Coronavirus Aid, Relief, and Economic Security Act On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security (CARES) Act (the “Act”) was enacted. The CARES Act is an emergency economic stimulus package in response to the Coronavirus outbreak, which among other things contains numerous income tax provisions. Some of these tax provisions were retroactively effective for years ending before the date of enactment. In April 2020, the Company applied for, and received, funds under the Paycheck Protection Program in the amount of $781,800. The Company applied for forgiveness, and on November 20, 2020, received confirmation that the amount had been forgiven. The loan balance plus accrued interest of $<span id="xdx_90B_eus-gaap--GainsLossesOnExtinguishmentOfDebt_pp0p0_c20200101__20201231__us-gaap--TypeOfArrangementAxis__custom--PaycheckProtectionProgramMember_z25IeLpbpgCe" title="Gain on extinguishment of debt">786,889 was recorded as a gain on extinguishment of debt in the December 31, 2020 consolidate statement of operations. Refer to Note 11. Principles of Consolidation The accompanying consolidated financial statements include the accounts of CareView and CareView Communications, Inc., a Texas corporation and CareView Operations, LLC, a Nevada limited liability company (our wholly owned subsidiaries).

NOTE 2 – SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Cash and Cash Equivalents We consider all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents. We maintain cash at financial institutions that at times may exceed federally insured limits. Trade Accounts Receivable Trade accounts receivable are customer obligations due under normal trade terms. We provide an allowance for doubtful accounts, which is based upon a review of outstanding receivables, historical collection information and existing economic conditions. Trade accounts receivable past due more than 90 days are considered delinquent. Delinquent receivables are written off based on individual credit evaluations, results of collection efforts, and specific circumstances of the customer. Recoveries of accounts previously written off are recorded as reductions of bad debt expense when received. At December 31, 2021 and 2020, an allowance for doubtful accounts of $0 and $0, respectively, was recorded. Property and Equipment Property and equipment is stated at cost, net of accumulated depreciation. Maintenance costs, which do not significantly extend the useful lives of the respective assets, and repair costs are charged to operating expense as incurred. We include network equipment in fixed assets upon receipt and begin depreciating such equipment when it passes our incoming inspection and is available for use. We attribute no salvage value to the network equipment and depreciation is computed using the straight-line method based on the estimated useful life of <span id="xdx_906_eus-gaap--PropertyPlantAndEquipmentUsefulLife_dt_c20210101__20211231__us-gaap--PropertyPlantAndEquipmentByTypeAxis__custom--NetworkEquipmentMember_z8dyucTP5vK8" title="Estimated useful life of property and equipment">seven years. Depreciation of office and test equipment, warehouse equipment and furniture is computed using the straight-line method based on the estimated useful lives of the assets, generally three years for office and test equipment, and five years for warehouse equipment and furniture. Inventories Inventory is valued at the lower of cost, determined on a first-in, first-out (FIFO), or net realizable value. Inventory items are analyzed to determine cost and net realizable value, and appropriate valuation adjustments are then established. See Note 6 for more details. Allowance for System Removal On occasion, the Company will remove subscription equipment from its larger customer premises due to contract expiration/non-renewal. When equipment is removed an allowance is established based on the estimated cost of removal. At December 31, 2021 and 2020, an allowance of $54,802 and $36,500, respectively, was recorded in other assets in the accompanying consolidated financial statements. Impairment of Long-Lived Assets Carrying values of property and equipment and finite-lived intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that their carrying values may not be recoverable. Such events or circumstances include, but are not limited to: <table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; margin-top: 0pt; margin-bottom: 0pt"><tr style="font: 10pt Times New Roman, Times, Serif; vertical-align: top"> <td style="font: 10pt Times New Roman, Times, Serif; width: 0.5in"/><td style="font: 10pt Times New Roman, Times, Serif; width: 0.25in">●</td><td style="font: 10pt Times New Roman, Times, Serif; text-align: justify">significant declines in an asset’s market price;</td></tr></table> <table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; margin-top: 0pt; margin-bottom: 0pt"><tr style="font: 10pt Times New Roman, Times, Serif; vertical-align: top"> <td style="font: 10pt Times New Roman, Times, Serif; width: 0.5in"/><td style="font: 10pt Times New Roman, Times, Serif; width: 0.25in">●</td><td style="font: 10pt Times New Roman, Times, Serif; text-align: justify">significant deterioration in an asset’s physical condition;</td></tr></table> <table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; margin-top: 0pt; margin-bottom: 0pt"><tr style="font: 10pt Times New Roman, Times, Serif; vertical-align: top"> <td style="font: 10pt Times New Roman, Times, Serif; width: 0.5in"/><td style="font: 10pt Times New Roman, Times, Serif; width: 0.25in">●</td><td style="font: 10pt Times New Roman, Times, Serif; text-align: justify">significant changes in the nature or extent of an asset’s use or operation;</td></tr></table> <table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; margin-top: 0pt; margin-bottom: 0pt"><tr style="font: 10pt Times New Roman, Times, Serif; vertical-align: top"> <td style="font: 10pt Times New Roman, Times, Serif; width: 0.5in"/><td style="font: 10pt Times New Roman, Times, Serif; width: 0.25in">●</td><td style="font: 10pt Times New Roman, Times, Serif; text-align: justify">significant adverse changes in the business climate that could impact an asset’s value, including adverse actions or assessments by regulators;</td></tr></table> <table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; margin-top: 0pt; margin-bottom: 0pt"><tr style="font: 10pt Times New Roman, Times, Serif; vertical-align: top"> <td style="font: 10pt Times New Roman, Times, Serif; width: 0.5in"/><td style="font: 10pt Times New Roman, Times, Serif; width: 0.25in">●</td><td style="font: 10pt Times New Roman, Times, Serif; text-align: justify">accumulation of costs significantly in excess of original expectations related to the acquisition or construction of an asset;</td></tr></table> <table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; margin-top: 0pt; margin-bottom: 0pt"><tr style="font: 10pt Times New Roman, Times, Serif; vertical-align: top"> <td style="font: 10pt Times New Roman, Times, Serif; width: 0.5in"/><td style="font: 10pt Times New Roman, Times, Serif; width: 0.25in">●</td><td style="font: 10pt Times New Roman, Times, Serif; text-align: justify">current-period operating, or cash flow losses combined with a history of such losses, or a forecast that demonstrates continuing losses associated with an asset’s use; and</td></tr></table> <table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; margin-top: 0pt; margin-bottom: 0pt"><tr style="font: 10pt Times New Roman, Times, Serif; vertical-align: top"> <td style="font: 10pt Times New Roman, Times, Serif; width: 0.5in"/><td style="font: 10pt Times New Roman, Times, Serif; width: 0.25in">●</td><td style="font: 10pt Times New Roman, Times, Serif; text-align: justify">expectations that it is more likely than not that an asset will be sold or otherwise disposed of significantly before the end of our previously estimated useful life.</td></tr></table> If impairment indicators are present, we determine whether an impairment loss should be recognized by testing the applicable asset or asset groups’ carrying value for recoverability. This test requires long-lived assets to be grouped at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities, the determination of which requires judgment. We estimate the undiscounted future cash flows expected to be generated from the use and eventual disposal of the assets and compare that estimate to the respective carrying values in order to determine if such carrying values are recoverable. This assessment requires the exercise of judgment in assessing the future use of and projected value to be derived from the eventual disposal of the assets to be held and used. Assessments also consider changes in asset utilization, including the temporary idling of capacity and the expected timing for placing this capacity back into production. If the carrying value of the asset is not recoverable, then a loss is recorded for the difference between the assets’ fair value and respective carrying value. The fair value of the asset is determined using an “income approach” based upon a forecast of all the expected discounted future net cash flows associated with the subject assets. Some of the more significant estimates and assumptions include market size and growth, market share, projected selling prices, manufacturing cost and discount rate. Our estimates are based upon our past experience, our commercial relationships, market conditions and available external information about future trends. We believe our current assumptions and estimates are reasonable and appropriate; however, unanticipated events and changes in market conditions could affect such estimates resulting in the need for an impairment charge in future periods. During the years ended December 31, 2021 and 2020, no impairment was recognized. Research and Development Research and development costs are expensed as incurred. Costs regarding the development of software to be sold, leased or otherwise marketed are subject to capitalization beginning when a product’s technological feasibility has been established and ending when a product is available for general release to customers. We did not capitalize any such costs during the years ended December 31, 2021, and 2020. Intellectual Property We capitalize certain costs of developing software upon the establishment of technological feasibility and prior to the availability of the product for general release to customers for our CareView Patient Safety System in accordance with GAAP. Capitalized costs are reported at the lower of unamortized cost or net realizable value and are amortized over the estimated useful life of the CareView Patient Safety System not to exceed <span id="xdx_90E_eus-gaap--FiniteLivedIntangibleAssetUsefulLife_dt_c20210101__20211231__us-gaap--FiniteLivedIntangibleAssetsByMajorClassAxis__us-gaap--IntellectualPropertyMember__srt--RangeAxis__srt--MaximumMember_zlgJVlAhEhx5" title="Amortization period for intangible assets">five years. Additionally, we test our intangible assets for impairment whenever circumstances indicate that their carrying value may not be recoverable. No impairment was recorded during the years ended December 31, 2021, and 2020. During the years ended December 31, 2021, and 2020, we capitalized no additional intellectual property costs. Patents and Trademarks We amortize our intangible assets with a finite life on a straight-line basis, over 10 years for trademarks and 20 years for patents. We begin amortization of these costs on the date patents or trademarks are awarded. Fair Value of Financial Instruments Our financial instruments consist primarily of receivables, accounts payable, accrued expenses and short and long-term debt. The carrying amount of receivables, accounts payable and accrued expenses approximate our fair value because of the short-term maturity of such instruments, and they are considered Level 1 assets under the fair value hierarchy. We have elected not to carry our debt instruments at fair value. The carrying amount of our debt approximates fair value. Interest rates that are currently available to us for issuance of short- and long-term debt with similar terms. Remaining maturities are used to estimate the fair value of our short- and long-term debt and would be considered Level 3 inputs under the fair value hierarchy. We have categorized our assets and liabilities that are valued at fair value on a recurring basis into a three-level fair value hierarchy in accordance with GAAP. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets and liabilities (Level 1) and lowest priority to unobservable inputs (Level 3). Assets and liabilities recorded in the consolidated balance sheets at fair value are categorized based on a hierarchy of inputs, as follows: Level 1 -- Unadjusted quoted prices in active markets for identical assets or liabilities. Level 2 -- Quoted prices for similar assets or liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument. Level 3 -- Unobservable inputs for the asset or liability. At December 31, 2021, and 2020, we had no financial assets and liabilities reported at fair value. Income Taxes Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statements carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which the related temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized when the rate change is enacted. Valuation allowances are recorded to reduce deferred tax assets to the amount that will more likely than not be realized. In accordance with GAAP, we recognize the effect of uncertain income tax positions only if the positions are more likely than not of being sustained in an audit, based on the technical merits of the position. Recognized uncertain income tax positions are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the period in which those changes in judgement occur. We recognize both interest and penalties related to uncertain tax positions as part of the income tax provision. Revenue Recognition We recognize revenue in accordance with Accounting Standards Codification (“ASC”) Topic 606 (“ASC 606”). For our subscription service contracts, we have employed the practical expedient discussed in ASC 606-10-55-18 related to invoicing as we have the right to consideration from our customers in the amount that corresponds directly with the value to the customer of our performance completed to date and therefore, we recognize revenue upon invoicing as further discussed below. In accordance with ASC 606, revenue is recognized when a customer obtains control of promised goods or services. The amount of revenue recognized reflects the consideration to which we expect to be entitled to receive in exchange for these goods or services. The provisions of ASC 606 include a five-step process by which we determine revenue recognition, depicting the transfer of goods or services to customers in amounts reflecting the payment to which we expect to be entitled in exchange for those goods or services. ASC 606 requires us to apply the following steps: (1) identify the contract with the customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue when, or as, we satisfy the performance obligation. For those customers for which we are required to collect sales taxes, we record such sales taxes on a net basis which has no effect on the amount of revenue or expenses recognized as the sales taxes are a flow through to the taxing authority. We enter into contracts with customers that may provide multiple combinations of our products, software solutions, and other related services, which are generally capable of being distinct and accounted for as separate performance obligations. Performance obligations that are not distinct at contract inception are combined. Customer contract fulfillment typically involves multiple procurement promises, which may include various equipment, software subscription, project-related installation and training services, and support. We allocate the transaction price to each performance obligation based on estimated relative standalone selling price. Revenue is then recognized for each performance obligation upon transferring control of the hardware, software, and services to the customer and in an amount that reflects the consideration we expect to receive and the estimated benefit the customer receives over the term of the contract. Generally, we recognize revenue under each of our performance obligations as follows: <table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; margin-top: 0pt;

Determining whether the various contract promises are considered distinct performance obligations that should be accounted for separately versus together may require significant judgment. Contract transaction price is allocated to distinct performance obligations using estimated standalone selling price. We determine standalone selling price maximizing observable inputs such as standalone sales, competitor standalone sales, or substantive renewal prices charged to customers when they exist. In instances where standalone selling price is not observable, we utilize an estimate of standalone selling price. Such estimates are derived from various methods that include cost plus margin, and historical pricing practices. Judgment may be required to determine standalone selling prices for each performance obligation and whether it depicts the amount we expect to receive in exchange for the related good or service. Contract modifications occur when we and our customers agree to modify existing customer contracts to change the scope or price (or both) of the contract or when a customer terminates some, or all, of the existing services provided by us. When a contract modification occurs, it requires us to exercise judgment to determine if the modification should be accounted for as a separate contract, the termination of the original contract and creation of a new contract, a cumulative catch-up adjustment to the original contract, or a combination. Contracts with our customers include a limited warranty on our products covering materials, workmanship, or design for the duration of contract. We do not offer paid additional extended or lifetime warranty packages. We determined the limited warranty in our contract is not a distinct performance obligation. We do not believe our estimates of warranty costs to be significant to our determination of revenue recognition and, therefore, did not reserve for warranty costs. Leases The Company has an operating lease primarily consisting of office space with a remaining lease term of 43 months. At the lease commencement date, an operating lease liability and related operating lease asset are recognized. The operating lease liabilities are calculated using the present value of lease payments. The discount rate used is either the rate implicit in the lease, when known, or our estimated incremental borrowing rate. Operating lease assets are valued based on the initial operating lease liabilities plus any prepaid rent and direct costs from executing the leases Earnings Per Share We calculate earnings per share (“EPS”) in accordance with GAAP, which requires the computation and disclosure of two EPS amounts, basic and diluted. Basic EPS is computed based on the weighted average number of common shares outstanding during the period. Diluted EPS is computed based on the weighted average number of common shares outstanding plus all potentially dilutive common shares outstanding during the period under the treasury stock method. Such potential dilutive common shares consist of stock options, warrants to purchase our Common Stock (the “Warrants”) and convertible debt. Potential common shares totaling approximately<span id="xdx_904_eus-gaap--AntidilutiveSecuritiesExcludedFromComputationOfEarningsPerShareAmount_pid_c20210101__20211231_zg7qo1wh06i8" title="Anti-dilutive common share equivalents excluded from EPS calculation"> 226,000,000 and 207,000,000 at December 31, 2021, and 2020, respectively, have been excluded from the diluted earnings per share calculation as they are anti-dilutive due to our reported net loss. Stock Based Compensation We recognize compensation expense for all share-based payments granted and amended based on the grant date fair value estimated in accordance with GAAP. Compensation expense is generally recognized on a straight-line basis over the employee’s requisite service period based on the award’s estimated lives for fixed awards with ratable vesting provisions. Debt Discount Costs Costs incurred with parties who are providing long-term financing, with Warrants issued with the underlying debt, are reflected as a debt discount based on the relative fair value of the debt and Warrants. These discounts are generally amortized over the life of the related debt, using the effective interest rate method or other methods approximating the effective interest method. Additionally, convertible debt issued with a beneficial conversion feature is recorded at a discount based on the difference in the effective conversion price and the fair value of the Company’s stock on the date of issuance, if any. Outstanding debt is presented net of any such discounts on the accompanying consolidated financial statements. Deferred Debt Issuance and Debt Financing Costs Costs incurred through the issuance of Warrants to parties who are providing long-term financing availability, which includes revolving credit lines, are reflected as deferred debt issuance based on the fair value of the Warrants issued. Costs incurred with third parties related to issuance of debt are recorded as deferred financing costs. These costs are generally amortized over the life of the financing instrument using the effective interest rate method or other methods approximating the effective interest method. Amounts associated with our senior secured convertible notes are netted with the outstanding debt on the accompanying consolidated financial statements while amount associated with credit facilities are presented in other assets on the accompanying consolidated statements of operations. Shipping and Handling Costs We expense all shipping and handling costs as incurred. These costs are included in network operations on the accompanying consolidated statements of operations. Advertising Costs We consider advertising costs as costs associated with the promotion of our products through the various media outlets and trade shows. We expense all advertising costs as incurred. Our advertising expense for the years ended December 31, 2021, and 2020, totaled approximately $33,000 and $30,000, respectively. Concentration of Credit Risks and Customer Data During 2021, no customer comprised more than 10% of our revenue.

Use of Estimates Our financial statements have been prepared in accordance with GAAP. The preparation of these financial statements requires us to make significant estimates and judgments that affect the reported amounts of assets, liabilities, revenues, expenses and related disclosure of contingent assets and liabilities. We evaluate our estimates, including those related to contingencies, on an ongoing basis. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. Recently Issued and Newly Adopted Accounting Pronouncements In August 2020, the FASB issued ASU 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”). ASU 2020-06 simplifies the accounting for certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts on an entity’s own equity. The ASU 2020-06 amendments are effective for fiscal years beginning after December 15, 2023, and interim periods within those fiscal years. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. The Company is currently evaluating the impact of adopting this standard. In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-13, Financial Instruments — Credit Losses (Topic 326) (“ASU 2016-13”). ASU 2016-13 modifies the measurement of expected credit losses of certain financial instruments, requiring entities to estimate an expected lifetime credit loss on financial assets. The ASU amends the impairment model to utilize an expected loss methodology and replaces the incurred loss methodology for financial instruments including trade receivables. The amendment requires entities to consider other factors, such as historical loss experience, current conditions and reasonable and supportable forecasts. In November 2019, the FASB issued ASU No. 2019-10, Financial Instruments - Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842): Effective Dates, which deferred the effective date of the new guidance by one year to fiscal years beginning after December 15, 2022, with early adoption permitted. The Company is evaluating the impact of adopting the new accounting standards on its consolidated financial statements.

Cash and Cash Equivalents We consider all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents. We maintain cash at financial institutions that at times may exceed federally insured limits.

Trade Accounts Receivable Trade accounts receivable are customer obligations due under normal trade terms. We provide an allowance for doubtful accounts, which is based upon a review of outstanding receivables, historical collection information and existing economic conditions. Trade accounts receivable past due more than 90 days are considered delinquent. Delinquent receivables are written off based on individual credit evaluations, results of collection efforts, and specific circumstances of the customer. Recoveries of accounts previously written off are recorded as reductions of bad debt expense when received. At December 31, 2021 and 2020, an allowance for doubtful accounts of $0 and $0, respectively, was recorded.

Property and Equipment Property and equipment is stated at cost, net of accumulated depreciation. Maintenance costs, which do not significantly extend the useful lives of the respective assets, and repair costs are charged to operating expense as incurred. We include network equipment in fixed assets upon receipt and begin depreciating such equipment when it passes our incoming inspection and is available for use. We attribute no salvage value to the network equipment and depreciation is computed using the straight-line method based on the estimated useful life of <span id="xdx_906_eus-gaap--PropertyPlantAndEquipmentUsefulLife_dt_c20210101__20211231__us-gaap--PropertyPlantAndEquipmentByTypeAxis__custom--NetworkEquipmentMember_z8dyucTP5vK8" title="Estimated useful life of property and equipment">seven years. Depreciation of office and test equipment, warehouse equipment and furniture is computed using the straight-line method based on the estimated useful lives of the assets, generally three years for office and test equipment, and five years for warehouse equipment and furniture.

Inventories Inventory is valued at the lower of cost, determined on a first-in, first-out (FIFO), or net realizable value. Inventory items are analyzed to determine cost and net realizable value, and appropriate valuation adjustments are then established. See Note 6 for more details.

Allowance for System Removal On occasion, the Company will remove subscription equipment from its larger customer premises due to contract expiration/non-renewal. When equipment is removed an allowance is established based on the estimated cost of removal. At December 31, 2021 and 2020, an allowance of $54,802 and $36,500, respectively, was recorded in other assets in the accompanying consolidated financial statements. 54802 36500

Impairment of Long-Lived Assets Carrying values of property and equipment and finite-lived intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that their carrying values may not be recoverable.

This test requires long-lived assets to be grouped at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities, the determination of which requires judgment. We estimate the undiscounted future cash flows expected to be generated from the use and eventual disposal of the assets and compare that estimate to the respective carrying values in order to determine if such carrying values are recoverable. This assessment requires the exercise of judgment in assessing the future use of and projected value to be derived from the eventual disposal of the assets to be held and used. Assessments also consider changes in asset utilization, including the temporary idling of capacity and the expected timing for placing this capacity back into production. If the carrying value of the asset is not recoverable, then a loss is recorded for the difference between the assets’ fair value and respective carrying value. The fair value of the asset is determined using an “income approach” based upon a forecast of all the expected discounted future net cash flows associated with the subject assets. Some of the more significant estimates and assumptions include market size and growth, market share, projected selling prices, manufacturing cost and discount rate. Our estimates are based upon our past experience, our commercial relationships, market conditions and available external information about future trends. We believe our current assumptions and estimates are reasonable and appropriate; however, unanticipated events and changes in market conditions could affect such estimates resulting in the need for an impairment charge in future periods. During the years ended December 31, 2021 and 2020, no impairment was recognized.

Research and Development Research and development costs are expensed as incurred. Costs regarding the development of software to be sold, leased or otherwise marketed are subject to capitalization beginning when a product’s technological feasibility has been established and ending when a product is available for general release to customers. We did not capitalize any such costs during the years ended December 31, 2021, and 2020.

Intellectual Property We capitalize certain costs of developing software upon the establishment of technological feasibility and prior to the availability of the product for general release to customers for our CareView Patient Safety System in accordance with GAAP. Capitalized costs are reported at the lower of unamortized cost or net realizable value and are amortized over the estimated useful life of the CareView Patient Safety System not to exceed <span id="xdx_90E_eus-gaap--FiniteLivedIntangibleAssetUsefulLife_dt_c20210101__20211231__us-gaap--FiniteLivedIntangibleAssetsByMajorClassAxis__us-gaap--IntellectualPropertyMember__srt--RangeAxis__srt--MaximumMember_zlgJVlAhEhx5" title="Amortization period for intangible assets">five years. Additionally, we test our intangible assets for impairment whenever circumstances indicate that their carrying value may not be recoverable. No impairment was recorded during the years ended December 31, 2021, and 2020. During the years ended December 31, 2021, and 2020, we capitalized no additional intellectual property costs.

Fair Value of Financial Instruments Our financial instruments consist primarily of receivables, accounts payable, accrued expenses and short and long-term debt. The carrying amount of receivables, accounts payable and accrued expenses approximate our fair value because of the short-term maturity of such instruments, and they are considered Level 1 assets under the fair value hierarchy. We have elected not to carry our debt instruments at fair value. The carrying amount of our debt approximates fair value. Interest rates that are currently available to us for issuance of short- and long-term debt with similar terms. Remaining maturities are used to estimate the fair value of our short- and long-term debt and would be considered Level 3 inputs under the fair value hierarchy. We have categorized our assets and liabilities that are valued at fair value on a recurring basis into a three-level fair value hierarchy in accordance with GAAP. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets and liabilities (Level 1) and lowest priority to unobservable inputs (Level 3). Assets and liabilities recorded in the consolidated balance sheets at fair value are categorized based on a hierarchy of inputs, as follows: Level 1 -- Unadjusted quoted prices in active markets for identical assets or liabilities. Level 2 -- Quoted prices for similar assets or liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument. Level 3 -- Unobservable inputs for the asset or liability. At December 31, 2021, and 2020, we had no financial assets and liabilities reported at fair value.

Income Taxes Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statements carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which the related temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized when the rate change is enacted. Valuation allowances are recorded to reduce deferred tax assets to the amount that will more likely than not be realized. In accordance with GAAP, we recognize the effect of uncertain income tax positions only if the positions are more likely than not of being sustained in an audit, based on the technical merits of the position. Recognized uncertain income tax positions are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the period in which those changes in judgement occur. We recognize both interest and penalties related to uncertain tax positions as part of the income tax provision.

Revenue Recognition We recognize revenue in accordance with Accounting Standards Codification (“ASC”) Topic 606 (“ASC 606”). For our subscription service contracts, we have employed the practical expedient discussed in ASC 606-10-55-18 related to invoicing as we have the right to consideration from our customers in the amount that corresponds directly with the value to the customer of our performance completed to date and therefore, we recognize revenue upon invoicing as further discussed below. In accordance with ASC 606, revenue is recognized when a customer obtains control of promised goods or services. The amount of revenue recognized reflects the consideration to which we expect to be entitled to receive in exchange for these goods or services. The provisions of ASC 606 include a five-step process by which we determine revenue recognition, depicting the transfer of goods or services to customers in amounts reflecting the payment to which we expect to be entitled in exchange for those goods or services. ASC 606 requires us to apply the following steps: (1) identify the contract with the customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue when, or as, we satisfy the performance obligation. For those customers for which we are required to collect sales taxes, we record such sales taxes on a net basis which has no effect on the amount of revenue or expenses recognized as the sales taxes are a flow through to the taxing authority. We enter into contracts with customers that may provide multiple combinations of our products, software solutions, and other related services, which are generally capable of being distinct and accounted for as separate performance obligations. Performance obligations that are not distinct at contract inception are combined. Customer contract fulfillment typically involves multiple procurement promises, which may include various equipment, software subscription, project-related installation and training services, and support. We allocate the transaction price to each performance obligation based on estimated relative standalone selling price. Revenue is then recognized for each performance obligation upon transferring control of the hardware, software, and services to the customer and in an amount that reflects the consideration we expect to receive and the estimated benefit the customer receives over the term of the contract. Generally, we recognize revenue under each of our performance obligations as follows: <table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; margin-top: 0pt;

Determining whether the various contract promises are considered distinct performance obligations that should be accounted for separately versus together may require significant judgment. Contract transaction price is allocated to distinct performance obligations using estimated standalone selling price. We determine standalone selling price maximizing observable inputs such as standalone sales, competitor standalone sales, or substantive renewal prices charged to customers when they exist. In instances where standalone selling price is not observable, we utilize an estimate of standalone selling price. Such estimates are derived from various methods that include cost plus margin, and historical pricing practices. Judgment may be required to determine standalone selling prices for each performance obligation and whether it depicts the amount we expect to receive in exchange for the related good or service. Contract modifications occur when we and our customers agree to modify existing customer contracts to change the scope or price (or both) of the contract or when a customer terminates some, or all, of the existing services provided by us. When a contract modification occurs, it requires us to exercise judgment to determine if the modification should be accounted for as a separate contract, the termination of the original contract and creation of a new contract, a cumulative catch-up adjustment to the original contract, or a combination. Contracts with our customers include a limited warranty on our products covering materials, workmanship, or design for the duration of contract. We do not offer paid additional extended or lifetime warranty packages. We determined the limited warranty in our contract is not a distinct performance obligation. We do not believe our estimates of warranty costs to be significant to our determination of revenue recognition and, therefore, did not reserve for warranty costs.

Leases The Company has an operating lease primarily consisting of office space with a remaining lease term of 43 months. At the lease commencement date, an operating lease liability and related operating lease asset are recognized. The operating lease liabilities are calculated using the present value of lease payments. The discount rate used is either the rate implicit in the lease, when known, or our estimated incremental borrowing rate. Operating lease assets are valued based on the initial operating lease liabilities plus any prepaid rent and direct costs from executing the leases

Earnings Per Share We calculate earnings per share (“EPS”) in accordance with GAAP, which requires the computation and disclosure of two EPS amounts, basic and diluted. Basic EPS is computed based on the weighted average number of common shares outstanding during the period. Diluted EPS is computed based on the weighted average number of common shares outstanding plus all potentially dilutive common shares outstanding during the period under the treasury stock method. Such potential dilutive common shares consist of stock options, warrants to purchase our Common Stock (the “Warrants”) and convertible debt. Potential common shares totaling approximately<span id="xdx_904_eus-gaap--AntidilutiveSecuritiesExcludedFromComputationOfEarningsPerShareAmount_pid_c20210101__20211231_zg7qo1wh06i8" title="Anti-dilutive common share equivalents excluded from EPS calculation"> 226,000,000 and 207,000,000 at December 31, 2021, and 2020, respectively, have been excluded from the diluted earnings per share calculation as they are anti-dilutive due to our reported net loss.

Stock Based Compensation We recognize compensation expense for all share-based payments granted and amended based on the grant date fair value estimated in accordance with GAAP. Compensation expense is generally recognized on a straight-line basis over the employee’s requisite service period based on the award’s estimated lives for fixed awards with ratable vesting provisions.

Debt Discount Costs Costs incurred with parties who are providing long-term financing, with Warrants issued with the underlying debt, are reflected as a debt discount based on the relative fair value of the debt and Warrants. These discounts are generally amortized over the life of the related debt, using the effective interest rate method or other methods approximating the effective interest method. Additionally, convertible debt issued with a beneficial conversion feature is recorded at a discount based on the difference in the effective conversion price and the fair value of the Company’s stock on the date of issuance, if any. Outstanding debt is presented net of any such discounts on the accompanying consolidated financial statements.

Deferred Debt Issuance and Debt Financing Costs Costs incurred through the issuance of Warrants to parties who are providing long-term financing availability, which includes revolving credit lines, are reflected as deferred debt issuance based on the fair value of the Warrants issued. Costs incurred with third parties related to issuance of debt are recorded as deferred financing costs. These costs are generally amortized over the life of the financing instrument using the effective interest rate method or other methods approximating the effective interest method. Amounts associated with our senior secured convertible notes are netted with the outstanding debt on the accompanying consolidated financial statements while amount associated with credit facilities are presented in other assets on the accompanying consolidated statements of operations.

Shipping and Handling Costs We expense all shipping and handling costs as incurred. These costs are included in network operations on the accompanying consolidated statements of operations.

Advertising Costs We consider advertising costs as costs associated with the promotion of our products through the various media outlets and trade shows. We expense all advertising costs as incurred. Our advertising expense for the years ended December 31, 2021, and 2020, totaled approximately $33,000 and $30,000, respectively.

Use of Estimates Our financial statements have been prepared in accordance with GAAP. The preparation of these financial statements requires us to make significant estimates and judgments that affect the reported amounts of assets, liabilities, revenues, expenses and related disclosure of contingent assets and liabilities. We evaluate our estimates, including those related to contingencies, on an ongoing basis. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

Recently Issued and Newly Adopted Accounting Pronouncements In August 2020, the FASB issued ASU 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”). ASU 2020-06 simplifies the accounting for certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts on an entity’s own equity. The ASU 2020-06 amendments are effective for fiscal years beginning after December 15, 2023, and interim periods within those fiscal years. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. The Company is currently evaluating the impact of adopting this standard. In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-13, Financial Instruments — Credit Losses (Topic 326) (“ASU 2016-13”). ASU 2016-13 modifies the measurement of expected credit losses of certain financial instruments, requiring entities to estimate an expected lifetime credit loss on financial assets. The ASU amends the impairment model to utilize an expected loss methodology and replaces the incurred loss methodology for financial instruments including trade receivables. The amendment requires entities to consider other factors, such as historical loss experience, current conditions and reasonable and supportable forecasts. In November 2019, the FASB issued ASU No. 2019-10, Financial Instruments - Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842): Effective Dates, which deferred the effective date of the new guidance by one year to fiscal years beginning after December 15, 2022, with early adoption permitted. The Company is evaluating the impact of adopting the new accounting standards on its consolidated financial statements.

NOTE 3 – GOING CONCERN, LIQUIDITY AND MANAGMENTS PLAN Accounting standards require management to evaluate our ability to continue as a going concern for a period of one year after the date of the filing of this Form 10-K (“evaluation period”). In evaluating the Company’s ability to continue as a going concern, Management considers the conditions and events that raise substantial doubt about the Company’s ability to continue as a going concern for a period of twelve months after the Company issues its financial statements. For the year ended December 31, 2021, Management considers the Company’s current financial condition and liquidity sources, including current funds available, forecasted future cash flows, and the Company’s conditional and unconditional obligations due within 12 months of the date these financial statements are issued. The Company is subject to risks like those of healthcare technology companies whereby revenues are generated based on both sales-based and subscription-based models, which assume dependence on key individuals, uncertainty of product development, generation of revenues, positive cash flow, dependence on outside sources of capital, risks associated with research, development, and successful testing of its products, successful protection of intellectual property, ability to maintain and grow its customer base, and susceptibility to infringement on the proprietary rights of others. The attainment of profitable operations is dependent on future events, including obtaining adequate financing to fulfill the Company’s growth and operating activities and generating a level of revenues adequate to support the Company’s cost structure. As of the year ended December 31, 2021, the Company had cash and a working capital deficit of approximately $87,062,000 consisting primarily of notes payables and senior secured notes. Management has evaluated the significance of the conditions described above in relation to the Company’s ability to meet its obligations and concluded that, without additional funding, the Company will not have sufficient funds to meet its obligations within one year from the date the consolidated financial statements were issued. While management will look to continue funding operations by increased sales volumes and raising additional capital from sources such as sales of its debt or equity securities or loans to meet operating cash requirements, there is no assurance that management’s plans will be successful. Management continues to monitor the immediate and future cash flows needs of the company in a variety of ways which include forecasted net cash flows from operations, capital expenditure control, new inventory orders, debt modifications, increases sales outreach, streamlining and controlling general and administrative costs, competitive industry pricing, sale of equities, debt conversions, new product or services offerings, and new business partnerships. The Company’s net losses, cash outflows, and working capital deficit raise substantial doubt is about the Company’s ability to continue as a going concern. The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. This basis of accounting contemplates the recovery of the Company’s assets and the satisfaction of liabilities in the normal course of business. A successful transition to attaining profitable operations is dependent upon achieving a level of positive cash flows adequate to support the Company’s cost structure. 87062000

NOTE 4 – STOCKHOLDERS’ EQUITY Preferred Stock At December 31, 2021, and 2020, we had 20,000,000 shares of Preferred Stock, par value $0.001 authorized, and zero shares outstanding, which can be designated by our Board of Directors. Common Stock At December 31, 2021, and 2020, we had 500,000,000 shares of Common Stock, $0.001 par value, respectively, authorized, and 139,380,748 shares of Common Stock issued and outstanding. There was no Common Stock issued during the years ended December 31, 2021, and 2020. Warrants to Purchase Common Stock of the Company We use the Black-Scholes-Merton option pricing model (“Black-Scholes Model”) to determine the fair value of Warrants. The Black-Scholes Model requires the use of a number of assumptions including volatility of the stock price, the weighted average risk-free interest rate, and the weighted average term of the Warrant. The risk-free interest rate assumption is based upon observed interest rates on zero coupon U.S. Treasury bonds whose maturity period is appropriate for the term of the Warrants and is calculated by using the average daily historical stock prices through the day preceding the grant date. Estimated volatility is a measure of the amount by which our stock price is expected to fluctuate each year during the expected life of the award. Our estimated volatility is an average of the historical volatility of our stock prices (and that of peer entities whose stock prices were publicly available) over a period equal to the expected life of the awards.

NOTE 5 – INCOME TAXES In assessing the realizability of deferred tax asset, including the net operating loss carryforwards (NOLs), the Company assesses the available positive and negative evidence to estimate if sufficient future taxable income will be generated to utilize its existing deferred assets. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the period when those temporary difference become deductible. Based on its assessment, the Company has provided a full valuation allowance against its net deferred tax assets as their future utilization remains uncertain at this time. In 2021, the deferred tax valuation allowance increased by $1,581,507. In 2020, the deferred tax valuation allowance increased by $1,649,389. At December 31, 2021, we had approximately $89,000,000 of federal net operating tax loss carryforward which begins to expire in <span id="xdx_90D_eus-gaap--OperatingLossCarryforwardsExpirationDate_dxL_c20210101__20211231__us-gaap--IncomeTaxAuthorityAxis__us-gaap--InternalRevenueServiceIRSMember_zMKKU7HA0V4f" title="Expiration of net operating tax loss carry-forward::XDX::Dec.31%2C%202028">2028. At December 31, 2020, we had approximately $89,000,000 of federal net operating tax loss carryforward which begins to expire in 2028. In accordance with Section 382 of the Internal Revenue code, the usage of the Company’s Federal Carryforwards could be limited in the event of a change in ownership. As of December 31, 2021, the Company has not completed an analysis as to whether or not an ownership change has occurred. We are currently subject to the general three-year state of limitation for federal tax. Under this general rule, the earliest period subject to potential audit is 2018. For years to which the Company may utilize its net operating losses, the IRS has the ability to examine the tax year that generated those losses and propose adjustments up to the amount of losses utilized. The Company applies the FASB’s provisions for uncertain tax positions. The Company utilizes the two-step process to determine the amount of recognized tax benefit. For tax positions meeting the more-likely-than-not threshold, the amount recognized in the consolidated financial statements is the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement with the relevant tax authority. The Company recognizes interest and penalties associated with uncertain tax positions as a component of income tax expense. As of December 31, 2021, management does not believe the Company has any material uncertain tax positions that would require it to measure and reflect the potential lack of sustainability of a position on audit in its financial statements. The Company will continue to evaluate its uncertain tax positions in future periods to determine if measurement and recognition in its financial statements is necessary. The Company does not believe there will be any material changes in its unrecognized tax positions over the next year. “The CARES Act,” includes tax provisions relevant to businesses that will impact taxes related to 2018, 2019, and 2020. Some of the significant tax law changes are to increase the limitation on deductible business interest expenses for 2019 and 2020, allow for the five-year carryback of net operating losses for 2018-2020, suspend the <span id="xdx_902_ecustom--PercentageOfOperatingLossCarryforwardsLimitationSuspended_iI_dp_c20200327__us-gaap--IncomeTaxAuthorityAxis__us-gaap--InternalRevenueServiceIRSMember_zvSmxO79VQMb" title="Percentage of Operating Loss Carryforwards Limitation Suspended">80% limitation of taxable income for net operating, loss carryforwards for 2018-2020, provide for the acceleration of depreciation expense from 2018 and forward on qualified improvement property, and accelerate the ability to claim refunds of AMT credit carryforwards. The Company is required to recognize the effect on the consolidated financial statements in the period the law was enacted.

The PPP, established as part of the Coronavirus Aid, Relief and Economic Security Act (“CARES Act”), provides for loans to qualifying businesses for amounts up to 2.5 times of the average monthly payroll expenses of the qualifying business. The Promissory Note has a loan maturity of <span id="xdx_905_eus-gaap--DebtInstrumentMaturityDate_dd_c20200409__20200410__us-gaap--TypeOfArrangementAxis__custom--PayrollProtectionProgramMember__us-gaap--DebtInstrumentAxis__custom--PPPLoanMember_zS3Up1Yvnq5k" title="Maturity date">April 10, 2022, a stated interest rate of <span id="xdx_904_eus-gaap--DebtInstrumentInterestRateDuringPeriod_dp_uPure_c20200409__20200410__us-gaap--TypeOfArrangementAxis__custom--PayrollProtectionProgramMember__us-gaap--DebtInstrumentAxis__custom--PPPLoanMember_zW3oXaoLrpN4" title="Interest rate during period">1.0% per annum, and has payments of principal and interest that are due monthly after an initial six-month deferral period where interest accrues, but no payments are due. The Promissory Note provides for customary events of default, including, among others, those relating to failure to make payment when due and breaches of representations. The Company may prepay the principal of the Promissory Note at any time without incurring any prepayment charges. The loan is subject to all the terms and conditions applicable under the PPP and is subject to review by the Small Business Association (the “SBA”) for compliance with program requirements, including the Company’s certification that the current economic uncertainty made the PPP loan request necessary to support ongoing operations and the Company’s obtaining approval from the SBA for the private placement equity transaction. In June 2020, the Payroll Protection Program Flexibility Act (“PPPFA”) was signed into law adjusting certain key terms of loans issued under the PPP. In accordance with the PPPFA, the initial deferral period may be extended from six to up to ten months and the loan maturity may be extended from two to five years. The PPPFA also provided for certain other changes, including the extent to which the loan may be forgiven. The loan’s principal and accrued interest were forgivable to the extent that the Company initially qualified for the loan and the proceeds were used for eligible purposes, subject to certain limitations, and that the Company maintains its payroll levels over a twenty-four-week period following the loan date. As the legal form of the Promissory Note was a debt obligation, the Company accounted for it as debt under Accounting Standards Codification (ASC) 470, Debt and recorded a liability of $<span id="xdx_904_eus-gaap--LongTermDebtCurrent_iI_c20200410__us-gaap--TypeOfArrangementAxis__custom--PayrollProtectionProgramMember__us-gaap--DebtInstrumentAxis__custom--PPPLoanMember_zej8xoKZa456" title="Debt liability">781,800 in the consolidated balance sheet upon receipt of the loan proceeds. The Company applied for forgiveness, and on November 20, 2020, we received confirmation from our bank that the Promissory Note was forgiven by the SBA. The loan balance plus accrued interest of $786,889 was recorded as a gain on extinguishment of debt in the December 31, 2020, consolidated statement of operations. The SBA has created an audit safe harbor for any PPP loan borrower that, together with its affiliates, received PPP loans with an original amount of less than $2 million. The safe harbor is designed to protect a small borrower from a PPP audit based on its good faith certification. However, the government may still decide to audit a PPP loan for other purposes, such as possible misuse of PPP funds. The Company has not been notified of an audit by the SBA.

NOTE 12– LEASE Operating Lease The Company has an operating lease primarily consisting of office space with remaining lease of 18 months. On March 4, 2020, we entered into the Fourth Amendment to Commercial Lease Agreement (the “Lease Extension”), wherein we extended the Lease through August 31, 2025. The Lease Extension contains a renewal provision under which the Lease has been extended for an additional five-year period under the same terms and conditions of the original Lease Agreement. Management has identified this extension as a reassessment event, as we have elected to exercise the Lease Extension option even though the Company had previously determined that it was not reasonably certain to do so. The Company has reassessed the discount rate at the remeasurement date, at 14.8% and the Company has remeasured its ROU asset and lease liability on our balance sheet using the discount rate that applies as of the date of the reassessment event to remeasure its Operating lease asset and lease liability. The reassessment is based on the remaining lease term and lease payments. The Company has further concluded that the Lease Extension has no effects on the classification of the Lease. Rent expense for the twelve months ended December 31, 2021, and 2020 was $286,358 and $295,692, respectively. Lease Position Operating lease asset and liability for our operating lease were recorded in the consolidated balance sheet as follows: <table cellpadding="0" cellspacing="0" style="font: 10pt Arial, Helvetica, Sans-Serif;

NOTE 13– AGREEMENT WITH PDL BIOPHARMA, INC. On June 26, 2015, we entered into a Credit Agreement (as subsequently amended) with PDL BioPharma, Inc. (“PDL”), as administrative agent and lender (“the Lender”) (the “PDL Credit Agreement”). Under the PDL Credit Agreement the Lender made available to us up to $<span id="xdx_901_eus-gaap--DebtInstrumentUnusedBorrowingCapacityAmount_iI_pp0n6_c20150626__us-gaap--CreditFacilityAxis__custom--PDLBioPharmaIncMember_zEPdlJHjr5hh" title="Amount available under credit agreement">40 million in two tranches of $<span id="xdx_90F_eus-gaap--DebtInstrumentUnusedBorrowingCapacityAmount_iI_pp0n6_c20150626__us-gaap--CreditFacilityAxis__custom--PDLBioPharmaIncMember__us-gaap--LongtermDebtTypeAxis__custom--TrancheOneMember_zyK85PNIMQWb" title="Amount available under credit agreement">20 million each.

From October 8, 2015 through May 14, 2019, the outstanding borrowings under the Tranche One Loan bore interest at the rate of <span id="xdx_906_eus-gaap--DebtInstrumentInterestRateDuringPeriod_dp_c20151008__20190513__us-gaap--CreditFacilityAxis__custom--PDLBioPharmaIncMember__us-gaap--LongtermDebtTypeAxis__custom--TrancheOneMember_z6OL5JZZvxIb" title="Interest rate during period">13.5% per annum, payable quarterly.

On January 31, 2019, February 28, 2019, March 29, 2019 and April 29, 2019, the Company and Lender entered into the Tenth, Eleventh, Twelfth, and Thirteenth Amendments to the PDL Modification Agreement, as previously amended, respectively, pursuant to which the parties agreed to amend the PDL Modification Agreement to provide that (A) the dates on which the Lender may elect, in the Lender’s sole discretion, to terminate the Modification Period would be July 31, 2018 and, pursuant to the Thirteenth Amendment to the PDL Modification Agreement, May 15, 2019 (rather than January 31, February 28, June 30, and April 30, respectively) (with each such date permitted to be extended by the Lender in its sole discretion); (B) the Company could satisfy its obligations under the PDL Modification Agreement, as amended, to obtain financing by obtaining (a) at least $<span id="xdx_90B_ecustom--NetCashProceedsForIssuanceCapitalStockOrDebt_pp0p0_c20190130__20190131__us-gaap--CreditFacilityAxis__custom--TenthPDLModificationAgreementMember__us-gaap--DebtInstrumentRedemptionPeriodAxis__us-gaap--DebtInstrumentRedemptionPeriodOneMember_zUDOvmVkfnna" title="Net cash proceeds for issuance capital stock or debt">2,050,000 in net cash proceeds from the issuance of Capital Stock (other than Disqualified Capital Stock) or Debt on or prior to February 23, 2018 and (b) an additional (i) $<span id="xdx_90E_ecustom--NetCashProceedsForIssuanceCapitalStockOrDebt_pp0p0_c20180227__20180228__us-gaap--CreditFacilityAxis__custom--EleventhPDLModificationAgreementMember__us-gaap--DebtInstrumentRedemptionPeriodAxis__us-gaap--DebtInstrumentRedemptionPeriodTwoMember_zAbo0a91PLRd" title="Net cash proceeds for issuance capital stock or debt">750,000 in net cash proceeds from the issuance of Capital Stock (other than Disqualified Capital Stock) or Debt on or prior to July 13, 2018 and (ii) $<span id="xdx_902_ecustom--NetCashProceedsForIssuanceCapitalStockOrDebt_pp0p0_c20190328__20190329__us-gaap--CreditFacilityAxis__custom--TwelfthPDLModificationAgreementMember__us-gaap--DebtInstrumentRedemptionPeriodAxis__us-gaap--DebtInstrumentRedemptionPeriodThreeMember_zhBo9Fzfeuxi" title="Net cash proceeds for issuance capital stock or debt">750,000 in net cash proceeds from the issuance of Capital Stock (other than Disqualified Capital Stock) or Debt on or prior to May 15, 2019 (rather than January 31, February 28, June 30, and April 30, respectively) (resulting in aggregate net cash proceeds of at least $<span id="xdx_900_ecustom--NetCashProceedsForIssuanceCapitalStockOrDebt_pp0p0_c20190428__20190429__us-gaap--CreditFacilityAxis__custom--ThirteenPDLModificationAgreementMember__us-gaap--DebtInstrumentRedemptionPeriodAxis__us-gaap--DebtInstrumentRedemptionPeriodFourMember_z3LWolPdmaJ2" title="Net cash proceeds for issuance capital stock or debt">3,550,000); and (C) the Company’s quarterly interest payments that would otherwise have been due to Lender on December 31, 2018 and June 30, 2019 would be deferred until May 15, 2019 (the end of the extended Modification Period) and that such deferral would be a Covered Event. On April 9, 2019, the Company, PDL Investment entered into a Fourth Amendment to PDL Credit Agreement (the “Fourth Amendment to the PDL Credit Agreement”), wherein the Company executed an Amended and Restated Tranche One Term Note in the principal amount of $20,000,000 to PDL Investments (the “Amended Tranche One Loan”), pursuant to which the parties agreed, among other things, to amend the note from registered to unregistered form. On May 15, 2019, the Company, the Lender, Steven G. Johnson (our Chief Executive Officer, President, Secretary and Treasurer), individually, and Dr. James R. Higgins (a member of our board of directors), individually (Mr. Johnson and Dr. Higgins, collectively, the “Tranche Three Lenders”) entered into a Fifth Amendment to the PDL Credit Agreement (the “Fifth PDL Credit Agreement Amendment”), pursuant to which the parties agreed to amend the PDL Credit Agreement to, among other things, (i) provide for a new tranche of term loan in the aggregate principal amount of $<span id="xdx_902_eus-gaap--DebtInstrumentFaceAmount_iI_pp0p0_c20190515__us-gaap--CreditFacilityAxis__custom--FifthPDLCreditAgreementAmendmentMember__us-gaap--LongtermDebtTypeAxis__us-gaap--MediumTermNotesMember_zQQddrVMJmY4" title="Note amount">200,000, from the Tranche Three Lenders, with a maturity date of <span id="xdx_90D_eus-gaap--DebtInstrumentMaturityDate_dd_c20190514__20190515__us-gaap--CreditFacilityAxis__custom--FifthPDLCreditAgreementAmendmentMember__us-gaap--LongtermDebtTypeAxis__us-gaap--MediumTermNotesMember_zeYw416LDCia" title="Maturity date">October 7, 2020 and bearing interest at the rate of 15.5% per annum, payable quarterly in arrears (subject to the terms of the PDL Modification Agreement, as amended) (the “Tranche Three Loan”); (ii) increase the interest rate for outstanding borrowings under the Amended Tranche One Loan from <span id="xdx_903_eus-gaap--DebtInstrumentInterestRateDuringPeriod_dp_c20151008__20190513__us-gaap--CreditFacilityAxis__custom--PDLBioPharmaIncMember__us-gaap--LongtermDebtTypeAxis__custom--TrancheOneMember_zTy2wtGZKVWj" title="Interest rate during period">13.5% per annum to <span id="xdx_90C_eus-gaap--DebtInstrumentInterestRateStatedPercentage_iI_dp_c20190515__us-gaap--CreditFacilityAxis__custom--PDLBioPharmaIncMember__us-gaap--LongtermDebtTypeAxis__custom--TrancheOneMember_zGiRflh7vt7l" title="Interest rate during period">15.5% per annum, payable quarterly in arrears (subject to the terms of the PDL Modification Agreement, as amended), effective May 15, 2019,; and (iii) provide for the issuance of the Twelfth Amendment Note, pursuant to the terms of the Twelfth Amendment to the HealthCor Agreement (see NOTE 10 for details).

We had three separate issuances of equity securities convertible into common stock that qualify under this accounting treatment, (i) the 2011 HealthCor Notes, (ii) the 2012 HealthCor Notes and (iii) the 2014 HealthCor Notes. Because the conversion option and the 2011 HealthCor Warrants on the 2011 HealthCor Notes were originally classified as a liability when issued due to the down round provision and the removal of the provision requiring liability treatment, and subsequently reclassified to equity on December 31, 2011 when the 2011 HealthCor Notes were amended, only the accrued interest capitalized as payment in kind (‘‘PIK’’) since reclassification qualifies under this accounting treatment. We recorded an aggregate of $2,734,688 and $4,403,770 in interest for the years ended December 31, 2021 and 2020, respectively, related to these transactions. For the years ended December 31, 2021, and 2020, we recorded $3,002,790 and $2,743,735, respectively, of PIK related to the notes included in the HealthCor Purchase Agreement. The face amount of the 2012 HealthCor Notes, 2014 HealthCor Notes, the Fifth Amendment Notes and the Eighth Amendment Notes and all accrued PIK interest also qualify for BCF treatment as discussed above. Under the accounting standards, we determined that the restructuring of the HealthCor notes, pursuant to the terms of the Ninth Amendment, resulted in a troubled debt restructuring. As the future cash flows were greater than the carrying amount of the debt at the date of the amendment, we accounted for the change prospectively using the new effective interest rate. During the years ended December 31, 2021, and 2020, we recorded a BCF of $0 and $0, respectively. The BCF was recorded as a charge to debt discount and a credit to additional paid in capital, with the debt discount, using the effective interest method, amortized to interest expense over the term of the notes. Warrants were issued with the Fourth, Fifth, Eighth, Ninth, and Allonge 3 Amendment Notes and the proceeds were allocated to the instruments based on relative fair value as the warrants did not contain any features requiring liability treatment and therefore were classified as equity. At each amendment date, the warrants were recorded as debt discount, as a reduction of the net carrying amount of the debt. The debt discounts are amortized into interest expense each period under the effective interest method. The value allocated to the Ninth Amendment Warrants was $378,000. The value allocated to the Allonge 3 Amendment Warrants was $420,000.
