Organization, Consolidation, Basis of Presentation, Business Description and Accounting Policies [Text Block]	Note 1: Nature of Operations and Summary of Significant Accounting Policies Nature of Operations Hamilton Bancorp, Inc. (the “Company”) was incorporated on June 7, 2012 October 10, 2012, the Bank converted from a mutual savings bank to a stock savings bank and became the wholly owned subsidiary of the Company. In connection with the conversion, the Company sold 3,703,000 $10.00 $35,580,000, $1,450,000. 8.0% 296,240 October 12, 2012. In accordance with the Office of the Comptroller of the Currency (the “OCC”) regulations, upon the completion of the conversion, the Bank restricted retained earnings by establishing a liquidation account. The liquidation account will be maintained for the benefit of eligible account holders who continue to maintain their accounts at the Bank after conversion. The liquidation account will be reduced annually to the extent that eligible account holders have reduced their qualifying deposits. Subsequent increases will not ’s interest in the liquidation account. In the event of a complete liquidation of the Bank, and only in such event, each account holder will be entitled to receive a distribution from the liquidation account in an amount proportionate to the adjusted qualifying account balances then held.

The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial reporting and with instructions for Form 10 –Q and Regulation S–X as promulgated by the Securities and Exchange Commission (the “SEC”). Accordingly, certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. In the opinion of management, the preceding unaudited consolidated financial statements contain all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation of the financial condition and results of operations for the periods presented. We derived the balances as of March 31, 2017 three six September 30, 2017 not may March 31, 2018, 10 March 31, 2017. Certain amounts from prior period financial statements have been reclassified to conform to the current period’s presentation. 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 . The accompanying consolidated financial statements include the accounts of the parent company and its wholly owned subsidiary, Hamilton Bank. All significant intercompany balances and transactions have been eliminated in consolidation. Use of Estimates. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and the accompanying notes. Actual results could differ significantly from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, deferred income tax valuation allowances, the fair value of investment securities and other than temporary impairment of investment securities. Investment Securities. Management determines the appropriate classification of investment securities at the time of purchase. Securities that may September 30, 2017 March 31, 2017 Investment sec urities 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 Receivable. The Bank makes mortgage, commercial, and consumer loans to customers. A substantial portion of the loan portfolio is represented by mortgage loans throughout the Baltimore metropolitan area. The ability of the Bank’s debtors to repay their loans is dependent upon the real estate and general economic conditions in this area. 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 ’s judgment, future payments are reasonably assured. 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. Accounting for Certain Loans or Debt Securities Acquired in a Transfer . May 13, 2016 ( 3 September 11, 2015 no not Accounting Standards Codification (“ASC”) Topic 310 30, Loans and Debt Securities Acquired with Deteriorated Credit Quality The Company considered expected prepayments and estimated the total expected cash flows, which included undiscounted expected principal and interest. The excess of that amount over the fair value of the loan is referred to as accretable yield. Accretable yield is recognized as interest income on a constant yield basis over the expected life of the loan. The excess of the contractual cash flows over expected cash flows is referred to as nonaccretable difference and is not first ASC Topic 310 20, Nonrefundable Fees and Other Costs not 310 20, Allowance for Loan Losses. The allowance for loan losses represents an amount which, in management’s judgment, will be adequate to absorb probable future losses on existing loans. The allowance for loan losses is established, as loan losses are estimated to have occurred, through a provision for loan losses charged to earnings. Loan losses are charged against the allowance when management believes the uncollectability of a loan balance is confirmed. Recoveries on previously charged-off loans are credited to the 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 36 48 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. Management modified the analysis during the quarter ended September 30, 2016 not September 30, 2016, Derivative Financial Instruments and Hedging Activities . Derivatives are initially recognized at fair value on the date the derivative contract is entered into and subsequently re-measured at their fair value. The accounting for changes in the fair value of a derivative depends on the intended use of the derivative and the resulting designation. The Company documents at the inception of the transaction the relationship between hedging instruments and hedged items, as well as its risk management objective and strategy for undertaking various hedge transactions. 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. Stock Based Compensation. Compensation cost is recognized for stock options and restricted stock awards issued to employees and directors, based on the fair value of these awards at the date of grant. A Black-Scholes model is utilized to estimate the fair value of stock options, while the market price of the Company’s common stock at the date of grant is used for restricted stock awards. Compensation cost is recognized over the required service period, generally defined as the vesting period. For awards with graded vesting, compensation cost is recognized on a straight-line basis over the requisite service period for the entire award.

To achieve this objective, the guidance in this update replaces the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to estimate credit losses. The measurement of expected credit losses is based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. An entity must use judgment in determining the relevant information and estimation methods that are appropriate in its circumstances. The guidance in this update is effective for fiscal years beginning after December 15, 2019, December 15, 2018. .

Construction loan repayments are generally dependent on the related properties or the financial condition of its borrower or guarantor. Accordingly, repayment of such loans can be more susceptible to adverse conditions in the real estate market and the regional economy.

In calculating the allowance for loan losses, individual TDRs are evaluated for impairment. 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 overall 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 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 ’s results of operations.

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.

Accounting Policies [Abstract]
Consolidation, Policy [Policy Text Block]	Principles of Consolidation . The accompanying consolidated financial statements include the accounts of the parent company and its wholly owned subsidiary, Hamilton Bank. All significant intercompany balances and transactions have been eliminated in consolidation.
Use of Estimates, Policy [Policy Text Block]	Use of Estimates. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and the accompanying notes. Actual results could differ significantly from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, deferred income tax valuation allowances, the fair value of investment securities and other than temporary impairment of investment securities.
Marketable Securities, Policy [Policy Text Block]	Investment Securities. Management determines the appropriate classification of investment securities at the time of purchase. Securities that may September 30, 2017 March 31, 2017 Investment sec urities 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.
Finance, Loans and Leases Receivable, Policy [Policy Text Block]	Loans Receivable. The Bank makes mortgage, commercial, and consumer loans to customers. A substantial portion of the loan portfolio is represented by mortgage loans throughout the Baltimore metropolitan area. The ability of the Bank’s debtors to repay their loans is dependent upon the real estate and general economic conditions in this area. 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 ’s judgment, future payments are reasonably assured. 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.
Certain Loans and Debt Securities Acquired in Transfer, Recognizing Interest Income on Impaired Loans, Policy [Policy Text Block]	Accounting for Certain Loans or Debt Securities Acquired in a Transfer . May 13, 2016 ( 3 September 11, 2015 no not Accounting Standards Codification (“ASC”) Topic 310 30, Loans and Debt Securities Acquired with Deteriorated Credit Quality The Company considered expected prepayments and estimated the total expected cash flows, which included undiscounted expected principal and interest. The excess of that amount over the fair value of the loan is referred to as accretable yield. Accretable yield is recognized as interest income on a constant yield basis over the expected life of the loan. The excess of the contractual cash flows over expected cash flows is referred to as nonaccretable difference and is not first ASC Topic 310 20, Nonrefundable Fees and Other Costs not 310 20,
Loans and Leases Receivable, Allowance for Loan Losses Policy [Policy Text Block]	Allowance for Loan Losses. The allowance for loan losses represents an amount which, in management’s judgment, will be adequate to absorb probable future losses on existing loans. The allowance for loan losses is established, as loan losses are estimated to have occurred, through a provision for loan losses charged to earnings. Loan losses are charged against the allowance when management believes the uncollectability of a loan balance is confirmed. Recoveries on previously charged-off loans are credited to the 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 36 48 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. Management modified the analysis during the quarter ended September 30, 2016 not September 30, 2016,
Derivatives, Policy [Policy Text Block]	Derivative Financial Instruments and Hedging Activities . Derivatives are initially recognized at fair value on the date the derivative contract is entered into and subsequently re-measured at their fair value. The accounting for changes in the fair value of a derivative depends on the intended use of the derivative and the resulting designation. The Company documents at the inception of the transaction the relationship between hedging instruments and hedged items, as well as its risk management objective and strategy for undertaking various hedge transactions. 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.
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	Stock Based Compensation. Compensation cost is recognized for stock options and restricted stock awards issued to employees and directors, based on the fair value of these awards at the date of grant. A Black-Scholes model is utilized to estimate the fair value of stock options, while the market price of the Company’s common stock at the date of grant is used for restricted stock awards. Compensation cost is recognized over the required service period, generally defined as the vesting period. For awards with graded vesting, compensation cost is recognized on a straight-line basis over the requisite service period for the entire award.

[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.

[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.
