Research and Development ("R&D"). R&D costs increased significantly as we devoted increased engineering personnel resources to the development of our next generation Omni-series motor control unit and charger, as well as the continued testing of our EV vehicles, new battery technologies and electric motors. We also continued to allocate necessary resources to the development and testing of upgraded proprietary control software and DC-DC converters.
Selling, General, and Administrative Expenses ("S, G & A"). S, G & A is comprised of activities in the executive, finance, marketing, field service and quality departments' compensation as well as related payroll benefits, and non-cash charges for depreciation and options expense. The Company's cost savings measures continue to be sustained and have become an integral part of the sales environment in 2011. The Company constantly evaluates contemporary or fully matured cost measures in the event of potential or future growth changes.
Interest and Other Income (Expense). Interest and other expense increased in 2011 due to a loss in connection with a litigation settlement of $41,000 which we did not have in 2010.
