Kushal Pal Singh constructed numerous earthquake-proof office buildings, apartments, shopping malls and leisure facilities in Gurgaon. Under his tenure, as the Chairman of DLF, the company went for an initial public offering (IPO) in 2007 and made about US$2.24 billion, one of the largest IPOs in India. Market capitalization of the company increased to $24.5 billion, making Singh and his family one of the richest clans in the world. Jack Welch, the former chairman and CEO of General Electric, said in an interview that Singh was one of the initiators for GE's entry into India.
