Clydesdale Bank received approval from its board to issue up to £387 million of new, tier one capital at a general meeting on July 1, the Herald Sun reported. National Australia Bank, Clydesdale's owner, is yet to actually invest all the additional capital, however. Clydesdale will have a capital base of more than £1.04 billion once NAB has made this investment, or around four times the capital support required before the financial crisis.
