I am looking some recent keyword search, people looking for current rate of Infrastructure Bonds but not find out current rate. As per product note these securities listed on NSE & BSE. But exchange not showing rates why ? I am try clear you doubt about this Problems. Why you are not sale these bonds & no trading in this bonds? In a circular to its trading members, BSE said that as per the terms of the issuance of bonds having tax benefits for investors, these bonds are locked in for a period of five years from the date of allotment. “However, it is observed that sell orders have been placed by some of the investors, in spite of these shares being under lock-in, resulting in auction of these trades. Among the 18 bonds listed by the BSE, the earliest lock-in period ends in 2015, while some others are locked in till 2017.
