The convertible bond from Thomson Multimedia, the French media and consumer group, has increased to €600m ($523m) after Goldman Sachs and SG exercised the greenshoe, the option to sell more paper.

The two banks were joint global co-ordinators, lead managers and bookrunners of a combined €1.6bn equity and convertible bond sale which was sold in two hours on Monday. The equity offer was covered four times and the convertible bond 18 times. The convertible was priced at the tight end of the bookbuilding range with the highest conversion premium of 35% and the lowest coupon, or interest payment, of 1%.
