With various hurdles, including legal ones, hampering its merger with Tech Mahindra, the board of Satyam Computer Serviceshas extended the validity of the scheme of amalgamation by six months till September 30.

Bombay High Court has already approved the scheme, but the Andhra Pradesh High Court has not.

As per the swap ratio announced in March last year, the merger would be at two shares of Tech Mahindra for 17 shares of Satyam.

Satyam shareholders had opposed the ratio citing valuation errors. Some had also filed a petition in court challenging the scheme.

Some of the creditors, too, had opposed the merger claiming that Satyam had to refund their funds.

Besides, a group of entities allegedly belonging to Satyam’s founder B Ramalinga Raju has been claiming that about `1,230 crore borrowed from it was routed into Satyam.

However, the new management of Satyam led by the Mahindras has been maintaining that there was no evidence of any such funds flowing into Satyam.

In fact, officials of the Registrar of Companies informed the court that they could not clear the merger proposal for want of additional information.

An external auditor was asked to study the books of Satyam yet again. While the auditor has submitted his report, the official liquidator is yet to approve the report and report it to the court.
