The accompanying notes are an integral part of these consolidated financial statements.

The interim consolidated financial statements included herein have been prepared by Rush Enterprises, Inc. and its subsidiaries (collectively referred to as the “Company”), without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). All adjustments have been made to the accompanying interim consolidated financial statements, which, in the opinion of the Company’s management, are necessary for a fair presentation of its operating results. All adjustments are of a normal recurring nature. Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted pursuant to such rules and regulations. It is recommended that these interim consolidated financial statements be read in conjunction with the consolidated financial statements and the notes thereto included in the Company’s Annual Report on Form ~~10-K~~10-K for the year ended December 31, ~~2016.~~ 2020. Results of operations for interim periods are not necessarily indicative of results that may be expected for any other interim periods or the full fiscal year.

In March 2020, the World Health Organization made the assessment that COVID-19 could be characterized as a pandemic, and the President of the United States declared the COVID-19 outbreak a national emergency. The Company’s nationwide network of commercial vehicle dealerships are classified as “essential businesses” and have remained operational across the Company’s dealership network. While the COVID-19 pandemic is not over, business conditions have improved significantly since the second quarter of 2020. The Company is unable to predict the impact that the COVID-19 pandemic will have on its future business and operating results due to numerous uncertainties, including the duration and severity of the outbreak.

In March 2020, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update 2020-04,Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting ("ASU 2020-04"). In January 2021, the FASB issued Accounting Standards Update No.2021-01,Reference Rate Reform (Topic 848): Scope, which clarified the scope and application of the original guidance. The guidance in these standards applies to contract accounting, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met and provides optional expedients and exceptions for a limited time to ease the potential burden in accounting for reference rate reform. The amendments apply only to contracts and hedging relationships that reference LIBOR or another reference rate expected to be discontinued due to reference rate reform. ASU 2020-04 is effective upon issuance and generally can be applied to applicable contract modifications through December 31, 2022. LIBOR benchmarking is utilized in the Company’s working capital and floorplan facilities. The Company is in the process of completing its evaluation of the impact, if any, that the adoption of this standard will have on its Consolidated Financial Statements.

The total capitalized costs of the Company’s SAP enterprise software and SAP dealership management system of $30.5 million, including capitalized interest, are recorded on the Consolidated Balance Sheet in Other Assets, net of accumulated amortization of $19.1 million, at September 30, 2017. The SAP software is being amortized over a period of 15 years.

~~Amortization expense relating to the SAP~~ software, which is recognized in depreciation and amortization expense in the Consolidated Statement of Income and Comprehensive Income, was $0.9 million for the three months ended September 30, 2017 and $0.9 million for the three months ended September 30, 2016; it was $2.6 million for the nine months ended September 30, 2017 and $2.5 million for the nine months ended September 30, 2016. The Company currently estimates that amortization expense relating to the SAP software will be approximately $3.4 million for each of the next five years.Franchise Rights

The ~~Company~~’sCompany’s only significant identifiable intangible assets, other than goodwill, are rights under franchise agreements with manufacturers. The fair value of the franchise right is determined at the acquisition date by discounting the projected cash flows specific to each acquisition. The carrying value of the Company’s manufacturer franchise rights was $7.0 million ~~at both~~ as of September 30, ~~2017~~ 2021 and December 31, ~~2016,~~ 2020, and is included in Other Assets on the accompanying ~~consolidated balance sheets.~~Consolidated Balance Sheet. The Company has determined that manufacturer franchise rights have an indefinite life, as there are no economic or other factors that limit their useful lives and they are expected to generate cash flows indefinitely due to the historically long lives of the manufacturers’ brand names. Furthermore, to the extent that any agreements evidencing manufacturer franchise rights have expiration dates, the Company expects that it will be able to renew those agreements in the ordinary course of business. Accordingly, the Company does not amortize manufacturer franchise rights.

Due to the fact that manufacturer franchise rights are specific toa geographic region, the Company has determined that evaluating and including all locations acquired in the geographic region is the appropriate level for ~~the purpose~~purposes of testing franchise rights for impairment. Management reviews indefinite-lived manufacturer franchise rights for impairment annually during the fourth quarter, or more often if events or circumstances indicate that an impairment may have occurred. The Company is subject to financial statement risk to the extent that manufacturer franchise rights become impaired due to decreases in the fair market value of its individual ~~franchises within a particular region.~~franchises.

The significant estimates and assumptions used by management in assessing the recoverability of manufacturer franchise rights include estimated future cash flows, present value discount rate and other factors. Any changes in these estimates or assumptions could result in an impairment charge. The estimates of future cash flows, based on reasonable and supportable assumptions and projections, require management’s subjective judgment. Depending on the assumptions and estimates used, the estimated future cash flows projected in the evaluations of manufacturer franchise rights can vary within a range of outcomes.

NoNaN impairment ~~write down of manufacturer franchise rights~~write-down was required in ~~any~~the period presented. The Company cannot predict the occurrence of certain events that might adversely affect the reported value of manufacturer franchise rights in the future.

On February 25, 2019, the Company acquired 50% of the equity interest in Rush Truck Centres of Canada Limited (“RTC Canada”), which acquired the operating assets of Tallman Group, the largest International Truck dealer in Canada. The Company was also granted a call option in the purchase agreement that provides the Company with the right to acquire the remaining 50% equity interest in RTC Canada until the close of business on February 25, 2024. The value of the Company’s call option was $3.6 million as of September 30, 2021, and is reported in Other Assets on the Consolidated Balance Sheet.

On April 25, 2019, the Company entered into a Guaranty Agreement (“Guaranty”) with Bank of Montreal (“BMO”), pursuant to which the Company agreed to guaranty up to CAD250 million (the “Guaranty Cap”) of certain credit facilities entered into by and between Tallman Truck Centre Limited (“TTCL”) and BMO. The Company owned a 50% equity interest in TTCL, which was the sole owner of RTC Canada. Later in 2019, RTC Canada and TTCL were amalgamated into RTC Canada. Interest, fees and expenses incurred by BMO to enforce its rights with respect to the guaranteed obligations and its rights against the Company under the Guaranty are not subject to the Guaranty Cap. In exchange for the Guaranty, RTC Canada is receiving a reduced rate of interest on its credit facilities with BMO. The Guaranty was valued at $5.2 million as of September 30, 2021 and December 31, 2020, and is included in the investment in RTC Canada. As of September 30, 2021, the Company’s investment in RTC Canada is $35.1 million. The Company’s equity income in RTC Canada is included in Other income on the Consolidated Statements of Income.

The total capitalized costs of the Company’s SAP enterprise resource planning software platform (“the ERP Platform”) of $5.8 million are recorded on the Consolidated Balance Sheet in Other Assets. Amortization expense relating to the ERP Platform, which is recognized in depreciation and amortization expense in the Consolidated Statements of Income and Comprehensive Income, was $0.3 million for the three months ended September 30, 2021 and $0.5 million for the three months ended September 30, 2020, and $1.2 million for the nine months ended September 30, 2021 and $1.4 million for the nine months ended September 30, 2020. The Company estimates that amortization expense relating to the ERP Platform will be approximately $1.5 million in 2021 and $1.2 million per year for the next four years.

From time to time, the Company is involved in litigation arising out of its operations in the ordinary course of business. The Company maintains liability insurance, including product liability coverage, in amounts deemed adequate by management. To date, aggregate costs to usthe Company for claims, including product liability actions, have not been material. However, an uninsured or partially insured claim, or claim for which indemnification is not available, could have a material adverse effect on the ~~Company~~’sCompany’s financial condition or results of operations. The Company believes that there are no claims or litigation pending, the outcome of which could have a material adverse effect on its financial position or results of operations. However, due to the inherent uncertainty of litigation, there can be no assurance that the resolution of any particular claim or proceeding would not have a material adverse effect on the Company’s financial condition or results of operations for the fiscal period in which such resolution occurred.

The following table sets forth the computation of basic and diluted earnings per share (in thousands, except per share information):

Options to purchase shares of common stock that were outstanding for the three months and nine months ended September 30, ~~2017~~ 2021 and ~~2016~~2020 that were not included in the computation of diluted earnings per share because the effect would have been anti-dilutive are as follows (in thousands):

The Company accounts for stock-based compensation in accordance with ~~Accounting Standards Codification (“ASC”) 718-10, “Compensation~~ ASC 718-10,Compensation – Stock Compensation,” which requires the measurement and recognition of compensation expense for all share-based payment awards made to ~~our~~the Company’s employees and directors, including employee stock options, restricted stock unit awards, restricted stock awards and employee stock purchases related to the ~~Company’s employee stock purchase plan~~Employee Stock Purchase Plan based on estimated fair values. ~~The Company adopted~~ ~~Accounting Standards Update (“ASU”) No. 2016-09, “~~~~Compensation – Stock Compensation (Topic 718~~) ~~on January 1, 2017.~~ The Company recorded excess tax benefits of $1.9 million in the three months ended September 30, 2017 and $3.9 million in the nine months ended September 30, 2017, which was recorded in the Consolidated Statements of Income and Comprehensive Income.

Stock-based compensation expense, calculated using the Black-Scholes option-pricing model for employee stock options, and included in selling, general and administrative expense,, was ~~$3.4~~$3.1 million for the three months ended September 30, ~~2017,~~ 2021, and ~~$2.7~~$3.3 million for the three months ended September 30, ~~2016.~~ 2020. Stock-based compensation expense was $18.3 million for the nine months ended September 30, ~~2017, was $12.0~~2021, and $15.5 million ~~and~~ for the nine months ended September 30, ~~2016, was $9.4 million.~~ 2020.

As of September 30, ~~2017,~~ 2021, the Company had ~~$9.0~~$10.3 million of unrecognized compensation expense related to non-vested employee stock options to be recognized over a weighted-average period of ~~3.0~~2.3 years and ~~$7.6~~$11.0 million of unrecognized compensation cost related to non-vested restricted stock ~~units~~awards to be recognized over a weighted-average period of ~~1.7~~1.4 years.

The Company ~~has various~~ measures certain financial ~~instruments that it must measure~~assets and liabilities at fair value on a recurring basis. The Company also applies the provisions of fair value measurement to various nonrecurring measurements for its financial and nonfinancial assets and liabilities. Applicable accounting standards define fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (an exit price). The Company measures its assets and liabilities using inputs from the following three levels of the fair value hierarchy:

~~Level 1 inputs are unadjusted quoted prices in active markets for identical assets or liabilities that~~ ~~the Company has the ability to access at the measurement date.~~

Level 2 inputs include quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (i.e., interest rates, yield curves, etc.), and inputs that are derived principally from or corroborated by observable market data by correlation or other means (market corroborated inputs).

~~Level 3 includes unobservable inputs that reflect~~ the Company’s assumptions about what factors market participants would use in pricing the asset or liability. The Company develops these inputs based on the best information available, including its own data.

Financial instruments consist primarily of cash, accounts receivable, accounts payable and floor plan notes payable. The carrying values of the Company’s financial instruments approximate fair value due either to their short-term nature or existence of variable interest rates, which approximate market rates. Certain methods and assumptions were used by the Company in estimating the fair value of financial instruments at as of September 30, ~~2017,~~ 2021, and December 31, ~~2016.~~ 2020. The carrying value of current assets and current liabilities approximates the fair value due to the short maturity of these items.

The fair value of the Company’s long-term debt is based on secondary market indicators. Because the Company’s debt is not quoted, estimates are based on each obligation’s characteristics, including remaining maturities, interest ~~rate,~~rates, credit rating, collateral and liquidity. Accordingly, the Company concluded that the valuation measurement inputs of its long-term debt represent, at its lowest level, current market interest rates available to the Company for similar debt and ~~its~~the Company’s current credit ~~standing and has categorized such debt within Level 2 of the hierarchy framework.~~standing. The carrying amount of such debt approximates fair value.

If investments are deemed to be impaired, the Company determines whether the impairment is temporary or other than temporary. If the impairment is deemed to be temporary, the Company records an unrealized loss in other comprehensive income. If the impairment is deemed other than temporary, the Company records the impairment in the Company~~’s Consolidated Statements of Income and Comprehensive Income.~~

In prior years, the Company invested in interest-bearing short-term investments primarily consisting of investment-grade auction rate securities classified as available-for-sale and reported at fair value. These types of investments were designed to provide liquidity through an auction process that reset the applicable interest rates at predetermined periods ranging from 1 to 35 days. This reset mechanism was intended to allow existing investors to continue to own their respective interest in the auction rate security or to gain immediate liquidity by selling their interests at par.

Auctions for investment grade securities held by the Company have failed. However, a failed auction does not represent a default by the issuer. The auction rate securities continue to pay interest in accordance with the terms of the underlying security; however, liquidity will be limited until there is a successful auction or until such time as other markets for these investments develop. The Company has the intent and ability to hold these auction rate securities until liquidity returns to the market. The Company does not believe that the lack of liquidity relating to its auction rate securities will have a material impact on its ability to fund operations.

~~As of~~ September 30, 2017, the Company held auction rate securities with underlying tax-exempt municipal bonds that mature in 2030 and have a fair value and a cost basis of $6.4 million. As of December 31, 2016, the tax-exempt municipal bonds had a fair value of $6.2 million and a cost basis of $6.7 million. The issuer redeemed $150,000 of the auction rate securities during 2014, $275,000 during 2015, $450,000 during 2016 and $325,000 during the second quarter of 2017. These bonds have credit wrap insurance and a credit rating of A by a major credit rating agency.

~~Table of Contents~~

~~The Company valued the auction rate securities at~~ September 30, 2017, using a discounted cash flow model based on the characteristics of the individual securities, which the Company believes yields the best estimate of fair value. The first step in the valuation included a credit analysis of the security which considered various factors, including the credit quality of the issuer, the instrument’s position within the capital structure of the issuing authority and the composition of the authority’s assets, including the effect of insurance and/or government guarantees. Next, the future cash flows of the instruments were projected based on certain assumptions regarding the auction rate market significant to the valuation, including that the auction rate market will remain illiquid and auctions will continue to fail, causing the interest rate to be the maximum applicable rate. This assumption resulted in a discounted cash flow analysis being performed through 2019, the point at which the Company estimates the securities will be redeemed by the municipality. The projected cash flows were then discounted using the applicable yield curve plus a 225 basis point liquidity premium added to the applicable discount rate.

The Company recorded a pre-tax impairment charge of $1.0 million on these auction rate securities in 2011 and subsequent pre-tax increases in fair value of $427,000 during 2014 and $469,000 during the second quarter of 2017. The Company believes that the impairment is temporary and had included the impairment in accumulated other comprehensive loss.

~~Long-Lived Assets~~

During the first quarter of 2016, the Company instituted plans to consolidate its dealership network. The Company recorded an impairment charge related to the value of the real estate in the affected locations and excess real estate in the amount of $7.1 million in the quarter ended March 31, 2016 and $0.4 million in the quarter ended June 30, 2016.

~~The fair value measurements for the Company~~’s long-lived assets are based on Level 3 inputs. Fair values were based on evaluations by a third-party real estate broker that utilized its knowledge and historical experience in real estate markets and transactions.

During 2016, the Company sold four properties with a fair value of $6.1 million. During the first quarter of 2017, the Company sold one property with a fair value of $1.0 million and during the second quarter of 2017, the Company sold two properties with a collective fair value of $1.2 million. During the third quarter of 2017, the Company made the decision to put one of the properties previously classified as “held for sale” with a fair value of $1.4 million back into service. The Company is actively marketing the remaining real estate held for sale.

~~For further discussion of assets held for sale, see Note 10~~ 7– Restructuring Costs of the Notes to Consolidated Financial Statements. The losses in the above table were reported in selling, general and administrative expenses in the Consolidated Statements of Income and Comprehensive Income and were reported under the Truck Segment.

The Company currently has ~~one~~1 reportable business segment - the Truck Segment. The Truck Segment includes the ~~Company~~’sCompany’s operation of a nationwide network of commercial vehicle dealerships that provide an integrated ~~one-stop~~one-stop source for the commercial vehicle needs of its customers, including retail sales of new and used commercial vehicles; aftermarket parts, service and ~~body shop~~collision center facilities; and ~~a wide array of~~ financial services, including the financing of new and used commercial vehicle purchases, insurance products and truck leasing and rentals. The commercial vehicle dealerships are deemed a single reporting unit because they have similar economic characteristics. The Company’s chief operating decision maker considers the entire Truck Segment, not individual dealerships or departments within ~~our~~its dealerships, when making decisions about resources to be allocated to the segment and assessing its performance.

The Company also has revenues attributable to ~~three~~3 other operating segments. These segments include a retail tire company, an insurance agency and a guest ranch operation and are included in the All Other column below. None of these segments has ever met any of the quantitative thresholds for determining reportable segments.

The accounting policies of the segments are the same as those described in the summary of significant accounting policies. The Company evaluates performance based on income before income taxes, not including extraordinary items.

The following table contains summarized information about reportable segment ~~revenue,~~revenues, segment income or loss from continuing operations and segment assets for the periods ended September 30, ~~2017,~~ 2021 and ~~2016~~2020 (in thousands):

The Company had unrecognized income tax benefits totaling ~~$2.4~~$4.5 million as a component of accrued liabilities at as of September 30, ~~2017~~ 2021 and December 31, ~~2016,~~ 2020, the total of which, if recognized, would impact the Company’s effective tax rate. An unfavorable settlement may require a charge to income tax expense and a favorable resolution would be recognized as a reduction to income tax expense. The Company recognizes interest accrued related to unrecognized tax benefits in income tax expense. ~~No amounts were accrued for penalties.~~ The Company had approximately ~~$145,000~~$150,000 accrued for the payment of interest at as of September 30, ~~2017~~ 2021 and December 31, ~~2016.~~2020. NaN amounts were accrued for penalties.

The Company does not anticipate a significant change in the amount of unrecognized tax benefits in the next 12 months. As of September 30, ~~2017,~~ 2021, the tax years ended December 31, ~~2013~~ 2017 through ~~2016, remain~~2020 remained subject to audit by federal tax authorities, and the tax years ended December 31, ~~2012~~ 2016 through ~~2016, remain~~2020, remained subject to audit by state tax authorities.

~~In March~~ ~~2016, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2016-09, “~~~~Compensation~~ 9– ~~Stock Compensation (Topic 718),~~” which changed the accounting for certain aspects of share-based payments to employees. The Company adopted the new standard on January 1, 2017. The new guidance requires excess tax benefits and tax deficiencies to be recognized as income tax benefit or expense in the income statement and presented as an operating activity in the statement of cash flows when the awards are vested or are settled. The Company recorded excess tax benefits of $1.9 million for the three months ended September 30, 2017, and $3.9 million for the nine months ended September 30, 2017, which was recorded as a reduction to income tax expense in the Consolidated Statement of Income and Comprehensive Income. Revenue

9 ~~– Accumulated Other Comprehensive Income~~ ~~(Loss)~~The Company’s revenues are primarily generated from the sale of finished products to customers. Those sales predominantly contain a single delivery element and revenue from such sales is recognized when the customer obtains control, which is typically when the finished product is delivered to the customer. The Company’s material revenue streams have been identified as the following: the sale of new and used commercial vehicles, arrangement of associated commercial vehicle financing and insurance contracts, the performance of commercial vehicle repair services and the sale of commercial vehicle parts. Taxes collected from customers relating to product sales and remitted to governmental authorities are excluded from revenues.

The following ~~tables show~~table summarizes the Company’s disaggregated revenue by revenue source for the three months and nine months ended September 30, 2021 and 2020 (in thousands):

All of the Company's performance obligations and associated revenues are generally transferred to customers at a point in time. The Company did not have any material contract assets or contract liabilities on the balance sheet as of September 30, 2021. Revenues related to commercial vehicle sales, parts sales, commercial vehicle repair service, finance and the majority of the Company’s other revenues are related to the Truck Segment.

The Company leases commercial vehicles to customers primarily over periods of one to ten years. The Company does not separate lease and nonlease components. Nonlease components typically consist of maintenance and licensing for the commercial vehicle. The variable nonlease components are generally based on mileage. Some leases contain an option for the lessee to purchase the commercial vehicle.

The Company’s policy is to depreciate its lease fleet using a straight-line method over each customer’s contractual lease term. The lease unit is depreciated to a residual value that is the estimated fair value of the lease unit at the expiration of the lease term. This policy results in the Company realizing reasonable gross margins while the unit is in service and a corresponding gain or loss on sale when the unit is sold at the end of the lease term.

Sales-type leases are recognized by the Company as lease receivables. The lessee obtains control of the underlying asset and the Company recognizes sales revenue upon lease commencement. The receivable for sales-type leases was $5.4 million as of September 30, 2021, and $5.6 million as of December 31, 2020, and is reflected in Other Assets on the Consolidated Balance Sheet.

Lease and rental income during the three and nine months ended September 30, 2021, and September 30, 2020, consisted of the following (in thousands):

The following table shows the components of accumulated other comprehensive ~~loss, net of tax~~income (loss) (in thousands):

The equity method investment in RTC Canada was valued using the exchange rate of one US Dollar equals 1.2648 Canadian dollars as of September 30, 2021. The adjustment is reflected in Other Assets on the Consolidated Balance Sheet.

10 12– ~~Restructuring Costs~~ Accounts Receivable and Allowance for Credit Losses

~~During~~The Company establishes an allowance for credit losses to present the ~~quarter ended March 31, 2016,~~net amount of accounts receivable expected to be collected. Under Topic 326: Measurement of Credit Losses on Financial Instruments, the Company ~~instituted~~is required to remeasure expected credit losses for financial instruments held on the reporting date based on historical experience, current conditions and reasonable forecasts.

Accounts receivable consists primarily of commercial vehicle sales receivables, manufacturers’ receivables, leasing and parts and service receivables and other trade receivables. The Company maintains an allowance for credit losses based on the probability of default, its historical rate of losses, aging and current economic conditions. The Company writes off account balances when it has exhausted reasonable collection efforts and determined that the likelihood of collection is remote. These write-offs are charged against the allowance for credit losses.

The following table summarizes the changes in the allowance for credit losses (in thousands):

On September 7, 2021, the Company entered into an Asset Purchase Agreement with certain subsidiaries and affiliates of The Summit Truck Group (“Summit”) to acquire full-service commercial vehicle dealerships and Idealease franchises in Arkansas, Kansas, Mississippi, Missouri, Oklahoma, Tennessee and Texas. The acquisition includes Summit’s dealerships representing International, IC Bus, Idealease, Isuzu and other commercial vehicle manufacturers. The Company estimates that the purchase price will be approximately $223.0 million, excluding the anticipated purchase of certain real property of the Seller for approximately $60.0 million pursuant to one or more real property purchase agreements. At the closing, the Company anticipates that it will finance approximately $114.0 million of the purchase price. The closing of the transaction, expected in December 2021, is subject to, amongst other things, manufacturers’ approval, various regulatory approvals and the satisfaction of the closing conditions set forth in the asset purchase agreement. The Company does not expect to ultimately own Summit’s dealerships in Oklahoma or Mississippi.

On September 14, 2021, the Company entered into a credit agreement (“the WF Credit Agreement”) with the Lenders signatory thereto (the “WF Lenders”) and Wells Fargo Bank, National Association (“WF”), as administrative agent (in such capacity, the “WF Agent”). Pursuant to the terms of the WF Credit Agreement, the WF Lenders have agreed to make up to $250.0 million of revolving credit loans for certain of the Company’s capital expenditures, including commercial vehicle purchases for the Company’s Idealease lease and rental fleet, and general working capital needs. The Company expects to use the revolving credit loans available under the WF Credit Agreement primarily for the purpose of purchasing commercial vehicles for the Company’s Idealease lease and rental fleet.

The interest associated with the WF Credit Agreement was $1.2 million in the third quarter of 2021 and is recorded in interest expense on the financial statements. The WF Credit Agreement is a general borrowing facility, whereas prior to the WF Credit Agreement, interest expense associated with the Company’s Idealease lease and rental fleet was recorded in cost of sales as the borrowings were directly related to each lease and rental vehicle. This change in presentation of interest expense will result in increased gross margins from the Company’s Idealease lease and rental sales.

On October 1, 2021, the Company entered into that certain Amended and Restated Inventory Financing and Purchase Money Security Agreement with PLC, a division of PACCAR Financial Corp. (the “PLC Agreement”). Pursuant to the terms of the PLC Agreement, PLC agreed to make up to $300.0 million of revolving credit loans to finance certain of our capital expenditures, including commercial vehicle purchases and other equipment to be leased or rented through the Company’s PacLease franchises. The interest associated with the PLC Agreement will be recorded in interest expense on the financial statements because the PLC Agreement is a general borrowing facility. This change in presentation of interest expense will result in increased gross margins from the Company’s PacLease lease and rental sales.

ITEM 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

Rush Enterprises, Inc. was incorporated in Texas in 1965 and consists of one reportable segment, the Truck Segment, and conducts business through its subsidiaries. Our principal offices are located at 555 IH 35 South, Suite 500, New Braunfels, Texas 78130.

We are a full-service, integrated retailer of commercial vehicles and related services. The Truck Segment includes our operation of a network of commercial vehicle dealerships under the name “Rush Truck Centers.” Rush Truck Centers primarily sell commercial vehicles manufactured by Peterbilt, International, Hino, Ford, Isuzu, IC Bus or Blue Bird. Through our strategically located network of Rush Truck Centers, we provide one-stop service for the needs of our commercial vehicle customers, including retail sales of new and used commercial vehicles, aftermarket parts sales, service and repair facilities, financing, leasing and rental, and insurance products.

Our Rush Truck Centers are principally located in high traffic areas throughout the United States. Since commencing operations as a Peterbilt heavy-duty truck dealer in 1966, we have grown to operate over 100 Rush Truck Centers in 22 states.

Our business strategy consists of providing solutions to the commercial vehicle industry through our network of commercial vehicle dealerships. We offer an integrated approach to meeting customer needs by providing service, parts and collision repairs in addition to new and used commercial vehicle sales and leasing, plus financial services, vehicle upfitting, CNG fuel systems and vehicle telematics products. We intend to continue to implement our business strategy, reinforce customer loyalty and remain a market leader by continuing to develop our Rush Truck Centers as we expand our product offerings and extend our dealership network through strategic acquisitions of new locations and ~~incurred pre-tax expenses~~opening new dealerships to enable us to better serve our customers.

Our dealership network has remained operational since the beginning of the COVID-19 pandemic. While the COVID-19 pandemic is not over, business conditions have improved significantly since the second quarter of 2020. However, our industry continues to be impacted by supply chain issues generally believed to be attributable to the COVID-19 pandemic that are negatively affecting new commercial vehicle production and the availability of aftermarket parts.

All of the commercial vehicle manufacturers that we represent resumed operations following any COVID-19 related shutdowns in 2020. However, supply chain delays related to commercial vehicle components have forced some of the manufacturers we represent to temporarily cease production at times and will limit the commercial vehicle industry’s ability to meet demand for commercial vehicles throughout the remainder of 2021 and into 2022. The decrease in the supply of new commercial vehicles has resulted in increased demand for used commercial vehicles.

With respect to our parts, service and collision center (collectively, “Aftermarket Products and Services”) departments, with some minor exceptions, our parts supply chain has remained relatively uninterrupted and our parts sales are back to pre-pandemic levels. We believe that the investments we made over the years with respect to our aftermarket strategic initiatives enabled us to mitigate some of the impact of the COVID-19 pandemic on our Aftermarket Products and Service business. However, with respect to parts availability going forward, we are dependent on our manufacturers and future production levels of certain parts and components are uncertain at this time. Although the supply chain disruptions are only impacting a small percentage of the parts we sell, any delay we experience in receiving a part has a corresponding delay in our completion of services on the commercial vehicle for which the part was ordered.

With respect to our rental and leasing operations, in 2020, we allowed certain credit-worthy customers serving industries that were dramatically impacted by the COVID-19 pandemic to skip up to three months of lease payments and either extend the lease term by three months or increase the remaining payments to keep the same lease term. These customers have resumed payments. Revenues from our rental and leasing operations are back to pre-pandemic levels.

As of September 30, 2021, we had $259.7 million in cash. For further discussion of our liquidity, see the Liquidity and Capital Resources discussion set forth herein.

A.C.T. Research Co., LLC (“A.C.T. Research”), a commercial vehicle industry data and forecasting service provider, currently forecasts new U.S. Class 8 retail truck sales to be 228,500 units in 2021, which would represent a 16.8% increase compared to 2020. While demand for new commercial vehicles is currently strong, we believe that component supply chain issues will continue to delay production, pushing new Class 8 truck deliveries into 2022, and negatively impacting our new Class 8 truck sales in the fourth quarter of this year. In addition, we have been informed by our manufacturers that production of commercial vehicles in 2022 will be allocated to all of their dealers based on historical purchases. While we do not yet know our allocation for 2022, we believe that our allocation of commercial vehicles will not be less than the number of commercial vehicles we expect to sell in 2021.

We expect our market share of new Class 8 truck sales to range between 5.0% and 5.2% in 2021. This market share percentage would result in the sale of approximately ~~$8.1 million related~~11,400 to ~~restructuring activities.~~11,900 of new Class 8 trucks in 2021, based on A.C.T. Research’s current U.S. retail sales estimate of 228,500 units.

With respect to new U.S. Class 4 through 7 retail commercial vehicle sales, A.C.T. Research currently forecasts sales to be 251,000 units in 2021, which would represent an 8.2% increase compared to 2020. We expect our market share of new Class 4 through 7 commercial vehicle sales to range between 4.0% and 4.3% in 2021. This market share percentage would result in the sale of approximately 10,000 to 10,800 of new Class 4 through 7 commercial vehicles in 2021, based on A.C.T. Research’s current U.S. retail sales estimates of 251,000 units.

We expect to sell approximately 1,600 light-duty vehicles and approximately 7,200 to 7,400 used commercial vehicles in 2021. We expect lease and rental revenue to increase 5% to 7% during 2021, compared to 2020.

While parts supply chain constraints are expected to negatively impact the Aftermarket Products and Services industry for the remainder of 2021, we do not believe these constraints will have a significant overall effect on our Aftermarket Products and Services revenues. We believe our Aftermarket Products and Services revenues will increase 10% to 12% in 2021, compared to 2020.

In October 2021, we acquired an independent parts and service facility in Victorville, California that will be converted into a full service Peterbilt dealership. We also plan to acquire a full-service Hino and Isuzu dealership in Elk Grove, Illinois in November 2021. Additionally, on September 7, 2021, we entered into an agreement with certain subsidiaries and affiliates of The ~~restructuring costs included $2.7 million associated~~Summit Truck Group (“Summit”) to acquire full-service commercial vehicle dealerships and Idealease franchises in Arkansas, Kansas, Mississippi, Missouri, Oklahoma, Tennessee and Texas. The acquisition includes Summit’s dealerships representing International, IC Bus, Idealease, Isuzu and other commercial vehicle manufacturers. The closing of the transaction is subject to, amongst other things, manufacturers’ approval, various regulatory approvals and the satisfaction of the closing conditions set forth in the asset purchase agreement, but we expect the transaction to close in December 2021. We do not expect to ultimately own Summit’s dealerships in Oklahoma or Mississippi.

Our discussion and analysis of our financial condition and results of operations are based on our consolidated financial statements, which have been prepared in accordance with ~~impairment charges~~U.S. generally accepted accounting principles. The preparation of these consolidated financial statements requires us to ~~certain fixed~~make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. There can be no assurance that actual results will not differ from those estimates. We believe the following accounting policies affect our more significant judgments and estimates used in the preparation of our consolidated financial statements.

Inventories are stated at the lower of cost or net realizable value. Cost is determined by specific identification of new and used commercial vehicle inventory and by the first-in, first-out method for tires, parts and accessories. As the market value of our inventory typically declines over time, reserves are established based on historical loss experience and market trends. These reserves are charged to cost of sales and reduce the carrying value of our inventory on hand. An allowance is provided when it is anticipated that cost will exceed net realizable value less a reasonable profit margin.

Goodwill is tested for impairment by reporting unit utilizing a two-step process at least annually, or more frequently when events or changes in circumstances indicate that the asset might be impaired. The first step requires us to compare the fair value of the ~~real estate underlying~~reporting unit (we consider our Truck Segment to be a reporting unit for purposes of this analysis), which is the ~~affected locations, which was reported in~~same as the segment, to the respective carrying value. If the fair value of the reporting unit exceeds its carrying value, the goodwill is not considered impaired. If the carrying value is greater than the fair value, there is an indication that impairment may exist and a second step is required. In the second step of the analysis, the implied fair value of the goodwill is calculated as the excess of the fair value of a reporting unit over the fair values assigned to its assets and liabilities. If the implied fair value of goodwill is less than the carrying value of the reporting unit’s goodwill, the difference is recognized as an impairment loss.

We determine the fair value of our reporting unit using the discounted cash flow method. The discounted cash flow method uses various assumptions and estimates regarding revenue growth rates, future gross margins, future selling, general and administrative expenses and an estimated weighted average cost of capital. The analysis is based upon available information regarding expected future cash flows of each reporting unit discounted at rates consistent with the cost of capital specific to the reporting unit. This type of analysis contains uncertainties because it requires us to make assumptions and to apply judgment regarding our knowledge of our industry, information provided by industry analysts and our current business strategy in light of present industry and economic conditions. If any of these assumptions change, or fail to materialize, the ~~Consolidated Statements of Income and Comprehensive Income for~~resulting decline in our estimated fair value could result in a material impairment charge to the ~~nine months ended September 30, 2016.~~goodwill associated with the reporting unit.

~~In addition,~~We do not believe there is a reasonable likelihood that there will be a material change in the ~~Company classified~~future estimates or assumptions we used to test for impairment losses on goodwill. However, if actual results are not consistent with our estimates or assumptions, or certain ~~excess real estate as held for sale, which resulted~~events occur that might adversely affect the reported value of goodwill in the future, we may be exposed to an impairment charge ~~of $5.0 million, which was reported in selling, general and administrative expenses in the Consolidated Statements of Income and Comprehensive Income for the nine months ended September 30, 2016.~~that could be material.

Goodwill was tested for impairment during the ~~Company sold four~~fourth quarter of ~~the properties previously classified as held for sale with a~~2020 and no impairment was required. The fair value of ~~$6.1 million. During~~our reporting unit exceeded the ~~first quarter~~carrying value of ~~2017,~~its net assets. As a result, we were not required to conduct the ~~Company sold~~second step of the impairment test. We do not believe our reporting unit is at risk of failing step one of the properties with a fair value of $1.0 million and during the second quarter of 2017, the Company sold two of the properties with a collective fair value of $1.2 million. During the third quarter of 2017, the Company made the decision to put one of the properties previously classified as “held for sale” with a fair value of $1.4 million back into service. As of September 30, 2017, the remaining real estate associated with the restructuring activities is included in assets held for sale on the Consolidated Balance Sheets.impairment test.

We are partially self-insured for a portion of the claims related to our property and casualty insurance programs, which requires us to make estimates regarding expected losses to be incurred. We engage a third-party administrator to assess any open claims and we adjust our accrual accordingly on a periodic basis. We are also partially self-insured for a portion of the claims related to our workers’ compensation and medical insurance programs. We use actuarial information provided from third-party administrators to calculate an accrual for claims incurred, but not reported, and for the remaining portion of claims that have been reported.

Changes in the frequency, severity and development of existing claims could influence our reserve for claims and financial position, results of operations and cash flows. We do not believe there is a reasonable likelihood that there will be a material change in the estimates or assumptions we used to calculate our self-insured liabilities. However, if actual results are not consistent with our estimates or assumptions, we may be exposed to losses or gains that could be material.

Management’s judgment is required to determine the provisions for income taxes and to determine whether deferred tax assets will be realized in full or in part. Deferred income tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. When it is more likely than not that all or some portion of specific deferred income tax assets will not be realized, a valuation allowance must be established for the amount of deferred income tax assets that are determined not to be realizable. Accordingly, the facts and financial circumstances impacting deferred income tax assets are reviewed quarterly and management’s judgment is applied to determine the amount of valuation allowance required, if any, in any given period.

Our income tax returns are periodically audited by tax authorities. These audits include questions regarding our tax filing positions, including the timing and amount of deductions. In ~~March~~ ~~2016,~~evaluating the ~~FASB issued ASU No. 2016-09, which changed the accounting~~exposures associated with our various tax filing positions, we adjust our liability for ~~certain aspects of share-based payments to employees. The Company adopted the new standard on January 1, 2017. The new guidance requires excess~~unrecognized tax benefits and income tax ~~deficiencies to be recorded~~provision in the ~~income statement~~period in which an uncertain tax position is effectively settled, the statute of limitations expires for the relevant taxing authority to examine the tax position or when ~~the awards vest or are settled. The Company recorded excess~~more information becomes available.

Our liability for unrecognized tax benefits contains uncertainties because management is required to make assumptions and to apply judgment to estimate the exposures associated with our various filing positions. Our effective income tax rate is also affected by changes in tax law, the level of ~~$1.9 million~~earnings and the results of tax audits. Although we believe that the judgments and estimates are reasonable, actual results could differ, and we may be exposed to losses or gains that could be material. An unfavorable tax settlement would generally require use of our cash and result in an increase in our effective income tax rate in the ~~three months ended September 30, 2017 and $3.9 million~~period of resolution. A favorable tax settlement would be recognized as a reduction in our effective income tax rate in the ~~nine months ended September 30, 2017, which was recorded in the Consolidated Statements~~period of ~~Income and Comprehensive Income. In addition, cash flows related to excess tax benefits will no longer be separately classified as a financing activity apart from other~~resolution. Our income tax ~~cash flows. The standard also allows~~expense includes the ~~Company~~impact of reserve provisions and changes to ~~repurchase more of an employee’s shares for tax withholding purposes without triggering liability accounting, clarifies~~reserves that ~~all cash payments made on an employee’s behalf for withheld shares should be presented~~we consider appropriate, as ~~a financing activity on its cash flows statement, and provides an accounting policy election to account for forfeitures~~well as ~~they occur. The Company did not elect to make an accounting policy change to recognize forfeitures as they occur and will continue to estimate forfeitures. The Company adopted the amendments~~ related ~~to ASU 2016-09 prospectively and prior periods have not been adjusted.~~

~~In February 2016, the FASB issued ASU No. 2016-02, “~~~~Leases (Topic 842),~~” which is intended to increase the transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. In order to meet that objective, the new standard requires recognition of the assets and liabilities that arise from leases. A lessee will be required to recognize on the balance sheet the assets and liabilities for leases with lease terms of more than 12 months. The new standard is effective for public companies for fiscal years beginning after December 15, 2018, and interim periods within those years, with early adoption permitted. The Company is currently evaluating the effect that adopting this standard will have on our financial statements and related disclosures. The Company will adopt ASU 2016-02 on January 1, 2019.interest.

Effective January 1, 2018, we adopted ASU ~~No.~~ 2014-09, “~~Revenue from Contracts with Customers~~Insurance Accruals~~(Topic 606)~~,” which amended the accounting standards for revenue recognition. ASU 2014-09 is based on principles that govern the recognition of revenue at an amount an entity expects to be entitled to when products are transferred to customers. ASU 2014-09 will be effective for the Company beginning in its first quarter of 2018, and early adoption is permitted. The ASU provides two transition methods: (i) retrospectively to each prior reporting period presented; or (ii) modified retrospectively with the cumulative effect of initially applying this ASU recognized at the date of initial application.

~~In 2016, the Company established a cross-functional team with representatives from its major revenue streams to review~~ its current accounting policies and practices, assess the effect of the standard on our revenue contracts and identify potential differences. The Company’s internal implementation team has substantially completed its initial review of the likely impacts that the application of the amendments in this ASU will have on its consolidated financial statements. The Company’s revenues are primarily generated from the sale of finished products to customers. Those sales predominantly contain a single delivery element and revenue for such sales is recognized when the customer obtains control. The team has initially identified the Company’s material revenue streams to be the sale of new and used commercial vehicles; arrangement of associated commercial vehicle financing and insurance contracts; the performance of commercial vehicle repair services; and the sale of commercial vehicle parts. The Company’s implementation team is in the preliminary stages of evaluating the additional disclosure requirements of the ASU, as well as the change, if any, to the Company’s underlying accounting and financial reporting systems and processes necessary to support the recognition and disclosure requirements. The Company expects to identify and implement the necessary changes, if any, during 2017. At this time, based on this review, the Company does not expect the adoption to materially impact its consolidated financial statements. The Company will adopt ASU 2014-09 on January 1, 2018 and will use the modified retrospective method.

Effective January 1, 2018, we adopted ASU 2014-09, “Revenue from Contracts with Customers(“Topic 606”),” using the modified retrospective transition method. This standard applies to all contracts with customers, except for contracts that are within the scope of other standards, such as leases, insurance, collaboration arrangements and financial instruments. Under Topic 606, we recognize revenue when our customer obtains control of promised goods or services, in an amount that reflects the consideration which we expect to receive in exchange for those goods or services. To determine revenue recognition for arrangements that we determine are within the scope of Topic 606, we perform the following five steps: (i) identify the contract with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) we satisfy a performance obligation. We only apply the five-step model to contracts when it is probable that we will collect the consideration we are entitled to in exchange for the goods or services we transfer to the customer. At contract inception, once the contract is determined to be within the scope of Topic 606, we assess the goods or services promised within each contract and determine those that are performance obligations. We then assess whether each promised good or service is distinct and recognize as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied.

When available, we use the rate implicit in the lease to discount lease payments to present value; however, most of our leases do not provide a readily determinable implicit rate. Therefore, we must estimate our incremental borrowing rate to discount the lease payments based on information available at lease commencement.

We lease commercial vehicles that we own to customers. Lease and rental revenue is recognized over the period of the related lease or rental agreement. Variable rental revenue is recognized when it is earned.

All trade receivables are reported on the consolidated balance sheet at their cost basis adjusted for any write-offs and net of allowances for credit losses. We maintain allowances for credit losses, which represent an estimate of expected losses over the remaining contractual life of our receivables after considering current market conditions and estimates for supportable forecasts, when appropriate. The estimate is a result of our ongoing assessments and evaluations of collectability, historical loss experience, and future expectations in estimating credit losses in each of our receivable portfolios (commercial vehicle receivables, manufacturers’ receivables, parts and service receivables, leasing receivables and other trade receivables). For trade receivables, we use the probability of default and our historical loss experience rates by portfolio and apply them to a related aging analysis while also considering customer and/or economic risk where appropriate. Determination of the proper amount of allowances by portfolio requires management to exercise judgment about the timing, frequency and severity of credit losses that could materially affect the provision for credit losses and, as a result, net earnings. The allowances take into consideration numerous quantitative and qualitative factors that include receivable type, historical loss experience, collection experience, current economic conditions, estimates for supportable forecasts (when appropriate) and credit risk characteristics.

The following discussion and analysis includes our historical results of operations for the three months and nine months ended September 30, ~~2017~~2021 and ~~2016.~~2020.

The following table sets forth ~~for the periods indicated~~ certain financial data as a percentage of total ~~revenues:~~revenues for the periods indicated:

The following table sets forth for the periods indicated the percent of gross profit by revenue source:

The following table sets forth the unit sales and revenues for new heavy-duty, new medium-duty, new light-duty and used commercial vehicles and our absorption ratio (revenue in millions):

Management uses several performance metrics to evaluate the performance of our commercial vehicle dealerships and considers Rush Truck Centers’ “absorption ratio” to be of critical importance. Absorption ratio is calculated by dividing the gross profit from ~~the parts, service and body shop (collectively, “Aftermarket~~our Aftermarket Products and ~~Services”)~~Services departments by the overhead expenses of all of a dealership’s departments, except for the selling expenses of the new and used commercial vehicle departments and carrying costs of new and used commercial vehicle inventory. When 100% absorption is achieved, all of the gross profit from the sale of a commercial vehicle, after sales commissions and inventory carrying costs, directly impacts operating profit. ~~In 1999, our commercial vehicle dealerships’ absorption ratio was approximately 80%. Since 1999, we have made a concerted effort to increase our absorption ratio.~~ Our commercial vehicle dealerships achieved a ~~120.9%~~134.0% absorption ratio for the third quarter of ~~2017~~2021 compared to a ~~112.6%~~119.4% absorption ratio for the third quarter of ~~2016.~~2020.

Three Months Ended September 30, ~~201~~72021 Compared to Three Months Ended September 30, ~~201~~6

The growth in Aftermarket Products and Services revenues in the third quarter was primarily the result of strong general economic conditions and our successful execution of certain strategic initiatives. We expect Aftermarket Products and Services revenues to remain solid during the remainder of 2017, despite the seasonal decline we typically experience during the fourth quarter of the year. We remain focused on our long-term plans and strategic initiatives, which include expanding our all-makes parts and service business.

~~Class 8 new truck sales were strong during the third quarter of 2017 primarily due to increased activity from customers in the energy industry~~. Additionally, commercial vehicle sales activity remains solid in construction, refuse, over-the-road freight and the majority of the other industries we support around the country. Used commercial vehicle inventory valuations have stabilized, and we believe that our used commercial vehicle inventory is priced appropriately to support market dynamics and new commercial vehicle sales. We believe our Class 8 and medium-duty new commercial vehicle sales will remain strong in the fourth quarter and into 2018.2020

Total r~~evenues~~revenues increased ~~$161.4~~$88.0 million, or ~~14.7%~~7.5%, in the third quarter of ~~2017,~~2021, compared to the third quarter of ~~2016.~~2020.

Our Aftermarket Products and Services revenues ~~increased $39.4~~totaled $463.0 million ~~or 11.7%,~~ in the third quarter of ~~2017, compared to~~2021, up 15.7% from the third quarter of ~~2016,~~2020. This increase was primarily ~~as a result~~due to the overall continued recovery of the ~~factors described above. We expect our Aftermarket Products~~national economy and ~~Services revenues to remain~~ strong ~~in the fourth quarter of 2017.~~demand for aftermarket parts and services.

Revenues from sales of new and used commercial vehicles increased ~~$120.2~~$17.6 million, or ~~17.2%~~2.5%, in the third quarter of ~~2017,~~2021, compared to the third quarter of ~~2016,~~2020. This increase was also primarily ~~as a result~~due to the continued recovery of the ~~factors described above.~~national economy, which has led to strong freight rates throughout the country and strong demand for commercial vehicles.

We sold ~~3,647 heavy-duty~~2,537 new Class 8 trucks in the third quarter of ~~2017,~~2021, a ~~20.6% increase~~1.8% decrease compared to ~~3,024 heavy-duty~~2,584 new Class 8 trucks sold in the third quarter of ~~2016.~~2020. Our new Class 8 truck sales were negatively impacted by industry-wide new truck production constraints. According to A.C.T. Research, ~~Co., LLC (“A.C.T. Research”), a commercial vehicle industry data and forecasting service provider,~~retail sales in the U.S. Class 8 truck market increased ~~11.2%~~2.5% in the third quarter of ~~2017~~2021, compared to the third quarter of 2016. A.C.T. Research currently forecasts U.S. retail sales of Class 8 trucks of approximately 190,000 units in 2017, 218,000 units in 2018, and 226,000 units in 2019, compared to approximately 197,000 units in 2016. Our share of the U.S. Class 8 truck sales market was approximately 5.5% in 2016. We expect our U.S. Class 8 truck sales market share to range between 6.5% and 7.0% in 2017. This market share percentage would result in the sale of approximately 12,400 to 13,300 Class 8 trucks in 2017 based on A.C.T. Research’s current U.S. retail sales estimate of 190,000 units.2020.

We sold ~~2,828~~2,792 new Class 4 through 7 medium-duty commercial vehicles, including ~~466~~410 buses, in the third quarter of ~~2017,~~2021, a ~~14.5% increase~~5.1% decrease compared to ~~2,469~~2,941 new medium-duty commercial vehicles, including ~~416~~429 buses, in the third quarter of ~~2016.~~2020. Our third quarter 2021 new Class 4 through 7 commercial vehicle sales were negatively impacted by industry-wide new truck production constraints. A.C.T. Research estimates that unit sales of new Class 4 through 7 commercial vehicles in the U.S. ~~increased~~decreased approximately ~~9.0%~~2.2% in the third quarter of ~~2017,~~2021, compared to the third quarter of 2016. A.C.T. Research currently forecasts U.S. retail sales of Class 4 through 7 commercial vehicles of approximately 238,500 units in 2017, 242,000 units in 2018, and 249,000 in 2019. In 2016, we achieved a 4.9% share of the U.S. Class 4 through 7 commercial vehicle market. We expect our market share to range between 4.5% and 5.0% of the U.S. Class 4 through 7 commercial vehicle sales in 2017. This market share percentage would result in the sale of approximately 10,700 to 11,900 of Class 4 through 7 commercial vehicles in 2017 based on A.C.T. Research’s current U.S. retail sales estimates of 238,500 units.2020.

We sold ~~447~~361 light-duty vehicles in the third quarter of ~~2017,~~2021, a ~~14.5% decrease~~27.6% increase compared to ~~523~~283 light-duty vehicles sold in the third quarter of ~~2016. We expect to sell approximately 1,700 light-duty vehicles in 2017.~~2020.

We sold ~~1,743~~1,712 used commercial vehicles in the third quarter of ~~2017,~~2021, a ~~2.9%~~16.7% decrease compared to ~~1,795~~2,055 used commercial vehicles in the third quarter of ~~2016. We expect to sell approximately 6,200 to 7,000~~2020. Demand for used commercial vehicles remained strong in ~~2017.~~the third quarter of 2021, driven in large part by production delays for new Class 8 trucks, however, the number of used commercial vehicles we will be able to sell depends on our ability to acquire quality used commercial vehicle inventory. We believe used truck values will decrease when new truck production increases; however, we believe demand for used trucks will remain strong through 2021 and into 2022.

Commercial vehicle lease and rental revenues increased ~~$2.2~~$4.8 million, or ~~4.2%~~8.2%, in the third quarter of ~~2017,~~2021, compared to the third quarter of ~~2016. We expect~~2020. The increase is primarily due to increased rental fleet utilization and strong demand for vehicles to lease, ~~and rental revenues~~which is partly due to ~~increase between 3.0% and 6.0% during 2017, compared to 2016.~~the limited supply of new commercial vehicles.

Finance and insurance revenues ~~decreased 2.0%~~increased $1.2 million, or 21.6%, in the third quarter of ~~2017,~~2021, compared to the third quarter of ~~2016. Traditionally,~~2020. We expect finance and insurance revenues to fluctuate proportionately with our new and used commercial vehicle ~~sales. However,~~sales in ~~2017 a significant portion of our sales have been to large fleet customers who do not finance trucks through us or our network of lenders.~~2021. Finance and insurance revenues have limited direct costs and, therefore, contribute a disproportionate share toof our operating profits.

Gross profit increased ~~$38.7~~$69.8 million, or ~~21.4%~~32.9%, in the third quarter of ~~2017,~~2021, compared to the third quarter of ~~2016.~~2020. Gross profit as a percentage of sales increased to ~~17.5%~~22.3% in the third quarter of ~~2017,~~2021, from ~~16.5%~~18.0% in the third quarter of ~~2016.~~2020. This increase in gross profit as a percentage of sales is a result of widespread increased gross margins inacross all of our ~~Aftermarket Products and Services business, commercial vehicle sales and truck lease and rental sales.~~operations.

Gross margins from our Aftermarket Products and Services operations increased to ~~36.8%~~39.3% in the third quarter of ~~2017,~~2021, from ~~36.1%~~35.4% in the third quarter of ~~2016.~~2020, which is primarily related to the increase in parts rebates from parts suppliers and increases in parts list pricing by the manufacturers we represent, which lead to increased margins on parts sales with respect to inventory acquired prior to the manufacturers’ price increases, compared to the third quarter of 2020. Gross profit for the Aftermarket Products and Services departments increased to ~~$138.4~~$182.2 million in the third quarter of ~~2017,~~2021, from ~~$121.5~~$141.9 million in the third quarter of ~~2016.~~2020. Historically, gross margins on parts sales range from 27% to 28% and gross margins on service and ~~body shop~~collision center operations range from 67% to 68%. Gross profits from parts sales represented ~~57%~~62.4% of total gross profit for Aftermarket Products and Services operations in the third quarter of ~~2017~~2021 and ~~56%~~58.8% in the third quarter of ~~2016.~~2020. Service and ~~body shop~~collision center operations represented ~~43%~~37.6% of total gross profit for Aftermarket Products and Services operations in the third quarter of ~~2017~~2021 and ~~44%~~41.2% in the third quarter of ~~2016. We expect blended gross margins on Aftermarket Products and Services operations to range from 36.3% to 36.5% during 2017.~~2020.

Gross margins on new Class 8 truck sales increased to 8.7% in the third quarter of 2021, from 7.8% in the third quarter of ~~2017, from 6.9% in~~2020. This increase is primarily due to strong demand for Class 8 trucks and the mix of purchasers during the third quarter of ~~2016. This increase is attributable to the sales mix in the third quarter of 2017, which consisted of increased sales to vocational customers that are traditionally associated with higher margins.~~2021. In ~~2017,~~2021, we expect overall gross margins from new Class 8 truck sales of approximately ~~7.5%~~8.0% to ~~8.0%~~9.0%.

Gross margins on ~~medium-duty~~new Class 4 through 7 commercial vehicle sales ~~decreased~~increased to ~~5.4%~~8.0% in the third quarter of ~~2017,~~2021, from ~~6.7%~~5.9% in the third quarter of ~~2016.~~2020. This ~~decrease~~increase is ~~attributable~~primarily due to the mix of ~~products sold~~purchasers during the third quarter of ~~2017.~~2021. For ~~2017,~~2021, we expect overall gross margins from new medium-duty commercial vehicle sales of approximately ~~5.5%~~6.5% to ~~6.0%~~7.5%, but this will largely depend upon the mix of purchasers and types of vehicles sold.

Gross margins on used commercial vehicle sales increased to ~~11.9%~~19.7% in the third quarter of ~~2017,~~2021, from ~~4.8%~~12.0% in the third quarter of ~~2016.~~2020. This increase isin margins in the third quarter of 2021 was primarily ~~related~~due to the ~~stabilization~~increase in used truck values due to strong demand for used commercial vehicles. The lower margins that we recognized in 2020 were due to weak demand for used trucks in early 2020 caused by the beginning of the COVID-19 pandemic and the write-down of used truck inventory values ~~in recent months.~~to account for extremely weak market conditions at that time. We expect margins on used commercial vehicles to ~~range between 9.5% and 10.5% during 2017.~~be approximately 12% to 16% for the remainder of 2021.

Gross margins from truck lease and rental sales increased to ~~17.3%~~25.1% in the third quarter of ~~2017,~~2021, from ~~12.6%~~14.4% in the third quarter of ~~2016.~~2020. This increase is primarily related to increased rental fleet utilization and ~~improvement~~changes to the way we finance commercial vehicles for our lease and rental fleet. In the third quarter of 2021, we entered into a credit agreement with Wells Fargo Bank, N.A. in the ~~performance~~amount of $250.0 million (the “WF Credit Agreement”) that allows us to finance a portion of our ~~full service leases. We expect~~Idealease lease and rental fleet through a general borrowing facility. The interest associated with the WF Credit Agreement is recorded in interest expense on the financial statements and was $1.2 million in the third quarter of 2021. Prior to the WF Credit Agreement, interest expense associated with our Idealease lease and rental fleet was recorded in cost of sales as the borrowings were directly related to each lease and rental vehicle. This change in presentation of interest expense will result in increased gross margins from our Idealease truck lease and rental ~~sales~~sales. In October of ~~approximately 15.5% to 16.5% during 2017.~~2021, we entered into a similar credit agreement with PACCAR Leasing Company (“PLC”) in the amount of $300.0 million for our PacLease lease and rental fleet. Our policy is to depreciate our lease and rental fleet using a ~~straight line~~straight-line method over each customer’s contractual lease term. ~~The~~Each lease unit is depreciated to a residual value that approximates fair value at the expiration of the lease term. This policy results in ~~the Company~~us realizing reasonable gross margins while the unit is in service and a corresponding gain or loss on sale when the unit is sold at the end of the lease term.

Finance and insurance revenues and other income, as described above, have limited direct costs and, therefore, contribute a disproportionate share of gross profit.

Selling, General and Administrative (“SG&A”) expenses increased ~~$17.0~~$24.4 million, or ~~11.9%~~15.7%, in the third quarter of ~~2017,~~2021, compared to the third quarter of ~~2016. In~~2020. This increase resulted from increased personnel expense and increased selling expense, compared to 2020. SG&A expenses as a percentage of total revenues increased to 14.2% in the third quarter of ~~2017, SG&A expenses equaled 12.7%~~2021, from 13.2% in the third quarter of ~~total revenue.~~2020. Annual SG&A expenses as a percentage of total revenues have ~~recently~~ ranged from ~~12.1%~~12.4% to ~~14.7%. In general, when new and used commercial vehicle revenues decrease as a percentage of total revenues, SG&A expenses as a percentage of total revenues will be at, or exceed,~~14.0% over the ~~higher end of this range.~~last five years. For ~~2017,~~2021, we expect SG&A expenses as a percentage of total revenues to range from ~~13.4%~~13.0% to ~~14.2%~~14.0%, due to the increase in revenues from sales of new and used commercial vehicles and Aftermarket Products and Services. For 2021, we expect the selling portion of SG&A expenses to be approximately 25.0% to 30.0% of new and used commercial vehicle gross profit.

Depreciation and amortization expense decreased ~~$0.6~~$1.3 million, or ~~4.4%~~8.9%, in the third quarter of ~~2017,~~2021, compared to the third quarter of ~~2016.~~2020.

Net interest expense decreased ~~$0.2~~$0.8 million, or ~~5.6%~~74.3%, in the third quarter of ~~2017,~~2021, compared to the third quarter of ~~2016. Net interest expense~~2020. This decrease was primarily due to the decrease in ~~2017 will depend on~~floorplan liability related to lower commercial vehicle inventory levels, the product mix of our commercial vehicle inventory and the ~~amount~~reduction in our real estate debt. During the third quarter of ~~cash available to make prepayments on~~2021, a higher portion of our ~~floor plan arrangements.~~vehicle inventory was from commercial vehicle manufacturers that were offering more favorable floorplan terms than in the third quarter of 2020.

As a result of the factors described above, income before income taxes increased ~~$21.0~~$47.9 million, or ~~86.5%~~109.1%, in the third quarter of ~~2017,~~2021, compared to the third quarter of ~~2016.~~2020.

Income taxes increased ~~$6.1~~$12.5 million, or ~~65.0%~~124.7%, in the third quarter of ~~2017,~~2021, compared to the third quarter of ~~2016, as a result of the factors described above. ASU 2016-09~~ ~~“Compensation – Stock Compensation (Topic 718)”~~ requires excess tax benefits and tax deficiencies to be recorded in the income statement when equity awards issued pursuant to our equity compensation plans vest or are settled. We recorded a $1.9 million tax benefit in the third quarter of 2017, which reduced income tax expense.2020. We provided for taxes at a ~~38.75%~~24.75% effective rate in the third quarter of ~~2017~~2021 and 22.7% in the third quarter of ~~2016.~~2020. We expect our effective tax rate to be approximately ~~38.5%~~23.0% to ~~39.0%~~24.0% of pretax income in ~~2017.~~2021.

Our short-term cash requirements are primarily for working capital, inventory financing, the renovation and expansion of existing facilities and the construction or purchase of new facilities. Historically, these cash requirements have been met through the retention of profits, borrowings under our floor plan arrangements and bank financings. As of September 30, ~~201~~7,2021, we had working capital of approximately ~~$180.3~~$405.3 million, including ~~$127.9~~$259.7 million in cash, available to fund our operations. We believe that these funds, together with expected cash flows from operations, are sufficient to meet our operating requirements for at least the next twelve months. From time to time, we utilize our excess cash on hand to pay down our outstanding borrowings under our floor plan credit agreement with BMO Harris Bank N.A. (“BMO Harris”) (the “Floor Plan Credit Agreement”), and the resulting interest earned is recognized as an offset to our gross interest expense under the Floor Plan Credit Agreement.

We have a secured line of credit that provides for a maximum borrowing of ~~$17.5~~$15.0 million. There were no advances outstanding under this secured line of credit at September 30, ~~2017,~~2021, however, $11.9 million was pledged to secure various letters of credit related to self-insurance products, leaving ~~$5.6~~$3.1 million available for future borrowings as of September 30, ~~2017.~~

~~On March 21, 2017, we entered into a~~ working capital facility with BMO Harris (the “Working Capital Facility”). The Working Capital Facility includes up to $100 million of revolving credit loans to the Company for working capital, capital expenditures and other general corporate purposes. The amount of the borrowings under the Working Capital Facility are subject to borrowing base limitations based on the value of our eligible parts inventory and company vehicles. The Working Capital Facility includes a $20 million letter of credit sublimit. Borrowings under the Working Capital Facility bears interest at rates based on LIBOR or the Base Rate (as such terms are defined in the Working Capital Facility), plus an applicable margin determined based on outstanding borrowing under the Working Capital Facility. In addition, we are required to pay a commitment fee on the amount unused under the Working Capital Facility. The Working Capital Facility expires on the earlier of (i) March 21, 2020 and (ii) the date on which all commitments under the Floor Plan Working Capital Facility shall have terminated, whether as a result of the occurrence of the Commitment Termination Date (as defined in the Floor Plan Working Capital Facility) or otherwise. There were no advances outstanding under the Working Capital Facility as of September 30, 2017.2021.

Our long-term ~~real estate~~ debt,, floor plan financing agreements and the ~~Working Capital Facility~~WF Credit Agreement require us to satisfy various financial ratios such as the ~~debt-to-worth~~leverage ratio, ~~leverage~~the asset coverage ratio and the fixed charge coverage ~~ratio and certain requirements for tangible net worth and GAAP net worth.~~ratio. As of September 30, ~~2017,~~2021, we were in compliance with all debt covenants related to debt secured by ~~real estate,~~ lease and rental units, our floor plan credit agreements and the ~~Working Capital Facility.~~WF Credit Agreement. We do not anticipate any breach of the covenants in the foreseeable future.

We expect to purchase or lease ~~trucks~~commercial vehicles worth approximately $150.0 million to $1~~75.0~~$180.0 million for our leasing operations during ~~2017,~~2021, depending on customer demand, ~~all~~most of which will be financed. We also expect to make capital expenditures for recurring items such as computers, shop tools and equipment and vehicles of approximately ~~$20.0~~$30.0 million to ~~$25.0~~$35.0 million during ~~2017.~~2021.

During the third quarter of 2021, we paid a cash dividend of $10.6 million. Additionally, on October 20, 2021, our Board of Directors declared a cash dividend of $0.19 per share of Class A and Class B Common Stock, to be paid on December 10, 2021, to all shareholders of record as of November 8, 2021. The total dividend disbursement is estimated at approximately $10.6 million. We expect to continue paying cash dividends on a quarterly basis. However, there is no assurance as to future dividends because the declaration and payment of such dividends is subject to the business judgment of our Board of Directors and will depend on historic and projected earnings, capital requirements, covenant compliance and financial conditions and such other factors as our Board of Directors deem relevant.

On ~~November 30, 2016,~~December 8, 2020, we announced that our Board of Directors ~~authorized the~~approved a new stock repurchase program authorizing management to repurchase, from time to time, of up to an aggregate of ~~$40.0~~$100.0 million of our shares of Class A Common Stock ~~and~~and/or Class B Common Stock. In connection with the adoption of the new stock repurchase plan, we terminated the prior stock repurchase plan, which was scheduled to expire on December 31, 2020. Repurchases, if any, will be made at times and in amounts as we deem appropriate and may be made through open market transactions at prevailing market prices, privately negotiated transactions or by other means in accordance with federal securities laws. The actual timing, number and value of repurchases under the stock repurchase program will be determined by management at its discretion and will depend on a number of factors, including market conditions, stock price and other factors, including those related to the ownership requirements of our dealership agreements with Peterbilt. As of September 30, 2021, we had repurchased $23.8 million of our shares of common stock under the current stock repurchase program. The current stock repurchase program expires on ~~November 30, 2017,~~December 31, 2021, and may be suspended or discontinued at any time.~~Through September 30, 2017, we had purchased $30.9 million under this stock repurchase program.~~

We anticipate funding the capital expenditures for the improvement and expansion of existing facilities and recurring expenses through our operating cash flows. We have the ability to fund the construction or purchase of new facilities through our operating cash flows or by financing.

On September 7, 2021, we entered into an Asset Purchase Agreement to acquire substantially all of the assets and assume certain liabilities of Summit Truck Group, LLC, a Texas limited liability company, and certain of its subsidiaries and affiliates (collectively, “Summit”), which assets are currently used in the conduct of commercial vehicle sales, leasing, rental, parts and service business operated by Summit at its dealership facilities located in Arkansas, Kansas, Mississippi, Missouri, Oklahoma, Tennessee and Texas. We estimate that the purchase price, including goodwill, but excluding any real property, will be approximately $223.0 million. At the closing, we anticipate that we will finance approximately $114.0 million of the purchase price. In connection with the transaction, we also anticipate purchasing certain real property of the Seller for approximately $60.0 million pursuant to one or more real property purchase agreements. We do not expect to ultimately own Summit’s dealerships located in Oklahoma or Mississippi.

We have no other material commitments for capital expenditures as of September 30, ~~2017.~~2021. However, we will continue to purchase vehicles for our lease and rental operations and authorize capital expenditures for the improvement or expansion of our existing dealership facilities and construction or purchase of new facilities based on market opportunities.

In June 2012, we entered into a wholesale financing agreement with Ford Motor Credit Company that provides for the financing of, and is collateralized by, our Ford new vehicle inventory. This wholesale financing agreement bears interest at a rate of Prime plus 150 basis points minus certain incentives and rebates; however, the prime rate is defined to be a minimum of 3.75%. As of September 30, 2017, the interest rate on the wholesale financing agreement was 5.25% before considering the applicable incentives. As of September 30, 2017, we had an outstanding balance of approximately $88.8 million under the Ford Motor Credit Company wholesale financing agreement.

On September 14, 2021, we entered into the WF Credit Agreement with the Lenders signatory thereto (the “WF Lenders”) and Wells Fargo Bank, National Association (“WF”), as Administrative Agent (in such capacity, the “WF Agent”). Pursuant to the terms of the WF Credit Agreement, the WF Lenders have agreed to make up to $250.0 million of revolving credit loans for certain of our capital expenditures, including commercial vehicle purchases for our Idealease leasing and rental fleet, and general working capital needs. We expect to use the revolving credit loans available under the WF Credit Agreement primarily for the purpose of purchasing commercial vehicles for our Idealease lease and rental fleet. We may borrow, repay and reborrow loans from time to time until the maturity date. Borrowings under the WF Credit Agreement bear interest per annum, payable on each interest payment date, as defined in the WF Credit Agreement, at (A) the daily simple secured overnight financing rate (“SOFR”) rate plus (i) 1.25% or (ii) 1.5%, depending on our consolidated leverage ratio or (B) on or after the term SOFR transition date, the term SOFR rate plus (i) 1.25% or (ii) 1.5%, depending on our consolidated leverage ratio. The WF Credit Agreement expires on September 14, 2024, although, upon the occurrence and during the continuance of an event of default, the WF Agent has the right to, or upon the request of the required lenders must, terminate the commitments and declare all outstanding principal and interest due and payable. We may terminate the commitments at any time.

On October 1, 2021, we entered into that certain Amended and Restated Inventory Financing and Purchase Money Security Agreement with PLC, a division of PACCAR Financial Corp. (the “PLC Agreement”). Pursuant to the terms of the PLC Agreement, PLC agreed to make up to $300 million of revolving credit loans to finance certain of our capital expenditures, including commercial vehicle purchases and other equipment to be leased or rented through our PacLease franchises. We may borrow, repay and reborrow loans from time to time until the maturity date, provided, however, that the outstanding principal amount on any date shall not exceed the borrowing base. Advances under the PLC Agreement bear interest per annum, payable on the fifth day of the following month, at our option, at either (A) the prime rate, minus 1.55%, provided that the floating rate of interest is subject to a floor of 0%, or (B) a fixed rate, to be determined between us and PLC in each instance of borrowing at a fixed rate. The PLC Agreement expires on October 1, 2025, although either party has the right to terminate the PLC Agreement at any time upon 180 days written notice. If we terminate the PLC Agreement prior to October 1, 2025, then all payments will be deemed to be voluntary prepayments subject to a potential prepayment premium.

Most of our commercial vehicle purchases are made on terms requiring payment to the manufacturer within 15 days or less from the date the commercial vehicles are invoiced from the factory. WeOn September 14, 2021, we entered into the Fifth Amended and Restated Floor Plan Credit Agreement with BMO Harris Bank N.A. and the lenders signatory thereto (the Floor Plan Credit Agreement). Prior to the Floor Plan Credit Agreement, we financed the majority of all new commercial vehicle inventory and the loan value of our used commercial vehicle inventory under the Fourth Amended and Restated Floor Plan Credit Agreement with BMO Harris Bank N.A. and the majority of such financings will continue to occur under the Floor Plan Credit Agreement. The Floor Plan Credit Agreement includes an aggregate loan commitment of ~~$875.0 million.~~$1.0 billion.

On September 30, ~~2017,~~2021, we had approximately ~~$578.8~~$333.7 million outstanding under the Floor Plan Credit Agreement. The average daily outstanding borrowings under the Floor Plan Credit Agreement were ~~$532.8~~$376.8 million during the nine months ended September 30, ~~2017. Periodically, we~~2021.

Navistar Financial Corporation and Peterbilt offer trade terms that provide an ~~interest-free~~interest-free inventory ~~stocking~~ period for certain new commercial vehicles. This interest-free period is generally 15 to 60 days. If the commercial vehicle is not sold within the interest-free period, we then finance the commercial vehicle under the Floor Plan Credit Agreement.

On September 30, ~~201~~7,2021, our backlog of commercial vehicle orders was approximately ~~$1,005.8~~$2,720.2 million, compared to a backlog of commercial vehicle orders of approximately ~~$836.4~~$1,067.3 million on September 30, ~~2016.~~2020. Our backlog is determined quarterly by multiplying the number of new commercial vehicles for each particular type of commercial vehicle ordered by a customer at our Rush Truck Centers by the recent average selling price for that type of commercial vehicle. We include only confirmed orders in our backlog. However, such orders are subject to cancellation. In the event of order cancellation, we have no contractual right to the total revenues reflected in our backlog. The delivery time for a custom-ordered commercial vehicle varies depending on the truck specifications and demand for the particular model ordered. We sell the majority of our new heavy-duty commercial vehicles by customer special order and we sell the majority of our medium- and light-duty commercial vehicles out of inventory. Orders from a number of our major fleet customers are included in our backlog as of September 30, ~~2017~~2021, and we ~~expect to~~are uncertain of when we will fill ~~the majority of~~ our backlog orders ~~during~~due to the ~~next twelve months.~~current supply chain delays.

Our Truck Segment is moderately seasonal. Seasonal effects on new commercial vehicle sales related to the seasonal purchasing patterns of any single customer type are mitigated by the diverse geographic locations of our dealerships and our diverse customer base, including regional and national fleets, local and state governments, corporations and ~~owner operators.~~owner-operators. However, commercial vehicle ~~parts~~Aftermarket Products and ~~service~~Services operations historically have experienced higher sales volumes in the second and third quarters.

Our business is dependent on a number of factors ~~relating to~~including general economic conditions, ~~including~~ fuel prices, interest rate fluctuations, credit availability, ~~economic recessions,~~ environmental and other government regulations and customer business cycles. Unit sales of new commercial vehicles have historically been subject to substantial cyclical variation based on these general economic conditions. According to data published by A.C.T. Research, in recent years, total U.S. retail sales of new Class 8 commercial vehicles have ranged from a low of approximately ~~97,000~~110,000 in ~~2009,~~2010, to a high of approximately ~~291,000~~281,440 in ~~2006.~~2019. Through geographic expansion, concentration on higher margin Aftermarket Products and Services and diversification of our customer base, we have attempted to reduce the negative impact of adverse general economic conditions or cyclical trends affecting the Class 8 commercial vehicle industry on our earnings.

Other than operating leases, we do not have any obligation under any transaction, agreement or other contractual arrangement to which an entity unconsolidated with the Company is a party, that has or is reasonably likely to have a material effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources that is material to investors.

We are subject to ~~a wide range of~~ federal, state and local environmental laws and regulations ~~including those~~ governing the following: discharges into the air and water; the operation and removal of underground and aboveground storage tanks; the use, handling, storage and disposal of hazardous substances, petroleum and other materials; and the investigation and remediation of environmental impacts. As with commercial vehicle dealerships generally, and ~~Aftermarket Products~~vehicle service, parts and ~~Services~~collision center operations in particular, our business involves the generation, use, storage, handling and contracting for recycling or disposal of hazardous materials or wastes and other environmentally sensitive materials. We have incurred, and will continue to incur, capital and operating expenditures and other costs in complying with such laws and regulations.

Our operations involving the use, handling, storage and disposal of hazardous and nonhazardous materials are subject to the requirements of the federal Resource Conservation and Recovery Act, or RCRA, and comparable state statutes. Pursuant to these laws, federal and state environmental agencies have established approved methods for handling, storage, treatment, transportation and disposal of regulated substances ~~and wastes~~ with which we must comply. Our business also involves the operation and use of aboveground and underground storage tanks. These storage tanks are subject to periodic testing, containment, upgrading and removal under RCRA and comparable state statutes. Furthermore, investigation or remediation may be necessary in the event of leaks or other discharges from current or former underground or aboveground storage tanks.

We may also have liability in connection with materials that were sent to ~~third-party~~third‑party recycling, treatment, or disposal facilities under the federal Comprehensive Environmental Response, Compensation and Liability Act, or CERCLA, and comparable state statutes. These statutes impose liability for investigation and remediation of environmental impacts without regard to fault or the legality of the conduct that contributed to the impacts. Responsible parties under these statutes may include the owner or operator of the site where impacts occurred and companies that disposed, or arranged for the disposal, of the hazardous substances released at these sites. These responsible parties also may be liable for damages to natural resources. In addition, it is not uncommon for neighboring landowners and other third parties to file claims for personal injury and property damage allegedly caused by the release of hazardous substances or other materials into the environment.

The federal Clean Water Act and comparable state statutes ~~prohibit discharges into regulated waters without the necessary permits,~~ require containment of potential discharges of oil or hazardous substances, and require preparation of spill contingency plans. Water quality protection programs govern certain discharges from some of our operations. Similarly, the federal Clean Air Act and comparable state statutes regulate emissions of various air emissions through permitting programs and the imposition of standards and other requirements.

The Environmental Protection Agency (“EPA”) and the National Highway Traffic Safety Administration (“NHTSA”), on behalf of the U.S. Department of Transportation, issued ~~final~~ rules ~~on September 15, 2011~~ associated with reducing greenhouse gas (“GHG”) emissions and improving the fuel efficiency of medium and heavy-duty trucks and buses ~~beginning in model year 2014 and being phased in through model year 2018.~~ ~~On June 19, 2015, the EPA and NHTSA proposed further GHG and fuel efficiency standards that would apply to medium and heavy-duty vehicles and buses and would be phased in between~~for model years 2021 through 2027. ~~On August 16, 2016, the EPA and NHTSA issued final rules that largely adopted their June 19, 2015 proposal.~~ We do not believe that ~~the foregoing adopted standards~~these rules will negatively impact our business, however, future legislation or other new regulations that may be adopted to address GHG emissions or fuel efficiency standards may negatively impact our business. ~~Additional~~For example, in June 2020, the California Air Resources Board adopted a final rule that is intended to phase out the sale of diesel-powered commercial vehicles over time by requiring a certain percentage of each manufacturer’s commercial vehicles sold within the state to be “zero-emission vehicles,” or “near-zero emission vehicles,” starting in model year 2024. In addition, in July 2020, a group of fifteen U.S. states and the District of Columbia entered into a joint memorandum of understanding that commits each of them to work together to advance and accelerate the market for electric Class 3 through 8 commercial vehicles. Three of the states that signed are states where we operate new commercial vehicle dealerships: California, Colorado and North Carolina. The signatories to the memorandum all agreed on a goal of ensuring that 100% of new Class 3 through 8 commercial vehicles are zero emission, with an interim target of 30% zero emission by 2030. Attaining these goals would likely require the adoption of new laws and regulations ~~could result in increased compliance costs, additional operating restrictions or changes in demand for our products~~ and ~~services, which could~~we cannot predict at this time whether such laws and regulations would have ~~a material~~an adverse ~~effect~~impact on our ~~business, financial condition and results of operations.~~business.

We do not believe that we ~~do not~~ currently have any material environmental liabilities ~~and~~or that compliance with environmental laws and regulations will ~~not, individually or in the aggregate,~~ have a material adverse effect on our results of operations, financial condition or cash flows. However, soil and groundwater impacts are known to exist at some of our ~~current properties.~~dealerships. Further, environmental laws and regulations are complex and subject to change. In addition, in connection with acquisitions, it is possible that we will assume or become subject to new or unforeseen environmental costs or liabilities, some of which may be material. In connection with our dispositions, or prior dispositions made by companies we acquire, we may retain exposure for environmental costs and liabilities, some of which may be material. Compliance with current or amended, or new or more stringent, laws or regulations, stricter interpretations of existing laws or the future discovery of environmental conditions could require additional expenditures by us, ~~and those expenditures~~which could ~~be material.~~materially adversely affect our results of operations, financial condition or cash flows. In addition, such laws could affect demand for the products that we sell.

Market risk represents the risk of loss that may impact the financial position, results of operations, or cash flows of the Company due to adverse changes in financial market prices, including interest rate risk, and other relevant market rate or price risks.

We are exposed to ~~some~~ market risk through interest rates related to our floor plan financing agreements, the ~~Working Capital Facility, variable rate real estate debt~~WF Credit Agreement, the PLC Agreement and discount rates related to finance sales. The majority of floor plan debt ~~and variable rate real estate debt~~ is based on LIBOR. As of September 30, ~~2017,~~2021, we had floor plan borrowings ~~and variable interest rate real estate debt~~ of approximately ~~$806.1~~$354.3 million. Assuming an increase or decrease in LIBOR of 100 basis points, annual interest expense could correspondingly increase or decrease by approximately ~~$8.1~~$3.5 million.

In the past, we invested in interest-bearing short-term investments consisting of investment-grade auction rate securities classified as available-for-sale. Auctions for investment grade securities held by us have failed. The auction rate securities continue to pay interest in accordance with the terms of the underlying security; however, liquidity will be limited until there is a successful auction or until such time as other markets for these investments develop. As of September 30, 2017, we hold auction rate securities, with underlying tax-exempt municipal bonds that mature in 2030, that have a fair value of $6.4 million. Given the current market conditions in the auction rate securities market, if we determine that the fair value of these securities temporarily decreases by an additional 10%, our equity could correspondingly decrease by approximately $640,000. If it is determined that the fair value of these securities is other-than-temporarily impaired by 10%, we could record a loss on our Consolidated Statements of Income and Comprehensive Income of approximately $640,000.

The Company, under the supervision and with the participation of management, including the Company’s principal executive officer and chief financial officer, evaluated the effectiveness of our disclosure controls and procedures as of the end of the period covered by this report. Based on that evaluation, the principal executive officer and chief financial officer concluded that our disclosure controls and procedures were effective as of September 30, ~~2017~~2021 to ensure that information required to be disclosed in the reports filed or submitted under the Securities Exchange Act of 1934 is (i) recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms, and (ii) is accumulated and communicated to Company management, including the principal executive officer and chief financial officer, as appropriate, to allow timely decisions regarding required disclosure.

There has been no change in our internal control over financial reporting that occurred during the three months ended September 30, ~~2017~~2021 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

From time to time, we are involved in litigation arising out of our operations in the ordinary course of business. We maintain liability insurance, including product liability coverage, in amounts deemed adequate by management. To date, aggregate costs to us for claims, including product liability actions, have not been material. However, an uninsured or partially insured claim, or claim for which indemnification is not available, could have a material adverse effect on our financial condition or results of operations. We believe that there are no claims or litigation pending, the outcome of which could have a material adverse effect on our financial position or results of operations. However, due to the inherent uncertainty of litigation, there can be no assurance that the resolution of any particular claim or proceeding would not have a material adverse effect on our financial condition or results of operations for the fiscal period in which such resolution occurred.

While we attempt to identify, manage and mitigate risks and uncertainties associated with our business to the extent practical under the circumstances, some level of risk and uncertainty will always be present. Item 1A, Part I of our ~~2016~~2020 Annual Report on Form 10-K ~~(the “2016 Annual Report”)~~ describes some of the risks and uncertainties associated with our business that have the potential to materially affect our business, financial condition or results of operations.

~~There has been no material change in our risk factors disclosed in our 2016 Annual Report.~~

WeThe Company did not make any unregistered sales of equity securities during the third quarter of ~~2017.~~2021.

A summary of the ~~Company~~’sCompany’s stock repurchase activity for the third quarter of ~~2017~~2021 is as follows:
