Private equity consists of investors and funds that make investments directly into private companies or conduct buyouts of public companies. Private equity helps companies expand internationally, provides expertise, and creates more employment through business expansion. The largest private equity buyout was KKR's $55.38 billion purchase of RJR Nabisco in 1989. The top 10 private equity firms in India are led by ICICI Venture, Chrys Capital, and Sequoia Capital. Public-private partnerships are used to provide both economic and social infrastructure with the goal of obtaining value for money by treating citizens as customers. Objectives of PPPs include delivering government services efficiently, stimulating private sector growth, and serving public and business interests.
