Fair Value of Financial Instruments | 3 Months Ended
--- | ---
Jul. 29, 2012
Fair Value of Financial Instruments | 9. Fair Value of Financial Instruments ASC Topic 820 establishes a fair value hierarchy that distinguishes between assumptions based on market data (observable inputs) and the company’s assumptions (unobservable inputs). Determining where an asset or liability falls within that hierarchy depends on the lowest level input that is significant to the fair value measurement as a whole. An adjustment to the pricing method used within either level 1 or level 2 inputs could generate a fair value measurement that effectively falls in a lower level in the hierarchy. The hierarchy consists of three broad levels as follows: Level 1 – Quoted market prices in active markets for identical assets or liabilities; Level 2 – Inputs other than level 1 inputs that are either directly or indirectly observable, and Level 3 – Unobservable inputs developed using the company’s estimates and assumptions, which reflect those that market participants would use. The following table presents information about assets and liabilities measured at fair value on a recurring basis:

The determination of where an asset or liability falls in the hierarchy requires significant judgment. We evaluate our hierarchy disclosures each quarter based on various factors and it is possible that an asset or liability may be classified differently from quarter to quarter. However, we expect that changes in classifications between different levels will be rare. Short-term investments include short-term bond funds and deposit accounts that have maturities of less than one year. Our short-term bond funds are classified as available-for-sale and their unrealized gains or losses are included in other comprehensive income. Our short-term bond funds were recorded at their fair value of $5.2 million and $5.1 million at July 29, 2012 and April 29, 2012, respectively. Our short-term bond funds had unrealized gains totaling $49,000 and $16,000 at July 29, 2012 and April 29, 2012. At July 29, 2012 and April 29, 2012, the fair value of our short-term bond funds approximated its cost basis. The carrying amount of cash and cash equivalents, short-term investments that pertain to interest bearing deposit accounts, accounts receivable, other current assets, accounts payable and accrued expenses approximates fair value because of the short maturity of these financial instruments.
