Provisioning is a mechanism to counter bad assets. Under provisioning, banks have to set aside or provide funds to a prescribed percentage of their bad assets. The percentage of bad asset that has to be ‘provided for’ is called provisioning coverage ratio. The provisioning coverage ratio is the percentage of bad assets that the bank has to provide for (keep money) from their own funds –most probably from profit.
For example, if the provisioning coverage ratio is 70% for a particular category of bad loans, banks have to set aside funds equivalent to 70% those bad assets out of their profits. Assets of a bank means loans they have given and investment they have made. If the loans are not coming, there should be provisioning for such bad debts. The assets are classified by the RBI in terms of their duration of non-repayment (NPA, doubtful asset etc.).
