Bank of Ireland has announced that its chief financial officer, Andrew Keating, is to leave the bank.
Mr Keating, who has worked at the bank since 2004, is set to take up a "senior finance role" in an "international organisation outside the financial services sector", the bank said in a statement.
It said he would step down as CFO and executive director of Bank of Ireland Group by the end of the year, having served in the roles since 2012.
Bank of Ireland said a process to appoint his successor would now begin.
In its statement Bank of Ireland's CEO Francesca McDonagh said Mr Keating had "demonstrated a strong track record of successful financial leadership" during his time as CFO and had "built a market leading finance function" within the lender.
"I wish to acknowledge Andrew's strong support to me in my role as Group CEO and wish him every success in the next phase of his career", she added.
Bank of Ireland chairman Patrick Kennedy said Mr Kenny had "been a key member of the Board and Group Executive team" in recent years and wished him well for the future.
