Significant Accounting Policies [Abstract]
Significant Accounting Policies	Note 1 – Significant Accounting Policies Nature of Operations Sandy Spring Bancorp (the “Company” or “Sandy Spring”), a Maryland corporation, is the bank holding company for Sandy Spring Bank (the “Bank”). Independent and community-oriented, Sandy Spring Bank offers a broad range of commercial banking, retail banking, mortgage and trust services throughout central Maryland, Northern Virginia, and the greater Washington, D.C. market. Sandy Spring Bank also offers a comprehensive menu of insurance and wealth management services through its subsidiaries, Sandy Spring Insurance Corporation (“Sandy Spring Insurance”), West Financial Services, Inc. (“West Financial”) and 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”), prevailing practices within the financial services industry for interim financial information and Rule 10-01 of Regulation S-X. Accordingly, the interim financial statements do not include all of the information and notes required for complete financial statements. 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. Operating results for the three months ended March 31, 2020 are not necessarily indicative of the results that may be expected for any future periods or for the year ending December 31, 2020. In the opinion of management, all adjustments (comprising only normal recurring accruals) necessary for a fair presentation of the results of the interim periods have been included. Certain reclassifications have been made to prior period amounts, as necessary, to conform to the current period presentation. The Company has evaluated subsequent events through the date of the issuance of its financial statements. These statements should be read in conjunction with the financial statements and accompanying notes included in the Company’s 2019 Annual Report on Form 10-K as filed with the Securities and Exchange Commission (“SEC”) on February 21, 2020. The Company adopted ASC 326 – Financial Instruments – Credit Losses during the first quarter of 2020. There have been no significant changes to any other of the Company’s accounting policies as disclosed in the 2019 Annual Report on Form 10-K. Principles of Consolidation The unaudited condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary, Sandy Spring Bank, and its subsidiaries, Sandy Spring Insurance Corporation, West Financial Services, Inc. and Rembert Pendleton Jackson. Consolidation has resulted in the elimination of all 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 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. 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 stated 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 Condensed Consolidated Statements of Income. Most of the Company’s revenue is not within the scope of Accounting Standard Update (ASU) No. 2014-09 – Revenue from Contracts with Customers. For revenue within the scope of ASU 2014-09, 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. Wealth Management Income West Financial Services, Inc. and Rembert Pendleton Jackson , subsidiaries of the Bank, 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. Insurance Agency Commissions Sandy Spring Insurance, a subsidiary of the Bank, performs the function of an insurance intermediary by introducing the policyholder and insurer and is compensated by a commission fee for placement of an insurance policy. Sandy Spring Insurance does not provide any captive management services or any claim handling services. Commission fees are set as a percentage of the premium for the insurance policy for which Sandy Spring Insurance is a producer. Sandy Spring Insurance recognizes revenue when the insurance policy has been contractually agreed to by the insurer and policyholder (at transaction date). Service Charges on Deposit Accounts 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. The 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. Obligation for overdraft services is satisfied at the time of the overdraft and revenue is recognized as earned. Allowance for Credit Losses The allowance for credit losses (“allowance” or “ACL”) represents an amount which, in management's judgment, is adequate to absorb 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 operating expense. Determination of the adequacy of the allowance is inherently complex and requires the use of significant and highly subjective estimates. The reasonableness of the allowance is reviewed periodically 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 concentrations of the loan portfolio, expected changes to the economic forecasts, large relationships, early delinquencies, and factors related to credit administrations, 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 – Loans for more details on management’s discussion of 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 or Beacon Scores ranges. 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. At initial adoption of the accounting standard for current expected credit losses (“CECL”), management opted for the application of the reasonable and supportable forecast period of two years under stable economic conditions. However, under the current deteriorated economic conditions, the reasonable and supportable forecast period was adjusted to one year, due to the inherent uncertainty in the future economic outlook. 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 number of business bankruptcies. Contractual loan level cash flows within discounted cash flows methodology are adjusted for the Company’s historical prepayment and curtailment rate experience. The collective quantified component of the allowance is supplemented by a qualitative component to address various risk characteristics of the Company’s loan portfolio including:  trends in early delinquencies;  changes in the risk profile related to large loans in the portfolio;  concentrations of loans to specific industry segments;  expected changes in economic conditions;  changes in the Company’s credit administration and loan portfolio management processes; and  the quality of the Company’s credit risk identification processes. 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 cost 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, 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 cost 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. Management believes it uses relevant information available to make determinations about the allowance and that it has established the existing allowance 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. The adoption of CECL guidance did not result in a significant change to any other credit risk management and monitoring processes, including identification of past due or delinquent borrowers, non-accrual practices, assessment of troubled debt restructurings or charge-off policy. 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 Condensed Consolidated Statements of Condition. 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 lease commencement date, initial direct costs, any lease incentives received and any favorable or unfavorable fair value adjustments on acquired leases. The Company’s lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise such options. 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.

These segments are:  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.  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 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 owner occupied real estate loans - Commercial owned-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 primary source of repayment for this type of loan is the cash flow from the business and is based upon the borrower’s financial health and the ability of the borrower and the business to repay.  Commercial investor real estate loans - Commercial investor real estate loans consist of loans secured by non-owner 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 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.  Consumer loans - This category of loans includes primarily home equity loans and lines, installment loans, personal lines of credit and marine 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.  Residential mortgage loans - The residential mortgage 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 real estate 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 .

The board committee has the discretion when making a grant of stock options to impose restrictions on the shares to be purchased upon the exercise of such options. The Company generally issues authorized but previously unissued shares to satisfy option exercises. The dividend yield is based on estimated future dividend yields. The risk-free rate for periods within the contractual term of the share option is based on the U.S. Treasury yield curve in effect at the time of the grant. Expected volatilities are generally based on historical volatilities. The expected term of share options granted is generally derived from historical experience. Compensation expense is recognized on a straight-line basis over the vesting period of the respective stock option, restricted stock or restricted stock unit grant. The Company recognized compensation expense of $ 0.8 million and $ 0.7 million for the three months ended March 31, 2020 and 2019, respectively, related to the awards of stock options and restricted stock grants. The intrinsic value of stock options exercised in the three months ended March 31, 2020 and 2019 was $ 0.1 million during both periods. The total of unrecognized compensation cost related to stock options was approximately $ 0.1 million as of March 31, 2020. That cost is expected to be recognized over a weighted average period of approximately 1.0year. The total of unrecognized compensation cost related to restricted stock was approximately $ 9.7 million as of March 31, 2020. That cost is expected to be recognized over a weighted average period of approximately 3.3years. The fair value of the options vested during the three months ended March 31, 2020 and 2019, was not significant . The Company granted a total of 181,186 restricted shares, restricted stock units and performance share units in the first quarter of 2020, of which 54,472 units are subject to achievement of certain performance conditions measured over a three year performance period and 126,714 shares or units subject to a three- or five-year vesting schedule.

Pension Profit Sharing, and Other Employee Benefit Plans	Note 11 – Pension, Profit Sharing, and Other Employee Benefit Plans Defined Benefit Pension Plan The Company has a qualified, noncontributory, defined benefit pension plan (the “Plan”). Benefits after January 1, 2005, are based on the benefit earned as of December 31, 2004, plus benefits earned in future years of service based on the employee’s compensation during each such year. All benefit accruals for employees were frozen as of December 31, 2007 based on past service and thus salary increases and additional years of service after such date no longer affect the defined benefit provided by the Plan, although additional vesting may continue to occur. The Company's funding policy is to contribute amounts to the Plan sufficient to meet the minimum funding requirements of the Employee Retirement Income Security Act of 1974 (“ERISA”), as amended. In addition, the Company contributes additional amounts as it deems appropriate based on benefits attributed to service prior to the date of the Plan freeze. The Plan invests primarily in a diversified portfolio of managed fixed income and equity funds.

Financial Instruments With Off- Balance Sheet Risk and Derivatives [Abstract]
Financial Instruments With Off-Balance Sheet Risk and Derivatives	Note 15 – Financial Instruments with Off-balance Sheet Risk and Derivatives The Company has entered into interest rate swaps (“swaps”) to facilitate customer transactions and meet their financing needs. These swaps qualify as derivatives, but are not designated as hedging instruments. Interest rate swap contracts involve the risk of dealing with counterparties and their ability to meet contractual terms. When the fair value of a derivative instrument contract is positive, this generally indicates that the counterparty or customer owes the Company and results in credit risk to the Company. When the fair value of a derivative instrument contract is negative, the Company owes the customer or counterparty and, therefore, has no credit risk. The notional value of commercial loan swaps outstanding was $ 204.2 million with a fair value of $ 9.6 million as of March 31, 2020 compared to $ 204.7 million with a fair value of $ 2.5 million as of December 31, 2019. The swap positions are offset to minimize the potential impact on the Company’s financial statements. Fair values of the swaps are carried as both gross assets and gross liabilities in the Condensed Consolidated Statements of Condition. The associated net gains and losses on the swaps are recorded in other non-interest income.

FAIR VALUE

FAIR VALUE	3 Months Ended

Fair Value [Abstract]
Fair Value	Note 17 – Fair Value Generally accepted accounting principles provide 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 held for sale allows the recognition of gains on the 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, changes to interest rates could result in higher or lower measurements of the fair values. Assets and Liabilities Mortgage loans held for sale Mortgage loans held for sale are valued based on quotations from the secondary market for similar instruments and are classified as Level 2 of the fair value hierarchy. Investments available-for-sale U.S. government agencies, 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 conditions databases coupled with extensive quality control programs. Multiple quality control evaluation processes review available market, credit and deal level information to support the evaluation of the security. If there is a lack of objectively verifiable information available to support the valuation, the evaluation of the security is discontinued. 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 generally classified within Level 2 of the fair value hierarchy. State and municipal securities Proprietary valuation matrices are used for valuing all tax-exempt municipals that can incorporate changes in the municipal market as they occur. Market evaluation models include the ability to value bank qualified municipals and general market municipals that can be broken down further according to insurer, credit support, state of issuance and rating to incorporate additional spreads and municipal curves. Taxable municipals are valued using a third party model that incorporates a methodology that captures the trading nuances associated with these bonds. Such instruments are generally classified within Level 2 of the fair value hierarchy. Interest rate swap agreements Interest rate swap agreements are measured by alternative pricing sources with reasonable levels of price transparency in markets that are not active. 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 markets do however have comparable, observable inputs in which an alternative pricing source values these assets in order to arrive at a fair market value. These characteristics classify interest rate swap agreements as Level 2. Assets Measured at Fair Value on a Recurring Basis The following tables set forth the Company’s financial assets and liabilities at the dates 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: March 31, 2020 Quoted Prices in Significant Active Markets for Significant Other Unobservable Identical Assets Observable Inputs Inputs (In thousands) (Level 1) (Level 2) (Level 3) Total Assets Residential mortgage loans held for sale $ - $ 67,114 $ - $ 67,114 Investments available-for-sale: U.S. government agencies - 180,344 - 180,344 State and municipal - 276,449 - 276,449 Mortgage-backed and asset-backed - 718,482 - 718,482 Corporate debt - - 12,332 12,332 Trust preferred - - - - Marketable equity securities - 568 - 568 Interest rate swap agreements - 9,571 - 9,571 Liabilities Interest rate swap agreements $ - $ ( 9,571) $ - $ ( 9,571) December 31, 2019 Quoted Prices in Significant Active Markets for Significant Other Unobservable Identical Assets Observable Inputs Inputs (In thousands) (Level 1) (Level 2) (Level 3) Total Assets Residential mortgage loans held for sale $ - $ 53,701 $ - $ 53,701 Investments available-for-sale: U.S. government agencies - 258,495 - 258,495 State and municipal - 233,649 - 233,649 Mortgage-backed and asset-backed - 570,759 - 570,759 Corporate debt - - 9,552 9,552 Trust preferred - - 310 310 Marketable equity securities - 568 - 568 Interest rate swap agreements - 2,507 - 2,507 Liabilities Interest rate swap agreements $ - $ ( 2,507) $ - $ ( 2,507) The following table provides a change in the fair value of assets measured in the Condensed Consolidated Statements of Condition at fair value with significant unobservable inputs (Level 3) on a recurring basis for the period indicated: Significant Unobservable Inputs (In thousands) (Level 3) Investments available-for-sale: Balance at January 1, 2020 $ 9,862 Additions of Level 3 assets 3,050 Sales of Level 3 assets ( 310) Total unrealized loss included in other comprehensive income ( 270) Balance at March 31, 2020 $ 12,332 Assets Measured at Fair Value on a Nonrecurring Basis The following table sets forth the Company’s financial assets subject to fair value adjustments on a nonrecurring basis at the date indicated that are valued at the lower of cost or market.

Loans totaling $ 24.8 million were written down to fair value of $ 19.3 million at December 31, 2019 as a result of individual credit loss allowances of $5.5 million associated with the collateral dependent 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. Other real estate owned (“OREO”) is adjusted to fair value upon acquisition of the real estate collateral. Subsequently, OREO is carried at the lower of carrying value or fair value. The estimated fair value for OREO included in Level 3 is determined by independent market based appraisals and other available market information, less cost to sell, 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. The carrying amounts and fair values of the Company’s financial instruments at the dates indicated are presented in the following table: Fair Value Measurements March 31, 2020 Quoted Prices in Estimated Active Markets for Significant Other Significant Carrying Fair Identical Assets Observable Inputs Unobservable Inputs (In thousands) Amount Value (Level 1) (Level 2) (Level 3) Financial Assets Other equity securities $ 62,953 $ 62,953 $ - $ 62,953 $ - Loans, net of allowance 6,637,192 6,721,435 - - 6,721,435 Other assets (1) 113,817 113,817 - 113,817 - Financial Liabilities Time deposits $ 1,646,611 $ 1,663,576 $ - $ 1,663,576 $ - Securities sold under retail repurchase agreements and Federal funds purchased 125,305 125,305 - 125,305 - Advances from FHLB 754,061 770,511 - 770,511 - Subordinated debentures 199,046 183,857 - - 183,857 (1) Includes bank owned life insurance products.

Segment Reporting	N ote 18 - Segment Reporting Currently, the Company conducts business in three operating segments - Community Banking, Insurance and Investment Management. Each of the operating segments is a strategic business unit that offers different products and services. The Insurance and Investment Management segments were businesses that were acquired in separate transactions where management of the acquired business was retained. The accounting policies of the segments are the same as those of the Company. However, the segment data reflects inter-segment transactions and balances. The Community Banking segment is conducted through Sandy Spring Bank and involves delivering a broad range of financial products and services, including various loan and deposit products, to both individuals and businesses. Parent company income is included in the Community Banking segment, as the majority of parent company functions is related to this segment. Major revenue sources include net interest income, gains on sales of mortgage loans, trust income fees and service charges on deposit accounts. Expenses include personnel, occupancy, marketing, equipment and other expenses. Non-cash charges associated with amortization of intangibles were $ 0.4 million for both the three months ended March 31, 2020 and 2019 , respectively. The Insurance segment is conducted through Sandy Spring Insurance Corporation, a subsidiary of the Bank. Sandy Spring Insurance Corporation operates Sandy Spring Insurance, a general insurance agency located in Annapolis, Maryland, and Neff and Associates, located in Ocean City, Maryland. Major sources of revenue are insurance commissions from commercial lines, personal lines, and medical liability lines. Expenses include personnel and support charges. Non-cash charges associated with amortization of intangibles were not significant for the three months ended March 31, 2020 and 2019, respectively. The Investment Management segment is conducted through West Financial Services, Inc. and Rembert Pendleton Jackson, subsidiaries of the Bank. These asset management and financial planning firms, located in McLean, Virginia and Falls Church, Virginia, provide comprehensive investment management and financial planning to individuals, families, small businesses and associations, including cash flow analysis, investment review, tax planning, retirement planning, insurance analysis and estate planning. West Financial and RPJ had approximately $ 2.6 billion in assets under management as of March 31, 2020. Major revenue sources include non-interest income earned on the above services. Expenses include personnel and support charges. Non-cash charges associated with amortization of intangibles were $ 0.2 million for the three months ended March 31, 2020 and were not significant for the same period in the prior year.

In the opinion of management, all adjustments (comprising only normal recurring accruals) necessary for a fair presentation of the results of the interim periods have been included. Certain reclassifications have been made to prior period amounts, as necessary, to conform to the current period presentation. The Company has evaluated subsequent events through the date of the issuance of its financial statements. These statements should be read in conjunction with the financial statements and accompanying notes included in the Company’s 2019 Annual Report on Form 10-K as filed with the Securities and Exchange Commission (“SEC”) on February 21, 2020. The Company adopted ASC 326 – Financial Instruments – Credit Losses during the first quarter of 2020. There have been no significant changes to any other of the Company’s accounting policies as disclosed in the 2019 Annual Report on Form 10-K.
Principles of Consolidation	Principles of Consolidation The unaudited condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary, Sandy Spring Bank, and its subsidiaries, Sandy Spring Insurance Corporation, West Financial Services, Inc. and Rembert Pendleton Jackson. Consolidation has resulted in the elimination of all 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 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.
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 stated 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 Condensed Consolidated Statements of Income. Most of the Company’s revenue is not within the scope of Accounting Standard Update (ASU) No. 2014-09 – Revenue from Contracts with Customers. For revenue within the scope of ASU 2014-09, 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. Wealth Management Income West Financial Services, Inc. and Rembert Pendleton Jackson , subsidiaries of the Bank, 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. Insurance Agency Commissions Sandy Spring Insurance, a subsidiary of the Bank, performs the function of an insurance intermediary by introducing the policyholder and insurer and is compensated by a commission fee for placement of an insurance policy. Sandy Spring Insurance does not provide any captive management services or any claim handling services. Commission fees are set as a percentage of the premium for the insurance policy for which Sandy Spring Insurance is a producer. Sandy Spring Insurance recognizes revenue when the insurance policy has been contractually agreed to by the insurer and policyholder (at transaction date). Service Charges on Deposit Accounts 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. The 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. Obligation for overdraft services is satisfied at the time of the overdraft and revenue is recognized as earned.
Allowance for Credit Losses	Allowance for Credit Losses The allowance for credit losses (“allowance” or “ACL”) represents an amount which, in management's judgment, is adequate to absorb 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 operating expense. Determination of the adequacy of the allowance is inherently complex and requires the use of significant and highly subjective estimates. The reasonableness of the allowance is reviewed periodically 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 concentrations of the loan portfolio, expected changes to the economic forecasts, large relationships, early delinquencies, and factors related to credit administrations, 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 – Loans for more details on management’s discussion of 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 or Beacon Scores ranges. 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. At initial adoption of the accounting standard for current expected credit losses (“CECL”), management opted for the application of the reasonable and supportable forecast period of two years under stable economic conditions. However, under the current deteriorated economic conditions, the reasonable and supportable forecast period was adjusted to one year, due to the inherent uncertainty in the future economic outlook. 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 number of business bankruptcies. Contractual loan level cash flows within discounted cash flows methodology are adjusted for the Company’s historical prepayment and curtailment rate experience. The collective quantified component of the allowance is supplemented by a qualitative component to address various risk characteristics of the Company’s loan portfolio including:  trends in early delinquencies;  changes in the risk profile related to large loans in the portfolio;  concentrations of loans to specific industry segments;  expected changes in economic conditions;  changes in the Company’s credit administration and loan portfolio management processes; and  the quality of the Company’s credit risk identification processes. 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 cost 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, 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 cost 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. Management believes it uses relevant information available to make determinations about the allowance and that it has established the existing allowance 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. The adoption of CECL guidance did not result in a significant change to any other credit risk management and monitoring processes, including identification of past due or delinquent borrowers, non-accrual practices, assessment of troubled debt restructurings or charge-off policy.
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 Condensed Consolidated Statements of Condition. 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 lease commencement date, initial direct costs, any lease incentives received and any favorable or unfavorable fair value adjustments on acquired leases. The Company’s lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise such options. 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.
