Latham & Watkins, SJ Berwin, Ashurst and Kirkland & Ellis have picked up roles on Bain Capital's €640m (£557m) disposal of the microconnections unit of French electrical goods manufacturer FCI to private equity fund manager Astorg Partners.

The deal saw Latham advising Bain on French law and M&A aspects of the sale, with Paris private equity partner Thomas Forschbach leading a team that also included M&A partner Denis Criton. Forschbach initially advised Bain on its £724m acquisition of FCI in 2005.

Kirkland's City arm also won a role for longstanding client Bain, with finance partner Neel Sachdev and associate Victoria Cutter advising on financing issues. The US firm had also advised Bain on financing matters connected with its initial acquisition.

SJ Berwin took the lead corporate role for Astorg, with Paris corporate partner Christophe Digoy leading a team which also included tax partner Fanny Combourieu.

Ashurst advised on financing aspects of the deal, with Astorg financing the acquisition through buyout debt of €320m (£278m), and the remainder in equity. Allen & Overy advised the underwriters, which included Goldman Sachs, Nomura and the Royal Bank of Canada.

Sachdev (pictured) commented: "This deal – given its size – is encouraging in a market where many banks are unwilling to provide debt for leveraged deals. It was a complicated carve-out and very rewarding to be involved in."

Microconnections makes flexible tape material used for smart cards such as mobile SIM cards and banking cards. The company is also developing products such as connectors for medical sensors and connectors for LED bulbs.
