NOTE 2 – ACCOUNTING POLICIES

Use of estimates in the preparation of financial statements – In preparing the consolidated financial statements in conformity with accounting principles generally accepted in the United States of America, management makes estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the consolidated financial statements, as well as the reported amounts of revenues and expenses during the reporting period. Significant accounting estimates reflected in the Company’s consolidated financial statements include the estimated useful lives of fixed assets and its salvage values, revenues and costs of sales for turn-key and revenue sharing arrangements.  Actual results could differ from those estimates.

Advertising costs – The Company expenses advertising costs as incurred. Advertising costs were $211,000 and $237,000 during the years ended December 31, 2021 and 2020. Advertising costs are recorded in other direct operating costs and sales and administrative costs in the consolidated statements of operations.

Cash and cash equivalents – The Company considers all liquid investments with original maturities of three months or less at the date of purchase to be cash equivalents. Restricted cash is not considered a cash equivalent for purposes of the consolidated statements of cash flows.

Restricted cash – Restricted cash represents the minimum cash that must be maintained in GKF to fund operations, per the subsidiary’s operating agreement, the minimum cash that must be maintained by GKF per it’s financing agreement with DFC, and the minimum cash that must be maintained in Orlando per the subsidiary’s financing agreement.  The minimum cash requirement in Orlando was released when the Company refinanced its debt and finance lease portfolio in the second quarter of 2021.  See further discussion at Note 6 - Long Term Debt.

Business and credit risk – The Company maintains its cash balances, which exceed federally insured limits, in financial institutions. The Company believes it is not exposed to any significant credit risk on cash, cash equivalents. The Company monitors the financial condition of the financial institutions it uses on a regular basis.

All of the Company’s revenue was provided by seventeen and eighteen customers in 2021 and 2020, respectively. One customer accounted for approximately 34% and 35% of the Company’s total revenue in 2021 and 2020. At December 31, 2021, two customers each individually accounted for 31% and 10% of total accounts receivable, respectively. At December 31, 2020, four customers each individually accounted for 11%, 11%, 11% and 20% of total accounts receivable, respectively. The Company performs credit evaluations of its customers and generally does not require collateral. The Company has not experienced significant losses related to receivables from individual customers or groups of customers in any particular geographic area.

All of the Company’s radiosurgery devices have been purchased through Elekta, to date. However, there are other manufacturers that also make radiosurgery devices.

Accounts receivable and doubtful accounts – Accounts receivable are recorded at net realizable value. An allowance for doubtful accounts is estimated based on historical collections plus an allowance for probable losses. Receivables are considered past due based on contractual terms and are charged off in the period that they are deemed uncollectible. Recoveries of receivables previously charged off are offset against bad debt expense when received.

Non-controlling interests - The Company reports its non-controlling interests as a separate component of shareholders’ equity. The Company also presents the consolidated net income and the portion of the consolidated net income allocable to the non-controlling interests and to the shareholders of the Company separately in its consolidated statements of operations.

Property and equipment – Property and equipment are stated at cost less accumulated depreciation. Depreciation for Gamma Knife and other equipment is determined using the straight-line method over the estimated useful lives of the assets, which for medical and office equipment is generally 3 – 10 years, and after accounting for salvage value on the equipment where indicated. Salvage value is based on the estimated fair value of the equipment at the end of its useful life. The Company acquired a building as part of the Acquisition in June 2020. Depreciation for buildings is determined using the straight-line method over 20 years. The Company determines salvage value based on the estimated fair value of the equipment at the end of its useful life. As of   April 1, 2021, the Company reduced its estimate for salvage value for nine of its domestic Gamma Knife Perfexion units. The net effect of this change in estimate for the year ended  December 31, 2021, was a decrease in net income of approximately $342,000 or $0.06 per diluted share. This change in estimate will also impact future periods.

Depreciation for PBRT and related equipment is determined using the modified units of production method, which is a function of both time and usage of the equipment. This depreciation method allocates costs considering the projected volume of usage through the useful life of the PBRT unit, which has been estimated at 20 years. The estimated useful life of the PBRT unit is consistent with the estimated economic life of 20 years.

The Company capitalizes interest incurred on property and equipment that is under construction, for which deposits or progress payments have been made. When a rate is not readily available, imputed interest is calculated using the Company’s incremental borrowing rate. The interest capitalized for property and equipment is the portion of interest cost incurred during the acquisition periods that could have been avoided if expenditures for the equipment had not been made. The Company capitalized interest of $0 and $119,000 in 2021 and 2020, respectively, as costs of medical equipment.

The Company leases Gamma Knife and radiation therapy equipment to its customers under arrangements accounted for as operating leases. At December 31, 2021, the Company held equipment under operating lease contracts with customers with an original cost of $72,972,000 and accumulated depreciation of $45,061,000. At December 31, 2020, the Company held equipment under operating lease contracts with customers with an original cost of $75,241,000 and accumulated depreciation of $45,416,000.

As of December 31, 2021 and 2020, the Company recognized a loss on the write down of impaired assets of $105,000 and $8,264,000, respectively. The impaired assets included six Gamma Knife units and related removal costs, and two deposits towards the purchase of proton beam systems and related capitalized interest. See further discussion under Note 2 - Long-lived asset impairment and Note 3 - Property and Equipment.

Revenue recognition - The Company recognizes revenues under ASC 842 Leases (“ASC 842”) and ASC 606 Revenue from Contracts with Customers (“ASC 606”).

Rental income from medical services – The Company recognizes revenues under ASC 842 when services have been rendered and collectability is reasonably assured, on either a fee per use or revenue sharing basis. The terms of the contracts do not contain any guaranteed minimum payments. The Company’s contracts are typically for a 10-year term and are classified as either fee per use or retail. Retail arrangements are further classified as either turn-key or revenue sharing. Revenues from fee per use contracts is determined by each hospital’s contracted rate. Revenues are recognized at the time the procedures are performed, based on each hospital’s contracted rate and the number of procedures performed. Under revenue sharing arrangements, the Company receives a contracted percentage of the reimbursement received by the hospital. The amount the Company expects to receive is recorded as revenue and estimated based on historical experience. Revenue estimates are reviewed periodically and adjusted as necessary. Under turn-key arrangements, the Company receives payment from the hospital in the amount of the hospital’s reimbursement from third party payors, and the Company is responsible for paying all the operating costs of the equipment. Operating costs are determined primarily based on historical treatment protocols and cost schedules with the hospital. The Company records an estimate of operating costs which are reviewed on a regular basis and adjusted as necessary to more accurately reflect the actual operating costs. For turn-key sites, the Company also shares a percentage of net operating profit. The Company records an estimate of net operating profit based on estimated revenues, less estimated operating costs. The operating costs and estimated net operating profit are recorded as other direct operating costs in the consolidated statement of operations. As of December 31, 2021 and 2020, the Company recognized revenues of approximately $14,719,000 and $16,204,000 under ASC 842, respectively.

Patient income – The Company has stand-alone facilities in Lima, Peru and Guayaquil, Ecuador, where a contract exists between the Company’s facilities and the individual patient treated at the facility. Under ASC 606, the Company acts as the principal in this transaction and provides, at a point in time, a single performance obligation, in the form of a Gamma Knife treatment. Revenue related to a Gamma Knife treatment is recognized on a gross basis at the time when the patient receives treatment. There is no variable consideration present in the Company’s performance obligation and the transaction price is agreed upon per the stated contractual rate. GKPeru's payment terms are typically prepaid for self-pay patients and insurance provider payments are paid net 30 days. GKCE's patient population is primarily covered by a government payor and payments are paid approximately 30 to 60 days upon invoice. The Company did not capitalize any incremental costs related to the fulfillment of its customer contracts. Accounts receivable earned by GKPeru were not significant for the year ended December 31, 2021 and 2020. GKCE's accounts receivable were $435,000 and $467,000 for the years ended December 31, 2021 and 2020. As of December 31, 2021 and 2020, the Company recognized revenues of approximately $2,909,000 and $1,633,000 under ASC 606, respectively.

Stock-based compensation – The Company measures all stock-based compensation awards at fair value and records such expense in its consolidated financial statements over the requisite service period of the related award. See Note 10 - Stock-Based Compensation Expense for additional information on the Company’s stock-based compensation programs.

Costs of revenue – The Company's costs of revenue consist primarily of maintenance and supplies, depreciation and amortization, and other operating expenses (such as insurance, property taxes, sales taxes, marketing costs and operating costs from the Company’s retail sites). Costs of revenues are recognized as incurred.

Sales and Marketing – The Company markets its services through its preferred provider status with Elekta and a direct sales effort led by its Senior Vice President of Sales and Business Development, its President and Chief Financial and Operating Officer and its Chief Executive Officer (“CEO”).

The Company typically provides the equipment, as well as planning, installation, reimbursement and marketing support services.

Income taxes – The Company accounts for income taxes using the asset and liability method. Under this method, deferred tax assets and liabilities are determined based on differences between the financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse.

The Company accounts for uncertainty in income taxes as required by the provisions of ASC 740 Income taxes (“ASC 740”), which clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to estimate and measure the tax benefit as the largest amount that is more than 50% likely of being realized upon ultimate settlement. It is inherently difficult and subjective to estimate such amounts, as this requires the Company to determine the probability of various possible outcomes. The Company considers many factors when evaluating and estimating the Company’s tax positions and tax benefits, which may require periodic adjustments and may not accurately anticipate actual outcomes.

See Note 9 - Income Taxes for further discussion on income taxes.

Functional currency – Based on guidance provided in accordance with ASC 830, Foreign Currency Matters (“ASC 830”), the Company analyzes its operations outside the United States to determine the functional currency of each operation. Management has determined that these operations are initially accounted for in U.S. dollars since the primary transactions incurred are in U.S. dollars and the Company provides significant funding towards the startup of the operation. When Management determines that an operation has become predominantly self-sufficient, the Company will change its accounting for the operation to the local currency from the U.S. dollar. The Company analyzed it’s Gamma Knife site in Peru under ASC 830 as of December 31, 2021 and 2020 and concluded the functional currency was the U.S. dollar. As facts and circumstances change, the Company will revisit this conclusion.  The functional currency of the Company’s Gamma Knife site in Ecuador is the U.S. dollar because that is the local currency of Ecuador. 

Asset Retirement Obligations – Based on the guidance provided in ASC 410 Asset Retirement Obligations (“ASC 410”), the Company analyzed its existing lease agreements and determined an asset retirement obligation (“ARO”) exists to remove the respective units at the end of the lease terms. As of December 31, 2020, four of the Company's Gamma Knife customers notified the Company of their intent to terminate their contracts at the contract lease term. The Company recorded an ARO liability for these four sites, using estimates from Elekta. The Company increased its estimate for one of the AROs as of  December 31, 2021 by $105,000. No liability has been recorded as of December 31, 2021 for the remaining Gamma Knife sites, or as of December 31, 2020, because it is uncertain these units will be removed and the Company historically has not removed the Gamma Knife equipment at the end of the lease term. The Company will re-evaluate the need to record additional ARO liabilities on a periodic basis when facts and circumstances change that could affect this conclusion.

Earnings per share – Basic earnings per share excludes dilution and is computed by dividing income available to common shareholders by the weighted average number of common shares outstanding for the year. The fully vested restricted stock units not issued and outstanding, are also included therein. Diluted earnings per share reflect the potential dilution that could occur if common shares were issued pursuant to the exercise of options or warrants.

Because the Company reported a loss for the year ended December 31, 2020, the potentially dilutive effects of approximately 13,000, of the Company's unvested restricted stock awards were not considered for the reporting periods.

The following table illustrates the computations of basic and diluted earnings per share for the years ended December 31, 2021 and 2020.

	2021		2020
Numerator for basic and diluted earnings (loss) per share	$	194,000	$	(7,058,000	)
Denominator:
Denominator for basic and diluted earnings per share – weighted-average shares		6,044,000		6,182,000
Effect of dilutive securities Employee stock options and restricted stock		15,000		-
Denominator for diluted earnings per share – adjusted weighted-average shares		6,059,000		6,182,000
Earnings (loss) per common share- basic	$	0.03	$	(1.14	)
Earnings (loss) per common share- diluted	$	0.03	$	(1.14	)

In 2020, options outstanding to purchase 406,000 shares of common stock at an exercise price range of $2.25 - $3.90 per share and 13,000 restricted stock units were not included in the calculation of diluted earnings per share because they would be anti-dilutive.

Business segment information - Based on the guidance provided in accordance with ASC 280 Segment Reporting (“ASC 280”), the Company analyzed its subsidiaries which are all in the business of leasing radiosurgery and radiation therapy equipment to healthcare providers, and concluded there are two reportable segments, domestic and foreign. The Company provides Gamma Knife and PBRT equipment to fourteen hospitals in the United States and owns and operates two single-unit facilities in Lima, Peru and Guayaquil, Ecuador as of December 31, 2021. The Company determined two reportable segments existed due to similarities in economics of business operations and geographic location. The operating results of the two reportable segments are reviewed by the Company’s CEO and President, Chief Operating and Financial Officer, who are also deemed the Company’s Chief Operating Decision Makers (“CODMs”). 

The revenues, profit or loss, and net property and equipment allocations for the Company's two reportable segments as of December 31, 2021 and 2020 consists of the following:

	2021		2020
Revenues
Domestic	$	14,719,000	$	16,204,000
Foreign		2,909,000		1,633,000
Total	$	17,628,000	$	17,837,000

	2021			2020
Profit or (loss)
Domestic	$	245,000		$	(7,082,000	)
Foreign		(51,000	)		24,000
Total	$	194,000		$	(7,058,000	)

	2021		2020
Property and equipment, net
Domestic	$	25,557,000	$	27,223,000
Foreign		2,697,000		3,195,000
Total	$	28,254,000	$	30,418,000

Long lived asset impairment – The Company assesses the recoverability of its long-lived assets when events or changes in circumstances indicate their carrying value may not be recoverable. Such events or changes in circumstances may include: a significant adverse change in the extent or manner in which a long-lived asset is being used, significant adverse change in legal factors or in the business climate that could affect the value of a long-lived asset, an accumulation of costs significantly in excess of the amount originally expected for the acquisition or development of a long-lived asset, current or future operating or cash flow losses that demonstrate continuing losses associated with the use of a long-lived asset, or a current expectation that, more likely than not, a long-lived asset will be sold or otherwise disposed of significantly before the end of its previously estimated useful life. The Company performs impairment testing at the asset group level that represents the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. The Company assesses recoverability of a long-lived asset by determining whether the carrying value of the asset group can be recovered through projected undiscounted cash flows over their remaining lives. If the carrying value of the asset group exceeds the forecasted undiscounted cash flows, an impairment loss is recognized, measured as the amount by which the carrying amount exceeds estimated fair value. An impairment loss is charged to the consolidated statement of operations in the period in which management determines such impairment. As of December 31, 2020, the Company determined circumstances existed indicating its assets could be impaired, concluded an impairment existed, and recognized a loss on the write down of impaired assets of $8,264,000. As of December 31, 2021, an additional impairment of $105,000 related to the removal costs of one of the Gamma Knife units that was impaired at December 31, 2020 was recorded.  No other additional impairment has been noted as of December 31, 2021. See Note 3 - Property and Equipment for further discussion.

Goodwill and intangible assets - The Company recorded goodwill of $1,265,000 and an intangible asset with a fair value of $78,000 as part of the Acquisition in June 2020. The intangible asset identified was GKCE's trade name and the Company assigned an indefinite useful life to the asset. Based on the guidance provided in accordance with ASC 350 Intangibles-Goodwill and Other (“ASC 350”), the Company does not amortize the intangible asset because it has an indefinite life. The Company assesses goodwill at the reporting unit level, which has been determined to be GKCE. Each reporting period, the Company assesses whether events or circumstances continue to support an indefinite useful life for the intangible asset. Per ASC 350, the Company tests goodwill and intangibles for impairment annually or as events or circumstances change that indicate the fair value may be below the carrying amount. As of December 31, 2021 and 2020, there has been no change to the Company's assessment of the value of intangible assets or goodwill.

Acquisitions - The Company records acquisitions according to ASC 805 Business Combinations (“ASC 805”) using the acquisition method of accounting. Under the acquisition method of accounting, all assets acquired, including goodwill and other intangible assets, should be stated at fair value at the time of acquisition. See Note 5 - GKCE Acquisition for further discussion on acquisitions.

Accounting pronouncements issued and not yet adopted - In January 2021, the FASB issued ASU 2021-01 Reference Rate Reform (Topic 848) (“ASU 2021-01”) which provides optional expedients and exceptions for applying generally accepted accounting principles to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendments in ASU 2021-01 apply only to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. ASU 2021-01 is effective any date from the beginning of an interim period that includes or is subsequent to March 12, 2020, or on a prospective basis to new modifications. The Company is currently evaluating ASU 2021-01 to determine the impact it may have on its consolidated financial statements. See Note 6 - Long-term debt for additional disussion on transition from LIBOR. 

Reclassifications – Certain comparative balances as of and for the year ended December 31, 2020 have been reclassified to make them consistent with the current year presentation.
