Besides a USD 55.5 million global management system (GSM) project, where Satyam was the key vendor, WHO had awarded three other contracts totaling nearly USD 400,000 to the Indian firm, a WHO spokesperson said from Geneva.

"Satyam is bidding for one future contract, unrelated to GSM," the official said.

Responding to queries on whether the fraud at Satyam would affect the IT firm's dealings with WHO, the spokesperson said, "WHO is reviewing carefully its current contractual agreements with Satyam and possible contingency arrangements for completion of GSM project work, in the event that Satyam were no longer able to perform."

Satyam has been debarred by World Bank, while it has been suspended from the vendor database of the UN Secretariat.

The company founded by Ramalinga Raju, who is in jail pending probe into an accounting fraud disclosed by him, also came in for criticism from the Comptroller and Auditor General of India for its tardy implementation of a project at WHO.

CAG, which was external auditor to WHO, flagged a number of risks associated with the execution of the GSM project.

"Until now, Satyam has carried out technical activities for 21,131 (man) days and thereby may claim a total of USD 28.6 million, exceeding the contracted amount by USD 1.4 million," CAG Vinod Rai said in the audit report submitted to WHO's Health Assembly way back in May 2008.

The USD 55.5 million project was initially targeted to go live in September 2007, but was given its first extension until December 2007, then a second until March 2008 and a third until June 2008, the auditor said. However, even the extended deadline has been missed.

Satyam was contracted as the main system integrator of the project. The contract of USD 27.2 million to Satyam included performance of services for 15,000 man days.

Taking note of the auditors' concerns and those related to "corporate difficulties" at Satyam, the WHO's Executive Board, at a meeting on January 16, said that there was no indications at present of any disruptions in services to WHO.
