Thanks Adam and thank all of you for taking the time to participate in today's call. We set a record for total sales during the quarter, surpassing the previous high level set during the first quarter of 2015. The strong work by our enlarged sales team has nearly doubled our sales since 2012. So before I update you on the status of our investment and our investment [ph] plan, I would like to review the bottom line and top line results for the first quarter of 2017. We reported the 11th consecutive quarter of positive net operating income; we reported net income of $584,000 or $0.12 per diluted share for the first quarter, compared to $452,000 or $0.11 per diluted share for the first quarter of 2016. The 29% higher earnings in the current period, were somewhat diluted by having more shares outstanding in the current period, as a result of share issued during two equity raises during 2016. We still have less than 5 million shares outstanding today, 4.848 million shares to be more precise. Total sales during the quarter were up 19% in comparison to the first quarter of 2016. Total sales for the 12 month period ended March 31, 2017 were $10.1 million. Sales of First Defense, our lead product have increased during 22 of the past 26 quarters, in comparison to the respective periods of the prior years. The prolonged period of order backlog, which began in early 2015 and extended to the middle of 2016, disrupted our normal shipping patterns. It is important to keep this in mind as we compare 2017 results to 2016. When we were short on inventory during the first quarter of 2016, we prioritized shipments to our domestic customers and could not allocate enough product to international markets. With our production capacity now increased by 100%, we fully met international demand during the first quarter of 2017. This largely explains the 133% increase in international sales of First Defense quarter-over-quarter. During the second quarter of 2016, we overflowed our distribution chain with product as we came out of backlog and filled nearly all our outstanding orders. This will make the comparison of the second quarter of 2017 to the second quarter of 2016 difficult. On the other hand with distributor inventory reset as of the third quarter of 2016, sales during the third and fourth quarters of 2016 were down in comparison to the same periods in 2015. This should lead to more favorable variances as we compare the second half of 2017 to the second half of 2016. We just need to work through these inevitably bumpy period-to-period comparisons until the impact of disrupted order pattern caused by the backlog is no longer in our prior year comparison. I believe that comparing 12 months period will be a good way to see through this quarter-to-quarter variability Market conditions in the dairy and beef industries, including milk prices and prices for calves weakened during 2016 in comparison to 2015, but milk prices have made a modest improvement going into 2017. The average Class III milk price declined to $14.87 per 100 pounds during 2016, from $15.80 during 2015. But it did improve by almost 11% to $16.49 during the first quarter of 2017. Our objective is to bring the most effective technology to market. Our competitors, companies like Boehringer Ingelheim, Elanco, Merck and Zoetis maybe bigger than we are but they do not offer the kind of product that we do. Getting market share from this existing comparative products provide a great opportunity for growth for us. CALF-GUARD from Zoetis is the market share leader but this product does not have an E-Coli claim and puts the calf through vaccination stress and can be inactivated by colostrum ,which is why it is recommended with whole colostrum, when administering CALF-GUARD. We provide calves immediate immunity that can be administered with colostrum as soon after birth as possible. We know that is standard practice for good calf health. The market share of Bovine Ecolizer from Elanco is relatively small compared to ours and CALF-GUARD's, but we are still aggressively displacing that product by reminding customers about the importance of our coronavirus claim, which their product does not have and by discussing new data from our labs it shows that does of First Defense contains about 28 times more E-Coli antibody which will provide calves more protection. We see that the total market is growing. Our message is conducive to gaining market share from these competitors, while also continuing to grow the pie by establishing new users of scours prevention. Very importantly the anticipated addition of a Rotavirus claim to our product line later this year would allow us not only to compete more effectively against these products but also against vaccines given to the mother cow to increase the quality of the colostrum that she produces for the newborn. We intent to market this product under the trade name, First Defense Tri-Shield. We also anticipate establishing new FCA [ph] claims for our bivalent gel tube formulation of First Defense technology. We will continue to offer this product format after Tri-Shield is available to the market. With increased production capacity in place, we have begun to engage additional distributor partnerships to bring First Defense into new international territories. So we like the calf scours market, we believe that the disease costs the dairy industry - dairy and beef industries about $740 million per year, that's a good sized market. But the mastitis market is even bigger. Mastitis costs the dairy industry about $2 billion per year, which is the single largest cause of economic harm to the industry. Presently mastitis is treated with traditional antibiotic products and treatment is generally reserved for clinical infections when the cow produces non-saleable milk. Subject to FDA approval, we expect to enter the - into the mastitis market with our Mast Out product. Our ground breaking product innovation is unlike all other antibiotic treatments on the market today. Our goal is to revolutionize the way mastitis is treated by making the treatment of sub clinical infections economically feasible by not requiring a milk discard or a meat withhold during or for a period of time after treatment. No other product can offer this value preposition. Nisin the active ingredient in Mast Out is a bacteriocin that is now used in human medicines with not contribute to the growing concern that the wide spread use of antibiotics encourages the growth of antibiotic resistant bacteria or super bugs. As many of you know we initiated construction of our $20 million pharmaceutical facility to produce Nisin, the active ingredient in Mast Out during the third quarter of 2016. As of March 31, 2017 we have invested about $6.5 million in this project, leaving about $13.5 million to go. To finance this we had approximately $7.2 million in cash and investments on hand as of March 31, 2017 and we have access to up to $7 million in available bank debt. The spending on this project comprised both of the construction activity and equipment purchases, is heavily weighted through September 30, 2017. I encouraged you to take a look at the What's New page on our website at www.immucell.com to view progress photos of the construction. We will continue to provide periodic updates there. The tangible, visual progress is very exciting. Construction of the building shell is now substantially complete. We have made significant progress on the interior fit out of the building, which is where most of the work is focused today. To maintain the timeline for anticipated FDA approval in 2019, we are working to complete construction by the fourth quarter of 2017 and complete the installation and qualification of equipment by the first quarter of 2018 followed by process validation and the subsequent regulatory filings. We expect that two submission of the regulatory package covering the manufacturing objectives will be required, each of which will be subject to a six month review by the FDA. With all that said, let's have the operator open up the lines for your questions. Thank you very much.
