The major risks which have been identified mainly relate lo a nel loss either al the annual meeting of the Society or at any of ils educational meetings. The most robust form of defence for this has been lo seek sponsorship by appropriate industry and this indeed is reflected in the accounts for the Society. Financial security has been considered such that all cheques need lo be signed by two signatories. The￿ is a limit of £1500 on the Society credit card for the Secretary General, £1500 for the Treasurer, £5,000 for the Executive Director and only the Executive Director currently holds a card. Expenditure for Board of Directors meetings and official travel has been capped al É750 for Europeans and É1500 for the International Board of Directors, there is allowance for a maximum of 2500 for travel over 3500 nautical miles. Our contract with our journal owner is being renegotiated as the journal costs are significantly lower being an online only journal since December 2020. This has enabled us to increase our membership, provide a Ihree-lier membership fee stnjcture for lower income countries and this in turn has strengthened our membership base.

The most robust form of defence for this has been lo seek sponsorship by appropriate industry and this indeed is reflected in the accounts for the Society. Financial security has been considered such that all cheques need lo be signed by two signatories. Online transactions are checked by Trustee Servet Bolukbas. There is a limit of £1500 on the Society credit card for the Secretary General, £1500 for the TreasLJrer, £5000 for the Executive Director and only the Executive Director currently holds a card. Expenditure for Board of Directors meetings and official travel has been capped al É750 for Europeans and É2000 for the International Board of Directors. Our contract with our journal publisher has been renegotiated lo make our major expense O"ournal printing and dislribulionl subslanlially less per capita. This has enabled us lo increase our membership, provide a three tier membership fee structure for lower income countries and this in turn has strengthened our membership base. The contract with the official Joumal hasn't been signed yet. The Society will continue lo provide high quality scientific education, training and credentialing of thoracic surgeons. The Board of Directors will review the situation periodically to plan any adjustment that may become necessary and will seek advice accordingly.

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 Charity's ability to continue as a going con￿r￿ for a period of al least twelve months from when the original financial statements were authorised for issue.

In preparing the financial statements, the Iruslees are responsible for assessing the Charity's ability to continue as a going cOn￿M, disclosing, as applicable, matters related to going concern and using the going con￿rn basis of accounting unless the trustees ef(her intend to liquidate the Charity or to ￿ase operations, or have no realistic alternative but lo do so. Our responslbllltles for the audlt of the flnanclal statements Our objectives are to obtain reasonable assurance about whether the financial statements as a whole are free from material misstatement, whether due lo fraud or error, and lo issue an aLJditor's report that includes our opinion. Reasonable assurance is a high level of assurance, bul is not a guarantee that an audit conducted in accordance with ISAS IUKI will always detect a material misslalement when it exists. Misslatemenls can arise from fraud or error and are considered material if, indThiidually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these financial stalemenls. 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 exlenl lo which our procedures are capable of detecting irregularities, including fraud is detailed below. As part of our audit planning we obtained an understanding of the legal and regulatory framework that is applicable to the charity and the sector in which il operates. The key laws and regulations we identrfied were Charities Act, regulations in relation lo data protection IGDPR}, and health and safely. We also considered those laws and regulations that have a direct impact on the preparation of the financial statements, primarily the Companies Act 2006, relevant tax and pensions laws. We discussed with management how compliance with these laws and regulations is monitored and discussed policies and procedures in place. We also identified the individuals who have responsibility for ensuring that the charity complies with laws and regulations and deals with reporting any issues if they arise. As part of our planning procedures, we assessed the risk of any non-compliance with laws and regulations on the charity's ability lo continue operating and the risk of material misstatement to the accounts. Based on this understanding we designed our audit procedures to idenlrfy non-compliance with such laws and regulations. Our procedures involved the following.. Enquiries of management and those charged with governance regarding their knowledge of any non-compliance with laws and regulations that could affect the financial slatemenls; Reviewing legal and professional costs lo identify any possible non Complian￿ or legal costs in respect of non compliance., Reviewing Trustees meeting minutes., Reviewing any health and safety incidents that have been reported under the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 20131"RIDDOR"I during the period.

We evaluated the risk of fraud through management override including that arising from management incentives. The key risks we identified were management bias in accounting judgements and estimates. In resFX)nse lo the identified risk, as part of our audit work we.. Confirmed on a sample basis that expenditure was properly authorised and made in accordan with the terms of the relevant fund., Used data analytics lo test journal entries throughout the year, for appropriateness- Reviewed estimates and judgements made in the accounts for any indication of bias and challenged assumptions used by management in making estimates. Because of the inherent limitations of an audit, there is a risk that we will not delect all irregularities, including those leading to a material misstatement in the financial statements. This risk increases the further removed non-compliance with laws and regulations is from the events and transactions reflected in the financial statements as we are less likely lo become aware of instances of non-compliance. The risk of not detecting a material misstalemenl due to fraud is higher than the risk of not detecting one resulting from error, as fraud may involve deliberate concealment, collusion, omission or misrepresenlalion. A further description of our responsibilities for the audit of the financial statements is located on the Financial Reporting Council's website al.. www.frc.org.uklauditorsresponsibilities. This description forms part of our auditor's report. Use of our Report This report is made solely lo the Charity's members, as a body, in 8ccordance with Chapter 3 of Part 16 of the Companies Act 2006.
