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”). The Bank offers a broad range of commercial banking, retail banking, mortgage and trust services throughout central Maryland, Northern Virginia and the greater Washington D.C. market through its operation of 44 community offices and six financial centers across the region. The Bank also offers a comprehensive menu of insurance and wealth management services through its subsidiaries, Sandy Spring Insurance Corporation and West Financial Services, Inc. Basis of Presentation The accounting and reporting policies of the Company conform to accounting principles generally accepted in the United States of America (“GAAP”) and prevailing practices within the financial services industry for interim financial information and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and notes required for complete financial statements and prevailing practices within the banking industry. The following summary of significant accounting policies of the Company is presented to assist the reader in understanding the financial and other data presented in this report. Operating results for the three months ended March 31, 2017 are not necessarily indicative of the results that may be expected for any future periods or for the year ending December 31, 2017. In the opinion of management, all adjustments (comprising only normal recurring accruals) necessary for a fair presentation of the results of the interim periods have been included. Certain reclassifications have been made to prior period amounts, as necessary, to conform to the current period presentation. The Company has evaluated subsequent events through the date of the issuance of its financial statements. These statements should be read in conjunction with the financial statements and accompanying notes included in the Company’s 2016 Annual Report on Form 10-K as filed with the Securities and Exchange Commission (“SEC”) on March 3, 2017. There have been no significant changes to the Company’s accounting policies as disclosed in the 2016 Annual Report on Form 10-K. Principles of Consolidation The unaudited condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiary, Sandy Spring Bank and its subsidiaries, Sandy Spring Insurance Corporation and West Financial Services, Inc. Consolidation has resulted in the elimination of all intercompany accounts and transactions. Use of Estimates The preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements, and affect the reported amounts of revenues earned and expenses incurred during the reporting period. Actual results could differ from those estimates. Estimates that could change significantly relate to the provision for loan losses and the related allowance, determination of impaired 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 other real estate owned, prepayment rates, valuation of share-based compensation, the assessment that a liability should be recognized with respect to any matters under litigation, the calculation of current and deferred income taxes and the actuarial projections related to pension expense and the related liability. Cash Flows For purposes of reporting cash flows, cash and cash equivalents include cash and due from banks, federal funds sold and interest-bearing deposits with banks (items with stated original maturity of three months or less). 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 debt 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 security 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 date. 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. 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 and 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 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. The FASB issued Update 2017-1, 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 concentrated 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) require that to be considered a business, as 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 missing 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 outputs 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 is effective for public business entities for annual periods beginning after December 15, 2017, including interim periods within those periods. 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 No. 2016-15, Statement of Cash Flow (Topic 230): Classification 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 public 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 all of the amendments in the same period. 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 No. 2016-13, Current Expected Credit Losses (CECL), 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 model 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 will 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 off-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 required 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 beginning 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 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. 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net), in March 2016. This guidance is intended to clarify a potential implementation issue with respect to determining whether an entity is a principal or an agent in an arrangement. The guidance provides indicators to assist in this evaluation when another party is involved in the arrangement to identify which party is the principal and which party is the agent. The effective date for this guidance is the same as the effective date of Update 2014-09, Revenue from Contracts with Customers. 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 No. 2016-02, Leases, 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 balance 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 current real estate-specific provision and changes the guidance on sale-leaseback transactions, initial direct costs and lease executory costs. With respect to lessors, the guidance modifies the classification criteria and the accounting for sales-type and direct financing leases. 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 uncertainty 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 approach for leases that exist or are entered into after the beginning of the earliest comparative period in the financial statements. 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. 2016-01, Financial Instruments - Overall, 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 measurement 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 measured 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 available-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 public entities, the guidance in this update is effective for the first interim or annual period beginning after December 15, 2017. Early adoption by public entities is permitted as of the beginning of the year of adoption for selected amendments by a cumulative effect adjustment to the balance sheet. 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 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 recognition of gains and losses on the sale of certain nonfinancial assets, such as property and equipment, including real estate. This standard may affect an entity’s financial statements, business processes and internal control over financial reporting. The guidance is effective for the first interim or annual period beginning after December 15, 2017. The guidance must be adopted using either a full retrospective approach for all periods presented in the period of adoption or a modified retrospective approach. The Company’s revenue is comprised of net interest income and noninterest income. As ASU 2014-09 does not apply to revenue associated with financial instruments, net interest income, mortgage origination and servicing activities, and gains and losses from securities are not impacted by the standard. For other revenue streams such as: 1) wealth management income; 2) insurance agency commissions; 3) bank card fees; and 4) service charges on deposit accounts, we do not expect this standard to have a material impact on the timing of revenue recognition. We are currently evaluating the disclosure requirements of the standard. An assessment of the impact of this guidance has been performed and the Company does not expect it to have a material impact on the Company’s financial position, results of operations and cash flows.

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”). The Bank offers a broad range of commercial banking, retail banking, mortgage and trust services throughout central Maryland, Northern Virginia and the greater Washington D.C. market through its operation of 44 community offices and six financial centers across the region. The Bank also offers a comprehensive menu of insurance and wealth management services through its subsidiaries, Sandy Spring Insurance Corporation and West Financial Services, Inc.

Basis of Presentation

The accounting and reporting policies of the Company conform to accounting principles generally accepted in the United States of America (“GAAP”) and prevailing practices within the financial services industry for interim financial information and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and notes required for complete financial statements and prevailing practices within the banking industry. The following summary of significant accounting policies of the Company is presented to assist the reader in understanding the financial and other data presented in this report. Operating results for the three months ended March 31, 2017 are not necessarily indicative of the results that may be expected for any future periods or for the year ending December 31, 2017. In the opinion of management, all adjustments (comprising only normal recurring accruals) necessary for a fair presentation of the results of the interim periods have been included. Certain reclassifications have been made to prior period amounts, as necessary, to conform to the current period presentation. The Company has evaluated subsequent events through the date of the issuance of its financial statements.

These statements should be read in conjunction with the financial statements and accompanying notes included in the Company’s 2016 Annual Report on Form 10-K as filed with the Securities and Exchange Commission (“SEC”) on March 3, 2017. There have been no significant changes to the Company’s accounting policies as disclosed in the 2016 Annual Report on Form 10-K.

Principles of Consolidation

The unaudited condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiary, Sandy Spring Bank and its subsidiaries, Sandy Spring Insurance Corporation and West Financial Services, Inc. Consolidation has resulted in the elimination of all intercompany accounts and transactions.

Use of Estimates

The preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements, and affect the reported amounts of revenues earned and expenses incurred during the reporting period. Actual results could differ from those estimates. Estimates that could change significantly relate to the provision for loan losses and the related allowance, determination of impaired 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 other real estate owned, prepayment rates, valuation of share-based compensation, the assessment that a liability should be recognized with respect to any matters under litigation, the calculation of current and deferred income taxes and the actuarial projections related to pension expense and the related liability.

Cash Flows

For purposes of reporting cash flows, cash and cash equivalents include cash and due from banks, federal funds sold and interest-bearing deposits with banks (items with stated original maturity of three months or less).

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 debt 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 security 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 date. 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.

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 and 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 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.

The FASB issued Update 2017-1, 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 concentrated 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) require that to be considered a business, as 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 missing 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 outputs 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 is effective for public business entities for annual periods beginning after December 15, 2017, including interim periods within those periods. 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 No. 2016-15, Statement of Cash Flow (Topic 230): Classification 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 public 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 all of the amendments in the same period. 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 No. 2016-13, Current Expected Credit Losses (CECL), 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 model 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 will 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 off-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 required 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 beginning 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 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. 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net), in March 2016. This guidance is intended to clarify a potential implementation issue with respect to determining whether an entity is a principal or an agent in an arrangement. The guidance provides indicators to assist in this evaluation when another party is involved in the arrangement to identify which party is the principal and which party is the agent. The effective date for this guidance is the same as the effective date of Update 2014-09, Revenue from Contracts with Customers. 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 No. 2016-02, Leases, 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 balance 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 current real estate-specific provision and changes the guidance on sale-leaseback transactions, initial direct costs and lease executory costs. With respect to lessors, the guidance modifies the classification criteria and the accounting for sales-type and direct financing leases. 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 uncertainty 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 approach for leases that exist or are entered into after the beginning of the earliest comparative period in the financial statements. 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. 2016-01, Financial Instruments - Overall, 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 measurement 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 measured 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 available-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 public entities, the guidance in this update is effective for the first interim or annual period beginning after December 15, 2017. Early adoption by public entities is permitted as of the beginning of the year of adoption for selected amendments by a cumulative effect adjustment to the balance sheet. 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 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 recognition of gains and losses on the sale of certain nonfinancial assets, such as property and equipment, including real estate. This standard may affect an entity’s financial statements, business processes and internal control over financial reporting. The guidance is effective for the first interim or annual period beginning after December 15, 2017. The guidance must be adopted using either a full retrospective approach for all periods presented in the period of adoption or a modified retrospective approach. The Company’s revenue is comprised of net interest income and noninterest income. As ASU 2014-09 does not apply to revenue associated with financial instruments, net interest income, mortgage origination and servicing activities, and gains and losses from securities are not impacted by the standard. For other revenue streams such as: 1) wealth management income; 2) insurance agency commissions; 3) bank card fees; and 4) service charges on deposit accounts, we do not expect this standard to have a material impact on the timing of revenue recognition. We are currently evaluating the disclosure requirements of the standard. An assessment of the impact of this guidance has been performed and the Company does not expect it to have a material impact on the Company’s financial position, results of operations and cash flows.
