Impax converts sustainable infrastructure fund to ETF

Specialist transition fund manager Impax Asset Management has launched its first exchange-traded fund (ETF). The ETF was a result of Impax converting its Global Sustainable Infrastructure Fund.

In a statement, Impax said the new structure is more flexible and tax efficient. The ETF’s disclosures list its objectives as seeking capital appreciation and income generation aligned with a global energy transition.

“The strategy itself is unchanged. Now in an ETF wrapper that fits more naturally into modern advisory portfolios, clients can take advantage of the same thematic opportunities connected to the transition to a more sustainable economy”, said Robb Ruhr, Impax’s head of portfolio specialists for North America.

In a statement, Impax said the ETF’s portfolio will encompass ‘clean energy and electrification, digital infrastructure, water and waste management, and other critical infrastructure segments’.

This marks the company’s first ETF offering, which Impax says reflects changing client needs.

“We’ve been closely monitoring the growth of the ETF market and believed the Global Sustainable Infrastructure Fund was a natural fit for the structure”, commented Ed Farrington, Impax’s president for North America.

“The move to an ETF is intended to meet the evolving needs of clients and reflect how registered investment advisors are building portfolios, prioritizing tax efficiency, intraday liquidity and operational simplicity, while retaining the benefits of Impax’s active management and investment philosophy”, he explained.

The ETF, that now trades on the New York Stock Exchange, was approved by the Impax board of trustees.
