The iBoxx € Overall is designed to measure the performance of investment grade, EUR-denominated bonds from sovereign, sub-sovereign, corporate and collateralized issuers, without restrictions on issuer domicile. Sovereign and sub-sovereign bonds require a minimum amount outstanding of EUR 1 billion, while corporate, collateralized and covered bonds require EUR 500 million for new issues and EUR 1 billion for legacy bonds. Bonds must have remaining time to maturity of at least one year at rebalancing. Only fixed-rate bonds whose cash flows can be determined in advance are eligible, excluding T-Bills and money market instruments.
