Birley will report to Mark Ibbotson, executive vice president of global clearing at NYX, and work alongside Declan Ward, executive director & head of NYSE Liffe Clearing.
Subject to regulatory approval, NYSE Liffe Clearing will be expanded in 2013 to become NYSE Clearing – a fully integrated Central Counterparty, serving multiple markets.
Ibbotson said that Birley brings with him a wealth of clering experience where he has led the development of several successful businesses.
"Patrick is as excited as we are about the clearing opportunities that lie ahead, and about collaborating with our customers – many of whom he knows already – as we roll out pioneering, value-added clearing solutions," Ibbotson said.
