Summary of Significant Accounting Policies (Policies) | 12 Months Ended
--- | ---
Jul. 31, 2015
Accounting Policies [Abstract] |
Consolidation, Subsidiaries or Other Investments, Consolidated Entities, Policy [Policy Text Block] | The consolidated financial statements of the Company include the accounts of the parent company and its wholly-owned subsidiaries, including its foreign wholly-owned subsidiaries. Significant intercompany transactions and balances have been eliminated in consolidation.
Use of Estimates | Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles (GAAP) requires management to make estimates and assumptions 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; self-insured reserves; allowance for doubtful accounts; income taxes; revenue recognition; stock-based payment compensation; purchase price allocations; long-lived asset and goodwill impairment calculations and contingencies. Actual results could differ from these estimates.
Revenue Recognition | Revenue Recognition The Company provides a portfolio of services to its sellers and buyers that facilitate the sale and delivery of a vehicle from seller to buyer. These services include the ability to use the Company’s Internet sales technology and vehicle delivery, loading, title processing, preparation and storage. The Company evaluates multiple-element arrangements relative to its member and seller agreements. The services provided to the seller of a vehicle involve disposing of a vehicle on the seller’s behalf and, under most of the Company’s current North American contracts, collecting the proceeds from the member. The Company applies Accounting Standard Update 2009-13, Revenue Recognition (Topic 605): Multiple-Deliverable Revenue Arrangements (ASU 2009-13) for revenue recognition. Pre-sale services, including towing, title processing, preparation and storage, as well as sale fees and other enhancement services meet the criteria for separate units of accounting. Revenue associated with each service is recognized upon completion of the respective service, net of applicable rebates or allowances. For certain sellers who are charged a proportionate fee based on high bid of the vehicle, the revenue associated with the pre-sale services is recognized upon completion of the sale when the total arrangement is fixed and determinable. The estimated selling price of each service is determined based on management’s best estimate and allotted based on the relative selling price method. Vehicle sales, where vehicles are purchased and remarketed on the Company’s own behalf, are recognized on the sale date, which is typically the point of high bid acceptance. Upon high bid acceptance, a legal binding contract is formed with the member, and the gross sales price is recorded as revenue. The Company also provides a number of services to the buyer of the vehicle, charging a separate fee for each service. Each of these services has been assessed to determine whether the requirements have been met to separate them into units of accounting within a multiple-element arrangement. The Company has concluded that the sale and the post-sale services are separate units of accounting. The fees for sale services are recognized upon completion of the sale, and the fees for the post-sale services are recognized upon successful completion of those services using the relative selling price method. The Company also charges members an annual registration fee for the right to participate in its vehicle sales program, which is recognized ratably over the term of the arrangement, and relist and late-payment fees, which are recognized upon receipt of payment by the member. No provision for returns has been established, as all sales are final with no right of return, although the Company provides for bad debt expense in the case of non-performance by its members or sellers. The Company allocates arrangement consideration based upon management’s best estimate of the selling price of the separate units of accounting contained within arrangements including multiple deliverables. Significant inputs in the Company’s estimates of the selling price of separate units of accounting include market and pricing trends, pricing customization and practices, and profit objectives for the services.
Vehicle Pooling Costs | Vehicle Pooling Costs The Company defers in vehicle pooling costs certain yard operation expenses 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 certain facility costs, labor, transportation, and vehicle processing. If the allocation factors change, then yard operation expenses could increase or decrease correspondingly in the future. These costs are expensed as vehicles are sold in subsequent periods on an average cost basis. Given the fixed cost nature of the Company’s business, there are no direct correlations for increases in expenses or units processed on vehicle pooling costs. The Company applies the provisions of accounting guidance for subsequent measurement of inventory to our vehicle pooling costs. The provision requires that items such as idle facility expenses, double freight and rehandling costs be recognized as current period charges regardless of whether they meet the criteria of “abnormal” as provided in the guidance. In addition, the guidance requires that the allocation of fixed production overhead to the costs of conversion be based on the normal capacity of production facilities. In early November 2012, Hurricane Sandy hit the northeastern coast of the United States. As a result of the extensive flooding that it caused, the Company expended additional costs for (i) temporary storage facilities; (ii) premiums for subhaulers as they were reassigned from other regions; and (iii) labor costs incurred for overtime, travel and lodging due to the reassignment of employees to the affected region. These costs, which are characterized as “abnormal” under ASC 330, Inventory, were expensed as incurred and not included in inventory. At July 31, 2013, the incremental salvage vehicles received as a result of Hurricane Sandy were sold.
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 Canadian dollar, British pound, U.A.E. dirham, Bahraini dinar, Omani rial, Brazilian real, and Euro 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 ASC 820, Fair Value Measurements and Disclosures, as amended by Accounting Standards Update 2011-04, 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. Interest rate hedges are valued at exit prices obtained from the counter-party.
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, accounts receivable, accounts payable and accrued liabilities approximated their fair values as of July 31, 2015 and 2014, 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 8 — Long-Term Debt for additional fair value disclosures.
Derivatives and Hedging | Derivatives and Hedging The Company has entered into two interest rate swaps to eliminate interest rate risk on the Company’s variable interest rate debt, and the swaps are designated as effective cash flow hedges under ASC 815, Derivatives and Hedging. See Note 9 — Derivatives and Hedging. Each quarter, the Company measures hedge effectiveness using the “hypothetical derivative method” and records in earnings any hedge ineffectiveness with the effective portion of the change in fair value recorded in other comprehensive income or loss.
Cost of Vehicle Sales | Cost of Vehicle Sales Cost of vehicle sales includes the purchase price of vehicles sold for the Company’s own account.
Yard Operations | Yard Operations Yard operations consists primarily of operating personnel (which includes yard management, clerical and yard employees), rent, contract vehicle towing, insurance, fuel and equipment maintenance and repair. The Company recognizes the costs of pre-sale services, including towing, title processing, and preparation and storage within yard operation expenses at the time the related services are provided.
General and Administrative Expenses | General and Administrative Expenses General and administrative expenses consist primarily of executive, accounting and data processing, sales personnel, professional services, system maintenance and enhancements and marketing expenses.
Advertising | Advertising All advertising costs are expensed as incurred and are included in general and administrative expenses on the consolidated statements of income.
Other (Expense) Income | Other (Expense) Income Other (expense) income consists primarily of interest expense, interest income, gains and losses from the disposal of fixed assets, rental income, and earnings from unconsolidated affiliates.
Net Income Per Share | Net Income Per Share Basic net income per share amounts were computed by dividing consolidated net income by the weighted average number of common shares outstanding during the period. Diluted net income per share amounts were computed by dividing consolidated net income by the weighted average number of common shares outstanding plus dilutive potential common shares calculated for stock options outstanding during the period using the treasury stock method.
Cash and Cash Equivalents | Cash and Cash Equivalents The 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 and cash equivalents include cash held in checking, domestic certificates of deposit, and money market accounts. The Company periodically invests its excess cash in money market funds and U.S. Treasury Bills. The Company’s cash and cash equivalents are placed with high credit quality financial institutions.
Bank Overdraft | Bank Overdraft As a result of maintaining a consolidated cash management system, the Company utilizes controlled disbursement bank accounts. These accounts are funded as checks are presented for payment, not when checks are issued. The resulting bank overdraft position was included in current liabilities as of July 31, 2013.
Inventory | Inventory Inventories of purchased vehicles are stated at the lower of cost or estimated realizable value. Cost includes the Company’s cost of acquiring ownership of the vehicle. The cost of vehicles sold is charged to cost of vehicle sales as sold on a specific identification basis.
Accounts Receivable | Accounts Receivable Accounts receivable, which consist primarily of advance charges due from insurance companies and the gross sales price of the vehicle due from members, are recorded when billed, advanced or accrued and represent claims against third parties that will be settled in cash.
Allowance For Doubtful Accounts | Allowance for Doubtful Accounts The Company maintains an allowance for doubtful accounts in order to provide for estimated losses resulting from disputed amounts billed to sellers or members and the inability of sellers or members to make required payments. If billing disputes exceed expectations and/or if the financial condition of sellers or members were to deteriorate, additional allowances may be required. The allowance is calculated by considering both seller and member accounts receivables written off during the previous twelve-month period as a percentage of the total accounts receivable balance.
Concentration of Credit Risk | Concentration of Credit Risk Financial instruments, which subject the Company to potential credit risk, consist of its cash and cash equivalents, short-term investments and accounts receivable. The Company adheres to its investment policy when placing investments. The investment policy has established guidelines to limit the Company’s exposure to credit risk by placing investments with high credit quality financial institutions, diversifying its investment portfolio, limiting investments in any one issuer or pooled fund and placing investments with maturities that maintain safety and liquidity. The Company places its cash and cash equivalents with high credit quality financial institutions. Deposits with these financial institutions may exceed the amount of insurance provided; however, these deposits typically are redeemable upon demand and, therefore, the Company believes that the financial risks associated with these financial instruments are minimal. The Company performs ongoing credit evaluations of its customers, and generally does not require collateral on its accounts receivable. The Company estimates its allowances for doubtful accounts based on historical collection trends, the age of outstanding receivables and existing economic conditions. If events or changes in circumstances indicate that specific receivable balances may be impaired, further consideration is given to the collectability of those balances and the allowance is adjusted accordingly. Past-due account balances are written off when the Company’s internal collection efforts have been unsuccessful in collecting the amounts due. The Company does not have off-balance sheet credit exposure related to its customers and to date, the Company has not experienced significant credit-related losses.
Property and Equipment | Property and Equipment Property and equipment is stated at cost, less accumulated depreciation and amortization. Leasehold improvements are amortized on a straight-line basis over the shorter of the lease term or the estimated useful lives of the respective improvements, which is between five and ten years. Significant improvements which substantially extend the useful lives of assets are capitalized. Expenditures for maintenance and repairs are charged to expense as incurred. Depreciation and amortization are computed on a straight-line basis over the estimated useful lives: three to five years for internally developed or purchased software; three to seven years for transportation and other equipment; three to ten years for office furniture and equipment; and 5 to 40 years or the lease term, whichever is shorter, for buildings and improvements. Amortization of equipment under capital leases is included in depreciation expense.
Long-Lived Asset Valuation | Long-Lived Asset Valuation The Company evaluates long-lived assets, including property and equipment, for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. In accordance with ASC 360, Property, Plant, and Equipment, a long-lived asset is initially measured at the lower of its carrying amount or fair value. An impairment loss is recognized when the estimated undiscounted future cash flows expected to be generated from the use of the asset are less than the carrying amount of the asset. The impairment loss is then calculated by comparing the carrying amount with its fair value, which is usually estimated using discounted cash flows expected to be generated from the use of the asset.
Goodwill and Other Identifiable Intangible Assets | Goodwill and Other Identifiable Intangible Assets In accordance with ASC 350-30-35, Intangibles—Goodwill and Other, goodwill is not amortized but is tested for potential impairment, at a minimum on an annual basis, or when indications of potential impairment exist. The Company performed its annual impairment test for goodwill during the fourth quarter of the year ended July 31, 2015, utilizing a market value and discounted cash flow approach. The impairment test for identifiable intangible assets not subject to amortization is also performed annually or when impairment indicators exist. The impairment test consists of a comparison of the fair value of the intangible asset with its carrying amount. Identifiable intangible assets that are subject to amortization are evaluated for impairment using a process similar to that used to evaluate other long-lived assets.
Capitalized Software Costs | Capitalized Software Costs The 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 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. Total gross capitalized software as of July 31, 2015 and 2014 was $65.1 million and $61.7 million, respectively. Accumulated amortization expense related to software as of July 31, 2015 and 2014 totaled $42.6 million and $38.6 million, respectively. The Company reassessed its strategy of utilizing a third-party enterprise operating system to address its international expansion needs based on the projected cost to complete, deployment risk and certain other factors. The Company decided to cease development of this software and address its international technology needs through an internally developed proprietary solution.
Retained Insurance Liabilities | Retained Insurance Liabilities The Company is partially self-insured for certain losses related to medical, general liability, workers’ compensation and auto liability. The Company’s insurance policies are subject to a $250,000 deductible per claim, with the exception of its medical policy which has a $225,000 stop loss per claim and a stop loss limiting total exposure to 120% of expected claims. In addition, each of the Company’s policies contains an aggregate stop loss which limits its ultimate exposure. The Company’s liability represents an estimate of the ultimate cost of claims incurred as of the balance sheet date. The estimated liability is not discounted and is established based upon analysis of historical data and actuarial estimates. The primary estimates used in the actuarial analysis include total payroll and revenue. The Company’s estimates have not materially fluctuated from actual results. While the Company believes these estimates are reasonable based on the information currently available, if actual trends, including the severity of claims and medical cost inflation, differ from the Company’s estimates, the Company’s consolidated results of operations, financial position or cash flows could be impacted. The process of determining the Company’s insurance reserves requires estimates with various assumptions, each of which can positively or negatively impact those balances.
Stock-Based Payment Compensation | Stock-Based Payment Compensation The Company accounts for stock-based awards to employees and non-employees using the fair value method as required by ASC 718, Compensation—Stock Compensation (ASC 718), which requires the measurement and recognition of compensation expense for all stock-based payment awards made to employees, consultants and directors based on estimated fair value. ASC 718 requires companies to estimate the fair value of stock-based payment awards on the measurement date using an option-pricing model. The value of the portion of the award that is ultimately expected to vest is recognized in expense over the requisite service periods. ASC 718 requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Option valuation models require the input of highly subjective assumptions including the expected stock price volatility. Because the Company’s employee stock options have characteristics significantly different from those of traded options and because changes in the input assumptions can materially affect their fair value estimate, it is the Company’s opinion that the existing models do not necessarily provide a reliable single measure of the fair value of the employee stock options. The fair value of each option was estimated on the measurement date using the Black-Scholes Merton (BSM) option-pricing model utilizing the following assumptions:
| July 31,
| 2015 |  | 2014 |  | 2013
Expected life (in years) | 5.3 – 7.2 |  |  | 5.1 – 7.1 |  |  | 5.2 – 6.9 |
Risk-free interest rate | 1.58 – 2.26 |  |  | 1.55 – 2.3 |  |  | 0.61 – 1.5 |
Estimated volatility | 22 – 28 |  |  | 20 – 25 |  |  | 24 – 26 |
Expected dividends | — | % |  | — | % |  | — | %
Weighted average fair value at measurement date | $ | 10.18 |  |  | $ | 11.10 |  |  | $ | 7.87 |
Expected life—The Company’s expected life represents the period that the Company’s stock-based payment awards are expected to be outstanding and was determined based on historical experience of similar awards, giving consideration to the contractual terms of the stock-based payment awards, vesting schedules and expectations of future employee behavior as influenced by changes to the terms of its stock-based payment awards. Estimated volatility—The Company uses the trading history of its common stock in determining an estimated volatility factor when using the BSM option-pricing model to determine the fair value of options granted. Expected dividend—The Company has not declared dividends. Therefore, the Company uses a zero value for the expected dividend value factor when using the BSM option-pricing model to determine the fair value of options granted. Risk-free interest rate—The Company bases the risk-free interest rate used in the BSM option-pricing model on the implied yield currently available on U.S. Treasury zero-coupon issues with the same or substantially equivalent expected life. Estimated forfeitures—When estimating forfeitures, the Company considers voluntary and involuntary termination behavior as well as analysis of actual option forfeitures. Net cash proceeds from the exercise of stock options were $3.6 million, $10.4 million and $21.4 million for the years ended July 31, 2015, 2014 and 2013, respectively. The Company realized an income tax benefit of $3.0 million, $2.3 million and $6.1 million from stock option exercises during the years ended July 31, 2015, 2014 and 2013, respectively. In accordance with ASC 718, the Company presents excess tax benefits from disqualifying dispositions of the exercise of incentive stock options, vested prior to August 1, 2005, if any, as financing cash flows rather than operating cash flows.
Comprehensive Income | Comprehensive Income Comprehensive income includes all changes in stockholders’ equity during a period from non-stockholder sources. For the years ended July 31, 2015, 2014 and 2013, accumulated other comprehensive income (loss) was the effect of foreign currency translation adjustments and the effective portion of the interest rate swaps’ change in fair value. Deferred taxes are not provided on cumulative translation adjustments where the Company expects earnings of a foreign subsidiary to be indefinitely reinvested.
Reclassification | Reclassifications Certain reclassifications have been made to prior years' consolidated financial statements to conform to the classifications used in fiscal 2015.
Recently Issued Accounting Standards | Recently Issued Accounting Standards In April 2015, the FASB issued ASU 2015-03, Interest - Imputation of Interest (Subtopic 835-30), which requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by the amendments in this ASU. The amendments are effective for financial statements issued for annual and interim periods beginning after December 15, 2015. The amendments are to be applied on a retrospective basis, wherein the balance sheet of each individual period presented is adjusted to reflect the period-specific effects of applying the new guidance. The Company’s adoption of ASU 2015-03 will not have a material impact on the Company’s consolidated results of operations and financial position. In February 2015, the FASB issued ASU 2015-02, Consolidation (Topic 810), which is intended to improve targeted areas of consolidation guidance for legal entities such as limited partnerships, limited liability corporations, and securitization structures (collateralized debt obligations, collateralized loan obligations, and mortgage-backed security transactions). The ASU focuses on the consolidation evaluation for reporting organizations that are required to evaluate whether they should consolidate certain legal entities. In addition to reducing the number of consolidation models from four to two, the new standard simplifies the FASB Accounting Standards Codification and improves current U.S. GAAP by placing more emphasis on risk of loss when determining a controlling financial interest, reducing the frequency of the application of related-party guidance when determining a controlling financial interest in a variable interest entity (“VIE”), and changing consolidation conclusions for companies in several industries that typically make use of limited partnerships or VIEs. The ASU will be effective for annual and interim periods beginning after December 15, 2015. The Company’s adoption of ASU 2015-02 will not have a material impact on the Company’s consolidated results of operations and financial position. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), which supersedes the revenue recognition requirements in ASC 605, Revenue Recognition. ASU 2014-09 is based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. ASU 2014-09 is effective for annual and interim periods beginning after December 15, 2016, . On July 9, 2015, the FASB issued a proposed ASU to defer the effective date for one year for annual and interim periods beginning after December 15, 2017. ASU 2014-09 allows adoption with either retrospective application to each period presented, or retrospective application with the cumulative effect recognized as of the date of initial application. The Company has not determined the potential effects of implementing ASU 2014-09 on the consolidated financial statements.
Acquisitions | Acquisitions The Company recognizes and measures identifiable assets acquired and liabilities assumed in acquired entities in accordance with ASC 805, Business Combinations. The accounting for acquisitions involves significant judgments and estimates, including the fair value of certain forms of consideration, the fair value of acquired intangible assets, which involve projections of future revenues, cash flows and terminal value, which are then either discounted at an estimated discount rate or measured at an estimated royalty rate, and the fair value of other acquired assets and assumed liabilities, including potential contingencies and the useful lives of the assets. The projections are developed using internal forecasts, available industry and market data and estimates of long-term growth rates of the Company. Historical experience is additionally utilized, in which historical or current costs have approximated fair value for certain assets acquired.
Segments and Other Geographic Reporting | Segments and Other Geographic Reporting The Company’s North American and U.K. regions are considered two separate operating segments, which have been aggregated into one reportable segment because they share similar economic characteristics.
