Marketable Securities [Abstract] |
Marketable Securities | Marketable Securities At June 1, 2013, the Company has investments in municipal bonds of $41.7 million; $29.8 million is current and $11.9 million is non-current. The Company’s wholly owned insurance subsidiary, Prism Assurance, Ltd. (Prism), holds $12.3 million of the municipal bonds. Prism insures a portion of the Company’s workers’ compensation, general liability and automobile liability risks using reinsurance agreements to meet statutory requirements. The reinsurance carrier requires Prism to maintain fixed-maturity investments, which are generally high-quality municipal bonds, for the purpose of providing collateral for Prism’s obligations under the reinsurance agreement. All of the Company’s fixed maturity investments are classified as “available-for-sale,” are carried at fair value and are reported as short-term available for sale securities or available for sale securities in the consolidated balance sheet. The amortized cost, gross unrealized gains and losses, and estimated fair values of investments available for sale at June 1, 2013 and March 2, 2013, are as follows:
(In thousands) | Amortized Cost |  | Gross Unrealized Gains |  | Gross Unrealized Losses |  | Estimated Fair Value
June 1, 2013 |  |  |  |  |  |  |
Municipal bonds | $ | 41,852 |  |  | $ | 91 |  |  | $ | (286 | ) |  | $ | 41,657 |
Total investments | $ | 41,852 |  |  | $ | 91 |  |  | $ | (286 | ) |  | $ | 41,657 |
March 2, 2013 |  |  |  |  |  |  |
Municipal bonds | $ | 38,927 |  |  | $ | 127 |  |  | $ | (240 | ) |  | $ | 38,814 |
Total investments | $ | 38,927 |  |  | $ | 127 |  |  | $ | (240 | ) |  | $ | 38,814 |
The Company tests for other than temporary losses on a quarterly basis and considers the unrealized losses indicated above to be temporary in nature. The Company intends to hold the investments until it can recover the full principal amount, and has the ability to do so based on other sources of liquidity. The Company expects such recoveries to occur prior to the contractual maturities. The following table presents the length of time that available-for-sale securities were in continuous unrealized loss positions, but were not deemed to be other than temporarily impaired, as of June 1, 2013:
| Less Than 12 Months |  | Greater Than or Equal to 12 Months |  | Total
(In thousands) | Fair Value |  | Unrealized Losses |  | Fair Value |  | Unrealized Losses |  | Fair Value |  | Unrealized Losses
Municipal bonds | $ | 18,506 |  |  | $ | (94 | ) |  | $ | 1,058 |  |  | $ | (192 | ) |  | $ | 19,564 |  |  | $ | (286 | )
Total investments | $ | 18,506 |  |  | $ | (94 | ) |  | $ | 1,058 |  |  | $ | (192 | ) |  | $ | 19,564 |  |  | $ | (286 | )
The amortized cost and estimated fair values of investments at June 1, 2013, by contractual maturity, are shown below. Expected maturities may differ from contractual maturities as borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.
(In thousands) | Amortized Cost |  | Estimated Market Value
Due within one year | $ | 29,777 |  |  | $ | 29,775 |
