WBI Aerodynamics UK Ltd is a private company limited by shares incorporated in England and Wales. The registered office is 483 Green Lanes, London, UK, N13 4BS.

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.

The financial statements present information about the company as a single entity.

The company is inextricably linked, both operationally and financially to SBI group. The directors of the company have received assurances from SBI Schreiber, Brand und Partner Ingenieurgesellschaft mbh, the company's immediate parent undertaking, confirming its intention to support the company for a period of at least twelve months from the date of approval of these financial statements. Having considered post year end trading and the financial results of the group and group cash reserves, and after making enquiries of the directors of the parent undertaking, the directors have a reasonable expectation that the company has adequate resources to continue in operational existence and meet its liabilities as the fall due for the foreseeable future, being a period of at least twelve months from the date these financial statements were approved. true

Turnover is recognised to the extent that it is probable that the economic benefits will flow to the company and the revenue can be reliably measured. Revenue 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 revenue is recognised:

When the outcome of a long term contract can be estimated reliably, the company recognises contract revenue and contract costs associated with the long term contract as revenue and expenses respectively by reference to the stage of completion of the contract activity at the end of the reporting period.

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 company has elected to apply the provisions of Section 11 ‘Basic Financial Instruments’ and Section 12 ‘Other Financial Instruments Issues’ of FRS 102 to all of its financial instruments.

Financial instruments are recognised in the company's balance sheet when the company becomes party to the contractual provisions of the instrument.

Basic financial assets, which include debtors and cash and bank balances, are initially measured at transaction price including transaction costs and are subsequently carried at amortised cost using the effective interest method 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. Financial assets classified as receivable within one year are not amortised.

Basic financial liabilities, including creditors, bank loans, loans from fellow group companies and preference shares that are classified as debt, 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. Financial liabilities classified as payable within one year are not amortised.

Trade creditors are obligations to pay for goods or services that have been acquired in the ordinary course of business from suppliers. Amounts payable are classified as current liabilities if payment is due within one year or less. If not, they are presented as non-current liabilities. Trade creditors are recognised initially at transaction price and subsequently measured at amortised cost using the effective interest method.

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

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.

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.

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.

For each performance obligation to be recognised over time the Company recognises revenue using an input method, based on costs incurred in the year. Revenue and attributable margin are calculated by reference to reliable estimates of the transaction price and total expected costs, after making suitable allowances for technical and other risks.

Revenue and associated margin are therefore recognised progressively as costs are incurred and as risks have been mitigated or retired. The Company has determined that this method appropriately depicts the Company’s performance in supplying its services to the customer.

When the outcome of the transaction involving the rendering of services cannot be estimated reliably, revenue is only recognised to the extent of the expenses recognised that it is probable will be recovered.

When it is probable that total contract costs will exceed total contract revenue the expected loss is recognised immediately as an expense.

The ensuing accounting requires management judgement to determine the appropriateness of calculating the revenue and profit to be recognised. This includes estimating the total expected costs to complete each performance obligation, the profitability of the obligation and the percentage of completion at the balance sheet date.

These judgements directly influence revenue and profit that can be recognised in relation to the Company’s performance obligation. Material changes in these estimates could affect the overall amounts recognised on individual performance obligations.

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