Estimates are used when accounting for amounts recorded in connection with acquisitions, including initial fair value determinations of assets and liabilities and other intangible assets as well as subsequent fair value measurements. Additionally, estimates are used in determining items such as fair value measurements of short-term investments and put right liabilities, impairment of other receivables, long-lived assets, intangible assets and goodwill, useful lives of property, equipment and software, recognition of right-of-use assets and lease liabilities, accrued research and development expenses, cost-to-cost measure of progress for over time performance obligations, variable consideration in collaboration revenue arrangements, valuation of share-based compensation arrangements, deferred tax assets valuation allowances and provision for ongoing litigation. Management bases the estimates on historical experience, known trends and various other assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results could differ from those estimates.</p>
