Accounting Policies [Abstract] |
Principles of Consolidation | Principles of Consolidation In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments of a normal recurring nature considered necessary for fair presentation of its financial position as of October 31, 2020 and July 31, 2020, its consolidated statements of income, comprehensive income and stockholders’ equity for the three months ended October 31, 2020 and 2019, and its cash flows for the three months ended October 31, 2020 and 2019. Interim results for the three months ended October 31, 2020 are not necessarily indicative of the results that may be expected for any future period, or for the entire year ending July 31, 2021. These consolidated financial statements have been prepared in accordance with the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted pursuant to such rules and regulations. The interim consolidated financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the fiscal year ended July 31, 2020. Certain prior year amounts have been reclassified to conform to current year presentation. The consolidated financial statements of the Company include the accounts of the parent company and its wholly-owned subsidiaries. Significant intercompany transactions and balances have been eliminated in consolidation.
Use of Estimates | Use of EstimatesThe preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and judgments that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Estimates include, but are not limited to, vehicle pooling costs; income taxes; stock-based compensation; purchase price allocations; and contingencies. Actual results may differ from these estimates.
Revenue Recognition | Revenue Recognition The Company’s primary performance obligation is the auctioning of consigned vehicles through an online auction process. Service revenue and vehicle sales revenue are recognized at the date the vehicles are sold at auction, excluding annual registration fees. Costs to prepare the vehicles for auction, including inbound transportation costs and titling fees, are deferred and recognized at the time of revenue recognition at auction. There were no contract liabilities on the consolidated balance sheets at October 31, 2020 or July 31, 2020. The Company’s disaggregation between service revenues and vehicle sales at the segment level reflects how the nature, timing, amount and uncertainty of its revenues and cash flows are impacted by economic factors. The Company reports sales taxes on relevant transactions on a net basis in the Company’s consolidated results of operations, and therefore does not include sales taxes in revenues or costs. Service revenues The Company’s service revenue consists of auction and auction related sales transaction fees charged for vehicle remarketing services. Within this revenue category, the Company’s primary performance obligation is the auctioning of consigned vehicles through an online auction process. These auction and auction related services may include a combination of vehicle purchasing fees, vehicle listing fees, and vehicle selling fees that can be based on a predetermined percentage of the vehicle sales price, tiered vehicle sales price driven fees, or at a fixed fee based on the sale of each vehicle regardless of the selling price of the vehicle; transportation fees for the cost of transporting the vehicle to or from the Company’s facility; title processing and preparation fees; vehicle storage fees; bidding fees; and vehicle loading fees. These services are not distinct within the context of the contract. Accordingly, revenue for these services is recognized when the single performance obligation is satisfied at the completion of the auction process. The Company does not take ownership of these consigned vehicles, which are stored at the Company’s facilities located throughout the U.S. and at its international locations. These fees are recognized as net revenue (not gross vehicle selling price) at the time of auction in the amount of such fees charged. The Company has a separate performance obligation related to providing access to its online auction platform as the Company charges members an annual registration fee for the right to participate in its online auctions and access the Company’s bidding platform. This fee is recognized ratably over the term of the arrangement, generally one year, as each day of access to the online auction platform represents the best depiction of the transfer of the service. No provision for returns has been established, as all sales are final with no right of return or warranty, although the Company provides for credit loss expense in the case of non-performance by its buyers or sellers.

Vehicle sales Certain vehicles are purchased and remarketed on the Company’s own behalf. The Company has a single performance obligation related to the sale of these vehicles, which is the completion of the online auction process. Vehicle sales revenue is recognized on the auction date. As the Company acts as a principal in vehicle sales transactions, the gross sales price at auction is recorded as revenue.

Contract assets The Company capitalizes certain contract assets related to obtaining a contract, where the amortization period for the related asset is greater than one year. These assets are amortized over the expected life of the customer relationship. Contract assets are classified as current or long-term other assets, based on the timing of when the Company expects to recognize the related revenues and are amortized as an offset to the associated revenues on a straight-line basis. The Company assesses these costs for impairment at least quarterly and as “triggering” events occur that indicate it is more likely than not that an impairment exists. The contract asset costs where the amortization period for the related asset is one year or less are expensed as incurred and recorded within general and administrative expenses in the accompanying statements of income.
Vehicle Pooling Costs | Vehicle Pooling CostsThe Company defers costs that relate directly to the fulfillment of its contracts associated with vehicles consigned to and received by the Company, but not sold as of the end of the period. The Company quantifies the deferred costs using a calculation that includes the number of vehicles at its facilities at the beginning and end of the period, the number of vehicles sold during the period and an allocation of certain yard operation costs of the period. The primary expenses allocated and deferred are inbound transportation costs, titling fees, certain facility costs, labor, and vehicle processing. If the allocation factors change, then yard operation expenses could increase or decrease correspondingly in the future. These costs are expensed into yard operations expenses as vehicles are sold in subsequent periods on an average cost basis.
Foreign Currency Translation | Foreign Currency Translation The Company records foreign currency translation adjustments from the process of translating the functional currency of the financial statements of its foreign subsidiaries into the U.S. dollar reporting currency. The British pound, Canadian dollar, Brazilian real, European Union euro, U.A.E. dirham, Omani rial, and Bahraini dinar are the functional currencies of the Company’s foreign subsidiaries as they are the primary currencies within the economic environment in which each subsidiary operates. The original equity investment in the respective subsidiaries is translated at historical rates. Assets and liabilities of the respective subsidiary’s operations are translated into U.S. dollars at period-end exchange rates, and revenues and expenses are translated into U.S. dollars at average exchange rates in effect during each reporting period. Adjustments resulting from the translation of each subsidiary’s financial statements are reported in other comprehensive income.
Fair Value of Financial Instruments | Fair Value of Financial Instruments The Company records its financial assets and liabilities at fair value in accordance with the framework for measuring fair value in U.S. GAAP. In accordance with Accounting Standards Codification (“ASC”) 820, Fair Value Measurements and Disclosures, the Company considers fair value as an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants under current market conditions. This framework establishes a fair value hierarchy that prioritizes the inputs used to measure fair value: Level I Observable inputs that reflect unadjusted quoted prices for identical assets or liabilities traded in active markets. Level II Inputs other than quoted prices included within Level I that are observable for the asset or liability, either directly or indirectly. Level III Inputs that are generally unobservable. These inputs may be used with internally developed methodologies that result in management’s best estimate. The amounts recorded for financial instruments in the Company’s consolidated financial statements, which included cash, restricted cash, accounts receivable, accounts payable, accrued liabilities, and amounts outstanding under the Revolving Loan Facility approximated their fair values as of October 31, 2020 and July 31, 2020, due to the short-term nature of those instruments and are classified within Level II of the fair value hierarchy. Cash equivalents are classified within Level II of the fair value hierarchy because they are valued using quoted market prices of the underlying investments. See Note 6 – Long-Term Debt and Note 7 – Fair Value Measures.
Cash, Cash Equivalents, and Restricted Cash | Cash, Cash Equivalents, and Restricted CashThe Company considers all highly liquid investments purchased with original maturities of three months or less at the time of purchase to be cash equivalents. Cash, cash equivalents, and restricted cash include cash held in checking, domestic certificates of deposit, U.S. Treasury Bills, and money market accounts. The Company periodically invests its excess cash in money market funds and U.S. Treasury Bills. The Company’s cash, cash equivalents, and restricted cash are placed with high credit quality financial institutions.
Segments and Other Geographic Reporting | The Company’s U.S. and International regions are considered two separate operating segments and are disclosed as two reportable segments. The segments represent geographic areas and reflect how the chief operating decision maker allocates resources and measures results, including total revenues and operating income.
Capitalized Software Costs | Capitalized Software CostsThe Company capitalizes system development costs and website development costs related to the enterprise computing services during the application development stage. Costs related to preliminary project activities and post implementation activities are expensed as incurred. Internal-use software is amortized on a straight-line basis over its estimated useful life, generally three to seven years. The Company evaluates the useful lives of these assets on an annual basis and tests for impairment whenever events or changes in circumstances occur that impact the recoverability of these assets.
Recent Accounting Pronouncements | Pending In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes. ASU 2019-12 eliminates certain exceptions related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. It also clarifies and simplifies other aspects of the accounting for income taxes. This guidance is effective for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years. The Company’s adoption of ASU 2019-12 is not expected to have a material impact on the Company’s consolidated results of operations and financial position. Adopted In January 2017, the FASB issued ASU 2017-04, Intangibles-Goodwill and Other (Topic 350). ASU 2017-04 amends the requirement that entities compare the implied fair value of goodwill with its carrying amount as part of step 2 of the goodwill impairment test. As a result, entities should perform their annual or interim goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount and recognize an impairment if the carrying amount exceeds the reporting unit’s fair value. ASU 2017-04 was effective for fiscal years beginning after December 15, 2019. The Company’s adoption of ASU 2017-04 did not have a material impact on the Company’s consolidated results of operations and financial position. In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326). ASU 2016-13 requires entities to use a current lifetime expected credit loss methodology to measure impairments of certain financial assets. Using this methodology will result in earlier recognition of losses than the previous incurred loss approach, which required waiting to recognize a loss until it was probable of having been incurred. There are other provisions within the standard that affect how impairments of other financial assets may be recorded and presented, and that expand disclosures. This pronouncement was effective for fiscal years beginning after December 15, 2019, and was required to be applied on a modified retrospective basis. The Company’s adoption of ASU 2016-13 did not have a material impact on the Company’s consolidated results of operations, financial position, and related disclosures.
