1. Description of Business Stereotaxis designs, manufactures and markets robotic systems, instruments and information systems for the interventional laboratory. Our proprietary robotic technology, Robotic Magnetic Navigation, fundamentally transforms endovascular interventions using precise computer-controlled magnetic fields to directly control the tip of flexible interventional catheters or devices. Direct control of the tip of an interventional device, in contrast to all manual hand-held devices that are controlled from their handle, can improve the precision, stability, reach and safety of these devices during procedures. Our primary clinical focus has been electrophysiology, specifically cardiac ablation procedures for the treatment of arrhythmias. Cardiac ablation has become a well-accepted therapy for arrhythmias and a multi-billion-dollar medical device market with expectations for substantial long-term growth. We have shared our aspiration and a product strategy to expand the clinical focus of our technology to several additional endovascular indications including coronary, neuro, and peripheral interventions. There is substantial real-world evidence and clinical literature for Robotic Magnetic Navigation in electrophysiology. Hundreds of electrophysiologists at over one hundred hospitals globally have treated over 100,000 arrhythmia patients with our robotic technology. Clinical use of our technology has been documented in over 400 clinical publications. Robotic Magnetic Navigation is designed to enable physicians to complete more complex interventional procedures with greater success and safety by providing image-guided delivery of catheters through the blood vessels and chambers of the heart to treatment sites. This is achieved using externally applied computer-controlled magnetic fields that govern the motion of the working tip of the catheter, resulting in improved navigation. The more flexible atraumatic design of catheters driven using magnetic fields may reduce the risk of patient harm and other adverse events. Performing the procedure from a control cockpit enables physicians to complete procedures in a safe location protected from x-ray exposure, with greater ergonomics, and improved efficiency. We believe these benefits can be applicable in other endovascular indications where navigation through complex vasculature is often challenging or unsuccessful and generates significant x-ray exposure. Our primary products include the Genesis RMN System, the Odyssey Solution, and other related devices. We also offer to our customers the Stereotaxis Imaging Model S x-ray System and other accessory devices. The Genesis RMN System is designed to enable physicians to complete more complex interventional procedures by providing image-guided delivery of catheters through the blood vessels and chambers of the heart to treatment sites. This is achieved using externally applied magnetic fields that govern the motion of the working tip of the catheter, resulting in improved navigation, efficient procedures, and reduced x-ray exposure. The Odyssey Solution consolidates lab information onto one large integrated display, enabling physicians to view and control all the key information in the operating room. This is designed to improve lab layout and procedure efficiency. The system also features a remote viewing and recording capability called Odyssey Cinema, which is an innovative solution that delivers synchronized content for optimized workflow, advanced care, and improved productivity. This tool includes an archiving capability that allows clinicians to store and replay entire procedures or segments of procedures. This information can be accessed from locations throughout the hospital local area network and over the global Odyssey Network providing physicians with a tool for clinical collaboration, remote consultation, and training. The Stereotaxis Imaging Model S provides an integrated complete solution for a robotic interventional operating room. It is a single-plane, full-power x-ray system and includes the c-arm, powered table, motorized boom, and large high-definition monitors. Stereotaxis Imaging Model S incorporates modern fluoroscopy technology to support high quality imaging while minimizing radiation exposure for patients and physicians. The combination of RMN Systems with Stereotaxis Imaging Model S is designed to reduce the cost of acquisition, the ongoing cost of ownership, and the complexity of installation of a robotic electrophysiology practice. We promote our full suite of products in a typical hospital implementation, subject to regulatory approvals or clearances. This implementation requires a hospital to agree to an upfront capital payment and recurring payments. The upfront capital payment typically includes equipment and installation charges. The recurring payments typically include disposable costs for each procedure, equipment service costs beyond warranty period, and ongoing software updates. In hospitals where our full suite of products has not been implemented, equipment upgrade or expansion can be implemented upon purchasing of the necessary upgrade or expansion. We have received regulatory clearances and registration necessary for us to market the Genesis RMN System in the U.S. and Europe, and we are in the process of obtaining necessary registrations for extending our markets in other countries. Our prior generation robotic magnetic navigation system, the Niobe System, and the Odyssey Solution, Cardiodrive, and various disposable interventional devices have received regulatory clearance in the U.S., Europe, Canada, China, Japan and various other countries. We have received the regulatory clearance, licensing and/or CE Mark approvals that allow us to market the Vdrive and Vdrive Duo Systems with the V-CAS, V-Loop and V-Sono devices in the U.S., Canada and Europe. The Stereotaxis Imaging Model S x-ray System is CE marked and cleared by the FDA. We have strategic relationships with technology leaders and innovators in the global interventional market. Through these strategic relationships we provide compatibility between our robotic magnetic navigation system and digital imaging and 3D catheter location sensing technology, as well as disposable interventional devices. The maintenance of these strategic relationships, or the establishment of equivalent alternatives, is critical to our commercialization efforts. There are no guarantees that any existing strategic relationships will continue, and efforts are ongoing to ensure the availability of integrated systems and devices and/or equivalent alternatives. We cannot provide assurance as to the timeline of the ongoing availability of such compatible systems or our ability to obtain equivalent alternatives on competitive terms or at all.

2. Summary of Significant Accounting Policies Basis of Presentation The accompanying Financial Statements have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”). Cash and Cash Equivalents Cash and cash equivalents include cash on hand, money market instruments, and other highly liquid investments with original maturities of three months or less from the date of purchase. <p id="xdx_84D_eus-gaap--CashAndCashEquivalentsRestrictedCashAndCashEquivalentsPolicy_zc9jRTH015gk" style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in; background-color: white">Restricted Cash Restricted cash primarily consists of cash that the Company is obligated to maintain in accordance with contractual obligations. Investments Our investments may include, at any time, a diversified portfolio of cash equivalents and short- and long-term investments in a variety of high-quality securities, including money market funds, U.S. treasury and U.S. government agency securities, corporate notes and bonds, commercial paper, non-U.S. government agency securities, and municipal notes. As of December 31, 2022, the Company’s short-term investments consisted of U.S. treasury securities and fixed maturity, marketable debt securities with original maturities at the time of purchase of one year or less, but greater than 90 days. These investments are classified as held to maturity. Securities classified as held to maturity are securities that the Company has the ability and intent to hold to maturity or redemption and are carried at amortized cost. Amortized cost of U.S. treasury securities and marketable debt securities are based on the Company’s purchase price adjusted for accrual of discount, or amortization of premium, and recognition of impairment charges, if any. The amortized cost of securities the Company purchases at a discount or premium will equal the face or par value at maturity or the call date, if applicable. Interest is reported as income when earned and is adjusted for amortization or accretion of any premium or discount. There were no impairments for the year ended December 31, 2022. Fair Value Measurements Financial instruments consist of cash and cash equivalents, restricted cash, investments, accounts receivable, and accounts payable. The Company measures certain financial assets and liabilities at fair value on a recurring basis. General accounting principles for fair value measurement establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets and liabilities (“Level 1”) and the lowest priority to unobservable inputs (“Level 3”). The three levels of the fair value hierarchy are described below: <table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; background-color: white; border-collapse: collapse"> <tr style="font: 10pt Times New Roman, Times, Serif"> <td style="font: 10pt Times New Roman, Times, Serif; vertical-align: top; width: 0.5in; text-align: justify">Level 1:</td> <td style="font: 10pt Times New Roman, Times, Serif; vertical-align: bottom; width: 0.1in; text-align: justify"> </td> <td style="font: 10pt Times New Roman, Times, Serif; vertical-align: bottom; text-align: justify">Values are based on unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.</td></tr> <tr style="font: 10pt Times New Roman, Times, Serif"> <td style="font: 10pt Times New Roman, Times, Serif; vertical-align: top; text-align: justify"> </td> <td style="font: 10pt Times New Roman, Times, Serif; vertical-align: bottom; text-align: justify"> </td> <td style="font: 10pt Times New Roman, Times, Serif; vertical-align: bottom; text-align: justify"> </td></tr> <tr style="font: 10pt Times New Roman, Times, Serif"> <td style="font: 10pt Times New Roman, Times, Serif; vertical-align: top; text-align: justify">Level 2:</td> <td style="font: 10pt Times New Roman, Times, Serif; vertical-align: bottom; text-align: justify"> </td> <td style="font: 10pt Times New Roman, Times, Serif; vertical-align: bottom; text-align: justify">Values are based on quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, or other model-based valuation techniques for which all significant assumptions are observable in the market.</td></tr> <tr style="font: 10pt Times New Roman, Times, Serif"> <td style="font: 10pt Times New Roman, Times, Serif; vertical-align: top; text-align: justify"> </td> <td style="font: 10pt Times New Roman, Times, Serif; vertical-align: bottom; text-align: justify"> </td> <td style="font: 10pt Times New Roman, Times, Serif; vertical-align: bottom; text-align: justify"> </td></tr> <tr style="font: 10pt Times New Roman, Times, Serif"> <td style="font: 10pt Times New Roman, Times, Serif; vertical-align: top; text-align: justify">Level 3:</td> <td style="font: 10pt Times New Roman, Times, Serif; vertical-align: bottom; text-align: justify"> </td> <td style="font: 10pt Times New Roman, Times, Serif; vertical-align: bottom">Values are generated from model-based techniques that use significant assumptions not observable in the market. </td></tr> </table> As of December 31, 2022, financial assets that are classified as Level 2 include money market funds, U.S. treasury securities and corporate debt securities. As of December 31, 2021, financial assets that are classified as Level 2 include money market funds. The Company reviews trading activity and pricing for these investments as of the measurement date. When sufficient quoted pricing for identical securities is not available, the Company uses market pricing and other observable market inputs for similar securities. These inputs either represent quoted prices for similar assets in active markets or have been derived from observable market data. This approach results in the Level 2 classification of these securities within the fair value hierarchy. Compensating Cash Arrangement In July 2020, the Company entered into a letter of credit to support a commitment of less than $<span id="xdx_90B_eus-gaap--LinesOfCreditCurrent_iI_pn5n6_do_c20200731__us-gaap--CreditFacilityAxis__us-gaap--LetterOfCreditMember__srt--RangeAxis__srt--MaximumMember_zIR94sNK53qi" title="Line of credit, current">0.3 million. As a condition of the letter of credit, the Company was required to maintain a $0.3 million compensating balance until the expiration of the letter of credit. The letter of credit expired in the fourth quarter of 2021. Accounts Receivable and Allowance for Uncollectible Accounts Accounts receivable primarily include amounts due from hospitals and distributors for acquisition of magnetic systems, associated disposable device sales and service contracts. Credit is granted on a limited basis, with balances due generally within 30 days of billing. The provision for bad debts is based upon management’s assessment of historical and expected net collections considering business and economic conditions and other collection indicators. Inventory The Company values its inventory at the lower of cost, as determined using the first-in, first-out (FIFO) method, or net realizable value. The Company periodically reviews its physical inventory and provides a reserve upon identification of potential excess or obsolete items. Excess manufacturing overhead costs attributable to idle facility expenses or abnormally low production volumes are excluded from inventory and recorded as an expense in the period incurred. Property and Equipment Property and equipment consist primarily of leasehold improvements, construction in process, computer, office, research and demonstration equipment, and equipment held for lease and are stated at cost. Depreciation is calculated using the straight-line method over the estimated useful lives or life of the base lease term, ranging from three to ten years. Long-Lived Assets If facts and circumstances suggest that a long-lived asset may be impaired, the carrying value is reviewed. If this review indicates that the carrying value of the asset will not be recovered, as determined based on projected undiscounted cash flows related to the asset over its remaining life, the carrying value of the asset is reduced to its estimated fair value, which in most cases is estimated based upon Level 3 inputs. Intangible Assets Intangible assets consist of purchased technology and intellectual property rights valued at cost on the acquisition date and amortized over their estimated useful lives of 10-15 years. If facts and circumstances suggest that an intangible asset may be impaired, the carrying value is reviewed. If this review indicates that the carrying value of the asset will not be recovered, as determined based on projected undiscounted cash flows related to the asset over its remaining life, the carrying value of the asset is reduced to its estimated fair value, which in most cases is estimated based upon Level 3 inputs. Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of income and loss during the reporting period. Actual results could differ from those estimates. Revenue and Costs of Revenue Revenue Recognition The Company accounts for revenue in accordance with Accounting Standards Codification Topic 606 (“ASC 606”), Revenue from Contracts with Customers. We generate revenue from initial capital sales of systems as well as recurring revenue from the sale of our proprietary disposable devices, from royalties paid to the Company on the sale of various devices as provided by co-development and co-placement arrangements, and from revenue including ongoing software updates and service contracts. We account for a contract with a customer when there is a legally enforceable contract between the Company and the customer, the rights of the parties are identified, the contract has commercial substance, and collectability of the contract consideration is probable. We record our revenue based on consideration specified in the contract with each customer, net of any taxes collected from customers that are remitted to government authorities. For contracts containing multiple products and services the Company accounts for individual products and services as separate performance obligations if they are distinct, which is if a product or service is separately identifiable from other items in the bundled package, and if a customer can benefit from it on its own or with other resources that are readily available to the customer. The Company recognizes revenues as the performance obligations are satisfied by transferring control of the product or service to a customer. For arrangements with multiple performance obligations, revenue is allocated to each performance obligation based on its relative standalone selling price. Standalone selling prices are based on observable prices at which the Company separately sells the products or services. If a standalone selling price is not directly observable, then the Company estimates the standalone selling price considering market conditions and entity-specific factors including, but not limited to, features and functionality of the products and services and market conditions. The Company regularly reviews standalone selling prices and updates these estimates if necessary. Our revenue recognition policy affects the following revenue streams in our business as follows: <table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; border-collapse: collapse"> <tr style="font: 10pt Times New Roman, Times, Serif; vertical-align: top"> <td style="font: 10pt Times New Roman, Times, Serif; width: 0.3in"> </td> <td style="font: 10pt Times New Roman, Times, Serif">Systems:</td></tr> <tr style="font: 10pt Times New Roman, Times, Serif; vertical-align: top"> <td style="font: 10pt Times New Roman, Times, Serif"> </td> <td style="font: 10pt Times New Roman, Times, Serif"> </td></tr> <tr style="font: 10pt Times New Roman, Times, Serif; vertical-align: top"> <td style="font: 10pt Times New Roman, Times, Serif; text-align: justify"> </td> <td style="font: 10pt Times New Roman, Times, Serif; text-align: justify">Contracts related to the sale of systems typically contain separate obligations for the delivery of system(s), installation and an implied obligation to provide software enhancements if and when available for one year following installation. Revenue is recognized when the Company transfers control to the customer, which is generally at the point when acceptance occurs that indicates customer acknowledgment of delivery or installation, depending on the terms of the arrangement. Revenue from the implied obligation to deliver software enhancements if and when available is recognized ratably over the first year following installation of the system as the customer receives the right to software updates throughout the period and is included in Other Recurring Revenue. The Company’s system contracts generally do not provide a right of return. Systems are generally covered by a one-year assurance type warranty; warranty costs were approximately $0.1 million and $0.2 million for the years ended December 31, 2022 and 2021, respectively.

Contract assets primarily represent the difference between the revenue that was earned but not billed on service contracts and revenue from system contracts that was recognized based on the relative selling price of the related performance obligations and the contractual billing terms in the arrangements. Customer deposits primarily relate to future system sales but can also include deposits on disposable sales. Deferred revenue is primarily related to service contracts, for which the service fees are billed up-front, generally quarterly or annually, and for amounts billed in advance for system contracts for which some performance obligations remain outstanding. For service contracts, the associated deferred revenue is generally recognized ratably over the service period. For system contracts, the associated deferred revenue is recognized when the remaining performance obligations are satisfied. The Company did not have any impairment losses on its contract assets for the periods presented. Revenue recognized for the years ended December 31, 2022 and 2021, that was included in the deferred revenue balance at the beginning of each reporting period was $5.9 million and $5.1 million, respectively. The Company has determined that sales incentive programs for the Company’s sales team meet the requirements to be capitalized as the Company expects to generate future economic benefits from the related revenue generating contracts after the initial capital sales transaction. The costs capitalized as contract acquisition costs included in prepaid expenses and other assets in the Company’s balance sheets were $0.2 million as of December 31, 2022 and 2021. The Company did not incur any impairment losses during any of the periods presented. Costs of systems revenue include direct product costs, installation labor and other costs, estimated warranty costs, and initial training and product maintenance costs. These costs are recorded at the time of sale. Costs of disposable revenue include direct product costs and estimated warranty costs and are recorded at the time of sale. Cost of revenue from services and license fees are recorded when incurred. Leasing Arrangements A lease is defined as a contract, or part of a contract, that conveys the right to control the use of identified property, plant or equipment for a period of time in exchange for consideration. The Company accounts for leases in accordance with Accounting Standards Update No. 2016-02 “Leases” (Topic 842) and all subsequent ASUs that modified Topic 842 (“ASC 842”). The Company determines if an arrangement contains a lease at inception. The Company leases its facilities under operating leases. In accordance with ASC 842, operating lease agreements are recognized on the balance sheet as a right-of-use (“ROU”) asset and a corresponding lease liability. These leases generally do not have significant rent escalation holidays, concessions, leasehold improvement incentives, or other build-out clauses. Further, the leases do not contain contingent rent provisions. Many of our leases include both lease (i.e., fixed payments including rent, taxes, and insurance costs) and non-lease components (i.e., common-area or other maintenance costs) which are accounted for as a single lease component as we have elected the practical expedient to group lease and non-lease components for all leases. A portion of our prior principal executive office was subleased to a third party through 2021. The sublease did not have significant rent escalation holidays, concessions, leasehold improvement incentives, or other build-out clauses. In addition, the sublease did not contain contingent rent provisions nor were there options to extend or terminate the sublease. The sublease ended December 31, 2021. The Company’s lease agreements often include one or more options to renew at the Company’s discretion. If at lease inception, the Company considers the exercising of a renewal option to be reasonably certain, the Company will include the extended term in the calculation of the ROU asset and lease liability. The Company elected not to include short-term leases (i.e., leases with initial terms of twelve months or less) on the balance sheet. The calculated amounts of the ROU assets and lease liabilities are impacted by the length of the lease term and the discount rate used to calculate the present value of the minimum lease payments. ASC 842 requires the use of the discount rate implicit in the lease whenever this rate is readily determinable. As this rate is rarely determinable, the Company utilizes its incremental borrowing rate at lease inception. Research and Development Costs Internal research and development costs are expensed in the period incurred. Amounts receivable from strategic relationships under research reimbursement agreements are recorded as a contra-research and development expense in the period reimbursable costs are incurred. There were no material receivables as of December 31, 2022 or 2021 under these types of agreements. Advance receipts or other unearned reimbursements are included in accrued liabilities on the accompanying balance sheet until earned. Stock-Based Compensation The Company accounts for its grants of stock options, stock appreciation rights, restricted shares, and restricted stock units and for its employee stock purchase plan in accordance with the provisions of general accounting principles for share-based payments. These accounting principles require the determination of the fair value of the stock-based compensation at the grant date and the recognition of the related expense over the period in which the stock-based compensation vests. For time-based awards, the Company utilizes the Black-Scholes valuation model to determine the fair value of stock options and stock appreciation rights at the date of grant. The weighted average assumptions and fair value for options granted during the year ended December 31, 2022, were 1) expected dividend rate of 0%; 2) expected volatility of 80% based on the Company’s historical volatility; 3) risk-free interest rate based on the Treasury yield on the date of grant; and 4) expected term of 6.25 years. The resulting compensation expense is recognized over the requisite service period, which is generally four years. Restricted shares and units granted to employees are valued at the fair market value at the date of grant. The Company amortizes the fair market value to expense over the service period. If the shares are subject to performance objectives, the resulting compensation expense is amortized over the anticipated vesting period and is subject to adjustment based on the actual achievement of objectives. For market-based awards, stock-based compensation expense is recognized over the minimum service period regardless of whether or not the market target is probable of being achieved. The fair value of such awards is estimated on the grant date using Monte Carlo simulations. Shares purchased by employees under the 2022 Employee Stock Purchase Plan are considered to be non-compensatory. Net Loss per Common Share Basic earnings (loss) per common share is computed by dividing the net earnings (loss) for the period by the weighted average number of common shares outstanding during the period. In periods where there is net income, we apply the two-class method to calculate basic and diluted net income (loss) per share of common stock, as our convertible preferred stock is a participating security. The two-class method is an earnings allocation formula that treats a participating security as having rights to earnings that otherwise would have been available to common stockholders. In periods where there is a net loss, the two-class method of computing earnings per share does not apply as our convertible preferred stock does not contractually participate in our losses. We compute diluted net income (loss) per common share using net income (loss) as the “control number” in determining whether potential common shares are dilutive, after giving consideration to all potentially dilutive common shares, including stock options, unvested restricted stock units outstanding during the period and potential issuance of stock upon the conversion of our convertible preferred stock issued and outstanding during the period, except where the effect of such securities would be antidilutive. The Company did not include any portion of unearned restricted shares, outstanding options, stock appreciation rights, or convertible preferred stock in the calculation of diluted loss per common share because all such securities are anti-dilutive for all periods presented. The application of the two-class method of computing earnings per share under general accounting principles for participating securities is not applicable during these periods because those securities do not contractually participate in its losses. As of December 31, 2022, the Company had <span id="xdx_90E_eus-gaap--AntidilutiveSecuritiesExcludedFromComputationOfEarningsPerShareAmount_pid_c20220101__20221231__us-gaap--AwardTypeAxis__custom--StockOptionsandStockAppreciationRightsMember_ziv9t4ZoeKjk" title="Potential common shares excluded from diluted earnings per share">3,208,065 shares of common stock issuable upon the exercise of outstanding options and stock appreciation rights at a weighted average exercise price of $<span id="xdx_90A_eus-gaap--ShareBasedCompensationArrangementByShareBasedPaymentAwardOptionsOutstandingWeightedAverageExercisePrice_iI_pid_c20221231__us-gaap--AwardTypeAxis__custom--StockOptionsandStockAppreciationRightsMember_zxRC7oMeqddk" title="Weighted average exercise price">4.21 per share, <span id="xdx_90B_eus-gaap--AntidilutiveSecuritiesExcludedFromComputationOfEarningsPerShareAmount_pid_c20220101__20221231__us-gaap--StatementEquityComponentsAxis__custom--SeriesAConvertiblePreferredStockMember_zXw7y8udc5n5" title="Potential common shares excluded from diluted earnings per share">47,364,216 shares of our common stock issuable upon conversion of our Series A Convertible Preferred Stock, <span id="xdx_906_eus-gaap--AntidilutiveSecuritiesExcludedFromComputationOfEarningsPerShareAmount_pid_c20220101__20221231__us-gaap--StatementClassOfStockAxis__custom--SeriesBConvertiblePreferredStockMember_zsvtF6sms6ji" title="Potential common shares excluded from diluted earnings per share">5,610,121 shares of our common stock issuable upon conversion of our Series B Convertible Preferred Stock and <span id="xdx_908_eus-gaap--ShareBasedCompensationArrangementByShareBasedPaymentAwardEquityInstrumentsOtherThanOptionsNonvestedNumber_iI_pid_c20221231__us-gaap--AwardTypeAxis__us-gaap--RestrictedStockMember_zmmkDWsU5WD6" title="Number of unvested restricted share units">1,208,739 shares of unvested restricted share units. The Company had no unearned restricted shares outstanding for the period ended December 31, 2022. Income Taxes In accordance with general accounting principles for income taxes, a deferred income tax asset or liability is determined based on the difference between the financial statement and tax basis of assets and liabilities as measured by the enacted tax rates that will be in effect when these differences reverse. The Company provides a valuation allowance against net deferred income tax assets unless, based upon available evidence, it is more likely than not the deferred income tax assets will be realized. Product Warranty Provisions The Company’s standard policy is to warrant all systems against defects in material or workmanship for one year following installation. The Company’s estimate of costs to service the warranty obligations is based on historical experience and current product performance trends. A regular review of warranty obligations is performed to determine the adequacy of the reserve and adjustments are made to the estimated warranty liability (included in other accrued liabilities) as appropriate. Patent Costs Costs related to filing and pursuing patent applications are expensed as incurred, as recoverability of such expenditures is uncertain. Concentrations of Risk The majority of the Company’s cash, cash equivalents and investments are deposited with one major financial institution in the U.S. Deposits in this institution exceed the amount of government provided insurance on such deposits. No single customer accounted for more than 10% of total revenue for the years ended December 31, 2022 and 2021.

Recently Issued Accounting Pronouncements In June 2016, the FASB issued ASU 2016-13, “Financial Instruments-Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments” and also issued subsequent amendments to the initial guidance under ASU 2018-19, ASU 2019-04 and ASU 2019-05. The standard modifies the measurement approach for credit losses on financial instruments, including trade receivables, from an incurred loss method to a current expected credit loss method, otherwise known as “CECL.” The standard requires the measurement of expected credit losses to be based on relevant information, including historical experience, current conditions and a forecast that is supportable. The standard is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years; early adoption is permitted. The standard must be adopted by applying a cumulative adjustment to retained earnings. The Company anticipates adopting the standard in the first quarter of 2023, although it does not expect a significant impact to the Company’s financial results.

Basis of Presentation The accompanying Financial Statements have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”).

Cash and Cash Equivalents Cash and cash equivalents include cash on hand, money market instruments, and other highly liquid investments with original maturities of three months or less from the date of purchase.

<p id="xdx_84D_eus-gaap--CashAndCashEquivalentsRestrictedCashAndCashEquivalentsPolicy_zc9jRTH015gk" style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in; background-color: white">Restricted Cash Restricted cash primarily consists of cash that the Company is obligated to maintain in accordance with contractual obligations.

Investments Our investments may include, at any time, a diversified portfolio of cash equivalents and short- and long-term investments in a variety of high-quality securities, including money market funds, U.S. treasury and U.S. government agency securities, corporate notes and bonds, commercial paper, non-U.S. government agency securities, and municipal notes. As of December 31, 2022, the Company’s short-term investments consisted of U.S. treasury securities and fixed maturity, marketable debt securities with original maturities at the time of purchase of one year or less, but greater than 90 days. These investments are classified as held to maturity. Securities classified as held to maturity are securities that the Company has the ability and intent to hold to maturity or redemption and are carried at amortized cost. Amortized cost of U.S. treasury securities and marketable debt securities are based on the Company’s purchase price adjusted for accrual of discount, or amortization of premium, and recognition of impairment charges, if any. The amortized cost of securities the Company purchases at a discount or premium will equal the face or par value at maturity or the call date, if applicable. Interest is reported as income when earned and is adjusted for amortization or accretion of any premium or discount. There were no impairments for the year ended December 31, 2022.

Fair Value Measurements Financial instruments consist of cash and cash equivalents, restricted cash, investments, accounts receivable, and accounts payable. The Company measures certain financial assets and liabilities at fair value on a recurring basis. General accounting principles for fair value measurement establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets and liabilities (“Level 1”) and the lowest priority to unobservable inputs (“Level 3”). The three levels of the fair value hierarchy are described below: <table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; background-color: white; border-collapse: collapse"> <tr style="font: 10pt Times New Roman, Times, Serif"> <td style="font: 10pt Times New Roman, Times, Serif; vertical-align: top; width: 0.5in; text-align: justify">Level 1:</td> <td style="font: 10pt Times New Roman, Times, Serif; vertical-align: bottom; width: 0.1in; text-align: justify"> </td> <td style="font: 10pt Times New Roman, Times, Serif; vertical-align: bottom; text-align: justify">Values are based on unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.</td></tr> <tr style="font: 10pt Times New Roman, Times, Serif"> <td style="font: 10pt Times New Roman, Times, Serif; vertical-align: top; text-align: justify"> </td> <td style="font: 10pt Times New Roman, Times, Serif; vertical-align: bottom; text-align: justify"> </td> <td style="font: 10pt Times New Roman, Times, Serif; vertical-align: bottom; text-align: justify"> </td></tr> <tr style="font: 10pt Times New Roman, Times, Serif"> <td style="font: 10pt Times New Roman, Times, Serif; vertical-align: top; text-align: justify">Level 2:</td> <td style="font: 10pt Times New Roman, Times, Serif; vertical-align: bottom; text-align: justify"> </td> <td style="font: 10pt Times New Roman, Times, Serif; vertical-align: bottom; text-align: justify">Values are based on quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, or other model-based valuation techniques for which all significant assumptions are observable in the market.</td></tr> <tr style="font: 10pt Times New Roman, Times, Serif"> <td style="font: 10pt Times New Roman, Times, Serif; vertical-align: top; text-align: justify"> </td> <td style="font: 10pt Times New Roman, Times, Serif; vertical-align: bottom; text-align: justify"> </td> <td style="font: 10pt Times New Roman, Times, Serif; vertical-align: bottom; text-align: justify"> </td></tr> <tr style="font: 10pt Times New Roman, Times, Serif"> <td style="font: 10pt Times New Roman, Times, Serif; vertical-align: top; text-align: justify">Level 3:</td> <td style="font: 10pt Times New Roman, Times, Serif; vertical-align: bottom; text-align: justify"> </td> <td style="font: 10pt Times New Roman, Times, Serif; vertical-align: bottom">Values are generated from model-based techniques that use significant assumptions not observable in the market. </td></tr> </table> As of December 31, 2022, financial assets that are classified as Level 2 include money market funds, U.S. treasury securities and corporate debt securities. As of December 31, 2021, financial assets that are classified as Level 2 include money market funds. The Company reviews trading activity and pricing for these investments as of the measurement date. When sufficient quoted pricing for identical securities is not available, the Company uses market pricing and other observable market inputs for similar securities. These inputs either represent quoted prices for similar assets in active markets or have been derived from observable market data. This approach results in the Level 2 classification of these securities within the fair value hierarchy.

Compensating Cash Arrangement In July 2020, the Company entered into a letter of credit to support a commitment of less than $<span id="xdx_90B_eus-gaap--LinesOfCreditCurrent_iI_pn5n6_do_c20200731__us-gaap--CreditFacilityAxis__us-gaap--LetterOfCreditMember__srt--RangeAxis__srt--MaximumMember_zIR94sNK53qi" title="Line of credit, current">0.3 million. As a condition of the letter of credit, the Company was required to maintain a $0.3 million compensating balance until the expiration of the letter of credit. The letter of credit expired in the fourth quarter of 2021.

Accounts Receivable and Allowance for Uncollectible Accounts Accounts receivable primarily include amounts due from hospitals and distributors for acquisition of magnetic systems, associated disposable device sales and service contracts. Credit is granted on a limited basis, with balances due generally within 30 days of billing. The provision for bad debts is based upon management’s assessment of historical and expected net collections considering business and economic conditions and other collection indicators.

Inventory The Company values its inventory at the lower of cost, as determined using the first-in, first-out (FIFO) method, or net realizable value. The Company periodically reviews its physical inventory and provides a reserve upon identification of potential excess or obsolete items. Excess manufacturing overhead costs attributable to idle facility expenses or abnormally low production volumes are excluded from inventory and recorded as an expense in the period incurred.

Property and Equipment Property and equipment consist primarily of leasehold improvements, construction in process, computer, office, research and demonstration equipment, and equipment held for lease and are stated at cost. Depreciation is calculated using the straight-line method over the estimated useful lives or life of the base lease term, ranging from three to ten years.

Long-Lived Assets If facts and circumstances suggest that a long-lived asset may be impaired, the carrying value is reviewed. If this review indicates that the carrying value of the asset will not be recovered, as determined based on projected undiscounted cash flows related to the asset over its remaining life, the carrying value of the asset is reduced to its estimated fair value, which in most cases is estimated based upon Level 3 inputs.

Intangible Assets Intangible assets consist of purchased technology and intellectual property rights valued at cost on the acquisition date and amortized over their estimated useful lives of 10-15 years. If facts and circumstances suggest that an intangible asset may be impaired, the carrying value is reviewed. If this review indicates that the carrying value of the asset will not be recovered, as determined based on projected undiscounted cash flows related to the asset over its remaining life, the carrying value of the asset is reduced to its estimated fair value, which in most cases is estimated based upon Level 3 inputs.

Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of income and loss during the reporting period. Actual results could differ from those estimates.

Revenue and Costs of Revenue Revenue Recognition The Company accounts for revenue in accordance with Accounting Standards Codification Topic 606 (“ASC 606”), Revenue from Contracts with Customers. We generate revenue from initial capital sales of systems as well as recurring revenue from the sale of our proprietary disposable devices, from royalties paid to the Company on the sale of various devices as provided by co-development and co-placement arrangements, and from revenue including ongoing software updates and service contracts. We account for a contract with a customer when there is a legally enforceable contract between the Company and the customer, the rights of the parties are identified, the contract has commercial substance, and collectability of the contract consideration is probable. We record our revenue based on consideration specified in the contract with each customer, net of any taxes collected from customers that are remitted to government authorities. For contracts containing multiple products and services the Company accounts for individual products and services as separate performance obligations if they are distinct, which is if a product or service is separately identifiable from other items in the bundled package, and if a customer can benefit from it on its own or with other resources that are readily available to the customer. The Company recognizes revenues as the performance obligations are satisfied by transferring control of the product or service to a customer. For arrangements with multiple performance obligations, revenue is allocated to each performance obligation based on its relative standalone selling price. Standalone selling prices are based on observable prices at which the Company separately sells the products or services. If a standalone selling price is not directly observable, then the Company estimates the standalone selling price considering market conditions and entity-specific factors including, but not limited to, features and functionality of the products and services and market conditions. The Company regularly reviews standalone selling prices and updates these estimates if necessary. Our revenue recognition policy affects the following revenue streams in our business as follows: <table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; border-collapse: collapse"> <tr style="font: 10pt Times New Roman, Times, Serif; vertical-align: top"> <td style="font: 10pt Times New Roman, Times, Serif; width: 0.3in"> </td> <td style="font: 10pt Times New Roman, Times, Serif">Systems:</td></tr> <tr style="font: 10pt Times New Roman, Times, Serif; vertical-align: top"> <td style="font: 10pt Times New Roman, Times, Serif"> </td> <td style="font: 10pt Times New Roman, Times, Serif"> </td></tr> <tr style="font: 10pt Times New Roman, Times, Serif; vertical-align: top"> <td style="font: 10pt Times New Roman, Times, Serif; text-align: justify"> </td> <td style="font: 10pt Times New Roman, Times, Serif; text-align: justify">Contracts related to the sale of systems typically contain separate obligations for the delivery of system(s), installation and an implied obligation to provide software enhancements if and when available for one year following installation.

Revenue from the implied obligation to deliver software enhancements if and when available is recognized ratably over the first year following installation of the system as the customer receives the right to software updates throughout the period and is included in Other Recurring Revenue. The Company’s system contracts generally do not provide a right of return.

Contract assets primarily represent the difference between the revenue that was earned but not billed on service contracts and revenue from system contracts that was recognized based on the relative selling price of the related performance obligations and the contractual billing terms in the arrangements. Customer deposits primarily relate to future system sales but can also include deposits on disposable sales. Deferred revenue is primarily related to service contracts, for which the service fees are billed up-front, generally quarterly or annually, and for amounts billed in advance for system contracts for which some performance obligations remain outstanding. For service contracts, the associated deferred revenue is generally recognized ratably over the service period. For system contracts, the associated deferred revenue is recognized when the remaining performance obligations are satisfied. The Company did not have any impairment losses on its contract assets for the periods presented. Revenue recognized for the years ended December 31, 2022 and 2021, that was included in the deferred revenue balance at the beginning of each reporting period was $5.9 million and $5.1 million, respectively. The Company has determined that sales incentive programs for the Company’s sales team meet the requirements to be capitalized as the Company expects to generate future economic benefits from the related revenue generating contracts after the initial capital sales transaction. The costs capitalized as contract acquisition costs included in prepaid expenses and other assets in the Company’s balance sheets were $0.2 million as of December 31, 2022 and 2021. The Company did not incur any impairment losses during any of the periods presented. Costs of systems revenue include direct product costs, installation labor and other costs, estimated warranty costs, and initial training and product maintenance costs. These costs are recorded at the time of sale. Costs of disposable revenue include direct product costs and estimated warranty costs and are recorded at the time of sale. Cost of revenue from services and license fees are recorded when incurred.

Leasing Arrangements A lease is defined as a contract, or part of a contract, that conveys the right to control the use of identified property, plant or equipment for a period of time in exchange for consideration. The Company accounts for leases in accordance with Accounting Standards Update No. 2016-02 “Leases” (Topic 842) and all subsequent ASUs that modified Topic 842 (“ASC 842”). The Company determines if an arrangement contains a lease at inception. The Company leases its facilities under operating leases. In accordance with ASC 842, operating lease agreements are recognized on the balance sheet as a right-of-use (“ROU”) asset and a corresponding lease liability. These leases generally do not have significant rent escalation holidays, concessions, leasehold improvement incentives, or other build-out clauses. Further, the leases do not contain contingent rent provisions. Many of our leases include both lease (i.e., fixed payments including rent, taxes, and insurance costs) and non-lease components (i.e., common-area or other maintenance costs) which are accounted for as a single lease component as we have elected the practical expedient to group lease and non-lease components for all leases. A portion of our prior principal executive office was subleased to a third party through 2021. The sublease did not have significant rent escalation holidays, concessions, leasehold improvement incentives, or other build-out clauses. In addition, the sublease did not contain contingent rent provisions nor were there options to extend or terminate the sublease. The sublease ended December 31, 2021. The Company’s lease agreements often include one or more options to renew at the Company’s discretion. If at lease inception, the Company considers the exercising of a renewal option to be reasonably certain, the Company will include the extended term in the calculation of the ROU asset and lease liability. The Company elected not to include short-term leases (i.e., leases with initial terms of twelve months or less) on the balance sheet. The calculated amounts of the ROU assets and lease liabilities are impacted by the length of the lease term and the discount rate used to calculate the present value of the minimum lease payments. ASC 842 requires the use of the discount rate implicit in the lease whenever this rate is readily determinable. As this rate is rarely determinable, the Company utilizes its incremental borrowing rate at lease inception.

Research and Development Costs Internal research and development costs are expensed in the period incurred. Amounts receivable from strategic relationships under research reimbursement agreements are recorded as a contra-research and development expense in the period reimbursable costs are incurred. There were no material receivables as of December 31, 2022 or 2021 under these types of agreements. Advance receipts or other unearned reimbursements are included in accrued liabilities on the accompanying balance sheet until earned.

Stock-Based Compensation The Company accounts for its grants of stock options, stock appreciation rights, restricted shares, and restricted stock units and for its employee stock purchase plan in accordance with the provisions of general accounting principles for share-based payments. These accounting principles require the determination of the fair value of the stock-based compensation at the grant date and the recognition of the related expense over the period in which the stock-based compensation vests. For time-based awards, the Company utilizes the Black-Scholes valuation model to determine the fair value of stock options and stock appreciation rights at the date of grant. The weighted average assumptions and fair value for options granted during the year ended December 31, 2022, were 1) expected dividend rate of 0%; 2) expected volatility of 80% based on the Company’s historical volatility; 3) risk-free interest rate based on the Treasury yield on the date of grant; and 4) expected term of 6.25 years. The resulting compensation expense is recognized over the requisite service period, which is generally four years. Restricted shares and units granted to employees are valued at the fair market value at the date of grant. The Company amortizes the fair market value to expense over the service period. If the shares are subject to performance objectives, the resulting compensation expense is amortized over the anticipated vesting period and is subject to adjustment based on the actual achievement of objectives. For market-based awards, stock-based compensation expense is recognized over the minimum service period regardless of whether or not the market target is probable of being achieved. The fair value of such awards is estimated on the grant date using Monte Carlo simulations. Shares purchased by employees under the 2022 Employee Stock Purchase Plan are considered to be non-compensatory.

Net Loss per Common Share Basic earnings (loss) per common share is computed by dividing the net earnings (loss) for the period by the weighted average number of common shares outstanding during the period. In periods where there is net income, we apply the two-class method to calculate basic and diluted net income (loss) per share of common stock, as our convertible preferred stock is a participating security. The two-class method is an earnings allocation formula that treats a participating security as having rights to earnings that otherwise would have been available to common stockholders. In periods where there is a net loss, the two-class method of computing earnings per share does not apply as our convertible preferred stock does not contractually participate in our losses. We compute diluted net income (loss) per common share using net income (loss) as the “control number” in determining whether potential common shares are dilutive, after giving consideration to all potentially dilutive common shares, including stock options, unvested restricted stock units outstanding during the period and potential issuance of stock upon the conversion of our convertible preferred stock issued and outstanding during the period, except where the effect of such securities would be antidilutive. The Company did not include any portion of unearned restricted shares, outstanding options, stock appreciation rights, or convertible preferred stock in the calculation of diluted loss per common share because all such securities are anti-dilutive for all periods presented. The application of the two-class method of computing earnings per share under general accounting principles for participating securities is not applicable during these periods because those securities do not contractually participate in its losses. As of December 31, 2022, the Company had <span id="xdx_90E_eus-gaap--AntidilutiveSecuritiesExcludedFromComputationOfEarningsPerShareAmount_pid_c20220101__20221231__us-gaap--AwardTypeAxis__custom--StockOptionsandStockAppreciationRightsMember_ziv9t4ZoeKjk" title="Potential common shares excluded from diluted earnings per share">3,208,065 shares of common stock issuable upon the exercise of outstanding options and stock appreciation rights at a weighted average exercise price of $<span id="xdx_90A_eus-gaap--ShareBasedCompensationArrangementByShareBasedPaymentAwardOptionsOutstandingWeightedAverageExercisePrice_iI_pid_c20221231__us-gaap--AwardTypeAxis__custom--StockOptionsandStockAppreciationRightsMember_zxRC7oMeqddk" title="Weighted average exercise price">4.21 per share, <span id="xdx_90B_eus-gaap--AntidilutiveSecuritiesExcludedFromComputationOfEarningsPerShareAmount_pid_c20220101__20221231__us-gaap--StatementEquityComponentsAxis__custom--SeriesAConvertiblePreferredStockMember_zXw7y8udc5n5" title="Potential common shares excluded from diluted earnings per share">47,364,216 shares of our common stock issuable upon conversion of our Series A Convertible Preferred Stock, <span id="xdx_906_eus-gaap--AntidilutiveSecuritiesExcludedFromComputationOfEarningsPerShareAmount_pid_c20220101__20221231__us-gaap--StatementClassOfStockAxis__custom--SeriesBConvertiblePreferredStockMember_zsvtF6sms6ji" title="Potential common shares excluded from diluted earnings per share">5,610,121 shares of our common stock issuable upon conversion of our Series B Convertible Preferred Stock and <span id="xdx_908_eus-gaap--ShareBasedCompensationArrangementByShareBasedPaymentAwardEquityInstrumentsOtherThanOptionsNonvestedNumber_iI_pid_c20221231__us-gaap--AwardTypeAxis__us-gaap--RestrictedStockMember_zmmkDWsU5WD6" title="Number of unvested restricted share units">1,208,739 shares of unvested restricted share units.

Income Taxes In accordance with general accounting principles for income taxes, a deferred income tax asset or liability is determined based on the difference between the financial statement and tax basis of assets and liabilities as measured by the enacted tax rates that will be in effect when these differences reverse. The Company provides a valuation allowance against net deferred income tax assets unless, based upon available evidence, it is more likely than not the deferred income tax assets will be realized.

Product Warranty Provisions The Company’s standard policy is to warrant all systems against defects in material or workmanship for one year following installation. The Company’s estimate of costs to service the warranty obligations is based on historical experience and current product performance trends. A regular review of warranty obligations is performed to determine the adequacy of the reserve and adjustments are made to the estimated warranty liability (included in other accrued liabilities) as appropriate.

Patent Costs Costs related to filing and pursuing patent applications are expensed as incurred, as recoverability of such expenditures is uncertain.

Concentrations of Risk The majority of the Company’s cash, cash equivalents and investments are deposited with one major financial institution in the U.S. Deposits in this institution exceed the amount of government provided insurance on such deposits.

Recently Issued Accounting Pronouncements In June 2016, the FASB issued ASU 2016-13, “Financial Instruments-Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments” and also issued subsequent amendments to the initial guidance under ASU 2018-19, ASU 2019-04 and ASU 2019-05. The standard modifies the measurement approach for credit losses on financial instruments, including trade receivables, from an incurred loss method to a current expected credit loss method, otherwise known as “CECL.” The standard requires the measurement of expected credit losses to be based on relevant information, including historical experience, current conditions and a forecast that is supportable. The standard is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years; early adoption is permitted. The standard must be adopted by applying a cumulative adjustment to retained earnings. The Company anticipates adopting the standard in the first quarter of 2023, although it does not expect a significant impact to the Company’s financial results.

9. Debt and Credit Facilities The Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) was enacted on March 27, 2020 in the United States. Among the provisions contained in the CARES Act was the creation of the Paycheck Protection Program that provides for Small Business Administration (“SBA”) Section 7(a) loans for qualified small businesses. In general, the loan could be forgiven as long as the funds were used for payroll related expenses as well as rent and utilities paid during the twenty-four-week period from the date of the loan and as long as certain headcount and salary/wage levels were maintained. On April 10, 2020, the Company was informed by its lender, Midwest BankCentre (the “Bank”), that the Bank received approval from the SBA to fund the Company’s request for a loan under the SBA’s Paycheck Protection Program (“PPP Loan”). Per the terms of the PPP Loan, the Company received total proceeds of approximately $2.2 million from the Bank on April 20, 2020. In accordance with the loan forgiveness requirements of the CARES Act, the Company used the full proceeds from the PPP Loan primarily for payroll costs, rent and utilities. In March 2021, the Company applied for loan forgiveness and in June 2021, full loan forgiveness was granted by the SBA. The Company recognized a net gain from debt extinguishment of approximately $<span id="xdx_90B_eus-gaap--GainsLossesOnExtinguishmentOfDebt_pn5n6_c20220101__20221231__us-gaap--LongtermDebtTypeAxis__custom--PaycheckProtectionProgramMember_zSN4Q9A1GOj7" title="Gain on extinguishment of debt">2.2 million.

Each tranche vests upon (i) satisfaction of the market capitalization milestones and (ii) continued employment as CEO of the Company from the grant date through December 31, 2030. Absent an earlier termination, the PSUs will expire on December 31, 2030. If our CEO ceases employment as CEO of the Company for any reason including death, disability, termination for cause or without cause (as defined in the award agreement), or if he voluntary terminates after service as CEO for at least five years, the remaining service period will be waived and he will retain any PSUs that have vested through the date of termination. The Company received Shareholder approval at its annual meeting on May 20, 2021 for shares to be issued under the award. The market capitalization requirement is considered a market condition under FASB Accounting Standards Codification Topic 718 “Compensation – Stock Compensation” and is estimated on the grant date using Monte Carlo simulations. Recognition of stock-based compensation expense of all the tranches commenced on February 23, 2021, the date of grant, as the probability of meeting the ten market capitalization milestones is not considered in determining the timing of expense recognition. The expense will be recognized on an accelerated basis through 2030.

Each tranche represents a portion of the PSUs covering the number of shares outlined in the table above. Each tranche vests upon (i) satisfaction of the market capitalization milestones and (ii) continued employment as CEO of the Company from the grant date through December 31, 2030. Absent an earlier termination, the PSUs will expire on December 31, 2030. If our CEO ceases employment as CEO of the Company for any reason including death, disability, termination for cause or without cause (as defined in the award agreement), or if he voluntary terminates after service as CEO for at least five years, the remaining service period will be waived and he will retain any PSUs that have vested through the date of termination

In general, an “ownership change” will occur if there is a cumulative change in our ownership by “5-percent shareholders” that exceeds 50 percentage points over a rolling three-year period. Similar rules may apply under state tax laws. Following significant ownership changes during 2013, the Company initiated a review of the availability of its U.S. net operating loss carryforwards. As a result of this review, it was determined that a large portion of the Company’s net operating loss carryovers would expire unused due to the limitation under IRC Section 382. The Company reduced the net operating loss carryover and corresponding valuation allowance as a result of these limitations as reflected in the net operating loss carryovers in the table above. The remaining net operating loss carryforwards following the ownership change have been assigned a full valuation allowance against all deferred tax assets. In assessing the realizability of deferred tax assets, the Company considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. The Company considers projected future taxable income and tax planning strategies in making this assessment. Based upon the level of historical taxable losses, and projections for future periods over which the deferred tax assets are deductible, the Company determined that a 100% valuation allowance of deferred tax assets was appropriate. On December 21, 2020, Congress approved the Consolidations Appropriations Act, 2021 (the “Appropriations Act”), which was signed into law by the President on December 27, 2020. The Appropriations Act funded the federal government to the end of the fiscal year 2020 and provided further COVID-19 economic relief. One of the business provisions included in the Appropriations Act is clarification of the income tax deductibility of business expenses that were paid for with the Paycheck Protection Program funds. The Company will continue to monitor for additional legislation related to COVID-19 and its impact on our results of operations. As of December 31, 2022, we had gross federal net operating loss carryforwards of approximately $121.7 million. The federal net operating loss carryforwards reflect accumulated book losses reduced for the 2013 IRC Section 382 ownership change limitation of $236.4 million and approximately $159.2 million of book/tax differences and expiration of unused carryforwards. The federal net operating loss carryforwards generated prior to the 2018 tax year will expire between 2030 and 2037. The federal net operating losses generated in 2018 and thereafter will be carried forward indefinitely as a result of changes in the tax law following the Tax Cuts and Jobs Act. As of December 31, 2022, we had gross state net operating loss carryforward of approximately $<span id="xdx_906_ecustom--OperatingLossCarryforwardsLimitationsOnUseAmount_iI_pn5n6_c20221231__us-gaap--IncomeTaxAuthorityAxis__us-gaap--StateAndLocalJurisdictionMember_zZrLDMoyGedb" title="Operating loss carry forwards">32.8 million which will <span id="xdx_908_eus-gaap--OperatingLossCarryforwardsLimitationsOnUse_c20220101__20221231__us-gaap--IncomeTaxAuthorityAxis__us-gaap--StateAndLocalJurisdictionMember_zCMoDHmJFxNe" title="Operating loss carryforwards limitations on use">expire at various dates between 2023 and 2042 if not utilized.

At December 31, 2022 and 2021, the Company had less than $0.1 million in reserves for uncertain tax positions. The Company recognizes interest accrued, if any, net of tax and penalties, related to unrecognized tax benefits as components of the income tax provision, as applicable. As of December 31, 2022 and 2021, accrued interest and penalties were less than $0.1 million.
