Fair Value Measurements

NOTE K—FAIR VALUE MEASUREMENTS

The Company utilizes the hierarchy of fair value measurement to classify certain of its assets and liabilities based upon the following definitions:

Level 1- Investments with quoted prices in active markets for identical assets or liabilities. The Company'scash equivalents are invested in money market funds, mutual funds and United States Treasury instruments. The Company's mutual fund investment assets represent contributions made and invested on behalf of the Company's named executive officers in a supplementary employee retirement plan.

Level 2- Investments with observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. The Company has no Level 2 assets or liabilities.

Level 3- Investments with unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. The Company has no Level 3 assets or liabilities.

The following table summarizes the fair values of assets that are recorded in the Company's unaudited condensed consolidated financial statements as of October 31, 2011 and April 30, 2011 at fair value on a recurring basis (in thousands):
