Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Presentation Colony Bankcorp, Inc. (the “Company”) is a bank holding company located in Fitzgerald, Georgia. The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary, Colony Bank, Fitzgerald, Georgia (the “Bank”). The “Company” or “our,” as used herein, includes Colony Bank, except where the context requires otherwise. In July 2019, a new subsidiary of the Company was incorporated under the name Colony Risk Management, Inc. Colony Risk Management, Inc. is a subsidiary of the Company and is located in Las Vegas, Nevada. It is a captive insurance subsidiary which insures various liability and property damage policies for the Company and its related subsidiaries. Colony Risk Management is regulated by the State of Nevada Division of Insurance. All adjustments consisting of normal recurring accruals which are, in the opinion of management, necessary for fair presentation of the interim consolidated financial statements, have been included and fairly and accurately present the financial position, results of operations and cash flows of the Company. All significant intercompany accounts have been eliminated in consolidation. The accounting and reporting policies of the Company conform to generally accepted accounting principles and practices utilized in the commercial banking industry for interim financial information and Regulation S-X. Accordingly, the accompanying unaudited interim consolidated financial statements do not include all of the information or notes required for complete financial statements. The results of operations for the nine months ended September 30, 2021 are not necessarily indicative of the results which may be expected for the year ending December 31, 2021. These statements should be read in conjunction with the consolidated financial statements and notes thereto in the Company's Annual Report on Form 10-K for the year ended December 31, 2020 (“2020 Form 10-K”). Nature of Operations The Bank provides a full range of retail, commercial and mortgage banking services for consumers and small- to medium-size businesses located primarily in central, south and coastal Georgia. The Bank is headquartered in Fitzgerald, Georgia with banking and mortgage offices in Albany, Ashburn, Athens, Broxton, Centerville, Columbus, Cordele, Douglas, Eastman, Fitzgerald, LaGrange, Leesburg, Macon, Moultrie, Quitman, Rochelle, Savannah, Soperton, Statesboro, Sylvester, Tifton, Valdosta and Warner Robins. Lending and investing activities are funded primarily by deposits gathered through its retail banking office network. Use of Estimates In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the balance sheet date and revenues and expenses for the period. Actual results could differ significantly from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, the valuation of real estate acquired in connection with foreclosures or in satisfaction of loans and fair value of assets acquired and liabilities assumed in a business combination, including goodwill impairment. Reclassifications In certain instances, amounts reported in prior years’ consolidated financial statements have been reclassified to conform to statement presentations selected for 2021. Such reclassifications have not materially affected previously reported stockholders’ equity or net income. Concentrations of Credit Risk Concentrations of credit risk can exist in relation to individual borrowers or groups of borrowers, certain types of collateral, certain types of industries, or certain geographic regions. The Company has a concentration in real estate loans as well as a geographic concentration that could pose an adverse credit risk. At September 30, 2021, approximately 86% of the Company’s loan portfolio was concentrated in loans secured by real estate. A substantial portion of borrowers’ ability to honor their contractual obligations is dependent upon the viability of the real estate economic sector. Management continues to monitor these concentrations and has considered these concentrations in its allowance for loan loss analysis. The success of the Company is dependent, to a certain extent, upon the economic conditions in the geographic markets it serves. Adverse changes in the economic conditions in these geographic markets would likely have a material adverse effect on the Company’s results of operations and financial condition. The operating results of the Company depend primarily on its net interest income. Accordingly, operations are subject to risks and uncertainties surrounding the exposure to changes in the interest rate environment. At times, the Company may have cash and cash equivalents at financial institutions in excess of federal deposit insurance limits. The Company places its cash and cash equivalents with high credit quality financial institutions whose credit ratings are monitored by management to minimize credit risk. Changes in Accounting Principles and Effects of New Accounting Pronouncements ASU 2016-13, Financial Instruments – Credit Losses (Topic 326). This ASU sets forth a “current expected credit loss” (CECL) model which requires the Company to measure all expected credit losses for financial instruments held at the reporting date based on historical experience, current conditions and reasonable supported forecasts. This replaces the existing incurred loss model and is applicable to the measurement of credit losses on financial assets measured at amortized cost and applies to some off-balance sheet credit exposures. This ASU is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. On October 16, 2019, the Financial Accounting Standards Board ("FASB") voted to extend the delay of the effective date of this ASU for smaller reporting companies, such as the Company, until fiscal years beginning after December 15, 2022. The Company is currently assessing the impact of the adoption of this ASU on its consolidated financial statements. In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740) : Simplifying the Accounting for Income Taxes. This update removes several exceptions related to intraperiod tax allocation when there is a loss from continuing operations and income from other items, foreign subsidiaries becoming equity method investments and vice versa, and calculating income taxes in an interim period when a year-to-date loss exceeds the anticipated loss for the year. The guidance also amends requirements related to franchise tax that is partially based on income, a step up in the tax basis of goodwill, allocation of consolidated tax expense to a legal entity not subject to tax in its separate financial statements, the effects of enacted changes in tax laws and other minor codification improvements regarding employee stock ownership plans and investments in qualified affordable housing projects. For public entities, this guidance is effective for fiscal years beginning after December 15, 2020. The Company adopted this standard as of January 1, 2021. The adoption of this standard did not have a material impact on the consolidated financial statements. In January 2020, the FASB issued ASU No. 2020-01, Investments—Equity Securities (Topic 321), Investments—Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815)—Clarifying the Interactions between Topic 321, Topic 323, and Topic 815 (a consensus of the Emerging Issues Task Force) . This update clarifies whether an entity should consider observable transactions that require it to either apply or discontinue the equity method of accounting for the purposes of applying the measurement alternative and how to account for certain forward contracts and purchased options to purchase securities. For public entities, this guidance is effective for fiscal years beginning after December 15, 2020. The Company adopted this standard as of January 1, 2021. The adoption of this standard did not have a material impact on the consolidated financial statements. In March 2020, the FASB issued ASU No. 2020-04, Reference Reform (Topic 848) Facilitation of the Effects of Reference Rate Reform on Financial Reporting ("ASU 2020-04"). ASU 2020-04 provides optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. The amendments are effective for the Company as of March 12, 2020 through December 31, 2022. The provisions of ASU 2020-04 did not have a material impact on the consolidated financial statements. Operating, Accounting and Reporting Considerations Related to COVID-19 The COVID-19 pandemic has negatively impacted the global economy, including the Company’s primary metropolitan markets. In response to this crisis, the Coronavirus Aid, Relief, and Economic Security (“CARES”) Act was passed by Congress and signed into law on March 27, 2020. The CARES Act initially provided approximately $2.2 trillion to fight the COVID-19 pandemic and related variants and stimulate the economy by supporting individuals and businesses through loans, grants, tax changes, and other types of relief. The CARES Act was later amended to provide additional funding and to make additional changes to the programs it implemented. Some of the provisions applicable to the Company include, but are not limited to: • Accounting for Loan Modifications - The CARES Act provided 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. The Consolidated Appropriations Act (“CAA”), signed into law on December 27, 2020, extended the applicable period to include modification to loans held by financial institutions executed between March 1, 2020 and the earlier of (i) January 1, 2022, or (ii) 60 days after the date of termination of the COVID-19 national emergency. • 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. The CAA provided several amendments to the PPP, including additional funding for first and second draws of PPP loans up to March 31, 2021. On March 30, 2021, the PPP Extension Act of 2021 was signed into law, which extended the program to May 31, 2021. Also in response to the COVID-19 pandemic and related variants, the Board of Governors of the Federal Reserve System (“FRB”), the Federal Deposit Insurance Corporation (“FDIC”), the National Credit Union Administration (“NCUA”), the Office of the Comptroller of the Currency (“OCC”), and the Consumer Financial Protection Bureau (“CFPB”), in consultation with the state financial regulators (collectively, the “agencies”) issued a joint interagency statement (issued March 22, 2020; revised statement issued April 7, 2020). Some of the provisions applicable to the Company include, but are not limited to: • Accounting for Loan Modifications - Loan modifications that do not meet the conditions of the CARES Act may still qualify as a modification that does not need to be accounted for as a TDR. The agencies confirmed with FASB staff that short-term modifications made on a good faith basis in response to COVID-19 pandemic and related variants to borrowers who were current prior to any relief are not TDRs. This includes short-term (e.g., three months) modifications such as payment deferrals, fee waivers, extensions of repayment terms, or insignificant delays in payment, as long as such modifications are (1) related to COVID-19; (2) executed on a loan that was not more than 30 days past due as of December 31, 2019; and (3) executed between March 1, 2020, and the earlier of (a) 60 days after the date of termination of the national emergency declaration or (b) December 31, 2021, as extended by the CAA. • Past Due Reporting - With regard to loans not otherwise reportable as past due, financial institutions are not expected to designate loans with deferrals granted due to COVID-19 as past due because of the deferral. A loan’s payment date is governed by the due date stipulated in the legal agreement. If a financial institution agrees to a payment deferral, these loans would not be considered past due reporting during the period of the deferral. • Nonaccrual Status and Charge-offs - During short-term COVID-19 modifications, these loans generally should not be reported as nonaccrual or as classified. As such, beginning in late March 2020, the Company provided relief programs consisting primarily of 90-day payment deferral relief of principal and interest to borrowers negatively impacted by COVID-19 and has accounted for these loan modifications in accordance with ASC 310-40. In addition, the Company also provided principal only payment deferral relief to borrowers of which interest income has been recognized during the deferment period on these interest-only loans.

Business Combination and Asset Acquisition [Abstract]
Business Acquisitions	Business Acquisitions Acquisition of SouthCrest Financial Group On August 1, 2021, the Company completed its acquisition of SouthCrest Financial Group, Inc. (“SouthCrest”), a bank holding company headquartered in Atlanta, Georgia. Upon consummation of the acquisition, SouthCrest was merged with and into the Company, with Colony Bankcorp, Inc. as the surviving entity in the merger. Immediately following the holding company merger, SouthCrest’s wholly owned bank subsidiary, SouthCrest Bank, N.A. was also merged with and into the Bank. The acquisition expanded the Company’s market presence, as SouthCrest Bank, N.A. had eight full-service banking locations, one in Cedartown, Chickamauga, Cumming, Fayetteville, Luthersville, Manchester, Rockmart and Thomaston, Georgia. Under the terms of the Agreement and Plan of Merger, each SouthCrest shareholder had the option to receive either $10.45 in cash or 0.7318 shares of the Company’s common stock in exchange for each share of SouthCrest common stock. As a result, the Company issued 3,987,898 common shares at a fair value of $71.4 million and paid $21.6 million in cash to the former shareholders of SouthCrest as merger consideration. The merger was effected by the issuance of shares of the Company’s common stock along with cash consideration to shareholders of SouthCrest. The assets and liabilities of SouthCrest 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 approximately $35.0 million was recorded as part of the SouthCrest acquisition and is not expected to be deductible for income tax purposes. In periods following the merger, the financial statements of the combined entity will include the results attributable to SouthCrest beginning on the date the merger was completed. In the three and nine month period ended September 30, 2021, the revenues attributable to SouthCrest were approximately $3.0 million. In the three and nine month period ended September 30, 2021, the net income attributable to SouthCrest was approximately $2.3 million. The supplemental consolidated pro-forma impact to 2020 revenues if the merger had occurred on January 1, 2020 would have been $29.5 million and $82.6 million for the three and nine month period ended September 30, 2020, respectively. The supplemental consolidated pro-forma impact to 2020 net income if the merger had occurred on January 1, 2020 would have been $5.5 million and $5.8 million for the three and nine month period ended September 30, 2020, respectively. The supplemental consolidated pro-forma impact to 2021 revenues if the merger had occurred on January 1, 2020 would have been $28.9 million and $90.9 million for the three and nine month period ended September 30, 2021, respectively. The supplemental consolidated pro-forma impact to 2021 net income if the merger had occurred on January 1, 2020 would have been $4.3 million and $16.6 million for the three and nine month period ended September 30, 2021, respectively. While certain adjustments were made for the estimated impact of certain fair value adjustments, they are not indicative of what would have occurred had the merger taken place on the indicated date nor are they intended to represent or be indicative of future results of operations. In particular, no adjustments have been made to eliminate the amount of SouthCrest’s provision for credit losses or any adjustments to estimate any additional income that would have been recorded as a result of fair value adjustments for the first nine months of 2020 that may have occurred had the acquired loans been recorded at fair value as of the beginning of 2020. In addition, there are no adjustments to reflect any expenses that potentially could have been reduced for the first nine months of 2020 had the merger occurred on January 1, 2020. The following table presents the assets acquired and liabilities assumed of SouthCrest as of August 1, 2021, 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. The Company continues its evaluation of the facts and circumstances available as of August 1, 2021, to assign fair values to assets acquired and liabilities assumed, which could result in further adjustments to the fair values presented below.

The sale of investment securities for the nine months ended September 30, 2021 and 2020 resulted in gross realized gains of $209,000 and $1,200,000 and losses of $72,000 and $191,000, respectively. Investment securities having a carrying value approximating $203.9 million and $126.5 million were pledged to secure public deposits and for other purposes as of September 30, 2021 and December 31, 2020, respectively. Information pertaining to securities with gross unrealized losses at September 30, 2021 and December 31, 2020 aggregated by investment category and length of time that individual securities have been in a continuous loss position, follows: Less Than 12 Months 12 Months or Greater Total (dollars in thousands) Fair Gross Fair Gross Fair Gross September 30, 2021 U.S. Treasury $ 42,382 $ (652) $ — $ — $ 42,382 $ (652) U.S. agency 8,473 (165) — — 8,473 (165) State, county & municipal securities 158,260 (3,446) 2,476 (74) 160,736 (3,520) Corporate debt securities 18,711 (163) — — 18,711 (163) Mortgage-backed securities 299,693 (4,520) 13,837 (230) 313,530 (4,750) $ 527,519 $ (8,946) $ 16,313 $ (304) $ 543,832 $ (9,250) December 31, 2020 State, county & municipal securities $ 8,282 $ (65) $ — $ — $ 8,282 $ (65) Corporate debt securities 999 (1) — — 999 (1) Mortgage-backed securities 28,835 (77) 3,949 (271) 32,784 (348) $ 38,116 $ (143) $ 3,949 $ (271) $ 42,065 $ (414) Management evaluates securities for other-than-temporary impairment at least on a quarterly basis, and more frequently when economic or market concerns warrant such evaluation. 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.

Loans	Loans The following table presents the composition of loans segregated by legacy and purchased loans and by class of loans, as of September 30, 2021 and December 31, 2020. Purchased loans are defined as loans that were acquired in bank acquisitions.

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. 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 an eight category risk grading system to assign a risk grade to each loan in the portfolio. The following is a description of the general characteristics of the grades: • 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, of which the Company has no loans with these assigned grades at September 30, 2021. 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 table presents the loan portfolio, excluding purchased loans, by credit quality indicator (risk grade) as of September 30, 2021 and 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.

Those loans with a risk grade of 1, 2, 3 or 4 have been combined in the pass column for presentation purposes. For the period ending September 30, 2021, the Company did not have any loans classified as “doubtful” or a “loss”.

Loan risk grades are subject to review at various times throughout the year as part of the Company’s ongoing loan review process. Loans with an assigned risk grade of six 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 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 guidelines. Loans may be placed on nonaccrual status regardless of whether or not such loans are considered past due.

Troubled Debt Restructurings The restructuring of a loan is considered a troubled debt restructuring ("TDRs") if both the borrower is experiencing financial difficulties and the Company has granted a concession to the terms of the loan. Concessions may include interest rate reductions to below market interest rates, principal forgiveness, restructuring amortization schedules and other actions intended to minimize potential losses. As discussed in Note 1 of the Notes to Consolidated Financial Statements for the year ended December 31, 2020, which are included in the Company’s 2020 Form 10-K, 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 September 30, 2021. The Company had one construction, land and land development loan restructured during the nine month period ended September 30, 2021 with outstanding principal balance of $511,000. 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.

Leases

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. 2016-02 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 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 September 30, 2021 December 31, 2020 Assets Operating lease right-of-use assets Other assets $ 773 $ 511 Liabilities Operating lease liabilities Other liabilities 787 517 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, 2020, the rate for the remaining lease term as of January 1, 2020 was used. Operating lease cost was $10,000, $64,000, $108,000, and $180,000 for the three and nine months ended September 30, 2021 and 2020, respectively. As of September 30, 2021, the weighted average remaining lease term was 1.65 years and the weighted average discount rate was 0.52%. The following table represents the future maturities of the operating lease liabilities and other lease information as of September 30, 2021.

As collateral on the outstanding FHLB advances, the Company has provided a blanket lien on its portfolio of qualifying residential first mortgage loans, commercial loans, multifamily loans and HELOC loans. At September 30, 2021, the lendable collateral of those loans pledged is $136.2 million. At September 30, 2021, the Company had remaining credit availability from the FHLB of $385.4 million. The Company may be required to pledge additional qualifying collateral in order to utilize the full amount of the remaining credit line. On May 1, 2019, the Company entered into two borrowing arrangements with a correspondent bank for $10.0 million each. The term note is secured by the Bank’s stock, expiring on May 1, 2024, and bears a fixed interest rate of 4.70%. The line of credit is also secured by the Bank’s stock, expiring on July 30, 2022, and bears a variable interest rate of Wall Street Journal Prime minus 0.40%.The proceeds were used for the acquisition of LBC Bancshares, Inc. and its subsidiary, Calumet Bank. As of September 30, 2021, the outstanding balance of the term note and the line of credit totaled $7.5 million and $5.3 million, respectively. On April 20, 2020 the Company completed a Paycheck Protection Program Liquidity Facility ("PPPLF") credit arrangement with the Federal Reserve. This line of credit was secured by PPP loans and bore a fixed interest rate of 0.35% with a maturity date equal to the maturity date of the related PPP loans, with the PPP loans maturing either two The Company's debentures issued in connection with trust preferred securities are recorded as subordinated debentures on the consolidated balance sheets, but, subject to certain limitations, qualify as Tier 1 capital for regulatory capital purposes. At September 30, 2021 and December 31, 2020, $24.2 million of debentures underlying trust preferred securities were outstanding. The proceeds from the offerings were used to fund certain acquisitions, pay off holding company debt and inject capital into the bank subsidiary. The debentures underlying the trust preferred securities require quarterly interest payments. The aggregate stated maturities of other borrowed money at September 30, 2021 are as follows: (dollars in thousands) Year Amount 2021 $ — 2022 5,313 2023 3,000 2024 7,500 2025 4,500 2026 and After 69,229 Fair Value adjustment for FHLB borrowings acquired from SouthCrest (899) $ 88,643 The Company also has available federal funds lines of credit with various financial institutions totaling $53.0 million, none of which were outstanding at September 30, 2021. The Company has the ability to borrow funds from the Federal Reserve Bank (“FRB”) of Atlanta utilizing the discount window. The discount window is an instrument of monetary policy that allows eligible institutions to borrow money from the FRB on a short-term basis to meet temporary liquidity shortages caused by internal or external disruptions. At September 30, 2021, the Company had borrowing capacity available under this arrangement, with no outstanding balances. The Company would be required to pledge certain available-for-sale investment securities as collateral under this agreement.

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. The Company evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary, upon extension of credit, is based on management’s credit evaluation of the borrower. Collateral held varies, but may include cash or cash equivalents, negotiable instruments, real estate, accounts receivable, inventory, oil, gas and mineral interests, property, plant, and equipment. At September 30, 2021 and December 31, 2020 the following financial instruments were outstanding whose contract amounts represent credit risk: Contract Amount (dollars in thousands) September 30, 2021 December 31, 2020 Loan commitments $ 85,573 $ 198,029 Letters of credit 5,836 3,634 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 the Company and the Bank. As of September 30, 2021, the aggregate liabilities, if any, arising from such proceedings would not, in the opinion of management, have a material adverse effect on the Company’s consolidated financial position.

Fair Value of Financial Instrum

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments and Fair Value Measurements	Fair Value of Financial Instruments and Fair Value MeasurementsGenerally 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 the Company and the Bank’s 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 as 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 Federal Home Loan Bank stock approximates carrying value and is 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. 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 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 2. The fair value of deposits 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 PPPLF is estimated by discounting the future cash flows using the current rates at which similar advances would be obtained. PPPLF 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 as of September 30, 2021 and December 31, 2020 are as follows: Fair Value Measurements (dollars in thousands) Carrying Estimated Level Level Level September 30, 2021 Assets Cash and short-term investments $ 176,997 $ 176,997 $ 176,997 $ — $ — Investment securities available for sale 820,625 820,625 42,382 778,243 — Other investments, at cost 13,977 13,977 — 13,977 — Loans held for sale 26,697 26,697 — 26,697 — Loans, net 1,296,983 1,303,994 — — 1,303,994 Liabilities Deposits 2,195,122 2,195,624 — 2,195,624 — Federal Home Loan Bank advances 51,601 50,528 — 50,528 — Other borrowings 37,042 36,767 — 36,767 — Fair Value Measurements (dollars in thousands) Carrying Estimated Level Level Level 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 — Paycheck Protection Program Liquidity Facility 106,789 106,789 — 106,789 Federal Home Loan Bank advances 22,500 20,817 — 20,817 — Other borrowings 37,792 37,792 — 37,792 — 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: Securities – Where quoted prices are available in an active market, securities are classified within level 1 of the valuation hierarchy. Level 1 inputs include securities that have quoted prices in active markets for identical assets. If quoted market prices are not available, then fair values are estimated by using pricing models, quoted prices of securities with similar characteristics, or discounted cash flow. Examples of such instruments, which would generally be classified within level 2 of the valuation hierarchy, include certain collateralized mortgage and debt obligations and certain high-yield debt securities. In certain cases where there is limited activity or less transparency around inputs to the valuation, securities are classified within level 3 of the valuation hierarchy. When measuring fair value, the valuation techniques available under the market approach, income approach and/or cost approach are used. The Company’s evaluations are based on market data and the Company employs combinations of these approaches for its valuation methods depending on the asset class. 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 Owned – 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% 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 September 30, 2021 and December 31, 2020, 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 September 30, 2021 and December 31, 2020. Those impaired loans and other real estate properties are shown net of the related specific reserves and valuation allowances.

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. Information reported internally for performance assessment follows. The following tables present information reported internally for performance assessment for the three and nine months ended September 30, 2021 and 2020: (dollars in thousands) Bank Mortgage Small Totals Three months ended September 30, 2021 Net Interest Income $ 17,181 $ 138 $ 549 $ 17,868 Provision for Loan Losses 150 — — 150 Noninterest Income 4,340 3,104 1,994 9,438 Noninterest Expenses 16,941 2,765 1,505 21,211 Income Taxes 434 (290) 218 362 Segment Profit $ 3,996 $ 767 $ 820 $ 5,583 Segments Assets at September 30, 2021 $ 2,468,106 $ 21,184 $ 23,291 $ 2,512,581 Full time employees at September 30, 2021 417 53 24 494 (dollars in thousands) Bank Mortgage Small Totals Three months ended September 30, 2020 Net Interest Income $ 13,631 $ 188 $ 29 $ 13,848 Provision for Loan Losses 1,106 — — 1,106 Noninterest Income 4,139 2,612 803 7,554 Noninterest Expenses 12,415 2,410 1,488 16,313 Income Taxes 940 82 (138) 884 Segment Profit (Loss) $ 3,309 $ 308 $ (1,350) $ 3,099 Segments Assets at December 31, 2020 $ 1,709,696 $ 50,266 $ 4,012 $ 1,763,974 Full time employees at September 30, 2020 312 41 15 368 (dollars in thousands) Bank Mortgage Small Totals Nine months ended September 30, 2021 Net Interest Income $ 45,977 $ 429 $ 761 $ 47,167 Provision for Loan Losses 650 — — 650 Noninterest Income 10,409 10,087 4,979 25,475 Noninterest Expenses 41,922 8,445 3,746 54,113 Income Taxes 2,836 124 419 3,379 Segment Profit $ 10,978 $ 1,947 $ 1,575 $ 14,500 (dollars in thousands) Bank Mortgage Small Totals Nine months ended September 30, 2020 Net Interest Income $ 39,727 $ 305 $ 62 $ 40,094 Provision for Loan Losses 5,262 — — 5,262 Noninterest Income 9,960 5,686 1,183 16,829 Noninterest Expenses 34,112 5,302 3,524 42,938 Income Taxes 2,149 137 (479) 1,807 Segment Profit (Loss) $ 8,164 $ 552 $ (1,800) $ 6,916

Regulatory Capital Matters

Regulatory Capital Matters	9 Months Ended

Banking And Thrift Disclosure [Abstract]
Regulatory Capital Matters	Regulatory Capital Matters 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 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 classifications 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 1 capital to risk-weighted assets, and of Tier 1 capital to average assets. As of September 30, 2021, 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 September 30, 2021, 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 events or conditions 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% of risk-weighted assets and increase each subsequent year by 0.625% until reaching its final level of 2.5% on January 1, 2019. The Bank participated 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. All PPPLF advances were repaid in full during the second quarter of 2021. The Board of Governors of the Federal Reserve raised the threshold for determining applicable of the Small Bank Holding Company and Savings and Loan Company Policy Statement in August 2018 from $1 billion to $3 billion in consolidated total assets to provide regulatory burden relief, therefore, the Company is no longer subject to the minimum capital requirements on a consolidated basis. The following table summarizes regulatory capital information as of September 30, 2021 and December 31, 2020 on a consolidated basis and for the subsidiary, as defined. Regulatory capital ratios for September 30, 2021 and December 31, 2020 were calculated in accordance with the Basel III rules.

Accounting Policies [Abstract]
Presentation	Presentation Colony Bankcorp, Inc. (the “Company”) is a bank holding company located in Fitzgerald, Georgia. The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary, Colony Bank, Fitzgerald, Georgia (the “Bank”). The “Company” or “our,” as used herein, includes Colony Bank, except where the context requires otherwise. In July 2019, a new subsidiary of the Company was incorporated under the name Colony Risk Management, Inc. Colony Risk Management, Inc. is a subsidiary of the Company and is located in Las Vegas, Nevada. It is a captive insurance subsidiary which insures various liability and property damage policies for the Company and its related subsidiaries. Colony Risk Management is regulated by the State of Nevada Division of Insurance. All adjustments consisting of normal recurring accruals which are, in the opinion of management, necessary for fair presentation of the interim consolidated financial statements, have been included and fairly and accurately present the financial position, results of operations and cash flows of the Company. All significant intercompany accounts have been eliminated in consolidation. The accounting and reporting policies of the Company conform to generally accepted accounting principles and practices utilized in the commercial banking industry for interim financial information and Regulation S-X. Accordingly, the accompanying unaudited interim consolidated financial statements do not include all of the information or notes required for complete financial statements. The results of operations for the nine months ended September 30, 2021 are not necessarily indicative of the results which may be expected for the year ending December 31, 2021. These statements should be read in conjunction with the consolidated financial statements and notes thereto in the Company's Annual Report on Form 10-K for the year ended December 31, 2020 (“2020 Form 10-K”).
Nature of Operations	Nature of Operations The Bank provides a full range of retail, commercial and mortgage banking services for consumers and small- to medium-size businesses located primarily in central, south and coastal Georgia. The Bank is headquartered in Fitzgerald, Georgia with banking and mortgage offices in Albany, Ashburn, Athens, Broxton, Centerville, Columbus, Cordele, Douglas, Eastman, Fitzgerald, LaGrange, Leesburg, Macon, Moultrie, Quitman, Rochelle, Savannah, Soperton, Statesboro, Sylvester, Tifton, Valdosta and Warner Robins. Lending and investing activities are funded primarily by deposits gathered through its retail banking office network.
Use of Estimates	Use of Estimates In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the balance sheet date and revenues and expenses for the period. Actual results could differ significantly from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, the valuation of real estate acquired in connection with foreclosures or in satisfaction of loans and fair value of assets acquired and liabilities assumed in a business combination, including goodwill impairment.
Reclassifications	Reclassifications In certain instances, amounts reported in prior years’ consolidated financial statements have been reclassified to conform to statement presentations selected for 2021. Such reclassifications have not materially affected previously reported stockholders’ equity or net income.
Concentrations of Credit Risk	Concentrations of Credit Risk 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, 2021, approximately 86% of the Company’s loan portfolio was concentrated in loans secured by real estate. A substantial portion of borrowers’ ability to honor their contractual obligations is dependent upon the viability of the real estate economic sector. Management continues to monitor these concentrations and has considered these concentrations in its allowance for loan loss analysis. The success of the Company is dependent, to a certain extent, upon the economic conditions in the geographic markets it serves. Adverse changes in the economic conditions in these geographic markets would likely have a material adverse effect on the Company’s results of operations and financial condition. The operating results of the Company depend primarily on its net interest income. Accordingly, operations are subject to risks and uncertainties surrounding the exposure to changes in the interest rate environment. At times, the Company may have cash and cash equivalents at financial institutions in excess of federal deposit insurance limits. The Company places its cash and cash equivalents with high credit quality financial institutions whose credit ratings are monitored by management to minimize credit risk.
Changes in Accounting Principles and effects of New Accounting Pronouncements	Changes in Accounting Principles and Effects of New Accounting Pronouncements ASU 2016-13, Financial Instruments – Credit Losses (Topic 326). This ASU sets forth a “current expected credit loss” (CECL) model which requires the Company to measure all expected credit losses for financial instruments held at the reporting date based on historical experience, current conditions and reasonable supported forecasts. This replaces the existing incurred loss model and is applicable to the measurement of credit losses on financial assets measured at amortized cost and applies to some off-balance sheet credit exposures. This ASU is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. On October 16, 2019, the Financial Accounting Standards Board ("FASB") voted to extend the delay of the effective date of this ASU for smaller reporting companies, such as the Company, until fiscal years beginning after December 15, 2022. The Company is currently assessing the impact of the adoption of this ASU on its consolidated financial statements. In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740) : Simplifying the Accounting for Income Taxes. This update removes several exceptions related to intraperiod tax allocation when there is a loss from continuing operations and income from other items, foreign subsidiaries becoming equity method investments and vice versa, and calculating income taxes in an interim period when a year-to-date loss exceeds the anticipated loss for the year. The guidance also amends requirements related to franchise tax that is partially based on income, a step up in the tax basis of goodwill, allocation of consolidated tax expense to a legal entity not subject to tax in its separate financial statements, the effects of enacted changes in tax laws and other minor codification improvements regarding employee stock ownership plans and investments in qualified affordable housing projects. For public entities, this guidance is effective for fiscal years beginning after December 15, 2020. The Company adopted this standard as of January 1, 2021. The adoption of this standard did not have a material impact on the consolidated financial statements. In January 2020, the FASB issued ASU No. 2020-01, Investments—Equity Securities (Topic 321), Investments—Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815)—Clarifying the Interactions between Topic 321, Topic 323, and Topic 815 (a consensus of the Emerging Issues Task Force) . This update clarifies whether an entity should consider observable transactions that require it to either apply or discontinue the equity method of accounting for the purposes of applying the measurement alternative and how to account for certain forward contracts and purchased options to purchase securities. For public entities, this guidance is effective for fiscal years beginning after December 15, 2020. The Company adopted this standard as of January 1, 2021. The adoption of this standard did not have a material impact on the consolidated financial statements. In March 2020, the FASB issued ASU No. 2020-04, Reference Reform (Topic 848) Facilitation of the Effects of Reference Rate Reform on Financial Reporting ("ASU 2020-04"). ASU 2020-04 provides optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. The amendments are effective for the Company as of March 12, 2020 through December 31, 2022. The provisions of ASU 2020-04 did not have a material impact on the consolidated financial statements.
Earnings Per Share	Basic earnings per share is computed by dividing net income available to common stockholders by the weighted average number of common shares outstanding during each period. Diluted earnings per share reflects the potential dilution of restricted stock.
Fair Value of Financial Instruments and Fair Value Measurements	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 as 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 Federal Home Loan Bank stock approximates carrying value and is 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. 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 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 2. The fair value of deposits 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 PPPLF is estimated by discounting the future cash flows using the current rates at which similar advances would be obtained. PPPLF 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.
