What is the impact on independence when a CPA is asked to co-sign checks for a client while the president is on vacation?

The correct choice highlights a fundamental principle in CPA ethics regarding independence. When a CPA is asked to co-sign checks for a client, this action constitutes performing a management function. In essence, it places the CPA in a role typically reserved for the client's management, which can compromise the object's relationship needed for an audit or any other professional conduct requiring independence.

Independence is essential for the CPA profession as it ensures that the accounting professional can make unbiased decisions and provide an impartial assessment of the client's financial statements. By engaging in activities such as check signing, a CPA may inadvertently take on responsibilities that could influence their judgment and objectivity, undermining the trust required in the public accounting profession.

The implications of this role assignment are significant. Even if the check-signing task appears temporary, it still engages the CPA in the client's operations in a way that conflicts with maintaining their independence. The concern over neutrality and objectivity leads to the conclusion that such actions impair independence regardless of the duration of the role or the size of the checks involved. Thus, it is vital for CPAs to avoid any management functions to preserve their independence fully.
