Ladies and gentlemen, thank you for standing by.
And welcome to the Gilead Sciences second quarter 2009 earnings conference call.
I will be your coordinator today.
(Operator Instructions).
As a reminder, this conference call is being recorded today, July 21, 2009.
I would now like to turn the call over to Susan Hubbard, Vice President of Investor Relations.
Please proceed.
Susan Hubbard - VP, IR
Thank you, Melanie, and good afternoon, everyone.
Welcome to Gilead's second quarter 2009 earnings conference call.
We're pleased you could join us today.
We issued a press release this afternoon providing results for the second quarter ended June 30, 2009.
This press release is available on our web site at www.gilead.com.
We've also posted slides that outline the topics discussed on this call.
Joining me today are John Martin, Chairman and Chief Executive Officer; John Milligan, President and Chief Operating Officer; Kevin Young, Executive Vice President of Commercial Operations; Norbert Bischofberger, Executive Vice President of Research and Development and Chief Scientific Officer; and Robin Washington, Senior Vice President and Chief Financial Officer.
We'll keep prepared comments brief to allow more time for Q&A.
I would first like to remind you we'll be making statements relating to future events, expectations, trends, objectives and financial results that constitute forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995.
These statements are based on certain assumptions and are subject to a number of risks and uncertainties that could cause our actual results to differ materially from those expressed in any forward-looking statements.
I refer you to our Form 10-K for the year ended December 31, 2008, Form 10-Q for the first quarter of 2009, subsequent press releases and other publicly filed SEC disclosure documents for a detailed description of the risk factors affecting our business.
In addition, please note that we undertake no obligation to update or revise these forward-looking statements.
We will be making certain references to financial measures that are on a non-GAAP basis.
We provide a reconciliation between non -- and non-GAAP numbers on our web site.
I'll now turn the call over to John Martin.
John Martin - Chairman, CEO
Good afternoon, everyone, and thank you for joining us today.
Product revenues in non-GAAP earnings for the second quarter reached record highs of $1.57 billion and $0.69 respectively.
Importantly, we have generated more than 621 -- $620 million in operating cash flow.
As Kevin will describe later in the call, our anti-viral franchise continued its momentum in gaining share across all our commercial markets reaching a record revenue of $1.41 billion.
We're very pleased that Atripla received reimbursement in France, allowing us to launch the product in May.
France represents the largest market in the European union with nearly 140,000 HIV infected patients.
And will be yet another contributor to the continued growth of this franchise.
The second quarter was also very busy on the organizational front as we closed the CV Therapeutics acquisition and made several management decisions to integrate the Palo Alto employees into Gilead.
First, we realigned the reporting structure of the combined cardiovascular organization under Norbert Bischofberger's leadership.
Luiz Belardinelli, from CV Therapeutics has been named to Senior Vice President of Cardiovascular Therapies, overseeing our cardiovascular R&D efforts and reporting to Norbert.
Lou Lange has assumed a part-time advisory role within the organization, providing his experience, expertise and knowledge about our cardiovascular products and programs.
We believe these changes will best position us for continued growth and productivity in this therapeutic category.
In addition, we moved medical affairs to report to Greg Alton, who also is responsible for our government affairs, public affairs, international access operations, and legal affairs functions.
This structure will allow us to continue to have a positive influence on health policy and deliver scientific and medical information to benefit the healthcare communities we serve.
In conjunction with Greg's broader role, Brett Fletcher was promoted to General Counsel.
Brett most recently served as Vice President, Legal Affairs, focusing primarily on legal support for corporate development, finance, research, human resources, governance, manufacturing and clinical operations.
As we enter the second half of 2009, I am confident about the strength of our organization to drive future success given the scientific and commercial progress we have achieved year-to-date.
I will now turn the call over to Norbert to discuss our research and development progress during the quarter.
Norbert Bischofberger - CSO, EVP of R&D
On the research and development front, we continue to make significant progress with our pipeline.
As we have a great deal to cover during the prepared comments portion of this call, I would like to only speak to the most notable advancements.
One of these advancements is the initiation as well as the completion of enrollment during the quarter of two important Phase II studies in HIV-infected patients.
The first study is evaluating our quad drug, the fixed dose regimen of Truvada Elvitegravir in GS9350 versus Atripla.
And the second is a head-to-head study of GS9350, our novel boosting agent versus ritonavir.
These are both 24-week primary end point studies which should be completed by year-end.
There has been significant enthusiasm from investigators surrounding these studies and we will target having the full data sets presented at a scientific conference early next year.
The Phase III study of Elvitegravir head-to-head versus with raltegravir in treatment experienced patients is now more than 60% involved and we're on target to complete enrollment in this study before the end of this year.
We continue to pursue strategies to bring forward additional and improved options for patients with HIV.
This is demonstrated by our announcement just last week with Tibotec to develop a fixed dose combination of our Truvada with their in-and-out Ti drug candidate TMC278.
If approved, this new product will become the second complete anti-retroviral treatment regimen for HIV, besides Atripla, available in a single tablet taken once daily.
We initiated co-formulation work prior to the completion of the agreement with Tibotec and have now identified and produced two formulations of the fixed dose combination.
In addition, we completed animal PK studies, and are now progressing these two formulations towards human bioequivalent studies.
Data from these studies along with supporting stability data will form the basis for our regulatory filing of the fixed dose combination sometime later next year.
The NDA filing of TMC278 itself, will be supported with data from two pivotal studies in treatment-naive patients that Tibotec currently has underway.
John Milligan will speak to the terms of our agreement with Tibotec later in the call.
In April, we presented 96-week data from both our Viread for HPV pivotal studies and we had a poster presentation of the Phase I data of GS 9450, our Caspase inhibitor in healthy volunteers at the European Association for the Study of the Liver, or EASL conference.
GS 9450 has now progressed into a Phase IIb study which is evaluating two doses of the drug versus placebo in 240 HCV infected patients with efficacy assessed by histology.
We're also continuing to evaluate GS 9450 as a potential treatment for NASH in a Phase IIa study.
At the American Thoracic Society conference in San Diego in May, there were five presentations on Letairis, including the first presentation of data from the ARIES-3 study, which is evaluating Letairis therapy in patients with pulmonary hypertension of diverse ideologies.
At the American Society for Hypertension conference in San Francisco also in May, we presented the data in the late-breaker session from study 311, the first darusentan Phase III study in patients with resistant hypertension.
We've also completed enrollment in study 312, which is the second pivotal study and we'll have data by year end.
The EU marketing application for Regadenoson, an investigational pharmacological stress agent for radionuclide myocardial perfusion imaging was filed and validated during the quarter, and is currently under review.
We also received a positive opinion for conditional approval from the European Committee for Medicinal Products for Human Use, the Scientific Committee of the European Medicines Agency on aztreonam for inhalation for cystic fibrosis.
And just yesterday, we were notified by the regulatory agency in Canada, that the product has received a notice of compliance for recommendation for approval in that territory as well.
We anticipate both European commission and Canadian approval of aztreonam, which is trade name [Casedam] in the second half of 2009.
And just today, important data from a landmark five year trial, developing anti-retroviral therapy for Africa, or DART were presented during the late breaker session of the Fifth International AIDS Society conference in Capetown, South Africa.
The DART trial evaluated more than 3300 patients with advanced HIV.
disease in Uganda and Zimbabwe.
In this study patients received anti-retroviral therapy and were randomized to clinical and laboratory monitoring or to clinical monitoring only, with 74% of the patients receiving a Viread containing regimen.
Without treatment, the researchers estimated that more than 90% of the DART patients would have died within these five years.
But after five years of receiving combination HIV therapy, 88% of participants were still alive.
This is one of the best survival rates observed in an HIV treatment program or study conducted in Africa.
And importantly, Viread was well tolerated during the five years of the study; side effects were similar in patients who received routine laboratory monitoring than those who did not.
The DART researchers concluded that laboratory monitoring, including kidney monitoring tests for Viread, may not be necessary in resources-limited settings when using the product as part of a first line HIV treatment regimen.
The DART study provides important additional clinical evidence that HIV treatment utilizing Viread helps to extend life in developing countries where the AIDS epidemic has hit the hardest.
And we congratulate the DART team on their success in this important research effort.
And finally, as John discussed, as we worked through the integration of CV Therapeutics, it became clear that there were areas of overlap between the Colorado and the Palo Alto organizations, and that the cardiovascular research and development activities would be most productively managed at one site.
Consequently, we have decided to close our Colorado facility.
We chose the Palo Alto site due to its proximity to our headquarters here in Foster City.
We also recently completed our first comprehensive review of our now considerable combined cardiovascular portfolio and we're in the process of focusing our activities on the most promising projects and programs.
And with that, I would like to turn it over the call to Robin.
Robin Washington - SVP, CFO
Thanks, Norbert.
I'm very pleased to provide you with Gilead's financial performance for the second quarter of 2009.
Total revenues which include product sales and royalty, contract and other revenues were $1.65 billion, a 29% increase year-over-year.
Net income was $571 million, or $0.61 per share.
Non-GAAP net income for the second quarter, which excludes the impact of after tax acquisition-related expenses, restructuring expenses and stock-based compensation expenses, was $649 million, or $0.69 per share, representing a year-over-year increase in net income and EPS of 38% and 43% respectively.
Operating cash flows was $623 million.
Product sales were $1.57 billion.
Antiviral product sales grew to $1.41 billion, up 26% year-over-year and 5% sequentially.
Truvada sales contributed $608 million to our antiviral product sales, up 18% year-over-year and 3% sequentially, due primarily to sales volume growth in both the US and Europe.
Atripla contributed $569 million to our antiviral product sales.
Atripla sales increased 60% year-over-year and 12% sequentially, resulting from the continued uptake of this product in the US and Europe, including the launch of Atripla in France this quarter.
The efavirenz portion of Atripla which is purchased from BMS at its estimated market price and reflected in cost of goods sold was approximately $208 million.
Viread sales were $159 million, representing a year-over-year increase of 5%, and a sequential decrease of 1%.
Hepsera generated sales of $67 million, a decrease of 26% year-over-year and 8% sequentially.
Letairis were $44 million, an increase of 79% year-over-year and 11% sequentially, driven primarily by sales volume growth in the US.
Finally, Ranexa sales were $36 million from April 15, 2009, the acquisition date of CV Therapeutics, to the end of the second quarter.
Foreign currency exchange had a net unfavorable impact of $50 million on revenues, when compared to the same period last year.
On a sequential basis, foreign currency exchange did not have a significant impact on revenues.
Before leaving product sales, I wanted to comment on US inventory levels.
US wholesalers increased their inventory levels for Atripla and Truvada during the quarter.
Given that retail demand was consistent with both prescription demand and revenue growth during the quarter, there is the possibility that US wholesalers may decrease their inventory levels for Atripla and Truvada in the second half of 2009.
Our royalty, contract and other revenues for the second quarter were $79 million, an increase of 29% year-over-year and a decrease of 5% sequentially.
The year-over-year increase was primarily driven by increased Tamiflu sales related to pandemic planning initiatives worldwide.
The sequential decrease was primarily due to the recognition of $24 million of deferred revenues in the first quarter related to one of our collaborations.
Royalties received from Roche and recognized in our revenues in the second quarter were $52 million.
These royalties, which are paid one quarter in arrears, reflect a royalty rate of approximately 15% as applied to Roche's net sales of Tamiflu during its first quarter of 2009.
Roche is scheduled to report their second quarter 2009 earnings this Thursday, July 23rd.
It is important to note that the following discussion of all margin and expense-related items are on a non-GAAP basis, which excludes the effect of acquisition, restructuring and stock-based compensation expenses.
Product gross margin was 76.9% compared to 78.8% for the same quarter of last year, and 77.6% for the first quarter of 2009.
Both the year-over-year and sequential decreases were due primarily to the high proportion of Atripla sales which include the efavirenz component at zero gross margin.
Operating margin was 52.4% compared to 51.1% for the same quarter last year, and 55.5% sequentially.
Our sequential operating margins were negatively impacted by the operating results from the CV Therapeutics acquisition and lower product gross margins.
R&D expenses were $206 million, an increase of 28% on a year-over-year basis, and an increase of 20% sequentially.
Both the year-over-year and sequential increases were due primarily to increased clinical study activity and compensation and benefit expenses as a result of the acquisition.
SG&A expenses were $213 million, an increase of 6% year-over-year, due primarily to higher head count and expenses from the acquisition.
On a sequential basis, SG&A expenses increased 16%, due primarily to increased promotional expenses, higher head count and expenses associated with the acquisition.
Excluding these expenses, SG&A was essentially flat on a sequential basis.
Other income and expense reflected a net expense of $6 million for the second quarter, compared to a net expense of $2 million for the same quarter last year, and a net expense of $13 million for the first quarter of 2009.
Our year-over-year and sequential other income and expense was favorably impacted by the lower hedging expenses in the second quarter of 2009, which was partially offset by lower year-over-year interest income due to lower investment yields.
Our effective tax rate for the second quarter was 24.7%, compared to 28.3% for the same quarter last year, and 26.3% for the first quarter of 2009.
The year-over-year and sequential decreases were driven primarily by the resolution of certain audits with tax authorities, and increased earnings in lower tax jurisdictions.
Now, I would like to highlight some of the purchase accounting and restructuring impacts of the acquisition.
$951 million of the $1.4 billion acquisition price was allocated to intangible assets related to CV Therapeutics' marketed products, Ranexa and Lexiscan.
And we capitalized $180 million of in process research and development intangible assets in accordance with the guidance of the newly effective FAS 141R.
In addition to the organizational changes that John mentioned, we've developed and communicated a restructuring plan to realize head count and facility synergies between Gilead and CV Therapeutics, and to realign our cardiovascular operations.
We have identified significant opportunities in SG&A as a result of the acquisition that more than offset the incremental sales and marketing investments we intend to make to execute on the commercial Ranexa strategy that Kevin will speak to.
Also, as previously mentioned, we finalized plans to close our Colorado-based cardiovascular research facility by the end of this year and consolidate it with our Palo Alto facility.
We believe these changes will allow us to more efficiently and effectively support the ongoing initiatives of the combined company.
In accordance with FAS 146, we account for restructuring expenses as the liabilities are incurred and recorded $18 million of after tax restructuring expenses primarily impacting SG&A in the second quarter.
We expect to incur additional restructuring expenses through 2010 as we complete this plan.
Our balance sheet continues to be strong with cash, cash equivalents and marketable securities of $2.9 billion as of June 30, 2009.
As mentioned in the second quarter, we generated $623 million in operating cash flow.
We utilized $1.25 billion in net cash to fund the acquisition, including $400 million that we borrowed under our credit facility.
We also utilized $305 million in cash to extinguish substantially all of the convertible senior notes we assumed in the acquisition.
We repurchase 5.3 million shares of our common stock at a cost of $238 million.
As of June 30, 2009, we had approximately $530 million remaining for share repurchases under the $3 billion share repurchase program scheduled to expire at the end of 2010.
We continue with our commitment to review opportunities to leverage our cash position to expand our business, as well as to return value to our shareholders.
Now, turning to guidance for the year, which is available on our corporate web site.
All guidance metrics we'll discuss today include the operations acquired from CV Therapeutics.
Also, our non-GAAP product gross margin and operating expenses guidance exclude the impact of acquisition, restructuring and stock-based compensation expenses where applicable.
Based on the momentum of our anti-viral franchise, and the addition of Ranexa to our cardiovascular revenue stream, we're increasing net product revenue guidance for the full year 2009 from $5.9 billion to $6 billion, to $6.1 billion to $6.2 billion, which reflects a 20% to 22% increase over 2008 net product revenues.
Factors that may have an impact on our business include, but are not limited to the potential for continued volatility and foreign currency exchange rates, US and International government pricing pressures, and changes in the financial health in our practices of our business partners and customers.
Other factors that were considered in updating our product revenue guidance include the potential for a decrease in inventory levels of Atripla and Truvada in the US following the increase in the second quarter, and the impact of a competitive generic entry of Viread into the Brazilian market.
Our non-GAAP product growth market guidance for 2009 remains unchanged and is a range of 76% to 78%.
We are increasing non-GAAP R&D expenses from a range of $800 million to $820 million, to a range of $850 million to $870 million.
This guidance now also includes a portion of the anticipated R&D expense reimbursements payable to Tibotec, for the development cost associated with TMC278 as previously announced.
We are increasing non-GAAP SG&A expenses from a range of $720 million to $740 million, to a range of $810 million to $830 million.
This is an approximately 12% increase over our previous guidance, and relates entirely to incremental integration and operational expenses resulting from the CV Therapeutics acquisition.
As previously mentioned, we have rapidly identified synergies between our two organizations which will allow us to remain focused on effective expense management across the Gilead organization.
Our effective tax rate guidance for the full-year 2009 is expected to remain in the range of 26% to 27%.
And finally, we are increasing the full-year diluted EPS impact of acquisition, restructuring and stock-based compensation expense from $0.14 to $0.16, to $0.23 to $0.26.
Additional details can be found on our corporate web site.
At this point, I would like to turn the call over to Kevin, who will discuss our commercial highlights for the quarter.
Kevin Young - EVP, Commercial Operations
I'm very pleased to discuss with you today the continued progress we have made with our commercial products during the second quarter.
The data we will be presenting is the most recent available to us for the analysis of market share in the US and Europe.
During the second quarter, US HIV revenues performed strongly led by Atripla at $398 million, up 27% year-over-year, and Truvada at $286 million, up 21% year-over-year.
In the first quarter of 2009, the number of patients being treated with anti-retroviral therapy grew by 7% on a moving annual total basis to approximately 569,000 patients.
Truvada maintained its position as the backbone of choice for antiviral therapy in the US with 203,000 patients on therapy, or 36% of all treated patients.
Atripla remained the most prescribed regimen in HIV with 188,000 patients on therapy, or 33% of all treated patients.
Atripla, together with Truvada, continue to account for approximately 86% of new patients to therapy, up from 84% last quarter.
Atripla remained the number one regimen, capturing approximately 54% of treatment-naive patients, up from 45% in the last quarter.
Additionally, we continue to see changes in prescriber behavior based on last year's changes in DHHS treatment guidelines.
Epzicom's share continued to decline, falling from 12% of naive-patients in the first quarter of 2008, to 4% in the first quarter of 2009.
We're very pleased with the performance of all of our HIV products in Europe, with sales of Atripla of $155 million, up 24% sequentially.
Since the listing of public price for Atripla on May 5th, early indicators from France are encouraging.
95% of all major HIV hospitals have already ordered Atripla and each of the top 32 HIV treating centers in Paris have become -- have begun prescribing.
In the big five countries of Europe, approximately 24% of patients receiving Atripla converted from Truvada to Estiva in the second quarter of 2009, while 35% were switches from other regimens, and 41% of patients starting treatment were naive patients.
Truvada continued to build on a solid base throughout the EU and remained the number one brand in all big five markets.
During the second quarter of 2009, Truvada contributed $288 million in revenues, up 19% from the same period in 2008.
Atripla, together with Truvada, all total Truvada, increased its share to approximately 75% of treatment naive patients.
While Kivexa's share continued to decline to 10% at the end of the second quarter 2009, down from approximately 16% in the second quarter of 2008.
Total Truvada achieved new highs in the NRTI market, outperforming Kivexa with a prescription ratio of 3.2 to 1 in April 2009, up from 2.5 to 1 in April 2008.
Comparable to the US, the big five countries of Europe continue to demonstrate robust growth.
At the end of the first quarter 2009, 277,000 patients being treated with anti-retrovirals representing a growth rate of 7% on a moving annual total basis.
Now, turning to our US hepatitis franchise.
As of April 2009, Viread achieved a 34% naive patient share in the HBV market, just 3 percentage points behind the current market leader Entecavir.
Estimated total Viread HBV prescriptions grew by 24% from the first quarter to the second quarter of 2009.
We look forward to the presentation of our 144-week data from our pivotal studies 102 and 103 being presented at the American Associations for the Study of Liver Disease conference taking place in Boston later this year.
In Europe, today, we have reimbursement approval for Viread in 16 countries.
The 2008 endorsements, within the EASL guidelines for Viread usage in both naive and lamivudine-resistant patients, and our advantageous price point relevant to Entecavir, puts it in a position to become the HBV antiviral market leader.
As of April 2009, Viread's HBV share is estimated to be 13% versus 9% at the start of the year.
In Germany, one of our first countries -- countries of launch, Viread has already achieved 22% market share and is very close to surpassing Entecavir.
In Turkey, where we established our affiliate specifically for the launch of Viread HBV, we have achieved a 19% share in just nine months post-launch.
Now, turning to our cardiovascular franchise.
We continue to make solid progress with Letairis for the treatment of PAH.
At the end of May, we received a revised label from the FDA that now requires an annual re-enrollment in the LEAP program.
This change is a positive step, bringing our risk MAP requirements for Letairis ambrisentan closer to parity.
We have also had a very positive reaction to our web-based support service called LabSync, which is designed to minimize the burden of monthly lab monitoring.
According to our latest data, as we exited the second quarter, approximately one in three patients receiving an ERA were taking Letairis.
Additionally, Letairis now captures approximately 35% ERA share of all newly diagnosed PAH patients.
And finally, to update you for the first time on Ranexa.
Prescription demand for Ranexa has been on an upward trajectory since the label revisions that occurred in November of 2008.
For the most recent quarter, total prescriptions grew by 13% sequentially.
During the second quarter, we saw stabilization in wholesale inventory levels after a sizable decrease in the first quarter.
Robin provided total US sales for Ranexa of $36 million from the CV Therapeutics acquisition date to the end of the second quarter.
It is important to highlight that the reported figure includes $3.6 million in booked tablets supplied to Menarini, our licensee for Ranexa in Europe, as part of our supply obligations that began earlier this year.
Total sales for the full second quarter, including sales made by CVT prior to our closing date, and inclusive of booked shipments were $45.5 million.
We have now shifted our Ranexa focus to operational execution, including increasing the sales force from 170 representatives, to 205 representatives.
This expansion will be completed by the beginning of the fourth quarter.
We have designed a new core list of physicians based on angina prescribing potential, as well as improved the message points used for positioning Ranexa.
We'll also be adding a 20-person field-based medical science team, and investing in CME programs, advisory boards and speaker-training programs.
We have also made the decision as of the middle of August to terminate the contract with Inventive Health for the 40 person primary care selling team.
Lastly, we've made tremendous progress on the formulary status of Ranexa.
As of the end of the second quarter, Ranexa was covered by approximately 70% of commercial private pay plan lives at tier two status.
I will now turn the call over to John Milligan for closing comments.
John Milligan - President, COO
Thank you, Kevin.
Actually, before I begin the prepared section here, I do want to make one correction.
Kevin misspoke to say there was $45.5 million in Ranexa sales.
The actual total was $41.5 million.
So I apologize for that slip up, and hope you got the correct number.
In summary for the second quarter of 2009, it was a highly productive quarter for Gilead, with significant milestones achieved at each of our four therapeutic categories.
I also could not be more pleased with all of the progress we're making on our HIV portfolio.
As Norbert discussed earlier, in addition to the advancement of our pipeline compounds, namely the quad and GS 9350, the collaboration with Tibotec for a fixed dose co-formulation of TMC278 with Truvada, continues to underscore the creative and collaborative nature that we apply to advancing medicines for patients with HIV, working to provide additional and improved options for their treatment.
Subject to regulatory approval, we'll assume the lead role in the manufacturing, registration, distribution, and commercialization of the product worldwide, excluding the developing world and Japan.
Tibotec will be responsible for the commercialization of TMC278 as a stand alone product, and will hold rights to co-promote the fixed dose combination in these territories.
The companies will also work toward an agreement to make the fixed dose combination available in the developing world.
With regard to the terms of this agreement, we will make future payments to Tibotec of up to $100 million for their development costs for TMC278.
In addition, once the product is launched, we'll book all revenues associated with the product, retaining all of the Truvada-related revenue, as well as a significant percentage of the TMC278-related revenue, which recognizes Gilead's investment in the clinical development of TMC278 and the combination product.
Putting together collaborations such as these is a complicated and time-consuming process.
I would like to commend the teams from both companies for their thoughtfulness and dedication, working together as they did to make this important new product a reality for patients.
We're disappointed with Brazil's decision to reject our patent application for Viread, and are seeking to appeal their decision, as we believe Viread represents an important innovation.
Intellectual property and patents are the assets of research-based companies, reflecting the tremendous investment made, risk taken, and value created.
We believe patent protection is necessary to ensure continued investment and innovation, and that is not an impediment to treatment access when used responsibly cut by companies such as ours.
With our now expanded cardiovascular franchise, we'll closely chart our progress with Ranexa for chronic angina, as well as Letairis and PAH.
We look forward to the data from the second pivotal study, study 312 of darusentan in resistant hypertension before the end of this year, so we can assess the potential of the compound in patients with dangerously high blood pressure.
I would like to close by thanking all of our employees for their focus and dedication during a very busy and difficult time, as well as our shareholders for your support.
We continue to strive to run an effective and efficient organization, as exemplified by the integration of CV Therapeutics into Gilead in a very cost-effective manner.
I'll now turn the call over to the operator for the Q&A session.
Operator?
Operator
(Operator Instructions).
Geoff Porges with Bernstein.
Geoff Porges - Analyst
Thanks very much for taking the questions and congratulations on a very solid quarter, particularly on the top line.
A couple of questions on the J&J agreement, or at least one question related to that.
Could you clarify the outlook for both parties to develop other combinations, John?
Can J&J do other triple combinations with, for example, tenofovir in them post 2017?
Conversely, can Gilead develop other combinations with NNRTIs, and then any chance of a protease inhibitor combination being developed by you guys as well?
Thanks.
John Milligan - President, COO
Hey, Geoff, it's John Milligan.
So the answer is that these are nonexclusive deals.
So, J&J, so Tibotec specifically, a part of J&J, has the right to co-formulate TMC278 with other products, and we'll continue to have the right to co-formulate other products with Truvada, including other NNRTIs as you talked about.
There are some limitations to what J -- what Tibotec can do with regard to other co-formulations, including our product.
I'm not at liberty to say the details of that.
But we have thoughtfully executed this contract to allow them flexibility, but also to retain the value that we've created with our Truvada franchise.
So that is mostly what I can say.
And yes, there certainly are other opportunities for us to co-formulate with protease inhibitors, including one that we might develop on our own.
Geoff Porges - Analyst
Thanks very much.
Operator
Mark Schoenebaum with Deutsche Bank.
Mark Schoenebaum - Analyst
Okay.
Thank you very much.
I have just a question -- I didn't understand what you guys said about inventories.
You said inventories built in the quarter a little bit, and that they may come down into the end of the year.
Is there any way you can help quantify what impact that had on sequential 2Q sales growth?
Robin Washington - SVP, CFO
Hi Mark, it is Robin.
Mark Schoenebaum - Analyst
Hi, Robin.
Robin Washington - SVP, CFO
We wouldn't necessarily quantify it, but to your point, they did go up for Atripla and Truvada by several days, which means absolute inventory levels went up.
And it makes sense for that to happen, given our speculation that the price increases that we announced July 1, caused some speculative buying in Q2.
So, that would be pretty consistent with trends we've seen in the past relative to inventory increases --
Mark Schoenebaum - Analyst
(inaudible).
Robin Washington - SVP, CFO
-- and activity.
Mark Schoenebaum - Analyst
That's wholesaler inventories, right?
Robin Washington - SVP, CFO
Yes, that would be wholesaler inventories.
Mark Schoenebaum - Analyst
And do you think -- are they normal now, the levels?
Then I'll stop asking follow-ups.
Kevin Young - EVP, Commercial Operations
No.
Mark, it is Kevin.
As Robin said, they did go by several days.
We've seen this historically in the past, often these large wholesalers are specking.
I do want to emphasize that the call to was very strong from an underlying demand point of view.
I think you have seen it in the IMS data, we've seen in the Wolters Kluwer data, and certainly when you look at [vacilovate] and the way we've increased our shares, I think this is a great quarter for patient demand, and should not just be seen as some form of inventory build-up.

Bret Holley - Analyst
Yes.
Hi, thanks for taking the question.
I'm just wondering about the positioning of the quad pill versus TMC278 combo.
I'm wondering in the Johnson & Johnson deal, makes it perhaps more likely you'll assess the quad pill in Phase III, versus a PI-containing regimen?
John Milligan - President, COO
Hi Bret, it is John Milligan.
As we've announced previously, we do intend to take the quad pill into two studies, one of which will be versus Atripla, the other of which will be versus a boosted protease inhibitor.
We haven't determined if it will be atazanavir, or if it will be darunavir, but it will be one of those two products going forward.
So yes, we do think there is a significant opportunity to take share away from protease-containing regimens based on obviously, positive clinical data coming out of this.
And also based on the fact that only about half of the physicians currently tend to prescribe a PI or an NNRTI so there is an opportunity for us to do that.
There is a possibility we could position it slightly differently, but at the end of the day, we wanted to provide better options for patients.
TMC278 with the collaborative with Tibotec allowed us to do that sooner rather than later, and so the time value of that plus the economics of that became very attractive to us as well.
I think we have two chances for success across a broad range of patients going forward.
And basically, we're providing another set of great options.
So, I think it really made a lot of sense for us.
Kevin Young - EVP, Commercial Operations
Bret, just to add in terms of promotional sequence, obviously when all being well when we get to the 278 fixed dose combination, that would replace Atripla in the promotional line-up, and then when the quad comes along the quad would be the lead agent that we would promote and the 278 fixed dose combination would be behind that.
Bret Holley - Analyst

Thomas Wei - Analyst
Hi.
Thanks.
I had a question on the second quarter US HIV franchise.
I understand your comment about end-user demand based on IMS data and Wolters Kluwer, and the Synovate data, but if you actually look at the reported second quarter number and calculate total tenofovir and total Truvada sales growth on a sequential basis, it doesn't look very strong, especially since you're telling us that there was an inventory increase at the wholesaler level.
Can you help us understand how we should think about this quarter?
And whether or not there were any other factors like nonretail that we might need to account for in our analysis of the sequential growth rates?
Kevin Young - EVP, Commercial Operations
Hi, Thomas.
It's Kevin.
You went straight to it.
It is the nonretail.
It is the same shape of year that we had in 2008, but it is not as deep, in terms of the way the Q2 stepped off Q1.
As you know, in Q1 of 2008, we really did have a very, very large quarter.
And therefore Q2, relative to that was much smaller.
What we saw in 2009 was a larger Q1 relative to the fourth quarter, but not as pronounced because, as you know, the ADAP programs were buying earlier, it was a sort of smoother year.
But even then, we did have a step down, as we expected in Q2.
So, that really will kind of square -- will really square away your calculations.
Operator
Geoff Meacham with JPMorgan.
Geoff Meacham - Analyst
Hey guys, congrats on a good quarter.
Hey a question for Norbert.
I'm wondering if you can walk us through the details of the clinical path forward for the Tibotec, the 278 combo.
And as a follow-up, do you guys have to conduct any studies either preclinical or early clinical before you can start a Phase III program?
Norbert Bischofberger - CSO, EVP of R&D
Hi, Geoff.
It is actually fairly simple.
TMC278, of course, has to be developed according to the normal guidelines with two Phase III studies in treatment naive patients.
And that's all being done by Tibotec.
Those studies are ongoing.
They're fully involved.
What we have to do, what Gilead has to do to get the combination product approved is simply CMC-related and the bioequivalent study.
We have to provide information about the formulation, about stability of the formulation, and we have to show that the fixed dose combination is bioequivalent to the components when taken separately.
This is very similar parallels to the development of Truvada, where we only had a bioequivalence study and CMC information, and also Atripla was filed and approved entirely on bioequivalence and CMC.
I hope that answers your question.
Geoff Meacham - Analyst
It doesn't.
So, I'm trying to reconcile maybe the market impact of that data versus what's the impetus for switching a patient, or for an Atripla script over a combo with TMC278, just looking out a couple of years.
Norbert Bischofberger - CSO, EVP of R&D
I think the utilization of the TMC278 fixed dose combination versus Atripla versus others will be entirely determined by the Phase III data that are going to emerge.
Atripla is very good drug but it is not perfect.
So, if we could diminish the CMA side of it, the rash, have a better pregnancy category, that would automatically be an incentive for people to use the TMC278 fixed dose combination over Atripla.
Of course, those things all have to be shown or proven in Phase III studies.
John Milligan - President, COO
Yes, but this is John.
We do know there are some underlying shortcomings in that there are significant long-term CNS side effects, and you are seeing that in other studies that are looking at Sustiva.
So, it is the weakest link in there.
One thing that Norbert didn't say with regard to the Phase III study that Tibotec is conducting is the study design itself.
In one study, both arms have Truvada and it is Sustiva versus TMC278.
So that's really just a study of Truvada, it's the perfect study for us.
The second study was a similar design of Sustiva versus TMC278, and doctors were allowed to choose whichever backbone they wanted.
But of course as consistent with the market, over 80% of those patients are on Truvada.
So essentially we have both Phase III studies conducted by Tibotec based on that enrollment criteria.
And that's what's going to allow us to make the bioequivalent study, the next study necessary for approval rather than having to conduct additional studies.

Yaron Werber with Citi.
Yaron Werber - Analyst
Yes, hi.
Thanks for taking my question.
I just wanted to ask, the (inaudible) session looked very good this quarter.
Can you give us a sense a little bit?
You mentioned inventories were stable, or what was the destocking last quarter so at least we'll understand what is the normalized run rate.
And is the $3.6 million sale to Menarini, is that a normalized run rate from now on also, because that also looked pretty good.
Thanks.
Kevin Young - EVP, Commercial Operations
Hi, Yaron, it is Kevin.
Yes, there was really quite a large drop-off from Q4 to Q1.
That was probably in the area of about -- something like about ten days.
That's the best of our estimates.
So, it really was a considerable draw down by the wholesalers.
As I said, of the reported $36.1 million for us in Q2, $3.6 million of that was the booked tablets that went to Menarini.
In the first quarter, it was actually $2.6 million that went in terms of booked tablets to Menarini.
We'll have to see how that develops.
A lot of it will depend, of course, on the performance of Menarini.
They are now making big efforts with Ranexa, particularly in Germany where they have a very sizable field force and that's a large market.
A lot of it will depend upon how successful they are over there.

Michael Aberman with Credit Suisse.
Michael Aberman - Analyst
Hi, thanks.
I don't mean to go back to the inventory levels and what not, but Viread, for example, you're getting increased penetration in HBV setting, and yet you have a down sales quarter-over-quarter.
Can you help us understand what's going on there, the dynamics?
Are you giving away free drugs in the HBV setting?
Fee-based (multiple speakers)?
Kevin Young - EVP, Commercial Operations
Yes, certainly.
Getting some mixed issue with Viread, please appreciate that 75% of Viread is still HIV.
Now, when we began selling Viread for HBV, only about 4% of total Viread sales were coming from the HBV setting.
That's where we started at.
Now, it is up to about 25%.
But you've got a very large kind of swamping effect from HIV.
As I said earlier, because the nonretail came down across the board for our HIV products, that affected Viread and therefore that affects Viread -- HIV in the mix of total Viread prescriptions.
The mismatch that you are kind of seeing between the growth in HBV and our actual product sales is very much this -- is very much this issue of HIV.
Michael Aberman - Analyst
Maybe -- I'm sorry, just a follow-up.
Can you help quantify?
You specifically mentioned that there could be a decline in inventory that has an impact on the second half.
How about the nonretail?
Do you expect it to go back to normal and to have a positive impact on the second half?
Kevin Young - EVP, Commercial Operations
One thing we know, shape is always difficult during the year.
But the one thing we do know because this has been given out by HRSA, we do know the budgets for financial year 2009.
And they're about the same.
They are slightly higher, but for all intents and purposes, they're the same for 2008.
That's the best we know.
I think there will be a shape, because the financial year always goes through to the end of March.
So, [Pete], they tend to use their budgets during the first quarter of the year.
But exactly how it plays out is always difficult to peg.
Michael Aberman - Analyst
All right.
Thanks.
John Milligan - President, COO
One other thing that maybe didn't come through is that we talked about inventory levels, we were specifically talking about Truvada and Atripla, with regard to Viread's inventory levels did come down quarter over quarter.
As you may recall, we did implement a price increase on April 1 for Viread.
And so inventory had probably grown a little bit in anticipation of that price increase and then did come down to lower levels during the course of this quarter as well which affected the overall Viread sales level.

Ian Somaiya - Analyst
Thanks for taking my question.
Just strategy, I wanted to get a better understanding of the strategy for triple combination HIV pills.
Is it one of picking the best third drug in a given class?
Or is it going to be a classic blitzkrieg, let's try to get any and all combination pills we can, so at least Truvada remains a backbone and you might be able to get some level of profitability on the third drug?
Any comments would be useful.
John Milligan - President, COO
Hi, Ian.
It is John Milligan.
So a couple things to say.
You always want to work with the best drug in a category.
That's always very clear.
It would be, I think, advantageous for us to do additional products.
There are debates over which is the best drug in a category, of course.
So, is there a possibility for us to do additional combination studies -- I'm sorry, combination collaborations?
I don't think we can do too many more of them, because of the complexity of the business that we're running.
And also because there are other options that we are trying to develop internally for the long-term as well.
But there is, I think, the possibility that we could do one protease inhibitor collaboration.
There are some good choices out there to do that.
Especially if 9350 plays out the way we hope, because that could allow other proteases to be much more successful than they are today.
There is some really interesting science and clinical data that we'll have to sort through as we make the choices going forward.

Good afternoon.
Thanks for taking my question.
The question is actually on the quad combo pill.
I know you briefly gave us an update in the prepared remarks.
Could you talk more about the milestones you expect for that pill over the next, say six to nine months?
For example, will you give us some data by the end of the year in advance of the medical meeting, and what's your latest thinking on when the Phase III could begin?
Norbert Bischofberger - CSO, EVP of R&D
And so Phil, quickly, so the two Phase II studies are fully enrolled.
We anticipate having the 24-week endpoint will be reached before the end of this year.
So we will have the data available.
We anticipate, if everything goes well, to submit those to some meeting early next year.
Based -- with those data in hand, we would then approach FDA and get final agreement on the development plan.
Overall, I don't think it's going to be any controversy because it's fairly straightforward.
It's simply we're proposing to do two Phase III studies in treatment naive patients.
We actually proposed that to FDA already.
They didn't have any issues or comments with it.
And so to make a long story short, we would hope to initiate those Phase III studies in the first half of 2010.
So, sometime second quarter of next year.
Philip Nadeau - Analyst
Okay.
And just a clarification.
You say you're going to have the 24-week endpoint data by year-end.
But it sounds like you're not going to release that; you'll just wait until the medical meeting?
Norbert Bischofberger - CSO, EVP of R&D
No.
We would -- I mean, the devil of course is in the details, but I think to a medical conference or a scientific conference early in 2010, we would be in a position to submit the data.
Philip Nadeau - Analyst
Okay.
Thank you.
Robin Washington - SVP, CFO
Operator, this is Robin.
Before the next call, I did want to make a clarification on the guidance.
We did receive a question regarding whether our guidance for R&D expenses from $800 million to $820 million to a range of $850 million to $870 million.
We were asked if it did include any part of the reimbursement payable to Tibotec and it does.
A substantial portion of that increase is related to Tibotec.
So I wanted to provide that clarification.
John Milligan - President, COO
And the way to think about the substantial portion is that this reimbursement will be billed to Gilead and it will go over a couple of years.
So, be there will be some portion for this year, and some portion for next year.
And this is the maximum amount that would be allowable -- that Tibotec would be allowed to bill us under the contract for this year.
We don't know if they will bill all that.
And we'll update you in the future if they bill us for less.

Sure, hi.
Can you discuss the European ordering patterns for the HIV franchise in the quarter?
Were there any unusual orders?
Kevin Young - EVP, Commercial Operations
Hi, it is Kevin.
Not really.
We saw strong underlying demand.
There was a little bit -- a little bit of extra ordering in Spain.
This is a funny time period for particularly the major continental European markets, Italy, Spain, France, a lot of holidays take place, so, pegging, judging that right is always a fine art.
But no, largely, the quarter was as we expected.
Obviously we're doing extremely well with Atripla in the UK, in Spain, we now have Italy growing and of course we had about two months worth, our first two months of sales in France.
So, it was very, very much driven by the pick up in Atripla.
Maged Shenouda - Analyst

Josh Schimmer with Leerink Swann.
Josh Schimmer - Analyst
Hey.
Thanks for taking the question.
If you did decide to roll the Phase II quad studies into two Phase II/III trials, will we still see the interim data?
John Martin - Chairman, CEO
[You'll put out] the interim analysis, Norbert?
Norbert Bischofberger - CSO, EVP of R&D
Yes, we could -- you're asking if we would run it into a Phase III study.
No, under that scenario we would not be able to release the data.
So, we're debating that currently internally.
But I think the way -- since the rate limiting step for approval of the quad will be the second Phase III study against the protease inhibitor, that's why I think it wouldn't buy us much if we would convert the Phase II study into a Phase III study.
So, our current thinking right now is to start two new Phase III studies, one against Atripla and one against a protease inhibitor.
Josh Schimmer - Analyst
Okay, thanks.
Operator
Joel Sendek with Lazard Capital Markets.
Joel Sendek - Analyst
Thanks.
I have a competitive question.
So, with Isentress for the front line label and they're testing it potentially as once a day, do you view that as more of a threat now than it used to be and what are you doing to defend against it?
John Milligan - President, COO
Is it that much more of a threat?
This plan has been known for some time that they were going to go for once a day.
We don't know if it will be successful or not successful.
For our money, a value of having this in a fixed dose combination really takes away much of that competitive threat, unless they can find some other way to co-formulate it with something else and put it in a first line.
Because to co-formulate a product, there's so much more advantageous to patients and they tend to have better outcomes.
One of the problems as you get into non fixed dose combinations is patients make choices to take partial regimen, and that's where you get the higher levels of resistance and the higher levels of failure in real world areas.
And so, I think the value of fixed dose combinations are well-known to physicians and will be the preferred route because of the longer term benefits.
Kevin Young - EVP, Commercial Operations
And Joel, just to kind of reassure you today, in terms of sort of the two-third agents that are really sort of growing right now, with Prezista our penetration of Gilead partner products is 88%, which is in the naive setting.
And with Isentress, it's 84% of patients.
Largely, that's Truvada.
Some of it is sometimes Viread, but largely Truvada.
So you can see that over eight times out of ten, Prezista or Isentress is partnered with Gilead.

Jason Kantor - Analyst
Hi.
Thanks for taking my call.
Most of my questions have been asked, but with regard to your tax rate, you said there was some resolution of audits, but also geographic mix.
I'm wondering where you're getting those benefits geographically, and if that might persist into future quarters.
And then on France, with the launch there, how much of the uptake was due to kind of filling the channel there, inventory build in France?
Robin Washington - SVP, CFO
I'll take the first half, Jason and then Kevin will cover France.
The majority of the tax rate reduction was generated by a completion of our tax audit and our ability to get rid of reserve.
Overall, we continue to see continued upgrade and improvement in international growth, primarily Europe.
And because we have the tax structure, higher international European revenues drive our overall rate down.
So, that's something that we see continue to the extent we continue to generate more profit overseas.
Kevin Young - EVP, Commercial Operations
And in terms of France, this was not a very large bolus going into the wholesalers.
Obviously we did supply the wholesalers in France, but this was not a big load.
Please appreciate that the component products are available.
Also France is biased toward the protease inhibitors and therefore the use of Truvada.
I think what gives us a lot of confidence in these first couple of months is that the uptake on the driven therapeutic committees was virtually, virtually total in terms of the 180 plus HIV centers in France and all of the large centers in Paris, as I said, particularly the large assistance public hospitals which are very, very large are prescribing.
So, I think the first quarter, obviously truncated, was about demand as opposed to a big wholesaler load.
Jason Kantor - Analyst
Thank you.
Operator
Tom Russo with Baird.
Tom Russo - Analyst
Thanks.
I wanted to ask a question somewhat related to inventories.
But what is your best read as we're in the -- looking at the second quarter of underlying market growth in the US.
Does it still feel like 7% to 9%, which has been pretty consistent the last few years, or does it feel like something else?
And then with regard to guidance, what would guidance -- how would it have been revised just based on the core business, as opposed to CV Therapeutics and other moving parts.
Kevin Young - EVP, Commercial Operations
In terms of the market, defined as the antiviral market, the annual growth is remaining pretty solid.
It was 7% and actually likewise in Europe.
So, those numbers are very consistent.
We still see a high need out there for increased testing and linkage to care.
We're still seeing very high incidents of HIV in the large cities, and the incidents growing into the southeast of the US.
So, certainly, I think there remains very, very high profile and we have the appropriate government -- government policy people, as well as community-based, field-based people, who are continuing to discuss the need for increased testing and linkage to care, i.e., putting into the healthcare system.
Robin Washington - SVP, CFO

Tom Russo - Analyst
(multiple speakers) I apologize.
I was asking about Q2.
I think the market research that you've shown usually has a quarter lag.
And I just wanted to really figure out if there is anything that looks or feels any different even anecdotally in the second quarter.
Kevin Young - EVP, Commercial Operations
No.
Obviously we're always a quarter behind here in the US, Tom.
And so, we don't know the accurate figure for Q2, but there's nothing that we have seen during this quarter that would say that there's been some falloff in that type of growth.
Robin Washington - SVP, CFO
Tom, this is Robin.

So, Ranexa was factored into that guidance, but we won't provide a breakout by therapeutic area or product.

Geoff Porges with Bernstein.
Geoff Porges - Analyst
Thanks very much for letting me sneak in a second question.
John and Robin, you've got a lot of moving parts here -- Atripla, the next triple, Truvada, the quad, a patent expiry for Sustiva.
How should we think about our margins going forward?
You've had a bit of a trend down here.
Do you think that you can sustain margins, particularly operating margins at the current level or around the current level as you go through all of these transitions?
Robin Washington - SVP, CFO
Geoff, it is Robin.
Again, relative to our overall guidance, we do factor in margin as you know.
But the more we sell of Atripla, it does create an overall drag on our margins, but we focus operationally on our core margin exclusive of Atripla or the Sustiva component of Atripla, as well as Tamiflu.
So, it is something that we watch and monitor very closely.
Clearly, if you look at second half 2009, we're impacted by the fact that we're integrating two companies.
So, we've got infrastructure in place for two companies that we'll continue to work through.
The CVT impact on our overall EPS, if you look at it operationally, was about $0.01.
So, we feel pretty comfortable that we can maintain our operating margins overall going forward.
Geoff Porges - Analyst
Robin, would you agree with that longer term?
John Milligan - President, COO
Well, I mean, Geoff, we continue to try to run a very efficient business.
I think as Robin just pointed out, the small EPS impact already that CVT is having on Gilead shows we can run a very efficient organization and that we're focused on it.
If you think about the R&D guidance Robin provided today, the vast majority of that increase in R&D guidance relates to the payments to Tibotec.
And so we're able to rationalize efficiently, we are able to run this business and with a focus on those operational margins and we're going to continue to do so for the future.
I can't give you guidance for 2010 or beyond, but I know that -- you know as we discuss it during the course of the year, we're heavily focused on keeping this business running very efficiently.
And that won't change for us.

Where are you guys in the preparations for launch in the EU?
And can you highlight maybe the key differences from a regulatory view between what the EMEA and Canadian regulatory authorities think compared to the US?
Kevin Young - EVP, Commercial Operations
Hi, Geoff.
It's Kevin.
I'll take the first part of that.
Yes, we're just getting the European markets ready.
I would say two things.
It is probably a fairly modest potential in Europe.
As I think you may know, there are a lot of compounded products used in Europe, [Calistan] is really quite popular.
The UK uses a lot of Calistan.
I think the market that's most attractive to us both in terms of incidents, prevalence of the disease as well as actually the ability to have a good price and usage is Germany.
So, that's going to be one of our first markets.
So, I think -- I think Germany is probably top of our list to have a successful introduction.
We also, I think, will eventually need that head-to-head data, the study that we're running versus [TOBI] to really make it an attractive market in Europe.
Norbert Bischofberger - CSO, EVP of R&D
Just the two regulatory approvals or almost approvals we have in European Union and in Canada are both conditional approvals.
What that means is we have to conceal certain conditions which essentially is the completion of ongoing studies.
That's not the case in the US and we're still in discussions with US FDA about the approval of aztreonam and we hope to make some progress.
But if they don't agree to our dispute resolution, we do have the study in place and it is (enrolling) that will get us approval in the United States as well.

If you were to exclude CVTX from your revenue guidance update, could you help us understand where it would have come out to be?
Robin Washington - SVP, CFO
Sapna, it's Robin.
As I mentioned earlier, we don't break out our guidance by product of therapeutic area, so it is inclusive of overall net product revenues and we have factored in Ranexa into that guidance.
Sapna Srivastava - Analyst
Just not to beat a dead horse, but maybe one quick follow-up again.
So, should I -- how should we think about like non detail balancing out the inventory aspect of it.
I mean are they mostly comparable or does one outweigh the other?
Kevin Young - EVP, Commercial Operations
Sorry, the nonretail versus --
Sapna Srivastava - Analyst
The increase of inventory levels marginally boosting the Atripla and Truvada revenues and the non detail coming down slightly.
If I just had to like figure out exactly where the midpoint would be, I mean should I think of them kind of canceling each other when I think of the run rate going forward in the future quarters?
Kevin Young - EVP, Commercial Operations
There was a certain degree of canceling.
As I said earlier Sapna, the drop-off in Q2 was not as substantial as it was in 2008.
That's probably as much color as I can provide you.
