When might an auditor continue for two years after a partner leaves for a client?

The situation wherein an auditor might continue for two years after a partner leaves for a client primarily revolves around the importance of transparency and communication in the auditing process. In this context, clear disclosures made about the circumstances of the partner's departure and the continuation of the auditing relationship are essential for maintaining trust and ensuring that stakeholders are fully informed about any potential conflicts of interest or threats to independence.

Making clear disclosures allows the audit firm to mitigate potential concerns regarding objectivity or bias that could arise from the partner's departure. By openly communicating these details, the firm can demonstrate its commitment to ethical practices and compliance with relevant auditing standards and regulations. This transparency helps stakeholders understand the continued choice of the firm and can alleviate any worries about the integrity of the audit process.

In contrast, the other options present considerations that don't hold the same weight in terms of allowing an auditor to continue in this scenario. Significant threats generally require immediate action rather than an extension of the engagement period. The size of the client can influence the audit process but does not inherently allow for the continuation of an auditing relationship without addressing potential risks. Management agreement alone isn't sufficient to justify extending the relationship without appropriate disclosures to ensure all parties are aware of the situation.
