  • "Clifford Chance is particularly active in IPOs, but also demonstrates strength in rights offerings, convertible bonds, block trades and equity derivatives. Employee shares schemes and stock option schemes are another area of focus. US securities specialist Alex Bafi and Aline Cardin, an expert in French and international securities offerings, head the practice. Jointly with regulatory specialist Frédérick Lacroix the team advised Société Générale as shareholder and ALD as issuer on ALD's €1.2bn Rule 144A IPO on the Euronext Paris, assisting with both French and US law issues. On the block trade side, recent highlights include advising Altrafin on the sale of 8.4% of Altran's share capital by way of accelerated bookbuilding. Olivier Plessis made counsel and Julien Rocherieux was promoted to partner."
