Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Accounting standards define fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value hierarchy prioritizes the inputs to valuation techniques used to measure fair value. An asset’s or liability’s level is based on the lowest level of input that is significant to the fair value measurement. Assets and liabilities carried at fair value are valued and disclosed in one of the following three levels of the valuation hierarchy: Level 1: Quoted market prices in active markets for identical assets or liabilities. Level 2: Observable market-based inputs or unobservable inputs that are corroborated by market data. Level 3: Unobservable inputs reflecting the reporting entity’s own assumptions. At October 31, 2018 and October 31, 2017, the carrying value of cash and cash equivalents, accounts receivable, prepaid expenses and other current assets, lines of credit, accounts payable and other current liabilities approximate fair value due to the short-term nature of such instruments and the ability to obtain financing on similar terms. The carrying value of our revolving credit facility and term loans approximates fair value which is estimated based on current market rates (Level 2). The Company did not have any derivative assets or liabilities that may include interest rate swaps, cross currency swaps or foreign currency forward contracts as of October 31, 2018 and October 31, 2017. Nonrecurring fair value measurements On a nonrecurring basis, the Company uses fair value measures when analyzing asset impairment. Generally, assets are recorded at fair value on a nonrecurring basis as a result of impairment charges. In fiscal 2018, we recorded $24.4 million of impairment charge during the second fiscal quarter related to the intangible assets acquired from Recombine Inc. as the cash flows expected to be generated by this asset group over its estimated remaining life were not sufficient to recover its carrying value. Our valuation included unobservable Level 3 inputs and was based on expected sales proceeds and discounted cash flows. The fair value of these intangible assets determined at the end of the second fiscal quarter was $0. In addition, the Company uses fair value measures when determining assets and liabilities acquired in an acquisition as described in Note 2. Acquisitions which are considered a Level 3 measurement.
