Rohini Nilekani, wife of Infosys cofounder Nandan Nilekani, disclosed Friday that she has recently sold 577,000 shares out of the 8 million shares that she holds in the outsourcer. The sale reduced her stake marginally from 1.41% to 1.31% which is still worth close to $370 million. The funds from the share sale, amounting to $27 million pre-tax, will be deployed in various charities in the areas of water, education, environment and governance that Nilekani supports.
