Summary of Significant Accounting Policies

2. Summary of Significant Accounting Policies

Basis of Presentation

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

Cash and Cash Equivalents

The Company considers all short-term investments purchased with original maturities of three months or less to be cash equivalents. The Company places its cash with high-credit-quality financial institutions and invests primarily in money market accounts. No cash was restricted at December 31, 2019 or 2018.

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.

Financial Instruments

Financial instruments consist of cash and cash equivalents, accounts receivable, accounts payable and debt. The carrying value of such amounts reported at the applicable balance sheet dates approximates fair value.

The Company measures certain financial assets and liabilities at fair value on a recurring basis. General accounting principles for fair value measurement established 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”). As of December 31, 2019 and December 31, 2018 the Company did not have any financial assets or liabilities valued at fair value on a recurring basis.

Inventory

The Company values its inventory at the lower of cost, as determined using the first-in, first-out (FIFO) method, or market. The Company periodically reviews its physical inventory for obsolete items and provides a reserve upon identification of potential obsolete items. Excess manufacturing overhead costs attributable to idle facility expenses, freight, handling costs and wasted material attributable to 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, 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 2 or 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 2 or 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 adopted Accounting Standards Codification Topic 606 (“ASC 606”), Revenue from Contracts with Customers, on January 1, 2018 using the modified retrospective method. Upon adoption of the new revenue guidance, the Company recorded a cumulative-effect reduction to accumulated deficit of $0.3 million on January 1, 2018 relating primarily to the deferral of previously expensed costs to obtain a contract. The Company capitalized sales commissions paid in connection with multi-year service contracts and is amortizing such asset over the economic life of those contracts. Previously, sales commissions on multi-year service contracts were expensed as incurred. The impact of this change on operating expenses in any given period will depend, in part, on the amount of such commissions incurred and capitalized in relation to the amount of ongoing amortization expense.

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 by Biosense Webster of co-developed catheters, 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 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 as necessary.

Systems:

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 not material for the periods presented. Revenue from system delivery and installation represented 7% and 5% of revenue for the years ended December 31, 2019 and 2018, respectively.

Disposables:

Revenue from sales of disposable products is recognized when control is transferred to the customers, which generally occurs at the time of shipment, but can also occur at the time of delivery depending on the customer arrangement. Disposable products are covered by an assurance type warranty that provides for the return of defective products. Warranty costs were not material for the periods presented. Disposable revenue represented 33% of revenue for the years ended December 31, 2019 and 2018, respectively.

Royalty:

The Company is entitled to royalty payments from Biosense Webster, payable quarterly based on net revenues from sales of the co-developed catheters. Royalty revenue from the co-developed catheters represented 10% of revenue for the years ended December 31, 2019 and 2018.

Other Recurring Revenue:

Other recurring revenue includes revenue from product maintenance plans, other post warranty maintenance, and the implied obligation to provide software enhancements if and when available for one year following installation. Revenue from services and software enhancements is deferred and amortized over the service or update period, which is typically one year. Revenue related to services performed on a time-and-materials basis is recognized when performed. Other recurring revenue represented 47% and 52% of revenue for the years ended December 31, 2019 and 2018, respectively.

Sublease Revenue:

The adoption of new lease accounting guidance as of January 1, 2019 requires the Company to record sublease income as revenue beginning in 2019. Sublease revenue represented 3% of revenue for the year ended December 31, 2019.

	Year Ended December 31,
	2019		2018
Systems	$	2,066,253	$	1,582,053
Disposables, service and accessories		25,850,174		27,764,564
Sublease		986,123		-
Total revenue	$	28,902,550	$	29,346,617

Transaction price allocated to remaining performance obligations relates to amounts allocated to products and services for which the revenue has not yet been recognized. A significant portion of this amount relates to the Company’s systems contracts and obligations that will be recognized as revenue in future periods. These obligations are generally satisfied within two years after contract inception but may occasionally extend longer. Transaction price representing revenue to be earned on remaining performance obligations on system contracts was approximately $1.1 million as of December 31, 2019. Performance obligations arising from contracts for disposables, royalty and service are generally expected to be satisfied within one year after entering into the contract.

The following information summarizes the Company’s contract assets and liabilities:

	December 31, 2019			December 31, 2018
Contract Assets - Unbilled Receivables	$	168,445		$	251,867
Customer deposits		-			487,086
Product shipped, revenue deferred		674,324			645,199
Deferred service and license fees		4,972,389			5,100,402
Total deferred revenue		5,646,713			6,232,687
Less: Long-term deferred revenue		(554,258	)		(407,151	)
Total current deferred revenue	$	5,092,455		$	5,825,536

The Company invoices its customers based on the billing schedules in its sales arrangements. 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. 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, 2019 and 2018, that was included in the deferred revenue balance at the beginning of each reporting period was $5.6 million and $5.5 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 sheet was $0.3 million as of December 31, 2019 and December 31, 2018. 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.

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 at December 31, 2019 or 2018 under these types of agreements. Advance receipts or other unearned reimbursements are included in accrued liabilities on the accompanying balance sheet until earned.

Share-Based Compensation

Stock options or stock appreciation rights issued to certain non-employees are recorded at their fair value as determined in accordance with general accounting principles for share-based payments and accounting for equity instruments that are issued to other than employees for acquiring, or in conjunction with selling, goods or services, and recognized over the service period. Deferred compensation for options granted to non-employees is re-measured on a quarterly basis through the vesting or forfeiture date.

The Company utilized the Black-Scholes valuation model to determine the fair value of share-based payments at the date of previously issued grant using risk-free interest rate based on the Treasury yield on the date of the grant and expected volatility based on the Company’s historical volatility over the expected term of the option. The resulting compensation expense is recognized over the requisite service period, generally one to 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 amount to expense over the service period on a straight-line basis for those shares with graded vesting. 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.

Shares purchased by employees under the 2004 Employee Stock Purchase Plan were considered to be compensatory and were accounted for in accordance with general accounting principles for share-based payments. Shares purchased by employees under the 2009 Employee Stock Purchase Plan are considered to be non-compensatory.

Net Earnings (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, warrants, 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, warrants 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, 2019, the Company had 1,857,599 shares of common stock issuable upon the exercise of outstanding options and stock appreciation rights at a weighted average exercise price of $2.22 per share, 46,155 shares of common stock issuable upon the exercise of outstanding warrants at a weighted average exercise price of $0.70 per share, 42,497,068 shares of our common stock issuable upon conversion of our Series A Convertible Preferred Stock, and 5,610,121 shares of our common stock issuable upon conversion of our Series B Convertible Preferred Stock. The Company had no unearned restricted shares outstanding for the period ended December 31, 2019.

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.

Revenue from Biosense Webster Inc. related to royalties and Odyssey System sales accounted for $2.8 million and $2.9 million, or 10%, of total net revenue for the years ended December 31, 2019 and 2018. No other single customer accounted for more than 10% of total revenue for the year ended December 31, 2019. No single country other than the U.S. accounted for more than 10% of total revenue for the years ended December 31, 2019 and 2018.

Reclassifications

Certain amounts in the prior period financial statements have been reclassified to conform to the current period presentation. These reclassifications had no effect on reported losses.

Recently Issued Accounting Pronouncements

Effective January 1, 2019, the Company adopted the Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) 2016-02, Leases (Topic 842), and all subsequent ASUs that modified Topic 842, which sets out the principles for the recognition, measurement, presentation, and disclosure of leases for both parties to a contract (i.e. lessees and lessors). The new standard requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase by the lessee. This classification determines whether lease expense is recognized based on an effective interest method or on a straight line basis over the term of the lease, respectively. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. Leases with a term of 12 months or less are accounted for similar to previous guidance for operating leases. The new standard requires lessors to account for leases using an approach that is substantially equivalent to previous guidance for sales-type leases, direct financing leases and operating leases. Accounting Standards Codification (“ASC 842”) supersedes the previous lease standard, ASC 840 Leases. The Company adopted ASU 2016-02 using the alternative modified transition method. Under this method, the cumulative-effect adjustment to the opening balance of retained earnings is recognized on the date of adoption with prior periods not restated. There was no cumulative-effect adjustment recorded on January 1, 2019. The new standard provides a number of optional practical expedients in transition. The Company elected the ‘package of practical expedients’, which permits it not to reassess under the new standard its prior conclusions about lease identification, lease classification, and initial direct costs. In addition, the new standard provides practical expedients for an entity’s ongoing accounting. The Company elected the practical expedients for ongoing accounting of (1) the election for certain classes of underlying asset to not separate non-lease components from lease components and (2) the election for short-term lease recognition exemption for all leases that qualify. For the Company, as a lessee, the primary impact of adopting ASC 842 was the balance sheet recognition of the right-of-use asset and lease liability for the operating leases. Under the new standard, as a lessor, the Company records the sublease proceeds as Sublease revenue and the related cost as Sublease cost of revenue. See Note 9 for additional details.

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, 2019, 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 2020, although it does not expect a significant impact to the Company’s financial results.

In December 2019, the FASB issued ASU 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes” as part of its effort to reduce the complexity of accounting standards. The ASU is effective for fiscal years beginning after December 15, 2020. The Company does not expect that the adoption of this new guidance will have a material impact on the Company’s financial results.
