Some situations may result in modified audit opinions, such as departures from GAAP and scope limitations.

With regard to comparative financial statements, please consider the following questions:

1. Must the audit report address all statements presented when the client presents comparative statements?
2. Can auditors express different opinions on the statements, and also different opinions on different financial statements issued for a given year?
3. Should continuing auditors update their opinion on prior years statements if those statements are presented for comparative purposes?
