Moody's affirmed Fidelity National Information Services Inc.'s Baa2 senior unsecured rating and P-2 short term rating, following the company's announcement of its deal with payments processor Worldpay Inc.

The ratings outlook is stable.

According to the rating agency, the acquisition of Worldpay is credit positive because it combines industry leaders in bank payment processing and merchant acquiring and will lead to a stronger business profile than that of stand-alone Fidelity.
