The Company evaluates on an ongoing basis its assumptions, including those related to contingencies, income tax uncertainties, incremental borrowing rate for operating leases, fair value of financial assets and liabilities, including fair value of derivatives, fair value and useful life of intangible assets, as well as in estimates used in applying the revenue recognition policy. The Company bases these estimates on historical and anticipated results, trends and various other assumptions that it believes are reasonable under the circumstances, including assumptions as to future events.
