Audit Tesla’s warranty account, accounting homework help

• Based on the examination of Tesla’s financial statements and notes you will perform a risk assessment and identify a significant (qualitative and quantitative characteristics) account (e.g. Goodwill/Allowances/Valuation for DTA/etc.). For the selected account determine which assertions are relevant (completeness, existence, accuracy, valuation, obligations and rights, presentation) and provide the following:
  • Controls tested for test of design and conclusion (include sample sizes any how they were determined)
  • Controls tested for operating effectiveness and conclusion (include sample sizes any how they were determined)
  • Substantive tests performed and conclusion (include sample sizes any how they were determined)
  • Final audit opinion over controls
  • Final audit opinion over financial statements

Note1: Only one account needs to be selected but if there is another account that goes hand-in-hand you should be consistent (e.g. Goodwill + Impairment)

Note 2: If the substantive tests showed any errors (you can be creative and give them deficiencies on controls or a qualified opinion as long as you detail why).
