 2021. The following table provides a summary of the activity related to TDRs for the periods presented. Three months ended Nine months ended 2022 2021 2022 2021 (Dollars in thousands) Performing TDRs: Beginning balance $ 5,198 $ 8,215 $ 5,293 $ 2,159 New modifications 3,204 - 3,204 7,096 Payoffs/payments, net and other ( 2,574 ) ( 240 ) ( 2,669 ) ( 1,280 ) TDRs returned to accrual status - - - - TDRs placed on nonaccrual status - - - - Ending balance $ 5,828 $ 7,975 $ 5,828 $ 7,975 Nonperforming TDRs: Beginning balance $ - $ - $ - $ - New modifications - - - - Charge-offs - - - - Payoffs/payments, net and other - - - - TDRs returned to accrual status - - - - TDRs placed on nonaccrual status - - - - Ending balance $ - $ - $ - $ - Total TDRs $ 5,828 $ 7,975 $ 5,828 $ 7,975 The following tables summarize loans modified as TDRs for the period presented.

Earnings Per Share [Abstract]
Earnings Per Share Reconciliation	7. EARNINGS PER SHARE RECONCILIATION Basic earnings per common share are computed by dividing income allocated to common stockholders by the weighted-average number of common shares outstanding during each period. The computation of diluted earnings per common share considers the number of shares issuable upon the assumed exercise of outstanding common stock options. Antidilutive common shares are not included in the calculation of diluted earnings per common share. For the three and nine months ended September 30, 2022 shares deemed to be antidilutive, and thus excluded from the computation of earnings per common share, were 66,000 and 247,000 , respectively. For the three and nine months ended September 30, 2021 shares deemed to be antidilutive, and thus excluded from the computation of earnings per common share, were 321,000 and 114,000 , respectively. The table below shows earnings per common share and diluted earnings per common share, and reconciles the numerator and denominator of both earnings per common share calculations.

Fair Value Information	. FAIR VALUE INFORMATION Fair Value Hierarchy Fair value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The valuation methodologies for financial assets and liabilities measured at fair value on a recurring and non-recurring basis are described in Note 18 — Fair Value Information, included in our Annual Report on Form 10-K for the year ended December 31, 2021. Assets and Liabilities Measured at Fair Value on a Recurring Basis The tables below present the balances of assets and liabilities measured at fair value on a recurring basis as of the dates presented.

These adjustments to fair value usually result from application of lower of cost or fair value accounting or impairment write-downs of individual assets. For assets measured at fair value on a non-recurring basis that were held on the balance sheet at September 30, 2022 and December 31, 2021 , respectively, the following tables provide the level of valuation assumptions used to determine each adjustment and the carrying value of the related assets that had losses during the period. These losses on collateral dependent loans represent the amount of the allowance for credit losses and/or charge-offs during the period applicable to loans held at period-end. The amount of the allowance is included in the ACL.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	9. DERIVATIVE FINANCIAL INSTRUMENTS The Bank is exposed to certain risks relating to its ongoing business operations and utilizes interest rate swap agreements (“swaps”) as part of its asset/liability management strategy to help manage its interest rate risk position. As of September 30, 2022 , the Bank has entered into 127 interest-rate swap agreements with customers with a notional amount totaling $ 436.9 million. The Bank then entered into identical offsetting swaps with a counterparties. The swap agreements are not designated as hedging instruments. The purpose of entering into offsetting derivatives not designated as a hedging instrument is to provide the Bank a variable-rate loan receivable and to provide the customer the financial effects of a fixed-rate loan without creating significant volatility in the Bank’s earnings. The structure of the swaps is as follows. The Bank enters into an interest rate swap with its customers in which the Bank pays the customer a variable rate and the customer pays the Bank a fixed rate, therefore allowing customers to convert variable rate loans to fixed rate loans. At the same time, the Bank enters into a swap with the counterparty bank in which the Bank pays the counterparty a fixed rate and the counterparty in return pays the Bank a variable rate. The net effect of the transaction allows the Bank to receive interest on the loan from the customer at a variable rate based on LIBOR, plus a spread. As LIBOR is expected to be phased out in 2023, the Bank will use multiple alternative indices as replacements for LIBOR. The changes in the fair value of the swaps primarily offset each other and therefore should not have a significant impact on the Company’s results of operations, although the Company does incur credit and counterparty risk with respect to performance on the swap agreements by the Bank’s customer and counterparty, respectively. As a result of the Bank exceeding $10 billion in assets, federal regulations required the Bank, beginning in January 2019, to clear most interest rate swaps through a clearing house (“centrally cleared”). These instruments contain language outlining collateral pledging requirements for each counterparty, in which collateral must be posted if market value exceeds certain agreed upon threshold limits. Cash or securities are pledged as collateral. Our interest rate swap derivatives are subject to a master netting arrangement with our counterparties. None of our derivative assets and liabilities are offset in the Company’s condensed consolidated balance sheet. We believe our risk of loss associated with our counterparty borrowers related to interest rate swaps is mitigated as the loans with swaps are underwritten to take into account potential additional exposure, although there can be no assurances in this regard since the performance of our swaps is subject to market and counterparty risk. Balance Sheet Classification of Derivative Financial Instruments As of September 30, 2022 and December 31, 2021, the total notional amount of the Company’s swaps was $ 436.9 million, and $ 493.2 million, respectively. The location of the asset and liability, and their respective fair values, ar e summarized in the tables below.

Balance Sheet Offsetting	11. BALANCE SHEET OFFSETTING Assets and liabilities relating to certain financial instruments, including, derivatives and securities sold under repurchase agreements (“repurchase agreements”), may be eligible for offset in the condensed consolidated balance sheets as permitted under accounting guidance. As noted above, our interest rate swap derivatives are subject to master netting arrangements. Our interest rate swap derivatives require the Company to pledge investment securities as collateral based on certain risk thresholds. Investment securities that have been pledged by the Company to counterparties continue to be reported in the Company’s condensed consolidated balance sheets unless the Company defaults. We offer a repurchase agreement product to our customers, which include master netting agreements that allow for the netting of collateral positions. This product, known as Citizens Sweep Manager, sells certain of our securities overnight to our customers under an agreement to repurchase them the next day. The repurchase agreements are not offset in the Company’s condensed consolidated balances.

Use of Estimates in the Preparation of Financial Statements	Use of Estimates in the Preparation of Financial Statements — The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. A material estimate that is particularly susceptible to significant change in the near term relates to the determination of the allowance for credit losses. Other significant estimates, which may be subject to change, include fair value determinations and disclosures, impairment of investments, goodwill, loans, as well as valuation of deferred tax assets.

The Bank’s Credit Management Division is in charge of monitoring asset quality, establishing credit policies and procedures and enforcing the consistent application of these policies and procedures across the Bank. Reviews of nonperforming, past due loans and larger credits, designed to identify potential charges to the allowance for credit losses, are conducted on an ongoing basis. These reviews consider such factors as the financial strength of borrowers and any guarantors, the value of the applicable collateral, loan loss experience, estimated credit losses, prevailing economic conditions, and other factors.

The Company evaluates credit risk associated with the off-balance sheet loan commitments in the same manner as it evaluates credit risk associated with the loan and lease portfolio. The Bank's ACL methodology produced an allowance of $ 8.0 million for the off-balance sheet credit exposures as of September 30, 2022 . There was no provision or recapture of provision for unfunded loan commitments for the nine months ended September 30, 2022, compared to a $ 1.0 million recapture of provision for unfunded loan commitments for the nine months ended September 30, 2021. As of September 30, 2022 and December 31, 2021 , the balance in this reserve was $ 8.0 million and was included in other liabilities. Troubled Debt Restructurings (“TDRs”) Loans that are reported as TDRs are considered impaired and charge-off amounts are taken on an individual loan basis, as deemed appropriate. The majority of restructured loans are loans for which the terms of repayment have been renegotiated, resulting in a reduction in interest rate or deferral of principal. Refer to Note 3 – Summary of Significant Accounting Policies, included in our Annual Report on Form 10-K for the year ended December 31, 2021 for a more detailed discussion regarding TDRs. As of September 30, 2022 , there were $ 5.8 million of loans classified as a TDR, all of which were performing. TDRs on accrual status are comprised of loans that were accruing interest at the time of restructuring or have demonstrated repayment performance in compliance with the restructured terms for a sustained period and for which the Company anticipates full repayment of both principal and interest. At September 30, 2022, performing TDRs were comprised of four commercial and industrial loans of $ 4.8 million and five SFR mortgage loans totaling $ 1.0 million. The majority of TDRs have no specific allowance allocated as any impairment amount is normally charged off at the time the loan is considered uncollectible. We have no allocated allowance to TDRs as of September 30, 2022 and December 31, 2021. The following table provides a summary of the activity related to TDRs for the periods presented.

Description of Conditions Relating to Clearing of Interest rate Swaps	As a result of the Bank exceeding $10 billion in assets, federal regulations required the Bank, beginning in January 2019, to clear most interest rate swaps through a clearing house (“centrally cleared”). These instruments contain language outlining collateral pledging requirements for each counterparty, in which collateral must be posted if market value exceeds certain agreed upon threshold limits. Cash or securities are pledged as collateral.
