The valuation of an asset is one of the most important thing with accounting, though one of the most difficult thing as well. However, in deciding useful service life for an intangible asset and property, plant and equipment, there are quite a margin for the companies, which creates a difference between companies and industries. When computing the value of the inventories there are a few possibilities available for the companies, which also can generate differences

between companies and industries. Although these differences can occur, there might be some similarities in the companies’ estimates. Hence, the purpose of this essay is to establish whether there are any differences in how companies are assessing their useful service life of intangible assets, property, plant and equipment and deciding the value of inventories. To be able to accomplish the purpose, company’s annual reports were used along with other necessary sources, for instance books about accounting principles and theories. The study, furthermore, concluded that there are small differences between companies within the same industry and industries altogether, in their judgment on useful service life and the value of the inventories.
