Subsequent Events [Abstract]
Subsequent Events	Subsequent Events On January 16, 2019, the Company announced that it had entered into a definitive merger agreement to acquire First Data in an all-stock transaction for an equity value of approximately $22 billion as of the announcement. The transaction is expected to close during the second half of 2019, subject to customary closing conditions, regulatory approvals and shareholder approval for both companies. In connection with the definitive merger agreement, the Company entered into a bridge facility commitment letter pursuant to which a group of financial institutions committed to provide a 364-day senior unsecured bridge term loan facility in an aggregate principal amount of $17 billion for the purpose of refinancing certain indebtedness of First Data and its subsidiaries on the closing date of the merger, making cash payments in lieu of fractional shares as part of the merger consideration, and paying fees and expenses related to the merger, the refinancing and the related transactions. On February 15, 2019, the Company entered into a new term loan credit agreement with a syndicate of financial institutions pursuant to which such financial institutions have committed to provide the Company with a senior unsecured term loan facility in an aggregate principal amount of $5.0 billion, consisting of $1.5 billion in commitments to provide loans with a three-year maturity and $3.5 billion in commitments to provide loans with a five-year maturity. The aggregate principal amount of the commitments under the term loan credit agreement have replaced a corresponding amount of the commitments in respect of the bridge facility in accordance with the terms of the bridge facility commitment letter. As a result, there are now $12.0 billion in bridge facility commitments remaining. The Company expects to replace these remaining commitments with permanent financing in the form of the issuance of debt securities prior to the closing of the acquisition of First Data. The availability of loans under the term loan facility is subject to the satisfaction or waiver of certain conditions that are substantially consistent with the conditions to the funding of the bridge facility, including (i) the closing of the acquisition substantially concurrently with the funding of such loans, (ii) the absence of a material adverse effect with respect to First Data since January 16, 2019, (iii) the truth and accuracy in all material respects of certain representations and warranties, (iv) the receipt of certain certificates, and (v) the receipt of certain financial statements. Loans drawn under the term loan facility will be subject to amortization at an annual rate of 5% for the first two years and 7.5% thereafter (with loans outstanding under the five-year tranche subject to amortization at an annual rate of 10% after the fourth anniversary of the commencement of amortization), with accrued and unpaid amortization amounts required to be paid on the last business day in December of each year. Borrowings under the term loan facility will bear interest at variable rates based on LIBOR or on a base rate plus, in each case, a specified margin based on the Company’s long-term debt rating in effect from time to time. The Company is also required to pay a ticking fee that will accrue on the aggregate undrawn commitments under the term loan facility at a per annum rate based upon the Company’s long-term debt rating in effect from time to time. The term loan credit agreement contains affirmative, negative and financial covenants, and events of default, that are substantially the same as those set forth in the Company’s existing revolving credit facility, as amended as described within Note 6.

On January 16, 2019, the Company announced that it had entered into a definitive merger agreement to acquire First Data in an all-stock transaction for an equity value of approximately $22 billion as of the announcement.
