CPTC Loans	CPTC LOANS In September 2011, ORIX and the Company, through its Swiss subsidiary, committed to loan up to $165.3 million (“Tranche A loan”) to CPTC to fund the development, construction and initial operations of the Scripps Proton Therapy Center. ORIX is the loan agent for this facility and, along with CPTC and Scripps, has budgetary approval authority for the Scripps Proton Therapy Center. The Company’s maximum loan commitment under the Tranche A loan was $115.3 million, reflecting the Company’s pro rata share of 69.75% of the obligation to fund the initial distribution and subsequent advances. In June 2014, the Company, through its Swiss subsidiary, entered into a series of agreements, including amending certain terms of the original loan agreement, pursuant to which J.P. Morgan assumed $45.0 million of the Company’s original maximum commitment of $115.3 million, reducing the Company’s maximum commitment under the Tranche A loan to $70.3 million. Pursuant to these agreements, J.P. Morgan purchased $38.1 million of the Company’s outstanding Tranche A loan at par value and was obligated to fund up to an additional $6.9 million of the remaining Tranche A loan commitment. Through these agreements, the Company’s Swiss subsidiary also increased its individual loan commitment by $10.0 million (“Tranche B loan”) and as a result, the Company’s maximum loan commitment under the Tranche A and Tranche B loans (collectively, referred to as the “CPTC Loans”) is $80.3 million reflecting the Company’s pro rata share of 45.8% of the total obligation to fund CPTC of $175.3 million. As of April 3, 2015, the Company had loaned $70.1 million of its $70.3 million commitment under the Tranche A loan. The Company intends to sell all or a portion of its participation in its Tranche A loan before the maturity date. Upon the sale of all or a portion of the Tranche A loan, the Company will not be required to make further loan advances for the portion of the loan that is sold. As of April 3, 2015, the Company had loaned $9.9 million of its $10.0 million commitment under the Tranche B loan. The amounts loaned under the Tranche A and Tranche B loans include accrued interest. The CPTC loans are accounted for as available-for-sale securities and recorded at fair value. The Tranche A loan is classified as a short-term investment and included in current assets and the Tranche B loan is included in other assets on the Company’s Condensed Consolidated Balance Sheets. The Tranche B loan is subordinated to the Tranche A loan in the event of default, but otherwise has the same terms as the Tranche A loan. The CPTC Loans are collateralized by all of the assets of the Scripps Proton Therapy Center. Pursuant to the loan agreement, as amended in June 2014, the CPTC Loans mature in September 2017 and bear interest at the London Interbank Offer Rate (“LIBOR”) plus 7.00% per annum with a minimum interest rate of 9.00% per annum. Interest only payments on the CPTC Loans were due monthly in arrears until January 1, 2015, at which time monthly payments based on amortization of the principal balance over a 15-year period at the above mentioned interest rate became due and payable. To date no amortizing principal payments have been made. ORIX, J.P. Morgan and the Company (collectively the "Lenders") and CPTC continue to operate under the original terms of the loan while CPTC continues to ramp up patient volumes and works with other investors and the Lenders on an additional equity raise and/or modification to the loan terms. During the second quarter of fiscal year 2015, CPTC did not draw down on the CPTC Loans and has been operating using the cash generated from the center's operations. The Company has determined that CPTC is a variable interest entity and that the Company holds a significant variable interest of CPTC through its subsidiary’s participation in the loan facility and its agreements to supply and service the proton therapy equipment. The Company has concluded that it is not the primary beneficiary of CPTC. The Company has no voting rights, has no approval authority or veto rights for CPTC’s budget, and does not have the power to direct patient recruitment, clinical operations and management of the Scripps Proton Therapy Center, which the Company believes are the matters that most significantly affect CPTC’s economic performance. As of April 3, 2015, the Company had recorded $22.0 million in accounts receivable from CPTC, compared to $20.1 million as of September 26, 2014. As of September 26, 2014, the outstanding Tranche A loan balance to CPTC was $66.2 million and the outstanding Tranche B loan balance was $9.4 million. The Company’s exposure to loss as a result of its involvement with CPTC is limited to the carrying amounts of these assets on its Condensed Consolidated Balance Sheets.
