In a week that has been dominated by bank regulation announcements and European government debt, Credit Suisse's equity capital markets team has managed the year's first large block trade and picked up an eye catching mandate to manage an unusual bank liability management exercise.

The Swiss bank acted alongside JP Morgan on a block trade disposing of 25m shares in Danish bioscience firm Christian Hansen held by French private equity firm PAI Partners. The sale of the shares, worth around $525m based on Wednesday's closing price, leaves the private equity firm's holding vehicle Financière Star 1 with 51.6m shares, or a 37.4% in the company, according to a company announcement.
