Global credit rating agency Fitch Ratings on Wednesday revised Goldman Sachs Group's rating outlook to 'Negative' from 'Stable' considering the recent legal problems and regulatory challenges faced by the company.

"Goldman's franchise and market position are potentially vulnerable to scrutiny by stakeholders, and like peers, may be affected by the industry's regulatory evolution," the rating agency said in its statement. It considered that the regulatory challenges faced by the company may hurt Goldman's revenue stream.

Meanwhile, as said by Fitch Ratings, after the US market watchdog Securities and Exchange Commission (SEC) filed civil fraud charges against the financial giant, the US Attorney's Office was also preparing to conduct a probe against the firm's mortgage trading activities.

In fact, some of the non-US regulators have also shown intentions of carrying out investigations against Goldman's mortgage transactions, Fitch said in its statement.

However, the World number three credit rating agency also clarified that attempts to get rid of the problems, which are being talked about Goldman at present, may help the company revive its risk profile by some extent, but it would end up decreasing the company's revenue and profitability.
