NOTE 2 — 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, 2022 consolidated balance sheet presented in this report has been derived from Customers Bancorp’s audited 2022 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 2022 consolidated financial statements of Customers Bancorp and subsidiaries included in Customers' Annual Report on Form 10-K for the year ended December 31, 2022 filed with the SEC on February 28, 2023 (the "2022 Form 10-K"). The 2022 Form 10-K describes Customers Bancorp’s significant accounting policies. There have been no material changes to Customers Bancorp's significant accounting policies noted above for the three months ended March 31, 2023.

Recently Issued Accounting Standards

These relate only to those contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. Certain optional expedients and exceptions in ASC 848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition, including derivative instruments that use an interest rate for margining, discounting, or contract price alignment that is modified as a result of reference rate reform. • Amends the definition of the SOFR Overnight Index Swap Rate to any rate based on SOFR qualifies as a benchmark interest rate for purposes of applying fair value hedge accounting. • Effective as of December 21, 2022 and ASC 848 can be adopted anytime during the period of January 1, 2020 through December 31, 2024.	• Customers adopted the guidance in ASC 848 during the adoption period for certain optional expedients. • The adoption of ASC 848 did not have a material impact on Customers' financial condition, results of operations and consolidated financial statements. • As of March 31, 2023, Customers has not yet elected to apply optional expedients for certain contract modifications. We plan to elect additional optional expedients in the future, which are not expected to have a material impact on Customers' financial condition, results of operations and consolidated financial statements.

Customers' transactions with unconsolidated VIEs include sales of consumer installment loans and investments in the securities issued by the VIEs. Customers is not the primary beneficiary of the VIEs because Customers has no right to make decisions that will most significantly affect the economic performance of the VIEs. Customers' continuing involvement with the unconsolidated VIEs is not significant. Customers' continuing involvement is not considered to be significant where Customers only invests in securities issued by the VIE and was not involved in the design of the VIE or where Customers has transferred financial assets to the VIE for only cash consideration. Customers' investments in the securities issued by the VIEs are classified as AFS or HTM debt securities on the consolidated balance sheets, and represent Customers' maximum exposure to loss.

There were no sales of AFS debt securities for the three months ended March 31, 2023. Proceeds from the sale of AFS debt securities were $156.0 million for the three months ended March 31, 2022.

At March 31, 2023, there were 50 AFS debt securities with unrealized losses in the less-than-twelve-months category and 112 AFS debt securities with unrealized losses in the twelve-months-or-more category. Except for the four asset-backed securities and six corporate notes where there was a deterioration in future estimated cash flows as further discussed below, the unrealized losses were principally due to changes in market interest rates that resulted in a negative impact on the respective securities' fair value and are expected to be recovered when market prices recover or at maturity. Customers does not intend to sell any of the 162 securities, and it is not more likely than not that Customers will be required to sell any of the 162 securities before recovery of the amortized cost basis. At December 31, 2022, there were 156 AFS debt securities in an unrealized loss position.

Customers recorded an allowance for credit losses on four asset-backed securities and six corporate notes where there was a deterioration in future estimated cash flows during the three months ended March 31, 2023 and on four asset-backed securities during the three months ended March 31, 2022. A discounted cash flow approach is used to determine the amount of the allowance. The cash flows expected to be collected, after considering expected prepayments, are discounted at the original effective interest rate. The amount of the allowance is limited to the difference between the amortized cost basis of the security and its estimated fair value.

The following table presents HTM debt securities by stated maturity. Debt securities backed by mortgages and other assets have expected maturities that differ from contractual maturities because borrowers have the right to call or prepay and, therefore, these debt securities are classified separately with no specific maturity date:

Customers recorded no allowance for credit losses on investment securities classified as held to maturity at March 31, 2023 and December 31, 2022. The U.S. government agency securities represent obligations issued by a U.S. government-sponsored enterprise or other federal government agency that are explicitly or implicitly guaranteed by the U.S. federal government and therefore, assumed to have zero credit losses. Most of the private label collateralized mortgage obligations are highly rated and with sufficient overcollateralization, therefore have zero expected credit losses. Customers recorded no allowance for its investment in the asset-backed securities. Customers considered the seniority of its beneficial interest, which includes its overcollateralization of these asset-backed securities in the estimate of the ACL at March 31, 2023 and December 31, 2022. The unrealized losses on HTM debt securities with no ACL were due to changes in market interest rates that resulted in a negative impact on the respective securities' fair value and are expected to be recovered when market prices recover or at maturity.

Credit Quality Indicators

Customers monitors the credit quality of HTM debt securities primarily through credit ratings provided by rating agencies. Investment grade debt securities are rated BBB- or higher by S&P Global Ratings, Baa3 or higher by Moody's Investors Service or equivalent ratings by other rating agencies, and are generally considered to be of low credit risk. Except for the asset-backed securities and a private label collateralized mortgage obligation, all of the HTM debt securities held by Customers were investment grade or U.S. government agency guaranteed securities that were not rated at March 31, 2023 and December 31, 2022. The asset-backed securities and a private label collateralized mortgage obligation are not rated by rating agencies. Customers monitors the credit quality of these asset-backed securities and a private label collateralized mortgage obligation by evaluating the performance of the sold consumer installment loans and other underlying loans against the overcollateralization available for these securities.

Customers' total loans and leases receivable 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, 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 $100.9 million and $105.5 million at March 31, 2023 and December 31, 2022, respectively, and is presented in accrued interest receivable in the consolidated balance sheet. At March 31, 2023 and December 31, 2022, there were $13.8 million and $11.5 million of individually evaluated loans that were collateral-dependent, respectively. Substantially all individually evaluated loans are collateral-dependent and consisted primarily of commercial and industrial, commercial real estate, and residential real estate loans. Collateral-dependent commercial and industrial loans were secured by accounts receivable, inventory and equipment; collateral-dependent commercial real estate loans were secured by commercial real estate assets; and residential real estate loans were secured by residential real estate assets.

Loans receivable, mortgage warehouse, at fair value

Mortgage warehouse loans consist of commercial loans to mortgage companies. These mortgage warehouse lending transactions are subject to master repurchase agreements. As a result of the contractual provisions, for accounting purposes, control of the underlying mortgage loan has not transferred and the rewards and risks of the mortgage loans are not assumed by Customers. The mortgage warehouse loans are designated as loans held for investment and reported at fair value based on an election made to account for the loans at fair value. Pursuant to the agreements, Customers funds the pipelines for these mortgage lenders by sending payments directly to the closing agents for funded mortgage loans and receives proceeds directly from third party investors when the underlying mortgage loans are sold into the secondary market. The fair value of the mortgage warehouse loans is estimated as the amount of cash initially advanced to fund the mortgage, plus accrued interest and fees, as specified in the respective agreements. The interest rates on these loans are variable, and the lending transactions are short-term, with an average life under 30 days from purchase to sale. The primary goal of these lending transactions is to provide liquidity to mortgage companies.

At March 31, 2023 and December 31, 2022, all of Customers' commercial mortgage warehouse loans were current in terms of payment. As these loans are reported at their fair value, they do not have an ACL and are therefore excluded from ACL-related disclosures.

Loans receivable, PPP

Customers had $246.3 million and $998.2 million of PPP loans outstanding as of March 31, 2023 and December 31, 2022, respectively, which are fully guaranteed by the SBA, provided that the SBA's eligibility criteria are met and earn a fixed interest rate of 1.00%. Customers recognized interest income, including net origination fees, of $23.6 million and $36.9 million for the three months ended March 31, 2023 and 2022, respectively.

PPP loans include an embedded credit enhancement from the SBA, which guarantees 100% of the principal and interest owed by the borrower provided that the SBA's eligibility criteria are met. As a result, the eligible PPP loans do not have an ACL and are therefore excluded from ACL-related disclosures.

At March 31, 2023, the ACL on loans and leases was $130.3 million, a decrease of $0.6 million from the December 31, 2022 balance of $130.9 million. The decrease in ACL for the three months ended March 31, 2023 was primarily attributable to a decrease in consumer installment loans, partially offset by additional provision for credit losses from the recognition of weaker macroeconomic forecasts.

Loan Modifications for Borrowers Experiencing Financial Difficulty

Customers adopted ASU 2022-02, Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures ("ASU 2022-02") effective January 1, 2023. The amendments in ASU 2022-02 eliminated the recognition and measurement of TDRs and enhanced the disclosures for loan modifications to borrowers experiencing financial difficulty. Refer to NOTE 2 – SIGNIFICANT ACCOUNTING POLICIES AND BASIS OF PRESENTATION for additional information on the adoption.

A borrower is considered to be experiencing financial difficulty when there is a significant doubt about the borrower's ability to make the required principal and interest payments on the loan or to get an equivalent financing from another creditor at a market rate for a similar loan.

When borrowers are experiencing financial difficulty, Customers may make certain loan modifications as part of loss mitigation strategies to maximize expected payment. To be classified as a modification made to a borrower experiencing financial difficulty the modification must be in the form of an interest rate reduction, principal forgiveness, or an other-than-insignificant payment delay (payment deferral), term extension, or combinations thereof.

Customers will generally try other forms of relief before principal forgiveness but would define any contractual reduction in the amount of principal due without receiving payment or assets as forgiveness. For the purpose of this disclosure, Customers considers any contractual change in interest rate that results in a reduction in interest rate relative to the current stated interest rate as an interest rate reduction. Generally, Customers would consider any delay in payment of greater than 90 days in the last 12 months to be significant. Term extensions extend the original contractual maturity of the loan. For the purpose of this disclosure, modification of contingent payment features or covenants that would have accelerated payment are not considered term extensions.

The performance of loans made to borrowers experiencing financial difficulty in which modifications were made is closely monitored to understand the effectiveness of modification efforts. Loans are considered to be in payment default at 90 days or more past due. The following table presents an aging analysis of loan modifications made to borrowers experiencing financial difficulty during the three months ended March 31, 2023.

As of March 31, 2023, Customers did not have any loans that were made to borrowers experiencing financial difficulty during the three months ended March 31, 2023 that subsequently defaulted. Customers' ACL is influenced by loan level characteristics that inform the assessed propensity to default. As such, the provision for credit losses is impacted by changes in such loan level characteristics, such as payment performance. Loans made to borrowers experiencing financial difficulty can be classified as either accrual or nonaccrual.

Troubled Debt Restructuring

At December 31, 2022, there were $16.8 million in loans reported as TDRs. The following table presents loans modified by type of concession for the three months ended March 31, 2022. There were no modifications that involved forgiveness of debt for the three months ended March 31, 2022.

	Three Months Ended March 31, 2022
(dollars in thousands)	Number of loans	Recorded investment
Interest-rate reductions	10	$	346
Other (1)	32	451
Total	42	$	797

(1) Other includes covenant modifications, forbearance, loans discharged under Chapter 7 bankruptcy, or other concessions.

As of December 31, 2022, there were no commitments to lend additional funds to debtors whose loans have been modified in TDRs.

The following table presents, by loan type, the number of loans modified in TDRs and the related recorded investment, for which there was a payment default within twelve months following the modification.

	March 31, 2022
(dollars in thousands)	Number of loans	Recorded investment
Manufactured housing	1	$	49
Installment	23	276
Total loans	24	$	325

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.

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. Commercial and industrial including specialty lending, multifamily, owner occupied commercial real estate, non-owner occupied commercial real estate, and construction loans are rated based on an internally assigned risk rating system which is assigned at the time of loan origination and reviewed on a periodic, or on an “as needed” basis. Residential real estate, manufactured housing and installment loans are evaluated based on the payment activity of the loan.

To facilitate the monitoring of credit quality within the commercial and industrial including specialty lending, multifamily, owner occupied commercial real estate, non-owner occupied commercial real estate, and construction loan portfolios, and as an input in the ACL lifetime loss rate model for the commercial and industrial loan portfolio, the Bank utilizes the following categories of risk ratings: pass/satisfactory (includes risk rating 1 through 6), special mention, substandard, doubtful, and loss. The risk rating categories, which are derived from standard regulatory rating definitions, are assigned upon initial approval of credit to borrowers and updated periodically thereafter. Pass ratings, which are assigned to those borrowers who do not have identified potential or well-defined weaknesses and for whom there is a high likelihood of orderly repayment, are updated periodically based on the size and credit characteristics of the borrower. All other categories are updated on a quarterly basis during the month preceding the end of the calendar quarter. While assigning risk ratings involves judgment, the risk-rating process allows management to identify riskier credits in a timely manner and allocate the appropriate resources to manage those loans and leases. The 2022 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 and current period gross write-offs as of March 31, 2023 and December 31, 2022.

NOTE 8 — LEASES

Lessee

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

As most of Customers' operating leases do not provide an implicit rate, Customers utilized its incremental borrowing rate when determining the present value of lease payments.

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.

NOTE 12 — 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, the U.S federal banking regulatory agencies permitted banking organizations to phase-in, for regulatory capital purposes, the day-one impact of the new CECL accounting rule on retained earnings over a period of three years. As part of its response to the impact of COVID-19, on March 31, 2020, the U.S. federal banking regulatory agencies issued an interim final rule that provided the option to temporarily delay certain effects of CECL on regulatory capital for two years, followed by a three-year transition period. The interim final rule allows banking organizations to delay for two years 100% of the day-one impact of adopting CECL and 25% of the cumulative change in the reported allowance for credit losses since adopting CECL. Customers has elected to adopt the interim final rule, which is reflected in the regulatory capital data presented below. The cumulative CECL capital transition impact as of December 31, 2021 which amounted to $61.6 million will be phased in at 25% per year beginning on January 1, 2022 through December 31, 2024. As of March 31, 2023, our regulatory capital ratios reflected 50%, or $30.8 million, benefit associated with the CECL transition provisions.

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

Quantitative measures established by regulation to ensure capital adequacy require the Bank and the Bancorp to maintain minimum amounts and ratios (set forth in the following table) of common equity Tier 1, Tier 1, and total capital to risk-weighted assets, and Tier 1 capital to average assets (as defined in the regulations). At March 31, 2023 and December 31, 2022, the Bank and the Bancorp satisfied all capital requirements to which they were subject.

The Basel III Capital Rules require that we maintain a 2.500% capital conservation buffer with respect to each of common equity Tier 1, Tier 1 and total capital to risk-weighted assets, which provides for capital levels that exceed the minimum risk-based capital adequacy requirements. 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 13 — DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS

Customers uses fair value measurements to record fair value adjustments to certain assets and liabilities and to disclose the fair value of its financial instruments. ASC 825, Financial Instruments, requires disclosure of the estimated fair value of an entity’s assets and liabilities considered to be financial instruments. For Customers, as for most financial institutions, the majority of its assets and liabilities are considered to be financial instruments. Many of these instruments lack an available trading market as characterized by a willing buyer and a willing seller engaging in an exchange transaction. For fair value disclosure purposes, Customers utilized certain fair value measurement criteria under ASC 820, Fair Value Measurements and Disclosures ("ASC 820"), as explained below.

36

Table of Contents

In accordance with ASC 820, the fair value of a financial instrument is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is best determined based upon quoted market prices. However, in many instances, there are no quoted market prices for Customers' various financial instruments. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. Accordingly, the fair value estimates may not be realized in an immediate settlement of the instrument.

The fair value guidance provides a consistent definition of fair value, focusing on an exit price in an orderly transaction (that is, not a forced liquidation or distressed sale) between market participants at the measurement date under current market conditions. If there has been a significant decrease in the volume and level of activity for the asset or liability, a change in valuation technique or the use of multiple valuation techniques may be appropriate. In such instances, determining the price at which willing market participants would transact at the measurement date under current market conditions depends on the facts and circumstances and requires the use of significant judgment. The fair value is a reasonable point within the range that is most representative of fair value under current market conditions.

The fair value guidance also establishes a fair value hierarchy and describes the following three levels used to classify fair value measurements.

Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.

Level 2: Quoted prices in markets that are not active, or inputs that are observable either directly or indirectly, for substantially the full term of the asset or liability.

Level 3: Prices or valuation techniques that require adjustments to inputs that are both significant to the fair value measurement and unobservable (i.e., supported with little or no market activity).

A financial instrument’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement.

The following methods and assumptions were used to estimate the fair values of Customers' financial instruments as of March 31, 2023 and December 31, 2022:

Financial Instruments Recorded at Fair Value on a Recurring Basis

Investment securities:

The fair values of equity securities with a readily determinable fair value, AFS debt securities and debt securities reported at fair value based on a fair value option election are determined by obtaining quoted market prices on nationally recognized and foreign securities exchanges (Level 1), quoted prices in markets that are not active (Level 2), matrix pricing (Level 2), which is a mathematical technique used widely in the industry to value debt securities without relying exclusively on quoted market prices for the specific securities but rather by relying on the securities’ relationship to other benchmark quoted prices, or internally and externally developed models that use unobservable inputs due to limited or no market activity of the instrument (Level 3).

When quoted market prices are not available, Customers employs an independent pricing service that utilizes matrix pricing to calculate fair value. Such fair value measurements consider observable data such as dealer quotes, market spreads, cash flows, yield curves, live trading levels, trade execution data, market consensus prepayments speeds, credit information, and respective terms and conditions for debt instruments. Management maintains procedures to monitor the pricing service's results and has an established process to challenge their valuations, or methodologies, that appear unusual or unexpected.

Customers also utilizes internally and externally developed models that use unobservable inputs due to limited or no market activity of the instrument. These models use unobservable inputs that are inherently judgmental and reflect our best estimates of the assumptions a market participant would use to calculate fair value. Certain unobservable inputs in isolation may have either a directionally consistent or opposite impact on the fair value of the instrument for a given change in that input. When multiple inputs are used within the valuation techniques, a change in one input in a certain direction may be offset by an opposite change from another input. These assets are classified as Level 1, 2 or 3 fair values, based upon the lowest level of input that is significant to the fair value measurements.

37

Table of Contents

Loans held for sale - Residential mortgage loans (fair value option):

Customers generally estimates the fair values of residential mortgage loans held for sale based on commitments on hand from investors within the secondary market for loans with similar characteristics. These assets are classified as Level 2 fair values, based upon the lowest level of input that is significant to the fair value measurements.

Loans receivable - Commercial mortgage warehouse loans (fair value option):

The fair value of commercial mortgage warehouse loans is the amount of cash initially advanced to fund the mortgage, plus accrued interest and fees, as specified in the respective agreements. The loan is used by mortgage companies as short-term bridge financing between the funding of the mortgage loans and the finalization of the sale of the loans to an investor. Changes in fair value are not generally expected to be recognized because at inception of the transaction the underlying mortgage loans have already been sold to an approved investor. Additionally, the interest rate is variable, and the transaction is short-term, with an average life of under 30 days from purchase to sale. These assets are classified as Level 2 fair values, based upon the lowest level of input that is significant to the fair value measurements.

Derivatives (assets and liabilities):

The fair values of interest rate swaps, interest rate caps and credit derivatives are determined using models that incorporate readily observable market data into a market standard methodology. This methodology nets the discounted future cash receipts and the discounted expected cash payments. The discounted variable cash receipts and payments are based on expectations of future interest rates derived from observable market interest rate curves. In addition, fair value is adjusted for the effect of nonperformance risk by incorporating credit valuation adjustments for Customers and its counterparties. These assets and liabilities are classified as Level 2 fair values, based upon the lowest level of input that is significant to the fair value measurements.

The fair values of the residential mortgage loan commitments are derived from the estimated fair values that can be generated when the underlying mortgage loan is sold in the secondary market. Customers generally uses commitments on hand from third party investors to estimate an exit price and adjusts for the probability of the commitment being exercised based on Customers' internal experience (i.e., pull-through rate). These assets and liabilities are classified as Level 3 fair values, based upon the lowest level of input that is significant to the fair value measurements.

Derivative assets and liabilities are presented in other assets and accrued interest payable and other liabilities on the consolidated balance sheet.

Financial Instruments Recorded at Fair Value on a Nonrecurring Basis

Collateral-dependent loans:

Collateral-dependent loans are those loans that are accounted for under ASC 326, Financial Instruments - Credit Losses ("ASC 326"), in which the Bank has measured impairment generally based on the fair value of the loan’s collateral or DCF analysis. Fair value is generally determined based upon independent third-party appraisals of the properties that collateralize the loans, DCF based upon the expected proceeds, sales agreements or letters of intent with third parties. These assets are generally classified as Level 3 fair values, based upon the lowest level of input that is significant to the fair value measurements.

The following information should not be interpreted as an estimate of Customers' fair value in its entirety because fair value calculations are only provided for a limited portion of Customers' assets and liabilities. Due to a wide range of valuation techniques and the degree of subjectivity used in making these estimates, comparisons between Customers' disclosures and those of other companies may not be meaningful.

NOTE 14 — DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

Risk Management Objectives of Using Derivatives

Customers is exposed to certain risks arising from both its business operations and economic conditions. Customers manages economic risks, including interest rate, liquidity and credit risk, primarily by managing the amount, sources, and durations of its assets and liabilities. Specifically, Customers enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the values of which are determined by interest rates. Customers’ derivative financial instruments are used to manage differences in the amount, timing, and duration of Customers’ known or expected cash receipts and its known or expected cash payments principally related to certain borrowings and deposits. Customers also has interest-rate derivatives resulting from an accommodation provided to certain qualifying customers, and therefore, they are not used to manage Customers’ interest-rate risk in assets or liabilities. Customers manages a matched book with respect to its derivative instruments used in this customer service in order to minimize its net risk exposure resulting from such transactions.

Fair Value Hedges of Benchmark Interest-Rate Risk

Customers is exposed to changes in the fair value of certain of its fixed rate AFS debt securities, deposits and FHLB advances due to changes in the benchmark interest rate. Customers uses interest rate swaps to manage its exposure to changes in fair value on these instruments attributable to changes in the designated benchmark interest rate such as the Fed Funds Effective Swap Rate. Interest rate swaps designated as fair value hedges of certain of its fixed rate AFS debt securities involve the payment of fixed-rate amounts to a counterparty in exchange for Customers receiving variable-rate payments over the life of the agreements without the exchange of the underlying notional amount. Interest rate swaps designated as fair value hedges of certain deposits and FHLB advances involve the payment of variable-rate amounts to a counterparty in exchange for Customers receiving fixed-rate payments over the life of the agreements without the exchange of the underlying notional amount. For derivatives designated and that qualify as fair value hedges, the gain or loss on the derivative as well as the offsetting loss or gain on the hedged item attributable to the hedged risk are recognized in net interest income.

Table of Contents

At March 31, 2023, Customers had three outstanding interest rate derivatives with notional amounts totaling $22.5 million that were designated as fair value hedges of certain AFS debt securities. During the three months ended March 31, 2023, Customers entered into, and terminated two interest rate derivatives with notional amounts totaling $550.0 million that were designated as fair value hedges of certain deposits and FHLB advances resulting in $4.6 million of basis adjustments which will be amortized over the remaining terms of the hedged items as a reduction in interest expense. During the three months ended March 31, 2022, Customers terminated two interest rate derivatives with notional amounts totaling $16.5 million that were designated as fair value hedges together with the sale of hedged AFS debt securities. At December 31, 2022, Customers had three outstanding interest rate derivatives with notional amounts totaling $22.5 million designated as fair value hedges of certain AFS debt securities.

As of March 31, 2023 and December 31, 2022, the following amounts were recorded on the consolidated balance sheet related to cumulative basis adjustments for fair value hedges.

Derivatives Not Designated as Hedging Instruments

Customers executes interest rate swaps (typically the loan customers will swap a floating-rate loan for a fixed-rate loan) and interest rate caps with commercial banking customers to facilitate their respective risk management strategies. The customer interest rate swaps and interest rate caps are simultaneously offset by interest rate swaps and interest rate caps that Customers executes with a third party in order to minimize interest-rate risk exposure resulting from such transactions. As the interest rate swaps and interest rate caps associated with this program do not meet the hedge accounting requirements, changes in the fair value of both the customer swaps and caps and the offsetting third-party market swaps and caps are recognized directly in earnings. At March 31, 2023, Customers had 139 interest rate swaps with an aggregate notional amount of $1.3 billion and 12 interest rate caps with an aggregated notional amount of $244.6 million related to this program. At December 31, 2022, Customers had 141 interest rate swaps with an aggregate notional amount of $1.3 billion and 12 interest rate caps with an aggregate notional amount of $245.8 million related to this program.

Customers enters into residential mortgage loan commitments in connection with its consumer mortgage banking activities to fund mortgage loans at specified rates and times in the future. These commitments are short-term in nature and generally expire in 30 to 60 days. The residential mortgage loan commitments that relate to the origination of mortgage loans that will be held for sale are considered derivative instruments under applicable accounting guidance and are reported at fair value, with changes in fair value recorded directly in earnings. At March 31, 2023 and December 31, 2022, Customers had an aggregate notional amount of residential mortgage loan commitments of $3.3 million and $1.5 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 recorded directly in earnings. At March 31, 2023 and December 31, 2022, Customers had an aggregate notional amount of credit derivatives of $123.5 million and $142.0 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 or with central clearing parties.

Agreements with major derivative dealer counterparties contain provisions whereby default on any of Customers' indebtedness would be considered a default on its derivative obligations. Customers also has entered into agreements that contain provisions under which the counterparty could require Customers to settle its obligations if Customers fails to maintain its status as a well/adequately capitalized institution. As of March 31, 2023, the fair value of derivatives in a net asset position (which includes accrued interest but excludes any adjustment for nonperformance-risk) related to these agreements was $21.0 million. In addition, Customers, which has collateral posting thresholds with certain of these counterparties, had received $23.0 million of cash as collateral at March 31, 2023. Customers records cash posted or received as collateral with these counterparties, except with a central clearing entity, as a reduction or an increase in the outstanding balance of cash and cash equivalents and an increase in the balance of other assets or other liabilities.

Disclosures about Offsetting Assets and Liabilities

The following tables present derivative instruments that are subject to enforceable master netting arrangements. Customers' interest rate swaps and interest rate caps with institutional counterparties are subject to master netting arrangements and are included in the tables below. Interest rate swaps and interest rate caps with commercial banking customers and residential mortgage loan commitments are not subject to master netting arrangements and are excluded from the tables below. Customers has not made a policy election to offset its derivative positions.

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.

(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 months ended March 31, 2023. 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' 2022 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.

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 leases 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 consolidated financial statements.

Impact of Macroeconomic and Banking Industry Uncertainties, COVID-19 and Geopolitical Conflict

The U.S. economy has strengthened since the spread of COVID-19 variants, with higher inflation and housing values beginning in 2021. Also, the ongoing global supply chain issues and the military conflict between Russia and Ukraine contributed to higher inflation in 2022. In response, the Federal Reserve began normalizing monetary policy with its decision in late 2021 to taper its quantitative easing and raising the federal funds rate beginning in March 2022. Inflation remains elevated in 2023, reflecting supply and demand imbalances related to COVID-19 and its variants, higher food and energy prices from the military conflict between Russia and Ukraine, and broader price pressures. The Federal Reserve has raised interest rates significantly throughout 2022 and in the early part of 2023 in attempts to bring the inflation to its long run target rate of two percent. Future rate hikes may occur during the remainder of 2023, as the Federal Reserve has indicated attaining a stance of monetary policy that is sufficiently restrictive to return inflation to two percent over time.

In early March 2023, regional banks, Silicon Valley Bank and Signature Bank were placed in receivership by the state regulators and the FDIC. Citing systemic risk to the U.S. banking system, the FDIC, Federal Reserve and the U.S. Department of Treasury announced that all depositors of Silicon Valley Bank and Signature Bank would be made whole and have access to their funds. The Federal Reserve has also established a new Bank Term Funding Program, which offers loans of up to one year in length to banks, savings associations, credit unions, and other eligible depository institutions pledging U.S. Treasuries, agency debt and mortgage-backed securities and other qualifying assets as collateral. These assets will be valued at par. The BTFP is an additional source of liquidity against high-quality securities, eliminating an institution's need to quickly sell those securities in times of stress. As of March 31, 2023, Customers had no advances outstanding under the Federal Reserve's discount window or the BTFP. Refer to "NOTE 10 – BORROWINGS" to Customers' unaudited consolidated financial statements.

Significant uncertainties as to future economic conditions continue to exist, including higher inflation and interest rate environment, elevated liquidity risk to the U.S. banking system, particularly to the regional banks, disruptions to global supply chain and labor markets and higher oil and commodity prices exacerbated by the military conflict between Russia and Ukraine. Customers has taken deliberate actions in response, including maintaining higher levels of liquidity, reserves for credit losses on loans and leases and off-balance sheet credit exposures and strong capital ratios. Customers has shifted the mix of its loan portfolio towards low credit risk commercial loans with floating or adjustable interest rates to position the Bank for higher interest rate hikes. Customers has also shifted the mix of its available for sale debt securities portfolio towards variable rate, shorter duration debt securities. The Bank's debt securities available for sale and held to maturity are available to be pledged as collateral to the FRB and FHLB for additional liquidity, including through the BTFP. The Bank had $7.4 billion in immediate available liquidity from FRB and FHLB and cash on hand of $2.0 billion as of March 31, 2023. The Bank also maintains a diversified deposit base with approximately 78% of our deposits (inclusive of accrued interest) insured by the FDIC, along with $393.9 million of state and municipal deposits collateralized by our lines of credit at FHLB and $54.9 million of deposits from our affiliates as of March 31, 2023. The Bank's FDIC insured, collateralized and affiliates' deposits represented approximately 81% of our deposits (inclusive of accrued interest) as of March 31, 2023. Customers is focused on growing its non-interest bearing and lower-cost interest-bearing deposits. Customers continues to monitor closely the impact of uncertainties affecting the macroeconomic conditions, the U.S. banking system, particularly regional banks, COVID-19 and its variants, the military conflict between Russia and Ukraine, as well as any effects that may result from the federal government's responses including future rate hikes and regulatory actions; however, the extent to which inflation, interest rates and other macroeconomic and industry factors, COVID-19 and its variants, the geopolitical conflict and developments in the U.S. banking system will impact Customers' operations and financial results during the remainder of 2023 is highly uncertain.

New Accounting Pronouncements

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

Critical Accounting Policies and Estimates

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 consolidated financial statements included in its 2022 Form 10-K and updated in this Form 10-Q for the quarterly period ended March 31, 2023 in "NOTE 2 – SIGNIFICANT ACCOUNTING POLICIES AND BASIS OF PRESENTATION" in Customers' unaudited consolidated financial statements.

47

Table of Contents

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 judgments 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 March 31, 2023 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 industry and state.

The ACL may be affected materially by a variety of qualitative factors that Customers considers to reflect its current judgment of various events and risks that are not measured in our statistical procedures, including uncertainty related to the economic forecasts used in the modelled 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, as deemed applicable, to arrive at a scenario or a composite of scenarios 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 a 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 President, Chief Financial Officer, Chief Accounting Officer, Chief Lending 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 judgments and the related disclosures are reviewed by Customers' Audit Committee of the Board of Directors.

The net decrease in our estimated ACL as of March 31, 2023 as compared to our December 31, 2022 estimate was primarily attributable to a decrease in consumer installment loans, partially offset by additional provision for credit losses from the recognition of weaker macroeconomic forecasts. There was a provision for credit losses on loans and leases of $18.0 million for the three months ended March 31, 2023, resulting in an ACL ending balance of $133.6 million ($130.3 million for loans and leases and $3.3 million for unfunded lending-related commitments) as of March 31, 2023.

To determine the ACL as of March 31, 2023, Customers utilized Moody's March 2023 Baseline forecast to generate its modelled expected losses and considered Moody's other alternative economic forecast scenarios to qualitatively adjust the modelled ACL by loan portfolio in order to reflect management's reasonable expectations of current and future economic conditions. The Baseline forecast at March 2023 assumed lower growth rate in macroeconomic forecasts compared to the fourth quarter 2022 forecasts of macroeconomic conditions used by Customers; the Federal Reserve Board delaying the increase in the effective fed funds rate due to the recent financial system turmoil, but ultimately raising it to the terminal range of 5.0% to 5.25%; policymakers' aggressive response ensures that the recent bank failures do not weaken the financial system or the U.S. economy; the CPI rising 4.1% in 2023 and 2.4% in 2024; and the unemployment rate rising at the end of 2023 and into 2024. Customers continues to monitor the impact of the U.S. banking system turmoil, military conflict between Russia and Ukraine, global supply chain and labor market disruptions, inflation, and related policy measures on the U.S. economy and, if pace of the expected recovery is worse than expected, further meaningful provisions for credit losses could be required.

As of December 31, 2022, the ACL ending balance was $133.9 million ($130.9 million for loans and leases and $3.0 million for unfunded lending-related commitments). To determine the ACL as of December 31, 2022, Customers utilized the Moody's December 2022 Baseline forecast to generate its modelled expected losses and considered Moody's other alternative economic forecast scenarios to qualitatively adjust the modelled ACL by loan portfolio in order to reflect management's reasonable expectations of current and future economic conditions. The Baseline forecast at December 31, 2022 assumed lower growth rates in macroeconomic forecasts compared to the macroeconomic forecasts used by Customers in 2021; oil prices remaining volatile, but gradually declining by mid-2023, from recession fears, weakening global economies and the embargo on Russian crude oil from the Russian invasion of Ukraine; COVID-19 becoming less disruptive to global supply chains, tourism and business travel, immigration and labor markets; the Federal Reserve raising the effective fed funds rate to just under 5.0% and cutting the fed funds rate beginning in late 2023 and throughout 2024; the CPI rising 4.1% in 2023 and 2.4% in 2024; and the unemployment rate rising to 4.0% in 2023 and 4.1% in 2024.

One of the most significant judgments influencing the ACL is the macroeconomic forecasts from Moody's. Changes in the economic forecasts could significantly affect the estimated credit losses which could potentially lead to materially different allowance levels from one reporting period to the next. Given the dynamic relationship between macroeconomic variables within Customers' modelling framework, it is difficult to estimate the impact of a change in any one individual variable on the ACL. However, to illustrate a hypothetical sensitivity analysis, management calculated a quantitative allowance using a 100% weighting applied to an adverse scenario. This scenario includes assumptions around the recent bank failures raising fears of further collapse in the banking industry, reducing consumer confidence and causing banks to tighten lending standards, the Federal Reserve keeping the fed funds rate elevated, but less than in the Baseline projections because of the weakening economy, military conflict between Russia and Ukraine persisting longer than expected, worsening supply chain conditions, rising unemployment and the U.S. economy falling into recession in the second quarter of 2023. Under this scenario, as an example, the unemployment rate is estimated at 5.6% and 7.6% in 2023 and 2024, respectively. These numbers represent a 2.1% and 3.7% higher unemployment estimate than the Baseline scenario projection of 3.5% and 3.9% for the same time periods, respectively. To demonstrate the sensitivity to key economic parameters, management calculated the difference between a 100% Baseline weighting and a 100% adverse scenario weighting for modelled results. This would result in an incremental quantitative impact to the ACL of approximately $38 million at March 31, 2023. This resulting difference is not intended to represent an expected increase in ACL levels since (i) Customers may use a weighted approach applied to multiple economic scenarios for its ACL process, (ii) the highly uncertain economic environment, (iii) the difficulty in predicting inter-relationships between macroeconomic variables used in various economic scenarios, and (iv) the sensitivity analysis does not account for any qualitative adjustments incorporated by Customers as part of its overall ACL framework.

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 geopolitical instability, risks of rising inflation including a near-term recession, worsening of the U.S. banking system turmoil, or the emergence of a more contagious and severe COVID-19 variant, 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 geopolitical instability, risks of rising inflation, worsening of the U.S. banking system turmoil, and COVID-19 and its variants have 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 $50.3 million for the three months ended March 31, 2023, compared to net income available to common shareholders of $74.9 million for the three months ended March 31, 2022. Factors contributing to the change in net income available to common shareholders for the three months ended March 31, 2023 compared to the three months ended March 31, 2022 were as follows.

Net interest income

Net interest income decreased $14.8 million for the three months ended March 31, 2023 compared to the three months ended March 31, 2022 due to higher funding costs from a shift in the mix of interest-bearing liabilities in a rising interest rate environment and reduced recognition of net deferred loan origination fees from PPP loans driven by lower loan forgiveness, which accelerated the recognition of net deferred loan origination fees, offset in part by an increase in commercial and industrial loans and leases, mostly due to higher interest rates on variable rate loans in specialty lending. Average interest-earning assets increased by $1.9 billion for the three months ended March 31, 2023, compared to the three months ended March 31, 2022. The increase in interest-earning assets was driven by increases in commercial and industrial loans and leases, primarily in specialty lending and multifamily loans, offset in part by decreases in PPP loans due to PPP loan forgiveness and guarantee payments from the SBA and commercial loans to mortgage companies. NIM decreased by 64 basis points to 2.96% for the three months ended March 31, 2023 from 3.60% for the three months ended March 31, 2022. The shift in the mix of interest-bearing liabilities in a rising interest rate environment drove a 331 basis point increase in the cost of interest-bearing liabilities and contributed to the NIM decrease for the three months ended March 31, 2023 compared to the three months ended March 31, 2022. The NIM decrease was partially offset by a shift in the mix of interest-earning assets in a rising interest rate environment mostly in commercial and industrial loans and leases, primarily in specialty lending, which drove a 221 basis point increase in the yield on interest-earning assets. The largest shift in the mix of interest-earning assets and interest-bearing liabilities impacting the NIM was $5.5 billion in ending balance ($5.7 billion average balance) of commercial and industrial loans and leases in specialty lending yielding 7.38% and $5.5 billion in ending balance ($4.5 billion average balance) of certificates of deposit costing 4.18% at and for the three months ended March 31, 2023. Customers' total cost of funds, including non-interest bearing deposits was 3.45% and 0.43% for the three months ended March 31, 2023 and 2022, respectively.

Provision for credit losses

The $3.6 million increase in the provision for credit losses for the three months ended March 31, 2023 compared to the three months ended March 31, 2022, primarily reflects the recognition of weaker macroeconomic forecasts. The ACL 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 statement of income. The ACL on loans and leases held for investment represented 0.99% of total loans and leases receivable, excluding PPP loans (non-GAAP measure, please refer to the non-GAAP reconciliation within Loans and Leases - Credit Risk), at March 31, 2023, compared to 1.44% at March 31, 2022. Net charge-offs for the three months ended March 31, 2023 were $18.7 million, or 49 basis points of average loans and leases on an annualized basis, compared to net charge-offs of $7.2 million, or 21 basis points on an annualized basis, for the three months ended March 31, 2022. The increase in net charge-offs for the three months ended March 31, 2023, compared to the three months ended March 31, 2022, was primarily due to higher charge-offs for consumer installment loans.

Table of Contents

The provision for credit losses for the three months ended March 31, 2023 and 2022 also included a provision for credit losses of $1.6 million and $0.7 million, respectively, on certain asset-backed securities and corporate notes included in our investment securities available for sale. Refer to "NOTE 5 – INVESTMENT SECURITIES" to Customers' unaudited consolidated financial statements for additional information.

Non-interest income

The $3.1 million decrease in non-interest income for the three months ended March 31, 2023 compared to the three months ended March 31, 2022 primarily resulted from decreases of $5.7 million in bank-owned life insurance income, $1.5 million in gain on sale of SBA and other loans, $0.9 million in mortgage warehouse transactional fees and $0.9 million in other non-interest income. These decreases were offset in part by increases of $3.4 million in commercial lease income and $1.4 million in loan fees and a decrease of $1.1 million in net loss on sale of investment securities for the three months ended March 31, 2023 compared to the three months ended March 31, 2022.

Non-interest expense

The $6.3 million increase in non-interest expense for the three months ended March 31, 2023 compared to the three months ended March 31, 2022 primarily resulted from increases of $5.7 million in salaries and employee benefits, $2.9 million in commercial lease depreciation, $2.3 million in loan servicing, $1.4 million in other non-interest expense, $0.7 million in advertising and promotion and $0.6 million in professional services. These increases were offset in part by a decrease of $7.5 million in technology, communication and bank operations for the three months ended March 31, 2023 compared to the three months ended March 31, 2022.

Income tax expense

Customers' effective tax rate was 21.3% for the three months ended March 31, 2023 compared to 20.1% for the three months ended March 31, 2022. The increase in the effective tax rate primarily resulted from lower death benefits from bank-owned life insurance policies and stock-based compensation benefits, partially offset by an increase in income tax credits.

Preferred stock dividends

Preferred stock dividends were $3.5 million and $1.9 million for the three months ended March 31, 2023 and 2022, respectively. There were no changes to the amount of preferred stock outstanding during the three months ended March 31, 2023 and 2022.

On June 15, 2021, the Series E Preferred Stock became floating at three-month LIBOR plus 5.14%, compared to a fixed rate of 6.45%. On December 15, 2021, the Series F Preferred Stock became floating at three-month LIBOR plus 4.762%, compared to a fixed rate of 6.00%. Pursuant to the Adjustable Interest Rate (LIBOR) Act enacted by Congress on March 15, 2022, Customers expects that the Series E and F Preferred Stock will substitute three-month term SOFR plus a tenor spread adjustment of 26.161 basis points for three-month LIBOR as the benchmark reference rate in order to calculate dividends after June 30, 2023.

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 table summarizes 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 months ended March 31, 2023 and 2022. 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.

(6)Not Meaningful. Average yield on other interest-earning assets for the three months ended March 31, 2022 was 44.18% primarily due to $5.2 million of equity investment distributions.

Net interest income decreased $14.8 million for the three months ended March 31, 2023 compared to the three months ended March 31, 2022 due to higher funding costs from a shift in the mix of interest-bearing liabilities in a rising interest rate environment and reduced recognition of net deferred loan origination fees from PPP loans driven by lower loan forgiveness, which accelerated the recognition of net deferred loan origination fees, offset in part by an increase in commercial and industrial loans and leases, mostly due to higher interest rates on variable rate loans in specialty lending. Average interest-earning assets increased by $1.9 billion, primarily related to increases in commercial and industrial loans and leases, primarily in specialty lending and multifamily loans, offset in part by decreases in PPP loans due to PPP loan forgiveness and guarantee payments from the SBA and commercial loans to mortgage companies. The commercial loans to mortgage companies trend had been a function of refinance activity, which had slowed since reaching its high level in early 2021, and into 2022 and 2023 with rising interest rates.

The NIM decreased by 64 basis points to 2.96% for the three months ended March 31, 2023 from 3.60% for the three months ended March 31, 2022 resulting primarily from a shift in the mix of interest-bearing liabilities in a rising interest rate environment, offset in part by a shift in the mix of interest-earning assets in a rising interest rate environment. The shift in the mix of interest-bearing liabilities in a rising interest rate environment drove a 331 basis point increase in the cost of interest-bearing liabilities and contributed to the NIM decrease for the three months ended March 31, 2023 compared to the three months ended March 31, 2022. The decrease in NIM was also due to reduced recognition of net deferred loan origination fees from PPP loans driven by lower loan forgiveness during the three months ended March 31, 2023 compared to the three months ended March 31, 2022. The decrease in NIM was offset in part by a shift in the mix of interest-earning assets in a rising interest rate environment, mostly in commercial and industrial loans and leases, primarily in specialty lending, which drove a 221 basis point increase in the yield on interest-earning assets. The largest shift in the mix of interest-earning assets and interest-bearing liabilities impacting the NIM was $5.5 billion in ending balance ($5.7 billion average balance) of commercial and industrial loans and leases within specialty lending yielding 7.38% and $5.5 billion in ending balance ($4.5 billion average balance) of certificates of deposit costing 4.18% at and for the three months ended March 31, 2023. Customers' total cost of funds, including non-interest bearing deposits was 3.45% and 0.43% for the three months ended March 31, 2023 and 2022, respectively.

Customers' net interest margin tables contain non-GAAP financial measures calculated using non-GAAP amounts. These measures include net interest margin tax equivalent, excluding PPP loans. Management uses these non-GAAP measures to compare 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 ACL at a level consistent with management’s assessment of expected lifetime losses in the loan and lease portfolio at the balance sheet date. Customers recorded a provision for credit losses on loans and leases during the three months ended March 31, 2023, which resulted primarily from the recognition of weaker macroeconomic forecasts. Customers recorded a provision for credit losses of $18.0 million for loans and leases and $0.3 million for lending-related commitments, respectively, for the three months ended March 31, 2023. Customers recorded a provision for credit losses for loans and leases of $15.3 million and a credit to provision for credit losses (a benefit) on lending-related commitments of $0.1 million, respectively, for the three months ended March 31, 2022. Net charge-offs for the three months ended March 31, 2023 were $18.7 million, or 49 basis points of average loans and leases on an annualized basis, compared to net charge-offs of $7.2 million, or 21 basis points of average loans and leases on an annualized basis, for the three months ended March 31, 2022. The increase in net charge-offs for the three months ended March 31, 2023, compared to the three months ended March 31, 2022, was primarily due to higher charge-offs for consumer installment loans.

Mortgage warehouse transactional fees

The $0.9 million decrease in mortgage warehouse transactional fees for the three months ended March 31, 2023 compared to the three months ended March 31, 2022 primarily resulted from lower refinancing activity due to higher interest rates. There can be no assurance that Customers will earn mortgage warehouse transactional fees in 2023 comparable to prior periods, given the lower mortgage banking activity in a higher interest rate environment.

Gain (loss) on sale of SBA and other loans

The $1.5 million decrease in gain on sale of SBA and other loans for the three months ended March 31, 2023 compared to the three months ended March 31, 2022 reflects $1.5 million in gains on sales of $14.3 million of SBA loans in the three months ended March 31, 2022, compared to no such sales in the three months ended March 31, 2023. There can be no assurance that Customers will realize gains from sales of loans in 2023 comparable to prior periods given the significant uncertainty in the capital markets.

Net gain (loss) on sale of investment securities

The $1.1 million decrease in net loss on sale of investment securities for the three months ended March 31, 2023 compared to the three months ended March 31, 2022 reflects net losses realized from the sale of $156.0 million in AFS debt securities during the three months ended March 31, 2022, compared to no such sales in the three months ended March 31, 2023. There can be no assurance that Customers will realize gains from sales of investment securities in 2023, given the significant uncertainty in the capital markets and fluctuations in our funding needs, which may impact Customers’ investment strategy.

Other non-interest income

The $0.9 million decrease in other non-interest income for the three months ended March 31, 2023 compared to the three months ended March 31, 2022 primarily resulted from decreases in unrealized gains on derivatives due to changes in market interest rates, mortgage banking and deposit fees, partially offset by increases in SERP income due to changes in capital markets and gains from the sales of commercial lease assets.

Technology, communication and bank operations

The $7.5 million decrease in technology, communication and bank operations expense for the three months ended March 31, 2023 compared to the three months ended March 31, 2022 primarily resulted from decreases in deposit servicing-related expenses resulting from lower servicing fees and the discontinuation of the interchange maintenance fees paid to BM Technologies pursuant to the amended deposit servicing agreement, partially offset by $2.7 million increase in higher software licenses, fees paid for software as a service and other processing and technology-related expenses.

Customers incurred expenses of $7.6 million and $17.8 million to BM Technologies under the deposit servicing agreement, included within the technology, communication and bank operations expense during the three months ended March 31, 2023 and 2022, respectively. As of March 31, 2023 and December 31, 2022, Customers held $1.1 billion of deposits serviced by BM Technologies. On March 22, 2023, Customers agreed to extend the deposit servicing agreement to the earlier of BM Technologies' successful completion of the transfer of the serviced deposits to a new sponsor bank or June 30, 2024. Customers expects that approximately $514 million of these serviced deposits held on March 31, 2023 in connection with BM Technologies' Higher Education business will leave Customers Bank by the earlier of BM Technologies' successful completion of the transfer of such deposits to a new sponsor bank or June 30, 2024. The remaining serviced deposits of approximately $569 million in connection with an existing white label relationship will remain at Customers Bank and continue to be serviced by BM Technologies, which was also renewed on March 22, 2023.

Commercial lease depreciation

The $2.9 million increase in commercial lease depreciation for the three months ended March 31, 2023 compared to the three months ended March 31, 2022 primarily resulted from the continued growth of the operating lease arrangements originated by Customers' Equipment Finance Group in which Customers is the lessor.

Professional services

The $0.6 million increase in professional services for the three months ended March 31, 2023 compared to the three months ended March 31, 2022 was primarily due to an increase in legal fees related to PPP related matters, partially offset by a decrease in outside professional services related to PPP forgiveness.

Loan servicing

The $2.3 million increase in loan servicing for the three months ended March 31, 2023 compared to the three months ended March 31, 2022 primarily resulted from the growth in loan portfolios serviced by third parties.

Advertising and promotion

The $0.7 million increase in advertising and promotion for the three months ended March 31, 2023 compared to the three months ended March 31, 2022 primarily resulted from higher spending on media and advertising agencies for our deposit products.

Other non-interest expense

The $1.4 million increase in other non-interest expense for the three months ended March 31, 2023 compared to the three months ended March 31, 2022 primarily resulted from increases in operating losses and a provision or addition to the reserve for unfunded commitments. A provision or addition to the reserve for unfunded commitments for the three months ended March 31, 2023 was $0.3 million, compared to a credit or release to the reserve for unfunded commitments of $0.1 million for the three months ended March 31, 2022.

Table of Contents

The $4.8 million decrease in income tax expense for the three months ended March 31, 2023, when compared to the same period in the prior year, primarily resulted from a decrease in pre-tax income and increased income tax credits. The increase in the effective tax rate for the three months ended March 31, 2023, when compared to the same period in the prior year, primarily resulted from lower death benefits from bank-owned life insurance policies and stock-based compensation benefits, partially offset by an increase in income tax credits.

PREFERRED STOCK DIVIDENDS

Preferred stock dividends were $3.5 million and $1.9 million for the three months ended March 31, 2023 and 2022, respectively. There were no changes to the amount of preferred stock outstanding during the three months ended March 31, 2023 and 2022.

The increase in total assets was primarily driven by increases of $1.6 billion in cash and cash equivalents, $95.7 million in loans held for sale and $30.0 million in investment securities held to maturity, partially offset by decreases of $751.9 million in loans receivable, PPP, $75.9 million in loans receivable, mortgage warehouse, at fair value and $60.5 million in investment securities, at fair value.

Cash and Cash Equivalents

Cash and cash equivalents include cash and due from banks and interest-earning deposits. Cash and due from banks consists mainly of vault cash and cash items in the process of collection. Cash and due from banks were $77.3 million and $58.0 million at March 31, 2023 and December 31, 2022, respectively. Cash and due from banks balances vary from day to day, primarily due to variations in customers’ deposit activities with the Bank.

Interest-earning deposits consist of cash deposited at other banks, primarily the FRB. Interest-earning deposits were $2.0 billion and $397.8 million at March 31, 2023 and December 31, 2022, respectively. The balance of interest-earning deposits varies from day to day, depending on several factors, such as fluctuations in customers' deposits with Customers, payment of checks drawn on customers' accounts and strategic investment decisions made to maximize Customers' net interest income, while effectively managing interest-rate risk and liquidity. The increase in interest-earning deposits from December 31, 2022 primarily resulted from maintaining a higher level of liquidity in response to heightened liquidity risk to the U.S. banking system, particularly to the regional banks.

Investment securities at fair value

The investment securities portfolio is an important source of interest income and liquidity. It consists primarily of mortgage-backed securities and collateralized mortgage obligations guaranteed by agencies of the United States government, asset-backed securities, collateralized loan obligations, commercial mortgage-backed securities, private label collateralized mortgage obligations, corporate notes and certain equity securities. In addition to generating revenue, the investment portfolio is maintained to manage interest-rate risk, provide liquidity, serve as collateral for other borrowings, and diversify the credit risk of interest-earning assets. The portfolio is structured to optimize net interest income given the changes in the economic environment, liquidity position and balance sheet mix.

At March 31, 2023, investment securities at fair value totaled $2.9 billion compared to $3.0 billion at December 31, 2022. The decrease primarily resulted from the maturities, calls and principal repayments totaling $69.6 million, partially offset by an increase in the fair value of AFS debt securities, or a decline in unrealized losses of $8.2 million due to changes in market interest rates for the three months ended March 31, 2023.

For financial reporting purposes, AFS debt securities are carried at fair value. Unrealized gains and losses on AFS debt securities, other than credit losses, are included in other comprehensive income (loss) and reported as a separate component of shareholders’ equity, net of the related tax effect. Changes in the fair value of equity securities with a readily determinable fair value and securities reported at fair value based on a fair value option election are recorded in non-interest income in the period in which they occur. Customers recorded a provision for credit losses of $1.6 million on certain asset-backed securities and corporate notes included in our investment securities at fair value during the three months ended March 31, 2023. Refer to "NOTE 5 – INVESTMENT SECURITIES" and "NOTE 13 – DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS" to Customers' unaudited consolidated financial statements for additional information.

The following table sets forth information about the maturities and weighted-average yield of the AFS debt securities portfolio. The weighted-average yield is computed based on a constant effective interest rate over the contractual life of each security adjusted for prepayment estimates, and considers the contractual coupon, amortization of premiums and accretion of discounts. Yields are not reported on a tax-equivalent basis. Yields exclude the impact of related hedging derivatives.

Investment securities held to maturity

At March 31, 2023, investment securities held to maturity totaled $870.3 million compared to $840.3 million at December 31, 2022. The increase in investment securities held to maturity resulted from a purchase of $73.1 million of private label collateralized mortgage obligations, partially offset by maturities, calls and principal repayments totaling $44.2 million for the three months ended March 31, 2023.

The following table sets forth information about the maturities and weighted-average yield of the investment securities held to maturity. The weighted-average yield is computed based on a constant effective interest rate over the contractual life of each security adjusted for prepayment estimates, and considers the contractual coupon, amortization of premiums, accretion of discounts and amortization of unrealized losses upon transfer from investment securities available for sale to held to maturity, along with the unrealized loss in accumulated other comprehensive income. Yields are not reported on a tax-equivalent basis.

Investment securities classified as HTM are those debt securities that Customers has both the intent and ability to hold to maturity regardless of changes in market conditions, liquidity needs, or changes in general economic conditions. For financial reporting purposes, these securities are carried at cost, adjusted for the amortization of premiums and accretion of discounts, computed by a method which approximates the interest method over the terms of the securities.

Loans receivable, mortgage warehouse, at fair value

The mortgage warehouse product line primarily provides financing to mortgage companies nationwide from the time of origination of the underlying mortgage loans until the mortgage loans are sold into the secondary market. As a mortgage warehouse lender, Customers provides a form of financing to mortgage bankers by purchasing for resale the underlying residential mortgages on a short-term basis under a master repurchase agreement. These loans are reported as loans receivable, mortgage warehouse, at fair value on the consolidated balance sheets. Because these loans are reported at their fair value, they do not have an ACL and are therefore excluded from ACL-related disclosures. At March 31, 2023, all of Customers' commercial mortgage warehouse loans were current in terms of payment.

Customers is subject to the risks associated with such lending, including, but not limited to, the risks of fraud, bankruptcy and default of the mortgage banker or of the underlying residential borrower, any of which could result in credit losses. Customers' mortgage warehouse lending team members monitor these mortgage originators by obtaining financial and other relevant information to reduce these risks during the lending period. Loans receivable, mortgage warehouse, at fair value totaled $1.2 billion and $1.3 billion at March 31, 2023 and December 31, 2022, respectively.

On June 30, 2022, one of Customers’ commercial mortgage warehouse borrowers filed for chapter 11 bankruptcy protection in the U.S. Bankruptcy Court for the District of Delaware. As of March 31, 2023, Customers had an outstanding loan balance with the borrower of $6.0 million in an unsecured working capital loan that was fully guaranteed by an affiliate of the primary shareholder of the borrower.

Loans receivable, PPP

Customers had $246.3 million and $998.2 million of PPP loans outstanding as of March 31, 2023 and December 31, 2022, respectively, which are fully guaranteed by the SBA, provided that the SBA's eligibility criteria are met and earn a fixed interest rate of 1.00%. Customers recognized interest income, including origination fees, of $23.6 million and $36.9 million for the three months ended March 31, 2023 and 2022, respectively.

Credit Risk

Customers manages credit risk by maintaining diversification in its loan and lease portfolio, establishing and enforcing prudent underwriting standards and collection efforts, and continuous and periodic loan and lease classification reviews. Management also considers the effect of credit risk on financial performance by reviewing quarterly and maintaining an adequate ACL. Credit losses are charged-off when they are identified, and provisions are added for current expected credit losses, to the ACL at least quarterly. The ACL is estimated at least quarterly.

The provision for credit losses on loans and leases was $18.0 million and $15.3 million for the three months ended March 31, 2023 and 2022, respectively. The ACL maintained for loans and leases receivable (excluding loans held for sale and loans receivable, mortgage warehouse, at fair value) was $130.3 million, or 0.97% of loans and leases receivable and 0.99% of loans and leases receivable, excluding PPP (a non-GAAP measure) at March 31, 2023, and $130.9 million or 0.93% of loans and leases receivable and 1.00% of loans and leases receivable, excluding PPP loans (a non-GAAP measure) at December 31, 2022. Excluding loans receivable, PPP from total loans and leases receivable is a non-GAAP measure. 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. Please refer to the reconciliation schedule below.

The decrease in the ACL resulted primarily from a decrease in consumer installment loans, partially offset by additional provision for credit losses from the recognition of weaker macroeconomic forecasts. Net charge-offs were $18.7 million for the three months ended March 31, 2023, an increase of $11.4 million compared to the same period in 2022. The increase in net charge-offs was primarily due to higher charge-offs for consumer installment loans. Installment charge-offs were attributable to unsecured consumer installment loans originated or purchased through arrangements with fintech companies and other market place lenders. Refer to the table of changes in Customers' ACL for annualized net-charge offs to average loans by loan type for the periods indicated.

The ACL is based on a quarterly evaluation of the loan and lease portfolio and is maintained at a level that management considers adequate to absorb expected losses as of the balance sheet date. 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. Refer to Critical Accounting Policies and Estimates herein and "NOTE 2 – SIGNIFICANT ACCOUNTING POLICIES AND BASIS OF PRESENTATION" to Customers' unaudited consolidated financial statements, also, refer to "NOTE 2 – SIGNIFICANT ACCOUNTING POLICIES AND BASIS OF PRESENTATION" to Customers' audited consolidated financial statements in its 2022 Form 10-K for further discussion on management's methodology for estimating the ACL.

Table of Contents

Approximately 42% 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 if principal repayment is expected to substantially come from the operation of the collateral or fair value of the collateral less estimated costs to sell if repayment of the loan is expected to be provided from the 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 product or other characteristic generally defining a shared characteristic with other loans or leases in the same group. Charge-offs from originated and acquired loans and leases are absorbed by the ACL. The schedule that follows includes both loans held for sale and loans held for investment.

DEPOSITS

Customers offers a variety of deposit accounts, including checking, savings, MMDA, and time deposits. Deposits are primarily obtained from Customers' geographic service area and nationwide through branchless digital banking, our white label relationship, deposit brokers, listing services and other relationships. Customers Bank provides TassatPayTM instant blockchain-based digital payments platform via CBITTM, which allows clients to make instant payments in U.S. dollars. CBIT may only be created by, transferred to and redeemed by commercial customers of Customers Bank on the instant B2B payments platform by maintaining U.S. dollars in deposit accounts at Customers Bank. As of March 31, 2023 and December 31, 2022, Customers Bank held $1.9 billion and $2.3 billion, respectively, of deposits from customers participating in CBIT, which are reported as deposit liabilities in the consolidated balance sheets. At March 31, 2023, substantially all the CBIT-related deposit accounts are non-interest bearing. Each CBIT is minted with precisely one U.S. dollar equivalent, and those dollars are held in a non-interest bearing omnibus deposit account until the CBIT is burned or redeemed. The number of CBIT outstanding in the CBIT instant payments platform is always equal to the U.S. dollars held in the omnibus deposit account at Customers Bank and is reported as a deposit liability in the consolidated balance sheet. The deposits from customers participating in CBIT include the omnibus deposit account established for the CBIT instant payments platform, which had an outstanding balance of $254.7 million and $23 thousand at March 31, 2023 and December 31, 2022, respectively.

The increase primarily resulted from increases of $50.3 million in retained earnings and $6.8 million in accumulated other comprehensive income (loss), net, partially offset by an increase of $39.8 million in treasury stock.

The increases in common stock and additional paid in capital resulted primarily from the issuance of common stock under share-based compensation arrangements for the three months ended March 31, 2023.

The increase in retained earnings resulted from net income of $53.7 million, partially offset by preferred stock dividends of $3.5 million for the three months ended March 31, 2023.

The increase in accumulated other comprehensive income (loss), net primarily resulted from a decrease of $8.3 million in unrealized losses on AFS debt securities and income tax effect of $2.1 million during the three months ended March 31, 2023.

The increase in treasury stock resulted from repurchase of 1,379,883 shares of common stock for $39.8 million pursuant to the Share Repurchase Program during the three months ended March 31, 2023. On August 25, 2021, the Board of Directors of Customers Bancorp authorized the Share Repurchase Program to repurchase up to 3,235,326 shares of the Company's common stock (representing 10% of the Company’s outstanding shares of common stock on June 30, 2021).

Purchases of shares under the Share Repurchase Program may be executed through open market purchases, privately negotiated transactions, through the use of Rule 10b5-1 plans, or otherwise. The exact number of shares, timing for such purchases, and the price and terms at and on which such purchases are to be made will be at the discretion of the Company and will comply with all applicable regulatory limitations.

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 that is sufficient to meet Customers' short-term and long-term needs, commitments and contractual obligations.

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 consolidated 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 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.

Customers recognized a provision for credit losses on unfunded lending-related commitments of $0.3 million during the three months ended March 31, 2023, resulting in an ACL of $3.3 million as of March 31, 2023. Customers had an ACL on unfunded lending-related commitments of $3.0 million as of December 31, 2022.

Customers Bank provides blockchain-based digital payments via CBIT, which allows clients to make instant payments in U.S. dollars. CBIT may only be created or minted by, transferred to and redeemed by commercial customers of Customers Bank on the instant B2B payments platform by maintaining U.S. dollars in deposit accounts at Customers Bank. CBIT is not listed or traded on any digital currency exchange. As of March 31, 2023 and December 31, 2022, Customers Bank held $1.9 billion and $2.3 billion, respectively, of deposits from customers participating in CBIT, which are reported as deposit liabilities in the consolidated balance sheets.

The CBIT instant payments platform provides a closed-system for intrabank commercial transactions and is not intended to be a trading platform for tokens or digital assets. CBIT tokens are used only in connection with the CBIT instant payments platform and are not securities for purposes of applicable securities laws. There are no scenarios in which the transaction or redemption value of one CBIT would not be equal to one U.S. dollar. Each CBIT is minted with precisely one U.S. dollar equivalent, and those dollars are held in a non-interest bearing omnibus deposit account until the CBIT is burned or redeemed. The number of CBIT outstanding in the CBIT instant payments platform is always equal to the U.S. dollars held in the omnibus deposit account at Customers Bank and is reported as a deposit liability in the consolidated balance sheet. The deposits from customers participating in CBIT include the omnibus deposit account, which had an outstanding balance of $254.7 million and $23 thousand at March 31, 2023 and December 31, 2022, respectively.

CAPITAL ADEQUACY

The Bank and the 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 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, the U.S federal banking regulatory agencies permitted banking organizations to phase-in, for regulatory capital purposes, the day-one impact of the new CECL accounting rule on retained earnings over a period of three years. As part of its response to the impact of COVID-19, on March 31, 2020, the U.S. federal banking regulatory agencies issued an interim final rule that provided the option to temporarily delay certain effects of CECL on regulatory capital for two years, followed by a three-year transition period. The interim final rule allows banking organizations to delay for two years 100% of the day-one impact of adopting CECL and 25% of the cumulative change in the reported allowance for credit losses since adopting CECL. Customers has elected to adopt the interim final rule, which is reflected in the regulatory capital data presented below. The cumulative CECL capital transition impact as of December 31, 2021 which amounted to $61.6 million will be phased in at 25% per year beginning on January 1, 2022 through December 31, 2024. As of March 31, 2023, our regulatory capital ratios reflected 50%, or $30.8 million, benefit associated with the CECL transition provisions.

In April 2020, the U.S. federal banking regulatory agencies issued an interim final rule that permits banks to exclude the impact of participating in the SBA PPP program in their regulatory capital ratios. Specifically, PPP loans are zero percent risk weighted and a bank can exclude all PPP loans pledged as collateral to the PPPLF from its average total consolidated assets for purposes of calculating the Tier 1 capital to average assets ratio (i.e. 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 March 31, 2023 and December 31, 2022, 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 Basel III Capital Rules require that we maintain a 2.500% capital conservation buffer with respect to each of common equity Tier 1, Tier 1 and total capital to risk-weighted assets, which provides for capital levels that exceed the minimum risk-based capital adequacy requirements. A financial institution with a capital 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. As of March 31, 2023, the Bank and the Bancorp were in compliance with the Basel III requirements.

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.

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 twelve months ending March 31, 2024 and December 31, 2023, based upon the assets, liabilities and off-balance sheet financial instruments in existence at March 31, 2023 and December 31, 2022. 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 March 31, 2023, current market interest rates were increased immediately by 100, 200, and 300 basis points. For downward rate shocks modeling a falling rate environment at March 31, 2023, current market interest rates were decreased immediately by 100, 200 and 300 basis points. The following table reflects the estimated percentage change in estimated net interest income for the twelve months ending March 31, 2024 and December 31, 2023, resulting from changes in interest rates.

Net change in net interest income

	% Change
Rate Shocks	March 31, 2023	December 31, 2022
Up 3%	14.2%	0.4%
Up 2%	9.5%	0.4%
Up 1%	5.1%	0.3%
Down 1%	(5.4)%	(0.9)%
Down 2%	(11.1)%	(2.0)%
Down 3%	(16.8)%	(4.8)%

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 March 31, 2023, current market interest rates were increased immediately by 100, 200, and 300 basis points. For downward rate shocks modeling a falling rate environment at March 31, 2023, current market interest rates were decreased immediately by 100, 200 and 300 basis points. 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 March 31, 2023 and December 31, 2022, resulting from shocks to interest rates.

	From Base
Rate Shocks	March 31, 2023	December 31, 2022
Up 3%	(2.2)%	(27.8)%
Up 2%	(0.4)%	(16.9)%
Up 1%	1.9%	(6.6)%
Down 1%	(6.6)%	0.0%
Down 2%	(37.2)%	(31.3)%
Down 3%	(64.1)%	(57.2)%

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.

LIBOR Transition

Customers has variable rate loans, investment securities, fixed-to-floating rate senior and subordinated debt, preferred stocks and derivatives that reference LIBOR. Various regulatory bodies have encouraged banks to transition away from LIBOR as soon as practicable, generally cease entering new contracts that use LIBOR as a reference rate no later than December 31, 2021, and for new contracts to utilize a reference rate other than LIBOR or include robust language that includes a clearly defined alternative reference rate after LIBOR’s discontinuation. Certain tenors of LIBOR have ceased publication and complete cessation of LIBOR publication is expected by June 30, 2023. Effective December 31, 2021, Customers has essentially discontinued entering into new LIBOR-based contracts. Customers established an enterprise-wide LIBOR transition program, which includes a LIBOR transition team with senior management level leadership. Progress on the LIBOR transition effort is monitored by executive management as well as the asset/liability committee of Customers' Board of Directors.

At March 31, 2023, Customers had LIBOR-based commercial loans and leases, commercial real estate loans and residential mortgages of $1.6 billion, which either mature before June 30, 2023 or have been amended to include appropriate alternative language to be effective upon cessation of LIBOR publication. In addition, $110.0 million of fixed-to-floating rate borrowings and $137.8 million of preferred equity instruments reference LIBOR. Customers' derivatives primarily reference LIBOR. In October 2020, the International Swaps and Derivatives Association, Inc. published the IBOR Fallbacks Supplement (“Supplement”) and the IBOR Fallback Protocol (“Protocol”). The Protocol enables market participants to incorporate certain revisions into their legacy non-cleared derivatives with other counterparties that also choose to adhere to the Protocol. Customers adhered to the IBOR Protocol in November 2020 and is in the process of remediating its interest rate swap transactions with its end-user customers. With respect to Customers' cleared interest rate swap agreements that reference LIBOR, clearinghouses have adopted the same relevant SOFR benchmark alternatives of the IBOR Supplement and IBOR Protocol. As loans mature and new originations occur a larger percentage of Customers' variable-rate loans are expected to reference SOFR. At March 31, 2023, the Company had approximately $4.4 billion of outstanding loan balances that reference SOFR. Customers’ usage of interest rate swap agreements referenced to SOFR is expected to increase in response to the discontinuation of LIBOR. Customers continues to work with its customers and other counterparties to remediate LIBOR-based agreements which expire after June 30, 2023 by incorporating alternative language, negotiating new agreements, or other means. The discontinuation of LIBOR and uncertainty relating to the emergence of one or more alternative benchmark indexes to replace LIBOR could materially impact the Customers’ interest rate risk profile and its management thereof. For a discussion of the risks associated with the LIBOR transition to alternative reference rates, refer to Part I, Item 1A. "Risk Factors" included in Customers' 2022 Form 10-K.

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 March 31, 2023.

(b) Changes in Internal Control Over Financial Reporting. During the quarter ended March 31, 2023, 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.

Part II. OTHER INFORMATION

Item 1. Legal Proceedings

For information on Customers' legal proceedings, refer to “NOTE 15 – LOSS CONTINGENCIES” to the unaudited consolidated financial statements.

Item 1A. Risk Factors

In addition to the other information set forth in this Quarterly Report, you should carefully consider the factors discussed in “Risk Factors” included within the 2022 Form 10-K. There are no material changes from the risk factors included within the 2022 Form 10-K, except as further discussed below. The risks described within the 2022 Form 10-K are not the only risks facing us. Additional risks and uncertainties not currently known to us or that we currently believe to be immaterial also may materially adversely affect our business, financial condition and/or operating results. Refer to “Item 2 – Management’s Discussion and Analysis of Financial Condition and Results of Operations – Cautionary Note Regarding Forward-Looking Statements.”

A continuation of recent turmoil in the financial services industry, and responsive measures to manage it, could have an adverse effect on our stock price, financial position and results of operations. In addition, if we are unable to adequately manage our liquidity, deposits, capital levels, interest rate risk or reputation risk, which have come under greater scrutiny in light of recent bank failures, it could have a material adverse effect on our stock price, financial condition and results of operations.

In recent months, several financial services institutions have failed or required outside liquidity support. The impact of this situation has led to market volatility and risk of additional stress to other financial services institutions and the financial services industry generally, in part as a result of increased lack of confidence in the financial services sector. While the U.S. Department of the Treasury, the Federal Reserve, and the FDIC have made statements regarding the safety and soundness of the banking system and taken actions, such as establishing the Bank Term Funding Program, as an additional source of liquidity for banks, there is no guarantee that such actions will be successful in restoring customer confidence. As a result of these events, certain of our customers chose, and may choose in the future, to withdraw deposit amounts in favor of keeping deposits at larger financial institutions that may be perceived to be more stable, or seek to switch their existing deposits into other higher yielding alternatives, any of which could materially adversely affect our liquidity, loan funding capacity, net interest margin, capital and results of operations.

In addition, these recent events may result in potentially adverse changes to laws or regulations governing banks and bank holding companies, increased oversight by regulatory authorities and/or the imposition of restrictions on certain business activities through supervisory or enforcement activities, including higher capital or liquidity requirements, which could have a material impact on our current and planned business. The cost of resolving the recent bank failures is also expected to result in action by the FDIC to increase its deposit insurance premiums or assessments.

These recent events also have led to a greater focus by regulators and investors on liquidity of existing assets and funding sources for financial institutions, the composition of deposits, including the amount of uninsured deposits, the amount of accumulated other comprehensive loss, capital levels and interest rate risk management. The increased influence of social media and other communication channels on the public perception of financial institutions and their operations can create reputation risk, which can adversely affect our stock price or the public’s perception of our stability or viability, even where such concerns are unwarranted. If we are unable to adequately manage our liquidity, deposits, capital levels, interest rate risk or reputation risk, it could have a material adverse effect on our stock price, financial condition, results of operations or regulatory standing.

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

Issuer Purchases of Equity Securities

On August 25, 2021, the Board of Directors of Customers Bancorp authorized the Share Repurchase Program to repurchase up to 3,235,326 shares of the Company's common stock (representing 10% of the Company’s outstanding shares of common stock on June 30, 2021). The term of the Share Repurchase Program was extended to September 27, 2023, unless earlier terminated. Purchases of shares under the Share Repurchase Program may be executed through open market purchases, privately negotiated transactions, through the use of Rule 10b5-1 plans, or otherwise. The exact number of shares, timing for such purchases, and the price and terms at and on which such purchases are to be made will be at the discretion of the Company and will comply with all applicable regulatory limitations. The common shares repurchased during the three months ended March 31, 2023 pursuant to the Share Repurchase Program were as follows:

Period	Total Number of Shares Purchased	Average Price Paid per Share		Total Number of Shares purchased as part of publicly announced plans or programs	Maximum Number of Shares that may yet be purchased under the plans or programs
January 1 - January 31, 2023	—	$	—	—	1,877,392
February 1 - February 28, 2023	1,013,283	31.48		1,013,283	864,109
March 1 - March 31, 2023	366,600	20.57		366,600	497,509
Total	1,379,883	$	28.58	1,379,883	497,509

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, 2022 consolidated balance sheet presented in this report has been derived from Customers Bancorp’s audited 2022 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 2022 consolidated financial statements of Customers Bancorp and subsidiaries included in Customers' Annual Report on Form 10-K for the year ended December 31, 2022 filed with the SEC on February 28, 2023 (the "2022 Form 10-K"). The 2022 Form 10-K describes Customers Bancorp’s significant accounting policies. There have been no material changes to Customers Bancorp's significant accounting policies noted above for the three months ended March 31, 2023.

Recently Issued 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 2022

Standard	Summary of Guidance	Effects on Financial Statements
ASU 2022-06, Reference Rate Reform (Topic 848) - Deferral of the Sunset Date of Topic 848 and Amendments to the Definition of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap Rate Issued December 2022	• Defers the sunset date of ASC 848 that provides optional guidance for a limited period of time to ease the potential burden in accounting for (or derecognizing the effects of) reference rate reform on financial reporting. Specifically, ASC 848 provides optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. These relate only to those contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. Certain optional expedients and exceptions in ASC 848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition, including derivative instruments that use an interest rate for margining, discounting, or contract price alignment that is modified as a result of reference rate reform. • Amends the definition of the SOFR Overnight Index Swap Rate to any rate based on SOFR qualifies as a benchmark interest rate for purposes of applying fair value hedge accounting. • Effective as of December 21, 2022 and ASC 848 can be adopted anytime during the period of January 1, 2020 through December 31, 2024.	• Customers adopted the guidance in ASC 848 during the adoption period for certain optional expedients. • The adoption of ASC 848 did not have a material impact on Customers' financial condition, results of operations and consolidated financial statements. • As of March 31, 2023, Customers has not yet elected to apply optional expedients for certain contract modifications. We plan to elect additional optional expedients in the future, which are not expected to have a material impact on Customers' financial condition, results of operations and consolidated financial statements.

Accounting Standards Adopted in 2023

Standard	Summary of Guidance	Effects on Financial Statements
ASU 2022-02, Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures Issued March 2022	• Eliminates the accounting guidance for TDRs by creditors, and applies the loan refinancing and restructuring guidance when a borrower is experiencing financial difficulty to determine whether a modification results in a new loan or a continuation of an existing loan. • Provides enhanced disclosure requirements for certain loan refinancing and restructurings and disclosure of current-period gross write-offs by year of origination for financing receivables and net investments in leases within the scope of ASC 326. • Effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years.

(1)Accrued interest on AFS debt securities totaled $19.6 million and $16.7 million at March 31, 2023 and December 31, 2022, respectively, and is included in accrued interest receivable on the consolidated balance sheet.

(2)Includes perpetual preferred stock issued by domestic banks and domestic bank holding companies and equity securities issued by fintech companies, without a readily determinable fair value, and CRA-qualified mutual fund shares at March 31, 2023 and December 31, 2022. No impairments or measurement adjustments have been recorded on the equity securities without a readily determinable fair value since acquisition.

Customers' transactions with unconsolidated VIEs include sales of consumer installment loans and investments in the securities issued by the VIEs. Customers is not the primary beneficiary of the VIEs because Customers has no right to make decisions that will most significantly affect the economic performance of the VIEs. Customers' continuing involvement with the unconsolidated VIEs is not significant. Customers' continuing involvement is not considered to be significant where Customers only invests in securities issued by the VIE and was not involved in the design of the VIE or where Customers has transferred financial assets to the VIE for only cash consideration. Customers' investments in the securities issued by the VIEs are classified as AFS or HTM debt securities on the consolidated balance sheets, and represent Customers' maximum exposure to loss.

There were no sales of AFS debt securities for the three months ended March 31, 2023. Proceeds from the sale of AFS debt securities were $156.0 million for the three months ended March 31, 2022. The following table presents gross realized gains and realized losses from the sale of AFS debt securities for the three months ended March 31, 2023 and 2022:

	Three Months Ended March 31,

Gross realized gains	$	—	$	974
Gross realized losses	—		(2,037)

These gains (losses) were determined using the specific identification method and were reported as net gain (loss) on sale of investment securities within non-interest income on the consolidated statements of income.

The following table presents AFS debt securities by stated maturity. Debt securities backed by mortgages and other assets have expected maturities that differ from contractual maturities because borrowers have the right to call or prepay and, therefore, these debt securities are classified separately with no specific maturity date:

At March 31, 2023, there were 50 AFS debt securities with unrealized losses in the less-than-twelve-months category and 112 AFS debt securities with unrealized losses in the twelve-months-or-more category. Except for the four asset-backed securities and six corporate notes where there was a deterioration in future estimated cash flows as further discussed below, the unrealized losses were principally due to changes in market interest rates that resulted in a negative impact on the respective securities' fair value and are expected to be recovered when market prices recover or at maturity. Customers does not intend to sell any of the 162 securities, and it is not more likely than not that Customers will be required to sell any of the 162 securities before recovery of the amortized cost basis. At December 31, 2022, there were 156 AFS debt securities in an unrealized loss position.

Customers recorded an allowance for credit losses on four asset-backed securities and six corporate notes where there was a deterioration in future estimated cash flows during the three months ended March 31, 2023 and on four asset-backed securities during the three months ended March 31, 2022. A discounted cash flow approach is used to determine the amount of the allowance. The cash flows expected to be collected, after considering expected prepayments, are discounted at the original effective interest rate. The amount of the allowance is limited to the difference between the amortized cost basis of the security and its estimated fair value.

The following tables present the activity in the allowance for credit losses on AFS debt securities, by major security type, for the periods presented:

	Three Months Ended March 31, 2023						Three Months Ended March 31, 2022

At March 31, 2023 and December 31, 2022, no securities holding of any one issuer, other than the U.S. government and its agencies, amounted to greater than 10% of shareholders' equity.

At March 31, 2023, Customers Bank had pledged AFS investment securities aggregating $1.6 billion in fair value as collateral for immediate available liquidity from FRB, including the BTFP. The counterparty does not have the ability to sell or repledge these securities.

Investment securities held to maturity

The amortized cost, approximate fair value and allowance for credit losses of investment securities held to maturity as of March 31, 2023 and December 31, 2022 are summarized as follows:

(1)Accrued interest on HTM debt securities totaled $1.5 million and $1.0 million at March 31, 2023 and December 31, 2022, respectively, and is included in accrued interest receivable on the consolidated balance sheet.

The following table presents HTM debt securities by stated maturity. Debt securities backed by mortgages and other assets have expected maturities that differ from contractual maturities because borrowers have the right to call or prepay and, therefore, these debt securities are classified separately with no specific maturity date:

	March 31, 2023
(amounts in thousands)	Amortized Cost		Fair Value
Asset-backed securities	$	322,877	$	319,735
Agency-guaranteed residential mortgage-backed securities	7,152		6,639

Private label collateralized mortgage obligations	186,407		176,917
Total held to maturity debt securities	$	870,294	$	836,713

Customers recorded no allowance for credit losses on investment securities classified as held to maturity at March 31, 2023 and December 31, 2022. The U.S. government agency securities represent obligations issued by a U.S. government-sponsored enterprise or other federal government agency that are explicitly or implicitly guaranteed by the U.S. federal government and therefore, assumed to have zero credit losses. Most of the private label collateralized mortgage obligations are highly rated and with sufficient overcollateralization, therefore have zero expected credit losses. Customers recorded no allowance for its investment in the asset-backed securities. Customers considered the seniority of its beneficial interest, which includes its overcollateralization of these asset-backed securities in the estimate of the ACL at March 31, 2023 and December 31, 2022. The unrealized losses on HTM debt securities with no ACL were due to changes in market interest rates that resulted in a negative impact on the respective securities' fair value and are expected to be recovered when market prices recover or at maturity.

Credit Quality Indicators

Customers monitors the credit quality of HTM debt securities primarily through credit ratings provided by rating agencies. Investment grade debt securities are rated BBB- or higher by S&P Global Ratings, Baa3 or higher by Moody's Investors Service or equivalent ratings by other rating agencies, and are generally considered to be of low credit risk. Except for the asset-backed securities and a private label collateralized mortgage obligation, all of the HTM debt securities held by Customers were investment grade or U.S. government agency guaranteed securities that were not rated at March 31, 2023 and December 31, 2022. The asset-backed securities and a private label collateralized mortgage obligation are not rated by rating agencies. Customers monitors the credit quality of these asset-backed securities and a private label collateralized mortgage obligation by evaluating the performance of the sold consumer installment loans and other underlying loans against the overcollateralization available for these securities.

The following table presents the amortized cost of HTM debt securities based on their lowest credit rating available:

	March 31, 2023

Customers has elected to not estimate an ACL on accrued interest receivable on HTM debt securities, as it already has a policy in place to reverse or write-off accrued interest, through interest income, for debt securities in nonaccrual status in a timely manner. At March 31, 2023 and December 31, 2022, there were no HTM debt securities past due under the terms of their agreements or in nonaccrual status.

At March 31, 2023 and December 31, 2022, Customers Bank had pledged HTM investment securities aggregating $443.8 million and $16.7 million in fair value, respectively, as collateral primarily for immediate available liquidity from FRB, including the BTFP and unused lines of credit with another financial institution. The counterparties do not have the ability to sell or repledge these securities.

(1)Includes direct finance equipment leases of $168.8 million and $157.4 million at March 31, 2023 and December 31, 2022, respectively.

(2)Includes deferred (fees) costs and unamortized (discounts) premiums, net of $(0.7) million and $(21.5) million at March 31, 2023 and December 31, 2022, respectively.

Customers' total loans and leases receivable 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, 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 $100.9 million and $105.5 million at March 31, 2023 and December 31, 2022, respectively, and is presented in accrued interest receivable in the consolidated balance sheet. At March 31, 2023 and December 31, 2022, there were $13.8 million and $11.5 million of individually evaluated loans that were collateral-dependent, respectively. Substantially all individually evaluated loans are collateral-dependent and consisted primarily of commercial and industrial, commercial real estate, and residential real estate loans. Collateral-dependent commercial and industrial loans were secured by accounts receivable, inventory and equipment; collateral-dependent commercial real estate loans were secured by commercial real estate assets; and residential real estate loans were secured by residential real estate assets.

Loans receivable, mortgage warehouse, at fair value

Mortgage warehouse loans consist of commercial loans to mortgage companies. These mortgage warehouse lending transactions are subject to master repurchase agreements. As a result of the contractual provisions, for accounting purposes, control of the underlying mortgage loan has not transferred and the rewards and risks of the mortgage loans are not assumed by Customers. The mortgage warehouse loans are designated as loans held for investment and reported at fair value based on an election made to account for the loans at fair value. Pursuant to the agreements, Customers funds the pipelines for these mortgage lenders by sending payments directly to the closing agents for funded mortgage loans and receives proceeds directly from third party investors when the underlying mortgage loans are sold into the secondary market. The fair value of the mortgage warehouse loans is estimated as the amount of cash initially advanced to fund the mortgage, plus accrued interest and fees, as specified in the respective agreements. The interest rates on these loans are variable, and the lending transactions are short-term, with an average life under 30 days from purchase to sale. The primary goal of these lending transactions is to provide liquidity to mortgage companies.

At March 31, 2023 and December 31, 2022, all of Customers' commercial mortgage warehouse loans were current in terms of payment. As these loans are reported at their fair value, they do not have an ACL and are therefore excluded from ACL-related disclosures.

Loans receivable, PPP

Customers had $246.3 million and $998.2 million of PPP loans outstanding as of March 31, 2023 and December 31, 2022, respectively, which are fully guaranteed by the SBA, provided that the SBA's eligibility criteria are met and earn a fixed interest rate of 1.00%. Customers recognized interest income, including net origination fees, of $23.6 million and $36.9 million for the three months ended March 31, 2023 and 2022, respectively.

PPP loans include an embedded credit enhancement from the SBA, which guarantees 100% of the principal and interest owed by the borrower provided that the SBA's eligibility criteria are met. As a result, the eligible PPP loans do not have an ACL and are therefore excluded from ACL-related disclosures.

(1) Includes specialty lending.

At March 31, 2023, the ACL on loans and leases was $130.3 million, a decrease of $0.6 million from the December 31, 2022 balance of $130.9 million. The decrease in ACL for the three months ended March 31, 2023 was primarily attributable to a decrease in consumer installment loans, partially offset by additional provision for credit losses from the recognition of weaker macroeconomic forecasts.

Loan Modifications for Borrowers Experiencing Financial Difficulty

Customers adopted ASU 2022-02, Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures ("ASU 2022-02") effective January 1, 2023. The amendments in ASU 2022-02 eliminated the recognition and measurement of TDRs and enhanced the disclosures for loan modifications to borrowers experiencing financial difficulty. Refer to NOTE 2 – SIGNIFICANT ACCOUNTING POLICIES AND BASIS OF PRESENTATION for additional information on the adoption.

A borrower is considered to be experiencing financial difficulty when there is a significant doubt about the borrower's ability to make the required principal and interest payments on the loan or to get an equivalent financing from another creditor at a market rate for a similar loan.

When borrowers are experiencing financial difficulty, Customers may make certain loan modifications as part of loss mitigation strategies to maximize expected payment. To be classified as a modification made to a borrower experiencing financial difficulty the modification must be in the form of an interest rate reduction, principal forgiveness, or an other-than-insignificant payment delay (payment deferral), term extension, or combinations thereof.

Customers will generally try other forms of relief before principal forgiveness but would define any contractual reduction in the amount of principal due without receiving payment or assets as forgiveness. For the purpose of this disclosure, Customers considers any contractual change in interest rate that results in a reduction in interest rate relative to the current stated interest rate as an interest rate reduction. Generally, Customers would consider any delay in payment of greater than 90 days in the last 12 months to be significant. Term extensions extend the original contractual maturity of the loan. For the purpose of this disclosure, modification of contingent payment features or covenants that would have accelerated payment are not considered term extensions.

The following table presents the amortized cost of loans that were modified to borrowers experiencing financial difficulty for the three months ended March 31, 2023, disaggregated by class of financing receivable and type of modification granted.

	Three Months Ended March 31, 2023
(dollars in thousands)	Term Extension		Payment Deferral		Debt Forgiveness		Interest Rate Reduction and Term Extension		Total		Percentage of Total by Financing Class
Commercial and industrial, including specialty lending	$	172	$	—	$	—	$	—	$	172	0.00	%
Commercial real estate owner occupied	169		—		—		—		169		0.02	%
Manufactured housing	7		—		—		63		70		0.16	%

Total	$	5,181	$	131	$	114	$	63	$	5,489

As of March 31, 2023, there were no commitments to lend additional funds to debtors experiencing financial difficulty whose loans have been modified during the three months ended March 31, 2023.

The following table summarizes the impacts of loan modifications made to borrowers experiencing financial difficulty for the three months ended March 31, 2023.

	Three Months Ended March 31, 2023
	Weighted Average
(dollars in thousands)	Interest Rate Reduction (%)	Term Extension (in months)	Payment Deferral (in months)	Debt Forgiven

Commercial real estate owner occupied	—	4	0	—
Manufactured housing	0.8	55	0	—
Personal installment	—	5	6	66

The performance of loans made to borrowers experiencing financial difficulty in which modifications were made is closely monitored to understand the effectiveness of modification efforts. Loans are considered to be in payment default at 90 days or more past due. The following table presents an aging analysis of loan modifications made to borrowers experiencing financial difficulty during the three months ended March 31, 2023.

	March 31, 2023
(dollars in thousands)	30-59 Days past due		60-89 Days past due		90 Days or more past due		Current		Total

Total	$	202	$	216	$	190	$	4,881	$	5,489

As of March 31, 2023, Customers did not have any loans that were made to borrowers experiencing financial difficulty during the three months ended March 31, 2023 that subsequently defaulted. Customers' ACL is influenced by loan level characteristics that inform the assessed propensity to default. As such, the provision for credit losses is impacted by changes in such loan level characteristics, such as payment performance. Loans made to borrowers experiencing financial difficulty can be classified as either accrual or nonaccrual.

Troubled Debt Restructuring

At December 31, 2022, there were $16.8 million in loans reported as TDRs. The following table presents loans modified by type of concession for the three months ended March 31, 2022. There were no modifications that involved forgiveness of debt for the three months ended March 31, 2022.

	Three Months Ended March 31, 2022
(dollars in thousands)	Number of loans	Recorded investment
Interest-rate reductions	10	$	346
Other (1)	32	451
Total	42	$	797

(1) Other includes covenant modifications, forbearance, loans discharged under Chapter 7 bankruptcy, or other concessions.

As of December 31, 2022, there were no commitments to lend additional funds to debtors whose loans have been modified in TDRs.

The following table presents, by loan type, the number of loans modified in TDRs and the related recorded investment, for which there was a payment default within twelve months following the modification.

	March 31, 2022
(dollars in thousands)	Number of loans	Recorded investment
Manufactured housing	1	$	49
Installment	23	276
Total loans	24	$	325

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.

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. Commercial and industrial including specialty lending, multifamily, owner occupied commercial real estate, non-owner occupied commercial real estate, and construction loans are rated based on an internally assigned risk rating system which is assigned at the time of loan origination and reviewed on a periodic, or on an “as needed” basis. Residential real estate, manufactured housing and installment loans are evaluated based on the payment activity of the loan.

To facilitate the monitoring of credit quality within the commercial and industrial including specialty lending, multifamily, owner occupied commercial real estate, non-owner occupied commercial real estate, and construction loan portfolios, and as an input in the ACL lifetime loss rate model for the commercial and industrial loan portfolio, the Bank utilizes the following categories of risk ratings: pass/satisfactory (includes risk rating 1 through 6), special mention, substandard, doubtful, and loss. The risk rating categories, which are derived from standard regulatory rating definitions, are assigned upon initial approval of credit to borrowers and updated periodically thereafter. Pass ratings, which are assigned to those borrowers who do not have identified potential or well-defined weaknesses and for whom there is a high likelihood of orderly repayment, are updated periodically based on the size and credit characteristics of the borrower. All other categories are updated on a quarterly basis during the month preceding the end of the calendar quarter. While assigning risk ratings involves judgment, the risk-rating process allows management to identify riskier credits in a timely manner and allocate the appropriate resources to manage those loans and leases. The 2022 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 and current period gross write-offs as of March 31, 2023 and December 31, 2022.

LEASES

Lessee

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

As most of Customers' operating leases do not provide an implicit rate, Customers utilized its incremental borrowing rate when determining the present value of lease payments.

Equipment Lessor

CCF is a wholly-owned subsidiary of Customers Bank and is referred to as the Equipment Finance Group. The Equipment Finance Group goes to market through the following origination platforms: vendors, intermediaries, direct and capital markets. The Equipment Finance Group is primarily focused on serving the following segments: transportation, construction (includes crane and utility), marine, franchise, general manufacturing (includes machine tool), helicopter/fixed wing, solar, packaging, plastics and food processing. Lease terms typically range from 24 months to 120 months. The Equipment Finance Group offers the following products: Loans, Capital Lease, PUT, 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 ACL on loans and leases.

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

Leases

LEASES

Lessee

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

As most of Customers' operating leases do not provide an implicit rate, Customers utilized its incremental borrowing rate when determining the present value of lease payments.

Equipment Lessor

CCF is a wholly-owned subsidiary of Customers Bank and is referred to as the Equipment Finance Group. The Equipment Finance Group goes to market through the following origination platforms: vendors, intermediaries, direct and capital markets. The Equipment Finance Group is primarily focused on serving the following segments: transportation, construction (includes crane and utility), marine, franchise, general manufacturing (includes machine tool), helicopter/fixed wing, solar, packaging, plastics and food processing. Lease terms typically range from 24 months to 120 months. The Equipment Finance Group offers the following products: Loans, Capital Lease, PUT, 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 ACL on loans and leases.

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

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, the U.S federal banking regulatory agencies permitted banking organizations to phase-in, for regulatory capital purposes, the day-one impact of the new CECL accounting rule on retained earnings over a period of three years. As part of its response to the impact of COVID-19, on March 31, 2020, the U.S. federal banking regulatory agencies issued an interim final rule that provided the option to temporarily delay certain effects of CECL on regulatory capital for two years, followed by a three-year transition period. The interim final rule allows banking organizations to delay for two years 100% of the day-one impact of adopting CECL and 25% of the cumulative change in the reported allowance for credit losses since adopting CECL. Customers has elected to adopt the interim final rule, which is reflected in the regulatory capital data presented below. The cumulative CECL capital transition impact as of December 31, 2021 which amounted to $61.6 million will be phased in at 25% per year beginning on January 1, 2022 through December 31, 2024. As of March 31, 2023, our regulatory capital ratios reflected 50%, or $30.8 million, benefit associated with the CECL transition provisions.

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

Quantitative measures established by regulation to ensure capital adequacy require the Bank and the Bancorp to maintain minimum amounts and ratios (set forth in the following table) of common equity Tier 1, Tier 1, and total capital to risk-weighted assets, and Tier 1 capital to average assets (as defined in the regulations). At March 31, 2023 and December 31, 2022, 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:

Fair Value Disclosures [Abstract]

Disclosures About Fair Value of Financial Instruments

DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTSCustomers uses fair value measurements to record fair value adjustments to certain assets and liabilities and to disclose the fair value of its financial instruments. ASC 825, Financial Instruments, requires disclosure of the estimated fair value of an entity’s assets and liabilities considered to be financial instruments. For Customers, as for most financial institutions, the majority of its assets and liabilities are considered to be financial instruments. Many of these instruments lack an available trading market as characterized by a willing buyer and a willing seller engaging in an exchange transaction. For fair value disclosure purposes, Customers utilized certain fair value measurement criteria under ASC 820, Fair Value Measurements and Disclosures ("ASC 820"), as explained below.

In accordance with ASC 820, the fair value of a financial instrument is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is best determined based upon quoted market prices. However, in many instances, there are no quoted market prices for Customers' various financial instruments. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. Accordingly, the fair value estimates may not be realized in an immediate settlement of the instrument.

The fair value guidance provides a consistent definition of fair value, focusing on an exit price in an orderly transaction (that is, not a forced liquidation or distressed sale) between market participants at the measurement date under current market conditions. If there has been a significant decrease in the volume and level of activity for the asset or liability, a change in valuation technique or the use of multiple valuation techniques may be appropriate. In such instances, determining the price at which willing market participants would transact at the measurement date under current market conditions depends on the facts and circumstances and requires the use of significant judgment. The fair value is a reasonable point within the range that is most representative of fair value under current market conditions.

The fair value guidance also establishes a fair value hierarchy and describes the following three levels used to classify fair value measurements.

Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.

Level 2: Quoted prices in markets that are not active, or inputs that are observable either directly or indirectly, for substantially the full term of the asset or liability.

Level 3: Prices or valuation techniques that require adjustments to inputs that are both significant to the fair value measurement and unobservable (i.e., supported with little or no market activity).

A financial instrument’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement.

The following methods and assumptions were used to estimate the fair values of Customers' financial instruments as of March 31, 2023 and December 31, 2022:

Financial Instruments Recorded at Fair Value on a Recurring Basis

Investment securities:

The fair values of equity securities with a readily determinable fair value, AFS debt securities and debt securities reported at fair value based on a fair value option election are determined by obtaining quoted market prices on nationally recognized and foreign securities exchanges (Level 1), quoted prices in markets that are not active (Level 2), matrix pricing (Level 2), which is a mathematical technique used widely in the industry to value debt securities without relying exclusively on quoted market prices for the specific securities but rather by relying on the securities’ relationship to other benchmark quoted prices, or internally and externally developed models that use unobservable inputs due to limited or no market activity of the instrument (Level 3).

When quoted market prices are not available, Customers employs an independent pricing service that utilizes matrix pricing to calculate fair value. Such fair value measurements consider observable data such as dealer quotes, market spreads, cash flows, yield curves, live trading levels, trade execution data, market consensus prepayments speeds, credit information, and respective terms and conditions for debt instruments. Management maintains procedures to monitor the pricing service's results and has an established process to challenge their valuations, or methodologies, that appear unusual or unexpected.

Customers also utilizes internally and externally developed models that use unobservable inputs due to limited or no market activity of the instrument. These models use unobservable inputs that are inherently judgmental and reflect our best estimates of the assumptions a market participant would use to calculate fair value. Certain unobservable inputs in isolation may have either a directionally consistent or opposite impact on the fair value of the instrument for a given change in that input. When multiple inputs are used within the valuation techniques, a change in one input in a certain direction may be offset by an opposite change from another input. These assets are classified as Level 1, 2 or 3 fair values, based upon the lowest level of input that is significant to the fair value measurements.

Loans held for sale - Residential mortgage loans (fair value option):

Customers generally estimates the fair values of residential mortgage loans held for sale based on commitments on hand from investors within the secondary market for loans with similar characteristics. These assets are classified as Level 2 fair values, based upon the lowest level of input that is significant to the fair value measurements.

Loans receivable - Commercial mortgage warehouse loans (fair value option):

The fair value of commercial mortgage warehouse loans is the amount of cash initially advanced to fund the mortgage, plus accrued interest and fees, as specified in the respective agreements. The loan is used by mortgage companies as short-term bridge financing between the funding of the mortgage loans and the finalization of the sale of the loans to an investor. Changes in fair value are not generally expected to be recognized because at inception of the transaction the underlying mortgage loans have already been sold to an approved investor. Additionally, the interest rate is variable, and the transaction is short-term, with an average life of under 30 days from purchase to sale. These assets are classified as Level 2 fair values, based upon the lowest level of input that is significant to the fair value measurements.

Derivatives (assets and liabilities):

The fair values of interest rate swaps, interest rate caps and credit derivatives are determined using models that incorporate readily observable market data into a market standard methodology. This methodology nets the discounted future cash receipts and the discounted expected cash payments. The discounted variable cash receipts and payments are based on expectations of future interest rates derived from observable market interest rate curves. In addition, fair value is adjusted for the effect of nonperformance risk by incorporating credit valuation adjustments for Customers and its counterparties. These assets and liabilities are classified as Level 2 fair values, based upon the lowest level of input that is significant to the fair value measurements.

The fair values of the residential mortgage loan commitments are derived from the estimated fair values that can be generated when the underlying mortgage loan is sold in the secondary market. Customers generally uses commitments on hand from third party investors to estimate an exit price and adjusts for the probability of the commitment being exercised based on Customers' internal experience (i.e., pull-through rate). These assets and liabilities are classified as Level 3 fair values, based upon the lowest level of input that is significant to the fair value measurements.

Derivative assets and liabilities are presented in other assets and accrued interest payable and other liabilities on the consolidated balance sheet.

Financial Instruments Recorded at Fair Value on a Nonrecurring Basis

Collateral-dependent loans:

Collateral-dependent loans are those loans that are accounted for under ASC 326, Financial Instruments - Credit Losses ("ASC 326"), in which the Bank has measured impairment generally based on the fair value of the loan’s collateral or DCF analysis. Fair value is generally determined based upon independent third-party appraisals of the properties that collateralize the loans, DCF based upon the expected proceeds, sales agreements or letters of intent with third parties. These assets are generally classified as Level 3 fair values, based upon the lowest level of input that is significant to the fair value measurements.

The following information should not be interpreted as an estimate of Customers' fair value in its entirety because fair value calculations are only provided for a limited portion of Customers' assets and liabilities. Due to a wide range of valuation techniques and the degree of subjectivity used in making these estimates, comparisons between Customers' disclosures and those of other companies may not be meaningful.

The estimated fair values of Customers' financial instruments at March 31, 2023 and December 31, 2022 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 an accommodation provided to certain qualifying customers, and therefore, they are not used to manage Customers’ interest-rate risk in assets or liabilities. Customers manages a matched book with respect to its derivative instruments used in this customer service in order to minimize its net risk exposure resulting from such transactions.

Fair Value Hedges of Benchmark Interest-Rate Risk

Customers is exposed to changes in the fair value of certain of its fixed rate AFS debt securities, deposits and FHLB advances due to changes in the benchmark interest rate. Customers uses interest rate swaps to manage its exposure to changes in fair value on these instruments attributable to changes in the designated benchmark interest rate such as the Fed Funds Effective Swap Rate. Interest rate swaps designated as fair value hedges of certain of its fixed rate AFS debt securities involve the payment of fixed-rate amounts to a counterparty in exchange for Customers receiving variable-rate payments over the life of the agreements without the exchange of the underlying notional amount. Interest rate swaps designated as fair value hedges of certain deposits and FHLB advances involve the payment of variable-rate amounts to a counterparty in exchange for Customers receiving fixed-rate payments over the life of the agreements without the exchange of the underlying notional amount. For derivatives designated and that qualify as fair value hedges, the gain or loss on the derivative as well as the offsetting loss or gain on the hedged item attributable to the hedged risk are recognized in net interest income.

At March 31, 2023, Customers had three outstanding interest rate derivatives with notional amounts totaling $22.5 million that were designated as fair value hedges of certain AFS debt securities. During the three months ended March 31, 2023, Customers entered into, and terminated two interest rate derivatives with notional amounts totaling $550.0 million that were designated as fair value hedges of certain deposits and FHLB advances resulting in $4.6 million of basis adjustments which will be amortized over the remaining terms of the hedged items as a reduction in interest expense. During the three months ended March 31, 2022, Customers terminated two interest rate derivatives with notional amounts totaling $16.5 million that were designated as fair value hedges together with the sale of hedged AFS debt securities. At December 31, 2022, Customers had three outstanding interest rate derivatives with notional amounts totaling $22.5 million designated as fair value hedges of certain AFS debt securities.

As of March 31, 2023 and December 31, 2022, the following amounts were recorded on the consolidated balance sheet related to cumulative basis adjustments for fair value hedges.

Derivatives Not Designated as Hedging Instruments

Customers executes interest rate swaps (typically the loan customers will swap a floating-rate loan for a fixed-rate loan) and interest rate caps with commercial banking customers to facilitate their respective risk management strategies. The customer interest rate swaps and interest rate caps are simultaneously offset by interest rate swaps and interest rate caps that Customers executes with a third party in order to minimize interest-rate risk exposure resulting from such transactions. As the interest rate swaps and interest rate caps associated with this program do not meet the hedge accounting requirements, changes in the fair value of both the customer swaps and caps and the offsetting third-party market swaps and caps are recognized directly in earnings. At March 31, 2023, Customers had 139 interest rate swaps with an aggregate notional amount of $1.3 billion and 12 interest rate caps with an aggregated notional amount of $244.6 million related to this program. At December 31, 2022, Customers had 141 interest rate swaps with an aggregate notional amount of $1.3 billion and 12 interest rate caps with an aggregate notional amount of $245.8 million related to this program.

Customers enters into residential mortgage loan commitments in connection with its consumer mortgage banking activities to fund mortgage loans at specified rates and times in the future. These commitments are short-term in nature and generally expire in 30 to 60 days. The residential mortgage loan commitments that relate to the origination of mortgage loans that will be held for sale are considered derivative instruments under applicable accounting guidance and are reported at fair value, with changes in fair value recorded directly in earnings. At March 31, 2023 and December 31, 2022, Customers had an aggregate notional amount of residential mortgage loan commitments of $3.3 million and $1.5 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 recorded directly in earnings. At March 31, 2023 and December 31, 2022, Customers had an aggregate notional amount of credit derivatives of $123.5 million and $142.0 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 or with central clearing parties.

Agreements with major derivative dealer counterparties contain provisions whereby default on any of Customers' indebtedness would be considered a default on its derivative obligations. Customers also has entered into agreements that contain provisions under which the counterparty could require Customers to settle its obligations if Customers fails to maintain its status as a well/adequately capitalized institution. As of March 31, 2023, the fair value of derivatives in a net asset position (which includes accrued interest but excludes any adjustment for nonperformance-risk) related to these agreements was $21.0 million. In addition, Customers, which has collateral posting thresholds with certain of these counterparties, had received $23.0 million of cash as collateral at March 31, 2023. Customers records cash posted or received as collateral with these counterparties, except with a central clearing entity, as a reduction or an increase in the outstanding balance of cash and cash equivalents and an increase in the balance of other assets or other liabilities.

Commitments and Contingencies Disclosure [Abstract]
Loss Contingencies	LOSS CONTINGENCIESLoss 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.

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, 2022 consolidated balance sheet presented in this report has been derived from Customers Bancorp’s audited 2022 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 2022 consolidated financial statements of Customers Bancorp and subsidiaries included in Customers' Annual Report on Form 10-K for the year ended December 31, 2022 filed with the SEC on February 28, 2023 (the "2022 Form 10-K"). The 2022 Form 10-K describes Customers Bancorp’s significant accounting policies. There have been no material changes to Customers Bancorp's significant accounting policies noted above for the three months ended March 31, 2023.

ASU 2022-06, Reference Rate Reform (Topic 848) - Deferral of the Sunset Date of Topic 848 and Amendments to the Definition of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap Rate Issued December 2022	• Defers the sunset date of ASC 848 that provides optional guidance for a limited period of time to ease the potential burden in accounting for (or derecognizing the effects of) reference rate reform on financial reporting. Specifically, ASC 848 provides optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. These relate only to those contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. Certain optional expedients and exceptions in ASC 848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition, including derivative instruments that use an interest rate for margining, discounting, or contract price alignment that is modified as a result of reference rate reform. • Amends the definition of the SOFR Overnight Index Swap Rate to any rate based on SOFR qualifies as a benchmark interest rate for purposes of applying fair value hedge accounting. • Effective as of December 21, 2022 and ASC 848 can be adopted anytime during the period of January 1, 2020 through December 31, 2024.	• Customers adopted the guidance in ASC 848 during the adoption period for certain optional expedients. • The adoption of ASC 848 did not have a material impact on Customers' financial condition, results of operations and consolidated financial statements. • As of March 31, 2023, Customers has not yet elected to apply optional expedients for certain contract modifications. We plan to elect additional optional expedients in the future, which are not expected to have a material impact on Customers' financial condition, results of operations and consolidated financial statements.

ASU 2022-02, Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures Issued March 2022	• Eliminates the accounting guidance for TDRs by creditors, and applies the loan refinancing and restructuring guidance when a borrower is experiencing financial difficulty to determine whether a modification results in a new loan or a continuation of an existing loan. • Provides enhanced disclosure requirements for certain loan refinancing and restructurings and disclosure of current-period gross write-offs by year of origination for financing receivables and net investments in leases within the scope of ASC 326. • Effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Early adoption is permitted, including adoption in any interim period, provided the amendments are adopted as of the beginning of the fiscal year that includes the interim period of adoption. Early adoption is permitted separately for the amendments to TDRs and vintage disclosures. • TDR and vintage disclosures are to be adopted prospectively. An entity may adopt TDR recognition and measurement guidance prospectively or elect to use a modified retrospective transition method, with a cumulative effect adjustment to retained earnings at the beginning of the period of adoption.	• Customers adopted this guidance on January 1, 2023 using a modified retrospective transition method for TDR recognition and measurement. • This guidance did not have a material impact on Customers' financial condition, results of operations and consolidated financial statements. • Additional disclosures related to gross write-offs by year of origination and certain loan modifications to borrowers experiencing financial difficulty are presented in NOTE 7 – LOANS AND LEASES RECEIVABLE AND ALLOWANCE FOR CREDIT LOSSES ON LOANS AND LEASES.

This guidance is not expected to have a material impact on Customers' financial condition, results of operations and consolidated financial statements.

Variable Interest Entity

Customers' transactions with unconsolidated VIEs include sales of consumer installment loans and investments in the securities issued by the VIEs. Customers is not the primary beneficiary of the VIEs because Customers has no right to make decisions that will most significantly affect the economic performance of the VIEs. Customers' continuing involvement with the unconsolidated VIEs is not significant. Customers' continuing involvement is not considered to be significant where Customers only invests in securities issued by the VIE and was not involved in the design of the VIE or where Customers has transferred financial assets to the VIE for only cash consideration. Customers' investments in the securities issued by the VIEs are classified as AFS or HTM debt securities on the consolidated balance sheets, and represent Customers' maximum exposure to loss.

Fair Value Measurement

Customers uses fair value measurements to record fair value adjustments to certain assets and liabilities and to disclose the fair value of its financial instruments. ASC 825, Financial Instruments, requires disclosure of the estimated fair value of an entity’s assets and liabilities considered to be financial instruments. For Customers, as for most financial institutions, the majority of its assets and liabilities are considered to be financial instruments. Many of these instruments lack an available trading market as characterized by a willing buyer and a willing seller engaging in an exchange transaction. For fair value disclosure purposes, Customers utilized certain fair value measurement criteria under ASC 820, Fair Value Measurements and Disclosures ("ASC 820"), as explained below.

In accordance with ASC 820, the fair value of a financial instrument is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is best determined based upon quoted market prices. However, in many instances, there are no quoted market prices for Customers' various financial instruments. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. Accordingly, the fair value estimates may not be realized in an immediate settlement of the instrument.

The fair value guidance provides a consistent definition of fair value, focusing on an exit price in an orderly transaction (that is, not a forced liquidation or distressed sale) between market participants at the measurement date under current market conditions. If there has been a significant decrease in the volume and level of activity for the asset or liability, a change in valuation technique or the use of multiple valuation techniques may be appropriate. In such instances, determining the price at which willing market participants would transact at the measurement date under current market conditions depends on the facts and circumstances and requires the use of significant judgment. The fair value is a reasonable point within the range that is most representative of fair value under current market conditions.

The fair value guidance also establishes a fair value hierarchy and describes the following three levels used to classify fair value measurements.

Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.

Level 2: Quoted prices in markets that are not active, or inputs that are observable either directly or indirectly, for substantially the full term of the asset or liability.

Level 3: Prices or valuation techniques that require adjustments to inputs that are both significant to the fair value measurement and unobservable (i.e., supported with little or no market activity).

A financial instrument’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement.

Derivatives

Risk Management Objectives of Using Derivatives

Customers is exposed to certain risks arising from both its business operations and economic conditions. Customers manages economic risks, including interest rate, liquidity and credit risk, primarily by managing the amount, sources, and durations of its assets and liabilities. Specifically, Customers enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the values of which are determined by interest rates. Customers’ derivative financial instruments are used to manage differences in the amount, timing, and duration of Customers’ known or expected cash receipts and its known or expected cash payments principally related to certain borrowings and deposits. Customers also has interest-rate derivatives resulting from an accommodation provided to certain qualifying customers, and therefore, they are not used to manage Customers’ interest-rate risk in assets or liabilities. Customers manages a matched book with respect to its derivative instruments used in this customer service in order to minimize its net risk exposure resulting from such transactions.
