Standard & Poor’s Announces The Treatment Of The SRG Spin-Off From Macquarie Infrastructure Group In The S&P/ASX 50

Standard & Poor’s, the leading provider of equity indices in Australia, announces the inclusion of Sydney Roads Group (ASX: SRG) in the S&P/ASX 50 and all related indices. This addition is a result of an in-specie distribution of SRG by Macquarie Infrastructure Group (ASX: MIG) to all shareholders on a basis of 1 for 3. Due to the lag between the ex date (July 17, 2006) and the date the SRG shares start trading (July 24, 2006) Standard & Poors will add a cash security, SGRX, to the S&P/ASX 50 and all related indices after the close of trade on Friday July 14, 2006.
