Administrative expenses were kEUR 1,097 for the second quarter of 2015 compared to kEUR 952 in the second quarter of 2014. This increase of kEUR 145 was primarily due to increased headcount related to the pursuit of our growth strategy.

Research and development (“R&D”) expenses increased to kEUR 1,417 in the second quarter of 2015 from kEUR 831 in the prior year period, as we continued to invest heavily in R&D with a number of active projects in various stages of development.

Operating loss was kEUR 2,095 in the second quarter of 2015, compared to an operating loss of kEUR 1,379 in the prior year period. Our increased operating loss in the second quarter of 2015 was the result of an increase in our operating expenses caused by higher selling as well as research and development expenses and increased headcount related to the pursuit of our growth strategy.
