Sydney, June 22, 2007-Standard & Poor's today announced that it will remove Rinker Group Ltd. (ASX: RIN) from the S&P/ASX indices after the close of trading on Monday, July 2.

The vacancy created by the removal of Rinker Group from the S&P/ASX All Australian 200 will be filled by Mount Gibson Iron Ltd. (ASX: MGX). This will become effective after the close of trading on July 2. "Mount Gibson Iron Ltd. will be the first stock to enter the S&P/ASX All Australian 200 subsequent to the index's launch on June 18, 2007", said Jason Hill, Director and Head of Standard & Poor's Index Services Australia. "The S&P/ASX All Australian 200 does not include foreigndomiciled securities listed on the ASX, and is therefore more fully representative of the characteristics of Australian listed companies".

Rinker Group will not be replaced in the S&P/ASX 50, S&P/ASX All Australian 50, or S&P/ASX 100, each of which currently has an extra security as a result of Asciano Group entering these indices following its recent spin-off from Toll Holdings Ltd.
