Global Payments, an electronic payments processor, is buying smaller rival Accelerated Payment Technologies (APT) from private equity firm Great Hill Partners for USD413 million. Utah-based APT provides payment services to small and medium-sized merchants in industries such as medicine, pharmacy and auto. Global Payments says that in fiscal year 2013 it anticipates the deal to have a minimal impact on its revenues, as it already processes most of APT's transactions. However, it expects the purchase to boost revenues thereafter.
