Thanks Howard and good morning all. Earlier today we reported earnings of $2.56 per diluted share and revenue just shy of $9.3 billion. Operating earnings of slightly over $1 billion and net income of $745 million. Revenue was up 23% against the first quarter of 2018 due in large part to the acquisition of CSRA However, without CSRA revenue was up an impressive 9.6% on a purely organic basis. In fact, there was organic revenue growth across all five operating segments. EPS of $2.56 was $0.14 better than consensus, it would appear that revenue was some $400 million higher than anticipated by the sell - side and operating earnings were up about $40 million higher. Operating earnings of slightly over $1 billion were just ahead of the year-ago result despite modest declines at aerospace, marine and combat systems. The result benefited from the combination of CSRA with GDIT. The operating margin of 10.9% in the quarter was good, it did not compare favorably last year's stellar first quarter of 13.4% which was before the inclusion of amortization from CSRA transaction. Net earnings were down $54 million over the same quarter in 2018. Higher interest expense, somewhat higher taxes were the cause of lower net income. It follows that earnings per share from continuing operations were $0.09 below the first quarter 2018, a 3% drop. Apart from the impressive revenue growth, an important part of the story in the quarter was order intake and growth in backlog. Total backlog grew to $69.2 billion, an increase of $1.34 billion compared to the end of last year. Excluding the impact of foreign exchange, the book-to-bill for the company was an impressive 1.2. Broken down into 1.1 to 1 for defense and 1.4 to 1 for aerospace. So let me discuss each group and provide some color where appropriate. First, aerospace. Aerospace revenue of $2.2 billion was $450 million, or 22.7% ahead of the year ago period. This is attributable in large part to the delivery of seven G500 in the quarter and a solid increase in service revenue. The moderately lower operating earnings were related to the mix shift at Gulfstream from the delivery of the G500. These planes carry the burden of the test program and retrofits as we previously advised. Margins on the aircraft will improve markedly through the year. At year-end, we had indicated that aerospace margins for the first two quarters would be in the mid 14% range, up somewhat from the 14.1% rate in the final period of 2018. At 14.6%, the margin was fractionally better than that indication. Excluding the adverse impact on margins from pre-owned sales, margins would have been about 40 basis points better. Based on our delivery profile and cost improvement, we continue to expect overall margins to improve particularly so in the second half of the year. On the order front, activity in the quarter was very good. The book-to-bill at aerospace was 1.4:1 dollar denominated. The Gulfstream book-to-bill was even better. We grew the backlog for the G650 and also expanded the G500 and 600 backlog. For the 12 trailing months, aerospace book-to-bill was about 1.1 to 1. You can see more information on the quarter's deliveries and orders in exhibit J at the press release. We anticipate the G600 will be certified late June, but timing is difficult to predict given the FAA rigorous review process. Nonetheless, we expect certification of the 600 this quarter or early next deliveries will remain on track for the second half. While the pacing items for deliveries on the 500 and 600 is our ability to deliver nacelle, this is becoming less of an issue as you can discern from deliveries of the G500 in the fourth quarter and the last quarter. Nacelle costs are increasingly under control and we are producing very good quality. We expect all schedule issues to be behind us by mid-year. So forgive me this commercial plug, but earlier this month the G650 shattered a record for speed and range demonstrating its unrivaled performance. The aircraft flew 8,379 nautical miles from Singapore to Tucson in 15 hours and 23 minutes, averaging Mach 0.85, beating the record set just a few weeks earlier by the competitor's aircraft by 44 minutes. It is also interesting that the G650 traveled during that flight approximately 227 nautical miles further than the competitor's aircraft in considerably less time. This is to our knowledge the longest distance ever flown by any business aviation aircraft. This is of a particular interest to customers who think that the range and speed at that range is of vital importance. Next combat. Combat revenue of $1.6 billion was 13.6% above the year ago quarter. On the other hand, operating earnings declined $18 million with an operating margin of 12.6%. Mix was a large factor behind the results. There was strong growth in the Abrams program and a ramp up of mobile protective firepower and other new program. Stryker volumes were down, but we ascribe that to timing. Munitions also delivered growth. We also took a one-time charge in the quarter related to the disposition of a legal dispute over the closeout of a lease one of our former European operating site. Absent that one-time item, earnings for this segment would have been up year-over-year. The diplomatic issues that have slowed production on the international vehicle program in Canada are in the process of being resolved. Once resolved between the two countries, we will see a reduction in operating working capital and the corresponding increase in cash received. Backlog for this segment is lumpy, with the fourth quarter traditionally seeing the highest order activity in the first quarter the slowest this year was no exception. The $2.2 billion in orders received in Q4 followed by the approximately $1.2 billion in orders received this quarter gives us good line of sight for our production planning and continuous improvement methodology. Of note, Stryker backlog grew in the first quarter and the Army added funding to the SEP v4, the next generation of the Abrams Main Battle Tank. Stryker is a very flexible platform and the Army continues to find additional systems and weapons that we are integrating on to the vehicle. Integration of new capabilities onto our vehicles leverages our investments. Our intimate knowledge of the platform ensures that the Army receives its programs reliably and affordably. We also continue to see opportunities to expand the Ordnance and Tactical munitions businesses as the Army refreshes its ordinance and ammo stockpiles. We continue to have significant international opportunities throughout NATO and Eastern Europe, as well as the Pacific region. Next, Marine Systems. Marine revenues of $2.1 billion was up slightly and operating earnings of $118 million were down $4 million against the year ago quarter. Operating margins were 8.7% with our guidance for the year at 8.5%. We are modestly ahead of target. We have delivered the 17th ship of the Virginia-class program and have another 11 in various stages of construction. With respect to Columbia, we are 97% complete with the detailed design and nearly 43% complete with the construction design drawn. We will be at 83% complete at the start of construction, far in excess of historical design completion metrics for any class of warships. We have begun long-lead material construction on Columbia and will begin full construction of the first ship late next year. In response to the significant increase in demand from our Navy customer across all three of our shipyards, we continue to invest in each of our yards with particular emphasis at Electric Boat to prepare for the higher production associated with Block V of the Virginia program and the new Columbia ballistic-missile submarine. As you may recall, both, Columbia and the Block V represent a significant increase in size and performance by acquiring additional manufacturing capacity and different logistics infrastructure to transport the larger modules from Quonset point to the waterfront at Groton for final assembly and test. CapEx in 2018 for Marine Systems was $243 million, more than double its depreciation for the year. For 2019, we again expect the Marine segment to command the largest share of our capital budget, about half of our entire CapEx. Suffice it to say that we are poised to support our Navy customers they seek to increase the size of their fleet. Next Information Technology. For the quarter, IT generated revenue of $2.2 billion and operating earnings of $156 million with an operating margin of 7.2%. Since the numbers for the first quarter 2018 did not include CSRA, comparisons to the year-ago quarter are not meaningful. Revenue of $2.2 billion is up by over $1 billion, but is down about $200 million sequentially, over half of which is attributable to the divestiture of the call centers and the remaining the wind down of several mature programs replaced by the ramp up of new program. Margin is 7.2% is lower than Q4, due to mix, but a bit better than Q2 and Q3 of 2018. If you look at our EBITDA margin, it is 12.4% including state and local taxes in the operating results. If these taxes were carried below the line as in the case for most competitors in this segment, it would add approximately 50 basis points to our results. This places the business in the best-in-class category for its industry. The integration has gone well and is a bit ahead of the plan we put in place last year. We are taking the best of the two legacy companies and building a highly competitive enterprise with the scale and the resources to create value for our customers and our shareholders. GDIT's book-to-bill for the quarter was 1.1 to 1 and for the trailing four quarters, it is over 1 to 1. This business is growing and is positioned for growth going forward. The first quarter included some notable wins, a $490 million contract from DISA to support Pentagon network infrastructure, $125 million for helicopter training and simulation at Fort Rucker, $580 million for several classified programs and a myriad of additional wins across the portfolio. Finally for Mission Systems, revenue rose by 5.5% compared to the year ago quarter, while operating earnings of $148 million were $2 million higher than the first quarter of last year with a 50 basis point decrement in operating margins attributable solely to mix. Book-to-bill for the quarter was 1 times, following 1 to 1 book-for-Bill for this for each of the last two years. As you can see, we ended the quarter with a backlog of $5.3 billion, essentially level with the prior quarter and with the year ago quarter. Demand was broad based across many of their space and naval programs. Army Ground systems activity was particularly strong. So in my view, we're off to a good start to the year. The story in the first quarter was about revenue and backlog growth. Orders at $10.7 billion across our businesses provide us with good operational visibility. Our ongoing focus on productivity provides the opportunity to deliver very good results. As we begin this quarter, we expect our second quarter performance to be very similar to the first quarter from an EPS perspective. You may recall that we do not as practice change guidance at the end of the first quarter. It is our practice to give you a full review of our expectations at mid-year -- at mid point during the year. Suffice it to say that we are a bit ahead of the operating plan upon which our guidance was based. As always, we will work to consolidate our improvement and strive to continue to improve our results. Let me turn this over to Jason for additional commentary and then take your questions.
