Dear Committee Members,
Annual Audit Plan – Year ending 31 March 2025
We are pleased to present our Annual Audit Plan for West Dunbartonshire Council for the year ending 31 March 2025. This report summarises our audit approach, including the significant
audit risks and areas of key judgement we have identified, and provides details of our audit team. In addition, as it is a fundamental requirement that an auditor is, and is seen to be,
independent of an audited entity, the section of the report titled ‘Confirmation of our independence’ summarises our considerations and conclusions on our independence as auditors.
Two-way communication with you is key to a successful audit and is important in:
• Reaching a mutual understanding of the scope of the audit and our respective responsibilities;
• Sharing information to assist each of us to fulfil our respective responsibilities;
• Providing you with constructive observations arising during the audit process; and
• Ensuring that we, as external auditors, gain an understanding of your attitude and views in respect of the internal and external operational, financial, compliance, and other risks
facing West Dunbartonshire Council which may affect the audit, including the likelihood of those risks materialising and how they are monitored and managed.
With that in mind, this report, which has been prepared following our initial planning discussions with management, facilitates a discussion with you on our audit approach. We welcome
any questions, concerns, or input you may have on our approach or role as auditor.

Engagement and responsibilities summary
We are appointed to perform the external audit of West Dunbartonshire Council for the year to 31 March 2025. The scope of our engagement is set out in the Code of Audit Practice,
issued by the Auditor General and the Accounts Commission available from the Audit Scotland website: Code of audit practice | Audit Scotland (audit-scotland.gov.uk). Our
responsibilities are principally derived from the Local Government (Scotland) Act 1973 (the 1973 Act) and the Code of Audit Practice, as outlined below and overleaf.
Audit opinion
We are responsible for forming and expressing an opinion on whether the
financial statements are prepared, in all material respects, in accordance
with applicable law and UK adopted international accounting standards as
interpreted and adopted by the Code of Practice on Local Authority
Accounting un the United Kingdom 2024/25.
Our audit does not relieve management or Audit Committee, as Those
Charged With Governance, of their responsibilities.
Management is responsible for the assessment of the Council’s ability to
continue as a going concern. As auditors, we are required to obtain
sufficient, appropriate audit evidence regarding, and conclude on:
a) whether a material uncertainty related to going concern exists, and
b) the appropriateness of the Management’s use of the going concern
basis of accounting in the preparation of the financial statements.
Fraud
The responsibility for safeguarding assets and for the prevention and detection
of fraud, error, and non-compliance with law or regulations rests with both you
and management. This includes establishing and maintaining internal controls
over asset protection, compliance with relevant laws and regulations, and the
reliability of financial reporting.
As part of our audit procedures in relation to fraud, we are required to inquire of
you and key management personnel and internal audit, on their knowledge of
instances of fraud, and their views on the risks of fraud and on internal controls
that mitigate those risks. In accordance with International Standards on
Auditing (UK), we plan and perform our audit to obtain reasonable assurance
that the financial statements taken as a whole are free from material
misstatement, whether due to fraud or error. However, our audit should not be
relied upon to identify all such misstatements.

Engagement and responsibilities summary (continued)
Internal control
Management is responsible for such internal control as management
determines is necessary to enable the preparation of financial statements that
are free from material misstatement, whether due to fraud or error.
We are responsible for obtaining an understanding of internal control relevant
to the audit in order to design audit procedures that are appropriate in the
circumstances, but not for the purpose of expressing an opinion on the
effectiveness of Council‘s internal control.
Wider reporting
We report to the National Audit Office on the consistency of the Council’s
financial statements with its Whole of Government Accounts (WGA)
submission. The level of auditor assurance required depends on monetary
thresholds set by HM Treasury.
Wider scope and Best Value
We are also responsible for reviewing and reporting on the wider scope
arrangements that the Council has in place and its arrangements to secure
Best Value. We discuss our approach to wider scope and Best Value work
further in the ‘Wider scope and Best Value’ section of this report.

Audit scope, approach, and timeline (continued)
Audit scope
Our audit approach is designed to provide an audit that complies with all professional requirements.
Our audit of the financial statements will be conducted in accordance with International Standards on Auditing (UK), relevant ethical and professional standards, our own audit
methodology, and in accordance with the terms of our engagement. Our work is focused on those aspects of your business which we consider to have a higher risk of material
misstatement, such as those impacted by management judgement and estimation, application of new accounting standards, changes of accounting policy, changes to operations, or areas
found to contain material errors in the past.
Audit approach
Our audit approach is risk-based, and the nature, extent, and timing of our audit procedures are primarily driven by the areas of the financial statements we consider to be more susceptible
to material misstatement. Following our risk assessment where we assess the inherent risk factors (subjectivity, complexity, uncertainty, change and susceptibility to misstatement due to
management bias or fraud) to aid in our risk assessment, we develop our audit strategy and design audit procedures to respond to the risks we have identified.
If we conclude that appropriately designed controls are in place, we may plan to test and rely on those controls. If we decide controls are not appropriately designed, or we decide that it
would be more efficient to do so, we may take a wholly substantive approach to our audit testing where, in our professional judgement, substantive procedures alone will provide sufficient
appropriate audit evidence. Substantive procedures are audit procedures designed to detect material misstatements at the assertion level and comprise tests of detail (of classes of
transaction, account balances, and disclosures), and substantive analytical procedures. Irrespective of our assessed risks of material misstatement, which takes account of our evaluation
of the operating effectiveness of controls, we are required to design and perform substantive procedures for each material class of transaction, account balance, and disclosure.
Our audit has been planned and will be performed to provide reasonable assurance that the financial statements are free from material misstatement and give a true and fair view. The
concept of materiality and how we define a misstatement is explained in the ‘Materiality and misstatements’ section of this report.
The diagram on the next page outlines the procedures we perform at the different stages of our audit. We have also provided, later in this report, a table setting out the procedures we
perform for the significant financial statement areas.
Reliance on internal audit
Where possible, we use the work performed by internal audit when designing the nature, extent, and timing of our audit procedures. We will discuss with internal audit the progress of their
work and their findings prior to commencing our controls evaluation procedures.
We do not expect to use the work of the internal audit function for the purpose of our audit. Nonetheless, we will obtain the reports issued by internal audit relating to the financial period
under audit to determine whether any findings will have an impact on our risk assessment and planned audit procedures.

Group audit approach
The preliminary scope of our group audit is based on our analysis of the risks we have identified at group level. When scoping our audit, we have considered quantitative criteria (the
contribution of each of the group’s consolidated components to the group financial statements); qualitative criteria (the risks of material misstatement of the group financial statements
that consolidated components may present individually at component level); and we have assessed the risk of material misstatement across the group’s consolidated components in
aggregate.
The nature and extent of audit work we plan to perform on the consolidated components is set out below.

Audit scope, approach, and timeline (continued)
Audit of trusts registered as Scottish charities
The Charities Accounts (Scotland) Regulations 2006 outline the accounting and auditing requirements for charitable bodies. The 2006 Regulations require charities to prepare annual
accounts and an auditor to prepare a report to the charity trustees where any legislation requires an audit.
The Local Government (Scotland) Act 1973 specifies the audit requirements for any trust fund where some or all members of a Council are the sole trustees. Therefore, a full and separate
audit and independent auditor’s report is required for each registered charity where members of the Council are sole trustees.
Members of the Council and other local authorities are the trustees for four trusts registered as West Dunbartonshire Council Charitable Trusts, with total assets of £266,833. The
preparation and audit of financial statements of registered charities is regulated by the Charities and Trustee Investment (Scotland) Act 2005 and the Charities Accounts (Scotland)
Regulations 2006.
We have not identified any significant risks, other than the risk of management override of controls which we have also identified as a risk for the Council’s annual accounts, for the financial
statements of the West Dunbartonshire Council Charitable Trusts.

Materiality and misstatements
20
Definitions
Materiality is an expression of the relative significance or importance of a particular matter
in the context of the  financial statements as a whole.
Misstatements in the financial statements are considered to be material if they could,
individually or in aggregate, reasonably be expected to influence the economic decisions
of users based on the financial statements.
Materiality
We determine materiality for the financial statements as a whole (overall materiality) using
a benchmark that, in our professional judgement, is most appropriate to entity. We also
determine an amount less than materiality (performance materiality), which is applied
when we carry out our audit procedures and is designed to reduce to an appropriately low
level the probability that the aggregate of uncorrected and undetected misstatements
exceeds overall materiality. Further, we set a threshold above which all misstatements we
identify during our audit (adjusted and unadjusted) will be reported to Those Charged With
Governance.
Judgements on materiality are made in light of surrounding circumstances and are affected
by the size and nature of a misstatement, or a combination of both. Judgements about
materiality are based on a consideration of the common financial information needs of
users as a group and not on specific individual users.
An assessment of what is material is a matter of professional judgement and is affected by
our perception of the financial information needs of the users of the financial statements. In
making our assessment we assume that users:
• Have a reasonable knowledge of business, economic activities, and accounts;
• Have a willingness to study the information in the financial statements with reasonable
diligence;
• Understand that financial statements are prepared, presented, and audited to levels of
materiality;
• Recognise the uncertainties inherent in the measurement of amounts based on the
use of estimates, judgement, and consideration of future events; and
• Will make reasonable economic decisions based on the information in the financial
statements.
We consider overall materiality and performance materiality while planning and performing
our audit based on quantitative and qualitative factors.
When planning our audit, we make judgements about the size of misstatements we
consider to be material. This provide a basis for our risk assessment procedures, including
identifying and assessing the risks of material misstatement, and determining the nature,
timing and extent of our responses to those risks.
The overall materiality and performance materiality that we determine does not necessarily
mean that uncorrected misstatements that are below materiality, individually or in
aggregate, will be considered immaterial.
We revise materiality as our audit progresses should we become aware of information that
would have caused us to determine a different amount had we been aware of that
information at the planning stage.
For the consolidated financial statements, we consider that Gross Expenditure at
Surplus/deficit on Provision of Services is the key focus of users of the financial
statements. We have therefore determined our initial materiality levels using Gross
Expenditure at Surplus/deficit on Provision of Services as the benchmark.

Materiality and misstatements (continued)
21
Materiality (continued)
For the single-entity financial statements, we consider that Gross Expenditure at Surplus/deficit
on Provision of Services is the key focus of users of the financial statements. We have therefore
determined our initial materiality levels using Gross Expenditure at Surplus/deficit on Provision
of Services as the benchmark.
We expect to set a materiality of 2% of Gross Expenditure at Surplus/deficit on Provision of
Services for the consolidated financial statements, and a materiality of 2% of Gross Expenditure
at Surplus/deficit on Provision of Services for the single-entity.
As set out in the tables alongside, based on currently available information being the audited
23/24 financial statements, we anticipate overall materiality for the year ended 31 March 2025 to
be in the region of £11.588m (£11.588m in the prior year), and performance materiality (set at
70% of overall materiality) to be in the region of £8.112m (£8.112m in the prior year).
For the single-entity, we anticipate overall materiality for the year ended 31 March 2025 to be in
the region of £11.468m (£11.468m in the prior year), and performance materiality (set at 65% of
overall materiality) to be in the region of £7.454m (£6.881m in the prior year).
In determining the overall materiality levels, we made the following significant judgements;
• that the main users of the financial statements are the Scottish Government, other Local
Authorities, Regulators, Elected Members, Local Communities, and other Stakeholders;
• that the primary aggregate that users tend to focus on is gross revenue expenditure at
surplus/deficit level, as it reflects the extent of services delivered by the Council;
• that users of the financial statements and decision makers (the Council, Audit Committee
and Scottish Government) have an understanding of the inherent uncertainties around
accounting estimates and judgements;
• that setting 2% of the chosen benchmark is consistent with prior period and as part of our
audit, we have gained an understanding that the Council has a well established and
experienced finance team capable of applying the relevant accounting standards; and
• that Audit Committee members demonstrate an ability to scrutinise financial information at a
high level.

Trusts, we anticipate overall materiality for the year ended 31 March 2025 to be
in the region of £0.005m (£0.005m in the prior year), and performance
materiality to be in the region of £0.004m (£0.004m in the prior year).
We will continue to monitor materiality throughout our audit to ensure it is set at
an appropriate level.

We assess the Remuneration Report as sensitive

• For senior councillors and senior employees'
remuneration and pensions benefits, our specific
materiality will be £1,000.
• For other employees' remuneration, these are
disclosed in bands, hence we have set a specific
materiality of £5,000 which equates to one
banding. 
• For exit packages, we have set a specific
materiality of £50,000.

Materiality and misstatements (continued)
Misstatements
We will accumulate misstatements identified during our audit that are above our
determined clearly trivial threshold. 
We have set a clearly trivial threshold for individual misstatements we identify (a reporting
threshold) for reporting to Audit Committee and management that is consistent with a
threshold where misstatements below that amount would not need to be accumulated
because we expect that the accumulation of such amounts would not have a material
effect on the financial statements. 
Based on our preliminary assessment of overall materiality, our proposed clearly trivial
threshold is £348k for the Group and £344k for the single-entity, based on 3% of overall
materiality. If you have any queries about this, please raise these with the Engagement
Director, Tom Reid.
Each misstatement above the reporting threshold that we identify will be classified as:
• Adjusted: Those misstatements that we identify and are corrected by management.
• Unadjusted: Those misstatements that we identify that are not corrected by
management.
We will report all misstatements above the reporting threshold to management and request
that they are corrected. If they are not corrected, we will report each misstatement to Audit
Committee as unadjusted misstatements and, if they remain uncorrected, we will
communicate the effect that they may have individually, or in aggregate, on the financial
statements and on our audit opinion.
Misstatements also cover qualitative misstatements and include quantitative and
qualitative misstatements and omissions relating to the notes of the financial statements.
Reporting
In summary, we will categorise and report misstatements above the reporting threshold to
Audit Committee as follows:
• Adjusted misstatements;
• Unadjusted misstatements; and
• Disclosure misstatements (adjusted and unadjusted).

Significant risks and other key judgement areas
Definitions
Following the risk assessment approach set out in the ‘Audit scope, approach, and timeline’ section, we have identified the risks of material misstatement in the financial statements. These
risks are categorised as significant, enhanced, or standard. The definitions of these risk ratings are set out below.
25
Risk
Level
Definition
Significant A risk that is assessed as being at or close to the upper end of the spectrum of inherent risk, based on a combination of
the likelihood of a misstatement occurring and the magnitude of any potential misstatement. A fraud risk is always
assessed as a significant risk (as required by auditing standards), including management override of controls and
revenue recognition.
Enhanced An area with an elevated risk of material misstatement at the assertion level, other than a significant risk, based on
factors/ information inherent to that area. Enhanced risks require additional consideration but do not rise to the level of a
significant risk. These include but are not limited to:
• Key areas of management judgement and estimation uncertainty, including accounting estimates related to material
classes of transaction, account balances, and disclosures but which are not considered to give rise to a significant
risk of material misstatement; and
• Risks relating to other assertions and arising from significant events or transactions that occurred during the period.
Standard A risk related to assertions over classes of transaction, account balances, and disclosures that are relatively routine,
non-complex, tend to be subject to systematic processing, and require little or no management judgement/ estimation.
Although it is considered that there is a risk of material misstatement, there are no elevated or special factors related to
the nature of the financial statement area, the likely magnitude of potential misstatements, or the likelihood of a risk
occurring.

1 Management override of controls (applies to
Council and Group)
This is a mandatory significant risk on all audits
due to the unpredictable way in which such an
override could occur.
Management at various levels within an
organisation are in a unique position to perpetrate
fraud because of their ability to manipulate
accounting records and prepare fraudulent
financial statements by overriding controls that
otherwise appear to be operating effectively. Due
to the unpredictable way in which such override
could occur there is a risk of material
misstatement due to fraud on all audits. You
should assess this risk as part of your oversight of
the financial reporting process.
Yes No No In line with our methodology, we plan to address the management override of
controls risk for the Council through performing audit work over:
• accounting estimates: by evaluating the methods and assumptions used by
management to develop the estimate;
• journal entries: testing journals that meet our fraud risk criteria and other
adjustments made in preparing the financial statements; and
• significant transactions: considering and testing any significant transactions
outside the normal course of business or otherwise unusual.
For the group, we will review the consolidation adjustments made by officers in
preparing the group financial statements.
Audit risks and planned responses
In this section, we have set out the risks that we deem to be significant and enhanced, and our planned response. An audit is a dynamic process, and should we change our view of risk
and/ or our approach to address those risks during our audit, we will report this to Audit Committee.

2 Valuation of property, plant and equipment
(applies to the Council only)
The Council held land and buildings (including
council dwellings) with a net book value of
£1.07 billion at 31 March 2024. The Council
has adopted a rolling revaluation model with
other land and buildings revalued over a five-
year cycle. This may result in individual assets
not being revalued for several years. This
increases the risk of misstatement for those
assets that have not been revalued in recent
years.
Valuations are based on specialist and
management assumptions, with a high degree
of estimation. We have determined there is a
significant risk of material misstatement from
assumptions that are incorrect and/or not
supported by relevant evidence being applied.
No Yes Yes We will address this risk by:
• assessing the scope and terms of engagement with the Valuer;
• assessing the competence, skills and objectivity of the Valuer;
• assessing how management use the Valuer’s report to value land and buildings
included in the financial statements;
• testing the accuracy of the data used in valuations;
• challenging the Council and Valuer’s assumptions and judgements applied in the
valuations;
• reviewing the valuation methodology used, including the appropriateness of the
valuation basis;
• considering the reasonableness of the valuation by comparing the valuation output with
market intelligence;
• testing a sample of revaluations in the year, by agreeing the revaluations recorded in
the Annual Accounts to the Valuer’s reports. As part of this testing, we will check
whether the movements have been accounted for in accordance with the Code;
• challenging management’s assessment for those assets not subject to valuation in the
year;
• checking market movements to assess the materiality of potential movement for
2024/25 for those valued on Existing Use Value on a market comparable basis; and
• for those valued on a Depreciated Replacement Cost basis, which would be impacted
by changes in build costs during the year, we will test management’s analysis of
changes in the Build Costs Information Service (BCIS) index and assess any decisions
management make in this regard.

3 Valuation of the net defined benefit (liability)/
surplus (applies to the Council only)
The Council’s net defined benefit liability was £43
million as at 31 March 2024. Estimation of the net
pension asset or liability depends on several complex
judgements which are sensitive to changes. These
include the discount rate used, the rate at which
salaries are predicted to increase, inflation rates and
life expectancy. Due to the high degree of estimation
uncertainty associated with the valuations, we have
determined there is a significant risk in this area.
No Yes Yes In addressing this risk, we will:
• challenge the reasonableness of the Actuary’s assumptions that underpin the
relevant entries made in the financial statements;
• critically assess the competency, objectivity and independence of the
Actuary;
• liaise with the auditors of the Pension Fund Administrator to gain assurance
that the overall procedures and controls in place at the Pension Fund are
operating effectively;
• compare assumptions to expected ranges;
• review the accuracy and completeness of the membership data used by the
actuary in preparation of the Actuary’s valuation report;
• independently obtain confirmation of pension contributions, benefits paid and
any material transfers from the Pension Fund Administrator and compare
with the data used by the Actuary in the actuarial valuation; and
• agree data in the Actuary’s valuation report for accounting purposes to the
relevant accounting entries and disclosures in the Council’s financial
statements.

4 Application of the new accounting standard for
leases – IFRS 16 (applies to the Council only)
Effective from 1 April 2024, Local Authorities are
required to adopt the new International Financial
Reporting Standard, IFRS 16. This standard introduces
a ‘Right of Use’ asset category on the Balance Sheet,
along with the recognition of corresponding lease
liabilities. It applies to all types of leases, including
property, land, vehicles, plant, and equipment where
the Council is the Lessee.
IFRS 16 significantly changes how operating leases
are accounted for by requiring, for lessees, the
recognition of both assets and liabilities for rights and
obligations previously classified under operating
leases. Given the complexity of this accounting
standard, there is a risk that the Council may not have
a complete and accurate record of the leases it holds.
There is also a risk that the right-of-use asset and lease
liability may not have been correctly calculated on the
leases the Council has applied the standard to.
No Yes Yes We will address this risk by evaluating the design and implementation of
controls that the Council has in place over the adoption of the new standard.
In addition, we will :
• review procurement and contract registers for potential lease arrangements,
including embedded leases;
• perform inquiries with management about lease identification processes;
• substantively test the calculations of lease liabilities and right-of-use assets,
where material, to ensure these have been appropriately calculated in
accordance with the new accounting standard;
• review peppercorn and other leases requiring special consideration;
• compare assumptions to expected ranges;
• review the disclosures made in the financial statements to ensure they are
adequate, sufficient, and in line with the Code.

5 Liabilities From Service Concession Arrangements
(applies to the Council only)
The Council has a Public Private Partnership (PPP)
contract for the provision of three secondary schools and
one primary school, and a Design-Build-Finance-Maintain
(DBFM) contract for one secondary school. The contracts
include the build of the schools as well as their
maintenance and provision of related facilities over the
period of each contract.
The assets used to provide services at the schools are
recognised on the Council’s Balance Sheet as operational
assets and as a finance lease liability. The Council has
recognised an asset of £136 million and a liability of £86.4
million for PPP and DBFM in its 2023/24 annual accounts.
The Code, in implementing IFRS 16, requires local
authorities to remeasure their PPP liabilities as at 1 April
2024.
The method of accounting for service concession
arrangements can be complex and involves management
judgement. There is a risk of material misstatement if the
Council does not appropriately account for its service
concession arrangements.
No Yes Yes In addressing this risk, we will:
• update our understanding of the service concession arrangements at
the Council;
• review the inputs to current financial models to ensure they have
been appropriately updated and for any substantial changes;
• test material inputs into the model and agree outputs to the financial
statements;
• review the PPP models for remeasurement calculations or
management rationale for not remeasuring the liability in line with
IFRS 16; and
• review accounting policies and other related disclosures in the
financial statements to ensure they are in line with the Code.

Other considerations
In consideration of ISA (UK) 260 Communication with Those Charged with Governance, we would like to seek Audit Committee‘s views/ knowledge of the following matters:
• Did you identify any other risks (business, laws & regulation, fraud, going concern etc.) that may result in material misstatements?
• Are you aware of any significant communications between the Council and regulators?
• Are there any matters that you consider warrant particular attention during the course of our audit, and any areas where you would like additional procedures to be undertaken?
Significant difficulties encountered during the course of audit
In accordance with ISA (UK) 260 Communication with Those Charged with Governance, we are required to communicate certain matters to you which include, but are not limited to,
significant difficulties, if any, that are encountered during our audit. Such difficulties may include matters such as:
• Significant delays in management providing information that we require to perform our audit.
• An unnecessarily brief time within which to complete our audit.
• Extensive and unexpected effort to obtain sufficient appropriate audit evidence.
• Unavailability of expected information.
• Restrictions imposed on us by management.
• Unwillingness by management to make or extend their assessment of an entity’s ability to continue as a going concern when requested.
We will highlight to you on a timely basis should we encounter any such difficulties (if our audit process is unduly impeded, this could require us to issue a modified auditor’s report).
Internal audit function
Based on our assessment of the extent to which the internal audit function’s organisational status and relevant policies and procedures support the objectivity of the internal
auditors, the level of competence of the internal audit function, and whether the internal audit function applies a systematic and disciplined approach, including quality control, we do not
expect to use the work of the internal audit function for the purpose of our audit.
Nonetheless, we will obtain the reports issued by internal audit relating to the financial period under audit to determine whether any findings will have an impact on our risk assessment and
planned audit procedures.

Wider scope and Best Value
33
The framework for wider scope work
The Code of Audit Practice sets out the four areas that frame the wider scope of public sector audit. We are required to form a view on the adequacy of the Council’s arrangements in four
areas:
1. Financial management
2. Financial sustainability
3. Vision, leadership, and governance
4. Use of resources to improve outcomes
Financial
management
Financial management means having sound budgetary
processes. Audited bodies require the ability to understand the
financial environment and whether internal controls are
operating effectively.
Auditors consider whether the body has effective arrangements
to secure sound financial management.
Vision,
leadership and
governance
Audited bodies must have a clear vision and strategy, and set
priorities for improvement within this vision and strategy. They
work together with partners and communities to improve
outcomes and foster a culture of innovation.
Auditors consider the clarity of plans to implement the vision,
strategy and priorities adopted by the leaders of the audited
body. They also consider the effectiveness of governance
arrangements for delivery.
Financial
sustainability
Financial sustainability means being able to meet the needs of
the present without compromising the ability of future
generations to meet their own needs.
Auditors consider the extent to which audited bodies have
shown regard to financial sustainability. They look ahead to the
medium term (two to five years) and longer term (over five years)
to consider whether the body is planning effectively so that it can
continue to deliver services.
Use of
resources to
improve
outcomes
Audited bodies need to make best use of their resources to meet
stated outcomes and improvement objectives, through effective
planning and working with strategic partners and communities.
Auditors consider the clarity of the arrangements in place to
ensure that resources are deployed to improve strategic
outcomes, meet the needs of service users taking account of
equalities, and deliver continuous improvements in priority
services.

Wider scope and Best Value (continued)
34
Our approach
Our planned audit work against the four wider scope areas is risk based and proportionate. We need to gather sufficient evidence to support our commentary on the Council’s
arrangements and to identify and report on any significant weaknesses. We will carry out more detailed work where we identify significant risks. Where significant weaknesses are
identified we will report these to the Council and make recommendations for improvement. In addition to local risks, we consider challenges that are affecting the public identified,.
Best Value
Under the Code of Audit Practice, the audit of Best Value in councils is fully integrated within our annual audit work. We are required to consider the seven Best Value themes which are:
1. Vision and leadership
2. Governance and accountability
3. Effective use of resources
4. Partnerships and collaborative working
5. Working with communities
6. Sustainability
7. Fairness and equality
We are required to consider the Council’s arrangements in respect of the seven Best Value themes to identify any significant risks. Best Value at the Council will be assessed over the
period of the audit appointment. Where we identify risks or improvement areas we will plan appropriate coverage over the period of the audit appointment on a risk basis. We have not
identified any significant risks planned for coverage in 2024/25.
We will also follow up previously reported Best Value findings to assess the pace and depth of improvement. This work will be integrated into our audit approach, including our work on the
wider scope areas.
We will also conduct thematic reviews as directed by the Accounts Commission. In 2024/25 this will be on transformation. We will prepare a separate management report to document the
findings of this work.
At least once every five years, the Controller of Audit will report to the Accounts Commission on the Council’s performance in meeting its Best Value duties. The Council is not included in
the third year of the programme which runs from October 2025 to August 2026.

1 Financial sustainability
The council has forecasted significant cumulative
budget gaps rising from £9.2 million in 2025/26 to
£51 million in 2029/30. This is a potential risk to its
financial sustainability, and its ability to maintain its
services for the people of West Dunbartonshire.
No Yes No No We will review the Council’s:
• financial strategy;
• financial position and track record in delivering
planned recurrent and non-recurrent savings in
2024/25;
• financial performance in 2025/26 and updates
to its financial planning during the year,
including the implications for general reserves
balances;
• regular reporting to Members on financial
performance, savings plans and financial risks;
• progress in developing plans to address future
years’ budget gaps.

New standards and amendments
Effective for accounting periods beginning on or after 1 January 2023
Amendments to IAS 1 Presentation of Financial Statements and IFRS Practice
Statement 2 Making Materiality Judgements: Disclosure of Accounting Policies
(Issued February 2021)
• The amendments set out notable new requirements for accounting policy disclosures
that change the requirements for entities to disclose material accounting policy
information, rather than significant accounting policies, and not to disclose immaterial
accounting policy information, explaining that accounting policy information taken in
isolation is unlikely to be material, but it is when the information is considered together
with other information in the financial statements that may make it material. Earlier
application is permitted. The amendments have been UK-adopted and endorsed by the
EU.
Amendments to IAS 8 Accounting Policies, Changes in Accounting Estimates and
Errors: Definition of Accounting Estimates (Issued February 2021)
• The amendment introduces a new definition for accounting estimates and clarifies how
entities should distinguish changes in accounting policies from changes in accounting
estimates. The distinction is important because changes in accounting estimates are
applied prospectively only to future transactions and other future events, but changes in
accounting policies are generally applied retrospectively to past transactions and other
past events. Earlier application is permitted. The amendments have been UK-adopted
and endorsed by the EU.
IFRS 18 Presentation and Disclosure in Financial Statements (Issued April 2024)
• IFRS 18 Presentation and Disclosure in Financial Statements (IFRS 18) is a new
standard that replaces IAS 1 Presentation of Financial Statements. The new standard
aims to increase the comparability, transparency and usefulness of information about
companies’ financial performance. It introduces three key new requirements focusing on
the presentation of information in the statement of profit or loss and enhancing certain
guidance on disclosures within the financial statements.

International Auditing Standard UK 600 Revised - Special considerations - Audits of group financial statements (Including the work of component auditors)
ISA UK 600 deals with the special considerations that apply to audits of group financial statements, including those circumstances when component auditors are involved. The auditing
standard has been revised. The revised standard is effective for audits of group financial statements for periods beginning on or after 15 December 2023. The revisions made to ISA (UK)
600 impact how we perform audits of group financial statements, and how we communicate our audit strategy and audit findings arising from audits of group financial statements, going
forward. This page sets out the key changes made to ISA (UK) 600 and how Forvis Mazars will apply the requirements of the revised standard in practice.
Key changes
The previous ISA (UK) 600 included prescriptive requirements in respect of the audit procedures required over ‘significant components’ of a group, i.e., a ‘full scope’ audit of a significant
component’s financial information relevant to the group financial statements was required. Forvis Mazars defined a ‘significant component’ as one that contributed to the group financial
statements more than 15% of the materiality benchmark selected to determine group materiality, e.g., if we had determined materiality using a profit before tax benchmark, any
component that contributed more than 15% of the group’s reported profit before tax would be classified as a significant component and a ‘full scope’ audit would be performed over that
component’s financial information.
ISA (UK) 600 Revised eliminates the 'significant component' concept, opting instead for consideration of risks of material misstatement at the assertion level of the group financial
statements that are associated with components. This results in a group audit that is better focused on the risks of material misstatement of the group financial statements and affords
greater flexibility in how we classify components and how we may design the nature and extent of audit procedures to be performed over a component’s financial information, i.e., we can
determine the nature and extent of the audit procedures to be performed over a component’s financial information based on the specific risks relevant to the group financial statements.
ISA (UK) 600 also, however, removed the option to limit the procedures performed over a ‘non-significant’ component’s financial information to desktop analytical procedures. We are
now required to perform substantive audit procedures (or a combination of substantive audit procedures and tests of controls) over the group financial statements, including the financial
information relating to components in the group, until the residual, untested balances, classes of transaction and disclosures in the group financial statements are below our group
materiality. This is to ensure that aggregation risk (the probability that the aggregate of uncorrected and undetected misstatements exceeds materiality for the financial statements as a
whole) is addressed appropriately.
In combination, these changes may result in a change to the nature and extent of the audit procedures we perform over the financial information of components on a group audit
compared to previous years and may result in components that were not previously in scope of our group audit being brought into scope going forward to ensure that we address
aggregation risk appropriately.

Appendix B: Current year updates, forthcoming accounting & other issues (continued)
International Auditing Standard UK 600 Revised - Special considerations - Audits of group financial statements (including the work of component auditors)
Key changes (continued)
To ensure consistency of approach, Forvis Mazars will apply the definitions set out below when performing audits of group financial statements going forward:
Key component Material component Non-material component
Any component:
i.Which is greater or equal to 15% of the
benchmark chosen for calculating group
materiality (key by size); or
ii.Where the specific nature or circumstance of
its financial information make it likely to
include significant risks of misstatement of the
group financial statements (key by risk).
Any component, other than a key component,
that contributes to one or more group financial
statement areas an amount that is above group
financial statement materiality.
A component, that is not a key component or a
material component, that is scoped into a group
audit to reduce the risk of material
misstatement of the group financial statements
to an acceptably low level (based on size or
risk) in situations when, after assessing which
components are key components and material
components, the aggregate amount of a
financial statement area related to un-scoped
components is still above group financial
statement materiality.

Appendix B: Current year updates, forthcoming accounting & other issues (continued)
International Auditing Standard UK 600 Revised - Special considerations - Audits of group financial statements (including the work of component auditors)
Key changes (continued)
Definition of ‘component’ - The definition of ‘component’ has been revised to “an entity,
business unit, function or business activity, or some combination thereof, determined by the
group auditor for the purposes of planning and performing audit procedures in a group
audit”.
This provides clarity on how components may be identified in a group audit and may result
in a change to how we identify components on a group audit compared to previous years.
For example, we may group separate legal entities (e.g., subsidiaries) in a group based on
common characteristics (such as common management, common information systems, and
common geographical locations) and treat those components as a single component, when
appropriate to do so.
Common controls - The definition of ‘group-wide’ controls has been removed and we are
instead required to consider ‘common controls’, being controls that operate in a common
manner for multiple entities or business units.
This may assist us in grouping separate legal entities, business units, functions, or business
activities in a group into a single component for the purposes of a group audit; or it may
result in us grouping specific account balances or classes of transaction recorded by
individual legal entities, business units, functions, or business activities into a single
population for the purposes of our audit procedures.
For audits where we are adopting a controls-based audit strategy, this may result in
efficiencies, as we can rely on a single control for the purposes of the audits of more than
one component where that control is common to those components.
Definition of ‘engagement team’ - The definition of ‘engagement team’ has been revised
to include component auditors. While this change may seem inconsequential, it forms part
of the overall changes intended by ISA (UK) 600 Revised to enhance two-way
communication between the group auditor and component auditors during a group audit.
This will result in enhanced direction and supervision of component auditors by the group
auditor during a group audit.
Calculation of component materiality - The requirement to set overall materiality for a
component has been removed. We are now only required to determine component
performance materiality.
Other changes - ISA (UK) 600 Revised includes new and revised requirements and
application material that better aligns the standard with recently revised standards such
as ISQM (UK) 1, ISA (UK) 220, and ISA (UK) 315. The new and revised requirements
also strengthen our responsibilities related to professional scepticism, planning and
performing a group audit, two-way communications between the group auditor and
component auditors, and audit documentation. These changes are to encourage
proactive management of quality at the group engagement level and the component
level; reinforce the need for robust communication and interactions during a group audit;
and foster an appropriately independent and challenging sceptical mindset.
Scope of audit work to be performed over a component’s financial information -
Forvis Mazars will, going forward, determine the scope of work to be performed over a
component’s financial information on a group audit using the definitions set out below:
Full scope Specific scope
Group Engagement
Team Instructed
Procedures
Designing and performing
audit procedures on the
entire financial information
of a component.
Designing and performing
audit procedures on one
or more specified account
balances, classes of
transaction, and/ or
disclosures of a
component.
Performing specified audit 
procedures, as designed
and instructed by the
group engagement team.
