Should a company not report any of the required data, its exposure is approximated by a ratio of the exports from the country that the company is based in, to the sum of the country’s GDP and imports, which is then multiplied by the global EM exposure of that country. For companies that do not report sales in their home country, revenues in the home region outside of the home country are calculated by dividing the country’s exports to home region by the sum of the country’s GDP and imports. In order to only include companies in the STOXX Europe 600 EM Exposed Index which have a significant part of their revenues from non-developed markets, a final exposure threshold of 33% is set. All companies with a final exposure score that is higher than this are selected as index components, and weighted by a combination of free-float adjusted market capitalization and the exposure factor.
