Allowance for Credit Losses - Loans Receivable	Allowance for Credit Losses – Loans Receivable The Company applies ASU 2016-13, Financial Instruments - Credit Losses ("ASC 326"), such that the allowance calculation is based on the current expected credit loss (“CECL”) methodology. The Company maintains an allowance for credit losses (“ACL”) for the expected credit losses of the loan portfolio as well as unfunded loan commitments. The amount of ACL is based on ongoing, quarterly assessments by management. The CECL methodology requires an estimate of the credit losses expected over the life of an exposure (or pool of exposures) and replaces the incurred loss methodology’s threshold that delayed the recognition of a credit loss until it was probable that a loss event was incurred. The ACL consists of the allowance for credit losses and the reserve for unfunded commitments. The estimate of expected credit losses under the CECL methodology is based on relevant information about past events, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amounts. Historical loss experience is generally the starting point for estimating expected credit losses. We then consider whether the historical loss experience should be adjusted for asset-specific risk characteristics or current conditions at the reporting date that did not exist over the period that historical experience was based on for each loan type. Finally, we consider forecasts about future economic conditions or changes in collateral values that are reasonable and supportable. Portfolio segment is defined as the level at which the Company develops and documents a systematic methodology to determine its ACL. The Company has designated three loan portfolio segments: loans secured by real estate, commercial and industrial loans, and consumer loans. These loan portfolio segments are further disaggregated into classes, which represent loans of similar type, risk characteristics, and methods for monitoring and assessing credit risk. The loans secured by the real estate portfolio segment are disaggregated into five classes: construction and land, farmland, single-family residential, multi-family, and commercial. The commercial and industrial loan portfolio segment is disaggregated into two classes: commercial and industrial, and SBA guaranty. The risk of loss for the commercial and industrial loan portfolio segment is generally most indicated by the credit risk rating assigned to each borrower. Commercial and industrial loan risk ratings are determined by experienced senior credit officers based on specific facts and circumstances and are subject to periodic review by an independent internal team of credit specialists. The consumer loan portfolio segment is disaggregated into two classes: consumer and automobile. The risk of loss for the consumer loan portfolio segment is generally most indicated by delinquency status and general economic factors. Each of the three loan portfolio segments may also be further segmented based on risk characteristics. For most of our loan portfolio classes, the historical loss experience is determined using the Average Charge-Off Method. This method pools loans into groups (“cohorts”) sharing similar risk characteristics and tracks each cohort’s net charge-offs over the lives of the loans. The Average Charge-Off Method uses historical values by period (20-year look-back) to calculate losses and then applies the historical average to future balances over the life of the account. The historical loss rates for each cohort are then averaged to calculate an overall historical loss rate which is applied to the current loan balance to arrive at the quantitative baseline portion of the allowance for credit losses for the respective loan portfolio class. For certain loan portfolio classes, the Company determined there was not sufficient historical loss information to calculate a meaningful historical loss rate using the average charge-off methodology. For any such loan portfolio class, peer group history contributes to the Company’s weighted average loss history. The peer group data is included in the weighted average loss history that is developed for each loan pool. The Company also considers qualitative adjustments to the historical loss rate for each loan portfolio class. The qualitative adjustments for each loan class consider the conditions over the 20-year look-back period from which historical loss experience was based and are split into two components: 1) asset or class specific risk characteristics or current conditions at the reporting date related to portfolio credit quality, remaining payments, volume and nature, credit culture and management, business environment or other management factors; and 2) reasonable and supportable forecasts of future economic conditions and collateral values. The Company performs a quarterly asset quality review which includes a review of forecasted gross charge-offs and recoveries, nonperforming assets, criticized loans, risk rating migration, delinquencies, etc. The asset quality review is performed by management and the results are used to consider a qualitative overlay to the quantitative baseline. When management deems it to be appropriate, the Company establishes a specific reserve for individually evaluated loans that do not share similar risk characteristics with the loans included in each respective loan pool. These individually evaluated loans are removed from their respective pools and typically represent collateral dependent loans but may also include other non-performing loans or restructured loans to borrowers experiencing financial difficulty. Allowance for Credit Losses – Held-to-Maturity Debt Securities For held-to-maturity (“HTM”) debt securities, the Company is required to utilize a CECL methodology to estimate expected credit losses. The Company does not own any HTM debt securities. Therefore, the Company did not record an allowance for credit losses for these types of securities. Allowance for Credit Losses – Available for Sale Debt Securities The impairment model for available for sale (“AFS”) debt securities differs from the CECL methodology applied for HTM debt securities because AFS debt securities are measured at fair value rather than amortized cost. Although ASC 326 replaced the legacy other-than-temporary impairment (“OTTI”) model with a credit loss model, it retained the fundamental nature of the legacy OTTI model. For AFS debt securities in an unrealized loss position, the Company first assesses whether it intends to sell, or it is more likely than not that it will be required to sell, the security before recovery of its amortized cost basis. If either criterion is met, the security’s amortized cost basis is written down to fair value through income. For AFS debt securities where neither of the criteria are met, the Company evaluates whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, management considers the extent to which fair value is less than amortized cost, any changes to the credit rating of the security by a rating agency, and adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security is compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded for the credit loss, limited to the amount that the fair value is less than the amortized cost basis. Any remaining discount that has not been recorded through an allowance for credit losses is recognized in other comprehensive income. Under the new guidance, an entity may no longer consider the length of time fair value has been less than amortized cost. Changes in the allowance for credit losses are recorded as a provision (or release) for credit losses. Losses are charged against the allowance when management believes the collectability of an AFS security is considered below the amortized cost basis of the security. As of December 31, 2024 and September 30, 2025, the Company determined that the unrealized loss positions in AFS securities were not the result of credit losses, and therefore, an allowance for credit losses was not recorded.
Off-Balance-Sheet Credit Exposures	Off-Balance-Sheet Credit Exposures The only material off-balance-sheet credit exposures are unfunded loan commitments, which had a combined balance of $37.5 million on September 30, 2025. The reserve for unfunded commitments is recognized as a liability (Accrued expenses and other liabilities in the consolidated statements of financial condition), with adjustments to the reserve recognized through provision for credit losses in the consolidated statements of income. The reserve for unfunded commitments represents the expected lifetime credit losses on off-balance sheet obligations such as commitments to extend credit and standby letters of credit. However, a liability is not recognized for commitments that are unconditionally cancellable by the Company. The reserve for unfunded commitments is determined by estimating future draws, including the effects of risk mitigation actions, and applying the expected loss rates on those draws. Loss rates are estimated by utilizing the same loss rates calculated for the allowance for credit losses related to the respective loan portfolio class.
Principles of Consolidation	Principles of Consolidation The consolidated financial statements include the accounts of the Company and its wholly owned subsidiary, The Bank of Glen Burnie. Consolidation resulted in the elimination of all intercompany accounts and transactions.
Cash Flow Presentation	Cash Flow Presentation In the statements of cash flows, cash and cash equivalents include cash on hand, amounts due from banks, Federal Home Loan Bank of Atlanta (“FHLB Atlanta”) overnight deposits, and federal funds sold. Generally, federal funds are sold for one-day periods.
Reclassifications	Reclassifications Certain items in the fiscal year 2024 consolidated financial statements have been reclassified to conform to the fiscal year 2025 classifications. The reclassifications had no effect on previously reported results of operations or retained earnings.
Use of Estimates	Use of Estimates The preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ materially from those estimates. Material estimates that are particularly susceptible to significant change in the near term include the determination of the ACL; the fair value of financial instruments, such as loans and investment securities; benefit plan obligations and expenses; and the valuation of deferred tax assets.

Disclosure of accounting policy for the use of estimates in the preparation of financial statements in conformity with generally accepted accounting principles.
