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, 2019 consolidated balance sheet presented in this report has been derived from Customers Bancorp’s audited 2019 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 2019 consolidated financial statements of Customers Bancorp and subsidiaries included in Customers' Annual Report on Form 10-K for the year ended December 31, 2019 filed with the SEC on March 2, 2020 (the "2019 Form 10-K"). The 2019 Form 10-K describes Customers Bancorp’s significant accounting policies, which include its policies on Principles of Consolidation; Cash and Cash Equivalents and Statements of Cash Flows; Restrictions on Cash and Amounts due from Banks; Business Combinations; Investment Securities; Loan Accounting Framework; Loans Held for Sale and Loans at Fair Value; Loans Receivable - Mortgage Warehouse, at Fair Value; Loans and Leases Receivable; Purchased Loans; ALLL; Goodwill and Other Intangible Assets; FHLB, Federal Reserve Bank, and Other Restricted Stock; OREO; BOLI; Bank Premises and Equipment; Lessor Operating Leases; Treasury Stock; Income Taxes; Share-Based Compensation; Transfer of Financial Assets; Segment Information; Derivative Instruments and Hedging; Comprehensive Income (Loss); EPS; Loss Contingencies; and Collaborative Arrangements. There have been no material changes to Customers Bancorp's significant accounting policies noted above for the three months ended March 31, 2020, except for the adoption of ASU 2016-13 Financial Instruments - Credit Losses ("ASC 326"): Measurement of Credit Losses on Financial Instruments, which is discussed below in Adoption of New Accounting Standard, and replaces our prior ALLL policy. New Accounting Standards Presented below are recently issued accounting standards that Customers has adopted as well as those that the FASB has issued but are not yet effective. Accounting Standards Adopted in 2020 Allowance for Credit Losses On January 1, 2020, Customers adopted ASC 326, which replaced the incurred loss methodology with an expected loss methodology that is referred to as CECL methodology. The measurement of expected credit losses under the CECL methodology is applicable to financial assets measured at amortized cost, including loan receivables and net investments in leases recognized by Customers as a lessor in accordance with ASC 842. CECL also applies to off-balance sheet credit exposures not accounted for as insurance, such as loan commitments, standby letters of credit, financial guarantees, and other similar instruments. ASC 326 also made changes to the accounting for AFS debt securities, which now requires credit losses to be presented as an allowance, rather than as a write-down on AFS debt securities that management does not intend to sell or believes that it is more likely than not they will not be required to sell. Customers adopted ASC 326 using the modified retrospective method for all financial assets measured at amortized cost, net investments in leases, and off-balance sheet credit exposures. Results for reporting periods beginning after December 31, 2019 are presented under ASC 326, while prior period amounts continue to be reported in accordance with previously applicable GAAP. Customers recorded a net decrease to retained earnings of $61.5 million, net of deferred taxes of $21.5 million, as of January 1, 2020 for the cumulative effect of adopting ASC 326. Customers adopted ASC 326 using the prospective transition approach for PCD financial assets that were previously classified as PCI and accounted for under ASC 310-30. In accordance with the standard, Customers did not reassess whether PCI assets met the criteria of PCD assets as of the date of adoption. On January 1, 2020, the amortized cost basis of the PCD assets were adjusted to reflect the addition of $0.2 million of the allowance for credit losses on PCD loans and leases. The remaining noncredit discount of $0.3 million, based on the adjusted amortized cost basis, will be accreted into interest income at the effective interest rate as of January 1, 2020.

Loans and leases deemed to be uncollectible are charged against the allowance for credit losses on loans and leases, and subsequent recoveries, if any, are credited to the allowance for credit losses on loans and leases. Expected recoveries do not exceed the aggregate of amounts previously charged-off and expected to be charged-off. Changes to the allowance for credit losses on loans and leases are recorded through the provision for credit losses on loans and leases. The allowance for credit losses on loans and leases is maintained at a level considered appropriate to absorb expected credit losses over the expected life of the portfolio as of the reporting date. The allowance for credit losses on loans and leases is measured on a collective (pool) basis when similar risk characteristics exist. Customers' loan portfolio segments include commercial and consumer. Each of these two loan portfolio segments is comprised of multiple loan classes. Loan classes are characterized by similarities in loan type, collateral type, risk attributes and the manner in which credit risk is assessed and monitored. The commercial segment is composed of multi-family, commercial and industrial, commercial real estate owner occupied, commercial real estate non-owner occupied and construction loan classes. The consumer segment is composed of residential real estate, manufactured housing and other consumer. Loans that do not share risk characteristics are evaluated on an individual basis. Loans evaluated individually are not also included in the collective evaluation. For individually assessed loans, see related details in the Individually Assessed Loans section below. The allowance for credit losses on collectively assessed loans and leases is measured over the expected life of the loan or lease using lifetime loss rate models which consider historical loan performance, loan or borrower attributes and forecasts of future economic conditions in addition to information about past events and current conditions. Significant loan/borrower attributes utilized in the models include origination date, maturity date, collateral property type, internal risk rating, delinquency status, borrower state and FICO score at origination. Customers uses external sources in the creation of its forecasts, including current economic conditions and forecasts for macroeconomic variables over its reasonable and supportable forecast period (e.g., GDP growth rate, unemployment rate, BBB spread, commercial real estate and home price index). After the reasonable and supportable forecast period, which ranges from two to five years, the models revert the forecasted macroeconomic variables to their historical long-term trends, without specific predictions for the economy, over the expected life of the pool. The lifetime loss rate models also incorporate prepayment assumptions into estimated lifetime loss rates. Customers runs the CECL impairment models on a quarterly basis and qualitatively adjusts model results for risk factors that are not considered within the models but which are relevant in assessing the expected credit losses within the loan and lease pools. Management generally considers the following qualitative factors: • Volume and severity of past-due loans, non-accrual loans and classified loans; • Lending policies and procedures, including underwriting standards and historically based loss/collection, charge-off and recovery practices; • Nature and volume of the portfolio; • Existence and effect of any credit concentrations and changes in the level of such concentrations; • Risk ratings; • The value of the underlying collateral for loans that are not collateral dependent; • Changes in the quality of the loan review system; • Experience, ability and depth of lending management and staff; • Other external factors, such as changes in legal, regulatory or competitive environment; and • Model and data limitations. Customers has elected to not estimate an allowance for credit losses on accrued interest receivable, as it already has a policy in place to reverse or write-off accrued interest, through interest income, in a timely manner. Accrued interest receivable is presented as part of other assets in the consolidated balance sheet. Purchased Credit Deteriorated (“PCD”) Loans and Leases PCD assets are acquired individual loans and leases (or acquired groups of loans and leases with similar risk characteristics) that, as of the date of acquisition, have experienced a more-than-insignificant deterioration in credit quality since origination, as determined by an acquirer’s assessment. PCD loans and leases are recorded at their purchase price plus the allowance for credit losses expected at the time of acquisition, or “gross up” of the amortized cost basis. The January 1, 2020 transition adjustment discussed above was established for these loans and leases without affecting the income statement or retained earnings. Changes in the current estimate of the allowance for credit losses after acquisition from the estimated allowance previously recorded are reported in the income statement as provision for credit losses expense or reversal of provision for credit losses in subsequent periods as they arise. Purchased loans or leases that do not qualify as PCD assets are accounted for similar to originated assets, whereby an allowance for credit losses is recognized with a corresponding increase to the income statement provision for credit losses. Evidence that purchased loans and leases, measured at amortized cost, have more-than-insignificant deterioration in credit quality since origination and, therefore meet the PCD definition, may include loans and leases that are past-due, in non-accrual status, poor borrower credit score, recent loan-to-value percentages and other standard indicators (i.e., TDR, charge-offs and bankruptcy). Allowance for Credit Losses on Lending-Related Commitments Customers estimates expected credit losses over the contractual period in which it is exposed to credit risk on contractual obligations to extend credit, unless the obligation is unconditionally cancellable by Customers. The allowance for credit losses on lending-related commitments is recorded in accrued interest payable and other liabilities in the consolidated balance sheet and is recorded as a provision for credit losses within other non-interest expense in the consolidated income statement. The estimate includes consideration of the likelihood that funding will occur and an estimate of expected credit losses on commitments expected to be funded over their estimated lives. Customers estimates the expected credit losses for undrawn commitments using a usage given default calculation. The lifetime loss rates for off-balance sheet credit exposures are calculated in the same manner as on-balance sheet credit exposures, using the same models and economic forecasts, adjusted for the estimated likelihood that funding will occur. Individually Assessed Loans and Leases ASC 326 provides that a loan or lease is measured individually if it does not share similar risk characteristics with other financial assets. For Customers, loans and leases which are identified to be individually assessed under CECL typically would have been evaluated individually as impaired loans using accounting guidance in effect in periods prior to the adoption of CECL and include troubled debt restructurings (TDRs) and collateral dependent loans. TDRs A loan for which the terms have been modified resulting in a concession, and for which the borrower is experiencing financial difficulties is considered to be a TDR. The allowance for credit loss on a TDR is measured using the same method as all other loans held for investment, except in cases when the value of a concession cannot be measured using a method other than the discounted cash flow (“DCF”) method. When the value of a concession is measured using the DCF method, the allowance for credit loss is determined by discounting the expected future cash flows at the original effective interest rate of the loan. Collateral Dependent Loans Customers considers a loan to be collateral dependent when foreclosure of the underlying collateral is probable. Customers has also elected to apply the practical expedient to measure expected credit losses of a collateral dependent asset using the fair value of the collateral, less any estimated costs to sell, when foreclosure is not probable but repayment of the loan is expected to be provided substantially through the operation or sale of the collateral, and the borrower is experiencing financial difficulty. Allowance for Credit Losses on Available for Sale Securities For AFS debt securities in an unrealized loss position, Customers first assesses whether it intends to sell, or it is more likely than not that it will be required to sell the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the security’s amortized cost basis is written down to fair value through income. For AFS debt securities that do not meet the aforementioned criteria, Customers evaluates whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, management considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency, and adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses on AFS securities is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost basis. Any impairment that has not been recorded through an allowance for credit losses on AFS securities is recognized in other comprehensive income. Changes in the allowance for credit losses on AFS securities are recorded as provision, or reversal of provision for credit losses on AFS securities in other non-interest income within the consolidated income statement. Losses are charged against the allowance for credit losses on AFS securities when management believes the uncollectibility of an AFS security is confirmed or when either of the criteria regarding intent or requirement to sell is met. Accrued interest receivable on AFS debt securities totaled $4.7 million at March 31, 2020 and is excluded from the estimate of credit losses.

(2) Includes both taxable and non-taxable municipal securities. (3) Includes corporate securities issued by domestic bank holding companies. (4) Reported at fair value with fair value changes recorded in non-interest income based on a fair value option election. (5) Includes equity securities issued by a foreign entity. On June 28, 2019, Customers obtained ownership of certain interest-only GNMA securities that served as the primary collateral for loans made to one commercial mortgage warehouse customer through a Uniform Commercial Code private sale transaction. In connection with the acquisition of the interest-only GNMA securities, Customers recognized a pre-tax loss of $7.5 million for the three months ended June 30, 2019 for the shortfall in the fair value of the interest-only GNMA securities compared to its credit exposure to this commercial mortgage warehouse customer. Upon acquisition, Customers elected the fair value option for these interest-only GNMA securities. The fair value of these securities at March 31, 2020 was $15.3 million. During the three months ended March 31, 2020 and 2019, Customers recognized unrealized losses of $1.4 million and unrealized gains of $2 thousand, respectively, on its equity securities. These unrealized gains and losses are reported as unrealized gain (loss) on investment securities within non-interest income on the consolidated statements of income. For the three months ended March 31, 2020, realized gains from sales of available-for-sale securities were $4.0 million. Proceeds from these sales were received in April 2020. There were no sales during the three months ended March 31, 2019. These gains (losses) were determined using the specific identification method and were reported as gain (loss) on sale of investment securities within non-interest income on the consolidated statements of income. The following table shows debt securities by stated maturity. Debt securities backed by mortgages and interest-only GNMA securities 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: March 31, 2020 (amounts in thousands) Amortized Fair Due in one year or less $ 11,885 $ 11,885 Due after one year through five years 57,611 57,723 Due after five years through ten years 282,528 275,182 Due after ten years 19,160 19,231 Agency-guaranteed residential mortgage-backed securities 159,416 172,814 Agency-guaranteed collateralized mortgage obligations 153,952 153,952 Collateralized mortgage obligations 5,566 5,566 Interest-only classes of agency-guaranteed home equity conversion mortgage-backed securities — 15,276 Total debt securities $ 690,118 $ 711,629 Gross unrealized losses and fair value of Customers' available for sale debt securities aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position at March 31, 2020 were as follows: March 31, 2020 Less Than 12 Months 12 Months or More Total (amounts in thousands) Fair Value Unrealized Losses Fair Value Unrealized Losses Fair Value Unrealized Losses Available for sale debt securities: Corporate notes 249,946 8,634 — — 249,946 8,634 Total $ 249,946 $ 8,634 $ — $ — $ 249,946 $ 8,634 At March 31, 2020, there were 13 available for sale debt securities with unrealized losses in the less-than-twelve-month category and no available for sale debt securities with unrealized losses in the twelve-month-or-more category. The unrealized losses on the corporate notes relate to securities with no company specific concentration. The unrealized losses were principally due to changes in market interest rates that resulted in a negative impact on the respective notes' fair value. All amounts related to the corporate notes are expected to be recovered when market prices recover or at maturity. Customers does not intend to sell these securities, and it is not more likely than not that Customers will be required to sell the securities before recovery of the amortized cost basis. At December 31, 2019, there were no available for sale debt securities in an unrealized loss position. At March 31, 2020 and December 31, 2019, Customers Bank had pledged investment securities aggregating $20.0 million and $20.4 million in fair value, respectively, as collateral against its borrowings primarily with an unused line of credit with another financial institution. These counterparties do not have the ability to sell or repledge these securities. At March 31, 2020 and December 31, 2019, no securities holding of any one issuer, other than the U.S. Government and its agencies, amounted to greater than 10% of shareholders' equity.

(2) Includes deferred (fees) costs and unamortized (discounts) premiums, net of $3.2 million and $2.1 million at March 31, 2020 and December 31, 2019, 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 $36.3 million and $34.8 million at March 31, 2020 and December 31, 2019, respectively, and is presented in accrued interest receivable in the consolidated balance sheet. At March 31, 2020, there were $56.5 million of individually evaluated loans that were collateral-dependent. 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. There were no significant changes in collateral values during the three months ended March 31, 2020. Subsequent to March 31, 2020, Customers decided to sell a commercial real estate loan collateralized by a Class A office building in northern New Jersey. At March 31, 2020, this collateral dependent loan has been charged down to its estimated fair value of $19.1 million. 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 March 31, 2020 and December 31, 2019, 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 and leases receivable: The following tables summarize loans and leases receivable by loan and lease type and performance status as of March 31, 2020 and December 31, 2019: March 31, 2020 (amounts in thousands) 30-59 Days past due 60-89 Days past due 90 Days or more past due Total past due Loans and leases not past due (2) Total loans and leases (3) Multi-family $ 2,378 $ — $ 4,021 $ 6,399 $ 1,615,234 $ 1,621,633 Commercial and industrial 1,332 659 10,182 12,173 2,060,779 2,072,952 Commercial real estate owner occupied 4,391 971 2,740 8,102 535,843 543,945 Commercial real estate non-owner occupied 30,723 — 21,470 52,193 1,200,633 1,252,826 Construction — — — — 115,448 115,448 Residential real estate 5,253 68 6,248 11,569 350,478 362,047 Manufactured housing (5) 2,138 962 5,089 8,189 61,051 69,240 Other consumer 6,502 3,725 2,527 12,754 1,302,417 1,315,171 Total $ 52,717 $ 6,385 $ 52,277 $ 111,379 $ 7,241,883 $ 7,353,262 December 31, 2019 (amounts in thousands) 30-89 Days past due (1) 90 Days or more past due (1) Total past due (1) Non-accrual Current (2) Purchased-credit-impaired loans (4) Total loans and leases (5) Multi-family $ 2,133 — $ 2,133 $ 4,117 $ 1,901,336 $ 1,688 $ 1,909,274 Commercial and industrial 2,395 — 2,395 4,531 1,882,700 354 1,889,980 Commercial real estate owner occupied 5,388 — 5,388 1,963 537,992 6,664 552,007 Commercial real estate non-owner occupied 8,034 — 8,034 76 1,211,892 3,527 1,223,529 Construction — — — — 118,418 — 118,418 Residential real estate 5,924 — 5,924 6,128 359,491 3,471 375,014 Manufactured housing 3,699 1,794 5,493 1,655 61,649 1,601 70,398 Other consumer 5,756 $ — 5,756 1,551 1,170,793 183 1,178,283 Total $ 33,329 $ 1,794 $ 35,123 $ 20,021 $ 7,244,271 $ 17,488 $ 7,316,903 (1) Includes past due loans and leases that are accruing interest because collection is considered probable. (2) Loans and leases where next payment due is less than 30 days from the report date. (3) Includes purchased credit deteriorated loans of $16.6 million at March 31, 2020. (4) Purchased-credit-impaired loans aggregated into a pool are accounted for as a single asset with a single composite interest rate and an aggregate expectation of cash flows, and the past due status of the pools, or that of the individual loans within the pools, is not meaningful. Due to the credit impaired nature of the loans, the loans are recorded at a discount reflecting estimated future cash flows and the Bank recognizes interest income on each pool of loans reflecting the estimated yield and passage of time. Such loans are considered to be performing. Purchased-credit-impaired loans that are not in pools accrete interest when the timing and amount of their expected cash flows are reasonably estimable, and are reported as performing loans. (5) Amounts exclude deferred costs and fees and unamortized premiums and discounts. As of both March 31, 2020 and December 31, 2019, the Bank had $0.1 million and $0.2 million, respectively, of residential real estate held in OREO. As of both March 31, 2020 and December 31, 2019, the Bank had initiated foreclosure proceedings on $0.9 million, respectively, in loans secured by residential real estate.

Interest income of $0.2 million and $0.2 million was recognized on nonaccrual loans for the three months ended March 31, 2020 and 2019, respectively. PCD loans are considered to be performing and are not included in the table above. Allowance for credit losses on loans and leases The changes in the allowance for credit losses on loans and leases for the three months ended March 31, 2020 and 2019, is presented in the tables below.

The increase resulted primarily from the impact of reserve build for the COVID-19 pandemic, an increase in net charge-offs, mostly attributed to the commercial real estate non-owner occupied and other consumer portfolios, and portfolio growth. Commercial real estate non-owner occupied charge-offs is attributable to one collateral dependent loan. Other consumer charge-offs is attributable to delinquencies and defaults of originated and purchased unsecured consumer loans through arrangements with fintech companies and other market place lenders. Troubled Debt Restructurings At March 31, 2020 and December 31, 2019, there were $13.5 million and $13.3 million, respectively, in loans reported as TDRs. TDRs are reported as impaired loans in the calendar year of their restructuring and are evaluated to determine whether they should be placed on non-accrual status. In subsequent years, 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 March 31, 2020 and December 31, 2019, respectively. The CARES Act and certain regulatory agencies recently issued guidance stating certain loan modifications to borrowers experiencing financial distress as a result of the economic impacts created by COVID-19 may not be required to be treated as TDRs under U.S GAAP. For COVID-19 related loan modifications which occurred in March 2020, and met the loan modification criteria under either the CARES Act or the criteria specified by the regulatory agencies, Customers elected to suspend TDR accounting for such loan modifications. The following table presents loans modified in a TDR by type of concession for the three months ended March 31, 2020 and 2019. There were no modifications that involved forgiveness of debt for the three months ended March 31, 2020 and 2019. Three Months Ended March 31, 2020 2019 (dollars in thousands) Number of loans Recorded investment Number of loans Recorded investment Extensions of maturity 4 $ 245 2 $ 514 Interest-rate reductions 12 530 10 385 Total 16 $ 775 12 $ 899 As of March 31, 2020, there were no commitments to lend additional funds to debtors whose loans have been modified in TDRs. As of December 31, 2019, there were no commitments to lend additional funds to debtors whose loans have been modified in TDRs. The following table presents, by loan type, the number of loans modified in TDRs and the related recorded investment, for which there was a payment default within twelve months following the modification: March 31, 2020 March 31, 2019 (dollars in thousands) Number of loans Recorded investment Number of loans Recorded investment Manufactured housing — $ — 5 $ 137 Commercial and industrial — — 1 431 Commercial real estate owner occupied 1 8 — — Residential real estate 5 684 — — Total loans 6 $ 692 6 $ 568 Loans modified in TDRs are evaluated for impairment. 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. Purchased Credit-Deteriorated Loans Customers adopted ASC 326 using the prospective transition approach for financial assets purchased with credit deterioration that were previously classified as PCI and accounted for under ASC 310-30. In accordance with the standard, Customers did not reassess whether PCI assets met the criteria of PCD assets as of the date of adoption. On January 1, 2020, the amortized cost basis of the PCD assets were adjusted to reflect the addition of $0.2 million of the allowance for credit losses on PCD loans and leases. The remaining noncredit discount of $0.3 million, based on the adjusted amortized cost basis, will be accreted into interest income at the effective interest rate as of January 1, 2020. As of March 31, 2020, the amortized cost basis of PCD assets amounted to $16.6 million. Credit Quality Indicators The ACL represents management's estimate of probable losses in Customers' loans and leases receivable portfolio, excluding commercial mortgage warehouse loans reported at fair value pursuant to a fair value option election. 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 loans, manufactured housing and other consumer 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 C&I 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/satisfactory 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 2019 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 March 31, 2020 and December 31, 2019.

Leases [Abstract]
Leases	LEASES Lessee Customers has operating leases for its branches, LPOs, and administrative offices, with remaining lease terms ranging between 1 month and 7 years. These operating leases comprise substantially all of Customers' obligations in which Customers is the lessee. Most lease agreements consist of initial lease terms ranging between 1 and 5 years, with options to renew the leases or extend the term up to 15 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 right of use 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 based on the information available at either the adoption of ASC 842 or the commencement date of the lease, whichever was later, when determining the present value of lease payments. The following table summarizes operating lease ROU assets and operating lease liabilities and their corresponding balance sheet location: (amounts in thousands) Classification March 31, 2020 December 31, 2019 ASSETS Operating lease ROU assets Other assets $ 19,323 $ 20,232 LIABILITIES Operating lease liabilities Other liabilities $ 20,483 $ 21,358 The following table summarizes operating lease cost and its corresponding income statement location for the periods presented: Three Months Ended March 31, (amounts in thousands) Classification 2020 2019 Operating lease cost (1) Occupancy expenses $ 1,480 $ 1,469 (1) There were no variable lease costs for the three months ended March 31, 2020 and 2019, and sublease income for operating leases is immaterial.

Customers has legally binding minimum lease payments of $2.3 million for leases signed but not yet commenced as of March 31, 2020. Cash paid pursuant to operating lease liability was $1.5 million and $1.4 million for the three months ended March 31, 2020 and 2019, respectively, and is reported as cash flows used in operating activities in the statement of cash flows. The following table summarizes the weighted average remaining lease term and discount rate for Customers' operating leases at March 31, 2020 and December 31, 2019: (amounts in thousands) March 31, 2020 December 31, 2019 Weighted average remaining lease term (years) Operating leases 4.9 years 5.0 years Weighted average discount rate Operating leases 2.89 % 2.90 % Equipment Lessor CCF is a wholly-owned subsidiary of Customers Bank and is referred to as the Equipment Finance Group. CCF is primarily focused on originating equipment operating and direct finance equipment leases for a broad range of asset classes. It services vendors, dealers, independent finance companies, bank-owned leasing companies and strategic direct customers in the plastics, packaging, machine tool, construction, transportation and franchise markets. Lease terms typically range from 24 months to 120 months. CCF offers the following lease products: Capital Lease, Purchase Upon Termination, TRAC, Split-TRAC, and FMV. Direct finance equipment leases are included in commercial and industrial loans and leases receivable. The estimated residual values for direct finance and operating leases are established by utilizing internally developed analyses, external studies, and/or third-party appraisals to establish a residual position. For the direct finance leases, only for a Split-TRAC is there a residual risk and the unguaranteed portions are typically nominal. Expected credit losses on direct financing leases and the related estimated residual values are included in the allowance for credit losses 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, LPOs, and administrative offices, with remaining lease terms ranging between 1 month and 7 years. These operating leases comprise substantially all of Customers' obligations in which Customers is the lessee. Most lease agreements consist of initial lease terms ranging between 1 and 5 years, with options to renew the leases or extend the term up to 15 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 right of use 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 based on the information available at either the adoption of ASC 842 or the commencement date of the lease, whichever was later, when determining the present value of lease payments.

Regulatory Capital

Regulatory Capital	3 Months Ended

Banking and Thrift [Abstract]
Regulatory Capital	REGULATORY CAPITALThe 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. 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 March 31, 2020 and December 31, 2019, 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 (amounts in thousands) Amount Ratio Amount Ratio Amount Ratio Amount Ratio As of March 31, 2020: Common equity Tier 1 capital (to risk-weighted assets) Customers Bancorp, Inc. $ 827,884 7.560 % $ 492,760 4.500 % N/A N/A $ 766,515 7.000 % Customers Bank $ 1,158,308 10.599 % $ 491,793 4.500 % $ 710,368 6.500 % $ 765,011 7.000 % Tier 1 capital (to risk-weighted assets) Customers Bancorp, Inc. $ 1,045,355 9.546 % $ 657,013 6.000 % N/A N/A $ 930,768 8.500 % Customers Bank $ 1,158,308 10.599 % $ 655,724 6.000 % $ 874,298 8.000 % $ 928,942 8.500 % Total capital (to risk-weighted assets) Customers Bancorp, Inc. $ 1,277,340 11.665 % $ 876,017 8.000 % N/A N/A $ 1,149,773 10.500 % Customers Bank $ 1,334,108 12.207 % $ 874,298 8.000 % $ 1,092,873 10.000 % $ 1,147,517 10.500 % Tier 1 capital (to average assets) Customers Bancorp, Inc. $ 1,045,355 9.011 % $ 464,045 4.000 % N/A N/A $ 464,045 4.000 % Customers Bank $ 1,158,308 9.992 % $ 463,680 4.000 % $ 579,600 5.000 % $ 463,680 4.000 % As of December 31, 2019: Common equity Tier 1 capital (to risk-weighted assets) Customers Bancorp, Inc. $ 821,810 7.984 % $ 463,211 4.500 % N/A N/A $ 720,551 7.000 % Customers Bank $ 1,164,652 11.323 % $ 462,842 4.500 % $ 668,549 6.500 % $ 719,976 7.000 % Tier 1 capital (to risk-weighted assets) Customers Bancorp, Inc. $ 1,039,281 10.096 % $ 617,615 6.000 % N/A N/A $ 874,955 8.500 % Customers Bank $ 1,164,652 11.323 % $ 617,122 6.000 % $ 822,829 8.000 % $ 874,256 8.500 % Total capital (to risk-weighted assets) Customers Bancorp, Inc. $ 1,256,309 12.205 % $ 823,487 8.000 % N/A N/A $ 1,080,827 10.500 % Customers Bank $ 1,330,155 12.933 % $ 822,829 8.000 % $ 1,028,537 10.000 % $ 1,079,964 10.500 % Tier 1 capital (to average assets) Customers Bancorp, Inc. $ 1,039,281 9.258 % $ 449,026 4.000 % N/A N/A $ 449,026 4.000 % Customers Bank $ 1,164,652 10.379 % $ 448,851 4.000 % $ 561,064 5.000 % $ 448,851 4.000 % The Basel III Capital Rules require that we maintain a 2.500% capital conservation buffer with respect to each of CET1, Tier 1 and total capital to risk-weighted assets, which provides for capital levels that exceed the minimum risk-based capital adequacy requirements. A financial institution with a conservation buffer of less than the required amount is subject to limitations on capital distributions, including dividend payments and stock repurchases, and certain discretionary bonus payments to executive officers.

Disclosures About Fair Value of

Disclosures About Fair Value of Financial Instruments	3 Months Ended

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 Topic 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 , 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 March 31, 2020 and December 31, 2019: Financial Instruments Recorded at Fair Value on a Recurring Basis Investment securities: The fair values of equity securities, available for sale 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). 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. 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. 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 , in which the Bank has measured impairment generally based on the fair value of the loan’s collateral or discounted cash flow analysis. Fair value is generally determined based upon independent third-party appraisals of the properties that collateralize the loans, discounted cash flows 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. Other real estate owned: The fair value of OREO is determined by using appraisals, which may be discounted based on management’s review and changes in market conditions or sales agreements with third parties. All appraisals must be performed in accordance with the Uniform Standards of Professional Appraisal Practice. Appraisals are certified to the Bank and performed by appraisers on the Bank’s approved list of appraisers. Evaluations are completed by a person independent of management. The content of the appraisal depends on the complexity of the property. Appraisals are completed on a “retail value” and an “as is value”.

The following table summarizes financial assets and financial liabilities measured at fair value as of March 31, 2020 and December 31, 2019 on a recurring and nonrecurring basis for which Customers utilized Level 3 inputs to measure fair value. The unobservable Level 3 inputs noted below contain a level of uncertainty that may differ from what is realized in an immediate settlement of the assets. Therefore, Customers may realize a value higher or lower than the current estimated fair value of the assets. The interest-only GNMA securities are Level 3 assets measured at fair value on a recurring basis under a fair value option election. For the three months ended March 31, 2020, cash settlements of $1.0 million were applied to the carrying value of the interest-only GNMA securities, net of premium amortization expense. At March 31, 2020, Customers used an internally developed discounted cash flow model to value the interest-only GNMA securities. The significant unobservable input used in the discounted cash flow model included prepayment speed. Significant increases (decreases) in this input would result in a significantly lower (higher) fair value measurement.

Derivative Instruments and Hedg

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 a service 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 accumulated other comprehensive income (loss) 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 accumulated other comprehensive income (loss) are reclassified immediately into earnings and any subsequent changes in the fair value of such derivatives are recognized directly in earnings. Amounts reported in accumulated other comprehensive income (loss) related to derivatives will be reclassified to interest expense as interest payments are made on Customers' variable-rate debt and a variable-rate deposit relationship. Customers expects to reclassify $14.6 million of losses from accumulated other comprehensive income (loss) to interest expense during the next 12 months. Customers is hedging its exposure to the variability in future cash flows for forecasted transactions (3-month FHLB advances and Fed fund purchases) and a variable-rate deposit relationship over a maximum period of 73 months (excluding forecasted transactions related to the payment of variable interest on existing financial instruments). At March 31, 2020, Customers had five outstanding interest rate derivatives with notional amounts totaling $1.1 billion that were designated as cash flow hedges of interest-rate risk. At December 31, 2019, Customers had four outstanding interest rate derivatives with notional amounts totaling $725.0 million that were designated as cash flow hedges of interest rate-risk. The outstanding cash flow hedges at March 31, 2020 expire between June 2021 and May 2026. 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 March 31, 2020, Customers had 152 interest rate swaps with an aggregate notional amount of $1.5 billion and four interest rate caps with an aggregated notional amount of $77.6 million related to this program. At December 31, 2019, Customers had 140 interest rate swaps with an aggregate notional amount of $1.4 billion and four interest rate caps with an aggregate notional amount of $78.6 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 March 31, 2020 and December 31, 2019, Customers had an outstanding notional balance of residential mortgage loan commitments of $12.5 million and $4.5 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 reported directly in earnings. At March 31, 2020 and December 31, 2019, Customers had outstanding notional balances of credit derivatives of $172.4 million and $167.1 million, respectively. Fair Value of Derivative Instruments on the Balance Sheet The following tables present the fair value of Customers' derivative financial instruments as well as their presentation on the balance sheet as of March 31, 2020 and December 31, 2019.

See NOTE 4 - CHANGES IN ACCUMULATED OTHER COMPREHENSIVE INCOME (LOSS) for the total effect on other comprehensive income (loss) from derivatives designated as cash flow hedges for the periods presented. Credit-risk-related Contingent Features By entering into derivative contracts, Customers is exposed to credit risk. 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. 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 March 31, 2020, the fair value of derivatives in a net liability position (which includes accrued interest but excludes any adjustment for nonperformance-risk) related to these agreements was $118.5 million. In addition, Customers, which has collateral posting thresholds with certain of these counterparties, had posted $117.6 million of cash as collateral at March 31, 2020. Customers records cash posted as collateral as a reduction in the outstanding balance of cash and cash equivalents and an increase in the balance of other assets. 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 table below.

Segment Reporting [Abstract]
Business Segments	BUSINESS SEGMENTS Customers’ segment financial reporting reflects the manner in which its chief operating decision makers allocate resources and assess performance. Management has determined that Customers’ operations consist of two reportable segments - Customers Bank Business Banking and BankMobile. Each segment generates revenues, manages risk, and offers distinct products and services to targeted customers through different delivery channels. The strategy, marketing and analysis of these segments vary considerably. The Customers Bank Business Banking segment is delivered predominately to commercial customers in Southeastern Pennsylvania, New York, New Jersey, Massachusetts, Rhode Island, New Hampshire, Washington, D.C., and Illinois through a single-point-of-contact business model and provides liquidity to residential mortgage originators nationwide through commercial loans to mortgage companies. Lending and deposit gathering activities are focused primarily on privately held businesses, high-net-worth families, selected commercial real estate lending, commercial mortgage companies, and equipment finance. Revenues are generated primarily through net interest income (the difference between interest earned on loans and leases, investments, and other interest earning assets and interest paid on deposits and other borrowed funds) and other non-interest income, such as mortgage warehouse transactional fees and BOLI. The BankMobile segment provides state-of-the-art high-tech digital banking and disbursement services to consumers, students, and the "under banked" nationwide, along with "Banking as a Service" offerings with white label partners. BankMobile is a full-service fintech banking platform that is accessible to customers anywhere and anytime through the customer's smartphone or other web-enabled device. Revenues are currently being generated primarily through interest income on other consumer loans, interchange and card revenue, deposit and wire transfer fees and university fees. The majority of expenses for BankMobile are related to the segment's operation of the ongoing business acquired through the Disbursement business acquisition and costs associated with the development of white label products for its partner. The following tables present the operating results for Customers' reportable business segments for the three months ended March 31, 2020 and 2019. The segment financial results include directly attributable revenues and expenses. Consistent with the presentation of segment results to Customers' chief operating decision makers, overhead costs and preferred stock dividends are assigned to the Customers Bank Business Banking segment. The tax benefit assigned to BankMobile was based on an estimated effective tax rate of 20.35% for 2020 and 23.15% for 2019, respectively.

Commitments and Contingencies Disclosure [Abstract]
Loss Contingencies	LOSS CONTINGENCIES Loss contingencies, including claims and legal actions arising in the ordinary course of business, are recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated. 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.

On January 30, 2017, Customers Bank filed Preliminary Objections to the Complaint seeking dismissal of Plaintiff’s claims against Customers Bank and Robert White, named as co-defendants. In response to the Preliminary Objections, Lifestyle filed an Amended Complaint against Customers Bank and Robert White. Customers Bank has filed Preliminary Objections to the Second Amended Complaint seeking dismissal of Plaintiff's claim against Customers Bank and Robert White, named as co-defendants. The Court has dismissed certain counts and determined to allow certain other counts to proceed. Customers Bank intends to vigorously defend itself against these allegations but is currently unable to predict the outcome of this lawsuit and therefore cannot determine the likelihood of loss nor estimate a range of possible loss. United States Department of Education Matter In third quarter 2018, Customers received a Final Program Review Determination ("FPRD") letter dated September 5, 2018 from the DOE regarding a focused program review of Higher One's/Customers Bank's administration, as a third party servicer, of the programs authorized pursuant to Title IV of the Higher Education Act of 1965. The DOE program review covered the award years beginning in 2013 through the FPRD issuance date, including the time period when Higher One was acting as the third party servicer prior to Customers' acquisition of the Disbursement business on June 15, 2016. The FPRD determined that, with respect to students enrolled at specified partner institutions, Higher One/Customers did not provide convenient fee-free access to ATMs or bank branch offices in such locations as required by the DOE’s cash management regulations. Those regulations, which were in effect during the period covered by the program review and were revised during that period, seek, among other purposes, to ensure that students can make fee-free cash withdrawals. The FPRD determined that students incurred prohibited costs in accessing Title IV credit balance funds, and the FPRD classifies those costs as financial liabilities of Customers. The FPRD also requires Customers to take prospective action to increase ATM access for students at certain of its partner institutions. Customers disagreed with the FPRD and appealed the asserted financial liabilities of $6.5 million, and a request for review has been submitted to trigger an administrative process before the DOE’s Office of Hearing and Appeals. On March 26, 2020, the DOE and Customers filed a Joint Motion to Dismiss with Prejudice (the "Joint Motion") with the United States Department of Education. The Joint Motion states that the DOE and Customers reached an agreement that resolves the liabilities at issue in the appeal. The Joint Motion was granted on April 27, 2020. As part of the settlement, the liabilities assessed in the FPRD were reduced to $3.0 million (the "settlement amount"). Customers had previously recorded a liability in the amount of $1.0 million during third quarter 2019 and increased its liability by an additional $1.0 million in first quarter 2020. The remaining $1.0 million is expected to be funded from funds in an escrow account set-up at the time of Customers' acquisition of the Disbursement business from Higher One in 2016. Bureau of the Fiscal Service Notice of Direct Debit (U.S. Treasury Check Reclamation) On June 21, 2019, Customers received a Notice of Direct Debit (U.S. Treasury Check Reclamation) from the Bureau of the Fiscal Service (“Reclamation Notice”). The Reclamation Notice represented a demand to Customers for the return of funds on a U.S. Treasury check for approximately $5.4 million. Customers filed a written protest pursuant to Code of Federal Regulations, Title 31, Chapter II, Part 240, which resulted in a suspension of the direct debit by the Bureau of the Fiscal Service. On January 31, 2020, Customers received an Abandonment Notice from the Bureau of Fiscal Service instructing Customers to disregard the Notice of Direct Debit as the Bureau of Fiscal Service would not be seeking reclamation of these funds.

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, 2019 consolidated balance sheet presented in this report has been derived from Customers Bancorp’s audited 2019 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 2019 consolidated financial statements of Customers Bancorp and subsidiaries included in Customers' Annual Report on Form 10-K for the year ended December 31, 2019 filed with the SEC on March 2, 2020 (the "2019 Form 10-K"). The 2019 Form 10-K describes Customers Bancorp’s significant accounting policies, which include its policies on Principles of Consolidation; Cash and Cash Equivalents and Statements of Cash Flows; Restrictions on Cash and Amounts due from Banks; Business Combinations; Investment Securities; Loan Accounting Framework; Loans Held for Sale and Loans at Fair Value; Loans Receivable - Mortgage Warehouse, at Fair Value; Loans and Leases Receivable; Purchased Loans; ALLL; Goodwill and Other Intangible Assets; FHLB, Federal Reserve Bank, and Other Restricted Stock; OREO; BOLI; Bank Premises and Equipment; Lessor Operating Leases; Treasury Stock; Income Taxes; Share-Based Compensation; Transfer of Financial Assets; Segment Information; Derivative Instruments and Hedging; Comprehensive Income (Loss); EPS; Loss Contingencies; and Collaborative Arrangements. There have been no material changes to Customers Bancorp's significant accounting policies noted above for the three months ended March 31, 2020, except for the adoption of ASU 2016-13 Financial Instruments - Credit Losses ("ASC 326"): Measurement of Credit Losses on Financial Instruments, which is discussed below in Adoption of New Accounting Standard, and replaces our prior ALLL policy.
Recently Issued Accounting Standards	New Accounting Standards Presented below are recently issued accounting standards that Customers has adopted as well as those that the FASB has issued but are not yet effective. Accounting Standards Adopted in 2020 Allowance for Credit Losses On January 1, 2020, Customers adopted ASC 326, which replaced the incurred loss methodology with an expected loss methodology that is referred to as CECL methodology. The measurement of expected credit losses under the CECL methodology is applicable to financial assets measured at amortized cost, including loan receivables and net investments in leases recognized by Customers as a lessor in accordance with ASC 842. CECL also applies to off-balance sheet credit exposures not accounted for as insurance, such as loan commitments, standby letters of credit, financial guarantees, and other similar instruments. ASC 326 also made changes to the accounting for AFS debt securities, which now requires credit losses to be presented as an allowance, rather than as a write-down on AFS debt securities that management does not intend to sell or believes that it is more likely than not they will not be required to sell. Allowance for Credit Losses on Loans and Leases The allowance for credit losses on loans and leases is a valuation account that is deducted from the loan or lease’s amortized cost basis to present the net amount expected to be collected on the loans and leases. Loans and leases deemed to be uncollectible are charged against the allowance for credit losses on loans and leases, and subsequent recoveries, if any, are credited to the allowance for credit losses on loans and leases. Expected recoveries do not exceed the aggregate of amounts previously charged-off and expected to be charged-off. Changes to the allowance for credit losses on loans and leases are recorded through the provision for credit losses on loans and leases. The allowance for credit losses on loans and leases is maintained at a level considered appropriate to absorb expected credit losses over the expected life of the portfolio as of the reporting date. The allowance for credit losses on loans and leases is measured on a collective (pool) basis when similar risk characteristics exist. Customers' loan portfolio segments include commercial and consumer. Each of these two loan portfolio segments is comprised of multiple loan classes. Loan classes are characterized by similarities in loan type, collateral type, risk attributes and the manner in which credit risk is assessed and monitored. The commercial segment is composed of multi-family, commercial and industrial, commercial real estate owner occupied, commercial real estate non-owner occupied and construction loan classes. The consumer segment is composed of residential real estate, manufactured housing and other consumer. Loans that do not share risk characteristics are evaluated on an individual basis. Loans evaluated individually are not also included in the collective evaluation. For individually assessed loans, see related details in the Individually Assessed Loans section below. The allowance for credit losses on collectively assessed loans and leases is measured over the expected life of the loan or lease using lifetime loss rate models which consider historical loan performance, loan or borrower attributes and forecasts of future economic conditions in addition to information about past events and current conditions. Significant loan/borrower attributes utilized in the models include origination date, maturity date, collateral property type, internal risk rating, delinquency status, borrower state and FICO score at origination. Customers uses external sources in the creation of its forecasts, including current economic conditions and forecasts for macroeconomic variables over its reasonable and supportable forecast period (e.g., GDP growth rate, unemployment rate, BBB spread, commercial real estate and home price index). After the reasonable and supportable forecast period, which ranges from two to five years, the models revert the forecasted macroeconomic variables to their historical long-term trends, without specific predictions for the economy, over the expected life of the pool. The lifetime loss rate models also incorporate prepayment assumptions into estimated lifetime loss rates. Customers runs the CECL impairment models on a quarterly basis and qualitatively adjusts model results for risk factors that are not considered within the models but which are relevant in assessing the expected credit losses within the loan and lease pools. Management generally considers the following qualitative factors: • Volume and severity of past-due loans, non-accrual loans and classified loans; • Lending policies and procedures, including underwriting standards and historically based loss/collection, charge-off and recovery practices; • Nature and volume of the portfolio; • Existence and effect of any credit concentrations and changes in the level of such concentrations; • Risk ratings; • The value of the underlying collateral for loans that are not collateral dependent; • Changes in the quality of the loan review system; • Experience, ability and depth of lending management and staff; • Other external factors, such as changes in legal, regulatory or competitive environment; and • Model and data limitations. Customers has elected to not estimate an allowance for credit losses on accrued interest receivable, as it already has a policy in place to reverse or write-off accrued interest, through interest income, in a timely manner. Accrued interest receivable is presented as part of other assets in the consolidated balance sheet. Purchased Credit Deteriorated (“PCD”) Loans and Leases PCD assets are acquired individual loans and leases (or acquired groups of loans and leases with similar risk characteristics) that, as of the date of acquisition, have experienced a more-than-insignificant deterioration in credit quality since origination, as determined by an acquirer’s assessment. PCD loans and leases are recorded at their purchase price plus the allowance for credit losses expected at the time of acquisition, or “gross up” of the amortized cost basis. The January 1, 2020 transition adjustment discussed above was established for these loans and leases without affecting the income statement or retained earnings. Changes in the current estimate of the allowance for credit losses after acquisition from the estimated allowance previously recorded are reported in the income statement as provision for credit losses expense or reversal of provision for credit losses in subsequent periods as they arise. Purchased loans or leases that do not qualify as PCD assets are accounted for similar to originated assets, whereby an allowance for credit losses is recognized with a corresponding increase to the income statement provision for credit losses. Evidence that purchased loans and leases, measured at amortized cost, have more-than-insignificant deterioration in credit quality since origination and, therefore meet the PCD definition, may include loans and leases that are past-due, in non-accrual status, poor borrower credit score, recent loan-to-value percentages and other standard indicators (i.e., TDR, charge-offs and bankruptcy). Allowance for Credit Losses on Lending-Related Commitments Customers estimates expected credit losses over the contractual period in which it is exposed to credit risk on contractual obligations to extend credit, unless the obligation is unconditionally cancellable by Customers. The allowance for credit losses on lending-related commitments is recorded in accrued interest payable and other liabilities in the consolidated balance sheet and is recorded as a provision for credit losses within other non-interest expense in the consolidated income statement. The estimate includes consideration of the likelihood that funding will occur and an estimate of expected credit losses on commitments expected to be funded over their estimated lives. Customers estimates the expected credit losses for undrawn commitments using a usage given default calculation. The lifetime loss rates for off-balance sheet credit exposures are calculated in the same manner as on-balance sheet credit exposures, using the same models and economic forecasts, adjusted for the estimated likelihood that funding will occur. Individually Assessed Loans and Leases ASC 326 provides that a loan or lease is measured individually if it does not share similar risk characteristics with other financial assets. For Customers, loans and leases which are identified to be individually assessed under CECL typically would have been evaluated individually as impaired loans using accounting guidance in effect in periods prior to the adoption of CECL and include troubled debt restructurings (TDRs) and collateral dependent loans. TDRs A loan for which the terms have been modified resulting in a concession, and for which the borrower is experiencing financial difficulties is considered to be a TDR. The allowance for credit loss on a TDR is measured using the same method as all other loans held for investment, except in cases when the value of a concession cannot be measured using a method other than the discounted cash flow (“DCF”) method. When the value of a concession is measured using the DCF method, the allowance for credit loss is determined by discounting the expected future cash flows at the original effective interest rate of the loan. Collateral Dependent Loans Customers considers a loan to be collateral dependent when foreclosure of the underlying collateral is probable. Customers has also elected to apply the practical expedient to measure expected credit losses of a collateral dependent asset using the fair value of the collateral, less any estimated costs to sell, when foreclosure is not probable but repayment of the loan is expected to be provided substantially through the operation or sale of the collateral, and the borrower is experiencing financial difficulty. Allowance for Credit Losses on Available for Sale Securities For AFS debt securities in an unrealized loss position, Customers first assesses whether it intends to sell, or it is more likely than not that it will be required to sell the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the security’s amortized cost basis is written down to fair value through income. For AFS debt securities that do not meet the aforementioned criteria, Customers evaluates whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, management considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency, and adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses on AFS securities is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost basis. Any impairment that has not been recorded through an allowance for credit losses on AFS securities is recognized in other comprehensive income. Changes in the allowance for credit losses on AFS securities are recorded as provision, or reversal of provision for credit losses on AFS securities in other non-interest income within the consolidated income statement. Losses are charged against the allowance for credit losses on AFS securities when management believes the uncollectibility of an AFS security is confirmed or when either of the criteria regarding intent or requirement to sell is met. Accrued interest receivable on AFS debt securities totaled $4.7 million at March 31, 2020 and is excluded from the estimate of credit losses.

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 Topic 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 , 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 a service 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.

Summary of Financial Assets and Financial Liabilities Measured at Fair Value on Recurring and Nonrecurring Basis	The following table summarizes financial assets and financial liabilities measured at fair value as of March 31, 2020 and December 31, 2019 on a recurring and nonrecurring basis for which Customers utilized Level 3 inputs to measure fair value. The unobservable Level 3 inputs noted below contain a level of uncertainty that may differ from what is realized in an immediate settlement of the assets. Therefore, Customers may realize a value higher or lower than the current estimated fair value of the assets. The interest-only GNMA securities are Level 3 assets measured at fair value on a recurring basis under a fair value option election. For the three months ended March 31, 2020, cash settlements of $1.0 million were applied to the carrying value of the interest-only GNMA securities, net of premium amortization expense. At March 31, 2020, Customers used an internally developed discounted cash flow model to value the interest-only GNMA securities. The significant unobservable input used in the discounted cash flow model included prepayment speed. Significant increases (decreases) in this input would result in a significantly lower (higher) fair value measurement.
