The OTCEI allows listing of small and medium sized companies. The first issue listed on the OTCEI was in July 1992. The minimum issued share capital required of a company that wants to be listed on OTCEI is Rs.3 million and the maximum Rs.250 million.
Listing on OTCEI is advantageous to companies because of the high liquidity of these securities, which is a result of compulsory market making, improved access and speed of transactions resulting from the extensive network of electronically interlinked counters.
Companies engaged in investment, leasing, finance, hire purchase, amusement parks etc., and companies listed on any other recognized stock exchange in India are not eligible for listing on OTCEI. Also, listing is granted only if the issue is fully subscribed to by the public and sponsor.
