Concept:A provision is an amount kept aside for a known expense or loss whose exact value is not yet certain.
Explanation:Businesses create a provision when an expense is likely to arise but the precise amount cannot be fixed.
Provisions help match expected future costs with the current accounting period.
A reserve is an appropriation of profit and is not meant for an uncertain expense.
A liability is an amount owed, not necessarily an amount set aside.
A prepayment is an expense already paid in advance, not an uncertain amount.
Therefore, the amount set aside for an expense of uncertain value is called a provision.
