Notes to Financial Statements
Significant Accounting Policies [Text Block]	( 1 Summary of Significant Accounting Policies Principles of Consolidation Colony Bankcorp, Inc. (the Company) is a bank holding company located in Fitzgerald, Georgia. The consolidated financial statements include the accounts of Colony Bankcorp, Inc. and its wholly-owned subsidiary, Colony Bank, Fitzgerald, Georgia. All significant intercompany accounts have been eliminated in consolidation. The accounting and reporting policies of Colony Bankcorp, Inc. conform to generally accepted accounting principles and practices utilized in the commercial banking industry. Nature of Operations The Company 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. Colony 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, Statesboro, Sylvester, 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 losses 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 and note disclosures have been reclassified to conform to statement presentations selected for 2017. no 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, particularly with the current economic downturn in the real estate market. At December 31, 2017, 87.1 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 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 The 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 required for every federally insured institution that utilizes its services. FHLB stock is considered restricted, as defined in the accounting standards. The FHLB stock is reported in the consolidated financial statements at cost. Dividend income is recognized when earned. 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 payments have not When management believes there is sufficient doubt as to the collectibility 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 six may A llowance 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 uncollectibility of 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 collectibility 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 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 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 to obtain an external third may third may 10 may 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. Other 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 an independent 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, federal funds sold and securities purchased under agreement to resell. 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 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.

The consolidated financial statements include the accounts of Colony Bankcorp, Inc. and its wholly-owned subsidiary, Colony Bank, Fitzgerald, Georgia. All significant intercompany accounts have been eliminated in consolidation. The accounting and reporting policies of Colony Bankcorp, Inc. conform to generally accepted accounting principles and practices utilized in the commercial banking industry.
Nature of Operations [Policy Text Block]	Nature of Operations The Company 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.

Lending and investing activities are funded primarily by deposits gathered through its retail banking office network.
Use of Estimates, Policy [Policy Text Block]	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 losses and the valuation of real estate acquired in connection with foreclosures or in satisfaction of loans.
Reclassification, Policy [Policy Text Block]	Reclassifications In certain instances, amounts reported in prior years’ consolidated financial statements and note disclosures have been reclassified to conform to statement presentations selected for 2017. no
Concentration Risk, Credit Risk, Policy [Policy Text Block]	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, particularly with the current economic downturn in the real estate market. At December 31, 2017, 87.1 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
Investment, Policy [Policy Text Block]	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 The 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
Investment in Federal Home Bank Stock [Policy Text Block]	Federal Home Loan Bank Stock Investment in stock of a Federal Home Loan Bank (FHLB) is required for every federally insured institution that utilizes its services. FHLB stock is considered restricted, as defined in the accounting standards. The FHLB stock is reported in the consolidated financial statements at cost. Dividend income is recognized when earned.
Policy Loans Receivable, Policy [Policy Text Block]	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 payments have not When management believes there is sufficient doubt as to the collectibility of principal or interest on any loan or generally when loans are 90 no

Loans and Leases Receivable, Allowance for Loan Losses Policy [Policy Text Block]	A llowance 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 uncollectibility of 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 collectibility 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 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 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 to obtain an external third may third may 10 may 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
Property, Plant and Equipment, Policy [Policy Text Block]	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, Finite-Lived, Policy [Policy Text Block]	Other Intangible Assets Intangible assets consist of core deposit intangibles acquired in connection with a business combination.

Cash flows from demand deposits, interest-bearing checking accounts, savings accounts, loans and certificates of deposit are reported net.
Advertising Costs, Policy [Policy Text Block]	Advertising Costs The Company expenses the cost of advertising in the periods in which those costs are incurred.
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 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 not The Company ’s federal and state income tax returns for tax years 2017, 2016, 2015 2014 three Positions taken in the Company’s tax returns may not 50 may first
Real Estate Owned, Valuation Allowance, Policy [Policy Text Block]	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.
Bank Owned Life Insurance [Policy Text Block]	Bank-Owned Life Insurance The Company has purchased life insurance on the lives of certain key members of management and directors.

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).
