Information technology services provider Tata Consultancy Services (TCS) Ltd has told analysts that it could suffer, as usual, weakness in business and decline in margin in the third quarter of current fiscal.

The country's largest IT services provider said its third quarter would be a usual one, with weak business and decline in margin, due to lesser working days.

The three months through December usually record weak business weak quarter for the industry due to more holidays and lesser working days.

However, the company assured that the company would not report any sudden negative surprises for the quarter in review.

In the first quarter of the current financial year, the company enjoyed a volume growth of 5.3 per cent; while in the second quarter, it grew 5 per cent.
