Summary of Significant Accounting Policies | Note 3 Summary of Significant Accounting Policies Since the date of the Annual Report on Form 10‑K for the year ended December 31, 2018, there have been no material changes to the Company’s significant accounting policies, except as disclosed in this note. Concentrations Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash and accounts receivable. A significant portion of the Company’s cash is held at one major financial institution. The Company has not experienced any losses in such accounts. Cash held in US bank institutions is currently insured by the Federal Deposit Insurance Corporation (“FDIC”) up to $250,000 at each institution. There were no uninsured cash balances as of September 30, 2019 and December 31, 2018. Customer concentrations are as follows: Revenues Accounts Receivable For the Three Months Ended For the Nine Months Ended As of As of September 30, September 30, September 30, 2019 December 31, 2018 2019 2018 2019 2018 Customer A 67 % 92 % 46 % 64 % 90 % 63 % Customer B 14 % * 10 % * * * Customer C * * 15 % * * * Customer D * * * 17 % * * Customer E * * * 12 % * * Customer F * * * * * 37 % Total 82 % 92 % 71 % 93 % 90 % 100 % * There is no assurance the Company will continue to receive significant revenues from any of these customers. Any reduction or delay in operating activity from any of the Company’s significant customers, or a delay or default in payment by any significant customer, or termination of agreements with significant customers, could materially harm the Company’s business and prospects. As a result of the Company’s significant customer concentrations, its gross profit and results from operations could fluctuate significantly due to changes in political, environmental, or economic conditions, or the loss of, reduction of business from, or less favorable terms with any of the Company’s significant customers. Revenue Recognition The Company recognizes revenue in accordance with Accounting Standards Codification (“ASC”) Topic 606, “Revenue from Contracts with Customers” (“ASC 606”). The core principle of ASC 606 requires that an entity recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. ASC 606 defines a five-step process to achieve this core principle and, in doing so, it is possible more judgment and estimates may be required within the revenue recognition process, including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. The following five steps are applied to achieve that core principle: · Step 1: Identify the contract with the customer; · Step 2: Identify the performance obligations in the contract; · Step 3: Determine the transaction price; · Step 4: Allocate the transaction price to the performance obligations in the contract; and · Step 5: Recognize revenue when the company satisfies a performance obligation. The Company recognizes revenue primarily from the following different types of contracts: · Product sales – Revenue is recognized at the point the customer obtains controls of the goods and the Company satisfies its performance obligation, which is generally at the time it ships the product to the customer. · Contract services – Revenue is recognized at the point in time that the Company satisfies its performance obligation under the contract, which is generally at the time it delivers a report to the customer. The following table summarizes our revenue recognized in our condensed consolidated statements of operations: For the Three Months Ended For the Nine Months Ended September 30, September 30, 2019 2018 2019 2018 Product sales $ 464,772 $ 482,798 $ 686,522 $ 735,941 Contract services 61,950 — 91,462 145,988 Total revenue $ 526,722 $ 482,798 $ 777,984 $ 881,929 As of September 30, 2019 and December 31, 2018, the Company did not have any contract assets or contract liabilities from contracts with customers. The contract liabilities represent payments received from customers for which the Company had not yet satisfied its performance obligation under the contract. During the three and nine months ended September 30, 2019 and 2018, there was no revenue recognized from performance obligations satisfied (or partially satisfied) in previous periods. Net Loss Per Common Share Basic net loss per common share is computed by dividing net loss by the weighted average number of vested common shares outstanding during the period. Diluted net loss per common share is computed by dividing net loss by the weighted average number of common and dilutive common-equivalent shares outstanding during each period. Dilutive common-equivalent shares consist of shares of non-vested restricted stock, if not anti-dilutive. The following shares were excluded from the calculation of weighted average dilutive common shares because their inclusion would have been anti-dilutive: For the Three Months Ended For the Nine Months Ended September 30, September 30, 2019 2018 2019 2018 Series B Convertible Preferred Stock 724,350 — 724,350 — Series C Convertible Preferred Stock 206,800 — 206,800 — Options 400,000 — 400,000 — Warrants 201,700 — 201,700 — Total 1,532,850 — 1,532,850 — Operating Leases The Company leases properties under operating leases. For leases in effect upon adoption of Accounting Standards Update (“ASU”) 2016‑02, “Leases (Topic 842)” at January 1, 2019 and for any leases commencing thereafter, the Company recognizes a liability to make lease payments, the “lease liability”, and an asset representing the right to use the underlying asset during the lease term, the “right-of-use asset”. The lease liability is measured at the present value of the remaining lease payments, discounted at the Company’s incremental borrowing rate. The right-of-use asset is measured at the amount of the lease liability adjusted for the remaining balance of any lease incentives received, any cumulative prepaid or accrued rent if the lease payments are uneven throughout the lease term, any unamortized initial direct costs, and any impairment of the right-of-use-asset. Operating lease expense consists of a single lease cost calculated so that the remaining cost of the lease is allocated over the remaining lease term on a straight-line basis, variable lease payments not included in the lease liability, and any impairment of the right-of-use asset. The Company evaluated their operating leases and elected to apply the short-term lease measurement and recognition exemption in which the right of use assets and lease liabilities are not recognized for short-term leases. Recently Issued Accounting Pronouncements In July 2019, the FASB issued ASU 2019-07, "Codification Updates to SEC Sections - Amendments to SEC Paragraphs Pursuant to SEC Final Rule Releases No. 33-10532, Disclosure Update and Simplification, and Nos. 33-10231 and 33-10442, Investment Company Reporting Modernization and Miscellaneous Updates (SEC Update)" ("ASU 2019-07"). ASU 2019-07 aligns the guidance in various SEC sections of the Codification with the requirements of certain SEC final rules. ASU 2019-07 is effective immediately. The adoption of ASU 2019-07 did not have a material impact on the Company's unaudited condensed consolidated financial statements. |
