2.5 Public Benefit

2.5.1 Benefits from aims

The general public throughout the world benefit from a safe and well-designed infrastructure provided by the highly skilled members of the Institution. This has a knock-on effect benefitting the world economy by providing employers with employees (who are Institution members) having an internationally recognised specialist professional qualification.

Public benefit is also gained from the ongoing professional support provided to members to keep their knowledge and skills up to date and relevant.

2.5.2 Membership benefits

The Institution is a membership organisation and members’ annual subscriptions form a significant part of the Institution’s income, which is used to fund its activities for the public benefit. Members themselves receive benefits through the Institution’s dissemination of knowledge and best practice, and from their membership of a professional body with high standards of entry and continuing membership. However, it is only with and through its members that the Institution can continue to fulfil its objects and provide benefit to the public as a whole.

2.5.3 Charity Commission and OSCR Guidance

The Trustee Board has regard to guidance on public benefit published by the Charity Commission and that by the OSCR, when exercising its powers and duties and where such guidance is relevant. The Trustees have considered the Charity Commission’s and OSCR’s general guidance on public benefit and have taken it into account when reviewing the Institution’s aims and objectives and in planning its future activities.

3. Achievements and Performance

4. Financial Review 4.1 Trustees’ Responsibilities for the accounts and financial statements

The Charities Act 2011 and the Charities and Trustee Investment (Scotland) Act 2005, requires the Trustees to prepare financial statements for each financial year which give a true and fair value of the state of affairs of the charity at the end of the year and of the incoming and outgoing resources for the year then ended.

In preparing those financial statements, the Trustees are required to select suitable accounting policies and then apply them consistently, making judgements and estimates that are reasonable and prudent. The Trustees must also prepare the financial statements on the going concern basis, unless it is inappropriate to presume that the charity will continue its activities.

The Trustees are responsible for keeping proper accounting records which disclose with reasonable accuracy at any time the financial position of the charity and to enable them to ensure that the financial statements comply with the Charities Act 2011 and the Charities and Trustee Investment (Scotland) Act

ANNUAL REPORT AND ACCOUNTS

Page 7/42

1. The Trustees are also responsible for safeguarding the assets of the charity and hence taking reasonable steps for the prevention and detection of fraud and other irregularities.

The Trustees are satisfied that these requirements are being met.

4.2 Review of the year

The Group posted a surplus for the year ended 31st December 2023 of £89.7k (2022: £592k). Total Group income was £8.9m (2022: £8.6m), with £5m (2022: £5m) coming from members’ subscriptions and qualification fees and £3.9m (2022: £3.6m) from other sources including trading subsidiaries. Repayments on the mortgage (circa 11% of asset value) taken to fund the redevelopment of the building in Bastwick Street in 2014 and to support capital projects (including the ongoing Digital Transformation project), were fully discharged within the forecast cash flow parameters agreed by the Trustee Board and the Institution’s bankers.

Some 57% of the Institution Group’s income comes from membership and qualification activities; 2% from advertising and online income from The Structural Engineer; 16% from the trading activities of SER; 11% from publications sales, courses and conferences. The remaining 14% was derived from a range of activities across the charity and trading companies.

4.3 Reserves

At the end of 2023, the Institution had total Unrestricted Reserves of £11.6m. The majority of these are Designated Funds (£6.4m), in particular the Bastwick Street Fund (£4.5m), with General Funds of £5.2m. The remaining funds are made up of Restricted Funds of £263k and Permanent Endowment Funds of £33k.

The Institution uses two tests to monitor the adequacy of its Reserves – Free Reserves and Free Cash Reserves:

• Free Reserves are calculated using the total Unrestricted Funds, less Designated Funds (excluding the Bastwick Street Fund and the Mortgage Repayment Fund) and Fixed and Intangible Assets, adding back the loan used for the redevelopment of Bastwick Street. The Free Reserves position is monitored on an annual basis to ensure it is adequate and is in line with the Institution’s operational requirements at that time.

As at 31 December 2023, the Institution had Free Reserves of £2.2m (the comparable 2022 figure was £1.9m).

• The Free Cash Reserves policy was set in 2019 with the target that our free cash balances, representing the Institution’s bank accounts excluding those held for restricted purposes, should be equivalent to three months of expenditure, currently approximately £2.2m.

The minimum free cash balance figure during 2023 was £4.6m which is substantially higher than the target set by the Trustee Board. With the advance receipt of subscriptions for 2024, Free Cash Reserves were £5.7m as at 31st December 2023.

4.4 Funds

The Institution’s restricted and designated funds are described in notes 18 and 19 to the Financial Statements, respectively.

ANNUAL REPORT AND ACCOUNTS

Page 8/42

The Trustee Board decides on a year-by-year basis the amounts that are placed in each designated fund and monitors actual income and expenditure against the operating forecast.

4.5 Final Salary Pension Scheme

The Institution has, in prior years, contributed to the Institution of Structural Engineers (1973) Pension and Life Assurance Scheme (‘the Scheme’) at rates set by the Scheme Actuary and as advised to the Trustees by the Scheme Administrator. In accordance with FRS102, the Scheme is accounted for as a defined benefit scheme.

In the period to November, 2021, the Institution concluded a Buy-in arrangement with Legal & General (‘L&G’) which resulted in the Scheme’s assets being transferred to L&G. The transferred assets comprise the insured annuities for the value of member benefits under FRS102. At this point, L&G assumed responsibility for making the payments due to the members of the Scheme, with the Institution retaining the legal responsibility for the payment of all member benefits.

The Institution is working with L&G and the Scheme members to agree a Buy-out arrangement where the members will have a direct legal relationship with L&G who will then take responsibility for paying pensions directly to each individual Scheme member. It is expected that this buy-out arrangement will be concluded in 2024.

With the completion of the Buy-in:

• effective December 2021 the Institution has made no further contributions into the Scheme, although it continues to meet the costs of administering and operating the Scheme;

• and, in line with the accounting policy adopted in last year’s financial statements for the year ending December 31, 2021, the Institution has chosen not to recognise within its Balance Sheet any deficit or surplus on the Scheme calculated under FRS 102.

In addition, within Designated Funds, the Institution holds an Employee Pensions Fund of £59.6k (2022 £157.3k) to cover the ongoing costs of the Scheme including the cost of completing the Buy-out arrangement.

Full information on the Final Salary Pension Scheme is given in Note 22 to the Financial Statements.

4.6 Grant making policy

4.6.1 The Institution and Regional Group Awards

As a learned society, the Institution has a vision to lead, support and nurture the development of structural engineering worldwide by upholding high standards, building knowledge communities, and promoting structural engineering. In furtherance of this vision the Institution encourages its members to pursue excellence in their work and contribution to the profession and wider society. The Institution celebrates outstanding contributions from structural engineers and awards are given each year to members and nonmembers for the technical papers, presentations at meetings in the regional groups, for the best students at higher educational establishments in regional areas, and for newly built/refurbished structures. Each of these award winners receive a certificate. Some also receive a plaque or a financial reward (in the £50-£200 range).

ANNUAL REPORT AND ACCOUNTS

Page 9/42

4.6.2 Research Fund

The Institution’s Research Fund (administered by the Research Panel, which reports to the Structural Futures Committee) makes grants to support research in structural engineering in both industry and academia, including at undergraduate and master’s level. It also supports young researchers through the annual Young Researchers’ Conference.

5. Plans for Future Periods

5.1 Long and medium-term strategy

The Institution Trustee Board approved a strategy to guide its direction of travel from 2015 to 2020 and to inform the longer-term period to 2025. The strategy is supported by a rolling 5-year business plan. In summary the strategy is two-fold:

• An Institution committed to competency.

• An Institution founded on communities.

As a long-term strategy, the Institution has a vision that consolidates its existing position as the leading international specialist professional body for structural engineers committed to supporting the wellbeing of society through activities that assist structural engineers acquire, maintain, and develop the necessary competencies to practice.

The Institution has also identified engineering themes that it can champion to promote dialogue both internally and externally with audiences that extend beyond its own current constituency of structural engineers. The broad areas of interest are:

• Safety of society.

• Sustainability of society and the Climate Emergency.

• Value to society.

The Institution’s continued major programme of digital transformation is a critical component of connecting a worldwide cohort of engineers. Development of the Institution’s web platforms increases the ability to access and share relevant information between member communities that may be founded on areas of common interest, need and expertise.

5.2 Looking ahead to 2024

The Trustee Board has endorsed a programme of objectives for 2024 in support of the strategic plan. These include the following activities:

• [The continuation of investment in responding to the climate and biodiversity emergency.]

6 Structure, Governance and Management

6.1 Organisational Structure

The Institution was founded in 1908 and was incorporated by Royal Charter on 4 May 1934; the current Supplemental Charter, with associated Bye-laws, was granted on 1 December 2004. The Charter empowers the Trustee Board to make Regulations relating to the Institution and for the conduct of members. They are kept under review and were last amended during 2023.

The Institution’s activities are conducted through the Institution itself and also through its two wholly owned subsidiaries - IStructE Ltd and Structural Engineers Registration Ltd (SER).

Structural Safety Ltd (SSL), jointly owned with The Institution of Civil Engineers, brings together the activities of SCOSS (Standing Committee on Structural Safety) and CROSS (Collaborative Reporting on Safer Structures).

To support its international development activities, the Institution has legal entities registered in Hong Kong and the United Arab Emirates. IStructE (Asia-Pacific) Limited and IStructE FZ LLC respectively.

Collectively all these companies are referred to as ‘the Institution Group’.

Authority to conduct the day-to-day operations of the Institution is delegated by the Trustee Board to the Chief Executive, who is responsible to the Trustee Board for the efficient running of the Institution and for the implementation of policies and strategies. The Chief Executive and the Deputy Chief Executive along with the Trustee Board Secretary, work with and support the Trustee Board in the fulfilment of their obligations as Trustees. The Senior Management Team (SMT) supports the Chief Executive and has operational and delivery responsibility for the Institution’s membership, product, and services activities.

Council (which includes members elected by, and from, Chartered and Incorporated Structural Engineers, Associates, Technician Members and Graduates worldwide, as well as regional group Chairs, representatives from the Headline Committees and other co-optees) support the Trustee Board in determining the core values and strategic aims of the Institution. Although its role is essentially advisory and consultative, it debates and influences policies, offers advice to the Trustee Board, and, in each year where elections take place, it elects the President and President-Elect and elects Council members to the Nominations Committee.

6.2 Governance

The Trustee Board Chair is chair of the Board of Trustees, which comprises 11 other members including ex officio the President. Vice-Presidents are elected from 5 world electoral regions and serve a term of three years; other members of the Trustee Board are elected by and from the world-wide voting membership. Each year, Council ratifies the recommendations made by the Nominations Committee for those standing for election for Vice-President, Trustee Board Member and Ordinary Member of Council.

The Trustee Board may invite specialist advisers to attend, and relevant members of the Senior Management Team also attend . Such persons do not thereby become members of the Trustee Board and may not vote on any matter to be decided by it.

ANNUAL REPORT AND ACCOUNTS

Page 12/42

The Institution’s ‘session’ commenced on 1 January 2023; when the incoming Trustee Board Chair, President and members of the Trustee Board, the Council and committees took office. The session ran to 31 December 2023. At the first meeting of the session, Trustee Board members received training in trusteeship.

At the end of the session, the Trustee Board members self-evaluated their individual performance during the year and that of the Trustee Board. The collective output was discussed by the Trustee Board and as necessary, action plans developed so that improvements may be affected.

6.3 Management

The Professional Conduct Committee keeps the code of conduct, guidance notes and disciplinary procedures under review, and investigates allegations of misconduct made against members and also misrepresentations relating to Institution membership.

The Nominations Committee makes annual recommendations to the Council concerning the election of the President, President-Elect and co-options to Council, and also the appointment of Past-President to Council. The Committee is responsible for the appointment of the Trustee Board Chair, and it also adjudicates on Institution Awards made to individuals.

Panels, which deal with specific areas of activity, report as shown on page 14.

6.3.2 Regional Groups

Institution members throughout the world, where there are sufficient concentrations of members, are allocated to regional groups. Such regional groups are run by committees, which arrange learned society, continuing professional development and networking events, to complement those organised by the Institution centrally. Each group has regulations for its governance, which have been approved by the Trustees. The financial activities of these groups form part of the 2023 annual statement.

6.3.3 Staff

The average number of staff employed during the year to 31 December 2023 was 65 (a slight increase on the average number of 62 staff employed during 2022). The staff organogram is on page 15.

The staff have adopted the following mission statement as the focus of their aspirations:

6.3.8 Risk Management

The Trustee Board acknowledges its responsibility for managing the risks to which the Institution is exposed. It oversees an on-going assessment of the major risks – in particular those relating to strategic objectives, operations, finances and reputation. Control systems are in place to manage those risks.

The responsibility for providing guidance to the Trustee Board on matters relating to finance and operational risk is delegated to the Resources Committee. Strategic and reputational risk matters are primarily under the direction of the staff directorate and discussed at regular intervals with the Trustee Board.

The principal risks facing the Institution, with the key actions in place to mitigate against them are:

• [Reduction in membership – Income from membership subscriptions is key to the Institution. In order to] mitigate against a reduction in the number of members as the result of demographic factors and also to seek to grow the membership, the Institution has introduced initiatives including:

• [An increased range of products and services including CPD course provision, on-line courses, books] and other publications; the library and a growing portfolio of e-books and an events program.

• [Increased focus and support for young][member events.]

• [Increasing the number of candidates eligible to proceed to Chartered Membership] (MIStructE/FIStructE) by mapping the examinations offered by other international structural engineering bodies against the Institution’s examinations and introducing supplementary examinations to assess those areas that are not tested.

• [Improving accessibility to professional membership by introducing flexibility in how candidates may] satisfy the Master’s level academic requirement.

• [Introducing the membership postnominal GIStructE for those graduate members who have] successfully completed the Certificate in Structural Behaviour.

• Introducing Bye-Law changes whereby whereby graduate members who have satisfied the Institution's academic requirements and passed the Chartered Professional Review Interview are able to register as Associates (AIStructE) with the Institution and Chartered Engineers (CEng) with the Engineering Council.

• Data Protection – The Institution’s operations are heavily reliant on the use of the personal data of both members and non-members. A risk-based approach to data security is taken and appropriate technical and organisational measures are in place including:

• Further to the introduction of the General Data Protection Regulation in May 2018 all associated policies and procedures continue to be reviewed and updated as necessary.

• Encryption of server systems.

• Development of a new Cyber security Institution framework and working towards Cyber Essentials accreditation (accreditation achieved March 2023).

• Mandatory training provided to all staff on data security and guidance provided to Regional Groups.

• Resilience of commercial revenue – In order to reduce reliance on income from membership subscriptions a number of revenue streams, have, and continue to be developed through IStructE Ltd.

• [Throughout 2022 and into 2023 a greater number of online products have been created and delivered,] greatly increasing the available portfolio and meeting the varying delivery requirements of members and other users.

ANNUAL REPORT AND ACCOUNTS

Page 17/42

• [Reduction in income from Structural Engineers Registration Ltd (SER) – Income from SER is largely] linked to the level of activity in the Scottish construction industry which is outside the company’s control. A prudent approach is therefore taken to budgeting.

• [Loss of multiple key personnel. Loss of staff is a risk in any organisation and will occur, however the] Institution structure and ways of working are such that knowledge does not generally reside in one person. Creation of a Senior Management Team (SMT) enabling the better sharing of knowledge across the senior management adds a further level of robustness.

• Volunteer engagement – the Institution is heavily dependent on the voluntary contribution of its members particularly in areas of technical and engineering knowledge sharing. Members give their time freely and willingly however conflicting pressures in the workplace and personal life means that the Institution is always looking to increase the number of members actively engaged with its activities.

• The increased use of technology and the flexibility that this entails, in terms of conducting meetings and other Institution activities at different times of the day, has led to a significant increase in member and volunteer engagement. This process has been accelerated by the Covid pandemic and the Institution will continue to incorporate the positive learning points from the last four years into future plans.

• [Increase in staff costs – As with most membership organisations the Institution’s employee related costs is] the key component of total expenditure. The risks associated with staff costs are managed through a rigorous annual budgeting process and close scrutiny to confirm the business need for any additional staff costs.

• Increases in the cost of capital expenditure – Where projects involving significant capital expenditure are undertaken there is likely to be an increased risk of cost escalation. Mitigation measures include development of detailed project specifications before work commences and appropriate levels of project management including formation of Project Oversight Trustee Boards, for example the Digital Transformation Board.

• [Health and safety – presenting reputational and legal risks as well as the primary risk to the safety and] health of staff and others, the Institution takes this risk area seriously.

• [A health and safety policy is in place together with supporting documents and appropriate procedures.] Health and safety is overseen by the Head of Human Resources who chairs a staff health and safety committee that meets quarterly.

• [Staff working from home have been supplied with guidance for safe working and regular communication] and surveys of staff have been undertaken.

6.3.9 Fundraising

Section 162a of the Charities Act 2011 requires charities to make a statement regarding fundraising activities. Although the Institution does not undertake widespread fundraising from the general public, the Charities Act 2011 defines fund raising as ‘soliciting or otherwise procuring money or other property for charitable purposes’, and the Charities and Trustee Investment (Scotland) Act 2005 , definition includes ‘ representing and soliciting in any manner, whether expressly or implied… for a body established for charitable, benevolent or philanthropic purposes’.

Such amounts receivable are presented in the Institution’s accounts as ‘donations and legacies’.

ANNUAL REPORT AND ACCOUNTS

Page 18/42

In relation to the above the Trustees confirm that all solicitations are managed internally, without involvement of commercial participators or professional fund-raisers, or third parties. The day-to-day management of all income generation is delegated to the staff directorate, all of whom are accountable to the Trustees.

The Institution is not subject to any undertaking to be bound by any regulatory scheme and does not consider it necessary to comply with any voluntary code of practice. No complaints have been received by the Institution in relation to fundraising activities. The Institution’s terms of employment require staff to behave reasonably at all times and, as it does not approach individuals for funds it does not particularise this to fundraising activities nor is it considered necessary to design specific procedures to monitor such activities.

Independent auditor’s report to the trustees of the Institution of Structural Engineers

Opinion

We have audited the financial statements of the Institution of Structural Engineers for the year ended 31 December 2023 which comprise the consolidated statement of financial activities, the balance sheets, the consolidated statement of cash flows and notes to the financial statements, including a summary of significant accounting policies. The financial reporting framework that has been applied in their preparation is applicable law and United Kingdom Accounting Standards, including Financial Reporting Standard 102 The Financial Reporting Standard applicable in the UK and Republic of Ireland (United Kingdom Generally Accepted Accounting Practice).

In our opinion, the financial statements:

• give a true and fair view of the state of the group’s and of the parent charity’s affairs as at 31 December 2023 and of the group’s net movement in funds for the year then ended;

• have been properly prepared in accordance with United Kingdom Generally Accepted Accounting Practice; and

• have been prepared in accordance with the requirements of the Charities Act 2011 and the Charities and Trustee Investment (Scotland) Act 2005 and regulation 8 of the Charities Accounts (Scotland) Regulations 2006.

Basis for opinion

We have been appointed as auditor under section 144 of the Charities Act 2011, and section 44(1)(c) of the Charities and Trustee Investment (Scotland) Act 2005 and report in accordance with the Acts and relevant regulations made or having effect thereunder. We conducted our audit in accordance with International Standards on Auditing (UK) (ISAs (UK)) and applicable law. Our responsibilities under those standards are further described in the Auditor’s responsibilities for the audit of the financial statements section of our report. We are independent of the group in accordance with the ethical requirements that are relevant to our audit of the financial statements in the UK, including the FRC’s Ethical Standard, and we have fulfilled our other ethical responsibilities in accordance with these requirements. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.

Conclusions relating to going concern

In auditing the financial statements, we have concluded that the trustees’ use of the going concern basis of accounting in the preparation of the financial statements is appropriate.

Based on the work we have performed, we have not identified any material uncertainties relating to events or conditions that, individually or collectively, may cast significant doubt on the group’s ability to continue as a going concern for a period of at least twelve months from when the financial statements are authorised for issue.

Our responsibilities and the responsibilities of the trustees with respect to going concern are described in the relevant sections of this report.

Other information

The other information comprises the information included in the annual report, other than the financial statements and our auditor’s report thereon. The directors are responsible for the other information. Our opinion on the financial statements does not cover the other information and, except to the extent otherwise explicitly stated in our report, we do not express any form of assurance conclusion thereon. In connection with our audit of the financial statements, our responsibility is to read the other information and, in doing so, consider whether the other information is materially inconsistent with the financial statements or our knowledge obtained in the audit or otherwise appears to be materially misstated. If we identify such material inconsistencies or apparent material misstatements, we are required to determine whether there is a material misstatement in the financial statements or a material misstatement of the other information. If, based on the work we have performed, we conclude that there is a material misstatement of this other information, we are required to report that fact. We have nothing to report in this regard.

Matters on which we are required to report by exception

We have nothing to report in respect of the following matters in relation to which the Charities (Accounts and Reports) Regulations 2008 and the Charities Accounts (Scotland) Regulations 2006 require us to report to you if, in our opinion:

• adequate accounting records have not been kept by the parent charity, or returns adequate for our audit have not been received from branches not visited by us; or

• sufficient and proper accounting records have not been kept; or

• the parent charity financial statements are not in agreement with the accounting records and returns; or

• • we have not received all the information and explanations we require for our audit.

Responsibilities of trustees for the financial statements

As explained more fully in the trustees’ responsibilities statement set out on page 6, the trustees are responsible for the preparation of the financial statements and for being satisfied that they give a true and fair view, and for such internal control as the trustees determine is necessary to enable the preparation of financial statements that are free from material misstatement, whether due to fraud or error.

In preparing the financial statements, the trustees are responsible for assessing the group’s and the parent charity’s ability to continue as a going concern, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless the trustees either intend to liquidate the group or the parent charity or to cease operations, or have no realistic alternative but to do so.

Page 21 /42

Auditor’s responsibilities for the audit of the financial statements

Our objectives are to obtain reasonable assurance about whether the financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue an auditor’s report that includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducted in accordance with ISAs (UK) will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these financial statements.

Irregularities, including fraud, are instances of non-compliance with laws and regulations. We design procedures in line with our responsibilities, outlined above, to detect material misstatements in respect of irregularities, including fraud. The extent to which our procedures are capable of detecting irregularities, including fraud is detailed below:

Based on our understanding of the group and the environment in which it operates, we identified that the principal risks of non-compliance with laws and regulations related to charity law applicable in both England and Wales and Scotland, and we considered the extent to which non-compliance might have a material effect on the financial statements. We also considered those laws and regulations that have a direct impact on the preparation of the financial statements such as the Charities Act 2011.

We evaluated management’s incentives and opportunities for fraudulent manipulation of the financial statements (including the risk of override of controls). Audit procedures performed by the engagement team included:

• Discussions with management including consideration of known or suspected instances of non-compliance with laws and regulation and fraud;

• Reviewing the controls and procedures of the group relevant to the preparation of the financial statements to ensure these were in place throughout the year, including during the Covid-19 remote working period;

• Evaluating management’s controls designed to prevent and detect irregularities;

• Identifying and testing journals, in particular journal entries posted with unusual account combinations, postings by unusual users or with unusual descriptions; and

• Challenging assumptions and judgements made by management in their critical accounting estimates, in particular the valuation of intangible assets and debt provisions.

• Reviewing the assumptions and judgements used by the professional actuary in relation to the Charity’s pension asset.

Because of the inherent limitations of an audit, there is a risk that we will not detect all irregularities, including those leading to a material misstatement in the financial statements or non-compliance with regulation. This risk increases the more that compliance with a law or regulation is removed from the events and transactions reflected in the financial statements, as we will be less likely to become aware of instances of non-compliance. The risk is also greater regarding irregularities occurring due to fraud rather than error, as fraud involves intentional concealment, forgery, collusion, omission or misrepresentation.

A further description of our responsibilities for the audit of the financial statements is located on the Financial Reporting Council’s website at: www.frc.org.uk/auditorsresponsibilities. This description forms part of our auditor’s report.

Use of our report

This report is made solely to the charity’s trustees, as a body, in accordance with section 144 of the Charities Act 2011 and regulations made under section 154 of that Act, and section 44(1)(c) of the Charities and Trustee Investment (Scotland) Act 2005 and regulation 10 of the Charities Accounts (Scotland) Regulations 2006. Our audit work has been undertaken so that we might state to the charity's trustees those matters we are required to state to them in an Auditor's report and for no other purpose. To the fullest extent permitted by law, we do not accept or assume responsibility to anyone other than the charity’s trustees as a body for our audit work, for this report, or for the opinions we have formed.

Notes to the accounts

Year ended 31 December 2023

1. Accounting policies

Basis of preparation

The accounts (financial statements) have been prepared in accordance with the Statement of Recommended Practice: Accounting and Reporting by Charities preparing their accounts in accordance with the Financial Reporting Standard applicable in the UK and Republic of Ireland (FRS 102) issued on 16 July 2014 and the Financial Reporting Standard applicable in the United Kingdom and Republic of Ireland (FRS 102) and the Charities Act 2011 and UK Generally Accepted Practice as it applies from 1 January 2015.

The accounts (financial statements) have been prepared to give a ‘true and fair’ view and have departed from the Charities (Accounts and Reports) Regulations 2008 only to the extent required to provide a ‘true and fair view’. This departure has involved following Accounting and Reporting by Charities preparing their accounts in accordance with the Financial Reporting Standard applicable in the UK and Republic of Ireland (FRS 102) issued on 16 July 2014 rather than the Accounting and Reporting by Charities: Statement of Recommended Practice effective from 1 April 2005 which has since been withdrawn.

The Institution of Structural Engineers meets the definition of a public benefit entity under FRS 102. Assets and liabilities are initially recognised at historical cost or transaction value unless otherwise stated in the relevant accounting policy note(s).

Assessment of going concern

The Trustees have assessed whether the use of the going concern assumption is appropriate in preparing these financial statements. The Trustees have made this assessment in respect to a period of one year from the date of approval of these financial statements. The Trustees have considered the key risks and uncertainties facing the Charity and regularly review budgets and forecasts, including cash flows, and other key performance indicators. Budgets and forecasts consider the mitigating actions the Charity can deploy and consider both immediate liquidity and longer-term solvency, together with the impact on reserves.

The Trustees have concluded that there are no material uncertainties related to events or conditions that may cast significant doubt on the ability of the Charity to continue as a going concern. The Trustees are of the opinion that the Charity will have sufficient resources to meet its liabilities as they fall due.

Basis of consolidation

The financial statements include the consolidation of IStructE Limited, Structural Engineers Registration Limited, IStructE (Asia Pacific) Limited and CROSS-AUS Limited (wholly owned subsidiaries of the Institution) and IStructE FZ LLC (a subsidiary of IStructE Ltd) on a line by line basis. Structural-Safety Limited, a 50% owned subsidiary, is accounted for by including 50% of the net assets. The financial statements of a connected charity, The Institution of Structural Engineers Benevolent Fund, has not been included within the group consolidation.

Income

All income is recognised in the Statement of Financial Activities when the conditions for receipt have been met and receipt is probable. The following accounting policies are applied to income:

Donations and grants

Donations and grants are included in the financial statements when the conditions of receipt have been met.

Trading activities

Income from publishing, recruitment, catering, room hire and training

Turnover is recognised when the event, product or service has been delivered and the Group has fulfilled its contractual obligations.

Certification and renewal fees

The income from certification fees is recognised on receipt of payment while renewal fees are held as deferred income and allocated to the year to which they relate.

Charitable fees

Members’ subscriptions and fees

Members’ subscriptions and fees due are treated as income when receivable. Amounts received in respect of future years are held as deferred income and allocated to the year to which they relate.

Examinations and professional review fees

The income is recognised in the accounts in the month in which the examination is held with amounts received in advance held as deferred income. Income from professional review interviews is recognised on receipt.

Investment income and gains

Investment income, including any tax recoverable thereon, is included in the financial statements in the year in which it is receivable. The income from the joint venture (Structural-Safety Limited) is recognised as the service is provided based on 50% of the net assets of the Company.

Page 27 /42

Expenditure

Expenditure is recognised once there is a legal or constructive obligation to make a payment to a third party, it is probable that settlement will be required and the amount of the obligation can be measured reliably and includes irrecoverable Value Added Tax. Expenditure has been allocated on the basis indicated below:

Cost of raising funds

This cost category includes the cost of books sold and the operating costs of the trading subsidiaries.

Charitable activities

This includes all expenditure directly related to the objects of the charity.

Membership and qualification activities

This comprises the costs involved in providing support and services to the members of the Institution.

Technical & professional learning and development

This comprises the costs related to the advancement and development of structural engineering.

Other charitable activities

This comprises the costs of training members and events.

Support costs

These costs represent the staffing and associated costs of finance, IT, the general building and administration costs and governance costs in supporting the operational activities for which the charity is responsible. Governance costs include external audit, legal advice to the Trustees and costs associated with the Board. These are allocated as detailed in Note 4. The method of allocating support costs is based on headcount using FYE (full year equivalents) to full-time posts, irrespective of whether these posts are filled by permanent or temporary staff.

Fund accounting

The charity maintains various types of funds as follows:

Permanent endowment funds

These funds have been received by the Institution with specific restrictions on their use within the objectives of its Royal Charter and from which the income arising is available for fulfilment of those objectives. These funds comprise various prize funds.

Restricted funds

These funds have been received by the Institution with specific restrictions on their use within the objectives of its Royal Charter.

Unrestricted funds

These are available for the Institution to pursue its objectives under its Royal Charter and comprise:

Designated funds

Designated funds are amounts which have been put aside at the discretion of the Trustees. General unrestricted funds represent funds which are expendable at the discretion of the Trustees in the furtherance of the objects of the charity under its Royal Charter.

General fund

This represents the undesignated accumulated surpluses from funds available for the general objectives of the Institution.

Intangible assets

The assets in this category contain the historical cost less amortisation to date of the Institution’s websites and customer relationship management system (CRM). The cost is written off on a straight-line basis at 16.67% per annum.

Tangible fixed assets

Fixed assets are stated at historical cost less depreciation. Equipment renewals due to technological changes are charged to the Statement of Financial Activities. Depreciation is provided at rates calculated to write off the costs less land and estimated residual value on a straight-line basis over their estimated useful lives as follows:

Freehold premises 2% per annum on cost

Computers 33.3% per annum on cost

Furniture and equipment 16.67% per annum on cost

Investments in subsidiaries

Investments in subsidiaries are shown at cost. Investments in non-charitable companies under a joint venture arrangement are included at fair value, which is the Group’s share of the net assets of the commercial company at the balance sheet date.

Page 28 /42

Stock

Finished stock and work in progress relates to technical publications and is stated at the lower of cost and net realisable value. Cost comprises the price of purchasing, compilation, printing and binding.

Cash at bank and in hand

Cash at bank and in hand includes cash and bank deposits.

Pension contributions

The Institution operates two pension schemes as follows:

Final salary pension scheme

This scheme provides benefits based on final pensionable salary. The scheme was closed during 2002 and future pension arrangements were provided through a group personal pension plan. The assets of the final salary scheme are invested and are totally separate from those of the Institution. Contributions to the scheme are charged to income and expenditure to spread the cost over the employees’ working lives with the Institution. These contributions are determined by a qualified actuary on the basis of triennial valuations using the projected unit method. In accordance with FRS102 a Pension surplus is recognised under certain conditions. Since December 2021, no contributions have been made into this Scheme. A full update on the Final Salary Pension Scheme is given in note 22 below.

Group personal pension plan

The plan provides benefits based on contributions made and investment returns. The plan commenced during 2002 following the closure of the final salary scheme. Both the Institution and employees contribute to this plan. The assets of the plan are held in individual polices for each employee and invested and are totally separate from those of the Institution. Contributions to the plan are charged to income and expenditure as incurred. During 2015, new and existing employees who are not in the plan were automatically enrolled unless they have exercised their right to opt out.

Leases

Rental costs under operating leases are charged to the Statement of Financial Activities in equal amounts over the periods of the lease.

Financial instruments

The Institution only has financial assets and financial liabilities of a kind that qualify as basic financial instruments. Basic financial instruments are initially recognised at transaction value and subsequently measured at their settlement value with the exception of bank loans which are subsequently measured at amortised cost using the effective interest method. This is referred to in Note 16.

Current and deferred tax

The tax expense for the year comprises current and deferred tax. The current tax charge is calculated on all taxable income on the basis of tax rates and laws that have been enacted at the reporting date. Deferred tax is recognised in respect of all timing differences that have originated but not reversed at the balance sheet date.

Critical accounting judgements and estimation uncertainty

Estimates and judgements are continually evaluated and are based on historical experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances. The estimates and assumptions that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year are detailed below:

Useful economic lives of tangible and intangible assets

The annual depreciation and amortisation charge for fixed assets is sensitive to changes in estimated useful economic lives of the assets. The useful economic lives are re-assessed annually and are amended where necessary to reflect current estimates, based on technological advancement, future investments, economic utilisation and the physical condition of the assets.

Final salary pension scheme asset

The determination of the assumptions used in calculating the final salary pension scheme asset is the responsibility of the Trustees. The assumptions are set with regard to advice given by the scheme actuary (see note 22). In this context, significant judgement is exercised in a number of areas, including future changes in salaries and inflation, mortality rates and the selection of appropriate discount rates. Furthermore, a roll forward approach which projects results from the latest full actuarial valuation performed at 31 December 2019 has been used by the actuary in valuing the pension asset at 31 December 2023.

The Institution has de-risked its exposure to fluctuations in the final salary pension scheme valuation by entering into a “buy-in” arrangement. Whilst the liabilities of the scheme legally sit with the Institution, the buy-in arrangement ensures it is backed at all times, by an insurance asset, see note 22 for further details.

Allocation of support costs

Judgement is exercised in determining the appropriate basis to use for each category of support cost when apportioning those costs to the activities within raising funds and charitable activities. Details of the method of apportionment are included within note 4.

Foreign currency

Transactions in foreign currencies are recognised at the rate of exchange at the date of the transaction. Any exchange differences are recognised through the statement of financial activities. Foreign exchange monetary assets and liabilities are recognised at the rate of exchange ruling at the balance sheet date.

16. Financial instruments (continued)

In November 2019, the Board approved an extension to the loan, increasing it to £1.4m, which equals the amount borrowed in 2014. The loan is for 5 years but has a 10- year profiling, which explains why it is fully repayable at the end of 5 years, although rather than a balancing payment, at the end of the 5 years, an additional 5 years will be added to the loan in line with the profile agreed with Barclays Bank. The rate of interest is fixed at 3.86% for the first 5 years, to be repaid in equal instalments until December 2024. At the end of the 5[th] year the rate of interest will be re-negotiated on the amount outstanding for the final 5 years. The purpose of the loan is to finance the business transformation projects planned over the next 5 years. The ratio for the loan to property is 11% (2022: 12%).

22. Final salary pension scheme

The Institution has, in prior years, contributed to the Institution of Structural Engineers (1973) Pension and Life Assurance Scheme (‘the Scheme’) at rates set by the Scheme Actuary and as advised to the Trustees by the Scheme Administrator. In accordance with FRS102, the Scheme is accounted for as a defined benefit scheme. The last full actuarial valuation was completed as at 31[st] December 2022 on 27[th] March 2024.

In the period to November, 2021, the Institution concluded a Buy-in arrangement with Legal & General (‘L&G’) which resulted in the Scheme’s assets being transferred to L&G. The transferred assets comprise the insured annuities for the value of member benefits under FRS102. At this point, L&G assumed responsibility for making the payments due to the members of the Scheme, with the Institution retaining the legal responsibility for the payment of all member benefits.

The Institution is working with L&G and the Scheme members to agree a Buy-out arrangement where the members will have a direct legal relationship with L&G who will then take responsibility for paying pensions directly to each individual Scheme member. It is expected that this buy-out arrangement will be concluded in 2024.

With the completion of the Buy-In:

• Effective December, 2021 the Institution has made no further contributions into the Scheme, although it continues to meet the costs of administering and operating the Scheme;

• And, in line with the accounting policy adopted in last year’s financial statements for the year ending December 31, 2022, as the deficit or surplus calculated under FRS 102 can vary greatly from year to year depending on the assumptions made at the valuation date, the Institution has chosen not to recognise within its Balance Sheet any deficit or surplus on the Scheme calculated under FRS 102.

The information prepared below on the Scheme’s assets and liabilities should be read in the context of the existing buy-in arrangement and of the proposed buy-out arrangement.

The assumptions which had the most significant effect on the results of the valuation are those relating to the return on investments and the discount rate used to derive the net present value of the scheme liabilities. The assets of the scheme have been calculated below at open market value as at the year end and the liabilities have been calculated using the following actuarial assumptions.

	31 December 2023		31 December 2022		31 December 2021
	% per annum		% per annum		% per annum
Rate of discount	4.80		5.05		1.80
