STOXX Europe Sustainability Index* and EURO STOXX Sustainability Index* - KEY FACTS

• The STOXX Europe Sustainability Index* (STX Sustain*) and EURO STOXX Sustainability Index* (ESTX Sustain*) comprise the leading companies in terms of sustainability from Europe and the Eurozone. For both of these indexes there is a composite and a specialized index available with the latter excluding companies that generate revenue from alcohol, tobacco, gambling, armaments or firearms. This set of indexes was first published on 15 October, 2001.
  
• The STX Sustain* tracks the financial performance of the top 20% in terms of sustainability of the companies in the STOXX Europe 600 Index. The ESTX Sustain* is the Eurozone subset of the STX Sustain*.
  
• The STOXX Europe Sustainability Index* and its subsets are reviewed annually and quarterly to ensure that the index composition accurately represents the leading sustainability companies in each of the SAM sectors within the investable universe.
  
• The annual review methodology selects these leading sustainability companies from the investable stocks universe. The resulting changes to the index composition are announced on the annual review date in the first week of September and implemented - after the official closing prices have been determined - on the third Friday of September.
  
• The quarterly reviews reflect changes in the investable stocks universe as well as changes with regard to the number of shares, free float factors and — if applicable — free float cap factors. Quarterly reviews are implemented on the third Friday in March, June, September, and December to become effective on the next trading day.
