SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of Business and Segments Covenant Transportation Group, Inc., a Nevada holding company, together with its wholly owned subsidiaries offers truckload transportation and brokerage services to customers throughout the continental United States. We have two The Truckload segment consists of three nomic characteristics and meet the aggregation criteria. The three In addition, our Managed Freight segment has service offerings ancillary to our Truckload services, including: freight brokerage s ervice directly and through freight brokerage agents, who are paid a commission for the freight they provide. The operations consist of several operating segments, which are aggregated due to similar margins and customers. Included within Managed Freight is our account receivable factoring business which does not $3.1 Principles of Consolidation The consolidated financial statements include the accounts of Covenant Transportatio n Group, Inc., a holding company incorporated in the state of Nevada in 1994, References in this report to "it," "we," "us," "our," the "Company," and similar expressions refer to Covenant Transportation Group, Inc. and its subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation.

Revenue is recorded on a gross basis, without deducting third $3.1 $2.6 $2.4 2017, 2016, 2015, 2013 not E stimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires us to make decisions based upon estimates, assumptions, and factors we consider as relevant to the circumstances. Such decisions include the selection of applicable accounting principles and the use of judgment in their application, the results of which impact reported amounts and disclosures. Changes in future economic conditions or other business circumstances may Cash and Cash Equivalents We consider all highly liquid investments with a maturity of three equivalents. Additionally, we are also subject to concentrations of credit risk related to deposits in banks in excess of the Federal Deposit Insurance Corporation limits. Accounts Receivable and Concentration of Credit Risk We extend credit to our customers in the normal course of business. We perform ongoing credit evaluations and generally do not Accounts receivable are comprised of a diversified customer base that results in a lack of concentra tion of credit risk.

The carrying value of the factored receivables approximates the fair value, as the receivables are generally repaid directly to us by the client' s customer within 30–40 The following table provides a summary (in th ousands) of the activity in the accounts for 2017, 2016, 2015: Years ended December 31: Beginning balance January 1, Additional provisions to (reversal of) allowance Write-offs and other deductions Ending balance December 31, 201 7 $ 1,345 $ 454 $ (343 ) $ 1,456 201 6 $ 1,857 $ (241 ) $ (271 ) $ 1,345 201 5 $ 1,767 $ 1,100 $ (1,010 ) $ 1,857 Inventories and Supplies Inventories and supplies consist of parts, tires, fuel, and supplies. Tires on new revenue equipment are capitalized as a component of the related equipment cost when the tractor or trailer is placed in service and recovered through depreciation over the life of the vehicle. Replacement tires and parts on hand at year end are recorded at the lower of cost or market with cost determined using the first first Assets Held for Sale Assets held for sale include property and revenue equipment no no the lower of depreciated book value or fair market value less selling costs. We periodically review the carrying value of these assets for possible impairment. We expect to sell these assets within twelve Property and Equipment Property and equip ment is stated at cost less accumulated depreciation. Depreciation for book purposes is determined using the straight-line method over the estimated useful lives of the assets, while depreciation for tax purposes is generally recorded using an accelerated method. Depreciation of revenue equipment is our largest item of depreciation. We generally depreciate new tractors (excluding day cabs) over five 15% seven ten 25% not July 1, 2016 third 2016 2017 $2.0 $1.2 $0.06 2018 2017. We annually review the reasonableness of our estimates regarding useful lives and salvage values of our revenue equipment and other long-lived assets based upon, among other things, our experience with similar assets, conditions in the used revenue equipment market, and prevailing industry practice. Changes in the useful life or salvage value estimates, or fluctuations in market values that are not our estimates, could have a material effect on our results of operations. Gains and losses on the disposal of revenue equipment are included in depreciation expense in the consolidated statements of operations. We lease certain revenue equipment under capital leases with terms of approximately 60 84 Although a portion of our tractors are protected by non-binding in dicative trade-in values or binding trade-back agreements with the manufacturers, substantially all of our owned trailers are subject to fluctuations in market prices for used revenue equipment. Moreover, our trade-back agreements are contingent upon reaching acceptable terms for the purchase of new equipment. Declines in the price of used revenue equipment or failure to reach agreement for the purchase of new tractors with the manufacturers issuing trade-back agreements could result in impairment of, or losses on the sale of, revenue equipment. Impairment of Long-Lived Assets Pursuant to applicable accounting standards, revenue equipment and other long-lived assets are tested for impairment whenever an event occurs that indicates an impairment may Expected future cash flows are used to analyze whether an impairment has occurred. If the sum of expected undiscounted cash flows is less than the carrying value of the long-lived asset, then an impairment loss is recognized. We measure the impairment loss by comparing the fair value of the asset to its carrying value. Fair value is determined based on a discounted cash flow analysis or the appraised value of the assets, as appropriate. Goodwill and Other Intangible Assets We classify intangible assets into two no December 31, 2017 2016. may not may not We determine the useful lives of our identifiable intangible assets after considering the specific facts and circumstances related to each intangible asset. Factors we consider when determining useful lives include the contractual term of any agreement, the history of the asset, our long-term strategy for the use of the asset, any laws or other local regulations which could impact the useful life of the asset, and other economic factors, including competition and specific market conditions. Intangible assets that are deemed to have definite lives are amortized, generally on a straight-line basis, over their useful lives, ranging from 4 20 no December 31, 2017 2016 . Insurance and Other Claims The primary claims arising against us consist of auto liability (person al injury and property damage), workers' compensation, cargo, commercial liability, and employee medical expenses. Our insurance program involves self-insurance with the following risk retention levels (before giving effect to any commutation of an auto liability policy): ● auto liability - $1.0 ● workers' compensation - $1.3 ● cargo - $0.3 ● employee medical - $0.4 ● physical damage - 100% Due to our significant self-insured retention amounts, we have exposure to fluctuations in the number and severity of claims and to variations between our estimated and actual ultimate payouts. We accrue the estimated cost of the uninsured portion of pending claims and an estimate for allocated loss adjustment expenses including legal and other direct costs associated with a claim. Estimates require judgments concerning the nature and severity of the claim, historical trends, advice from third In addition to estimates within our self-insured retention layers, we also must make judgments concerning claims where we have third third 1.1 $0.7 December 31, 2017 2016, advances and other receivables on our consolidated balance sheet. Additionally, we accrue claims above our self-insured retention and record a corresponding receivable for amounts we expect to collect from insurers upon settlement of such claims. We have $2.1 $0.1 December 31, 2017 2016, may one We also make judg ments regarding the ultimate benefit versus risk of commuting certain periods within our auto liability policy.

Interest We capitalize interest on major projects during construction. Interest is capitalized based on the averag e interest rate on related debt. Capitalized interest was less than $0.1 2017, 2016, 2015. Fair Value of Financial Instrument s Our financial instruments consist primarily of cash and cash equivalents, accounts receivable, commodity contracts, accounts payable, debt, and interest rate swaps. The carrying amount of cash and cash equivalents, accounts receivable, accounts payable, and current debt approximates their fair value because of the short-term maturity of these instruments. The carrying value of the factored receivables approximates the fair value, as the receivables are generally repaid directly to us by the client's customer within 30–40 Interest rates that are currently available to us for issuance of long-term debt with similar terms and remaining maturities are used to estimate the fair value of our long-term debt, which primarily consists of revenue equipment installment notes. The fair value of our revenue equipment installment notes approximated the carrying value at December 31, 2017, 13, Income Taxes Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. We have reflected the net liability after offsetting our deferred tax assets and liabilities in the deferred income taxes line in the accompanying consolidated balance sheets in accordance with our retrospective adoption of Financial Accounting Standards Board (" FASB") Accounting Standards Update ("ASU") No. 2015 17, Income Taxes: Balance Sheet Classification of Deferred Taxes December 31, 2015, 9. In the ordinary course of business there is inherent uncertainty in quantifying our income tax positions. We assess our income tax positions and record tax benefits for all years subject to examination based upon management's evaluation of the facts, circumstances, and information available at the reporting dates. For those tax positions where it is more likely than not 50% not not no Our policy is to recognize income tax benefit arising from the exercise of stock options and restricted share vesting based on the ordering provisions of the tax law as prescribed by the Internal Revenue Code, including indirect tax effects, if any. Lease Accounting and Off-Balance Sheet Transactions We issue residual value guarantees in connection with the operating leases we enter into for certain of our revenue equipment. These leases p rovide that if we do not Capital Structure The shares of Class A and B common stock are substantially identical except that the Class B shares are entitled to two beneficially owned by anyone other than our Chief Executive Officer or certain members of his immediate family, while Class A shares are entitled to one Comprehensive Income Comprehensive income generally includes all changes in equity during a period except those resulting from investments by owners and distributions to owner s. Comprehensive income for 2017, 2016, 2015 Income Per Share Basic income per share excludes dilution and is computed by dividing earnings available to common stockholders by the weighted-average number of common shares outstanding for the period.

Performance-based awards vest contingent upon meeting certain performance criteria established by the Compensation Committee of the Board of Directors. All awards require future service. For performance-based awards, determining the appropriate amount to expense in each period is based on likelihood and timing of achieving the stated targets for performance-based awards and requires judgment, including forecasting future financial results. The estimates are revised periodically based on the probability and timing of achieving the required performance and adjustments are made as appropriate. Awards that are only subject to time vesting provisions are amortized using the straight-line method. Derivative Instruments and Hedging Activities We periodically utilize derivative instruments to manage exposure to changes in fue l prices and interest rates. We record derivative financial instruments in the balance sheet as either an asset or liability at fair value. Previously, at inception of a derivative contract, we documented relationships between derivative instruments and hedged items, as well as our risk-management objective and strategy for undertaking various derivative transactions, and assessed hedge effectiveness.

Fair Value Disclosures [Text Block]	3. FAIR VALUE OF FINANCIAL INSTRUMENTS Fair value is defined as an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. Accordingly, fair value is a market-based measurement that is determined based on assumptions that market participants would use in pricing an asset or liability. The fair value of the hedge derivative liability was determined based on quotes from the counterparty which were verified by comparing them to the exchange on which the related futures are traded, adjusted for counterparty credit risk. The fair value of our interest rate swap agreement is determined using the market-standard methodology of netting the discounted future fixed-cash payments and the discounted expected variable-cash receipts. The variable-cash receipts are based on an expectation of future interest rates (forward curves) derived from observable market interest rate curves. These analyses reflect the contractual terms of the swap, including the period to maturity, and use observable market-based inputs, including interest rate curves and implied volatilities. The fair value calculation also includes an amount for risk of non-performance of our counterparties using "significant unobservable inputs" such as estimates of current credit spreads to evaluate the likelihood of default, which we have determined to be insignificant to the overall fair value of our interest rate swap agreement.

Drivers who meet the requirements to receive per diem receive non-taxable per diem pay in lieu of a portion of their taxable wages. This per diem program increases our drivers' net pay per mile, after taxes, while decreasing gross pay, before taxes. As a result, salaries, wages, and employee benefits are slightly lower and our effective income tax rate is higher than the statutory rate. Generally, as pre-tax income increases, the impact of the driver per diem program on our effective tax rate decreases, because aggregate per diem pay becomes smaller in relation to pre-tax income, while in periods where earnings are at or near breakeven, the impact of the per diem program on our effective tax rate is significant.

Financial exposures are evaluate d as an integral part of our risk management program, which seeks, from time-to-time, to reduce the potentially adverse effects that the volatility of fuel markets and interest rate risk may In an effort to seek to reduce the variability of the ultimate cash flows associated with fluctuations in diesel fuel prices, we periodically enter into various derivative instruments, including forward futures swap contracts. Specifically, we enter into hedging contracts with respect to ultra-low sulfur diesel ( "ULSD "). Under these contracts, we pay a fixed rate per gallon of ULSD and receive the monthly average price of Gulf Coast ULSD.

The change in fair value of the hedge offsets the change in fair value of the hedged item . At December 31, 2017 , we had fuel hedge contracts on approximately 7.6 2018, 16.1% 2018 The fair value of the contracts that were in effect at December 31, 2017 2016, $0.8 $3.6 . Changes in the fair values of these instruments can vary dramatically based on changes in the underlying commodity prices. For example, during 2017, $1.97 $1.33 2016, $1.66 $0.83 Additionally, $4.1 $16.7 $15.3 December 31, 2017, 2016, 2015, 2017, 2016, 2015, , in 2015 $1.4 2014 . As a result, the changes in fair value for those contracts were recorded as expense rather than as a component of other comprehensive loss. At December 31, 2017, Based on the amounts in accumulated other comprehens ive income as of December 31, 2017 $0.6 We perform both a prospective and retrospective assessment of the effectiveness of our hedge contracts at inception and qu arterly, including assessing the possibility of counterparty default. If we determine that a derivative is no December 31, 2017 2016, Outstanding financial derivative instruments expose us to credit loss in the event of nonperformance by the counterparties to the agreements. We do not Our credit exposure related to these financial instruments is represented by the fair value of contracts reported as assets. To manage credit risk, we review each counterparty's audited financial statements, credit ratings, and/or obtain references as we deem necessary.

Use of Estimates, Policy [Policy Text Block]	E stimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires us to make decisions based upon estimates, assumptions, and factors we consider as relevant to the circumstances. Such decisions include the selection of applicable accounting principles and the use of judgment in their application, the results of which impact reported amounts and disclosures. Changes in future economic conditions or other business circumstances may
Cash and Cash Equivalents, Policy [Policy Text Block]	Cash and Cash Equivalents We consider all highly liquid investments with a maturity of three equivalents. Additionally, we are also subject to concentrations of credit risk related to deposits in banks in excess of the Federal Deposit Insurance Corporation limits.
Loans and Leases Receivable, Allowance for Loan Losses Policy [Policy Text Block]	Accounts Receivable and Concentration of Credit Risk We extend credit to our customers in the normal course of business.

Inventory, Policy [Policy Text Block]	Inventories and Supplies Inventories and supplies consist of parts, tires, fuel, and supplies. Tires on new revenue equipment are capitalized as a component of the related equipment cost when the tractor or trailer is placed in service and recovered through depreciation over the life of the vehicle. Replacement tires and parts on hand at year end are recorded at the lower of cost or market with cost determined using the first first
Assets Held for Sale Policy [Policy Text Block]	Assets Held for Sale Assets held for sale include property and revenue equipment no no the lower of depreciated book value or fair market value less selling costs. We periodically review the carrying value of these assets for possible impairment. We expect to sell these assets within twelve
Property, Plant and Equipment, Policy [Policy Text Block]	Property and Equipment Property and equip ment is stated at cost less accumulated depreciation. Depreciation for book purposes is determined using the straight-line method over the estimated useful lives of the assets, while depreciation for tax purposes is generally recorded using an accelerated method. Depreciation of revenue equipment is our largest item of depreciation. We generally depreciate new tractors (excluding day cabs) over five 15% seven ten 25% not July 1, 2016 third 2016 2017 $2.0 $1.2 $0.06 2018 2017. We annually review the reasonableness of our estimates regarding useful lives and salvage values of our revenue equipment and other long-lived assets based upon, among other things, our experience with similar assets, conditions in the used revenue equipment market, and prevailing industry practice. Changes in the useful life or salvage value estimates, or fluctuations in market values that are not our estimates, could have a material effect on our results of operations. Gains and losses on the disposal of revenue equipment are included in depreciation expense in the consolidated statements of operations. We lease certain revenue equipment under capital leases with terms of approximately 60 84 Although a portion of our tractors are protected by non-binding in dicative trade-in values or binding trade-back agreements with the manufacturers, substantially all of our owned trailers are subject to fluctuations in market prices for used revenue equipment. Moreover, our trade-back agreements are contingent upon reaching acceptable terms for the purchase of new equipment. Declines in the price of used revenue equipment or failure to reach agreement for the purchase of new tractors with the manufacturers issuing trade-back agreements could result in impairment of, or losses on the sale of, revenue equipment.
Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block]	Impairment of Long-Lived Assets Pursuant to applicable accounting standards, revenue equipment and other long-lived assets are tested for impairment whenever an event occurs that indicates an impairment may Expected future cash flows are used to analyze whether an impairment has occurred. If the sum of expected undiscounted cash flows is less than the carrying value of the long-lived asset, then an impairment loss is recognized. We measure the impairment loss by comparing the fair value of the asset to its carrying value. Fair value is determined based on a discounted cash flow analysis or the appraised value of the assets, as appropriate.
Goodwill and Intangible Assets, Policy [Policy Text Block]	Goodwill and Other Intangible Assets We classify intangible assets into two no December 31, 2017 2016. may not may not We determine the useful lives of our identifiable intangible assets after considering the specific facts and circumstances related to each intangible asset. Factors we consider when determining useful lives include the contractual term of any agreement, the history of the asset, our long-term strategy for the use of the asset, any laws or other local regulations which could impact the useful life of the asset, and other economic factors, including competition and specific market conditions. Intangible assets that are deemed to have definite lives are amortized, generally on a straight-line basis, over their useful lives, ranging from 4 20 no December 31, 2017 2016 .
Insurance And Other Claims [Policy Text Block]	Insurance and Other Claims The primary claims arising against us consist of auto liability (person al injury and property damage), workers' compensation, cargo, commercial liability, and employee medical expenses. Our insurance program involves self-insurance with the following risk retention levels (before giving effect to any commutation of an auto liability policy): ● auto liability - $1.0 ● workers' compensation - $1.3 ● cargo - $0.3 ● employee medical - $0.4 ● physical damage - 100% Due to our significant self-insured retention amounts, we have exposure to fluctuations in the number and severity of claims and to variations between our estimated and actual ultimate payouts. We accrue the estimated cost of the uninsured portion of pending claims and an estimate for allocated loss adjustment expenses including legal and other direct costs associated with a claim. Estimates require judgments concerning the nature and severity of the claim, historical trends, advice from third In addition to estimates within our self-insured retention layers, we also must make judgments concerning claims where we have third third 1.1 $0.7 December 31, 2017 2016, advances and other receivables on our consolidated balance sheet.

Fair Value of Financial Instruments, Policy [Policy Text Block]	Fair Value of Financial Instrument s Our financial instruments consist primarily of cash and cash equivalents, accounts receivable, commodity contracts, accounts payable, debt, and interest rate swaps. The carrying amount of cash and cash equivalents, accounts receivable, accounts payable, and current debt approximates their fair value because of the short-term maturity of these instruments. The carrying value of the factored receivables approximates the fair value, as the receivables are generally repaid directly to us by the client's customer within 30–40 Interest rates that are currently available to us for issuance of long-term debt with similar terms and remaining maturities are used to estimate the fair value of our long-term debt, which primarily consists of revenue equipment installment notes. The fair value of our revenue equipment installment notes approximated the carrying value at December 31, 2017, 13,
Income Tax, Policy [Policy Text Block]	Income Taxes Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. We have reflected the net liability after offsetting our deferred tax assets and liabilities in the deferred income taxes line in the accompanying consolidated balance sheets in accordance with our retrospective adoption of Financial Accounting Standards Board (" FASB") Accounting Standards Update ("ASU") No. 2015 17, Income Taxes: Balance Sheet Classification of Deferred Taxes December 31, 2015, 9. In the ordinary course of business there is inherent uncertainty in quantifying our income tax positions. We assess our income tax positions and record tax benefits for all years subject to examination based upon management's evaluation of the facts, circumstances, and information available at the reporting dates. For those tax positions where it is more likely than not 50% not not no Our policy is to recognize income tax benefit arising from the exercise of stock options and restricted share vesting based on the ordering provisions of the tax law as prescribed by the Internal Revenue Code, including indirect tax effects, if any.

Comprehensive Income, Policy [Policy Text Block]	Comprehensive Income Comprehensive income generally includes all changes in equity during a period except those resulting from investments by owners and distributions to owner s. Comprehensive income for 2017, 2016, 2015
Earnings Per Share, Policy [Policy Text Block]	Income Per Share Basic income per share excludes dilution and is computed by dividing earnings available to common stockholders by the weighted-average number of common shares outstanding for the period. Diluted income per share reflects the dilution that could occur if s ecurities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in our earnings. The calculation of diluted earnings per share includes approximately 0.1 December 31, 2017, 2016 , and 2015, . Income per share is the same for both Class A and Class B shares.

Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	Stock-Based Employee Compensation We issue several types of stock-based compensation, including awards that vest based on service and performance conditions or a combination of the conditions. Performance-based awards vest contingent upon meeting certain performance criteria established by the Compensation Committee of the Board of Directors. All awards require future service. For performance-based awards, determining the appropriate amount to expense in each period is based on likelihood and timing of achieving the stated targets for performance-based awards and requires judgment, including forecasting future financial results. The estimates are revised periodically based on the probability and timing of achieving the required performance and adjustments are made as appropriate. Awards that are only subject to time vesting provisions are amortized using the straight-line method.
Derivatives, Policy [Policy Text Block]	Derivative Instruments and Hedging Activities We periodically utilize derivative instruments to manage exposure to changes in fue l prices and interest rates. We record derivative financial instruments in the balance sheet as either an asset or liability at fair value. Previously, at inception of a derivative contract, we documented relationships between derivative instruments and hedged items, as well as our risk-management objective and strategy for undertaking various derivative transactions, and assessed hedge effectiveness.
