Summary of Significant Accounting Policies
Basis of Presentation
The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and pursuant to Article 10 of Regulation S-X of the Securities Act of 1933, as amended (“Securities Act”). Accordingly, they do not include all of the information and notes required by U.S. GAAP for complete financial statements. These unaudited condensed consolidated financial statements include all normal and recurring adjustments that the Company believes are necessary to fairly state the Company’s financial position and the results of operations and cash flows. Interim period results are not necessarily indicative of results of operations or cash flows for a full year or any subsequent interim period. The condensed consolidated balance sheet as of December 31, 2017 has been derived from audited consolidated financial statements at that date, but does not include all disclosures required by U.S. GAAP for complete financial statements.
Deferred Offering Costs
Deferred offering costs, consisting of legal, accounting, filing and other fees related to the IPO were capitalized during our IPO process. During the three months ended September 30, 2018, $607,000 in deferred offering costs were reclassified to additional paid-in capital upon the effectiveness of the IPO. As of December 31, 2017, $54,000 of deferred offering costs were capitalized and included in other assets on the condensed consolidated balance sheet.
Use of Estimates
The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.
Concentration of Credit Risk 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. Cash and cash equivalents are deposited in demand and money market accounts at one financial institution. At times, such deposits may be in excess of insured limits. The Company has not experienced any losses on its deposits of cash and cash equivalents.
The Company’s accounts receivable are derived from revenue earned from customers located throughout the world. The Company performs credit evaluations of its customers’ financial condition and sometimes requires partial payment in advance of shipping. As of September 30, 2018, the Company had two customers accounting for 89% and 11% of accounts receivable. As of December 31, 2017, the Company had two customers accounting for 74% and 12% of accounts receivable. The Company had two customers accounting for 51% and 45% of its net revenue for the three months ended September 30, 2018. The Company had one customers accounting for 92% of its net revenue for the three months ended September 30, 2017. The Company had two customers accounting for 59%, and 32% of its net revenue for the nine months ended September 30, 2018. The Company had three customers accounting for 50%, 31% and 8% of its net revenue for the nine months ended September 30, 2017.
The Company’s future results of operations involve a number of risks and uncertainties. Factors that could affect the Company’s future operating results and cause actual results to vary materially from expectations include, but are not limited to, rapid technological change, continued acceptance of the Company’s products, competition from substitute products and larger companies, protection of proprietary technology, strategic relationships and dependence on key individuals.
The Company relies on sole-source suppliers to manufacture some of the components used in its product. The Company’s manufacturers and suppliers may encounter problems during manufacturing due to a variety of reasons, any of which could delay or impede their ability to meet demand. The Company is heavily dependent on a single contractor in China for assembly and testing of its products.
Convertible Financial Instruments
The Company bifurcates conversion options and warrants from their host instruments and accounts for them as freestanding derivative financial instruments if certain criteria are met. The criteria include circumstances in which (a) the economic characteristics and risks of the embedded derivative instrument are not clearly and closely related to the economic characteristics and risks of the host contract, (b) the hybrid instrument that embodies both the embedded derivative instrument and the host contract is not re-measured at fair value under otherwise applicable generally accepted accounting principles with changes in fair value reported in earnings as they occur and (c) a separate instrument with the same terms as the embedded derivative instrument would be considered a derivative instrument. An exception to this rule is when the host instrument is deemed to be conventional, as that term is described under applicable U.S. GAAP.
When the Company has determined that the embedded conversion options and warrants should be bifurcated from their host instruments, discounts are recorded for the intrinsic value of conversion options embedded in the instruments based upon the differences between the fair value of the underlying common stock at the commitment date of the transaction and the effective conversion price embedded in the instrument.
Debt discounts under these arrangements are amortized to interest expense using the interest method over the earlier of the term of the related debt or their earliest date of redemption.
The Company has pledged all its assets, including its personal property, fixtures, intellectual property and products as collateral for certain of its promissory and convertible notes payable.
Warrants for Common Shares and Derivative Financial Instruments
Warrants for common shares and other derivative financial instruments are classified as equity if the contracts (1) require physical settlement or net-share settlement or (2) give the Company a choice of net-cash settlement or settlement in its own shares (physical settlement or net-share settlement). Contracts which (1) require net-cash settlement (including a requirement to net cash settle the contract if an event occurs and if that event is outside the control of the Company), (2) give the counterparty a choice of net-cash settlement or settlement in shares (physical settlement or net-share settlement), or (3) that contain reset provisions that do not qualify for the scope exception are classified as equity or liabilities. The Company assesses classification of its warrants for common shares and other derivatives at each reporting date to determine whether a change in classification between equity and liabilities is required.
The issuance of the convertible notes payable generated a beneficial conversion feature (“BCF”), which arises when a debt or equity security is issued with an embedded conversion option that is beneficial to the investor or in the money at inception because the conversion option has an effective strike price that is less than the market price of the underlying stock at the commitment date. The Company recognized the BCF by allocating the intrinsic value of the conversion option, which is the number of shares of common stock available upon conversion multiplied by the difference between the effective conversion price per share and the fair value of common stock per share on the commitment date, to common shares, resulting in a discount on the convertible debt.
Revenue Recognition
Revenue is recognized when control of the promised goods or services is transferred to customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services. Sales of products with alternative use account for the majority of our revenue and are recognized at a point in time.
Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction, that are collected by us from a customer and deposited with the relevant government authority, are excluded from revenue. Our revenue arrangements do not contain significant financing components.
Sales to certain distributors are made under arrangements which provide the distributors with price adjustments, price protection, stock rotation and other allowances under certain circumstances. The Company does not provide its customers with a contractual right of return. However, the Company accepts limited returns on a case-by-case basis. These returns, adjustments and other allowances are accounted for as variable consideration. We estimate these amounts based on the expected amount to be provided to customers and reduce revenue recognized. We believe that there will not be significant changes to our estimates of variable consideration.
If a customer pays consideration, or the Company has a right to an amount of consideration that is unconditional before we transfer a good or service to the customer, those amounts are classified as deferred income/ advances received from customers which are included in other current liabilities when the payment is made or it is due, whichever is earlier.
Comprehensive Loss
Comprehensive loss includes all changes within stockholders’ equity (deficit) that are not the result of transactions with stockholders. Accumulated other comprehensive loss includes the foreign currency translation adjustments arising from the consolidation of the Company’s foreign subsidiary.
Foreign Currency
The financial position and results of operations of the Company’s foreign operations are measured using currencies other than the U.S. dollar as their functional currencies. Accordingly, for these operations all assets and liabilities are translated into U.S. dollars at the current exchange rates as of the respective balance sheet date. Expense items are translated using the weighted average exchange rates prevailing during the period. Cumulative gains and losses from the translation of these operations’ financial statements are reported as a separate component of stockholders’ equity (deficit), while foreign currency transaction gains or losses, resulting from remeasuring local currency to the U.S. dollar are recorded in the condensed consolidated statement of operations in other income (expense), net and were not material for the three and nine months ended September 30, 2018 and 2017.
Advertising Costs
Advertising costs are charged to sales and marketing expenses as incurred. Advertising costs for the three and nine months ended September 30, 2018 and 2017 were not material.
Net Loss per Common Share
Basic net loss per common share is calculated by dividing the net loss by the weighted average number of common shares outstanding during the period, without consideration for potentially dilutive securities. Diluted net loss per common share is computed by dividing the net loss by the weighted average number of common shares and potentially dilutive common share equivalents outstanding for the period determined using the treasury-stock and if-converted methods. For purposes of the diluted net loss per common share calculation, preferred stock, warrants for common stock, restricted stock units and shares issuable upon the conversion of convertible notes payable are considered to be potentially dilutive securities.
For the three and nine months ended September 30, 2018, warrants to purchase 8,601,813 shares of common stock, and 943,352 shares of restricted stock have been excluded from the calculation of net loss per common share because the inclusion would be antidilutive.  For the three and nine months ended September 30, 2017, warrants to purchase 2,176,469 shares of common stock and 2,762,594 shares of preferred stock have been excluded from the calculation of net loss per common share because the inclusion would be antidilutive.  In addition, shares issuable upon the conversion of convertible notes payable have been excluded from the calculation of net loss per common share for all periods presented because the inclusion would be antidilutive.
Recent Accounting Pronouncements
In May 2014, the Financial Accounting Standards Board (“FASB”) issued an Accounting Standards Update (“ASU”) on revenue from contracts with customers, ASU No. 2014-09, Revenue from Contracts with Customers (“Topic 606”). This standard update outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers. The guidance is effective for annual reporting periods including interim reporting reports beginning after December 15, 2017. Collectively, we refer to Topic 606, its related amendments and Subtopic 340-40 as the “new standard”.
On January 1, 2018, we adopted the new standard using the modified retrospective method applied to all contracts that are not completed contracts at the date of initial application (i.e., January 1, 2018). Results for reporting periods after January 1, 2018 are presented under the new standard, while prior period amounts are not adjusted and continue to be reported in accordance with our historic accounting. There was no impact on the opening accumulated deficit as of January 1, 2018 due to the adoption of the new standard.
We have reviewed other recent accounting pronouncements and concluded they are either not applicable to the business, or no material effect is expected on the condensed consolidated financial statements as a result of future adoption.
