An audit report can be modified or unmodified. If modified, it can include a qualified *opinion*. A qualified opinion can be issued under 2 circumstances.
1. There is a misstatement that is material but not pervasive. 2. The auditor is unable to obtain sufficient appropriate evidence about an area or balance which is material but not pervasive.
In both the cases, the ‘Basis for opinion’ section will be modified to ‘Basis for qualified opinion’ to explain the reason for modification.
