You are right r2del. At the moment, we have only one annuity plan available - LIC's Jeevan Akshay VI.

This is due to the new pension guidelines issued by IRDA - the Indian Insurance Regulator in 2010-11
1- As per the IRDA regulations (which came into force in September 2010) on pension products mandating a minimum annual guarantee of 4.5 per cent. Following that, unit-linked pension plans disappeared from the market and no new unit-linked pension products were introduced after that. Only pension plans on the traditional platform were available.
2- Consequently, in the revised guidelines, IRDA has withdrawn the 4.5 per cent guaranteed returns, but maintained there must be some guarantee element with the plan either by way of offering positive returns on premiums paid during the period of the contract, or assured maturity benefits.
3- IRDA had also asked all insurers to withdraw all existing pension plans by January 1, 2012.
4- Since November, 2011, IRDA has not approved any new pension products.

However, none of the new policies that insurance companies have filed for approval have found favour with IRDA. Apparently, the regulator has rejected all of them.
