Recent Accounting Pronouncements and Supplemental Information [Abstract]
Recent Accounting Pronouncements	Recently Adopted Accounting Pronouncements: In March 2017, the Financial Accounting Standards Board (“FASB)” issued guidance that will shorten the amortization period for certain callable debt securities held at a premium to the earliest call date. This guidance does not require an accounting change for securities held at a discount. The guidance was effective for our first quarter of fiscal year 2020. The adoption did not have a material effect on our condensed consolidated financial statements. In February 2016, the FASB issued guidance that revises the accounting for leases. The guidance is intended to improve financial reporting of leasing transactions by requiring lessees to record right-of-use assets and corresponding lease liabilities on the balance sheet. Leases will continue to be classified as either operating or finance leases, with the classification affecting the pattern of expense recognition in the statement of income. The guidance also requires additional disclosures to help investors and other financial statement users better understand the amount, timing, and uncertainty of cash flows arising from leases. In January 2018, the FASB issued additional guidance for land easements which permits entities to forgo the evaluation of existing land easement arrangements to determine if they contain a lease. New land easement arrangements, or modifications to existing arrangements, after the adoption of the lease standard will be evaluated to determine if they meet the definition of a lease. In July 2018, the FASB amended the new standard to clarify certain aspects of the guidance, and they also issued another new standard in July 2018 that allows the option to apply the transition provisions at the adoption date instead of at the earliest comparative period in the condensed consolidated financial statements. In March 2019, the FASB issued clarifying guidance regarding interim transition disclosures. We adopted this lease guidance as of the beginning of our fiscal year 2020. We have assessed our portfolio of leases and compiled a central repository of leases, recording a right-of-use asset and a lease liability for all leases with a lease term of greater than twelve months. All changes required by the new standard, including accounting policies, controls, and disclosures, have been identified and implemented. See Note 6 - Leases in the Notes to Condensed Consolidated Financial Statements for additional information. Recently Issued Accounting Pronouncements Not Yet Adopted: In August 2018, the FASB issued guidance on a customer’s accounting for implementation, set-up, and other upfront costs incurred in a cloud computing arrangement that is hosted by the vendor. Under the new guidance, customers will apply the same criteria for capitalizing implementation costs as they would for an arrangement that has a software license. The guidance is effective for our first quarter of fiscal year 2021 with early adoption permitted. Entities can choose to adopt the guidance prospectively to eligible costs incurred on or after the date this guidance is first applied or retrospectively. We have not yet determined the effect of this guidance on our condensed consolidated financial statements. In August 2018, the FASB issued guidance which changes the fair value measurement disclosure requirements. The guidance modifies and removes certain disclosures related to the fair value hierarchy, and adds new disclosure requirements such as disclosing the changes in unrealized gains and losses included in other comprehensive income for recurring Level 3 fair value measurements and disclosing the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. The guidance is effective for our first quarter of fiscal year 2021 with early adoption permitted and should be applied retrospectively except for certain disclosures. We have not yet determined the effect of this guidance on our condensed consolidated financial statements. In June 2016, the FASB issued guidance on the measurement of credit losses on financial instruments. Under the guidance, an entity recognizes as an allowance its estimate of expected credit losses, which the FASB believes will result in more timely recognition of such losses. The guidance is also intended to reduce the complexity by decreasing the number of credit impairment models that entities use to account for debt instruments. In May 2019, the FASB amended the new standard to allow entities to elect the fair value option on certain financial instruments that were previously recorded at amortized cost. The guidance is effective for our first quarter of fiscal year 2021 with early adoption in our fiscal year 2020 permitted. We have not yet determined the effect of this guidance on our condensed consolidated financial statements.
Goodwill	Goodwill represents the difference between the purchase price and the related underlying tangible and intangible net asset fair values resulting from business acquisitions. Goodwill is assigned to and the fair value is tested at the reporting unit level. Annually, or if conditions indicate an earlier review is necessary, we may assess qualitative factors to determine if it is more likely than not that the fair value is less than its carrying amount. We also have the option to bypass the qualitative assessment and proceed directly to performing the quantitative goodwill impairment test which compares the carrying value of the reporting unit to the reporting unit’s fair value to identify impairment. Under the quantitative assessment, if the fair value of the reporting unit is less than the carrying value, goodwill is written down to its fair value. The fair value is established primarily using a discounted cash flow analysis and secondarily a market approach utilizing current industry information. The calculation of the fair value of the reporting unit considers current market conditions existing at the assessment date.
Impairment Or Disposal Of Intangible Assets	Intangible assets are reviewed for impairment when events or circumstances indicate that the carrying value may not be recoverable over the remaining lives of the assets.
Intangible Assets	Capitalized software is stated at cost less accumulated amortization and is amortized using the straight-line method. During the software application development stage, capitalized costs include external consulting costs, cost of software licenses, and internal payroll and payroll-related costs for employees who are directly associated with a software project. Upgrades and enhancements are capitalized if they result in added functionality which enable the software to perform tasks it was previously incapable of performing. Software maintenance, training, data conversion, and business process re-engineering costs are expensed in the period in which they are incurred. Trade names and non-compete agreements are amortized on a straight-line basis over their estimated useful lives. Capitalized customer relationships are amortized based on estimated attrition rates of customers.
Notes Receivables and Trade Accounts Receivable	Notes Receivable and Trade Accounts Receivable: Notes receivable and trade accounts receivable are recorded per the terms of the agreement or sale, and accrued interest is recognized when earned. We determine on a case-by-case basis the cessation of accruing interest, the resumption of accruing interest, the method of recording payments received on nonaccrual receivables, and the delinquency status for our limited number of notes receivable. Our policy for estimating the allowance for credit losses on trade accounts receivable and notes receivable includes analysis of such items as aging, credit worthiness, payment history, and historical bad debt experience. Management uses these specific analyses in conjunction with an evaluation of the general economic and market conditions to determine the final allowance for credit losses on the trade accounts receivable and notes receivable. Trade accounts receivable and notes receivable are written off after exhaustive collection efforts occur and the receivable is deemed uncollectible. Our limited amount of notes receivable allows management to monitor the risks, credit quality indicators, collectability, and probability of impairment on an individual basis. Adjustments to the allowance for credit losses are recorded in selling and administrative expenses. Customary terms require payment within 30 days, with terms beyond 30 days being considered extended.
Non-operating Income and Expense, net	The non-operating income (expense), net line item includes the impact of such items as fair value adjustments on Supplemental Employee Retirement Plan (“SERP”) investments, amortization of actuarial income, bank charges, and other miscellaneous non-operating income and expense items that are not directly related to operations. The gain or loss on SERP investments is offset by a change in the SERP liability that is recognized in selling and administrative expenses.
