The number and value of private equity buyouts in the third quarter slumped on the back of a global credit crunch, according to new data, but deals below $100m (€70.5m) appeared unaffected by the fallout.

Globally, $132bn (€93bn) of financial sponsor-backed deals were announced in the latest three months, a drop of 67% on the second quarter and less than a fifth of this year's total, said Dealogic.
