Ian Simm, Founder and Chief Executive Officer, Impax Asset Management commented: “Impax’s global investment team continues to identify great opportunities to invest in companies that are benefiting from the transition to a more sustainable economy.  By bringing the mutual funds that we manage in the United States under the Impax brand, the renaming reflects our unified approach to investment world-wide.” 

Impax Asset Management Group plc acquired Pax World Management LLC, investment adviser to the Pax World Funds, in 2018. In North America, Impax manages not only the Pax World family of mutual funds but separately managed accounts, segregated institutional mandates, sub-advised accounts and other investments on behalf of financial intermediaries, consultants, their clients and institutional investors.  All Impax strategies focus on investing in the opportunities arising from the transition a more sustainable global economy, and each fund also integrates environmental, social and governance (ESG) research into the investment process in an effort to better manage risk and deliver competitive long-term investment performance.

“This is a natural next chapter in the long and storied history of the funds”, says John L. Liechty, Chairman of the Board, Pax World Funds. “When it was founded in 1971, Pax World was the first mutual fund in the United States to include environmental and social criteria in addition to traditional financial metrics in company research and portfolio construction. Changing the name to Impax at this time more clearly underscores the funds’ clear focus on the investable opportunities presented by the transition to a more sustainable economy.”

To mark this new chapter and celebrate the heritage of the Pax name, Impax Asset Management has created the Pax Scholarship Program. This will award annual scholarships to three New Hampshire-based educational and non-profit institutions promoting sustainable finance, advancing women and girls, and fostering global peace. These organizations are:

  • The Peter T. Paul College of Business and Economics at the University of New Hampshire – The merit-based scholarship will support students enrolled in the Peter T. Paul College of Business and Economics with a GPA of 3.0 or higher and a demonstrated focus in sustainability and/or sustainable investing.
  • The New Hampshire Women’s Foundation (NHWF) – The NHWF’s mission is to advance social, political and economic opportunity and equality for women and girls through research, education, advocacy, grantmaking and philanthropy.
  • Friends Forever International (FFI) – FFI works with communities around the globe to build the leadership abilities of their youth from diverse backgrounds to tackle local and global issues.
