Item 1. Business

General

The Bank of South Carolina (the “Bank”) was organized on October 22, 1986 and opened for business as a state-chartered financial institution on February 26, 1987, in Charleston, South Carolina. The Bank was reorganized into a wholly owned subsidiary of the Company, effective April 17, 1995. At the time of the reorganization, each outstanding share of the Bank was exchanged for two shares of Company stock.

Market Area

The Bank operates as an independent, community oriented, commercial bank providing a broad range of financial services and products to the Charleston – North Charleston metro area, which includes Charleston, Berkeley, and Dorchester county. We have five banking house locations: 256 Meeting Street, Charleston, SC; 100 North Main Street, Summerville, SC; 1337 Chuck Dawley Boulevard, Mt. Pleasant, SC; 2027 Sam Rittenberg Boulevard, Charleston, SC; and 9403 Highway 78, North Charleston, SC.

 3

The Charleston – North Charleston metro area grew 16.56% from 2015 to 2019 according to the U.S. Bureau of Economic Analysis based on real gross domestic product. Charleston and Berkeley county are ranked in the top ten economies in the state based on real gross domestic product according to the U.S. Bureau of Economic Analysis. The largest nonfarm employers in our market area are trade, transportation, and utilities; government; and professional and business services. Trade, transportation and utilities has been the main economic driver of the growth in the area over the last five years. This includes manufacturing campuses for Boeing, Volvo Cars, and Mercedes-Benz Vans in the area. Based on October 2020 Bureau of Labor Statistics, the Charleston area unemployment rate was 4.0% compared to the 6.6% nationally. The Charleston area continues to rank higher than the other major metropolitan areas of the state of South Carolina in talent, innovative capacity, entrepreneurial and business environment, and livability.

References to “we,” “us,” “our,” “the Bank,” or “the Company” refer to the parent and its subsidiary, that are consolidated for financial purposes.

The Company (ticker symbol: BKSC) is publicly traded on the National Association of Securities Dealers Automated Quotations (“NASDAQ”), and is under the reporting authority of the SEC. All of our electronic filings with the SEC, including our Annual Report on Form 10-K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K and other documents filed or furnished pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934, are accessible at no cost on our website, http://www.banksc.com, through the “Investor Relations” link. Our filings are also available through the SEC’s web site at http://www.sec.gov or by calling 1-800-SEC-0330.

Competition

The financial services industry is highly competitive. We face competition in attracting deposits and originating loans based upon a variety of factors including:

● interest rates offered on deposit accounts

● interest rates charged on loans

● credit and service charges

● the quality of services rendered

● the convenience of banking facilities and other delivery channels

● relative lending limits in the case of loans

● increase in non-banking financial institutions providing similar services

● continued consolidation, and

● legislative, regulatory, economic, and technological changes.

We compete with commercial banks, savings institutions, finance companies, credit unions and other financial services companies. Many of our larger commercial bank competitors have greater name recognition and offer certain services that we do not. However, we believe that we have developed an effective competitive advantage in our market area by emphasizing exceptional service and knowledge of local trends and conditions.

Lending Activities

We focus our lending activities on small and middle market businesses, professionals and individuals in our geographic markets and typically require personal guarantees. Our primary lending activities are for commercial, commercial real estate, and consumer purposes, with the largest category being commercial real estate. Most of our lending activity is to borrowers within our market area.

Commercial Loans

As of December 31, 2020, $51.0 million, or 15.91%, of our loan portfolio consisted of commercial loans. We originate various types of secured and unsecured commercial loans to customers in our market area in order to provide customers with working capital and funds for other general business purposes. The terms of these loans generally range from less than one year to 10 years. These loans bear either a fixed interest rate or an interest rate linked to a variable market index, depending on the individual loan, its purpose, and underwriting of that loan.

Commercial credit decisions are based upon our credit assessment of each applicant. We evaluate the applicant’s ability to repay in accordance with the proposed terms of the loan and assess the risks involved. In addition to evaluating the applicant’s financial statements, we consider the adequacy of the primary and secondary sources of repayment for the loan. Credit agency reports of the applicant’s personal credit history supplement our analysis of the applicant’s creditworthiness. In addition, collateral supporting a secured transaction is analyzed to determine its marketability. Commercial business loans generally have higher interest rates than residential loans of a similar duration because they have a higher risk of default with repayment generally depending on the successful operation of the borrower’s business and the adequacy of any collateral.

 4

Commercial Real Estate Loans

As of December 31, 2020, commercial real estate construction loans comprised $14.8 million, or 4.62%, of our loan portfolio. We make construction loans for commercial properties to businesses. Advances on construction loans are made in accordance with a schedule reflecting the cost of construction. Loans are typically underwritten with a maximum loan to value ratio of 80% based on current appraisals with value defined as the purchase price, appraised value, or cost of construction, whichever is lower. Repayment of construction loans on non-residential and income-producing properties is normally attributable to rental income, income from the borrower’s operating entity, or the sale of the property. Construction loans are interest-only during the construction period, which typically does not exceed twelve months, and are often amortized or paid-off with permanent financing.

Before making a commitment to fund a construction loan, we require an appraisal of the property by a state-certified or state-licensed appraiser. We review and inspect properties before disbursement of funds during the term of the construction loan.

Construction financing generally involves greater credit risk than long-term financing on improved, owner-occupied real estate. Risk of loss on a construction loan depends largely upon the accuracy of the initial estimated value of the property at completion of construction compared to the estimated cost (including interest) of construction and other assumptions. Construction loans also expose us to risk that improvements will not be completed on time in accordance with specifications and projected costs.

As of December 31, 2020, $146.2 million, or 45.57%, of our loan portfolio consisted of other commercial real estate loans, excluding commercial construction loans. Properties securing our commercial real estate loans are primarily comprised of business owner-occupied properties, small office buildings and office suites, and income-producing real estate.

We base our decision to lend primarily on the economic viability of the property and the creditworthiness of the borrower. In evaluating a proposed commercial real estate loan, we emphasize the ratio of the property’s projected net cash flow to the loan’s debt service requirement computed after a deduction for an appropriate vacancy factor and reasonable expenses. We typically require property casualty insurance, title insurance, earthquake insurance, wind and hail coverage, and, if appropriate, flood insurance, in order to protect our security interest in the underlying property.

Commercial real estate loans generally carry higher credit risks, as they typically involve larger loan balances concentrated with single borrowers or a group of related borrowers. In addition, the payment of loans secured by income-producing properties typically depends on the successful operation of the property, as repayment of the loan generally is largely dependent upon sufficient income from the property to cover operating expenses and debt service. Changes in economic conditions not within the control of the borrower or lender could affect the value of the underlying collateral or the future cash flow of the property.

Consumer Loans

Consumer real estate loans were $71.8 million, or 22.39%, of the loan portfolio as of December 31, 2020. Consumer real estate loans consist of consumer construction loans, HELOCs, and mortgage originations. We make mortgage and construction loans for owner-occupied residential properties. Advances on construction loans are in accordance with a schedule reflecting the cost of construction, but are limited to a maximum loan-to-value ratio of 80%. Before making a commitment to fund a construction loan, we require an appraisal of the property by a state-certified or state-licensed appraiser. We review and inspect properties before disbursement of funds during the term of the construction loan. Similar to commercial real estate construction financing, consumer construction financing generally involves greater credit risk than long-term financing on improved, owner-occupied real estate. Risk of loss on a construction loan depends largely upon the accuracy of the initial estimated value of the property at completion of construction compared to the estimated cost (including interest) of construction and other assumptions. Construction loans also expose us to risk that improvements will not be completed on time in accordance with plans, specifications, and projected costs.

This category of loans consists of loans secured by first or second mortgages on primary residences and originate as adjustable-rate or fixed-rate loans. Owner-occupied properties located in the Company’s market area serve as the collateral for these loans. The Company currently originates residential mortgage loans for our portfolio with a maximum loan-to-value ratio of 80% for traditional owner-occupied homes.

We offer home equity loans and lines of credit secured by the borrower’s primary or secondary residence. Our home equity loans and lines of credit currently originate with an adjustable- rate with a floor. We generally underwrite home equity loans and lines of credit with the same criteria that we use to underwrite mortgage loans to be sold. For a borrower’s primary and secondary residences, home equity loans and lines of credit are typically underwritten with a maximum loan-to-value ratio of 80% when combined with the principal balance of the existing mortgage loan. We require a current appraisal or internally prepared real estate evaluations on home equity loans and lines of credit. At the time we close a home equity loan or line of credit, we record a mortgage to perfect our security interest in the underlying collateral.

 5

Other consumer loans totaled $4.5 million, or 1.40% of the loan portfolio, as of December 31, 2020. These loans are originated for various purposes, including the purchase of automobiles, boats, and other personal items or needs.

Consumer loans may entail greater credit risk than mortgage loans to be sold, particularly in the case of consumer loans that are unsecured or are secured by rapidly depreciable assets, such as automobiles. In addition, consumer loan collections are dependent on the borrower’s continuing financial stability, and thus are more likely to be affected by adverse personal circumstances. The application of various federal and state laws, including bankruptcy and insolvency laws, may also limit the amount which can be recovered on such loans.

Paycheck Protection Program

Paycheck Protection Program (“PPP”) loans were $32.4 million, or 10.11% of the loan portfolio, as of December 31, 2020. On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) was signed into law, which established the Paycheck Protection Program (“PPP”) and allocated $349.0 billion of loans to be issued by financial institutions. Under the program, the Small Business Administration (“SBA”) will forgive loans, in whole or in part, made by approved lenders to eligible borrowers for Paycheck and other permitted purposes in accordance with the requirements of the program. These loans were originated to assist small businesses affected by the coronavirus. The Bank originated $37.8 million in PPP loans to 266 customers as of December 31, 2020.

These loans are 100% guaranteed by the SBA.

Loan Approval Procedures and Authority

Our lending activities follow written, non-discriminatory underwriting standards and loan origination procedures established by the Board of Directors of the Bank. The loan approval process is intended to assess the borrower’s ability to repay the loan and the value of the collateral that will secure the loan. To assess the borrower’s ability to repay, we review the borrower’s employment, credit history, and other information on the historical and projected income and expenses of the borrower.

The objectives of our lending program are to:

1. Establish a sound asset structure

2. Provide a sound and profitable loan portfolio to:

a) Protect the depositor’s funds

b) Maximize the shareholders’ return on their investment

3. Promote the stable economic growth and development of the market area served by the Bank

4. Comply with all regulatory agency requirements and applicable law

The underwriting standards and loan origination procedures include officer lending limits, which are approved by the Board of Directors. The individual secured/unsecured lending authority of the President/Chief Executive Officer of the Bank is set at $1,500,000 and the individual secured/unsecured lending authority of the Senior Lender/Executive Vice President is set at $750,000. The President/Chief Executive Officer of the Bank and the Senior Lender/Executive Vice President may jointly lend up to 10% of the Bank’s unimpaired capital for the previous quarter end. In the absence of either of the above, the other may, jointly with the approval of either the Chairman of the Board of Directors or a majority of the Loan Committee of the Board of Directors, lend up to 10% of the Bank’s unimpaired capital for the previous quarter end. The Board of Directors, with two-thirds vote, may approve the aggregate credit in excess of this limit but may not exceed 15% of the Bank’s unimpaired capital. Loan limits apply to the total direct and indirect liability of the borrower. All loans above the loan officer’s authority must have the approval of a loan officer with the authority to approve a loan of that amount. Pooling of loan authority is not allowed except as outlined above for the President/Chief Executive Officer, Senior Lender/Executive Vice President, Chairman of the Board of Directors, and a majority of the Loan Committee or two-thirds of the Board of Directors.

All new credit which results in aggregate direct, indirect, and related credit, not under an approved line of credit of a threshold set forth in our loan policy, with the exceptions of mortgage loans in the process of being sold to investors and loans secured by properly margined negotiable securities traded on an established market or other cash collateral, are reviewed in detail on a monthly basis by the Loan Committee. Certain new credits that meet a higher threshold than required for the Loan Committee are reviewed by the Board of Directors of the Bank at its regular monthly meeting.

Employees

At December 31, 2020, we employed 76 people, with two individuals considered hourly, none of whom are subject to a collective bargaining agreement. We provide a variety of benefit programs including an Employee Stock Ownership Plan and Trust; Stock Incentive Plan; and health, life, disability and other insurance. We believe our relationship with our employees is excellent.

Supervision and Regulation

We are subject to extensive state and federal banking laws and regulations that impose specific requirements or restrictions and provide for general regulatory oversight of virtually all aspects of operations. The regulations are primarily intended to protect depositors, customers, and the integrity of the U.S. banking system and capital markets. The following information describes some of the more significant laws and regulations applicable to us. The description is qualified in its entirety by reference to the applicable laws and regulations. Proposals to change the laws and regulations governing the banking industry are frequently raised in Congress, state legislatures, and with the various bank regulatory agencies. Changes in applicable laws or regulations, or a change in the way such laws or regulations are interpreted by regulatory agencies or courts, may have a material impact on our business operations and earnings.

Dodd-Frank Act

On July 21, 2010, the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) became effective. This law has broadly affected the financial services industry by implementing changes to the financial regulatory landscape aimed at strengthening the sound operation of the financial services industry. This legislation will continue to significantly change the current bank regulatory structure and affect the lending, deposit, investment, trading and operating activities of financial institutions and their holding companies, including the Company and the Bank.

The Dodd-Frank Act created the Consumer Financial Protection Bureau (the “CFPB”) to centralize responsibility for consumer financial protection, including implementing, examining and enforcing compliance with federal consumer financial laws. The CFPB exercises supervisory review of banks under its jurisdiction. The CFPB focuses its rulemaking in several areas, particularly in the areas of mortgage reform involving the Real Estate Settlement Procedures Act, the Truth in Lending Act, the Equal Credit Opportunity Act, and the Fair Debt Collection Practices Act. There are many provisions in the Dodd-Frank Act mandating regulators to adopt new regulations and conduct studies upon which future regulation may be based. Governmental intervention and new regulations could materially and adversely affect our business, financial condition and results of operations.

Volcker Rule

Section 619 of the Dodd-Frank Act, known as the “Volcker Rule,” prohibits any bank, bank holding company, or affiliate (referred to collectively as “banking entities”) from engaging in two types of activities: proprietary trading and the ownership or sponsorship of private equity or hedge funds that are referred to as covered funds. Proprietary trading, in general, is trading in securities on a short-term basis for a banking entity’s own account. In December 2013, federal banking agencies, the SEC and the Commodity Futures Trading Commission, finalized a regulation to implement the Volcker Rule. As of December 31, 2020, the Company has evaluated our securities portfolio and has determined that we do not hold any covered funds.

Bank Holding Company Act

The Company is a one-bank holding company under the Federal Bank Holding Company Act of 1956, as amended. As a result, the Company is primarily subject to the supervision, examination and reporting requirements of the Board of Governors (the “Federal Reserve Board”) of the Federal Reserve Bank (the “Federal Reserve”) under the act and its regulations promulgated thereunder.

Capital Requirements

The Federal Reserve Board imposes certain capital requirements on the Company under the Bank Holding Company Act, including a minimum leverage ratio and minimum ratio of “qualifying” capital to risk-weighted assets or a community bank leverage ratio for qualifying community banking organizations. These requirements are essentially the same as those that apply to the Bank and are described under “Regulatory Capital Requirements” in the notes to the financial statements (see Note 18). The ability of the Company to pay dividends to shareholders depends on the Bank’s ability to pay dividends to the Company, which is subject to regulatory restrictions as described below in “Dividends.”

Standards for Safety and Soundness

The Federal Deposit Insurance Act requires the federal banking regulatory agencies to prescribe, by regulation or guidelines, operational and managerial standards for all insured depository institutions relating to (1) internal controls, information systems and internal audit systems, (2) loan documentation, (3) credit underwriting, (4) interest rate risk exposure, and (5) asset growth. The agencies also must prescribe standards for asset quality, earnings, and stock valuation, as well as standards for compensation, fees, and benefits. The federal banking agencies have adopted regulations and “Interagency Guidelines Establishing Standards for Safety and Soundness” to implement these required standards. These guidelines set forth the safety and soundness standards that the federal banking agencies use to identify and address problems at insured depository institutions before capital becomes impaired.

 7

Regulatory Examination

All insured institutions must undergo regular on-site examinations by their appropriate banking agency. The cost of examinations of insured depository institutions and any affiliates may be assessed by the appropriate banking agency against each institution or affiliate, as it deems necessary or appropriate. Insured institutions are required to submit annual reports to the Federal Deposit Insurance Corporation (“FDIC”), their federal regulatory agency, and state supervisor, when applicable. As a state-chartered bank located in South Carolina, the Bank is also subject to the regulations of the South Carolina State Board of Financial Institutions.

The federal banking regulatory agencies prescribe, by regulation, standards for all insured depository institutions and depository institution holding companies relating to, among other things, the following:

● Internal controls

● Information systems and audit systems

● Loan documentation

● Credit underwriting

● Interest rate risk exposure

● Asset quality

● Liquidity

● Capital adequacy

● Bank Secrecy Act

● Sensitivity to market risk

Transactions with Affiliates and Insiders

We are subject to certain restrictions on extensions of credit to executive officers, directors, certain principal shareholders, and their related interests. Such extensions of credit must be made on substantially the same terms, including interest rates, and collateral, as those prevailing at the time for comparable transactions with third parties and must not involve more than the normal risk of repayment or present other unfavorable features.

Dividends

The Company’s principal source of cash flow, including cash flow to pay dividends to its shareholders, is dividends it receives from the Bank. Statutory and regulatory limitations apply to the Bank’s payment of dividends to the Company. As a general rule, the amount of a dividend may not exceed, without prior regulatory approval, the sum of net income in the calendar year to date and the retained net earnings of the immediately preceding two calendar years. A depository institution may not pay any dividend, without regulatory approval, if payment would cause the institution to become undercapitalized or if it already is undercapitalized.

Consumer Protection Regulations

Activities of the Bank are subject to a variety of statutes and regulations designed to protect consumers. Interest and other charges collected by the Bank are subject to state usury laws and federal laws concerning interest rates. Our loan operations are also subject to federal laws applicable to credit transactions, such as:

● The federal Truth-In-Lending Act, which governs disclosures of credit terms to consumer borrowers

● The Home Mortgage Disclosure Act of 1975, which requires financial institutions to provide information to enable the public and public officials to determine whether a financial institution is fulfilling its obligation to help meet the housing needs of the community it serves

● The Fair Lending Act, which requires fair, equitable, and nondiscriminatory access to credit for consumers

● The Equal Credit Opportunity Act, which prohibits discrimination on the basis of race, creed or other prohibited factors in extending credit

● The Fair Credit Reporting Act of 1978, which governs the use and provision of information to credit reporting agencies

● The Fair Debt Collection Act, which governs the manner in which consumer debt may be collected by collection agencies

● The Gramm - Leach - Bliley Act, which governs the protection of consumer information

● The rules and regulations of the various federal agencies charged with the responsibility of implementing such federal laws

The deposit operations of the Bank also are subject to:

● The Right to Financial Privacy Act, which imposes a duty to maintain confidentiality of consumer financial records and prescribes procedures for complying with administrative subpoenas of financial records

 8

● The Electronic Funds Transfer Act and Regulation E, issued by the Federal Reserve Board to implement the act, which govern automatic deposits to and withdrawals from deposit accounts and customer’s rights and liabilities arising from the use of automated teller machines and other electronic banking services

● Regulation DD, which implements the Truth in Savings Act to enable consumers to make informed decisions about deposit accounts at depository institutions.

Enforcement Powers

The Company is subject to supervision and examination by the FDIC, the Federal Reserve and the South Carolina State Board of Financial Institutions. The Bank is subject to extensive federal and state regulations that significantly affect business and activities. These regulatory bodies have broad authority to implement standards and to initiate proceedings designed to prohibit depository institutions from engaging in activities that represent unsafe or unsound banking practices or constitute violations of applicable laws, rules, regulations, administrative orders, or written agreements with regulators. These regulatory bodies are authorized to take action against institutions that fail to meet such standards, including the assessment of civil monetary penalties, the issuance of cease-and-desist orders, and other actions.

Bank Secrecy Act/Anti-Money Laundering

We are subject to the Bank Secrecy Act and other anti-money laundering laws and regulations, including the USA Patriot Act of 2001 (“USA Patriot Act”). We must maintain a Bank Secrecy Act Program that includes established internal policies, procedures, and controls; a designated compliance officer; an ongoing employee-training program; and testing of the program by an independent audit function. The enactment of the USA Patriot Act amended and expanded the focus of the Bank Secrecy Act to facilitate information sharing among governmental entities and the Company for the purpose of combating terrorism and money laundering. It improves anti-money laundering and financial transparency laws, information collection tools and the enforcement mechanics for the U.S. government. These provisions include (a) standards for verifying customer identification at account opening; (b) rules to promote cooperation among financial institutions, regulators, and law enforcement entities in identifying parties that may be involved in terrorism or money laundering; (c) reports by nonfinancial trades and businesses filed with the U.S. Treasury’s Financial Crimes Enforcement Network for transactions exceeding $10,000; (d) suspicious activities reports by brokers and dealers if they believe a customer may be violating U.S. laws; and (e) regulations and enhanced due diligence requirements for financial institutions that administer, maintain, or manage private bank accounts or correspondent accounts for non-U.S. persons.

Similar in purpose to the Bank Secrecy Act, the Office of Foreign Assets Control (“OFAC”), a division of the U.S. Department of Treasury, controls and imposes economic and trade sanctions based on U.S. foreign policy and national security goals against targeted countries and individuals based on threats to foreign policy, national security, or the U.S. economy. OFAC has and will send banking regulatory agencies lists of names of individuals and organizations suspected of aiding, concealing, or engaging in terrorist acts. Among other things, the Bank must block transactions with or accounts of sanctioned persons and report those transactions after their occurrence.

Bank regulators routinely examine institutions for compliance with these obligations and are required to consider compliance in connection with the regulatory review of applications.

Privacy and Credit Reporting

In connection with our lending activities, we are subject to a number of federal laws designed to protect borrowers and promote lending to various sectors of the economy and population. These include the Equal Credit Opportunity Act, the Truth-in-Lending Act, the Home Mortgage Disclosure Act, the Real Estate Settlement Procedures Act, and the Community Reinvestment Act (the “CRA”). The CRA requires the appropriate federal banking agency, in connection with its examination of a bank, to assess the bank’s record in meeting the credit needs of the communities served by the bank, including low and moderate income neighborhoods. Under the CRA, institutions are assigned a rating of “outstanding,” “satisfactory,” “needs to improve,” or “substantial non-compliance.” In addition, federal banking regulators, pursuant to the Gramm-Leach-Bliley Act, have enacted regulations limiting the ability of banks and other financial institutions to disclose nonpublic consumer information to non-affiliated third parties. The regulations require disclosure of privacy policies and allow consumers to prevent certain personal information from being shared with nonaffiliated third parties.

The future payment of cash dividends is subject to the discretion of the Board of Directors and depends on a number of factors including future earnings, financial condition, cash requirements, and general business conditions. Cash dividends, when declared, are paid by the Bank to the Company for distribution to shareholders of the Company. Certain regulatory requirements restrict the dividend amount that the Bank can pay to the Company.

At our December 1995 Board Meeting, the Board of Directors authorized the repurchase of up to 140,918 shares of its common stock on the open market. At our October 1999 Board Meeting, the Board of Directors authorized the repurchase of up to 45,752 shares of its common stock on the open market and again at our September 2001 Board meeting, the Board of Directors authorized the repurchase of up to 54,903 shares of its common stock on the open market. At the Annual Meeting in 2020, the Board of Directors authorized a stock repurchase plan of up to $1.0 million. As of the date of this report, the Company owns 298,466 shares, adjusted for five 10% stock dividends and a 25% stock dividend. At the Annual Meeting in 2007, the shareholders voted to increase the number of authorized shares from 6,000,000 to 12,000,000.

THE BANK OF SOUTH CAROLINA EMPLOYEE STOCK OWNERSHIP PLAN AND TRUST

During 1989, the Board of Directors of the Bank adopted an Employee Stock Ownership Plan and Trust Agreement (“ESOP”) to provide retirement benefits to eligible employees of the Bank for long and faithful service. An amendment and restatement was made to the ESOP effective January 1, 2007 and approved by the Board of Directors on January 18, 2007. Periodically, the Internal Revenue Service (“IRS”) requires a restatement of a qualified retirement plan to ensure that the plan document includes provisions required by legislative and regulatory changes made since the last restatement. There have been no substantive changes to the plan; however, to comply with the IRS rules, the Board of Directors approved a restated plan on January 26, 2012 (incorporated as Exhibit 10.5 in the 2011 10-K) and submitted the plan to the IRS for approval. The IRS issued a determination letter on September 26, 2013, stating that the plan satisfied the requirements of Code Section 4975 (e) (7). On January 26, 2017, the Board of Directors approved a restated plan (incorporated as Exhibit 10.6 in the 2016 10-K). The restated Plan was submitted to the IRS for approval and a determination letter was issued November 17, 2017, stating that the plan satisfies the requirements of Code Section 4975 (e) (7).

 11

The Board of Directors of the Bank approved a cash contribution of $540,000, $510,000, and $420,000 to the ESOP for the fiscal years ended December 31, 2020, 2019, and 2018, respectively. The contributions were made during the respective fiscal years.

An employee of the Bank who is not a member of an ineligible class of employees is eligible to participate in the plan upon reaching 21 years of age and being credited with one year of service (1,000 hours of service). All employees are eligible employees except for the following ineligible classes of employees:

● Employees whose employment is governed by a collective bargaining agreement between employee representatives and the Company in which retirement benefits were the subject of good faith bargaining unless the collective bargaining agreement expressly provides for the inclusion of such employees in the plan

● Employees who are non-resident aliens who do not receive earned income from the Company which constitutes income from sources within the United States

● Any person who becomes an employee as the result of certain asset or stock acquisitions, mergers, or similar transactions (but only during a transitional period)

● Certain leased employees

● Employees who are employed by an affiliated company that does not adopt the plan

● Any person who is deemed by the Company to be an independent contractor on his or her employment commencement date and on the first day of each subsequent plan year, even if such person is later determined by a court or a governmental agency to be or to have been an employee.

The employee may enter the Plan on the January 1^st that occurs nearest the date on which the employee first satisfies the age and service requirements described above. No contributions by employees are permitted. The amount and time of contributions are at the sole discretion of the Board of Directors of the Bank. The contribution for all participants is based solely on each participant’s respective regular or base salary and wages paid by the Bank including commissions, bonuses and overtime, if any.

A participant becomes vested in the ESOP based upon the employee’s credited years of service. The vesting schedule is as follows:

●	1 Year of Service	0% Vested
●	2 Years of Service	25% Vested
●	3 Years of Service	50% Vested
●	4 Years of Service	75% Vested
●	5 Years of Service	100% Vested

The Bank is the Plan Administrator. Eugene H. Walpole, IV, Fleetwood S. Hassell, Sheryl G. Sharry and Douglas H. Sass, currently serve as the Plan Administrative Committee and Trustees for the Plan. At December 31, 2020, the Plan owned 344,384 shares of common stock of the Company.

THE BANK OF SOUTH CAROLINA STOCK INCENTIVE PLAN

We have two Stock Incentive Plans: the first was approved in 2010 with 300,000 (363,000 adjusted for two 10% stock dividends) shares reserved and another Stock Incentive Plan, which was approved in 2020, with 300,000 shares reserved. Under both plans, options are periodically granted to employees at a price not less than the fair market value of the shares at the date of grant. Participating employees become 20% vested after five years and then vest 20% each year until fully vested. The right to exercise each such 20% of the options is cumulative and will not expire until the tenth anniversary of the date of the grant. Employees are eligible to participate in this plan if the Executive/Long-Range Planning Committee, in its sole discretion, and the Compensation Committee as to Executive Officers who are members of the Executive/Long-Range Planning Committee, determines that an employee has contributed or can be expected to contribute to our profits or growth.

The fair value of each option award is estimated on the date of grant using a closed form option valuation (Black-Scholes) model. Expected volatilities are based on historical volatilities of our common stock. The expected term of the options granted will not exceed ten years from the date of grant (the amount of time options granted are expected to be outstanding). The risk-free interest rate for the expected term of the option is based on the U.S. Treasury yield curve in effect at the time of the grant.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Management’s discussion and analysis is included to assist the shareholder in understanding our financial condition, results of operations, and cash flow. This discussion should be reviewed in conjunction with the audited consolidated financial statements and accompanying notes presented in Item 8 of this report and the supplemental financial data appearing throughout this report. Since the primary asset of the Company is its wholly-owned subsidiary, most of the discussion and analysis relates to the Bank.

OVERVIEW

The Company is a bank holding company headquartered in Charleston, South Carolina, with $532.5 million in assets as of December 31, 2020 and net income of $6.5 million for the year ended December 31, 2020. The Company offers a broad range of financial services through its wholly owned subsidiary, the Bank. The Bank is a state-chartered commercial bank, which operates principally in the Charleston, Dorchester, and Berkeley counties of South Carolina. The Bank’s original and current concept is to be a full service financial institution specializing in personal service, responsiveness, and attention to detail to foster long-standing relationships.

We derive most of our income from interest on loans and investment securities. The primary source of funding for making these loans and investment securities is our interest-bearing and non-interest-bearing deposits. Consequently, one of the key measures of our success is the amount of net interest income, or the difference between the income on our interest-earning assets, such as loans and investments, and the expense on our interest-bearing liabilities, such as deposits. Another key measure is the spread between the yield we earn on these interest-earning assets and the rate we pay on our interest-bearing liabilities.

A consequence of lending activities is that we may incur credit losses. The amount of such losses will vary depending upon the risk characteristics of the loan portfolio as affected by economic conditions such as rising interest rates and the financial performance of borrowers. The reserve for credit losses consists of the allowance for loan losses (the “allowance”) and a reserve for unfunded commitments (the “unfunded reserve”). The allowance provides for probable and estimable losses inherent in our loan portfolio while the unfunded reserve provides for potential losses related to unfunded lending commitments. For a detailed discussion on the allowance for loan losses, see “Allowance for Loan Losses”.

In addition to earning interest on loans and investment securities, we earn income through fees and other expenses we charge to the customer. The various components of other income and other expenses are described in the following discussion. The discussion and analysis also identifies significant factors that have affected our financial position and operating results for the year ended as of December 31, 2020 as compared to December 31, 2019 and our operating results for 2019 compared to 2018, and should be read in conjunction with the consolidated financial statements and the related notes included in this report. In addition, a number of tables have been included to assist in the discussion.

CRITICAL ACCOUNTING POLICIES

We have adopted various accounting policies that govern the application of accounting principles generally accepted in the United States (“GAAP”) and with general practices within the banking industry in the preparation of our consolidated financial statements. Our significant accounting policies are set forth in the notes to the consolidated financial statements of this report.

Certain accounting policies involve significant judgments and assumptions made by the Company that have a material impact on the carrying value of certain assets and liabilities. We consider these accounting policies to be critical accounting policies. The judgment and assumptions we use are based on factors that we believe to be reasonable under the circumstances. Because of the number of judgments and assumptions that we make, actual results could differ and have a material impact on the carrying values of our assets and liabilities and our results of operations.

We consider our policy regarding the allowance for loan losses to be our most subjective accounting policy due to the significant degree of judgment. We have developed what we believe to be appropriate policies and procedures for assessing the adequacy of the allowance for loan losses, recognizing that this process requires a number of assumptions and estimates with respect to our loan portfolio. Our assessments may be impacted in future periods by changes in economic conditions, the impact of regulatory examinations and the discovery of information with respect to borrowers, which were not known at the time of the issuance of the consolidated financial statements. For additional discussion concerning our allowance for loan losses and related matters, see “Allowance for Loan Losses”.

COVID-19

On March 11, 2020, the World Health Organization (“WHO”) declared COVID-19 a pandemic. Due to orders issued by the governor of South Carolina and in an abundance of caution for the health of our customers and employees, on March 23, 2020 the Bank closed lobbies to all 5 offices but has remained fully operational.

On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) was signed into law, which established the Paycheck Protection Program (“PPP”) and allocated $349.0 billion of loans to be issued by financial institutions. Under the program, the Small Business Administration (“SBA”) will forgive loans, in whole or in part, made by approved lenders to eligible borrowers for payroll and other permitted purposes in accordance with the requirements of the program. These loans carry a fixed rate of 1.00% and a term of two years, if not forgiven, in whole or in part. The loans are 100% guaranteed by the SBA and as long as the borrower submits its loan forgiveness application within ten months of completion of the covered period, the borrower is not required to make any payments until the forgiveness amount is remitted to the lender by the SBA. The Bank received a processing fee ranging from 1% to 5% based on the size of the loan from the SBA. The fees are deferred and amortized over the life of the loans in accordance with ASC 310-20. The Paycheck Protection Program and Health Care Enhancement Act (“PPP/ HCEA Act”) was signed into law on April 24, 2020. The PPP/HCEA Act authorized additional funding under the CARES Act of $310.0 billion for PPP loans to be issued by financial institutions through the SBA. The Bank has provided $37.8 million in funding to 266 customers through the PPP as of December 31, 2020. Because these loans are 100% guaranteed by the SBA and did not undergo the Bank’s typical underwriting process, they are not graded and do not have an associated reserve.

Borrowers must submit a forgiveness application within ten months of the completion of the covered period. Once the borrower has submitted the application, the Bank has 60 days to review, issue a lender decision, and submit the decision and application to the SBA. Once the application is submitted, the SBA has 90 days to review and remit the appropriate forgiveness amount to the Bank plus any interest accrued through the date of payment. The SBA began accepting PPP Forgiveness Applications on August 10, 2020. As of December 31, 2020, the Bank received 127 PPP forgiveness applications, in the amount of $13.9 million in principal, and submitted 57 applications and decisions to the SBA, in the amount of $5.4 million in principal. Of the 57 PPP submissions, 48 loans, in the amount of $4.6 million, were forgiven as of December 31, 2020. Upon forgiveness the Bank will recognize the deferred fee income in accordance with ASC 310-20. The Bank received processing fees of $1.4 million and recognized $0.6 million during the year ended December 31, 2020.

Regulatory agencies, as set forth in the Interagency Statement on Loan Modifications and Reporting for Financial Institutions Working with Customers Affected by the Coronavirus (initially issued on March 22, 2020 and revised on April 7, 2020), have encouraged financial institutions to work prudently with borrowers who are or may be unable to meet their contractual payment obligations because of the effects of COVID-19. In this statement, the regulatory agencies expressed their view of loan modification programs as positive actions that may mitigate adverse effects on borrowers due to COVID-19 and that the agencies will not criticize institutions for working with borrowers in a safe and sound manner. Moreover, the revised statement provides that eligible loan modifications related to COVID-19 may be accounted for under section 4013 of the CARES Act or in accordance with ASC 310-40. Under Section 4013 of the CARES Act, banks may elect not to categorize loan modifications as TDRs if the modifications are related to COVID-19, executed on a loan that was not more than 30 days past due as of December 31, 2019, and executed between March 1, 2020 and the earlier of December 31, 2020 or 60 days after the date of termination of the National Emergency. All short-term loan modifications made on a good faith basis in response to COVID-19 to borrowers who were current prior to any relief are not considered TDRs. Beginning in March 2020, the Bank provided payment accommodations to customers, consisting of 60-day principal deferral to borrowers negatively impacted by COVID-19. The Bank processed approximately $0.7 million in principal deferments to 84 customers, with an aggregate loan of $29.7 million, during the year ended December 31, 2020. The principal deferments represent 0.24% of our total loan portfolio as of December 31, 2020. The Bank has examined the payment accommodations granted to borrowers in response to COVID-19 and classified 9 loans, with an aggregate loan balance of $4.0 million, that were granted payment accommodations as TDRs given the continued financial difficulty of the customer, associated industry risk, and multiple deferral requests. All other borrowers were current prior to relief, were not experiencing financial difficulty prior to COVID-19, and the Bank determined they were not considered TDRs. Additionally, of the 75 customers that received payment accommodations that are not classified as TDRs, 15 customers, with an aggregate loan balance of $2.9 million, have paid their loan in full, 7 customers, with an aggregate loan balance of $3.3 million, are past due less than 30 days, and 53 customers, with an aggregate loan balance of $18.6 million, have commenced paying as agreed as of December 31, 2020. There are no loans that received payment accommodation past due greater than 30 days. The Bank will continue to examine payment accommodations as requested by our borrowers.

On December 27, 2020, the Economic Aid to Hard-Hit Small Businesses, Nonprofits, and Venues Act (“Economic Aid Act”) was enacted, which reauthorized lending under the PPP program through March 31, 2021, with an additional $325 billion. Under this Act, the SBA will forgive loans, in whole or in part, made by approved lenders to eligible borrowers for payroll and other permitted purposes in accordance with the requirements of the program. These loans carry a fixed rate of 1.00% and a term of five years, if not forgiven, in whole or in part. The loans are 100% guaranteed by the SBA and as long as the borrower submits its loan forgiveness application within ten months of completion of the covered period, the borrower is not required to make any payments until the forgiveness amount is remitted to the lender by the SBA. The Bank will receive a processing fee based on the size of the loan from the SBA and a tiered structure. For loans up to $50,000 in principal, the lender processing fee will be the lesser of 50% of the principal amount or $2,500. For loans between $50,000 and $350,000 in principal, the lender processing fee will be 5% of the principal amount. For loans $350,000 and above, the lender processing fee will be 3% of the principal amount. The fees are deferred and amortized over the life of the loans in accordance with ASC 310-20. As of February 11, 2021 the Bank has received 126 applications with a total loan amount of $13.3 million. Of those 126 applications, the SBA has approved 95 applications in the aggregate amount of $10.7 million.

While the effects of COVID-19 have impacted all industries to varying degrees, the Bank believes the retail and/or service, food and beverage, and short-term rental industries in our geographic area are considered a higher risk due to the primary source of repayment. These industries are dependent upon the hospitality industry and were affected by the mandates issued by the Governor of South Carolina to limit occupancy or close for a period of time.

The table below shows the total loans receivable for these segments as a percentage of total gross loans as of December 31, 2020.

	As of December 31, 2020
	Amount		Percent of Total Loans
Retail and/or service	$	1,630,331		0.51	%
Food and beverage		1,402,001		0.44	%
Short-term rentals		9,663,044		3.01	%
Total	$	12,695,376		3.96	%

These loans have been temporarily downgraded to our “Watch” category; the Bank is continuing to monitor the effects of COVID-19 on these segments of our loan portfolio. During the second quarter of 2020, the Bank granted payment accommodations in the amount of $0.1 million to 14 loans with an aggregate amount of $6.0 million, or 33.59% of these loans, as of June 30, 2020. As of December 31, 2020, 4 loans with an aggregate balance of $2.4 million paid off. Of the remaining 10 loans with an aggregate remaining balance of $3.5 million as of December 31, 2020, 1 loan with a balance of $0.1 million is past due, and 9 loans with an aggregate balance of $3.4 million are paying as agreed. There were principal paydowns of $0.1 million since the second quarter of 2020. The Bank will reevaluate these loans on a quarterly basis based on actual performance as the effects of COVID-19 continue.

Effects of COVID-19 may negatively impact management assumptions and estimates, such as the allowance for loan losses. However, it is difficult to assess or predict how, and to what extent, COVID-19 will affect the Bank in the future.

Net income decreased $0.9 million or 11.72% to $6.5 million, or basic and diluted income per share of $1.17 and $1.14, respectively, for the year ended December 31, 2020 from $7.3 million or basic and diluted income per share of $1.33 and $1.31, respectively, for the year ended December 31, 2019. This decrease was primarily due to interest and fee income received on loans tied to changes in variable interest rates as a result of the significant decrease in interest rates at the Federal Reserve during the end of the first quarter of 2020, combined with below market interest rates on PPP loans. Our returns on average assets and average equity for the year ended December 31, 2020 were 1.29% and 11.96%, respectively, compared to 1.66% and 14.86%, respectively, for the year ended December 31, 2019.

Net interest income decreased $1.2 million or 6.43% to $16.9 million for the year ended December 31, 2020 from $18.1 million for the year ended December 31, 2019. This decrease was primarily due to a decrease in interest and fees on loans. Interest and fees on loans decreased $0.9 million or 5.87% to $15.1 million for the year ended December 31, 2020 from $16.0 million for the year ended December 31, 2019, as the result of changes in variable interest rates as effected by the significant decrease in interest rates at the Federal Reserve during the end of the first quarter of 2020 combined with below market interest rates on PPP loans.

Average earning assets increased $57.9 million or 13.69% to $480.5 million for the year ended December 31, 2020 from $422.6 million for the year ended December 31, 2019. This is primarily related to the increase in the average balance of loans related to the PPP program and interest-bearing deposits at the Federal Reserve.

The provision to the allowance for loan losses for the year ended December 31, 2020 was $240,000 compared to $180,000 for the year ended December 31, 2019. The increase was primarily driven by the composition of our loan portfolio in accordance with our allowance for loan loss methodology. The Board of Directors determined that this provision was appropriate based upon the adequacy of our reserve. Charge-offs of $0.3 million and recoveries of $0.2 million, together with the provision to the allowance, resulted in an allowance for loan losses of $4.2 million or 1.30% of total loans as of December 31, 2020. The allowance for loan losses is 1.45% of total loans net of PPP loans.

Other income increased $1.2 million or 54.87% to $3.4 million for the year ended December 31, 2020, from $2.2 million for the year ended December 31, 2019. Our mortgage banking income increased $1.3 million or 141.04% to $2.3 million for the year ended December 31, 2020 from $0.9 million for the year ended December 31, 2019 due to increased volume associated with lower interest rates. Mortgage banking income is highly influenced by mortgage interest rates and the housing market.

Other expense increased $1.1 million or 9.89% to $11.7 million for the year ended December 31, 2020, from $10.6 million for the year ended December 31, 2019. Salaries and employee benefits increased approximately $0.6 million due to increased salaries and commissions on robust mortgage activity. Net occupancy expense increased approximately $0.6 million due to a full year of occupancy in our new North Charleston branch.

For the year ended December 31, 2020, the Company’s effective tax rate was 23.33% compared to 22.91% during the year ended December 31, 2019.

COMPARISON OF THE YEAR ENDED DECEMBER 31, 2019 TO DECEMBER 31, 2018

Net income increased $0.4 million or 5.71% to $7.3 million, or basic and diluted income per share of $1.33 and $1.31, respectively, for the year ended December 31, 2019 from $6.9 million or basic and diluted income per share of $1.26 and $1.24, respectively, for the year ended December 31, 2018. The increase in net income was primarily due to rising interest rates in the first half of the year on interest-earning assets and a decrease in other operating expenses. Our returns on average assets and average equity for the year ended December 31, 2019 were 1.66% and 14.86%, respectively, compared with 1.61% and 15.85%, respectively, for the year ended December 31, 2018.

Net interest income increased $0.7 million or 3.75% to $18.1 million for the year ended December 31, 2019 from $17.4 million for the year ended December 31, 2018. This increase was primarily due to increases in interest and fees on loans. Interest and fees on loans increased $0.9 million or 5.74% to $16.0 million for the year ended December 31, 2019 from $15.1 million for the year ended December 31, 2018, as the result of the higher Federal Funds target rate set by the Federal Reserve during the first half of the year during an expansion of our loan portfolio.

Average earning assets increased $1.9 million or 0.46% to $422.6 million for the year ended December 31, 2019 from $420.7 million for the year ended December 31, 2018. This is primarily related to the increase in the average balance of loans and interest-bearing deposits at the Federal Reserve offset by decreases in average investment securities.

The provision to the allowance for loan losses for the year ended December 31, 2019 was $180,000 compared to $325,000 for the year ended December 31, 2018. The decrease was primarily driven by the composition of our loan portfolio in accordance with our allowance for loan loss methodology. The Board of Directors determined that this provision was appropriate based upon the adequacy of our reserve. Charge-offs of $407,027 and recoveries of $16,454, together with the provision to the allowance, resulted in an allowance for loan losses of $4.0 million or 1.46% of total loans at December 31, 2019.

Other income increased $0.2 million or 10.23% to $2.2 million for the year ended December 31, 2019, from $2.0 million for the year ended December 31, 2018. Our mortgage banking income increased $0.1 million or 19.54% to $0.9 million for the year ended December 31, 2019 from $0.8 million for the year ended December 31, 2018 due to increased volume. Mortgage banking income is highly influenced by mortgage interest rates and the housing market.

Other expense decreased $0.5 million or 4.14% to $10.6 million for the year ended December 31, 2019, from $11.1 million for the year ended December 31, 2018. Other operating expenses decreased $0.8 million to $2.2 million during the year ended December 31, 2019 from $3.0 million during the year ended December 31, 2018. This decrease is directly related to the amortization expense of $354,888 for our investment in a Federal Rehabilitation Tax Credit that was recorded during the year ended December 31, 2018.

For the year ended December 31, 2019, the Company’s effective tax rate was 22.91% compared to 13.81% during the year ended December 31, 2018. The increase in the effective tax rate is directly related to the expiration of our 2018 investment in a Federal Rehabilitation Tax Credit.

ASSET AND LIABILITY MANAGEMENT

We manage our assets and liabilities to ensure there is sufficient liquidity to enable management to fund deposit withdrawals, loan demand, capital expenditures, reserve requirements, operating expenses, and dividends; and to manage daily operations on an ongoing basis. Funds are primarily provided by the Bank through customer deposits, principal and interest payments on loans, mortgage loan sales, the sale or maturity of securities, temporary investments and earnings. The Asset Liability/Investment Committee (“ALCO”) manages asset and liability procedures though the ultimate responsibility rests with the President/Chief Executive Officer. At December 31, 2020, total assets increased 19.66% to $532.5 million from $445.0 million as of December 31, 2019 and total deposits increased 21.89% to $462.2 million from $379.2 million as of December 31, 2019.

As of December 31, 2020, earning assets, which are composed of U.S. Treasury, Government Sponsored Enterprises and Municipal Securities in the amount of $134.8 million, interest-bearing deposits at the Federal Reserve in the amount of $42.3 million and total loans, including mortgage loans held for sale, in the amount of $333.8 million, constituted approximately 95.95% of our total assets.

The yield on a majority of our earning assets adjusts in tandem with changes in the general level of interest rates. Some of the Company’s liabilities are issued with fixed terms and can be repriced only at maturity.

 17

MARKET RISK

Market risk is the risk of loss from adverse changes in market prices and interest rates. Our risk consists primarily of interest rate risk in our lending and investing activities as they relate to the funding by deposit and borrowing activities.

Our policy is to minimize interest rate risk between interest-earning assets and interest-bearing liabilities at various maturities and to attempt to maintain an asset sensitive position over a one-year period. By adhering to this policy, we anticipate that our net interest margins will not be materially affected, unless there is an extraordinary and or precipitous change in interest rates. The average net interest rate margin for 2020 decreased to 3.52% from 4.28% for 2019. At December 31, 2020 and 2019, our net cumulative gap was liability sensitive for periods less than one year and asset sensitive for periods of one year or more. The reason for the shift in sensitivity is the direct result of management’s strategic decision to invest excess funds held at the Federal Reserve into fixed rate investment securities that match our investment policy objectives. Management is aware of this departure from policy and will continue to closely monitor our sensitivity position going forward.

Since the rates on most of our interest-bearing liabilities can vary on a daily basis, we continue to maintain a loan portfolio priced predominately on a variable rate basis. However, in an effort to protect future earnings in a declining rate environment, we offer certain fixed rates, interest rate floors, and terms primarily associated with real estate transactions. We seek stable, long-term deposit relationships to fund our loan portfolio. Furthermore, we do not have any brokered deposits or internet deposits.

At December 31, 2020, the average maturity of the investment portfolio was 4.57 years with an average yield of 1.60% compared to 2.96 years with an average yield of 2.00% at December 31, 2019.

We do not take foreign exchange or commodity risks. In addition, we do not own mortgage-backed securities nor do we have any exposure to the sub-prime market or any other distressed debt instruments.

The following table summarizes our interest sensitivity position as of December 31, 2020.

LIQUIDITY

Historically, we have maintained our liquidity at levels believed by management to be adequate to meet requirements of normal operations, potential deposit outflows and strong loan demand and still allow for optimal investment of funds and return on assets.

The following table summarizes future contractual obligations as of December 31, 2020.

	Total		Less than one year		One to five years		After five years
Contractual Obligations
(in thousands)
Time deposits	$	20,699	$	18,939	$	1,760	$	—

Total contractual cash obligations	$	38,849	$	19,982	$	6,977	$	11,890

Proper liquidity management is crucial to ensure that we are able to take advantage of new business opportunities as well as meet the credit needs of our existing customers. Investment securities are an important tool in our liquidity management. Our primary liquid assets are cash and due from banks, investments available for sale, interest-bearing deposits at the Federal Reserve, and mortgage loans held for sale. Our primary liquid assets accounted for 36.83% and 34.74% of total assets at December 31, 2020 and 2019, respectively. Investment securities classified as available for sale, which are not pledged, may be sold in response to changes in interest rates and liquidity needs. All of the investment securities presently owned are classified as available for sale. Net cash provided by operations and deposits from customers have been the primary sources of liquidity. At December 31, 2020, we had unused short-term lines of credit totaling approximately $23.0 million (which can be withdrawn at the lender’s option). Additional sources of funds available to us for liquidity include increasing deposits by raising interest rates paid and selling mortgage loans held for sale. We also established a Borrower-In-Custody arrangement with the Federal Reserve. This arrangement permits us to retain possession of assets pledged as collateral to secure advances from the Federal Reserve Discount Window. At December 31, 2020, we could borrow up to $58.7 million. There have been no borrowings under this arrangement.

Our core deposits consist of non-interest bearing demand accounts, NOW accounts, money market accounts, time deposits and savings accounts. We closely monitor our reliance on certificates of deposit greater than $250,000 and other large deposits. We maintain a Contingency Funding Plan (“CFP”) that identifies liquidity needs and weighs alternate courses of action designed to address these needs in emergency situations. We perform a quarterly cash flow analysis and stress test the CFP to evaluate the expected funding needs and funding capacity during a liquidity stress event. We believe our liquidity sources are adequate to meet our operating needs and do not know of any trends, events or uncertainties that may result in a significant adverse effect on our liquidity position. At December 31, 2020 and 2019, our liquidity ratio was 38.63% and 36.18%, respectively.

Average earning assets increased by $57.9 million from 2019 to 2020. This increase is primarily related to the increase in the average balance of loans related to the PPP program and interest-bearing deposits at the Federal Reserve.

As of December 31, 2020, we had no U.S. Treasury Notes or Municipal Securities with an unrealized loss.

As of December 31, 2020, we had four Government-Sponsored Enterprises with an unrealized loss of $160,260 compared to one Government-Sponsored Enterprises with an unrealized loss of $43,100 as of December 31, 2019. The unrealized losses on these securities are related to the changes in the interest rate environment. The contractual terms of these investments do not permit the issuer to settle the securities at a price less than the amortized cost of the investment. Therefore, these investments are not considered other-than-temporarily impaired. We have the ability to hold these investments until market price recovery or maturity.

The primary purpose of the investment portfolio is to fund loan demand, manage fluctuations in deposits and liquidity, satisfy pledging requirements and generate a favorable return on investment.  In doing these things, our main objective is to adhere to sound investment practices.  To that end, all purchases and sales of investment securities are made through reputable securities dealers that have been approved by the Board of Directors. The Board of Directors of the Bank reviews the entire investment portfolio at each regular monthly meeting, including any purchases, sales, calls, and maturities during the previous month.  Furthermore, the Credit Department conducts a financial underwriting assessment of all municipal securities and their corresponding municipalities annually and management reviews the assessments.

LOAN PORTFOLIO COMPOSITION

We focus our lending activities on small and middle market businesses, professionals and individuals in our geographic market. At December 31, 2020, outstanding loans (including deferred loan fees of $676,155) totaled $320.8 million, which equaled 69.41% of total deposits and 60.25% of total assets.

The following table is a schedule of our loan portfolio, excluding both mortgage loans to be sold and deferred loan fees, as of December 31, 2020, compared to the prior four years.

(in thousands)	2020		2019		2018		2017		2016

During the year ended December 31, 2020, total loans increased $46.7 million. This is primarily due to the creation of a residential real estate mortgage portfolio held for investment and participation in the Paycheck Protection Program.

We had no foreign loans or loans to fund leveraged buyouts at any time during the years ended December 31, 2016 through December 31, 2020.

The following table presents the contractual terms to maturity for loans outstanding at December 31, 2020. Demand loans, loans having no stated schedule of repayment or stated maturity, and overdrafts are reported as due in one year or less. The table does not include an estimate of prepayments, which can significantly affect the average life of loans and may cause our actual principal experience to differ from that shown.

IMPAIRED LOANS

A loan is impaired when it is probable that we will be unable to collect all amounts due according to the contractual terms of the loan agreement based on current information and events. All loans with a principal balance over $50,000 placed on non-accrual status are classified as impaired. However, not all impaired loans are on non-accrual status nor do they all represent a loss.

Impairment loss is measured by:

a. The present value of the future cash flow discounted at the loan’s effective interest rate, or

 22

b. The fair value of the collateral if the loan is collateral dependent.

The following is a schedule of our impaired loans and non-accrual loans as of December 31, 2016 through 2020.

	2020		2019		2018		2017		2016
Non-accrual loans	$	1,155,930	$	1,666,301	$	823,534	$	831,859	$	1,741,621
Impaired loans	$	7,805,600	$	4,776,928	$	4,278,347	$	3,724,262	$	5,901,784

Beginning in March 2020, the Bank provided payment accommodations to customers, consisting of 60-day principal deferral to borrowers negatively impacted by COVID-19. The Bank processed approximately $0.7 million in principal deferments to 84 customers, with an aggregate loan of $29.7 million, during the year ended December 31, 2020. The principal deferments represent 0.24% of our total loan portfolio as of December 31, 2020. The Bank has examined the payment accommodations granted to borrowers in response to COVID-19 and classified 9 loans, with an aggregate loan balance of $4.0 million, that were granted payment accommodations as impaired and TDRs given the continued financial difficulty of the customer, associated industry risk, and multiple deferral requests.

TROUBLED DEBT RESTRUCTURINGS

According to GAAP, we are required to account for certain loan modifications or restructurings as a troubled debt restructuring (“TDR”), when appropriate. In general, the modification or restructuring of a debt is considered a TDR if we, for economic or legal reasons related to a borrower’s financial difficulties, grant a concession to the borrower that we would not otherwise consider. Three factors must always be present: 

1. An existing credit must formally be renewed, extended, or modified,  

2. The borrower is experiencing financial difficulties, and  

3. We grant a concession that we would not otherwise consider.

The following is a schedule of our TDR’s including the number of loans represented.

	2020		2019		2018		2017		2016
Number of TDRs	$	14	$	3	$	—	$	1	$	2
Amount of TDRs	$	5,803,163	$	573,473	$	—	$	33,300	$	378,382

The Financial Accounting Standards Board Accounting (“FASB”) Standards Codification (“ASC”) 310-20-35-9 allows a loan to be removed from TDR status if the terms of the loan reflect current market rates and the loan has been performing under modified terms for an extended period of time or under certain other circumstances.

One TDR with a balance of $33,300 at December 31, 2017 was removed from TDR status during the year ended December 31, 2018 since, at the most recent renewal, the loan was amortized at market rate and no concessions were granted. One TDR with a balance of $345,082 at December 31, 2016 paid off during the year ended December 31, 2017. During the year ended December 31, 2016, one TDR was paid off with a balance of $72,919 at December 31, 2015. We do not know of any potential problem loans which will not meet their contractual obligations that are not otherwise discussed herein.

Regulatory agencies, as set forth in the Interagency Statement on Loan Modifications and Reporting for Financial Institutions Working with Customers Affected by the Coronavirus (initially issued on March 22, 2020 and revised on April 7, 2020), have encouraged financial institutions to work prudently with borrowers who are or may be unable to meet their contractual payment obligations because of the effects of COVID-19. In this statement, the regulatory agencies expressed their view of loan modification programs as positive actions that may mitigate adverse effects on borrowers due to COVID-19 and that the agencies will not criticize institutions for working with borrowers in a safe and sound manner. Moreover, the revised statement provides that eligible loan modifications related to COVID-19 may be accounted for under section 4013 of the CARES Act or in accordance with ASC 310-40. Under Section 4013 of the CARES Act, banks may elect not to categorize loan modifications as TDRs if the modifications are related to COVID-19, executed on a loan that was not more than 30 days past due as of December 31, 2019, and executed between March 1, 2020 and the earlier of December 31, 2020 or 60 days after the date of termination of the National Emergency. All short-term loan modifications made on a good faith basis in response to COVID-19 to borrowers who were current prior to any relief are not considered TDRs. Beginning in March 2020, the Bank provided payment accommodations to customers, consisting of 60-day principal deferral to borrowers negatively impacted by COVID-19. The Bank has examined the payment accommodations granted to borrowers in response to COVID-19 and classified 9 loans, with an aggregate loan balance of $4.0 million, that were granted payment accommodations as TDRs given the continued financial difficulty of the customer, associated industry risk, and multiple deferral requests. The Bank will continue to examine payment accommodations as requested by the borrowers.

ALLOWANCE FOR LOAN LOSSES

The allowance for loan losses represents our estimate of probable losses inherent in our loan portfolio. The adequacy of the allowance for loan losses (the “allowance”) is reviewed by the Loan Committee and by the Board of Directors on a quarterly basis. For purposes of this analysis, adequacy is defined as a level sufficient to absorb estimated losses in the loan portfolio as of the balance sheet date presented. To remain consistent with GAAP, the methodology employed for this analysis has been modified over the years to reflect the economic environment and new accounting pronouncements. The Credit Department reviews this calculation on a quarterly basis. In addition, an independent third party validates the allowance calculation on a periodic basis. The methodology is based on a reserve model that is comprised of the three components listed below:

1)	Specific reserve analysis for impaired loans based on FASB ASC 310-10-35, Receivables - Overall
2)	General reserve analysis applying historical loss rates based on FASB ASC 450-20, Contingencies: Loss Contingencies
3)	Qualitative or environmental factors.

Loans greater than $50,000 are reviewed for impairment on a quarterly basis if any of the following criteria are met: 

1)	The loan is on non-accrual
2)	The loan is a troubled debt restructuring
3)	The loan is over 60 days past due
4)	The loan is rated sub-standard, doubtful, or loss
5)	Excessive principal extensions are executed
6)	If we are provided information that indicates we will not collect all principal and interest as scheduled

Impairment is measured by the present value of the future cash flow discounted at the loan’s effective interest rate or the fair value of the collateral if the loan is collateral dependent. An impaired loan may not represent an expected loss.

A general reserve analysis is performed on all loans, excluding impaired loans. This analysis includes a pool of loans that are reviewed for impairment but are not found to be impaired. Loans are segregated into similar risk groups and a historical loss ratio is determined for each group over a five-year period. The five-year average loss ratio by loan type is then used to calculate the estimated loss based on the current balance of each group.

Qualitative and environmental loss factors are also applied against the portfolio, excluding impaired loans. These factors include external risk factors that we believe are representative of our overall lending environment. We believe that the following factors create a more comprehensive loss projection, which we can use to monitor the quality of the loan portfolio.

1)	Portfolio risk
	a)	Levels and trends in delinquencies and impaired loans and changes in loan rating matrix
	b)	Trends in volume and terms of loans
	c)	Over-margined real estate lending risk
2)	National and local economic trends and conditions
3)	Effects of changes in risk selection and underwriting practices
4)	Experience, ability and depth of lending management staff
5)	Industry conditions
6)	Effects of changes in credit concentrations
	a)	Loan concentration
	b)	Geographic concentration
	c)	Regulatory concentration
7)	Loan and credit administration risk
	a)	Collateral documentation
	b)	Insurance risk
	c)	Maintenance of financial information risk

The sum of each component’s analysis contributes to the total “estimated loss” within our portfolio.

Portfolio Risk  

Portfolio risk includes the levels and trends in delinquencies, impaired loans and changes in the loan rating matrix, trends in volume and terms of loans, and overmargined real estate lending. We are satisfied with the stability of the past due and non-performing loans and believe there has been no decline in the quality of our loan portfolio due to any trend in delinquent or adversely classified loans. Sizable unsecured principal balances on a non-amortizing basis are monitored. Although the vast majority of our real estate loans are underwritten on a cash flow basis, the secondary source of repayment is typically tied to our ability to realize the collateral. Accordingly, we closely monitor loan to value ratios. The maximum collateral advance rate is 80% on all real estate transactions, with the exception of raw land at 65% and land development at 70%.

 24

Occasionally, we extend credit beyond our normal collateral advance margins in real estate lending. We refer to these loans as overmargined real estate loans. Although infrequent, the aggregate of these loans represents a notable part of our portfolio. Accordingly, these loans are monitored and the balances reported to the Board of Directors every quarter. An excessive level of this practice (as a percentage of capital) could result in additional regulatory scrutiny, competitive disadvantages and potential losses if forced to convert the collateral. The consideration of overmargined real estate loans directly relates to the capacity of the borrower to repay. We often request additional collateral to bring the loan to value ratio within the policy objectives and require a strong secondary source of repayment.

Although significantly under our policy threshold of 100% of capital (currently approximately $55.0 million), the number of overmargined real estate loans currently totals approximately $2.9 million or approximately 0.89% of our loan portfolio at December 31, 2020 compared to $4.8 million or approximately 1.74% of the loan portfolio at December 31, 2019.

A credit rating matrix is used to rate all extensions of credit and to provide a more specific picture of the risk each loan poses to the quality of the loan portfolio. There are eight possible ratings used to determine the quality of each loan based on the following characteristics: cash flow, collateral quality, guarantor strength, financial condition, management quality, operating performance, the relevancy of the financial statements, historical loan performance, debt coverage ratio, and the borrower’s leverage position. The matrix is designed to meet our standards and expectations of loan quality. It is based on experience with similarly graded loans, industry best practices, and regulatory guidance. Our loan portfolio is graded in its entirety, with the exception of PPP loans. Because PPP loans are 100% guaranteed by the SBA and did not undergo the Bank’s typical underwriting process, they are not graded.

National and local economic trends and conditions   

National and local economic trends and conditions are constantly changing and both positively and negatively impact borrowers. Most macroeconomic conditions are not controllable by us and are incorporated into the qualitative risk factors. Natural and environmental disasters, including the rise of sea levels, political uncertainty, and international instability are a few of the trends and conditions that are currently affecting the national and local economies. Additionally, the national and local economy has been affected by COVID-19 during the year ended December 31, 2020. These changes have impacted borrowers’ ability, in many cases, to repay loans in a timely manner. On occasion, a loan’s primary source of repayment (i.e. personal income, cash flow, or lease income) may be eroded as a result of unemployment, lack of revenues, or the inability of a tenant to make rent payments.

Effects of changes in risk selection and underwriting practices  

The quality of our loan portfolio is contingent upon our risk selection and underwriting practices. All new loans (except for mortgage loans in the process of being sold to investors and loans secured by properly margined negotiable securities traded on an established market or other cash collateral) with exposure over $300,000 are reviewed by the Loan Committee on a monthly basis. The Board of Directors review credits over $750,000 monthly. Annual credit analyses are conducted on credits over $500,000 upon the receipt of updated financial information. Prior to extensions of credit, significant loan opportunities go through sound credit underwriting. Our Credit Department conducts a detailed cash flow analysis on each proposal using the most current financial information.

Experience, ability and depth of lending management staff   

We have over 300 combined years of lending experience among our lending staff. We are aware of the many challenges currently facing the banking industry. As other banks look to increase earnings in the short term, we will continue to emphasize the need to maintain safe and sound lending practices and core deposit growth managed with a long-term perspective.

Industry conditions  

There continues to be an influx of new banks and consolidation of existing banks in our geographic area, which creates pricing competition. We believe that our borrowing base is well established and therefore unsound price competition is not necessary.

Effects of changes in credit concentrations  

The risks associated with the effects of changes in credit concentration include loan, geographic and regulatory concentrations. As of December 31, 2020, one Standard Industrial Code group, activities related to real estate, comprised more than 2% of our total outstanding loans.

Effects of changes in geographic concentrations  

We are located along the coast and on an earthquake fault line, increasing the chances that a natural disaster may impact our borrowers and us. We have a Disaster Recovery Plan in place; however, the amount of time it would take for our customers to return to normal operations is unknown. Our plan is reviewed and tested annually.

Loan and credit administration risk 

Loan and credit administration risk includes collateral documentation, insurance risk and maintaining financial information risk.

 25

The majority of our loan portfolio is collateralized with a variety of our borrowers’ assets. The execution and monitoring of the documentation to properly secure the loan is the responsibility of our lenders and loan department. We require insurance coverage naming us as the mortgagee or loss payee. Although insurance risk is also considered collateral documentation risk, the actual coverage, amounts of coverage and increased deductibles are important to management.

Financial Information Risk includes a function of time during which the borrower’s financial condition may change; therefore, keeping financial information up to date is important to us. Our policy requires all new loans (with a credit exposure of $10,000 or more), regardless of the customer’s history with us, to have updated financial information. In addition, we monitor appraisals closely as real estate values are appreciating.

Based on our analysis of the adequacy of the allowance for loan loss model, we recorded a provision for loan loss of $0.2 million for the year ended December 31, 2020 compared to $0.2 million for the year ended December 31, 2019. At December 31, 2020, the five-year average loss ratios were: 0.19% Commercial, 0.00% Commercial Real Estate Construction, -0.01% Commercial Real Estate Other, 0.03% Consumer Real Estate, and 0.63% Consumer Other.

During the year ended December 31, 2020, to charge-offs of $0.3 million and recoveries of $0.2 million were recorded to the allowance for loan losses, resulting in an allowance for loan losses of $4.2 million or 1.30% of total loans compared to charge-offs of $407,027 and recoveries of $16,454 were recorded to the allowance for loan losses, resulting in an allowance for loan losses of $4.0 million or 1.46% of total loans. As of December 31, 2020, the allowance for loan losses was 1.45% of total loans less PPP loans. PPP loans are 100% guaranteed by the SBA; therefore, these loans do not have an associated reserve. We believe loss exposure in the portfolio is identified, reserved against, and closely monitored to ensure that economic changes are promptly addressed in the analysis of reserve adequacy.

The accrual of interest is generally discontinued on loans which become 90 days past due as to principal or interest. The accrual of interest on some loans may continue even though they are 90 days past due if the loans are well secured or in the process of collection and we deem it appropriate. If non-accrual loans decrease their past due status to less than 30 days for a period of six to nine months, they are reviewed individually to determine if they should be returned to accrual status. At December 31, 2020 and 2019, there were no loans over 90 days past due still accruing interest.

The following table represents a summary of loan loss experience for the past five years.

We believe the allowance for loan losses at December 31, 2020, is adequate to cover estimated losses in the loan portfolio; however, assessing the adequacy of the allowance is a process that requires considerable judgment. Our judgments are based on numerous assumptions about current events that we believe to be reasonable, but may or may not be valid. Thus, there can be no assurance that loan losses in future periods will not exceed the current allowance amount or that future increases in the allowance will not be required. No assurance can be given that our ongoing evaluation of the loan portfolio in light of changing economic conditions and other relevant circumstances will not require significant future additions to the allowance, thus adversely affecting our operating results.

The following table presents a breakdown of the allowance for loan losses for the past five years.

⁽¹⁾ Loan category as a percentage of total loans.

The allowance is also subject to examination testing by regulatory agencies, which may consider such factors as the methodology used to determine adequacy and the size of the allowance relative to that of peer institutions and other adequacy tests. In addition, such regulatory agencies could require us to adjust our allowance based on information available to them at the time of their examination.

The methodology used to determine the reserve for unfunded lending commitments, which is included in other liabilities, is inherently similar to the methodology used to determine the allowance for loan losses described above, adjusted for factors specific to binding commitments, including the probability of funding and historical loss ratio. During the year ended December 31, 2020, a provision of $11,894 was recorded compared to a provision of $3,701 during the year ended December 31, 2019. The balance for the reserve for unfunded lending commitments was $44,912 and $33,018 as of December 31, 2020 and 2019, respectively.

Deposits increased $85.0 million or 21.89% to $462.2 million as of December 31, 2020, from $379.2 million as of December 31, 2019. Non-interest bearing deposits increased $43.5 million to $169.2 million as of December 31, 2020, primarily driven by a combination of various government stimulus programs and decreased consumer spending.

We fund growth through core deposits. We do not have, nor do we rely on, Brokered Deposits or Internet Deposits.

SHORT-TERM BORROWINGS

At December 31, 2020 and 2019, we had no outstanding federal funds purchased. We have a Borrower-In-Custody arrangement with the Federal Reserve. This arrangement permits the Company to retain possession of loans pledged as collateral to secure advances from the Federal Reserve Discount Window. Under this agreement, we may borrow up to $58.7 million. We established this arrangement as an additional source of liquidity. There have been no borrowings under this arrangement.

At December 31, 2020 and 2019, the Bank had unused short-term lines of credit totaling approximately $23.0 million (which are withdrawable at the lender’s option).

OFF-BALANCE SHEET ARRANGEMENTS

In the normal course of operations, we engage in a variety of financial transactions that, in accordance with GAAP, are not recorded in the financial statements, or are recorded in amounts that differ from the notional amounts. These transactions involve, to varying degrees, elements of credit, interest rate, and liquidity risk. We use such transactions for general corporate purposes or customer needs. General corporate purpose transactions are used to help manage credit, interest rate and liquidity risk or to optimize capital. Customer transactions are used to manage customer requests for funding.

 28

Our off-balance sheet arrangements consist principally of commitments to extend credit described below. We estimate probable losses related to binding unfunded lending commitments and record a reserve for unfunded lending commitments in other liabilities on the consolidated balance sheet. At December 31, 2020 and 2019, the balance of this reserve was $44,912 and $33,018, respectively. At December 31, 2020 and 2019, we had no interests in non-consolidated special purpose entities.

Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The amount of collateral obtained if deemed necessary by the Company upon extension of credit is based on our credit evaluation of the borrower. Collateral held varies but may include accounts receivable, negotiable instruments, inventory, property, plant and equipment, and real estate. Commitments to extend credit, including unused lines of credit, amounted to $122.8 million and $105.5 million as of December 31, 2020 and 2019, respectively.

Standby letters of credit represent our obligation to a third-party contingent upon the failure of our customer to perform under the terms of an underlying contract with the third party or obligates us to guarantee or stand as surety for the benefit of the third party. The underlying contract may entail either financial or nonfinancial obligations and may involve such things as the shipment of goods, performance of a contract, or repayment of an obligation. Under the terms of a standby letter, generally drafts will be drawn only when the underlying event fails to occur as intended. We can seek recovery of the amounts paid from the borrower. Commitments under standby letters of credit are usually for one year or less. The maximum potential amount of undiscounted future payments related to standby letters of credit at December 31, 2020 and 2019 was $0.8 million and $1.0 million, respectively.

We originate certain fixed rate residential loans and commit these loans for sale. The commitments to originate fixed rate residential loans and the sales commitments are freestanding derivative instruments. We had forward sales commitments, totaling $13.0 million at December 31, 2020, to sell loans held for sale of $13.0 million, compared to forward sales commitments of $5.1 million at December 31, 2019, to sell loans held for sale of $5.1 million. The fair value of these commitments was not significant at December 31, 2020 or 2019. We had no embedded derivative instruments requiring separate accounting treatment.

Once we sell certain fixed rate residential loans, the loans are no longer reportable on our balance sheet. With most of these sales, we have an obligation to repurchase the loan in the event of a default of principal or interest on the loan. This recourse period ranges from three to nine months. Misrepresentation or fraud carries unlimited time for recourse. The unpaid principal balance of loans sold with recourse was $57.2 million at December 31, 2020 and $19.1 million at December 31, 2019. For the twelve months ended December 31, 2020 and December 31, 2019, there were no loans repurchased.

EFFECT OF INFLATION AND CHANGING PRICES

The consolidated financial statements have been prepared in accordance with GAAP, which require the measurement of financial position and results of operations in terms of historical dollars without consideration of changes in the relative purchasing power over time due to inflation.

Unlike most other industries, the assets and liabilities of financial institutions like the Company are primarily monetary in nature. As a result, interest rates generally have a more significant impact on our performance than the effects of general levels of inflation and changes in prices. In addition, interest rates do not necessarily move in the same direction or in the same magnitude as the prices of goods and services. We strive to manage the relationship between interest rate sensitive assets and liabilities in order to protect against wide interest rate fluctuations, including those resulting from inflation.

CAPITAL RESOURCES

Our capital needs have been met to date through the $10.6 million in capital raised in our initial offering, the retention of earnings less dividends paid and the exercise of options to purchase stock. Total shareholders’ equity at December 31, 2020 was $55.0 million. The rate of asset growth since our inception has not negatively impacted our capital base.

On July 2, 2013, the Federal Reserve Board approved the final rules implementing the Basel Committee on Banking Supervision’s (“BCBS”) capital guidelines for U.S. banks (“Basel III”). Following the actions by the Federal Reserve, the FDIC also approved regulatory capital requirements on July 9, 2013. The FDIC’s rule is identical in substance to the final rules issued by the Federal Reserve Bank.

Basel III became effective on January 1, 2015. The purpose is to improve the quality and increase the quantity of capital for all banking organizations. The minimum requirements for the quantity and quality of capital were increased. The rule includes a new common equity Tier 1 capital to risk-weighted assets ratio of 4.5% and a common equity Tier 1 capital conservation buffer of 2.5% of risk-weighted assets. The rule also raises the minimum ratio of Tier 1 capital to risk-weighted assets from 4% to 6% and requires a minimum leverage ratio of 4%. In addition, the rule also implements strict eligibility criteria for regulatory capital instruments and improves the methodology for calculating risk-weighted assets to enhance risk sensitivity. Full compliance with all of the final rule requirements will be phased in over a multi-year schedule.

 29

On November 4, 2019, the federal banking agencies jointly issued a final rule on an optional, simplified measure of capital adequacy for qualifying community banking organizations called the community bank leverage ratio (“CBLR”) framework effective on January 1, 2020. A qualifying community banking organization is defined as having less than $10 billion in total consolidated assets, a leverage ratio greater than 9%, off-balance sheet exposures of 25% or less of total consolidated assets, and trading assets and liabilities of 5% or less of total consolidated assets. Additionally, the qualifying community banking institution must be a non-advanced approaches FDIC supervised institution. The final rule adopts Tier 1 capital and existing leverage ratio into the CBLR framework. The Bank adopted this rule as of September 30, 2020 and will no longer be subject to other capital and leverage requirements. A CBLR bank meeting qualifying criterion is deemed to have met the “well capitalized” ratio requirements and be in appliance with the generally applicable capital rule. The Bank’s CBLR as of December 31, 2020 was 10.19%. As of December 31, 2020, the Company and the Bank were categorized as “well capitalized.” We believe, as of December 31, 2020, that the Company and the Bank meet all capital adequacy requirements to which we are subject.

There are no current conditions or events that we are aware of that would change the Company’s or the Bank’s category.

Please see “Notes to Consolidated Financial Statements” for the Company’s and the Bank’s various capital ratios at December 31, 2020.

Report of Independent Registered Public Accounting Firm

To the Shareholders and Board of Directors of
Bank of South Carolina Corporation 

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Bank of South Carolina Corporation (the “Company”) as of December 31, 2020 and 2019, the related consolidated statements of income, comprehensive income, shareholders’ equity, and cash flows for each of the three years in the period ended December 31, 2020, and the related notes to the consolidated financial statements (collectively, the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2020 and 2019, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2020, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. 

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Allowance for Loan Losses

As described in Note 4 to the Company’s financial statements, the Company has a gross loan portfolio of approximately $320.8 million and related allowance for loan losses of approximately $4.2 million as of December 31, 2020. As described by the Company in Note 1, the evaluation of the allowance for loan losses is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. The allowance for loan losses is evaluated on a regular basis and is based upon the Company’s review of the collectability of the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral, and prevailing economic conditions. 

We identified the Company’s estimate of the allowance for loan losses as a critical audit matter. The principal considerations for our determination of the allowance for loan losses as a critical audit matter related to the high degree of subjectivity in the Company’s judgments in determining the qualitative factors. Auditing these complex judgments and assumptions by the Company involves especially challenging auditor judgment due to the nature and extent of audit evidence and effort required to address these matters, including the extent of specialized skill or knowledge needed. 

The primary procedures we performed to address this critical audit matter included the following: 

• We evaluated the relevance and the reasonableness of assumptions related to evaluation of the loan portfolio, current economic conditions, and other risk factors used in development of the qualitative factors for collectively evaluated loans.

• We evaluated the reasonableness of assumptions and data used by the Company in developing the qualitative factors by comparing these data points internally developed and third-party sources, and other audit evidence gathered.

BANK OF SOUTH CAROLINA CORPORATION 

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. ORGANIZATION

The Bank of South Carolina (the “Bank”) was organized on October 22, 1986 and opened for business as a state-chartered financial institution on February 26, 1987, in Charleston, South Carolina. The Bank was reorganized into a wholly-owned subsidiary of Bank of South Carolina Corporation (the “Company”), effective April 17, 1995. At the time of the reorganization, each outstanding share of the Bank was exchanged for two shares of Bank of South Carolina Corporation Stock.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Our accounting and reporting policies conform, in all material respects, to U.S. generally accepted accounting principles (“GAAP”), and to general practices within the banking industry. The following summarizes the more significant of these policies and practices.

Principles of Consolidation:  

The accompanying consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary, the Bank. In consolidation, all significant intercompany balances and transactions have been eliminated.

References to “we,” “us,” “our,” “the Bank,” or “the Company” refer to the parent and its subsidiary that are consolidated for financial purposes.

Accounting Estimates and Assumptions:  

The financial statements are prepared in conformity with GAAP, which require management to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reported periods. Actual results could differ significantly from these estimates and assumptions. Material estimates generally susceptible to significant change are related to the determination of the allowance for loan losses, impaired loans, other real estate owned, deferred tax assets, the fair value of financial instruments and other-than-temporary impairment of investment securities.

Reclassification:  

Certain amounts in the prior years’ financial statements have been reclassified to conform to the current year’s presentation. Such reclassifications have no effect on shareholders’ equity or the net income as previously reported.

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 as of the date of the balance sheet, including the estimates inherent in the process of preparing financial statements. Non-recognized subsequent events are events that provide evidence about conditions that did not exist as of the date of the balance sheet but arose after that date. We have reviewed events occurring through the date the financial statements were available to be issued and no subsequent events occurred requiring accrual or disclosure.

Cash and Cash Equivalents:  

Cash and cash equivalents include working cash funds, due from banks, interest-bearing deposits at the Federal Reserve, items in process of collection and federal funds sold. All cash equivalents are readily convertible to cash and have maturities of less than 90 days.

Depository institutions are required to maintain reserve and clearing balances at the Federal Reserve Bank. Vault cash satisfied our daily reserve requirement for the years ended December 31, 2020 and 2019, respectively.  

Interest-bearing Deposits at the Federal Reserve:  

Interest-bearing deposits at the Federal Reserve mature daily and are carried at cost.

Investment Securities:  

We classify investments into three categories: (1) Held to Maturity - debt securities that we have the positive intent and ability to hold to maturity, which are reported at amortized cost, adjusted for the amortization of any related premiums or the accretion of any related discounts into interest income using a methodology which approximates a level yield of interest over the estimated remaining period until maturity; (2) Trading - debt and equity securities that are bought and held principally for the purpose of selling them in the near term, which are reported at fair value, with unrealized gains and losses included in earnings; and (3) Available for Sale - debt and equity securities that may be sold under certain conditions, which are reported at fair value, with unrealized gains and losses excluded from earnings and reported as a separate component of shareholders’ equity, net of income taxes. Unrealized losses on securities due to fluctuations in fair value are recognized when it is determined that an other than temporary decline in value has occurred.

37

BANK OF SOUTH CAROLINA CORPORATION 

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Realized gains or losses on the sale of investments are recognized on a specific identification, trade date basis. All securities were classified as available for sale for 2020 and 2019.

Mortgage Loans to be Sold:  

We originate fixed and variable rate residential mortgage loans on a service release basis in the secondary market. Loans closed but not yet settled with an investor are carried in our loans held for sale portfolio.   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 our customers.  Therefore, these loans present very little market risk.  We usually deliver to, and receive funding from, the investor within 30 to 60 days.  Commitments to sell these loans to the investor are considered derivative contracts and are sold to investors on a “best efforts” basis. We are not obligated to deliver a loan or pay a penalty if a loan is not delivered to the investor. Because of the short-term nature of these derivative contracts, the fair value of the mortgage loans held for sale in most cases is materially the same as the value of the loan amount at its origination.

Mortgage loans originated and intended for sale in the secondary market are carried at the lower of cost or estimated market value in the aggregate. Net unrealized losses are provided for in a valuation allowance by charges to operations as a component of mortgage banking income. Gains or losses on sales of loans are recognized when control over these assets are surrendered and are included in mortgage banking income in the consolidated statements of income.

Loans and Allowance for Loan Losses:   

Loans are carried at principal amounts outstanding. Loan origination fees, net of certain direct origination costs, are deferred and recognized over the weighted average life of the loan as an adjustment to yield. Interest income on all loans is recorded on an accrual basis. The accrual of interest and the amortization of net loan fees are generally discontinued on loans that 1) are maintained on a cash basis because of deterioration in the financial condition of the borrower; 2) the payment of full principal is not expected; or 3) the principal or interest has been in default for a period of 90 days or more. We define past due loans based on contractual payment and maturity dates.

The accrual of interest is generally discontinued on loans that become 90 days past due as to principal or interest. The accrual of interest on some loans may continue even though they are 90 days past due if the loans are well secured or in the process of collection and management deems it appropriate. If non-accrual loans decrease their past due status to less than 30 days for a period of six to nine months, they are reviewed individually by management to determine if they should be returned to accrual status.

When the ultimate collectability of an impaired loan’s principal is in doubt, wholly or partially, all cash receipts are applied 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. When this doubt does not exist, cash receipts are applied under the contractual terms of the loan agreement first to interest income and then to principal.  

We account for impaired loans by requiring that all loans (greater than $50,000) where it is estimated that we will be unable to collect all amounts due according to the terms of the loan agreement be recorded at the loan’s fair value. Fair value may be determined based upon the present value of expected future cash flows discounted at the loan’s effective interest rate, or the fair value of the collateral less cost to sell, if the loan is collateral dependent.

Additional accounting guidance allows us to use existing methods for recognizing interest income on an impaired loan. The guidance also requires additional disclosures about how we estimate interest income related to our impaired loans.

A loan is also considered impaired if its terms are modified in a troubled debt restructuring (“TDR”). For this type of impaired loan, cash receipts are typically applied to principal and interest receivable in accordance with the terms of the restructured loan agreement. Interest income is recognized on these loans using the accrual method of accounting, provided they are performing in accordance with their restructured terms.

BANK OF SOUTH CAROLINA CORPORATION 

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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

We believe that the allowance is adequate to absorb inherent losses in the loan portfolio; however, there can be no assurance that loan losses in future periods will not exceed the current allowance amount or that future increases in the allowance will not be required. No assurance can be given that our ongoing evaluation of the loan portfolio, in light of changing economic conditions and other relevant circumstances, will not require significant future additions to the allowance, thus adversely affecting our operating results.

The allowance is also subject to examination by regulatory agencies, which may consider factors such as the methodology used to determine adequacy and the size of the allowance relative to that of peer institutions and other adequacy tests. In addition, such regulatory agencies could require us to adjust our allowance based on information available at the time of the examination.

The methodology used to determine the reserve for unfunded lending commitments, which is included in other liabilities, is inherently similar to the methodology used to determine the allowance adjusted for factors specific to binding commitments, including the probability of funding and historical loss ratio.

Concentration of Credit Risk:  

Our primary market consists of the counties of Berkeley, Charleston and Dorchester, South Carolina. As of December 31, 2020, the majority of the total loan portfolio, as well as a substantial portion of the commercial and real estate loan portfolios, were to borrowers within this region. No other areas of significant concentration of credit risk have been identified.

Premises, Equipment and Leasehold Improvements and Depreciation:  

Land is carried at cost. Buildings and equipment are stated at cost less accumulated depreciation. Depreciation is recorded using the straight-line method for financial reporting purposes and accelerated methods for income tax purposes over the estimated useful lives of the assets ranging from 40 years for buildings and 3 to 15 years for equipment. Leasehold improvements are amortized over the shorter of the asset’s useful life or the remaining lease term, including renewal periods when reasonably assured. The cost of maintenance and repairs is charged to operating expense as incurred.

Leases:

In accordance with ASU 2016-02, the Company determines if a contractual arrangement is a lease at inception. Operating leases are included in the operating right of use (“ROU”) assets and current operating lease liabilities on the Company’s Consolidated Balance Sheet. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Currently, the Company does not have any finance leases.

Beginning January 1, 2019, operating lease ROU assets and lease liabilities are recognized at the commencement of the lease based on the present value of lease payments over the lease term. The lease payments included in the present value are fixed payments and index-based variable lease payments. The Company estimates the incremental borrowing rate, based on information available at the commencement of the lease, as most of the Company’s leases do not include an implicit rate.

Income Taxes:  

We account for income taxes under the asset and liability method. Deferred tax assets and liabilities are recognized for future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using the enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Net deferred tax assets are included in other assets in the consolidated balance sheet.

Accounting standards require the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements. These standards also prescribe a recognition threshold and measurement of a tax position taken or expected to be taken in an enterprise’s tax return. We believe that we had no uncertain tax positions for the years ended December 31, 2020 and 2019.

BANK OF SOUTH CAROLINA CORPORATION 

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Stock-Based Compensation:  

Compensation cost is recognized for stock options issued to employees, based on the fair value of these awards at the date of grant. A Black-Scholes model is utilized to estimate the fair value of stock options. Compensation cost is recognized over the required expected term, generally defined as the average vesting period (7.5 years).

Income Per Common Share:  

Basic income per share is computed by dividing net income by the weighted-average number of common shares outstanding. Diluted earnings per share is computed by dividing net income by the weighted-average number of common shares and potential common shares outstanding. Potential common shares consist of dilutive stock options determined using the treasury stock method and the average market price of common stock. Earnings per share are restated for all stock splits and stock dividends through the date of issuance of the financial statements.

Segment Information:  

The Company operates and manages itself within one retail banking segment and therefore has not provided segment disclosures.

Interest Rate Lock Commitments and Forward Sale Contracts:  

Commitments to fund mortgage loans (interest rate locks) to be sold into the secondary market and forward commitments for the future delivery of these mortgage loans are accounted for as free-standing derivatives. The fair value of the interest rate lock is recorded at the time the commitment to fund the mortgage loan is executed and is adjusted for the expected exercise of the commitments before the loan is funded. In order to hedge the change in interest rates resulting from commitments to fund the loans, we enter into forward commitments for the future delivery of mortgage loans when the interest rate is locked. Fair values of these mortgage derivatives are estimated based on changes in mortgage interest rates from the date the interest on the loan is locked. Changes in the fair values of these derivatives are included in income when they occur. As a result of the short-term nature of mortgage loans held for sale (derivative contract), our derivative instruments were considered to be immaterial as of December 31, 2020 and 2019.

We had no embedded derivative instruments requiring hedge accounting treatment at December 31, 2020. We do not currently engage in hedging activities.

Recent Accounting Pronouncements:  

The following is a summary of recent authoritative pronouncements that could impact the accounting, reporting and/or disclosure of financial information by the Company.

In June 2016, the FASB issued ASU 2016-13, Financial instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, to change the accounting for credit losses and modify the impairment model for certain debt securities. In May 2019, the FASB issued guidance to provide entities with an option to irrevocably elect the fair value option, applied on an instrument-by-instrument basis for eligible instruments, upon adoption of ASU 2016-13, Measurement of Credit Losses on Financial Instruments. In October 2019, the FASB voted to extend the implementation date for smaller reporting companies, non-SEC public companies, and private companies. On March 27, 2020, the Board of Governors of the Federal Reserve, FDIC, and Office of the Comptroller of Currency announced the interim final rule allowing banks to delay the effects of CECL until 2022 for filers scheduled to implement in 2020 and 2023 for all other filers. This amendment will become effective for the Company on January 1, 2023. The Company is currently evaluating the effect that implementation of the new standard will have on its financial position, results of operations, and cash flows. It will be influenced by the quality, composition, and characteristics of our loan and investment portfolios, as well as the expected economic conditions and forecasts at the time of enactment and future reporting periods.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement. The amendments remove, modify, and add certain fair value disclosure requirements based on the concepts in the FASB Concepts Statement, Conceptual Framework for Financial Reporting—Chapter 8: Notes to Financial Statements. The amendment became effective for the Company on January 1, 2020 and did not have a material effect on the financial statements.

In August 2018, the FASB issued ASU 2018-15, Intangibles and Goodwill and Other-Internal Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract), which aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. The amendments became effective for the Company on January 1, 2020 and did not have a material effect on the financial statements.

BANK OF SOUTH CAROLINA CORPORATION 

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

In October 2018, the FASB issued ASU 2018-07, Consolidation (Topic 810): Targeted Improvements to Related Party Guidance for Variable Interest Entities, determining whether a decision-making fee is a variable interest. The amendments require organizations to consider indirect interests held through related parties under common control on a proportional basis rather than as the equivalent of a direct interest in its entirety. The amendment became effective for the Company on January 1, 2020 and did not have a material effect on the financial statements.

In April 2019, the FASB issued guidance that clarifies and improves areas of guidance related to the recently issued standards on credit losses, hedging, and recognition and measurement of financial instruments. The amendments related to credit losses will be effective for the Company for the reporting period beginning after December 15, 2019. The amendments related to hedging became effective January 1, 2019. The amendments related to recognition and measurement of financial instruments became effective for the Company on January 1, 2020 and did not have a material effect on the financial statements.

In July 2019, the FASB updated various Topics of the ASC to align the guidance in various SEC sections of the Codification with the requirements of certain SEC final rules. The amendments were effective upon issuance and did not have a material effect on the financial statements.

In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, which provides guidance to simply accounting for income taxes by removing specific technical exceptions that can produce information investors do not understand. The amendments improve and simplify the application of GAAP for other areas of Topic 740 by clarifying and amending the existing guidance. The amendments are effective for fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. Early adoption is permitted. The Company does not expect these amendments to have a material effect on the financial statements.

In January 2020, the FASB issued guidance to address accounting for the transition into and out of the equity method and measuring certain purchased options and forward contracts to acquire investments. The amendments are effective for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years. Early adoption is permitted, including early adoption in an interim period. The Company does not expect these amendments to have a material effect on its financial statements.

In February 2020, the FASB issued guidance to add and amend SEC paragraphs in the Accounting Standards Codification to reflect the issuance of SEC Staff Accounting Bulletin No. 119 related to the new credit losses standard and comments by the SEC staff related to the revised effective date of the new leases standard. The amendments were effective upon issuance. The Company does not expect these amendments to have a material effect on its financial statements.

In March 2020, the FASB issued guidance that makes narrow-scope improvements to various aspects of the financial instrument guidance, including the current expected credit losses (CECL) guidance issued in 2016. The amendments related to conforming amendments. For public business entities, the amendments are effective upon issuance of this final ASU. The effective date of the amendments to ASU 2016-01 is for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. For the amendments related to ASU 2016-13, public business entities that meet the definition of an SEC filer, excluding eligible smaller reporting companies (SRCs) as defined by the SEC, should adopt the amendments in ASU 2016-13 during 2020. Early adoption will continue to be permitted. For entities that have not yet adopted the guidance in ASU 2016-13, the effective dates and the transition requirements for these amendments are the same as the effective date and transition requirements in ASU 2016-13. The Company does not expect these amendments to have a material effect on its financial statements.

In March 2020, the FASB issued guidance to provide temporary optional guidance to ease the potential burden in accounting for reference rate reform. The amendments are effective as of March 12, 2020 through December 31, 2022. The Company does not expect these amendments to have a material effect on its financial statements.

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

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

We had $76.0 million and $85.2 million of loans pledged as collateral to secure funding with the Federal Reserve Bank (“FRB”) Discount Window at December 31, 2020 and 2019, respectively.

On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) was signed into law, which established the Paycheck Protection Program (“PPP”) and allocated $349.0 billion of loans to be issued by financial institutions. Under the program, the Small Business Administration (“SBA”) will forgive loans, in whole or in part, made by approved lenders to eligible borrowers for payroll and other permitted purposes in accordance with the requirements of the program. These loans carry a fixed rate of 1.00% and a term of two years, if not forgiven, in whole or in part. The loans are 100% guaranteed by the SBA and as long as the borrower submits its loan forgiveness application within ten months of completion of the covered period, the borrower is not required to make any payments until the forgiveness amount is remitted to the lender by the SBA. The Bank received a processing fee ranging from 1% to 5% based on the size of the loan from the SBA. The fees are deferred and amortized over the life of the loans in accordance with ASC 310-20. The Bank received processing fees of $1.4 million and recognized $0.6 million during the year ended December 31, 2020. The Paycheck Protection Program and Health Care Enhancement Act (“PPP/ HCEA Act”) was signed into law on April 24, 2020. The PPP/HCEA Act authorized additional funding under the CARES Act of $310.0 billion for PPP loans to be issued by financial institutions through the SBA. The Bank provided $37.8 million in funding to 266 customers through the PPP as of December 31, 2020. Because these loans are 100% guaranteed by the SBA and did not undergo the Bank’s typical underwriting process, they are not graded and do not have an associated reserve. 

Our portfolio grading analysis estimates the capability of the borrower to repay the contractual obligations of the loan agreements as scheduled. Our internal credit risk grading system is based on experience with similarly graded loans, industry best practices, and regulatory guidance. Our portfolio is graded in its entirety, with the exception of the PPP loans.

Our internally assigned grades pursuant to the Board-approved lending policy are as follows:

● Excellent (1) The borrowing entity has more than adequate cash flow, unquestionable strength, strong earnings and capital, and where applicable, no overdrafts.

● Good (2) The borrowing entity has dependable cash flow, better than average financial condition, good capital and usually no overdrafts.

● Satisfactory (3) The borrowing entity has adequate cash flow, satisfactory financial condition, and explainable overdrafts (if any).

● Watch (4) The borrowing entity has generally adequate, yet inconsistent cash flow, cyclical earnings, weak capital, loan to/from stockholders, and infrequent overdrafts. The borrower has consistent yet sometimes unpredictable sales and growth.

● OAEM (5) The borrowing entity has marginal cash flow, occasional past dues, and frequent and unexpected working capital needs.

● Substandard (6) The borrowing entity has cash flow barely sufficient to service debt, deteriorated financial condition, and bankruptcy is a possibility. The borrowing entity has declining sales, rising costs, and may need to look for secondary source of repayment.

● Doubtful (7) The borrowing entity has negative cash flow. Survival of the business is at risk, full repayment is unlikely, and there are frequent and unexplained overdrafts. The borrowing entity shows declining trends and no operating profits.

● Loss (8) The borrowing entity has negative cash flow with no alternatives. Survival of the business is unlikely.

In general, the modification or restructuring of a debt is considered a troubled debt restructuring (“TDR”) if we, for economic or legal reasons related to a borrower’s financial difficulties, grant a concession to the borrower that we would not otherwise consider. As of December 31, 2020, there were 14 TDRs with a balance of $5.8 million. As of December 31, 2019, there were 3 TDRs with a balance of $573,473. These TDRs were granted extended payment terms with no principal reduction. The structure of two of the loans changed to interest only. All TDRs were performing as agreed as of December 31, 2020. During the year ended December 31, 2019, one TDR in the amount of $2,008 was charged off and the Company recovered $439. No other TDRs that were modified within the previous twelve months defaulted during the following year for the years ended December 31, 2020, 2019, and 2018.

Regulatory agencies, as set forth in the Interagency Statement on Loan Modifications and Reporting for Financial Institutions Working with Customers Affected by the Coronavirus (initially issued on March 22, 2020 and revised on April 7, 2020), have encouraged financial institutions to work prudently with borrowers who are or may be unable to meet their contractual payment obligations because of the effects of COVID-19. In this statement, the regulatory agencies expressed their view of loan modification programs as positive actions that may mitigate adverse effects on borrowers due to COVID-19 and that the agencies will not criticize institutions for working with borrowers in a safe and sound manner. Moreover, the revised statement provides that eligible loan modifications related to COVID-19 may be accounted for under section 4013 of the CARES Act or in accordance with ASC 310-40. Under Section 4013 of the CARES Act, banks may elect not to categorize loan modifications as TDRs if the modifications are related to COVID-19, executed on a loan that was not more than 30 days past due as of December 31, 2019, and executed between March 1, 2020 and the earlier of December 31, 2020 or 60 days after the date of termination of the National Emergency. All short-term loan modifications made on a good faith basis in response to COVID-19 to borrowers who were current prior to any relief are not considered TDRs. Beginning in March 2020, the Bank provided payment accommodations to customers, consisting of 60-day principal deferral to borrowers negatively impacted by COVID-19. The Bank processed approximately $0.7 million in principal deferments to 84 customers, with an aggregate loan balance of $25.9 million, during the year ended December 31, 2020. The principal deferments represent 0.24% of our total loan portfolio as of December 31, 2020. The Bank has examined the payment accommodations granted to borrowers in response to COVID-19 and classified 9 loans, with an aggregate loan balance of $4.0 million, that were granted payment accommodations as TDRs given the continued financial difficulty of the customer, associated industry risk, and multiple deferral requests. All other borrowers were current prior to relief, were not experiencing financial difficulty prior to COVID-19, and the Bank determined they were not considered TDRs. Additionally, of the 75 customers that received payment accommodations that are not classified as TDRs, 15 customers, with an aggregate loan balance of $2.9 million, have paid their loan in full, 7 customers, with an aggregate loan balance of $3.3 million, are past due less than 30 days, and 53 customers, with an aggregate loan balance of $18.6 million, have commenced paying as agreed as of December 31, 2020. There are no loans that received payment accommodation past due greater than 30 days. The Bank will continue to examine payment accommodations as requested by borrowers.

5. CONCENTRATIONS OF CREDIT RISK

We grant short to intermediate term commercial and consumer loans to customers throughout our primary market area of Charleston, Berkeley and Dorchester counties of South Carolina. Our primary market area is heavily dependent on tourism, medical, and legal services. Although we have a diversified loan portfolio, a substantial portion of our debtors’ ability to honor their contracts is dependent upon the stability of the economic environment in their primary market. The majority of the loan portfolio is located in our immediate market area with a concentration in real estate related activities.

Our loans were concentrated in the following categories.

7. LEASES

As of December 31, 2020, the Company had operating right of use (“ROU”) assets of $12.7 million and operating lease liabilities of $12.7 million. The Company maintains operating leases on land, branch facilities, and parking. Most of the leases include one or more options to renew, with renewal terms extending up to 20 years. Leases with an initial term of 12 months or less are not recorded on the balance sheet and are recognized in lease expense.

The weighted average remaining lease term is 17.6 years. The weighted average incremental borrowing rate is 4.35%.

The exercise of renewal options is based on the sole judgement of management and what they consider to be reasonably certain. Based on the market areas, past practices, and contract terms of all leases, the Bank assumed all renewal options will be exercised. Minimum rental commitments for these leases as of December 31, 2020 are presented in the table below.

2021	$	1,043,404

As of December 31, 2020 and 2019, deposits with a deficit balance of $100,304 and $25,319, respectively, were re-classified as other loans.

9. Short-Term Borrowings

At December 31, 2020 and 2019, we had no outstanding federal funds purchased. We have a Borrower-In-Custody arrangement with the Federal Reserve. This arrangement permits the Company to retain possession of loans pledged as collateral to secure advances from the Federal Reserve Discount Window. Under this agreement, we may borrow up to $58.7 million as of December 31, 2020. We established this arrangement as an additional source of liquidity. There have been no borrowings under this arrangement.

At December 31, 2020 and 2019, the Bank had unused short-term lines of credit totaling approximately $23.0 million (which are withdrawable at the lender’s option).

10. Income Taxes

On December 22, 2017, the President of the United States signed into law the 2017 Tax Act. The 2017 Tax Act included a number of changes to the existing U.S. tax laws that impact the Company, most notably a reduction in the U.S. corporate income tax rate from 34 percent to 21 percent for tax years beginning after December 31, 2017.

Total income taxes for the years ended December 31, 2020, 2019 and 2018 are presented in the table below.

In 2018, the Company invested in a Federal Rehabilitation Credit. The tax credit was used during the year ended December 31, 2018. Amortization expense recognized for the years ended December 31, 2019 and 2018 was $8,022 and $354,888, respectively. In 2016, the Company invested in a South Carolina Rehabilitation Credit. The tax credit was included in deferred tax assets and is being amortized. Amortization expense recognized for the year ended December 31, 2018 was $306,105 and was included in other operating expense on the statement of operations.

There was a $89,997 and $81,914 valuation allowance for deferred tax assets at December 31, 2020 and 2019, respectively, associated with the Company’s state tax credits. In assessing the realization of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred income tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible and prior to their expiration governed by the income tax code. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and tax planning strategies in making this assessment. Based upon the level of historical taxable income and projections for future taxable income over the periods during which the deferred income tax assets are expected to be deductible, management believes it is more likely than not the Company will realize the benefits of these deductible differences, net of the existing valuation allowance at December 31, 2020. The amount of the deferred income tax asset considered realizable, however, could be reduced in the near term if estimates of future taxable income during the carry forward period are reduced.

The Company measures deferred tax assets and liabilities using enacted tax rates that will apply in the years in which the temporary differences are expected to be recovered or paid.

The Company has analyzed the tax positions taken or expected to be taken in its tax returns and concluded it has no liability related to uncertain tax positions in accordance with applicable regulations.

Tax returns for 2017 and subsequent years are subject to examination by taxing authorities.

11. Commitments and Contingencies

We are a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of our customers. These financial instruments include commitments to extend credit and standby letters of credit. Those instruments involve, to varying degrees, elements of credit, interest rate, and liquidity risk. Our exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit and standby letters of credit is essentially the same as that involved in extending loan facilities to customers. We use the same credit policies in making commitments and conditional obligations as we do for on-balance sheet instruments.

Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. If deemed necessary, the amount of collateral obtained upon extension of credit is based on our credit evaluation of the borrower. Collateral held varies, but may include accounts receivable, negotiable instruments, inventory, property, plant and equipment, and real estate. Commitments to extend credit, including unused lines of credit, amounted to $122,755,761 and $105,481,545 at December 31, 2020 and 2019, respectively.

Standby letters of credit represent our obligation to a third-party contingent upon the failure by our customer to perform under the terms of an underlying contract with the third party or obligates us to guarantee or stand as surety for the benefit of the third party. The underlying contract may entail either financial or nonfinancial obligations and may involve such things as the shipment of goods, performance of a contract, or repayment of an obligation. Under the terms of a standby letter, generally drafts will be drawn only when the underlying event fails to occur as intended. We can seek recovery of the amounts paid from the borrower. Commitments under standby letters of credit are usually for one year or less. At December 31, 2020 and 2019, we have recorded no liability for the current carrying amount of the obligation to perform as a guarantor; as such amounts are not considered material. The maximum potential amount of undiscounted future payments related to standby letters of credit at December 31, 2020 and 2019 was $845,811 and $1,042,966, respectively.

12. RELATED PARTY TRANSACTIONS

In the opinion of management, loans to our Executive Officers and Directors are made on substantially the same terms, including interest rates and collateral, as those terms prevailing at the time for comparable loans with persons not related to the lender that do not involve more than the normal risk of collectability. There were no past due loans to our Executive Officers and Directors as of December 31, 2020 and 2019.

The table below summarizes related party loans.

	December 31, 2020			December 31, 2019

14. Stock Incentive Plan

We have two employee Stock Incentive Plans: the first plan, which was approved in 2010, has 300,000 (363,000 adjusted for two 10% stock dividends) shares reserved and the second plan, which was approved in 2020, has 300,000 shares reserved. No new options may be granted under the 2010 plan, as it expired on April 14, 2020. Under the 2020 plan, options are periodically granted to employees at a price not less than the fair market value of the shares at the date of grant. Employees become 20% vested after five years and then vest 20% each year until fully vested. The right to exercise each such 20% of the options is cumulative and will not expire until the tenth anniversary of the date of the grant. All employees are eligible to participate in the 2020 plan if the Executive/Long-Range Committee, in its sole discretion, determines that such person has contributed or can be expected to contribute to our profits or growth. With respect to Executive Officers, the Executive/ Long-Range Planning Committee will obtain approval from the Compensation Committee for any options granted to them.

Option awards are generally granted with an exercise price equal to the market price of the Company’s common stock at the date of grant. The fair value of each option award is estimated on the date of grant using a closed form option valuation (Black-Scholes) model that uses the assumptions noted in the table below. Expected volatilities are based on historical volatilities of our common stock. The expected term of the options granted shall not exceed ten years from the date of grant (the amount of time options granted are expected to be outstanding). The risk-free interest rate for the expected term of the option is based on the U.S. Treasury yield curve in effect at the time of the grant.

The fair value of options granted was determined using the following weighted-average assumptions as of grant date:

	2020			2019			2018
Risk free interest rate		0.63	%		2.01	%		2.88	%
Expected life (in years)		7.5			7.5			7.5
Expected stock price volatility		32.90	%		33.13	%		33.69	%
Dividend yield		4.26	%		4.28	%		3.61	%

15. EMPLOYEE STOCK OWNERSHIP PLAN AND TRUST

We established an Employee Stock Ownership Plan (“ESOP”) effective January 1, 1989. Any employee of the Bank is eligible to become a participant in the ESOP upon reaching 21 years of age and credited with one-year of service (1,000 hours of service). The employee may enter the Plan on the January 1^st that occurs nearest the date on which the employee first satisfies the age and service requirements described above. No contributions by employees are permitted. The amount and time of contributions are at the sole discretion of the Board of Directors of the Bank. The contribution for all participants is based solely on each participant’s respective regular or base salary and wages paid by the Bank including commissions, bonuses and overtime, if any.

The Company recognizes expense when the contribution is approved by the Board of Directors. The total expenses amounted to $540,000, $510,000, and $420,000, during the years ended December 31, 2020, 2019, and 2018, respectively. As of December 31, 2020, the plan owned 344,384 shares of common stock of the Company.

A participant vests in the ESOP based upon the participant’s credited years of service. The vesting schedule is as follows:

●	1 Year of Service	0% Vested
●	2 Years of Service	25% Vested
●	3 Years of Service	50% Vested
●	4 Years of Service	75% Vested
●	5 Years of Service	100% Vested

Periodically, the Internal Revenue Service “IRS” requires a restatement of a qualified retirement plan to ensure that the plan document includes provisions required by legislative and regulatory changes made since the last restatement. There have been no substantive changes to the plan. The Board of Directors approved a restated plan, on January 26, 2012 (incorporated as Exhibit 10.5 in the 2011 10-K). The Plan was submitted to the IRS for approval and a determination letter was issued September 26, 2013, stating that the plan satisfies the requirements of Code Section 4975(e)(7). On January 26, 2017, the Board of Directors approved a restated plan (incorporated as Exhibit 10.6 in the 2016 10-K). The Plan was submitted to the IRS for approval and a determination letter was issued November 17, 2017, stating that the plan satisfies the requirements of Code Section 4975(e)(7).

16. DIVIDENDS

The Bank’s ability to pay dividends to the Company is restricted by the laws and regulations of the State of South Carolina. Generally, these restrictions allow the Bank to pay dividends from current earnings without the prior written consent of the South Carolina Commissioner of Banking, if it received a satisfactory rating at its most recent examination. Cash dividends when declared, are paid by the Bank to the Company for distribution to shareholders of the Company. The Bank paid dividends of $4.7 million, $4.2 million and $3.8 million, to the Company during the years ended December 31, 2020, 2019 and 2018, respectively.

17. Income Per Common Share

Basic income per share is computed by dividing net income by the weighted-average number of common shares outstanding. Diluted income per share is computed by dividing net income by the weighted-average number of common shares and potential common shares outstanding. Potential common shares consist of dilutive stock options determined using the treasury stock method and the average market price of common stock.

The following table is a summary of the reconciliation of average shares outstanding for the years ended December 31.

18. Regulatory Capital Requirements

The Company and the Bank are subject to various capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possible additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company and the Bank’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Bank must meet specific capital guidelines that involve quantitative measures of the 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 judgements by the regulators about components, risk weightings, and other factors.

Current quantitative measures established by regulation to ensure capital adequacy require that we maintain minimum amounts and ratios (set forth in the table below) of total and Tier 1 capital (as defined in the regulation) to risk-weighted assets (as defined) and to average assets. We believe that the Company and the Bank meet all capital adequacy requirements to which they were subject at December 31, 2020 and 2019.

On July 2, 2013, the Federal Reserve Board approved the final rules implementing the Basel Committee on Banking Supervision’s (“BCBS”) capital guidelines for U.S. banks (“Basel III”). Following the actions by the Federal Reserve, the FDIC also approved regulatory capital requirements on July 9, 2013. The FDIC’s rule is identical in substance to the final rules issued by the Federal Reserve Bank.

Basel III became effective on January 1, 2015. The purpose is to improve the quality and increase the quantity of capital for all banking organizations. The minimum requirements for the quantity and quality of capital were increased. The rule includes a new common equity Tier 1 capital to risk-weighted assets ratio of 4.50% and a common equity Tier 1 capital conservation buffer of 2.50% of risk-weighted assets. The rule also raises the minimum ratio of Tier 1 capital to risk-weighted assets from 4.00% to 6.00% and requires a minimum leverage ratio of 4.00%. In addition, the rule also implements strict eligibility criteria for regulatory capital instruments and improves the methodology for calculating risk-weighted assets to enhance risk sensitivity. All final rule requirements will be phased in over a multi-year schedule.

The following tables present the actual and required capital amounts and ratios for the Company and Bank at December 31, 2019:

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

On November 4, 2019, the federal banking agencies jointly issued a final rule on an optional, simplified measure of capital adequacy for qualifying community banking organizations called the community bank leverage ratio (“CBLR”) framework effective on January 1, 2020. A qualifying community banking organization is defined as having less than $10 billion in total consolidated assets, a leverage ratio greater than 9%, off-balance sheet exposures of 25% or less of total consolidated assets, and trading assets and liabilities of 5% or less of total consolidated assets. Additionally, the qualifying community banking institution must be a non-advanced approaches FDIC supervised institution. The final rule adopts Tier 1 capital and existing leverage ratio into the CBLR framework. The Bank adopted this rule as of September 30, 2020 and will no longer be subject to other capital and leverage requirements. Under the CBLR framework, a qualifying community banking organization is deemed to have met the “well capitalized” ratio requirements and be in appliance with the generally applicable capital rule.

The following table presents the actual CBLR for the Bank and Company at:

	December 31, 2020			December 31, 2019
Bank		10.19	%		11.23	%
Company		10.72	%		11.44	%

19. Disclosures Regarding Fair Value of Financial Instruments

Fair value measurements apply whenever GAAP requires or permits assets or liabilities to be measured at fair value either on a recurring or nonrecurring basis. Fair value is the price that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market in an orderly transaction between market participants at the measurement date. An orderly transaction is a transaction that assumes exposure to the market for a period prior to the measurement date to allow for marketing activities that are usual and customary for transactions involving such assets or liabilities; it is not a forced transaction. GAAP establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs. Observable inputs, which are developed based on market data we have obtained from independent sources, are ones that market participants would use in pricing an asset or liability. Unobservable inputs, which are developed based on the best information available in the circumstances, reflect our estimate of assumptions that market participants would use in pricing an asset or liability.

The fair value hierarchy gives the highest priority to unadjusted quoted market prices in active markets for identical assets or liabilities (Level 1 measurement) and the lowest priority to unobservable inputs (Level 3 measurement). The fair value hierarchy is broken down into three levels based on the reliability of inputs as follows:

● Level 1: valuation is based upon unadjusted quoted market prices for identical instruments traded in active markets.

● Level 2: valuation is based upon quoted market prices for similar instruments traded in active markets, quoted market prices for identical or similar instruments traded in markets that are not active and model-based valuation techniques for which all significant assumptions are observable in the market or can be corroborated by market data.

● Level 3: valuation is derived from other valuation methodologies, including discounted cash flow models and similar techniques that use significant assumptions not observable in the market. These unobservable assumptions reflect estimates of assumptions that market participants would use in determining fair value.

Fair value estimates are made at a specific point of time, based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale our entire holdings of a particular financial instrument. Because no active market exists for a significant portion of our financial instruments, fair value estimates are based on judgements 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 judgement and therefore cannot be determined with precision. Changes in any of these assumptions used in calculating fair value would also significantly affect the estimates. 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 following paragraphs describe the valuation methodologies used for assets and liabilities recorded at fair value on a recurring basis:

Investment Securities Available for Sale

Investment securities are recorded at fair value on a recurring basis and are based upon quoted prices if available. If quoted prices are not available, fair value is measured using independent pricing models or other model-based valuation techniques such as the present value of future cash flows, adjusted for the security’s credit rating, prepayment assumptions and other factors such as credit loss assumptions. Level 1 securities include those traded on an active exchange such as the New York Stock Exchange, or by dealers or brokers in active over-the counter markets. Level 2 securities include mortgage backed securities issued by government sponsored entities, municipal bonds and corporate debt securities. Securities classified as Level 3 include asset-backed and municipal securities in less liquid markets.

Derivative Instruments

Derivative instruments include interest rate lock commitments and forward sale commitments. These instruments are valued based on the change in the value of the underlying loan between the commitment date and the end of the period. We classify these instruments as Level 3.

We had no embedded derivative instruments requiring separate accounting treatment. We had freestanding derivative instruments consisting of fixed rate conforming loan commitments with interest rate locks and commitments to sell fixed rate conforming loans on a best efforts basis. We do not currently engage in hedging activities. Based on the short-term fair value of mortgage loans held for sale (derivative contract), our derivative instruments were immaterial to our consolidated financial statements as of December 31, 2020 and 2019.

The following paragraphs describe the valuation methodologies used for assets and liabilities recorded at fair value on a nonrecurring basis:

Impaired Loans

Impaired loans are carried at the lower of recorded investment or fair value. The fair value of the collateral less estimated costs to sell is the most frequently used method. Typically, we review the most recent appraisal and, if it is over 12 to 18 months old, we may 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, we 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 our primary market area, we 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.

 61

BANK OF SOUTH CAROLINA CORPORATION 

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

However, as a second example, on a nonperforming commercial real estate loan where we are familiar with the property and surrounding areas and where the original appraisal value far exceeds the recorded investment in the loan, we may perform an internal analysis whereby the previous appraisal value would be reviewed considering recent current conditions, and known recent sales or listings of similar properties in the area, and any other relevant economic trends. This analysis may result in the call for a new appraisal. These valuations are reviewed and updated on a quarterly basis.

In accordance with ASC 820, Fair Value Measurement, impaired loans, where an allowance is established based on the fair value of collateral, require classification in the fair value hierarchy. These impaired loans are classified as Level 3. Impaired loans measured using discounted future cash flows are not deemed to be measured at fair value.

Mortgage Loans to be Sold

Mortgage loans to be sold carried at the lower of cost or market value. The fair values of mortgage loans to be sold are based on current market rates from investors within the secondary market for loans with similar characteristics. Carrying value approximates fair value. These loans are classified as Level 2.

Certain assets and liabilities are measured at fair value on an ongoing basis; that is, the instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment). The following tables present information about certain assets and liabilities measured at fair value on a nonrecurring basis at December 31, 2020 and 2019.

BANK OF SOUTH CAROLINA CORPORATION 

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Accounting standards require disclosure of fair value information for all of our assets and liabilities that are considered financial instruments, whether or not recognized on the balance sheet, for which it is practicable to estimate fair value.

Under the accounting standard, fair value estimates are based on existing financial instruments without attempting to estimate the value of anticipated future business and the value of the assets and liabilities that are not financial instruments. Accordingly, the aggregate fair value amounts of existing financial instruments do not represent the underlying value of those instruments on our books.

The following paragraphs describe the methods and assumptions we use in estimating the fair values of financial instruments:

a. Cash and due from banks, interest-bearing deposits at the Federal Reserve Bank

The carrying value approximates fair value. All mature within 90 days and do not present unanticipated credit concerns.

b. Investment securities available for sale 

Investment securities available-for-sale are recorded at fair value on a recurring basis. Fair value measurement is based upon quoted prices, if available. If quoted prices are not available, fair values are measured using independent pricing models or other model-based valuation techniques such as the present value of future cash flows, adjusted for the security’s credit rating, prepayment assumptions and other factors such as credit loss assumptions.

c. Loans 

The fair value of the Company’s loan portfolio includes a credit risk assumption in the determination of the fair value of its loans. This 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: variable rate loans, impaired loans and all other loans. The results are then adjusted to account for credit risk as described above. However, under the new guidance, the Company believes 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. Additionally, in accordance with ASU 2016-01, Recognition and Measurement of Financial Assets and Liabilities, 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. Fair values for impaired loans are estimated using discounted cash flow models or based on the fair value of the underlying collateral.

d. Deposits 

The estimated fair value of deposits with no stated maturity is equal to the carrying amount. The fair value of time deposits is estimated by discounting contractual cash flows, using interest rates currently being offered on the deposit products. The fair value estimates for deposits do not include the benefit that results from the low cost funding provided by the deposit liabilities as compared to the cost of alternative forms of funding (deposit base intangibles).

e. Accrued interest receivable and payable 

Since these financial instruments will typically be received or paid within three months, the carrying amounts of such instruments are deemed a reasonable estimate of fair value.

f. Loan commitments 

Estimates of the fair value of these off-balance sheet items are not made because of the short-term nature of these arrangements and the credit standing on the counterparties.

The following tables present the carrying amount, fair value, and placement in the fair value hierarchy of our financial instruments as of December 31, 2020 and 2019, respectively.

Item 9. Changes In and Disagreements With Accountants on Accounting and Financial Disclosure

None

Item 9A. Controls and Procedures

An evaluation of the Company’s disclosure controls and procedures (as defined in Rule 13a-15(e) and Rule 15d-15(e) promulgated under the Securities and Exchange Act of 1934 as amended (the “Act”) was carried out as of December 31, 2020 under the supervision and with the participation of the Bank of South Carolina Corporation’s management, including its President/Chief Executive Officer and the Chief Financial Officer/Executive Vice President and several other members of the Company’s senior management. Based upon that evaluation, Bank of South Carolina Corporation’s management, including the President/Chief Executive Officer and the Chief Financial Officer/Executive Vice President concluded that, as of December 31, 2020, the Company’s disclosure controls and procedures were effective in ensuring that the information the Company is required to disclose in the reports filed or submitted under the Act has been (i) accumulated and communicated to management (including the President/Chief Executive Officer and Chief Financial Officer/Executive Vice President) to allow timely decisions regarding required disclosure, and (ii) recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms.

Management’s Report on Internal Control Over Financial Reporting

The Company’s management is responsible for establishing and maintaining adequate internal controls over financial reporting, as such term is defined in Rule 13a-15(f) of the Exchange Act. The Company’s internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of published financial statements in accordance with generally accepted accounting principles.

Under the supervision and with the participation of management, including the President/Chief Executive Officer and the Chief Financial Officer/Executive Vice President, the Company’s management has evaluated the effectiveness of its internal control over financial reporting as of December 31, 2020, based on the 2013 framework established in a report entitled “Internal Control-Integrated Framework” issued by the Committee of Sponsoring Organizations of the Treadway Commission.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

The Company’s management assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2020. Based on this assessment, management believes that as of December 31, 2020, the Company’s internal control over financial reporting was effective. There were no changes in the Company’s internal control over financial reporting that occurred during the year ended December 31, 2020, that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

This annual report does not include an attestation report of the Company’s registered public accounting firm regarding internal control over financial reporting. Management’s report is not subject to attestation by the Company’s registered public accounting firm pursuant to the final ruling by the Securities and Exchange Commission that permit the Company to provide only management’s report in its annual report.

The Audit and Compliance Committee, composed entirely of independent Directors, meets periodically with management, the Company’s Audit & Compliance Officer, and Elliott Davis, LLC (separately and jointly) to discuss audit, financial and related matters. Elliott Davis, LLC and the Audit & Compliance Officer have direct access to the Audit and Compliance Committee.

Accounting Policies [Abstract]

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Our accounting and reporting policies conform, in all material respects, to U.S. generally accepted accounting principles (“GAAP”), and to general practices within the banking industry. The following summarizes the more significant of these policies and practices.

Principles of Consolidation:  

The accompanying consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary, the Bank. In consolidation, all significant intercompany balances and transactions have been eliminated.

References to “we,” “us,” “our,” “the Bank,” or “the Company” refer to the parent and its subsidiary that are consolidated for financial purposes.

Accounting Estimates and Assumptions:  

The financial statements are prepared in conformity with GAAP, which require management to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reported periods. Actual results could differ significantly from these estimates and assumptions. Material estimates generally susceptible to significant change are related to the determination of the allowance for loan losses, impaired loans, other real estate owned, deferred tax assets, the fair value of financial instruments and other-than-temporary impairment of investment securities.

Reclassification:  

Certain amounts in the prior years’ financial statements have been reclassified to conform to the current year’s presentation. Such reclassifications have no effect on shareholders’ equity or the net income as previously reported.

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 as of the date of the balance sheet, including the estimates inherent in the process of preparing financial statements. Non-recognized subsequent events are events that provide evidence about conditions that did not exist as of the date of the balance sheet but arose after that date. We have reviewed events occurring through the date the financial statements were available to be issued and no subsequent events occurred requiring accrual or disclosure.

Cash and Cash Equivalents:  

Cash and cash equivalents include working cash funds, due from banks, interest-bearing deposits at the Federal Reserve, items in process of collection and federal funds sold. All cash equivalents are readily convertible to cash and have maturities of less than 90 days.

Depository institutions are required to maintain reserve and clearing balances at the Federal Reserve Bank. Vault cash satisfied our daily reserve requirement for the years ended December 31, 2020 and 2019, respectively.  

Interest-bearing Deposits at the Federal Reserve:  

Interest-bearing deposits at the Federal Reserve mature daily and are carried at cost.

Investment Securities:  

We classify investments into three categories: (1) Held to Maturity - debt securities that we have the positive intent and ability to hold to maturity, which are reported at amortized cost, adjusted for the amortization of any related premiums or the accretion of any related discounts into interest income using a methodology which approximates a level yield of interest over the estimated remaining period until maturity; (2) Trading - debt and equity securities that are bought and held principally for the purpose of selling them in the near term, which are reported at fair value, with unrealized gains and losses included in earnings; and (3) Available for Sale - debt and equity securities that may be sold under certain conditions, which are reported at fair value, with unrealized gains and losses excluded from earnings and reported as a separate component of shareholders’ equity, net of income taxes. Unrealized losses on securities due to fluctuations in fair value are recognized when it is determined that an other than temporary decline in value has occurred.

Realized gains or losses on the sale of investments are recognized on a specific identification, trade date basis. All securities were classified as available for sale for 2020 and 2019.

Mortgage Loans to be Sold:  

We originate fixed and variable rate residential mortgage loans on a service release basis in the secondary market. Loans closed but not yet settled with an investor are carried in our loans held for sale portfolio.   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 our customers.  Therefore, these loans present very little market risk.  We usually deliver to, and receive funding from, the investor within 30 to 60 days.  Commitments to sell these loans to the investor are considered derivative contracts and are sold to investors on a “best efforts” basis. We are not obligated to deliver a loan or pay a penalty if a loan is not delivered to the investor. Because of the short-term nature of these derivative contracts, the fair value of the mortgage loans held for sale in most cases is materially the same as the value of the loan amount at its origination.

Mortgage loans originated and intended for sale in the secondary market are carried at the lower of cost or estimated market value in the aggregate. Net unrealized losses are provided for in a valuation allowance by charges to operations as a component of mortgage banking income. Gains or losses on sales of loans are recognized when control over these assets are surrendered and are included in mortgage banking income in the consolidated statements of income.

Loans and Allowance for Loan Losses:   

Loans are carried at principal amounts outstanding. Loan origination fees, net of certain direct origination costs, are deferred and recognized over the weighted average life of the loan as an adjustment to yield. Interest income on all loans is recorded on an accrual basis. The accrual of interest and the amortization of net loan fees are generally discontinued on loans that 1) are maintained on a cash basis because of deterioration in the financial condition of the borrower; 2) the payment of full principal is not expected; or 3) the principal or interest has been in default for a period of 90 days or more. We define past due loans based on contractual payment and maturity dates.

The accrual of interest is generally discontinued on loans that become 90 days past due as to principal or interest. The accrual of interest on some loans may continue even though they are 90 days past due if the loans are well secured or in the process of collection and management deems it appropriate. If non-accrual loans decrease their past due status to less than 30 days for a period of six to nine months, they are reviewed individually by management to determine if they should be returned to accrual status.

When the ultimate collectability of an impaired loan’s principal is in doubt, wholly or partially, all cash receipts are applied 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. When this doubt does not exist, cash receipts are applied under the contractual terms of the loan agreement first to interest income and then to principal.  

We account for impaired loans by requiring that all loans (greater than $50,000) where it is estimated that we will be unable to collect all amounts due according to the terms of the loan agreement be recorded at the loan’s fair value. Fair value may be determined based upon the present value of expected future cash flows discounted at the loan’s effective interest rate, or the fair value of the collateral less cost to sell, if the loan is collateral dependent.

Additional accounting guidance allows us to use existing methods for recognizing interest income on an impaired loan. The guidance also requires additional disclosures about how we estimate interest income related to our impaired loans.

A loan is also considered impaired if its terms are modified in a troubled debt restructuring (“TDR”). For this type of impaired loan, cash receipts are typically applied to principal and interest receivable in accordance with the terms of the restructured loan agreement. Interest income is recognized on these loans using the accrual method of accounting, provided they are performing in accordance with their restructured terms.

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

We believe that the allowance is adequate to absorb inherent losses in the loan portfolio; however, there can be no assurance that loan losses in future periods will not exceed the current allowance amount or that future increases in the allowance will not be required. No assurance can be given that our ongoing evaluation of the loan portfolio, in light of changing economic conditions and other relevant circumstances, will not require significant future additions to the allowance, thus adversely affecting our operating results.

The allowance is also subject to examination by regulatory agencies, which may consider factors such as the methodology used to determine adequacy and the size of the allowance relative to that of peer institutions and other adequacy tests. In addition, such regulatory agencies could require us to adjust our allowance based on information available at the time of the examination.

The methodology used to determine the reserve for unfunded lending commitments, which is included in other liabilities, is inherently similar to the methodology used to determine the allowance adjusted for factors specific to binding commitments, including the probability of funding and historical loss ratio.

Concentration of Credit Risk:  

Our primary market consists of the counties of Berkeley, Charleston and Dorchester, South Carolina. As of December 31, 2020, the majority of the total loan portfolio, as well as a substantial portion of the commercial and real estate loan portfolios, were to borrowers within this region. No other areas of significant concentration of credit risk have been identified.

Premises, Equipment and Leasehold Improvements and Depreciation:  

Land is carried at cost. Buildings and equipment are stated at cost less accumulated depreciation. Depreciation is recorded using the straight-line method for financial reporting purposes and accelerated methods for income tax purposes over the estimated useful lives of the assets ranging from 40 years for buildings and 3 to 15 years for equipment. Leasehold improvements are amortized over the shorter of the asset’s useful life or the remaining lease term, including renewal periods when reasonably assured. The cost of maintenance and repairs is charged to operating expense as incurred.

Leases:

In accordance with ASU 2016-02, the Company determines if a contractual arrangement is a lease at inception. Operating leases are included in the operating right of use (“ROU”) assets and current operating lease liabilities on the Company’s Consolidated Balance Sheet. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Currently, the Company does not have any finance leases.

Beginning January 1, 2019, operating lease ROU assets and lease liabilities are recognized at the commencement of the lease based on the present value of lease payments over the lease term. The lease payments included in the present value are fixed payments and index-based variable lease payments. The Company estimates the incremental borrowing rate, based on information available at the commencement of the lease, as most of the Company’s leases do not include an implicit rate.

Income Taxes:  

We account for income taxes under the asset and liability method. Deferred tax assets and liabilities are recognized for future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using the enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Net deferred tax assets are included in other assets in the consolidated balance sheet.

Accounting standards require the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements. These standards also prescribe a recognition threshold and measurement of a tax position taken or expected to be taken in an enterprise’s tax return. We believe that we had no uncertain tax positions for the years ended December 31, 2020 and 2019.

Stock-Based Compensation:  

Compensation cost is recognized for stock options issued to employees, based on the fair value of these awards at the date of grant. A Black-Scholes model is utilized to estimate the fair value of stock options. Compensation cost is recognized over the required expected term, generally defined as the average vesting period (7.5 years).

Income Per Common Share:  

Basic income per share is computed by dividing net income by the weighted-average number of common shares outstanding. Diluted earnings per share is computed by dividing net income by the weighted-average number of common shares and potential common shares outstanding. Potential common shares consist of dilutive stock options determined using the treasury stock method and the average market price of common stock. Earnings per share are restated for all stock splits and stock dividends through the date of issuance of the financial statements.

Segment Information:  

The Company operates and manages itself within one retail banking segment and therefore has not provided segment disclosures.

Interest Rate Lock Commitments and Forward Sale Contracts:  

Commitments to fund mortgage loans (interest rate locks) to be sold into the secondary market and forward commitments for the future delivery of these mortgage loans are accounted for as free-standing derivatives. The fair value of the interest rate lock is recorded at the time the commitment to fund the mortgage loan is executed and is adjusted for the expected exercise of the commitments before the loan is funded. In order to hedge the change in interest rates resulting from commitments to fund the loans, we enter into forward commitments for the future delivery of mortgage loans when the interest rate is locked. Fair values of these mortgage derivatives are estimated based on changes in mortgage interest rates from the date the interest on the loan is locked. Changes in the fair values of these derivatives are included in income when they occur. As a result of the short-term nature of mortgage loans held for sale (derivative contract), our derivative instruments were considered to be immaterial as of December 31, 2020 and 2019.

We had no embedded derivative instruments requiring hedge accounting treatment at December 31, 2020. We do not currently engage in hedging activities.

Recent Accounting Pronouncements:  

The following is a summary of recent authoritative pronouncements that could impact the accounting, reporting and/or disclosure of financial information by the Company.

In June 2016, the FASB issued ASU 2016-13, Financial instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, to change the accounting for credit losses and modify the impairment model for certain debt securities. In May 2019, the FASB issued guidance to provide entities with an option to irrevocably elect the fair value option, applied on an instrument-by-instrument basis for eligible instruments, upon adoption of ASU 2016-13, Measurement of Credit Losses on Financial Instruments. In October 2019, the FASB voted to extend the implementation date for smaller reporting companies, non-SEC public companies, and private companies. On March 27, 2020, the Board of Governors of the Federal Reserve, FDIC, and Office of the Comptroller of Currency announced the interim final rule allowing banks to delay the effects of CECL until 2022 for filers scheduled to implement in 2020 and 2023 for all other filers. This amendment will become effective for the Company on January 1, 2023. The Company is currently evaluating the effect that implementation of the new standard will have on its financial position, results of operations, and cash flows. It will be influenced by the quality, composition, and characteristics of our loan and investment portfolios, as well as the expected economic conditions and forecasts at the time of enactment and future reporting periods.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement. The amendments remove, modify, and add certain fair value disclosure requirements based on the concepts in the FASB Concepts Statement, Conceptual Framework for Financial Reporting—Chapter 8: Notes to Financial Statements. The amendment became effective for the Company on January 1, 2020 and did not have a material effect on the financial statements.

The amendments became effective for the Company on January 1, 2020 and did not have a material effect on the financial statements.

In October 2018, the FASB issued ASU 2018-07, Consolidation (Topic 810): Targeted Improvements to Related Party Guidance for Variable Interest Entities, determining whether a decision-making fee is a variable interest.

The tables below summarize gross unrealized losses on investment securities and the fair market value of the related securities, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position, at December 31, 2020 and 2019. We believe that all unrealized losses have resulted from temporary changes in the interest rate market and not as a result of credit deterioration. We do not intend to sell and it is not likely that we will be required to sell any of the securities referenced in the table below before recovery of their amortized cost.

We had $76.0 million and $85.2 million of loans pledged as collateral to secure funding with the Federal Reserve Bank (“FRB”) Discount Window at December 31, 2020 and 2019, respectively.

On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) was signed into law, which established the Paycheck Protection Program (“PPP”) and allocated $349.0 billion of loans to be issued by financial institutions. Under the program, the Small Business Administration (“SBA”) will forgive loans, in whole or in part, made by approved lenders to eligible borrowers for payroll and other permitted purposes in accordance with the requirements of the program. These loans carry a fixed rate of 1.00% and a term of two years, if not forgiven, in whole or in part. The loans are 100% guaranteed by the SBA and as long as the borrower submits its loan forgiveness application within ten months of completion of the covered period, the borrower is not required to make any payments until the forgiveness amount is remitted to the lender by the SBA. The Bank received a processing fee ranging from 1% to 5% based on the size of the loan from the SBA. The fees are deferred and amortized over the life of the loans in accordance with ASC 310-20. The Bank received processing fees of $1.4 million and recognized $0.6 million during the year ended December 31, 2020. The Paycheck Protection Program and Health Care Enhancement Act (“PPP/ HCEA Act”) was signed into law on April 24, 2020. The PPP/HCEA Act authorized additional funding under the CARES Act of $310.0 billion for PPP loans to be issued by financial institutions through the SBA. The Bank provided $37.8 million in funding to 266 customers through the PPP as of December 31, 2020. Because these loans are 100% guaranteed by the SBA and did not undergo the Bank’s typical underwriting process, they are not graded and do not have an associated reserve. 

Our portfolio grading analysis estimates the capability of the borrower to repay the contractual obligations of the loan agreements as scheduled. Our internal credit risk grading system is based on experience with similarly graded loans, industry best practices, and regulatory guidance. Our portfolio is graded in its entirety, with the exception of the PPP loans.

Our internally assigned grades pursuant to the Board-approved lending policy are as follows:

● Excellent (1) The borrowing entity has more than adequate cash flow, unquestionable strength, strong earnings and capital, and where applicable, no overdrafts.

● Good (2) The borrowing entity has dependable cash flow, better than average financial condition, good capital and usually no overdrafts.

● Satisfactory (3) The borrowing entity has adequate cash flow, satisfactory financial condition, and explainable overdrafts (if any).

● Watch (4) The borrowing entity has generally adequate, yet inconsistent cash flow, cyclical earnings, weak capital, loan to/from stockholders, and infrequent overdrafts. The borrower has consistent yet sometimes unpredictable sales and growth.

● OAEM (5) The borrowing entity has marginal cash flow, occasional past dues, and frequent and unexpected working capital needs.

● Substandard (6) The borrowing entity has cash flow barely sufficient to service debt, deteriorated financial condition, and bankruptcy is a possibility. The borrowing entity has declining sales, rising costs, and may need to look for secondary source of repayment.

● Doubtful (7) The borrowing entity has negative cash flow. Survival of the business is at risk, full repayment is unlikely, and there are frequent and unexplained overdrafts. The borrowing entity shows declining trends and no operating profits.

● Loss (8) The borrowing entity has negative cash flow with no alternatives. Survival of the business is unlikely.

The following tables illustrate credit risks by category and internally assigned grades at December 31, 2020 and 2019. “Pass” includes loans internally graded as excellent, good and satisfactory.

In general, the modification or restructuring of a debt is considered a troubled debt restructuring (“TDR”) if we, for economic or legal reasons related to a borrower’s financial difficulties, grant a concession to the borrower that we would not otherwise consider. As of December 31, 2020, there were 14 TDRs with a balance of $5.8 million. As of December 31, 2019, there were 3 TDRs with a balance of $573,473. These TDRs were granted extended payment terms with no principal reduction. The structure of two of the loans changed to interest only. All TDRs were performing as agreed as of December 31, 2020. During the year ended December 31, 2019, one TDR in the amount of $2,008 was charged off and the Company recovered $439. No other TDRs that were modified within the previous twelve months defaulted during the following year for the years ended December 31, 2020, 2019, and 2018.

Regulatory agencies, as set forth in the Interagency Statement on Loan Modifications and Reporting for Financial Institutions Working with Customers Affected by the Coronavirus (initially issued on March 22, 2020 and revised on April 7, 2020), have encouraged financial institutions to work prudently with borrowers who are or may be unable to meet their contractual payment obligations because of the effects of COVID-19. In this statement, the regulatory agencies expressed their view of loan modification programs as positive actions that may mitigate adverse effects on borrowers due to COVID-19 and that the agencies will not criticize institutions for working with borrowers in a safe and sound manner. Moreover, the revised statement provides that eligible loan modifications related to COVID-19 may be accounted for under section 4013 of the CARES Act or in accordance with ASC 310-40. Under Section 4013 of the CARES Act, banks may elect not to categorize loan modifications as TDRs if the modifications are related to COVID-19, executed on a loan that was not more than 30 days past due as of December 31, 2019, and executed between March 1, 2020 and the earlier of December 31, 2020 or 60 days after the date of termination of the National Emergency. All short-term loan modifications made on a good faith basis in response to COVID-19 to borrowers who were current prior to any relief are not considered TDRs. Beginning in March 2020, the Bank provided payment accommodations to customers, consisting of 60-day principal deferral to borrowers negatively impacted by COVID-19. The Bank processed approximately $0.7 million in principal deferments to 84 customers, with an aggregate loan balance of $25.9 million, during the year ended December 31, 2020. The principal deferments represent 0.24% of our total loan portfolio as of December 31, 2020. The Bank has examined the payment accommodations granted to borrowers in response to COVID-19 and classified 9 loans, with an aggregate loan balance of $4.0 million, that were granted payment accommodations as TDRs given the continued financial difficulty of the customer, associated industry risk, and multiple deferral requests. All other borrowers were current prior to relief, were not experiencing financial difficulty prior to COVID-19, and the Bank determined they were not considered TDRs. Additionally, of the 75 customers that received payment accommodations that are not classified as TDRs, 15 customers, with an aggregate loan balance of $2.9 million, have paid their loan in full, 7 customers, with an aggregate loan balance of $3.3 million, are past due less than 30 days, and 53 customers, with an aggregate loan balance of $18.6 million, have commenced paying as agreed as of December 31, 2020. There are no loans that received payment accommodation past due greater than 30 days. The Bank will continue to examine payment accommodations as requested by borrowers.

We grant short to intermediate term commercial and consumer loans to customers throughout our primary market area of Charleston, Berkeley and Dorchester counties of South Carolina. Our primary market area is heavily dependent on tourism, medical, and legal services. Although we have a diversified loan portfolio, a substantial portion of our debtors’ ability to honor their contracts is dependent upon the stability of the economic environment in their primary market. The majority of the loan portfolio is located in our immediate market area with a concentration in real estate related activities.

Our loans were concentrated in the following categories.

LEASES

7. LEASES

As of December 31, 2020, the Company had operating right of use (“ROU”) assets of $12.7 million and operating lease liabilities of $12.7 million. The Company maintains operating leases on land, branch facilities, and parking. Most of the leases include one or more options to renew, with renewal terms extending up to 20 years. Leases with an initial term of 12 months or less are not recorded on the balance sheet and are recognized in lease expense.

The weighted average remaining lease term is 17.6 years. The weighted average incremental borrowing rate is 4.35%.

The exercise of renewal options is based on the sole judgement of management and what they consider to be reasonably certain. Based on the market areas, past practices, and contract terms of all leases, the Bank assumed all renewal options will be exercised. Minimum rental commitments for these leases as of December 31, 2020 are presented in the table below.

2021	$	1,043,404

On December 22, 2017, the President of the United States signed into law the 2017 Tax Act. The 2017 Tax Act included a number of changes to the existing U.S. tax laws that impact the Company, most notably a reduction in the U.S. corporate income tax rate from 34 percent to 21 percent for tax years beginning after December 31, 2017.

Total income taxes for the years ended December 31, 2020, 2019 and 2018 are presented in the table below.

In 2018, the Company invested in a Federal Rehabilitation Credit. The tax credit was used during the year ended December 31, 2018. Amortization expense recognized for the years ended December 31, 2019 and 2018 was $8,022 and $354,888, respectively. In 2016, the Company invested in a South Carolina Rehabilitation Credit. The tax credit was included in deferred tax assets and is being amortized. Amortization expense recognized for the year ended December 31, 2018 was $306,105 and was included in other operating expense on the statement of operations.

There was a $89,997 and $81,914 valuation allowance for deferred tax assets at December 31, 2020 and 2019, respectively, associated with the Company’s state tax credits. In assessing the realization of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred income tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible and prior to their expiration governed by the income tax code. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and tax planning strategies in making this assessment. Based upon the level of historical taxable income and projections for future taxable income over the periods during which the deferred income tax assets are expected to be deductible, management believes it is more likely than not the Company will realize the benefits of these deductible differences, net of the existing valuation allowance at December 31, 2020. The amount of the deferred income tax asset considered realizable, however, could be reduced in the near term if estimates of future taxable income during the carry forward period are reduced.

The Company measures deferred tax assets and liabilities using enacted tax rates that will apply in the years in which the temporary differences are expected to be recovered or paid.

The Company has analyzed the tax positions taken or expected to be taken in its tax returns and concluded it has no liability related to uncertain tax positions in accordance with applicable regulations.

Tax returns for 2017 and subsequent years are subject to examination by taxing authorities.

COMMITMENTS AND CONTINGENCIES

11. Commitments and Contingencies

We are a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of our customers. These financial instruments include commitments to extend credit and standby letters of credit. Those instruments involve, to varying degrees, elements of credit, interest rate, and liquidity risk. Our exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit and standby letters of credit is essentially the same as that involved in extending loan facilities to customers. We use the same credit policies in making commitments and conditional obligations as we do for on-balance sheet instruments.

Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. If deemed necessary, the amount of collateral obtained upon extension of credit is based on our credit evaluation of the borrower. Collateral held varies, but may include accounts receivable, negotiable instruments, inventory, property, plant and equipment, and real estate. Commitments to extend credit, including unused lines of credit, amounted to $122,755,761 and $105,481,545 at December 31, 2020 and 2019, respectively.

Standby letters of credit represent our obligation to a third-party contingent upon the failure by our customer to perform under the terms of an underlying contract with the third party or obligates us to guarantee or stand as surety for the benefit of the third party. The underlying contract may entail either financial or nonfinancial obligations and may involve such things as the shipment of goods, performance of a contract, or repayment of an obligation. Under the terms of a standby letter, generally drafts will be drawn only when the underlying event fails to occur as intended. We can seek recovery of the amounts paid from the borrower. Commitments under standby letters of credit are usually for one year or less. At December 31, 2020 and 2019, we have recorded no liability for the current carrying amount of the obligation to perform as a guarantor; as such amounts are not considered material. The maximum potential amount of undiscounted future payments related to standby letters of credit at December 31, 2020 and 2019 was $845,811 and $1,042,966, respectively.

Share-based Payment Arrangement [Abstract]

STOCK INCENTIVE PLAN

14. Stock Incentive Plan

We have two employee Stock Incentive Plans: the first plan, which was approved in 2010, has 300,000 (363,000 adjusted for two 10% stock dividends) shares reserved and the second plan, which was approved in 2020, has 300,000 shares reserved. No new options may be granted under the 2010 plan, as it expired on April 14, 2020. Under the 2020 plan, options are periodically granted to employees at a price not less than the fair market value of the shares at the date of grant. Employees become 20% vested after five years and then vest 20% each year until fully vested. The right to exercise each such 20% of the options is cumulative and will not expire until the tenth anniversary of the date of the grant. All employees are eligible to participate in the 2020 plan if the Executive/Long-Range Committee, in its sole discretion, determines that such person has contributed or can be expected to contribute to our profits or growth. With respect to Executive Officers, the Executive/ Long-Range Planning Committee will obtain approval from the Compensation Committee for any options granted to them.

Option awards are generally granted with an exercise price equal to the market price of the Company’s common stock at the date of grant. The fair value of each option award is estimated on the date of grant using a closed form option valuation (Black-Scholes) model that uses the assumptions noted in the table below. Expected volatilities are based on historical volatilities of our common stock. The expected term of the options granted shall not exceed ten years from the date of grant (the amount of time options granted are expected to be outstanding). The risk-free interest rate for the expected term of the option is based on the U.S. Treasury yield curve in effect at the time of the grant.

The fair value of options granted was determined using the following weighted-average assumptions as of grant date:

	2020			2019			2018
Risk free interest rate		0.63	%		2.01	%		2.88	%
Expected life (in years)		7.5			7.5			7.5
Expected stock price volatility		32.90	%		33.13	%		33.69	%
Dividend yield		4.26	%		4.28	%		3.61	%

Employee Stock Ownership Plan And Trust

EMPLOYEE STOCK OWNERSHIP PLAN AND TRUST

15. EMPLOYEE STOCK OWNERSHIP PLAN AND TRUST

We established an Employee Stock Ownership Plan (“ESOP”) effective January 1, 1989. Any employee of the Bank is eligible to become a participant in the ESOP upon reaching 21 years of age and credited with one-year of service (1,000 hours of service). The employee may enter the Plan on the January 1^st that occurs nearest the date on which the employee first satisfies the age and service requirements described above. No contributions by employees are permitted. The amount and time of contributions are at the sole discretion of the Board of Directors of the Bank. The contribution for all participants is based solely on each participant’s respective regular or base salary and wages paid by the Bank including commissions, bonuses and overtime, if any.

The Company recognizes expense when the contribution is approved by the Board of Directors. The total expenses amounted to $540,000, $510,000, and $420,000, during the years ended December 31, 2020, 2019, and 2018, respectively. As of December 31, 2020, the plan owned 344,384 shares of common stock of the Company.

A participant vests in the ESOP based upon the participant’s credited years of service. The vesting schedule is as follows:

●	1 Year of Service	0% Vested
●	2 Years of Service	25% Vested
●	3 Years of Service	50% Vested
●	4 Years of Service	75% Vested
●	5 Years of Service	100% Vested

Periodically, the Internal Revenue Service “IRS” requires a restatement of a qualified retirement plan to ensure that the plan document includes provisions required by legislative and regulatory changes made since the last restatement. There have been no substantive changes to the plan. The Board of Directors approved a restated plan, on January 26, 2012 (incorporated as Exhibit 10.5 in the 2011 10-K). The Plan was submitted to the IRS for approval and a determination letter was issued September 26, 2013, stating that the plan satisfies the requirements of Code Section 4975(e)(7). On January 26, 2017, the Board of Directors approved a restated plan (incorporated as Exhibit 10.6 in the 2016 10-K). The Plan was submitted to the IRS for approval and a determination letter was issued November 17, 2017, stating that the plan satisfies the requirements of Code Section 4975(e)(7).

16. DIVIDENDS

The Bank’s ability to pay dividends to the Company is restricted by the laws and regulations of the State of South Carolina. Generally, these restrictions allow the Bank to pay dividends from current earnings without the prior written consent of the South Carolina Commissioner of Banking, if it received a satisfactory rating at its most recent examination. Cash dividends when declared, are paid by the Bank to the Company for distribution to shareholders of the Company. The Bank paid dividends of $4.7 million, $4.2 million and $3.8 million, to the Company during the years ended December 31, 2020, 2019 and 2018, respectively.

REGULATORY CAPITAL REQUIREMENTS

REGULATORY CAPITAL REQUIREMENTS

18. Regulatory Capital Requirements

The Company and the Bank are subject to various capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possible additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company and the Bank’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Bank must meet specific capital guidelines that involve quantitative measures of the 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 judgements by the regulators about components, risk weightings, and other factors.

Current quantitative measures established by regulation to ensure capital adequacy require that we maintain minimum amounts and ratios (set forth in the table below) of total and Tier 1 capital (as defined in the regulation) to risk-weighted assets (as defined) and to average assets. We believe that the Company and the Bank meet all capital adequacy requirements to which they were subject at December 31, 2020 and 2019.

On July 2, 2013, the Federal Reserve Board approved the final rules implementing the Basel Committee on Banking Supervision’s (“BCBS”) capital guidelines for U.S. banks (“Basel III”). Following the actions by the Federal Reserve, the FDIC also approved regulatory capital requirements on July 9, 2013. The FDIC’s rule is identical in substance to the final rules issued by the Federal Reserve Bank.

Basel III became effective on January 1, 2015. The purpose is to improve the quality and increase the quantity of capital for all banking organizations. The minimum requirements for the quantity and quality of capital were increased. The rule includes a new common equity Tier 1 capital to risk-weighted assets ratio of 4.50% and a common equity Tier 1 capital conservation buffer of 2.50% of risk-weighted assets. The rule also raises the minimum ratio of Tier 1 capital to risk-weighted assets from 4.00% to 6.00% and requires a minimum leverage ratio of 4.00%. In addition, the rule also implements strict eligibility criteria for regulatory capital instruments and improves the methodology for calculating risk-weighted assets to enhance risk sensitivity. All final rule requirements will be phased in over a multi-year schedule.

The following tables present the actual and required capital amounts and ratios for the Company and Bank at December 31, 2019:

	December 31, 2019
	Actual					For Capital Adequacy Purposes					To Be Well Capitalized Under Prompt Corrective Action Provisions
(in thousands)	Amount		Ratio			Amount		Ratio			Amount		Ratio

Bank	$	49,860		15.23	%	$	14,737		4.50	%	$	14,737		4.50	%

On November 4, 2019, the federal banking agencies jointly issued a final rule on an optional, simplified measure of capital adequacy for qualifying community banking organizations called the community bank leverage ratio (“CBLR”) framework effective on January 1, 2020. A qualifying community banking organization is defined as having less than $10 billion in total consolidated assets, a leverage ratio greater than 9%, off-balance sheet exposures of 25% or less of total consolidated assets, and trading assets and liabilities of 5% or less of total consolidated assets. Additionally, the qualifying community banking institution must be a non-advanced approaches FDIC supervised institution. The final rule adopts Tier 1 capital and existing leverage ratio into the CBLR framework. The Bank adopted this rule as of September 30, 2020 and will no longer be subject to other capital and leverage requirements. Under the CBLR framework, a qualifying community banking organization is deemed to have met the “well capitalized” ratio requirements and be in appliance with the generally applicable capital rule.

The following table presents the actual CBLR for the Bank and Company at:

	December 31, 2020			December 31, 2019

DISCLOSURES REGARDING FAIR VALUE OF FINANCIAL INSTRUMENTS

Fair Value Disclosures [Abstract]

DISCLOSURES REGARDING FAIR VALUE OF FINANCIAL INSTRUMENTS

19. Disclosures Regarding Fair Value of Financial Instruments

Fair value measurements apply whenever GAAP requires or permits assets or liabilities to be measured at fair value either on a recurring or nonrecurring basis. Fair value is the price that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market in an orderly transaction between market participants at the measurement date. An orderly transaction is a transaction that assumes exposure to the market for a period prior to the measurement date to allow for marketing activities that are usual and customary for transactions involving such assets or liabilities; it is not a forced transaction. GAAP establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs. Observable inputs, which are developed based on market data we have obtained from independent sources, are ones that market participants would use in pricing an asset or liability. Unobservable inputs, which are developed based on the best information available in the circumstances, reflect our estimate of assumptions that market participants would use in pricing an asset or liability.

The fair value hierarchy gives the highest priority to unadjusted quoted market prices in active markets for identical assets or liabilities (Level 1 measurement) and the lowest priority to unobservable inputs (Level 3 measurement). The fair value hierarchy is broken down into three levels based on the reliability of inputs as follows:

● Level 1: valuation is based upon unadjusted quoted market prices for identical instruments traded in active markets.

● Level 2: valuation is based upon quoted market prices for similar instruments traded in active markets, quoted market prices for identical or similar instruments traded in markets that are not active and model-based valuation techniques for which all significant assumptions are observable in the market or can be corroborated by market data.

● Level 3: valuation is derived from other valuation methodologies, including discounted cash flow models and similar techniques that use significant assumptions not observable in the market. These unobservable assumptions reflect estimates of assumptions that market participants would use in determining fair value.

Fair value estimates are made at a specific point of time, based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale our entire holdings of a particular financial instrument. Because no active market exists for a significant portion of our financial instruments, fair value estimates are based on judgements 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 judgement and therefore cannot be determined with precision. Changes in any of these assumptions used in calculating fair value would also significantly affect the estimates. 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 following paragraphs describe the valuation methodologies used for assets and liabilities recorded at fair value on a recurring basis:

Investment Securities Available for Sale

Investment securities are recorded at fair value on a recurring basis and are based upon quoted prices if available. If quoted prices are not available, fair value is measured using independent pricing models or other model-based valuation techniques such as the present value of future cash flows, adjusted for the security’s credit rating, prepayment assumptions and other factors such as credit loss assumptions. Level 1 securities include those traded on an active exchange such as the New York Stock Exchange, or by dealers or brokers in active over-the counter markets. Level 2 securities include mortgage backed securities issued by government sponsored entities, municipal bonds and corporate debt securities. Securities classified as Level 3 include asset-backed and municipal securities in less liquid markets.

Derivative Instruments

Derivative instruments include interest rate lock commitments and forward sale commitments. These instruments are valued based on the change in the value of the underlying loan between the commitment date and the end of the period. We classify these instruments as Level 3.

We had no embedded derivative instruments requiring separate accounting treatment. We had freestanding derivative instruments consisting of fixed rate conforming loan commitments with interest rate locks and commitments to sell fixed rate conforming loans on a best efforts basis. We do not currently engage in hedging activities. Based on the short-term fair value of mortgage loans held for sale (derivative contract), our derivative instruments were immaterial to our consolidated financial statements as of December 31, 2020 and 2019.

There were no transfers between fair value levels during the year ended December 31, 2020 or 2019.

The following paragraphs describe the valuation methodologies used for assets and liabilities recorded at fair value on a nonrecurring basis:

Impaired Loans

Impaired loans are carried at the lower of recorded investment or fair value. The fair value of the collateral less estimated costs to sell is the most frequently used method. Typically, we review the most recent appraisal and, if it is over 12 to 18 months old, we may 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, we 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 our primary market area, we 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 we are familiar with the property and surrounding areas and where the original appraisal value far exceeds the recorded investment in the loan, we may perform an internal analysis whereby the previous appraisal value would be reviewed considering recent current conditions, and known recent sales or listings of similar properties in the area, and any other relevant economic trends. This analysis may result in the call for a new appraisal. These valuations are reviewed and updated on a quarterly basis.

In accordance with ASC 820, Fair Value Measurement, impaired loans, where an allowance is established based on the fair value of collateral, require classification in the fair value hierarchy. These impaired loans are classified as Level 3. Impaired loans measured using discounted future cash flows are not deemed to be measured at fair value.

Mortgage Loans to be Sold

Mortgage loans to be sold carried at the lower of cost or market value. The fair values of mortgage loans to be sold are based on current market rates from investors within the secondary market for loans with similar characteristics. Carrying value approximates fair value. These loans are classified as Level 2.

Certain assets and liabilities are measured at fair value on an ongoing basis; that is, the instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment). The following tables present information about certain assets and liabilities measured at fair value on a nonrecurring basis at December 31, 2020 and 2019.

The following table provides information describing the unobservable inputs used in Level 3 fair value measurements at December 31, 2020:

	Inputs
	Valuation Technique	Unobservable Input	General Range of Inputs
Impaired Loans	Appraisal Value/Comparison Sales/Other Estimates	Appraisals and/or Sales of Comparable Properties	Appraisals Discounted 10% to 20% for Sales Commissions and Other Holding Costs

Accounting standards require disclosure of fair value information for all of our assets and liabilities that are considered financial instruments, whether or not recognized on the balance sheet, for which it is practicable to estimate fair value.

Under the accounting standard, fair value estimates are based on existing financial instruments without attempting to estimate the value of anticipated future business and the value of the assets and liabilities that are not financial instruments. Accordingly, the aggregate fair value amounts of existing financial instruments do not represent the underlying value of those instruments on our books.

The following paragraphs describe the methods and assumptions we use in estimating the fair values of financial instruments:

a. Cash and due from banks, interest-bearing deposits at the Federal Reserve Bank

The carrying value approximates fair value. All mature within 90 days and do not present unanticipated credit concerns.

b. Investment securities available for sale 

Investment securities available-for-sale are recorded at fair value on a recurring basis. Fair value measurement is based upon quoted prices, if available. If quoted prices are not available, fair values are measured using independent pricing models or other model-based valuation techniques such as the present value of future cash flows, adjusted for the security’s credit rating, prepayment assumptions and other factors such as credit loss assumptions.

c. Loans 

The fair value of the Company’s loan portfolio includes a credit risk assumption in the determination of the fair value of its loans. This 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: variable rate loans, impaired loans and all other loans. The results are then adjusted to account for credit risk as described above. However, under the new guidance, the Company believes 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. Additionally, in accordance with ASU 2016-01, Recognition and Measurement of Financial Assets and Liabilities, 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. Fair values for impaired loans are estimated using discounted cash flow models or based on the fair value of the underlying collateral.

d. Deposits 

The estimated fair value of deposits with no stated maturity is equal to the carrying amount. The fair value of time deposits is estimated by discounting contractual cash flows, using interest rates currently being offered on the deposit products. The fair value estimates for deposits do not include the benefit that results from the low cost funding provided by the deposit liabilities as compared to the cost of alternative forms of funding (deposit base intangibles).

e. Accrued interest receivable and payable 

Since these financial instruments will typically be received or paid within three months, the carrying amounts of such instruments are deemed a reasonable estimate of fair value.

f. Loan commitments 

Estimates of the fair value of these off-balance sheet items are not made because of the short-term nature of these arrangements and the credit standing on the counterparties.

The following tables present the carrying amount, fair value, and placement in the fair value hierarchy of our financial instruments as of December 31, 2020 and 2019, respectively.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)

12 Months Ended

Dec. 31, 2020

Accounting Policies [Abstract]

Principles of Consolidation

Principles of Consolidation:  

The accompanying consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary, the Bank. In consolidation, all significant intercompany balances and transactions have been eliminated.

References to “we,” “us,” “our,” “the Bank,” or “the Company” refer to the parent and its subsidiary that are consolidated for financial purposes.

Accounting Estimates and Assumptions

Accounting Estimates and Assumptions:  

The financial statements are prepared in conformity with GAAP, which require management to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reported periods. Actual results could differ significantly from these estimates and assumptions. Material estimates generally susceptible to significant change are related to the determination of the allowance for loan losses, impaired loans, other real estate owned, deferred tax assets, the fair value of financial instruments and other-than-temporary impairment of investment securities.

Reclassification

Reclassification:  

Certain amounts in the prior years’ financial statements have been reclassified to conform to the current year’s presentation. Such reclassifications have no effect on shareholders’ equity or the net income as previously reported.

Subsequent Events

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 as of the date of the balance sheet, including the estimates inherent in the process of preparing financial statements. Non-recognized subsequent events are events that provide evidence about conditions that did not exist as of the date of the balance sheet but arose after that date. We have reviewed events occurring through the date the financial statements were available to be issued and no subsequent events occurred requiring accrual or disclosure.

Cash and Cash Equivalents

Cash and Cash Equivalents:  

Cash and cash equivalents include working cash funds, due from banks, interest-bearing deposits at the Federal Reserve, items in process of collection and federal funds sold. All cash equivalents are readily convertible to cash and have maturities of less than 90 days.

Depository institutions are required to maintain reserve and clearing balances at the Federal Reserve Bank. Vault cash satisfied our daily reserve requirement for the years ended December 31, 2020 and 2019, respectively. 

Interest-bearing Deposits at the Federal Reserve

Interest-bearing Deposits at the Federal Reserve:  

Interest-bearing deposits at the Federal Reserve mature daily and are carried at cost.

Investment Securities

Investment Securities:  

We classify investments into three categories: (1) Held to Maturity - debt securities that we have the positive intent and ability to hold to maturity, which are reported at amortized cost, adjusted for the amortization of any related premiums or the accretion of any related discounts into interest income using a methodology which approximates a level yield of interest over the estimated remaining period until maturity; (2) Trading - debt and equity securities that are bought and held principally for the purpose of selling them in the near term, which are reported at fair value, with unrealized gains and losses included in earnings; and (3) Available for Sale - debt and equity securities that may be sold under certain conditions, which are reported at fair value, with unrealized gains and losses excluded from earnings and reported as a separate component of shareholders’ equity, net of income taxes. Unrealized losses on securities due to fluctuations in fair value are recognized when it is determined that an other than temporary decline in value has occurred.

Realized gains or losses on the sale of investments are recognized on a specific identification, trade date basis. All securities were classified as available for sale for 2020 and 2019.

Mortgage Loans to be Sold

Mortgage Loans to be Sold:  

We originate fixed and variable rate residential mortgage loans on a service release basis in the secondary market. Loans closed but not yet settled with an investor are carried in our loans held for sale portfolio.   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 our customers.  Therefore, these loans present very little market risk.  We usually deliver to, and receive funding from, the investor within 30 to 60 days.  Commitments to sell these loans to the investor are considered derivative contracts and are sold to investors on a “best efforts” basis. We are not obligated to deliver a loan or pay a penalty if a loan is not delivered to the investor. Because of the short-term nature of these derivative contracts, the fair value of the mortgage loans held for sale in most cases is materially the same as the value of the loan amount at its origination.

Mortgage loans originated and intended for sale in the secondary market are carried at the lower of cost or estimated market value in the aggregate. Net unrealized losses are provided for in a valuation allowance by charges to operations as a component of mortgage banking income. Gains or losses on sales of loans are recognized when control over these assets are surrendered and are included in mortgage banking income in the consolidated statements of income.

Loans and Allowance for Loan Losses

Loans and Allowance for Loan Losses:   

Loans are carried at principal amounts outstanding. Loan origination fees, net of certain direct origination costs, are deferred and recognized over the weighted average life of the loan as an adjustment to yield. Interest income on all loans is recorded on an accrual basis. The accrual of interest and the amortization of net loan fees are generally discontinued on loans that 1) are maintained on a cash basis because of deterioration in the financial condition of the borrower; 2) the payment of full principal is not expected; or 3) the principal or interest has been in default for a period of 90 days or more. We define past due loans based on contractual payment and maturity dates.

The accrual of interest is generally discontinued on loans that become 90 days past due as to principal or interest. The accrual of interest on some loans may continue even though they are 90 days past due if the loans are well secured or in the process of collection and management deems it appropriate. If non-accrual loans decrease their past due status to less than 30 days for a period of six to nine months, they are reviewed individually by management to determine if they should be returned to accrual status.

When the ultimate collectability of an impaired loan’s principal is in doubt, wholly or partially, all cash receipts are applied 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. When this doubt does not exist, cash receipts are applied under the contractual terms of the loan agreement first to interest income and then to principal.  

We account for impaired loans by requiring that all loans (greater than $50,000) where it is estimated that we will be unable to collect all amounts due according to the terms of the loan agreement be recorded at the loan’s fair value. Fair value may be determined based upon the present value of expected future cash flows discounted at the loan’s effective interest rate, or the fair value of the collateral less cost to sell, if the loan is collateral dependent.

Additional accounting guidance allows us to use existing methods for recognizing interest income on an impaired loan. The guidance also requires additional disclosures about how we estimate interest income related to our impaired loans.

A loan is also considered impaired if its terms are modified in a troubled debt restructuring (“TDR”). For this type of impaired loan, cash receipts are typically applied to principal and interest receivable in accordance with the terms of the restructured loan agreement. Interest income is recognized on these loans using the accrual method of accounting, provided they are performing in accordance with their restructured terms.

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

We believe that the allowance is adequate to absorb inherent losses in the loan portfolio; however, there can be no assurance that loan losses in future periods will not exceed the current allowance amount or that future increases in the allowance will not be required. No assurance can be given that our ongoing evaluation of the loan portfolio, in light of changing economic conditions and other relevant circumstances, will not require significant future additions to the allowance, thus adversely affecting our operating results.

The allowance is also subject to examination by regulatory agencies, which may consider factors such as the methodology used to determine adequacy and the size of the allowance relative to that of peer institutions and other adequacy tests. In addition, such regulatory agencies could require us to adjust our allowance based on information available at the time of the examination.

The methodology used to determine the reserve for unfunded lending commitments, which is included in other liabilities, is inherently similar to the methodology used to determine the allowance adjusted for factors specific to binding commitments, including the probability of funding and historical loss ratio.

Concentration of Credit Risk

Concentration of Credit Risk:  

Our primary market consists of the counties of Berkeley, Charleston and Dorchester, South Carolina. As of December 31, 2020, the majority of the total loan portfolio, as well as a substantial portion of the commercial and real estate loan portfolios, were to borrowers within this region. No other areas of significant concentration of credit risk have been identified.

Premises, Equipment and Leasehold Improvements and Depreciation

Premises, Equipment and Leasehold Improvements and Depreciation:  

Land is carried at cost. Buildings and equipment are stated at cost less accumulated depreciation. Depreciation is recorded using the straight-line method for financial reporting purposes and accelerated methods for income tax purposes over the estimated useful lives of the assets ranging from 40 years for buildings and 3 to 15 years for equipment. Leasehold improvements are amortized over the shorter of the asset’s useful life or the remaining lease term, including renewal periods when reasonably assured. The cost of maintenance and repairs is charged to operating expense as incurred.

Leases

Leases:

In accordance with ASU 2016-02, the Company determines if a contractual arrangement is a lease at inception. Operating leases are included in the operating right of use (“ROU”) assets and current operating lease liabilities on the Company’s Consolidated Balance Sheet. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Currently, the Company does not have any finance leases.

Beginning January 1, 2019, operating lease ROU assets and lease liabilities are recognized at the commencement of the lease based on the present value of lease payments over the lease term. The lease payments included in the present value are fixed payments and index-based variable lease payments. The Company estimates the incremental borrowing rate, based on information available at the commencement of the lease, as most of the Company’s leases do not include an implicit rate.

Income Taxes

Income Taxes:  

We account for income taxes under the asset and liability method. Deferred tax assets and liabilities are recognized for future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using the enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Net deferred tax assets are included in other assets in the consolidated balance sheet.

Accounting standards require the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements. These standards also prescribe a recognition threshold and measurement of a tax position taken or expected to be taken in an enterprise’s tax return. We believe that we had no uncertain tax positions for the years ended December 31, 2020 and 2019.

Stock-Based Compensation

Stock-Based Compensation:  

Compensation cost is recognized for stock options issued to employees, based on the fair value of these awards at the date of grant. A Black-Scholes model is utilized to estimate the fair value of stock options. Compensation cost is recognized over the required expected term, generally defined as the average vesting period (7.5 years).

Income Per Common Share

Income Per Common Share:  

Basic income per share is computed by dividing net income by the weighted-average number of common shares outstanding. Diluted earnings per share is computed by dividing net income by the weighted-average number of common shares and potential common shares outstanding. Potential common shares consist of dilutive stock options determined using the treasury stock method and the average market price of common stock. Earnings per share are restated for all stock splits and stock dividends through the date of issuance of the financial statements.

Segment Information

Segment Information:  

The Company operates and manages itself within one retail banking segment and therefore has not provided segment disclosures.

Interest Rate Lock Commitments and Forward Sale Contracts

Interest Rate Lock Commitments and Forward Sale Contracts:  

Commitments to fund mortgage loans (interest rate locks) to be sold into the secondary market and forward commitments for the future delivery of these mortgage loans are accounted for as free-standing derivatives. The fair value of the interest rate lock is recorded at the time the commitment to fund the mortgage loan is executed and is adjusted for the expected exercise of the commitments before the loan is funded. In order to hedge the change in interest rates resulting from commitments to fund the loans, we enter into forward commitments for the future delivery of mortgage loans when the interest rate is locked. Fair values of these mortgage derivatives are estimated based on changes in mortgage interest rates from the date the interest on the loan is locked. Changes in the fair values of these derivatives are included in income when they occur. As a result of the short-term nature of mortgage loans held for sale (derivative contract), our derivative instruments were considered to be immaterial as of December 31, 2020 and 2019.

We had no embedded derivative instruments requiring hedge accounting treatment at December 31, 2020. We do not currently engage in hedging activities.

Recent Accounting Pronouncements

Recent Accounting Pronouncements:  

The following is a summary of recent authoritative pronouncements that could impact the accounting, reporting and/or disclosure of financial information by the Company.

In June 2016, the FASB issued ASU 2016-13, Financial instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, to change the accounting for credit losses and modify the impairment model for certain debt securities. In May 2019, the FASB issued guidance to provide entities with an option to irrevocably elect the fair value option, applied on an instrument-by-instrument basis for eligible instruments, upon adoption of ASU 2016-13, Measurement of Credit Losses on Financial Instruments. In October 2019, the FASB voted to extend the implementation date for smaller reporting companies, non-SEC public companies, and private companies. On March 27, 2020, the Board of Governors of the Federal Reserve, FDIC, and Office of the Comptroller of Currency announced the interim final rule allowing banks to delay the effects of CECL until 2022 for filers scheduled to implement in 2020 and 2023 for all other filers. This amendment will become effective for the Company on January 1, 2023. The Company is currently evaluating the effect that implementation of the new standard will have on its financial position, results of operations, and cash flows. It will be influenced by the quality, composition, and characteristics of our loan and investment portfolios, as well as the expected economic conditions and forecasts at the time of enactment and future reporting periods.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement.

Early adoption will continue to be permitted. For entities that have not yet adopted the guidance in ASU 2016-13, the effective dates and the transition requirements for these amendments are the same as the effective date and transition requirements in ASU 2016-13. The Company does not expect these amendments to have a material effect on its financial statements.

In March 2020, the FASB issued guidance to provide temporary optional guidance to ease the potential burden in accounting for reference rate reform. The amendments are effective as of March 12, 2020 through December 31, 2022. The Company does not expect these amendments to have a material effect on its financial statements.

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