Thank you Jason and good morning everyone. Teledyne’s reported first quarter sales of $565 million. Excluding the impact of foreign currency, sales were largely flat with last year. Due to continued operating discipline and cost reductions, GAAP operating margin increased 40 basis points to 11.9% and gross margin was at an all time record. Despite lower revenue and a tax benefit of $0.06 per share in 2014, GAAP earnings per share were flat year-over-year. During the quarter, a number of technical and product introduction milestones were accomplished. We shipped our first uncalled or micro bolometers based infrared cameras that incorporate proprietary imaging algorithms. We have significant sales related to our new ultra high power subsea connectors. We successfully demonstrated state of the art guided musician’s technology referred to as EXACTO. And we received the largest single after market avionics order in the company's history. Teledyne continues to have a broad and balanced portfolio of highly engineered products and our business is diversified and resilient to changes in specific end markets. Given the old prices and more precisely excess exploration vessel capacity, we expected a decline in certain offshore energy markets. In January of this year we specifically mentioned that certain energy businesses such as geophysical sensors used in offshore oil exploration could decline as much as 25% to 35% in 2015. We continue to believe this will be the case but for a perspective this particular business represents less than 5% of Teledyne’s total revenue. However, as all exploration related revenue declined year-over-year, our business related to offshore energy production reported record sales and the backlog remains healthy given strong orders for new product and market share gains. In other markets environmental instrumentation and avionics grew nicely from last year offsetting some declines in our U.S. government businesses. In the first quarter sales to the U.S. government which represented about 24% of total sales declined with much of the shortfall related to timing and orders and shipments and some gaps in ongoing programs. Foreign currency translation primarily impacted our instrumentation and digital imaging segments, but acquisitions help mitigate these declines. In our commercial businesses, total sales increased slightly both in the U.S. and internationally. Reported revenue even net of FX translation was stable in all major global regions with a notable exception of Europe. In the near-term we are not counting on a pickup in the global economy or a moderation in foreign currency headwinds. Also last year we benefitted by approximately $0.50 per share in earnings from tax benefit including the R&D tax credit as well as net legal settlement. Furthermore, despite freezing our non-qualified pension plan for the top 20 executives, non-cash pension expense has increased due to the lower discount rate in 2015. Because of these points we believe a more cautious view on sequential earnings improvement is prudent. And we have modestly adjusted our prior full year outlook by $0.11 a share or just shy of 2%. Teledyne’s success depends on our ability to manage change, both operationally and strategically across our portfolio of businesses. In those businesses that are growing, we are continuing to invest. In others we are staying nimble and aggressively managing cost. Also we will continue to make acquisitions to generate long-term growth as well as attractive return on invested capital through implementation of operational excellence in our acquired businesses. I will now comment on our business segment after which Sue Main will review some of the financials in more detail and provide an earnings outlook for the second quarter and full years 2015. Turning to the instrumentation segment, first quarter sales increased 4.4% from last years. Sales of marine instrumentation increased 5.9% despite a significant expected year-over-year decline in the sales of geophysical sensors that I previously mentioned. We also had of course negative impact of foreign currency which impacted this group specifically. As I mentioned previously, sales to offshore energy production industry remained very strong, robust stores continued resulting in stable backlog in businesses primarily serving this market. In the environmental domain, sales increased 10.4% which was all organic and reflected increased sales of both laboratory and field instrumentation as well as greater sales of air monitoring and gas process analysis. Sales of electronic to measurement systems declined with roughly half of the decline due to foreign currency translation. GAAP segment operating profit increased and operating margin improved 109 basis points due to higher sales and improved operating performance specially within the environmental instrument group. Turning to the digital imaging segment, first quarter sales decreased 11.3% compared to last year’s primarily due to lower sales from U.S. government R&D contract as well as specialty centers for remote sensing applications. These were partially offset by higher sales of x-ray sensors for medical imaging. Sales of cameras for general industrial machine vision applications increased slightly but were offset by declines in sales of cameras or semiconductor and electronic inspection. The year-over-year decline in government R&D is largely due to the conclusion of DARPA's extreme accuracy tasked ordinance program also known as EXACTO or the guided bullet. Nevertheless a milestone was reached in February during live fire demonstration which showed that the EXACTO was able to hit moving and evading targets with extreme accuracy at sniper ranges unachievable with traditional rounds. We are hopeful that additional funding will become available for these and similar programs later this year. GAAP operating margin continued to increase and was 77 basis points greater than last year. Turning to aerospace and defense electronic segments, first quarter sales decreased minus 7.9% while U.S. government sales declined or commercial avionics businesses continued to perform very well. Operating profit declined due to lower sales and lower margins in a number of defense electronic businesses. However, due to cost reduction efforts and an increase on orders recently, we expect improved sales and margins in the balance of the year. Turning to the engineer systems segment, first quarter revenue increased 6.2% and operating margin increased 35 basis points. Both sales and margin benefitted from the greater mix of marine and space manufacturing programs and higher sales of energy system products such as commercial, hydrogen generators. In conclusion, through acquisitions and strong cost control we were able to mitigate headwinds from foreign exchange and the timing of certain government programs. We are also confident about sequential earnings improvement. However, we do not want to be overly optimistic or plan for a significant second hand recovery in the global economy for our specific end markets. And finally our strategy remains the same. First, focus on highly engineered products for specialized end markets. Second, a commitment to operational excellence to improve margins. And third, continued investment including greater emphasis on acquisitions to grow our portfolio of businesses. I will now turn the call over to Sue Main.
