Our revenues of $26 billion in the second quarter demonstrate the ongoing momentum in our businesses with broad-based strength globally. Revenues were up 21% year-on-year, and up 23% in constant currency. Advertising revenues benefitted from the strong performance insights, which was led in particular by tremendous results in mobile search with a strong contribution from YouTube. Healthy growth and network revenues was driven by our programmatic business. We also had substantial growth in other revenues from Cloud, Play and hardware. Our outline for today's call is first I'll review the quarter on a consolidated basis for Alphabet focusing on year-over-year changes. I will review our results on a GAAP basis, which include the impact of stock-based compensation. The European commission fine of $2.7 billion is reflected in our GAAP results with the fine displayed as a separate line item for clarity. In order to assist with comparing this quarter's results to prior periods, we are also providing operating income, net income and EPS results that exclude the impact of the fine. The fine is not reflected in our segment results. Second, I will review results for Google and then Other Bets. Finally, I will conclude with our outlook. Sundar will then discuss our business and product highlights for the quarter after which we will take questions. I will start with the summary of Alphabet's consolidated financial performance for the quarter. Total revenues were $26 billion up 21% year-over-year. We realized a negative currency impact on our revenues year-over-year of $364 million or $361 million after the benefits of our hedging program. Holding currency constant to the prior period, our total revenues grew 23% year-over-year. Turning to Alphabet revenues by geography. You can see that our performance was strong in all regions. U.S. revenues were up 23% year-over-year to $12.3 billion. EMEA revenues were $8.5 billion up 14% year-over-year reflecting weakness in the British pound and the euro. Revenues were up 21% in fixed FX terms. APAC revenues were $3.7 billion up 28% versus last year and up 27% in fixed FX terms. Other America's revenues which include results from Canada and Latin America were $1.4 billion up 31% versus last year in both reported and fixed FX terms. On a consolidated basis, total cost of revenues including TAC, which I'll discuss in the Google segment results were $10.4 billion up 28% year-on-year. Other cost of revenues on a consolidated basis was $5.3 billion up 27% year-over-year primarily driven by Google related expenses. Specifically, costs associated with operating our datacenters including depreciation, content acquisition costs primarily for YouTube and hardware related costs. Operating expenses including the impact of the EC fine are $11.5 billion. Excluding the impact of the EC fine operating expenses were $8.8 billion up 18% year-over-year. Year-on-year expense growth reflects the change in the timing of our annual equity refresh cycle from the third quarter to the first quarter of each year. As discussed previously, this affects the quarterly pace of stock-based compensation in 2017, but not the overall size of the expense for the year. In order to transition to the new timing, we made a one-time half year grant in Q1 of this year, which is reflected in elevated year-on-year expense growth in Q2. As a result, stock-based compensation totaled $2 billion up 33% year-over-year. Headcount at the end of thank you quarter was 75,606 up 1,614 people from last quarter. Consistent with prior quarters, the vast majority of new hires were engineers and product managers. In terms of product areas the most sizable headcount additions were once again made in Cloud for both technical and sales roles consistent with the priority we place on this business. Operating income was $4.1 billion, excluding the impact of the EC fine, operating income was $6.9 billion up 15% versus last year and the operating margin was 26%. Other income and expense was $245 million. We provide more detail on the line items within OI&E in our earnings press release. Our effective tax rate was 19.5% for the second quarter, net income was $3.5 billion and earnings per diluted share were $5.1. Excluding the impact of the EC fine, net income was $6.3 billion and earnings per diluted share were $8.90. Turning now to CapEx and operating cash flow. Cash, CapEx for the quarter was $2.8 billion. Operating cash flow was $7.4 billion with free cash flow of $4.6 billion. We ended the quarter with cash and marketable securities of $94.7 billion of which approximately $57.9 billion or 61% is held overseas. Let me now turn to our segment financial results. Starting with the Google segment. Revenues were $25.8 billion up 21% year-over-year. In terms of the revenue detail, Google sites revenues were $18.4 billion in the quarter up 20% year-over-year. The biggest contributors to growth again this quarter were mobile search and YouTube. Network revenues were $4.2 billion up 13% year-on-year, reflecting the ongoing strength of programmatic and AdMob. Other revenues for Google were $3.1 billion up 42% year-over-year, we have been talking about our bigger investment areas within Google and you can see the momentum here reflecting contributions from our newer revenue streams again this quarter on top of the ongoing strength in Play. Specifically Cloud continues to benefit from the ongoing investments in our go-to-market and product efforts. Hardware continues to grow at a healthy pace year-on-year with the extension of our product line geographically, particularly Google Home and Wi-Fi, the dollar impacted growth was more muted than in prior quarters reflecting seasonality. Finally, we continue to provide monetization metrics to give you a sense of the price and volume dynamics of our advertising businesses. You can find the details in our earnings press release. Total traffic acquisition costs were $5.1 billion, or 22% of total advertising revenues, and up 28% year-over-year. The increase in both Sites TAC as a percentage of Sites revenues, as well as Network TAC as a percentage of Network revenues, continues reflects the fact that our strongest growth areas, namely mobile search and programmatic, carry higher TAC. Total TAC as a percentage of total advertising revenues was up year-over-year as a result of an increase in the Sites TAC rate, driven by the shift to mobile, which was again partially offset by a favorable revenue mix shift from Network to Sites, which carries lower TAC. Google's stock-based compensation totaled $1.9 billion for the quarter, up 40% year-over-year. Operating income, including the impact of SBC, was $7.8 billion, up 12% versus last year, and the operating margin was 30%. Accrued CapEx for the quarter was $2.8 billion, reflecting investments in production equipment, facilities, and data center construction. A couple of Google reminders for the third quarter. Headcount additions tend to be seasonally high in Q3, because that is when we bring on new graduates. In addition, please keep in mind that our marketing costs are typically weighted more heavily toward the back-half of the year due to the holiday season, particularly as we promote our made-by Google line of hardware products. Let me now turn and talk about Other Bets. For the second quarter, Other Bets revenues were $248 million primarily generated by Nest, Fiber and Verily. Operating loss, including the impact of SBC, was $772 million for the second quarter. Other Bets accrued CapEx was $152 million, primarily reflecting a reduced investment in Fiber due to the pause in expansion we announced in 3Q 2016. We're pleased with our progress across Other Bets, a couple of updates. Nest continues to drive ongoing product expansion, such as our recent introduction of the indoor security camera, Nest Cam IQ as well as geographic expansion both of which support its position as the leading brand in the connected home. In life sciences, in addition to our progress at Verily, Calico has focused its efforts on the basic mechanisms of ageing and three ageing related diseases representing the leading causes of death. Calico has established more than 20 active collaborations with other life sciences companies and academic institutions. With Loon we recently demonstrated the technology in Peru by successful delivering basic internet connectivity to tens and thousands of people affected by the tragic floods there. We worked in partnership with the Peruvian government and Telefonica. And our progress with Waymo continues nicely, as it is reflected in the writer program in Phoenix and our recently announced partnerships with Lift and Avis. Let me wrap up, almost two years after the creation of Alphabet, we see the benefits of our focus within Google and Other Bets and are pleased with the opportunities we have for sustained revenue and earnings growth. We are obviously very happy with the ongoing strength in ads revenue, particularly in Search. Our compelling secular trends continue to drive user adoption and engagement with mobile devices. Our engineering and machine learning acumen enables us to build better experiences for users and advertisers. We continue to see increasing contributions from our growing non-ads revenue businesses, Play continues to be a strong contributor, in addition we have been making big Bets within Google focused on Cloud, hardware and subscription businesses in YouTube in order to better serve customers, while also building additional and differentiated revenue streams. These businesses are consistent with and complementary to our core capabilities and leverage our infrastructure, distribution and engineering. We believe we have a compelling runway here. Longer-term we see great opportunity in the businesses we are building in Other Bets. These businesses reflect the incredible engineering talent across Alphabet most notably in machine learning. Our revenue growth and Alphabet structure give us both the opportunity and confidence to invest in our businesses for the long-term. We are doing that, while being very deliberate about the focus, scale and pace of investment and remain committed to being consciences in our use of all resources. We're increasing investment in areas where we see the most potential scaling back and others and sharpening our organizational effectiveness to make the most of the resources available. Thank you. And let me now turn the call over to Sundar.
