Fair Value Disclosures [Abstract] |
Fair Value Measurements | K. Fair Value Measurements We measure certain financial assets and liabilities at fair value. Fair value is defined as an “exit price” which represents the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants as of the measurement date. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in valuing an asset or liability. The accounting guidance requires the use of valuation techniques to measure fair value that maximize the use of observable inputs and minimize the use of unobservable inputs. As a basis for considering such assumptions and inputs, a fair value hierarchy has been established that identifies and prioritizes three levels of inputs to be used in measuring fair value. The three levels of the fair value hierarchy are as follows: Level 1 — Observable inputs such as quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 — Inputs other than the quoted prices in active markets that are observable either directly or indirectly, including: quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active or other inputs that are observable or can be corroborated by observable market data. Level 3 — Unobservable inputs that are supported by little or no market data and require the reporting entity to develop its own assumptions. The following table summarizes the fair value of our assets and liabilities that were accounted for at fair value on a recurring basis as of September 30, 2015 (in thousands):

Cash equivalents, primarily funds held in money market savings instruments, are reported at their current carrying value which approximates fair value due to the short-term nature of these instruments and are included in cash and cash equivalents in our Consolidated Balance Sheets. Fair Value of Other Financial Instruments Fair value guidance requires certain fair value disclosures be presented in both interim and annual reports. The estimated fair value amounts of financial instruments have been determined using available market information and valuation methodologies described below. Deferred Compensation – We hold investments in an irrevocable Rabbi Trust for our deferred compensation plan. These assets include both mutual fund investments and company-owned life insurance policies. Under the plan, participants designate investment options to serve as the basis for measurement of the notional value of their accounts. The fair values of the underlying securities of these funds are based on quoted market prices and are categorized as Level I in the fair value measurement hierarchy. The company-owned life insurance policies are valued at cash surrender value and are therefore categorized as Level 2 in the fair value measurement hierarchy. Industrial Development Revenue Bonds – The fair value of our long-term debt depends primarily on the coupon rate of our industrial development revenue bonds. The carrying value of our long-term debt at September 30, 2015, approximates fair value based on the current coupon rate of the bonds, which is reset weekly. It is classified as a Level 2 input in the fair value measurement hierarchy as there is an active market for the trading of these industrial development revenue bonds. There were no transfers between levels with the fair value measurement hierarchy during Fiscal 2015.

Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information. + References Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 820 -SubTopic 10 -Section 50 -Paragraph 2 -URI http://asc.fasb.org/extlink&oid=36462937&loc=d3e19207-110258 Reference 2: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 825 -SubTopic 10 -Section 50 -Paragraph 30 -URI http://asc.fasb.org/extlink&oid=6957238&loc=d3e14172-108612 Reference 3: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 825 -SubTopic 10 -Section 50 -Paragraph 28 -URI http://asc.fasb.org/extlink&oid=6957238&loc=d3e14064-108612 Reference 4: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 825 -SubTopic 10 -Section 50 -Paragraph 21 -URI http://asc.fasb.org/extlink&oid=49121117&loc=d3e13537-108611 Reference 5: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 825 -SubTopic 10 -Section 50 -Paragraph 16 -URI http://asc.fasb.org/extlink&oid=49121117&loc=d3e13504-108611 Reference 6: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 825 -SubTopic 10 -Section 50 -Paragraph 10 -URI http://asc.fasb.org/extlink&oid=49121117&loc=d3e13433-108611 + Details
