Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The Company’s Consolidated Financial Statements have been prepared in conformity with accounting principles generally accepted in the United States (“GAAP”) as set forth by the Financial Accounting Standards Board (“FASB”) and its Accounting Standards Codification (“ASC”) and Accounting Standards Updates (“ASU”) as well as the rules and interpretive releases of the U.S. Securities and Exchange Commission (“SEC”) under the authority of federal securities laws. The Consolidated Financial Statements include the accounts of the Company, its wholly-owned subsidiaries and entities in which it holds a controlling financial interest through being the primary beneficiary or through holding a majority of the voting interest. All intercompany accounts and transactions have been eliminated in consolidation. Certain previously reported amounts have been reclassified to conform to the current period’s presentation which included certain loan servicing-related costs which have been reclassified from professional services to loan expense. In addition, as a result of the decision to sell substantially all of the assets and transfer substantially all of the liabilities of Eastern Insurance Group, the Company reclassified certain amounts previously reported including: •certain assets and liabilities previously reported in the insurance agency business were reclassified to assets and liabilities of discontinued operations, respectively, on the Consolidated Balance Sheets; •certain components of noninterest income and noninterest expense previously reported in the insurance agency business were reclassified to net income from discontinued operations on the Consolidated Statements of Income; and •certain operating, investing, and financing cash flows previously reported on their applicable lines within the Consolidated Statements of Cash Flows were reclassified to cash flows used in/provided by operating activities of, investment activities of and financing activities of discontinued operations, respectively. The accompanying Consolidated Balance Sheet as of September 30, 2023, the Consolidated Statements of Income and Comprehensive Income and of Changes in Shareholders’ Equity for the three and nine months ended September 30, 2023 and 2022 and Statements of Cash Flows for the nine months ended September 30, 2023 and 2022 are unaudited. The Consolidated Balance Sheet as of December 31, 2022 was derived from the Audited Consolidated Financial Statements as of that date. The interim Consolidated Financial Statements and the accompanying notes should be read in conjunction with the annual Consolidated Financial Statements and the accompanying notes contained within the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022 (“2022 Form 10-K”), as filed with the SEC. In the opinion of management, the Company’s Consolidated Financial Statements reflect all adjustments, which include only normal recurring adjustments, necessary for a fair statement of the results of operations for the periods presented. The results for the three and nine months ended September 30, 2023 are not necessarily indicative of results to be expected for the year ending December 31, 2023, any other interim periods, or any future year or period.
Use of Estimates	Use of Estimates In preparing the Consolidated Financial Statements in conformity with GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheets and income and expenses for the periods reported. Actual results could differ from those estimates based on changing conditions, including economic conditions and future events. Material estimates that are particularly susceptible to change relate to the determination of the allowance for credit losses, valuation and fair value measurements, the liabilities for benefit obligations (particularly pensions), the provision for income taxes and impairment of goodwill and other intangibles.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Relevant standards that were recently issued but not yet adopted as of September 30, 2023: In March 2023, the FASB issued ASU 2023-02, Investments–Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method (“ASU 2023-02”). This update permits reporting entities to elect to account for their tax equity investments, regardless of the tax credit program from which the income tax credits are received, using the proportional amortization method if the following conditions are met: 1.It is probable that the income tax credits allocable to the tax equity investor will be available. 2.The tax equity investor does not have the ability to exercise significant influence over the operating and financial policies of the underlying project. 3.Substantially all of the projected benefits are from income tax credits and other income tax benefits. Projected benefits include income tax credits, other income tax benefits, and other non-income-tax-related benefits. The projected benefits are determined on a discounted basis, using a discount rate that is consistent with the cash flow assumptions used by the tax equity investor in making its decision to invest in the project. 4.The tax equity investor’s projected yield based solely on the cash flows from the income tax credits and other income tax benefits is positive. 5.The tax equity investor is a limited liability investor in the limited liability entity for both legal and tax purposes, and the tax equity investor’s liability is limited to its capital investment. Under existing accounting standards, the proportional amortization method is allowable only for equity investments in low-income-housing tax credit structures. Under the proportional amortization method, an entity amortizes the initial cost of the investment in proportion to the income tax credits and other income tax benefits received and recognizes the net amortization and income tax credits and other income tax benefits in the income statement as a component of income tax expense (benefit). Updates made by ASU 2023-02 allow a reporting entity to make an accounting policy election to apply the proportional amortization method on a tax-credit-program-by-tax-credit-program basis. The Company had previously made an accounting policy election to account for its investments in low-income-housing tax credit investments using the proportional amortization method. This election was made upon the Company’s adoption of ASU 2014-01, Investments–Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Qualified Affordable Housing Projects, which introduced the option to apply proportional amortization to low-income-housing tax credit investments. For public business entities, the amendments in ASU 2023-02 are effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. Early adoption is permitted for all entities in an interim period. The Company expects the adoption of this standard will not have a material impact on its Consolidated Financial Statements. In October 2023, the FASB issued ASU 2023-06, Disclosure Improvements–Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative (“ASU 2023-06”). The amendments in this update modify the disclosure or presentation requirements for a variety of topics in the codification. Certain amendments represent clarifications to or technical corrections of the current requirements. The following is a summary of the topics included in the update and which pertain to the Company: 1.Statement of cash flows (Topic 230): Requires an accounting policy disclosure in annual periods of where cash flows associated with derivative instruments and their related gains and loses are presented in the statement of cash flows; 2.Accounting changes and error corrections (Topic 250): Requires that when there has been a change in the reporting entity, the entity disclose any material prior-period adjustment and the effect of the adjustment on retained earnings in interim financial statements; 3.Earnings per share (Topic 260): Requires disclosure of the methods used in the diluted earnings-per-share computation for each dilutive security and clarifies that certain disclosures should be made during interim periods, and amends illustrative guidance to illustrate disclosure of the methods used in the diluted earnings per share computation; 4.Commitments (Topic 440): Requires disclosure of assets mortgaged, pledged, or otherwise subject to lien and the obligations collateralized; and 5.Debt (Topic 470): Requires disclosure of amounts and terms of unused lines of credit and unfunded commitments and the weighted-average interest rate on outstanding short-term borrowings. For public business entities, the amendments in ASU 2023-06 are effective on the date which the SEC’s removal of that related disclosure from Regulation S-X or Regulation S-K becomes effective. If by June 30, 2027, the SEC has not removed the applicable requirement from Regulation and S-X or Regulation S-K, the pending content of the related amendment will be removed from the codification and will not become effective for any entity. Early adoption is not permitted and the amendments are required to be applied on a prospective basis. The Company expects the adoption of this standard will not have a material impact on its Consolidated Financial Statements. Relevant standards that were adopted during the nine months ended September 30, 2023: In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers (“ASU 2021-08”). This update modifies how an acquiring entity measures contract assets and contract liabilities of an acquiree in a business combination in accordance with Topic 606. The amendments in this update require the acquiring entity in a business combination to account for revenue contracts as if they had originated the contract and assess how the acquiree accounted for the contract under Topic 606. ASU 2021-08 improves comparability of recognition and measurement of revenue contracts with customers both before and after a business combination. For public business entities, the amendments in this update were effective for fiscal years beginning after December 15, 2022. For all other entities, the amendments are effective for fiscal years beginning after December 15, 2023. The amendments in this update should be applied prospectively to business combinations occurring on or after the effective date of the amendments with early adoption permitted. The adoption of this standard on January 1, 2023 did not have a material impact on the Company’s Consolidated Financial Statements. In March 2022, the FASB issued ASU 2022-02, Financial Instruments–Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures (“ASU 2022-02”). The amendments in this update eliminate the accounting guidance on troubled debt restructurings (“TDRs”) for creditors in ASC 310-40 and amends the guidance on vintage disclosures, referenced in ASC 326-20-50, to require disclosure of current-period gross write-offs by year of origination. This update supersedes the existing accounting guidance for TDRs in ASC 310-40 in its entirety and requires entities to evaluate all receivable modifications under existing accounting guidance in ASC 310-20 to determine whether a modification made to a borrower results in a new loan or a continuation of an existing loan. In addition to the elimination of TDR accounting guidance, entities that adopt this update will no longer consider renewals, modifications and extensions that result from reasonably expected TDRs in their calculation of the allowance for credit losses. Further, if an entity employs a discounted cash flow method to calculate the allowance for credit losses, it will be required to use a post-modification-derived effective interest rate as part of its calculation. This update also requires new disclosures for receivables for which there has been a modification in their contractual cash flows resulting from borrowers experiencing financial difficulties. For public business entities, the amendments in this update were effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Entities may elect to apply the updated guidance on TDR recognition and measurement by using a modified retrospective transition method. The amendments on TDR disclosures and vintage disclosures should be adopted prospectively. On January 1, 2023, the Company adopted this standard by using the modified retrospective transition method, except with regard to amendments on TDR and vintage disclosures which were adopted prospectively. Accordingly, the Company recorded a cumulative-effect adjustment to retained earnings as of January 1, 2023. The adoption of this standard did not have a material impact on the Company’s Consolidated Financial Statements.
Allowance for Loan Losses - Loans Held for Investment	Allowance for Loan Losses - Loans Held for Investment Modifications of Loans to Borrowers Experiencing Financial Difficulty The amendments in ASU 2022-02 eliminated the accounting guidance for TDRs by creditors in Subtopic 310-40, Receivables—Troubled Debt Restructurings by Creditors, while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty. Thus, as a result of adoption of this standard on January 1, 2023, rather than applying the recognition and measurement guidance for TDRs, the Company now applies the loan refinancing and restructuring guidance codified in paragraphs 310-20-35-9 through 35-11 of the Accounting Standards Codification to determine whether a modification results in a new loan or a continuation of an existing loan. Modifications to borrowers experiencing financial difficulty include principal forgiveness, interest rate reductions, term extensions, other-than-insignificant payment delays and combinations thereof. Expected losses or recoveries related to loans where modifications have been granted to borrowers experiencing financial difficulty have been included in the Company’s determination of the allowance for loan losses. Upon adoption of ASU 2022-02, the Company is no longer required to use a discounted cash flow method to measure the allowance for loan losses resulting from a modification to a borrower experiencing financial difficulty. Accordingly, the Company now applies the same credit methodology it uses for similar loans that were not modified. As previously indicated, the Company adopted ASU 2022-02 using the modified retrospective transition method. Accordingly, upon adoption, commercial loan TDRs existing at that time which were measured using a discounted cash flow methodology and all residential real estate and consumer home equity loan TDRs were transitioned to the applicable segment of loans collectively evaluated for impairment based upon their risk characteristics. Commercial loan TDRs determined to be collateral dependent continue to be assessed for impairment on an individual basis. Prior to the Company’s adoption of ASU 2022-02, in cases where a borrower was experiencing financial difficulties and the Company made certain concessionary modifications to contractual terms, the loan was classified as a TDR. Modifications included adjustments to interest rates, extensions of maturity, consumer loans where the borrower’s obligations had been effectively discharged through Chapter 7 bankruptcy and the borrower had not reaffirmed the debt to the Company, and other actions intended to minimize economic loss and avoid foreclosure or repossession of collateral. Management identified loans as TDR loans when it had a reasonable expectation that it would execute a TDR modification with a borrower. In addition, management estimated expected credit losses on a collective basis if a group of TDR loans shared similar risk characteristics. If a TDR loan’s risk characteristics were not similar to those of any of the Company’s other TDR loans, expected credit losses on the TDR loan were measured individually. The impairment analysis discounted the present value of the anticipated cash flows by the loan’s contractual rate of interest in effect prior to the loan’s modification or the fair value of collateral if the loan was collateral dependent. The amount of credit loss, if any, was recorded as a specific loss allocation to each individual loan or as a loss allocation to the pool of loans, for those loans for which credit loss was measured on a collective basis, in the allowance for credit losses. Any commercial (commercial and industrial, commercial real estate, commercial construction, and business banking loans) or residential loan that had been classified as a TDR and which subsequently defaulted was reviewed to determine if the loan should be deemed collateral-dependent. In such an instance, any shortfall between the value of the collateral and the book value of the loan was determined by measuring the recorded investment in the loan against the fair value of the collateral less costs to sell.

Summary of Significant Accounting Policies (Policies)

9 Months Ended

Sep. 30, 2023

The Company’s Consolidated Financial Statements have been prepared in conformity with accounting principles generally accepted in the United States (“GAAP”) as set forth by the Financial Accounting Standards Board (“FASB”) and its Accounting Standards Codification (“ASC”) and Accounting Standards Updates (“ASU”) as well as the rules and interpretive releases of the U.S. Securities and Exchange Commission (“SEC”) under the authority of federal securities laws.

The Consolidated Financial Statements include the accounts of the Company, its wholly-owned subsidiaries and entities in which it holds a controlling financial interest through being the primary beneficiary or through holding a majority of the voting interest. All intercompany accounts and transactions have been eliminated in consolidation.

Certain previously reported amounts have been reclassified to conform to the current period’s presentation which included certain loan servicing-related costs which have been reclassified from professional services to loan expense. In addition, as a result of the decision to sell substantially all of the assets and transfer substantially all of the liabilities of Eastern Insurance Group, the Company reclassified certain amounts previously reported including:

•certain assets and liabilities previously reported in the insurance agency business were reclassified to assets and liabilities of discontinued operations, respectively, on the Consolidated Balance Sheets;

•certain components of noninterest income and noninterest expense previously reported in the insurance agency business were reclassified to net income from discontinued operations on the Consolidated Statements of Income; and

•certain operating, investing, and financing cash flows previously reported on their applicable lines within the Consolidated Statements of Cash Flows were reclassified to cash flows used in/provided by operating activities of, investment activities of and financing activities of discontinued operations, respectively.

The accompanying Consolidated Balance Sheet as of September 30, 2023, the Consolidated Statements of Income and Comprehensive Income and of Changes in Shareholders’ Equity for the three and nine months ended September 30, 2023 and 2022 and Statements of Cash Flows for the nine months ended September 30, 2023 and 2022 are unaudited. The Consolidated Balance Sheet as of December 31, 2022 was derived from the Audited Consolidated Financial Statements as of that date. The interim Consolidated Financial Statements and the accompanying notes should be read in conjunction with the annual Consolidated Financial Statements and the accompanying notes contained within the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022 (“2022 Form 10-K”), as filed with the SEC. In the opinion of management, the Company’s Consolidated Financial Statements reflect all adjustments, which include only normal recurring adjustments, necessary for a fair statement of the results of operations for the periods presented. The results for the three and nine months ended September 30, 2023 are not necessarily indicative of results to be expected for the year ending December 31, 2023, any other interim periods, or any future year or period.

Use of Estimates

In preparing the Consolidated Financial Statements in conformity with GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheets and income and expenses for the periods reported. Actual results could differ from those estimates based on changing conditions, including economic conditions and future events. Material estimates that are particularly susceptible to change relate to the determination of the allowance for credit losses, valuation and fair value measurements, the liabilities for benefit obligations (particularly pensions), the provision for income taxes and impairment of goodwill and other intangibles.

Recent Accounting Pronouncements

Relevant standards that were recently issued but not yet adopted as of September 30, 2023:

In March 2023, the FASB issued ASU 2023-02, Investments–Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method (“ASU 2023-02”). This update permits reporting entities to elect to account for their tax equity investments, regardless of the tax credit program from which the income tax credits are received, using the proportional amortization method if the following conditions are met:

1.It is probable that the income tax credits allocable to the tax equity investor will be available.

2.The tax equity investor does not have the ability to exercise significant influence over the operating and financial policies of the underlying project.

3.Substantially all of the projected benefits are from income tax credits and other income tax benefits. Projected benefits include income tax credits, other income tax benefits, and other non-income-tax-related benefits. The projected benefits are determined on a discounted basis, using a discount rate that is consistent with the cash flow assumptions used by the tax equity investor in making its decision to invest in the project.

4.The tax equity investor’s projected yield based solely on the cash flows from the income tax credits and other income tax benefits is positive.

5.The tax equity investor is a limited liability investor in the limited liability entity for both legal and tax purposes, and the tax equity investor’s liability is limited to its capital investment.

Under existing accounting standards, the proportional amortization method is allowable only for equity investments in low-income-housing tax credit structures. Under the proportional amortization method, an entity amortizes the initial cost of the investment in proportion to the income tax credits and other income tax benefits received and recognizes the net amortization and income tax credits and other income tax benefits in the income statement as a component of income tax expense (benefit). Updates made by ASU 2023-02 allow a reporting entity to make an accounting policy election to apply the proportional amortization method on a tax-credit-program-by-tax-credit-program basis. The Company had previously made an accounting policy election to account for its investments in low-income-housing tax credit investments using the proportional amortization method. This election was made upon the Company’s adoption of ASU 2014-01, Investments–Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Qualified Affordable Housing Projects, which introduced the option to apply proportional amortization to low-income-housing tax credit investments. For public business entities, the amendments in ASU 2023-02 are effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. Early adoption is permitted for all entities in an interim period. The Company expects the adoption of this standard will not have a material impact on its Consolidated Financial Statements.

In October 2023, the FASB issued ASU 2023-06, Disclosure Improvements–Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative (“ASU 2023-06”). The amendments in this update modify the disclosure or presentation requirements for a variety of topics in the codification. Certain amendments represent

clarifications to or technical corrections of the current requirements. The following is a summary of the topics included in the update and which pertain to the Company:

1.Statement of cash flows (Topic 230): Requires an accounting policy disclosure in annual periods of where cash flows associated with derivative instruments and their related gains and loses are presented in the statement of cash flows;

2.Accounting changes and error corrections (Topic 250): Requires that when there has been a change in the reporting entity, the entity disclose any material prior-period adjustment and the effect of the adjustment on retained earnings in interim financial statements;

3.Earnings per share (Topic 260): Requires disclosure of the methods used in the diluted earnings-per-share computation for each dilutive security and clarifies that certain disclosures should be made during interim periods, and amends illustrative guidance to illustrate disclosure of the methods used in the diluted earnings per share computation;

4.Commitments (Topic 440): Requires disclosure of assets mortgaged, pledged, or otherwise subject to lien and the obligations collateralized; and

5.Debt (Topic 470): Requires disclosure of amounts and terms of unused lines of credit and unfunded commitments and the weighted-average interest rate on outstanding short-term borrowings.

For public business entities, the amendments in ASU 2023-06 are effective on the date which the SEC’s removal of that related disclosure from Regulation S-X or Regulation S-K becomes effective. If by June 30, 2027, the SEC has not removed the applicable requirement from Regulation and S-X or Regulation S-K, the pending content of the related amendment will be removed from the codification and will not become effective for any entity. Early adoption is not permitted and the amendments are required to be applied on a prospective basis. The Company expects the adoption of this standard will not have a material impact on its Consolidated Financial Statements.

Relevant standards that were adopted during the nine months ended September 30, 2023:

In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers (“ASU 2021-08”). This update modifies how an acquiring entity measures contract assets and contract liabilities of an acquiree in a business combination in accordance with Topic 606. The amendments in this update require the acquiring entity in a business combination to account for revenue contracts as if they had originated the contract and assess how the acquiree accounted for the contract under Topic 606. ASU 2021-08 improves comparability of recognition and measurement of revenue contracts with customers both before and after a business combination. For public business entities, the amendments in this update were effective for fiscal years beginning after December 15, 2022. For all other entities, the amendments are effective for fiscal years beginning after December 15, 2023. The amendments in this update should be applied prospectively to business combinations occurring on or after the effective date of the amendments with early adoption permitted. The adoption of this standard on January 1, 2023 did not have a material impact on the Company’s Consolidated Financial Statements.

In March 2022, the FASB issued ASU 2022-02, Financial Instruments–Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures (“ASU 2022-02”). The amendments in this update eliminate the accounting guidance on troubled debt restructurings (“TDRs”) for creditors in ASC 310-40 and amends the guidance on vintage disclosures, referenced in ASC 326-20-50, to require disclosure of current-period gross write-offs by year of origination.

The amendments on TDR disclosures and vintage disclosures should be adopted prospectively. On January 1, 2023, the Company adopted this standard by using the modified retrospective transition method, except with regard to amendments on TDR and vintage disclosures which were adopted prospectively. Accordingly, the Company recorded a cumulative-effect adjustment to retained earnings as of January 1, 2023. The adoption of this standard did not have a material impact on the Company’s Consolidated Financial Statements.

Allowance for Loan Losses - Loans Held for Investment

Modifications of Loans to Borrowers Experiencing Financial Difficulty

The amendments in ASU 2022-02 eliminated the accounting guidance for TDRs by creditors in Subtopic 310-40, Receivables—Troubled Debt Restructurings by Creditors, while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty. Thus, as a result of adoption of this standard on January 1, 2023, rather than applying the recognition and measurement guidance for TDRs, the Company now applies the loan refinancing and restructuring guidance codified in paragraphs 310-20-35-9 through 35-11 of the Accounting Standards Codification to determine whether a modification results in a new loan or a continuation of an existing loan.

Modifications to borrowers experiencing financial difficulty include principal forgiveness, interest rate reductions, term extensions, other-than-insignificant payment delays and combinations thereof. Expected losses or recoveries related to loans where modifications have been granted to borrowers experiencing financial difficulty have been included in the Company’s determination of the allowance for loan losses. Upon adoption of ASU 2022-02, the Company is no longer required to use a discounted cash flow method to measure the allowance for loan losses resulting from a modification to a borrower experiencing financial difficulty. Accordingly, the Company now applies the same credit methodology it uses for similar loans that were not modified. As previously indicated, the Company adopted ASU 2022-02 using the modified retrospective transition method. Accordingly, upon adoption, commercial loan TDRs existing at that time which were measured using a discounted cash flow methodology and all residential real estate and consumer home equity loan TDRs were transitioned to the applicable segment of loans collectively evaluated for impairment based upon their risk characteristics. Commercial loan TDRs determined to be collateral dependent continue to be assessed for impairment on an individual basis.

Prior to the Company’s adoption of ASU 2022-02, in cases where a borrower was experiencing financial difficulties and the Company made certain concessionary modifications to contractual terms, the loan was classified as a TDR. Modifications included adjustments to interest rates, extensions of maturity, consumer loans where the borrower’s obligations had been effectively discharged through Chapter 7 bankruptcy and the borrower had not reaffirmed the debt to the Company, and other actions intended to minimize economic loss and avoid foreclosure or repossession of collateral. Management identified loans as TDR loans when it had a reasonable expectation that it would execute a TDR modification with a borrower. In addition, management estimated expected credit losses on a collective basis if a group of TDR loans shared similar risk characteristics. If a TDR loan’s risk characteristics were not similar to those of any of the Company’s other TDR loans, expected credit losses on the TDR loan were measured individually. The impairment analysis discounted the present value of the anticipated cash flows by the loan’s contractual rate of interest in effect prior to the loan’s modification or the fair value of collateral if the loan was collateral dependent. The amount of credit loss, if any, was recorded as a specific loss allocation to each individual loan or as a loss allocation to the pool of loans, for those loans for which credit loss was measured on a collective basis, in the allowance for credit losses. Any commercial (commercial and industrial, commercial real estate, commercial construction, and business banking loans) or residential loan that had been classified as a TDR and which subsequently defaulted was reviewed to determine if the loan should be deemed collateral-dependent. In such an instance, any shortfall between the value of the collateral and the book value of the loan was determined by measuring the recorded investment in the loan against the fair value of the collateral less costs to sell.
