Preparation of Financial Statements [Abstract]
Preparation of Financial Statements	1. Preparation of Financial Statements The condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and note disclosures normally included in annual financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted pursuant to those rules and regulations, although we believe that the disclosures made are adequate to make the information not misleading. The unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes for the year ended December 31, 2020 included in our Annual Report on Form 10-K. In our opinion, the accompanying unaudited condensed consolidated financial statements contain all the adjustments necessary to present fairly our consolidated financial condition as of March 31, 2021 and December 31, 2020, and the results of operations for the three month periods ended March 31, 2021 and 2020. The results of operations for the three month period ended March 31, 2021, are not necessarily indicative of the results to be expected for the full year. Certain reclassifications have been made in the prior period condensed consolidated financial statements to conform to the current period presentation. Our critical accounting policies include the determination of the allowance for credit losses (“ACL”) and the valuation of capitalized mortgage loan servicing rights. Refer to our 2020 Annual Report on Form 10-K for a disclosure of our accounting policies.

New Accounting Standards

New Accounting Standards [Abstract]
New Accounting Standards	2. New Accounting Standards In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-13, ‘‘Financial Instruments — Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments’’. This ASU significantly changes how entities will measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. This ASU: • Replaces the existing incurred loss impairment guidance and establishes a single allowance framework for financial assets carried at amortized cost, which will reflect our estimate of credit losses over the full remaining expected life of the financial assets and will consider expected future changes in macroeconomic conditions. • Eliminates existing guidance for purchase credit impaired (‘‘PCI’’) loans, and requires recognition of the nonaccretable difference as an increase to the allowance for expected credit losses on financial assets purchased with more than insignificant credit deterioration since origination, which will be offset by an increase in the recorded investment of the related loans. • Requires inclusion of expected recoveries, limited to the cumulative amount of prior write-offs, when estimating the ACL for in scope financial assets (including collateral dependent assets). • Amends existing impairment guidance for securities available for sale to incorporate an allowance, which will allow for reversals of credit impairments in the event that the credit of an issuer improves. Credit losses on securities available for sale are limited to the amount of the decline in fair value regardless of what the credit loss model would show for impairment. • Generally requires a cumulative-effect adjustment to retained earnings as of the beginning of the reporting period of adoption. We began evaluating this ASU in 2016 and established a company-wide, cross-discipline governance structure, which provides implementation oversight. We continued to test and refine our current expected credit loss (“CECL”) models that satisfied the requirements of this ASU. Oversight and testing, as well as efforts to meet expanded disclosure requirements, extended through the end of 2020. We currently estimate losses over approximately a forecast period using external economic forecast sources, including the Federal Open Market Committee median economic projections, and then revert to longer term historical loss experience to estimate losses over more extended periods. We were originally required to adopt this ASU on January 1, 2020 but section 4014 of the Coronavirus Aid, Relief, and Economic Security (‘‘CARES’’) Act allowed for temporary relief from applying this ASU. Under the amended CARES Act we were allowed to delay the adoption of this ASU until the earlier of the termination of the national emergency that was declared on March 13, 2020, or January 1, 2022. Early adoption was also allowed on either January 1, 2020 or January 1, 2021. As such, we chose to delay the adoption of this ASU during 2020 and adopted this ASU on January 1, 2021. Results for the reporting periods after January 1, 2021 are presented under this new ASU while prior period amounts continue to be reported in accordance with previously applicable accounting guidance We adopted this ASU using the modified retrospective method for all financial assets measured at amortized cost and unfunded lending commitments. As of January 1, 2021 we increased the ACL by $ million which was primarily driven by the longer contractual maturities of our mortgage and consumer installment loan portfolio segments. In addition, we increased the allowance for losses related to unfunded loan commitments by $ million. The ultimate impact of adopting this ASU, and at each subsequent reporting period, is highly dependent on credit quality, economic forecasts and conditions, composition of our loan portfolios and securities available for sale, along with other management judgments. As of January 1, 2021, we recorded a cumulative-effect adjustment of $ million to decrease retained earnings. Based on our evaluation of securities available for sale, we did not record an ACL on these securities under this ASU. We adopted this ASU using the prospective transition approach for financial assets purchased with credit deterioration (“PCD”) that were previously classified as PCI and accounted for under accounting standards codification (“ASC”) 310-30. In accordance with this ASU, we did not reassess whether PCI assets met the definition of PCD assets as of the date of adoption. On January 1, 2021, the amortized cost basis of the PCD assets were adjusted to reflect the addition of $ million to the ACL for loans. The remaining noncredit discount in the amount of $ million (based on the adjusted amortized cost basis) will be accreted into interest income at the effective interest rate as of January 1, 2021. The impact of the adoption of this ASU follows: As Reported Under ASU 2016-13 Pre-ASU 2016-13 Adoption Impact of ASU 2016-13 Assets Loans Commercial $ 1,242,510 $ 1,242,415 $ 95 Mortgage 1,015,944 1,015,926 18 Installment 475,358 475,337 21 Total loans 2,733,812 2,733,678 134 Allowance for credit losses (47,137 ) (35,429 ) (11,708 ) Net loans $ 2,686,675 $ 2,698,249 $ (11,574 ) Deferred tax assets (1) $ 65,196 $ 62,456 $ 2,740 Total Assets $ 4,195,179 $ 4,204,013 $ (8,834 ) Liabilities and shareholders's equity Allowance for credit losses on unfunded lending commitments (2) $ 3,274 $ 1,805 $ 1,469 Total liabilities $ 3,815,960 $ 3,814,491 $ 1,469 Retained earnings $ 29,842 $ 40,145 $ (10,303 ) Total shareholders' equity $ 379,219 $ 389,522 $ (10,303 ) Total liabilities and shareholders' equity $ 4,195,179 $ 4,204,013 $ (8,834 ) (1) Included in Accrued income and other assets in our Condensed Consolidated Statements of Financial Condition. (2) Included in Accrued expenses and other liabilities in our Condensed Consolidated Statements of Financial Condition. In March 2020, the FASB issued ASU 2020-04, ‘‘Reference Rate Reform (Topic 848), Facilitation of the Effects of Reference Rate Reform on Financial Reporting’’. This new ASU provides temporary optional expedients and exceptions to GAAP guidance on contract modifications and hedge accounting to ease the financial reporting burdens of the expected market transition from LIBOR and other interbank offered rates to alternative reference rates. Entities can elect not to apply certain modification accounting requirements to contracts affected by reference rate reform, if certain criteria are met. Entities that make such elections would not have to remeasure contracts at the modification date or reassess a previous accounting determination. Entities can elect various optional expedients that would allow them to continue applying hedge accounting for hedging relationships affected by reference rate reform, if certain criteria are met. This amended guidance and our ability to elect its temporary optional expedients and exceptions are effective for us as of March 12, 2020 through December 31, 2022.

For securities available for sale in an unrealized loss position, we assess whether we intend to sell, or it is more likely than not that we 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 securities available for sale that do not meet this criteria, we evaluate whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, we consider the extent to which fair value is less than amortized cost, adverse conditions specifically related to the security and the issuer and the impact of changes in market interest rates on the market value of the security, among other factors. If this assessment indicates that a credit loss exists, we compare the present value of cash flows expected to be collected from the security with 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 for the security, a credit loss exists and an ACL is recorded, limited to the amount that the fair value of the security is less than its amortized cost basis. Any impairment that has not been recorded through an ACL is recognized in other comprehensive income, net of applicable taxes. ACL for securities available for sale was needed at March Accrued interest receivable on securities available for sale totaled at March and is excluded from the estimate of credit losses. U.S. agency, U.S. agency residential mortgage-backed and U.S. agency commercial mortgage-backed securities — at March 31, 2021, we had U.S. agency, U.S. agency residential mortgage-backed and U.S. agency commercial mortgage-backed securities whose fair value is less than amortized cost. These securities are either explicitly or implicitly guaranteed by the U.S. government, are highly rated by major credit rating agencies, and have a long history of no credit losses. The unrealized losses are largely attributed to widening spreads to Treasury bonds and/or an increase in interest rates since acquisition. Private label mortgage backed, other asset backed and corporate securities — at March 31, 2021, we had private label mortgage backed, other asset backed and corporate securities whose fair value is less than amortized cost. The unrealized losses are primarily due to credit spread widening and/or an increase in interest rates since acquisition. Obligations of states and political subdivisions — at March 31, 2021, we had municipal securities whose fair value is less than amortized cost. The unrealized losses are primarily due to an increase in interest rates since acquisition. Trust preferred securities — at March 31, 2021, we had trust preferred securities whose fair value is less than amortized cost. Both of our trust preferred securities are single issue securities issued by a trust subsidiary of a bank holding company. The pricing of trust preferred securities has suffered from credit spread widening. of the securities is rated by a major rating agency as investment grade while the other is non-rated. The non-rated issue is a relatively small bank and was never rated. The issuer of this non-rated trust preferred security, which had a total amortized cost of $ million and total fair value of $ million as of March 31, 2021, continues to have satisfactory credit metrics and make interest payments. At March 31, 2021 management does not intend to liquidate any of the securities discussed above and it is more likely than not that we will not be required to sell these securities prior to recovery of these unrealized losses. We recorded no credit related charges in our Condensed Consolidated Statements of Operations related to securities available for sale during the three month periods ended March 31, 2021 and 2020, respectively.

Loans [Abstract]
Loans	4. Loans We estimate the ACL based on relevant available information from both internal and external sources, including historical loss trends, current conditions and forecasts, specific analysis of individual loans, and a review of other relevant and appropriate factors. The allowance process is designed to provide for expected future losses based on our reasonable and supportable (“R&S”) forecast as of the reporting date. Our ACL process is administered by our Risk Management group utilizing a third party software solution, with significant input and ultimate approval from our Executive Enterprise Risk Committee. Further, we have established a CECL Forecast Committee, which includes a cross discipline structure with membership from Executive Management, Risk Management, and Accounting, which approves ACL model assumptions each quarter. Our ACL is comprised of three principal elements: (i) specific analysis of individual loans identified during the review of the loan portfolio, (ii) pooled analysis of loans with similar risk characteristics based on historical experience, adjusted for current conditions, R&S forecasts, and expected prepayments, and (iii) additional allowances based on subjective factors, including local and general economic business factors and trends, portfolio concentrations and changes in the size and/or the general terms of the loan portfolios. The first ACL element (specific allocations) includes loans that do not share similar risk characteristics and are evaluated on an individual basis. We will typically evaluate on an individual basis loans that are on nonaccrual, commercial loans designated as a TDR, or mortgage and installment TDR loans with a rate concession. When we determine that foreclosure is probable or when repayment is expected to be provided substantially through the operation or sale of underlying collateral, expected credit losses are based on the fair value of the collateral at the reporting date, adjusted for selling costs. For loans evaluated on an individual basis that are not determined to be collateral dependent, a discounted cash flow analysis is performed to determine expected credit losses. The second ACL element (pooled analysis) includes loans with similar risk characteristics, which are broken down by segment, class, and risk metric. The Bank’s primary segments of commercial, mortgage, and installment loans are further classified by other relevant attributes, such as collateral type, lien position, occupancy status, amortization method, and balance size. Commercial classes are additionally segmented by risk rating, and mortgage and installment loan classes by credit score tier, which are updated at least semi-annually. We utilize a discounted cash flow (“DCF”) model to estimate expected future losses for pooled loans. Expected future cash flows are developed from payment schedules over the contractual term, adjusted for forecasted default (probability of default), loss, and prepayment assumptions. We are not required to develop forecasts over the full contractual term of the financial asset or group of financial assets. Rather, for periods beyond which the entity is able to make or obtain R&S forecasts of expected credit losses, we revert to the long term average on a straight line or immediate basis, as determined by the CECL Forecast Committee, and which may vary depending on the economic outlook and uncertainty. The DCF model for the mortgage and installment pooled loan segments includes using probability of default (“PD”) assumptions that are derived through regression analysis with forecasted US unemployment levels by credit score tier. We review the Bloomberg composite forecast of approximately 50 analysts as well as the FOMC projections in setting the unemployment forecast for the R&S period. The current ACL utilizes a one year R&S forecast followed by immediate reversion to the 30 year average unemployment rate. PD assumptions for the remaining segments are based primarily on historical rates by risk metric as defaults were not strongly correlated with any economic indicator. Loss given default (“LGD”) assumptions for the mortgage loan segment are based on a two year forecast followed by a two year straight line reversion period to the longer term average, while LGD rates for the remaining segments are the historical average for the entire period. Prepayment assumptions represent the two year average rates per segment as calculated through the Bank’s Asset and Liability Management program. Pooled reserves for the commercial loan segment are calculated using the DCF model with assumptions generally based on historical averages by class and risk rating. Effective risk rating practices allow for strong predictability of defaults and losses over the portfolio’s expected shorter duration, relative to mortgage and installment loans. Our rating system is similar to those employed by state and federal banking regulators. The third ACL element (additional allocations based on subjective factors) is based on factors that cannot be associated with a specific credit or loan category and reflects our attempt to ensure that the overall ACL appropriately reflects a margin for the imprecision necessarily inherent in the estimates of expected credit losses. We adjust our quantitative model for certain qualitative factors to reflect the extent to which management expects current conditions and R&S forecasts to differ from the conditions that existed for the period over which historical information was evaluated. The qualitative framework reflects changes related to relevant data, such as changes in asset quality trends, portfolio growth and composition, national and local economic factors, credit policy and administration and other factors not considered in the base quantitative model. We utilize a survey completed by business unit management throughout the bank, as well as discussion with the CECL Forecast Committee to establish reserves under the qualitative framework. The current period’s ACL further recognizes inherent risk related to the ongoing COVID-19 pandemic; specifically to the volume of loans on forbearance, commercial loans in high risk industries, and mortgage and installment borrowers with occupations in those high risk industries. Identified high risk industries include: food service, hospitality, entertainment, retail, investment real estate, assisted living, and non-owner occupied office.

During the three months ended March 31, 2021 and 2020, the terms of certain loans were modified as TDRs. The modification of the terms of such loans generally included one or a combination of the following: a reduction of the stated interest rate of the loan; an extension of the maturity date at a stated rate of interest lower than the current market rate for a new loan with similar risk; or a permanent reduction of the recorded investment in the loan. Modifications involving a reduction of the stated interest rate of the loan have generally been for periods ranging from 9 months to 36 months but have extended to as much as 480 months in certain circumstances. Modifications involving an extension of the maturity date have generally been for periods ranging from 1 month to 60 months but have extended to as much as 230 months in certain circumstances. Loans that have been classified as TDRs during the three-month periods ended March 31 follow: Number of Contracts Pre-modification Balance Post-modification Balance (Dollars in thousands) 2021 Commercial Commercial and industrial - $ - $ - Commercial real estate - - - Mortgage 1-4 family owner occupied - jumbo - - - 1-4 family owner occupied - non-jumbo - - - 1-4 family non-owner occupied - - - 1-4 family - 2nd lien - - - Resort lending - - - Installment Boat lending - - - Recreational vehicle lending - - - Other - - - Total - $ - $ - 2020 Commercial Commercial and industrial 1 $ 99 $ 99 Commercial real estate 3 1,177 1,177 Mortgage 1-4 family owner occupied - jumbo - - - 1-4 family owner occupied - non-jumbo 1 49 50 1-4 family non-owner occupied 1 59 62 1-4 family - 2nd lien - - - Resort lending - - - Installment Boat lending - - - Recreational vehicle lending - - - Other 1 33 34 Total 7 $ 1,417 $ 1,422 The TDRs described above for 2021 had impact on the There were no TDRs that subsequently defaulted within twelve months following the modification during the three months periods ended March 31, 2021 and 2020. A loan is considered to be in payment default generally once it is 90 days contractually past due under the modified terms. In order to determine whether a borrower is experiencing financial difficulty, we perform an evaluation of the probability that the borrower will be in payment default on any of its debt in the foreseeable future without the modification. This evaluation is performed under our internal underwriting policy. Non-TDR Loan Modifications and Paycheck Protection Program (“PPP”) due to COVID- 19 - On March the federal banking agencies issued an “Interagency Statement on Loan Modifications and Reporting for Financial Institutions Working with Customers Affected by the Coronavirus”. This guidance encourages financial institutions to work prudently with borrowers that may be unable to meet their contractual obligations because of the effects of COVID- The guidance goes on to explain that in consultation with the Financial Accounting Standards Board staff that the federal banking agencies conclude that short-term modifications (e.g. months or less) made on a good faith basis to borrowers who were current (less than days past due) as of the implementation date of a relief program are not TDRs. . Section of the CARES Act also addressed COVID- related modifications and specified that COVID- related modifications on loans that were current (less than days past due) as of December are not TDRs.

The CARES Act also included an initial $349 billion loan program administered through the U.S. Small Business Administration (‘‘SBA’’) referred to as the PPP. Under the PPP, small businesses and other entities and individuals can apply for loans from existing SBA lenders and other approved regulated lenders that enroll in the program, subject to numerous limitations and eligibility criteria. We are participating as a lender in the PPP. The PPP opened on April 3, 2020 intending to provide American small businesses with eight weeks of cash-flow assistance through 100 percent federally guaranteed loans through the SBA. In late April 2020 the Paycheck Protection Program and Health Care Enhancement Act, added another $310 billion in funding while the Paycheck Protection Program Flexibility Act made certain changes to the program, by allowing for more time to spend the funds, and making it easier to get a loan fully forgiven. The PPP initially closed on August 8, 2020 (“Round 1”). On December 27, 2020, the Economic Aid to Hard-Hit Small Businesses, Nonprofits, and Venues Act (‘‘Economic Aid Act’’) was signed into law which allocates an additional $284 billion in funding for the PPP (“Round 2”). The Economic Aid Act reopens the PPP through March 31, 2021 with generally the same terms and conditions as originally enacted under the CARES Act while clarifying eligibility and ineligibility for certain entities and expanding the permitted uses of PPP funds. In addition, the Economic Aid Act simplifies the loan forgiveness process for PPP loans of $150,000 or less. The Economic Aid Act also establishes second draw loans for entities that have already used the initial PPP funds, subject to numerous limitations and eligibility criteria. PPP Round 2 loans are eligible for forgiveness similar to Round 1 PPP loans, subject to limitations set forth in the Economic Aid Act. The following table summarizes PPP loans outstanding: Paycheck Protection Program As of March 31, 2021 As of December 31, 2020 Amount (#) Amount Amount (#) Amount (Dollars in thousands) (Dollars in thousands) Closed and outstanding - Round 1 loans 698 $ 105,934 1,483 $ 169,782 Closed and outstanding - Round 2 loans 1,250 128,240 - - Total closed and outstanding 1,948 $ 234,174 1,483 $ 169,782 Unaccreted net fees remaining at period end $ 6,816 $ 3,216 PPP loans are included in the commercial and industrial class of the commercial loan portfolio segment. As these loans are 100% guaranteed through the SBA the allowance for credit losses recorded on these loans is zero. Interest and fees on loans in our consolidated statement of operations includes $2.1 million during the three month period ended March 31, 2021, related to the accretion of net loan fees on PPP loans. No such accretion is included in the comparable prior year period. Credit Quality Indicators For commercial loans, we use a loan rating system that is similar to those employed by state and federal banking regulators. Loans are graded on a scale of 1 to 12. A description of the general characteristics of the ratings follows: Rating 1 through 6 Rating 7 and 8 Rating 9 Rating 10 and 11 : These loans are generally referred to as our ‘‘substandard - non-accrual’’ and ‘‘doubtful’’ commercial credits. Our doubtful rating includes a sub classification for a loss rate other than 50% (which is the standard doubtful loss rate). These ratings include loans to borrowers with weaknesses that make collection of the loan in full, on the basis of current facts, conditions and values at best questionable and at worst improbable. All of these loans are placed in non-accrual. Rating 12 The following table summarizes loan ratings by loan class for our commercial portfolio loan segment as of March 31, 2021: Commercial Term Loans Amortized Cost Basis by Origination Year Revolving Loans Amortized 2021 2020 2019 2018 2017 Prior Cost Basis Total (In thousands) March 31, 2021 Commercial and industrial Non-watch (1-6) $ 142,043 $ 206,986 $ 67,404 $ 48,651 $ 59,051 $ 47,122 $ 130,580 $ 701,837 Watch (7-8) 666 5,458 1,846 3,736 704 4,020 6,731 23,161 Substandard Accrual (9) -

Derivative Financial Instruments [Abstract]
Derivative Financial Instruments	6. Derivative Financial Instruments We are required to record derivatives on our Condensed Consolidated Statements of Financial Condition as assets and liabilities measured at their fair value. The accounting for increases and decreases in the value of derivatives depends upon the use of derivatives and whether the derivatives qualify for hedge accounting. Our derivative financial instruments according to the type of hedge in which they are designated follows: March 31, 2021 Notional Amount Average Maturity (years) Fair Value (Dollars in thousands) Fair value hedge designation Pay-fixed interest rate swap agreements - commercial $ 7,005 8.1 $ (423 ) Pay-fixed interest rate swap agreements - securities available for sale 148,895 6.6 4,887 Total $ 155,900 6.7 $ 4,464 No hedge designation Rate-lock mortgage loan commitments $ 187,834 0.1 $ 3,198 Mandatory commitments to sell mortgage loans 165,609 0.1 896 Pay-fixed interest rate swap agreements - commercial 149,328 4.3 (6,425 ) Pay-variable interest rate swap agreements - commercial 149,328 4.3 6,425 Pay-fixed interest rate swap agreements 25,000 0.3 (177 ) Interest rate cap agreements 135,000 1.5 20 Purchased options 2,193 0.4 60 Written options 2,193 0.4 (60 ) Total $ 816,485 1.9 $ 3,937 December 31, 2020 Notional Amount Average Maturity (years) Fair Value (Dollars in thousands) Fair value hedge designation Pay-fixed interest rate swap agreements - commercial $ 7,088 8.4 $ (776 ) Pay-fixed interest rate swap agreements - securities available for sale 41,950 7.1 15 Total $ 49,038 7.3 $ (761 ) No hedge designation Rate-lock mortgage loan commitments $ 168,816 0.1 $ 7,020 Mandatory commitments to sell mortgage loans 186,092 0.1 (941 ) Pay-fixed interest rate swap agreements - commercial 147,456 4.5 (9,700 ) Pay-variable interest rate swap agreements - commercial 147,456 4.5 9,700 Pay-fixed interest rate swap agreements 25,000 0.6 (295 ) Interest rate cap agreements 135,000 1.8 5 Purchased options 2,908 0.5 42 Written options 2,848 0.5 (42 ) Total $ 815,576 2.0 $ 5,789 We have used variable-rate and short-term fixed-rate (less than 12 months) debt obligations to fund a portion of our Condensed Consolidated Statements of Financial Condition, which exposed us to variability in interest rates. To meet our asset/liability management objectives, we may periodically enter into derivative financial instruments to mitigate exposure to fluctuations in cash flows resulting from changes in interest rates (“Cash Flow Hedges”). Cash Flow Hedges had included certain pay-fixed interest rate swap and interest rate cap agreements. Pay-fixed interest rate swap agreements convert the variable-rate cash flows on debt obligations to fixed-rates. Under interest-rate cap agreements, we will receive cash if interest rates rise above a predetermined level. As a result, we effectively have variable-rate debt with an established maximum rate. We paid an upfront premium on interest rate caps which was recognized in earnings in the same period in which the hedged item affected earnings. During the first and third quarters of 2020 we transferred all of our Cash Flow Hedge interest rate cap and pay-fixed interest rate swap agreements, respectively to a no hedge designation. The $ million and $ million unrealized loss on our Cash Flow Hedge interest rate cap and pay-fixed interest rate swap agreements, respectively, which were included as a component of accumulated other comprehensive income at the time of the transfers, were being reclassified into earnings over the remaining life of the interest rate cap agreements and pay-fixed interest rate swap agreements. In the fourth quarter of 2020 it became probable that the forecasted transactions being hedged by these interest rate cap and pay-fixed interest rate swap agreements would not occur by the end of the originally specified time period. As a result, all remaining unrealized losses included as a component of accumulated other comprehensive income were reclassified into earnings at that time. The interest rate cap and pay-fixed interest rate swap agreements are now classified as a no hedge designation at March 31, 2021 and any changes in fair value since the transfers to the no hedge designation are recorded in earnings. We have entered into a pay-fixed interest rate swap to protect a portion of the fair value of a certain fixed rate commercial loan (‘‘Fair Value Hedge – Commercial Loan’’). As a result, changes in the fair value of the pay-fixed interest rate swap is expected to offset changes in the fair value of the fixed rate commercial loan due to fluctuations in interest rates. We record the fair value of Fair Value Hedge – Commercial Loan in accrued income and other assets and accrued expenses and other liabilities on our Condensed Consolidated Statements of Financial Condition. The hedged item (fixed rate commercial loan) is also recorded at fair value which offsets the adjustment to the Fair Value Hedge – Commercial Loan. On an ongoing basis, we adjust our Condensed Consolidated Statements of Financial Condition to reflect the then current fair value of both the Fair Value Hedge – Commercial Loan and the hedged item. The related gains or losses are reported in interest income – interest and fees on loans in our Condensed Consolidated Statements of Operations. We have entered into pay-fixed interest rate swaps to protect a portion of the fair value of certain securities available for sale (‘‘Fair Value Hedge – AFS Securities’’). As a result, the change in the fair value of the pay-fixed interest rate swaps is expected to offset a portion of the change in the fair value of the fixed rate securities available for sale due to fluctuations in interest rates. We record the fair value of Fair Value Hedge – AFS Securities in accrued income and other assets and accrued expenses and other liabilities on our Condensed Consolidated Statements of Financial Condition. The hedged items (fixed rate securities available for sale) are also recorded at fair value which offsets the adjustment to the Fair Value Hedge – AFS Securities. On an ongoing basis, we adjust our Condensed Consolidated Statements of Financial Condition to reflect the then current fair value of both the Fair Value Hedge – AFS Securities and the hedged item. The related gains or losses are reported in interest income – interest on securities available for sale – tax-exempt in our Condensed Consolidated Statements of Operations. Certain financial derivative instruments have not been designated as hedges. The fair value of these derivative financial instruments has been recorded on our Condensed Consolidated Statements of Financial Condition and is adjusted on an ongoing basis to reflect their then current fair value. The changes in fair value of derivative financial instruments not designated as hedges are recognized in our Condensed Consolidated Statements of Operations. In the ordinary course of business, we enter into rate-lock mortgage loan commitments with customers (“Rate-Lock Commitments”). These commitments expose us to interest rate risk. We also enter into mandatory commitments to sell mortgage loans (“Mandatory Commitments”) to reduce the impact of price fluctuations of mortgage loans held for sale and Rate-Lock Commitments. Mandatory Commitments help protect our loan sale profit margin from fluctuations in interest rates. The changes in the fair value of Rate-Lock Commitments and Mandatory Commitments are recognized currently as part of net gains on mortgage loans in our Condensed Consolidated Statements of Operations. We obtain market prices on Mandatory Commitments and Rate-Lock Commitments. Net gains on mortgage loans, as well as net income may be more volatile as a result of these derivative instruments, which are not designated as hedges. In prior periods we offered to our deposit customers an equity linked time deposit product (“Altitude CD”). The Altitude CD was a time deposit that provides the customer a guaranteed return of principal at maturity plus a potential equity return (a written option), while we receive a like stream of funds based on the equity return (a purchased option). The written and purchased options will generally move in opposite directions resulting in little or no net impact on our Condensed Consolidated Statements of Operations. All of the written and purchased options in the table above relate to this Altitude CD product. We have a program that allows commercial loan customers to lock in a fixed rate for a longer period of time than we would normally offer for interest rate risk reasons. We will enter into a variable rate commercial loan and an interest rate swap agreement with a customer and then enter into an offsetting interest rate swap agreement with an unrelated party. The interest rate swap agreement fair values will generally move in opposite directions resulting in little or no net impact on our Condensed Consolidated Statements of Operations. All of the interest rate swap agreements noted as commercial in the table above with no hedge designation relate to this program.

Share Based Compensation [Abstract]
Share Based Compensation	8. Share Based Compensation We maintain share based payment plans that include a non-employee director stock purchase plan and a long-term incentive plan that permits the issuance of share based compensation, including stock options and non-vested share awards. The long-term incentive plan, which is shareholder approved, permits the grant of additional share based awards for up to 0.4 million shares of common stock as of March 31, 2021. The non-employee director stock purchase plan permits the issuance of additional share based payments for up to 0.1 million shares of common stock as of March 31, 2021. Share based awards and payments are measured at fair value at the date of grant and are expensed over the requisite service period. Common shares issued upon exercise of stock options come from currently authorized but unissued shares. A summary of restricted stock and performance stock units (“PSU”) granted pursuant to our long-term incentive plan follows: Three Months Ended March 31, 2021 2020 Restricted stock 75,584 52,996 PSU 23,981 20,897 The shares of restricted stock and PSUs shown in the above table cliff vest after a period of three years. The performance feature of the PSUs is based on a comparison of our total shareholder return over the three year period starting on the grant date to the total shareholder return over that period for an index of our banking peers. Our directors may elect to receive all or a portion of their cash retainer fees in the form of common stock (either on a current basis or on a deferred basis) pursuant to the non-employee director stock purchase plan referenced above. Shares equal in value to that portion of each director’s fees that he or she has elected to receive in stock on a current basis are issued each quarter and vest immediately. Shares issued on a deferred basis are credited at the rate of 90% of the current fair value of our common stock and vest immediately. During the three month periods ended March 31, 2021 and 2020 we issued 0.005 million and 0.004 million shares, respectively and expensed their value during those same periods. Total compensation expense recognized for grants pursuant to our long-term incentive plan was $0.3 million and $0.5 million during the three month periods ended March 31, 2021 and 2020, respectively. The corresponding tax benefit relating to this expense was $0.1 million for each period. Total expense recognized for non-employee director share based payments was $0.09 million during both three month periods ended March 31, 2021 and 2020. The corresponding tax benefit relating to this expense was $0.02 million during each period. At March 31, 2021, the total expected compensation cost related to non-vested restricted stock and PSUs not yet recognized was $3.2 million. The weighted-average period over which this amount will be recognized is 2.3 years.

Income Tax [Abstract]
Income Tax	9. Income Tax Income tax expense was $5.1 million and $0.9 million during the three month periods ended March 31, 2021 and 2020, respectively. Our actual federal income tax expense is different than the amount computed by applying our statutory income tax rate to our income before income tax primarily due to tax-exempt interest income and tax-exempt income from the increase in the cash surrender value on life insurance. In addition, the first quarters of 2021 and 2020 include reductions of $0.1 million and $0.2 million of income tax expense related to impact of the excess value of stock awards that vested and stock options that were exercised as compared to the initial fair values that were expensed. W e assess whether a valuation allowance should be established against our deferred tax assets based on the consideration of all available evidence using a “more likely than not” standard. The ultimate realization of this asset is primarily based on generating future income. We concluded at and that the realization of substantially all of our deferred tax assets continues to be more likely than not At both March 31, 2021 and December 31, 2020 we had approximately , of gross unrecognized tax benefits. We do not expect the total amount of unrecognized tax benefits to significantly increase or decrease during the balance of 2021

Regulatory Matters [Abstract]
Regulatory Matters	10. Regulatory Matters Capital guidelines adopted by federal and state regulatory agencies and restrictions imposed by law limit the amount of cash dividends our Bank can pay to us. Under these guidelines, the amount of dividends that may be paid in any calendar year is limited to the Bank’s current year net profits, combined with the retained net profits of the preceding two years. Further, the Bank cannot pay a dividend at any time that it has negative undivided profits. As of March 31, 2021, the Bank had positive undivided profits of $81.6 million. It is not our intent to have dividends paid in amounts that would reduce the capital of our Bank to levels below those which we consider prudent or that would not be in accordance with guidelines of regulatory authorities. We are also subject to various regulatory capital requirements. The prompt corrective action regulations establish quantitative measures to ensure capital adequacy and require minimum amounts and ratios of total, Tier 1, and common equity Tier 1 capital to risk-weighted assets and Tier 1 capital to average assets. Failure to meet minimum capital requirements can result in certain mandatory, and possibly discretionary, actions by regulators that could have a material effect on our interim condensed consolidated financial statements. In addition, capital adequacy rules include a common equity Tier 1 capital conservation buffer of 2.5% of risk-weighted assets that applies to all supervised financial institutions. To avoid limits on capital distributions and certain discretionary bonus payments we must meet the minimum ratio for adequately capitalized institutions plus the buffer. Under capital adequacy guidelines, we must meet specific capital requirements that involve quantitative measures as well as qualitative judgments by the regulators. The most recent regulatory filings as of March 31, 2021 and December 31, 2020, categorized our Bank as well capitalized. Management is not aware of any conditions or events that would have changed the most recent Federal Deposit Insurance Corporation (“FDIC”) categorization.

Fair Value Disclosures

Fair Value Disclosures	3 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Disclosures	11. Fair Value Disclosures FASB ASC topic 820 defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. FASB ASC topic 820 also establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The standard describes three levels of inputs that may be used to measure fair value: Level 1: Valuation is based upon quoted prices for identical instruments traded in active markets. Level 1 instruments include securities traded on active exchange markets, such as the New York Stock Exchange, as well as U.S. Treasury securities that are traded by dealers or brokers in active over-the-counter markets. Level 2: Valuation is based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market. Level 2 instruments include securities traded in less active dealer or broker markets. Level 3: Valuation is generated from model-based techniques that use at least one significant assumption not observable in the market. These unobservable assumptions reflect estimates of assumptions that market participants would use in pricing the asset or liability. Valuation techniques include use of option pricing models, discounted cash flow models and similar techniques. We used the following methods and significant assumptions to estimate fair value: Securities Loans held for sale Collateral dependent loans with specific loss allocations based on collateral value : From time to time, certain collateral dependent loans will have an ACL established. When the fair value of the collateral is based on an appraised value or when an appraised value is not available we record the collateral dependent loan as nonrecurring Level 3. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income data available. Such adjustments can be significant and thus will typically result in a Level 3 classification of the inputs for determining fair value Other real estate Appraisals for both collateral-dependent loans and other real estate are performed by certified general appraisers (for commercial properties) or certified residential appraisers (for residential properties) whose qualifications and licenses have been reviewed and verified by us. Once received, an independent third party, or a member of our Collateral Evaluation Department (for commercial properties), or a member of our Special Assets Group (for residential properties) reviews the assumptions and approaches utilized in the appraisal as well as the overall resulting fair value in comparison with independent data sources such as recent market data or industry-wide statistics. We compare the actual selling price of collateral that has been sold to the most recent appraised value of our properties to determine what additional adjustment, if any, should be made to the appraisal value to arrive at fair value. For commercial and residential properties we typically discount an appraisal to account for various factors that the appraisal excludes in its assumptions. These additional discounts generally do not result in material adjustments to the appraised value.

Changes in fair values for financial assets which we have elected the fair value option for the periods presented were as follows: Changes in Fair Values for the Three-Month Periods Ended March 31 for Items Measured at Fair Value Pursuant to Election of the Fair Value Option Net Gains on Assets Mortgage Total Change in Fair Values Included in Current Mortgage Loans Loan Servicing, net Period Earnings (In thousands) 2021 Loans held for sale $ (2,598 ) $ - $ (2,598 ) Capitalized mortgage loan servicing rights - 3,257 3,257 2020 Loans held for sale 523 - 523 Capitalized mortgage loan servicing rights - (6,974 ) (6,974 ) For those items measured at fair value pursuant to our election of the fair value option, interest income is recorded within the Condensed Consolidated Statements of Operations based on the contractual amount of interest income earned on these financial assets and dividend income is recorded based on cash dividends received. The following represent impairment charges recognized during the three month periods ended March 31, 2021 and 2020 relating to assets measured at fair value on a non-recurring basis: • Loans that are individually evaluated using the fair value of collateral for collateral dependent loans had a carrying amount of $2.9 million, which is net of a valuation allowance of $1.5 million at March 31, 2021, and had a carrying amount of $9.1 million, which is net of a valuation allowance of $1.8 million at December 31, 2020. The provision for credit losses included in our results of operations relating to collateral dependent loans was an expense of $0.2 million and $2.4 million during the three month periods ended March 31, 2021 and 2020, respectively. • Other real estate, which is measured using the fair value of the property, had a carrying amount of zero which is net of a valuation allowance of $0.06 million at March 31, 2021, and a carrying amount of $0.10 million which is net of a valuation allowance of $0.09 million, at December 31, 2020. An additional charge relating to other real estate measured at fair value of zero and $0.09 million was included in our results of operations during the three month periods ended March 31, 2021 and 2020, respectively. A reconciliation for all assets measured at fair value on a recurring basis using significant unobservable inputs (Level 3) follows: Capitalized Mortgage Loan Servicing Rights Three Months Ended March 31, 2021 2020 (In thousands) Beginning balance $ 16,904 $ 19,171 Total gains (losses) realized and unrealized: Included in results of operations 3,257 (6,974 ) Included in other comprehensive income - - Purchases, issuances, settlements, maturities and calls 3,369 2,632 Transfers in and/or out of Level 3 - - Ending balance $ 23,530 $ 14,829 Amount of total gains (losses) for the period included in earnings attributable to the change in unrealized gains (losses) relating to assets and liabilities still held at March 31 $ 3,257 $ (6,974 ) The fair value of our capitalized mortgage loan servicing rights has been determined based on a valuation model used by an independent third party as discussed above. The significant unobservable inputs used in the fair value measurement of the capitalized mortgage loan servicing rights are discount rate, cost to service, ancillary income, float rate and prepayment rate. Significant changes in all five of these assumptions in isolation would result in significant changes to the value of our capitalized mortgage loan servicing rights.

For the majority of these loans, we apply internal discount rates to industry valuation guides.

Fair Values of Financial Instruments [Abstract]
Fair Values of Financial Instruments	Most of our assets and liabilities are considered financial instruments. Many of these financial instruments lack an available trading market and it is our general practice and intent to hold the majority of our financial instruments to maturity. Significant estimates and assumptions were used to determine the fair value of financial instruments. These estimates are subjective in nature, involving uncertainties and matters of judgment, and therefore, fair values may not be a precise estimate. Changes in assumptions could significantly affect the estimates. Estimated fair values have been determined using available data and methodologies that are considered suitable for each category of financial instrument. For instruments with adjustable interest rates which reprice frequently and without significant credit risk, it is presumed that estimated fair values approximate the recorded book balances. The estimated recorded book balances and fair values follow: Fair Value Using Recorded Book Balance Fair Value Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Un- observable Inputs (Level 3) (In thousands) March 31 2021 Assets Cash and due from banks $ 49,220 $ 49,220 $ 49,220 $ - $ - Interest bearing deposits 81,287 81,287 81,287 - - Securities available for sale 1,247,280 1,247,280 - 1,247,280 - Federal Home Loan Bank and Federal Reserve Bank Stock 18,427 NA NA NA NA Net loans and loans held for sale 2,815,268 2,828,523 - 77,799 2,750,724 Accrued interest receivable 13,628 13,628 3 5,130 8,495 Derivative financial instruments 15,766 15,766 - 15,766 - Liabilities Deposits with no stated maturity (1) $ 3,544,206 $ 3,544,206 $ 3,544,206 $ - $ - Deposits with stated maturity (1) 314,369 316,123 - 316,123 - Other borrowings 30,006 30,404 - 30,404 - Subordinated debt 39,300 43,823 - 43,823 - Subordinated debentures 39,541 32,107 - 32,107 - Accrued interest payable 1,150 1,150 64 1,086 - Derivative financial instruments 7,365 7,365 - 7,365 - December 31, 2020 Assets Cash and due from banks $ 56,006 $ 56,006 $ 56,006 $ - $ - Interest bearing deposits 62,699 62,699 62,699 - - Securities available for sale 1,072,159 1,072,159 - 1,072,159 - Federal Home Loan Bank and Federal Reserve Bank Stock 18,427 NA NA NA NA Net loans and loans held for sale 2,790,683 2,794,058 - 92,434 2,701,624 Accrued interest receivable 12,315 12,315 3 3,414 8,898 Derivative financial instruments 16,782 16,782 - 16,782 - Liabilities Deposits with no stated maturity (1) $ 3,198,338 $ 3,198,338 $ 3,198,338 $ - $ - Deposits with stated maturity (1) 439,017 441,457 - 441,457 - Other borrowings 30,012 30,844 - 30,844 - Subordinated debt 39,281 41,417 - 41,417 - Subordinated debentures 39,524 30,265 - 30,265 - Accrued interest payable 601 601 59 542 - Derivative financial instruments 11,754 11,754 - 11,754 - (1) Deposits with no stated maturity include reciprocal deposits with a recorded book balance of $ million and $ million at March 31, 2021 and December 31, 2020 , respectively. Deposits with a stated maturity include reciprocal deposits with a recorded book balance of $ million and $ million at March 31, 2021 and December 31, 2020 , respectively. The fair values for commitments to extend credit and standby letters of credit are estimated to approximate their aggregate book balance, which is nominal and therefore are not disclosed. Fair value estimates are made at a specific point in time, based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale the entire holdings of a particular financial instrument. Fair value estimates are based on existing on- and off-balance sheet financial instruments without attempting to estimate the value of anticipated future business, the value of future earnings attributable to off-balance sheet activities and the value of assets and liabilities that are not considered financial instruments. Fair value estimates for deposit accounts do not include the value of the core deposit intangible asset resulting from the low-cost funding provided by the deposit liabilities compared to the cost of borrowing funds in the market.

Contingencies [Abstract]
Contingencies	13. Contingencies COVID-19 Pandemic On March 11, 2020, the World Health Organization declared COVID-19, the disease caused by the novel coronavirus, a pandemic as a result of the global spread of the coronavirus illness. In response to the outbreak, federal and state authorities in the U.S. introduced various measures to try to limit or slow the spread of the virus. As a result the pandemic and related government measures, Michigan has experienced an increase in unemployment. On December 11, 2020, the U.S. Food and Drug Administration (FDA) issued its first emergency use authorization for a COVID-19 vaccine. Since that time, the FDA has issued other emergency use authorizations for additional vaccines, and the United States has seen a rapid increase in the number of individuals receiving vaccinations. The U.S. Centers for Disease Control and Prevention (CDC) states that widespread vaccinations may lead to greater immunity, which ultimately is expected to result in slowing the spread of the virus The COVID-19 pandemic and the related government restrictions and guidance have had and continue to have a significant effect on us, our customers and the markets we serve. Our business, results of operations and financial condition may be adversely affected by a number of factors that could impact us and our customers, including but not limited to: • restrictions on activity and high levels of unemployment may cause increases in loan delinquencies, foreclosures and defaults; • increases in allowance for credit losses may be necessary; • declines in collateral values may occur; • third party disruptions, including outages at network providers, on-line banking vendors and other suppliers; • increased cyber and payment fraud risk, as cybercriminals attempt to profit from the disruption, given increased online and remote activity; • operational failures due to changes in our normal business practices necessitated by the pandemic and related governmental actions; and/or • key personnel or significant numbers of our employees being unable to work effectively, including because of illness or restrictions in connection with COVID-19. These factors may continue for a significant period of time. The extent to which the COVID-19 pandemic will impact our business, results of operations and financial condition will depend on future developments, which are highly uncertain and difficult to predict. Those developments and factors include, the duration and spread of the pandemic, its severity, the actions to contain the pandemic or address its impact, and how quickly and to what extent normal economic and operating conditions can resume. We do not yet know the full extent of the impact. However, the effects could have a material adverse impact on our business, asset valuations, financial condition and results of operations. Material adverse impacts may include all or a combination of valuation impairments on our intangible assets, securities available for sale, loans, capitalized mortgage loan servicing rights or deferred tax assets. Certain industries (such as hotels and restaurants) have been more adversely impacted by the COVID-19 pandemic and related periodic shut downs of our economy. We believe that the following industry concentrations within our commercial loan portfolio represent greater potential risk in the current economic environment. The balances below are as of March 31, 2021. Commercial and industrial portfolio segment: • Retail - $ million • Food service - $55 million • Hotel - $44 million Commercial real estate portfolio segment: • Retail - $ million • Office - $65 million • Multifamily - $60 million We are closely monitoring these industry concentrations and at present do not foresee any significant losses relative to this portion of our loan portfolio given the current economic conditions in Michigan and the fact that many businesses have reopened. However, a high degree of uncertainty still exists with respect to the impact of the COVID-19 pandemic and the related economic disruptions on the future performance of our loan portfolio, including these concentrations. Litigation We are involved in various litigation matters in the ordinary course of business. At the present time, we do not believe any of these matters will have a significant impact on our consolidated financial position or results of operations. The aggregate amount we have accrued for losses we consider probable as a result of these litigation matters is immaterial. However, because of the inherent uncertainty of outcomes from any litigation matter, we believe it is reasonably possible we may incur losses in addition to the amounts we have accrued. At this time, we estimate the maximum amount of additional losses that are reasonably possible is insignificant. However, because of a number of factors, including the fact that certain of these litigation matters are still in their early stages, this maximum amount may change in the future. The litigation matters described in the preceding paragraph primarily include claims that have been brought against us for damages, but do not include litigation matters where we seek to collect amounts owed to us by third parties (such as litigation initiated to collect delinquent loans). These excluded, collection-related matters may involve claims or counterclaims by the opposing party or parties, but we have excluded such matters from the disclosure contained in the preceding paragraph in all cases where we believe the possibility of us paying damages to any opposing party is remote. Loss Reimbursement Obligations The provision for loss reimbursement on sold loans represents our estimate of incurred losses related to mortgage loans that we have sold to investors (primarily Fannie Mae, Freddie Mac, Ginnie Mae and the Federal Home Loan Bank of Indianapolis). Since we sell mortgage loans without recourse, loss reimbursements only occur in those instances where we have breached a representation or warranty or other contractual requirement related to the loan sale. The provision for loss reimbursement on sold loans was an expense of $0.04 million for both three month periods ended March 31, 2021 and 2020. The reserve for loss reimbursements on sold mortgage loans totaled at March 31, 2021 and December 31, 2020 Visa Stock We own shares of VISA Class B common stock. At the present time, these shares can only be sold to other Class B shareholders. As a result, there has generally been limited transfer activity in private transactions between buyers and sellers. Given the limited activity that we have become aware of and the continuing uncertainty regarding the likelihood, ultimate timing and eventual exchange rate for Class B shares into Class A shares, we continue to carry these shares at zero, representing cost basis less impairment. However, given the current conversion ratio of Class A shares and the closing price of VISA Class A shares on April 20, 2021 of $ per share, our Class B shares would have a current “value” of approximately $ million. We continue to monitor Class B trading activity and the status of the resolution of certain litigation matters at VISA that would trigger the conversion of Class B common shares into Class A common shares, which would not have any trading restrictions.

Generally, the amount of income tax expense or benefit allocated to operations is determined without regard to the tax effects of other categories of income or loss, such as OCI. However, an exception to the general rule is provided when, in the presence of a valuation allowance against deferred tax assets, there is a pretax loss from operations and pretax income from other categories in the current period. In such instances, income from other categories must offset the current loss from operations, the tax benefit of such offset being reflected in operations. Release of material disproportionate tax effects from other comprehensive income to earnings is done by the portfolio method whereby the effects will remain in AOCIL as long as we carry a more than inconsequential portfolio of securities available for sale. A summary of reclassifications out of each component of AOCIL for the three months ended March 31 follows: AOCIL Component Amount Reclassified From AOCIL Affected Line Item in Condensed Consolidated Statements of Operations (In thousands) 2021 Unrealized gains on securities available for sale $ 1,416 Net gains on securities available for sale 297 Income tax expense $ 1,119 Reclassifications, net of tax 2020 Unrealized gains on securities available for sale $ 253 Net gains on securities available for sale - Net impairment loss recognized in earnings 253 Total reclassifications before tax 53 Income tax expense $ 200 Reclassifications, net of tax Unrealized losses on cash flow hedges $ 75 Interest expense 16 Income tax expense $ 59 Reclassification, net of tax $ 141 Total reclassifications for the period, net of tax

Revenue from Contracts with Customers [Abstract]
Revenue from Contracts with Customers	15. Revenue from Contracts with Customers We account for revenue in accordance with ASC Topic 606, Revenue from Contracts with Customers. We derive the majority of our revenue from financial instruments and their related contractual rights and obligations which for the most part are excluded from the scope of this topic. These sources of revenue that are excluded from the scope of this topic include interest income, net gains on mortgage loans, net g ains on securities available for sale Material sources of revenue that are included in the scope of this topic include service charges on deposit accounts, other deposit related income, interchange income and investment and insurance commissions and are discussed in the following paragraphs. Generally these sources of revenue are earned at the time the service is delivered or over the course of a monthly period and do not result in any contract asset or liability balance at any given period end. As a result, there were no contract assets or liabilities recorded as of March 31, 2021 and December 31, 2020.

Leases [Abstract]
Leases	16. Leases We have entered into leases in the normal course of business primarily for office facilities, some of which include renewal options and escalation clauses. Certain leases also include both lease components (fixed payments including rent, taxes and insurance costs) and non-lease components (common area or other maintenance costs) which are accounted for as a single lease component as we have elected the practical expedient to group lease and non-lease components together for all leases. We have also elected not to recognize leases with original lease terms of 12 months or less (short-term leases) on our Condensed Consolidated Statements of Financial Condition . Most of our leases include one or more options to renew. The exercise of lease renewal options is typically at our sole discretion and are included in our right of use (“ROU”) assets and lease liabilities if they are reasonably certain of exercise. Leases are classified as operating or finance leases at the lease commencement date (we did not have any finance leases as of March 31, 2021). Lease expense for operating leases and short-term leases is recognized on a straight-line basis over the lease term. The ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized at the lease commencement date based on the estimated present value of the lease payment over the lease term. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at the lease commencement date in determining the present value of the lease payments. The cost components of our operating leases follows: Three Months Ended March 31, 2021 2020 (In thousands) Operating lease cost $ 423 $ 486 Variable lease cost 16 15 Short-term lease cost 14 7 Total $ 453 $ 508 Variable lease costs consist primarily of taxes, insurance, and common area or other maintenance costs for our leased facilities. Supplemental balance sheet information related to our operating leases follows: March 31, 2021 December 31, 2020 (Dollars in thousands) Lease right of use asset (1) $ 7,268 $ 7,646 Lease liabilities (2) $ 7,478 $ 7,868 Weighted average remaining lease term (years) 7.00 7.12 Weighted average discount rate 2.4 % 2.4 % (1) Included in Accrued income and other assets (2) Included in Accrued expenses and other liabilities Maturity analysis of our lease liabilities at March 31, 2021 based on required contractual payments follows: (In thousands) Nine months ending December 31, 2021 $ 1,230 2022 1,489 2023 1,222 2024 815 2025 809 2026 and thereafter 2,529 Total lease payments 8,094 Less imputed interest (616 ) Total $ 7,478

This ASU significantly changes how entities will measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. This ASU: • Replaces the existing incurred loss impairment guidance and establishes a single allowance framework for financial assets carried at amortized cost, which will reflect our estimate of credit losses over the full remaining expected life of the financial assets and will consider expected future changes in macroeconomic conditions. • Eliminates existing guidance for purchase credit impaired (‘‘PCI’’) loans, and requires recognition of the nonaccretable difference as an increase to the allowance for expected credit losses on financial assets purchased with more than insignificant credit deterioration since origination, which will be offset by an increase in the recorded investment of the related loans. • Requires inclusion of expected recoveries, limited to the cumulative amount of prior write-offs, when estimating the ACL for in scope financial assets (including collateral dependent assets). • Amends existing impairment guidance for securities available for sale to incorporate an allowance, which will allow for reversals of credit impairments in the event that the credit of an issuer improves. Credit losses on securities available for sale are limited to the amount of the decline in fair value regardless of what the credit loss model would show for impairment. • Generally requires a cumulative-effect adjustment to retained earnings as of the beginning of the reporting period of adoption. We began evaluating this ASU in 2016 and established a company-wide, cross-discipline governance structure, which provides implementation oversight. We continued to test and refine our current expected credit loss (“CECL”) models that satisfied the requirements of this ASU. Oversight and testing, as well as efforts to meet expanded disclosure requirements, extended through the end of 2020. We currently estimate losses over approximately a forecast period using external economic forecast sources, including the Federal Open Market Committee median economic projections, and then revert to longer term historical loss experience to estimate losses over more extended periods. We were originally required to adopt this ASU on January 1, 2020 but section 4014 of the Coronavirus Aid, Relief, and Economic Security (‘‘CARES’’) Act allowed for temporary relief from applying this ASU. Under the amended CARES Act we were allowed to delay the adoption of this ASU until the earlier of the termination of the national emergency that was declared on March 13, 2020, or January 1, 2022. Early adoption was also allowed on either January 1, 2020 or January 1, 2021. As such, we chose to delay the adoption of this ASU during 2020 and adopted this ASU on January 1, 2021. Results for the reporting periods after January 1, 2021 are presented under this new ASU while prior period amounts continue to be reported in accordance with previously applicable accounting guidance We adopted this ASU using the modified retrospective method for all financial assets measured at amortized cost and unfunded lending commitments. As of January 1, 2021 we increased the ACL by $ million which was primarily driven by the longer contractual maturities of our mortgage and consumer installment loan portfolio segments. In addition, we increased the allowance for losses related to unfunded loan commitments by $ million. The ultimate impact of adopting this ASU, and at each subsequent reporting period, is highly dependent on credit quality, economic forecasts and conditions, composition of our loan portfolios and securities available for sale, along with other management judgments. As of January 1, 2021, we recorded a cumulative-effect adjustment of $ million to decrease retained earnings. Based on our evaluation of securities available for sale, we did not record an ACL on these securities under this ASU. We adopted this ASU using the prospective transition approach for financial assets purchased with credit deterioration (“PCD”) that were previously classified as PCI and accounted for under accounting standards codification (“ASC”) 310-30. In accordance with this ASU, we did not reassess whether PCI assets met the definition of PCD assets as of the date of adoption. On January 1, 2021, the amortized cost basis of the PCD assets were adjusted to reflect the addition of $ million to the ACL for loans. The remaining noncredit discount in the amount of $ million (based on the adjusted amortized cost basis) will be accreted into interest income at the effective interest rate as of January 1, 2021. The impact of the adoption of this ASU follows: As Reported Under ASU 2016-13 Pre-ASU 2016-13 Adoption Impact of ASU 2016-13 Assets Loans Commercial $ 1,242,510 $ 1,242,415 $ 95 Mortgage 1,015,944 1,015,926 18 Installment 475,358 475,337 21 Total loans 2,733,812 2,733,678 134 Allowance for credit losses (47,137 ) (35,429 ) (11,708 ) Net loans $ 2,686,675 $ 2,698,249 $ (11,574 ) Deferred tax assets (1) $ 65,196 $ 62,456 $ 2,740 Total Assets $ 4,195,179 $ 4,204,013 $ (8,834 ) Liabilities and shareholders's equity Allowance for credit losses on unfunded lending commitments (2) $ 3,274 $ 1,805 $ 1,469 Total liabilities $ 3,815,960 $ 3,814,491 $ 1,469 Retained earnings $ 29,842 $ 40,145 $ (10,303 ) Total shareholders' equity $ 379,219 $ 389,522 $ (10,303 ) Total liabilities and shareholders' equity $ 4,195,179 $ 4,204,013 $ (8,834 ) (1) Included in Accrued income and other assets in our Condensed Consolidated Statements of Financial Condition. (2) Included in Accrued expenses and other liabilities in our Condensed Consolidated Statements of Financial Condition. In March 2020, the FASB issued ASU 2020-04, ‘‘Reference Rate Reform (Topic 848), Facilitation of the Effects of Reference Rate Reform on Financial Reporting’’. This new ASU provides temporary optional expedients and exceptions to GAAP guidance on contract modifications and hedge accounting to ease the financial reporting burdens of the expected market transition from LIBOR and other interbank offered rates to alternative reference rates. Entities can elect not to apply certain modification accounting requirements to contracts affected by reference rate reform, if certain criteria are met. Entities that make such elections would not have to remeasure contracts at the modification date or reassess a previous accounting determination. Entities can elect various optional expedients that would allow them to continue applying hedge accounting for hedging relationships affected by reference rate reform, if certain criteria are met. This amended guidance and our ability to elect its temporary optional expedients and exceptions are effective for us as of March 12, 2020 through December 31, 2022.

Quantitative Information About Level 3 Fair Value Measurements Measured on a Recurring Basis and Non-recurring Basis	The fair value of our capitalized mortgage loan servicing rights has been determined based on a valuation model used by an independent third party as discussed above. The significant unobservable inputs used in the fair value measurement of the capitalized mortgage loan servicing rights are discount rate, cost to service, ancillary income, float rate and prepayment rate. Significant changes in all five of these assumptions in isolation would result in significant changes to the value of our capitalized mortgage loan servicing rights. Quantitative information about our Level 3 fair value measurements measured on a recurring basis follows: Asset Fair Value Valuation Technique Unobservable Inputs Range Weighted Average (In thousands) - - - March 31, 2021 Capitalized mortgage loan servicing rights $ 23,530 Present value of net Discount rate 10.00% to 13.00% 10.09 % servicing revenue Cost to service $ 69 to $215 $ 78 Ancillary income 20 to 37 22 Float rate 1.05 % 1.05 % Prepayment rate 7.48% to 50.27% 13.91 % December 31, 2020 Capitalized mortgage loan servicing rights $ 16,904 Present value of net Discount rate 10.00% to 13.00% 10.09 % servicing revenue Cost to service $ 69 to $289 $ 79 Ancillary income 20 to 37 22 Float rate 0.43 % 0.43 % Prepayment rate 7.92% to 64.70% 20.85 % Quantitative information about Level 3 fair value measurements measured on a non-recurring basis follows: Asset Fair Value Valuation Technique Unobservable Inputs Range Weighted Average (In thousands) - - March 31, 2021 Collateral dependent loans - Commercial $ 1,403 Sales comparison approach Adjustment for differences between comparable sales (31.0)% to 12.0% (1.5 )% Mortgage and Installment(1) 1,513 Sales comparison approach Adjustment for differences between comparable sales (73.3) to 104.6 (1.3 ) December 31, 2020 Collateral dependent loans Commercial $ 8,054 Sales comparison approach Adjustment for differences between comparable sales (40.0)% to 75.0% 3.8 % Mortgage and Installment(1) 1,020 Sales comparison approach Adjustment for differences between comparable sales (73.3) to 104.6 (1.5 ) Other real estate Mortgage 102 Sales comparison approach Adjustment for differences between comparable sales (13.1) to 2.4 (3.6 ) (1) In addition to the valuation techniques and unobservable inputs discussed above, at March 31, 2021 and December 31, 2020 certain collateral dependent installment loans totaling approximately $0.11 million and $0.16 million, respectively are secured by collateral other than real estate. For the majority of these loans, we apply internal discount rates to industry valuation guides.
