The S&P/ASX iBoxx Australian Fixed Interest Diversified 0+ Index measures the performance of investment grade, AUD-denominated bonds issued by government, sovereign, semi-government and corporate issuers in Australia. The index is equally weighted across two defined issuer sectors—the Corporates & Covered and Government & Semi-Governments & Sovereigns—and across three major maturity segments in the Government & Semi-Governments & Sovereigns issuer sector—0-5 years, 5-10 years and 10+ years. Bonds must have a minimum amount outstanding of AUD 2 billion for Australian Government Securities, AUD 250 million for Australian State Governments and Territories and AUD 100 million for other issuers. Bonds must have a minimum time to maturity of 18 months at issuance and be clearable through Austraclear.
