Brief mention of VHC 2011 royalty payment, and rights to future VHC royalties.

"With respect to profitability, operating margin for the year on an ex-CityTime basis finished at 7.7%, down 100 basis points from fiscal '11. The bulk of this reduction was driven by a couple of special items. First we had, as you might recall, a $55 million pickup in the prior year, fiscal '11, from a royalty payment we received from VirnetX. We did not receive any royalty payments in fiscal '12, but we still have rights to receive royalties in the future as VirnetX continues to pursue additional infringement cases against top-tier technology firms. Second, we had about $35 million in unplanned intangible impairments and legal-related costs in fiscal '12. Together, those 2 categories accounted for 90 basis points of margin reduction year-over-year."
