With the progress we made in 2017 our business is strong heading into 2018. Over the last few quarters I have been messaging that our 2018 results will be choppy due to the refranchising of several markets in 2017 and the $100 million of depreciation benefit in china and Hong Kong in 2017, associated with the refranchising of those markets. Looking forward we expect 2018 results to be even a little more choppy, with U.S. tax reform and a new level recognition accounting standard that went into effect January 1, this year. On revenue recognition while the new accounting standard will have no impact on our cash flows the change will affect the way we recognize revenue for initial franchise fees that we received, for new restaurant openings and new franchise terms. Previously we recognized initial franchise fees when we received them, upon opening new restaurants or granting a new franchise term. Beginning in 2018 we will recognize that income over the life of the franchise term. For this year we expected this change to have a negative impact of about $50 million on our consolidated franchise revenues and franchise margins. I talked to you about the impact of U.S. tax reform on our 2017 results and I'll spend a couple of minutes walking through how we expect the full impact of business going forward. All of this is based on available information and our current estimates which we know could change as further clarifications provided and our analogies are finalized. From an earnings standpoint we expect our effective tax rate for 2018 to be 25% to 27%, down from our historical range of 31% to 33%. Our global blended rate will be higher than the new U.S. rate due to taxes that we pay outside of the U.S. which currently average close to 30%. From a cash flow standpoint, we expect an incremental benefit of 400 million to 500 million annually prior to any reinvestment. A few points to put this in the perspective. First, we historically have not had a large amount of cash held overseas. So, the new law will not result in us suddenly bringing back a lot of cash. Second, this incremental cash flow represents less than 10% of our historical annual operating cash flow of roughly $6 billion. Finally, we have not been capital constrained in the past, so we expect our capital allocation priorities to remain consistent with what they have been. First, to reinvest in existing restaurants and invest in opportunities to grow the business; second, to pay dividends, and third, to repurchase our stock. Having said that we now expect to return about 24 billion to shareholders for the three-year period ending 2019 which is at the high end of our previously stated target. From a business operation standpoint, we expect our U.S. franchisees in general to also benefit from tax reform. Given the ongoing strength of our franchisees existing cash flow this benefit should enhanced our ability to invest in and execute on the velocity growth plan. Next, I want to take a moment to review the progress we've made on our financial targets around refranchising and G&A. During 2017 we completed transactions in the Nordics, Taiwan, China and Hong-Kong which, enabled us to reach our targets to refranchise 4,000 restaurants. We begin 2018 ready to operate under the streamlined and more heavily franchise business model that we set out to create under our turnaround plan. While we do expect to continue to refranchise some of our company owned restaurants in our major markets like the U.S. international league markets we anticipate the gains on sales of restaurants in 2018 will be down roughly 30 million to 40 million from 2017 as our refranchising activity begin to slow down. Regarding G&A we developed the targets savings of $500 million from our base of $2.3 billion at the beginning of 2015. Through 2017 we have realized about $300 million of net savings. In order to achieve those net savings, we save significantly more than $300 million on a gross basis related to maintenance spending. And then reinvested some of those savings primarily in technology and digital. So, at the same time we saved cost overall, we've also shifted more of our remaining spend from maintenance spending to investing in activities that drive growth. For 2018, we expect G&A to decline by 1% in constant currencies. This reflects savings from our refranchising transactions and a reset of our incentive compensation offset by one-time cost associated with our bi-annual worldwide operator convention to final year of our Olympics sponsorship and our upcoming headquarters office move, as well as continued spending in technology. We expect to fully realize our targeted $500 million of net savings in 2019. As we have become more efficient with the G&A required to run the business we will continue to invest in activities that we believe can accelerate growth. At the same time, we will continue to exercise strong financial discipline in the use of our valuable resources. Moving on to capital, we expect to end 2017 with capital expenditures of nearly $1.9 billion. This was slightly higher than we anticipated at the beginning of the year because of currency exchange rates and because we were able to complete more EOTF projects in the US than planned, ending the year with 3000 EOTF restaurants as Steve mentioned. In 2018 we expect to spend about $2.4 billion of capital, approximately 1.5 billion or two-thirds of our capital will be dedicated to our US business, primarily focused on further acceleration of experience of the future. Of the remaining capital budget about half is earmarked for new restaurant openings and half is allocated to reinvestment as we continue to expand the experience of the future in markets outside the US. Our capital will contribute to about 250 new store openings while capital from developmental licensees and affiliates will contribute to another 750 openings for a total of a 1000 planned new restaurants. Finally, for 2018 we anticipate some currency tailwind primarily in the first half of the year. At current exchange rates we expect a positive impact of $0.07 to $0.09 in the first quarter and $0.23 to $0.25 for the full year. As you know over the last month exchange rates have fluctuated more significantly than we've typically seen and we don't know what will happen to rest of the year. So please take this as directional guidance only. We've made significant progress in our business. The path that we're on with the velocity growth plan along with the investments we're making in our future position the company for sustainable long-term growth. We remain confident in our ability to achieve our long term financial targets beginning in 2019 and now I'll turn it back to Steve.
