Short Reads - The General Court annulled the EUR 33.6 million fine imposed on banking group HSBC for its participation in the euro interest rates derivatives cartel. Full annulment was granted based on the Commission's failure to provide sufficiently detailed reasoning for the first step of the fine calculation, establishing the value of sales. As the value of sales could not be established in a straightforward way, the Commission used a proxy. When doing so, the Commission needs to properly explain its reasoning to allow the companies fined to understand how it arrived at the proxy.
