General information

Phlux Technology Limited is a private Company limited by shares, incorporated in England and Wales (registered number: 12908876). It's registered office is Block 5, Level 2, Pennine Five Campus, 18 Hawley Street, Sheffield, S1 4WP. The prinicpal activity of the Company throughout the year continued to be that of the design and manufacturing of avalanche photodiodes for us in a variety of sensing applications.

2.Accounting policies

 
2.1

Basis of preparation of financial statements

The financial statements have been prepared under the historical cost convention unless otherwise specified within these accounting policies and in accordance with FRS 102 'The Financial Reporting Standard applicable in the UK and the Republic of Ireland' and the requirements of the Companies Act 2006. 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 following principal accounting policies have been applied:

 
2.2

Foreign currency translation

Functional and presentation currency

The Company's functional and presentational currency is pounds sterling.

Transactions and balances

Foreign currency transactions are translated into the functional currency using the spot exchange rates at the dates of the transactions.

At each period end foreign currency monetary items are translated using the closing rate. Non-monetary items measured at historical cost are translated using the exchange rate at the date of the transaction and non-monetary items measured at fair value are measured using the exchange rate when fair value was determined.

Foreign exchange gains and losses resulting from the settlement of transactions and from the translation at period-end exchange rates of monetary assets and liabilities denominated in foreign currencies are recognised in profit or loss except when deferred in other comprehensive income as qualifying cash flow hedges.

Foreign exchange gains and losses that relate to borrowings and cash and cash equivalents are presented in the Statement of Income and Retained Earnings within 'finance income or costs'. All other foreign exchange gains and losses are presented in profit or loss within 'other operating income'.

FOR THE YEAR ENDED 31 DECEMBER 2024

2.Accounting policies (continued)

 
2.3

Revenue

Revenue 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:

Sale of goods

Revenue from the sale of goods is recognised when all of the following conditions are satisfied:
the Company has transferred the significant risks and rewards of ownership to the buyer;
the Company retains neither continuing managerial involvement to the degree usually associated with ownership nor effective control over the goods sold;
the amount of revenue can be measured reliably;
it is probable that the Company will receive the consideration due under the transaction; and
the costs incurred or to be incurred in respect of the transaction can be measured reliably.

Rendering of services

Revenue from a contract to provide services is recognised in the period in which the services are provided in accordance with the stage of completion of the contract when all of the following conditions are satisfied:
the amount of revenue can be measured reliably;
it is probable that the Company will receive the consideration due under the contract;
the stage of completion of the contract at the end of the reporting period can be measured reliably; and
the costs incurred and the costs to complete the contract can be measured reliably.

 
2.4

Operating leases: the Company as lessor

Rentals paid under operating leases are charged to the Statement of Income and Retained Earnings on a straight line basis over the lease term.

 
2.5

Research and development

In the research phase of an internal project it is not possible to demonstrate that the project will generate future economic benefits and hence all expenditure on research shall be recognised as an expense when it is incurred. Intangible assets are recognised from the development phase of a project if and only if certain specific criteria are met in order to demonstrate the asset will generate probable future economic benefits and that its cost can be reliably measured. The capitalised development costs are subsequently amortised on a straight-line basis over their useful economic lives, which range from 3 to 6 years.
If it is not possible to distinguish between the research phase and the development phase of an internal project, the expenditure is treated as if it were all incurred in the research phase only.

NOTES TO THE FINANCIAL STATEMENTS
FOR THE YEAR ENDED 31 DECEMBER 2024

2.Accounting policies (continued)

 
2.6

Government grants

Grants relating to expenditure on tangible fixed assets are credited to the Statement of Income and Retained Earnings at the same rate as the depreciation on the assets to which the grant relates. The deferred element of grants is included in creditors as deferred income.
Grants of a revenue nature are recognised in the Statement of Income and Retained Earnings in the same period as the related expenditure.

 
2.7

Pensions

Defined contribution pension plan

The Company operates a defined contribution plan for its employees. A defined contribution plan is a pension plan under which the Company pays fixed contributions into a separate entity. Once the contributions have been paid the Company has no further payment obligations.

The contributions are recognised as an expense in the Statement of Income and Retained Earnings when they fall due. Amounts not paid are shown in accruals as a liability in the Balance Sheet. The assets of the plan are held separately from the Company in independently administered funds.

 
2.8

Taxation

Tax is recognised in the Statement of Income and Retained Earnings.

The current tax charge is calculated on the basis of tax rates and laws that have been enacted or substantively enacted by the Balance Sheet date in the countries where the Company operates and generates income.

FOR THE YEAR ENDED 31 DECEMBER 2024

2.Accounting policies (continued)

 
2.9

Tangible fixed assets

Tangible fixed assets under the cost model are stated at historical cost less accumulated depreciation and any accumulated impairment losses. Historical cost includes expenditure that is directly attributable to bringing the asset to the location and condition necessary for it to be capable of operating in the manner intended by management.

Depreciation is charged so as to allocate the cost of assets less their residual value over their estimated useful lives, as follows.

The depreciation rates used are:

Leasehold improvements
-
various
Plant and machinery
-
15% straight line
Fixtures and fittings
-
15% straight line
Computer equipment
-
33% straight line
Lab and electronic test equipment
-
15% straight line

The assets' residual values, useful lives and depreciation methods are reviewed, and adjusted prospectively if appropriate, or if there is an indication of a significant change since the last reporting date.

Gains and losses on disposals are determined by comparing the proceeds with the carrying amount and are recognised in the Statement of Income and Retained Earnings.

 
2.10

Financial instruments

The Company only enters into basic financial instrument transactions that result in the recognition of financial assets and liabilities such as bank and cash balances, trade and other accounts receivable and payable, loans from banks and other third parties, and loans to and from related parties.
Debt instruments (other than those wholly repayable or receivable within one year), including loans and other accounts receivable and payable, are initially measured at the transaction price and subsequently at amortised cost using the effective interest method. Debt instruments that are payable or receivable within one year, typically trade payables or receivables, are measured, initially and subsequently, at the undiscounted amount of the cash or other consideration expected to be paid or received. However, if the arrangements of a short-term instrument constitute a financing transactions, the financial asset or liability is measured, initially, at the present value of the future cash discounted at a market rate of interest for a similar debt instrument and subsequently amortised cost.
Financial asserts and liabilities are offset and the net amount reported in the Balance Sheet when there is an enforceable right to set off the recognised amounts and there is an intention to settle on a net basis or to realise the asset and settle the liability simultaneously.
