"There's been very little marking down of (private) assets," said Con Keating, head of research at Brighton Rock Group, an insurance company for pension schemes. "No-one knows where the next big blow-up for pensions will come from," said Henry Tapper, founder of pension market analysis group AgeWage. He said heavy selling of commercial property and private equity stakes by pension schemes is raising questions over private capital valuations. "It's the right approach to obviously put some scrutiny on private market valuations." But in deals where private equity firms and investors buy and sell portfolios of investments, assets are being valued at less.
