Auditor Independence and Non-Audit Services
You are the engagement partner for the audit of Mwangi & Co. Ltd, a private manufacturing company with annual revenue of KES 500 million. The company has been your audit client for five years. In the current year, the company has asked your firm to provide additional services: (1) design and implementation of a new inventory management system, and (2) tax advisory services related to a proposed restructuring. The total fees for these non-audit services would be KES 15 million, compared to audit fees of KES 8 million. The company's audit committee is not independent, as it consists solely of the managing director and the finance director. The company is not listed but has a bank loan that requires audited financial statements. The audit partner is concerned about the potential impact on independence and audit quality.
1. Evaluate the threats to independence arising from the proposed non-audit services and recommend whether the firm should accept the engagements. Justify your recommendation with reference to ethical principles and professional standards.

Threats to independence:
- Self-review threat: Designing and implementing an inventory management system could lead to the audit team reviewing their own work, as the system affects inventory valuation and controls.
- Self-interest threat: The non-audit fees (KES 15m) exceed audit fees (KES 8m), creating financial dependence on the client. This is particularly significant given the total fees from one client should not exceed 15% of the firm's total fees (for non-listed clients, a higher threshold may apply but still requires safeguards).
- Advocacy threat: Tax advisory on restructuring may involve promoting the client's position, potentially compromising objectivity.
- Familiarity threat: Five-year tenure and close relationship with management may impair professional skepticism, especially with an audit committee lacking independence.
Recommendation: The firm should not accept the inventory system design and implementation, as it creates a significant self-review threat that cannot be effectively mitigated. For tax advisory, the firm could accept only if it is limited to tax compliance or planning advice that does not involve management decision-making, and if safeguards are in place (e.g., separate teams, independent review). However, given the fee dependence and lack of independent oversight, the firm should decline both engagements to avoid compromising audit quality. Alternatively, the firm could resign from the audit if it wishes to provide the non-audit services, but that may not be in the client's best interest. The ethical principles of objectivity and professional competence and due care must be upheld. The audit committee's lack of independence further exacerbates the threats, as there is no effective oversight to mitigate them.
2. Discuss the safeguards that could be implemented if the firm decides to proceed with the tax advisory engagement only. Explain how these safeguards address the specific threats identified.

Safeguards for tax advisory engagement:
- Separate engagement teams: Assign different personnel to the audit and tax advisory, ensuring no overlap in decision-making. This reduces self-review and familiarity threats.
- Independent quality review: Have an independent partner review the tax advice and its impact on the audit. This addresses self-review and advocacy threats.
- Fee cap and disclosure: Limit non-audit fees to a proportion of total fees (e.g., not exceeding audit fees) and disclose to those charged with governance. This mitigates self-interest threat.
- Client acknowledgment of responsibility: Obtain written acknowledgment that management takes responsibility for tax decisions. This reduces advocacy threat.
- Audit committee oversight: Although the current committee is not independent, the firm could recommend strengthening it or obtain written confirmation from the board that they will oversee the engagement. This addresses familiarity and self-interest threats.
- Rotation of engagement partner: Consider rotating the audit partner after a set period to reduce familiarity threat.
These safeguards, if properly implemented, could reduce threats to an acceptable level. However, the lack of an independent audit committee remains a significant weakness, and the firm should document its rationale for accepting the engagement despite this.
