After six years with Bank of Queensland, its managing director and chief executive officer, Jon Sutton, has resigned to focus on his long-term health. The move follows his triple heart bypass operation earlier this year. Sutton said yesterday that instead of leaving BOQ after the emergency surgery back in February, he returned to lead the business throughout 2018 "in the interest of stability". He had been appointed interim CEO in September 2014, following Stuart Grimshaw's surprise exit to run a payday lender in the US.Sutton, who was CEO of Bankwest before being lured to BOQ as its COO in 2012, was confirmed on the top job in January 2015 on the strength of his progress in running BOQ's transformation and digital upgrade programs, which he continued to push.Chairman of BOQ's board, Roger Davis, said the interim CEO would be BOQ's former chief financial officer, Anthony Rose, CEO, who moved into the chief operating officer role in May. Meanwhile a national and international executive search is underway for a permanent replacement for Sutton.  In accordance with the terms of his employment agreement, Sutton will be entitled to nine months' payment in lieu of notice, in addition to his accrued statutory entitlements. Shares allocated under short and long term incentive agreements will vest "in accordance with their terms of grant", BOQ told the ASX.Rose was previously CFO of BOQ's regional rival, Suncorp Bank, a position he held for four years during a period that covered the emergence of and response to the global financial crisis. Prior to that he worked for Citigroup as part of the team that advised Suncorp on its acquisition of Promina in 2007. BOQ said it is in the process of revisiting Rose's remuneration arrangements to reflect the additional duties he will be assuming.  Further details will be released to the market once they are agreed, and will also be included in the Company's 2019 annual report, BOQ has stated.
