FAIR VALUE MEASUREMENTS
We make fair value determinations by applying the following hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement:

Level 1 - inputs are based upon quoted prices for identical instruments traded in active markets;
Level 2 - inputs are based upon quoted prices for similar instruments in active markets and model-based valuation techniques for which all significant assumptions are observable in the market; and
Level 3 - inputs are generally unobservable and typically reflect management’s estimates of assumptions that market participants would use in pricing the asset or liability. These include discounted cash flow models and similar valuation techniques.
Recurring fair value measurements and financial instruments - The carrying amounts reported for financial instruments, including cash and cash equivalents, short-term investments, contracts receivable and accounts payable, approximate their fair values.

Assets held for sale - We measure and record assets held for sale at the lower of their carrying amount or fair value less costs to sell. The determination of fair value generally requires the use of significant judgments. See Note 2 for further discussion of our assets held for sale and their associated fair value measurements.
