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 September 30, 2019, the results of operations, other comprehensive income, and changes in shareholders’ equity for the three and nine months ended September 30, 2019 and 2018, and the cash flows for the nine months ended September 30, 2019 and 2018. 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 for the three and nine months ended September 30, 2019 and 2018 and the cash flows for the nine months ended September 30, 2019 and 2018 are not necessarily indicative of the results to be expected for the full year. The condensed consolidated balance sheet as of December 31, 2018 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, 2018, included in our annual report on Form 10-K. Principles of Consolidation – Reclassifications – New Accounting Standards ➢ Leases Leases (Topic 842). In August 2018, the FASB issued ASU 2018-11, Leases (Topic 842): Targeted Improvements. This ASU is intended to reduce costs and ease implementation of the leases standard for financial statement preparers. ASU 2018-11 provides a new transition method and a practical expedient for separating components of a contract. Transition: Comparative Reporting at Adoption The amendments in ASU 2018-11 provide entities with an additional (and optional) transition method to adopt the new leases standard. Under this new transition method, an entity initially applies the new leases standard at the adoption date and recognizes a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption consistent with preparers’ requests. Consequently, an entity’s reporting for the comparative periods presented in the financial statements in which it adopts the new leases standard will continue to be in accordance with current GAAP in Topic 840, Leases Separating Components of a Contract The amendments in ASU 2018-11 provide lessors with a practical expedient, by class of underlying asset, to not separate non-lease components from the associated lease component and, instead, to account for those components as a single component if the non-lease components otherwise would be accounted for under the new revenue guidance (Topic 606) and both of the following are met: • The timing and pattern of transfer of the non-lease component(s) and associated lease component are the same. • The lease component, if accounted for separately, would be classified as an operating lease. An entity electing this practical expedient (including an entity that accounts for the combined component entirely in Topic 606) is required to disclose certain information, by class of underlying asset, as specified in the ASU. We elected the optional transition method of the modified retrospective approach provided in ASU 2018-11 which was applied on January 1, 2019. CTBI also elected certain relief options offered in ASU 2016-02, including the package of practical expedients, the option not to separate lease and non-lease components, and instead to account for them as a single lease component for all classes of assets, the hindsight practical expedient to allow entities to use hindsight when determining lease term and impairment of right-of-use assets, and the option not to recognize right-of-use assets and lease liabilities that arise from short-term leases (i.e., leases with terms of twelve months or less). Refer to note 6, Leases, below for further information regarding the impact of adoption. ➢ Accounting for Credit Losses Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. For purchased financial assets with a more-than-insignificant amount of credit deterioration since origination (“PCD assets”) that are measured at amortized cost, the initial allowance for credit losses is added to the purchase price rather than being reported as a credit loss expense. Subsequent changes in the allowance for credit losses on PCD assets are recognized through the statement of income as a credit loss expense. Credit losses relating to available-for-sale debt securities will be recorded through an allowance for credit losses rather than as a direct write-down to the security. ASU 2016-13 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. CTBI has an implementation team working through the provisions of ASU 2016-13 including assessing the impact on its accounting and disclosures. The team has established the historical data that will be available and has identified the potential loan segments to be analyzed. The team has determined the portfolio methodologies and relevant economic factors to be utilized and will begin running parallel with its current model as part of the monthly fourth quarter 2019 loan portfolio analysis. ➢ Simplifying the Test for Goodwill Impairment Intangibles – Goodwill and Other (Topic 350) – Simplifying the Test for Goodwill Impairment ➢ Changes to the Disclosure Requirements for Fair Value Measurement Fair Value Measurement (Topic 820)—Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement Removals The following disclosure requirements were removed from Topic 820: • The amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy • The policy for timing of transfers between levels • The valuation processes for Level 3 fair value measurements Modifications The following disclosure requirements were modified in Topic 820: • For investments in certain entities that calculate net asset value, an entity is required to disclose the timing of liquidation of an investee’s assets and the date when restrictions from redemption might lapse only if the investee has communicated the timing to the entity or announced the timing publicly; and • The amendments clarify that the measurement uncertainty disclosure is to communicate information about the uncertainty in measurement as of the reporting date. Additions The following disclosure requirements were added to Topic 820: • The changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period; and • The range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. For certain unobservable inputs, an entity may disclose other quantitative information (such as the median or arithmetic average) in lieu of the weighted average if the entity determines that other quantitative information would be a more reasonable and rational method to reflect the distribution of unobservable inputs used to develop Level 3 fair value measurements. In addition, the amendments eliminate “at a minimum” from the phrase “an entity shall disclose at a minimum” to promote the appropriate exercise of discretion by entities when considering fair value measurement disclosures and to clarify that materiality is an appropriate consideration of entities and their auditors when evaluating disclosure requirements. CTBI plans to adopt ASU 2018-13 effective January 1, 2020 with minimal changes to our current reporting. ➢ Accounting for Costs of Implementing a Cloud Computing Service Agreement Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract The ASU aligns the following requirements for capitalizing implementation costs: • Those incurred in a hosting arrangement that is a service contract, and • Those incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). This ASU will be effective beginning January 1, 2020. We do not anticipate a significant impact to our consolidated financial statements. 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. 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. When the fair value of a security is below its amortized cost, and depending on the length of time the condition exists and the extent the fair market value is below amortized cost, additional analysis is performed to determine whether an other than temporary impairment condition exists. Available-for-sale and held-to-maturity securities are analyzed quarterly for possible other than temporary impairment. The analysis considers (i) whether we have the intent to sell our securities prior to recovery and/or maturity and (ii) whether it is more likely than not that we will not have to sell our securities prior to recovery and/or maturity. Often, the information available to conduct these assessments is limited and rapidly changing, making estimates of fair value subject to judgment. If actual information or conditions are different than estimated, the extent of the impairment of the security may be different than previously estimated, which could have a material effect on CTBI’s results of operations and financial condition. Subsequent to the January 1, 2018 effective date of ASU 2016-01, ASC 320 applies only to debt securities and 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. An election can be made, as permitted by ASC 321-10-35-2, to subsequently measure an equity security without a readily determinable fair value, at fair value. Equity securities held by CTBI include securities without readily determinable fair values. CTBI has elected to account for these securities at fair value. 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 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 Loan and Lease Losses – We maintain an allowance for loan and lease losses (“ALLL”) at a level that is appropriate to cover estimated credit losses on individually evaluated loans determined to be impaired, 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 ALLL. We utilize an internal risk grading system for commercial credits. Those larger commercial credits that exhibit probable or observed credit weaknesses are subject to individual review. The borrower’s cash flow, adequacy of collateral coverage, and other options available to CTBI, including legal remedies, are evaluated. The review of individual loans includes those loans that are impaired as defined by ASC 310-10-35, Impairment of a Loan A loan is considered impaired when, based on current information and events, it is probable that CTBI will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. Impairment is measured on a loan-by-loan basis for commercial and construction loans by either the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price, or the fair value of the collateral if the loan is collateral dependent. Homogenous loans, such as consumer installment, residential mortgages, and home equity lines are not individually risk graded. The associated ALLL for these loans is measured under ASC 450, Contingencies 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 or a specific reserve equal to the difference between book value of the loan and the fair value assigned to the collateral is created until such time as the loan is foreclosed. 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 90 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. We use twelve rolling quarters for our historical loss rate analysis. Factors that we consider include delinquency trends, current economic conditions and trends, strength of supervision and administration of the loan portfolio, levels of underperforming loans, level of recoveries to prior year’s charge-offs, trends in loan losses, industry concentrations and their relative strengths, amount of unsecured loans, and underwriting exceptions. Management continually reevaluates the other subjective factors included in its ALLL analysis. Other Real Estate Owned Income Taxes – Income tax expense is based on the taxes due on the consolidated tax return plus deferred taxes based on the expected future tax benefits and consequences of temporary differences between carrying amounts and tax bases of assets and liabilities, using enacted tax rates. Any interest and penalties incurred in connection with income taxes are recorded as a component of income tax expense in the consolidated financial statements. During the three and nine months ended September 30, 2019 and 2018, CTBI has not recognized a significant amount of interest expense or penalties in connection with income taxes. As a bank doing business in Kentucky, CTB is subject to a capital-based Kentucky bank franchise tax and exempt from Kentucky corporate income tax. However, in March 2019, Kentucky enacted HB354, which will transition CTB from the bank franchise tax to a corporate income tax beginning January 1, 2021. The current Kentucky corporate income tax rate is . As of March 31, 2019, CTBI recorded a deferred tax liability, net of the federal benefit, of $ million due to the enactment of HB354. In April 2019, Kentucky enacted HB458. HB458 allows for combined state income tax filing with CTBI, CTB, and CTIC. CTBI had previously filed a separate company return and generated net operating losses, in which it had maintained a valuation allowance against the related deferred tax asset. HB458 also allows for certain net operating losses to be utilized on a combined return. CTBI expects to file a combined return, beginning in 2021, and to utilize these previously generated losses. The tax benefit recorded in the second quarter 2019 to reverse the valuation allowance on the deferred tax asset for these losses was $ million.

Stock-Based Compensation [Abstract]
Stock-Based Compensation	Note 2 – Stock-Based Compensation CTBI’s compensation expense related to stock option grants was $ thousand and $ thousand, respectively, for the three and nine months ended September 30, 2019, and $ thousand and $ thousand for the three and nine months ended September 30, 2018. Restricted stock expense for the three and nine months ended September 30, 2019 was $ thousand and $ thousand, respectively, including $ thousand and $ thousand in dividends paid for each period. Restricted stock expense for the three and nine months ended September 30, 2018 was $ thousand and $ thousand, respectively, including $ thousand and $ thousand in dividends paid for each period. As of September 30, 2019, there was a total of $ thousand of unrecognized compensation expense related to unvested stock option awards that will be recognized as expense as the awards vest over a weighted average period of years and a total of $ million of unrecognized compensation expense related to restricted stock grants that will be recognized as expense as the awards vest over a weighted average period of years. There were stock options granted in the first nine months of both 2019 and 2018. There were and shares of restricted stock granted during the nine months ended September 30, 2019 and 2018, respectively. The restricted stock was issued pursuant to the terms of CTBI’s 2015 Stock Ownership Incentive Plan. The restrictions on the restricted stock will lapse ratably over . However, in the event of certain participant employee termination events occurring within months of a change in control of CTBI or the death of the participant, the restrictions will lapse, and in the event of the participant’s disability, the restrictions will lapse on a pro rata basis. The Compensation Committee will have discretion to review and revise restrictions applicable to a participant’s restricted stock in the event of the participant’s retirement.

Securities [Abstract]
Securities	Note 3 – Securities 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. The amortized cost and fair value of securities at September 30, 2019 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 $ 193,376 $ 610 $ (619 ) $ 193,367 State and political subdivisions 101,593 3,146 (37 ) 104,702 U.S. government sponsored agency mortgage-backed securities 316,745 4,806 (1,088 ) 320,463 Other debt securities 31,450 0 (6 ) 31,444 Total available-for-sale securities $ 643,164 $ 8,562 $ (1,750 ) $ 649,976 Held-to-Maturity (in thousands) Amortized Cost Gross Unrealized Gains Gross Unrealized Losses Fair Value State and political subdivisions $ 517 $ 0 $ 0 $ 517 Total held-to-maturity securities $ 517 $ 0 $ 0 $ 517 The amortized cost and fair value of securities at December 31, 2018 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 $ 219,358 $ 48 $ (1,468 ) $ 217,938 State and political subdivisions 126,280 633 (2,425 ) 124,488 U.S. government sponsored agency mortgage-backed securities 255,969 397 (5,547 ) 250,819 Other debt securities 507 0 (6 ) 501 Total available-for-sale securities $ 602,114 $ 1,078 $ (9,446 ) $ 593,746 Held-to-Maturity (in thousands) Amortized Cost Gross Unrealized Gains Gross Unrealized Losses Fair Value State and political subdivisions $ 649 $ 0 $ 0 $ 649 Total held-to-maturity securities $ 649 $ 0 $ 0 $ 649 The amortized cost and fair value of debt securities at September 30, 2019 by contractual maturity are shown below.

There was a pre-tax loss of $ thousand realized on calls of AFS securities consisting of a pre-tax gain of $ thousand and a pre-tax loss of $ thousand, and an unrealized gain of $ thousand from the fair market value adjustment of equity securities. During the three months ended September 30, 2018, there was a pre-tax loss of $ thousand realized on calls of AFS securities. During the nine months ended September 30, 2019, there was a net securities gain of $ thousand. There was a pre-tax gain of $ thousand realized on sales and calls of AFS securities consisting of a pre-tax gain of $ thousand and a pre-tax loss of $ thousand, and an unrealized gain of $ thousand from the fair market value adjustment of equity securities. During the nine months ended September 30, 2018, there was a combined loss of $ thousand realized on sales and calls of AFS securities, consisting of a pre-tax gain of $ thousand and a pre-tax loss of $ thousand. Equity Securities at Fair Value In 2008, Visa distributed shares of Visa Class B restricted stock to CTBI which, upon resolution of certain pending legal matters, will become unrestricted and convertible into Visa Class A shares. Following this distribution, significant concern existed about the ultimate realizable value of these shares, and because CTBI did not have a basis in the stock, the shares were previously not recorded as an asset on CTBI’s balance sheet. In recent years, the concern over the realizable value has stabilized, and in late 2017 and 2018, several sales of Visa Class B shares have occurred. While not traded in observable markets, these sales were reported by several financial institutions in various SEC 8-K and 10-K filings. In 2018, FASB issued a technical correction to its guidance regarding equity securities, ASC 321-10-35-2, allowing an entity to subsequently elect to record an equity security without a readily determinable fair value. In 2018, CTBI made the election permitted by ASC 321-10-35-2 to record its Visa Class B shares at fair value. On December 31, 2018, CTBI recorded a $ million gain on the recognition of the fair value of Visa Class B shares held in its portfolio. Equity securities at fair value as of September 30, 2019 were $ million, as a result of a fair market value increase in the third quarter 2019. The amortized cost of securities pledged as collateral, to secure public deposits and for other purposes, was $ million at September 30, 2019 and $ million at December 31, 2018. The amortized cost of securities sold under agreements to repurchase amounted to $ million at September 30, 2019 and $ million at December 31, 2018. CTBI evaluates its investment portfolio on a quarterly basis for impairment. The analysis performed as of September 30, 2019 indicates that all impairment is considered temporary, market and interest rate driven, and not credit-related. The percentage of total debt securities with unrealized losses as of September 30, 2019 was compared to as of December 31, 2018. The following tables provide the amortized cost, gross unrealized losses, and fair market value, aggregated by investment category and length of time the individual securities have been in a continuous unrealized loss position as of September 30, 2019 that are not deemed to be other-than-temporarily impaired. There were no held-to-maturity securities that were deemed to be impaired as of September 30, 2019. Available-for-Sale (in thousands) Amortized Cost Gross Unrealized Losses Fair Value Less Than 12 Months U.S. Treasury and government agencies $ 25,253 $ (153 ) $ 25,100 State and political subdivisions 8,358 (37 ) 8,321 U.S. government sponsored agency mortgage-backed securities 17,634 (70 ) 17,564 Other debt securities 12,303 (6 ) 12,297 Total <12 months temporarily impaired AFS securities 63,548 (266 ) 63,282 12 Months or More U.S. Treasury and government agencies 86,397 (466 ) 85,931 State and political subdivisions 0 0 0 U.S. government sponsored agency mortgage-backed securities 104,959 (1,018 ) 103,941 Other debt securities 0 0 0 Total ≥12 months temporarily impaired AFS securities 191,356 (1,484 ) 189,872 Total U.S. Treasury and government agencies 111,650 (619 ) 111,031 State and political subdivisions 8,358 (37 ) 8,321 U.S. government sponsored agency mortgage-backed securities 122,593 (1,088 ) 121,505 Other debt securities 12,303 (6 ) 12,297 Total temporarily impaired AFS securities $ 254,904 $ (1,750 ) $ 253,154 The analysis performed as of December 31, 2018 indicated that all impairment was considered temporary, market and interest rate driven, and not credit-related.

The contractual terms of those investments do not permit the issuer to settle the securities at a price less than par which will equal amortized cost at maturity. CTBI does not consider those investments to be other-than-temporarily impaired at September 30, 2019, because CTBI does not intend to sell the investments and it is not more likely than not that we will be required to sell the investments before recovery of their amortized cost, which may be maturity. State and Political Subdivisions The unrealized losses in securities of state and political subdivisions were caused by interest rate increases. The contractual terms of those investments do not permit the issuer to settle the securities at a price less than par which will equal amortized cost at maturity. CTBI does not consider those investments to be other-than-temporarily impaired at September 30, 2019, because CTBI does not intend to sell the investments before recovery of their amortized cost and it is not more likely than not that we will be required to sell the investments before recovery of their amortized cost, which may be maturity. U.S. Government Sponsored Agency Mortgage-Backed Securities The unrealized losses in U.S. government sponsored agency mortgage-backed securities were caused by interest rate increases. CTBI expects to recover the amortized cost basis over the term of the securities. CTBI does not consider those investments to be other-than-temporarily impaired at September 30, 2019, because (i) the decline in market value is attributable to changes in interest rates and not credit quality, (ii) CTBI does not intend to sell the investments, and (iii) it is not more likely than not we will be required to sell the investments before recovery of their amortized cost, which may be maturity. Other Debt Securities The unrealized losses in other debt securities were caused by interest rate increases. The contractual terms of those investments do not permit the issuer to settle the securities at a price less than par which will equal amortized cost at maturity. CTBI does not consider those investments to be other-than-temporarily impaired at September 30, 2019, because CTBI does not intend to sell the investments and it is not more likely than not that we will be required to sell the investments before recovery of their amortized cost, which may be maturity.

Loans [Abstract]
Loans	Note 4 – Loans Major classifications of loans, net of unearned income, deferred loan origination costs, and net premiums on acquired loans, are summarized as follows: (in thousands) September 30 2019 December 31 2018 Commercial construction $ 93,534 $ 82,715 Commercial secured by real estate 1,174,764 1,183,093 Equipment lease financing 651 1,740 Commercial other 388,532 377,198 Real estate construction 62,859 57,160 Real estate mortgage 722,632 722,417 Home equity 110,663 106,299 Consumer direct 149,500 144,289 Consumer indirect 511,650 533,727 Total loans $ 3,214,785 $ 3,208,638 CTBI has segregated and evaluates its loan portfolio through nine portfolio segments. 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. Commercial construction loans are for the purpose of erecting or rehabilitating buildings or other structures for commercial purposes, including any infrastructure necessary for development. Included in this category are improved property, land development, and tract development loans. The terms of these loans are generally short-term with permanent financing upon completion. Commercial real estate loans include loans secured by nonfarm, nonresidential properties, 1-4 family/multi-family properties, farmland, and other commercial real estate. These loans are originated based on the borrower’s ability to service the debt and secondarily based on the fair value of the underlying collateral. Equipment lease financing loans are fixed or variable leases for commercial purposes. Commercial other loans consist of commercial check loans, agricultural loans, receivable financing, floorplans, 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 real estate, equipment, or other assets, although such loans may be uncollateralized but guaranteed. Real estate construction loans are typically for owner-occupied properties. The terms of these loans are generally short-term with permanent financing upon completion. Residential real estate loans are a mixture of fixed rate and adjustable rate first and second lien residential mortgage loans. As a policy, CTBI holds adjustable rate loans and sells the majority of its fixed rate first lien mortgage loans into the secondary 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 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.

The risk characteristics of CTBI’s material portfolio segments are as follows: Commercial 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 loans are viewed primarily as cash flow loans and secondarily as loans secured by real estate. Commercial real estate 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. Commercial real estate loans may be more adversely affected by conditions in the real estate markets or in the general economy. Management monitors and evaluates commercial real estate loans based on collateral and risk grade criteria. Equipment lease financing is underwritten by our commercial lenders using the same underwriting standards as would be applied to a secured commercial loan requesting 100% financing. The pricing for equipment lease financing is comparable to that of borrowers with similar quality commercial credits with similar collateral. Maximum terms of equipment leasing are determined by the type and expected life of the equipment to be leased. Residual values are determined by appraisals or opinion letters from industry experts. Leases must be in conformity with our consolidated annual tax plan. 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. Commercial 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. 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 commercial loan portfolio based on rating category and payment activity, segregated by class of loans, as of September 30, 2019 and December 31, 2018: (in thousands) Commercial Construction Commercial Secured by Real Estate Equipment Leases Commercial Other Total September 30, 2019 Pass $ 88,034 $ 1,037,428 $ 651 $ 356,980 $ 1,483,093 Watch 2,527 55,119 0 13,737 71,383 OAEM 168 29,516 0 5,637 35,321 Substandard 2,805 52,616 0 12,030 67,451 Doubtful 0 85 0 148 233 Total $ 93,534 $ 1,174,764 $ 651 $ 388,532 $ 1,657,481 December 31, 2018 Pass $ 74,222 $ 1,038,309 $ 1,740 $ 327,431 $ 1,441,702 Watch 3,070 71,834 0 28,986 103,890 OAEM 1,594 19,734 0 5,735 27,063 Substandard 3,829 53,125 0 14,970 71,924 Doubtful 0 91 0 76 167 Total $ 82,715 $ 1,183,093 $ 1,740 $ 377,198 $ 1,644,746 The following tables present the credit risk profile of CTBI’s residential real estate and consumer loan portfolios based on performing or nonperforming status, segregated by class, as of September 30, 2019 and December 31, 2018: (in thousands) Real Estate Construction Real Estate Mortgage Home Equity Consumer Direct Consumer Indirect Total September 30, 2019 Performing $ 62,564 $ 712,734 $ 109,738 $ 149,429 $ 511,244 $ 1,545,709 Nonperforming (1) 295 9,898 925 71 406 11,595 Total $ 62,859 $ 722,632 $ 110,663 $ 149,500 $ 511,650 $ 1,557,304 December 31, 2018 Performing $ 57,132 $ 712,927 $ 105,576 $ 144,215 $ 533,221 $ 1,553,071 Nonperforming (1) 28 9,490 723 74 506 10,821 Total $ 57,160 $ 722,417 $ 106,299 $ 144,289 $ 533,727 $ 1,563,892 (1) A loan is considered nonperforming if it is 90 days or more past due and/or on nonaccrual. The total of consumer mortgage loans secured by real estate properties for which formal foreclosure proceedings are in process totaled $3.0 million at September 30, 2019 A loan is considered impaired, in accordance with the impairment accounting guidance (ASC 310-10-35-16), when based on current information and events, it is probable CTBI will be unable to collect all amounts due from the borrower in accordance with the contractual terms of the loan. Impaired loans include nonperforming commercial loans but also include loans modified in troubled debt restructurings where concessions have been granted to borrowers experiencing financial difficulties. These concessions could include a reduction in the interest rate on the loan, payment extensions, forgiveness of principal, forbearance, or other actions intended to maximize collection.

Included in certain loan categories of impaired loans are certain loans and leases that have been modified in a troubled debt restructuring, where economic concessions have been granted to borrowers who have experienced financial difficulties. These concessions typically result from our loss mitigation activities and could include reductions in the interest rate, payment extensions, forgiveness of principal, forbearance or other actions. Modifications of terms for our loans and their inclusion as troubled debt restructurings are based on individual facts and circumstances. Loan modifications that are included as troubled debt restructurings may involve either an increase or reduction of the interest rate, extension of the term of the loan, or deferral of principal and/or interest payments, regardless of the period of the modification. All of the loans identified as troubled debt restructuring were modified due to financial stress of the borrower. In order to determine if a borrower is experiencing financial difficulty, an evaluation is performed to determine the probability that the borrower will be in payment default on any of its debt in the foreseeable future without the modification. This evaluation is performed under CTBI’s internal underwriting policy. When we modify loans and leases in a troubled debt restructuring, we evaluate any possible impairment similar to other impaired loans based on the present value of expected future cash flows, discounted at the contractual interest rate of the original loan or lease agreement, or use the current fair value of the collateral, less selling costs for collateral dependent loans. If we determined that the value of the modified loan is less than the recorded investment in the loan (net of previous charge-offs, deferred loan fees or costs and unamortized premium or discount), impairment is recognized through an allowance estimate or a charge-off to the allowance. In periods subsequent to modification, we evaluate all troubled debt restructuring, including those that have payment defaults, for possible impairment and recognize impairment through the allowance. During 2019, certain loans were modified in troubled debt restructurings, where economic concessions were granted to borrowers consisting of reductions in the interest rates, payment extensions, forgiveness of principal, and forbearances. Presented below, segregated by class of loans, are troubled debt restructurings that occurred during the three and nine months ended September 30, 2019 and 2018 and the year ended December 31, 2018: Three Months Ended September 30, 2019 (in thousands) Number of Loans Term Modification Rate Modification Combination Post- Modification Outstanding Balance Commercial: Commercial secured by real estate 3 $ 270 $ 0 $ 0 $ 270 Commercial other 2 32 0 0 32 Total troubled debt restructurings 5 $ 302 $ 0 $ 0 $ 302 Nine Months Ended September 30, 2019 (in thousands) Number of Loans Term Modification Rate Modification Combination Post- Modification Outstanding Balance Commercial: Commercial secured by real estate 13 $ 4,784 $ 0 $ 679 $ 5,463 Commercial other 13 1,292 0 140 1,432 Residential: Real estate mortgage 2 463 0 243 706 Total troubled debt restructurings 28 $ 6,539 $ 0 $ 1,062 $ 7,601 Year Ended December 31, 2018 (in thousands) Number of Loans Term Modification Rate Modification Combination Post- Modification Outstanding Balance Commercial: Commercial construction 5 $ 2,182 $ 0 $ 15 $ 2,197 Commercial secured by real estate 24 4,004 0 1,383 5,387 Commercial other 8 465 0 0 465 Residential: Real estate mortgage 3 264 0 704 968 Total troubled debt restructurings 40 $ 6,915 $ 0 $ 2,102 $ 9,017 Three Months Ended September 30, 2018 (in thousands) Number of Loans Term Modification Rate Modification Combination Post- Modification Outstanding Balance Commercial: Commercial secured by real estate 6 $ 2,028 $ 0 $ 400 $ 2,428 Residential: Real estate mortgage 1 264 0 0 264 Total troubled debt restructurings 7 $ 2,292 $ 0 $ 400 $ 2,692 Nine Months Ended September 30, 2018 (in thousands) Number of Loans Term Modification Rate Modification Combination Post- Modification Outstanding Balance Commercial: Commercial construction 4 $ 443 $ 0 $ 15 $ 458 Commercial secured by real estate 23 4,587 0 1,383 5,970 Commercial other 8 465 0 0 465 Residential: Real estate mortgage 1 264 0 0 264 Total troubled debt restructurings 36 $ 5,759 $ 0 $ 1,398 $ 7,157 No charge-offs have resulted from modifications for any of the presented periods. We had $ thousand in commitments to extend additional credit on loans that were considered troubled debt restructurings at September 30,2019. 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.

Leases [Abstract]
Leases	Note 6 – Leases Effective January 1, 2019, CTBI adopted ASU No. 2016-02, Leases, CTBI has operating leases for banking and ATM locations. These leases have remaining lease terms of 1 year to 45 years, some of which include options to extend the leases for up to 5 years. We evaluated the original lease terms for each operating lease, some of which include options to extend the leases for up to 5 years, using hindsight. These options, some of which include variable costs related to rent escalations based on recent financial indices, such as the Consumer Price Index, where CTBI estimates future rent increases, are included in the calculation of the lease liability and right-of-use asset when management determines it is reasonably certain the option will be exercised. CTBI determines this on each lease by considering all relevant contract-based, asset-based, market-based, and entity-based economic factors. Right-of-use assets and lease liabilities are recognized at lease commencement based on the present value of the remaining lease payments using a discount rate that represents our incremental borrowing rate on a collateralized basis, over a similar term at the lease commencement date. Right-of-use assets are further adjusted for prepaid rent, lease incentives, and initial direct costs, if any.

Repurchase Agreements [Abstract]
Repurchase Agreements	Note 8 – 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 $262.8 million and $285.2 million at September 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 September 30, 2019 and December 31, 2018 is presented in the following tables: September 30, 2019 Remaining Contractual Maturity of the Agreements (in thousands) Overnight and Up to 30 days 30-90 days Greater Than Total Repurchase agreements and repurchase-to-maturity transactions: U.S. Treasury and government agencies $ 15,873 $ 11,643 $ 0 $ 48,936 $ 76,452 State and political subdivisions 51,888 2,691 0 9,951 64,530 U.S. government sponsored agency mortgage-backed securities 35,765 16,666 0 35,342 87,773 Total $ 103,526 $ 31,000 $ 0 $ 94,229 $ 228,755 December 31, 2018 Remaining Contractual Maturity of the Agreements (in thousands) Overnight and Up to 30 days 30-90 days Greater Than Total Repurchase agreements and repurchase-to-maturity transactions: U.S. Treasury and government agencies $ 25,346 $ 0 $ 2,548 $ 60,699 $ 88,593 State and political subdivisions 58,864 0 2,995 10,384 72,243 U.S. government sponsored agency mortgage-backed securities 22,076 0 1,877 47,923 71,876 Total $ 106,286 $ 0 $ 7,420 $ 119,006 $ 232,712

Fair Market Value of Financial Assets and Liabilities [Abstract]
Fair Market Value of Financial Assets and Liabilities	Note 9 – 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 September 30, 2019 and December 31, 2018 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 September September 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 September and December 31, 2018 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. Transfers between Levels There were no transfers between Levels 1, 2, and 3 as of September Level 3 Reconciliation Following is a reconciliation of the beginning and ending balances of recurring fair value measurements recognized in the accompanying balance sheet using significant unobservable (Level 3) inputs for the three and nine months ended September 30, 2019 and 2018 : (in thousands) Three Months Ended September 30, 2019 Three Months Ended September 30, 2018 Equity Securities at Fair Value Mortgage Servicing Rights Equity Securities at Fair Value Mortgage Servicing Rights Beginning balance $ 1,727 $ 3,119 $ 0 $ 3,772 Total unrealized gains (losses) Included in net income 16 (325 ) 0 45 Issues 0 139 0 118 Settlements 0 (29 ) 0 (120 ) Ending balance $ 1,743 $ 2,904 $ 0 $ 3,815 Total gains (losses) for the period included in net income attributable to the change in unrealized gains or losses related to assets still held at the reporting date $ 16 $ (325 ) $ 0 $ 45 (in thousands) Nine Months Ended September 30, 2019 Nine Months Ended September 30, 2018 Equity Securities at Fair Value Mortgage Servicing Rights Equity Securities at Fair Value Mortgage Servicing Rights Beginning balance $ 1,173 $ 3,607 $ 0 $ 3,484 Total unrealized gains (losses) Included in net income 570 (907 ) 0 341 Issues 0 446 0 329 Settlements 0 (242 ) 0 (339 ) Ending balance $ 1,743 $ 2,904 $ 0 $ 3,815 Total gains (losses) for the period included in net income attributable to the change in unrealized gains or losses related to assets still held at the reporting date $ 570 $ (907 ) $ 0 $ 341 Realized and unrealized gains and losses for items reflected in the table above are included in net income in the consolidated statements of income as follows: Noninterest Income Three Months Ended September 30 Nine Months Ended September 30 (in thousands) 2019 2018 2019 2018 Total gains (losses) $ (338 ) $ (75 ) $ (579 ) $ 2 Nonrecurring Measurements The following tables present the fair value measurements of assets recognized in the accompanying balance sheets measured at fair value on a nonrecurring basis as of September 30, 2019 and December 31, 2018 and indicate the level within the fair value hierarchy of the valuation techniques.

For assets classified within Level 3 of the fair value hierarchy, the process used to develop the reported fair value is described below. Impaired Loans (Collateral Dependent) The estimated fair value of collateral-dependent impaired loans is based on the appraised fair value of the collateral, less estimated cost to sell. Collateral-dependent impaired 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 impaired under ASC 310-35, Impairment of a Loan, September and for the quarter ended September Year-to-date fair value adjustments were for the nine months ended September for the year ended December and for the nine months ended September Other Real Estate Owned In accordance with the provisions of ASC 360, Property, Plant, and Equipment, September September Year-to-date fair value adjustments on other real estate owned disclosed above were for the nine months ended September for the year ended December and for the nine months ended September 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 September 30, 2019 and December 31, 2018. (in thousands) Quantitative Information about Level 3 Fair Value Measurements Fair Value at September 30, 2019 Valuation Technique(s) Unobservable Input Range (Weighted Average) Equity securities at fair value $1,743 Discount cash flows, computer pricing model Discount rate 8.0% - 12.0% (10.0%) Conversion date Dec 2022 Dec 2026 ( Dec 2024 Mortgage servicing rights $2,904 Discount cash flows, computer pricing model Constant prepayment rate 0.0%% - 25.6% (14.6%) Probability of default 0.0% - 100.0% (2.5%) Discount rate 10.0% - 11.5% (10.1%) Impaired loans (collateral-dependent) $1,235 Market comparable properties Marketability discount (0.1%) - 99.0% (44.0%) Other real estate owned $5,022 Market comparable properties Comparability adjustments 9.5% - 95.0% (15.2%) (in thousands) Quantitative Information about Level 3 Fair Value Measurements Fair Value at December 31, 2018 Valuation Technique(s) Unobservable Input Range (Weighted Average) Equity securities at fair value $1,173 Discount cash flows, computer pricing model Discount rate 8.0% - 12.0% (10.0%) Conversion date Dec 2022 Dec 2026 ( Dec 2024 Mortgage servicing rights $3,607 Discount cash flows, computer pricing model Constant prepayment rate 7.0% - 28.1% (9.5%) Probability of default 0.0% - 100.0% (2.6%) Discount rate 10.0% - 11.5% (10.1%) Impaired loans (collateral-dependent) $747 Market comparable properties Marketability discount 0.0% - 95.1% (41.5%) Other real estate owned $6,500 Market comparable properties Comparability adjustments 6.0% - 47.6% (14.9%) Sensitivity of Significant Unobservable Inputs The following is a discussion of the sensitivity of significant unobservable inputs, the interrelationships between those inputs and other unobservable inputs used in recurring fair value measurement and of how those inputs might magnify or mitigate the effect of changes in the unobservable inputs on the fair value measurement. Equity Securities at Fair Value Fair market value for equity securities is derived based on unobservable inputs, such as the discount rate, quarterly dividend payments 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 0.4057 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 September 30, 2019 and indicates the level within the fair value hierarchy of the valuation techniques. In accordance with the prospective adoption of ASU 2016-01, the fair values as of September 30, 2019 were measured using an exit price notion.

New Accounting Standards	New Accounting Standards ➢ Leases Leases (Topic 842). In August 2018, the FASB issued ASU 2018-11, Leases (Topic 842): Targeted Improvements. This ASU is intended to reduce costs and ease implementation of the leases standard for financial statement preparers. ASU 2018-11 provides a new transition method and a practical expedient for separating components of a contract. Transition: Comparative Reporting at Adoption The amendments in ASU 2018-11 provide entities with an additional (and optional) transition method to adopt the new leases standard. Under this new transition method, an entity initially applies the new leases standard at the adoption date and recognizes a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption consistent with preparers’ requests. Consequently, an entity’s reporting for the comparative periods presented in the financial statements in which it adopts the new leases standard will continue to be in accordance with current GAAP in Topic 840, Leases Separating Components of a Contract The amendments in ASU 2018-11 provide lessors with a practical expedient, by class of underlying asset, to not separate non-lease components from the associated lease component and, instead, to account for those components as a single component if the non-lease components otherwise would be accounted for under the new revenue guidance (Topic 606) and both of the following are met: • The timing and pattern of transfer of the non-lease component(s) and associated lease component are the same. • The lease component, if accounted for separately, would be classified as an operating lease. An entity electing this practical expedient (including an entity that accounts for the combined component entirely in Topic 606) is required to disclose certain information, by class of underlying asset, as specified in the ASU. We elected the optional transition method of the modified retrospective approach provided in ASU 2018-11 which was applied on January 1, 2019. CTBI also elected certain relief options offered in ASU 2016-02, including the package of practical expedients, the option not to separate lease and non-lease components, and instead to account for them as a single lease component for all classes of assets, the hindsight practical expedient to allow entities to use hindsight when determining lease term and impairment of right-of-use assets, and the option not to recognize right-of-use assets and lease liabilities that arise from short-term leases (i.e., leases with terms of twelve months or less). Refer to note 6, Leases, below for further information regarding the impact of adoption. ➢ Accounting for Credit Losses Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. For purchased financial assets with a more-than-insignificant amount of credit deterioration since origination (“PCD assets”) that are measured at amortized cost, the initial allowance for credit losses is added to the purchase price rather than being reported as a credit loss expense. Subsequent changes in the allowance for credit losses on PCD assets are recognized through the statement of income as a credit loss expense. Credit losses relating to available-for-sale debt securities will be recorded through an allowance for credit losses rather than as a direct write-down to the security. ASU 2016-13 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. CTBI has an implementation team working through the provisions of ASU 2016-13 including assessing the impact on its accounting and disclosures. The team has established the historical data that will be available and has identified the potential loan segments to be analyzed. The team has determined the portfolio methodologies and relevant economic factors to be utilized and will begin running parallel with its current model as part of the monthly fourth quarter 2019 loan portfolio analysis. ➢ Simplifying the Test for Goodwill Impairment Intangibles – Goodwill and Other (Topic 350) – Simplifying the Test for Goodwill Impairment ➢ Changes to the Disclosure Requirements for Fair Value Measurement Fair Value Measurement (Topic 820)—Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement Removals The following disclosure requirements were removed from Topic 820: • The amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy • The policy for timing of transfers between levels • The valuation processes for Level 3 fair value measurements Modifications The following disclosure requirements were modified in Topic 820: • For investments in certain entities that calculate net asset value, an entity is required to disclose the timing of liquidation of an investee’s assets and the date when restrictions from redemption might lapse only if the investee has communicated the timing to the entity or announced the timing publicly; and • The amendments clarify that the measurement uncertainty disclosure is to communicate information about the uncertainty in measurement as of the reporting date. Additions The following disclosure requirements were added to Topic 820: • The changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period; and • The range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. For certain unobservable inputs, an entity may disclose other quantitative information (such as the median or arithmetic average) in lieu of the weighted average if the entity determines that other quantitative information would be a more reasonable and rational method to reflect the distribution of unobservable inputs used to develop Level 3 fair value measurements. In addition, the amendments eliminate “at a minimum” from the phrase “an entity shall disclose at a minimum” to promote the appropriate exercise of discretion by entities when considering fair value measurement disclosures and to clarify that materiality is an appropriate consideration of entities and their auditors when evaluating disclosure requirements. CTBI plans to adopt ASU 2018-13 effective January 1, 2020 with minimal changes to our current reporting. ➢ Accounting for Costs of Implementing a Cloud Computing Service Agreement Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract The ASU aligns the following requirements for capitalizing implementation costs: • Those incurred in a hosting arrangement that is a service contract, and • Those incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). This ASU will be effective beginning January 1, 2020. We do not anticipate a significant impact to our consolidated financial statements.
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. 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. When the fair value of a security is below its amortized cost, and depending on the length of time the condition exists and the extent the fair market value is below amortized cost, additional analysis is performed to determine whether an other than temporary impairment condition exists. Available-for-sale and held-to-maturity securities are analyzed quarterly for possible other than temporary impairment. The analysis considers (i) whether we have the intent to sell our securities prior to recovery and/or maturity and (ii) whether it is more likely than not that we will not have to sell our securities prior to recovery and/or maturity. Often, the information available to conduct these assessments is limited and rapidly changing, making estimates of fair value subject to judgment. If actual information or conditions are different than estimated, the extent of the impairment of the security may be different than previously estimated, which could have a material effect on CTBI’s results of operations and financial condition. Subsequent to the January 1, 2018 effective date of ASU 2016-01, ASC 320 applies only to debt securities and 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. An election can be made, as permitted by ASC 321-10-35-2, to subsequently measure an equity security without a readily determinable fair value, at fair value. Equity securities held by CTBI include securities without readily determinable fair values. CTBI has elected to account for these securities at fair value. 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 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 Loan and Lease Losses	Allowance for Loan and Lease Losses – We maintain an allowance for loan and lease losses (“ALLL”) at a level that is appropriate to cover estimated credit losses on individually evaluated loans determined to be impaired, 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 ALLL. We utilize an internal risk grading system for commercial credits. Those larger commercial credits that exhibit probable or observed credit weaknesses are subject to individual review. The borrower’s cash flow, adequacy of collateral coverage, and other options available to CTBI, including legal remedies, are evaluated. The review of individual loans includes those loans that are impaired as defined by ASC 310-10-35, Impairment of a Loan A loan is considered impaired when, based on current information and events, it is probable that CTBI will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. Impairment is measured on a loan-by-loan basis for commercial and construction loans by either the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price, or the fair value of the collateral if the loan is collateral dependent. Homogenous loans, such as consumer installment, residential mortgages, and home equity lines are not individually risk graded. The associated ALLL for these loans is measured under ASC 450, Contingencies 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 or a specific reserve equal to the difference between book value of the loan and the fair value assigned to the collateral is created until such time as the loan is foreclosed. 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 90 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. We use twelve rolling quarters for our historical loss rate analysis. Factors that we consider include delinquency trends, current economic conditions and trends, strength of supervision and administration of the loan portfolio, levels of underperforming loans, level of recoveries to prior year’s charge-offs, trends in loan losses, industry concentrations and their relative strengths, amount of unsecured loans, and underwriting exceptions. Management continually reevaluates the other subjective factors included in its ALLL analysis.
Other Real Estate Owned	Other Real Estate Owned
Income Taxes	Income Taxes – Income tax expense is based on the taxes due on the consolidated tax return plus deferred taxes based on the expected future tax benefits and consequences of temporary differences between carrying amounts and tax bases of assets and liabilities, using enacted tax rates. Any interest and penalties incurred in connection with income taxes are recorded as a component of income tax expense in the consolidated financial statements. During the three and nine months ended September 30, 2019 and 2018, CTBI has not recognized a significant amount of interest expense or penalties in connection with income taxes. As a bank doing business in Kentucky, CTB is subject to a capital-based Kentucky bank franchise tax and exempt from Kentucky corporate income tax. However, in March 2019, Kentucky enacted HB354, which will transition CTB from the bank franchise tax to a corporate income tax beginning January 1, 2021. The current Kentucky corporate income tax rate is . As of March 31, 2019, CTBI recorded a deferred tax liability, net of the federal benefit, of $ million due to the enactment of HB354. In April 2019, Kentucky enacted HB458. HB458 allows for combined state income tax filing with CTBI, CTB, and CTIC. CTBI had previously filed a separate company return and generated net operating losses, in which it had maintained a valuation allowance against the related deferred tax asset. HB458 also allows for certain net operating losses to be utilized on a combined return. CTBI expects to file a combined return, beginning in 2021, and to utilize these previously generated losses. The tax benefit recorded in the second quarter 2019 to reverse the valuation allowance on the deferred tax asset for these losses was $ million.

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.
