It is examined if the volume of voluntary disclosure is influenced by transferring a governmental company to private sector. To reveal the impact of privatization on the volume of the voluntary disclosure, a sample of 30 companies transferred from public to private sector since 2003 to 2010, is selected. This sample includes 96 Boards of Directors Reports. The results indicate that the four variables of private ownership, the proportion of state ownership, the proportion of outside board members and leadership structure have significant effects on the level of voluntary disclosure, but  transferring the governmental companies to private sector has not increased the positive effect of the above variables.
