A raft of US firms has bagged roles on the $11.3bn (£6bn) acquisition of SunGard Data Systems – securing roles on the biggest leveraged buy-out (LBO) since the legendary bid battle for RJR Nabisco in 1989.

The deal sees a consortium of seven US private equity houses, led by Silver Lake Partners, acquire the financial information group. The consortium instructed Boston’s Ropes & Gray, with New York LBO leader Simpson Thacher & Bartlett advising on financing.
