Inventory

Inventory is carried at the lower of cost (first-in, first-out method) or net realizable value. Items in inventory relate predominantly to the Company’s ClearPoint system. Software license inventory related to ClearPoint systems undergoing on-site customer evaluation is included in inventory in the accompanying condensed consolidated balance sheets. All other software license inventory is classified as a non-current asset. The Company periodically reviews its inventory for obsolete items and provides a reserve upon identification of potential obsolete items.

Revenue Recognition

The Company’s revenues are comprised primarily of: (1) product revenues resulting from the sale of functional neurosurgical products, and drug delivery and biologic products; (2) product revenues resulting from the sale of ClearPoint capital equipment; (3) functional neurosurgery and related service revenues resulting from the performance of product line commercialization planning and execution for a third party; (4) clinical case support revenues in connection with customer-sponsored clinical trials; and (5) revenues resulting from the rental, service, installation, training and shipping related to ClearPoint capital equipment. The Company recognizes revenue when control of the Company’s products and services is transferred to its customers in an amount that reflects the consideration the Company expects to receive from its customers in exchange for those products and services. This process involves identifying the contract with a customer, determining the performance obligations in the contract, determining the contract price, allocating the contract price to the distinct performance obligations in the contract, and recognizing revenue when the performance obligations have been satisfied. A performance obligation is considered distinct from other obligations in a contract when it provides a benefit to the customer either on its own or together with other resources that are readily available to the customer and is separately identified in the contract. The Company considers a performance obligation satisfied once it has transferred control of a good or service to the customer, meaning the customer has the ability to use and obtain the benefit of the good or service. The Company recognizes revenue for satisfied performance obligations only when it determines there are no uncertainties regarding payment terms or transfer of control.

Lines of Business; Timing of Revenue Recognition

For both types of capital equipment sales described above, the Company’s determination of the point in time at which to recognize revenue represents that point at which the customer has legal title, physical possession, and the risks and rewards of ownership, and the Company has a present right to payment.

The Company operates in one industry segment, and substantially all its sales are to U.S.-based customers.

Payment terms under contracts with customers generally are in a range of 30-60 days after the customers’ receipt of the Company’s invoices.

The Company provides a one-year warranty on its functional neurosurgery products, biologics and drug delivery systems products, and capital equipment products that are not otherwise covered by a third-party manufacturer’s warranty. The Company’s contracts with customers do not provide for a right of return other than for product defects.

See Note 3 for additional information regarding revenue recognition.

Concentration Risks and Other Risks and Uncertainties

Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash and cash equivalents and accounts receivable. The Company holds its cash and cash equivalents on deposit with financial institutions in the U.S. insured by the Federal Deposit Insurance Corporation. At September 30, 2019, the Company had approximately $280,000 in bank balances that were in excess of the insured limits.

No customer accounted for sales in excess of 10% of total sales in any of the nine-month or three-month periods ended September 30, 2019 or 2018.

At September 30, 2019, an account receivable, related to the Letter of Intent discussed in Note 3, comprised 28% total accounts receivable at that date. Information with respect to accounts receivable from those customers who comprised more than 10% of accounts receivable at December 31, 2018 is as follows:

Prior to granting credit, the Company performs credit evaluations of its customers’ financial condition, and generally does not require collateral from its customers. The Company will provide an allowance for doubtful accounts when collections become doubtful. The allowance for doubtful accounts was approximately $45,000 and $38,000 at September 30, 2019 and December 31, 2018, respectively.

The Company is subject to risks common to emerging companies in the medical device industry, including, but not limited to: new technological innovations; acceptance and competitiveness of its products; dependence on key personnel; dependence on key suppliers; changes in general economic conditions and interest rates; protection of proprietary technology; compliance with changing government regulations; uncertainty of widespread market acceptance of products; access to credit for capital purchases by customers; and product liability claims. Certain components used in manufacturing have relatively few alternative sources of supply and establishing additional or replacement suppliers for such components cannot be accomplished quickly. The inability of any of these suppliers to fulfill the Company’s supply requirements may negatively impact future operating results.
