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 have been prepared under the historical cost convention, [modified to include the revaluation of freehold properties and to include investment properties and certain financial instruments at fair value]. The principal accounting policies adopted are set out below.

This company is a qualifying entity for the purposes of FRS 102, being a member of a group where the parent of that group prepares publicly available consolidated financial statements, including this company, which are intended to give a true and fair view of the assets, liabilities, financial position and profit or loss of the group. The company has therefore taken advantage of exemptions from the following disclosure requirements:

• Section 7 ‘Statement of Cash Flows’: Presentation of a statement of cash flow and related notes and disclosures;

• Section 11 ‘Basic Financial Instruments’ and Section 12 ‘Other Financial Instrument Issues: Interest income/expense and net gains/losses for financial instruments not measured at fair value; basis of determining fair values; details of collateral, loan defaults or breaches, details of hedges, hedging fair value changes recognised in profit or loss and in other comprehensive income;

• Section 26 ‘Share based Payment’: Share-based payment expense charged to profit or loss, reconciliation of opening and closing number and weighted average exercise price of share options, how the fair value of options granted was measured, measurement and carrying amount of liabilities for cash-settled share-based payments, explanation of modifications to arrangements;

• Section 33 ‘Related Party Disclosures’: Compensation for key management personnel.

The company has taken advantage of the exemption under section 400 of the Companies Act 2006 not to prepare consolidated accounts. The financial statements present information about the company as an individual entity and not about its group.

The financial statements of the company are consolidated in the financial statements of Demant A/S. The consolidated financial statements of this group are available to the public and may be obtained from Demant A/S, Kongebakken 9, 2765 Smørum, Denmark. www.demant.com

Turnover is recognised at the fair value of the consideration received or receivable for goods and services provided in the normal course of business, and is shown net of VAT and other sales related taxes. The fair value of consideration takes into account trade discounts, settlement discounts and volume rebates.

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 profit or loss.

Stock is valued at the lower of cost and estimated selling price less costs to sell. In respect of work in progress and finished goods, cost includes a relevant proportion of overheads according to the stage of manufacture/completion.

Cash and cash equivalents are basic financial assets and include cash in hand, deposits held at call with banks, other short-term liquid investments with original maturities of three months or less, and bank overdrafts. Bank overdrafts are shown within borrowings in current liabilities.

The following assets and liabilities are classified as financial instruments – trade debtors and trade creditors.

Trade debtors and trade creditors are measured at the undiscounted amount of cash or other consideration expected to be paid or received.

Changes in the fair value of derivatives that are designated and qualify as fair value hedges are recognised in profit or loss immediately, together with any changes in the fair value of the hedged asset or liability that are attributable to the hedged risk.

The tax expense represents the sum of the tax currently payable and deferred tax.

Tax deferred or accelerated is accounted for in respect of all material timing differences, in particular accelerated capital allowances. All deferred tax is charged/(credited) to the Statement of Income and Retained Earnings/Profit and Loss Account.

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

Leases are classified as finance leases whenever the terms of the lease transfer substantially all the risks and rewards of ownership to the lessees. All other leases are classified as operating leases.

Assets held under finance leases are recognised as assets at the lower of the assets fair value at the date of inception and the present value of the minimum lease payments. The related liability is included in the balance sheet as a finance lease obligation. Lease payments are treated as consisting of capital and interest elements. The interest is charged to profit or loss so as to produce a constant periodic rate of interest on the remaining balance of the liability.

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 leases asset are consumed.

Transactions in currencies other than pounds sterling are recorded at the rates of exchange prevailing at the dates of the transactions. At each reporting end date, monetary assets and liabilities that are denominated in foreign currencies are retranslated at the rates prevailing on the reporting end date. Gains and losses arising on translation in the period are included in profit or loss.
