Prime Minister Narendra Modi will on Wednesday inaugurate the Golden Jubilee Year Celebrations of the Institute of Company Secretaries of India (ICSI). Originally set up as not-for-profit organisation on October 4, 1968, the institute was in 1980 converted into a statutory professional body under an Act of Parliament — The Company Secretaries Act 1980. Several Cabinet Ministers and top officials of the Corporate Affairs Ministry and Finance Ministry are expected to attend the celebrations, sources said. This event assumes significance as it comes close on the heels of the government action of de-registering over 2.1 lakh dormant/shell companies and disqualifying over one lakh directors as part of a clean up of the corporate system and tackling the menace of shell companies.
