Accounting estimates

There are many accounting estimates in the financial statements, e.g.
allowances for receivables, depreciation of property, plant and
equipment, provisions, etc.

Accounting estimates are inherently risky because they are about the
future, are often not supported by documentary evidence and therefore
accuracy may not be able to be verified.
