Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	1 – Principles of Consolidation and Basis of Presentation 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 for the year ended December 31, 2018. 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.

Notes to Financial Statements
Other Assets Disclosure [Text Block]	2 – Other Assets ERP Platform The total capitalized costs of the Company’s SAP enterprise resource planning software platform (“ERP Platform”) of $10.3 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 $0.5 million for the three months ended March 31, 2019 and $11.1 million for the three months ended March 31, 2018 ( see below). The Company estimates that amortization expense relating to the ERP Platform will be approximately $ 1.9 million for each of the next five years. In the first quarter of 2018, as part of an assessment that involved a technical feasibility study of the then current ERP Platform, the Company determined that a majority of the components of this ERP Platform would require replacement earlier than originally anticipated; in prior disclosures, the Company had referred to the ERP Platform separately as the SAP enterprise software and SAP dealership management system. In accordance with Accounting Standards Codification (“ASC”) Topic 350 - 40, in the first quarter of 2018, the Company adjusted the useful life of these components that were replaced so that the respective net book values of the components were fully amortized upon replacement in May 2018. The Company amortized the remaining net book value of the components that were replaced on a straight-line basis in February 2018 through May 2018. The Company recognized $19.9 million of amortization expense in 2018 related to the components of the ERP Platform that were replaced. The ERP Platform asset and related amortization are reflected in the Truck Segment. Franchise Rights The Company’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 March 31, 2019 and December 31, 2018, and is included in Other Assets on the accompanying 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 to geographic region, the Company has determined that evaluating and including all locations acquired in the geographic region is the appropriate level for 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. 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. No impairment write down was required in 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. Equity Method Investment and Call Option 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 of RTC Canada until the close of business on February 25, 2024. On March 31, 2019, the fair market value of the Company’s call option was $3.6 million and is reported in Other Assets on the Consolidated Balance Sheet. The determination of fair market value is based upon a number of assumptions, including the estimated fair value of the equity of RTC Canada and the risk free interest rate. As of March 31, 2019, the Company’s investment in RTC Canada is $19.4 million.

Notes to Financial Statements
Commitments and Contingencies Disclosure [Text Block]	3 – Commitments and Contingencies 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 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 the Company’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.

Notes to Financial Statements

Fair Value Disclosures [Text Block]

– Financial Instruments and Fair Value

The Company has various financial instruments that it must measure 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 on 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

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

Level

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

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

March 31, 2019,

and

December 31, 2018.

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, 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 current credit standing and has categorized such debt within Level

of the hierarchy framework. The carrying amount 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.

Long-Lived Assets

During the

first

quarter of

2016,

the Company instituted plans to consolidate its dealership network. In

2016,

the Company recorded an impairment charge related to the value of the real estate in the affected locations and a write-down of certain excess real estate. The fair value measurements for the Company’s long-lived assets are based on Level

inputs. Fair values of the value of the real estate were determined based on evaluations by a

third

-party real estate broker that utilized its knowledge and historical experience in real estate markets and transactions. As of

March 31, 2019,

the remaining real estate associated with the restructuring activities is included in assets held for sale on the Consolidated Balance Sheets.

Segment Reporting Disclosure [Text Block]

– Segment Information

The Company currently has

one

reportable business segment - the Truck Segment. The Truck Segment includes the Company’s operation of a nationwide network of commercial vehicle dealerships that provide an integrated

one

-stop source for the commercial vehicle needs of its customers, including retail sales of new and used commercial vehicles; aftermarket parts, service and 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 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

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 revenues, segment income or loss from continuing operations and segment assets for the periods ended

Income Tax Disclosure [Text Block]	8 – Income Taxes The Company had unrecognized income tax benefits totaling $ 2.4 million as a component of accrued liabilities at March 31, 2019 and December 31, 2018, 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. The Company had approximately $ 139,000 accrued for the payment of interest at March 31, 2019 and December 31, 2018. No 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 March 31, 2019, the tax years ended December 31, 2015 through 2018 remain subject to audit by federal tax authorities and the tax years ended December 31, 2014 through 2018 remain subject to audit by state tax authorities. The Company adopted ASU 2016 - 09 on January 1, 2017, which 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. In the first quarter of 2019, the Company recorded $76,000 of tax expense related to an excess tax deficiency with respect to equity compensation. In the first quarter of 2018, the Company recorded $22,000 of tax expense related to an excess tax deficiency with respect to equity compensation.

Revenue

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, 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.

February 2016,

“

Leases (

“

Topic

842

”

” which was 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. The standard requires lessees to record assets and liabilities on the balance sheet for all leases with terms longer than

twelve

months. Leases are classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement.

The Company determines whether the leases should be classified as an operating lease or finance lease. A lease is classified as a finance lease if any of the following conditions exist on the date of lease commencement:

	●	The lease transfers ownership of the underlying asset to the lessee by the end of the lease term.
	●	The lease provides the lessee an option to purchase the underlying asset, and that option is reasonably certain to be exercised.
	●	The lease term is for the major part of the remaining economic life of the underlying asset.
	●	The present value of the lease payments equals or exceeds substantially all of the fair value of the underlying asset.
	●	The underlying asset is of such a specialized nature that only the lessee can use it without major modifications. The lessor expects to have no alternative use for the leased asset at the end of the lease.

The Company adopted Topic

842

January 1, 2019.

The Company applied a modified retrospective transition approach for all leases existing at, or entered into after,

January 1, 2019.

The Consolidated Financial Statements for the quarter ended

March 31, 2019

are presented under the new standard, while the comparative quarter presented is

not

adjusted and continues to be reported in accordance with the Company’s historical accounting policy. The Company applied the practical expedients permitted within Topic

842,

which among other things, allows it to retain its existing assessment of whether an arrangement is, or contains, a lease and whether such lease is classified as an operating or finance lease. The Company made an accounting policy election that keeps leases with an initial term of

twelve

months or less off of the balance sheet and results in recognizing those lease payments in the Consolidated Statements of Income and Comprehensive Income on a straight-line basis over the lease term.

The Company leases commercial vehicles and real estate under finance and operating leases. The Company determines whether an arrangement is a lease at its inception. For leases with terms greater than

twelve

months, the Company records the related asset and obligation at the present value of lease payments over the term. Many of the Company’s leases include renewal options and/or termination options that are factored into its determination of lease payments when appropriate. The Company has elected

not

to account for lease and nonlease components as a single combined lease component as lessee.

When available, the Company uses the rate implicit in the lease to discount lease payments to present value; however, most of its leases do

not

provide a readily determinable implicit rate. Therefore, the Company must estimate its incremental borrowing rate to discount the lease payments based on information available at lease commencement.

ase

of Vehicles

as Lessee

The Company leases commercial vehicles as the lessee under finance leases and operating leases. The lease terms vary from

one

month to

ten

years. Commercial vehicle finance leases continue to be reported on the Consolidated Balance Sheet, while operating leases were added to the Consolidated Balance Sheet in

2019

with the adoption of Topic

842.

These vehicles are then subleased or rented by the Company to customers under various agreements. For the

three

months ended

March 31, 2019,

the Company received sublease income of

$6.0

million under non-cancelable subleases.

The Company usually guarantees the residual value of vehicles under operating lease and finance lease arrangements. At

March 31, 2019,

the Company guaranteed commercial vehicle residual values of approximately

$39.0

million under operating lease and finance lease arrangements.

se of

Facilities

as Lessee

The Company’s facility leases are classified as operating leases and primarily reflect its use of dealership facilities and office space. The lease terms vary from

one

year to

years, some of which include options to extend the lease term, and some of which include options to terminate the lease within

one

year. The Company considers these options in determining the lease term used to establish its right-of-use assets and lease liabilities.

Lease

of Vehicles

as Lessor

The Company leases vehicles that the Company owns to customers primarily over periods of

one

ten

years. The Company applied the practical expedient permitted within Topic

842

that allows it

not

to separate lease and nonlease components. Nonlease components typically consist of maintenance and licensing for the commercial vehicle. Some leases contain an option for the lessee to purchase the commercial vehicle.

Our policy is to depreciate our lease and rental fleet using a straight line method over each customer’s contractual lease term. The lease unit is depreciated to a residual value that approximates fair value at the expiration of the lease term. This policy results in 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.

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 at

March 31, 2019

in the amount of

$5.3

million is reflected in Other Assets on the Consolidated Balance Sheet.
