Fair Value Disclosures [Abstract]
Fair Value Disclosures [Text Block]	Note 2 - Fair Value Measurements We measure fair values using unadjusted quoted prices in active markets (Level 1 inputs), quoted prices for similar instruments in active or inactive markets, or other directly-observable factors (Level 2 inputs), or inputs that are unobservable and significant to the fair value measurement (Level 3 inputs). Our financial instruments consist primarily of cash, trade receivables and payables, and our credit facility. The carrying values of cash and trade receivables and payables are considered to be representative of their respective fair values. Our credit facility, which was entered into effective July 24, 2013 (and most recently amended September 26, 2013), bears interest at floating market interest rates; therefore, we believe the fair value of amounts borrowed approximates the carrying value. At September 30, 2013, June 30, 2013 and September 30, 2012, no other material financial assets or liabilities were measured at fair value.

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. 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.
