A flurry of fraudulent activities at Satyam Computer Services, now known as Mahindra Satyam, resulted in financial irregularities worth over Rs 7,855 crore, according to company records.

Once a famed software exporter, former Satyam Computer went into a tailspin after its founder chairman B Ramalinga Raju in January 2009 admitted to cooking up the firm's account for many years.

Even though, he had then admitted to financial fraud to the tune of Rs 7,100 crore, subsequent reports pegged the size of financial irregularities at well over Rs 10,000 crore.

For the first time in two years, Mahindra Satyam today announced its financial numbers for FY'09 and FY'10. The whole process was delayed due to re-statement of accounts after taking into account the fraud committed by the company before Raju's admission last year.

According to the latest details revealed today, specific financial irregularities running into Rs 6,799.5 crore were identified during massive forensic investigations.

Besides, full information is still not available on fraud committed to the tune of over Rs 1,000 crore at the company, including financial frauds committed up to April 1, 2008 and in the subsequent period till Raju's confession in January 2009.

"The forensic investigation revealed that the company had a complex accounting and financial reporting framework, which coupled with multiple non-integrated financial systems enabled the perpetration of financial irregularities," the firm said.

Mahindra Satyam has reported a consolidated loss of Rs 124.60 crore for the year ended March 2010. In the year-ago period, the same was at a whopping Rs 8,176.8 crore in 2008-09.

"The fictitious revenue was recorded by creation of false invoices by circumventing the normal revenue recognition cycle," the company noted.

The fictitious interest income recorded from 2002 to 2008 was at Rs 899.8 crore and fictitious exchange gains from April 2002 to 2008 was at Rs 206.1 crore, documents showed.

As per the available information, the then promoters of Satyam Computer including Raju had shown non-existant cash collections from customers and forged bank statements prepared to support such claims.

The fictitious revenue from April 1, 2002 to Sep 30, 2008 stood at Rs 5,352.8 crore, of which Rs 4,870 crore was translated into fictitious cash and bank balances.
