Item 1.

Business.

U.S. NeuroSurgical Holdings, Inc. owns and operates, through its wholly-owned subsidiaries, stereotactic radiosurgery centers, utilizing gamma knife technology, and holds other interests in radiological treatment facilities. As used herein, unless the context indicates otherwise, the term “Company”, “Registrant” and “Holdings” means U.S. NeuroSurgical Holdings, Inc. and its wholly-owned subsidiary, U.S. NeuroSurgical, Inc. (“USN”), and the wholly-owned subsidiaries of USN, U.S. NeuroSurgical Physics, Inc. and USN Corona, Inc.

USN, a Delaware corporation, was formed in July 1993. Until September 1999, USN was a wholly owned subsidiary of GHS, Inc. (“GHS”). Effective September 17, 1999, GHS distributed its shares of USN to the stockholders of GHS.

On September 3, 2015, pursuant to the Agreement and Plan of Reorganization (the “ Merger Agreement ”), dated as of September 3, 2015, by and among USN, Holdings and U.S. NeuroSurgical Merger Sub, Inc. (“ Merger Sub ”), the Company adopted a new holding company organizational structure whereby USN is now a wholly owned subsidiary of Holdings. This structure did not result in any changes to the assets or operations of the Company, but management believes that it will create a more flexible framework for possible future transactions and organizational and operational adjustments.

The holding company organizational structure was effected by a merger (the “ Merger ”) conducted pursuant to Section 251(g) of the Delaware General Corporation Law (the “ DGCL ”), which provides for the formation of a holding company structure without a vote of the stockholders of the constituent corporations. Because the holding company organizational structure occurred at the parent company level, the remainder of the Company’s subsidiaries, operations and customers were not affected by this transaction.

In order to effect the Merger, USN formed Holdings as its wholly owned subsidiary and Holdings formed Merger Sub as its wholly owned subsidiary. Under the terms of the Merger Agreement, Merger Sub merged with and into USN, with USN surviving the merger and becoming a direct, wholly owned subsidiary of Holdings. Immediately prior to the Merger, Holdings had no assets, liabilities or operations.

Pursuant to the Merger Agreement, all of the outstanding capital stock of USN was converted, on a share for share basis, into capital stock of Holdings. As a result, each former stockholder of USN became the owner of an identical number of shares of capital stock of Holdings, evidencing the same proportional interests in Holdings and having the same designations, rights, powers and preferences, qualifications, limitations and restrictions, as those that the stockholder held in USN.

Following the Merger, Holdings’ common stock continued to trade on the over-the-counter market and continued to be quoted on the OTC Pink marketplace under the same symbol, “USNU.” The conversion of shares of capital stock under the Merger Agreement occurred without an exchange of physical certificates. Accordingly, physical certificates formerly representing shares of outstanding capital stock of USN are deemed to represent the same number of shares of capital stock of Holdings.

Table of Contents

Pursuant to Section 251(g) of the DGCL, the provisions of the certificate of incorporation and bylaws of Holdings are substantially identical to those of USN prior to the date on which the Merger Agreement took effect. The authorized capital stock of Holdings, the designations, rights, powers and preferences of such capital stock, and the qualifications, limitations and restrictions thereof are also substantially identical to those of the capital stock of USN immediately prior to the date of the Merger. Further, the directors and executive officers of Holdings are the same individuals who were directors and executive officers, respectively, of USN immediately prior to the date of the Merger.

The Company’s executive offices are located at 2400 Research Boulevard, Suite 325, Rockville, Maryland 20850, and its telephone number is (301) 208-8998.

Disclosure Regarding Forward Looking Statements

Statements contained in this Annual Report on Form 10-K that are not historical facts are forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Investors are cautioned that forward-looking statements are inherently uncertain. Actual performance and results may differ materially from that projected or suggested herein due to certain risks and uncertainties including, without limitation, the timing and ultimate collectability of accounts receivable for gamma knife procedures from different payor groups such as Medicare and private payors; competition; technological obsolescence; government regulation and malpractice liability. Additional information concerning certain risks and uncertainties that could cause actual results to differ materially from that projected or suggested are included in Item 1A, Risk Factors, and may also be identified from time to time in the Company’s filings with the Securities and Exchange Commission (the “SEC”) and the Company’s public announcements, copies of which are available from the SEC or from the Company upon request.

General

The Company and its predecessors have owned and operated stereotactic radiosurgery centers, utilizing gamma knife technology since 1993. The Company currently holds an interest in and operates one gamma knife center on the premises of New York University Medical Center (“NYU”) in New York, New York. In January 2009, the Company, through its noncontrolling interest in Corona Gamma Knife, LLC, participated in the opening of a new center, the Southern California Regional Gamma Knife Center, at the San Antonio Regional Hospital (“SARH”) in Upland, California.

Management continues to explore opportunities to organize and participate in additional gamma knife centers. The Company’s business strategy is to provide cost-effective approaches that allow hospitals, physicians, and patients access to gamma knife treatment capability, a high capital cost item. The Company provides the gamma knife to medical facilities on a “cost per treatment” basis. The Company’s business model is to own, or hold an interest in, the gamma knife units, and charge the medical facility, where the unit is housed and maintained, based on utilization. During 2018, the Company’s arrangement with its only customer met the criteria for classification as a sales type lease, and the Company was deemed to have sold its sole gamma knife.

During the fourth quarter of 2007, the Company formed a new wholly owned subsidiary, USN Corona, Inc. (“USNC”), to carry investments in Corona Gamma Knife, LLC and NeuroPartners, LLC. Those business units were formed to develop and manage the gamma knife center at SARH.

Table of Contents

The Company’s principal target market is medical centers in major health care catchment areas that have physicians experienced with and dedicated to the use of the gamma knife. As it has with the NYU and SARH gamma knife centers, if circumstances support the opening of additional centers, the Company would seek, through the formation of a joint venture, cooperative ventures with these facilities.

The Company estimates that, as of December 31, 2020, there were approximately 120 gamma knife treatment centers in the U.S.

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 (Intensity Modulated Radiation Therapy) and IGRT (Image Guided Radiation Therapy) capabilities. In 2010, the Company formed Florida Oncology Partners, LLC (“FOP”) in partnership with local physicians and other investors. USNC owns a 24% interest in the venture. FOP’s first center was located in Miami, Florida and opened in the second quarter of 2011. The Company entered into an arrangement to sell this center to 21st Century Oncology in December of 2015. The recognition of the sale had not occurred as of December 31, 2020.

In 2015, Medical Oncology Partners LLC (“MOP”), was formed in partnership with local physicians and other investors. MOP was established to acquire a 100% equity interest in United Oncology Medical Associates of Florida, LLC (“UOMA”) USNC was not initially a member of MOP as it was legally not able to participate due to the fact that USNC was not a physician. Paperwork was filed for a waiver and on December 22, 2016, USNC was cleared to become a part owner of MOP. USNC currently owns 35.83% of MOP.

Late in 2016, FOP took initial steps toward the development of a new radiation therapy center in Homestead, Florida. However, 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. CB Oncology Partners, LLC, (“CBOP”) was organized September 1, 2017 to acquire the rights of the 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. The intent was for FOP to operate the center for at least 10 years, but in June 2019 FOP ceased operations at the center. Due to abandoning the operations of the Miami center as well as continued working capital deficits, FOP’s ability to continue as a going concern will require FOP to restructure debt, raise new capital, and successfully settle the agreement at the center in Miami, Florida. Since these plans are preliminary and have not been approved at this date, there is substantial doubt about FOP’s ability to continue as a going concern within the next twelve months from the date these consolidated financial statements are available to be issued.

The Company, through its noncontrolling interest in joint ventures, is currently exploring other opportunities for the establishment of cancer centers using IMRT and/or IGRT in Florida and other parts of the U.S.

Gamma Knife Technology

The gamma knife is a unique stereotactic radiosurgical device used to treat brain tumors and other malformations of the brain without invasive surgery. The gamma knife delivers a single, high dose of ionizing radiation emanating from 201 cobalt-60 sources positioned about a hemispherical, precision machined cavity. The lesion is first targeted with precision accuracy using advanced imaging and three-dimensional treatment planning techniques such as CT Scans, MR Scans, conventional X-rays, or angiography. Each individual beam is focused on a common target producing an intense concentration of radiation at the target site, destroying the lesion while spreading the entry radiation dose uniformly and harmlessly over the patient’s skull. The mechanical precision at the target site is +/- 0.1mm (1/10 of 1 millimeter). Because of the steep fall-off in the radiation intensity surrounding the target, the lesion can be destroyed, while sparing the surrounding tissue.

The procedure, performed in a single treatment, sharply reduces hospital stay times and eliminates post-surgical bleeding and infection. When compared with conventional neurosurgery, gamma knife treatment is less expensive. However, not all patients are candidates for radiosurgery since the decision to use the gamma knife depends on the type, size, and location of the lesion.

Linear Accelerators

A linear particle accelerator (LINAC) is a type of particle accelerator that greatly increases the velocity of charged subatomic particles or ions by subjecting the charged particles to a series of oscillating electric potentials along a linear beamline. LINACs accelerate electrons using a tuned-cavity waveguide, in which the RF (radio frequency) power creates a standing wave. Some LINACs have short, vertically mounted waveguides, while higher energy machines tend to have a horizontal, longer waveguide and a bending magnet to turn the beam vertically towards the patient. Medical LINACs use monoenergetic electron beams between 4 and 25 MeV, giving an X-ray output with a spectrum of energies up to and including the electron energy when the electrons are directed at a high-density (such as tungsten) target. The electrons or X-rays can be used to treat both benign and malignant disease.

The intensity of the radiation in IMRT can be changed during treatment to spare more adjoining normal tissue than is spared during conventional radiation therapy. Because of this an increased dose of radiation can be delivered to the tumor using IMRT. IMRT is a type of conformal radiation, which shapes radiation beams to closely approximate the shape of the tumor.

IGRT is used to help better deliver radiation therapy to cancerous tumors. This is very useful since tumors can move between treatments due to differences in organ filling or movements while breathing. IGRT involves conformal radiation treatment guided by specialized imaging tests, such as CT scans, ultrasound or X-rays. These tests are done in the treatment room just before the patient is to receive his or her daily radiation therapy treatment.

New York Gamma Knife Center

The Company’s New York gamma knife treatment center was opened in July 1997 on the campus of NYU. The Company installed a new Leksell gamma knife, the PERFEXION model, at the NYU Medical Center in March 2009 in replacement of the older gamma knife equipment. In connection with this upgrade, the Company modified its arrangement with NYU to extend the term for 12 years from March 2009.

Table of Contents

In October 2012, the Company’s facility at NYU was totally destroyed as a result of flooding from Hurricane Sandy. The gamma knife had to be removed to prevent any cobalt leakage that might occur due to rusting of the equipment. The removal cost was $525,000. The Company paid a lease settlement of the outstanding principal balance only and received from insurance coverage $930,000 above the lease principal payments and removal costs.

The Company finalized arrangements with NYU regarding the restoration of the gamma knife center and entered into an amendment to the original Gamma Knife Neuroradiosurgery Equipment Agreement (“NYU Agreement”). The NYU facility was rebuilt and reopened in the Tisch Hospital of NYU Langone Medical Center. The first patient was treated on April 29, 2014. The Company expects to generate revenue from the restored gamma knife center under the NYU contract until March 2021, at which time the NYU contract ended and title to the gamma knife transferred to NYU.

The Company is responsible for the maintenance and insurance for the gamma knife equipment at the NYU facility and earns income for use of the gamma knife based on a fee per procedure performed with the equipment. NYU provides the medical and technical staff to operate the facility.

The Company entered into a six-year lease in the amount of $4.7 million for the purchase of the replacement equipment and associated leasehold improvements. The lease payments commenced in September 2014 and ended in May 2020. The Company entered into a second two-year lease in the amount of $250,000 for the cost of the construction required at the relocated site. The lease ended in 2016.

NYU pays the Company a scheduled fee based on the number of patient procedures performed. There were 462 patients treated during the year ended December 31, 2020, whereas in the prior year there were 559 patients treated at the facility. Total revenue in 2020 from NYU was $3,173,000 as opposed to total revenue of $3,070,000 in 2019.

In 2016, the Company entered into an agreement with Elekta for the installation of new ICON imaging technology for the NYU Gamma Knife equipment with a total cost, including sales taxes, of $816,000. This ICON technology was installed during the month of July 2016 and the gamma knife center reopened on August 5, 2016. The Company entered into a four-year lease for $879,000 to finance the acquisition of the ICON technology and associated installation costs. A monthly maintenance agreement commenced a year after the installation date for $6,000 per month. The two parties also agreed for USN to receive a fixed monthly payment of $30,000 for the remaining term of the agreement through March 2021.

In September 2017, the Company and NYU entered into an additional amendment to the NYU Agreement, whereby NYU committed to purchase all of the gamma knife equipment at the NYU Medical Center for a purchase price of $2,400,000, with 41 monthly installments of $50,000 from October 2017 through February 2021, and a final payment of $350,000 on March 31, 2021. Previously, the NYU agreement ended on March 17, 2021 and NYU had an option to purchase the gamma knife equipment at the estimated future value of the equipment at that time. In June 2017, the Company obtained an independent estimate of $2,570,000 for the fair value of the equipment in March 2021. The Company believes that the accelerated payments amounting to $2,400,000 represent fair consideration considering all aspects of the transaction.

Table of Contents

With the September 2017 amendment, the Company became obligated to reload the cobalt for the gamma knife at its own expense and bear the cost of site work involved in reloading the cobalt, up to a maximum of $1,088,000. In July 2018, the Company entered into an agreement with Elekta for the cobalt reload on the NYU gamma knife equipment with a cost, including sales taxes, of $925,000. This cobalt reload occurred in July 2018, and the gamma knife center reopened on August 6, 2018. The Company obtained lease financing of $833,000 to partially finance the reload of the cobalt and paid the remaining balance directly to Elekta. In addition, the Company incurred costs of $578,000 to install the new cobalt to be paid directly to the contractor. All cobalt related costs were finalized by October 1, 2018 and totaled $1,503,000. As a result of the Company satisfying its obligation to reload the cobalt, the agreement with NYU met the criteria to be classified as a sales type lease. In addition, the Company is now no longer obligated to restore the NYU facility to its original condition. Accordingly, all related assets and the asset retirement obligation were derecognized effective October 1, 2018.

The Southern California Regional Gamma Knife Center

During 2007, the Company, through a noncontrolling interest in joint ventures, managed the formation of the Southern California Regional Gamma Knife Center at 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 is a 20% owner of NeuroPartners LLC and owns 39% of CGK.

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 on March 1, 2021. The Company continues to be a 20% guarantor on the new lease and expects any potential obligations from this guarantee would be reduced by the recovery of the related collateral, and thus expects any exposure from this guarantee to be remote.

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, 2020 and 2019, the Company’s recorded investment in NeuroPartners LLC and CGK was $26,000 and $0, respectively. During the years ended December 31, 2020 and 2019, the Company’s equity in earnings in NeuroPartners LLC and CGK was $124,000 and $92,000, respectively. At December 31, 2020 and 2019, amounts due from related parties was $9,000 and $31,000, respectively, including $20,000 of distributions receivable at December 31, 2019, which distributions were received in 2020.

Future Gamma Knife Centers

The Company is currently exploring other opportunities for gamma knife centers and centers that provide related healthcare services located near hospitals throughout the United States. Discussions regarding such centers is preliminary and there can be no assurance that any such discussions will result in the opening of new centers.

Florida Oncology Partners

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 21 ^st Century Oncology for the sale of FOP’s Varian Rapid Arc linear accelerator and other medical equipment at the FOP location. 21 ^st 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, 21 ^st Century Oncology has not satisfied all of the terms of the agreement. In May 2017, 21 ^st 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 21 ^st Century Oncology. In December 2018, FOP was awarded 10,820 shares of 21 ^st 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 at December 31, 2020 by USNC, or December 31, 2019 by FOP. During the year ended December 31, 2020, FOP received a payment of approximately $158,000 from 21 ^st Century Oncology. FOP used these funds to repay $155,000 of previous advances from USNC. FOP will continue to monitor the impact of 21 ^st Century Oncology’s bankruptcy and pursue amounts that it is owed. However, there can be no assurance that FOP will be successful in these efforts.

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 is the guarantor with several other members of FOP. The outstanding balance on the financing facility was $3,066,000 at December 31, 2020 and $3,273,000 at December 31, 2019. 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. FOP could be considered in default of the agreement and the third-party owner could pursue action against FOP. Due to the circumstances, FOP derecognized the associated assets and liabilities and calculated a contingent liability equal to the net liabilities derecognized. FOP has not, however, been released from its contractual obligation to the third-party owner. At December 31, 2020, FOP was obligated to make a further $17.6 million of lease payments for the period from July 2019 to September 2027, with no payments made since June 2019. Due to abandoning the operations of the Miami center as well as continued working capital deficits, FOP’s ability to continue as a going concern will require FOP to restructure debt, raise new capital, and successfully settle the agreement at the center in Miami, Florida. Since these plans are preliminary and have not been approved at this date, there is substantial doubt about FOP’s ability to continue as a going concern within the next twelve months from the date these Consolidated Financial Statements are available to be issued.

The Company’s recorded investment in FOP at December 31, 2020 and 2019 has been reduced to zero due to losses incurred in prior years. No equity in earnings has been recorded by the Company for the years ended December 31, 2020 and 2019, due to FOP’s deficit at December 31, 2020 and 2019.

Amounts due from FOP at December 31, 2019 total $649,000 of outstanding principal less $588,000 of allowances, for a net receivable balance of $61,000, included in due from related parties on the accompanying Consolidated Balance Sheet. These balances accrued interest at 6% per annum. During the year ended December 31, 2020, the Company wrote off all remaining amounts due from FOP and accrued interest thereon, resulting in a $78,000 loss. During the year ended December 31, 2020, FOP repaid $155,000 of the amounts due to the Company. At December 31, 2019, total accrued interest was $68,000. The Company has recorded a full allowance against the accrued interest at December 31, 2019. The Company recorded amounts written off and increases in the allowances as a component of loss from investments in unconsolidated entities and as a deduction in interest income for interest earned.

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

Boca Oncology Partners

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, Boca Oncology Partners RE, LLC (“BOPRE”), an affiliated entity, purchased a 20% interest in Boca West IMP, LLC, (“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.

In June 2012, BOPRE purchased an additional 3.75% of Boca West IMP from another investor bringing its total interest to 23.75%. BOPRE accounts for this investment under the cost method since it does not exercise significant influence over Boca West, IMP.

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. As a result, the Company now holds a 21.22% ownership interest in BOPRE, which it accounts for under the equity method. The Company’s recorded investment in BOPRE is $134,000 and $179,000 at December 31, 2020 and 2019, respectively, which is net of $58,000 of distributions received from BOPRE during the year ended December 31, 2020.

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.

Medical Oncology Partners

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.

Table of Contents

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 its 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 year ended December 31, 2020 and 2019, the Company’s equity in loss of MOP was $450,000 and $156,000, respectively, but was not recorded due to prior losses.

At December 31, 2019 amounts due from MOP and UOMA total $1,126,000 of outstanding principal less $796,000 of allowances, for a net receivable of $330,000, all of which is included in due from related parties on the accompanying Consolidated Balance Sheet. During the year ended December 31, 2020, the Company wrote off all remaining amounts due from MOP and UOMA and accrued interest thereon, resulting in a $686,000 loss. Increases in these allowances and amounts written off have been 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.

CB Oncology Partners

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.

Table of Contents

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, 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 Sheet. At December 31, 2019, CBOP owed the Company $2,207,000, of which $1,207,000 had been reserved for a net receivable of $1,000,000, all of which is included in due from related parties on the accompanying Consolidated Balance Sheet. These balances accrue interest at 6% per annum. Interest earned by the Company from the amounts owed by CBOP totaled $125,000 and $103,000 for the years ended December 31, 2020 and 2019 respectively. At December 31, 2020 and 2019, total accrued interest was $273,000 and $148,000, respectively, all of which has been fully reserved for. The Company recorded increases in the allowance as a component of loss from investments in unconsolidated entities and as a deduction in interest income for interest earned.

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.

Strategy for Participation in Cancer Treatment

As a result of the Company’s experiences over the past few years, the Company, through unconsolidated joint ventures, has expanded its focus to the broader based cancer treatment market. In order to reduce the risk and broaden its opportunities for profitable growth, the Company, through unconsolidated joint ventures, where possible, has been pursuing partnerships with local investors/providers to develop and operate oncology centers that utilize LINACs to treat cancers in the whole body. The Company also continues to evaluate opportunities to develop additional gamma knife facilities. FOP, BOP and the Southern California Regional Gamma Knife Center typify this strategy.

Employees

USN has three full-time employees and relies on consultants for certain services as required from time-to-time. All of its full-time employees are engaged in sales, marketing and administration.

Item 1A.

Risk Factors.

Regulatory Environment

The levels of revenues and profitability of companies involved in the health services industry, such as the Company, may be affected by the continuing efforts of governmental and third-party payors to contain or reduce the costs of health care through various means. Although the Company does not believe that its business activities will be materially affected in the foreseeable future, it is not possible to predict the long term effect of recent and future changes in the regulatory environment, or the responses of federal, state or private payors for healthcare goods and services in response to healthcare proposals or legislation.

Table of Contents

In March 2010, significant reforms to the healthcare system were adopted in the form of the Patient Protection and Affordable Care Act (the “PPACA”). The PPACA includes provisions that, among other things, reduce and/or limit Medicare reimbursement to certain providers, require all individuals to have health insurance (with limited exceptions) and impose new and/or increased taxes. The Company cannot predict the effects these changes may have on its business, and no assurance can be given that any such changes will not have a material adverse effect on the Company.

In addition, the provision of medical services in the United States is dependent on the availability of reimbursement to consumers from third party payors, such as government and private insurance companies. Although patients are ultimately responsible for services rendered, the Company expects that the majority of its revenues will be derived from reimbursements by third party payors. Medicare has authorized reimbursement for gamma knife and other forms of cancer treatment. Over the last several years, such third-party payors are increasingly challenging the cost effectiveness of medical products and services and taking other cost containment measures. Therefore, although treatment costs using the gamma knife compare favorably to traditional invasive brain surgery, it is unclear how this trend among third party payors and future regulatory reforms affecting governmental reimbursement will affect procedures in the higher end of the cost scale.

In the future, the Company may establish additional gamma knife or other types of cancer treatment centers. Completion of future centers would require approvals and arrangements with hospitals, health care organizations, or other third parties, including certain regulatory authorities. The Food and Drug Administration has issued the requisite pre-market approval for the gamma knife utilized by the Company. In addition, many states require hospitals to obtain a Certificate of Need (“CON”) before they can acquire a significant piece of medical equipment. Should the Company enter into future ventures such “need” will be demonstrable, but it can have no assurance that CONs will be granted. In addition, the Nuclear Regulatory Commission (the “NRC”) must issue a permit to the Company to permit loading the cobalt at each gamma knife site. While the Company believes that it can obtain an NRC permit for each gamma knife unit, there is no assurance that it will.

Liability Insurance

Although the Company does not directly provide medical services, it has obtained professional medical liability insurance, and has general liability insurance as well. The Company’s professional medical liability and general liability policies have limits of $3 million each. The Company believes that its insurance is adequate for providing treatment facilities and non-medical services, although there can be no assurance that the coverage limits of such insurance will be adequate or that coverage will not be reduced or become unavailable in the future.

Table of Contents

Competition

The health care industry, in general, is highly competitive and the Company expects to have substantial competition from other independent organizations, as well as from hospitals in establishing future gamma knife or other types of cancer treatment centers. There are other companies that provide gamma knife or other types of cancer treatment on a “cost per treatment basis”. In addition, larger hospitals may be expected to maintain a gamma knife as well as competing technologies as part of their regular inpatient services, which could have the effect of reducing the number of gamma knife procedures performed at such facility. Principal competitive factors include quality and timeliness of test results, ability to develop and maintain relationships with referring physicians, facility location, convenience of scheduling and availability of patient appointment times. The Company believes that cost containment measures will encourage hospitals to seek companies that are providing the technology, instead of incurring the capital cost of establishing their own treatment centers.

Gamma Knife Financing

The gamma knife is an expensive piece of equipment, presently costing from $3.0 to $4.5 million, depending on features. Therefore, the Company’s development of new gamma knife centers is dependent on its ability to secure favorable financing. In addition, after a number of years of use, the radioactive cobalt contained in the gamma knife requires replacement. This is also an expensive process. For example, the cobalt for the Company’s current gamma knife in the NYU facility was reloaded in July 2018 and the costs were approximately $1,500,000.

Gamma Knife Supply and Servicing

To date, the Company has purchased all of its gamma knife equipment from Elekta Instruments, Inc., a subsidiary of AB Elekta of Stockholm, Sweden. Elekta is responsible for the installation and testing of the equipment and the training of the hospital staff in the operation of the equipment. The Company arranges for maintenance services for its gamma knife units, including the necessary services related to cobalt replacement, through Elekta. Any interruption in the supply of equipment or services from Elekta would adversely affect the Company’s ability to maintain its gamma knife treatment centers.

Also, should restrictions be imposed on the operations of Elekta, such as restrictions relating to the handling and disposal of radioactive materials, necessary support services could become more costly and more difficult to obtain.

New Technology/Possible Obsolescence

Gamma knife technology may be subject to technological change. Consequently, the Company will have to rely on the leading gamma knife’s manufacturer, Elekta, to introduce improvements or upgrades in order to keep pace with technological change. Any such improvements or upgrades which the Company may be required to introduce will require additional financing. In addition, newly developed techniques and devices for performing brain surgery may render the gamma knife less competitive or obsolete.

Table of Contents

Dependence on Hospital, Healthcare Organizations and Others

In establishing new gamma knife centers, the Company must reach an arrangement with a hospital or other medical center for the installation and operation of a gamma knife facility and then to purchase the gamma knife equipment and construct and operate the facility. Before entering into such an agreement, the Company must make an assessment of the economic feasibility of operating the gamma knife at that location. The Company retains no control or influence over the medical staff or decisions regarding the treatment of patients. In that regard, the Company’s economic success is highly dependent on its initial determinations of the viability of the gamma knife’s location. Should the medical center or the physicians at that medical center ultimately use the gamma knife facility for significantly fewer patients than initially projected, the Company could be required to operate the gamma knife center at a loss for an extended period of time.

With respect to other cancer centers in which the Company has an interest, the Company participates with other physician groups and other investors in planning and constructing the facility and purchasing the necessary equipment, such as an IMRT or IGRT. The Company plays a lead role in the initial planning and establishment of those centers but does not control the day-to-day operations thereafter. The long-term success of those centers depends to a significant degree on the operating decisions made by the physicians and administrators at those centers.

Reliance on Business of the New York University Gamma Knife Center; Recent Destruction of Equipment and Discontinuation of Business at NYU

While it is the Company’s objective to expand activities to additional cancer centers that rely on a broad range of diagnostic and radiation treatments, the Company has relied on the NYU gamma knife for substantially all of its revenue. In recent periods, services provided at NYU have represented over 90% of the Company’s revenues. Unless and until the Company is successful in building its activities at other centers and at new locations, disruptions at NYU could have a materially adverse effect on the Company.

In October 2012, the Company’s facility at NYU was totally destroyed as a result of flooding from Hurricane Sandy. The gamma knife had to be removed to prevent cobalt leakage that might occur due to rusting of the equipment.

In addition, the cost of the removal of the damaged equipment was $525,000. The Company paid a lease settlement of the outstanding principal of the loan balance only and received from insurance coverage $930,000 above the lease principal payments and removal costs.

The Company has finalized arrangements with NYU regarding the restored gamma knife center and the Company’s long-term contract with NYU. The location of the restored facility, with the new Leksell PERFEXION gamma knife, is in the Tisch Hospital of NYU Langone Medical Center. The center reopened and the first patient was treated on April 29, 2014. Substantially all of the Company’s revenue for 2020 and 2019 resulted from patients treated at this facility. The Company’s lease with NYU ends in March 2021, and it has agreed to sell its gamma knife to NYU at the end of the lease term. Effective October 1, 2018 the Company’s arrangement with NYU met the criteria to be classified as a sales-type lease, resulting in the derecognition of the gamma knife and related assets and obligations.

The COVID-19 Outbreak May Continue to Adversely Affect Our Business Operations and Financial Condition.

The novel coronavirus COVID-19 pandemic has had a materially adverse effect on operations in New York and Florida and could continue to impact our business in all locations. Most states and municipalities in the U.S., including New York, California, and Florida, continue to take action to reduce the spread of the disease, including limiting non-essential gatherings of people, ceasing all non-essential travel, ordering certain businesses and government agencies to cease non-essential operations at physical locations and issuing “shelter-in-place” orders, which direct individuals to shelter at their places of residence (subject to limited exceptions). Across the healthcare industry, resources are being prioritized for the treatment and management of the outbreak. Consequently, there are delays in delivering Gamma Knife and other radiation therapy treatments. In addition, the COVID-19 pandemic poses the risk that the Company and its employees, contractors, customers, government and third-party payors and others may be prevented from conducting business activities for an indefinite period of time, including due to spread of the disease within these groups or due to shutdowns that have been and may continue to be requested or mandated by governmental authorities.

While the healthcare treatments that are provided by the Company are generally critical to the well-being of the patients it serves, a sustained COVID-19 pandemic, and continued measures by government and the healthcare industry to contain the pandemic, could negatively impact results for the following reasons: (i) operations at medical facilities, including those operated by the Company, could be subject to reduced operation or prolonged closure; (ii) medical facilities may defer Gamma Knife and other cancer therapy treatments for non-urgent patient cases in order to allocate resources to the care of patients with COVID-19; (iii) patients may defer or cancel treatments due to real or perceived concerns about the potential spread of COVID-19 in a medical facility setting; (iv) the outbreak could materially impact operations for a sustained period of time due to the current travel bans and restrictions, quarantines, shelter-in-place orders and shutdowns; and/or (v) members of the Company’s workforce may become ill or have family members who are ill and are absent as a result, or they may elect not to come to work due to the illness affecting others in our office or facilities.

The occurrence of any of the foregoing events could have a material adverse effect on our business, financial condition and results of operations. The COVID-19 outbreak and mitigation measures have had and may continue to have an adverse impact on global economic conditions which could have an adverse effect on our business and financial condition. The extent to which the COVID-19 outbreak impacts our results will depend on future developments that are highly uncertain and cannot be predicted, including new information that may emerge concerning the severity of the virus and the actions to contain its impact. Although the Company’s contract with its only customer ended in March 2021, the Company is actively seeking new business ventures and believes that its cash reserves, which are in excess of $2 million at December 31, 2020, will allow the Company the opportunity do so. Such plans include possible new operations or extensions of its activities in Florida and California, where it has established working relationships with physician groups, hospitals and other organizations. In addition to these activities, the Company has been exploring possible combinations with other existing businesses that would create a larger operating entity that would better justify the expenses involved in continuing as an independent publicly traded company.

Availability of Working Capital

To date, we have earned sufficient income from operations to fund periodic operating losses and support efforts to pursue new gamma knife or other types of cancer treatment centers. If the Company experiences operating losses in the future, we will be required to seek additional capital to support continued operations and the development of new centers, but we cannot assure you, however, that we will be able to raise such additional capital as and when required.

Stock Price Volatility; Illiquid Trading Market

Results of operations

2020 Compared to 2019

Patient revenue in 2020 was $3,173,000 as compared to $3,070,000 in 2019. The increase in revenue is primarily due to a higher effective rate per procedure. This is in turn due to a reduction in procedures in contract year 2019/20 due to COVID-19, and in contract year 2020/21, due to the NYU contract ending in March 2021 This effect more than offset the decrease in the number of procedures performed from 2019 (559) to 2020 (462).

Patient expenses in 2020 were $361,000 as compared to $350,000 in 2019. Patient expenses do not vary materially with the number of procedures performed, but are tied to maintenance and other fixed expenses. The increase in patient expenses is due to an increase in supplies to maintain and run the gamma knife and marginally higher maintenance costs.

SG&A decreased by $33,000 or approximately 3% from $1,230,000 in 2019 to $1,197,000 in 2020. This decrease is primarily due to a decease in travel, entertainment, and consulting fees due to the COVID Pandemic. Interest expense decreased to $25,000 in 2020 from $91,000 in 2019, due mainly to lower principal amounts outstanding in 2020. Loss from investments in unconsolidated entities decreased from $1,386,000 in 2019 to $809,000 in 2020, primarily due to lower impairments of amounts advanced to FOP, MOP and CBOP, in turn due to lower advances to those entities in 2020. The Company reported a net income of $533,000 in 2020, as compared to a net income of $142,000 in the prior year, primarily due to the $577,000 reduction of loss from investments in unconsolidated entities. The Company incurred an income tax charge of $323,000 in 2020, compared with $9,000 in 2019.

At December 31, 2020, the Company had working capital of $2,597,000 as compared to $1,043,000 at December 31, 2019. Total assets decreased by $824,000 from 2019 to 2020 principally due to the reduction of the investment in sales-type sublease and amounts due from related parties, partly offset by increased cash held at December 31, 2020. Cash and cash equivalents at December 31, 2020 were $2,030,000 as compared to $1,335,000 at December 31, 2019.

Net cash provided by operating activities was $1,117,000 in 2020 as compared to $1,547,000 in 2019. Net cash used in financing activities was $901,000 in 2020 as compared to $1,397,000 used in 2019 mainly due to lower finance lease principal payments.

For the year ended December 31, 2020, net cash provided by investing activities was $479,000 in 2020 as compared to $334,000 used in 2019, primarily due to $1,113,000 lower net advances to unconsolidated entities.

Critical accounting policies

Estimates and assumptions

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ materially from those estimates.

Revenue Recognition

Prior to October 2018, the Company’s NYU Agreement primarily consisted of an operating lease, and the associated patient revenue from the use of the gamma knife was primarily operating lease income. Following an amendment to the Company’s lease agreement with NYU, effective August 2016, the Company received a $30,000 minimum lease payment from NYU each month. With the exception of these fixed payments, the NYU agreement provided only for contingent rental income based on a tiered fee schedule related to the number of patient procedures and associated thresholds, with the rate per procedure decreasing as more procedures are performed. The Company recognized the contingent rental income and the fixed monthly payments on a systematic basis using an average fee per procedure calculated by estimating the expected number of procedures per contract year which runs from November 1, to the following October 31. Any amounts received in excess of the average fee were considered deferred revenue. At the end of each reporting period, the Company reviewed its estimated revenue for the contract year and adjusted revenue for any material changes in the estimate. At the end of the contract year, the revenue was adjusted to the actual amount received.

In September 2017, USN and NYU entered into an additional amendment to the NYU Agreement, whereby NYU committed to purchase all of the gamma knife equipment at NYU for a purchase price of $2,400,000, consisting of 41 monthly installments of $50,000 commencing at the end of October 2017 and continuing through the end of February 2021, with a final payment of $350,000 on March 31, 2021. Upon receipt of final payment, title to all the equipment at the center passed to NYU.

In October 2018, USN satisfied its obligation to reload the cobalt, and the NYU agreement was reevaluated to be a sales-type sublease between USN, the lessor, and NYU, the lessee. At the inception of a sales-type sublease, the lessor recognizes its gross investment in the sublease, unearned income and sales price. The cost or carrying amount, if different, of the leased property plus any initial direct costs minus the present value of the unguaranteed residual value accruing to the benefit of the lessor, is charged by the lessor against income in the current period. Management has concluded that all fixed future minimum lease payments (“MLPs”) payable by NYU to USN should be included in the investment in sublease. The MLPs include fixed monthly payments of $50,000 through February 2021, and $30,000 through March 2021, as well as a final payment of $350,000 in March 2021. The present value of the MLPs was estimated to be approximately $2,447,000 and was recorded as an investment in sublease effective October 1, 2018. Until the 2021 contract renewal in October of 2020, the patient revenue under the tiered schedule had been considered contingent income under the sales type lease and until October 31, 2020 was recognized on a systematic basis using an average fee per procedure. The Company has recorded patient revenue based on procedures performed at the applicable billing rate for each procedure since November 1, 2020 for the current contract year, since the Company does not expect to exceed the threshold at which billing rates decrease before the completed sale of the equipment on March 31, 2021.

Table of Contents

NYU Maintenance Revenue

The NYU agreement, which ends in March 2021, specifies that USN is obligated to maintain the gamma knife equipment in good operating condition. This maintenance obligation is incurred through the term of the agreement while patient procedures are performed. Usage of the gamma knife machine is directly linked to the maintenance of the machine. USN bills NYU monthly for the maintenance and gamma knife services provided. The portion of the total contract consideration allocated to the maintenance services was $316,000 for 2020 and $316,000 for 2019 and was recognized ratably over each year.

Asset retirement obligations

The Company records liabilities for legal obligations associated with the retirement of tangible long-lived assets based on the estimated future cost of asset retirement obligations discounted to present value and records a corresponding asset and liability on its consolidated balance sheets. The values ultimately derived are based on many significant estimates, including future decommissioning costs, inflation, cost of capital, and market risk premiums. The nature of these estimates requires the Company to make judgments based on historical experience and future expectations. Revisions to the estimates may be required based on such things as changes to cost estimates or the timing of future cash outlays. Any such changes that result in upward or downward revisions in the estimated obligation will result in an adjustment to the related capitalized asset and corresponding liability on a prospective basis. In 2014 the Company estimated that the cost to remove the gamma knife at the end of the agreement to be approximately $620,000. The estimated costs of these obligations are capitalized as costs of the assets subject to the retirement obligations and amortized over the lives of the assets. The Company had previously recorded an asset retirement obligation associated with the gamma knife at NYU. This obligation was derecognized when the NYU agreement was recharacterized as a sales type lease.

Investments in unconsolidated entities

The Company accounts for its investments in unconsolidated entities by the equity method. The Company records its share of such earnings (losses) in the consolidated statements of operations as “Income (loss) from investments in unconsolidated entities”. The carrying value of the Company’s investments in unconsolidated entities is recorded in the consolidated balance sheets. The Company records losses of the unconsolidated entities only to the extent of the Company’s interest in, and advances to, the entities.

Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in the Company’s reports under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, as appropriate, to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures. We do realize that we are a very small company and as a small company with only the officers and directors participating in the day to day management, with the ability to override controls, each officer and director has multiple positions and responsibilities that would normally be distributed among several employees in larger organizations with adequate segregation of duties to ensure the appropriate checks and balances. Because the Company does not currently have a separate chief financial officer, the President performs these functions with the support of one of the Company’s outside directors who assists in the reporting and disclosure process (the “Lead Director”).

Our management evaluated the effectiveness of the design and operation of the Company’s disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934) as of the end of the period covered by this report. Based upon that evaluation, the Company’s President concluded that the Company’s disclosure controls and procedures were not effective as of the end of the period covered by this report for the information required to be disclosed by the Company in the reports it files or submits under the Securities Exchange Act of 1934, as amended, to be recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, due to the material weakness in internal control over financial reporting described below.

Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934). Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles in the United States of America. The Company’s internal control over financial reporting includes those policies and procedures that:

(i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company;

(ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles in the United States of America, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and

(iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company’s assets that could have a material effect on the financial statements.

All internal control systems, no matter how well designed, have inherent limitations and can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation.

Our management, including our President, and assisted by our Lead Director, assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2020. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) in Internal Control-Integrated Framework. A material weakness is a control deficiency, or a combination of control deficiencies in internal controls over financial reporting, such that there is a reasonable possibility that a material misstatement of annual or interim financial statements will not be prevented or detected on a timely basis. In connection with the assessment described above, management has identified the following material weakness as of December 31, 2020: the Company did not maintain sufficient qualified personnel with the appropriate level of knowledge, experience and training in the application of accounting principles generally accepted in the United States of America and in internal controls over financial reporting commensurate with its financial reporting requirement. Specifically, effective controls were not designed and in place to ensure that the Company maintained, or had access to, appropriate resources with adequate experience and expertise in the area of financial reporting for transactions such as investments in unconsolidated entities, related party receivables, impairments, lease accounting, and income taxes. The Company is in the process of developing efficient approaches to remediate this material weakness.

Table of Contents

Changes in Internal Control over Financial Reporting

Management is in the process of reviewing and developing plans to remediate the material weakness identified above. Otherwise, there have not been any changes in the Company’s internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the fiscal quarter ended December 31, 2020 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders

U.S. NeuroSurgical Holdings, Inc.

Rockville, Maryland

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of U.S. NeuroSurgical Holdings, Inc. and Subsidiaries (the “Company”) as of December 31, 2020 and 2019, and the related consolidated statements of operations, stockholders’ equity, and cash flows for each of the years in the two-year period ended December 31, 2020, and the related notes (collectively referred to as the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2020 and 2019, and the results of their operations and their cash flows for each of the years in the two-year period ended December 31, 2020, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matters

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of criti cal audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Recognition of income under the Company’s contract with New York University

As outlined in Note B[2], in order to recognize revenue under its contract with New York University (“NYU”) the Company is required to allocate all consideration payable by NYU between fixed payments attributable to the Company’s investment in sales type lease, contingent consideration based on usage of the leased equipment, and reimbursement of maintenance costs incurred. The Company is also required to determine the expected consideration earned for each patient procedure performed due to the contingent consideration being based on a tiered billing schedule.

Significant judgment is exercised by the Company when determining the contingent consideration to be earned under the NYU contract, and includes the following considerations:

•

Total number of procedures to be performed in each contract year.

•

Expected average resulting rate per procedure earned.

Our audit procedures related to testing the Company’s estimates and allocation of revenue between the investment in sales type lease, contingent lease consideration and maintenance revenue, and determination of income to be recognized included the following:

•

We assessed the design and implementation of internal controls relating to the Company’s recognition of income and collection of receivables under the NYU contract.

•

We evaluated management’s accounting policies related to income recognition and investment in sales type lease. This included evaluating management’s methodology for allocating total consideration under the NYU contract between the investment in sales type lease, contingent consideration and maintenance revenue.

•

We confirmed all billings made to NYU during 2020 with a representative at NYU, and agreed those billings to underlying usage reports.

•

We tested cash receipts for substantially all billings generated during 2020.

•

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note A – Organization and Business

U.S. NeuroSurgical, Inc. a Delaware corporation, was organized in July 1993 for the purpose of owning and operating stereotactic radiosurgery centers, utilizing the gamma knife technology. USN holds an interest in one gamma knife center on the premises of New York University Medical Center (“NYU”) in New York, New York. Management continues to explore opportunities to organize and participate in additional gamma knife centers. USN’s business strategy is to provide a mechanism whereby hospitals, physicians, and patients can have access to gamma knife treatment capability, a high capital cost item. USN provides the gamma knife to medical facilities on a “cost per treatment” basis. USN holds an interest in the gamma knife unit and is reimbursed by the facility where it is housed, based on utilization.

During the fourth quarter of 2007, USN formed a wholly-owned subsidiary, USN Corona, Inc. (“USNC”), to carry investments in Corona Gamma Knife, LLC and NeuroPartners, LLC. Those investments were formed to develop and manage a gamma knife center at San Antonio Regional Hospital in Upland, California. (See Note C[1])

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 (Intensity Modulated Radiation Therapy) and IGRT (Image Guided Radiation Therapy) capabilities. In 2010, the Company formed Florida Oncology Partners, LLC (“FOP”) in partnership with local physicians and other investors. USNC owns a 24% interest in the venture. FOP’s first center was located in Miami, Florida and opened in the second quarter of 2011. The Company entered into an arrangement to sell the center to 21 ^st Century Oncology in December 2015. The sale has not occurred as of December 31, 2020. (See Note C[2])

During 2011, the Company participated in the formation of Boca Oncology Partners RE, LLC (“BOPRE”), for the purpose of acquiring an interest in Boca West, IMP, LLC, (“Boca West, IMP”) which owns a medical office building. (See Note C[3]).

In 2015, Medical Oncology Partners LLC (“MOP”), was formed in partnership with local physicians and other investors. MOP was established to acquire a 100% equity interest in United Oncology Medical Associates of Florida, LLC (“UOMA”). USNC was not a member of MOP at the time of its formation, as it was not able to participate in MOP’s formation due to the fact that USNC was not a physician. An application was filed for a waiver and on December 22, 2016, USNC was cleared to become a part owner of MOP. USNC currently owns 35.83% of MOP. (See Note C[4])

On September 3, 2015, pursuant to the Agreement and Plan of Reorganization (the “Merger Agreement”), dated as of September 3, 2015, by and among USN, Holdings and U.S. NeuroSurgical Merger Sub, Inc. (“Merger Sub”), the Company adopted a new holding company organizational structure whereby USN is now a wholly owned subsidiary of Holdings. This structure did not result in any changes to the assets or operations of the Company, but management believes that it will create a more flexible framework for possible future transactions and organizational and operational adjustments.

The holding company organizational structure was effected by a merger (the “Merger”) conducted pursuant to Section 251(g) of the Delaware General Corporation Law (the “DGCL”), which provides for the formation of a holding company structure without a vote of the stockholders of the constituent corporations. Because the holding company organizational structure occurred at the parent company level, the remainder of the Company’s subsidiaries, operations and customers were not affected by this transaction.

U.S. NEUROSURGICAL HOLDINGS, INC. AND SUBSIDIARIES

Following the Merger, Holdings’ common stock continued to trade on the over-the-counter market and continued to be quoted on the OTC Markets under the same symbol, “USNU.” The conversion of shares of capital stock under the Merger Agreement occurred without an exchange of physical certificates. Accordingly, physical certificates formerly representing shares of outstanding capital stock of USN are deemed to represent the same number of shares of capital stock of Holdings.

Late in 2016, FOP took initial steps toward the development of a new radiation therapy center in Homestead, Florida. However, 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. CB Oncology Partners, LLC (“CBOP”) was organized on September 1, 2017 to acquire the assets and rights in this new center from FOP. USNC owns a 28.58% interest in CBOP.

The Company, through the formation of noncontrolling interests in unconsolidated joint ventures, is currently exploring other opportunities for the establishment of cancer centers using IMRT and/or IGRT in Florida and other parts of the U.S.

The recent outbreak of the novel coronavirus COVID-19 has spread across the globe and has been declared a public health emergency by the World Health Organization and a National Emergency by the President of the United States. Most states and municipalities in the U.S., including New York, California, and Florida, have taken aggressive measures to reduce the spread of the disease, including limiting non-essential gatherings of people, ceasing all non-essential travel, ordering certain businesses and government agencies to cease non-essential operations at physical locations and issuing “shelter-in-place” orders, which direct individuals to shelter at their places of residence (subject to limited exceptions). Across the healthcare industry, resources are being prioritized for the treatment and management of the outbreak. Consequently, there are delays in delivering Gamma Knife and other radiation therapy treatments. In addition, the COVID-19 pandemic poses the risk that the Company and its employees, contractors, customers, government and third party payors and others may be prevented from conducting business activities for an indefinite period of time, including due to spread of the disease within these groups or due to shutdowns that have been and may continue to be requested or mandated by governmental authorities.

U.S. NEUROSURGICAL HOLDINGS, INC. AND SUBSIDIARIES

While the healthcare treatments that are provided by the Company are generally critical to the well-being of the patients it serves, a sustained COVID-19 pandemic, and continued measures by the government and industry to contain the pandemic, could negatively impact results for the following reasons: (i) operations at medical facilities, including those operated by the Company, could be subject to reduced operation or prolonged closure; (ii) medical facilities may defer Gamma Knife and other cancer therapy treatments for non-urgent patient cases in order to allocate resources to the care of patients with COVID-19; (iii) patients may defer or cancel treatments due to real or perceived concerns about the potential spread of COVID-19 in a medical facility setting; (iv) the outbreak could materially impact operations for a sustained period of time due to the current travel bans and restrictions, quarantines, shelter-in-place orders and shutdowns; and/or (v) members of the Company’s workforce may become ill or have family members who are ill and are absent as a result, or they may elect not to come to work due to the illness affecting others in our office or facilities.

Note B - The Company and its Significant Accounting Policies

[1]	Basis of presentation and consolidation:

The consolidated financial statements include the accounts of Holdings and its wholly-owned subsidiaries, USN, USNC and U.S. NeuroSurgical Physics, Inc. All significant intercompany balances and transactions have been eliminated in consolidation.

[2]	Revenue recognition:

In May 2014 and in subsequent updates, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers (“Topic 606”) to clarify the principles for recognizing revenue. Topic 606 replaced Topic 605, which was the revenue recognition standard in effect through December 31, 2017. Topic 606 amended existing revenue recognition guidance and required more detailed disclosures to enable users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. We adopted Topic 606 on January 1, 2018, using the modified retrospective basis and applied it to the Company’s sole contract with NYU at the date of adoption. The adoption of Topic 606 did not result in any significant changes to our historic revenue accounting. Our revenue is primarily generated from a leasing arrangement with New York University, which is not within the scope of Topic 606, and from the sale of maintenance services with a single performance obligation, under which revenue is recognized in a similar manner to the prior revenue standard. No cumulative change to retained earnings was required upon adoption of Topic 606.

As discussed below, following the adoption of Topic 606, we recognized revenue in accordance with two different accounting standards: 1) Topic 606 and 2) Accounting Standards Codification (“ASC”) Topic 840, Leases (which addresses lease accounting). We adopted ASC Topic 842, Leases which replaced Topic 840, on January 1, 2019. There were no significant changes to our revenue accounting upon adoption of Topic 842 (see significant account policies, item 17, for further discussion).

F-10

Table of Contents

U.S. NEUROSURGICAL HOLDINGS, INC. AND SUBSIDIARIES

Under Topic 606, the core principle is to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Topic 606 defines a five-step process to accomplish this objective, including identifying the contract with the customer and the performance obligations within the contract, determining the transaction price including estimates of any variable consideration, allocating the transaction price to each separate performance obligation, and recognizing revenue as the Company satisfies each performance obligation. A performance obligation is a promise in a contract to transfer a distinct good or service to a customer and is the unit of account under Topic 606. We recognize revenue when we satisfy a performance obligation by transferring control over a product or service to a customer.

The discussion below addresses our primary types of revenue as categorized by the applicable accounting standards.

NYU Lease revenue:

Prior to October 2018, the Company’s Gamma Knife Neuroradiosurgery Equipment Agreement with NYU (“NYU Agreement”) primarily consisted of an operating lease, and the associated patient revenue from the use of the gamma knife was primarily operating lease income. Following an amendment to the Company’s lease agreement with NYU, effective August 2016, the Company received a $30,000 minimum lease payment from NYU each month. With the exception of these fixed payments, the NYU agreement provided only for contingent rental income based on a tiered fee schedule related to the number of patient procedures and associated thresholds, with the rate per procedure decreasing as more procedures are performed. The Company recognized the contingent rental income and the fixed monthly payments on a systematic basis using an average fee per procedure calculated by estimating the expected number of procedures per contract year which runs from November 1, to the following October 31. Any amounts received in excess of the average fee were considered deferred revenue. At the end of each reporting period, the Company reviewed its estimated revenue for the contract year and adjusted revenue for any material changes in the estimate. At the end of the contract year, the revenue was adjusted to the actual amount received or receivable.

In September 2017, USN and NYU entered into an additional amendment to the NYU Agreement, whereby NYU committed to purchase all of the gamma knife equipment at the NYU Medical Center for a purchase price of $2,400,000, consisting of 41 monthly installments of $50,000 commencing at the end of October 2017 and continuing through the end of February 2021, with a final payment of $350,000 on March 31, 2021. Upon receipt of final payment, title to all the equipment at the center passed to NYU.

In October 2018, USN satisfied its obligation to reload the cobalt, and the NYU agreement was re-evaluated to be a sales-type sublease between USN, the lessor, and NYU, the lessee. At the inception of a sales-type sublease, the lessor recognizes its gross investment in the sublease, unearned income and sales price. The cost or carrying amount, if different, of the leased property plus any initial direct costs minus the present value of the unguaranteed residual value accruing to the benefit of the lessor, is charged by the lessor against income in the current period. Management has concluded that all fixed future minimum lease payments (“MLPs”) payable by NYU to USN should be included in the investment in sublease. These MLPs include fixed monthly payments of $50,000 through February 2021 and $30,000 through March 2021, as well as a final payment of $350,000 in March 2021. The present value of the MLPs was estimated to be approximately $2,447,000 and was recorded as an investment in sublease effective October 1, 2018. Until the 2021 contract renewal in October of 2020, the patient revenue under the tiered schedule had been considered contingent income under the sales type lease and was recognized on a systematic basis using an average fee per procedure, until October 2020 The Company has recorded patient revenue based on procedures performed at the applicable billing rate for each procedure since November 1, 2020 (the current contract year) since the Company does not expect to exceed the threshold at which billing rates decrease before the completed sale of the equipment on March 31, 2021.

U.S. NEUROSURGICAL HOLDINGS, INC. AND SUBSIDIARIES

NYU Maintenance Revenue:

The NYU agreement, which ended in March 2021, specifies that USN is obligated to maintain the gamma knife equipment in good operating condition. This maintenance obligation is incurred through the term of the agreement while patient procedures are performed. Usage of the gamma knife machine is directly linked to the maintenance of the machine. USN bills NYU monthly for the maintenance and gamma knife services provided. The portion of the total contract consideration allocated to the maintenance services was $316,000 for 2020 and $316,000 for 2019, and was recognized ratably over each year.

[3]	Cash and cash equivalents:

The Company considers all highly liquid debt instruments purchased with a maturity of three months or less to be cash equivalents.

[4]	Accounts receivable

Accounts receivable only include amounts owed to the Company from the NYU Agreement. The Company considers these accounts receivable to be collectible at December 31, 2020 and 2019. The Company continuously monitors its relationship with NYU and would provide a charge to income, if necessary, to absorb any expected losses.

[5]	Investments in unconsolidated entities:

The Company accounts for its investments in unconsolidated entities by the equity method. The Company records its share of such earnings (loss) in the Consolidated Statement of Operations as “Loss from investments in unconsolidated entities”. The carrying value of the Company’s investments in unconsolidated entities is recorded in the Consolidated Balance Sheets. The Company records losses of the unconsolidated entities only to the extent of the Company’s interest in and advances to the entities. As such, the recorded balance of FOP, MOP, and CBOP have been taken to zero.

In August 2016, the FASB issued ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments, which in part requires entities to assess whether distributions of cash from unconsolidated entities represent a return on the investment or a return of the investment, to appropriately classify the distributions in the statement of cash flows. Although the ASU is effective in the first quarter of 2018, we early adopted the guidance in the first quarter of 2017 due to the ongoing applicability of the new standard to the Company’s consolidated financial statements. We made an accounting policy election to use the cumulative earnings approach to determine that the distributions were returns on the investment and accordingly classified them as operating cash flows. Under the cumulative earnings approach, distributions received from the unconsolidated entity are presumed to be a return on the investment unless the distributions received by the investor, less distributions received in prior periods that were deemed to be returns of investment, exceed cumulative equity in earnings recognized by the investor.

[6]	Long-lived assets:

The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable.

[7]	Depreciation and amortization:

Up until the determination that the Company’s arrangement with NYU is a sales type lease, effective October 1, 2018, the Company’s gamma knife was depreciated on the straight-line method over an estimated useful life of 7 years. Leasehold improvements were also amortized on the straight-line method over 7 years, which is the shorter of the useful life, or the life of the NYU Agreement. Office furniture and computers are being depreciated on the straight-line method over their estimated useful lives ranging from 3 to 7 years.

U.S. NEUROSURGICAL HOLDINGS, INC. AND SUBSIDIARIES

[8]	Asset retirement obligations:

[9]	Capital lease obligations:

Effective January 1, 2019, the Company adopted ASU 2016-02, Leases, and the Company’s leases previously classified as capital leases, were determined to be finance leases.

[10]	Guarantees:

The Company recognizes a liability at the fair value of the obligation at the inception of a financial guarantee contract. The initial liability is subsequently reduced as the Company is released from exposure under the guarantee. If it becomes probable that the Company will have to perform on a guarantee, a separate liability is accrued if it is reasonably estimable, based on the facts and circumstances at that time. The Company reverses the fair value liability only when there is no further exposure under the guarantee.

[11]	Income taxes:

Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets or liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Valuation allowances are established when necessary to reduce tax assets to amounts more likely than not to be realized.

The Company has adopted the accounting provisions for Accounting for Uncertainty in Income Taxes . (Topic 740) This accounting provision provides a comprehensive model for how the Company should recognize, measure, present, and disclose in its financial statements uncertain tax positions that the Company has taken or expects to take on its tax returns. If applicable, the Company records interest and penalties as a component of income tax expense, The Company had no uncertain material tax positions at December 31, 2020 and 2019. Tax years from January 1, 2017 to the current year remain open for examination by federal and state tax authorities.

[12]	Earnings per share:

Earnings per share are computed by dividing earnings available to common stockholders by the weighted average shares outstanding for the period. There were no common stock equivalents during 2020 and 2019, and therefore, no potential dilution for the periods presented.

F-13

Table of Contents

U.S. NEUROSURGICAL HOLDINGS, INC. AND SUBSIDIARIES

[13]	Advertising costs:

The Company follows the policy of charging the costs of advertising to expense as incurred. There were no advertising costs in 2020 and 2019.

[14]	Estimates and assumptions:

[15]	Fair values of financial instruments:

The estimated fair value of financial instruments has been determined based on available market information and appropriate valuation methodologies. The carrying amounts of cash and cash equivalents, accounts receivable, other current assets, due from or to related parties, and accounts payable approximate fair value at December 31, 2020 and 2019 because of the short maturity of these financial instruments. The carrying values of the notes receivable and the obligations under finance leases, approximate fair value because the interest rates on these instruments approximate the market rates at December 31, 2020 and 2019.

[16]	Credit risk:

At times, the Company may have cash and cash equivalents at a financial institution in excess of insured limits. The Company places its cash and cash equivalents with high credit quality financial institutions whose credit ratings are monitored by management to minimize credit risk. Accounts receivable consist of amounts due from the medical centers. Historically, credit losses on accounts receivable have not been significant. At December 31, 2020 and 2019, substantially all of the Company’s accounts receivable were due from one customer, NYU.

[17]

Leases:

In February 2016, the FASB issued ASU 2016-02, Leases (“Topic 842”) to increase transparency and comparability among organizations by requiring (1) recognition of lease assets and lease liabilities on the balance sheet and (2) disclosure of key information about leasing arrangements. Some changes to the lessor accounting guidance were made to align both of the following: (1) the lessor accounting guidance with certain changes made to the lessee accounting guidance and (2) key aspects of the lessor accounting model with revenue recognition guidance. Topic 842 was effective for fiscal years and interim periods beginning after December 15, 2018. A modified retrospective approach is required for adoption for all leases that exist at or commence after the date of initial application with an option to use certain practical expedients.

We adopted the provisions of Topic 842, as amended, as of January 1, 2019. The adoption of Topic 842 had a material impact on the Company’s Consolidated Balance Sheets due to the recognition of certain right-of-use (“ROU”) assets and lease liabilities. Although a significant amount of our revenue is now accounted for under Topic 842, this guidance did not have a material impact on our Consolidated Statements of Operations or Cash Flows. Because of the transition method we used to adopt Topic 842, Topic 842 will not be applied to periods prior to adoption and the adoption of Topic 842 had no impact on our previously reported results, or on opening equity at January 1, 2019.

The Company determines if an arrangement is a lease at its inception. The Company’s current operating lease relates to office space and is discussed in Note K. The Company’s finance lease obligations and sales-type sublease are related to the NYU gamma knife. The Company’s previously-recorded capital lease obligations addressed in Note G to the consolidated financial statements were accounted for as finance lease obligations upon adoption of Topic 842. The sales-type sublease is discussed in Note E.

Under Topic 842, operating leases result in the recognition of ROU assets and lease liabilities on the balance sheet. ROU assets represent our right to use the leased asset for the lease term and lease liabilities represent our obligation to make lease payments. Under Topic 842, operating lease ROU assets and lease liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. The Company’s operating lease does not provide an implicit rate; therefore, upon adoption of Topic 842, the Company used its estimated incremental borrowing rate at the commencement date to determine the present value of lease payments. The operating lease ROU assets include any initial lease payments made and exclude lease incentives received. The lease terms may include options to extend or terminate the lease that are reasonably certain to be exercised. Lease expense under Topic 842 is recognized on a straight-line basis over the lease term.

Note C - Investments in Unconsolidated Entities

[1]	The Southern California Regional Gamma Knife Center

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 is a 20% owner of NeuroPartners LLC and owns 39% of CGK.

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. The Company continues to be a 20% guarantor on the new lease and expects any potential obligations from this guarantee would be reduced by the recovery of the related collateral, and thus expects any exposure from this guarantee to be remote.

At December 31, 2020 and 2019, the Company’s recorded investment of NeuroPartners LLC and CGK was $26,000 and $0, respectively. During the years ended December 31, 2020 and 2019, the Company’s equity in earnings of NeuroPartners LLC and CGK was $124,000 and $92,000, respectively. At December 31, 2020 and 2019, amounts due from related parties was $9,000 and $31,000, respectively, including $20,000 of distributions receivable at December 31, 2019. These distributions were received in 2020.

[3]	Boca Oncology Partners

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.

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.

Note D - Agreement with New York University on Behalf of New York University Medical Center

In November 1996, USN entered into a Gamma Knife Neuroradiosurgery Equipment Agreement with NYU, (the “NYU Agreement”) for a period of seven years (the “term”), with an option for NYU to extend the term for successive three-year periods or to purchase the gamma knife equipment at an appraised market value price. USN had the ability to negotiate the purchase price and upon failure of the parties to agree could request that the facility be closed. All costs associated with closing and restoring the facility to its original condition were the responsibility of USN. The NYU agreement, among other matters, required USN to provide (i) the use of the gamma knife equipment to NYU, (ii) training necessary for the proper operation of the gamma knife equipment, (iii) sufficient supplies for the equipment, (iv) the repair and maintenance of the equipment, (v) all basic hardware and software upgrades to the equipment and, (vi) an uptime guarantee. In return, NYU paid USN a scheduled fee based on the number of patient procedures performed.

In 2004, the NYU agreement was extended through March 2009. In 2008, the NYU agreement was extended for an additional 12 years through March 2021. To secure this extension, USN agreed to install a new gamma knife PERFEXION model. The new equipment and certain space improvements, costing $3,742,000 in total, was financed through a seven-year lease arrangement. The amendment provides for a payment to USN of a flat fee for each patient procedure performed.

The Company entered into a six-year lease of $4.7 million for the purchase of the replacement equipment and associated leasehold improvements. The Company entered into a second two-year lease of $250,000 for the cost of the construction required at the relocated site which was repaid in July 2016.

In 2016, USN entered into an agreement with Elekta for the installation of new ICON imaging technology for the NYU Gamma Knife equipment with a total cost, including sales taxes, of $816,000. This ICON technology was installed during the month of July 2016 and the gamma knife center reopened on August 5, 2016. The Company entered into a four-year lease for $879,000 to finance the acquisition of the ICON technology and associated installation costs. A monthly maintenance agreement commenced a year after the installation date for $6,000 per month. The two parties also agreed for USN to receive a fixed monthly payment of $30,000 for the remaining term of the agreement through March 2021.

In September 2017, USN and NYU entered into an additional amendment to the NYU Agreement, whereby NYU committed to purchase all of the gamma knife equipment at the NYU Medical Center for a purchase price of $2,400,000, with 41 monthly installments of $50,000 from October 2017 through February 2021, and a final payment of $350,000 on March 31, 2021. Previously, the NYU agreement ended on March 17, 2021 and NYU had an option to purchase the gamma knife equipment at the estimated future value of the equipment at that time. In June 2017, the Company obtained an independent estimate of $2,570,000 for the estimated future fair value of the equipment in March 2021. The Company believes that the accelerated payments amounting to $2,400,000 represent fair consideration considering all aspects of the transaction.

The Company continues to be responsible for the maintenance and insurance for the gamma knife equipment at the NYU facility through the contract period and continues to be reimbursed for use of the gamma knife based on a fee per procedure performed with the equipment. NYU provides the medical and technical staff to operate the facility.

With the September 2017 amendment, the Company became obligated to reload the cobalt for the gamma knife at its own expense and bear the cost of site work involved in reloading the cobalt, up to a maximum of $1,088,000. In July 2018, USN entered into an agreement with Elekta for the cobalt reload on the NYU gamma knife equipment with a cost, including sales taxes, of $925,000. This cobalt reload occurred in July 2018, and the gamma knife center reopened on August 6, 2018. The Company obtained lease financing of $833,000 to partially finance the reload of the cobalt, and paid the remaining balance directly to Elekta. In addition, the Company incurred costs of $578,000 to install the new cobalt to be paid directly to the contractor. All cobalt related costs were finalized by October 1, 2018 and totaled $1,503,000. As a result of the Company satisfying its obligation to reload the cobalt, the agreement with NYU met the criteria to be classified as a sales type lease. In addition, the Company is now no longer obligated to restore the NYU facility to its original condition. Accordingly, all related assets and the asset retirement obligation were derecognized effective October 1, 2018.

NYU Revenue Recognition:

The Company derived patient revenue from the NYU center of $3,173,000 and $3,070,000 in 2020 and 2019, respectively, consisting of lease revenue of $2,857,000 and $2,754,000 and maintenance revenue of $316,000 for both 2020 and 2019.

NYU Accounts Receivable and Contract Balances:

Accounts receivable presented in the Company’s Consolidated Balance Sheet represents an unconditional right to consideration from NYU. The NYU Agreement is primarily a leasing arrangement and does not have other contract assets or contract liabilities, other than associated deferred revenue.

Accounts receivable total $346,000 and $356,000 at December 31, 2020 and 2019 respectively.

Note E – Investment in Sublease

The September 2017 amendment to the NYU Agreement provided for NYU to purchase all of the gamma knife equipment at the NYU Medical Center for a purchase price of $2,400,000, consisting of 41 monthly installments of $50,000 commencing at the end of October 2017 and continuing through the end of February 2021, with a final payment of $350,000 on March 31, 2021. Upon receipt of final payment, title to all the equipment at the center passes to NYU. This amendment also required USN to reload the cobalt in the gamma knife and to reimburse NYU for certain costs NYU incurred due to the cobalt reload.

Effective October 1, 2018, USN completed the reload of the cobalt and associated costs for a total cost of $1,503,000. With the removal of the cobalt contingency, the NYU agreement was reevaluated to be a sales-type sublease between USN, the lessor, and NYU, the lessee. At the inception of a sales-type sublease, the lessor recognizes its gross investment in the sublease, unearned income and sales price. The initial sales price of $2,400,000 at September 2017 was valued at $2,447,000 at October 1, 2018, using the present value of future cash flows. The cost or carrying amount, if different, of the leased property plus any initial direct costs minus the present value of the unguaranteed residual value accruing to the benefit of the lessor, is charged by the lessor against income in the current period.

The monthly fixed payments under the NYU Agreement amortize the investment in sublease until title passed to NYU on March 31, 2021. The NYU Agreement requires NYU to make monthly fixed payments of $30,000 and $50,000 through February 2021 with a final fixed payment of $380,000 ($30,000 and $350,000) in March 2021.

Future minimum lease payments to be received as of December 31, 2020 under the investment in sublease are as follows:

Year Ending December 31,

2021		540,000

Note F – Property and Equipment

Effective October 1, 2018, when the NYU agreement was determined to be a to be a sales-type sublease between USN, the lessor, and NYU, the lessee, all of the property and equipment held by the Company was derecognized (Note E). As a result, no assets included in property and equipment remain on the Company’s Consolidated Balance Sheets at December 31, 2020 and 2019.

Note G - Obligations Under Finance Leases

In 2009, the Company installed a PERFEXION model gamma knife at the NYU center with a seven-year lease from Elekta Capital. The amount financed, covering the cost of the new gamma knife equipment and certain space improvements, was approximately $3,742,000 in total. This lease became payable as a result of damage sustained at the NYU facility in October 2012, due to flooding from Hurricane Sandy, and the remainder of the balance due was paid in January 2013. In 2013, the Company entered into a modification of the above capital lease agreement to finance the new gamma knife installation, the related construction costs and the removal costs of the old equipment for approximately $4.7 million at an interest rate of 4.49% to be repaid beginning in May 2014 over 72 months with no payments for the first three months and $78,000 monthly payments thereafter through May 2020. The Company entered into another capital lease in 2014 to finance a further $250,000 of installation and construction costs, which was repaid over 24 months. In 2016, the Company entered into a capital lease in the amount of $879,000 at an interest rate of 4.45% to finance the installation of the ICON technology for the NYU Gamma Knife equipment to be repaid over 48 months with $20,000 monthly payments beginning October 2016 through September 2020. In October 2018, the Company entered into a capital lease in the amount of $833,000 at an interest rate of 5.85% to partially finance the reload of the cobalt to be repaid over 30 months with $30,000 monthly payments from October 2018 through March 2021.

As discussed in Note B, the Company adopted Topic 842 on January 1, 2019. Upon adoption of Topic 842, the capital lease obligations are accounted for as finance lease obligations with no significant change to how the obligations were accounted for.

The obligations under the finance leases are as follows:

	December 31,
	2020			2019

Effective October 1, 2018, when the NYU agreement was determined to be a to be a sales-type sublease between USN, the lessor, and NYU, the lessee, all of the leased property and equipment held by the Company was derecognized (Note E). As a result, no leased assets included in property and equipment remain on the Company’s Consolidated Balance Sheets at December 31, 2020 and 2019.

Future payments as of December 31, 2020 on the finance leases are as follows:

Note H – Asset Retirement Obligations

When the agreement with NYU relating to the restored gamma knife was finalized in 2014, the Company estimated the cost to remove the gamma knife at the end of the agreement in 2021 to be $620,000. Effective October 1, 2018, when the NYU agreement was determined to be a sales-type sublease between USN, the lessor, and NYU, the lessee, the asset retirement obligation was derecognized (Note E). As a result, no asset retirement obligation remains on the Company’s Consolidated Balance Sheets at December 31, 2020 and 2019.

[2]	NYU Gamma Knife:

Capital Lease Obligations (Notes D and G):

In 2009, the Company installed a new gamma knife PERFEXION model at the NYU Medical Center. This new equipment and certain space improvements, costing approximately $3,742,000 in total, were financed through a seven-year lease arrangement. This PERFEXION equipment was recorded as a total loss as a result of flooding from Hurricane Sandy in October 2012.

In early 2014, the Company entered into a six-year lease in the amount of $4.7 million for the purchase of the replacement equipment and associated leasehold improvements. The first payment of $78,000 was made on September 1, 2014, including $18,000 of interest, and the final payment was made in May 2020.

The Company entered into a second capital lease in 2014 to finance an additional $250,000 of installation and construction costs, which was repaid in July 2016.

In April 2016 the Company obtained lease financing of $879,000 to finance the acquisition of the ICON technology for the NYU Gamma Knife and associated installation costs. Monthly lease payments of $20,000 began in October 2016, and the final payment was made in September 2020.

In October 2018, the Company entered into an additional capital lease in the amount of $833,000 to partially finance the reload of the cobalt to be repaid over 30 months with the final payment due in March 2021.

Maintenance Contract:

The new gamma knife installed in April 2014 included a one-year warranty. The new maintenance agreement began in April of 2015. The monthly payment increased from $20,000 to $26,000 effective August 2017, due to the addition of the ICON maintenance agreement and is in effect for 5 years.

[3]	Guarantees:

USNC is a 20% guarantor on NeuroPartners, LLC’s lease, terminating March 2021, with respect to the gamma knife equipment, cobalt reload and associated construction, and certain leasehold improvements located at the Southern California Regional Gamma Knife Center at SARH in Upland, California. The outstanding balance on the lease obligations was $60,000 and $421,000 at December 31, 2020 and 2019, respectively.

Holdings is a guarantor of the full amount of the outstanding loan with BB&T Bank entered into in 2017, as described In Note C[2]. The outstanding balance on this loan was $3,066,000 and $3,273,000 at December 31, 2020 and 2019, respectively.

USNC was a 10% guarantor on 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. The Company was released from this guaranty when the mortgage was refinanced in April of 2020.

The Company expects any potential obligations from these guarantees to be reduced by the recoveries of the respective collateral and has recorded a liability of $11,000 at December 31, 2020 and 2019. See Note C for further discussion of investments in unconsolidated entities.

[4]	Product liability:

Although USN does not directly provide medical services, it has obtained professional medical liability insurance, and has general liability insurance as well. USN’s professional medical liability and general liability policies have limits of $3 million each. The Company believes that its insurance is adequate for providing treatment facilities and non-medical services, although there can be no assurance that the coverage limits of such insurance will be adequate or that coverage will not be reduced or become unavailable in the future.

Note L - Employees’ IRA Plans

The Company has established a Company IRA covering all employees. The plan allows participants to make pre-tax contributions and the Company may, at its discretion, match certain percentages of the employee contribution. Amounts contributed to the plan are deposited into a trust fund administered by independent trustees. The Company made a discretionary matching IRA contribution of $14,000 for each of the years ended December 31, 2020 and 2019.
