"As of now, we are watching Brexit but based on our interaction with key customers - financial sector clients as well as in others sectors - post June 23, we don't have any specific caution to report," TCS CEO and Managing Director N Chandrasekaran said.
He said post Brexit events were still "playing out", and added that the strategy would be to "stay very close and take actions, as appropriate".
TCS, India's largest IT services company, has a large exposure to Europe with over 26 per cent of the overall business coming from that market.
For the first quarter ended June 2016, the UK accounted for 14.8 per cent of the revenue, with Continental Europe contributing another 11.5 per cent.

Chandrasekaran said that he had been trying to gauge sentiments during his visit to Europe and his team too had been working closely with clients but added that predicting scenarios was hard.
