Further, selling expenses from voxeljet UK significantly decreased as a result of the successful restructuring, which started in the last year’s third quarter. In addition, we incurred lower expenses for travelling, trade fairs and exhibitions related to the COVID-19 situation and the associated global restrictions.
Administrative expenses slightly increased by kEUR 103 to kEUR 4,694 for the first nine months of 2020 from kEUR 4,591 in the prior year’s period. The increase was mainly due to higher unexpected advisor fees in the second quarter of 2020, mainly related to the Audit Committee Investigation as previously disclosed in the Company’s SEC filings. This was largely offset by significantly lower administrative expense from voxeljet UK as a result of the completed restructuring.
R&D expenses decreased to kEUR 4,737 for the nine months ended September 30, 2020 from kEUR 5,295 in the same period in 2019, a decrease of kEUR 558. The decrease was mainly due to lower personnel expenses as well as lower material consumption. Those expenses can vary from quarter to quarter and are usually driven by the different project types and phases.
Other operating expenses for the nine months ended September 30, 2020 were kEUR 1,958 compared to kEUR 422 in the prior year period. This was mainly due to higher losses from foreign currency transactions amounting to kEUR 1,859 for the nine months ended September 30, 2020 compared to kEUR 395 in the prior year’s period.
Other operating income was kEUR 1,258 for the nine months ended September 30, 2020 compared to kEUR 1,468 in the prior year period. The decrease was mainly due to lower gains from foreign exchange transactions amounting to kEUR 489 for the nine months ended September 30, 2020 compared to kEUR 1,088 for the comparative period in 2019. This was partially offset by a government grant received by voxeljet America in April 2020 from the United States Small Business Administration (“SBA”) under the COVID-19 funding program amounting to kEUR 295. The full amount was recognized in profit and loss, in the second quarter of 2020, as the related costs for which the grant is intended to compensate, occurred in this period and we assume that we comply with the conditions of the funding. The assessment of SBA whether we are in compliance with the conditions, has not been performed yet.
The changes in foreign currency losses and gains were primarily driven by the valuation of the intercompany loans granted by the parent company to our UK and US subsidiaries.
Operating loss was kEUR 10,490 in the nine months ended September 30, 2020 compared to an operating loss of kEUR 9,661 in the comparative period in 2019. This was primarily driven by the net impact from other operating expenses and other operating income amounted to kEUR 700 negative for the nine months ended September 30, 2020, compared to kEUR 1,046 positive for the nine months ended September 30, 2019. In addition, gross profit decreased significantly, while administrative expenses slightly increased compared to the nine months ended September 30, 2019. This was partially offset by lower operating expenses within the functions sales and marketing and R&D for the nine months ended September 30, 2020 compared to the last year’s same period.
Financial result was negative kEUR 1,119 for the nine months ended September 30, 2020, compared to a financial result of negative kEUR 487 in the comparative period in 2019. This was mainly due to higher interest expense for long-term debt which amounted to kEUR 1,094 in the nine months ended September 30, 2020, compared to kEUR 745 for the nine months ended September 30, 2019. This increase is mainly due to the fixed interest related to the second tranche of the loan granted by the European Investment Bank (“EIB”) under the Finance Contract in June 2020 amounting to kEUR 5,000, which has been drawn down in June 2020. Finance income and expense related to the revaluation of derivative financial instruments amounted to kEUR 486 and kEUR 394, respectively for the nine months ended September 2020, compared to a finance income and expense of kEUR 133 and kEUR 0, respectively in the last year’s same period.
