Computershare, an Australian securities services provider, has made its largest acquisition with a $115m (€99m) cash deal for New York-based Georgeson Shareholder Communications. If performance goals are met, total value of the deal could rise to $124m.

Dudley Chamberlain, head of investor relations at Computershare said the acquisition was the most significant deal the company had done in recent years. "This puts us into the space in the US market that we need to occupy," he said.
