NOTE 1 – Summary of Significant Accounting Policies and Activities

Southern First Bancshares, Inc. (the "Company") is a South Carolina corporation that owns all of the capital stock of Southern First Bank (the "Bank") and all of the stock of Greenville First Statutory Trust I and II (collectively, the "Trusts"). The Trusts are special purpose non-consolidated entities organized for the sole purpose of issuing trust preferred securities. The Bank's primary federal regulator is the Federal Deposit Insurance Corporation (the "FDIC"). The Bank is also regulated and examined by the South Carolina Board of Financial Institutions. The Bank is primarily engaged in the business of accepting demand deposits and savings deposits insured by the FDIC, and providing commercial, consumer and mortgage loans to the general public.

Basis of Presentation

The accompanying consolidated financial statements include the accounts of the Company and its wholly owned subsidiary, Southern First Bank. In consolidation, all significant intercompany transactions have been eliminated. The accounting and reporting policies conform to accounting principles generally accepted in the United States of America. In accordance with guidance issued by the Financial Accounting Standards Board (“FASB”), the operations of the Trusts have not been consolidated in these financial statements.

Business Segments

ASC Topic 280-10, “Segment Reporting,” requires selected segment information of operating segments based on a management approach. The Company’s three reportable segments represent the distinct product lines the Company offers and are viewed separately for strategic planning by management. Please refer to “Note 23 – Reportable Segments” for further information on the reporting for the Company’s three business segments.

Use of Estimates

The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America 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 consolidated financial statements and the reported amount of income and expenses during the reporting periods. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, derivatives, real estate acquired in settlement of loans, fair value of financial instruments, evaluating other-than-temporary-impairment of investment securities and valuation of deferred tax assets.

Risks and Uncertainties

In the normal course of its business, the Company encounters two significant types of risks: economic and regulatory. There are three main components of economic risk: interest rate risk, credit risk and market risk. The Company is subject to interest rate risk to the degree that its interest-bearing liabilities mature or reprice at different speeds, or on different bases, than its interest-earning assets. Credit risk is the risk of default within the Company’s loan portfolio that results from borrowers’ inability or unwillingness to make contractually required payments. Market risk reflects changes in the value of collateral underlying loans receivable and the valuation of real estate held by the Company.

The Company is subject to the regulations of various governmental agencies. These regulations can and do change significantly from period to period. The Company also undergoes periodic examinations by the regulatory agencies, which may subject it to changes with respect to valuation of assets, amount of required loan loss allowance and operating restrictions resulting from the regulators’ judgments based on information available to them at the time of their examinations.

The Bank makes loans to individuals and businesses in the Upstate, Midlands, and Lowcountry regions of South Carolina as well as the Triangle and Triad regions of North Carolina and Atlanta, Georgia for various personal and commercial purposes. The Bank’s loan portfolio has a concentration of real estate loans. As of December 31, 2018 and 2017, real estate loans represented 82.3% and 82.1%, respectively, of total loans. However, borrowers’ ability to repay their loans is not dependent upon any specific economic sector.

Subsequent Events

Subsequent events are events or transactions that occur after the balance sheet date but before financial statements are issued. Recognized subsequent events are events or transactions that provide additional evidence about conditions that existed at the date of the balance sheet, including the estimates inherent in the process of preparing financial statements. Non-recognized subsequent events are events that provide evidence about conditions that did not exist at the date of the balance sheet but arose after that date. Management performed an evaluation to determine whether there have been any subsequent events since the balance sheet date and determined that no subsequent events occurred requiring accrual or disclosure.

Reclassifications

Certain amounts, previously reported, have been reclassified to state all periods on a comparable basis and had no effect on shareholders’ equity or net income.

Cash and Cash Equivalents

Cash and cash equivalents include cash and due from banks, interest bearing deposits and federal funds sold. Cash and cash equivalents have original maturities of three months or less, and federal funds sold are generally purchased and sold for one-day periods. Accordingly, the carrying value of these instruments is deemed to be a reasonable estimate of fair value. At December 31, 2018 and 2017, included in cash and cash equivalents was $4.9 million and $7.3 million, respectively, on deposit with the Federal Reserve Bank.

Investment Securities

We classify our investment securities as held to maturity securities, trading securities and available for sale securities as applicable.

Investment securities are designated as held to maturity if we have the intent and the ability to hold the securities to maturity. Held to maturity securities are carried at amortized cost, adjusted for the amortization of any related premiums or the accretion of any related discounts into interest income using a methodology which approximates a level yield of interest over the estimated remaining period until maturity. Unrealized losses on held to maturity securities, reflecting a decline in value judged by us to be other than temporary, are charged to income in the Consolidated Statements of Income.

Investment securities that are purchased and held principally for the purpose of selling in the near term are reported as trading securities. Trading securities are carried at fair value with unrealized holding gains and losses included in earnings.

We classify investment securities as available for sale when at the time of purchase we determine that such securities may be sold at a future date or if we do not have the intent or ability to hold such securities to maturity. Securities designated as available for sale are recorded at fair value. Changes in the fair value of debt and equity securities available for sale are included in shareholders’ equity as unrealized gains or losses, net of the related tax effect. Unrealized losses on available for sale securities, reflecting a decline in value judged to be other than temporary, are charged to income in the Consolidated Statements of Income. Realized gains or losses on available for sale securities are computed on the specific identification basis.

Other Investments

The Bank, as a member institution, is required to own a stock investment in the Federal Home Loan Bank of Atlanta (“FHLB”). This stock is generally pledged against any borrowings from the FHLB and cash dividends on our FHLB stock are recorded in investment income. No ready market exists for these stocks and they have no quoted market value. However, redemption of this stock has historically been at par value. Other investments also include a $403,000 investment in the Trusts.

Loans

Loans are stated at the principal balance outstanding. Unamortized net loan fees and the allowance for possible loan losses are deducted from total loans on the balance sheets. Interest income is recognized over the term of the loan based on the principal amount outstanding. The net of loan origination fees received and direct costs incurred in the origination of loans is deferred and amortized to interest income over the contractual life of the loans adjusted for actual principal prepayments using a method approximating the interest method.

Nonaccrual and Past Due Loans

Loans are generally placed on nonaccrual status when principal or interest becomes 90 days past due, or when payment in full is not anticipated. When a loan is placed on nonaccrual status, interest accrued but not received is generally reversed against interest income. Cash receipts on nonaccrual loans are not recorded as interest income, but are used to reduce the loan’s principal balance. A nonaccrual loan is generally returned to accrual status and accrual of interest is resumed when payments have been made according to the terms and conditions of the loan for a continuous six month period. Our loans are considered past due when contractually required principal or interest payments have not been made on the due dates.

Nonperforming Assets

Nonperforming assets include real estate acquired through foreclosure or deed taken in lieu of foreclosure, loans on nonaccrual status and loans past due 90 days or more and still accruing interest. Loans are placed on nonaccrual status when, in the opinion of management, the collection of additional interest is uncertain. Thereafter no interest is taken into income until such time as the borrower demonstrates the ability to pay both principal and interest.

Impaired Loans

Our impaired loans include loans on nonaccrual status and loans modified in a troubled debt restructuring (“TDR”), whether on accrual or nonaccrual status. For loans that are classified as impaired, an allowance is established when the fair value (discounted cash flows, collateral value, or observable market price) of the impaired loan less costs to sell, are lower than the carrying value of that loan. A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due, among other factors. 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, without limitation, 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 for commercial and construction loans 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. Prior to this change, large groups of smaller balance homogeneous consumer loans were collectively evaluated for impairment, and we did not separately identify individual consumer loans for impairment disclosures.

Loan Charge-off Policy

For commercial loans, we generally fully charge off or charge collateralized loans down to net realizable value when management determines the loan to be uncollectible; repayment is deemed to be projected beyond reasonable time frames; the loan has been classified as a loss by either our internal loan review process or our banking regulatory agencies; the client has filed bankruptcy and the loss becomes evident owing to a lack of assets; or the loan is 120 days past due unless both well-secured and in the process of collection. For consumer loans, we generally charge down to net realizable value when the loan is 180 days past due.

Troubled Debt Restructuring (TDRs)

The Company considers a loan to be a TDR when the debtor experiences financial difficulties and the Company provides concessions such that we will not collect all principal and interest in accordance with the original terms of the loan agreement. Concessions can relate to the contractual interest rate, maturity date, or payment structure of the note. As part of our workout plan for individual loan relationships, we may restructure loan terms to assist borrowers facing challenges in the current economic environment.

Our policy with respect to accrual of interest on loans restructured in a TDR follows relevant supervisory guidance. That is, if a borrower has demonstrated performance under the previous loan terms and shows capacity to perform under the restructured loan terms; continued accrual of interest at the restructured interest rate is likely. If a borrower was materially delinquent on payments prior to the restructuring, but shows capacity to meet the restructured loan terms, the loan will likely continue as nonaccrual going forward. Lastly, if the borrower does not perform under the restructured terms, the loan is placed on nonaccrual status. We will continue to closely monitor these loans and will cease accruing interest on them if management believes that the borrowers may not continue performing based on the restructured note terms. If, after previously being classified as a TDR, a loan is restructured a second time and the borrower continues to experience financial difficulties, then that loan is automatically placed on nonaccrual status. Our policy with respect to nonperforming loans requires the borrower to make a minimum of six consecutive payments of principal and interest in accordance with the loan terms before that loan can be placed back on accrual status. Further, the borrower must show capacity to continue performing into the future prior to restoration of accrual status. In addition, our policy, in accordance with supervisory guidance, also provides for a loan to be removed from TDR status if the loan is modified or renewed at terms consistent with current market rates and the loan has been performing under modified terms for an extended period of time or under certain circumstances.

In the determination of the allowance for loan losses, management considers TDRs on commercial and consumer loans and subsequent defaults in these restructurings by measuring impairment, on a loan by loan basis, based on 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, less costs to sell, if the loan is collateral dependent.

Allowance for Loan Losses

The allowance for loan losses is management’s estimate of credit losses inherent in the loan portfolio. The allowance for loan losses is established as losses are estimated to have occurred through a provision for loan losses charged to earnings. Loan losses are charged against the allowance when management believes the uncollectibility of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. The allowance for loan losses is evaluated on a regular basis by management and is based upon management’s periodic review of the collectability of the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, the estimated value of any underlying collateral and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available.

We have an established process to determine the adequacy of the allowance for loan losses that assesses the losses inherent in our portfolio. While we attribute portions of the allowance to specific portfolio segments, the entire allowance is available to absorb credit losses inherent in the total loan portfolio. Our process involves procedures to appropriately consider the unique risk characteristics of our commercial and consumer loan portfolio segments. For each portfolio segment, impairment is measured individually for each impaired loan. Our allowance levels are influenced by loan volume, loan grade or delinquency status, historic loss experience and other economic conditions. See Note 4 to the Consolidated Financial Statements for additional information on the allowance for loan losses.

Other Real Estate Owned

Real estate acquired through foreclosure is initially recorded at the lower of cost or estimated fair value less selling costs. Subsequent to the date of acquisition, it is carried at the lower of cost or fair value, adjusted for net selling costs. Fair values of real estate owned are reviewed regularly and write-downs are recorded when it is determined that the carrying value of real estate exceeds the fair value less estimated costs to sell. Costs relating to the development and improvement of such property are capitalized, whereas those costs relating to holding the property are expensed.

Property and Equipment

Property and equipment are stated at cost. Major repairs are charged to operations, while major improvements are capitalized. Depreciation is computed using the straight-line method over the estimated useful lives of the related assets. Upon retirement, sale, or other disposition of property and equipment, the cost and accumulated depreciation are eliminated from the accounts, and gain or loss is included in income from operations.

Construction in progress is stated at cost, which includes the cost of construction and other direct costs attributable to the construction. No provision for depreciation is made on construction in progress until such time as the relevant assets are completed and put into use.

Bank Owned Life Insurance Policies

Bank owned life insurance policies represent the cash value of policies on certain officers of the Company.

Securities Sold Under Agreements to Repurchase

The Bank enters into sales of securities under agreements to repurchase (reverse repurchase agreements). Repurchase agreements are treated as financing, with the obligation to repurchase securities sold being reflected as a liability and the securities underlying the agreements remaining as assets in the Consolidated Balance Sheets.

Comprehensive Income

Comprehensive income (loss) consists of net income and net unrealized gains (losses) on securities and is presented in the statements of shareholders’ equity and comprehensive income. The statement requires only additional disclosures in the consolidated financial statements; it does not affect our results of operations.

Revenue from Contracts with Customers

The Company records revenue from contracts with customers in accordance with Accounting Standards Codification Topic 606, “Revenue from Contracts with Customers” (“Topic 606”). Under Topic 606, the Company must identify the contract with a customer, identify the performance obligations in the contract, determine the transaction price, allocate the transaction price to the performance obligations in the contract, and recognize revenue when (or as) the Company satisfies a performance obligation. Significant revenue has not been recognized in the current reporting period that results from performance obligations satisfied in previous periods.

The Company’s primary sources of revenue are derived from interest and dividends earned on loans, investment securities, and other financial instruments that are not within the scope of Topic 606. The Company has evaluated the nature of its contracts with customers and determined that further disaggregation of revenue from contracts with customers into more granular categories beyond what is presented in the Consolidated Statements of Income was not necessary. The Company generally fully satisfies its performance obligations on its contracts with customers as services are rendered and the transaction prices are typically fixed; charged either on a periodic basis or based on activity. Our accounting policies will not change materially since the principles of revenue recognition from the Accounting Standards Update are largely consistent with existing guidance and current practices applied by our business. The following is a discussion of revenues within the scope of the new guidance:

●	Service fees on deposit accounts - The Company earns fees from its deposit clients for various transaction-based, account maintenance, and overdraft or non-sufficient funds (“NSF”) services. Transaction-based fees, which include services such as stop payment charges, statement rendering, and ACH fees, are recognized at the time the transaction is executed as that is the point in time the Company fulfills the client's request. Account maintenance fees, which relate primarily to monthly maintenance and account management, are earned over the course of a month, representing the period over which the Company satisfies the performance obligation. Overdraft and NSF fees are recognized at the point in time that the overdraft occurs or the NSF item is presented. Service charges on deposits are withdrawn from the client's account balance.

●	ATM and debit card income - The Company earns interchange fees from debit cardholder transactions conducted through the payment networks. Interchange fees from cardholder transactions represent a percentage of the underlying transaction value and are recognized daily, concurrently with the transaction processing services provided to the cardholder.

Income Taxes

The financial statements have been prepared on the accrual basis. When income and expenses are recognized in different periods for financial reporting purposes versus for the purposes of computing income taxes currently payable, deferred taxes are provided on such temporary differences. Deferred tax assets and liabilities are recognized for the expected future tax consequences of events that have been recognized in the consolidated financial statements or tax returns. Deferred tax assets and liabilities are measured using the enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be realized or settled. The Company believes that its income tax filing positions taken or expected to be taken on its tax returns will more likely than not be sustained upon audit by the taxing authorities and does not anticipate any adjustments that will result in a material adverse impact on the Company’s financial condition, results of operations, or cash flow. Therefore, no reserves for uncertain income tax positions have been recorded. The Company’s federal and state income tax returns are open and subject to examination from the 2015 tax return year and forward.

On December 22, 2017, the Tax Act was signed into law and includes numerous provisions that impact the Company, most notably a reduction in the corporate tax rate from the maximum rate of 35% to a flat rate of 21%. As a result, the Company recorded an incremental income tax expense of $2.4 million in the fourth quarter of 2017. During the fourth quarter of 2018, the Company completed its accounting for the income tax effects related to the Tax Act which resulted in no change to the provisional adjustment recorded in income tax expense in 2017.

Stock-Based Compensation

The Company has a stock-based employee compensation plan. Compensation cost is recognized for all stock options granted and for any outstanding unvested awards as if the fair value method had been applied to those awards as of the date of grant.

Adoption of New Accounting Standards

In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers”, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU replaces most existing revenue recognition guidance in GAAP. The new standard was effective for the Company on January 1, 2018. Adoption of ASU 2014-09 did not have a material impact on the Company’s consolidated financial statements and related disclosures as the Company’s primary sources of revenues are derived from interest and dividends earned on loans, investment securities, and other financial instruments that are not within the scope of ASU 2014-09. The Company’s revenue recognition pattern for revenue streams within the scope of ASU 2014-09, including but not limited to service charges on deposit accounts, ATM and debit card income, and gains/losses on the sale of other real estate owned, did not change significantly from current practice. The standard permits the use of either the full retrospective or modified retrospective transition method. The Company elected to use the modified retrospective transition method which requires application of ASU 2014-09 to uncompleted contracts at the date of adoption however, periods prior to the date of adoption will not be retrospectively revised as the impact of the ASU on uncompleted contracts at the date of adoption was not material.

In January 2016, the FASB issued ASU No. 2016-01, “Financial Instruments – Overall: Recognition and Measurement of Financial Assets and Financial Liabilities”. The guidance affects the accounting for equity investments, financial liabilities under the fair value option and the presentation and disclosure requirements of financial instruments. ASU 2016-01 was effective for the Company on January 1, 2018 and resulted in the use of an exit price rather than an entrance price to determine the fair value of loans not measured at fair value on a non-recurring basis in the consolidated balance sheets. See Note 13 – Fair Value Accounting for further information regarding the valuation of these loans.

In August 2016, the FASB amended the Statement of Cash Flows topic of the Accounting Standards Codification to clarify how certain cash receipts and cash payments are presented and classified in the statement of cash flows. In November 2016, the FASB again amended the Statement of Cash Flows topic to clarify how restricted cash is presented and classified in the statement of cash flows. The amendments were effective for the Company for fiscal years beginning after December 15, 2017 including interim periods within those fiscal years. These amendments did not have a material effect on the Company’s financial statements.

In May 2017, the FASB amended the requirements in the Compensation—Stock Compensation Topic of the Accounting Standards Codification related to changes to the terms or conditions of a share-based payment award. The amendments provide guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting. The amendments were effective for the Company for annual periods, and interim periods within those annual periods, beginning after December 15, 2017 and did not have a material effect on its financial statements.

In February 2018, the FASB amended certain aspects of the guidance issued in ASU 2016-01, the Financial Instruments Topic of the ASC. The amendments clarify certain aspects of the guidance issued in ASU 2016-01. The amendments were effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years beginning after June 15, 2018 and did not have a material effect on the Company’s financial statements.

In February 2018, the FASB issued ASU 2018-02, Income Statement (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, which requires Companies to reclassify the stranded effects in other comprehensive income to retained earnings as a result of the change in the tax rates under the Tax Cuts and Jobs Act. The Company has opted to early adopt this pronouncement by retrospective application to each period (or periods) in which the effect of the change in the tax rate under the Tax Act is recognized. The impact of the reclassification from other comprehensive income to retained earnings did not have a material effect on the Company’s financial statements.

Newly Issued, But Not yet Effective Accounting Standards

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. The Company expects that the adoption of ASU 2016-02 will result in the recognition of lease liabilities totaling approximately $18.5 million and the recognition of right-of-use assets totaling approximately $18.5 million. The initial balance sheet gross up upon adoption is primarily related to operating leases of certain real estate properties. The Company has no material leasing arrangements for which it is the lessor of property or equipment. The amendments in this ASU are effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2018. The Company expects to apply ASU 2016-02 as of the beginning of the period of adoption (January 1, 2019) using the modified retrospective approach and practical expedients for transition and will not restate comparative periods. The practical expedients allow us to largely account for our existing leases consistent with current guidance except for the incremental balance sheet recognition for lessees. We have started an initial evaluation of our leasing contracts and activities. We have also started developing our methodology to estimate the right-of use assets and lease liabilities, which is based on the present value of lease payments (the December 31, 2018 future minimum lease payments were $15.7 million). We do not expect a material change to the timing of expense recognition but we will continue to evaluate the financial impact as implementation occurs. We are evaluating our existing disclosures and may need to provide additional information as a result of adoption of the ASU.

In June 2016, the FASB issued ASU 2016-13, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments”. Among other things, ASU 2016-13 requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Financial institutions and other organizations will now use forward-looking information to form their credit loss estimates. Many of the loss estimation techniques applied today will still be permitted, although the inputs to those techniques will change to reflect the full amount of expected credit losses. In addition, ASU 2016-13 amends the accounting for credit losses on debt securities and purchased financial assets with credit deterioration. ASU 2016-13 is effective for all annual and interim periods beginning after December 31, 2019, with early adoption permitted for fiscal years beginning after December 15, 2018. Adoption will be applied through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. The Company intends to adopt the guidance on January 1, 2020 and has established a team of individuals from credit, finance and risk management to evaluate the requirements of the new standard and the impact it will have on our processes. Our implementation plan has progressed through the initial design, build, and testing phase and, in the first quarter of 2019, we will begin running parallel models. While we continue to evaluate the impact the new guidance will have on our financial position and results of operations, we currently expect the new guidance may result in an increase to our allowance for credit losses given the change to estimated losses over the contractual life of the loan portfolio. The amount of any change to our allowance is still under review and will depend, in part, upon the composition of our loan portfolio at the adoption date as well as economic conditions and loss forecasts at that date.

In March 2017, the FASB amended the requirement in the Receivables-Nonrefundable Fees and Other Costs Topic of the ASC related to the amortization period for certain purchased callable debt securities held at a premium. The amendments shorten the amortization period for the premium to the earliest call date. The amendments were effective for the Company for interim and annual periods beginning after December 15, 2018. The Company does not expect these amendments to have a material effect on its financial statements.

Other accounting standards that have been issued or proposed by the FASB or other standards-setting bodies that do not require adoption until a future date are not expected to have a material impact on the consolidated financial statements upon adoption.
