Reclassification

Certain amounts reported in prior years have been reclassified to conform to the current year’s presentation. These reclassifications had no effect on the Company’s results of operations, financial position, or net cash flow.

Basis of Consolidation

The consolidated financial statements include the accounts of the Company and other entities in which it has a controlling financial interest. All significant intercompany balances and transactions have been eliminated in consolidation. Non-controlling interest consists of preferred shares in the Company's real estate investment trusts, SF Realty 1, Inc., SF FLA Realty, Inc., SF GA Realty, Inc. and SF TN Realty, Inc. that are owned by third parties.  The preferred shares in the real estate investment trusts receive dividends, which are included in the consolidated statements of income shown as income to non-controlling interest, and are redeemable at the Company's option. 

Debt Securities

Debt securities are classified based on the Company’s intention on the date of purchase. All debt securities classified as available-for-sale are recorded at fair value with any unrealized gains and losses reported in accumulated other comprehensive income (loss), net of the deferred income tax effects. Debt securities that the Company has the positive intent and ability to hold to maturity are classified as held-to-maturity and are carried at historical cost and adjusted for amortization of premiums and accretion of discounts.

Transfers of debt securities into the held-to-maturity category from available-for-sale category are made at fair value at the date of transfer. The unrealized holding gain or loss at the date of transfer is retained in other comprehensive income and in the carrying value of the held-to-maturity securities. Such amounts are amortized over the remaining life of the security.

Interest and dividends on securities, including amortization of premiums and accretion of discounts calculated under the effective interest method, are included in interest income. For certain securities, amortization of premiums and accretion of discounts is computed based on the anticipated life of the security which may be shorter than the stated life of the security. Realized gains and losses from the sale of securities are determined using the specific identification method and are recorded on the trade date of the sale.

Mortgage Loans Held for Sale

The Company classifies certain residential mortgage loans as held for sale. Typically, mortgage loans held for sale are sold to a third-party investor within a very short time period. The loans are sold without recourse and servicing is not retained. Net fees earned from this banking service are recorded in noninterest income.

In the course of originating mortgage loans and selling those loans in the secondary market, the Company makes various representations and warranties to the purchaser of the mortgage loans. Each loan is underwritten using government agency guidelines. Any exceptions noted during this process are remedied prior to sale. These representations and warranties also apply to underwriting the real estate appraisal opinion of value for the collateral securing these loans. Under the representations and warranties, failure by the Company to comply with the underwriting and/or appraisal standards could result in the Company being required to repurchase the mortgage loan or to reimburse the investor for losses incurred (make whole requests) if such failure cannot be cured by the Company within the specified period following discovery. The Company continues to experience an insignificant level of investor repurchase demands. There were no expenses incurred as part of these buyback obligations for the years ended December 31, 2022 and 2021.

Allowance for Credit Losses (“ACL”) and Impairment of Debt Securities

As described below under Recently Adopted Accounting Pronouncements, the Company adopted Accounting Standards Update (“ASU”) 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“CECL”) Accounting Standard Codification (“ASC”) 326 effective January 1, 2020.

ACL – Debt Securities Held to Maturity

Management uses a systematic methodology to determine its ACL for held-to-maturity debt securities. The ACL is a contra-asset valuation account that is deducted from the amortized cost basis to present the net amount expected to be collected on the held-to-maturity portfolio. Management considers the effects of past events, current conditions, and reasonable and supportable forecasts on the collectability of the portfolio. The Company’s estimate of its ACL involves a high degree of judgment; therefore, Management’s process for determining expected credit losses may result in a range of expected credit losses. Management monitors the held-to-maturity portfolio to determine whether an ACL would need to be recorded. As of December 31, 2022 and 2021, the Company had $1.03 billion and $463.0 million, respectively, of held-to-maturity securities and no related ACL recorded, respectively.

Impairment of Debt Securities Available for Sale

For available-for-sale debt securities in an unrealized loss position, the Company will first assess whether i) it intends to sell or ii) it is more likely than not that it will be required to sell the debt security before recovery of its amortized cost basis. If either case is applicable, any previously recognized allowances are charged off and the debt security’s amortized cost is written down to fair value through income. If neither case is applicable, the debt security is evaluated to determine whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, the Company considers the extent to which fair value is less than amortized cost, any changes to the rating of the debt security by a rating agency and any adverse conditions specifically related to the debt security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the debt security are compared to the amortized cost basis of the debt security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded for the credit loss, limited by the amount by which the fair value is less than the amortized cost basis. Any impairment that has not been recorded through allowance for credit losses is recognized in other comprehensive income, net of tax.

Adjustments to the allowance are reported in the income statement as a component of credit loss expense. Debt securities are charged off against the allowance or, in the absence of any allowance, written down through income when deemed uncollectible by the Company or when either of the aforementioned criteria regarding intent or requirement to sell is met specifically for available-for-sale debt securities.

The Company excludes the accrued interest receivable balance from the amortized cost basis in measuring expected credit losses on debt securities and does not record an ACL on accrued interest receivable.

ACL – Loans

The ACL is based on the Company’s evaluation of the loan portfolios, past loan loss experience, current asset quality trends, known and inherent risks in the portfolio, adverse situations that  may affect the borrower’s ability to repay (including the timing of future payment), the estimated value of any underlying collateral, composition of the loan portfolio, economic conditions, industry and peer bank loan quality indications and other pertinent factors, including regulatory recommendations. The process is inherently subjective and subject to significant change as it requires material estimates. The allowance is increased by a provision for credit losses, which is charged to expense, and reduced by charge-offs, net of recoveries. In addition, various regulatory agencies, as an integral part of their examination process, periodically review the allowance for credit losses. Such agencies may require the Company to recognize adjustments to the allowance based on their judgments about information available to them at the time of their examination.

Loans with similar risk characteristics are evaluated in pools and, depending on the nature of each identified pool, the Company utilizes a discounted cash flow (“DCF”), probability of default / loss given default (“PD/LGD”) or remaining life method. The historical loss experience estimate by pool is then adjusted by forecast factors that are quantitatively related to the Company’s historical credit loss experience, such as national unemployment rates and gross domestic product. Losses are predicted over a period of time determined to be reasonable and supportable, and at the end of the reasonable and supportable period losses are reverted to long term historical averages. The reasonable and supportable period and reversion period are re-evaluated each quarter by the Company and are dependent on the current economic environment among other factors.

The estimated credit losses for each loan pool are then adjusted for changes in qualitative factors not inherently considered in the quantitative analyses. The qualitative adjustments either increase or decrease the quantitative model estimation. The Company considers factors that are relevant within the qualitative framework which include the following: lending policy, changes in nature and volume of loans, staff experience, changes in volume and trends of problem loans, concentration risk, trends in underlying collateral values, external factors, quality of loan review system and other economic conditions.

Credit losses for loans that no longer share similar risk characteristics with the collectively evaluated pools are excluded from the collective evaluation and estimated on an individual basis. Individual evaluations are performed for nonaccrual loans, loans rated substandard, and modified loans classified as troubled debt restructurings. Specific allowances were estimated based on one of several methods, including the estimated fair value of the underlying collateral, observable market value of similar debt or the present value of expected cash flows.

The Company measures expected credit losses over the contractual term of a loan, adjusted for estimated prepayments. The contractual term excludes expected extensions, renewals and modifications unless there is a reasonable expectation that a troubled debt restructuring will be executed. Credit losses are estimated on the amortized cost basis of loans, which includes the principal balance outstanding, purchase discounts and premiums and deferred loan fees and costs. Accrued interest receivable on loans is excluded from the estimate of credit losses.

ACL – Unfunded Loan Commitments

The ACL is a liability account representing expected credit losses over the contractual period for which the Company is exposed to credit risk resulting from a contractual obligation to extend credit. No allowance is recognized if the Company has the unconditional right to cancel the obligation. The ACL is reported as a component of other liabilities within the Consolidated Balance Sheets. Adjustments to the ACL for unfunded commitments are reported in the Consolidated Income Statements  as a component of other operating expense.

Premises and Equipment

Land is carried at cost. Premises and equipment are carried at cost less accumulated depreciation. Expenditures for additions and major improvements that significantly extend the useful lives of the assets are capitalized. Expenditures for repairs and maintenance are charged to expense as incurred. Assets which are disposed of are removed from the accounts and the resulting gains or losses are recorded in operations. Depreciation is calculated on a straight-line basis over the estimated useful lives of the related assets (3 to 39.5 years).

Leasehold improvements are amortized on a straight-line basis over the lesser of the lease terms or the estimated useful lives of the improvements.

Bank Owned Life Insurance (“BOLI”)

BOLI is comprised of long-term life insurance contracts on the lives of certain current and past employees where the insurance policy benefit and ownership are retained by the employer. Its cash surrender value is an asset that the Company uses to partially offset the future cost of employee benefits. The cash surrender value accumulation on BOLI is permanently tax deferred if the policy is held to the insured person’s death and certain other conditions are met.

Derivatives and Hedging Activities

As part of its overall interest rate risk management, the Company uses derivative instruments, which can include interest rate swaps, caps, and floors. All derivative instruments are carried at fair value on the Consolidated Balance Sheets. Accounting standards provide special accounting provisions for derivative instruments that qualify for hedge accounting. To be eligible, the Company must specifically identify a derivative as a hedging instrument and identify the risk being hedged. The derivative instrument must be shown to meet specific requirements under this accounting standard.

The Company designates the derivative on the date the derivative contract is entered into as a hedge of the (1) fair value of a recognized asset or liability or of an unrecognized firm commitment (a “fair-value” hedge) or (2) a forecasted transaction of the variability of cash flows to be received or paid related to a recognized asset or liability (a “cash-flow” hedge). Changes in the fair value of a derivative that is highly effective as a fair-value hedge, and that is designated and qualifies as a fair-value hedge, along with the loss or gain on the hedged asset or liability that is attributable to the hedged risk (including losses or gains on firm commitments), are recorded in current-period earnings. The changes in a derivative’s fair value for a derivative that is highly effective and that is designated and qualifies as a cash-flow hedge are recorded in other comprehensive income until earnings are affected by the variability of cash flows (e.g., when periodic settlements on a variable-rate asset or liability are recorded in earnings).

The Company formally documents all relationships between hedging instruments and hedged items, as well as its risk-management objective and strategy for undertaking various hedge transactions. This process includes linking all derivatives that are designated as fair-value or cash-flow hedges to specific assets and liabilities on the Consolidated Balance Sheets or to specific firm commitments or forecasted transactions. The Company also formally assesses, both at the hedge’s inception and on an ongoing basis, as necessary, whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in fair values or cash flows of hedged items. When it is determined that a derivative is not highly effective as a hedge or that it has ceased to be a highly effective hedge, the Company discontinues hedge accounting prospectively, as discussed below. The Company discontinues hedge accounting prospectively when: (1) it is determined that the derivative is no longer effective in offsetting changes in the fair value or cash flows of a hedged item (including firm commitments or forecasted transactions); (2) the derivative expires or is sold, terminated, or exercised; (3) the derivative is re-designated as a hedge instrument, because it is unlikely that a forecasted transaction will occur; (4) a hedged firm commitment no longer meets the definition of a firm commitment; or (5) management determines that designation of the derivative as a hedge instrument is no longer appropriate.

When hedge accounting is discontinued because it is determined that the derivative no longer qualifies as an effective fair-value hedge, hedge accounting is discontinued prospectively and the derivative will continue to be carried on the balance sheet at its fair value with all changes in fair value being recorded in earnings but with no offsetting fair value adjustment being recorded on the hedged item. For a discontinued cash flow hedge the change in fair value is no longer recorded in other comprehensive income.

The Company uses derivatives to hedge interest rate exposures associated with mortgage loan originations. Interest rate lock commitments related to loans that are originated for later sale are classified as derivatives.  In the normal course of business, the Company regularly extends these rate lock commitments to customers during the loan origination process.  The fair values of the Company’s rate lock commitments to customers as of December 31, 2022 and 2021 were not material and have not been recorded.

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.

The Company uses the provisions of ASC 740-10, Income Taxes. ASC 740-10 establishes a single model to address accounting for uncertain tax positions which prescribes a minimum recognition threshold a tax position is required to meet before being recognized in the financial statements. There is a two-step process in the evaluation of a tax position. The first step is recognition. A Company determines whether it is more likely than not that a tax position will be sustained upon examination, including a resolution of any related appeals or litigation processes, based upon the technical merits of the position. The second step is measurement. A tax position that meets the more likely than not recognition threshold is measured at the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settlement.

Earnings per Common Share

Basic earnings per common share are computed by dividing net income available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted earnings per common share include the dilutive effect of additional potential common shares issuable under stock options and performance shares.

Fair Value of Financial Instruments

Fair values of financial instruments are estimated using relevant market information and other assumptions, as more fully disclosed in Note 21. Fair value estimates involve uncertainties and matters of significant judgment regarding interest rates, credit risk, 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.

Advertising

Advertising costs are expensed as incurred. Advertising expense for the years ended December 31, 2022, 2021 and 2020 was $447,000, $499,000 and $338,000, respectively. Advertising typically consists of local print media aimed at businesses that the Company targets as well as sponsorships of local events in which the Company’s clients and prospects are involved.
