Fair Value Measurements

5. Fair Value Measurements

Financial instruments consist primarily of cash and cash equivalents, accounts receivable, capital lease obligations and debt. As of January 31, 2014 and 2013, the carrying amounts of these instruments approximate their fair values. The estimated fair values have been determined from information obtained from market sources and management estimates.

In determining the fair value of its financial assets and liabilities, the Company uses various valuation approaches. ASC 820, Fair Value Measurements and Disclosures, establishes a hierarchy of inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that observable inputs be used when available. Observable inputs are inputs that market participants would use in pricing the asset or liability based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about the inputs that market participants would use in pricing the asset or liability, and are developed based on the best information available in the circumstances. The fair value hierarchy is broken down into three levels based on the source of inputs as follows:

Level 1—Valuations based on unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access.

 

Level 2—Valuations based on quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active and models for which all significant inputs are observable, either directly or indirectly.

Level 3—Valuations based on inputs that are unobservable and significant to the overall fair value measurement and that are based on management’s best estimate of inputs market participants would use for pricing the asset or liability at the measurement date, including assumptions about risk.

The availability of observable inputs can vary among the various types of financial assets and liabilities. To the extent that the valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for financial statement disclosure purposes, the level in the fair value hierarchy within which the fair value measurement is categorized is based on the lowest level input that is significant to the overall fair value measurement.

The following table summarizes the Company’s fair value hierarchy for its financial assets and liabilities measured at fair value as of January 31, 2014:
