In the accompanying consolidated financial statements, estimates are used for, but not limited to, the valuation of assets (including intangibles assets, goodwill and long-lived assets), liabilities, consideration related to business combinations and asset acquisitions, revenue recognition (including variable consideration), estimated selling prices for performance obligations in contracts with multiple performance obligations, reserves for claims and performance-based arrangements, credit losses, depreciable lives of assets, impairment of long-lived assets, stock-based compensation, deferred income taxes and valuation allowance, contingent liabilities, purchase price allocation in taxable stock transactions and useful lives of intangible assets.</span></div>
