Important note on these presentation slides, including the use of non-ifrs financial information This document is a visual aid accompanying a presentation to analysts by the Group Chief Executive Officer and the Executive Director Finance on 9 May 2013. It is not intended to be read as a stand-alone document. It contains select information, in abbreviated or summary form, and does not purport to be complete. It is intended to be read by an analyst audience familiar with National Australia Bank Limited and its March 2013 Half Year Results, and to be accompanied by the verbal presentation. This document should not be read without first reading the National Australia Bank Limited March 2013 Half Year Results, which has been lodged with the Australian Securities Exchange at the same time as this document and is available at www.nab.com.au. The verbal presentation to analysts places emphasis on cash earnings measures of the Group s performance. NAB uses cash earnings for its internal management reporting purposes and considers it a better reflection of the Group s underlying performance. Accordingly, as a visual aid to that presentation, information in this document is presented on a cash earnings basis unless otherwise stated. Cash earnings is calculated by excluding some items which are included within the statutory net profit attributable to owners of the Company. It is not a statutory financial measure and is not presented in accordance with Australian Accounting Standards nor audited or reviewed in accordance with Australian Auditing Standards. The definition of cash earnings, a discussion of non-cash earnings items and a full reconciliation of the cash earnings to statutory net profit attributable to owners of the company is set out on pages 2-8 of the National Australia Bank Limited March 2013 Half Year Results. The Group s financial statements, prepared in accordance with the Corporations Act 2001 (Cth) and Australian Accounting Standards, and reviewed by the auditors in accordance with Australian Auditing Standards, are included in Section 5 of the 2013 Half Year Results Announcement. Note: The inclusion of percentage changes in brackets in this document indicates an unfavourable movement on a prior comparative period. This document is not intended to be relied upon as advice to investors or potential investors and does not take into account the investment objectives, financial situation or needs of any particular investor. These should be considered, with or without professional advice, when deciding if an investment is appropriate. This document contains certain "forward-looking statements". The words "anticipate", "believe", "expect", "project", "forecast", "estimate", outlook, "likely", "intend", "should", "could", "may", "target", "plan" and other similar expressions are intended to identify forward-looking statements. Indications of, and guidance on, future earnings and financial position and performance are also forward-looking statements. Such forward-looking statements are not guarantees of future performance and involve known and unknown risks, uncertainties and other factors, many of which are beyond the control of the Group, which may cause actual results to differ materially from those expressed or implied in such statements. There can be no assurance that actual outcomes will not differ materially from these statements. 2
