The ETF replicates its index using full physical replication, so it contains all the securities of its reference index. The ETF's earnings (dividends) are automatically reinvested (accumulated). The fund company Xtrackers claims a total expense ratio (TER) of 0.25% per year. The yearly average divergence from the index performance (Tracking Difference) since 2015 was -0.01% per year.
