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

Tax

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

The current corporation 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.

Deferred corporation tax is recognised on temporary differences arising between the tax bases of assets and liabilities and their carrying amounts in the financial statements and on unused tax losses or tax credits in the company. Deferred corporation tax is determined using tax rates and laws that have been enacted or substantively enacted by the reporting date.
The carrying amount of deferred tax assets are reviewed at each reporting date and a valuation allowance is set up against deferred tax assets so that the net carrying amount equals the highest amount that is more likely than not to be recovered based on current or future taxable profit.

Tangible assets

Tangible assets are stated in the statement of financial position at cost, less any subsequent accumulated depreciation and subsequent accumulated impairment losses.
The cost of tangible assets includes directly attributable incremental costs incurred in their acquisition and installation.

Depreciation

Depreciation is charged so as to write off the cost of assets over their estimated useful lives, as follows:

Asset class | Depreciation method and rate
Office equipment | 25% straight line balance basis
Fixtures and fittings | 20% straight line balance basis

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.

Trade debtors

Trade debtors are amounts due from customers for merchandise sold or services performed in the ordinary course of business.
Trade debtors are recognised initially at the transaction price. They are subsequently measured at the undiscounted amount of the cash expected to be received (i.e. net of impairment). A provision for the impairment of trade debtors is established when there is objective evidence that the company will not be able to collect all amounts due according to the original terms of the receivables.

Trade creditors

Trade creditors are obligations to pay for goods or services that have been acquired in the ordinary course of business from suppliers. Accounts payable are classified as current liabilities if the company does not have an unconditional right, at the end of the reporting period, to defer settlement of the creditor for at least twelve months after the reporting date. If there is an unconditional right to defer settlement for at least twelve months after the reporting date, they are presented as non-current liabilities.
Trade creditors are recognised initially at the transaction price and subsequently measured at the undiscounted amount of the cash expected to be paid.

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.

Dividends

Dividend distribution to the company’s shareholders is recognised as a liability in the financial statements in the reporting period in which the dividends are declared.

Defined contribution pension obligation

A defined contribution plan is a pension plan under which fixed contributions are paid into a pension fund and the company has no legal or constructive obligation to pay further contributions even if the fund does not hold sufficient assets to pay all employees the benefits relating to employee service in the current and prior periods.
Contributions to defined contribution plans are recognised as employee benefit expense when they are due. If contribution payments exceed the contribution due for service, the excess is recognised as a prepayment.

Financial instruments

Classification
Basic ﬁnancial assets include trade and other debtors, cash and bank balances. Basic ﬁnancial liabilities include trade and other payables, bank loans and preference shares that are classiﬁed as debt.
Recognition and measurement
Basic financial assets are initially recognised at transaction price, 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. Such assets are subsequently carried at amortised cost using the effective interest method. Other debtors are classified as current assets if payment is due within one year or less and are initially recorded at transaction price and subsequently measured at the undiscounted amount of the cash expected to be received. Trade debtors are referred to above.
Basic financial liabilities 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. 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. Other creditors are classiﬁed as current liabilities if payment is due within one year or less and are recognised initially at transaction price and subsequently measured at the undiscounted amount of the cash expected to be paid. If not, they are presented as non-current liabilities and are recognised initially at transaction price and subsequently measured at amortised cost using the effective interest method. Trade creditors and leases are referred to above.
Impairment
At the end of each reporting period ﬁnancial assets measured at amortised cost are assessed for objective evidence of impairment. 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 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.

3 | Staff numbers
