Over the past few weeks, much has been written about former employees of the online commerce company writing to Walmart's board, asking for liquidity on the stock options they were granted 10 to 15 years ago. On October 1, at least eight former senior executives, among them former Myntra CEO Mukesh Bansal and former chief business officer Ankit Nagori, wrote to Walmart chairman Gregory Penner, other board members and Flipkart Group CEO Kalyan Krishnamurthy, seeking a complete exit for all former employees holding vested options.
