MELBOURNE (Standard&Poor's CreditWire) July 5, 2001--Standard&Poor's today affirmed its double-'A' long-term and single-'A-1'-plus short-term counterparty credit ratings on National Australia Bank Ltd. (NAB) following the announcement by NAB of a US$450 million (A$568 million after tax) provision against the mortgage servicing rights of Homeside Lending Inc. (single-'A'-plus/Stable/'A-1'-plus).
