At December 30, 2016, available-for-sale securities are recorded in other assets on the Condensed Consolidated Balance Sheets, because the Company does not expect to collect or sell all or a portion of its loans in the next twelve months. As of December 30, 2016, the Company's CPTC loans with a carrying value of $98.1 million were determined to be other-than-temporarily impaired due to credit losses. As a result of this determination, the investment was written down to its estimated fair value of $60.0 million, resulting in an impairment charge of $38.3 million, which includes $0.2 million of other loan related charges. See Note 15, "VPT Loans" for further information on the CPTC impairment. At September 30, 2016, available-for-sale securities are recorded in short-term investments on the Condensed Consolidated Balance Sheets, because the expected contractual maturity dates were less than one year.
