(1) Tax credit applicable in Norway (uplift). The determined uplift rate is 5.5% pa. The uplift is calculated based on the capitalised investment expenditure (offshore production installation) and is settled against taxable income over a period of four years from the year the expenditure was incurred. Any uplift unused in a given period may be settled in the future until fully used, with no time limit. The amount of LOTOS Production and Exploration Norge AS’s unused uplift increased the deferred tax asset under the Group’s tax losses settled over time, and had no effect on tax disclosed in the consolidated statement of comprehensive income.

Taxable temporary differences are expected to expire in 2016–2083.

As at December 31st 2015, the value of unrecognised tax assets on account of tax losses was PLN 683 thousand (December 31st 2014: PLN 63,025 thousand). The decrease in the amount of the unrecognised tax assets results from a partial settlement of relevant tax losses, as well as from the loss of the right to deduct tax losses due to expiry of the period when the tax losses could be settled in accordance with the tax regulations.
