In June, Fitch Ratings downgraded the company’s long-term issuer default rating (IDR) and senior unsecured rating by six notches to BBB from its previous rating of AA.

The ratings agency cited concerns about the increased likelihood that demands from the US government and federal authorities over the disaster which were likely to result in a ‘legally supportable move against the company.’

Analysts at Fitch said the potential financial impact on BP is wide-ranging and warned investors to expect Long-term litigation related damages.

The cost of civil fines if BP were to be found guilty of gross negligence or willful misconduct would be in the region of US $2 billion – US $8 billion, according to the ratings agency.
