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.</p>

  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;">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, along with dry freight, across the United States and into and out of Mexico and Canada. Our agreements with customers are typically for one year.</p>
  <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#xa0;</p>
  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;">Our Dedicated segment provides customized transportation solutions tailored to meet each individual customer&#x2019;s requirements, utilizing temperature-controlled trailers, dry vans and other specialized equipment within the United States. Our agreements with customers range from three to five years and are subject to annual rate reviews.</p>
  <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#xa0;</p>
  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;">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 accessorial 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.</p>
  <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#xa0;</p>
  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;">Our Intermodal segment transports our customers&#x2019; freight within the United States utilizing our temperature-controlled trailers and, beginning in September 2019, our refrigerated containers, each on railroad flatcars for portions of trips, with the balance of the trips using our tractors or, to a lesser extent, contracted carriers. The main factors that affect our Intermodal revenue are the rate per mile and other charges we receive from our customers.</p>
  <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#xa0;</p>
  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;">Our Brokerage segment develops contractual relationships with and arranges for 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 through Marten Transport Logistics, LLC, which was established in 2007 and operates pursuant to brokerage authority granted by the DOT. 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 that we receive from our customers.</p>
  <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#xa0;</p>
  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;">Operating results of our MRTN de Mexico business which offers our customers door-to-door service between the United States and Mexico with our Mexican partner carriers is reported within our Truckload and Brokerage segments.</p>
  <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#xa0;</p>
  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;">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.</p>

  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;">Our operating revenue increased $4.4 million, or 2.0%, in the first three months of 2021 from the first three months of 2020. Our operating revenue, net of fuel surcharges, increased $4.8 million, or 2.5%, compared with the first three months of 2020. Truckload segment revenue, net of fuel surcharges, increased 0.1% from the first three months of 2020 due to an increase in our average revenue per tractor, substantially offset by a reduction in our average number of tractors. Dedicated segment revenue, net of fuel surcharges, increased 4.3% from the first three months of 2020 primarily due to fleet growth driven by an increase in the number of Dedicated contracts we have with our customers. Intermodal segment revenue, net of fuel surcharges, decreased 5.6% primarily due to decreased load volume. Brokerage segment revenue increased 12.5% primarily due to an increase in revenue per load in the first three months of 2021. Fuel surcharge revenue decreased slightly to $24.9 million in the first three months of 2021 from $25.2 million in the first three months of 2020.</p>
  <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#xa0;</p>
  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;">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, 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 which is payable to the providers of the transportation services we arrange. This expense is included within purchased transportation in our consolidated condensed statements of operations.</p>
  <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#xa0;</p>
  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;">Our operating income improved 33.1% from $18.0 million in the first three months of 2020 to $24.0 million in the first three months of 2021, a period in which we overcame the impact of the severe winter weather in February 2021. Our operating expenses as a percentage of operating revenue, or &#x201c;operating ratio,&#x201d; improved to 89.2% in the first three months of 2021 from 91.8% in the first three months of 2020. Operating expenses as a percentage of operating revenue, with both amounts net of fuel surcharges, improved to 87.9% in the first three months of 2021 from 90.7% in the first three months of 2020. Our net income improved 31.3% to $18.0 million, or $0.22 per diluted share, in the first three months of 2021 from $13.7 million, or $0.17 per diluted share, in the first three months of 2020.</p>
  <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#xa0;</p>
  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;">Our business requires substantial, ongoing capital investments, particularly for new tractors and trailers. At March 31, 2021, we had $88.6 million of cash and cash equivalents, $635.0 million in stockholders&#x2019; equity and no long-term debt outstanding. In the first three months of 2021, net cash flows provided by operating activities of $43.6 million were primarily used to purchase new revenue equipment, net of proceeds from dispositions, in the amount of $16.3 million, to pay cash dividends of $3.3 million, and to upgrade regional operating facilities in the amount of $591,000, resulting in a $22.5 million increase in cash and cash equivalents. We estimate that capital expenditures, net of proceeds from dispositions, will be approximately $135 million for the remainder of 2021. 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.</p>
  <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#xa0;</p>
  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;">We continue to invest considerable time and capital resources to actively implement and promote long-term environmentally sustainable solutions that drive reductions in our fuel and electricity consumption and decrease our carbon footprint. These initiatives include (i) reducing idle time for our tractors by installing and tightly managing the use of auxiliary power units, which are powered by solar panels and provide climate control and electrical power for our drivers without idling the tractor engine, (ii) improving the energy efficiency of our newer, more aerodynamic and well-maintained tractor and trailer fleets by optimizing the equipment&#x2019;s specifications, weight and tractor speed, equipping our tractors with automatic transmissions, converting the refrigeration units in our refrigerated trailers to the new, more-efficient CARB refrigeration units along with increasing the insulation in the trailer walls and installing trailer skirts, and using ultra-fuel efficient and wide-based tires, and (iii) upgrading all of our facilities to indoor and outdoor LED lighting along with converting all of our facilities to solar power. Additionally, we are an active participant in the United States EPA SmartWay Transport Partnership, in which freight shippers, carriers, logistics companies and other voluntary stakeholders partner with the EPA to measure, benchmark and improve logistics operations to reduce their environmental footprint.</p>

Our continual redeployment of our drivers to match the changing freight demand by lane while minimizing empty miles has been and will continue to be imperative to the utilization of our revenue equipment and our operating revenue through this environment. Our execution of our unique multifaceted business model across our diverse customer base, including our ability to quickly make data-driven decisions and adjustments utilizing our in-house operating technology, has and will continue to be one of our key strengths as we proactively navigate through this fast-changing landscape in providing our essential service.</p>

  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;">Our operating revenue increased $4.4 million, or 2.0%, to $223.0 million in the 2021 period from $218.6 million in the 2020 period. Our operating revenue, net of fuel surcharges, increased $4.8 million, or 2.5%, to $198.2 million in the 2021 period from $193.4 million in the 2020 period. This increase was due to a $3.1 million increase in Brokerage revenue, a $2.7 million increase in Dedicated revenue, net of fuel surcharges, and a $62,000 increase in Truckload revenue, net of fuel surcharges, partially offset by a $1.1 million decrease in Intermodal revenue, net of fuel surcharges. Fuel surcharge revenue decreased slightly to $24.9 million in the 2021 period from $25.2 million in the 2020 period.</p>

Truckload segment revenue, net of fuel surcharges, increased $62,000, or 0.1%, and was $83.9 million in each of the 2021 and 2020 periods. During the 2021 period, an increase in our average revenue per tractor was substantially offset by a reduction in our average number of tractors. The improvement in the operating ratio in the 2021 period was primarily due to an increase in our average revenue per tractor due to increased rates with our customers.</p>

Dedicated segment revenue, net of fuel surcharges, increased 4.3% primarily due to fleet growth driven by an increase in the number of Dedicated contracts we have with our customers. The operating ratio was consistent in both the 2021 and 2020 periods.</p>

The improvement in the operating ratio in the 2021 period was primarily due to a decrease in the amounts payable to railroads as a percentage of our revenue.</p>

  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;">Salaries, wages and benefits consist of compensation for our employees, including both driver and non-driver employees, employees&#x2019; 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&#x2019; health insurance claims, changes in health care premiums and other factors. Salaries, wages and benefits expense increased $237,000, or 0.3%, in the 2021 period from the 2020 period. Bonus compensation expense for our non-driver employees increased by $1.1 million in the 2021 period. This increase, along with other smaller increases in the components of salaries, wages and benefits, were partially offset by a $1.4 million decrease in employees&#x2019; health insurance expense as a result of lower self-insured medical claims.</p>

  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;">Purchased transportation consists of amounts payable 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 $320,000 in total, or 0.8%, in the 2021 period from the 2020 period. Amounts payable to railroads and drayage carriers for transportation services within our Intermodal segment decreased $3.2 million to $12.6 million in the 2021 period from $15.8 million in the 2020 period, primarily due to a decrease in the volume of loads moved on the rail. Amounts payable to carriers for transportation services we arranged in our Brokerage segment increased $2.5 million to $23.6&#xa0;million in the 2021 period from $21.1 million in the 2020 period, primarily due to an increase in the cost per load within the tight freight market. The portion of purchased transportation expense related to independent contractors within our Truckload and Dedicated segments, including fuel surcharges, increased $1.1 million in the 2021 period as the number of independent contractors rose. We expect our purchased transportation expense to increase as we grow our Intermodal and Brokerage segments.</p>
  <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#xa0;</p>
  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;">Fuel and fuel taxes increased by $640,000, or 2.3%, in the 2021 period from the 2020 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 $332,000, or 5.3%, to $6.6 million in the 2021 period from $6.3 million in the 2020 period. Fuel surcharges passed through to independent contractors, outside drayage carriers and railroads decreased to $2.6 million from $3.2 million in the 2020 period. The United States Department of Energy, or DOE, national average cost of fuel increased slightly to $2.91 per gallon from $2.88 per gallon in the 2020 period. Net fuel expense increased to 3.9% of Truckload, Dedicated and Intermodal segment revenue, net of fuel surcharges, from 3.7% in the 2020 period. We have worked diligently to control fuel usage and costs by improving our volume purchasing arrangements and optimizing our drivers&#x2019; 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.</p>
  <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#xa0;</p>
  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;">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 $1.2 million, or 9.9%, from the 2020 period primarily due to lower parts, tires and outside repair costs.</p>
  <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#xa0;</p>
  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;">Insurance and claims consist of the costs of insurance premiums and 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&#x2019; 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 $838,000, or 6.8%, decrease in insurance and claims in the 2021 period was primarily due to a decrease in the cost of our self-insured auto liability claims, partially offset by increased insurance premiums. 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.</p>
  <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#xa0;</p>
  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;">Gain on disposition of revenue equipment was $2.0 million in the 2021 period, up from $1.6 million in the 2020 period primarily due to an increase in the 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.</p>
  <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#xa0;</p>
  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;">The $714,000 decrease in other operating expenses in the 2021 period was primarily due to decreased costs associated with travel and entertainment.</p>
  <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#xa0;</p>
  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;">Our operating income improved 33.1% to $24.0 million in the 2021 period from $18.0 million in the 2020 period as a result of the foregoing factors and by overcoming the impact of the severe winter weather in February 2021. Our operating expenses as a percentage of operating revenue, or &#x201c;operating ratio,&#x201d; improved to 89.2% in the 2021 period from 91.8% in the 2020 period. The operating ratio for our Truckload segment was 88.0% in the 2021 period and 92.9% in the 2020 period, for our Dedicated segment was 88.6% in each of the 2021 and 2020 periods, for our Intermodal segment was 93.4% in the 2021 period and 94.5% in the 2020 period, and for our Brokerage segment was 92.2% in the 2021 period and 94.3% in the 2020 period. Operating expenses as a percentage of operating revenue, with both amounts net of fuel surcharges, improved to 87.9% in the 2021 period from 90.7% in the 2020 period.</p>

  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;">In August 2019, our Board of Directors approved and we announced an increase from current availability in our existing share repurchase program providing for the repurchase of up to $34 million, or approximately 1.8 million shares, of our common stock, which was increased by our Board of Directors to 2.7 million shares in August 2020 to reflect the three-for-two stock split effected in the form of a stock dividend on August 13, 2020. The share repurchase program allows purchases on the open market or through private transactions in accordance with Rule 10b-18 of the Exchange Act. 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.</p>
  <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#xa0;</p>
  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;">We repurchased and retired 53,064 shares of common stock for $597,000 in the first quarter of 2020. We did not repurchase any shares in the rest of 2020 or in the first quarter of 2021. As of March 31, 2021, future repurchases of up to $33.4 million, or approximately 2.6 million shares, were available in the share repurchase program.</p>

  <p style="font-family: Times New Roman; font-size: 10pt; font-variant: normal; text-align: justify; margin: 0pt; text-indent: 36pt;">In the first three months of 2021, net cash flows provided by operating activities of $43.6 million were primarily used to purchase new revenue equipment, net of proceeds from dispositions, in the amount of $16.3 million, to pay cash dividends of $3.3 million, and to upgrade regional operating facilities in the amount of $591,000, resulting in a $22.5 million increase in cash and cash equivalents. In the first three months of 2020, net cash flows provided by operating activities of $43.5 million were primarily used to purchase new revenue equipment, net of proceeds from dispositions, in the amount of $34.6 million, to pay cash dividends of $2.2 million, and to upgrade regional operating facilities in the amount of $983,000, resulting in a $4.7 million increase in cash and cash equivalents. Beginning in 2018, our net cash flows have been increased by the new tax laws established by the Tax Cuts and Jobs Act of 2017, which reduces the federal corporate statutory income tax rate and establishes bonus depreciation that allows for full expensing of qualified assets.</p>
  <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#xa0;</p>
  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;">We estimate that capital expenditures, net of proceeds from dispositions, will be approximately $135 million for the remainder of 2021. A quarterly cash dividend of $0.04 per share of common stock was declared in the first quarter of 2021 which totaled $3.3 million. A quarterly cash dividend of $0.027 per share of common stock was declared in the first quarter of 2020 which totaled $2.2 million. 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. 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.</p>

At March 31, 2021, there was no outstanding principal balance on the facility. As of that date, we had outstanding standby letters of credit to guarantee settlement of self-insurance claims of $17.0 million and remaining borrowing availability of $13.0 million. This facility bears interest at a variable rate based on the London Interbank Offered Rate or the lender&#x2019;s Prime Rate, in each case plus/minus applicable margins.</p>

  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;">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 allowing stock redemptions and dividends in excess of the 25% limitation in a total amount of up to $60 million in 2020 was obtained from the lender in November 2020. 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 covenants at March 31, 2021 and December 31, 2020.</p>

  <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#xa0;</p>
  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;">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.</p>
  <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#xa0;</p>
  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;">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.</p>
  <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#xa0;</p>
  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;"><b>Seasonality</b></p>
  <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#xa0;</p>
  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;">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.</p>
  <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#xa0;</p>
  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;"><b>Critical Accounting Policies </b></p>
  <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#xa0;</p>
  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;">Our critical accounting policies are described in &#x201c;Management&#x2019;s Discussion and Analysis of Financial Condition and Results of Operations &#x2013; Critical Accounting Policies&#x201d; in our Annual Report on Form 10-K for the year ended December 31, 2020. We have reviewed and determined that those critical accounting policies remain our critical accounting policies as of and for the three months ended March 31, 2021, and that there have been no material changes to our critical accounting policies during this period.</p>

  <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#xa0;</p>
  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;">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 2021, a 5% increase in the average cost of diesel fuel would have increased our fuel expense by $1.4 million.</p>
  <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#xa0;</p>
  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;">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&#x2019; 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&#x2019; refrigeration units.</p>
  <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#xa0;</p>
  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;">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.</p>
  <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#xa0;</p>
  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;"><b>Item 4. Controls and Procedures.</b></p>
  <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#xa0;</p>
  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;">As required by Rule 13a-15 under the Securities Exchange Act of 1934 (the &#x201c;Exchange Act&#x201d;), 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, 2021. 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.</p>

   &lt;p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;"&gt;We maintain a credit agreement that provides for an unsecured committed credit facility with an aggregate principal amount of $30.0 million which matures in &lt;em style="font: inherit;"&gt; August 2023. &lt;/em&gt;At &lt;em style="font: inherit;"&gt; March 31, 2021, &lt;/em&gt;there was no outstanding principal balance on the facility. As of that date, we had outstanding standby letters of credit to guarantee settlement of self-insurance claims of $17.0 million and remaining borrowing availability of $13.0 million. At &lt;em style="font: inherit;"&gt; December 31, 2020, &lt;/em&gt;there was also no outstanding principal balance on the facility. As of that date, we also had outstanding standby letters of credit of $17.0 million on the facility. This facility bears interest at a variable rate based on the London Interbank Offered Rate or the lender&#x2019;s Prime Rate, in each case plus/minus applicable margins. The interest rate for the facility that would apply to outstanding principal balances was 0.78% at &lt;em style="font: inherit;"&gt; March 31, 2021.&lt;/em&gt;&lt;/p&gt;
   &lt;p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"&gt;&#160;&lt;/p&gt;
   &lt;p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;"&gt;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 allowing stock redemptions and dividends in excess of the &lt;em style="font: inherit;"&gt;25%&lt;/em&gt; limitation in a total amount of up to $60 million in &lt;em style="font: inherit;"&gt;2020&lt;/em&gt; was obtained from the lender in &lt;em style="font: inherit;"&gt; November 2020. &lt;/em&gt;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 covenants at &lt;em style="font: inherit;"&gt; March 31, 2021 &lt;/em&gt;and &lt;em style="font: inherit;"&gt; December 31, 2020.&lt;/em&gt;&lt;/p&gt;

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.&lt;/p&gt;

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.&lt;/p&gt;

   &lt;p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;"&gt;(&lt;em style="font: inherit;"&gt;12&lt;/em&gt;) Revenue and Business Segments&lt;/p&gt;
   &lt;p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"&gt;&#160;&lt;/p&gt;
   &lt;p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;"&gt;We account for our revenue in accordance with FASB ASC &lt;em style="font: inherit;"&gt;606,&lt;/em&gt; &lt;i&gt;Revenue from Contracts with Customers&lt;/i&gt;. We combine our five current operating segments into four reporting segments (Truckload, Dedicated, Intermodal and Brokerage) for financial reporting purposes. These &lt;em style="font: inherit;"&gt;four&lt;/em&gt; reporting segments are also the appropriate categories for the disaggregation of our revenue under FASB ASC &lt;em style="font: inherit;"&gt;606.&lt;/em&gt;&lt;/p&gt;
   &lt;p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"&gt;&#160;&lt;/p&gt;
   &lt;p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;"&gt;We have strategically transitioned from a refrigerated long-haul carrier to a multifaceted business offering a network of refrigerated and dry truck-based transportation capabilities across our &lt;em style="font: inherit;"&gt;five&lt;/em&gt; distinct business platforms &#x2013; Truckload, Dedicated, Intermodal, Brokerage and MRTN de Mexico.&lt;/p&gt;
   &lt;p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"&gt;&#160;&lt;/p&gt;
   &lt;p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;"&gt;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, along with dry freight, across the United States and into and out of Mexico and Canada. Our agreements with customers are typically for &lt;em style="font: inherit;"&gt;one&lt;/em&gt; year.&lt;/p&gt;
   &lt;p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"&gt;&#160;&lt;/p&gt;
   &lt;p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;"&gt;Our Dedicated segment provides customized transportation solutions tailored to meet individual customers&#x2019; requirements, utilizing temperature-controlled trailers, dry vans and other specialized equipment within the United States. Our agreements with customers range from &lt;span style="-sec-ix-hidden:c72445232"&gt;three&lt;/span&gt; to &lt;span style="-sec-ix-hidden:c72445233"&gt;five&lt;/span&gt; years and are subject to annual rate reviews.&lt;/p&gt;
   &lt;p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"&gt;&#160;&lt;/p&gt;
   &lt;p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;"&gt;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 accessorial 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.&lt;/p&gt;
   &lt;p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"&gt;&#160;&lt;/p&gt;


   &lt;p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;"&gt;Our Intermodal segment transports our customers&#x2019; freight within the United States utilizing our temperature-controlled trailers and, beginning in &lt;em style="font: inherit;"&gt; September 2019, &lt;/em&gt;our refrigerated containers, each on railroad flatcars for portions of trips, with the balance of the trips using our tractors or, to a lesser extent, contracted carriers. The main factors that affect our Intermodal revenue are the rate per mile and other charges we receive from our customers.&lt;/p&gt;
   &lt;p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"&gt;&#160;&lt;/p&gt;
   &lt;p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;"&gt;Our Brokerage segment develops contractual relationships with and arranges for &lt;em style="font: inherit;"&gt;third&lt;/em&gt;-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 through Marten Transport Logistics, LLC, which was established in &lt;em style="font: inherit;"&gt;2007&lt;/em&gt; and operates pursuant to brokerage authority granted by the United States Department of Transportation, or DOT. 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 that we receive from our customers.&lt;/p&gt;
   &lt;p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"&gt;&#160;&lt;/p&gt;
   &lt;p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;"&gt;Operating results of our MRTN de Mexico business which offers our customers door-to-door service between the United States and Mexico with our Mexican partner carriers is reported within our Truckload and Brokerage segments.&lt;/p&gt;
   &lt;p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;"&gt;&#160;&lt;/p&gt;
   &lt;p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;"&gt;Our customer agreements are typically for &lt;span style="-sec-ix-hidden:c72445237"&gt;one&lt;/span&gt;-year terms except for our Dedicated agreements which range from &lt;em style="font: inherit;"&gt;three&lt;/em&gt; to &lt;em style="font: inherit;"&gt;five&lt;/em&gt; years with annual rate reviews. Under FASB ASC &lt;em style="font: inherit;"&gt;606,&lt;/em&gt; the contract date for each individual load within each of our &lt;em style="font: inherit;"&gt;four&lt;/em&gt; reporting segments is generally the date that each load is tendered to and accepted by us. For each load transported within each of our &lt;em style="font: inherit;"&gt;four&lt;/em&gt; reporting segments, the entire amount of revenue to be recognized is a single performance obligation and our agreements with our customers detail the per-mile charges for line haul and fuel surcharges, along with the rates for loading and unloading, stop offs and drops, equipment detention and other accessorial services, which is the transaction price. There are &lt;em style="font: inherit;"&gt;no&lt;/em&gt; discounts that would be a material right or consideration payable to a customer. We are required to recognize revenue and related expenses over time, from load pickup to delivery, for each load within each of our &lt;em style="font: inherit;"&gt;four&lt;/em&gt; reporting segments. We base our calculation of the amount of revenue to record in each period for individual loads picking up in &lt;em style="font: inherit;"&gt;one&lt;/em&gt; period and delivering in the following period using the number of hours estimated to be incurred within each period applied to each estimated transaction price. Contract assets for this estimated revenue which are classified within prepaid expenses and other within our consolidated condensed balance sheets were $2.4 million and $1.5 million as of &lt;em style="font: inherit;"&gt; March 31, 2021 &lt;/em&gt;and &lt;em style="font: inherit;"&gt; December 31, 2020, &lt;/em&gt;respectively. We had no impairment losses on contract assets in the &lt;em style="font: inherit;"&gt;first&lt;/em&gt; quarter of &lt;em style="font: inherit;"&gt;2021&lt;/em&gt; or in &lt;em style="font: inherit;"&gt;2020.&lt;/em&gt; We bill our customers for loads after delivery is complete with standard payment terms of &lt;em style="font: inherit;"&gt;30&lt;/em&gt; days.&lt;/p&gt;
   &lt;p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"&gt;&#160;&lt;/p&gt;
   &lt;p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;"&gt;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 principal service provider controlling the promised service before it is transferred to each customer. We are primarily responsible for fulfilling the promise to provide each specified service to each customer. We bear the primary risk of loss in the event of cargo claims by our customers. We also have complete control and discretion in establishing the price for each specified service. 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 within our consolidated condensed statements of operations.&lt;/p&gt;
   &lt;p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"&gt;&#160;&lt;/p&gt;


   &lt;p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;"&gt;The following table sets forth for the periods indicated our operating revenue and operating income by segment. We do &lt;em style="font: inherit;"&gt;not&lt;/em&gt; prepare separate balance sheets by segment and, as a result, assets are &lt;em style="font: inherit;"&gt;not&lt;/em&gt; separately identifiable by segment.&lt;/p&gt;
   &lt;p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"&gt;&#160;&lt;/p&gt;

   &lt;p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;"&gt;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.&lt;/p&gt;

   <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#160;</p>
   <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;">We account for our revenue in accordance with FASB ASC <em style="font: inherit;">606,</em> <i>Revenue from Contracts with Customers</i>. We combine our five current operating segments into four reporting segments (Truckload, Dedicated, Intermodal and Brokerage) for financial reporting purposes. These <em style="font: inherit;">four</em> reporting segments are also the appropriate categories for the disaggregation of our revenue under FASB ASC <em style="font: inherit;">606.</em></p>
   <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#160;</p>
   <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;">We have strategically transitioned from a refrigerated long-haul carrier to a multifaceted business offering a network of refrigerated and dry truck-based transportation capabilities across our <em style="font: inherit;">five</em> distinct business platforms &#8211; Truckload, Dedicated, Intermodal, Brokerage and MRTN de Mexico.</p>
   <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#160;</p>
   <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;">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, along with dry freight, across the United States and into and out of Mexico and Canada. Our agreements with customers are typically for <em style="font: inherit;">one</em> year.</p>
   <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#160;</p>
   <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;">Our Dedicated segment provides customized transportation solutions tailored to meet individual customers&#8217; requirements, utilizing temperature-controlled trailers, dry vans and other specialized equipment within the United States. Our agreements with customers range from <span style="-sec-ix-hidden:c72445232">three</span> to <span style="-sec-ix-hidden:c72445233">five</span> years and are subject to annual rate reviews.</p>
   <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#160;</p>
   <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;">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 accessorial 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.</p>
   <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#160;</p>


   <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;">Our Intermodal segment transports our customers&#8217; freight within the United States utilizing our temperature-controlled trailers and, beginning in <em style="font: inherit;"> September 2019, </em>our refrigerated containers, each on railroad flatcars for portions of trips, with the balance of the trips using our tractors or, to a lesser extent, contracted carriers.

   <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;">Our Brokerage segment develops contractual relationships with and arranges for <em style="font: inherit;">third</em>-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 through Marten Transport Logistics, LLC, which was established in <em style="font: inherit;">2007</em> and operates pursuant to brokerage authority granted by the United States Department of Transportation, or DOT. 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 that we receive from our customers.</p>

   <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;">Our customer agreements are typically for <span style="-sec-ix-hidden:c72445237">one</span>-year terms except for our Dedicated agreements which range from <em style="font: inherit;">three</em> to <em style="font: inherit;">five</em> years with annual rate reviews. Under FASB ASC <em style="font: inherit;">606,</em> the contract date for each individual load within each of our <em style="font: inherit;">four</em> reporting segments is generally the date that each load is tendered to and accepted by us. For each load transported within each of our <em style="font: inherit;">four</em> reporting segments, the entire amount of revenue to be recognized is a single performance obligation and our agreements with our customers detail the per-mile charges for line haul and fuel surcharges, along with the rates for loading and unloading, stop offs and drops, equipment detention and other accessorial services, which is the transaction price. There are <em style="font: inherit;">no</em> discounts that would be a material right or consideration payable to a customer. We are required to recognize revenue and related expenses over time, from load pickup to delivery, for each load within each of our <em style="font: inherit;">four</em> reporting segments. We base our calculation of the amount of revenue to record in each period for individual loads picking up in <em style="font: inherit;">one</em> period and delivering in the following period using the number of hours estimated to be incurred within each period applied to each estimated transaction price. Contract assets for this estimated revenue which are classified within prepaid expenses and other within our consolidated condensed balance sheets were $2.4 million and $1.5 million as of <em style="font: inherit;"> March 31, 2021 </em>and <em style="font: inherit;"> December 31, 2020, </em>respectively. We had no impairment losses on contract assets in the <em style="font: inherit;">first</em> quarter of <em style="font: inherit;">2021</em> or in <em style="font: inherit;">2020.</em> We bill our customers for loads after delivery is complete with standard payment terms of <em style="font: inherit;">30</em> days.</p>
   <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#160;</p>
   <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;">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 principal service provider controlling the promised service before it is transferred to each customer. We are primarily responsible for fulfilling the promise to provide each specified service to each customer. We bear the primary risk of loss in the event of cargo claims by our customers. We also have complete control and discretion in establishing the price for each specified service. 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 within our consolidated condensed statements of operations.</p>

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.</p>
