Key risks of Westpac Subordinated Notes II It is possible that the Notes may trade at a market price below their Face Value. Circumstances in which the market price of the Notes may decline include general financial market conditions, changes in investor perception and sentiment in relation to Westpac, the availability of better rates of return on other securities issued by Westpac or other issuers and the occurrence of a Non-Viability Trigger Event. The market for the Notes may be volatile and less liquid than the market for Ordinary Shares. Holders who wish to sell their Notes may be unable to do so at an acceptable price, or at all, if insufficient liquidity exists in the market for the Notes. There is a risk that Interest will not be paid and that the Face Value will not be repaid because all payments in respect of Notes are subject to the Solvency Condition being satisfied. However, any unpaid Interest will accumulate with compounding (unless Conversion occurs, in which case, accrued but unpaid Interest will not be paid). The Interest Rate will fluctuate (increase and/or decrease) over time with movements in the 90 day Bank Bill Rate. There is a risk that the Interest Rate may become less attractive compared to returns available on comparable securities or investments. The value of Ordinary Shares received for each Note that is Converted upon the occurrence of a Non-Viability Trigger Event may be significantly less than the Face Value of each Note. If for any reason Conversion of Notes is not possible following the occurrence of a Non-Viability Trigger Event (for example, due to applicable law, order of a court or action of any government authority), those Notes will be Written-off and all rights of Holders (including to interest payments and repayment of Face Value) in respect of those Notes will be terminated. Your investment will lose its value and you will not receive any compensation. The price used to calculate the number of Ordinary Shares to be issued on Conversion may be different to the market price of Ordinary Shares at the time of Conversion because the price used is based on the VWAP during the 5 Business days immediately preceding the Conversion Date. Also, the Conversion Number is subject to the Maximum Conversion Number. The value of Ordinary Shares you receive may therefore be significantly less than the value of those Ordinary Shares based on the Ordinary Share price on the Conversion Date. Redemption, Conversion or Write-off may occur in certain circumstances before the Maturity Date, which may be disadvantageous in light of market conditions or your individual circumstances. In the unlikely event of a Winding Up, if the Notes are still on issue, they will rank ahead of Ordinary Shares, equally among themselves and with other Equal Ranking Capital Instruments but behind Senior Creditors, including depositors and all holders of Westpac s senior or less subordinated debt. If there is a shortfall of funds on a Winding-Up to pay the claims of Senior Creditors and holders of other Equal Ranking Capital Instruments, Holders will lose all or some of their investment. Westpac may issue further securities which rank equally with, or ahead of, the Notes. This is a summary of the key risks only.
