Summary of Significant Accounting Policies The accounting and reporting policies of Hamilton Bancorp, Inc. and Subsidiary (“Hamilton”) conform to accounting principles generally accepted in the United States of America (“U.S. GAAP”) and to general practices in the banking industry. The more significant policies follow: Principles of Consolidation Use of Estimates. Investment Securities. may September 30, 2018 March 31, 2018 Investment securities designated as available for sale are stated at estimated fair value based on quoted market prices. They represent those securities which management may may In estimating other-than-temporary impairment losses, management considers the length of time and the extent to which the fair value has been less than cost, the financial condition and near-term prospects of the issuer, and the intent and ability of the Bank to retain its investment in the issuer for a period of time sufficient to allow for any anticipated recovery in fair value. Loans Held For Sale . Loans Receivable. Loans are reported at their outstanding unpaid principal balance adjusted for the allowance for loan loss, premiums on loans acquired, and/or any deferred fees or costs on originated loans. Interest revenue is accrued on the unpaid principal balance. Loan origination fees and the direct costs of underwriting and closing loans are recognized over the life of the related loan as an adjustment to yield using a method that approximates the interest method. Any differences that arise from prepayment will result in a recalculation of the effective yield. Loans are generally placed on nonaccrual status when they are 90 not Loans are considered impaired when, based on current information, management considers it unlikely that collection of principal and interest payments will be made according to contractual terms. If collection of principal is evaluated as doubtful, all payments are applied to principal. Impaired loans are measured: (i) at the present value of expected cash flows discounted at the loan’s effective interest rate; (ii) at the observable market price; or (iii) at the fair value of the collateral if the loan is collateral dependent. If the measure of the impaired loan is less than the recorded investment in the loan, an impairment is recognized through an allocation of the allowance for loan losses and corresponding provision for loan losses. Generally, identified impairments are charged-off against the allowance for loan losses. Troubled debt restructurings are loans for which Hamilton, for legal or economic reasons related to a debtor’s financial difficulties, has granted a concession to the debtor that it otherwise would not ● Reduction of the stated interest rate; ● Extension of the maturity date or dates at a stated interest rate lower than the current market rate for new debt with similar risk; ● Reduction of the face amount or maturity amount of the debt as stated in the instrument or other agreement; or ● Reduction of accrued interest. Allowance for Loan Losses. The allowance for loan losses is increased by provisions charged to income and reduced by charge-offs, net of recoveries. Management’s periodic evaluation of the adequacy of the allowance is based on the Bank’s past loan loss experience, known and inherent risks in the loan portfolio, adverse situations that may 48 September 30, 2018, 36 48 two 48 48 may not September 30, 2018 $294,000 Management considers a number of factors in estimating the required level of the allowance. These factors include: historical loss experience in the loan portfolios; the levels and trends in past-due and nonaccrual loans; the status of nonaccrual loans and other loans identified as having the potential for further deterioration; credit risk and industry concentrations; trends in loan volume; the effects of any changes in lending policies and procedures or underwriting standards; and a continuing evaluation of the economic environment. As part of the estimation process, management keeps the net charge-off history as a percentage of loans, as it pertains to each loan segment, constant across all risk ratings and alters the qualitative factors either up or down based upon the respective risk rating for each loan segment. Foreclosed Real Estate. Goodwill and Other Intangible Assets. may eight not Derivative Financial Instruments and Hedging Activities . For derivatives qualifying as cash flow hedges, the Company also documents its assessment, both at hedge inception and on an ongoing basis, of whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in fair values or cash flows of hedged items. The effective portion of changes in fair value of derivatives that are designated and qualify as cash flow hedges is recognized in the consolidated statement of comprehensive income (loss). The gain or loss relating to the ineffective portion is recognized immediately in the consolidated statement of operations as a gain or loss. When a hedging instrument expires or is sold, or when a hedge no no For derivative instruments designated as fair-value hedges, the change in fair value of the derivative is recognized in the consolidated statement of operations under the same heading as the change in fair value of the hedged item for the portion attributable to the hedged risk. For accounting purposes, if the derivative is highly effective, the change in fair values relating to the asset or liability and the hedged item will offset one no Gains (losses) on derivatives representing either hedge components excluded from the assessment of effectiveness or hedge ineffectiveness are recognized in earnings.

TDRs are evaluated for impairment based upon either the present value of cash flows or, if collateral dependent, the lower of cost or fair value of the underlying collateral. If it is determined that the cash flows or underlying collateral is less than the carrying amount of the loan, the difference in value will be charged-off through earnings, unless the TDR is performing, in which case a specific reserve may Credit quality indicators As part of the ongoing monitoring of the credit quality of the Bank's loan portfolio, management tracks certain credit quality indicators including trends related to the risk grade of loans, the level of classified loans, net charge offs, nonperforming loans, and the general economic conditions in the Bank's market. The Bank utilizes a risk grading matrix to assign a risk grade to each of its loans. A description of the general characteristics of loans characterized as watch list or classified is as follows: Pass A pass loan is considered of sufficient quality to preclude a special mention or an adverse rating. Pass assets generally are well protected by the current net worth and paying capacity of the obligor or by the value of the asset or underlying collateral. Special Mention A special mention loan has potential weaknesses that deserve management's close attention. If left uncorrected, these potential weaknesses may not not Loans that would primarily fall into this notational category could have been previously classified adversely, but the deficiencies have since been corrected. Management should closely monitor recent payment history of the loan and value of the collateral. Borrowers may may may Substandard A substandard loan is inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any. Substandard loans have a well-defined weakness, or weaknesses, that jeopardize the collection or liquidation of the debt. They are characterized by the distinct possibility that the Bank will sustain some loss if the deficiencies are not Borrowers may Doubtful A doubtful loan has all the weaknesses inherent as a substandard loan with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. A loan classified as doubtful exhibits loss potential. However, there is still sufficient reason to permit the loan to remain on the books. A doubtful classification could reflect the deterioration of the primary source of repayment and serious doubt exists as to the quality of the secondary source of repayment. Doubtful classifications should be used only when a distinct and known possibility of loss exists. When identified, adequate loss should be recorded for the specific assets. The entire asset should not Loss Loans classified as loss are considered uncollectable and of such little value that their continuance as loans is unjustified. A loss classification does not no may The following tables present the September 30, 2018 March 31, 2018, no September 30, 2018 March 31, 2018.

The Bank agrees to pay the other financial institution a fixed interest rate on a notional amount based upon the commercial real estate loan and in return receive a variable interest rate on the same notional amount. This transaction allows the Bank to effectively convert a fixed rate loan to a variable rate. Because the terms of the swap with the other financial institution and the commercial real estate loan offset each other, with the only difference being credit risk associated with the loan, changes in the fair value of the underlying derivative contract and the commercial real estate loan are not not During the second 2016, $3.3 3.99% 10 $3.0 September 30, 2018. Credit risk arises from the possible inability of counterparties to meet the terms of their contracts. The Bank’s exposure is limited to the replacement value of the contract rather than the notional amount, principal, or contract amount. There are provisions in the agreement with the counterparty that allow for certain unsecured credit exposure up to an agreed threshold. Exposures in excess of the agreed threshold are collateralized. In addition, the Bank minimizes credit risk through credit approvals, limits, and monitoring procedures.

Finance, Loans and Leases Receivable, Policy [Policy Text Block]	Loans Receivable. Loans are reported at their outstanding unpaid principal balance adjusted for the allowance for loan loss, premiums on loans acquired, and/or any deferred fees or costs on originated loans. Interest revenue is accrued on the unpaid principal balance. Loan origination fees and the direct costs of underwriting and closing loans are recognized over the life of the related loan as an adjustment to yield using a method that approximates the interest method. Any differences that arise from prepayment will result in a recalculation of the effective yield. Loans are generally placed on nonaccrual status when they are 90 not Loans are considered impaired when, based on current information, management considers it unlikely that collection of principal and interest payments will be made according to contractual terms. If collection of principal is evaluated as doubtful, all payments are applied to principal. Impaired loans are measured: (i) at the present value of expected cash flows discounted at the loan’s effective interest rate; (ii) at the observable market price; or (iii) at the fair value of the collateral if the loan is collateral dependent. If the measure of the impaired loan is less than the recorded investment in the loan, an impairment is recognized through an allocation of the allowance for loan losses and corresponding provision for loan losses. Generally, identified impairments are charged-off against the allowance for loan losses. Troubled debt restructurings are loans for which Hamilton, for legal or economic reasons related to a debtor’s financial difficulties, has granted a concession to the debtor that it otherwise would not ● Reduction of the stated interest rate; ● Extension of the maturity date or dates at a stated interest rate lower than the current market rate for new debt with similar risk; ● Reduction of the face amount or maturity amount of the debt as stated in the instrument or other agreement; or ● Reduction of accrued interest.

[1]	Generally accepted accounting principles require that we record acquired loans at fair value at acquisition, which includes a discount for loans with credit impairment. These purchased credit impaired loans are not performing according to their contractual terms and meet the definition of an impaired loan. Although we do not accrue interest income at the contractual rate on these loans, we do recognize an accretable yield as interest income to the extent such yield is supported by cash flow analysis of the underlying loans.
