Kevin McCann will retire as chairman and a director of both Macquarie Group and Macquarie Bank, effective 31 March 2016. His successor will be Peter Warne, who has been an independent director on the boards of both ASX-listed Macquarie vehicles since 2007. Warne has had a strong financial services and investment banking career, which has included heading up the financial markets group at Bankers Trust Australia from 1988 to 1999. He has extensive board experience, including directorships with of the Australian Securities Exchange, and the ASX; ALE Property Group; OzForex Group; and NSW Treasury Corporation, among others. DC Payments will mop up yet another automatic teller machine business in Australia, with plans to buy the ATM assets of GRG International. ASX-listed - but long suspended - GRG said it was selling the business to DC Payments Australasia Pty Ltd for an initial payment of A$2 million and a further $2 million payable on renewal and assignment of small number of key contracts. DC Payments will in turn source some ATMs from GRG for its Australian and international operations. Recently appointed OzForex chief executive Richard Kimber continues to make changes at the company. Kimber, who has been in the job since May, appointed a new director of channel marketing, Maria Loyez, in August. Yesterday the company announced that it had a new chief operating officer, former ANZ executive Adam Smith; a new chief technology officer, former News Digital Media CTO Craige Pendleton-Browne; and a new head of people and culture, Kirsten Pollard.
