See Note 16, "VPT Loans and Securities" for more information on CPTC, Delray Radiation Therapy Center ("DRTC") and Georgia Proton Therapy Center ("GPTC") Securities.

As of September 29, 2017, the available-for-sale securities are recorded in other assets on the Consolidated Balance Sheets, because their maturity dates are greater than one year or the Company does not intend to collect or sell all or a portion of its loans or securities in the next twelve months. In the fiscal year 2017, the Company's Original CPTC Loans 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 $47.4 million, resulting in impairment charges of $51.4 million. As of September 29, 2017, the Company believes recoverability of the entire amortized cost basis of all of its available-for-sale securities is probable. See Note 16, "VPT Loans and Securities" for further information on CPTC impairment charges during fiscal year 2017.

As of September 30, 2016, the available-for-sale securities are recorded in short-term investments because their maturity dates were less than one year.
