The general meaning for the term provision (in accounting particularly) is 'to provide for some expenses which has not arisen now, but may anise in future. It is a cushion and a prudent way of managing the working funds and safeguarding from value erosion or sudden loss.
But when the term is used in relation to banks' annual results and balance sheet reckoning, it has some more specific meaning. It is a fund provision- based on certain statutory and prudent accounting norms – to earmark a certain percentage of the assets (Loans and credits and advances given by banks) and keep apart for any loss or value erosion of assets that may happen in future.
In Banks, there is a risk of borrowers defaulting the loans availed by them. Norms are stipulated to categorize the loans and advances by banks into different categories as per health of the loan( which is based on regularity or irregularity of interest service, repayment, collateral value, utilization etc.) The loans showing unhealthy signals are classified as sub-standard debts of different stage. The healthy loans, where the interest service, repayment, utilisation ,turnover etc. are regular as per norms, are called Standard loans. Even Standard loans also have to be provided for with a minimum percentage provision. The provision increases as per the worsening standard categorisation. Where there is almost no chance of recovery the provision is one hundred percent of the outstanding amount of loan.
As the provision is earmarked from the current year profit, any future recovery on these sub standard assets is directly added to the profit as and when recovered. This helps banks from any sudden shocks of loss and also helps in funds by subsequent recovery. This also helps in 'cleaning; the balance sheet and giving a true picture of the bank's business in relation to capital stability or adequacy.
