​ The debt securities held at November 19, 2022, had effective maturities ranging from less than one year to approximately three years. Securities maturing in less than one year totaled $51.8 million and $49.7 million at November 19, 2022 and August 27, 2022, respectively. Securities maturing between one and three years totaled $67.0 million and $62.8 million at November 19, 2022 and August 27, 2022, respectively. At November 19, 2022, the Company held 75 securities that are in an unrealized loss position of approximately $3.6 million. In evaluating whether a credit loss exists for the securities, the Company considers factors such as the 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. An allowance for credit losses was deemed unnecessary given consideration of the factors above. ​ Included above in total available-for-sale marketable debt securities are $102.9 million of marketable debt 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.
