Investments in and Advances to Affiliates [Abstract]
Investments in Unconsolidated Affiliates	Investments in Unconsolidated Affiliates The Company maintains investments in various affiliates that are accounted for as equity method investments, the most significant of which are related to the Company’s merchant alliances. The Company’s share of net income or loss from these investments is reported within income (loss) from investments in unconsolidated affiliates and the related tax expense or benefit is reported within the income tax provision in the consolidated statements of income. The Company reviews its equity method investments each reporting period for indications of an other-than-temporary decline in value, including any significant changes in business relationships with merchant alliances. A decline in value of an equity method investment determined to be other-than-temporary is recorded as a current-period impairment charge within income (loss) from investments in unconsolidated affiliates in the consolidated statements of income. Merchant Alliances The Company maintains ownership interests in certain merchant alliances. A merchant alliance is an agreement between the Company and a financial institution that combines the processing capabilities and management expertise of the Company with the visibility and distribution channel of the financial institution. A merchant alliance acquires credit and debit card transactions from merchants. The Company provides processing and other services to the merchant alliance and charges fees to the alliance based on contractual pricing (see Note 19). The Company’s investment in its merchant alliances was $777 million and $1.2 billion at June 30, 2025 and December 31, 2024, respectively, and is reported within investments in unconsolidated affiliates in the consolidated balance sheets. The Company maintained a 40% ownership interest in the Wells Fargo Merchant Services merchant alliance (“WFMS”), which was accounted for as an equity method investment. The Company acquired its ownership, at fair value, in WFMS through its 2019 acquisition of First Data Corporation. In the third quarter of 2024, Wells Fargo Bank, National Association (“Wells Fargo”) provided the Company with a notice of non-renewal for WFMS. Upon the expiration of the joint venture on April 1, 2025, the Company received a cash payment of $453 million, subject to adjustment upon completion of the contractual valuation and separation process. During the year ended December 31, 2024, the Company recorded a $595 million non-cash impairment as a result of an other-than-temporary decline in the fair value of its equity method investment in WFMS within loss from investments in unconsolidated affiliates, with the related tax benefit of $129 million recorded through the income tax provision, in the consolidated statement of income. The Company recorded an initial pre-tax impairment charge of $570 million in the third quarter of 2024 based upon the Company’s estimate of the fair value of its portion of WFMS, and an additional $25 million pre-tax impairment charge in the fourth quarter of 2024 based upon the expected cash payment as described above. An additional $8 million pre-tax impairment charge was recorded in the second quarter of 2025 in connection with the contractual valuation and separation process. Other Equity Investments The Company also maintains investments, over which it does not have significant influence, in various equity securities without a readily determinable fair value. Such investments totaled $254 million and $250 million at June 30, 2025 and December 31, 2024, respectively, and are primarily included within other long-term assets in the consolidated balance sheets. The Company reviews these investments each reporting period to determine whether an impairment or observable price change for the investment has occurred. To the extent such events or changes occur, the Company evaluates the fair value compared to its cost basis in the investment. Gains or losses from a sale of these investments or a change in fair value are included within other expense, net in the consolidated statements of income for the period. Adjustments made to the values recorded for certain equity securities and net gains from sales of equity securities were not significant during the three and six months ended June 30, 2025, and were $6 million and $27 million during the three and six months ended June 30, 2024, respectively.
