Variable Interest Entities

The Company has determined that MM Proton I, LLC and RPTC are variable interest entities and that the Company holds a significant variable interest of each of the entities through its participation in the loan facilities and its agreements to supply and service the proton therapy equipment. The Company has concluded that it is not the primary beneficiary of any of these entities. The Company has no voting rights, has no approval authority or veto rights for these centers' budget, and does not have the power to direct patient recruitment, clinical operations and management of these Centers, which the Company believes are the matters that most significantly affect their economic performance. The Company’s exposure to loss as a result of its involvement with MM Proton I, LLC and RPTC is limited to the carrying amounts of the above-mentioned assets on its Condensed Consolidated Balance Sheets.

California Proton Therapy Center ("CPTC") Loans and Investment

Between September 2011 and November 2015, the Company, ORIX and J.P. Morgan (“the Lenders”) funded loans (“Original CPTC Loans”) to the Scripps Proton Therapy Center in San Diego, California. ORIX is the loan agent.

In March 2017, California Proton Treatment Center, LLC ("Original CPTC") filed for bankruptcy and concurrently entered into a Debtor-in-Possession facility (the "DIP Facility") with the Lenders where the Company's pro-rata share of the DIP Facility was $7.3 million. In September 2017, the Lenders and Scripps signed a Transition Agreement to transition the operations of the center from Scripps to Proton Doctors Professional Corporation (“Practice”). As a result of these events, the Company recorded an impairment charge of $51.4 million to its Original CPTC Loans in fiscal year 2017.

Pursuant to an order of the Bankruptcy Court, the California Proton Treatment Center ("Original CPTC") conducted an auction of the Scripps Proton Therapy Center. On December 6, 2017 (“Closing Date”), the Bankruptcy Court approved the sale of Scripps Proton Therapy Center to California Proton Therapy Center, LLC (“CPTC”), an entity owned by the Lenders. The Lenders purchased all assets and assumed $112.0 million of Original CPTC’s outstanding liabilities. On December 13, 2017, the Bankruptcy Court dismissed the bankruptcy filing of Original CPTC.

On the Closing Date, the Lenders entered into a Credit Agreement with Original CPTC of which the terms of the Original CPTC Loans, DIP Facility and accrued interest (collectively “Former Loans”) have been modified. In addition to the partially satisfied Original CPTC Loans reinstated by the Bankruptcy Court, the Company received a 47.08% equity ownership in CPTC. Original CPTC has assigned all its Former Loans to CPTC at an amount of $112.0 million, the partially satisfied loan balance. Per the terms of the Credit Agreement, the Company's portion of the $112.0 million is $53.5 million; the remainder is allocated between ORIX and J.P. Morgan. The $53.5 million is composed of four tranches: Tranche A of $2.0 million, Tranche B of $7.2 million, Tranche C of $15.6 million, and Tranche D of $28.7 million (collectively the "Term Loan"). The maturity date of the Term Loan is three years from the Closing Date. The Term Loan is secured by the assets of CPTC.

In addition, the Lenders have committed to lend up to $15.0 million in a Revolving Loan with a maturity date of one year from the Closing Date. In the first quarter of fiscal 2019, as provided in the initial agreement, the Lenders granted a one year extension to the term of the Revolving Loan. The Company's share of the funding commitment from the Revolving Loan is $7.2 million, and as of December 28, 2018, the Company has funded $4.2 million.

All of the tranches accrue paid-in-kind interest at 7.5% per annum, except the Tranche B and the Revolving Loan, which accrue paid-in-kind interest at 10% per annum. The seniority of these loans is as follows: Revolving Loan, Tranche A, Tranche B, Tranche C and Tranche D. If CPTC is in default, the interest rate of the Tranche A, C and D will increase to 9.5% and the interest rate on the Tranche B and the Revolving Loan will increase to 12.0%.

Considering Original CPTC’s financial difficulties, the modification of the original terms of the Former Loans, and the Lenders agreement to grant a concession on the Original CPTC Loans, the Company classified the transaction above as a troubled debt restructuring (“TDR”). The Company does not have any unamortized fees from the Former Loans and any prepayment penalties.

The Company, using a discounted cash flow approach, determined that the fair value of CPTC's equity as of Closing Date was $20.1 million. The Company's 47.08% ownership percentage amounts to a $9.5 million equity interest in CPTC. Since the common stock received was in addition to a loan receivable partially satisfied through the bankruptcy proceedings, in accordance with the TDR accounting guidance, the Company recorded the equity interest at fair value and as an offset to the reinstated loan balance. The equity investment in CPTC is accounted for under the equity method of accounting, and the Company accounts for its equity method share of the income or loss of CPTC on a quarter lag basis. The Company recorded a loss from its equity investment in CPTC of $2.2 million in the three months ended December 28, 2018 in selling, general and administrative expenses on the Condensed Consolidated Statements of Earnings (Loss).

As of December 28, 2018 and September 28, 2018, the Company had recorded $1.5 million and $1.8 million, respectively, in accounts receivable, net, from CPTC.

Further, the Company has determined that CPTC is a variable interest entity because of the Company's participation in the loan facilities, equity ownership and its operations and maintenance agreement. The Company has one board seat out of five, has no special approval authority or veto rights for CPTC’s budget, and does not have the power to direct patient recruitment, clinical operations and management of CPTC, which the Company believes are the matters that most significantly affect their economic performance. Therefore, the Company does not have majority voting rights and no power to direct activities at CPTC, and as a result it is not the primary beneficiary of CPTC.
