This index reflects the development of world wide inflation-protected government bonds . The ETF replicates its index using physical replication with sampling, so it contains the most important securities of its reference index.

The yearly average divergence from the index performance (Tracking Difference) since 2009 was 0.25% per year. Therefore, the ETF was slightly more expensive than the TER suggests.
