9. FAIR VALUE MEASUREMENT

We utilize a three level hierarchy that defines the assumptions used to measure certain assets and liabilities at fair value.

Cash and cash equivalents, accounts receivable, the current portion of our investment in sales-type leases and notes receivable are not presented in the table below as their carrying value approximates fair value due to their short term nature.  It is impracticable to estimate the fair value of the long-term portion of our investment in sales-type leases and notes receivable as it is comprised of many insignificant balances, customers with different credit profiles and various interest rates.  As of July 31, 2012 our investment in sales-type leases and notes receivable had an approximate 5.5% effective interest rate and a 2 year average maturity.

The fair value of our Revolver as of July 31, 2012 and October 31, 2011 has been calculated based on market borrowing rates available as of July 31, 2012 and October 31, 2011, respectively, for debt with similar terms and maturities. The following table provides the fair value measurement information about the Company’s long-term debt.
