Accounting Policies [Abstract] |
Consolidated Financial Statements Policy [Table Text Block] | Consolidated Condensed Financial Statements— In the opinion of the Company, the accompanying Consolidated Condensed Financial Statements reflect all adjustments necessary to state fairly the Company’s financial position, results of operations and cash flows for the interim periods presented. All such adjustments are of a normal recurring nature. Results for interim periods are not indicative of the results for the entire fiscal year, particularly given the significant seasonality to the Company’s operating cycle. The accompanying Consolidated Condensed Financial Statements should be read in conjunction with the audited Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the fiscal year ended July 31, 2019. Certain information and footnote disclosures, including significant accounting policies, normally included in fiscal year financial statements prepared in accordance with accounting principles generally accepted in the U.S. (“GAAP”) have been condensed or omitted. The Consolidated Condensed Balance Sheet as of July 31, 2019 was derived from audited financial statements.
Use of Estimates | Use of Estimates— The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the balance sheet date and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from those estimates.
New Accounting Pronouncements and Changes in Accounting Principles [Text Block] | Recently Issued Accounting Standards Adopted Standards In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU’) No. 2016-02, “Leases (Topic 842),” which supersedes “Leases (Topic 840).” The standard requires lessees to recognize the assets and liabilities arising from all leases on the balance sheet, including those classified as operating leases under previous accounting guidance, and to disclose key information about leasing arrangements. The standard also allows for an accounting policy election not to recognize on the balance sheet lease assets and liabilities for leases with a term of 12 months or less. Under the new guidance, lessees are required to recognize a lease liability and an ROU asset on their balance sheets, while lessor accounting is largely unchanged. In July 2018, the FASB released ASU No. 2018-11, “Leases (Topic 842): Targeted Improvements” which, among other items, provided an additional and optional transition method. Under this method, an entity initially applies the standard at the adoption date, including the election of certain transition reliefs, and recognizes a cumulative effect adjustment to the opening balance of retained earnings in the period of adoption. The Company adopted ASU No. 2016-02 on August 1, 2019 using the modified retrospective transition method as provided by the standard. In accordance with this transition method, results for reporting periods beginning on August 1, 2019 are presented under the new standard, while prior periods were not adjusted and continue to be reported in accordance with the previously applicable accounting guidance. The Company has elected the package of practical expedients permitted under the transition guidance which allowed the Company to not reassess: (i) whether any existing or expired contracts are or contain leases; (ii) lease classification of any expired or existing leases; or (iii) initial direct costs for any existing leases. The Company has made an accounting policy election to not record leases on the balance sheet with an initial term of 12 months or less. The Company will recognize those lease payments in the Consolidated Condensed Statements of Operations on a straight-line basis over the lease term. Additionally, the Company has elected the practical expedient to not evaluate existing or expired land easements that were not previously accounted for as leases. At adoption, the Company was not able to determine the interest rate implicit in its leases; therefore, for existing operating leases, the lease liability was measured using the Company’s estimated incremental borrowing rate. For existing leases, the incremental borrowing rate used was based on the remaining lease term at the adoption date. For leases with minimum lease payments adjusted periodically for inflation, the lease liability was measured using the minimum lease payments adjusted by the inflation index at the adoption date. On August 1, 2019, as a result of adopting the standard, the Company recorded $225.6 million of operating ROU assets and $258.0 million of related total operating lease liabilities in the Consolidated Condensed Balance Sheet (of which $223.1 million was recorded to operating lease liabilities and $34.9 million was recorded to accounts payable and accrued liabilities). As a result of the adoption, the Company reclassified $32.4 million of unfavorable lease obligations, deferred rent credits and other similar amounts to the operating ROU assets balance, primarily from other long-term liabilities, which reduced the amount recognized as operating ROU assets to $225.6 million. The adoption of the new lease standard did not result in a cumulative effect adjustment to beginning retained earnings, and did not materially affect the Company’s Consolidated Condensed Statement of Operations or Consolidated Condensed Statement of Cash Flows for the three months ended October 31, 2019. The Company’s Canyons finance lease was not affected by the implementation of this standard as the arrangement is classified and recorded as a finance lease arrangement under both the previous and new accounting guidance.
