Notes to Consolidated Financial Statements

1. Basis of Presentation

The accompanying unaudited consolidated financial statements were prepared in accordance with instructions for Form 10-Q and accounting principles generally accepted in the United States of America ("GAAP"); therefore, they do not include all disclosures necessary for a complete presentation of financial condition, results of operations, and cash flows.  Such statements are unaudited but, in the opinion of management, reflect all adjustments, which are of a normal recurring nature and necessary for a fair presentation of results for the selected interim periods.  Users of financial information produced for interim periods are encouraged to refer to the footnotes contained in the audited consolidated financial statements appearing in Security Federal Corporation’s (the “Company”) 2020 Annual Report to Shareholders which was filed as an exhibit to our Annual Report on Form 10-K for the year ended December 31, 2020 (“2020 10-K”) when reviewing interim financial statements. The unaudited consolidated results of operations for the nine months ended September 30, 2021 are not necessarily indicative of the results that may be expected for the year ending December 31, 2021 or any other period. The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

2. Principles of Consolidation

The accompanying unaudited consolidated financial statements include the accounts of the Company and its wholly owned subsidiary, Security Federal Bank (the “Bank”) and the Bank’s wholly owned subsidiaries, Security Federal Insurance, Inc. (“SFINS”), Security Federal Investments, Inc. ("SFINV") and Security Financial Services Corporation (“SFSC”). SFINS is an insurance agency offering auto, business, health and home insurance.  SFINS has a wholly owned subsidiary, Collier Jennings Financial Corporation, which has as subsidiaries Security Federal Auto Insurance, The Auto Insurance Store Inc., and Security Federal Premium Pay Plans Inc. Security Federal Premium Pay Plans Inc. has one wholly owned premium finance subsidiary and also has an ownership interest in four other premium finance subsidiaries. SFINV was formed to hold investment securities and allow for better management of the securities portfolio. SFSC is currently inactive. All significant intercompany transactions and balances have been eliminated in consolidation.

The Company has a wholly owned subsidiary, Security Federal Statutory Trust (the “Trust”), which issued and sold fixed and floating rate capital securities of the Trust.  However, under current accounting guidance, the Trust is not consolidated in the Company’s financial statements.  The Bank is primarily engaged in the business of accepting savings and demand deposits and originating mortgage loans and other loans to individuals and small businesses for various personal and commercial purposes.

3. Critical Accounting Policies

The Company has adopted various accounting policies, which govern the application of accounting principles generally accepted in the United States in the preparation of our financial statements. Our significant accounting policies are described in the footnotes to the audited consolidated financial statements at December 31, 2020 included in our 2020 Annual Report to Shareholders. Certain accounting policies involve significant judgments and assumptions by management, which have a material impact on the carrying value of certain assets and liabilities, and, as such, have a greater possibility of producing results that could be materially different than originally reported. We consider these accounting policies to be critical accounting policies.  The judgments and assumptions we use are based on historical experience and other factors, which we believe to be reasonable under the circumstances.  Because of the nature of the judgments and assumptions we make, actual results could differ from these judgments and estimates which could have a material impact on our carrying values of assets and liabilities and our results of operations.

The Company believes the allowance for loan losses is a critical accounting policy that requires the most significant judgments and estimates used in preparation of the consolidated financial statements.  The impact of an unexpected and sudden large loss could deplete the allowance and potentially require increased provisions to replenish the allowance, which would negatively affect earnings. The Company provides for loan losses using the allowance method.  Accordingly, all loan losses are charged to the related allowance and all recoveries are credited to the allowance for loan losses.  Additions to the allowance for loan losses are provided by charges to operations based on various factors, which, in management’s judgment, deserve current recognition in estimating possible losses.  Such factors considered by management include the fair value of the underlying collateral, stated guarantees by the borrower (if applicable), the borrower’s ability to repay from other economic resources, growth and composition of the loan portfolio, the relationship of the allowance for loan losses to the outstanding loans, loss experience, delinquency trends, and general economic conditions.  Management evaluates the carrying value of the loans periodically and the allowance is adjusted accordingly.

3. Critical Accounting Policies, Continued

While management uses the best information available to make evaluations, future adjustments may be necessary if economic conditions differ substantially from the assumptions used in making these evaluations.  The allowance for loan losses is subject to periodic evaluations by our bank regulatory agencies, including the Board of Governors of the Federal Reserve System ("Federal Reserve"), the FDIC and the South Carolina Board of Financial Institutions, which may require adjustments to be made to the allowance based upon the information that is available at the time of their examination.

The Company values impaired loans at the loan’s fair value if it is probable that the Company will be unable to collect all amounts due according to the terms of the loan agreement at the present value of expected cash flows, the market price of the loan, if available, or the value of the underlying collateral.  Expected cash flows are required to be discounted at the loan’s effective interest rate.  When the ultimate collectibility of an impaired loan’s principal is in doubt, wholly or partially, all cash receipts are applied to principal.  When this doubt does not exist, cash receipts are applied under the contractual terms of the loan agreement first to interest and then to principal.  Once the recorded principal balance has been reduced to zero, future cash receipts are applied to interest income to the extent that any interest has been foregone.  Further cash receipts are recorded as recoveries of any amounts previously charged off.

The Company uses assumptions and estimates in determining income taxes payable or refundable for the current year, deferred income tax liabilities and assets for events recognized differently in its financial statements and income tax returns, and income tax expense. Determining these amounts requires analysis of certain transactions and interpretation of tax laws and regulations. The Company exercises considerable judgment in evaluating the amount and timing of recognition of the resulting tax liabilities and assets. These judgments and estimates are reevaluated on a continual basis as regulatory and business factors change. No assurance can be given that either the tax returns submitted by us or the income tax reported on the consolidated financial statements will not be adjusted by either adverse rulings by the United States Tax Court, changes in the tax code, or assessments made by the Internal Revenue Service.

4. Earnings Per Share

Accounting guidance specifies the computation, presentation and disclosure requirements for earnings per share (“EPS”) for entities with publicly held common stock or potential common stock such as options, warrants, convertible securities or contingent stock agreements if those securities trade in a public market. Basic EPS is computed by dividing net income by the weighted average number of common shares outstanding.  Diluted EPS is similar to the computation of basic EPS except that the denominator is increased to include the number of additional common shares that would have been outstanding if the dilutive common shares had been issued.  The dilutive effect of options outstanding under the Company’s stock option plan is reflected in diluted EPS by application of the treasury stock method. There were no stock options outstanding at September 30, 2021 or 2020; and therefore, no dilutive options were included in the calculation of diluted EPS for those periods. The following tables include a summary of the Company's basic EPS for three and nine months ended September 30, 2021 and 2020.

	Three Months Ended September 30,
	2021					2020
	Income		Shares	EPS		Income		Shares	EPS
Basic EPS	$	4,642,470	3,252,884	$	1.43	$	904,711	3,252,884	$	0.28
	Nine Months Ended September 30,

Basic EPS	$	10,745,404	3,252,884	$	3.30	$	3,985,229	3,199,603	$	1.25

5. Stock-Based Compensation

Certain officers and directors of the Company participate in incentive and non-qualified stock option plans. Options are granted at exercise prices not less than the fair value of the Company’s common stock on the date of the grant. At September 30, 2021 and 2020, the Company had no options outstanding and there was no activity during both the nine months ended September 30, 2021 and 2020. At those dates, there were 50,000 options available for grants.

Student Loan Pools are typically 97% guaranteed by the United States government while SBA bonds are 100% backed by the full faith and credit of the United States government. The majority of the mortgage-backed securities included in the tables above and below are issued or guaranteed by an agency of the United States government such as Ginnie Mae, or by Government Sponsered Entities ("GSEs"), including Fannie Mae and Freddie Mac. Ginnie Mae mortgage-backed securities are backed by the full faith and credit of the United States government, while those issued by GSEs are not.

At September 30, 2021, AFS Ginnie Mae mortgage-backed securities had an amortized cost and fair value of $133.8 million and $133.9 million, respectively, compared to an amortized cost and fair value of $91.7 million and $93.4 million, respectively, at December 31, 2020.

Also included in mortgage-backed securities in the tables above and below are private label collateralized mortgage obligation ("CMO") securities, which are issued by non-governmental real estate mortgage investment conduits and are not backed by the full faith and credit of the United States government.  At September 30, 2021 the Bank held AFS private label CMO mortgage-backed securities with an amortized cost and fair value of $31.4 million and $31.6 million, compared to an amortized cost and fair value of $37.0 million and $37.7 million at December 31, 2020, respectively.

The amortized cost and fair value of investment and mortgage-backed securities available for sale at September 30, 2021 are shown below by contractual maturity.  Expected maturities will differ from contractual maturities because borrowers have the right to prepay obligations with or without call or prepayment penalties. Since mortgage-backed securities are not due at a single maturity date, they are disclosed separately, rather than allocated over the maturity groupings set forth in the table below.

At September 30, 2021 the amortized cost and fair value of investment and mortgage-backed securities available for sale pledged as collateral for certain deposit accounts, FHLB advances and other borrowings were $299.5 million and $309.0 million, respectively, compared to an amortized cost and fair value of $263.3 million and $274.4 million, respectively, at December 31, 2020.

There were no sales of available for sale securities during the nine months ended September 30, 2021. The Bank received $4.6 million and $25.0 million in gross proceeds from sales of available for sale securities during the three and nine months ended September 30, 2020, respectively. As a result, the Company recognized gross gains of $139,000 and $1.3 million during the three and nine months ended September 30, 2020, respectively, and no gross losses during the three and nine months ended September 30, 2020.

6. Investment and Mortgage-Backed Securities, Available For Sale, Continued

Securities classified as available for sale are recorded at fair market value.  At September 30, 2021 and December 31, 2020, 22.7% and 37.0% of the unrealized losses, representing 71 and 88 individual securities, respectively, consisted of securities in a continuous loss position for 12 months or more. The Company has the ability and intent to hold these securities until such time as the value recovers or the securities mature.  The Company believes, based on industry analyst reports and credit ratings, that the deterioration in value is attributable to changes in market interest rates and is not in the credit quality of the issuer and therefore, these losses are not considered other-than-temporary. The Company reviews its investment securities portfolio at least quarterly and more frequently when economic conditions warrant, assessing whether there is any indication of other-than-temporary impairment (“OTTI”).

Additional deterioration in market and economic conditions related to the novel coronavirus of 2019 (“COVID-19”) pandemic may, however, have an adverse impact on credit quality in the future and result in OTTI charges. Factors considered in the review include estimated future cash flows, length of time and extent to which market value has been less than cost, the financial condition and near term prospects of the issuer, and our intent and ability to retain the security to allow for an anticipated recovery in market value. If the review determines that there is OTTI, an impairment loss is recognized in earnings equal to the difference between the investment’s cost and its fair value at the balance sheet date of the reporting period for which the assessment is made, or the Company may recognize a portion in other comprehensive income. The fair value of investments on which OTTI is recognized then becomes the new cost basis of the investment. There was no OTTI recognized during the nine months ended September 30, 2021 and the year ended December 31, 2020.

7. Investment and Mortgage-Backed Securities, Held to Maturity

8.    Loans Receivable, Net, Continued

During the year ended December 31, 2020, the Bank participated in the initial SBA Paycheck Protection Program (“PPP”), a guaranteed unsecured loan program enacted under the Coronavirus Aid, Relief and Economic Security Act of 2020 (“CARES Act”) signed into law on March 27, 2020 to provide near-term relief to help small businesses impacted by COVID-19 sustain operations. PPP loans are fully guaranteed by the SBA. Loan originations under the initial PPP ended in August 2020. The Consolidated Appropriations Act, 2021 (“CAA 2021”) enacted on December 27, 2020, renewed and extended the PPP until May 31, 2021. As a result, in January 2021, the Bank began accepting and processing loan applications under this second PPP.

As of September 30, 2021, the Bank had originated nearly 2,800 PPP loans to new and existing customers, totaling approximately $127.6 million. The Bank earns 1% interest on PPP loans as well as a fee from the SBA to cover processing costs, which is amortized over the life of the loan. The maturity date of a PPP loan is either two or five years from the date of loan origination. As of September 30, 2021, we have recognized $4.5 million in PPP loans fees, including $3.3 million recognized in the nine months ended September 30, 2021. The balance of unamortized net deferred fees on PPP loans was $1.8 million at September 30, 2021 compared to $1.4 million at December 31, 2020. The Bank expects that the great majority of PPP borrowers will seek full or partial forgiveness of their loan obligations in accordance with the CARES Act. Because the SBA guarantees 100% of the PPP loans made to eligible borrowers, and the entire principal amount of these loans, including any accrued interest, is eligible to be forgiven and repaid by the SBA, PPP loans are excluded from our allowance for loan losses calculation. There were 696 PPP loans totaling $32.1 million in our loan portfolio at September 30, 2021.

The Company uses a risk based approach based on the following credit quality measures when analyzing the loan portfolio: pass, caution, special mention, and substandard. These indicators are used to rate the credit quality of loans for the purposes of determining the Company’s allowance for loan losses. Pass loans are loans that are performing and are deemed adequately protected by the net worth of the borrower or the underlying collateral value. These loans are considered to have the least amount of risk in terms of determining the allowance for loan losses. Loans that are graded as substandard are considered to have the most risk. These loans typically have an identified weakness or weaknesses and are inadequately protected by the net worth of the borrower or collateral value. All loans 90 days or more past due are automatically classified in this category. The caution and special mention categories fall in between the pass and substandard grades and consist of loans that do not currently expose the Company to sufficient risk to warrant adverse classification but possess weaknesses.

At September 30, 2021 and December 31, 2020, the Company did not have any loans that were 90 days or more past due and still accruing interest. The Company's strategy is to work with its borrowers to reach acceptable payment plans while protecting its interests in the existing collateral.  In the event an acceptable arrangement cannot be reached, the Company may have to acquire these properties through foreclosure or other means and subsequently sell, develop, or liquidate them.

Loans for which it is probable that payment of interest and principal will not be made in accordance with the contractual terms of the loan agreement are considered impaired. Non-accrual commercial loans under $200,000 and non-accrual consumer loans under $100,000 are considered immaterial and are excluded from the impairment review. Once a loan is identified as individually impaired, management measures the impairment and records the loan at fair value. Fair value is estimated using one of the following methods: fair value of the collateral less estimated costs to sell, discounted cash flows, or market value of the loan based on similar debt. The fair value of the collateral less estimated costs to sell is the most frequently used method.

Typically, the Company reviews the most recent appraisal and, if it is over 24 months old, will request a new third party appraisal. Depending on the particular circumstances surrounding the loan, including the location of the collateral, the date of the most recent appraisal and the value of the collateral relative to the recorded investment in the loan, management may order an independent appraisal immediately or, in some instances, may elect to perform an internal analysis. The average balance of impaired loans was $2.5 million and $2.6 million for the three and nine months ended September 30, 2021, respectively, compared to $3.3 million and $3.7 million for the three and nine months ended September 30, 2020, respectively.

In the course of resolving delinquent loans, the Company may choose to restructure the contractual terms of certain loans. A troubled debt restructuring ("TDR") is a restructuring in which the Company, for economic or legal reasons related to a borrower’s financial difficulties, grants a concession to a borrower that it would not otherwise consider (Financial Accounting Standards Board ("FASB") Accounting Standards Codification (“ASC”) Topic 310-40).  The concessions granted on TDRs generally include terms to reduce the interest rate, extend the term of the debt obligation, or modify the payment structure on the debt obligation. The Company grants such concessions to reassess the borrower’s financial status and develop a plan for repayment.  

19

SECURITY FEDERAL CORPORATION AND SUBSIDIARIES

Notes to Consolidated Financial Statements

At the date of modification, TDRs are initially classified as nonaccrual TDRs. TDR loans are returned to accruing status when there is economic substance to the restructuring, there is documented credit evaluation of the borrower's financial condition, the remaining balance is reasonably assured of repayment in accordance with its modified terms, and the borrower has demonstrated sustained repayment performance in accordance with the modified terms for a reasonable period of time (generally a minimum of six months).

TDRs included in impaired loans at September 30, 2021 and December 31, 2020 had a combined balance of $707,000 and $315,000, respectively, and the Company had no commitments at these dates to lend additional funds on these loans. There was one new TDR modified during the nine months ended September 30, 2021 and no TDRs in default at that date. There were no new TDRs modified during the nine months ended September 30, 2020 and no TDRs in default at that date. The Bank considers any loan 30 days or more past due to be in default.

Our policy with respect to accrual of interest on loans restructured as 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 probable. 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, then that loan is automatically placed on nonaccrual status.  The Company's policy with respect to nonperforming loans requires the borrower to make a minimum of six consecutive payments in accordance with the modified loan terms before that loan can be placed back on accrual status.  Further, the borrower must demonstrate the capacity to continue making payments on the loan prior to restoration of accrual status.

The CARES Act amended GAAP with respect to the modification of loans to borrowers affected by the COVID-19 pandemic. Among other criteria, this guidance provided that short-term loan modifications made on a good faith basis to borrowers who were current as defined under the CARES Act prior to any relief, are not TDRs. This includes short-term (e.g. six months) modifications such as payment deferrals, fee waivers, extensions of repayment terms, or other delays in payment that are insignificant. To qualify as an eligible loan under the CARES Act, a loan modification must be 1) related to COVID-19; 2) executed on a loan that was not more than 30 days past due as of December 31, 2019; and 3) executed between March 1, 2020, and the earlier of a) 60 days after the date of termination of the national emergency by the President or b) December 31, 2020. The CAA, 2021 provides additional COVID-19 emergency response and relief, including extending relief offered under the CARES Act related to TDRs as a result of COVID-19 through January 1, 2022 or 60 days after the end of the national emergency declared by the President, whichever is earlier.

On April 7, 2020, the federal banking regulators issued a revised interagency statement on loan modifications and the reporting for financial institutions working with customers affected by the COVID-19 pandemic ("Interagency Statement"). The Interagency Statement confirmed that COVID-19 related short-term loan modifications (e.g., payment deferrals of six months or less) provided to borrowers that were current (less than 30 days past due) at the time the relief was granted are not TDR loans. Borrowers that do not meet the criteria in the CARES Act or the Interagency Statement are assessed for TDR loan classification in accordance with the Company’s accounting policies. All loans modified due to COVID-19 are separately monitored and any request for continuation of relief beyond the initial modification will be reassessed at that time to determine if a further modification should be granted and if a downgrade in risk rating is appropriate. Loan modifications in accordance with the CARES Act and related banking agency regulatory guidance are still subject to an evaluation in regards to determining whether or not a loan is deemed to be impaired. As of September 30, 2021, there were no loans still on deferral. At December 31, 2020, there were eight loans on deferral with a combined balance of $3.0 million.

9. Regulatory Matters

The Bank, as a state-chartered, federally insured savings bank, is subject to the capital requirements established by the FDIC. Under the FDIC's capital adequacy guidelines and the regulatory framework for prompt corrective action, the Bank must meet specific capital guidelines that involve quantitative measures of the Bank's assets, liabilities and certain off-balance-sheet items as calculated under regulatory accounting practices. The Bank's capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weighting and other factors.

The Company is a bank holding company registered with the Federal Reserve. Bank holding companies are subject to capital adequacy requirements of the Federal Reserve under the Bank Holding Company Act of 1956, as amended, and the regulations of the Federal Reserve. For a bank holding company with less than $3.0 billion in assets, the capital guidelines apply on a bank only basis and the Federal Reserve expects the holding company's subsidiary banks to be well-capitalized under the prompt corrective action regulations. If Security Federal Corporation was subject to regulatory guidelines for bank holding companies with $3.0 billion or more in assets, it would have exceeded all regulatory capital requirements with Common Equity Tier 1 ("CET1") capital, Tier 1 leverage-based capital, Tier 1 risk-based capital and total risk-based capital ratios of 16.6%, 9.0%, 16.6% and 22.5%, respectively, at September 30, 2021.

Based on its capital levels at September 30, 2021, the Bank exceeded all regulatory capital requirements as of that date. Consistent with the Bank's goals to operate a sound and profitable organization, it is the Bank's policy to maintain a "well-capitalized" status under the regulatory capital categories of the FDIC. Based on capital levels at September 30, 2021, the Bank was considered to be "well-capitalized" under applicable regulatory requirements. Management monitors the capital levels to provide for current and future business opportunities and to maintain the Bank's "well-capitalized" status.

The tables below provide the Bank’s regulatory capital requirements and actual results at the dates indicated.

	Actual			For Capital Adequacy			To Be "Well-Capitalized"
	Amount		Ratio	Amount		Ratio	Amount		Ratio
September 30, 2021	Dollars in Thousands
Tier 1 Risk-Based Core Capital (To Risk Weighted Assets)	$	121,421	18.8%	$	38,751	6.0%	$	51,669	8.0%
Total Risk-Based Capital (To Risk Weighted Assets)	129,532		20.1%	51,669		8.0%	64,586		10.0%
Common Equity Tier 1 Capital (To Risk Weighted Assets)	121,421		18.8%	29,064		4.5%	41,981		6.5%
Tier 1 Leverage (Core) Capital (To Adjusted Tangible Assets)	121,421		10.2%	47,625		4.0%	59,531		5.0%
December 31, 2020
Tier 1 Risk-Based Core Capital (To Risk Weighted Assets)	$	109,673	18.6%	$	35,330	6.0%	$	47,107	8.0%
Total Risk-Based Capital (To Risk Weighted Assets)	117,101		19.9%	47,107		8.0%	58,884		10.0%
Common Equity Tier 1 Capital (To Risk Weighted Assets)	109,673		18.6%	26,498		4.5%	38,275		6.5%
Tier 1 Leverage (Core) Capital (To Adjusted Tangible Assets)	109,673		9.8%	44,957		4.0%	56,197		5.0%

In addition to the minimum capital requirements, the Bank must maintain a capital conservation buffer, which consists of additional CET1 capital greater than 2.5% of risk weighted assets above the required minimum levels in order to avoid limitations on paying dividends, repurchasing shares, and paying discretionary bonuses. At September 30, 2021 the Bank’s conservation buffer was 12.1%.

10. Carrying Amounts and Fair Value of Financial Instruments

GAAP requires the Company to disclose fair value of financial instruments measured at amortized cost on the balance sheet and to measure that fair value using an exit price notion, the price that would be received for an asset or paid to transfer a liability, in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date under current market conditions.

Accounting guidance emphasizes that fair value is a market-based measurement, not an entity-specific measurement. Therefore, a fair value measurement should be determined based on the assumptions that market participants would use in pricing the asset or liability. As a basis for considering market participant assumptions in fair value measurements, the guidance establishes a fair value hierarchy that distinguishes between market participant assumptions based on market data obtained from sources independent of the reporting entity (observable inputs that are classified within Levels 1 and 2 of the hierarchy) and the reporting entity’s own assumptions about market participant assumptions (unobservable inputs classified within Level 3 of the hierarchy). The following three levels of inputs may be used to measure fair value:

Level 1 -	Quoted Market Price in Active Markets Valuation is based upon quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access. Level 1 assets and liabilities include debt and equity securities and derivative contracts that are traded in an active exchange market, as well as U.S. Treasuries and money market funds.
Level 2 -	Significant Other Observable Inputs Valuation is based upon quoted prices for similar assets and liabilities in active markets, as well as inputs that are observable for the asset or liability (other than quoted prices), such as interest rates, foreign exchange rates, and yield curves that are observable at commonly quoted intervals. Level 2 assets and liabilities include debt securities with quoted prices that are traded less frequently than exchange-traded instruments, mortgage-backed securities, municipal bonds, corporate debt securities and derivative contracts whose value is determined using a pricing model with inputs that are observable in the market or can be derived principally from or corroborated by observable market data. This category generally includes certain derivative contracts.
Level 3 -	Significant Unobservable Inputs Valuation is generated from model-based techniques that use at least one significant assumption based on unobservable inputs for the asset or liability, which are typically based on an entity’s own assumptions, as there is little, if any, related market activity. In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. The assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the asset or liability.

The following is a description of the valuation methodologies used for assets and liabilities recorded at fair value.

Investment Securities Available for Sale

Investment securities available for sale are recorded at fair value on a recurring basis. At September 30, 2021, the Company’s investment portfolio was comprised of student loan pools, government and agency bonds, mortgage-backed securities issued by government agencies or GSEs, private label CMO mortgage-backed securities and municipal securities. Fair value measurement is based upon prices obtained from third party pricing services that use independent pricing models which rely on a variety of factors including reported trades, broker/dealer quotes, benchmark yields, economic and industry events and other relevant market information. As a result, these securities are classified as Level 2.

Mortgage Loans Held for Sale

The Company originates fixed rate residential loans on a servicing released basis in the secondary market. Loans closed but not yet settled with the FHLMC or other investors, are carried in the Company’s loans held for sale portfolio.  These loans are fixed rate residential loans that have been originated in the Company’s name and have closed.  Virtually all of these loans have commitments to be purchased by investors and the majority of these loans were locked in by price with the investors on the same day or shortly thereafter that the loan was locked in with the Company’s customers.  Therefore, these loans present very little market risk for the Company. The Company usually delivers a commitment to, and receives funding from, the investor within 30 days.  Commitments to sell these loans to the investor are considered derivative contracts and are sold to investors on a “best efforts" basis. The Company is not obligated to deliver a loan or pay a penalty if a loan is not delivered to the investor. As a result of the short-term nature of these derivative contracts, the fair value of the mortgage loans held for sale in most cases is the same as the value of the loan amount at its origination. These loans are classified as Level 2.

Impaired Loans

The Company does not record loans held for investment at fair value on a recurring basis. However, from time to time, a loan is considered impaired and an allowance for loan losses is established as necessary. Loans for which it is probable that payment of interest and principal will not be made in accordance with the contractual terms of the loan agreement are considered impaired. Once a loan is identified as impaired, management measures the impairment by determining the fair value of the collateral for the loan.

Fair value is estimated using one of the following methods: fair value of the collateral less estimated costs to sell, discounted cash flows, or market value of the loan based on similar debt. The fair value of the collateral less estimated costs to sell is the most frequently used method. Typically, the Company reviews the most recent appraisal and if it is over 24 months old will request a new third party appraisal. Depending on the particular circumstances surrounding the loan, including the location of the collateral, the date of the most recent appraisal and the value of the collateral relative to the recorded investment in the loan, management may order an independent appraisal immediately or, in some instances, may elect to perform an internal analysis. Specifically as an example, in situations where the collateral on a nonperforming commercial real estate loan is out of the Company’s primary market area, management would typically order an independent appraisal immediately, at the earlier of the date the loan becomes nonperforming or immediately following the determination that the loan is impaired. However, as a second example, on a nonperforming commercial real estate loan where management is familiar with the property and surrounding areas and where the original appraisal value far exceeds the recorded investment in the loan, management may perform an internal analysis whereby the previous appraisal value would be reviewed and adjusted for current conditions including recent sales of similar properties in the area and any other relevant economic trends. These valuations are reviewed at a minimum on a quarterly basis.

Those impaired loans not requiring an allowance represent loans for which the fair value of the expected repayments or collateral exceed the recorded investments in such loans. At September 30, 2021, our impaired loans were generally evaluated based on the fair value of the collateral. Impaired loans where an allowance is established based on the fair value of collateral require classification in the fair value hierarchy. The Company records impaired loans as nonrecurring Level 3. At September 30, 2021 and December 31, 2020, the recorded investment in impaired loans was $2.5 million and $2.2 million, respectively.

Foreclosed Assets

Foreclosed assets are adjusted to fair value upon transfer of the loans to foreclosed assets. Subsequently, foreclosed assets are carried at the lower of carrying value or fair value. Fair value is based upon independent market prices, appraised values of the collateral or management’s estimation of the value of the collateral. Foreclosed assets are recorded as nonrecurring Level 3.

Assets measured at fair value on a recurring basis were as follows at September 30, 2021 and December 31, 2020:

These include assets that are measured at the lower of cost or market that were recognized at fair value below cost at the end of the period. The tables below present assets measured at fair value on a nonrecurring basis at September 30, 2021 and December 31, 2020, aggregated by the level in the fair value hierarchy within which those measurements fall.

(1) Reported net of specific reserves. There were no specific reserves at September 30, 2021 and December 31, 2020.

There were no liabilities measured at fair value on a nonrecurring basis at September 30, 2021 or December 31, 2020.

For Level 3 assets and liabilities measured at fair value on a recurring or non-recurring basis at September 30, 2021 and December 31, 2020, the significant unobservable inputs used in the fair value measurements were as follows:

	Valuation	Significant	9/30/2021	12/31/2020
Level 3 Assets	Technique	Unobservable Inputs	Range of Inputs	Range of Inputs
Collateral Dependent Impaired Loans	Appraised Value/ Discounted Cash Flows	Discounts to appraised values or cash flows for estimated holding and/or selling costs or age of appraisal	—% - 14%	—% - 14%
Foreclosed Assets	Appraised Value/Comparable Sales	Discounts to appraised values for estimated holding or selling costs	30%	11% - 72%

For assets and liabilities not presented on the balance sheet at fair value, the following methods are used to determine fair value:

Cash and Cash Equivalents—The carrying amount of these financial instruments approximates fair value. All mature within 90 days and do not present unanticipated credit concerns.

Certificates of Deposit with Other Banks—Fair value is based on market prices for similar assets.

Investment Securities Held to Maturity—Securities held to maturity are valued at quoted market prices or dealer quotes.

Loans Receivable, Net—The fair value of loans is estimated using an exit price notion. The exit price notion uses a discounted cash flows technique to calculate the present value of expected future cash flows for a financial instrument and also incorporates other factors, such as enhanced credit risk, illiquidity risk and market factors that sometimes exist in exit prices in dislocated markets. The credit risk assumption is intended to approximate the fair value that a market participant would realize in a hypothetical orderly transaction. The Company’s loan portfolio is initially fair valued using a segmented approach. The Company divides its loan portfolio into the following categories: commercial real estate, other commercial, residential real estate, consumer and all other loans. The results are then adjusted to account for credit risk as described above.

A further credit risk discount must be applied through the use of a discounted cash flow model to compensate for illiquidity risk, based on certain assumptions included within the discounted cash flow model, primarily the use of discount rates that better capture inherent credit risk over the lifetime of a loan. This consideration of enhanced credit risk provides an estimated exit price for the Company’s loan portfolio. For variable-rate loans that reprice frequently and have no significant change in credit risk, fair values approximate carrying values.

FHLB Stock—The fair value approximates the carrying value.

Deposits—The fair value of demand deposits, savings accounts, and money market accounts is the amount payable on demand at the reporting date. The fair value of fixed-maturity certificates of deposits is estimated by discounting the future cash flows using rates currently offered for deposits of similar remaining maturities.

FHLB Advances and Borrowings from the FRB—Fair value is estimated using discounted cash flows with current market rates for borrowings with similar terms.

Other Borrowed Money—The carrying value of these short term borrowings approximates fair value.

Subordinated Debentures—The fair value is estimated by discounting the future cash flows using the current rates at which similar debenture offerings with similar terms and maturities would be issued by similar institutions. As discount rates are based on current debenture rates as well as management estimates, the fair values presented may not be indicative of the value negotiated in an actual sale.

Junior Subordinated Debentures—The carrying value of junior subordinated debentures approximates fair value.

The following tables provide a summary of the carrying value and estimated fair value of the Company’s financial instruments at September 30, 2021 and December 31, 2020 presented in accordance with the applicable accounting guidance.

At September 30, 2021, the Bank had $175.5 million in off-balance sheet financial commitments.  These commitments are to originate loans and unused consumer lines of credit and credit card lines.  Because these obligations are based on current market rates, if funded, the original principal amount is considered to be a reasonable estimate of fair value. Fair value estimates are made on a specific date, based on relevant market data and information about the financial instrument.  These estimates do not reflect any premium or discount that could result from offering for sale the Bank’s entire holdings of a particular financial instrument.

Because no active market exists for a significant portion of the Bank’s financial instruments, fair value estimates are based on judgments regarding future expected loss experience, current economic conditions, current interest rates and prepayment trends, risk characteristics of various financial instruments, and other factors.  These estimates are subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision.  Changes in any of these assumptions used in calculating fair value would also significantly affect the estimates. Fair value estimates are based on existing on- and off-balance sheet financial instruments without attempting to estimate the value of anticipated future business and the value of assets and liabilities that are not considered financial instruments.  For example, the Bank has significant assets and liabilities that are not considered financial assets or liabilities including deposit franchise values, loan servicing portfolios, deferred tax liabilities, and premises and equipment.

In addition, the tax ramifications related to the realization of the unrealized gains and losses can have a significant effect on fair value estimates and have not been considered in any of these estimates. The Company has used management’s best estimate of fair value on the above assumptions.  Thus, the fair values presented may not be the amounts, which could be realized, in an immediate sale or settlement of the instrument.  In addition, any income taxes or other expenses that would be incurred in an actual sale or settlement are not taken into consideration in the fair value presented.

11. Accounting and Reporting Changes

The following is a summary of recent authoritative pronouncements that could affect accounting, reporting, and disclosure of financial information by the Company:

In June 2016, the FASB issued guidance to change the accounting for credit losses and modify the impairment model for certain debt securities. The guidance significantly changes the impairment model for most financial assets that are measured at amortized cost and certain other instruments from an incurred loss model to an expected loss model. The amendments will be effective for the Company for reporting periods beginning after December 15, 2022. Early adoption is permitted. The Company is in the process of identifying required changes to the loan loss estimation models and processes and evaluating the impact of this new guidance. Once adopted, we expect our allowance for loan losses to increase, however, until our evaluation is complete the magnitude of the increase will be unknown.

In April 2019, the FASB issued guidance to provide entities that have certain financial instruments measured at amortized cost that have credit losses, to irrevocably elect the fair value option in Subtopic 825-10, upon adoption of the June 2016 guidance related to accounting for credit losses and modifying the impairment model for certain debt securities. The fair value option applies to available-for-sale debt securities. This guidance should be applied at adoption on a modified-retrospective basis as a cumulative-effect adjustment to the opening balance of retained earnings in the statement of financial condition. The Company does not expect the adoption of this guidance to have a material effect on its consolidated financial statements.

In December 2019, the FASB issued guidance simplifying the accounting for income taxes by removing certain exceptions to the general principles in Topic 740, Income Taxes. The amendments also improve consistent application or and simplify GAAP for other areas of Topic 740 by clarifying and amending existing guidance. This guidance became effective for reporting periods beginning after December 15, 2020. The adoption of these amendments did not have a material effect on the Company's consolidated financial statements.

In March 2020, the FASB issued guidance that applies to contracts, hedging relationships and other transactions that reference the London Interbank Offered Rate ("LIBOR") or other rate references expected to be discontinued because of reference rate reform. The guidance permits an entity to make necessary modifications to eligible contracts or transactions without requiring contract remeasurement or reassessment of a previous accounting determination. In January 2021, updated guidance was issued to clarify that certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting apply to derivative instruments that use an interest rate for margining, discounting, or contract price alignment that is modified as a result of reference rate reform. Amendments in this guidance to the expedients and exceptions in Topic 848 capture the incremental consequences of the scope clarification and tailor the existing guidance to derivative instruments affected by the discounting transition. The amendments in this guidance have differing effective dates, beginning with an interim period including and subsequent to March 12, 2020 through December 31, 2022. The Company does not expect adoption of this guidance to have a material impact on its consolidated financial statements.

In October 2020, the FASB issued guidance which clarifies that the Company should reevaluate whether a callable debt security is within the scope of paragraph 310-20-35-33 for each reporting period. This guidance became effective for reporting periods beginning after December 15, 2020. The adoption of this guidance did not have a material impact on the Company's consolidated financial statements.

Other accounting standards that have been issued or proposed by the FASB or other standards-setting authorities are not expected to have a material impact on the Company’s consolidated financial position, results of operations or cash flows.

12. Non-Interest Income

Revenue Recognition

In accordance with Topic 606, revenues are recognized when control of promised goods or services is transferred to customers in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. To determine revenue recognition for arrangements that an entity determines are within the scope of Topic 606, the Company performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the Company satisfies a performance obligation.

The Company only applies the five-step model to contracts when it is probable that the entity will collect the consideration it is entitled to in exchange for the goods or services it transfers to the customer. At contract inception, once the contract is determined to be within the scope of Topic 606, the Company assesses the goods or services that are promised within each contract and identifies those that contain performance obligations, and assesses whether each promised good or service is distinct. The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied.

Deposit Fees

The Bank earns fees from its deposit customers for account maintenance, transaction-based and overdraft services.  Account maintenance fees consist primarily of account fees and analyzed account fees charged on deposit accounts on a monthly basis.  The performance obligation is satisfied and the fees are recognized on a monthly basis as the service period is completed. Transaction-based fees on deposits accounts are charged to deposit customers for specific services provided to the customer, such as non-sufficient funds fees, overdraft fees, and wire fees. The performance obligation is completed as the transaction occurs and the fees are recognized at the time each specific service is provided to the customer.

Check Card Fee Income

Check card fee income represents fees earned when a debit card issued by the Bank is used.  The Bank earns interchange fees from debit cardholder transactions through the Mastercard payment network.  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. The performance obligation is satisfied and the fees are earned when the cost of the transaction is charged to the card.  Certain expenses directly associated with the debit card are recorded on a net basis with the fee income.

Trust Income

Trust income includes monthly advisory fees that are based on assets under management and certain transaction fees that are assessed and earned monthly, concurrently with the investment management services provided to the customer. The Bank does not charge performance based fees for its trust services and does not currently have any institutional clients, hedge funds or mutual funds. Although trust income is included within the scope of ASC 606, based on the fees charged by the Bank, there were no changes in the accounting for trust income.  

Gains/Losses on OREO Sales

Gains/losses on the sale of OREO are included in non-interest expense and are generally recognized when the performance obligation is complete. This is typically at delivery of control over the property to the buyer at the time of each real estate closing.

13. Leases     

Effective January 1, 2019 the Company adopted ASC 842 “Leases.” Currently, the Company has operating leases on six of its branches that are accounted for under this standard. As a result of this standard, the Company recognized a right-of-use asset of $3.1 million effective January 1, 2019. The Company entered into one of the six leases mentioned above on September 30, 2021 and recognized a right-of-use asset of $255,000 on that date. During the nine months ended September 30, 2021, the Company made cash payments in the amount of $325,000 for operating leases. The lease expense recognized during this period was $350,000 and the lease liability had a net increase of $16,000 due to the newly added lease. The weighted average lease term is 5.63 years and the weighted average discount rate used is 3.2%.

14. 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 estimates inherent in the process of preparing financial statements. Nonrecognized 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 has reviewed all events occurring through the date the consolidated financial statements were available to be issued and determined that there were no subsequent events requiring accrual or disclosure.

Forward-Looking Statements and “Safe Harbor” statement under the Private Securities Litigation Reform Act of 1995

Certain matters discussed in this Quarterly Report on Form 10-Q may constitute forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995.  These statements relate to our financial condition, results of operations, plans, objectives, future performance or business. Forward-looking statements are not statements of historical fact, are based on certain assumptions and are generally identified by use of the words "believes," "expects," "anticipates," "estimates," "forecasts," "intends," "plans," "targets," "potentially," "probably," "projects," "outlook" or similar expressions or future or conditional verbs such as "may," "will," "should," "would" and "could." Forward-looking statements include statements with respect to our beliefs, plans, objectives, goals, expectations, assumptions and statements about, among other things, expectations of the business environment in which we operate, projections of future performance or financial items, perceived opportunities in the market, potential future credit experience, and statements regarding our mission and vision. These forward-looking statements are based upon current management expectations and may, therefore, involve risk and uncertainties. Our actual results, performance, or achievements may differ materially from those suggested, expressed, or implied by forward-looking statements as a result of a wide variety or range of factors, including, but not limited to:

•the effect of the novel coronavirus of 2019 (“COVID-19”) pandemic, including on the Company’s credit quality and business operations, as well as its impact on general economic and financial market conditions and other uncertainties resulting from the COVID-19 pandemic, such as the extent and duration of the impact on public health, the U.S. and global economies, and consumer and corporate clients, including economic activity, employment levels and market liquidity;

•the credit risks of lending activities, including changes in the level and trend of loan delinquencies and write-offs and changes in our allowance for loan losses and provision for loan losses that may be affected by deterioration in the housing and commercial real estate markets which may lead to increased losses and non-performing assets in our loan portfolio, and may result in our allowance for loan losses not being adequate to cover actual losses, and require us to materially increase our allowance for loan losses;

•changes in general economic conditions, either nationally or in our market areas;

•changes in the levels of general interest rates, and the relative differences between short and long term interest rates, deposit interest rates, our net interest margin and funding sources;

Response to COVID-19

In March 2020, the outbreak of COVID-19 was recognized as a pandemic by the World Health Organization. The spread of COVID-19 has created a global public health crisis that has resulted in unprecedented uncertainty, volatility and disruption in financial markets and in governmental, commercial and consumer activity in the United States and globally, including the markets that we serve. Governmental responses to the pandemic have included orders to close businesses not deemed essential and directing individuals to restrict their movements, observe social distancing and shelter in place. These actions, together with responses to the pandemic by businesses and individuals, have resulted in rapid decreases in commercial and consumer activity, temporary, and some permanent, closures of many businesses that have led to a loss of revenues and a rapid increase in unemployment, material decreases in business valuations, disrupted global supply chains, market downturns and volatility, changes in consumer behavior related to pandemic fears, related emergency response legislation and an expectation that the Federal Reserve may maintain a low interest rate environment for the foreseeable future. Although financial markets have rebounded from significant declines that occurred earlier in the pandemic and U.S. and global economic conditions have shown signs of improvement since the beginning of the pandemic, many of the effects that arose or became more pronounced after the onset of the COVID-19 pandemic persisted this year. These changes have had and are likely to continue to have a significant adverse effect on the markets in which we conduct our business and the demand for our products and services.

In response to the current global situation surrounding the COVID-19 pandemic, the Bank has offered a variety of relief options designed to support our customers and the communities we serve.

Paycheck Protection Program ("PPP") Participation

During the nine months ended September 30, 2021, the Bank received $67.8 million in PPP loan repayments compared to $28.2 million during 2020. As a result of these repayments, the Bank recognized $4.5 million in deferred PPP loan fees which increased net interest income, $3.3 million of which was recognized during the nine months ended September 30, 2021.

At September 30, 2021, the Bank had $32.1 million in PPP loans remaining compared to $47.1 million at December 31, 2020. We expect that the great majority of our PPP loans will ultimately be forgiven by the SBA in accordance with the terms of the program. The balance of unamortized net deferred fees on PPP loans was $1.8 million at September 30, 2021 compared to $1.4 million at December 31, 2020.

Loan Modifications

Since March 31, 2020, the Bank approved modifications related to the COVID-19 pandemic on over 340 customer loans with a combined balance, net of deferred fees, of $114.9 million. The majority of these modifications were for commercial real estate loans. The primary method of relief was to allow the borrower a three to six month payment deferral. All of these deferrals have resumed regular principal and interest payments as of September 30, 2021.

Branch Operations and Additional Client Support

The impact of COVID-19 is rapidly evolving and its future social and economic effects are uncertain at this time. The actual impact will depend on many factors beyond our Company’s control; however, the Company is taking every step to protect the health and safety of its employees and customers. Many of our non-branch personnel are working remotely or have flexible work schedules, and we have established protective measures within our offices to help ensure the safety of those employees who must work on-site. The Families First Coronavirus Response Act, which requires certain employers to provide employees with paid sick leave or expanded family and medical leave for specified reasons related to COVID-19, also provides additional flexibility to our employees to help navigate their individual challenges.

Cash and cash equivalents decreased $4.5 million or 24.8% to $13.6 million at September 30, 2021 from $18.0 million at December 31, 2020 primarily due to a decrease in the Federal Reserve Outgoing Cash Letter account, which fluctuates daily. Investment and mortgage-backed securities AFS increased $38.5 million or 6.5% to $627.8 million at September 30, 2021 from $589.3 million at December 31, 2020 as purchases of new investments and mortgage-backed securities AFS exceeded maturities and principal paydowns during the nine months ended September 30, 2021. Investment and mortgage-backed securities HTM increased $4.2 million or 22.8% to $22.4 million at September 30, 2021 from $18.3 million at December 31, 2020 as a result of purchases during 2021.

Loans receivable, net, including loans held for sale, increased $21.4 million or 4.5% to $500.6 million at September 30, 2021 from $479.2 million at December 31, 2020, primarily due to commercial business and real estate loans originated during the period. Loan balances in the commercial business, commercial real estate and consumer loan categories all increased while residential real estate, loans held for sale and PPP loan balances all decreased since the prior year end. Commercial business loans increased $8.4 million or 42.4% to $28.1 million at September 30, 2021 from $19.7 million at December 31, 2020. Commercial real estate loans increased $38.1 million or 12.7% to $337.4 million at September 30, 2021 from $299.3 million at December 31, 2020. Consumer loans grew $259,000 or 0.5% to $55.6 million at September 30, 2021 from $55.3 million at December 31, 2020. Residential real estate loans decreased $1.5 million or 1.9% to $77.4 million at September 30, 2021 from $78.9 million at December 31, 2020. Loans held for sale, decreased $2.1 million or 37.0% to $3.6 million at September 30, 2021 from $5.7 million at December 31, 2020. PPP loans decreased $15.0 million or 31.8% to $32.1 million at September 30, 2021 from $47.1 million at December 31, 2020.

OREO decreased $369,000 or 73.9% to $130,000 at September 30, 2021 from $499,000 at December 31, 2020 due to a write-down of $20,000 combined with the sale of two OREO properties, with a combined book value of $349,000, during the nine months ended September 30, 2021. At September 30, 2021, OREO consisted of one commercial land property located in Aiken, South Carolina.

FHLB stock decreased $1.4 million or 59.1% to $1.0 million at September 30, 2021 from $2.4 million at December 31, 2020 as a result of a decrease in advances from the FHLB of Atlanta. The Bank, as a member of the FHLB of Atlanta, is required to acquire and hold shares of capital stock in the FHLB of Atlanta in an amount equal to a membership component, which is 0.09% of total assets, plus a transaction component, which is 4.25% of outstanding advances (borrowings) from the FHLB of Atlanta. As the Bank's total advances have decreased, so has its required investment in FHLB stock.

Deposit Accounts

Total deposits increased $98.5 million or 10.7% to $1.0 billion at September 30, 2021 from $918.1 million at December 31, 2020. This growth was primarily due to proceeds from PPP loans and government stimulus checks deposited directly into customer accounts, organic growth in customer relationships and reduced withdrawals from deposit accounts due to a change in spending habits as a result of the ongoing COVID-19 pandemic. The $123.5 million increase in demand accounts was partially offset by a $25.0 million decrease in certificate accounts during the first nine months of 2021. The balance, weighted average rates and increases and decreases in deposit accounts at September 30, 2021 and December 31, 2020 are shown below.

Total Advances	$	10,000	1.45	%	$	35,000	1.83	%	$	(25,000)	(71.4)%

Advances are secured by a blanket collateral agreement with the FHLB pledging the Bank’s portfolio of residential first mortgage loans and investment securities with an amortized cost and fair value of $97.0 million and $97.6 million, at September 30, 2021 and $104.7 million and $106.2 million at December 31, 2020, respectively.

There were no callable FHLB advances at September 30, 2021. Callable advances are callable at the option of the FHLB.  If an advance is called, the Bank has the option to pay off the advance without penalty, re-borrow funds on different terms, or convert the advance to a three-month floating rate advance tied to LIBOR.

Borrowings From the Federal Reserve Bank

At September 30, 2021, the Bank had $15.4 million in borrowings from the "discount window" of the Federal Reserve Bank of Atlanta compared to $48.7 million at December 31, 2020. Depository institutions may borrow from the discount window for periods as long as 90 days, and borrowings are prepayable and renewable by the borrower on a daily basis. Effective March 16, 2020 the borrowing rate was set at the top of the targeted Federal Funds Rate, or 0.25%.  At September 30, 2021, the collateral pledged by the Bank for these borrowings consisted of investment and mortgage-backed securities with an amortized cost and fair value of $80.9 million and $84.7 million, respectively.

Other Borrowings (Repurchase Agreements)

The Bank had $26.6 million in other borrowings at September 30, 2021, an increase of $13.5 million or 102.8% from $13.1 million at December 31, 2020. These borrowings consist of short-term repurchase agreements with certain commercial demand deposit customers for sweep accounts. The repurchase agreements typically mature within one to three days and the interest rate paid on these borrowings floats monthly with money market type rates. The interest rate paid on the repurchase agreements was 0.15% at both September 30, 2021 and December 31, 2020.

Collateral pledged by the Bank for these repurchase agreements consisted of investment and mortgage-backed securities with amortized costs and fair values of $38.1 million and $38.1 million at September 30, 2021 and $26.6 million and $26.8 million at December 31, 2020, respectively.

Junior Subordinated Debentures

In September 2006, Security Federal Statutory Trust (the "Trust"), issued and sold fixed and floating rate capital securities of the Trust (the “Capital Securities”). The Trust used the net proceeds from the sale of the Capital Securities to purchase a like amount of junior subordinated debentures (the “Debentures”) of the Company which are reported on the Consolidated Balance Sheets as junior subordinated debentures. The Capital Securities accrue and pay distributions at a floating rate of three month LIBOR plus 170 basis points annually which was equal to 1.82% at September 30, 2021 compared to 1.92% at December 31, 2020. The distribution rate payable on the Capital Securities is cumulative and payable quarterly in arrears. The Capital Securities mature or are mandatorily redeemable upon maturity on December 15, 2036, or upon earlier optional redemption as provided in the indenture. The Company has the right to redeem the Capital Securities in whole or in part.

Subordinated Debentures

In November 2019, the Company sold and issued to certain institutional investors $17.5 million in aggregate principal amount of 5.25% fixed-to-floating rate subordinated notes due 2029 (the “10-Year Notes”) and $12.5 million in aggregate principal amount of 5.25% fixed-to-floating rate subordinated notes due 2034 (the “15-Year Notes”, and together with the 10-Year Notes, the “Notes”).

The 10-Year Notes have a stated maturity of November 22, 2029, and bear interest at a fixed rate of 5.25% per year, from and including November 22, 2019 but excluding November 22, 2024. From and including November 22, 2024 to but excluding the maturity date or early redemption date, the interest rate shall reset semi-annually to an interest rate equal to the then-current three-month LIBOR rate plus 369 basis points.

The 15-Year Notes have a stated maturity of November 22, 2034, and bear interest at a fixed rate of 5.25% per year, from and including November 22, 2019 but excluding November 22, 2029. From and including November 22, 2029 to but excluding the maturity date or early redemption date, the interest rate for the 15-Year Notes shall reset semi-annually to an interest rate equal to the then-current three-month LIBOR rate plus 357 basis points. The Notes are payable semi-annually in arrears on June 1 and December 1 of each year commencing June 1, 2020.

The Notes are not subject to redemption at the option of the holder and may be redeemed by the Company only under certain limited circumstances prior to November 22, 2024, with respect to the 10-Year Notes, and November 22, 2029, with respect to the 15-Year Notes. The Company may redeem the 10-Year Notes and the 15-Year Notes at its option, in whole at any time, or in part from time to time, after November 22, 2024 and November 22, 2029, respectively. The Notes are unsecured, subordinated obligations of the Company and rank junior in right to payment to the Company’s current and future senior indebtedness, and each Note is equal in right to payment with respect to the other Notes. The Company used the net proceeds from the sale of the Notes to fund the redemption of the Convertible Debentures and for general corporate purposes.

Shareholders’ Equity

Shareholders’ equity increased $4.8 million or 4.3% to $116.7 million at September 30, 2021 from $111.9 million at December 31, 2020. The increase was primarily attributable to net income of $10.7 million, which was partially offset by a $4.9 million decrease in accumulated other comprehensive income, net of tax and $1.1 million in dividends paid to common shareholders during the nine months ended September 30, 2021. The decrease in net accumulated other comprehensive income was related to the unrecognized loss in value of investment and mortgage-backed securities during the nine months ended September 30, 2021. Book value per common share was $35.87 at September 30, 2021 compared to $34.40 at December 31, 2020.

Results of Operations for the Three Month Periods Ended September 30, 2021 and 2020

Net Income

Net income increased $3.7 million or 413.1% to $4.6 million or $1.43 per basic common share for the quarter ended September 30, 2021 compared to $905,000 or $0.28 per basic common share for the quarter ended September 30, 2020. The increase in net income was primarily the result of decreases in interest expense and the provision for loan losses combined with an increase in non-interest income during the third quarter of 2021.

Net Interest Income

Net interest income increased $916,000 or 11.6% to $8.8 million during the quarter ended September 30, 2021, compared to $7.9 million for the same period in 2020. During the quarter ended September 30, 2021, average interest-earning assets increased $89.0 million or 8.6% to $1.1 billion from $1.0 billion for the same period in 2020, while average interest-bearing liabilities increased $30.8 million or 3.7% to $866.6 million for the quarter ended September 30, 2021 from $835.8 million for the comparable period in 2020. The Company's net interest margin was 3.17% for the quarter ended September 30, 2021 compared to 3.09% for the comparable period in 2020. The Company's net interest spread on a tax equivalent basis was 3.08% for the quarter ended September 30, 2021 compared to 2.96% for the quarter ended September 30, 2020.

In response to COVID-19, the Federal Reserve reduced the targeted Federal Funds Rate by 150 basis points during March 2020 to a range of 0.00% to 0.25%, where it remains at September 30, 2021. The effect of changes in the targeted Federal Funds Rate on the cost of funding liabilities typically lags the effect on the yield earned on interest-earning assets because rates on many deposit accounts are based on local competition and not tied to a specific market-based index. Interest-earning assets adjust earlier because they are tied to a specific market-based index. Because the length of the COVID-19 pandemic and the effects of the extraordinary measures being put in place to address its economic consequences are unknown, until the pandemic subsides, the Company expects its net interest income and net interest margin will be adversely affected in 2021 and possibly longer.

Interest Income

The following table compares detailed average balances, associated yields, and the resulting changes in interest income for the three months ended September 30, 2021 and 2020:

(2) Tax equivalent basis recognizes the income tax savings when comparing taxable and tax-exempt assets and was calculated using an effective tax rate of 21% for the quarters ended September 30, 2021 and 2020. The tax equivalent adjustment relates to the tax exempt municipal bonds and was $68,478 and $61,425 for the quarters ended September 30, 2021 and 2020, respectively.

Average interest-earning assets increased $89.0 million, or 8.6%, and total tax equivalent interest income increased $337,000, or 3.6%, to $9.7 million for the quarter ended September 30, 2021 compared to the same period in 2020 despite a 17 basis point decline in the average yield on interest-earning assets.

Total interest income on loans increased $488,000 or 7.2% to $7.3 million for the quarter ended September 30, 2021 from $6.8 million for the third quarter of 2020. The increase in interest income from loans was the result of a 77 basis point increase in the average yield on loans receivable, which was primarily driven by the recognition of $1.5 million in fee income related to PPP loans during the quarter ended September 30, 2021. This increase was partially offset by a $39.3 million or 7.2% decrease in the average loan portfolio balance.

Interest income from MBS decreased $173,000 or 11.7% to $1.3 million during the quarter ended September 30, 2021 due to a 74 basis point decrease in the average yield, which was partially offset by a $62.8 million increase in the average balance of these assets. Tax equivalent interest income from investment securities decreased $22,000 or 1.9% to $1.2 million during the quarter ended September 30, 2021 due to a decrease of 37 basis points in the average yield on investment securities, partially offset by a $66.2 million or 26.9% increase in the average balance of the investment securities portfolio.

(2) Includes FHLB Advances, FRB Borrowings and Repurchase Agreements

Total interest expense decreased $586,000 or 41.0% to $845,000 for the quarter ended September 30, 2021 compared to $1.4 million for the same period in 2020 due to a decline of 29 basis points in the average cost of interest bearing liabilities, which was partially offset by a $30.8 million or 3.7% increase in the average balance of these liabilities.

The largest decrease in interest expense was related to deposits. Despite a $58.2 million increase in the average balance of deposit accounts, the average cost of interest-bearing deposits decreased 24 basis points, resulting in a $410,000 decrease in interest expense during the third quarter of 2021 when compared to the same quarter in 2020. Interest expense on certificate accounts had the largest decrease in interest expense due to a decrease of $53.6 million in the average balance combined with a 60 basis point decrease in the average cost of certificate deposits during the third quarter of 2021, as management elected to utilize liquidity gained from lower cost deposits to reduce its balances of higher cost certificates of deposit in a managed reduction of these funds. Interest expense on FHLB advances, FRB borrowings and repurchase agreements decreased $173,000 for the third quarter of 2021 due to a $27.4 million decrease in the average balance of these interest-bearing liabilities, combined with a decrease of 82 basis points in the average cost.

Provision for Loan Losses

The amount of the provision is determined by management’s on-going monthly analysis of the loan portfolio and the adequacy of the allowance for loan losses. The Company has policies and procedures in place for evaluating and monitoring the overall credit quality of the loan portfolio and for timely identification of potential problem loans including internal and external loan reviews. The adequacy of the allowance for loan losses is reviewed monthly by the Asset Classification Committee and quarterly by the Board of Directors. Management’s monthly review of the adequacy of the allowance includes three main components.

The first component is an analysis of loss potential in various homogeneous segments of the loan portfolio based on historical trends and the risk inherent in each loan category. Currently, management applies a ten year historical loss ratio to each loan category to estimate the inherent loss in these pooled loans.

Management's Discussion and Analysis of Financial Condition and Results of Operations

The second component of management’s monthly analysis is the specific review and evaluation of significant problem credits identified through the Company’s internal monitoring system. These loans are evaluated for impairment and recorded in accordance with accounting guidance. For each loan deemed impaired, management calculates a specific reserve for the amount in which the recorded investment in the loan exceeds the fair value. This estimate is based on a thorough analysis of the most probable source of repayment, which is typically liquidation of the collateral underlying the loan.

The third component is an analysis of changes in qualitative factors that may affect the portfolio, including but not limited to: relevant economic trends that could impact borrowers’ ability to repay, industry trends, changes in the volume and composition of the portfolio, credit concentrations, or lending policies and the experience and ability of the staff and Board of Directors.

Management also reviews and incorporates certain ratios such as percentage of classified loans, average historical loan losses by loan category, delinquency percentages, and the assignment of percentage targets of reserves in each loan category when evaluating the allowance. Once the analysis is completed, the three components are combined and compared to the allowance amount. Based on this, charges are made to the provision as needed. Because the SBA guarantees 100% of the PPP loans made to eligible borrowers, these loans do not have a corresponding allowance for loan loss.

The table below shows the changes in the allowance for loan losses for the quarters ended September 30, 2021 and 2020.

	Quarter Ended September 30,
(Dollars in thousands)	2021			2020
Beginning Balance	$	11,424		$	10,676

Gross Loans Receivable, Held For Investment (1)	$	508,184		$	533,221
Total Loans Receivable, Net	$	500,601		$	527,870
Allowance For Loan Losses as a % of Impaired Loans	449.8		%	399.3		%
Allowance For Loan Losses as a % of Gross Loans Receivable (1)	2.2		%	2.4		%
(1) TOTAL LOANS HELD FOR INVESTMENT, NET OF DEFERRED FEES AND LOANS IN PROCESS.

The Company had net recoveries of $413,000, or 0.33% of gross loans on an annualized basis, for the quarter ended September 30, 2021 compared to net charge-offs of $30,000, or 0.01% of gross loans on an annualized basis, for the third quarter of 2020. We had a negative provision for loan losses of $665,000 for the quarter ended September 30, 2021, compared to provision expense of $2.2 million for the third quarter of 2020. The negative provision for loan losses for the third quarter of 2021 resulted primarily from the net recoveries and a reduction in qualitative adjustment factors related to improvement in the economic and business conditions at both the national and regional levels as of September 30, 2021.

Our strategy is to work with our borrowers to reach acceptable payment plans while protecting our interests in the existing collateral. In the event an acceptable arrangement cannot be reached, we may need to acquire these properties through foreclosure or other means and subsequently sell, develop or liquidate them. Management believes the allowance for loan losses is adequate based on its best estimates of the probable losses inherent in the loan portfolio, although there can be no guarantee these estimates will not be proven incorrect in the future. In addition, bank regulatory agencies may require additional provisions to the allowance for loan losses based on their judgments and estimates as part of their examination process.  Because the allowance for loan losses is an estimate, there is no guarantee that actual loan losses will not exceed the allowance for loan losses, or that additional increases in the allowance for loan losses will not be required in the future. A decline in national and local economic conditions, as a result of the COVID-19 pandemic or other factors, could result in a material increase in the allowance for loan losses and may adversely affect the Company’s financial condition and results of operations.

The $1.5 million increase in non-interest income was primarily attributable to a $1.8 million grant received during the quarter ended September 30, 2021. The grant was awarded by the Community Development Financial Institutions (CDFI) Rapid Response Program (RRP) in order to provide certified CDFIs with resources to help counter the economic impact of COVID-19 in distressed and underserved communities. The grant proceeds were used to fund qualified loans within the Bank’s target market areas. The increase in grant income was partially offset by decreases in gain on sale of MBS and investment securities and gain on sale of loans during the quarter ended September 30, 2021. net gain on $139,000 Gain on sale of loans $252,000

Results of Operations for the Nine Months Ended September 30, 2021 and 2020

Net Income

Net income increased $6.8 million or 169.6% to $10.7 million for the nine months ended September 30, 2021 compared to the same nine month period in 2020. The increase in earnings was primarily the result of decreases in interest expense and the provision for loan losses combined with an increase in non-interest income during the first nine months of 2021 when compared to the same period last year.

Net Interest Income

Net interest income increased $2.5 million or 11.1% to $24.6 million for the nine months ended September 30, 2021 compared to $22.1 million for the same period last year. During the nine months ended September 30, 2021, average interest earning assets increased $117.6 million or 11.8% to $1.1 billion from $992.7 million for the nine months ended September 30, 2020. Average interest-bearing liabilities also increased by $41.8 million or 5.0% to $869.7 million for the nine months ended September 30, 2021 from $827.9 million for the same period in 2020. The Company's net interest margin fell two basis points to 2.98% for the nine months ended September 30, 2021 compared to 3.00% for the nine months ended September 30, 2020. The net interest spread on a tax equivalent basis grew three basis points to 2.88% for the nine months ended September 30, 2021 from 2.85% for the comparable period in 2020.

    (1) Annualized

(2) Tax equivalent basis recognizes the income tax savings when comparing taxable and tax-exempt assets and was calculated using an effective tax rate of 21% for the nine months ended September 30, 2021 and 2020. The tax equivalent adjustment relates to the tax exempt municipal bonds and was $201,978 and $190,996 for the nine months ended September 30, 2021 and 2020, respectively.

Total tax equivalent interest income decreased $39,000 to $27.7 million during the nine months ended September 30, 2021 compared to the first nine months of 2020, due to decreases in interest income from MBS, investment securities and other interest-earning assets, which were partially offset by an increase in interest income from loans. Total interest income on loans increased $706,000 or 3.7% to $20.0 million during the nine months ended September 30, 2021 from $19.3 million for the same period in 2020. The increase was a result of a 21 basis point increase in the average yield on loans receivable, which was primarily driven by the recognition of $3.3 million in fee income related to PPP loans during the nine months ended September 30, 2021. The increase was partially offset by a $2.9 million or 0.6% decrease in the average loan balance.

Interest income from MBS decreased $710,000 or 15.0% to $4.0 million for the nine months ended September 30, 2021 from $4.7 million for the same period in 2020. The decrease was the result of a 78 basis point decline in the average MBS portfolio yield, which was partially offset by a $50.7 million or 21.1% increase in the average balance of mortgage-backed securities. Tax equivalent interest income from investment securities increased $12,000 or 0.3% to $3.6 million for the nine months ended September 30, 2021 when compared to the same nine month period in 2020.

Interest expense decreased $2.5 million or 46.4% to $2.9 million during the nine months ended September 30, 2021 compared to $5.4 million for the same period in 2020. The decrease in total interest expense was attributable to a decrease of 43 basis points in the cost of interest-bearing liabilities, which was partially offset by a $41.8 million or 5.0% increase in the average balance of these liabilities.

Interest expense on FHLB advances and other borrowings decreased $311,000 or 44.5% to $389,000 during the nine months ended September 30, 2021 from $701,000 during the same period in 2020 due to a $19.6 million or 24.8% decrease in the average balance combined with a decline of 31 basis points in the average cost of these liabilities during the nine months ended September 30, 2021 when compared to the same period last year.

Provision for Loan Losses

There was $2.3 million in negative provision for loan losses recorded during the nine months ended September 30, 2021 compared to provision expense of $3.6 million for the same period in 2020 reflecting a decline in the probable loan losses due to the COVID-19 pandemic as the economic and business conditions at both the national and regional levels continued to improve as of September 30, 2021.

Total Non-Interest Income	$	9,990,763	$	8,590,128	$	1,400,635	16.3	%

The increase in non-interest income was primarily attributable to increases in gain on sale of loans, trust income, ATM & check card fee income and grant income reduced by the absence of gain on sale of MBS & investment securities during the nine months ended September 30, 2021. Gain on sale of loans increased $529,000 or 21.2% to $3.0 million for the nine months ended September 30, 2021 compared to $2.5 million during the same period in 2020 as the dollar volume of loans sold increased. ATM & Check Card Fee income increased $394,000 primarily due to an increase in debit card usage. Grant income increased as a result of the $1.8 million CDFI RRP award received during 2021. The grant proceeds were used by the Bank to fund qualified loans in the target market areas we serve.

Non-Interest Expense

For the nine months ended September 30, 2021, non-interest expense increased $784,000 or 3.5% to $23.1 million compared to $22.3 million for the same period in 2020. The table below summarizes the changes in the components of non-interest expense.

Depreciation and maintenance of equipment increased $228,000 or 10.7% primarily due to additional capital expenses related to our new e-branch as well as our newest branch in the metro Augusta, Georgia area, which is scheduled to open next year.

FDIC insurance premiums increased $147,000 primarily due to the use of remaining FDIC small bank credits by the Bank during 2020.

The Company had a net recovery of $116,000 from the operation of OREO properties during the nine months ended September 30, 2021 compared to a net recovery of $27,000 during the nine months ended September 30, 2020.

Debit card expense increased $95,000 to $859,000 for the nine months ended September 30, 2021 due to the replacement of all customer debit cards in 2021 because of the inclusion of a new chip within the cards.

Other non-interest expense increased during the nine months ended September 30, 2021 due to increased operations as branches re-opened during 2021 after being closed for the majority of 2020 as a result of the COVID-19 pandemic. As of May 2021, all branches have reopened and resumed normal business hours.

Provision For Income Taxes

The provision for income taxes increased $2.2 million or 269.5% to $3.0 million for the nine months ended September 30, 2021 from $810,000 for the same period in 2020 primarily due to higher pre-tax income in 2021 and purchased state tax credits in 2020. Income before taxes was $13.7 million and $4.8 million for the nine months ended September 30, 2021 and 2020, respectively. The Company’s combined federal and state effective income tax rate was 21.8% for the nine months ended September 30, 2021 compared to 16.9% for the same period in 2020.

Liquidity Commitments, Capital Resources, and Impact of Inflation and Changing Prices

Liquidity

The Company actively analyzes and manages the Bank’s liquidity with the objective of maintaining an adequate level of liquidity and to ensure the availability of sufficient cash flows to support loan growth, fund deposit withdrawals, fund operations, and satisfy other financial commitments. See the “Consolidated Statements of Cash Flows” contained in Item 1 – Financial Statements, herein.

The Bank's primary sources of funds include deposits, scheduled loan and investment and mortgage-backed securities repayments, including interest payments, maturities and sales of loans and investment and mortgage-backed securities, advances from the FHLB, and cash flow generated from operations.  The sources of funds, together with retained earnings and equity, are used to make loans, acquire investment securities and other assets, and fund continuing operations. While maturities and the scheduled amortization of loans are a predictable source of funds, deposit flows and mortgage repayments are greatly influenced by the level of interest rates, economic conditions, and competition. Management believes that the Company’s current liquidity position and its forecasted operating results are sufficient to fund all of its existing commitments.

During the nine months ended September 30, 2021 loan disbursements exceeded loan repayments resulting in a $21.4 million or 4.5% increase in total net loans receivable. Also during the nine months ended September 30, 2021, deposits increased $98.5 million or 10.7% and FHLB advances decreased $25.0 million. The Bank had $349.9 million in additional borrowing capacity at the FHLB at the end of the period. The Bank also has secured an $80.9 million discount window facility at the FRB, collateralized by investment securities with a fair market value of $84.7 million. At September 30, 2021, the Bank had $15.4 million in outstanding borrowings at the FRB. The Bank also had a $5.0 million unused Fed Funds facility with Pacific Coast Bankers Bank at September 30, 2021. At September 30, 2021, the Bank had $114.3 million of certificates of deposit maturing within one year. Based on previous experience, the Bank anticipates a significant portion of these certificates will be renewed on maturity.

Management's Discussion and Analysis of Financial Condition and Results of Operations

At September 30, 2021, the Bank exceeded all regulatory capital requirements with Common Equity Tier 1 Capital (CET1), Tier 1 leverage-based capital, Tier 1 risk-based capital, and total risk-based capital ratios of 18.8%, 10.2%, 18.8%, and 20.1%, respectively. To be categorized as “well capitalized” under the prompt corrective action provisions the Bank must maintain minimum CET1, total risk based capital, Tier 1 risk-based capital and Tier 1 leverage capital ratios of 6.5%, 10.0%, 8.0% and 5.0%, respectively. In addition to the minimum capital requirements, the Bank must maintain a capital conservation buffer, which consists of additional CET1 capital greater than 2.5% of risk weighted assets above the required minimum levels in order to avoid limitations on paying dividends, repurchasing shares, and paying discretionary bonuses. At September 30, 2021 the Bank’s conservation buffer was 12.1%. For additional details, see “Footnote – Regulatory Matters” of the Notes to Consolidated Financial Statements included in Part I. Item 1 of this report.

Off-Balance Sheet Commitments

The Company is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments generally include commitments to originate mortgage, commercial and consumer loans, and involve to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the balance sheet. The Company’s maximum exposure to credit loss in the event of nonperformance by the borrower is represented by the contractual amount of those instruments. Since some commitments may expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Company uses the same credit policies in making commitments as it does for on-balance sheet instruments. Collateral is not required to support commitments.

The following table sets forth the length of time until maturity for unused commitments to extend credit and standby letters of credit at September 30, 2021.

(Dollars in thousands)	One Month or Less		After One Through Three Months		After Three Through Twelve Months		Total Within One Year		Greater Than One Year		Total
Unused Lines of Credit	$	1,776	$	3,383	$	57,660	$	62,819	$	110,292	$	173,111

Item 3. Quantitative and Qualitative Disclosures about Market Risk

Market risk is the risk of loss from adverse changes in market prices and rates. The Company’s market risk arises principally from interest rate risk inherent in its lending, investment, deposit and borrowing activities. Management actively monitors and manages its interest rate risk exposure. Although the Company manages other risks such as credit quality and liquidity risk in the normal course of business, management considers interest rate risk to be its most significant market risk that could potentially have the largest material effect on the Company’s financial condition and results of operations. Other types of market risks such as foreign currency exchange rate risk and commodity price do not arise in the normal course of the Company’s business activities.

The Company’s profitability is affected by fluctuations in the market interest rate. Management’s goal is to maintain a reasonable balance between exposure to interest rate fluctuations and earnings. A sudden and substantial increase or decrease in interest rates may adversely impact the Company’s earnings to the extent that the interest rates on interest-earning assets and interest-bearing liabilities do not change at the same rate, to the same extent or on the same basis. The Company monitors the impact of changes in interest rates on its net interest income using a test that measures the impact on net interest income and net portfolio value of an immediate change in interest rates in 100 basis point increments. Net portfolio value is defined as the net present value of assets, liabilities, and off-balance sheet contracts. There were no material changes in information concerning market risk from the information provided in the Company’s 2020 Form 10-K.

For the nine months ended September 30, 2021, the Bank's interest rate spread, defined as the average yield on interest bearing assets less the average rate paid on interest bearing liabilities was 2.88%.

Item 4. Controls and Procedures

(a) Evaluation of Disclosure Controls and Procedures: An evaluation of the Company’s disclosure controls and procedures (as defined in Rule 13a - 15(e) of the Securities Exchange Act of 1934 (“Act”)) was carried out under the supervision and with the participation of the Company’s Chief Executive Officer, Chief Financial Officer and several other members of the Company’s senior management as of the end of the period covered by this quarterly report. The Company’s Chief Executive Officer and Chief Financial Officer concluded that at September 30, 2021 the Company’s disclosure controls and procedures were effective in ensuring that the information required to be disclosed by the Company in the reports it files or submits under the Act is (i) accumulated and communicated to the Company’s management (including the Chief Executive Officer and Chief Financial Officer) in a timely manner, and (ii) recorded, processed, summarized and reported within the time period specified in the Securities and Exchange Commission’s rules and forms. There have been no significant changes in our internal controls over financial reporting during the quarter ended September 30, 2021 that have materially affected or are reasonably likely to affect our internal controls over financial reporting.

The Company does not expect that its disclosure controls and procedures will prevent all error and or fraud. A control procedure, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control procedure are met. Because of the inherent limitations in all control procedures, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of a simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the control. The design of any control procedure also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, controls may become inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control procedure, misstatements due to error or fraud may occur and not be detected.

Accounting Policies [Abstract]

Critical Accounting Policies

Critical Accounting Policies

The Company has adopted various accounting policies, which govern the application of accounting principles generally accepted in the United States in the preparation of our financial statements. Our significant accounting policies are described in the footnotes to the audited consolidated financial statements at December 31, 2020 included in our 2020 Annual Report to Shareholders. Certain accounting policies involve significant judgments and assumptions by management, which have a material impact on the carrying value of certain assets and liabilities, and, as such, have a greater possibility of producing results that could be materially different than originally reported. We consider these accounting policies to be critical accounting policies.  The judgments and assumptions we use are based on historical experience and other factors, which we believe to be reasonable under the circumstances.  Because of the nature of the judgments and assumptions we make, actual results could differ from these judgments and estimates which could have a material impact on our carrying values of assets and liabilities and our results of operations.

The Company believes the allowance for loan losses is a critical accounting policy that requires the most significant judgments and estimates used in preparation of the consolidated financial statements.  The impact of an unexpected and sudden large loss could deplete the allowance and potentially require increased provisions to replenish the allowance, which would negatively affect earnings. The Company provides for loan losses using the allowance method.  Accordingly, all loan losses are charged to the related allowance and all recoveries are credited to the allowance for loan losses.  Additions to the allowance for loan losses are provided by charges to operations based on various factors, which, in management’s judgment, deserve current recognition in estimating possible losses.  Such factors considered by management include the fair value of the underlying collateral, stated guarantees by the borrower (if applicable), the borrower’s ability to repay from other economic resources, growth and composition of the loan portfolio, the relationship of the allowance for loan losses to the outstanding loans, loss experience, delinquency trends, and general economic conditions.  Management evaluates the carrying value of the loans periodically and the allowance is adjusted accordingly.

3. Critical Accounting Policies, Continued

While management uses the best information available to make evaluations, future adjustments may be necessary if economic conditions differ substantially from the assumptions used in making these evaluations.  The allowance for loan losses is subject to periodic evaluations by our bank regulatory agencies, including the Board of Governors of the Federal Reserve System ("Federal Reserve"), the FDIC and the South Carolina Board of Financial Institutions, which may require adjustments to be made to the allowance based upon the information that is available at the time of their examination.

The Company values impaired loans at the loan’s fair value if it is probable that the Company will be unable to collect all amounts due according to the terms of the loan agreement at the present value of expected cash flows, the market price of the loan, if available, or the value of the underlying collateral.  Expected cash flows are required to be discounted at the loan’s effective interest rate.  When the ultimate collectibility of an impaired loan’s principal is in doubt, wholly or partially, all cash receipts are applied to principal.  When this doubt does not exist, cash receipts are applied under the contractual terms of the loan agreement first to interest and then to principal.  Once the recorded principal balance has been reduced to zero, future cash receipts are applied to interest income to the extent that any interest has been foregone.  Further cash receipts are recorded as recoveries of any amounts previously charged off.

The Company uses assumptions and estimates in determining income taxes payable or refundable for the current year, deferred income tax liabilities and assets for events recognized differently in its financial statements and income tax returns, and income tax expense. Determining these amounts requires analysis of certain transactions and interpretation of tax laws and regulations. The Company exercises considerable judgment in evaluating the amount and timing of recognition of the resulting tax liabilities and assets. These judgments and estimates are reevaluated on a continual basis as regulatory and business factors change. No assurance can be given that either the tax returns submitted by us or the income tax reported on the consolidated financial statements will not be adjusted by either adverse rulings by the United States Tax Court, changes in the tax code, or assessments made by the Internal Revenue Service.

Earnings Per Share [Abstract]

Earnings Per Share [Text Block]

Earnings Per Share

Accounting guidance specifies the computation, presentation and disclosure requirements for earnings per share (“EPS”) for entities with publicly held common stock or potential common stock such as options, warrants, convertible securities or contingent stock agreements if those securities trade in a public market. Basic EPS is computed by dividing net income by the weighted average number of common shares outstanding.  Diluted EPS is similar to the computation of basic EPS except that the denominator is increased to include the number of additional common shares that would have been outstanding if the dilutive common shares had been issued.  The dilutive effect of options outstanding under the Company’s stock option plan is reflected in diluted EPS by application of the treasury stock method. There were no stock options outstanding at September 30, 2021 or 2020; and therefore, no dilutive options were included in the calculation of diluted EPS for those periods. The following tables include a summary of the Company's basic EPS for three and nine months ended September 30, 2021 and 2020.

Student Loan Pools are typically 97% guaranteed by the United States government while SBA bonds are 100% backed by the full faith and credit of the United States government. The majority of the mortgage-backed securities included in the tables above and below are issued or guaranteed by an agency of the United States government such as Ginnie Mae, or by Government Sponsered Entities ("GSEs"), including Fannie Mae and Freddie Mac. Ginnie Mae mortgage-backed securities are backed by the full faith and credit of the United States government, while those issued by GSEs are not.

At September 30, 2021, AFS Ginnie Mae mortgage-backed securities had an amortized cost and fair value of $133.8 million and $133.9 million, respectively, compared to an amortized cost and fair value of $91.7 million and $93.4 million, respectively, at December 31, 2020.

Also included in mortgage-backed securities in the tables above and below are private label collateralized mortgage obligation ("CMO") securities, which are issued by non-governmental real estate mortgage investment conduits and are not backed by the full faith and credit of the United States government.  At September 30, 2021 the Bank held AFS private label CMO mortgage-backed securities with an amortized cost and fair value of $31.4 million and $31.6 million, compared to an amortized cost and fair value of $37.0 million and $37.7 million at December 31, 2020, respectively.

Securities classified as available for sale are recorded at fair market value.  At September 30, 2021 and December 31, 2020, 22.7% and 37.0% of the unrealized losses, representing 71 and 88 individual securities, respectively, consisted of securities in a continuous loss position for 12 months or more. The Company has the ability and intent to hold these securities until such time as the value recovers or the securities mature.  The Company believes, based on industry analyst reports and credit ratings, that the deterioration in value is attributable to changes in market interest rates and is not in the credit quality of the issuer and therefore, these losses are not considered other-than-temporary. The Company reviews its investment securities portfolio at least quarterly and more frequently when economic conditions warrant, assessing whether there is any indication of other-than-temporary impairment (“OTTI”).

Additional deterioration in market and economic conditions related to the novel coronavirus of 2019 (“COVID-19”) pandemic may, however, have an adverse impact on credit quality in the future and result in OTTI charges. Factors considered in the review include estimated future cash flows, length of time and extent to which market value has been less than cost, the financial condition and near term prospects of the issuer, and our intent and ability to retain the security to allow for an anticipated recovery in market value. If the review determines that there is OTTI, an impairment loss is recognized in earnings equal to the difference between the investment’s cost and its fair value at the balance sheet date of the reporting period for which the assessment is made, or the Company may recognize a portion in other comprehensive income. The fair value of investments on which OTTI is recognized then becomes the new cost basis of the investment. There was no OTTI recognized during the nine months ended September 30, 2021 and the year ended December 31, 2020.

During the year ended December 31, 2020, the Bank participated in the initial SBA Paycheck Protection Program (“PPP”), a guaranteed unsecured loan program enacted under the Coronavirus Aid, Relief and Economic Security Act of 2020 (“CARES Act”) signed into law on March 27, 2020 to provide near-term relief to help small businesses impacted by COVID-19 sustain operations. PPP loans are fully guaranteed by the SBA. Loan originations under the initial PPP ended in August 2020. The Consolidated Appropriations Act, 2021 (“CAA 2021”) enacted on December 27, 2020, renewed and extended the PPP until May 31, 2021. As a result, in January 2021, the Bank began accepting and processing loan applications under this second PPP.

As of September 30, 2021, the Bank had originated nearly 2,800 PPP loans to new and existing customers, totaling approximately $127.6 million. The Bank earns 1% interest on PPP loans as well as a fee from the SBA to cover processing costs, which is amortized over the life of the loan. The maturity date of a PPP loan is either two or five years from the date of loan origination. As of September 30, 2021, we have recognized $4.5 million in PPP loans fees, including $3.3 million recognized in the nine months ended September 30, 2021. The balance of unamortized net deferred fees on PPP loans was $1.8 million at September 30, 2021 compared to $1.4 million at December 31, 2020. The Bank expects that the great majority of PPP borrowers will seek full or partial forgiveness of their loan obligations in accordance with the CARES Act. Because the SBA guarantees 100% of the PPP loans made to eligible borrowers, and the entire principal amount of these loans, including any accrued interest, is eligible to be forgiven and repaid by the SBA, PPP loans are excluded from our allowance for loan losses calculation. There were 696 PPP loans totaling $32.1 million in our loan portfolio at September 30, 2021.

The Company uses a risk based approach based on the following credit quality measures when analyzing the loan portfolio: pass, caution, special mention, and substandard. These indicators are used to rate the credit quality of loans for the purposes of determining the Company’s allowance for loan losses. Pass loans are loans that are performing and are deemed adequately protected by the net worth of the borrower or the underlying collateral value. These loans are considered to have the least amount of risk in terms of determining the allowance for loan losses. Loans that are graded as substandard are considered to have the most risk. These loans typically have an identified weakness or weaknesses and are inadequately protected by the net worth of the borrower or collateral value. All loans 90 days or more past due are automatically classified in this category. The caution and special mention categories fall in between the pass and substandard grades and consist of loans that do not currently expose the Company to sufficient risk to warrant adverse classification but possess weaknesses.

The tables below summarize the balance within each risk category by loan type, excluding loans held for sale, at September 30, 2021 and December 31, 2020.

At September 30, 2021 and December 31, 2020, the Company did not have any loans that were 90 days or more past due and still accruing interest. The Company's strategy is to work with its borrowers to reach acceptable payment plans while protecting its interests in the existing collateral.  In the event an acceptable arrangement cannot be reached, the Company may have to acquire these properties through foreclosure or other means and subsequently sell, develop, or liquidate them.

Loans for which it is probable that payment of interest and principal will not be made in accordance with the contractual terms of the loan agreement are considered impaired. Non-accrual commercial loans under $200,000 and non-accrual consumer loans under $100,000 are considered immaterial and are excluded from the impairment review. Once a loan is identified as individually impaired, management measures the impairment and records the loan at fair value. Fair value is estimated using one of the following methods: fair value of the collateral less estimated costs to sell, discounted cash flows, or market value of the loan based on similar debt. The fair value of the collateral less estimated costs to sell is the most frequently used method.

Typically, the Company reviews the most recent appraisal and, if it is over 24 months old, will request a new third party appraisal. Depending on the particular circumstances surrounding the loan, including the location of the collateral, the date of the most recent appraisal and the value of the collateral relative to the recorded investment in the loan, management may order an independent appraisal immediately or, in some instances, may elect to perform an internal analysis. The average balance of impaired loans was $2.5 million and $2.6 million for the three and nine months ended September 30, 2021, respectively, compared to $3.3 million and $3.7 million for the three and nine months ended September 30, 2020, respectively.

The following tables present information related to impaired loans by loan category at September 30, 2021 and December 31, 2020 and for the nine months ended September 30, 2021 and 2020. There was no allowance recorded related to any impaired loans at September 30, 2021 and December 31, 2020.

In the course of resolving delinquent loans, the Company may choose to restructure the contractual terms of certain loans. A troubled debt restructuring ("TDR") is a restructuring in which the Company, for economic or legal reasons related to a borrower’s financial difficulties, grants a concession to a borrower that it would not otherwise consider (Financial Accounting Standards Board ("FASB") Accounting Standards Codification (“ASC”) Topic 310-40).  The concessions granted on TDRs generally include terms to reduce the interest rate, extend the term of the debt obligation, or modify the payment structure on the debt obligation. The Company grants such concessions to reassess the borrower’s financial status and develop a plan for repayment.  

At the date of modification, TDRs are initially classified as nonaccrual TDRs. TDR loans are returned to accruing status when there is economic substance to the restructuring, there is documented credit evaluation of the borrower's financial condition, the remaining balance is reasonably assured of repayment in accordance with its modified terms, and the borrower has demonstrated sustained repayment performance in accordance with the modified terms for a reasonable period of time (generally a minimum of six months).

TDRs included in impaired loans at September 30, 2021 and December 31, 2020 had a combined balance of $707,000 and $315,000, respectively, and the Company had no commitments at these dates to lend additional funds on these loans. There was one new TDR modified during the nine months ended September 30, 2021 and no TDRs in default at that date. There were no new TDRs modified during the nine months ended September 30, 2020 and no TDRs in default at that date. The Bank considers any loan 30 days or more past due to be in default.

Our policy with respect to accrual of interest on loans restructured as 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 probable. 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, then that loan is automatically placed on nonaccrual status.  The Company's policy with respect to nonperforming loans requires the borrower to make a minimum of six consecutive payments in accordance with the modified loan terms before that loan can be placed back on accrual status.  Further, the borrower must demonstrate the capacity to continue making payments on the loan prior to restoration of accrual status.

The CARES Act amended GAAP with respect to the modification of loans to borrowers affected by the COVID-19 pandemic. Among other criteria, this guidance provided that short-term loan modifications made on a good faith basis to borrowers who were current as defined under the CARES Act prior to any relief, are not TDRs. This includes short-term (e.g. six months) modifications such as payment deferrals, fee waivers, extensions of repayment terms, or other delays in payment that are insignificant. To qualify as an eligible loan under the CARES Act, a loan modification must be 1) related to COVID-19; 2) executed on a loan that was not more than 30 days past due as of December 31, 2019; and 3) executed between March 1, 2020, and the earlier of a) 60 days after the date of termination of the national emergency by the President or b) December 31, 2020. The CAA, 2021 provides additional COVID-19 emergency response and relief, including extending relief offered under the CARES Act related to TDRs as a result of COVID-19 through January 1, 2022 or 60 days after the end of the national emergency declared by the President, whichever is earlier.

On April 7, 2020, the federal banking regulators issued a revised interagency statement on loan modifications and the reporting for financial institutions working with customers affected by the COVID-19 pandemic ("Interagency Statement"). The Interagency Statement confirmed that COVID-19 related short-term loan modifications (e.g., payment deferrals of six months or less) provided to borrowers that were current (less than 30 days past due) at the time the relief was granted are not TDR loans. Borrowers that do not meet the criteria in the CARES Act or the Interagency Statement are assessed for TDR loan classification in accordance with the Company’s accounting policies. All loans modified due to COVID-19 are separately monitored and any request for continuation of relief beyond the initial modification will be reassessed at that time to determine if a further modification should be granted and if a downgrade in risk rating is appropriate. Loan modifications in accordance with the CARES Act and related banking agency regulatory guidance are still subject to an evaluation in regards to determining whether or not a loan is deemed to be impaired. As of September 30, 2021, there were no loans still on deferral.

Regulatory Matters

The Bank, as a state-chartered, federally insured savings bank, is subject to the capital requirements established by the FDIC. Under the FDIC's capital adequacy guidelines and the regulatory framework for prompt corrective action, the Bank must meet specific capital guidelines that involve quantitative measures of the Bank's assets, liabilities and certain off-balance-sheet items as calculated under regulatory accounting practices. The Bank's capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weighting and other factors.

The Company is a bank holding company registered with the Federal Reserve. Bank holding companies are subject to capital adequacy requirements of the Federal Reserve under the Bank Holding Company Act of 1956, as amended, and the regulations of the Federal Reserve. For a bank holding company with less than $3.0 billion in assets, the capital guidelines apply on a bank only basis and the Federal Reserve expects the holding company's subsidiary banks to be well-capitalized under the prompt corrective action regulations. If Security Federal Corporation was subject to regulatory guidelines for bank holding companies with $3.0 billion or more in assets, it would have exceeded all regulatory capital requirements with Common Equity Tier 1 ("CET1") capital, Tier 1 leverage-based capital, Tier 1 risk-based capital and total risk-based capital ratios of 16.6%, 9.0%, 16.6% and 22.5%, respectively, at September 30, 2021.

Based on its capital levels at September 30, 2021, the Bank exceeded all regulatory capital requirements as of that date. Consistent with the Bank's goals to operate a sound and profitable organization, it is the Bank's policy to maintain a "well-capitalized" status under the regulatory capital categories of the FDIC. Based on capital levels at September 30, 2021, the Bank was considered to be "well-capitalized" under applicable regulatory requirements. Management monitors the capital levels to provide for current and future business opportunities and to maintain the Bank's "well-capitalized" status.

The tables below provide the Bank’s regulatory capital requirements and actual results at the dates indicated.

	Actual			For Capital Adequacy			To Be "Well-Capitalized"
	Amount		Ratio	Amount		Ratio	Amount		Ratio
September 30, 2021	Dollars in Thousands
Tier 1 Risk-Based Core Capital (To Risk Weighted Assets)	$	121,421	18.8%	$	38,751	6.0%	$	51,669	8.0%
Total Risk-Based Capital (To Risk Weighted Assets)	129,532		20.1%	51,669		8.0%	64,586		10.0%

Tier 1 Risk-Based Core Capital (To Risk Weighted Assets)	$	109,673	18.6%	$	35,330	6.0%	$	47,107	8.0%
Total Risk-Based Capital (To Risk Weighted Assets)	117,101		19.9%	47,107		8.0%	58,884		10.0%
Common Equity Tier 1 Capital (To Risk Weighted Assets)	109,673		18.6%	26,498		4.5%	38,275		6.5%
Tier 1 Leverage (Core) Capital (To Adjusted Tangible Assets)	109,673		9.8%	44,957		4.0%	56,197		5.0%

In addition to the minimum capital requirements, the Bank must maintain a capital conservation buffer, which consists of additional CET1 capital greater than 2.5% of risk weighted assets above the required minimum levels in order to avoid limitations on paying dividends, repurchasing shares, and paying discretionary bonuses. At September 30, 2021 the Bank’s conservation buffer was 12.1%.

Carrying Amounts and Fair Value of Financial Instruments

Fair Value Disclosures [Abstract]

Carrying Amounts and Fair Value of Financial Instruments

Carrying Amounts and Fair Value of Financial Instruments

GAAP requires the Company to disclose fair value of financial instruments measured at amortized cost on the balance sheet and to measure that fair value using an exit price notion, the price that would be received for an asset or paid to transfer a liability, in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date under current market conditions.

Accounting guidance emphasizes that fair value is a market-based measurement, not an entity-specific measurement. Therefore, a fair value measurement should be determined based on the assumptions that market participants would use in pricing the asset or liability. As a basis for considering market participant assumptions in fair value measurements, the guidance establishes a fair value hierarchy that distinguishes between market participant assumptions based on market data obtained from sources independent of the reporting entity (observable inputs that are classified within Levels 1 and 2 of the hierarchy) and the reporting entity’s own assumptions about market participant assumptions (unobservable inputs classified within Level 3 of the hierarchy). The following three levels of inputs may be used to measure fair value:

Level 1 -	Quoted Market Price in Active Markets Valuation is based upon quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access. Level 1 assets and liabilities include debt and equity securities and derivative contracts that are traded in an active exchange market, as well as U.S. Treasuries and money market funds.
Level 2 -	Significant Other Observable Inputs Valuation is based upon quoted prices for similar assets and liabilities in active markets, as well as inputs that are observable for the asset or liability (other than quoted prices), such as interest rates, foreign exchange rates, and yield curves that are observable at commonly quoted intervals. Level 2 assets and liabilities include debt securities with quoted prices that are traded less frequently than exchange-traded instruments, mortgage-backed securities, municipal bonds, corporate debt securities and derivative contracts whose value is determined using a pricing model with inputs that are observable in the market or can be derived principally from or corroborated by observable market data. This category generally includes certain derivative contracts.
Level 3 -	Significant Unobservable Inputs Valuation is generated from model-based techniques that use at least one significant assumption based on unobservable inputs for the asset or liability, which are typically based on an entity’s own assumptions, as there is little, if any, related market activity. In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. The assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the asset or liability.

The following is a description of the valuation methodologies used for assets and liabilities recorded at fair value.

Investment Securities Available for Sale

Investment securities available for sale are recorded at fair value on a recurring basis. At September 30, 2021, the Company’s investment portfolio was comprised of student loan pools, government and agency bonds, mortgage-backed securities issued by government agencies or GSEs, private label CMO mortgage-backed securities and municipal securities. Fair value measurement is based upon prices obtained from third party pricing services that use independent pricing models which rely on a variety of factors including reported trades, broker/dealer quotes, benchmark yields, economic and industry events and other relevant market information. As a result, these securities are classified as Level 2.

Mortgage Loans Held for Sale

The Company originates fixed rate residential loans on a servicing released basis in the secondary market. Loans closed but not yet settled with the FHLMC or other investors, are carried in the Company’s loans held for sale portfolio.  These loans are fixed rate residential loans that have been originated in the Company’s name and have closed.  Virtually all of these loans have commitments to be purchased by investors and the majority of these loans were locked in by price with the investors on the same day or shortly thereafter that the loan was locked in with the Company’s customers.  Therefore, these loans present very little market risk for the Company. The Company usually delivers a commitment to, and receives funding from, the investor within 30 days.  Commitments to sell these loans to the investor are considered derivative contracts and are sold to investors on a “best efforts" basis. The Company is not obligated to deliver a loan or pay a penalty if a loan is not delivered to the investor. As a result of the short-term nature of these derivative contracts, the fair value of the mortgage loans held for sale in most cases is the same as the value of the loan amount at its origination. These loans are classified as Level 2.

Impaired Loans

The Company does not record loans held for investment at fair value on a recurring basis. However, from time to time, a loan is considered impaired and an allowance for loan losses is established as necessary. Loans for which it is probable that payment of interest and principal will not be made in accordance with the contractual terms of the loan agreement are considered impaired. Once a loan is identified as impaired, management measures the impairment by determining the fair value of the collateral for the loan.

Fair value is estimated using one of the following methods: fair value of the collateral less estimated costs to sell, discounted cash flows, or market value of the loan based on similar debt. The fair value of the collateral less estimated costs to sell is the most frequently used method. Typically, the Company reviews the most recent appraisal and if it is over 24 months old will request a new third party appraisal. Depending on the particular circumstances surrounding the loan, including the location of the collateral, the date of the most recent appraisal and the value of the collateral relative to the recorded investment in the loan, management may order an independent appraisal immediately or, in some instances, may elect to perform an internal analysis. Specifically as an example, in situations where the collateral on a nonperforming commercial real estate loan is out of the Company’s primary market area, management would typically order an independent appraisal immediately, at the earlier of the date the loan becomes nonperforming or immediately following the determination that the loan is impaired. However, as a second example, on a nonperforming commercial real estate loan where management is familiar with the property and surrounding areas and where the original appraisal value far exceeds the recorded investment in the loan, management may perform an internal analysis whereby the previous appraisal value would be reviewed and adjusted for current conditions including recent sales of similar properties in the area and any other relevant economic trends. These valuations are reviewed at a minimum on a quarterly basis.

Those impaired loans not requiring an allowance represent loans for which the fair value of the expected repayments or collateral exceed the recorded investments in such loans. At September 30, 2021, our impaired loans were generally evaluated based on the fair value of the collateral. Impaired loans where an allowance is established based on the fair value of collateral require classification in the fair value hierarchy. The Company records impaired loans as nonrecurring Level 3. At September 30, 2021 and December 31, 2020, the recorded investment in impaired loans was $2.5 million and $2.2 million, respectively.

Foreclosed Assets

Foreclosed assets are adjusted to fair value upon transfer of the loans to foreclosed assets. Subsequently, foreclosed assets are carried at the lower of carrying value or fair value. Fair value is based upon independent market prices, appraised values of the collateral or management’s estimation of the value of the collateral. Foreclosed assets are recorded as nonrecurring Level 3.

Assets measured at fair value on a recurring basis were as follows at September 30, 2021 and December 31, 2020:

There were no liabilities measured at fair value on a nonrecurring basis at September 30, 2021 or December 31, 2020.

For Level 3 assets and liabilities measured at fair value on a recurring or non-recurring basis at September 30, 2021 and December 31, 2020, the significant unobservable inputs used in the fair value measurements were as follows:

	Valuation	Significant	9/30/2021	12/31/2020
Level 3 Assets	Technique	Unobservable Inputs	Range of Inputs	Range of Inputs
Collateral Dependent Impaired Loans	Appraised Value/ Discounted Cash Flows	Discounts to appraised values or cash flows for estimated holding and/or selling costs or age of appraisal	—% - 14%	—% - 14%
Foreclosed Assets	Appraised Value/Comparable Sales	Discounts to appraised values for estimated holding or selling costs	30%	11% - 72%

For assets and liabilities not presented on the balance sheet at fair value, the following methods are used to determine fair value:

Cash and Cash Equivalents—The carrying amount of these financial instruments approximates fair value. All mature within 90 days and do not present unanticipated credit concerns.

Certificates of Deposit with Other Banks—Fair value is based on market prices for similar assets.

Investment Securities Held to Maturity—Securities held to maturity are valued at quoted market prices or dealer quotes.

Loans Receivable, Net—The fair value of loans is estimated using an exit price notion. The exit price notion uses a discounted cash flows technique to calculate the present value of expected future cash flows for a financial instrument and also incorporates other factors, such as enhanced credit risk, illiquidity risk and market factors that sometimes exist in exit prices in dislocated markets. The credit risk assumption is intended to approximate the fair value that a market participant would realize in a hypothetical orderly transaction. The Company’s loan portfolio is initially fair valued using a segmented approach. The Company divides its loan portfolio into the following categories: commercial real estate, other commercial, residential real estate, consumer and all other loans. The results are then adjusted to account for credit risk as described above.

10. Carrying Amounts and Fair Value of Financial Instruments, Continued

A further credit risk discount must be applied through the use of a discounted cash flow model to compensate for illiquidity risk, based on certain assumptions included within the discounted cash flow model, primarily the use of discount rates that better capture inherent credit risk over the lifetime of a loan. This consideration of enhanced credit risk provides an estimated exit price for the Company’s loan portfolio. For variable-rate loans that reprice frequently and have no significant change in credit risk, fair values approximate carrying values.

FHLB Stock—The fair value approximates the carrying value.

Deposits—The fair value of demand deposits, savings accounts, and money market accounts is the amount payable on demand at the reporting date. The fair value of fixed-maturity certificates of deposits is estimated by discounting the future cash flows using rates currently offered for deposits of similar remaining maturities.

FHLB Advances and Borrowings from the FRB—Fair value is estimated using discounted cash flows with current market rates for borrowings with similar terms.

Other Borrowed Money—The carrying value of these short term borrowings approximates fair value.

Subordinated Debentures—The fair value is estimated by discounting the future cash flows using the current rates at which similar debenture offerings with similar terms and maturities would be issued by similar institutions. As discount rates are based on current debenture rates as well as management estimates, the fair values presented may not be indicative of the value negotiated in an actual sale.

Junior Subordinated Debentures—The carrying value of junior subordinated debentures approximates fair value.

The following tables provide a summary of the carrying value and estimated fair value of the Company’s financial instruments at September 30, 2021 and December 31, 2020 presented in accordance with the applicable accounting guidance.

At September 30, 2021, the Bank had $175.5 million in off-balance sheet financial commitments.  These commitments are to originate loans and unused consumer lines of credit and credit card lines.  Because these obligations are based on current market rates, if funded, the original principal amount is considered to be a reasonable estimate of fair value. Fair value estimates are made on a specific date, based on relevant market data and information about the financial instrument.  These estimates do not reflect any premium or discount that could result from offering for sale the Bank’s entire holdings of a particular financial instrument.

Because no active market exists for a significant portion of the Bank’s financial instruments, fair value estimates are based on judgments regarding future expected loss experience, current economic conditions, current interest rates and prepayment trends, risk characteristics of various financial instruments, and other factors.  These estimates are subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision.  Changes in any of these assumptions used in calculating fair value would also significantly affect the estimates. Fair value estimates are based on existing on- and off-balance sheet financial instruments without attempting to estimate the value of anticipated future business and the value of assets and liabilities that are not considered financial instruments.  For example, the Bank has significant assets and liabilities that are not considered financial assets or liabilities including deposit franchise values, loan servicing portfolios, deferred tax liabilities, and premises and equipment.

In addition, the tax ramifications related to the realization of the unrealized gains and losses can have a significant effect on fair value estimates and have not been considered in any of these estimates. The Company has used management’s best estimate of fair value on the above assumptions.  Thus, the fair values presented may not be the amounts, which could be realized, in an immediate sale or settlement of the instrument.  In addition, any income taxes or other expenses that would be incurred in an actual sale or settlement are not taken into consideration in the fair value presented.

Other Income and Expenses [Abstract]

12. Non-Interest Income

Revenue Recognition

In accordance with Topic 606, revenues are recognized when control of promised goods or services is transferred to customers in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. To determine revenue recognition for arrangements that an entity determines are within the scope of Topic 606, the Company performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the Company satisfies a performance obligation.

The Company only applies the five-step model to contracts when it is probable that the entity will collect the consideration it is entitled to in exchange for the goods or services it transfers to the customer. At contract inception, once the contract is determined to be within the scope of Topic 606, the Company assesses the goods or services that are promised within each contract and identifies those that contain performance obligations, and assesses whether each promised good or service is distinct. The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied.

Deposit Fees

The Bank earns fees from its deposit customers for account maintenance, transaction-based and overdraft services.  Account maintenance fees consist primarily of account fees and analyzed account fees charged on deposit accounts on a monthly basis.  The performance obligation is satisfied and the fees are recognized on a monthly basis as the service period is completed. Transaction-based fees on deposits accounts are charged to deposit customers for specific services provided to the customer, such as non-sufficient funds fees, overdraft fees, and wire fees. The performance obligation is completed as the transaction occurs and the fees are recognized at the time each specific service is provided to the customer.

Check Card Fee Income

Check card fee income represents fees earned when a debit card issued by the Bank is used.  The Bank earns interchange fees from debit cardholder transactions through the Mastercard payment network.  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. The performance obligation is satisfied and the fees are earned when the cost of the transaction is charged to the card.  Certain expenses directly associated with the debit card are recorded on a net basis with the fee income.

Trust Income

Trust income includes monthly advisory fees that are based on assets under management and certain transaction fees that are assessed and earned monthly, concurrently with the investment management services provided to the customer. The Bank does not charge performance based fees for its trust services and does not currently have any institutional clients, hedge funds or mutual funds. Although trust income is included within the scope of ASC 606, based on the fees charged by the Bank, there were no changes in the accounting for trust income.  

Gains/Losses on OREO Sales

Gains/losses on the sale of OREO are included in non-interest expense and are generally recognized when the performance obligation is complete. This is typically at delivery of control over the property to the buyer at the time of each real estate closing.

12. Non-Interest Income, Continued

The following table presents the Company's non-interest income for the nine months ended September 30, 2021 and 2020. All of the Company’s revenue from contracts with customers within the scope of ASC 606 is recognized in non-interest income, with the exception of gains on the sale of OREO, which are included in non-interest expense when applicable.

Subsequent Events [Abstract]
Subsequent Events	Subsequent EventsSubsequent 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 estimates inherent in the process of preparing financial statements. Nonrecognized 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 has reviewed all events occurring through the date the consolidated financial statements were available to be issued and determined that there were no subsequent events requiring accrual or disclosure.

Critical Accounting Policies (Policies)

9 Months Ended

Sep. 30, 2021

Accounting Policies [Abstract]

Allowance for Loan Losses

The Company believes the allowance for loan losses is a critical accounting policy that requires the most significant judgments and estimates used in preparation of the consolidated financial statements.  The impact of an unexpected and sudden large loss could deplete the allowance and potentially require increased provisions to replenish the allowance, which would negatively affect earnings. The Company provides for loan losses using the allowance method.  Accordingly, all loan losses are charged to the related allowance and all recoveries are credited to the allowance for loan losses.  Additions to the allowance for loan losses are provided by charges to operations based on various factors, which, in management’s judgment, deserve current recognition in estimating possible losses.  Such factors considered by management include the fair value of the underlying collateral, stated guarantees by the borrower (if applicable), the borrower’s ability to repay from other economic resources, growth and composition of the loan portfolio, the relationship of the allowance for loan losses to the outstanding loans, loss experience, delinquency trends, and general economic conditions.  Management evaluates the carrying value of the loans periodically and the allowance is adjusted accordingly.

3. Critical Accounting Policies, Continued

While management uses the best information available to make evaluations, future adjustments may be necessary if economic conditions differ substantially from the assumptions used in making these evaluations.  The allowance for loan losses is subject to periodic evaluations by our bank regulatory agencies, including the Board of Governors of the Federal Reserve System ("Federal Reserve"), the FDIC and the South Carolina Board of Financial Institutions, which may require adjustments to be made to the allowance based upon the information that is available at the time of their examination.

The Company values impaired loans at the loan’s fair value if it is probable that the Company will be unable to collect all amounts due according to the terms of the loan agreement at the present value of expected cash flows, the market price of the loan, if available, or the value of the underlying collateral.  Expected cash flows are required to be discounted at the loan’s effective interest rate.  When the ultimate collectibility of an impaired loan’s principal is in doubt, wholly or partially, all cash receipts are applied to principal.  When this doubt does not exist, cash receipts are applied under the contractual terms of the loan agreement first to interest and then to principal.  Once the recorded principal balance has been reduced to zero, future cash receipts are applied to interest income to the extent that any interest has been foregone.  Further cash receipts are recorded as recoveries of any amounts previously charged off.

Income Taxes

The Company uses assumptions and estimates in determining income taxes payable or refundable for the current year, deferred income tax liabilities and assets for events recognized differently in its financial statements and income tax returns, and income tax expense. Determining these amounts requires analysis of certain transactions and interpretation of tax laws and regulations. The Company exercises considerable judgment in evaluating the amount and timing of recognition of the resulting tax liabilities and assets. These judgments and estimates are reevaluated on a continual basis as regulatory and business factors change. No assurance can be given that either the tax returns submitted by us or the income tax reported on the consolidated financial statements will not be adjusted by either adverse rulings by the United States Tax Court, changes in the tax code, or assessments made by the Internal Revenue Service.
