Comments:

This transaction was recorded in the wrong period and not included in the accounts payable as of Year 2019. We expanded our test by completing the following: test of details of transactions recorded from 01/01/2020 to 10/01/2020. This error seems to be isolated as no additional errors were detected. The error is posted to our summary of audit differences.

Required:

1.Why does an auditor test accounts payable cut-off? Discuss whether the test has any implications for the income statement?

2.Explain the error found by the auditor in the second transaction on the working paper.

Why has the auditor done additional testing (see the comments section)?
