This exchange-traded fund (ETF) endeavors to provide investment returns that generally mirror the performance of the Barclays Global Aggregate Treasury Ex USD Issuer Diversified Bond Index (USD Hedged). The fund typically allocates a minimum of 80% of its net assets, along with any borrowed capital used for investment, to a combination of sovereign debt securities and financial instruments designed to mitigate exposure to non-U.S. currencies. The benchmark index itself is constructed to track the performance of high-quality government bonds that are publicly issued in both developed and emerging markets.
