−Removed: While we attempt to identify, manage, and mitigate risks and uncertainties associated with our business, some level of risk and uncertainty will always be present. Our Form 10-K for the year ended December 31, 2020, as amended, and our Form 10-Q for the quarter ended June 30, 2021, in the section entitled "Item 1A.
−Removed: Risk Factors," describe some of the risks and uncertainties associated with our business.
−Removed: The information presented below supplements such risk factors.
−Removed: We are amending and restating in its entirety the risk factor entitled “Increased prices for new revenue equipment, design changes of new engines, future uses of autonomous tractors, volatility in the used equipment market, decreased availability of new revenue equipment, and the failure of manufacturers to meet their sale or trade-back obligations to us could have a materially adverse effect on our business, financial condition, results of operations, and profitability,”
−Removed: from our Annual Report Form 10-K for the year ended December 31, 2020, as amended, as set forth below.
−Removed: The risk factors set forth below should be read in conjunction with the risk factors included in our Annual Report on Form 10 K for the year ended December 31, 2020, as amended, and our Form 10-Q for the quarter ended June 30, 2021.
−Removed: These risks and uncertainties have the potential to materially affect our business, financial condition, results of operations, cash flows, projected results, and future prospects.
−Removed: The new rule concerning mandatory COVID-19 vaccination of employees could have a material adverse effect on our business, financial condition, and results of operations.
−Removed: On November 5, 2021, the Department of Labor's Occupational Safety and Health Administration ("OSHA") published an interim final rule (the "Emergency Rule") requiring all employers with at least 100 employees to ensure that their employees are fully vaccinated or require any employees who remain unvaccinated to produce a negative COVID-19 test result on at least a weekly basis before coming to work and wear a face covering while indoors or when occupying a vehicle with another person for work purposes.
−Removed: Employers will be required to comply with the Emergency Rule starting December 6, 2021, except for the provision requiring COVID-19 testing for employees who are not fully vaccinated, which will have a compliance date of January 4, 2022.
−Removed: We are still in the process of determining how the Emergency Rule will apply to our employees, including our professional truck drivers, as well as the impact on our team drivers and our interactions with customers and others at shipping facilities. When the Emergency Rule is implemented, it could, among other things, (i) cause our unvaccinated employees to go to smaller employers, not subject to the Emergency Rule, or leave us or the trucking industry, especially our unvaccinated drivers, (ii) result in logistical issues, increased expenses, and operational issues from arranging for weekly tests of our unvaccinated employees, especially our unvaccinated drivers, (iii) result in increased costs for recruiting and retention of drivers, as well as the cost of weekly testing, and (iv) result in decreased revenue if we are unable to recruit and retain new drivers due to the Emergency Rule.
−Removed: If the Emergency Rule is interpreted as applying to drivers, it would significantly reduce the pool of drivers available to us and our industry, which would further impact the extreme shortage of available drivers. 
−Removed: Furthermore, the actions by certain states may conflict with the Emergency Rule, causing further issues with compliance.
−Removed: Accordingly, the Emergency Rule, when implemented, could have a material adverse effect on our business, financial condition, and results of operations.
−Removed: Increased prices for new revenue equipment, design changes of new engines, future uses of autonomous tractors, volatility in the used equipment market, decreased availability of new revenue equipment, and the failure of manufacturers to meet their sale or trade-back obligations to us could have a materially adverse effect on our business, financial condition, results of operations, and profitability.
−Removed: We are subject to risk with respect to higher prices for new tractors.
−Removed: We have at times experienced an increase in prices for new tractors and the resale values of the tractors have not always increased to the same extent.
−Removed: Prices have increased and may continue to increase, due, in part, to (i) government regulations applicable to newly manufactured tractors and diesel engines, (ii) higher commodity prices, and (iii) the pricing discretion of equipment manufacturers.
−Removed: In addition, we have recently equipped our tractors with safety, aerodynamic, and other options that increase the price of new equipment.
−Removed: Compliance with such regulations has increased the cost of our new tractors, may increase the cost of new trailers, could impair equipment productivity, in some cases, result in lower fuel mileage, and increase our operating expenses.
−Removed: Our business could be harmed if we are unable to continue to obtain an adequate supply of new tractors and trailers for these or other reasons, and future use of autonomous tractors could increase the price of new tractors and decrease the value of used, non-autonomous tractors.
−Removed: As a result, we expect to continue to pay increased prices for equipment and incur additional expenses and related financing costs for the foreseeable future.
−Removed: Furthermore, reduced equipment efficiency may result from new engines designed to reduce emissions, thereby increasing our operating expenses.
−Removed: Currently, tractor and trailer manufacturers are experiencing significant shortages of semiconductor chips, steel, and other component parts and supplies, forcing many manufacturers to curtail or suspend their production, which has led to a lower supply of tractors and trailers, higher prices, and lengthened trade cycles, which could have a material adverse effect on our business, financial condition, and results of operations, particularly our maintenance expense and driver retention.
−Removed: A depressed market for used equipment could require us to trade our revenue equipment at depressed values or to record losses on disposal or impairments of the carrying values of our revenue equipment that is not protected by residual value arrangements.
−Removed: Used equipment prices are subject to substantial fluctuations based on freight demand, the supply of used tractors, the availability of financing, the presence of buyers for export to foreign countries, and commodity prices for scrap metal.
−Removed: If there is a deterioration of resale prices, it could have a material adverse effect on our business, financial condition, and results of operations.
−Removed: Certain of our revenue equipment financing arrangements have balloon payments at the end of the finance terms equal to the values we expect to be able to obtain in the used market.
−Removed: To the extent the used market values are lower than that, we may be forced to sell the equipment at a loss and our results of operations would be materially adversely affected.
+Added: While we attempt to identify, manage, and mitigate risks and uncertainties associated with our business, some level of risk and uncertainty will always be present. Our Form 10-K for the year ended December 31, 2021, in the section entitled "Item 1A.
+Added: Risk Factors," describes some of the risks and uncertainties associated with our business. These risks and uncertainties have the potential to materially affect our business, financial condition, results of operations, cash flows, projected results, and future prospects.
