Significant Accounting Policies [Abstract]
Significant Accounting Policies	Note 1 – Significant Accounting Policies Nature of Operations Sandy Spring Bancorp (the “Company”), a Maryland corporation, is the bank holding company for Sandy Spring Bank (the “Bank”), which conducts a full-service commercial banking, mortgage banking and trust business. Services to individuals and businesses include accepting deposits, extending real estate, consumer and commercial loans and lines of cred it, equipment leasing, general insurance, personal trust, and investment and wealth management servi ces. The Company operates in central Maryland, Northern Virginia, and the greater Washington D.C. market. The Company offers investment and wealth manageme nt services through the Bank’s subsidiary, West Financial Services. Insurance products are available to clients through Sandy Spring Insurance, and Neff & Associates, which are agencies of Sandy Spring Insurance Corporation. Basis of Presentation The ac counting 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 reclassifications have been made to prior period amounts to conform to the current period pre sentation. 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, Sa ndy Spring Bank and its subsidiaries, Sandy Spring Insurance Corporation and West Financial Services, Inc. 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, and affect the reported am ounts 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 loan losses and the related allowance, determination of impa ired loans and the related measurement of impairment, potential impairment of goodwill or other intangible assets, valuation of investment securities and the determination of whether impaired securities are other-than-temporarily impaired, valuation of oth er 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 pe nsion 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 balance sheets. 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 inc lude cash and due from banks, federal funds sold and interest-bearing deposits with banks (items with an original maturity of three months or less). Residential Mortgage Loans Held for Sale The Company engages in sales of residential mortgage loans origin ated 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), as permitted by current accounting standards. 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 Compa ny'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 fo r impairment on a periodic basis. Investments Held-to-Maturity Investments held-to-maturity represents securities which the Company has the ability and positive intent to hold until maturity. These securities are recorded at cost at the time of acq uisition. The carrying values of investments held-to-maturity are adjusted for premium amortization and discount accretion to the maturity date on the effective interest method. Related interest and dividends are included in interest income. Declines in t he fair value of individual held-to-maturity investments below their cost that are other-than-temporary result in write-downs of the individual securities to their fair value. Factors that may affect the determination of whether other-than-temporary impai rment (“OTTI”) has occurred include a downgrading of the security below investment grade by the rating agency or due to potential default, a significant deterioration in the financial condition of the issuer, or that management would not have the ability t o hold a security for a period of time sufficient to allow for any anticipated recovery in fair value. During 2016, all investments held-to-maturity were transferred to investments available-for-sale. Accordingly, acquisitions of investments in the futur e will not be classified as held-to-maturity. Investments Available-for-Sale Marketable equity securities and 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 unrealiz ed 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 carrying values 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 dividends are included in interest income . Declines in the fair value of individual available-for-sale securities below their cost that are other-than-temporary (“OTTI”) result in write-downs of the individual securities to their fair value. Factors affecting the determination of whether other- than-temporary 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, or a change in management’s intent and ability to hold a security for a period of time sufficient to allow for any anticipated recovery in fair value. Other Equity Securities Other equity securities include Federal Reserve stock, Federal Home Loan Bank of Atlanta stock and other equities that are considered restricted as to marketability and recorded at cost. These securities are carried at cost and evaluated for impairment each reporting period. Lo an Financing Receivables The Company’s financing receivables consist primarily of loans that are stated at their principal balance outstanding net of any unearned income and deferred fees and costs. Interest income on loans is accrued at the contractual ra te based on the principal 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 in terest payment or portion thereof, the amount reported as delinquent is the outstanding principal balance of the loan. Loans , except for consumer 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 a mounts 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 w hen they are four months past due. Loans designated as non-accrual have all previously accrued but unpaid interest reversed. Payments received on non-accrual loans when doubt about the ultimate collectability of the principal no longer exists may have th eir interest payments recorded as interest income on a cash basis or using the cost-recovery method with all payments applied to reduce the outstanding principal until the loan returns to accrual status. Loans may be returned to accrual status when all pr incipal and interest amounts contractually due are brought current and future payments are reasonably assured. Large groups of smaller balance homogeneous loans are not individually evaluated for impairment and include lease financing receivables, residen tial permanent and construction mortgages and consumer installment loans. All other loans are considered non-homogeneous and are evaluated for impairment if they are placed in non-accrual status. Loans are determined to be impaired when, based on availab le information, it is probable that the Company may not collect all principal and interest payments according to contractual terms. Factors considered in determining whether a loan is impaired include: the financial condition of the borrower; reliability a nd sources of the cash flows; absorption or vacancy rates; and deterioration of related collateral. The impairment of a loan is measured based on the present value of expected future cash flows discounted at the loan's original effective interest rate, or as permitted, the impairment may be measured based on a loan’s observable market price or the fair value of the collateral less cost to sell. The majority of the Company’s impaired loans are considered to be collateral dependent and impairment is meas ured by determining the fair value of the collateral using third party appraisals 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. The Company may receive updated appraisals which contradict the preliminary determination of fai r value used to establish a specific allowance on a loan. In these instances the specific allowance is adjusted to reflect the Company’s evaluation of the 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 charge d-off loans are accounted for under the cost-recovery method. Under this method, all payments are applied on a cash basis to reduce the entire outstanding principal, then to recognize a recovery of all previously charged-off amounts before interest income may be recognized. Based on the impairment evaluation, if the Company determines an estimable loss exists, a specific allowance will be established for that loan. Once a loss has been confirmed, the loan is charged-down to its estimated net realizable v alue. Interest income on impaired loans is recognized using the same method as non-accrual loans, with the exception of loans that are considered troubled debt restructurings. Loans considered to be troubled debt restructurings (“TDRs”) are loans that h ave their terms restructured (e.g., interest rates, loan maturity date, payment and amortization period, etc.) in circumstances that provide payment relief to a borrower experiencing financial difficulty. All restructured loans are considered impaired loan s and may either be in accruing status or non-accruing status. Non-accruing restructured loans may return to accruing status provided doubt has been removed concerning the collectability of principal and interest as evidenced by a sufficient period of pay ment performance in accordance with the restructured terms. Loans may be removed from the restructured category if the borrower is no longer experiencing financial difficulty, a re-underwriting event took place and the revised loan terms of the subsequent restructuring agreement are considered to be consistent with terms that can be obtained in the credit market for loans with comparable risk. Management uses relevant information available to make the determination on whether loans are impaired in accor dance with GAAP. However, the determination of whether loans are impaired and the measurement of the impairment requires significant judgment, and estimates of losses inherent in the loan portfolio can vary significantly from the amounts actually observed. Allowance for Loan Losses The allowance for loan losses (“allowance” or “ALL ”) represents an amount which, in management's judgment, is adequate to absorb the probable estimate of losses that may be sustained on outstanding loans at the balance sheet dat e based on the evaluation of the size and current risk characteristics of the loan portfolio. The allowance is reduced by charge-offs, net of recoveries of previous losses, and is increased or decreased by a provis ion or credit for loan losses, which is r ecorded as a current period operating expense. The allowance is based on the basic principle that a loss be accrued when it is probable that the loss has occurred and the amount of the loss can be reasonably estimated. Determination of the adequacy of t he allowance is inherently complex and requires the use of significant and highly subjective estimates. The reasonableness o f the allowance is reviewed periodically by the Risk Committee of the board of directors and formally approved quarterly by that sa me committee of the board. The Company’s methodology for estimating the allowance includes a general component reflecting historical losses, as adjusted, by loan portfolio segment, and a specific component for impaired loans. There were no changes in the Company’s allowance policies or methodology from the prior year. The general component is based upon historical loss experience by each portfolio segment measured, over the prior eight quarters weighted equally . The historical loss experience is suppleme nted to address various risk characteristics of the Company’s loan portfolio including: trends in delinquencies and other non-performing loans; changes in the risk profile related to large loans in the portfolio; changes in the categories of loans comprising the loan portfolio; concentrations of loans to specific industry segments; changes in economic conditions on both a local and national level; changes in the Company’s credit administration and loan portfolio management processes; and the quality of the Company’s credit risk identification processes. The general component is calculated in two parts based on an internal risk classification of loans within each portfolio segment. Reserves on loans considered to be “classified” under regulatory guidance are calculated separately from loans considered to be “pass” rated under the same guidance. This segregation allows the Company to monitor the allowance component applicable to higher risk loans separate from t he remainder of the portfolio in order to better manage risk and reasonably determine the sufficiency of reserves. Integral to the assessment of the allowance process is an evaluation that is performed to determine whether a specific allowance on an impai red credit is warranted. For the particular loan that may have potential impairment, an appraisal will be ordered depending on the time elapsed since the prior appraisal, the loan balance and/or the result of the internal evaluation. The Company typicall y relies on current (12 months old or less) third party appraisals of the collateral to assist in measuring impairment. In the cases in which the Company does not rely on a third party appraisal, an internal evaluation is prepared by an approved credit off icer. A current appraisal on large loans is usually obtained if the appraisal on file is more than 12 months old and there has been a material change in market conditions, zoning, physical use or the adequacy of the collateral based on an internal evaluat ion. The Company’s policy is to strictly adhere to regulatory appraisal standards. If an appraisal is ordered, no more than a 30 day turnaround is requested from the appraiser, who is selected by Credit Administration from an approved appraiser list. Afte r receipt of the updated appraisal, the assigned credit officer will recommend to the Chief Credit Officer whether a specific allowance or a charge-off should be taken. When losses are confirmed, a charge-off is taken that is at least in the amount of the collateral deficiency as determined by the independent third party appraisal. Any further collateral deterioration results in either further specific reserves being established or additional charge-offs. The Chief Credit Officer has the authority to appr ove a specific allowance or charge-off between monthly credit committee meetings to ensure that there are no significant time lapses during this process. The portion of the allowance representing specific allowances is established on individually impaire d loans. As a practical expedient, for collateral dependent loans, the Company measures impairment based on the net realizable value of the underlying collateral. For loans on which the Company has not elected to use a practical expedient to measure impair ment, the Company will measure impairment based on the present value of expected future cash flows discounted at the loan’s effective interest rate. In determining the cash flows to be included in the discount calculation the Company considers the followi ng factors that combine to estimate the probability and severity of potential losses: the borrower’s overall financial condition; resources and payment record; demonstrated or documented support available from financial guarantors; and the adequacy of col lateral value and the ultimate realization of that value at liquidation. 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. Howe ver, the determination of the allowance requires significant judgment, and estimates of proba ble losses in the loan portfolio can vary significantly from the amounts actually observed. While management uses available information to recognize inherent losse s, future additions to the allowance may be necessary based on changes in th e loans comprising the portfolio and changes in the financial condition of borrowers, such as may result from changes in economic conditions. In addition, various regulatory age ncies, as an integral part of their examination process, and independent consultants engaged by the Company, period ically review the loan portfolio and the allowance. Such review may result in additional provisions based on management’s judgments of infor mation available at the time of each examination. 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 o ver 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. Goodwill and Other I ntangible 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 circums tances 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 u nits 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. The Company tests for impairment of goodwill as of October 1 of each year, and again at any quarter-end if any triggering events occur during a quarter that may affect goodwill. Examples of such events include, but are not limited to, adverse action by a regulator or a los s of key personnel. Determining the fair value of a reporting unit requires the Company to use a degree of subjectivity. Current accounting guidance provides the option to first assess qualitative factors to determine whether the existence of events o r 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 f actors, if it is determined that the fair value of a reporting unit is not less than the carrying value, then performing the two-step impairment process, previously required, is unnecessary. However, if it is determined that the carrying value exceeds the fair value the first step, described above, of the two-step process must be performed. At December 31, 2017 and 2016 there was no evidence of impairment of goodwill or intangibles in any of the Company’s reporting units. Other intangible assets re pr esent purchased assets that lack physical substance but can be distinguished from goodwill because of contractual or other legal rights or because the asset is capable of being sold or exchanged either on its own or in combination with a related contract, asset, or liability. Other intangible assets have finite lives and are reviewed for impairment annually. These assets are amortized over t heir estimated useful lives either on a straight-line or sum-of-the-years basis over varying periods that initially d id not exceed 15 years. Other Real Estate Owned (“OREO”) 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 loan 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 on 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. Mo rtgage l oan 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 S ale 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 comm itments, 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 de livery 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 hedg e the closed loan inventory are recognized at fair value on 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 statement s 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 loa n 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 fa ir value in other assets or other liabilities. 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. Furthe r discussion of the Company's financial derivatives is set forth in Note 18 to the Consolidated Financial Statements. 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 facilit ies 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 Co mpany’s credit policies. Potential exposure to loss for unfunded letters of credit if deemed necessary would be recorded in other liabilities. In the ordinary course of business the Company originates and sells whole loans to a variety of investors. Mor tgage 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 obl igated 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 repurchas e loans and the associated losses incurred. This information is applied to determine an estimated recourse reserve that is recorded in other liabilities. Valuation of Long-Lived Assets The Company reviews long-lived assets and certain identifiable intang ible 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 a comparing the carrying amount of the asset to future undiscounted net cash flows e xpected 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 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 whe ther 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 inc urred in a sale are recognized and initially measured at fair value. Insurance Commissions and Fees Commission revenue is recognized over the term of the coverage period . The Company also receives contingent commissions from insurance companies as addi tional incentive for achieving specified premium volume goals and/or the loss experience of the insurance placed by the Company. Contingent commissions from insurance companies are recognized when determinable, which is generally when such commissions are received. Advertising Costs Advertising costs are expensed as incurred and included in non-interest expenses. Net Income per Common Share The Company calculates earnings per common share under the dual class method , which provides that unvested share-ba sed payment awards that contain nonforfeitable 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 h as determined that its outstanding non-vested restricted stock awards are participating securities. Under the dual class method, basic earnings per common share is computed by dividing net earnings allocated to common stock by the weighted-average number of commo

These declines are considered temporary in nature and will decline over time and recover as these securities approach maturity. The mortgage-backed portfolio at December 31, 2017 is composed entirely of ei ther the most senior tranches of GNMA , FNMA or FHLMC collaterali zed mortgage obligations ($10 2 . 6 million), or GNMA, FNMA or FHLMC mo rtgage-backed securities ($197.5 million). The Company does not intend to sell these securities and has sufficient liquidit y to hold these securities for an adequate period of time, which may be maturity, to allow for any anticipated recovery in fair value. At December 31, 2017 the trust preferred portfolio consisted of one pooled trust preferred security. The pooled trust preferred security, which is backed by debt issued by banks and thrifts, totals $0 . 9 million with a fair value of $1.0 million. The fai r value of this security was determined by management through the use of a third party valuation specialist due to the limited trading activity for this security. As a result of this evaluation, it was determined that the pooled trust preferred security had not incurred any credit-related other-than-temporary imp airment (“OTTI”) for the year ended December 31, 2017 . The unrealized gain on this security that is recognized in other comprehensive income (“OCI”) and is not expected to be sold and which the C ompany has the ability to hold until maturity, was $0.1 million at December 31, 2017.

Receivables [Abstract]
LOANS AND LEASES	Note 4 – Loans The lending business of the Company is based on understanding, measuring and controlling the credit risk inherent in the loan portfoli o. 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 collat eral type. Outstanding loan balances at December 31, 2017 and 2016 are net of unearned income including net deferred loan costs of $1.8 million and $1.4 million, respectively . The loan portfolio segment balances at December 31 are presented in the following table: (In thousands) 2017 2016 Residential real estate: Residential mortgage $ 921,435 $ 841,692 Residential construction 176,687 150,229 Commercial real estate: Commercial owner occupied real estate 857,196 775,552 Commercial investor real estate 1,112,710 928,113 Commercial AD&C 292,443 308,279 Commercial Business 497,948 467,286 Consumer 455,829 456,657 Total loans $ 4,314,248 $ 3,927,808 Portfolio Segments The Company currently manages its credit products and the respective exposure to credit losses (credit risk) by the following specific portfolio segments (classes) which are levels at which the Company develops and documents its systematic methodology to determine the allowance for loan losses attributable to each respective portfolio segment. These segments are: Commercial business loans – Commercial loans are made to provide funds for equipment and general corporate needs. Re payment of a loan primarily uses 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 r eceivables 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 dev elopment 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 a nd 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 a nd 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 consis ts 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 automobile s, boats and recreational vehicles. Residential mortgage loans – The residential real estate category contains permanent mortgage loans principally to consumers secured by residential real estate. Residential real estate loans are evaluated for the adequac y 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 re al 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.

Credit Quality Assessment [Abstract]
CREDIT QUALITY ASSESSMENT	Note 5 – CREDIT QUALITY ASSESSMENT Allowance for Loan Losses Credit risk can vary significantly as losses, as a percentage of outstanding loans, can vary widely during economic cycles and are sensitive to changing economic conditions. The amount of loss in any particular type of loan can vary depending on the purpose of the loan and the underlying collateral securing the loan. Collateral securing commercial loans can range from accounts receivable to equipment to improved or unimprov ed real estate depending on the purpose of the loan. Home mortgage and home equity loans and lines are typically secured by first or second liens on residential real estate. Consumer loans may be secured by personal property, such as auto loans or they m ay be unsecured loan products. Management has an internal credit process in place to maintain credit standards. This process along with an in-house loan administration, accompanied by oversight and review procedures, combines to control and manage credit risk. The primary purpose of loan underwriting is the evaluation of specific lending risks that involves the analysis of the borrower’s ability to service the debt as well as the assessment of the value of the underlying collateral. Oversight and review procedures include the monitoring of the portfolio credit quality, early identification of potential problem credits and the management of the problem credits. As part of the oversight and review process, the Company maint ains an allowance for loan losses (the “allowance”) to absorb estimated and proba ble losses in the loan portfolio . The allowance is based on consistent, periodic review and evaluation of the loan portfolio, along with ongoing, monthly assessments of the pro bable losses and problem credits in each portfolio. While portions of the allowance are attributed to specific portfolio segments, the entire allowance is available to absorb credit losses inherent in the total loan portfolio. Summary information on the allowance for loan loss activity for the years ended December 31 is provided in the following table: (In thousands) 2017 2016 2015 Balance at beginning of year $ 44,067 $ 40,895 $ 37,802 Provision for loan losses 2,977 5,546 5,371 Loan charge-offs (2,566) (3,134) (3,795) Loan recoveries 779 760 1,517 Net charge-offs (1,787) (2,374) (2,278) Balance at period end $ 45,257 $ 44,067 $ 40,895 The following tables provide information on the activity in the allowance for loan losses by the respective loan portfolio segment for the years ended December 31: 2017 Commercial Real Estate Residential Real Estate Commercial Commercial Commercial Commercial Owner Residential Residential (Dollars in thousands) Business AD&C Investor R/E Occupied R/E Consumer Mortgage Construction Total Balance at beginning of year $ 7,539 $ 4,652 $ 12,939 $ 7,885 $ 2,828 $ 7,261 $ 963 $ 44,067 Provision (credit) 2,616 (1,254) 1,930 (459) (57) (56) 257 2,977 Charge-offs (1,538) - - (248) (693) (87) - (2,566) Recoveries 94 103 101 - 305 150 26 779 Net (charge-offs)/ recoveries (1,444) 103 101 (248) (388) 63 26 (1,787) Balance at end of period $ 8,711 $ 3,501 $ 14,970 $ 7,178 $ 2,383 $ 7,268 $ 1,246 $ 45,257 Total loans $ 497,948 $ 292,443 $ 1,112,710 $ 857,196 $ 455,829 $ 921,435 $ 176,687 $ 4,314,248 Allowance for loans to total loans ratio 1.75% 1.20% 1.35% 0.84% 0.52% 0.79% 0.71% 1.05% Balance of loans specifically evaluated for impairment $ 8,105 $ 136 $ 5,575 $ 4,078 na. $ 2,915 $ - $ 20,809 Allowance for loans specifically evaluated for impairment $ 3,220 $ - $ 663 $ 131 na. $ - $ - $ 4,014 Specific allowance to specific loans ratio 39.73% na. 11.89% 3.21% na. na. na. 19.29% Balance of loans collectively evaluated $ 489,843 $ 292,307 $ 1,107,135 $ 853,118 $ 455,829 $ 918,520 $ 176,687 $ 4,293,439 Allowance for loans collectively evaluated $ 5,491 $ 3,501 $ 14,307 $ 7,047 $ 2,383 $ 7,268 $ 1,246 $ 41,243 Collective allowance to collective loans ratio 1.12% 1.20% 1.29% 0.83% 0.52% 0.79% 0.71% 0.96% 2016 Commercial Real Estate Residential Real Estate Commercial Commercial Commercial Commercial Owner Residential Residential (Dollars in thousands) Business AD&C Investor R/E Occupied R/E Consumer Mortgage Construction Total Balance at beginning of year $ 6,529 $ 4,691 $ 10,440 $ 7,984 $ 3,456 $ 6,901 $ 894 $ 40,895 Provision (credit) 1,563 (31) 2,563 (104) 112 1,406 37 5,546 Charge-offs (597) (48) (197) - (888) (1,404) - (3,134) Recoveries 44 40 133 5 148 358 32 760 Net (charge-offs)/ recoveries (553) (8) (64) 5 (740) (1,046) 32 (2,374) Balance at end of period $ 7,539 $ 4,652 $ 12,939 $ 7,885 $ 2,828 $ 7,261 $ 963 $ 44,067 Total loans $ 467,286 $ 308,279 $ 928,113 $ 775,552 $ 456,657 $ 841,692 $ 150,229 $ 3,927,808 Allowance for loans total loans ratio 1.61% 1.51% 1.39% 1.02% 0.62% 0.86% 0.64% 1.12% Balance of loans specifically evaluated for impairment $ 7,018 $ 137 $ 8,107 $ 5,567 na. $ 3,263 $ - $ 24,092 Allowance for loans specifically evaluated for impairment $ 2,604 $ - $ 1,736 $ 485 na. $ - $ - $ 4,825 Specific allowance to specific loans ratio 37.10% na. 21.41% 8.71% na. na. na. 20.03% Balance of loans collectively evaluated $ 460,268 $ 308,142 $ 920,006 $ 769,985 $ 456,657 $ 838,429 $ 150,229 $ 3,903,716 Allowance for loans collectively evaluated $ 4,935 $ 4,652 $ 11,203 $ 7,400 $ 2,828 $ 7,261 $ 963 $ 39,242 Collective allowance to collective loans ratio 1.07% 1.51% 1.22% 0.96% 0.62% 0.87% 0.64% 1.01% The Company’s methodology for evaluating whether a loan is impaired begins with risk-rating credits on an individual basis and includes consideration of the borrower’s overall financial condition, payment record and available cash resources that may include the collateral value and, in a select few cases, verifiable support from financial guarantors. In measuring impairment, the Company looks primarily to the discounted cash flows of the project itself or to the value of the collateral as the primary sources of repayment of the loan. Collateral values or estimates of discounted cash flows (inclusive of any potential cash flow from guarantees) are evaluated to estimate the probability and severity of potential losses. The actual occurrence and severi ty of losses involving impaired credits can differ substantially from estimates. The Company may consider the existence of guarantees and the financial strength and wherewithal of the guarantors involved in any loan relationship. Guarantees may be consi dered as a source of repayment based on the guarantor’s financial condition and respective payment capacity. Accordingly, absent a verifiable payment capacity, a guarantee alone would not be sufficient to avoid classifying the loan as impaired. Manageme nt has established a credit process that dictates that procedures be performed to monitor impaired loans between the receipt of an original appraisal and the updated appraisal. These procedures include the following: An internal evaluation is updated qua rterly to include borrower financial statements and/or cash flow projections. The borrower may be contacted for a meeting to discuss an updated or revised action plan which may include a request for additional collateral. Re-verification of the documentati on supporting the Company’s position with respect to the collateral securing the loan. At the monthly credit committee meeting the loan may be downgraded. Upon receipt of the updated appraisal or based on an updated internal financial evaluation, the loan balance is compared to the appraisal and a specific allowance is determined for the particular loan, typically for the amount of the difference between the appraisal and the loan balance. The Company will specifically reserve for or charge-off the excess of the loan amount over the amount of the appraisal. In certain cases the Company may establish a larger reserve due to knowledge of current market conditions or the existence of an offer for the collateral that will facilitate a more timely resolution of the loan. The Company generally follows a policy of not extending maturities on non-performing loans under existing terms. Certain performing loans that have displayed some inherent weakness in the underlying collateral values, an inability to comply with certain loan covenants which do not affect the performance of the credit or other identified weakness may have their terms extended on an exception basis. Maturity date extensions only occur under revised terms that place the Company in a better position to fully collect the loan under the contractual terms and /or terms at the time of the extension that may eliminate or mitigate the inherent weakness in the loan. These terms may incorporate, but are not limited to additional assignment of collateral, si gnificant balance curtailments/liquidations and assignments of additional project cash flows. Documented or demonstrated guarantees may be a consideration in the extension of loan maturities. As a general matter, the Company does not view extension of a loan to be a satisfactory approach to resolving non-performing credits. Loans that have their terms restructured (e.g., interest rates, loan maturity date, payment and amortization period, etc.) in circumstances that provide payment relief or other concessions to a borrower experiencing financial difficulty are considered trouble debt restructured loans. All restructurings that constitute concessions to a troubled borrower are considered impaired loans that may either be in accruing status or non-accruing status. Non-accruing restructured loans may return to accruing statu s provided there is a sufficient period of payment performance in accordance with the restructure terms . Loans may be removed from the restructured category if the borrower is no longer experiencing financial difficulty, a re-underwriting event took place and the revised loan terms of the subsequent restructuring agreement are considered to be consistent with terms that can be obtained in the credit market for loans with comparable credit risk . At December 31, 2017 , restructured loans totaled $9.0 million, of which $2.8 million were accruing and $6.2 million wer e non-accruing. The Company had no commit me nts to lend additional funds on loans that have been restructured at December 31, 2017 . Restructured loans at December 31, 2016 total ed $9 .2 million, of which $2 .5 million were accruing and $6.7 million were non-accruing. Commitment s to lend additional funds on loans that have been restructured at December 31, 2016 amounted to $0.1 million.

The credit quality indicators used are dependent on the portfolio segment to which the loan relat es. Commercial loans and non-commercial loans have different credit quality indicators as a result of the methods used to monitor each of these loan segments. The credit quality indicators for commercial loans are developed through review of individual borrowers on an ongoing basis. Each borrower is evaluated at least annually with more frequen t evaluation of more seve rely criticized loans . The indicators represen t the rating for loans as of the date presented based on the most recent credit review performed. These credit quality indicators are defined as follows: Pass - A pass rated credit i s 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 m ay 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 character ized 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 collec tion 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.

Modifications consisted principally of interest rate concessions. No modifications resulted in the reduction of the principal in the associated loan balances. Restructured loans are subject to periodic credit reviews to determine the necessity and adequacy of a specific loan loss allowance based on the collectability of the recorded investment in the restructur ed loan. Loans restructured during 2017 have specific reserves of $0.2 million at December 31, 2017 . For the year ended December 31, 2016 , the Company restructured $0.6 million in loans.

The Omnibus Stock Plan expired during the second quarter of 2015 but has outstanding options that may still be exercised. The Omnibus Incentive Plan is described in the following paragraph. The Company’s Omnibus Incentive Plan was approved on May 6, 2015 and provides for the granting of non-qualifying stock options to the Company’s directors, and incentive and non-qualifying stock options, stock appreciation rights , restricted stock grants, restricted stock units and performance awards to selected key emp loyees on a periodic basis at the discretion of the board. The Omnibus Incentive Plan authorizes the issuance of up to 1,500 ,000 shares of common stock, of which 1, 3 40 , 359 shares are availa ble for issuance at December 31, 2017 , has a term of ten years, an d 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 a nd must be exercised within seven to ten years from the date of grant. The exercise price of stock options must be paid for in full in cash or shares of common stock, or a combination of both. 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 op tion exercises. The fair values of all of the options granted for the periods indicated have been estimated using a binomial option-pricing model with the weighted-average assumptions for the years ended December 31 are presented in the following table: 2017 2016 2015 Dividend yield 2.45 % 3.48 % 3.40 % Weighted average expected volatility 40.27 % 41.54 % 42.98 % Weighted average risk-free interest rate 2.14 % 1.42 % 1.42 % Weighted average expected lives (in years) 5.67 5.71 5.42 Weighted average grant-date fair value $13.42 $7.75 $7.63 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. The Company recognized forfeitures as they occur. Compensation expense is recognized on a straight-line basis over the vesting period of the respective stock option or restricted stock grant. Compensati on expense of $2.1 million, $1.9 million, and $1.9 million was recognized for the years ended December 31, 2017 , 2016 and 2015 , respectively, related to the award s of stock options and restricted stock grants.

The total of unrecognized com pensation cost related to stoc k options was approximately $0.2 million as of December 31, 2017 . That cost is expected to be recognized over a weighted ave rage period of approximately 1.8 years. The total of unrecognized compensation cost related to re stric ted stock was approximately $4. 3 million as of December 31, 2017 . That cost is expected to be recognized over a weighted ave rage period of approximately 3. 0 years . The fair value of the options vested during the years ended December 31, 2017 , 2016 and 2015 , was $0.2 million, $0.2 million and $0.2 million, respectively.

An additional 6,873 shares of performance ba sed restricted stock grants were also approved as part of the restricted shares granted in the first quarter. The performance shares are subject to cliff vesting after three years based on the relative performance of the Company’s stock in comparison to a selected peer group.

PENSION, PROFIT SHARING, AND OTHER EMPLOYEE BENEFIT PLANS	Note 13 – Pension, Profit Sharing, and Other Employee Benefit Plans Defined Benefit Pension Plan The Company has a qualified, noncontributory, defined benefit pension plan (the “Plan”) covering substantially all employees. All benefit accruals for employees were frozen as of December 31, 2007 based on past service and thus future salary increases and additional years of service will 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 de ems 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. The Plan’s funded status at December 31 is as follows: (In thousands) 2017 2016 Reconciliation of Projected Benefit Obligation: Projected obligation at January 1 $ 40,783 $ 39,416 Interest cost 1,640 1,657 Actuarial loss (gain) (32) 251 Benefit payments (1,945) (1,248) Increase related to change in assumptions 2,995 707 Projected obligation at December 31 43,441 40,783 Reconciliation of Fair Value of Plan Assets: Fair value of plan assets at January 1 36,020 30,683 Actual return on plan assets 4,971 755 Contribution 2,200 5,830 Benefit payments (1,945) (1,248) Fair value of plan assets at December 31 41,246 36,020 Funded status at December 31 $ (2,195) $ (4,763) Accumulated benefit obligation at December 31 $ 43,441 $ 40,783 Unrecognized net actuarial loss $ 12,487 $ 13,689 Net periodic pension cost not yet recognized $ 12,487 $ 13,689 Weighted-average assumptions used to determine benefit obligations at December 31 are presented in the following table: 2017 2016 2015 Discount rate 3.65% 4.15% 4.26% 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) 2017 2016 2015 Interest cost on projected benefit obligation $ 1,640 $ 1,657 $ 1,629 Expected return on plan assets (1,985) (1,614) (1,622) Recognized net actuarial loss 1,181 1,164 1,032 Net periodic benefit cost $ 836 $ 1,207 $ 1,039 Weighted-average assumptions used to determine net periodic benefit cost for years ended December 31 are presented in the following table: 2017 2016 2015 Discount rate 4.15% 4.26% 3.91% Expected return on plan assets 6.00% 5.00% 5.00% Rate of compensation increase N/A N/A N/A The expected rate of return on assets of 6 .00% reflects the Plan’s predominant investment of assets in equity securities and an analysis of the average rate of return of the S&P 500 index and 10 year U.

The investment policy is designed to provide limits on risk that is undertaken by the investment managers both in terms of market volatility of the portfolio and the quality of the individual assets that are held in the portfolio. The investment policy statement focuses on the following areas of concern: preservation of capital, diversific ation, risk tolerance, investment duration, rate of return, liquidity and investment management costs. The Company has constituted the Retirement Plans Investment Committee (“RPIC”) in part to monitor the investments of the Plan as well as to recommend to executive management changes in the Investment Policy Statement which governs the Plan’s investment operations. These recommendations include asset allocation changes based on a number of factors including the investment ho rizon for the Plan. The Company uses outside third parties to advise RPIC on the Plan’s investment matters . Investment strategies and asset allocations are based on careful consideration of plan liabilities, the plan’s funded status and the Company’s financial condition. Investment perf ormance and asset allocation are measured and monitored on an ongoing basis. During 2017, management initiated a shift in target allocations for plan assets towards fixed income securities in order to more closely align expected cash outflows with its funding source. This asset allocation has been set after taking into consideration the Plan’s current frozen status and the possibility of partial plan terminations over the intermediate term. Market volatility risk is controlled by limiting the asset allocation of the most volatile asset class, equi ties, to no more than 70% of the portfolio and by ensuring that there is sufficient liquidity to meet distribution requirements from the portfolio without disrupting long-term assets. Diversification of the equity portion of the portfolio is controlled by limiting the value of any initial acquisition so that it does not exceed 5% of the market value of the portfolio when purchased. The policy requires the sale of any portion of an equity position when its value exceeds 10% of the portfolio. Fixed income market volatility risk is managed by limiting the term of fixed income investments to five years. Fixed income investments must carry an “A” or better rating by a recognized credit rating agency. Corporate debt of a single issuer may not exceed 10% of th e market value of the portfolio. The investment in derivative instruments such as “naked” call options, futures, commodities, and short selling is prohibited. Investment in equity index funds and the writing of “covered” call options (a conservative stra tegy to increase portfolio income) are permitted. Foreign currency-denominated debt instruments are not permitted. At December 31, 2017 , management is of the opinion that there are no significant concentrations of risk in the assets of the plan with re spect to any single entity, industry, country, commodity or investment fund that are not otherwise mitigated by FDIC insurance available to the participants of the plan and collateral pledged for any such amount that may not be covered by FDIC insurance. Investment performance is measured against industry accepted benchmarks. The risk tolerance and asset allocation limitations imposed by the policy are consistent with attaining the rate of return assumptions used in the actuarial funding calculations. The RPIC committee meets quarterly to review the activities of the investment managers to ensure adherence with the Investment Policy Statement.

Such factors include the investment performance of the plan assets in the current economy and, since the plan is currently frozen, the remaining investment horizon of the pl an. After consideration of these factors, the Company made a contribution of $2 .2 million in 2017 . M anagement continues to monitor the funding level of the pension plan and may make co ntributions as necessary during 2018 . Estimated Future Benefit Payments Benefit payments, which reflect expected future service, as appropriate, that are expected to be paid for the years ending December 31 are presented in the following table: Pension (In thousands) Benefits 2018 $ 2,510 2019 2,000 2020 1,800 2021 2,560 2022 2,450 2023 - 2027 13,890 Cash and Deferred Profit Sharing Plan The Sandy Spring Ban k 401(k) Plan includes a 401(k) provision with a Company match. The 401(k) provision is voluntary and covers all eligible employees after ninety days of service. Employees contributing to the 401(k) provision receive a matching contribution of 100% of the first 3% of compensation and 50% of the next 2% of compensation subject to employee contribution limitations. The Company matching contribution vests immediatel y. The Plan permits employees to purchase shares of Sandy Spring Bancorp, Inc. common stock with their 401(k) contributions, Company match, and other contributions under the Plan. The Company’s matching contribution to the 401(k) Plan that are included i n no n-interest expenses totaled $2.0 million, $2.0 million, and $2.0 million in 2017 , 2016 and 2015 , respectively. Executive Incentive Retirement Plan The Executive Incentive Retirement Plan is a non-qualified deferred compensation defined contribution plan that provides for contributions to be made to the participants’ plan accounts based on the attainment of a level of financial performance compared to a selected group of peer banks. This level of performance is determined annually by the board of directors. Benefit costs related to the Plan included in non-interest expense for 2017 , 2016 and 2015 were $0.4 million, $0. 3 million, and $0.2 million, respectively.

The Act reduces the U.S. federal corporate tax rate from 35% to 21 % for years beginning on or after January 1, 2018. The Company recorded a provisional amount to deferred tax expense of $5. 5 million, which was primarily due to a re-measurement of deferred tax assets and liabilities at the newly enacted rate. Certain deferred tax assets and liabilities were re-measured based on the rates at which they are expected to reverse in the future, which is generally 21%. The Company is analyzing certain aspects of the Act along with the recently issued FASB guidance on reclassification of the tax effects stranded in OCI , which could potentia lly affect the measurement of these balances or give rise to new deferred tax amounts.

Financial Instruments With Off- Balance Sheet Risk and Derivatives [Abstract]
FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK AND DERIVATIVES	NOTE 18 – Financial Instruments with Off-balance Sheet Risk and Derivatives 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, inv entory and accounts receivable. Commitments do not necessarily repr esent 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) 2017 2016 Commercial real estate development and construction $ 390,646 $ 334,552 Residential real estate-development and construction 130,751 97,524 Real estate-residential mortgage 18,238 22,970 Lines of credit, principally home equity and business lines 1,044,949 949,939 Standby letters of credit 62,937 68,748 Total Commitments to extend credit and available credit lines $ 1,647,521 $ 1,473,733 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 swap positions are offset to minimize the potential impact on the Company’s financial state ments. Credit risk exists if the borrower’s collateral or financial condition indicates that the underlying collateral or financial condition of the borrower makes it probable that amounts due will be uncollectible. Any amounts due to the Company will be expected to be collected from the borrower. Management reviews this credit exposure on a monthly basis. At December 31, 2017 and 2016 , all loans associated with the swap agreements were determined to be “pass” rated credits as provided by regulato ry guidance and therefore no component of credit loss was factored into the valuation of the swaps. A summary of the Company’s interest rate swaps at December 31 for the years indicated is included in the following table: 2017 Notional Estimated Years to Receive Pay (Dollars in thousands) Amount Fair Value Maturity Rate Rate Interest Rate Swap Agreements: Pay Fixed/Receive Variable Swaps $ 8,894 $ (707) 5.2 2.54 % 5.42 % Pay Variable/Receive Fixed Swaps 8,894 707 5.2 5.42 % 2.54 % Total Swaps $ 17,788 $ - 5.2 3.98 % 3.98 % 2016 Notional Estimated Years to Receive Pay (Dollars in thousands) Amount Fair Value Maturity Rate Rate Interest Rate Swap Agreements: Pay Fixed/Receive Variable Swaps $ 9,433 $ (1,010) 6.3 1.86 % 5.38 % Pay Variable/Receive Fixed Swaps 9,433 1,010 6.3 5.38 % 1.86 % Total Swaps $ 18,866 $ - 6.3 3.62 % 3.62 % The estimated fair value of the swaps at December 31 for the periods indicated in the table above were recorded in other assets and other liabilities. The associated net gains and losses on the swaps are recorded in other non-interest income.

Commitments and Contingencies Disclosure [Abstract]
LITIGATION	Note 19 - litigation The Company and its subsidiaries are subject in the ordinary course of business to various pending or threatened legal proceedings in which claims for monetary damages are asserted. After consultation with legal counsel, management does not anticipate that the ultimate liability, if any, arising out of these legal matters will have a material adverse effect on the Company’s financial condition, operating results or liquidity. In 2014, as a result of an adverse jury verdi ct the Company accrued $ 6.5 million for litigation expenses associated with the actions of an employee from an institution that was acquired in 2012. During 2015, as a result of a settlement of all claims, including claims for a contribution from its insu rer relating to this litigation, the Company reversed $ 4.5 million in previously accrued litigation expenses.

FAIR VALUE

FAIR VALUE	12 Months Ended

Fair Value Disclosures [Abstract]
FAIR VALUE	Note 20 – 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 co mmitment. 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 o f 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 hiera rchy 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 ar e 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, o r 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 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 and mortgage-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 coupl ed 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 avail able 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 de termine 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 sec urities. 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 ab ility 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. Trust preferred securities In active markets, these types of instruments are valued based on quoted market prices that are readily accessible at the measurement date and are classified within Level 1 of the fair value hierarchy. Positions that are not traded in active markets or are subject to transfe r restrictions are valued or adjusted to reflect illiquidity and/or non-transferability, and such adjustments are generally based on available market evidence. In the absence of such evidence, management uses a process that employs certain assumptions to determine the present value. For furt her information, refer to Note 3 – Investments. Positions that are not traded in active markets or are subject to transfer restrictions are classified within Level 3 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 instrum ents 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 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: 2017 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 $ - $ 9,848 $ - $ 9,848 Investments available-for-sale: U.S. government agencies - 106,568 - 106,568 State and municipal - 312,253 - 312,253 Mortgage-backed - 300,040 - 300,040 Corporate debt - - 9,432 9,432 Trust preferred - - 1,002 1,002 Marketable equity securities - 212 - 212 Interest rate swap agreements - 707 - 707 Liabilities Interest rate swap agreements $ - $ (707) $ - $ (707) 2016 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 $ - $ 13,222 $ - $ 13,222 Investments available-for-sale: U.S. government agencies - 121,790 - 121,790 State and municipal - 287,684 - 287,684 Mortgage-backed - 312,711 - 312,711 Corporate debt - - 9,134 9,134 Trust preferred - - 1,012 1,012 Marketable equity securities - 1,223 - 1,223 Interest rate swap agreements - 1,010 - 1,010 Liabilities Interest rate swap agreements $ - $ (1,010) $ - $ (1,010) The fair value of investments transferred or that are purchased and placed in Level 3 is estimated by discounting the expected future cash flows using the current rates for investments with similar credit ratings and similar remaining maturities. Expected cash flows were projected based on contractual cash flows.

Assets are classified in their entirety based on the lowest level of input that is significant to the fair value measurement: 2017 Quoted Prices in Significant Active Markets Other Significant for Identical Observable Unobservable (In thousands) Assets (Level 1) Inputs (Level 2) Inputs (Level 3) Total Total Losses Impaired loans (1) $ - $ - $ 8,474 $ 8,474 $ (11,806) Other real estate owned - - 2,253 2,253 (158) Total $ - $ - $ 10,727 $ 10,727 $ (11,964) (1) Amounts represent the fair value of collateral for impaired loans allocated to the allowance for loan losses. Fair values are determined using actual market prices (Level 2), independent third party valuations and borrower records, discounted as appropriate (Level 3). 2016 Quoted Prices in Significant Active Markets Other Significant for Identical Observable Unobservable (In thousands) Assets (Level 1) Inputs (Level 2) Inputs (Level 3) Total Total Losses Impaired loans (1) $ - $ - $ 8,981 $ 8,981 $ (10,600) Other real estate owned - - 1,911 1,911 (107) Total $ - $ - $ 10,892 $ 10,892 $ (10,707) (1) Amounts represent the fair value of collateral for impaired loans allocated to the allowance for loan losses. 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, 2017 , impaired loans totaling $20 .8 million were wri tten down to fair value of $16 .8 million as a result of speci fic loan loss allowances of $4.0 million associated with the impaired loans which was included in the allowance for loan losses . Impaired loans totaling $24 .1 million were wri tten down to fair value of $19 .3 million at December 31, 2016 as a result of speci fic loan loss allowances of $4 .8 million associated with the impaired loans. Loan impairment is measured using the present value of expected cash flows, the loan’s observable market price or the fair value of the collateral (less selling costs) if the loans are collateral dependent. Collateral may be real estate and/or business assets including equipment, inventory an d/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 knowledge, changes in market conditions from the time of valuation, and/or management’s expertise and knowledge of the client and client’s business. Impaired loans are reviewed and evalua ted on at least a quarterly basis for additional impairment and adjusted accordingly, based on the factors identified above. Valuation techniques are consistent with those techniques applied in prior periods. Other real estate owned (“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. The estimated fair value for other real estate owned 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 subseque nt 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 about financial instruments for which it is practicable to estimate the value, whether or not such financial instruments are recognized on the balance sheet. 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 availabl e, 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 ca sh flows and estimated discount rates. 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 individu al financial assets and liabilities, and should not be considered an indication of the fair value of the Company. 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 2017 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 $ 45,518 $ 45,518 $ - $ 45,518 $ - Loans, net of allowance 4,268,991 4,320,719 - - 4,320,719 Other assets 95,730 95,730 - 95,730 - Financial Liabilities Time deposits $ 688,951 $ 684,139 $ - $ 684,139 $ - Securities sold under retail repurchase agreements and federal funds purchased 119,359 119,359 - 119,359 - Advances from FHLB 765,833 769,860 - 769,860 - Fair Value Measurements 2016 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 Investments held-to-maturity and other equity securities $ 46,094 $ 46,094 $ - $ 46,094 $ - Loans, net of allowance 3,883,741 3,933,700 - - 3,933,700 Other assets 93,328 93,328 - 93,328 - Financial Liabilities Time deposits $ 586,039 $ 584,868 $ - $ 584,868 $ - Securities sold under retail repurchase agreements and federal funds purchased 125,119 125,119 - 125,119 - Advances from FHLB 790,000 800,756 - 800,756 - Subordinated debentures 30,000 29,985 - - 29,985 The following methods and assumptions were used to estimate the fair value of each category of financial instruments for which it is practicable to estimate that value: Cash and temporary investments: The carrying amounts of cash and cash equivalents approximate their fair value and have been excluded from the table above. Investments: The fair value of marketable securities is based on quoted market prices, prices quoted for similar instruments, and prices obtained from independent pricing services. Loans: For certain categories of loans, such as mortgage, installment and commercial loans, the fair value is estimated by discounting the expected future cash flows using the current rates at which similar loans would be made to borrowers with similar credit ratings and similar remaining maturities. Expected cash flows were projected based on contractual cash flows, adjusted for estimated prepayments. Accrued interest receivable: The carrying value of accrued interest receivable approximates fair val ue due to the short-term duration and has been excluded from the table above. Other assets: The investment in bank-owned life insurance represents the cash surrender value of the policies at December 31, 2017 and 2016 , respectively, as determined b y each insurance carrier. The carrying value of accrued interest receivable approximates fair values due to the short-term duration. Deposits: The fair value of demand, money market savings and regular savings deposits, which have no stated maturity , were considered equal to their carrying amount, representing the amount payable on demand. While management believes that the Bank’s core deposit relationships provide a relatively stable, low-cost funding source that has a substantial intangible value s eparate from the value of the deposit balances, these estimated fair values do not include the intangible value of core deposit relationships, which comprise a significant portion of the Bank’s deposit base. Short-term borrowings: The carrying values of short-term borrowings, including overnight, securities sold under agreements to repurchase and federal funds purchased approximates the fair values due to the short maturities of those instruments. Long-term borrowings: The fair value of the Federal Home Loan Bank of Atlanta advances and subordinated debentures was estimated by computing the discounted value of contractual cash flows payable at current interest rates for obligations with similar remaining terms. The Company's credit risk is not material to calculation of fair value because these borrowings are collateralized. The Company classifies advances from the Federal Home Loan Bank of Atlanta within Level 2 of the fair value hierarchy since the fair value of such borrowings is based on rates curren tly available for borrowings with similar terms and remaining maturities. Subordinated debentures we re classified as Level 3 in the fair value hierarchy due to the lack of market activity of such instruments. Accrued interest payable: The carrying value o f accrued interest payable approximates fair value due to the short-term duration and has been excluded from the previous table.

Banking and Thrift [Abstract]
REGULATORY MATTERS	Note 22 – 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 B ank 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 classifi cations 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 m inimum 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, 2017 and 2016 , the capital levels of the Company and the Bank substantially exceeded all applicable capital adequacy requirements. As of December 31, 2017 , 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 a s 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 managemen t believes have changed the Bank's category.

Pending Business Combination [Abstract]
Business Combination Pending [Text Block]	Note 25 – acquisition of Washingtonfirst bankshares, inc. On January 1, 2018 (“Acquisition Date”), the Company completed its acquisition of WashingtonFirst Bankshares, Inc. (“WashingtonFirst ”) in a transaction valued at approximately $452 million in the aggregate, based on the Company’s volume-weighted average share price of $39.5051. Volume-weighted average share price represents a volume-weighted average price of the Company’s common stock on the Nasdaq Global Select Market, for the twenty trading day period ending on the fifth trading day before the closing of the acquisition. As of the Acquisition Date, WashingtonFirst was merged into the Company and WashingtonFirst’s wholly-owned subsidia ry, WashingtonFirst Bank, was merged with and into Sandy Spring Bank. The Company issued an aggregate of 11,446,441 shares of the Company’s common stock in the transaction. At the effective date of the acquisition, Sandy Spring shareholders owned approxi mately 67.7% of the combined company and WashingtonFirst’s shareholders owned approximately 32.3% of the combined company. WashingtonFirst was headquartered in Reston, Virginia, had 19 community banking offices throughout the Washington D.C. metropolitan region and more than $2.1 billion in assets as of December 31, 2017. In addition, WashingtonFirst provided wealth management services through its subsidiary, 1st Portfolio Wealth Advisors, and mortgage banking services through the bank’s subsidiary, Washi ngtonFirst Mortgage Corporation. The acquisition of WashingtonFirst is being accounted for as a business combination using the acquisition method of accounting and, accordingly, assets acquired, liabilities assumed, and consideration paid are recorded a t estimated fair values on the Acquisition Date. Due to complexity of the fair value analysis and relatively short time frame between the Acquisition Date and financial statements issuance date, the valuation of acquired assets and assumed liabilities was not final as of the financial statements issuance date. The provisional amount of goodwill recognized was approximately $264 million. The estimated fair values of the acquired assets and assumed liabilities will be subject to refinement as additional infor mation relative to closing date fair values becomes available. Any subsequent adjustments to the fair values of acquired assets and liabilities assumed, identifiable intangible assets, or other purchase accounting adjustments will result in adjustments to goodwill within the first 12 months following the closing date of acquisition. We anticipate to finalize the valuation by the end of the first quarter of 2018.

Services to individuals and businesses include accepting deposits, extending real estate, consumer and commercial loans and lines of cred it, equipment leasing, general insurance, personal trust, and investment and wealth management servi ces. The Company operates in central Maryland, Northern Virginia, and the greater Washington D.C. market. The Company offers investment and wealth manageme nt services through the Bank’s subsidiary, West Financial Services. Insurance products are available to clients through Sandy Spring Insurance, and Neff & Associates, which are agencies of Sandy Spring Insurance Corporation.
Basis of Presentation	Basis of Presentation The ac counting 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 reclassifications have been made to prior period amounts to conform to the current period pre sentation. 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, Sa ndy Spring Bank and its subsidiaries, Sandy Spring Insurance Corporation and West Financial Services, Inc. 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, and affect the reported am ounts 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 loan losses and the related allowance, determination of impa ired loans and the related measurement of impairment, potential impairment of goodwill or other intangible assets, valuation of investment securities and the determination of whether impaired securities are other-than-temporarily impaired, valuation of oth er 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 pe nsion expense and the related liability.
Assets Under Management [Policy Text Block]	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 balance sheets. 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 inc lude cash and due from banks, federal funds sold and interest-bearing deposits with banks (items with an original maturity of three months or less).
Residential Mortgage Loans Held For Sale [Policy Text Block]	Residential Mortgage Loans Held for Sale The Company engages in sales of residential mortgage loans origin ated 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), as permitted by current accounting standards. 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 Compa ny'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 fo r impairment on a periodic basis.
Investments Held-to-maturity [Policy Text Block]	Investments Held-to-Maturity Investments held-to-maturity represents securities which the Company has the ability and positive intent to hold until maturity. These securities are recorded at cost at the time of acq uisition. The carrying values of investments held-to-maturity are adjusted for premium amortization and discount accretion to the maturity date on the effective interest method. Related interest and dividends are included in interest income. Declines in t he fair value of individual held-to-maturity investments below their cost that are other-than-temporary result in write-downs of the individual securities to their fair value. Factors that may affect the determination of whether other-than-temporary impai rment (“OTTI”) has occurred include a downgrading of the security below investment grade by the rating agency or due to potential default, a significant deterioration in the financial condition of the issuer, or that management would not have the ability t o hold a security for a period of time sufficient to allow for any anticipated recovery in fair value. During 2016, all investments held-to-maturity were transferred to investments available-for-sale. Accordingly, acquisitions of investments in the futur e will not be classified as held-to-maturity.
Investments Available-for-Sale [Policy Text Block]	Investments Available-for-Sale Marketable equity securities and 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 unrealiz ed 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 carrying values 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 dividends are included in interest income . Declines in the fair value of individual available-for-sale securities below their cost that are other-than-temporary (“OTTI”) result in write-downs of the individual securities to their fair value. Factors affecting the determination of whether other- than-temporary 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, or a change in management’s intent and ability to hold a security for a period of time sufficient to allow for any anticipated recovery in fair value.
Other Equity Securities [Policy Text Block]	Other Equity Securities Other equity securities include Federal Reserve stock, Federal Home Loan Bank of Atlanta stock and other equities that are considered restricted as to marketability and recorded at cost. These securities are carried at cost and evaluated for impairment each reporting period.
Loans And Lease Financing Receivables [Policy Text Block]	Lo an Financing Receivables The Company’s financing receivables consist primarily of loans that are stated at their principal balance outstanding net of any unearned income and deferred fees and costs. Interest income on loans is accrued at the contractual ra te based on the principal 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 in terest payment or portion thereof, the amount reported as delinquent is the outstanding principal balance of the loan. Loans , except for consumer 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 a mounts 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 w hen they are four months past due. Loans designated as non-accrual have all previously accrued but unpaid interest reversed. Payments received on non-accrual loans when doubt about the ultimate collectability of the principal no longer exists may have th eir interest payments recorded as interest income on a cash basis or using the cost-recovery method with all payments applied to reduce the outstanding principal until the loan returns to accrual status. Loans may be returned to accrual status when all pr incipal and interest amounts contractually due are brought current and future payments are reasonably assured. Large groups of smaller balance homogeneous loans are not individually evaluated for impairment and include lease financing receivables, residen tial permanent and construction mortgages and consumer installment loans. All other loans are considered non-homogeneous and are evaluated for impairment if they are placed in non-accrual status. Loans are determined to be impaired when, based on availab le information, it is probable that the Company may not collect all principal and interest payments according to contractual terms. Factors considered in determining whether a loan is impaired include: the financial condition of the borrower; reliability a nd sources of the cash flows; absorption or vacancy rates; and deterioration of related collateral. The impairment of a loan is measured based on the present value of expected future cash flows discounted at the loan's original effective interest rate, or as permitted, the impairment may be measured based on a loan’s observable market price or the fair value of the collateral less cost to sell. The majority of the Company’s impaired loans are considered to be collateral dependent and impairment is meas ured by determining the fair value of the collateral using third party appraisals 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. The Company may receive updated appraisals which contradict the preliminary determination of fai r value used to establish a specific allowance on a loan. In these instances the specific allowance is adjusted to reflect the Company’s evaluation of the 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 charge d-off loans are accounted for under the cost-recovery method. Under this method, all payments are applied on a cash basis to reduce the entire outstanding principal, then to recognize a recovery of all previously charged-off amounts before interest income may be recognized. Based on the impairment evaluation, if the Company determines an estimable loss exists, a specific allowance will be established for that loan. Once a loss has been confirmed, the loan is charged-down to its estimated net realizable v alue. Interest income on impaired loans is recognized using the same method as non-accrual loans, with the exception of loans that are considered troubled debt restructurings. Loans considered to be troubled debt restructurings (“TDRs”) are loans that h ave their terms restructured (e.g., interest rates, loan maturity date, payment and amortization period, etc.) in circumstances that provide payment relief to a borrower experiencing financial difficulty. All restructured loans are considered impaired loan s and may either be in accruing status or non-accruing status. Non-accruing restructured loans may return to accruing status provided doubt has been removed concerning the collectability of principal and interest as evidenced by a sufficient period of pay ment performance in accordance with the restructured terms. Loans may be removed from the restructured category if the borrower is no longer experiencing financial difficulty, a re-underwriting event took place and the revised loan terms of the subsequent restructuring agreement are considered to be consistent with terms that can be obtained in the credit market for loans with comparable risk. Management uses relevant information available to make the determination on whether loans are impaired in accor dance with GAAP. However, the determination of whether loans are impaired and the measurement of the impairment requires significant judgment, and estimates of losses inherent in the loan portfolio can vary significantly from the amounts actually observed.
Allowance For Loan and Lease Losses [Policy Text Block]	Allowance for Loan Losses The allowance for loan losses (“allowance” or “ALL ”) represents an amount which, in management's judgment, is adequate to absorb the probable estimate of losses that may be sustained on outstanding loans at the balance sheet dat e based on the evaluation of the size and current risk characteristics of the loan portfolio. The allowance is reduced by charge-offs, net of recoveries of previous losses, and is increased or decreased by a provis ion or credit for loan losses, which is r ecorded as a current period operating expense. The allowance is based on the basic principle that a loss be accrued when it is probable that the loss has occurred and the amount of the loss can be reasonably estimated. Determination of the adequacy of t he allowance is inherently complex and requires the use of significant and highly subjective estimates. The reasonableness o f the allowance is reviewed periodically by the Risk Committee of the board of directors and formally approved quarterly by that sa me committee of the board. The Company’s methodology for estimating the allowance includes a general component reflecting historical losses, as adjusted, by loan portfolio segment, and a specific component for impaired loans. There were no changes in the Company’s allowance policies or methodology from the prior year. The general component is based upon historical loss experience by each portfolio segment measured, over the prior eight quarters weighted equally . The historical loss experience is suppleme nted to address various risk characteristics of the Company’s loan portfolio including: trends in delinquencies and other non-performing loans; changes in the risk profile related to large loans in the portfolio; changes in the categories of loans comprising the loan portfolio; concentrations of loans to specific industry segments; changes in economic conditions on both a local and national level; changes in the Company’s credit administration and loan portfolio management processes; and the quality of the Company’s credit risk identification processes. The general component is calculated in two parts based on an internal risk classification of loans within each portfolio segment. Reserves on loans considered to be “classified” under regulatory guidance are calculated separately from loans considered to be “pass” rated under the same guidance. This segregation allows the Company to monitor the allowance component applicable to higher risk loans separate from t he remainder of the portfolio in order to better manage risk and reasonably determine the sufficiency of reserves. Integral to the assessment of the allowance process is an evaluation that is performed to determine whether a specific allowance on an impai red credit is warranted. For the particular loan that may have potential impairment, an appraisal will be ordered depending on the time elapsed since the prior appraisal, the loan balance and/or the result of the internal evaluation. The Company typicall y relies on current (12 months old or less) third party appraisals of the collateral to assist in measuring impairment. In the cases in which the Company does not rely on a third party appraisal, an internal evaluation is prepared by an approved credit off icer. A current appraisal on large loans is usually obtained if the appraisal on file is more than 12 months old and there has been a material change in market conditions, zoning, physical use or the adequacy of the collateral based on an internal evaluat ion. The Company’s policy is to strictly adhere to regulatory appraisal standards. If an appraisal is ordered, no more than a 30 day turnaround is requested from the appraiser, who is selected by Credit Administration from an approved appraiser list. Afte r receipt of the updated appraisal, the assigned credit officer will recommend to the Chief Credit Officer whether a specific allowance or a charge-off should be taken. When losses are confirmed, a charge-off is taken that is at least in the amount of the collateral deficiency as determined by the independent third party appraisal. Any further collateral deterioration results in either further specific reserves being established or additional charge-offs. The Chief Credit Officer has the authority to appr ove a specific allowance or charge-off between monthly credit committee meetings to ensure that there are no significant time lapses during this process. The portion of the allowance representing specific allowances is established on individually impaire d loans. As a practical expedient, for collateral dependent loans, the Company measures impairment based on the net realizable value of the underlying collateral. For loans on which the Company has not elected to use a practical expedient to measure impair ment, the Company will measure impairment based on the present value of expected future cash flows discounted at the loan’s effective interest rate. In determining the cash flows to be included in the discount calculation the Company considers the followi ng factors that combine to estimate the probability and severity of potential losses: the borrower’s overall financial condition; resources and payment record; demonstrated or documented support available from financial guarantors; and the adequacy of col lateral value and the ultimate realization of that value at liquidation. 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. Howe ver, the determination of the allowance requires significant judgment, and estimates of proba ble losses in the loan portfolio can vary significantly from the amounts actually observed. While management uses available information to recognize inherent losse s, future additions to the allowance may be necessary based on changes in th e loans comprising the portfolio and changes in the financial condition of borrowers, such as may result from changes in economic conditions. In addition, various regulatory age ncies, as an integral part of their examination process, and independent consultants engaged by the Company, period ically review the loan portfolio and the allowance. Such review may result in additional provisions based on management’s judgments of infor mation available at the time of each examination.
Premises and Equipment [Policy Text Block]	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 o ver 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.
Goodwill And Other Intangible Assets [Policy Text Block]	Goodwill and Other I ntangible 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 circums tances 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 u nits 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. The Company tests for impairment of goodwill as of October 1 of each year, and again at any quarter-end if any triggering events occur during a quarter that may affect goodwill. Examples of such events include, but are not limited to, adverse action by a regulator or a los s of key personnel. Determining the fair value of a reporting unit requires the Company to use a degree of subjectivity. Current accounting guidance provides the option to first assess qualitative factors to determine whether the existence of events o r 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 f actors, if it is determined that the fair value of a reporting unit is not less than the carrying value, then performing the two-step impairment process, previously required, is unnecessary. However, if it is determined that the carrying value exceeds the fair value the first step, described above, of the two-step process must be performed. At December 31, 2017 and 2016 there was no evidence of impairment of goodwill or intangibles in any of the Company’s reporting units. Other intangible assets re pr esent purchased assets that lack physical substance but can be distinguished from goodwill because of contractual or other legal rights or because the asset is capable of being sold or exchanged either on its own or in combination with a related contract, asset, or liability. Other intangible assets have finite lives and are reviewed for impairment annually. These assets are amortized over t heir estimated useful lives either on a straight-line or sum-of-the-years basis over varying periods that initially d id not exceed 15 years.
Other Real Estate Owned [Policy Text Block]	Other Real Estate Owned (“OREO”) 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 loan 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 [Policy Text Block]	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 on 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. Mo rtgage l oan 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 S ale 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 comm itments, 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 de livery 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 hedg e the closed loan inventory are recognized at fair value on 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 statement s 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 loa n 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 fa ir value in other assets or other liabilities. 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. Furthe r discussion of the Company's financial derivatives is set forth in Note 18 to the Consolidated Financial Statements.
Off-Balance Sheet Credit Risk [Policy Text Block]	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 facilit ies 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 Co mpany’s credit policies. Potential exposure to loss for unfunded letters of credit if deemed necessary would be recorded in other liabilities. In the ordinary course of business the Company originates and sells whole loans to a variety of investors. Mor tgage 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 obl igated 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 repurchas e loans and the associated losses incurred. This information is applied to determine an estimated recourse reserve that is recorded in other liabilities.
Valuation of Long-Lived Assets [Policy Text Block]	Valuation of Long-Lived Assets The Company reviews long-lived assets and certain identifiable intang ible 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 a comparing the carrying amount of the asset to future undiscounted net cash flows e xpected 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 [Policy Text Block]	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 whe ther 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 inc urred in a sale are recognized and initially measured at fair value.
Insurance Commissions And Fees [Policy Text Block]	Insurance Commissions and Fees Commission revenue is recognized over the term of the coverage period . The Company also receives contingent commissions from insurance companies as addi tional incentive for achieving specified premium volume goals and/or the loss experience of the insurance placed by the Company. Contingent commissions from insurance companies are recognized when determinable, which is generally when such commissions are received.
Advertising Costs [Policy Text Block]	Advertising Costs Advertising costs are expensed as incurred and included in non-interest expenses.
Net Income per Common Share [Policy Text Block]	Net Income per Common Share The Company calculates earnings per common share under the dual class method , which provides that unvested share-ba sed payment awards that contain nonforfeitable 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 h as determined that its outstanding non-vested restricted stock awards are participating securities. Under the dual class method, basic earnings per common share is computed by dividing net earnings allocated to common stock by the weighted-average number of common shares outstanding during the applicable period, excluding outstanding participating securities. Diluted earnings per common share is computed using the weighted-average number of shares determined for the basic earnings per common share comp utation plus the dilutive effect of outstanding stock options and restricted stock using the treasury stock method.
Income Tax [Policy Text Block]	Income Taxes Income tax expense is based on the results of operations, adjusted for permanent differences between items of income or expen se 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 bet ween 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. The Company’s policy is to recognize interest and penalties on income taxes in other non-interest expenses. The Company remains subject to examination for income tax returns by the Internal Revenue Service, a s well as all of the states where it conducts business, for the year s ending after December 31, 2014 . There are currently no examinations in process as of December 31, 2017 .
Pending Accounting Pronouncements	Adopted Accounting Pronouncement The FASB issued Update No. 2016-09 , Improvements to Employee Share-Based Payment Accounting (Topic 718), in March 2016. This guidance requires recognition of all income tax effects of stock awards in the income statement when such awards vest or are settled. In addition, it revises the exist ing guidance to allow employers to withhold more of an employee’s shares to satisfy the employer’s statutory withholding requirements and still qualify for equity accounting treatment. Finally, an entity is now allowed to make an entity-wide accounting pol icy election to either estimate the number or awards that are expected to vest, as required in the current guidance, or account for forfeitures as they occur. The Company adopted this accounting pronouncement prospectively during the first interim period w ithin the current annual period. Adoption of the standard had no material impact on the Company’s financial position, results of operations or cash flows. Pending Accounting Pronouncements The FASB issued Update No. 2017-08, Receivables-Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities , in March 2017. This guidance is intended to eliminate the current diversity in practice with respect to the amortization period for certain purchased callable d ebt securities held at a premium. Under current generally accepted accounting principles (GAAP), entities generally amortize the premium as an adjustment of yield over the contractual life. As a result, upon the exercise of a call on a callable debt securi ty held at a premium, the unamortized premium is recorded as a loss in earnings. The amendments in this update shorten the amortization period for such callable debt securities held at a premium requiring the premium to be amortized to the earliest call da te. This guidance is effective for a public business entity that is a U.S. Securities and Exchange Commission (SEC) filer for its fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The adoption of this standard is not expected to have a material impact on the Company’s financial position, results of operations or cash flows as our current accounting policy for amortization of premium on purchased callable debt securities is in accordance with provisions of ASU 20 17-08 . The FASB issued Update No. 2017-04, Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment , in January 2017. The objective of this guidance is to simplify an entity’s required test for impairment of goodwill by eliminating Step 2 from the goodwill impairment test. In Step 2 an entity measured a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. In computing the implied fair value of goodwill, an entity had to determine the fair value at the impairment date of its assets and liabilities, including any unrecognized assets and liabilities, following a procedure that would be required in determining the fair value of assets acquired an d liabilities assumed in a business combination. Under this Update, an entity should perform its annual or quarterly goodwill impairment test by comparing the fair value of the reporting unit with its carrying amount and record an impairment charge for the excess of the carrying amount over the reporting unit’s fair value. The loss recognized should not exceed the total amount of goodwill allocated to the reporting unit and the entity must consider the income tax effects from any tax deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if applicable. This guidance is effective for a public business entity that is an SEC filer for its annual or any interim goodwill impairment tests in fiscal years begi nning after December 15, 2019. The adoption of this standard is not expected to have a material impact on the Company’s financial position, results of operations or cash flows. The FASB issued Update 2017- 0 1, Business Combinations (Topic 805): Clarifying the Definition of a Business , in January 2017. The objective of this guidance is to clarify the definition of a business to provide entities with assistance in evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The update provides a screen to determine when an integrated set of assets and activities (a “set”) is not a business. The screen requires that when substantially all of the fair value of the gross assets acquired (or disposed of) is concen trated in a single identifiable assets or a group of similar identifiable assets, the set is not a business. The screen thus reduces the number of transactions that need to be further evaluated. If the screen is not met, the amendments in this Update (1) r equire that to be considered a business, a set must include, at a minimum, an input and substantive process that together significantly contribute to the ability to create output and (2) remove the evaluation of whether a market participant could replace m issing elements. The amendments provide a framework to assist entities in evaluating whether both an input and a substantive process are present. The framework includes two sets of criteria to consider that depend on whether a set has outputs. Although out puts are not required for an asset to be a business, outputs generally are a key element of a business; therefore, the Board has developed more stringent criteria for sets without outputs. This guidance was adopted by the Company on January 1, 2018. The ad option of this standard did not have a material impact on the Company’s financial position, results of operations or cash flows and will be considered for future acquisitions . The FASB issued Update No. 2016-15, Statement of Cash Flow (Topic 230): Classif ication of Certain Cash Receipts and Cash Payments , in August 2016. This guidance is intended to reduce the diversity in practice with respect to the presentation and classification of items in the statement of cash flows. This guidance is effective for pu blic business entities for the first interim or annual period beginning after December 15, 2017. The standard’s provisions will be applied using a retrospective transition method to each period presented. An entity may elect early adoption but must adopt a ll of the amendments in the same period. The planned adoption of this standard is not expected to have a material impact on the Company’s financial position, results of operations or cash flows. The FASB issued Update No. 2016-13, Current Expected Credit Losses (CECL) (Topic 326) , in June 2016. This guidance changes the impairment model for most financial assets measured at amortized cost and certain other instruments. Entities will be required to use an expected loss model, replacing the incurred loss mo del that is currently in use. Under the new guidance, an entity will measure all expected credit losses for financial instruments held at the reporting date based on historical experience, current condition and reasonable and supportable forecasts. This w ill result in earlier recognition of loss allowances in most instances. Credit losses related to available-for-sale debt securities (regardless of whether the impairment is considered to be other-than-temporary) will be measured in a manner similar to the present, except that such losses will be recorded as allowances rather than as reductions in the amortized cost of the related securities. With respect to trade and other receivables, loans, held-to-maturity debt securities, net investments in leases and o ff-balance-sheet credit exposures, the guidance requires that an entity estimate its lifetime expected credit loss and record an allowance resulting in the net amount expected to be collected to be reflected as the financial asset. Entities are also requi red to provide significantly more disclosures, including information used to track credit quality by year of origination for most financing receivables. This guidance is effective for public business entities for the first interim or annual period beginnin g after December 15, 2019. The standard’s provisions will be applied as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. Early adoption by public business entities is permitted for the first interim or annual period beginning after December 15, 2018. The Company has established an internal steering committee and engaged an external vendor to assist with implementing required changes to loan loss estimation models, metho dology and processes. Relevant historical data for the development of the methodology in accordance with ASC 326 has been identified. The Company is assessing this guidance to determine its impact on the Company’s financial position, results of operations and cash flows. The FASB issued Update No. 2016-02, Leases (Topic 842) , in February 2016. From the lessee’s perspective, the new standard establishes a right-of-use (ROU) model that requires a lessee to record a ROU asset and a lease liability on the bala nce sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement for lessees. The guidance also eliminates the curr ent real estate-specific provision and changes the guidance on sale-leaseback transactions, initial direct costs and lease executory costs. All entities will classify leases to determine how to recognize lease-related revenue and expense. In applying this guidance entities will also need to determine whether an arrangement contains a lease or service agreement. Disclosures are required by lessees and lessors to meet the objective of enabling users of financials statements to assess the amount, timing, and u ncertainty of cash flows arising from leases. For public entities, this guidance is effective for the first interim or annual period beginning after December 15, 2018. Early adoption is permitted. Entities are required to use a modified retrospective appro ach for leases that exist or are entered into after the beginning of the earliest comparative period in the financial statements. The Company has identified the full population of leases subject to ASC 842 and expects them to meet the definition of operati ng lease. The Company expects minimal impact to its results of operations and is assessing this guidance to determine the impact on the Company’s Consolidated Statements of Condition. The FASB issued Update No. 2016-01, Financial Instruments – (Subtopic 825-10): Recognition and Measurement of Financial Assets and Liabilities” , in January 2016. This guidance requires entities to measure equity investments at fair value and recognize changes on fair value in net income. The guidance also provides a new mea surement alternative for equity investments that do not have readily determinable fair values and don’t qualify for the net asset value practical expedient. Entities will have to record changes in instrument specific credit risk for financial liabilities m easured under the fair value option in other comprehensive income, except for certain financial liabilities of consolidated collateralized financing entities. Entities will also have to reassess the realizability of a deferred tax asset related to an avail able-for-sale debt security in combination with their other deferred tax assets. This simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment. For publ ic entities, the guidance in this update is effective for the first interim or annual period beginning after December 15, 2017. The Company has performed a preliminary evaluation of the provisions of ASU No. 2016-01. Based on this evaluation, the Company h as determined that t he adoption of this standard is not expected to have a material impact on the Company’s financial position, results of operations or cash flows. The FASB issued Update No. 2014-09, Revenue from Contracts with Customers (Topic 606) , in May 2014 that provides accounting guidance for all revenue arising from contracts with customers and affects all entities that enter into contracts to provide goods or services to customers. The guidance also provides for a model for the measurement and r ecognition of gains and losses on the sale of certain nonfinancial assets, such as property and equipment, including real estate. For financial reporting purposes, the standard allows for either full retrospective adoption, meaning the standard is applied to all of the periods presented, or modified retrospective adoption, meaning the standard is applied only to the most current period presented in the financial statements with the cumulative effect of initially applying the standard recognized at the date of initial application. The Company’s revenue is comprised of net interest income and non - interest income. The guidance does not apply to revenue associated with financial instruments, net interest income, mortgage origination and servicing activities, and gains and losses from securities. Accordingly, the majority of the Company’s revenues will not be affected. The following revenue streams were identified to be in scope of ASC 606: 1) wealth management income; 2) insurance agency commissions; 3) bank card fees; and 4) service charges on deposit accounts. The Company adopted the standard on January 1, 2018 and has completed an assessment of the revenue contracts for the revenue streams identified to be in scope . The Company’s accounting policies and revenue recognition principles will not change materially as the principles of ASC 606 are largely consistent with the current revenue recognition practices.

Defined Benefit Plan, Investment Strategies, Investment Fund Category	Investment strategies and asset allocations are based on careful consideration of plan liabilities, the plan’s funded status and the Company’s financial condition. Investment performance and asset allocation are measured and monitored on an ongoing basis. During 2017, management initiated a shift in target allocations for plan assets towards fixed income securities in order to more closely align expected cash outflows with its funding source. This asset allocation has been set after taking into consideration the Plan’s current frozen status and the possibility of partial plan terminations over the intermediate term. Market volatility risk is controlled by limiting the asset allocation of the most volatile asset class, equities, to no more than 70% of the portfolio and by ensuring that there is sufficient liquidity to meet distribution requirements from the portfolio without disrupting long-term assets. Diversification of the equity portion of the portfolio is controlled by limiting the value of any initial acquisition so that it does not exceed 5% of the market value of the portfolio when purchased. The policy requires the sale of any portion of an equity position when its value exceeds 10% of the portfolio. Fixed income market volatility risk is managed by limiting the term of fixed income investments to five years. Fixed income investments must carry an “A” or better rating by a recognized credit rating agency. Corporate debt of a single issuer may not exceed 10% of the market value of the portfolio. The investment in derivative instruments such as “naked” call options, futures, commodities, and short selling is prohibited. Investment in equity index funds and the writing of “covered” call options (a conservative strategy to increase portfolio income) are permitted. Foreign currency-denominated debt instruments are not permitted. At December 31, 2017, management is of the opinion that there are no significant concentrations of risk in the assets of the plan with respect to any single entity, industry, country, commodity or investment fund that are not otherwise mitigated by FDIC insurance available to the participants of the plan and collateral pledged for any such amount that may not be covered by FDIC insurance. Investment performance is measured against industry accepted benchmarks. The risk tolerance and asset allocation limitations imposed by the policy are consistent with attaining the rate of return assumptions used in the actuarial funding calculations. The RPIC committee meets quarterly to review the activities of the investment managers to ensure adherence with the Investment Policy Statement.
Four Zero One K Provision Description	The Sandy Spring Bank 401(k) Plan includes a 401(k) provision with a Company match. The 401(k) provision is voluntary and covers all eligible employees after ninety days of service. Employees contributing to the 401(k) provision receive a matching contribution of 100% of the first 3% of compensation and 50% of the next 2% of compensation subject to employee contribution limitations. The Company matching contribution vests immediately. The Plan permits employees to purchase shares of Sandy Spring Bancorp, Inc. common stock with their 401(k) contributions, Company match, and other contributions under the Plan.
