Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Significant Policies	Basis of Presentation and Significant Policies Basis of Presentation The unaudited condensed consolidated financial statements included in this Form 10-Q have been prepared in accordance with the U.S. Securities and Exchange Commission (the “SEC”) instructions for Quarterly Reports on Form 10-Q. Accordingly, the condensed consolidated financial statements are unaudited and do not contain all the information required by U.S. generally accepted accounting principles (“GAAP”) to be included in a full set of financial statements. The unaudited condensed consolidated balance sheet at December 31, 2021 has been derived from the audited consolidated financial statements at that date but does not include all of the information and footnotes required by GAAP for a complete set of financial statements. The audited consolidated financial statements for our fiscal year ended December 31, 2021, filed with the SEC on Form 10-K on March 31, 2022, include a summary of our significant accounting policies and should be read in conjunction with this Form 10-Q. In the opinion of management, all material adjustments necessary to present fairly the results of operations, cash flows, and balance sheets for such periods have been included in this Form 10-Q. All such adjustments are of a normal recurring nature. The results of operations for interim periods are not necessarily indicative of the results of operations for the entire year. The Company and Discontinued Operations On March 31, 2021, Star Equity Holdings, Inc. (“Star Equity,” the “Company,” “we,” or “our”), a diversified holding company with three divisions: Healthcare, Construction, and Investments, announced the completion of the sale of DMS Health Technologies, Inc., a North Dakota corporation and wholly owned indirect subsidiary of Star Equity (“DMS Health”), for $18.75 million in cash, as originally announced on November 3, 2020 (the “DMS Sale Transaction”). The assets and liabilities of DMS Health were previously classified as held for sale and the results of DMS Health’s operations were presented as a discontinued operations in our previously issued financial statements. Unless otherwise noted, discussion within these notes to the condensed consolidated financial statements relates to continuing operations. Refer to Note 2. Discontinued Operations for additional information. Mezzanine Equity Pursuant to the Certificate of Designations, Rights and Preferences of 10% Series A Cumulative Perpetual Preferred Stock (the “Series A Preferred Stock”) of Star Equity (formerly Digirad Corporation) (the “Certificate of Designations”), upon a Change of Control Triggering Event, as defined in the Certificate of Designations, holders of the Series A Preferred Stock may require the Company to redeem the Series A Preferred Stock at a price of $10.00 per share, plus any accumulated and unpaid dividends (a “Change of Control Redemption”). As this redemption feature of the shares is not solely within the control of the Company, the Series A Preferred Stock does not qualify as permanent equity and has been classified as mezzanine or temporary equity. Series A Preferred Stock is not redeemable and it was not probable that our Series A Preferred Stock would become redeemable as of March 31, 2022 and 2021. Therefore, we are not currently required to accrete the Series A Preferred Stock to its redemption value. In addition to a Change of Control Redemption, the Certificate of Designations also provides that we may redeem (at our option, in whole or in part) the Series A Preferred Stock following the fifth anniversary of issuance of the Series A Preferred Stock, at a cash redemption price of $10.00 per share, plus any accumulated and unpaid dividends. On February 25, 2022, our board of directors declared a cash dividend to holders of our Series A Preferred Stock of $0.25 per share, for an aggregate amount of approximately $0.5 million. The record date for this dividend was March 1, 2022, and the payment date was March 10, 2022. Refer to preferred stock dividends discussed in Note 13. Perpetual Preferred Stock. Going Concern The accompanying condensed consolidated financial statements have been prepared assuming we will continue as a going concern, which contemplates the realization of assets and settlement of obligations in the normal course of business. We incurred losses from continuing operations, net of income taxes, of approximately $3.7 million and $0.6 million for the three months ended March 31, 2022 and 2021, respectively. We have an accumulated deficit of $131.7 million and $128.0 million as of March 31, 2022 and December 31, 2021, respectively. Net cash used in operations was $0.6 million for the three months ended March 31, 2022, compared to net cash used in operations of $2.2 million for the same period in 2021. We will likely need to secure additional financing in the future to accomplish our business plan over the next several years and there can be no assurance on the availability or terms upon which such financing and capital might be available at that time. As of March 31, 2022, cash and cash equivalents increased to $15.0 million from $4.5 million as of December 31, 2021. At March 31, 2022, we had approximately $13.3 million in debt outstanding. All of our debt is categorized as short-term on our condensed Consolidated Balance Sheets. For more detail, see Note 8. Debt. The Company’s loan pursuant to the SNB Loan Agreement (as defined below) (the “SNB Loan”) with Sterling National Bank, a national banking association as lender (“Sterling” or “SNB”), which has a current balance owed of $7.3 million, supports our Healthcare business. On February 1, 2022, Sterling became part of Webster Bank, N.A. (“Webster”), and Webster became successor in interest to the SNB Loan Agreement. While the SNB Loan matures in 2024, GAAP rules require that the outstanding balance be classified as short-term debt. This is due to both the automatic sweep feature embedded in the traditional lockbox arrangement and the subjective acceleration clause in the SNB Loan Agreement. As of March 31, 2022, we were not in compliance with covenants in the SNB Loan Agreement related to our Healthcare division and we have not yet obtained a waiver from Webster for these financial covenant breaches. We are currently in negotiations to avoid a default. While we do not believe we will be required to pay down the current balance, our current cash is sufficient to repay the SNB Loan in full. Upon the occurrence and during the continuation of an event of default under the SNB Loan Agreement, Webster may, among other things, declare the loans and all other obligations under the SNB Loan Agreement immediately due and payable and increase the interest rate at which loans and obligations under the SNB Loan Agreement bear interest. Management has concluded that this forecasted violation raises substantial doubt about our ability to continue as a going concern within twelve months after the date that financial statements are issued, if we are not able to restructure those agreements or receive a waiver for non-compliance with our covenants. Our financial statements do not reflect any adjustments that might result from the outcome of this uncertainty. Management is taking a number of steps to avoid these breaches and/or restructure the covenants within these agreements. These steps include improving our operations, considering additional or alternative financing arrangements, and negotiating with current lenders to amend our covenants. While we believe that we maintain strong transparency and relationships with our lenders, there can be no assurance that we will be successful in these efforts. As of March 31, 2022, we had $5.0 million outstanding on our two Construction division revolvers with Gerber Finance, Inc. (“Gerber”). As of December 31, 2021, we were not in compliance with our bi-annual covenants on either of these Gerber facilities. However, we have obtained waivers from Gerber covering the measurement period ending June 30, 2022. While Gerber has historically provided us with such waivers, when needed, there is no assurance that we will be able to receive waivers for covenant violations in the future. On January 31, 2020, we and certain of our Investments subsidiaries entered into a Loan and Security Agreement with Gerber (as amended, the “Star Loan Agreement”), which provides for a credit facility with borrowing availability of up to $2.5 million, bearing interest at the prime rate plus 3.5% per annum, and matures on January 1, 2025, unless terminated in accordance with the terms therein (the “Star Loan”). We currently have $1.0 million outstanding on the Star Loan, on which we are and historically have been making timely payments in full compliance with all covenants. Related party notes of $2.3 million that were outstanding as of December 31, 2020 were fully paid off on April 1, 2021 using proceeds from the DMS Sale Transaction. On January 24, 2022, we closed an underwritten public offering (the “2022 Public Offering”), and gross proceeds, before deducting underwriting discounts and offering expenses and excluding any proceeds we may receive upon exercise of the common warrants, were $14.3 million and net proceeds were $12.7 million. Refer to Note 14. Equity Transactions for details. In the first quarter of 2022, we declared and made $0.5 million preferred stock dividend payment. In the second quarter of 2022, we declared a $0.5 million preferred stock dividend payment. Refer to Note 13. Perpetual Preferred Stock and Note 17. Subsequent Events for details. Use of Estimates The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and disclosures made in the accompanying notes to the condensed consolidated financial statements. Significant estimates and judgments include those related to revenue recognition, goodwill valuation, and income taxes. Actual results could materially differ from those estimates. Revenue Recognition We recognize revenue in accordance with Accounting Standards Codification (“ASC”) Topic 606 and Topic 842. Pursuant to ASC 606, Revenue from Contracts with Customers, we recognize revenue when a customer obtains control of promised goods or services. We record the amount of revenue that reflects the consideration that it expects to receive in exchange for those goods or services. We apply the following five-step model in order to determine this amount: (i) identification of the promised goods or services in the contract; (ii) determination of whether the promised goods or services are performance obligations, including whether they are distinct in the context of the contract; (iii) measurement of the transaction price, including the constraint on variable consideration; (iv) allocation of the transaction price to the performance obligations; and (v) recognition of revenue when (or as) the Company satisfies each performance obligation. The Company has elected to use the practical expedient under ASC 606 to exclude disclosures of unsatisfied remaining performance obligations for (i) contracts having an original expected length of one year or less or (ii) contracts for which the practical expedient has been applied to recognize revenue at the amount for which it has a right to invoice. Revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration we expect to receive in exchange for those products or services. Taxes collected from customers, which are subsequently remitted to governmental authorities, are excluded from revenue. The majority of our contracts have a single performance obligation, as we provide a series of distinct goods or services that are substantially the same and are transferred with the same pattern to the customer. For contracts with multiple performance obligations, we allocate the total transaction price to each performance obligation using our best estimate of the standalone selling price of each distinct good or service in the contract. We use an observable price to determine the stand-alone selling price for separate performance obligations or a cost plus margin approach when one is not available. For bill and hold sales, we determine when the customer obtains control of the product on a case-by-case basis to determine the amount of revenue to recognize each period. Revenue recognition is evaluated on a contract by contract basis. Performance obligations are satisfied over time as work progresses or at a point in time. A performance obligation is satisfied over time if we have an enforceable right to payment. Determining if there is an enforceable right to payment is assessed on a contract by contract basis. For contracts requiring over time revenue recognition, the selection of the method to measure progress towards completion requires judgment and is based on the nature of the products or services to be provided. We use a cost-based input measurement of progress because it best depicts the transfer of assets to the customer, which occurs as costs are incurred during the manufacturing process or as services are rendered. Under the cost-based measure of progress, the extent of progress towards completion is measured based on the costs incurred to date. Our products are generally not sold with a right of return and the Company does not provide significant credits or incentives, which may be variable consideration when estimating the amount of revenue to be recognized. Healthcare Services Revenue Recognition. We generate service revenue primarily from providing diagnostic services to our customers. Service revenue within our Healthcare reportable segment is derived from providing our customers with contract diagnostic services, which includes use of our imaging systems, qualified personnel, radiopharmaceuticals, licensing, logistics and related items required to perform testing in their own offices. We bill customers either on a per-scan or fixed-payment methodology, depending upon the contract that is negotiated with the customer. Within our Healthcare segment, we also rent cameras to healthcare customers for use in their operations. Rental revenues are structured as either a weekly or monthly payment arrangement, and are recognized in the month rental assets are provided. Revenue related to provision of our services is recognized at the time services are performed. Healthcare Product and Product-Related Revenue Recognition. We generate revenue from product and product-related sales, primarily from the sale of gamma cameras, accessories, and radiopharmaceuticals doses. Healthcare product revenues are generated from the sale of internally developed solid-state gamma camera imaging systems and post-warranty camera maintenance service contracts. Revenue from sales of imaging systems is generally recognized at point in time upon delivery of systems and acceptance by customers. We also provide installation services and training on cameras sold, primarily in the United States. Installation and initial training is generally performed shortly after delivery and the revenue related to the provision of these services is recognized at the time services are performed. Neither installation nor training is essential to the functionality of the product. Finally, we offer camera maintenance service contracts that are sold beyond the term of the initial warranty, generally one year from the date of purchase. Revenue from these service contracts is deferred and recognized ratably over the period of the obligation. We offer time and material services and record revenue when service is performed. Radiopharmaceuticals doses revenue, generated by Healthcare, is generally recognized when delivered to the customer. Construction Revenue Recognition. Within the Construction division, we service residential and commercial construction projects by manufacturing modular housing units and other products and supply general contractors with building materials. KBS manufactures modular buildings for both single-family residential homes and larger, commercial building projects. EdgeBuilder manufactures structural wall panels, permanent wood foundation systems and other engineered wood products, and Glenbrook is a retail supplier of lumber and other building supplies. Retail sales at Glenbrook are recognized at the point of sale. For bill and hold sales, we determine when the customer obtains control of the product on a case-by-case basis to determine the amount of revenue to recognize each period. Revenue is generally recognized at point in time upon delivery of product or over time by measuring progress towards completion Billings in excess of costs and estimated earnings. We recognize billings in excess of costs and estimated earnings on uncompleted contracts are current liabilities, which relate to fixed-price contracts recognized over time, and represents payments in advance of performing the related contract work. Billings in excess of costs and estimated earnings on uncompleted contracts are not considered to be a significant financing component because they are generally used to meet working capital demands that can be higher in the early stages of a contract. Contract liabilities are classified in deferred revenue in the condensed Consolidated Balance Sheets. Contract liabilities are reduced when the associated revenue from the contract is recognized, which is generally within one year. Contract Costs. We recognize an asset for the incremental costs of obtaining a contract with a customer if we expect the benefit of those costs to be longer than one year. The Company applies a practical expedient to expense costs as incurred for costs to obtain a contract when the amortization period would have been one year or less. These costs mainly include the internal sales commissions; under the terms of these programs these are generally earned and the costs are recognized at the time the revenue is recognized. Deferred Revenue We record deferred revenue when cash payments are received in advance of our performance. We have determined our contracts do not include a significant financing component. The majority of our deferred revenue relates to payments received on camera support post-warranty service contracts, which are billed at the beginning of the contract period or at periodic intervals (e.g., monthly, quarterly, or annually). Leases Lessee Accounting We determine if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (“ROU”) assets, operating lease liabilities, and operating lease liabilities, net of current portion in our condensed consolidated balance sheets. Finance leases are included in property and equipment, other current liabilities, and other long-term liabilities in our condensed Consolidated Balance Sheets. ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. We use the implicit discount rate when readily determinable; however, as most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The operating lease ROU asset also includes any lease payments made and excludes lease incentives. Our lease valuation may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. We elected not to separate lease and non-lease components of its operating leases in which it is the lessee and lessor. Additionally, we elected not to recognize right-of-use assets and leases liabilities that arise from short-term leases of twelve months or less. Lessor Accounting The majority of the lease income of the Healthcare division comes from camera rentals and the lease income of the Construction division comes from the rental of the Waterford facility to a commercial tenant. We determine lease classification at the commencement date. Leases not classified as sales-type or direct financing leases are classified as operating leases. The primary accounting criteria we use for lease classification are (a) review to determine if the lease transfers ownership of the underlying asset to the lessee by the end of the lease term, (b) review to determine if the lease grants the lessee a purchase option that the lessee is reasonably certain to exercise, (c) determine, using a seventy-five percent or more threshold, if the lease term is for a major part of the remaining economic life of the underlying asset (however, we do not use this classification criterion when the lease commencement date falls within the last 25 percent of the total economic life of the underlying asset) and (d) determine, using a 90 percent or more threshold, if the present value of the sum of the lease payments and any residual value guarantees equal or exceeds substantially all of the fair value of the underlying asset. We do not lease equipment of such a specialized nature that it is expected to have no alternative use to the lessor at the end of the lease term. Each of our leases is classified as an operating lease. We elected the operating lease practical expedient for its leases to not separate non-lease components of regular maintenance services from associated lease components. This practical expedient is available when both of the following are met: (i) the timing and pattern of transfer of the non-lease components and associated lease component are the same and (ii) the lease component, if accounted for separately, would be classified as an operating lease. Property taxes paid by the lessor that are reimbursed by the lessee are considered to be lessor costs of owning the asset, and are recorded gross with revenue included in other non-interest income and expense recorded in operating expenses. We selected a lessor accounting policy election to exclude from revenue and expenses sales taxes and other similar taxes assessed by a governmental authority on lease revenue-producing transactions and collected by the lessor from a lessee. Operating lease equipment is carried at cost less accumulated depreciation. Operating lease equipment is depreciated to its estimated residual value using the straight-line method over the lease term or estimated useful life of the asset. Rental revenue on operating leases is recognized on a straight-line basis over the lease term unless collectability is not probable. In these cases, rental revenue is recognized as payments are received. Concentration of Credit Risk Financial instruments, which potentially subject us to concentrations of credit risk, consist primarily of cash and cash equivalents and accounts receivable. We limit our exposure to credit loss by generally placing cash in high credit quality financial institutions. Cash balances are maintained primarily at major financial institutions in the United States and a portion of which exceed the regulatory limit of $250,000 insured by the Federal Deposit Insurance Corporation (FDIC). We have not experienced any credit losses associated with our cash balances. Additionally, we have established guidelines regarding diversification of our investments and their maturities, which are designed to maintain principal and maximize liquidity. Variable Interest Entities We determine at the inception of each arrangement whether an entity in which we have made an investment or in which we have other variable interests is considered a variable interest entity (“VIE”). We consolidate VIEs when we are the primary beneficiary. We are the primary beneficiary of a VIE when we have the power to direct activities that most significantly affect the economic performance of the VIE and have the obligation to absorb the significant losses or benefits. If we are not the primary beneficiary in a VIE, we account for the investment or other variable interests in a VIE in accordance with applicable GAAP. Periodically, we assess whether any changes in our interest or relationship with the entity affect our determination of whether the entity is a VIE and, if so, whether we are the primary beneficiary. Reclassification PPP Loan forgiveness reclassification has been made to the prior period financial statements to conform to the current year financial statement presentation of the condensed Consolidated Statements of Operations. This change did not impact previously reported net loss, loss per share, stockholders’ equity, total assets or the condensed Consolidated Statements of Cash Flows. Finance Lease liabilities and Investments reclassifications have been made to the prior period financial statements to conform to the current year financial statement presentation of the condensed Consolidated Balance Sheets. These changes did not impact previously reported net (loss) income, (loss) income per share, stockholders’ equity, total liabilities, total assets or the condensed Consolidated Statements of Cash Flows. New Accounting Standards To Be Adopted In June 2016, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2016-13, Financial Instruments - Credit Losses: Measurement of Credit Losses on Financial Instruments, which amends the impairment model by requiring entities to use a forward-looking approach based on expected losses to estimate credit losses on certain types of financial instruments, including trade receivables and available-for-sale debt securities. This update is effective for annual periods beginning after December 15, 2022, and interim periods within those periods, and early adoption is permitted. We expect to adopt the standard on its effective date in the first quarter of 2023. We believe the adoption will modify the way we analyze financial instruments, but currently do not expect the adoption to have a material financial impact on our condensed consolidated financial statements. In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848), to temporarily ease the potential burden in accounting for reference rate reform. The standard provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships and other transactions affected by reference rate reform. The guidance generally can be applied through December 31, 2022. We will monitor our contracts and transactions for potential application of this ASU. Recently Adopted Accounting Standards In August 2020, the FASB issued ASU No. 2020-06, Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40). ASU 2020-06 eliminates the beneficial conversion and cash conversion accounting models for convertible instruments. It also amends the accounting for certain contracts in an entity’s own equity that are currently accounted for as derivatives because of specific settlement provisions. In addition, ASU 2020-06 modifies how particular convertible instruments and certain contracts that may be settled in cash or shares impact the diluted EPS computation. The amendments in this update are effective for public business entities for fiscal years beginning after December 15, 2021 (or December 15, 2023 for companies who meet the SEC definition of Smaller Reporting Companies), and interim periods within those fiscal years. The amendment is to be adopted through either a fully retrospective or modified retrospective method of transition. Early adoption is permitted. The Company early adopted this standard on January 1, 2021 by applying the modified retrospective approach. There was no cumulative-effect transition adjustment required to the opening balance of accumulated deficit upon the adoption of this standard.

The unaudited condensed consolidated financial statements included in this Form 10-Q have been prepared in accordance with the U.S. Securities and Exchange Commission (the “SEC”) instructions for Quarterly Reports on Form 10-Q. Accordingly, the condensed consolidated financial statements are unaudited and do not contain all the information required by U.S. generally accepted accounting principles (“GAAP”) to be included in a full set of financial statements. The unaudited condensed consolidated balance sheet at December 31, 2021 has been derived from the audited consolidated financial statements at that date but does not include all of the information and footnotes required by GAAP for a complete set of financial statements. The audited consolidated financial statements for our fiscal year ended December 31, 2021, filed with the SEC on Form 10-K on March 31, 2022, include a summary of our significant accounting policies and should be read in conjunction with this Form 10-Q. In the opinion of management, all material adjustments necessary to present fairly the results of operations, cash flows, and balance sheets for such periods have been included in this Form 10-Q. All such adjustments are of a normal recurring nature. The results of operations for interim periods are not necessarily indicative of the results of operations for the entire year.

On March 31, 2021, Star Equity Holdings, Inc. (“Star Equity,” the “Company,” “we,” or “our”), a diversified holding company with three divisions: Healthcare, Construction, and Investments, announced the completion of the sale of DMS Health Technologies, Inc., a North Dakota corporation and wholly owned indirect subsidiary of Star Equity (“DMS Health”), for $18.75 million in cash, as originally announced on November 3, 2020 (the “DMS Sale Transaction”). The assets and liabilities of DMS Health were previously classified as held for sale and the results of DMS Health’s operations were presented as a discontinued operations in our previously issued financial statements. Unless otherwise noted, discussion within these notes to the condensed consolidated financial statements relates to continuing operations. Refer to Note 2. Discontinued Operations for additional information.

Pursuant to the Certificate of Designations, Rights and Preferences of 10% Series A Cumulative Perpetual Preferred Stock (the “Series A Preferred Stock”) of Star Equity (formerly Digirad Corporation) (the “Certificate of Designations”), upon a Change of Control Triggering Event, as defined in the Certificate of Designations, holders of the Series A Preferred Stock may require the Company to redeem the Series A Preferred Stock at a price of $10.00 per share, plus any accumulated and unpaid dividends (a “Change of Control Redemption”). As this redemption feature of the shares is not solely within the control of the Company, the Series A Preferred Stock does not qualify as permanent equity and has been classified as mezzanine or temporary equity. Series A Preferred Stock is not redeemable and it was not probable that our Series A Preferred Stock would become redeemable as of March 31, 2022 and 2021. Therefore, we are not currently required to accrete the Series A Preferred Stock to its redemption value.

In addition to a Change of Control Redemption, the Certificate of Designations also provides that we may redeem (at our option, in whole or in part) the Series A Preferred Stock following the fifth anniversary of issuance of the Series A Preferred Stock, at a cash redemption price of $10.00 per share, plus any accumulated and unpaid dividends.

On February 25, 2022, our board of directors declared a cash dividend to holders of our Series A Preferred Stock of $0.25 per share, for an aggregate amount of approximately $0.5 million. The record date for this dividend was March 1, 2022, and the payment date was March 10, 2022. Refer to preferred stock dividends discussed in Note 13. Perpetual Preferred Stock.

The accompanying condensed consolidated financial statements have been prepared assuming we will continue as a going concern, which contemplates the realization of assets and settlement of obligations in the normal course of business. We incurred losses from continuing operations, net of income taxes, of approximately $3.7 million and $0.6 million for the three months ended March 31, 2022 and 2021, respectively. We have an accumulated deficit of $131.7 million and $128.0 million as of March 31, 2022 and December 31, 2021, respectively. Net cash used in operations was $0.6 million for the three months ended March 31, 2022, compared to net cash used in operations of $2.2 million for the same period in 2021. We will likely need to secure additional financing in the future to accomplish our business plan over the next several years and there can be no assurance on the availability or terms upon which such financing and capital might be available at that time. As of March 31, 2022, cash and cash equivalents increased to $15.0 million from $4.5 million as of December 31, 2021.

At March 31, 2022, we had approximately $13.3 million in debt outstanding. All of our debt is categorized as short-term on our condensed Consolidated Balance Sheets. For more detail, see Note 8. Debt. The Company’s loan pursuant to the SNB Loan Agreement (as defined below) (the “SNB Loan”) with Sterling National Bank, a national banking association as lender (“Sterling” or “SNB”), which has a current balance owed of $7.3 million, supports our Healthcare business. On February 1, 2022, Sterling became part of Webster Bank, N.A. (“Webster”), and Webster became successor in interest to the SNB Loan Agreement. While the SNB Loan matures in 2024, GAAP rules require that the outstanding balance be classified as short-term debt. This is due to both the automatic sweep feature embedded in the traditional lockbox arrangement and the subjective acceleration clause in the SNB Loan Agreement. As of March 31, 2022, we were not in compliance with covenants in the SNB Loan Agreement related to our Healthcare division and we have not yet obtained a waiver from Webster for these financial covenant breaches. We are currently in negotiations to avoid a default. While we do not believe we will be required to pay down the current balance, our current cash is sufficient to repay the SNB Loan in full.

Upon the occurrence and during the continuation of an event of default under the SNB Loan Agreement, Webster may, among other things, declare the loans and all other obligations under the SNB Loan Agreement immediately due and payable and increase the interest rate at which loans and obligations under the SNB Loan Agreement bear interest. Management has concluded that this forecasted violation raises substantial doubt about our ability to continue as a going concern within twelve months after the date that financial statements are issued, if we are not able to restructure those agreements or receive a waiver for non-compliance with our covenants. Our financial statements do not reflect any adjustments that might result from the outcome of this uncertainty. Management is taking a number of steps to avoid these breaches and/or restructure the covenants within these agreements. These steps include improving our operations, considering additional or alternative financing arrangements, and negotiating with current lenders to amend our covenants. While we believe that we maintain strong transparency and relationships with our lenders, there can be no assurance that we will be successful in these efforts.

As of March 31, 2022, we had $5.0 million outstanding on our two Construction division revolvers with Gerber Finance, Inc. (“Gerber”). As of December 31, 2021, we were not in compliance with our bi-annual covenants on either of these Gerber facilities. However, we have obtained waivers from Gerber covering the measurement period ending June 30, 2022. While Gerber has historically provided us with such waivers, when needed, there is no assurance that we will be able to receive waivers for covenant violations in the future.

On January 31, 2020, we and certain of our Investments subsidiaries entered into a Loan and Security Agreement with Gerber (as amended, the “Star Loan Agreement”), which provides for a credit facility with borrowing availability of up to $2.5 million, bearing interest at the prime rate plus 3.5% per annum, and matures on January 1, 2025, unless terminated in accordance with the terms therein (the “Star Loan”). We currently have $1.0 million outstanding on the Star Loan, on which we are and historically have been making timely payments in full compliance with all covenants. Related party notes of $2.3 million that were outstanding as of December 31, 2020 were fully paid off on April 1, 2021 using proceeds from the DMS Sale Transaction.

On January 24, 2022, we closed an underwritten public offering (the “2022 Public Offering”), and gross proceeds, before deducting underwriting discounts and offering expenses and excluding any proceeds we may receive upon exercise of the common warrants, were $14.3 million and net proceeds were $12.7 million. Refer to Note 14. Equity Transactions for details.

The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and disclosures made in the accompanying notes to the condensed consolidated financial statements. Significant estimates and judgments include those related to revenue recognition, goodwill valuation, and income taxes. Actual results could materially differ from those estimates.

Pursuant to ASC 606, Revenue from Contracts with Customers, we recognize revenue when a customer obtains control of promised goods or services. We record the amount of revenue that reflects the consideration that it expects to receive in exchange for those goods or services. We apply the following five-step model in order to determine this amount: (i) identification of the promised goods or services in the contract; (ii) determination of whether the promised goods or services are performance obligations, including whether they are distinct in the context of the contract; (iii) measurement of the transaction price, including the constraint on variable consideration; (iv) allocation of the transaction price to the performance obligations; and (v) recognition of revenue when (or as) the Company satisfies each performance obligation.

The Company has elected to use the practical expedient under ASC 606 to exclude disclosures of unsatisfied remaining performance obligations for (i) contracts having an original expected length of one year or less or (ii) contracts for which the practical expedient has been applied to recognize revenue at the amount for which it has a right to invoice.

Revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration we expect to receive in exchange for those products or services. Taxes collected from customers, which are subsequently remitted to governmental authorities, are excluded from revenue.

The majority of our contracts have a single performance obligation, as we provide a series of distinct goods or services that are substantially the same and are transferred with the same pattern to the customer. For contracts with multiple performance obligations, we allocate the total transaction price to each performance obligation using our best estimate of the standalone selling price of each distinct good or service in the contract. We use an observable price to determine the stand-alone selling price for separate performance obligations or a cost plus margin approach when one is not available. For bill and hold sales, we determine when the customer obtains control of the product on a case-by-case basis to determine the amount of revenue to recognize each period.

Revenue recognition is evaluated on a contract by contract basis. Performance obligations are satisfied over time as work progresses or at a point in time. A performance obligation is satisfied over time if we have an enforceable right to payment. Determining if there is an enforceable right to payment is assessed on a contract by contract basis. For contracts requiring over time revenue recognition, the selection of the method to measure progress towards completion requires judgment and is based on the nature of the products or services to be provided. We use a cost-based input measurement of progress because it best depicts the transfer of assets to the customer, which occurs as costs are incurred during the manufacturing process or as services are rendered. Under the cost-based measure of progress, the extent of progress towards completion is measured based on the costs incurred to date.

Healthcare Services Revenue Recognition. We generate service revenue primarily from providing diagnostic services to our customers. Service revenue within our Healthcare reportable segment is derived from providing our customers with contract diagnostic services, which includes use of our imaging systems, qualified personnel, radiopharmaceuticals, licensing, logistics and related items required to perform testing in their own offices. We bill customers either on a per-scan or fixed-payment methodology, depending upon the contract that is negotiated with the customer. Within our Healthcare segment, we also rent cameras to healthcare customers for use in their operations. Rental revenues are structured as either a weekly or monthly payment arrangement, and are recognized in the month rental assets are provided. Revenue related to provision of our services is recognized at the time services are performed.

Healthcare product revenues are generated from the sale of internally developed solid-state gamma camera imaging systems and post-warranty camera maintenance service contracts. Revenue from sales of imaging systems is generally recognized at point in time upon delivery of systems and acceptance by customers. We also provide installation services and training on cameras sold, primarily in the United States. Installation and initial training is generally performed shortly after delivery and the revenue related to the provision of these services is recognized at the time services are performed. Neither installation nor training is essential to the functionality of the product. Finally, we offer camera maintenance service contracts that are sold beyond the term of the initial warranty, generally one year from the date of purchase. Revenue from these service contracts is deferred and recognized ratably over the period of the obligation. We offer time and material services and record revenue when service is performed. Radiopharmaceuticals doses revenue, generated by Healthcare, is generally recognized when delivered to the customer.

Construction Revenue Recognition. Within the Construction division, we service residential and commercial construction projects by manufacturing modular housing units and other products and supply general contractors with building materials. KBS manufactures modular buildings for both single-family residential homes and larger, commercial building projects. EdgeBuilder manufactures structural wall panels, permanent wood foundation systems and other engineered wood products, and Glenbrook is a retail supplier of lumber and other building supplies. Retail sales at Glenbrook are recognized at the point of sale. For bill and hold sales, we determine when the customer obtains control of the product on a case-by-case basis to determine the amount of revenue to recognize each period. Revenue is generally recognized at point in time upon delivery of product or over time by measuring progress towards completion

Billings in excess of costs and estimated earnings. We recognize billings in excess of costs and estimated earnings on uncompleted contracts are current liabilities, which relate to fixed-price contracts recognized over time, and represents payments in advance of performing the related contract work. Billings in excess of costs and estimated earnings on uncompleted contracts are not considered to be a significant financing component because they are generally used to meet working capital demands that can be higher in the early stages of a contract. Contract liabilities are classified in deferred revenue in the condensed Consolidated Balance Sheets. Contract liabilities are reduced when the associated revenue from the contract is recognized, which is generally within one year.

Contract Costs. We recognize an asset for the incremental costs of obtaining a contract with a customer if we expect the benefit of those costs to be longer than one year. The Company applies a practical expedient to expense costs as incurred for costs to obtain a contract when the amortization period would have been one year or less. These costs mainly include the internal sales commissions; under the terms of these programs these are generally earned and the costs are recognized at the time the revenue is recognized.

We record deferred revenue when cash payments are received in advance of our performance. We have determined our contracts do not include a significant financing component. The majority of our deferred revenue relates to payments received on camera support post-warranty service contracts, which are billed at the beginning of the contract period or at periodic intervals (e.g., monthly, quarterly, or annually).

We determine if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (“ROU”) assets, operating lease liabilities, and operating lease liabilities, net of current portion in our condensed consolidated balance sheets. Finance leases are included in property and equipment, other current liabilities, and other long-term liabilities in our condensed Consolidated Balance Sheets.

ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. We use the implicit discount rate when readily determinable; however, as most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The operating lease ROU asset also includes any lease payments made and excludes lease incentives. Our lease valuation may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term.

The majority of the lease income of the Healthcare division comes from camera rentals and the lease income of the Construction division comes from the rental of the Waterford facility to a commercial tenant. We determine lease classification at the commencement date. Leases not classified as sales-type or direct financing leases are classified as operating leases. The primary accounting criteria we use for lease classification are (a) review to determine if the lease transfers ownership of the underlying asset to the lessee by the end of the lease term, (b) review to determine if the lease grants the lessee a purchase option that the lessee is reasonably certain to exercise, (c) determine, using a seventy-five percent or more threshold, if the lease term is for a major part of the remaining economic life of the underlying asset (however, we do not use this classification criterion when the lease commencement date falls within the last 25 percent of the total economic life of the underlying asset) and (d) determine, using a 90 percent or more threshold, if the present value of the sum of the lease payments and any residual value guarantees equal or exceeds substantially all of the fair value of the underlying asset. We do not lease equipment of such a specialized nature that it is expected to have no alternative use to the lessor at the end of the lease term. Each of our leases is classified as an operating lease.

We elected the operating lease practical expedient for its leases to not separate non-lease components of regular maintenance services from associated lease components. This practical expedient is available when both of the following are met: (i) the timing and pattern of transfer of the non-lease components and associated lease component are the same and (ii) the lease component, if accounted for separately, would be classified as an operating lease.

Financial instruments, which potentially subject us to concentrations of credit risk, consist primarily of cash and cash equivalents and accounts receivable. We limit our exposure to credit loss by generally placing cash in high credit quality financial institutions. Cash balances are maintained primarily at major financial institutions in the United States and a portion of which exceed the regulatory limit of $250,000 insured by the Federal Deposit Insurance Corporation (FDIC). We have not experienced any credit losses associated with our cash balances. Additionally, we have established guidelines regarding diversification of our investments and their maturities, which are designed to maintain principal and maximize liquidity.

We determine at the inception of each arrangement whether an entity in which we have made an investment or in which we have other variable interests is considered a variable interest entity (“VIE”). We consolidate VIEs when we are the primary beneficiary. We are the primary beneficiary of a VIE when we have the power to direct activities that most significantly affect the economic performance of the VIE and have the obligation to absorb the significant losses or benefits. If we are not the primary beneficiary in a VIE, we account for the investment or other variable interests in a VIE in accordance with applicable GAAP.

PPP Loan forgiveness reclassification has been made to the prior period financial statements to conform to the current year financial statement presentation of the condensed Consolidated Statements of Operations. This change did not impact previously reported net loss, loss per share, stockholders’ equity, total assets or the condensed Consolidated Statements of Cash Flows.

Finance Lease liabilities and Investments reclassifications have been made to the prior period financial statements to conform to the current year financial statement presentation of the condensed Consolidated Balance Sheets. These changes did not impact previously reported net (loss) income, (loss) income per share, stockholders’ equity, total liabilities, total assets or the condensed Consolidated Statements of Cash Flows.

In June 2016, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2016-13, Financial Instruments - Credit Losses: Measurement of Credit Losses on Financial Instruments, which amends the impairment model by requiring entities to use a forward-looking approach based on expected losses to estimate credit losses on certain types of financial instruments, including trade receivables and available-for-sale debt securities. This update is effective for annual periods beginning after December 15, 2022, and interim periods within those periods, and early adoption is permitted. We expect to adopt the standard on its effective date in the first quarter of 2023. We believe the adoption will modify the way we analyze financial instruments, but currently do not expect the adoption to have a material financial impact on our condensed consolidated financial statements.

In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848), to temporarily ease the potential burden in accounting for reference rate reform. The standard provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships and other transactions affected by reference rate reform. The guidance generally can be applied through December 31, 2022. We will monitor our contracts and transactions for potential application of this ASU.

In August 2020, the FASB issued ASU No. 2020-06, Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40). ASU 2020-06 eliminates the beneficial conversion and cash conversion accounting models for convertible instruments. It also amends the accounting for certain contracts in an entity’s own equity that are currently accounted for as derivatives because of specific settlement provisions. In addition, ASU 2020-06 modifies how particular convertible instruments and certain contracts that may be settled in cash or shares impact the diluted EPS computation. The amendments in this update are effective for public business entities for fiscal years beginning after December 15, 2021 (or December 15, 2023 for companies who meet the SEC definition of Smaller Reporting Companies), and interim periods within those fiscal years. The amendment is to be adopted through either a fully retrospective or modified retrospective method of transition. Early adoption is permitted. The Company early adopted this standard on January 1, 2021 by applying the modified retrospective approach. There was no cumulative-effect transition adjustment required to the opening balance of accumulated deficit upon the adoption of this standard.
