Actual results could differ from those estimates. Significant estimates include accrued sales and use taxes, the liability for incurred but unreported claims under various partially self-insured polices, allowance for doubtful accounts, goodwill impairment analysis, valuation of share-based compensation and accounting for business combinations. Actual results may may Trade receivables Trade receivables are carried at the original invoice amount less an estimate made for doubtful receivables based on a review of all outstanding amounts.

Inventories are stated at the lower of cost ( first first July 31, 2021 October 31, 2020 Fair Value Measurements The Financial Accounting Standard Board's (the “FASB”) standard on fair value measurements establishes a fair value hierarchy that requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. A financial instrument’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. This standard establishes three may Level 1 Level 2 1 Level 3 Deferred financing costs Deferred financing costs representing third Debt issuance costs, including any original issue discounts, related to term loans or senior notes are reflected as a direct deduction from the carrying amount of the long-term debt liability that is included in long term debt, net of discount for deferred financing costs in the accompanying consolidated balance sheets.

Expenditures for additions and betterments are capitalized. Expenditures for maintenance and repairs are charged to expense as incurred; however, maintenance and repairs that improve or extend the life of existing assets are capitalized. The carrying amount of assets disposed of and the related accumulated depreciation are eliminated from the accounts in the year of disposal. Gains or losses from property and equipment disposals are recognized in the year of disposal. Property, plant and equipment is depreciated using the straight-line method over the following estimated useful lives: In Years Buildings and improvements 15 to 40 Capital lease assets—buildings 40 Furniture and office equipment 2 to 7 Machinery and equipment 3 to 25 Transportation equipment 3 to 7 Intangible assets Intangible assets are recorded at cost or their estimated fair value (when acquired through a business combination) less accumulated amortization (if finite-lived).

The Company recognizes revenue from these businesses when all of the following criteria are met: (a) persuasive evidence of an arrangement exists, (b) the service has been performed or delivery has occurred, (c) the price is fixed or determinable, and (d) collectability is reasonably assured. The Company’s delivery terms for replacement part sales are FOB shipping point. The Company imposes and collects sales taxes concurrent with its revenue-producing transactions with customers and remits those taxes to the various governmental authorities as prescribed by the taxing jurisdictions in which it operates. The Company presents such taxes in its consolidated statement of operations on a net basis.

Fair Value Measurement The carrying amounts of the Company's cash and cash equivalents, accounts receivable, accounts payable and current accrued liabilities approximate their fair value due to the short-term maturity of these instruments. The Company’s outstanding obligations on its ABL credit facility are deemed to be at fair value as the interest rates on these debt obligations are variable and consistent with prevailing rates.
