Goldman Sachs says it expects to be hit by more shareholder lawsuits and regulatory investigations in addition to those that have already been announced since the Securities and Exchange Commission accused it of fraud last month.

“We anticipate that additional putative shareholder derivative actions and other litigation may be filed,” the US firm – which has a large wealth management operation – was reported by the Financial Times as saying in a quarterly regulatory filing yesterday.

Goldman Sachs has been accused of selling collateralised debt obligation securities to investors without informing them that some of the financial instruments inside the CDO had been chosen by renowned hedge fund investor, John Paulson. Paulson intended to short-sell these securities and has made huge profits by successfully predicting the collapse of the US sub-prime mortgage market.

The Wall Street firm said last week that it was already facing lawsuits from shareholders questioning the board’s independence and faulting it for failing to disclose that it had received notification of a pending enforcement action. Law firms have told this publication that suits were likely against Goldman Sachs.

Goldman is in settlement talks with the SEC while prosecutors are considering a criminal probe. It is also being investigated by the UK’s Financial Services Authority.

The bank said on Monday that if it was unable to secure waivers from regulators or to resolve the SEC action, the results could bring “collateral consequences”, including the possibility that it would no longer be able to function as a broker-dealer or provide advisory services to US mutual funds.

Goldman has vigorously denied any wrongdoing. The affair has tarnished the reputation of a firm that had, until the charges were brought, been seen as one of the great victors of the financial crisis.

Wealth managers have told this publication that they expect to take business from Goldman Sachs, as some of that firm’s clients will be concerned. The firm has declined to comment on this matter when contacted. In the past, it has declined to discuss its wealth management business operations.
