[1] As mentioned above, since July 2014, the Company has been a resident of Israel and not The Netherlands for tax purposes. Therefore, prior to July 2014 "domestic" represented taxing under the Dutch tax authorities and as of July 2014 "domestic" represents taxing under the Israeli tax authorities. Thus, in the periods prior to July 2014 taxing under the Israeli tax authorities is included in the table above as foreign profit (loss) before taxes on income.
