Thank you, Jason, and good morning, everyone. We began 2018 with an outstanding quarter. We achieved record sales, record earnings per share and record operating margin for any first quarter. Total sales increased 22.9%, including organic growth of 7.9%. Our Digital Imaging segment performed exceptionally well again, with sales increasing 21.7% organically and 81.4% overall from last year. Within the Digital Imaging, we continued to benefit from industry-wide growth in machine vision and factory automation, along with new product launches and strong execution. However, the largest year-over-year organic growth was achieved from our CMOS, that is complementary metal-oxide semiconductor-based digital X-ray detectors for medical and dental applications, which produced outstanding image resolution using lower-than-normal X-ray radiation. Notwithstanding the excellent performance in our Digital Imaging segment, our strong results were well-balanced among all of our segments and within each of our segments. Sales increased organically in all segments. Every segment also contributed to our all-time record orders, with segment book-to-bill ratio ranging from 1.09 to 1.57 for a total of 1.23 for the overall company. Even excluding 1 multiyear space program in our Aerospace and Defense Electronics segment, our overall book-to-bill still exceeded 1.1. Now I'll comment on the performance of our business segments. In our Instrumentation segment, overall first quarter sales increased 2.7% from last year. Sales of marine instruments declined 4.8% and primarily reflected lower sales of sensors for energy exploration and unfavorable timing of U.S. government sales, partially offset by higher sales of sonar systems. However, marine orders exceeded sales by 12%, and we believe the outlook for both subsea defense and offshore energy continues to improve. In the environmental domain, sales increased 7.5%, largely as a result of increased sales of laboratory and life science instruments as well as continued growth in our pollution monitoring instrumentation, particularly in China. Sales of electronic test and measurement systems increased 12.1% overall and 10.4% organically. Orders and sales of protocol analyzers continued to be very strong in the first quarter. Segment operating profit declined slightly due to -- in part, to costs associated with the relocation and consolidation of certain marine instrumentation facilities from the United Kingdom to the United States. Nevertheless, operating profit for both environmental and electronic test and measurement instrumentation increased compared to last year. Turning to the Digital Imaging segment. First quarter sales increased 81.4%, and as I indicated, organic growth was 21.7%. In addition to strong growth for X-ray detectors and industrial machine vision cameras, shipments of microelectromechanical systems, or MEMS products, for handheld devices, semiconductor processing and life science applications continue to increase. Furthermore, sales of our infrared detectors for both commercial and government application also grew considerably. And finally, all of the e2v product lines were strong contributors to revenue and profit. We recently celebrated the 1 year anniversary of the acquisition of Teledyne e2v. And I want to highlight to our employees, customers and shareholders that we could not be more pleased with the people, technologies and the financial performance that e2v has added to Teledyne. GAAP segment operating margin increased 349 basis points from last year. While the first quarter of 2017 was impacted by some charges related to the e2v acquisition, 2018 operating margin, excluding these charges, would have still increased 130 basis points. In the Aerospace and Defense Electronics segment, first quarter sales increased 13 -- 17.3%, due in part to the contribution from e2v but also strong underlying organic growth of 10.3%. Commercial aerospace sales declined slightly, given some very tough aftermarket comparisons. However, sales of defense electronics increased significantly versus last year due to greater sales across a number of microwave, interconnect and manufacturing service product lines. Segment operating margin increased 146 basis points to 17.8%, primarily due to greater sales as well as improved margins. In the Engineered Systems segment, first quarter revenue increased 6.5%, largely driven by greater marine defense programs. We also enjoyed increased sales related to ballistic missile defense. Operating margin declined slightly, primarily as a result of lower fixed-price turbine engine deliveries. I should briefly comment on the new pension accounting rules. New guidance requires splitting net pension expense for income into two components, service cost and expense, which is now included in our operation; and retirement benefit cost or income, which is now below the operations on a separate line in our income statement. Our legacy pension remains overfunded and has been closed to new participants since 2004. But I mentioned this here since the new accounting rules affect our historical businesses the most, especially the Engineered Systems segment, where it impacts margins by approximately 200 basis points. For reference, we have included historical data before and after the accounting change in our earnings release. To conclude my comments, I want to first offer some perspective in our businesses and our 2018 outlook. For a number of years, I've talked about the progressive transformation of our business portfolio. First, we have exited commoditized and liability-prone businesses such as aircraft piston engines. Second, we have built scale to bolt-on and larger acquisitions, especially in high-technology instruments and digital imaging, which now comprise 64% of our portfolio. Third, we have demonstrated our ability to rapidly and successfully integrate acquired businesses, both financially and operationally. Fourth, while we are pleased with our current business portfolio, we are also continuing to pursue acquisitions, both small and large. And finally, we have matured as a company, as evidenced by our consolidated business units, strong operations management, integrated ERP systems and a lean corporate culture. Our efforts have now shifted to improving margins by focusing on our largest and most profitable customers and products and improving and streamlining all of our business processes. Lastly, we currently believe that the organic revenue growth in 2018 will be approximately 4% compared to the 3% that I stated in February of this year. I will now turn the call over to Sue.
