The following information is added to the section entitled “Portfolio Managers – Compensation Structure”:

Compensation – Mr. McDevitt: Compensation consists of fixed remuneration in the form of a base salary and variable (at risk) performance pay in the form of an annual profit share allocation. All employees at Macquarie are also eligible for superannuation contributions.

Fixed remuneration takes into consideration the role of individuals and market conditions. Remuneration is reviewed on a yearly basis in March / April and takes effect from July 1 of that year.

Aggregate staff profit share is linked to Macquarie’s profitability and return on ordinary equity, with the allocation of individual profit share being based on factors including contribution to profit, use of capital, funding and risk. Macquarie operates profit share retention arrangement for employees meeting certain pay thresholds, to ensure an appropriate balance between short and longer-term incentives. Retained amounts from 2009 onwards are invested in the Macquarie employee retained equity plan. The use of equity for employee remuneration strengthens the alignment between the interests of staff and shareholders and Macquarie’s ability to attract and retain high quality staff.
