UPDATE 1-Permira to keep Hugo Boss, ProSieben for years

* Permira as restructured debt on portfolio companies

* Debt restructuring 60 to 70 percent completed

* Evaluating exit possibilities for Cognis exit

(adds details, background)

FRANKFURT, Dec 10 (Reuters) - Permira [PERM.UL] doesn't plan to exit from media company ProSiebenSat.1 (PSMG_p.DE) and fashion label Hugo Boss (BOSG_p.DE) for a couple of years, the German head of the private equity company told Reuters.

Speaking at an event late Wednesday, Joerg Rockenhaeuser said, "We are under no pressure to sell."

Munich-based ProSiebenSat.1 and fashion label Hugo Boss have suffered a decline in revenues as the financial crisis hit the real economy.

Permira's Germany chief said there are several options for exiting out of specialty chemicals company Cognis, adding that "No decision has been made."

The process of debt restructuring is between 60 and 70 percent complete at the companies in Permira's portfolio, Rockenhaeuser said.

"Across the portfolio we have cut debt by a about 4 billion euros ($5.9 billion)," Rockenhaeuser said.
