Skadden Arps Slate Meagher & Flom has advised insurance and financial products giant Generali Group on two major bond issues worth a combined value of £1.3bn – the biggest piece of work the firm's London office has done for the client.

Skadden London finance partner James Healy led the team on the deal which saw Generali issue two bonds worth €1.25bn (£827m) and £495m. Generali will use the proceeds to repay outstanding debt under a financing agreement for the acquisition of Italian insurer Toro Assicurazioni.

Healy said: "Generali has been one of our major clients for some time. It is a significant fundraising for Europe's third-largest insurance company and a great deal for us to do exclusively out of London."

Although the firm has advised on a number of major transactions for Generali – including advising its parent company Assicurazioni Generali on its $12.7bn (£6.45bn) acquisition of insurance group Istituto Nazionale delle Assicurazioni – this is the first bond issue the firm has done for the group.

Clifford Chance Milan capital markets partner Filippo Emanuele advised joint lead managers and bookrunners HSBC, JP Morgan, Mediobanca and UBS.
