The interim condensed consolidated financial statements of the Company have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X as promulgated by the Securities and Exchange Commission. Accordingly, the financial statements do not include all of the information and footnotes required by GAAP for complete financial statements and should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Reports on Form 10-K for the year ended December 31, 2022.

The interim condensed consolidated financial statements are unaudited; however, in the opinion of management, all adjustments, consisting of normal recurring items, considered necessary for a fair presentation of the results of the interim periods have been included. Dollar amounts are reported in millions, except per share data and other key metrics, unless otherwise noted

Basis of consolidation

Basis of ConsolidationThe condensed consolidated financial statements include the accounts of the Company, its wholly-owned subsidiaries, other entities in which the Company has a controlling financial interest and those variable interest entities (“VIE”) where the Company’s wholly-owned subsidiaries are the primary beneficiaries. Assets and liabilities of VIEs and their respective results of operations are consolidated from the date that the Company became the primary beneficiary through the date the Company ceases to be the primary beneficiary. The Company applies the equity method of accounting to investments where it is able to exercise significant influence, but not control, over the policies and procedures of the entity and owns less than 50% of the voting interests. These investments are initially measured at cost and subsequently adjusted for the Company’s proportionate share of earnings and losses in the investee. Investments in certain companies over which the Company does not exert significant influence are recorded at fair value, or at cost and updated for observable price changes upon election of measurement alternative, at the end of each reporting period. Intercompany balances and transactions on consolidated entities have been eliminated.
