The directors of the company have elected not to include a copy of the income and expenditure account within the financial statements.true

These financial statements have been prepared and delivered in accordance with the provisions applicable to companies subject to the small companies regime.

Internet Advertising Bureau is a private company limited by guarantee incorporated in England and Wales. The registered office is 11 Keeley Street, London, WC2B 4BA.

These financial statements have been prepared in accordance with FRS 102 “The Financial Reporting Standard applicable in the UK and Republic of Ireland” (“FRS 102”) and the requirements of the Companies Act 2006 as applicable to companies subject to the small companies regime. 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 financial statements are prepared in sterling, which is the functional currency of the company. Monetary amounts in these financial statements are rounded to the nearest £.

The financial statements have been prepared under the historical cost convention. The principal accounting policies adopted are set out below.

Turnover represents the amounts due from members to fund the administration of the company and planned programmes as described in the principal activities, other amounts due from members and amounts received to sponsor specific events.

Tangible fixed assets are initially measured at cost and subsequently measured at cost or valuation, net of depreciation and any impairment losses.

Depreciation is recognised so as to write off the cost or valuation of assets less their residual values over their useful lives on the following bases:

The gain or loss arising on the disposal of an asset is determined as the difference between the sale proceeds and the carrying value of the asset, and is credited or charged to surplus or deficit.

At each reporting period end date, the company reviews the carrying amounts of its tangible assets to determine whether there is any indication that those assets have suffered an impairment loss. If any such indication exists, the recoverable amount of the asset is estimated in order to determine the extent of the impairment loss (if any).

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

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

The tax currently payable is based on taxable profit for the year. Taxable profit differs from net profit as reported in the profit and loss account because it excludes items of income or expense that are taxable or deductible in other years and it further excludes items that are never taxable or deductible. The company’s liability for current tax is calculated using tax rates that have been enacted or substantively enacted by the reporting end date.

The company is a non profit making body and therefore corporation tax is only chargeable on investment income and profit, if any, arising on sponsorship, marketing, training and attendance for conferences or associated events held, to the extent that those items do not form part of the members' mutual trade.

Provisions are recognised when the company has a legal or constructive present obligation as a result of a past event, it is probable that the company will be required to settle that obligation and a reliable estimate can be made of the amount of the obligation.

The amount recognised as a provision is the best estimate of the consideration required to settle the present obligation at the reporting end date, taking into account the risks and uncertainties surrounding the obligation. Where the effect of the time value of money is material, the amount expected to be required to settle the obligation is recognised at present value. When a provision is measured at present value, the unwinding of the discount is recognised as a finance cost in surplus or deficit in the period in which it arises.

The costs of short-term employee benefits are recognised as a liability and an expense.

Payments to defined contribution retirement benefit schemes are charged as an expense as they fall due.

Rentals payable under operating leases, including any lease incentives received, are charged to profit or loss on a straight line basis over the term of the relevant lease except where another more systematic basis is more representative of the time pattern in which economic benefits from the lease asset are consumed.

Current asset investments

Investments in listed company shares and other similar securities, which have been classified as current asset investments, are remeasured to market value at each balance sheet date. Gains and losses on remeasurement are recognised in profit or loss for the period.

In the application of the company’s accounting policies, the directors are required to make judgements, estimates and assumptions about the carrying amount of assets and liabilities that are not readily apparent from other sources. The estimates and associated assumptions are based on historical experience and other factors that are considered to be relevant. Actual results may differ from these estimates.

The estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognised in the period in which the estimate is revised where the revision affects only that period, or in the period of the revision and future periods where the revision affects both current and future periods.

The following judgements (apart from those involving estimates) have had the most significant effect on amounts recognised in the financial statements.

The company recognises a provision for the estimated costs of reinstating leased properties to the condition required under the terms of the relevant lease agreements. The valuation of the provision involves significant estimation uncertainty, as it is based on management's assessment of the scope of works required at lease expiry, future contractor costs and the timing of settlement.

The average monthly number of persons (including directors) employed by the company during the year was:

Included in other creditors is a balance of £7,645 (2024: £5,319) which is secured by way of a fixed charge over cash deposits.

During the period, the company entered into a new property lease which contains a clause under which the lessee has to make good dilapidations or other damage which occurs to the property during the course of the lease or restore a property to a specified condition. This provision represents a best estimate of the amount of the obligation.

The company is limited by guarantee and does not have share capital and consequently the liability of members is limited, subject to an undertaking by each member to contribute to the net assets or liabilities of the company on winding up such amounts as may be required not exceeding £1.

As the income statement has been omitted from the filing copy of the financial statements, the following information in relation to the audit report on the statutory financial statements is provided in accordance with s444(5B) of the Companies Act 2006.

The auditor's report is unqualified and includes the following:

In our opinion the financial statements:

• give a true and fair view of the state of the company's affairs as at 31 December 2025 and of its surplus for the year then ended;

• have been properly prepared in accordance with United Kingdom Generally Accepted Accounting Practice; and

• have been prepared in accordance with the requirements of the Companies Act 2006.

At the reporting end date the company had outstanding commitments for future minimum lease payments under non-cancellable operating leases, as follows:

During the year, the directors identified that a dilapidations obligation relating to leasehold premises had not been recognised in prior periods. The company has therefore restated the comparative figures to recognise the related dilapidations provision and corresponding leasehold improvement asset.
