COVENANT TRANSPORTATION GROUP, INC. AND SUBSIDIARIES
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)
 
 
Note 1.Significant Accounting Policies
 
Basis of Presentation
 
The condensed consolidated financial statements include the accounts of Covenant Transportation Group, Inc., a Nevada holding company, and its wholly owned subsidiaries. References in this report to "we," "us," "our," the "Company," and similar expressions refer to Covenant Transportation Group, Inc. and its wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation.
 
The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X promulgated under the Securities Act of 1933. In preparing financial statements, it is necessary for management to make assumptions and estimates affecting the amounts reported in the condensed consolidated financial statements and related notes. These estimates and assumptions are developed based upon all information available. Actual results could differ from estimated amounts. In the opinion of management, the accompanying financial statements include all adjustments that are necessary for a fair presentation of the results for the interim periods presented, such adjustments being of a normal recurring nature.
 
Certain information and footnote disclosures have been condensed or omitted pursuant to such rules and regulations. The December 31, 2018, condensed consolidated balance sheet was derived from our audited balance sheet as of that date. Our operating results are subject to seasonal trends when measured on a quarterly basis; therefore operating results for the three months ended March 31,June 30, 2019 are not necessarily indicative of the results that may be expected for the year ending December 31, 2018. These condensed consolidated financial statements and notes thereto should be read in conjunction with the consolidated financial statements and notes thereto included in our Form 10-K for the year ended December 31, 2018. Results of operations in interim periods are not necessarily indicative of results to be expected for a full year.
 
Recent Accounting Pronouncements
 
Accounting Standards adopted
 
In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-02, which establishes Topic 842 to replace Topic 840 regarding accounting for leases. Topic 842 requires lessees to recognize a right-of-use asset and a lease liability for most leases on the balance sheet. Leases that were previously described as capital leases are now called finance leases, and operating leases with a term of at least twelve months are now required to be recorded on the balance sheet. We adopted this standard on January 1, 2019 using the modified retrospective approach.
 
In July 2018, FASB issued ASU 2018-11, which provides an optional transition method allowing application of Topic 842 as of the adoption date and recognition of a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption, with no restatement of comparative prior periods. We have adopted the standard using this optional transition method.
 
Within Topic 842, FASB has provided a number of practical expedients for applying the new lease standard in relation to leases that commenced prior to the standard's effective date. We have elected the package of practical expedients which allowed us, among other things, to carry forward the operating and capital lease classifications from Topic 840 to the new operating and finance lease classifications under Topic 842.
 
The adoption of this ASU resulted in the initial recognition of operating lease assets of $40.1 million and liabilities totaling approximately $40.2$41.0 million, comprised of $14.6$15.3 million of current liabilitiesoperating lease obligations and $25.6$25.7 million of long-term operating lease obligations.
 
Property and Equipment
 
Property and equipment 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 have historically depreciated new tractors (excluding day cabs) over five years to salvage values of approximately 15% of their cost.  We generally depreciate new trailers over seven years for refrigerated trailers and ten years for dry van trailers to salvage values of approximately 25% of their cost. 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 reflected in 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.
Page 8

Leases
 
At the commencement date of a new lease agreement with contractual terms longer than twelve months, we recognize a right-of-use asset and a lease liability and categorize the lease as either finance or operating. Certain lease agreements have lease and nonlease components, and we have elected to account for these components separately.
 
Right-of-use assets and lease liabilities are initially recorded based on the present value of lease payments over the term of the lease. When the rate implicit in the lease is readily determinable, this rate is used for calculating the present value of remaining lease payments; otherwise, our incremental borrowing rate is used. Right-of-use assets also include prepaid lease expenses and initial direct costs of executing the leases, which are reduced by landlord incentives. Options to extend or terminate a lease agreement are included in or excluded from the lease term, respectively, when those options are reasonably certain to be exercised. Right-of-use assets are tested for impairment in the same manner as long-lived assets.
 
Right-of-use assets are included in net property and equipment. For finance leases, right-of-use assets are amortized on a straight-line basis over the shorter of the expected useful life or the lease term, and the carrying amount of the lease liability is adjusted to reflect interest expense, which is recorded in interest expense, net. Operating lease right-of-use assets are amortized over the lease term on a straight-line basis, and the lease liability is measured at the present value of the remaining lease payments. Variable lease payments not included in the lease liability for mileage charges on leased revenue equipment are expensed as incurred. Operating lease costs are recognized on a straight-line basis over the term of the lease within operating expenses.
 
 
Note 2.Income Per Share
 
Basic income (loss) 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 (loss) per share reflects the dilution that could occur if securities 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. There were no anti-dilutive shares for the three or six months ended March 31,June 30, 2019. There were no outstanding stock options at March 31,June 30, 2019. Income per share is the same for both Class A and Class B shares.
 
The following table sets forth for the periods indicated the calculation of net income per share included in the condensed consolidated statements of operations:

Note 3.Segment Information
 
We have two reportable segments, Truckload, which is comprised of our truckload services, and Managed Freight, which provides freight brokerage and logistics services.
 
The Truckload segment consists of four service offerings that are aggregated because they have similar economic characteristics and meet the aggregation criteria.  The four service offerings that comprise our Truckload segment are as follows: (i) Expedited, provided primarily by Covenant Transport, Inc., our historical flagship operation; (ii) Dedicated, provided by all of our operating fleets; (iii) Refrigerated, provided primarily through our Southern Refrigerated Transport, Inc. ("SRT") subsidiary; and (iv) over-the-road ("OTR"), provided primarily by our Landair Transport, Inc. subsidiary.
 
In addition, our Managed Freight segment has service offerings ancillary to our Truckload services, including: freight brokerage, transportation management services ("TMS"), and shuttle and switching services. The operations consist of several operating segments, whichThese service offerings are aggregated due to similar margins and customers. IncludedAlso included within Managed Freight are our warehousing and accounts receivable factoring and warehousing businesses, neither of which meets the quantitative or qualitative reporting thresholds individually or in the aggregate.
 
The accounting policies of the segments are the same as those described in the summary of significant accounting policies in our 2018 Annual Report on Form 10-K. Substantially all intersegment sales prices are market based. We evaluate performance based on operating income of the respective business units.
 
The following table summarizes our revenue by our two reportable segments, Truckload and Managed Freight, disaggregated to the operating fleet level as used by our chief operating decision maker in making decisions regarding allocation of resources and assets, organized first by reportable segment (i.e. Truckload and Managed Freight) and then by operating fleet for the three and six months ended March 31, 2019:June 30, 2019 and 2018:

Note 4.Income Taxes
 
Income tax expense in both 2019 and 2018 varies from the amount computed by applying the federal corporate income tax rates of 21% to income before income taxes, primarily due to state income taxes, net of federal income tax effect, adjusted for permanent differences, the most significant of which is the effect of the per diem pay structure for drivers.  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 related expenses 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.  Due to the partially nondeductible effect of per diem pay, our tax rate will fluctuate in future periods based on fluctuations in earnings.
Page 10

Our liability recorded for uncertain tax positions as of March 31,June 30, 2019 has increased by less than $0.1 million for accrued interest since December 31, 2018.
 
The net deferred tax liability of $78.4$80.9 million primarily relates to differences in cumulative book versus tax depreciation of property and equipment, partially off-set by net operating loss carryovers and insurance claims that have been reserved but not paid. The carrying value of our deferred tax assets assumes that we will be able to generate, based on certain estimates and assumptions, sufficient future taxable income in certain tax jurisdictions to utilize these deferred tax benefits.  If these estimates and related assumptions change in the future, we may be required to establish a valuation allowance against the carrying value of the deferred tax assets, which would result in additional income tax expense.  On a periodic basis, we assess the need for adjustment of the valuation allowance.  Based on forecasted taxable income resulting from the reversal of deferred tax liabilities, primarily generated by accelerated depreciation for tax purposes in prior periods, and tax planning strategies available to us, a valuation allowance has been established at March 31,June 30, 2019, for less than $0.1 million related to certain state net operating loss carry-forwards.  If these estimates and related assumptions change in the future, we may be required to modify our valuation allowance against the carrying value of the deferred tax assets.

We and substantially all of our subsidiaries are parties to a Third Amended and Restatedthe Credit Facility (the “Credit Facility”) with Bank of America, N.A., as agent (the "Agent") and JPMorgan Chase Bank, N.A. (together with the Agent, the "Lenders"). The Credit Facility is a $95.0 million revolving credit facility, with an uncommitted accordion feature that, so long as no event of default exists, allows us to request an increase in the revolving credit facility of up to $50.0 million subject to Lender acceptance of the additional funding commitment.  The Credit Facility includes, within our $95.0 million revolving credit facility, a letter of credit sub facility in an aggregate amount of $95.0 million and a swing line sub facility in an aggregate amount equal to the greater of $10.0 million or 10% of the Lenders' aggregate commitments under the Credit Facility from time-to-time. The Credit Facility matures in September 2021.
 
Borrowings under the Credit Facility are classified as either "base rate loans" or "LIBOR loans." Base rate loans accrue interest at a base rate equal to the greater of the Agent’s prime rate, the federal funds rate plus 0.5%, or LIBOR plus 1.0%, plus an applicable margin ranging from 0.5% to 1.0%; while LIBOR loans accrue interest at LIBOR, plus an applicable margin ranging from 1.5% to 2.0%. The applicable rates are adjusted quarterly based on average pricing availability. The unused line fee is the product of 0.25% times the average daily amount by which the Lenders' aggregate revolving commitments under the Credit Facility exceed the outstanding principal amount of revolver loans and the aggregate undrawn amount of all outstanding letters of credit issued under the Credit Facility.  The obligations under the Credit Facility are guaranteed by us and secured by a pledge of substantially all of our assets, with the notable exclusion of any real estate or revenue equipment pledged under other financing agreements, including revenue equipment installment notes and financecapital leases.
Page 11

 
Borrowings under the Credit Facility are subject to a borrowing base limited to the lesser of (A) $95.0 million, minus the sum of the stated amount of all outstanding letters of credit; or (B) the sum of (i) 85% of eligible accounts receivable, plus (ii) the lesser of (a) 85% of the appraised net orderly liquidation value of eligible revenue equipment, (b) 95% of the net book value of eligible revenue equipment, or (c) 35% of the Lenders' aggregate revolving commitments under the Credit Facility, plus (iii) the lesser of (a) $25.0 million or (b) 75% of the appraised fair market value of eligible real estate, as reduced by a periodic amortization amount.  We had $29.6$17.3 million of borrowings outstanding under the Credit Facility as of March 31,June 30, 2019, undrawn letters of credit outstanding of approximately $33.4$34.8 million, and available borrowing capacity of $32.0$42.9 million. The interest rate on outstanding borrowings as of March 31,June 30, 2019, was 6.0% on $29.6$17.3 million of base rate loans and there were no outstanding LIBOR loans. Based on availability as of March 31,June 30, 2019 and 2018, there was no fixed charge coverage requirement.
 
The Credit Facility includes usual and customary events of default for a facility of this nature and provides that, upon the occurrence and continuation of an event of default, payment of all amounts payable under the Credit Facility may be accelerated, and the Lenders' commitments may be terminated.  If an event of default occurs under the Credit Facility and the Lenders cause, or have the ability to cause, all of the outstanding debt obligations under the Credit Facility to become due and payable, this could result in a default under other debt instruments that contain acceleration or cross-default provisions. The Credit Facility contains certain restrictions and covenants relating to, among other things, debt, dividends, liens, acquisitions and dispositions outside of the ordinary course of business, and affiliate transactions. Failure to comply with the covenants and restrictions set forth in the Credit Facility could result in an event of default.
 
Pricing for the revenue equipment installment notes is quoted by the respective financial affiliates of our primary revenue equipment suppliers and other lenders at the funding of each group of equipment acquired and include fixed annual rates for new equipment under retail installment contracts. The notes included in the funding are due in monthly installments with final maturities at various dates ranging from AprilJuly 2019 to JulySeptember 2023. The notes contain certain requirements regarding payment, insuring of collateral, and other matters, but do not have any financial or other material covenants or events of default except certain notes totaling $146.3$176.7 million are cross-defaulted with the Credit Facility. Additional borrowings from the financial affiliates of our primary revenue equipment suppliers and other lenders are expected to be available to fund new tractors expected to be delivered in 2020, while any other property and equipment purchases, including trailers, are expected to be funded with a combination of available cash, notes, operating leases, financecapital leases, and/or from the Credit Facility.
 
In August 2015, we financed a portion of the purchase of our corporate headquarters, a maintenance facility, and certain surrounding property in Chattanooga, Tennessee by entering into a $28.0 million variable rate note with a third party lender. Concurrently with entering into the note, we entered into an interest rate swap to effectively fix the related interest rate to 4.2%.
  
Note 6.Stock-Based Compensation
 
Our 2006 Omnibus Incentive Plan, as amended (the "Incentive Plan") governs the issuance of equity awards and other incentive compensation to management and members of the board of directors. In February 2013,On May 8, 2019, the Compensation Committee re-approved, subject to stockholder re-approval, the material termsstockholders, upon recommendation of the performance-based goalsboard of directors, approved the First Amendment (the “First Amendment”) to the Third Amended and Restated Incentive Plan. The First Amendment (i) increases the number of shares of Class A common stock available for issuance under the Incentive Plan so thatby an additional 750,000 shares, (ii) implements additional changes designed to comply with certain incentive awards granted thereunder would continueshareholder advisory group guidelines and best practices, (iii) makes technical updates related to qualify as exempt "performance-based compensation" underSection 162(m) of the Internal Revenue Code Section 162(m). Our stockholders re-approved the material termsin light of the performance-based goals under2017 Tax Cuts and Jobs Act, (iv) re-sets the term of the Incentive Plan at our 2013 Annual Meeting heldto expire with respect to the ability to grant new awards on May 29, 2013.March 31, 2029, and (v) makes such other miscellaneous, administrative and conforming changes as were necessary.
 
The Incentive Plan permits annual awards of shares of our Class A common stock to executives, other key employees, consultants, non-employee directors, and eligible participants under various types of options, restricted stock awards, or other equity instruments. At March 31,As of  June 30, 2019, 50,960there were 780,747 remaining of the abovementioned 1,550,0002,300,000 shares were available for award under the Incentive Plan. No participant in the Incentive Plan may receive awards of any type of equity instruments in any calendar year that relates to more than 200,000 shares of our Class A common stock. No awards may be made under the Incentive Plan after March 31, 2023. To the extent available, we have issued treasury stock to satisfy all share-based incentive plans.
 
Included in salaries, wages, and related expenses within the condensed consolidated statements of operations is the reversal of $1.8 million and the recognition of approximately $0.9 million stock-based compensation expense for the three months ended March 31,June 30, 2019 and 2018, is stock-based compensation expenserespectively and the reversal of approximately $1.3$0.5 million and $0.8recognition of $1.8 million for the six months ended June 30, 2019 and 2018, respectively. All stock compensation expense recorded in 2019 and 2018 relates to restricted shares, as no unvested options were outstanding during these periods. An additional $0.4 million of stock-based compensation was recorded in general supplies and expenses in the condensed consolidated statements of operations for each of the three- and six-month periods ended June 30, 2019 and 2018, respectively, as this amount relates to the issuance of restricted stock to non-employee directors.
 
Page 12

The Incentive Plan allows participants to pay the federal and state minimum statutory tax withholding requirements related to awards that vest or allows participants to deliver to us shares of Class A common stock having a fair market value equal to the minimum amount of such required withholding taxes. To satisfy withholding requirements for shares that vested through March 31,June 30, 2019, certain participants elected to forfeit receipt of an aggregate of 29,390 shares of Class A common stock at a weighted average per share price of $22.71 based on the closing price of our Class A common stock on the dates the shares vested in 2019, in lieu of the federal and state minimum statutory tax withholding requirements. We remitted $0.7 million to the proper taxing authorities in satisfaction of the employees' minimum statutory withholding requirements.
 
Note 7.Commitments and Contingencies
 
From time-to-time, we are a party to ordinary, routine litigation arising in the ordinary course of business, most of which involves claims for personal injury and property damage incurred in connection with the transportation of freight.
Our subsidiary Covenant Transport, Inc. (“Covenant Transport”) is a defendant in a lawsuit filed on November 9, 2018, in the Superior Court of Los Angeles County, California.  The lawsuit was filed on behalf of Richard Tabizon (a California resident and former driver) who is seeking to have the lawsuit certified as a class action.  The complaint asserts that the time period covered by the lawsuit is from October 31, 2014 to the present and alleges claims for failure to properly pay for rest breaks, failure to provide accurate itemized wage statements and/or reimbursement of business related expenses, unlawful deduction of wages, failure to pay proper minimum wage and overtime wages, failure to provide all wages due at termination, and other related wage and hour claims under the California Labor Code.  Since the original filing date, the case has been removed from the Los Angeles Superior Court to the U.S. District Court in the Central District of California and subsequently the case was transferred to the U.S. District Court in the Eastern District of Tennessee where the case is now pending. We do not currently have enough information to make a reasonable estimate as to the likelihood, or amount of a loss, or a range of reasonably possible losses as a result of this claim, as such there have been no related accruals recorded as of June 30, 2019.   
Also, in February, 2019, Covenant Transport was named in a separate (but related) lawsuit filed in the Superior Court of Los Angeles County, California requesting civil penalties under the California Private Attorneys’ General Act for the same underlying wage and hour claims at issue in the putative class action case noted above. On August 1, 2019, the Los Angeles Superior Court entered an order staying the action pending completion of the earlier-filed action that is pending in the United States District Court for the Eastern District of Tennessee. We do not currently have enough information to make a reasonable estimate as to the likelihood, or amount of a loss, or a range of reasonably possible losses as a result of this claim, as such there have been no related accruals recorded as of June 30, 2019. 
 
We maintain insurance to cover liabilities arising from the transportation of freight for amounts in excess of certain self-insured retentions. In management's opinion, our potential exposure under pending legal proceedings is adequately provided for in the accompanying condensed consolidated financial statements.
 
Based on our present knowledge of the facts and, in certain cases, advice of outside counsel, management believes the resolution of open claims and pending litigation, taking into account existing reserves, is not likely to have a materially adverse effect on our consolidated financial statements.
 
We had $33.4$34.8 million and $36.3 million of outstanding and undrawn letters of credit as of March 31,June 30, 2019 and December 31, 2018, respectively. The letters of credit are maintained primarily to support our insurance programs.
  
Note 8.Leases
 
We finance a portion of our revenue equipment, office and terminal properties, computer and office equipment, and other equipment using leases. A number of these leases include one or more options to renew or extend the agreements beyond the expiration date or to terminate the agreement prior to the lease expiration date, and such options are included in or excluded from the lease term, respectively, when those options are reasonably certain to be exercised. Our lease obligations do not typically include residual value guarantees or material restrictive covenants. A summary of our lease obligations at March 31,June 30, 2019 isare as follows:

Note 9.Equity Method Investment
 
We own a minority investment in Transport Enterprise Leasing, LLC ("TEL"). TEL is a tractor and trailer equipment leasing company and used equipment reseller. We have not guaranteed any of TEL's debt and have no obligation to provide funding, services, or assets. In May 2016, the operating agreement with TEL was amended to, among other things, remove the previously agreed to fixed date purchase options. TEL’s majority owners are generally restricted from transferring their interests in TEL, other than to certain permitted transferees, without our consent. We sold no and $0.1 million tractors or trailers to TEL during the quartersix-months ended March 31,June 30, 2019 and 2018, respectively, and we sold $0.1 million to TEL during the same 2018 quarter. We received $2.4$4.6 million and $2.1$3.9 million, respectively, for providing various maintenance services, certain back-office functions, and for miscellaneous equipment. We recognized a net reversal of previously deferred gains totaling less than $0.1 million and $0.2 million for the three monthssix-months ended March 31,June 30, 2019 and 2018, respectively, representing 49% of the gains on units sold to TEL less any gains previously deferred and recognized when the equipment was subsequently sold to a third party.  Deferred gains, totaling $0.2$0.2 million at March 31,June 30, 2019, are being carried as a reduction in our investment in TEL.  At March 31,June 30, 2019 and December 31, 2018, we had accounts receivable from TEL of $5.6$5.6 million and $7.2$5.1 million, respectively, related to cash disbursements made pursuant to our performance of certain back-office and maintenance functions on TEL’s behalf.
We have accounted for our investment in TEL using the equity method of accounting, and thus our financial results include our proportionate share of TEL's 2019 net income through March 31,June 30, 2019, or $3.0$5.4 million. Our investment in TEL, totaling $29.1$31.5 million and $26.1 million, at March 31,June 30, 2019 and December 31, 2018, respectively, is included in other assets in the accompanying condensed consolidated balance sheets.

Note 11.10.Goodwill and Other Assets
 
On July 3, 2018, we acquired 100% of the outstanding stock of Landair Holdings, Inc., a Tennessee corporation (“Landair”). Landair is a dedicated and for-hire truckload carrier, as well as a supplier of transportation management, warehousing and logistics inventory management services. Landair’s results have been included in the consolidated financial statements since the date of acquisition. Landair’s trucking operations’ results are reported within our Truckload segment, while Landair’s logistics operations’ results are reported within our Managed Freight segment.
 
The allocation of the preliminary purchase price ishas been subject to change based on finalization of the valuation of long-lived and intangible assets and self-insurance reserves, as well as our ongoing evaluation of Landair's accounting principles for consistency with ours. The assignment of goodwill and intangible assets to our reportable segments has not been completed as of March 31,June 30, 2019.  A summary of the changes in carrying amount of total goodwill is as follows:

Executive Overview
 
Our earnings per sharefinancial results for the firstsecond quarter were comparable toillustrate the 2018 quarter despite a significantly weaker freight environment.  The Landair acquisition in July 2018, the growth ofreason for our other dedicated and brokerage business, and improved profitability from our factoring business and our minority investment in TEL more than offset the impact of lower revenue per tractor and higher operating costs. Although we are not satisfied with our first quarter financial results, we believe they reflect less impact from the reduced freight demand than in historical periods, as our growing dedicated and more contractually guaranteed service offerings generated approximately double-digit operating margins while our more seasonal and cyclical service offerings generated low single digit to negative operating margins. We attribute the consolidated improvement to our ongoing strategy of becoming increasinglymore embedded in our customers’ supply chainschains.  Our dedicated contract operations in our Star and Landair subsidiaries, along with our managed freight and factoring businesses, and our investment in TEL, performed quite well. On the other hand, our less contracted expedited and solo refrigerated operations suffered from over-supply in relation to reduce the cyclicality ofdemand and a late-developing produce season.  We intend to continue to pursue a more predictable and consistently profitable business model as we allocate assets across our business.

operations.
 
The main positives in the firstsecond quarter were 1) improvement in the operating income and operating margin at our Managed Freight segment, including successful integration of Landair’s warehousing and transportation management service offerings, 2) the organic growth of our freight brokerage service offering as compared to the first quarter of 2018, and 3) improved year-over-year earnings contributed from our investment in TEL.Transport Enterprise Leasing, and 3) consistent demand and profitability from our growing dedicated businesses at Landair and Star. The main negatives in the quarter were 1) the operating margin declines of our expedited and solo refrigerated service offerings, 2) an approximate 6.1%10.6% decrease in average freight revenue per tractortruck for our Truckload segment, excluding Landair’s truckload operations versus the firstsecond quarter of 2018, and 3) increased Truckload operating costs on a per mile basis, most notably the unfavorable employeeprimarily from increased professional driver wages, group health insurance, net fuel costs and casualty insurance claims costs, partially offset by improved net depreciation expense,operations and 4) the $23.2 million quarterly increase in our total net indebtedness primarily related to the growth of receivables purchased by our factoring division during the first quarter of 2019.maintenance expense.

Additional items of note for the firstsecond quarter of 2019 include the following:
 
 Total revenue of $219.2$219.3 million, an increase of 26.3%11.7% compared with the firstsecond quarter of 2018, and freight revenue of $195.8$194.9 million (which excludes revenue from fuel surcharges), an increase of 30.1%14.2% compared with the firstsecond quarter of 2018;
   
 Operating income of $5.4$8.8 million, compared with operating income of $6.4$14.1 million in the firstsecond quarter of 2018;
   
 Net income of $4.4$6.1 million, or $0.24$0.33 per basic and diluted share, compared with net income of $4.4$10.0 million , or $0.24$0.54 per basic and diluted share, in the firstsecond quarter of 2018;
   
 With available borrowing capacity of $32.0$42.9 million under our Credit Facility as of March 31,at June 30, 2019, we do not expect to be required to test our fixed charge covenant in the foreseeable future;
   
 Our Managed Freight segment’s total revenue increased to $46.6$43.9 million in the 2019 quarter from $19.0$25.6 million in the 2018 quarter and operating income increased to $4.2$3.7 million in the 2019 quarter from $1.1$2.3 million in the 2018 quarter;  
   
 Our equity investment in TEL provided $3.0$2.4 million of pre-tax earnings compared to $1.5$1.8 million in the firstsecond quarter of 2018;
   
 Since December 31, 2018, total indebtedness, net indebtednessof cash and including operating lease liabilities, increased by $23.2$39.9 million to $279.0$294.5 million; and 
   
 Stockholders' equity and tangible book value at March 31,June 30, 2019, were $347.7$351.7 million or $14.94and $278.1 million (or $15.08 per basic share.share), respectively.
 
We intendFor the second half of 2019, our focus will be on identifying opportunities to continue executing our strategic plan of becoming increasingly embedded in our customers’ supply chains by growing our Managed Freight segment andimprove the portionsperformance of our Truckload segmentone-way truckload service offerings and adding profitable contract logistics service customers with more predictable long-term contracts. Based on the current freight marketcontracts in our dedicated truckload, transportation management and normal seasonal patterns, we expect second quarter 2019 adjusted earnings per diluted share to be fairly consistent with the prior year quarter, based on the favorable impact of earnings contribution from Landair’swarehousing service offerings, partially offset by the unfavorable impact of the slower freight market in general.offerings.
 
In addition to operating ratio, we use "adjusted operating ratio" as a key measure of profitability. Adjusted operating ratio is not a substitute for operating ratio measured in accordance with GAAP. There are limitations to using non-GAAP financial measures. Adjusted operating ratio means operating expenses, net of fuel surcharge revenue, and amortization of intangibles, expressed as a percentage of revenue, excluding fuel surcharge revenue. We believe the use of adjusted operating ratio allows us to more effectively compare periods, while excluding the potentially volatile effect of changes in fuel prices. Our Board and management focus on our adjusted operating ratio as an indicator of our performance from period to period. We believe our presentation of adjusted operating ratio is useful because it provides investors and securities analysts the same information that we use internally to assess our core operating performance. Although we believe that adjusted operating ratio improves comparability in analyzing our period-to-period performance, it could limit comparability to other companies in our industry, if those companies define adjusted operating ratio differently. Because of these limitations, adjusted operating ratio should not be considered a measure of income generated by our business or discretionary cash available to us to invest in the growth of our business. Management compensates for these limitations by primarily relying on GAAP results and using non-GAAP financial measures on a supplemental basis.

Revenue and Expenses
 
We focus on targeted markets throughout the United States where we believe our service standards can provide a competitive advantage. We are a major carrier for transportation companies such as parcel freight forwarders, less-than-truckload carriers, and third-party logistics providers that require a high level of service to support their businesses, as well as for traditional truckload customers such as manufacturers, retailers, and food and beverage shippers. Our four service offerings within the Truckload segment are primarily truckload based and as such we generally dedicate an entire trailer to one customer from origin to destination. We also generate revenue through providing ancillary services, including freight brokerage and logistics services, warehousing, and accounts receivable factoring.
 
We have two reportable segments, our truckload services ("Truckload") and freight brokerage, transportation management services, and shuttle and switching services (“Managed Freight”).
 
The Truckload segment consists of four service offerings that are aggregated because they have similar economic characteristics and meet the aggregation criteria.  The four service offerings that comprise our Truckload segment are as follows: (i) Expedited; (ii) Dedicated; (iii) Temperature-Controlled; and (iv) OTR.
 
In our Truckload segment, we primarily generate revenue by transporting freight for our customers. Generally, we are paid a predetermined rate per mile for our truckload services. We enhance our truckload revenue by charging for tractor and trailer detention, loading and unloading activities, and other specialized services, as well as through the collection of fuel surcharges to mitigate the impact of increases in the cost of fuel. The main factors that could affect our Truckload revenue are the revenue per mile we receive from our customers, the percentage of miles for which we are compensated, and the number of shipments and miles we generate. These factors relate, among other things, to the general level of economic activity in the United States, inventory levels, specific customer demand, the level of capacity in the trucking industry, and driver availability.
 
Our Truckload segment also derives revenue from fuel surcharges, loading and unloading activities, equipment detention, and other accessorial services.  We measure revenue before fuel surcharges, or "freight revenue," because we believe that fuel surcharges tend to be a volatile source of revenue.  We believe the exclusion of fuel surcharges affords a more consistent basis for comparing the results of operations from period-to-period.  Nonetheless, freight revenue represents a non-GAAP financial measure.  Accordingly, undue reliance should not be placed on the discussion of freight revenue, and discussions of freight revenue should be considered in combination with discussions of total revenue.  For each expense item discussed below, we have provided a table setting forth the relevant expense first as a percentage of total revenue, and then as a percentage of freight revenue.

The main expenses that impact the profitability of our Truckload segment are the variable costs of transporting freight for our customers.  These costs include fuel expenses, driver-related expenses, such as wages, benefits, training, and recruitment, and purchased transportation expenses, which primarily include compensating independent contractors.  Expenses that have both fixed and variable components include maintenance and tire expense and our total cost of insurance and claims. These expenses generally vary with the miles we travel, but also have a controllable component based on safety, self-insured retention versus insurance premiums, fleet age, efficiency, and other factors.  Our main fixed costs include rentals and depreciation of long-term assets, such as revenue equipment and terminal facilities, and the compensation of non-driver personnel.
 
Our main measures of profitability are operating ratio and adjusted operating ratio, which we define as operating expenses, net of fuel surcharge revenue, divided by total revenue, less fuel surcharge revenue (or freight revenue) and amortization of intangibles, or freight revenue.intangibles. See page 2022 for the uses and limitations associated with adjusted operating ratio.
 
We operate tractors driven by a single driver and also tractors assigned to two-person driver teams.  Our single driver tractors generally operate in shorter lengths-of-haul, generate fewer miles per tractor, and experience more non-revenue miles, but the lower productive miles are expected to be offset by generally higher revenue per loaded mile and the reduced employee expense of compensating only one driver.  In contrast, our two-person driver tractors generally operate in longer lengths-of-haul, generate greater miles per tractor, and experience fewer non-revenue miles, but we typically receive lower revenue per loaded mile and incur higher employee expenses of compensating both drivers.  We expect operating statistics and expenses to shift with the mix of single and team operations.
 
Managed Freight is comprised primarily of freight brokerage, transportation management services ("TMS"), and shuttle and switching services. Included inThese service offerings are aggregated due to similar margins and customers. Also included within Managed Freight are our warehousing shuttle and switching, and accounts receivable factoring businesses, neither of which do not meetmeets the aggregation criteria,quantitative or qualitative reporting thresholds individually or in the aggregate. but only accounted for $8.3 million, $3.7$16.6 million and $1.8$4.1 million of our revenue, respectively, during the periodsix months ended March 31,June 30, 2019.

Revenue Equipment
 
At March 31,June 30, 2019, we operated 3,103 tractors and 7,0746,921 trailers. Of such tractors, 2,2532,213 were owned, 524562 were financed under operating leases, and 315328 were provided by independent contractors, who provide and drive their own tractors.  Of such trailers, 5,4535,305 were owned, none were1 was financed under an operating leases,lease, and 1,6211,615 were financed under finance type leases.  We finance a small portion of our tractor fleet and larger portion of our trailer fleet with operating leases, which generally run for a period of three to five years for tractors and five to seven years for trailers.  At March 31,June 30, 2019, our fleet had an average tractor age of 2.32.2 years and an average trailer age of 3.94.1 years.
 
Independent contractors provide a tractor and a driver and are responsible for all operating expenses in exchange for a fixed payment per mile.  We do not have the capital outlay of purchasing or leasing the tractor.  The payments to independent contractors and the financing of equipment under operating leases are recorded in revenue equipment rentals and purchased transportation.  Expenses associated with owned equipment, such as interest and depreciation, and expenses associated with employee drivers, including driver compensation, fuel, and other expenses, are not incurred with respect to independent contractors.  Obtaining equipment from independent contractors and under operating leases effectively shifts financing expenses from interest to "above the line" operating expenses, and as such, we evaluate our efficiency using net income margin as well as operating ratio.

For the quarter ended March 31,June 30, 2019, total revenue increased approximately $45.6$23.0 million, or 26.3%11.7%, to $219.2$219.3 million from $173.6$196.3 million in the 2018 quarter. Freight revenue increased approximately $45.3$24.3 million, or 30.1%14.2%, to $195.8$194.9 million for the quarter ended March 31,June 30, 2019, from $150.5$170.6 million in the 2018 quarter, while fuel surcharge revenue increased $0.3decreased $1.3 million quarter-over-quarter. The increase in freight revenue resulted from a $27.5an $18.3 million increase in freight revenue from our Managed Freight segment and a $18.1$6.2 million increase in freight revenue from our Truckload segment.
 
Managed Freight revenue increased $27.5 million quarter-over-quarter, primarily as a result of Landair’s contribution of $20.4 million to combined Managed Freight operations, in addition to growth with existing customers and our focus on growing the offerings within this segment.
The $18.1$6.2 million increase in Truckload revenue relates to a 560486 (or 21.9%18.7%) average tractor increase, offset by a 6.7%12.2% decrease in average freight revenue per tractor per week from the 2018 quarter. Landair contributed $22.7$20.6 million of freight revenue to consolidated Truckload operations for the quarter ended March 31,June 30, 2019, and the July 2018 Landair acquisition was primarily responsible for the increase in average tractors. The decrease in average freight revenue per tractor per week for the quarter ended March 31,June 30, 2019 is the result of a 12.5%an 11.3%  decrease in average miles per unit, partially offset by an 11.6and a 1.8 cents per mile (or 6.6%1.0%increasedecrease in average rate per total mile compared to the 2018 quarter. Landair’s shorter average length of haul and dedicated contract, solo-driven truck operations generally produce higher revenue per loaded mile and fewer miles per unit than our other truckload business units. Team-driven trucks decreased to an average of 863842 teams in the firstsecond quarter of 2019, a decrease of approximately 3.5%4.1% from the average of 894878 teams in the firstsecond quarter of 2018.
 
For the six-month period ended June 30, 2019, total revenue increased $68.6 million, or 18.5%, to $438.5 million from $369.9 million in the 2018 period.  Freight revenue increased $69.6 million, or 21.7%, to $390.7 million for the six months ended June 30, 2019, from $321.1 million in the 2018 period, while fuel surcharge revenue decreased $1.0 million period-over-period. The increase in freight revenue resulted from a $45.5 million increase in freight revenue from our Managed Freight segment, primarily from our Landair acquisition, as well as a $24.1 million increase in freight revenue from our Truckload segment.
The $24.1 million increase in Truckload freight revenue relates to a 523 (or 20.2%) average tractor increase, offset by 9.6% decrease in average freight revenue per tractor per week from the 2019 period.  Landair contributed $40.5 million of freight revenue to the consolidated Truckload operations for the six months ended June 30, 2019 and the July 2018 acquisition was primarily responsible for the increase in average tractors.  The decrease in average freight revenue per tractor per week for the six months ended June 30, 2019 is the result of an 11.9% decrease in average miles per unit partially offset by a 4.8 cents per mile increase in average rate per total mile.  Team driven units decreased approximately 3.7% to an average of 853 for the six-month period ended June 30, 2019 compared to an average of 886 teams during the same 2018 period.
Managed Freight total revenue increased  $18.3 million comparing the 2019 and 2018 quarters, and $45.8 million comparing the 2019 period and 2018 period, primarily as a result of Landair’s contribution of $21.4 million and $41.7 million, respectively, to combined Managed Freight operations, partially offset by a $4.2 million reduction in revenue from our brokerage subsidiary in the 2019 quarter, compared with 2018. Additionally, our brokerage subsidiary contributed $2.0 million more revenue for the six months ended June 30, 2019 compared to the same 2018 period.
Page 20

For comparison purposes in the discussion below, we use total revenue and freight revenue (total revenue less fuel surcharge revenue) when discussing changes as a percentage of revenue. As it relates to the comparison of expenses to freight revenue, we believe removing fuel surcharge revenue, which is sometimes a volatile source of revenue, affords a more consistent basis for comparing the results of operations from period-to-period. Nonetheless, freight revenue represents a non-GAAP financial measure. Accordingly, undue reliance should not be placed on the discussion of freight revenue, and discussions of freight revenue should be considered in combination with discussions of total revenue. For each expense item discussed below, we have provided a table setting forth the relevant expense first as a percentage of total revenue, and then as a percentage of freight revenue.

For the six months ended June 30, 2019, salaries, wages, and related expenses increased approximately $30.0 million, or 24.0%, compared with the same period in 2018.  As a percentage of total revenue, salaries, wages, and related expenses increased to 35.4% of total revenue for the six months ended June 30, 2019, from 33.9% for the six months ended June 30, 2018.  As a percentage of freight revenue, salaries, wages, and related expenses increased to 39.7% of freight revenue for the six months ended June 30, 2019, from 39.0% in the same period in 2018.
These increases are primarily due to increased headcount from the Landair acquisition, as well as driver and non-driver pay increases since the first quarter of 2018.
Page 20

 
When compared to periods prior to the Landair acquisition, we expect salaries, wages and related expenses will be higher as a result of the increased headcount resulting from the Landair acquisition. We believe salaries, wages, and related expenses will increase going forward as a result of a tight driver market, which continues to offer significant challenges, wage inflation, higher healthcare costs, and, in certain periods, increased incentive compensation due to better performance. In particular, we expect driver pay to increase as we look to reduce the number of unseated tractors in our fleet in a tight market for drivers. Future changesAdditionally, as freight market rates continue to driver compensation will be impacted basedincrease, we would expect to, as we have historically, pass a portion of those rate increases on future trends in freight rates.to our professional drivers. Salaries, wages, and related expenses will fluctuate to some extent based on the percentage of revenue generated by independent contractors and our Managed Freight segment, for which payments are reflected in the purchased transportation line item.

Total fuel expense remained relatively even at $29.2 million  for the three months ended June 30, 2019, compared with the same quarter in 2018. As a percentage of total revenue, total fuel expense decreased to 13.3% of total revenue for the three months ended June 30, 2019, from 14.9% in the same quarter in 2018. As a percentage of freight revenue, total fuel expense decreased to 15.0% of freight revenue for the three months ended June 30, 2019, as compared to 17.1% for the 2018 quarter. 
For the six months ended June 30, 2019, total fuel expense increased approximately $0.7 million, or 1.4%, compared with the same period in 2018.  As a percentage of total revenue, total fuel expense decreased to 13.0% of total revenue for the six months ended June 30, 2019, from 15.2% in the 2018 period.  As a percentage of freight revenue, total fuel expense decreased to 14.6% of freight revenue from 17.6% for the six months ended June 30, 2019, compared to the 2018 period. 
 
We receive a fuel surcharge on our loaded miles from most shippers; however, this does not cover the entire increase in fuel prices for several reasons, including the following: surcharges cover only loaded miles we operate; surcharges do not cover miles driven out-of-route by our drivers; and surcharges typically do not cover refrigeration unit fuel usage or fuel burned by tractors while idling. Moreover, most of our business relating to shipments obtained from freight brokers does not carry a fuel surcharge. Finally, fuel surcharges vary in the percentage of reimbursement offered, and not all surcharges fully compensate for fuel price increases even on loaded miles.
 
The rate of fuel price changes also can have an impact on results. Most fuel surcharges are based on the average fuel price as published by the Department of Energy (“DOE”("DOE") for the week prior to the shipment, meaning we typically bill customers in the current week based on the previous week's applicable index. Therefore, in times of increasing fuel prices, we do not recover as much as we are currently paying for fuel. In periods of declining prices, the opposite is true. Ultra low sulfur dieselFuel prices as measured by the DOE remained relatively flat in the firstsecond quarter of 2019 compared with the same quarter in 2018, at $3.02$3.12 per gallon.gallon and decreased to $3.07 from $3.18 for the six months ended June 30, 2019 and 2018 respectively.
 
To measure the effectiveness of our fuel surcharge program, we subtract fuel surcharge revenue (other than the fuel surcharge revenue we reimburse to independent contractors and other third parties which is included in purchased transportation) from our fuel expense.  The result is referred to as net fuel expense.  Our net fuel expense as a percentage of freight revenue is affected by the cost of diesel fuel net of fuel surcharge revenue, the percentage of miles driven by company tractors, our fuel economy, our percentage of deadhead miles, for which we do not receive material fuel surcharge revenues, and the net impact of fuel hedging gains and losses.  Net fuel expense is shown below:

Total fuel expense increased approximately $0.7 million, or 2.4%, for the three months ended March 31, 2019, compared with the same quarter in 2018. As a percentage of total revenue, total fuel expense decreased to 12.7% of total revenue for the three months ended March 31, 2019, from 15.7% in the same quarter in 2018. As a percentage of freight revenue, total fuel expense decreased to 14.2% of freight revenue for the three months ended March 31, 2019, as compared to 18.1% for the 2018 quarter. These changes in total fuel expense as a percentage of total revenue for the quarter ended March 31, 2019 are primarily due the aforementioned increases in average rate per total mile, as the average price per gallon of ultra-low sulfur diesel as measured by the DOE remained relatively flat.

The change in net fuel expense is primarily due to a greater percentagelack of miles driven by independent contractors, where we pay a ratethe favorable fuel hedging activity that reflects then-existingwas present in the 2018 periods.  We have not had any fuel prices and we do not have the natural hedge created by fuel surcharge. The increases were partially offset by brokering less freight and the tiered reimbursement structure of certain fuel surcharge agreements.hedges in place since December 2018.
 
We expect to continue managing our idle time and tractor speeds, investing in more fuel-efficient tractors to improve our miles per gallon, locking in fuel hedges when deemed appropriate, and partnering with customers to adjust fuel surcharge programs that are inadequate to recover a fair portion of fuel costs. Going forward, our net fuel expense is expected to fluctuate as a percentage of revenue based on factors such as diesel fuel prices, percentage recovered from fuel surcharge programs, percentage of uncompensated miles, percentage of revenue generated by team-driven tractors (which tend to generate higher miles and lower revenue per mile, thus proportionately more fuel cost as a percentage of revenue), percentage of revenue generated by refrigerated operation (which uses diesel fuel for refrigeration, but usually does not recover fuel surcharges on refrigeration fuel), percentage of revenue generated from independent contractors, and the success of fuel efficiency initiatives.
Page 22

Given recent historical lows, we would expect diesel fuel prices to increase over the next few years. However, we expect to continue to experience improved fuel economy as we upgrade our tractor fleet, and while our fuel surcharge recovery has remained relatively flat, the possibility of further improvement exists if efforts to grow our dedicated business are successful.

These increases were primarily the result of the acquisition of Landair and its respective higher average age of tractor and trailer equipment.

Going forward, we believe this category will fluctuate based on several factors, including expected upgrades to Landair’s fleet, our continued ability to maintain a relatively young fleet in our other operating companies, accident severity and frequency, weather, and the reliability of new and untested revenue equipment models.

These increases were primarily the result of the acquisition of Landair's managed freight business, which added to overall purchased transportation cost but at a lower percentage than the historic business.is less reliant on purchased transportation to generate revenue, compared to our existing brokerage and logistics services. Additionally, we experienced increases due to a more competitive market for sourcing third-party capacity in our existing Managed Freight segment.

Further, the percentage of the total miles run by independent contractors increased from 11.0% and 11.9% for the three and six months ended June 30, 2018, quarterrespectively, to 12.6% and 12.8% for the same 2019 quarter. periods.
We expect revenue equipment rentals to decrease going forward as a result of our increase in acquisition of revenue equipment through finance leases rather than operating leases, particularly as we transition Landair from operating leases to owned equipment. As discussed below, this decrease may be partially or fully offset by an increase in purchased transportation, as we expect to continue to grow our Managed Freight segment, as well as a result of reduced capacity.
Page 22

 
We expect purchased transportation to increase as we seek to grow our Managed Freight segment. In addition, if fuel prices increase, it would result in a further increase in what we pay third party carriers and independent contractors. However, this expense category will fluctuate with the number and percentage of loads hauled by independent contractors, loads handled by Managed Freight, and tractors, trailers, and other assets financed with operating leases. In addition, factors such as the cost to obtain third party transportation services and the amount of fuel surcharge revenue passed through to the third party carriers and independent contractors will affect this expense category. If industry-wide trucking capacity were to tighten in relation to freight demand, we may need to increase the amounts we pay to third-party transportation providers and independent contractors, which could increase this expense category on an absolute basis and as a percentage of freight revenue absent an offsetting increase in revenue. We continue to actively recruit independent contractors and, if we are successful, we would expect this line item to increase as a percentage of revenue.

Insurance and claims, consisting primarily of premiums and deductible amounts for liability, physical damage, and cargo damage insurance and claims, increased approximately $2.6$0.6 million, or 29.4%5.7%  for the three months ended March 31,June 30, 2019 compared with the same quarter in 2018. As a percentage of total revenue, insurance and claims increaseddecreased to 5.1%4.8% of total revenue for the  three months ended March 31,June 30, 2019, from 5.0% in the same quarter in 2018.

Insurance and claims per mile cost increased to 13.9remained relatively even at 12.4 cents per mile in the firstsecond quarter of 2019 from 11.6compared to 12.6 cents per mile in the firstsecond quarter of 2018.
For the six months ended June 30, 2019, insurance and claims increased approximately $3.1 million, or 16.7%, compared with the same period in 2018.  As a percentage of total revenue, insurance and claims remained flat at 5.0% of total revenue for the six months ended June 30, 2019 compared to the same 2018 period. As a percentage of freight revenue, insurance and claims decreased slightly to 5.6% of freight revenue for the six months ended June 30, 2019, compared to 5.8% for the same period in 2018. Insurance and claims cost per mile increased to 13.1 cents per mile in the six months ended June 30, 2019 from 12.1 cents per mile in the same 2018 period. The per mile increase is primarily the result of development on prior period claims during the threesix months ended March 31,June 30, 2019, partially offset by decreased frequency of accidents compared to the same 2018 period. Our rate of chargeable accidents per million miles, as measured by the U.S. Department of Transportation, decreased by 13.0% in8.0% for the six months ended June 30, 2019 compared to the same 2018 period.
Our auto liability (personal injury and property damage), cargo, and general liability insurance programs include significant self-insured retention amounts. We are also self-insured for physical damage to our equipment. Because of these significant self-insured exposures, insurance and claims expense may fluctuate significantly from period-to-period. Any increase in frequency or severity of claims, or any increases to then-existing reserves, could adversely affect our financial condition and results of operations. We periodically evaluate strategies to efficiently reduce our insurance and claims expense. The auto liability policy contains a feature whereby we are able to retroactively obtain a partial refund of the premium in exchange for taking on the liability for incidents that occurred during the period and releasing the insurers. This is referred to as "commuting" the policy or "policy commutation." In several past periods we have commuted the policy, which has lowered our insurance and claims expense. We intend to evaluate our ability to commute the current policy and any such commutation could significantly impact insurance and claims expense. Our prior auto liability policy that ran from October 1, 2014 through March 31, 2018, included a commutation provision if we were to commute the policy for the entire 42 months. Based on claims paid to date the policy premium release refund could range from zero to $4.9 million, depending on actual claims settlements in the future. Effective April 2018, we entered into new auto liability policies with a three-year term. The policy includes a limit for a single loss of $9.0 million, an aggregate of $18.0 million for each policy year, and a $30.0 million aggregate for the 36 month term ended March 31, 2021. The policy includes a policy release premium refund or commutation option of up to $14.0 million, less any future amounts paid on claims by the insurer. A decision with respect to commutation of the policy could be made before April 1, 2021. Management cannot predict whether or not future claims or the development of existing claims will justify a commutation of either policy period, and accordingly, no related amounts were recorded at March 31,June 30, 2019.

Depreciation and amortization, including gains and losses on disposition of property and equipment ("depreciation and amortization"), consists primarily of depreciation of tractors, trailers, and other capital assets offset or increased, as applicable, by gains or losses on dispositions of capital assets, as well as amortization of intangible assets.  Depreciation and amortization increased by less than $0.1$2.7 million, or 0.1%15.1%, for the three months ended March 31,June 30, 2019, compared with the same quarter in 2018.

We expect depreciation and amortization, including amortization of intangible assets, to remain relatively consistent going forward. However, if the used tractor market were to decline, we could have to adjust residual values and increase depreciation or experience increased losses on sale.

These decreases were primarily related to the $5.4 million and $5.3 million decreases in the pre-tax income in the three- and six-month periods ended June 30, 2019, respectively, compared to the same 2018 periods, resulting from the decline in operating income as discussed above, partially offset by the contribution from TEL’s earnings noted above.
Page 26

The effective tax rate is different from the expected combined tax rate due primarily to permanent differences related to our per diem pay structure for drivers. Due to the partial nondeductible effect of the per diem payments, our tax rate will fluctuate in future periods as income fluctuates. We are currently estimating our 2019 effective income tax rate to be approximately 27.1%27.6%.
  
RESULTS OF SEGMENT OPERATIONS
 
We have two reportable segments, truckload services, which we refer to as Truckload, and Managed Freight. Our Managed Freight segment has service offerings ancillary to our Truckload services, including: freight brokerage service provided both directly and through freight brokerage agents, who are paid a commission for the freight they provide, transportation management services, and shuttle and switching services. These operations consist of several operating segments, whichservice offerings are aggregated due to similar margins and customers. Included inAlso included within Managed Freight are our warehousing shuttle and switching, and accounts receivable factoring businesses, neither of which do not meetmeets the aggregation criteria,quantitative or qualitative reporting thresholds individually or in the aggregate, but only accountedaccount for $8.3 million, $3.7$16.6 million and $1.8$4.1 million of our 2019 revenue, respectively, during the period ended March 31, 2019.respectively.

For the 2019 quarter, Truckload total revenue increased $18.1 million due to a $18.0The $6.2 million increase in freightTruckload revenue as well as a $0.1 million increase in fuel surcharge revenue. The increase in freight revenue primarily relates to a 560486 (or 21.9%18.7%) average tractor increase, offset by a 6.7%12.2% decrease in average freight revenue per tractor per week from the 2018 quarter. Landair contributed $22.7$20.6 million of freight revenue to consolidated Truckload operations for the quarter ended March 31,June 30, 2019, and the July 2018 acquisition was primarily responsible for the increase in average tractors. The decrease in average freight revenue per tractor per week for the quarter ended March 31,June 30, 2019 is the result of a 12.5%an 11.3% decrease in average miles per unit, partially offset by an 11.6and a 1.8 cents per mile (or 6.6%1.0%increasedecrease in average rate per total mile compared to the 2018 quarter. Landair’s shorter average length of haul and dedicated contract, solo-driven truck operations generally produce higher revenue per loaded mile and fewer miles per unit than our other truckload services. Team-driven trucks decreased to an average of 870842 teams in the firstsecond quarter of 2019, a decrease of approximately 2.7%4.1% from the average of 894878 teams in the firstsecond quarter of 2018.
For the six-month period ended June 30, 2019, total revenue increased $68.6 million, or 18.5%, to $438.5 million from $369.9 million in the 2018 period.  Freight revenue increased $69.6 million, or 21.7%, to $390.7 million for the six months ended June 30, 2019, from $321.1 million in the 2018 period, while fuel surcharge revenue decreased $1.0 million period-over-period. The increase in freight revenue resulted from a $45.8 million increase in revenue from our Managed Freight segment, as well as a $24.1 million increase in freight revenue from our Truckload segment.
The $24.1 million increase in Truckload freight revenue relates to a 523 (or 20.2%) average tractor increase, offset by 9.6% decrease in average freight revenue per tractor per week from the 2019 year-to-date period.  Landair contributed $40.5 million of freight revenue to the consolidated Truckload operations for the six months ended June 30, 2019 and the July 2018 acquisition was primarily responsible for the increase in average tractors.  The decrease in average freight revenue per tractor per week for the six months ended June 30, 2019 is the result of an 11.9% decrease in average miles per unit partially offset by a 4.8 cents per mile increase in average rate per total mile.  Team driven units decreased approximately 3.7% to an average of 853 for the six-month period ended June 30, 2019 compared to an average of 886 teams during the same 2018 period.
 
Our Truckload operating income was $4.1$6.6 million and $10.6 million lower in the 2019 quarter and six months ended June 30, 2019 than in the same 2018 quarter,periods, due to an increase in operating costs per mile, net of fuel surcharge revenue, primarily related to the abovementioned increases in salaries and driver compensation and insurance and claims expense, as well as increases in purchased transportation. These increases were partially offset by increases in revenue.

LIQUIDITY AND CAPITAL RESOURCES
 
Our business requires significant capital investments over the short-term and the long-term. Recently, we have financed our capital requirements with borrowings under our Credit Facility, cash flows from operations, long-term operating leases, finance leases, secured installment notes with finance companies, and proceeds from the sale of our used revenue equipment. Going forward, we expect revenue equipment acquisitions through purchases and financecapital leases to increase as a percentage of our fleet as we decrease our use of operating leases. Further, we expect to increase our capital allocation toward dedicated, transportation management services, and other managed freight solutions to become the go-to partner for our customers’ most critical transportation and logistics needs. We had working capital (total current assets less total current liabilities) of $92.8$92.9 million and $84.3 million at March 31,June 30, 2019 and December 31, 2018, respectively. Our working capital on any particular day can vary significantly due to the timing of collections and cash disbursements. Based on our expected financial condition, net capital expenditures, results of operations, related net cash flows, installment notes, and other sources of financing, we believe our working capital and sources of liquidity will be adequate to meet our current and projected needs and we do not expect to experience material liquidity constraints in the foreseeable future.
 
We expect borrowings from the financial affiliates of our primary revenue equipment suppliers to be available to fund most new tractors expected to be delivered in 2019, while any other property and equipment purchases, including trailers, are expected to be funded with a combination of notes, operating leases, finance leases, and/or from the Credit Facility. With a relatively young average fleet age at March 31,June 30, 2019, we believe we have flexibility to manage our fleet, and we plan to regularly evaluate our tractor replacement cycle, new tractor purchase requirements, and purchase options. If we are successful in our attempts to grow our independent contractor fleet, our capital requirements would be reduced. Our current tractor fleet plan for full-year 2019 includes the delivery of approximately 1,165 new company tractors and the disposal of approximately 1,200 used tractors. Over the course of 2019, the size of our tractor fleet is expected to be flat to down 2.0% compared to the 3,154 tractors we operated as of December 31, 2018, depending on our ability to secure additional long-term dedicated contracts from shippers and our ability to hire and retain professional drivers to seat our tractors. As of March 31,June 30, 2019, we had $29.6$17.3 million of borrowings outstanding, undrawn letters of credit outstanding of approximately $33.4$34.8 million, and available borrowing capacity of $32.0$42.9 million under the Credit Facility. Fluctuations in the outstanding balance and related availability under our Credit Facility are driven primarily by cash flows from operations and the timing and nature of property and equipment additions that are not funded through notes payable, as well as the nature and timing of collection of accounts receivable, payments of accrued expenses, and receipt of proceeds from disposals of property and equipment. Unless we decide to make any strategic investments during the year, we anticipate paying off an aggregate of approximately $40.0 to $60.0 million of financing and lease liabilities, comprised of both on and off balance sheet obligations, during 2019. Refer to Note 5, “Debt” of the accompanying consolidated financial statements for further information about material debt agreements.
 
Cash Flows
 
Net cash flows provided by operating activities decreased $27.5$39.0 million infor the quartersix-month period ended March 31,June 30, 2019 compared with the same 2018 quarter,period, primarily due to increases in receivables and driver advances resulting from growth of receivables purchased by our factoring division, fluctuations in cash flows from accounts payable and accrued expenses, which primarily related to the timing and amount of payments on our accrued expenses and trade accounts in the 2019 quarterperiod compared to the same 2018 quarter,period, as well as the timingreduction of paymentreceivables related to reduced total revenue in our Truckload segment partially offset by the receivables for Landair as a result of insurance claims affectingthe July 2018 acquisition. These decreases were partially offset by the growth of receivables purchased by our insurance and claims accrual.

The change in net cash flows used by investing activities was primarily the result of the timing of our trade cycle whereby we took delivery of approximately 209726 new company tractors and disposed of approximately 40304 used tractors in the 2019 quarterperiod compared to delivery and disposal of approximately 286394 and 252465 tractors, respectively in the same 2018 period.

The preparation of financial statements in conformity with accounting principles generally accepted in the U.S. 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 affect the outcomes of our estimates and assumptions. Accordingly, actual results could differ from those anticipated. There have been no material changes to our most critical accounting policies and estimates during the three and six months ended March 31,June 30, 2019, compared to those disclosed in Item 7, "Management's Discussion and Analysis of Financial Condition and Results of Operations," included in our 2018 Annual Report on Form 10-K, other than adoption of Topic 842, Leases, as discussed in Note 1, “Significant Accounting Policies” of the accompanying consolidated financial statements.10-K.
 
ITEM 3.
QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
 
We experience various market risks, including changes in interest rates and fuel prices. We do not enter into derivatives or other financial instruments for trading or speculative purposes, or when there are no underlying related exposures. Because our operations are mostly confined to the United States, we are not subject to a material amount of foreign currency risk.
 
COMMODITY PRICE RISK
 
We engage in activities that expose us to market risks, including the effects of changes in fuel prices and in interest rates. Financial exposures are evaluated 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 have on operating results.
 
In an effort to seek to reduce the variability of the ultimate cash flows associated with fluctuations in diesel fuel prices, we have periodically entered into various derivative instruments, including forward futures swap contracts. We have historically entered into hedging contracts with respect to ultra low sulfur diesel (“ULSD”("ULSD"). Under these contracts, we paid a fixed rate per gallon of ULSD and received the monthly average price of Gulf Coast ULSD. The retrospective and prospective regression analyses provided that changes in the prices of diesel fuel and ULSD were deemed to be highly effective based on the relevant authoritative guidance. At March 31,June 30, 2019, there are no remaining fuel hedge contracts. We do not engage in speculative transactions, nor do we hold or issue financial instruments for trading purposes.


A one dollar increase in the price of diesel per gallon would decrease our net income by $4.7$2.8 million. This sensitivity analysis considers that we expect to purchase approximately 40.923.3 million gallons of diesel during the remainder of 2019, with an assumed fuel surcharge recovery rate of  84.1%83.5% of the cost (which was our fuel surcharge recovery rate during the quartersix-months ended March 31,June 30, 2019).
Page 27

 
INTEREST RATE RISK
 
In August 2015, we entered into an interest rate swap agreement with a notional amount of $28.0 million, which was designated as a hedge against the variability in future interest payments due on the debt associated with the purchase of our corporate headquarters. The terms of the swap agreement effectively convert the variable rate interest payments on this note to a fixed rate of 4.2% through maturity on August 1, 2035. In 2016 and 2017, we also entered into several other interest rate swaps, which were designated to hedge against the variability in future interest rate payments due on rent associated with the purchase of certain trailers. Because the critical terms of the swap and hedged items coincide, in accordance with the requirements of ASC 815, the change in the fair value of the derivative is expected to exactly offset changes in the expected cash flows due to fluctuations in the LIBOR rate over the term of the debt instrument, and therefore no ongoing assessment of effectiveness is required. The fair value of all interest rate swap agreements that were in effect at MarchJune 30, 2019 and December 31, 2019,2018 of approximately $1.3 million and $0.3 million, isrespectively, are included in other short and long-term assets and other short and long-term liabilities, as appropriate based upon each swap agreement's position, in the condensed consolidated balance sheet and is included in Accumulatedaccumulated other comprehensive (loss) income, net of tax. Additionally, less than $0.1 million was reclassified from accumulated other comprehensive income into our results of operations as additional interest expense for the three and six months ended March 31,June 30, 2019, respectively, related to changes in interest rates during such quarter.periods. Based on the amounts in accumulated other comprehensive income as of March 31,June 30, 2019, we expect to reclassify losses of approximately less than $0.1 million, net of tax, on derivative instruments from accumulated other comprehensive income into our results of operations during the next twelve months due to changes in interest rates. The amounts actually realized will depend on the fair values as of the date of settlement.
Page 29

Our market risk is also affected by changes in interest rates. Historically, we have used a combination of fixed-rate and variable-rate obligations to manage our interest rate exposure. Fixed-rate obligations expose us to the risk that interest rates might fall. Variable-rate obligations expose us to the risk that interest rates might rise. Of our total $310.0$323.3 million of debt and operating and finance leases, we had $62.6$49.8 million of variable rate debt outstanding at March 31,June 30, 2019, including our Credit Facility, a real-estate note and certain equipment notes, of which the real-estate note of $24.6$24.3 million was hedged with the interest rate swap agreement at 4.2% and certain of our equipment notes totaling $8.5$8.2 million were hedged to provide a weighted average interest rate of 2.0%. The interest rates applicable to these agreements are based on either the prime rate or LIBOR. Our earnings would be affected by changes in these short-term interest rates. Risk can be quantified by measuring the financial impact of a near-term adverse increase in short-term interest rates. At our March 31,June 30, 2019 level of borrowing, a 1% increase in our applicable rate would reduce annual net income by less thanapproximately $0.1 million. Our remaining debt is fixed rate debt, and therefore changes in market interest rates do not directly impact our interest expense.
ITEM 4.     CONTROLS AND PROCEDURES
 
Evaluation of Disclosure Controls and Procedures

We have established disclosure controls and procedures to ensure that material information relating to us and our consolidated subsidiaries is made known to the officers who certify our financial reports and to other members of senior management and the Board of Directors.

As of the end of the period covered by this report, we carried out an evaluation, under the supervision and with the participation of our management, including the Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operations of our disclosure controls and procedures (as defined in Rule 13a-15(e) and 15d-15(e) under the Exchange Act). Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that due to a material weakness in our internal control over financial reporting described in Item 9A of our Annual Report on Form 10-K for the fiscal year ended December 31, 2018, our disclosure controls and procedures were not effective as of March 31,June 30, 2019.

Notwithstanding the identified material weakness, management believes the consolidated financial statements included in this Form 10-Q fairly present, in all material respects, our financial condition, results of operations and cash flows as of and for the periods presented in accordance with U.S. generally accepted accounting principles.

Remediation

Management has been implementing and continues to implement measures designed to ensure that control deficiencies contributing to the material weakness are remediated, such that these controls are designed, implemented, and operating effectively. In accordance with our remediation plan, we have and will continue to (i) develop a training program addressing ITGCs and policies, including educating control owners concerning the principles and requirements of each control, with a focus on those related to change-management over IT systems impacting financial reporting; (ii) implement controls to address and maintain documentation of completeness and accuracy of system generated information used to support the operation of the controls; (iii) develop enhanced change-management intake procedures and controls related to changes in IT systems; (iv) implement an IT management review and testing plan to monitor ITGCs with a specific focus on systems supporting our financial reporting processes; and (v) enhance monthly reporting on the remediation measures to the Audit Committee of our Board of Directors.
Page 28


As of March 31,June 30, 2019, we have taken substantial action to implement our remediation plan. We have started developing a training program to address ITGCs and related policies. Management has implemented controls to address system generated information, which includes additional testing of financially significant reports and interfaces before any related changes are made to the underlying systems, reports, or data. To address intake procedures, we have added additional procedures to identify changes that could impact systems, data or reports that are financially significant. We have key personnel reviewing information technology management review and testing plans to monitor ITGCs. Finally, management has enhanced reporting to the Audit Committee of our Board of Directors by reviewing the Company’s remediation efforts with Audit Committee members during each of the threesix months in first quarter fiscal 2019. We believe that these actions will remediate the material weakness. The material weakness will not be considered remediated, however, until the applicable controls operate for a sufficient period of time and management has concluded, through testing, that these controls are operating effectively. We expect that the remediation of this material weakness will be completed prior to the end of fiscal 2019.

Changes in Internal Control Over Financial Reporting

Other than the remediation process described above, the implementation of controls that may materially affect internal controls related to Landair, and the implementation of controls related to our adoption of Topic 842, Leases, there have been no other changes in our internal control over financial reporting (as defined in Rules 13a-15(f) or 15d-15(f) of the Exchange Act) that occurred during the first quarter of fiscalthree months ended June 30, 2019 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

Page 30

Our management, including our Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure procedures and controls or our internal controls will prevent all errors or intentional fraud. An internal control system, no matter how well-conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of such internal controls are met.  Further, the design of an internal controls system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs.  Due to the inherent limitations in all internal controls systems, no evaluation of controls can provide absolute assurance that all our controls issues and instances of fraud, if any, have been detected.

ITEM 1.
LEGAL PROCEEDINGS
 
From time-to-time, we are a party to ordinary, routine litigation arising in the ordinary course of business, most of which involves claims for personal injury and/or property damage incurred in connection with the transportation of freight.
Our subsidiary Covenant Transport, Inc. (“Covenant Transport”) is a defendant in a lawsuit filed on November 9, 2018, in the Superior Court of Los Angeles County, California. The lawsuit was filed on behalf of Richard Tabizon (a California resident and former driver) who is seeking to have the lawsuit certified as a class action. The complaint asserts that the time period covered by the lawsuit is from October 31, 2014 to the present and alleges claims for failure to properly pay for rest breaks, failure to provide accurate itemized wage statements and/or reimbursement of business related expenses, unlawful deduction of wages, failure to pay proper minimum wage and overtime wages, failure to provide all wages due at termination, and other related wage and hour claims under the California Labor Code. Since the original filing date, the case has been removed from the Los Angeles Superior Court to the U.S. District Court in the Central District of California and subsequently the case was transferred to the U.S. District Court in the Eastern District of Tennessee where the case is now pending. We do not currently have enough information to make a reasonable estimate as to the likelihood, or amount of a loss, or a range of reasonably possible losses as a result of this claim, as such there have been no related accruals recorded as of June 30, 2019. 
Also, in February, 2019, Covenant Transport was named in a separate (but related) lawsuit filed in the Superior Court of Los Angeles County, California requesting civil penalties under the California Private Attorneys’ General Act for the same underlying wage and hour claims at issue in the putative class action case noted above. On August 1, 2019, the Los Angeles Superior Court entered an order staying the action pending completion of the earlier-filed action that is pending in the United States District Court for the Eastern District of Tennessee. We do not currently have enough information to make a reasonable estimate as to the likelihood, or amount of a loss, or a range of reasonably possible losses as a result of this claim, as such there have been no related accruals recorded as of June 30, 2019. 
 
We maintain insurance to cover liabilities arising from the transportation of freight for amounts in excess of certain self-insured retentions. In management's opinion, our potential exposure under pending legal proceedings is adequately provided for in the accompanying consolidated financial statements.
 
Based on our present knowledge of the facts and, in certain cases, advice of outside counsel, management believes the resolution of open claims and pending litigation, taking into account existing reserves, is not likely to have a materially adverse effect on our consolidated financial statements.
 
ITEM 1A.
RISK FACTORS
 
While we attempt to identify, manage, and mitigate risks and uncertainties associated with our business, some level of risk and uncertainty will always be present.  Our Form 10-K for the year ended December 31, 2018, in the section entitled "Item 1A. Risk Factors," describes some of the risks and uncertainties associated with our business.  These risks and uncertainties have the potential to materially affect our business, financial condition, results of operations, cash flows, projected results, and future prospects.
 
ITEM 2.
UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS
 
During the quarter ended March 31,June 30, 2019, we did not engage in unregistered sales of securities or any other transactions required to be reported under this Item 2 of Part II on Form 10-Q.

The payment of cash dividends is currently limited by our financing arrangements, including certain covenants under our Credit Facility.
