Okay.
As we mentioned in the opening speech, CSTT operates on a full cost recovery basis. In simple terms, that means we're focused on key areas of surface transportation technology, but more so on the engineering consulting side of the business to leverage the unique testing infrastructure we have on site on our campus. It's a 45-acre campus east of the Ottawa airport.
Over the years, the breakdown in business activity that we've undertaken, road versus rail, has been, if I recall, about 80% on what we define as the road vehicle side and about 20% on what we define as the rail side. That percentage is not based an allocation of money from CSTT or through any program. It's based on market attractiveness, meaning market pull from clients we've been able to identify who are interested in the unique testing infrastructure, skills, knowledge, and capabilities that CSTT possesses.
Of course, in every piece of business we do in transportation, we're always keen on looking for an opportunity to enhance our value with that key client and to working toward a contracted type of R and D scenario.
