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 the 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.

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 installment. 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

13

Table of Contents

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 indices). 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 a separate financial statement line item 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, 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 TDRs and collateral dependent loans.

14

Table of Contents

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 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.

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 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.

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 $4.2 million at September 30, 2020 and is excluded from the estimate of credit losses.

Accounting and Reporting Considerations related to COVID-19

On March 27, 2020, the CARES Act was signed into law and contained substantial tax and spending provisions intended to address the impact of the COVID-19 pandemic and stimulate the economy. The CARES Act includes the PPP designed to aid small-and medium-sized businesses through federally guaranteed loans distributed through banks. Customers is a participant in the PPP. Section 4013 of the CARES act also gives entities temporary relief from the accounting and disclosure requirements for TDRs under ASC 310-40 in certain situations.

Accounting for PPP Loans

In April 2020, Customers began to originate loans to qualified small businesses under the PPP administered by the SBA. The PPP loans are fully guaranteed by the SBA and may be eligible for forgiveness by the SBA to the extent that the proceeds are used for payroll and other permitted purposes in accordance with the requirements of the PPP. These loans carry a fixed rate of 1.00% and terms of two or five years, if not forgiven, in whole or in part. Payments are deferred for the first six months of the loan. The loans are 100% guaranteed by the SBA. The SBA pays the originating bank a processing fee ranging from 1% to 5% based on the size of the loan. Customers classified the PPP loans as held for investment and these loans are carried at amortized cost and interest income is recognized using the interest method. The origination fees, net of direct origination costs, are deferred and recognized as an adjustment to the yield of the related loans over their contractual life using the interest method. As PPP is newly created, Customers does not have historical prepayment data to accurately estimate principal prepayments and therefore has elected to not estimate prepayments as a policy election. No allowance for credit losses has been recognized for PPP loans as these loans are 100% guaranteed by the SBA. See Note 7 - Loans and Leases Receivable and Allowance for Credit Losses on Loans and Leases for additional information.

Loan Modifications

As mentioned above, Section 4013 of the CARES Act gives entities temporary relief from the accounting and disclosure requirements for TDRs. In addition, on April 7, 2020, certain regulatory banking agencies issued an interagency statement that offers practical expedients for evaluating whether loan modifications in response to the COVID-19 pandemic are TDRs. To qualify for TDR accounting and disclosure relief under the CARES Act, the applicable loan must not have been more than 30 days past due as of December 31, 2019, and the modification must be executed during the period beginning on March 1, 2020, and ending on the earlier of December 31, 2020, or the date that is 60 days after the termination date of the national emergency declared by the president on March 13, 2020, under the National Emergencies Act related to the outbreak of COVID-19. The CARES Act applies to modifications made as a result of COVID-19 including: forbearance agreements, interest rate modifications, repayment plans, and other arrangements to defer or delay payment of principal or interest. The interagency statement does not require the modification to be completed within a certain time period if it is related to COVID-19 and can be provided to borrowers either individually or as part of a loan modification program. Moreover, the interagency statement applies to short-term modifications (e.g. not more than six months deferral) including payment deferrals, fee waivers, extensions of repayment terms, or other insignificant payment delays as a result of COVID-19.

Customers applied Section 4013 of the CARES Act and the interagency statement in connection with applicable modifications. For modifications that qualify under either the CARES Act or the interagency statement, TDR accounting and reporting is suspended. These modifications generally involve principal and/or interest payment deferrals for a period of 90 days at a time and can be extended to six months or longer for modifications that qualified under the Section 4013 of the CARES Act if requested by the borrower as long as the reason is still related to COVID-19. These modified loans would not also be reported as past due or nonaccrual during the deferral period. See Note 7 - Loans and Leases Receivable and Allowance for Credit Losses on Loans and Leases for additional information.

At September 30, 2020, there were fifteen 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 were principally due to changes in market interest rates that resulted in a negative impact on the respective securities' fair value. All amounts related to these securities are expected to be recovered when market prices recover or at maturity. Customers does not intend to sell any of the 15 securities, and it is not more likely than not that Customers will be required to sell any of the 15 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 September 30, 2020 and December 31, 2019, Customers Bank had pledged investment securities aggregating $20.1 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 September 30, 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.

and December 31, 2019, respectively, and is presented in accrued interest receivable in the consolidated balance sheet. At September 30, 2020, there were $32.1 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.

Loans receivable, PPP:

On March 27, 2020, the CARES Act was signed into law and created funding for a new product called the PPP. The PPP is administered by the SBA and is intended to assist organizations with payroll related expenses. Customers had $5.0 billion of PPP loans outstanding as of September 30, 2020, which are fully guaranteed by the SBA and earn a fixed interest rate of 1.00%. Customers recognized interest income, including origination fees, of $24.3 million and $36.0 million for the three and nine months ended September 30, 2020, respectively.

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 September 30, 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.

(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. The September 30, 2020 table excludes PPP loans of $5.0 billion which are all current as of September 30, 2020.

(3)Includes purchased credit deteriorated loans of $14.4 million at September 30, 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.

At September 30, 2020, the ACL was $155.6 million, an increase of $19.4 million from the January 1, 2020 balance of $136.2 million. The increase resulted primarily from the impact of reserve build for the COVID-19 pandemic including the change in macroeconomic forecasts, an increase in net charge-offs, mostly attributed to the commercial real estate non-owner occupied and installment portfolios, and portfolio growth mainly in the installment portfolio. Commercial real estate non-owner occupied charge-offs are attributable to two collateral dependent loans. Installment charge-offs are attributable to delinquencies and defaults of originated and purchased unsecured consumer installment loans through arrangements with fintech companies and other market place lenders.

PPP loans include an embedded credit enhancement guarantee from the SBA, which guarantees 100% of all principal and interest owed by the borrower. Therefore, Customers did not include an ACL for PPP loans as of September 30, 2020.

Troubled Debt Restructurings

At September 30, 2020 and December 31, 2019, there were $16.1 million and $13.3 million, respectively, in loans reported as TDRs. TDRs are reported as impaired loans in the quarter of their restructuring and are evaluated to determine whether they should be placed on non-accrual status. In subsequent quarters, a TDR may be returned to accrual status if it satisfies a minimum performance requirement of six months, however, it will remain classified as impaired. Generally, the Bank requires sustained performance for nine months before returning a TDR to accrual status. Customers had no lease receivables that had been restructured as a TDR as of September 30, 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 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. At September 30, 2020, commercial and consumer deferments related to COVID-19 were $79.0 million and $25.0 million, respectively.

The following table presents loans modified in a TDR by type of concession for the three and nine months ended September 30, 2020 and 2019. There were no modifications that involved forgiveness of debt for the three and nine months ended September 30, 2020 and 2019.

As of September 30, 2020 and 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:

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 September 30, 2020, the amortized cost basis of PCD assets amounted to $14.4 million.

Credit Quality Indicators

The ACL represents management's estimate of expected losses in Customers' loans and leases receivable portfolio, excluding commercial mortgage warehouse loans reported at fair value pursuant to a fair value option election and PPP loans receivable. Multi-family, commercial and industrial, owner occupied commercial real estate, non-owner occupied commercial real estate, and construction loans are rated based on an internally assigned risk rating system which is assigned at the time of loan origination and reviewed on a periodic, or on an “as needed” basis. Residential real estate loans, manufactured housing and installment loans are evaluated based on the payment activity of the loan.

To facilitate the monitoring of credit quality within the multi-family, commercial and industrial, owner occupied commercial real estate, non-owner occupied commercial real estate, and construction loan portfolios, and as an input in the ACL lifetime loss rate model for the 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

29

Table of Contents

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 September 30, 2020 and December 31, 2019. PPP loans are excluded in the tables below as these loans are fully guaranteed by the SBA.

Loans Pledged as Collateral

Customers has pledged eligible real estate and commercial and industrial loans as collateral for borrowings from the FHLB and FRB in the amount of $8.9 billion and $4.6 billion at September 30, 2020 and December 31, 2019, respectively. The increase in loans pledged as collateral relates to $4.8 billion of PPP loans that were pledged to the FRB in accordance with borrowing from the PPPLF.

NOTE 8 — LEASES

Lessee

Customers has operating leases for its branches, LPOs, and administrative offices, with remaining lease terms ranging between 2 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:

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 Customers' Split-TRAC leases have 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.

COVID-19 Impact on Leases

Customers granted concessions to lessees as a result of the business impact of the COVID-19 pandemic. At September 30, 2020, the book value of finance and operating leases with payment deferments were $31.0 million and $16.0 million, respectively. The concessions did not have a material impact in interest income from leases for the three months and nine months ended September 30, 2020. Additionally, Customers did not receive any concessions on its operating leases in which Customers is the lessee.

Customers Bank has the ability to call the subordinated notes, in whole, or in part, at a redemption price equal to 100% of the principal balance at certain times on or after June 26, 2024.

NOTE 10 — REGULATORY CAPITAL

The Bank and the Bancorp are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet the minimum capital requirements can result in certain mandatory, and possibly additional discretionary, actions by regulators that, if undertaken, could have a direct material effect on Customers' financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Bank and the Bancorp must meet specific capital guidelines that involve quantitative measures of their assets, liabilities and certain off-balance sheet items, as calculated under the regulatory accounting practices. The capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors. Prompt corrective action provisions are not applicable to bank holding companies.

In first quarter 2020, U.S federal banking regulatory agencies permitted banking organizations to phase-in, for regulatory capital purposes, the day-one impact of the new CECL accounting rule on retained earnings over a period of three years. As part of its response to the impact of COVID-19, on March 31, 2020, the U.S. federal banking regulatory agencies issued an interim final rule that provided the option to temporarily delay certain effects of CECL on regulatory capital for two years, followed by a three-year transition period. The interim final rule allows banking organizations to delay for two years 100% of the day-one impact of adopting CECL and 25% of the cumulative change in the reported allowance for credit losses since adopting CECL. Customers has elected to adopt the interim final rule, which is reflected in the regulatory capital data presented below.

Table of Contents

In April 2020, the U.S. federal banking regulatory agencies issued an interim final rule that permits banks to exclude the impact of participating in the SBA PPP program in their regulatory capital ratios. Specifically, PPP loans are zero percent risk weighted and a bank can exclude all PPP loans pledged as collateral to the PPPLF from its average total consolidated assets for purposes of calculating the Tier 1 capital to average assets ratio (i.e. leverage ratio). Customers applied this regulatory guidance in the calculation of its regulatory capital ratios presented below.

Quantitative measures established by regulation to ensure capital adequacy require the Bank and the Bancorp to maintain minimum amounts and ratios (set forth in the following table) of common equity Tier 1, Tier 1, and total capital to risk-weighted assets, and Tier 1 capital to average assets (as defined in the regulations). At September 30, 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:

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.

NOTE 11 — 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 September 30, 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.

37

Table of Contents

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”. These assets are classified as Level 3 fair values, based upon the lowest level of input that is significant to the fair value measurements.

The following table summarizes financial assets and financial liabilities measured at fair value as of September 30, 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.

NOTE 12 — 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 $15.9 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 federal funds purchased) and a variable-rate deposit relationship over a maximum period of 67 months (excluding forecasted transactions related to the payment of variable interest on existing financial instruments).

At September 30, 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 September 30, 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 September 30, 2020, Customers had 154 interest rate swaps with an aggregate notional amount of $1.4 billion and six interest rate caps with an aggregated notional amount of $122.1 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 September 30, 2020 and December 31, 2019, Customers had an outstanding notional balance of residential mortgage loan commitments of $19.4 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 September 30, 2020 and December 31, 2019, Customers had outstanding notional balances of credit derivatives of $172.9 million and $167.1 million, respectively.

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 September 30, 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 $114.5 million. In addition, Customers, which has collateral posting thresholds with certain of these counterparties, had posted $110.0 million of cash as collateral at September 30, 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.

NOTE 13 — 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 consumer installment 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 partners.

The following tables present the operating results for Customers' reportable business segments for the three and nine months ended September 30, 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 20.61% for 2020 and 23.15% for 2019, respectively.

NOTE 15 — 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.

Lifestyle Healthcare Group, Inc. Matter

On January 9, 2017, Lifestyle Healthcare Group, Inc., et al (“Plaintiffs”) filed a Complaint captioned Lifestyle Healthcare Group, Inc.; Fred Rappaport; Victoria Rappaport; Lifestyle Management Group, LLC Trading as Lifestyle Real Estate I, LP; Lifestyle Real Estate I GP, LLC; Daniel Muck; Lifestyle Management Group, LLC; Lifestyle Management Group, LLC Trading as Lifestyle I, LP D/B/A Lifestyle Medspa, Plaintiffs (“Lifestyle Parties”) v. Customers Bank, Robert White; Saldutti Law, LLC a/k/a Saldutti Law Group; Robert L. Saldutti, Esquire; and Michael Fuoco, Civil Action No. 01206, in the First Judicial District of Pennsylvania, Court of Common Pleas of Philadelphia. In this Complaint, the Plaintiffs generally allege wrongful use of civil proceedings and abuse of process in connection with a case filed and later dismissed in federal court, titled, Customers Bank v. Fred Rappaport, et al., U.S.D.C.E.D. Pa., No. 15-6145. 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 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 dismissed certain counts and determined to allow certain other counts to proceed. On September 17, 2020, a Stipulation of Dismissal with Prejudice was filed with the Court as a result of the voluntary resolution of the matter by and between Plaintiffs and defendants, Customers Bank, Robert White and Michael Fuoco only.

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 ED 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 ED 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 ED’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 ED’s Office of Hearing and Appeals.

On March 26, 2020, the ED 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 ED 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.

NOTE 16 — BANKMOBILE TECHNOLOGIES, INC. MERGER

On August 6, 2020, Customers Bank, BMT, a subsidiary of Customers Bank, and MFAC, a special purpose acquisition company, entered into a definitive merger agreement. BMT is the technology arm of Customers' BankMobile reporting segment. Upon closing of the transaction, the combined company will operate as BM Technologies and expects to be listed on the New York Stock Exchange. All BMT serviced deposits and loans will remain at the Bank immediately after the closing of the transaction. Upon the closing of the transaction, BM Technologies will be a financial technology company bringing banks and business partners together through its digital banking platform.

Merger Consideration

The aggregate consideration to be paid in connection with the merger will be an amount (the “Merger Consideration”) equal to: (i) $140.0 million minus (ii) $9.3 million (representing a sponsor equity adjustment), plus (or minus, if negative) (iii) BMT’s net working capital less a target net working capital of $10.0 million, minus (iv) the aggregate amount of any outstanding indebtedness of BMT at closing, and minus (v) the amount of any unpaid transaction expenses of BMT, MFAC’s transaction expenses and other liabilities of MFAC due and owing at the closing of the transaction.

The Merger Consideration will consist of cash and stock. The cash portion of the Merger Consideration (“Cash Consideration”) will be equal to (i) the amount of any proceeds of the PIPE Investment; plus (ii) an amount equal to one-half (1/2) of the difference between the (A) cash and cash equivalents of MFAC, including any funds in the trust account after giving effect to the completion of the redemption of shares of MFAC’s public stockholders (“Redemption”), less (B) a cash reserve to be used for the benefit of BM Technologies in the Merger, in the amount of $10.0 million (such difference between clause (A) and (B) which resulting amount if otherwise negative shall be equal to zero, being which resulting amount if otherwise negative shall be equal to zero, being the “Remaining Trust Account Amount”); minus (iii) MFAC’s transaction expenses and other liabilities of MFAC due and owing at the Business Combination Closing; plus (iv) the cash and cash equivalents of BMT; minus (v) BMT’s unpaid transaction expenses; minus (vi) a cash reserve in the amount of $5.0 million. The stock portion of the Merger Consideration consists of a number of shares of MFAC’s Class A common stock with an aggregate value (the “Merger Consideration Share Amount”) equal to (a) the Merger Consideration, minus (b) the Cash Consideration, with Customers Bancorp's stockholders receiving a number of shares of MFAC Class A common stock equal to the Merger Consideration Share Amount, divided by $10.38 (the “Per Share Price”).

The Merger Consideration is subject to adjustment after the closing date based on confirmed amounts of the net working capital of BMT, the outstanding indebtedness of BMT and any unpaid transaction expenses of BMT, as of the closing date. The adjustment amount shall be the Merger Consideration as finally determined minus the estimated Merger Consideration that was issued at the closing date of the transaction. If the adjustment is a negative adjustment in favor of MFAC, the Bank will pay MFAC the absolute value of the adjustment amount in cash. If the adjustment is a positive adjustment in favor of BMT, MFAC will issue to the Bank an additional number of shares of Class A Common Stock of MFAC with a value equal to the adjustment amount (with each share valued at the per share price). The Merger Consideration is also subject to reduction for the indemnification obligations of the Bank.

Certain Relationships

Mr. Jay Sidhu, who currently serves as Chief Executive Officer and Chairman of the Board of Customers Bancorp and Executive Chairman of the Bank, also serves as a director of MFAC, is one of the managing members of MFAC’s sponsor and is a MFAC stockholder and also served as Executive Chairman of MFAC through August 7, 2020. Mr. Bhanu Choudhrie, who currently serves as a member of the board of directors of Customers Bancorp and the Bank also serves as a director of MFAC, is one of the managing members of MFAC’s sponsor and is a MFAC stockholder. Mr. Samvir Sidhu, the son of Jay Sidhu, currently serves as the Bank’s Vice Chairman and Chief Operating Officer and as Customers Bancorp’s Head of Corporate Development, previously served as the Chief Executive Officer of MFAC, currently serves as a director of MFAC and is a MFAC stockholder. Ms. Luvleen Sidhu, the daughter of Jay Sidhu, currently serves as the Chief Executive Officer and as a director of BMT and is expected to continue to serve in those roles with BM Technologies. Certain of these individuals also expect to participate in the private placement by MFAC of shares of its Class A common stock to be completed in connection with the closing.

In light of these relationships, Customers Bancorp appointed a special committee consisting of independent directors with their own counsel and financial advisors. The special committee reviewed the transaction, obtained a fairness opinion in connection with the transaction, and made a unanimous recommendation to Customers Bancorp’s board of directors for approval. Customers Bancorp’s board of directors approved the transaction by a majority vote, with the above-mentioned directors recusing themselves from the deliberation and voting process and no director voting against the transaction.

Amendment to the Merger Agreement

On November 2, 2020, the Bank, BMT and MFAC amended the merger agreement to provide, among other things, that the stock portion of the Merger Consideration will be distributed to Customers Bancorp's stockholders at the closing of the transaction and that there will be restrictions on the sale of these shares for twelve months after the closing of the merger, provided that these restrictions will end prior to such time upon the earlier of (1) the date after the closing date on which MFAC consummates a liquidation, merger, capital stock exchange, reorganization or other similar transaction with an unaffiliated third-party that results in all of MFAC’s stockholders having the right to exchange their shares of common stock for cash, securities or other property, and (2) the date on which the closing sale price of MFAC’s common stock equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations and recapitalizations and the like) for any 20 trading days within any 30 trading day period commencing at least 150 days after the closing date.

The merger is expected to close in the fourth quarter 2020, pending MFAC stockholders' approval, regulatory approval and the satisfaction or waiver of additional conditions to closing. As of September 30, 2020, BMT had an outstanding borrowing with the Bank totalling $40 million. All or a portion of this borrowing is expected to remain outstanding after the merger transaction. As of September 30, 2020, Customers has determined that the planned divestiture of BMT through this merger transaction did not qualify for reporting as a discontinued operation. BMT, as a component of the BankMobile segment, did not meet the criteria to be classified as held for sale as the merger transaction is subject to MFAC shareholders' approval, regulatory approval, and other required conditions to closing as discussed above. Accordingly, Customers continues to report the operating results of BMT within the BankMobile segment. See NOTE 13 - BUSINESS SEGMENTS.

(the "Bancorp" or "Customers Bancorp"), a financial holding company, and its wholly owned subsidiaries, including Customers Bank (the "Bank"), collectively referred to as "Customers" herein.  This information is intended to facilitate your understanding and assessment of significant changes and trends related to Customers' financial condition and results of operations as of and for the three and nine months ended September 30, 2020.  All quarterly information in this Management’s Discussion and Analysis is unaudited. You should read this section in conjunction with “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in Customers' 2019 Form 10-K.

Overview

Like most financial institutions, Customers derives the majority of its income from interest it receives on its interest-earning assets, such as loans, leases and investments. Customers' primary source of funds for making these loans, leases and investments are its deposits and borrowings, on which it pays interest. Consequently, one of the key measures of Customers' success is the amount of its net interest income, or the difference between the interest income on its interest-earning assets and the interest expense on its interest-bearing liabilities, such as deposits and borrowings. Another key measure is the difference between the interest income generated by interest earning assets and the interest expense on interest-bearing liabilities, relative to the amount of average interest earning assets, which is referred to as net interest margin.

BankMobile, a division of Customers Bank, derives a majority of its revenue from interest income on consumer installment loans, interchange and card revenue and deposit fees. On August 6, 2020, BMT, a subsidiary of Customers Bank, and MFAC, a special purpose acquisition company, entered into a definitive merger agreement. BMT is the technology arm of Customers' BankMobile reporting segment. Upon closing of the transaction, the combined company will operate as BM Technologies and expects to be listed on the New York Stock Exchange. All BMT serviced deposits and loans will remain at the Bank immediately after the closing of the

Table of Contents

transaction. Upon the closing of the transaction, BM Technologies will be a financial technology company bringing banks and business partners together through its digital banking platform. Customers has included a detailed discussion of the definitive merger agreement in NOTE 16 - BANKMOBILE TECHNOLOGIES, INC. MERGER to Customers' unaudited quarterly financial statements.

There is credit risk inherent in loans and leases requiring Customers to maintain an ACL to absorb credit losses on existing loans and leases that may become uncollectible. Customers maintains this allowance by charging a provision for credit losses on loan and lease losses against its operating earnings. Customers has included a detailed discussion of this process, as well as several tables describing its ACL, in NOTE 2 - SIGNIFICANT ACCOUNTING POLICIES AND BASIS OF PRESENTATION and NOTE 7 - LOANS AND LEASES RECEIVABLE AND ALLOWANCE FOR CREDIT LOSSES ON LOANS AND LEASES to Customers' unaudited quarterly financial statements.

Impact of COVID-19

In March 2020, the outbreak of COVID-19 was recognized as a pandemic by the World Health Organization. The spread of COVID-19 has created a global public health crisis that has resulted in unprecedented uncertainty, volatility and disruption in financial markets and in governmental, commercial and consumer activity in the United States and globally, including the markets that Customers serves. Governmental responses during the pandemic have included orders closing businesses not deemed essential and directing individuals to restrict their movements, observe social distancing and shelter in place. These actions, together with responses to the pandemic by businesses and individuals, have resulted in rapid decreases in commercial and consumer activity, temporary closures of many businesses that have led to a loss of revenues and a rapid increase in unemployment, material decreases in oil and gas prices and in business valuations, disrupted global supply chains, market downturns and volatility, changes in consumer behavior related to pandemic fears, related emergency response legislation and an expectation that Federal Reserve policy will maintain a low interest rate environment for the foreseeable future.

Customers has taken deliberate actions to ensure that it has the necessary balance sheet strength to serve its clients and communities, including increases in liquidity and reserves supported by a strong capital position. Customers' business and consumer customers are experiencing varying degrees of financial distress, which is expected to continue in the coming months. In order to protect the health of its customers and team members, and to comply with applicable government directives, Customers has modified its business practices, including restricting team member travel, directing team members to work from home insofar as is possible and implementing its business continuity plans and protocols to the extent necessary. Customers also has made donations that have resulted in more than $1 million, either directly or indirectly, to communities in its footprint for urgent basic needs and has been re-targeting existing sponsorship and grants to non-profit organizations to support COVID-19 related activities.

On March 27, 2020, the CARES Act was signed into law. It contains substantial tax and spending provisions intended to address the impact of the COVID-19 pandemic. The CARES Act includes the SBA's PPP, a nearly $350 billion program designed to aid small- and medium-sized businesses through federally guaranteed loans distributed through banks. These loans are intended to guarantee an eight-week or 24-week period of payroll and other costs to help those businesses remain viable and allow their workers to pay their bills. On April 16, 2020, the SBA announced that all available funds had been exhausted and applications were no longer being accepted. On April 22, 2020, an additional $310 billion of funds for the PPP was signed into law. On August 8, 2020, the SBA announced that the PPP was closed and no longer accepting PPP applications from participating lenders. As of September 30, 2020, Customers has helped thousands of small businesses by originating about $5.0 billion in PPP loans directly or through fintech partnerships.

In response to the COVID-19 pandemic, Customers has also implemented a short-term loan modification program to provide temporary payment relief to certain of its borrowers who meet the program's qualifications. This program allows for a deferral of payments for a maximum of 90 days at a time. The deferred payments along with interest accrued during the deferral period are due and payable on the maturity date of the existing loan. As of September 30, 2020, total commercial deferments declined to $79 million, or 0.7% of total loans and leases, excluding PPP loans, from a peak of $1.2 billion and total consumer deferments declined to $25 million, or 0.2% of total loans and leases, excluding PPP loans, from a peak of $108 million. As of September 30, 2020, Customers had $198.5 million of pending commercial loan deferment requests.

The FRB has taken a range of actions to support the flow of credit to households and businesses. For example, on March 15, 2020, the FRB reduced the target range for the federal funds rate to 0.00% to 0.25% and announced that it would increase its holdings of U.S. Treasury securities and agency mortgage-backed securities and begin purchasing agency commercial mortgage-backed securities. Additionally, on September 16, 2020, the FRB pledged to keep interest rates near zero until 2023 to support the economy through the COVID-19 recession. The FRB has also encouraged depository institutions to borrow from the discount window and has lowered the primary credit rate for such borrowing by 150 basis points while extending the term of such loans up to 90 days. Reserve requirements have been reduced to zero as of March 26, 2020. The FRB has also established, or has taken steps to establish, a range of facilities and programs to support the U.S. economy and U.S. marketplace participants in response to economic disruptions associated with

54

Table of Contents

COVID-19, including among others, Main Street Lending facilities to purchase loan participations, under specified conditions, from banks lending to small and medium U.S. businesses and the PPPLF, which was created to bolster the effectiveness of the PPP by taking loans as collateral at face value. While Customers has not participated in all of these facilities or programs to date, it may participate in some or all of these facilities or programs, including as a lender, agent, or intermediary on behalf of clients or customers at various times in the future. As of September 30, 2020, Customers borrowed $4.8 billion from the PPPLF to fund $5.0 billion of PPP loans outstanding as of September 30, 2020.

Significant uncertainties as to future economic conditions exist, and Customers has taken deliberate actions in response, including higher levels of on-balance sheet liquidity and maintaining strong capital ratios. Additionally, the economic pressures, coupled with the implementation of an expected lifetime loss methodology for determining our provision for credit losses as required by CECL have contributed to an increased provision for credit losses on loans and leases and off-balance sheet credit exposures in 2020. Customers continues to monitor the impact of COVID-19 closely, as well as any effects that may result from the CARES Act; however, the extent to which the COVID-19 pandemic will impact Customers' operations and financial results during the remainder of 2020 is highly uncertain.

New Accounting Pronouncements

For information about the impact that recently adopted, including CECL, or issued accounting guidance will have on us, please refer to NOTE 2 – SIGNIFICANT ACCOUNTING POLICIES AND BASIS OF PRESENTATION to Customers' interim unaudited financial statements.

Critical Accounting Policies

Customers has adopted various accounting policies that govern the application of U.S. GAAP and that are consistent with general practices within the banking industry in the preparation of its consolidated financial statements. Customers' significant accounting policies are described in “NOTE 2 - SIGNIFICANT ACCOUNTING POLICIES AND BASIS OF PRESENTATION” in Customers' audited financial statements included in its 2019 Form 10-K and updated in this Form 10-Q for the quarterly period ended September 30, 2020 in “NOTE 2 - SIGNIFICANT ACCOUNTING POLICIES AND BASIS OF PRESENTATION."

Certain accounting policies may involve significant judgments and assumptions by Customers that have a material impact on the carrying value of certain assets. Customers considers these accounting policies to be critical accounting policies. The judgment and assumptions used are based on historical experience and other factors, which are believed to be reasonable under the circumstances. Because of the nature of the judgments and assumptions management makes, actual results could differ from these judgments and estimates, which could have a material impact on the carrying values of Customers' assets.

The critical accounting policy that is both important to the portrayal of Customers' financial condition and results of operations and requires complex, subjective judgments is the ACL. This critical accounting policy and material estimate, along with the related disclosures, are reviewed by Customers' Audit Committee of the Board of Directors.

Allowance for Credit Losses

Customers' ACL at September 30, 2020 represents Customers' current estimate of the lifetime credit losses expected from its loan and lease portfolio and its unfunded lending-related commitments that are not unconditionally cancellable. Management estimates the ACL by projecting a lifetime loss rate conditional on a forecast of economic parameters and other qualitative adjustments, for the loans and leases' expected remaining term.

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, while also incorporating prepayment assumptions into its lifetime loss rates. Internal factors that impact the quarterly allowance estimate include the level of outstanding balances, portfolio performance and assigned risk ratings. Significant loan/borrower attributes utilized in the models include property type, initial loan to value, assigned risk ratings, delinquency status, origination date, maturity date, initial FICO scores, and borrower state.

The ACL may be affected materially by a variety of qualitative factors that Customers considers to reflect its current judgement of various events and risks that are not measured in our statistical procedures, including uncertainty related to the economic forecasts used in the modeled credit loss estimates, nature and volume of loan and lease portfolio, credit underwriting policy exceptions, peer comparison, industry data, and model and data limitations. The qualitative allowance for economic forecast risk is further informed by

multiple alternative scenarios to arrive at a composite scenario supporting the period-end ACL balance. The evaluation process is inherently imprecise and subjective as it requires significant management judgment based on underlying factors that are susceptible to changes, sometimes materially and rapidly. Customers recognizes that this approach may not be suitable in certain economic environments such that additional analysis may be performed at management's discretion. Due in part to its subjectivity, the qualitative evaluation may be materially impacted during periods of economic uncertainty and late breaking events that could lead to revision of reserves to reflect management's best estimate of expected credit losses.

The ACL is established in accordance with our ACL policy. The ACL Committee, which includes the Chief Financial Officer, Chief Accounting Officer, Chief Risk Officer, and Chief Credit Officer, among others, reviews the adequacy of the ACL each quarter, together with Customers' risk management team. The ACL policy, significant judgements and the related disclosures are reviewed by Customers' Audit Committee of the Board of Directors.

The significant increase in our estimated ACL as of September 30, 2020 as compared to our January 1, 2020 estimate was primarily attributable to the significant economic impact of COVID-19, along with loan growth in Customers' commercial and consumer loan portfolios. The total reserve build for the ACL for the nine months ended September 30, 2020 was $19.2 million, with a reduction of reserve for the ACL of $4.9 million for the three months ended September 30, 2020, for an ending balance of $158.9 million ($155.6 million for loans and leases and $3.3 million for unfunded lending-related commitments) as of September 30, 2020.

To determine the ACL as of September 30, 2020, Customers utilized the Moody's September 2020 Baseline forecast to generate its modelled expected losses to reflect management's reasonable expectations of current and future economic conditions. The Baseline forecast assumed improvement in forecasts of macroeconomic conditions compared to the second quarter forecast of macroeconomic conditions used by Customers; the Federal Reserve maintaining a target range for the fed funds rate at 0.00% to 0.25% into 2023; the FRB's emergency lending facilities remaining operational through the end of 2020, with the tapering of quantitative easing not beginning until 2021; and an additional $1.5 trillion of stimulus from the federal government, which is now anticipated before the end of 2020. Customers continues to monitor the impact of the COVID-19 pandemic and related policy measures on the economy and, if the depth of the recession or pace of the expected recovery is worse than expected, further meaningful provisions for credit losses could be required.

There is no certainty that Customers' ACL will be appropriate over time to cover losses in our portfolio as economic and market conditions may ultimately differ from our reasonable and supportable forecast. Additionally, events adversely affecting specific customers, industries, or Customers' markets, such as the current COVID-19 pandemic, could severely impact our current expectations. If the credit quality of Customers' customer base materially deteriorates or the risk profile of a market, industry, or group of customers changes materially, Customers' net income and capital could be materially adversely affected which, in turn could have a material adverse effect on Customers' financial condition and results of operations. The extent to which the current COVID-19 pandemic has and will continue to negatively impact Customers' businesses, financial condition, liquidity and results will depend on future developments, which are highly uncertain and cannot be forecasted with precision at this time.

Customers reported net income available to common shareholders of $47.1 million and $65.7 million for the three and nine months ended September 30, 2020, respectively, compared to net income available to common shareholders of $23.5 million and $41.0 million for the three and nine months ended September 30, 2019, respectively. Factors contributing to the change in net income available to common shareholders for the three and nine months ended September 30, 2020 compared to the three and nine months ended September 30, 2019 were as follows:

Net interest income

Net interest income increased $31.7 million for the three months ended September 30, 2020 compared to the three months ended September 30, 2019 as average interest-earning assets increased by $6.5 billion, partially offset by a 33 basis point decline in NIM to 2.50% for the three months ended September 30, 2020 from 2.83% for the three months ended September 30, 2019. The decline in NIM resulted from the Federal Reserve interest rate cuts of 225 basis points beginning in August 2019 and the shift in the mix of interest-earning assets and interest-bearing liabilities drove a 147 basis point decline in the yield on interest-earning assets and a 144 basis point decline in the cost of interest-bearing liabilities for the three months ended September 30, 2020. The largest shift in the mix of interest-earning assets and interest-bearing liabilities was $5.0 billion ($4.9 billion average balance) of PPP loans yielding 1.97% and related PPPLF borrowings of $4.8 billion ($4.5 billion average balance) costing 0.35%. Customers' total cost of funds, including non-interest bearing deposits was 0.78% and 2.00% for the three months ended September 30, 2020 and 2019, respectively.

Net interest income increased $81.0 million for the nine months ended September 30, 2020 compared to the nine months ended September 30, 2019 as average interest-earning assets increased by $4.1 billion, partially offset by a one basis point decline in NIM to 2.68% for the nine months ended September 30, 2020 from 2.69% for the nine months ended September 30, 2019. The decline in NIM resulted from the Federal Reserve interest rate cuts of 225 basis points beginning in August 2019 and the shift in the mix of interest-earning assets and interest-bearing liabilities drove a 86 basis point decline in the yield on interest-earning assets and a 109 basis point decline in the cost of interest-bearing liabilities for the nine months ended September 30, 2020. The largest shift in the mix of interest-earning assets and interest-bearing liabilities was the origination of $5.0 billion ($2.6 billion average balance) in PPP loans yielding 1.88% and related PPPLF borrowings of $4.8 billion ($1.8 billion average balance) costing 0.35%. Customers' total cost of funds, including non-interest bearing deposits was 1.08% and 2.00% for the nine months ended September 30, 2020 and 2019, respectively.

Provision for credit losses

The $8.5 million increase in the provision for credit losses for the three months ended September 30, 2020 compared to the three months ended September 30, 2019, reflects Customers' adoption of CECL and the impact of COVID-19. Upon adoption of the CECL standard on January 1, 2020, the allowance for credit losses for loans and leases and off-balance sheet credit exposures increased by $79.8 million and $3.4 million, respectively. The allowance for credit losses on off-balance sheet credit exposures is presented within accrued interest payable and other liabilities in the consolidated balance sheet and the related provision is presented as part of other non-interest expense on the consolidated income statement. The allowance for credit losses on loans and leases held for investment, represented 2.02% of total loans and leases receivable, excluding PPP loans (non-GAAP measure, please refer to the non-GAAP reconciliation within Loans and Leases - Asset Quality), at September 30, 2020, compared to 0.70% at September 30, 2019. Net charge-offs for the three months ended September 30, 2020 were $17.3 million, or 45 basis points of average loans and leases on an annualized basis, compared to net charge-offs of $1.8 million, or seven basis points on an annualized basis, for the three months ended September 30, 2019. The increase in net charge-offs for the three months ended September 30, 2020, compared to the three months ended September 30, 2019, was primarily due to a partial charge-off of $9.6 million for one commercial real estate collateral dependent loan during the three months ended September 30, 2020 and an increase in charge-offs of installment loans, coinciding with the growth of the portfolio year-over-year.

The $51.1 million increase in the provision for credit losses for the nine months ended September 30, 2020 compared to the nine months ended September 30, 2019, reflects Customers' adoption of CECL and the impact of COVID-19. Net charge-offs for the nine months ended September 30, 2020 were $46.3 million, or 49 basis points of average loans and leases on an annualized basis, compared to net charge-offs of $3.5 million, or five basis points on an annualized basis, for the nine months ended September 30, 2019. The increase in net charge-offs for the nine months ended September 30, 2020, compared to the nine months ended September 30, 2019, was primarily due to partial charge-offs of $25.2 million for two commercial real estate collateral dependent loans during the nine months ended September 30, 2020 and an increase in charge-offs of installment loans, coinciding with the growth of the portfolio year-over-year.

Non-interest income

The $10.4 million increase in non-interest income for the three months ended September 30, 2020 compared to the three months ended September 30, 2019 primarily resulted from increases of $10.7 million in gain on sale of investment securities, $1.4 million in commercial lease income, $1.2 million in mortgage warehouse transactional fees, and $0.7 million in mortgage banking income. These increases were offset in part by decreases of $2.8 million in interchange and card revenue and $1.1 million in unrealized gain on investment securities for the three months ended September 30, 2020 compared to the three months ended September 30, 2019.

The $22.8 million increase in non-interest income for the nine months ended September 30, 2020 compared to the nine months ended September 30, 2019 primarily resulted from increases of $19.0 million in gain on sale of investment securities, $5.1 million in commercial lease income, $2.7 million in mortgage warehouse transactional fees, and $1.0 million in deposit fees, along with a $7.5 million reduction in loss upon acquisition of interest-only GNMA securities. These increases were offset in part by decreases of $7.2 million in other non-interest income and $5.1 million in interchange and card revenue for the nine months ended September 30, 2020 compared to the nine months ended September 30, 2019.

Non-interest expense

The $6.0 million increase in non-interest expense for the three months ended September 30, 2020 compared to the three months ended September 30, 2019 primarily resulted from increases of $5.5 million in salaries and employee benefits, $4.6 million in FDIC assessments, non-income taxes and regulatory fees, $4.5 million in technology, communication and bank operations, $1.2 million in commercial lease depreciation, $1.0 million in merger and acquisition related expenses, and $0.4 million in loan workout. These increases were offset in part by decreases of $6.1 million in other non-interest expense, $2.8 million in provision for operating losses, $1.1 million in professional services, and $1.0 million in advertising and promotion for the three months ended September 30, 2020 compared to the three months ended September 30, 2019.

The $22.4 million increase in non-interest expense for the nine months ended September 30, 2020 compared to the nine months ended September 30, 2019 primarily resulted from increases of $12.3 million in salaries and employee benefits, $6.5 million in technology, communication and bank operations, $5.7 million in FDIC assessments, non-income taxes and regulatory fees, $4.1 million in commercial lease depreciation, $1.6 million in loan workout, and $1.1 million in merger and acquisition related expenses. These increases were offset in part by decreases of $5.1 million in provision for operating losses and $3.7 million in other non-interest expense for the nine months ended September 30, 2020 compared to the nine months ended September 30, 2019.

Income tax expense

Customers' effective tax rate was 19.45% for the three months ended September 30, 2020 compared to 22.86% for the three months ended September 30, 2019. The decrease in the effective tax rate primarily resulted from an increase in the estimated annual benefit of investment tax credits for the three months ended September 30, 2020, compared to the three months ended September 30, 2019.

Customers' effective tax rate was 21.70% for the nine months ended September 30, 2020 compared to 22.85% for the nine months ended September 30, 2019. The decrease in the effective tax rate primarily resulted from an increase in the estimated annual benefit of investment tax credits for the nine months ended September 30, 2020, compared to the nine months ended September 30, 2019.

Preferred stock dividends

Preferred stock dividends were $3.4 million and $3.6 million for the three months ended September 30, 2020 and 2019, respectively. There were no changes to the amount of preferred stock outstanding during the three months ended September 30, 2020 and 2019. On June 15, 2020, the Series C preferred stock became floating at three-month LIBOR plus 5.300%, or 5.60%, compared to a fixed rate of 7.00%.

Preferred stock dividends were $10.6 million and $10.8 million for the nine months ended September 30, 2020 and 2019, respectively. There were no changes to the amount of preferred stock outstanding during the nine months ended September 30, 2020 and 2019. On June 15, 2020, the Series C preferred stock became floating at three-month LIBOR plus 5.300%, or 5.60%, compared to a fixed rate of 7.00%.

NET INTEREST INCOME

Net interest income (the difference between the interest earned on loans and leases, investments and interest-earning deposits with banks, and interest paid on deposits, borrowed funds and subordinated debt) is the primary source of Customers' earnings. The following tables summarize Customers' net interest income, related interest spread, net interest margin and the dollar amount of changes in interest income and interest expense for the major categories of interest-earning assets and interest-bearing liabilities for the three and nine months ended September 30, 2020 and 2019. Information is provided for each category of interest-earning assets and interest-bearing liabilities with respect to (i) changes attributable to volume (i.e., changes in average balances multiplied by the prior-period average rate) and (ii) changes attributable to rate (i.e., changes in average rate multiplied by prior-period average balances). For purposes of this table, changes attributable to both rate and volume which cannot be segregated have been allocated proportionately to the change due to volume and the change due to rate.

Net interest income increased $31.7 million for the three months ended September 30, 2020 compared to the three months ended September 30, 2019 as average interest-earning assets increased by $6.5 billion, primarily related to PPP loan originations, increases in installment loans, commercial loans to mortgage companies, commercial and industrial loans, investment securities, and interest-earning deposits, partially offset by a 33 basis point decline in NIM to 2.50% for the three months ended September 30, 2020 from 2.83% for the three months ended September 30, 2019 resulting from the Federal Reserve interest rate cuts of 225 basis points beginning in August 2019 and the shift in the mix of interest-earning assets and interest-bearing liabilities drove a 147 basis point decline in the yield on interest-earning assets and a 144 basis point decline in the cost of interest-bearing liabilities for the three months ended September 30, 2020. The largest shift in the mix of interest-earning assets and interest-bearing liabilities was $5.0 billion ($4.9 billion average balance) of PPP loans yielding 1.97% and related PPPLF borrowings of $4.8 billion ($4.5 billion average balance) costing 0.35%. Customers' total cost of funds, including non-interest bearing deposits was 0.78% and 2.00% for the three months ended September 30, 2020 and 2019, respectively.

(6)Non-GAAP tax-equivalent basis, as described in note (5) for the nine months ended September 30, 2020 and 2019, excluding net interest income from PPP loans and related borrowings, along with the related PPP loan balances and PPP fees receivable from interest-earning assets. Management uses non-GAAP measures to present historical periods comparable to the current period presentation.

Net interest income increased $81.0 million for the nine months ended September 30, 2020 compared to the nine months ended September 30, 2019 as average interest-earning assets increased by $4.1 billion, primarily related to PPP loan originations, increases in installment loans, commercial loans to mortgage companies, commercial and industrial loans, investment securities, and interest earning deposits, partially offset by a 1 basis point decline in NIM to 2.68% for the nine months ended September 30, 2020 from 2.69% for the nine months ended September 30, 2019, resulting from the Federal Reserve interest rate cuts of 225 basis points beginning in August 2019 and the shift in the mix of interest-earning assets drove a 86 basis point decline in the yield on interest-earnings assets and an 109 basis point decline in the cost of interest-bearing liabilities for the nine months ended September 30, 2020. The largest shift in the mix of interest-earning assets and interest-bearing liabilities was the origination of $5.0 billion ($2.6 billion average balance) in PPP loans yielding 1.88% and related PPPLF borrowings of $4.8 billion ($1.8 billion average balance) costing 0.35%. Customers' total cost of funds, including non-interest bearing deposits was 1.08% and 2.00% for the nine months ended September 30, 2020 and 2019, respectively.

Customers’ net interest margin tables contain non-GAAP financial measures calculated using non-GAAP amounts. These measures include net interest margin tax equivalent and net interest margin tax equivalent, excluding PPP loans. Management uses these non-GAAP measures to present the current period presentation to historical periods in prior filings. In addition, management believes the use of these non-GAAP measures provides additional clarity when assessing Customers' financial results. These disclosures should not be viewed as substitutes for results determined to be in accordance with U.S. GAAP, nor are they necessarily comparable to non-GAAP performance measures that may be presented by other entities.

PROVISION FOR CREDIT LOSSES

The provision for credit losses is a charge to earnings to maintain the allowance for credit losses at a level consistent with management’s assessment of expected lifetime losses in the loan and lease portfolio at the balance sheet date. During first quarter 2020, Customers adopted ASU 2016-13. Upon adoption, the allowance for credit losses for loans and leases and lending-related unfunded commitments increased by $79.8 million and $3.4 million, respectively, with the after-tax cumulative effect recorded to retained earnings. Customers recorded $13.0 million and a credit of $0.5 million of provision for credit losses for loans and leases and lending-related commitments, respectively, for the three months ended September 30, 2020 utilizing the CECL methodology. The additional provision for credit losses during the three months ended September 30, 2020 resulted primarily from net charge-offs and portfolio growth, partially offset by

changes in management's economic forecast since June 30, 2020, due to improved forecasts of macroeconomic conditions. Customers recorded $65.7 million and a $0.1 million credit for provision for credit losses for loans and leases and lending-related commitments, respectively, for the nine months ended September 30, 2020. The increase resulted primarily from the impact of reserve build for the COVID-19 pandemic, portfolio growth, and net-charge-offs.

Interchange and card revenue

The $2.8 million decrease in interchange and card revenue for the three months ended September 30, 2020 compared to the three months ended September 30, 2019 primarily resulted from Customers becoming subject to the Federal Reserve's regulation limits on interchange fees for banks over $10 billion in assets beginning on July 1, 2020.

The $5.1 million decrease in interchange and card revenue for the nine months ended September 30, 2020 compared to the nine months ended September 30, 2019 primarily resulted from Customers becoming subject to the Federal Reserve's regulation limits on interchange fees for banks over $10 billion in assets beginning on July 1, 2020 and lower activity volumes at the BankMobile segment, primarily due to COVID-19.

Deposit fees

The $0.2 million decrease in deposit fees for the three months ended September 30, 2020 compared to the three months ended September 30, 2019 primarily resulted from lower activity volumes.

The $1.0 million increase in deposit fees for the nine months ended September 30, 2020 compared to the nine months ended September 30, 2019 primarily resulted from an increase in service charges on certain deposit accounts relating to a change in the fee structure at the BankMobile segment, partially offset by lower activity volumes.

Commercial lease income

Commercial lease income represents income earned on commercial operating leases originated by Customers' Equipment Finance Group in which Customers is the lessor. The $1.4 million increase in commercial lease income for the three months ended September 30, 2020 compared to the three months ended September 30, 2019 primarily resulted from the continued growth of Customers' equipment finance business.

Table of Contents

The $5.1 million increase in commercial lease income for the nine months ended September 30, 2020 compared to the nine months ended September 30, 2019 primarily resulted from the continued growth of Customers' equipment finance business.

Mortgage warehouse transactional fees

The $1.2 million increase in mortgage warehouse transactional fees for the three months ended September 30, 2020 compared to the three months ended September 30, 2019 primarily resulted from an increase in refinancing activity driven by the decline in market interest rates during the three months ended September 30, 2020 compared to the three months ended September 30, 2019.

The $2.7 million increase in mortgage warehouse transactional fees for the nine months ended September 30, 2020 compared to the nine months ended September 30, 2019 primarily resulted from an increase in refinancing activity driven by the decline in market interest rates during the nine months ended September 30, 2020 compared to the nine months ended September 30, 2019.

Mortgage banking income

The $0.7 million increase in mortgage banking income for the three months ended September 30, 2020 compared to the three months ended September 30, 2019 primarily resulted from an increase in unrealized gains on derivatives and gains on sales of mortgage servicing rights during the three months ended September 30, 2020 compared to the three months ended September 30, 2019.

The $0.6 million increase in mortgage banking income for the nine months ended September 30, 2020 compared to the nine months ended September 30, 2019 primarily resulted from an increase in unrealized gains on derivatives and gains on sales of mortgage servicing rights during the nine months ended September 30, 2020 compared to the nine months ended September 30, 2019.

Loss on acquisition of interest-only GNMA securities

The $7.5 million decrease in loss on acquisition of interest-only GNMA for the nine months ended September 30, 2020 compared to the nine months ended September 30, 2019 resulted from a mortgage warehouse customer that unexpectedly ceased operations in the second quarter 2019. Customers took possession of the interest-only GNMA securities that served as the primary collateral for loans made to this mortgage warehouse customer. The shortfall in the fair value of the interest-only GNMA securities upon acquisition resulted in a write-down of $7.5 million in second quarter 2019. Customers views this as an isolated event that is not indicative of the overall credit quality of the mortgage warehouse portfolio. There are no other loans in the mortgage warehouse portfolio secured by interest-only securities. These securities were sold for $15.4 million with a realized gain of $1.0 million during the three months ended September 30, 2020.

Gain (loss) on sale of investment securities

The $10.7 million increase in gain (loss) on sale of investment securities for the three months ended September 30, 2020 compared to the three months ended September 30, 2019 reflects the gains realized from the sale of $58.4 million of agency-guaranteed mortgage-backed securities and $70.0 million in corporate notes during the three months ended September 30, 2020.

The $19.0 million increase in gain (loss) on sale of investment securities for the nine months ended September 30, 2020 compared to the nine months ended September 30, 2019 reflects the gains realized from the sale of $158.9 million of agency-guaranteed mortgage-backed securities, $70.0 million in corporate notes, $30.0 million of corporate bonds, and $6.3 million in non-agency-guaranteed collateralized mortgage obligations during the nine months ended September 30, 2020.

Unrealized gain (loss) on investment securities

The $1.1 million decrease in unrealized gain (loss) on investment securities for the three months ended September 30, 2020 compared to the three months ended September 30, 2019 reflects a decline in the unrealized gain of equity securities issued by a foreign entity for the three months ended September 30, 2020.

The $0.9 million decrease in unrealized gain (loss) on investment securities for the nine months ended September 30, 2020 compared to the nine months ended September 30, 2019 reflects a decline in the unrealized gain of equity securities issued by a foreign entity for the nine months ended September 30, 2020.

Other non-interest income

The $0.3 million increase in other non-interest income for the three months ended September 30, 2020 compared to the three months ended September 30, 2019 primarily resulted from a net positive mark-to-market derivative valuation adjustment of $1.0 million, due to market interest rates, partially offset by a decrease of $0.5 million in swap premiums.

65

Table of Contents

The $7.2 million decrease in other non-interest income for the nine months ended September 30, 2020 compared to the nine months ended September 30, 2019 primarily resulted from a net negative derivative valuation adjustment of $5.2 million, due to changes in market interest rates and a negative credit valuation adjustment from an interest rate swap associated with a non-performing borrower in second quarter 2020, and a market value adjustment loss on one loan held for sale of $1.5 million in second quarter 2020.

Salaries and employee benefits

The $5.5 million increase in salaries and employee benefits for the three months ended September 30, 2020 compared to the three months ended September 30, 2019 primarily resulted from an increase in average full-time equivalent team members needed for future growth, annual merit increases, and an increase in incentive accruals tied to Customers' overall performance.

The $12.3 million increase in salaries and employee benefits for the nine months ended September 30, 2020 compared to the nine months ended September 30, 2019 primarily resulted from an increase in average full-time equivalent team members needed for future growth, annual merit increases, and an increase in incentive accruals tied to Customers' overall performance.

Technology, communication, and bank operations

The $4.5 million increase in technology, communication, and bank operations expense for the three months ended September 30, 2020 compared to the three months ended September 30, 2019 primarily resulted from the continued investment in Customers' white label partnership and digital transformation efforts.

The $6.5 million increase in technology, communication, and bank operations expense for the nine months ended September 30, 2020 compared to the nine months ended September 30, 2019 primarily resulted from the continued investment in Customers' white label partnership and digital transformation efforts.

Professional services

The $1.1 million decrease in professional services for the three months ended September 30, 2020 compared to the three months ended September 30, 2019 primarily resulted from management's continued efforts to monitor and control expenses.

66

Table of Contents

The $0.8 million increase in professional services for the nine months ended September 30, 2020 compared to the nine months ended September 30, 2019 primarily resulted from consulting services associated with supporting Customers' white label partnership and digital transformation efforts, partially offset by management's continued efforts to monitor and control expenses.

Commercial lease depreciation

The $1.2 million increase in commercial lease depreciation for the three months ended September 30, 2020 compared to the three months ended September 30, 2019 primarily resulted from the continued growth of the operating lease arrangements originated by Customers' Equipment Finance Group in which Customers is the lessor.

The $4.1 million increase in commercial lease depreciation for the nine months ended September 30, 2020 compared to the nine months ended September 30, 2019 primarily resulted from the continued growth of the operating lease arrangements originated by Customers' Equipment Finance Group in which Customers is the lessor.

FDIC assessments, non-income taxes, and regulatory fees

The $4.6 million increase in FDIC assessments, non-income taxes, and regulatory fees for the three months ended September 30, 2020 compared to the three months ended September 30, 2019 primarily resulted from an increase in FDIC assessment rates resulting from management's decision to grow the balance sheet beyond $10 billion in assets, as higher premiums become applicable, and the temporary utilization of brokered deposits to fund PPP loans.

The $5.7 million increase in FDIC assessments, non-income taxes, and regulatory fees for the nine months ended September 30, 2020 compared to the nine months ended September 30, 2019 primarily resulted from an increase in FDIC assessment rates resulting from management's decision to grow the balance sheet beyond $10 billion in assets, as higher premiums become applicable, and the temporary utilization of brokered deposits to fund PPP loans.

Provision for operating losses

The provision for operating losses primarily consists of losses resulting from fraud or theft-based transactions that have generally been disputed by deposit account holders. The $2.8 million decrease in provision for operating losses for the three months ended September 30, 2020 compared to the three months ended September 30, 2019 primarily resulted from an internet-based organized crime ring that was identified during the three months ended September 30, 2019 and initiatives implemented by management to reduce fraud and theft-based losses during the three months ended September 30, 2020.

The $5.1 million decrease in provision for operating losses for the nine months ended September 30, 2020 compared to the nine months ended September 30, 2019 primarily resulted from an internet-based organized crime ring that was identified during the three months ended September 30, 2019 and initiatives implemented by management to reduce fraud and theft-based losses during the nine months ended September 30, 2020.

The ACL maintained for loans and leases receivable (excluding loans held for sale and loans receivable, mortgage warehouse, at fair value and PPP loans) was $155.6 million, or 2.02% of loans and leases receivable, excluding PPP loans, at September 30, 2020 and $56.4 million, or 0.77% of loans and leases receivable, at December 31, 2019. Net charge-offs were $17.3 million for the three months ended September 30, 2020, an increase of $15.5 million compared to the same period in 2019. The increase in the ACL resulted primarily from the impact of reserve build for the COVID-19 pandemic, mostly attributable to the commercial real estate non-owner occupied and installment portfolios, and portfolio growth. Commercial real estate non-owner occupied charge-offs were attributable to the partial charge-off of two collateral dependent loans, which are not indicative of the overall commercial real estate portfolio. Installment charge-offs were attributable to originated and purchased unsecured consumer loans through arrangements with fintech companies and other market place lenders.

All commercial loans, with the exception of PPP loans and commercial mortgage warehouse loans, which are reported at fair value, are assigned internal credit-risk ratings, based upon an assessment of the borrower, the structure of the transaction and the available collateral and/or guarantees. All loans and leases are monitored regularly by the responsible officer, and the risk ratings are adjusted when considered appropriate. The risk assessment allows management to identify problem loans and leases timely. Management considers a variety of factors and recognizes the inherent risk of loss that always exists in the lending process. Management uses a disciplined methodology to estimate an appropriate level of ACL.

SIGNIFICANT ACCOUNTING POLICIES AND BASIS OF PRESENTATION to Customers' audited financial statements in its 2019 Form 10-K for further discussion on management's prior incurred loss methodology for estimating the ALLL.

Approximately 67% of Customers' commercial real estate, commercial and residential construction, consumer residential and commercial and industrial loan types have real estate as collateral (collectively, “the real estate portfolio”), primarily in the form of a first lien position. Current appraisals providing current value estimates of the property are received when Customers' credit group determines that the facts and circumstances have significantly changed since the date of the last appraisal, including that real estate values have deteriorated. The credit committee and loan officers review loans that are 15 or more days delinquent and all non-accrual loans on a periodic basis. In addition, loans where the loan officers have identified a “borrower of interest” are discussed to determine if additional analysis is necessary to apply the risk-rating criteria properly. The risk ratings for the real estate loan portfolio are determined based upon the current information available, including but not limited to discussions with the borrower, updated financial information, economic conditions within the geographic area and other factors that may affect the cash flow of the loan. If a loan is individually evaluated for impairment, the collateral value or discounted cash flow analysis is generally used to determine the estimated fair value of the underlying collateral, net of estimated selling costs, and compared to the outstanding loan balance to determine the amount of reserve necessary, if any. Appraisals used in this evaluation process are typically less than two years aged. For loans where real estate is not the primary source of collateral, updated financial information is obtained, including accounts receivable and inventory aging reports and relevant supplemental financial data to estimate the fair value of the loan, net of estimated selling costs, and compared to the outstanding loan balance to estimate the required reserve.

These impairment measurements are inherently subjective as they require material estimates, including, among others, estimates of property values in appraisals, the amounts and timing of expected future cash flows on individual loans, and general considerations for historical loss experience, economic conditions, uncertainties in estimating losses and inherent risks in the various credit portfolios, all of which require judgment and may be susceptible to significant change over time and as a result of changing economic conditions or other factors. Pursuant to ASC 326, individually assessed loans, consisting primarily of non-accrual and restructured loans, are considered in the methodology for determining the ACL. Individually assessed loans are generally evaluated based on the expected future cash flows or the fair value of the underlying collateral (less estimated costs to sell) if principal repayment is expected to come from the operation or sale of such collateral. Shortfalls in the underlying collateral value for loans or leases determined to be collateral dependent are charged off immediately. Subsequent to an appraisal or other fair value estimate, management will assess whether there was a further decline in the value of the collateral based on changes in market conditions or property use that would require additional impairment to be recorded to reflect the particular situation, thereby increasing the ACL on loans and leases.

Asset Quality

Customers segments the loan and lease receivables by loan product or other characteristic generally defining a shared characteristic with other loans in the same group. Charge-offs from originated and acquired loans and leases are absorbed by the ACL. 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 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. At September 30, 2020, commercial and consumer deferments related to COVID-19 were $79 million and $25 million, respectively. The schedule that follows includes both loans held for sale and loans held for investment. As of September 30, 2020, Customers had $198.5 million of pending commercial loan deferment requests.

Total shareholders' equity	$	1,051,491	$	1,052,795	$	(1,304)	(0.1)	%

Shareholders’ equity decreased $1.3 million, or 0.1%, to $1.1 billion at September 30, 2020 when compared to shareholders' equity of $1.1 billion at December 31, 2019. The decrease primarily resulted from an increase of $14.5 million in accumulated other comprehensive loss, net, partially offset by increases of $8.7 million in additional paid in capital and $4.2 million in retained earnings.

The increase in accumulated other comprehensive loss, net primarily resulted from a decline in the fair value of cash flow hedges due to changes in market interest rates during the nine months ended September 30, 2020, partially offset by an increase in the fair value of available for sale debt securities due to the timing of purchases and changes in market interest rates during the nine months ended September 30, 2020. The increase in additional paid in capital resulted primarily from the issuance of common stock under share-based compensation arrangements for the nine months ended September 30, 2020. The increase in retained earnings primarily resulted from net income of $76.3 million, partially offset by the adoption of CECL on January 1, 2020, which reduced retained earnings by $61.5 million, and $10.6 million in preferred stock dividends.

LIQUIDITY AND CAPITAL RESOURCES

Liquidity for a financial institution is a measure of that institution’s ability to meet depositors’ needs for funds, to satisfy or fund loan and lease commitments, and for other operating purposes.  Ensuring adequate liquidity is an objective of the asset/liability management process. Customers coordinates its management of liquidity with its interest rate sensitivity and capital position, and strives to maintain a strong liquidity position.

Customers' investment portfolio provides periodic cash flows through regular maturities and amortization and can be used as collateral to secure additional funding. Customers' principal sources of funds are deposits, borrowings, principal and interest payments on loans and leases, other funds from operations, and proceeds from common and preferred stock issuances.  Borrowing arrangements are maintained with the FHLB and the FRB to meet short-term liquidity needs.  Longer-term borrowing arrangements are also maintained with the FHLB and FRB. As of September 30, 2020, Customers' borrowing capacity with the FHLB was $2.9 billion, of which $0.9 billion was utilized in borrowings and $1.1 billion of available capacity was utilized to collateralize state and municipal deposits. As of December 31, 2019, Customers' borrowing capacity with the FHLB was $3.4 billion, of which $0.9 billion was utilized in borrowings and $1.4 billion of available capacity was utilized to collateralize state and municipal deposits.

CAPITAL ADEQUACY

The Bank and Customers Bancorp are subject to various regulatory capital requirements administered by federal banking agencies. Failure to meet 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 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.

In April 2020, the U.S. federal banking regulatory agencies issued an interim final rule that permits banks to exclude the impact of participating in the SBA PPP program in their regulatory capital ratios. Specifically, PPP loans are zero percent risk weighted and a bank can exclude all PPP loans pledged as collateral to the PPPLF from its average total consolidated assets for purposes of calculating the Tier 1 capital to average assets ratio (i.e. leverage ratio). Customers applied this regulatory guidance in the calculation of its regulatory capital ratios presented below.

Quantitative measures established by regulation to ensure capital adequacy require the Bank and the Bancorp to maintain minimum amounts and ratios (set forth in the following table) of common equity Tier 1, Tier 1, and total capital to risk-weighted assets, and Tier 1 capital to average assets (as defined in the regulations). At September 30, 2020 and December 31, 2019, the Bank and the Bancorp met all capital adequacy 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 set forth in the following table:

The capital ratios above reflect the capital requirements under "Basel III" adopted effective first quarter 2015 and the capital conservation buffer phased in beginning January 1, 2016. Failure to maintain the required capital conservation buffer will result in limitations on capital distributions and on discretionary bonuses to executive officers. As of September 30, 2020, the Bank and Customers Bancorp were in compliance with the Basel III requirements. See "NOTE 10 - REGULATORY CAPITAL" to Customers' unaudited financial statements for additional discussion regarding regulatory capital requirements.

OFF-BALANCE SHEET ARRANGEMENTS

Customers is involved with financial instruments and other commitments with off-balance sheet risks.  Financial instruments with off-balance sheet risks are incurred in the normal course of business to meet the financing needs of the Bank's customers.  These financial instruments include commitments to extend credit, including unused portions of lines of credit, and standby letters of credit.  Those instruments involve, to varying degrees, elements of credit risk in excess of the amount recognized on the balance sheet.

With commitments to extend credit, exposure to credit loss in the event of non-performance by the other party to the financial instrument is represented by the contractual amount of those instruments.  The same credit policies are used in making commitments and

82

Table of Contents

conditional obligations as for on-balance sheet instruments.  Because they involve credit risk similar to extending a loan and lease, these financial instruments are subject to the Bank’s credit policy and other underwriting standards.

As of September 30, 2020 and December 31, 2019, the following off-balance sheet commitments, financial instruments and other arrangements were outstanding:

(amounts in thousands)	September 30, 2020		December 31, 2019
Commitments to fund loans and leases	$	246,036	$	261,902
Unfunded commitments to fund mortgage warehouse loans	1,303,981		1,378,364
Unfunded commitments under lines of credit and credit cards	917,305		1,065,474
Letters of credit	27,580		48,856
Other unused commitments	2,167		2,736

Commitments to fund loans and leases, unfunded commitments to fund mortgage warehouse loans, unfunded commitments under lines of credit, letters of credit, and credit cards are agreements to extend credit to or for the benefit of a customer in the ordinary course of the Bank's business.

Commitments to fund loans and leases and unfunded commitments under lines of credit may be obligations of the Bank as long as there is no violation of any condition established in the contract.  Because many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements.  Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee.  The Bank evaluates each customer’s creditworthiness on a case-by-case basis.  The amount of collateral obtained, if the Bank deems it necessary upon extension of credit, is based upon management’s credit evaluation.  Collateral held varies but may include personal or commercial real estate, accounts receivable, inventory and equipment.

Mortgage warehouse loan commitments are agreements to fund the pipelines of mortgage banking businesses from closing of individual mortgage loans until their sale into the secondary market. Most of the individual mortgage loans are insured or guaranteed by the U.S. government through one of its programs such as FHA, VA, or are conventional loans eligible for sale to Fannie Mae and Freddie Mac. These commitments generally fluctuate monthly based on changes in interest rates, refinance activity, new home sales and laws and regulation.

Outstanding letters of credit written are conditional commitments issued by the Bank to guarantee the performance of a customer to a third party. Letters of credit may obligate the Bank to fund draws under those letters of credit whether or not a customer continues to meet the conditions of the extension of credit. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan and lease facilities to customers.

Effect of Government Monetary Policies

Our earnings are and will be affected by domestic economic conditions and the monetary and fiscal policies of the United States government and its agencies. An important function of the Federal Reserve Board is to regulate the money supply and interest rates. Among the instruments used to implement those objectives are open market operations in United States government securities and changes in reserve requirements against member bank deposits. These instruments are used in varying combinations to influence overall growth and distribution of bank loans and leases, investments, and deposits, and their use may also affect rates charged on loans and leases or paid for deposits.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Interest Rate Sensitivity

The largest component of Customers' net income is net interest income, and the majority of its financial instruments are interest rate sensitive assets and liabilities with various term structures and maturities.  One of the primary objectives of management is to optimize net interest income while minimizing interest rate risk.  Interest rate risk is derived from timing differences in the repricing of assets and liabilities, loan prepayments, deposit withdrawals and differences in lending and funding rates.  Customers' asset/liability committee actively seeks to monitor and control the mix of interest rate sensitive assets and interest rate sensitive liabilities.

Customers uses two complementary methods to analyze and measure interest rate sensitivity as part of the overall management of interest rate risk; they are income scenario modeling and estimates of EVE.  The combination of these two methods provides a reasonably comprehensive summary of the levels of interest rate risk of Customers' exposure to time factors and changes in interest rate environments.

83

Table of Contents

Income scenario modeling is used to measure interest rate sensitivity and manage interest rate risk.  Income scenario considers not only the impact of changing market interest rates upon forecasted net interest income but also other factors such as yield-curve relationships, the volume and mix of assets and liabilities, customer preferences and general market conditions.

Through the use of income scenario modeling, Customers has estimated the net interest income for the periods ending September 30, 2021 and December 31, 2020, based upon the assets, liabilities and off-balance sheet financial instruments in existence at September 30, 2020 and December 31, 2019. Customers has also estimated changes to that estimated net interest income based upon interest rates rising or falling immediately (“rate shocks”). For upward rate shocks modeling a rising rate environment at September 30, 2020, current market interest rates were increased immediately by 100, 200, and 300 basis points. For downward rate shocks modeling a falling rate environment, current market rates were only decreased immediately by 100 basis points due to the limitations of the current low interest rate environment that renders the Down 200 and Down 300 rate shocks impractical. The downward rate shocks modeled will be revisited in the future if necessary and will be contingent upon additional Federal Reserve interest rate hikes. The following table reflects the estimated percentage change in estimated net interest income for the periods ending September 30, 2020 and December 31, 2019, resulting from changes in interest rates.

Net change in net interest income

	% Change
Rate Shocks	September 30, 2020	December 31, 2019
Up 3%	8.4%	3.3%
Up 2%	5.9%	2.7%
Up 1%	3.2%	1.6%
Down 1%	1.1%	(1.9)%

The net changes in net interest income in all scenarios are within Customers Bank's interest rate risk policy guidelines.

EVE estimates the discounted present value of asset and liability cash flows. Discount rates are based upon market prices for comparable assets and liabilities. Upward and downward rate shocks are used to measure volatility of EVE in relation to a constant rate environment. For upward rate shocks modeling a rising rate environment at September 30, 2020, current market interest rates were only increased immediately by 100, 200, and 300 basis points. For downward rate shocks modeling a falling rate environment, current market rates were decreased immediately by 100 basis points due to the limitations of the current low interest rate environment that renders the Down 200 and Down 300 rate shocks impractical. The downward rate shocks modeled will be revisited in the future if necessary and will be contingent upon additional Federal Reserve interest rate hikes. This method of measurement primarily evaluates the longer term repricing risks and options in Customers Bank’s balance sheet. The following table reflects the estimated EVE at risk and the ratio of EVE to EVE adjusted assets at September 30, 2020 and December 31, 2019, resulting from shocks to interest rates.

	From base
Rate Shocks	September 30, 2020	December 31, 2019
Up 3%	(15.6)%	(5.6)%
Up 2%	(9.3)%	(2.0)%
Up 1%	(4.3)%	(1.0)%
Down 1%	(1.4)%	(1.1)%

The net changes in EVE in all scenarios are within Customers Bank's interest rate risk policy guidelines.

Management believes that the assumptions and combination of methods utilized in evaluating estimated net interest income are reasonable. However, the interest rate sensitivity of our assets, liabilities and off-balance sheet financial instruments, as well as the estimated effect of changes in interest rates on estimated net interest income, could vary substantially if different assumptions are used or actual experience differs from the assumptions used in the model.

Item 4. Controls and Procedures

(a) Management's Evaluation of Disclosure Controls and Procedures. As of the end of the period covered by this report, Customers Bancorp carried out an evaluation, under the supervision and with the participation of Customers Bancorp’s management, including Customers Bancorp’s Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of Customers Bancorp’s disclosure controls and procedures as defined in the Exchange Act Rules 13a-15(e) and 15d-15(e). Based upon the evaluation, the Chief Executive Officer and Chief Financial Officer concluded that Customers Bancorp’s disclosure controls and procedures were effective as of September 30, 2020.

(b) Changes in Internal Control Over Financial Reporting. During the quarter ended September 30, 2020, there have been no changes in Customers Bancorp's internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, Customers Bancorp's internal control over financial reporting.

The emergence of the COVID-19 pandemic during first quarter 2020 necessitated the execution of several Customers Bancorp contingency plans. Beginning in March 2020 and continuing through this filing date, Customers Bancorp had a substantial number of its team members working remotely under such contingency plans. The execution of these contingency plans have not materially affected, or are reasonably likely to materially affect, Customers' internal control over financial reporting

Risks Related to the Disposition of BMT to MFAC

The amended agreement relating to BMT's proposed merger with MFAC provides for the issuance directly to our shareholders of the shares issuable by MFAC as part of the merger consideration. The future value of the shares you receive as a result of the merger and your ability to realize the value of your ownership of BM Technologies shares will be subject to a number of risks and challenges.

Our agreement with MFAC relating to the proposed merger of BMT and MFAC has recently been amended to provide that the shares issuable by MFAC in connection with the proposed merger will be issued directly to Customers Bancorp shareholders rather than being issued to and held by us. Ownership of shares of BM Technologies following completion of the merger will involve many of the risks we have previously described in our 2019 Form 10-K and subsequently filed quarterly reports on Form 10-Q for the periods ended March 31, 2020 and June 30, 2020 regarding the business, operations and prospects of our BankMobile business, as well as additional risks relating to the business, operations and prospects of BM Technologies as a stand-alone public company. As a result, the future value of the shares you receive will depend on BM Technologies’ future performance, as well as factors impacting the value of fintech companies generally, conditions in the financial markets and other factors affecting public companies including, but not limited to:

• BankMobile's limited history operating as a separate entity and lack of history operating independently of Customers Bank;

• the experience of BankMobile's management team managing BankMobile, and in managing a public company and the business and financing activities of an organization of BankMobile’s size;

• BankMobile's dependence on key individuals and its ability to identify, recruit and retain skilled sales, management, and technical personnel;

• BankMobile’s ability to continue to successfully implement its strategy, grow adoption and retention rates, and effectively manage future growth;

• BankMobile’s ability to maximize the expected benefits of its partnership with T-Mobile, and successfully maintain its relationship with T-Mobile and continue its white label agreement with respect to T-Mobile MONEY;

• the success of BankMobile's efforts to expand market reach and product portfolio beyond the limited number of products and markets that have been the primary source of its revenue, and its ability to do so in a timely manner;

• BankMobile's ability to address current and increasing competitive factors in the industries in which it will do business, including its ability to innovate or respond to evolving technological changes;.

• the potential negative effects if BankMobile is unable to maintain an effective system of disclosure controls and internal control over financial reporting;

• the effect of any changes in the availability of student loans or financial aid, as well as budget constraints, and changes in enrollment rates in traditional (on-campus) and non-traditional (online) institutions of higher education (including as a result of COVID), on demand for BankMobile's services;

• the effect of any changes in the current government financial aid regime that relies on the outsourcing of financial aid disbursements through higher education institutions;

86

Table of Contents

• the potential adverse effects on BankMobile’s business, financial condition, and results of operations of any termination of, or changes to, the MasterCard association registration;

• the potential adverse effects on BankMobile’s business, financial condition, and results of operations and/or its reputation of breaches of security measures, unauthorized access to or disclosure of data relating to clients, fraudulent activity, and infrastructure failures; and

• the potential adverse effects on BankMobile’s business, financial condition, and results of operations if it is unable to protect or enforce its intellectual property rights or if BankMobile becomes subject to claims that its services or solutions violate the patents or other intellectual property of others, which would be costly and time-consuming to defend.

Although our BankMobile division, as an operating segment of ours, recently became profitable, there can be no assurance that BMT, a component of our BankMobile division, will be profitable following completion of the merger or that BM Technologies will be able to successfully execute its business plan, address competitive conditions in its markets and take other actions necessary to increase its value.

The shares issuable by MFAC will be subject to a contractual restriction on the resale of those shares by Customers Bancorp shareholders for a period of twelve months after the closing of the merger, subject to certain exceptions. As a result, you may not be able to realize the value of shares you receive in the merger through a sale of part or all of those shares during that twelve-month period. In addition, the distribution of the MFAC shares to Customers Bancorp shareholders generally will be taxable to shareholders receiving those shares as a qualified dividend for federal, state and local income tax purposes and, under certain circumstances, also may be subject to "net investment income" tax.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

On November 26, 2013, the Bancorp's board of directors authorized a stock repurchase plan in which the Bancorp could acquire up to 5% of its current outstanding shares not to exceed a 20% premium over the then current book value. On December 11, 2018, the Bancorp's board of directors amended the terms of the 2013 stock repurchase plan to adjust the repurchase terms and book value measurement date such that Customers was authorized to purchase shares of common stock at prices not to exceed the book value per share of Customers' common stock measured as of September 30, 2018. Customers repurchased all remaining authorized shares pursuant to this program in January 2019. Accordingly, there were no common shares repurchased during third quarter 2020.

Dividends on Common Stock

Customers Bancorp historically has not paid any cash dividends on its shares of common stock and does not expect to do so in the foreseeable future.

Any future determination relating to our dividend policy will be made at the discretion of Customers Bancorp’s board of directors and will depend on a number of factors, including earnings and financial condition, liquidity and capital requirements, the general economic and regulatory climate, ability to service any equity or debt obligations senior to our common stock, including obligations to pay dividends to the holders of Customers Bancorp's issued and outstanding shares of preferred stock and other factors deemed relevant by the Board of Directors.

In addition, as a bank holding company, Customers Bancorp is subject to general regulatory restrictions on the payment of cash dividends. Federal bank regulatory agencies have the authority to prohibit bank holding companies from engaging in unsafe or unsound practices in conducting their business, which, depending on the financial condition and liquidity of the holding company at the time, could include the payment of dividends. Further, various federal and state statutory provisions limit the amount of dividends that bank subsidiaries can pay to their parent holding company without regulatory approval. Generally, subsidiaries are prohibited from paying dividends when doing so would cause them to fall below the regulatory minimum capital levels, and limits exist on paying dividends in excess of net income for specified periods.

Beginning January 1, 2015, the ability to pay dividends and the amounts that can be paid will be limited to the extent the Bank's capital ratios do not exceed the minimum required levels plus 250 basis points, as these requirements were phased in through January 1, 2019.

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 and nine months ended September 30, 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 the 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.

The following table illustrates the impact of adopting ASC 326:

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 installment. 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 indices). 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 a separate financial statement line item 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, 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 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 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.

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 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.

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 $4.2 million at September 30, 2020 and is excluded from the estimate of credit losses.

Accounting and Reporting Considerations related to COVID-19

On March 27, 2020, the CARES Act was signed into law and contained substantial tax and spending provisions intended to address the impact of the COVID-19 pandemic and stimulate the economy. The CARES Act includes the PPP designed to aid small-and medium-sized businesses through federally guaranteed loans distributed through banks. Customers is a participant in the PPP. Section 4013 of the CARES act also gives entities temporary relief from the accounting and disclosure requirements for TDRs under ASC 310-40 in certain situations.

Accounting for PPP Loans

In April 2020, Customers began to originate loans to qualified small businesses under the PPP administered by the SBA. The PPP loans are fully guaranteed by the SBA and may be eligible for forgiveness by the SBA to the extent that the proceeds are used for payroll and other permitted purposes in accordance with the requirements of the PPP. These loans carry a fixed rate of 1.00% and terms of two or five years, if not forgiven, in whole or in part. Payments are deferred for the first six months of the loan. The loans are 100% guaranteed by the SBA. The SBA pays the originating bank a processing fee ranging from 1% to 5% based on the size of the loan. Customers classified the PPP loans as held for investment and these loans are carried at amortized cost and interest income is recognized using the interest method. The origination fees, net of direct origination costs, are deferred and recognized as an adjustment to the yield of the related loans over their contractual life using the interest method. As PPP is newly created, Customers does not have historical prepayment data to accurately estimate principal prepayments and therefore has elected to not estimate prepayments as a policy election. No allowance for credit losses has been recognized for PPP loans as these loans are 100% guaranteed by the SBA. See Note 7 - Loans and Leases Receivable and Allowance for Credit Losses on Loans and Leases for additional information.

Loan Modifications

As mentioned above, Section 4013 of the CARES Act gives entities temporary relief from the accounting and disclosure requirements for TDRs. In addition, on April 7, 2020, certain regulatory banking agencies issued an interagency statement that offers practical expedients for evaluating whether loan modifications in response to the COVID-19 pandemic are TDRs. To qualify for TDR accounting and disclosure relief under the CARES Act, the applicable loan must not have been more than 30 days past due as of December 31, 2019, and the modification must be executed during the period beginning on March 1, 2020, and ending on the earlier of December 31, 2020, or the date that is 60 days after the termination date of the national emergency declared by the president on March 13, 2020, under the National Emergencies Act related to the outbreak of COVID-19. The CARES Act applies to modifications made as a result of COVID-19 including: forbearance agreements, interest rate modifications, repayment plans, and other arrangements to defer or delay payment of principal or interest. The interagency statement does not require the modification to be completed within a certain time period if it is related to COVID-19 and can be provided to borrowers either individually or as part of a loan modification program. Moreover, the interagency statement applies to short-term modifications (e.g. not more than six months deferral) including payment deferrals, fee waivers, extensions of repayment terms, or other insignificant payment delays as a result of COVID-19.

Customers applied Section 4013 of the CARES Act and the interagency statement in connection with applicable modifications. For modifications that qualify under either the CARES Act or the interagency statement, TDR accounting and reporting is suspended. These modifications generally involve principal and/or interest payment deferrals for a period of 90 days at a time and can be extended to six months or longer for modifications that qualified under the Section 4013 of the CARES Act if requested by the borrower as long as the reason is still related to COVID-19. These modified loans would not also be reported as past due or nonaccrual during the deferral period. See Note 7 - Loans and Leases Receivable and Allowance for Credit Losses on Loans and Leases for additional information.

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. These securities were sold for $15.4 million with a realized gain of $1.0 million during the three months ended September 30, 2020.

During the three and nine months ended September 30, 2020, Customers recognized unrealized gains of $0.2 million and $0.1 million, respectively, on its equity securities. During the three and nine months ended September 30, 2019, Customers recognized unrealized gains of $1.3 million and $1.0 million, 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.

Proceeds from the sale of available for sale debt securities were $268.6 million and $377.8 million for the three and nine months ended September 30, 2020. Realized gains from the sale of available for sale debt securities were $11.7 million and $20.0 million for the three and nine months ended September 30, 2020, respectively. Proceeds from the sale of available for sale debt securities were $97.6 million for the three and nine months ended September 30, 2019. Realized gains from the sale of available for sale debt securities were $1.0 million for the three and nine months ended September 30, 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 other assets 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:

At September 30, 2020, there were fifteen 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 were principally due to changes in market interest rates that resulted in a negative impact on the respective securities' fair value. All amounts related to these securities are expected to be recovered when market prices recover or at maturity. Customers does not intend to sell any of the 15 securities, and it is not more likely than not that Customers will be required to sell any of the 15 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 September 30, 2020 and December 31, 2019, Customers Bank had pledged investment securities aggregating $20.1 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 September 30, 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.

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 $61.9 million and $34.8 million at September 30, 2020

and December 31, 2019, respectively, and is presented in accrued interest receivable in the consolidated balance sheet. At September 30, 2020, there were $32.1 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.

Loans receivable, PPP:

On March 27, 2020, the CARES Act was signed into law and created funding for a new product called the PPP. The PPP is administered by the SBA and is intended to assist organizations with payroll related expenses. Customers had $5.0 billion of PPP loans outstanding as of September 30, 2020, which are fully guaranteed by the SBA and earn a fixed interest rate of 1.00%. Customers recognized interest income, including origination fees, of $24.3 million and $36.0 million for the three and nine months ended September 30, 2020, respectively.

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 September 30, 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.

(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. The September 30, 2020 table excludes PPP loans of $5.0 billion which are all current as of September 30, 2020.

(3)Includes purchased credit deteriorated loans of $14.4 million at September 30, 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 September 30, 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 September 30, 2020 and December 31, 2019, the Bank had initiated foreclosure proceedings on $0.5 million and $0.9 million, respectively, in loans secured by residential real estate.

At September 30, 2020, the ACL was $155.6 million, an increase of $19.4 million from the January 1, 2020 balance of $136.2 million. The increase resulted primarily from the impact of reserve build for the COVID-19 pandemic including the change in macroeconomic forecasts, an increase in net charge-offs, mostly attributed to the commercial real estate non-owner occupied and installment portfolios, and portfolio growth mainly in the installment portfolio. Commercial real estate non-owner occupied charge-offs are attributable to two collateral dependent loans. Installment charge-offs are attributable to delinquencies and defaults of originated and purchased unsecured consumer installment loans through arrangements with fintech companies and other market place lenders.

PPP loans include an embedded credit enhancement guarantee from the SBA, which guarantees 100% of all principal and interest owed by the borrower. Therefore, Customers did not include an ACL for PPP loans as of September 30, 2020.

Troubled Debt Restructurings

At September 30, 2020 and December 31, 2019, there were $16.1 million and $13.3 million, respectively, in loans reported as TDRs. TDRs are reported as impaired loans in the quarter of their restructuring and are evaluated to determine whether they should be placed on non-accrual status. In subsequent quarters, a TDR may be returned to accrual status if it satisfies a minimum performance requirement of six months, however, it will remain classified as impaired. Generally, the Bank requires sustained performance for nine months before returning a TDR to accrual status. Customers had no lease receivables that had been restructured as a TDR as of September 30, 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 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. At September 30, 2020, commercial and consumer deferments related to COVID-19 were $79.0 million and $25.0 million, respectively.

The following table presents loans modified in a TDR by type of concession for the three and nine months ended September 30, 2020 and 2019. There were no modifications that involved forgiveness of debt for the three and nine months ended September 30, 2020 and 2019.

As of September 30, 2020 and 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:

	September 30, 2020			September 30, 2019
(dollars in thousands)	Number of loans	Recorded investment		Number of loans	Recorded investment
Manufactured housing	5	$	201	3	$	76

Residential real estate	1	95		1	82
Installment	8	$	126	—	$	—
Total loans	15	$	1,374	4	$	158

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 September 30, 2020, the amortized cost basis of PCD assets amounted to $14.4 million.

Credit Quality Indicators

The ACL represents management's estimate of expected losses in Customers' loans and leases receivable portfolio, excluding commercial mortgage warehouse loans reported at fair value pursuant to a fair value option election and PPP loans receivable. Multi-family, commercial and industrial, owner occupied commercial real estate, non-owner occupied commercial real estate, and construction loans are rated based on an internally assigned risk rating system which is assigned at the time of loan origination and reviewed on a periodic, or on an “as needed” basis. Residential real estate loans, manufactured housing and installment loans are evaluated based on the payment activity of the loan.

To facilitate the monitoring of credit quality within the multi-family, commercial and industrial, owner occupied commercial real estate, non-owner occupied commercial real estate, and construction loan portfolios, and as an input in the ACL lifetime loss rate model for the 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 September 30, 2020 and December 31, 2019. PPP loans are excluded in the tables below as these loans are fully guaranteed by the SBA.

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.

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 Customers' Split-TRAC leases have 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.

Regulatory Capital [Abstract]

Regulatory Capital

REGULATORY CAPITAL

The Bank and the Bancorp are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet the minimum capital requirements can result in certain mandatory, and possibly additional discretionary, actions by regulators that, if undertaken, could have a direct material effect on Customers' financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Bank and the Bancorp must meet specific capital guidelines that involve quantitative measures of their assets, liabilities and certain off-balance sheet items, as calculated under the regulatory accounting practices. The capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors. Prompt corrective action provisions are not applicable to bank holding companies.

In first quarter 2020, U.S federal banking regulatory agencies permitted banking organizations to phase-in, for regulatory capital purposes, the day-one impact of the new CECL accounting rule on retained earnings over a period of three years. As part of its response to the impact of COVID-19, on March 31, 2020, the U.S. federal banking regulatory agencies issued an interim final rule that provided the option to temporarily delay certain effects of CECL on regulatory capital for two years, followed by a three-year transition period. The interim final rule allows banking organizations to delay for two years 100% of the day-one impact of adopting CECL and 25% of the cumulative change in the reported allowance for credit losses since adopting CECL. Customers has elected to adopt the interim final rule, which is reflected in the regulatory capital data presented below.

In April 2020, the U.S. federal banking regulatory agencies issued an interim final rule that permits banks to exclude the impact of participating in the SBA PPP program in their regulatory capital ratios. Specifically, PPP loans are zero percent risk weighted and a bank can exclude all PPP loans pledged as collateral to the PPPLF from its average total consolidated assets for purposes of calculating the Tier 1 capital to average assets ratio (i.e. leverage ratio). Customers applied this regulatory guidance in the calculation of its regulatory capital ratios presented below.

Quantitative measures established by regulation to ensure capital adequacy require the Bank and the Bancorp to maintain minimum amounts and ratios (set forth in the following table) of common equity Tier 1, Tier 1, and total capital to risk-weighted assets, and Tier 1 capital to average assets (as defined in the regulations). At September 30, 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:

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.

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 September 30, 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”. These assets are classified as Level 3 fair values, based upon the lowest level of input that is significant to the fair value measurements.

The estimated fair values of Customers' financial instruments at September 30, 2020 and December 31, 2019 were as follows.

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 $15.9 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 federal funds purchased) and a variable-rate deposit relationship over a maximum period of 67 months (excluding forecasted transactions related to the payment of variable interest on existing financial instruments).

At September 30, 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 September 30, 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 September 30, 2020, Customers had 154 interest rate swaps with an aggregate notional amount of $1.4 billion and six interest rate caps with an aggregated notional amount of $122.1 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 September 30, 2020 and December 31, 2019, Customers had an outstanding notional balance of residential mortgage loan commitments of $19.4 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 September 30, 2020 and December 31, 2019, Customers had outstanding notional balances of credit derivatives of $172.9 million and $167.1 million, respectively.

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 September 30, 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 $114.5 million. In addition, Customers, which has collateral posting thresholds with certain of these counterparties, had posted $110.0 million of cash as collateral at September 30, 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.

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 consumer installment 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 partners.

The following tables present the operating results for Customers' reportable business segments for the three and nine months ended September 30, 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 20.61% for 2020 and 23.15% for 2019, respectively.

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.

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 ED 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 ED 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 ED’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 ED’s Office of Hearing and Appeals.

On March 26, 2020, the ED 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 ED 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.

Business Combinations [Abstract]

Bankmobile Technologies, Inc. Merger

BANKMOBILE TECHNOLOGIES, INC. MERGER

On August 6, 2020, Customers Bank, BMT, a subsidiary of Customers Bank, and MFAC, a special purpose acquisition company, entered into a definitive merger agreement. BMT is the technology arm of Customers' BankMobile reporting segment. Upon closing of the transaction, the combined company will operate as BM Technologies and expects to be listed on the New York Stock Exchange. All BMT serviced deposits and loans will remain at the Bank immediately after the closing of the transaction. Upon the closing of the transaction, BM Technologies will be a financial technology company bringing banks and business partners together through its digital banking platform.

Merger Consideration

The aggregate consideration to be paid in connection with the merger will be an amount (the “Merger Consideration”) equal to: (i) $140.0 million minus (ii) $9.3 million (representing a sponsor equity adjustment), plus (or minus, if negative) (iii) BMT’s net working capital less a target net working capital of $10.0 million, minus (iv) the aggregate amount of any outstanding indebtedness of BMT at closing, and minus (v) the amount of any unpaid transaction expenses of BMT, MFAC’s transaction expenses and other liabilities of MFAC due and owing at the closing of the transaction.

The Merger Consideration will consist of cash and stock. The cash portion of the Merger Consideration (“Cash Consideration”) will be equal to (i) the amount of any proceeds of the PIPE Investment; plus (ii) an amount equal to one-half (1/2) of the difference between the (A) cash and cash equivalents of MFAC, including any funds in the trust account after giving effect to the completion of the redemption of shares of MFAC’s public stockholders (“Redemption”), less (B) a cash reserve to be used for the benefit of BM Technologies in the Merger, in the amount of $10.0 million (such difference between clause (A) and (B) which resulting amount if otherwise negative shall be equal to zero, being which resulting amount if otherwise negative shall be equal to zero, being the “Remaining Trust Account Amount”); minus (iii) MFAC’s transaction expenses and other liabilities of MFAC due and owing at the Business Combination Closing; plus (iv) the cash and cash equivalents of BMT; minus (v) BMT’s unpaid transaction expenses; minus (vi) a cash reserve in the amount of $5.0 million. The stock portion of the Merger Consideration consists of a number of shares of MFAC’s Class A common stock with an aggregate value (the “Merger Consideration Share Amount”) equal to (a) the Merger Consideration, minus (b) the Cash Consideration, with Customers Bancorp's stockholders receiving a number of shares of MFAC Class A common stock equal to the Merger Consideration Share Amount, divided by $10.38 (the “Per Share Price”).

The Merger Consideration is subject to adjustment after the closing date based on confirmed amounts of the net working capital of BMT, the outstanding indebtedness of BMT and any unpaid transaction expenses of BMT, as of the closing date. The adjustment amount shall be the Merger Consideration as finally determined minus the estimated Merger Consideration that was issued at the closing date of the transaction. If the adjustment is a negative adjustment in favor of MFAC, the Bank will pay MFAC the absolute value of the adjustment amount in cash. If the adjustment is a positive adjustment in favor of BMT, MFAC will issue to the Bank an additional number of shares of Class A Common Stock of MFAC with a value equal to the adjustment amount (with each share valued at the per share price). The Merger Consideration is also subject to reduction for the indemnification obligations of the Bank.

Certain Relationships

Mr. Jay Sidhu, who currently serves as Chief Executive Officer and Chairman of the Board of Customers Bancorp and Executive Chairman of the Bank, also serves as a director of MFAC, is one of the managing members of MFAC’s sponsor and is a MFAC stockholder and also served as Executive Chairman of MFAC through August 7, 2020. Mr. Bhanu Choudhrie, who currently serves as a member of the board of directors of Customers Bancorp and the Bank also serves as a director of MFAC, is one of the managing members of MFAC’s sponsor and is a MFAC stockholder. Mr. Samvir Sidhu, the son of Jay Sidhu, currently serves as the Bank’s Vice Chairman and Chief Operating Officer and as Customers Bancorp’s Head of Corporate Development, previously served as the Chief Executive Officer of MFAC, currently serves as a director of MFAC and is a MFAC stockholder. Ms. Luvleen Sidhu, the daughter of Jay Sidhu, currently serves as the Chief Executive Officer and as a director of BMT and is expected to continue to serve in those roles with BM Technologies. Certain of these individuals also expect to participate in the private placement by MFAC of shares of its Class A common stock to be completed in connection with the closing.

In light of these relationships, Customers Bancorp appointed a special committee consisting of independent directors with their own counsel and financial advisors. The special committee reviewed the transaction, obtained a fairness opinion in connection with the transaction, and made a unanimous recommendation to Customers Bancorp’s board of directors for approval. Customers Bancorp’s board of directors approved the transaction by a majority vote, with the above-mentioned directors recusing themselves from the deliberation and voting process and no director voting against the transaction.

Amendment to the Merger Agreement

On November 2, 2020, the Bank, BMT and MFAC amended the merger agreement to provide, among other things, that the stock portion of the Merger Consideration will be distributed to Customers Bancorp's stockholders at the closing of the transaction and that there will be restrictions on the sale of these shares for twelve months after the closing of the merger, provided that these restrictions will end prior to such time upon the earlier of (1) the date after the closing date on which MFAC consummates a liquidation, merger, capital stock exchange, reorganization or other similar transaction with an unaffiliated third-party that results in all of MFAC’s stockholders having the right to exchange their shares of common stock for cash, securities or other property, and (2) the date on which the closing sale price of MFAC’s common stock equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations and recapitalizations and the like) for any 20 trading days within any 30 trading day period commencing at least 150 days after the closing date.

The merger is expected to close in the fourth quarter 2020, pending MFAC stockholders' approval, regulatory approval and the satisfaction or waiver of additional conditions to closing. As of September 30, 2020, BMT had an outstanding borrowing with the Bank totalling $40 million. All or a portion of this borrowing is expected to remain outstanding after the merger transaction. As of September 30, 2020, Customers has determined that the planned divestiture of BMT through this merger transaction did not qualify for reporting as a discontinued operation. BMT, as a component of the BankMobile segment, did not meet the criteria to be classified as held for sale as the merger transaction is subject to MFAC shareholders' approval, regulatory approval, and other required conditions to closing as discussed above. Accordingly, Customers continues to report the operating results of BMT within the BankMobile segment. See NOTE 13 - BUSINESS SEGMENTS.

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 and nine months ended September 30, 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 the 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.

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 installment. 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 indices). 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 a separate financial statement line item 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, 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 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 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.

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 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.

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 $4.2 million at September 30, 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.

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.

(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. The September 30, 2020 table excludes PPP loans of $5.0 billion which are all current as of September 30, 2020.

(3)Includes purchased credit deteriorated loans of $14.4 million at September 30, 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.
