Thank you, Rob and good afternoon. I will provide you with the review of the first quarter results, along with a brief review of the key financial metrics. Let’s start with sales. Our sales in the first quarter of 2015 were $13.9 million, an increase of 7.1% compared to the first quarter of 2014. Domestic sales represented 85.2% of our total in the first quarter and increased $800,000, or 6.6%, compared to the first quarter of last year. International sales represented 14.8% of our total or $2.1 million and increased 7.2% over the first quarter last year. Our overall domestic concentrate business revenue increased 6.1%, compared to the first quarter last year and included amortization of deferred license revenue of a $0.5 million. Increases in sales of our CitraPure product line was the primary driver behind increased sales volumes in the first quarter of 2015, compared to last year. Our gross profit in the first quarter, gross profit was $2.3 million, an increase of 37.6% over the first quarter last year. Gross profit margins increased by 3.7 percentage points to 16.7%. Gross profit increased largely due to higher sales compared to the first quarter last year and was favorably impacted by recognition of the deferred license revenue under the Baxter agreement. Selling, general and administrative expense for the first quarter was $5.3 million, compared to $4.1 million in the first quarter last year. Non-cash equity compensation was $3.3 million in the first quarter 2015, compared to $2.2 million in the first quarter last year, which accounted for majority of the increase in SG&A costs. Increased costs for personnel, marketing and intellectual property expenses related to preparation of our anticipated drug product launches also increased approximately 200,000, compared to first quarter last year. On research and product development, R&D decreased to $800,000 in the first quarter, compared to $4.6 million in the first quarter of last year. Future R&D spending in 2015 is expected to be primarily related to other Triferic indications. Net loss for the quarter was $3.7 million or $0.07 per share, compared to $7.8 million or $0.20 per share in the first quarter last year. This reduction was primarily due to the conclusion of our work around obtaining FDA approval for Triferic. The $0.07 loss per share for the first quarter was reduced in half compared to the fourth quarter 2014 loss of $0.14 per share. The $2.7 million reduction was largely due to the elimination of interest expense, $1.5 million and reduced R&D costs, $900,000 which together aggregated $2.4 million of the $2.7 million reduction of loss. On capital resources and liquidity, we have adequate capital resources and substantial liquidity to commercially launch our drugs and pursue our business strategies. As of March 31st, we had $94 million in current assets and net working capital of $83.7 million. We had $83.3 million in cash and investments, with $63.3 million in cash at the end of March. We have no debt. In the first quarter of 2015, we incurred $800,000 in research and product development costs and we increased our inventory by $1.3 million. We are using contract manufacturing organizations to produce our drugs. Capital expenditures on our current facilities are not expected to materially exceed depreciation expense. Future R&D spending on Triferic technology is expected to include a clinical study in pediatric patients as well as some work in TPN and PD indication. Costs are expected to be minor relative to our cash resources. Cash investments for our drug product launches will be primarily related to working capital for inventory and accounts receivable. We expect cash flow from operations to be positive following the launch of our drug products in 2015. With that, I'll now turn the call back to our operator, Amanda for some Q&A.
