Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of Business Colony Bankcorp, Inc. and subsidiaries (the “Company”) is a financial holding company headquartered in Fitzgerald, Georgia, whose primary business is presently conducted by Colony Bank, its wholly owned banking subsidiary (the “Bank”). Through the Bank, the Company offers a broad range of retail and commercial banking services to its customers concentrated in central, south and coastal Georgia. The Bank also engages in mortgage banking and SBA lending, and, as such originates, acquires, sells and services one-to-four family residential mortgage loans and SBA loans in the Southeast. The Company is subject to the regulations of certain state and federal agencies and are periodically examined by those regulatory agencies. Basis of Presentation and Accounting Estimates The consolidated financial statements include the accounts of the Colony Bankcorp, Inc. and its wholly owned subsidiaries, Colony Bank and Colony Risk Management. All significant intercompany transactions and balances have been eliminated in consolidation. In preparing the consolidated financial statements in conformity with generally accepted accounting principles in the United States, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheet and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Acquisition Accounting Acquisitions are accounted for under the acquisition method of accounting. Purchased assets and assumed liabilities are recorded at their estimated fair values as of the purchase date. Any identifiable intangible assets are also recorded at fair value. When the consideration given is less than the fair value of the net assets received, the acquisition results in a “bargain purchase gain”. If the consideration given exceeds the fair value of the net assets received, goodwill is recognized. Fair values are subject to refinement for up to one year after the closing date of an acquisition as additional information regarding the closing date fair values becomes available. All identifiable intangible assets that are acquired in a business combination are recognized at fair value on the acquisition date. Identifiable intangible assets are recognized separately if they arise from contractual or other legal rights or if they are separable (i.e., capable of being sold, transferred, licensed, rented, or exchanged separately from the entity). Purchased loans acquired in a business combination are recorded at estimated fair value on their purchase date and carryover of the seller's related allowance for loan losses is prohibited. When the loans have evidence of credit deterioration since origination and it is probable at the date of acquisition that the Company will not collect all contractually required principal and interest payments, the difference between contractually required payments at acquisition and the cash flows expected to be collected at acquisition is referred to as the non-accretable difference. The Company must estimate expected cash flows at each reporting date. Subsequent decreases to the expected cash flows will generally result in a provision for loan losses. Subsequent increases in expected cash flows result in a reversal of the provision for loan losses to the extent of prior provisions and adjust accretable discount if no prior provisions have been made or have been fully reversed. This increase in accretable discount will have a positive impact on future interest income. Transfer of Financial Assets Transfers of financial assets are accounted for as sales, when control over the assets has been relinquished. Control over transferred assets is deemed to be surrendered when the assets have been isolated from the Company, the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity. Cash and Cash Equivalents For purposes of reporting cash flow, cash and cash equivalents include cash on hand, cash items in process of collection, amounts due from banks, interest-bearing deposits in banks and federal funds sold. The bank is required to maintain reserve balances in cash or on deposit with the Federal Reserve Bank. The daily average cash reserve requirement was temporarily suspended for the year ended December 31, 2020 due to COVID-19 crisis response and was approximately $2.7 million, at December 31, 2019, and was met by cash on hand which is reported on the Company’s consolidated balance sheets in cash and due from banks. Investment Securities The Company classifies its investment securities in one of three categories: (i) trading, (ii) held to maturity or (iii) available for sale. Trading securities are bought and held principally for the purpose of selling them in the near term. Held to maturity securities are those securities for which the Company has the ability and intent to hold until maturity. All other investment securities are classified as available for sale. At December 31, 2020 and 2019, all securities were classified as available for sale. Trading securities are carried at fair value. Unrealized gains and losses on trading securities are recorded in earnings as a component of other noninterest income. Held to maturity securities are recorded initially at cost and subsequently adjusted for paydowns and amortization of purchase premium or accretion of purchase discount. Available for sale securities are carried at fair value. Unrealized holding gains and losses, net of the related deferred tax effect, on available for sale securities are excluded from earnings and are reported in other comprehensive income as a separate component of shareholders’ equity until realized. Transfers of securities between categories are recorded at fair value at the date of transfer. Unrealized holding gains or losses associated with transfers of securities from held to maturity to available for sale are recorded as a separate component of shareholders’ equity. These unrealized holding gains or losses are amortized into income over the remaining life of the security as an adjustment to the yield in a manner consistent with the amortization or accretion of the original purchase premium or discount on the associated security. The amortization of premiums and accretion of discounts are recognized in interest income using methods approximating the interest method over the expected life of the securities. Realized gains and losses, determined on the basis of the cost of specific securities sold, are included in earnings on the trade date. A decline in the market value of any available for sale or held to maturity investment below cost that is deemed other than temporary establishes a new cost basis for the security. Other than temporary impairment deemed to be credit related is charged to earnings. Other than temporary impairment attributed to non-credit related factors is recognized in other comprehensive income. In determining whether other-than-temporary impairment losses exist, management considers (i) the length of time and the extent to which the fair value has been less than cost, (ii) the financial condition and near-term prospects of the issuer or underlying collateral of the security and (iii) the Company’s intent and ability of the Company to retain its investment in the issuer for a period of time sufficient to allow for any anticipated recovery in fair value. Other Investments Other investments include Federal Home Loan Bank (“FHLB”) and First National Bankers Bank ("FNBB") stock. These investments do not have a readily determinable market value due to restrictions placed on transferability and therefore are carried at cost. These investments are periodically evaluated for impairment based on ultimate recovery of par value or cost basis. Both cash and stock dividends are reported as income. Loans Held for Sale Mortgage and SBA loans held for sale are carried at the lower of aggregate cost or estimated fair value, as determined by outstanding commitments from third party investors in the secondary market. Adjustments to reflect unrealized gains and losses resulting from changes in fair value of mortgage loans held for sale and realized gains and losses upon ultimate sale of the mortgage loans held for sale are classified as mortgage fee income in the consolidated statements of income. Adjustments to reflect unrealized gains and losses resulting from changes in fair value of SBA loans held for sale and realized gains and losses upon ultimate sale of the SBA loans held for sale are classified as gain on sale of SBA loans in the consolidated statements of income. Loans Loans are reported at their outstanding principal balances less unearned income, net of deferred fees and origination costs. Interest income is accrued on the outstanding principal balance. For all classes of loans, the accrual of interest on loans is discontinued when, in management’s opinion, the borrower may be unable to make payments as they become due, unless the loan is well secured and in the process of collection. Non-accrual loans and loans past due 90 days still on accrual include both smaller balance homogeneous loans that are collectively evaluated for impairment and individually classified impaired loans. All interest accrued, but not collected for loans that are placed on nonaccrual or charged off, is reversed against interest income. Interest income on nonaccrual loans is applied against principal until the loans are returned to accrual status. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. Allowance for Loan Losses The allowance for loan losses is established as 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 loan balance to be uncollectable. Subsequent recoveries, if any, are credited to the allowance. The allowance for loan losses is evaluated on a regular basis by management and is based upon management’s periodic review of the collectability of the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral and prevailing economic conditions. This evaluation is inherently subjective, as it requires estimates that are susceptible to significant revisions as more information becomes available. The allowance consists of specific, historical and general components. The specific component relates to loans that are classified as either doubtful, substandard or special mention. For such loans that are also classified as impaired, an allowance is established when the discounted cash flows (or collateral value or observable market price) of the impaired loan are lower than the carrying value of that loan. The historical component covers nonclassified loans and is based on historical loss experience adjusted for qualitative factors. A general component is maintained to cover uncertainties that could affect management’s estimate of probable losses. The general component of the allowance reflects the margin of imprecision inherent in the underlying assumptions used in the methodologies for estimating specific and historical losses in the portfolio. General valuation allowances are based on internal and external qualitative risk factors such as (1) changes in lending policies and procedures, including changes in underwriting standards and collections, charge offs, and recovery practices, (2) changes in international, national, regional, and local conditions, (3) changes in the nature and volume of the portfolio and terms of loans, (4) changes in the experience, depth, and ability of lending management, (5) changes in the volume and severity of past due loans and other similar conditions, (6) changes in the quality of the organization's loan review system, (7) changes in the value of underlying collateral for collateral dependent loans, (8) the existence and effect of any concentrations of credit and changes in the levels of such concentrations, and (9) the effect of other external factors (i.e. competition, legal and regulatory requirements) on the level of estimated credit losses. Loans identified as losses by management, internal loan review and/or Bank examiners are charged off. A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record and the amount of the shortfall in relation to the principal and interest owed. Impairment is measured on a loan-by-loan basis by either the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price or the fair value of the collateral if the loan is collateral dependent. A significant portion of the Company’s impaired loans are deemed to be collateral dependent. Management therefore measures impairment on these loans based on the fair value of the collateral. Collateral values are determined based on appraisals performed by qualified licensed appraisers hired by the Company. The decision whether to obtain an external third-party appraisal usually depends on the type of property being evaluated. External appraisals are usually obtained on more complex, income producing properties such as hotels, shopping centers and businesses. Less complex properties such as residential lots, farm land and single family houses may be evaluated internally by senior credit administration staff. When the Company does obtain appraisals from external third-parties, the values utilized in the impairment calculation are “as is” or current market values. The appraisals, whether prepared internally or externally, may utilize a single valuation approach or a combination of approaches including the comparable sales, income and cost approach. Appraised amounts used in the impairment calculation are typically discounted 10 percent to account for selling and marketing costs, if the repayment of the loan is to come from the sale of the collateral. Although appraisals may not be obtained each year on all impaired loans, the collateral values used in the impairment calculations are evaluated quarterly by management. Based on management’s knowledge of the collateral and the current real estate market conditions, appraised values may be further discounted to reflect facts and circumstances known to management since the initial appraisal was performed. Adjustments are routinely made in the appraisal process by the appraisers to adjust for differences between the comparable sales and income data available. Such adjustments are typically significant and result in a level 3 classification of the inputs for determining fair value. Because of the high degree of judgment required in estimating the fair value of collateral underlying impaired loans and because of the relationship between fair value and general economic conditions, we consider the fair value of impaired loans to be highly sensitive to changes in market conditions. The restructuring of a loan is considered a “troubled debt restructuring” if both (i) the borrower is experiencing financial difficulties and (ii) the Company has granted a concession. Concessions may include interest rate reductions to below market interest rates, principal forgiveness, restructuring amortization schedules and other actions intended to minimize potential losses. The Company’s policy requires a restructure request to be supported by a current, well-documented credit evaluation of the borrower’s financial condition and a collateral evaluation that is no older than six months from the date of the restructure. The Company’s policy states in the event a loan has been identified as a troubled debt restructuring, it should be assigned a grade of substandard and placed on nonaccrual status until such time that the borrower has demonstrated the ability to service the loan payments based on the restructured terms – generally defined as six months of satisfactory payment history. The Company’s loan policy states that a nonaccrual loan may be returned to accrual status when (i) none of its principal and interest is due and unpaid, and the Company expects repayment of the remaining contractual principal and interest, or (ii) it otherwise becomes well secured and in the process of collection. Restoration to accrual status on any given loan must be supported by a well-documented credit evaluation of the borrower’s financial condition and the prospects for full repayment, approved by the Company’s Chief Credit Officer. In the normal course of business, the Company renews loans with a modification of the interest rate or terms that are not deemed as troubled debt restructurings because the borrower is not experiencing financial difficulty. Once a loan is modified in a troubled debt restructuring, it is accounted for as an impaired loan, regardless of its accrual status, until the loan is paid in full, sold or charged off. Commitments and Financial Instruments Financial instruments include off-balance sheet credit instruments, such as commitments to make loans and standby letters of credit, issued to meet customer financing needs. The face amount for these items represents the exposure to loss, before considering customer collateral or ability to repay. Such financial instruments are recorded when they are funded. Premises and Equipment Land is carried at cost. Other premises and equipment are carried at cost, less accumulated depreciation computed on the straight-line method over the estimated useful lives of the assets. In general, estimated lives for buildings are up to 40 years, furniture and equipment useful lives range from five three Goodwill and Intangible Assets Goodwill represents the excess of the cost of businesses acquired over the fair value of the net assets acquired. Goodwill is assigned to reporting units and tested for impairment at least annually, or on an interim basis if an event occurs or circumstances change that would more likely than not reduce the fair value of the reporting unit below its carrying value. Intangible assets consist of core deposit intangibles acquired in connection with a business combination. The core deposit intangible is initially recognized based on an independent valuation performed as of the acquisition date. The core deposit intangible is amortized by the straight-line method over the average remaining life of the acquired customer deposits. Cash Value of Bank Owned Life Insurance The Company has purchased life insurance policies on certain officers. The life insurance is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement. Other Real Estate Other real estate generally represents real estate acquired through foreclosure and is initially recorded at estimated fair value at the date of acquisition less the cost of disposal. Losses from the acquisition of property in full or partial satisfaction of debt are recorded as loan losses. Properties are evaluated regularly to ensure the recorded amounts are supported by current fair values, and valuation allowances are recorded as necessary to reduce the carrying amount to fair value less estimated cost of disposal. Routine holding costs and gains or losses upon disposition are included in foreclosed property expense. Income Taxes The provision for income taxes is based upon income for financial statement purposes, adjusted for nontaxable income and nondeductible expenses. Deferred income taxes have been provided when different accounting methods have been used in determining income for income tax purposes and for financial reporting purposes. Deferred tax assets and liabilities are recognized based on future tax consequences attributable to differences arising from the financial statement carrying values of assets and liabilities and their tax basis. The differences relate primarily to depreciable assets (use of different depreciation methods for financial statement and income tax purposes) and allowance for loan losses (use of the allowance method for financial statement purposes and the direct write-off method for tax purposes). In the event of changes in the tax laws, deferred tax assets and liabilities are adjusted in the period of the enactment of those changes, with effects included in the income tax provision. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized. The Company and its subsidiary file a consolidated federal income tax return. The subsidiary pays its proportional share of federal income taxes to the Company based on its taxable income. The Company’s federal and state income tax returns for tax years 2020, 2019, 2018 and 2017 are subject to examination by the Internal Revenue Service (IRS) and the Georgia Department of Revenue, generally for three years after filing. The Company believes that its income tax filing positions taken or expected to be taken on its tax returns will more likely than not be sustained upon audit by the taxing authorities and does not anticipate any adjustments that will result in a material adverse impact on the Company’s financial condition, results of operations, or cash flow. Therefore, no reserves for uncertain income tax positions have been recorded. Earnings per Share Basic earnings per share are computed by dividing net income allocated to common shareholders by the weighted-average number of shares of common stock outstanding during the period. Diluted earnings per common share are computed by dividing net income allocated to common shareholders by the sum of the weighted-average number of shares of common stock outstanding and the effect of the issuance of potential common shares that are dilutive. Potential common shares consist of restricted shares for the years ended December 31, 2020 and 2019, and are determined using the treasury stock method. The Company has determined that its outstanding non-vested stock awards are participating securities, and all dividends on these awards are paid similar to other dividends. Comprehensive Income Accounting principles generally require that recognized revenue, expenses, gains and losses be included in net income. Certain changes in assets and liabilities, such as unrealized gains and losses on securities available for sale, represent equity changes from economic events of the period other than transactions with owners. Such items are considered components of other comprehensive income (loss). Accounting standards codification requires the presentation in the consolidated financial statements of net income and all items of other comprehensive income (loss) as total comprehensive income (loss). Fair Value Measures Fair values of assets and liabilities are estimated using relevant market information and other assumptions, as more fully disclosed in a separate note. Fair value estimates involve uncertainties and matters of significant judgment regarding interest rates, credit risk, prepayments, and other factors, especially in the absence of broad markets for particular items. Changes in assumptions or in market conditions could significantly affect these estimates. Operating Segments The Company has three reportable segments, the Banking Division, the Retail Mortgage Division and the Small Business Specialty Lending Division. The Banking Division derives its revenues from the delivery of full service financial services to include commercial loans, consumer loans and deposit accounts. The Retail Mortgage Division derives its revenues from the origination, sales and servicing of one-to-four family residential mortgage loans. The Small Business Specialty Lending Division derives its revenues from origination, sales and servicing of SBA and USDA government guaranteed loans. The Banking, Retail Mortgage and Small Business Specialty Lending Divisions are managed as separate business units because of the different products and services they provide. The Company evaluates performance and allocates resources based on profit or loss from operations. There are no material intersegment sales or transfers. Reclassifications Certain amounts, previously reported, have been reclassified to state all periods on a comparable basis and had no effect on stockholders’ equity or net income. Operating, Accounting and Reporting Considerations Related to COVID-19 The COVID-19 pandemic has negatively impacted the global economy, including the Company’s market areas. 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 provided 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: a. 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. b. 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: a. 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 the Financial Accounting Standards Board (“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 at the time of modification; 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. b. 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. c. Nonaccrual Status - During short-term COVID-19 modifications, these loans generally should not be reported as nonaccrual or as classified. Beginning in late March 2020, the Company provided relief programs consisting primarily of 90 to 180 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. Accounting Standards Updates Pending Adoption In March 2020, the FASB issued updated guidance codified within ASU-2020-04, "Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting," which provide 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. In response to the risk of cessation of the London Interbank Offered Rate ("LIBOR"), regulators in several jurisdictions around the world have undertaken reference rate reform initiatives to identify alternative reference rates that are more observable, or transaction based and less susceptible to manipulation. As of December 31, 2020, the Company had $24.2 million of subordinated debentures with rates tied to LIBOR and is currently evaluating the impact of the amended guidance and has not yet determined the effect of the standard on its ongoing financial reporting. 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 Company does not expect the new guidance to have a material impact on the 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 Company does not expect the new guidance to have a material impact on the consolidated financial statements. 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 mea

Business Combinations [Abstract]
BUSINESS COMBINATIONS	BUSINESS COMBINATIONS Acquisition of LBC Bancshares, Inc. On May 1, 2019, the Company completed its acquisition of LBC Bancshares, Inc. (“LBC”), a bank holding company headquartered in LaGrange, Georgia. Upon consummation of the acquisition, LBC was merged with and into the Company, with Colony as the surviving entity in the merger. At that time, LBC’s wholly owned bank subsidiary, Calumet Bank, was also merged with and into the Bank. The acquisition expanded the Company’s market presence, as Calumet Bank had two full-service banking locations, one each in LaGrange, Georgia and Columbus, Georgia, as well as a loan production office in Atlanta, Georgia. Under the terms of the Agreement and Plan of Merger, each LBC shareholder had the option to receive either $23.50 in cash or 1.3239 shares of the Company’s common stock in exchange for each share of LBC common stock, such that 55 percent of LBC shares of common stock received the stock consideration and 45 percent received the cash consideration, with at least 50 percent of the merger consideration paid in the Company's common stock. As a result, the Company issued 1,053,875 common shares at a fair value of $18.7 million and paid $15.3 million in cash to the former shareholders of LBC as merger consideration. The merger was effected by the issuance of shares of the Company’s common stock along with cash consideration to shareholders to LBC. The assets and liabilities of LBC as of the effective date of the merger were recorded at their respective estimated fair values and combined with those of the Company. The excess of the purchase price over the net estimated fair values of the acquired assets and liabilities was allocated to identifiable intangible assets with the remaining excess allocated to goodwill. Goodwill of $15.7 million was recorded as part of the LBC acquisition and is not expected to be deductible for income tax purposes. The following table presents the assets acquired and liabilities assumed of LBC as of May 1, 2019, and their fair value estimates. The fair value estimates were subject to refinement for up to one year after the closing date of the acquisition for new information obtained about facts and circumstances that existed at the acquisition date.

In the acquisition, the Company purchased $130.6 million of loans at fair value, net of $2.2 million, or 1.63%, estimated discount to the outstanding principal balance. Of the total loans acquired, management identified $176,000 that were considered to be credit impaired and are accounted for under ASC Topic 310 -30.

Consideration is given to (1) the length of time and the extent to which the fair value has been less than cost, (2) the financial condition and near-term prospects of the issuer and (3) the intent and ability of the Company to retain its investment in the issuer for a period of time sufficient to allow for any anticipated recovery in fair value. At December 31, 2020, twenty securities have unrealized losses from the Company’s amortized cost basis. These securities are guaranteed by either the U.S. Government, other governments or U.S. corporations. In analyzing an issuer’s financial condition, management considers whether the securities are issued by the federal government or its agencies, whether downgrades by bond rating agencies have occurred and the results of reviews of the issuer’s financial condition. The unrealized losses are largely due to increases in market interest rates over the yields available at the time the underlying securities were purchased. As management has the ability to hold debt securities until maturity, or for the foreseeable future if classified as available-for-sale, no declines are deemed to be other than temporary. The amortized cost and fair value of investment securities as of December 31, 2020, by contractual maturity, are shown hereafter. Expected maturities may differ from contractual maturities for certain investments because issuers may have the right to call or prepay obligations with or without call or prepayment penalties. This is often the case with mortgage-backed securities, which are disclosed separately in the table below.

Commercial and agricultural loans are extended to a diverse group of businesses within the Company’s market area. These loans are often underwritten based on the borrower’s ability to service the debt from income from the business. Real estate construction loans often require loan funds to be advanced prior to completion of the project. Due to uncertainties inherent in estimating construction costs, changes in interest rates and other economic conditions, these loans often pose a higher risk than other types of loans. Consumer loans are originated at the bank level. These loans are generally smaller loan amounts spread across many individual borrowers to help minimize risk. Credit Quality Indicators. As part of the ongoing monitoring of the credit quality of the loan portfolio, management tracks certain credit quality indicators including trends related to (1) the risk grade assigned to commercial and consumer loans, (2) the level of classified commercial loans, (3) net charge-offs, (4) nonperforming loans, and (5) the general economic conditions in the Company’s geographic markets. The Company uses a risk grading matrix to assign a risk grade to each of its loans. Loans are graded on a scale of 1 to 8. A description of the general characteristics of the grades is as follows: • Grades 1 and 2 - Borrowers with these assigned grades range in risk from virtual absence of risk to minimal risk. Such loans may be secured by Company-issued and controlled certificates of deposit or properly margined equity securities or bonds. Other loans comprising these grades are made to companies that have been in existence for a long period of time with many years of consecutive profits and strong equity, good liquidity, excellent debt service ability and unblemished past performance, or to exceptionally strong individuals with collateral of unquestioned value that fully secures the loans. Loans in this category fall into the “pass” classification. • Grades 3 and 4 - Loans assigned these “pass” risk grades are made to borrowers with acceptable credit quality and risk. The risk ranges from loans with no significant weaknesses in repayment capacity and collateral protection to acceptable loans with one or more risk factors considered to be more than average. • Grade 5 - This grade includes “special mention” loans on management’s watch list and is intended to be used on a temporary basis for pass grade loans where risk-modifying action is intended in the short-term. • Grade 6 - This grade includes “substandard” loans in accordance with regulatory guidelines. This category includes borrowers with well-defined weaknesses that jeopardize the payment of the debt in accordance with the agreed terms. Loans considered to be impaired are assigned this grade, and these loans often have assigned loss allocations as part of the allowance for loan and lease losses. Generally, loans on which interest accrual has been stopped would be included in this grade. • Grades 7 and 8 - These grades correspond to regulatory classification definitions of “doubtful” and “loss,” respectively. In practice, any loan with these grades would be for a very short period of time, and generally the Company has no loans with these assigned grades. Management manages the Company’s problem loans in such a way that uncollectible loans or uncollectible portions of loans are charged off immediately with any residual, collectible amounts assigned a risk grade of 6. The following tables present the loan portfolio, excluding purchased loans, by credit quality indicator (risk grade) as of December 31, 2020. Those loans with a risk grade of 1, 2, 3 or 4 have been combined in the pass column for presentation purposes. For the periods ending December 31, 2020, the Company did not have any loans classified as “doubtful” or a “loss”.

Loan risk grades are subject to reassessment at various times throughout the year as part of the Company’s ongoing loan review process. Loans with an assigned risk grade of 6 or below and an outstanding balance of $250,000 or more are reassessed on a quarterly basis. During this reassessment process individual reserves may be identified and placed against certain loans which are not considered impaired. In assessing the overall economic condition of the markets in which it operates, the Company monitors the unemployment rates for its major service areas. The unemployment rates are reviewed on a quarterly basis as part of the allowance for loan loss determination. Loans are considered past due if the required principal and interest payments have not been received as of the date such payments were due. Generally, loans are placed on nonaccrual status if principal or interest payments become 90 days past due or when, in management’s opinion, the borrower may be unable to meet payment obligations as they become due, as well as when required by regulatory provision. Loans may be placed on nonaccrual status regardless of whether such loans are considered past due.

Had nonaccrual loans performed in accordance with their original contractual terms, the Company would have recognized additional interest income of approximately $221,000 for the year ended December 31, 2019. Troubled Debt Restructurings (TDRs) are troubled loans on which the original terms of the loan have been modified in favor of the borrower due to deterioration in the borrower’s financial condition. Each potential loan modification is reviewed individually and the terms of the loan are modified to meet the borrower’s specific circumstances at a point in time. Not all loan modifications are TDRs. Loan modifications are reviewed and approved by the Company’s senior lending staff, who then determine whether the loan meets the criteria for a TDR. Generally, the types of concessions granted to borrowers that are evaluated in determining whether a loan is classified as a TDR include: • Interest rate reductions - Occur when the stated interest rate is reduced to a nonmarket rate or a rate the borrower would not be able to obtain elsewhere under similar circumstances. • Amortization or maturity date changes - Result when the amortization period of the loan is extended beyond what is considered a normal amortization period for loans of similar type with similar collateral. • Principal reductions - These are often the result of commercial real estate loan workouts where two new notes are created. The primary note is underwritten based upon the Company’s normal underwriting standards and is structured so that the projected cash flows are sufficient to repay the contractual principal and interest of the newly restructured note. The terms of the secondary note vary by situation and often involve that note being charged off, or the principal and interest payments being deferred until after the primary note has been repaid. In situations where a portion of the note is charged off during modification, there is often no specific reserve allocated to those loans. This is due to the fact that the amount of the charge-off usually represents the excess of the original loan balance over the collateral value and the Company has determined there is no additional exposure on those loans. As discussed in Note 1, Summary of Significant Accounting Policies, once a loan is identified as a TDR, it is accounted for as an impaired loan. The Company had no unfunded commitments to lend to a customer that has a troubled debt restructured loan as of December 31, 2020. The Company had four loan contracts totaling $494,000 restructured during 2020. Loans modified in a troubled debt restructuring are considered to be in default once the loan becomes 90 days past due. A TDR may cease being classified as impaired if the loan is subsequently modified at market terms and, has performed according to the modified terms for at least six months, and there has not been any prior principal forgiveness on a cumulative basis. The Company had four loan contracts restructured during the year ended December 31, 2020, all four modifications were payment deferral modifications. The loans consisted of two commercial real estate loans totaling $132,000, one commercial loan totaling $89,000 and one residential real estate loan totaling $273,000. Loans modified in a troubled debt restructuring are considered to be in default once the loan becomes 90 days past due. A TDR may cease being classified as impaired if the loan is subsequently modified at market terms and, has performed according to the modified terms for at least six months, and there has not been any prior principal forgiveness on a cumulative basis. The Company had no loan contracts restructured during 2019. During 2019, the Company had one loan totaling $859,000 that subsequently defaulted. This loan failed to continue to perform as agreed and was moved to non-accrual status. Modifications in Response to COVID-19 Certain borrowers are currently unable to meet their contractual payment obligations because of the adverse effects of the COVID-19 pandemic. To help mitigate these effects, loan customers may apply for a deferral of payments, or portions thereof, for up to three months. In the absence of other intervening factors, such short-term modifications made on a good faith basis are not categorized as troubled debt restructurings, nor are loans granted payment deferrals related to the COVID-19 pandemic reported as past due or placed on nonaccrual status (provided the loans were not past due or on nonaccrual status prior to the deferral). As of December 31, 2020, the Company had approximately $1.9 million in loans still under their modified terms. The Company’s modification program included payment deferrals, interest only, and other forms of modifications. See Note 1 - Summary of Significant Accounting Policies for more information.

Leases [Abstract]
LEASES	LEASES A lease is defined as a contract, or part of a contract, that conveys the right to control the use of identified property, plant or equipment for a period of time in exchange for consideration. On January 1, 2019, the Company adopted ASU No. 2016-2 and all subsequent ASUs that modified this topic (collectively referred to as “Topic 842”). For the Company, Topic 842 primarily affected the accounting treatment for operating lease agreements in which the Company is the lessee. Substantially all of the leases in which the Company is the lessee are comprised of real estate for branches and office space with terms extending through 2027. All of our leases are classified as operating leases, and therefore, were previously not recognized on the Company’s consolidated balance sheet. With the adoption of Topic 842, operating lease arrangements are required to be recognized on the consolidated balance sheet as a right-of-use (“ROU”) asset and a corresponding lease liability. The following table represents the consolidated balance sheet classification of the Company’s ROU assets and liabilities. The Company elected not to include short-term leases (i.e., leases with initial terms of twelve months or less), or equipment leases (deemed immaterial) on the consolidated balance sheet. (dollars in thousands) Classification December 31, 2020 December 31, 2019 Assets Operating lease right-of-use assets Other assets $ 511 $ 572 Liabilities Operating lease liabilities Other liabilities $ 517 $ 547 The calculated amount of the ROU assets and lease liabilities in the table above are impacted by the length of the lease term and the discount rate used to present value the minimum lease payments. The Company’s lease agreements often include one or more options to renew at the Company’s discretion. If at lease inception the Company considers the exercising of a renewal option to be reasonably certain, the Company will include the extended term in the calculation of the ROU asset and lease liability. Regarding the discount rate, Topic 842 requires the use of the rate implicit in the lease whenever this rate is readily determinable. As this rate is rarely determinable, the Company utilizes its incremental borrowing rate at lease inception, on a collateralized basis, over a similar term. For operating leases existing prior to January 1, 2019, the rate for the remaining lease term as of January 1, 2019 was used. For the year ended December 31, 2020 and 2019, operating lease cost was $243,000 and $152,000, respectively. As of December 31, 2020, the weighted average remaining lease term was 4.55 years and the weighted average discount rate was 1.75%. The following table represents the future maturities of the Company’s operating lease liabilities and other lease information.

Retirement Benefits [Abstract]
COMPENSATION PLANS	COMPENSATION PLANS The Company offers a defined contribution 401(k) Profit Sharing Plan (the Plan) which covers substantially all employees who meet certain age and service requirements. The Plan allows employees to make voluntary pre-tax salary deferrals to the Plan. The Company, at its discretion, may elect to make an annual contribution to the Plan equal to a percentage of each participating employee’s salary. Such discretionary contributions must be approved by the Company’s board of directors. Employees are fully vested in the Company contributions after six years of service. In 2020 and 2019, the Company made total contributions of $1.1 million and $674,000 to the Plan, respectively. Colony Bank, the wholly-owned subsidiary, has deferred compensation plans covering certain former directors and certain officers choosing to participate through individual deferred compensation contracts. In accordance with terms of the contracts, the Bank is committed to pay the participant’s deferred compensation over a specified number of years, beginning at age 65. In the event of a participant’s death before age 65, payments are made to the participant’s named beneficiary over a specified number of years, beginning on the first day of the month following the death of the participant. Liabilities accrued under the plans totaled $698,000 and $774,000 as of December 31, 2020 and 2019, respectively. Benefit payments under the contracts were $153,000 in 2020 and $82,000 in 2019. Provisions charged to operations totaled $75,000 in 2020 and $63,000 in 2019. The Company has purchased life insurance policies on the plans’ participants and uses the cash flow from these policies to partially fund the plan. Fee income recognized with these plans totaled $212,000 in 2020 and $157,000 in 2019. In August 2018, the Company granted an award of 5,650 restricted shares of the Company’s common stock to T. Heath Fountain, the Company’s Chief Executive Officer (“CEO”), with a market price of $17.73 per share. The restricted shares vest in equal installments on each of July 30, 2019, 2020 and 2021, subject to continued service by Mr. Fountain through each applicable vesting date, or earlier upon the occurrence of a change in control. With the restricted stock, there will be no cash consideration to the Company for the shares. The CEO will have the right to vote all shares subject to such grant and receive all dividends with respect to such shares, whether or not the shares have vested. Compensation expense for restricted stock is based on the market price of the Company stock at the time of the grant and amortized on a straight-line basis over the vesting period. The balance of unearned compensation related to these restricted shares as of December 31, 2020 is $19,000 which is expected to be recognized over a weighted-average of 0.58 years. Total compensation expense recognized for the restricted shares granted for the year ended December 31, 2020 and 2019 was $33,000 and $34,000, respectively.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Credit-Related Financial Instruments. The Company is a party to credit-related financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit, standby letters of credit and commercial letters of credit. Such commitments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the consolidated balance sheets. The Company’s exposure to credit loss is represented by the contractual amount of these commitments. The Company follows the same credit policies in making commitments as it does for on-balance sheet instruments. At December 31, 2020 and 2019, the following financial instruments were outstanding whose contract amounts represent credit risk: Contract Amount 2020 2019 (dollars in thousands) Commitments to extend credit $ 198,029 $ 102,890 Standby letters of credit 3,634 1,576 Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. The commitments for equity lines of credit may expire without being drawn upon. Therefore, the total commitment amounts do not necessarily represent future cash requirements. The amount of collateral obtained, if it is deemed necessary by the Company, is based on management’s credit evaluation of the customer. Unfunded commitments under commercial lines of credit, revolving credit lines and overdraft protection agreements are commitments for possible future extensions of credit to existing customers. These lines of credit are uncollateralized and usually do not contain a specified maturity date and may not be drawn upon to the total extent to which the Company is committed. Standby and performance letters of credit are conditional lending commitments issued by the Company to guarantee the performance of a customer to a third party. Those letters of credit are primarily issued to support public and private borrowing arrangements. Essentially all letters of credit issued have expiration dates within one year. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. Legal Contingencies. In the ordinary course of business, there are various legal proceedings pending against Colony and its subsidiaries. The aggregate liabilities, if any, arising from such proceedings would not, in the opinion of management, have a material adverse effect on Colony’s consolidated financial position.

Fair Value Disclosures [Abstract]
FAIR VALUE OF FINANCIAL INSTRUMENTS AND FAIR VALUE MEASUREMENTS	FAIR VALUE OF FINANCIAL INSTRUMENTS AND FAIR VALUE MEASUREMENTS Generally accepted accounting standards in the U.S. require disclosure of fair value information about financial instruments, whether or not recognized on the face of the balance sheet, for which it is practicable to estimate that value. The assumptions used in the estimation of the fair value of Colony Bancorp, Inc. and subsidiaries financial instruments are detailed hereafter. Where quoted prices are not available, fair values are based on estimates using discounted cash flows and other valuation techniques. The use of discounted cash flows can be significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. Generally accepted accounting principles related to Fair Value Measurements define fair value, establish a framework for measuring fair value, establish a three-level valuation hierarchy for disclosure of fair value measurement and enhance disclosure requirements for fair value measurements. The valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. The three levels are defined as follows: • Level 1 inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets. • Level 2 inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument. • Level 3 inputs to the valuation methodology are unobservable and represent the Company’s own assumptions about the assumptions that market participants would use in pricing the assets or liabilities. The following disclosures should not be considered a surrogate of the liquidation value of the Company, but rather a good-faith estimate of the increase or decrease in value of financial instruments held by the Company since purchase, origination or issuance. Cash and short-term investments - For cash, due from banks, bank-owned deposits and federal funds sold, the carrying amount is a reasonable estimate of fair value and is classified Level 1. Investment securities - Fair values for investment securities are based on quoted market prices where available and classified as Level 1. If quoted market prices are not available, estimated fair values are based on quoted market prices of comparable instruments and classified as Level 2. If a comparable is not available, the investment securities are classified as Level 3. Other investments at cost - The fair value of other bank stock approximates carrying value and is classified as Level 1. Loans held for sale – The fair value of loans held for sale is determined on outstanding commitments from third party investors in the secondary markets and is classified within Level 2 of the valuation hierarchy. Loans - The fair value of fixed rate loans is estimated by discounting the future cash flows using the current rates at which similar loans would be made to borrowers with similar credit ratings. For variable rate loans, the carrying amount is a reasonable estimate of fair value. Most loans are classified as Level 2, but impaired loans with a related allowance are classified as Level 3. Deposit liabilities - The fair value of demand deposits, savings accounts and certain money market deposits is the amount payable on demand at the reporting date and is classified as Level 1. The fair value of fixed maturity certificates of deposit is estimated by discounting the future cash flows using the rates currently offered for deposits of similar remaining maturities and is classified as Level 2. Federal Home Loan Bank advances – The fair value of Federal Home Loan Bank advances is estimated by discounting the future cash flows using the current rates at which similar advances would be obtained. Federal Home Loan Bank advances are classified as Level 2. Paycheck Protection Liquidity Facility – The fair value of Paycheck Protection Liquidity Facility is estimated by discounting the future cash flows using the current rates at which similar advances would be obtained. Paycheck Protection Liquidity Facility are classified as Level 2. Other borrowings – The fair value of other borrowings is calculated by discounting contractual cash flows using an estimated interest rate based on current rates available to the Company for debt of similar remaining maturities and collateral terms. Other borrowings is classified as Level 2 due to their expected maturities. Disclosures of the fair value of financial assets and financial liabilities, including those financial assets and financial liabilities that are not measured and reported at fair value on a recurring basis or non-recurring basis, are required in the financial statements. The carrying amount, estimated fair values, and placement in the fair value hierarchy of the Company’s financial instruments are as follows: Carrying Estimated Level (dollars in thousands) Amount Fair Value 1 2 3 December 31, 2020 Assets Cash and short-term investments $ 183,506 $ 183,506 $ 183,506 $ — $ — Investment securities available for sale 380,814 380,814 245 380,569 — Other investments at cost 3,296 3,296 — 3,296 — Loans held for sale 52,386 52,386 — 52,386 — Loans, net 1,047,376 1,063,785 — — 1,063,785 Liabilities Deposits 1,445,027 1,445,984 — 1,445,984 — Federal Home Loan Bank advances 22,500 20,817 — 20,817 — PPPLF 106,789 106,789 — 106,789 — Other borrowed money 37,792 37,792 — 37,792 — December 31, 2019 Assets Cash and short-term investments $ 104,092 $ 104,092 $ 104,092 $ — $ — Investment securities available for sale 347,332 347,332 — 345,310 2,022 Other investments at cost 4,288 4,288 — 4,288 — Loans held for sale 10,076 10,076 — 10,076 — Loans, net 961,951 938,475 — — 938,475 Liabilities Deposits 1,293,742 1,294,506 — 1,294,506 — Federal Home Loan Bank advances 47,000 46,022 — 46,022 — Other borrowed money 38,792 38,792 — 38,792 — Fair value estimates are made at a specific point in time, based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time the Company’s entire holdings of a particular financial instrument. Because no market exists for a significant portion of the Company’s financial instruments, fair value estimates are based on many judgments. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. Changes in assumptions could significantly affect the estimates. Fair value estimates are based on existing on- and off-balance sheet financial instruments without attempting to estimate the value of anticipated future business and the value of assets and liabilities that are not considered financial instruments. Significant assets and liabilities that are not considered financial instruments include deferred income taxes and premises and equipment. In addition, the tax ramifications related to the realization of the unrealized gains and losses can have a significant effect on fair value estimates and have not been considered in the estimates. Following is a description of the valuation methodologies used for instruments measured at fair value on a recurring and nonrecurring basis, as well as the general classification of such instruments pursuant to the valuation hierarchy: Impaired Loans - Impaired loans are those loans which the Company has measured impairment generally based on the fair value of the loan’s collateral. Fair value is generally determined based upon independent third-party appraisals of the properties, or discounted cash flows based upon the expected proceeds. These assets are included as level 3 fair values, based upon the lowest level of input that is significant to the fair value measurements. Other Real Estate - Other real estate owned assets are adjusted to fair value less estimated selling costs upon transfer of the loans to other real estate owned. Typically, an external, third-party appraisal is performed on the collateral upon transfer into the other real estate owned account to determine the asset’s fair value. Subsequent adjustments to the collateral’s value may be based upon either updated third-party appraisals or management’s knowledge of the collateral and the current real estate market conditions. Appraised amounts used in determining the asset’s fair value, whether internally or externally prepared, are discounted 10 percent to account for selling and marketing costs. Adjustments are routinely made in the appraisal process by the appraisers to adjust for differences between the comparable sales and income data available. Such adjustments are typically significant and result in a level 3 classification of the inputs for determining fair value. Because of the high degree of judgment required in estimating the fair value of other real estate owned assets and because of the relationship between fair value and general economic conditions, we consider the fair value of other real estate owned assets to be highly sensitive to changes in market conditions. Assets Measured at Fair Value on a Recurring and Nonrecurring Basis - The following table presents the recorded amount of the Company’s assets measured at fair value on a recurring and nonrecurring basis as of December 31, 2020 and 2019, aggregated by the level in the fair value hierarchy within which those measurements fall. The table below includes only impaired loans with a specific reserve and only other real estate properties with a valuation allowance at December 31, 2020 and 2019. Those impaired loans and other real estate properties are shown net of the related specific reserves and valuation allowances.

Banking And Thrift Disclosure [Abstract]
REGULATORY CAPITAL MARKETS	REGULATORY CAPITAL MARKETS The amount of dividends payable to the parent company from the subsidiary bank is limited by various banking regulatory agencies. Upon approval by regulatory authorities, the Bank may pay cash dividends to the parent company in excess of regulatory limitations. The Company is subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and, possibly, additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s consolidated financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company must meet specific capital guidelines that involve quantitative measures of the Company’s assets, liabilities and certain off-balance sheet items as calculated under regulatory accounting practices. The Company’s capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors. Quantitative measures established by regulation to ensure capital adequacy require the Company to maintain minimum amounts and ratios of total and Tier I capital to risk-weighted assets, and of Tier I capital to average assets. As of December 31, 2020, the interim final Basel III rules (Basel III) require the Company to also maintain minimum amounts and ratios of common equity Tier 1 capital to risk weighted assets. These amounts and ratios as defined in regulations are presented hereafter. Management believes, as of December 31, 2020, the Company meets all capital adequacy requirements to which it is subject under the regulatory framework for prompt corrective action. In the opinion of management, there are no conditions or events since prior notification of capital adequacy from the regulators that have changed the institution’s category. The Basel III rules also require the implementation of a new capital conservation buffer comprised of common equity Tier 1 capital. The capital conservation buffer was phased in beginning January 1, 2016 at 0.625 percent of risk-weighted assets, with subsequent increases of 0.625 percent each year until reaching its final level of 2.5 percent on January 1, 2019. The Bank is participating in the PPP and the PPPLF to fund PPP Loans. In accordance with regulatory guidance, PPP loans pledged as collateral for PPPLF, and PPPLF advances, are excluded from leverage capital ratios. PPP loans will also carry a 0% risk-weight for risk-based capital rules. The following table summarizes regulatory capital information as of December 31, 2020 and December 31, 2019 on a consolidated basis and for the subsidiary, as defined. Regulatory capital ratios for December 31, 2020 and 2019 were calculated in accordance with the Basel III rules.

Segment Reporting [Abstract]
SEGMENT INFORMATION	SEGMENT INFORMATION The Company’s operating segments include banking, mortgage banking and small business specialty lending division. The reportable segments are determined by the products and services offered, and internal reporting. The Bank segment derives its revenues from the delivery of full-service financial services, including retail and commercial banking services and deposit accounts. The Mortgage Banking segment derives its revenues from the origination and sales of residential mortgage loans held for sale. The Small Business Specialty Lending Division segment derives its revenue from the origination, sales and servicing of Small Business Administration loans and other government guaranteed loans. Segment performance is evaluated using net interest income and noninterest income. Income taxes are allocated based on income before income taxes, and indirect expenses (includes management fees) are allocated based on various internal factors for each segment. Transactions among segments are made at fair value. The following tables present information reported internally for performance assessment as of December 31, 2020 and 2019: December 31, 2020 (dollars in thousands) Bank Mortgage Small Totals Net Interest Income $ 54,089 $ 603 $ 553 $ 55,245 Provision for Loan Losses 6,558 — — 6,558 Noninterest Income 13,288 9,106 1,850 24,244 Noninterest Expenses 46,990 8,137 3,174 58,301 Income Taxes 2,653 324 (162) 2,815 Net income/(loss) $ 11,176 $ 1,248 $ (609) $ 11,815 Total assets $ 1,709,696 $ 50,266 $ 4,012 $ 1,763,974 December 31, 2019 (dollars in thousands) Bank Mortgage Small Totals Net Interest Income $ 47,681 $ 164 $ — $ 47,845 Provision for Loan Losses 1,104 — — 1,104 Noninterest Income 10,865 3,139 — 14,004 Noninterest Expenses 43,666 3,257 1,213 48,136 Income Taxes 2,642 10 (254) 2,398 Net income/(loss) $ 13,217 $ 36 $ (959) $ 10,211 Total assets $ 1,503,284 $ 11,624 $ 405 $ 1,515,313

Summary of Significant Accounting Policies (Policies)	12 Months Ended

Accounting Policies [Abstract]
Nature of Business	Nature of Business Colony Bankcorp, Inc. and subsidiaries (the “Company”) is a financial holding company headquartered in Fitzgerald, Georgia, whose primary business is presently conducted by Colony Bank, its wholly owned banking subsidiary (the “Bank”). Through the Bank, the Company offers a broad range of retail and commercial banking services to its customers concentrated in central, south and coastal Georgia. The Bank also engages in mortgage banking and SBA lending, and, as such originates, acquires, sells and services one-to-four family residential mortgage loans and SBA loans in the Southeast. The Company is subject to the regulations of certain state and federal agencies and are periodically examined by those regulatory agencies.
Basis of Presentation and Accounting Estimates	Basis of Presentation and Accounting Estimates The consolidated financial statements include the accounts of the Colony Bankcorp, Inc. and its wholly owned subsidiaries, Colony Bank and Colony Risk Management. All significant intercompany transactions and balances have been eliminated in consolidation. In preparing the consolidated financial statements in conformity with generally accepted accounting principles in the United States, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheet and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Acquisition Accounting	Acquisition Accounting Acquisitions are accounted for under the acquisition method of accounting. Purchased assets and assumed liabilities are recorded at their estimated fair values as of the purchase date. Any identifiable intangible assets are also recorded at fair value. When the consideration given is less than the fair value of the net assets received, the acquisition results in a “bargain purchase gain”. If the consideration given exceeds the fair value of the net assets received, goodwill is recognized. Fair values are subject to refinement for up to one year after the closing date of an acquisition as additional information regarding the closing date fair values becomes available. All identifiable intangible assets that are acquired in a business combination are recognized at fair value on the acquisition date. Identifiable intangible assets are recognized separately if they arise from contractual or other legal rights or if they are separable (i.e., capable of being sold, transferred, licensed, rented, or exchanged separately from the entity). Purchased loans acquired in a business combination are recorded at estimated fair value on their purchase date and carryover of the seller's related allowance for loan losses is prohibited. When the loans have evidence of credit deterioration since origination and it is probable at the date of acquisition that the Company will not collect all contractually required principal and interest payments, the difference between contractually required payments at acquisition and the cash flows expected to be collected at acquisition is referred to as the non-accretable difference. The Company must estimate expected cash flows at each reporting date. Subsequent decreases to the expected cash flows will generally result in a provision for loan losses. Subsequent increases in expected cash flows result in a reversal of the provision for loan losses to the extent of prior provisions and adjust accretable discount if no prior provisions have been made or have been fully reversed. This increase in accretable discount will have a positive impact on future interest income.
Transfer of Financial Assets	Transfer of Financial Assets
Cash and Cash Equivalents	Cash and Cash Equivalents For purposes of reporting cash flow, cash and cash equivalents include cash on hand, cash items in process of collection, amounts due from banks, interest-bearing deposits in banks and federal funds sold.
Investment Securities	Investment Securities The Company classifies its investment securities in one of three categories: (i) trading, (ii) held to maturity or (iii) available for sale. Trading securities are bought and held principally for the purpose of selling them in the near term. Held to maturity securities are those securities for which the Company has the ability and intent to hold until maturity. All other investment securities are classified as available for sale. At December 31, 2020 and 2019, all securities were classified as available for sale. Trading securities are carried at fair value. Unrealized gains and losses on trading securities are recorded in earnings as a component of other noninterest income. Held to maturity securities are recorded initially at cost and subsequently adjusted for paydowns and amortization of purchase premium or accretion of purchase discount. Available for sale securities are carried at fair value. Unrealized holding gains and losses, net of the related deferred tax effect, on available for sale securities are excluded from earnings and are reported in other comprehensive income as a separate component of shareholders’ equity until realized. Transfers of securities between categories are recorded at fair value at the date of transfer. Unrealized holding gains or losses associated with transfers of securities from held to maturity to available for sale are recorded as a separate component of shareholders’ equity. These unrealized holding gains or losses are amortized into income over the remaining life of the security as an adjustment to the yield in a manner consistent with the amortization or accretion of the original purchase premium or discount on the associated security. The amortization of premiums and accretion of discounts are recognized in interest income using methods approximating the interest method over the expected life of the securities. Realized gains and losses, determined on the basis of the cost of specific securities sold, are included in earnings on the trade date. A decline in the market value of any available for sale or held to maturity investment below cost that is deemed other than temporary establishes a new cost basis for the security. Other than temporary impairment deemed to be credit related is charged to earnings. Other than temporary impairment attributed to non-credit related factors is recognized in other comprehensive income. In determining whether other-than-temporary impairment losses exist, management considers (i) the length of time and the extent to which the fair value has been less than cost, (ii) the financial condition and near-term prospects of the issuer or underlying collateral of the security and (iii) the Company’s intent and ability of the Company to retain its investment in the issuer for a period of time sufficient to allow for any anticipated recovery in fair value.
Other Investments	Other Investments Other investments include Federal Home Loan Bank (“FHLB”) and First National Bankers Bank ("FNBB") stock. These investments do not have a readily determinable market value due to restrictions placed on transferability and therefore are carried at cost. These investments are periodically evaluated for impairment based on ultimate recovery of par value or cost basis. Both cash and stock dividends are reported as income.
Loans Held for Sale	Loans Held for SaleMortgage and SBA loans held for sale are carried at the lower of aggregate cost or estimated fair value, as determined by outstanding commitments from third party investors in the secondary market. Adjustments to reflect unrealized gains and losses resulting from changes in fair value of mortgage loans held for sale and realized gains and losses upon ultimate sale of the mortgage loans held for sale are classified as mortgage fee income in the consolidated statements of income. Adjustments to reflect unrealized gains and losses resulting from changes in fair value of SBA loans held for sale and realized gains and losses upon ultimate sale of the SBA loans held for sale are classified as gain on sale of SBA loans in the consolidated statements of income.
Loans	Loans Loans are reported at their outstanding principal balances less unearned income, net of deferred fees and origination costs. Interest income is accrued on the outstanding principal balance. For all classes of loans, the accrual of interest on loans is discontinued when, in management’s opinion, the borrower may be unable to make payments as they become due, unless the loan is well secured and in the process of collection. Non-accrual loans and loans past due 90 days still on accrual include both smaller balance homogeneous loans that are collectively evaluated for impairment and individually classified impaired loans. All interest accrued, but not collected for loans that are placed on nonaccrual or charged off, is reversed against interest income. Interest income on nonaccrual loans is applied against principal until the loans are returned to accrual status. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured.
Allowance for Loan Losses	Allowance for Loan Losses The allowance for loan losses is established as 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 loan balance to be uncollectable. Subsequent recoveries, if any, are credited to the allowance. The allowance for loan losses is evaluated on a regular basis by management and is based upon management’s periodic review of the collectability of the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral and prevailing economic conditions. This evaluation is inherently subjective, as it requires estimates that are susceptible to significant revisions as more information becomes available. The allowance consists of specific, historical and general components. The specific component relates to loans that are classified as either doubtful, substandard or special mention. For such loans that are also classified as impaired, an allowance is established when the discounted cash flows (or collateral value or observable market price) of the impaired loan are lower than the carrying value of that loan. The historical component covers nonclassified loans and is based on historical loss experience adjusted for qualitative factors. A general component is maintained to cover uncertainties that could affect management’s estimate of probable losses. The general component of the allowance reflects the margin of imprecision inherent in the underlying assumptions used in the methodologies for estimating specific and historical losses in the portfolio. General valuation allowances are based on internal and external qualitative risk factors such as (1) changes in lending policies and procedures, including changes in underwriting standards and collections, charge offs, and recovery practices, (2) changes in international, national, regional, and local conditions, (3) changes in the nature and volume of the portfolio and terms of loans, (4) changes in the experience, depth, and ability of lending management, (5) changes in the volume and severity of past due loans and other similar conditions, (6) changes in the quality of the organization's loan review system, (7) changes in the value of underlying collateral for collateral dependent loans, (8) the existence and effect of any concentrations of credit and changes in the levels of such concentrations, and (9) the effect of other external factors (i.e. competition, legal and regulatory requirements) on the level of estimated credit losses. Loans identified as losses by management, internal loan review and/or Bank examiners are charged off. A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record and the amount of the shortfall in relation to the principal and interest owed. Impairment is measured on a loan-by-loan basis by either the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price or the fair value of the collateral if the loan is collateral dependent. A significant portion of the Company’s impaired loans are deemed to be collateral dependent. Management therefore measures impairment on these loans based on the fair value of the collateral. Collateral values are determined based on appraisals performed by qualified licensed appraisers hired by the Company. The decision whether to obtain an external third-party appraisal usually depends on the type of property being evaluated. External appraisals are usually obtained on more complex, income producing properties such as hotels, shopping centers and businesses. Less complex properties such as residential lots, farm land and single family houses may be evaluated internally by senior credit administration staff. When the Company does obtain appraisals from external third-parties, the values utilized in the impairment calculation are “as is” or current market values. The appraisals, whether prepared internally or externally, may utilize a single valuation approach or a combination of approaches including the comparable sales, income and cost approach. Appraised amounts used in the impairment calculation are typically discounted 10 percent to account for selling and marketing costs, if the repayment of the loan is to come from the sale of the collateral. Although appraisals may not be obtained each year on all impaired loans, the collateral values used in the impairment calculations are evaluated quarterly by management. Based on management’s knowledge of the collateral and the current real estate market conditions, appraised values may be further discounted to reflect facts and circumstances known to management since the initial appraisal was performed. Adjustments are routinely made in the appraisal process by the appraisers to adjust for differences between the comparable sales and income data available. Such adjustments are typically significant and result in a level 3 classification of the inputs for determining fair value. Because of the high degree of judgment required in estimating the fair value of collateral underlying impaired loans and because of the relationship between fair value and general economic conditions, we consider the fair value of impaired loans to be highly sensitive to changes in market conditions.
Commitments and Financial Instruments	Commitments and Financial Instruments Financial instruments include off-balance sheet credit instruments, such as commitments to make loans and standby letters of credit, issued to meet customer financing needs. The face amount for these items represents the exposure to loss, before considering customer collateral or ability to repay. Such financial instruments are recorded when they are funded.
Premises and Equipment	Premises and Equipment Land is carried at cost. Other premises and equipment are carried at cost, less accumulated depreciation computed on the straight-line method over the estimated useful lives of the assets. In general, estimated lives for buildings are up to 40 years, furniture and equipment useful lives range from five three
Goodwill and Intangible Assets	Goodwill and Intangible Assets Goodwill represents the excess of the cost of businesses acquired over the fair value of the net assets acquired. Goodwill is assigned to reporting units and tested for impairment at least annually, or on an interim basis if an event occurs or circumstances change that would more likely than not reduce the fair value of the reporting unit below its carrying value.
Cash Value of Bank Owned Life Insurance	Cash Value of Bank Owned Life Insurance The Company has purchased life insurance policies on certain officers. The life insurance is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement.
Other Real Estate	Other Real Estate
Income Taxes	Income Taxes The provision for income taxes is based upon income for financial statement purposes, adjusted for nontaxable income and nondeductible expenses. Deferred income taxes have been provided when different accounting methods have been used in determining income for income tax purposes and for financial reporting purposes. Deferred tax assets and liabilities are recognized based on future tax consequences attributable to differences arising from the financial statement carrying values of assets and liabilities and their tax basis. The differences relate primarily to depreciable assets (use of different depreciation methods for financial statement and income tax purposes) and allowance for loan losses (use of the allowance method for financial statement purposes and the direct write-off method for tax purposes). In the event of changes in the tax laws, deferred tax assets and liabilities are adjusted in the period of the enactment of those changes, with effects included in the income tax provision. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized. The Company and its subsidiary file a consolidated federal income tax return. The subsidiary pays its proportional share of federal income taxes to the Company based on its taxable income. The Company’s federal and state income tax returns for tax years 2020, 2019, 2018 and 2017 are subject to examination by the Internal Revenue Service (IRS) and the Georgia Department of Revenue, generally for three years after filing. The Company believes that its income tax filing positions taken or expected to be taken on its tax returns will more likely than not be sustained upon audit by the taxing authorities and does not anticipate any adjustments that will result in a material adverse impact on the Company’s financial condition, results of operations, or cash flow. Therefore, no reserves for uncertain income tax positions have been recorded.
Earnings per Share	Earnings per Share
Comprehensive Income	Comprehensive Income Accounting principles generally require that recognized revenue, expenses, gains and losses be included in net income. Certain changes in assets and liabilities, such as unrealized gains and losses on securities available for sale, represent equity changes from economic events of the period other than transactions with owners. Such items are considered components of other comprehensive income (loss). Accounting standards codification requires the presentation in the consolidated financial statements of net income and all items of other comprehensive income (loss) as total comprehensive income (loss).
Fair Value Measures	Fair Value Measures Fair values of assets and liabilities are estimated using relevant market information and other assumptions, as more fully disclosed in a separate note. Fair value estimates involve uncertainties and matters of significant judgment regarding interest rates, credit risk, prepayments, and other factors, especially in the absence of broad markets for particular items. Changes in assumptions or in market conditions could significantly affect these estimates.
Operating Segments	Operating Segments The Company has three reportable segments, the Banking Division, the Retail Mortgage Division and the Small Business Specialty Lending Division. The Banking Division derives its revenues from the delivery of full service financial services to include commercial loans, consumer loans and deposit accounts. The Retail Mortgage Division derives its revenues from the origination, sales and servicing of one-to-four family residential mortgage loans. The Small Business Specialty Lending Division derives its revenues from origination, sales and servicing of SBA and USDA government guaranteed loans. The Banking, Retail Mortgage and Small Business Specialty Lending Divisions are managed as separate business units because of the different products and services they provide. The Company evaluates performance and allocates resources based on profit or loss from operations. There are no material intersegment sales or transfers.
Reclassifications	Reclassifications Certain amounts, previously reported, have been reclassified to state all periods on a comparable basis and had no effect on stockholders’ equity or net income.
Accounting Standards Updates Pending Adoption	Accounting Standards Updates Pending Adoption In March 2020, the FASB issued updated guidance codified within ASU-2020-04, "Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting," which provide 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. In response to the risk of cessation of the London Interbank Offered Rate ("LIBOR"), regulators in several jurisdictions around the world have undertaken reference rate reform initiatives to identify alternative reference rates that are more observable, or transaction based and less susceptible to manipulation. As of December 31, 2020, the Company had $24.2 million of subordinated debentures with rates tied to LIBOR and is currently evaluating the impact of the amended guidance and has not yet determined the effect of the standard on its ongoing financial reporting. 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 Company does not expect the new guidance to have a material impact on the 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 Company does not expect the new guidance to have a material impact on the consolidated financial statements. 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. The Company is currently assessing the impact of the adoption of this ASU on its consolidated financial statements. In November 2019, the ASU 2019-10 was issued which delayed the effective date of CECL for smaller reporting companies. The new effective date is for fiscal years beginning after December 15, 2022.
Fair Value Measurement	Cash and short-term investments - For cash, due from banks, bank-owned deposits and federal funds sold, the carrying amount is a reasonable estimate of fair value and is classified Level 1. Investment securities - Fair values for investment securities are based on quoted market prices where available and classified as Level 1. If quoted market prices are not available, estimated fair values are based on quoted market prices of comparable instruments and classified as Level 2. If a comparable is not available, the investment securities are classified as Level 3. Other investments at cost - The fair value of other bank stock approximates carrying value and is classified as Level 1. Loans held for sale – The fair value of loans held for sale is determined on outstanding commitments from third party investors in the secondary markets and is classified within Level 2 of the valuation hierarchy. Loans - The fair value of fixed rate loans is estimated by discounting the future cash flows using the current rates at which similar loans would be made to borrowers with similar credit ratings. For variable rate loans, the carrying amount is a reasonable estimate of fair value. Most loans are classified as Level 2, but impaired loans with a related allowance are classified as Level 3. Deposit liabilities - The fair value of demand deposits, savings accounts and certain money market deposits is the amount payable on demand at the reporting date and is classified as Level 1. The fair value of fixed maturity certificates of deposit is estimated by discounting the future cash flows using the rates currently offered for deposits of similar remaining maturities and is classified as Level 2. Federal Home Loan Bank advances – The fair value of Federal Home Loan Bank advances is estimated by discounting the future cash flows using the current rates at which similar advances would be obtained. Federal Home Loan Bank advances are classified as Level 2. Paycheck Protection Liquidity Facility – The fair value of Paycheck Protection Liquidity Facility is estimated by discounting the future cash flows using the current rates at which similar advances would be obtained. Paycheck Protection Liquidity Facility are classified as Level 2. Other borrowings – The fair value of other borrowings is calculated by discounting contractual cash flows using an estimated interest rate based on current rates available to the Company for debt of similar remaining maturities and collateral terms. Other borrowings is classified as Level 2 due to their expected maturities.
