Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts in the interim consolidated financial statements and notes thereto. Significant estimates and assumptions reflected in the financial statements include, but are not limited to, the estimated average playing period of payers that we use for revenue recognition, useful lives of property and equipment and intangible assets, accrued liabilities, income taxes, the fair value of assets and liabilities acquired through business combinations, contingent consideration obligations, the discount rate used in measuring our operating lease liabilities, the interest rate used in calculating the present value of the initial liability component of our convertible senior notes, stock-based compensation expense and evaluation of recoverability of goodwill, intangible assets and long-lived assets and as necessary, estimates of fair value to measure impairment losses. Actual results could differ materially from those estimates. Recent Accounting Pronouncements Issued But Not Yet Adopted In August 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2020-06, “Debt – Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in Entity’s Own Equity (Subtopic 815-40)”, which simplifies the accounting for convertible instruments by reducing the number of accounting models and requiring that a convertible instrument be accounted for as a single liability measured at amortized cost. Further, the ASU amends the earnings per share guidance by requiring the diluted earnings per share calculation for convertible instruments to follow the if-converted method, with use of the treasury stock method no longer permitted. The ASU is effective for fiscal years beginning after December 15, 2021, with early adoption permitted, but no earlier than fiscal years beginning after December 15, 2020. The ASU allows either a modified retrospective method of transition or a fully retrospective method of transition, with any adjustments recognized as an adjustment to the opening balance of retained earnings. The Company is currently assessing this standard’s impact on its consolidated financial statements, but does anticipate a material adjustment to the carrying amount of the liability and equity components of our convertible senior notes upon adoption and the Company will adopt on January 1, 2022. In October 2021, the FASB issued ASU 2021-08, “Business Combinations (Topic 805) – Accounting for Contract Assets and Contract Liabilities from Contracts with Customers”, which requires that an acquirer recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606, as if it had originated the contracts. Prior to this ASU, an acquirer generally recognizes contract assets acquired and contract liabilities assumed that arose from contracts with customers at fair value on the acquisition date. The ASU is effective for fiscal years beginning after December 15, 2022, with early adoption permitted. The ASU is to be applied prospectively to business combinations occurring on or after the effective date of the amendment (or if adopted early as of an interim period, as of the beginning of the fiscal year that includes the interim period of early application). The Company is currently assessing this standard’s impact on its consolidated financial statements.

Recent Accounting Pronouncements

Issued But Not Yet Adopted

In August 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2020-06, “Debt – Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in Entity’s Own Equity (Subtopic 815-40)”, which simplifies the accounting for convertible instruments by reducing the number of accounting models and requiring that a convertible instrument be accounted for as a single liability measured at amortized cost.

The ASU allows either a modified retrospective method of transition or a fully retrospective method of transition, with any adjustments recognized as an adjustment to the opening balance of retained earnings. The Company is currently assessing this standard’s impact on

its consolidated financial statements, but does anticipate a material adjustment to the carrying amount of the liability and equity components of our convertible senior notes upon adoption and the Company will adopt on January 1, 2022.
