Actual results could materially differ from management estimates using different assumptions or under different conditions. </span></div>Significant accounting estimates made by the Company include useful lives of property and equipment, valuation of deferred taxes, valuation of inventory, carve-out of condensed financial statements including the allocation of assets, liabilities and expenses, incremental borrowing rate used in calculating lease obligations and right-of-use asset, and fair value of common stock used to determine stock-based compensation expense prior to the merger with Kensington, and other inputs used to value stock-based compensation awards.
