ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES [Abstract]
ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES	1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES Southern National Bancorp of Virginia, Inc. (“Southern National” or “SNBV” or the “Company”) is a corporation that was formed on July 28, 2004 under the laws of the Commonwealth of Virginia and is the holding company for Sonabank (“Sonabank” or the “Bank”) a Virginia state-chartered bank which commenced operations on April 14, 2005. As of the close of business on June 23, 2017, SNBV completed its merger with Eastern Virginia Bankshares, Inc. (“EVBS”) and the merger of EVBS’s wholly-owned subsidiary, EVB, with and into SNBV’s wholly-owned subsidiary, Sonabank. Sonabank provides a range of financial services to individuals and small and medium sized businesses. At December 31, 2019, Sonabank had forty-five full-service branches. Thirty-eight full-service retail branches are in Virginia, located in Ashland, Burgess, Callao, Central Garage, Charlottesville, Chester, Clifton Forge, Colonial Heights, Courtland, Deltaville, Fairfax, Front Royal, Gloucester, Gloucester Point, Hampton, Hartfield, Haymarket, Heathsville, Kilmarnock, Leesburg, McLean, Mechanicsville (2), Middleburg, Midlothian, New Market, Newport News, Quinton, Reston, Richmond, South Riding, Surry, Tappahannock (2), Urbanna, Warrenton, Waverly, and Williamsburg, and seven full-service retail branches in Maryland, located in Bethesda, Brandywine, Huntingtown, Owings, Rockville, Shady Grove, and Upper Marlboro. The accounting policies and practices of Southern National and its subsidiaries conform to U.S. generally accepted accounting principles (“U.S. GAAP”) and to general practice within the banking industry. Major policies and practices are described below: Principles of Consolidation The consolidated financial statements include the accounts of Southern National and its subsidiaries Sonabank and EVB Statutory Trust I (the “Trust”). Significant inter-company accounts and transactions have been eliminated in consolidation. Southern National consolidates subsidiaries in which it holds, directly or indirectly, more than 50 percent of the voting rights or where it exercises control. Entities where Southern National holds 20 to 50 percent of the voting rights, or has the ability to exercise significant influence, or both, are accounted for under the equity method. Southern National has an interest in one affiliate, Southern Trust Mortgage, LLC (“STM”), which it accounts for as an equity method investment. In addition, Southern National owns the Trust which is an unconsolidated subsidiary. The junior subordinated debt owed to the Trust is reported as a liability of Southern National. Use of Estimates The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from these estimates. Material estimates that are particularly susceptible to significant change in the near term include: the determination of the allowance for loan losses, the fair value of investment securities, other than temporary impairment of investment securities, the valuation of goodwill and intangible assets, other real estate owned (“OREO”) and deferred tax assets. Business Combinations U.S. GAAP requires that the acquisition method of accounting be used for all business combinations and that an acquirer be identified for each business combination. Under U.S. GAAP, the acquirer is the entity that obtains control of one or more businesses in the business combination, and the acquisition date is the date the acquirer achieves control. U.S. GAAP requires that the acquirer recognize the fair value of assets acquired, liabilities assumed, and any non-controlling interest in the acquiree at the acquisition date, with any excess of purchase price recognized as either intangibles or goodwill. If the initial accounting for a business combination is incomplete by the end of the reporting period in which the combination occurs, the acquirer shall report in its financial statements provisional amounts for the items for which the accounting is incomplete. The measurement period ends as soon as the acquirer receives the information it was seeking about facts and circumstances that existed as of the acquisition date or learns that more information is not obtainable. However, the measurement period shall not exceed one year from the acquisition date. The acquirer recognizes an increase (decrease) in the provisional amount recognized for an identifiable asset (liability) by means of a decrease (increase) in goodwill. Investment Securities Debt securities that Southern National has the positive intent and ability to hold to maturity are classified as held-to-maturity and carried at amortized cost. Securities classified as available for sale are those debt securities that may be sold in response to changes in interest rates, liquidity needs or other similar factors. Securities available for sale are carried at fair value, with unrealized gains or losses net of deferred taxes, included in accumulated other comprehensive income (loss) in stockholders’ equity. Premiums and discounts are generally amortized using the interest method with a constant effective yield without anticipating prepayments, except for mortgage-backed securities where prepayments are anticipated. Premiums on callable securities are amortized to their earliest call date. Prior to the adoption of Financial Accounting Standards Board (FASB) Accounting Standards Update (ASU) 2017-08 in 2019, premiums and discounts were recognized in interest income using the interest method over the terms of the securities without anticipating prepayments, except for mortgage-backed securities where prepayments were anticipated. Gains and losses on the sale of investment securities are recorded on the settlement date and are determined using the specific identification method. Southern National purchases amortizing investment securities in which the underlying assets are residential mortgage loans subject to prepayments. The actual principal reduction on these assets varies from the expected contractual principal reduction due to principal prepayments resulting from the borrowers’ election to refinance the underlying mortgage based on market and other conditions. The purchased premiums and discounts associated with these assets are amortized or accreted to interest income over the estimated life of the related assets. The estimated life is calculated by projecting future prepayments and the resulting principal cash flows until maturity. Prepayment rate projections utilize actual prepayment speed experience and available market information on like-kind instruments. The prepayment rates form the basis for income recognition of premiums and discounts on the related assets. Changes in prepayment estimates may cause the earnings recognized on these assets to vary over the term that the assets are held, creating volatility in the net interest margin. Prepayment rate assumptions are monitored and updated monthly to reflect actual activity and the most recent market projections. Management evaluates investment securities for other-than-temporary impairment (“OTTI”) on at least a quarterly basis, and more frequently when economic or market conditions warrant such an evaluation. For investment securities in an unrealized loss position, management considers the extent and duration of the unrealized loss, and the financial condition and near-term prospects of the issuer. Management also assesses whether it intends to sell, or it is more likely than not that it will be required to sell, an investment security in an unrealized loss position before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the entire difference between amortized cost and fair value is recognized as impairment through earnings. For debt securities that do not meet the aforementioned criteria, the amount of impairment is split into two components as follows: (1) OTTI related to credit loss, which must be recognized in the income statement and (2) OTTI related to other factors, which is recognized in other comprehensive income. The credit loss is defined as the difference between the present value of the cash flows expected to be collected and the amortized cost basis. For equity securities, the entire amount of impairment is recognized through earnings. In order to determine OTTI for purchased beneficial interests that, on the purchase date, were not highly rated, Southern National compares the present value of the remaining cash flows as estimated at the preceding evaluation date to the current expected remaining cash flows. OTTI is deemed to have occurred if there has been an adverse change in the remaining expected future cash flows. Loans Southern National provides mortgage, commercial and consumer loans to customers. A substantial portion of the loan portfolio is represented by loans secured by real estate throughout its market area. The ability of Southern National’s debtors to honor their contracts is in varying degrees dependent upon the real estate market conditions and general economic conditions in this area. Loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off are reported at their outstanding unpaid principal balances adjusted for the allowance for loan losses, purchased premiums and discounts and any deferred loan fees or costs on originated loans. Interest income is accrued on the unpaid principal balance. 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 without anticipating prepayments. Commercial real estate consists of borrowings secured by owner occupied and non-owner occupied commercial real estate. Repayment of these loans is dependent upon rental income or the subsequent sale of the property for loans secured by non-owner occupied commercial real estate and by cash flows from business operations for owner occupied commercial real estate. Loans for which the source of repayment is rental income are primarily impacted by local economic conditions which dictate occupancy rates and the amount of rent charged. Commercial real estate loans that are dependent on cash flows from operations can also be adversely affected by current market conditions for their product or service. Construction and land development primarily consist of borrowings to purchase and develop raw land into residential and non-residential properties. Construction loans are extended to individuals as well as corporations for the construction of an individual or multiple properties and are secured by raw land and the subsequent improvements. Repayment of the loans to real estate developers is dependent upon the sale or lease of properties to third parties in a timely fashion upon completion. Should there be delays in construction or a downturn in the market for those properties, there may be significant erosion in value which may be absorbed by Southern National. Commercial loans consist of borrowings for commercial purposes to individuals, corporations, partnerships, sole proprietorships, and other business enterprises. Commercial loans are generally secured by business assets such as equipment, accounts receivable, inventory, or any other asset excluding real estate and generally made to finance capital expenditures or operations. Southern National’s risk exposure is related to deterioration in the value of collateral securing the loan should foreclosure become necessary. Generally, business assets used or produced in operations do not maintain their value upon foreclosure which may require Southern National to write-down the value significantly to sell. Residential real estate loans consist of loans to individuals for the purchase of primary residences with repayment primarily through wage or other income sources of the individual borrower. Southern National’s loss exposure to these loans is dependent on local market conditions for residential properties as loan amounts are determined, in part, by the fair value of the property at origination. On May 15, 2014, we purchased a 44.0% equity investment and preferred stock of STM, a regional mortgage banking company headquartered in Virginia Beach, Virginia. On June 23, 2017, in connection with the EVBS acquisition, we added 4.9% of additional equity investment and preferred stock in STM, bringing us to a total equity investment of 48.9%. STM has mortgage banking originators in Delaware, Virginia, Maryland, North Carolina and South Carolina. STM only originates retail mortgage production. Sonabank has established with STM underwriting guidelines under which it will purchase residential construction only, construction loans that convert to permanent, and permanent loans primarily in its Virginia and Maryland footprint from STM. These will be largely loans that do not conform to FNMA or FHLMC standards because of size or acreage. Other consumer loans are comprised of loans to individuals both unsecured and secured and home equity loans secured by real estate (closed and open-end), with repayment dependent on individual wages and other income. The risk of loss on consumer loans is elevated as the collateral securing these loans, if any, rapidly depreciate in value or may be worthless and/or difficult to locate if repossession is necessary. Losses in this portfolio are generally relatively low, however, due to the small individual loan size and the balance outstanding as a percentage of Southern National’s entire portfolio. As part of the Greater Atlantic Bank (“GAB”) acquisition in 2009, the Bank and the Federal Deposit Insurance Corporation (“FDIC”) entered into a loss sharing agreement on approximately $143.4 million (cost basis) of GAB’s assets. The Bank shared in the losses on the loans and foreclosed loan collateral with the FDIC as specified in the loss sharing agreement; we refer to these assets collectively as “covered assets.” The indemnification against losses in the GAB commercial portfolio ended in December 2014. The FDIC indemnification on the GAB residential mortgages and the GAB HELOCs ended on December 31, 2019. Loans that were not covered in the loss sharing agreement with the FDIC are referred to as “non-covered loans.” The accrual of interest on all loans is discontinued at the time the loan is 90 days delinquent unless the credit is well secured and in process of collection. In all cases, loans are placed on nonaccrual status or charged-off at an earlier date if collection of principal and interest is considered doubtful. All interest accrued but not collected for loans that are placed on nonaccrual status or charged-off is reversed against interest income. The interest on these loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual status. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. Most of Southern National’s business activity is with customers located within Virginia and Maryland. Therefore, our exposure to credit risk is significantly affected by changes in the economy in those areas. We are not dependent on any single customer or group of customers whose insolvency would have a material adverse effect on operations. Southern National has purchased, primarily through acquisitions, individual loans and groups of loans, some of which have shown evidence of credit deterioration since origination. These purchased loans are recorded at fair value such that there is no carryover of the seller’s allowance for loan losses. After acquisition, losses are recognized by an increase in the allowance for loan losses. Purchased credit-impaired (“PCI”) loans are accounted for using the expected cash flow methodology, and purchased performing loans are accounted for using the contractual cash flow methodology. Such PCI loans are accounted for individually or aggregated into pools of loans based on common risk characteristics such as, credit score, loan type, and date of origination. Southern National estimates the amount and timing of expected cash flows for each PCI loan or pool, and the expected cash flows in excess of fair value are recorded as interest income over the remaining life of the loan or pool (accretable yield). The excess of the loans’ or pool’s contractual principal and interest over expected cash flows is not recorded (nonaccretable difference). Over the life of the loan or pool, expected cash flows continue to be estimated. If the present value of expected cash flows is less than the carrying amount, a loss is recorded. In accordance with FASB Accounting Standards Codification (“ASC”) 310-30, “Loans and debt securities acquired with Deteriorated Credit Quality,” and based on current information and events, if it becomes probable that there is a significant increase in cash flows previously expected to be collected or if actual cash flows are significantly greater than cash flows previously expected, the Bank will recalculate the amount of accretable yield for the acquired loans as the excess of the revised cash flows expected to be collected over the sum of (1) the initial investment in the loans less (2) cash collected less (3) write downs, if any plus (4) the amount of yield accreted to date. The amount of accretable yield will be adjusted by reclassification from non-accretable yield. This adjustment would be accounted for as a change in estimate with the amount of periodic accretion adjusted over the remaining life of the loans. Allowance for Loan and Lease Losses (“ALLL”) The allowance for loan and lease losses is a valuation allowance for probable incurred credit losses. Loan losses are charged against the allowance when management believes the collection of the principal is unlikely. Recoveries of amounts previously charged-off are credited to the allowance. Management’s determination of the adequacy of the allowance is based on a three year historical average net loss experience for each portfolio segment adjusted for current industry and economic conditions and estimates of their effect on loan collectability. While management uses available information to estimate losses on loans, future additions to the allowance may be necessary based on changes in economic conditions, particularly those affecting real estate values. The allowance consists of specific and general components. The specific component relates to loans that are individually classified as impaired. The general component provides for estimated losses in unimpaired loans and is based on historical loss experience adjusted for current factors. A loan is considered impaired when, based on current information and events, it is probable that Southern National will be unable to collect the scheduled payments of principal or interest when due according to the terms of the loan. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. Impairment is measured on a loan by loan basis by either the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price, or the fair value of the collateral if the loan is collateral dependent. The general component covers non-impaired loans and is based on historical loss experience adjusted for current factors. The historical loss experience is determined by portfolio segment and is based on the actual net loss history experienced by Southern National over the most recent three years, except consumer loans that are tracked on a two year basis. This actual loss experience is supplemented with other economic factors based on the risks present for each portfolio segment. These economic factors include consideration of the following: levels of and trends in delinquencies and impaired loans; levels of and trends in charge-offs and recoveries; trends in volume and terms of loans; effects of any changes in risk selection and underwriting standards; other changes in lending policies, procedures, and practices; experience, ability, and depth of lending management and other relevant staff; national and local economic trends and conditions; industry conditions; and effects of changes in credit concentrations. The following portfolio segments have been identified: owner occupied commercial real estate, non-owner occupied commercial real estate, construction and land development, commercial loans, 1-4 family residential, and other consumer. While underwriting practices in this environment are more stringent, the Bank estimates the effect of internal factors on future net loss experience to be fairly small. Management’s estimate of the effect of current external economic environmental conditions on future net loss experience is significant in all loan segments and particularly on loans secured by real estate including single family 1-4, non-owner occupied commercial real estate and construction and land development loans. These factors include excess inventory, generally less demand driven in part by fewer qualified borrowers and buyers. These considerations have played a significant role in management’s estimate of the adequacy of the allowance for loan and lease losses. Transfers of Financial Assets Transfers of financial assets are accounted for as sales, when control over the assets has been relinquished. Control over transferred assets is deemed to be surrendered when the assets have been isolated from Southern National, the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and Southern National does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity. Investments in Mortgage Affiliate Southern National’s investment in STM’s common stock is being accounted for under the equity method. Under the equity method, the carrying value of Southern National’s investment in STM was originally recorded at cost but is adjusted periodically to record Southern National’s proportionate share of STM’s earnings or losses through noninterest income and decreased by the amount of cash dividends or similar distributions received from STM. Southern National’s investment in STM’s preferred stock is considered to be a non-marketable equity security that does not have a readily determinable fair value. Equity securities with no recurring market value data available are reviewed periodically and any observable market value change are adjusting through net income. Southern National evaluated this non-marketable equity security for impairment and recoverability of the recorded investment by considering positive and negative evidence, including the profitability and asset quality of STM, dividend payment history and recent redemption experience. Impairment is assessed at each reporting period and if identified, is recognized in noninterest income. Bank Premises and Equipment Land is carried at cost. Premises and equipment are stated at cost less accumulated depreciation. Buildings and related components are depreciated using the straight-line method with useful lives of 30 years. Furniture, fixtures and equipment are depreciated using the straight-line method with useful lives ranging from 3 to 10 years. Operating Leases The Company leases certain properties and equipment under operating leases. The Company recognizes a liability to make lease payments, the operating lease liability, and an asset representing the right to use the underlying asset during the lease term, the right-of-use asset. In recognizing lease right-of-use assets and related right-of-use liabilities, we account for lease and non-lease components (such as taxes, insurance, and common area maintenance costs) separately as such amounts are generally readily determinable under our lease contracts. The operating lease liability is measured at the present value of the remaining lease payments, discounted at the Company’s incremental borrowing rate at inception. The right-of-use asset is measured at the amount of the operating lease liability adjusted for the remaining balance of any lease incentives received, any cumulative prepaid or accrued rent if the lease payments are uneven throughout the lease term, any unamortized initial direct costs, and any impairment of the right-of-use-asset. Lease expense consists of a single lease cost calculated so that the remaining cost of the lease is allocated over the remaining lease term on a straight-line basis, variable lease payments not included in the operating lease liability, and any impairment of the right-of-use asset. Lease renewal options are generally not included in the calculation of the operating lease liabilities, unless they are not reasonably certain to be exercised. The Company does not recognize short-term leases on the balance sheet. Goodwill and Intangible Assets Goodwill resulting from business combinations after January 1, 2009, is generally determined as the excess of the fair value of the consideration transferred, plus the fair value of any noncontrolling interests in the acquiree, over the fair value of the net assets acquired and liabilities assumed as of the acquisition date. Goodwill and intangible assets acquired in a purchase business combination and determined to have an indefinite useful life are not amortized, but tested for impairment at least annually. Southern National has selected September 30^th as the date to perform the annual goodwill impairment assessment. Intangible assets with definite useful lives are amortized over their estimated useful lives to their estimated residual values. Goodwill is the only intangible asset with an indefinite life on our balance sheet. Other intangible assets consist of loan servicing rights and core deposit intangible assets arising from whole-bank and branch acquisitions and are amortized over their estimated useful lives, which range from 6 to 15 years. Stock Based Compensation Compensation cost is recognized for stock options issued to employees, based on the fair value of these awards at the date of grant. A Black-Scholes option-pricing model is utilized to estimate the fair value of stock options. Compensation cost for grants of restricted shares is accounted for based on the closing price of Southern National’s common stock on the date the restricted shares are awarded. Compensation cost for stock options and restricted shares is recognized over the required service period, generally defined as the vesting period. For awards with graded vesting, compensation cost is recognized on a straight-line basis over the requisite service period for the entire award. Bank-owned Life Insurance Southern National has purchased, and acquired through acquisitions, life insurance policies on certain former and current key executives. Bank-owned life insurance is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement. Other Real Estate Owned (“OREO”) Real estate acquired through or instead of foreclosure is held for sale and initially recorded at fair value less costs to sell when acquired, establishing a new cost basis. If fair value declines subsequent to foreclosure, a direct charge-off is recorded through expense. Operating costs after acquisition are expensed as incurred. Stock in Federal Home Loan Bank (“FHLB”) and Federal Reserve Bank (“FRB”) The Bank is a member of the FHLB system. Members are required to own a certain amount of stock based on the level of borrowings and other factors, and may invest in additional amounts. The Bank is also required to own FRB stock with a par value equal to 6% of capital. FHLB and FRB stock are carried at cost, classified as a restricted security, and periodically evaluated for impairment based on ultimate recovery of par value. Both cash and stock dividends are reported as income. Impairment of Long-Lived Assets Premises and equipment, core deposit intangible assets and other long-term assets are reviewed for impairment when events indicate their carrying amount may not be recoverable from future undiscounted cash flows. If impaired, the assets are recorded at fair value. FDIC Indemnification Asset The acquisition of GAB on December 4, 2009 was accounted for under the acquisition method of accounting, and the assets and liabilities were recorded at their estimated fair values. The FDIC indemnification asset was measured separately from each of the covered asset categories as it was not contractually embedded in any of the covered asset categories. The indemnification asset represents the present value of cash flows expected to be received from the FDIC for future losses on covered assets based on the expected credit losses estimated for each covered loan or loan pool and the loss sharing percentages at the acquisition date. We acquired the GAB loans in December 2009 and continuously evaluated our estimates of expected losses on these loans. There were two agreements with the FDIC, one for single family assets which was a 10-year agreement which expired on December 31, 2019, and one for non-single family (commercial) assets which was a 5-year agreement which expired in December 2014. Retirement Plans Employee 401(k) plan expense is the amount of matching contributions. Supplemental retirement plan expense allocates the benefits over years of service. Loss Contingencies Loss contingencies, including claims and legal actions arising in the ordinary course of business, are recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated. Management does not believe there are such matters that will have a material effect on the financial statements. Dividend Restriction Banking regulations require maintaining certain capital levels and may limit the dividends paid by the Bank to Southern National or by Southern National to shareholders. Estimates and Uncertainties Estimates including the carrying value of investment securities, other than temporary impairment of investment securities, the determination of the allowance for loan losses and the valuation of goodwill and intangible assets involves uncertainties and matters of significant judgement regarding interest rates, credit risk, repayments and prepayments, and other factors, especially in the absence of broad markets for particular items. Changes in assumptions or in market conditions could significantly affect the estimates. Operating Segments While the chief decision-makers monitor the revenue streams of the various products and services, operations are managed and financial performance is evaluated on a company-wide basis. Discrete financial information is not available other than on a company-wide basis. Accordingly, all of the financial service operations are considered by management to be aggregated in one reportable operating segment. Reclassifications In certain instances, amounts reported in prior years’ consolidated financial statements have been reclassified to conform to the current financial statement presentation. Such reclassifications had no effect on previously reported cash flows, stockholders’ equity or net income. During 2019, the Company determined that certain assets were incorrectly recorded in the Company’s fixed asset accounting software in a prior period. In correcting these errors the Company has reduced the previously disclosed cost basis of bank premises and equipment and accumulated depreciation by $22.5 million each. These corrections did not result in a change to amounts previously reported as bank premises and equipment, net, stockholders’ equity, or net income. The Company has evaluated the effect of the error, both qualitatively and quantitatively, and concluded that it was immaterial. Advertising Costs Advertising costs are expensed as incurred. Income Taxes Income tax expense is the total of the current year income tax due or refundable and the change in deferred tax assets and liabilities. Deferred tax assets and liabilities are the expected future tax amounts for the temporary differences between carrying amounts and tax bases of assets and liabilities, computed using enacted tax rates. A valuation allowance, if needed, reduces deferred tax assets to the amount expected to be realized. A tax position is recognized as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50% likely of being realized on examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded. We have no unrecognized tax benefits and do not anticipate any increase in unrecognized tax benefits during the next twelve months. Should the accrual of any interest or penalties relative to unrecognized tax benefits be necessary, it is our policy to record such accruals in our income tax accounts; no such accruals exist as of December 31, 2019. Southern National and its subsidiaries file a consolidated U.S. federal tax return; Sonabank files a Maryland state income tax return and Southern National files a franchise tax return. These returns are subject to examination by taxing authorities for all years after 2015. On December 22, 2017 the Tax Cuts and Jobs Act was enacted. The law established a new flat corporate federal statutory income tax rate of 21%. For more information on the impact the new law had on Southern National, see discussion in Note 12 - Income Taxes. Restrictions on Cash No regulatory reserve or clearing requirements with the FRB were needed at December 31, 2019 and 2018. Consolidated Statements of Cash Flows For purposes of reporting cash flows, Southern National defines cash and cash equivalents as cash due from financial institutions, interest-bearing deposits and federal funds sold in other financial institutions with maturities less than 90 days. Net cash flows are reported for customer loan and deposit transactions and short-term borrowings. Earnings Per Share (“EPS”) Basic EPS is computed by dividing net income by the weighted average number of common shares outstanding during the year. Diluted EPS reflects additional common shares that would have been outstanding if dilutive potential common shares had been issued, as well as any adjustment to net income that would result from the assumed issuance. Potential common shares that may be issued by Southern National relate solely to outstanding stock options and warrants and are determined using the treasury stock method. Comprehensive Income Comprehensive income consists of net income and other comprehensive (loss) income. Other comprehensive (loss) income includes unrealized gains and losses on investment securities available for sale and the non-credit component of other than temporary impairment of investment securities held-to-maturity which are also recognized as a separate component of equity. Off Balance Sheet Credit Related Financial Instruments In the ordinary course of business, Southern National has entered into commitments to extend credit, standby letters of credit, and guarantees of previously sold credit card accounts assumed in the merger with EVBS. The face amount for these items represents the exposure to loss, before considering customer collateral or ability to repay. Fair Value Measurements In general, fair values of financial instruments are based upon quoted market prices, where available. If such quoted market prices are not available, fair value is based upon observable market-based parameters. Valuation assumptions may be made to ensure that financial instruments are recorded at fair value. These assumptions may reflect assumptions that market participants would use in pricing an asset or liability, among other things, as well as unobservable parameters. Any such valuation assumptions are applied consistently over time. Recent Accounting Pronouncements New Accounting Standards Adopted: In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). The FASB issued this ASU to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet by lessees for those leases classified as operating leases under current U.S. GAAP and disclosing key information about leasing arrangements. In July 2018, the FASB issued ASU 2018-10, Codification Improvements to Topic 842, Leases, which updated narrow aspects of the guidance issued in ASU 2016-02. The amendments in this ASU were effective for public business entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2018. Early adoption of this ASU was permitted for all entities. The Company adopted ASU 2016-02 and its subsequent updates in the first quarter of 2019 and inventoried and categorized its lease agreements. Upon adoption, the Company recognized right-of-use assets and associated operating lease liabilities of $8.6 million and $9.1 million, respectively. Right-of-use assets and operating lease liabilities are reflected on our consolidated balance sheets. The Company elected to apply certain practical adoption expedients provided under the updates whereby we did not reassess (i) whether any expired or existing contracts are or contain leases, (ii) the lease classification for any expired or existing leases and (iii) initial direct costs for existing leases. The Company has elected to use the practical expedient to make an accounting policy election for property leases to use the discount rates in effect on January 2, 2019 for the remaining life of the leases. The Company currently does not have any finance leases. See Note 6 – Leases for additional disclosures related to leases. In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment, which eliminates the second step of the previous FASB guidance for testing goodwill for impairment and is intended to reduce cost and complexity of goodwill impairment testing. The amendments in this ASU modify the concept of impairment from the condition that exists when the carrying amount of goodwill exceeds its implied fair value to the condition that exists when the carrying amount of a reporting unit exceeds its fair value. After determining if the carrying amount of a reporting unit exceeds its fair value, the entity should take an impairment charge of the same amount to the goodwill for that reporting unit, not to exceed the total goodwill amount for that reporting unit. ASU 2017-04 is effective for annual periods beginning after December 15, 2019, including interim periods within those annual periods. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company early adopted ASU 2017-04 in the third quarter of 2019 and it did not have an impact on the Company’s consolidated financial statements. In March 2017, the FASB issued ASU 2017-08, Receivables – Nonrefundable Fees and Other Costs (Subtopic 310-20), Premium Amortization on Purchased Callable Debt Securities, which shortens the amortization period for certain callable debt securities held at a premium. Specifically, the amendments require the premium to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. ASU 2017-08 became effective for public entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The Company adopted ASU 2017-08 in the first quarter of 2019 and it did not have a material impact on the Company’s consolidated financial statements. New Accounting Standards Not Yet Adopted: In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which along with several other subsequent codification updates related to accounting for credit losses, sets forth a “current expected credit loss” ("CECL") model requiring the Company to measure all expected credit losses for financial instruments recorded at amortized cost held at the reporting date. The estimate is to be based on historical experience, current conditions and reasonable and supportable forecasts. This replaces the existing incurred loss model and is applicable to the measurement of credit losses on financial assets measured at amortized cost and applies to some off-balance sheet credit exposures. The amendments are effective for the Company beginning January 1, 2020. Southern National engaged a third-party to collect data that was needed to produce historical inputs into any models created as a result of adopting this ASU. We have had our models validated and are currently evaluating the results and certain changes to our models. We currently expect the adoption of this ASU will result in an increase of approximately $10.0 million to $15.0 million in our allowance for loan losses, including transfers of non-accretable discount on purchased credit-impaired loans. As we are currently finalizing the execution of our implementation controls and processes, the ultimate impact of the adoption of this ASU could materially differ from our current expectation. The expected increase is a result of changing from an “incurred loss” model, which encompasses allowances for current known and inherent losses within the portfolio, to an “expected loss” model, which encompasses allowances for losses expected to be incurred over the life of the portfolio. The adoption of this ASU requires that we establish an allowance for expected credit losses for certain debt securities and other financial assets; however, we do not expect these allowances to be material. We plan to elect the federal banking agencies’ rule providing for an optional three-year phase-in period for the day-one adverse regulatory capital effects upon adopting the standard. The adoption of this ASU is not expected to have a significant impact on our regulatory capital ratios. In August 2018, FASB issued ASU 2018-13, Fair Value measurement (Topic 820). This ASU adds, eliminates and modifies certain disclosure requirements for fair value measurements. The amendments in ASU 2018-13 are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted. The disclosures are effective using the prospective method for certain disclosures and retrospective for a majority of the disclosures. Southern National is currently in the process of evaluating the impact of adopting the new guidance on its consolidated financial statements and disclosures. In December 2019, FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes (Topic 740). This ASU simplifies the accounting for income taxes by eliminating certain exceptions to the guidance in ASC 740 related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the recognition for deferred tax liabilities for outside basis differences. This ASU also simplifies aspects of the accounting for franchise taxes and enacted changes in tax laws or rates and clarifies the accounting transactions that result in a step-up in the tax basis of goodwill. ASU 2019-12 is effective for annual periods beginning after December 15, 2020, including interim periods within those annual periods. Early adoption is permitted. Southern National is currently in the process of evaluating the impact of adopting the new guidance on its consolidated financial statements and disclosures.

ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES [Abstract]

ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

Southern National Bancorp of Virginia, Inc. (“Southern National” or “SNBV” or the “Company”) is a corporation that was formed on July 28, 2004 under the laws of the Commonwealth of Virginia and is the holding company for Sonabank (“Sonabank” or the “Bank”) a Virginia state-chartered bank which commenced operations on April 14, 2005. As of the close of business on June 23, 2017, SNBV completed its merger with Eastern Virginia Bankshares, Inc. (“EVBS”) and the merger of EVBS’s wholly-owned subsidiary, EVB, with and into SNBV’s wholly-owned subsidiary, Sonabank.

Sonabank provides a range of financial services to individuals and small and medium sized businesses. At December 31, 2019, Sonabank had forty-five full-service branches. Thirty-eight full-service retail branches are in Virginia, located in Ashland, Burgess, Callao, Central Garage, Charlottesville, Chester, Clifton Forge, Colonial Heights, Courtland, Deltaville, Fairfax, Front Royal, Gloucester, Gloucester Point, Hampton, Hartfield, Haymarket, Heathsville, Kilmarnock, Leesburg, McLean, Mechanicsville (2), Middleburg, Midlothian, New Market, Newport News, Quinton, Reston, Richmond, South Riding, Surry, Tappahannock (2), Urbanna, Warrenton, Waverly, and Williamsburg, and seven full-service retail branches in Maryland, located in Bethesda, Brandywine, Huntingtown, Owings, Rockville, Shady Grove, and Upper Marlboro.

The accounting policies and practices of Southern National and its subsidiaries conform to U.S. generally accepted accounting principles (“U.S. GAAP”) and to general practice within the banking industry. Major policies and practices are described below:

Principles of Consolidation

The consolidated financial statements include the accounts of Southern National and its subsidiaries Sonabank and EVB Statutory Trust I (the “Trust”). Significant inter-company accounts and transactions have been eliminated in consolidation. Southern National consolidates subsidiaries in which it holds, directly or indirectly, more than 50 percent of the voting rights or where it exercises control. Entities where Southern National holds 20 to 50 percent of the voting rights, or has the ability to exercise significant influence, or both, are accounted for under the equity method. Southern National has an interest in one affiliate, Southern Trust Mortgage, LLC (“STM”), which it accounts for as an equity method investment. In addition, Southern National owns the Trust which is an unconsolidated subsidiary. The junior subordinated debt owed to the Trust is reported as a liability of Southern National.

Use of Estimates

The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from these estimates. Material estimates that are particularly susceptible to significant change in the near term include: the determination of the allowance for loan losses, the fair value of investment securities, other than temporary impairment of investment securities, the valuation of goodwill and intangible assets, other real estate owned (“OREO”) and deferred tax assets.

Business Combinations

U.S. GAAP requires that the acquisition method of accounting be used for all business combinations and that an acquirer be identified for each business combination. Under U.S. GAAP, the acquirer is the entity that obtains control of one or more businesses in the business combination, and the acquisition date is the date the acquirer achieves control. U.S. GAAP requires that the acquirer recognize the fair value of assets acquired, liabilities assumed, and any non-controlling interest in the acquiree at the acquisition date, with any excess of purchase price recognized as either intangibles or goodwill.

If the initial accounting for a business combination is incomplete by the end of the reporting period in which the combination occurs, the acquirer shall report in its financial statements provisional amounts for the items for which the accounting is incomplete. The measurement period ends as soon as the acquirer receives the information it was seeking

about facts and circumstances that existed as of the acquisition date or learns that more information is not obtainable. However, the measurement period shall not exceed one year from the acquisition date. The acquirer recognizes an increase (decrease) in the provisional amount recognized for an identifiable asset (liability) by means of a decrease (increase) in goodwill.

Investment Securities

Debt securities that Southern National has the positive intent and ability to hold to maturity are classified as held-to-maturity and carried at amortized cost.

Securities classified as available for sale are those debt securities that may be sold in response to changes in interest rates, liquidity needs or other similar factors. Securities available for sale are carried at fair value, with unrealized gains or losses net of deferred taxes, included in accumulated other comprehensive income (loss) in stockholders’ equity.

Premiums and discounts are generally amortized using the interest method with a constant effective yield without anticipating prepayments, except for mortgage-backed securities where prepayments are anticipated. Premiums on callable securities are amortized to their earliest call date. Prior to the adoption of Financial Accounting Standards Board (FASB) Accounting Standards Update (ASU) 2017-08 in 2019, premiums and discounts were recognized in interest income using the interest method over the terms of the securities without anticipating prepayments, except for mortgage-backed securities where prepayments were anticipated. Gains and losses on the sale of investment securities are recorded on the settlement date and are determined using the specific identification method.

Southern National purchases amortizing investment securities in which the underlying assets are residential mortgage loans subject to prepayments. The actual principal reduction on these assets varies from the expected contractual principal reduction due to principal prepayments resulting from the borrowers’ election to refinance the underlying mortgage based on market and other conditions. The purchased premiums and discounts associated with these assets are amortized or accreted to interest income over the estimated life of the related assets. The estimated life is calculated by projecting future prepayments and the resulting principal cash flows until maturity. Prepayment rate projections utilize actual prepayment speed experience and available market information on like-kind instruments. The prepayment rates form the basis for income recognition of premiums and discounts on the related assets. Changes in prepayment estimates may cause the earnings recognized on these assets to vary over the term that the assets are held, creating volatility in the net interest margin. Prepayment rate assumptions are monitored and updated monthly to reflect actual activity and the most recent market projections.

Management evaluates investment securities for other-than-temporary impairment (“OTTI”) on at least a quarterly basis, and more frequently when economic or market conditions warrant such an evaluation. For investment securities in an unrealized loss position, management considers the extent and duration of the unrealized loss, and the financial condition and near-term prospects of the issuer. Management also assesses whether it intends to sell, or it is more likely than not that it will be required to sell, an investment security in an unrealized loss position before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the entire difference between amortized cost and fair value is recognized as impairment through earnings. For debt securities that do not meet the aforementioned criteria, the amount of impairment is split into two components as follows: (1) OTTI related to credit loss, which must be recognized in the income statement and (2) OTTI related to other factors, which is recognized in other comprehensive income. The credit loss is defined as the difference between the present value of the cash flows expected to be collected and the amortized cost basis. For equity securities, the entire amount of impairment is recognized through earnings.

In order to determine OTTI for purchased beneficial interests that, on the purchase date, were not highly rated, Southern National compares the present value of the remaining cash flows as estimated at the preceding evaluation date to the current expected remaining cash flows. OTTI is deemed to have occurred if there has been an adverse change in the remaining expected future cash flows.

Loans

Southern National provides mortgage, commercial and consumer loans to customers. A substantial portion of the loan portfolio is represented by loans secured by real estate throughout its market area. The ability of Southern National’s

debtors to honor their contracts is in varying degrees dependent upon the real estate market conditions and general economic conditions in this area.

Loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off are reported at their outstanding unpaid principal balances adjusted for the allowance for loan losses, purchased premiums and discounts and any deferred loan fees or costs on originated loans. Interest income is accrued on the unpaid principal balance. 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 without anticipating prepayments.

Commercial real estate consists of borrowings secured by owner occupied and non-owner occupied commercial real estate. Repayment of these loans is dependent upon rental income or the subsequent sale of the property for loans secured by non-owner occupied commercial real estate and by cash flows from business operations for owner occupied commercial real estate. Loans for which the source of repayment is rental income are primarily impacted by local economic conditions which dictate occupancy rates and the amount of rent charged. Commercial real estate loans that are dependent on cash flows from operations can also be adversely affected by current market conditions for their product or service.

Construction and land development primarily consist of borrowings to purchase and develop raw land into residential and non-residential properties. Construction loans are extended to individuals as well as corporations for the construction of an individual or multiple properties and are secured by raw land and the subsequent improvements. Repayment of the loans to real estate developers is dependent upon the sale or lease of properties to third parties in a timely fashion upon completion. Should there be delays in construction or a downturn in the market for those properties, there may be significant erosion in value which may be absorbed by Southern National.

Commercial loans consist of borrowings for commercial purposes to individuals, corporations, partnerships, sole proprietorships, and other business enterprises. Commercial loans are generally secured by business assets such as equipment, accounts receivable, inventory, or any other asset excluding real estate and generally made to finance capital expenditures or operations. Southern National’s risk exposure is related to deterioration in the value of collateral securing the loan should foreclosure become necessary. Generally, business assets used or produced in operations do not maintain their value upon foreclosure which may require Southern National to write-down the value significantly to sell.

Residential real estate loans consist of loans to individuals for the purchase of primary residences with repayment primarily through wage or other income sources of the individual borrower. Southern National’s loss exposure to these loans is dependent on local market conditions for residential properties as loan amounts are determined, in part, by the fair value of the property at origination.

On May 15, 2014, we purchased a 44.0% equity investment and preferred stock of STM, a regional mortgage banking company headquartered in Virginia Beach, Virginia. On June 23, 2017, in connection with the EVBS acquisition, we added 4.9% of additional equity investment and preferred stock in STM, bringing us to a total equity investment of 48.9%. STM has mortgage banking originators in Delaware, Virginia, Maryland, North Carolina and South Carolina. STM only originates retail mortgage production.

Sonabank has established with STM underwriting guidelines under which it will purchase residential construction only, construction loans that convert to permanent, and permanent loans primarily in its Virginia and Maryland footprint from STM. These will be largely loans that do not conform to FNMA or FHLMC standards because of size or acreage.

Other consumer loans are comprised of loans to individuals both unsecured and secured and home equity loans secured by real estate (closed and open-end), with repayment dependent on individual wages and other income. The risk of loss on consumer loans is elevated as the collateral securing these loans, if any, rapidly depreciate in value or may be worthless and/or difficult to locate if repossession is necessary. Losses in this portfolio are generally relatively low, however, due to the small individual loan size and the balance outstanding as a percentage of Southern National’s entire portfolio.

As part of the Greater Atlantic Bank (“GAB”) acquisition in 2009, the Bank and the Federal Deposit Insurance Corporation (“FDIC”) entered into a loss sharing agreement on approximately $143.4 million (cost basis) of GAB’s assets. The Bank shared in the losses on the loans and foreclosed loan collateral with the FDIC as specified in the loss sharing agreement; we refer to these assets collectively as “covered assets.” The indemnification against losses in the GAB commercial portfolio ended in December 2014. The FDIC indemnification on the GAB residential mortgages and the GAB HELOCs ended on December 31, 2019. Loans that were not covered in the loss sharing agreement with the FDIC are referred to as “non-covered loans.”

The accrual of interest on all loans is discontinued at the time the loan is 90 days delinquent unless the credit is well secured and in process of collection. In all cases, loans are placed on nonaccrual status or charged-off at an earlier date if collection of principal and interest is considered doubtful.

All interest accrued but not collected for loans that are placed on nonaccrual status or charged-off is reversed against interest income. The interest on these loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual status. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured.

Most of Southern National’s business activity is with customers located within Virginia and Maryland. Therefore, our exposure to credit risk is significantly affected by changes in the economy in those areas. We are not dependent on any single customer or group of customers whose insolvency would have a material adverse effect on operations.

Southern National has purchased, primarily through acquisitions, individual loans and groups of loans, some of which have shown evidence of credit deterioration since origination. These purchased loans are recorded at fair value such that there is no carryover of the seller’s allowance for loan losses. After acquisition, losses are recognized by an increase in the allowance for loan losses. Purchased credit-impaired (“PCI”) loans are accounted for using the expected cash flow methodology, and purchased performing loans are accounted for using the contractual cash flow methodology.

Such PCI loans are accounted for individually or aggregated into pools of loans based on common risk characteristics such as, credit score, loan type, and date of origination. Southern National estimates the amount and timing of expected cash flows for each PCI loan or pool, and the expected cash flows in excess of fair value are recorded as interest income over the remaining life of the loan or pool (accretable yield). The excess of the loans’ or pool’s contractual principal and interest over expected cash flows is not recorded (nonaccretable difference).

Over the life of the loan or pool, expected cash flows continue to be estimated. If the present value of expected cash flows is less than the carrying amount, a loss is recorded. In accordance with FASB Accounting Standards Codification (“ASC”) 310-30, “Loans and debt securities acquired with Deteriorated Credit Quality,” and based on current information and events, if it becomes probable that there is a significant increase in cash flows previously expected to be collected or if actual cash flows are significantly greater than cash flows previously expected, the Bank will recalculate the amount of accretable yield for the acquired loans as the excess of the revised cash flows expected to be collected over the sum of (1) the initial investment in the loans less (2) cash collected less (3) write downs, if any plus (4) the amount of yield accreted to date. The amount of accretable yield will be adjusted by reclassification from non-accretable yield. This adjustment would be accounted for as a change in estimate with the amount of periodic accretion adjusted over the remaining life of the loans.

Allowance for Loan and Lease Losses (“ALLL”)

The allowance for loan and lease losses is a valuation allowance for probable incurred credit losses. Loan losses are charged against the allowance when management believes the collection of the principal is unlikely. Recoveries of amounts previously charged-off are credited to the allowance. Management’s determination of the adequacy of the allowance is based on a three year historical average net loss experience for each portfolio segment adjusted for current industry and economic conditions and estimates of their effect on loan collectability. While management uses available information to estimate losses on loans, future additions to the allowance may be necessary based on changes in economic conditions, particularly those affecting real estate values.

The allowance consists of specific and general components. The specific component relates to loans that are individually classified as impaired. The general component provides for estimated losses in unimpaired loans and is based on historical loss experience adjusted for current factors.

A loan is considered impaired when, based on current information and events, it is probable that Southern National will be unable to collect the scheduled payments of principal or interest when due according to the terms of the loan. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. Impairment is measured on a loan by loan basis by either the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price, or the fair value of the collateral if the loan is collateral dependent.

The general component covers non-impaired loans and is based on historical loss experience adjusted for current factors. The historical loss experience is determined by portfolio segment and is based on the actual net loss history experienced by Southern National over the most recent three years, except consumer loans that are tracked on a two year basis. This actual loss experience is supplemented with other economic factors based on the risks present for each portfolio segment. These economic factors include consideration of the following: levels of and trends in delinquencies and impaired loans; levels of and trends in charge-offs and recoveries; trends in volume and terms of loans; effects of any changes in risk selection and underwriting standards; other changes in lending policies, procedures, and practices; experience, ability, and depth of lending management and other relevant staff; national and local economic trends and conditions; industry conditions; and effects of changes in credit concentrations. The following portfolio segments have been identified: owner occupied commercial real estate, non-owner occupied commercial real estate, construction and land development, commercial loans, 1-4 family residential, and other consumer. While underwriting practices in this environment are more stringent, the Bank estimates the effect of internal factors on future net loss experience to be fairly small. Management’s estimate of the effect of current external economic environmental conditions on future net loss experience is significant in all loan segments and particularly on loans secured by real estate including single family 1-4, non-owner occupied commercial real estate and construction and land development loans. These factors include excess inventory, generally less demand driven in part by fewer qualified borrowers and buyers. These considerations have played a significant role in management’s estimate of the adequacy of the allowance for loan and lease losses.

Transfers of Financial Assets

Transfers of financial assets are accounted for as sales, when control over the assets has been relinquished. Control over transferred assets is deemed to be surrendered when the assets have been isolated from Southern National, the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and Southern National does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity.

Investments in Mortgage Affiliate

Southern National’s investment in STM’s common stock is being accounted for under the equity method. Under the equity method, the carrying value of Southern National’s investment in STM was originally recorded at cost but is adjusted periodically to record Southern National’s proportionate share of STM’s earnings or losses through noninterest income and decreased by the amount of cash dividends or similar distributions received from STM.

Southern National’s investment in STM’s preferred stock is considered to be a non-marketable equity security that does not have a readily determinable fair value. Equity securities with no recurring market value data available are reviewed periodically and any observable market value change are adjusting through net income. Southern National evaluated this non-marketable equity security for impairment and recoverability of the recorded investment by considering positive and negative evidence, including the profitability and asset quality of STM, dividend payment history and recent redemption experience. Impairment is assessed at each reporting period and if identified, is recognized in noninterest income.

Bank Premises and Equipment

Land is carried at cost. Premises and equipment are stated at cost less accumulated depreciation. Buildings and related components are depreciated using the straight-line method with useful lives of 30 years. Furniture, fixtures and equipment are depreciated using the straight-line method with useful lives ranging from 3 to 10 years.

Operating Leases

The Company leases certain properties and equipment under operating leases. The Company recognizes a liability to make lease payments, the operating lease liability, and an asset representing the right to use the underlying asset during the lease term, the right-of-use asset. In recognizing lease right-of-use assets and related right-of-use liabilities, we account for lease and non-lease components (such as taxes, insurance, and common area maintenance costs) separately as such amounts are generally readily determinable under our lease contracts. The operating lease liability is measured at the present value of the remaining lease payments, discounted at the Company’s incremental borrowing rate at inception. The right-of-use asset is measured at the amount of the operating lease liability adjusted for the remaining balance of any lease incentives received, any cumulative prepaid or accrued rent if the lease payments are uneven throughout the lease term, any unamortized initial direct costs, and any impairment of the right-of-use-asset. Lease expense consists of a single lease cost calculated so that the remaining cost of the lease is allocated over the remaining lease term on a straight-line basis, variable lease payments not included in the operating lease liability, and any impairment of the right-of-use asset. Lease renewal options are generally not included in the calculation of the operating lease liabilities, unless they are not reasonably certain to be exercised. The Company does not recognize short-term leases on the balance sheet.

Goodwill and Intangible Assets

Goodwill resulting from business combinations after January 1, 2009, is generally determined as the excess of the fair value of the consideration transferred, plus the fair value of any noncontrolling interests in the acquiree, over the fair value of the net assets acquired and liabilities assumed as of the acquisition date. Goodwill and intangible assets acquired in a purchase business combination and determined to have an indefinite useful life are not amortized, but tested for impairment at least annually. Southern National has selected September 30^th as the date to perform the annual goodwill impairment assessment. Intangible assets with definite useful lives are amortized over their estimated useful lives to their estimated residual values. Goodwill is the only intangible asset with an indefinite life on our balance sheet.

Other intangible assets consist of loan servicing rights and core deposit intangible assets arising from whole-bank and branch acquisitions and are amortized over their estimated useful lives, which range from 6 to 15 years.

Stock Based Compensation

Compensation cost is recognized for stock options issued to employees, based on the fair value of these awards at the date of grant. A Black-Scholes option-pricing model is utilized to estimate the fair value of stock options. Compensation cost for grants of restricted shares is accounted for based on the closing price of Southern National’s common stock on the date the restricted shares are awarded. Compensation cost for stock options and restricted shares is recognized over the required service period, generally defined as the vesting period. For awards with graded vesting, compensation cost is recognized on a straight-line basis over the requisite service period for the entire award.

Bank-owned Life Insurance

Southern National has purchased, and acquired through acquisitions, life insurance policies on certain former and current key executives. Bank-owned life insurance is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement.

Other Real Estate Owned (“OREO”)

Real estate acquired through or instead of foreclosure is held for sale and initially recorded at fair value less costs to sell when acquired, establishing a new cost basis. If fair value declines subsequent to foreclosure, a direct charge-off is recorded through expense. Operating costs after acquisition are expensed as incurred.

Stock in Federal Home Loan Bank (“FHLB”) and Federal Reserve Bank (“FRB”)

The Bank is a member of the FHLB system. Members are required to own a certain amount of stock based on the level of borrowings and other factors, and may invest in additional amounts. The Bank is also required to own FRB stock with a par value equal to 6% of capital. FHLB and FRB stock are carried at cost, classified as a restricted security, and periodically evaluated for impairment based on ultimate recovery of par value. Both cash and stock dividends are reported as income.

Impairment of Long-Lived Assets

Premises and equipment, core deposit intangible assets and other long-term assets are reviewed for impairment when events indicate their carrying amount may not be recoverable from future undiscounted cash flows. If impaired, the assets are recorded at fair value.

FDIC Indemnification Asset

The acquisition of GAB on December 4, 2009 was accounted for under the acquisition method of accounting, and the assets and liabilities were recorded at their estimated fair values. The FDIC indemnification asset was measured separately from each of the covered asset categories as it was not contractually embedded in any of the covered asset categories. The indemnification asset represents the present value of cash flows expected to be received from the FDIC for future losses on covered assets based on the expected credit losses estimated for each covered loan or loan pool and the loss sharing percentages at the acquisition date. We acquired the GAB loans in December 2009 and continuously evaluated our estimates of expected losses on these loans. There were two agreements with the FDIC, one for single family assets which was a 10-year agreement which expired on December 31, 2019, and one for non-single family (commercial) assets which was a 5-year agreement which expired in December 2014.

Retirement Plans

Employee 401(k) plan expense is the amount of matching contributions. Supplemental retirement plan expense allocates the benefits over years of service.

Loss Contingencies

Loss contingencies, including claims and legal actions arising in the ordinary course of business, are recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated. Management does not believe there are such matters that will have a material effect on the financial statements.

Dividend Restriction

Banking regulations require maintaining certain capital levels and may limit the dividends paid by the Bank to Southern National or by Southern National to shareholders.

Estimates and Uncertainties

Estimates including the carrying value of investment securities, other than temporary impairment of investment securities, the determination of the allowance for loan losses and the valuation of goodwill and intangible assets involves uncertainties and matters of significant judgement regarding interest rates, credit risk, repayments and prepayments, and

other factors, especially in the absence of broad markets for particular items. Changes in assumptions or in market conditions could significantly affect the estimates.

Operating Segments

While the chief decision-makers monitor the revenue streams of the various products and services, operations are managed and financial performance is evaluated on a company-wide basis. Discrete financial information is not available other than on a company-wide basis. Accordingly, all of the financial service operations are considered by management to be aggregated in one reportable operating segment.

Reclassifications

In certain instances, amounts reported in prior years’ consolidated financial statements have been reclassified to conform to the current financial statement presentation. Such reclassifications had no effect on previously reported cash flows, stockholders’ equity or net income.

During 2019, the Company determined that certain assets were incorrectly recorded in the Company’s fixed asset accounting software in a prior period. In correcting these errors the Company has reduced the previously disclosed cost basis of bank premises and equipment and accumulated depreciation by $22.5 million each. These corrections did not result in a change to amounts previously reported as bank premises and equipment, net, stockholders’ equity, or net income. The Company has evaluated the effect of the error, both qualitatively and quantitatively, and concluded that it was immaterial.

Advertising Costs

Advertising costs are expensed as incurred.

Income Taxes

Income tax expense is the total of the current year income tax due or refundable and the change in deferred tax assets and liabilities. Deferred tax assets and liabilities are the expected future tax amounts for the temporary differences between carrying amounts and tax bases of assets and liabilities, computed using enacted tax rates. A valuation allowance, if needed, reduces deferred tax assets to the amount expected to be realized.

A tax position is recognized as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50% likely of being realized on examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded. We have no unrecognized tax benefits and do not anticipate any increase in unrecognized tax benefits during the next twelve months. Should the accrual of any interest or penalties relative to unrecognized tax benefits be necessary, it is our policy to record such accruals in our income tax accounts; no such accruals exist as of December 31, 2019. Southern National and its subsidiaries file a consolidated U.S. federal tax return; Sonabank files a Maryland state income tax return and Southern National files a franchise tax return. These returns are subject to examination by taxing authorities for all years after 2015.

On December 22, 2017 the Tax Cuts and Jobs Act was enacted. The law established a new flat corporate federal statutory income tax rate of 21%. For more information on the impact the new law had on Southern National, see discussion in Note 12 - Income Taxes.

Restrictions on Cash

No regulatory reserve or clearing requirements with the FRB were needed at December 31, 2019 and 2018.

Consolidated Statements of Cash Flows

For purposes of reporting cash flows, Southern National defines cash and cash equivalents as cash due from financial institutions, interest-bearing deposits and federal funds sold in other financial institutions with maturities less than 90 days. Net cash flows are reported for customer loan and deposit transactions and short-term borrowings.

Earnings Per Share (“EPS”)

Basic EPS is computed by dividing net income by the weighted average number of common shares outstanding during the year. Diluted EPS reflects additional common shares that would have been outstanding if dilutive potential common shares had been issued, as well as any adjustment to net income that would result from the assumed issuance. Potential common shares that may be issued by Southern National relate solely to outstanding stock options and warrants and are determined using the treasury stock method.

Comprehensive Income

Comprehensive income consists of net income and other comprehensive (loss) income. Other comprehensive (loss) income includes unrealized gains and losses on investment securities available for sale and the non-credit component of other than temporary impairment of investment securities held-to-maturity which are also recognized as a separate component of equity.

Off Balance Sheet Credit Related Financial Instruments

In the ordinary course of business, Southern National has entered into commitments to extend credit, standby letters of credit, and guarantees of previously sold credit card accounts assumed in the merger with EVBS. The face amount for these items represents the exposure to loss, before considering customer collateral or ability to repay.

Fair Value Measurements

In general, fair values of financial instruments are based upon quoted market prices, where available. If such quoted market prices are not available, fair value is based upon observable market-based parameters. Valuation assumptions may be made to ensure that financial instruments are recorded at fair value. These assumptions may reflect assumptions that market participants would use in pricing an asset or liability, among other things, as well as unobservable parameters. Any such valuation assumptions are applied consistently over time.

Recent Accounting Pronouncements

New Accounting Standards Adopted:

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). The FASB issued this ASU to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet by lessees for those leases classified as operating leases under current U.S. GAAP and disclosing key information about leasing arrangements. In July 2018, the FASB issued ASU 2018-10, Codification Improvements to Topic 842, Leases, which updated narrow aspects of the guidance issued in ASU 2016-02. The amendments in this ASU were effective for public business entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2018. Early adoption of this ASU was permitted for all entities. The Company adopted ASU 2016-02 and its subsequent updates in the first quarter of 2019 and inventoried and categorized its lease agreements. Upon adoption, the Company recognized right-of-use assets and associated operating lease liabilities of $8.6 million and $9.1 million, respectively. Right-of-use assets and operating lease liabilities are reflected on our consolidated balance sheets. The Company elected to apply certain practical adoption expedients provided under the updates whereby we did not reassess (i) whether any expired or existing contracts are or contain leases, (ii) the lease classification for any expired or existing leases and (iii) initial direct costs for existing leases. The Company has elected to use the practical expedient to make an accounting policy election for property leases to use the discount rates in effect on January 2, 2019 for the remaining life

of the leases. The Company currently does not have any finance leases. See Note 6 – Leases for additional disclosures related to leases.

In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment, which eliminates the second step of the previous FASB guidance for testing goodwill for impairment and is intended to reduce cost and complexity of goodwill impairment testing. The amendments in this ASU modify the concept of impairment from the condition that exists when the carrying amount of goodwill exceeds its implied fair value to the condition that exists when the carrying amount of a reporting unit exceeds its fair value. After determining if the carrying amount of a reporting unit exceeds its fair value, the entity should take an impairment charge of the same amount to the goodwill for that reporting unit, not to exceed the total goodwill amount for that reporting unit. ASU 2017-04 is effective for annual periods beginning after December 15, 2019, including interim periods within those annual periods. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company early adopted ASU 2017-04 in the third quarter of 2019 and it did not have an impact on the Company’s consolidated financial statements.

In March 2017, the FASB issued ASU 2017-08, Receivables – Nonrefundable Fees and Other Costs (Subtopic 310-20), Premium Amortization on Purchased Callable Debt Securities, which shortens the amortization period for certain callable debt securities held at a premium. Specifically, the amendments require the premium to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. ASU 2017-08 became effective for public entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The Company adopted ASU 2017-08 in the first quarter of 2019 and it did not have a material impact on the Company’s consolidated financial statements.

New Accounting Standards Not Yet Adopted:

In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which along with several other subsequent codification updates related to accounting for credit losses, sets forth a “current expected credit loss” ("CECL") model requiring the Company to measure all expected credit losses for financial instruments recorded at amortized cost held at the reporting date. The estimate is to be based on historical experience, current conditions and reasonable and supportable forecasts. This replaces the existing incurred loss model and is applicable to the measurement of credit losses on financial assets measured at amortized cost and applies to some off-balance sheet credit exposures. The amendments are effective for the Company beginning January 1, 2020. Southern National engaged a third-party to collect data that was needed to produce historical inputs into any models created as a result of adopting this ASU. We have had our models validated and are currently evaluating the results and certain changes to our models. We currently expect the adoption of this ASU will result in an increase of approximately $10.0 million to $15.0 million in our allowance for loan losses, including transfers of non-accretable discount on purchased credit-impaired loans. As we are currently finalizing the execution of our implementation controls and processes, the ultimate impact of the adoption of this ASU could materially differ from our current expectation. The expected increase is a result of changing from an “incurred loss” model, which encompasses allowances for current known and inherent losses within the portfolio, to an “expected loss” model, which encompasses allowances for losses expected to be incurred over the life of the portfolio. The adoption of this ASU requires that we establish an allowance for expected credit losses for certain debt securities and other financial assets; however, we do not expect these allowances to be material. We plan to elect the federal banking agencies’ rule providing for an optional three-year phase-in period for the day-one adverse regulatory capital effects upon adopting the standard. The adoption of this ASU is not expected to have a significant impact on our regulatory capital ratios.

In August 2018, FASB issued ASU 2018-13, Fair Value measurement (Topic 820). This ASU adds, eliminates and modifies certain disclosure requirements for fair value measurements. The amendments in ASU 2018-13 are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted. The disclosures are effective using the prospective method for certain disclosures and retrospective for a majority of the disclosures. Southern National is currently in the process of evaluating the impact of adopting the new guidance on its consolidated financial statements and disclosures.

In December 2019, FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes (Topic 740). This ASU simplifies the accounting for income taxes by eliminating certain exceptions to the guidance in ASC 740 related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the recognition for deferred tax liabilities for outside basis differences. This ASU also simplifies aspects of the accounting for franchise taxes and enacted changes in tax laws or rates and clarifies the accounting transactions that result in a step-up in the tax basis of goodwill. ASU 2019-12 is effective for annual periods beginning after December 15, 2020, including interim periods within those annual periods. Early adoption is permitted. Southern National is currently in the process of evaluating the impact of adopting the new guidance on its consolidated financial statements and disclosures.
