On an on-going basis, management evaluates its estimates, including those related to amounts recognized for bad debts and inventory obsolescence which requires estimates of sales forecasts and other marketplace considerations, internal use software which requires estimates of whether the costs incurred meet the criteria for capitalization based on the stage of the projects, the portion of MSE billings related to professional services, the recoverability of goodwill and intangible assets which require estimates of future cash flows and discount rates, lease liability which requires estimates of incremental borrowing rate and the expectation of exercising lease renewal periods, income taxes, contingencies and litigation, and estimates of credit spreads for determination of the fair value of derivative instruments. Management bases its estimates on historical experience, available market information as applicable, and on various other assumptions that are believed to be reasonable under the circumstances at the time they are made. Under different assumptions or conditions, the actual results will differ, potentially materially, from those previously estimated. Many of the conditions impacting these assumptions and estimates are outside of the Company’s control.</p> <p style="font-family: "Times New Roman", Times, serif; font-size: 10pt; margin: 0pt; text-align: justify; text-indent: 36pt;"> </p>

Cash equivalents consist of deposits with major commercial banks, the maturities of which are <em style="font: inherit;">three</em> months or less from the date of purchase. With respect to accounts receivable, the Company performs periodic credit evaluations of the financial condition of its customers and typically does <em style="font: inherit;">not</em> require collateral from them. The counterparty to any forward foreign exchange contracts is a major commercial bank which management believes does <em style="font: inherit;">not</em> represent a significant credit risk. Management assesses the need for allowances for potential credit losses by considering the credit risk of specific customers, historical trends and other information.</p> <p style="font-family: "Times New Roman", Times, serif; font-size: 10pt; margin: 0pt; text-align: left; text-indent: 36pt;"> </p>
