The Directors present their Group Strategic Report for Sonatest NDE Limited (the Group) for the year ended 31 December 2024.

The Group’s core focus remains to deliver simplicity, capability and reliability to its customers. This permeates the types of products and services that the company develops and the manner in which the Group delivers these products and services to its customers globally.

The directors formally review the risks and uncertainties facing the Group annually and continually monitor key risks and adopt mitigating strategies to ensure business security and continued progression.

Economic and market conditions: the group trades globally so we are able to quickly pivot our efforts to markets with the most favourable conditions. However escalating global geo-political tensions create a negative impact to the global economy which is harder to mitigate and is causing our cost base to rise. We are monitoring the situation closely.

Regulatory and legal risks: the nature of our product and services means it is not heavily regulated, though the Group does comply with all applicable regulation and legislation. However as a UK based company there is a risk that worsening geo-political tensions could close some markets to us.

Cybersecurity threats: the underlying risk from attempted hacking of our data is escalating. To mitigate this the Group has invested in modern Information Technology, moved most of our key activities to the cloud, we continually educate our users with on-line training and review and amend our internal controls as and when a new threat is identified.

Supply chain disruptions: following the semiconductor shortages of 2021-22 which created significant delays in supply for many industries not just ours, the Group has improved its demand forecasting and this has enabled more confidence to increase the size and duration of blanket orders with key supplies.

Competition and Technology: the NDT market is very competitive, but the development of new products is a significant barrier to entry. The Group continues to invest heavily in new products to maintain our competitive advantage.

The directors are confident that the Group is well placed to face the challenges ahead.

As reported in the Groups Profit & Loss account, Group Revenue has fallen from £13.1m to £11.9m (-10%) and the decrease is attributed to very difficult trading conditions in China and the USA, both of which were anticipated to be growing regions, but the unanticipated US tariff policy has had an impact. Gross profit is relatively stable at 50.8% vs 51.6% in the prior year. Administrative Expenses continue to increase from £5.3m to £5.6m but this is as a result of wage inflation and increased headcount rather than any external cost pressures. The reduction in Profit After Tax from £1.3m to £0.5m is a result of reduced revenues.

Management use a range of performance measures to monitor and manage the business. The principal financial measures are set out below:

The directors present their annual report and financial statements for the year ended 31 December 2025.

The principal activity of the company and group continued to be that of the design and manufacture of electronic instruments and transducers for the non-destructive testing of material using ultrasonic techniques.

The results for the year are set out on page 8.

Ordinary dividends were paid amounting to £600,000. The directors do not recommend payment of a further dividend.

The directors who held office during the year and up to the date of signature of the financial statements were as follows:

The Group continues to focus on research and development. Sonatest has a long history of product innovation and market firsts, which continues today with the Group's latest range of advanced NDT testing equipment.

The Group continues to invest in the development of new products and services with enhanced features to allow us to expand into new markets within NDT.

The auditor, Buckle Barton Limited, is deemed to be reappointed under section 487(2) of the Companies Act 2006.

The directors are responsible for preparing the annual report and the financial statements in accordance with applicable law and regulations.

United Kingdom company law requires the directors to prepare financial statements for each financial year. Under that law, the directors have elected to prepare the group and parent company financial statements in accordance with United Kingdom Generally Accepted Accounting Practice (United Kingdom Accounting Standards and applicable law). Under company law, the directors must not approve the financial statements unless they are satisfied that they give a true and fair view of the state of affairs of the group and parent company, and of the profit or loss of the group for that period.

In preparing these financial statements, the directors are required to:

• select suitable accounting policies and then apply them consistently;

• make judgements and accounting estimates that are reasonable and prudent;

• state whether applicable United Kingdom Accounting Standards have been followed, subject to any material departures disclosed and explained in the financial statements; and

• prepare the financial statements on the going concern basis unless it is inappropriate to presume that the group and parent company will continue in business.

The directors are responsible for keeping adequate accounting records that are sufficient to show and explain the group’s and parent company’s transactions and disclose with reasonable accuracy at any time the financial position of the group and parent company, and enable them to ensure that the financial statements comply with the Companies Act 2006. They are also responsible for safeguarding the assets of the group and parent company, and hence for taking reasonable steps for the prevention and detection of fraud and other irregularities.

So far as each person who was a director at the date of approving this report is aware, there is no relevant audit information of which the auditor of the company is unaware. Additionally, the directors individually have taken all the necessary steps that they ought to have taken as directors in order to make themselves aware of all relevant audit information and to establish that the auditor of the company is aware of that information.

We have audited the financial statements of Sonatest NDE Limited (the 'parent company') and its subsidiaries (the 'group') for the year ended 31 December 2025 which comprise the group profit and loss account, the group statement of comprehensive income, the group balance sheet, the company balance sheet, the group statement of changes in equity, the company statement of changes in equity, the group statement of cash flows and notes to the financial statements, including 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 the parent company's affairs as at 31 December 2025 and of the group's profit 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 Companies Act 2006.

Basis for opinion

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 and parent company 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 directors' 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 and parent company'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 directors 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 contained within the annual report. 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. 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 course of 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 this gives rise to a material misstatement in the financial statements themselves. 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.

Opinions on other matters prescribed by the Companies Act 2006

In our opinion, based on the work undertaken in the course of our audit:

• The information given in the strategic report and the directors' report for the financial year for which the financial statements are prepared is consistent with the financial statements; and

• The strategic report and the directors' report have been prepared in accordance with applicable legal requirements.

In the light of the knowledge and understanding of the group and the parent company and their environment obtained in the course of the audit, we have not identified material misstatements in the strategic report or the directors' report.

We have nothing to report in respect of the following matters in relation to which the Companies Act 2006 requires us to report to you if, in our opinion:

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

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

• certain disclosures of directors' remuneration specified by law are not made; or

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

As explained more fully in the directors' responsibilities statement, the directors 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 directors 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 directors are responsible for assessing the group's and parent company'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 directors either intend to liquidate the group or parent company or to cease operations, or have no realistic alternative but to do so.

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.

- We obtained an understanding of laws and regulations that affect the company, focusing on those that had a direct effect on the financial statements or that had a fundamental effect on its operations.  Key laws and regulations that we identified included the UK Companies Act, tax legislation and occupational health and employment legislation.

- We enquired of the directors for evidence of non compliance with relevant laws and regulations.  We also reviewed controls the directors have in place to ensure compliance.

- We gained an understanding of the controls that the directors have in place to prevent and detect fraud.  We enquired of the directors about any instances of fraud that had taken place during the accounting period.

- The risk of fraud and non-compliance with laws and regulations and fraud was discussed within the audit team and tests were planned and performed to address these risks.

- We reviewed financial statements disclosures and tested to supporting documentation to assess compliance with relevant laws and regulations discussed above.

- We enquired of the directors about actual and potential litigation and claims.

- We performed analytical procedures to identify any unusual or unexpected relationships that might indicate risks of material misstatement due to fraud.

-  In addressing the risk of fraud due to management override of internal controls we tested the appropriateness of journal entries and assessed whether the judgements made in making accounting estimates were indicative of a potential bias.

Due to the inherent limitations of an audit, there is an unavoidable risk that we may not have detected some material misstatements in the financial statements, even though we have properly planned and performed our audit in accordance with auditing standards.  For example, as with any audit, there remained a higher risk of non detection of irregularities, as these may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal controls.  We are not responsible for preventing fraud or non compliance with laws and regulations and cannot be expected to detect all fraud and non compliance with laws and regulations.

A further description of our responsibilities is available on the Financial Reporting Council’s website at: https://www.frc.org.uk/auditorsresponsibilities. This description forms part of our auditor's report.

Sonatest NDE Limited (“the company”) is a private limited company incorporated in England and Wales. The registered office is Dickens Road, Old Wolverton, Milton Keynes, MK12 5QQ.

The group consists of Sonatest NDE Limited and all of its subsidiaries.

These financial statements have been prepared in accordance with FRS 102 “The Financial Reporting Standard applicable in the UK and Republic of Ireland” (“FRS 102”) and the requirements of the Companies Act 2006.

The financial statements are prepared in sterling, which is the functional currency of the company. Monetary amounts in these financial statements are rounded to the nearest £'000.

The financial statements have been prepared under the historical cost convention. The principal accounting policies adopted are set out below.

In the parent company financial statements, the cost of a business combination is the fair value at the acquisition date of the assets given, equity instruments issued and liabilities incurred or assumed, plus costs directly attributable to the business combination. The excess of the cost of a business combination over the fair value of the identifiable assets, liabilities and contingent liabilities acquired is recognised as goodwill. The cost of the combination includes the estimated amount of contingent consideration that is probable and can be measured reliably, and is adjusted for changes in contingent consideration after the acquisition date. Provisional fair values recognised for business combinations in previous periods are adjusted retrospectively for final fair values determined in the 12 months following the acquisition date. Investments in subsidiaries, joint ventures and associates are accounted for at cost less impairment.

Deferred tax is recognised on differences between the value of assets (other than goodwill) and liabilities recognised in a business combination accounted for using the purchase method and the amounts that can be deducted or assessed for tax, considering the manner in which the carrying amount of the asset or liability is expected to be recovered or settled. The deferred tax recognised is adjusted against goodwill or negative goodwill.

The consolidated group financial statements consist of the financial statements of the parent company Sonatest NDE Limited together with all entities controlled by the parent company (its subsidiaries) and the group’s share of its interests in joint ventures and associates.

All financial statements are made up to 31 December 2025. Where necessary, adjustments are made to the financial statements of subsidiaries to bring the accounting policies used into line with those used by other members of the group.

All intra-group transactions, balances and unrealised gains on transactions between group companies are eliminated on consolidation. Unrealised losses are also eliminated unless the transaction provides evidence of an impairment of the asset transferred.

Subsidiaries are consolidated in the group’s financial statements from the date that control commences until the date that control ceases.

At the time of approving the financial statements, the directors have a reasonable expectation that the group and parent company have adequate resources to continue in operational existence for the foreseeable future. Thus the directors continue to adopt the going concern basis of accounting in preparing the financial statements.

Revenue comprises sales of goods or services provided to customers net of value added tax and other sales taxes, less an appropriate deduction for actual and expected returns and discounts. Revenue is recognised when performance obligations are satisfied and the control of goods or services is transferred to the buyer. Where the performance obligation is satisfied over time, revenue is recognised in accordance with its progress towards complete satisfaction of that performance obligation.

When cash inflows are deferred and represent a financing arrangement, the promised consideration is adjusted for the effects of the time value of money, which is recognised as interest income.

Revenue from the sale of goods is recognised when the significant risks and rewards of ownership of the goods have passed to the buyer (usually on dispatch of the goods), the amount of revenue can be measured reliably, it is probable that the economic benefits associated with the transaction will flow to the entity and the costs incurred or to be incurred in respect of the transaction can be measured reliably.

Research expenditure is written off against profits in the year in which it is incurred. Identifiable development expenditure is capitalised to the extent that the technical, commercial and financial feasibility can be demonstrated.

Tangible fixed assets are initially measured at cost and subsequently measured at cost or valuation, net of depreciation and any impairment losses.

Depreciation is recognised so as to write off the cost or valuation of assets less their residual values over their useful lives on the following bases:

The gain or loss arising on the disposal of an asset is determined as the difference between the sale proceeds and the carrying value of the asset, and is recognised in the profit and loss account.

Equity investments are measured at fair value through profit or loss, except for those equity investments that are not publicly traded and whose fair value cannot otherwise be measured reliably, which are recognised at cost less impairment until a reliable measure of fair value becomes available.

In the parent company financial statements, investments in subsidiaries, associates and jointly controlled entities are initially measured at cost and subsequently measured at cost less any accumulated impairment losses.

A subsidiary is an entity controlled by the group. Control is the power to govern the financial and operating policies of the entity so as to obtain benefits from its activities.

At each reporting period end date, the group reviews the carrying amounts of its tangible assets to determine whether there is any indication that those assets have suffered an impairment loss. If any such indication exists, the recoverable amount of the asset is estimated in order to determine the extent of the impairment loss (if any). Where it is not possible to estimate the recoverable amount of an individual asset, the company estimates the recoverable amount of the cash-generating unit to which the asset belongs. The carrying amount of the investments accounted for using the equity method is tested for impairment as a single asset. Any goodwill included in the carrying amount of the investment is not tested separately for impairment.

Recoverable amount is the higher of fair value less costs to sell and value in use. In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset for which the estimates of future cash flows have not been adjusted. If the recoverable amount of an asset (or cash-generating unit) is estimated to be less than its carrying amount, the carrying amount of the asset (or cash-generating unit) is reduced to its recoverable amount. An impairment loss is recognised immediately in profit or loss, unless the relevant asset is carried at a revalued amount, in which case the impairment loss is treated as a revaluation decrease.

Recognised impairment losses are reversed if, and only if, the reasons for the impairment loss have ceased to apply. Where an impairment loss subsequently reverses, the carrying amount of the asset (or cash-generating unit) is increased to the revised estimate of its recoverable amount, but so that the increased carrying amount does not exceed the carrying amount that would have been determined had no impairment loss been recognised for the asset (or cash-generating unit) in prior years. A reversal of an impairment loss is recognised immediately in profit or loss, unless the relevant asset is carried at a revalued amount, in which case the reversal of the impairment loss is treated as a revaluation increase.

Stocks are stated at the lower of cost and estimated selling price less costs to complete and sell. Cost comprises direct materials and, where applicable, direct labour costs and those overheads that have been incurred in bringing the stocks to their present location and condition.

Stocks held for distribution at no or nominal consideration are measured at the lower of cost and replacement cost, adjusted where applicable for any loss of service potential.

At each reporting date, an assessment is made for impairment. Any excess of the carrying amount of stocks over its estimated selling price less costs to complete and sell is recognised as an impairment loss in profit or loss. Reversals of impairment losses are also recognised in profit or loss.

Cash and cash equivalents are basic financial assets and include cash in hand, deposits held at call with banks, other short-term liquid investments with original maturities of three months or less, and bank overdrafts. Bank overdrafts are shown within borrowings in current liabilities.

The group has elected to apply the provisions of Section 11 ‘Basic Financial Instruments’ and Section 12 ‘Other Financial Instruments Issues’ of FRS 102 to all of its financial instruments.

Financial instruments are recognised in the group's balance sheet when the group becomes party to the contractual provisions of the instrument.

Financial assets and liabilities are offset and the net amounts presented in the financial statements when there is a legally enforceable right to set off the recognised amounts and there is an intention to settle on a net basis or to realise the asset and settle the liability simultaneously.

Basic financial assets, which include debtors and cash and bank balances, are initially measured at transaction price including transaction costs and are subsequently carried at amortised cost using the effective interest method unless the arrangement constitutes a financing transaction, where the transaction is measured at the present value of the future receipts discounted at a market rate of interest. Financial assets classified as receivable within one year are not amortised.

Other financial assets, including investments in equity instruments which are not subsidiaries, associates or joint ventures, are initially measured at fair value, which is normally the transaction price. Such assets are subsequently carried at fair value and the changes in fair value are recognised in profit or loss, except that investments in equity instruments that are not publicly traded and whose fair values cannot be measured reliably are measured at cost less impairment.

Financial assets, other than those held at fair value through profit and loss, are assessed for indicators of impairment at each reporting end date.

Financial assets are impaired where there is objective evidence that, as a result of one or more events that occurred after the initial recognition of the financial asset, the estimated future cash flows have been affected. If an asset is impaired, the impairment loss is the difference between the carrying amount and the present value of the estimated cash flows discounted at the asset’s original effective interest rate. The impairment loss is recognised in profit or loss.

If there is a decrease in the impairment loss arising from an event occurring after the impairment was recognised, the impairment is reversed. The reversal is such that the current carrying amount does not exceed what the carrying amount would have been, had the impairment not previously been recognised. The impairment reversal is recognised in profit or loss.

Financial assets are derecognised only when the contractual rights to the cash flows from the asset expire or are settled, or when the group transfers the financial asset and substantially all the risks and rewards of ownership to another entity, or if some significant risks and rewards of ownership are retained but control of the asset has transferred to another party that is able to sell the asset in its entirety to an unrelated third party.

Financial liabilities and equity instruments are classified according to the substance of the contractual arrangements entered into. An equity instrument is any contract that evidences a residual interest in the assets of the group after deducting all of its liabilities.

Basic financial liabilities, including creditors, bank loans, loans from fellow group companies and preference shares that are classified as debt, are initially recognised at transaction price unless the arrangement constitutes a financing transaction, where the debt instrument is measured at the present value of the future payments discounted at a market rate of interest. Financial liabilities classified as payable within one year are not amortised.

Debt instruments are subsequently carried at amortised cost, using the effective interest rate method.

Trade creditors are obligations to pay for goods or services that have been acquired in the ordinary course of business from suppliers. Amounts payable are classified as current liabilities if payment is due within one year or less. If not, they are presented as non-current liabilities. Trade creditors are recognised initially at transaction price and subsequently measured at amortised cost using the effective interest method.

Derivatives, including interest rate swaps and forward foreign exchange contracts, are not basic financial instruments. Derivatives are initially recognised at fair value on the date a derivative contract is entered into and are subsequently re-measured at their fair value. Changes in the fair value of derivatives are recognised in profit or loss in finance costs or finance income as appropriate, unless hedge accounting is applied and the hedge is a cash flow hedge.

Debt instruments that do not meet the conditions in FRS 102 paragraph 11.9 are subsequently measured at fair value through profit or loss. Debt instruments may be designated as being measured at fair value through profit or loss to eliminate or reduce an accounting mismatch or if the instruments are measured and their performance evaluated on a fair value basis in accordance with a documented risk management or investment strategy.

Financial liabilities are derecognised when the group's contractual obligations expire or are discharged or cancelled.

Equity instruments issued by the group are recorded at the proceeds received, net of transaction costs. Dividends payable on equity instruments are recognised as liabilities once they are no longer at the discretion of the group.

The tax expense represents the sum of the tax currently payable and deferred tax.

The tax currently payable is based on taxable profit for the year. Taxable profit differs from net profit as reported in the profit and loss account because it excludes items of income or expense that are taxable or deductible in other years and it further excludes items that are never taxable or deductible. The group’s liability for current tax is calculated using tax rates that have been enacted or substantively enacted by the reporting end date.

Deferred tax liabilities are generally recognised for all timing differences and deferred tax assets are recognised to the extent that it is probable that they will be recovered against the reversal of deferred tax liabilities or other future taxable profits. Such assets and liabilities are not recognised if the timing difference arises from goodwill or from the initial recognition of other assets and liabilities in a transaction that affects neither the tax profit nor the accounting profit.

Provisions are recognised when the group has a legal or constructive present obligation as a result of a past event, it is probable that the group will be required to settle that obligation and a reliable estimate can be made of the amount of the obligation.

The amount recognised as a provision is the best estimate of the consideration required to settle the present obligation at the reporting end date, taking into account the risks and uncertainties surrounding the obligation. Where the effect of the time value of money is material, the amount expected to be required to settle the obligation is recognised at present value. When a provision is measured at present value, the unwinding of the discount is recognised as a finance cost in profit or loss in the period in which it arises.

The costs of short-term employee benefits are recognised as a liability and an expense, unless those costs are required to be recognised as part of the cost of stock or fixed assets.

The cost of any unused holiday entitlement is recognised in the period in which the employee’s services are received.

Termination benefits are recognised immediately as an expense when the company is demonstrably committed to terminate the employment of an employee or to provide termination benefits.

Payments to defined contribution retirement benefit schemes are charged as an expense as they fall due.

Rentals payable under operating leases, including any lease incentives received, are charged to profit or loss on a straight line basis over the term of the relevant lease except where another more systematic basis is more representative of the time pattern in which economic benefits from the leased asset are consumed.

Transactions in currencies other than pounds sterling are recorded at the rates of exchange prevailing at the dates of the transactions. At each reporting end date, monetary assets and liabilities that are denominated in foreign currencies are retranslated at the rates prevailing on the reporting end date. Gains and losses arising on translation in the period are included in profit or loss.

In the application of the group’s accounting policies, the directors are required to make judgements, estimates and assumptions about the carrying amount of assets and liabilities that are not readily apparent from other sources. The estimates and associated assumptions are based on historical experience and other factors that are considered to be relevant. Actual results may differ from these estimates.

The estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognised in the period in which the estimate is revised where the revision affects only that period, or in the period of the revision and future periods where the revision affects both current and future periods.

The estimates and assumptions which have a significant risk of causing a material adjustment to the carrying amount of assets and liabilities are as follows.

The company provides for stock deemed to be obsolete or which has become written down in value. The provision is based in the ratio of historical information of sales and usages compared to quantities of stock held.

The Group provides for costs of future repairs under warranty. The provision is based on the ratio of historical warranty costs incurred to current sales volumes sold still under warranty.

The following are the major deferred tax liabilities and assets recognised by the group and company:

A defined contribution pension scheme is operated for all qualifying employees. The assets of the scheme are held separately from those of the group in an independently administered fund.

Section 22 - presentation and disclosure of 'A' Ordinary shares

In accordance with Section 22 the company's 'A' Ordinary shares are termed compound instruments and comprise both debt and equity components. The debt component of the shares are classed as financial liabilities and disclosed within creditors. The equity component is treated as 'other equity reserves' and forms part of shareholders' funds.

The holders of the non-equity 'A' Ordinary shares are entitled to:

(i) a fixed cumulative preferential dividend of 33.3p per share per annum;

(ii) a participating dividend varying with profits;and

(iii) convert at any time the whole of the 'A' Ordinary share into ordinary shares on the basis of one ordinary share for each 'A' ordinary share held.

On a winding up the 'A' Ordinary shareholders are entitled to the repayment of the subscription price in priority to Ordinary shareholders. Thereafter, subject to a payment on each Ordinary share equal to the amount of capital paid on each 'A' Ordinary share, any surplus is payable as though all shares were of the same class.

The share premium account represents cumulative premium charged on the issue of share capital.

The Capital redemption reserve represents cumulative share capital repurchased by the Group for cancellation.

Profit & loss account

The Profit and loss account represents the cumulative profits and losses of the Group, less any dividends paid.

At the reporting end date the group had outstanding commitments for future minimum lease payments under non-cancellable operating leases, which fall due as follows:
