The Company bases its estimates on various factors and information which may include, but are not limited to, history and prior experience, expected future results, new related events and economic conditions, which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results could differ materially from those estimates.</span></div>Significant items subject to estimates and assumptions include those related to losses resulting from insurance claims, fair value of financial instruments, goodwill and identifiable intangible assets, leases, indirect tax obligations, legal contingencies, valuation allowance for deferred income taxes, and the valuation of stock-based compensation.<span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Beginning in the middle of March 2020, the outbreak of the coronavirus (“COVID-19”) in the United States, Canada, and globally has impacted the Company’s business.</span><span style="color:#222222;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"> </span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The Company continues to be impacted by COVID-19, but the long-term impact will depend largely on future developments, which are highly uncertain and cannot be accurately predicted, including the duration of the pandemic, new information about additional variants, the availability and efficacy of vaccine distributions, additional or renewed actions by government authorities and private businesses to contain the pandemic or respond to its impact and altered consumer behavior, among other things. The Company has adopted a number of measures in response to the COVID-19 pandemic including, but not limited to, establishing new health and safety requirements for ridesharing and updating workplace policies. The Company also made adjustments to its expenses and cash flow to correlate with declines in revenues including headcount reductions in 2020.

As of the date of issuance of the financial statements, the Company is not aware of any material event or circumstance that would require it to update its estimates, judgments or revise the carrying value of the Company's assets or liabilities, including the recording of any credit losses. These estimates may change, as new events occur and additional information is obtained, and could lead to impairment of long lived assets or goodwill, or credit losses associated with investments or other assets, and the impact of such changes on estimates will be recognized on 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.
