Delegated duties

In executing its delegated duties and making its assessments (as reflected in its terms of reference), the committee obtained feedback from external and internal audit and, based on the processes and assurances obtained, believes the accounting practices are effective. Accordingly, the committee fulfilled all its obligations set out below.

Integrated reporting
Internal audit
Risk management

The committee is an integral component of the risk management process and specifically reviewed:

External audit
Financial director

The committee has satisfied itself of the appropriateness of the expertise and experience of Ms Ramano, the financial director, and confirms this to shareholders.

Financial function
Oversight of risk management

The committee engages with the risk and compliance committee to ensure adequate understanding of risk management processes.

Internal financial controls
Key areas from the year-end audit report

As noted in the directors' report, preparing the financial statements requires management and the board to exercise judgement in compiling financial information. To the extent that significant judgement was applied, appropriate disclosure is reflected in the respective notes to the financial statements.

The auditors also report on matters they deem significant. These are discussed in their report on page 136 of the financial statements.

In finalising the consolidated annual financial statements for the year ended March 2018, the audit committee considered the following balances to have been prepared with a significant amount of judgement:

Potential impairment of significant assets

PPC group performs impairment calculations twice each year, at interim and at year-end stage. All subsidiaries of PPC Ltd are assessed for indications or conditions that may suggest an impairment. In accordance with IAS 36.10(a) and (b), the following are assessed irrespective of whether there is any indication of impairment:

Where such an indication exists, PPC estimates the recoverable amount of the asset and compares this to the current carrying amount of the entity and the goodwill balance (where applicable) (IAS 36.09).

PPC measures the recoverable amount as value in use, as it expects to recover the value of the asset through use, unless an asset has been identified as held for sale or there is a suitable market where fair values are readily available. The selection of an appropriate method is prescribed by IFRS requirements.

The group has expanded into the DRC and Rwanda, with the DRC plant commissioned in the current financial year. The plant in Rwanda was commissioned in calendar 2016. PPC has been operating in Zimbabwe since acquiring the business in 2001, with a further investment in a cement mill in Harare which was commissioned in the previous financial year.

Given the economic and political environments and life-of-mine estimates, impairment assessments were undertaken by management on all subsidiaries.

The audit committee reviewed and debated assumptions used by management in preparing the impairment assessments, under the discounted cash flow model, including the weighted average cost of capital applicable to each subsidiary. It concluded that there was no impairment required on CIMERWA, PPC Zimbabwe, PPC Cement RSA and the rest of the materials businesses. However, on reviewing the PPC Barnet DRC subsidiary's discounted cash flows, the committee concluded that an impairment of this operation was appropriate and concurred with management on an impairment of US$14 million (R165 million). It was also noted that management should continue to monitor the impairment indicators and, if still applicable by the time the company finalises its 2019 half-year results, further impairment reviews should be performed.

The committee also noted constraints in remitting funds from Zimbabwe as a result of in-country liquidity issues and the potential impact on the going concern assumption. In addition, the committee noted the disclosure of Zimbabwe's cash and cash equivalents at year-end.

Capitalisation of plant expansion costs and capitalisation date for the DRC plant

The 1.2mtpa plant in the DRC was commissioned in the current financial year. In determining the most appropriate commissioning date, management considered various factors, to determine when the plant would be in the condition necessary for it to operate in the manner intended by management.

The committee reviewed management's assessment of when the plant would be deemed to be operating in this manner, taking account of significant factors listed in the property, plant and equipment note on determining commissioning dates and timing of performance acceptance certificates.

In addition, the committee debated the process followed by management to determine appropriate costs to be capitalised to plant and equipment. It concurred with management's assessment on the commissioning date of 1 November 2017.

The committee reviewed management's assessment of the DRC plant's capital work in progress account and the exercise undertaken to transfer expenditure to the fixed assets register and expensing of US$6 million of expenditure previously capitalised to plant under capital work in progress.

Regulatory compliance

The committee has fulfilled all its statutory duties as per the requirements of section 94(7) of the Companies Act. The committee also complies with paragraph 3.84(g) of the JSE Listings Requirements.
