The company, which is India's fourth largest outsourcer, has already come under criticism from investors and analysts, for its moves on Tuesday last week to diversify into the construction business. It rolled back the decision less than a day later after investors knocked down the price of the company's shares by about 55 percent in trading on the New York Stock Exchange.

Satyam's share price was also down on Wednesday on Indian stock markets by about 15 percent after the World Bank statement.

While the World Bank's decision is a blow to Satyam it will not affect the credibility of other Indian outsourcers, as each outsourcing company is evaluated on its own merits, said an outsourcing analyst who requested anonymity.
