Accounting Policies [Abstract]
Summary of Significant Accounting Policies	1 — Summary of Significant Accounting Policies Basis of Presentation and Description of Business Copart, Inc. was incorporated under the laws of the State of California in 1982. In January 2012, the Company changed the state in which it is incorporated (the “Reincorporation”), and is now incorporated under the laws of the State of Delaware. All references to “we,” “us,” “our,” or “the Company” herein refer to the California corporation prior to the date of the Reincorporation, and to the Delaware corporation on and after the date of the Reincorporation. 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. The Company provides vehicle sellers with a full range of services to process and sell vehicles over the Internet through the Company’s Virtual Bidding Third Generation (VB3) Internet auction-style sales technology. Sellers are primarily insurance companies but also include banks and financial institutions, charities, car dealerships, fleet operators, vehicle rental companies, as well as cars sourced from the general public. The Company sells principally to licensed vehicle dismantlers, rebuilders, repair licensees, used vehicle dealers and exporters; however, at certain locations, the Company sells directly to the general public. The majority of vehicles sold on behalf of insurance companies are either damaged vehicles deemed a total loss or not economically repairable by the insurance companies or are recovered stolen vehicles for which an insurance settlement with the vehicle owner has already been made. The Company offers vehicle sellers a full range of services that expedite each stage of the vehicle sales process, minimize administrative and processing costs and maximize the ultimate sales price. In the United States (U.S.), Canada, Brazil, the United Arab Emirates (U.A.E.), Oman, Bahrain, Ireland, Spain and India, the Company sells vehicles primarily as an agent and derives revenue primarily from fees paid by vehicle sellers and vehicle buyers as well as related fees for services, such as towing and storage. In the United Kingdom (U.K.), the Company operates both as an agent and on a principal basis, purchasing the salvage vehicle outright from the insurance company and reselling the vehicle for its own account. In Germany and Spain, the Company derives revenue from sales listing fees for listing vehicles on behalf of insurance companies. 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 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 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 the 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 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 its 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. 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, Indian rupee, 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. The cumulative effects of foreign currency exchange rate fluctuations were as follows (in thousands): Cumulative loss on foreign currency translation as of July 31, 2014 $ (18,992 ) Loss on foreign currency translation (49,518 ) Cumulative loss on foreign currency translation as of July 31, 2015 $ (68,510 ) Loss on foreign currency translation (40,684 ) Cumulative loss on foreign currency translation as of July 31, 2016 $ (109,194 ) 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, accrued liabilities and Revolving Loan Facility approximated their fair values as of July 31, 2016 and 2015 , 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 , Note 10 – Fair Value Measures , and Note 10 – Fair Value Measures . 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 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 consist primarily of executive, accounting and data processing, sales personnel, professional services, system maintenance and enhancements and marketing expenses. Advertising All advertising costs are expensed as incurred and are included in general and administrative expenses on the consolidated statements of income. Advertising expenses were $6.8 million , $4.9 million , and $5.0 million for the years ended July 31, 2016 , 2015 and 2014 , respectively. Other (Expense) Income Other (expense) income consists primarily of interest expense, interest income, gains and losses from the disposal of fixed assets, rental income, earnings from unconsolidated affiliates, and currency related gains and losses. 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. During the year ended July 31, 2016 , the Company early adopted ASU No. 2016-09, Improvements to Employee Share-Based Payment Accounting , which caused an impact on dilutive potential common shares outstanding, as the Company excluded the excess tax benefits and deficiencies from the proceeds portion of the diluted earnings per share calculations as they are no longer recorded in equity, which caused dilutive potential common shares outstanding to increase for all periods in fiscal 2016. 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. Marketable Securities Marketable securities consist of marketable equity securities and are classified as available-for-sale and stated at fair value. The cost basis of the marketable securities is based on the specific identification method. Unrealized gains or losses relating to available-for-sale securities are recorded in accumulated other comprehensive income, net of income taxes. Reclassification adjustments out of accumulated other comprehensive income resulting from realized gains or losses from the sale of available-for-sale securities are included in other income. During the year ended July 31, 2016 the Company sold all of its marketable securities. The cost basis of the marketable securities was $21.1 million and proceeds from the sale of the marketable securities was $21.5 million resulting in a realized gain of $0.4 million recorded in other income. 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, 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 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 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 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. No single customer accounted for more than 10 % of total revenues for the years ended July 31, 2016 , 2015 and 2014 . As of July 31, 2016 and 2015 , one customer accounted for more than 10 % of the Company’s accounts receivable. 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 seven 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 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 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, 2016 , 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 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, 2016 and 2015 was $49.4 million and $65.1 million , respectively. Accumulated amortization expense related to software as of July 31, 2016 and 2015 totaled $20.9 million and $42.6 million , respectively. During the year ended July 31, 2016 , the Company retired fully amortized capitalized software of $29.8 million , which were no longer being utilized. 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. For the year ended July 31, 2014, the Company recognized a charge of $29.1 million resulting primarily from the impairment of costs previously capitalized in connection with the development of the software. 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, 2016 2015 2014 Expected life (in years) 5.3 – 7.2 5.3 – 7.2 5.1 – 7.1 Risk-free interest rate 1.16 – 2.06 1.58 – 2.26 1.55 – 2.3 Estimated volatility 21 – 26 22 – 28 20 – 25 Expected dividends — % — % — % Weighted average fair value at measurement date $ 10.07 $ 10.18 $ 11.10 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. During the year ended July 31, 2016 , the Company early adopted ASU No. 2016-09, Improvements to Employee Share-Based Payment Accounting , which impacts the accounting for share-based payments, including income tax consequences, classification of awards and the classification on the consolidated statements of cash flows. As a result of the adoption, the Company recognized excess tax benefits of $14.7 million as a reduction to tax expense in the consolidated statements of income, as though ASU 2016-09 had been in effect since the beginning of fiscal 2016, instead of reflected in stockholders' equity. Net cash proceeds from the exercise of stock options were $13.2 million , $3.6 million and $10.4 million for the years ended July 31, 2016 , 2015 and 2014 , respectively. The Company realized an income tax benefit of $3.0 million and $2.3 million from stock option exercises during the years ended July 31, 2015 and 2014 , 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. 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 $500,000 stop loss per person. Our liability represents an estimate of the ultimate cost of claims incurred as of the balance sheet date, including an estimate for reported and unreported claims. 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. As of July 31, 2016 and 2015 , the total amount reserved for related self-insured claims is $5.3 million and $5.8 million , respectively. Comprehensive Income Comprehensive income includes all changes in stockholders’ equity during a period from non-stockholder sources. For the years ended July 31, 2016 , 2015 and 2014 , 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. 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 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, operating income and income before income taxes. The segments continue to share similar business models, services and economic characteristics although recent changes in management structure and continued growth in the Company's International region have resulted in the change in the reportable segments. Prior period reportable segment information has been adjusted to reflect the change in reportable segments. Recently Issued Accounting Pronouncements Adopted In March 2016, the FASB issued ASU No. 2016-09, Improvements to Employee Share-Based Payment Accounting , which simplifies several aspects of the accounting for share-based payments, including income tax consequences and classification on the statement of cash flows. Under the new standard, all excess tax benefits and tax deficiencies will be recognized as income tax expense or benefit in the income statement as discrete items in the reporting period in which they occur. Additionally, excess tax benefits will be classified as an operating activity on the consolidated statements of cash flows. In regards to forfeitures, the entity can make an accounting policy election to either recognize forfeitures as they occur or estimate the number of awards expected to be forfeited. This ASU is effective for annual periods beginning after December 15, 2016, including interim periods within those annual periods, with early adoption permitted. The Company early adopted ASU 2016-09 during the fourth quarter of fiscal 2016 on a modified retrospective basis. As a result of the adoption, the Company recognized excess tax benefits of $14.7 million as a reduction to tax expense in the consolidated statements of income, as though ASU 2016-09 had been in effect since the beginning of fiscal 2016, instead of reflected in stockholders' equity. The benefit was previously recorded within additional paid-in capital, representing the cumulative windfall tax benefit related to exercises of stock options. With respect to forfeitures, the Company will continue to estimate the number of awards expected to be forfeited in accordance with our existing accounting policy. In April 2015, the FASB issued ASU 2015-03, Interest - Imputation of Interest (Subtopic 835-30), which required 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 Company early adopted this guidance as of July 31, 2016. In connection with the Company's adoption of ASU 2015-03, prior year debt balances have been retrospectively adjusted to include a direct deduction of unamortized debt iss

Acquisitions	2 — Acquisitions Fiscal 2016 and Fiscal 2015 Transactions The Company made no acquisitions during the years ended July 31, 2016 and 2015. Fiscal 2014 Transactions During the year ended July 31, 2014, the Company acquired one facility in Montreal, Canada; a salvage vehicle auction business in Brazil, which did not include any facilities; as well as the assets of an online marketing company, which included the rights to hundreds of web domains including www.CashForCars.com and www.cash4cars.com. The aggregate purchase price totaled $14.5 million . During the year ended July 31, 2015, the purchase price allocations for the assets of the online marketing company and the salvage vehicle auction businesses in Montreal, Canada and Brazil were finalized. As a result, from the preliminary purchase price allocation as of July 31, 2014, goodwill decreased $0.8 million , primarily related to a $0.9 million increase in intangible assets, and changes to deferred taxes on acquired intangible assets. In accordance with ASC 805, any adjustments to the fair value of acquired assets and liabilities that occur subsequent to the measurement period will be reflected in the Company’s results of operations. The following table summarizes the purchase price allocation based on the estimated fair values of the assets acquired and liabilities assumed for these acquisitions (in thousands): Allocation of the acquisition: Accounts receivable and prepaid expenses $ 734 Property and equipment 71 Inventory 81 Intangible assets 6,071 Goodwill 7,682 Liabilities assumed (171 ) Fair value of net assets and liabilities acquired $ 14,468 These acquisitions were undertaken because of their strategic fit and have been accounted for using the purchase method in accordance with ASC 805, Business Combinations , which resulted in the recognition of goodwill in the Company’s consolidated financial statements. Goodwill arose because the purchase price of each acquisition reflected a number of factors, including their future earnings and cash flow potential; the multiple to earnings, cash flow and other factors at which similar businesses have been purchased by other acquirers; the competitive nature of the process by which the Company acquired these businesses; and the complementary strategic fit and resulting synergies brought to existing operations. Goodwill that arose from these acquisitions was within Level III of the fair value hierarchy as it was valued using unobservable inputs. Unobservable inputs reflect the Company’s best estimate of what hypothetical market participants would use to determine the value of acquired assets at the reporting date based on the best information available in the circumstances. When a determination is made to classify items within Level III of the fair value hierarchy, the evaluation is based upon the significance of the unobservable inputs to the overall fair value measurement. Due to the limitation of goodwill asset market value or pricing information, the determination of fair value of the goodwill asset is inherently more difficult. Goodwill is not amortized for financial reporting purposes but could be amortizable for tax purposes. The intangible assets that arose from these acquisitions were also within Level III of the fair value hierarchy as it was valued using unobservable inputs, primarily from utilizing the Multi-Period Excess Earnings Method (MPEEM) model, which is an income-based approach that allocates to goodwill any acquisition costs not specifically assigned to intangibles, fixed assets or working capital. Intangible assets acquired include covenants not to compete, supply contracts, customer relationships, trade names, licenses and databases and software with a useful life ranging from three to eight years . These acquisitions did not result in a significant change in the Company’s consolidated results of operations individually or in the aggregate; therefore, pro forma financial information has not been presented. The operating results have been included in the Company’s consolidated results of operations and financial position since the acquisition dates. The acquisition-related expenses incurred during the year ended July 31, 2014, were not significant and were included in general and administrative expenses in the Company’s consolidated financial position and results of operations.

Debt Disclosure [Abstract]
Long-Term Debt	8 — Long-Term Debt Credit Facility On December 14, 2010, the Company entered into an Amended and Restated Credit Facility Agreement (Credit Facility), with Bank of America, N.A. The Credit Facility was an unsecured credit agreement providing for (i) a $100.0 million revolving credit facility, including a $100.0 million alternative currency borrowing sublimit and a $50.0 million letter of credit sublimit and (ii) a term loan facility of $400.0 million . On September, 29, 2011, the Company amended the Credit Facility increasing the amount of the term loan facility from $400.0 million to $500.0 million . Credit Agreement On December 3, 2014 , the Company entered into a Credit Agreement with Wells Fargo Bank, National Association, as administrative agent, and Bank of America, N.A., as syndication agent, which superseded the Credit Facility. The Credit Agreement provided for (a) a secured revolving loan facility in an aggregate principal amount of up to $300.0 million , none of which was outstanding at July 31, 2015 (Revolving Loan Facility), and (b) a secured term loan facility in an aggregate principal amount of $300.0 million (Term Loan), which was fully drawn at closing. The Term Loan amortized $18.8 million per quarter. Proceeds from the Credit Agreement were used to repay all outstanding amounts under the Credit Facility totaling $275.0 million at December 3, 2014 . On March 15, 2016 , the Company entered into a First Amendment to Credit Agreement (the “Amendment to Credit Agreement”) with Wells Fargo Bank, National Association, as administrative agent and Bank of America, N.A. The Amendment to Credit Agreement amends certain terms of the Credit Agreement, dated as of December 3, 2014 . The Amendment to Credit Agreement provides for (a) an increase in the secured revolving credit commitments by $50.0 million , bringing the aggregate principal amount of the revolving credit commitments under the Credit Agreement to $350.0 million , (b) a new secured term loan (Incremental Term Loan) in the aggregate principal amount of $93.8 million having a maturity date of March 15, 2021 , and (c) an extension of the termination date of the Revolving Loan Facility and the maturity date of the Term Loan from December 3, 2019 to March 15, 2021 . The Amendment to Credit Agreement extended the amortization period for the Term Loan, and decreased the quarterly amortization payments for that loan to $7.5 million per quarter. The Amendment to Credit Agreement additionally reduced the pricing levels under the Credit Agreement to a range of 0.15% to 0.30% in the case of the commitment fee, 1.125% to 2.0% in the case of the applicable margin for LIBOR loans, and 0.125% to 1.0% in the case of the applicable margin for base rate loans, based on the Company’s consolidated total net leverage ratio during the preceding fiscal quarter. The Company borrowed the entire $93.8 million principal amount of the Incremental Term Loan concurrent with the closing of the Amendment to Credit Agreement. On July 21, 2016 , the Company entered into a Second Amendment to Credit Agreement (the “Second Amendment to Credit Agreement”) with Wells Fargo Bank, National Association, SunTrust Bank, and Bank of America, N.A., as administrative agent (as successor in interest to Wells Fargo Bank). The Second Amendment to Credit Agreement amends certain terms of the Credit Agreement, dated as of December 3, 2014 . The Second Amendment to Credit Agreement provides for, among other things, (a) an increase in the secured revolving credit commitments by $500.0 million , bringing the aggregate principal amount of the revolving credit commitments under the Credit Agreement to $850.0 million , (b) the repayment of existing term loans outstanding under the Credit Agreement, (c) an extension of the termination date of the revolving credit facility under the Credit Agreement from March 15, 2021 to July 21, 2021 and (d) increased covenant flexibility. Concurrent with the closing of the Second Amendment to Credit Agreement, the Company prepaid in full the outstanding $242.5 million principal amount of the Term Loan and Incremental Term Loan under the Credit Agreement without premium or penalty. The Second Amendment to Credit Agreement reduced the pricing levels under the Credit Agreement to a range of 0.125% to 0.20% in the case of the commitment fee, 1.00% to 1.75% in the case of the applicable margin for LIBOR loans, and 0.0% to 0.75% in the case of the applicable margin for base rate loans, in each case depending on the Company’s consolidated total net leverage ratio. The principal purposes of these financing transactions were to increase the size and availability under the Company's Revolving Loan Facility and to provide additional long-term financing. The proceeds are being used for general corporate purposes, including working capital and capital expenditures, potential share repurchases, acquisitions, or other investments relating to the Company’s expansion strategies in domestic and international markets. The Revolving Loan Facility under the Credit Agreement bears interest, at the election of the Company, at either (a) the Base Rate, which is defined as a fluctuating rate per annum equal to the greatest of (i) the Prime Rate in effect on such day; (ii) the Federal Funds Rate in effect on such date plus 0.50% ; or (iii) an adjusted LIBOR rate determined on the basis of a one-month interest period plus 1.0% , in each case plus an applicable margin ranging from 0.0% to 0.75% based on the Company's consolidated total net leverage ratio during the preceding fiscal quarter; or (b) an adjusted LIBOR rate plus an applicable margin ranging from 1.00% to 1.75% depending on the Company’s consolidated total net leverage ratio during the preceding fiscal quarter. Interest is due and payable quarterly, in arrears, for loans bearing interest at the Base Rate, and at the end of an interest period (or at each three month interval in the case of loans with interest periods greater than three months) in the case of loans bearing interest at the adjusted LIBOR rate. The interest rate as of July 31, 2016 on the Company's variable interest rate debt was the one month LIBOR rate of 0.49% plus an applicable margin of 1.25% . The carrying amount of the Credit Agreement is comprised of borrowings under which interest accrues under a fluctuating interest rate structure. Accordingly, the carrying value approximates fair value at July 31, 2016 , and was classified within Level II of the fair value hierarchy. Amounts borrowed under the Revolving Loan Facility may be repaid and reborrowed until the maturity date of July 21, 2021 . The Company is obligated to pay a commitment fee on the unused portion of the Revolving Loan Facility. The commitment fee rate ranges from 0.125% to 0.20% , depending on the Company’s consolidated total net leverage ratio during the preceding fiscal quarter, on the average daily unused portion of the revolving credit commitment under the Credit Agreement. The Company had $238.0 million of outstanding borrowings under the Revolving Loan Facility as of July 31, 2016 and no outstanding borrowings as of July 31, 2015 . The Company’s obligations under the Credit Agreement are guaranteed by certain of the Company’s domestic subsidiaries meeting materiality thresholds set forth in the Credit Agreement. Such obligations, including the guaranties, are secured by substantially all of the assets of the Company and the assets of the subsidiary guarantors pursuant to a Security Agreement, dated December 3, 2014 , among the Company, the subsidiary guarantors from time to time party thereto, and Wells Fargo Bank, National Association, as collateral agent. The Credit Agreement contains customary affirmative and negative covenants, including covenants that limit or restrict the Company and its subsidiaries’ ability to, among other things, incur indebtedness, grant liens, merge or consolidate, dispose of assets, make investments, make acquisitions, enter into transactions with affiliates, pay dividends, or make distributions on and repurchase stock, in each case subject to certain exceptions. The Company is also required to maintain compliance, measured at the end of each fiscal quarter, with a consolidated total net leverage ratio and a consolidated interest coverage ratio. The Company was in compliance with all covenants related to the Credit Agreement as of July 31, 2016 . Note Purchase Agreement On December 3, 2014 , the Company entered into a Note Purchase Agreement and sold to certain purchasers (collectively, the Purchasers) $400.0 million in aggregate principal amount of senior secured notes (Senior Notes) consisting of (i) $100.0 million aggregate principal amount of 4.07% Senior Notes, Series A, due December 3, 2024 ; (ii) $100.0 million aggregate principal amount of 4.19% Senior Notes, Series B, due December 3, 2026 ; (iii) $100.0 million aggregate principal amount of 4.25% Senior Notes, Series C, due December 3, 2027 ; and (iv) $100.0 million aggregate principal amount of 4.35% Senior Notes, Series D, due December 3, 2029 . Interest is due and payable quarterly, in arrears, on each of the Senior Notes. Proceeds from the Note Purchase Agreement are being used for general corporate purposes. On July 21, 2016 , the Company entered into Amendment No. 1 to Note Purchase Agreement (the First Amendment to Note Purchase Agreement) which amended certain terms of the Note Purchase Agreement, including providing for increased flexibility substantially consistent with the changes included in the Second Amendment to Credit Agreement, including among other things increased covenant flexibility. The Company may prepay the Senior Notes, in whole or in part, at any time, subject to certain conditions, including minimum amounts and payment of a make-whole amount equal to the discounted value of the remaining scheduled interest payments under the Senior Notes. The Company’s obligations under the Note Purchase Agreement are guaranteed by certain of the Company’s domestic subsidiaries meeting materiality thresholds set forth in the Note Purchase Agreement. Such obligations, including the guaranties, are secured by substantially all of the assets of the Company and the subsidiary guarantors. The obligations of the Company and its subsidiary guarantors under the Note Purchase Agreement will be treated on a pari passu basis with the obligations of those entities under the Credit Agreement as well as any additional debt the Company may obtain. The Note Purchase Agreement contains customary affirmative and negative covenants, including covenants that limit or restrict the Company and its subsidiaries’ ability to, among other things, incur indebtedness, grant liens, merge or consolidate, dispose of assets, make investments, make acquisitions, enter into transactions with affiliates, pay dividends, or make distributions and repurchase stock, in each case subject to certain exceptions.

Related to the execution of the Credit Agreement, First Amendment to Credit Agreement, Second Amendment to Credit Agreement, and the Note Purchase Agreement, the Company incurred $3.4 million in costs, of which $2.0 million was capitalized as debt issuance fees and $1.4 million was recorded as a reduction of the long-term debt proceeds as a debt discount. During the year ended July 31, 2016 , the Company recognized an expense of $0.6 million for prior capitalized costs into interest expense relating to the Second Amendment to Credit Agreement and payoff of the outstanding Term Loans. Both the debt issuance fees and debt discount are amortized to interest expense over the term of the respective debt instruments and are classified as reductions of the outstanding liability. As of July 31, 2016 , future payments on the Revolving Loan Facility and Note Purchase Agreement were as follows: (In thousands) July 31, (1) 2017 $ 75,000 2018 163,000 2019 — 2020 — 2021 — Thereafter 400,000 Total future payments $ 638,000 (1) Fiscal 2017 and 2018 payments assume payoff of the current portion of the Revolving Loan Facility in fiscal 2017 and the long-term portion of the Revolving Loan Facility in fiscal 2018 based on management's intent of the use of the Revolving Loan Facility, which may change on a quarter by quarter basis.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives and Hedging	9 — Derivatives and Hedging The Company had entered into two interest rate swaps to exchange its variable interest rate payments commitment for fixed interest rate payments through December 2015. The swaps were designated effective cash flow hedges under ASC 815, Derivatives and Hedging . Each quarter, the Company measured hedge effectiveness using the “ hypothetical derivative method ” and recorded in earnings any hedge ineffectiveness with the effective portion of the change in fair value recorded in other comprehensive income or loss. The interest rate swaps expired in December 2015. The Company reclassified $0.5 million , $1.7 million , and $2.2 million for the years ended July 31, 2016 , 2015 and 2014 respectively, out of other comprehensive income into interest expense. The interest rate swaps were classified within Level II of the fair value hierarchy as the derivatives were valued using observable inputs. The Company determined fair value of the derivative utilizing observable market data of swap rates and basis rates. These inputs were placed into a pricing model using a discounted cash flow methodology in order to calculate the mark-to-market value of the interest rate swaps. As of July 31, 2015 , the Company’s fair value of the interest rate swaps was $0.4 million and was classified as other liabilities in the consolidated balance sheets.

Equity [Abstract]
Shareholders' Equity	11 — Stockholders’ Equity General The Company has authorized the issuance of 180 million shares of common stock, with a par value of $0.0001 , of which 110,122,060 shares were issued and outstanding at July 31, 2016 . As of July 31, 2016 and 2015 , the Company had reserved 20,812,967 and 22,682,820 shares of common stock, respectively, for the issuance of options granted under the Company’s stock option plans and 989,811 and 1,097,943 shares of common stock, respectively, for the issuance of shares under the Copart, Inc. Employee Stock Purchase Plan (ESPP). The Company has authorized the issuance of five million shares of preferred stock, with a par value of $0.0001 , none of which were issued or outstanding at July 31, 2016 or 2015 , which have the rights and preferences as the Company’s Board of Directors shall determine, from time to time. Stock Repurchases On September 22, 2011, our Board of Directors approved a 40 million share increase in the stock repurchase program, bringing the total current authorization to 98 million shares. The repurchases may be effected through solicited or unsolicited transactions in the open market or in privately negotiated transactions. No time limit has been placed on the duration of the stock repurchase program. Subject to applicable securities laws, such repurchases will be made at such times and in such amounts as the we deem appropriate and may be discontinued at any time. For fiscal 2016 we repurchased 2,938,519 shares of our common stock at a weighted average price of $40.13 per share totaling $117.9 million . For fiscal 2015, we repurchased 231,500 shares of our common stock at a weighted average price of $36.02 per share totaling $8.3 million . For fiscal 2014, we did not repurchase any common stock. As of July 31, 2016 , the total number of shares repurchased under the program was 53,456,801 and 44,543,199 shares were available for repurchase under the program. On July 9, 2015 , the Company completed a modified "Dutch Auction" tender offer, or tender offer, to purchase up to 13,888,888 shares of our common stock at a price not greater than $36.00 nor less than $34.75 per share. In connection with the tender offer, we accepted for payment an aggregate of 6,254,061 shares of our common stock at a purchase price of $36.00 per share for a total value of $225.1 million . Additionally, on December 30, 2015 , the Company completed a modified "Dutch Auction" tender offer, or tender offer, to purchase up to 7,317,073 shares of our common stock at a price not greater than $41.00 nor less than $38.00 per share. In connection with the tender offer, the Company accepted for payment an aggregate of 8,333,333 shares of its common stock at a purchase price of $39.00 per share for a total value of $325.0 million . The Company's directors and executive officers did not participate in the tender offers. The shares purchased as a result of the tender offers were not part of the Company's stock repurchase program. During fiscal 2016 , 2015 and 2014 , certain executive officers and employees exercised stock options through cashless exercises. A portion of the options exercised were net settled in satisfaction of the exercise price and federal and state minimum statutory tax withholding requirements. The Company remitted $15.0 million , $3.8 million and $0.1 million for the years ended July 31, 2016 , 2015 and 2014 , respectively, to the proper taxing authorities in satisfaction of the employees’ minimum statutory withholding requirements. The exercised stock options, utilizing a cashless exercise, are summarized in the following table: Period Options Exercised Exercise Price Shares Net Settled for Exercise Shares Withheld for Taxes(1) Net Shares to Employee Share Price for Withholding Tax Withholding (in 000s) FY 2014—Q1 14,000 $ 16.43 7,241 2,519 4,240 $ 31.77 $ 80 FY 2015—Q1 201,333 19.59 124,621 35,416 41,296 31.65 1,121 FY 2015—Q3 139,690 20.27 76,021 20,656 43,013 37.27 770 FY 2015—Q4 200,000 12.02 66,602 52,158 81,240 36.08 1,882 FY 2016—Q4 1,130,000 18.64 410,648 293,152 426,200 51.30 15,039 (1) Shares withheld for taxes are treated as a repurchase of shares for accounting purposes but do not count against the Company’s stock repurchase program. Employee Stock Purchase Plan The ESPP provides for the purchase of up to an aggregate of 5 million shares of common stock of the Company by employees pursuant to the terms of the ESPP. The Company’s ESPP was adopted by the Board of Directors and approved by the stockholders in 1994. The ESPP was amended and restated in 2003 and again approved by the stockholders. In 2014, a new ESPP was approved by the Board of Directors and approved by the stockholders. Under the ESPP, employees of the Company who elect to participate have the right to purchase common stock at a 15% discount from the lower of the market value of the common stock at the beginning or the end of each six month offering period. The ESPP permits an enrolled employee to make contributions to purchase shares of common stock by having withheld from their salary an amount up to 10% of their compensation (which amount may be increased from time to time by the Company but may not exceed 15 % of compensation). No employee may purchase more than $25,000 worth of common stock (calculated at the time the purchase right is granted) in any calendar year. The Compensation Committee of the Board of Directors administers the ESPP. The number of shares of common stock issued pursuant to the ESPP during the years ended July 31, 2016 , 2015 and 2014 was 108,132 ; 101,015 ; and 81,967 , respectively. As of July 31, 2016 , there were 4,050,226 shares of common stock issued pursuant to the ESPP and 989,811 shares remain available for purchase under the ESPP. Stock Options In December 2007, the Company adopted the Copart, Inc. 2007 Equity Incentive Plan (Plan), presently covering an aggregate of 8.0 million shares of the Company’s common stock. The Plan provides for the grant of incentive stock options, restricted stock, restricted stock units and other equity-based awards to employees and non-qualified stock options, restricted stock, restricted stock units and other equity-based awards to employees, officers, directors and consultants at prices not less than 100% of the fair market value for incentive and non-qualified stock options, as determined by the Board of Directors at the grant date. Incentive and non-qualified stock options may have terms of up to ten years and vest over periods determined by the Board of Directors. Options generally vest ratably over a five -year period. The Plan replaced the Company’s 2001 Stock Option Plan. As of July 31, 2016 , 1,360,067 shares were available for grant under the Plan. In April 2009, the Compensation Committee of the Company’s Board of Directors, subject to stockholder approval (which was subsequently obtained at the April 14, 2009 special meeting of stockholders), approved the grant to each of Willis J. Johnson, the Company’s Chairman (and then Chief Executive Officer), and A. Jayson Adair, the Company’s Chief Executive Officer (and then President), of nonqualified stock options to purchase 4,000,000 shares of the Company’s common stock at an exercise price of $15.11 per share, which equaled the closing price of the Company’s common stock on April 14, 2009, the effective date of grant. Such grants were made in lieu of any cash salary or bonus compensation in excess of $1.00 per year or the grant of any additional equity incentives for a five -year period. Each option became exercisable over five years , due to continued service by the executive, with 20% vesting on April 14, 2010, and the balance vesting ratably over the subsequent four years. Each option became fully vested due to continued service on April 14, 2014, the fifth anniversary of the date of grant. The total compensation expense recognized by the Company over the five year service period was $26.1 million per grant. The Company recognized no compensation expense in the years ended July 31, 2016 and 2015 and $7.2 million for the year ended July 31, 2014 , relating to these grants. In October 2013, the Compensation Committee of the Company’s Board of Directors, subject to stockholder approval (which was subsequently obtained at the December 16, 2013 annual meeting of stockholders), approved the grant to each of A. Jayson Adair, the Company’s Chief Executive Officer, and Vincent W. Mitz, the Company’s President, of nonqualified stock options to purchase 2,000,000 and 1,500,000 shares of the Company’s common stock, respectively, at an exercise price of $35.62 per share, which equaled the closing price of the Company’s common stock on December 16, 2013, the effective date of grant. Such grants were made in lieu of any cash salary or bonus compensation in excess of $1.00 per year or the grant of any additional equity incentives for a five -year period. Each option will become exercisable over five years , subject to continued service by Mr. Adair and Mr. Mitz, with 20% vesting on April 15, 2015 and December 16, 2014, respectively, and the balance vesting monthly over the subsequent four years. Each option will become fully vested, assuming continued service, on April 15, 2019 and December 16, 2018, respectively. If, prior to a change in control, either executive’s employment is terminated without cause, then 100% of the shares subject to that executive’s stock option will immediately vest. If, upon or following a change in control, either the Company or a successor entity terminates the executive’s service without cause, or the executive resigns for good reason (as defined in the option agreement), then 100% of the shares subject to his stock option will immediately vest. On June 2, 2015, the Compensation Committee of the Company’s Board of Directors approved the amendment of each of the stand-alone stock option agreements, by and between the Company and A. Jayson Adair and Vincent W. Mitz, respectively, to remove the provision providing at times prior to a “change in control” for the immediate vesting in full of the underlying option upon an involuntary termination of Mr. Adair or Mr. Mitz, as applicable, without “cause.” The fair value of each option at the date of grant was $11.43 . The total estimated compensation expense to be recognized by the Company over the five year estimated service period for these options is $40.0 million . The Company recognized $7.5 million in compensation expenses for these grants in the years ended July 31, 2016 and 2015 , respectively and $4.7 million in 2014. The following table details stock-based payment compensation expense included in the company’s consolidated statements of income: Year Ended July 31, (In thousands) 2016 2015 2014 General and administrative $ 18,194 $ 15,938 $ 19,489 Yard operations 2,670 2,216 2,610 Total stock-based payment compensation $ 20,864 $ 18,154 $ 22,099 There were no material compensation costs capitalized as part of the cost of an asset as of July 31, 2016 and 2015 . A summary of the status of the Company’s non-vested shares and its activity during the year ended July 31, 2016 was as follows: (In thousands, except per share amounts) Number of Shares Weighted Average Grant- date Fair Value Non-vested shares at July 31, 2015 6,615 $ 10.48 Grants of non-vested shares 432 10.07 Vested (2,074 ) 10.12 Forfeitures or expirations (162 ) 8.63 Non-vested shares at July 31, 2016 4,811 $ 10.66 Stock option activity for the year ended July 31, 2016 was as follows: (In thousands, except per share and term data) Shares Weighted Average Exercise Price Weighted Average Remaining Contractual Term (In years) Aggregate Intrinsic Value Outstanding as of July 31, 2015 21,011 $ 23.65 5.78 $ 261,339 Grants of options 432 38.71 Exercises (1,830 ) 19.19 Forfeitures or expirations (162 ) 35.87 Outstanding as of July 31, 2016 19,451 $ 24.30 4.96 $ 508,401 Exercisable as of July 31, 2016 14,640 $ 20.47 3.91 $ 438,774 Vested and expected to vest as of July 31, 2016 19,121 $ 24.10 4.90 $ 503,601 As required by ASC 718 , Compensation — Stock Compensation , the Company made an estimate of expected forfeitures and recognized compensation cost only for those equity awards expected to vest. The aggregate intrinsic value in the table above represents the total pretax intrinsic value (i.e., the difference between the Company’s closing stock price on the last trading day of the year ended July 31, 2016 and the exercise price, times the number of shares) that would have been received by the option holders had all option holders exercised their options on July 31, 2016 . The aggregate intrinsic value of options exercised was $53.6 million , $13.4 million and $10.5 million in the years ended July 31, 2016 , 2015 and 2014 , respectively, and represents the difference between the exercise price of the option and the estimated fair value of the Company’s common stock on the dates exercised. As of July 31, 2016 , the total compensation cost related to non-vested stock-based payment awards granted to employees under the Company’s stock option plans but not yet recognized was $45.5 million , net of estimated forfeitures. This cost will be amortized on a straight-line basis over a weighted average remaining term of 2.99 years and will be adjusted for subsequent changes in estimated forfeitures. The fair value of options vested for the years ended July 31, 2016 , 2015 and 2014 was $21.0 million , $19.5 million and $15.0 million , respectively. The following table summarizes stock options outstanding and exercisable as of July 31, 2016 : (In thousands, except per share amount) Options Outstanding Options Exercisable Range of Exercise Prices Number Weighted Average Remaining Contractual Life Weighted Average Exercise Price Number Weighted Average Exercise Price $13.08–$15.11 8,056 2.70 $ 15.09 8,056 $ 15.09 $16.38–$19.78 2,119 2.27 17.29 2,119 17.29 $20.56–$35.62 6,851 7.27 32.81 3,617 30.56 $35.72–$49.51 2,425 8.27 37.00 848 36.48 19,451 4.96 24.30 14,640 20.47

Under this standard, all excess tax benefits and tax deficiencies related to exercises of stock options are recognized as income tax expense or benefit in the income statement as discrete items in the reporting period in which they occur. The tax effects of temporary differences that give rise to significant portions of the deferred tax assets (liabilities) are presented below: July 31, (In thousands) 2016 2015 Deferred tax assets: Allowance for doubtful accounts $ 1,396 $ 992 Accrued compensation and benefits 43,594 40,391 State taxes 638 577 Accrued other 3,018 3,967 Deferred revenue (545 ) 798 Property and equipment 14,170 16,957 Losses carried forward 3,312 4,362 Federal tax benefit 10,757 7,832 Total gross deferred tax assets 76,340 75,876 Less valuation allowance (5,420 ) (2,650 ) Net deferred tax assets 70,920 73,226 Deferred tax liabilities: Vehicle pooling costs (8,871 ) (7,749 ) Prepaid insurance (1,142 ) (890 ) Intangibles and goodwill (39,773 ) (37,673 ) Total gross deferred tax liabilities (49,786 ) (46,312 ) Net deferred tax assets $ 21,134 $ 26,914 The above net deferred tax assets and liabilities have been reflected in the accompanying consolidated balance sheets as follows: July 31, (In thousands) 2016 2015 U.S. current assets $ 1,444 $ 3,396 U.S. non-current assets 23,506 28,856 International non-current liabilities (3,816 ) (5,338 ) Net deferred tax assets $ 21,134 $ 26,914 The Company’s ability to realize deferred tax assets is dependent on its ability to generate future taxable income. Accordingly, the Company has established a valuation allowance in taxable jurisdictions where the utilization of the tax assets is uncertain. Additional timing differences or future tax losses may occur which could warrant a need for establishing additional valuation allowances against certain deferred tax assets. The valuation allowance for the years ended July 31, 2016 and 2015 was $5.4 million and $2.7 million , respectively. As of July 31, 2016 and 2015 , if recognized, the portion of liabilities for unrecognized tax benefits that would favorably affect the Company’s effective tax rate w as $20.7 million and $17.4 million , respectively. It is possible that the amount of unrecognized tax benefits will change in the next twelve months, due to tax legislation updates or future audit outcomes; however an estimate of the range of the possible change cannot be made at this time. The following table summarizes the activities related to the Company’s unrecognized tax benefits: July 31, (In thousands) 2016 2015 2014 Beginning balance $ 17,428 $ 18,419 $ 17,178 Increases related to current year tax position 4,311 3,441 1,805 Prior year tax positions: Prior year increase 1,120 599 2,997 Prior year decrease — — (523 ) Cash settlement (412 ) (225 ) — Lapse of statute of limitations (1,732 ) (4,806 ) (3,038 ) Ending balance $ 20,715 $ 17,428 $ 18,419 It is the Company’s continuing practice to recognize interest and penalties related to income tax matters in income tax expense. As of July 31, 2016 , 2015 and 2014 , the Company had accrued interest and penalties related to unrecognized tax benefits of $4.9 million , $3.8 million and $5.4 million , respectively. The Company is currently under examination by certain taxing authorities in the U.S. for fiscal years 2011 to 2014. At this time, the Company does not believe that the outcome of any examination will have a material impact on the Company’s consolidated results of operations and financial position. During the year ended July 31, 2016 , the Company early adopted ASU No. 2016-09, Improvements to Employee Share-Based Payment Accounting , which impacts the accounting for share-based payments, including income tax consequences, classification of awards and the classification on the consolidated statements of cash flows. As a result of the adoption, the Company recognized excess tax benefits of $14.7 million as a reduction to tax expense in the consolidated statements of income, as though ASU 2016-09 had been in effect since the beginning of fiscal 2016, instead of reflected in stockholders' equity. In the years ended July 31, 2015 and 2014 , the Company recognized a tax benefit of $3.0 million and $2.3 million , respectively, upon the exercise of certain stock options, which was reflected in stockholders’ equity. The Company has not provided for U.S. federal income and foreign withholding taxes on i ts $146.0 million in ternational subsidiaries’ undistributed earnings as of July 31, 2016 , because the Company intends to reinvest such earnings indefinitely in its international operations. Specifically, the earnings will be dedicated to the following areas outside the U.S. (i) funding operating and capital spending needs in existing foreign markets; (ii) funding merger and acquisition deals both in existing and new international markets; and (iii) other investments to help expand the Company's footprint in international emerging markets. The Company does not anticipate the need for any international cash in the U.S. operations. It is not practical to determine the income tax liability that might be incurred if these earnings were to be distributed in the form of dividends or otherwise. If distributed, however, foreign tax credits may become available under current law to reduce or eliminate the resultant U.S. income tax liability.

During the year ended July 31, 2016 , the Company early adopted ASU No. 2016-09, Improvements to Employee Share-Based Payment Accounting , which caused an impact on dilutive potential common shares outstanding, as the Company excluded the excess tax benefits and deficiencies from the proceeds portion of the diluted earnings per share calculations as they are no longer recorded in equity, which caused dilutive potential common shares outstanding to increase for all periods in fiscal 2016.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	15 — Commitments and Contingencies Leases The Company leases certain facilities and certain equipment under non-cancelable capital and operating leases. In addition to the minimum future lease commitments presented below, the leases generally require the Company to pay property taxes, insurance, maintenance and repair cost which are not included in the table because the Company has determined these items are not material. Certain leases provide the Company with either a right of first refusal to acquire or an option to purchase a facility at fair value. Certain leases also contain escalation clauses and renewal option clauses calling for increased rents. Where a lease contains an escalation clause or a concession, such as a rent holiday or tenant improvement allowance, rent expense is recognized on a straight-line basis over the lease term in accordance with ASC 840, Operating Leases. The future minimum lease commitments for the next five fiscal years, under non-cancelable capital and operating leases with initial or remaining lease terms in excess of one year were as follows: Year Ended July 31, (In thousands) 2017 2018 2019 2020 2021 Thereafter Subtotal Less Amount Representing Interest Total Operating leases $ 23,217 $ 20,154 $ 16,179 $ 12,777 $ 9,847 $ 61,904 $ 144,078 $ — $ 144,078 Capital leases 1,124 1,093 909 — — — 3,126 (194 ) 2,932 Facilities rental expense for the years ended July 31, 2016 , 2015 and 2014 was $21.6 million , $21.7 million and $26.4 million , respectively. Yard operations equipment rental expense for the years ended July 31, 2016 , 2015 and 2014 was $3.1 million , $3.6 million and $3.0 million , respectively. Commitments Letters of Credit Under a letter of credit facility separate from our Revolving Loan Facility, the Company had outstanding letters of credit of $15.3 million at July 31, 2016 , which are primarily used to secure certain insurance obligations. Contingencies Legal Proceedings The Company is subject to threats of litigation and is involved in actual litigation and damage claims arising in the ordinary course of business, such as actions related to injuries, property damage, contract disputes, and handling or disposal of vehicles. The material pending legal proceedings to which the Company is a party, or of which any of the Company’s property is subject, include the following matters. On November 1, 2013, the Company filed suit against Sparta Consulting, Inc. (now known as KPIT) in the 44th Judicial District Court of Dallas County, Texas, alleging fraud, fraudulent inducement, and/or promissory fraud, negligent misrepresentation, unfair business practices pursuant to California Business and Professions Code § 17200, breach of contract, declaratory judgment, and attorney’s fees. The Company seeks compensatory and exemplary damages, disgorgement of amounts paid, attorney’s fees, pre- and post-judgment interest, costs of suit, and a judicial declaration of the parties’ rights, duties, and obligations under the Implementation Services Agreement dated October 6, 2011. The suit arises out of the Company’s September 17, 2013 decision to terminate the Implementation Services Agreement, under which KPIT was to design, implement, and deliver a customized replacement enterprise resource planning system for the Company. On January 2, 2014, KPIT removed this suit to the United States District Court for the Northern District of Texas. On August 11, 2014, the Northern District of Texas transferred the suit to the United States District Court for the Eastern District of California for convenience. On January 8, 2014, KPIT filed suit against the Company in the United States District Court for the Eastern District of California, alleging breach of contract, promissory estoppel, breach of the implied covenant of good faith and fair dealing, account stated, quantum meruit, unjust enrichment, and declaratory relief. KPIT seeks compensatory and exemplary damages, prejudgment interest, costs of suit, and a judicial declaration of the parties’ rights, duties, and obligations under the Implementation Services Agreement. On June 8, 2016, the Company amended its complaint to include claims that KPIT stole certain intellectual property owned by the Company and acted negligently in its provision of services. The Company is pursuing its claim for damages, and defending against KPIT’s claim for damages. The Company provides for costs relating to these matters when a loss is probable and the amount can be reasonably estimated. The effect of the outcome of these matters on the Company’s future consolidated results of operations and cash flows cannot be predicted because any such effect depends on future results of operations and the amount and timing of the resolution of such matters. The Company believes that any ultimate liability will not have a material effect on its consolidated results of operations, financial position or cash flows. However, the amount of the liabilities associated with these claims, if any, cannot be determined with certainty. The Company maintains insurance which may or may not provide coverage for claims made against the Company. There is no assurance that there will be insurance coverage available when and if needed. Additionally, the insurance that the Company carries requires that the Company pay for costs and/or claims exposure up to the amount of the insurance deductibles negotiated when the insurance is purchased. Governmental Proceedings The Georgia Department of Revenue, or DOR, has conducted a sales and use tax audit of the Company’s operations in Georgia for the period from January 1, 2007 through June 30, 2011. As a result of their initial audit, the DOR issued a notice of proposed assessment for uncollected sales taxes in which it asserted that the Company failed to collect and remit sales taxes totaling $73.8 million , including penalties and interest. According to the DOR, the proposed assessment was based on its initial determination that the Company's sales did not constitute nontaxable sales for resale. The Company subsequently engaged a Georgia law firm and outside tax advisors to review the conduct of its business operations in Georgia, the notice of proposed assessment, and the DOR’s policy position. In particular, the Company’s outside legal counsel provided the Company an opinion that the sales for resale to non-U.S. registered resellers should not be subject to Georgia sales and use tax. In rendering its opinion, the Company’s counsel noted that non-U.S. registered resellers are unable to comply strictly with technical requirements for a Georgia certificate of exemption but concluded that its sales for resale to non-U.S. registered resellers should not be subject to Georgia sales and use tax notwithstanding this technical inability to comply. Since the Company's receipt of the notice of proposed assessment, the Company and its counsel have engaged in active discussions with the DOR to resolve the matter. On June 5, 2015 , following the Company's discussions and after additional review of documentation, the DOR provided the Company with revised audit work papers computing a sales tax liability of $2.7 million before interest and any penalties. On June 22, 2015 , representatives of the DOR and the Office of the Attorney General for the State of Georgia informed the Company's counsel that the DOR intended to issue a formal notice of assessment for an estimated $100.0 million , based on the DOR’s original proposed assessment of $73.8 million plus additional accumulated interest and penalties. On August 4, 2015 , the DOR issued an official Assessment and Demand for Payment for $96.1 million for sales taxes, penalties, and interest that the DOR alleges the Company owes the State of Georgia. The Company filed an appeal of this notice of assessment from the DOR with the Georgia Tax Tribunal on September 3, 2015. On August 5, 2016, the DOR filed a response in which it denied all allegations noted in the Company's appeal of the notice of assessment. The Company continues to substantiate its position that these transactions are nontaxable sales for resale by providing the DOR with documentation supporting the exempt nature of these sales. Based on the opinion from the Company’s outside law firm, advice from its outside tax advisors, and the Company's best estimate of a probable outcome, the Company has adequately provided for the payment of any assessment in its consolidated financial statements. The Company believes it has strong defenses to the DOR’s notice of assessment and intends to defend this matter. There can be no assurance that this matter will be resolved in the Company’s favor or that the Company will not ultimately be required to make a substantial payment to the Georgia DOR. The Company understands that litigating and defending the matter in Georgia could be expensive and time-consuming and result in substantial management distraction. If the matter were to be resolved in a manner adverse to the Company, it could have a material adverse effect on the Company’s consolidated results of operations and financial position.

Summary of Significant Accoun27

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Jul. 31, 2016
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 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 the 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 its 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.
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, Indian rupee, 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, accrued liabilities and Revolving Loan Facility approximated their fair values as of July 31, 2016 and 2015 , 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 , Note 10 – Fair Value Measures , and Note 10 – Fair Value Measures .
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, earnings from unconsolidated affiliates, and currency related gains and losses.
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.
Marketable Securities, Policy [Policy Text Block]	Marketable Securities Marketable securities consist of marketable equity securities and are classified as available-for-sale and stated at fair value. The cost basis of the marketable securities is based on the specific identification method. Unrealized gains or losses relating to available-for-sale securities are recorded in accumulated other comprehensive income, net of income taxes. Reclassification adjustments out of accumulated other comprehensive income resulting from realized gains or losses from the sale of available-for-sale securities are included in other income.
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 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 seven 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, 2016 , 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, 2016 and 2015 was $49.4 million and $65.1 million , respectively. Accumulated amortization expense related to software as of July 31, 2016 and 2015 totaled $20.9 million and $42.6 million , respectively. During the year ended July 31, 2016 , the Company retired fully amortized capitalized software of $29.8 million , which were no longer being utilized. 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.
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, 2016 2015 2014 Expected life (in years) 5.3 – 7.2 5.3 – 7.2 5.1 – 7.1 Risk-free interest rate 1.16 – 2.06 1.58 – 2.26 1.55 – 2.3 Estimated volatility 21 – 26 22 – 28 20 – 25 Expected dividends — % — % — % Weighted average fair value at measurement date $ 10.07 $ 10.18 $ 11.10 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. During the year ended July 31, 2016 , the Company early adopted ASU No. 2016-09, Improvements to Employee Share-Based Payment Accounting , which impacts the accounting for share-based payments, including income tax consequences, classification of awards and the classification on the consolidated statements of cash flows. As a result of the adoption, the Company recognized excess tax benefits of $14.7 million as a reduction to tax expense in the consolidated statements of income, as though ASU 2016-09 had been in effect since the beginning of fiscal 2016, instead of reflected in stockholders' equity. Net cash proceeds from the exercise of stock options were $13.2 million , $3.6 million and $10.4 million for the years ended July 31, 2016 , 2015 and 2014 , respectively. The Company realized an income tax benefit of $3.0 million and $2.3 million from stock option exercises during the years ended July 31, 2015 and 2014 , 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.
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 $500,000 stop loss per person. Our liability represents an estimate of the ultimate cost of claims incurred as of the balance sheet date, including an estimate for reported and unreported claims. 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.
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, 2016 , 2015 and 2014 , 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.
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 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, operating income and income before income taxes. The segments continue to share similar business models, services and economic characteristics although recent changes in management structure and continued growth in the Company's International region have resulted in the change in the reportable segments.
Recently Issued Accounting Standards	Recently Issued Accounting Pronouncements Adopted In March 2016, the FASB issued ASU No. 2016-09, Improvements to Employee Share-Based Payment Accounting , which simplifies several aspects of the accounting for share-based payments, including income tax consequences and classification on the statement of cash flows. Under the new standard, all excess tax benefits and tax deficiencies will be recognized as income tax expense or benefit in the income statement as discrete items in the reporting period in which they occur. Additionally, excess tax benefits will be classified as an operating activity on the consolidated statements of cash flows. In regards to forfeitures, the entity can make an accounting policy election to either recognize forfeitures as they occur or estimate the number of awards expected to be forfeited. This ASU is effective for annual periods beginning after December 15, 2016, including interim periods within those annual periods, with early adoption permitted. The Company early adopted ASU 2016-09 during the fourth quarter of fiscal 2016 on a modified retrospective basis. As a result of the adoption, the Company recognized excess tax benefits of $14.7 million as a reduction to tax expense in the consolidated statements of income, as though ASU 2016-09 had been in effect since the beginning of fiscal 2016, instead of reflected in stockholders' equity. The benefit was previously recorded within additional paid-in capital, representing the cumulative windfall tax benefit related to exercises of stock options. With respect to forfeitures, the Company will continue to estimate the number of awards expected to be forfeited in accordance with our existing accounting policy. In April 2015, the FASB issued ASU 2015-03, Interest - Imputation of Interest (Subtopic 835-30), which required 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 Company early adopted this guidance as of July 31, 2016. In connection with the Company's adoption of ASU 2015-03, prior year debt balances have been retrospectively adjusted to include a direct deduction of unamortized debt issuance costs, resulting in a reclassification of $1.3 million of debt issuance costs to long-term debt obligation. Prior to the adoption of ASU 2015-03, the unamortized debt issuance costs were included in other assets on the Company's consolidated balance sheets. Pending In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which supersedes all existing guidance on accounting for leases in ASC Topic 840. This ASU is intended to provide enhanced transparency and comparability by requiring lessees to record right-of-use assets and corresponding lease liabilities on the balance sheet. This ASU will continue to classify leases as either finance or operating, with classification affecting the pattern of expense recognition in the statement of income. This ASU is effective for annual and interim periods within those annual reporting periods beginning after December 15, 2018 and adoption is to be applied with a modified retrospective approach to each prior reporting period presented with various optional practical expedients; however early adoption is permitted. The Company has not determined the potential effects of implementing ASU 2016-02 on the consolidated financial statements. In November 2015, the FASB issued ASU No. 2015-17, Balance Sheet Classification of Deferred Taxes , which requires companies to classify all deferred tax assets and liabilities as non-current on the balance sheet, rather than separating deferred taxes into current and non-current amounts. This ASU is effective for annual and interim periods within those annual reporting periods beginning after December 15, 2016 and can be adopted prospectively or retrospectively; however, early adoption is permitted. The Company’s adoption of ASU 2015-17 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 within those annual reporting periods beginning after December 15, 2015. The Company’s adoption of ASU 2015-02 is not expected to 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 within those annual reporting 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 is currently evaluating the impact of implementing ASU 2014-09 on the consolidated financial statements, as well as evaluating the adoption date and transition alternatives.

Segment Reporting Information [Line Items]
Schedule of revenues by geographic location	14 — 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, operating income and income before income taxes. The segments continue to share similar business models, services and economic characteristics although recent changes in management structure and continued growth in the Company's International region have resulted in the change in the reportable segments. Prior period reportable segment information has been adjusted to reflect the change in the Company's reportable segments. Intercompany income (expense) primarily related to charges for services provided by the U.S. segment.
