The Sarbanes-Oxley Act of 2002, modified the requirements in the Exchange Act rules such that, effective starting in 2002, principal executive officers of publicly traded companies must include certain certifications in the annual report on Form 10K and also in the quarterly reports on Form 10-Q.

Name each certification report in the annual report on Form 10K and the section of the Sarbanes Oxley act that requires it.
Explain why you think that requiring executive officers to make affirmative claims such as these reports and certifications is an effective (or ineffective) deterrent to financial reporting irregularities.
