9.	LICENSING

We have sublicensed the exclusive right to manufacture and market the Autoscope and RTMS technology in North America, the Caribbean and Latin America to Econolite, and we receive royalties from Econolite on sales of systems in those territories as well as in non-exclusive territories as allowed from time to time. We may terminate our agreement with Econolite if a minimum annual sales level is not met or if Econolite fails to make royalty payments as required by the agreement. The agreement's term runs to 2031, unless terminated by either party upon three years' notice.

We recognized royalty income from this agreement of $12.4 million, $13.0 million and $12.5 million in 2012, 2011 and 2010, respectively.
