Complexity Understandability Scalability Proportionality (CUSP)

What the Project Aims to Achieve


The objective of this workstream was to develop drafting principles and guidelines to address complexity, understandability, scalability and proportionality (CUSP) in developing International Standards on Auditing (ISAs).

In its April 2022 meeting, the IAASB unanimously agreed to adopt the CUSP Drafting Principles and Guidelines as part of its internal procedures for drafting Exposure Drafts and Standards.  The CUSP Drafting Principles and Guidelines are to be applied prospectively. The IAASB intends to maintain the Drafting Principles and Guidelines on an ongoing basis.
