NEW DELHI, AUG 10 (PTI): There is no proposal under consideration for restoration of the Old Pension Scheme (OPS) due to its unsustainable fiscal liability on the Government exchequer, Minister of State for Finance Pankaj Chaudhary said on Monday. Replying to another question, Chaudhary said the restoration of OPS in the States falls exclusively under State policy discretion. “However, the Comptroller and Auditor General (CAG), in its recent State Finance Audit Reports, has highlighted the fiscal implications of reversion to OPS by the States. The National Pension System (NPS) is a defined contribution-based scheme which was introduced for Central Government employees (except armed forces) joining service on or after January 1, 2004,” he said. The total assets under management (AUM) under NPS for Central Government employees as on July 7 is Rs 3.65 lakh crore.
