Fair Value Disclosures [Abstract] |
Fair Value Measurements | Fair Value Measurements The Company accounts for financial assets and liabilities in accordance with accounting standards that define fair value and establish a framework for measuring fair value. The hierarchy prioritizes the inputs into three broad levels. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument. Level 3 inputs are unobservable inputs based on the Company’s assumptions used to measure assets and liabilities at fair value. A financial asset’s or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement. Financial assets measured at fair value as of December 1, 2012 and March 3, 2012, are summarized below:

Cash equivalents Cash equivalents include highly liquid investments with an original maturity of three months or less, and consist primarily of money market funds. The cash equivalents are held at fair value based on quoted market prices, which approximates stated cost. Short-term marketable securities available for sale The Company has short-term marketable securities available for sale of $25.2 million as of December 1, 2012, consisting of municipal bonds. The Company classifies these short-term marketable securities as “available-for-sale,” and they are carried at fair market value based on market prices from recent trades of similar securities. Marketable securities available for sale The Company has $10.4 million of marketable securities available for sale, consisting of municipal bonds. All of the Company’s fixed maturity investments are classified as “available-for-sale,” are carried at fair value and are reported as marketable securities available for sale in the consolidated balance sheet. These investments are held at fair value based on prices from recent trades of similar securities. Restricted investments The Company has $12.4 million of current restricted investments consisting of money market funds that were required to be made available to cover our exposure for letters of credit outside of our revolving credit facility. The Company has $14.3 million of long-term restricted investments consisting of money market funds, which are short-term in nature but are restricted for future investment in the Company’s architectural glass fabrication facility in Utah, and storefront and entrance business in Michigan, and are, therefore, classified as long term. The restricted investments are held at fair value based on quoted market prices, which approximate stated cost. Mutual fund investments The Company has $0.2 million of mutual fund investments as a long-term funding source for the deferred compensation plan. The mutual fund investments are recorded at estimated fair value, based on quoted market prices, and are included in other non-current assets in the consolidated balance sheet.
