National Australia Bank Ld 28 August 2006 Monday, 28 August 2006 National Australia Bank comment on Non-Operating Holding Company structure National Australia Bank continues to consider a range of options to optimize its corporate structure to best support the bank's operations domestically and internationally. A non-operating holding company structure is one of the options being considered in response to the changingregulatory environment and its impact on capital and for future flexibility to deliver shareholder value. The National Australia Bank is participating in industry-wide consultation with regulators in relation to the matter. The non-operating holding company structure is widely used in global banking, and the potential application and benefits of this structure were included in the recommendations of the Wallis inquiry. Any such company would continue to be regulated by the Australian Prudential Regulation Authority (APRA). Consideration of various structural options involves a range of complex issues, the analysis, and any subsequent decision on a particular path, are expected to take some time to complete. Once any proposal is sufficiently advanced stakeholders will be consulted. As part of any structural review process, National Australia Bank remains committed to retaining the existing level of credit ratings for the Group.
