Significant items subject to such estimates and assumptions include professional services revenue, valuation allowance for deferred tax assets, stock-based compensation, useful lives of property and equipment, valuation of inventory, useful lives of intangible assets, accrued liabilities, incremental borrowing rate for leases, and the valuation of the private warrants. The Company bases its estimates on historical experience and also on assumptions that it believes are reasonable.
