A host of firms including national trio Hammonds, DLA Piper and Addleshaw Goddard have secured roles advising on the £162m buyout of software company SSP.

Hammonds advised the management of SSP on the acquisition by H&F Bidco – an investment vehicle owned by funds managed by San Francisco private equity group Hellman & Friedman. The firm fielded a team headed by private equity partner Gregg Davison for the group's management, led by executive chairman David Rasche.

Hammonds has previously advised SSP on deals including its 2006 float on London's Alternative Investment Market, and last year's £43m takeover of Sirius Financial Solutions.
