The accompanying unaudited consolidated financial statements were prepared in accordance with instructions for Form 10-Q and accounting principles generally accepted in the United States of America ("GAAP"); therefore, they do not include all disclosures necessary for a complete presentation of financial condition, results of operations, and cash flows.  Such statements are unaudited but, in the opinion of management, reflect all adjustments, which are of a normal recurring nature and necessary for a fair presentation of results for the selected interim periods.  Users of financial information produced for interim periods are encouraged to refer to the footnotes contained in the audited consolidated financial statements appearing in Security Federal Corporation’s (the “Company”) 2018 Annual Report to Shareholders which was filed as an exhibit to our Annual Report on Form 10-K for the year ended December 31, 2018 (“2018 Form 10-K”) when reviewing interim financial statements. The unaudited consolidated results of operations for the three and sixnine months ended JuneSeptember 30, 2019 are not necessarily indicative of the results that may be expected for the year ending December 31, 2018. The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

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

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

The Company has adopted various accounting policies, which govern the application of accounting principles generally accepted in the United States in the preparation of our financial statements.  Our significant accounting policies are described in the footnotes to the audited consolidated financial statements at December 31, 2018 included in our 2018 Annual Report to Shareholders.  Certain accounting policies involve significant judgments and assumptions by management, which have a material impact on the carrying value of certain assets and liabilities, and, as such, have a greater possibility of producing results that could be materially different than originally reported.  We consider these accounting policies to be critical accounting policies.  The judgments and assumptions we use are based on historical experience and other factors, which we believe to be reasonable under the circumstances.  Because of the nature of the judgments and assumptions we make, actual results could differ from these judgments and estimates which could have a material impact on our carrying values of assets and liabilities and our results of operations.

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

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

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

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

Accounting guidance specifies the computation, presentation and disclosure requirements for earnings per share (“EPS”) for entities with publicly held common stock or potential common stock such as options, warrants, convertible securities or contingent stock agreements if those securities trade in a public market. Basic EPS is computed by dividing net income by the weighted average number of common shares outstanding.  Diluted EPS is similar to the computation of basic EPS except that the denominator is increased to include the number of additional common shares that would have been outstanding if the dilutive common shares had been issued.  The dilutive effect of options outstanding under the Company’s stock option plan is reflected in diluted EPS by application of the treasury stock method. There were no stock options outstanding at Juneeither September 30, 2019. All of the options outstanding at June2019 or September 30, 2018 had an exercise price below the average market price during the six months ended June 30, 2018. Therefore, these options were considered to be dilutive to EPS in that period. Diluted EPS also assumes the convertible debentures were converted into 302,200 and 303,200 shares of common stock at the beginning of both the three and sixnine month periods ended JuneSeptember 30, 2019 and 2018, respectively. The related interest expense recorded during the period is added back to the EPS numerator while the underlying shares are added to the denominator.

Certain officers and directors of the Company participate in incentive and non-qualified stock option plans. Options are granted at exercise prices not less than the fair value of the Company’s common stock on the date of the grant. At JuneSeptember 30, 2019, the Company had no remaining options outstanding and there was no activity during the sixnine months ended JuneSeptember 30, 2019.

The following is a summary of the activity under the Company’s stock option plans for the three and sixnine months ended JuneSeptember 30, 2018:2018.

The amortized cost, gross unrealized gains, gross unrealized losses, and fair values of investment and mortgage-backed securities available for sale at the dates indicated were as follows:

Student Loan Pools are typically 97% guaranteed by the United States government while SBA bonds are 100% backed by the full faith and credit of the United States government. Included in the tables above and below in mortgage-backed securities are Government National Mortgage Association ("GNMA") mortgage-backed securities, which are also backed by the full faith and credit of the United States government.  At JuneSeptember 30, 2019, AFS GNMA mortgage-backed securities had an amortized cost and fair value of $88.4$84.2 million and $89.3$85.1 million, respectively, compared to an amortized cost and fair value of $80.4 million and $80.2 million, respectively, at December 31, 2018.

Also included in mortgage-backed securities in the tables above and below are private label collateralized mortgage obligation ("CMO") securities, which are issued by non-governmental real estate mortgage investment conduits and are not backed by the full faith and credit of the United States government.  At JuneSeptember 30, 2019 the Bank held AFS private label CMO mortgage-backed securities with an amortized cost and fair value of $27.5$25.1 million and $27.8$25.4 million, respectively, compared to an amortized cost and fair value of $29.7 million and $29.5 million, respectively, at December 31, 2018.

The amortized cost and fair value of investment and mortgage-backed securities available for sale at JuneSeptember 30, 2019 are shown below by contractual maturity.  Expected maturities will differ from contractual maturities because borrowers have the right to prepay obligations with or without call or prepayment penalties. Since mortgage-backed securities are not due at a single maturity date, they are disclosed separately, rather than allocated over the maturity groupings set forth in the table below.

At JuneSeptember 30, 2019 the amortized cost and fair value of investment and mortgage-backed securities available for sale pledged as collateral for certain deposit accounts, FHLB advances and other borrowings were $149.0$145.1 million and $150.9$147.5 million, respectively, compared to an amortized cost and fair value of $111.8 million and $111.7 million, respectively, at December 31, 2018.

The following tables show gross unrealized losses and fair value, aggregated by investment category, and length of time that the individual available for sale securities were in a continuous unrealized loss position at the dates indicated.

Securities classified as available for sale are recorded at fair market value.  At JuneSeptember 30, 2019 and December 31, 2018, 62.0%55.1% and 72.4% of the unrealized losses, representing 7371 and 92 individual securities, respectively, consisted of securities in a continuous loss position for 12 months or more. The Company has the ability and intent to hold these securities until such time as the value recovers or the securities mature.  The Company believes, based on industry analyst reports and credit ratings, that the deterioration in value is attributable to changes in market interest rates and is not in the credit quality of the issuer and therefore, these losses are not considered other-than-temporary. The Company reviews its investment securities portfolio at least quarterly and more frequently when economic conditions warrant, assessing whether there is any indication of other-than-temporary impairment (“OTTI”).

Factors considered in the review include estimated future cash flows, length of time and extent to which market value has been less than cost, the financial condition and near term prospects of the issuer, and our intent and ability to retain the security to allow for an anticipated recovery in market value. If the review determines that there is OTTI, then an impairment loss is recognized in earnings equal to the entire difference between the investment’s cost and its fair value at the balance sheet date of the reporting period for which the assessment is made, or the Company may recognize a portion in other comprehensive income. The fair value of investments on which OTTI is recognized then becomes the new cost basis of the investment. There was no OTTI recognized during the sixnine months ended JuneSeptember 30, 2019.

The amortized cost, gross unrealized gains, gross unrealized losses, and fair values of held to maturity securities at the dates indicated below were as follows:

The FHLB, FHLMC and the Federal National Mortgage Association ("FNMA") are government sponsored enterprises ("GSEs") and the securities and bonds issued by GSEs are not backed by the full faith and credit of the United States government.  At JuneSeptember 30, 2019, the Bank held an amortized cost and fair value of $12.5$12.0 million and $12.8$12.4 million, respectively, in GNMA mortgage-backed securities classified as held to maturity, which are included in the table above, compared to an amortized cost and fair value of $13.3 million and $13.1 million, respectively, at December 31, 2018. The Company has not invested in any private label mortgage-backed securities classified as held to maturity.

At JuneSeptember 30, 2019, the amortized cost and fair value of mortgage-backed securities held to maturity that were pledged as collateral for certain deposit accounts, FHLB advances and other borrowings were $18.7$19.6 million and $19.0$20.1 million, respectively, compared to an amortized cost and fair value of $19.8 million and $19.4 million, respectively, at December 31, 2018.
