Significant Accounting Policies [Text Block]	( 1 ) Summary of Significant Accounting Policies Presentation Colony Bankcorp, Inc. (the Company) is a bank holding company located in Fitzgerald, Georgia. The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary, Colony Bank, Fitzgerald, Georgia (the Bank). All significant intercompany accounts have been eliminated in consolidation. The accounting and reporting policies of the Company conform to generally accepted accounting principles and practices utilized in the commercial banking industry. All dollars in notes to consolidated financial statements are rounded to the nearest thousand , except for per share amounts. The consolidated financial statements in this report are unaudited, except for the December 31, 201 6 nine September 30, 2017 not may Nature of Operations The Bank provides a full range of retail and commercial banking services for consumers and small- to medium-size businesses located primarily in central, south and coastal Georgia. The Bank is headquartered in Fitzgerald, Georgia with banking offices in Albany, Ashburn, Broxton, Centerville, Columbus, Cordele, Douglas, Eastman, Fitzgerald, Leesburg, Moultrie, Quitman, Rochelle, Savannah, Soperton, Sylvester, Statesboro, Thomaston, Tifton, Valdosta and Warner Robins. Lending and investing activities are funded primarily by deposits gathered through its retail banking office network. Use of Estimates In preparing the financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the balance sheet date and revenues and expenses for the period. Actual results could differ significantly from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losse s and the valuation of real estate acquired in connection with foreclosures or in satisfaction of loans. Reclassifications In certain instances, amounts reported in prior years ’ consolidated financial statements have been reclassified to conform to statement presentations selected for 2017. not Concentrations of Credit Risk Concentrations of credit risk can exist in relation to individual borrowers or groups of borrowers, certain types of collateral, certain types of industries, or certain geographic regions. The Company has a concentration in real estate loans as well as a geographic concentration that could pose an adverse credit risk . At September 30, 2017, 86 The success of the Company is dependent, to a certain extent, upon the economic conditions in the geographic markets it serves. Adverse changes in the economic conditions in these geographic markets would likely have a material adverse effect on the Company’s results of operations and financial condition. The operating results of the Company depend primarily on its net interest income. Accordingly, operations are subject to risks and uncertainties surrounding the exposure to changes in the interest rate environment. At times, the Company may federal deposit insurance limits. The Company places its cash and cash equivalents with high credit quality financial institutions whose credit ratings are monitored by management to minimize credit risk. Investment Securities The Company classifies its investment securities as trading, available for sale or held to maturity. Securities that are held principally for resale in the near term are classified as trading. Trading securities are carried at fair value, with realized and unrealized gains and losses included in noninterest income. Currently, no not may T he Company evaluates each held to maturity and available for sale security in a loss position for other-than-temporary impairment (OTTI). In estimating other-than-temporary impairment losses, management considers such factors as the length of time and the extent to which the market value has been below cost, the financial condition of the issuer and the Company’s intent to sell and whether it is more likely than not not not not not Federal Home Loan Bank Stock Investment in stock of a Federal Home Loan Bank (FHLB) is Loans Loans that the Company has the ability and intent to hold for the foreseeable future or until maturity are recorded at their principal amount outstanding, net of unearned interest and fees . Loan origination fees, net of certain direct origination costs, are deferred and amortized over the estimated terms of the loans using the straight-line method. Interest income on loans is recognized using the effective interest method. A loan is considered to be delinquent when payment s have not When management believes there is sufficient doubt as to the collect ability of principal or interest on any loan or generally when loans are 90 no Loans Modified in a Troubled Debt Restructuring (TDR) Loans are considered to have been modified in a TDR when , due to a borrower’s financial difficulty, the Company makes certain concessions to the borrower that it would not may 6 may may six not 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 inability to collect a loan balance is confirmed. 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 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 2 3 4 5 6 7 8 9 Loans identified as losses by management, internal loan review and/or regulatory agencies 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 ’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 or by senior members of the Company’s credit administration staff. The decision whether or not third may third may 10 not may 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 Premises and Equipment Premises and equipment are recorded at acquisition cost net of accumulated depreciation. Depreciation is charged to operations over the estimated useful lives of the assets. The estimated useful lives and methods of depreciation are as follows: Description Life in Years Method Banking Premises 15 - 40 Straight-Line and Accelerated Furniture and Equipment 5 - 10 Straight-Line and Accelerated Expenditures for major renewals and betterments are capitalized. Maintenance and repairs are charged to operations as incurred. When property and equipment are retired or sold, the cost and accumulated depreciation are removed from the respective accounts and any gain or loss is reflected in other income or expense. Intangible Assets Intangible assets consist of core deposit intangibles acquired in connection with a business combination. The core deposit intangible is initially recognized based on a valuation performed as of the consummation date. The core deposit intangible is amortized by the straight-line method over the average remaining life of the acquired customer deposits. Transfers of Financial Assets Transfers of financial assets are accounted for as sales, when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when ( 1 2 3 not Statement of Cash Flows For reporting cash flows, cash and cash equivalents include cash on hand, noninterest-bearing amounts due from banks and federal funds sold. Cash flows from demand deposits, interest-bearing checking accounts, savings accounts, loans and certificates of deposit are reported net. Advertising Costs The Company expenses the cost of advertising in the periods in which those costs are incurred. 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 bases. 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 not Positions taken in the Company ’s tax returns may not 50 may first 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 other noninterest expense. Bank-Owned Life Insurance The Company has purchased life insurance on the lives of certain key members of management and directors. The life insurance policies are 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 amounts due that are probable at settlement, if applicable. Increases in the cash surrender value are recorded as other income in the consolidated statements of income. The cash surrender value of the insurance contracts is recorded in other assets on the consolidated balance sheets in the amount of $1 5,823 $15,419 September 30, 2017 December 31, 2016, 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 and are not Off-Balance Sheet Credit Related Financial Instruments In the ordinary course of business, the Company has entered into commitments to extend credit, commercial letters of credit and standby letters of credit.

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 (i) the risk grade assigned to commercial and consumer loans, (ii) the level of classified commercial loans, (iii) net charge-offs, (iv) nonperforming loans, and (v) 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 8. ● Grades 1 2 – Borrowers with these assigned grades range in risk from virtual absence of risk to minimal risk.

The Company has a concentration in real estate loans as well as a geographic concentration that could pose an adverse credit risk . At September 30, 2017, 86 The success of the Company is dependent, to a certain extent, upon the economic conditions in the geographic markets it serves. Adverse changes in the economic conditions in these geographic markets would likely have a material adverse effect on the Company’s results of operations and financial condition.

Loans and Leases Receivable, Allowance for Loan Losses Policy [Policy Text Block]	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 inability to collect a loan balance is confirmed. 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 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 2 3 4 5 6 7 8 9 Loans identified as losses by management, internal loan review and/or regulatory agencies 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 ’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 or by senior members of the Company’s credit administration staff.

Income Tax, Policy [Policy Text Block]	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 bases. 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.
