This UCITS-regulated Exchange Traded Fund, the Amundi EUR Overnight Return UCITS ETF Acc, is designed to mirror the performance of its benchmark, the Solactive Euro Overnight Return Index. This index is computed by adding 0.085% to the Euro Short Term Rate (ESTER), which is derived from daily money market transaction data reported by the 52 largest financial institutions in the Eurozone. The European Central Bank (ECB) is responsible for both the calculation and publication of ESTER.
