It will suit the new chief of the bank to have what appears to be a bad set of results (headline loss of £1.3 billion) and then next year the accounts will look so much better and a nice bonus will come his way.
When i used to look at accounts I always felt things such as the 'provision for bad debt' figure could be manipulated and make a significant difference to whether a company shows a profit or a loss. Yes, the accounts are audited, but maybe it's the same accountants/auditors that failed to spot the huge problems with Britannia when Coop Bank took them over
