Accounting Policies [Abstract] |
Consolidated Condensed Financial Statements | 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, 2020. 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, 2020 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.
Fair Value of Financial Instruments | Fair Value of Financial Instruments — The recorded amounts for cash and cash equivalents, restricted cash, receivables, other current assets and accounts payable and accrued liabilities approximate fair value due to their short-term nature. The fair value of amounts outstanding under the Company’s credit agreements and the Employee Housing Bonds (as defined in Note 5, Long-Term Debt) approximate book value due to the variable nature of the interest rate associated with the debt. The estimated fair value of the 6.25% Notes (as defined in Note 5, Long-Term Debt) is based on quoted market prices (a Level 2 input). The estimated fair value of the EPR Secured Notes and EB-5 Development Notes (each as defined in Note 5, Long-Term Debt), have been estimated using analyses based on current borrowing rates for debt with similar remaining maturities and ratings (a Level 2 input). The carrying values, including any unamortized premium or discount, and estimated fair values of the 6.25% Notes, EPR Secured Notes and EB-5 Development Notes as of October 31, 2020 are presented below (in thousands):
