Over the years, Allen & Overy has been involved in many developments in the legal field. Such work has included advising on the first hostile takeover in the City of London and acting for S. G. Warburg & Co. The firm arranged the first Eurobond (issued by Italian motorway group Autostrada) in the 1960s. The Eurobond transaction significantly diversified Allen & Overy's practice from a purely commercial into commercial and financial firm. Through the 1970s the firm's finance and corporate practice grew in the UK and internationally.
