NOTES TO THE FINANCIAL STATEMENTS
FOR THE YEAR ENDED 31 DECEMBER 2024

1.


General information

WuXi Biologics UK Ltd is a private company limited by shares incorporated in England and Wales. The address of its registered office is 5 New Street Square, London, EC4A 3TW.

2.Accounting policies

 
2.1

Basis of preparation of financial statements

The financial statements have been prepared under the historical cost convention unless otherwise specified within these accounting policies and in accordance with FRS 102 'The Financial Reporting Standard applicable in the UK and the Republic of Ireland' and the requirements of the Companies Act 2006. The disclosure requirements of Section 1A of FRS 102 have been applied other than where additional disclosure is required to show a true and fair view.

The following principal accounting policies have been applied:

 
2.2

Going concern

After making enquiries, the directors have a reasonable expectation that the company has adequate resources to continue in operational existence and meet its liabilities as they fall due for the foreseeable future. The company has received a letter of financial support from its ultimate parent company, WuXi Biologics (Cayman) Inc. The principal customer of the company is a fellow group company, the company is therefore dependent of the performance of the group. Without such support the company would not be a going concern. The directors have reviewed the management accounting information together with the forecasts for the group and the latest financial information and are confident that the group can provide the required financial support for a period of at least 12 months from the date of approval of the financial statements. Accordingly, the directors continue to adopt the going concern basis in preparing the financial statements.  

  
2.3

Revenue

Revenue from contracts to provide sales and marketing services to the parent company is recognised in the period in which the services are provided. Revenue is recognised to the extent that is probable that the company will receive the consideration due under the contract and the amount of revenue can be measured reliably. Revenue is measured as the fair value of the consideration received or receivable, excluding value added tax. 

 
2.4

Foreign currency translation

Functional and presentation currency

The Company's functional and presentational currency is GBP.

Transactions and balances

Foreign currency transactions are translated into the functional currency using the spot exchange rates at the dates of the transactions.

At each period end foreign currency monetary items are translated using the closing rate. Non-monetary items measured at historical cost are translated using the exchange rate at the date of the transaction and non-monetary items measured at fair value are measured using the exchange rate when fair value was determined.

Foreign exchange gains and losses resulting from the settlement of transactions and from the translation at period-end exchange rates of monetary assets and liabilities denominated in foreign currencies are recognised in profit or loss except when deferred in other comprehensive income as qualifying cash flow hedges.

NOTES TO THE FINANCIAL STATEMENTS
FOR THE YEAR ENDED 31 DECEMBER 2024

2.Accounting policies (continued)

 
2.5

Pensions

Defined contribution pension plan

The Company operates a defined contribution plan for its employees. A defined contribution plan is a pension plan under which the Company pays fixed contributions into a separate entity. Once the contributions have been paid the Company has no further payment obligations.

The contributions are recognised as an expense in profit or loss when they fall due. Amounts not paid are shown in accruals as a liability in the Balance Sheet. The assets of the plan are held separately from the Company in independently administered funds.

 
2.6

Current and deferred taxation

The tax expense for the year comprises current and deferred tax. Tax is recognised in profit or loss except that a charge attributable to an item of income and expense recognised as other comprehensive income or to an item recognised directly in equity is also recognised in other comprehensive income or directly in equity respectively.

The current income tax charge is calculated on the basis of tax rates and laws that have been enacted or substantively enacted by the balance sheet date in the countries where the Company operates and generates income.

Deferred tax balances are recognised in respect of all timing differences that have originated but not reversed by the balance sheet date, except that:
The recognition of deferred tax assets is limited to the extent that it is probable that they will be recovered against the reversal of deferred tax liabilities or other future taxable profits; and
Any deferred tax balances are reversed if and when all conditions for retaining associated tax allowances have been met.

Deferred tax balances are not recognised in respect of permanent differences except in respect of business combinations, when deferred tax is recognised on the differences between the fair values of assets acquired and the future tax deductions available for them and the differences between the fair values of liabilities acquired and the amount that will be assessed for tax. Deferred tax is determined using tax rates and laws that have been enacted or substantively enacted by the balance sheet date.

 
2.7

Debtors

Short-term debtors are measured at transaction price, less any impairment. Loans receivable are measured initially at fair value, net of transaction costs, and are measured subsequently at amortised cost using the effective interest method, less any impairment.

 
2.8

Cash and cash equivalents

Cash is represented by cash in hand and deposits with financial institutions repayable without penalty on notice of not more than 24 hours. Cash equivalents are highly liquid investments that mature in no more than three months from the date of acquisition and that are readily convertible to known amounts of cash with insignificant risk of change in value.

 
2.9

Creditors

Short-term creditors are measured at the transaction price. Other financial liabilities, including bank loans, are measured initially at fair value, net of transaction costs, and are measured subsequently at amortised cost using the effective interest method.

NOTES TO THE FINANCIAL STATEMENTS
FOR THE YEAR ENDED 31 DECEMBER 2024

2.Accounting policies (continued)

 
2.10

Provisions for liabilities

Provisions are recognised when an event has taken place that gives rise to a legal or constructive obligation, a transfer of economic benefits is probable and a reliable estimate can be made.
Provisions are measured as the best estimate of the amount required to settle the obligation, taking into account the related risks and uncertainties.
 
Increases in provisions are generally charged as an expense to profit or loss.

 
2.11

Financial instruments

The Company has elected to apply the provisions of Section 11 “Basic Financial Instruments” of FRS 102 to all of its financial instruments.

Financial instruments are recognised in the Company's Balance Sheet when the Company becomes party to the contractual provisions of the instrument.

Financial assets and liabilities are offset, with 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

Basic financial assets, which include trade and other debtors, cash and bank balances, are initially measured at their transaction price (adjusted for transaction costs except in the initial measurement of financial assets that are subsequently measured at fair value through profit and loss) and are subsequently carried at their amortised cost using the effective interest method, less any provision for impairment, 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.

Discounting is omitted where the effect of discounting is immaterial. The Company's cash and cash equivalents, trade and most other debtors due with the operating cycle fall into this category of financial instruments.

  
2.12

Share based payments

The company participates in an equity settled share based payment arrangement in which share options in its parent undertaking are issued to employees of the company. See notes 3 and 12 for further details of this scheme.


3.


Judgments in applying accounting policies and key sources of estimation uncertainty

In the application of the company's accounting policies, which are detailed in note 2, the only key judgement made by the directors is:

Share based payments
The company participates in an equity settled share based payment arrangement in which share options in its parent undertaking are issued to employees of the company. The fair value of the options at the date of grant is charged to the profit and loss account over the vesting period. Non-market vesting conditions are taken into account by adjusting the number of equity instruments expeceted to vest at each balance sheet date so that, ultimately, the cumulative amount recognised over the vesting period is based on the number of options that eventually vest. The share based payment arrangment for the year ended 31 December 2024 is detailed in note 12.
