RECENT ACCOUNTING PRONOUNCEMENTS (Policies)	Apr. 30, 2020
Accounting Policies [Abstract]
Basis of Accounting	The accompanying condensed consolidated financial statements have been prepared by the Company in accordance with accounting principles generally accepted in the United States of America for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all the information and footnotes required by generally accepted accounting principles ("U.S. GAAP") for complete financial statements. In the opinion of management, all adjustments (consisting of a normal recurring nature) considered necessary for fair presentation have been included. These unaudited condensed consolidated financial statements should be read in conjunction with the audited financial statements and related notes for the year ended July 31, 2019, which are contained in the Company's Annual Report on Form 10-K filed with the Securities and Exchange Commission on October 15, 2019, as amended by Amendment No. 1 filed on November 26, 2019. The results for the three and nine months ended April 30, 2020 are not necessarily indicative of the results to be expected for the full fiscal year. The year-end condensed consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America.
Consolidation	All significant intercompany transactions and balances have been eliminated in consolidation.
Recent Accounting Pronouncements	RECENT ACCOUNTING PRONOUNCEMENTS Adoption of New Accounting Standards In February 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-02, Leases (Topic 842), which supersedes the previous guidance for lease accounting, Leases (Topic 840). ASC 842 requires lessees to recognize leases on their balance sheets (through right-of-use ("ROU") assets and lease liabilities). The Company adopted the provisions of ASC 842 on August 1, 2019, using the modified retrospective approach and the option presented under ASU 2018-11, Leases (Topic 842), to transition only active leases as of the August 1, 2019 adoption date, with a cumulative effect adjustment recorded as of that date. All comparative periods prior to August 1, 2019 retain the financial reporting and disclosure requirements of ASC 840. The Company elected to utilize the transition package of practical expedients permitted under ASC 842, which, among other things, allowed the Company to carry forward the historical lease classification. Additionally, the Company made an accounting policy election to exempt short-term leases (with an initial term of 12 months or less) from the provisions of ASC 842, which resulted in recognition of the related lease payments on a straight-line basis over the lease term, consistent with prior treatment under ASC 840. The Company did not elect the "hindsight" practical expedient when determining the lease terms under ASC 842. Adoption of ASC 842 resulted in the recording of ROU operating lease assets and corresponding operating lease liabilities of $51.1 million and $53.1 million, respectively, as of August 1, 2019. The difference between the ROU assets and the lease liabilities represents the existing deferred rent balance (under ASC 840), which was reduced to zero, net of prepaids, upon adoption of ASC 842 on August 1, 2019. The adoption of ASC 842 did not materially impact the Company's net earnings and had no impact on its cash flows. The Company's current lease arrangements expire through 2030. In June 2018, the FASB issued ASU 2018-07, Compensation-Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting. This standard was created to simplify the accounting for share-based payments to nonemployees and provides guidance on how to account for share-based payment awards issued in transactions in which a grantor acquires goods or services to be used or consumed in the grantor's own operations. The amendments in ASU 2018-07 are effective for the Company's 2020 fiscal year. The adoption of the accounting standard did not have a material impact on the Company's financial statements. Accounting Standards Issued and Not Yet Implemented In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Loses on Financial Instruments, an accounting standard update that requires measurement and recognition of expected credit losses for financial instruments, including trade receivables, based on historical experience, current conditions and reasonable and supportable forecasts that affect the collectability of the reported amount. The accounting standard update will be effective for the Company beginning in the first quarter of fiscal year 2024 on a modified retrospective basis which requires a cumulative effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. The Company is currently evaluating the impact of this accounting standard update on its consolidated financial statements. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement. ASU 2018-13 modifies the disclosure requirements on fair value measurements. The amendments in ASU 2018-13 are effective for the Company's fiscal year 2021, except that the standard permits an entity to early adopt any removed or modified disclosures upon issuance of ASU 2018-13 and delay adoption of the additional disclosures until the effective date. The Company does not expect that the full adoption of this standard will have a material impact on the Company's consolidated financial statements. In August 2018, the FASB issued ASU 2018-14, Compensation-Retirement Benefits-Defined Benefit Plans-General (Subtopic 715-20): Disclosure Framework-Changes to the Disclosure Requirements for Defined Benefit Plans. ASU 2018-14 modifies the disclosure requirements for employers that sponsor defined benefit pension and other post-retirement plans. The amendments in ASU 2018-14 are effective for the Company's fiscal year 2021. The Company does not expect that the adoption of this standard will have a material impact on the Company's consolidated financial statements. In August 2018, the FASB issued ASU 2018-15, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract, (a consensus of the FASB Emerging Issues Task Force) to align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal use software license). The amendments in ASU 2018-15 are effective for the Company's first quarter of fiscal year 2021. The Company is currently evaluating the potential impact of this new guidance. In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, which amends the existing guidance relating to the accounting for income taxes. This ASU is intended to simplify the accounting for income taxes by removing certain exceptions to the general principles of accounting for income taxes and to improve the consistent application of U.S. GAAP for other areas of accounting for income taxes by clarifying and amending existing guidance. The new guidance is effective for the Company's first quarter of fiscal year 2022. The Company does not expect that the adoption of this new guidance will have a material impact on its consolidated financial statements. In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which is intended to provide temporary optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships and other transactions affected by the discontinuation of the London Interbank Offered Rate, known as LIBOR, or by another reference rate expected to be discontinued. This optional guidance is effective beginning on March 12, 2020, and the Company may elect to apply the amendments prospectively through December 31, 2022. The Company is currently evaluating the impact this guidance may have on its consolidated financial statements.
Fair Value of Financial Instruments	ASC 820 provides that fair value is an exit price, representing the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants based on the highest and best use of the asset or liability. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. ASC 820 requires the Company to use valuation techniques to measure fair value that maximize the use of observable inputs and minimize the use of unobservable inputs. These inputs are prioritized as follows: Level 1: Observable inputs such as quoted prices for identical assets or liabilities in active markets Level 2: Other inputs that are observable directly or indirectly, such as quoted prices for similar assets or liabilities or market-corroborated inputs Level 3: Unobservable inputs for which there is little or no market data and which require the Company to develop its own assumptions about how market participants would price the assets or liabilities The carrying value of cash and cash equivalents, accounts receivable, restricted cash, accounts payable, current liabilities and the revolving line of credit approximate fair value because of the short maturity of these instruments. We believe that the carrying value of our long-term debt approximates fair value because the stated interest rates of this debt is consistent with current market rates. The carrying value of capital lease obligations approximates fair value, as estimated by using discounted future cash flows based on the Company's current incremental borrowing rates for similar types of borrowing arrangements.
