The accounting estimates that require management’s most difficult and subjective judgments include:</span><span style="font-family:inherit;font-size:10pt;"> leases, including determining the incremental borrowing rate; income taxes, including the accounting for uncertain tax positions; purchase price allocations for business combinations, valuation of the acquired intangibles purchased in a business combination; valuation of goodwill and intangible assets; stock-based compensation; and fair value of financial instruments.</span><span style="font-family:inherit;font-size:10pt;"> The Company evaluates its estimates and judgments on an ongoing basis and revises them when necessary.

The Company reduces credit risk by placing its cash and cash equivalents with major financial institutions with high credit ratings. At times, to the extent eligible, such amounts may exceed federally insured limits. The Company believes that minimal credit risk exists with respect to these investments due to the credit ratings of the financial institutions that hold its short- and long-term investments. In addition, funds receivable settle relatively quickly, and the Company’s historical experience of losses has not been significant.</span></div>
