WIP provides exposure to international ex-US inflation-protected debt securities. Both developed and emerging market sovereigns are fair game, and the fund takes concentrated country positions at times (capped at 23% at rebalance). Issues are weighted by market value and rebalanced at the end of each month. Note: Prior to May 31, 2018 the underlying index for WIP was Citi International Inflation-Linked Securities. Prior to Feb 12, 2016 the underlying index was a similar index from Deutsche Bank. The fund changed its name each time to reflect the corresponding index.
