Financial judgements and internal control matters
The Committee considered the following significant judgements, estimates
and internal control matters in preparing the 2021 Annual Report & Accounts,
coming to the following conclusions:
The Committee spent considerable time
during the year reviewing the significant
financial reporting judgements and key
accounting estimates associated with
the Company’s full and half-year results.
In this work the impact of climate change
and the energy transition was considered
recognising in particular the uncertainty
around the scale and timing of such impacts.
The Committee reviewed, in particular,
judgements and key accounting estimates
for the Merger, the impairment and
decommissioning provision assessments,
the appropriateness of the financial
modelling work that supported the going
concern recommendations, and the clarity
and completeness of disclosures in the
financial statements. More detail about
the work of the Committee in relation to
financial reporting judgements can be
found in the panel opposite.
During the year, the Committee received
reports on the outcome of the Internal Audits
conducted over the period. The audits
reviewed included treasury controls, cyber
security and UK financial controls in the
legacy Premier business, and the project
to implement a Company-wide Enterprise
Management System (EMS). In reviewing
these reports the Committee took note of
any significant findings and the closeout of
the actions agreed as a result of these
audits. The Committee also reviewed and
endorsed the Internal Audit plan for 2022.
Through the year the Committee also
received presentations on risk management
matters in support of its duty to monitor
and review the effectiveness of the
Company’s risk management and internal
control systems. Presentations included
the control environment in place on the
completion of the Merger; the risk
management framework being implemented
across the business; mapping of the
sources of assurance to assure effective
control across key risk areas; ethics and
compliance matters; and a proposal to
develop an Audit and Assurance policy
document. There was also a ‘deep dive’
presentation on cyber security as the first of
a series of management led presentations
to support understanding and alignment
on specific risk matters. The Committee
also reviewed the processes in place for
understanding the principal and emerging
risks facing the business, in support of
the Board’s review during the year.
Going concern
The Directors are required to consider the
appropriateness of adopting the going concern
basis of accounting. The Committee reviewed
management’s projections of the Group’s liquidity
position. Key assumptions in the projections
included those related to oil and gas prices during
the period. The Committee concluded that it is
satisfied that the judgements applied in making
the assumptions and estimates that underpin the
forecasts and projections have been exercised in an
appropriate manner. The going concern statement
included on page 43 is fair and balanced.
Purchase price accounting
In assessing the purchase price accounting for the
Merger, the Committee reviewed and challenged:
¼ management’s key assumptions for valuing
the acquired assets. This included approval of
management’s long-term planning assumptions
for crude oil prices of $65/bbl in real terms and
UK NBP gas prices of 60p/therm in real terms,
adjusted for the Group’s hedging programme;
¼ valuations of intangible exploration and
evaluation (E&E) assets taking into account the
various valuations available which comprise
financial carrying values, expected monetary
valuations from discounted cash flows and
potential sale proceeds from disposal initiatives;
¼ management’s key assumptions for
decommissioning provisions; and
¼ recoverability of tax credits associated with the
items above.
Impairment of tangible and intangible
properties
In assessing indicators of impairment or reversals
of previous impairments, the Committee:
¼ reviewed and challenged management’s key
assumptions for oil and gas properties, including
the long-term planning assumptions and future
oil and gas prices; and
¼ taking account of available market data,
approved management’s long-term planning
assumptions for crude oil prices of $75/bbl in
2022, $70/bbl in 2023, and $65/bbl (in real
terms) thereafter and for UK NBP gas prices of
150p/therm in 2022, 100p/therm in 2023 and
60p/therm (in real terms) thereafter, adjusted
for the Group’s hedging programme.
The Committee was satisfied that the most significant
assumptions on which the amount of the impairment
charge is based are future commodity prices, the
discount rate applied to the forecast future cash flows
and the decommissioning provisions. The Committee
considered the disclosure of the sensitivity of the
impairment charge to changes in the commodity
prices, as set out in note 12 to the financial
statements on page 139, to be appropriate.
The Committee noted that estimates of the Group’s
oil and gas proven and probable reserves prepared
by independent reservoir engineers were within one
per cent of management’s estimates.
The Committee assessed the carrying values of E&E
assets and whether any indicators of impairment
exist in relation to these assets. The Committee
reviewed the oil and gas resources estimates and
maturation reports from management and satisfied
itself that the resource movements in the year and
balances at year-end were appropriately prepared
and supported and that the corresponding E&E asset
carrying balances and income statement charges
were aligned with the resources reports. Details of
the Group’s intangible E&E assets are provided in
note 11 to the financial statements on page 138.
Oil and gas reserves and resources
The Committee considered reports from
management on the process applied to determine
the oil and gas reserves and resources estimates,
addressing in particular the extent to which the
methodology and techniques applied by the
Company were generally accepted industry practice,
whether the methodology and techniques applied
were consistent with those applied in prior years,
and the experience and expertise of the managers
who prepared and reviewed the estimates. The
Committee noted that estimates of the Group’s oil
and gas proven and probable reserves prepared
by independent reservoir engineers were within
one per cent of management’s estimates.
The Committee discussed with management the
main reasons for the difference between the two
estimates and was satisfied that it was appropriate
to apply management’s estimates for the purpose
of preparing the financial statements.
Provisions for decommissioning
The Committee discussed with management the
estimation process and the basis for the principal
assumptions underlying the cost estimates for
future decommissioning activity, noting in particular
the reasons for any major changes in estimates as
compared with the previous year. The Committee
was satisfied that the approach applied was fair and
reasonable. The Committee was also satisfied that the
combination of discount and contracted rig rates used
to calculate the provision was appropriate. Further
information on decommissioning provisions is provided
in note 20 to the financial statements on page 145.
Taxation
The Committee discussed with management
their projections of probable UK taxable profits
and noted that these projections include existing
producing assets and certain currently unsanctioned
UK development projects. The projections use
underlying assumptions which are consistent with
those used in the asset impairment review and
support the recognition of a net deferred tax asset.
Further details of the deferred tax asset and the
assumptions used to estimate the amount of tax
recoverable in respect of tax losses and allowances
are provided in note 8 to the financial statements
on page 135.
