Liquidity and Management’s Plans

The Company incurred losses from operations and used cash in operating activities for the three and nine months ended September 30, 2020. The Company’s recurring losses, level of cash used in operations, and need for additional capital in the future, including uncertainties surrounding the impact of COVID-19, raise substantial doubt about the Company’s ability to continue as a going concern. The financial statements do not include any adjustments that might be necessary if the Company is unable to continue as a going concern.

COVID-19 Risk and Uncertainties and CARES Act

The COVID-19 pandemic has severely impacted global economic activity, and many countries and many states in the United States have reacted to the pandemic by instituting quarantines, mandating business and school closures and restricting travel. These mandated business closures have included dental office closures in Europe and the United States for all but emergency procedures. The Company’s salespeople were unable to call on dental customers during these closures. In addition, most dental shows and workshops scheduled in the first and second quarters of 2020 were canceled. Although most dental offices in the United States opened in the third quarter, there is no assurance that they will remain open or the Company’s sales will return to normal levels during at any time during 2020 or at any time thereafter.  The full impact of the COVID-19 outbreak continues to evolve and it is uncertain as to the full magnitude that the pandemic will have on the Company’s financial condition, liquidity, and future results of operations. Management is actively monitoring the global situation on the Company’s financial condition, liquidity, operations, suppliers, industry, and workforce and has taken actions to mitigate the impact including among other things, temporary reductions in pay, furloughs of certain positions and deferrals in payment for cash preservation. Given the daily evolution of the COVID-19 outbreak and the global responses to curb its spread, the Company is not able to estimate the effects of the COVID-19 outbreak on its results of operations, financial condition, or liquidity for fiscal year 2020.

On March 27, 2020, President Trump signed into law the “Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”). The CARES Act, among other things, includes provisions relating to refundable payroll tax credits, deferment of employer side social security payments, net operating loss carryback periods, alternative minimum tax credit refunds, modifications to the net interest deduction limitations, increased limitations on qualified charitable contributions, and technical corrections to tax depreciation methods for qualified improvement property.

As of the date of issuance of these unaudited financial statements, the Company has not yet determined any future impact that the CARES Act will have on our financial condition, results of operations, or liquidity.

Rights Offering

On July 22, 2020, the Company completed a registered rights offering (“the Rights Offering”). Pursuant to the Rights Offering, the Company sold an aggregate of 18,000 units consisting of an aggregate of 18,000 shares of Series F Convertible Preferred Stock and 45,000,000 warrants, with each warrant exercisable for one share of Common Stock, resulting in net proceeds to the Company of approximately $16.1 million, after deducting expenses relating to the Rights Offering, including dealer-manager fees and expenses, and excluding any proceeds received upon exercise of any warrants. See Note 4 for additional information.

As of September 30, 2020, the Company had working capital of approximately $14.6 million. The Company’s principal sources of liquidity as of September 30, 2020 consisted of approximately $19.2 million in cash, cash equivalents and restricted cash and $3.4 million of accounts receivable, net, and approximately $1.0 million of availability under the PMB Loan (as defined below).  

In order for the Company to continue operations beyond the next 12 months and be able to discharge its liabilities and commitments in the normal course of business, the Company must increase sales of its products, control or potentially reduce expenses and establish profitable operations in order to generate cash from operations or obtain additional funds when needed.

Although the Company received gross proceeds of approximately $24.0 million from the equity offerings in the second and third quarters of 2020, the Company may still have to raise additional capital in the future. Additional capital requirements may depend on many factors, including, among other things, the rate at which the Company’s business grows, the COVID-19 pandemic and the actions taken to contain it, demands for working capital, manufacturing capacity, and any acquisitions that the Company may pursue. From time to time, the Company could be required, or may otherwise attempt, to raise capital through either equity or debt offerings. The Company cannot provide assurance that it will be able to successfully enter into any such equity or debt financings in the future or that the required capital would be available on acceptable terms, if at all, or that any such financing activity would not be dilutive to its’ stockholders.

Critical Accounting Policies

Information with respect to the Company’s critical accounting policies, which management believes could have the most significant effect on the Company’s reported results and require subjective or complex judgments by management as discussed in the Company’s 2019 audited financial statements included in the Company’s 2019 Form 10-K. Management believes that there have been no significant changes during the nine months ended September 30, 2020 in the Company’s critical accounting policies from those disclosed in the Company’s 2019 audited financial statements included in the Company’s 2019 Form 10-K.

Concentration of Credit Risk, Interest Rate Risk and Foreign Currency Exchange Rate

Financial instruments which potentially expose the Company to a concentration of credit risk consist principally of cash and cash equivalents, restricted cash, and trade accounts receivable. The Company maintains its cash and cash equivalents and restricted cash with established commercial banks. At times, balances may exceed federally insured limits. To minimize the risk associated with trade accounts receivable, management performs ongoing credit evaluations of customers’ financial condition and maintains relationships with the Company’s customers that allow management to monitor current changes in business operations so the Company can respond as needed. The Company does not, generally, require customers to provide collateral before it sells them its products. However, the Company has required certain distributors to make prepayments for significant purchases of products.

Substantially all of the Company’s revenue is denominated in U.S. dollars, including sales to international distributors. Only a small portion of its revenue and expenses is denominated in foreign currencies, principally the Euro and Indian Rupee. The Company’s foreign currency expenditures primarily consist of the cost of maintaining offices, consulting services, and employee-related costs. During the three and nine month periods ended September 30, 2020 and 2019, the Company did not enter into any hedging contracts. Future fluctuations in the value of the U.S. dollar may affect the price competitiveness of the Company’s products outside the U.S.

REVENUE RECOGNITION

Contracts with Customers

Revenue for sales of products and services is derived from contracts with customers. The products and services promised in customer contracts include delivery of laser systems, imaging systems, and consumables as well as certain ancillary services such as training and extended warranties. Contracts with each customer generally state the terms of the sale, including the description, quantity and price of each product or service. Payment terms are stated in the contract and vary according to the arrangement. Because the customer typically agrees to a stated rate and price in the contract that does not vary over the life of the contract, the Company’s contracts do not contain variable consideration. The Company establishes a provision for estimated warranty expense.

Performance Obligations

At contract inception, the Company assesses the products and services promised in its contracts with customers. The Company then identifies performance obligations to transfer distinct products or services to the customers. In order to identify performance obligations, the Company considers all of the products or services promised in contracts regardless of whether they are explicitly stated or are implied by customary business practices.

Revenue from products and services transferred to customers at a single point in time accounted for 86% and 78% of net revenue for the three and nine months ended September 30, 2020 and 77% and 81% for the three and nine months ended September 30, 2019, respectively. The majority of the Company’s revenue recognized at a point in time is for the sale of laser systems and consumables. Revenue from these contracts is recognized when the customer is able to direct the use of and obtain substantially all of the benefits from the product which generally coincides with title transfer during the shipping process.

Revenue from services transferred to customers over time accounted for 14% and 22% of net revenue for the three and nine months ended September 30, 2020 and 23% and 19% for the three and nine months ended September 30, 2019, respectively. The majority of the Company’s revenue that is recognized over time relates to product training and extended warranties. Deferred revenue attributable to undelivered elements, which primarily consists of product training, totaled approximately $0.5 million and $0.6 million as of September 30, 2020 and December 31, 2019, respectively.

Transaction Price Allocation

The transaction price for a contract is allocated to each distinct performance obligation and recognized as revenue when, or as, each performance obligation is satisfied. For contracts with multiple performance obligations, the Company allocates the contract’s transaction price to each performance obligation using the best estimate of the standalone selling price of each distinct good or service in a contract. The primary method used to estimate standalone selling price is the observable price when the good or service is sold separately in similar circumstances and to similar customers.

Significant Judgments

Revenue is recorded for extended warranties over time as the customer benefits from the warranty coverage. This revenue will be recognized equally throughout the contract period as the customer receives benefits from the Company's promise to provide such services. Revenue is recorded for product training as the customer attends a training program or upon the expiration of the obligation, which is generally after nine months.  

The Company also has contracts that include both the product sales and product training as performance obligations. In those cases, the Company records revenue for product sales at the point in time when the product has been shipped. The customer obtains control of the product when it is shipped, as all shipments are made FOB shipping point, and after the customer selects its shipping method and pays all shipping costs and insurance. The Company has concluded that control is transferred to the customer upon shipment.

Accounts Receivable

Accounts receivable are stated at estimated net realizable value. The allowance for doubtful accounts is based on an analysis of customer accounts and the Company’s historical experience with accounts receivable write-offs. During the nine months ended September 30, 2020, the Company recorded an additional allowance for doubtful accounts of approximately $1.3 million due to the uncertainties stemming from the impact of COVID-19.  

Contract Liabilities

The Company performs its obligations under a contract with a customer by transferring products and/or services in exchange for consideration from the customer. The Company typically invoices its customers as soon as control of an asset is transferred and a receivable for the Company is established. The Company, however, recognizes a contract liability when a customer prepays for goods and/or services and the Company has not transferred control of the goods and/or services. The opening and closing balances of the Company’s contract liabilities are as follows (in thousands):

The balance of contract assets was immaterial as the Company did not have a significant amount of uninvoiced receivables at September 30, 2020 and December 31, 2019.

The amount of revenue recognized during the nine-month period ended September 30, 2020 and September 30, 2019 that was included in the opening contract liability balance related to undelivered elements was $0.3 million. and $0.1 million, respectively.   

Disaggregation of Revenue

The Company disaggregates revenue from contracts with customers into geographical regions and by the timing of when goods and services are transferred. The Company determined that disaggregating revenue into these categories depicts how the nature, amount, timing and uncertainty of revenue and cash flows are affected by regional economic factors.

The Company’s revenues related to the following geographic areas were as follows for the periods indicated (in thousands):

Information regarding revenues disaggregated by the timing of when goods and services are transferred is as follows (in thousands):

The Company’s sales by end market were as follows for the periods indicated (in thousands):

The Company acts as the principal in all its imaging equipment distribution sales. The Company takes possession and control of the equipment before they are sold and transferred to the customer. The Company provides the equipment and any related services directly to the customer. The Company has inventory risk before the equipment is transferred to a customer. The Company purchases and obtains the goods before obtaining a contract with a customer. The Company also has discretion in establishing the price sold to the customer for the equipment.

Shipping and Handling Costs and Revenues

Shipping and freight costs are treated as fulfillment costs. For shipments to end-customers, the customer bears the shipping and freight costs and has control of the product upon shipment. For shipments to distributors, the distributor bears the shipping and freight costs, including insurance, tariffs and other import/export costs.
