Privatization Administration chairman Metin Kilici said the public offering was aimed at encouraging small scale investors and workers and the amount of shares on offer could be extended to 17.5 percent depending on the response to the IPO.
However, Kilic would not be drawn on whether the price range for the sale, set between 3.90 to 4.70 lira, was too high or too low.
With the sale, the Turkish Treasury will retain between 27.5 and 30 percent of the land line monopolys shares.
