Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Presentation Colony Bankcorp, Inc. (the “Company”) is a bank holding company located in Fitzgerald, Georgia. The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary, Colony Bank, Fitzgerald, Georgia (the “Bank”). The “Company” or “our,” as used herein, includes Colony Bank, except where the content requires otherwise. In July 2019, a new subsidiary of the Company was incorporated under the name Colony Risk Management, Inc. Colony Risk Management, Inc. is a subsidiary of the Company and is located in Las Vegas, Nevada. It is a captive insurance subsidiary which insures various liability and property damage policies for the Company and its related subsidiaries. Colony Risk Management is regulated by the State of Nevada Division of Insurance. All adjustments consisting of normal recurring accruals which are, in the opinion of management, necessary for fair presentation of the interim consolidated financial statements, have been included and fairly and accurately present the financial position, results of operations and cash flows of the Company. All significant intercompany accounts have been eliminated in consolidation. The accounting and reporting policies of the Company conform to generally accepted accounting principles and practices utilized in the commercial banking industry for interim financial information and Regulation S-X. Accordingly, the accompanying unaudited interim consolidated financial statements do not include all of the information or notes required for complete financial statements. The results of operations for the three months ended March 31, 2021 are not necessarily indicative of the results which may be expected for the year ending December 31, 2021. These statements should be read in conjunction with the consolidated financial statements and notes thereto in the Company's Annual Report on Form 10-K for the year ended December 31, 2020 (“2020 10-K”). Nature of Operations The Bank provides a full range of retail, commercial and mortgage banking services for consumers and small- to medium-size businesses located primarily in central, south and coastal Georgia. The Bank is headquartered in Fitzgerald, Georgia with banking and mortgage offices in Albany, Ashburn, Athens, Broxton, Centerville, Columbus, Cordele, Douglas, Eastman, Fitzgerald, LaGrange, Leesburg, Macon, Moultrie, Quitman, Rochelle, Savannah, Soperton, Sylvester, Statesboro, Tifton, Valdosta and Warner Robins. Lending and investing activities are funded primarily by deposits gathered through its retail banking office network. Use of Estimates In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the balance sheet date and revenues and expenses for the period. 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, the valuation of real estate acquired in connection with foreclosures or in satisfaction of loans and fair value of assets acquired and liabilities assumed in a business combination, including goodwill impairment. Reclassifications In certain instances, amounts reported in prior years’ consolidated financial statements have been reclassified to conform to statement presentations selected for 2021. Such reclassifications have not materially affected previously reported stockholders’ equity or net income. Concentrations of Credit Risk Concentrations of credit risk can exist in relation to individual borrowers or groups of borrowers, certain types of collateral, certain types of industries, or certain geographic regions. The Company has a concentration in real estate loans as well as a geographic concentration that could pose an adverse credit risk. At March 31, 2021, approximately 78% of the Company’s loan portfolio was concentrated in loans secured by real estate. A substantial portion of borrowers’ ability to honor their contractual obligations is dependent upon the viability of the real estate economic sector. Management continues to monitor these concentrations and has considered these concentrations in its allowance for loan loss analysis. The success of the Company is dependent, to a certain extent, upon the economic conditions in the geographic markets it serves. Adverse changes in the economic conditions in these geographic markets would likely have a material adverse effect on the Company’s results of operations and financial condition. The operating results of the Company depend primarily on its net interest income. Accordingly, operations are subject to risks and uncertainties surrounding the exposure to changes in the interest rate environment. At times, the Company may have cash and cash equivalents at financial institutions in excess of federal deposit insurance limits. The Company places its cash and cash equivalents with high credit quality financial institutions whose credit ratings are monitored by management to minimize credit risk. Changes in Accounting Principles and Effects of New Accounting Pronouncements ASU 2016-13, Financial Instruments – Credit Losses (Topic 326). This ASU sets forth a “current expected credit loss” (CECL) model which requires the Company to measure all expected credit losses for financial instruments held at the reporting date based on historical experience, current conditions and reasonable supported forecasts. This replaces the existing incurred loss model and is applicable to the measurement of credit losses on financial assets measured at amortized cost and applies to some off-balance sheet credit exposures. This ASU is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. On October 16, 2019, the Financial Accounting Standards Board ("FASB") voted to extend the delay of the effective date of this ASU for smaller reporting companies, such as the Company, until fiscal years beginning after December 15, 2022. The Company is currently assessing the impact of the adoption of this ASU on its consolidated financial statements. In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. This update removes several exceptions related to intraperiod tax allocation when there is a loss from continuing operations and income from other items, foreign subsidiaries becoming equity method investments and vice versa, and calculating income taxes in an interim period when a year-to-date loss exceeds the anticipated loss for the year. The guidance also amends requirements related to franchise tax that is partially based on income, a step up in the tax basis of goodwill, allocation of consolidated tax expense to a legal entity not subject to tax in its separate financial statements, the effects of enacted changes in tax laws and other minor codification improvements regarding employee stock ownership plans and investments in qualified affordable housing projects. For public entities, this guidance is effective for fiscal years beginning after December 15, 2020. The adoption of this standard did not have a material impact on the consolidated financial statements. In January 2020, the FASB issued ASU No. 2020-01, Investments—Equity Securities (Topic 321), Investments—Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815)—Clarifying the Interactions between Topic 321, Topic 323, and Topic 815 (a consensus of the Emerging Issues Task Force). This update clarifies whether an entity should consider observable transactions that require it to either apply or discontinue the equity method of accounting for the purposes of applying the measurement alternative and how to account for certain forward contracts and purchased options to purchase securities. For public entities, this guidance is effective for fiscal years beginning after December 15, 2020. The adoption of this standard did not have a material impact on the consolidated financial statements. In March 2020, the FASB issued ASU No. 2020-04, Reference Reform (Topic 848) Facilitation of the Effects of Reference Rate Reform on Financial Reporting ("ASU 2020-04"). ASU 2020-04 provides optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. The amendments are effective for the Company as of March 12, 2020 through December 31, 2022. The adoption of this standard did not have a material impact on the consolidated financial statements. Operating, Accounting and Reporting Considerations Related to COVID-19 The COVID-19 pandemic has negatively impacted the global economy, including the Company’s primary metropolitan markets. In response to this crisis, the Coronavirus Aid, Relief, and Economic Security (“CARES”) Act was passed by Congress and signed into law on March 27, 2020. The CARES Act provides an estimated $2.2 trillion to fight the COVID-19 pandemic and stimulate the economy by supporting individuals and businesses through loans, grants, tax changes, and other types of relief. Some of the provisions applicable to the Company include, but are not limited to: •Accounting for Loan Modifications - The CARES Act provides that financial institutions may elect to suspend (1) the requirements under GAAP for certain loan modifications that would otherwise by categorized as a troubled debt restructure (“TDR”) and (2) any determination that such loan modifications would be considered a TDR, including the related impairment for accounting purposes. •Paycheck Protection Program - The CARES Act established the Paycheck Protection Program (“PPP”), an expansion of the Small Business Administration’s 7(a) loan program and the Economic Injury Disaster Loan Program (“EIDL”), administered directly by the SBA. Also in response to the COVID-19 pandemic, the Board of Governors of the Federal Reserve System (“FRB”), the Federal Deposit Insurance Corporation (“FDIC”), the National Credit Union Administration (“NCUA”), the Office of the Comptroller of the Currency (“OCC”), and the Consumer Financial Protection Bureau (“CFPB”), in consultation with the state financial regulators (collectively, the “agencies”) issued a joint interagency statement (issued March 22, 2020; revised statement issued April 7, 2020). Some of the provisions applicable to the Company include, but are not limited to: •Accounting for Loan Modifications - Loan modifications that do not meet the conditions of the CARES Act may still qualify as a modification that does not need to be accounted for as a TDR. The agencies confirmed with FASB staff that short-term modifications made on a good faith basis in response to COVID-19 to borrowers who were current prior to any relief are not TDRs. This includes short-term (e.g., three months) modifications such as payment deferrals, fee waivers, extensions of repayment terms, or insignificant delays in payment, as long as such modifications are (1) related to COVID-19; (2) executed on a loan that was not more than 30 days past due as of December 31, 2019; and (3) executed between March 1, 2020, and the earlier of (a) 60 days after the date of termination of the national emergency declaration or (b) December 31, 2020. •Past Due Reporting - With regard to loans not otherwise reportable as past due, financial institutions are not expected to designate loans with deferrals granted due to COVID-19 as past due because of the deferral. A loan’s payment date is governed by the due date stipulated in the legal agreement. If a financial institution agrees to a payment deferral, these loans would not be considered past due reporting during the period of the deferral. •Nonaccrual Status and Charge-offs - During short-term COVID-19 modifications, these loans generally should not be reported as nonaccrual or as classified. As such, beginning in late March 2020, the Company provided relief programs consisting primarily of 90-day payment deferral relief of principal and interest to borrowers negatively impacted by COVID-19 and has accounted for these loan modifications in accordance with ASC 310-40. In addition, the Company also provided principal only payment deferral relief to borrowers of which interest income has been recognized during the deferment period on these interest-only loans.
