In: Accounting
The engagement to be undertaken for all the 3 items stated above would be an assurance engagement itself. The type of engagement does not change on the level of assurance required by the management.
There are mainly two types of assurances, reasonable assurance and limited assurance. However, a third type of assurance that exists is absolute assurance. However it is irrelevant in such circumstances as no accountant/auditor can provide absolute assurance no matter how much evidence is possessed by him.
In the first two cases, where the level of assurance required is high and important for the management, the auditor should try to deliver reasonable assurance and nothing more than that. A reasonable assurance is one where the auditor / accountant agrees that the evidence obtained meets or fulfills certain criteria which is necessarily required by the auditor/accountant in order to issue a reasonable assurance.
In the third case, since the management is willing to have less work done on it, the concerned auditor/ accountant can choose to provide limited assurance, however the fact that he is going to provide only limited assurance should be conveyed to the concerned management in writing and should be done only after obtaining their approval on the same.
I hope the above solution is what you were looking for. For any further queries or doubts in the solution, please feel free to drop a comment. Please do leave a positive feedback, Thank you :)
