MUMBAI, May 9 (Reuters) - India's national pension scheme offers "exceedingly good" returns of 9-12%, compared to most benchmarks, a top official at the pension fund regulator said on Tuesday.
The National Pension Scheme, adopted in 2004, has recently come under criticism for inadequate returns, leading to a few state governments reverting to an earlier pension plan considered fiscally unviable.
States that have decided to move back to a so-called old pension scheme include Rajasthan, Jharkhand, Chattisgarh, Himachal Pradesh and Punjab.
The old pension scheme offered assured returns to pensioners without any contribution from the employees, which made it fiscally unsustainable for the government.
Economists warned that the return to a scheme with assured returns could hurt India's attempts to improve government finances and reduce debt.
