AUDIT COMMITTEE REPORT continued
that there was sufficient headroom to
agree with the Board’s confirmation that
the Group has a reasonable expectation
to continue in operation and meet
its liabilities as they fall due over the
viability period. Alongside the liquidity
and debt positions of the business, the
Committee determined that the three-
year measurement period continued
to be appropriate and that the viability
statement (as set out on page 49)
should be recommended to the Board
for approval.
(E) Future IFRS and UK GAAP
developments
During the year, there were no
changes to the Group’s accounting
policies and there were no new
accounting standards.
Fair, balanced andreasonable
The process to ensure the Group’s
financial statements, taken as a whole,
are fair, balanced and reasonable is:
• comprehensive guidance issued to
all contributors
• verification process dealing with
the factual content of the report
• review of the disclosure
judgements made by the
contributors from various functions
• comprehensive reviews undertaken
to ensure consistency and overall
balance
• review undertaken by
the Committee prior to
recommendation to the Board.
Audit, risk and internal control
The Board assumes ultimate
responsibility for the effective
management of risk across the
Group. However, the Committee
helps the Board in its monitoring
of the Company’s internal financial
control and internal controls and risk
management systems, and monitoring
and reviewing the work of the internal
audit and risk function.
Internal audit
The internal audit and risk function
has an integral role in the Company’s
governance structure, providing
independent assurance and advice to
help the Group achieve its strategic
priorities. The Committee agreed the
2021 audit plan to be undertaken by
the internal audit team and assessed
the adequacy of the budget and
resources. The audit plan is based
on risk, strategic priorities and
consideration of the strength of the
control environment. Progress against
the plan is monitored. The Committee
reviews the results of the internal audit
reports at each meeting. Management
is responsible for ensuring that issues
raised by internal audit are addressed
within the agreed timetable and their
timely completion is reviewed by the
Committee. Where internal or external
circumstances give rise to an increased
level of risk, the audit plan is modified
accordingly during the year.
The head of internal audit and risk
continues to report directly into
the Committee chair with a second
reporting line to the CFO (previously to
the CEO) for administrative purposes.
During the year the Committee received
the results of the head of internal audit
and risk’s annual performance review.
It also reviewed statistics on key staff
numbers, qualifications and experience
which the Committee considered to
besatisfactory.
The effectiveness of internal audit
is assessed by the Committee by:
reviewing the results of an annual
questionnaire completed by individuals
who have exposure to and contact with
the internal audit function; evaluating
internal audit reports; and meetings
with the chair of the Committee without
management present. The Committee
is satisfied the function is competent to
deliver the 2022 internal audit plan.
Internal control and risk
Details of the Group’s internal controls
and risk management framework are
more fully set out on pages 44 and 45
in the Strategic Report and page 73 in
the Governance Report. The Group’s
principal risks are set out on pages
46 to 48.
The Committee has evaluated the
effectiveness of the systems operated
within the Group pursuant to the FRC’s
guidance on internal control. The
evaluation covered all material controls.
These included financial, operational and
compliance controls. They encompassed
a review of: the management
confirmation reports submitted by all
senior management; controls reports;
reports on fraud perpetrated against
the Group; the Group’s approach
to anti-bribery and corruption and
whistleblowing; and reports from both
the internal and external auditors.
The review did not identify any
significant weaknesses in the system of
internal control and risk management.
Management has identified a range
of potential solutions to expedite
the required rectification works. The
Committee has carefully assessed
the maximum potential risk and
likely scenarios and agree with
management’s best estimate cost of
the single most likely solution as at
31 December 2021 is £6.2m. A provision
for this probable economic outflow
has been recognised and disclosed
in note 20 on pages 166 and 167.
(B) Pension
The Group’s defined benefit pension
scheme requires significant judgements
to be made in relation to the assumptions
for inflation, future pension increases,
investment returns and member
longevity that underpin the valuation.
Each year, in selecting the appropriate
assumptions, the Company takes written
advice from an independent qualified
actuary. The Committee has critically
reviewed these assumptions and
considers them to be reasonable. These
assumptions and sensitivities are set out
in note 21 on pages 167 to 171 of the
financial statements.
(C) The carrying value of goodwill
and intangible assets
As set out in note 12 on pages 151
and 152 of the financial statements,
the goodwill and acquired intangible
balances within the Group relate to
companies acquired by the Group. In
particular, the Committee reviewed the
carrying value of the goodwill within
the Natural Resources division and
critically reviewed the key assumptions
in relation to forecast operating margin,
the discount rates and long term
growth rates. The Committee agreed
with management’s assessment that
no impairment was required.
(D) Going concern and
viability statement
The Committee considered the
requirements of the 2018 Code as
it applies to the Group’s viability
statement including the three-year
period of assessment which aligns
with the Group’s planning horizon
and the processes supporting the
viability statement. The Committee
considered the various scenarios that
were presented as part of the viability
assessment, which included a reverse
stress test, mitigations and severe but
plausible scenario analysis relating to the
Group’s principle risks. The Committee
assessed the appropriateness of the
downside scenarios and determined
