The U.S.Sarbanes-Oxley Act:

A) has no impact on the supply management process.
B) affects internal accounting procedures of privately-held companies.
C) requires the Chief Purchasing Officer to sign off on every contract.
D) requires listing off-balance sheet items such as long-term purchase agreements.
E) requires supply management to report directly to the Chief Financial Officer.

The U.S. Sarbanes-Oxley Act requires companies to list off-balance sheet items such as long-term purchase agreements, which can impact supply management. However, it does not require the Chief Purchasing Officer to sign off on every contract or for supply management to report directly to the Chief Financial Officer. And while it primarily affects publicly-traded companies, some privately-held companies may also be impacted if they have certain levels of revenue or funding.
