In 1986, Bryn Mawr Bank Corporation (“BMBC”) was formed and on January 2, 1987, the Bank became a wholly-owned subsidiary of BMBC. The Bank and BMBC are headquartered in Bryn Mawr, Pennsylvania, located in the western suburbs of Philadelphia. BMBC and its direct and indirect subsidiaries (collectively, the “Corporation”) offer a full range of personal and business banking services, consumer and commercial loans, equipment leasing, mortgages, insurance and wealth management services, including investment management, trust and estate administration, retirement planning, custody services, and tax planning and preparation from 41 banking locations, seven wealth management offices and two insurance and risk management locations in the following counties: Montgomery, Chester, Delaware, Philadelphia, and Dauphin Counties in Pennsylvania; New Castle County in Delaware; and Mercer and Camden Counties in New Jersey. The common stock of BMBC trades on the NASDAQ Stock Market (“NASDAQ”) under the symbol BMTC. The Bank’s subsidiary, BMT Insurance Advisors, Inc., completed the acquisition of Domenick, a full-service insurance agency established in 1993 and headquartered in Philadelphia, on May 1, 2018. The consideration paid was $1.5 million, of which $750 thousand was paid at closing, $225 thousand was paid during the third quarter of 2019, $175 thousand was paid during the second quarter of 2020 and one contingent cash payment, not to exceed $250 thousand, will be payable in 2021, subject to the attainment of certain targets during the year. On December 15, 2017, the previously announced merger of Royal Bancshares of Pennsylvania, Inc. (“RBPI”) with and into BMBC (the “Effective Date”), and the merger of Royal Bank America with and into the Bank (collectively, the "RBPI Merger"), pursuant to the Agreement and Plan of Merger, by and between RBPI and BMBC, dated as of January 30, 2017 (the “Agreement”) was completed. Consideration paid totaled $138.7 million, comprised of 3,101,316 shares of BMBC's common stock, the assumption of 140,224 warrants to purchase BMBC's common stock valued at $1.9 million, $112 thousand for the cash-out of certain options and $7 thousand of cash in lieu of fractional shares. The RBPI Merger initially added $570.4 million of loans, $121.6 million of investments, $593.2 million of deposits, and twelve new branches. The acquisition of RBPI expands the Corporation further into Montgomery, Chester, Berks and Philadelphia Counties in Pennsylvania as well as Mercer and Camden Counties in New Jersey. The Corporation operates in a highly competitive market area that includes local, national and regional banks as competitors along with savings banks, credit unions, insurance companies, trust companies, registered investment advisors and mutual fund families. The Corporation and its subsidiaries are regulated by many regulatory agencies including the Securities and Exchange Commission (“SEC”), Federal Deposit Insurance Corporation (“FDIC”), the Board of Governors of the Federal Reserve System (the “Federal Reserve Board”) and the Pennsylvania Department of Banking. B. Basis of Presentation and Principles of Consolidation The accounting policies of the Corporation conform to U.S. generally accepted accounting principles (“GAAP”). The Consolidated Financial Statements include the accounts of BMBC and its consolidated subsidiaries. BMBC’s primary subsidiary is the Bank. The Corporation’s consolidated financial condition and results of operations consist almost entirely of the Bank’s financial condition and results of operations. In connection with the RBPI Merger, the Corporation acquired two Delaware trusts, Royal Bancshares Capital Trust I and Royal Bancshares Capital Trust II. These two entities are not consolidated per requirements under Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 810, “Consolidation” (“ASC Topic 810”). All significant intercompany balances and transactions are eliminated in consolidation and certain reclassifications are made when necessary in order to conform the previous years' consolidated financial statements to the current year's presentation. In preparing the Consolidated Financial Statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the dates of the balance sheets, and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from these estimates. Although our current estimates contemplate current conditions and how we expect them to change in the future, it is reasonably possible that in 2021 actual conditions could be worse than anticipated in those estimates, which could materially affect our results of operations and financial condition. The Corporation has identified certain areas that require estimates and assumptions, which include the allowance for credit losses (“ACL”) on loans and leases, the ACL on Off-Balance Sheet (“OBS”) Credit Exposures, the valuation of goodwill and intangible assets, the fair value of investment securities, the fair value of derivative financial instruments, and the valuation of mortgage servicing rights, deferred tax assets and liabilities, benefit plans and stock-based compensation. In addition, certain assets are measured at fair value on a nonrecurring basis; that is, the instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances. C. Cash and Cash Equivalents Cash and cash equivalents include cash, interest-bearing and noninterest-bearing amounts due from banks, and federal funds sold. The Bank maintains cash reserve balances as required to meet regulatory reserve requirements of the Federal Reserve Board. The Bank had no cash reserve balances at December 31, 2020 as the Federal Reserve Board reduced the requirements to zero. Cash balances required to meet regulatory reserve requirements of the Federal Reserve Board amounted to $24.6 million at December 31, 2019. D. Investment Securities Investment securities which are held for indefinite periods of time, which the Corporation intends to use as part of its asset/liability strategy, or which may be sold in response to changes in credit quality of the issuer, interest rates, changes in prepayment risk, increases in capital requirements, or other similar factors, are classified as available for sale and are carried at fair value. Net unrealized gains and losses for such securities, net of tax, are required to be recognized as a separate component of shareholders’ equity and excluded from determination of net income. Gains or losses on disposition are based on the net proceeds and cost of the securities sold, adjusted for the amortization of premiums and accretion of discounts, using the specific identification method. Investments for which management has the intent and ability to hold until maturity are classified as held to maturity and are carried at their amortized cost on the balance sheet. No adjustment for market value fluctuations are recorded related to the held to maturity portfolio. Investment securities held in trading accounts consist of deferred compensation trust accounts, which are invested in listed mutual funds whose diversification is at the discretion of the deferred compensation plan participants. Investment securities held in trading accounts are reported at fair value, with adjustments in fair value reported through income. E. ACL on Available for Sale Securities For available for sale debt securities in an unrealized loss position, management first assesses whether it intends to sell, or it is more likely than not it will be required to sell the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the security’s amortized cost basis is written down to fair value through income. For available for sale debt securities that do not meet the aforementioned criteria, management evaluates whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, management considers the extent to which fair value is less than amortized cost, any explicit or implicit guarantees by the U.S. government, any changes to the rating of the security by the rating agency, and adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost basis. Any impairment that has not been recorded through an allowance for credit loss is recognized in other comprehensive income. Changes in the ACL on available for sale debt securities are recorded as provision for (or release of) credit loss expense. Losses are charged against the ACL on available for sale debt securities when management believes the uncollectibility of an available for sale security is confirmed or when either of the criteria regarding intent or requirement to sell is met. Accrued interest receivable on available for sale debt securities, which is reported in Accrued interest receivable on the Consolidated Balance Sheet, totaled $2.0 million at December 31, 2020 and is excluded from the estimate of credit losses. F. ACL on Held to Maturity Securities Management measures expected credit losses on held to maturity debt securities on a collective basis by major security type. The Corporation’s held to maturity debt securities consist of mortgage-backed securities issued by U.S. government entities and agencies. These securities are either explicitly or implicitly guaranteed by the U.S. government, are highly rated by major rating agencies and have a long history of no credit losses. With respect to these securities, management considers the history of credit losses, current conditions and reasonable and supportable forecasts, which may indicate that the expectation that nonpayment of the amortized cost basis is or continues to be zero, even if the U.S. government were to default. Therefore, for those securities, the Corporation does not record expected credit losses. Accrued interest receivable on held to maturity debt securities, which is reported in Accrued interest receivable on the Consolidated Balance Sheet, totaled $37 thousand as of December 31, 2020 and is excluded from the estimate of credit losses. G. Loans Held for Sale Mortgage loans originated and intended for sale in the secondary market are carried at the lower of cost or fair value in the aggregate. Net unrealized temporary losses, if any, are recognized through a valuation allowance by charges to income. H. Portfolio Loans and Leases The Corporation originates construction, Commercial & Industrial, commercial mortgage, residential mortgage, home equity and consumer loans to customers primarily in southeastern Pennsylvania, as well as small-ticket equipment leases to customers nationwide. Although the Corporation has a diversified loan and lease portfolio, its debtors’ ability to honor their contracts is substantially dependent upon the real estate and general economic conditions of the region. Loans and leases that management has the intention and ability to hold for the foreseeable future, or until maturity or pay-off, generally are reported at their outstanding principal balance adjusted for charge-offs, the allowance for credit losses on loans and leases and any deferred fees or costs on originated loans and leases. Interest income is accrued on the unpaid principal balance. Loan and lease origination fees and loan and lease origination costs are deferred and recognized as an adjustment to the related yield using the interest method. The accrual of interest on loans and leases is generally discontinued at the time the loan is 90 days delinquent unless the credit is well secured and in the process of collection. Loans and leases are placed on nonaccrual status or charged-off at an earlier date if collection of principal or interest is considered doubtful. All interest accrued, but not collected for loans that are placed on nonaccrual status or charged-off is charged against interest income. All interest accrued, but not collected, on leases that are placed on nonaccrual status is not charged against interest income until the lease becomes 120 days delinquent, at which point it is charged off. The interest received on these nonaccrual loans and leases is applied to reduce the carrying value of loans and leases. Loans and leases are returned to accrual status when all the principal and interest amounts contractually due are brought current and remain current for at least six months, and future payments are reasonably assured. Once a loan returns to accrual status, any interest payments collected during the nonaccrual period which had been applied to the principal balance are reversed and recognized as interest income over the remaining term of the loan. Purchased loans and leases which have experienced more than insignificant credit deterioration since origination, purchased credit deteriorated (“PCD”) loans and leases, are recorded at the amount paid. An ACL is determined using the same methodology as other portfolio loans and leases. The initial ACL determined on a collective basis is allocated to individual loans. The loan’s purchase price is grossed-up by adding the allocated ACL to arrive at its initial amortized cost basis. The difference between the initial amortized cost basis and the par value of the loan or lease is a noncredit discount or premium, which is amortized into interest income over the life of the loan or lease. Subsequent changes to the ACL associated with PCD loans or leases are recorded through provision expense. I. ACL on Loans and Leases The ACL on loans and leases represents management’s estimate of all expected credit losses over the expected contractual life of our existing portfolio loans and leases. Determining the appropriateness of the ACL on loans and leases is complex and requires judgment by management about the effect of matters that are inherently uncertain. Subsequent evaluations of the then-existing loan portfolio, in light of the factors then prevailing, may result in significant changes in the ACL on loans and leases in those future periods. The provision for credit losses recorded through earnings is the amount necessary to maintain the ACL on loans and leases at the amount of expected credit losses within the loans and leases portfolio. The amount of expense and the corresponding level of ACL on loans and leases are based on management’s evaluation of the collectability of the loan and lease portfolio based on historical loss experience, reasonable and supportable forecasts, and other significant qualitative and quantitative factors not captured in the historical loss experience. The ACL on loans and leases, as reported in our Consolidated Statements of Financial Condition, is adjusted by an expense for credit losses, which is recognized in earnings, and reduced by the charge-off of loan and lease amounts, net of recoveries. For further information on the ACL on loans and leases, see Note 5 - Loans and Leases in the accompanying Notes to Consolidated Financial Statements. Management employs a disciplined process and methodology to establish the ACL on loans and leases that has two basic components: first, a collective (pooled) component for estimated expected credit losses for pools of loans and leases that share similar risk characteristics; and second, an asset-specific component involving individual loans and leases that do not share risk characteristics with other loans and leases and the measurement of expected credit losses for such individual loans. Based upon this methodology, management establishes an asset-specific ACL on loans and leases that do not share risk characteristics with other loans and leases, which generally include nonaccrual loans and leases, TDRs, and PCD loans. The asset-specific ACL is based on the amount of expected credit losses calculated on those loans and leases and amounts determined to be uncollectible are charged off. Factors we consider in measuring the extent of expected credit loss include payment status, collateral value, borrower financial condition, guarantor support and the probability of collecting scheduled principal and interest payments when due. When a loan or lease does not share risk characteristics with other loans or leases, they are individually evaluated for expected credit loss. For loans and leases that are not collateral-dependent, management measures expected credit loss as the difference between the amortized cost basis of the loan and the present value of expected future cash flows discounted at the loan’s effective interest rate. For collateral-dependent loans and leases, expected credit loss is measured as the difference between the amortized cost basis of the loan and the fair value of the underlying collateral. The fair value of the collateral is adjusted for the estimated cost to sell if repayment or satisfaction of a loan is dependent on the sale (rather than only on the operation) of the collateral. If the calculated expected credit loss is determined to be permanent, fixed or nonrecoverable, the credit loss portion of the loan will be charged off against the ACL on loans and leases. Loans and leases designated as having significantly increased credit risk are generally placed on nonaccrual and remain in that status until all principal and interest payments are current and the prospects for future payments in accordance with the loan agreement are reasonably assured, at which point the loan is returned to accrual status. In estimating the component of the ACL on loans and leases that share common risk characteristics, loans and leases are segregated into portfolio segments based on federal call report codes which classify loans and leases based on the primary collateral supporting the loan and lease. Methods utilized by management to estimate expected credit losses include 1) a discounted cash flow (“DCF”) methodology that discounts instrument-level contractual cash flows, adjusted for prepayments and curtailments, incorporating loss expectations, and 2) a weighted average remaining maturity (“WARM”) methodology which contemplates expected losses at a pool-level, utilizing historic loss information. Under both methodologies, management estimates the ACL on loans and leases using relevant available information, from internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts. After the end of the reasonable and supportable forecast period, the loss rates revert to the long-term mean loss rate, or in the case of an input-driven predictive method, the long-term mean of the input, using a reversion period where applicable. Historical credit loss experience, including examination of loss experience at representative peer institutions when the Corporation’s own loss history does not result in estimations that are meaningful to users of the Corporation’s Consolidated Financial Statements, provides the basis for the estimation of expected credit losses. Adjustments to historical loss information are considered for differences in current loan-specific risk characteristics such as differences in underwriting standards, portfolio mix, delinquency level, or term as well as for changes in environmental conditions, such as changes in unemployment rates, property values, or other relevant factors. The DCF methodology uses inputs of current and forecasted macroeconomic indicators to predict future loss rates. The current macroeconomic indicator utilized by the bank is the Pennsylvania unemployment rate. In building the current expected credit loss (“CECL”) model utilized in the DCF methodology, a correlation between this indicator and historic loss levels was developed, enabling a prediction of future loss rates related to future Pennsylvania unemployment rates. The portfolio segments utilizing the DCF methodology as of December 31, 2020 included: CRE - owner-occupied and nonowner-occupied loans, home equity lines of credit, residential mortgages (first and junior liens), construction loans and consumer loans. The WARM methodology uses combined historic loss rates for the Bank and peer institutions, if necessary, gathered from Call Report filings. The selected period for which historic loss rates are used is dependent on management's evaluation of current conditions and expectations of future loss conditions. The portfolio segments utilizing the WARM methodology as of December 31, 2020 included Commercial & Industrial loans and leases. For those loans and leases where the ACL is measured on a collective (pool) basis, management has identified the following portfolio segments based on federal call report codes which classify loans and leases based on the primary collateral supporting the loan or lease: Commercial real estate (“CRE”) loans (owner-occupied and non-owner occupied): The Bank originates mortgage loans for multifamily properties (i.e. buildings which have five or more residential units) and other commercial real estate that is either owner-occupied or managed as an investment property (non-owner occupied) primarily within Pennsylvania, Delaware and Southern and Central New Jersey. Commercial real estate properties primarily include retail buildings/shopping centers, hotels, office/medical buildings and industrial/warehouse space. Multifamily loans are expected to be repaid from the cash flows of the underlying property so the collective amount of rents must be sufficient to cover all operating expenses, property management and maintenance, taxes and debt service. Increases in vacancy rates, interest rates or other changes in general economic conditions can have an impact on the borrower and its ability to repay the loan. Commercial real estate loans are generally considered to have a higher degree of credit risk than multifamily loans as they may be dependent on the ongoing success and operating viability of a fewer number of tenants who are occupying the property and who may have a greater degree of exposure to economic conditions. Home equity lines of credit: The Bank originates the majority of its home equity lines of credit through its retail channel. The primary risk characteristics associated with home equity lines of credit typically involve major living or lifestyle changes to the borrower, including unemployment or other loss of income; unexpected significant expenses, such as major medical expenses, catastrophic events, divorce and death. Home equity lines of credit are typically originated with variable or floating interest rates, which could expose the borrower to higher payments in a rising interest rate environment. Real estate values could decrease and cause the value of the underlying property to fall below the loan amount, creating additional potential loss exposure for the Bank. Residential mortgages secured by first liens: The Bank originates one-to-four family residential mortgage loans primarily within Pennsylvania, Delaware and Southern and Central New Jersey. These loans are secured by first liens on a primary residence or investment property. The risks associated with residential mortgage loans typically involve major living or lifestyle changes to the borrower, including unemployment or other loss of income; unexpected significant expenses, such as major medical expenses, catastrophic events, divorce or death. Residential mortgage loans that have adjustable rates could expose the borrower to higher payments in a rising interest rate environment. Real estate values could decrease and cause the value of the underlying property to fall below the loan amount, creating additional potential loss exposure for the Bank. Residential mortgages secured by junior liens: The Bank originates loans secured by junior liens against one to four family properties primarily within Pennsylvania, Delaware and Southern and Central New Jersey. Loans secured by junior liens are primarily in the form of an amortizing home equity loan. These loans are subordinate to a first mortgage which may be from another lending institution. The risks associated with loans secured by junior liens typically involve major living or lifestyle changes to the borrower, including unemployment or other loss of income, unexpected significant expenses, such as for major medical expenses, catastrophic events, divorce or death. Real estate values could decrease and cause the value of the property to fall below the loan amount, creating additional potential loss exposure for the Bank. Construction: The Bank originates construction loans to finance land development preparatory to erecting new structures or the on-site construction of industrial, commercial, or residential buildings. Construction loans include not only construction of new structures, but also additions or alterations to existing structures and the demolition of existing structures to make way for new structures. Construction loans are generally secured by real estate. The risks are typically specific to the uncertainty on whether the construction will be completed according to the specifications and schedules. Factors that may influence the completion of construction may be customer specific, such as the quality and depth of property management, or related to changes in general economic conditions. Commercial & Industrial: The Bank originates lines of credit and term loans to operating companies for business purposes. The loans are generally secured by business assets such as accounts receivable, inventory, business vehicles and equipment as well as the stock of a company, if privately held. Commercial & Industrial loans are typically repaid first by the cash flows generated by the borrower’s business operations. The risks are typically specific to the underlying business and its ability to generate sustainable profitability and positive cash flow. Factors that may influence a borrower's ability to repay their loan include demand for the business’ products or services, the quality and depth of management, the degree of competition, regulatory changes, and general economic conditions. The ability of the Bank to foreclose and realize sufficient value from business assets securing these loans is often uncertain. To mitigate the risk characteristics of Commercial & Industrial loans, commercial real estate may be included as a secondary source of collateral. The Bank will often require more frequent reporting requirements from the borrower in order to better monitor its business performance. Consumer: The Bank originates or lines of credit to individuals for household, family, and other personal expenditures as well as overdrawn customer deposit balances which are reported as loans. This also represents all other loans that cannot be categorized in any of the previous mentioned loan segments. Consumer loans generally have higher interest rates and shorter terms than residential loans but tend to have higher credit risk due to the type of collateral securing the loan or in some cases the absence of collateral. Leases: The Bank’s wholly-owned subsidiary Bryn Mawr Equipment Financing, Inc. specializes in equipment leases for small- and mid-sized businesses nationally and across a broad range of industries. The Bank’s credit risk generally results from the potential default of borrowers or lessees, which may be driven by customer specific or broader industry related conditions. Accrued interest receivable on loans and leases, which is reported in Accrued interest receivable on the Consolidated Balance Sheet, totaled $12.1 million as of December 31, 2020 and is excluded from the estimate of credit losses due to our charge-off policy to reverse accrued interest in a timely manner on loans and leases that are 90-days past due and deemed nonperforming. However, the Corporation continued to accrue interest on loans and leases for which payment deferrals have been extended to borrowers affected by the COVID-19 pandemic. Deferrals under the Corporation's modification program may be for durations which exceed the Corporation’s 90-day write-off policy for accrued interest. Therefore, these interest deferrals do not qualify for the Corporation’s election to not recognize a credit loss allowance for credit losses on accrued interest receivable. Accordingly, as of December 31, 2020, the Corporation has estimated credit losses for COVID-19 interest deferrals of $64 thousand, which is included as a reduction to Accrued interest receivable on the Consolidated Balance Sheet and Provision for credit losses on the Consolidated Income Statement. Prior to January 1, 2020 As further described in Note 2, “Recent Accounting Pronouncements,” in the accompanying Notes to the Consolidated Financial Statements in this Annual Report on Form 10-K , on January 1, 2020, the Corporation adopted ASU 2016-13 (Topic 326), “Measurement of Credit Losses on Financial Instruments,” which replaces the incurred loss methodology with an expected loss methodology that is referred to as the current expected credit loss (or CECL) methodology. Prior to the adoption of ASC 326 on January 1, 2020, the ACL on loans and leases was maintained at a level that the Corporation believed was sufficient to absorb estimated potential credit losses. Management’s determination of the adequacy of the ACL on loans and leases was based on guidance provided in ASC 450 – Contingencies and ASC 310 - Receivables, and involved the periodic evaluations of the loan and lease portfolio and other relevant factors. However, this evaluation was inherently subjective as it required significant estimates by management. Consideration was given to a variety of factors in establishing these estimates. Quantitative factors in the form of historical net charge-off rates by portfolio segment were considered. In connection with these quantitative factors, management established what it deems to be an adequate look-back period (“LBP”) for the charge-off history. As of December 31, 2019, management utilized a five-year LBP, which it believes adequately captures the trends in charge-offs. In addition, management developed an estimate of a loss emergence period (“LEP”) for each segment of the loan portfolio based on analyses of actual charge-offs tracked back in time to the triggering event for the eventual loss. The LEP estimates the time between the occurrence of a loss event for a borrower and an actual charge-off of a loan. In addition, various qualitative factors were considered, including the specific terms and conditions of loans, changes in underwriting standards, delinquency statistics, industry concentrations and overall exposure of a single customer. In addition, consideration was given to the adequacy of collateral, the dependence on collateral, and the results of internal loan reviews, including a borrower’s financial strengths, their expected cash flows, and their access to additional funds. As part of the process of calculating the ACL on loans and leases for the different segments of the loan and lease portfolio, management considered certain credit quality indicators, including risk grades assigned to each loan and the performance/non-performance status of a loan. Prior to January 1, 2020, a loan or lease was considered impaired when, based on current information, it was probable that management would be unable to collect the contractually scheduled payments of principal or interest. When assessing impairment, management considered various factors, which included payment status, realizable value of collateral and the probability of collecting scheduled principal and interest payments when due. Loans and leases that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determined the significance of payment delays and payment shortfalls on a case-by-case

Accounting Policies [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements The following FASB Accounting Standards Updates (“ASUs”) are divided into pronouncements which have been adopted by the Corporation during the year ended December 31, 2020, and those which are not yet effective as of December 31, 2020 and have been evaluated or are currently being evaluated by management. Adopted Pronouncements in 2020: FASB ASU 2016-13 (Topic 326), “Measurement of Credit Losses on Financial Instruments” On January 1, 2020, the Corporation adopted ASU 2016-13 (Topic 326), “Measurement of Credit Losses on Financial Instruments,” which replaces the incurred loss methodology with an expected loss methodology that is referred to as the current expected credit loss (or CECL) methodology. This standard eliminates the Provision for Loan and Lease Losses and Allowance for Loan and Lease Losses line items and establishes the Provision for Credit Losses (“PCL”) and ACL line items. The measurement of expected credit losses under the CECL methodology is applicable to financial assets measured at amortized cost, including loan receivables and held-to-maturity debt securities. It also applies to OBS credit exposures not accounted for as insurance (loan commitments, standby letters of credit, financial guarantees, and other similar instruments) and net investments in leases recognized by a lessor in accordance with Topic 842 on leases. In addition, ASC 326 made changes to the accounting for available for sale debt securities. One such change is to require credit losses to be presented as an allowance rather than as a write-down on available-for-sale debt securities management does not intend to sell or believes that it is more likely than not they will be required to sell. The Corporation adopted ASC 326 using the modified retrospective approach method for all financial assets measured at amortized cost and OBS credit exposures. Results for reporting periods beginning after January 1, 2020 are presented under ASC 326 while prior period amounts continue to be reported in accordance with previously applicable GAAP. In conjunction with the adoption of CECL, the Corporation has revised its segmentation to align with the methodology applied in determining the ACL for loans and leases under CECL, which is based on federal call report codes which classify loans based on the primary collateral supporting the loan. Segmentation prior to the adoption of CECL was based on product type or purpose. As such, certain reclassifications were made to conform prior-period amounts to current period presentation. Upon adoption, the Corporation's total ACL increased by $4.0 million, or 17.5%, which included an increase in ACL on loans and leases of $3.2 million and an increase in the reserve for OBS exposures, which is included within Other Liabilities on the Consolidated Balance Sheet, of $821 thousand. The increase in the total ACL resulted in a $2.8 million decrease to retained earnings, net of deferred taxes. The overall change in total ACL upon adoption was primarily due to the move to a life of loan reserve estimate as well as methodology changes required under CECL. The Corporation adopted CECL using the prospective transition approach for financial assets purchased with credit deterioration (“PCD”) that were previously classified as purchased credit impaired (“PCI”) and accounted for under ASC 310-30. In accordance with the standard, management did not reassess whether PCI assets met the criteria of PCD assets as of the date of adoption. On January 1, 2020, the amortized cost basis of the PCD assets were adjusted to reflect the addition of $481 thousand of the allowance for credit losses. The remaining noncredit discount (based on the adjusted amortized cost basis) will be accreted into interest income at the effective interest rate as of January 1, 2020.

Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. ASU 2017-04 became effective for the Corporation on January 1, 2020, and will follow such guidance in connection with our next annual impairment testing, or prior to that if any such change constitutes a triggering event outside of the quarter from when the annual goodwill impairment test is performed. Management does not expect the adoption of this ASU to have a material impact on our Consolidated Financial Statements and related disclosures. FASB ASU 2018-13, “Fair Value Measurement Disclosure Framework” Issued in August 2018, ASU 2018-13 modifies, adds and removes certain disclosures aimed to improve the overall usefulness of the disclosure requirements for fair value measurements. The guidance became effective for the Corporation on January 1, 2020 and the adoption of this ASU did not have a material impact on our Consolidated Financial Statements and related disclosures. Pronouncements Not Effective as of December 31, 2020: FASB ASU 2018-14 (Topic 715), "Compensation-Retirement Benefits - Defined Benefit Plans-General" Issued in August 2018, the ASU 2018-14, modifies, adds and removes certain disclosures aimed to improve the overall usefulness of the disclosure requirements to financial statement users. The guidance is effective for annual periods beginning after December 15, 2020. Early adoption is permitted. Use of the retrospective method is required. Management does not expect the adoption of this ASU to have a material impact on our Consolidated Financial Statements and related disclosures. FASB ASU 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes” Issued in December 2019, ASU 2019-12 adds new guidance to simplify accounting for income taxes, changes the accounting for certain income tax transactions and makes minor improvements to the codification. The guidance is effective for annual periods beginning after December 15, 2020. Early adoption is permitted. Management does not expect the adoption of this ASU to have a material impact on our Consolidated Financial Statements and related disclosures. FASB ASU No. 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting” Issued in March 2020, ASU No. 2020-04 provides optional guidance to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. Specifically, the guidance permits an entity, when certain criteria are met, to consider amendments to contracts made to comply with reference rate reform to meet the definition of a modification under GAAP. It further allows hedge accounting to be maintained and a one-time transfer or sale of qualifying held-to-maturity securities. The expedients and exceptions provided by the amendments are permitted to be adopted any time through December 31, 2022 and do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for certain optional expedients elected for certain hedging relationships existing as of December 31, 2022. The Corporation will apply the guidance to any contracts modifications made due to reference rate reform.

Business Combinations	Business Combinations Domenick & Associates (“Domenick”) The Bank’s subsidiary, BMT Insurance Advisors, Inc., completed the acquisition of Domenick, a full-service insurance agency established in 1993 and headquartered in the Old City section of Philadelphia, on May 1, 2018. The consideration paid was $1.5 million, of which $750 thousand was paid at closing, $225 thousand was paid during the third quarter of 2019, $175 thousand was paid during the second quarter of 2020 and one contingent cash payment, not to exceed $250 thousand, will be payable in 2021, subject to the attainment of certain targets during the year. The following table details the consideration paid, the initial estimated fair value of identifiable assets acquired and liabilities assumed as of the date of acquisition and the resulting goodwill recorded: (dollars in thousands) Consideration paid: Cash paid at closing $ 750 Contingent payment liability (present value) 706 Value of consideration $ 1,456 Assets acquired: Cash and due from banks 370 Intangible assets - customer relationships 779 Premises and equipment 1 Other assets 316 Total assets 1,466 Liabilities assumed: Accounts payable 657 Other liabilities 30 Total liabilities $ 687 Net assets acquired $ 779 Goodwill resulting from acquisition of Domenick $ 677 As of June 30, 2018, the estimates of the fair value of identifiable assets acquired and liabilities assumed in the Domenick acquisition were final. Royal Bancshares of Pennsylvania, Inc. On December 15, 2017, the previously announced merger of Royal Bancshares of Pennsylvania, Inc. (“RBPI”) with and into BMBC (the “Effective Date”), and the merger of Royal Bank America with and into the Bank (collectively, the "RBPI Merger"), pursuant to the Agreement and Plan of Merger, by and between RBPI and BMBC, dated as of January 30, 2017 (the “Agreement”) was completed. In accordance with the Agreement, the aggregate share consideration paid to RBPI shareholders consisted of 3,101,316 shares of BMBC's common stock. Shareholders of RBPI received 0.1025 shares of BMBC's common stock for each share of RBPI Class A common stock and 0.1179 shares of BMBC's common stock for each share of RBPI Class B common stock owned as of the Effective Date of the RBPI Merger, with cash-in-lieu of fractional shares totaling $7 thousand. Holders of in-the-money options to purchase RBPI Class A common stock received cash totaling $112 thousand. In addition, 1,368,040 warrants to purchase Class A common stock of RBPI, valued at $1.9 million were converted to 140,224 warrants to purchase BMBC's common stock. In accordance with the acquisition method of accounting, assets acquired and liabilities assumed were preliminarily adjusted to their fair values as of the Effective Date. The excess of consideration paid above the fair value of net assets acquired was recorded as goodwill. This goodwill is not amortizable nor is it deductible for income tax purposes. In connection with the RBPI Merger, the consideration paid and the estimated fair value of identifiable assets acquired and liabilities assumed as of the Effective Date, which include the effects of any measurement period adjustments in accordance with ASC 805-10, are summarized in the following table: (dollars in thousands) Consideration paid: Common shares issued (3,101,316) $ 136,768 Cash in lieu of fractional shares 7 Cash-out of certain options 112 Fair value of warrants assumed 1,853 Value of consideration $ 138,740 Assets acquired: Cash and due from banks 17,092 Investment securities available for sale 121,587 Loans 566,228 Premises and equipment 8,264 Deferred income taxes 34,823 Bank-owned life insurance 16,550 Core deposit intangible 4,670 Favorable lease asset 566 Other assets 13,611 Total assets $ 783,391 Liabilities assumed: Deposits 593,172 FHLB and other long-term borrowings 59,568 Short-term borrowings 15,000 Junior subordinated debentures 21,416 Unfavorable lease liability 322 Other liabilities 31,381 Total liabilities $ 720,859 Net assets acquired $ 62,532 Goodwill resulting from acquisition of RBPI $ 76,208 As of December 31, 2018, the estimates of the fair value of identifiable assets acquired and liabilities assumed in the RBPI Merger were final. Due Diligence, Merger-Related and Merger Integration Expenses Due diligence, merger-related and merger integration expenses include consultant costs, investment banker fees, contract breakage fees, retention bonuses for severed employees, salary and wages for redundant staffing involved in the integration of the institutions and bonus accruals for members of the merger integration team.

As of December 31, 2020, management had not made a decision to sell any of the Corporation’s available for sale investment securities in an unrealized loss position, nor did management consider it more likely than not that it would be required to sell such securities before recovery of their amortized cost basis. Management has evaluated available for sale debt securities that are in an unrealized loss position and has determined that the decline in value is unrelated to credit loss and is related to the change in market interest rates since purchase. Factors considered in this evaluation included the extent to which fair value is less than amortized cost, any explicit or implicit guarantees by the U.S. government, any changes to the rating of the security by the rating agency, and adverse conditions specifically related to the security, among other factors. As of December 31, 2020, approximately 90.8% of the Corporation’s available for sale investment securities were U.S. Treasuries or mortgage-backed securities or collateral mortgage obligations which were issued or guaranteed by U.S. government-sponsored entities and agencies. In addition, none of the available for sale debt securities held by the Corporation are past due as of December 31, 2020. As of December 31, 2020 and December 31, 2019, there were no holdings of securities of any one issuer, other than the U.S. government and its agencies, in an amount greater than 10% of shareholders’ equity. As of December 31, 2020 and December 31, 2019, securities having a fair value of $282.3 million and $156.4 million, respectively, were specifically pledged as collateral for public funds, trust deposits, the FRB discount window program, FHLB borrowings, collateral requirements in derivative contracts, and other purposes. Advances by the FHLB are collateralized by a blanket lien on non-pledged, mortgage-related loans and securities as part of the Corporation’s borrowing agreement with the FHLB as well as certain securities individually pledged by the Corporation. The amortized cost and fair value of available for sale investment and mortgage-related securities available for sale as of December 31, 2020 and December 31, 2019, by contractual maturity, are shown below. Expected maturities will differ from contractual maturities as borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.

As of December 31, 2020 and December 31, 2019, the Corporation’s investment securities held in trading accounts totaled $8.6 million and $8.6 million, respectively, and primarily consist of deferred compensation trust accounts which are invested in listed mutual funds whose diversification is at the discretion of the deferred compensation plan participants and rabbi trust accounts established to fund certain unqualified pension obligations. Investment securities held in trading accounts are reported at fair value, with adjustments in fair value reported through income. Changes in the fair value of investments held in the deferred compensation trust accounts create corresponding changes in the liability to the deferred compensation plan participants.

Loans and Leases	Loans and Leases The loan and lease portfolio consists of loans and leases originated by the Corporation, as well as loans acquired in prior acquisitions. Certain tables in this footnote are presented with a breakdown between originated and acquired loans and leases. As further described in Note 2, “Recent Accounting Pronouncements,” in the accompanying Notes to the Consolidated Financial Statements in this Annual Report on Form 10-K, the Corporation adopted ASC 326 using the modified retrospective approach method for all financial assets measured at amortized cost and OBS credit exposures. Results for reporting periods beginning after January 1, 2020 are presented under ASC 326 while prior period amounts continue to be reported in accordance with previously applicable GAAP. In conjunction with the adoption of CECL, the Corporation has revised its segmentation to align with the methodology applied in determining the ACL for loans and leases under CECL, which is based on federal call report codes which classify loans based on the primary collateral supporting the loan. Segmentation prior to the adoption of CECL was based on product type or purpose. As such, certain reclassifications were made to conform prior-period amounts to current period presentation. A.

Allowance for Credit Losses (“ACL”) on Loans and Leases As further described in Note 2, “Recent Accounting Pronouncements,” in the accompanying Notes to the Consolidated Financial Statements in this Annual Report on Form 10-K, the Corporation adopted ASU 2016-13 (Topic 326 - Credit Losses) on January 1, 2020, which changed the way we estimate credit losses for loans and leases beginning after January 1, 2020. The ACL on loans and leases represents management’s estimate of all expected credit losses over the expected contractual life of our existing portfolio loans and leases. Determining the appropriateness of the ACL on loans and leases is complex and requires judgment by management about the effect of matters that are inherently uncertain. Subsequent evaluations of the then-existing loan portfolio, in light of the factors then prevailing, may result in significant changes in the ACL on loans and leases in those future periods. The provision for credit loss recorded through earnings is the amount necessary to maintain the ACL on loans and leases at the amount of expected credit losses within the loans and leases portfolio. The amount of expense and the corresponding level of ACL on loans and leases are based on management’s evaluation of the collectability of the loan and lease portfolio based on historical loss experience, reasonable and supportable forecasts, and other significant qualitative and quantitative factors. The ACL on loans and leases, as reported in our Consolidated Statements of Financial Condition, is adjusted by an expense for credit losses, which is recognized in earnings, and reduced by the charge-off of loan and lease amounts, net of recoveries. Management employs a disciplined process and methodology to establish the ACL on loans and leases that has two basic components: first, a collective (pooled) component for estimated expected credit losses for pools of loans and leases that share similar risk characteristics; and second, an asset-specific component involving individual loans and leases that do not share risk characteristics with other loans and leases and the measurement of expected credit losses for such individual loans. Based upon this methodology, management establishes an asset-specific ACL on loans and leases that do not share risk characteristics with other loans and leases, which generally include nonaccrual loans and leases, TDRs, and PCD loans. The asset-specific ACL is based on the amount of expected credit losses calculated on those loans and leases and amounts determined to be uncollectible are charged off. Factors we consider in measuring the extent of expected credit loss include payment status, collateral value, borrower financial condition, guarantor support and the probability of collecting scheduled principal and interest payments when due. When a loan or lease does not share risk characteristics with other loans or leases, they are individually evaluated for expected credit loss. For loans and leases that are not collateral-dependent, management measures expected credit loss as the difference between the amortized cost basis in the loan and the present value of expected future cash flows discounted at the loan’s effective interest rate. For collateral-dependent loans, expected credit loss is measured as the difference between the amortized cost basis in the loan and the fair value of the underlying collateral. The fair value of the collateral is adjusted for the estimated cost to sell if repayment or satisfaction of a loan is dependent on the sale (rather than only on the operation) of the collateral. If the calculated expected credit loss is determined to be permanent, fixed or nonrecoverable, the credit loss portion of the loan will be charged off against the ACL on loans and leases. Loans and leases designated as having significantly increased credit risk are generally placed on nonaccrual and remain in that status until all principal and interest payments are current and the prospects for future payments in accordance with the loan agreement are reasonably assured, at which point the loan is returned to accrual status. In estimating the component of the ACL on loans and leases that share common risk characteristics, loans and leases are segregated into portfolio segments based on federal call report codes which classify loans and leases based on the primary collateral supporting the loan and lease. Methods utilized by management to estimate expected credit losses include 1) a DCF methodology that discounts instrument-level contractual cash flows, adjusted for prepayments and curtailments, incorporating loss expectations, and 2) a WARM methodology which contemplates expected losses at a pool-level, utilizing historic loss information. Under both methodologies, management estimates the ACL on loans and leases using relevant available information, from internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts. After the end of the reasonable and supportable forecast period, the loss rates revert to the long-term mean loss rate, or in the case of an input-driven predictive method, the long-term mean of the input, using a reversion period where applicable. Historical credit loss experience, including examination of loss experience at representative peer institutions when the Corporation’s own loss history does not result in estimations that are meaningful to users of the Corporation’s Consolidated Financial Statements, provides the basis for the estimation of expected credit losses. Adjustments to historical loss information are considered for differences in current loan-specific risk characteristics such as differences in underwriting standards, portfolio mix, delinquency level, or term as well as for changes in environmental conditions, such as changes in unemployment rates, property values, or other relevant factors. The DCF methodology uses inputs of current and forecasted macroeconomic indicators to predict future loss rates. The current macroeconomic indicator utilized by the bank is the Pennsylvania unemployment rate. In building the CECL model utilized in the DCF methodology, a correlation between this indicator and historic loss levels was developed, enabling a prediction of future loss rates related to projections of future Pennsylvania unemployment rates. The portfolio segments utilizing the DCF methodology as of December 31, 2020 included: CRE - owner-occupied and nonowner-occupied loans, home equity lines of credit, residential mortgages (first and junior liens), construction loans and consumer loans. The WARM methodology uses combined historic loss rates for the Bank and peer institutions, if necessary, gathered from Call Report filings. The selected period for which historic loss rates are used is dependent on management's evaluation of current conditions and expectations of future loss conditions. The portfolio segments utilizing the WARM methodology as of December 31, 2020 included Commercial & Industrial loans and leases. As of December 31, 2020, management's current and forecasted economic outlook, which is central to the calculation of the ACL, improved since the first quarter of 2020, when the impact of COVID-19 was initially incorporated into management's current and forecasted economic outlook. Pennsylvania unemployment, which is used as the primary driver for forecasting future loss rates, has continued to improve during 2020 and is projected to continue on that path for the next four quarters. Following this 4-quarter forecast, the Pennsylvania unemployment rate will revert, immediately, to its long-term average. In addition to these assumptions, management applied additional qualitative factors related to the negative impact of the pandemic on certain segments of the portfolio. These segments included the retail and hospitality sub-segments of the non-owner-occupied CRE segment. The hospitality sub-segment was particularly hard-hit by the sharp drop in travel for both business and leisure, while the retail sub-segment suffered a significant loss of revenue due to lockdowns as well as shoppers' behavioral changes which favored online shopping as opposed to traditional brick-and-mortar purchases. These factors suggested a heightened probability of default for this type of borrower and was incorporated into the CECL model.

Periodic reviews of loans are conducted by both in-house staff as well as external loan reviewers. The result of these reviews is reflected in the risk grade assigned to each loan. These internally assigned grades are as follows: • Pass – Loans considered satisfactory with no indications of deterioration. • Pass-Watch – Loans that are performing, but which may have a potential deficiency which the borrower appears to be managing or a possible deficiency in the future. • Special mention – Loans classified as special mention have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the institution’s credit position at some future date. • Substandard – Loans classified as substandard are inadequately protected by the current net worth and payment capacity of the obligor or of the collateral pledged, if any. Substandard loans have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected. • Doubtful – Loans classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable.

As discussed in Section I, "ACL on Loans and Leases," of Note 1, "Summary of Significant Accounting Policies," management currently utilizes the Pennsylvania unemployment rate as a macroeconomic indicator to predict future loss rates based on historic correlations between movements in this rate and observed loss experience. Historically, the Corporation has had relatively nominal levels of adversely-rated loans. As such, a meaningful correlation between these adversely-rated loans and Pennsylvania unemployment rates is not available. As of December 31, 2020, management considered the recent downgrades in the risk ratings of certain subsegments of the CRE - nonowner-occupied loans, in particular, retail and hospitality, and applied a qualitative adjustment to estimate a larger ACL for these loan types. The following tables detail the carrying value of all portfolio loans and leases by portfolio segment based on the credit quality indicators used to determine the ACL on loans as leases under the incurred loss methodology as of December 31, 2019: Credit Risk Profile by Internally Assigned Grade As of December 31, 2019 (dollars in thousands) Pass Special Mention Substandard Doubtful Total CRE - nonowner-occupied $ 1,293,230 $ 12,463 $ 31,474 $ — $ 1,337,167 CRE - owner-occupied 515,921 2,056 9,630 — 527,607 Home equity lines of credit 222,405 829 1,028 — 224,262 Residential mortgage - 1st liens 702,843 1,039 2,808 — 706,690 Residential mortgage - junior liens 36,760 — 83 — 36,843 Construction 196,231 — 5,967 — 202,198 Commercial & Industrial 418,636 3,535 10,056 — 432,227 Consumer 52,270 — 4,971 — 57,241 Leases 164,195 — 883 — 165,078 Total $ 3,602,491 $ 19,922 $ 66,900 $ — $ 3,689,313 The following tables present the amortized cost basis of loans and leases on nonaccrual status and loans and leases past due over 89 days still accruing December 31, 2020, in accordance with ASC 326: As of December 31, 2020 (dollars in thousands) Nonaccrual with No ACL Nonaccrual with ACL Loans Past Due Over 89 Days Still Accruing CRE - nonowner-occupied $ 57 $ — $ — CRE - owner-occupied 1,659 — — Home equity lines of credit 729 — — Residential mortgage - 1st liens 99 — — Residential mortgage - junior liens 85 — — Construction — — — Commercial & Industrial 1,775 — — Consumer — 30 — Leases — 872 — Total non-performing loans and leases $ 4,404 $ 902 $ — For the year ended December 31, 2020, $122 thousand of interest income was recognized on nonaccrual loans and leases. Collateral-dependent loans and leases for which the borrower is experiencing financial difficulty and repayment is expected to be provided substantially through the sale of the collateral are, in general, individually evaluated for credit losses. Identified shortfalls between the amortized cost of the individually evaluated loan or lease and the value, less selling costs, of the underlying collateral are charged against the ACL. In certain cases, when the loan or lease is serviced by a third-party, and management is unable to process a timely charge-down of the loan or lease, it will assess a specific ACL to the individual loan or lease. This ACL represents the shortfall between the amortized cost and realizable value of the collateral. The following tables present the amortized cost basis of collateral-dependent loans and leases, indicating the type of collateral and the ACL determined through individual evaluation for credit loss under the CECL methodology, as of December 31, 2020: As of December 31, 2020 (dollars in thousands) Real Estate Collateral Non-Real Estate Collateral Individually Evaluated ACL CRE - nonowner-occupied $ 57 $ — $ — CRE - owner-occupied 1,659 — — Home equity lines of credit 729 — — Residential mortgage - 1st liens 99 — — Residential mortgage - junior liens 85 — — Construction — — — Commercial & Industrial — 1,775 — Consumer — 30 30 Leases — 872 814 Total collateral-dependent loans and leases $ 2,629 $ 2,677 $ 844 The following table provides an analysis of the Corporation’s impaired loans as of December 31, 2019 under the incurred loss methodology: As of December 31, 2019 Recorded Investment (2) Principal Related Average (dollars in thousands) Impaired loans with related ACL: Residential mortgage - 1st liens $ 1,387 $ 1,387 $ 190 $ 1,402 Residential mortgage - junior liens 1,765 1,765 206 1,772 Consumer 43 43 22 44 Total $ 3,195 $ 3,195 $ 418 $ 3,218 Impaired loans without related ACL (1) : CRE - nonowner-occupied $ 383 $ 383 $ — $ 393 CRE - owner-occupied 4,159 5,127 — 5,218 Home equity lines of credit 636 636 — 645 Residential mortgage - 1st liens 3,325 3,610 — 3,647 Residential mortgage - junior liens 554 555 — 553 Commercial & Industrial 2,335 2,493 — 2,457 Consumer 42 57 — 45 Total $ 11,434 $ 12,861 $ — $ 12,958 Grand total $ 14,629 $ 16,056 $ 418 $ 16,176 (1) The table above does not include the recorded investment of $1.1 million of impaired leases with a $64 thousand related ACL on loans and leases. (2) Recorded investment equals principal balance, net of deferred origination costs/fees and loan marks, less partial charge-offs and interest payments on non-performing loans that have been applied to principal. For the year ended December 31, 2019, $440 thousand of interest income was recognized on impaired loans and leases. F. Troubled Debt Restructurings (“TDRs”) The restructuring of a loan is considered a “troubled debt restructuring” if both of the following conditions are met: (i) the borrower is experiencing financial difficulties, and (ii) the creditor has granted a concession. The most common concessions granted include one or more modifications to the terms of the debt, such as (a) a reduction in the interest rate for the remaining life of the debt, (b) an extension of the maturity date at an interest rate lower than the current market rate for new debt with similar risk, (c) a temporary period of interest-only payments, (d) a reduction in the contractual payment amount for either a short period or remaining term of the loan, and (e) for leases, a reduced lease payment. A less common concession granted is the forgiveness of a portion of the principal. The determination of whether a borrower is experiencing financial difficulties takes into account not only the current financial condition of the borrower, but also the potential financial condition of the borrower, were a concession not granted. Similarly, the determination of whether a concession has been granted is very subjective in nature. For example, simply extending the term of a loan at its original interest rate or even at a higher interest rate could be interpreted as a concession unless the bo

During the fourth quarter of 2020, the Corporation recognized a $2.3 million gain on sale of long-lived assets in connection with the sale of an owned office space building and its land. During the fourth quarter of 2020, the Corporation recognized $801 thousand of disposal expense of leasehold improvements and equipment primarily associated with the early termination of leased office space. The disposal expense was recorded within Occupancy and bank premises expenses on the Consolidated Statement of Income. The Corporation performs impairment assessments for long-lived assets when events or changes in circumstances indicate that their carrying values may not be recoverable. During the fourth quarter of 2020, the Corporation recognized $150 thousand of impairment losses of leasehold improvements related to a planned branch closure. The recognized loss was recorded within Impairment of long-lived-assets on the Consolidated Statement of Income.

At December 31, 2020 and 2019, the fair value of the MSRs was $2.6 million and $4.8 million, respectively. The fair value of the MSRs for these dates was determined using values obtained from a third party which utilizes a valuation model which calculates the present value of estimated future servicing income. The model incorporates assumptions that market participants use in estimating future net servicing income, including estimates of prepayment speeds and discount rates. Mortgage loan prepayment speed is the annual rate at which borrowers are forecasted to repay their mortgage loan principal and is based on historical experience. The discount rate is used to determine the present value of future net servicing income. Another key assumption in the model is the required rate of return the market would expect for an asset with similar risk. These assumptions can, and generally will, change quarterly valuations as market conditions and interest rates change. Management reviews, annually, the process utilized by its independent third-party valuation experts. These assumptions and sensitivities are hypothetical and should be used with caution. As the figures indicate, changes in fair value based on a 10% variation in assumptions generally cannot be extrapolated because the relationship of the change in assumptions to the change in fair value may not be linear. Also, the effect of a variation in a particular assumption on the fair value of the MSRs is calculated without changing any other assumption. In reality, changes in one factor may result in changes in another, which could magnify or counteract the sensitivities.

Management determined that no impairment of goodwill or indefinite-lived intangible assets was identified as a result of the annual impairment analyses. Future impairment testing will be conducted each October 31, unless a triggering event occurs in the interim that would suggest possible impairment, in which case it would be tested as of the date of the triggering event. For the two months ended December 31, 2020, management determined there were no events that would necessitate impairment testing of goodwill or indefinite-lived intangible assets. Amortization expense on finite-lived intangible assets was $3.6 million, $3.8 million, and $3.7 million for the years ended December 31, 2020, 2019, and 2018, respectively.

C. Other Borrowings Information In connection with its FHLB borrowings, the Corporation is required to hold the capital stock of the FHLB. The amount of capital stock held was $12.7 million at July 12, 1905, and $23.7 million at July 11, 1905. The carrying amount of the FHLB stock approximates its redemption value. The level of required investment in FHLB stock is based on the balance of outstanding loans the Corporation has from the FHLB. Although FHLB stock is a financial instrument that represents an equity interest in the FHLB, it does not have a readily determinable fair value. FHLB stock is generally viewed as a long-term investment. Accordingly, when evaluating FHLB stock for impairment, its value should be determined based on the ultimate recoverability of the par value rather than by recognizing temporary declines in value. The Corporation had a maximum borrowing capacity with the FHLB of $1.77 billion as of July 12, 1905 of which the unused capacity was $1.70 billion. In addition, there were $74.0 million in the overnight federal funds line available and $127.7 million of Federal Reserve Discount Window capacity.

Subordinated Notes	Subordinated Notes On December 13, 2017, BMBC completed the issuance of $70.0 million in aggregate principal amount of fixed-to-floating rate subordinated notes due 2027 (the "2027 Notes") in an underwritten public offering. On August 6, 2015, BMBC completed the issuance of $30.0 million in aggregate principal amount of fixed-to-floating rate subordinated notes due 2025 (the "2025 Notes") in a private placement transaction to institutional accredited investors. The subordinated notes qualify as Tier 2 capital for regulatory capital purposes, subject to applicable limitations. The following tables detail the subordinated notes, including debt issuance costs, as of December 31, 2020 and 2019: December 31, 2020 December 31, 2019 (dollars in thousands) Balance Rate (1)(2) Balance Rate (1)(2) Subordinated notes – due 2027 $ 69,133 4.25 % $ 69,009 4.25 % Subordinated notes – due 2025 29,750 3.29 % 29,696 4.75 % Total subordinated notes $ 98,883 $ 98,705 (1) The 2027 Notes bear interest at an annual fixed rate of 4.25% from the date of issuance until and including December 14, 2022, and will thereafter bear interest at a variable rate that will reset quarterly to a level equal to the then-current three-month LIBOR rate plus 2.050% until December 15, 2027, or any early redemption date. (2) The 2025 Notes were bearing interest at an annual fixed rate of 4.75% from the date of issuance until and including August 14, 2020, and thereafter bear interest at a variable rate that will reset quarterly to a level equal to the then-current three-month LIBOR rate plus 3.068% until August 15, 2025, or any early redemption date.

Junior Subordinated Debenture Owed to Unconsolidated Subsidiary Trust [Abstract]
Junior Subordinated Debentures	Junior Subordinated Debentures In connection with the RBPI Merger, the Corporation acquired Royal Bancshares Capital Trust I (“Trust I”) and Royal Bancshares Capital Trust II (“Trust II”) (collectively, the “Trusts”), which were utilized for the sole purpose of issuing and selling capital securities representing preferred beneficial interests. Although BMBC owns $774 thousand of the common securities of Trust I and Trust II, the Trusts are not consolidated into the Corporation’s consolidated financial statements as the Corporation is not deemed to be the primary beneficiary of these entities. In connection with the issuance and sale of the capital securities, RBPI issued, and BMBC assumed as a result of the RBPI Merger, junior subordinated debentures to the Trusts of $10.7 million each, totaling $21.4 million. The junior subordinated debentures incur interest at a coupon rate of 2.37% as of December 31, 2020. The rate resets quarterly based on 3-month LIBOR plus 2.15%. Each of Trust I and Trust II issued an aggregate principal amount of $12.5 million of capital securities initially bearing fixed and/or fixed/floating interest rates corresponding to the debt securities held by each trust to an unaffiliated investment vehicle and an aggregate principal amount of $387 thousand of common securities bearing fixed and/or fixed/floating interest rates corresponding to the debt securities held by each trust to BMBC. As a result of the RBPI Merger, BMBC has fully and unconditionally guaranteed all of the obligations of the Trusts, including any distributions and payments on liquidation or redemption of the capital securities. The rights of holders of common securities of the Trusts are subordinate to the rights of the holders of capital securities only in the event of a default; otherwise, the common securities’ economic and voting rights are pari passu with the capital securities. The capital and common securities of the Trusts are subject to mandatory redemption upon the maturity or call of the junior subordinated debentures held by each. Unless earlier dissolved, the Trusts will dissolve on December 15, 2034. The junior subordinated debentures are the sole assets of Trusts, mature on December 15, 2034, and may be called at par by BMBC any time. The Corporation records its investments in the Trusts’ common securities of $387 thousand each as investments in unconsolidated entities and records dividend income upon declaration by Trust I and Trust II.

Leases [Abstract]
Operating Leases	Operating Leases The Corporation’s operating leases consist of various retail branch locations and corporate offices. As of December 31, 2020, the Corporation’s leases have remaining lease terms ranging from three months to twenty-one years, three months, including extension options that the Corporation is reasonably certain will be exercised. The Corporation’s leases include fixed rental payments, and certain of our leases also include variable rental payments where lease payments may increase at pre-determined dates based on the change in the consumer price index. The Corporation’s lease agreements include gross leases as well as leases in which we make separate payments to the lessor for items such as the property taxes assessed on the property or a portion of the common area maintenance associated with the property. We have elected the practical expedient not to separate lease and non-lease components for all of our building leases. The Corporation also elected to not recognize ROU assets and lease liabilities for short-term leases, which consist of certain leases of the Corporation’s limited-hour retirement community offices. The following table details the Corporation’s ROU assets and related lease liabilities as of December 31, 2020 and 2019: As of December 31, (dollars in thousands) 2020 2019 Operating lease right-of-use assets $ 34,601 $ 40,961 Operating lease liabilities 40,284 45,258 The components of lease expense were as follows: Year Ended December 31, (dollars in thousands) 2020 2019 Operating lease expense $ 4,773 $ 5,295 Short term lease expense 59 59 Variable lease expense 1,295 1,795 Sublease income (36) (32) Total lease expense $ 6,091 $ 7,117 The Corporation performs impairment assessments for ROU assets when events or changes in circumstances indicate that their carrying values may not be recoverable. In addition to the lease costs disclosed in the table above, during the fourth quarter of 2020, the Corporation recognized a $1.5 million impairment loss for an ROU asset related to a planned branch closure. The recognized loss was recorded within Impairment of long-lived-assets on the Consolidated Statement of Income. Supplemental cash flow information related to leases was as follows: Year Ended December 31, (dollars in thousands) 2020 2019 Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows from operating leases $ 4,705 $ 5,174 ROU assets obtained in exchange for lease liabilities — 44,609 Reductions to ROU assets resulting from reductions to lease obligations (1,818) — Maturities of operating lease liabilities under FASB ASC 842 “Leases” as of December 31, 2020 are as follows: (dollars in thousands) December 31, 2020 2021 $ 4,176 2022 3,924 2023 3,771 2024 3,793 2025 3,859 2026 and thereafter 32,548 Total lease payments 52,071 Less: imputed interest 11,787 Present value of operating lease liabilities $ 40,284 As of December 31, 2020, the weighted-average remaining lease term, including extension options that the Corporation is reasonably certain will be exercised, for all operating leases is 13.93 years. Because we generally do not have access to the rate implicit in the lease, we utilize our incremental borrowing rate as the discount rate. The weighted average discount rate associated with operating leases as of December 31, 2020 is 3.59%. As of December 31, 2020, the Corporation had not entered into any material leases that have not yet commenced.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives and Hedging Activities	Derivatives and Hedging Activities Derivative financial instruments involve, to varying degrees, interest rate, market and credit risk. Management manages these risks as part of its asset and liability management process and through credit policies and procedures. Management seeks to minimize counterparty credit risk by establishing credit limits and collateral agreements and utilizes certain derivative financial instruments to enhance its ability to manage interest rate risk that exists as part of its ongoing business operations. The derivative transactions entered into by the Corporation are an economic hedge of a derivative offerings to Bank customers. The Corporation does not use derivative financial instruments for trading purposes. Customer Derivatives – Interest Rate Swaps . The Corporation enters into interest rate swaps with commercial loan customers and correspondent banks wishing to manage interest rate risk. The Corporation then enters into corresponding swap agreements with swap dealer counterparties to economically hedge the exposure arising from these contracts. The interest rate swaps with both the customers and third parties are not designated as hedges under FASB ASC 815 and are marked to market through earnings. As the interest rate swaps are structured to offset each other, changes to the underlying benchmark interest rates considered in the valuation of these instruments do not result in an impact to earnings; however, there may be fair value adjustments related to credit quality variations between counterparties, which may impact earnings as required by FASB ASC 820. As of December 31, 2020, there were no fair value adjustments related to credit quality. Foreign Exchange Forward Contracts. The Corporation enters into foreign exchange forward contracts (“FX forwards”) with customers to exchange one currency for another on an agreed date in the future at an agreed exchange rate. The Corporation then enters into corresponding FX forwards with swap dealer counterparties to economically hedge its exposure on the exchange rate component of the customer agreements. The FX forwards with both the customers and third parties are not designated as hedges under FASB ASC 815 and are marked to market through earnings. Exposure to gains and losses on these contracts increase or decrease over their respective lives as currency exchange and interest rates fluctuate. As the FX forwards are structured to offset each other, changes to the underlying term structure of currency exchange rates considered in the valuation of these instruments do not result in an impact to earnings; however, there may be fair value adjustments related to credit quality variations between counterparties, which may impact earnings as required by FASB ASC 820. As of December 31, 2020, there were no fair value adjustments related to credit quality. Risk Participation Agreements . The Corporation may enter into a risk participation agreement (“RPA”) with another institution as a means to assume a portion of the credit risk associated with a loan structure which includes a derivative instrument, in exchange for fee income commensurate with the risk assumed. This type of derivative is referred to as an “RPA sold.” In addition, in an effort to reduce the credit risk associated with an interest rate swap agreement with a borrower for whom the Corporation has provided a loan structured with a derivative, the Corporation may purchase an RPA from an institution participating in the facility in exchange for a fee commensurate with the risk shared. This type of derivative is referred to as an “RPA purchased.” The following tables detail the derivative instruments as of December 31, 2020 and December 31, 2019: Asset Derivatives Liability Derivatives (dollars in thousands) Notional Fair Notional Fair Derivatives not designated as hedging instruments As of December 31, 2020: Customer derivatives – interest rate swaps $ 1,102,753 $ 113,848 $ 1,102,753 $ 113,848 FX Forwards 9,146 52 9,856 70 RPAs sold — — 33,111 30 RPAs purchased 55,415 342 — — Total derivatives $ 1,167,314 $ 114,242 $ 1,145,720 $ 113,948 As of December 31, 2019: Customer derivatives – interest rate swaps $ 790,209 $ 47,627 $ 790,209 $ 47,627 FX Forwards — — — — RPAs sold — — 4,232 16 RPAs purchased 20,249 90 — — Total derivatives $ 810,458 $ 47,717 $ 794,441 $ 47,643 The Corporation has International Swaps and Derivatives Association agreements with third parties that requires a minimum dollar transfer amount upon a margin call. This requirement is dependent on certain specified credit measures. The amount of collateral posted with third parties at December 31, 2020 and December 31, 2019 was $124.8 million and $63.8 million, respectively. The amount of collateral posted with third parties is deemed to be sufficient to collateralize both the fair market value change as well as any additional amounts that may be required as a result of a change in the specified credit measures. The aggregate fair value of all derivative financial instruments in a liability position with credit measure contingencies and entered into with third parties was $113.2 million and $46.7 million as of December 31, 2020 and December 31, 2019, respectively.

Retirement Benefits [Abstract]
Pension and Postretirement Benefit Plans	Pension and Postretirement Benefit Plans A. General Overview – The Corporation sponsors two non-qualified defined-benefit supplemental executive retirement plans (“SERP I” and “SERP II”) which are restricted to certain senior officers of the Corporation and a postretirement benefit plan (“PRBP”) that covers certain retired employees and a group of current employees. Effective March 31, 2008, the Corporation amended SERP I to freeze further increases in the defined benefit amounts to all participants. Effective March 31, 2013, the Corporation curtailed SERP II, as further increases to the defined benefit amounts to over 20% of the participants were frozen. The PRBP was closed to new participants in 1994. In 2007, the Corporation amended the PRBP to allow for settlement of obligations to certain current and retired employees. Certain retired participant obligations were settled in 2007 and current employee obligations were settled in 2008. The following table provides information with respect to our SERP and PRBP, including benefit obligations and funded status, net periodic pension costs, plan assets, cash flows, amortization information and other accounting items.

Plan Assets: The PRBP, SERP I and SERP II are unfunded plans and, as such, have no related plan assets. F. Cash Flows The following benefit payments, which reflect expected future service, are expected to be paid over the next ten years: (dollars in thousands) SERP I & SERP II PRBP Fiscal year ending 2021 $ 342 $ 43 2022 338 35 2023 346 29 2024 354 24 2025 347 19 2026 - 2030 1,565 46 G. Other Pension and Post Retirement Benefit Information In 2005, the Corporation placed a cap on the future annual benefit payable through the PRBP. This cap is equal to 120% of the 2005 annual benefit. H. Expected Contribution to be Paid in the Next Fiscal Year The 2021 expected contribution for the SERP I and SERP II is $342 thousand. I. Actuarial Losses As indicated in section C of this footnote, the Corporation’s pension plans had cumulative actuarial losses as of December 31, 2020 that will result in an increase in the Corporation’s future pension expense because such losses at each measurement date exceed 10% of the greater of the projected benefit obligation or the market-related value of the plan assets. In accordance with GAAP, net unrecognized gains or losses that exceed that threshold are required to be amortized over the expected service period of active employees, and are included as a component of net pension cost. Amortization of these net actuarial losses has the effect of increasing the Corporation’s pension costs as shown on the table in section D of this footnote.

Tax Law Changes – Impact to Tax Expense With the enactment of the Tax Cuts and Jobs Act (“Tax Reform” or the “Tax Act”) on December 22, 2017, the federal corporate income tax rate was reduced from 35% to 21% effective January 1, 2018. During 2018, we recorded certain tax provision to tax return true-up adjustments associated with items that were finalized as part of our 2017 tax return filing. We recorded a $2.5 million tax benefit in 2018, primarily for deferred tax temporary difference items that were claimed on the 2017 tax return at a 35% federal tax rate that were recorded at December 31, 2017 as anticipating being deducted at a 21% federal tax rate. Also during 2018, as a result of additional purchase accounting adjustments during the year, $611 thousand of such purchase accounting adjustments were charged to income tax expense as a result of reducing their original 35% tax benefit to the new 21% tax rate in effect for 2018. There were no remaining provisional items as of December 31, 2018. Under ASC 740, Income Taxes, the effect of income tax law changes on deferred taxes should be recognized as a component of income tax expense related to continuing operations in the period in which the law is enacted. This requirement applies not only to items initially recognized in continuing operations, but also to items initially recognized in other comprehensive income. The income tax expense recognized as a result of Tax Reform is as follows: Year Ended (dollars in thousands) 2020 2019 2018 Deferred taxes related to items recognized in continuing operations $ — $ — $ (1,895) Deferred taxes on net actuarial loss on defined benefit post-retirement benefit plans — — — Deferred taxes on net unrealized losses on available for sale investment securities — — — Total income tax (benefit) / expense related to Tax Reform $ — $ — $ (1,895) The CARES Act grants potential tax relief and liquidity to businesses, including corporate tax provisions that: temporarily allow for the carryback of net operating losses and remove limitations on the use of loss carryforwards, increase interest expense deduction limitations, and allow accelerated depreciation deductions on certain asset improvements. The tax relief under the CARES Act had no material impact to our Consolidated Financial Statements and related disclosures. E. Other Income Tax Information In accordance with the provisions of ASC 740, “Accounting for Uncertainty in Income Taxes”, management recognizes the financial statement benefit of a tax position only after determining that the Corporation would more likely than not sustain the position following an examination. For tax positions meeting the more-likely-than-not threshold, the amount recognized in the financial statements is the largest benefit that has a greater than 50 percent likelihood of being realized upon settlement with the relevant tax authority. Management applied these criteria to tax positions for which the statute of limitations remained open. There were no reserves for uncertain tax positions recorded during the years ended December 31, 2020, 2019 or 2018. The Corporation is subject to income taxes in the U.S. federal jurisdiction, and in multiple state jurisdictions. The Corporation is no longer subject to U.S. federal income tax examination by tax authorities for the years before 2017. The Corporation’s policy is to record interest and penalties on uncertain tax positions as income tax expense. No interest or penalties were accrued in 2020. As a result of the adoption of ASC 326 on January 1, 2020, the tax impact relating to the incremental provision for expected credit losses from financial assets held at amortized cost has been reflected as a credit to retained earnings to reflect the tax impact of increased credit reserves. Accordingly, $745 thousand of such impact has been reflected as an income tax credit and deferred tax asset on the Corporation's Consolidated Statements of Financial Condition. For further information on the adoption of ASC 326, see Note 2, “Recent Accounting Pronouncements,” in the accompanying Notes to the Consolidated Financial Statements in this Ann ual Report on Form 10-K. As of December 31, 2020, the Corporation has net operating loss (“NOL”) carry-forwards for federal income tax purposes of $30.9 million, all of which relate to the RBPI Merger which are subject to an annual usage limitation of approximately $2.7 million. Management estimates it will be able to utilize an additional $5.0 million per year of the NOLs acquired in the RBPI Merger for a five-year period subsequent to December 15, 2017 due to the existence of net unrealized built-in gains (“NUBIG”) under IRC Section 382, these NOLs will begin to expire in 2030. In addition, the Corporation has alternative minimum tax (“AMT”) credits of $559 thousand, approximately $532 thousand of which are related to the RBPI Merger. The credit amounts do not expire. The amount of AMT credits that can be used per year are limited under IRC section 383. The Corporation has determined that it is more likely than not that the results of future operations will generate sufficient taxable income to realize the deferred tax asset related to these amounts. As a result of the July 1, 2010 merger with FKF, the Corporation succeeded to $2.5 million of tax bad debt reserves that existed at FKF as of June 30, 2010. As of December 31, 2020, the Corporation has not recognized a deferred income tax liability with respect to these reserves. These reserves could be recognized as taxable income and create a current and/or deferred tax liability at the income tax rates then in effect if one of the following conditions occurs: (1) the Bank’s retained earnings represented by this reserve are used for distributions, in liquidation, or for any other purpose other than to absorb losses from bad debts; (2) the Bank fails to qualify as a bank, as provided by the Internal Revenue Code; or (3) there is a change in federal tax law.

A description of the Corporation’s primary revenue streams accounted for under ASC 606 follows: Service Charges on Deposit Accounts: The Corporation earns fees from its deposit customers for transaction-based, account maintenance, and overdraft services. Transaction-based fees, which include services such as ATM use fees, stop payment charges, statement rendering, and ACH fees, are recognized at the time the transaction is executed as that is the point in time the Corporation fulfills the customer’s request. Account maintenance fees, which relate primarily to monthly maintenance, are earned over the course of a month, representing the period over which the Corporation satisfies the performance obligation. Overdraft fees are recognized at the point in time that the overdraft occurs. Service charges on deposits are withdrawn from the customer’s account balance. Wealth Management Fees: The Corporation earns wealth management fee revenue from a variety of sources including fees from trust administration and other related fiduciary services, custody, investment management and advisory services, employee benefit account and IRA administration, estate settlement, tax service fees, shareholder service fees and brokerage. Fees that are determined based on the market value of the assets held in their accounts are generally billed monthly or quarterly, in arrears, based on the market value of assets at the end of the previous billing period. Other related services that are based on a fixed fee schedule are recognized when the services are rendered. Fees that are transaction based, including trade execution services, are recognized at the point in time that the transaction is executed, i.e. the trade date. Included in other assets on the balance sheet is a receivable for wealth management fees that have been earned but not yet collected. Insurance Commissions: The Corporation earns commissions from the sale of insurance policies, which are generally calculated as a percentage of the policy premium, and contingent income, which is calculated based on the volume and performance of the policies held by each carrier. Obligations for the sale of insurance policies are generally satisfied at the point in time which the policy is executed and are recognized at the point in time in which the amounts are known and collection is reasonably assured. Performance metrics for contingent income are generally satisfied over time, not exceeding one year, and are recognized at the point in time in which the amounts are known and collection is reasonably assured. Visa Debit Card Income: The Corporation earns income fees from debit cardholder transactions conducted through the Visa payment network. Fees from cardholder transactions represent a percentage of the underlying transaction value and are recognized daily, concurrently with the transaction processing services provided to the cardholder. Gains/Losses on Sales of OREO: The Corporation records a gain or loss from the sale of OREO when control of the property transfers to the buyer, which generally occurs at the time of an executed deed.

Stock-Based Compensation

Stock-Based Compensation	12 Months Ended

Share-based Payment Arrangement [Abstract]
Stock-Based Compensation	Stock–Based Compensation A. General Information BMBC permits the issuance of stock options, dividend equivalents, performance stock awards, stock appreciation rights and restricted stock units or awards to employees and directors of the Corporation under several plans. The performance awards and restricted awards may be in the form of stock awards or stock units. Stock awards and stock units differ in that for a stock award, shares of restricted stock are issued in the name of the grantee, whereas a stock unit constitutes a promise to issue shares of stock upon vesting. The accounting for awards and units is identical. The terms and conditions of awards under the plans are determined by the Corporation’s Management Development and Compensation Committee. Prior to April 25, 2007, all shares authorized for grant as stock-based compensation were limited to grants of stock options. On April 25, 2007, the shareholders approved BMBC’s “2007 Long-Term Incentive Plan” (the “2007 LTIP”) under which a total of 428,996 shares of BMBC’s common stock were made available for award grants. On April 28, 2010, the shareholders approved BMBC’s “2010 Long Term Incentive Plan” under which a total of 445,002 shares of BMBC’s common stock were made available for award grants, and on April 30, 2015, the shareholders approved an amendment and restatement of such plan (as amended and restated, the “2010 LTIP”) to, among other things, increase the number of shares available for award grants by 500,000 to 945,002. In addition to the shareholder-approved plans mentioned in the preceding paragraph, BMBC periodically authorizes grants of stock-based compensation as inducement awards to new employees. This type of award does not require shareholder approval in accordance with Rule 5635(c)(4) of the Nasdaq listing rules. The equity awards are authorized to be in the form of, among others, options to purchase BMBC’s common stock, time-based restricted stock units (“RSUs”) and performance-based restricted stock units (“PSUs”). RSUs have a restriction based on the passage of time. The grant date fair value of the RSUs is based on the closing price on the date of the grant. PSUs have a restriction based on the passage of time and also have a restriction based on a performance criteria. The performance criteria may be a market-based criteria measured by BMBC’s total shareholder return (“TSR”) relative to the performance of the community bank index for the respective period. The fair value of the PSUs based on BMBC’s TSR relative to the performance of a designated peer group or the NASDAQ Community Bank Index is calculated using the Monte Carlo Simulation method. The performance criteria may also be based on a non-market-based criteria such as return on average equity, return on average common tangible equity or cumulative annual growth rate of EPS, relative to that designated peer group. The grant date fair value of these non-market-based PSUs is based on the closing price of BMBC’s stock on the date of the grant. PSU grants may have a vesting percent ranging from 0% to 150%. The following table summarizes the remaining shares authorized to be granted under the 2010 LTIP: Shares Balance, December 31, 2017 479,953 Grants of RSUs (38,806) Grants of PSUs (40,722) Forfeitures of PSUs 5,679 Forfeitures of RSUs 1,515 Balance, December 31, 2018 407,619 Grants of RSUs (71,716) Grants of PSUs (72,273) Non-vesting PSUs (1) 12,689 PSUs added by performance factor (2) (3,688) Forfeitures of PSUs 17,150 Forfeitures of RSUs 9,461 Balance, December 31, 2019 299,242 Grants of RSUs (26,818) Grants of PSUs (53,685) Forfeitures of PSUs 2,589 Forfeitures of RSUs 1,653 Balance, December 31, 2020 222,981 (1) Non-vesting PSUs represent PSUs that did not meet their performance criteria, were cancelled and are available for future grant. (2) PSUs added by performance factor represent additional PSUs that vested as a result of performance factor exceeding the target performance at which they were granted. B. Fair Value of Options Granted No stock options were granted or assumed during the years ended December 31, 2020, 2019 and 2018. C.

D. RSUs and PSUs BMBC has granted RSUs and PSUs under the 2007 LTIP and 2010 LTIP and in accordance with Rule 5635(c)(4) of the Nasdaq listing standards. RSUs Compensation expense for RSUs is measured based on the market price of the stock on the day prior to the grant date and is recognized on a straight-line basis over the vesting period. For the year ended December 31, 2020, the Corporation recognized $1.7 million of expense related to BMBC’s RSUs. As of December 31, 2020, there was $2.0 million of unrecognized compensation cost related to RSUs. This cost will be recognized over a weighted average period of 1.6 years. During the first quarter of 2019, the Corporation adopted a voluntary Years of Service Incentive Program (the "Incentive Program") which offered certain benefits to eligible employees who met the Incentive Program requirements and voluntarily exited from service with the Corporation during 2019. As part of the Incentive Program, the Corporation elected to waive the service requirement as an RSU vesting condition for employees who held RSUs and chose to participate in the Incentive Program. As a result, 3,494 RSUs were modified which resulted in $112 thousand of incremental expense recognized during the three months ended March 31, 2019. The following table details the RSUs for the years ended December 31, 2020, 2019 and 2018: Year Ended December 31, 2020 2019 2018 Number of Shares Weighted Number of Shares Weighted Number of Shares Weighted Beginning balance 115,466 $ 38.57 76,746 $ 39.71 75,707 $ 35.80 Granted 26,818 36.58 71,716 36.28 38,806 42.23 Vested (25,785) 39.00 (23,535) 34.66 (36,252) 34.38 Forfeited (1,653) 39.12 (9,461) 40.23 (1,515) 36.52 Ending balance 114,846 38.00 115,466 38.57 76,746 39.71 PSUs Compensation expense for PSUs is measured based on their grant date fair value as calculated using either the Monte Carlo Simulation for market-based performance criteria or on the closing price of BMBC’s stock on the date of the grant for non-market-based performance criteria grants and is recognized on a straight-line basis over the vesting period. The grant date fair value of each market-based criteria grant is determined independently using the Monte Carlo Simulation. All 53,685 PSUs granted in 2020 were non-market-based performance criteria grants. The Corporation recognized $1.3 million of expense related to the PSUs for the year ended December 31, 2020. As of December 31, 2020, there was $2.3 million of unrecognized compensation cost related to PSUs. This cost will be recognized over a weighted average period of 1.7 years. As part of the Incentive Program, the Corporation elected to waive the service requirement as a PSU vesting condition for employees who held PSUs and chose to participate in the Incentive Program. As a result, 8,208 PSUs were modified which resulted in $250 thousand of incremental expense recognized during the three months ended March 31, 2019.

Fair Value Measurement

Fair Value Measurement	12 Months Ended
	Dec. 31, 2020
Fair Value Disclosures [Abstract]
Fair Value Measurement	Fair Value Measurement FASB ASC 820, “Fair Value Measurement” defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles and expands disclosures about fair value measurements. FASB ASC 820 also establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy under FASB ASC 820 are: 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 for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active and model derived valuations whose inputs are observable or whose significant value drivers are observable. Level 3 – Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity). A. Assets and liabilities measured on a recurring basis A description of the valuation methodologies used for financial instruments measured at fair value on a recurring basis, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below. Investment Securities The value of the Corporation’s available for sale investment securities, which include obligations of the U.S. government and its agencies, mortgage-backed securities issued by U.S. government- and U.S. government sponsored agencies, obligations of state and political subdivisions, corporate bonds and other debt securities are determined by the Corporation, taking into account the input of an independent third party valuation service provider. The third party’s evaluations are based on market data, utilizing pricing models that vary by asset and incorporate available trade, bid and other market information. For securities that do not trade on a daily basis, their pricing models apply available information such as benchmarking and matrix pricing. The market inputs normally sought in the evaluation of securities include benchmark yields, reported trades, broker/dealer quotes (only obtained from market makers or broker/dealers recognized as market participants), issuer spreads, two-sided markets, benchmark securities, bids, offers and reference data. For certain securities, additional inputs may be used or some market inputs may not be applicable. Inputs are prioritized differently on any given day based on market conditions. Management reviews, annually, the process utilized by its independent third-party valuation service provider. On a quarterly basis, management tests the validity of the prices provided by the third party by selecting a representative sample of the portfolio and obtaining actual trade results, or if actual trade results are not available, competitive broker pricing. On an annual basis, management evaluates, for appropriateness, the methodology utilized by the independent third-party valuation service provider. U.S. Government agencies are evaluated and priced using multi-dimensional relational models and option adjusted spreads. State and municipal securities are evaluated on a series of matrices including reported trades and material event notices. Mortgage-backed securities are evaluated using matrix correlation to treasury or floating index benchmarks, prepayment speeds, monthly payment information and other benchmarks. Other available for sale investments are evaluated using a broker-quote based application, including quotes from issuers. Interest Rate Swaps, FX Forwards, and Risk Participation Agreements The Corporation’s interest rate swaps, FX forwards, and RPAs are reported at fair value utilizing Level 2 inputs. Prices of these instruments are obtained through an independent pricing source utilizing pricing information which may include market observed quotations for swaps, LIBOR rates, forward rates and rate volatility. When entering into a derivative contract, the Corporation is exposed to fair value changes due to interest rate movements, and the potential non-performance of our contract counterparty. The Corporation has developed a methodology to value the non-performance risk based on internal credit risk metrics and the unique characteristics of derivative instruments, which include notional exposure rather than principle at risk and interest payment netting. The results of this methodology are used to adjust the base fair value of the instrument for the potential counterparty credit risk. The following tables present the Corporation’s assets measured at fair value on a recurring basis as of December 31, 2020 and December 31, 2019: As of December 31, 2020 (dollars in thousands) Total Level 1 Level 2 Level 3 Investment securities available for sale: U.S. Treasury securities $ 500,100 $ 500,100 $ — $ — Obligations of U.S. government & agencies 93,098 — 93,098 — Obligations of state & political subdivisions 2,171 — 2,171 — Mortgage-backed securities 453,857 — 453,857 — Collateralized mortgage obligations 19,263 — 19,263 — Collateralized loan obligations 94,404 — 94,404 — Corporate bonds 11,421 — 11,421 — Other investment securities 650 — 650 — Total investment securities available for sale $ 1,174,964 $ 500,100 $ 674,864 $ — Investment securities trading: Mutual funds $ 8,623 $ 8,623 $ — $ — Derivatives: Interest rate swaps 113,848 — 113,848 — FX Forwards 52 — 52 — RPAs purchased 342 — 342 — Total Derivatives $ 114,242 $ — $ 114,242 $ — Total assets measured on a recurring basis at fair value $ 1,297,829 $ 508,723 $ 789,106 $ — As of December 31, 2019 (dollars in thousands) Total Level 1 Level 2 Level 3 Investment securities available for sale: U.S. Treasury securities $ 500,101 $ 500,101 $ — $ — Obligations of U.S. government & agencies 102,020 — 102,020 — Obligations of state & political subdivisions 5,379 — 5,379 — Mortgage-backed securities 366,002 — 366,002 — Collateralized mortgage obligations 31,832 — 31,832 — Other investment securities 650 — 650 — Total investment securities available for sale $ 1,005,984 $ 500,101 $ 505,883 $ — Investment securities trading: Mutual funds $ 8,621 $ 8,621 $ — $ — Derivatives: Interest rate swaps 47,627 — 47,627 — RPAs purchased 90 — 90 Total derivatives $ 47,717 $ — $ 47,717 $ — Total recurring fair value measurements $ 1,062,322 $ 508,722 $ 553,600 $ — There have been no transfers between levels during the year ended December 31, 2020 or December 31, 2019. B. Assets and liabilities measured on a non-recurring basis Fair value is used on a nonrecurring basis to evaluate certain financial assets and financial liabilities in specific circumstances. Similarly, fair value is used on a nonrecurring basis for nonfinancial assets and nonfinancial liabilities such as foreclosed assets, OREO, intangible assets, nonfinancial assets and liabilities evaluated in a goodwill impairment analysis and other nonfinancial assets measured at fair value for purposes of assessing impairment. A description of the valuation methodologies used for financial and nonfinancial assets and liabilities measured at fair value, as well as the general classification of such assets and liabilities pursuant to the valuation hierarchy, is set forth below. Loans and Leases Individually Evaluated for Credit Losses Collateral-dependent loans and leases for which the repayment is expected to be provided substantially through the sale of the collateral and the borrower is experiencing financial difficulty are, in general, individually evaluated for credit losses. Management evaluates and values collateral-dependent loans and leases when management determines that foreclosure is probable or when the borrower is experiencing financial difficulty at the reporting date and repayment is expected to be provided substantially through the operation or sale of the collateral, and the fair values of such loans and leases are estimated using Level 3 inputs in the fair value hierarchy. Each loan’s collateral has a unique appraisal and management’s discount of the value is based on the factors unique to each loan or lease. The significant unobservable input in determining the fair value is management’s subjective discount on appraisals of the collateral securing the loan, which range from 10% - 50%. Collateral may consist of real estate and/or business assets including equipment, inventory and/or accounts receivable and the value of these assets is determined based on the appraisals by qualified licensed appraisers hired by the Corporation. Appraised and reported values may be discounted based on management’s historical knowledge, changes in market conditions from the time of valuation, estimated costs to sell, and/or management’s expertise and knowledge of the client and the client’s business. For loans and leases that are not collateral-dependent, management measures expected credit loss as the difference between the amortized cost basis of the loan and the present value of expected future cash flows discounted at the loan’s effective interest rate. Other Real Estate Owned (“OREO”) OREO consists of properties acquired as a result of foreclosures and deeds in-lieu-of foreclosure. Properties classified as OREO are reported at the lower of cost or fair value less cost to sell, and are classified as Level 3 in the fair value hierarchy. The Corporation did not have any OREO at December 31, 2020 or December 31, 2019. Mortgage Servicing Rights The model to value MSRs estimates the present value of projected net servicing cash flows of the remaining servicing portfolio based on various assumptions, including changes in anticipated loan prepayment rates, the discount rate, reflective of a market participant's required return on an investment for similar assets, and other market-based economic factors. All of these assumptions are considered to be unobservable inputs. Accordingly, MSRs are classified within Level 3 of the fair value hierarchy. The following tables present the Corporation’s assets measured at fair value on a non-recurring basis as of December 31, 2020 and December 31, 2019: As of December 31, 2020 (dollars in thousands) Total Level 1 Level 2 Level 3 Mortgage servicing rights $ 2,632 $ — $ — $ 2,632 Loans and leases individually evaluated for credit losses (1) 11,142 — — 11,142 Total assets measured at fair value on a non-recurring basis $ 13,774 $ — $ — $ 13,774 As of December 31, 2019 (dollars in thousands) Total Level 1 Level 2 Level 3 Mortgage servicing rights $ 4,838 $ — $ — $ 4,838 Impaired loans and leases (1) 15,311 — — 15,311 Total assets measured at fair value on a non-recurring basis $ 20,149 $ — $ — $ 20,149 (1) As further described in Note 2 “Recent Accounting Pronouncements,” in the accompanying Notes to the Consolidated Financial Statements in this Annual Report on Form 10-K, the Corporation adopted ASC 326 using the modified retrospective approach method. The December 31, 2020 balance includes loans and leases individually evaluated for credit losses under the CECL methodology and the December 31, 2019 balance includes impaired loans and leases under previously applicable GAAP. For the year ended December 31, 2020, a net increase of $765 thousand was recorded in the ACL on loans and leases was recorded, and for the year ended December 31, 2019, a net decrease of $44 thousand in the ACL on loans and leases was recorded as a result of adjusting the carrying value and estimated fair value of the collateral-dependent and impaired loans in the above tables.

Fair Value Disclosures [Abstract]
Disclosure about Fair Value of Financial Instruments	Disclosure about Fair Value of Financial Instruments FASB ASC 825, “Disclosures about Fair Value of Financial Instruments” requires disclosure of the fair value information about financial instruments, whether or not recognized in the balance sheet, for which it is practicable to estimate such value. The methodologies for estimating the fair value of financial assets and financial liabilities measured at fair value on a recurring and non-recurring basis are discussed above. The estimated fair value amounts have been determined by management using available market information and appropriate valuation methodologies based on the exit price notion. In cases where quoted market prices are not available, fair values are based on estimates using present value or other market value techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. In that regard, the derived fair value estimates cannot be substantiated by comparison to independent markets and, in many cases, could not be realized in immediate settlement of the instrument. The aggregate fair value amounts presented below do not represent the underlying value of the Corporation. The carrying amount and fair value of the Corporation’s financial instruments are as follows: As of December 31, 2020 2019 (dollars in thousands) Fair Value (1) Carrying Fair Value Carrying Fair Value Financial assets: Cash and cash equivalents Level 1 $ 96,313 $ 96,313 $ 53,931 $ 53,931 Investment securities - available for sale See Note 23 1,174,964 1,174,964 1,005,984 1,005,984 Investment securities - trading See Note 23 8,623 8,623 8,621 8,621 Investment securities – held to maturity Level 2 14,759 15,186 12,577 12,661 Loans held for sale Level 2 6,000 6,000 4,249 4,249 Net portfolio loans and leases Level 3 3,574,702 3,489,322 3,666,711 3,596,268 Mortgage servicing rights Level 3 2,626 2,632 4,450 4,838 Interest rate swaps Level 2 113,848 113,848 47,627 47,627 FX Forwards Level 2 52 52 — — Risk participation agreements purchased Level 2 342 342 90 90 Other assets Level 3 45,847 45,847 52,908 52,908 Total financial assets $ 5,038,076 $ 4,953,129 $ 4,857,148 $ 4,787,177 Financial liabilities: Deposits Level 2 $ 4,376,254 $ 4,379,021 $ 3,842,245 $ 3,842,014 Short-term borrowings Level 2 72,161 72,161 493,219 493,219 Long-term FHLB advances Level 2 39,906 40,441 52,269 52,380 Subordinated notes Level 2 98,883 90,735 98,705 97,199 Junior subordinated debentures Level 2 21,935 27,812 21,753 25,652 Interest rate swaps Level 2 113,848 113,848 47,627 47,627 FX Forwards Level 2 70 70 — — Risk participation agreements sold Level 2 30 30 16 16 Other liabilities Level 3 45,734 45,734 50,251 50,251 Total financial liabilities $ 4,768,821 $ 4,769,852 $ 4,606,085 $ 4,608,358 (1) See Note 23, “Fair Value Measurement,” in the accompanying Notes to the Consolidated Financial Statements in this Annual Report on Form 10-K for a description of hierarchy levels.

Fair Value Disclosures [Abstract]
Financial Instruments with off Balance Sheet Risk, Contingencies and Concentration of Credit Risk	Financial Instruments with Off-Balance Sheet Risk, Contingencies and Concentration of Credit Risk Off-Balance Sheet Risk The Corporation is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit. Those instruments involve, to varying degrees, elements of credit risk in excess of the amount recognized in the consolidated statements of financial condition. The contractual amounts of those instruments reflect the extent of involvement the Corporation has in particular classes of financial instruments. The Corporation’s exposure to credit loss in the event of nonperformance by the counterparty to the financial instrument of commitments to extend credit and standby letters of credit is represented by the contractual amount of those instruments. The Corporation uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet financial instruments. Commitments to extend credit, which include unused lines of credit and unfunded commitments to originate loans, are agreements to lend to a customer as long as there is no violation of any condition established in the agreement. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Some of the commitments are expected to expire without being drawn upon, and the total commitment amounts do not necessarily represent future cash requirements. Total commitments to extend credit at December 31, 2020 were $924.5 million. Management evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Corporation upon extension of credit, is based on a credit evaluation of the counterparty. Collateral varies but may include accounts receivable, marketable securities, inventory, property, plant and equipment, residential real estate, and income-producing commercial properties. Standby letters of credit are conditional commitments issued by the Bank to a customer for a third party. Such standby letters of credits are issued to support private borrowing arrangements. The credit risk involved in issuing standby letters of credit is similar to that involved in extending loan facilities to customers. The collateral varies, but may include accounts receivable, marketable securities, inventory, property, plant and equipment, and residential real estate for those commitments for which collateral is deemed necessary. The Corporation’s obligation under standby letters of credit as of December 31, 2020 was $21.1 million. Contingencies Legal Matters In the ordinary course of its operations, BMBC and its subsidiaries are parties to various claims, litigation, investigations, and legal and administrative cases and proceedings. Such pending or threatened claims, litigation, investigations, legal and administrative cases and proceedings typically entail matters that are considered incidental to the normal conduct of business. Claims for significant monetary damages may be asserted in many of these types of legal actions. Based on the information currently available, the Corporation believes it has meritorious defenses to the claims asserted against it in its currently outstanding legal proceedings and with respect to such legal proceedings, intends to continue to defend itself vigorously, litigating or settling cases according to management’s judgment as to what is in the best interests of BMBC and its shareholders. On a regular basis, liabilities and contingencies in connection with outstanding legal proceedings are assessed utilizing the latest information available. For those matters where it is probable that the Corporation will incur a loss and the amount of the loss can be reasonably estimated, a liability may be recorded in the consolidated financial statements. These legal reserves may be increased or decreased to reflect any relevant developments on at least a quarterly basis. For other matters, where a loss is not probable or the amount or range of the loss is not estimable, legal reserves are not accrued. While the outcome of legal proceedings is inherently uncertain, based on information currently available, advice of counsel and available insurance coverage, management believes that the established legal reserves are adequate and the liabilities arising from legal proceedings will not have a material adverse effect on the consolidated financial position, consolidated results of operations or consolidated cash flows. However, in the event of unexpected future developments, it is possible that the ultimate resolution of these matters, if unfavorable, may be material to the consolidated financial position, consolidated results of operations or consolidated cash flows of the Corporation. Crusader Servicing Corporation (“Crusader”), which was an 80% owned subsidiary of Royal Bank America that was acquired by the Bank in the RBPI Merger, along with the Bank as successor-in-interest to Royal Bank America, are defendants in the case captioned Snyder v. Crusader Servicing Corporation et al., Case No. 2007-01027, in the Court of Common Pleas of Montgomery County, Pennsylvania. The case involves claims brought by a former Crusader shareholder in 2007 against Crusader, its former directors and remaining shareholders related, among other things, to a purported failure to pay amounts allegedly due to Snyder for his shares of Crusader stock. On May 1, 2019, the Court rendered a decision in favor of Snyder and ordered Crusader to pay Snyder the amount of $2,190,000 plus interest at the rate of 6% from December 1, 2006. The matter was appealed, and on March 18, 2020, the Superior Court of the Commonwealth of Pennsylvania returned an opinion reversing in part and affirming in part the trial court's judgment. The effect of this was to vacate the initial judgment awarded by the trial court, and instead to require an appraisal process in accordance with Crusader's Shareholders' Agreement to determine the value of Mr. Snyder's shares. The parties anticipate the appraisal to commence within the coming months. We do not believe that this ruling and the monetary award, if any, ultimately payable by Crusader will be material to the consolidated financial position, consolidated results of operations or consolidated cash flows of the Corporation. Indemnifications In general, the Corporation does not sell loans with recourse, except to the extent that it arises from standard loan-sale contract provisions. These provisions cover violations of representations and warranties and, under certain circumstances, first payment default by borrowers. These indemnifications may include the repurchase of loans by the Corporation and are considered customary provisions in the secondary market for conforming mortgage loan sales. Repurchases and losses have been rare and no provision is made for losses at the time of sale. There were no such repurchases for the year ended December 31, 2020. As of December 31, 2020, there was one pending and unsettled loan repurchase demand of approximately $200 thousand. Concentrations of Credit Risk The Corporation has a material portion of its loans in real estate-related loans. A predominant percentage of the Corporation’s real estate exposure, both commercial and residential, is in the Corporation’s primary trade area, which includes portions of Delaware, Chester, Montgomery and Philadelphia counties in Southeastern Pennsylvania. Management is aware of this concentration and attempts to mitigate this risk to the extent possible in many ways, including the underwriting and assessment of borrower’s capacity to repay. See Note 5, “Loans and Leases,” in the accompanying Notes to the Consolidated Financial Statements in this Annual Report on Form 10-K for additional information.

Dividend Restrictions

Dividends [Abstract]
Dividend Restrictions	Dividend Restrictions The Bank is subject to the Pennsylvania Banking Code of 1965 (the “Code”), as amended, and is restricted in the amount of dividends that can be paid to its sole shareholder, BMBC. The Code restricts the payment of dividends by the Bank to the amount of its net income during the current calendar year and the retained net income of the prior two calendar years, unless the dividend has been approved by the Federal Reserve Board. Accordingly, the dividend payable by the Bank to BMBC beginning on January 1, 2021 is limited to net income not yet earned in 2021 plus the Bank’s total retained net income for the combined two years ended December 31, 2019 and 2020 of $15.8 million. The Bank issued $35.0 million and $32.0 million of dividends to BMBC during the years ended December 31, 2020 and December 31, 2019, respectively. The amount of dividends paid by the Bank may not exceed a level that reduces capital levels to below levels that would cause the Bank to be considered less than adequately capitalized as detailed in Note 28 – “Regulatory Capital Requirements.”

Regulatory Capital Requirements

Broker-Dealer, Net Capital Requirement, SEC Regulation [Abstract]
Regulatory Capital Requirements	Regulatory Capital Requirements A. General Regulatory Capital Information Both BMBC and the Bank are subject to various regulatory capital requirements, administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if taken, could have a direct material effect on BMBC and the Bank’s consolidated financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, BMBC and the Bank must meet specific capital guidelines that involve quantitative measures of their assets, liabilities and certain off-balance-sheet items as calculated under regulatory accounting practices. The capital amounts and classifications 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. Beginning in 2015, new regulatory capital reforms, known as Basel III, issued as part of the Dodd-Frank Act began to be phased in. For more information, refer to the section titled Capital Adequacy within Item 1 - Business - Supervision and Regulation beginning at page 6 in this Form 10-K. B. S-3 Shelf Registration Statement and Offerings Thereunder In May 2018, BMBC filed a shelf registration statement on Form S-3, SEC File No. 333-224849 (the “Shelf Registration Statement”). The Shelf Registration Statement allows BMBC to raise additional capital from time to time through offers and sales of registered securities consisting of common stock, debt securities, warrants, purchase contracts, rights and units or units consisting of any combination of the foregoing securities. BMBC may sell these securities using the prospectus in the Shelf Registration Statement, together with applicable prospectus supplements, from time to time, in one or more offerings. In addition, BMBC has in place under its Shelf Registration Statement a Dividend Reinvestment and Stock Purchase Plan (the “Plan”), which allows it to issue up to 1,500,000 shares of registered common stock. The Plan allows for the grant of a request for waiver (“RFW”) above the Plan’s maximum investment of $120 thousand per account per year. An RFW is granted based on a variety of factors, including the Corporation’s current and projected capital needs, prevailing market prices of BMBC’s common stock and general economic and market conditions. For the year ended December 31, 2020, BMBC did not issue any shares through the Plan, nor were any RFWs approved. The Plan administrator conducted dividend reinvestments for Plan participants through open market purchases. No other sales of equity securities were executed under the Shelf Registration Statement during the year ended December 31, 2020. C. Share Repurchases On August 6, 2015, BMBC announced a stock repurchase program (the “2015 Program”) pursuant to which BMBC may repurchase up to 1,200,000 shares of its common stock, at an aggregate purchase price not to exceed $40 million. During the year ended December 31, 2019, 40,016 shares were repurchased under the 2015 Program at an average price of $38.12. On April 18, 2019, BMBC announced a new stock repurchase program (the “2019 Program”) pursuant to which BMBC may repurchase up to 1,000,000 shares of its common stock. Under the 2019 Program, BMBC may repurchase its common stock at any price, but the aggregate purchase price is not to exceed $45 million. The 2019 Program became effective in the second quarter of 2019 upon the completion of BMBC’s existing 2015 Program. During the years ended December 31, 2020 and 2019, 207,201 and 82,767 shares, respectively, were repurchased under the 2019 Program at an average price of $34.99 and $36.22, respectively. All share repurchases were accomplished in open market transactions. As of December 31, 2020, the maximum number of shares remaining authorized for repurchase under the 2019 Program was 710,032, at an aggregate purchase price not to exceed $34.8 million. In addition, it is BMBC’s practice to retire shares to its treasury account upon the vesting of stock awards to certain officers, in order to cover the statutory income tax withholdings related to such vesting. D. Regulatory Capital Ratios As set forth in the following table, quantitative measures have been established to ensure capital adequacy ratios required of both BMBC and the Bank. As of December 31, 2020 and 2019, BMBC and the Bank had met all capital adequacy requirements to which they were subject. Federal banking regulators have defined specific capital categories, and categories range from a best of “well capitalized” to a worst of “critically under-capitalized.” The capital ratios for both BMBC and the Bank indicate levels above the regulatory minimum to be considered “well capitalized” as of December 31, 2020 and 2019. In September 2020, the U.S. banking agencies issued a final rule that provides banking organizations with an alternative option to delay for two years an estimate of CECL’s effect on regulatory capital, relative to the incurred loss methodology’s effect on regulatory capital, followed by a three-year transition period. This final rule is consistent with the interim final rule issued by the U.S. banking agencies in March 2020. The December 31, 2020 ratios reflect the Corporation's election of the five-year transition provision. The following table presents BMBC's and the Bank’s regulatory capital ratios and the minimum capital requirements for the Bank to be considered “Well Capitalized” by regulators as of December 31, 2020 and 2019: Actual Minimum (dollars in thousands) Amount Ratio Amount Ratio December 31, 2020 Total capital to risk weighted assets: BMBC $ 583,057 15.55 % $ 375,045 10.00 % Bank $ 477,792 12.75 % $ 374,758 10.00 % Tier I capital to risk weighted assets: BMBC $ 444,640 11.86 % $ 300,036 8.00 % Bank $ 432,258 11.53 % $ 299,807 8.00 % Common equity Tier I risk weighted assets: BMBC $ 423,475 11.29 % $ 243,779 6.50 % Bank $ 432,258 11.53 % $ 243,593 6.50 % Tier I leverage ratio (Tier I capital to total quarterly average assets): BMBC $ 444,640 9.04 % $ 246,002 5.00 % Bank $ 432,258 8.79 % $ 245,837 5.00 % December 31, 2019 Total capital to risk weighted assets: BMBC $ 547,440 14.69 % $ 372,690 10.00 % Bank $ 450,212 12.09 % $ 372,435 10.00 % Tier I capital to risk weighted assets: BMBC $ 425,773 11.42 % $ 298,152 8.00 % Bank $ 427,250 11.47 % $ 297,948 8.00 % Common equity Tier I to risk weighted assets: BMBC $ 404,715 10.86 % $ 242,249 6.50 % Bank $ 427,250 11.47 % $ 242,083 6.50 % Tier I leverage ratio (Tier I capital to total quarterly average assets): BMBC $ 425,773 9.33 % $ 228,216 5.00 % Bank $ 427,250 9.37 % $ 227,997 5.00 %

Segment Reporting [Abstract]
Segment Information	Segment Information FASB Codification 280 – “Segment Reporting” identifies operating segments as components of an enterprise which are evaluated regularly by the Corporation’s chief operating decision maker, our Chief Executive Officer, in deciding how to allocate resources and assess performance. The Corporation has applied the aggregation criterion set forth in this codification to the results of its operations. The Corporation’s Banking segment consists of commercial and retail banking. The Banking segment is evaluated as a single strategic unit which generates revenues from a variety of products and services. The Banking segment generates interest income from its lending (including leases) and investing activities and is dependent on the gathering of lower cost deposits from its branch network or borrowed funds from other sources for funding its loans, resulting in the generation of net interest income. The Banking segment also derives revenues from other sources including gains on the sale in available for sale investment securities, gains on the sale of residential mortgage loans, service charges on deposit accounts, cash sweep fees, overdraft fees, BOLI income and interchange revenue associated with its Visa Check Card offering. Also included in the Banking segment are two subsidiaries of the Bank, KCMI Capital, Inc. and Bryn Mawr Equipment Financing, Inc., both of which provide specialized lending solutions to our customers. The Wealth Management segment has responsibility for a number of activities within the Corporation, including trust administration, other related fiduciary services, custody, investment management and advisory services, employee benefits and IRA administration, estate settlement, tax services and brokerage. The Bryn Mawr Trust Company of Delaware is included in the Wealth Management segment of the Corporation since it has similar economic characteristics, products and services to those of the Wealth Management Division of the Corporation. BMT Investment Advisers, formed in May 2017, served as investment adviser to BMT Investment Funds, a Delaware statutory trust, prior to its wind-down in the second quarter of 2020, is also reported under the Wealth Management segment. Effective January 1, 2020, the business of Lau Associates, which is reported in the Wealth Management segment, was transitioned into the Wealth Management Division of the Bank, also reported in the Wealth Management segment. In addition, the Wealth Management Division oversees all insurance services of the Corporation, which are conducted through the Bank’s insurance subsidiary, BMT Insurance Advisors, Inc., and are reported in the Wealth Management segment. The accounting policies of the Corporation are applied by segment in the following tables. The segments are presented on a pre-tax basis. The following table details the Corporation’s segments: As of or for the Year Ended December 31, 2020 2019 2018 (dollars in thousands) Banking Wealth Consolidated Banking Wealth Consolidated Banking Wealth Consolidated Net interest income $ 143,784 $ 3 $ 143,787 $ 147,635 $ 6 $ 147,641 $ 149,464 $ 7 $ 149,471 Provision for credit losses 41,677 — 41,677 8,595 — 8,595 7,089 — 7,089 Net interest income after provision for credit losses 102,107 3 102,110 139,040 6 139,046 142,375 7 142,382 Noninterest income: Fees for wealth management services — 44,532 44,532 — 44,400 44,400 — 42,326 42,326 Insurance commissions — 5,911 5,911 — 6,877 6,877 — 6,808 6,808 Capital markets revenue 9,491 — 9,491 11,276 — 11,276 4,848 — 4,848 Service charges on deposit accounts 2,868 — 2,868 3,374 — 3,374 2,989 — 2,989 Loan servicing and other fees 1,646 — 1,646 2,206 — 2,206 2,259 — 2,259 Net gain on sale of loans 5,779 — 5,779 2,342 — 2,342 3,283 — 3,283 Net gain on sale of investment securities available for sale — — — — — — 7 — 7 Net gain on sale of long-lived assets 2,297 — 2,297 — — — — — — Net gain (loss) on sale of OREO 148 — 148 (84) — (84) 295 — 295 Other operating income 9,171 128 9,299 11,687 106 11,793 12,981 186 13,167 Total noninterest income 31,400 50,571 81,971 30,801 51,383 82,184 26,662 49,320 75,982 Noninterest expenses: Salaries & wages 47,404 21,442 68,846 54,076 20,295 74,371 46,936 19,735 66,671 Employee benefits 9,105 3,500 12,605 9,572 3,884 13,456 9,046 3,872 12,918 Occupancy and bank premise 10,738 1,989 12,727 10,547 2,044 12,591 9,588 2,011 11,599 Impairment of long-lived assets 1,605 — 1,605 — — — — — — Amortization of intangible assets 1,109 2,458 3,567 1,309 2,492 3,801 1,555 2,101 3,656 Professional fees 5,547 881 6,428 4,840 594 5,434 3,747 456 4,203 Other operating expenses 31,709 5,240 36,949 30,511 6,263 36,774 36,032 5,328 41,360 Total noninterest expenses 107,217 35,510 142,727 110,855 35,572 146,427 106,904 33,503 140,407 Segment profit 26,290 15,064 41,354 58,986 15,817 74,803 62,133 15,824 77,957 Intersegment (revenues) expenses (1) (622) 622 — (613) 613 — (715) 715 — Pre-tax segment profit after eliminations $ 25,668 $ 15,686 $ 41,354 $ 58,373 $ 16,430 $ 74,803 $ 61,418 $ 16,539 $ 77,957 % of segment pre-tax profit after eliminations 62.1 % 37.9 % 100.0 % 78.0 % 22.0 % 100.0 % 78.8 % 21.2 % 100.0 % Segment assets (dollars in millions) $ 5,384.4 $ 47.6 $ 5,432.0 $ 5,210.4 $ 52.9 $ 5,263.3 $ 4,601.7 $ 50.8 $ 4,652.5 (1) Inter-segment revenues consist of rental payments, interest on deposits and management fees.

Accounting Policies [Abstract]
Nature of Business	Nature of Business The Bryn Mawr Trust Company (the “Bank”) received its Pennsylvania banking charter in 1889 and is a member of the Federal Reserve System. In 1986, Bryn Mawr Bank Corporation (“BMBC”) was formed and on January 2, 1987, the Bank became a wholly-owned subsidiary of BMBC. The Bank and BMBC are headquartered in Bryn Mawr, Pennsylvania, located in the western suburbs of Philadelphia. BMBC and its direct and indirect subsidiaries (collectively, the “Corporation”) offer a full range of personal and business banking services, consumer and commercial loans, equipment leasing, mortgages, insurance and wealth management services, including investment management, trust and estate administration, retirement planning, custody services, and tax planning and preparation from 41 banking locations, seven wealth management offices and two insurance and risk management locations in the following counties: Montgomery, Chester, Delaware, Philadelphia, and Dauphin Counties in Pennsylvania; New Castle County in Delaware; and Mercer and Camden Counties in New Jersey. The common stock of BMBC trades on the NASDAQ Stock Market (“NASDAQ”) under the symbol BMTC.
Basis of Presentation and Principles of Consolidation	Basis of Presentation and Principles of Consolidation The accounting policies of the Corporation conform to U.S. generally accepted accounting principles (“GAAP”). The Consolidated Financial Statements include the accounts of BMBC and its consolidated subsidiaries. BMBC’s primary subsidiary is the Bank. The Corporation’s consolidated financial condition and results of operations consist almost entirely of the Bank’s financial condition and results of operations. In connection with the RBPI Merger, the Corporation acquired two Delaware trusts, Royal Bancshares Capital Trust I and Royal Bancshares Capital Trust II. These two entities are not consolidated per requirements under Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 810, “Consolidation” (“ASC Topic 810”). All significant intercompany balances and transactions are eliminated in consolidation and certain reclassifications are made when necessary in order to conform the previous years' consolidated financial statements to the current year's presentation. In preparing the Consolidated Financial Statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the dates of the balance sheets, and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from these estimates. Although our current estimates contemplate current conditions and how we expect them to change in the future, it is reasonably possible that in 2021 actual conditions could be worse than anticipated in those estimates, which could materially affect our
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents include cash, interest-bearing and noninterest-bearing amounts due from banks, and federal funds sold.
Investment Securities	Investment Securities Investment securities which are held for indefinite periods of time, which the Corporation intends to use as part of its asset/liability strategy, or which may be sold in response to changes in credit quality of the issuer, interest rates, changes in prepayment risk, increases in capital requirements, or other similar factors, are classified as available for sale and are carried at fair value. Net unrealized gains and losses for such securities, net of tax, are required to be recognized as a separate component of shareholders’ equity and excluded from determination of net income. Gains or losses on disposition are based on the net proceeds and cost of the securities sold, adjusted for the amortization of premiums and accretion of discounts, using the specific identification method. Investments for which management has the intent and ability to hold until maturity are classified as held to maturity and are carried at their amortized cost on the balance sheet. No adjustment for market value fluctuations are recorded related to the held to maturity portfolio. Investment securities held in trading accounts consist of deferred compensation trust accounts, which are invested in listed mutual funds whose diversification is at the discretion of the deferred compensation plan participants. Investment securities held in trading accounts are reported at fair value, with adjustments in fair value reported through income.
ACL on Available for Sale Securities and Held to Maturity Securities	ACL on Available for Sale Securities For available for sale debt securities in an unrealized loss position, management first assesses whether it intends to sell, or it is more likely than not it will be required to sell the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the security’s amortized cost basis is written down to fair value through income. For available for sale debt securities that do not meet the aforementioned criteria, management evaluates whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, management considers the extent to which fair value is less than amortized cost, any explicit or implicit guarantees by the U.S. government, any changes to the rating of the security by the rating agency, and adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost basis. Any impairment that has not been recorded through an allowance for credit loss is recognized in other comprehensive income. Changes in the ACL on available for sale debt securities are recorded as provision for (or release of) credit loss expense. Losses are charged against the ACL on available for sale debt securities when management believes the uncollectibility of an available for sale security is confirmed or when either of the criteria regarding intent or requirement to sell is met. Accrued interest receivable on available for sale debt securities, which is reported in Accrued interest receivable on the Consolidated Balance Sheet, totaled $2.0 million at December 31, 2020 and is excluded from the estimate of credit losses. F. ACL on Held to Maturity Securities Management measures expected credit losses on held to maturity debt securities on a collective basis by major security type. The Corporation’s held to maturity debt securities consist of mortgage-backed securities issued by U.S. government entities and agencies. These securities are either explicitly or implicitly guaranteed by the U.S. government, are highly rated by major rating agencies and have a long history of no credit losses. With respect to these securities, management considers the history of credit losses, current conditions and reasonable and supportable forecasts, which may indicate that the expectation that nonpayment of the amortized cost basis is or continues to be zero, even if the U.S. government were to default. Therefore, for those securities, the Corporation does not record expected credit losses. Accrued interest receivable on held to maturity debt securities, which is reported in Accrued interest receivable on the Consolidated Balance Sheet, totaled $37 thousand as of December 31, 2020 and is excluded from the estimate of credit losses.
Loans Held for Sale	Loans Held for Sale Mortgage loans originated and intended for sale in the secondary market are carried at the lower of cost or fair value in the aggregate. Net unrealized temporary losses, if any, are recognized through a valuation allowance by charges to income.
Portfolio Loans and Leases	Portfolio Loans and Leases The Corporation originates construction, Commercial & Industrial, commercial mortgage, residential mortgage, home equity and consumer loans to customers primarily in southeastern Pennsylvania, as well as small-ticket equipment leases to customers nationwide. Although the Corporation has a diversified loan and lease portfolio, its debtors’ ability to honor their contracts is substantially dependent upon the real estate and general economic conditions of the region. Loans and leases that management has the intention and ability to hold for the foreseeable future, or until maturity or pay-off, generally are reported at their outstanding principal balance adjusted for charge-offs, the allowance for credit losses on loans and leases and any deferred fees or costs on originated loans and leases. Interest income is accrued on the unpaid principal balance. Loan and lease origination fees and loan and lease origination costs are deferred and recognized as an adjustment to the related yield using the interest method. The accrual of interest on loans and leases is generally discontinued at the time the loan is 90 days delinquent unless the credit is well secured and in the process of collection. Loans and leases are placed on nonaccrual status or charged-off at an earlier date if collection of principal or interest is considered doubtful. All interest accrued, but not collected for loans that are placed on nonaccrual status or charged-off is charged against interest income. All interest accrued, but not collected, on leases that are placed on nonaccrual status is not charged against interest income until the lease becomes 120 days delinquent, at which point it is charged off. The interest received on these nonaccrual loans and leases is applied to reduce the carrying value of loans and leases. Loans and leases are returned to accrual status when all the principal and interest amounts contractually due are brought current and remain current for at least six months, and future payments are reasonably assured. Once a loan returns to accrual status, any interest payments collected during the nonaccrual period which had been applied to the principal balance are reversed and recognized as interest income over the remaining term of the loan. Purchased loans and leases which have experienced more than insignificant credit deterioration since origination, purchased credit deteriorated (“PCD”) loans and leases, are recorded at the amount paid. An ACL is determined using the same methodology as other portfolio loans and leases. The initial ACL determined on a collective basis is allocated to individual loans. The loan’s purchase price is grossed-up by adding the allocated ACL to arrive at its initial amortized cost basis. The difference between the initial amortized cost basis and the par value of the loan or lease is a noncredit discount or premium, which is amortized into interest income over the life of the loan or lease. Subsequent changes to the ACL associated with PCD loans or leases are recorded through provision expense.
ACL on Loans and Leases	ACL on Loans and Leases The ACL on loans and leases represents management’s estimate of all expected credit losses over the expected contractual life of our existing portfolio loans and leases. Determining the appropriateness of the ACL on loans and leases is complex and requires judgment by management about the effect of matters that are inherently uncertain. Subsequent evaluations of the then-existing loan portfolio, in light of the factors then prevailing, may result in significant changes in the ACL on loans and leases in those future periods. The provision for credit losses recorded through earnings is the amount necessary to maintain the ACL on loans and leases at the amount of expected credit losses within the loans and leases portfolio. The amount of expense and the corresponding level of ACL on loans and leases are based on management’s evaluation of the collectability of the loan and lease portfolio based on historical loss experience, reasonable and supportable forecasts, and other significant qualitative and quantitative factors not captured in the historical loss experience. The ACL on loans and leases, as reported in our Consolidated Statements of Financial Condition, is adjusted by an expense for credit losses, which is recognized in earnings, and reduced by the charge-off of loan and lease amounts, net of recoveries. For further information on the ACL on loans and leases, see Note 5 - Loans and Leases in the accompanying Notes to Consolidated Financial Statements. Management employs a disciplined process and methodology to establish the ACL on loans and leases that has two basic components: first, a collective (pooled) component for estimated expected credit losses for pools of loans and leases that share similar risk characteristics; and second, an asset-specific component involving individual loans and leases that do not share risk characteristics with other loans and leases and the measurement of expected credit losses for such individual loans. Based upon this methodology, management establishes an asset-specific ACL on loans and leases that do not share risk characteristics with other loans and leases, which generally include nonaccrual loans and leases, TDRs, and PCD loans. The asset-specific ACL is based on the amount of expected credit losses calculated on those loans and leases and amounts determined to be uncollectible are charged off. Factors we consider in measuring the extent of expected credit loss include payment status, collateral value, borrower financial condition, guarantor support and the probability of collecting scheduled principal and interest payments when due. When a loan or lease does not share risk characteristics with other loans or leases, they are individually evaluated for expected credit loss. For loans and leases that are not collateral-dependent, management measures expected credit loss as the difference between the amortized cost basis of the loan and the present value of expected future cash flows discounted at the loan’s effective interest rate. For collateral-dependent loans and leases, expected credit loss is measured as the difference between the amortized cost basis of the loan and the fair value of the underlying collateral. The fair value of the collateral is adjusted for the estimated cost to sell if repayment or satisfaction of a loan is dependent on the sale (rather than only on the operation) of the collateral. If the calculated expected credit loss is determined to be permanent, fixed or nonrecoverable, the credit loss portion of the loan will be charged off against the ACL on loans and leases. Loans and leases designated as having significantly increased credit risk are generally placed on nonaccrual and remain in that status until all principal and interest payments are current and the prospects for future payments in accordance with the loan agreement are reasonably assured, at which point the loan is returned to accrual status. In estimating the component of the ACL on loans and leases that share common risk characteristics, loans and leases are segregated into portfolio segments based on federal call report codes which classify loans and leases based on the primary collateral supporting the loan and lease. Methods utilized by management to estimate expected credit losses include 1) a discounted cash flow (“DCF”) methodology that discounts instrument-level contractual cash flows, adjusted for prepayments and curtailments, incorporating loss expectations, and 2) a weighted average remaining maturity (“WARM”) methodology which contemplates expected losses at a pool-level, utilizing historic loss information. Under both methodologies, management estimates the ACL on loans and leases using relevant available information, from internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts. After the end of the reasonable and supportable forecast period, the loss rates revert to the long-term mean loss rate, or in the case of an input-driven predictive method, the long-term mean of the input, using a reversion period where applicable. Historical credit loss experience, including examination of loss experience at representative peer institutions when the Corporation’s own loss history does not result in estimations that are meaningful to users of the Corporation’s Consolidated Financial Statements, provides the basis for the estimation of expected credit losses. Adjustments to historical loss information are considered for differences in current loan-specific risk characteristics such as differences in underwriting standards, portfolio mix, delinquency level, or term as well as for changes in environmental conditions, such as changes in unemployment rates, property values, or other relevant factors. The DCF methodology uses inputs of current and forecasted macroeconomic indicators to predict future loss rates. The current macroeconomic indicator utilized by the bank is the Pennsylvania unemployment rate. In building the current expected credit loss (“CECL”) model utilized in the DCF methodology, a correlation between this indicator and historic loss levels was developed, enabling a prediction of future loss rates related to future Pennsylvania unemployment rates. The portfolio segments utilizing the DCF methodology as of December 31, 2020 included: CRE - owner-occupied and nonowner-occupied loans, home equity lines of credit, residential mortgages (first and junior liens), construction loans and consumer loans. The WARM methodology uses combined historic loss rates for the Bank and peer institutions, if necessary, gathered from Call Report filings. The selected period for which historic loss rates are used is dependent on management's evaluation of current conditions and expectations of future loss conditions. The portfolio segments utilizing the WARM methodology as of December 31, 2020 included Commercial & Industrial loans and leases. For those loans and leases where the ACL is measured on a collective (pool) basis, management has identified the following portfolio segments based on federal call report codes which classify loans and leases based on the primary collateral supporting the loan or lease: Commercial real estate (“CRE”) loans (owner-occupied and non-owner occupied): The Bank originates mortgage loans for multifamily properties (i.e. buildings which have five or more residential units) and other commercial real estate that is either owner-occupied or managed as an investment property (non-owner occupied) primarily within Pennsylvania, Delaware and Southern and Central New Jersey. Commercial real estate properties primarily include retail buildings/shopping centers, hotels, office/medical buildings and industrial/warehouse space. Multifamily loans are expected to be repaid from the cash flows of the underlying property so the collective amount of rents must be sufficient to cover all operating expenses, property management and maintenance, taxes and debt service. Increases in vacancy rates, interest rates or other changes in general economic conditions can have an impact on the borrower and its ability to repay the loan. Commercial real estate loans are generally considered to have a higher degree of credit risk than multifamily loans as they may be dependent on the ongoing success and operating viability of a fewer number of tenants who are occupying the property and who may have a greater degree of exposure to economic conditions. Home equity lines of credit: The Bank originates the majority of its home equity lines of credit through its retail channel. The primary risk characteristics associated with home equity lines of credit typically involve major living or lifestyle changes to the borrower, including unemployment or other loss of income; unexpected significant expenses, such as major medical expenses, catastrophic events, divorce and death. Home equity lines of credit are typically originated with variable or floating interest rates, which could expose the borrower to higher payments in a rising interest rate environment. Real estate values could decrease and cause the value of the underlying property to fall below the loan amount, creating additional potential loss exposure for the Bank. Residential mortgages secured by first liens: The Bank originates one-to-four family residential mortgage loans primarily within Pennsylvania, Delaware and Southern and Central New Jersey. These loans are secured by first liens on a primary residence or investment property. The risks associated with residential mortgage loans typically involve major living or lifestyle changes to the borrower, including unemployment or other loss of income; unexpected significant expenses, such as major medical expenses, catastrophic events, divorce or death. Residential mortgage loans that have adjustable rates could expose the borrower to higher payments in a rising interest rate environment. Real estate values could decrease and cause the value of the underlying property to fall below the loan amount, creating additional potential loss exposure for the Bank. Residential mortgages secured by junior liens: The Bank originates loans secured by junior liens against one to four family properties primarily within Pennsylvania, Delaware and Southern and Central New Jersey. Loans secured by junior liens are primarily in the form of an amortizing home equity loan. These loans are subordinate to a first mortgage which may be from another lending institution. The risks associated with loans secured by junior liens typically involve major living or lifestyle changes to the borrower, including unemployment or other loss of income, unexpected significant expenses, such as for major medical expenses, catastrophic events, divorce or death. Real estate values could decrease and cause the value of the property to fall below the loan amount, creating additional potential loss exposure for the Bank. Construction: The Bank originates construction loans to finance land development preparatory to erecting new structures or the on-site construction of industrial, commercial, or residential buildings. Construction loans include not only construction of new structures, but also additions or alterations to existing structures and the demolition of existing structures to make way for new structures. Construction loans are generally secured by real estate. The risks are typically specific to the uncertainty on whether the construction will be completed according to the specifications and schedules. Factors that may influence the completion of construction may be customer specific, such as the quality and depth of property management, or related to changes in general economic conditions. Commercial & Industrial: The Bank originates lines of credit and term loans to operating companies for business purposes. The loans are generally secured by business assets such as accounts receivable, inventory, business vehicles and equipment as well as the stock of a company, if privately held. Commercial & Industrial loans are typically repaid first by the cash flows generated by the borrower’s business operations. The risks are typically specific to the underlying business and its ability to generate sustainable profitability and positive cash flow. Factors that may influence a borrower's ability to repay their loan include demand for the business’ products or services, the quality and depth of management, the degree of competition, regulatory changes, and general economic conditions. The ability of the Bank to foreclose and realize sufficient value from business assets securing these loans is often uncertain. To mitigate the risk characteristics of Commercial & Industrial loans, commercial real estate may be included as a secondary source of collateral. The Bank will often require more frequent reporting requirements from the borrower in order to better monitor its business performance. Consumer: The Bank originates or lines of credit to individuals for household, family, and other personal expenditures as well as overdrawn customer deposit balances which are reported as loans. This also represents all other loans that cannot be categorized in any of the previous mentioned loan segments. Consumer loans generally have higher interest rates and shorter terms than residential loans but tend to have higher credit risk due to the type of collateral securing the loan or in some cases the absence of collateral. Leases: The Bank’s wholly-owned subsidiary Bryn Mawr Equipment Financing, Inc. specializes in equipment leases for small- and mid-sized businesses nationally and across a broad range of industries. The Bank’s credit risk generally results from the potential default of borrowers or lessees, which may be driven by customer specific or broader industry related conditions. Accrued interest receivable on loans and leases, which is reported in Accrued interest receivable on the Consolidated Balance Sheet, totaled $12.1 million as of December 31, 2020 and is excluded from the estimate of credit losses due to our charge-off policy to reverse accrued interest in a timely manner on loans and leases that are 90-days past due and deemed nonperforming. However, the Corporation continued to accrue interest on loans and leases for which payment deferrals have been extended to borrowers affected by the COVID-19 pandemic. Deferrals under the Corporation's modification program may be for durations which exceed the Corporation’s 90-day write-off policy for accrued interest. Therefore, these interest deferrals do not qualify for the Corporation’s election to not recognize a credit loss allowance for credit losses on accrued interest receivable. Accordingly, as of December 31, 2020, the Corporation has estimated credit losses for COVID-19 interest deferrals of $64 thousand, which is included as a reduction to Accrued interest receivable on the Consolidated Balance Sheet and Provision for credit losses on the Consolidated Income Statement. Prior to January 1, 2020 As further described in Note 2, “Recent Accounting Pronouncements,” in the accompanying Notes to the Consolidated Financial Statements in this Annual Report on Form 10-K , on January 1, 2020, the Corporation adopted ASU 2016-13 (Topic 326), “Measurement of Credit Losses on Financial Instruments,” which replaces the incurred loss methodology with an expected loss methodology that is referred to as the current expected credit loss (or CECL) methodology. Prior to the adoption of ASC 326 on January 1, 2020, the ACL on loans and leases was maintained at a level that the Corporation believed was sufficient to absorb estimated potential credit losses. Management’s determination of the adequacy of the ACL on loans and leases was based on guidance provided in ASC 450 – Contingencies and ASC 310 - Receivables, and involved the periodic evaluations of the loan and lease portfolio and other relevant factors. However, this evaluation was inherently subjective as it required significant estimates by management. Consideration was given to a variety of factors in establishing these estimates. Quantitative factors in the form of historical net charge-off rates by portfolio segment were considered. In connection with these quantitative factors, management established what it deems to be an adequate look-back period (“LBP”) for the charge-off history. As of December 31, 2019, management utilized a five-year LBP, which it believes adequately captures the trends in charge-offs. In addition, management developed an estimate of a loss emergence period (“LEP”) for each segment of the loan portfolio based on analyses of actual charge-offs tracked back in time to the triggering event for the eventual loss. The LEP estimates the time between the occurrence of a loss event for a borrower and an actual charge-off of a loan. In addition, various qualitative factors were considered, including the specific terms and conditions of loans, changes in underwriting standards, delinquency statistics, industry concentrations and overall exposure of a single customer. In addition, consideration was given to the adequacy of collateral, the dependence on collateral, and the results of internal loan reviews, including a borrower’s financial strengths, their expected cash flows, and their access to additional funds. As part of the process of calculating the ACL on loans and leases for the different segments of the loan and lease portfolio, management considered certain credit quality indicators, including risk grades assigned to each loan and the performance/non-performance status of a loan. Prior to January 1, 2020, a loan or lease was considered impaired when, based on current information, it was probable that management would be unable to collect the contractually scheduled payments of principal or interest. When assessing impairment, management considered various factors, which included payment status, realizable value of collateral and the probability of collecting scheduled principal and interest payments when due. Loans and leases that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determined the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. For loans that indicated possible signs of impairment, which in most cases is based on the performance/non-performance status of the loan, an impairment analysis was conducted based on guidance provided by ASC 310-10. Impairment was measured by (i) the fair value of the collateral, if the loan was collateral-dependent, (ii) the present value of expected future cash flows discounted at the loan’s contractual effective interest rate, or (iii), less frequently, the loan’s obtainable market price. In addition to originating loans, the Corporation occasionally acquired loans through mergers or loan purchase transactions. Some of these acquired loans exhibited deteriorated credit quality that has occurred since origination and, as such, management did not expect to collect all contractual payments. Prior to January 1, 2020, accounting for these purchased credit-impaired (“PCI”) loans was done in accordance with ASC 310-30. The loans were recorded at fair value, reflecting the present value of the amounts expected to be collected. Income recognition on these loans was based on a reasonable expectation about the timing and amount of cash flows to be collected. Acquired loans deemed impaired and considered collateral-dependent, with the timing of the sale of loan collateral indeterminate, remained on nonaccrual status and had no accretable yield. On a regular basis, at least quarterly, PCI loans were assessed to determine if there had been any improvement or deterioration of the expected cash flows. If there had been improvement, an adjustment was made to increase the recognition of interest on the PCI loan, as the estimate of expected loss on the loan was reduced. Conversely, if there was deterioration in the expected cash flows of a PCI loan, a provision was recorded in connection with the loan.
Troubled Debt Restructurings (TDR's)	Troubled Debt Restructurings (“TDRs") A TDR occurs when a creditor, for economic or legal reasons related to a borrower’s financial difficulties, modifies the original terms of a loan or lease, or grants a concession to the borrower that it would not otherwise have granted. A concession may include an extension of repayment terms, a reduction in the interest rate, or the forgiveness of principal and/or accrued interest. If the debtor is experiencing financial difficulty and the creditor has granted a concession, the Corporation will make the necessary disclosures related to the TDR. In certain cases, a modification or concession may be made in an effort to retain a customer who is not experiencing financial difficulty. This type of modification is not considered a TDR.
Other Real Estate Owned (OREO)	Other Real Estate Owned (“OREO”) OREO consists of assets that the Corporation has acquired through foreclosure by either accepting a deed in lieu of foreclosure, or by taking possession of assets that were used as loan collateral. The Corporation reports OREO on the balance sheet as part of other assets, at the lower of cost or fair value less cost to sell, adjusted periodically based on current appraisals. Costs relating to the development or improvement of assets, as well as the costs required to obtain legal title to the property, are capitalized, while costs related to holding the property are charged to expense as incurred.
Other Investments and Equity Stocks Without a Readily Determinable Fair Value	Other Investments and Equity Stocks Without a Readily Determinable Fair Value
Premises and Equipment	Premises and Equipment Premises and equipment are stated at cost, less accumulated depreciation. Depreciation is calculated using the straight-line method based on estimated useful lives of the assets. Depreciation of leasehold improvements is calculated using the straight-line method over the lives of the related leases or useful lives of the related assets, whichever is shorter. Whenever events or changes in circumstances dictate, the Corporation tests its long-lived assets for impairment by determining whether the sum of the estimated undiscounted future cash flows attributable to a long-lived asset or asset group is less than the carrying amount of the long-lived asset or asset group. In the event the carrying amount of the long-lived asset or asset group is not recoverable, an impairment loss is measured as the amount by which the carrying amount of the long-lived asset or asset group exceeds its fair value. Maintenance, repairs and minor improvements are charged to noninterest expense in the Consolidated Statements of Income as incurred. For cloud computing arrangements in a service contract, the Corporation capitalizes costs for implementation activities in the application development stage depending on the nature of the costs. The costs incurred during the preliminary project and post-implementation stages are expensed as the activities are performed. The costs capitalized are expensed over the term of the hosting arrangement, which is the fixed, noncancelable term of the arrangement, plus any reasonably certain renewal periods. The capitalized implementation costs and amortization expense related to these costs are included in Other assets and Other operating expenses in the Consolidated Balance Sheets and Consolidated Statements of Income, respectively. As of December 31, 2020 and 2019, the Corporation had $6.9 million and $2.9 million of capitalized software implementation costs for cloud computing arrangements in a service contract. Amortization expense related to these capitalized implementation costs for the years ended December 31, 2020 and 2019 amounted to $618 thousand and $280 thousand, respectively.
Operating Leases	Operating Leases The Corporation’s operating leases consist of various retail branch locations and corporate offices. Management determines if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use assets (“ROU assets”) and operating lease liabilities in our Consolidated Balance Sheets. ROU assets and operating lease liabilities are recognized at the lease commencement date. Operating lease liabilities represent the present value of unpaid lease payments, including extension options that the Corporation is reasonably certain will be exercised. As the majority of our leases do not provide an implicit rate, we use our estimated incremental borrowing rate at the lease commencement date to determine the present value of unpaid lease payments. ROU assets represent our right to use underlying assets and are recorded as operating lease liabilities adjusted for prepayments or accrued lease payments, initial direct costs, lease incentives, and impairment of ROU assets.
Pension and Postretirement Benefit Plan	Pension and Postretirement Benefit Plan As of December 31, 2020, the Corporation had two non-qualified defined-benefit supplemental executive retirement plans and a postretirement benefit plan as discussed in Note 16, “Pension and Postretirement Benefit Plans,” in the accompanying Notes to the Consolidated Financial Statements in this Annual Report on Form 10-K. Net pension expense related to the defined-benefit consists of service cost, interest cost, return on plan assets, amortization of prior service cost, amortization of transition obligations and amortization of net actuarial gains and losses. As it relates to the costs associated with the post-retirement benefit plan, the costs are recognized as they are incurred.
Bank Owned Life Insurance (BOLI)	Bank Owned Life Insurance (“BOLI”) BOLI is recorded at its cash surrender value. Income from BOLI is tax-exempt and included as a component of noninterest income.
Derivative Financial Instruments	Derivative Financial Instruments The Corporation recognizes all derivative financial instruments on its balance sheet at fair value. Derivatives that are not hedges must be adjusted to fair value through income. The Corporation enters into interest rate swaps that allow commercial loan customers to effectively convert a variable-rate commercial loan agreement to a fixed-rate commercial loan agreement. Under these agreements, the Corporation originates variable-rate loans with customers in addition to interest rate swap agreements, which serve to effectively swap the customers’ variable-rate loans into fixed-rate loans. The Corporation then enters into corresponding swap agreements with swap dealer counterparties to economically hedge its exposure on the variable and fixed components of the customer agreements. The interest rate swaps with both the customers and third parties are not designated as hedges under FASB ASC 815 and are marked to market through earnings. As the interest rate swaps are structured to offset each other, changes to the underlying benchmark interest rates considered in the valuation of these instruments do not result in an impact to earnings; however, there may be fair value adjustments related to credit quality variations between counterparties, which may impact earnings as required by FASB ASC 820. In addition to interest rate swaps with customers, the Corporation may also enter into a risk participation agreement with another institution as a means to assume a portion of the credit risk associated with a loan structure which includes a derivative instrument, in exchange for fee income commensurate with the risk assumed. This type of derivative is referred to as an “RPA sold.” In addition, in an effort to reduce the credit risk associated with an interest rate swap agreement with a borrower for whom the Corporation has provided a loan structured with a derivative, the Corporation may purchase a risk participation agreement from an institution participating in the facility in exchange for a fee commensurate with the risk shared. This type of derivative is referred to as an “RPA purchased.” If a derivative has qualified as a hedge, depending on the nature of the hedge, changes in the fair value of the derivative are either offset against the change in fair value of the hedged assets, liabilities, or firm commitments through earnings, or recognized in other comprehensive income until the hedged item is recognized in earnings. The ineffective portion of a derivative’s change in fair value is recognized in earnings immediately. To determine fair value, management uses valuations obtained from a third party which utilizes a pricing model that incorporates assumptions about market conditions and risks that are current as of the reporting date. Management reviews, annually, the inputs utilized by its independent third-party valuation organization. The Corporation may use interest-rate swap agreements to modify the interest rate characteristics from variable to fixed, or fixed to variable, in order to reduce the impact of interest rate changes on future net interest income. If present, the Corporation accounts for its interest-rate swap contracts in cash flow hedging relationships by establishing and documenting the effectiveness of the instrument in offsetting the change in cash flows of assets or liabilities that are being hedged. To determine effectiveness, the management performs an analysis to identify if changes in fair value or cash flow of the derivative correlate to the equivalent changes in the forecasted interest receipts or payments related to a specified hedged item. Recorded amounts related to interest-rate swaps are included in other assets or liabilities. The change in fair value of the ineffective part of the
Accounting for Stock-Based Compensation	Accounting for Stock-Based Compensation Stock-based compensation cost is measured at the grant date, based on the fair value of the award and is recognized as an expense over the vesting period. All share-based payments, including grants of stock options, restricted stock awards and performance-based stock awards, are recognized as compensation expense in the statement of income at their fair value. The fair value of stock option grants is determined using the Black-Scholes pricing model which considers the expected life of the options, the volatility of our stock price, risk-free interest rate and annual dividend yield. The fair value of the restricted stock awards and performance-based awards whose performance is measured based on an internally produced metric is based on their closing price on the grant date, while the fair value of the performance-based stock awards which use an external measure, such as total stockholder return, is based on their grant-date market value adjusted for the likelihood of attaining certain pre-determined performance goals and is calculated by utilizing a Monte Carlo Simulation model.
Earnings per Common Share	Earnings per Common Share Basic earnings per common share excludes dilution and is computed by dividing income available to common shareholders by the weighted-average common shares outstanding during the period. Diluted earnings per common share takes into account the potential dilution that would occur if in-the-money stock options were exercised and converted into shares of common stock and restricted stock awards and performance-based stock awards were vested. Proceeds assumed to have been received on options exercises are assumed to be used to purchase shares of BMBC’s common stock at the average market price during the period, as required by the treasury stock method of accounting. The effects of stock options are excluded from the computation of diluted earnings per share in periods in which the effect would be antidilutive.
Income Taxes	Income Taxes Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carry-forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Net deferred tax assets are included within the other assets line item on the Consolidated Balance Sheets. The Corporation recognizes the benefit of a tax position only after determining that the Corporation would more-likely-than-not sustain the position following an examination. For tax positions meeting the more-likely-than-not threshold, the amount recognized in the Consolidated Financial Statements is the largest benefit that has a greater than 50 percent likelihood of being realized upon settlement with the relevant tax authority. Management applies these criteria to tax positions for which the statute of limitations remains open.
Revenue Recognition	Revenue Recognition With the exception of nonaccrual loans and leases, the Corporation recognizes all sources of income on the accrual method. Additional information relating to wealth management fee revenue recognition follows: The Corporation earns wealth management fee revenue from a variety of sources including fees from trust administration and other related fiduciary services, custody, investment management and advisory services, employee benefit account and IRA administration, estate settlement, tax service fees, shareholder service fees and brokerage. These fees are generally based on asset values and fluctuate with the market. Some revenue is not directly tied to asset value but is based on a flat fee for services provided. For many of our revenue sources, amounts are not received in the same accounting period in which they are earned. However, each source of wealth management fees is recorded on the accrual method of accounting. The most significant portion of the Corporation’s wealth management fees is derived from trust administration and other related services, custody, investment management and advisory services, and employee benefit account and IRA administration. These fees are generally billed monthly, in arrears, based on the market value of assets at the end of the previous billing period. A smaller number of customers are billed in a similar manner, but on a quarterly or annual basis, and some revenues are not based on market values. The balance of the Corporation’s wealth management fees includes estate settlement fees and tax service fees, which are recorded when the related service is performed, and asset management and brokerage fees on non-depository investment products, which are received one month in arrears, based on settled transactions, but are accrued in the month the settlement occurs. Included in other assets on the balance sheet is a receivable for wealth management fees that have been earned but not yet collected. Insurance revenue is primarily related to commissions earned on insurance policies and is recognized over the related policy coverage period.
Mortgage Servicing	Mortgage Servicing A portion of the residential mortgage loans originated by the Corporation is sold to third parties; however, the Corporation may retain the servicing rights related to these loans. A fee, usually based on a percentage of the outstanding principal balance of the loan, is received in return for these services. Gains on the sale of these loans are based on the specific identification method. An intangible asset, referred to as mortgage servicing rights (“MSRs") is recognized when a loan’s servicing rights are retained upon sale of a loan. MSRs are initially recorded at fair value based on a third-party valuation model which calculates the present value of estimated future servicing income. The model incorporates assumptions that market participants use in estimating future net servicing income, including estimates of prepayment speeds and discount rates. Mortgage loan prepayment speed is the annual rate at which borrowers are forecasted to repay their mortgage loan principal and is based on historical experience. The discount rate is used to determine the present value of future net servicing income. Another key assumption in the model is the required rate of return the market would expect for an asset with similar risk. These assumptions can, and generally will, change quarterly valuations as market conditions and interest rates change. Subsequent to the initial valuation, MSRs amortize to noninterest expense in proportion to, and over the period of, the estimated future net servicing life of the underlying loans. MSRs are evaluated quarterly for impairment based upon the fair value of the rights as compared to their carrying amount. Impairment is determined by stratifying the MSRs by predominant characteristics, such as interest rate and terms. Impairment is recognized through a valuation allowance for an individual grouping, to the extent that fair value is less than the carrying amount. If management later determines that all of a portion of the impairment no longer exists for a particular grouping, a reduction of the allowance may be recorded as an increase to income. Changes in valuation allowances are reported within Other operating expenses on the Consolidated Statement of Income. The fair value of servicing rights are subject to significant fluctuations as a result of changes in estimated and actual prepayment speeds and default rates and losses.
Goodwill and Intangible Assets	Goodwill and Intangible AssetsThe Corporation accounts for goodwill and intangible assets in accordance with ASC 350, “Intangibles – Goodwill and Other.” The amount of goodwill initially recorded is based on the fair value of the acquired entity at the time of acquisition. Management performs goodwill and intangible assets impairment testing annually, as of October 31, or when events occur or circumstances change that would more likely than not reduce the fair value of the acquisition or investment. Goodwill impairment is tested on a reporting unit level. The Corporation currently has three reporting units: Banking, Wealth Management and Insurance. As of December 31, 2020, the Insurance reporting unit did not meet the quantitative thresholds for separate disclosure as an operating segment, and is therefore reported as a component of the Wealth Management segment, based on its internal reporting structure. While the Insurance reporting unit did not meet the threshold for reporting as a separate operating segment for goodwill testing, the Insurance segment was tested for impairment. An operating segment is a component of an enterprise that engages in business activities from which it may earn revenues and incur expenses, whose operating results are regularly reviewed by the enterprise’s chief operating decision makers to make decisions about resources to be allocated to the segment and assess its performance, and for which discrete financial information is available.Management’s impairment testing methodology is consistent with the methodology prescribed in ASC 350. Management completes a goodwill impairment analysis at least on an annual basis, or more often if events and circumstances indicate that there may be impairment. Management also reviews other intangible assets with finite lives for impairment if events and circumstances indicate that the carrying value may not be recoverable.
Adopted Pronouncements and Pronouncements Not Effective	Adopted Pronouncements in 2020: FASB ASU 2016-13 (Topic 326), “Measurement of Credit Losses on Financial Instruments” On January 1, 2020, the Corporation adopted ASU 2016-13 (Topic 326), “Measurement of Credit Losses on Financial Instruments,” which replaces the incurred loss methodology with an expected loss methodology that is referred to as the current expected credit loss (or CECL) methodology. This standard eliminates the Provision for Loan and Lease Losses and Allowance for Loan and Lease Losses line items and establishes the Provision for Credit Losses (“PCL”) and ACL line items. The measurement of expected credit losses under the CECL methodology is applicable to financial assets measured at amortized cost, including loan receivables and held-to-maturity debt securities. It also applies to OBS credit exposures not accounted for as insurance (loan commitments, standby letters of credit, financial guarantees, and other similar instruments) and net investments in leases recognized by a lessor in accordance with Topic 842 on leases. In addition, ASC 326 made changes to the accounting for available for sale debt securities. One such change is to require credit losses to be presented as an allowance rather than as a write-down on available-for-sale debt securities management does not intend to sell or believes that it is more likely than not they will be required to sell. The Corporation adopted ASC 326 using the modified retrospective approach method for all financial assets measured at amortized cost and OBS credit exposures. Results for reporting periods beginning after January 1, 2020 are presented under ASC 326 while prior period amounts continue to be reported in accordance with previously applicable GAAP. In conjunction with the adoption of CECL, the Corporation has revised its segmentation to align with the methodology applied in determining the ACL for loans and leases under CECL, which is based on federal call report codes which classify loans based on the primary collateral supporting the loan. Segmentation prior to the adoption of CECL was based on product type or purpose. As such, certain reclassifications were made to conform prior-period amounts to current period presentation. Upon adoption, the Corporation's total ACL increased by $4.0 million, or 17.5%, which included an increase in ACL on loans and leases of $3.2 million and an increase in the reserve for OBS exposures, which is included within Other Liabilities on the Consolidated Balance Sheet, of $821 thousand. The increase in the total ACL resulted in a $2.8 million decrease to retained earnings, net of deferred taxes. The overall change in total ACL upon adoption was primarily due to the move to a life of loan reserve estimate as well as methodology changes required under CECL. The Corporation adopted CECL using the prospective transition approach for financial assets purchased with credit deterioration (“PCD”) that were previously classified as purchased credit impaired (“PCI”) and accounted for under ASC 310-30. In accordance with the standard, management did not reassess whether PCI assets met the criteria of PCD assets as of the date of adoption. On January 1, 2020, the amortized cost basis of the PCD assets were adjusted to reflect the addition of $481 thousand of the allowance for credit losses. The remaining noncredit discount (based on the adjusted amortized cost basis) will be accreted into interest income at the effective interest rate as of January 1, 2020.

Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. ASU 2017-04 became effective for the Corporation on January 1, 2020, and will follow such guidance in connection with our next annual impairment testing, or prior to that if any such change constitutes a triggering event outside of the quarter from when the annual goodwill impairment test is performed. Management does not expect the adoption of this ASU to have a material impact on our Consolidated Financial Statements and related disclosures. FASB ASU 2018-13, “Fair Value Measurement Disclosure Framework” Issued in August 2018, ASU 2018-13 modifies, adds and removes certain disclosures aimed to improve the overall usefulness of the disclosure requirements for fair value measurements. The guidance became effective for the Corporation on January 1, 2020 and the adoption of this ASU did not have a material impact on our Consolidated Financial Statements and related disclosures. Pronouncements Not Effective as of December 31, 2020: FASB ASU 2018-14 (Topic 715), "Compensation-Retirement Benefits - Defined Benefit Plans-General" Issued in August 2018, the ASU 2018-14, modifies, adds and removes certain disclosures aimed to improve the overall usefulness of the disclosure requirements to financial statement users. The guidance is effective for annual periods beginning after December 15, 2020. Early adoption is permitted. Use of the retrospective method is required. Management does not expect the adoption of this ASU to have a material impact on our Consolidated Financial Statements and related disclosures. FASB ASU 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes” Issued in December 2019, ASU 2019-12 adds new guidance to simplify accounting for income taxes, changes the accounting for certain income tax transactions and makes minor improvements to the codification. The guidance is effective for annual periods beginning after December 15, 2020. Early adoption is permitted. Management does not expect the adoption of this ASU to have a material impact on our Consolidated Financial Statements and related disclosures. FASB ASU No. 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting” Issued in March 2020, ASU No. 2020-04 provides optional guidance to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. Specifically, the guidance permits an entity, when certain criteria are met, to consider amendments to contracts made to comply with reference rate reform to meet the definition of a modification under GAAP. It further allows hedge accounting to be maintained and a one-time transfer or sale of qualifying held-to-maturity securities. The expedients and exceptions provided by the amendments are permitted to be adopted any time through December 31, 2022 and do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for certain optional expedients elected for certain hedging relationships existing as of December 31, 2022. The Corporation will apply the guidance to any contracts modifications made due to reference rate reform.
