The debt securities held at November 19, 2016, had effective maturities ranging from less than one year to approximately three years. The Company did not realize any material gains or losses on its marketable securities during the twelve week period ended November 19, 2016.

The Company holds 87 securities that are in an unrealized loss position of approximately $318 thousand at November 19, 2016. 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.

Included above in total marketable securities are $84.4 million of marketable securities transferred by the Company’s insurance captive to a trust account to secure its obligations to an insurance company related to future workers’ compensation and casualty losses.
