Examples of where management makes estimates and assumptions included, but are not limited to the fair value of share-based awards, estimated useful life of long-lived assets, bad-debt allowances, valuation of intellectual property and intangible assets, contingent liabilities, valuation allowance for deferred tax assets, ROU asset impairment, and valuation of non-routine complex transactions, such as recognition of the Earn Out Liability and SPAC Warrants (both as defined below), among others. These estimates are based on information available as of the date of the consolidated financial statements; therefore, actual results could differ from those estimates.</span></div>
