Fair Value Measurements	Jul. 31, 2018
Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements At July 31, 2018 and October 31, 2017, the carrying value of cash and cash equivalents, accounts receivable, prepaid expense 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. Assets and liabilities are measured and reported at fair value per related accounting standards that 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. We believe that the balances of our revolving credit agreement and term loans approximated their fair values at July 31, 2018 and October 31, 2017 and are categorized as Level 2 of the fair value hierarchy. The Company did not have any derivative assets or liabilities that may include interest rate swaps, cross currency swaps or foreign currency forward contracts at July 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 the second quarter of fiscal 2018, we recorded $24.4 million of impairment charge 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. The fair value of these intangible assets determined at April 30, 2018 was $0. Our valuation included unobservable Level 3 inputs and was based on expected sales proceeds and discounted cash flows as of April 30, 2018. There was no significant asset impairment for the three months ended July 31, 2018.
