Consult Paragraph 67 of PCAOB Auditing Standard No. 12. Do you believe that Qwest had established an effective system of internal control over finan- cial reporting related to the presentation and disclosure of its nonrecurring revenue? Why or why not? Solution Yes, I believe this system will be effective as if an auditor understands the company control mechanism, he will be in a better position to analyse the authenticity of the Financial Statements. He will be able to analyse if there any misrepresentation in the statements or frauds with reagards to presentation and disclosure of its nonrecurring revenue. Because normally a company does not report it\'s nonrecurring revenues as it is not a regular income and club it with other incomes. So if an auditior is ware of company\'s control mechanism if will be i a better posiiton to judge the correctiveness of the financial statements..
