Private equity-related activity in the global equity capital markets is at a half-year record after a six months in which buyout firms have taken advantage of buoyant conditions to exit over $70bn worth of investments.

Financial sponsor-backed deals priced so far in 2013 total $74.5bn, according to Dealogic, up 91% on the first six months of 2012. That accounts for 19% of all ECM activity so far this year, the highest percentage on record, according to the data provider.
