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 accruals) necessary, to present fairly the condensed consolidated financial position as of June 30, 2015, the results of operations for the three and six months ended June 30, 2015 and 2014, and the cash flows for the six months ended June, 2015 and 2014. 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 six months ended June 30, 2015 and 2014, and the cash flows for the six months ended June 30, 2015 and 2014, are not necessarily indicative of the results to be expected for the full year. The condensed consolidated balance sheet as of December 31, 2014 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, 2014, included in our annual report on Form 10-K. Principles of Consolidation – Reclassifications – All share data has been adjusted for the 10% stock dividend issued on June 2, 2014. New Accounting Standards Ø Investments—Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Qualified Affordable Housing Projects Ø Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure Receivables—Troubled Debt Restructurings by Creditors (Subtopic 310-40): Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure Ø Elimination of Extraordinary Reporting Income Statement – Extraordinary and Unusual Items (Subtopic 225-20): Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items. Ø Intangibles – Goodwill and Other – Internal-Use Software Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40) 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 Investment 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 securities are computed by specific identification for all securities except for shares in mutual funds, which are computed by average cost. 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 the CTBI's results of operations and financial condition. 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 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 310-35, 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 non-accrual 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, a charge off is taken, if necessary, in order that the remaining balance reflects the fair value estimated less costs to sell of the collateral then transferred to other real estate owned or other repossessed assets. 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. Based upon management's judgment, "best case," "worst case," and "most likely" scenarios are determined. The total of each of these weighted factors is then applied against the applicable portion of the portfolio and the ALLL is adjusted accordingly to approximate the most likely scenario. Management continually reevaluates the other subjective factors included in its ALLL analysis. Other Real Estate Owned Income Taxes CTBI is currently under IRS examination of its 2013 corporate income tax return. Management does not expect that the results of the examination will have a material effect on our financial condition. While management believes our tax positions are appropriate, the IRS could challenge our positions as a part of this examination.

Stock-Based Compensation [Abstract]
Stock-Based Compensation	Note 2 – Stock-Based Compensation CTBI's compensation expense related to stock option grants was $10 thousand and $2 thousand, respectively, for the three months ended June 30, 2015 and 2014, and $18 thousand and $6 thousand, respectively, for the six months ended June 30, 2015 and 2014. Restricted stock expense for the three months ended June 30, 2015 and 2014 was $180 thousand and $151 thousand, respectively, including $20 thousand and $30 thousand in dividends paid for each period. Restricted stock expense for the six months ended June 30, 2015 and 2014 was $369 thousand and $338 thousand, respectively, including $39 thousand and $60 thousand in dividends. As of June 30, 2015, there was a total of $0.2 million 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 4.3 years and a total of $0.8 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 2.0 years. There were no shares of restricted stock granted during the three months ended June 30, 2015 and 2014. There were 10,582 and 4,561 shares of restricted stock granted during the six months ended June 30, 2015 and 2014, respectively. The restrictions on the restricted stock lapse ratably over four years or in the event of a change in control of CTBI or the death of the participant. In the event of the disability of the participant, the restrictions will lapse on a pro rata basis. The Compensation Committee of the Board of Directors will have discretion to review and revise restrictions applicable to a participant's restricted stock in the event of the participant's retirement. There were no options granted to purchase shares of CTBI common stock during the three months ended June 30, 2015. There were 20,000 options granted during the six months ended June 30, 2015. No options were granted during the three or six months ended June 30, 2014. The fair value of options granted during the six months ended June, 2015, were established at the date of grant using a Black-Scholes option pricing model with the weighted average assumptions as follows: Six Months Ended June 30 2015 Expected dividend yield 3.72 % Risk-free interest rate 1.54 % Expected volatility 30.77 % Expected term (in years) 7.0 Weighted average fair value of options $ 6.60

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.

As of June 30, 2014, there was a net loss of $111 thousand. The amortized cost of securities pledged as collateral, to secure public deposits and for other purposes, was $227.3 million at June 30, 2015 and $267.1 million at December 31, 2014. The amortized cost of securities sold under agreements to repurchase amounted to $272.6 million at June 30, 2015 and $280.9 million at December 31, 2014. CTBI evaluates its investment portfolio on a quarterly basis for impairment. The analysis performed as of June 30, 2015 indicates that all impairment is considered temporary, market and interest rate driven, and not credit-related. The percentage of total investments with unrealized losses as of June 30, 2015 was 43.6% compared to 44.1% as of December 31, 2014. 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 June 30, 2015 that are not deemed to be other-than-temporarily impaired.

The contractual terms of those investments do not permit the issuer to settle the securities at a price less than amortized cost. CTBI does not consider those investments to be other-than-temporarily impaired at June 30, 2015, 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 at 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 amortized cost. CTBI does not consider those investments to be other-than-temporarily impaired at June 30, 2015, because CTBI does not intend to sell the investments before recovery of their amortized cost, which may be at 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 June 30, 2015, 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 at maturity. CRA Investment Funds CTBI's CRA investment funds consist of investments in fixed income mutual funds ($24.8 million of the total fair value and $203 thousand of the total unrealized losses in common stock investments). The severity of the impairment (fair value is approximately 0.8% less than cost) and the duration of the impairment correlates with the decline in long-term interest rates in 2015. CTBI evaluated the near-term prospects of these funds in relation to the severity and duration of the impairment. Based on that evaluation, CTBI does not consider those investments to be other-than-temporarily impaired at June 30, 2015. The analysis performed as of December 31, 2014 indicated that all impairment was considered temporary, market and interest rate driven, and not credit-related. 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 December 31, 2014 that are not deemed to be other-than-temporarily impaired.

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) June 30 2015 December 31 2014 Commercial construction $ 111,218 $ 121,942 Commercial secured by real estate 978,412 948,626 Equipment lease financing 9,859 10,344 Commercial other 363,909 352,048 Real estate construction 57,914 62,412 Real estate mortgage 707,582 712,465 Home equity 88,113 88,335 Consumer direct 121,620 122,136 Consumer indirect 354,204 315,516 Total loans $ 2,792,831 $ 2,733,824 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, variable, and tax exempt 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 primarily fixed 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 $2.0 million at June 30, 2015 and $2.3 million at December 31, 2014, respectively.

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 recourse agreements with the Bank. 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: Ø Pass Ø Watch Ø Other assets especially mentioned (OAEM) Ø Substandard Ø Doubtful The following table presents the credit risk profile of CTBI's commercial loan portfolio based on rating category and payment activity, segregated by class of loans, as of June 30, 2015 and December 31, 2014: (in thousands) Commercial Construction Commercial Secured by Real Estate Equipment Leases Commercial Other Total June 30, 2015 Pass $ 91,970 $ 866,899 $ 9,859 $ 323,470 $ 1,292,198 Watch 7,954 70,847 0 32,858 111,659 OAEM 1,939 8,998 0 949 11,886 Substandard 5,656 27,750 0 5,756 39,162 Doubtful 3,699 3,918 0 876 8,493 Total $ 111,218 $ 978,412 $ 9,859 $ 363,909 $ 1,463,398 December 31, 2014 Pass $ 101,314 $ 834,751 $ 10,344 $ 307,270 $ 1,253,679 Watch 9,857 69,123 0 36,114 115,094 OAEM 934 10,973 0 881 12,788 Substandard 5,647 27,901 0 5,772 39,320 Doubtful 4,190 5,878 0 2,011 12,079 Total $ 121,942 $ 948,626 $ 10,344 $ 352,048 $ 1,432,960 The following table presents the credit risk profile of the CTBI's residential real estate and consumer loan portfolios based on performing or nonperforming status, segregated by class, as of June 30, 2015 and December 31, 2014: (in thousands) Real Estate Construction Real Estate Mortgage Home Equity Consumer Direct Consumer Indirect Total June 30, 2015 Performing $ 57,324 $ 694,580 $ 87,505 $ 121,500 $ 353,945 $ 1,314,854 Nonperforming (1) 590 13,002 608 120 259 14,579 Total $ 57,914 $ 707,582 $ 88,113 $ 121,620 $ 354,204 $ 1,329,433 December 31, 2014 Performing $ 61,427 $ 698,210 $ 87,544 $ 121,995 $ 315,131 $ 1,284,307 Nonperforming (1) 985 14,255 791 141 385 16,557 Total $ 62,412 $ 712,465 $ 88,335 $ 122,136 $ 315,516 $ 1,300,864 (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 $6.3 million at June 30, 2015 compared to $5.9 million at December 31, 2014. A loan is considered impaired, in accordance with the impairment accounting guidance, 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. The following tables present impaired loans, the average investment in impaired loans, and interest income recognized on impaired loans for the periods ended June 30, 2015, December 31, 2014, and June 30, 2014: June 30, 2015 (in thousands) Recorded Balance Unpaid Contractual Principal Balance Specific Allowance Loans without a specific valuation allowance: Commercial construction $ 5,211 $ 5,211 $ 0 Commercial secured by real estate 29,951 31,340 0 Commercial other 7,262 8,898 0 Real estate mortgage 1,185 1,185 0 Loans with a specific valuation allowance: Commercial construction 3,500 3,500 719 Commercial secured by real estate 2,377 2,560 529 Commercial other 687 809 215 Totals: Commercial construction 8,711 8,711 719 Commercial secured by real estate 32,328 33,900 529 Commercial other 7,949 9,707 215 Real estate mortgage 1,185 1,185 0 Total $ 50,173 $ 53,503 $ 1,463 Three Months Ended Six Months Ended June 30, 2015 June 30, 2015 (in thousands) Average Investment in Impaired Loans *Interest Income Recognized Average Investment in Impaired Loans *Interest Income Recognized Loans without a specific valuation allowance: Commercial construction $ 5,266 $ 68 $ 5,282 $ 119 Commercial secured by real estate 30,366 359 30,179 669 Commercial other 7,367 67 10,118 128 Real estate mortgage 1,186 12 1,044 24 Loans with a specific valuation allowance: Commercial construction 3,796 0 3,846 0 Commercial secured by real estate 2,452 0 2,946 1 Commercial other 729 0 794 0 Totals: Commercial construction 9,062 68 9,128 119 Commercial secured by real estate 32,818 359 33,125 670 Commercial other 8,096 67 10,912 128 Real estate mortgage 1,186 12 1,044 24 Total $ 51,162 $ 506 $ 54,209 $ 941 December 31, 2014 (in thousands) Recorded Balance Unpaid Contractual Principal Balance Specific Allowance Average Investment in Impaired Loans *Interest Income Recognized Loans without a specific valuation allowance: Commercial construction $ 5,653 $ 5,654 $ 0 $ 5,415 $ 205 Commercial secured by real estate 31,639 33,268 0 34,650 1,180 Commercial other 13,069 14,597 0 15,663 783 Real estate mortgage 1,277 1,277 0 1,507 53 Loans with a specific valuation allowance: Commercial construction 3,974 3,974 734 4,216 0 Commercial secured by real estate 2,718 2,876 827 4,376 11 Commercial other 738 862 181 531 1 Totals: Commercial construction 9,627 9,628 734 9,631 205 Commercial secured by real estate 34,357 36,144 827 39,026 1,191 Commercial other 13,807 15,459 181 16,194 784 Real estate mortgage 1,277 1,277 0 1,507 53 Total $ 59,068 $ 62,508 $ 1,742 $ 66,358 $ 2,233 June 30, 2014 (in thousands) Recorded Balance Unpaid Contractual Principal Balance Specific Allowance Loans without a specific valuation allowance: Commercial construction $ 5,270 $ 5,271 $ 0 Commercial secured by real estate 33,504 34,523 0 Commercial other 16,947 18,527 0 Real estate mortgage 1,865 1,865 0 Loans with a specific valuation allowance: Commercial construction 4,285 4,285 734 Commercial secured by real estate 3,968 4,272 1,077 Commercial other 339 463 84 Totals: Commercial construction 9,555 9,556 734 Commercial secured by real estate 37,472 38,795 1,077 Commercial other 17,286 18,990 84 Real estate mortgage 1,865 1,865 0 Total $ 66,178 $ 69,206 $ 1,895 Three Months Ended Six Months Ended June 30, 2014 June 30, 2014 (in thousands) Average Investment in Impaired Loans *Interest Income Recognized Average Investment in Impaired Loans *Interest Income Recognized Loans without a specific valuation allowance: Commercial construction $ 5,291 $ 78 $ 5,366 $ 128 Commercial secured by real estate 33,687 332 35,051 597 Commercial other 17,362 257 15,843 371 Real estate mortgage 1,866 22 1,445 32 Loans with a specific valuation allowance: Commercial construction 4,285 0 4,299 0 Commercial secured by real estate 3,973 0 4,330 4 Commercial other 353 0 396 0 Totals: Commercial construction 9,576 78 9,665 128 Commercial secured by real estate 37,660 332 39,381 601 Commercial other 17,715 257 16,239 371 Real estate mortgage 1,866 22 1,445 32 Total $ 66,817 $ 689 $ 66,730 $ 1,132 *Cash basis interest is substantially the same as interest income recognized. 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 2015, 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 six months ended June 30, 2015 and 2014 and the year ended December 31, 2014: Three Months Ended June 30, 2015 (in thousands) Number of Loans Term Modification Rate Modification Combination Post-Modification Outstanding Balance Commercial: Commercial secured by real estate 4 $ 317 $ 0 $ 0 $ 317 Commercial other 1 18 0 0 18 Residential: Real estate mortgage 1 0 0 290 290 Total troubled debt restructurings 6 $ 335 $ 0 $ 290 $ 625 Six Months Ended June 30, 2015 (in thousands) Number of Loans Term Modification Rate Modification Combination Post-Modification Outstanding Balance Commercial: Commercial secured by real estate 8 $ 607 $ 0 $ 0 $ 607 Commercial other 3 54 0 0 54 Residential: Real estate mortgage 1 0 0 290 290 Total troubled debt restructurings 12 $ 661 $ 0 $ 290 $ 951 Three Months Ended June 30, 2014 (in thousands) Number of Loans Term Modification Rate Modification Combination Post-Modification Outstanding Balance Commercial: Commercial secured by real estate 1 $ 106 $ 0 $ 0 $ 106 Commercial other 1 20 0 0 20 Residential: Real estate mortgage 2 0 0 849 849 Total troubled debt restructurings 4 $ 126 $ 0 $ 849 $ 975 Six Months Ended June 30, 2014 (in thousands) Number of Loans Term Modification Rate Modification Combination Post-Modification Outstanding Balance Commercial: Commercial secured by real estate 3 $ 231 $ 0 $ 0 $ 231 Commercial other 3 61 0 0 61 Residential: Real estate mortgage 2 0 0 849 849 Total troubled debt restructurings 8 $ 292 $ 0 $ 849 $ 1,141 Year Ended December 31, 2014 (in thousands) Number of Loans Term Modification Rate Modification Combination Post-Modification Outstanding Balance Commercial: Commercial construction 1 $ 7 $ 0 $ 0 $ 7 Commercial secured by real estate 11 5,707 0 68 5,775 Commercial other 8 1,268 0 0 1,268 Residential: Real estate mortgage 2 0 0 848 848 Total troubled debt restructurings 22 $ 6,982 $ 0 $ 916 $ 7,898 No charge-offs have resulted from modifications for any of the presented periods. 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 generally considers a loan in default when it is 90 days or more past due or transferred to nonaccrual.

Repurchase Agreements [Abstract]
Repurchase Agreements	Note 7 – 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 $275.3 million and $283.3 million at June 30, 2015 and December 31, 2014, respectively. 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 June 30, 2015 and December 31, 2014 is presented in the following tables: June 30, 2015 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 $ 18,283 $ 4,600 $ 13,063 $ 11,171 $ 47,117 State and political subdivisions 61,151 3,937 1,724 7,266 74,078 U.S. government sponsored agency mortgage-backed securities 33,429 13,463 21,029 52,660 120,581 Total $ 112,863 $ 22,000 $ 35,816 $ 71,097 $ 241,776 December 31, 2014 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 $ 6,790 $ 1,000 $ 6,834 $ 14,076 $ 28,700 State and political subdivisions 59,451 0 1,839 12,474 73,764 U.S. government sponsored agency mortgage-backed securities 39,315 0 15,871 77,536 132,722 Total $ 105,556 $ 1,000 $ 24,544 $ 104,086 $ 235,186

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 pricing 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 June 30, 2015 and December 31, 2014 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 at fair value as of June 30, 2015 and December 31, 2014. There have been no significant changes in the valuation techniques during the quarter ended June 30, 2015. 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 and CTBI's CRA investment funds 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, and U.S. government sponsored agency mortgage-backed 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. As of June 30, 2015, CTBI does not own any securities classified as Level 3 inputs. 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. 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 June 30, 2015. 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 six months ended June 30, 2015 and 2014: Mortgage Servicing Rights Three Months Ended Six Months Ended June 30 June 30 (in thousands) 2015 2014 2015 2014 Beginning balance $ 2,797 $ 3,258 $ 2,968 $ 3,424 Total recognized gains (losses) Included in net income 446 (166 ) 285 (292 ) Issues 213 82 297 145 Settlements (221 ) (112 ) (315 ) (215 ) Ending balance $ 3,235 $ 3,062 $ 3,235 $ 3,062 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 $ 446 $ (166 ) $ 285 $ (292 ) Realized and unrealized gains and losses for items reflected in the tables above are included in net income in the consolidated statements of income as follows: Noninterest Income Three Months Ended Six Months Ended June 30 June 30 (in thousands) 2015 2014 2015 2014 Total gains (losses) $ 225 $ (278 ) $ (30 ) $ (507 ) 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 June 30, 2015 and December 31, 2014 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, Other Real Estate Owned In accordance with the provisions of ASC 360, Property, Plant, and Equipment, 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 June 30, 2015 and December 31, 2014. (in thousands) Quantitative Information about Level 3 Fair Value Measurements Fair Value at June 30, 2015 Valuation Technique(s) Unobservable Input Range (Weighted Average) Mortgage servicing rights $ 3,235 Discount cash flows, computer pricing model Constant prepayment rate 6.0% - 22.3% (9.8%) Probability of default 0.0% - 100.0% (3.0%) Discount rate 10.0% - 11.0% (10.1%) Impaired loans (collateral-dependent) $ 2,677 Market comparable properties Marketability discount 5.0% - 10.0% (7.0%) Other real estate/assets owned $ 1,070 Market comparable properties Comparability adjustments 5.0% - 30.0% (12.1%) (in thousands) Quantitative Information about Level 3 Fair Value Measurements Fair Value at December 31, 2014 Valuation Technique(s) Unobservable Input Range (Weighted Average) Mortgage servicing rights $ 2,968 Discount cash flows, computer pricing model Constant prepayment rate 4.6% - 25.1% (11.3%) Probability of default 0.0% - 100.0% (3.6%) Discount rate 10.0% - 11.5% (10.1%) Impaired loans (collateral-dependent) $ 4,665 Market comparable properties Marketability discount 5.0% - 10.0% (7.0%) Other real estate/assets owned $ 6,472 Market comparable properties Comparability adjustments 3.0% - 67.0% (18.0%) 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. Mortgage Servicing Rights 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 June 30, 2015 and indicates the level within the fair value hierarchy of the valuation techniques.

Certificates of deposit in other banks – Fair values are based on quoted market prices or dealer quotes for similar instruments. Securities held-to-maturity – Fair values are based on quoted market prices, if available. If a quoted price is not available, fair value is estimated using quoted prices for similar securities. The fair value estimate is provided to management from a third party using modeling assumptions specific to each type of security that are reviewed and approved by management. Quarterly sampling of fair values provided by additional third parties supplement the fair value review process. Loans held for sale – The fair value is predetermined at origination based on sale price. Loans (net of the allowance for loan and lease losses) – The fair value of fixed rate loans and variable rate mortgage loans is estimated by discounting the future cash flows using current rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities. For other variable rate loans, the carrying amount approximates fair value. Federal Home Loan Bank stock – The carrying value of Federal Home Loan Bank stock approximates fair value based on the redemption provisions of the Federal Home Loan Bank. Federal Reserve Bank stock – The carrying value of Federal Reserve Bank stock approximates fair value based on the redemption provisions of the Federal Reserve Bank. Accrued interest receivable – The carrying amount approximates fair value. Deposits – The fair value of fixed maturity time deposits is estimated by discounting the future cash flows using the rates currently offered for deposits of similar remaining maturities. For deposits including demand deposits, savings accounts, NOW accounts, and certain money market accounts, the carrying value approximates fair value. Repurchase agreements – The fair value is estimated by discounting future cash flows using current rates. Federal funds purchased – The carrying amount approximates fair value. Advances from Federal Home Loan Bank – The fair value of these fixed-maturity advances is estimated by discounting future cash flows using rates currently offered for advances of similar remaining maturities. Long-term debt – The fair value is estimated by discounting future cash flows using current rates. Accrued interest payable – The carrying amount approximates fair value. Commitments to originate loans, forward sale commitments, letters of credit, and lines of credit – The fair value of commitments to originate loans is estimated using the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the present creditworthiness of the counterparties. For fixed-rate loan commitments, fair value also considers the difference between current levels of interest rates and the committed rates. The fair value of forward sale commitments is estimated based on current market prices for loans of similar terms and credit quality. The fair values of letters of credit and lines of credit are based on fees currently charged for similar agreements or on the estimated cost to terminate or otherwise settle the obligations with the counterparties at the reporting date. The fair values of these commitments are not material.

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 Investment 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 securities are computed by specific identification for all securities except for shares in mutual funds, which are computed by average cost. 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 the CTBI's results of operations and financial condition.
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 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 310-35, 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 non-accrual 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, a charge off is taken, if necessary, in order that the remaining balance reflects the fair value estimated less costs to sell of the collateral then transferred to other real estate owned or other repossessed assets. 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. Based upon management's judgment, "best case," "worst case," and "most likely" scenarios are determined. The total of each of these weighted factors is then applied against the applicable portion of the portfolio and the ALLL is adjusted accordingly to approximate the most likely scenario. Management continually reevaluates the other subjective factors included in its ALLL analysis.

Income Taxes	Income Taxes CTBI is currently under IRS examination of its 2013 corporate income tax return. Management does not expect that the results of the examination will have a material effect on our financial condition. While management believes our tax positions are appropriate, the IRS could challenge our positions as a part of this examination.
