Loans and Leases Receivable Disclosure [Abstract]

The composition of the Company’s loan portfolio, excluding residential loans held for sale, was as follows for the dates indicated:


(In thousands)	September 30, 2020		December 31, 2019
Commercial Loans:
Commercial real estate	$	1,333,733	$	1,243,397
Commercial	360,629		421,108
SBA PPP	223,838		—
HPFC	14,919		21,593
Total commercial loans	1,933,119		1,686,098
Retail Loans:
Residential real estate	1,044,103		1,070,374
Home equity	274,743		312,779
Consumer	22,877		25,772
Total retail loans	1,341,723		1,408,925
Total loans	$	3,274,842	$	3,095,023

The loan balances for each portfolio segment presented above are net of their respective unamortized fair value mark discount on acquired loans and net of unamortized loan origination costs for the dates indicated:


(In thousands)	September 30, 2020		December 31, 2019
Net unamortized fair value mark discount on acquired loans	$	(1,667)	$	(2,593)
Net unamortized loan (fees) origination costs(1)	(2,439)		3,111
Total	$	(4,106)	$	518

(1) The change in net unamortized loan (fees) origination costs from December 31, 2019 to September 30, 2020, was primarily driven by origination fees capitalized upon origination of SBA PPP loans during the second and third quarters of 2020. As of September 30, 2020, unamortized loan fees on originated SBA PPP loans were $5.4 million.

The Company's lending activities are primarily conducted in Maine, but also include loan production offices in Massachusetts and New Hampshire. The Company originates single- and multi-family residential loans, commercial real estate loans, business loans, municipal loans and a variety of consumer loans. In addition, the Company makes loans for the construction of residential homes, multi-family properties and commercial real estate properties. The ability and willingness of borrowers to honor their repayment commitments is generally dependent on the level of overall economic activity within the geographic area and the general economy.

The HPFC loan portfolio is an acquired loan portfolio. It consists of niche commercial lending to the small business medical field, including dentists, optometrists and veterinarians, across the U.S. The ability and willingness of borrowers to honor their repayment commitments is generally dependent on the success of the borrower's business. In 2016, the Company closed HPFC's operations and is no longer originating HPFC loans.

The Company participated in SBA PPP funding to qualifying businesses in the second and third quarter of 2020. Through September 30, 2020, the Company originated 3,034 SBA PPP loans totaling $244.8 million to qualifying businesses across our markets in need of financial support due to the COVID-19 pandemic. This program provided qualifying businesses a specialized low-interest loan by the U.S. Treasury Department and is administered by the SBA. The PPP provides borrower guarantees for lenders, as well as loan forgiveness incentives for borrowers that utilize the loan proceeds to cover employee compensation-related business operating costs, as well as certain other costs up to pre-established limits.

In the normal course of business, the Bank makes loans to certain officers, directors and their associated companies, under terms that are consistent with the Company's lending policies and regulatory requirements and that do not involve more than the normal risk of collectability or present other unfavorable features. At September 30, 2020 and December 31, 2019, outstanding loans to certain officers, directors and their associated companies was less than 5% of the Company's shareholders' equity.

The ALL is management’s best estimate of the inherent risk of loss in the Company’s loan portfolio as of the consolidated statement of condition date. Management makes various assumptions and judgments about the collectability of the loan portfolio and provides an allowance for potential losses based on a number of factors including historical losses. If those assumptions are incorrect, the ALL may not be sufficient to cover losses and may cause an increase in the allowance in the future. Among the factors that could affect the Company’s ability to collect loans and require an increase to the allowance in the future are: (i) financial condition of borrowers; (ii) real estate market changes; (iii) state, regional, and national economic conditions, including consideration of the effect and impact of the COVID-19 pandemic; and (iv) a requirement by federal and state regulators to increase the provision for loan losses or recognize additional charge-offs. The Company has accounted for the estimated impact of the COVID-19 pandemic on its loan portfolio as of September 30, 2020 through adjustments to its economic qualitative factor ("Q-factor"), based on available information, as the Company has not yet experienced any significant COVID-19 credit deterioration through September 30, 2020.

As discussed in Note 2, the Company did not adopt ASU 2016-04, commonly referred to as "CECL", during the nine months ended September 30, 2020. The Company's ALL, as presented, has been determined in accordance with its policies and procedures described within its Annual Report on Form 10-K for the year ended December 31, 2019.

As of and for the three and nine months ended September 30, 2020, the Company has disclosed SBA PPP loans as a standalone loan segment, separate from the Company's commercial loan segment, as the credit risk profiles differ. Refer to discussion of each loan segment's risk characteristics below for further details. There were no other significant changes to the Company's ALL methodology during the three or nine months ended September 30, 2020.

The Board of Directors monitors credit risk through: (i) the Directors' Loan Review Committee, which reviews large credit exposures, monitors the external loan review reports, reviews the lending authority for individual loan officers when required, and has approval authority and responsibility for all matters regarding the loan policy and other credit-related policies, including reviewing and monitoring asset quality trends, concentration levels, and the ALL methodology under the incurred loss accounting methodology for March 31, 2020 and periods prior to; and (ii) the Audit Committee, which, effective June 30, 2020, has approval authority and oversight responsibility for ALL adequacy and methodology. The change in governance structure for the ALL methodology was done to align with the governance structure that will exist upon implementation of CECL on December 31, 2020, effective retrospectively as of January 1, 2020.

Credit Risk Administration and the Credit Risk Policy Committee oversee the Company's systems and procedures to monitor the credit quality of its loan portfolio, conduct a loan review program, and maintain the integrity of the loan rating system. Effective for annual and interim periods beginning January 1, 2020, the adequacy of the ALL is overseen by the Management Provision Committee, which is an internal management committee comprised of various Company executives and senior managers across business lines, including Accounting and Finance, Credit Risk, Compliance, and Commercial and Retail Banking. The Management Provision Committee is further supported by other management-level committees to ensure the adequacy of the ALL under the incurred model, as well as the CECL methodology upon adoption. The Management Provision Committee supports the oversight efforts of the director-level committees discussed in the paragraph above and the Board of Directors. The Company's practice is to manage the portfolio proactively such that management can identify problem credits early, assess and implement effective work-out strategies, and take charge-offs as promptly as practical. In addition, the Company continuously reassesses its underwriting standards in response to credit risk posed by changes in economic conditions.

For purposes of determining the ALL, the Company disaggregated its loans into portfolio segments, which include commercial real estate, commercial, SBA PPP, HPFC, residential real estate, home equity and consumer. Each portfolio segment possesses unique risk characteristics that are considered when determining the appropriate level of allowance. These risk characteristics unique to each portfolio segment include the following:

Commercial Real Estate. Commercial real estate loans consist of mortgage loans to finance investments in real property such as multi-family residential, commercial/retail, office, industrial, hotels, educational, health care facilities and other specific use properties. Commercial real estate loans are typically written with amortizing payment structures. Collateral values are determined based upon appraisals and evaluations in accordance with established policy guidelines. Loan-to-value ratios at origination are governed by established policy and regulatory guidelines. Commercial real estate loans are primarily paid by the cash flow generated from the real property, such as operating leases, rents, or other operating cash flows from the borrower.

Commercial. Commercial loans consist of revolving and term loan obligations extended to business and corporate enterprises for the purpose of financing working capital and/or capital investment. Collateral generally consists of pledges of business assets including, but not limited to, accounts receivable, inventory, plant and equipment, and/or real estate, if applicable. Commercial loans are primarily paid by the operating cash flow of the borrower. Commercial loans may be secured or unsecured.

SBA PPP. SBA PPP loans are unsecured, fully-guaranteed commercial loans backed by the SBA, issued to qualifying small businesses as part of federal stimulus issued in response to the COVID-19 pandemic. Loans made under the PPP have terms of two or five years and are to be used by the borrower to offset certain payroll and other operating costs, such as rent and utilities. The loan and accrued interest, or a portion thereof, is eligible for forgiveness by the SBA should the qualifying small business meet certain conditions. PPP loans were originated under the guidance of the SBA, which has been subject to change.

HPFC. Prior to the Company's closing of HPFC's operations in 2016, it provided commercial lending to dentists, optometrists and veterinarians, many of which were start-up companies. HPFC's loan portfolio consists of term loan obligations extended for the purpose of financing working capital and/or purchase of equipment. Collateral consists of pledges of business assets including, but not limited to, accounts receivable, inventory, and/or equipment. These loans are primarily paid by the operating cash flow of the borrower.

Residential Real Estate. Residential real estate loans held in the Company's loan portfolio are made to borrowers who demonstrate the ability to make scheduled payments with full consideration to underwriting factors. Borrower qualifications include favorable credit history combined with supportive income requirements and combined loan-to-value ratios within established policy guidelines. Collateral consists of mortgage liens on one- to four-family residential properties, including for investment purposes.

Home Equity. Home equity loans and lines of credit are made to qualified individuals for legitimate purposes secured by senior or junior mortgage liens on owner-occupied one- to four-family homes, condominiums, or vacation homes. The home equity loan has a fixed rate and is billed as equal payments comprised of principal and interest. The home equity line of credit has a variable rate and is billed as interest-only payments during the draw period. At the end of the draw period, the home equity line of credit is billed as a percentage of the principal balance plus all accrued interest. Borrower qualifications include favorable credit history combined with supportive income requirements and combined loan-to-value ratios within established policy guidelines.

Consumer. Consumer loan products include personal lines of credit and amortizing loans made to qualified individuals for various purposes such as education, auto loans, debt consolidation, personal expenses or overdraft protection. Borrower qualifications include favorable credit history combined with supportive income and collateral requirements within established policy guidelines. Consumer loans may be secured or unsecured.

(1) The provision (credit) for loan losses excludes any impact for the change in the reserve for unfunded commitments, which represents management's estimate of the amount required to reflect the probable inherent losses on outstanding letters of credit and unused lines of credit. The reserve for unfunded commitments is presented within accrued interest and other liabilities on the consolidated statements of condition. At September 30, 2020 and 2019, and December 31, 2019, the reserve for unfunded commitments was $9,000, $11,000 and $21,000, respectively.

The following reconciles the provision for loan losses to the provision for credit losses as presented on the consolidated statements of income for the periods indicated:


	Three Months Ended September 30,				Nine Months Ended September 30,				Year Ended December 31, 2019
(In thousands)	2020		2019		2020		2019

Provision for credit losses	$	987	$	730	$	12,160	$	2,647	$	2,861

The Company focuses on maintaining a well-balanced and diversified loan portfolio. Despite such efforts, it is recognized that credit concentrations may occasionally emerge as a result of economic conditions, changes in local demand, natural loan growth and runoff. To identify credit concentrations effectively, all commercial and commercial real estate loans are assigned Standard Industrial Classification codes, North American Industry Classification System codes, and state and county codes. Shifts in portfolio concentrations are monitored. As of September 30, 2020, the Company's total exposure to the lessors of nonresidential buildings' industry was 13% of total loans and 32% of total commercial real estate loans. There were no other industry exposures exceeding 10% of the Company's total loan portfolio as of September 30, 2020.

COVID-19 Loan Deferral Program:

In response to the COVID-19 pandemic, the Company worked with businesses and consumers to provide temporary debt payment relief that generally provided principal and/or interest payment deferrals for a period of 180 days or less. For loans temporarily modified due to the COVID-19 pandemic, under the CARES Act and regulatory guidance, the Company may apply the following accounting treatment in this order:

1.The Company may account for a loan modification in accordance with Section 4013 of the CARES Act if the loan modification (i) meets the criteria set forth in Section 4013 of the CARES Act and (ii) the Company elects to apply Section 4013 of the CARES Act. Section 4013 of the CARES Act suspended TDR designation for loan modifications related to the COVID-19 pandemic. In order for the loan modification to qualify under Section 4013 of the CARES Act, the loan must not have been more than 30 days past due as of December 31, 2019. This guidance is applicable for loan modifications beginning on March 1, 2020 and ending on the earlier of (i) December 31, 2020, or (ii) the date that is 60 days after the date the national emergency concerning the COVID-19 pandemic declared by the President on March 13, 2020 under the National Emergencies Act terminates.

2.Should a loan modification (i) not meet the criteria set forth in Section 4013 of the CARES Act or (ii) the Company elects to not apply Section 4013 of the CARES Act, but the loan modification (a) meets the criteria provided in the "Interagency Statement on Loan Modifications and Reporting for Financial Institutions Working with Customers Affected by the Coronavirus (Revised)," issued by the banking agencies on April 7, 2020, and (b) the Company elects to apply this guidance, then the Company may account for the loan modification in accordance with the interagency guidance. Under this guidance, if the loan was no more than 30 days past due at the time the loan modification program was implemented, the modification was short-term in duration (generally, less than six months), and the modification was related to the COVID-19 pandemic, then it may be presumed that the borrower is not experiencing financial difficulty, and, therefore, that the modification does not qualify as a TDR.

3.Should a loan modification (i) not meet the criteria set forth in Section 4013 of the CARES Act or the interagency guidance described above, or (ii) the Company elects not to apply the guidance, then the Company would assess the loan modification under its existing accounting policies (GAAP).

All loans granted temporary payment relief by the Company complied with the terms of the CARES Act or bank regulator guidance, and, thus, were not individually assessed, designated or accounted for as TDRs.

For the dates indicated, the Company's loans impacted by the COVID-19 pandemic and operating under temporary short-term payment deferral arrangements for a period of 180 days or less were as follows:

Total	712	$	181,216	5.5	%	1,763	$	546,722	16.4	%

To further identify loans with similar risk profiles, the Company categorizes each portfolio segment into classes by credit risk characteristic and applies a credit quality indicator to each portfolio segment. The indicators for loans in commercial, commercial real estate, residential real estate, and HPFC portfolio segments are represented by Grades 1 through 10 as outlined below. In general, risk ratings are adjusted periodically throughout the year as updated analysis and review warrants. This process may include, but is not limited to, annual credit and loan reviews, periodic reviews of loan performance metrics, such as delinquency rates, and quarterly reviews of adversely risk rated loans.

The Company uses the following definitions when assessing grades for the purpose of evaluating the risk and adequacy of the ALL:

•Grade 1 through 6 — Grades 1 through 6 represent groups of loans that are not subject to adverse criticism as defined in regulatory guidance. Loans in these groups exhibit characteristics that represent low to moderate risks, which is measured using a variety of credit risk criteria, such as cash flow coverage, debt service coverage, balance sheet leverage, liquidity, management experience, industry position, prevailing economic conditions, support from secondary sources of repayment and other credit factors that may be relevant to a specific loan. In general, these loans are supported by properly margined collateral and guarantees of principal parties.

•Grade 7 — Loans with potential weakness (Special Mention). Loans in this category are currently protected based on collateral and repayment capacity and do not constitute undesirable credit risk, but have potential weakness that may result in deterioration of the repayment process at some future date. This classification is used if a negative trend is evident in the obligor’s financial situation. Special mention loans do not sufficiently expose the Company to warrant adverse classification.

•Grade 8 — Loans with definite weakness (Substandard). Loans classified as substandard are inadequately protected by the current sound worth and paying capacity of the obligor or by collateral pledged. Borrowers experience difficulty in meeting debt repayment requirements. Deterioration is sufficient to cause the Company to look to the sale of collateral.

•Grade 9 — Loans with potential loss (Doubtful). Loans classified as doubtful have all the weaknesses inherent in the substandard grade with the added characteristic that the weaknesses make collection or liquidation of the loan in full highly questionable and improbable. The possibility of some loss is extremely high, but because of specific pending factors that may work to the advantage and strengthening of the asset, its classification as an estimated loss is deferred until its more exact status may be determined.

•Grade 10 — Loans with definite loss (Loss). Loans classified as loss are considered uncollectible. The loss classification does not mean that the asset has absolutely no recovery or salvage value, but rather that it is not practical or desirable to defer writing off the asset because recovery and collection time may be protracted.

Loans that were granted temporary debt relief due to the COVID-19 pandemic were not automatically downgraded into lower credit risk ratings. The Company will continue to actively monitor these loans for indications of deterioration as the deferral period matures, which could result in future downgrades.

The Company periodically reassesses asset quality indicators to reflect appropriately the risk composition of the Company’s loan portfolio. Home equity and consumer loans are not individually risk rated, but rather analyzed as groups taking into account delinquency rates and other economic conditions which may affect the ability of borrowers to meet debt service requirements, including interest rates and energy costs. Performing loans include loans that are current and loans that are past due less than 90 days. Loans that are past due over 90 days and non-accrual loans, including TDRs, are considered non-performing.

The following summarizes credit risk exposure indicators by portfolio segment as of the following dates:

In the second quarter of 2020, the Company downgraded one loan from special mention (Grade 7) to substandard (Grade 8), which drove the increase in substandard (Grade 8) loans for the nine months ended September 30, 2020. The loan was downgraded as a result of the Company's assessment of the borrower's 2019 financial performance and was not directly related to the impact of the COVID-19 pandemic on the borrower.

The Company closely monitors the performance of its loan portfolio. A loan is placed on non-accrual status when the financial condition of the borrower is deteriorating, payment in full of both principal and interest is not expected as scheduled or principal or interest has been in default for 90 days or more. Exceptions may be made if the asset is secured by collateral sufficient to satisfy both the principal and accrued interest in full and collection is reasonably assured. When one loan to a borrower is placed on non-accrual status, all other loans to the borrower are re-evaluated to determine if they should also be placed on non-accrual status. All previously accrued and unpaid interest is reversed at this time. A loan may return to accrual status when collection of principal and interest is assured and the borrower has demonstrated timely payments of principal and interest for a reasonable period, generally at least six months. Unsecured loans, however, are not normally placed on non-accrual status because they are charged-off once their collectability is in doubt.

All loans that were granted temporary payment relief due to the COVID-19 pandemic were current with payments in accordance with the terms of the CARES Act or bank regulatory guidance at the time of initial relief. At September 30, 2020, the payment status for loans that continued to operate under a payment deferral arrangement were reported based on payment status at the time the deferral was granted to the borrower.

The following is a loan aging analysis by portfolio segment (including loans past due over 90 days and non-accrual loans) and a summary of non-accrual loans, which include TDRs, and loans past due over 90 days and accruing as of the following dates:

Interest income that would have been recognized if loans on non-accrual status had been current in accordance with their original terms is estimated to have been $85,000 and $106,000 for the three months ended September 30, 2020 and 2019, respectively. For the nine months ended September 30, 2020 and 2019, the interest income that is estimated to have been recognized if loans on non-accrual status had been current in accordance with their original terms was $251,000 and $330,000, respectively.

TDRs:

The Company takes a conservative approach with credit risk management and remains focused on community lending and reinvesting. The Company works closely with borrowers experiencing credit problems to assist in loan repayment or term modifications. TDRs consist of loans where the Company, for economic or legal reasons related to the borrower’s financial difficulties, granted a concession to the borrower that it would not otherwise consider. TDRs typically involve term modifications or a reduction of either interest or principal. Once such an obligation has been restructured, it will remain a TDR until paid in full, or until the loan is again restructured at current market rates and no concessions are granted.

The specific reserve allowance was determined by discounting the total expected future cash flows from the borrower at the original loan interest rate, or if the loan is currently collateral-dependent, using the net realizable value, which was obtained through independent appraisals and internal evaluations. The following is a summary of TDRs, by portfolio segment, and the associated specific reserve included within the ALL for the dates indicated:

At September 30, 2020, the Company had performing and non-performing TDRs with a recorded investment balance of $3.0 million and $454,000, respectively. At December 31, 2019, the Company had performing and non-performing TDRs with a recorded investment balance of $3.0 million and $636,000, respectively.

There were no loan modifications that qualify as TDRs that occurred for the three and nine months ended September 30, 2020 and 2019.

For the three and nine months ended September 30, 2020 and 2019, no loans were modified as TDRs within the previous 12 months for which the borrower subsequently defaulted.

Loan Sales:

For the three months ended September 30, 2020 and 2019, the Company sold $182.7 million and $86.9 million, respectively, of fixed rate residential mortgage loans on the secondary market, which resulted in gains on the sale of loans (net of costs) of $4.3 million and $1.9 million, respectively. For the nine months ended September 30, 2020 and 2019, the Company sold $449.7 million and $164.5 million, respectively, of fixed rate residential mortgage loans on the secondary market, which resulted in gains on the sale of loans (net of costs) of $10.4 million and $3.9 million.

At September 30, 2020 and December 31, 2019, the Company had certain residential mortgage loans with a principal balance of $37.3 million and $11.9 million, respectively, designated as held for sale. The Company has elected the fair value option of accounting for its loans held for sale, and at September 30, 2020 and December 31, 2019, recorded an unrealized gain (loss) of $634,000 and ($61,000), respectively. For the three months ended September 30, 2020 and 2019, the Company recorded an unrealized loss on loans held for sale recorded within mortgage banking income, net, on the Company's consolidated statements of income of $47,000 and $205,000, respectively.

The Company has forward delivery commitments with a secondary market investor on each of its loans held for sale at September 30, 2020 and December 31, 2019. Refer to Note 8 for further discussion of the Company's forward delivery commitments.

In-Process Foreclosure Proceedings:

At September 30, 2020 and December 31, 2019, the Company had $1.7 million and $1.3 million, respectively, of consumer mortgage loans secured by residential real estate properties for which foreclosure proceedings were in process. Due to the COVID-19 pandemic, the Company has been abiding by state issued mandates requiring a temporary moratorium on foreclosures. The Company will continue to work these consumer mortgage loans through the foreclosure process once the moratorium is lifted, which typically takes 18 to 24 months.

FHLB Advances:

FHLB advances are those borrowings from the FHLBB greater than 90 days. FHLB advances are collateralized by a blanket lien on qualified collateral consisting primarily of loans with first mortgages secured by one- to four-family properties, certain commercial real estate loans, certain pledged investment securities and other qualified assets. The carrying value of residential real estate and commercial loans pledged as collateral was $1.3 billion and $1.4 billion at September 30, 2020 and December 31, 2019, respectively.

Refer to Notes 3 and 6 of the consolidated financial statements for discussion of securities pledged as collateral.
