Summary of Significant Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 1 - Summary of Significant Accounting Policies In the opinion of management, the unaudited condensed consolidated financial statements include all adjustments (which consist of normal recurring adjustments) necessary, to present fairly the condensed consolidated financial position as of March 31, 2021 and the results of operations, other comprehensive income, changes in shareholders’ equity, and cash flows for the three months ended March 31, 2021 and 2020. In accordance with accounting principles generally accepted in the United States of America for interim financial information, these statements do not include certain information and footnote disclosures required by accounting principles generally accepted in the United States of America for complete annual financial statements. The results of operations and cash flows for the three months ended March 31, 2021 and 2020 are not necessarily indicative of the results to be expected for the full year. The condensed consolidated balance sheet as of December 31, 2020 has been derived from the audited consolidated financial statements of Community Trust Bancorp, Inc. (“CTBI”) for that period. For further information, refer to the consolidated financial statements and footnotes thereto for the year ended December 31, 2020, included in our annual report on Form 10-K. Principles of Consolidation – New Accounting Standards ➢ Simplifying the Accounting for Income Taxes Income Taxes (Topic 740), Simplifying the Accounting for Income Taxes 1. Exception to the incremental approach for intra period tax allocation when there is a loss from continuing operations and income or a gain from other items (for example, discontinued operations or other comprehensive income); 2. Exception to the requirement to recognize a deferred tax liability for equity method investments when a foreign subsidiary becomes an equity method investment; 3. Exception to the ability not to recognize a deferred tax liability for a foreign subsidiary when a foreign equity method investment becomes a subsidiary; and 4. Exception to the general methodology for calculating income taxes in an interim period when a year-to-date loss exceeds the anticipated loss for the year. The amendments in this ASU also simplify the accounting for income taxes by doing the following: 1. Requiring that an entity recognize a franchise tax (or similar tax) that is partially based on income as an income-based tax and account for any incremental amount incurred as a non-income-based tax; 2. Requiring that an entity evaluate when a step up in the tax basis of goodwill should be considered part of the business combination in which the book goodwill was originally recognized and when it should be considered a separate transaction; 3. Specifying that an entity is not required to allocate the consolidated amount of current and deferred tax expense to a legal entity that is not subject to tax in its separate financial statements. However, an entity may elect to do so (on an entity-by-entity basis) for a legal entity that is both not subject to tax and disregarded by the taxing authority; 4. Requiring that an entity reflect the effect of an enacted change in tax laws or rates in the annual effective tax rate computation in the interim period that includes the enactment date; and 5. Making minor codification improvements for income taxes related to employee stock ownership plans and investments in qualified affordable housing projects accounted for using the equity method. For public business entities, the amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. CTBI adopted this ASU effective January 1, 2021 with no significant impact to our consolidated financial statements. ➢ Clarifying the Interactions between Topic 321 Topic 323 and Topic 815 a consensus of the FASB Emerging Task Force Investments—Equity Securities (Topic 321), Investments—Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815) Financial Instruments ➢ Facilitation of the Effects of Reference Rate Reform on Financial Reporting In response to concerns about structural risks of interbank offered rates, and, particularly, the risk of cessation of the London Interbank Offered Rate (LIBOR), regulators around the world have undertaken reference rate reform initiatives to identify alternative reference rates that are more observable or transaction-based and less susceptible to manipulation. The amendments in this ASU provide optional guidance for a limited time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting and provide optional expedients and exceptions for applying generally accepted accounting principles to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. This ASU applies only to contracts and hedging relationships that reference LIBOR or another reference rate expected to be discontinued due to reference rate reform. The expedients and exceptions provided by the amendments do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022. Critical Accounting Policies and Estimates The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires the appropriate application of certain accounting policies, many of which require us to make estimates and assumptions about future events and their impact on amounts reported in our consolidated financial statements and related notes. Since future events and their impact cannot be determined with certainty, the actual results will inevitably differ from our estimates. Such differences could be material to the consolidated financial statements. We believe the application of accounting policies and the estimates required therein are reasonable. These accounting policies and estimates are constantly reevaluated, and adjustments are made when facts and circumstances dictate a change. Historically, we have found our application of accounting policies to be appropriate, and actual results have not differed materially from those determined using necessary estimates. Our accounting policies are described in Note 1 to the condensed consolidated financial statements. We have identified the following critical accounting policies: Investments Investments – Debt Securities a. Trading securities . . b. Available-for-sale securities. Investments not classified as trading securities (nor as held-to-maturity securities) shall be classified as available-for-sale securities. We do not have any securities that are classified as trading securities. Available-for-sale securities are reported at fair value, with unrealized gains and losses included as a separate component of shareholders’ equity, net of tax. If declines in fair value are other than temporary, the carrying value of the securities is written down to fair value as a realized loss with a charge to income for the portion attributable to credit losses and a charge to other comprehensive income for the portion that is not credit related. Gains or losses on disposition of debt securities are computed by specific identification for those securities. Interest and dividend income, adjusted by amortization of purchase premium or discount, is included in earnings. An allowance is recognized for credit losses relative to available-for-sale securities rather than as a reduction in the cost basis of the security. Subsequent improvements in credit quality or reductions in estimated credit losses are recognized immediately as a reversal of the previously recorded allowance, which aligns the income statement recognition of credit losses with the reporting period in which changes occur. Held-to-maturity (“HTM”) securities are subject to an allowance for lifetime expected credit losses, determined by adjusting historical loss information for current conditions and reasonable and supportable forecasts. The forward-looking evaluation of lifetime expected losses will be performed on a pooled basis for debt securities that share similar risk characteristics. These allowances for expected losses must be made by the holder of the HTM debt security when the security is purchased. At March 31, 2021, CTBI held no securities designated as held-to-maturity. CTBI accounts for equity securities in accordance with Accounting Standards Codification (“ASC”) 321, Investments – Equity Securities Equity securities with a readily determinable fair value are required to be measured at fair value, with changes in fair value recognized through net income. Equity securities without a readily determinable fair value are carried at cost, less any impairment, if any, plus or minus changes resulting from observable price changes for identical or similar investments. As permitted by ASC 321-10-35-2, CTBI can make an irrevocable election to subsequently measure an equity security without a readily determinable fair value, and all identical or similar investments of the same issuer, including future purchases of identical or similar investments of the same issuer, at fair value. CTBI has made this election for its Visa Class B equity securities. The fair value of these securities was determined by a third party service provider using Level 3 inputs as defined in ASC 820, Fair Value Measurement Loans The Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) included an election for banking institutions to not apply the guidance on accounting for troubled debt restructurings to loan modifications, such as extensions or deferrals, related to COVID-19 made between March 1, 2020 and the earlier of (i) December 31, 2020 or (ii) 60 days after the end of the COVID-19 national emergency. The relief can only be applied to modifications for borrowers that were not more than 30 days past due as of December 31, 2019. The ability to exclude COVID-19-related modifications as troubled debt restructurings was extended under the Consolidated Appropriations Act 2021 to the earlier of (i) 60 days after the COVID-19 national emergency and (ii) January 1, 2022. CTBI elected to adopt these provisions of the CARES Act, as extended by the Consolidated Appropriations Act 2021 . Loan origination and commitment fees and certain direct loan origination costs are deferred and the net amount amortized over the estimated life of the related loans, leases, or commitments as a yield adjustment. Allowance for Credit Losses In the event that collection of principal becomes uncertain, CTBI has policies in place to reverse accrued interest in a timely manner. Therefore, CTBI elected ASU 2019-04 which allows that accrued interest would continue to be presented separately and not part of amortized cost on loan. The methodology used by CTBI is developed using the current loan balance, which is then compared to amortized cost balances to analyze the impact. The difference in amortized cost basis versus consideration of loan balances impacts the allowance for credit losses calculation by one basis point We maintain an allowance for credit losses (“ACL”) at a level that is appropriate to cover estimated credit losses on individually evaluated loans, as well as estimated credit losses inherent in the remainder of the loan and lease portfolio. Credit losses are charged and recoveries are credited to the ACL. We utilize an internal risk grading system for commercial credits. Those credits that meet the following criteria are subject to individual evaluation: the loan has an outstanding bank share balance of $1 million or greater and (i) has a criticized risk rating, (ii) is in nonaccrual status, (iii) is a TDR, or (iv) is 90 days or more past due. The borrower’s cash flow, adequacy of collateral coverage, and other options available to CTBI, including legal remedies, are evaluated. We evaluate the collectability of both principal and interest when assessing the need for loss provision. Historical loss rates are analyzed and applied to other commercial loan segments not subject to individual evaluation. Homogenous loans, such as consumer installment, residential mortgages, and home equity lines are not individually risk graded. The associated ACL for these loans is measured in pools with similar risk characteristics under ASC 326. When any secured commercial loan is considered uncollectable, whether past due or not, a current assessment of the value of the underlying collateral is made. If the balance of the loan exceeds the fair value of the collateral, the loan is placed on nonaccrual and the loan is charged down to the value of the collateral less estimated cost to sell. For commercial loans greater than $ When the foreclosed collateral has been legally assigned to CTBI, the estimated fair value of the collateral less costs to sell is then transferred to other real estate owned or other repossessed assets, and a charge-off is taken for any remaining balance. When any unsecured commercial loan is considered uncollectable the loan is charged off no later than at days past due. All closed-end consumer loans (excluding conventional 1-4 family residential loans and installment and revolving loans secured by real estate) are charged off no later than 120 days (5 monthly payments) delinquent. If a loan is considered uncollectable, it is charged off earlier than 120 days delinquent. For conventional 1-4 family residential loans and installment and revolving loans secured by real estate, when a loan is 90 days past due, a current assessment of the value of the real estate is made. If the balance of the loan exceeds the fair value of the property, the loan is placed on nonaccrual. Foreclosure proceedings are normally initiated after 120 days. When the foreclosed property has been legally assigned to CTBI, the fair value less estimated costs to sell is transferred to other real estate owned and the remaining balance is taken as a charge-off. Historical loss rates for loans are adjusted for significant factors that, in management’s judgment, reflect the impact of any current conditions on loss recognition. With the implementation of ASC 326, weighted average life (“WAL”) calculations were completed as a tool to determine the life of CTBI’s various loan segments. Vintage modeling was used to determine the life of loan losses for consumer and residential real estate loans. Static pool modeling was used to determine the life of loan losses for commercial loan segments. Qualitative factors used to derive CTBI’s total ACL include delinquency trends, current economic conditions and trends, strength of supervision and administration of the loan portfolio, levels of underperforming loans, trends in loan losses, and underwriting exceptions. Forecasting factors including unemployment rates and industry specific forecasts for industries in which our total exposure is 5% of capital or greater are also included as factors in the ACL model. Management continually reevaluates the other subjective factors included in its ACL analysis. Other Real Estate Owned Income Taxes

Securities [Abstract]
Securities	Note 3 – Securities Debt securities are classified into held-to-maturity and available-for-sale categories. Held-to-maturity (HTM) securities are those that CTBI has the positive intent and ability to hold to maturity and are reported at amortized cost. Available-for-sale (AFS) securities are those that CTBI may decide to sell if needed for liquidity, asset-liability management or other reasons. Available-for-sale securities are reported at fair value, with unrealized gains or losses included as a separate component of equity, net of tax. As of March 31 CTBI had held-to-maturity securities. The amortized cost and fair value of debt securities at March are summarized as follows: Available-for-Sale (in thousands) Amortized Cost Gross Unrealized Gains Gross Unrealized Losses Fair Value U.S. Treasury and government agencies $ 205,355 $ 419 $ (2,155 ) $ 203,619 State and political subdivisions 219,389 5,416 (4,688 ) 220,117 U.S. government sponsored agency mortgage-backed securities 669,134 8,616 (2,918 ) 674,832 Other debt securities 56,346 301 (20 ) 56,627 Total available-for-sale securities $ 1,150,224 $ 14,752 $ (9,781 ) $ 1,155,195 The amortized cost and fair value of debt securities at December are summarized as follows: Available-for-Sale (in thousands) Amortized Cost Gross Unrealized Gains Gross Unrealized Losses Fair Value U.S. Treasury and government agencies $ 148,507 $ 483 $ (197 ) $ 148,793 State and political subdivisions 133,287 7,132 (3 ) 140,416 U.S. government sponsored agency mortgage-backed securities 640,537 11,648 (378 ) 651,807 Other debt securities 56,443 10 (208 ) 56,245 Total available-for-sale securities $ 978,774 $ 19,273 $ (786 ) $ 997,261 The amortized cost and fair value of debt securities at March by contractual maturity are shown below.

Loans [Abstract]
Loans	Note 4 – Loans Major classifications of loans, net of unearned income, deferred loan origination costs and fees, and net premiums on acquired loans, are summarized as follows: (in thousands) March 31 2021 December 31 2020 Hotel/motel $ 258,974 $ 260,699 Commercial real estate residential 305,079 287,928 Commercial real estate nonresidential 732,978 743,238 Dealer floorplans 63,545 69,087 Commercial other 285,176 279,908 Commercial unsecured SBA PPP 254,732 252,667 Commercial loans 1,900,484 1,893,527 Real estate mortgage 770,026 784,559 Home equity lines 101,595 103,770 Residential loans 871,621 888,329 Consumer direct 149,394 152,304 Consumer indirect 617,305 620,051 Consumer loans 766,699 772,355 Loans and lease financing $ 3,538,804 $ 3,554,211 The loan portfolios presented above are net of unearned fees and unamortized premiums. Unearned fees included above totaled $9.4 million as of March 31, 2021 and $9.3 million as of December 31, 2020 while the unamortized premiums on the indirect lending portfolio totaled $23.9 million as of March 31, 2021 and $23.8 million as of December 31, 2020. CTBI has segregated and evaluates its loan portfolio through ten portfolio segments with similar risk characteristics. CTBI serves customers in small and mid-sized communities in eastern, northeastern, central, and south central Kentucky, southern West Virginia, and northeastern Tennessee. Therefore, CTBI’s exposure to credit risk is significantly affected by changes in these communities. Hotel/motel loans are a significant concentration for CTBI, representing approximately of total loans. This industry has unique risk characteristics as it is highly susceptible to changes in the domestic and global economic environments, which can cause the industry to experience substantial volatility. Additionally, any hotel/motel construction loans would be included in this segment as CTBI’s construction loans are primarily completed as loan going from construction to permanent financing. These loans are originated based on the borrower’s ability to service the debt and arily based on the fair value of the underlying collateral. Commercial real estate residential loans are commercial purpose construction and permanent financed loans for commercial purpose - family/multi-family properties. These loans are originated based on the borrower’s ability to service the debt and arily based on the fair value of the underlying collateral. Commercial real estate nonresidential loans are secured by nonfarm, nonresidential properties, farmland, and other commercial real estate. These loans are originated based on the borrower’s ability to service the debt and arily based on the fair value of the underlying collateral. Construction for commercial real estate nonresidential loans are also included in this segment as these loans are generally loan for construction to permanent financing. Dealer floorplans consist of loans to dealerships to finance inventory and are collateralized under a blanket security agreement and without specific liens on individual units. This risk is mitigated by the use of periodic inventory audits. These audits are performed monthly and follow up is required on any out of compliance items identified. These audits are subject to increasing frequency when fact patterns suggest more scrutiny is required . Commercial other loans consist of agricultural loans, receivable financing, loans to financial institutions, loans for purchasing or carrying securities, and other commercial purpose loans. Commercial loans are underwritten based on the borrower’s ability to service debt from the business’s underlying cash flows. As a general practice, we obtain collateral such as equipment, or other assets, although such loans may be uncollateralized but guaranteed. CTBI’s participation in the Paycheck Protection Program (“PPP”) established by the CARES Act resulted in the creation of a new loan segment of unsecured commercial other loans that are one hundred percent guaranteed by the Small Business Administration (“SBA”). These loans, which are subject to forgiveness, have maturities of either two or three to five years, depending on when the loan was made. These loans currently have no allowance for credit losses. Residential real estate loans are a mixture of fixed rate and adjustable rate and lien residential mortgage loans and also include real estate construction loans which are typically for owner-occupied properties. The terms of the real estate construction loans are generally short-term with permanent financing upon completion. As a policy, CTBI holds adjustable rate loans and sells the majority of its fixed rate lien mortgage loans into the ary market. Changes in interest rates or market conditions may impact a borrower’s ability to meet contractual principal and interest payments. Residential real estate loans are secured by real property. Home equity lines are primarily revolving adjustable rate credit lines secured by real property. Consumer direct loans are a mixture of fixed rate and adjustable rate products comprised of unsecured loans, consumer revolving credit lines, deposit secured loans, and all other consumer purpose loans. Consumer indirect loans are fixed rate loans secured by automobiles, trucks, vans, and recreational vehicles originated at the selling dealership underwritten and purchased by CTBI’s indirect lending department. Both new and used products are financed. Only dealers who have executed dealer agreements with CTBI participate in the indirect lending program. Not included in the loan balances above were loans held for sale in the amount of $17.7 million at March 31, 2021 and $23.3 million at December 31, 2020. The following tables present the balance in the allowance for credit losses (“ACL”) for the periods ended March 31, 2021, December 31, 2020 and March 31, 2020: Three Months Ended March 31, 2021 (in thousands) Hotel/ Motel Commercial Real Estate Residential Commercial Real Estate Nonresidential Dealer Floorplans Commercial Other Real Estate Mortgage Home Equity Consumer Direct Consumer Indirect Total ACL Beginning balance $ 6,356 $ 4,464 $ 11,086 $ 1,382 $ 4,289 $ 7,832 $ 844 $ 1,863 $ 9,906 $ 48,022 Provision charged to expense 308 199 (135 ) (64 ) 269 (690 ) (93 ) (14 ) (2,279 ) (2,499 ) Losses charged off 0 (24 ) (151 ) 0 (112 ) (8 ) (5 ) (154 ) (1,016 ) (1,470 ) Recoveries 0 2 13 0 125 9 4 116 1,024 1,293 Ending balance $ 6,664 $ 4,641 $ 10,813 $ 1,318 $ 4,571 $ 7,143 $ 750 $ 1,811 $ 7,635 $ 45,346 Year Ended December 31, 2020 (in thousands) Hotel/Motel Commercial Real Estate Residential Commercial Real Estate Nonresidential Dealer Floorplans Commercial Other Real Estate Mortgage Home Equity Consumer Direct Consumer Indirect Total ACL Beginning balance, prior to adoption of ASC 326 $ 3,371 $ 3,439 $ 8,515 $ 802 $ 5,556 $ 4,604 $ 897 $ 1,711 $ 6,201 $ 35,096 Impact of adoption of ASC 326 170 (721 ) 119 820 (391 ) 1,893 (75 ) (40 ) 1,265 3,040 Provision charged to expense 2,858 1,772 3,303 (214 ) 2,040 1,584 16 609 4,079 16,047 Losses charged off (43 ) (182 ) (941 ) (26 ) (3,339 ) (321 ) (4 ) (927 ) (4,670 ) (10,453 ) Recoveries 0 156 90 0 423 72 10 510 3,031 4,292 Ending balance $ 6,356 $ 4,464 $ 11,086 $ 1,382 $ 4,289 $ 7,832 $ 844 $ 1,863 $ 9,906 $ 48,022 Three Months Ended March 31, 2020 (in thousands) Hotel/ Motel Commercial Real Estate Residential Commercial Real Estate Nonresidential Dealer Floorplans Commercial Other Real Estate Mortgage Home Equity Consumer Direct Consumer Indirect Total ACL Beginning balance, prior to adoption of ASC 326 $ 3,371 $ 3,439 $ 8,515 $ 802 $ 5,556 $ 4,604 $ 897 $ 1,711 $ 6,201 $ 35,096 Impact of adoption of ASC 326 170 (721 ) 119 820 (391 ) 1,893 (75 ) (40 ) 1,265 3,040 Provision charged to expense 2,381 1,337 2,984 91 1,434 1,099 67 739 2,575 12,707 Losses charged off 0 (51 ) (59 ) 0 (359 ) (60 ) 0 (369 ) (1,517 ) (2,415 ) Recoveries 0 8 4 0 169 7 1 122 706 1,017 Ending balance $ 5,922 $ 4,012 $ 11,563 $ 1,713 $ 6,409 $ 7,543 $ 890 $ 2,163 $ 9,230 $ 49,445 CTBI derived its ACL balance by using vintage modeling for the consumer and residential portfolios. Static pool models incorporating losses by credit risk rating were developed to determine credit loss balances for the commercial loan segments. Qualitative loss factors are based on CTBI’s judgment of delinquency trends, level of nonperforming loans, trend in loan losses, supervision and administration, quality control exceptions, and reasonable and supportable forecasts based on unemployment rates and industry concentrations. CTBI has determined that twelve months represents a reasonable and supportable forecast period and reverts back to a historical loss rate immediately. CTBI leverages economic projections from a reputable and independent third party to form its loss driver forecasts over the twelve month forecast period. Other internal and external indicators of economic forecasts are also considered by CTBI when developing the forecast metrics. CTBI also has an inherent model risk allocation included in its ACL calculation to allow for certain known model limitations as well as other potential risks not quantified elsewhere. Management has identified the following known model limitations and made adjustments through this portion of the calculation for them: (1) The inability to completely identify revolving lines of credit within the commercial other segment. Management had to make assumptions regarding commercial renewals as those renewals are not tracked well by its loan system. (2) The inability within the model to estimate the value of modifications made under troubled debt restructurings. Management has manually calculated the estimated impact based on research of modified terms for troubled debt restructurings. With the continued impact of the global COVID-19 pandemic and the fact that there is no immediate end foreseen, this has been identified as a significant specific event that could impact our customers’ ability to pay. CTBI added a new factor during the prior year as an allocation to recognize when there are significant events occurring that could impact the loan portfolio. Management noted that the qualitative factors for current delinquency trends and our levels of nonperforming loans were driving a reduction in the overall calculation for our ACL. Management was concerned that these factors may have been artificially influenced by the current credit environment and the number of loans that have received payment deferrals. Given this uncertainty, management elected to maintain this significant event qualitative factor to anticipate continued impact of COVID-19 once further deferments are no longer available and SBA Payroll Protection Programs end. We recognized a recapture of allowance for credit losses with a credit to provision for credit losses of $2.5 million for the first quarter of 2021, compared to a provision for credit losses of $1.0 million for the prior quarter and $12.7 million for the first quarter of 2020. The change in the provision for credit losses compared to the fourth quarter of 2020 was due primarily to the improvement in net charge off experience affecting our vintage loss analysis in several segments, the most significant of those being the indirect lending and residential lending segments. The indirect lending segment experienced no net losses in the quarter, compared to the 12 quarter rolling average losses of 0.35 percent. The residential lending segment experienced no net losses in the quarter compared to the 12 quarter rolling average of 0.07 percent. Overall, the decrease in the allowance for credit losses attributed to historical loss factors was $2.4 million. Our reserve coverage (allowance for credit losses to nonperforming loans) at March 31, 2021 was 215.5% compared to 180.7% at December 31, 2020 and 139.8% at March 31, 2020.

This industry has unique risk characteristics as it is highly susceptible to changes in the domestic and global economic environments, which can cause the industry to experience substantial volatility. These loans are viewed primarily as cash flow loans and secondarily as loans secured by real estate. Hotel/motel lending typically involves higher loan principal amounts and the repayment of these loans is generally dependent on the successful operation of the property securing the loan or the business conducted on the property securing the loan. Management monitors and evaluates all commercial real estate loans based on collateral and risk grade criteria. Commercial construction loans generally are made to customers for the purpose of building income-producing properties, and any hotel/motel construction loan would be included in this segment. Personal guarantees of the principals are generally required. Such loans are made on a projected cash flow basis and are secured by the project being constructed. Construction loan draw procedures are included in each specific loan agreement, including required documentation items and inspection requirements. Construction loans may convert to term loans at the end of the construction period, or may be repaid by the take-out commitment from another financing source. If the loan is to convert to a term loan, the repayment ability is based on the borrower’s projected cash flow. Risk is mitigated during the construction phase by requiring proper documentation and inspections whenever a draw is requested. Loans in amounts greater than $500,000 generally require a performance bond to be posted by the general contractor to assure completion of the project. Commercial real estate residential loans are commercial purpose construction and permanent financed loans for commercial purpose 1-4 family/multi-family properties. All commercial real estate loans are viewed primarily as cash flow loans and secondarily as loans secured by real estate. Management monitors and evaluates all commercial real estate loans based on collateral and risk grade criteria. Commercial residential construction loans generally are made to customers for the purpose of building income-producing properties. Personal guarantees of the principals are generally required. Such loans are made on a projected cash flow basis and are secured by the project being constructed. Construction loan draw procedures are included in each specific loan agreement, including required documentation items and inspection requirements. Construction loans may convert to term loans at the end of the construction period, or may be repaid by the take-out commitment from another financing source. If the loan is to convert to a term loan, the repayment ability is based on the borrower’s projected cash flow. Risk is mitigated during the construction phase by requiring proper documentation and inspections whenever a draw is requested. Loans in amounts greater than $500,000 generally require a performance bond to be posted by the general contractor to assure completion of the project. Commercial real estate nonresidential loans are secured by nonfarm, nonresidential properties, farmland, and other commercial real estate. Construction for commercial real estate nonresidential loans are also included in this segment as these loans are generally one loan for construction to permanent financing. All commercial real estate loans are viewed primarily as cash flow loans and secondarily as loans secured by real estate. Management monitors and evaluates all commercial real estate loans based on collateral and risk grade criteria. Commercial nonresidential construction loans generally are made to customers for the purpose of building income-producing properties. Personal guarantees of the principals are generally required.

Risk is mitigated during the construction phase by requiring proper documentation and inspections whenever a draw is requested. Loans in amounts greater than $500,000 generally require a performance bond to be posted by the general contractor to assure completion of the project. Dealer floorplans are segmented separately as they are a unique product with unique risk factors. CTBI maintains strict processing procedures over its floorplan product with any exceptions requested by a loan officer approved by the appropriate loan committee and the floorplan manager. Commercial other loans are primarily based on the identified cash flows of the borrower and secondarily on the underlying collateral provided by the borrower. The cash flows of borrowers, however, may not be as expected and the collateral securing these loans may fluctuate in value. Most commercial loans are secured by the assets being financed or other business assets such as accounts receivable or inventory and may incorporate a personal guarantee; however, some short-term loans may be made on an unsecured basis. In the case of loans secured by accounts receivable, the availability of funds for the repayment of these loans may be substantially dependent on the ability of the borrower to collect amounts due from its customers. As we underwrite our equipment lease financing in a manner similar to our commercial loan portfolio described below, the risk characteristics for this portfolio mirror that of the commercial loan portfolio. CTBI’s participation in the CARES Act PPP loan program has resulted in a new loan segment of unsecured commercial other loans that are one hundred percent SBA guaranteed. These loans, which are subject to forgiveness, have maturities of either two or three to five years, depending on when the loans were made. These loans currently have no allowance for credit losses. With respect to residential loans that are secured by 1-4 family residences and are generally owner occupied, CTBI generally establishes a maximum loan-to-value ratio and requires private mortgage insurance if that ratio is exceeded. Home equity loans are typically secured by a subordinate interest in 1-4 family residences. Residential construction loans are handled through the home mortgage area of the bank. The repayment ability of the borrower and the maximum loan-to-value ratio are calculated using the normal mortgage lending criteria. Draws are processed based on percentage of completion stages including normal inspection procedures. Such loans generally convert to term loans after the completion of construction. Consumer loans are secured by consumer assets such as automobiles or recreational vehicles. Some consumer loans are unsecured such as small installment loans and certain lines of credit. Our determination of a borrower’s ability to repay these loans is primarily dependent on the personal income and credit rating of the borrowers, which can be impacted by economic conditions in their market areas such as unemployment levels. Repayment can also be impacted by changes in property values on residential properties. Risk is mitigated by the fact that the loans are of smaller individual amounts and spread over a large number of borrowers. The indirect lending area of the bank generally deals with purchasing/funding consumer contracts with new and used automobile dealers. The dealers generate consumer loan applications which are forwarded to the indirect loan processing area for approval or denial. Loan approvals or denials are based on the creditworthiness and repayment ability of the borrower, and on the collateral value. The dealers may have limited recourse agreements with CTB. Credit Quality Indicators: CTBI categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt such as: current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. CTBI also considers the fair value of the underlying collateral and the strength and willingness of the guarantor(s). CTBI analyzes commercial loans individually by classifying the loans as to credit risk. Loans classified as loss, doubtful, substandard, or special mention are reviewed quarterly by CTBI for further deterioration or improvement to determine if appropriately classified and valued if deemed impaired. All other commercial loan reviews are completed every 12 to 18 months. In addition, during the renewal process of any loan, as well as if a loan becomes past due or if other information becomes available, CTBI will evaluate the loan grade. CTBI uses the following definitions for risk ratings: ➢ Pass ➢ Watch ➢ Other assets especially mentioned (OAEM) ➢ Substandard ➢ Doubtful The following tables present the credit risk profile of CTBI’s

Repurchase Agreements [Abstract]
Repurchase Agreements	Note 6 – Repurchase Agreements We utilize securities sold under agreements to repurchase to facilitate the needs of our customers and provide additional funding to our balance sheet. Repurchase agreements are transactions whereby we offer to sell to a counterparty an undivided interest in an eligible security at an agreed upon purchase price, and which obligates CTBI to repurchase the security on an agreed upon date at an agreed upon repurchase price plus interest at an agreed upon rate. Securities sold under agreements to repurchase are recorded at the amount of cash received in connection with the transaction and are reflected in the accompanying consolidated balance sheets. We monitor collateral levels on a continuous basis and maintain records of each transaction specifically describing the applicable security and the counterparty’s fractional interest in that security, and we segregate the security from its general assets in accordance with regulations governing custodial holdings of securities. The primary risk with our repurchase agreements is market risk associated with the securities securing the transactions, as we may be required to provide additional collateral based on fair value changes of the underlying securities. Securities pledged as collateral under repurchase agreements are maintained with our safekeeping agents. The carrying value of investment securities available-for-sale pledged as collateral under repurchase agreements totaled $396.2 million and $397.4 million at March 31, 2021 The remaining contractual maturity of the securities sold under agreements to repurchase by class of collateral pledged included in the accompanying consolidated balance sheets as of March and December is presented in the following tables: March 31, 2021 Remaining Contractual Maturity of the Agreements (in thousands) Overnight and Continuous Up to 30 days 30-90 days Greater Than 90 days Total Repurchase agreements and repurchase-to-maturity transactions: U.S. Treasury and government agencies $ 3,894 $ 22 $ 0 $ 38,051 $ 41,967 State and political subdivisions 63,479 179 0 32,463 96,121 U.S. government sponsored agency mortgage-backed securities 26,952 1,104 0 188,091 216,147 Total $ 94,325 $ 1,305 $ 0 $ 258,605 $ 354,235 December 31, 2020 Remaining Contractual Maturity of the Agreements (in thousands) Overnight and Continuous Up to 30 days 30-90 days Greater Than 90 days Total Repurchase agreements and repurchase-to-maturity transactions: U.S. Treasury and government agencies $ 8,777 $ 0 $ 2,831 $ 31,800 $ 43,408 State and political subdivisions 54,639 0 1,132 21,421 77,192 U.S. government sponsored agency mortgage-backed securities 33,040 0 101,037 101,185 235,262 Total $ 96,456 $ 0 $ 105,000 $ 154,406 $ 355,862

Fair Market Value of Financial Assets and Liabilities [Abstract]
Fair Market Value of Financial Assets and Liabilities	Note 7 – Fair Market Value of Financial Assets and Liabilities Fair Value Measurements ASC 820, Fair Value Measurements Level 1 Inputs – Quoted prices in active markets for identical assets or liabilities. Level 2 Inputs – Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These might include quoted prices for similar assets and liabilities in active markets, and inputs other than quoted prices that are observable for the asset or liability, such as interest rates and yield curves that are observable at commonly quoted intervals. Level 3 Inputs – Unobservable inputs for determining the fair values of assets or liabilities that reflect an entity’s own assumptions about the assumptions that market participants would use in determining an exit price for the assets or liabilities. Recurring Measurements The following tables present the fair value measurements of assets recognized in the accompanying balance sheets measured at fair value on a recurring basis as of March 31, 2021 and December 31, 2020 and indicate the level within the fair value hierarchy of the valuation techniques.

These valuation methodologies were applied to all of CTBI’s financial assets carried at fair value. CTBI had no liabilities measured and recorded at fair value as of March 31, 2021 and December 31, 2020. There have been no significant changes in the valuation techniques during the quarter ended March 31, 2021. For assets classified within Level 3 of the fair value hierarchy, the process used to develop the reported fair value is described below. Available-for-Sale Securities Securities classified as available-for-sale are reported at fair value on a recurring basis. U.S. Treasury and government agencies are classified as Level 1 of the valuation hierarchy where quoted market prices are available in the active market on which the individual securities are traded. If quoted market prices are not available, CTBI obtains fair value measurements from an independent pricing service, such as Interactive Data, which utilizes pricing models to determine fair value measurement. CTBI reviews the pricing quarterly to verify the reasonableness of the pricing. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond’s terms and conditions, among other factors. U.S. Treasury and government agencies, state and political subdivisions, U.S. government sponsored agency mortgage-backed securities, and other debt securities are classified as Level 2 inputs. In certain cases where Level 1 or Level 2 inputs are not available, securities are classified within Level 3 of the hierarchy. Fair value determinations for Level 3 measurements are estimated on a quarterly basis where assumptions used are reviewed to ensure the estimated fair value complies with accounting standards generally accepted in the United States. Equity Securities at Fair Value As of March 31, 2021 and December 31, 2020, the only securities owned by CTBI that were valued using Level 3 criteria are Visa Class B Stock (included in equity securities at fair value). Fair value for Visa Class B Stock is determined by an independent third party utilizing assumptions about factors such as quarterly common stock dividend payments, the conversion of the securities to the relevant Class A Stock shares subject to the prevailing conversion rate and conversion date. See the table below for inputs and valuation techniques used for Level 3 equity securities. Mortgage Servicing Rights Mortgage servicing rights do not trade in an active, open market with readily observable prices. CTBI reports mortgage servicing rights at fair value on a recurring basis with subsequent remeasurement of MSRs based on change in fair value. In determining fair value, CTBI utilizes the expertise of an independent third party. Accordingly, fair value is determined by the independent third party by utilizing assumptions about factors such as mortgage interest rates, discount rates, mortgage loan prepayment speeds, market trends and industry demand. Due to the nature of the valuation inputs, mortgage servicing rights are classified within Level 3 of the hierarchy. Fair value determinations for Level 3 measurements of mortgage servicing rights are tested for impairment on a quarterly basis where assumptions used are reviewed to ensure the estimated fair value complies with accounting standards generally accepted in the United States. We have reviewed the assumptions, processes, and conclusions of the third party provider. We have determined these assumptions, processes, and conclusions to be reasonable and appropriate in determining the fair value of this asset. See the table below for inputs and valuation techniques used for Level 3 mortgage servicing rights.

For assets classified within Level 3 of the fair value hierarchy, the process used to develop the reported fair value is described below. Collateral Dependent Loans The estimated fair value of collateral-dependent loans is based on the appraised fair value of the collateral, less estimated cost to sell. Collateral-dependent loans are classified within Level 3 of the fair value hierarchy. CTBI considers the appraisal or evaluation as the starting point for determining fair value and then considers other factors and events in the environment that may affect the fair value. Appraisals of the collateral underlying collateral-dependent loans are obtained when the loan is determined to be collateral-dependent and subsequently as deemed necessary by the Chief Credit Officer. Appraisals are reviewed for accuracy and consistency by the Chief Credit Officer. Appraisers are selected from the list of approved appraisers maintained by management. The appraised values are reduced by discounts to consider lack of marketability and estimated cost to sell if repayment or satisfaction of the loan is dependent on the sale of the collateral. These discounts and estimates are developed by the Chief Credit Officer by comparison to historical results. Loans considered collateral dependent are loans for which the repayment is expected to be provided substantially through the operation or sale of the collateral when the borrower is experiencing financial difficulty in accordance with ASC - - - Quarter-to-date fair value adjustments on collateral- dependent loans disclosed above were , , and for the quarters ended March December and March respectively. Other Real Estate Owned In accordance with the provisions of ASC Property, Plant, and Equipment, other real estate owned (“OREO”) is carried at the lower of fair value at acquisition date or current estimated fair value, less estimated cost to sell when the real estate is acquired. Estimated fair value of OREO is based on appraisals or evaluations. OREO is classified within Level of the fair value hierarchy. Long-lived assets are subject to nonrecurring fair value adjustments to reflect subsequent partial write-downs that are based on the observable market price or current appraised value of the collateral. Quarter-to-date fair value adjustments on other real estate owned disclosed above were , , and for the quarters ended March December and March respectively. Our policy for determining the frequency of periodic reviews is based upon consideration of the specific properties and the known or perceived market fluctuations in a particular market and is typically between 12 and 18 months but generally not more than 24 months. Appraisers are selected from the list of approved appraisers maintained by management. Unobservable (Level 3) Inputs The following tables present quantitative information about unobservable inputs used in recurring and nonrecurring Level 3 fair value measurements at March 31, 2021 and December 31, 2020.

Equity Securities at Fair Value Fair market value for equity securities is derived based on unobservable inputs, such as the discount rate, quarterly dividends payable to the Visa Class B common stock and the prevailing conversion rate at the conversion date. The most recent conversion rate of 1.6228 and the most recent dividend rate of 0.5193 were used to derive the fair value estimate. Significant increases (decreases) in either of those inputs in isolation would result in a significantly lower (higher) fair value measurement. Generally, a change in the assumption used for discount rate is accompanied by a directionally opposite change in the fair value estimate. Mortgage Servicing Rights Fair market value for mortgage servicing rights is derived based on unobservable inputs, such as prepayment speeds of the underlying loans generated using the Andrew Davidson Prepayment Model, FHLMC/FNMA guidelines, the weighted average life of the loan, the discount rate, the weighted average coupon, and the weighted average default rate. Significant increases (decreases) in either of those inputs in isolation would result in a significantly lower (higher) fair value measurement. Generally, a change in the assumption used for prepayment speeds is accompanied by a directionally opposite change in the assumption for interest rates. Fair Value of Financial Instruments The following table presents estimated fair value of CTBI’s financial instruments as of March 31, 2021 and indicates the level within the fair value hierarchy of the valuation techniques. In accordance with the adoption of ASU 2016-01, the fair values as of March 31, 2021 were measured using an exit price notion.

Revenue Recognition

Revenue Recognition	3 Months Ended

Revenue Recognition [Abstract]
Revenue Recognition	Note 8 – Revenue Recognition CTBI’s primary source of revenue is interest income generated from loans and investment securities. Interest income is recognized according to the terms of the financial instrument agreement over the life of the loan or investment security unless it is determined that the counterparty is unable to continue making interest payments. Interest income also includes prepaid interest fees from commercial customers, which approximates the interest foregone on the balance of the loan prepaid. CTBI’s additional source of income, also referred to as noninterest income, includes service charges on deposit accounts, gains on sales of loans, trust and wealth management income, loan related fees, brokerage revenue, and other miscellaneous income and is largely based on contracts with customers. In these cases, CTBI recognizes revenue when it satisfies a performance obligation by transferring control over a product or service to a customer. CTBI considers a customer to be any party to which we will provide goods or services that are an output of CTBI’s ordinary activities in exchange for consideration. There is little seasonality with regards to revenue from contracts with customers and all inter-company revenue is eliminated when CTBI’s financial statements are consolidated. Generally, CTBI enters into contracts with customers that are short-term in nature where the performance obligations are fulfilled and payment is processed at the same time. Such examples include revenue related to merchant fees, interchange fees, and investment services income. In addition, revenue generated from existing customer relationships such as deposit accounts are also considered short-term in nature, because the relationship may be terminated at any time and payment is processed at the time performance obligations are fulfilled. As a result, CTBI does t have contract assets, contract liabilities, or related receivable accounts for contracts with customers. In cases where collectability is a concern, CTBI does not record revenue. Generally, the pricing of transactions between CTBI and each customer is either (i) established within a legally enforceable contract between the two parties, as is the case with loan sales, or (ii) disclosed to the customer at a specific point in time, as is the case when a deposit account is opened or before a new loan is underwritten. Fees are usually fixed at a specific amount or as a percentage of a transaction amount. No judgment or estimates by management are required to record revenue related to these transactions and pricing is clearly identified within these contracts. CTBI primarily operates in Kentucky and contiguous areas. Therefore, all significant operating decisions are based upon analysis of CTBI as operating segment. We disaggregate our revenue from contracts with customers by contract-type and timing of revenue recognition, as we believe it best depicts how the nature, amount, timing and uncertainty of our revenue and cash flows are affected by economic factors. Noninterest income not generated from customers during CTBI’s ordinary activities primarily relates to mortgage servicing rights, gains/losses on the sale of investment securities, gains/losses on the sale of other real estate owned, gains/losses on the sale of property, plant and equipment, and income from bank owned life insurance. For more information related to our components of noninterest income, see the Condensed Consolidated Statements of Income and Comprehensive Income above.

At March 31, 2021, the number of customers with CARES Act deferrals reduced to 226 for a total outstanding amount of $81.8 million. The majority of our CARES Act deferrals have been 90 day deferrals. Total outstanding deferrals include 73 commercial loan deferrals with a total outstanding amount of $73.8 million, 83 residential loan deferrals with a total outstanding amount of $6.5 million, and 70 consumer loan deferrals with a total outstanding amount of $1.5 million. Included in the commercial loan deferrals are 20 four time deferrals totaling $40.5 million and 2 five time deferrals totaling $10.6 million. In most cases, these loans have been downgraded; however, they remain within the pass category, as little to no loss is anticipated. One of the loans was already graded substandard prior to the deferrals being granted. These loan deferrals and modifications have been executed consistent with the guidelines of the CARES Act. Pursuant to the CARES Act, these loan deferrals are not included in our nonperforming loans. At March 31, 2021, we had closed Paycheck Protection Program (PPP) loans totaling $ million, stemming from the CARES Act passed by Congress as a stimulus response to the potential economic impacts of COVID-19. The initial phase of the PPP program expired on August 8, 2020, and the loan forgiveness process began shortly thereafter. Through March 31, 2021, we have had of our PPP loans forgiven by the SBA in a total amount of $ million. During the first quarter, $ million in PPP loans were paid off or forgiven. An additional stimulus package, included as part of the Consolidated Appropriations Act 2021, was signed into law in late December 2020 providing for an additional $ billion in funding under the PPP, with authority to make loans under the program being extended through March 31, 2021. On March 11, 2021, the American Rescue Plan Act of 2021 was signed into law providing, among other things, additional funds for the PPP and an expansion of certain PPP eligibility requirements. On March 30, 2021, the PPP Extension Act of 2021 was signed into law giving applicants two additional months (through May 31, 2021) to apply for PPP loans and giving the SBA until June 30, 2021 to process loan applications. As of March 31, 2021, CTBI has closed loans totaling $ million in new PPP loans stemming from the second phase of lending authorized by the Consolidated Appropriations Act 2021

Summary of Significant Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation –
New Accounting Standards	New Accounting Standards ➢ Simplifying the Accounting for Income Taxes Income Taxes (Topic 740), Simplifying the Accounting for Income Taxes 1. Exception to the incremental approach for intra period tax allocation when there is a loss from continuing operations and income or a gain from other items (for example, discontinued operations or other comprehensive income); 2. Exception to the requirement to recognize a deferred tax liability for equity method investments when a foreign subsidiary becomes an equity method investment; 3. Exception to the ability not to recognize a deferred tax liability for a foreign subsidiary when a foreign equity method investment becomes a subsidiary; and 4. Exception to the general methodology for calculating income taxes in an interim period when a year-to-date loss exceeds the anticipated loss for the year. The amendments in this ASU also simplify the accounting for income taxes by doing the following: 1. Requiring that an entity recognize a franchise tax (or similar tax) that is partially based on income as an income-based tax and account for any incremental amount incurred as a non-income-based tax; 2. Requiring that an entity evaluate when a step up in the tax basis of goodwill should be considered part of the business combination in which the book goodwill was originally recognized and when it should be considered a separate transaction; 3. Specifying that an entity is not required to allocate the consolidated amount of current and deferred tax expense to a legal entity that is not subject to tax in its separate financial statements. However, an entity may elect to do so (on an entity-by-entity basis) for a legal entity that is both not subject to tax and disregarded by the taxing authority; 4. Requiring that an entity reflect the effect of an enacted change in tax laws or rates in the annual effective tax rate computation in the interim period that includes the enactment date; and 5. Making minor codification improvements for income taxes related to employee stock ownership plans and investments in qualified affordable housing projects accounted for using the equity method. For public business entities, the amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. CTBI adopted this ASU effective January 1, 2021 with no significant impact to our consolidated financial statements. ➢ Clarifying the Interactions between Topic 321 Topic 323 and Topic 815 a consensus of the FASB Emerging Task Force Investments—Equity Securities (Topic 321), Investments—Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815) Financial Instruments ➢ Facilitation of the Effects of Reference Rate Reform on Financial Reporting In response to concerns about structural risks of interbank offered rates, and, particularly, the risk of cessation of the London Interbank Offered Rate (LIBOR), regulators around the world have undertaken reference rate reform initiatives to identify alternative reference rates that are more observable or transaction-based and less susceptible to manipulation. The amendments in this ASU provide optional guidance for a limited time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting and provide optional expedients and exceptions for applying generally accepted accounting principles to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. This ASU applies only to contracts and hedging relationships that reference LIBOR or another reference rate expected to be discontinued due to reference rate reform. The expedients and exceptions provided by the amendments do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022.
Critical Accounting Policies and Estimates	Critical Accounting Policies and Estimates The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires the appropriate application of certain accounting policies, many of which require us to make estimates and assumptions about future events and their impact on amounts reported in our consolidated financial statements and related notes. Since future events and their impact cannot be determined with certainty, the actual results will inevitably differ from our estimates. Such differences could be material to the consolidated financial statements. We believe the application of accounting policies and the estimates required therein are reasonable. These accounting policies and estimates are constantly reevaluated, and adjustments are made when facts and circumstances dictate a change. Historically, we have found our application of accounting policies to be appropriate, and actual results have not differed materially from those determined using necessary estimates. Our accounting policies are described in Note 1 to the condensed consolidated financial statements. We have identified the following critical accounting policies:
Investments	Investments Investments – Debt Securities a. Trading securities . . b. Available-for-sale securities. Investments not classified as trading securities (nor as held-to-maturity securities) shall be classified as available-for-sale securities. We do not have any securities that are classified as trading securities. Available-for-sale securities are reported at fair value, with unrealized gains and losses included as a separate component of shareholders’ equity, net of tax. If declines in fair value are other than temporary, the carrying value of the securities is written down to fair value as a realized loss with a charge to income for the portion attributable to credit losses and a charge to other comprehensive income for the portion that is not credit related. Gains or losses on disposition of debt securities are computed by specific identification for those securities. Interest and dividend income, adjusted by amortization of purchase premium or discount, is included in earnings. An allowance is recognized for credit losses relative to available-for-sale securities rather than as a reduction in the cost basis of the security. Subsequent improvements in credit quality or reductions in estimated credit losses are recognized immediately as a reversal of the previously recorded allowance, which aligns the income statement recognition of credit losses with the reporting period in which changes occur. Held-to-maturity (“HTM”) securities are subject to an allowance for lifetime expected credit losses, determined by adjusting historical loss information for current conditions and reasonable and supportable forecasts. The forward-looking evaluation of lifetime expected losses will be performed on a pooled basis for debt securities that share similar risk characteristics. These allowances for expected losses must be made by the holder of the HTM debt security when the security is purchased. At March 31, 2021, CTBI held no securities designated as held-to-maturity. CTBI accounts for equity securities in accordance with Accounting Standards Codification (“ASC”) 321, Investments – Equity Securities Equity securities with a readily determinable fair value are required to be measured at fair value, with changes in fair value recognized through net income. Equity securities without a readily determinable fair value are carried at cost, less any impairment, if any, plus or minus changes resulting from observable price changes for identical or similar investments. As permitted by ASC 321-10-35-2, CTBI can make an irrevocable election to subsequently measure an equity security without a readily determinable fair value, and all identical or similar investments of the same issuer, including future purchases of identical or similar investments of the same issuer, at fair value. CTBI has made this election for its Visa Class B equity securities. The fair value of these securities was determined by a third party service provider using Level 3 inputs as defined in ASC 820, Fair Value Measurement
Loans	Loans The Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) included an election for banking institutions to not apply the guidance on accounting for troubled debt restructurings to loan modifications, such as extensions or deferrals, related to COVID-19 made between March 1, 2020 and the earlier of (i) December 31, 2020 or (ii) 60 days after the end of the COVID-19 national emergency. The relief can only be applied to modifications for borrowers that were not more than 30 days past due as of December 31, 2019. The ability to exclude COVID-19-related modifications as troubled debt restructurings was extended under the Consolidated Appropriations Act 2021 to the earlier of (i) 60 days after the COVID-19 national emergency and (ii) January 1, 2022. CTBI elected to adopt these provisions of the CARES Act, as extended by the Consolidated Appropriations Act 2021 . Loan origination and commitment fees and certain direct loan origination costs are deferred and the net amount amortized over the estimated life of the related loans, leases, or commitments as a yield adjustment.
Allowance for Credit Losses	Allowance for Credit Losses In the event that collection of principal becomes uncertain, CTBI has policies in place to reverse accrued interest in a timely manner. Therefore, CTBI elected ASU 2019-04 which allows that accrued interest would continue to be presented separately and not part of amortized cost on loan. The methodology used by CTBI is developed using the current loan balance, which is then compared to amortized cost balances to analyze the impact. The difference in amortized cost basis versus consideration of loan balances impacts the allowance for credit losses calculation by one basis point We maintain an allowance for credit losses (“ACL”) at a level that is appropriate to cover estimated credit losses on individually evaluated loans, as well as estimated credit losses inherent in the remainder of the loan and lease portfolio. Credit losses are charged and recoveries are credited to the ACL. We utilize an internal risk grading system for commercial credits. Those credits that meet the following criteria are subject to individual evaluation: the loan has an outstanding bank share balance of $1 million or greater and (i) has a criticized risk rating, (ii) is in nonaccrual status, (iii) is a TDR, or (iv) is 90 days or more past due. The borrower’s cash flow, adequacy of collateral coverage, and other options available to CTBI, including legal remedies, are evaluated. We evaluate the collectability of both principal and interest when assessing the need for loss provision. Historical loss rates are analyzed and applied to other commercial loan segments not subject to individual evaluation. Homogenous loans, such as consumer installment, residential mortgages, and home equity lines are not individually risk graded. The associated ACL for these loans is measured in pools with similar risk characteristics under ASC 326. When any secured commercial loan is considered uncollectable, whether past due or not, a current assessment of the value of the underlying collateral is made. If the balance of the loan exceeds the fair value of the collateral, the loan is placed on nonaccrual and the loan is charged down to the value of the collateral less estimated cost to sell. For commercial loans greater than $ When the foreclosed collateral has been legally assigned to CTBI, the estimated fair value of the collateral less costs to sell is then transferred to other real estate owned or other repossessed assets, and a charge-off is taken for any remaining balance. When any unsecured commercial loan is considered uncollectable the loan is charged off no later than at days past due. All closed-end consumer loans (excluding conventional 1-4 family residential loans and installment and revolving loans secured by real estate) are charged off no later than 120 days (5 monthly payments) delinquent. If a loan is considered uncollectable, it is charged off earlier than 120 days delinquent. For conventional 1-4 family residential loans and installment and revolving loans secured by real estate, when a loan is 90 days past due, a current assessment of the value of the real estate is made. If the balance of the loan exceeds the fair value of the property, the loan is placed on nonaccrual. Foreclosure proceedings are normally initiated after 120 days. When the foreclosed property has been legally assigned to CTBI, the fair value less estimated costs to sell is transferred to other real estate owned and the remaining balance is taken as a charge-off. Historical loss rates for loans are adjusted for significant factors that, in management’s judgment, reflect the impact of any current conditions on loss recognition. With the implementation of ASC 326, weighted average life (“WAL”) calculations were completed as a tool to determine the life of CTBI’s various loan segments. Vintage modeling was used to determine the life of loan losses for consumer and residential real estate loans. Static pool modeling was used to determine the life of loan losses for commercial loan segments. Qualitative factors used to derive CTBI’s total ACL include delinquency trends, current economic conditions and trends, strength of supervision and administration of the loan portfolio, levels of underperforming loans, trends in loan losses, and underwriting exceptions. Forecasting factors including unemployment rates and industry specific forecasts for industries in which our total exposure is 5% of capital or greater are also included as factors in the ACL model. Management continually reevaluates the other subjective factors included in its ACL analysis.

Defaulted Restructured Loans	Loans retain their accrual status at the time of their modification. As a result, if a loan is on nonaccrual at the time it is modified, it stays as nonaccrual, and if a loan is on accrual at the time of the modification, it generally stays on accrual. Commercial and consumer loans modified in a troubled debt restructuring are closely monitored for delinquency as an early indicator of possible future default. If loans modified in a troubled debt restructuring subsequently default, CTBI evaluates the loan for possible further impairment. The allowance for loan losses may be increased, adjustments may be made in the allocation of the allowance, or partial charge-offs may be taken to further write-down the carrying value of the loan. Presented below, segregated by class of loans, are loans that were modified as troubled debt restructurings within the past twelve months which have subsequently defaulted. CTBI considers a loan in default when it is 90 days or more past due or transferred to nonaccrual.
