Accounting Policies [Abstract]
Significant Accounting Policies and Basis of Presentation	SIGNIFICANT ACCOUNTING POLICIES AND BASIS OF PRESENTATION Basis of Presentation The interim unaudited consolidated financial statements have been prepared in conformity with U.S. GAAP and pursuant to the rules and regulations of the SEC. These interim unaudited consolidated financial statements reflect all normal and recurring adjustments that are, in the opinion of management, necessary to present a fair statement of the financial position and the results of operations and cash flows of Customers Bancorp and subsidiaries for the interim periods presented. Certain information and footnote disclosures normally included in the annual consolidated financial statements have been omitted from these interim unaudited consolidated financial statements as permitted by SEC rules and regulations. The December 31, 2021 consolidated balance sheet presented in this report has been derived from Customers Bancorp’s audited 2021 consolidated financial statements. Management believes that the disclosures are adequate to present fairly the consolidated financial statements as of the dates and for the periods presented. These interim unaudited consolidated financial statements should be read in conjunction with the 2021 consolidated financial statements of Customers Bancorp and subsidiaries included in Customers' Annual Report on Form 10-K for the year ended December 31, 2021 filed with the SEC on February 28, 2022 (the "2021 Form 10-K"). The 2021 Form 10-K describes Customers Bancorp’s significant accounting policies. There have been no material changes to Customers Bancorp's significant accounting policies noted above for the three and six months ended June 30, 2022. Customers Bancorp completed the divestiture of BankMobile Technologies, Inc., the technology arm of its BankMobile segment, to MFAC Merger Sub Inc., an indirect wholly-owned subsidiary of MFAC on January 4, 2021. Following the completion of the divestiture of BMT, BankMobile's serviced deposits and loans and the related net interest income have been combined with Customers’ financial condition and the results of operations as a single reportable segment. BMT's operating results and associated cash flows have been presented as "Discontinued operations" within the accompanying consolidated financial statements and prior period amounts have been reclassified to conform with the current period presentation. See NOTE 3 – DISCONTINUED OPERATIONS for additional information. Recently Issued Accounting Standards Presented below are recently issued accounting standards that the FASB has issued but are not yet effective. Accounting Standards Issued But Not Yet Adopted Standard Summary of Guidance Effects on Financial Statements ASU 2022-02, Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures Issued March 2022 • Eliminates the accounting guidance for TDRs by creditors, and applies the loan refinancing and restructuring guidance when a borrower is experiencing financial difficulty to determine whether a modification results in a new loan or a continuation of an existing loan. • Provides enhanced disclosure requirements for certain loan refinancing and restructurings and disclosure of current-period gross write-offs by year of origination for financing receivables and net investments in leases within the scope of ASC 326. • Effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Early adoption is permitted, including adoption in any interim period, provided the amendments are adopted as of the beginning of the fiscal year that includes the interim period of adoption. Early adoption is permitted separately for the amendments to TDRs and vintage disclosures. • TDR and vintage disclosures are to be adopted prospectively. An entity may adopt TDR recognition and measurement guidance prospectively or elect to use a modified retrospective transition method, with a cumulative effect adjustment to retained earnings at the beginning of the period of adoption. • Customers expects this guidance will result in additional disclosures related to gross write-offs by vintage year and expansive disclosures for certain loan modifications to borrowers experiencing financial difficulty.

Discontinued Operations and Disposal Groups [Abstract]
Discontinued Operations	DISCONTINUED OPERATIONS On January 4, 2021, Customers Bancorp completed the divestiture of BMT, the technology arm of its BankMobile segment, to MFAC Merger Sub Inc., an indirect wholly-owned subsidiary of MFAC. Following the completion of the divestiture of BMT, BankMobile's serviced deposits and loans and the related net interest income have been combined with Customers' financial condition and the results of operations as a single reportable segment. Customers received cash consideration of $23.1 million upon closing of the divestiture and $3.7 million of additional cash consideration in May 2021. Upon closing of the divestiture, the holders of Customers Bancorp's common stock who held their shares as of the close of business on December 18, 2020 became entitled to receive an aggregate of 4,876,387 shares of BM Technologies' common stock. Customers distributed 0.15389 shares of BM Technologies common stock for each share of Customers Bancorp's common stock held as of the close of business on December 18, 2020 as special dividends. Certain team members of BMT also received 1,348,748 restricted shares of BM Technologies' common stock in the form of severance payments. The total stock consideration from the divestiture that was distributed to holders of Customers Bancorp's common stock and certain BMT team members represented 52% of the outstanding common stock of BM Technologies at the closing date of the divestiture. The sale of BMT was accounted for as a sale of non-controlling interest and the merger between BMT and MFAC was accounted for as a reverse recapitalization as BMT was considered to be the accounting acquirer. Upon closing of the transaction, Customers had no remaining investment in BM Technologies. BMT's historical financial results for periods prior to the divestiture are reflected in Customers Bancorp’s consolidated financial statements as discontinued operations. BMT's operating results and associated cash flows have been presented as "Discontinued operations" within the accompanying consolidated financial statements and prior period amounts have been reclassified to conform with the current period presentation. The following summarized financial information related to BMT has been segregated from continuing operations and reported as discontinued operations for the periods presented.

During the three and six months ended June 30, 2021, Customers recognized unrealized gains of $1.7 million and $2.7 million respectively, on its equity securities issued by a foreign entity that were held by CB Green Ventures Pte Ltd. and CUBI India Ventures Pte Ltd. These unrealized gains and losses were reported as unrealized gain (loss) on investment securities within non-interest income on the consolidated statements of income. Customers' transactions with unconsolidated VIEs include sales of consumer installment loans and investments in the securities issued by the VIEs. Customers is not the primary beneficiary of the VIEs because Customers has no right to make decisions that will most significantly affect the economic performance of the VIEs. Customers' continuing involvement with the unconsolidated VIEs is not significant. Customers' continuing involvement is not considered to be significant where Customers only invests in securities issued by the VIE and was not involved in the design of the VIE or where Customers has transferred financial assets to the VIE for only cash consideration. Customers' investments in the securities issued by the VIEs are classified as AFS debt securities on the consolidated balance sheets, and represent Customers' maximum exposure to loss. Proceeds from the sale of AFS debt securities were $399.0 million and $555.0 million for the three and six months ended June 30, 2022, respectively. Proceeds from the sale of AFS debt securities were $53.7 million and $407.6 million for the three and six months ended June 30, 2021, respectively.

The following table presents AFS debt securities by stated maturity.

Except for the four asset-backed securities where there was a deterioration in future estimated cash flows as further discussed below, the unrealized losses were principally due to changes in market interest rates that resulted in a negative impact on the respective securities' fair value and are expected to be recovered when market prices recover or at maturity. Customers does not intend to sell any of the 147 securities, and it is not more likely than not that Customers will be required to sell any of the 147 securities before recovery of the amortized cost basis. At December 31, 2021, there were 117 AFS debt securities in an unrealized loss position. Customers recorded an allowance for credit losses on four asset-backed securities where there was a deterioration in future estimated cash flows during the three and six months ended June 30, 2022. A discounted cash flow approach is used to determine the amount of the allowance. The cash flows expected to be collected, after considering expected prepayments, are discounted at the original effective interest rate. The amount of the allowance is limited to the difference between the amortized cost basis of the security and its estimated fair value. The following tables present the activity in the allowance for credit losses on AFS debt securities, by major security type, for the periods presented: Asset-backed securities (amounts in thousands) Three Months Ended Balance at April 1 $ 728 Credit losses on securities for which credit losses were not previously recorded 329 Net increase (decrease) in allowance for credit losses on previously impaired securities (646) Balance at June 30 $ 411 Asset-backed securities (amounts in thousands) Six Months Ended Balance at January 1 $ — Credit losses on securities for which credit losses were not previously recorded 411 Balance at June 30 $ 411 At June 30, 2022 and December 31, 2021, Customers Bank had pledged investment securities aggregating $19.3 million and $11.3 million in fair value, respectively, as collateral primarily for unused lines of credit with another financial institution. The counterparty does not have the ability to sell or repledge these securities. At June 30, 2022 and December 31, 2021, no securities holding of any one issuer, other than the U.S. government and its agencies, amounted to greater than 10% of shareholders' equity. Investment securities held to maturity In June 2022, Customers transferred $500.2 million in net carrying value of certain debt securities from available for sale to held to maturity as a part of Customers' ongoing asset liability management primarily to mitigate the impact of rising interest rates on the long duration component of the investment portfolio. At the time of transfer to held to maturity, these debt securities had unrealized losses of $50.0 million, which, along with the unrealized loss in accumulated other comprehensive income, will be amortized over the remaining terms of the securities as an adjustment to yield (interest income) using the effective interest method resulting in no impact to current period earnings. The amortized cost, approximate fair value and allowance for credit losses of investment securities held to maturity as of June 30, 2022 are summarized as follows: June 30, 2022 (1) (amounts in thousands) Amortized Cost Allowance for Credit Losses Net Carrying Value Gross Unrealized Gains Gross Unrealized Losses Fair Value Held to maturity debt securities: Agency-guaranteed residential mortgage-backed securities $ 7,820 $ — $ 7,820 $ — $ (181) $ 7,639 Agency-guaranteed commercial mortgage-backed securities 1,966 — 1,966 — (5) 1,961 Agency-guaranteed residential collateralized mortgage obligations 215,996 — 215,996 — (4,368) 211,628 Agency-guaranteed commercial collateralized mortgage obligations 154,204 — 154,204 4 (1,041) 153,167 Private label collateralized mortgage obligations 115,053 — 115,053 — (3,813) 111,240 Total held to maturity debt securities $ 495,039 $ — $ 495,039 $ 4 $ (9,408) $ 485,635 (1) Accrued interest on HTM debt securities totaled $0.7 million at June 30, 2022, and is included in accrued interest receivable on the consolidated balance sheet. The following table presents HTM debt securities by stated maturity. Debt securities backed by mortgages and other assets have expected maturities that differ from contractual maturities because borrowers have the right to call or prepay and, therefore, these debt securities are classified separately with no specific maturity date: June 30, 2022 (amounts in thousands) Amortized Fair Agency-guaranteed residential mortgage-backed securities $ 7,820 $ 7,639 Agency-guaranteed commercial mortgage-backed securities 1,966 1,961 Agency-guaranteed residential collateralized mortgage obligations 215,996 211,628 Agency-guaranteed commercial collateralized mortgage obligations 154,204 153,167 Private label collateralized mortgage obligations 115,053 111,240 Total held to maturity debt securities $ 495,039 $ 485,635 Customers recorded no allowance for credit losses on investment securities classified as held to maturity at June 30, 2022. The U.S. government agency securities represent obligations issued by a U.S. government-sponsored enterprise or other federal government agency that are explicitly or implicitly guaranteed by the U.S. federal government and therefore, assumed to have zero credit losses. The private label collateralized mortgage obligations are highly rated with sufficient overcollateralization and therefore have zero expected credit losses. The unrealized losses on HTM debt securities with no ACL were due to changes in market interest rates that resulted in a negative impact on the respective securities' fair value and are expected to be recovered when market prices recover or at maturity. Credit Quality Indicators Customers monitors the credit quality of HTM debt securities primarily through credit ratings provided by rating agencies. Investment grade debt securities are rated BBB- or higher by S&P Global Ratings, Baa3 or higher by Moody's Investors Service or equivalent ratings by other rating agencies, and are generally considered to be of low credit risk. All of the HTM debt securities held by Customers were investment grade or U.S. government agency guaranteed securities that were not rated at June 30, 2022.

At June 30, 2022, there were no HTM debt securities past due under the terms of their agreements or in nonaccrual status.

Loans and Leases Receivable and Allowance for Credit Losses on Loans and Leases	LOANS AND LEASES RECEIVABLE AND ALLOWANCE FOR CREDIT LOSSES ON LOANS AND LEASES The following table presents loans and leases receivable as of June 30, 2022 and December 31, 2021. (amounts in thousands) June 30, 2022 December 31, 2021 Loans and leases receivable, mortgage warehouse, at fair value $ 1,874,603 $ 2,284,325 Loans receivable, PPP 1,570,160 3,250,008 Loans and leases receivable: Commercial: Commercial and industrial, including specialty lending (1) 5,737,670 3,424,783 Multi-family 2,008,784 1,486,308 Commercial real estate owner occupied 710,577 654,922 Commercial real estate non-owner occupied 1,152,869 1,121,238 Construction 195,687 198,981 Total commercial loans and leases receivable 9,805,587 6,886,232 Consumer: Residential real estate 457,768 334,730 Manufactured housing 48,570 52,861 Installment 1,901,070 1,744,475 Total consumer loans receivable 2,407,408 2,132,066 Loans and leases receivable 12,212,995 9,018,298 Allowance for credit losses on loans and leases (156,530) (137,804) Total loans and leases receivable, net of allowance for credit losses on loans and leases (2) $ 15,501,228 $ 14,414,827 (1) Includes direct finance equipment leases of $149.2 million and $146.5 million at June 30, 2022 and December 31, 2021, respectively. (2) Includes deferred (fees) costs and unamortized (discounts) premiums, net of $(12.1) million and $(52.0) million at June 30, 2022 and December 31, 2021, respectively. Customers' total loans and leases receivable portfolio includes loans receivable which are reported at fair value based on an election made to account for these loans at fair value and loans and leases receivable which are predominately reported at their outstanding unpaid principal balance, net of charge-offs and deferred costs and fees and unamortized premiums and discounts and are evaluated for impairment. The total amount of accrued interest recorded for total loans was $86.1 million and $81.6 million at June 30, 2022 and December 31, 2021, respectively, and is presented in accrued interest receivable in the consolidated balance sheet. At June 30, 2022 and December 31, 2021, there were $17.2 million and $38.9 million of individually evaluated loans that were collateral-dependent, respectively. Substantially all individually evaluated loans are collateral-dependent and consisted primarily of commercial and industrial, commercial real estate, and residential real estate loans. Collateral-dependent commercial and industrial loans were secured by accounts receivable, inventory and equipment; collateral-dependent commercial real estate loans were secured by commercial real estate assets; and residential real estate loans were secured by residential real estate assets. Loans receivable, mortgage warehouse, at fair value Mortgage warehouse loans consist of commercial loans to mortgage companies. These mortgage warehouse lending transactions are subject to master repurchase agreements. As a result of the contractual provisions, for accounting purposes, control of the underlying mortgage loan has not transferred and the rewards and risks of the mortgage loans are not assumed by Customers. The mortgage warehouse loans are designated as loans held for investment and reported at fair value based on an election made to account for the loans at fair value. Pursuant to the agreements, Customers funds the pipelines for these mortgage lenders by sending payments directly to the closing agents for funded mortgage loans and receives proceeds directly from third party investors when the underlying mortgage loans are sold into the secondary market. The fair value of the mortgage warehouse loans is estimated as the amount of cash initially advanced to fund the mortgage, plus accrued interest and fees, as specified in the respective agreements. The interest rates on these loans are variable, and the lending transactions are short-term, with an average life under 30 days from purchase to sale. The primary goal of these lending transactions is to provide liquidity to mortgage companies. At June 30, 2022 and December 31, 2021, all of Customers' commercial mortgage warehouse loans were current in terms of payment. As these loans are reported at their fair value, they do not have an ACL and are therefore excluded from ACL-related disclosures. Loans receivable, PPP Customers had $1.6 billion and $3.3 billion of PPP loans outstanding as of June 30, 2022 and December 31, 2021, respectively, which are fully guaranteed by the SBA and earn a fixed interest rate of 1.00%. Customers recognized interest income, including origination fees, of $20.6 million and $57.5 million for the three and six months ended June 30, 2022, respectively. Customers recognized interest income, including origination fees, of $41.1 million and $79.9 million for the three and six months ended June 30, 2021, respectively. PPP loans include an embedded credit enhancement from the SBA, which guarantees 100% of the principal and interest owed by the borrower provided that the SBA's eligibility criteria are met. As a result, the eligible PPP loans do not have an ACL and are therefore excluded from ACL-related disclosures.

(3) Loans and leases where next payment due is less than 30 days from the report date. The tables exclude PPP loans of $1.6 billion, of which $3.3 million were 30-59 days past due and $33.4 million were 60 days or more past due as of June 30, 2022, and PPP loans of $3.3 billion, of which $6.3 million were 30-59 days past due and $21.8 million were 60 days or more past due as of December 31, 2021. Claims for guarantee payments are submitted to the SBA for eligible PPP loans more than 60 days past due.

The increase in ACL for the three and six months ended June 30, 2022 was primarily attributable to loan growth. Troubled Debt Restructurings At June 30, 2022 and December 31, 2021, there were $16.8 million and $16.5 million, respectively, in loans reported as TDRs. TDRs are reported as impaired loans in the quarter of their restructuring and are evaluated to determine whether they should be placed on non-accrual status. In subsequent quarters, a TDR may be returned to accrual status if it satisfies a minimum performance requirement of six months, however, it will remain classified as impaired. Generally, the Bank requires sustained performance for nine months before returning a TDR to accrual status. Customers had no lease receivables that had been restructured as a TDR as of June 30, 2022 and December 31, 2021, respectively. The following table presents loans modified in a TDR by type of concession for the three and six months ended June 30, 2022 and 2021.

The nature and extent of impairment of TDRs, including those which have experienced a subsequent default, is considered in the determination of an appropriate level of ACL. Credit Quality Indicators The ACL represents management's estimate of expected losses in Customers' loans and leases receivable portfolio, excluding commercial mortgage warehouse loans reported at fair value pursuant to a fair value option election and PPP loans receivable. Multi-family, commercial and industrial, owner occupied commercial real estate, non-owner occupied commercial real estate, and construction loans are rated based on an internally assigned risk rating system which is assigned at the time of loan origination and reviewed on a periodic, or on an “as needed” basis. Residential real estate, manufactured housing and installment loans are evaluated based on the payment activity of the loan. To facilitate the monitoring of credit quality within the multi-family, commercial and industrial, owner occupied commercial real estate, non-owner occupied commercial real estate, and construction loan portfolios, and as an input in the ACL lifetime loss rate model for the commercial and industrial loan portfolio, the Bank utilizes the following categories of risk ratings: pass/satisfactory (includes risk rating 1 through 6), special mention, substandard, doubtful, and loss. The risk rating categories, which are derived from standard regulatory rating definitions, are assigned upon initial approval of credit to borrowers and updated periodically thereafter. Pass ratings, which are assigned to those borrowers who do not have identified potential or well-defined weaknesses and for whom there is a high likelihood of orderly repayment, are updated periodically based on the size and credit characteristics of the borrower. All other categories are updated on a quarterly basis during the month preceding the end of the calendar quarter. While assigning risk ratings involves judgment, the risk-rating process allows management to identify riskier credits in a timely manner and allocate the appropriate resources to manage those loans and leases. The 2021 Form 10-K describes Customers Bancorp’s risk rating grades. Risk ratings are not established for certain consumer loans, including residential real estate, home equity, manufactured housing, and installment loans, mainly because these portfolios consist of a larger number of homogeneous loans with smaller balances. Instead, these portfolios are evaluated for risk mainly based upon aggregate payment history through the monitoring of delinquency levels and trends and are classified as performing and non-performing. The following tables present the credit ratings of loans and leases receivable as of June 30, 2022 and December 31, 2021.

Leases	LEASES Lessee Customers has operating leases for its branches, certain LPOs, and administrative offices, with remaining lease terms ranging between 10 months and 8 years. These operating leases comprise substantially all of Customers' obligations in which Customers is the lessee. These lease agreements typically consist of initial lease terms ranging between 1 and 10 years, with options to renew the leases or extend the term up to 10 years at Customers' sole discretion. Some operating leases include variable lease payments that are based on an index or rate, such as the CPI. Variable lease payments are not included in the liability or ROU asset and are recognized in the period in which the obligation for those payments are incurred. Customers' operating lease agreements do not contain any material residual value guarantees or material restrictive covenants. Pursuant to these agreements, Customers does not have any commitments that would meet the definition of a finance lease. As most of Customers' operating leases do not provide an implicit rate, Customers utilized its incremental borrowing rate when determining the present value of lease payments.

Expected credit losses on direct financing leases and the related estimated residual values are included in the ACL on loans and leases. Leased assets under operating leases are carried at amortized cost net of accumulated depreciation and any impairment charges and are presented in other assets. The depreciation expense of the leased assets is recognized on a straight-line basis over the contractual term of the leases up to the expected residual value. The expected residual value and, accordingly, the monthly depreciation expense, may change throughout the term of the lease. Operating lease rental income for leased assets is recognized in commercial lease income on a straight-line basis over the lease term. Customers periodically reviews its operating leased assets for impairment. An impairment loss is recognized if the carrying amount of the operating leased asset exceeds its fair value and is not recoverable. The carrying amount of operating leased assets is not recoverable if it exceeds the sum of the undiscounted cash flows expected to result from the lease payments and the estimated residual value upon the eventual disposition of the equipment.

Leases	LEASES Lessee Customers has operating leases for its branches, certain LPOs, and administrative offices, with remaining lease terms ranging between 10 months and 8 years. These operating leases comprise substantially all of Customers' obligations in which Customers is the lessee. These lease agreements typically consist of initial lease terms ranging between 1 and 10 years, with options to renew the leases or extend the term up to 10 years at Customers' sole discretion. Some operating leases include variable lease payments that are based on an index or rate, such as the CPI. Variable lease payments are not included in the liability or ROU asset and are recognized in the period in which the obligation for those payments are incurred. Customers' operating lease agreements do not contain any material residual value guarantees or material restrictive covenants. Pursuant to these agreements, Customers does not have any commitments that would meet the definition of a finance lease. As most of Customers' operating leases do not provide an implicit rate, Customers utilized its incremental borrowing rate when determining the present value of lease payments.

Regulatory Capital

Regulatory Capital	Jun. 30, 2022
Regulatory Capital [Abstract]
Regulatory Capital	REGULATORY CAPITAL The Bank and the Bancorp are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet the minimum capital requirements can result in certain mandatory, and possibly additional discretionary, actions by regulators that, if undertaken, could have a direct material effect on Customers' financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Bank and the Bancorp must meet specific capital guidelines that involve quantitative measures of their assets, liabilities and certain off-balance sheet items, as calculated under the regulatory accounting practices. The capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors. Prompt corrective action provisions are not applicable to bank holding companies. In first quarter 2020, U.S federal banking regulatory agencies permitted banking organizations to phase-in, for regulatory capital purposes, the day-one impact of the new CECL accounting rule on retained earnings over a period of three years. As part of its response to the impact of COVID-19, on March 31, 2020, the U.S. federal banking regulatory agencies issued an interim final rule that provided the option to temporarily delay certain effects of CECL on regulatory capital for two years, followed by a three-year transition period. The interim final rule allows banking organizations to delay for two years 100% of the day-one impact of adopting CECL and 25% of the cumulative change in the reported allowance for credit losses since adopting CECL. Customers has elected to adopt the interim final rule, which is reflected in the regulatory capital data presented below. The cumulative CECL capital transition impact as of December 31, 2021 which amounted to $61.6 million will be phased in at 25% per year beginning on January 1, 2022 through December 31, 2024. As of June 30, 2022, our regulatory capital ratios reflected 75%, or $46.2 million, benefit associated with the CECL transition provisions. In April 2020, the U.S. federal banking regulatory agencies issued an interim final rule that permits banks to exclude the impact of participating in the SBA PPP program in their regulatory capital ratios. Specifically, PPP loans are zero percent risk weighted and a bank can exclude all PPP loans pledged as collateral to the PPPLF from its average total consolidated assets for purposes of calculating the Tier 1 capital to average assets ratio (i.e. a leverage ratio). Customers applied this regulatory guidance in the calculation of its regulatory capital ratios presented below. Quantitative measures established by regulation to ensure capital adequacy require the Bank and the Bancorp to maintain minimum amounts and ratios (set forth in the following table) of common equity Tier 1, Tier 1, and total capital to risk-weighted assets, and Tier 1 capital to average assets (as defined in the regulations). At June 30, 2022 and December 31, 2021, the Bank and the Bancorp satisfied all capital requirements to which they were subject. Generally, to comply with the regulatory definition of adequately capitalized, or well capitalized, respectively, or to comply with the Basel III capital requirements, an institution must at least maintain the common equity Tier 1, Tier 1 and total risk-based capital ratios and the Tier 1 leverage ratio in excess of the related minimum ratios as set forth in the following table: Minimum Capital Levels to be Classified as: Actual Adequately Capitalized Well Capitalized Basel III Compliant (dollars in thousands) Amount Ratio Amount Ratio Amount Ratio Amount Ratio As of June 30, 2022: Common equity Tier 1 capital (to risk-weighted assets) Customers Bancorp, Inc. $ 1,383,051 9.690 % $ 642,289 4.500 % N/A N/A $ 999,117 7.000 % Customers Bank $ 1,633,346 11.460 % $ 641,349 4.500 % $ 926,393 6.500 % $ 997,654 7.000 % Tier 1 capital (to risk-weighted assets) Customers Bancorp, Inc. $ 1,520,844 10.655 % $ 856,386 6.000 % N/A N/A $ 1,213,213 8.500 % Customers Bank $ 1,633,346 11.460 % $ 855,132 6.000 % $ 1,140,176 8.000 % $ 1,211,437 8.500 % Total capital (to risk-weighted assets) Customers Bancorp, Inc. $ 1,799,354 12.607 % $ 1,141,848 8.000 % N/A N/A $ 1,498,675 10.500 % Customers Bank $ 1,839,362 12.906 % $ 1,140,176 8.000 % $ 1,425,220 10.000 % $ 1,496,481 10.500 % Tier 1 capital (to average assets) Customers Bancorp, Inc. $ 1,520,844 7.522 % $ 808,706 4.000 % N/A N/A $ 808,706 4.000 % Customers Bank $ 1,633,346 8.087 % $ 807,863 4.000 % $ 1,009,829 5.000 % $ 807,863 4.000 % As of December 31, 2021: Common equity Tier 1 capital (to risk-weighted assets) Customers Bancorp, Inc. $ 1,291,270 9.981 % $ 582,179 4.500 % N/A N/A $ 905,611 7.000 % Customers Bank $ 1,526,583 11.825 % $ 580,943 4.500 % $ 839,140 6.500 % $ 903,689 7.000 % Tier 1 capital (to risk-weighted assets) Customers Bancorp, Inc. $ 1,429,063 11.046 % $ 776,238 6.000 % N/A N/A $ 1,099,671 8.500 % Customers Bank $ 1,526,583 11.825 % $ 774,591 6.000 % $ 1,032,788 8.000 % $ 1,097,337 8.500 % Total capital (to risk-weighted assets) Customers Bancorp, Inc. $ 1,667,395 12.888 % $ 1,034,984 8.000 % N/A N/A $ 1,358,417 10.500 % Customers Bank $ 1,692,512 13.110 % $ 1,032,788 8.000 % $ 1,290,985 10.000 % $ 1,355,534 10.500 % Tier 1 capital (to average assets) Customers Bancorp, Inc. $ 1,429,063 7.413 % $ 771,084 4.000 % N/A N/A $ 771,084 4.000 % Customers Bank $ 1,526,583 7.925 % $ 770,528 4.000 % $ 963,160 5.000 % $ 770,528 4.000 % The Basel III Capital Rules require that we maintain a 2.500% capital conservation buffer with respect to each of common equity Tier 1, Tier 1 and total capital to risk-weighted assets, which provides for capital levels that exceed the minimum risk-based capital adequacy requirements.

Fair Value Disclosures [Abstract]
Disclosures About Fair Value of Financial Instruments	DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS Customers uses fair value measurements to record fair value adjustments to certain assets and liabilities and to disclose the fair value of its financial instruments. ASC 825, Financial Instruments , requires disclosure of the estimated fair value of an entity’s assets and liabilities considered to be financial instruments. For Customers, as for most financial institutions, the majority of its assets and liabilities are considered to be financial instruments. Many of these instruments lack an available trading market as characterized by a willing buyer and a willing seller engaging in an exchange transaction. For fair value disclosure purposes, Customers utilized certain fair value measurement criteria under ASC 820, Fair Value Measurements and Disclosures ("ASC 820"), as explained below. In accordance with ASC 820, the fair value of a financial instrument is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is best determined based upon quoted market prices. However, in many instances, there are no quoted market prices for Customers' various financial instruments. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. Accordingly, the fair value estimates may not be realized in an immediate settlement of the instrument. The fair value guidance provides a consistent definition of fair value, focusing on an exit price in an orderly transaction (that is, not a forced liquidation or distressed sale) between market participants at the measurement date under current market conditions. If there has been a significant decrease in the volume and level of activity for the asset or liability, a change in valuation technique or the use of multiple valuation techniques may be appropriate. In such instances, determining the price at which willing market participants would transact at the measurement date under current market conditions depends on the facts and circumstances and requires the use of significant judgment. The fair value is a reasonable point within the range that is most representative of fair value under current market conditions. The fair value guidance also establishes a fair value hierarchy and describes the following three levels used to classify fair value measurements. Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. Level 2: Quoted prices in markets that are not active, or inputs that are observable either directly or indirectly, for substantially the full term of the asset or liability. Level 3: Prices or valuation techniques that require adjustments to inputs that are both significant to the fair value measurement and unobservable (i.e., supported with little or no market activity). A financial instrument’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. The following methods and assumptions were used to estimate the fair values of Customers' financial instruments as of June 30, 2022 and December 31, 2021: Financial Instruments Recorded at Fair Value on a Recurring Basis Investment securities: The fair values of equity securities with a readily determinable fair value, AFS debt securities and debt securities reported at fair value based on a fair value option election are determined by obtaining quoted market prices on nationally recognized and foreign securities exchanges (Level 1), quoted prices in markets that are not active (Level 2), matrix pricing (Level 2), which is a mathematical technique used widely in the industry to value debt securities without relying exclusively on quoted market prices for the specific securities but rather by relying on the securities’ relationship to other benchmark quoted prices, or internally and externally developed models that use unobservable inputs due to limited or no market activity of the instrument (Level 3). When quoted market prices are not available, Customers employs an independent pricing service that utilizes matrix pricing to calculate fair value. Such fair value measurements consider observable data such as dealer quotes, market spreads, cash flows, yield curves, live trading levels, trade execution data, market consensus prepayments speeds, credit information, and respective terms and conditions for debt instruments. Management maintains procedures to monitor the pricing service's results and has an established process to challenge their valuations, or methodologies, that appear unusual or unexpected. Customers also utilizes internally and externally developed models that use unobservable inputs due to limited or no market activity of the instrument. These models use unobservable inputs that are inherently judgmental and reflect our best estimates of the assumptions a market participant would use to calculate fair value. Certain unobservable inputs in isolation may have either a directionally consistent or opposite impact on the fair value of the instrument for a given change in that input. When multiple inputs are used within the valuation techniques, a change in one input in a certain direction may be offset by an opposite change from another input. These assets are classified as Level 1, 2 or 3 fair values, based upon the lowest level of input that is significant to the fair value measurements. Loans held for sale - Residential mortgage loans (fair value option): Customers generally estimates the fair values of residential mortgage loans held for sale based on commitments on hand from investors within the secondary market for loans with similar characteristics. These assets are classified as Level 2 fair values, based upon the lowest level of input that is significant to the fair value measurements. Loans receivable - Commercial mortgage warehouse loans (fair value option): The fair value of commercial mortgage warehouse loans is the amount of cash initially advanced to fund the mortgage, plus accrued interest and fees, as specified in the respective agreements. The loan is used by mortgage companies as short-term bridge financing between the funding of the mortgage loans and the finalization of the sale of the loans to an investor. Changes in fair value are not generally expected to be recognized because at inception of the transaction the underlying mortgage loans have already been sold to an approved investor. Additionally, the interest rate is variable, and the transaction is short-term, with an average life of under 30 days from purchase to sale. These assets are classified as Level 2 fair values, based upon the lowest level of input that is significant to the fair value measurements. Derivatives (assets and liabilities): The fair values of interest rate swaps, interest rate caps and credit derivatives are determined using models that incorporate readily observable market data into a market standard methodology. This methodology nets the discounted future cash receipts and the discounted expected cash payments. The discounted variable cash receipts and payments are based on expectations of future interest rates derived from observable market interest rate curves. In addition, fair value is adjusted for the effect of nonperformance risk by incorporating credit valuation adjustments for Customers and its counterparties. These assets and liabilities are classified as Level 2 fair values, based upon the lowest level of input that is significant to the fair value measurements. The fair values of the residential mortgage loan commitments are derived from the estimated fair values that can be generated when the underlying mortgage loan is sold in the secondary market. Customers generally uses commitments on hand from third party investors to estimate an exit price and adjusts for the probability of the commitment being exercised based on Customers' internal experience (i.e., pull-through rate). These assets and liabilities are classified as Level 3 fair values, based upon the lowest level of input that is significant to the fair value measurements. Derivative assets and liabilities are presented in "Other assets" and "Accrued interest payable and other liabilities" on the consolidated balance sheet. Financial Instruments Recorded at Fair Value on a Nonrecurring Basis Collateral-dependent loans: Collateral-dependent loans are those loans that are accounted for under ASC 326, Financial Instruments - Credit Losses ("ASC 326"), in which the Bank has measured impairment generally based on the fair value of the loan’s collateral or DCF analysis. Fair value is generally determined based upon independent third-party appraisals of the properties that collateralize the loans, DCF based upon the expected proceeds, sales agreements or letters of intent with third parties. These assets are generally classified as Level 3 fair values, based upon the lowest level of input that is significant to the fair value measurements. The following information should not be interpreted as an estimate of Customers' fair value in its entirety because fair value calculations are only provided for a limited portion of Customers' assets and liabilities. Due to a wide range of valuation techniques and the degree of subjectivity used in making these estimates, comparisons between Customers' disclosures and those of other companies may not be meaningful. The estimated fair values of Customers' financial instruments at June 30, 2022 and December 31, 2021 were as follows.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities	DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES Risk Management Objectives of Using Derivatives Customers is exposed to certain risks arising from both its business operations and economic conditions. Customers manages economic risks, including interest rate, liquidity and credit risk, primarily by managing the amount, sources, and durations of its assets and liabilities. Specifically, Customers enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the values of which are determined by interest rates. Customers’ derivative financial instruments are used to manage differences in the amount, timing, and duration of Customers’ known or expected cash receipts and its known or expected cash payments principally related to certain borrowings and deposits. Customers also has interest-rate derivatives resulting from an accommodation provided to certain qualifying customers, and therefore, they are not used to manage Customers’ interest-rate risk in assets or liabilities. Customers manages a matched book with respect to its derivative instruments used in this customer service in order to minimize its net risk exposure resulting from such transactions. Cash Flow Hedges of Interest-Rate Risk Customers’ objectives in using interest-rate derivatives are to add stability to interest expense and to manage exposure to interest rate movements. To accomplish this objective, Customers primarily uses interest rate swaps as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for Customers making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. The changes in the fair value of derivatives designated and qualifying as cash flow hedges are recorded in AOCI and subsequently reclassified into earnings in the period that the hedged item affects earnings. To date, such derivatives were used to hedge the variable cash flows associated with the forecasted issuances of debt and a certain variable-rate deposit relationship. Customers discontinues cash flow hedge accounting if it is probable the forecasted hedged transactions will not occur in the initially identified time period. At such time, the associated gains and losses deferred in AOCI are reclassified immediately into earnings and any subsequent changes in the fair value of such derivatives are recognized directly in earnings. During the six months ended June 30, 2021, Customers terminated four interest rate derivatives with notional amounts totaling $850 million that were designated as cash flow hedges of interest-rate risk associated with 3-month FHLB advances, and reclassified $25.9 million of the realized losses and accrued interest from AOCI to current earnings because the hedged forecasted transactions were determined to be no longer probable of occurring. Customers hedged its exposure to the variability in future cash flows for a variable-rate deposit, which matured in June 2021. At June 30, 2022 and December 31, 2021, Customers had no interest rate derivative designated as cash flow hedges of interest rate risk. Fair Value Hedges of Benchmark Interest-Rate Risk Customers is exposed to changes in the fair value of certain of its fixed rate AFS debt securities due to changes in the benchmark interest rate. Customers uses interest rate swaps to manage its exposure to changes in fair value on these instruments attributable to changes in the designated benchmark interest rate such as the Fed Funds Effective Swap Rate. Interest rate swaps designated as fair value hedges involve the payment of fixed-rate amounts to a counterparty in exchange for Customers receiving variable-rate payments over the life of the agreements without the exchange of the underlying notional amount. For derivatives designated and that qualify as fair value hedges, the gain or loss on the derivative as well as the offsetting loss or gain on the hedged item attributable to the hedged risk are recognized in interest income. At June 30, 2022, Customers had seven outstanding interest rate derivatives with notional amounts totaling $32.5 million that were designated as fair value hedges of certain AFS debt securities. During the three and six months ended June 30, 2022, Customers terminated seven and nine interest rate derivatives with notional amounts totaling $31.5 million and $48.0 million, respectively, that were designated as fair value hedges together with the sale of hedged AFS debt securities. During the three and six months ended June 30, 2021, Customers terminated one and eight interest rate derivatives with notional amounts totaling $5.0 million and $191.8 million, respectively, that were designated as fair value hedges together with the sale of hedged AFS debt securities. At December 31, 2021, Customers had 16 outstanding interest rate derivatives with notional amounts totaling $80.5 million designated as fair value hedges. As of June 30, 2022, the following amounts were recorded on the consolidated balance sheet related to cumulative basis adjustments for fair value hedges. Amortized Cost Cumulative Amount of Fair Value Hedging Adjustment to Hedged Items (amounts in thousands) June 30, 2022 December 31, 2021 June 30, 2022 December 31, 2021 AFS debt securities $ 32,500 $ 80,500 $ 2,118 $ 1,750 Derivatives Not Designated as Hedging Instruments Customers executes interest rate swaps (typically the loan customers will swap a floating-rate loan for a fixed-rate loan) and interest rate caps with commercial banking customers to facilitate their respective risk management strategies. The customer interest rate swaps and interest rate caps are simultaneously offset by interest rate swaps and interest rate caps that Customers executes with a third party in order to minimize interest-rate risk exposure resulting from such transactions. As the interest rate swaps and interest rate caps associated with this program do not meet the hedge accounting requirements, changes in the fair value of both the customer swaps and caps and the offsetting third-party market swaps and caps are recognized directly in earnings. At June 30, 2022, Customers had 151 interest rate swaps with an aggregate notional amount of $1.4 billion and 12 interest rate caps with an aggregated notional amount of $243.8 million related to this program. At December 31, 2021, Customers had 153 interest rate swaps with an aggregate notional amount of $1.4 billion and 14 interest rate caps with an aggregate notional amount of $264.7 million related to this program. Customers enters into residential mortgage loan commitments in connection with its consumer mortgage banking activities to fund mortgage loans at specified rates and times in the future. These commitments are short-term in nature and generally expire in 30 to 60 days. The residential mortgage loan commitments that relate to the origination of mortgage loans that will be held for sale are considered derivative instruments under applicable accounting guidance and are reported at fair value, with changes in fair value recorded directly in earnings. At June 30, 2022 and December 31, 2021, Customers had an aggregate notional amount of residential mortgage loan commitments of $5.0 million and $8.2 million, respectively. Customers has also purchased and sold credit derivatives to either hedge or participate in the performance risk associated with some of its counterparties. These derivatives are not designated as hedging instruments and are reported at fair value, with changes in fair value recorded directly in earnings. At June 30, 2022 and December 31, 2021, Customers had an aggregate notional amount of credit derivatives of $143.8 million and $129.9 million, respectively.

The credit risk associated with derivatives executed with customers is the same as that involved in extending the related loans and is subject to the same standard credit policies. To mitigate the credit-risk exposure to major derivative dealer counterparties, Customers only enters into agreements with those counterparties that maintain credit ratings of high quality or with central clearing parties. Agreements with major derivative dealer counterparties contain provisions whereby default on any of Customers' indebtedness would be considered a default on its derivative obligations. Customers also has entered into agreements that contain provisions under which the counterparty could require Customers to settle its obligations if Customers fails to maintain its status as a well/adequately capitalized institution. As of June 30, 2022, the fair value of derivatives in a net asset position (which includes accrued interest but excludes any adjustment for nonperformance-risk) related to these agreements was $14.4 million. In addition, Customers, which has collateral posting thresholds with certain of these counterparties, had received $15.9 million of cash as collateral at June 30, 2022. Customers records cash posted or received as collateral with these counterparties, except with a central clearing entity, as a reduction or an increase in the outstanding balance of cash and cash equivalents and an increase in the balance of other assets or other liabilities. Disclosures about Offsetting Assets and Liabilities The following tables present derivative instruments that are subject to enforceable master netting arrangements. Customers' interest rate swaps and interest rate caps with institutional counterparties are subject to master netting arrangements and are included in the tables below. Interest rate swaps and interest rate caps with commercial banking customers and residential mortgage loan commitments are not subject to master netting arrangements and are excluded from the tables below.

Management does not believe there are any such matters that will have a material effect on the consolidated financial statements that are not currently accrued for. However, in light of the uncertainties inherent in these matters, it is possible that the ultimate resolution may have a material adverse effect on Customers’ results of operations for a particular period, and future changes in circumstances or additional information could result in accruals or resolution in excess of established accruals, which could adversely affect Customers’ results of operations, potentially materially. Specialty’s Café Bakery, Inc. Matter On May 27, 2020, the appointed Chapter 7 Trustee for Specialty’s Café Bakery, Inc. (“Debtor”) filed a voluntary petition for relief under Chapter 7 of the Bankruptcy Code in the United States Bankruptcy Court for the Central District of California. On October 28, 2020, the Trustee, as plaintiff, filed her amended adversary complaint (“Adversary Complaint”) against the Bank and the SBA seeking to avoid and recover for the benefit of the Debtor’s estate and its creditors the payment made by the Debtor to the Bank in the amount of $8.1 million in satisfaction of a PPP loan made by the Bank to the Debtor (the “PPP Loan Payment”). The Trustee sought to avoid and recover the entire PPP Loan Payment from the Bank under the authority provided in 11 U.S.C. §547 and §550, which together permit a trustee of a bankruptcy debtor to avoid and recover, for a more equitable distribution among all creditors, certain transfers made within ninety (90) days before the filing of the bankruptcy petition. On December 2, 2021, the Bank filed a motion for summary judgement, arguing that the Trustee had failed to establish the elements under 11 U.S.C. §547 necessary to recover the PPP Loan Payment and other affirmative defenses to any such recovery. On February 2, 2022, the United States Bankruptcy Court for the Central District of California granted the Bank’s motion for summary judgment, finding that the PPP Loan Payment was not recoverable by the Trustee. The Trustee has elected not to appeal this decision and, on February 23, 2022, the case against the Bank was closed by the United States Bankruptcy Court for the Central District of California.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The interim unaudited consolidated financial statements have been prepared in conformity with U.S. GAAP and pursuant to the rules and regulations of the SEC. These interim unaudited consolidated financial statements reflect all normal and recurring adjustments that are, in the opinion of management, necessary to present a fair statement of the financial position and the results of operations and cash flows of Customers Bancorp and subsidiaries for the interim periods presented. Certain information and footnote disclosures normally included in the annual consolidated financial statements have been omitted from these interim unaudited consolidated financial statements as permitted by SEC rules and regulations. The December 31, 2021 consolidated balance sheet presented in this report has been derived from Customers Bancorp’s audited 2021 consolidated financial statements. Management believes that the disclosures are adequate to present fairly the consolidated financial statements as of the dates and for the periods presented. These interim unaudited consolidated financial statements should be read in conjunction with the 2021 consolidated financial statements of Customers Bancorp and subsidiaries included in Customers' Annual Report on Form 10-K for the year ended December 31, 2021 filed with the SEC on February 28, 2022 (the "2021 Form 10-K"). The 2021 Form 10-K describes Customers Bancorp’s significant accounting policies. There have been no material changes to Customers Bancorp's significant accounting policies noted above for the three and six months ended June 30, 2022.
Recently Issued Accounting Standards and Accounting Standards Issued But Not Yet Adopted	Recently Issued Accounting Standards Presented below are recently issued accounting standards that the FASB has issued but are not yet effective. Accounting Standards Issued But Not Yet Adopted Standard Summary of Guidance Effects on Financial Statements ASU 2022-02, Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures Issued March 2022 • Eliminates the accounting guidance for TDRs by creditors, and applies the loan refinancing and restructuring guidance when a borrower is experiencing financial difficulty to determine whether a modification results in a new loan or a continuation of an existing loan. • Provides enhanced disclosure requirements for certain loan refinancing and restructurings and disclosure of current-period gross write-offs by year of origination for financing receivables and net investments in leases within the scope of ASC 326. • Effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Early adoption is permitted, including adoption in any interim period, provided the amendments are adopted as of the beginning of the fiscal year that includes the interim period of adoption. Early adoption is permitted separately for the amendments to TDRs and vintage disclosures. • TDR and vintage disclosures are to be adopted prospectively. An entity may adopt TDR recognition and measurement guidance prospectively or elect to use a modified retrospective transition method, with a cumulative effect adjustment to retained earnings at the beginning of the period of adoption. • Customers expects this guidance will result in additional disclosures related to gross write-offs by vintage year and expansive disclosures for certain loan modifications to borrowers experiencing financial difficulty.
Fair Value Measurement	Customers uses fair value measurements to record fair value adjustments to certain assets and liabilities and to disclose the fair value of its financial instruments. ASC 825, Financial Instruments , requires disclosure of the estimated fair value of an entity’s assets and liabilities considered to be financial instruments. For Customers, as for most financial institutions, the majority of its assets and liabilities are considered to be financial instruments. Many of these instruments lack an available trading market as characterized by a willing buyer and a willing seller engaging in an exchange transaction. For fair value disclosure purposes, Customers utilized certain fair value measurement criteria under ASC 820, Fair Value Measurements and Disclosures ("ASC 820"), as explained below. In accordance with ASC 820, the fair value of a financial instrument is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is best determined based upon quoted market prices. However, in many instances, there are no quoted market prices for Customers' various financial instruments. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. Accordingly, the fair value estimates may not be realized in an immediate settlement of the instrument. The fair value guidance provides a consistent definition of fair value, focusing on an exit price in an orderly transaction (that is, not a forced liquidation or distressed sale) between market participants at the measurement date under current market conditions. If there has been a significant decrease in the volume and level of activity for the asset or liability, a change in valuation technique or the use of multiple valuation techniques may be appropriate. In such instances, determining the price at which willing market participants would transact at the measurement date under current market conditions depends on the facts and circumstances and requires the use of significant judgment. The fair value is a reasonable point within the range that is most representative of fair value under current market conditions. The fair value guidance also establishes a fair value hierarchy and describes the following three levels used to classify fair value measurements. Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. Level 2: Quoted prices in markets that are not active, or inputs that are observable either directly or indirectly, for substantially the full term of the asset or liability. Level 3: Prices or valuation techniques that require adjustments to inputs that are both significant to the fair value measurement and unobservable (i.e., supported with little or no market activity). A financial instrument’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement.
Derivatives	Risk Management Objectives of Using Derivatives Customers is exposed to certain risks arising from both its business operations and economic conditions. Customers manages economic risks, including interest rate, liquidity and credit risk, primarily by managing the amount, sources, and durations of its assets and liabilities. Specifically, Customers enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the values of which are determined by interest rates. Customers’ derivative financial instruments are used to manage differences in the amount, timing, and duration of Customers’ known or expected cash receipts and its known or expected cash payments principally related to certain borrowings and deposits. Customers also has interest-rate derivatives resulting from an accommodation provided to certain qualifying customers, and therefore, they are not used to manage Customers’ interest-rate risk in assets or liabilities. Customers manages a matched book with respect to its derivative instruments used in this customer service in order to minimize its net risk exposure resulting from such transactions. Cash Flow Hedges of Interest-Rate Risk Customers’ objectives in using interest-rate derivatives are to add stability to interest expense and to manage exposure to interest rate movements. To accomplish this objective, Customers primarily uses interest rate swaps as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for Customers making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. The changes in the fair value of derivatives designated and qualifying as cash flow hedges are recorded in AOCI and subsequently reclassified into earnings in the period that the hedged item affects earnings. To date, such derivatives were used to hedge the variable cash flows associated with the forecasted issuances of debt and a certain variable-rate deposit relationship.
