NOTES TO THE FINANCIAL STATEMENTS

FOR THE YEAR ENDED 31 DECEMBER 2024

1.Accounting policies

1.1

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:

1.2

Exemption from preparing consolidated financial statements

The Company, and the Group headed by it, qualify as small as set out in section 383 of the Companies Act 2006 and the parent and Group are considered eligible for the exemption to prepare consolidated accounts.

1.3

Going concern

Jackson Laboratory UK Limited is in a net asset position supported primarily by an intercompany receivable due from its parent company, Jackson Laboratory Holdings, LLC. The directors have considered the parent company's ability to provide financial support and have received written confirmation that it will continue to do so for a period of at least 12 months from the date of signing these financial statements. For this reason, the directors continue to adopt the going concern basis in preparing the financial statements.

1.4

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.

1.Accounting policies (continued)

1.5

Turnover

Turnover is recognised to the extent that it is probable that the economic benefits will flow to the Company and the turnover can be reliably measured. Turnover is measured as the fair value of the consideration received or receivable, excluding discounts, rebates, value added tax and other sales taxes. The following criteria must also be met before turnover is recognised:

Rendering of services

Intercompany revenue is recognised on a cost plus 9% basis, in line with the intercompany service agreement with the parent company.
Intercompany revenue is recognised when all of the following conditions are satisfied:

∙the amount of turnover can be measured reliably;

∙it is probable that the Company will receive the consideration due under the intercompany service agreement; and

∙the costs incurred and the costs to complete the contract can be measured reliably.

1.6

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.

1.7

Taxation

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.

1.8

Valuation of investments

Investments in subsidiaries are measured at cost less accumulated impairment.

1.9

Debtors

Short-term debtors are measured at transaction price. Amounts due from group undertakings are measured at cost. These loans are unsecured, interest free and repayable on demand.
