Significant estimates and assumptions reflected in the financial statements include revenue recognition, allowance for doubtful accounts, stock-based compensation, inventory valuation, accrued warranty obligations, fair value of debt derivatives and convertible notes, fair value of acquired intangible assets and goodwill, useful lives of acquired intangible assets and property and equipment, incremental borrowing rate for right-of-use assets and lease liability, probable loss recovery of tariff refunds, legal contingencies, and tax valuation allowance. These estimates are based on information available as of the date of the financial statements; therefore, actual results could differ materially from management’s estimates using different assumptions or under different conditions.</span></div><div style="margin-bottom:6pt;margin-top:6pt;text-align:justify;text-indent:27pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The worldwide spread of the COVID-19 virus has resulted in a global slowdown of economic activity which decreased demand for a broad variety of goods and services, including from our customers, while also disrupting sales channels and marketing activities for an unknown period of time and may continue to create significant uncertainty in future operational and financial performance. The Company expects this to have negative impact on its sales and its results of operations. In preparing the Company’s consolidated financial statements in accordance with GAAP, the Company is required to make estimates, assumptions and judgments that affect the amounts reported in its financial statements and the accompanying disclosures. Estimates and assumptions about future events and their effects cannot be determined with certainty and therefore require the exercise of judgment. As of the date of issuance of these financial statements, the Company is not aware of any specific event or circumstance that would require the Company to update its estimates, judgments or revise the carrying value of its assets or liabilities. These estimates may change, as new events occur and additional information is obtained, and are recognized in the consolidated financial statements as soon as they become known. Actual results could differ from those estimates and any such differences may be material to the Company’s financial statements.</span></div>
