Hi,
you are in the neck of the moment. If you have more number of LOP in your tenure, you will get the full payment without going into pension scheme. I think its very crucial. Check with HR dept, they will exactly tell you about the status. In our case, we had done this for an employee who has completed 9 years and 3 months. If it is more than 9 yrs and 4 month, pension scheme will automatically come into force and certificate will be issued. So make it fast and hope you will get the entire amount.
