BWZ provides global ex-US exposure to fixed-rate local currency sovereign bonds. The fund holds investment grade debts so it may heavily tilt towards Japan and Eurozone countries, but emerging markets are welcome as well. The global Treasurys will have a rating of Baa3/BBB- or higher with maturities between 1-3 years. As such, BWZ will have exposure to both interest-rate and currency risk. The fund is rebalanced monthly and will employ a sampling strategy, which means it will only hold a subset of securities that will mimic the risk and return characteristics of the Underlying Index.
