The fine has been levied for Prudential's failure to inform the FSA that it was seeking to acquire the Asian arm of AIG at an appropriate time, in breach of FSA Principles and UKLA Listing Principles.  Prudential should have notified the FSA of its intentions at the earliest opportunity, so that the regulator could decide whether to approve or reject the deal on regulatory grounds.  But according to an FSA news release, Prudential failed to reveal its intentions to the FSA even when quizzed on its plans for expansion in Asia.  The delay in notification, which finally came after a press leak, meant that the FSA was forced to rush its analysis of the proposed deal.

In addition to the fine, the FSA also censured Prudential CEO Tidjane Thiam, although it stopped short of finding any lack of fitness or propriety on his part.
