Dechra Pharmaceuticals PLC is a public limited company, which is listed on the London Stock Exchange and incorporated and domiciled in the United Kingdom. The address of its registered office is 24 Cheshire Avenue, Cheshire Business Park, Lostock Gralam, Northwich, England. The principal accounting policies applied in the preparation of these consolidated financial statements are set out below, these have been applied consistently in all years presented with the exception of the adoption of new accounting standards as outlined below.

(a) Statement of Compliance

These consolidated financial statements have been prepared and approved by the Directors in accordance with International Financial Reporting Standards (IFRSs) and IFRS Interpretations Committee (IFRS IC) as adopted by the European Union, and the Companies Act 2006 applicable to companies reporting under IFRS. The Company has elected to prepare its Parent Company financial statements in accordance with FRS 101 and they are separately presented in the Company Statement of Financial Position, Company Statement of Changes in Shareholders' Equity and Notes to the Company Financial Statements.

(b) Basis of Preparation

The Group's business activities together with the factors likely to affect its future development, performance and position are set out in the Strategic Report. The Directors have a reasonable expectation that the Company and Group have adequate resources to continue in operational existence for the foreseeable future. Accordingly, they continue to adopt the going concern basis of accounting in preparing the annual financial statements. Refer to the Corporate Governance Report for details.

The consolidated financial statements are presented in Sterling, rounded to the nearest million. They are prepared on a going concern basis and under the historical cost convention, except where IFRSs require an alternative treatment. The principal variations relate to derivative financial instruments, cash settled share-based transactions, contingent consideration and assets and liabilities acquired through business combinations that are stated at fair value.

The preparation of consolidated financial statements in conformity with IFRSs requires the use of accounting estimates and for management to exercise its judgement in the process of applying the Group's accounting policies. These judgements and estimates are based on historical experience and management's best knowledge of the amounts, events or actions under review and the actual results may ultimately differ from these estimates. Areas involving a high degree of judgement or complexity, or areas where assumptions and estimates are significant to the consolidated financial statements, are, where necessary, disclosed separately.

Prior Year Restatement

The comparative amounts for 30 June 2018 have been restated to provide for the statutory merger relief from share premium on shares issued by the company when acquiring shares in AST Farma and Le Vet in February 2018. During the measurement period the share premium amount has been reclassified to the merger reserve. As a consequence share premium has been reduced by £82.6 million and the merger reserve increased by £82.6 million. The impact on net assets is nil.

Critical Judgements in Applying the Group's Accounting Policies and Key Sources of Estimation Uncertainty

In the process of applying the Group's accounting policies, the Directors have made the following judgements and estimates that have the most significant effect on the amounts recognised in the financial statements. The key sources of estimation uncertainty which may cause a material adjustment to the carrying amount of assets and liabilities are also discussed below.

(i) Carrying value of Goodwill and Indefinite Life Intangible Assets

The Group determines whether goodwill and indefinite life assets are impaired at least on an annual basis or whenever there is an indication of impairment. This requires an estimation of the value in use of the cash generating units to which they are allocated. Estimating the value in use requires the Group to make an estimate of the expected future cash flows from the cash generating unit and also to choose a suitable discount rate in order to calculate the present value of those cash flows. The determination of an appropriate discount rate involves estimation, and is based on the advice of third party valuers. Further detail on the assumptions used in determining value in use calculations is provided in note 14.

(ii) Valuation of Assets & Liabilities acquired through Business Combinations

Judgement is required as part of the purchase price allocation of a business combination, specifically around the identification of acquired assets and liabilities, such as product rights, commercial relationships, pharmacological processes and brand intangibles. The identification is based on the Group's industry experience and the advice of third party valuers. As part of a business combination, fair values are attributed to the identifiable assets and liabilities of the acquired business. This requires a number of estimates to be made, including future cash flows of the acquired business and the determination of an appropriate discount rate. The Group will generally engage an independent valuer to advise on the determination of these fair values. Further details can be found in note 32.

(iii) Valuation of Licensing Agreements and associated Deferred Considerations

The recognition of intangible assets and associated deferred considerations in respect of licensing agreements are recorded initially at fair value. This is based on management's best estimate of the timing, likelihood and quantum of future cash flows discounted at an appropriate discount rate. The assumptions relating to future cash flows are based on management's industry expertise and assessment of project viability. The determination of an appropriate discount rate also involves estimation and is based on the advice of third party valuers. A range of discount rates between 2.4% and 12.5% have been determined as being appropriate as applicable for each specific deferred consideration liability. Further details can be found in note 33.

(iv) Uncertain Tax Positions

Provision is made for any uncertain tax positions that the Group may be exposed to at the statement of financial position date. Uncertain tax positions are considered on an individual basis. Where management considers it probable that an additional outflow will result from any given position, a provision is made. Such provisions are measured using management's best estimate and where appropriate, consideration of external advice.

At 30 June 2019 the Group held a current provision of £3.8 million (2018: £2.6 million) in respect of uncertain tax positions. The resolution of these tax matters may take many years.

(v) Non-underlying Items

The Group presents a number of non-GAAP measures. This is to allow investors to understand the underlying performance of the Group, excluding items associated with areas such as: amortisation of acquired intangibles; remeasurement and accounting for the passage of time in respect of contingent considerations; unwind of fair value adjustments to inventory arising from business combinations; non-recurring expenses relating to Brexit; expenses relating to acquisition and subsequent integration activities; rationalisation of the manufacturing organisation; loss on extinguishment of debt; and the revaluation of deferred tax balances following substantial tax legislation changes. Management utilise this measure to isolate the impact of exceptional, one-off or non-trading related items and consequently the classification of these items requires judgement. Further details can be found in note 5.

Adoption of New and Revised Standards

The following standards, amendments to standards or interpretations have been adopted for the first time from 1 July 2018. Please refer to note 36 for more detail on the impact of adoption on the financial statements.

• IFRS 15 'Revenue from contracts with customers' provides a single, principles-based approach to the recognition of revenue from all contracts with customers, reflecting the transfer of goods and services at a value that the Group expects to be entitled to receive.
• IFRS 9 'Financial Instruments' introduces changes to the classification, measurement and de-recognition of financial assets and financial liabilities, provides a new impairment model for financial assets based on expected losses and stipulates a new hedge accounting model.

New Standards and amendments to Standards or Interpretations

The following standards, amendments to standards or interpretations are mandatory for the first time from 1 July 2019;

• IFRS 16 'Leases'; is effective for accounting periods on or after 1 January 2019 and will replace existing accounting standards. The Standard provides a single lessee accounting model, requiring lessees to recognise assets and liabilities for all leases unless the lease term is 12 months or less or the underlying asset has a low value. The standard will affect primarily the accounting for the Group's operating leases. As at the reporting date, the Group has non-cancellable operating lease commitments of £16.4 million.
• The Group will adopt IFRS16 from 1 July 2019 using the modified retrospective approach with the right of use asset on transition equalling the lease liability. The cumulative effect of initially adopting IFRS16 will be recognised as an increase to assets and liabilities at 1 July 2019 with no restatement of comparative information. The Group intends to avail itself of the exemptions for short term leases and leases of low value items.
• Based on the information currently available the estimated impact of the adoption of IFRS 16 is:
  • the recognition of additional fixed assets and lease liabilities of approximately £14.0 million on the Consolidated Statement of Financial Position at 1 July 2019;
  • an increase in operating profit of £0.2 million due to the differential between the IAS 17 lease cost and the IFRS 16 depreciation cost;
  • a decrease in profit before tax of £0.2 million due to the differential between the IAS 17 lease cost and the IFRS 16 depreciation and interest cost.

There are no other new standards, amendments to existing standards or interpretations that are not yet effective that would be expected to have a material impact on the Group.

(c) Basis of Consolidation

Subsidiary Undertakings

Subsidiary undertakings are fully consolidated from the date on which control is transferred to the Group. They cease to be consolidated from the date that the Group no longer has control. All subsidiary undertakings have been consolidated. Inter-company transactions, balances and unrealised gains and losses on transactions between Group companies are eliminated on consolidation. Non-controlling interests represent the portion of shareholders' earnings and equity attributable to third party shareholders. The financial statements of all subsidiary undertakings are prepared to the same reporting date as the Company, with the exception of Genera Pharma d.o.o., Laboratorios Vencofarma do Brasil Ltda and Dechra-Brovel S.A. de C.V. (all of which prepare local financial statements to 31 December each year, in line with local tax authority regulations).

Associates

Associates are all entities over which the Group has significant influence but not control, generally accompanying a shareholding of between 20% and 50% of the voting rights. Investments in associates are accounted for using the equity method of accounting. Under the equity method, the investment is initially recognised at cost, and the carrying amount is increased or decreased to recognise the investor's share of the change in net assets of the investee after the date of acquisition. Intangible assets identified as part of the notional purchase price allocation are amortised over the useful life of each asset, with the Group's share recognised as a charge in the income statement.

The Group's share of post-acquisition profit or loss is recognised in the income statement, and its share of post-acquisition movements in other comprehensive income is recognised in other comprehensive income with a corresponding adjustment to the carrying amount of the investment. Distributions received from an associate reduce the carrying amount of the investment.

The Group determines at each reporting date whether there is any objective evidence that the investment in the associate is impaired. If this is the case, the Group calculates the amount of impairment as the difference between the recoverable amount of the associate and its carrying value and recognises the amount adjacent to share of profit/(loss) of associates in the income statement.

Gains and losses resulting from upstream and downstream transactions between the Group and its associate are recognised in the Group's financial statements only to the extent of unrelated investors' interests in the associates. Unrealised losses are eliminated unless the transaction provides evidence of an impairment of the asset transferred. Accounting policies of associates have been changed where necessary to ensure consistency with the policies adopted by the Group.

(d) Foreign Currency Translation

(i) Functional and Presentational Currency

The consolidated financial statements are presented in Sterling, which is the Group's presentational currency, and are rounded to the nearest hundred thousand, except where it is deemed relevant to disclose the amounts to the nearest million. Items included in the financial statements of each of the Group's entities are measured using the currency of the primary economic environment in which the entity operates (the functional currency).

(ii) Foreign Currency Translation

Foreign currency transactions are translated into the functional currency using the exchange rates prevailing at the dates of the transaction. Foreign exchange gains and losses resulting from the settlement of such transactions and from the translation of monetary assets and liabilities denominated in foreign currencies are recognised in the income statement, with the exception of differences on transactions that are subject to effective cash flow hedges, which are recognised in other comprehensive income.

(iii) Foreign Operations

The income and expenses are translated to Sterling at the average rate for the period being reported. The assets and liabilities of foreign operations are translated to Sterling at the closing rate at the reporting date. Foreign currency differences on all translations are recognised in other comprehensive income in the foreign currency translation reserve, a separate component of equity.

Goodwill and fair value adjustments arising on the acquisition of a foreign entity are treated as assets and liabilities of the foreign entity and translated at the closing rate. On disposal of a foreign entity, accumulated exchange differences previously recognised in other comprehensive income are recognised in the income statement in the same period in which the gain or loss on disposal is recognised.

(e) Accounting for Financial Assets and Liabilities, Derivative Financial Instruments and Hedging Activities

Financial Assets

At initial recognition, the Group measures a financial asset at its fair value plus, in the case of a financial asset not at fair value through profit or loss (FVPL), transaction costs that are directly attributable to the acquisition of the financial asset. Transaction costs of financial assets carried at FVPL are expensed in profit or loss.

Management determines the classification of its financial assets at initial recognition in accordance with IFRS 9, which defines 3 categories that debt instruments may be classified as, depending on the purpose for which the assets are held. These categories are;

• Amortised cost;
• Fair value through other comprehensive income (FVOCI);
• Fair value through the profit and loss (FVPL)

Amortised cost relates to assets that are held for collection of contractual cash flows. Where those cash flows represent solely payments of principal and interest, they are measured at amortised cost. Interest income from these financial assets is included in finance income using the effective interest rate method. Any gain or loss arising on derecognition is recognised directly in the income statement. All material financial assets of the Group are held at amortised cost.

Financial assets are derecognised when the rights to receive cash flows from the assets have expired or have been transferred and the Group has transferred substantially all risks and rewards of ownership. Gains and losses (both realised and unrealised) arising from changes in the value of financial assets held at fair value through the income statement are included in the income statement in the period in which they arise.

Derivative Financial Instruments

The Group uses derivative financial instruments to manage its exposure to interest rate risks. In accordance with its treasury policy, the Group does not hold or issue derivative financial instruments for speculative purposes. However, derivatives that do not qualify for hedge accounting are accounted for as trading instruments. Derivatives are initially recognised at fair value on the date a derivative contract is entered into and are remeasured to fair value at each reporting date.

Cash Flow Hedges

Changes in the fair value of derivative financial instruments designated as cash flow hedges are recognised in other comprehensive income to the extent that the hedge is effective. To the extent that the hedge is ineffective, changes in fair value are recognised immediately in the income statement. If the hedging instrument no longer meets the criteria for hedge accounting, expires or is sold, terminated or exercised, then hedge accounting is discontinued prospectively. The cumulative gain or loss previously recognised in other comprehensive income remains there until the forecast transaction occurs.

Net Investment Hedge

For hedges of net investments in foreign operations, where the hedge is effective movements are recognised in other comprehensive income. Ineffectiveness is recognised in the income statement. Gains and losses accumulated in equity are included in the income statement when the foreign operation is partially disposed of or sold.

Trade Receivables

Trade receivables are recorded at aggregate invoice value (including value added tax or other sales taxes) less loss allowances, which are calculated using the expected loss model. Where trade receivables contain a significant financing component, they are then carried at amortised cost using the effective interest rate method, less loss allowances. Other receivables are recorded at their transaction value.

The Group assesses, on a forward-looking basis, the expected credit losses associated with its trade and other receivables. The Group applies the simplified approach permitted by IFRS 9, which requires expected lifetime losses to be recognised from initial recognition of the receivables. Where there is a specific risk surrounding a receivable then a credit loss allowance of 100% is applied.

Trade and Other Payables

Trade and other payables are initially recognised at fair value and subsequently at amortised cost.

Borrowings and Borrowing Costs

Borrowings are recognised initially at fair value net of directly attributable transaction costs incurred. Borrowings are subsequently stated at amortised cost. Any difference between the proceeds (net of transaction costs) and the redemption value is recognised in the income statement over the period of the borrowings using the effective interest method. Borrowings are classified as current liabilities unless the Group has a right to defer settlement of the liability for at least 12 months after the reporting date.

Borrowing costs directly attributable to the acquisition, construction, or production of qualifying assets, which are assets that take a substantial period of time to get ready for their intended use or sale, are added to the cost of those assets, until such time as the assets are substantially ready for their intended use. All other borrowing costs are recognised in the income statement in the period in which they are incurred.

(f) Property, Plant and Equipment

Owned Assets

Items of property, plant and equipment are stated at cost less accumulated depreciation and impairment losses.

Leased Assets

Leases under the terms of which the Group assumes substantially all the risks and rewards of ownership are classified as finance leases. Assets acquired by finance leases are stated at an amount equal to the lower of their fair value and the present value of the minimum lease payments at inception of the lease, less accumulated depreciation and impairment losses.

Depreciation

Depreciation is charged to the income statement on a straight-line basis over the estimated useful life of each part of an item of property, plant and equipment. Land is not depreciated. Assets in the course of construction are not depreciated until the date the assets become available for use. The estimated useful lives are as follows:

The residual value, where significant, is reassessed annually.

(g) Intangible Assets

Goodwill

All business combinations are accounted for by applying the purchase method. Goodwill represents amounts arising on acquisition of subsidiaries, associates and joint ventures. In respect of business acquisitions that have occurred before 1 July 2004, goodwill represents the difference between the cost of the acquisition and the fair value of the separable assets, liabilities and contingent liabilities acquired.

Acquisitions after this date fall under the provisions of 'Revised IFRS 3 Business Combinations (2009)'. For these acquisitions, transaction costs, other than share and debt issue costs, are expensed as incurred and subsequent adjustments to the fair value of consideration payable are recognised in the income statement.

Contingent consideration is measured at fair value based on an estimate of the expected future payments.

Goodwill is stated at cost less any accumulated impairment losses. Goodwill is not amortised but is allocated to cash generating units and is tested annually for impairment.

Research and Development Costs

Expenditure on research activities, undertaken with the prospect of gaining new scientific or technical knowledge and understanding, is recognised in the income statement as an expense is incurred.

The Group is also engaged in development activity with a view to bringing new pharmaceutical products to market. Due to the strict regulatory process involved, there is inherent uncertainty as to the technical feasibility of development projects often until regulatory approval is achieved, with the possibility of failure even at a late stage. The Group considers that this uncertainty means that the criteria for capitalisation are not met unless it is highly probable that regulatory approval will be achieved and the project is commercially viable. Internally generated costs of development are capitalised, once the criteria are met, in the consolidated statement of financial position unless those costs cannot be measured reliably or it is not probable that future economic benefits will flow to the Group, in which case the relevant costs are expensed to the income statement as incurred.

Where development costs are capitalised, the expenditure includes the cost of materials, direct labour and an appropriate proportion of overheads. Capitalised development expenditure is stated at cost less accumulated amortisation and impairment losses.

Acquired Intangible Assets

Intangible assets recognised as a result of a business combination are stated at fair value at the date of acquisition less accumulated amortisation and impairment losses.

Other Intangible Assets

Other intangible assets that are acquired by the Group are stated at cost (including future milestone and royalty payments as applicable) less accumulated amortisation and impairment losses. Expenditure on internally generated goodwill and other intangibles is recognised in the income statement as an expense is incurred.

(h) Intangible Assets Subsequent Expenditure

Subsequent expenditure on capitalised intangible assets is capitalised only when it increases the future economic benefits embodied in the specific asset to which it relates or extends the asset life. All other expenditure is expensed as incurred.

Amortisation

Amortisation is charged to the income statement on a straight-line basis over the estimated useful lives of intangible assets unless such lives are indefinite or is otherwise stated below. Goodwill and intangible assets with an indefinite useful life are systematically tested for impairment at each consolidated statement of financial position date. Intangible assets are amortised from the date that they are available for use. Assets in the course of construction are not amortised until the date the assets become available for use.

The estimated useful lives are as follows:

•  software	5 to 7 years
•  capitalised development costs	5 to 10 years or period of patent
•  patent rights	period of patent
•  marketing authorisations	indefinite life or period of marketing authorisation
•  product rights	10 to 15 years
•  commercial relationships	7 years
•  brand	3 to 10 years
•  acquired capitalised development costs	5 to 15 years
•  pharmacological process	10 years

The pharmacological process and capitalised developed technology from the acquisitions of Putney Inc. and AST Farma B.V. and Le Vet Beheer B.V. respectively are amortised on a reducing balance method at a rate of 20% over a 10 year life based on the expected profile of future cash flows. All amortisation on a reducing balance methodology is recognised within selling and general administrative expenses with the exception of that in respect of the pharmacological process which is recognised within research and development expenses.

The amortisation of the intangible assets are classified as an administrative expense because they relate to the right to sell and distribute the product. Within the acquired intangibles the product rights encompass market authorisations, and the capitalised development costs encompass product authorisations subject to regulatory approval. The pharmacological process is classified as a research and development expense as it relates to the process of taking a product through to registration.

When considering the basis of amortisation for our acquired intangibles, we consider a number of factors: the different market conditions which surround the intangible, the age of the products within developed technology and their corresponding place within the lifecycle of the product.

(i) Inventories

Inventories are stated at the lower of cost and net realisable value. Net realisable value is the estimated selling price in the ordinary course of business, less the estimated costs of completion and selling expenses.

The cost of inventories is determined on the first-in, first-out principle and includes expenditure incurred in acquiring the inventories and bringing them to their existing location and condition. In the case of manufactured inventories and work in progress, cost includes an appropriate share of overheads based on normal operating capacity.

(j) Cash and Cash Equivalents

Cash and cash equivalents comprise cash balances and call deposits. Bank overdrafts that are repayable on demand and form an integral part of the Group's cash management are included as a component of cash and cash equivalents for the purpose of the statement of cash flows.

(k) Impairment

The carrying amounts of the Group's assets are reviewed at each consolidated statement of financial position date to determine whether there is any indication of impairment. If any such indication exists, the asset's recoverable amount is estimated.

The recoverable amount of assets is the greater of their net selling price and value in use. In assessing value in use, the estimated future cash flows are discounted to their present value using an appropriate rate that reflects current market assessments of the time value of money and the risks specific to the asset. For an asset that does not generate largely independent cash inflows, the recoverable amount is determined for the cash generating unit to which the asset belongs.

For goodwill, assets that have an indefinite useful life and intangible assets that are not yet available for use, the recoverable amount is estimated at each consolidated statement of financial position date and when there is an indication that the asset is impaired.

An impairment loss is recognised whenever the carrying amount of an asset or its cash generating unit exceeds its recoverable amount. Impairment losses are recognised in the income statement.

Impairment losses recognised in respect of cash generating units are allocated first to reduce the carrying amount of any goodwill allocated to the cash generating units (group of units), and then to reduce the carrying amount of the other assets in the units (group of units) on a pro rata basis.

An impairment loss in respect of goodwill is not reversed.

In respect of other assets, an impairment loss is reversed if there has been a change in the estimates used to determine the recoverable amount.

An impairment loss is reversed only to the extent that the asset's carrying amount does not exceed the carrying amount that would have been determined, net of depreciation or amortisation, if no impairment loss had been recognised.

(l) Dividends paid

Dividends are recognised in the period in which they are approved by the Company's shareholders or, in the case of an interim dividend, when the dividend is paid.

(m) Employee Benefits

Pensions

The Group operates a stakeholder personal pension scheme for certain employees. Obligations for contributions are recognised as an expense in the income statement as incurred.

Dechra Veterinary Products SAS and Dechra Veterinary Products BV participate in state-run pension arrangements. These are not considered to be material to the Group financial statements and are accounted for as defined contribution schemes, with contributions being recognised as an expense in the income statement as incurred.

The Group sponsored defined benefit arrangements in certain countries, the most material being a defined benefit pension plan in the Netherlands. This was a funded career average pay arrangement, where pensionable salary was subject to a cap. The arrangement was funded through an insurance contract.

From 1 January 2019 the employee pension benefit in the Netherlands is being provided through contributions to a defined contribution scheme and the Group's obligations under the previous pension arrangements ceased.

The Group's net obligation in previous years in respect of defined benefit pension plans was calculated by estimating the amount of future benefit that employees had earned in return for their service in the current and prior periods.

That benefit was discounted to determine its present value, and the fair value of any plan assets is deducted. The liability discount rate is the yield at the Statement of Financial Position date using AA rated corporate bonds that have maturity dates approximating to the terms of the Group's obligations. The calculation was performed by a qualified actuary using the projected unit credit method.

All actuarial gains and losses that arose in calculating the Group's obligation in respect of a scheme were recognised immediately in reserves and reported in the consolidated statement of comprehensive income. Where the calculation resulted in a benefit to the Group, the asset recognised was limited to the present value of any future refunds from the plan or reductions in future contributions to the plan.

Share-based Payment Transactions

The Group operates a number of equity settled share-based payment programmes that allow employees to acquire shares in the Company. The Group also operates a Long Term Incentive Plan for Directors and Senior Executives.

The fair value of shares or options granted is recognised as an employee expense over the vesting period on a straight-line basis in the income statement with a corresponding movement to equity reserves. Fair values are determined by use of an appropriate pricing model and by reference to the fair value of the options granted. The amount to be expensed over the vesting period is adjusted to reflect the number of awards for which the related service and non-market vesting conditions are expected to be met, such that the amount ultimately recognised as an expense is based on the number of awards that meet the related service and non-market performance conditions at the vesting date.

At each consolidated statement of financial position date, the Group revises its estimates of the number of share incentives that are expected to vest. The impact of the revisions of original estimates, if any, is recognised in the income statement, with a corresponding adjustment to equity reserves, over the remaining vesting period.

The fair values of grants under the Long Term Incentive Plan have been determined using the Monte Carlo simulation model, as performed by a qualified third party valuation expert.

The fair values of options granted under all other share option schemes have been determined using the Black–Scholes option pricing model, as performed by a qualified third party valuation expert.

When the options are exercised, the Company issues new shares. The proceeds received net of any directly attributable transaction costs are credited to share capital (nominal value) and share premium.

National Insurance contributions payable by the Company on the intrinsic value of share-based payments at the date of exercise are treated as cash settled awards and revalued to market price at each consolidated statement of financial position date.

Bonus and Commission Payments

The Group operates sales incentives schemes for certain employees and third party sales representatives in particular territories. The related bonuses and commissions are accrued in line with the related sales revenues.

(n) Revenue Recognition

Revenue from the sale of goods is measured at the fair value of the consideration and excludes intra-group sales and value added and similar taxes. The primary performance obligation is the transfer of goods to the customer. Revenue from the sale of goods is recognised when control of the goods is transferred to the customer, at an amount that reflects the consideration to which an entity expects to be entitled in exchange for those goods. Revenue from third party manufacturing consists principally of the production of goods to customer specification together with the provision of technical services. Revenues from third party manufacturing are recognised upon completion of the work order, either the completion and agreed delivery of the product, or upon full provision of the service.

As sales arrangements differ from time to time (for example by customer and by territory), each arrangement is reviewed to ensure that revenue is recognised when control of the goods have passed to the customer.

This review and the corresponding recognition of revenue encompasses a number of factors which include, but are not limited to the following:

• reviewing delivery arrangements and whether the buyer has accepted title – we recognise the revenue at the point at which full title has passed; and/or
• where distribution arrangements are in place, recognising when the goods pass to the third party customer (for example by reviewing insurance arrangements) and recognising revenue at the point at which title has passed.

Provision for rebates, returns, discounts and other variable consideration is reflected in the transaction price at the point of recognition to the extent that it is highly probable there will not be a significant reversal. The methodology and assumptions used to estimate rebates and returns are based on the most likely method of calculation. This is adjusted in light of contractual and legal obligations, historical trends, past experience and projected market conditions. Market conditions are evaluated using wholesaler and other third party analysis, and internally generated information.

(o) Leases

Operating Leases

Payments made under operating leases are recognised in the income statement on a straight-line basis over the term of the lease. Lease incentives received are recognised in the income statement evenly over the period of the lease, as an integral part of the total lease expense.

Finance Leases

Minimum lease payments are apportioned between the finance charge and the reduction of the outstanding liability using the effective interest rate method.

(p) Net Financing Costs

Net financing costs comprise interest payable on borrowings, unwinding of discount on provisions and deferred considerations measured at amortised cost, interest receivable on funds invested, gains and losses on hedging instruments that are recognised in the income statement (see accounting policy (e)) and gains or losses on the retranslation of financial assets and liabilities denominated in foreign currencies. Interest income is recognised in the income statement as it accrues. The Group capitalises borrowing costs directly attributable to the acquisition, construction or production of a qualifying asset as part of the cost of that asset. The interest expense component of finance lease payments is recognised in the income statement using the effective interest rate method.

(q) Contingent Considerations

The Group has adopted the financial liability model when accounting for contingent consideration in respect of licensing agreements. The estimated future amounts payable for contingent consideration are recorded on initial recognition at the present value of the future cash flow payable, discounted with an appropriate discount rate, with a corresponding intangible asset recorded. The unwind of the liability, reflecting discounting for the passage of time, is recognised within the income statement as a finance expense and calculated using a risk-free discount rate. Contingent considerations are remeasured at each reporting date and any downward remeasurement of the related liability is adjusted against the intangible, with any excess over the carrying value of the intangible recognised in the income statement. Any upwards remeasurement is recognised as an increase to the intangible asset.

(r) Provisions

Provisions for legal claims, environmental remediation, deferred rent and advanced grants for property, plant and equipment are recognised when: the Group has a present legal or constructive obligation as a result of past events; it is probable that an outflow of resources will be required to settle the obligation; and the amount can be reliably estimated. Provisions are not recognised for future operating losses. Where there are a number of similar obligations, the likelihood that an outflow will be required on settlement is determined by considering the class of obligations as a whole. A provision is recognised even if the likelihood of an outflow with respect to any one item included in the same class of obligations may be small.

Provisions are measured at the present value of the expenditures expected to be required to settle the obligation using a pre-tax rate that reflects current market assessments of the time value of money and the risks specific to the obligation. The increase in the provision due to passage of time is recognised as an interest expense.

(s) Basis of Charge for Taxation

Income tax expense comprises current and deferred tax. Current and deferred taxes are recognised in the income statement except to the extent that it relates to a business combination or items recognised directly in equity or in other comprehensive income.

Current tax is the expected tax payable on the taxable income for the year using tax rates enacted or substantively enacted at the consolidated statement of financial position date, and any adjustment to tax payable in respect of previous years.

Deferred tax is provided using the consolidated statement of financial position liability method and represents the tax payable or recoverable on most temporary differences which arise between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for taxation purposes (the tax base). Temporary differences are not provided on: goodwill that is not deductible for tax purposes; the initial recognition of assets or liabilities that affect neither accounting nor taxable profit and do not arise from a business combination; and differences relating to investments in subsidiaries to the extent that they will probably not reverse in the foreseeable future. The amount of deferred tax provided is based on the expected manner of realisation or settlement of the carrying amount of assets and liabilities, and is based upon tax rates enacted or substantively enacted at the consolidated statement of financial position date.

A deferred tax asset is recognised only to the extent that it is probable that future taxable profits will be available against which the asset can be utilised. Deferred tax assets are reduced to the extent that it is not probable that the related tax benefit will be realised against future taxable profits. The carrying amounts of deferred tax assets are reviewed at each consolidated statement of financial position date.

In respect of uncertain tax positions, where an outflow of funds is believed to be probable and a reliable estimate of the outcome of the dispute can be made, management provides for its best estimate of the liability. In calculating any such liability a risk based approach is applied which takes into account, as appropriate, the probability that the Group would be able to obtain compensatory adjustments under international tax treaties.

The estimated annual benefit of global intellectual property and innovation incentives is accounted for within current and deferred tax.

Current and deferred tax credits received in respect of share-based payments are recognised in the income statement to the extent that they do not exceed the standard rate of taxation on the income statement charge for share-based payments. Credits in excess of the standard rate of taxation are recognised directly in equity.

(t) Earnings per Share

The Group presents basic and diluted earnings per share (EPS) data for its ordinary shares. Basic EPS is calculated by dividing the profit attributable to ordinary shareholders of the Company by the weighted average number of ordinary shares in issue during the period. Diluted EPS is determined by adjusting the profit attributable to ordinary shareholders and the weighted average number of ordinary shares in issue for the effects of all potential dilutive ordinary shares, which comprise share options granted to employees.

The Group has also chosen to present an alternative EPS measure, with profit adjusted for non-underlying items. A reconciliation of this alternative measure to the statutory measure required by IFRS is given in the Financial Review. A breakdown of the non-underlying items is given in note 4 and note 5.
