VIENNA, Nov 6 (Reuters) - Austria's cooperative banking group Oesterreichische Volksbanken AG (OTVVp.VI) reported a half-billion euro third-quarter loss and said it expects more charges and higher risk provisions next quarter.

Bad loan provisions took their toll on Austria's No.4 lender, which posted a 468 million euro ($695 million) pretax loss in the three months to September, more than three times bigger than the loss it suffered in the first six months.

Volksbanken, which already cancelled 2009 coupon and dividend payments on some capital instruments, said it could not promise to make those payouts for the 2010 business year even though it expected a profit for 2010.
