We base our estimates on historical experience, and other assumptions we believe to be reasonable under the circumstances, which together form the basis for making judgments about the carrying values of assets and liabilities. Assumptions and estimates used in preparing our consolidated financial statements include those related to the determination of allowances for credit losses, the capitalization and estimated useful life of internally developed software, contingent liabilities, useful lives of property and equipment, the incremental borrowing rate used to determine the present value of lease payments, the valuation and recognition of share-based compensation, the valuation of the convertible notes and warrant liability, the valuation and estimated useful lives of acquired intangible assets, uncertain tax positions, accrued liabilities, and the recognition and measurement of current and deferred income tax assets and liabilities. Actual results could differ from these estimates and could have a material adverse effect on our consolidated financial statements.</span></div>

In the event our counterparties do not fulfill their obligations, we may be exposed to risk. The risk of default depends on the creditworthiness of the counterparty. Default of a counterparty in equities and options trades, which are facilitated through clearinghouses, would generally be spread among the clearinghouse's members rather than falling entirely on us. It is our policy to review, as necessary, the credit standing of each counterparty.</span></div>
