Thanks, Corey. As you all read, Corey Bieber, our CFO for the last six years had decided to take a somewhat less demanding role in the company as Executive Advisor effective March 31, 2019. As a result of this change, effect of March 31, Mark Stainthorpe will be promoted to Chief Financial Officer. Many of you know Mark, who is a very talented individual with strong financial and leadership skills, and has been mentored by both Corey and Steve over the last 12 years. I'm very confident that he will do a great job in leading a strong financial team. Of course, Corey will still be around to provide Mark and Ron with all the help they will need. Similarly, Ron Kim would be promoted to Principal Accounting Officer effective March 31, 2019, working together with Mark. Ron brings great deal of technical, accounting and taxation expertise. We believe that this team will add significant value to shareholders and complements the experience that Corey has brought to the table. These changes would be subject to board approval in March of next year. In summary, Canadian Natural has many advantages, our balance sheet is strong, we continue to strengthen it, we have a well-balanced, diverse and large asset base. A significant portion of our asset base is long life low decline assets, which requires less capital to maintain volumes. Our balance for commodities with approximately 50% of BOEs, light crude 25% heavy and 25% natural gas, which lessens our exposure and volatility in any one commodity. We're delivering substantial free cash flow, which we're effectively allocating to our four pillars. Canadian Natural will continue to allocate cash flow to our four pillars to maximize value our balance sheet continues to strengthen, we continue with discipline resource development, return to shareholders has been strong at 22% dividend increase earlier this year, and year-to-date we have bought back 27 million shares. Finally, while we have no gaps in our portfolio, potential acquisitions should we choose so. This is all driven by effective capital allocation, effective and efficient operations by our teams deliver top tier results. With that, we will open the call to questions.
