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 four banking house locations: 256 Meeting Street, Charleston, SC; 100 North Main Street, Summerville, SC; 1337 Chuck Dawley Boulevard, Mt. Pleasant, SC; and 2027 Sam Rittenberg Boulevard, Charleston, SC. We intend to open a banking office in North Charleston, SC on Highway 78 and Ingleside Boulevard in the future (copy of the lease incorporated as Exhibit 10.13 in the June 30, 2017 Form 10-Q).

The Charleston – North Charleston metro area grew 15.2% between 2011 and 2016 according to the U.S. Bureau of Economic Analysis. The primary economic drivers of our market area are manufacturing, tourism, technology, and the healthcare industry. This includes manufacturing campuses for Boeing, Volvo Cars, and Mercedes-Benz Vans’ in the area. Tourism has also contributed to the economic growth as both Conde Nast Traveler and Travel Leisure Magazine have recognized the area as a top tourism destination. Additionally, Charleston is considered the number one mid-sized U.S. metro area for IT growth according to the U.S. Bureau of Labor Statistics.

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 possessing 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, 2017, $51.7 million, or 19.14%, 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 term 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 we 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 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.

Commercial Real Estate Loans

As of December 31, 2017, commercial real estate construction loans comprised $2.3 million, or 0.86%, of our loan portfolio. We make construction loans for commercial properties to businesses. Advances on construction loans are 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 12 months and are often 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 estimate of the 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, 2017, $140.2 million, or 51.89%, 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.

5

Commercial real estate loans generally carry higher credit risks, as they typically involve larger loan balances concentrated with single borrowers or groups 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 dependent, in large part, on 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 $70.8 million, or 26.20%, of the loan portfolio as of December 31, 2017. Consumer real estate loans consist of consumer construction loans, consumer real estate loans, HELOCs, and mortgage originations. We make 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. 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 estimate of the 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.

Consumer real estate loans consist 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.

In addition to consumer real estate loans, 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 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.

All residential loans that we originate are underwritten pursuant to our policies and procedures. We originate both adjustable-rate and fixed-rate loans. A rising interest rate environment that typically results in decreased loan demand may adversely affect our loan origination and sales activity.

Other consumer loans totaled $5.2 million and were 1.91% of the loan portfolio as of December 31, 2017. These loans are originated for various purposes, including the purchase of automobiles, boats, and other legitimate personal purposes.

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.

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 information on the historical and projected income and expenses of the borrower.

6

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, 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, 2017, we employed 77 people, with three individuals considered part time and one individual 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, 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, in 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, and 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.

7

The Dodd-Frank Act created the Consumer Financial Protection Bureau (the “CFPB”) as an agency 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. At December 31, 2017, 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. Moreover, as a bank holding company located in South Carolina, the Company is also subject to the regulations of the South Carolina State Board of Financial Institutions.

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. 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. 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 guideline, 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.

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.

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

8

● 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 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, governing disclosures of credit terms to consumer borrowers

● The Home Mortgage Disclosure Act of 1975, requiring 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, fair equitable, and nondiscriminatory access to credit for consumers

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

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

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

● 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

● The Electronic Funds Transfer Act and the Federal Reserve Board issued Regulation E to implement the act, which governs automatic deposits to and withdrawals from deposit 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. Regulation DD requires depository institutions to provide disclosures so that consumers can make meaningful comparisons among depository institutions.

9

Enforcement Powers

The Company is subject to supervision and examination by 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. 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.

On January 28, 2014, we signed a lease to open a banking office on Highway 78 and Ingleside Boulevard, North Charleston, SC in the future (copy of the lease incorporated as Exhibit 10.8 in the 2013 10-K and copy of the Assignment and Assumption of Lease incorporated as Exhibit 10.9, First Amendment to the Lease incorporated as Exhibit 10.10 and Second Amendment to the Lease incorporated as Exhibit 10.11 in the 2015 10-K). On July 31, 2017, a new lease agreement was authorized and is incorporated as Exhibit 10.13 filed with the June 30, 2017 Form 10-Q. The Company owns the 2027 Sam Rittenberg Boulevard location, which houses the Operations Department of the Bank as well as operating as a banking office. The Company leases all other locations. The owned location is not encumbered and all of the leases have renewal options. Each banking location is suitable and adequate for banking operations.

Item 3. Legal Proceedings

In our opinion, there are no other legal proceedings pending other than routine litigation incidental to the Company’s business involving amounts that are not material to our financial condition.

The future payment of cash dividends is subject to the discretion of the Board of Directors and depends upon 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 amount of dividends 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. As of the date of this report, the Company owns 241,396 shares, adjusted for three 10% stock dividends, a 10% stock distribution, and a 25% stock dividend. At the Annual Meeting in April 2007, the shareholders’ voted to increase the number of authorized shares from 6,000,000 to 12,000,000. As of February 15, 2018, there were 5,232,275 shares of common stock issued and 4,990,879 shares of common stock outstanding.

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 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).

12

The Board of Directors of the Bank approved a cash contribution of $375,000 to The Bank of South Carolina ESOP for the fiscal year ended December 31, 2017. The Board of Directors of the Bank approved cash contributions of $345,000 and $315,000 for the fiscal years ended December 31, 2016 and 2015, 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, 2017, the Plan owned 286,013 shares of common stock of the Company.

THE BANK OF SOUTH CAROLINA STOCK INCENTIVE PLAN

We have a Stock Incentive Plan, which was approved in 1998, with 180,000 (329,422 adjusted for three 10% stock dividends, a 10% stock distribution, and a 25% stock dividend) shares reserved, and a Stock Incentive Plan, which was approved in 2010, with 300,000 (330,000 adjusted for a 10% stock dividend) 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, 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.

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 $446,566,498 in assets as of December 31, 2017 and net income of $848,699 and $4,901,825, respectively, for the three and twelve months ended December 31, 2017. 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 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. The allowance is increased or decreased through the provisioning process. 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 as of December 31, 2017 as compared to December 31, 2016 and our operating results for 2017 compared to 2016 and 2016 compared to 2015, 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.

15

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”.

COMPARISON OF THE YEAR ENDED DECEMBER 31, 2017 TO DECEMBER 31, 2016

Net income decreased $345,238 or 6.58% to $4,901,825, or basic and diluted income per share of $0.99 and $0.97, respectively for the year ended December 31, 2017 from $5,247,063 or basic and diluted income per share of $1.06 and $1.04, respectively for the year ended December 31, 2016. The decrease in net income was primarily due to the enactment of the Tax Cuts and Jobs Act on December 22, 2017 and the related revaluation of the deferred tax asset. Deferred tax assets and liabilities must be adjusted to legislation based on the enactment date not the effective date; therefore, the deferred tax asset was revalued at a corporate tax rate of 21% instead of 34% in accordance with GAAP at December 22, 2017. This revaluation resulted in additional income tax expense of $666,674. Our returns on average assets and average equity for the year ended December 31, 2017 were 1.14% and 11.37%, respectively, compared with 1.28% and 12.65%, respectively, for the year ended December 31, 2016.

Net interest income increased $828,427 or 5.55% to $15,745,284 for the year ended December 31, 2017 from $14,916,857 for the year ended December 31, 2016. This increase was primarily due to increases in interest and fees on loans and investment securities. Interest and fees on loans increased $435,418 or 3.89% to $13,287,318 for the year ended December 31, 2017 from $12,851,900 for the year ended December 31, 2016, as the result of the increases in the Federal Funds rate set by the Federal Reserve. Interest income on investment securities increased $306,944 or 13.32% to $2,612,018 for the year ended December 31, 2017 from $2,305,074 for the year ended December 31, 2016 a result of the increase in the average balance of investment securities from $110,762,289 for the year ended December 31, 2016 to $130,161,937 for the year ended December 31, 2017.

Average earning assets increased $16,214,247 or 4.03% to $418,602,052 for the year ended December 31, 2017 from $402,387,805 for the year ended December 31, 2016. This is primarily related to the increase in the average balance of investment securities as stated in the previous paragraph.

The provision to the allowance for loan losses for the year ended December 31, 2017 was $55,000 compared to $570,000 for the year ended December 31, 2016. The decrease was primarily a result of slower loan growth in the first three quarters of the year and lower net charge-offs. The Board of Directors determined that this provision was appropriate based upon the strength of our reserve and the anticipation of continued loan growth and an improving economy. Charge-offs of $185,449 and recoveries of $154,230, together with the provision to the allowance, resulted in an allowance for loan losses of $3,875,398 or 1.43% of total loans at December 31, 2017.

Other income decreased $592,612 or 20.71% to $2,268,471 for the year ended December 31, 2017. Our mortgage banking income decreased $330,283 or 23.80% to $1,057,457 for the year ended December 31, 2017 from $1,387,740 for the year ended December 31, 2016 due to decreased volume. We were also impacted by an increase in competition as new banks enter the market area. Mortgage banking income is highly influenced by mortgage interest rates and the housing market. Mortgage loan originations decreased $20,241,046 or 26.62% to $55,791,625 for the year ended December 31, 2017 from $76,032,671 for the year ended December 31, 2016. We also had gains of $380,904 on the sales of investment securities during the year ended December 31, 2016 compared to gains of $45,820 during the year ended December 31, 2017, a decrease of $335,084 or 87.97%. The decrease in gains was due to the little difference between short-term and long-term rates for bonds of the same credit quality in the current market.

Other expense decreased $30,148 or 0.29% to $10,242,296 for the year ended December 31, 2017, from $10,272,444 for the year ended December 31, 2016. Salaries and employee benefits decreased $27,098 or 0.45% from $6,087,929 for the year ended December 31, 2016 to $6,060,831 for the year ended December 31, 2017. Other operating expenses decreased $122,039 to $2,517,737 during the year ended December 31, 2017 from $2,639,776 during the year ended December 31, 2016. This decrease was primarily attributable to a decrease in state and FDIC insurance and fees. Our net occupancy expense increased $43,028 or 2.82% to $1,571,076 for the year ended December 31, 2017, from $1,528,048 for the year ended December 31, 2016. Our net occupancy expense includes rent and insurance on our banking locations as well as the cost of repairs and maintenance on these facilities. Occupancy expense increased primarily due to annual rent increases at our Meeting Street and Summerville banking locations as well as an increase in insurance on banking locations, offset by a decrease in the cost of maintenance and repairs and depreciation on furniture, fixtures and equipment.

16

For the year ended December 31, 2017, the Company’s effective tax rate was 36.48% compared to 24.34% during the year ended December 31, 2016. The increase in the effective tax rate is directly related to the income tax expense recorded due to the revaluation of the deferred tax asset. As a result of the enactment of the Tax Cuts and Jobs Act changing the corporate tax rate to 21% from 34%, the deferred tax asset was revalued on December 22, 2017. This revaluation resulted in additional income tax expense of $666,674.

COMPARISON OF THE YEAR ENDED DECEMBER 31, 2016 TO DECEMBER 31, 2015

Net income increased $362,775 or 7.43% to $5,247,063, or basic and diluted income per share of $1.06 and $1.04, respectively for the year ended December 31, 2016 from $4,884,288 or basic and diluted income per share of $0.99 and $0.96, respectively for the year ended December 31, 2015. This increase is primarily due to increases in interest and fees on loans offset by higher provision for loan losses expense and lower mortgage banking income. Our returns on average assets and average equity for the year ended December 31, 2016 were 1.28% and 12.65%, respectively, compared with 1.29% and 12.64%, respectively, for the year ended December 31, 2015.

Net interest income increased $1,089,304 or 7.88% to $14,916,857 for the year ended December 31, 2016 from $13,827,553 for the year ended December 31, 2015. This increase was primarily due to increases in interest and fees on loans and other interest income. Interest and fees on loans increased $1,056,597 or 8.96% to $12,851,900 for the year ended December 31, 2016 from $11,795,303 for the year ended December 31, 2015, as the result of higher average loan balances, an improving local economy, and consumer confidence. Other interest income, earned mostly on interest-bearing deposits in other banks, increased $93,057 or 204.22% to $138,623 for the year ended December 31, 2016 from $45,566 for the year ended December 31, 2015.

Average earning assets increased $30,474,873 or 8.19% to $402,387,805 for the year ended December 31, 2016 from $371,912,932 for the year ended December 31, 2015. Average loans increased $21,421,628 or 8.79% for the year ended December 31, 2016. Average interest-bearing deposits in other banks increased $8,924,355 or 50.85% to $26,474,258 for the year ended December 31, 2016 from $17,549,903 for the year ended December 31, 2015.

The provision to the allowance for loan losses for the year ended December 31, 2016 was $570,000 compared to $192,500 for the year ended December 31, 2015. The increase was primarily a result of loan growth. The Board of Directors determined that this provision was appropriate based upon the strength of our reserve and the anticipation of continued loan growth and an improving economy. Charge-offs of $208,295, recoveries of $72,085, together with the provision to the allowance, resulted in an allowance for loan losses of $3,851,617 or 1.48% of total loans at December 31, 2016.

Non-interest income decreased $188,875 or 6.19% to $2,861,083 for the year ended December 31, 2016. Our mortgage banking income decreased $217,936 or 13.57% to $1,387,740 for the year ended December 31, 2016 from $1,605,676 for the year ended December 31, 2015 due to the loss of two loan originators during 2016. Mortgage banking income is highly influenced by mortgage interest rates and the housing market. According to local real estate market reports, the sales volume in the Charleston market increased 10% for the year ended December 31, 2016 compared to the year ended December 31, 2015. The Charleston market had 17,114 home sales during 2016 with a median sales price of $245,000 compared to 16,202 home sales in 2015 at a median price of $229,000. Mortgage loan originations decreased $15,021,252 or 16.50% to $76,032,671 for the year ended December 31, 2016 from $91,053,923 for the year ended December 31, 2015. Service charges, fees and commissions increased $70,342 to $1,061,349 for the year ended December 31, 2016 from $991,007 for the year ended December 31, 2015. This increase was primarily due to an increase of $52,416 in debit card fees resulting from increased usage particularly by our business customers. We also had gains of $380,904 on the sales of investment securities during the year ended December 31, 2016 compared to gains of $423,832 during the year ended December 31, 2015.

Other expense increased $758,969 or 7.98% to $10,272,444 for the year ended December 31, 2016, from $9,513,475 for the year ended December 31, 2015. Salaries and employee benefits increased $228,726 or 3.90% from $5,859,203 for the year ended December 31, 2015 to $6,087,929 for the year ended December 31, 2016. Base wages increased $134,013 to $4,768,176 for the year ended December 31, 2016. This increase was primarily due to annual merit increases. Our contribution to the ESOP increased from $315,000 in 2015 to $345,000 for 2016.

17

Other operating expenses increased $471,394. During 2016, the Company invested in a South Carolina Historic Rehabilitation Tax Credit of $937,211, which will be amortized over three years. As of December 31, 2016, the balance of the credit was $612,211. For the year ended December 31, 2016, the Company amortized $325,000 of the credit.

Our net occupancy expense increased $47,442 or 3.20% to $1,528,048 for the year ended December 31, 2016, from $1,480,606 for the year ended December 31, 2015. Our net occupancy expense includes rent and insurance on our banking locations as well as the cost of repairs and maintenance on these facilities. Occupancy expense increased primarily due to annual rent increases at our Meeting Street and Summerville banking locations as well as an increase in insurance on banking locations, offset by a decrease in the cost of maintenance and repairs and depreciation on furniture, fixtures and equipment.

For the year ended December 31, 2016, the Company’s effective tax rate was 24.34% compared to 31.89% during the year ended December 31, 2015. The Company invested in a South Carolina Historic Rehabilitation Tax Credit during 2016, which resulted in a decrease to the effective rate.

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, 2017, total assets increased 7.88% to $446,566,498 and total deposits increased 8.15% to $402,888,300 from December 31 2016.

As of December 31, 2017, earning assets, which are composed of U.S. Treasury, Government Sponsored Enterprises and Municipal Securities in the amount of $139,250,250, interest-bearing deposits at the Federal Reserve in the amount of $24,034,194 and total loans, including mortgage loans held for sale, in the amount of $272,274,363, consisted of approximately 97.54% 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 deposit liabilities are issued with fixed terms and can be repriced only at maturity.

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 six-month period. By adhering to this policy, we anticipate that our net interest margins will not be materially affected, unless there is an extraordinary precipitous change in interest rates. The average net interest rate spread for 2017 increased to 3.70% from 3.64% for 2016 and the average net interest margin for 2017 increased to 3.76% from 3.71% for 2016. At December 31, 2017 and 2016, 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.

18

At December 31, 2017, the average maturity of the investment portfolio was 3.90 years with an average yield of 2.04% compared to 4.13 years with an average yield of 1.99% at December 31, 2016.

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, 2017.

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, 2017.

	Payment Due by Period

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 38.93% and 36.38% of total assets at December 31, 2017 and 2016, 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, 2017, 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, 2017, we could borrow up to $88.2 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, 2017 and 2016, our liquidity ratio was 37.68% and 38.27%, respectively.

Average earning assets increased by $16,214,247 from 2016 to 2017. This increase was primarily due to a $19,399,648 increase in investment securities available for sale. Throughout the year, the Bank bought investment securities when liquidity was greater than needed and loan demand was stable to improve the yield earned on our investment securities portfolio.

At December 31, 2017, we had eight U.S. Treasury Notes with an unrealized loss of $411,145 compared to four U.S. Treasury Notes with an unrealized loss of $250,385 at December 31, 2016. At December 31, 2017, we had 15 Government-Sponsored Enterprises with an unrealized loss of $887,811 compared to eight Government-Sponsored Enterprises with an unrealized loss of $833,321 at December 31, 2016. At December 31, 2017, we had 49 Municipal Securities with an unrealized loss of $545,146 compared to 54 Municipal Securities with an unrealized loss of $816,413 at December 31, 2016. Interest rate increases caused the unrealized losses on these investments. 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, to manage fluctuations in deposits and liquidity, to satisfy pledging requirements and to 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 review 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, 2017, outstanding loans (including mortgage loans and deferred loan fees of $152,047) totaled $270,180,640, which equaled 67.06% of total deposits and 60.50% of total assets.

We had no foreign loans or loans to fund leveraged buyouts at any time during the years ended December 31, 2013 through December 31, 2017.

The following table presents the contractual terms to maturity for loans outstanding at December 31, 2017. 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 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.

24

Impairment loss is measured by:

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

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.

	Impaired and Non-Accrual Loans as of December 31,
Loan	2017		2016		2015		2014		2013
Non-Accrual Loans	$	831,859	$	1,741,621	$	2,061,088	$	882,413	$	1,575,440

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.

	Troubled Debt Restructurings as of December 31,
	2017		2016		2015		2014		2013
Number of TDRs		1		2		3		2		4
Amount of TDRs	$	33,300	$	378,382	$	458,268	$	466,541	$	1,196,341

Financial Accounting Standards Board Accounting 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 $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. During the year ended December 31, 2014 a loan receivable with a balance of $496,090, was removed from TDR status. The borrower consistently paid as agreed and made substantial reductions to principal. In addition, one loan receivable was paid off during the year ended December 31, 2014 with a balance of $106,194 at December 31, 2013. We do not know of any potential problem loans which will not meet their contractual obligations that are not otherwise discussed herein.

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, the Company’s Risk Management Officer 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 Financial Accounting Standards Board (“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.

25

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. Historical losses are segregated into risk-similar groups and a loss ratio is determined for each group over a five-year period. The five-year average loss ratio by 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 “estimated loss” within our total 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 on 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%.

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 represent 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.

26

Although significantly under the threshold of 100% of capital (currently approximately $42.8 million), the number of overmargined real estate loans currently totals approximately $9,495,471 or approximately 3.51% of our loan portfolio at December 31, 2017 compared to $10,015,945 or approximately 3.84% of the loan portfolio at December 31, 2016.

A credit rating matrix is used to rate all extensions of credit and to provide a more specified 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. One hundred percent of our loans are 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, political uncertainty, international instability, as well as problems in the traditional mortgage market are a few of the trends and conditions that are currently affecting the national and local economies. 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 any extension of credit, every significant commercial loan goes through sound credit underwriting. The Credit Department conducts a detailed cash flow on each proposal using the most current financial information.

Experience, ability and depth of lending management staff  

We have over 350 combined years of lending experience among our lending staff. In addition to the lending staff, we have an Advisory Board for each office, including the anticipated North Charleston branch, comprised of business and community leaders from the specific office market area. We meet with these advisory boards quarterly to discuss the trends and conditions in each respective market. 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 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 concentration, geographic concentration and regulatory concentration. As of December 31, 2017, three Standard Industrial Code groups comprised more than 2% of our total outstanding loans. The groups are activities related to real estate, offices and clinics of doctors, and offices of lawyers. 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.

27

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.

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 improving.

Based on our allowance for loan loss model, we recorded a provision for loan loss of $55,000 for the year ended December 31, 2017 primarily based on our analysis of the adequacy of the allowance for loan losses, compared to $570,000 for the year ended December 31, 2016. At December 31, 2016, the five-year average loss ratios were: 0.110% Commercial, 0.00% Commercial Real Estate Construction, .073% Commercial Real Estate Other, 0.064% Consumer Real Estate, and .064% Consumer Other.

During the year ended December 31, 2017, charge-offs of $185,449 and recoveries of $154,230 were recorded to the allowance for loan losses, resulting in an allowance for loan losses of $3,875,398 or 1.43% of total loans, compared to charge-offs of $208,295 and recoveries of $72,085 resulting in an allowance for loan losses of $3,851,617 or 1.48% of total loans at December 31, 2016.

Net charge-offs for the year ended December 31, 2017, were $31,219 as compared to net charge-offs of $136,210 for the year ended December 31, 2016. 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 6 to 9 months, they are reviewed individually to determine if they should be returned to accrual status. At December 31, 2017 there was one loan over 90 days past due still accruing interest compared to two loans over 90 days past due still accruing interest at December 31, 2016.  The loans at December 31, 2017 and 2016 were all considered impaired.

We believe the allowance for loan losses at December 31, 2017, 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.

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. No provision was recorded during the year ended December 31, 2017. A provision of $4,001 was recorded during the year ended December 31, 2016. The balance for the reserve for unfunded lending commitments was $24,826 as of December 31, 2017 and 2016.

OTHER REAL ESTATE OWNED

Real estate acquired because of foreclosure or by deed-in-lieu of foreclosure is classified as other real estate owned (“OREO”) until it is sold. When the property is acquired, it is recorded at the lesser of the fair value of the property less estimated selling costs or the total loan balance. It is in our best interest to determine the fair market value by engaging an independent appraisal within 30 days of property being acquired into OREO. We cannot hold the property for a period of more than five years unless we have prior approval from the Commissioner of Banking of the State Board of Financial Institutions. The Bank will pay property taxes along with insurance expenses until the property is sold. OREO at December 31, 2017 consisted of one property in the amount of $435,479 compared to one property in the amount of $521,943 at December 31, 2016. One loan receivable valued at $98,832 transferred to OREO and subsequently sold during the year ended December 31, 2017 for a loss of $1,477. One property sold during the year ended December 31, 2016 for a loss of $13,450. One loan receivable valued at $35,473 moved to OREO during the year ended December 31, 2014, and ultimately sold at a gain of $2,382. We had no OREO during the year ended December 31, 2013.

NONPERFORMING ASSETS

Nonperforming assets include OREO, nonaccrual loans and loans past due 90 days or more and still accruing interest. The following table summarizes nonperforming assets for the five years ended December 31, 2017:

Deposits increased $30,365,449 or 8.15% to $402,888,300 as of December 31, 2017, from $372,522,851 as of December 31, 2016. Non-interest bearing deposits increased $13,222,270 to $139,256,748 as of December 31, 2017, primarily from new account growth and an improved economy. We also experienced larger balances in existing customer accounts including growth in our interest- bearing transaction accounts because of large real estate escrow funds.

We fund growth through core deposits. We do not have, nor do we rely on, Brokered Deposits or Internet Deposits as a source to do so.

SHORT-TERM BORROWINGS

Securities sold under agreements to repurchase with customers mature on demand. At December 31, 2017 and 2016, there were no securities sold under agreements to repurchase. There was no amount outstanding at any month-end during 2017.

At December 31, 2017 and 2016, 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 $88.2 million. We established this arrangement as an additional source of liquidity. There have been no borrowings under this arrangement.

At December 31, 2017 and 2016, the Bank had unused short-term lines of credit totaling approximately $23.0 million and $21.0 million, respectively (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.

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, 2017 and 2016, the balance of this reserve was $24,826. At December 31, 2017 and 2016, 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 $92,869,285 and $81,234,269 as of December 31, 2017 and 2016, 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, 2017 and 2016 was $1,219,644 and $793,992, 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 $2,093,723 at December 31, 2017, to sell loans held for sale of $2,093,723, compared to forward sales commitments of $4,386,210 at December 31, 2016, to sell loans held for sale of $4,386,210. The fair value of these commitments was not significant at December 31, 2017 or 2016. 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 $13.4 million at December 31, 2017 and $18.1 million at December 31, 2016. For the twelve months ended December 31, 2017 and December 31, 2016, 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 $10,600,000 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, 2017 was $42,764,635. 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.

32

At December 31, 2017, the Bank was categorized as “well capitalized”. To be categorized as “well capitalized” the Bank must maintain minimum total risk based, Tier 1 risk based, common equity Tier 1 risk based capital and Tier 1 leverage ratios of 10.00%, 8.00%, 6.50% and 5.00%, respectively, and to be categorized as “adequately capitalized,” the Bank must maintain minimum total risk based, Tier 1 risk based, common equity Tier 1 risk based capital, and Tier 1 leverage ratios of 8.00%, 6.00%, 4.50%, and 4.00%, respectively.

We are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory, and possibly additional discretionary, actions by regulators that, if undertaken, could have a material effect on the financial statements. We must meet specific capital guidelines that involve quantitative measures of our assets, liabilities and certain off-balance sheet items as calculated under regulatory accounting practices. Our capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors. Current and previous quantitative measures established by regulation to ensure capital adequacy require that we maintain minimum amounts and ratios of total and Tier 1 capital to risk-weighted assets and to average assets. We believe, as of December 31, 2017, 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, 2017.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and the Board of Directors 

Bank of South Carolina Corporation and Subsidiary 

Charleston, South Carolina

Opinion on the Financial Statements 

We have audited the accompanying consolidated balance sheets of Bank of South Carolina Corporation and its subsidiaries (the “Company”) as of December 31, 2017 and 2016, 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, 2017, 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, 2017 and 2016, and the results of its operations and its cash flows for the years then ended, 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.

We have served as the Company’s auditor since 2006.

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 preparation of the financial statements are 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, 2017 and 2016, respectively.

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 2017 and 2016.

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.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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 uncollectibility 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 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 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, 2017, 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.

Other Real Estate Owned: 

Fair value is based upon independent market prices, appraised values of the collateral, or our estimation of the value of the collateral. Losses arising from an initial foreclosure are charged against the allowance for loan losses. Subsequent to foreclosure, other real estate owned (“OREO”) is recorded at the lower of cost or fair value, adjusted for net selling costs. Gains and losses on the sale of OREO and subsequent write-downs from periodic re-evaluation are charged to net other real estate owned expenses.

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, 2017 and 2016.

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 service period, generally defined as the vesting period (10 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 has, therefore, 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, 2017 and 2016.

We had no embedded derivative instruments requiring hedge accounting treatment at December 31, 2017. 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 May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers, Topic 606. The core principle of the new standard is that an entity should recognize revenue to reflect the transfer of goods and services to customers in an amount equal to the consideration the entity receives or expects to receive. This guidance also includes expanded disclosure requirements that result in an entity providing users of financial statements with comprehensive information about the nature, amount, timing, and uncertainty of revenue and cash flows arising from the entity’s contracts with customers. In August 2015, the FASB deferred the effective date of the amendments. As a result of the deferral, the guidance will be effective for the Company for reporting periods beginning after December 15, 2017. We will apply this guidance using a modified retrospective approach. Because the amendment does not apply to revenue associated with financial instruments, such as loans and investment securities available for sale, we do not expect this amendment to have a material effect on our consolidated financial statements. We are still evaluating the effects of the amendment regarding its applicability and related impact on credit card fees and deposit service charges.

In January 2016, the FASB issued ASU 2016-01, Financial Instruments – Overall (Subtopic 825-10); Recognition and Measurement of Financial Instruments and Financial Liabilities. This update addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. The amendments will be effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. We will apply the guidance by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. The amendments related to equity securities without readily determinable fair values will be applied prospectively to equity investments that exist as of the date of adoption of the amendments. The Company does not expect this amendment to have a material effect on its financial statements.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which revises certain aspects of recognition, measurement, presentation, and disclosure of leasing transactions. The amendments will be effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. We are currently evaluating the effect that implementation of the new standard will have on our results of operations and cash flows but expect the effect on the financial position to be considerable due to the fact that substantially all operating lease commitments will be recognized as right of use assets and lease liabilities based on the present value of unpaid lease payments as of the date of adoption.

In March 2016, the FASB issued ASU 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net), to clarify the implementation guidance on principal versus agent considerations and address how an entity should assess whether it is the principal or the agent in contracts that include three or more parties. The amendments will be effective for the Company for reporting periods beginning after December 15, 2017. The Company does not expect this amendment to have a material effect on its financial statements.

In March 2016, the FASB issued ASU 2016-09, Compensation – Stock Compensation (Topic 718): Improvements to Employee Share – Based Payment Accounting, to simplify several aspects of the accounting for share-based payment award transactions including the income tax consequences, the classification of awards as either equity or liabilities, and the classification on the statement of cash flows. Additionally, the guidance simplifies two areas specific to entities other than public business entities allowing them apply a practical expedient to estimate the expected term for all awards with performance or service conditions that have certain characteristics and also allowing them to make a one-time election to switch from measuring all liability-classified awards at fair value to measuring them at intrinsic value. The amendments became effective for the Company on January 1, 2017 and this amendment did not have a material effect on its financial statements.

In April 2016, the FASB issued ASU 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing, to clarify guidance related to identifying performance obligations and accounting for licenses of intellectual property. The amendments will be effective for the Company for reporting periods beginning after December 15, 2017. The Company does not expect these amendments to have a material effect on its financial statements.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

In May 2016, the FASB issued ASU 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow- Scope Improvements and Practical Expedients, to clarify guidance related to collectability, noncash consideration, presentation of sales tax, and transition. The amendments will be effective for the Company for reporting periods beginning after December 15, 2017. The Company does not expect these amendments to have a material effect on its financial statements.

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. The amendments will be effective for the Company for reporting periods beginning after December 15, 2019. Early adoption is permitted for all organizations for periods beginning after December 15, 2018. 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.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, to clarify how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The amendments will be effective for the Company for fiscal years beginning after December 15, 2017 including interim periods within those fiscal years. Early adoption is permitted. The Company does not expect these amendments to have a material effect on its financial statements.

In December 2016, the FASB issued ASU 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers. These corrections make a limited number of revisions to several pieces of the revenue recognition standard issued in 2014. The effective date and transition requirements for the technical corrections will be effective for the Company for reporting periods beginning after December 15, 2017. The Company will continue to evaluate the impact of this ASU and does not expect these amendments to have a material effect on its financial statements.

In January 2017, the FASB issued ASU 2017-01, Clarifying the Definition of a Business, which provided guidance to assist with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The update is intended to address concerns that the existing definition of a business has been applied too broadly and has resulted in many transactions being recorded as business acquisitions that in substance are more akin to asset acquisitions. The amendments are effective for annual periods beginning after December 15, 2017, including interim periods within those periods. The amendments should be applied prospectively on or after the effective date. The Company does not expect this amendment to have a material effect on its financial statements.

In February 2017, the FASB issued ASU 2017-05, Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets, to clarify the scope of established guidance on nonfinancial asset derecognition, issued as part of ASU 2014-09, Revenue from Contracts with Customers, as well as accounting for partial sales of nonfinancial assets. The amendments conform the derecognition guidance on nonfinancial assets with the model for transactions in the new revenue standard. This amendment is effective for annual periods beginning after December 15, 2017. The Company does not expect this amendment to have a material effect on its financial statements.

In March 2017, the FASB issued ASU 2017-08, Receivables – Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization of Purchased Callable Debt Securities, which shortens the amortization period for the premium to the earliest call date. The amendment will be effective for the Company for interim and annual periods beginning after December 15, 2018. Early adoption is permitted. The Company does not expect this amendment to have a material effect on its financial statements.

In February 2018, the FASB issued ASU 2018-02, Income Statement – Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, which requires companies to reclassify the stranded effects in other comprehensive income to retained earnings as a result of the change in the tax rates under the Tax Cuts and Jobs Act (the 2017 Tax Act”). The Company has opted to early adopt this pronouncement by retrospective application to each period in which the effect of the change in the tax rate under the 2017 Tax Act is recognized. The impact of the reclassification from other comprehensive income to retained earnings is included in the Statement of Changes in Shareholders’ Equity.

We had $113.4 million and $101.2 million of loans pledged as collateral to secure funding with the Federal Reserve Bank (“FRB”) Discount Window at December 31, 2017 and 2016, respectively.

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.

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, where applicable.

● Good (2) The borrowing entity has dependable cash flow, better than average financial condition, good capital and 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, soft 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.

48

BANK OF SOUTH CAROLINA CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

● 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, 2017 and December 31, 2016. “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, 2017, there was one TDR with a balance of $33,300, compared to two TDRs with a total balance of $378,392 as of December 31, 2016, and three TDRs with a total balance of $458,268 as of December 31, 2015. These TDRs were granted extended payment terms with no principal reduction. All TDRs were performing as agreed as of December 31, 2017 and 2016, respectively. No TDRs that were modified within the previous twelve months defaulted during the years ended December 31, 2017 and 2016.

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 and 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 and offices, medical offices, and attorneys’ offices.

Our loans were concentrated in the following categories.

	December 31, 2017			December 31, 2016
Commercial		19.14	%		20.06	%
Commercial Real Estate Construction		0.86	%		0.46	%

We may, at our option, extend the lease of our Summerville office at 100 North Main Street for two additional ten-year periods; and extend the land lease where our Mt.

At December 31, 2017 and 2016, the Bank had unused short-term lines of credit totaling approximately $23.0 million and $21.0 million, respectively (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 includes 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.

The Company recognized the income tax effects of the 2017 Tax Act in its 2017 consolidated financial statements in accordance with Staff Accounting Bulletin No. 118, which provides SEC staff guidance for the application of ASC Topic 740, Income Taxes, in the reporting period in which the 2017 Tax Act was signed into law. As such, the Company’s financial results reflect the income tax effects of the 2017 Tax Act for which the accounting under ASC Topic 740 is incomplete but a reasonable estimate could be determined. The Company did not identify items for which the income tax effects of the 2017 Tax Act have not been completed and a reasonable estimate could not be determined as of December 31, 2017.

Total income taxes for the years ended December 31, 2017, 2016 and 2015 are presented in the table below.

	For the year ended December 31,
	2017			2016			2015

In 2016, the Company invested in a South Carolina Rehabilitation Credit. The tax credit is included in deferred tax assets and is being amortized. Amortization expense recognized for the years ended December 31, 2017 and 2016 was $306,105 and $325,000, respectively, and is included in other operating expense on the statement of operations.

There was a $67,253 valuation allowance for deferred tax assets at December 31, 2017 and $50,301 at December 31, 2016 associated with the Company’s state net operating loss. 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, 2017. 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.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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. Accordingly, the Company’s deferred tax assets and liabilities were remeasured to reflect the reduction in the U.S. corporate income tax rate from 34 percent to 21 percent, resulting in a $666,674 increase in income tax expense for the year ended December 31, 2017 and a corresponding $666,674 decrease in net deferred tax assets as of December 31, 2017.

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 2014 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 $92,869,285 and $81,234,269 at December 31, 2017 and 2016, 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. The majority of these standby letters of credit are unsecured. Commitments under standby letters of credit are usually for one year or less. At December 31, 2017 and 2016, 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, 2017 and 2016 was $1,219,644 and $793,992, 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 as of December 31, 2017 and 2016.

14. Stock Incentive Plan

We have a Stock Incentive Plan which was approved in 1998 with 180,000 (329,422 adjusted for three 10% stock dividends, a 10% stock distribution, and a 25% stock dividend) shares reserved and a Stock Incentive Plan which was approved in 2010 with 300,000 (330,000 adjusted for a 10% stock dividend) 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. 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 this 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.

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.

All relevant information has been retroactively adjusted for the 2015 10% stock dividend.

The total intrinsic value of options exercised during the years ended December 31, 2017, 2016, and 2015, were $311,836, $273,979, and $14,272, respectively.

We recognized compensation cost for the years ended December 31, 2017, 2016 and 2015 in the amount of $71,701, $76,529, and $78,987, respectively, related to the granted options.

As of December 31, 2017, there was a total of $284,123 in unrecognized compensation cost related to nonvested share-based compensation arrangements granted under the Plan. The cost is expected to be recognized over a weighted average period of 2.81 years.

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 $375,000 during the year ended December 31, 2017, $345,000 during the year ended December 31, 2016, and $315,000 for the year ended December 31, 2015. The plan currently owns 286,013 shares of common stock of Bank of South Carolina Corporation.

62

BANK OF SOUTH CAROLINA CORPORATION

 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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 $2,685,000, $2,340,000, and $2,475,000 to the Company during the years ended December 31, 2017, 2016 and 2015, respectively.

On August 27, 2015, the Company’s Board of Directors declared a ten percent stock dividend to our shareholders. The record date was September 8, 2015 and the distribution date was September 28, 2015. Earnings per share and average shares outstanding have been adjusted to reflect the stock dividend in our consolidated financial statements.

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.

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, 2017 and 2016.

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 capital conservation buffer in effect for the year ended December 31, 2017 was 1.25%.

At December 31, 2017, the Bank was categorized as “well capitalized” under Basel III. To be categorized as “well capitalized” the Bank must maintain minimum total risk based, Tier 1 risk based, common equity Tier 1 risk based capital and Tier 1 leverage ratios of 10.00%, 8.00%, 6.50% and 5.00%, respectively, and to be categorized as “adequately capitalized,” the Bank must maintain minimum total risk based, Tier 1 risk based, common equity Tier 1 risk based capital, and Tier 1 leverage ratios of 8.00%, 6.00%, 4.50%, and 4.00%, respectively.

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 that market participants would use in pricing an asset or liability are developed based on market data we have obtained from independent sources. 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 also would affect significantly 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 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. The fair value of these commitments was not significant at December 31, 2017 or 2016.

Assets and liabilities measured at fair value on a recurring basis at December 31, 2017 and December 31, 2016 are as follows:

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

OREO

Loans, secured by real estate, are adjusted to the lower of the recorded investment in the loan or the fair value of the real estate upon transfer to OREO. Subsequently, OREO is carried at the lower of carrying value or fair value. Fair value is based upon independent market prices, appraised values of the collateral or our estimation of the value of the collateral. When the fair value of the collateral is based on an observable market price or a current appraisal, we record the asset as nonrecurring Level 2. When an appraised value is not available or we determine the fair value of the collateral is further impaired below the appraised value and there is no observable market price, we record the asset as nonrecurring Level 3.

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. At December 31, 2017 and December 31, 2016, substantially all of the impaired loans were evaluated based on the fair value of the collateral. 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.

 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 carrying values of variable rate consumer and commercial loans and consumer and commercial loans with remaining maturities of three months or less, approximate fair value. The fair values of fixed rate consumer and commercial loans with maturities greater than three months are determined using a discounted cash flow analysis and assume the rate being offered on these types of loans at December 31, 2017 and December 31, 2016, approximate market.

The carrying value of mortgage loans held for sale approximates fair value. For lines of credit, the carrying value approximates fair value.

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.

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.

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, 2017 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, 2017, 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, 2017, 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, 2017. Based on this assessment, management believes that as of December 31, 2017, 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, 2017, 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 Compliance Officer, Risk Management Officer and Elliott Davis, LLC (separately and jointly) to discuss audit, financial and related matters. Elliott Davis, LLC, the Compliance Officer, and the Risk Management 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 preparation of the financial statements are 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, 2017 and 2016, respectively.

Interest-bearing Deposits at the Federal Reserve: 

Interest-bearing deposits at the Federal Reserve mature within one year 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 2017 and 2016.

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 uncollectibility 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 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 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, 2017, 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.

Other Real Estate Owned: 

Fair value is based upon independent market prices, appraised values of the collateral, or our estimation of the value of the collateral. Losses arising from an initial foreclosure are charged against the allowance for loan losses. Subsequent to foreclosure, other real estate owned (“OREO”) is recorded at the lower of cost or fair value, adjusted for net selling costs. Gains and losses on the sale of OREO and subsequent write-downs from periodic re-evaluation are charged to net other real estate owned expenses.

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, 2017 and 2016.

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 service period, generally defined as the vesting period (10 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 has, therefore, 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, 2017 and 2016.

We had no embedded derivative instruments requiring hedge accounting treatment at December 31, 2017. 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 May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers, Topic 606. The core principle of the new standard is that an entity should recognize revenue to reflect the transfer of goods and services to customers in an amount equal to the consideration the entity receives or expects to receive. This guidance also includes expanded disclosure requirements that result in an entity providing users of financial statements with comprehensive information about the nature, amount, timing, and uncertainty of revenue and cash flows arising from the entity’s contracts with customers. In August 2015, the FASB deferred the effective date of the amendments. As a result of the deferral, the guidance will be effective for the Company for reporting periods beginning after December 15, 2017. We will apply this guidance using a modified retrospective approach. Because the amendment does not apply to revenue associated with financial instruments, such as loans and investment securities available for sale, we do not expect this amendment to have a material effect on our consolidated financial statements. We are still evaluating the effects of the amendment regarding its applicability and related impact on credit card fees and deposit service charges.

In January 2016, the FASB issued ASU 2016-01, Financial Instruments – Overall (Subtopic 825-10); Recognition and Measurement of Financial Instruments and Financial Liabilities. This update addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. The amendments will be effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. We will apply the guidance by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. The amendments related to equity securities without readily determinable fair values will be applied prospectively to equity investments that exist as of the date of adoption of the amendments. The Company does not expect this amendment to have a material effect on its financial statements.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which revises certain aspects of recognition, measurement, presentation, and disclosure of leasing transactions. The amendments will be effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. We are currently evaluating the effect that implementation of the new standard will have on our results of operations and cash flows but expect the effect on the financial position to be considerable due to the fact that substantially all operating lease commitments will be recognized as right of use assets and lease liabilities based on the present value of unpaid lease payments as of the date of adoption.

In March 2016, the FASB issued ASU 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net), to clarify the implementation guidance on principal versus agent considerations and address how an entity should assess whether it is the principal or the agent in contracts that include three or more parties. The amendments will be effective for the Company for reporting periods beginning after December 15, 2017. The Company does not expect this amendment to have a material effect on its financial statements.

In March 2016, the FASB issued ASU 2016-09, Compensation – Stock Compensation (Topic 718): Improvements to Employee Share – Based Payment Accounting, to simplify several aspects of the accounting for share-based payment award transactions including the income tax consequences, the classification of awards as either equity or liabilities, and the classification on the statement of cash flows. Additionally, the guidance simplifies two areas specific to entities other than public business entities allowing them apply a practical expedient to estimate the expected term for all awards with performance or service conditions that have certain characteristics and also allowing them to make a one-time election to switch from measuring all liability-classified awards at fair value to measuring them at intrinsic value. The amendments became effective for the Company on January 1, 2017 and this amendment did not have a material effect on its financial statements.

In April 2016, the FASB issued ASU 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing, to clarify guidance related to identifying performance obligations and accounting for licenses of intellectual property. The amendments will be effective for the Company for reporting periods beginning after December 15, 2017. The Company does not expect these amendments to have a material effect on its financial statements.

In May 2016, the FASB issued ASU 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow- Scope Improvements and Practical Expedients, to clarify guidance related to collectability, noncash consideration, presentation of sales tax, and transition. The amendments will be effective for the Company for reporting periods beginning after December 15, 2017. The Company does not expect these amendments to have a material effect on its financial statements.

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. The amendments will be effective for the Company for reporting periods beginning after December 15, 2019. Early adoption is permitted for all organizations for periods beginning after December 15, 2018. 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.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, to clarify how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The amendments will be effective for the Company for fiscal years beginning after December 15, 2017 including interim periods within those fiscal years. Early adoption is permitted. The Company does not expect these amendments to have a material effect on its financial statements.

In December 2016, the FASB issued ASU 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers. These corrections make a limited number of revisions to several pieces of the revenue recognition standard issued in 2014. The effective date and transition requirements for the technical corrections will be effective for the Company for reporting periods beginning after December 15, 2017. The Company will continue to evaluate the impact of this ASU and does not expect these amendments to have a material effect on its financial statements.

In January 2017, the FASB issued ASU 2017-01, Clarifying the Definition of a Business, which provided guidance to assist with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The update is intended to address concerns that the existing definition of a business has been applied too broadly and has resulted in many transactions being recorded as business acquisitions that in substance are more akin to asset acquisitions. The amendments are effective for annual periods beginning after December 15, 2017, including interim periods within those periods. The amendments should be applied prospectively on or after the effective date. The Company does not expect this amendment to have a material effect on its financial statements.

In February 2017, the FASB issued ASU 2017-05, Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets, to clarify the scope of established guidance on nonfinancial asset derecognition, issued as part of ASU 2014-09, Revenue from Contracts with Customers, as well as accounting for partial sales of nonfinancial assets. The amendments conform the derecognition guidance on nonfinancial assets with the model for transactions in the new revenue standard. This amendment is effective for annual periods beginning after December 15, 2017. The Company does not expect this amendment to have a material effect on its financial statements.

In March 2017, the FASB issued ASU 2017-08, Receivables – Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization of Purchased Callable Debt Securities, which shortens the amortization period for the premium to the earliest call date. The amendment will be effective for the Company for interim and annual periods beginning after December 15, 2018. Early adoption is permitted. The Company does not expect this amendment to have a material effect on its financial statements.

In February 2018, the FASB issued ASU 2018-02, Income Statement – Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, which requires companies to reclassify the stranded effects in other comprehensive income to retained earnings as a result of the change in the tax rates under the Tax Cuts and Jobs Act (the 2017 Tax Act”). The Company has opted to early adopt this pronouncement by retrospective application to each period in which the effect of the change in the tax rate under the 2017 Tax Act is recognized. The impact of the reclassification from other comprehensive income to retained earnings is included in the Statement of Changes in Shareholders’ Equity.

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.

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, 2017 and 2016. 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 $113.4 million and $101.2 million of loans pledged as collateral to secure funding with the Federal Reserve Bank (“FRB”) Discount Window at December 31, 2017 and 2016, respectively.

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.

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, where applicable.

● Good (2) The borrowing entity has dependable cash flow, better than average financial condition, good capital and 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, soft 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, 2017 and December 31, 2016. “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, 2017, there was one TDR with a balance of $33,300, compared to two TDRs with a total balance of $378,392 as of December 31, 2016, and three TDRs with a total balance of $458,268 as of December 31, 2015. These TDRs were granted extended payment terms with no principal reduction. All TDRs were performing as agreed as of December 31, 2017 and 2016, respectively. No TDRs that were modified within the previous twelve months defaulted during the years ended December 31, 2017 and 2016.

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 and 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 and offices, medical offices, and attorneys’ offices.

Our loans were concentrated in the following categories.

INCOME TAXES

10. Income Taxes

On December 22, 2017, the President of the United States signed into law the 2017 Tax Act. The 2017 Tax Act includes 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.

The Company recognized the income tax effects of the 2017 Tax Act in its 2017 consolidated financial statements in accordance with Staff Accounting Bulletin No. 118, which provides SEC staff guidance for the application of ASC Topic 740, Income Taxes, in the reporting period in which the 2017 Tax Act was signed into law. As such, the Company’s financial results reflect the income tax effects of the 2017 Tax Act for which the accounting under ASC Topic 740 is incomplete but a reasonable estimate could be determined. The Company did not identify items for which the income tax effects of the 2017 Tax Act have not been completed and a reasonable estimate could not be determined as of December 31, 2017.

Total income taxes for the years ended December 31, 2017, 2016 and 2015 are presented in the table below.

	For the year ended December 31,
	2017			2016			2015

Net deferred tax assets	$	1,546,671		$	1,707,026

In 2016, the Company invested in a South Carolina Rehabilitation Credit. The tax credit is included in deferred tax assets and is being amortized. Amortization expense recognized for the years ended December 31, 2017 and 2016 was $306,105 and $325,000, respectively, and is included in other operating expense on the statement of operations.

There was a $67,253 valuation allowance for deferred tax assets at December 31, 2017 and $50,301 at December 31, 2016 associated with the Company’s state net operating loss. 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, 2017. 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. Accordingly, the Company’s deferred tax assets and liabilities were remeasured to reflect the reduction in the U.S. corporate income tax rate from 34 percent to 21 percent, resulting in a $666,674 increase in income tax expense for the year ended December 31, 2017 and a corresponding $666,674 decrease in net deferred tax assets as of December 31, 2017.

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 2014 and subsequent years are subject to examination by taxing authorities.

Commitments and Contingencies Disclosure [Abstract]

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 $92,869,285 and $81,234,269 at December 31, 2017 and 2016, 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. The majority of these standby letters of credit are unsecured. Commitments under standby letters of credit are usually for one year or less. At December 31, 2017 and 2016, 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, 2017 and 2016 was $1,219,644 and $793,992, respectively.

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 this 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.

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:

	2017			2016			2015
Risk free interest rate		2.43	%		2.33	%		1.96	%	2.33	%
Expected life (in years)		7.5			10			10		10
Expected stock price volatility		34.20	%		27.95	%		19.62	%	19.62	%
Dividend yield		4.00	%		3.47	%		4.13	%	4.13	%

There are currently options to purchase 1,600 shares outstanding and exercisable under the 1998 Omnibus Stock Incentive Plan with options to purchase 1,600 shares exercisable at December 31, 2017. This plan has expired, however, shares granted before the expiration date may still be exercised.

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 $375,000 during the year ended December 31, 2017, $345,000 during the year ended December 31, 2016, and $315,000 for the year ended December 31, 2015. The plan currently owns 286,013 shares of common stock of Bank of South Carolina Corporation.

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).

Dividends [Abstract]

DIVIDENDS

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 $2,685,000, $2,340,000, and $2,475,000 to the Company during the years ended December 31, 2017, 2016 and 2015, respectively.

On August 27, 2015, the Company’s Board of Directors declared a ten percent stock dividend to our shareholders. The record date was September 8, 2015 and the distribution date was September 28, 2015. Earnings per share and average shares outstanding have been adjusted to reflect the stock dividend in our consolidated financial statements.

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.

REGULATORY CAPITAL REQUIREMENTS

Regulatory Capital Requirements [Abstract]

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, 2017 and 2016.

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 capital conservation buffer in effect for the year ended December 31, 2017 was 1.25%.

At December 31, 2017, the Bank was categorized as “well capitalized” under Basel III. To be categorized as “well capitalized” the Bank must maintain minimum total risk based, Tier 1 risk based, common equity Tier 1 risk based capital and Tier 1 leverage ratios of 10.00%, 8.00%, 6.50% and 5.00%, respectively, and to be categorized as “adequately capitalized,” the Bank must maintain minimum total risk based, Tier 1 risk based, common equity Tier 1 risk based capital, and Tier 1 leverage ratios of 8.00%, 6.00%, 4.50%, and 4.00%, respectively.

The following tables present the actual and required capital amounts and ratios for the Company and Bank at December 31, 2017 and 2016:

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 that market participants would use in pricing an asset or liability are developed based on market data we have obtained from independent sources. 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 also would affect significantly 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 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. The fair value of these commitments was not significant at December 31, 2017 or 2016.

Assets and liabilities measured at fair value on a recurring basis at December 31, 2017 and December 31, 2016 are as follows:

December 31, 2017
	Quoted Market Price in active markets  (Level 1)		Significant Other Observable Inputs   (Level 2)		Significant Unobservable Inputs   (Level 3)		Total

The following table reconciles the changes in assets measured at fair value on a recurring basis using significant unobservable inputs (Level 3) for the years ended December 31, 2017 and 2016:

	December 31,

Ending balance	$	11,458,889		$	13,977,857

There were no transfers between fair value levels in 2017 or 2016.

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

OREO

Loans, secured by real estate, are adjusted to the lower of the recorded investment in the loan or the fair value of the real estate upon transfer to OREO. Subsequently, OREO is carried at the lower of carrying value or fair value. Fair value is based upon independent market prices, appraised values of the collateral or our estimation of the value of the collateral. When the fair value of the collateral is based on an observable market price or a current appraisal, we record the asset as nonrecurring Level 2. When an appraised value is not available or we determine the fair value of the collateral is further impaired below the appraised value and there is no observable market price, we record the asset as nonrecurring Level 3.

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. At December 31, 2017 and December 31, 2016, substantially all of the impaired loans were evaluated based on the fair value of the collateral. 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 a nonrecurring basis; that is, the instruments are not measured at fair value on an on going 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, 2017, and 2016.

There were no liabilities measured at fair value on a nonrecurring basis as of December 31, 2017 or 2016.

The following table provides information describing the unobservable inputs used in Level 3 fair value measurements at December 31, 2017:

	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
Other Real Estate Owned	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 carrying values of variable rate consumer and commercial loans and consumer and commercial loans with remaining maturities of three months or less, approximate fair value. The fair values of fixed rate consumer and commercial loans with maturities greater than three months are determined using a discounted cash flow analysis and assume the rate being offered on these types of loans at December 31, 2017 and December 31, 2016, approximate market.

The carrying value of mortgage loans held for sale approximates fair value. For lines of credit, the carrying value approximates fair value.

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.

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, 2017 and December 31, 2016.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)

12 Months Ended

Dec. 31, 2017

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 preparation of the financial statements are 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, 2017 and 2016, respectively.

Interest-bearing Deposits in Other Financial Institutions

Interest-bearing Deposits at the Federal Reserve: 

Interest-bearing deposits at the Federal Reserve mature within one year 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 2017 and 2016.

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 uncollectibility 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 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 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, 2017, 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.

Other Real Estate Owned

Other Real Estate Owned: 

Fair value is based upon independent market prices, appraised values of the collateral, or our estimation of the value of the collateral. Losses arising from an initial foreclosure are charged against the allowance for loan losses. Subsequent to foreclosure, other real estate owned (“OREO”) is recorded at the lower of cost or fair value, adjusted for net selling costs. Gains and losses on the sale of OREO and subsequent write-downs from periodic re-evaluation are charged to net other real estate owned expenses.

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, 2017 and 2016.

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 service period, generally defined as the vesting period (10 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 has, therefore, 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, 2017 and 2016.

We had no embedded derivative instruments requiring hedge accounting treatment at December 31, 2017. 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 May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers, Topic 606. The core principle of the new standard is that an entity should recognize revenue to reflect the transfer of goods and services to customers in an amount equal to the consideration the entity receives or expects to receive. This guidance also includes expanded disclosure requirements that result in an entity providing users of financial statements with comprehensive information about the nature, amount, timing, and uncertainty of revenue and cash flows arising from the entity’s contracts with customers. In August 2015, the FASB deferred the effective date of the amendments. As a result of the deferral, the guidance will be effective for the Company for reporting periods beginning after December 15, 2017. We will apply this guidance using a modified retrospective approach. Because the amendment does not apply to revenue associated with financial instruments, such as loans and investment securities available for sale, we do not expect this amendment to have a material effect on our consolidated financial statements. We are still evaluating the effects of the amendment regarding its applicability and related impact on credit card fees and deposit service charges.

In January 2016, the FASB issued ASU 2016-01, Financial Instruments – Overall (Subtopic 825-10); Recognition and Measurement of Financial Instruments and Financial Liabilities. This update addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. The amendments will be effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. We will apply the guidance by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. The amendments related to equity securities without readily determinable fair values will be applied prospectively to equity investments that exist as of the date of adoption of the amendments. The Company does not expect this amendment to have a material effect on its financial statements.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which revises certain aspects of recognition, measurement, presentation, and disclosure of leasing transactions. The amendments will be effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. We are currently evaluating the effect that implementation of the new standard will have on our results of operations and cash flows but expect the effect on the financial position to be considerable due to the fact that substantially all operating lease commitments will be recognized as right of use assets and lease liabilities based on the present value of unpaid lease payments as of the date of adoption.

In March 2016, the FASB issued ASU 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net), to clarify the implementation guidance on principal versus agent considerations and address how an entity should assess whether it is the principal or the agent in contracts that include three or more parties. The amendments will be effective for the Company for reporting periods beginning after December 15, 2017. The Company does not expect this amendment to have a material effect on its financial statements.

In March 2016, the FASB issued ASU 2016-09, Compensation – Stock Compensation (Topic 718): Improvements to Employee Share – Based Payment Accounting, to simplify several aspects of the accounting for share-based payment award transactions including the income tax consequences, the classification of awards as either equity or liabilities, and the classification on the statement of cash flows. Additionally, the guidance simplifies two areas specific to entities other than public business entities allowing them apply a practical expedient to estimate the expected term for all awards with performance or service conditions that have certain characteristics and also allowing them to make a one-time election to switch from measuring all liability-classified awards at fair value to measuring them at intrinsic value. The amendments became effective for the Company on January 1, 2017 and this amendment did not have a material effect on its financial statements.

In April 2016, the FASB issued ASU 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing, to clarify guidance related to identifying performance obligations and accounting for licenses of intellectual property. The amendments will be effective for the Company for reporting periods beginning after December 15, 2017. The Company does not expect these amendments to have a material effect on its financial statements.

In May 2016, the FASB issued ASU 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow- Scope Improvements and Practical Expedients, to clarify guidance related to collectability, noncash consideration, presentation of sales tax, and transition. The amendments will be effective for the Company for reporting periods beginning after December 15, 2017. The Company does not expect these amendments to have a material effect on its financial statements.

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. The amendments will be effective for the Company for reporting periods beginning after December 15, 2019. Early adoption is permitted for all organizations for periods beginning after December 15, 2018. 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.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, to clarify how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The amendments will be effective for the Company for fiscal years beginning after December 15, 2017 including interim periods within those fiscal years. Early adoption is permitted. The Company does not expect these amendments to have a material effect on its financial statements.

In December 2016, the FASB issued ASU 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers. These corrections make a limited number of revisions to several pieces of the revenue recognition standard issued in 2014. The effective date and transition requirements for the technical corrections will be effective for the Company for reporting periods beginning after December 15, 2017. The Company will continue to evaluate the impact of this ASU and does not expect these amendments to have a material effect on its financial statements.

In January 2017, the FASB issued ASU 2017-01, Clarifying the Definition of a Business, which provided guidance to assist with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The update is intended to address concerns that the existing definition of a business has been applied too broadly and has resulted in many transactions being recorded as business acquisitions that in substance are more akin to asset acquisitions. The amendments are effective for annual periods beginning after December 15, 2017, including interim periods within those periods. The amendments should be applied prospectively on or after the effective date. The Company does not expect this amendment to have a material effect on its financial statements.

In February 2017, the FASB issued ASU 2017-05, Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets, to clarify the scope of established guidance on nonfinancial asset derecognition, issued as part of ASU 2014-09, Revenue from Contracts with Customers, as well as accounting for partial sales of nonfinancial assets. The amendments conform the derecognition guidance on nonfinancial assets with the model for transactions in the new revenue standard. This amendment is effective for annual periods beginning after December 15, 2017. The Company does not expect this amendment to have a material effect on its financial statements.

In March 2017, the FASB issued ASU 2017-08, Receivables – Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization of Purchased Callable Debt Securities, which shortens the amortization period for the premium to the earliest call date. The amendment will be effective for the Company for interim and annual periods beginning after December 15, 2018. Early adoption is permitted. The Company does not expect this amendment to have a material effect on its financial statements.

In February 2018, the FASB issued ASU 2018-02, Income Statement – Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, which requires companies to reclassify the stranded effects in other comprehensive income to retained earnings as a result of the change in the tax rates under the Tax Cuts and Jobs Act (the 2017 Tax Act”). The Company has opted to early adopt this pronouncement by retrospective application to each period in which the effect of the change in the tax rate under the 2017 Tax Act is recognized. The impact of the reclassification from other comprehensive income to retained earnings is included in the Statement of Changes in Shareholders’ Equity.

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.
