Moody's has affirmed ACI Worldwide Inc.'s corporate family rating of Ba3, its probability of default rating of Ba3-PD and its speculative grade liquidity of SGL-2.

The ratings outlook remains stable.

The corporate family rating reflects the company's stable revenues, which are driven by a base of recurring revenues and long-term software licensing contracts, according to Moody's. The outlook reflects the rating agency's expectation of low-single-digit organic growth in the company's revenues.
