1a and 2: In the Netherlands companies pay VPB (company tax). When a company pays the tax after a certain date, they have to pay interest over the amount outstandig. The €173 is the interest paid over €12.621 company tax. Hope this makes sense. 1B YSS R&D pays a monthly advisor fee to YSS Suspension Service. In the period up till the end of Q3, 1 monthly payment had not been made, so it has te be paid still. Therefore this payment has been put on the balance sheet as a debt, so the costs are correct for 9 months.
