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

•

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


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


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


•	fluctuations in the demand for loans, the number of unsold homes, land and other properties and fluctuations in real estate values in our market areas;


•	secondary market conditions for loans and our ability to sell loans in the secondary market;

•

results of examinations of the Company by the Board of Governors of the Federal Reserve System ("Federal Reserve") and the Bank by the Federal Deposit Insurance Corporation ("FDIC") and the South Carolina State Board of Financial Institutions ("State Board"), or other regulatory authorities, including the possibility that any such regulatory authority may, among other things, require us to increase our reserve for loan losses, write-down assets, change our regulatory capital position or affect our ability to borrow funds or maintain or increase deposits, or impose additional requirements or restrictions on us, any of which could adversely affect our liquidity and earnings;


•	legislative or regulatory changes that adversely affect our business, including the effect of the Dodd-Frank Wall Street Reform and Consumer Protection Act; changes in regulatory policies and principles, or the interpretation of regulatory capital requirements or other rules, including as a result of Basel III;


•	our ability to attract and retain deposits;


•	increases in premiums for deposit insurance;


•	our ability to control operating costs and expenses;


•	our ability to implement our business strategies;


•	the use of estimates in determining the fair value of certain of our assets, which estimates may prove to be incorrect and result in significant declines in valuation;


•	difficulties in reducing risk associated with the loans on our balance sheet;


•	staffing fluctuations in response to product demand or the implementation of corporate strategies that affect our workforce and potential associated charges;


•	disruptions, security breaches, or other adverse events, failures or interruptions in, or attacks on, our information technology systems or on the third-party vendors who perform several of our critical processing;


•	our ability to retain key members of our senior management team;


•	costs and effects of litigation, including settlements and judgments;


•	our ability to manage loan delinquency rates;


•	increased competitive pressures among financial services companies;


•	changes in consumer spending, borrowing and savings habits;


•	the availability of resources to address changes in laws, rules, or regulations or to respond to regulatory actions;


•	our ability to pay dividends on our common stock;


•	adverse changes in the securities markets;


•	inability of key third-party providers to perform their obligations to us;


•	changes in accounting policies and practices, as may be adopted by the financial institution regulatory agencies or the Financial Accounting Standards Board ("FASB"), including additional guidance and interpretation on accounting issues and details of the implementation of new accounting methods; and


•	other economic, competitive, governmental, regulatory, and technological factors affecting our operations, pricing, products and services and the other risks described elsewhere in this document.

These developments could have an adverse impact on our financial position and our results of operations.

Any of the forward-looking statements that we make may turn out to be wrong because of the inaccurate assumptions we might make because of the factors set forth above or because of other factors we cannot foresee. Because of these and other uncertainties, our actual future results may be materially different from those expressed in any forward-looking statements made by or on our behalf. Therefore, these factors should be considered in evaluating the forward-looking statements, and undue reliance should not be placed on such statements. We undertake no responsibility to update or revise any of these forward-looking statements.

As used throughout this report, the terms "we," "our," or "us" refer to Security Federal Corporation and our consolidated subsidiary, Security Federal Bank.

PART I

Item 1. Business

Security Federal Corporation

Security Federal Corporation (the "Company") was incorporated under the laws of the State of Delaware in July 1987 for the purpose of becoming the savings and loan holding company for Security Federal Bank ("Security Federal" or the "Bank") upon the Bank's conversion from mutual to stock form (the "Conversion"). Effective August 17, 1998, the Company changed its state of incorporation from Delaware to South Carolina. On December 28, 2011, the Company reorganized into a bank holding company in connection with the Bank's conversion from a federally chartered stock savings bank to a South Carolina chartered commercial bank. As a result of the reorganization, the Federal Reserve became the Company's primary federal regulator.

As a South Carolina corporation, the Company is authorized to engage in any activity permitted by South Carolina General Corporation Law. The Company is a one bank holding company. Through the bank holding company structure, it is possible to expand the size and scope of the financial services offered beyond those currently offered by the Bank. The holding company structure also provides the Company with greater flexibility than the Bank would have to diversify its business activities, through existing or newly formed subsidiaries, or through acquisitions or mergers of financial institutions as well as other companies. There are no current arrangements, understandings or agreements regarding any such acquisition. Future activities of the Company, other than the continuing operations of Security Federal, will be funded through dividends from Security Federal and through borrowings from third parties. See "Regulation - Regulation of the Company - Dividends" and "Taxation." Activities of the Company may also be funded through sales of additional securities or income generated by other activities of the Company. At this time, there are no plans regarding sales of additional securities or other activities.

At December 31, 2017 , the Company had assets of $868.8 million , deposits of $702.1 million and shareholders' equity of $77.9 million .

The executive office of the Company is located at 238 Richland Avenue Northwest, Aiken, South Carolina 29801, and its telephone number is (803) 641-3000.

Security Federal Bank

General . Security Federal is a South Carolina chartered commercial bank headquartered in Aiken, South Carolina. Security Federal, with 15 branch offices in Aiken, Richland and Lexington counties, South Carolina and Columbia County, Georgia, was originally chartered under the name Aiken Building and Loan Association on March 27, 1922. It received its federal charter and changed its name to Security Federal Savings and Loan Association of Aiken on March 7, 1962, and later changed its name to Security Federal Savings Bank of South Carolina, on November 11, 1986. Effective April 8, 1996, the Bank changed its name to Security Federal Bank. The Bank converted from the mutual to the stock form of organization on October 30, 1987. As mentioned above, effective December 28, 2011, Security Federal converted from a federally chartered stock savings bank to a South Carolina chartered commercial bank. As a result of the conversion to a South Carolina commercial bank, the Bank is regulated by the State Board and the FDIC. The Bank will open its 16th branch office in Ridge Spring, South Carolina in April 2018.

The principal business of Security Federal is accepting deposits from the general public and originating commercial real estate loans, commercial business loans, consumer loans, as well as mortgage loans to buy or refinance one-to-four family residential real estate. The Bank also originates construction loans on single-family residences, multi-family dwellings and projects, and commercial real estate, as well as loans for the acquisition, development and construction of residential subdivisions and commercial projects. In addition, the Bank operates Security Federal Trust and Investments, a division of the Bank that offers trust, financial planning and financial management services.

Security Federal has one active wholly owned subsidiary, Security Federal Insurance Inc., which is an insurance agency subsidiary that offers auto, business, health and home insurance. Security Federal Insurance also has a wholly owned subsidiary, Collier Jennings Financial Corporation, which has three wholly owned subsidiaries: Security Federal Auto Insurance, The Auto Insurance Store Inc., and Security Federal Premium Pay Plans Inc. Security Federal Premium Pay Plans Inc. has one wholly owned insurance premium finance subsidiary and also has an ownership interest in four other insurance premium finance subsidiaries. Security Federal also has one inactive subsidiary, Security Financial Services Corporation.

Security Federal's income is derived primarily from interest and fees earned in connection with its lending activities, and its principal expenses are interest paid on savings deposits and borrowings and operating expenses.

The Bank also originates construction loans on single family residences, multi-family dwellings and commercial real estate, and loans for the acquisition, development and construction of residential subdivisions and commercial projects.

In addition to interest earned on loans, the Bank receives loan origination fees or "points" for originating loans. Loan origination points are a percentage of the principal amount of the loan which are charged to the borrower for the creation of the loan. The Bank's loan origination fees are generally 1% on conventional residential mortgages, and 0.25% to 1% on commercial real estate loans and commercial business loans. Total fee income (including amounts amortized to income as yield adjustments) received by the Bank from loan originations was $617,000 for the year ended December 31, 2017 .

Loan origination and commitment fees are volatile sources of income. These fees vary with the volume and type of loans and commitments made and purchased and with competitive conditions in mortgage markets, which in turn are governed by the demand for and availability of money.

The following table shows deferred mortgage loan origination fees recognized as income by the Bank expressed as a percentage of the dollar amount of total mortgage loans originated (and retained in the Bank's portfolio) and purchased during the periods indicated and the dollar amount of deferred loan origination fees at the end of each respective period.

The Bank also receives other fees and charges related to existing loans, conversion fees, assumption fees, late charges and other fees collected in connection with a change in borrower or other loan modifications.

Security Federal currently sells substantially all conforming fixed rate loans with terms of 15 years or greater in the secondary mortgage market. These loans are sold in order to provide a source of funds and as one of the strategies available to close the gap between the maturities of the Bank's interest-earning assets and interest-bearing liabilities. Currently, most fixed rate, long-term mortgage loans are being originated based on Federal National Mortgage Association ("Fannie Mae") and Federal Home Loan Mortgage Corporation ("Freddie Mac") underwriting standards.

Secondary market sales are made to other banks or institutional investors. Generally all loans sold to investors are without recourse. For the past several years, substantially all loans have been sold on a servicing released basis. During the year ended December 31, 2017 , Security Federal sold $42.0 million in fixed rate residential loans on a servicing released basis in the secondary market. Loans closed but not yet settled with banks or other investors, are carried in the Bank's "loans held for sale" portfolio. At December 31, 2017 , the Bank had $3.1 million of loans held for sale. These loans are fixed rate residential loans that have been originated in the Bank's name and have closed. Virtually all of these loans have commitments to be purchased by investors and the majority of these loans were price locked with the investors on the same day or shortly after the loan was price locked with the Bank's customers. Therefore, these loans present very little market risk for the Bank. The Bank usually delivers loans to, and receives funding from, the investor within 30 days. Security Federal originates all of its loans held for sale on a "best efforts" basis which means that the Bank suffers no penalty if it is unable to deliver a loan to a potential investor.

Federal law restricts the Bank's permissible lending limits to one borrower to the greater of $500,000 or 15% of unimpaired capital and surplus. At December 31, 2017 , the Bank's legal lending limit under this restriction was $14.5 million. At that date, the Bank's largest loan relationship to a single borrower was $10.8 million. South Carolina law restricts the Bank's permissible lending limits to one borrower to 10% of unimpaired capital unless prior approval is granted by a two-thirds vote of the Board of Directors, in which case the limit is increased to 15% of unimpaired capital. During 2017 , the Board approved an increase in the Bank's lending limit to a single borrower to 15% of unimpaired capital.

Loan Solicitation and Processing . The Bank actively solicits mortgage loan applications from existing customers, real estate agents, builders, real estate developers and others. The Bank also receives mortgage loan applications as a result of customer referrals and from walk-in customers. Detailed loan applications are obtained to determine the borrower's creditworthiness and ability to repay. The more significant items on loan applications are verified through the use of credit reports, financial statements and confirmations. After analysis of the loan application and property or collateral involved, including an appraisal of the property (residential appraisals are obtained through independent fee appraisers), a lending decision is made in accordance with the underwriting guidelines of the Bank. These guidelines are generally consistent with Freddie Mac and Fannie Mae guidelines for residential real estate loans. With respect to commercial real estate loans, the Bank also reviews the capital adequacy of the business, the income potential of the property, the ability of the borrower to repay the loan and honor its other obligations, and general economic and industry conditions.

Upon receipt of a loan application and all required related information from a prospective borrower, the loan application is submitted for approval or rejection. The residential mortgage loan underwriters approve loans which meet Freddie Mac and Fannie Mae underwriting requirements. The Chairman of the Company, the Chief Executive Officer of the Company and the Bank, the President of the Bank, the Executive Vice President/Business Development, the Senior Vice President/Chief Lending Officer and Senior Vice President/Mortgage Lending individually have the authority to approve loans of $500,000 or less, except as set forth above for conforming conventionally underwritten, single family mortgage loans, which are approved by the underwriters. Loans in excess of $500,000 and up to $1.0 million require the approval of any three of the following: Chairman of the Company, the Chief Executive Officer of the Company and the Bank, the President of the Bank, the President of the Company, the Executive Vice President/Business Development, the Senior Vice President/Chief Lending Officer, the Vice Chairman of the Executive Committee or the Secretary of the Executive Committee. Any loan in excess of $1.0 million must be approved by the Bank's Executive Committee, which operates as the Bank's Loan Committee. The loan approval limits discussed above are the aggregate of all loans to any one borrower or entity, not including loans that are secured by the borrower's primary residence, and are conventionally underwritten.

The general policy of Security Federal is to issue loan commitments to qualified borrowers for a specified term, generally for a period of 45 days or less. With management approval, commitments may be extended for up to an additional 45 days. At December 31, 2017 , the Bank had $1.3 million in outstanding commitments on mortgage loans not yet closed compared to $165,000 at December 31, 2016. Security Federal had outstanding commitments available on all lines of credit (including letters of credit, commercial, undisbursed loans in process, home equity, VISA, and other consumer loans) totaling $91.4 million at December 31, 2017 . See Note 18 of the Notes to Consolidated Financial Statements contained in the Annual Report.

Residential Real Estate Lending . At December 31, 2017 the Bank had $84.3 million or 20.8% of the Bank's total outstanding loan portfolio in residential real estate loans. These loans can have adjustable or fixed rates and include permanent one- to four-family residential mortgage loans as well as construction loans for single family dwellings to owner-occupants.

Security Federal offers a variety of ARMs which offer adjustable rates of interest, payments, loan balances or terms to maturity which vary according to specified indices. The Bank's ARMs generally have a loan term of 15 to 30 years with initial rate adjustments every one, three, five or seven years during the term of the loan. After the initial rate adjustment, the loan rate then adjusts annually. Most of the Bank's ARMs contain a 200 basis point limit as to the maximum amount of change in the interest rate at any adjustment period and a 500 or 600 basis point limit over the life of the loan. The Bank generally originates ARMs to retain in its portfolio. These loans are generally made consistent with Freddie Mac and Fannie Mae guidelines. During the year ended December 31, 2017 , the Bank originated $63.7 million in residential real estate loans, 34.0% of which had adjustable interest rates. At December 31, 2017 , residential ARMs totaled $66.6 million or 16.4% of the Bank's loan portfolio. At December 31, 2017 , the Bank also held approximately $17.7 million or 4.3% of the loan portfolio in longer term fixed rate residential mortgage loans. Currently, the Bank sells the majority of its longer term fixed rate mortgage loans at origination.

There are unquantifiable risks resulting from possible increased costs to the borrower as a result of periodic repricing. Despite the benefits of ARMs to the Bank's asset/liability management program, these loans also pose potential additional risks, primarily because as interest rates rise, the underlying payment by the borrower rises, increasing the potential for default. At the same time, marketability of the underlying property may be adversely affected by higher interest rates.

When making a one- to four-family residential mortgage loan, the Bank evaluates both the borrower's creditworthiness and his or her general ability to make principal and interest payments, and the value of the property that will secure the loan. The Bank generally makes loans on one- to four-family residential properties in amounts of 95% or less of the appraised value of the collateral. When loans are made for amounts which exceed 80% of the appraised value of the underlying real estate, the Bank's general policy is to require private mortgage insurance on the portion of the loan in excess of 80% of the appraised value. In general, the Bank restricts its residential lending to South Carolina and the nearby Augusta, Georgia market.

Construction loans are generally made for periods of six months to one year with either adjustable or fixed rates. At December 31, 2017 , residential construction loans on one- to four-family dwellings to owner-occupants totaled $12.4 million , or 3.1%, of the Bank's loan portfolio. On loans of this type, the Bank seeks to evaluate the financial condition and prior performance of the builder, as well as the borrower's creditworthiness and his or her general ability to make principal and interest payments, and the value of the property that will secure the loan. On construction loans offered to individuals (non-builders), the Bank offers a construction/permanent loan. The one year construction portion of the loan has a fixed rate ranging currently from 2.75% to 5.88% depending on which ARM program the borrower has chosen for the permanent portion of the loan after the construction period. The borrower pays interest on the loan during the construction phase. After construction, the loan then automatically converts, depending on the borrower's upfront selection, to a one year ARM, a three year/one year ARM, or a five year/one year ARM loan in which the borrower will pay principal and interest. The borrower also has the option, after the construction period only, to convert the loan to a fixed rate residential mortgage loan which the Bank immediately sells on the secondary market on a servicing released basis.

Commercial Real Estate, Commercial Business and Multi-Family Loans . The commercial business loans originated by the Bank are primarily secured by business equipment, furniture and fixtures, inventory and receivables, or are unsecured. At December 31, 2017 , the Bank had $26.8 million , or 6.6 % of its total loan portfolio, in commercial business loans. A total of $962,000, or 3.6% of these loans were unsecured at December 31, 2017 .

The commercial real estate loans originated by the Bank are primarily secured by non-residential commercial properties, churches, hotels, residential developments, single family speculative dwellings or pre-sold homes, land lots, income property developments, and undeveloped land. At December 31, 2017 , the Bank had $237.8 million , or 58.6% of its total loan portfolio, in commercial real estate loans and multi-family loans. Included in these loans at December 31, 2017 was $23.7 million in A&D loans with terms of typically two to three years. Also included in commercial real estate loans was $14.6 million in loans for the construction of single family dwellings to builders with a term of typically one year.

Multi-family loans originated by the Bank are primarily secured by commercial residential properties including apartment complexes, condominiums or townhouses, and loans for acquisition and development of, or improvements to multi-family residential properties. At December 31, 2017 , the Bank had $9.0 million , or 2.2% of its total loan portfolio, in multi-family loans.

The following table summarizes the Bank's commercial real estate, multi-family, and commercial business loans by geographic market area at December 31, 2017 .

Loans secured by commercial real estate are typically written for amortization terms of 10 to 20 years. Commercial loans not secured by real estate are typically based on terms of three to 60 months. Both commercial real estate loans and commercial business loans not secured by real estate can be originated on adjustable or fixed rate terms. Adjustable rates are tied to the prime rate as quoted in The Wall Street Journal and typically adjust on a daily basis. Since 2009, the Bank has instituted floors of typically 4% to 6% on newly originated adjustable rate commercial business and commercial real estate loans. If ceilings are used, the loan will typically require a balloon payment in 60 months or less. Fixed rate loans on commercial real estate usually require a balloon payment in 36 to 60 months. Fixed rate loans on non-real estate collateral are generally amortizing in five years or less.

Commercial real estate lending entails significant additional credit risk when compared to residential lending. Commercial real estate loans typically involve large loan balances to single borrowers or groups of related borrowers. Because payments on loans secured by commercial properties often depend upon the successful operation and management of the properties, repayment of these loans may be affected by adverse conditions in the real estate market or the economy. In order to minimize the risks associated with this type of loan, the Bank generally limits the maximum loan-to-value ratio for commercial real estate to 65% to 80%, based on appraisals of the property at the time of the loan by appraisers designated by the Bank, and strictly scrutinizes the credit history, financial condition and cash flow of the borrower, the quality of the collateral and the expertise of management of the property securing the loan.

Although the creditworthiness of the business and its principals is of primary consideration, the underwriting process also includes a comparison of the value of the security, if any, in relation to the proposed loan amount. A&D loans secured by improved lots generally involve greater risks than residential mortgage lending because these loans are more difficult to evaluate. If the estimate of value proves to be inaccurate, in the event of default and foreclosure, we may be confronted with a property, the value of which is insufficient to assure full payment.

Commercial business lending generally involves greater risk than residential mortgage lending and involves risks that are different from those associated with lending that is secured by real estate. Real estate lending is generally considered to be collateral based lending with loan amounts based on predetermined loan-to-collateral values, and liquidation of the underlying real estate collateral is viewed as the primary source of repayment in the event of borrower default. Although commercial business loans often have equipment, inventory, accounts receivable or other business assets as collateral, the liquidation of collateral in the event of a borrower default is often not a sufficient source of repayment because accounts receivable may be uncollectible and inventories and equipment may be obsolete or of limited use, among other conditions. Accordingly, the repayment of a commercial business loan depends primarily on the creditworthiness of the borrower (and any guarantors), while liquidation of collateral is a secondary and often insufficient source of repayment. The Bank seeks to minimize these risks by strictly scrutinizing the borrower's current financial condition, ability to pay, past earnings and payment history. In addition, the current financial condition and payment history of all principals are reviewed. Typically, the Bank requires the principal or owners of a business to guarantee all loans made to their business by the Bank. Although the creditworthiness of the business and its principals is of primary consideration, the underwriting process also includes a comparison of the value of the security, if any, in relation to the proposed loan amount.

Consumer Loans . The Bank originates consumer loans for any personal, family or household purpose, including the financing of home improvements, loans to individuals for residential lots for a future home, automobiles, boats, mobile homes, recreational vehicles and education. The Bank also makes consumer first and second mortgage loans secured by residences. These loans typically do not qualify for sale in the secondary market, but are generally not considered sub-prime lending. In addition, the Bank offers home equity lines of credit. Home equity loans are secured by mortgage liens on the borrower's principal or second residence. Home equity lines are open end lines of credit where the borrowers pay a minimum of interest only monthly on drawn lines. The terms are for a maximum period of 20 years and the rate is a variable rate tied to prime and floats monthly. Margins range from none to one percent. In 2012, the Bank instituted interest rate floors, which currently range from 3.25% to 4.25%, on new originations and a maximum loan-to-value ratio of 80% if the first mortgage was originated by Security Federal and 70% if the first mortgage was originated by another lender. At December 31, 2017 , the Bank had $28.7 million of home equity lines of credit outstanding and $26.5 million of additional commitments of home equity lines of credit. The Bank also makes secured and unsecured lines of credit available. Although consumer loans involve a higher level of risk than one- to four-family residential mortgage loans, they generally provide higher yields and have shorter terms to maturity than one- to four-family residential mortgage loans. At December 31, 2017 , the Bank had $56.8 million , or 14.0 % of its loan portfolio, in consumer loans.

The Bank's underwriting standards for consumer loans include a determination of the applicant's payment history on other debts and an assessment of ability to meet existing obligations and payments on the proposed loan. The stability of the applicant's monthly income is determined by verification of gross monthly income from primary employment, and from any verifiable secondary income. Although creditworthiness of the applicant is of primary consideration, the underwriting process also includes a comparison of the value of the security, if any, in relation to the proposed loan amount.

The Bank also has a credit card program. As of December 31, 2017 , the Bank had issued 3,113 Visa credit cards with total approved credit lines of $7.8 million, of which $2.6 million was outstanding on that date.

Loan Delinquencies and Defaults

General . The Bank's collection procedures provide that when a real estate loan is approximately 20 days past due, the borrower is contacted by mail and payment is requested. If the delinquency continues for another 10 days, subsequent efforts are made to contact the delinquent borrower and establish a program to bring the loan current. In certain instances, the Bank may modify the loan or grant a limited moratorium on loan payments to enable the borrower to reorganize his financial affairs. If the loan continues in a delinquent status for 60 days or more, the Bank generally initiates foreclosure proceedings after the customer has been notified by certified mail. The Bank institutes the same collection procedure for its commercial real estate loans.

Delinquent Loans . The following table sets forth information concerning delinquent loans at December 31, 2017 .

Classified Assets . Federal regulations provide for the classification of loans and other assets such as debt and equity securities considered to be of lesser quality as "substandard," "doubtful" or "loss" assets. The regulations require commercial banks to classify their own assets and to establish prudent general allowances for loan losses for assets classified "substandard" or "doubtful." For the portion of assets classified as "loss," an institution is required to either establish specific allowances of 100% of the amount classified or charge off such amount. In addition, the State Board and/or FDIC may require the establishment of a general allowance for losses based on assets classified as "substandard" and "doubtful" or based on the general quality of the asset portfolio of a Bank. See "Regulation - Regulation of the Bank."

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

At December 31, 2017 , $11.7 million of the total loan balance were classified "substandard" compared to $12.9 million at December 31, 2016 . At December 31, 2017 , $23.8 million were designated as "special mention" compared to $19.3 million at December 31, 2016 . At December 31, 2017 , $60.1 million were designated as “caution” compared to $76.2 million at December 31, 2016 . The Bank had no loans classified as "doubtful" or "loss" at December 31, 2017 and 2016 . According to generally accepted accounting principles, the Bank is required to account for certain loan modifications or restructuring as a “troubled debt restructuring” ("TDRs"). In general, the modification or restructuring of a debt is considered a TDR if the Bank, for economic or legal reasons related to the borrower’s financial difficulties, grants a concession to the borrower that would not otherwise be considered. As of December 31, 2017 , there were $4.1 million in TDRs compared to $4.6 million at December 31, 2016 . The Bank's classification of assets is consistent with FDIC regulatory classifications.

Non-performing Assets . Loans are placed on non-accrual status when the collection of principal and/or interest becomes doubtful. In addition, all loans are placed on non-accrual status when the loan becomes 90 days or more contractually delinquent. All consumer loans more than 90 days delinquent are charged against the consumer loan allowance for loan losses unless there is adequate collateral which is in the process of being repossessed or foreclosed on. At December 31, 2017 , the Bank had $4.1 million in TDRs which involved restructuring the borrower's interest rate or principal on a loan or making other concessions on loans at a rate materially less than the market rate. Other loans of concern are those loans (not delinquent more than 60 days) that management has determined need to be closely monitored as the potential exists for increased risk on these loans in the future. Non-performing loans are reviewed monthly on a loan by loan basis. Charge-offs, whether partial or in full, associated with these loans will vary based on estimates of recovery for each loan.

The following table sets forth the amounts and categories of risk elements in the Bank's loan portfolio.

The balance in non-performing commercial real estate loans at December 31, 2017 consisted of 24 loans to 20 borrowers with an average loan balance of $139,000 compared to 20 loans to 17 borrowers with an average loan balance of $132,000 at December 31, 2016 . Of the non-performing commercial real estate loans at December 31, 2017 , $2.7 million consisted of 18 loans secured by commercial buildings or first mortgages on principal residences throughout the Bank's market area to 15 different borrowers. Loans secured by principal residences are considered commercial real estate if they were business purpose loans. The remaining non-performing commercial real estate loans at December 31, 2017 consisted of $19,000 for one acquisition and development loan; $288,000 for four loans secured by raw land to four separate borrowers; and $351,000 for one loan secured by a church building. At December 31, 2017 , our largest non-performing commercial real estate loan had a balance of $570,000 and was secured by a commercial building.

The largest decrease in non-performing loans was in the residential real estate loan category, which decreased $540,000 or 21.7% to $1.9 million at December 31, 2017 from $2.5 million at December 31, 2016 . Non-performing residential real estate loans at December 31, 2017 consisted of 14 loans to 14 borrowers with an average loan balance of $139,000, the largest of which was $427,000. At December 31, 2016 , non-performing residential real estate loans consisted of 17 loans to 17 borrowers with an average loan balance of $146,000, the largest of which was $352,000.

Also included in non-accruing loans at December 31, 2017 were nine consumer loans totaling $319,000 and two commercial business loans totaling $109,000. Of the nine consumer loans on non-accrual status at December 31, 2017 , the largest had a balance of $84,000.

At December 31, 2017 , there were no accruing loans equal to or more than 90 days delinquent. For the year ended December 31, 2017 , the interest income not recognized that would have been recognized with respect to non-accruing loans, had such loans been current in accordance with their original terms and with respect to TDRs, had such loans been current in accordance with their original terms, totaled $830,000 compared to $687,000 for the year ended December 31, 2016 . For the year ended December 31, 2017 actual interest recorded on these loans was $214,000 compared to $261,000 for the year ended December 31, 2016 .

Troubled Debt Restructurings . The Bank identifies and reviews all loans to be restructured based on an assessment of the borrower's credit status. This assessment is a continuous process that involves a review of the financial statements and prospects for repayment, payment delinquency, non-accrual status, and risk rating.

Not all loan modifications are TDRs. The Bank designates a loan modification as a TDR when the following two conditions are present: the borrower is experiencing financial difficulty, and because of this difficulty, the Bank grants a concession it would not otherwise consider. Typically these concessions involve a change in the interest rate, maturity date or payment amount or some combination of each. These concessions rarely result in the forgiveness of principal or interest. TDRs are considered impaired and are initially reported as non-performing loans on non-accrual status. Non-performing TDRs may be returned to accrual status when payment in full of all amounts due under the restructured terms is anticipated and the borrower has demonstrated a sustained payment history which is typically six months.

The Bank did not modify any loans that were considered to be TDRs during the year ended December 31, 2017 . The Bank had eight loans totaling $4.1 million at December 31, 2017 which were TDRs modified in prior years, compared to 12 loans totaling $4.6 million at December 31, 2016 . The eight TDRs consisted of one unsecured consumer loan with a balance of $17,000 and seven commercial real estate loans to six separate borrowers, the largest of which had a balance of $2.4 million at December 31, 2017 . The commercial real estate loans were secured primarily by first mortgages on one single family residence, two lots, one commercial building, one hotel and three churches.

At December 31, 2017 , two loans totaling $610,000 that had previously been restructured as TDRs were in default. Neither loan had been restructured within the last 12 months. All of the remaining TDRs were current at December 31, 2017 . The Bank considers any loan 30 days or more past due to be in default.

Potential Problem Loans. Potential problem loans include substandard loans that are not already included as non-accrual loans or TDRs and special mention loans where management has become aware of information regarding possible borrower credit issues that could potentially cause doubt about their ability to comply with current repayment terms. At December 31, 2017 and 2016 , the Bank had identified $29.7 million and $26.7 million, respectively, of potential problem loans through its internal loan review procedures.

Repossessed Assets . OREO had a balance of $1.1 million at December 31, 2017 and consisted of the following real estate properties: three single-family residences and 27 lots within residential subdivisions located throughout our market area in South Carolina; five parcels of commercial land and two commercial buildings in South Carolina.

Provision for Losses on Loans . Security Federal recognizes that it will experience credit losses during the course of making loans and that the risk of loss will vary with, among other things, the type of loan being made, the creditworthiness of the borrower over the term of the loan and, in the case of a secured loan, the quality of the underlying security for the loan. The Bank seeks to establish and maintain sufficient reserves for estimated losses on specifically identified loans and real estate where such losses can be estimated. Additionally, general reserves for estimated possible losses are established on specified portions of the Bank's portfolio such as consumer loans and higher risk residential construction mortgage loans based on management's estimate of the potential loss for loans which normally can be classified as higher risk. Specific and general reserves are based on, among other criteria: (1) the risk characteristics of the loan portfolio, (2) current economic conditions on a local as well as a statewide basis, (3) actual losses experienced historically and (4) the level of reserves for possible losses in the future.

At December 31, 2017 , the allowance for loan losses or reserve was $8.2 million . In determining the adequacy of the reserve for loan losses, management reviews past experience of loan charge-offs, the level of past due and non-accrual loans, the size and mix of the portfolio, general economic conditions in the market area, and individual loans to identify potential credit problems. Commercial business, commercial real estate and consumer loans were $321.4 million , or 79.2% of the total loan portfolio, at December 31, 2017 . Although these types of loans carry a higher level of credit risk than conventional residential mortgage loans, the level of reserves reflects management's continuing evaluation of this risk based on the Bank's past loss experience. At December 31, 2017 , the Bank's ratio of loans delinquent more than 60 days to total assets was 0.41%. The reserve is management's best estimate for offsetting risk for our estimated possible losses. There can be no guarantee that the estimate is adequate or accurate.

Management believes that reserves for loan losses are at a level adequate to provide for inherent loan losses. Although management believes that it has considered all relevant factors in its estimation of future losses, future adjustments to reserves may be necessary if conditions change substantially from the assumptions used in making the original estimations. Regulators will from time to time evaluate the allowance for loan losses which is subject to adjustment based upon the information available to the regulators at the time of their examinations.

The following table sets forth an analysis of the Bank's allowance for loan losses during the dates indicated.

Subsidiaries

At December 31, 2017 , Security Federal's net investment in its subsidiaries (including loans to subsidiaries) totaled $6.5 million. In addition to investments in subsidiaries, federal institutions are permitted to invest an unlimited amount in operating subsidiaries engaged solely in activities which a commercial bank may engage in directly.

Security Federal Insurance, Inc. ("SFINS") . SFINS, a wholly owned subsidiary of the Bank, is an insurance agency offering auto, business, health and home insurance, and premium finance. The operations of SFINS are included in the Company's Consolidated Financial Statements contained in the Annual Report.

Collier Jennings Financial Corporation . Collier Jennings Financial Corporation is a subsidiary of SFINS, a subsidiary of the Bank, which is described above. The Company acquired the insurance and insurance premium finance businesses of Collier Jennings Financial Corporation and its subsidiaries, Security Federal Auto Insurance, Inc., The Auto Insurance Store, Inc., and Security Federal Premium Pay Plans, Inc. (the "Collier-Jennings Companies"), effective June 30, 2006.

Investment Activities

Investment securities . The Bank has authority to invest in various types of liquid assets, including U.S. Treasury obligations and securities of various federal agencies, certificates of deposit at insured institutions, mutual funds, bankers' acceptances and federal funds. The Bank may also invest a portion of its assets in certain commercial paper and corporate debt securities. See "Regulation - Regulation of the Bank."

As a member of the Federal Home Loan Bank ("FHLB") System, Security Federal must maintain minimum levels of investments that are liquid assets as defined in Federal regulations. See "Regulation - Regulation of the Bank - Federal Home Loan Bank System." Liquidity may increase or decrease depending upon the availability of funds and comparative yields on investments in relation to the return on loans.

Historically, the Bank has maintained its liquid assets at a level believed adequate to meet requirements of normal daily activities, repayment of maturing debt and potential deposit outflows. Management regularly reviews and updates cash flow projections to assure that adequate liquidity is provided.

The following table sets forth the fair value of the Company's portfolio of securities and other investments, excluding mortgage-backed securities, at the dates indicated.

(1) Does not include mortgage-backed securities.

At December 31, 2017 , the Company did not have any investment securities (exclusive of obligations of the U.S. Government and federal agencies) issued by any one entity with a total book value in excess of 10% of its shareholders' equity. SBA bonds are backed by the full faith and credit of the U.S. government and carry a zero percent risk base when calculating risk based assets for regulatory capital purposes. Student Loan Pools are typically 97% guaranteed by the U.S. government. The FHLB, FFCB, Fannie Mae and Freddie Mac are government sponsored enterprises ("GSEs") and the securities and bonds issued by GSEs are not backed by the full faith and credit of the U.S. government.

The following table sets forth the maturities or repricing of investment securities, not including mortgage-backed securities, and FHLB stock at December 31, 2017 , and the weighted average yields of such securities and FHLB stock (calculated on the basis of the cost and effective yields weighted for the scheduled maturity of each security). Tax equivalent yields on tax exempt municipal bonds are calculated using a 34% tax rate. Callable securities are shown at their likely call dates based on current interest rates. The table was prepared using amortized cost. SBA bonds are based on maturity dates without the effect of scheduled payments or anticipated prepayments.

For information regarding the market value of the Bank's securities portfolios, see Notes 2 and 3 of the Notes to Consolidated Financial Statements contained in the Annual Report.

Mortgage-backed Securities . Security Federal has a portfolio of mortgage-backed securities in its portfolio. Mortgage-backed securities can serve as collateral for borrowings and, through repayments, as a source of liquidity. Under the Bank's risk-based capital requirement, mortgage-backed securities have a risk weight of 20% (or 0% in the case of Government National Mortgage Association ("Ginnie Mae") securities) compared to the 50% risk weight carried by residential loans.

The following table sets forth the composition of the mortgage-backed securities available for sale portfolio at fair value and the held to maturity portfolio at amortized cost at the dates indicated.

At December 31, 2017 , the Company did not have any mortgage-backed securities (exclusive of obligations of agencies of the U.S. Government) issued by any one entity with a total book value in excess of 10% of shareholders equity.

Freddie Mac and Fannie Mae mortgage-backed securities are GSE issued securities. GSE securities are not backed by the full faith and credit of the U.S. government. The private label CMO securities are issued by non-governmental real estate mortgage investment conduits, which are also not backed by the full faith and credit of the U.S. government. Ginnie Mae mortgage-backed securities are backed by the full faith and credit of the U.S. government.

For information regarding the market values of Security Federal's mortgage-backed securities portfolio, see Notes 2 and 3 of the Notes to Consolidated Financial Statements contained in the Annual Report.

Sources of Funds

Deposit accounts have traditionally been a principal source of the Bank's funds for use in lending and for other general business purposes. In addition to deposits, the Bank derives funds from loan repayments, cash flows generated from operations (including interest credited to deposit accounts), FHLB of Atlanta advances, borrowings from the Federal Reserve Bank of Atlanta ("Federal Reserve"), investment sales, the sale of securities under agreements to repurchase, and loan sales. See "Borrowings" below and Note 10 of the Notes to Consolidated Financial Statements contained in the Annual Report. Scheduled loan payments are a relatively stable source of funds while deposit inflows and outflows and the related cost of such funds have varied widely. FHLB of Atlanta advances, borrowings from the Federal Reserve Bank and the sale of securities under agreements to repurchase may be used on a short-term basis to compensate for seasonal reductions in deposits or deposit inflows at less than projected levels and may be used on a longer term basis in support of expanded lending activities. The availability of funds from loan and investment sales is influenced by general interest rates. See "Management's Discussion and Analysis of Financial Condition and Results of Operations" contained in the Annual Report.

Deposits . The Bank attracts both short-term and long-term deposits from the general public by offering a wide assortment of account types and rates. The Bank offers regular savings accounts, checking accounts, various money market accounts, fixed interest rate certificates with varying maturities, negotiated rate $100,000 or above jumbo certificates of deposit ("Jumbo CDs") and individual retirement accounts.

At December 31, 2017 , the Bank had $24.4 million in brokered deposits. The Bank believes that, based on its experience over the past several years, its savings and transaction accounts are stable sources of deposits.

The following table sets forth the deposit balances at the dates indicated.

The Bank relies upon locally obtained Jumbo CDs to maintain its deposit levels. At December 31, 2017 , Jumbo CDs constituted $139.7 million or 19.9% of the Bank's total deposits. At December 31, 2017 , the Bank held $43.4 million in public funds which consisted of $38.7 million in certificates of deposit and $4.7 million in demand deposit accounts.

Borrowings

As a member of the FHLB of Atlanta, the Bank is required to own capital stock in the FHLB of Atlanta and is authorized to apply for advances from the FHLB of Atlanta. Each FHLB credit program has its own interest rate, which may be fixed or variable, and range of maturities. The FHLB of Atlanta may prescribe the acceptable uses to which these advances may be utilized as well as limitations on the size of the advances and repayment provisions. At December 31, 2017 , the Bank had $51.7 million in outstanding advances from the FHLB of Atlanta. See Note 10 of the Notes to Consolidated Financial Statements contained in the Annual Report for information regarding the maturities and rate structure of the Bank's FHLB advances. Federal law contains certain collateral requirements for FHLB advances. See "Regulation - Regulation of the Bank - Federal Home Loan Bank System."

At December 31, 2017 , the Company had $5.2 million in junior subordinated debentures. The debentures accrue and pay distributions quarterly at a floating rate of three-month LIBOR plus 170 points which was equal to 3.29% at December 31, 2017 . The debentures were callable by the Company in September 2011, and quarterly thereafter, with a final maturity date of December 15, 2036. See Note 12 of the Notes to Consolidated Financial Statements contained in the Annual Report for more information.

On December 1, 2009, the Company issued $6.1 million in convertible senior debentures. The debentures will mature on December 1, 2029 and accrue interest at the rate of 8.0% per annum until maturity or earlier redemption or repayment. Interest on the debentures is payable on June 1 and December 1 of each year, commencing June 1, 2010. The debentures are convertible into the Company's common stock at a conversion price of $20 per share at the option of the holder at any time prior to maturity. The convertible senior debentures are redeemable, in whole or in part, at the option of the Company at any time on or after December 1, 2020, at a price equal to 100% of the principal amount of the debentures to be purchased plus any accrued and unpaid interest to, but excluding, the date of redemption. See Note 13 of the Notes to Consolidated Financial Statements contained in the Annual Report for more information.

On October 31, 2016, the Company repurchased all 22,000 shares of its Fixed Rate Cumulative Perpetual Preferred Stock, Series B (“Series B Preferred Stock”) from the United States Department of the Treasury (“U.S. Treasury”) for $21.3 million plus accrued but unpaid interest of $93,000 for a total payment of $21.4 million. In connection with this repurchase, the Company obtained a $14.0 million unsecured term loan from another financial institution. The loan will mature on October 1, 2019 and accrues and pays interest quarterly at a floating rate of the Wall Street Journal Prime index minus 30 basis points, which was equal to 4.20% at December 31, 2017 . See Note 11 of the Notes to Consolidated Financial Statements contained in the Annual Report for more information.

Competition

The Bank serves the counties of Aiken, Richland, and Lexington, South Carolina, and Columbia County, Georgia through its 15 full service branch offices located in Aiken, Ballentine, Clearwater, Columbia, Graniteville, Langley, Lexington, North Augusta, Wagener, and West Columbia, South Carolina, and Evans, Georgia.

Security Federal faces strong competition both in originating loans and in attracting deposits. Competition in originating loans comes primarily from other commercial banks, federal savings institutions, mortgage bankers and credit unions who also make loans in the Bank's market area. The Bank competes for loans principally on the basis of the interest rates and loan fees it charges, the types of loans it makes and the quality of services it provides to borrowers.

The Bank faces substantial competition in attracting deposits from federal savings institutions, commercial banks, money market and mutual funds, credit unions and other investment vehicles. The ability of the Bank to attract and retain deposits depends on its ability to provide an investment opportunity that satisfies the requirements of investors as to rate of return, liquidity, risk and other factors. The Bank attracts a significant amount of deposits through its branch offices primarily from the communities in which those branch offices are located. Therefore, competition for those deposits is principally from federal savings institutions and commercial banks located in the same communities. The Bank competes for these deposits by offering a variety of deposit accounts at competitive rates, convenient business hours, online/mobile services, and convenient branch locations with interbranch deposit and withdrawal privileges at each.

Personnel

At December 31, 2017 , the Company employed 202 full-time and 21 part-time employees. The Bank's employees are not represented by any collective bargaining agreement. Management of the Bank considers its relations with its employees to be good.

REGULATION

The following is a brief description of certain laws and regulations which are applicable to the Company and the Bank. Descriptions of laws and regulations here and elsewhere in this Form 10-K do not purport to be complete and are qualified in their entirety by reference to the actual laws and regulations. Legislation is introduced from time to time in the United States Congress or in the South Carolina State Legislature that may affect the operations of the Company and the Bank. In addition, the regulations governing the Company and the Bank may be amended from time to time by the State Board, the FDIC, the Federal Reserve, the SEC and the Consumer Protection Financial Bureau (“CFPB”). Any such legislation or regulatory changes in the future could have an adverse effect on our operations and financial condition. We cannot predict whether any such changes may occur.

As a bank holding company, the Company is subject to examination and supervision by, and is required to file certain reports with, the Federal Reserve. The Company also is subject to the rules and regulations of the SEC under the federal securities laws. The Bank, as a state-chartered commercial bank, is subject to regulation and oversight by the State Board, the applicable provisions of South Carolina law and by the regulations of the State Board adopted thereunder. The Bank also is subject to regulation and examination by the FDIC, which insures its deposits to the maximum extent permitted by law.

The laws and regulations affecting depository institutions and their holding companies have changed significantly particularly in connection with the enactment of The Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (“Dodd-Frank Act”). Among other changes, the Dodd-Frank Act established the CFPB as an independent bureau of the Federal Reserve. The CFPB assumed responsibility for the implementation of the federal financial consumer protection and fair lending laws and regulations and has authority to impose new requirements under these laws. The Bank is subject to consumer protection regulations issued by the CFPB, but as a smaller financial institution, the Bank is generally subject to supervision and enforcement by the FDIC and the State Board with respect to our compliance with federal and state consumer financial protection laws and regulations.

Many aspects of the Dodd-Frank Act are subject to delayed effective dates and/or rulemaking by the federal banking agencies. Their impact on operations cannot yet fully be assessed. The Dodd-Frank Act has resulted in, and may continue to result in, increased regulatory burden and increased compliance, operating and interest expense for the Bank, the Company and the financial services industry in general.

Regulation of the Bank

The Bank is an FDIC-insured, state-chartered commercial bank and is subject to various statutory requirements and rules and regulations promulgated and enforced primarily by the FDIC and the State Board. These statutes, rules, and regulations relate to insurance of deposits, required reserves, allowable investments, loans, mergers, consolidations, issuance of securities, payment of dividends, establishment of branches and other aspects of the business of the Bank. The FDIC has broad authority to prohibit the Bank from engaging in what it determines to be unsafe or unsound banking practices. In addition, federal law imposes a number of restrictions on state-chartered, FDIC-insured banks, and their subsidiaries. These restrictions cover many matters, examples of which include prohibitions against engaging as a principal in certain activities and the requirement of prior notification of branch closings. The Bank is not a member of the Federal Reserve System.

The Bank is required to file periodic reports with the FDIC and the State Board and is subject to periodic examinations and evaluations by those regulatory authorities. Based on these evaluations, the regulators may revalue the assets of an institution and require that it establish specific reserves to compensate for the differences between the determined value and the book value of these assets. The FDIC and the State Board may each accept the results of an examination by the other in lieu of conducting an independent examination.

Federal Deposit Insurance Corporation . The Deposit Insurance Fund ("DIF") of the FDIC insures deposits in the Bank up to $250,000 per separately insured depositor and such insurance is backed by the full faith and credit of the United States Government. As insurer, the FDIC imposes deposit insurance premiums (assessments) and is authorized to conduct examinations of and to require reporting by FDIC-insured institutions. For the year ended December 31, 2017 , the Bank paid $186,000 in FDIC premiums. The assessment base for these premiums is the Bank’s total average consolidated assets less average tangible capital.

Under the FDIC's regulations, assessment rates for small institutions (those with less than $10 billion in assets) are based on an institution's weighted average CAMELS component ratings and certain financial ratios. Initial base assessment rates range from 1.5 to 16 basis points for institutions with CAMELS composite ratings of 1 or 2, 3 to 30 basis points for those with a CAMELS composite score of 3, and 11 to 30 basis points for those with CAMELS composite scores of 4 or 5, all subject to certain adjustments. Assessment rates are expected to decrease in the future as the reserve ratio increases in specified increments to the 1.35% ratio required by the Dodd-Frank Act. Formerly, the required reserve ratio was 1.15%. Large institutions are assessed under a complex

scorecard method. The FDIC may increase or decrease its rates by 2 basis points without further rule-making. In an emergency, the FDIC may also impose a special assessment.

The Dodd-Frank Act directs the FDIC to offset the effects of higher assessments due to the increase in the reserve ratio on established small institutions by charging higher assessments to large institutions. To implement this mandate, large and highly complex institutions must pay an annual surcharge of 4.5 basis points on their assessment base beginning July 1, 2016. If the DIF reserve ratio has not reached 1.35% by December 31, 2018, the FDIC plans to impose a shortfall assessment on large institutions on March 31, 2019.

Since small institutions will be contributing to the DIF while the reserve ratio remains between 1.15% and 1.35% and the large institutions are paying a surcharge, the FDIC will provide assessment credits to small institutions for the portion of their assessments that contribute to the increase. When the reserve ratio reaches 1.38%, the FDIC will automatically apply an established small institution's assessment credits to reduce its regular deposit insurance assessments.

In addition to the assessment for deposit insurance, institutions are required to make payments on bonds issued in the late 1980s by the Financing Corporation to recapitalize a predecessor deposit insurance fund. These assessments, which may be revised based upon the level of DIF deposits, will continue until the bonds mature in the years 2017 through 2019. This payment is assessed quarterly and is an annual rate of 0.54 basis points of assessable assets for the quarter ended December 31, 2017 . For 2017 , the Bank incurred approximately $39,000 in these assessments.

The FDIC may terminate the deposit insurance of any insured depository institution if it determines after a hearing that the institution has engaged or is engaging in unsafe or unsound practices, is in an unsafe or unsound condition to continue operations, or has violated any applicable law, regulation, order or any condition imposed by an agreement with the FDIC. It also may suspend deposit insurance temporarily during the hearing process for the permanent termination of insurance if the institution has no tangible capital. If insurance of accounts is terminated, the accounts at the institution at the time of the termination, less subsequent withdrawals, shall continue to be insured for a period of six months to two years, as determined by the FDIC. Management is not aware of any existing circumstances which would result in termination of the Bank's deposit insurance.

A significant increase in insurance premiums would likely have an adverse effect on the operating expenses and results of operations of the Bank. There can be no prediction as to what changes in insurance assessment rates may be made in the future.

Prompt Corrective Action . Federal statutes establish a supervisory framework based on five capital categories: well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized and critically undercapitalized. An institution's category depends upon where its capital levels are in relation to relevant capital measures, which include risk-based capital measures, a common equity Tier 1 ("CET1") measure, a leverage ratio measure and certain other factors. The well-capitalized category is described below in "Capital Requirements". An institution that is not well capitalized is subject to certain restrictions on brokered deposits, including restrictions on the rates it can offer on its deposits, generally. Any institution which is neither well capitalized nor adequately capitalized is considered undercapitalized.

Undercapitalized institutions are subject to certain prompt corrective action requirements, regulatory controls and restrictions that become more extensive as an institution becomes more severely undercapitalized. Failure by institutions to comply with applicable capital requirements would, if unremedied, result in progressively more severe restrictions on their activities and lead to enforcement actions, including, but not limited to, the issuance of a capital directive to ensure the maintenance of required capital levels and, ultimately, the appointment of the FDIC as receiver or conservator. Banking regulators will take prompt corrective action with respect to depository institutions that do not meet minimum capital requirements. Additionally, approval of any regulatory application filed for review by the banking agencies may be dependent on compliance with capital requirements.

At December 31, 2017 , the Bank was categorized as "well capitalized" under the prompt corrective action regulations of the FDIC. For additional information, see "Capital Requirements" below and Note 15 of the Notes to Consolidated Financial Statements included in the Annual Report.

Capital Requirements . Effective January 1, 2015 (with certain provisions phased in over several years), the Company and the Bank became subject to new capital adequacy requirements adopted by the Federal Reserve and the FDIC, which created a new required ratio for CET1 capital, increased the minimum leverage and Tier 1 capital ratios, changed the risk-weightings of certain assets for purposes of the risk-based capital ratios, created an additional capital conservation buffer over the required capital ratios, and changed what qualifies as capital for purposes of meeting the capital requirements. These regulations implement the regulatory capital reforms required by the Dodd Frank Act and the “Basel III” requirements.

Under the capital regulations, the minimum capital ratios applicable to the Company and the Bank are: (1) a CET1 capital ratio of 4.5% of risk-weighted assets; (2) a Tier 1 capital ratio of 6.0% of risk-weighted assets; (3) a total risk-based capital ratio of 8.0% of risk-weighted assets; and (4) a leverage ratio (the ratio of Tier 1 capital to average total adjusted assets) of 4.0%. CET1 generally consists of common stock; retained earnings; accumulated other comprehensive income (“AOCI”) unless an institution elects to exclude AOCI from regulatory capital; and certain minority interests; all subject to applicable regulatory adjustments and deductions. Tier 1 capital generally consists of CET1 and noncumulative perpetual preferred stock. Tier 2 capital generally consists of other preferred stock and subordinated debt meeting certain conditions plus an amount of the allowance for loan and lease losses up to 1.25% of assets. In addition, Tier 1 capital includes accumulated other comprehensive income (loss), which includes all unrealized gains and losses on available for sale debt and equity securities. Because of the Bank's asset size, it was eligible for and elected to permanently opt-out of the inclusion of unrealized gains and losses on available for sale debt and equity securities in its capital calculations. Total capital is the sum of Tier 1 and Tier 2 capital.

In addition to the minimum capital requirements, the Bank must maintain a capital conservation buffer, which consists of additional CET1 capital greater than 2.5% of risk-weighted assets above the required minimum risk-based capital levels in order to avoid limitations on paying dividends, engaging in share repurchases, and paying discretionary bonuses based on percentages of eligible retained income that could be utilized for such actions. The phase-in of the capital conservation buffer requirement began on January 1, 2016, when a buffer greater than 0.625% of risk-weighted assets was required, which amount increases each year until the buffer requirement is fully implemented on January 1, 2019. At December 31, 2017 the Bank had more than sufficient CET1 capital to meet the capital conservation buffer requirement.

The regulations include the phasing-out of certain instruments as qualifying capital, including the deduction of mortgage servicing rights and certain deferred tax assets from regulatory capital, subject to a transaction period. The Bank does not have any of these instruments.

The risk-weights of certain assets for the calculation of risk-based ratios were increased to better reflect credit risk and other risk exposures. These include a 150% risk weight (up from 100%) for certain high volatility commercial real estate acquisition, development and construction loans and for non-residential mortgage loans that are 90 days or more past due or otherwise on non-accrual status; a 20% (up from 0%) credit conversion factor for the unused portion of a commitment with an original maturity of one year or less that is not unconditionally cancellable; and a 250% risk weight (up from 100%) for mortgage servicing rights and deferred tax assets that are not deducted from capital.

To be considered well-capitalized, a depository institution must have a CET1 risk-based capital ratio of at least 6.5%, a Tier 1 risk-based capital ratio of 8.0%, a total risk-based capital ratio of 10.0% and a Tier 1 leverage ratio of at least 5.0%. At December 31, 2017 , the Bank met the requirements to be "well capitalized" and met the fully phased-in capital conservation buffer requirement. Management monitors the capital levels of the Bank to provide for current and future business opportunities and to meet regulatory guidelines for “well capitalized” institutions.

The FDIC has the authority to establish individual minimum capital requirements in appropriate cases upon a determination that an institution's capital level is or may become inadequate in light of particular risks or circumstances. Management of the Bank believes that, under the current regulations, the Bank will continue to meet its minimum capital requirements in the foreseeable future. For a complete description of the Bank's required and actual capital levels on December 31, 2017 , see Note 15 of the Notes to Consolidated Financial Statements included in the Annual Report.

Federal Home Loan Bank System . The Bank is a member of the FHLB of Atlanta, which is one of 11 regional FHLBs that administer the home financing credit function of financial institutions. The FHLBs are subject to the oversight of the Federal Housing Finance Agency and each FHLB serves as a reserve or central bank for its members within its assigned region. The FHLBs are funded primarily from proceeds derived from the sale of consolidated obligations of the FHLB System and makes loans or advances to members in accordance with policies and procedures established by the Board of Directors of the FHLB, which are subject to the oversight of the Federal Housing Finance Board. All advances from the FHLB are required to be fully secured by sufficient collateral as determined by the FHLB. In addition, all long-term advances are required to provide funds for residential home financing. At December 31, 2017 , the Bank had $51.7 million of outstanding advances from the FHLB of Atlanta under an available credit facility of $258.3 million, which is limited to available collateral. See "Business - Sources of Funds - Borrowings."

As a member, the Bank is required to purchase and maintain stock in the FHLB of Atlanta. At December 31, 2017, the Bank had $2.9 million in FHLB stock, which was in compliance with this requirement. In past years, the Bank has received substantial dividends on its FHLB stock. These dividend yields have averaged 4.96% for the year ended December 31, 2017; 4.70% for the year ended December 31, 2016; and 4.40% for the year ended December 31, 2015.

The FHLBs continue to contribute to low- and moderately-priced housing programs through direct loans or interest subsidies on advances targeted for community investment and low- and moderate-income housing projects. These contributions have in the past affected adversely the level of FHLB dividends paid and could continue to do so in the future. These contributions could also have an adverse effect on the value of FHLB stock in the future. A reduction in value of the Bank's FHLB stock may result in a corresponding reduction in the Bank's capital.

Affiliate Transactions . The Company and the Bank are separate and distinct legal entities. Federal laws strictly limit the ability of banks to engage in certain transactions with their affiliates, including their bank holding companies. Transactions deemed to be a "covered transaction" under Section 23A of the Federal Reserve Act and between a subsidiary bank and its parent company or the nonbank subsidiaries of the bank holding company are limited to 10% of the bank subsidiary's capital and surplus and, with respect to the parent company and all such nonbank subsidiaries, to an aggregate of 20% of the bank subsidiary's capital and surplus. Further, covered transactions that are loans and extensions of credit generally are required to be secured by eligible collateral in specified amounts. Federal law also requires that covered transactions and certain other transactions listed in Section 23B of the Federal Reserve Act between a bank and its affiliates be on terms as favorable to the bank as transactions with non-affiliates.

Community Reinvestment Act . The Bank is also subject to the provisions of the Community Reinvestment Act of 1977, which requires the appropriate federal bank regulatory agency to assess a bank's record in meeting the credit needs of the community serviced by the bank, including low and moderate income neighborhoods. The regulatory agency's assessment of the bank's record is made available to the public. Further, the regulatory agency considers the performance of a bank under the Act when determining whether to approve certain applications, including applications to establish a new branch office that will accept deposits, relocate an existing office or merge or consolidate with, or acquire the assets or assume the liabilities of, a federally regulated financial institution. The Bank received an "outstanding" rating during its most recent examination.

Dividends . Dividends from the Bank constitute the major source of funds for dividends which may be paid by the Company to shareholders. The amount of dividends payable by the Bank to the Company depends upon the Bank's earnings and capital position, and is limited by federal and state laws, regulations and policies, including the capital conservation buffer requirement discussed above. South Carolina banking regulations restrict the amount of dividends that the Bank can pay to the Company, and may require prior approval before declaration and payment of any excess dividend.

The amount of dividends actually paid during any one period will be strongly affected by the Bank's management policy of maintaining a strong capital position. Federal law further provides that no insured depository institution may pay a cash dividend if it would cause the institution to be "undercapitalized," as defined in the prompt corrective action regulations. Moreover, the federal bank regulatory agencies also have the general authority to limit the dividends paid by insured banks if such payments should be deemed to constitute an unsafe and unsound practice.

Activities and Investments of Insured State-Chartered Financial Institutions . Federal law generally limits the activities and equity investments of FDIC-insured, state-chartered banks to those that are permissible for national banks. An insured state bank is not prohibited from, among other things, (i) acquiring or retaining a majority interest in a subsidiary, (ii) investing as a limited partner in a partnership the sole purpose of which is direct or indirect investment in the acquisition, rehabilitation or new construction of a qualified housing project, provided that such limited partnership investments may not exceed 2% of the bank's total assets, (iii) acquiring up to 10% of the voting stock of a company that solely provides or reinsures directors', trustees' and officers' liability insurance coverage or bankers' blanket bond group insurance coverage for insured depository institutions, (iv) acting as agent for a customer in many capacities, and (v) acquiring or retaining the voting shares of a depository institution if certain requirements are met.

Federal Reserve System . The Federal Reserve requires that all depository institutions maintain reserves on transaction accounts or non-personal time deposits. These reserves may be in the form of cash or non-interest-bearing deposits with the regional Federal Reserve Bank. Negotiable order of withdrawal (NOW) accounts and other types of accounts that permit payments or transfers to third parties fall within the definition of transaction accounts and are subject to the reserve requirements, as are any non-personal time deposits at a savings bank. As of December 31, 2017 , the Bank's deposit with the Federal Reserve Bank and vault cash exceeded its reserve requirements.

Standards for Safety and Soundness . The federal banking regulatory agencies have prescribed, by regulation, guidelines for all insured depository institutions relating to internal controls, information systems and internal audit systems; loan documentation; credit underwriting; interest rate risk exposure; asset growth; asset quality; earnings; and compensation, fees and benefits. The 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. Each insured depository institution must implement a comprehensive written information security program that includes administrative, technical, and physical safeguards appropriate

to the institution’s size and complexity and the nature and scope of its activities. The information security program must be designed to ensure the security and confidentiality of customer information, protect against any unanticipated threats or hazards to the security or integrity of such information, protect against unauthorized access to or use of such information that could result in substantial harm or inconvenience to any customer, and ensure the proper disposal of customer and consumer information. Each insured depository institution must also develop and implement a risk-based response program to address incidents of unauthorized access to customer information in customer information systems. If the FDIC determines that an institution fails to meet any of these guidelines, it may require an institution to submit to the FDIC an acceptable plan to achieve compliance.

Environmental Issues Associated with Real Estate Lending . The Comprehensive Environmental Response, Compensation and Liability Act ("CERCLA"), a federal statute, generally imposes strict liability on all prior and present "owners and operators" of sites containing hazardous waste. However, Congress acted to protect secured creditors by providing that the term "owner and operator" excludes a person whose ownership is limited to protecting its security interest in the site. Since the enactment of the CERCLA, this "secured creditor exemption" has been the subject of judicial interpretations which have left open the possibility that lenders could be liable for cleanup costs on contaminated property that they hold as collateral for a loan. To the extent that legal uncertainty exists in this area, all creditors, including the Bank, that have made loans secured by properties with potential hazardous waste contamination (such as petroleum contamination) could be subject to liability for cleanup costs, which costs often substantially exceed the value of the collateral property.

Privacy Standards . The Gramm-Leach-Bliley Financial Services Modernization Act of 1999 (“GLBA”) modernized the financial services industry by establishing a comprehensive framework to permit affiliations among commercial banks, insurance companies, securities firms and other financial service providers. The Bank is subject to FDIC regulations implementing the privacy protection provisions of the GLBA. These regulations require the Bank to disclose its privacy policy, including informing consumers of its information sharing practices and informing consumers of their rights to opt out of certain practices.

Other Consumer Protection Laws and Regulations . The Dodd-Frank Act established the CFPB and empowered it to exercise broad regulatory, supervisory and enforcement authority with respect to both new and existing consumer financial protection laws. The Bank is subject to consumer protection regulations issued by the CFPB, but as a financial institution with assets of less than $10 billion, the Bank is generally subject to supervision and enforcement by the FDIC and the State Board with respect to our compliance with federal and state consumer financial protection laws and regulations.

The Bank is subject to a broad array of federal and state consumer protection laws and regulations that govern almost every aspect of its business relationships with consumers. While the list set forth below is not exhaustive, these include the Truth-in-Lending Act, the Truth in Savings Act, the Electronic Fund Transfer Act, the Expedited Funds Availability Act, the Equal Credit Opportunity Act, the Fair Housing Act, the Real Estate Settlement Procedures Act, the Home Mortgage Disclosure Act, the Fair Credit Reporting Act, the Fair Debt Collection Practices Act, the Right to Financial Privacy Act, the Home Ownership and Equity Protection Act, the Consumer Leasing Act, the Fair Credit Billing Act, the Homeowners Protection Act, the Check Clearing for the 21st Century Act, laws governing flood insurance, laws governing consumer protections in connection with the sale of insurance, federal and state laws prohibiting unfair and deceptive business practices, and various regulations that implement some or all of the foregoing. These laws and regulations mandate certain disclosure requirements and regulate the manner in which financial institutions must deal with customers when taking deposits, making loans, collecting loans, and providing other services. Failure to comply with these laws and regulations can subject the Bank to various penalties, including but not limited to, enforcement actions, injunctions, fines, civil liability, criminal penalties, punitive damages, and the loss of certain contractual rights.

Regulation of the Company

General . The Company, as the sole shareholder of the Bank, is a registered bank holding company with the Federal Reserve. Bank holding companies are subject to comprehensive regulation by the Federal Reserve under the Bank Holding Company Act of 1956, as amended ("BHCA"), and the regulations promulgated thereunder. This regulation and oversight is generally intended to ensure that the Company limits its activities to those allowed by law and that it operates in a safe and sound manner without endangering the financial health of the Bank.

As a bank holding company, the Company is required to file with the Federal Reserve semi-annual and periodic reports and such additional information as the Federal Reserve may require and is subject to regular examinations by the Federal Reserve. The Federal Reserve may examine the Company, and any of its subsidiaries, and charge the Company for the cost of the examination. The Federal Reserve also has extensive enforcement authority over bank holding companies, including, among other things, the ability to assess civil money penalties, to issue cease and desist or removal orders and to require that a holding company divest subsidiaries (including its bank subsidiaries). In general, enforcement actions may be initiated for violations of law and regulations and unsafe or unsound practices.

The Bank Holding Company Act . Under the BHCA, the Company is supervised by the Federal Reserve. The Federal Reserve has a policy that a bank holding company is required to serve as a source of financial and managerial strength to its subsidiary banks and may not conduct its operations in an unsafe or unsound manner. In addition, the Dodd-Frank Act and earlier Federal Reserve policy provide that a bank holding company should serve as a source of strength to its subsidiary bank by having the ability to provide financial assistance to its subsidiary bank during periods of financial distress to the bank, and should maintain the financial flexibility and capital raising capacity to obtain additional resources for assisting its subsidiary bank. A bank holding company's failure to meet its obligation to serve as a source of strength to its subsidiary banks will generally be considered by the Federal Reserve to be an unsafe and unsound banking practice or a violation of the Federal Reserve's regulations or both. No regulations have yet been proposed by the Federal Reserve to implement the source of strength provisions of the Dodd-Frank Act. The Company and any subsidiaries that it may control are considered "affiliates" within the meaning of the Federal Reserve Act, and transactions between the Bank and affiliates (except subsidiaries of the Bank) are subject to numerous restrictions. With some exceptions, the Company and its subsidiaries, are prohibited from tying the provision of various services, such as extensions of credit, to other services offered by the Company, or by its affiliates.

Acquisitions . The BHCA prohibits a bank holding company, with certain exceptions, from acquiring direct or indirect ownership or control of more than 5% of the voting shares of any company that is not a bank or bank holding company and from engaging directly or indirectly in activities other than those of banking, managing or controlling banks, or providing services for its subsidiaries. Under the BHCA, the Federal Reserve is authorized to approve the ownership of shares by a bank holding company in any company, the activities of which the Federal Reserve has determined to be so closely related to the business of banking or managing or controlling banks as to be a proper incident thereto. The list of activities determined by regulation to be closely related to banking within the meaning of the BHCA includes, among other things: operating a savings institution, mortgage company, finance company, credit card company or factoring company; performing certain data processing operations; providing certain investment and financial advice; underwriting and acting as an insurance agent for certain types of credit-related insurance; leasing property on a full-payout, non-operating basis; selling money orders, travelers' checks and U.S. Savings Bonds; real estate and personal property appraising; providing tax planning and preparation services; and, subject to certain limitations, providing securities brokerage services for customers.

Capital Requirements . Bank holding companies are subject to capital adequacy requirements of the Federal Reserve under the BHCA and the regulations of the Federal Reserve. For a bank holding company with less than $1.0 billion in assets, the capital guidelines apply on a bank only basis and the Federal Reserve expects the holding company's subsidiary bank to be well-capitalized under the prompt corrective action regulations. If the Company had been subject to regulatory guidelines for bank holding companies with $1.0 billion or more in assets, at December 31, 2017 , it would have exceeded all regulatory capital requirements. For additional information, see Note 15 of the Notes to Consolidated Financial Statements included in the Annual Report.

Interstate Banking . The Federal Reserve may approve an application of a bank holding company to acquire control of, or acquire all or substantially all of the assets of, a bank located in a state other than such holding company's home state, without regard to whether the transaction is prohibited by the laws of any state except with respect to the acquisition of a bank that has not been in existence for the minimum time period, not exceeding five years, specified by the law of the host state. The Federal Reserve may not approve an application if the applicant controls or would control more than 10% of the insured deposits in the United States or 30% or more of the deposits in the target bank's home state or in any state in which the target bank maintains a branch. Federal law does not affect the authority of states to limit the percentage of total insured deposits in the state that may be held or controlled by a bank holding company to the extent such limitation does not discriminate against out-of-state banks or bank holding companies. Individual states may also waive the 30% state-wide concentration limit contained in the federal law.

The federal banking agencies are authorized to approve interstate merger transactions without regard to whether such transaction is prohibited by the law of any state, unless the home state of one of the banks adopted a law prior to June 1, 1997 which applies equally to all out-of-state banks and expressly prohibits merger transactions involving out-of-state banks. Interstate acquisitions of branches will be permitted only if the law of the state in which the branch is located permits such acquisitions. Interstate mergers and branch acquisitions are also subject to the nationwide and statewide insured deposit concentration amounts described above. De novo interstate branching banks are generally permissible, subject to application requirements.

Dividends . As a South Carolina corporation, the Company is subject to restrictions on the payment of dividends under South Carolina law. In addition, the Company is an entity separate and distinct from its principal subsidiary, Security Federal Bank, and derives substantially all of its revenue in the form of dividends from this subsidiary. Accordingly, the Company is, and will be, dependent upon dividends from the Bank to pay the principal of and interest on its indebtedness, to satisfy its other cash needs and to pay dividends on its common stock. The Company is also subject to certain federal regulatory considerations. The Federal Reserve has issued a policy statement on the payment of cash dividends by bank holding companies, which expresses the Federal Reserve's view that a bank holding company should pay cash dividends only to the extent that the company's net income

for the past year is sufficient to cover both the cash dividends and a rate of earnings retention that is consistent with the company's capital needs, asset quality and overall financial condition, and that it is inappropriate for a company experiencing serious financial problems to borrow funds to pay dividends. Dividends are also subject to restriction if the capital conservation buffer requirement is not met.

Stock Repurchases . Bank holding companies, except for certain "well-capitalized" and highly rated bank holding companies, are required to give the Federal Reserve prior written notice of any purchase or redemption of its outstanding equity securities if the consideration for the purchase or redemption, when combined with the net consideration paid for all such purchases or redemptions during the preceding 12 months, is equal to 10% or more of their consolidated net worth. The Federal Reserve may disapprove a purchase or redemption if it determines that the proposal would constitute an unsafe or unsound practice or would violate any law, regulation, Federal Reserve order, or any condition imposed by, or written agreement with, the Federal Reserve.

Federal Securities Laws . The Company’s common stock is registered with the SEC under Section 12(b) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). We are subject to information, proxy solicitation, insider trading restrictions and other requirements under the Exchange Act.

The Dodd-Frank Act . On July 21, 2010, the Dodd-Frank Act was signed into law. The Dodd-Frank-Act imposed new restrictions and an expanded framework of regulatory oversight for financial institutions, including depository institutions and implements new capital regulations that the Company and the Bank are subject to and that are discussed above under the section entitled “- Regulation of the Bank - Capital Requirements.”

In addition, among other changes, the Dodd-Frank Act requires public companies, like the Company, to (i) provide their shareholders with a non-binding vote (a) at least once every three years on the compensation paid to executive officers and (b) at least once every six years on whether they should have a “say on pay” vote every one, two or three years; (ii) have a separate, non-binding shareholder vote regarding golden parachutes for named executive officers when a shareholder vote takes place on mergers, acquisitions, dispositions or other transactions that would trigger the parachute payments; (iii) provide disclosure in annual proxy materials concerning the relationship between the executive compensation paid and the financial performance of the issuer; and (iv) amend Item 402 of Regulation S-K to require companies to disclose the ratio of the Chief Executive Officer's annual total compensation to the median annual total compensation of all other employees. For certain of these changes, the implementing regulations have not been promulgated, so the full impact of the Dodd-Frank Act on public companies cannot be determined at this time.

Sarbanes-Oxley Act of 2002 . As a public company that files periodic reports with the SEC under the Exchange Act, the Company is subject to the Sarbanes-Oxley Act of 2002 (“Sarbanes-Oxley Act”), which addresses, among other issues, corporate governance, auditing and accounting, executive compensation and enhanced and timely disclosure of corporate information. The Sarbanes-Oxley Act represents significant federal involvement in matters traditionally left to state regulatory systems, such as the regulation of the accounting profession, and to state corporate law, such as the relationship between a board of directors and management and between a board of directors and its committees. Our policies and procedures have been updated to comply with the requirements of the Sarbanes-Oxley Act.

Jumpstart Our Business Startups ("JOBS") Act . The JOBS Act was signed into law on April 5, 2012 and allows banks and bank holding companies to terminate the registration of a class of securities under Section 12(g) and Section 12(b) of the Exchange Act if such class is held of record by less than 1,200 persons, an increase from the prior 300 person threshold. The SEC issued proposed rules on August 29, 2012 and on December 18, 2014 and has also mandated rules under Title III of the JOBS Act. The Company's Board continues to evaluate the costs and advantages and disadvantages of being an SEC registered company and the affects of deregistering its shares of common stock, including among other things, the resulting decrease in the liquidity of its shares.

TAXATION

Federal Taxation

General . The Company and the Bank report their income on a calendar year basis using the accrual method of accounting and are subject to federal income taxation in the same manner as other corporations with some exceptions, including particularly the Bank's reserve for bad debts discussed below. The following discussion of tax matters is intended only to summarize certain pertinent federal income tax matters and is not a comprehensive description of the tax rules applicable to the Bank or the Company.

On December 22, 2017, the U.S. Government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the "Tax Act"). The Tax Act amends the Internal Revenue Code to reduce tax rates and modify policies, credits, and deductions for individuals and businesses. For businesses, the Tax Act reduces the corporate federal income tax rate from a maximum of 35% to a flat 21% rate. The corporate income tax rate reduction was effective January 1, 2018. The Tax Act required a revaluation the Company’s deferred tax assets and liabilities to account for the future impact of lower corporate income tax rates and other provisions of the legislation. As a result of the Company's revaluation, the net deferred tax asset was reduced by $606,000 through an increase to the provision for income taxes of the same amount.

Distributions . To the extent that the Bank makes "nondividend distributions" to the Company, these distributions will be considered to result in distributions from the balance of its bad debt reserve as of December 31, 1987 (or a lesser amount if the Bank's loan portfolio decreased since December 31, 1987) and then from the supplemental reserve for losses on loans ("Excess Distributions"), and an amount based on the Excess Distributions will be included in the Bank's taxable income. Nondividend distributions include distributions in excess of the Bank's current and accumulated earnings and profits, distributions in redemption of stock and distributions in partial or complete liquidation. However, dividends paid out of the Bank's current or accumulated earnings and profits, as calculated for federal income tax purposes, will not be considered to result in a distribution from the Bank's bad debt reserve. The amount of additional taxable income created from an Excess Distribution is an amount that, when reduced by the tax attributable to the income, is equal to the amount of the distribution. Thus, if the Bank makes a "nondividend distribution," then approximately one and one-half times the Excess Distribution would be includable in gross income for federal income tax purposes, assuming a 34% corporate income tax rate (exclusive of state and local taxes). See "Regulation - Regulation of the Bank - Dividends” for limits on the payment of dividends by the Bank. The Bank does not intend to pay dividends that would result in a recapture of any portion of its tax bad debt reserve.

Corporate Alternative Minimum Tax . The Internal Revenue Code imposes a tax on alternative minimum tax at a rate of 20% on a base of regular taxable income plus certain tax preferences, called alternative minimum taxable income. The alternative minimum tax is payable to the extent such alternative minimum taxable income is in excess of an exemption amount. Net operating losses can offset no more than 90% of alternative minimum taxable income. Certain payments of alternative minimum tax may be used as credits against regular tax liabilities in future years. The Company did not have an alternative minimum tax credit carryforward at December 31, 2017 .

Net Operating Loss Carryovers . A financial institution may carry back net operating losses to the preceding two taxable years and forward to the succeeding 20 taxable years. This provision applies to losses incurred in taxable years beginning after August 2009. As of December 31, 2017 , management determined it is more likely than not that the total deferred tax asset will be realized except for the deferred tax asset associated with state net operating loss carryforwards, and, accordingly, has established a valuation allowance only for this item. The change in the valuation allowance was $69,000 .

Dividends-Received Deduction . The Company may exclude from its income dividends received from the Bank as a wholly-owned subsidiary of the Company that files a consolidated return with the Bank. The corporate dividends-received deduction is 100%, or 80%, in the case of dividends received from corporations with which a corporate recipient does not file a consolidated tax return, depending on the level of stock ownership of the payer of the dividend. Corporations that own less than 20% of the stock of a corporation distributing a dividend may deduct 70% of dividends received or accrued on their behalf.

Audits . The Company, the Bank and its consolidated subsidiaries have been audited or their books closed without audit by the IRS with respect to consolidated federal income tax returns through March 31, 2013. See Note 14 of the Notes to Consolidated Financial Statements contained in the Annual Report for additional information regarding income taxes.

State Taxation

South Carolina has adopted the Internal Revenue Code as it relates to commercial banks, effective for taxable years beginning after December 31, 1986. The Bank is subject to South Carolina income tax at the rate of 4.5%. The Bank has not been audited by the State of South Carolina during the past five years. The Company's income tax returns have not been audited by federal or state authorities within the last five years. For additional information regarding income taxes, see Note 14 of the Notes to Consolidated Financial Statements contained in the Annual Report.

Item 1A. Risk Factors.

An investment in our common stock involves various risks which are particular to Security Federal Corporation, our industry, and our market area. Before making an investment decision, you should carefully consider the risks and uncertainties described below, together with all of the other information included in this report and out filings with the SEC. In addition to the risks and uncertainties described below, other risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially and adversely affect our business, financial condition, capital levels, liquidity, cash flows, results of operations and prospects. The market price of our common stock could decline significantly due to any of these identified or other risks, and you could lose some or all of your investment.

Risks Related to our Business

Our business may be adversely affected by downturns in the national economy and in the economies in our market areas.

Our operations are significantly affected by the general economic conditions of the states of South Carolina and Georgia and the specific local markets in which we operate. Our entire real estate portfolio consists primarily of loans secured by properties located in Aiken, Richland, and Lexington Counties in South Carolina and Columbia and Richmond Counties in Georgia. A decline in the economies of these five counties in which we operate, which we consider to be our primary market area, could have a material adverse effect on our business, financial condition, results of operations, and prospects.

While real estate values and unemployment rates have recently improved, a deterioration in economic conditions in the market areas we serve could result in loan losses beyond that which is provided for in our allowance for loan losses and could result in the following consequences, any of which could have a materially adverse effect on our business, financial condition, or results of operations:


•	loan delinquencies, problem assets and foreclosures may increase;


•	we may increase our allowance for loan losses;


•	demand for our products and services may decline, possibly resulting in a decrease in our total loans or assets;


•	collateral for our loans, especially real estate, may decline in value, exposing us to increased risk of loss on existing loans, reducing customers’ borrowing power, and reducing the value of assets and collateral associated with existing loans;


•	the net worth and liquidity of loan guarantors may decline, impairing their ability to honor commitments to us; and


•	the amount of our low-cost or noninterest-bearing deposits may decrease

A decline in local economic conditions may have a greater effect on our earnings and capital than on the earnings and capital of larger financial institutions whose real estate loan portfolios are geographically diverse. Many of the loans in our portfolio are secured by real estate. Deterioration in the real estate markets where collateral for a mortgage loan is located could negatively affect the borrower’s ability to repay the loan and the value of the collateral securing the loan. Real estate values are affected by various other factors, including changes in general or regional economic conditions, governmental rules or policies and natural disasters such as earthquakes. If we are required to liquidate a significant amount of collateral during a period of reduced real estate values, our financial condition and profitability could be adversely affected. Adverse changes in the regional and general economy could reduce our growth rate, impair our ability to collect loans and generally have a negative effect on our financial condition and results of operations.

Our allowance for loan losses may prove to be insufficient to absorb losses in our loan portfolio.

Lending money is a substantial part of our business and each loan carries a certain risk that it will not be repaid in accordance with its terms or that any underlying collateral will not be sufficient to assure repayment. This risk is affected by, among other things:


•	cash flow of the borrower and/or the project being financed;


•	the changes and uncertainties as to the future value of the collateral, in the case of a collateralized loan;


•	the duration of the loan;


•	the character and creditworthiness of a particular borrower; and


•	changes in economic and industry conditions.

We maintain an allowance for loan losses, which is a reserve established through a provision for loan losses charged to expense, which we believe is appropriate to provide for probable losses in our loan portfolio. The amount of this allowance is determined by our management through periodic reviews and consideration of several factors, including, but not limited to:


•	our general reserve, based on our historical default and loss experience and certain macroeconomic factors based on management's expectations of future events;


•	our specific reserve, based on our evaluation of impaired loans and their underlying collateral; and


•	an unallocated reserve to provide for other credit losses inherent in our portfolio that may not have been contemplated in the other loss factors.

The determination of the appropriate level of the allowance for loan losses inherently involves a high degree of subjectivity and requires us to make significant estimates of current credit risks and future trends, all of which may undergo material changes. If our estimates are incorrect, the allowance for loan losses may not be sufficient to cover losses inherent in our loan portfolio, resulting in the need for additions to our allowance through an increase in the provision for loan losses. Deterioration in economic conditions affecting borrowers, new information regarding existing loans, identification of additional problem loans and other factors, both within and outside of our control, may increase our loan charge-offs and/or may otherwise require an increase in the allowance for loan losses. Our allowance for loan losses was 2.08% of total loans outstanding and 120.3% of non-performing loans at December 31, 2017 . In addition, bank regulatory agencies periodically review our allowance for loan losses and may require us to increase our provision for loan losses or recognize additional loan charge-offs. Any increases in the provision for loan losses may result in a decrease in net income and may have a material adverse effect on our financial condition, results of operations and capital.

If our non-performing assets increase, our earnings will be adversely affected.

At December 31, 2017 , our non-performing assets (which consist of non-accruing loans and OREO) were $6.8 million, or 0.8% of total assets. Our non-performing assets adversely affect our net income in various ways:


•	we record interest income only on a cash basis for nonaccrual loans and any non-performing investment securities;


•	we do not record interest income for OREO;


•	we provide for probable loan losses through a current period charge to the provision for loan losses;


•	non-interest expense increases when we write down the value of properties in our OREO portfolio to reflect changing market values or recognize other-than-temporary impairment on non-performing investment securities;


•	there are legal fees associated with the resolution of problem assets, as well as carrying costs, such as taxes, insurance, and maintenance fees related to our OREO; and


•	the resolution of non-performing assets requires the active involvement of management, which can distract them from more profitable activity.

If additional borrowers become delinquent and do not pay their loans and we are unable to successfully manage our non-performing assets, our losses and troubled assets could increase significantly, which could have a material adverse effect on our financial condition and results of operations.

Our level of commercial and multifamily real estate loans may expose us to increased lending risks.

At December 31, 2017 , commercial and multifamily real estate loans were $237.8 million or 58.6% of our total loan portfolio. The credit risk related to these types of loans is considered to be greater than the risk related to one-to-four-family residential loans because the repayment of commercial and multi-family real estate loans typically is dependent on the successful operation and income stream of the property securing the loan and the value of the real estate securing the loan as collateral, which can be significantly affected by changes in the economy or local market conditions. In addition, some of our commercial real estate loans are not fully amortizing and contain large balloon payments upon maturity. These balloon payments may require the borrower to either sell or refinance the underlying property in order to make the balloon payment, which may increase the risk of default or non-payment. These loans also generally have relatively large balances to single borrowers or related groups of borrowers. Accordingly, if we make any errors in judgment in the collectability of our commercial real estate loans, any resulting charge-offs may be larger on a per loan basis than those incurred with our residential or consumer loan portfolios. Consequently, this could materially adversely affect our future earnings. Finally, if foreclosure occurs on a commercial real estate loan, the holding period for the collateral, if any, typically is longer than for a one-to-four-family residence because the secondary market for most types of commercial and multi-family real estate is not readily liquid, so we have less opportunity to mitigate credit risk by selling part or all of our interest in these assets.

Our construction and land loans are based upon estimates of costs and the value of the completed project.

We originate construction loans on single-family residences, multi-family dwellings and projects, and commercial real estate, as well as loans for the acquisition and development ("A&D") and construction of residential subdivisions and commercial projects. We originate these loans whether or not the collateral property underlying the loan is under contract for sale. At December 31, 2017, commercial construction and A&D loans totaled $72.2 million or 17.8% of our total loan portfolio.

At that date, A&D loans were $23.7 million or 5.8% of our total loan portfolio. At December 31, 2017 , included in our commercial real estate loan portfolio was $14.6 million, or 3.6% of our total loan portfolio, in loans for the speculative construction of single family dwellings to builders. At December 31, 2017 , our residential loan portfolio included $12.4 million or 3.1% of our total loan portfolio of owner occupied residential loans.

Construction and A&D lending involves additional risks when compared with permanent residential lending because funds are advanced upon the collateral for the project based on an estimate of costs that will produce a future value at completion. Because of the uncertainties inherent in estimating construction costs, as well as the market value of the completed project and the effects of governmental regulation on real property, it is relatively difficult to evaluate accurately the total funds required to complete a project and the completed project loan-to-value ratio. Changes in the demand, such as for new housing and higher than anticipated building costs, may cause actual results to vary significantly from those estimated. For these reasons, this type of lending also typically involves higher loan principal amounts and is often concentrated with a small number of builders. A downturn in housing, or the real estate market, could increase loan delinquencies, defaults and foreclosures, and significantly impair the value of our collateral and our ability to sell the collateral upon foreclosure. Some of our builders have more than one loan outstanding with us and also have residential mortgage loans for rental properties with us. Consequently, an adverse development with respect to one loan or one credit relationship can expose us to a significantly greater risk of loss.

In addition, during the term of most of our commercial construction loans, no payment from the borrower is required since the accumulated interest is added to the principal of the loan through an interest reserve. As a result, these loans often involve the disbursement of funds with repayment substantially dependent on the success of the ultimate project and the ability of the borrower to sell or lease the property or obtain permanent take-out financing, rather than the ability of the borrower or guarantor to repay principal and interest. If our appraisal of the value of a completed project proves to be overstated, we may have inadequate security for the repayment of the loan upon completion of construction of the project and may incur a loss. Because construction loans require active monitoring of the building process, including cost comparisons and on-site inspections, these loans are more difficult and costly to monitor. Increases in market rates of interest may have a more pronounced effect on construction loans by rapidly increasing the end-purchasers’ borrowing costs, thereby reducing the overall demand for the project. Properties under construction are often difficult to sell and typically must be completed in order to be successfully sold which also complicates the process of working out problem construction loans. This may require us to advance additional funds and/or contract with another builder to complete construction. Furthermore, in the case of speculative construction loans, there is the added risk associated with identifying an end-purchaser for the finished project. Land loans also pose additional risk because of the lack of income being produced by the property and the potential illiquid nature of the collateral. These risks can also be significantly impacted by supply and demand conditions.

A&D loans pose additional risk because of the lack of income being produced by the property and the potential illiquid nature of the collateral. These risks can be significantly impacted by supply and demand conditions. As a result, this type of lending often involves the disbursement of substantial funds with repayment dependent on the success of the ultimate project and the ability of the borrower to develop, sell or lease the property, rather than the ability of the borrower or guarantor to independently repay principal and interest. There was one non-performing A&D loan with a balance of $19,000 at December 31, 2017. A material increase in our non-performing construction and development loans could have a material adverse effect on our financial condition and results of operation.

Repayment of our commercial business loans is often dependent on the cash flows of the borrower, which may be unpredictable, and the collateral securing these loans may fluctuate in value.

At December 31, 2017 , $26.8 million or 6.6% of our total loans were commercial business loans. Commercial business lending involves risks that are different from those associated with residential and commercial real estate lending. Real estate lending is generally considered to be collateral based lending with loan amounts based on predetermined loan to collateral values and liquidation of the underlying real estate collateral being viewed as the primary source of repayment in the event of borrower default. Our commercial business loans are primarily made based on the cash flow of the borrower and secondarily on the underlying collateral provided by the borrower. The borrowers' cash flow may be unpredictable, and collateral securing these loans may fluctuate in value. Although commercial business loans are often collateralized by equipment, inventory, accounts receivable, or other business assets, the liquidation of collateral in the event of default is often an insufficient source of repayment because accounts receivable may be uncollectible and inventories may be obsolete or of limited use, among other things. Accordingly, the repayment of commercial business loans depends primarily on the cash flow and credit worthiness of the borrower and secondarily on the underlying collateral provided by the borrower.

The level of our commercial real estate loan portfolio may subject us to additional regulatory scrutiny.

The FDIC, the Federal Reserve and the Office of the Comptroller of the Currency, have promulgated joint guidance on sound risk management practices for financial institutions with concentrations in commercial real estate lending. Under the guidance, a financial institution that, like us, is actively involved in commercial real estate lending should perform a risk assessment to identify concentrations. A financial institution may have a concentration in commercial real estate lending if, among other factors, (i) total reported loans for construction, land acquisition and development, and other land represent 100% or more of total capital or (ii) total reported loans secured by multi-family and non-farm residential properties, loans for construction, land acquisition and development and other land, and loans otherwise sensitive to the general commercial real estate market, including loans to commercial real estate related entities, represent 300% or more of total capital. The particular focus of the guidance is on exposure to commercial real estate loans that are dependent on the cash flow from the real estate held as collateral and that are likely to be at greater risk to conditions in the commercial real estate market (as opposed to real estate collateral held as a secondary source of repayment or as an abundance of caution). The purpose of the guidance is to guide banks in developing risk management practices and capital levels commensurate with the level and nature of real estate concentrations. The guidance states that management should employ heightened risk management practices including board and management oversight and strategic planning, development of underwriting standards, risk assessment and monitoring through market analysis and stress testing. Regulatory scrutiny of commercial real estate is generally at a ratio of 300% or more. At December 31, 2017 , total commercial real estate loans represented 252% of risk based capital plus the excess allowance for loan losses. While we believe we have implemented policies and procedures with respect to our commercial real estate loan portfolio consistent with this guidance, bank regulators could require us to implement additional policies and procedures consistent with their interpretation of the guidance that may result in additional costs to us.

Declines in property values have increased loan-to-value ratios on a significant portion of our one- to four-family loans and home equity lines of credit, which exposes us to greater risk of loss.

Many of our one- to four-family loans and home equity lines of credit are secured by liens on mortgage properties in which the borrowers have little or no equity because of the declines in home values in our primary market area. Residential loans with high combined loan-to-value ratios will be more sensitive to declining property values than those with lower combined loan-to-value ratios and therefore may experience a higher incidence of default and severity of losses. In addition, if the borrowers sell their homes, they may be unable to repay their loans in full from the sale proceeds. Further, the majority of our home equity lines of credit consist of second mortgage loans. For those home equity lines secured by a second mortgage, it is unlikely that we will be successful in recovering all or a portion of our loan proceeds in the event of default unless we are prepared to repay the first mortgage loan and such repayment and the costs associated with a foreclosure are justified by the value of the property. For these reasons, these loans may experience higher rates of delinquencies, defaults and losses.

Our real estate lending also exposes us to the risk of environmental liabilities.

In the course of our business, we may foreclose and take title to real estate, and we could be subject to environmental liabilities with respect to these properties. We may be held liable to a governmental entity or to third persons for property damage, personal injury, investigation, and clean-up costs incurred by these parties in connection with environmental contamination, or may be required to investigate or clean up hazardous or toxic substances, or chemical releases at a property. The costs associated with investigation or remediation activities could be substantial. In addition, as the owner or former owner of a contaminated site, we may be subject to common law claims by third parties based on damages and costs resulting from environmental contamination emanating from the property. If we ever become subject to significant environmental liabilities, our business, financial condition and results of operations could be materially and adversely affected.

If our investments in real estate are not properly valued or sufficiently reserved to cover actual losses, or if we are required to increase our valuation reserves, our earnings could be reduced.

We obtain updated valuations in the form of appraisals and broker price opinions when a loan has been foreclosed upon and the property taken in as OREO, and at certain other times during the assets holding period. Our net book value in the loan at the time of foreclosure and thereafter is compared to the updated market value of the foreclosed property less estimated selling costs (fair value). A charge-off is recorded for any excess in the asset's net book value over its fair value. If our valuation process is incorrect, or if the property declines in value after foreclosure, the fair value of our investments in OREO may not be sufficient to recover our net book value in such assets, resulting in the need for additional charge-offs. Additional material charge-offs to our investments in OREO could have a material adverse effect on our financial condition and results of operations. In addition, bank regulators periodically review our OREO and may require us to recognize further charge-offs. Significant charge-offs, as required by such regulators, may have a material adverse effect on our financial condition and results of operations.

We may incur losses on our securities portfolio as a result of changes in interest rates.

Factors beyond our control can significantly influence the fair value of securities in our portfolio and can cause potential adverse changes to the fair value of these securities. These factors include, but are not limited to, rating agency actions in respect of the securities, defaults by, or other adverse events affecting, the issuer or with respect to the underlying securities, and changes in market interest rates and continued instability in the capital markets. Any of these factors, among others, could cause other-than-temporary impairments and realized and/or unrealized losses in future periods and declines in other comprehensive income, which could have a material effect on our business, financial condition and results of operations. The process for determining whether impairment of a security is other-than-temporary usually requires complex, subjective judgments about the future financial performance and liquidity of the issuer and any collateral underlying the security to assess the probability of receiving all contractual principal and interest payments on the security. There can be no assurance that the declines in market value will not result in other-than-temporary impairments of these assets, and would lead to accounting charges that could have a material adverse effect on our net income and capital levels.

Changes in interest rates may reduce our net interest income, and may result in higher defaults in a rising rate environment.

Our earnings and cash flows are largely dependent upon our net interest income. Interest rates are highly sensitive to many factors that are beyond our control, including general economic conditions and policies of various governmental and regulatory agencies and, in particular, the Federal Reserve Board. In an attempt to help the overall economy, the Federal Reserve has kept interest rates low through its targeted Fed Funds rate. Beginning in December 2016, the Federal Reserve Board has increased the Fed Funds rate by 100 basis points to a range of 1.25% to 1.50% in December 2017 and indicated a likelihood for a further increase of 25 basis points or more during 2018 subject to economic conditions. As the Federal Reserve increases the Fed Funds rate, overall interest rates will likely rise, which may negatively impact both the housing markets by reducing refinancing activity and new home purchases and the U.S. economic recovery.

We principally manage interest rate risk by managing our volume and mix of our earning assets and funding liabilities. Changes in monetary policy, including changes in interest rates, could influence not only the interest we receive on loans and investments and the amount of interest we pay on deposits and borrowings, but these changes could also affect (i) our ability to originate and/or sell loans and obtain deposits, (ii) the fair value of our financial assets and liabilities, which could negatively impact shareholders’ equity, and our ability to realize gains from the sale of such assets, (iii) our ability to obtain and retain deposits in competition with other available investment alternatives, (iv) the ability of our borrowers to repay adjustable or variable rate loans, and (v) the average duration of our mortgage-backed securities portfolio and other interest-earning assets. If the interest rates paid on deposits and borrowings increase at a faster rate than the interest rates received on loans and other investments, our net interest income, and therefore earnings, could be adversely affected.

Changes in interest rates could also have a negative impact on our results of operations by reducing the ability of borrowers to repay their current loan obligations or by reducing our margins and profitability. Our net interest margin is the difference between the yield we earn on our assets and the interest rate we pay for deposits and our other sources of funding. Changes in interest rates-up or down-could adversely affect our net interest margin and, as a result, our net interest income. Although the yield we earn on our assets and our funding costs tend to move in the same direction in response to changes in interest rates, one can rise or fall faster than the other, causing our net interest margin to expand or contract. Our liabilities tend to be shorter in duration than our assets, so they may adjust faster in response to changes in interest rates. As a result, when interest rates rise, our funding costs may rise faster than the yield we earn on our assets, causing our net interest margin to contract until the yields on interest-earning assets catch up.

Changes in the slope of the “yield curve”, or the spread between short-term and long-term interest rates-could also reduce our net interest margin. Normally, the yield curve is upward sloping, meaning short-term rates are lower than long-term rates. Because our liabilities tend to be shorter in duration than our assets, when the yield curve flattens or even inverts, we could experience pressure on our net interest margin as our cost of funds increases relative to the yield we can earn on our assets. Also, interest rate decreases can lead to increased prepayments of loans and mortgage-backed securities as borrowers refinance their loans to reduce borrowing costs. Under these circumstances, we are subject to reinvestment risk as we may have to redeploy such repayment proceeds into lower yielding investments, which would likely hurt our income.

A sustained increase in market interest rates could adversely affect our earnings. A substantial amount of our loans have adjustable interest rates. As a result, these loans may experience a higher rate of default in a rising interest rate environment. Further, a significant portion of our adjustable rate loans have interest rate floors below which the loan's contractual interest rate may not adjust. Approximately $140.6 million or 34.7 % of our loan portfolio was comprised of adjustable or floating-rate loans at

December 31, 2017 , and approximately $92.9 million, or 66.1%, of those loans contained interest rate floors, below which the loans' contractual interest rate may not adjust. At December 31, 2017 , the weighted average floor interest rate of these loans was 4.33%. At that date, approximately $36.9 million, or 39.7%, of these loans were at their floor interest rate. The inability of our loans to adjust downward can contribute to increased income in periods of declining interest rates, although this result is subject to the risks that borrowers may refinance these loans during periods of declining interest rates. Also, when loans are at their floors, there is a further risk that our interest income may not increase as rapidly as our cost of funds during periods of increasing interest rates which could have a material adverse effect on our results of operations.

Although management believes it has implemented effective asset and liability management strategies to reduce the potential effects of changes in interest rates on our results of operations, any substantial, unexpected or prolonged change in market interest rates could have a material adverse effect on our financial condition and results of operations. Also, our interest rate risk modeling techniques and assumptions likely may not fully predict or capture the impact of actual interest rate changes on our balance sheet. See Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations - Asset and Liability Management and Market Risk” included in the Annual Report.

Liquidity risk could impair our ability to fund operations and jeopardize our financial condition, growth and prospects.

Liquidity is essential to our business. An inability to raise funds through deposits, borrowings, the sale of loans or other sources could have a substantial negative effect on our liquidity. Our primary sources of liquidity are increases in deposits, advances, as needed, from the FHLB, borrowings, as needed, from the Federal Reserve Bank of Richmond ("FRB") and other borrowings to fund our operations. Although we have historically been able to replace maturing deposits and advances if desired, we may not be able to replace such funds in the future if, among other things, our financial condition, the financial condition of the FHLB or FRB, or market conditions change. Factors that could detrimentally impact our access to liquidity sources include a decrease in the level of our business activity as a result of a downturn in the South Carolina or Georgia markets where our loans are concentrated, negative operating results, or adverse regulatory action against us. Our ability to borrow could also be impaired by factors that are not specific to us, such as a disruption in the financial markets or negative views and expectations about the prospects for the financial services industry in light of the recent turmoil faced by banking organizations or deterioration in credit markets. Deposit flows, calls of investment securities and wholesale borrowings, and the prepayment of loans and mortgage-related securities are also strongly influenced by such external factors as the direction of interest rates, whether actual or perceived, and competition for deposits and loans in the markets we serve. Furthermore, changes to the FHLB's underwriting guidelines for wholesale borrowings or lending policies may limit or restrict our ability to borrow, and could therefore have a significant adverse impact on our liquidity. In addition, the need to replace funds in the event of large-scale withdrawals of brokered deposits could require us to pay significantly higher interest rates on retail deposits or other wholesale funding sources, which would have an adverse impact on our net interest income and net income. A decline in available funding could adversely impact our ability to originate loans, invest in securities, meet our expenses, or to fulfill such obligations as repaying our borrowings or meeting deposit withdrawal demands.

Our financial flexibility will be severely constrained if we are unable to maintain our access to funding or if adequate financing is not available to accommodate future growth at acceptable interest rates. Although we consider our sources of funds adequate for our liquidity needs, we may seek additional debt in the future to achieve our long-term business objectives. Additional borrowings, if sought, may not be available to us or, if available, may not be available on reasonable terms. If additional financing sources are unavailable, or are not available on reasonable terms, our financial condition, results of operations, growth and future prospects could be materially adversely affected. Finally, if we are required to rely more heavily on more expensive funding sources to support future growth, our revenues may not increase proportionately to cover our costs. Additionally, collateralized public funds are bank deposits of state and local municipalities. These deposits are required to be secured by certain investment grade securities to ensure repayment, which on the one hand, tends to reduce our contingent liquidity risk by making these funds somewhat less credit sensitive, but on the other hand, reduces standby liquidity by restricting the potential liquidity of the pledged collateral. Although these have historically been a relatively stable source of funds for us, availability depends on the individual municipality's fiscal policies and cash flow needs. At December 31, 2017 , $38.7 million of our deposits were public funds.

We operate in a highly regulated environment and may be adversely affected by changes in federal and state laws and regulations that are expected to increase our costs of operations.

As a state-chartered, federally insured commercial bank, the Bank is currently subject to extensive examination, supervision and comprehensive regulation by the FDIC and the State Board. The Company, as a bank holding company, is subject to examination, supervision and regulation by the Federal Reserve. These regulatory authorities have extensive discretion in connection with their supervisory and enforcement activities, including the ability to impose restrictions on an institution's operations, reclassify assets, determine the adequacy of an institution's allowance for loan losses and determine the level of deposit insurance premiums assessed.

These regulations, along with the currently existing tax, accounting, securities, insurance, and monetary laws, regulations, rules, standards, policies, and interpretations control the methods by which financial institutions conduct business, implement strategic initiatives and tax compliance, and govern financial reporting and disclosures. These laws, regulations, rules, standards, policies, and interpretations are constantly evolving and may change significantly over time. Any new regulations or legislation, change in existing regulations or oversight, whether a change in regulatory policy or a change in a regulator’s interpretation of a law or regulation, could have a material impact on our operations, increase our costs of regulatory compliance and of doing business and or otherwise adversely affect us and our profitability. Further, changes in accounting standards can be both difficult to predict and involve judgment and discretion in their interpretation by us and our independent accounting firms. These changes could materially impact, potentially even retroactively, how we report our financial condition and results of our operations as could our interpretation of those changes.

As discussed under “Business - Regulation” in Item 1 of this Form 10-K, the Dodd-Frank Act has significantly changed the bank regulatory structure and will affect the lending, deposit, investment, trading and operating activities of financial institutions and their holding companies. The Dodd-Frank Act requires various federal agencies to adopt and implement a broad range of new rules and regulations, and to prepare numerous studies and reports for Congress. The federal agencies have significant discretion in drafting and implementing rules and regulations, and consequently, many of the details and much of the impact of the Dodd-Frank Act may not be known for many months or years. It is difficult at this time to predict when or how any new standards will ultimately be applied to us or what specific impact the Dodd-Frank Act and the yet to be written rules and regulations for implementation will have on community banks. However, it is expected that at a minimum they will increase our operating and compliance costs and could increase our non-interest expense. Additional changes in our regulation and oversight, whether in the form of new laws, rules or regulations, could likewise make compliance more difficult or expensive or otherwise materially adversely affect our business, financial condition or prospects.

A new accounting standard will likely require us to increase our allowance for loan losses and may have a material adverse effect on our financial condition and results of operations.

The FASB has adopted a new accounting standard that will be effective for the Company and the Bank after December 15, 2019. This standard, referred to as Current Expected Credit Loss, or CECL, will require financial institutions to determine periodic estimates of lifetime expected credit losses on loans, and recognize the expected credit losses as allowances for loan losses. This will change the current method of providing allowances for loan losses that are probable, which would likely require us to increase our allowance for loan losses, and to greatly increase the types of data we would need to collect and review to determine the appropriate level of the allowance for loan losses. Any increase in our allowance for loan losses or expenses incurred to determine the appropriate level of the allowance for loan losses may have a material adverse effect on our financial condition and results of operations.

Non-compliance with the USA PATRIOT Act, Bank Secrecy Act, or other laws and regulations could result in fines or sanctions.

The USA PATRIOT and Bank Secrecy Acts require financial institutions to develop programs to prevent financial institutions from being used for money laundering and terrorist activities. If such activities are detected, financial institutions are obligated to file suspicious activity reports with the U.S. Treasury’s Office of Financial Crimes Enforcement Network. These rules require financial institutions to establish procedures for identifying and verifying the identity of customers seeking to open new financial accounts. In recent years, several banking institutions have received large fines for non-compliance with these laws and regulations. While we have developed policies and procedures designed to assist in compliance with these laws and regulations, no assurance can be given that these policies and procedures will be effective in preventing violations of these laws and regulations. If our policies and procedures were deemed deficient, we would be subject to liability, including fines and regulatory actions, which may include restrictions on our ability to pay dividends and the denial of regulatory approvals to proceed with certain aspects of our business plan, including acquisitions.

Failure to maintain and implement adequate programs to combat money laundering and terrorist financing could also have serious reputational consequences for us. Any of these results could have a material adverse effect on our business, financial condition, results of operations and growth prospects.

Our growth or future losses may require us to raise additional capital in the future, but that capital may not be available when it is needed, or the cost of that capital may be very high.

We are required by federal regulatory authorities to maintain adequate levels of capital to support our operations. We anticipate that our capital resources will satisfy our capital requirements for the foreseeable future. Nonetheless, we may at some point need to raise additional capital to support continued growth or be required by our regulators to increase our capital resources. Our ability to raise additional capital, if needed, will depend on conditions in the capital markets at that time, which are outside our control, and on our financial condition and performance. Accordingly, we may not be able to raise additional capital, if needed,

on terms that are acceptable to us. If we cannot raise additional capital when needed, our operations could be materially impaired and our financial condition and liquidity could be materially and adversely affected. In addition, if we are unable to raise additional capital when required by our banking regulators, we may be subject to additional adverse regulatory action.

An increase in interest rates, change in the programs offered by governmental sponsored entities ("GSE"), or our ability to qualify for such programs may reduce our mortgage revenues, which would negatively impact our non-interest income.

Our mortgage banking operations provide a portion of our non-interest income. We generate mortgage revenues primarily from gains on the sale of single-family mortgage loans underwritten pursuant to programs currently offered by Freddie Mac and other non-GSE investors. These entities account for a substantial portion of the secondary market in residential mortgage loans. Any future changes in these programs, our eligibility to participate in such programs, the criteria for loans to be accepted or laws that significantly affect the activity of such entities could, in turn, materially adversely affect the success of our mortgage banking program and, consequently, our results of operations.

Mortgage loan production levels are sensitive to changes in economic conditions and can suffer from decreased economic activity, a slowdown in the housing market or higher interest rates. Generally, any sustained period of decreased economic activity or higher interest rates could adversely affect mortgage originations and, consequently, adversely affect income from mortgage lending activities.

In the past several years, as a result of government actions and other economic factors related to the economic downturn, interest rates have been at historically low levels. In December 2017, the Federal Reserve slightly increased the targeted Fed Funds rate by 25 basis points for the third time within a year and intends further increases during 2018 subject to economic conditions. As the Federal Reserve increases the Fed Funds rate, refinancing activity typically declines and new home purchases may be negatively impacted. To the extent that market interest rates increase in the future, our ability to originate mortgage loans held for sale may decrease, resulting in fewer loans that are available to be sold to investors. This would adversely affect our ability to generate mortgage revenues, and consequently noninterest income. Because interest rates depend on factors outside of our control, we cannot eliminate the interest rate risk associated with our mortgage operations.

Our results of operations will also be affected by the amount of non-interest expense associated with mortgage banking activities, such as salaries and employee benefits, occupancy, equipment and data processing expense and other operating costs. If we cannot generate a sufficient volume of loans for sale, our results of operations may be adversely affected. In addition, during periods of reduced loan demand, our results of operations may be adversely affected to the extent that we are unable to reduce expenses commensurate with the decline in loan originations. Finally, deteriorating economic conditions may also increase the potential for home buyers to default on their mortgages. In certain of these cases where we have originated loans and sold them to investors, we may be required to repurchase loans or provide a financial settlement to investors if it is proven that the borrower failed to provide full and accurate information on or related to their loan application or for which appraisals have not been acceptable or when the loan was not underwritten in accordance with the loan program specified by the loan investor. If repurchase and indemnity demands increase on loans that we sell from our portfolios, our liquidity, results of operations and financial condition could be adversely affected.

We are subject to certain risks in connection with our use of technology.

Our security measures may not be sufficient to mitigate the risk of a cyber attack. Communications and information systems are essential to the conduct of our business, as we use such systems to manage our customer relationships, our general ledger and virtually all other aspects of our business. Our operations rely on the secure processing, storage, and transmission of confidential and other information in our computer systems and networks. Although we take protective measures and endeavor to modify them as circumstances warrant, the security of our computer systems, software, and networks may be vulnerable to breaches, unauthorized access, misuse, computer viruses, or other malicious code and cyber attacks that could have a security impact. If one or more of these events occur, this could jeopardize our or our customers' confidential and other information processed and stored in, and transmitted through, our computer systems and networks, or otherwise cause interruptions or malfunctions in our operations or the operations of our customers or counterparties. We may be required to expend significant additional resources to modify our protective measures or to investigate and remediate vulnerabilities or other exposures, and we may be subject to litigation and financial losses that are either not insured against or not fully covered through any insurance maintained by us. We could also suffer significant reputational damage.

Security breaches in our internet banking activities could further expose us to possible liability and damage our reputation. Any compromise of our security also could deter customers from using our internet banking services that involve the transmission of confidential information. We rely on standard internet security systems to provide the security and authentication necessary to effect secure transmission of data. These precautions may not protect our systems from compromises or breaches of our security measures, which could result in significant legal liability and significant damage to our reputation and our business.

Our security measures may not protect us from systems failures or interruptions. While we have established policies and procedures to prevent or limit the impact of systems failures and interruptions, there can be no assurance that such events will not occur or that they will be adequately addressed if they do. In addition, we outsource certain aspects of our data processing and other operational functions to certain third-party providers. If our third-party providers encounter difficulties, or if we have difficulty in communicating with them, our ability to adequately process and account for transactions could be affected, and our business operations could be adversely impacted. Threats to information security also exist in the processing of customer information through various other vendors and their personnel.

The occurrence of any failures or interruptions may require us to identify alternative sources of such services, and we cannot assure you that we could negotiate terms that are as favorable to us, or could obtain services with similar functionality as found in our existing systems without the need to expend substantial resources, if at all. Further, the occurrence of any systems failure or interruption could damage our reputation and result in a loss of customers and business, could subject us to additional regulatory scrutiny, or could expose us to legal liability. Any of these occurrences could have a material adverse effect on our financial condition and results of operations.

We rely on dividends from Security Federal Bank for substantially all of our revenue.

Security Federal Corporation is a separate and distinct legal entity from our principal subsidiary, Security Federal Bank, and receives substantially all of its revenue in the form of dividends from that subsidiary. Accordingly, Security Federal Corporation is, and will be, dependent upon dividends from Security Federal Bank to pay dividends on Security Federal Corporation's capital stock and interest and principal on its debt. Various federal and/or state laws and regulations limit the amount of dividends that Security Federal Bank may pay to Security Federal Corporation. In the event Security Federal Bank is unable to pay dividends, Security Federal Corporation may not be able to service its debt, pay obligations or pay dividends on its capital stock. The inability of Security Federal Corporation to receive dividends from Security Federal Bank could have a material adverse effect on Security Federal Corporation’s business, financial condition and results of operations.

Our exposure to operational risks may adversely affect us.

Similar to other financial institutions, we are exposed to many types of operational risk, including reputational risk, legal and compliance risk, the risk of fraud or theft by employees or outsiders, the risk that sensitive customer or Company data is compromised, unauthorized transactions by employees or operational errors, including clerical or record-keeping errors. Nationally, reported incidents of fraud and other financial crimes have increased. We have also experienced losses due to apparent fraud and other financial crimes. While we have policies and procedures designed to prevent such losses, there can be no assurance that such losses will not occur.

We are dependent on key personnel and the loss of one or more of those key personnel may materially and adversely affect our prospects.

Competition for qualified employees and personnel in the banking industry is intense and there are a limited number of qualified persons with knowledge of, and experience in, the community banking industry where Security Federal Bank conducts its business. The process of recruiting personnel with the combination of skills and attributes required to carry out our strategies is often lengthy. Our success depends to a significant degree upon our ability to attract and retain qualified management, loan origination, finance, administrative, marketing and technical personnel and upon the continued contributions of our management and personnel. In particular, our success has been and continues to be highly dependent upon the abilities of key executives, including our Chief Executive Officer, J. Chris Verenes, and certain other employees. In addition, our success has been and continues to be highly dependent upon the services of our directors, many of whom are at or nearing retirement age, and we may not be able to identify and attract suitable candidates to replace such directors.

Item 9A. Controls and Procedures

(a) Evaluation of Disclosure Controls and Procedures : An evaluation of the Company's disclosure controls and procedures (as defined in Section 13a-15(e) of the Securities Exchange Act of 1934 (the "Act")) was carried out under the supervision and with the participation of the Company's Chief Executive Officer, Chief Financial Officer and several other members of the Company's senior management as of the end of the period covered by this report. The Company's Chief Executive Officer and Chief Financial Officer concluded that the Company's disclosure controls and procedures as currently in effect are effective in ensuring that the information required to be disclosed by the Company in the reports it files or submits under the Act is (i) accumulated and communicated to the Company's management (including the Chief Executive Officer and Chief Financial Officer) in a timely manner, and (ii) recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms.

(b) Report of Management on Internal Control over Financial Reporting : The management of the Company is responsible for establishing and maintaining adequate internal control over financial reporting. The internal control process has been designed under our supervision to provide reasonable assurance regarding the reliability of financial reporting and the preparation of the Company's financial statements for external reporting purposes in accordance with accounting principles generally accepted in the United States of America.

Management conducted an assessment of the effectiveness of the Company's internal control over financial reporting as of December 31, 2017 , utilizing the framework established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on this assessment, management has determined that the Company's internal control over financial reporting as of December 31, 2017 is effective.

Our internal control over financial reporting includes policies and procedures that pertain to the maintenance of records that accurately and fairly reflect, in reasonable detail, transactions and dispositions of assets; and provide reasonable assurances that: (1) transactions are recorded as necessary to permit preparation of financial statements in accordance with accounting principles generally accepted in the United States; (2) receipts and expenditures are being made only in accordance with authorizations of management and the directors of the Company; and (3) unauthorized acquisition, use, or disposition of the Company's assets that could have a material effect on the Company's financial statements are prevented or timely detected.

All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation. 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.

This annual report does not include an attestation report of the Company's independent registered public accounting firm regarding internal control over financial reporting. Management's report was not subject to attestation by the Company's independent registered public accounting firm pursuant to temporary rules of the Securities and Exchange Commission that permit the Company to provide only management's report in this annual report.

(c) Changes in Internal Controls : There have been no changes in the Company's internal control over financial reporting during the quarter ended December 31, 2017 that have materially affected, or are reasonably likely to materially affect, the Company's internal control over financial reporting.

Item 9B. Other Information
