The meeting on demutualisation of bourses, earlier scheduled to be held in Islamabad on November 20 (Saturday), has been postponed. According to Lahore Stock Exchange (LSE) sources here on Thursday, the postponement has been made due to engagements of the Chairman Securities and Exchange Commission of Pakistan (SEC) abroad. The meeting to be attended by chairmen and managing directors of Karachi Stock Exchange (KSE), Lahore Stock Exchange (LSE) and Islamabad Stock Exchange (LSE) was expected to discuss report of the expert committee on demutualisation made public about a month ago.
