The accompanying unaudited consolidated condensed financial statements have been prepared in accordance with U.S. generally accepted accounting principles for interim financial statements, and therefore do not include all information and disclosures required by U.S. generally accepted accounting principles for complete financial statements. In the opinion of management, such statements reflect all adjustments (consisting of normal recurring adjustments) considered necessary to fairly present our consolidated financial condition, results of operations and cash flows for the interim periods presented. The results of operations for any interim period do not necessarily indicate the results for the full year. The unaudited interim consolidated condensed financial statements should be read with reference to the consolidated financial statements and notes to consolidated financial statements in our ~~2014~~2015 Annual Report on Form 10-K.

Unvested performance unit awards totaling ~~48,861~~57,205 and ~~35,964~~48,861 equivalent shares for the three-month periods ended March 31, ~~2015~~2016 and March 31, ~~2014,~~2015, respectively, were considered outstanding but were not included in the calculation of diluted earnings per share because inclusion of average unrecognized compensation expense in the calculation would cause the performance units to be antidilutive.

(3)	~~(3)~~ Long-Term Debt

We maintain a credit agreement that provides for an unsecured committed credit facility which matures in December 2019. ~~The~~In November 2015, we entered into an amendment to the facility which increased the aggregate principal amount of the ~~credit~~ facility offrom $50.0 million ~~may be increased at our option, subject~~ to ~~completion of signed amendments with the lender, up to a maximum aggregate principal amount of~~ $75.0 million. At March 31, ~~2015,~~2016, there was no outstanding principal balance on the ~~credit~~ facility. As of that date, we had outstanding standby letters of credit of ~~$9.2~~$8.6 million and remaining borrowing availability of ~~$40.8~~$66.4 million. At December 31, 2015, there was an outstanding principal balance of $37.9 million on the facility. This facility bears interest at a variable rate based on the London Interbank Offered Rate or the lender’s Prime Rate, in each case plus/minus applicable margins. The weighted average interest rate for the facility was ~~0.84%~~1.1% at December 31, ~~2014,~~2015.

Our credit facility prohibits us from paying, in any fiscal year, stock redemptions and dividends in excess of 25% of our net income from the ~~last quarter-end date~~prior fiscal year. A waiver of the 25% limitation for 2015 and 2016, should it apply, was obtained from the lender. This facility also contains restrictive covenants which, among other matters, require us to maintain compliance with ~~an outstanding principal balance.~~

cash flow leverage and fixed charge coverage ratios. We were in compliance with all covenants at March 31, 2016 and December 31, 2015.

(4)	~~(4)~~ Related Party Transactions

We purchase fuel and ~~obtain~~ tires and obtain related services from Bauer Built, Inc., or BBI. Jerry M. Bauer, one of our directors, is the chairman of the board, ~~and~~ chief executive officer and the principal stockholder of BBI. We paid BBI $62,000 in the first three months of 2016 and $55,000 in the first three months of 2015 for fuel, tires and ~~$138,000~~related services. In addition, we paid $479,000 in the first three months of ~~2014 for fuel~~2016 and ~~tire services. In addition, we paid~~ $219,000 in the first three months of 2015 ~~and $238,000 in the first three months of 2014~~ to tire manufacturers for tires that were provided by BBI. BBI received commissions from the tire manufacturers related to these purchases.

We provide transportation services to MW Logistics, LLC (MWL) as described in Note 7.

(5)	Share Repurchase Program

~~(5) Dividends~~

In December 2007, our Board of Directors approved and we announced a share repurchase program to repurchase up to one million shares of our common stock either through purchases on the open market or through private transactions and in accordance with Rule 10b-18 of the Exchange Act. On November 4, 2015, our Board of Directors approved and we announced an increase in the share repurchase program, providing for the repurchase of up to $40 million, or approximately 2 million shares, of our common stock. The timing and extent to which we repurchase shares depends on market conditions and other corporate considerations. The repurchase program does not have an expiration date.

In the fourth quarter of 2015 we repurchased and retired 941,024 shares of our common stock for $16.2 million. We repurchased and retired 455,581 shares of our common stock for $7.5 million in the first quarter of 2016.

(7)	~~(6)~~ Accounting for Share-based Payment Arrangement Compensation

We account for share-based payment arrangements in accordance with Financial Accounting Standards Board Accounting Standards Codification, or FASB ASC, 718,Compensation – Stock Compensation. During the first three months of ~~2015,~~2016, there were no significant changes to the structure of our stock-based award plans. Pre-tax compensation expense related to stock options and performance unit awards recorded in the first three months of 2016 and 2015 was $290,000 and ~~2014 was~~ $273,000, ~~and $211,000,~~ respectively. See Note 1113 to our consolidated financial statements in our ~~2014~~2015 Annual Report on Form 10-K for a detailed description of stock-based ~~awards under our 2005 Stock Incentive Plan.~~awards.

(10)	~~(9)~~ Commitments and Contingencies

We are committed to purchase ~~$67.8~~$122.1 million of new revenue equipment in the remainder of ~~2015;~~2016; building construction expenditures of ~~$4.9~~$1.2 million in the remainder of ~~2015;~~2016; and operating lease obligation expenditures totaling ~~$759,000~~$369,000 through 2018.

We self-insure, in part, for losses relating to workers’ compensation, auto liability, general liability, cargo and property damage claims, along with employees’ health insurance with varying risk retention levels. We maintain insurance coverage for per-incident and total losses in excess of these risk retention levels in amounts we consider adequate based upon historical experience and our ongoing review, and reserve currently for the estimated cost of the uninsured portion of pending claims.

We are also involved in other legal actions that arise in the ordinary course of business. In the opinion of management, based upon present knowledge of the facts, it is remote that the ultimate outcome of any such legal actions will have a material adverse effect upon our long-term financial position or results of operations.

(11)	~~(10)~~ Business Segments

We have ~~six~~aggregated our five current operating segments ~~that have been aggregated~~ into four reporting segments (Truckload, Dedicated, Intermodal and Brokerage) for financial reporting ~~purposes. Information for the first quarter of 2014, which was previously aggregated into two reporting segments, has been shown in the same four segments for comparison~~ purposes.

The primary source of our operating revenue is provided by our Truckload segment through a combination of regional short-haul and medium-to-long-haul full-load transportation services. We transport food and other consumer packaged goods that require a temperature-controlled or insulated environment across the United States and into and out of Mexico and Canada.

Our Dedicated segment provides customized transportation solutions tailored to meet individual customers’ requirements, utilizing temperature-controlled trailers, dry vans and other specialized equipment within the United States. Our customer contracts range from three to five years and are subject to annual rate reviews.

Our Intermodal segment transports our customers’ freight within the United States primarily utilizing our temperature-controlled trailers and also, through March 2015, our dry containers on railroad flatcars for portions of trips, with the balance of the trips using our tractors or, to a lesser extent, contracted carriers.

The following table sets forth for the periods indicated our operating revenue and operating income by segment. We do not prepare separate balance sheets by segment and, as a result, assets are not separately identifiable by segment.

In February 2016, the FASB issued Accounting Standards Update No. 2016-02, “Leases” which requires organizations that lease assets to recognize on the balance sheet the assets and liabilities for the rights and obligations created by those leases. The new guidance also requires additional disclosures related to leasing transactions. The standard is effective for the first quarter of 2019. The adoption of this standard is not expected to have a significant impact on our consolidated condensed balance sheets, statements of operations or statements of cash flows.

In March 2016, the FASB issued Accounting Standards Update No. 2016-09, “Compensation - Stock Compensation: Improvements to Employee Share-Based Payment Accounting” which simplifies several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities and classification on the statement of cash flows. The standard is effective for the first quarter of 2017. The adoption of this standard will result in an increase or decrease to our provision for income taxes each quarter based on the actual increase in our stock price compared with the grant-date fair value of the quarter’s exercised options and vested performance unit awards. The adoption of the other provisions of this standard is not expected to have a significant impact on our consolidated condensed balance sheets, statements of operations or statements of cash flows.

Item 2. Management’s Discussion and Analysis of Financial Condition andResults of Operations.

The following discussion and analysis of our financial condition and results of operations should be read together with the selected consolidated financial data and our consolidated condensed financial statements and the related notes appearing elsewhere in this report. This discussion and analysis contains forward-looking statements that involve risks, uncertainties and assumptions. Our actual results may differ materially from those anticipated in these forward-looking statements as a result of many factors, including but not limited to those included in our Form 10-K, Part 1, Item 1A for the year ended December 31, 20145. We do not assume, and specifically disclaim, any obligation to update any forward-looking statement contained in thisreport.

Generally, we are paid by the mile for our Truckload and Dedicated services. We also derive Truckload and Dedicated revenue from fuel surcharges, loading and unloading activities, equipment detention and other ancillary services. The main factors that affect our Truckload and Dedicated revenue are the rate per mile we receive from our customers, the percentage of miles for which we are compensated, the number of miles we generate with our equipment and changes in fuel prices. We monitor our revenue production primarily through average Truckload and Dedicated revenue, net of fuel surcharges, per tractor per week. We also analyze our average Truckload and Dedicated revenue, net of fuel surcharges, per total mile, non-revenue miles percentage, the miles per tractor we generate, our fuel surcharge revenue, our accessorial revenue and our other sources of operating revenue.

Our Brokerage segment arranges for smaller third-party carriers to transport freight for our customers in temperature-controlled trailers and dry vans within the United States and into and out of Mexico while we retain the billing, collection and customer management responsibilities. The main factors that affect our Brokerage revenue are the rate per mile and other charges we receive from our customers.

In addition to the factors discussed above, our operating revenue is also affected by, among other things, the United States economy, inventory levels, the level of truck and rail capacity in the transportation market, a contracting driver market, severe weather conditions and specific customer demand.

Our operating revenue increased ~~$1.9 million,~~$642,000, or ~~1.2%~~0.4%, in the first three months of ~~2015.~~2016, despite a 51.1% decrease in fuel surcharge revenue to $10.0 million from $20.6 million in the first three months of 2015 due to lower fuel prices. Our operating revenue, net of both fuel surcharges and revenue from our dry container service discontinued in March 2015, increased ~~$13.2~~$12.5 million, or ~~10.3%~~8.9%, compared with the first three months of ~~2014.~~2015. Truckload segment revenue, net of fuel surcharges, ~~was $86.8 million~~decreased 4.5% from the first three months of 2015 primarily due to a decrease in ~~each of the 2015 and 2014 periods.~~our average revenue per tractor, partially offset by an increase in our average fleet size. Dedicated segment revenue, net of fuel surcharges, increased ~~85.2%~~78.8% primarily due to an increase in our average fleet size of ~~85.5%~~80.2% from the first three months of ~~2014.~~2015. Intermodal segment revenue, net of both fuel surcharges ~~decreased 7.3% due to the disposal of the overhead-intensive containers that were used in~~and revenue from our ~~intermodal operations, partially offset by~~discontinued dry container service, increased ~~volume with our temperature-controlled trailer service. Brokerage revenue increased 46.2% in~~1.0% from the first three months of 2015 due to an increase in ~~volume. Fuel surcharge~~volume in our temperature-controlled trailer service. Brokerage segment revenue ~~decreased to $20.6 million~~increased 3.2% in the first three months of ~~2015 from $31.9 million in the first three months of 2014, which was primarily~~2016 due to ~~lower fuel prices.~~

Our profitability is impacted by the variable costs of transporting freight for our customers, fixed costs, and expenses containing both fixed and variable components. The variable costs include fuel expense, driver-related expenses, such as wages, benefits, training, and recruitment, and independent contractor costs, which are recorded under purchased transportation. Expenses that have both fixed and variable components include maintenance and tire expense and our cost of insurance and claims. These expenses generally vary with the miles we travel, but also have a controllable component based on safety, fleet age, efficiency and other factors. Our main fixed costs relate to the acquisition and subsequent depreciation of long-term assets, such as revenue equipment and operating terminals. We expect our annual cost of tractor and trailer ownership will increase in future periods as a result of higher prices of new ~~equipment.~~equipment, along with any increases in fleet size. Although certain factors affecting our expenses are beyond our control, we monitor them closely and attempt to anticipate changes in these factors in managing our business. For example, fuel prices have significantly fluctuated over the past several years. We manage our exposure to changes in fuel prices primarily through fuel surcharge programs with our customers, as well as through volume fuel purchasing arrangements with national fuel centers and bulk purchases of fuel at our terminals. To help further reduce fuel expense, we have installed and tightly manage the use of auxiliary power units in our tractors to provide climate control and electrical power for our drivers without idling the tractor engine, and also have improved the fuel usage in the temperature-control units on our trailers. For our Intermodal and Brokerage segments, our profitability is impacted by the percentage of revenue we pay to providers for the transportation services we arrange, which is included within purchased transportation in our consolidated condensed statements of operations.

Our operating expenses as a percentage of operating revenue, or “operating ratio,” ~~improved~~increased to 91.3% in the first three months of 2016 from 89.3% in the first three months of ~~2015 from 94.6% in the first three months of 2014.~~2015. Operating expenses as a percentage of operating revenue, with both amounts net of fuel surcharges, ~~improved to 87.7%~~was 90.7% in the first three months of ~~2015 from 93.2% in the first three months of 2014.~~2016. Our operating ratio for the first three months of 2015, net of ~~a gain on the disposition of a facility of $3.7 million, improved to 91.6% and, net of~~ both ~~fuel surcharges and~~ the facility disposition gain ~~improved to~~of $3.7 million and fuel surcharges, was 90.3%. Our net income ~~increased by 92.7%~~decreased to $8.2 million, or $0.25 per diluted share, in the first three months of 2016 from $10.2 million, or $0.30 per diluted share, in the first three months of ~~2015 from $5.3~~2015. Net income improved 2.4% over earnings of $8.0 million, or ~~$0.16~~$0.24 per diluted share, in the first three months of ~~2014. The increase in profitability in the first three months of~~ 2015 ~~was primarily driven by the $0.06 per diluted share impact of~~excluding the facility disposition gain, ~~the increase~~due to increased operating income in our average Truckload revenue per tractor, the disposal of the overhead-intensive containers that were used in a portion of our intermodal operations, an improvement in net fuel expense with the lower fuel prices,Dedicated, Intermodal and ~~the impact that the severe weather conditions had on the first quarter of 2014 on both freight volumes and operating costs,~~Brokerage segments, partially offset by ~~an increase~~decreased operating income in ~~insurance and claims.~~our Truckload segment.

Our business requires substantial, ongoing capital investments, particularly for new tractors and trailers. At March 31, ~~2015,~~2016, we had ~~$21.7~~$1.2 million of cash and cash equivalents, ~~$398.7~~$410.8 million in stockholders’ equity and no long-term debt outstanding. In the first three months of ~~2015,~~2016, net cash flows provided by operating activities of ~~$53.2~~$55.1 million were primarily used to repay $37.9 million of long-term debt, to purchase new revenue equipment, net of proceeds from dispositions, in the amount of ~~$7.1~~$8.3 million, ~~to repay $24.4 million of long-term debt,~~ and to ~~increase cash~~repurchase and ~~cash equivalents by $21.6~~retire 455,581 shares of our common stock for $7.5 million. We estimate that capital expenditures, net of proceeds from dispositions, will be approximately ~~$95~~$120 million for the remainder ~~of 2015.~~2016. We believe our sources of liquidity are adequate to meet our current and anticipated needs for at least the next twelve months. Based upon anticipated cash flows, existing cash and cash equivalents balances, current borrowing availability and other sources of financing we expect to be available to us, we do not anticipate any significant liquidity constraints in the foreseeable future.

~~We have transformed our~~Our business strategy toencompasses a multifaceted set of transportation service solutions, primarily regional Truckload temperature-controlled operations along with Dedicated, Intermodal and Brokerage services, ~~while developing~~with a diverse customer base that gains value from and expands each of these operating segments. We believe that we are well-positioned regardless of the economic environment with ~~this transformation of our~~the services we provide combined with our competitive position, cost control emphasis, modern fleet and strong balance sheet.

This Management’s Discussion and Analysis of Financial Condition and Results of Operations includes discussions of operating revenue, net of fuel surcharge revenue; Truckload, Dedicated and Intermodal revenue, net of fuel surcharge revenue; operating revenue and Intermodal revenue, each net of fuel surcharge revenue and revenue from our dry container service discontinued in March 2015; operating expenses as a percentage of operating revenue, each net of fuel surcharge revenue ~~the facility disposition gain,~~ and the sum of ~~both amounts;~~fuel surcharge revenue and the facility disposition gain; and net fuel expense (fuel and fuel taxes net of fuel surcharge revenue and surcharges passed through to independent contractors, outside drayage carriers and railroads). We provide these additional disclosures because management believes these measures provide a more consistent basis for comparing results of operations from period to period. These financial measures in this report have not been determined in accordance with U.S. generally accepted accounting principles (GAAP). Pursuant to Item 10(e) of Regulation S-K, we have included the amounts necessary to reconcile these non-GAAP financial measures to the most directly comparable GAAP financial measures of operating revenue, operating expenses divided by operating revenue, and fuel and fuel taxes.

The increase in the operating ratio in the 2016 period was primarily due to a decrease in our average revenue per tractor within a soft freight market since the second quarter of 2015.

Dedicated segment revenue increased ~~$8.9~~$14.6 million, or ~~65.7%~~65.2%, to $37.1 million in the 2016 period from $22.5 million in the 2015 ~~period from $13.6 million in the 2014~~ period. Dedicated segment revenue, net of fuel surcharges, increased ~~85.2%~~78.8% primarily due to an increase in our average fleet size of ~~85.5%~~80.2% driven by a significant increase in ~~our~~the number of Dedicated contracts we have with customers. The ~~increase~~improvement in the operating ratio in the 2016 period, in spite of a decrease in the average revenue per tractor, was achieved by an improvement in insurance and claims expense along with other cost control measures.

Intermodal segment revenue decreased $3.2 million, or 15.6%, to $17.2 million in the 2016 period from $20.4 million in the 2015 period. Intermodal segment revenue, net of both fuel surcharges and $1.3 million of revenue from our discontinued dry container service, increased $155,000, or 1.0%, from the 2015 period due to an increase in volume in our temperature-controlled trailer service. The improvement in the operating ratio in the 2016 period was primarily due to the ~~addition of contracts with higher operating ratios than the average in the 2014 period.~~

Intermodal segment revenue decreased $3.3 million, or 13.9%, to $20.4 million in the 2015 period from $23.7 million in the 2014 period. Intermodal segment revenue, net of fuel surcharges, decreased 7.3% due to the disposal of the dry containers that were used in a portion of our intermodal operations, partially offset by increased volume with our temperature-controlled trailer service. The increase in profitability in the 2015 period was primarily due to the volume decrease in our dry container service, which produced a higher operating ratio than our temperature-controlled trailer service, ~~rate increases~~and a decrease in depreciation expense, as the ~~fourth quarter of 2014 and the first quarter of 2015, and the impact of severe weather conditions in the 2014 period on both freight volumes and operating costs.~~fleet size was reduced to optimize productivity.

Brokerage segment revenue increased ~~$5.4~~$537,000, or 3.2%, to $17.6 million ~~or 46.2%, to~~in the 2016 period from $17.0 million in the 2015 period, ~~from $11.7 million in the 2014 period, primarily~~ due to an increase in volume. The ~~increase~~improvement in the operating ratio ~~for our Brokerage segment~~ in the ~~2015~~2016 period was primarily due to ~~an increase~~a decrease in the payments to carriers for transportation services which we arranged as a percentage of our Brokerage revenue.

The following table sets forth for the periods indicated the dollar and percentage increase or decrease of the items in our unaudited consolidated condensed statements of operations, and those items as a percentage of operating revenue:

Salaries, wages and benefits consist of compensation for our employees, including both driver and non-driver employees, employees’ health insurance, 401(k) plan contributions and other fringe benefits. These expenses vary depending upon the size of our Truckload, Dedicated and Intermodal tractor fleets, the ratio of company drivers to independent contractors, our efficiency, our experience with employees’ health insurance claims, changes in health care premiums and other factors. The increase in salaries, wages and benefits from the ~~2014~~2015 period resulted primarily from a 7.0% increase in the total miles driven by company drivers and increases to several components of the amount paid to company ~~drivers and an increase in bonus compensation expense for our non-driver employees.~~drivers.

Purchased transportation consists of payments to railroads and carriers for transportation services we arrange in connection with Brokerage and Intermodal operations and to independent contractor providers of revenue equipment. This category will vary depending upon the amount and rates, including fuel surcharges, we pay to third-party railroad and motor carriers, the ratio of company drivers versus independent contractors and the amount of fuel surcharges passed through to independent contractors. Purchased transportation expense ~~increased $1.4~~decreased $1.5 million in total, or ~~4.9%~~5.0%, in the ~~2015~~2016 period from the ~~2014~~2015 period. Payments to carriers for transportation services we arranged in our Brokerage segment ~~increased $4.8 million to~~were $14.7 million in each of the 2016 and 2015 ~~period from $9.8 million in the 2014 period.~~periods. Payments to railroads and drayage carriers for transportation services within our Intermodal segment decreased ~~$3.7~~$1.9 million to $11.0 million in the 2016 period from $13.0 million in the 2015 ~~period from $16.7 million in the 2014~~ period. This decrease ~~is primarily~~was due to the ~~result~~disposal in March 2015 of the dry containers that were used in a portion of our intermodal operations, partially offset by increased volume ~~decrease in~~with our ~~dry container~~temperature-controlled intermodal trailer service. The portion of purchased transportation expense related to our independent contractors within our Truckload and Dedicated segments, including fuel surcharges, increased ~~$285,000~~$460,000 in the ~~2015~~2016 period. We expect that purchased transportation expense will increase as we grow our Intermodal and Brokerage segments.

Fuel and fuel taxes decreased by ~~$13.4~~$6.8 million in the ~~2015~~2016 period from the ~~2014~~2015 period. Net fuel expense (fuel and fuel taxes net of fuel surcharge revenue and surcharges passed through to independent contractors, outside drayage carriers and railroads) ~~decreased $4.0~~increased $2.3 million, or ~~32.3%~~27.4%, to $10.8 million in the 2016 period from $8.5 million in the 2015 ~~period from $12.5 million in the 2014~~ period. Fuel surcharges passed through to independent contractors, outside drayage carriers and railroads ~~were~~decreased to $1.2 million from $2.6 million in the 2015 ~~period and $4.6 million~~period. Despite a decrease in the ~~2014~~DOE national average cost of fuel to $2.07 per gallon from $2.92 per gallon in the 2015 period, net fuel expense increased to 8.1% of Truckload, Dedicated and Intermodal segment revenue, net of fuel surcharges, from 6.9% in the 2015 period. The net fuel expense to revenue was lower in the 2015 period due to our discount from retail being larger in this period due to the large decrease in fuel prices during the quarter, compared with level fuel prices in the 2016 period. The discount from retail typically increases when prices decrease and decreases when prices increase. We have worked diligently to control fuel usage and costs by improving our volume purchasing arrangements and optimizing our drivers’ fuel purchases with national fuel centers, focusing on shorter lengths of haul, installing and tightly managing the use of auxiliary power units in our tractors to minimize engine idling and improving fuel usage in the temperature-control units on our trailers. Auxiliary power units, which we have installed in our company-owned tractors, provide climate control and electrical power for our drivers without idling the tractor engine. The decrease in net fuel expense was primarily due to a decrease in the DOE national average cost of fuel to $2.92 per gallon in the 2015 period from $3.96 per gallon in the 2014 period and continued progress with the cost control measures stated above. Net fuel expense represented 6.9% of Truckload, Dedicated and Intermodal segment revenue, net of fuel surcharges, in the 2015 period, compared with 10.8% in the 2014 period.

Depreciation relates to owned tractors, trailers, auxiliary power units, communication units, terminal facilities and other assets. The increase in depreciation was primarily due to a continued increase in the cost of revenue ~~equipment.~~equipment and growth of our fleet. We expect our annual cost of tractor and trailer ownership will increase in future periods as a result of higher prices of new equipment, which will result in greater depreciation over the useful life.

Insurance and claims consist of the costs of insurance premiums and ~~the~~ accruals we make for claims within our self-insured retention amounts, primarily for personal injury, property damage, physical damage to our equipment, cargo claims and workers’ compensation claims. These expenses will vary primarily based upon the frequency and severity of our accident experience, our self-insured retention levels and the market for insurance. The ~~$2.0 million increase~~$735,000 decrease in insurance and claims in the ~~2015~~2016 period was primarily due to ~~an increase~~decreases in the cost of physical damage claims related to our tractors and trailers, self-insured auto liability ~~physical damage~~claims and workers’ compensation accident claims. Our significant self-insured retention exposes us to the possibility of significant fluctuations in claims expense between periods which could materially impact our financial results depending on the frequency, severity and timing of claims.

Gain on disposition of revenue equipment increased to $1.4 million in the 2016 period from $1.2 million in the 2015 ~~period from $663,000 in the 2014~~ period due to an increase in the ~~market value for used revenue equipment.~~number of tractors and trailers sold. Future gains or losses on dispositions of revenue equipment will be impacted by the market for used revenue equipment, which is beyond our control.

Gain on disposition of facility was $3.7 million in the 2015 period. The disposition of the facility, located in Ontario, CA, iswas part of our ongoing program to expand and update the footprint of our facilities throughout the United States, in which we have spent ~~over $75~~$84.3 million since ~~2008.~~2009. Any future gains or losses on disposition of facilities will be impacted by the market for real estate, which is beyond our control.

As a result of the foregoing factors, our operating expenses as a percentage of operating revenue, or “operating ratio,” ~~improved~~increased to 91.3% in the 2016 period from 89.3% in the 2015 ~~period from 94.6% in the 2014~~ period. The operating ratio for our Truckload segment was 92.3% in the 2016 period and 90.5% in the 2015 ~~period and 94.4% in the 2014~~ period, for our Dedicated segment was 88.3% in the 2016 period and 91.1% in the 2015 ~~period and 90.2% in the 2014~~ period, for our Intermodal segment was 88.8% in the 2016 period and 93.9% in the 2015 ~~period and 98.0% in the 2014~~ period, and for our Brokerage segment was 94.7% in the 2016 period and 95.6% in the 2015 ~~period and 94.4% in the 2014~~ period. Operating expenses as a percentage of operating revenue, with both amounts net of fuel surcharges, ~~improved to 87.7%~~was 90.7% in the ~~2015 period from 93.2% in the 2014~~2016 period.

As a result of the factors described above, net income ~~increased~~decreased to $8.2 million in the 2016 period from $10.2 million in the 2015 ~~period from $5.3 million in the 2014~~ period. Net earnings per diluted share ~~increased~~decreased to $0.25 in the 2016 period from $0.30 in the 2015 ~~period from $0.16~~period.

Our business requires substantial, ongoing capital investments, particularly for new tractors and trailers. Our primary sources of liquidity are funds provided by operations and our revolving credit facility. A portion of our tractor fleet is provided by independent contractors who own and operate their own equipment. We have no capital expenditure requirements relating to those drivers who own their tractors or obtain financing through third parties.

The table below reflects our net cash flows provided by operating activities, net cash flows used for investing activities and net cash flows used for financing activities for the periods indicated.

In the first three months of 2016, net cash flows provided by operating activities of $55.1 million were primarily used to repay $37.9 million of long-term debt, to purchase new revenue equipment, net of proceeds from dispositions, in the amount of $8.3 million, and to repurchase and retire 455,581 shares of our common stock for $7.5 million. In the first three months of 2015, net cash flows provided by operating activities of $53.2 million were primarily used to ~~purchase new revenue equipment, net of proceeds from dispositions, in the amount of $7.1 million, to~~ repay $24.4 million of long-term debt, ~~and~~ to increase cash and cash equivalents by $21.6 ~~million. In the first three months of 2014, net cash flows provided by operating activities of $27.5~~ million, ~~were primarily used~~and to purchase new revenue equipment, net of proceeds from dispositions, in the amount of ~~$17.7 million, to partially construct regional operating facilities in the amount of $1.5 million and to increase cash and cash equivalents by $5.7~~$7.1 million.

We estimate that capital expenditures, net of proceeds from dispositions, will be approximately ~~$95~~$120 million for the remainder of ~~2015. Quarterly~~2016.Quarterly cash dividends of $0.025 per share of common stock were declared in each of the first quarters of 2016 and 2015 totaling $811,000 and ~~2014 totaling~~ $837,000, ~~and $834,000,~~ respectively. We currently expect to continue to pay quarterly cash dividends in the future. The payment of cash dividends in the future, and the amount of any such dividends, will depend upon our financial condition, results of operations, cash requirements, and certain corporate law requirements, as well as other factors deemed relevant by our Board of Directors. As current federal and state bonus depreciation provisions have expired, we expect an increase in our current income tax payments as a portion of our deferred tax liability for property and equipment reverses. We believe our sources of liquidity are adequate to meet our current and anticipated needs for at least the next twelve months. Based upon anticipated cash flows, existing cash and cash equivalents balances, current borrowing availability and other sources of financing we expect to be available to us, we do not anticipate any significant liquidity constraints in the foreseeable future.

We maintain a credit agreement that provides for an unsecured committed credit facility which matures in December 2019. ~~The~~In November 2015, we entered into an amendment to the facility which increased the aggregate principal amount of the ~~credit~~ facility offrom $50.0 million ~~may be increased at our option, subject~~ to ~~completion of signed amendments with the lender, up to a maximum aggregate principal amount of~~ $75.0 million. At March 31, ~~2015,~~2016, there was no outstanding principal balance on the ~~credit~~ facility. As of that date, we had outstanding standby letters of credit of ~~$9.2~~$8.6 million and remaining borrowing availability of ~~$40.8~~$66.4 million. This facility bears interest at a variable rate based on the London Interbank Offered Rate or the lender’s Prime Rate, in each case plus/minus applicable margins.

Our credit facility prohibits us from paying, in any fiscal year, stock redemptions and dividends in excess of 25% of our net income from the prior fiscal year. A waiver of the 25% limitation for 2015 and 2016, should it apply, was obtained from the lender. This facility also contains restrictive covenants which, among other matters, require us to maintain compliance with cash flow leverage and fixed charge coverage ratios. We were in compliance with all ~~of these~~ covenants at March 31, ~~2015.~~2016.

The following is a summary of our contractual obligations as of March 31, ~~2015.~~2016.

Due to uncertainty with respect to the timing of future cash flows, the obligation under our nonqualified deferred compensation plan at March 31, ~~2015~~2016 of ~~70,590~~90,267 shares of Company common stock with a value of ~~$1.6~~$1.7 million has been excluded from the above table.

We own a 45% equity interest in MWL, a third-party provider of logistics services to the transportation industry. We received ~~$2.0 million~~$642,000 and ~~$1.7~~$2.0 million of our revenue for loads transported by our tractors and arranged by MWL in the three-month periods ended March 31, ~~2015~~2016 and March 31, ~~2014,~~2015, respectively. As of March 31, ~~2015,~~2016, we also had a trade receivable in the amount of ~~$880,000~~$268,000 from MWL and an accrued liability of ~~$2.9~~$4.0 million to MWL for the excess of payments by MWL’s customers into our lockbox account over the amounts drawn on the account by MWL.

We believe that the transactions with related parties noted above are on reasonable terms which, based upon market rates, are comparable to terms available from unaffiliated third parties.

Other than standby letters of credit maintained in connection with our self-insurance programs in the amount of ~~$9.2~~$8.6 million and operating leases summarized above in our summary of contractual obligations, we did not have any other material off-balance sheet arrangements at March 31, ~~2015.~~2016.

Most of our operating expenses are inflation-sensitive, with inflation generally producing increased costs of operations. During the last two years, the most significant effects of inflation have been on revenue equipment prices, accident claims, health insurance and employee compensation. We attempt to limit the effects of inflation through increases in freight rates and cost control efforts.

In addition to inflation, fluctuations in fuel prices can affect our profitability. We require substantial amounts of fuel to operate our tractors and power the temperature-control units on our trailers. Substantially all of our contracts with customers contain fuel surcharge provisions. Although we historically have been able to pass through a significant portion of long-term increases in fuel prices and related taxes to customers in the form of fuel surcharges and higher rates, such increases usually are not fully recovered. These fuel surcharge provisions are not effective in mitigating the fuel price increases related to non-revenue miles or fuel used while the tractor is idling.

Our tractor productivity generally decreases during the winter season because inclement weather impedes operations and some shippers reduce their shipments. At the same time, operating expenses generally increase, with harsh weather creating higher accident frequency, increased claims, lower fuel efficiency and more equipment repairs.

The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions about future events, and apply judgments that affect the reported amounts of assets, liabilities, revenue and expenses in our consolidated condensed financial statements and related notes. We base our estimates, assumptions and judgments on historical experience, current trends and other factors believed to be relevant at the time our consolidated condensed financial statements are prepared. However, because future events and their effects cannot be determined with certainty, actual results could differ from our estimates and assumptions, and such differences could be material. We believe that the following critical accounting policies affect our more significant estimates, assumptions and judgments used in the preparation of our consolidated condensed financial statements.

Revenue Recognition.We recognize revenue, including fuel surcharges,at the time shipment of freight is completed. We account for revenue of our Intermodal and Brokerage segments and revenue on freight transported by independent contractors within our Truckload and Dedicated segments on a gross basis because we are the primary obligor in the arrangements, we have the ability to establish prices, we have the risk of loss in the event of cargo claims and we bear credit risk with customer payments. Accordingly, all such revenue billed to customers is classified as operating revenue and all corresponding payments to carriers for transportation services we arrange in connection with brokerage and intermodal activities and to independent contractor providers of revenue equipment are classified as purchased transportation expense.

Accounts Receivable.We are dependent upon a limited number of customers, and, as a result, our trade accounts receivable are highly concentrated.Trade accounts receivable are recorded at the invoiced amounts, net of an allowance for doubtful accounts. Our allowance for doubtful accounts was ~~$462,000~~$305,000 as of March 31, ~~2015~~2016 and ~~$475,000 as of~~ December 31, ~~2014.~~2015. A considerable amount of judgment is required in assessing the realization of these receivables including the current creditworthiness of each customer and related aging of the past-due balances, including any billing disputes. In order to assess the collectibility of these receivables, we perform ongoing credit evaluations of our customers’ financial condition. Through these evaluations, we may become aware of a situation where a customer may not be able to meet its financial obligations due to deterioration of its financial viability, credit ratings or bankruptcy. The allowance for doubtful accounts is based on the best information available to us and is reevaluated and adjusted as additional information is received. We evaluate the allowance based on historical write-off experience, the size of the individual customer balances, past-due amounts and the overall national economy. We review the adequacy of our allowance for doubtful accounts monthly.

Property and Equipment. The transportation industry requires significant capital investments. Our net property and equipment was ~~$464.9~~$519.0 million as of March 31, ~~2015~~2016 and ~~$465.7~~$528.0 million as of December 31, ~~2014.~~2015. Our depreciation expense was $20.0 million for the first three months of 2016 and $17.8 million for the first three months of ~~2015 and $16.4 million for the first three months of 2014.~~2015. We compute depreciation of our property and equipment for financial reporting purposes based on the cost of each asset, reduced by its estimated salvage value, using the straight-line method over its estimated useful life. We determine and periodically evaluate our estimate of the projected salvage values and useful lives primarily by considering the market for used equipment, prior useful lives and changes in technology. We have not changed our policy regarding salvage values as a percentage of initial cost or useful lives of tractors and trailers within the last ten years. We believe that our policies and past estimates have been reasonable. Actual results could differ from these estimates. A 5% decrease in estimated salvage values would have decreased our net property and equipment as of March 31, ~~2015~~2016 by approximately ~~$10.3~~$10.9 million, or ~~2.2%~~2.1%.

Impairment of Assets.Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future net undiscounted cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less the costs to sell.

Insurance and Claims.We self-insure, in part, for losses relating to workers’ compensation, auto liability, general liability, cargo and property damage claims, along with employees’ health insurance with varying risk retention levels. We maintain insurance coverage for per-incident and total losses in excess of these risk retention levels in amounts we consider adequate based upon historical experience and our ongoing review. However, we could suffer a series of losses within our self-insured retention limits or losses over our policy limits, which could negatively affect our financial condition and operating results. We are responsible for the first $1.0 million on each auto liability claim and for the first $750,000 on each workers’ compensation claim. We have ~~$9.2~~$8.6 million in standby letters of credit to guarantee settlement of claims under agreements with our insurance carriers and regulatory authorities. The insurance and claims accruals in our consolidated condensed balance sheets were ~~$14.8~~$17.1 million as of March 31, ~~2015~~2016 and ~~$14.0~~$16.2 million as of December 31, ~~2014.~~2015. We reserve currently for the estimated cost of the uninsured portion of pending claims. We periodically evaluate and adjust these reserves based on our evaluation of the nature and severity of outstanding individual claims and our estimate of future claims development based on historical claims development factors. We believe that our claims development factors have historically been reasonable, as indicated by the adequacy of our insurance and claims accruals compared to settled claims.development. Actual results could differ from these current estimates. In addition, to the extent that claims are litigated and not settled, jury awards are difficult to predict. If our claims settlement experience worsened causing our historical claims development factors to increase by 5%, our estimated insurance and claims accruals as of March 31, 2015 would have needed to increase by approximately $3.8 million.

Share-based Payment Arrangement Compensation.We have granted stock options to certain employees and non-employee directors. We recognize compensation expense for all stock options net of an estimated forfeiture rate and only record compensation expense for those shares expected to vest on a straight-line basis over the requisite service period (normally the vesting period). Determining the appropriate fair value model and calculating the fair value of stock options require the input of highly subjective assumptions, including the expected life of the stock options and stock price volatility. We use the Black-Scholes model to value our stock option awards. We believe that future volatility will not materially differ from our historical volatility. Thus, we use the historical volatility of our common stock over the expected life of the award. The assumptions used in calculating the fair value of stock options represent our best estimates, but these estimates involve inherent uncertainties and the application of judgment. As a result, if factors change and we use different assumptions, stock option compensation expense could be materially different in the future.

We have also granted performance unit awards to certain employees which are subject to vesting requirements over a five-year period, primarily based on our earnings growth. The fair value of each performance unit is based on the closing market price on the date of grant. We recognize compensation expense for these awards based on the estimated number of units probable of achieving the performance and service vesting requirements of the awards, net of an estimated forfeiture rate.

In May 2014, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update No. 2014-09, “Revenue from Contracts with Customers” which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The standard, which is effective for the first quarter of ~~2017,~~2018, will replace most existing revenue recognition guidance required by U.S. generally accepted accounting principles. ~~Early application is not permitted.~~ The adoption of this standard is not expected to have a significant impact on our consolidated condensed balance sheets, statements of operations or statements of cash flows.

We are exposed to a variety of market risks, most importantly the effects of the price and availability of diesel fuel. We require substantial amounts of diesel fuel to operate our tractors and power the temperature-control units on our trailers. The price and availability of diesel fuel can vary, and are subject to political, economic and market factors that are beyond our control. Significant increases in diesel fuel costs could materially and adversely affect our results of operations and financial condition. Based upon our fuel consumption in the first three months of ~~2015,~~2016, a 5% increase in the average cost of diesel fuel would have increased our fuel expense by ~~$1.3 million.~~$952,000.

We have historically been able to pass through a significant portion of long-term increases in diesel fuel prices and related taxes to customers in the form of fuel surcharges. Fuel surcharge programs are widely accepted among our customers, though they can vary somewhat from customer-to-customer. These fuel surcharges, which adjust weekly with the cost of fuel, enable us to recover a substantial portion of the higher cost of fuel as prices increase. These fuel surcharge provisions are not effective in mitigating the fuel price increases related to non-revenue miles or fuel used while the tractor is idling. In addition, we have worked diligently to control fuel usage and costs by improving our volume purchasing arrangements and optimizing our drivers’ fuel purchases with national fuel centers, focusing on shorter lengths of haul, installing and tightly managing the use of auxiliary power units in our tractors to minimize engine idling and improving fuel usage in our trailers’ refrigeration units.

While we do not currently have any outstanding hedging instruments to mitigate this market risk, we may enter into derivatives or other financial instruments to hedge a portion of our fuel costs in the future.

As required by Rule 13a-15 under the Securities Exchange Act of 1934 (the “Exchange Act”), we have carried out an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Exchange Act Rule 13a-15(e)) as of the end of the period covered by this report. This evaluation was carried out under the supervision and with the participation of our management, including our Chief Executive Officer and our Executive Vice President and Chief Financial Officer. Based upon that evaluation, our Chief Executive Officer and our Executive Vice President and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of March 31, ~~2015.~~2016. There were no changes in our internal control over financial reporting that occurred during the period covered by this report that have materially affected, or that are reasonably likely to materially affect, our internal control over financial reporting. We intend to periodically evaluate our disclosure controls and procedures as required by the Exchange Act Rules.

We do not believe there are any material changes from the risk factors previously disclosed in Item1A to Part 1 of our Form 10-K for the year ended December 31, ~~2014.~~2015.

The following table shows our share repurchase activity during the first quarter of 2016:

In the fourth quarter of 2015, we repurchased and retired 941,024 shares of our common stock for $16.2 million. We repurchased and retired 455,581 shares of our common stock for $7.5 million in the first quarter of 2016.

Pursuant to the requirements of the Securities Exchange Act of 1934, the Registrant has duly caused this Report to be signed on its behalf by the undersigned, thereunto duly authorized.
