Public Sector Undertakings (PSUs) are government-owned corporations or state-owned enterprises created by the Government of India to undertake commercial activities on behalf of government. Large infrastructure projects in areas of transport, telecom, energy, fuel, mining, etc are often initiated and managed by the PSUs.

PSUs have been awarded different levels of financial autonomy. These companies are “public sector companies that have comparative advantages”, giving them greater autonomy to compete in the global market so as to “support [them] in their drive to become global giants.”

The level of financial autonomy is currently divided into three categories:

  • Maharatna
  • Navratna
  • Miniratna CPSEs

As on 5 May 2015 there are 7 Maharatna, 17 Navratna and 72 Miniratna CPSE’s.
