FAIR VALUE DISCLOSURES
FAIR VALUE DISCLOSURES
We account for non-recurring fair value measurements of our non-financial assets and liabilities in accordance with ASC 820-10 Fair Value Measurement ("ASC 820"). This guidance defines fair value, establishes a framework for measuring fair value and addresses required disclosures about fair value measurements. This standard establishes a three-level hierarchy for fair value measurements based upon the significant inputs used to determine fair value. Observable inputs are those which are obtained from market participants external to the company while unobservable inputs are generally developed internally, utilizing management’s estimates, assumptions and specific knowledge of the assets/liabilities and related markets. The three levels are defined as follows:
 
Level 1 — Valuation is based on quoted prices in active markets for identical assets and liabilities.
Level 2 — Valuation is determined from quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar instruments in markets that are not active, or by model-based techniques in which all significant inputs are observable in the market.
Level 3 — Valuation is derived from model-based techniques in which at least one significant input is unobservable and based on the company’s own estimates about the assumptions that market participants would use to value the asset or liability.
Financial Instruments: The fair value of our fixed-rate debt is derived from quoted market prices by independent dealers (level 2 inputs as per the discussion above) and is as follows (in thousands):

Due to the short-term nature of other financial assets and liabilities, including our Loans payable and other borrowings, we consider the carrying amounts of our other short-term financial instruments to approximate fair value.
