National Stock Exchange of India Ltd. will pursue plans to raise up to $1 billion via a public listing after Chief Executive Chitra Ramkrishna's decision to step down last week, said four sources familiar with the matter. Two of those sources said the initial public offering (IPO) plans are now likely to move faster after Ramkrishna resigned over differences with the board about the IPO process. All four sources declined to be named because they have not been authorized to discuss the matter publicly.

"She did not want to be the face of the IPO to the outside world," one source told Reuters. "She had told a lot of people that she wasn't keen on continuing."
