The effective tax rate in 2018 was positively impacted by the geographical spread.

In various countries, DSM has taken standpoints regarding its tax position which may at any time be challenged, or have already been challenged, by the tax authorities, because the authorities in question interpret the law differently. These uncertainties are taken into account in determining the probability of realization of deferred tax assets and liabilities.

The deferred tax assets and liabilities relate to the following balance sheet items:

No deferred tax assets were recognized for loss carryforwards amounting to €237 million (2017: €211 million). Unrecognized loss carryforwards amounting to €58 million will expire in the years up to and including 2023 (2017: €77 million up to and including 2022), €112 million between 2024 and 2028 (2017: €72 million between 2023 and 2027) and the remaining €67 million between 2029 and beyond (2017: €63 million between 2028 and 2032).

The valuation of deferred tax assets depends on the probability of the reversal of temporary differences and the utilization of tax loss carryforwards. Deferred tax assets are recognized for future tax benefits arising from temporary differences and for tax loss carryforwards to the extent that the tax benefits are likely to be realized. In the Netherlands, tax losses may be carried forward for six years. DSM has to assess the likelihood that deferred tax assets will be recovered from future taxable profits. Deferred tax assets are reduced if, and to the extent that, it is not probable that all or some portion of the deferred tax assets will be realized. In the event that actual future results differ from estimates, and depending on tax strategies that DSM may be able to implement, changes to the measurement of deferred taxes could be required, which could impact on the company's financial position and profit for the year.
