The iBoxx USD Liquid Emerging Markets Sovereigns Mid Price TCA Index is designed to measure the transaction cost-adjusted performance of USD-denominated sovereign debt issued by the 20 largest and most liquid emerging market central governments or central banks, with a minimum amount outstanding of USD 500 million. Bonds must have a minimum time to maturity of two years at inclusion and a remaining time to maturity of at least 1.25 years at rebalancing.
