3. Fair Value Measurements
We determine the appropriate classification of debt investment securities at the time of purchase and re-evaluate such designation as of each balance sheet date. Our investment portfolio consists of money market funds, corporate debt investments, asset-backed securities, government-sponsored enterprises, and state and municipal obligations. All highly liquid investments with an original maturity of three months or less when purchased are considered to be cash equivalents. All cash equivalents are carried at cost, which approximates fair value. Our marketable securities are classified as available-for-sale and are reported at fair value with unrealized gains and losses, net of tax, reported in stockholders’ equity as a component of accumulated other comprehensive income or loss. The amortization of premiums and accretion of discounts to maturity are computed under the effective interest method and are included in interest income. Interest on securities is recorded as earned and is also included in interest income. Any realized gains or losses would be shown in the accompanying consolidated statements of operations in other income or expense. We provide fair value measurement disclosures of its available for sale securities in accordance with one of three levels of fair value measurement.
Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is a market-based measurement, not an entity-specific measurement. A fair value hierarchy enables the reader of the financial statements to assess the inputs used to develop fair value measurements by establishing a hierarchy for ranking the quality and reliability of the information used to determine fair values. Assets and liabilities carried at fair value will be classified and disclosed in one of the following three categories:
Level 1: Quoted market prices in active markets for identical
assets or liabilities.
Our financial assets and liabilities that are measured at fair value on a recurring basis as of April 30, 2012 are as follows:
The following table sets forth the activity of our Level 1 investments. Investments are classified as Level 1 when there is a current active market:
Based on additional information, we have made a revision to reclassify $5.6 million of investments from Level 2 to Level 1 as of January 31, 2012. Management believes the revision is immaterial to the financial statements.
The following table sets forth a reconciliation of assets measured at fair value on a recurring basis with the use of significant unobservable inputs (Level 3) for the three months ended April 30, 2012:
