Final answer:
The correct statement about audit documentation review is that, for larger audits, it is common to have the financial statements and audit files reviewed by a member of the audit firm who did not participate in the audit.
Step-by-step explanation:
The accurate statement regarding audit documentation review is: "C) For larger audits, it is common to have the financial statements and the entire set of audit files reviewed by someone who has not participated in the audit, but is a member of the audit firm doing the audit." This process is known as a concurring partner review or engagement quality review and it aims to ensure the quality and integrity of the audit. The reviewer provides an independent assessment of the significant judgments the audit team made and the conclusions they reached. It is part of quality control procedures for audits.
Regarding the other options, the audit partner does focus on the work of less experienced auditors, but not necessarily 'in more detail' than that of the audit supervisor as indicated in A). The audit senior (B) typically reviews documentation but might not review all audit documentation unless it's part of their specific assignment or role. Finally, statement D) is incorrect since checklists are widely used in audit processes to ensure that all necessary disclosures have been made and steps have been followed properly.
