What is the difference between MOD balance and available balance?

MOD balance: MOD means Multi Option Deposit – in MOD balance, the surplus funds in the savings a/c gets transferred to a fixed deposit a/c. Therefore, the holder earns more interest rate in this case.
Available balance: It is the fund in the savings a/c of the account holder. However, the total amount in an account holder’s credit is the sum of both MOD and available balance.
