"iShares Core Global Aggregate Bond UCITS ETF EUR Hedged (Acc)" is an exchange-traded, Euro hedged investment fund (ETF). It refers to the Bloomberg Global Aggregate Bond Index. This index reflects the development of stocks . The ETF replicates its index using physical replication with sampling, so it contains the most important securities of its reference index. The ETF's earnings (dividends) are automatically reinvested (accumulated). The fund company iShares claims a total expense ratio (TER) of 0.10% per year. The yearly average divergence from the index performance (Tracking Difference) since 2018 was 0.55% per year. Therefore, the ETF was more expensive than the TER suggests. Besides, the yearly tracking differences had strong variations, so their average value is not a very reliable measure.
