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 estimates and assumptions which have a significant risk of causing a material adjustment to the carrying amount of assets and liabilities are as follows:
Revenue recognition
The key judgements made by management in respect of revenue is the point at which that revenue should be recognised. Management consider the underlying contract terms and conclude upon the most appropriate point of the cycle at which to recognise revenue based upon the these terms and in particular where the risks and rewards of ownership transfer.
Tangible fixed assets
Tangible fixed assets are depreciated over their useful lives taking into account residual values, where appropriate. The actual lives of the assets and residual values are assessed annually and may vary depending on a number of factors. Residual value assessment consider issues such as the remaining life of the asset and the projected disposal value.
