Hellman & Friedman , the megabuyout firm which has backed companies including Nielsen NV and Getty Images, is in the final stages of wrapping up its latest fund, which has attracted investor demand well in excess of its $10.25 billion hard cap, according to investors.

Hellman & Friedman joins a select group of large-cap firms such as Silver Lake and Apollo Global Management that have been able to shrug off lingering uncertainty about the viability of large buyout pools and ended up with more interest than they could accommodate. Two investors said that the firm cut back the size of their desired allocation to the new fund due to excess demand.
