Accounting Policies [Abstract]
SIGNIFICANT ACCOUNTING POLICIES	SIGNIFICANT ACCOUNTING POLICIES Nature of Operations Sandy Spring Bancorp, Inc. ("Bancorp" or, together with its subsidiaries, the "Company"), a Maryland corporation, is the bank holding company for Sandy Spring Bank (the “Bank”). Independent and community-oriented, the Bank offers a broad range of commercial banking, retail banking, mortgage services and trust services throughout central Maryland, northern Virginia, and the greater Washington, D.C. market. The Bank also offers a comprehensive menu of wealth management services through its subsidiaries, West Financial Services, Inc. (“West Financial”) and SSB Wealth Management, Inc. (d/b/a Rembert Pendleton Jackson, "RPJ”) . Basis of Presentation The accounting and reporting policies of the Company conform to accounting principles generally accepted in the United States of America (“GAAP”) and prevailing practices within the financial services industry for financial information. The following summary of significant accounting policies of the Company is presented to assist the reader in understanding the financial and other data presented in this report. Certain prior period amounts have been reclassified to conform to the current period presentation. Such reclassifications had no impact on the Company’s net income and shareholders’ equity. The Company has evaluated subsequent events through the date of the issuance of its financial statements. Principles of Consolidation The consolidated financial statements include the accounts of the Company and its wholly owned subsidiary, Sandy Spring Bank and its subsidiaries. Consolidation has resulted in the elimination of all significant intercompany accounts and transactions. Use of Estimates The preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements, in addition to affecting the reported amounts of revenues earned and expenses incurred during the reporting period. Actual results could differ from those estimates. Estimates that could change significantly relate to the provision for credit losses and the related allowance, potential impairment of goodwill or other intangible assets, valuation of investment securities and the determination of whether available-for-sale debt securities with fair values less than amortized costs are impaired and require an allowance for credit losses, valuation of other real estate owned, valuation of share based compensation, the assessment that a liability should be recognized with respect to any matters under litigation, the calculation of current and deferred income taxes, and the actuarial projections related to pension expense and the related liability. Assets Under Management Assets held for others under fiduciary and agency relationships are not assets of the Company or its subsidiaries and are not included in the accompanying Consolidated Statements of Condition. Trust department income and investment management fees are presented on an accrual basis. Cash Flows For purposes of reporting cash flows, cash and cash equivalents include cash and due from banks, federal funds sold and interest-bearing deposits with banks (items with an original maturity of three months or less). Revenue from Contracts with Customers The Company’s revenue includes net interest income on financial instruments and non-interest income. Specific categories of revenue are presented in the Consolidated Statements of Income. Most of the Company’s revenue is not within the scope of Accounting Standard Codification (“ASC”) 606 – Revenue from Contracts with Customers. For revenue within the scope of ASC 606, the Company provides services to customers and has related performance obligations. The revenue from such services is recognized upon satisfaction of all contractual performance obligations. The following discusses key revenue streams within the scope of revenue recognition guidance. West Financial and RPJ provide comprehensive investment management and financial planning services. Wealth management income is comprised of income for providing trust, estate and investment management services. Trust services include acting as a trustee for corporate or personal trusts. Investment management services include investment management, record-keeping and reporting of security portfolios. Fees for these services are recognized based on a contractually-agreed fixed percentage applied to net assets under management at the end of each reporting period. The Company does not charge/recognize any performance-based fees. Prior to the sale of its assets in June 2022, Sandy Spring Insurance Corporation performed the function of an insurance intermediary by introducing the policyholder and insurer and was compensated by a commission fee for placement of an insurance policy. Sandy Spring Insurance did not provide any captive management services or any claim handling services. Commission fees were set as a percentage of the premium for the insurance policy for which Sandy Spring Insurance was a producer. Sandy Spring Insurance recognized revenue when the insurance policy was contractually agreed to by the insurer and policyholder (at transaction date). Service charges on deposit accounts are earned on depository accounts for consumer and commercial account holders and include fees for account and overdraft services. Account services include fees for event-driven services and periodic account maintenance activities. An obligation for event-driven services is satisfied at the time of the event when service is delivered and revenue recognized as earned. Obligation for maintenance activities is satisfied over the course of each month and revenue is recognized at month end. The overdraft services obligation is satisfied at the time of the overdraft and revenue is recognized as earned. Residential Mortgage Loans Held for Sale The Company engages in sales of residential mortgage loans originated by the Bank. Loans held for sale are carried at fair value. Fair value is derived from secondary market quotations for similar instruments. The Company measures residential mortgage loans at fair value when the Company first recognizes the loan (i.e., the fair value option). Changes in fair value of these loans are recorded in earnings as a component of mortgage banking activities in non-interest income in the Consolidated Statements of Income. The Company's current practice is to sell the majority of such loans on a servicing released basis. Any retained servicing assets are amortized in proportion to their net servicing fee income over the life of the respective loans. Servicing assets are evaluated for impairment on a periodic basis. Investments Held-to-maturity Debt securities that are purchased with the positive intent and ability to be held until their maturity are classified as held-to-maturity (“HTM”). HTM debt securities are recorded at cost adjusted for amortization of premiums and accretion of discounts. Transfers of debt securities from available-for-sale ("AFS") category to HTM category are made at fair value as of the transfer date. The unrealized gain or loss at the date of transfer continues to be reported in accumulated other comprehensive income and in the carrying amount of the HTM securities. Both amounts are amortized over the remaining life of the security as a yield adjustment in interest income and effectively offset each other. Investments Available-for-Sale Debt securities not classified as held-to-maturity or trading are classified as securities available-for-sale. Securities available-for-sale are acquired as part of the Company's asset/liability management strategy and may be sold in response to changes in interest rates, loan demand, changes in prepayment risk or other factors. Securities available-for-sale are carried at fair value, with unrealized gains or losses based on the difference between amortized cost and fair value, reported net of deferred tax, as accumulated other comprehensive income/ (loss), a separate component of stockholders' equity. The amortized cost of securities available-for-sale are adjusted for premium amortization and discount accretion. Premium is amortized to the earliest call date and discount accreted to the maturity date using the effective interest method. Realized gains and losses on security sales or maturities, using the specific identification method, are included as a separate component of non-interest income. Related interest and dividend income are included in interest income. Declines in the fair value of individual available-for-sale securities below their amortized cost due to credit-related factors are recognized as an allowance for credit losses. Credit-related factors affecting the determination of whether impairment has occurred include a downgrading of the security below investment grade by a rating agency or due to potential default, a significant deterioration in the financial condition of the issuer, increase in entity-specific credit spreads. Additionally, on any available-for-sale securities with unrealized losses, the Company evaluates its intent and ability to hold the investment for a period of time sufficient to allow for any anticipated recovery in fair value. Other Investments Equity securities include Federal Reserve Bank stock, Federal Home Loan Bank of Atlanta ("FHLB") stock and other equities that are considered restricted as to marketability and recorded at cost. As these securities do not have readily available market values, they are carried at cost and adjusted for any necessary impairments each reporting period. Loan Financing Receivables The Company’s financing receivables consist primarily of loans that are stated at their principal balance outstanding, net of any unearned income, acquisition fair value marks and deferred loan origination fees and costs. Interest income on loans is accrued at the contractual rate based on the principal balance outstanding. Loan origination fees, net of certain direct origination costs, are deferred and recognized as an adjustment of the related loan yield using the interest method. Loans are considered past due or delinquent when the principal or interest due in accordance with the contractual terms of the loan agreement or any portion thereof remains unpaid after the due date of the scheduled payment. Immaterial shortfalls in payment amounts do not necessarily result in a loan being considered delinquent or past due. If any payments are past due and subsequent payments are resumed without payment of the delinquent amount, the loan shall continue to be considered past due. Whenever any loan is reported delinquent on a principal or interest payment or portion thereof, the amount reported as delinquent is the outstanding principal balance of the loan. Loans, except for consumer installment loans, are placed into non-accrual status when any portion of the loan principal or interest becomes 90 days past due. Management may determine that certain circumstances warrant earlier discontinuance of interest accruals on specific loans if an evaluation of other relevant factors (such as bankruptcy, interruption of cash flows, etc.) indicates collection of amounts contractually due is unlikely. These loans are considered, collectively, to be non-performing loans. Consumer installment loans that are not secured by real estate are not placed on non-accrual, but are charged down to their net realizable value when they are four months past due. Loans designated as non-accrual have all previously accrued but unpaid interest reversed. Interest income is not recognized on non-accrual loans. All payments received on non-accrual loans are applied using a cost-recovery method to reduce the outstanding principal balance until the loan returns to accrual status. Loans may be returned to accrual status when all principal and interest amounts contractually due are brought current and future payments are reasonably assured. On January 1, 2023, the Company adopted provisions of ASU 2022-02, "Financial Instruments - Credit Losses (Topic 326)", which eliminated accounting guidance for troubled debt restructurings ("TDRs") by creditors and expanded disclosures about modifications. Prior to the effective adoption date, the Company considered loans to be TDRs if their terms were restructured (e.g., interest rates, loan maturity date, payment and amortization period, etc.) in circumstances that provided a payment concession to a borrower experiencing financial difficulty. Loans could be removed from a TDR category if the borrower no longer experienced financial difficulty, a re-underwriting event took place, and the revised loan terms of the subsequent restructuring agreement were considered to be consistent with terms that could be obtained in the market for loans with comparable credit risk. Subsequent to the effective adoption date of ASU 2022-02, the Company continues to offer modifications to certain borrowers experiencing financial difficulty, mainly in the form of interest rate concessions or term extensions, without classifying and accounting for them as TDRs. Allowance for Credit Losses The allowance for credit losses (“allowance” or “ACL”) represents an amount which, in management's judgment, reflects the lifetime expected losses that may be sustained on outstanding loans at the balance sheet date based on the evaluation of the size and current risk characteristics of the loan portfolio, past events, current conditions, reasonable and supportable forecasts of future economic conditions and prepayment experience. The allowance is measured and recorded upon the initial recognition of a financial asset. The allowance is reduced by charge-offs, net of recoveries of previous losses, and is increased or decreased by a provision or credit for credit losses, which is recorded as a current period expense. Determination of the appropriateness of the allowance is inherently complex and requires the use of significant and highly subjective estimates. The reasonableness of the allowance is reviewed by the Risk Committee of the Board of Directors and formally approved quarterly by that same committee of the Board. The Company’s methodology for estimating the allowance includes: (1) a collective quantified reserve that reflects the Company’s historical default and loss experience adjusted for expected economic conditions throughout a reasonable and supportable period and the Company’s prepayment and curtailment rates; (2) collective qualitative factors that consider the expected impact of certain factors not fully captured in the collective quantified reserve, including concentrations of the loan portfolio, expected changes to the economic forecasts, large relationships, early delinquencies, and factors related to credit administration, including, among others, loan-to-value ratios, borrowers’ risk rating and credit score migrations; and (3) individual allowances on collateral-dependent loans where borrowers are experiencing financial difficulty or when the Company determines that the foreclosure is probable. The Company excludes accrued interest from the measurement of the allowance as the Company has a non-accrual policy to reverse any accrued, uncollected interest income as loans are moved to non-accrual status. Loans are pooled into segments based on the similar risk characteristics of the underlying borrowers, in addition to consideration of collateral type, industry and business purpose of the loans. Portfolio segments used to estimate the allowance are the same as portfolio segments used for general credit risk management purposes. Refer to Note 4 for more details on the Company’s portfolio segments. The Company applies two calculation methodologies to estimate the collective quantified component of the allowance: discounted cash flows method and weighted average remaining life method. Allowance estimates on commercial acquisition, development and construction (“AD&C”) and residential construction segments are based on the weighted average remaining life method. Allowance estimates on all other portfolio segments are based on the discounted cash flows method. Segments utilizing the discounted cash flows method are further sub-segmented into risk level pools, determined either by risk rating for commercial loans or Beacon Scores ranges for residential and consumer loans. To better manage risk and reasonably determine the sufficiency of reserves, this segregation allows the Company to monitor the allowance component applicable to higher risk loans separate from the remainder of the portfolio. Collective calculation methodologies utilize the Company’s historical default and loss experience adjusted for future economic forecasts. The reasonable and supportable forecast period represents a two-year economic outlook for the applicable economic variables. Following the end of the reasonable and supportable forecast period expected losses revert back to the historical mean over the next two years on a straight-line basis. Economic variables that have the most significant impact on the allowance include: unemployment rate, house price index and business bankruptcies. Contractual loan level cash flows within the discounted cash flows methodology are adjusted for the Company’s historical prepayment and curtailment rate experience. The individual reserve assessment is applied to collateral dependent loans where borrowers are experiencing financial difficulty or when the Company determines that a foreclosure is probable. The determination of the fair value of the collateral depends on whether a repayment of the loan is expected to be from the sale or the operation of the collateral. When a repayment is expected from the operation of the collateral, the Company uses the present value of expected cash flows from the operation of the collateral as the fair value. When the repayment of the loan is expected from the sale of the collateral the fair value of the collateral is based on an observable market price or the collateral’s appraised value, less estimated costs to sell. Third-party appraisals used in the individual reserve assessment are conducted at least annually with underlying assumptions that are reviewed by management. Third-party appraisals may be obtained on a more frequent basis if deemed necessary. Internal evaluations of collateral value are conducted quarterly to ensure any further deterioration of the collateral value is recognized on a timely basis. During the individual reserve assessment, management also considers the potential future changes in the value of the collateral over the remainder of the loan’s remaining life. The Company may receive updated appraisals which contradict the preliminary determination of fair value used to establish an individual allowance on a loan. In these instances the individual allowance is adjusted to reflect the Company’s evaluation of the updated appraised fair value. In the event a loss was previously confirmed and the loan was charged down to the estimated fair value based on a previous appraisal, the balance of partially charged-off loans are not subsequently increased, but could be further decreased depending on the direction of the change in fair value. Payments on fully or partially charged-off loans are accounted for under the cost-recovery method. Under this method, all payments received are applied on a cash basis to reduce the entire outstanding principal balance, then to recognize a recovery of all previously charged-off amounts before any interest income may be recognized. Based on the individual reserve assessment, if the Company determines that the fair value of the collateral is less than the amortized cost basis of the loan, an individual allowance will be established measured as the difference between the fair value of the collateral (less costs to sell) and the amortized cost basis of the loan. Once a loss has been confirmed, the loan is charged-down to its estimated fair value. Large groups of smaller non-accrual homogeneous loans are not individually evaluated for allowance and include residential permanent and construction mortgages and consumer installment loans. These portfolios are reserved for on a collective basis using historical loss rates of similar loans over the weighted average life of each pool. Unfunded lending commitments are reviewed to determine if they are considered unconditionally cancellable. The Company establishes reserves for unfunded commitments that do not meet that criteria as a liability in the Consolidated Statements of Condition. Changes to the liability are recorded through the provision for credit losses in the Consolidated Statements of Income. The establishment of the reserves for unfunded commitments considers both the likelihood that the funding will occur and an estimate of the expected credit losses over the life of the respective commitments. Management believes it uses relevant information available to make determinations about the allowance for credit losses and the reserve for unfunded commitments and that it has established both reserves in accordance with GAAP. However, the determination of the allowance requires significant judgment, and estimates of expected lifetime losses in the loan portfolio can vary significantly from the amounts actually observed. While management uses available information to recognize expected losses, future additions to the allowance may be necessary based on changes in the loans comprising the portfolio, changes in the current and forecasted economic conditions, changes to the interest rate environment which may directly impact prepayment and curtailment rate assumptions, and changes in the financial condition of borrowers. Premises and Equipment Premises and equipment are stated at cost, less accumulated depreciation and amortization, computed using the straight-line method. Premises and equipment are depreciated over the useful lives of the assets, which generally range from 3 to 10 years for furniture, fixtures and equipment, 3 to 5 years for computer software and hardware, and 10 to 40 years for buildings and building improvements. Leasehold improvements are amortized over the lesser of the lease term or the estimated useful lives of the improvements. The costs of major renewals and betterments are capitalized, while the costs of ordinary maintenance and repairs are included in non-interest expense. Leases The Company determines if an arrangement is a lease at inception. All of the Company’s leases are currently classified as operating leases and are included in other assets and other liabilities on the Company’s Consolidated Statements of Condition. Periodic operating lease costs are recorded in occupancy expenses of premises on the Company's Consolidated Statements of Income. Right-of-use (“ROU”) assets represent the Company’s right to use an underlying asset for the lease term, and lease liabilities represent the Company’s obligation to make lease payments arising from the lease arrangements. Operating lease ROU assets and liabilities are recognized at the lease commencement date based on the present value of the expected future lease payments over the remaining lease term. In determining the present value of future lease payments, the Company uses its incremental borrowing rate based on the information available at the lease commencement date. The operating ROU assets are adjusted for any lease payments made at or before the lease commencement date, initial direct costs, any lease incentives received and, for acquired leases, any favorable or unfavorable fair value adjustments. The present value of the lease liability may include the impact of options to extend or terminate the lease when it is reasonably certain that the Company will exercise such options provided in the lease terms. Lease expense is recognized on a straight-line basis over the expected lease term. Lease agreements that include lease and non-lease components, such as common area maintenance charges, are accounted for separately. Segment Reporting Operating segments are components of a business about which separate financial information is available and evaluated regularly by the chief operating decision maker in deciding how to allocate resources and assessing performance. The Bank is the Company’s only reportable operating segment upon which management makes decisions regarding how to allocate resources and assess performance. While the Company’s chief operating decision maker has some limited financial information about its various financial products and services, that information is not complete since it does not include a full allocation of revenue, costs, and capital from key corporate functions; therefore, the Company evaluates financial performance on a company-wide basis. Management continues to evaluate the Company's business units for separate reporting as facts and circumstances change. Goodwill and Other Intangible Assets Goodwill represents the excess purchase price paid over the fair value of the net assets acquired in a business combination. Goodwill is not amortized but is tested for impairment annually or more frequently if events or changes in circumstances indicate that the asset might be impaired. Impairment testing requires that the fair value of each of the Company’s reporting units be compared to the carrying amount of the reporting unit’s net assets, including goodwill. The Company’s reporting units were identified based upon an analysis of each of its individual operating segments. If the fair values of the reporting units exceed their book values, no write-down of recorded goodwill is required. If the fair value of a reporting unit is less than book value, an expense may be required to write-down the related goodwill to the proper carrying value. Any impairment would be realized through a reduction of goodwill or the intangible and an offsetting charge to non-interest expense. Accounting guidance provides the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. The Company assesses qualitative factors on a quarterly basis. Based on the assessment of these qualitative factors, if it is determined that it is more likely than not that the fair value of a reporting unit is not less than the carrying value, then performing the impairment process is not necessary. However, if it is determined that it is more likely than not that the carrying value exceeds the fair value a quantified analysis is required to determine whether an impairment exists. Other intangible assets represent purchased assets that lack physical substance but can be distinguished from goodwill because of contractual or other legal rights and capitalized development, implementation, and license costs of internal-use licensed software. Other intangible assets have finite lives and are reviewed for impairment annually. The amortization of internal-use licensed software begins when a module or a component of a licensed software is ready for its intended use. Other intangible assets are amortized over their estimated useful lives either on a straight-line or sum-of-the-years basis over varying periods that initially do not exceed 15 years. Annually, the Company performs an impairment test of goodwill as of October 1 of each year. During the current year, management performed both quarterly qualitative assessments and an annual quantitative impairment test, as a result of the economic uncertainty and increased market volatility resulting from the rising interest rate environment. The Company's annual impairment test of goodwill and other intangible assets did not identify any impairment. Additionally, the Company determined that there were no triggering events and as a result no evidence of impairment between the annual impairment test and December 31, 2023. Other Real Estate Owned OREO is comprised of properties acquired in partial or total satisfaction of problem loans. The properties are recorded at fair value less estimated costs of disposal, on the date acquired or on the date that the Company acquires effective control over the property. Gains or losses arising at the time of acquisition of such properties are charged against the allowance for credit losses. During the holding period OREO continues to be measured at lower of cost or fair value less estimated costs of disposal, and any subsequent declines in value are expensed as incurred. Gains and losses realized from the sale of OREO, as well as valuation adjustments and expenses of operation are included in non-interest expense. Derivative Financial Instruments Derivative Loan Commitments Mortgage loan commitments are derivative loan commitments if the loan that will result from exercise of the commitment will be held for sale upon funding. Derivative loan commitments are recognized at fair value in the Consolidated Statements of Condition in other assets or other liabilities with changes in their fair values recorded as a component of mortgage banking activities in the Consolidated Statements of Income. Mortgage loan commitments are issued to borrowers. Subsequent to commitment date, changes in the fair value of the loan commitment are recognized based on changes in the fair value of the underlying mortgage loan due to interest rate changes, changes in the probability the derivative loan commitment will be exercised, and the passage of time. In estimating fair value, a probability is assigned to a loan commitment based on an expectation that it will be exercised and the loan will be funded. Forward Loan Sale Commitments Loan sales agreements are evaluated to determine whether they meet the definition of a derivative as facts and circumstances may differ significantly. If agreements qualify, to protect against the price risk inherent in derivative loan commitments, the Company utilizes both “mandatory delivery” and “best efforts” forward loan sale commitments to mitigate the risk of potential decreases in the values of loans that would result from the exercise of the derivative loan commitments. Mandatory delivery contracts are accounted for as derivative instruments. Generally, best efforts contracts also meet the definition of derivative instruments after the loan to the borrower has closed. Accordingly, forward loan sale commitments that economically hedge the closed loan inventory are recognized at fair value in the Consolidated Statements of Condition in other assets or other liabilities with changes in their fair values recorded as a component of mortgage banking activities in the Consolidated Statements of Income. The Company estimates the fair value of its forward loan sales commitments using a methodology similar to that used for derivative loan commitments. Interest Rate Swap Agreements The Company enters into interest rate swaps (“swaps”) with commercial loan customers to provide a facility to mitigate the fluctuations in the variable rate on the respective loans. These swaps are matched in exact offsetting terms to swaps that the Company enters into with an outside third party. The swaps are reported at fair value in other assets or other liabilities in the Consolidated Statements of Condition. The Company's swaps qualify as derivatives, but are not designated as hedging instruments, thus any net gain or loss resulting from changes in the fair value is recognized in other non-interest income in the Consolidated Statements of Income. Further discussion of the Company's financial derivatives is set forth in Note 18. Off-Balance Sheet Credit Risk The Company issues financial or standby letters of credit that represent conditional commitments to fund transactions by the Company, typically to guarantee performance of a customer to a third-party related to borrowing arrangements. The credit risk associated with issuing letters of credit is essentially the same as occurs when extending loan facilities to borrowers. The Company monitors the exposure to the letters of credit as part of its credit review process. Extensions of letters of credit, if any, would become part of the loan balance outstanding and would be evaluated in accordance with the Company’s credit policies. Potential exposure to loss for unfunded letters of credit if deemed necessary would be recorded in other liabilities in the Consolidated Statements of Condition. In the ordinary cours

Investments, Debt and Equity Securities [Abstract]
INVESTMENTS	INVESTMENTS Investments available-for-sale and held-to-maturity During 2022, the Company transferred certain debt securities from available-for-sale to held-to-maturity. The total amortized cost of debt securities transferred was $305.6 million with the associated fair value of $289.4 million and unrealized losses of $16.2 million at the date of transfer. All of these investments are either issued by a direct governmental entity or a government-sponsored entity and have no historical evidence supporting expected credit losses. Therefore, the Company has estimated these losses at zero and will monitor this assumption in the future for any economic or governmental policies that could affect this assumption. There were no additional transfers of debt securities from available-for-sale to held-to-maturity during 2023. The amortized cost and estimated fair values of investments available-for-sale and held-to-maturity at December 31 are presented in the following table: 2023 2022 (In thousands) Amortized Cost Gross Unrealized Gross Unrealized Estimated Fair Amortized Cost Gross Unrealized Gross Unrealized Estimated Fair Available-for-sale debt securities U.S. treasuries and government agencies $ 101,678 $ — $ (4,751) $ 96,927 $ 100,926 $ — $ (7,304) $ 93,622 State and municipal 311,505 1 (43,292) 268,214 322,519 4 (56,526) 265,997 Mortgage-backed and asset-backed 807,636 181 (70,277) 737,540 943,398 73 (88,552) 854,919 Total available-for-sale debt securities $ 1,220,819 $ 182 $ (118,320) $ 1,102,681 $ 1,366,843 $ 77 $ (152,382) $ 1,214,538 Held-to-maturity debt securities: Mortgage-backed and asset-backed 236,165 — (35,754) 200,411 259,452 — (39,329) 220,123 Total held-to-maturity debt securities $ 236,165 $ — $ (35,754) $ 200,411 $ 259,452 $ — $ (39,329) $ 220,123 Total debt securities $ 1,456,984 $ 182 $ (154,074) $ 1,303,092 $ 1,626,295 $ 77 $ (191,711) $ 1,434,661 Any unrealized losses in the U.S. treasuries and government agencies, state and municipal, mortgage-backed and asset-backed available-for-sale debt securities at December 31, 2023 are due to changes in interest rates and not credit-related events. As such, no allowance for credit losses is required at December 31, 2023. Unrealized losses on available-for-sale debt securities are expected to recover over time as these securities approach maturity. The Company does not intend to sell, nor is it more likely than not it will be required to sell, these securities and has sufficient liquidity to hold these securities for an adequate period of time, which may be maturity, to allow for any anticipated recovery in fair value. The available-for-sale and held-to-maturity mortgage-backed and asset-backed securities portfolio at December 31, 2023 is composed entirely of either the most senior tranches of GNMA, FNMA or FHLMC collateralized mortgage obligations ($441.2 million), GNMA, FNMA or FHLMC mortgage-backed securities ($562.7 million) and SBA asset-backed securities ($39.9 million).

Receivables [Abstract]
LOANS	LOANS The lending business of the Company is based on understanding, measuring and controlling the credit risk inherent in the loan portfolio. The Company’s loan portfolio is subject to varying degrees of credit risk. Credit risk entails both general risks, which are inherent in the process of lending, and risk specific to individual borrowers. The Company’s credit risk is mitigated through portfolio diversification, which limits exposure to any single customer, industry or collateral type. Outstanding loan balances at December 31, 2023 and 2022 are net of unearned income, including net deferred loan fees of $7.0 million and $10.5 million, respectively. The loan portfolio segment balances at December 31 are presented in the following table: (In thousands) 2023 2022 Commercial real estate: Commercial investor real estate $ 5,104,425 $ 5,130,094 Commercial owner-occupied real estate 1,755,235 1,775,037 Commercial AD&C 988,967 1,090,028 Commercial business 1,504,880 1,455,885 Total commercial loans 9,353,507 9,451,044 Residential real estate: Residential mortgage 1,474,521 1,287,933 Residential construction 121,419 224,772 Consumer 417,542 432,957 Total residential and consumer loans 2,013,482 1,945,662 Total loans $ 11,366,989 $ 11,396,706 Portfolio Segments The Company currently manages its credit products and the respective exposure to credit losses (credit risk) by the following specific portfolio segments which are levels at which the Company develops and documents its systematic methodology to determine the allowance for credit losses attributable to each respective portfolio segment. These segments are: • Commercial investor real estate loans - Commercial investor real estate loans consist of loans secured by nonowner-occupied properties where an established banking relationship exists and involves investment properties for warehouse, retail, and office space with a history of occupancy and cash flow. This commercial investor real estate category contains mortgage loans to the developers and owners of commercial real estate where the borrower intends to operate or sell the property at a profit and use the income stream or proceeds from the sale(s) to repay the loan. • Commercial owner-occupied real estate loans - Commercial owner-occupied real estate loans consist of commercial mortgage loans secured by owner-occupied properties where an established banking relationship exists and involves a variety of property types to conduct the borrower’s operations. The decision to extend a loan is based upon the borrower’s financial health and the ability of the borrower and the business to repay. The primary source of repayment for this type of loan is the cash flow from the operations of the business. • Commercial acquisition, development and construction loans - Commercial acquisition, development and construction loans are intended to finance the construction of commercial properties and include loans for the acquisition and development of land. Construction loans represent a higher degree of risk than permanent real estate loans and may be affected by a variety of additional factors such as the borrower’s ability to control costs and adhere to time schedules and the risk that constructed units may not be absorbed by the market within the anticipated time frame or at the anticipated price. The loan commitment on these loans often includes an interest reserve that allows the lender to periodically advance loan funds to pay interest charges on the outstanding balance of the loan. • Commercial business loans - Commercial loans are made to provide funds for equipment and general corporate needs. Repayment of a loan primarily comes from the funds obtained from the operation of the borrower’s business. Commercial loans also include lines of credit that are utilized to finance a borrower’s short-term credit needs and/or to finance a percentage of eligible receivables and inventory. • Residential mortgage loans - The residential mortgage loans category contains permanent mortgage loans principally to consumers secured by residential real estate. Residential real estate loans are evaluated for the adequacy of repayment sources at the time of approval, based upon measures including credit scores, debt-to-income ratios, and collateral values. Loans may be either conforming or non-conforming. • Residential construction loans - The Company makes residential construction loans generally to provide interim financing on residential property during the construction period. Borrowers are typically individuals who will ultimately occupy the single-family dwelling. Loan funds are disbursed periodically as pre-specified stages of completion are attained based upon site inspections. • Consumer loans - This category of loans includes primarily home equity loans and lines, installment loans, personal lines of credit, and other loans. The home equity category consists mainly of revolving lines of credit to consumers which are secured by residential real estate. These loans are typically secured with second mortgages on the homes. Other consumer loans include installment loans used by customers to purchase automobiles, boats and recreational vehicles.

Each borrower is evaluated at least annually with more frequent evaluation of more severely criticized loans. The indicators represent the rating for loans as of the date presented is based on the most recent credit review performed. These credit quality indicators are defined as follows: Pass - A pass rated credit is not adversely classified because it does not display any of the characteristics for adverse classification. Special mention - A special mention credit has potential weaknesses that deserve management’s close attention. If uncorrected, such weaknesses may result in deterioration of the repayment prospects or collateral position at some future date. Special mention assets are not adversely classified and do not warrant adverse classification. Substandard - A substandard loan is inadequately protected by the current net worth and payment capacity of the obligor or of the collateral pledged, if any. Loans classified as substandard generally have a well-defined weakness, or weaknesses, that jeopardize the liquidation of the debt. These loans are characterized by the distinct possibility of loss if the deficiencies are not corrected. Doubtful - A loan that is classified as doubtful has all the weaknesses inherent in a loan classified as substandard with added characteristics that the weaknesses make collection or liquidation in full highly questionable and improbable, on the basis of currently existing facts, conditions and values. Loss – Loans classified as a loss are considered uncollectible and of such little value that their continuing to be carried as a loan is not warranted. This classification is not necessarily equivalent to no potential for recovery or salvage value, but rather that it is not appropriate to defer a full write-off even though partial recovery may be effected in the future.

As a part of our risk management practices, we may consider modifying a loan for a borrower experiencing a financial difficulty that provides a certain degree of a payment relief. Modification types primarily include a reduction in the interest rate or an extension of the existing term. We do not provide modifications that result in the reduction of the outstanding principal balance. The following table presents the amount of the loans modified during the year ended December 31, 2023 to borrowers experiencing financial difficulty, disaggregated by the loan portfolio segment, type of modification granted and the financial effect of loans modified: For the Year Ended December 31, 2023 Interest rate reduction Term extension Rate reduction & Term extension Total Interest rate reduction Term extension (in thousands) Amount Amount Amount Amount % of total loan segment Weighted Average Weighted Average Commercial Investor R/E $ 28,970 $ 9,778 $ 13,560 $ 52,308 1.0 % 1.5 % 15 Months Commercial Owner-Occupied R/E — 2,808 — 2,808 0.2 % — % 14 Months Commercial AD&C — 1,016 — 1,016 0.1 % — % 9 Months Commercial Business 233 5,496 — 5,729 0.4 % 0.3 % 14 Months All Other loans — — — — — % — % — Total $ 29,203 $ 19,098 $ 13,560 $ 61,861 0.5 % Unfunded loan commitments on modifications for borrowers experiencing financial difficulty totaled $2.8 million at December 31, 2023.

TDR loans are subject to periodic credit reviews to determine the necessity and appropriateness of an individual credit loss allowance based on the collectability of the recorded investment in the TDR loan. Loans restructured during 2022 had individual reserves of $1.2 million at December 31, 2022.

Equity [Abstract]
STOCKHOLDERS' EQUITY	STOCKHOLDERS’ EQUITY The Company’s Articles of Incorporation authorize 100,000,000 shares of capital stock (par value $1.00 per share). Issued shares have been classified as common stock. The Articles of Incorporation provide that remaining unissued shares may later be designated as either common or preferred stock. The Company maintains an employee stock purchase plan (the “Purchase Plan”) that enables employees to purchase up to $25,000 of Company common stock each year at a discount. The Purchase Plan, which was initially authorized on July 1, 2011, was amended and restated as of November 18, 2020. As part of the amendment and restatement, an additional 700,000 shares of common stock were reserved to be issued, which is in addition to the 300,000 shares of common stock authorized for purchase under the previous version of the Purchase Plan. Under the Purchase Plan, shares are purchased at 85% of the lower of the fair market value of the common stock on the offering date or the purchase date, as defined in the Purchase Plan. Contributions are made through monthly payroll deductions of not less than 1% or more than 10% of cash compensation paid in the month. The Purchase Plan is administered by a committee of at least three directors appointed by the board of directors. At December 31, 2023, there were 546,264 shares available for issuance under this Purchase Plan. On March 30, 2022, the Company's board of directors authorized a stock repurchase plan that permits the repurchase of up to $50.0 million of the Company's common stock. During 2022, the Company repurchased and retired 625,710 common shares at an average price of $39.93 per share for the total cost of $25.0 million. The Company did not repurchase any shares of its common stock during the year ended December 31, 2023. Under the current authorization, common stock with a total value of up to $25.0 million remains available to be repurchased. The Company has a dividend reinvestment plan that is sponsored and administered by Computershare as independent agent, which enables current shareholders as well as first-time buyers to purchase and sell common stock of Sandy Spring Bancorp, Inc. directly through Computershare. Participants may reinvest cash dividends and make periodic supplemental cash payments to purchase additional shares. Bank and bank holding company regulations, as well as Maryland law, impose certain restrictions on dividend payments by the Bank, as well as restrictions on extensions of credit and transfers of assets between the Bank and Bancorp. At December 31, 2023, the Bank could have paid additional dividends of $213.8 million to its parent company without regulatory approval. There were no loans outstanding between the Bank and Bancorp at December 31, 2023 and 2022, respectively.

Share-Based Payment Arrangement [Abstract]
SHARE BASED COMPENSATION	SHARE BASED COMPENSATION The Company’s 2015 Omnibus Incentive Plan ("Omnibus Incentive Plan") was approved on May 6, 2015 and provides for the granting of incentive stock options, non-qualifying stock options, stock appreciation rights, restricted stock grants, restricted stock units and performance share units to selected directors and employees on a periodic basis at the discretion of the Company’s Board of Directors. The Omnibus Incentive Plan authorizes the issuance of up to 1,500,000 shares of common stock, of which 321,495 are available for issuance at December 31, 2023, has a term of 10 years, and is administered by a committee of at least three directors appointed by the Board of Directors. Options granted under the plan have an exercise price which may not be less than 100% of the fair market value of the common stock on the date of the grant and must be exercised within seven The value associated with the grant of restricted stock awards ("RSAs") and restricted share units ("RSUs") is determined by multiplying the fair market value of the Company's common stock on the grant date by the number of shares awarded. Holders of RSAs have the right to vote and receive cash dividends for the unvested RSAs. Non-vested RSAs are considered participating securities that have an immaterial impact on the computation of earnings per share. Holders of RSUs receive cash dividends on the vesting date and these units are not considered participating securities in the earnings per share calculation. Starting in 2022, grants of RSUs allow continued vesting following a qualified retirement. Any non-vested shares are subject to forfeiture upon termination of employment. Performance restricted stock units ("PRSUs") are subject to the Company's achievement of specified performance criteria over a three -year The Company stopped granting stock options in 2019. There was no unrecognized compensation cost related to stock options at December 31, 2023. The intrinsic value for the stock options exercised was $0.7 million, $0.3 million, and $8.0 million in the years ended December 31, 2023, 2022 and 2021, respectively. All stock compensation expense is recognized on a straight-line basis over the vesting period of the respective restricted stock, restricted stock unit grants or performance share units. Compensation expense associated with PRSUs is variable in nature based on the probability of achieving specific criteria. Compensation expense of $7.6 million, $7.9 million, and $5.3 million was recognized for the years ended December 31, 2023, 2022 and 2021, respectively, related to RSAs, RSUs and PRSUs. The total of unrecognized compensation cost related to RSAs, RSUs and PRSUs was approximately $5.8 million at December 31, 2023. That cost is expected to be recognized over a weighted average period of approximately 1.7 years. During the year ended December 31, 2023, the Company granted 282,503 RSUs and PRSUs under the Omnibus Incentive Plan, of which 63,867 are PRSUs subject to achievement of certain performance conditions measured over a three-year performance period and 218,636 are RSUs subject to a three-year vesting schedule. The Company did not grant any stock options under the Omnibus Incentive Plan during the year ended December 31, 2023.

PENSION, PROFIT SHARING, AND OTHER EMPLOYEE BENEFIT PLANS	PENSION, PROFIT SHARING, AND OTHER EMPLOYEE BENEFIT PLANS Defined Benefit Pension Plan Prior to September 30, 2023, the Company has maintained a qualified noncontributory, defined benefit pension plan (the “Plan”). On March 30, 2022, the Board of Directors approved the termination of the Pension Plan to be effective of June 30, 2022. The Company executed plan amendments regarding the Plan termination and received a determination letter from the Internal Revenue Service (“IRS”) as to the tax-qualified status of the Plan at the time of termination. The Company also filed appropriate notices and documents related to the Plan’s termination and wind-down with the Pension Benefit Guaranty Corporation (“PBGC”). Plan participants made elections for lump-sum distributions or annuity benefits. Both lump-sum distributions and transfer of annuity benefits to a highly-rated insurance company were completed in August 2023. In order to fully fund the Plan, the Company made a $1.3 million cash contribution. As a result of the pension termination, the Company incurred a one-time settlement expense of $8.2 million, which was recognized in salaries and employee benefits expense. The Pension Plan’s funded status at December 31 is as follows: (In thousands) 2023 2022 Reconciliation of Projected Benefit Obligation: Projected obligation at January 1 $ 35,539 $ 48,079 Interest cost 1,021 1,301 Actuarial (gain)/ loss (1,726) 376 Benefit payments (1,102) (2,106) Increase/ (decrease) related to change in assumptions — (12,111) Annuity Purchase (33,732) — Projected obligation at December 31 — 35,539 Reconciliation of Fair Value of Plan Assets: Fair value of plan assets at January 1 32,287 45,207 Actual return on plan assets 1,197 (10,814) Employer contributions 1,350 — Benefit payments (1,102) (2,106) Annuity Purchase (33,732) — Fair value of plan assets at December 31 $ — $ 32,287 Funded status at December 31 $ — $ (3,252) Accumulated benefit obligation at December 31 $ — $ 35,539 Unrecognized net actuarial loss $ — $ 10,736 Net periodic pension cost not yet recognized $ — $ 10,736 Weighted average assumptions used to determine benefit obligations at December 31 are presented in the following table: 2023 2022 2021 Discount rate N/A 5.10% 2.80% Rate of compensation increase N/A N/A N/A The components of net periodic benefit cost for the years ended December 31 are presented in the following table: (In thousands) 2023 2022 2021 Interest cost on projected benefit obligation $ 1,021 $ 1,301 $ 1,269 Expected return on plan assets (870) (1,410) (1,247) Recognized net actuarial loss 526 783 909 Settlement charge 8,157 — 560 Other 113 — — Net periodic benefit cost $ 8,947 $ 674 $ 1,491 Components of the net periodic benefit cost are recorded in salaries and employee benefits expense Weighted average assumptions used to determine net periodic benefit cost for years ended December 31 are presented in the following table: 2023 2022 2021 Discount rate 5.10% 2.80% 2.50% Expected return on plan assets 5.25% 3.75% 3.25% Rate of compensation increase N/A N/A N/A Sandy Spring Bank 401(k) Plan The Sandy Spring Bank 401(k) Plan (“the 401(k)”) is voluntary and covers all eligible employees after 90 days of service. The 401(k) provides that employees contributing to the 401(k) receive a matching contribution of 100% of the first 4% of compensation and 50% of the next 2% of compensation subject to employee contribution limitations. The Company matching contribution vests immediately. The 401(k) permits employees to purchase shares of the Company’s common stock with their 401(k) contributions, Company match, and other contributions under the 401(k). The Company’s matching contribution to the 401(k), which is included in salaries and employee benefits in non-interest expenses in the Consolidated Statements of Income, totaled $6.3 million, $5.9 million, and $6.0 million in 2023, 2022 and 2021, respectively. Deferred Compensation Plans The Executive Incentive Retirement Plan ("Executive Plan") is a non-qualified deferred compensation plan that provides for contributions to be made to the participants’ plan accounts based on the attainment of a level of financial performance determined annually by the board of directors. The Company ceased making contributions to the Executive Plan after adoption of the Non-Qualified Deferred Compensation Plan (“NQDC Plan”) in late 2021. The NQDC Plan provides participants with the option to defer receipt of a portion of their base salary and annual cash incentives. Participant contributions are fully vested at all times. At its sole discretion, the Company may credit participant accounts with company contributions. In 2023, executive officers were selected by the board of directors for contributions to be made to their plan accounts based on the attainment of a level of financial performance compared to a selected group of peer banks. Benefit costs related to the Executive Plan and NQDC Plan included in salaries and employee benefits in non-interest expenses in the Consolidated Statements of Income for 2023, 2022 and 2021 were $0.4 million, $0.7 million, and $0.7 million, respectively.

The Company is subject to U.S. federal income tax and income tax in various state jurisdictions. All tax years ending after December 31, 2019 are open to examination. Temporary differences between the amounts reported in the financial statements and the tax bases of assets and liabilities result in deferred taxes. Deferred tax assets and liabilities, shown as the sum of the appropriate tax effect for each significant type of temporary difference, are presented in the following table at December 31 for the years indicated: (In thousands) 2023 2022 Deferred tax assets: Allowance for credit losses $ 30,663 $ 34,703 Lease liability 12,262 14,692 Employee benefits 6,115 8,247 Unrealized losses on pension plan — 2,735 Deferred loan fees and costs 2,222 3,003 Equity based compensation 2,401 2,327 Unrealized losses on investments available-for-sale 33,087 42,362 Losses on other real estate owned — 27 Loan and deposit premium/discount 139 205 Reserve for recourse loans and unfunded commitments 1,225 2,169 Net operating loss carryforward 4,195 2,985 Other 157 240 Gross deferred tax assets 92,466 113,695 Valuation allowance (4,195) (3,124) Net deferred tax asset 88,271 110,571 Deferred tax liabilities: Right of use asset (10,292) (12,511) Pension plan costs — (1,906) Depreciation (4,559) (4,203) Intangible assets (2,128) (2,709) Bond accretion (542) (289) Fair value acquisition adjustments (609) (660) Other (486) (738) Gross deferred tax liabilities (18,616) (23,016) Net deferred tax asset $ 69,655 $ 87,555 The Company has approximately $38.2 million of state net operating loss carryover which begins to expire in 2032 and $26.1 million of state carryforward of disallowed net business excess interest expense. The Company believes that it is more likely than not that the future benefit from the state net operating loss and disallowed net business excess interest expense carryover will not be realized. As such, there is a valuation allowance on the deferred tax assets of the jurisdictions in which those net operating losses and disallowed net business excess interest expense relate.

ACCUMULATED OTHER COMPREHENSIVE INCOME/ (LOSS)	ACCUMULATED OTHER COMPREHENSIVE INCOME/ (LOSS) Comprehensive income/ (loss) is defined as net income plus transactions and other occurrences that are the result of non-owner changes in equity. For financial statements presented for the Company, non-owner changes in equity are comprised of unrealized gains or losses on investments available-for-sale and held-to-maturity, and any pension liability adjustments. These adjustments do not have an impact on the Company’s net income. Realized gains and losses on available-for-sale debt securities, and the amortization of unrealized losses on held-to-maturity debt securities and net periodic benefit cost impact the Company's net income as discussed in the following tables.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVES	DERIVATIVES Customer Interest Rate Swaps The Company has entered into interest rate swaps (“swaps”) with qualifying commercial banking customers to facilitate their risk management strategies and financing needs. These swaps provide customers with the ability to convert variable rates into fixed rates. They are economically hedged by offsetting interest rate swaps that the Company executes with derivative counterparties in order to offset its exposure on the fixed components of the customers' swaps. Swaps qualify as derivatives, but are not designated as hedging instruments. Fair values of the swaps are carried as both gross assets and gross liabilities in other assets and other liabilities, respectively, in the Consolidated Statements of Condition. The associated changes in fair values of gross assets and gross liabilities net to zero in the Consolidated Statements of Income. Mortgage Banking Derivatives The Company enters into interest rate lock commitments, which are commitments to originate loans where the interest rate on the loan is determined prior to funding and the customers have locked into that interest rate. The loans are sold to the secondary market on either a mandatory or best efforts basis. Loans sold on a mandatory basis are not committed to an investor until the loan is closed with the borrower. The Company enters into forward to-be-announced (“TBA”) sales contracts to manage the interest rate risk between the interest rate lock commitment and the funding of those loans. Loans sold on a best efforts basis are committed to an investor simultaneous to the interest rate lock commitment with the borrower, and as a result, the Company does not enter into a separate forward TBA contract to offset the fair value risk as the investor accepts such risk. Interest rate lock commitments and commitments to deliver loans to investors are considered derivatives but are not designated as hedging instruments. Fair Values of Derivative Instruments on the Balance Sheet Derivatives are carried at fair value and are classified under other assets and other liabilities in the Consolidated Statements of Condition. Changes in fair value are recognized in earnings. None of the Company's derivatives are designated in a qualifying hedging relationship.

FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK	FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK In the normal course of business, the Company has various outstanding credit commitments that are not reflected in the financial statements. These commitments are made to satisfy the financing needs of the Company's clients. The associated credit risk is controlled by subjecting such activity to the same credit and quality controls as exist for the Company's lending and investing activities. The commitments involve diverse business and consumer customers and are generally well collateralized. Collateral held varies, but may include residential real estate, commercial real estate, property and equipment, inventory and accounts receivable. Commitments do not necessarily represent future cash requirements as a portion of the commitments have some reduced likelihood of being exercised. Additionally, many of the commitments are subject to annual reviews, material change clauses or requirements for inspections prior to draw funding that could result in a curtailment of the funding commitments. A summary of the financial instruments with off-balance sheet credit risk is as follows at December 31 for the years indicated: (In thousands) 2023 2022 Commercial real estate development and construction $ 572,540 $ 887,154 Residential real estate-development and construction 713,903 798,607 Real estate-residential mortgage 16,608 21,118 Lines of credit, principally home equity and business lines 2,405,150 2,397,533 Standby letters of credit 71,817 77,424 Total commitments to extend credit and available credit lines $ 3,780,018 $ 4,181,836

FAIR VALUE

FAIR VALUE	12 Months Ended

Fair Value Disclosures [Abstract]
FAIR VALUE	FAIR VALUE GAAP provides entities the option to measure eligible financial assets, financial liabilities and commitments at fair value (i.e. the fair value option), on an instrument-by-instrument basis, that are otherwise not permitted to be accounted for at fair value under other accounting standards. The election to use the fair value option is available when an entity first recognizes a financial asset or financial liability or upon entering into a commitment. Subsequent changes in fair value must be recorded in earnings. The Company applies the fair value option on residential mortgage loans held for sale. The fair value option on residential mortgage loans allows the recognition of gains on sale of mortgage loans to more accurately reflect the timing and economics of the transaction. The standard for fair value measurement establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are described below. Basis of Fair Value Measurement: Level 1 - Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. Level 2 - Quoted prices in markets that are not active, or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability. Level 3 - Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e. supported by little or no market activity). A financial instrument’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. Changes to interest rates may result in changes in the cash flows due to prepayments or extinguishments. Accordingly, this could result in higher or lower measurements of the fair values. Assets and Liabilities Residential mortgage loans held for sale Residential mortgage loans held for sale are valued based on quotations from the secondary market for similar instruments and are classified as Level 2 in the fair value hierarchy. Investments available-for-sale U.S. treasuries and government agencies securities and mortgage-backed and asset-backed securities Valuations are based on active market data and use of evaluated broker pricing models that vary based by asset class and includes available trade, bid, and other market information. Generally, the methodology includes broker quotes, proprietary models, descriptive terms, and databases coupled with extensive quality control programs. Quality control evaluation processes use available market, credit and deal level information to support the evaluation of the security. Additionally, proprietary models and pricing systems, mathematical tools, actual transacted prices, integration of market developments and experienced evaluators are used to determine the value of a security based on a hierarchy of market information regarding a security or securities with similar characteristics. The Company does not adjust the quoted price for such securities. Such instruments are classified within Level 2 in the fair value hierarchy. State and municipal securities The Company primarily uses prices obtained from third-party pricing services to determine the fair value of state and municipal securities. The Company independently evaluates and corroborates the fair value received from pricing services through various methods and techniques, including references to dealer or other market quotes, by reviewing valuations of comparable instruments, and by comparing the prices realized on the sale of similar securities. Such securities are classified within Level 2 in the fair value hierarchy. Interest rate swap agreements Interest rate swap agreements are measured by alternative pricing sources using a discounted cash flow method that incorporates current market interest rates. Based on the complex nature of interest rate swap agreements, the markets these instruments trade in are not as efficient and are less liquid than that of the more mature Level 1 markets. These characteristics classify interest rate swap agreements as Level 2 in the fair value hierarchy. Assets and Liabilities Measured at Fair Value on a Recurring Basis The following tables set forth the Company’s financial assets and liabilities at the December 31 for the years indicated that were accounted for or disclosed at fair value. Assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement: 2023 (In thousands) Quoted Prices in Significant Other Significant Total Assets Residential mortgage loans held for sale (1) $ — $ 10,836 $ — $ 10,836 Available-for-sale debt securities: U.S. government agencies — 96,927 — 96,927 State and municipal — 268,214 — 268,214 Mortgage-backed and asset-backed — 737,540 — 737,540 Total available-for-sale debt securities — 1,102,681 — 1,102,681 Interest rate swap agreements — 15,867 — 15,867 Total assets $ — $ 1,129,384 $ — $ 1,129,384 Liabilities Interest rate swap agreements $ — $ (15,867) $ — $ (15,867) Total liabilities $ — $ (15,867) $ — $ (15,867) (1) The outstanding principal balance for residential loans held for sale as of December 31, 2023 was $10.5 million. 2022 (In thousands) Quoted Prices in Significant Other Significant Total Assets Residential mortgage loans held for sale (1) $ — $ 11,706 $ — $ 11,706 Investments available-for-sale: U.S. government agencies — 93,622 — 93,622 State and municipal — 265,997 — 265,997 Mortgage-backed and asset-backed — 854,919 — 854,919 Total available-for-sale securities — 1,214,538 — 1,214,538 Interest rate swap agreements — 18,596 — 18,596 Total assets $ — $ 1,244,840 $ — $ 1,244,840 Liabilities Interest rate swap agreements $ — $ (18,596) $ — $ (18,596) Total liabilities $ — $ (18,596) $ — $ (18,596) (1) The outstanding principal balance for residential loans held for sale as of December 31, 2022 was $11.3 million. Assets Measured at Fair Value on a Non-recurring Basis The following tables set forth the Company’s financial assets subject to fair value adjustments on a non-recurring basis at December 31 for the year indicated that are valued at the lower of cost or market. Assets are classified in their entirety based on the lowest level of input that is significant to the fair value measurement: 2023 (In thousands) Quoted Prices in Significant Other Significant Total Total Losses Loans (1) $ — $ — $ — $ — $ — Other real estate owned — — $ — $ — $ — Total $ — $ — $ — $ — $ — (1) Represent outstanding amount of collateral-dependent non-accrual loans that were written down to the fair value of the underlying collateral. Fair values are determined using actual market prices (Level 2), independent third-party valuations and borrower records, discounted as appropriate (Level 3). 2022 (In thousands) Quoted Prices in Significant Other Significant Total Total Losses Loans (1) $ — $ — $ 190 $ 190 $ (384) Other real estate owned — — 645 645 (105) Total $ — $ — $ 835 $ 835 $ (489) (1) Represent outstanding amount of collateral-dependent non-accrual loans that were written down to the fair value of the underlying collateral. Fair values are determined using actual market prices (Level 2), independent third-party valuations and borrower records, discounted as appropriate (Level 3). At December 31, 2023, loans totaling $88.2 million were written down to fair value of $64.2 million as a result of individual credit loss allowances of $24.0 million associated with the collateral dependent non-accrual loans which was included in the allowance for credit losses. Loans totaling $26.2 million were written down to fair value of $19.3 million at December 31, 2022 as a result of individual credit loss allowances of $6.9 million associated with the collateral dependent non-accrual loans. Fair value of the collateral dependent loans is measured based on the loan’s observable market price or the fair value of the collateral (less estimated selling costs). Collateral may be real estate and/or business assets such as equipment, inventory and/or accounts receivable. The value of business equipment, inventory and accounts receivable collateral is based on net book value on the business’ financial statements and, if necessary, discounted based on management’s review and analysis. Appraised and reported values may be discounted based on management’s historical experience, changes in market conditions from the time of valuation, and/or management’s expertise and knowledge of the client and client’s business. Collateral dependent loans are reviewed and evaluated on at least a quarterly basis for additional individual reserve and adjusted accordingly, based on the factors identified above. OREO is adjusted to fair value upon transfer of the loans to OREO. Subsequently, OREO is carried at the lower of carrying value or fair value, less cost of disposal. The estimated fair value for OREO included in Level 3 is determined by independent market based appraisals and other available market information, less cost of disposal, that may be reduced further based on market expectations or an executed sales agreement. If the fair value of the collateral deteriorates subsequent to initial recognition, the Company records the OREO as a non-recurring Level 3 adjustment. Valuation techniques are consistent with those techniques applied in prior periods. Fair Value of Financial Instruments The Company discloses fair value information, based on the exit price notion, of financial instruments that are not measured at fair value in the financial statements. Fair value is the amount at which a financial instrument could be exchanged in a current transaction between willing parties, other than in a forced sale or liquidation, and is best evidenced by a quoted market price, if one exists. Quoted market prices, where available, are shown as estimates of fair market values. Because no quoted market prices are available for a significant portion of the Company's financial instruments, the fair value of such instruments has been derived based on the amount and timing of future cash flows and estimated discount rates based on observable inputs (“Level 2”) or unobservable inputs (“Level 3”). Present value techniques used in estimating the fair value of many of the Company's financial instruments are significantly affected by the assumptions used. In that regard, the derived fair value estimates cannot be substantiated by comparison to independent markets and, in many cases, could not be realized in immediate cash settlement of the instrument. Additionally, the accompanying estimates of fair values are only representative of the fair values of the individual financial assets and liabilities, and should not be considered an indication of the fair value of the Company. Management utilizes internal models used in asset liability management to determine the fair values disclosed below. Other investments include FRB and FHLB stock, whose carrying amounts approximate fair values based on the redemption provisions of each entity. The carrying amounts and fair values of the Company’s financial instruments at December 31 for the year indicated are presented in the following table: Fair Value Measurements 2023 Quoted Prices in Significant Other Significant (In thousands) Carrying Estimated Financial assets: Cash and cash equivalents $ 545,898 $ 545,898 $ 545,898 $ — $ — Residential mortgage loans held for sale 10,836 10,836 — 10,836 — Available-for-sale debt securities 1,102,681 1,102,681 — 1,102,681 — Held-to-maturity debt securities 236,165 200,411 — 200,411 — Other investments 75,607 75,607 — 75,607 — Loans, net of allowance 11,246,124 10,476,059 — — 10,476,059 Interest rate swap agreements 15,867 15,867 — 15,867 — Accrued interest receivable 46,583 46,583 46,583 — — Bank owned life insurance 158,921 158,921 — 158,921 — Financial liabilities: Time deposits $ 2,714,555 $ 2,704,013 $ — $ 2,704,013 $ — Other deposits 8,281,983 8,281,983 8,281,983 — — Securities sold under retail repurchase agreements and federal funds purchased 375,032 375,032 — 375,032 — Advances from FHLB 550,000 547,271 — 547,271 — Subordinated debt 370,803 348,185 — — 348,185 Interest rate swap agreements 15,867 15,867 — 15,867 — Accrued interest payable 30,367 30,367 30,367 — — Fair Value Measurements 2022 Quoted Prices in Significant Other Significant (In thousands) Carrying Estimated Financial assets: Cash and cash equivalents $ 192,232 $ 192,232 $ 192,232 $ — $ — Residential mortgage loans held for sale 11,706 11,706 — 11,706 — Investments available-for-sale 1,214,538 1,214,538 — 1,214,538 — Held-to-maturity debt securities 259,452 220,123 — 220,123 — Other investments 69,218 69,218 — 69,218 — Loans, net of allowance 11,260,464 11,020,992 — — 11,020,992 Interest rate swap agreements 18,596 18,596 — 18,596 — Accrued interest receivable 41,172 41,172 41,172 — — Bank owned life insurance 153,016 153,016 — 153,016 — Financial liabilities: Time deposits $ 2,118,262 $ 2,082,319 $ — $ 2,082,319 $ — Other deposits 8,835,159 8,835,159 8,835,159 — — Securities sold under retail repurchase agreements and federal funds purchased 321,967 321,967 — 321,967 — Advances from FHLB 550,000 549,530 — 549,530 — Subordinated debt 370,205 332,470 — — 332,470 Interest rate swap agreements 18,596 18,596 — 18,596 — Accrued interest payable 10,867 10,867 10,867 — —

REGULATORY MATTERS	12 Months Ended

Banking and Thrift, Interest [Abstract]
REGULATORY MATTERS	REGULATORY MATTERS The Company and the Bank are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company's and the Bank's financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Bank must meet specific capital guidelines that involve quantitative measures of the Bank's assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices. The Company and the Bank's capital amounts and classifications are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors. Quantitative measures established and defined by regulation to ensure capital adequacy require the Company and the Bank to maintain minimum amounts and ratios of Total, Tier 1 and Common Equity Tier 1 capital to risk-weighted assets, and of Tier 1 capital to average assets. As of December 31, 2023 and 2022, the capital levels of the Company and the Bank substantially exceeded all applicable capital adequacy requirements. As of December 31, 2023, the most recent notification from the Bank’s primary regulator categorized the Bank as well capitalized under the regulatory framework for prompt corrective action. To be categorized as well capitalized the Bank must maintain minimum Total risk-based, Tier 1 risk-based, Common Equity Tier 1 risk-based, and Tier 1 leverage ratios as set forth in the following table. There are no conditions or events since that notification that management believes have changed the Bank's category. The Company's and the Bank's actual capital amounts and ratios at December 31 for the years indicated are presented in the following table: Actual For Capital To be Well (Dollars in thousands) Amount Ratio Amount Ratio Amount Ratio As of December 31, 2023 Tier 1 Leverage: Company $ 1,303,684 9.51 % $ 548,345 4.00 % N/A N/A Sandy Spring Bank $ 1,548,387 11.30 % $ 548,198 4.00 % $ 685,247 5.00 % Common Equity Tier 1 Capital to risk- weighted assets: Company $ 1,303,684 10.90 % $ 538,445 4.50 % N/A N/A Sandy Spring Bank $ 1,548,387 12.95 % $ 538,227 4.50 % $ 777,440 6.50 % Tier 1 Capital to risk-weighted assets: Company $ 1,303,684 10.90 % $ 717,926 6.00 % N/A N/A Sandy Spring Bank $ 1,548,387 12.95 % $ 717,637 6.00 % $ 956,849 8.00 % Total Capital to risk-weighted assets: Company $ 1,785,347 14.92 % $ 957,235 8.00 % N/A N/A Sandy Spring Bank $ 1,655,050 13.84 % $ 956,849 8.00 % $ 1,196,061 10.00 % As of December 31, 2022 Tier 1 Leverage: Company $ 1,250,218 9.33 % $ 536,159 4.00 % N/A N/A Sandy Spring Bank $ 1,535,674 11.46 % $ 536,016 4.00 % $ 670,020 5.00 % Common Equity Tier 1 Capital to risk- weighted assets: Company $ 1,250,218 10.23 % $ 549,992 4.50 % N/A N/A Sandy Spring Bank $ 1,535,674 12.57 % $ 549,681 4.50 % $ 793,984 6.50 % Tier 1 Capital to risk-weighted assets: Company $ 1,250,218 10.23 % $ 733,323 6.00 % N/A N/A Sandy Spring Bank $ 1,535,674 12.57 % $ 732,909 6.00 % $ 977,212 8.00 % Total Capital to risk-weighted assets: Company $ 1,735,342 14.20 % $ 977,764 8.00 % N/A N/A Sandy Spring Bank $ 1,645,799 13.47 % $ 977,212 8.00 % $ 1,221,514 10.00 %

SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended

Accounting Policies [Abstract]
Nature of Operations	Nature of Operations Sandy Spring Bancorp, Inc. ("Bancorp" or, together with its subsidiaries, the "Company"), a Maryland corporation, is the bank holding company for Sandy Spring Bank (the “Bank”). Independent and community-oriented, the Bank offers a broad range of commercial banking, retail banking, mortgage services and trust services throughout central Maryland, northern Virginia, and the greater Washington, D.C. market. The Bank also offers a comprehensive menu of wealth management services through its subsidiaries, West Financial Services, Inc. (“West Financial”) and SSB Wealth Management, Inc. (d/b/a Rembert Pendleton Jackson, "RPJ”) .
Basis of Presentation	Basis of Presentation The accounting and reporting policies of the Company conform to accounting principles generally accepted in the United States of America (“GAAP”) and prevailing practices within the financial services industry for financial information. The following summary of significant accounting policies of the Company is presented to assist the reader in understanding the financial and other data presented in this report. Certain prior period amounts have been reclassified to conform to the current period presentation. Such reclassifications had no impact on the Company’s net income and shareholders’ equity. The Company has evaluated subsequent events through the date of the issuance of its financial statements.
Principles of Consolidation	Principles of Consolidation The consolidated financial statements include the accounts of the Company and its wholly owned subsidiary, Sandy Spring Bank and its subsidiaries. Consolidation has resulted in the elimination of all significant intercompany accounts and transactions.
Use of Estimates	Use of Estimates The preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements, in addition to affecting the reported amounts of revenues earned and expenses incurred during the reporting period. Actual results could differ from those estimates. Estimates that could change significantly relate to the provision for credit losses and the related allowance, potential impairment of goodwill or other intangible assets, valuation of investment securities and the determination of whether available-for-sale debt securities with fair values less than amortized costs are impaired and require an allowance for credit losses, valuation of other real estate owned, valuation of share based compensation, the assessment that a liability should be recognized with respect to any matters under litigation, the calculation of current and deferred income taxes, and the actuarial projections related to pension expense and the related liability.
Assets Under Management	Assets Under Management Assets held for others under fiduciary and agency relationships are not assets of the Company or its subsidiaries and are not included in the accompanying Consolidated Statements of Condition. Trust department income and investment management fees are presented on an accrual basis.
Cash Flows	Cash Flows For purposes of reporting cash flows, cash and cash equivalents include cash and due from banks, federal funds sold and interest-bearing deposits with banks (items with an original maturity of three months or less).
Revenue from Contract with Customers	Revenue from Contracts with Customers The Company’s revenue includes net interest income on financial instruments and non-interest income. Specific categories of revenue are presented in the Consolidated Statements of Income. Most of the Company’s revenue is not within the scope of Accounting Standard Codification (“ASC”) 606 – Revenue from Contracts with Customers. For revenue within the scope of ASC 606, the Company provides services to customers and has related performance obligations. The revenue from such services is recognized upon satisfaction of all contractual performance obligations. The following discusses key revenue streams within the scope of revenue recognition guidance. West Financial and RPJ provide comprehensive investment management and financial planning services. Wealth management income is comprised of income for providing trust, estate and investment management services. Trust services include acting as a trustee for corporate or personal trusts. Investment management services include investment management, record-keeping and reporting of security portfolios. Fees for these services are recognized based on a contractually-agreed fixed percentage applied to net assets under management at the end of each reporting period. The Company does not charge/recognize any performance-based fees. Prior to the sale of its assets in June 2022, Sandy Spring Insurance Corporation performed the function of an insurance intermediary by introducing the policyholder and insurer and was compensated by a commission fee for placement of an insurance policy. Sandy Spring Insurance did not provide any captive management services or any claim handling services. Commission fees were set as a percentage of the premium for the insurance policy for which Sandy Spring Insurance was a producer. Sandy Spring Insurance recognized revenue when the insurance policy was contractually agreed to by the insurer and policyholder (at transaction date). Service charges on deposit accounts are earned on depository accounts for consumer and commercial account holders and include fees for account and overdraft services. Account services include fees for event-driven services and periodic account maintenance activities. An obligation for event-driven services is satisfied at the time of the event when service is delivered and revenue recognized as earned. Obligation for maintenance activities is satisfied over the course of each month and revenue is recognized at month end. The overdraft services obligation is satisfied at the time of the overdraft and revenue is recognized as earned.
Residential Mortgage Loans Held For Sale	Residential Mortgage Loans Held for Sale The Company engages in sales of residential mortgage loans originated by the Bank. Loans held for sale are carried at fair value. Fair value is derived from secondary market quotations for similar instruments. The Company measures residential mortgage loans at fair value when the Company first recognizes the loan (i.e., the fair value option). Changes in fair value of these loans are recorded in earnings as a component of mortgage banking activities in non-interest income in the Consolidated Statements of Income. The Company's current practice is to sell the majority of such loans on a servicing released basis. Any retained servicing assets are amortized in proportion to their net servicing fee income over the life of the respective loans. Servicing assets are evaluated for impairment on a periodic basis.
Investments Held-to-maturity	Investments Held-to-maturity Debt securities that are purchased with the positive intent and ability to be held until their maturity are classified as held-to-maturity (“HTM”). HTM debt securities are recorded at cost adjusted for amortization of premiums and accretion of discounts. Transfers of debt securities from available-for-sale ("AFS") category to HTM category are made at fair value as of the transfer date. The unrealized gain or loss at the date of transfer continues to be reported in accumulated other comprehensive income and in the carrying amount of the HTM securities. Both amounts are amortized over the remaining life of the security as a yield adjustment in interest income and effectively offset each other.
Investments Available-for-sale	Investments Available-for-Sale Debt securities not classified as held-to-maturity or trading are classified as securities available-for-sale. Securities available-for-sale are acquired as part of the Company's asset/liability management strategy and may be sold in response to changes in interest rates, loan demand, changes in prepayment risk or other factors. Securities available-for-sale are carried at fair value, with unrealized gains or losses based on the difference between amortized cost and fair value, reported net of deferred tax, as accumulated other comprehensive income/ (loss), a separate component of stockholders' equity. The amortized cost of securities available-for-sale are adjusted for premium amortization and discount accretion. Premium is amortized to the earliest call date and discount accreted to the maturity date using the effective interest method. Realized gains and losses on security sales or maturities, using the specific identification method, are included as a separate component of non-interest income. Related interest and dividend income are included in interest income. Declines in the fair value of individual available-for-sale securities below their amortized cost due to credit-related factors are recognized as an allowance for credit losses. Credit-related factors affecting the determination of whether impairment has occurred include a downgrading of the security below investment grade by a rating agency or due to potential default, a significant deterioration in the financial condition of the issuer, increase in entity-specific credit spreads. Additionally, on any available-for-sale securities with unrealized losses, the Company evaluates its intent and ability to hold the investment for a period of time sufficient to allow for any anticipated recovery in fair value.
Other Investments	Other Investments Equity securities include Federal Reserve Bank stock, Federal Home Loan Bank of Atlanta ("FHLB") stock and other equities that are considered restricted as to marketability and recorded at cost. As these securities do not have readily available market values, they are carried at cost and adjusted for any necessary impairments each reporting period.
Loan Financing Receivables	Loan Financing Receivables The Company’s financing receivables consist primarily of loans that are stated at their principal balance outstanding, net of any unearned income, acquisition fair value marks and deferred loan origination fees and costs. Interest income on loans is accrued at the contractual rate based on the principal balance outstanding. Loan origination fees, net of certain direct origination costs, are deferred and recognized as an adjustment of the related loan yield using the interest method. Loans are considered past due or delinquent when the principal or interest due in accordance with the contractual terms of the loan agreement or any portion thereof remains unpaid after the due date of the scheduled payment. Immaterial shortfalls in payment amounts do not necessarily result in a loan being considered delinquent or past due. If any payments are past due and subsequent payments are resumed without payment of the delinquent amount, the loan shall continue to be considered past due. Whenever any loan is reported delinquent on a principal or interest payment or portion thereof, the amount reported as delinquent is the outstanding principal balance of the loan. Loans, except for consumer installment loans, are placed into non-accrual status when any portion of the loan principal or interest becomes 90 days past due. Management may determine that certain circumstances warrant earlier discontinuance of interest accruals on specific loans if an evaluation of other relevant factors (such as bankruptcy, interruption of cash flows, etc.) indicates collection of amounts contractually due is unlikely. These loans are considered, collectively, to be non-performing loans. Consumer installment loans that are not secured by real estate are not placed on non-accrual, but are charged down to their net realizable value when they are four months past due. Loans designated as non-accrual have all previously accrued but unpaid interest reversed. Interest income is not recognized on non-accrual loans. All payments received on non-accrual loans are applied using a cost-recovery method to reduce the outstanding principal balance until the loan returns to accrual status. Loans may be returned to accrual status when all principal and interest amounts contractually due are brought current and future payments are reasonably assured. On January 1, 2023, the Company adopted provisions of ASU 2022-02, "Financial Instruments - Credit Losses (Topic 326)", which eliminated accounting guidance for troubled debt restructurings ("TDRs") by creditors and expanded disclosures about modifications. Prior to the effective adoption date, the Company considered loans to be TDRs if their terms were restructured (e.g., interest rates, loan maturity date, payment and amortization period, etc.) in circumstances that provided a payment concession to a borrower experiencing financial difficulty. Loans could be removed from a TDR category if the borrower no longer experienced financial difficulty, a re-underwriting event took place, and the revised loan terms of the subsequent restructuring agreement were considered to be consistent with terms that could be obtained in the market for loans with comparable credit risk. Subsequent to the effective adoption date of ASU 2022-02, the Company continues to offer modifications to certain borrowers experiencing financial difficulty, mainly in the form of interest rate concessions or term extensions, without classifying and accounting for them as TDRs.
Allowance for Credit Losses	Allowance for Credit Losses The allowance for credit losses (“allowance” or “ACL”) represents an amount which, in management's judgment, reflects the lifetime expected losses that may be sustained on outstanding loans at the balance sheet date based on the evaluation of the size and current risk characteristics of the loan portfolio, past events, current conditions, reasonable and supportable forecasts of future economic conditions and prepayment experience. The allowance is measured and recorded upon the initial recognition of a financial asset. The allowance is reduced by charge-offs, net of recoveries of previous losses, and is increased or decreased by a provision or credit for credit losses, which is recorded as a current period expense. Determination of the appropriateness of the allowance is inherently complex and requires the use of significant and highly subjective estimates. The reasonableness of the allowance is reviewed by the Risk Committee of the Board of Directors and formally approved quarterly by that same committee of the Board. The Company’s methodology for estimating the allowance includes: (1) a collective quantified reserve that reflects the Company’s historical default and loss experience adjusted for expected economic conditions throughout a reasonable and supportable period and the Company’s prepayment and curtailment rates; (2) collective qualitative factors that consider the expected impact of certain factors not fully captured in the collective quantified reserve, including concentrations of the loan portfolio, expected changes to the economic forecasts, large relationships, early delinquencies, and factors related to credit administration, including, among others, loan-to-value ratios, borrowers’ risk rating and credit score migrations; and (3) individual allowances on collateral-dependent loans where borrowers are experiencing financial difficulty or when the Company determines that the foreclosure is probable. The Company excludes accrued interest from the measurement of the allowance as the Company has a non-accrual policy to reverse any accrued, uncollected interest income as loans are moved to non-accrual status. Loans are pooled into segments based on the similar risk characteristics of the underlying borrowers, in addition to consideration of collateral type, industry and business purpose of the loans. Portfolio segments used to estimate the allowance are the same as portfolio segments used for general credit risk management purposes. Refer to Note 4 for more details on the Company’s portfolio segments. The Company applies two calculation methodologies to estimate the collective quantified component of the allowance: discounted cash flows method and weighted average remaining life method. Allowance estimates on commercial acquisition, development and construction (“AD&C”) and residential construction segments are based on the weighted average remaining life method. Allowance estimates on all other portfolio segments are based on the discounted cash flows method. Segments utilizing the discounted cash flows method are further sub-segmented into risk level pools, determined either by risk rating for commercial loans or Beacon Scores ranges for residential and consumer loans. To better manage risk and reasonably determine the sufficiency of reserves, this segregation allows the Company to monitor the allowance component applicable to higher risk loans separate from the remainder of the portfolio. Collective calculation methodologies utilize the Company’s historical default and loss experience adjusted for future economic forecasts. The reasonable and supportable forecast period represents a two-year economic outlook for the applicable economic variables. Following the end of the reasonable and supportable forecast period expected losses revert back to the historical mean over the next two years on a straight-line basis. Economic variables that have the most significant impact on the allowance include: unemployment rate, house price index and business bankruptcies. Contractual loan level cash flows within the discounted cash flows methodology are adjusted for the Company’s historical prepayment and curtailment rate experience. The individual reserve assessment is applied to collateral dependent loans where borrowers are experiencing financial difficulty or when the Company determines that a foreclosure is probable. The determination of the fair value of the collateral depends on whether a repayment of the loan is expected to be from the sale or the operation of the collateral. When a repayment is expected from the operation of the collateral, the Company uses the present value of expected cash flows from the operation of the collateral as the fair value. When the repayment of the loan is expected from the sale of the collateral the fair value of the collateral is based on an observable market price or the collateral’s appraised value, less estimated costs to sell. Third-party appraisals used in the individual reserve assessment are conducted at least annually with underlying assumptions that are reviewed by management. Third-party appraisals may be obtained on a more frequent basis if deemed necessary. Internal evaluations of collateral value are conducted quarterly to ensure any further deterioration of the collateral value is recognized on a timely basis. During the individual reserve assessment, management also considers the potential future changes in the value of the collateral over the remainder of the loan’s remaining life. The Company may receive updated appraisals which contradict the preliminary determination of fair value used to establish an individual allowance on a loan. In these instances the individual allowance is adjusted to reflect the Company’s evaluation of the updated appraised fair value. In the event a loss was previously confirmed and the loan was charged down to the estimated fair value based on a previous appraisal, the balance of partially charged-off loans are not subsequently increased, but could be further decreased depending on the direction of the change in fair value. Payments on fully or partially charged-off loans are accounted for under the cost-recovery method. Under this method, all payments received are applied on a cash basis to reduce the entire outstanding principal balance, then to recognize a recovery of all previously charged-off amounts before any interest income may be recognized. Based on the individual reserve assessment, if the Company determines that the fair value of the collateral is less than the amortized cost basis of the loan, an individual allowance will be established measured as the difference between the fair value of the collateral (less costs to sell) and the amortized cost basis of the loan. Once a loss has been confirmed, the loan is charged-down to its estimated fair value. Large groups of smaller non-accrual homogeneous loans are not individually evaluated for allowance and include residential permanent and construction mortgages and consumer installment loans. These portfolios are reserved for on a collective basis using historical loss rates of similar loans over the weighted average life of each pool. Unfunded lending commitments are reviewed to determine if they are considered unconditionally cancellable. The Company establishes reserves for unfunded commitments that do not meet that criteria as a liability in the Consolidated Statements of Condition. Changes to the liability are recorded through the provision for credit losses in the Consolidated Statements of Income. The establishment of the reserves for unfunded commitments considers both the likelihood that the funding will occur and an estimate of the expected credit losses over the life of the respective commitments. Management believes it uses relevant information available to make determinations about the allowance for credit losses and the reserve for unfunded commitments and that it has established both reserves in accordance with GAAP. However, the determination of the allowance requires significant judgment, and estimates of expected lifetime losses in the loan portfolio can vary significantly from the amounts actually observed. While management uses available information to recognize expected losses, future additions to the allowance may be necessary based on changes in the loans comprising the portfolio, changes in the current and forecasted economic conditions, changes to the interest rate environment which may directly impact prepayment and curtailment rate assumptions, and changes in the financial condition of borrowers.
Premises and Equipment	Premises and Equipment Premises and equipment are stated at cost, less accumulated depreciation and amortization, computed using the straight-line method. Premises and equipment are depreciated over the useful lives of the assets, which generally range from 3 to 10 years for furniture, fixtures and equipment, 3 to 5 years for computer software and hardware, and 10 to 40 years for buildings and building improvements. Leasehold improvements are amortized over the lesser of the lease term or the estimated useful lives of the improvements. The costs of major renewals and betterments are capitalized, while the costs of ordinary maintenance and repairs are included in non-interest expense.
Leases	Leases The Company determines if an arrangement is a lease at inception. All of the Company’s leases are currently classified as operating leases and are included in other assets and other liabilities on the Company’s Consolidated Statements of Condition. Periodic operating lease costs are recorded in occupancy expenses of premises on the Company's Consolidated Statements of Income. Right-of-use (“ROU”) assets represent the Company’s right to use an underlying asset for the lease term, and lease liabilities represent the Company’s obligation to make lease payments arising from the lease arrangements. Operating lease ROU assets and liabilities are recognized at the lease commencement date based on the present value of the expected future lease payments over the remaining lease term. In determining the present value of future lease payments, the Company uses its incremental borrowing rate based on the information available at the lease commencement date. The operating ROU assets are adjusted for any lease payments made at or before the lease commencement date, initial direct costs, any lease incentives received and, for acquired leases, any favorable or unfavorable fair value adjustments. The present value of the lease liability may include the impact of options to extend or terminate the lease when it is reasonably certain that the Company will exercise such options provided in the lease terms. Lease expense is recognized on a straight-line basis over the expected lease term. Lease agreements that include lease and non-lease components, such as common area maintenance charges, are accounted for separately.
Segment Reporting	Segment Reporting Operating segments are components of a business about which separate financial information is available and evaluated regularly by the chief operating decision maker in deciding how to allocate resources and assessing performance. The Bank is the Company’s only reportable operating segment upon which management makes decisions regarding how to allocate resources and assess performance. While the Company’s chief operating decision maker has some limited financial information about its various financial products and services, that information is not complete since it does not include a full allocation of revenue, costs, and capital from key corporate functions; therefore, the Company evaluates financial performance on a company-wide basis. Management continues to evaluate the Company's business units for separate reporting as facts and circumstances change.
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets Goodwill represents the excess purchase price paid over the fair value of the net assets acquired in a business combination. Goodwill is not amortized but is tested for impairment annually or more frequently if events or changes in circumstances indicate that the asset might be impaired. Impairment testing requires that the fair value of each of the Company’s reporting units be compared to the carrying amount of the reporting unit’s net assets, including goodwill. The Company’s reporting units were identified based upon an analysis of each of its individual operating segments. If the fair values of the reporting units exceed their book values, no write-down of recorded goodwill is required. If the fair value of a reporting unit is less than book value, an expense may be required to write-down the related goodwill to the proper carrying value. Any impairment would be realized through a reduction of goodwill or the intangible and an offsetting charge to non-interest expense. Accounting guidance provides the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. The Company assesses qualitative factors on a quarterly basis. Based on the assessment of these qualitative factors, if it is determined that it is more likely than not that the fair value of a reporting unit is not less than the carrying value, then performing the impairment process is not necessary. However, if it is determined that it is more likely than not that the carrying value exceeds the fair value a quantified analysis is required to determine whether an impairment exists. Other intangible assets represent purchased assets that lack physical substance but can be distinguished from goodwill because of contractual or other legal rights and capitalized development, implementation, and license costs of internal-use licensed software. Other intangible assets have finite lives and are reviewed for impairment annually. The amortization of internal-use licensed software begins when a module or a component of a licensed software is ready for its intended use. Other intangible assets are amortized over their estimated useful lives either on a straight-line or sum-of-the-years basis over varying periods that initially do not exceed 15 years.
Other Real Estate Owned	Other Real Estate Owned OREO is comprised of properties acquired in partial or total satisfaction of problem loans. The properties are recorded at fair value less estimated costs of disposal, on the date acquired or on the date that the Company acquires effective control over the property. Gains or losses arising at the time of acquisition of such properties are charged against the allowance for credit losses. During the holding period OREO continues to be measured at lower of cost or fair value less estimated costs of disposal, and any subsequent declines in value are expensed as incurred. Gains and losses realized from the sale of OREO, as well as valuation adjustments and expenses of operation are included in non-interest expense.
Derivative Financial Instruments	Derivative Financial Instruments Derivative Loan Commitments Mortgage loan commitments are derivative loan commitments if the loan that will result from exercise of the commitment will be held for sale upon funding. Derivative loan commitments are recognized at fair value in the Consolidated Statements of Condition in other assets or other liabilities with changes in their fair values recorded as a component of mortgage banking activities in the Consolidated Statements of Income. Mortgage loan commitments are issued to borrowers. Subsequent to commitment date, changes in the fair value of the loan commitment are recognized based on changes in the fair value of the underlying mortgage loan due to interest rate changes, changes in the probability the derivative loan commitment will be exercised, and the passage of time. In estimating fair value, a probability is assigned to a loan commitment based on an expectation that it will be exercised and the loan will be funded. Forward Loan Sale Commitments Loan sales agreements are evaluated to determine whether they meet the definition of a derivative as facts and circumstances may differ significantly. If agreements qualify, to protect against the price risk inherent in derivative loan commitments, the Company utilizes both “mandatory delivery” and “best efforts” forward loan sale commitments to mitigate the risk of potential decreases in the values of loans that would result from the exercise of the derivative loan commitments. Mandatory delivery contracts are accounted for as derivative instruments. Generally, best efforts contracts also meet the definition of derivative instruments after the loan to the borrower has closed. Accordingly, forward loan sale commitments that economically hedge the closed loan inventory are recognized at fair value in the Consolidated Statements of Condition in other assets or other liabilities with changes in their fair values recorded as a component of mortgage banking activities in the Consolidated Statements of Income. The Company estimates the fair value of its forward loan sales commitments using a methodology similar to that used for derivative loan commitments. Interest Rate Swap Agreements The Company enters into interest rate swaps (“swaps”) with commercial loan customers to provide a facility to mitigate the fluctuations in the variable rate on the respective loans. These swaps are matched in exact offsetting terms to swaps that the Company enters into with an outside third party. The swaps are reported at fair value in other assets or other liabilities in the Consolidated Statements of Condition. The Company's swaps qualify as derivatives, but are not designated as hedging instruments, thus any net gain or loss resulting from changes in the fair value is recognized in other non-interest income in the Consolidated Statements of Income. Further discussion of the Company's financial derivatives is set forth in Note 18.
Off-Balance Sheet Credit Risk	Off-Balance Sheet Credit Risk The Company issues financial or standby letters of credit that represent conditional commitments to fund transactions by the Company, typically to guarantee performance of a customer to a third-party related to borrowing arrangements. The credit risk associated with issuing letters of credit is essentially the same as occurs when extending loan facilities to borrowers. The Company monitors the exposure to the letters of credit as part of its credit review process. Extensions of letters of credit, if any, would become part of the loan balance outstanding and would be evaluated in accordance with the Company’s credit policies. Potential exposure to loss for unfunded letters of credit if deemed necessary would be recorded in other liabilities in the Consolidated Statements of Condition. In the ordinary course of business the Company originates and sells whole loans to a variety of investors. Mortgage loans sold are subject to representations and warranties made to the third-party purchasers regarding certain attributes. Subsequent to the sale, if a material underwriting deficiency or documentation defect is determined, the Company may be obligated to repurchase the mortgage loan or reimburse the investor for losses incurred if the deficiency or defect cannot be rectified within a specific period subsequent to discovery. The Company monitors the activity regarding the requirement to repurchase loans and the associated losses incurred. This information is applied to determine an estimated recourse reserve that is recorded in other liabilities in the Consolidated Statements of Condition.
Valuation of Long-Lived Assets	Valuation of Long-Lived Assets The Company reviews long-lived assets, including leases, and certain identifiable intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability is measured by comparing the carrying amount of the asset to future undiscounted net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the estimated fair value of the assets. Assets to be disposed of are reported at the lower of the cost or the fair value, less costs to sell.
Transfers of Financial Assets	Transfers of Financial Assets Transfers of financial assets are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right or from providing more than a trivial benefit to the transferor) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through any agreement to repurchase or redeem them before their maturity or likely cause a holder to return those assets whether through unilateral ability or a price so favorable to the transferee that it is probable that the transferee will require the transferor to repurchase them. A participating interest must be in an entire financial asset and cannot represent an interest in a group of financial assets. Except for compensation paid for services performed, all cash flows from the asset are allocated to the participating interest holders in proportion to their share of ownership. Financial assets obtained or liabilities incurred in a sale are recognized and initially measured at fair value.
Advertising Costs	Advertising Costs Advertising costs are expensed as incurred and included as marketing expense in non-interest expenses in the Consolidated Statements of Income.
Net Income per Common Share	Net Income per Common Share The Company calculates earnings per common share under the two class method, which provides that unvested share-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are participating securities and shall be included in the computation of earnings per share pursuant to the dual class method. The Company has determined that its outstanding non-vested restricted stock awards are participating securities. Under the two class method, basic earnings per common share is computed by dividing net earnings allocated to common shareholders by the weighted average number of common shares outstanding during the applicable period, which excludes outstanding participating securities. Diluted earnings per common share is computed using the weighted average number of common shares determined for the basic earnings per common share computation plus the dilutive effect of incremental stock options and restricted stock.
Income Taxes	Income Taxes Income tax expense is based on the results of operations, adjusted for permanent differences between items of income or expense reported in the financial statements and those reported for tax purposes. Deferred income tax assets and liabilities are determined using the liability method. Under the liability method, deferred income taxes are determined based on the differences between the financial statement carrying amounts and the income tax bases of assets and liabilities and are measured at the enacted tax rates that will be in effect when these differences reverse. The effects of the enactment of the new tax law are accounted for under the existing authoritative guidance.
Adopted Accounting Pronouncements and Pending Accounting Pronouncements applicable to the Company	Adopted Accounting Pronouncements In March 2022, the FASB issued ASU 2022-02, "Financial Instruments - Credit Losses (Topic 326)", which eliminated the accounting guidance on TDRs and amended the guidance on “vintage disclosures” to require disclosure of current period gross charge-offs by year of origination. The ASU also added enhanced disclosures for creditors with respect to loan refinancing and restructurings for borrowers experiencing financial difficulty. The objective of the disclosures was to provide information about the type and magnitude of modifications and the degree of their success in mitigating potential credit losses. The Company fully adopted this update effective January 1, 2023 on a prospective basis. The adoption of this pronouncement did not have a material impact on the Consolidated Financial Statements. In March 2020, the FASB issued ASU 2020-04, “Reference Rate Reform (Topic 848)”. This ASU provided temporary, optional guidance to ease the potential burden in accounting for, or recognizing the effects of, the transition away from the London Interbank Offered Rate ("LIBOR") or other reference rate expected to be discontinued on financial reporting. The standard was elective and provided optional expedients and exceptions for applying GAAP to contracts, hedging relationships, or other transactions that reference LIBOR, or another reference rate expected to be discontinued. The amendments in the update were effective for all entities between March 12, 2020 and December 31, 2022. In January 2021, the FASB issued ASU 2021-01, “Reference Rate Reform (Topic 848): Scope”. This ASU refines the scope of Topic 848 and addresses questions about whether Topic 848 can be applied to derivative instruments that do not reference a rate that is expected to be discontinued, but that use an interest rate for margining, discounting or contract price alignment that is expected to be modified as a result of reference rate reform. ASU 2021-01 is effective upon issuance through December 31, 2024, and can be adopted at any time during this period. The Company has not offered LIBOR for any new contracts since 2021. The Company has identified all known LIBOR exposures, created a plan to address the exposures, and continues to communicate with all stakeholders in order to facilitate the transition to an alternative reference rate. The adoption did not have a material impact on the Company’s Consolidated Financial Statements. Pending Accounting Pronouncements applicable to the Company In November 2023, the FASB issued ASU 2023-07, "Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures", which requires public entities to disclose information about their reportable segments' significant expenses on an interim and annual basis. The ASU is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Entities must adopt this ASU on a retrospective basis. Early adoption is permitted. Currently, the Company does not expect that the adoption of this standard will have a material impact on its Consolidated Financial Statements. 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 allows reporting entities to elect to account for qualifying tax equity investments using the proportional amortization method, regardless of the program giving rise to the related income tax credits. The amendment in this ASU also remove the specialized guidance for low-income-housing tax credit investments that are not accounted for using the proportional amortization method and instead require that those LIHTC investments be accounted for using the guidance in other GAAP. The amendments are effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. The adoption of this pronouncement is not expected to have a material impact on the Consolidated Financial Statements.
