The debt securities held at May 10, 2014, had effective maturities ranging from less than one year to approximately 3 years. The Company did not realize any material gains or losses on its marketable securities during the thirty-six week period ended May 10, 2014.

The Company holds 12 securities that are in an unrealized loss position of approximately $91 thousand at May 10, 2014. The Company has the intent and ability to hold these investments until recovery of fair value or maturity, and does not deem the investments to be impaired on an other than temporary basis. In evaluating whether the securities are deemed to be impaired on an other than temporary basis, the Company considers factors such as the duration and severity of the loss position, the credit worthiness of the investee, the term to maturity and the intent and ability to hold the investments until maturity or until recovery of fair value.

During the twelve week period ended February 15, 2014, the Company’s insurance captive transferred $28.2 million of its marketable securities to a trust account to secure its obligations to an insurance company related to future workers compensation and casualty losses. These securities held by the trust account are included above in total marketable securities.
