Thanks, Matt. With an exciting quarter at Ligand, I have got a lot to cover given the strong performance on the royalty line, several large licensing transactions and a significant financing transaction. But before I get started I’d like to remind investors that as of January 1st we began reporting under the new ASC 606 guideline. The principal place that impacts Ligand is on the royalty revenue line, and as a result, I’ll be making a couple of comments about the comparable period for royalty revenue that provide investors with the correct comparable numbers to evaluate growth of that line item. The tables in our earnings release contain only the 2017 period numbers as reported at the time. Our 10-Q when it’s filed will have the information to describe the differences between those two and aid investors in their analysis of the business. Now let’s begin with some financial highlights from our earnings release that was issued earlier this afternoon. Total revenues for the quarter were $90 million up from $28 million a year ago, royalty revenue was in Q2 2018 was $31.4 million, which was up 43% increase compared with royalty revenue of $21.9 million in Q3 of 2017, which is the appropriate comparable period. The royalty growth largely reflected higher Promacta and Kyprolis royalties. Q2 2017 royalty revenue as reported was $14.2 million, but as I just mentioned this is not the appropriate comparable number to the Q2 2018 period. Milestone and license revenues were $51 million in Q2 2018 versus $8.2 million for the year ago period, with the increase due primarily to the recognition of the $47 million licensing payment from Wuxi Biologics that John mentioned related to amending their OmniAb platform license. Turning to material sales in Q2 2018 material sales were $7.6 million, compared with $5.6 million in Q2 2017, with a change there reflective of the timing of purchases of Captisol for use in clinical trials and commercial products. Clinical sales were higher percentage of our overall material sales in Q2 2018, and therefore, gross margins for overall material sales were slightly higher as compared with the prior year. Our material sales cost translated to an overall corporate gross margin of over 98% and as we mentioned last quarter, we expect that the gross margin for the balance of the year will be slightly below this number given that the expected mix of sales for the second half of 2018. On the expense side, R&D and G&A cash operating expenses were in line with our expectations at approximately $8.2 million combined for Q2. As disclosed previously, and as Matt mentioned, we intend to accelerate the spend related to certain R&D projects in 2018 and as a result we expect the spending to increase -- this cash spending to increase in the second half of 2018. We remain on track though for about $36 million to $38 million of cash operating expenses for the full year. Related to our GAAP net income for Q2 2018 as outlined in our earnings press release, GAAP net income for the quarter was $73.2 million or $2.99 per share. This figure includes a large non-cash item that I wanted to point out to investors. In particular, there was a significant gain of approximately $40 million related to the positive performance of Viking Therapeutics share price this quarter. Due to a change in accounting for financial instruments prescribed by ASU 2016-01, beginning in January we account – we now account for the value of our ownership in common stock such as Viking and Retrophin by marking the value of our shares to the current market price with the resulting unrealized gain or loss running through the P&L each quarter rather than at the time of the sale. Prior to this new accounting standard, the changes in value would impact the balance sheet, but not the P&L. We don’t feel that these fluctuations in value whether they are positive or negative are reflective of our core operating business. As such these gains or losses will be excluded from our adjusted earnings calculations including this excluding in this quarter the $40 million gains related to Viking. For the quarter we reported adjusted net income of $60.6 million or $2.59 per diluted share and this compares with $14.9 million or $0.67 per diluted share for the same period last year. One quick reminder for investors, our adjusted net income is reported on an after-tax basis although we continue to utilize our NOLs and tax assets, which resulted in actual cash tax rate of less than 1%. With respect to cash flow, in Q2 we generated $73.6 million in cash flow from operations, an increased from $10.4 million generated in a year ago period. On the balance sheet, in May we completed a $750 million convertible note financing. The notes bear interest of 75 basis points per year and mature in 2023. The notes have an exercise price for investors of $248.48 per share and Ligand use a portion of the proceeds to raise our effective conversion price to $315.38 per share. In connection with the offering, we also repurchased 260,000 shares of our common stock for approximately $50 million or just over $191 per share. Taking into consideration, the deal expenses, the share repurchase and the purchase to increase the exercise price we realized over $630 million of net proceeds and we finished this quarter with over $956 million of cash, cash equivalents and short-term investment on the balance sheet. In addition, we have $72 million of Viking stock and warrants that we hold on the balance sheet. Together with our cash flow from operations of well over $100 million per year, we intend to use the proceeds from the recent convertible offering to execute our strategic agenda as outlined by John focused on identifying acquisitions across our areas of interest including platform technology, acquisitions, broken biotech acquisition and acquisitions of economic rights to development and commercial stage assets. Investors should note that our outstanding 2019 convertible notes are maturing in August of 2019. However, investors may have seen that $50 million of bonds were submitted for conversion on July 27th in addition to the $21.8 million that were submitted earlier this year. As we expected at the time of the new convertible issue we continue to expect that currently Ligand stock prices folders of 2019 convertible bond will voluntarily convert their bonds over the coming months. Turning now to guidance. As outlined in today's press release, we are updating our recently disclosed full year 2018 financial guidance. Royalty milestone performance exceeded our expectations as the quarter closed out and a large order for material sales was realized earlier in the year than expected. The royalty and milestone performance will translate to a benefit for the full year. Therefore, we are -- for the year we are now -- we now expect $120 million of royalty revenue, which is up from $160 million -- $116 previously, about $23 million of capital sales which is unchanged from our prior guidance and about $89 million of milestones and license fees up from $87 million previously. In addition we continue to see upside potential up to an additional $8 million from milestone and license fees. These components translate to expected full year 2018 revenues of $232 million, up from $226 million previously, with upside from milestones and license fees, and expected adjusted earnings per diluted share of $6.30, which is up from our prior guidance of $6.15 per diluted share. With this updated guidance we are implying about $86 million in revenue for the remainder of the year. We expect royalties, milestones and material sales all to be weighted more heavily to Q4 relative to Q3 with earnings following the same pattern. As a reminder to investors as a result of ASC 606 our tiered royalty structures -- our royalty revenue recognition pattern will be changed such that we now expect royalty revenue increase in each successive quarter throughout the year with Q1 being the lowest quarter and Q4 being the highest quarter each year. Lastly, please recall that our adjusted diluted EPS guidance excludes stock-based compensation expense, non-cash debt related costs, transaction-related expenses and amortization, changes in contingent liabilities and CVRs, non-cash unrealized gains and losses associated with our investment in Viking Therapeutics, mark-to-market adjustments for amounts owed to licensors, the excess convert shares covered by the bond hedge and certain one-time non-recurring items. With that, I'll turn the call back over to the Operator and open it up for questions. Operator?
