Aflac, the number one provider of supplemental insurance in the United States¹, announced that the company has retained its membership on theFTSE4Good Index. FTSE, a leader in global indices, has included Aflac as a member of this prestigious index since 2011. Aflac is one of 159 U.S. Companies currently included on the list.

The FTSE4Good Index Series objectively measures the performance of companies that meet globally recognized corporate responsibility standards, according to the FTSE website. For inclusion, eligible companies must meet criteria requirements regarding sustainability, human rights, supply chain labor standards, countering bribery and climate change.

"Aflac strives to be a good neighbor in our community by making sustainability and social responsibility a cultural priority," Aflac's Chairman and CEO Dan Amos said. "We are proud of our membership on the FTSE4Good Index because it validates our belief that being a good corporate citizen makes good business sense, and it is also the right thing to do."

To compile the index, FTSE works with Ethical Investment Research Services (EIRIS) and its network of international partners to research company corporate responsibility performance. Researchers use a variety of mechanisms to access the most up-to-date data including annual reports, information on company websites, and questionnaires to aid in determining if a company meets the criteria for inclusion.

In addition to FTSE4Good membership, Ethisphere magazine also included Aflac on its list of the World's Most Ethical Companies for the seventh consecutive year in 2013. Aflac is one of 159 United States companies and 722 globally on the FTSE4Good Index as of March 29, 2013.
