Gains on sales of securities are determined on the specific identification method. Gross gains of $0 $51,030 March 31, 2017 March 31, 2016, $0 $18,881 March 31, 2017 March 31, 2016, The Company evaluates all securities quarterly to determine if any unrealized losses are deemed to be other than temporary. Certain investment securities are valued at less than their historical cost. These declines are primarily the result of the rate for these investments yielding less than current market rates, or declines in stock prices of equity securities. Based on evaluation of available evidence, management believes the declines in fair value for these securities are temporary. It is management’s intent to hold the debt securities to maturity or until recovery of the unrealized loss. Should the impairment of any of these debt securities become other than temporary, the cost basis of the investment will be reduced and the resulting loss recognized in net income in the period the other-than-temporary impairment is identified, to the extent the loss is related to credit issues, and to other comprehensive income to the extent the decline on debt securities is related to other factors and the Company does not intend to sell the security prior to recovery of the unrealized loss. Certain other investments in debt and equity securities are reported in the financial statements at an amount less than their historical cost.

Loan losses are charged against the allowance when management believes the uncollectability of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. The allowance for loan losses is evaluated on a regular basis by management and is based upon management’s periodic review of the collectability of the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may The allowance consists of allocated and general components. The allocated component relates to loans that are classified as impaired. For those loans that are classified as impaired, an allowance is established when the discounted cash flows or collateral value of the impaired loan is lower than the carrying value of that loan. The general component covers nonclassified loans and is based on historical charge-off experience and expected loss given default derived from the Bank’s internal risk rating process. Other adjustments may A loan is considered impaired when, based on current information and events, it is probable that the Bank will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record and the amount of the shortfall in relation to the principal and interest owed. Impairment is measured on a loan-by-loan basis by either the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price or the fair value of the collateral if the loan is collateral dependent. Groups of loans with similar risk characteristics are collectively evaluated for impairment based on the group’s historical loss experience adjusted for changes in trends, conditions and other relevant factors that affect repayment of the loans.

This information includes, but is not limited to, whether (i) the debtor is currently in payment default on any of its debt; (ii) a payment default is probable in the foreseeable future without the modification; (iii) the debtor has declared or is in the process of declaring bankruptcy and (iv) the debtor’s projected cash flow is sufficient to satisfy the contractual payments due under the original terms of the loan without a modification. The Bank considers all aspects of the modification to loan terms to determine whether or not a concession has been granted to the borrower. Key factors considered by the Bank include the debtor’s ability to access funds at a market rate for debt with similar risk characteristics, the significance of the modification relative to unpaid principal balance or collateral value of the debt, and the significance of a delay in the timing of payments relative to the original contractual terms of the loan. The most common concessions granted by the Bank generally include one The following table presents the carrying balance of TDRs as of March 31, 2017 December 31, 2016: March 31, 2017 December 31, 2016 Real estate - residential mortgage: One to four family units $ 1,386,750 $ 1,564,468 Multi-family - - Real estate - construction 5,361,078 5,446,895 Real estate - commercial 5,736,849 5,736,849 Commercial loans 377,846 401,403 Consumer and other loans - - Total $ 12,862,523 $ 13,149,615 The bank did not three March 31, 2017. $372,321 $329,734 March 31, 2017 December 31, 2016, There were no twelve three March 31, 2017 2016. 90 As part of the on-going monitoring of the credit quality of the Bank’s loan portfolio, management tracks loans by an internal rating system. All loans are assigned an internal credit quality rating based on an analysis of the borrower’s financial condition. The criteria used to assign quality ratings to extensions of credit that exhibit potential problems or well-defined weaknesses are primarily based upon the degree of risk and the likelihood of orderly repayment, and their effect on the Bank’s safety and soundness. The following are the internally assigned ratings: Pass: This rating represents loans that have strong asset quality and liquidity along with a multi-year track record of profitability. Special mention: This rating represents loans that are currently protected but are potentially weak. The credit risk may Substandard: This rating represents loans that show signs of continuing negative financial trends and unprofitability and therefore, is inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any. Doubtful: This rating represents loans that have all the weaknesses of substandard classified loans with the additional characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions and values, highly questionable and improbable. Risk characteristics applicable to each segment of the loan portfolio are described as follows. Real estate-Residential 1 4 1 4 1 4 Real estate-Construction: Construction and land development real estate loans are usually based upon estimates of costs and estimated value of the completed project and include independent appraisal reviews and a financial analysis of the developers and property owners. Sources of repayment of these loans may may Real estate-Commercial: Commercial real estate loans typically involve larger principal amounts, and repayment of these loans is generally dependent on the successful operations of the property securing the loan or the business conducted on the property securing the loan. These loans are viewed primarily as cash flow loans and secondarily may Commercial: The commercial portfolio includes loans to commercial customers for use in financing working capital needs, equipment purchases and expansions. The loans in this category are repaid primarily from the cash flow of a borrower’s principal business operation. Credit risk in these loans is driven by creditworthiness of a borrower and the economic conditions that impact the cash flow stability from business operations. Consumer: The consumer loan portfolio consists of various term and line of credit loans such as automobile loans and loans for other personal purposes. Repayment for these types of loans will come from a borrower’s income sources that are typically independent of the loan purpose. Credit risk is driven by consumer economic factors (such as unemployment and general economic conditions in the Bank’s market area) and the creditworthiness of a borrower.

Loan origination fees net of certain direct origination costs, are deferred and amortized as a level yield adjustment over the respective term of the loan. The accrual of interest on loans is discontinued at the time the loan is 90 All interest accrued but not collected for loans that are placed on nonaccrual or charged off is reversed against interest income. The interest on these loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. |

Foreclosed Assets Held for Sale : Foreclosed assets held for sale are classified within Level 3 Impaired loans (Collateral Dependent) : If the impaired loan is identified as collateral dependent, then the fair value method of measuring the amount of impairment is utilized. This method requires obtaining a current independent appraisal of the collateral and applying a discount factor to the value. Impaired loans that are collateral dependent are classified within Level 3 The following table presents the fair value measurement of assets measured at fair value on a nonrecurring basis and the level within the fair value hierarchy in which the fair value measurements fall at March 31, 2017 December 31, 2016 Impaired loans: Level 1 inputs Level 2 inputs Level 3 inputs Total fair value March 31, 2017 $ - $ - $ 7,985 $ 7,985 December 31, 2016 $ - $ - $ 1,006 $ 1,006 Foreclosed assets held for sale: Level 1 inputs Level 2 inputs Level 3 inputs Total fair value March 31, 2017 $ - $ - $ - $ - December 31, 2016 $ - $ - $ 149 $ 149 There were no transfers between valuation levels for any asset during the three March 31, 2017 2016.

Cash and cash equivalents, interest-bearing deposits and Federal Home Loan Bank stock The carrying amounts reported in the condensed consolidated balance sheets approximate those assets' fair value. Held-to-maturity securities Fair value is based on quoted market prices, if available. If a quoted market price is not available, fair value is estimated using quoted market prices for similar securities. Loans The fair value of loans is estimated by discounting the future cash flows using the market rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities. Loans with similar characteristics were aggregated for purposes of the calculations. The carrying amount of accrued interest approximates its fair value. Deposits Deposits include demand deposits, savings accounts, NOW accounts and certain money market deposits. The carrying amount approximates fair value. The fair value of fixed-maturity certificates of deposit is estimated by discounting the future cash flows using rates currently offered for deposits of similar remaining maturities. Federal Home Loan Bank advances The fair value of advances is estimated by using rates on debt with similar terms and remaining maturities. Subordinated debentures For these variable rate instruments, the carrying amount is a reasonable estimate of fair value. There is currently a limited market for similar debt instruments and the Company has the option to call the subordinated debentures at an amount close to its par value. Interest payable The carrying amount approximates fair value. Commitments to originate loans, letters of credit and lines of credit The fair value of commitments to originate loans is estimated using the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the present credit worthiness of the counterparties. For fixed-rate loan commitments, fair value also considers the difference between current levels of interest rates and the committed rates. The fair value of letters of credit and lines of credit are based on fees currently charged for similar agreements or on the estimated cost to terminate them or otherwise settle the obligations with the counterparties at the reporting date.
