During 2007, the Company, through a noncontrolling interest in joint ventures, managed the formation of the Southern California Regional Gamma Knife Center at San Antonio Regional Hospital (“SARH”) in Upland, California. Corona Gamma Knife, LLC (“CGK”) is party to a 14-year agreement with SARH to renovate space in the hospital and install and operate a Leksell PERFEXION gamma knife. CGK leases the gamma knife from NeuroPartners LLC, which holds the gamma knife equipment. In addition to returns on its ownership interests, USNC expects to receive fees for management services relating to the facility.

USNC was a 20% guarantor on NeuroPartners LLC’s seven-year lease with respect to the gamma knife equipment and certain leasehold improvements at SARH. In February 2016, NeuroPartners LLC negotiated a new five-year lease to fund the reloading of cobalt and related construction services. The new lease of $1,663,000 included a balance of $668,000 from the prior lease obligations. This new lease was payable over 60 months. The first payment of $31,000 was paid on April 1, 2016, and the final payment was paid in March 2021, removing USNC’s guarantee obligation.

Construction of the SARH gamma knife center was completed in December 2008 and the first patient was treated in January 2009. The project has been funded principally by outside investors. While the Company, through its joint ventures, has led the effort in organizing the business and overseeing the development and operation of the SARH center, its investment to date in the SARH center has been minimal.

At December 31, 2021 and 2020, the Company’s recorded (loss) investment of NeuroPartners LLC and CGK was ($10,000) and $26,000, respectively. During the years ended December 31, 2021, and 2020, the Company’s equity in (loss) earnings of NeuroPartners LLC and CGK was ($36,000) and $124,000, respectively. At December 31, 2021 and 2020, amounts due from these related parties was $6,000 and $9,000, respectively.

During 2010, through the formation of a joint venture, in which it has a noncontrolling interest, the Company expanded its market strategy to include opportunities to develop cancer centers featuring radiation therapy. These centers utilize linear accelerators with IMRT and IGRT capabilities. In 2010, the Company formed FOP in partnership with local physicians and other investors. USNC owned a 24% interest in the venture. FOP’s first center was located in Miami, Florida and opened in the second quarter of 2011.

During 2011, FOP entered into a seven-year capital lease with Key Bank for $5,800,000. Under the terms of the capital lease, USN agreed to guarantee a maximum of $1,433,000, approximately 25% of the original lease obligation in the event of default. USN was a guarantor jointly with most of the other members of FOP. The guarantee was eliminated upon repayment of the outstanding lease balance in May 2018.

In December 2015, FOP entered into an agreement with 21st Century Oncology for the sale of FOP’s Varian Rapid Arc linear accelerator and other medical equipment at the FOP location. 21st Century Oncology paid FOP $1,000,000 as a down payment for the equipment and agreed to make monthly payments of $172,000 for the equipment and all monthly payments due under the equipment lease with Key Bank. As of this date, 21st Century Oncology had not satisfied all of the terms of the agreement. In May 2017, 21st Century Oncology filed for Chapter 11 bankruptcy protection and FOP was listed as an unsecured creditor. As a result, since June 2017, FOP has not received the agreed rental payments beyond the monthly payments for the equipment lease. As noted above, the equipment lease was repaid in May 2018 and title to the equipment was transferred to 21st Century Oncology. In December 2018, FOP was awarded 10,820 shares of 21st Century Oncology Holdings Inc. common stock as part of the bankruptcy proceedings. The title to these shares was transferred to USNC during 2020. The market value of these shares is unclear at this time as there is no readily available market for them, and accordingly, no value has been recorded for these shares as of December 31, 2021. During the year ended December 31, 2020, FOP received a payment of approximately $158,000 from 21st Century Oncology. FOP used these funds to repay $155,000 of previous advances from USNC.

Late in 2016, FOP took initial steps toward the development of a new radiation therapy center in Homestead, Florida. In December 2016, FOP entered into a ten-year lease agreement for office space located at 20405 Old Cutler Towne Center. FOP had to deliver an $88,000 letter of credit in conjunction with this office lease which collateral is being held in a restricted certificate of deposit. FOP began incurring architecture costs for planning/refitting the new space. During the first half of 2017, a financing agreement with BB&T Bank for the medical equipment and leasehold improvements was negotiated and then signed on August 31, 2017. In November 2017, the amounts for the equipment and leasehold improvements costs were finalized and paid under this financing agreement for a total loan of $4,106,000 to be paid over seven years. Under the terms of the financing agreement, USN agreed to guarantee the amount initially borrowed. USN was the guarantor with several other members of FOP. Effective November 15, 2019, FOP transferred this loan, along with the equipment acquired with the loan proceeds, to CBOP. The Company expects any potential liability from this guarantee to be reduced by the recoveries of the respective collateral. Late in the third quarter of 2017, it was determined that the business opportunity at this new location should be pursued by a different investor group, and FOP arranged to sell the opportunity to this group. CBOP was organized on September 1, 2017, to acquire the assets and rights in this new center from FOP.

In June 2017, FOP entered into an agreement with a third-party owner of a radiation therapy center located in Miami, Florida, whereby FOP took over the operation of the center effective September 22, 2017, for a ten-year initial term, and up to three additional terms of five years each. This agreement was accounted for as a capital lease and, accordingly, FOP recorded assets and capital lease liabilities totaling $14,321,000 at September 22, 2017. The lease required monthly payments in the first year of $160,000, increasing by 2% each year; currently the payment is $170,000. FOP abandoned its operations at this radiation center on June 28, 2019 due to continued losses at the site and lack of success in good faith efforts to renegotiate the agreement after several months of discussion. Due to the circumstances, FOP derecognized the associated assets and liabilities and calculated a contingent liability equal to the net liabilities derecognized. On November 24, 2021, the third-party owner filed a Voluntary Motion to Dismiss their lawsuit against FOP, and on December 11, 2021, it was accepted and recorded by the court. There can be no guarantee the third-party owner will not reinstitute any future claims against FOP.

During the quarter ended June 30, 2011, the Company, through the formation of a joint venture, in which it had a noncontrolling interest, participated in the formation of Boca Oncology Partners, LLC (“BOP”), for the purpose of owning and operating a cancer center in Boca Raton, Florida. In June 2011, BOPRE, an affiliated entity, purchased a 20% interest in Boca West IMP, owner of a medical office building in West Boca, Florida in which BOP operates. BOP occupies 6,000 square feet of the 32,000 square foot building. The Company invested $225,000 initially and had a 22.5% interest in BOP and BOPRE. In February 2014, the Company and other members sold their interests in BOP.

During the years ended December 31, 2018 and 2017, several investors relinquished part of their ownership interest in BOPRE, and those interests were distributed among the remaining investors in relationship to their percentages owned. During 2021 an additional member relinquished its ownership to USNC. As a result, the Company now holds a 22.5% ownership interest in BOPRE, which it accounts for under the equity method. The Company’s recorded investment in BOPRE is $151,000 and $134,000, at December 31, 2021 and 2020, respectively.

USNC was a 10% guarantor of 50% of the outstanding balance of Boca West IMP’s ten-year mortgage. This mortgage had an original balance of $3,000,000 and is secured by the medical office building in which BOP operates. In April 2020, the partners of Boca West IMP refinanced the mortgage in order to recover some of the cash that was invested before the building was completely occupied and removed USNC as a guarantor.

In April 2015, MOP, was formed in partnership with local physicians and other investors. MOP was established to acquire a 100% equity interest in UOMA. USNC was not a member of MOP at the time of formation as it was not able to participate due to the fact that USNC was not a physician. Nevertheless, USNC wished to eventually obtain an equity interest in MOP and loaned Dr. Jaime Lozano, the principal investor in MOP and a co-investor in FOP, $173,000. Dr. Lozano used these funds, along with an equal amount of his own funds (a total of $345,000), to purchase a 76.67% interest in MOP. Other investors paid a further $105,000 for the remaining equity in MOP. MOP used the $450,000 of financing to acquire a 100% equity interest in UOMA. An application was filed for a waiver to allow USNC to hold an equity interest notwithstanding the physician requirement and on December 22, 2016, USNC was cleared to become a part owner of MOP. Dr. Lozano agreed to exchange half of his membership interest to USNC in settlement of the note to USNC. USNC and Dr. Lozano also agreed to share equally in providing a 5% equity interest in MOP to an additional investor as a consulting fee for services rendered in the administration of MOP and UOMA. At December 22, 2016, USNC owned 35.83% of MOP with an initial carrying value of $161,000. The Company recorded its share of losses of $12,000 for the period from December 22, 2016 to December 31, 2016, against its investment which resulted in a reduction of its equity investment to $149,000.

Due to increasing costs, continued net losses since April 2015, and reliance on related party and other debt for operating cash flows, the fair value of UOMA is less than it’s carrying amount. The Company tested its investment for impairment at December 31, 2016 and determined that the investment was impaired, and an impairment loss was recorded against the entire equity balance in MOP, as well as loans from USN and USNC to MOP and UOMA. During the year ended December 31, 2020, USNC contributed $125,000 of capital to MOP all of which was written off. For the years ended December 31, 2021 and 2020, the Company’s equity in loss of MOP was $231,000 and $450,000, respectively, but was not recorded due to prior losses.

During the year ended December 31, 2020, the Company wrote off all amounts due and accrued interest thereon, from MOP and UOMA, resulting in a $686,000 loss. During the year ended December 31, 2021 the Company advanced an additional $461,000, all of which has been fully impaired. These allowances and write offs were recorded as losses from investments in unconsolidated entities.

Due to loans made to MOP and UOMA, MOP and UOMA are considered to be variable interest entities of the Company. However, as the Company is not deemed to be the primary beneficiary of MOP or UOMA, since it does not have the power to direct the operating activities that most significantly affect MOP’s or UOMA’s economic performance, the entities are not consolidated, but certain disclosures are provided herein.

CBOP was organized September 1, 2017, to acquire the rights of the new center from FOP. USNC originally had a 24% equity interest in CBOP. Beginning in October of 2017, CBOP began paying the remainder of the costs associated with opening the center. CBOP had no assets at the end of 2017. The medical center opened and treated its first patient in January of 2018.

Effective November 15, 2019, FOP transferred to, and CBOP assumed, a loan with BB&T bank, that it had entered into in order to finance the purchase of equipment and build out of the new center, as well as the associated property and equipment. In addition, CBOP and BB&T agreed to reduce the monthly loan repayments for the next nine months, and to extend the term of the loan from November 2024 to July 2025. In July 2020 CBOP and BB&T further agreed to reduce the monthly payments for the life of the loan and extended the loan to July of 2027.

In June 2020, CBOP made a $500,000 capital call to its members. UNSC converted previously-made advances totaling $121,000 into equity in CBOP to meet its capital requirement, and other members contributed $212,000 in cash. The remaining capital contributions are not expected to be met and, accordingly, the Company’s equity interest in CBOP increased to 28.58% in June 2020.

Amounts due from CBOP at December 31, 2021, total $2,174,000 of outstanding principal, less $1,251,000 of allowances, for a net receivable of $923,000 all of which is included in due from related parties on the accompanying Consolidated Balance Sheets. Amounts due from CBOP at December 31, 2020, total $2,154,000 of outstanding principal, less $1,251,000 of allowances, for a net receivable of $903,000 all of which is included in due from related parties on the accompanying Consolidated Balance Sheets. These balances accrue interest at 6% per annum. Interest earned by the Company from the amounts owed by CBOP totaled $125,000 for both the years ended December 31, 2021 and 2020. At December 31, 2021 and 2020, total accrued interest was $398,000 and $273,000, respectively, all of which has been fully reserved for. The Company records increases in the allowance, when applicable, as a component of loss from investments in unconsolidated entities and as a deduction in interest income for interest earned. For the years ended December 31, 2021 and 2020, the Company’s equity in loss of CBOP was $91,000 and $195,000, respectively, but was not recorded due to prior losses.

Due to loans made to CBOP, CBOP is considered to be a variable interest entity of the Company. However, as the Company is not deemed to be the primary beneficiary of CBOP, since it does not have the power to direct the operating activities that most significantly affect CBOP’s economic performance, the entity is not consolidated, but certain disclosures are provided herein.
