1. Accounting policies

The principal accounting policies are summarised below. They have all been applied consistently throughout the financial year and to the preceding financial year, unless otherwise stated.

General information and basis of accounting

Mantissa Limited (the Company) is a private company, limited by shares, incorporated in the United Kingdom under the Companies Act 2006 and is registered in England and Wales. The address of the Company's registered office is C/O Mcbrides Accountants Llp Nexus House, 2 Cray Road, Sidcup, DA14 5DA, United Kingdom.

The financial statements have been prepared under the historical cost convention, modified to include certain items at fair value, and in accordance with Section 1A of Financial Reporting Standard 102 (FRS 102) ‘The Financial Reporting Standard applicable in the UK and Republic of Ireland’ issued by the Financial Reporting Council and the requirements of the Companies Act 2006 as applicable to companies subject to the small companies regime.

The financial statements are presented in pounds sterling which is the functional currency of the Company and rounded to the nearest £.

Going concern

The director has assessed the Balance Sheet and likely future cash flows at the date of approving these financial statements. The director has a reasonable expectation that the Company has adequate resources to continue in operational existence and to meet its financial obligations as they fall due for at least 12 months from the date of signing these financial statements. Accordingly, they continue to adopt the going concern basis in preparing the financial statements.

Turnover

Turnover comprises the fair value of the consideration received or receivable for the sale of goods and provision of services in the ordinary course of the company’s activities. Turnover is shown net of sales/value added tax, returns, rebates and discounts and after eliminating sales within the company. The company recognises revenue when:

- the amount of revenue can be reliably measured;
- it is probable that future economic benefits will flow to the entity;
- and specific criteria have been met for each of the company's activities.

Taxation

Current tax
The tax expense for the period comprises current 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 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.

Deferred tax
Deferred tax arises as a result of including items of income and expenditure in taxation computations in periods different from those in which they are included in the Company's financial statements. Deferred tax is provided in full on timing differences which result in an obligation to pay more or less tax at a future date, at the average tax rates that are expected to apply when the timing differences reverse, based on current tax rates and laws. Deferred tax assets and liabilities are not discounted.

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.

Intangible assets

Intangible assets are stated at cost or valuation, net of amortisation and any provision for impairment. Amortisation is provided on all intangible assets at rates to write off the cost or valuation of each asset over its expected useful life as follows:

Development costs

33 % reducing balance

Research and development

Development expenditure is also written off, except where the director is satisfied as to the technical, commercial and financial viability of individual projects. In such cases, the identifiable expenditure is capitalised as an intangible asset and amortised over the period during which the Company is expected to benefit. This period is between three and five years. Provision is made for any impairment.

Other intangible assets

Intangible assets are initially recognised at cost. After recognition, under the cost model, intangible assets are measured at cost less any accumulated amortisation and any accumulated impairment losses.

All intangible assets are considered to have a finite useful life. If a reliable estimate of the useful life cannot be made, the useful life shall not exceed ten years.

Tangible fixed assets

Tangible fixed assets are stated at cost or valuation, net of depreciation and any provision for impairment. Depreciation is provided on all tangible fixed assets, other than investment property and freehold land, at rates calculated to write off the cost or valuation, less estimated residual value, of each asset on a straight-line or reducing balance basis over its expected useful life, as follows:

Plant and machinery etc.

15 % reducing balance

Residual value represents the estimated amount which would currently be obtained from disposal of an asset, after deducting estimated costs of disposal, if the asset were already of the age and in the condition expected at the end of its useful life.

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.

Impairment of assets

Assets, other than those measured at fair value, are assessed for indicators of impairment at each Balance Sheet date. If there is objective evidence of impairment, an impairment loss is recognised in the Profit and Loss Account as described below.

Non-financial assets
At each balance sheet date, the company reviews its tangible and intangible 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). The recoverable amount of an asset is the higher of its fair value less costs to sell and its value in use. In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset for which the estimates of future cash flows have not been adjusted.

Where it is not possible to estimate the recoverable amount of an individual asset, the company estimates the recoverable amount of the cash-generating unit to which the asset belongs. An impairment loss is recognised immediately in profit or loss, unless the relevant asset is carried at a revalued amount, in which case the impairment loss is treated as a revaluation decrease.

Trade and other debtors

Trade and other debtors are recognised initially at the transaction price. They are subsequently measured at amortised cost using the effective interest method, less provision for impairment, except where the effect of discounting would be immaterial. In such cases debtors are stated at transaction price less impairment losses. 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 transaction.

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 and other creditors

Trade and other creditors are recognised initially at the transaction price. They are subsequently measured at amortised cost using the effective interest method, except where the effect of discounting would be immaterial. In such cases creditors are stated at transaction price.

Financial instruments

Classification

Financial instruments are classified and accounted for, according to the substance of the contractual arrangement, as either financial assets, financial liabilities or equity instruments. An equity instrument is any contract that evidences a residual interest in the assets of the company after deducting all of its liabilities.

Financial assets are classified as financial assets at fair value through profit or loss, loans and debtors, held-to-maturity investments, available-for-sale financial assets, or as derivatives designated as hedging instruments in an effective hedge, as appropriate. The company determines the classification of its financial assets at initial recognition.

Financial liabilities are classified as financial liabilities at fair value through profit and loss, loans and borrowings, trade and other creditors, or as derivatives designated as hedging instruments in an effective hedge, as appropriate. The company determines the classification of its financial liabilities at initial recognition.

Recognition and measurement

All financial instruments are recognised initially at fair value plus transaction costs. Thereafter financial instruments are stated at amortised cost using the effective interest rate method (less impairment where appropriate) unless the effect of discounting would be immaterial in which case they are stated at cost (less impairment where appropriate). The exception to this are those financial instruments where it is a requirement to continue recording them at fair value through profit and loss.

Provisions

Provisions are recognised when the Company has a present obligation (legal or constructive) 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 Balance Sheet date, taking into account the risks and uncertainties surrounding the obligation. Where a provision is measured using the cash flows estimated to settle the present obligation, its carrying amount is the present value of those cash flows (when the effect of the time value of money is material).

When some or all of the economic benefits required to settle a provision are expected to be recovered from a third party, a receivable is recognised as an asset if it is virtually certain that reimbursement will be received and the amount of the receivable can be measured reliably.
