CBA announced on the ASX this morning that its CFO, Rob Jesudason, has resigned with "immediate effect" to take a position at Hong Kong blockchain company Block.one.
Mr Jesudason replaced long-serving CBA CFO David Craig on 1 July 2017, who retired from his role after 11 years in March 2017.
He has taken up a new role at Hong Kong-based Block.one, where he will be group president and chief operating officer.
Following Mr Jesudason's resignation, CBA has appointed Alan Docherty as acting CFO.
A CBA statement said, "Mr Docherty has been the CFO institutional banking and markets and, since joining CBA in 2003, has held senior finance roles in group finance, group treasury and the business and private bank."
"Previously, he worked in PwC’s Financial Services practice in the United Kingdom, and with Arthur Andersen and Ernst & Young in Sydney."
CBA chief executive Matt Comyn said, "We are making good progress with the renewal of the bank’s executive team and I expect to provide an update on appointments to my leadership team in the coming weeks."
