Underlying subject matter

The underlying subject matter is the phenomenon or activity measured or evaluated against suitable criteria in an assurance engagement. The measurement or evaluation produces subject matter information, on which the practitioner obtains evidence and expresses a conclusion. It may be financial position and performance, or an organisation’s greenhouse gas emissions.

Worked example

For emissions assurance, the entity’s emissions are the underlying subject matter; its calculated emissions statement is the subject matter information.

Common mistake

Do not confuse the underlying activity with the resulting report about it.
