NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS

THREE MONTHS ENDED MARCH 31, 2012

(Unaudited)

(1) Basis of Presentation

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 financial statements should be read with reference to the consolidated financial statements and notes to consolidated financial statements in our 2011 Annual Report on Form 10-K.

The accompanying unaudited consolidated condensed financial statements include the accounts of Marten Transport, Ltd., its subsidiaries and its 45% owned affiliate, MW Logistics, LLC (MWL). MWL is a third-party provider of logistics services to the transportation industry. We have applied the provisions of Financial Accounting Standards Board Accounting Standards Codification, or FASB ASC, 810, Consolidation to our investment in MWL and have determined that Marten is the primary beneficiary based on MWL’s equity structure. All material intercompany accounts and transactions have been eliminated in consolidation. As of March 31, 2012, MWL’s total assets and total liabilities, net of intercompany accounts and transactions, were $5.8 million and $3.4 million, respectively. MWL has elected to be classified as a partnership for federal income tax purposes. Consequently, federal income taxes are not payable by MWL.

(2) Earnings Per Common Share

Basic and diluted earnings per common share were computed as follows:

	Three Months Ended March 31,
(In thousands, except per share amounts)	2012		2011
Numerator:
Net income	$	5,446	$	4,095
Denominator:
Basic earnings per common share - weighted-average shares		22,033		21,964
Effect of dilutive stock options		108		107
Diluted earnings per common share - weighted-average shares and assumed conversions		22,141		22,071

Basic earnings per common share	$	0.25	$	0.19
Diluted earnings per common share	$	0.25	$	0.19

Options totaling 272,500 and 350,800 shares for the three-month periods ended March 31, 2012 and March 31, 2011, respectively, were outstanding but were not included in the calculation of diluted earnings per share because including the options in the denominator would be antidilutive, or decrease the number of weighted-average shares, due to their exercise prices exceeding the average market price of the common shares or due to inclusion of average unrecognized compensation expense in the calculation.

Unvested performance unit awards totaling 35,680 and 15,850 shares for the three-month periods ended March 31, 2012 and March 31, 2011, 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) Long-Term Debt

We maintain a credit agreement that provides for an unsecured committed credit facility which matures in May 2016. The aggregate principal amount of the credit facility of $50 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 million. At March 31, 2012, there was no outstanding principal balance on the credit facility. As of that date, we had outstanding standby letters of credit of $8.9 million and remaining borrowing availability of $41.1 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.

(4) Related Party Transactions

We purchase fuel and obtain tires and related services from Bauer Built, Inc., or BBI. Jerry M. Bauer, one of our directors, is the president and a stockholder of BBI. We paid BBI $288,000 in the first three months of 2012 and $250,000 in the first three months of 2011 for fuel and tire services. In addition, we paid $369,000 in the first three months of 2012 and $343,000 in the first three months of 2011 to tire manufacturers for tires that we purchased from the tire manufacturers but were provided by BBI. BBI received commissions from the tire manufacturers related to these purchases.

(5) Income Taxes

Our effective income tax rate was 41.9% for the first three months of 2012 and 45.1% for the first three months of 2011. This decrease was primarily due to the impact of our driver per diem program on our effective tax rate.

The federal statute of limitations remains open for 2008 and forward. We file tax returns in numerous state jurisdictions with varying statutes of limitations.

(6) Dividends

In August 2010, we announced that our Board of Directors approved a regular cash dividend program to our stockholders, subject to approval each quarter. A quarterly cash dividend of $0.02 per share of common stock was paid in March 2012.

(7) Accounting for Share-based Payment Arrangement Compensation

We account for share-based payment arrangements in accordance with FASB ASC 718, Compensation – Stock Compensation . During the first three months of 2012, 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 2012 and 2011 was $248,000 and $238,000, respectively. See Note 9 to our consolidated financial statements in our 2011 Annual Report on Form 10-K for a detailed description of stock-based awards under our 2005 Stock Incentive Plan and 1995 Stock Incentive Plan.

(8) Fair Value of Financial Instruments

The carrying amounts of accounts receivable and accounts payable approximate fair value because of the short maturity of thes e instruments.

(9) Commitments and Contingencies

We are committed to: (a) purchase $45.3 million of new revenue equipment in the remainder of 2012; and (b) building construction and acquisition expenditures of $5.4 million in the remainder of 2012; and (c) operating lease obligation expenditures totaling $1.3 million through 2016.

We are involved in legal actions that arise in the ordinary course of business. Although the outcomes of any such legal actions cannot be predicted, in the opinion of management, the resolution of any currently pending or threatened actions will not have a material adverse effect upon our long-term financial position or results of operations, but could be material to the results of any individual period.

(10) Business Segments

We have six operating segments that have been aggregated into two reporting segments (Truckload and Logistics) for financial reporting purposes. The primary source of our operating revenue is truckload revenue, which we generate by transporting freight for our customers and report within our Truckload segment. Generally, we are paid by the mile for our services. We also derive truckload revenue from fuel surcharges, loading and unloading activities, equipment detention and other ancillary services.

Our operating revenue also includes revenue reported within our Logistics segment, which consists of revenue from our internal brokerage and intermodal operations, and through our 45% interest in MWL, a third-party provider of logistics services to the transportation industry. Brokerage services involve arranging for another company to transport freight for our customers while we retain the billing, collection and customer management responsibilities. Intermodal services involve the transport of our trailers on railroad flatcars for a portion of a trip, with the balance of the trip 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.

	Three Months Ended March 31,
(Dollars in thousands)	2012		2011
Operating revenue:
Truckload revenue, net of fuel surcharge revenue	$	89,198	$	81,973
Truckload fuel surcharge revenue		25,253		22,088
Total Truckload revenue		114,451		104,061

Logistics revenue, net of intermodal fuel surcharge revenue(1)		33,436		30,518
Intermodal fuel surcharge revenue		3,587		3,277
Total Logistics revenue		37,023		33,795

Total operating revenue	$	151,474	$	137,856

Operating income:
Truckload	$	7,128	$	5,321
Logistics		2,391		2,288
Total operating income	$	9,519	$	7,609

(1)

Logistics revenue is net of $2.5 million and $2.2 million of inter-segment revenue in the three-month periods ended March 31, 2012 and March 31, 2011, respectively, for loads transported by our tractors and arranged by MWL that have been eliminated in consolidation.

Truckload segment depreciation expense was $13.6 million and $12.8 million, and Logistics segment depreciation expense was $891,000 and $725,000, in the first three months of 2012 and 2011, respectively.

(11) Use of Estimates

We must make estimates and assumptions to prepare the consolidated condensed financial statements in conformity with U.S. generally accepted accounting principles. These estimates and assumptions affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities in the consolidated condensed financial statements and the reported amount of revenue and expenses during the reporting period. These estimates are primarily related to insurance and claims accruals and depreciation. Ultimate results could differ from these estimates.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results 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, 2011. We do not assume, and specifically disclaim, any obligation to update any forward-looking statement contained in this report.

Overview

The primary source of our operating revenue is truckload revenue, which we generate by transporting long-haul and regional freight for our customers and report within our Truckload segment. Generally, we are paid by the mile for our services. We also derive truckload revenue from fuel surcharges, loading and unloading activities, equipment detention and other ancillary services. The main factors that affect our truckload 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 revenue, net of fuel surcharges, per tractor per week. We also analyze our average truckload revenue, net of fuel surcharges, per total mile, non-revenue miles percentage, the miles per tractor we generate, our accessorial revenue and our other sources of operating revenue.

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 and specific customer demand.

Our operating revenue increased $13.6 million, or 9.9%, in the first three months of 2012. Our operating revenue, net of fuel surcharges, increased $10.1 million, or 9.0%, compared with the first three months of 2011. Truckload segment revenue, net of fuel surcharges, increased 8.8% primarily due to an increase in our average truckload revenue, net of fuel surcharges, per tractor per week of 4.5%, along with an increase in our average fleet size of 61 tractors, or 2.9%, in the first three months of 2012. Fuel surcharge revenue increased by $3.5 million, or 13.7%, which was caused by significantly higher fuel prices in the first three months of 2012. The changes in our operating statistics are primarily the result of the continued growth of our regional temperature-controlled operations, which we have increased to 67.8% of our truckload fleet as of March 31, 2012 from 57.1% as of March 31, 2011. By focusing on shorter lengths of haul in certain defined areas, we are addressing customer trends toward regional distribution to lower their transportation expense, furthering our own objectives of reducing fuel consumption per load, and matching some of our drivers’ desires to stay closer to home. The concentration of a portion of our fleet in these markets is evident in a 2.8% reduction from the first three months of 2011 in average length of haul to 618 miles. Logistics segment revenue, net of intermodal fuel surcharges, increased 9.6% compared with the first three months of 2011. The increase in logistics revenue primarily resulted from volume growth in each of our internal brokerage and intermodal services. Logistics revenue represented 24.4% of our operating revenue in the first three months of 2012 compared to 24.5% in the first three months of 2011.

Our profitability on the expense side is impacted by 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 total 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 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. 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 fluctuated dramatically over the past several years, with the United States Department of Energy, or DOE, national average cost of fuel increasing to $3.96 per gallon in the first three months of 2012 from $3.61 per gallon in the first three months of 2011. 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 installed auxiliary power units in our tractors to provide climate control and electrical power for our drivers without idling the tractor engine. For our Logistics segment, our profitability on the expense side is impacted by the percentage of logistics revenue we pay to providers for the transportation services we arrange.

Our operating expenses as a percentage of operating revenue, or “operating ratio,” improved to 93.7% in the first three months of 2012 from 94.5% in the first three months of 2011. Operating expenses as a percentage of operating revenue, with both amounts net of fuel surcharge revenue, improved to 92.2% for the first three months of 2012 from 93.2% for the first three months of 2011. Our net income increased to $5.4 million in the first three months of 2012 from $4.1 million in the first three months of 2011. The increased profitability in 2012 was primarily due to the increase in revenue per tractor per week in our Truckload segment.

Our business requires substantial, ongoing capital investments, particularly for new tractors and trailers. At March 31, 2012, we had approximately $25.6 million of cash and cash equivalents, $326.5 million in stockholders’ equity and no long-term debt outstanding. In the first three months of 2012, net cash flows provided by operating activities were primarily used to purchase new revenue equipment, net of proceeds from dispositions, in the amount of $11.2 million, to partially construct and acquire regional operating facilities in the amount of $4.0 million, and to increase cash and cash equivalents by $4.8 million. We estimate that capital expenditures, net of proceeds from dispositions, will be approximately $60 million for the remainder of 2012. We paid a quarterly cash dividend of $0.02 per share of common stock in March 2012 in the amount of $441,000. 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 been transforming our business strategy to a multifaceted set of transportation service solutions, primarily regional temperature-controlled operations along with intermodal and brokerage services, while developing a diverse customer base that gains value from and expands each of these operating units. We believe that we are well-positioned regardless of the economic environment with this transformation of our services 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, truckload and logistics revenue, and operating expenses as a percentage of operating revenue, each net of fuel surcharge revenue, 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, operating revenue, operating expenses divided by operating revenue, and fuel and fuel taxes.

Truckload segment depreciation expense was $13.6 million and $12.8 million, and Logistics segment depreciation expense was $891,000 and $725,000, in the 2012 and 2011 periods, respectively.

Our operating revenue increased $13.6 million, or 9.9%, to $151.5 million in the 2012 period from $137.9 million in the 2011 period. Our operating revenue, net of fuel surcharges, increased $10.1 million, or 9.0%, to $122.6 million in the 2012 period from $112.5 million in the 2011 period. The increase in operating revenue, net of fuel surcharges, was due to an increase in truckload revenue, net of fuel surcharges, along with growth in logistics revenue. Fuel surcharge revenue increased to $28.8 million in the 2012 period from $25.4 million in the 2011 period, which was caused by significantly higher fuel prices in 2012.

Truckload segment revenue increased $10.4 million, or 10.0%, to $114.5 million in the 2012 period from $104.1 million in the 2011 period. Truckload segment revenue, net of fuel surcharges, increased 8.8% primarily due to an increase in our average truckload revenue, net of fuel surcharges, per tractor per week of 4.5%, along with an increase in our average fleet size of 61 tractors, or 2.9%, in the 2012 period from the 2011 period. The changes in our operating statistics are primarily the result of the continued growth of our regional temperature-controlled operations, which we have increased to 67.8% of our truckload fleet as of March 31, 2012 from 57.1% as of March 31, 2011. By focusing on shorter lengths of haul in certain defined areas, we are addressing customer trends toward regional distribution to lower their transportation expense, furthering our own objectives of reducing fuel consumption per load, and matching some of our drivers’ desires to stay closer to home. The concentration of a portion of our fleet in these markets is evident in a 2.8% reduction from the 2011 period in average length of haul to 618 miles. The improvement in revenue per tractor per week was the primary cause of the increase in profitability from the 2011 period.

Logistics segment revenue increased $3.2 million, or 9.6%, to $37.0 million in the 2012 period from $33.8 million in the 2011 period. Logistics segment revenue, net of intermodal fuel surcharges, increased 9.6%. The increase in logistics revenue primarily resulted from continued volume growth in each of our internal brokerage and intermodal services. The operating ratio for our Logistics segment in the 2012 period was consistent with the 2011 period.

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 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 resulted primarily from a 5.4% increase in the total miles driven by company drivers, an increase in the amount paid to company drivers as a result of a pay increase effective April 1, 2011, and an additional $519,000 of detention pay due to a change in our policy to compensate company drivers when they are detained at pick up or delivery.

Purchased transportation consists of payments to independent contractor providers of revenue equipment and to carriers for transportation services we arrange in connection with brokerage and intermodal activities. This category will vary depending upon the ratio of company drivers versus independent contractors, the amount of fuel surcharges passed through to independent contractors and the amount and rates, including fuel surcharges, we pay to third-party railroad and motor carriers. Purchased transportation expense increased $1.8 million in total, or 6.6%, in the 2012 period from the 2011 period. Payments to carriers for transportation services we arranged in our brokerage and intermodal operations increased $2.8 million to $28.0 million in the 2012 period from $25.2 million in the 2011 period. The portion of purchased transportation expense related to our independent contractors, including fuel surcharges, decreased $991,000 in the 2012 period, primarily due to a decrease in the number of independent contractor-owned tractors in our fleet. We expect that purchased transportation expense will increase as we continue to grow our Logistics segment.

Fuel and fuel taxes increased by $3.8 million in the 2012 period from the 2011 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) increased $480,000, or 3.8%, to $13.2 million in the 2012 period from $12.7 million in the 2011 period. Fuel surcharges passed through to independent contractors, outside drayage carriers and railroads were $2.9 million in the 2012 period and $2.7 million in the 2011 period. 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 increase in net fuel expense was primarily due to a significant increase in the DOE national average cost of fuel to $3.96 per gallon in the 2012 period from $3.61 per gallon in the 2011 period. The cost control measures stated above helped to offset the higher price of fuel. Net fuel expense represented 13.1% of truckload and intermodal revenue, net of fuel surcharges, in the 2012 period, compared with 13.7% in the 2011 period.

Supplies and maintenance consist of repairs, maintenance, tires, parts, oil, and engine fluids, along with load-specific expenses including loading/unloading, tolls, pallets and trailer hostling. Our supplies and maintenance expense decreased 1.3% from the 2011 period despite our average fleet size increasing 2.9%. We experienced higher tire and toll costs in the 2012 period; however, these increased costs were more than offset by lower repair costs at both internal and external facilities.

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 2.9% increase in our average fleet size, a continued increase in the cost of revenue equipment and an increase in the relative percentage of company-owned tractors to independent contractor-owned tractors in the 2012 period. 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 $1.5 million increase in insurance and claims in the 2012 period was primarily due to a $978,000 increase in the cost of physical damage claims related to our tractors and trailers. Additionally, our self-insured auto liability claims increased $553,000 over the 2011 period. Our significant self-insured retention exposes us to the possibility of significant fluctuations in claims expense between periods depending on the frequency, severity and timing of claims and to adverse financial results if we incur large or numerous losses.

Gain on disposition of revenue equipment increased to $1.5 million in the 2012 period from $768,000 in the 2011 period primarily due to an increase in the number of tractors and trailers sold. Future gains or losses on disposition of revenue equipment will be impacted by the market for used revenue equipment, 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 to 93.7% in the 2012 period from 94.5% in the 2011 period. The operating ratio for our Truckload segment was 93.8% and 94.9% in the 2012 and 2011 periods, respectively. The operating ratio for our Logistics segment was 93.5% and 93.2% in the 2012 and 2011 periods, respectively. Operating expenses as a percentage of operating revenue, with both amounts net of fuel surcharge revenue, improved to 92.2% for the 2012 period from 93.2% for the 2011 period.

Our effective income tax rate decreased to 41.9% for the 2012 period from 45.1% for the 2011 period. This decrease was primarily due to the impact of our driver per diem program on our effective tax rate.

As a result of the factors described above, net income increased to $5.4 million in the 2012 period from $4.1 million in the 2011 period. Net earnings increased to $0.25 per diluted share in the 2012 period from $0.19 per diluted share in the 2011 period.

Liquidity and Capital Resources

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 provided by (used for) financing activities for the periods indicated.

	Three Months Ended March 31,
(In thousands)	2012			2011

Net cash flows provided by operating activities	$	19,779		$	27,991
Net cash flows (used for) investing activities		(15,173	)		(4,867	)
Net cash flows provided by (used for) financing activities		211			(20,389	)

In the first three months of 2012, net cash flows provided by operating activities were primarily used to purchase new revenue equipment, net of proceeds from dispositions, in the amount of $11.2 million, to partially construct and acquire regional operating facilities in the amount of $4.0 million, and to increase cash and cash equivalents by $4.8 million. We estimate that capital expenditures, net of proceeds from dispositions, will be approximately $60 million in the remainder of 2012. We paid a quarterly cash dividend of $0.02 per share of common stock in March 2012 in the amount of $441,000. 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 expire, 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.

Our credit facility prohibits us from paying, in any fiscal year, dividends in excess of 25% of our net income from the prior fiscal year. This facility also contains restrictive covenants which, among other matters, require us to maintain compliance with certain cash flow leverage and fixed charge coverage ratios. We were in compliance with all of these covenants at March 31, 2012.

The following is a summary of our contractual obligations as of March 31, 2012.

	Payments Due by Period
	Remainder		2013		2015
	of		And		And
(In thousands)	2012		2014		2016		Thereafter		Total

Purchase obligations for revenue equipment	$	45,268	$	—	$	—	$	—	$	45,268
Building construction obligations		5,433		—		—		—		5,433

Total	$	51,102	$	674	$	191	$	—	$	51,967

Due to uncertainty with respect to the timing of future cash flows, the obligation under our nonqualified deferred compensation plan at March 31, 2012 of 22,462.7 shares of Company common stock with a value of $496,000 has been excluded from the above table.

Related Parties

We paid Durand Builders Service, Inc. $118,000 in the first three months of 2012 and $184,000 in the first three months of 2011 for various construction projects. Larry B. Hagness, one of our directors, is the president and owner of Durand Builders Service, Inc. Other than any benefit received from his ownership interest, Mr. Hagness receives no compensation or other benefits from these transactions.

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.

Off-balance Sheet Arrangements

Other than standby letters of credit maintained in connection with our self-insurance programs in the amount of $8.9 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, 2012.

We have an investment in MWL which is considered to be a variable interest entity. As described in Note 1 to our consolidated condensed financial statements, we are considered to be the primary beneficiary and have consolidated MWL in our financial statements in accordance with the provisions of Financial Accounting Standards Board Accounting Standards Codification 810, Consolidation.

Inflation and Fuel Costs

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 surcharges and higher rates, such increases usually are not fully recovered. These surcharge provisions are not effective in mitigating the fuel price increases related to non-revenue miles or fuel used while the tractor is idling.

Seasonality

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 and more equipment repairs.

Critical Accounting Policies

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 Logistics segment and revenue on freight transported by independent contractors within our Truckload segment 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 $463,000 as of March 31, 2012 and $470,000 as of December 31, 2011. 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 $384.3 million as of March 31, 2012 and $368.2 million as of December 31, 2011. Our depreciation expense was $14.5 million in the first three months of 2012 and $13.5 million in the first three months of 2011. 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, 2012 by approximately $8.2 million, or 2.1%.

In the first three months of 2012, we replaced most of our company-owned tractors within approximately 4.5 years and our trailers within approximately 5.5 years after purchase. Our useful lives for depreciating tractors is five years and trailers is seven years, with a 25% salvage value for tractors and a 35% salvage value for trailers. These salvage values are based upon the expected market values of the equipment after five years for tractors and seven years for trailers. Depreciation expense calculated in this manner approximates the continuing declining value of the revenue equipment, and continues at a consistent straight-line rate for units held beyond the normal replacement cycle. Calculating tractor depreciation expense with a five-year useful life and a 25% salvage value results in the same depreciation rate of 15% of cost per year and the same net book value of 32.5% of cost at the 4.5-year replacement date as using a 4.5-year useful life and 32.5% salvage value. As a result, there is no difference in recorded depreciation expense on a quarterly or annual basis with our five-year useful life and 25% salvage value compared with a 4.5-year useful life and 32.5% salvage value. Similarly, calculating trailer depreciation expense with a seven-year useful life and a 35% salvage value results in the same depreciation rate of 9.3% of cost per year and the same net book value of 48.9% of cost at the 5.5-year replacement date as using a 5.5-year useful life and 48.9% salvage value. As a result, there is no difference in recorded depreciation expense on a quarterly or annual basis with our seven-year useful life and 35% salvage value compared with a 5.5-year useful life and 48.9% salvage value.

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 $8.9 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 $14.0 million as of March 31, 2012, and $13.0 million as of December 31, 2011. 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. 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 outstanding loss reserves as of March 31, 2012 would have needed to increase by approximately $3.4 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 vesting requirements of the awards, net of an estimated forfeiture rate.

Item 3. Quantitative And Qualitative Disclosures About Market Risk.

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 2012, a 5% increase in the average cost of diesel fuel would have increased our fuel expense by $1.9 million.

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.

Item 4. Controls and Procedures.

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 Chief Financial Officer. Based upon that evaluation, our Chief Executive Officer and our Chief Financial Officer concluded that our disclosure controls and procedures were effective as of March 31, 2012. 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.
