Thanks Mark. As you're aware, Steve took the role of Executive Vice Chairman two years ago and has been an integral part of Canadian Natural for 28 years, and has now decided to retire this May. Steve has done a fantastic job over the many years as the company transitioned to the more robust long life, low decline company we are today. As well through the many years, Steve has mentored all of the MCM members, ensuring a smooth transition, which is a strength of the company and the people we develop. We look forward to continuing to work with Steve as he will continue to contribute to our success as an active Board member. Canadian Natural's advantage is our ability to effectively allocate cash flow to our four pillars. We will continue balanced, optimize our capital allocation, deliver free cash flow and strengthen our balance sheet. We have a well balanced, diverse, large asset base a significant portion of our asset base is long life low decline assets, which require less capital to maintain volumes. We have balance in our commodities with approximately 49% of our BOE, light crude oil and SEO, 28% heavy and 23% natural gas, which lessens our exposure to the volatility in any one commodity as we move through 2020. Canadian Natural will continue to allocate cash flow to our four pillars in a disciplined manner to maximize value for our shareholders, which is all driven by effective capital allocation, effective efficient operations and by our team who delivered top-tier results. We have robust sustainable free cash flow and in 2019 returns to shareholders were significant, $1.7 billion dividend, $9.9 billion in share purchases for a total of $2.6 billion. Today, our dividend was increased by 13% and we have 20 consecutive years of dividend increases, which has a CAGR of 20%. Share purchases in 2020 were approximately $6.6 million shares or $260 million year-to-date as we continue as per free cash flow allocation policy. In 2020, as a result of the volatility of oil pricing, Canadian Natural has reduced its capital budget by approximately $100 million in our oil sand business, deferring work into 2020 that we can plan and execute more effectively and efficiently, which has no impact on 2020 production volume. In 2020, we will continue to drive our environmental performance to meet and exceed our targets we set in December 2019. In summary, we will continue to focus on safe, reliable operations and enhancing our top-tier operations. We are in a very strong position and being nimble, which enhances our capacity to create value for our shareholders. Our procurement optimization strategy is a reflection of our ability to be nimble and operate with excellence. Canadian Natural is delivering top-tier free cash flow generation and is unique, sustainable and robust and clearly demonstrates our ability to both economically grow the business and deliver returns to shareholders by balancing our four pillars. With that, we will open up the call for questions.
