Such estimates include, but are not limited to: the useful lives of assets; assessment of the recoverability of long-lived assets; goodwill impairment; standalone selling price of material rights and the period of time over which to defer and recognize the consideration allocated to the material rights; allowance for doubtful accounts; liabilities relating to transaction losses; stock-based compensation; and accounting for income taxes. Management bases its estimates on historical experience and on various other assumptions that management believes to be reasonable under the circumstances.

The Company maintains its cash balances with large, high-credit quality financial institutions and other payment companies. At times, such deposits may be in excess of federally insured limits. The Company has not experienced any losses on its deposits. Credit risk on trade receivables is limited as a result of the large size of the Company’s client base as well as a large portion of payments made using pre-authorized credit cards. The Company performs ongoing credit evaluations of its clients and maintains allowances for potential credit losses. For any receivables that are deemed not collectible, losses are recorded when probable and estimable. These losses, when incurred, have been within the range of the Company’s expectations.</span></div><div style="margin-bottom:6pt;text-align:justify"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">One client accounted for more than 10% of trade and client receivables as of December 31, 2021.
