Brunswick slipped to third place in the global table by deal value, with its deal value falling by 32 per cent, behind Abernathy MacGregor Group.
The league table shake-up was largely due to Brunswick being absent from advising on the huge US$124bn Vodafone sale of its stake in Verizon Wireless in what proved an otherwise muted year for global M&A.
Overall deal volume of US$ 2,215bn was down 3.2 per cent from 2012 (US$ 2,288.8bn) and marginally down on 2011 deal volumes.
The second largest global deal of 2013, the takeover of Heinz by Berkshire Hathaway and 3G Capital, was worth just over one fifth of the Vodafone/Verizon transaction at US$27.4bn.
RLM Finsbury and Sard Verbinnen & Co rounded out the rest of the global M&A adviser top five, with Tavistock Communications climbing from 124th place to sixth due to its work on the Vodafone/Verizon deal.
In Europe, Brunswick again slipped from the top of the table to seventh position, with RLM Finsbury, Maitland and Tavistock topping the table due to their involvement in the year’s biggest deal.
FTI Consulting led the way in terms of global deal volumes, working on 202 transactions, ahead of Brunswick (193) and RLM Finsbury and Sard Verbinnen & Co (both on 115).
