Hope everyone remember the failure of ONGC follow offer that happened last year. So this is a indirect way of forcing / cheating public i.e., tax benefit for you, but capital will be eaten by Government.
This is not open to Demat account holders but direct investors. With the withdrawal of ELSS, such investments should be allowed through mutual funds as such small investors will feel more secure. This will facilitate ease in investing as well as encashment after 3 years than dealing direct with the Govt agencies.
