Organization and Description of Business

1.ORGANIZATION AND DESCRIPTION OF BUSINESS

Mohawk Group Holdings, Inc. and subsidiaries (“Mohawk” or the “Company”) is a rapidly growing technology-enabled consumer products company that uses machine learning, natural language processing, and data analytics to design, develop, market and sell products. Mohawk predominately operates through online retail channels such as Amazon and Walmart.

Headquartered in New York, Mohawk’s other offices can be found in China, Philippines, Israel, and Poland.

Merger—On September 4, 2018, pursuant to an Agreement and Plan of Merger and Reorganization among the Company, MGH Merger Sub, Inc. and Mohawk Group, Inc. (“MGI”), as amended by Amendment No. 1 dated as of April 1, 2018 (the “Merger Agreement”), MGI merged with Merger Sub, Inc., with MGI remaining as the surviving entity and becoming a wholly-owned operating subsidiary of the Company (the “Merger”). The Merger was a reverse recapitalization for financial reporting purposes. The Merger is reflected in the financial statements and financial disclosures as if the Merger was effective on January 1, 2017. Operations prior to the Merger are the historical operations of MGI.

Under the Merger Agreement, all outstanding shares of common stock, shares of preferred stock and warrants, excluding MGI’s Series C preferred stock (“Series C”) and warrants to purchase shares of Series C, converted to shares of common stock of the Company at a ratio of 1 to 0.3131 (the “Conversion”). All outstanding Series C converted on a 1 to 0.2564 basis to shares of common stock of the Company and all outstanding warrants to purchase shares of Series C converted to warrants to purchase shares of common stock of the Company on a 1 to 0.2564 basis. At the time of the merger, the Company had 0.9 million shares outstanding held by certain Series C holders.

Initial Public Offering—On June 14, 2019, the Company completed its initial public offering (“IPO”), selling 3,600,000 shares of common stock at a public offering price of $10.00 per share. Net proceeds to the Company from the offering were approximately $29.4 million, after deducting legal, underwriting and other offering expenses.

Liquidity and Going Concern— The Company is an early-stage growth company. Accordingly, the Company endeavors to continuously invest in the launch of new products, the development of its software, and the expansion of its sales and distribution infrastructure in order to accelerate revenue growth and scale operations to support such growth. To fund these investments, the Company has historically obtained financing and raised capital since its inception with the expectation that the Company will generate profits in the future. The Company intends to continue to its strategy of investing in growth by launching new products, developing its software and expanding its sales and distribution operations for the foreseeable future.

As a result of its historical investments, the Company has incurred operating losses since its inception, which includes an operating loss of $54.3 million for the year ended December 31, 2019 and had an accumulated deficit of $129.8 million, cash on hand of $30.4 million, and total outstanding borrowing from lenders of $35.1 million with no available capacity as of December 31, 2019. The Company has raised $102.0 million in equity financing to fund its operations since inception, including the net proceeds from the IPO, through December 31, 2019.

In addition, while the Company anticipates it will remain in compliance with the covenants prescribed by its existing financing arrangements (See Note 9 – Credit Facility and Term Loans), there can be no assurance that the Company’s operating forecast and cash flows for the twelve months following the issuance of the accompanying consolidated financial statements will be attained such that the Company will be able to maintain compliance with these covenants or generate sufficient liquidity to fund its ongoing operations. These negative financial conditions raise substantial doubt about the Company’s ability to continue as a going concern as of December 31, 2019.

Management plans to continue to closely monitor its operating forecast and cash flows, and may pursue additional sources of financing and/or capital to fund its operations. If the Company is unable to improve its operating results, increase its operating cash inflows, and/or obtain additional sources of financing and capital on acceptable terms (if at all), the Company may have to make significant changes to its operating plan, such as delay expenditures, reduce investments in new products, delay the development of its software, reduce its sale and distribution infrastructure, or otherwise significantly reduce the scope of its business. The accompanying consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty. See Note 17 – Subsequent Events.

Summary of Significant Accounting Policies

2.	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation—The consolidated financial statements and accompanying notes have been prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”).

Use of Estimates—Preparation of financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period covered by the financial statements and accompanying notes. The most significant estimates relate to the determination of fair value of the Company’s common stock and stock-based compensation. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment, and makes adjustments when facts and circumstances dictate. As future events and their effects cannot be determined with precision, actual results could differ from those estimates.

Principles of Consolidation—The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All inter-company balances and transactions have been eliminated in consolidation.

Fair Value of Financial Instruments—The Company’s financial instruments, including cash, restricted cash, net accounts receivable, accounts payable, and accrued and other current liabilities are carried at historical cost. At December 31, 2018 and 2019, the carrying amounts of these instruments approximated their fair values because of their short-term nature. The term loans and credit facility are carried at amortized cost and at December 31, 2019, the carrying amount approximates fair value as the stated interest rate approximates market rates currently available to the Company.

Assets and liabilities recorded at fair value on a recurring basis in the Consolidated Balance Sheets are categorized based upon the level of judgment associated with the inputs used to measure their fair values. Fair value is defined as the exchange price that would be received for an asset or an exit price that would be paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The authoritative guidance on fair value measurements establishes a three-tier fair value hierarchy for disclosure of fair value measurements as follows:

Level 1—Inputs are unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date;

Level 2—Inputs are observable, unadjusted quoted prices in active markets for similar assets or liabilities, unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the related assets or liabilities; and

Level 3—Unobservable inputs that are supported by little or no market data for the related assets or liabilities.

The categorization of a financial instrument within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement.

Goodwill—Goodwill is the excess of the acquisition cost of an acquired business over the fair value of the identifiable net assets acquired. Goodwill and other indefinite lived intangible assets are not amortized. These assets are reviewed annually (or more frequently under various conditions) for impairment using a fair value approach. The Company performs its annual, or interim, goodwill impairment test by comparing the fair value of its reporting units with their carrying amounts. The Company expects to perform its annual impairment testing during the fourth quarter of the calendar year. The Company would recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized would not exceed the total amount of goodwill allocated to that reporting unit. Additionally, the Company considers income tax effects from any tax-deductible goodwill on the carrying amount of its reporting unit when measuring the goodwill impairment loss, if applicable. The fair value of the reporting units is estimated using discounted cash flow methodologies, as well as considering third party market value indicators. The Company’s use of a discounted cash flow methodology includes estimates of future revenue based upon budgets and projections. The Company also develops estimates for future levels of gross and operating profits and projected capital expenditures. The Company’s methodology also includes the use of estimated discount rates based upon industry and competitor analysis as well as other factors. Calculating the fair value of the reporting units requires significant estimates and assumptions by management. Should the estimates and assumptions regarding the fair value of the reporting units prove to be incorrect, the Company may be required to record impairments to its goodwill in future periods and such impairments could be material.

The Company has the option to perform a qualitative assessment to determine whether it is necessary to perform the quantitative goodwill impairment test. However, the Company may elect to perform the quantitative goodwill impairment test even if no indications of a potential impairment exist. The Company performed its goodwill impairment test in the fourth quarter of 2019. No material changes have occurred since testing and it was determined that there was no impairment for the year-ended December 31, 2019.

Restricted Cash—The Company has restricted cash with its primary banks for use as collateral with its credit cards and required minimum restricted capital for its Chinese subsidiary. As of December 31, 2018, the Company has classified $0.6 million in prepaid and other current assets for collateral of its credit cards and $0.1 million cash for its Chinese subsidiary, within other non-current assets, as restricted cash. As of December 31, 2019, the Company has classified in restricted cash consisting of $0.3 million for collateral with its credit cards in prepaid and other current assets and $0.1 million related to its Chinese subsidiary, within other non-current assets on the Consolidated Balance Sheets.

Accounts Receivable—Accounts receivable are stated at historical cost less allowance for doubtful accounts. On a periodic basis, management evaluates its accounts receivable and determines whether to provide an allowance or if any accounts should be written off based on past history of write-offs, collections and current credit conditions. A receivable is considered past due if the Company has not received payments based on agreed-upon terms. The Company generally does not require any security or collateral to support its receivables. The Company performs on-going evaluations of its customers and maintains an allowance for bad and doubtful receivables. At December 31, 2018 and 2019, the allowance for doubtful accounts was $0.0 million and $0.0 million, respectively.

Concentration of Credit Risk—Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and accounts receivable. The Company maintains cash and restricted cash with various domestic and foreign financial institutions of high credit quality. The Company performs periodic evaluations of the relative credit standing of all of the aforementioned institutions.

The Company’s accounts receivables are derived from sales contracts with a large number of customers. The Company maintains reserves for potential credit losses on customer accounts when deemed necessary. Significant customers are those which represent more than 10% of the Company’s total net revenue or gross accounts receivable balance at the balance sheet date. During the years ended December 31, 2018 and 2019, the Company had no customer that accounted for 10% or more of total net revenue. In addition, as of December 31, 2018 and 2019, the Company has no customer that accounted for 10% or more of gross accounts receivable. As of December 31, 2018 and 2019, approximately 79% and 74%, respectively, of its accounts receivable is held by the Company’s sales platform vendor Amazon, which collects money on the Company’s behalf from its customers.

The Company’s business is reliant on one key vendor which currently provides the Company with its sales platform, logistics and fulfillment operations, including certain warehousing for the Company’s net goods, and invoicing and collection of its revenue from the Company’s end customers. In 2018, approximately 95% of the Company’s revenue was through or with the Amazon sales platform and in 2019, 95% of its net revenue was through or with the Amazon sales platform.

Property and Equipment—Property and equipment are stated at cost less accumulated depreciation and amortization. Depreciation is provided for using the straight-line method over the estimated useful lives of the assets. Capital leases and leasehold improvements are amortized using the straight-line method over the shorter of the lease term or estimated useful life of the asset. Costs of maintenance and repairs that do not improve or extend the lives of the respective assets are expensed as incurred.

The estimated useful lives for significant property and equipment categories are as follows:

Computer equipment and software

3 years

Furniture, fixtures, and equipment

3-5 years

Leasehold improvements and capital leases

Shorter of remaining

lease term or

estimated useful life

Income Taxes—The Company accounts for income taxes under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to operating loss carry-forwards and temporary differences between financial statement bases of existing assets and liabilities and their respective income tax bases. Deferred tax assets and liabilities are measured using enacted income tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect of a change in the income tax rates on deferred tax asset and liability balances is recognized in income in the period that includes the enactment date of such rate change. A valuation allowance is recorded for loss carry-forwards and other deferred tax assets when it is determined that it is more likely than not that such loss carry-forwards and deferred tax assets will not be realized. The Company recognizes the tax benefits on any uncertain tax positions taken or expected to be taken in the consolidated financial statements when it is more likely than not the position will be realized upon ultimate settlement with the tax authority assuming full knowledge of the position and relevant facts. The tax benefits recognized in the consolidated financial statements from such a position are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. The Company recognizes estimated interest and penalties related to uncertain tax positions as a part of the provision for income taxes.

Revenue Recognition—The Company accounts for revenue in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standard Codification (“ASC”) Topic 606, Revenue from Contracts with Customers. The Company adopted ASC Topic 606 as of January 1, 2017 using the full retrospective method. The standard did not affect the Company’s consolidated net loss, financial position, or cash flows. There were no changes to the timing of revenue recognition as a result of the adoption.

The Company derives its revenue from the sale of consumer products. The Company sells its products directly to consumers through online retail channels and through wholesale channels.

For direct to consumer sales, the Company considers customer order confirmations to be a contract with the customer. Customer confirmations are executed at the time an order is placed through third party online channels. For wholesale sales, the Company considers the customer purchase order to be the contract.

For all of the Company’s sales and distribution channels, revenue is recognized when control of the product is transferred to the customer (i.e., when the Company’s performance obligation is satisfied), which typically occurs at shipment date. As a result, the Company has a present and unconditional right to payment and record the amount due from the customer in accounts receivable.

Revenue from consumer product sales is recorded at the net sales price (transaction price), which includes an estimate of future returns based on historical return rates. There is judgment in utilizing historical trends for estimating future returns. The Company’s refund liability for sales returns was $0.3 million and $0.5 million at December 31, 2018 and 2019, respectively, which is included in accrued liabilities and represents the expected value of the refund that will be due to its customers.

The Company evaluated principal versus agent considerations to determine whether it is appropriate to record platform fees paid to Amazon as an expense or as a reduction of revenue. Platform fees are recorded as sales and distribution expense and are not recorded as a reduction of revenue because it owns and controls all the goods before they are transferred to the customer. The Company can, at any time, direct Amazon and similarly with other 3rd party logistics providers (“Logistics Providers”), to return the Company’s inventory to any location specified by the Company. Any returns made by customers directly to Logistic Providers is the responsibility of the Company to make customers whole and the Company retains the back-end inventory risk. Further, the Company is subject to credit risk (i.e., credit card chargebacks), establishes prices of its products, can determine who fulfills the goods to the customer (Amazon or the Company) and can limit quantities or stop selling the goods at any time. Based on these considerations, the Company is the principal in this arrangement.

Performance Obligations. A performance obligation is a promise in a contract to transfer a distinct good to the customer and is the unit of account in ASC Topic 606. A contract’s transaction price is recognized as revenue when the performance obligation is satisfied. Each of the Company’s contracts have a single distinct performance obligation, which is the promise to transfer individual goods.

For consumer product sales, the Company has elected to treat shipping and handling as fulfillment activities, and not a separate performance obligation. Accordingly, the Company recognizes revenue for its single performance obligation related to product sales at the time control of the merchandise passes to the customer, which is generally at the time of shipment. The Company bills customers for charges for shipping and handling on certain sales and such charges are recorded as part of net revenue. Shipping and handling revenue for year-end December 31, 2018 and 2019 were $0.0 million and $0.0 million, respectively.

For each contract, the Company considers the promise to transfer products to be the only identified performance obligation. In determining the transaction price, the Company evaluates whether the price is subject to refund or adjustment to determine the net consideration to which the Company expects to be entitled.

All of the Company’s direct and wholesale revenue for the years ended December 31, 2018 and 2019 are recognized at a point in time.

Sales taxes—Consistent with prior periods, sales taxes collected from customers are presented on a net basis and as such are excluded from net revenue.

Inventory and cost of goods sold—The Company’s inventory consists almost entirely of finished goods. The Company currently records inventory on its balance sheet on a first-in first-out (“FIFO”) basis, or net realizable value, if it is below the Company’s recorded cost. The Company’s costs include the amounts it pays manufacturers for product, tariffs and duties associated with transporting product across national borders, and freight costs associated with transporting the product from its manufacturers to its warehouses, as applicable.

The “Cost of goods sold” line item in the consolidated statements of operations is comprised of the book value of inventory sold to customers during the reporting period. When circumstances dictate that the Company use net realizable value as the basis for recording inventory, it bases its estimates on expected future selling prices less expected disposal costs.

Sales and Distribution—Sales and distribution expenses consist of online advertising costs, marketing and promotional costs, sales and platform commissions, fulfillment, including shipping and handling, warehouse costs and employee compensation and benefits. Costs associated with the Company’s advertising and sales promotion are expensed as incurred and are included in sales and distribution expenses. For the years ended

December 31, 2018 and 2019, the Company recognized $4.5 million and $4.8 million, respectively, for advertising costs, which consists primarily of online advertising expense. Shipping and handling expense are included in the Company’s consolidated statements of operations within sales and distribution expenses. This includes pick and pack costs and outbound transportation costs to ship goods to customers performed by e-commerce platforms or incurred directly by the Company’s own fulfillment operations. The Company’s expense for shipping and handling was $11.4 million and $17.2 million during fiscal 2018 and 2019, respectively.

Research and Development—Research and development expenses include compensation and employee benefits for technology development employees, travel related costs, and fees paid to outside consultants related to development of the Company’s owned intellectual property.

General and Administrative—General and administrative expenses include compensation and employee benefits for executive management, finance administration, legal, and human resources, facility costs, travel, professional service fees and other general overhead costs.

Stock-Based Compensation—Stock-based compensation expense to employees is measured based on the grant-date fair value of the awards and recognized in the consolidated statements of operations over the period during which the employee is required to perform services in exchange for the award (the vesting period of the award). The Company estimates the fair value of stock options granted using the Black-Scholes option valuation model.

The Black-Scholes option-pricing model requires the input of highly subjective assumptions, including the fair value of the Company’s underlying common stock, the expected term of stock options, the expected volatility of the price of its common stock, risk-free interest rates and the expected dividend yield of its common stock. The assumptions used in the Company’s option-pricing model represent management’s best estimates. These estimates involve inherent uncertainties and the application of management’s judgment. If factors change and different assumptions are used, the Company’s stock-based compensation expense could be materially different in the future.

These assumptions are estimated as follows:

•

Fair Value of Common Stock. Because the Company’s common stock is not publicly traded, it must estimate the fair value of common stock, as discussed in the section “Common Stock Valuation” below.

•

Risk-Free Interest Rate. The Company based the risk-free interest rate used in the Black-Scholes valuation model on the implied yield available on U.S. Treasury zero-coupon bonds with an equivalent remaining term of the stock options for each stock option group.

•

Expected Term. The Company determines the expected term based on the average period the stock options are expected to remain outstanding generally calculated as the midpoint of the stock options vesting term and contractual expiration period, as it does not have sufficient historical information to develop reasonable expectations about future exercise patterns and post-vesting employment termination behavior.

•

Expected Volatility. The Company determines the price volatility factor based on the historical volatility of publicly-traded industry peers. To determine its peer group of companies, the Company considers public companies in the technology industry and selects those that are similar to the Company in size, stage of life cycle and financial leverage. The Company does not rely on implied volatilities of traded options in its industry peers’ common stock because the volume of activity is relatively low.

•

Expected Dividend Yield. The Company has not paid and does not anticipate paying any cash dividends in the foreseeable future and, therefore, use an expected dividend yield of zero.

If any of the assumptions used in the Black-Scholes option-pricing model changes significantly, stock-based compensation for future awards may differ materially compared with the awards granted previously. The Company recognizes forfeitures as they occur, which results in a reduction in compensation expense at the time of forfeiture.

Common Stock Valuation The fair value of the Company’s common stock underlying stock options has historically been determined by its board of directors, with assistance from management and contemporaneous third-party valuations. Given the absence of a public trading market for its common stock prior to the Company’s IPO in 2019, and in accordance with the American Institute of Certified Public Accountants Practice Aid, Valuation of Privately Held Company Equity Securities Issued as Compensation, or the Practice Aid, the Company’s board of directors has exercised reasonable judgment and considered numerous objective and subjective factors to determine the best estimate of the fair value of its common stock at each grant date. These factors include:

•

contemporaneous third-party valuations of the Company’s common stock;

•

the Company’s operating and financial performance;

•

current business conditions and projections;

•

the likelihood of achieving a liquidity event for the shares of common stock underlying these stock options, such as an initial public offering or sale of the company, given prevailing market conditions;

•

the lack of marketability of the Company’s common stock;

•

the market performance of comparable publicly-traded e-commerce and technology companies; and

•

the U.S. and global economic and capital market conditions and outlook.

In determining the fair value of the Company’s common stock, it estimated the enterprise value of its business using the market approach and the income approach. Under the income approach, forecast cash flows are discounted to the present value at a risk-adjusted discount rate. The valuation analyses determine discrete free cash flows over several years based on forecast financial information provided by the Company’s management and a terminal value for the residual period beyond the discrete forecast, which are discounted at its estimated weighted-average cost of capital to estimate its enterprise value. Under the market approach, a group of guideline publicly-traded companies with similar financial and operating characteristics as the Company is selected, and valuation multiples based on the guideline public companies’ financial information and market data are calculated. Based on the observed valuation multiples, an appropriate multiple was selected to apply to the Company’s historical and forecasted revenue results. The estimated enterprise value is then allocated to the common stock using the Option Pricing Method (OPM), and the Probability Weighted Expected Return Method (PWERM), or the hybrid method. The hybrid method applied the PWERM utilizing the probability of an exit scenario, and the OPM was used in the remaining private scenario.

For options granted prior to October 2018, the Company has used a hybrid method to determine the fair value of its common stock. Under the hybrid method, multiple valuation approaches were used and then combined into a single probability weighted valuation using a PWERM. The Company’s approach for options granted starting in October 1, 2018 included the use of an initial public offering scenario and a scenario assuming continued operation as a private entity. Following the closing of the Company’s initial public offering, the fair value per share of its common stock for purposes of determining stock-based compensation will be the closing price of its common stock as reported on the applicable grant date.

Deferred offering costs—Deferred offering costs, which consist of direct incremental legal, consulting, banking and accounting fees relating to anticipated equity offerings, are capitalized and will be offset against proceeds upon the consummation of the offerings within stockholders’ equity. In the event an anticipated offering is terminated, deferred offering costs will be expensed. As of December 31, 2018, there were $1.2 million of deferred offering costs categorized in prepaids and other current assets in the consolidated balance sheets. As of December 31, 2019, there were no remaining deferred offering costs categorized in prepaids and other current assets in the consolidated balance sheets.

Foreign Currency—The functional currency of the Company’s foreign subsidiaries is the local currency. All assets and liabilities of foreign subsidiaries are translated at the current exchange rate as of the end of the period, and revenues and expenses are translated at the average exchange rates in effect during the period. The gain or loss resulting from the process of translating foreign currency financial statements into U.S. dollars is reflected as a foreign currency cumulative translation adjustment and reported as a component of accumulated other comprehensive income loss. Foreign currency transaction gains and losses resulting from or expected to result from transactions denominated in a currency other than the functional currency are recognized in other expense, net in the consolidated statements of operations. The Company recorded net loss from foreign currency transactions of less than $0.1 million and less than $0.1 million for the years ended December 31, 2018 and 2019.

Net Loss Per Share—The Company computes basic earnings per share using the weighted-average number of shares of common stock outstanding during the period. For periods in which the Company reports net losses, diluted net loss per share attributable to stockholders is the same as basic net loss per share attributable to stockholders, because potentially dilutive common shares are not assumed to have been issued if their effect is anti-dilutive.

Segment Information—The Company reports segment information in accordance with ASC Topic No. 280 “Segment Reporting.” The Company has one reportable segment.

Recent Accounting Pronouncements

The JOBS Act permits an emerging growth company to take advantage of an extended transition period to comply with new or revised accounting standards applicable to public companies. The Company has elected to use this extended transition period until it is no longer an emerging growth company or until it affirmatively and irrevocably opts out of the extended transition period. As a result, the Company’s financial statements may not be comparable to companies that comply with new or revised accounting pronouncements as of public company effective dates.

Adopted Accounting Standards

In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows: Restricted Cash (Topic 230), or ASU 2016-18. ASU 2016-18 requires that the statement of cash flows explains the change during the period in the total cash and restricted cash. Therefore, amounts generally described as restricted cash should be included with cash when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. This ASU is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. ASU 2016-18 requires retrospective application for all periods presented and as a result the Company has recasted its statement of cash flows for the years-ended December 31, 2018 to reflect the adoption of ASU 2016-18, which was implemented on January 1, 2019.

In May 2017, the FASB issued ASU No. 2017-09, “Compensation—Stock Compensation (Topic 718) Scope of Modification Accounting,” which provides guidance on the various types of changes which would trigger modification accounting for share-based payment awards. In summary, an entity would not apply modification accounting if the fair value, vesting conditions, and classification of the awards are the same immediately before and after the modification. The guidance is effective for annual periods beginning after December 15, 2018, and interim periods within those annual periods. The amendments are applied prospectively to awards modified on or after the adoption date. The new guidance was adopted on January 1, 2019 and this standard did not have a material impact on the consolidated financial statements.

Recently Issued Accounting Pronouncements

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), or ASU 2016-02, which requires lessees to record most leases on their balance sheets but recognize the expenses on their income statements in a manner similar to current practice. ASU 2016-02 states that a lessee would recognize a lease liability for the obligation to make lease payments and a right-to-use asset for the right to use the underlying asset for the lease term. In July 2019, the FASB delayed the effective date for this ASU and will be effective for annual reporting periods beginning after December 15, 2021, with early adoption permitted. While the Company has not completed its evaluation of the impact of adoption of this standard, it does not expect it to have a material impact on its consolidated financial statements.

In February 2018, the FASB issued ASU No. 2018-02, Income Statement—Reporting Comprehensive Income (Topic 220) (“ASU 2018-02”). ASU 2018-02 addresses the effect of the change in the U.S. federal corporate tax rate due to the enactment of the December 22, 2017 Tax Act on items within accumulated other comprehensive income (loss). The guidance will be effective for all annual reporting periods beginning after December 15, 2019, with early adoption permitted. While the Company has not completed its evaluation of the impact of adoption of this standard, it does not expect it to have a material impact on its consolidated financial statements.

On August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement, which changes the fair value measurement disclosure requirements of ASC 820. The amendments in this ASU are the result of a broader disclosure project called FASB Concepts Statement, Conceptual Framework for Financial Reporting—Chapter 8: Notes to Financial Statements. This ASU is effective for all annual reporting periods beginning after December 15, 2019, including interim periods therein. Early adoption is permitted for any eliminated or modified disclosures upon issuance of this ASU. While the Company has not completed its evaluation of the impact of adoption of this standard, it does not expect it to have a material impact on its consolidated financial statements.

In June 2018, the FASB issued ASU No. 2018-07, Compensation—Stock Compensation (Topic 718): Improvements to Nonemployee Share-based Payment Accounting, which expands the scope of Topic 718, Compensation—Stock Compensation, which currently only includes share-based payments issued to employees, to also include share-based payments issued to nonemployees for goods and services. This ASU is effective for all annual reporting periods beginning after December 15, 2019, including interim periods therein. Early adoption is permitted for any eliminated or modified disclosures upon issuance of this ASU. While the Company has not completed its evaluation of the impact of adoption of this standard, it does not expect it to have a material impact on its consolidated financial statements.

In June 2016, the FASB issued ASU 2016-13: Financial Instruments – Credit Losses (Topic 326). This ASU requires the use of an expected loss model for certain types of financial instruments and requires consideration of a broader range of reasonable and supportable information to calculate credit loss estimates. For trade receivables, loans and held-to-maturity debt securities, an estimate of lifetime expected credit losses is required. For available-for-sale debt securities, an allowance for credit losses will be required rather than a reduction to the carrying value of the asset. This standard is effective for interim and annual reporting periods beginning after December 15, 2019. While the Company has not completed its evaluation of the impact of adoption of this standard, it does not expect it to have a material impact on its consolidated financial statements.

Recall

In April 2018, the Company retained outside counsel to assist it in evaluating a safety issue related to certain hair dryers that it imported and sold through its subsidiaries between 2014 and 2018 (the “Xtava Allure Hair Dryer”). The Company had received communications directly from consumers and identified online reviews of overheating or fires associated with these hair dryers. The Company sold approximately 170,000 net units from the introduction of the product in 2015 through its discontinuance in the first quarter of 2018 totaling approximately $6.2 million in net revenue.

In May 2018, the Company’s board of directors approved a voluntary recall of the Xtava Allure Hair Dryer. In June 2018, the Company filed an application for a voluntary recall with the US Consumer Product Safety Commission (“CPSC”) pursuant to Section 15(b) of the Consumer Product Safety Act (“CPSA”). The Company received approval from the CPSC to provide consumers with replacement units and publicly announced the recall on August 15, 2018. The Company had estimated that it would incur approximately $1.6 million in costs related to the recall for procurement, manufacturing, fulfillment and delivery to consumers who apply and qualify for the recall costs. The Company has incurred and settled all but one consumer legal matter related to Xtava Allure Hair Dryer for insignificant amounts. As of December 31, 2019, the Company has incurred $0.1 million in recall costs. In August 2019, the Company received notice that it has materially completed its obligations under the recall program and, as a result, has reversed $1.4 million of the remaining liability pertaining to the program. As of December 31, 2019, the remaining recall liability is $0.1 million.

MidCap Credit Facility and Term Loan

On October 16, 2017, the Company entered into a three-year $15.0 million revolving credit facility (“Credit Facility”) with Midcap pursuant to a Credit and Security Agreement (the “Credit and Security Agreement”). The Credit Facility can be, subject to certain conditions, increased to $30.0 million.

As part of the Credit and Security Agreement entered into on October 16, 2017, the Company also obtained a three-year $7.0 million term loan (“Term Loan”) with MidCap. The Term Loan bears interest at LIBOR plus 9.75% for outstanding borrowings and payments on principal are made on a monthly basis. The maturity date of the Term Loan is October 2020.

On November 23, 2018, the Company exited the Credit Facility with MidCap and entered into a new three-year $25.0 million revolving credit facility (“New Credit Facility”) with MidCap. The New Credit Facility can be increased, subject to certain conditions, to $50.0 million. Loans under the New Credit Facility are determined based on percentages of the Company’s eligible accounts receivable and eligible inventory. The New Credit Facility bears interest at LIBOR plus 5.75% for outstanding borrowings. The Company is required to pay a facility availability fee of 0.5% on the average unused portion of the facility. The New Credit Facility contains a minimum liquidity financial covenant that requires the Company to maintain a minimum of $5.0 million in cash on hand or availability in the New Credit Facility. In 2018, the Company incurred approximately $1.3 million in debt issuance costs which has been offset against the debt and will be expensed over the three years. Unamortized debt issuance costs of $0.7 million, relating to the previous Credit Facility, will be amortized in accordance with the terms of the New Credit Facility. As of December 31, 2018, there was $16.5 million outstanding on the Credit Facility and an available balance of approximately $1.4 million. As of December 31, 2019, there was $23.0 million outstanding on the Credit Facility and an available balance of approximately $0.0 million. The Company was in compliance with the financial covenants contained within the New Credit Facility as of December 31, 2019.

The Company recorded interest expense from the credit facilities of approximately $1.2 million and $2.5 million for the year-ended December 31, 2018 and 2019, respectively, which included $0.4 million and $0.7 million relating to debt issuance costs, respectively.

On the December 31, 2018, the Company repaid the Term Loan with MidCap for $4.9 million as part of the entering into a new term loan with Horizon Technology Finance Corporation, including $0.1 million of a prepayment penalty. The Company expensed the remaining debt issuance costs related to the Term Loan of $0.2 million, including warrants. The Company recorded interest expense from the Term Loan of less than $0.8 million for the year-ended December 31, 2018, which included less than $0.1 million and less than $0.1 million relating to debt issuance costs.

Horizon Term Loan

On December 31, 2018, the Company entered into a new term loan agreement with Horizon (the “Horizon Loan Agreement”). As part of the agreement, the Company obtained a four-year $15.0 million term loan (“Horizon Term Loan”). The Horizon Term Loan bears interest at 9.90% plus the amount by which one-month LIBOR (or, if LIBOR is no longer widely used or available, a successor benchmark rate, which successor rate shall be applied in a manner consistent with market practice, or if there is no consistent market practice, such successor rate shall be applied in a manner reasonably determined by Horizon) exceeds 2.50% for outstanding borrowings and payments on principal are made on a monthly basis. The maturity date of the Horizon Term Loan is January 2023. The Horizon Term Loan contains minimum required EBITDA financial covenants that require the Company to achieve EBITDA of certain amounts based on the amount that the Company is permitted to borrow under the New Credit Facility (the “Revolving Line Indebtedness Cap”). The Horizon Loan Agreement also contains a cash collateral covenant that requires the Company to maintain a cash collateral account with an amount based on the Revolving Line Indebtedness Cap. The term loan payments of principal under the Horizon Term Loan as of December 31, 2019 are as follows:

	Year-Ending December 31
2020	$	3,000
2021		6,000
2022		6,000
2023		—
Thereafter		—
Total term loan payments	$	15,000

In connection with the Horizon Loan Agreement, the Company issued warrants to purchase 76,923 shares of its common stock at an exercise price of $15.60 per share. The warrants are exercisable and expire ten years from the date of issuance. The Company utilized the Binomial option-pricing model to determine the fair value of the warrants. The fair value of the warrants on issuance was $0.9 million, which has been recorded as a debt discount against the Horizon Term Loan.

The Company incurred approximately $1.0 million in debt issuance costs which has been offset against the debt and will expense over the term of the loan.

The New Credit Facility and Horizon Term Loan contain a minimum liquidity covenant that requires the Company to maintain at minimum $5.0 million in unrestricted cash at all times, subject to increases based on amounts drawn. Further, there are additional covenants that, among other things, restrict the ability of the Company and certain of its subsidiaries to (i) incur, assume or guarantee additional indebtedness; (ii) pay dividends or redeem or repurchase capital stock; (iii) make other restricted payments; (iv) incur liens; (v) redeem debt that is junior in right of payment to the notes; (vi) sell or otherwise dispose of assets, including capital stock of subsidiaries; (vii) enter into mergers or consolidations; and (viii) enter into transactions with affiliates. These covenants are subject to a number of important exceptions and qualifications.

As of December 31, 2019, there was $15.0 million outstanding on the Horizon Term Loan and the Company was in compliance with the financial covenants contained within the loan. The Company recorded interest expense from the Horizon Term Loan of $0.0 million and $2.0 million for the year-ended December 31, 2018 and 2019, respectively, which included $0.5 million and $0.3 million, respectively, relating to debt issuance costs.

The Company has operating leases for its offices expiring at various dates through 2020. Rental expense for operating leases was $0.7 million and $0.7 million for the years ended December 31, 2018 and 2019, respectively. The following is a schedule by year of future minimum lease payments required under the operating leases that have initial or non-cancelable lease terms in excess of one year as of December 31, 2019.

Future minimum lease payments under these operating leases consisted of the following as of December 31, 2019:

Inventory Purchases—As of December 31, 2018 and 2019, the Company had $10.2 million and $19.4 million, respectively, of inventory purchase orders placed with vendors waiting to be fulfilled.

Sales or Other Similar Taxes— Based on the location of the Company’s current operations, the majority of sales tax is collected and remitted either by the Company or on its behalf by e-commerce market places in most states within the United States. To date, the Company has had no actual or threatened sales and use tax claims from any state where it does not already claim nexus or any state where it sold products prior to claiming nexus. However, the Company believes that the likelihood of incurring a liability as a result of sales tax nexus being asserted by certain states where it sold products prior to claiming nexus is probable. As of December 31, 2018 and 2019, the Company estimates that the potential liability, including current sales tax payable is approximately $0.7 million and $0.5 million, respectively, which has been recorded as an accrued liability. The Company believes this is the best estimate of an amount due to taxing agencies, given that such a potential loss is an unasserted liability that would be contested and subject to negotiation between the Company and the state, or decided by a court.

Legal Proceedings—The Company is party to various actions and claims arising in the normal course of business. The Company does not believe that the final outcome of these matters will have a material adverse effect on the Company’s condensed consolidated financial position or results of operations. In addition, the Company maintains what it believes is adequate insurance coverage to further mitigate risk. However, no assurance can be given that the final outcome of such proceedings will not materially impact the Company’s condensed consolidated financial condition or results of operations. Further, no assurance can be given that the amount or scope of existing insurance coverage will be sufficient to cover losses arising from such matters.

U.S. Department of Energy

In September 2019, the Company received a Test Notice from the U.S. Department of Energy (“DOE”) indicating that a certain dehumidifier model may not comply with applicable energy-conservation standards. The DOE requested that the Company provide it with several model units for DOE testing. If the Company is determined to have violated certain energy-conservation standard, it could be fined pursuant to DOE guidelines, and this civil penalty may be material to the Company’s consolidated financial statements. The Company intends to vigorously defend itself. The Company has submitted to the DOE testing process, made a good-faith effort to provide necessary notice as practicable, and included in a formal response to the DOE copies of the energy-efficiency report and certification that were issued for the dehumidifier model at the time of production. The Company believes that its products are compliant, and the Company, in conjunction with its manufacturing partner, has disputed the Test Notice received from the DOE. As of the date of the issuance of these financial statements, the Company cannot reasonably estimate what, if any, penalties may be levied.

U.S. Environmental Protection Agency

In September 2019, the Company received notice from the U.S. Environmental Protection Agency (“EPA”) that certain of its dehumidifier products were identified by the Association of Home Appliance Manufacturers (“AHAM”) as failing to comply with EPA ENERGY STAR requirements. For an appliance to be ENERGY STAR certified, it must meet standards promulgated by the EPA and enforced through EPA-accredited certification bodies and laboratories. The Company believes that its products are compliant, and the Company, in conjunction with its manufacturing partner, has disputed the AHAM testing determination pursuant to EPA guidelines. While a resolution remains pending, the Company is not selling or marketing the products identified by the EPA. The Company cannot be certain that these products will eventually be certified by the EPA, and the Company may incur costs that cannot presently be calculated in the event that the Company needs to make changes to the manner in which these products are manufactured and sold.

The Company has temporary differences due to differences in recognition of revenue and expenses for tax and financial reporting purposes, principally related to net operating losses, inventory, depreciation, and other expenses that are not currently deductible or realizable. At December 31, 2019, the Company had approximately $82.9 million of gross federal NOLs which will begin to expire in fiscal year 2034 if unused. The Company also has approximately $46.4 million apportioned state and local NOLs that expire between 2025 and 2035, depending on the state, if not used. The net operating loss (“NOL”) carryforwards for federal and state income tax purposes which, generally, can be used to reduce future taxable income. The Company’s use of its NOL carryforwards is limited under Section 382 of the Internal Revenue Code of 1986, as amended (the “Code”), as it has had a change in ownership of more than 50% of its capital stock over a three-year period as measured under Section 382 of the Code. These complex changes of ownership rules generally focus on ownership changes involving shareholders owning directly or indirectly 5% or more of its stock, including certain public “groups” of shareholders as set forth under Section 382 of the Code, including those arising from new stock issuances and other equity transactions. Some of these NOL carryforwards will expire if they are not used within certain periods.

On December 22, 2017, the Tax Cuts and Jobs Act (the “TCJ Act”) was enacted into law. The TCJ Act provides for significant changes to the Code that impact corporate taxation requirements, such as the reduction of the federal tax rate for corporations from 35% to 21% and changes or limitations to certain tax deductions. The impact of the rate change was $4.0 million for December 31, 2017, which had no tax impact due to offsetting movement in the Valuation Allowance. The reduction in the corporate tax rate under the TCJ Act will also require a one-time revaluation of certain tax-related assets to reflect their value at the lower corporate tax rate of 21%.

The Company regularly assesses the realizability of its deferred tax assets and establishes a valuation allowance if it is more-likely-than-not that some portion of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Due to the Company’s history of net operating losses, the Company believes it is more likely than not its federal, state and foreign deferred tax assets will not be realized as of December 31, 2019.

The Company’s major taxing jurisdictions are New Jersey, New York, Florida, Texas, Pennsylvania, Tennessee, Virginia and California. The Company files a US Consolidated income tax return as well as tax returns in certain foreign jurisdictions. The Company is subject to examination in these jurisdictions for all years since inception. Fiscal years outside the normal statute of limitations remain open to audit due to tax attributes generated in the early years which have been carried forward and may be audited in subsequent years when utilized. The Company is not currently under examination for income taxes in any jurisdiction. The Company may be subject to audits covering a variety of tax matters by taxing authorities in any taxing jurisdiction where the Company conducts business. While the Company believes that the tax returns filed, and tax positions taken are supportable and accurate, some tax authorities may not agree with the positions taken. This can give rise to tax uncertainties which, upon audit, may not be resolved in the Company’s favor. As of December 31, 2018 and 2019, the Company has not recorded any tax contingency accruals for uncertain tax positions.

In addition, the Restated Voting Agreement proxyholder may not be changed unless the Company receives the prior approval of The Nasdaq Stock Market LLC.

Under the Restated Voting Agreement, each of the Designating Parties further agreed not to purchase or otherwise acquire any shares of the Company’s capital stock or other equity securities, or any interest in any of the foregoing.

The Restated Voting Agreement became effective on June 12, 2019 and will continue until the earlier to occur of (a) a Deemed Liquidation Event unless, immediately upon such Deemed Liquidation Event, the Company’s common stock is and remains listed on The Nasdaq Stock Market LLC, or (b) Mr. Yaney’s death.

The Delug Voting Interests include all shares of the Company’s common stock currently held by Mr. Delug, as well as any of the Company’s securities or other equity interests acquired by Mr. Delug in the future. Pursuant to the proxy granted by Mr. Delug, the Company’s board of directors is required to vote all of the Delug Voting Interests in direct proportion to the voting of the shares and equity interests voted by all holders other than Mr. Delug. The proxy granted by Mr. Delug under the Delug Voting Agreement is irrevocable. In addition, the Delug Voting Agreement proxyholder may not be changed unless the Company receives the prior approval of The Nasdaq Stock Market LLC.

Under the Delug Voting Agreement, Mr. Delug further agreed not to purchase or otherwise acquire any shares of the Company’s capital stock or other equity securities, or any interest in any of the foregoing.

The Delug Voting Agreement became effective on June 12, 2019 and will continue until the earlier to occur of (a) a Deemed Liquidation Event unless, immediately upon such Deemed Liquidation Event, the Company’s common stock is and remains listed on The Nasdaq Stock Market LLC, or (b) Mr. Delug’s death. For purposes of the agreement, a “Deemed Liquidation Event” has the same meaning as in the Restated Voting Agreement.

Coronavirus Outbreak

In January 2020, the recent outbreak of a novel strain of coronavirus was first identified that had an unfavorable impact to the Company’s key manufacturing partners. Substantially all of the Company’s products are sourced and manufactured in China, including new products that it expects to launch during 2020. In addition, the Company relies upon its team in Shenzhen for a number of functions relating to product sourcing and development, among other things. The Company has a key manufacturing partner in China that was re-opened as of February 10, 2020 and reached over 90% capacity early in March 2020. This key manufacturer is expected to manufacture over 30% of the Company’s inventory in 2020.

In late March 2020, the outbreak of COVID-19 (coronavirus) caused by a novel strain of the coronavirus has recently been recognized as a pandemic by the World Health Organization, and the outbreak has become increasingly widespread in the United States. COVID-19 (coronavirus) has had a notable impact on general economic conditions, including but not limited to the temporary closures of many businesses, “shelter in place” and other governmental regulations, reduced consumer spending due to both job losses and other effects attributable to the COVID-19 (coronavirus), and there are many unknowns. In light of the uncertainty as to the severity and duration of the pandemic, the impact on the Company’s revenues, profitability and financial position is uncertain at this time.

Operating loss carry forwards		$ 82.9
Operating loss carry forwards expiration year		2034
Description of ownership limitations		The Company’s use of its NOL carryforwards is limited under Section 382 of the Internal Revenue Code of 1986, as amended (the “Code”), as it has had a change in ownership of more than 50% of its capital stock over a three-year period as measured under Section 382 of the Code. These complex changes of ownership rules generally focus on ownership changes involving shareholders owning directly or indirectly 5% or more of its stock, including certain public “groups” of shareholders as set forth under Section 382 of the Code, including those arising from new stock issuances and other equity transactions. Some of these NOL carryforwards will expire if they are not used within certain periods.
