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 August 25, 2011 (and most recently amended August 29, 2012 and November 12, 2012), bears interest at floating market interest rates; therefore, we believe the fair value of amounts borrowed approximates the carrying value.  At September 30, 2012, June 30, 2012 and September 30, 2011, no other material assets or liabilities were measured at fair value.
