Permira, the private equity group, has issued capital call letters to raise $917.8m (£622.8m) from its investors for its acquisition of NDS, the set-top box company, in the first test of its revised fundraising structure.
The letters come less than a month after Permira agreed to allow 18 of its investors to reduce their commitments to its €11.1bn (£9.9bn) fund, shrinking it to €9.6bn, after learning that some of them faced liquidity problems and could default on capital calls.
