Fair Value Disclosures [Abstract]
Fair Value Measurements	FAIR VALUE MEASUREMENTS Fair value is defined 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 inputs used to measure fair value are prioritized into categories based on the lowest level of input that is significant to the fair value measurement. The categories in the fair value hierarchy are as follows: Level 1: Quoted market prices in active markets for identical assets or liabilities. Level 2: Observable market-based inputs for similar assets or liabilities or valuation models whose inputs are observable, directly or indirectly. Level 3: Unobservable inputs. Cash equivalents of $2,402,000 and $3,814,000 as of October 31, 2017 and July 31, 2017, respectively, were classified as Level 1. These cash instruments are primarily money market mutual funds and are included in cash and cash equivalents on the unaudited Condensed Consolidated Balance Sheet. Short-term investments included U.S. Treasury securities and certificates of deposit. We intend and have the ability to hold our short-term investments to maturity; therefore, these investments were reported at amortized cost, which approximated fair value as of October 31, 2017 and July 31, 2017. Accounts receivable and accounts payable balances approximated their fair values at October 31, 2017 and July 31, 2017 due to the short maturity and nature of those balances. Notes payable are reported at the face amount of future maturities. The estimated fair value of notes payable, including current maturities, was $9,645,000 and $13,001,000 as of October 31, 2017 and July 31, 2017, respectively. Our debt does not trade on a daily basis in an active market, therefore the fair value estimate is based on market observable borrowing rates currently available for debt with similar terms and average maturities and is classified as Level 2. We apply fair value techniques on at least an annual basis associated with: (1) valuing potential impairment loss related to goodwill, trademarks and other indefinite-lived intangible assets and (2) valuing potential impairment loss related to long-lived assets. See Note 5 for further information about goodwill and other intangible assets.
