Thank you, Doug. As Doug mentioned in his opening remarks, total revenues for the fourth quarter of 2013 were $50.2 million, compared to $53.9 million in the fourth quarter of 2012. Global infectious disease revenues were $39 million in the fourth quarter as compared to revenues of $44.3 million in the prior year. Influenza product revenue was $20.9 million as compared to $26.3 million in the fourth quarter of last year. The decrease was driven by a more normalized influenza and respiratory disease season in 2013, as compared to an earlier and more severe season occurring in the prior year. Sofia influenza revenue showed strong demand at 6.4 million a 103% increase over last year. Also contributing to growth in the category was a 48% increase in total RSV sales which also benefited from new sales under Sofia instrument. Strep A revenue was relatively constant to the fourth quarter of last year. Revenues for the Women’s Health category were $8.0 million in the quarter as compared to $7 million for the same period last year. This increase was due to growth in pregnancy product revenue of approximately 24%, catching up on the timing of orders from the previous quarter. [Indiscernible] product revenues grew 10% in the quarter, our gastrointestinal product category revenues were $1.9 million in the quarter compared to $1.5 million in the fourth quarter of 2012 mostly driven by increased AmpliVue C Diff revenue in the quarter. Gross margin in the fourth quarter was 63% as compared to 67% in 2012. The decrease in gross margin was primarily driven by the change in product mix, associated with higher influenza sales in the fourth quarter of the prior year. Also negatively impacting the margin versus last year is an incremental depreciation incurred from the placement of additional Sofia instruments as well as increased costs associated with quality improvement initiatives. In the fourth quarter our operating expenses were $31.4 million versus $22.2 million last year. In the quarter we incurred a couple one-time expenses. First as we discussed in last quarter’s earnings call, we completed the move of our manufacturing operations from Santa Clara, California to Athens, Ohio. Our first class research and development and molecular manufacturing facility. We recorded a facility restructuring charge of $1,300,000 relating to this move in the quarter. The majority of the charges relate to lease termination and other relocation class, starting in 2014 we will be realizing a cost savings of approximately $2 million associated with this move as we realized lower facility in human resource costs. Approximately $1 million of the savings will apply to cost of sales the other $1 million will be cost savings in general and administrative expenses. Second, the company recorded in the quarter an additional expense of 1.8 million relating to the amendment of performance based stock awards earned in 2013. Research and development cost in the fourth quarter were 11.3 million compared to 7.3 million last year. In the fourth quarter there was no benefit realized from the Life Technologies collaboration agreement, whereas in the fourth quarter of 2012 the research and development cost benefit was $1.7 million. Also impacting the spend this quarter was a continued investment in our molecular platforms including Savannah as well as costs associated with the two acquisitions we consummated earlier this year BioHelix and AnDiaTec. In the quarter the two acquisitions added an incremental $1.7 million in expense as we realized higher clinical study costs associated with the AmpliVue platform. As we have previously communicated in 2014 we believe our research and development spend will be in the range of $30 million to $32 million as we continue to support our Immunoassay and molecular product development initiatives. Sales and marketing expenses increased in the current quarter to $9.7 million, the increase is primarily due to the continued investment in our commercial organization. We have added approximately 25 sales reps since this time last year, and we believe we currently have a fully operational commercial organization as Doug mentioned to support our existing and future product launches. Expenses for G&A were $6.9 million in the quarter compared to $4.8 million for the same period last year. In the quarter we realized expenses of approximately $400,000 associated with the medical device excise tax and approximately $300,000 associated with our ERP upgrade of our Athens, Ohio facility. We now have successfully completed our company wide ERP upgrade project. Also impacting the quarter was an increased incentive compensation expense of which approximately $900,000 related to the previously mentioned amended performance based stock awards. In the fourth quarter our provision for income taxes was a benefit of approximately $1,200,000. This benefit was mostly the result of realizing a significant portion of the full year research and development credit in the fourth quarter. Stock based compensation expense for the three months was $3.3 million; an amortization of intangibles was $4.2 million. In the quarter amortization associated with the Alere Royalty arrangement was $1.9 million and was recorded in cost of sales. As a reminder the amortization discontinues in February 2015. Net income for the fourth quarter was $1.1 million or GAAP EPS of $0.03 per diluted share as compared to net income of $8.7 million or $0.26 per diluted share for the fourth quarter of 2012. On a non-GAAP basis excluding the facility restructuring charge amortization of intangibles and stock compensation expense, net income for the fourth quarter of 2013 was $7 million or $0.20 per diluted share compared to net income of $12.5 million or $0.37 per diluted share last year. For the full year ended December 31, 2013 revenues were $175.4 million compared to $155.7 million for the full year of 2012, an increase of 13%. Infectious disease revenues grew 16% for the year to $128.5 million versus $111 million in 2012, driven by the growth from influenza products associated with a robust influenza season during the first quarter of 2013. For the year we generated $62.6 million in combined QuickVue and Sofia influenza sales versus $45.2 million in 2012. Adding to this growth was a 33% increase in total RSV sales. Strep revenue for the year was down 12% a result of a lower disease incidence realized in the first half of this year versus last year. Our DHI infectious disease revenues grew by 2%, as a 9% increase in general virology was partially offset by a decrease in our respiratory viral panel business. The women’s health segment was $32.7 million this year equal to last year. In 2013 our gastrointestinal segment grew 7% to 6.8 million as compared to $6.3 last year mostly the result of growth in our AmpliVue C. difficile product line. Gross margin for the year expanded by approximately 1 percentage point over last year to 62%, this improvement is mostly driven by the increased influenza sales versus last year and the positive impact on product mix. Research and development expense for the year was $34.2 million in line with our earlier testaments. The increase versus last year was due to the increase investment in our molecular platform mostly in support of our Savanna project. Sales and marketing expenses for 2013 were also in line with our internal estimate at $33.8 million, a 12% increase over last year. Since the first half of 2012, we have increased the size of our sales and marketing team in order to support our existing and new product growth and to support our distribution partners. General and administrative expenses for 2013 were $26.3 million as compared to $20.6 million last year. The medical device excise tax increased our year-over-year spend by $1.9 million. For the year, we incurred $1.1 million for our ERP implementation project and approximately $1.8 million for the full year and restructuring relating to the relocation of our Santa Clara manufacturing operations. For the full year, the provision for income taxes was a benefit of $4 million. In the first quarter of 2013, we realized a benefit of approximately $500,000 relating to the 2012 research and development tax credit. In the second quarter of 2013, the IRS notified us that its review of tax periods ranging from 2008 through 2010 resulted in no proposed changes. As a result, we released tax reserves of approximately $3.5 million. For 2014, we estimate our effective tax rate to be in the range of 34% to 36% excluding the impact of any non-discrete tax issues and without consideration for the 2014, research and development tax credit which has not yet been approved by Congress. Net income for the full year was $7.4 million or GAAP EPS of $0.21 per diluted share as compared to net income of $5 million or $0.15 per diluted share last year. On a non-GAAP basis excluding amortization of intangibles, stock compensation expense, and certain non-reoccurring items net income for the year was $21.3 million or $0.61 per diluted share compared to net income of $19.1 million or $0.56 per diluted share for the full year 2012. For the 12 months ended 2013, the company generated approximately $26 million in cash from operating activities, spent approximately $20.8 million in capital expenditures and approximately $13 million in investing activities to acquire both BioHelix and AnDiaTec. In the year, we realized an increase of approximately $11.5 million on working capital mostly driven by an increase in inventory to support our Sofia and molecular platforms as well as building inventory of ahead of our Santa Clara relocation. In 2014, we do not believe inventory will be a continued use of cash. As of December 31st, Quidel had $9.4 million on cash, restricted cash and cash equivalents. Currently, we have no outstanding borrowings under our senior credit facility. And with that, we conclude our formal comments for today. Operator, we now are ready to open the call for questions.
