Key information on getting started with the PRI:



Organisations can become a signatory if they fall under one of these three categories:

  • Asset owners representing the holders of long-term retirement savings, insurance and other assets. Examples include pension funds, sovereign wealth funds, foundations, endowments, insurance and reinsurance companies and other financial institutions that manage deposits. This is our principal category of signatory.
  • Investment managers managing or controlling investment funds as a third-party, serving an institutional and/or retail market. Investment managers who are still raising funds, rather than actively managing assets, can sign pre-emptively as provisional signatories.[1]
  • Service providers  (professional service partners) offering products or services to asset owners and/or investment manager who demonstrate a commitment to providing, developing and promoting services that support a clients’ implementation of the principles.

If you have a query about your organisation’s category, please email us

The PRI Board reserves the right to determine which category is most appropriate. 

Annual fee

The annual signatory fee is payable each April and is scaled according to each signatory’s category.

The PRI Board has approved a moderate increase in signatory fees for 2023. We are simultaneously taking active steps to reduce our own operating costs, but this increase is necessitated by inflationary pressures across our key markets.

Fees are calculated based on signatories’ latest AUM (for asset owners and investment managers) or number of investment staff (for service providers). For new signatories that have not reported yet, their fees will be calculated based on the figures provided when they signed up as a PRI signatory.

The PRI is a not for profit organisation and signatory fees and other revenue are spent on delivering value to our diverse signatories, through opportunities for learning and development, sharing best practices, collaborative engagement and driving responsible investment.

Asset owners

The fee is scaled according to the assets your organisation manages.

Asset owners headquartered in a country classified by the IMF as an emerging market or developing economy can email us to apply for a fee discount.
