One of the challenges for us is that the design requirements are a lot more stringent in North America. Typically, when we design a product, it has more specifications and it's more ruggedized, I'll say, than it would be in some of the international markets. So when we develop the product it tends to have a higher cost structure than some of the other international markets, where the requirements aren't as stringent.
Also, because of those requirements, which we're very familiar with, there's probably more competition outside the U.S. and Canada where we do not have the economies of scale to be as cost-competitive. In that instance, the way we succeed is in creating a custom product that the customer really wants, versus our competition, so we need to have a really strong relationship with the customer. For us, we have to invest in having the right sales force and the right time in the market in order to be successful.
