2 | Accounting policies

Summary of significant accounting policies and key accounting estimates

The principal accounting policies applied in the preparation of these financial statements are set out below. These policies have been consistently applied to all the years presented, unless otherwise stated.

Statement of compliance

These financial statements have been prepared in accordance with Financial Reporting Standard 102 Section 1A smaller entities - 'The Financial Reporting Standard applicable in the United Kingdom and Republic of Ireland' and the Companies Act 2006 (as applicable to companies subject to the small companies' regime).

Basis of preparation

These financial statements have been prepared using the historical cost convention except that as disclosed in the accounting policies certain items are shown at fair value.

Revenue recognition

Turnover comprises the fair value of the consideration received or receivable from the US parent company in relation to the provision of services in respect of software development. Turnover is sown net of sales, returns, rebates and discounts.

Foreign currency transactions and balances

Transactions in foreign currencies are initially recorded at the functional currency rate prevailing at the date of the transaction. Monetary assets and liabilities denominated in foreign currencies are retranslated into the respective functional currency of the entity at the rates prevailing on the reporting period date. Non-monetary items carried at fair value that are denominated in foreign currencies are retranslated at the rate on the date when the fair value is re-measured.
Non-monetary items measured in terms of historical cost in a foreign currency are not retranslated.

Tax

The tax expense for the period comprises current tax payable.

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

Cash and cash equivalents

Cash and cash equivalents comprise cash on hand and call deposits, and other short-term highly liquid investments that are readily convertible to a known amount of cash and are subject to an insignificant risk of change in value.

Debtors

Trade debtors are amounts due from customers for merchandise sold or services performed in the ordinary course of business.

Notes to the Unaudited Financial Statements for the Year Ended 31 December 2025

Stocks

Stocks are stated at the lower of cost and estimated selling price less costs to complete and sell.

Trade creditors

Trade creditors are obligations to pay for goods or services that have been acquired in the ordinary course of business from suppliers.

Borrowings

Interest-bearing borrowings are initially recorded at fair value, net of transaction costs. Interest-bearing borrowings are subsequently carried at amortised cost, with the difference between the proceeds, net of transaction costs, and the amount due on redemption being recognised as a charge to the Profit and Loss Account over the period of the relevant borrowing.
Interest expense is recognised on the basis of the effective interest method and is included in interest payable and similar charges.
Borrowings are classified as current liabilities unless the company has an unconditional right to defer settlement of the liability for at least twelve months after the reporting date.

Share capital

Ordinary shares are classified as equity. Equity instruments are measured at the fair value of the cash or other resources received or receivable, net of the direct costs of issuing the equity instruments. If payment is deferred and the time value of money is material, the initial measurement is on a present value basis.

3 | Staff numbers

The average number of persons employed by the company (including directors) during the year, was 2 (2024 - 2).

company is well placed to manage its business risks successfully despite the current uncertain economic
outlook.
The directors have a reasonable expectation that the company has adequate resources to continue in
operational existence for the foreseeable future. Thus, they continue to adopt the going concern basis of
accounting in preparing the financial statements.
