Operator

Ladies and gentlemen, thank you for standing by, and welcome to the Boston Scientific Q1 2013 Earnings Call. [Operator Instructions] Also as a reminder, this teleconference is being recorded. And at this time, we will turn the conference call over to your host, Vice President of Investor Relations, Mr. Michael Campbell. Please go ahead, sir.

Michael Campbell

Thank you, Tony. Good morning, everyone, and thanks for joining us.

With me on today's call are Mike Mahoney, President and Chief Executive Officer; and Jeff Capello, Executive Vice President and Chief Financial Officer.

We issued a press release earlier this morning announcing our Q1 results for 2013, which included reconciliations of the non-GAAP measures used in the release. We have posted a copy of that release as well as reconciliations to GAAP of the non-GAAP measures used in today's call, along with other supporting schedules, to the Investor Relations section of our website under the heading Financial Information.

The duration of this morning's call will be approximately 1 hour. Mike will begin our prepared remarks with an update on our business progress and his perspectives on the quarter and for the remainder of 2013. Jeff will then review our Q1 financial results and business performance as well as Q2 and full year 2013 guidance. We will then open the call up to questions. During today's Q&A session, Mike and Jeff will be joined by our Chief Medical Officers, Dr. Dawkins and Dr. Stein.

Before we begin, I'd like to remind everyone that this call contains forward-looking statements within the meaning of federal securities laws, which may be identified by words like anticipate, expect, believe, estimate and other similar words. These forward-looking statements include, among other things, statements about our growth and market share; our market-to-market trends; our products, including product approvals, launches and performance; procedural volumes and pricing; regulatory filings; clinical trials and results; cost savings and growth opportunities and their expected impact; our cash flow and expected uses; our expected financial performance, including sales, margins, earnings and other guidance for Q2 and the full year 2013; tax rates and tax impact, R&D spend and other expenses.

Actual results may differ materially from those discussed in the forward-looking statements. Factors that may cause such differences include those described in the Risk Factors section of our most recent 10-K and subsequent 10-Qs and 8-Ks filed with the SEC. These statements speak only as of today's date, and we disclaim any intention or obligation to update them.

At this point, I'll turn it over to Mike for his comments. Mike?

Michael F. Mahoney

Sure. Thanks. Thank you, Michael, and good morning, everyone and thank you for joining us. I'll begin today with some comments regarding our first quarter performance, which Jeff will cover in more detail a little bit later.

On an operational basis our sales performance came in at the midpoint of our stated guidance range for the quarter. We delivered net sales of $1.761 billion, which is down 6% on a reported basis and down 4% on an operational basis, and this excludes the impact of foreign exchange and the divested Neurovascular business.

So as anticipated, the year-over-year comparisons in the first quarter were challenging from a top line perspective, primarily driven by DES comparisons and the impact of fewer selling days than in the prior period. We estimate the negative impact of fewer selling days in Q1 2013 to be approximately 200 basis points from a year-over-year growth perspective. And in addition, FX is more of a headwind than anticipated in our first quarter guidance range. However, 5 of our 7 businesses, after adjusting for the fewer selling days, continue to grow at or above the market during the quarter. The revenue growth figures that I will highlight on this call are all on a constant currency basis.

On a worldwide basis, Neuromodulation grew at 6%, Endoscopy grew at 5% and Peripheral Interventions grew at 3% as compared to Q1 of last year. We continue to see strong returns on our investments in emerging markets during the quarter, with combined revenue in Brazil and Russia, India and China growing 35% as compared to first quarter '12. We're also pleased with improved performance of our CRM business relative to the market performance.

In terms of EPS, we delivered adjusted EPS of $0.16, which is at the higher end of our guidance range and at Street consensus. On a year-over-year basis, we delivered adjusted EPS growth of 7%, even after absorbing a $0.01 impact in the quarter due to the medical device tax. We also generated solid cash flow and used $100 million to buy back approximately 13 million shares of stock in the quarter. So now let me go into more detail regarding our business performance for the quarter, and we'll start with our MedSurg sector.

So in Endoscopy, we had a solid quarter with 5% revenue growth worldwide driven by strong results internationally. So despite the fewer selling days, we experienced broad year-over-year growth across several of our key product franchises in the quarter. Our Metal Stent franchise led the way driven by our industry-leading WallFlex product family. Our Hemostasis franchise continued to strengthen based on the adoption and utilization of our resolution clip for GI bleeding. And our Biliary device franchise continued to grow faster than market via our Endoscopic Ultrasound platform. In addition, we continue to see improved adoption for the Alair platform. There continues to be a sequential increase in the number of patients seeking treatment, as well as an increase in private payers covering this procedure on a patient-by-patient basis through the predetermination process.

In the quarter, we continued to see an increase in sites, exceeding 250 centers across 18 countries. And we also expect to publish 5-year safety and efficacy data by the third quarter of '13 and continue to execute a focused coding coverage and payment strategy for the important and very differentiated technology. So overall, we believe the worldwide markets in endo are healthy, and we continue to drive above-market sales growth performance on a global basis in 2013.

In our Urology/Women's Health division, revenues in the quarter were flat compared to the prior year as our growth in Urology was offset by a challenging pelvic floor market in Women's Health. We continue to see strong international growth as a result of our global commercial expansion and effective new product launches. In the U.S., we successfully launched 5 new products, 3 in Urology and 2 within Women's Health. We expect this division to return to growth in the second half of 2013 given our pipeline, further global expansion and the anniversary of the pelvic floor market declines.

Turning to Neuromodulation. Our team is executing very well as we continued to gain market share during the quarter, particularly in the U.S. For the quarter, we delivered 6% revenue growth on a worldwide basis despite the fewer selling days. We recently received FDA approval for our Precision Spectra Spinal Cord Stimulation platform in the U.S. The Spectra platform is the world's first and only system with a three-dimensional programming algorithm and 32 dedicated power sources that will provide patients pain relief to a wide range who suffer from chronic pain. We are currently in limited launch in the U.S. and have been pleased with enthusiastic physician response. Precision Spectra is another example of our emphasis on clinically meaningful innovation focused on patient outcomes, and we have high expectations for this platform going forward.

So despite consistent procedural growth outside the U.S., as expected, we continue to see the worldwide Interventional Cardiology market decline in the low- to mid-single digits driven by procedural softness in the U.S. plus global pricing pressures. While we expect these market headwinds to persist, we believe they will moderate over time due to underlying patient demographics and introduction of differentiated technologies such as our SYNERGY Stent platform.

During the quarter, we estimate that our IC sequential global market share was essentially flat. Our worldwide IC revenues declined 14%, driven primarily by the U.S. In the U.S., as expected, we experienced difficult comparisons to first quarter 2012. We saw the launch of PROMUS Element Plus and predated the U.S. introduction of Resolute Integrity. The difficult comparisons should end in late second quarter 2013, reflecting the anniversary of a competitive launch in the U.S., and we estimate our first quarter U.S. DES share to be in the mid-30s.

In addition, we anticipate an improvement in our IC revenue performance starting in the second quarter, primarily driven by new product launches and improving global commercial execution. In terms of our U.S. -- I'm sorry, in terms of our DES pipeline, our next-generation SYNERGY Stent continues to perform very well. The limited launch we began in Europe after receiving CE Mark approval late last year has been progressing according to plan and expanded to include our Asia Pac region. Globally, customer feedback continues to be very positive, and the selling price has been healthy even in our most challenging markets. Further, enrollment in the SYNERGY U.S. IDE trial, called EVOLVE II, is tracking ahead of schedule with over 500 patients recruited to date.

In February, we announced CE Mark approval of a new stent platform in our DES portfolio. It's called Promus PREMIER. The introduction of PREMIER is another example of our commitment to leadership and innovative product cadence. So PREMIER will enhance deliverability, and is the only platform to have customized stent architecture and other novel features that increase both axial strength without compromising the key performance. We recently began a European launch, and customer feedback has been very positive. Data from the first human U.S. trial -- first human use trial will be presented at a late-breaking trial at EuroPCR next month. We anticipate FDA approval for Promus PREMIER in the fourth quarter of 2013.

So with our PROMUS durable polymer platform, combined with our synergy bioabsorbable platform, we believe that we have the most compelling DES portfolio and pipeline in the industry. So with continued focus on commercial execution, a strength in overall IC pipeline and continued favorable clinical evidence of our DES platforms, we believe that we have stabilized our DES share and that we expect to grow our DES share in the second half of 2013.

In our core IC business, we improved our performance sequentially despite continued procedure softness. We continued the U.S. launch of the Emerge Balloon Catheter during the quarter, and that continued to receive positive feedback from customers. In addition, we accelerated our commercial rollout of the BridgePoint Medical suite of coronary CTO devices that add to our unique and clinically differentiated portfolio of IC products, all of which, we believe, enable us to be uniquely positioned to provide treatment for complex PCI procedures.

So turning to Structural Heart. On the Structural Heart front, we continue to make progress in TAVR with the Lotus Valve. Lotus is a highly differentiated, second-generation valve that is fully repositionable and recapturable post deployment. At ACC, favorable 6-month data for the REPRISE I trial demonstrated minimal paravalve regurgitation, which is an important determinant of late outcomes. Enrollment in REPRISE II, our 120-patient CE Mark trial, is now complete, and we expect the early results will be presented at a late-breaking trial at EuroPCR next month. We anticipate commercialization of the Lotus Valve after CE Mark in the fourth quarter of 2013.

So moving on to Peripheral Interventions. So despite the fewer selling days, PI delivered worldwide revenue growth of 3%. Global revenue growth was led by certain countries in the Asia Pac and Latin American regions that delivered consistent double-digit growth again this quarter. We're also making excellent progress on integrating our next-generation renal denervation system Vessix, and believe we are on track to launch this platform commercially in Europe and other international markets ahead of schedule.

Vessix is a differentiated low-energy, bipolar, over-the-wire device which offers predictable renal ablation coupled with rapid procedure times. We remain optimistic both about the opportunity of the renal denervation market and our position in it. Overall, we believe that the worldwide market in PI is healthy, and we will continue to drive above-market growth both in the U.S. and globally in 2013.

So now let's focus on our Rhythm Management segment. We are pleased with the improved performance of this business. In the first quarter our worldwide CRM business declined 4% in a market that we believe was down mid-single digits versus prior year. In our defib business, we continue to drive de novo share gains with the INCEPTA and ENERGEN family of ICDs, which lead the industry in longevity. And in an environment where hospital and cost pressures continue to increase, we believe now more than ever that the device longevity and its potential to reduce hospital readmissions and infections will continue to be a key differentiator for Boston Scientific. In addition, sales of our highly reliable RELIANCE family of ICD leads remains very strong, leading to a 5th consecutive quarter of elevated lead per port ratios.

So let me now provide an update on our controlled launch of the S-ICD system. During the first quarter, our sales exceeded our internal global forecast and demand has outpaced our ability to supply. We continue to make progress in our efforts to enhance the S-ICD supply chain following early FDA approval last fall. But despite these efforts, we had been supply constrained since early March, and we will only be able to provide a very limited supply of S-ICD in the second quarter. We are managing the supply shortage with our customers, and we continue to work diligently to expand our production capacity. We expect these efforts will put us in a position to resume our controlled launch of the S-ICD later this summer. Despite these near-term obstacles, the strong market for the S-ICD continues to highlight the strategic importance of this innovative technology to patients and to our CRM business.

As highlighted previously, we anticipate launching our S-ICD 1.5 release device in the fourth quarter. We expect that this release will enable BSC to meet the growing demand for the S-ICD platform. While the current shortage of the S-ICD product is unfortunate, we're encouraged by the performance of our core defib franchise in the quarter and look forward to building on these successes with resuming the controlled launch of S-ICD in the coming months.

So now turning to the pacer segment. We're now approaching the 1 year anniversary of the launch of our INGENIO family of pacemakers and CRTP devices. Over this time period, we've been pleased with the performance of this platform, which include a number of new design features, including a wireless telemetry and access to our recently launched LATITUDE NXT Remote Patient Management system.

With the recent launch of LATITUDE, we are now able to provide the customers a greater flexibility in how they receive, review and manage patient data and device data. And thanks to the benefit of this new family of devices, we believe our pacer business outperform the first quarter worldwide pacer market, which we estimated declined in the mid-single digits. And from a pricing standpoint, we continue to see relatively stable pacer pricing on a year-over-year basis.

So now turning to Left Atrial Appendage Closure. The WATCHMAN product line continues to show strong growth in international markets on both the sequential and a year-over-year basis, with international revenues growing by more than 30% as compared to the first quarter of last year. From a U.S. standpoint, we continue to work through our final statistical analysis of the PREVAIL data and we expect to submit the final PMA module to the FDA in the second quarter. We expect long-term efficacy results from the PROTECT-AF trial will be presented as a late-breaking trial at HRS next month.

Finally, our EP division's worldwide revenue did decline 5% during the quarter as compared to the prior year. However, we're making good progress on several internal AFib-focused projects, and we continue to be excited by the recent acquisition of Rhythmia Medical and its next-generation mapping and navigation solutions. We have submitted all the necessary regulatory filings and expect CE Mark approval of the Rhythmia platform in the second quarter of '13, with FDA clearance expected in the second half of '13 and a full U.S.-Europe launch expected in 2014.

So to wrap up. Overall, the results of the first quarter were in line with our expectations. While we're encouraged by our performance in the first quarter, we're certainly not satisfied. We continue to direct our investments toward meaningful innovation to drive clinical and economic value by improving patient outcomes, reducing the cost of health care and increasing patient access to therapies. We made progress towards the global execution in our core markets by driving de novo share gains in ICD and pacer markets and through successfully introducing new innovative platforms, including Promus PREMIER in Europe and Precision Spectra in neuromod in the U.S.

We are making progress on several of our key strategic initiatives to expand in the high-growth adjacencies. We continue to see improved performance from our Alair platform as we expand a number of centers. We've made good progress on our Lotus Valve program, including a favorable 6-month data from REPRISE I and completion of REPRISE II trial. We believe that we're on track to launch our Vessix Renal Denervation platform in Europe ahead of schedule, and we continue to expand globally with combined revenue in Brazil, Russia, India and China, growing 35% in the quarter. So as we further build our capabilities in these countries, we expect this growth trend to continue.

We also remained focused on margin improvement as evidenced by the expansion of our 2011 restructuring program. And lastly, we continue to make important operational changes that we believe will improve our execution and strengthen our customer focus. These changes include moving to a global operating structure across all of our business units during the quarter. We believe this structure is enabling us to operate more efficiently and effectively by improving our speed in global resource allocation. And as a result of this important change, we have now established new and different financial reporting segments, which Jeff will further discuss in his section.

So in the second quarter, we expect revenue performance to improve versus first quarter, with sales guidance of minus 2 to plus 1 on an operational basis. As we look forward to the remainder of 2013, we expect to stay committed to our productivity initiatives. We continue to be focused on continuous improvement and on executing on our restructuring initiatives to reduce costs and improve margins, while we prudently invest in our strategic initiatives for future growth. We expect to continue to generate strong cash flow, which enables us to fund more share purchases and to continue to look at appropriate acquisitions to improve our future growth profile. We continue to believe that we'll return to growth in the back half of 2013, with our full year sales guidance at negative 1.5% to positive 1.5% growth as we anticipate sequential quarterly growth improvement. We believe the steps we have taken are what is needed to improve our performance and return BSC to consistent revenue and EPS growth.

So now let me turn the call over to Jeff to review our first quarter results and to provide guidance for the second quarter. Jeff?

Jeffrey D. Capello

Thanks, Mike. Let me begin by providing some overall perspective on the quarter before getting into the details. Despite challenging year-over-year comparisons, we generated adjusted earnings per share of $0.16, which is at the higher end of our guidance of $0.14 to $0.17 and at consensus. This represents improved profitability from the prior year, which is driven by continued gross margin improvement, lower operating expense, a favorable tax rate and fewer shares outstanding, partially offset by a $0.01 impact from the medical device tax and increased investments in our strategic growth initiatives. In addition, we generated adjusted free cash flow of $166 million and used $100 million to repurchase approximately 13 million more shares in the quarter.

As noted in the earnings release and consistent with our strategic imperatives to focus on global opportunities, we completed the reorganization of our businesses from geographic regions to global business units effective January 1, 2013. As a result, we now have 3 reportable segments consisting of: Cardiovascular, which is comprised of our Interventional Cardiology and Peripheral Interventions businesses; Rhythm Management, comprised of our Cardiac Rhythm Management and Electrophysiology businesses; and MedSurg, which is comprised of Endoscopy, Urology/Women's Health and Neuromodulation. We have restated prior-period segment information to conform to the current year presentation within the exhibits attached to this earnings release.

In conjunction with the interim goodwill impairment testing required following the change in composition of our segments and reporting units, we recognized an estimated $423 million pretax goodwill impairment charge associated with our new global Cardiac Rhythm Management business unit. It is important to note that our assumptions on the CRM market and our expected operational results remain unchanged from year end, and that the primary driver of this charge was the reorganization to global business units, which changed the composition of our reporting units including the amount of intangible assets, other assets and liabilities and the expected cash flows allocated to the new global CRM reporting unit. As a result of this charge, the remaining goodwill assigned to our global CRM business has been fully written off. As a reminder, this is a noncash charge with minimal tax consequences and has no impact on our expected cash flows or our bank covenant ratios.

We firmly believe our Rhythm Management business represents a future growth opportunity for the company given our new products and future technology offerings. We believe that over the past several years, we've invested in technology and acquisitions to improve the company's growth profile. Some of these investments have been used to revitalize our core CRM portfolio and to provide the EP with a comprehensive set of solutions, including differentiated platforms such as the S-ICD, the WATCHMAN device and the recently acquired Rhythmia mapping and navigation systems. As this focused strategy continues to gain traction, we believe we can drive Rhythm Management's profitability to levels more consistent with our other business segments.

Now I'll move to the detailed review of our business performance and operating results for the quarter. For the first quarter of 2013, consolidated revenue of $1,761,000,000 represents a decrease of 6% on a reported basis and a decrease of 4% on an operational basis, which excludes the impact of foreign exchange and the divested Neurovascular business. The actual headwind from foreign exchange on sales was approximately $35 million as compared to the prior year and was $25 million higher than what we had assumed in our first quarter guidance range.

On an operational basis, our sales performance was at the midpoint of our guidance range and somewhat consistent with the performance in the fourth quarter 2012 after adjusting for 2 fewer selling days in the first quarter '13. It is important to note that all revenue comparables this quarter have been negatively impacted by approximately 2 fewer billing days than the prior year.

In Interventional Cardiology, worldwide revenue came in at $514 million in the first quarter, representing a constant currency decrease of 14% compared to the first quarter 2012. Worldwide DES revenue came at $291 million, representing a constant currency decrease of 18% compared to the first quarter of 2012.

U.S. DES revenue was $117 million in the quarter, representing a decline of 34% compared to the first quarter of last year. This decrease was primarily due to a strong comparison to the prior-year quarter driven by the full launch of PROMUS Element Plus, lower share to competitive products, lower ASPs and continued softness in PCI volumes in a number of devices used per procedure. We estimate that our U.S. DES share was stable sequentially in the mid-30s in the first quarter.

International DES sales of $175 million represented a decrease of 3% in constant currency compared to the first quarter of last year, driven by over 60% growth in the emerging markets of China and India, primarily offset by pricing declines in Europe and Japan. Worldwide non-stent Interventional Cardiology was down 7% in constant currency. However, with upcoming launches of new products, along with the ongoing success of BridgePoint Medical suite of CTO devices, we expect to see improvement in this business over the course of 2013.

Moving on to CRM. Worldwide revenue was $478 million in the first quarter, representing a constant currency decrease of 4% compared to the first quarter of last year. In the U.S., CRM revenue of $283 million represented a 3% increase from the first quarter of 2012. International CRM sales of $195 million were down 5% in constant currency compared to the prior-year quarter.

On a worldwide basis, defib sales were 5 -- were $350 million in Q1, which was down 4% in constant currency from the first quarter of 2012. In the U.S., defib sales were $221 million. This was down 4% compared to Q1 last year. International defib sales of $129 million represented a 5% decrease in constant currency in the first quarter of last year.

Worldwide pacer sales declined 2% on a constant currency basis as compared to Q1 2012, driven by continued strong performance from our INGENIO family of pacemakers and CRTPs. In the U.S., pacer revenue was flat compared to the first quarter of last year, while international revenue declined 4% in constant currency for the quarter. Additionally, our worldwide Electrophysiology business declined 5% on a constant currency basis compared to the first quarter of last year.

Our Peripheral Interventions business continued to deliver growth, with worldwide revenue up 3% in constant currency compared to the first quarter of last year. Global growth was driven by strong performance in Asia, up 27% and 13% growth in Latin America. Our Endoscopy business continue to grow faster than the market and had another solid quarter, with worldwide sales up 5% in constant currency led by 7% revenue growth internationally.

In constant currency, our worldwide Urology/Women's Health business was flat from a growth perspective during the quarter. However, sales growth was particularly strong internationally at 7% compared to the first quarter of last year. Our Urology business maintained its leadership position with 2% worldwide constant currency growth in the quarter driven by strong international revenue growth of 6%.

Our Women's Health revenue declined 7% on a worldwide constant currency basis as compared to the prior year. However, our international business had a 4% growth on a year-over-year basis. We continue to see pressure on elective procedures due to concerns around the use of surgical mesh for pelvic organ prolapse, specifically in the U.S. market.

Neuromodulation had another solid quarter with 6% worldwide sales growth, including 36% growth in our international revenue compared to the same period in the prior year. We expect to sustain and build on this momentum in the remainder of 2013 as we fully launch Precision Spectra in the U.S. spinal cord stimulation market.

Moving on from sales. Adjusted gross profit margin for the first quarter was 67.3% or 80% -- 80 basis points higher than the first quarter of last year. The increase was largely attributed to the mix shift towards self-manufacturing product in DES as a result of the launches of PROMUS Element in U.S. and Japan in the prior year, as well as benefits from our value improvement programs, partially offset by price erosion, mix and some product transition costs. Looking forward, we expect adjusted gross margins to be between 68% and 69% for the second quarter and to improve sequentially as the benefits from our value improvement programs are expected to increase as we progress through the year.

Adjusted SG&A expense was $626 million or 35.5% of sales in the first quarter of 2013 compared to $654 million or 35% of sales in the first quarter of 2012. During the first quarter of 2013, the impact from our cost-saving programs were offset by continued investments in our strategic growth initiatives and costs associated with expanding in emerging markets. In addition, SG&A expenses in Q1 '13 include the impact of approximately 100 basis points from the medical device tax under the U.S. Affordable Care Act. Currently, the accounting treatment for the medical device tax is not consistently applied across the industry. We expect to absorb the first full year impact of the medical device tax during 2013.

Looking ahead, we expect adjusted SG&A as a percentage of sales to be between 35.5% and 36.5% in the second quarter of this year as we expect to accelerate investments in our strategic growth initiatives in preparation for the commercialization of several new technology platforms, plus continue to build our capabilities in emerging markets.

Adjusted R&D expenses were $204 million for the first quarter or 11.6% -- 11.6% of sales. This compares to $215 million in the first quarter of 2012. We expect R&D spending to be in the range of 11.5% to 12.5% of sales in the second quarter of this year as we continue to transform our R&D organization and refocus our spending to drive innovation and growth. Royalty expense is $41 million or 2.3% of sales compared to $48 million in Q1 last year. We expect Q2 royalty expense to be higher than the first quarter of 2013.

On an adjusted basis, pretax operating income was $314 million or 17.8% of sales, up 50 basis points from the first quarter of last year. The increase in adjusted operating margins was primarily due to higher adjusted gross margins and lower operating expenses, partially offset by the impact of the medical device tax. It is very important to note that the medical device tax negatively impacted our operating margins by 100 basis points. Accordingly, our margin expansion would have been 150 basis points without this tax.

GAAP operating loss, which includes GAAP to adjusted items that had a negative impact of $643 million on a pretax basis, was $354 million in the first quarter of 2013. The primary GAAP to adjusted items in the quarter were: the estimated pretax goodwill impairment charge of $423 million that I just discussed earlier; a pretax net litigation charges of $130 million and pretax amortization expense of $103 million.

Now I'll move on to other income expense. Interest expense was $65 million in the first quarter, which is $4 million lower than the first quarter of last year, primarily due to the collection of Spanish government receivables and the refinancing of our revolving credit facility in mid-2012. Our average interest expense rate in the first quarter of this year was 5.7% or about 10 basis points lower than the first quarter of last year.

Our tax rate for the first quarter was 10.2% on a reported basis and 9.8% on an adjusted basis. The difference between our reported and adjusted tax rates for the quarter is attributable to the net benefit of restructuring, litigation and other net charges excluded in determining our non-GAAP results.

Our adjusted tax rate in Q1 included a net benefit of approximately $8 million for discrete tax items, primarily related to the retroactive extension of the U.S. R&D tax credit for 2012 that was recognized in the first quarter of 2013. We estimate our full year tax -- adjusted tax rate to be between 10% to 12%. This excludes any other discrete tax items that may arise during the year.

Moving on to the balance sheet. DSO is 63 days, improved 1 day compared to March 2012, primarily due to good performance in Japan and Europe. Despite lower inventory levels, days inventory on hand of 133 days was up 4 days compared to March of last year, primarily due to lower cost of goods sold primarily driven by the PROMUS Element transition and standard cost improvements.

Adjusted free cash flow for the quarter was $166 million compared to $177 million in Q1 2012. Capital expenditures were $53 million in the first quarter 2013 compared to $66 million in the first quarter of last year. We continue to expect full year 2013 adjusted free cash flow to be approximately $1.2 billion.

Turning to share repurchases. We repurchased 13 million shares in the quarter for approximately $100 million. Since July 2011, we have repurchased 200 million shares or approximately 13% of our outstanding shares. We announced in January 2013 that our Board of Directors authorized the company to repurchase an additional $1 billion of the company's stock. We continue to believe that our stock price is undervalued, and we currently expect to utilize approximately 1/2 of our estimated available adjusted free cash flow for share repurchase in 2013, subject to business development opportunities, market conditions, our stock price, regulatory trading windows and other factors.

As a reminder, we announced on our Q4 earnings call in January the expansion of our 2011 restructuring program intended to build on the progress made under that program to strengthen our operational effectiveness and efficiencies and support new investments, which we expect will increase shareholder value. From a cost perspective, we expect a substantial portion of the total program savings will be reinvested in targeted areas for future growth, including our strategic growth initiatives and continue to build our capabilities in emerging markets.

Let me now walk you through our guidance for the second quarter as well as updated guidance for the full year. Looking ahead over the remainder of the year, we continue to expect dynamic market conditions with the risks of macroeconomic weakness, particularly in Europe, and softening procedural volumes in the U.S. As a result, we are carefully monitoring conditions and have applied what we believe is a reasonable level of conservatism in our guidance to account for these factors.

However, despite these uncertainties, we continue to believe there's reason to be positive. We have acquired new technologies and have launched key new products in most of our businesses as we remain focused on returning to top line growth in the second half of 2013. We also believe, despite the medical device tax, that we have the opportunity to enhance profitability and expect to continue to generate strong cash flow.

We expect Q2 consolidated revenues to be in the range of $1,740,000,000 to $1,800,000,000. If current foreign exchange rates hold constant, the headwind from FX should be approximately $30 million, around 170 basis points relative to the second quarter of last year. On an operational basis, we expect consolidated Q2 sales to be in the range of up 1% to down 2% compared to the second quarter of last year.

On a worldwide basis, we expect DES revenue to be in the range of $275 million to $295 million and CRM revenue to be in the range of $450 million to $470 million in the second quarter. We expect Q2 adjusted EPS to be in the range of $0.14 to $0.17 per share, and we encourage you to model to the midpoint.

We expect reported GAAP EPS to be in the range of $0.07 to $0.10 per share, which includes an estimated $0.07 per share impact from amortization expense. We also wanted to remind folks to look at their models for Q3 and Q4 as historically Q3 has been our lowest quarter primarily due to seasonality, typically lower than Q2, and we expect Q4 to be our strongest quarter given seasonality and the timing of some of our expected new product launches.

Moving to the full year. We now expect the consolidated 2013 sales will be between $6,950,000,000 and $7,150,000,000. Assuming that current foreign exchange rates hold constant, we expect the full year headwind from FX to be approximately $140 million. On an operational basis, consolidated 2013 sales should be in the range of down 1.5% to up 1.5%, and we encourage you to model to the midpoint.

The range assumes that the IC and CRM markets continue to stabilize, and our revenue performance improves sequentially throughout the year, driven primarily by continued stabilization and improved performance in our IC and CRM businesses; more meaningful contribution from emerging markets and our strategic growth initiatives, plus benefits of new product launches across our divisions.

From an earnings standpoint, we expect adjusted EPS for the full year 2013 to be in the range of $0.65 to $0.70, and we encourage you to again model to the midpoint of the range. This range reflects the estimated impact of approximately $0.04 per share from the medical device tax. On a reported GAAP basis, we now expect EPS for the year to be in the range of $0.01 per share to a net loss of $0.06 per share.

That's it for guidance. So with that, I'll turn it back over to Michael, who will moderate the Q&A. Michael?

Michael Campbell

Thanks, Jeff. Tony, let's open it up to questions for the next 20 minutes or so. [Operator Instructions] Tony, please go ahead.

Question-and-Answer Session

Operator

[Operator Instructions] Our first question will come from Rick Wise with Stifel.

Frederick A. Wise - Stifel, Nicolaus & Co., Inc., Research Division

So many questions here. Let me just start with 2 product questions, since that's key to the reacceleration story. SYNERGY and the S-ICD. SYNERGY in Europe, why the limited launch? The U.S. trial is enrolling ahead of schedule. Talk about, if you would, what accelerates the launch in Europe and the impact on -- of that accelerated enrollment on U.S. filing and potential approval, if you would.

Michael F. Mahoney

Yes. So thanks, Rick. Overall, we're pleased with where -- how we positioned SYNERGY right now. We have a 2 stent platform, as you know, at SYNERGY, and then we've also launched in Europe Promus PREMIER, which we think offers a differentiated portfolio. And with SYNERGY, we're rolling ahead of schedule in terms of our enrollment in the U.S. And in Europe, we believe we're being smart in terms of how we positioned the product. We do believe that this product deserves and warrants a pricing premium, and so we're being selective in terms of markets and customers that we're approaching with SYNERGY. And we will have a full-blown launch. We'll expand that launch in first quarter 2014 in Europe, and we'll continue to enroll. But we believe that two-tiered position is the way to go, and we'll launch in the first quarter 2014 and we'll continue to do the controlled launch in the appropriate markets that justify the premium price points that the product deserves.

Frederick A. Wise - Stifel, Nicolaus & Co., Inc., Research Division

Yes. On the S-ICD front, Mike, the demand ahead of supply. I understand that with gen 1 especially. But with gen 1.5 that you're going to launch this summer, it sounds like on track. Are you -- how quickly are you going to be able to supply the demand that's there? Is it going to take 6 months or 2 years? Help us understand how quickly gen 1.5 can launch.

Michael F. Mahoney

Sure. Well on the -- in Investor Day, we talked about the S-ICD in quite a bit of detail. And we expect to continue to deliver the revenue that we discussed at Investor Day in 2013 for S-ICD. The revenue will be more heavily weighted to what we delivered in the first quarter and more heavily weighted to the back half of '13 based on the supply, but we expect to deliver that. So the -- it's not an issue of demand. As you know, the product was approved early, and so for a number of months, since we've acquired the company, we've been focused on boosting the supply chain and the capabilities with this device, so we can deliver at quality and at the right quantities. And this 1.5 release really is focused on that. And as you said, this 1.5 release will occur during the second half of the year. And we believe that we'll be able to really deliver the demand that's needed in the fourth quarter of 2013 and clearly as we go into 2014. So we'll begin to take the foot off the brake a little bit more in the third quarter. But you'll see us be able to increase our capabilities to supply in fourth quarter and clearly in 2014. And we expect to deliver the overall S-ICD guidance that we provided at the Investor Day.

Operator

Our next question in queue will come from David Lewis with Morgan Stanley.

David R. Lewis - Morgan Stanley, Research Division

Jeff, just one interesting thing on guidance, we thought, was R&D. I thought that you had talked about R&D actually being heavier in the first half of the year. And now it looks like it's going to be lighter. And it sounds to us that, that trend probably continues. So can you just talk to us about what is a good number for R&D for the year? And specifically, is this is more of a strategic structural change with how the company's going to spend and organize innovation?

Jeffrey D. Capello

Yes. David, thanks for the question. So I'd say that in the first quarter, R&D was probably a little lighter than we anticipated. And a lot of that just has to do with kind of timing and when things happen in terms of trials and activities. Our guidance indicates that R&D, as a percentage of sales, will be between 11.5% to 12.5% kind of for the rest of the year. So that would be a bit of a step-up sequentially because we're at 11.6% in Q1. So I'd expect R&D would tick up here in the second and third quarters. Those tend to be slightly lighter quarters revenue-wise and then probably be kind of at the lower end of that 11.5% to 12.5% in '14 -- in Q4 as kind of revenue picks up in the fourth quarter.

David R. Lewis - Morgan Stanley, Research Division

Okay, very helpful. And then, Mike, maybe a question on the outlook. I think the theme of the call, and I think the focus for investors is improving organic growth rates and constant currency rates throughout the balance of the year. I guess some skeptics would say you benefited from a couple of areas, specifically in CRM and Neuromodulation where some of your peers have been a little weaker. And as they begin to get a little stronger or recover from their issues in the back half of '13, it's going to be harder for you to get to that back half of the growth improvement. Maybe just kind of talk about what expectations you've made for competitors re-basing their businesses and how confident you feel that you can still get to these improvements into the back half.

Michael F. Mahoney

Yes, absolutely. We're actually pleased we delivered first quarter as we guided and the year looked -- we believe we're going to execute in 2013, similar to what we provide at the Investor Day were sequential quarterly growth. And we called the first quarter what we think will be our toughest growth, and improvement in the second quarter and a sequential improvement from there. The key factors of -- I don't want to go through the whole script, but the key factors, there's 4 of them, on why we believe we'll continue to improve the sequential growth. First one is our MedSurg and PI businesses. They continue to grow at or above market in markets that are healthier, led by Endo, the Spectra launch with Neuromod and the consistently growing PI and Urology business. And as a percent of overall BSC, that continues to grow slowly in terms of growth, in terms of the proportion of our revenue. So we think that will continue to make a positive impact each quarter in '13. The second big one, a wildcard, if you will, has been the performance of IC and CRM. And you saw a stabilization of share, we believe, in our global CRM business in the first quarter. And we expect that trend to continue, which is a strong turnaround from the previous years. Our IC business, we believe we had our worst quarter in the first quarter, and that will get better. We launched PREMIER in the second quarter in Europe. We had the full year for chronic total occlusion with our BridgePoint acquisition. And we believe a more efficient commercial organization to improve our performance in Interventional Cardiology. The adjacencies that you know about, we ticked through them during the call, the third point, are making progress in their milestones that we believe the adjacencies will deliver against the revenue that we called out at the Investor Day. And the fourth one is our BRIC. We continue to grow a solid 35% in that -- in those areas. So those are our 4-point plan there, and we believe we're executing to what we communicated at the Investor Day.

David R. Lewis - Morgan Stanley, Research Division

Okay. And then Jeff, just a real quick follow-up. Would you say the revenue guidance revision is entirely currency? And if it's not, 90% -- 95% currency, was there some other dynamic that would have driven the revision?

Jeffrey D. Capello

Yes. So if you go back and look at our original guidance for the year, I believe it's $7,050,000,000 to $7,350,000,000. So we've lowered that by $150 million, both the high end and the low end for FX. The FX rates, obviously because of the yen, predominantly have just hit everybody. So we've taken $150 million off both ends of the ranges. And then, in essence, we added $50 million of revenue to the lower end of the range, and we took $50 million off the higher end of the range. So from a percentage basis, the guidance is predominantly affected by the FX, which affects everybody. So we still, as Mike laid out, are very focused and confident on our ability to kind of return to growth. And I think we've got a lot of positive things going for us in the back of the year.

Our next question in queue will come from Glenn Novarro with RBC Capital Markets.

Glenn J. Novarro - RBC Capital Markets, LLC, Research Division

I had a question on the CRM guidance for 2Q. I think you mentioned guidance would be $450 million to $470 million. And I think you just did $478 million for the first quarter. So is that conservatism or is there something in the markets that you're concerned about? Then I have a follow-up.

Jeffrey D. Capello

Well, thanks, Glenn, for the questions. So our -- the worldwide CRM business was down 4% on a constant currency, organic basis. And our guidance would imply a low of down 7% to a high of up 3%, so the midpoint somewhere around 4% or 5%, so somewhat consistent with the first quarter. So I think we expect kind of more of the same, Q1 to Q2, being off the market in S-ICD. Obviously, it hurts us a little bit, but we see a lot of positive things, particularly in the pacer area with the INGENIO launch. So the performance is expected to be similar to the first quarter. And as I said earlier, given everything going on in the markets, I think we've leaned a little bit more conservatively on guidance and hopefully, we can exceed that.

Glenn J. Novarro - RBC Capital Markets, LLC, Research Division

Okay, and just as a follow-up, just to flesh out the U.S. market a little bit more. You're actually -- your IC number came in better than we thought here in the first quarter. Is that a function of maybe the market doing a little bit better? Was pricing not as bad? Were there share gains? Can you comment on those?

Jeffrey D. Capello

Yes. So from a market perspective, Glenn, I think we continue to be somewhat optimistic about the pricing trends. As we identified back in mid-2012, we walked away from some business which was very price-sensitive. And given our portfolio and all the new technology we have coming to market that's differentiated, we intend to continue to be disciplined from a price perspective. We did see, in the first quarter, pricing activity that was better from a percentage basis than the fourth quarter and better than kind of the trend, so that's encouraging. So that's good news. The PCIs are kind of similar, kind of down, kind of low- to mid-single digits, so unchanged on that front. So overall, we were pleased with the sequential stabilization, if not, a slight uptick in share from Q4 to Q1. But the real interest is in the back half the year when we get Promus PREMIER and we continue to roll out our CTO devices and the rest of our technology kind of takes off.

Glenn J. Novarro - RBC Capital Markets, LLC, Research Division

And then just one quick follow-up. The share comment that you thought you may have picked up sequentially, were you referring to ICDs and not enough pricing?

Jeffrey D. Capello

No.

Glenn J. Novarro - RBC Capital Markets, LLC, Research Division

Okay. So you think pricing -- share on ICDs is stable?

Jeffrey D. Capello

Yes. Well, on core ICDs, it's up I think we share -- from a share perspective. And my comment on pricing related to DES. I thought that's what you're referring to.

Glenn J. Novarro - RBC Capital Markets, LLC, Research Division

No, I was referring to ICD pricing. Generally, the ICD pricing in the overall market's been down anywhere between 3% and 5%. And then as I look at your ICD results, they did come in better than we thought. So we're just trying to figure out, was it maybe pricing came in a little bit better, were there share gains or did the overall market come in a little bit better?

Jeffrey D. Capello

Just to clarify then, so the comments on pricing, I thought you'd switch to DES, my error. On the ICD side, the pricing is no different than what it was in the fourth quarter.

Michael F. Mahoney

Yes, I think on that, just to add some color to that. The pricing is similar, as Jeff said, in ICD. We believe we picked up some share in de novo ICD in the second quarter -- I'm sorry, in the first quarter, which helped our performance.

Operator

Our next question in queue will come from Mike Weinstein with JPMorgan.

Michael N. Weinstein - JP Morgan Chase & Co, Research Division

So just to follow up, I think David's question is relative to the revenue guidance. So the 2Q, I guess, difference from where you're guiding to the $1.740 billion [ph] with the $1.800 billion [ph] versus the Street. Do you -- what do you think that is? Do you think that's just more conservatism? What is it do you think that's in your model that's not in the Street?

Jeffrey D. Capello

Well, Mike, one of the biggest differences is probably FX. And I think when the Street set their models was when we set our guidance. And at that point, we're expecting, I think, FX to be negative $10 million, and now it's negative $140 million. So it's almost $150 million negative impact of FX, and that's spread through the quarters. So what I would encourage the analysts to do is go back and kind of look at their models relative to FX because it was a $25 million negative impact in the first quarter. And I think I've said in the script it was something like $30 million, a negative in Q2? And we originally set guidance that was supposed to be minimal in Q2.

Michael N. Weinstein - JP Morgan Chase & Co, Research Division

Okay, so you think the Street is lagging on FX?

Jeffrey D. Capello

Yes, I do believe that.

Michael N. Weinstein - JP Morgan Chase & Co, Research Division

Okay. Let me ask about gross margin, because I think gross margin this quarter was a little bit lighter than I think we in the Street were looking for. And what's -- maybe just give us your thoughts on that. Is that -- is the decline or is just the -- let's call it the shortfall there, do you think is that a function just of mix and the weakness in the ICD side of the business? Is that in part because of what you sold on the S-ICD this quarter and that weighed on it? And how do we think about gross margin over the balance of the year?

Jeffrey D. Capello

Yes, sure. Thanks, Mike. So yes, so maybe the best way to do it is kind of bridge you off the fourth quarter to the first quarter, the fourth quarter of '12 to the first quarter. Why would margins be down 100 basis points? It's really 3 factors. One is a bit from a mix perspective. We had a slightly less rich mix of products, so that was about 1/3 of the impact. Another 1/3 was the Neurovascular distribution revenue that we had was actually higher in the first quarter than it was in the fourth quarter, and that was slightly unanticipated. So -- and again, as we've discussed before, that has -- basically, distributor's margin, very low margin. So that weighed on the margins. And then the third factor, which was roughly 1/3 as well, was that we ended up kind of taking our inventories down, maybe a little bit lower than we had thought we would initially, and that had an absorption impact that rolls through the margins in the first quarter. So 1/3 mix, 1/3 Neurovascular distribution being higher than planned and 1/3 absorption. If you look now, going forward, what do the margins do from a sequential perspective from the first quarter to the second, second to the third, is really kind of 3 factors. One is, we expect that our value improvement programs and our cost-saving initiatives will continue to be enough to offset from a margin percentage perspective price, and that mix will be less of a challenge. So we think those kind of neutralize, if not, slightly more favorable. What also happens is, from a Neurovascular perspective, our Neurovascular revenue, the distribution revenue, the striker drops off quite a bit from Q1 to Q2 and then again from Q2 to Q3. And in those step-downs, we get a margin uplift from those. So there's roughly a 50-basis-point benefit from Q1 to Q2 and then another 50 basis points from Q2 to Q3, from just basically taking that distribution revenue down from roughly $36 million in the first quarter to almost 0 in the third quarter. So you get a margin benefit from that. And the third factor is, from an FX perspective, with the rates are -- where they are today, that helps a bit from a margin percentage perspective.

Michael N. Weinstein - JP Morgan Chase & Co, Research Division

Okay. I think that's clear. One last question, and I'll let others jump in. The -- as you get ready to launch the Lotus Valve in Europe, can you just talk about what your plans are from a distribution standpoint? Obviously, you've got a very strong Interventional Cardiology presence, but you haven't called historically on the cardiothoracic surgeon. So how are you preparing for that, and what are you going to do differently?

Michael F. Mahoney

Yes, certainly, we're not going to provide lots of detail on our commercial strategy. As you said, we have a large Interventional Cardiology sales team and we have a clinical sales specialist that we have, not only for our Atritech program, but also for our Lotus program. So we'll leverage our clinical sales team's instructional hires and also the commercial presence that we have across our Interventional Cardiology team to commercialize Lotus. Does that help?

Michael N. Weinstein - JP Morgan Chase & Co, Research Division

Yes.

Operator

Our next question in queue will come from Matt Taylor with Barclays.

Matthew Taylor - Barclays Capital, Research Division

I wanted to just touch on the constant currency guidance. Just was curious, I'm hearing a lot of moving parts around new products, has your expectation for contribution from the new products versus kind of the core business changed at all versus prior guidance?

Jeffrey D. Capello

Yes, that's a good question. So if you go back and you look at what we've laid out relative at Investor Day in terms of expectation, the contribution of some of the adjacencies that we've entered, I would say that our expectation has not changed. We still feel pretty good about the expected contributions. And those really start to kick in, in Q3, and then, in a bigger way, in Q4. Certainly, there'll be some puts and takes, but overall, we feel pretty good about the contribution of adjacencies in addition to the new products that have been developed internally, the Promus PREMIER launch, the continued rollout of INGENIO and the other countless new products that come out within the MedSurg business.

Matthew Taylor - Barclays Capital, Research Division

And then just real quickly onto the -- your launching and ramping here that you covered a little bit. Can we get more color on what the atrial appendage, given the data that you showed earlier in the quarter? And also, any color on maybe on the Asthmatx launch that you can give above and beyond what you talked about in the script would be great and your expectations there?

Michael F. Mahoney

Well, Ken, maybe you can provide some comments, additional mind on Atritech. So we had a nice sequential growth, year-over-year growth in Europe, with Atritech exceeding 30%. And we expect to file with the FDA in the second quarter. And we'll also be announcing that, hopefully, a late breaker here at HRS, the efficacy results of our PROTECT-AF trial. So, Ken, any other comments you want to make on Atritech?

Kenneth J. Pucel

Yes. I mean I would just say, just to reiterate, we were very encouraged by the PREVAIL data. It, to our thinking, goes a long way to resolving the concerns people had about safety of the device, particularly with new implanters showed comparable efficacy outcomes to our anticoagulation. Also, I just want to emphasize to everyone that when we do file with the FDA, it's not just the PREVAIL data, it's the totality of all of the date we have, what device, the pilot study, PROTECT-AF, the ASAP trial in contraindicated patients, as well as PREVAIL. And again, just to reiterate, as Mike said, we will be presenting the long-term follow-up data PROTECT-AF as a late-breaking trial at HRS, and that's going to be by far the longest experience that anyone's had in a large-scale randomized clinical trial with left atrial appendage closure.

Michael F. Mahoney

And with respect to -- yes, with respect to Alair, we had a few comments there in the script. We certainly want -- we're very optimistic about this program, and we're making steady progress. We yet don't have the final reimbursement numbers that we have, but we've seen sequential improvement. Our Asthmatx business grew about 70% in the first quarter. We're opening new centers. We're seeing the high renewal rates in terms of reordering rates amongst the physicians that are using it. We applied a grant today a Category I CPT code in the first quarter. And we continue to make efforts to drive a reimbursement strategy to open up this market. And we think a key -- the key deliverable will be our 5-year efficacy data that we'll present either late second quarter, early third quarter. And we are hopeful that will be a trigger to help unlock some of the reimbursement that's been clogging the channel for Alair.

Operator

Our next question in queue will come from Matthew Dodds with Citigroup.

Matthew J. Dodds - Citigroup Inc, Research Division

First thing on the U.S. stent market, it looks like the volumes, unless Medtronic has a big quarter, are going to be down about 10%. But I think you said in the commentary, stents per procedure might be off a little. So I just I wanted to see, a, why you think that might be? And what do you think -- what's happening with the volumes in the U.S.? Why are they still falling so fast?

Jeffrey D. Capello

So, Matt, it's Jeff. I'm not sure we would agree that the volumes are falling 10% from -- so exclusive of price, I think we would put that the PCI's probably down, probably kind of low- to mid-single digits. That's kind of our intelligence so far looking at what we track, what Abbott has tracked and, of course, we'll see what Medtronic reports. And price, obviously, is a negative on top of that. So we're more kind of low- to mid-single-digit PCI contraction year-over-year.

Matthew J. Dodds - Citigroup Inc, Research Division

And then how about the stents per procedure? That comment, is that something new?

Jeffrey D. Capello

No, I think we've started to see that about 6 to 9 months ago. And that was kind of a dynamic that kind of maybe midpoint last year, and it was kind of reflected in our assumptions going forward for guidance and for the market.

Matthew J. Dodds - Citigroup Inc, Research Division

And then, Jeff, one more thing for you. Given the high percentage of sales in Japan, the impact on the top line, why -- or is there an impact in the bottom line that you're covering or do you offset it through the P&L?

Jeffrey D. Capello

Yes, that's a good question. So we -- our hedging philosophy is to neutralize for FX. And so at any point in time, we are almost, pick a percentage, 90% hedged for the current year. And the next 12 months, depending on where you are in the year, the following 12 months, we're probably somewhere between 70% hedged and we're about 50% hedged for the third year. So when we see these types of dramatic changes in currencies like the yen, we're pretty much protected from an OI perspective. Now when we hedge operating income, we don't hedge at the revenue level. So you'll see fluctuations in our revenue, which is why the guidance comes down $150 million on the top line because we don't hedge the revenue. But it doesn't have a big impact from us -- for us from an operating income and an EPS perspective because we neutralize for that. You give up some of the upside, but you neutralize for the downside, which, in this environment, actually plays out pretty well for you.

Matthew J. Dodds - Citigroup Inc, Research Division

And are those hedges in -- all in the gross margin or are they also in other parts of the P&L?

Jeffrey D. Capello

The majority of them are -- run through the gross margin and some -- well, the impact hits you in kind of the gross margin and in some of the SG&A as well.

We'll take that question from Bruce Nudell with Credit Suisse.

Bruce M. Nudell - Crédit Suisse AG, Research Division

I guess we've heard some, I don't mean to be disrespectful, but surprisingly nice things about Lotus, and that people really like, kind of the stress-free implant experience. Could you just opine on -- is this going to be, in your view, I know you need other sizes and all and the rollouts, controlled that you don't have transapical right away? But in the transdermal segment, how do you view this product in terms of market share?

Michael F. Mahoney

Bruce, it's Mike. Thanks for your high expectations you had on the product, man.

Bruce M. Nudell - Crédit Suisse AG, Research Division

No, no, no. We've consistently heard very nice things from surprising sources, I'd say.

Michael F. Mahoney

Good. Well, why don't we first start off with Dr. Keith Dawkins who's on the phone. He was just at the Korea [ph] live event where Lotus was implanted live, so maybe he can make some comments.

Keith D. Dawkins

Yes. It's good to hear you surprised, Bruce, about a good product. Yes, I'm at TCT Asia Pacific and Seoul, and the first live Lotus Valve was done yesterday, no aortic regurgitation at all. And just a completely different experience compared with the competitor products. Early valve function, as you say, a relaxed procedure, predictable, retrievable and re-positionable. And I think the aortic regurgitation is the -- is really the Holy Grail. And you will have seen the SAPIEN XT results of ACC were 29.2% moderate and severe aortic regurgitation, which really, clinically, is completely unacceptable. So we're very excited about this product. And the operators that have now used it in the CE Mark trial in 4 countries, Australia, France, Germany and the U.K. have just been blown away, as have the core lab, the eco-core lab. And as you know, when you assess aortic regurgitation and compare products, it's important to use an eco-core lab, and some of the smaller players don't do that. So we are very excited and looking forward to discussions with the FDA, further discussions with the FDA around the IDE trial and commercializing after CE Mark in the back half of this year.

Bruce M. Nudell - Crédit Suisse AG, Research Division

And I guess my only follow-up is a small niggling question. How should we be thinking about revenue in the discontinued operations bucket for the rest of the year?

Jeffrey D. Capello

Yes. Bruce, it's Jeff. So as I said in responding to Mike's question on margins, we would expect that the distribution revenue to the Stryker would go from kind of the mid-30s down to -- which is what it was $35 million off the top of my head, in Q1 down, it's like $20 million in Q2, down to pretty much 0 in Q3.

Michael F. Mahoney

Tony, there seems to be a lot of interest in just looking at the queue. [Operator Instructions]

We'll take our next question from Kristen Stewart with Deutsche Bank.

Kristen M. Stewart - Deutsche Bank AG, Research Division

Just wanted to see if you guys would be willing to give just the S-ICD contribution in the quarter, just to try to better understand what the base kind of ICD business is doing.

Jeffrey D. Capello

Well, Kristen, we're not going to get in to kind of contributions from each of the product lines. As I think Mike pointed out in his comments, we had a very strong result for the first quarter at CRM, despite the fact that we weren't on the market much with the S-ICD device. So I think we'll probably leave it at that.

Kristen M. Stewart - Deutsche Bank AG, Research Division

Okay. And then just looking at the operating margins that you are now providing as well, I was kind of somewhat surprised by just how low the Rhythm Management margins were and they declined on a year-over-year basis, looks like now they're at 12%. Can you maybe just, I guess, explain why margins were down so much year-to-year and kind of where do you see those margins kind of going since you are substantially below kind of where we would expect Medtronic and St. Jude's margins to be? What are going to be the key initiatives do you have to basically moving that up? I'm not sure how much of an impact the S-ICD has with that on a year-to-year basis.

Jeffrey D. Capello

Yes, it's a very good question, Kristen. So as you have noticed in the earnings release, we have -- as we've discussed, we've moved towards these global business segments. And now we will be disclosing the operating income profitability of Cardiovascular, Rhythm Management and MedSurg on a regular basis. I'm going to take you back and answering your question to the Investor Day. We clearly had outlined a game plan to improve our overall company operating margins by at least 600 basis points over the next 5 years. And frankly, the Rhythm Management business was a big piece of that. The reason why they are lower than we'd like them to be, and perhaps some of our competitors, one factor, obviously, has been the market declines and some of the historical issues we've had. But the second issue, which is pretty important is, we are investing aggressively in that business, both the Cameron acquisition, the Rhythmia acquisition, the Atritech acquisition have all added significant investments in research and development and commercial operations. So that's important to understand. Now why does it change? Certainly, what you're seeing now is kind of the weight of all of those investments and not much of the return. So as we finish the R&D programs and as we get through kind of the commercialization investment and the revenue starts to take off in the back half of the year and into '14, you're going to see a pretty dramatic change in the profitability because right now it's weighed down by all those investments and not much revenue. And into the back half of this year, starting in the back half of this year and into next year, you get the release of some of that investment because we're through some of those programs, and then you start to get the revenue at pretty good margins. So that in combination with the revitalized portfolio of our core business, which frankly is doing very well if you look at kind of our results relative to at least St. Jude's on the core CRM side, we had a pretty good quarter relative to them. And then you look at our differentiated platforms, S-ICD, WATCHMAN getting into higher growth markets. The EP space is a focus for us with the Rhythmia acquisition and all of the investment we're doing at EP, as well as all the productivity initiatives. In the second quarter, we announced -- of '11, a restructuring program. And at the end of January, we announced an expansion of that program. A lot of that benefit from a cost perspective flows through the Rhythm Management business. So we expect to be able to grow that business, and with these new acquisitions kind of taking off in the back half of the year and next year to lead a significant operating margin improvement. So as you come back to kind of the 600 basis points of overall company margin improvement, we would expect that the CRM -- the Rhythm Management segment would benefit disproportionately from those programs and from those activities.

And just real quick and last on the WATCHMAN Device. Do you guys anticipate having to go back before a panel or -- for approval?

Michael F. Mahoney

Hey, Ken, do you want to comment on that?

Ken Stein

Yes. Well, we're prepared to go to a panel if we have to, but I'm not going to speculate on what the FDA is going to decide in that regard. Obviously, the device has already been through a panel previously that did recommend approval.

Our next question in queue will come from Larry Biegelsen with Wells Fargo.

Lawrence Biegelsen - Wells Fargo Securities, LLC, Research Division

One on the P&L, one product question. Similar to a question that was asked earlier on R&D, Jeff, can you talk about the SG&A spending from an absolute standpoint? Last year, it actually trended down through the year. And second, on royalties, it was a little bit higher than we expected this quarter. Do you expect that to trend down as we saw last year? And then I just have one follow-up product-related question.

Jeffrey D. Capello

Okay. Well, so from an SG&A prospective, you're right, it did trend down as we went through the year in 2012. We do expect it to trend up slightly in Q2 and Q3 based on some of the commercialization investments that we're making to bring the TAVR product to market, which we expect to hit the market in the back half of the year; the Vessix product to the market; as well as a unit kind of rollout of Promus PREMIER in Europe now, and in the back half of the year, for the U.S. So we expect it to uptick slightly in Q2s and Q3s from a percentage perspective, so hopefully that's helpful. So that's from an SG&A perspective. From a royalty perspective, we do expect it to trend down in the back half of the year because what happens is the percentages, those tiers and the royalty arrangements, where you get to a certain tier of revenue, and the percentage actually drops. So if you sell more, the percentage goes down. As a result, the overall average percentage drops down as you go through the year. And that's consistent with pretty much every year.

Lawrence Biegelsen - Wells Fargo Securities, LLC, Research Division

That's very helpful. And then on the product question, another one on the Lotus Valve. Like Bruce, we've also heard positive things on the valve. So two-part question. One is, can you remind us of the rollout plan on the different sizes? And second, in the first study, there was a relatively high pacemaker rate, but it was a very small study, 4 out of 11. Do you guys think that you guys have addressed that and we would expect to see the pacemaker rate probably in line with other self-expanded transcatheter valve, such as a core valve pacemaker rate?

Michael F. Mahoney

Yes, Keith, you can make some comments. What we'll be shooting for CE Mark approval will be 2 valve sizes, the 23 and the 27 that you're hearing the results on, and we'll continue to expand the portfolio of valve sizes over the future. With respect to the pacemaker rate, we'll be presenting some data at the upcoming PCR. But in general, we would assume that the pacemaker rate would be in line with the core valve product.

Keith D. Dawkins

I'll just add, Larry, as you said in REPRISE I, that was a 11-patient study and there were 4 patients who have paced, but 2 of the pacemakers had not been used. And then, as Mike says, in EuroPCR in the late-breaking trial, we'll present the 30-day data from the first 60 of the 120 patients in REPRISE II to the CE Mark trial, and that will include the pacing data. It's not strictly a self-expanding valve, just to correct you there. It's not the same as a balloon expandable valve or a self-expanding valve. It's a hybrid valve. It's between one and the other.

Our next question in queue will come from Brooks West with Piper Jaffray.

Brooks E. West - Piper Jaffray Companies, Research Division

I wonder, Mike, if I could steer you back to the emerging markets, specifically the BRIC comments, can you talk about the scale of that business? And then can you talk about kind of the key product mix that's driving growth there?

Michael F. Mahoney

Sure. Within our BRIC markets, we continue to increase, not in dramatic ways, but we continue to increase the percent of the overall mix of revenue for BSC from BRIC. Historically, we've been at 3%, we moved up to 4%, now we're more approaching 5%. So it certainly is an important growth driver for us, and we expect to continue that 35% growth throughout the planning period here. I won't go through each country. We're very strong in Brazil. We're getting much stronger in China. We're building solid bases of business in India and Russia. And most often, our Interventional Cardiology, Endoscopy and Peripheral businesses are our large contributors of growth and operating income to those regions, those 3 business units. So we're obviously advancing all of our business units, but those 3 provide the greatest contribution.

Brooks E. West - Piper Jaffray Companies, Research Division

That's helpful. And then just 2 quick ones for Jeff. Can you speak to pricing trends in DES? We've been picking up some signals that maybe the pricing headwinds, especially in the U.S., had been getting worse? And then would you say anything on your exposure to the pelvic floor litigation that's been talked about recently?

Jeffrey D. Capello

Yes. So on the pricing trends, I would say that the -- we weren't encouraged by the pricing -- we -- encouragement had happened to us in terms of pricing in the first quarter. So we've been very conscious and have conceded some share historically to kind of walk away from situations where the price was not commensurate with the value we were delivering. And we'll continue to kind of be pretty disciplined, and I think that is actually getting slightly better for us. So I'd say pricing -- so obviously, you make that comment with a little bit of hesitation because you don't know what's going to happen, but we were encouraged by what we saw in the first quarter from a pricing perspective.

Brooks E. West - Piper Jaffray Companies, Research Division

And then on the -- just on the pelvic floor litigation?

Jeffrey D. Capello

Yes, like all litigation matters, we wouldn't comment on that specifically.

Operator

Our next question will come from Jose Haresco with JMP Securities.

Jose T. Haresco - JMP Securities LLC, Research Division

Let's see here, just following up on the pricing. Do you have -- on DES here in the U.S., do you have a sense of what factors could be leading to a better environment on the pricing side here in the U.S.? And can you contrast that with what you're seeing in Europe?

Jeffrey D. Capello

Well, I'd say certainly product differentiation is pretty important, right? If you back up 1 year, 1.5 years ago, you had 2 products that are completely identical in PROMUS and XIENCE, just different boxes. And so now, we certainly feel that our PROMUS Plus stent in the U.S. is better than anything on the market, and we're marketing it as such. And when we come out with Promus PREMIER, we think that's another step forward from a product prospective. So -- and we intend to sell the product for its value, and so we think that's what's driving some better comparables from a pricing dynamic perspective. Europe's a little bit more of a challenge given the macro factors and the austerity measures, that pricing erosion is a little higher upper-single digit, if not kind of low 10% over the board than that, and that's just all driven by the austerity measures.

Jose T. Haresco - JMP Securities LLC, Research Division

A follow-up question on another subject. You mentioned you slightly picked up some share in the de novo implants in the first quarter. Is that a sustainable trend? And could you point at 1 or 2 things that are leading to that?

Michael F. Mahoney

On the de novo front, we launched a new platform in 2012, the INCEPTA-ENERGEN platform, that has differentiated features and price points based on the customers' objectives, and that continues to make good progress. And there are many compelling features on it, the top 3: One, is we still believe it's the small, thinnest device that patients enjoy; secondly, the longevity of the device and our significant warranties to back that up; and third, the lead reliability. So those are 3 features that we think are differentiated and we believe are helping to contribute to some of the positive share gains we're seeing in de novo ICD implants.
