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 in the form of pre-authorized credit cards. The Company performs ongoing credit evaluation 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.</font></div><div style="line-height:120%;padding-bottom:8px;padding-top:0px;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Two</font><font style="font-family:inherit;font-size:10pt;"> clients each accounted for more than 10% of trade and client receivables as of </font><font style="font-family:inherit;font-size:10pt;">December 31, 2018</font><font style="font-family:inherit;font-size:10pt;"> and </font><font style="font-family:inherit;font-size:10pt;">2017</font><font style="font-family:inherit;font-size:10pt;">.

Where neither vendor-specific objective evidence nor third-party evidence of selling price exists, the Company is required to use its best estimate of selling price to allocate arrangement consideration on a relative basis to each element. At the inception of arrangements which do not include subscription services, as there is no fixed consideration to be allocated, a relative fair value allocation is not required. In the instance the multiple-element arrangements include subscription services, the only fixed consideration relates to the subscription services, which is a separate unit of accounting. The fixed consideration is allocated only to the subscription services at inception, as all other fees in the arrangements are contingent on certain activities being performed as stated above.</font></div></div>

Such estimates include, but are not limited to, the useful lives of assets; assessment of the recoverability of long-lived assets; goodwill impairment; allowance for doubtful accounts; liabilities relating to transaction losses; the valuation of warrants; 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 evaluates its estimates, assumptions, and judgments on an ongoing basis using historical experience and other factors and revises them when facts and circumstances dictate. Actual results could materially differ from these estimates.</font></div></div>
