Annual results released on October 28 by National Australia Bank (NAB) highlight the impact of the bank's A$5.5 billion (US$4.0 billion) equity raising in May. NAB also expects to add approximately 50 basis points more to a common-equity tier-one (CET1) ratio which had reached 10.2 per cent by the end of September this year, ahead of events which will reduce the position significantly.
