You are a senior manager in Bunk & Co, a global audit firm with offices in more than 30 countries. You are responsible for monitoring audit quality and ethical situations which arise in relation to audit clients. Wire Co is an audit client whose operations involve haulage and distribution. The audit report for the financial statements of Wire Co for the year ended 31 December 2014 was issued last week. You are conducting a review of the quality of that audit, and of any ethical issues which arose in relation to it. Relevant information obtained from a discussion with Lester Freeman, the audit engagement partner, is given below.

(a) Wire Co’s audit committee refused to agree to an increase in audit fees despite the company’s operations expanding into new locations. In response to this, the materiality level was increased during the audit, and some review procedures were not carried out. To reduce sample sizes used in tests of detail, the samples were selected based on judgement rather than statistical methods. In addition, only parts of the population being tested were sampled, for example, certain locations were not included in the sample of non-current assets selected for physical verification.
