The Financial Supervisory Authority in Copenhagen will require pension funds to submit quarterly reports on their alternative investments to track their use of hedge funds, exposure to private equity and infrastructure projects. The decision follows funds’ failures to account adequately for risks in their investment strategies, according to the FSA.

The regulatory clampdown comes as Denmark deals with risks it says are inherent to a system due to be introduced across the European Union in 2016. The new rules will allow pension funds to invest according to a so-called prudent person model, rather than setting outright limits. In Denmark, the approach has proven problematic for the only EU country to have adopted the model, said Jan Parner, the FSA’s deputy director general for pensions.

“The funds are setting up for their release from the quantitative requirements, but the problem is, it’s not clear what a prudent investment is,” Parner said in an interview. “The challenge for European supervisors is to explain to the industry what prudent investments are before the opposite ends up on the balance sheets.”
