</p><p>The Tata Group, company with one of the highest off-shore investors and employers in the UK, is now reviewing its tactics and operation plans in the country due to Britain opting to vote out from the European Union (EU) even as alarmed investors dumped shares of its companies on the Indian bourses.<br><br>Shares of Tata Motors were affected immediately as they went down 8% in a shaken Indian market on Friday, making the group lose Rs 30,000 crore in a single day in market capitalization including Tata Motors, Tata Steel and Tata Consultancy Services.&nbsp;The Tata motor group's automotive unit in the UK, Jaguar Land Rover (JLR), has also taken a hit of $1.47 billion (over 9.5K Crore INR) in the next four years owing to a 10% levy on vehicles sold in EU nations and 4% on imports of components.&nbsp;The Indian conglomerate had their first foot step in UK in 1907 and since 2000, through acquisitions such as Tetley, JLR, Corus (Tata Steel UK), St James Court Hotel, Brunner Mond, among others, it has significant presence in the British country.</p><p>Tata Sons, one of the Tata groups stated "Each company continuously reviews its strategy and operations in the light of developments, and will continue to do so. Access to markets and to a skilled workforce will remain important considerations."<br><br>The diversified enterprise's biggest revenue generating unit in the UK is JLR. JLR, which was purchased in 2008, contributes nearly 90% to Tata Motors profits. It also derives 20% of its sales volumes and sources 35-40% of its components from EU member nations.<br><br>With the UK exiting the EU, the cost of sourcing components from the European states and selling its vehicles in the region will go up as duties and tariffs will come in picture. That said, analysts said JLR will be a major beneficiary as the government will provide incentives to ensure that the UK's automotive industry remains competitive. Also, the depreciation of the pound could positively benefit the company's earnings through exports.<br><br>"We remain absolutely committed to our customers in the EU. There will be a significant negotiating period and we look forward to understanding more about that as details emerge," said JLR.</p><p></p>
