Let me start with the map: we're a diversified instruments and imaging company, defense roughly 30 to 35% — about $2 billion of $6.1 billion. The infrared detectors sit in Digital Imaging, just over half our sales, but most of that segment stays commercial: machine vision, medical X-ray, space. Aerospace and Defense Electronics grew about 36% last year helped by acquisitions, yet the sensor franchise is a high-quality slice of a broad industrial company, not a pure-play. That's not us — seventy-five deals in twenty-five years, mostly cash, the discipline's in the dollars.
