Good day. My name is Ian, and I will be your conference operator today. At this time I would like to welcome everyone to the Fourth Quarter Earnings Call. All lines have been placed on mute to prevent any background noise. After the speakers' remarks, there will be a question-and-answer session. Thank you. Mr. Jonathan Doros, you may begin your conference. Jonathan Doros - Symantec Corp.: Good afternoon. Thank you for joining our call to discuss our fourth quarter fiscal year 2017 earnings results. We've posted the earnings materials and prepared remarks to our Investor Relations Events webpage. Speakers on today's call are Greg Clark, Symantec's CEO; and Nick Noviello, Executive Vice President and CFO. This is a live call that will be available for replay via webcast on our website. I'd like to remind everyone that all references to financial metrics are non-GAAP, unless otherwise stated. We provide year-over-year constant currency growth rates in our prepared remarks for revenue. During the call we may speak to growth adjusted for acquisitions metric, which includes prior period non-GAAP revenue from acquisitions adjusted for Symantec's accounting policies including quarterization. All non-GAAP revenue and expenses exclude the impact of Veritas, however the continuing operations deferred revenue on the balance sheet includes a portion of Veritas deferred revenue from Symantec and Veritas bundled contracts entered into prior to operational separation. The Veritas deferred revenue from those contracts will amortize into discontinued operations. As a result implied billings growth calculated from the change in deferred on the balance sheet will not be representative of stand-alone Symantec's performance as it will include an impact from Veritas. Please note, non-GAAP financial measures referenced during this call are reconciled to their comparable GAAP financial measures in the press release and supplemental materials posted on our website. We believe our presentation of non-GAAP financial measures, when taken together with corresponding GAAP financial measures, provides a meaningful supplemental information regarding our operating performance for reasons discussed below. Our management team uses those non-GAAP financial measures in assessing our operating results, as well as when planning, forecasting and annualizing future periods. We believe those non-GAAP financial measures also facilitate comparisons of our performance to prior periods and to our peers and that investors benefit from understanding of the non-GAAP financial measures. Non-GAAP financial measures are supplemental and should not be considered a substitute for financial information presented in accordance with GAAP. Today's call contains forward-looking statements based on the environment as we currently see it. Those statements are based on current beliefs, assumptions and expectations, speak only as of the current date and, as such, involve risks and uncertainties that may cause actual results to differ materially from our current expectations. Please refer to the cautionary statement in our press release for more information. You will also find a detailed discussion about our risk factors in our filings with the SEC and, in particular, on Form 10-Q for the quarter ended December 30, 2016. We would like to remind everyone that we'll be hosting a Financial Analyst Day on June 8. Further details are available on our Investor Relations website. And now, I'd like to introduce our CEO, Greg Clark. Go ahead Greg. Gregory S. Clark - Symantec Corp.: Thank you for joining us. Fiscal 2017 was a transformative year at Symantec with substantial improvement across the entire company. Fiscal 2018 marks the second half of our execution plan to fundamentally transform Symantec's enterprise and consumer businesses addressing both revenue growth and profitability. Today, we announced our Q4 fiscal year 2017 results. And we're also raising our fiscal 2018 EPS outlook to $1.75 to $1.85. I will recap our fourth quarter and fiscal year 2017 results, update you on our progress within Enterprise Security and Consumer Security segments, discuss our transformation and cost savings commitments, and our CFO, Nick Noviello, will provide more details on our financial results and fiscal 2018 outlook. Beginning with Q4, our results demonstrate strong and consistent execution relative to our expectations. During the quarter, we saw further evidence that our investments and commitments to innovation are distinguishing us as the leader in cyber security for the cloud generation. Let me highlight a few key areas from the quarter. Our overall Q4 business activity was strong and consistent with our expectations. And within Enterprise Security, we saw a faster than expected increase in mix towards cloud subscription and virtual appliances. We believe this product mix shift is a positive for our business both financially and strategically, is a proof that our customers are designing Symantec into their future cloud security architectures. Enterprise Security profitability has improved dramatically with Q4 fiscal year 2017 operating margins up 17 points year over year. Consumer Security revenue growth performed better than our guidance, and LifeLock came in above our revenue expectations as well. Overall, we continued to perform ahead of plan on our cost efficiencies and synergies. Total company margins were at the high end of our guidance. And as a result, we delivered EPS at the high end of our guidance, excluding LifeLock. Now turning to our Enterprise business, we are combining best of breed product innovation with unmatched scale. This is leading to significant competitive advantage and differentiates us in the market as the leading cyber security provider for enterprises. During the fourth quarter, business activity was strong. We are pleased to report Enterprise Security grew 2% organically in the quarter. The business activity of our Blue Coat products were in line with our expectations at above-market growth. And we hit a big milestone in Q4, as we have achieved feature parity between our network products delivered through an appliance and its corollary in the cloud. We now have the leading software elements across relevant deployment methods: appliances, virtual appliances, and pure cloud. During the quarter, we doubled the number of cloud proxy competitive wins versus our next largest cloud competitor. And we are pleased that we saw accelerating demand for cloud and subscription solutions. Selling more cloud solutions is a positive indicator for future success. This has an effect on end period revenue with the benefit of increased deferred revenue. The Blue Coat subscription offerings are now approaching $100 million revenue run rate, growing 67% year on year in the fourth quarter with business activity more than doubling on an annualized basis. Now on to Consumer Security results for Q4 fiscal year 2017; Consumer Security exceeded the high end of our revenue guidance on an organic basis, and LifeLock performed above revenue expectations with strong underlying growth metrics. LifeLock renewal rates increased year over year and cumulative ending members were up 8% year over year. This is an impressive result amidst the significant acquisition and integration activity. Moving to the full year fiscal 2017, the results show improving revenue performance and delivered ahead of plan on operating efficiency, while we are, at the same time, integrating our transformative acquisitions. Nick will cover the full year fiscal year 2017 details in his remarks. Now let me turn to the strategic progress we are making in Enterprise Security. Our Integrated Cyber Defense Platform is clearly resonating with customers. We believe our Integrated Cyber Defense Platform provides the security reference architecture for the future of IT environments whether on premise, software defined or in a pure cloud delivery model. The strength of our platform begins with a strong commitment to leading cyber defense intelligence. As we have commented on previously, the integration of Blue Coat and Symantec threat intelligence has created a differentiated lens into the threat landscape. An example of our artificial intelligence adding significant value with this data is now resulting in blocking an additional 3.2 million attacks every day. We expect more advancements from our artificial intelligence as we further integrate our network and endpoint data. Our Integrated Cyber Defense Platform ingests this threat intelligence and combines it with robust integrated functionality across our user, web, information, and messaging solutions. Turning to a representative customer example, recently one of the world's largest food and drug retailers with over 60,000 users embarked upon an initiative to move to the cloud and upgrade their security infrastructure. Our sales team moved the conversation with the customer from speaking about a combination of point solutions to articulating the benefits of our Integrated Cyber Defense Platform. We delivered a solution that improved the customer's security posture and reduced their expense. Given the increased Symantec footprint, this customer is now paying approximately 60% more to Symantec but reduced their overall security spend by an estimated 25% and took a major step forward in their security posture. We expect these type of win-win opportunities to be commonplace as companies are looking for integrated platforms as they struggle with technology sprawl and runaway costs due to isolated point vendors. Now let me highlight our leadership in cloud security. In order for the enterprise customer to take advantage of the cloud, security solutions must be incorporated that reduce the risks inherent in the cloud generation. All of our major solutions are now delivering in the cloud and designed for the new risks our customers are facing. For example, we have an industry-leading approach to securing cloud applications. We have combined cloud proxy, CASB, Data Loss Prevention, and multi-factor authentication into one complete offering that addresses these new risks. We believe we are the only company that has all of these major components and we'll enjoy this position for the foreseeable future. When compared to the alternatives of an internal IT shop procuring and integrating multiple solutions from point vendors, we are an obvious choice. In Q4 we saw a substantial traction with our entire cloud security portfolio. As an example of our success, during the quarter we won a large deal at a major technology services company that is undergoing a cloud transformation. The customer took the first steps in adopting this platform for their internal environment with the purchase of our cloud proxy and DLP. This was a highly competitive win and a massive endorsement to our strength in cloud security given how cloud-centric IT services organizations are today. We see many deals in the pipeline that are similar in nature. Turning to our endpoint security solution, endpoint security is a key component of our platform and its success has resulted in customers cross buying additional components of our cyber defense platform. In Q4, we saw continued success with SEP 14 from both a product and sales standpoint. SEP 14 detection rates have improved 26% compared to SEP 12. Competitive wins are increasing and SEP 14 has not witnessed a significant technical loss. For example we replaced a major competitor at a large financial services company. There were multiple drivers of the win including SEP integration with ProxySG and our superior machine learning capabilities. The competitive landscape is turning in our favor with a leading-market share endpoint vendor removed from a third party endpoint leadership quadrant as well as smaller endpoint providers experiencing some recent significant missteps. Overall we see signs of increasing win rates and expect renewal metrics to improve over the medium term. In addition, Endpoint Detection and Response, EDR, is an important part of the endpoint market that is garnering attention from customers. The next release of our converged endpoint plus EDR solution is launching soon. As we introduce this new version of converged endpoint plus EDR into our installed base, we expect to have a similar impact to the current point EDR solution vendors as SEP 14 is having on point machine learning and exploit prevention vendors. For example, during the fourth quarter we closed a nearly 180,000 endpoint win with a large IT services company that included our EDR and endpoint security. The customer was overwhelmed with the high volume of alerts across 40 countries and was seeking to consolidate their endpoint security to a single vendor. We won due to our strong technology and single agent architecture. This win involved replacing two competitors out of our customer's endpoint environment. We have made strong progress in EDR and are pleased with our first year in the market closing approximately 600 customers. We believe, given our rapid adoption, we are already a meaningful player in the EDR market one year after launch. This is an example of our competitive advantage enabled by our platform. In summary on endpoint progress, the power of our platform improves the security posture of our customers while enabling them to drive down their overall security cost per employee. The combination of cloud proxy, CASB, DLP, and multi-factor authentication enables the cloud generation. With SEP 14, we are now the leading next generation endpoint provider and will further extend our leadership with the introduction of the converged endpoint and EDR. Now onto our Consumer Security segment, the acquisition of LifeLock was a catalyst that expanded the business on to a new market category of Consumer Digital Safety. We believe digital safety increases our addressable market to an estimated $10 billion growing in the high single digits. We have expanded our value proposition by offering a comprehensive digital safety solution that delivers more value to the customer than PC malware protection alone and protects all aspects of a consumer's digital life including their information, identities, devices, homes and families. In addition, we now have a much larger demand generation budget for enhancing our brand and driving new customer acquisitions. We expect this competitive differentiation will fuel sustainable long-term growth in new customers and retention metrics. During the quarter we are already seeing signs that the strategy is working. Norton results were better than our outlook driven by renewal metrics and new products such as mobile solutions and privacy technology. We see a significant opportunity to deliver more value to our loyal customers which we will expand upon in more detail at the Financial Analyst Day. At a high level, there are multiple growth drivers that underpin our digital safety strategy. Let me outline the major components. First, leverage our larger demand generation. By combining Norton and LifeLock we have substantially increased our demand generation engine that can inform the market of our expanded value proposition. Our combined demand generation spend nearly triples compared to Norton stand-alone, and we expect it will provide greater economies of scale. For example, we recently rolled out a co-branded marketing campaign by leveraging LifeLock's existing paid TV and radio advertising spend. Second, transitioning to a digital safety offering. Another lever for growth is transitioning our loyal Norton customer base to our digital safety bundle We began our journey to digital safety by cross selling new offerings such as Wi-Fi privacy and our upcoming home IT security and next generation parental control solution, Norton Core. We have already begun the preliminary phases of cross selling Norton into the LifeLock base through a referral process. And in June, we plan to begin to cross-sell the LifeLock and Norton bundle, which we believe has potential to drive upside to our current outlook. As a reminder, identity protection customers pay 2 to 3 times more for protecting their identity than the average selling price of PC malware protection. We were purposely measured in our cross-sell launch of LifeLock into the Norton base to ensure our internal systems and processes were tightly aligned. Moreover, with approximately 50% of the Norton installed base outside the U.S., international expansion of the digital safety bundle is a large opportunity. Third, mobile security. Mobile users increased 50% year over year driven by both Android and iOS growth. In April, we signed an agreement with a large international telco to deliver Norton Mobile protection for their customer base, which is a new route to over 43 million wireless subscribers. We are also seeing an uptick in demand of mobile private VPN due to recent legislation that permits ISPs to share customers' internet activity. Finally, Norton Core, which has the potential to be a significant growth driver. Norton Core is an exciting extension to our digital safety platform. We are seeing continued strong reception from partners and industry participants. We expect the combined consumer business to reach growth adjusted for acquisitions by the first half of fiscal 2018. We plan to accomplish this while maintaining industry leading profitability, which provides us with the flexibility to continue investing in driving long term growth in our Consumer Digital Safety business. Turning to recent developments related to our website security solution. As you may be aware, in late March, Google put forth a proposal that, if implemented, would introduce major changes to the processes and operations that are standard across our industry, including our Certificate Authority business. Since that time, we've been engaged in conversations with Google, Mozilla, and other members of the CA community to seek input on our counter proposal that we believe minimizes business disruption for our customers and improves trust in Symantec's CA business. We believe we will find a mutually agreeable path forward that is in the best interest of our customers, and we expect discussions around our proposal to continue and have factored our current expectations around this headwind into our financial outlook. Now, I would like to address the transformation of the overall Symantec business and our operational commitments. We indicated there was a strong industrial logic to our transformation. Exiting fiscal 2017, we believe this industrial logic is materializing across the business. Last June, we committed to a set of cost savings and synergies. We're achieving these savings at a faster pace than originally anticipated and we are ahead of plan exiting fiscal 2017. Exiting fiscal 2017, the financial profile of Symantec has substantially improved from what would have been the picture not even a year ago. For example, Enterprise Security operating margins improved from 5% in fiscal year 2016 to 13% in fiscal year 2017 and we are forecasting exiting fiscal year 2018 with over 30% enterprise operating margins. Fiscal 2018 begins the second half of our execution plan to fundamentally transform Symantec across both revenue growth and increased profitability. As we exit fiscal year 2018, at the highest level, we expect organic revenue growth for each of our segments, and total organic revenue growth for the company in the mid-single digits with market leading operating margins, in Enterprise Security above 30% and in Consumer Security above 40%. We are entering the year with significant operational improvements in our go-to-market processes and have simplified the demand chain and programs to our partners reducing substantial complexity across the business. We have made substantial transformational changes in our Enterprise Security segment related to SKUs, price lists, partners and systems. And today, we have a very capable and proven team that can navigate integration complexity and continue to focus on disciplined operational execution. We have combined two quota carrying sales forces thus increasing our productive sales capacity. From the close of the Blue Coat transaction through the end of fiscal year 2017, we effectively maintained the equivalent of 2 sales reps per named account, with divided territories. Over the last nine months, we have worked to align our sales capacity more efficiently. We are confident that our efforts are already translating to results, however, we believe it is prudent to begin the fiscal year 2018 Q1 with modest close rate assumptions, allowing for additional sales capacity to take effect. In summary, the new Symantec has established significant competitive differentiation, which allows us the financial flexibility to maximize our investment in cyber security, which greatly benefits our customers, employees and shareholders. The industrial logic around the Symantec and Blue Coat combination is stronger than ever, and we are combining leading product innovation with unmatched scale, which in our view, is leading to significant competitive advantages. The Integrated Cyber Defense Platform is resonating with customers and the opportunities to significantly expand our wallet share are materializing. We have transformed our Consumer business from PC malware protection to Consumer Digital Safety. This brings significant competitive differentiation and we expect will fuel sustainable long-term growth. We are forecasting that our Norton customers will purchase LifeLock, hence, returning the consumer business to organic growth. We are on track to deliver long-term sustainable growth with leading profitability across both our Enterprise Security and Consumer segments. And we are on track with our expectations to exit fiscal 2018 with organic growth accelerating into the mid single digits with total non-GAAP operating margins over 35%. Now, I will turn the call over to Nick to provide more financial detail. Nicholas R. Noviello - Symantec Corp.: Thank you Greg and good afternoon everyone. Today I will provide an overview of our fourth quarter and full year fiscal 2017 financial results. I will give you context to our segment performance and our cost savings, synergies and the substantial integration, transformation and business process changes we are executing as we round out fiscal year 2017 and enter fiscal year 2018. And I will review with you details around our fiscal year 2018 and first quarter fiscal year 2018 financial outlook. We have also made additional details including reconciliations of GAAP to non-GAAP measures such as amortization of intangibles and stock based compensation available in our CFO commentary, which is posted on our Investor Relations website. Before I review our results, I would like to remind you that our Q4 and fiscal year 2017 financial guidance provided on February 1 did not include a contribution from the LifeLock acquisition, which subsequently closed on February 9. In our prepared remarks last quarter, we stated that we expected LifeLock to contribute just under $100 million of revenue for the stub period in our Q4, and be $0.01 dilutive to Symantec earnings per share. Let me start with an overview of our Q4 financial results. Our fourth quarter non-GAAP revenue was $1.176 billion, up 36% on a constant currency basis. For the stub period, LifeLock contributed $100 million to revenue during the quarter, which was slightly better than our expectations. Excluding LifeLock, revenue was $1.076 billion compared to our guidance of $1.070 billion to $1.090 billion. While business activity was consistent with our expectations for Q4, we saw the subscription mix within our Blue Coat products above expectations, which had an impact on end period revenue in the quarter. I will expand upon this later in more detail. Overall organic revenue performance was approximately flat, excluding revenue from the Blue Coat and LifeLock acquisitions, with better than expected results in Consumer Security, and growth in Enterprise Security. This is an improvement of 6 points compared to the same period in the prior fiscal year. Non-GAAP operating margin for the fourth quarter was 27%. Excluding LifeLock, our operating margin was 29%, at the high end of our guided range of 27% to 29%. Operationally, our strong non-GAAP operating margin was driven by continued execution against our cost savings initiatives and synergies. Fully diluted non-GAAP earnings per share was $0.28 and included a $0.01 headwind from LifeLock as we anticipated. Excluding LifeLock, fully diluted non-GAAP earnings per share was $0.29, at the high end of our $0.27 to $0.29 guidance range. GAAP earnings per share reflects two elements that were not incorporated in our prior guidance. First, our preliminary valuation of LifeLock, and the related purchase price adjustments, such as revenue and intangibles, and other items we do not include in our non-GAAP earnings. And second, stock based compensation expense, relating not only to LifeLock, but also our alignment of our performance based executive compensation with shareholder interests. Fully diluted shares outstanding increased by 5 million shares to 663 million shares relative to our guidance of 658 million shares, due to the impact from our convertible notes, driven by increased share price and the timing of our share repurchase program. Please see the dilution tables posted to our Investor Relations website where you can see the impact to diluted share count from the convertible notes at various stock prices. Finally, cash from operations during the quarter was $353 million. Now let's review our operating segment performance for Q4 in a bit more detail; first, I'll review the performance of Enterprise Security. Our Enterprise Security segment non-GAAP revenue was $689 million and grew 49% year over year. Excluding acquisitions, Enterprise Security organically grew 2%. Enterprise non-GAAP operating margin was 16%, up 17 points year over year. As Greg stated, we believe our Integrated Cyber Defense Platform will improve the security posture of our customers and considerably reduces their per user cyber security costs, while at the same time increasing our annual wallet share per employee. As we evolve our business to selling integrated solutions, it will become more challenging to delineate growth by each product line on a quarterly basis. That said, we are clearly seeing an improvement in our underlying business. Let me provide three examples of products within our Integrated Cyber Defense Platform. During the fourth quarter, endpoint security grew in the low single digits year over year. .cloud, our SaaS based email security grew over 20% year over year and total email has now inflected to growth of 7%. For the 11 months through the end of our fiscal year, revenue related to Blue Coat products is up 10% year over year. At our Financial Analyst Day, we will discuss metrics that are aligned to how we are managing the business going forward, with examples to show how we are increasing wallet share per protected user through cross buying of our platform, while enabling our customers to improve their security postures through use of our products. Now turning to Consumer Security, our Consumer Security segment non-GAAP revenue for Q4 was $487 million and grew 21% year over year. Non-GAAP operating margin was 42%. Excluding LifeLock, Consumer Security was down 3%, which improved sequentially from the third quarter and versus our guidance of down 4% to down 3%. The improved revenue performance was mainly driven by continued improvement in Norton renewal metrics and to a lesser extent a tailwind from new offerings. LifeLock contributed $100 million to revenue which was higher than our expectations for the stub period. The underlying LifeLock metrics were strong and we have included a summary in the CFO commentary for your review. Now turning to a summary of fiscal year 2017, overall, fiscal year 2017 was a year of important change for our business. As Greg indicated, we are driving significant integration, transformation and business process change across the company, and balancing financial performance as we do so. From a financial perspective, we performed well in fiscal 2017 across all metrics. On our last earnings conference call, we narrowed our fiscal year 2017 currency adjusted revenue growth to the high end of our previous range and raised our non-GAAP earnings per share guidance range, despite headwinds from foreign currency and fully diluted share count. Fiscal year 2017 revenue excluding LifeLock was $4.063 billion, up 12% on a constant currency basis. Revenue was $4.163 billion including the stub period of revenue contribution from LifeLock. Organic revenue growth, excluding Blue Coat and LifeLock, was down just under 3% compared to our original fiscal year 2017 guidance of down 4% to down 1%, and our performance in fiscal year 2016, down 5%. On an organic basis, Consumer Security revenue was down 5%, within our original fiscal year 2017 guidance of down 3% to down 6%. On an organic basis, Enterprise Security revenue was down 1% compared to our original fiscal year 2017 guidance of down 2% to flat. Non-GAAP operating margin excluding LifeLock was 29%, consistent with our prior guidance. We completed the year with over $300 million of run rate cost savings and integration synergies, ahead of our plans. Including LifeLock, non-GAAP operating margin remained at 29%. Non-GAAP EPS was $1.18, including a $0.01 headwind from LifeLock, which is an increase of 15% year over year and above our original guidance of $1.06 to $1.10 provided in May 2016. Cash flow from operations for the full year was negative $220 million but included $887 million in cash tax payments related to the sale of Veritas and $141 million of restructuring and separation payments. With respect to our cost savings initiatives and acquisition integration synergies, on prior calls, we discussed that our total cost savings initiatives are comprised of $400 million in net cost efficiencies on the Symantec business and $150 million in Blue Coat cost synergies to be achieved by the end of fiscal year 2018. In addition, at acquisition announcement, we communicated $80 million of cost synergies for LifeLock by fiscal year 2020, $30 million of which we expect to be achieved by the end of fiscal year 2018. As of the end of fiscal year 2017, we have achieved over $300 million of the $550 million in net cost efficiencies and Blue Coat synergies, which is faster than our original plan. We are also tracking well to achieve the LifeLock synergies of $30 million this year and $80 million by fiscal year 2020. Now turning to balance sheet and capital allocation, as of March 31, we had $4.3 billion in cash and short-term investments and $8.3 billion in gross debt including $1.75 billion of convertible notes. We expect to complete our $500 million accelerated share repurchase before the end of our fiscal first quarter and have $800 million remaining on our current repurchase authorization. Now let me provide you context on how we are entering fiscal year 2018. We have fundamentally transformed both our Enterprise and Consumer Security businesses and are now the largest pure-play cyber security company. Our Enterprise Security business is positioned with a robust and Integrated Cyber Defense Platform that increases the return on investment our customers realize from their security spend. The acquisition of LifeLock was a catalyst that enabled our Consumer business to expand into a new market category of Consumer Digital Safety. With respect to our financial outlook, I want to acknowledge that given the two acquisitions and all of the integration, transformation and business process changes we are executing, investors' financial models need to be updated. We are giving you as much information on this call as we can, and expect to use our Financial Analyst Day to further give you context on the drivers of the financials for each of our business segments and the overall corporation. Let me start with the full year, then provide our first quarter outlook. Further detail and GAAP to non-GAAP reconciliations and guidance are available in the CFO commentary. For the full year, we expect revenue to increase to $5.1 billion to $5.2 billion at guided rates, which is approximately 3% constant currency growth adjusted for acquisitions at the midpoint. We have incorporated in our guidance an expectation of a further shift to subscription in our Blue Coat network products versus fiscal year 2017, which reflects the recent increase in customers choosing our cloud offerings. This shift benefits future visibility to revenue and end year deferred revenue and cash flow. End year revenue from business moving to subscription will naturally be lower. We have also incorporated in our guidance our revenue expectations for our website security business due to the ongoing dispute with Google and the uncertainty it has created for customers. From a seasonality standpoint we expect the mix of our $5.1 billion to $5.2 billion of revenue to be weighted to the second half of the fiscal year, with about a 2 point shift from the first half, second half revenue mix we saw in the base Symantec business in fiscal year 2017. We believe this is reasonable, given the substantial transformation and business process changes we made in our Enterprise segment at the beginning of the fiscal year. In Consumer, we are launching our digital safety offerings, which are subscription offerings generated by our Norton and LifeLock teams. The combination of these actions in Enterprise and Consumer set us up extremely well to realize fully the value propositions of our transformative acquisitions. That said, the benefits to revenue will accrue later in the fiscal year, as all of the changes take root. For fiscal year 2018, we expect Enterprise Security growth adjusted for acquisitions of 3% to 5%, and Consumer Security growth adjusted for acquisitions of 1% to 3%. We expect that Consumer Security will show growth adjusted for acquisitions in the first half of the fiscal year. As Greg indicated, we expect the company to be exiting fiscal year 2018 at a revenue growth rate in the mid-single digits. We expect non-GAAP operating margins for fiscal year 2018 of 36% to 37%, up 8 to 9 points in constant currency versus fiscal year 2017. We exited fiscal year 2017 ahead of plan on our cost savings and synergy commitments, and expect to maintain our cadence in fiscal year 2018. We remain on track to exiting fiscal year 2018 with our cost savings and Blue Coat synergy programs largely complete. As it relates to the LifeLock synergies, we remain on plan to achieve the $30 million in synergies we committed to by the end of fiscal year 2018 and the $80 million by the end of fiscal year 2020. We expect non-GAAP EPS of $1.75 to $1.85 for fiscal year 2018, which is an increase from our prior guidance of $1.70 to $1.80, and up 52% to 61% versus fiscal year 2017 in constant currency. We expect a non-GAAP effective tax rate of 29.5%, up 50 basis points from fiscal year 2017 and driven by our mix of business. We expect fully diluted weighted average shares outstanding of approximately 675 million, up from 645 million in fiscal year 2017 and driven by increased share price and its impact on our convertible notes and options. We have not built substantial share repurchases into our share count estimates as our focus, from a capital allocation perspective, is on debt reduction. We plan to pay down a portion of our debt outstanding in fiscal year 2018. We have repaid $810 million of pre-payable debt so far this quarter and expect to retire our $600 million bond due in June. We also continue to maintain our regular quarterly dividend. Before I turn to our first quarter outlook, I would like to discuss the progression of our fiscal 2018 outlook. In June 2016 when we laid out our fiscal year 2018 EPS guidance of $1.70 to $1.80, the euro was trading at $1.13 and our underlying share count assumption was 585 million, which implied fiscal year 2018 non-GAAP net income of approximately $1 billion. Our fiscal year 2018 guidance today implies substantial non-GAAP net income improvement versus that initial estimate. At the same time, the euro has depreciated 5% causing an incremental $0.05 headwind to that guidance. Our share price has appreciated by approximately 70%, resulting in approximately 35 million shares of dilution from our convertible debt. The considerable share price appreciation also resulted in our share repurchase program retiring less shares than we had previously anticipated. And in addition, we reallocated a portion of the previously planned share repurchase for the LifeLock acquisition which we determined to be a better use of shareholder capital. Many of our existing long-term focused shareholders are well aware of these moving parts, but for those that are new to Symantec, we believe it is helpful to frame the changes over this timeframe and since this initial fiscal year 2018 non-GAAP EPS range was issued, to where we are today. Moving to our first quarter outlook, given the integration of our acquisitions, business process changes, and modification to sales coverage we put in place at the beginning of April, as well as the shift to more subscription business, we believe it is prudent to set measured first quarter guidance. We expect non-GAAP revenue for the first quarter to be up 37% to 40%, which at guided rates translates to $1.1 billion to $1.2 billion. We expect Enterprise revenues to increase 36% to 40% and Consumer revenue to increase 38% to 40%. We expect operating margins to be 27% to 29%, and expand sequentially each quarter from there. We expect non-GAAP EPS of $0.28 to $0.32 and an underlying share count of 667 million shares. We will share additional details on the outlook of each of our businesses at our Financial Analyst Day in June. So in summary, business activity and momentum with customers was strong as we exited fiscal year 2017. Financially, we saw stronger than expected subscription in our product mix, which impacted end period revenue, but was more than offset by our cost management, driving operating margins and earnings to the high end of our prior guidance. At the same time, our integration, transformation and business process work is going well and is setting us on firm footing to realize the value propositions we outlined to you related to the acquisitions in both our Enterprise and Consumer business segments. Our financial guidance for fiscal year 2018 reflects our work and the fundamental change taking place at Symantec. From a revenue perspective, we expect to see the benefits accrue later in the year, as all of the changes take root and yield results. With 8 to 9 points of operating margin growth, and 52% to 61% non-GAAP EPS growth in fiscal year 2018, we believe the company will be set on a strong trajectory of long term sustainable growth with leading profitability for the future.
