Westpac will have paid out 86 per cent of this year's profit as a dividend, thanks to a second "special dividend" of 10 cents for the year from the bank in the second half.The Australian Prudential Regulation Authority's recent caution on banks paying special dividends and returning capital does not seem to have fazed the Westpac board.Gail Kelly, the bank's chief executive, told investors at a briefing to announce the bank's 2012/13 results yesterday that "our common equity tier-one ratio… is sector leading and well above our own target range of 8 to 8.5 per cent."A 10 cent special dividend would amount to about 10 basis points of capital, so you can see after that we've plenty of head-room to absorb the Lloyds acquisition and still remain comfortably above our target range and be comfortably ahead of our peers."Kelly also addressed the forthcoming framework for assessing domestic systemically important banks, or D-SIBs, that APRA has said will be released by the end of the year."We know that it's going to come into place from the 1st of January 2016," Kelly said."What we don't know yet is how much it will be. We don't know anything about the implementation timetable yet."In Canada, for example - a market that's similar to ours - the implementation timetable will be over three years, starting from the 1st of January 2016, and there are some elements of capital measurement that haven't yet been defined… in a relative sense, we're very well placed."Phil Coffey, the chief financial officer, said: "When you look at us from a global perspective in terms of the capital that we're holding, we feel great about that.""Increasingly I think it's recognised by global institutional investors as well just how strongly capitalised Australian major banks are, and Westpac in particular. "How we move into accommodating the D-SIB, is something that we'll all have a greater idea of in the next few months, and what impact that might have on ROE likewise."
