The composition of the Audit Committee meets with the requirements of the UK Corporate Governance Code (April 2016) and is reviewed regularly. All committee members during the year were independent non-executive directors in accordance with the Code. The members have been selected to provide the wide range of financial and commercial expertise necessary to fulfil the committee's duties. Tony Osbaldiston and Chris Holt are chartered accountants.

By invitation, there were a number of other regular attendees including internal and external auditors. Alan Dunsmore, Adam Semple and Mark Sanderson also attended each meeting by invitation.

Meetings are held at least three times per annum and additional meetings may be requested by the external auditor. The committee met on three occasions during the year.

Role and key responsibilities

The primary function of the committee is to assist the board in fulfilling its oversight responsibilities. This includes reviewing the financial reports and other financial information before publication. The committee assists the board in achieving its obligations under the Code in areas of risk management and internal control, focusing particularly on areas of compliance with legal requirements, accounting standards and the Listing Rules (Listing Authority Rules for companies listed on the London Stock Exchange), and ensuring that an effective system of internal financial and non-financial controls is maintained.

The committee also reviews the accounting and financial reporting processes, along with reviewing the roles of and effectiveness of the external auditor. The ultimate responsibility for reviewing and approving the annual report remains with the board.

The responsibility of the committee principally falls into the following areas:

  • To monitor the integrity of the financial statements and formal announcements and to review significant financial reporting judgements.
  • To review the Group's internal financial and non-financial controls and risk management.
  • To make recommendations to the board in relation to the appointment and removal of the external auditor and to approve its remuneration and its terms of engagement.
  • To review the nature of non-audit services supplied and non-audit fees relative to the audit fee.
  • To provide independent oversight over the external audit process through agreeing the suitability of the scope and approach of the external auditor's work, assessing its objectivity in undertaking its work and monitoring its independence, taking into account relevant UK professional regulatory requirements and the auditor's period in office and compensation.
  • To oversee the effectiveness of the internal audit process.
  • To oversee the effectiveness of the external audit process, particularly with regard to the quality and cost-effectiveness of the auditor's work.
  • To report to the board how it has discharged its responsibilities.

Activities of the committee

The committee addressed the following key agenda items in relation to the 2018 financial year:

  • Reviewed the interim results for the period ended 30 September 2017 and the year-end results for the period ended 31 March 2018.
  • Reviewed the significant management judgements reflected in the Group's results including significant contract judgements and the carrying value of the investment in the Indian joint venture.
  • Discussed the report received from the external auditor regarding the audit of the results for the year ended 31 March 2018. This report included the key accounting considerations and judgements reflected in the Group's year-end results, comments on findings on internal control and a statement on independence and objectivity.
  • Reviewed and agreed significant accounting risks and principal business risks for the year ended 31 March 2018.
  • Reviewed the Group's risk register.
  • Reviewed and agreed the external auditor's audit planning report in advance of the audit for the year ended 31 March 2018.
  • Reviewed the measures taken by management to monitor and review the effectiveness of the Group's internal control and risk management processes, to enable the board to make its annual review of effectiveness.
  • Reviewed the long-term viability statement and the process undertaken by executive management to enable the board to make the viability statement.
  • Considered the effectiveness of the external auditor, KPMG LLP ('KPMG'), their independence and reappointment for the year ending 31 March 2019.
  • Reviewed PwC LLP's ('PwC') internal audit reports covering various aspects of the Group's operations, controls and processes and approved the internal audit plan.

Fair, balanced and understandable

The committee was provided with, and commented on, a draft copy of the annual report. At the request of the board, the committee also considered whether the annual report was fair, balanced and understandable and whether it provided the necessary information for shareholders to assess the Group's performance, business model and strategy. To enable the board to make this declaration, the committee received a paper from management detailing the approach taken in preparing the annual report. The committee is satisfied that, taken as a whole, the annual report and accounts is fair, balanced and understandable.

In carrying out the above processes, key considerations included ensuring that there was consistency between the financial statements and the narrative provided in the front half of the annual report (and that the use of alternative performance measures was appropriate and clearly articulated), that there is a clear and well-communicated link between all areas of disclosure and that the strategic report focused on the balance between the reporting of weaknesses, difficulties and challenges, as well as successes, in an open and honest manner. In addition, the external auditor reviewed the consistency between the narrative reporting in the annual report and the financial statements.

Risk management and internal control

The board as a whole, including the audit committee members, considers the nature and extent of the Group's risk management and internal control framework and the risk profile that is acceptable in order to achieve the Group's strategic objectives. As a result, it is considered that the board has fulfilled its obligations under the Code.

Details of the Group risk management and internal control processes are set out in the risk management section of the strategic report.


The Group operates a comprehensive whistleblowing policy. Accordingly, staff may, in confidence, raise concerns about possible improprieties in matters of financial reporting or other matters. The committee reviews adherence with this policy on an ongoing basis.

Viability statement

The committee has undertaken a detailed assessment of the viability statement and recommended to the board that the directors could have a reasonable expectation that the Company will be able to continue in operation and meet its liabilities as they fall due over the three-year period of their assessment. The viability statement can be found in the financial review section of the strategic report.

Financial reporting and significant financial issues

The committee assesses whether suitable accounting policies have been adopted and whether management has made appropriate estimates and judgements. The committee reviews accounting papers prepared by management which provide details on the main financial reporting judgements.

In the 2017 annual report, the carrying value of goodwill and other non-current assets was classified as a significant accounting risk which covered the impairment risks associated with both goodwill and the investment in the Indian joint venture. Given the strong profitability of the underlying business to which goodwill relates, the goodwill component of this item is no longer classified as a risk in the 2018 annual report.

The two significant issues considered during the year are detailed below:

Contract valuation, revenue and profit recognition:

The committee reviewed the report of the Group finance director that set out the main contract judgements associated with the Group's significant contracts. The significant areas of judgement include the timing of revenue and profit recognition, the estimation of the recoverability of contract variations and claims, the estimation of future costs to complete and the estimation of claims received by the Group. The external auditor performed detailed audit procedures on revenue and profit recognition and reported their findings to the committee.

Review of carrying value of investment in the Indian joint venture:

The committee considered the carrying value of investments in the Indian joint venture and the assumptions underlying the impairment review. The judgements in relation to impairment largely relate to the calculation of the value in use of the assets being tested for impairment, primarily the achievability of long-term business plans and macroeconomic assumptions underlying the valuation process.

The committee was satisfied that each of the matters set out above had been fully and adequately addressed by management, appropriately tested and reviewed by the external auditor and that the disclosures made in the annual report were appropriate.

In addition, the committee has considered a number of other judgements which have been made by management, none of which had a material impact on the Group's 2018 results. These include the valuation of pension scheme liabilities and the disclosure of certain contingent liabilities.

Internal audit

The Group's internal audit function is currently outsourced to PwC. The committee is responsible for reviewing the role and effectiveness of the internal audit function by monitoring the results of its work and the responses of management to its recommendations. The scope of PwC's work focused on key financial controls and non-financial reviews covering areas of perceived higher business risk. Results and management actions arising from reviews undertaken by PwC in the current year were also discussed in detail at each of the committee's meetings.

External auditor independence and effectiveness

The year ended 31 March 2018 marks the third year during which KPMG has acted as the Group's external auditor. The committee considers the reappointment of the external auditor, including the rotation of the senior statutory auditor, annually. This also includes an assessment of the external auditor's independence and an assessment of the performance in the previous year, taking into account detailed feedback from directors and senior management across the Group.

The committee also assesses the effectiveness, independence and objectivity of the external auditor by, amongst other things:

  • considering all key external auditor plans and reports;
  • having regular engagement with the external auditor during committee meetings and ad hoc meetings (when required), including meetings without any member of management being present;
  • the chairman of the committee having discussions with Adrian Stone, the senior statutory auditor, ahead of each committee meeting; and
  • considering the external audit scope, the materiality threshold and the level of audit and non-audit fees.

Following this assessment of the external audit process, the committee agreed that the audit process, independence and quality of the external audit were satisfactory. The committee will continue to assess the performance of the external auditor to ensure that they are satisfied with the quality of services provided.

Reappointment of external auditor

The statutory audit services order ('the Order') requires rotation of audit firms every 10 years unless there is a tender, in which case the audit firm can remain as auditor for up to 20 years.

As previously reported, KPMG were selected as the Group's auditor for the year ended 31 March 2016, following a competitive tender process, and were appointed at the AGM on 2 September 2015. The external auditor is required to rotate the senior statutory auditor every five years. The senior statutory auditor responsible for the Group audit for 2018 is Adrian Stone, whose appointment in this role commenced with the audit for the financial year ended 31 March 2016. Following Adrian's decision to retire from KPMG in late 2018, the new statutory auditor responsible for the Group audit for 2019 will be David Morritt, subject to the reappointment of KPMG at the AGM.

The committee has recommended to the board that a resolution proposing the appointment of KPMG as external auditor be put to the shareholders at the forthcoming AGM.

Non-audit services

The Group's policy on the engagement of the external auditor for non-audit related services is designed to ensure that the provision of such services does not impair the external auditor's independence or objectivity. Under no circumstances will any assignment be given to the external auditor when the result would be that:

  • as part of the statutory audit, it is required to report directly on its own non-audit work;
  • it makes management decisions on behalf of the Group; or
  • it acts as advocate for the Group.

This policy is compliant with the Code and with the FRC's revised Guidance on Audit Committees. It includes restrictions on the scope of permissible non-audit work and a cap on fees for permissible non-audit work (which may not exceed 70 per cent of the average audit fees paid in the last three consecutive years). The policy requires a competitive tender for all work with a fee over £30,000.

For work that is permitted under the policy, authority is delegated to the Group finance director to approve up to a limit of £50,000 for each assignment and there is a cumulative annual total of less than 50 per cent of that year's audit fee. Prior approval is required by the committee for any non-audit assignments over £50,000 or where the 50 per cent audit fee threshold is exceeded. No non-audit services provided by KPMG during the year ended 31 March 2018 required the approval of the committee.

Details of the auditor's fees, including non-audit fees (which comply with the Group's policy on the provision of non-audit services), are shown in note 4 to the consolidated financial statements. The total non-audit fees for 2018 represent 16 per cent of the total KPMG audit fee. Those non-audit services undertaken by the auditor were purchased from the auditor because of its existing knowledge of the Group's business which meant it could undertake them more effectively.
