Skadden, Arps, Slate, Meagher & Flom and Linklaters have taken the lead advisory roles on Japan’s Mitsui Sumitomo Insurance’s (MSI) proposal to purchase UK-based insurer Amlin for 3.47 billion pounds ($5.3 billion).

MSI, one of MS&AD Insurance Group Holdings’ major subsidiaries, specialises in the non-life insurance segment of the market, including the property, automobile, casualty, marine and aviation sectors. Amlin, listed on the London Stock Exchange, is a global underwriter of insurance for commercial companies and reinsurance for insurance firms.

Skadden is advising MSI, led by London-based corporate partners Scott Hopkins and Robert Stirling, and Tokyo-based Mitsuhiro Kamiya. Partners Mark Darley and Tim Sanders in London as well as Simon Baxter in Brussels are handling the banking, tax and antitrust aspects of the deal, respectively.

Linklaters’ London-based team is led by partner Aedamar Comiskey, with support from fellow partners William Buckley, Gillian Chapman and Nicola Mayo.

Sullivan & Cromwell is advising Goldman Sachs as the lead financial advisor, while Clifford Chance is representing the bank on its role as lender.
