The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles (“GAAP”) for interim financial information, Rule 10-01 of Regulation S-X and the instructions to Form 10-Q. The financial statements do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments (consisting of normal recurring accruals) necessary to present fairly the financial position, results of operations, changes in shareholders’ equity, and cash flows of the Company for the periods presented.

The accompanying unaudited consolidated financial statements and related notes should be read in conjunction with the Company’s December 31, 2018 Annual Report on Form 10-K. Operating results for the three and nine months ended September 30, 2019 are not necessarily indicative of the results that may be expected for the year ending December 31, 2019 or for any other period.

The preparation of the unaudited consolidated financial statements requires management of the Company to make a number of estimates and assumptions relating to the reported amount of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the period. Significant items subject to such estimates and assumptions include the allowance for loan losses, deferred income taxes and real estate owned. Actual results could differ from those estimates.

Certain prior period amounts have been reclassified to conform to current period presentation. These reclassifications did not result in any changes to previously reported net income. The Company reclassified the Cost of Shares Repurchased line item presented in prior periods to the Additional Paid in Capital line item in the Consolidated Statements of Financial Condition. The Cost of Shares Repurchased column was reclassified to the Additional Paid in Capital line in the Consolidated Statements of Changes in Shareholders’ Equity.

Impact of Recent Accounting Pronouncements

Accounting Standards Codification ("ASC") Topic 606 "Revenue from Contracts with Customers." Authoritative accounting guidance under ASC Topic 606, "Revenue from Contracts with Customers" amended prior guidance to require an entity to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services and to provide clarification on identifying performance obligations and licensing implementation guidance. The Company's revenue is comprised of interest and non-interest revenue. The guidance does not apply to revenue associated with financial instruments, including loans and securities. The Company completed its overall assessment of revenue streams and related contracts affected by the guidance, including asset management fees, deposit related fees, and other non-interest related fees. The Company adopted ASC 606 as of January 1, 2018 with no impact on total shareholders' equity or net income.

Revenue Recognition

The Company recognizes revenue as it is earned and noted no impact to its revenue recognition policies as a result of the adoption of ASC 606. The following is a discussion of revenues within the scope of the new revenue guidance:
●	Debit and credit card interchange fee income - Card processing fees consist of interchange fees from consumer debit and credit card networks and other card related services. Interchange fees are based on purchase volumes and other factors and are recognized as transactions occur.
●	Service charges on deposit accounts - Revenue from service charges on deposit accounts is earned through deposit-related services; as well as overdraft, non-sufficient funds, account management and other deposit-related fees. Revenue is recognized for these services either over time, corresponding with deposit accounts' monthly cycles, or at a point in time for transactional related services and fees.
●	Service charges on loan accounts - Revenue from loan accounts consists primarily of fees earned on prepayment penalties. Revenue is recognized for these services at a point in time for transactional related services and fees.

ASC Topic 842 "Leases." Authoritative accounting guidance under ASC Topic 842, "Leases" amended prior guidance to require lessees to recognize the assets and liabilities arising from all leases on the balance sheet. The authoritative guidance defines a lease as a contract, or part of a contract, that conveys the right to control the use of identified property, plant, or equipment (an identified asset) for a period of time in exchange for consideration. In addition, the qualifications for a sale and leaseback transaction have been amended. The authoritative guidance also requires qualitative and quantitative disclosures by lessees and lessors to meet the objective of enabling users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases. The Company used a prospective approach. The Company adopted ASC 842 as of January 1, 2019 with no impact on statement of income. See the impact on the financial condition discussed in Note 16.

ASC Topic 326 "Financial Instruments - Credit Losses." Authoritative accounting guidance under ASC Topic 326, "Financial Instruments - Credit Losses" amended 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 for credit loss estimates. 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. The authoritative guidance also requires a financial asset (or a group of financial assets) measured at amortized cost basis to be presented at the net amount expected to be collected (net of the allowance for credit losses). In addition, the credit losses relating to available-for-sale debt securities should be recorded through an allowance for credit losses rather than a write-down. The authoritative guidance will be effective for reporting periods after January 1, 2020. The Company has input the available historical Company data to build an internal model and is reviewing the assumptions to support the calculation. Management is reviewing and communicating the changes to the accounting standard with the appropriate departments. The Company is in process of completing a CECL calculation.

ASC Topic 310 "Receivables - Nonrefundable Fees and Other Costs." Authoritative accounting guidance under ASC Topic 310, "Receivables - Nonrefundable Fees and Other Costs" amends prior guidance by shortening the amortization period for certain callable debt securities held at a premium requiring the premium to be amortized to the earliest call date. The Company adopted ASC 310 as of January 1, 2019 with no material impact on the Company's statements of operations or financial condition.
