NEW YORK--(BUSINESS WIRE)--NYSE Euronext today announced an enhanced methodology for the NYSE Arca Gold Miners Index (GDM), the preeminent index covering the gold mining industry. For the first time ever, the index will include non-U.S. listed companies and set a minimum market capitalization requirement of $750 million for component companies. The changes will be enacted at the next index rebalance effective before the open on Monday, September 23, 2013.

“These changes are indicative of the growing demands by clients who want exposure to a global universe of larger-cap gold mining companies.”

“The NYSE Arca Gold Miners Index is the leading benchmark covering the gold mining industry for the community of market participants and exchange traded product issuers on our exchange,” said Dwijen Gandhi, managing director, Global Index and Exchange-Traded Products. “These changes are indicative of the growing demands by clients who want exposure to a global universe of larger-cap gold mining companies.”

The NYSE Arca Gold Miners Index is a modified market capitalization weighted index comprised of publicly traded companies primarily involved in the mining of gold and silver in locations around the world.

Below are the key changes to the NYSE Arca Gold Miners Index methodology:

• access to non-U.S. listed companies, ensuring component diversity and international exposure;
• new index components must have a minimum of $750 million in market capitalization;
• prioritization of U.S. cross-listings, American Depository Receipts and Global Depository Receipts for international companies;
• implementation of a buffer zone around the $750 million market capitalization and other trading requirements to reduce turnover during quarterly rebalances.

The rebalance and methodology changes will result in the following companies being added to or deleted from the NYSE Arca Gold Miners Index effective for Monday, September 23, 2013:
