The Iranian government envisioned a large privatization program in the Fifth Five-Year National Development Plan (2010-2015), aiming to privatize about 20 percent of the state-owned firms each year.
Under the present interpretation of the Article 44 of Iran's Constitution, hundreds of state-owned companies have been privatized.
In May, Tasnim reported that the shares of 337 state-run companies are prepared to be transferred to the private sector by the current Iranian calendar yearend.
The Iranian Privatization Organization transferred above $419 million worth of the state-run shares to the private sector during the last week of Farvardin, the first month of the Iranian calendar year 1396, (April 17-23).
