In what circumstance may a member withdraw from an engagement?

A member may withdraw from an engagement primarily when they lack the necessary skills to perform the services required. The integrity and quality of services provided by a CPA are paramount, and acknowledging one's limitations is a key ethical obligation. If a CPA determines that they do not possess the requisite expertise or knowledge to complete an engagement competently, it is ethical and responsible to withdraw, rather than potentially compromise the quality of the work or the client's financial reporting.

In this context, maintaining professional competence aligns with the fundamental principles of the CPA profession, which emphasize the importance of serving clients with the necessary skill and expertise. This adherence to professional standards not only protects the CPA's reputation but also safeguards the interests of clients and stakeholders.

The other options may not justify withdrawal in the same manner. For instance, client displeasure might warrant discussions or attempts at resolution rather than withdrawal. Conflicts of interest require careful management and disclosure, but may not necessitate exiting the engagement if addressed appropriately. Overseeing costs related to audits is a matter of financial management and does not inherently concern the CPA's competence or ethical obligations in the same way that skills do.
