The cost of research and development programs is charged against income in each period.

In recent years the Company has received several awards of research and development grants by the Technology Strategy Board, a public body established by the U.K. government to stimulate technology-enabled innovation.

In 2011, the Company was awarded a research and development grant by the Technology Strategy Board to lead a collaborative project with Cummins Generator Technologies and Newcastle University in the U.K. to develop an innovative electric drive system for electric vehicles using advanced switched reluctance motor technology. The Company recorded grant income from this Technology Strategy Board project of $8,000 in the first quarter of 2015 associated with research and development expense of $23,000. The Company recorded grant income of $17,000 associated with research and development expense of $50,000 in respect of this Technology Strategy Board grant in the first quarter of 2014.
 
In July 2013, the Company was awarded a grant of approximately $480,000 by the Low Emission Transport Collaborative Projects Fund, a U.K. government body. The grant is to develop next-generation controls for high-voltage, low-power applications. This grant will defray part of the research and development expense associated with this project over the period to March 2015. The Company recorded grant income from this project in the first quarter of 2015 of $16,000 associated with research and development expense of $66,000. The Company recorded grant income from this project in the first quarter of 2014 of $97,000 associated with research and development expense of $422,000.

The grant income in the first quarter of 2015 and 2014 was recorded as a reduction of research and development expense.
