It will include checking also of the mechanical calculations, comparison along with estimates made in prior times and consideration of management's approval process.
Wherever in the case of contingent liabilities, subsequent events 'crystallize' the liability there will be no requirement to review management's processes or requirement independent calculation. The auditor will usually test the estimation of the calculations, asses the assumptions created as the court is 90% probable to find in our favour compare estimates along with those made in previous duration and ensure about the estimate is in accordance along with the auditor's information of the business and the other audit evidence obtained.
