"We won't be profitable in 2015 and we won't be profitable in 2016 either," CEO Niall Booker told reporters.

Booker said the bank was continuing to look at all options for a potential initial public offering (IPO).

"Personally I think it will be a wee bit of time before we're ready to IPO. It would be good to be closer to profitability. We continue to review everything," he said.

Booker said there had been "no meaningful discussion" over whether hedge funds that own an 80 percent stake in the bank would be interested in buying the Co-operative Group's remaining 20 percent stake in the bank.
