Significant judgments, estimates and assumptions</b></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt 0pt 12pt 0pt;">The preparation of financial statements in conformity with US GAAP requires management to make judgments, estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt 0pt 12pt 0pt;">Future differences arising between actual results and the judgments, estimates and assumptions made by the Company at the reporting date, or future changes to estimates and assumptions, could necessitate adjustments to the underlying reported amounts of assets, liabilities, revenues and expenses in future reporting periods.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt;">Judgments, estimates and underlying assumptions are evaluated on an ongoing basis by management, and are based on historical experience and other factors including expectations of future events that are believed to be reasonable under the circumstances. However, existing circumstances and assumptions about future developments may change due to market changes or circumstances and such changes are reflected in the assumptions when they occur. Significant items subject to estimates include, the recoverable amounts of goodwill and indefinite-lived intangible assets, the useful lives of long-lived assets and finite-lived intangible assets, share-based compensation, share-based continuing employment costs, the determination of lease term and lease liabilities, deferred income taxes, reserves for tax uncertainties, and other contingencies. Accounting for business combinations requires estimates with respect to the fair value of the assets acquired and liabilities assumed. Such estimates of fair value may require valuation methods which use significant estimates and assumptions. At the acquisition of Rouse, we estimated the fair value of the intangible assets acquired, using a valuation method, which required management to make estimates with respect to expected future cash flows and growth rates, gross margins, attrition rates, royalty rates, discount rates, terminal value, and forecast period. The Company based these estimates on historical and anticipated results, industry trends, economic analysis, and various other assumptions that it believes are reasonable, including assumptions as to future events.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt;"><span style="visibility:hidden;"></span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt;">As of December 31, 2020, the Company performed a qualitative assessment of the A&M and Rouse reporting units and a quantitative assessment of the Mascus reporting unit with consideration of the current global economic downturn as a result of COVID-19 and the Company concluded there were no indicators of impairment. </p>
