Guus Warringa, former general counsel at Dutch asset manager APG, has joined international investor law firm Grant & Eisenhofer (G&E). 

During his seven-year tenure at the €424bn asset manager, Warringa helped European pension funds to challenge the European Market Infrastructure Regulation (EMIR), as well as controversial European Commission proposals to levy a financial transaction tax (FTT).

On behalf of APG’s main client, the €356bn civil service pension fund ABP, Warringa also played a leading role in lawsuits against Goldman Sachs, JP Morgan, Morgan Stanley, Deutsche Bank and Credit Suisse over the alleged mis-selling of collateralised debt obligations prior to the financial crisis.

All of these cases were settled in 2013.

Jay Eisenhofer and Stuart Grant, G&E’s co-founders and managing directors, said Warringa was a “tremendous addition” to the company.

“His extensive experience and vigorous activism on behalf of institutional investors will be an incredible assets to our client base,” they said.

Warringa said the law firm provided an “excellent platform” to continue his work on behalf of pension funds and other institutional investors, which have become “much more vocal and active in recent years”.

“Joining G&E provides me with the opportunities to further support that process and strengthen the investors’ possibilities,” he added.

Prior to joining APG, Warringa served as general counsel at Euronext Amsterdam.

He has also held senior international positions within the NYSE Euronext group.

Warringa started his career in private practice as a mergers and acquisitions lawyer.

He holds a law degree from Leiden University and a Masters degree from Cambridge University.

US-based G&E represents institutional investors from across the globe in securities class actions, derivatives lawsuits and financial litigation matters.
