Underwriting performance
YOA:
The 2022 YOA has closed with a profit of £93.5m after all standard personal expenses, equivalent to a profit on stamp capacity of 26.7%.  The claims experience for
the YOA has been good, with Hurricane Ian and Winter Storm Elliott the largest losses to impact the year.  Investment return for the YOA was also better than plan,
boosted by increased interest rates.
The 2023 YOA is forecast at the 24 months to make a mid-point profit of £131.4m. The YOA has benefited from a low incidence of major natural catastrophe losses to
date. A forecast is not currently required for the 2024 YOA.

Calendar year:
The profit for the 2024 calendar year is £124.1m (2023: £134.7m), which is better than plan. Premium growth has been strong, driven primarily by new A&H, marine
and crisis management classes and despite an active US wind season, underwriting returns are healthy.  The premium growth and favourable claims environment have
led to strong inwards underwriting cashflow in the year while investment returns in the year have been boosted by elevated interest rates.  The calendar year result
together with key performance indicators is shown below:

The claims ratio is the ratio of claims incurred net of reinsurance to earned premiums net of reinsurance. The expense ratio is the ratio of operating expenses and
acquisition costs (excluding foreign exchange movements) to earned premiums net of reinsurance. The claims ratio reflects the underwriting issues noted above, and
the expense ratio is broadly in line with plan. The combined ratio including all foreign exchange movements is 85.0% (2023: 80.9%).

Managing agent’s report  
Financial position
The main components of the statement of financial position are technical provisions and investments and cash.
Technical provisions include a provision for outstanding claims of £636.2m (2023: £519.8m) and a provision for unearned premiums of £351.2m (2023: £284.6m). The
reinsurers’ share of technical provisions is £85.1m (2023: £76.3m) in respect of unearned premiums and £27.1m (2023: £15.8m) for outstanding claims. The provision
for outstanding claims is based on evaluations of reported claims and estimates for losses incurred but not reported (“IBNR”). As claims may not be settled for a number
of years after they are incurred, the setting of provisions involves a degree of judgement as to the ultimate exposure to losses. Investments and cash total £755.4m
(2023: £647.2m) the majority of which are actively managed by third party investment managers.
Auditors and Annual general meeting
As permitted under the Syndicate Meeting (Amendment No.1) Byelaw it is not proposed to hold a Syndicate Annual General Meeting. The member of the Syndicate
appointed PricewaterhouseCoopers LLP as auditors for the financial year ending 31 December 2024.
Disclosure of information to auditors
The directors of ASML who held office at the date of approval of this report confirm that, so far as they are each aware, there is no relevant audit information of which
the auditors of the Syndicate are unaware; and each director has taken all the steps that they ought to have taken as a director to make themselves aware of any
relevant audit information and to establish that the auditors of the Syndicate are aware of that information.
Directors 
The directors of ASML served from 1 January 2024 to the date of this report, unless stated otherwise.  Shareholdings in the ultimate parent company of ASML, Ark
Insurance Holdings Limited (“AIHL”) are stated as at 31 December 2024.

Going concern
The directors of ASML have reviewed the business plan, liquidity and operational resilience of the company, including the risks associated with the ongoing conflict in
Ukraine and the recent wildfires in California. They have concluded that there are no material uncertainties that could cast significant doubt over the Syndicate’s
ability to continue as a going concern for at least a year from the date of approval of the Syndicate annual accounts. Management's assessment of going concern is
set out in note 1 on page 17.

Statement of managing agent’s responsibilities 
The directors of the managing agent are responsible for preparing the Syndicate annual accounts in accordance with applicable law and regulations.
The Insurance Accounts Directive  (Lloyds’s  Syndicate and Aggregate Accounts) Regulations 2008 requires the directors of  the managing  agent  to  prepare  their
Syndicate’s annual accounts for each financial year. Under that law they have elected to prepare the annual accounts in accordance with UK Accounting Standards
and applicable law (UK Generally Accepted Accounting Practice), including FRS 102 The Financial Reporting Standard applicable in the UK and Republic of Ireland.
Under Insurance Accounts Directive (Lloyds’s Syndicate and Aggregate Accounts) Regulations 2008 the directors of the managing agent must not approve the annual
accounts unless they are satisfied that they give a true and fair view of the state of affairs of the Syndicate and of the profit or loss of the Syndicate for that period. In
preparing these annual accounts, the directors of the managing agent are required to:
  select suitable accounting policies and then apply them consistently;
  make judgements and estimates that are reasonable and prudent;
  state whether applicable UK Accounting Standards have been followed, subject to any material departures disclosed and explained in the annual accounts;
  assess the syndicate’s ability to continue as a going concern, disclosing, as applicable, matters related to going concern; and
  use the going concern basis of accounting unless they either intend to cease trading, or have no realistic alternative but to do so.  
The directors of the managing agent are responsible for the preparation and review of the iXBRL tagging that has been applied to the Syndicate Accounts in accordance
with the instructions issued by Lloyd’s, including designing, implementing, and maintaining systems, processes and internal controls to result in tagging that is free from
material non-compliance with the instructions issued by Lloyd’s, whether due to fraud or error. 
The directors of the managing agent are responsible for keeping adequate accounting records that are sufficient to show and explain the Syndicate’s transactions and
disclose with reasonable accuracy at any time the financial position of the Syndicate and enable them to ensure that the Syndicate annual accounts comply with the
Insurance Accounts Directive (Lloyds’s Syndicate and Aggregate Accounts) Regulations 2008. They are responsible for such internal control as they determine is
necessary to enable the preparation of Syndicate annual accounts that are free from material misstatement, whether due to fraud or error, and have general responsibility
for taking such steps as are reasonably open to them to safeguard the assets of the Syndicate and to prevent and detect fraud and other irregularities.
The directors of the managing agent are responsible for the maintenance and integrity of the Syndicate and financial information included on the Syndicate’s website.
Legislation in the UK governing the preparation and dissemination of Syndicate annual accounts may differ from legislation in other jurisdictions.

Independent auditors’ report to the member of Syndicate 4020 
Opinion
In our opinion, 4020’s syndicate annual accounts: 
  give a true and fair view of the state of the syndicate’s affairs as at 31 December 2024 and of its profit and cash flows for the year then ended;
  have  been  properly prepared  in  accordance  with  United  Kingdom  Generally  Accepted  Accounting Practice  (United  Kingdom  Accounting  Standards, 
including FRS 102 “The Financial Reporting Standard applicable in the UK and Republic of Ireland”, and applicable law); and
  have been prepared in accordance with the requirements of The Insurance Accounts Directive (Lloyd’s Syndicate and Aggregate Accounts) Regulations
2008 and the requirements within the Lloyd’s Syndicate Accounts Instructions version 2.0 as modified by the Frequently Asked Questions issued by Lloyd’s 
version 1.1 (“the Lloyd’s Syndicate Instructions”). 
We have audited the syndicate annual accounts included within the Report and Financial Statements (the “Annual Report”), which comprise: the statement of financial 
position as at 31 December 2024; the income statement, the statement of comprehensive income, the statement of cash flows and the statement of changes in members
balances for the year then ended; and the notes to the syndicate annual accounts which include a description of the significant accounting policies.
Basis for opinion 
We conducted our audit in accordance with International Standards on Auditing (UK) (“ISAs (UK)”), The Insurance Accounts Directive (Lloyd’s Syndicate and Aggregate
Accounts) Regulations 2008, the Lloyd’s Syndicate Instructions and other applicable law. Our responsibilities under ISAs (UK) are further described in the Auditors’
responsibilities for the audit of the syndicate annual accounts section of our report. We believe that the audit evidence we have obtained is sufficient and appropriate to
provide a basis for our opinion.
Independence
We remained independent of the syndicate in accordance with the ethical requirements that are relevant to our audit of the syndicate annual accounts in the UK, which
includes the FRC’s Ethical Standard, as applicable to other entities of public interest, and we have fulfilled our other ethical responsibilities in accordance with these
requirements.
To the best of our knowledge and belief, we declare that non-audit services prohibited by the FRC’s Ethical Standard were not provided. 
Conclusions relating to going concern
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 syndicate’s ability to continue as a going concern for a period of at least twelve months from when the syndicate annual accounts are authorised
for issue.
In auditing the syndicate annual accounts, we have concluded that the Managing Agent’s use of the going concern basis of accounting in the preparation of the syndicate
annual accounts is appropriate.
However, because not all future events or conditions can be predicted, this conclusion is not a guarantee as to the syndicate's ability to continue as a going concern.
Our responsibilities and the responsibilities of the Managing Agent with respect to going concern are described in the relevant sections of this report.
Reporting on other information
The other information comprises all of the information in the Annual Report other than the syndicate annual accounts and our auditors’ report thereon. The Managing
Agent is responsible for the other information. Our opinion on the syndicate annual accounts does not cover the other information and, accordingly, we do not express
an audit opinion or, except to the extent otherwise explicitly stated in this report, any form of assurance thereon.
In connection with our audit of the syndicate annual accounts, our responsibility is to read the other information and, in doing so, consider whether the other information
is materially inconsistent with the syndicate annual accounts or our knowledge obtained in the audit, or otherwise appears to be materially misstated. If we identify an
apparent material inconsistency or material misstatement, we are required to perform procedures to conclude whether there is a material misstatement of the syndicate
annual accounts 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 based on these responsibilities.
With respect to the Managing Agent’s Report (the “Managing Agent’s Report”), we also considered whether the disclosures required by The  Insurance Accounts
Directive (Lloyd’s Syndicate and Aggregate Accounts) Regulations 2008 have been included.

Independent auditors’ report to the member of Syndicate 4020
Based on our work undertaken in the course of the audit, The Insurance Accounts Directive (Lloyd’s Syndicate and Aggregate Accounts) Regulations 2008 requires us
also to report certain opinions and matters as described below.
Managing Agent’s Report 
In our opinion, based on the work undertaken in the course of the audit, the information given in the Managing Agent’s Report for the year ended 31 December 2024 is
consistent with the syndicate annual accounts and has been prepared in accordance with applicable legal requirements.
In light of the knowledge and understanding of the syndicate and its environment obtained in the course of the audit, we did not identify any material misstatements in
the Managing Agent’s Report. 
Responsibilities for the syndicate annual accounts and the audit
Responsibilities of the Managing Agent for the syndicate annual accounts
As explained more fully in the Statement of Managing Agent’s Responsibilities, the Managing Agent is responsible for the preparation of the syndicate annual accounts
in accordance with the applicable framework and for being satisfied that they give a true and fair view. The Managing Agent is also responsible for such internal control
as they determine is necessary to enable the preparation of syndicate annual accounts that are free from material misstatement, whether due to fraud or error.
In preparing the syndicate annual accounts, the Managing Agent is responsible for assessing the syndicate’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 it is intended for the syndicate to cease operations, or it has no
realistic alternative but to do so.
Auditors’ responsibilities for the audit of the syndicate annual accounts 
Our objectives are to obtain reasonable assurance about whether the syndicate annual accounts as a whole are free from material misstatement, whether due to fraud
or error, and to issue an auditors’ 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 syndicate annual accounts.
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 syndicate and industry, we identified that the principal risks of non-compliance with laws and regulations related to breaches of
regulatory principles, such as those governed by the Prudential Regulation Authority and the Financial Conduct Authority, and those regulations set by the Council of
Lloyd’s, and we considered the extent to which non-compliance might have a material effect on the syndicate annual accounts. We also considered those laws and
regulations that have a  direct impact on the syndicate annual accounts such as The Insurance Accounts Directive (Lloyd’s Syndicate and Aggregate Accounts)
Regulations 2008 and the Lloyd’s Syndicate Instructions . We evaluated management’s incentives and opportunities for fraudulent manipulation of the syndicate annual
accounts (including the risk of override of controls), and determined that the principal risks were related to the risk of fraud in revenue recognition, journal entries, and
the potential for management bias in significant accounting estimates, particularly in relation to incurred but not reported claims provisions included in technical provisions
and the estimation of gross written premiums. Audit. Audit procedures performed by the engagement team included:
  Discussions  with  senior  management  involved  in  the  Risk  and  Compliance  functions,  including  consideration  of  known  or  suspected  instances  of
noncompliance with laws and regulation and fraud;
  Assessment of any matters reported in the fraud suspicion log and the compliance issues and breach log and the results of management’s investigation of 
such matters;
  Reading key correspondence with Lloyd’s, the Prudential Regulation Authority and the Financial Conduct Authority in relation to compliance with laws and
regulations;  
  Reviewing relevant meeting minutes including those of the Board and Audit and Risk Assurance Committee;
  Testing journal entries identified in accordance with our fraud risk assessment.

Independent auditors’ report to the member of Syndicate 4020
  Testing and challenging where appropriate the assumptions and judgements made by management in their significant accounting estimates, particularly in
relation to incurred but not reported provisions included in technical provision and the estimation of gross written premiums; and
  Designing audit procedures to incorporate unpredictability around the nature, timing or extent of our testing.
There are inherent limitations in the audit procedures described above. We are less likely to become aware of instances of non-compliance with laws and regulations
that are not closely related to events and transactions reflected in the syndicate annual accounts. Also, the risk of not detecting a material misstatement due to fraud is
higher than the risk of not detecting one resulting from error, as fraud may involve deliberate concealment by, for example, forgery or intentional misrepresentations, or
through collusion.
A further description of our responsibilities for the audit of the syndicate annual accounts is located on the FRC’s website at: www.frc.org.uk/auditorsresponsibilities. 
This description forms part of our auditors’ report. 
Use of this report
This report, including the opinions, has been prepared for and only for the syndicate’s member in accordance with part 2 of The Insurance Accounts Directive (Lloyd’s
Syndicate and Aggregate Accounts) Regulations 2008 and for no other purpose. We do not, in giving these opinions, accept or assume responsibility for any other
purpose or to any other person to whom this report is shown or into whose hands it may come save where expressly agreed by our prior consent in writing.
Other required reporting
Under The Insurance Accounts Directive (Lloyd’s Syndicate and Aggregate Accounts) Regulations 2008 we are required to report to you if, in our opinion:
  we have not obtained all the information and explanations we require for our audit; or
  adequate accounting records have not been kept by the Managing Agent in respect of the syndicate; or
  certain disclosures of Managing Agent remuneration specified by law are not made; or
  the syndicate annual accounts are not in agreement with the accounting records.
We have no exceptions to report arising from this responsibility.
Other matter
We draw attention to the fact that this report may be included within a document to which iXBRL tagging has been applied. This auditors’ report provides no assurance
over whether the iXBRL tagging has been applied in accordance with section 2 of the Lloyd’s Syndicate Instructions version 2.0.

Notes to the financial statements 
1.   Statement of accounting policies
The financial statements have been prepared in accordance with the Insurance Accounts Directive (Lloyd’s Syndicate and Aggregate Accounts) Regulations 2008 and
Financial Reporting Standard 102 The Financial Reporting Standard applicable in the UK and Republic of Ireland (“FRS 102”) as issued in August 2015, and Financial 
Reporting Standard 103 Insurance Contracts (“FRS 103”) as issued in March 2015, as well as the Lloyd’s Syndicate Accounts Instructions Version 2.0 as modified by
the Frequently Asked Questions Version 1.1 issued by Lloyd’s. 
Basis of preparation
The financial statements are prepared using the historical cost convention except that financial investments and derivative financial instruments are stated at their fair
value. All amounts presented are stated in Sterling, unless stated otherwise.
The financial statements have been prepared on a going concern basis. The directors of ASML have performed an assessment of the Syndicate’s ability to continue as
a going concern, including the impact of the ongoing Ukraine conflict and the recent wildfires in California.  A going concern assessment has been undertaken, taking
into consideration availability of capital, liquidity and stress testing. The Syndicate is expected to remain a key underwriting platform for the Ark group. Ark Corporate
Member Limited (“ACML”) has already provided capital to support the 2025 YOA.  On the basis of this and the improvement in performance as a result of rate increases,
ACML is also expected to have the ability and intention to form a 2026 underwriting year. The directors of ASML have therefore concluded that there are no material
uncertainties that could have cast significant doubt over the ability of the company to continue as a going concern for at least a year from the date of approval of the
financial statements.
During 2024, Lloyds introduced changes to the syndicate accounts process to rationalise and standardise financial reporting across the market. As a result, certain
comparative information has been restated to ensure consistency with current year presentation and compliance with the  Lloyd’s Syndicate Accounts Instructions.
These changes comprise of reclassification and aggregation changes and are presented in further detail with note 22.
Use of judgements and estimates 
In preparing these accounts, the directors of ASML have made judgements, estimates and assumptions that affect the application of the Syndicate’s accounting policies
and the reported amounts of assets, liabilities, income and expenses.  Actual results may differ from these estimates.  Estimates and underlying assumptions are
reviewed on an ongoing basis. Revisions to estimates are recognised prospectively.  The measurement of  written premium inwards, and  the provision for claims 
outstanding are the two most critical estimates and both involve judgements and assumptions about the future that have a significant effect on the amounts recognised
in the financial statements.  Refer to the Premiums written and earned section and note 13 (Technical provisions) for further details on these estimates.
Insurance contracts
Insurance contracts (including inwards reinsurance contracts) are defined as those containing significant insurance risk. Insurance risk is considered significant if, and
only if, an insured event could cause Ark to pay significant additional benefits in any scenario, excluding scenarios that lack commercial substance.  Such contracts
remain insurance contracts until all rights and obligations are extinguished or expire.
Premiums written and earned
Gross premium written is initially based on estimated premium income (“EPI”) of each contract. EPI is based on information provided by the brokers, policyholders, 
coverholders, past underwriting experience, and the contractual terms of the policy. Uncertainty arises because EPI could be different to the signed premium ultimately
received. This risk is mitigated by detailed reviews of EPI and signed premium and regular reviews that coverholder income is coming through as expected.
Gross premium written includes an estimation for reinstatement premium which is determined based on incurred losses held in the technical provisions. Reviews of the
reinstatement premiums held is carried out on a regular basis as part of the reserve review process.
Ark Syndicate Management Limited
Syndicate 4020

Notes to the financial statements
1.  Statement of accounting policies (continued)
Written premiums are recognised as earned according to the risk profile of the policy.  Unearned premiums represent the proportion of premiums written in the year
that relate to unexpired terms of policies in force at the statement of financial position date. The provision is calculated on a policy by policy basis.
Reinsurance premiums ceded
Outwards reinsurance premiums are accounted for in the same accounting year as the premiums for the direct or inwards business being reinsured.  
Claims provisions and related recoveries
The provision for claims comprises amounts set aside for claims notified and IBNR.  Claims incurred comprise claims and claims handling expenses paid in the year
and the movement in provision for outstanding claims and future claims handling expenses. Recoverable amounts arising out of subrogation and salvage together with
reinsurance recoveries are deducted from the cost of gross claims.   
Outstanding claims consist of amounts set aside for notified claims and a provision for IBNR claims.  The amount included in respect of IBNR is arrived at by considering
the actuarially calculated provision, using techniques that generally involve statistical techniques of estimation applied by ASML’s actuaries and reviewed by external
consulting actuaries, as well as the opinion of the class underwriters and executive management.  The actuarial techniques generally involve projecting from past
experience of the development of claims over time to form a view of the likely ultimate claims to be experienced for more recent underwriting having regard to variations
in the business accepted and the underlying terms and conditions.  Large claims are generally assessed individually, being calculated on a case by case basis or
projected separately to allow for the possible distortive effects of the developments of these claims on the balance of the data. The provision for claims also includes
amounts in respect of internal and external claims handling costs.
The reinsurers’ share of provisions for claims is based on calculated amounts of outstanding claims and projections for IBNR, net of estimated irrecoverable amounts, 
having regard to the reinsurance programme in place for the class of business, the claims experience for the year and the current security rating of the reinsurance
companies involved. The Syndicate uses a number of statistical techniques to assist in making these estimates.
Accordingly the two most critical assumptions as regards claims provisions are that the past is a reasonable predictor of the likely level of claims development and that
the rating and other models used for current business are fair reflections of the likely level of ultimate claims to be incurred.  Ultimate liability will vary as a result of
subsequent information and events and this may result in significant adjustments to the amounts provided. Adjustments to the amount of claims provisions established
in prior years are reflected in the financial statements for the year in which the adjustments are made.  The methods used, and the estimates made, are reviewed
regularly.
Acquisition costs
Acquisition costs, comprising brokerage and taxes and duties levied on them are deferred to the extent that they are attributable to premiums unearned at the statement
of financial position date.
Foreign currency translation
a) Functional and presentation currency
Items included in the financial statements are measured using  the US dollar, the currency of the primary economic environment in which the  Syndicate operates
(functional currency). The financial statements are presented in Sterling, being the presentation currency of the Syndicate.  Differences arising from the translation
from the functional to presentation currency are presented in the statement of other comprehensive income.
b) Transactions and balances
Foreign currency transactions are translated into the functional currency using average exchange rates applicable to the period in which the transactions take place
and where the company considers these to be a reasonable approximation of the transaction rate.   Foreign exchange gains and losses resulting from the settlement
of such transactions and from translation at the period end of monetary assets and liabilities denominated in foreign currencies are recognised in the statement of profit
or loss.  Non-monetary items recorded at historical cost in foreign currencies are translated using the exchange rate on the date of the initial transaction.  For the
purposes of foreign currency translation, unearned premiums and deferred acquisition costs are treated as if they are monetary items.

Notes to the financial statements
1.  Statement of accounting policies (continued)
Investments
Investments are recognised in the statement of financial position at such time as the Syndicate becomes a party to the contractual provisions of the  investment.
Purchases and sales of investments are recognised on the trade date, which is the date the  Syndicate commits to purchase or sell the asset.  An  investment is
derecognised when the contractual rights to receive cash flows from the investments expire, or where the investments have been transferred, together with substantially
all the risks and rewards of ownership. Financial liabilities are derecognised if the obligations specified in the contract expire, are discharged or cancelled.
On acquisition of an investment, the Syndicate is required to classify the asset into one of the following categories: investments at fair value through the statement of
profit or loss, loans and receivables, assets held to maturity and assets available for sale.  The Syndicate has classified its investments as investments at fair value
through profit or loss because they are managed and their performance is evaluated on a fair value basis. Information about these investments is provided internally
on a fair value basis to management, and the investment strategy is to invest and evaluate their performance with reference to their fair values.
Fair value is the price at which an orderly transaction to sell an asset or to transfer a liability would take place between market participants at the measurement date.
When available, the fair value of an instrument is measured using quoted prices in an active market for that instrument. A market is regarded as active if quoted prices
are readily and regularly available and represent actual and regularly occurring market transactions on an arm’s length basis. If a market for a financial instrument is
not active, the fair value is established using a valuation technique.
Valuation techniques include using recent orderly transactions between market participants (if available), reference to the current fair value of other instruments that
are substantially the same, discounted cash flow analyses and option pricing models. The chosen valuation technique makes maximum use of market inputs, relies as
little as possible on specific estimates, incorporates all factors that market participants would consider in setting a price, and is consistent with accepted economic
methodologies for pricing financial instruments.  Inputs to valuation techniques reasonably represent market expectations and measures of the risk-return factors
inherent in the financial instrument.
Where possible, valuation techniques are calibrated and tested for validity using prices from observable current market transactions in the same instrument or based
on other available observable market data.
The best evidence of the fair value of a financial instrument at initial recognition is the transaction price, i.e. the fair value of the consideration given or received, unless
the fair value of that instrument is evidenced by comparison with other observable current market transactions in the same instrument (i.e. without modification or
repackaging) or based on a valuation technique whose variables include only data from observable markets. When transaction price provides the best evidence of fair
value at initial recognition, the financial instrument is initially measured at the transaction price and any difference between this price and the value initially obtained
from a valuation model is subsequently recognised in profit or loss depending on the individual facts and circumstances of the transaction but not later than when the
valuation is supported wholly by observable market data or the transaction is closed out.
Upon initial recognition, attributable transaction costs relating to financial instruments at fair value through profit or loss are recognised in the statement of profit or loss
when incurred. Investments at fair value through profit or loss are continually measured at fair value, and changes therein are recognised in the statement of profit or
loss. Net changes in the fair value of investments at fair value through profit or loss exclude interest and dividend income, as these items are accounted for separately
as set out below.
Debtors and creditors arising out of insurance operations
Debtors and creditors arising out of insurance operations are recognised when due.  These include amounts due to and from agents, brokers and insurance contract
holders.  Debtors arising out of insurance operations are classified as loans and receivables as they are non-derivative investments with fixed or determinable payments
that are not quoted on an active market. Debtors arising out of insurance operations are measured at amortised cost less any impairment losses. Insurance payables
are stated at amortised cost.
Other receivables
Other receivables are carried at amortised cost less any impairment losses.

Notes to the financial statements
1.  Statement of accounting policies (continued)
Investment return
Investment return consists of dividends, interest, realised and unrealised gains and losses and foreign exchange gains and losses on investments at fair value through
the statement of profit or loss. Dividends on equity securities are recorded as revenue on the ex-dividend date. Interest is recognised separately on an amortised cost
basis using the effective interest rate method for investments at fair value through the statement of profit or loss.  The realised gains or losses on disposal of an
investment are the difference between the proceeds and the original cost of the investment. Unrealised investment gains and losses represent the difference between
the carrying value at the reporting date, and the carrying value at the previous period end or purchase value during the period. 
Creditors arising out of insurance operations
Creditors arising out of insurance operations are stated at amortised cost determined on the effective interest rate method.
Cash and cash equivalents
Cash and cash equivalents consist of cash at bank and in hand, deposits held at call with banks and other short-term highly liquid investments with maturities of three
months or less from the date of acquisition. They are classified as loans and receivables and carried at amortised cost less any impairment losses. 
2.  Management of risk
Approach to risk management
Ark’s core business relies on the assumption of internal and external risk within the appetites and tolerances established by the Board. Primarily Ark’s business is the 
assumption of Insurance Risk and Market Risk, with the additional categories of Credit Risk, Liquidity Risk, Operational Risk and Group Risk. Managing these risks in
a manner that is consistent with the strategy, appetites and tolerances established by the Board requires that Ark has in place a systematic, objective, and robust set
of governance arrangements and processes for identifying and quantifying the risks to which it is exposed. This enables Ark to determine appropriate strategies and
approaches for prevention and mitigation.
The effectiveness with which Ark manages risk is a key determinant of the level of capital resources required to run the business and its ability to achieve its strategic
objectives including, in relation to capital efficiency and the production of acceptable levels of return.
Insurance risk
This is the risk arising from the uncertainties in timing, frequency and severity of insured losses, relative to the expectations made at the time of business planning or
underwriting. Ark’s business is based on the seeking and assumption of insurance risk. The Syndicate writes a balanced and diversified book of business through a
team of experienced underwriters with the objective of charging appropriate premiums to cover claims and operational costs whilst optimising the expected return on
equity.  Target returns are assessed each year, taking into account the insurance market outlook and realistic expectations of return on equity. Insurance risk comprises
the following elements:
a) Exposure management risk
This is the risk of exposure to an event, or a series of events, which causes a potential financial loss that exceeds expectations.  The nature of Ark’s business and
underwriting portfolio includes the assumption of a high degree of catastrophe, non-catastrophe and accumulative exposure to different events. This is managed through
the purchase of reinsurance and diversification of business lines and geographical areas to balance exposures, with the aim of reducing the risk that one event, or a
series of events, will cause unacceptable loss to the business. Ark’s catastrophe and non-natural catastrophe modelling processes incorporate Ark-specific disaster
scenarios, aggregate caps and cross-class modelling which reflect the diversity of the portfolio.
b) Underwriting quality risk
This is the risk of inappropriate underwriting or the inadequate pricing of risks which can lead to unprofitable business or inefficient line utilisation and risk selection.
The management of underwriting quality can be difficult in a competitive market where underwriters are often under pressure to meet premium and pricing targets. Ark
operates an underwriting controls framework which includes individual underwriting authorities, continual quality monitoring and peer review of risks. The framework
aims to ensure a high quality of underwriting through monitoring of pricing and rate change, contract certainty and agreement of appropriate terms and conditions.

1.  Management of risk (continued)
c) Delegated underwriting quality risk
This is the risk of exposure to inappropriate risks through the delegation of underwriting authorities to third parties or the delegation of authority to inappropriate third
parties. The nature of delegated underwriting naturally increases the risk of underwriting, through the ability of third parties being able to bind the Syndicate to risks
without detailed review of the risk involved.  This risk is mitigated through the application of strict guidelines, managed by a dedicated team within the Compliance
department.  This team reviews coverholder and third party authority (“TPA”) approvals pre-bind and monitors a programme of audits to ensure compliance with 
regulations and guidelines. 
D) Claims management risk
This is the risk that claims made are not managed in an appropriate manner, leading to material adverse results through an increase in claims, payments or exposure
to legal issues. The management of claims is conducted in accordance with claims procedures, which are, in turn, in line with the Lloyd’s Minimum Standards. This
includes the management of claims workflows and response times, reviews of major claims to ensure accurate estimates, regular reserving reviews and management
of complaints.  These processes are enhanced through communication with underwriting teams to understand the policy or portfolio and with the Compliance department
to manage coverholders and TPAs.
e) Reserving risk
This is the risk that the estimated claims reserves differ materially from the ultimate cost of the claim or event. Reserving risk is a significant category in the Internal
Model and has the potential to significantly impact profitability. The potential impact is controlled through the use of a mix of actuarial models and methods, industry
data and underwriter experience to produce reliable estimates that are based on up to date information, and consistently applied over time and across classes of
business.  Reserves for losses arising from the Ukraine conflict are included in the normal process as a major loss.  This does not pose a potential threat to the business
or risk of going concern.  These estimates are subject to an external review each year.
f) Reinsurance purchasing
This is the risk of purchasing insufficient or inappropriate reinsurance, or the exhaustion of reinsurance, leading to excessive or unexpected losses.  The process of
reinsurance purchasing forms a major part of Ark’s business planning process and includes the use of the Internal Model as a tool for decision making. Reinsurance
is purchased for a mixture of risk and event losses across the majority of classes, in a mixture of excess of loss and proportional cover, dependent on the scale and
characteristics of the class or treaty concerned. Ark also employs controls and monitoring around the use of insurers, credit ratings and concentration risk.
g) Underwriting management
This is the risk that returns from the policies written are different from expectations or are not in line with the business plan. Examples include a failure to reduce or exit
from unprofitable business or a failure of underwriters to follow the business plan which sets out the parameters, classes, limitations and profitability expectation of
underwriting teams for the forthcoming year. Communication of the business plan to the underwriting teams is therefore imperative. The performance of each class
and the syndicate portfolio as a whole is reviewed against the business plan on a regular basis by the Board and various committees using information available from
the management information portal. Various controls are in place to ensure constant vigilance including underwriting authorities, monitoring of risk codes, geographical
aggregates and data quality.

1.  Management of risk (continued)
Credit risk
Credit risk arises when counterparties fail to meet their obligations in full as they fall due.  The key areas where credit risk can arise include reinsurers, brokers,
coverholders and investment counterparties.
The probability of reinsurer default is modelled by the Actuarial team as part of the Internal Model. Ark seeks to reduce this risk by avoiding over-reliance on specific
reinsurers through the application of concentration limits and thresholds.  This is monitored by the Security Advisory Committee (SAC).  Prior to the transaction of
business, broker and coverholder default is mitigated through the application of due diligence on new and existing counterparties, and a rolling audit schedule post-
bind.  Overdue premium is also monitored by class, broker and age of debt.  The investment portfolio is managed in line with asset allocation guidelines which are
monitored by type, counterparty, quality and duration. Ark outsources the management of a significant proportion of its investment portfolio to managers who monitor
and report on performance and adherence to guidelines on a regular basis.

2.  Management of risk (continued)
Debtors arising out of insurance operations and other debtors balances have not been impaired, based on all evidence available, and no impairment provision has been
recognised in respect of these assets. Inwards premium receivables are credit controlled by third-party managers. Ark monitors third party coverholders’ performance 
and their financial processes through the coverholder management team. A provision for doubtful debts is included within reinsurers' share of technical provisions of
£2.3m (2023: £1.9m).  
Financial assets that are past due or impaired
The Syndicate has debtors arising from direct insurance and reinsurance operations that are past due but not impaired at the reporting date.  An analysis of the carrying

Market risk
This is the risk that the value of assets and liabilities changes as a result of market movements e.g. foreign exchange rates, interest rates and market prices.
a) Foreign exchange risk
The functional currency of the Syndicate is the US dollar and the presentation currency in which the Syndicate reports its results is Sterling. Therefore the Syndicate
is exposed to fluctuations in exchange rates for non-dollar denominated transactions.  The Syndicate operates in five main currencies: US dollars, Sterling, Canadian
dollars, Australian dollars and Euros.  The underwriting capital is matched by currency to the principal underlying currencies of its written premiums. This helps to
mitigate the risk that the capital required to underwrite business is materially affected by any future movements in exchange rates.

b) Interest rate risk
Some of the financial instruments, including certain investments at fair value, cash and cash equivalents and borrowings, are exposed to movements in market interest
rates. Interest rate risk is managed by primarily investing in short-duration investments and cash and cash equivalents. The duration of assets is monitored on a regular
basis. The duration of assets exposed to movements in market interest rates is 1.29 (2023: 1.19). Changes in interest rates, with all other variables constant, would
result in changes in the capital value of debt securities and borrowings as well as subsequent interest receipts and payments.

Liquidity risk
Liquidity risk arises where cash may not be available to pay obligations when they fall due without incurring unreasonable penalties or expense costs.  The risk is
minimised by holding sufficient liquid assets to enable large and unexpected payments, predominately claims, to be made in all but the most extreme scenarios.  Ark’s
Catastrophe Event Response Plan provides information to quantify liquidity implications of losses, reinsurance recoveries, cashflows and trust funds in the event of a
catastrophe or large loss. The process is stress tested using historic scenarios to determine the behaviour of the portfolio following an event or series of events.

Operational risk
Operational risk is the risk of loss resulting from inadequate or failed internal processes or systems. Risks are identified within the risk register and are modelled via
operational scenarios.  Ark aims to minimise its exposure to operational risk by monitoring controls and management information in the form of key indicators that
indicate changes to the risk profile.
Ark outsources a number of key functions, such as investment management, inwards premium credit control and human resources.  This introduces the risk that the
Syndicate may be exposed to liability or may fail to achieve its objectives due to inappropriately arranged, or a failure of, outsource arrangements.  This risk is mitigated
through pre-contract due diligence and performance review throughout the contract life cycle. 
Ark recognises that the success of a business depends on the ability to retain the services of existing key staff and to attract and retain additional people in the future,
both in underwriting and support functions.  This risk is managed through the provision of sufficient education and development, support for qualifications and competitive
remuneration packages.
Ark is also impacted by the risk of information technology system failure or disruption. This is mitigated through a control framework which includes network security,
data, hardware and applications and is complimented by detailed planning around back-ups, contingency and disaster recovery, all of which are monitored and tested 
on a regular basis.
Regulatory risk
Regulatory risk is the risk of censure following a breach of regulatory or legal requirements, or a failure to respond to deadlines or information requests from regulators
in a satisfactory and timely manner.
Ark is regulated, overseen or required to report to the Prudential Regulation Authority (“PRA”), the Financial Conduct Authority (“FCA”), Lloyd’s and other overseas
regulators. Each body requires adherence to specific requirements and guidelines. In order to mitigate this, Ark seeks to conform to the regulations as they apply to
each functional area. Much of this is operated through training and awareness to promote correct behaviour at source, as opposed to corrective action at a later stage.
The overall risk is managed by the Compliance department which seeks to ensure that deadlines are met and changes in regulation are communicated in a timely
manner.
Ark has put in place processes and controls to identify and manage the conduct risk associated with the business it underwrites. Ark will continue to lead high product
risk business where risks are consistent with the probability targets taking into account the additional requirements for oversight and monitoring conduct risk.

2.  Management of risk (continued)
Capital management risk
Capital is primarily required to support underwriting at Lloyd’s. Lloyd’s applies capital requirements at member level and centrally to ensure that Lloyd’s complies with
Solvency II, and beyond that to meet its own financial strength, licence and ratings objectives.
In order to meet Lloyd’s requirements, each syndicate is required to calculate its Solvency Capital Requirement (“SCR”) for the prospective underwriting year. This
amount must be sufficient to cover a 1 in 200 year loss, reflecting uncertainty in the ultimate run-off of underwriting liabilities (SCR ‘to ultimate’). The syndicate must
also calculate its SCR at the same confidence level but reflecting uncertainty over a one year time horizon (one year SCR) for Lloyd’s to use in meeting Solvency II
requirements. The SCRs of each syndicate are subject to review by Lloyd’s and approval by the Lloyd’s Capital and Planning Group. 
Each member of a syndicate is liable for its own share of underwriting liabilities on the syndicate(s) on which it is participating. Each member’s SCR is determined by
the sum of the member’s share of the syndicate SCR ‘to ultimate’. Where a member participates on more than one syndicate, a credit for diversification is provided to
reflect the spread of risk, but consistent with determining an SCR which reflects the capital requirement to cover a 1 in 200 year loss ‘to ultimate’ for that member. Over
and above this, an uplift is applied by Lloyd’s to the member’s capital requirement, known as the Economic Capital Assessment (“ECA”).

The fair values of investments are based on prices provided by investment managers who obtain market data from numerous independent pricing services.  The pricing
services used by the investment manager obtain actual transaction prices for securities that have quoted prices in active markets. For those securities which are not
actively traded, the pricing services use common market valuation pricing models. Observable inputs used in common market valuation pricing models include, but are
not limited to, broker quotes, credit ratings, interest rates and yield curves, prepayment speeds, default rates and other such inputs which are available from market
sources.
Level 1 includes fair values measured using quoted prices (unadjusted) in active markets for identical instruments. Level 2 includes fair values measured using directly
or indirectly observable inputs or other similar valuation techniques for which all significant inputs are based on market observable data. Level 3 includes fair values
measured using valuation techniques for which significant inputs are not based on market observable data.
The fair value of these assets is based on the prices obtained from both investment managers and investment custodians.

Assumptions and processes
a) The reserving process
Ark uses a quarterly process to set its reserves. Several actuarial and statistical methods are used to estimate the ultimate premium and claims costs, with the most
appropriate method selected depending on the nature of each class of business. In addition, the underwriting teams review the development of the incurred loss ratio
over time, work with the claims team to set reserve estimates for identified claims and utilise their detailed understanding of both risks underwritten and the nature of
the claims to establish an alternative estimate of ultimate claims cost, which is compared  to  the  actuarially established  figures.  The Reserving Committee then 
determines the reserves held for accounting purposes.  An annual independent actuarial review is undertaken to ensure that the reserves established are not lower
than an independently established best estimate.

Notes to the financial statements 
13.  Technical provisions (continued)
Chain-ladder techniques are applied to premiums, paid claims and incurred claims (i.e. paid claims plus case estimates). The basic technique involves the analysis of 
historical claims development factors and the selection of estimated development factors based on historical patterns. The selected development factors are then
applied to cumulative claims data for each underwriting year that is not yet fully developed to produce an estimated ultimate claims cost for each underwriting year.  The
Bornhuetter-Ferguson method uses a combination of a benchmark / market-based estimate and an estimate based on claims experience.  The former is based on a
measure of exposure such as premiums; the latter is based on the paid or incurred claims observed to date. The two estimates are combined using a formula that gives
more weight to the experience-based estimate as time passes.  
The choice of selected results for each underwriting year of each class of business depends on an assessment of the technique that has been most appropriate to
observed historical developments. In certain instances, this has meant that different techniques or combinations of  techniques have been selected for individual
underwriting years or groups of underwriting years within the same class of business. As such, there are many assumptions used to estimate general insurance liabilities.
Triangulations of the paid / outstanding claim ratios are also reviewed as a way of monitoring any changes in the strength of the outstanding claim estimates between
underwriting years so that adjustments can be made to mitigate any subsequent over/(under) reserving.
Where significant large losses impact an underwriting year, the development is usually very different from the attritional losses. In these situations, the large loss total
is extracted from the remainder of the data and analysed separately by the respective claims managers using exposure analysis of the policies in force in the areas
affected.  Further assumptions are required to convert gross of reinsurance estimates of ultimate claims cost to a net of reinsurance level and to establish reserves for
unallocated claims handling expenses and reinsurance bad debt.
b) Major assumptions
The main assumption underlying these techniques is that the Syndicate’s past claims development experience (with appropriate adjustments for known changes) can
be used to project future claims development and hence ultimate claims costs. As such these methods extrapolate the development of premiums, paid and incurred
losses, average costs per claim and claim numbers for each underwriting year based on the observed development of earlier years.  Throughout, judgement is used to 
assess the extent to which past trends may not apply in the future; for example, to reflect changes in external or market factors such as economic conditions, public
attitudes to claiming, levels of claims inflation, premium rate changes, judicial decisions and legislation, as well as internal factors such as portfolio mix, policy conditions
and claims handling procedures.
The loss development tables below provide information about historical claims development by the identified operating segments. The tables are by underwriting year
which in our view provides the most transparent reserving basis. The top part of the table illustrates how the estimate of the claims ratio for each underwriting year has
changed at successive year ends.  The bottom half of the table reconciles the gross and net claims to the amount appearing in the statement of financial position.  While
the information in the table provides a historical perspective on the adequacy of the claims liabilities established in previous years, users of these financial statements
are cautioned against extrapolating past redundancies or deficiencies on current claims liabilities. The Syndicate believes that the estimate of total claims liabilities
selected is adequate. However, due to inherent uncertainties in the reserving process, it cannot be assured that such balances will ultimately prove to be adequate.

21.  Post balance sheet events
The California wildfires in January 2025 represent a significant industry loss event. Industry estimates are still preliminary and range widely. The Syndicate will have
exposure to this event primarily through the property line of business. At this time, the directors of ASML do not expect the wildfire losses will cause full year 2025
actual catastrophe losses to diverge materially from those planned for.
