Thanks Patrick. Turning to Slide 7 in the presentation. The company's total revenues for the second quarter were $362.4 million, a 1% increase from $358.1 million a year ago. The overall gross margin increased 2 percentage points from last year to 30.7% driven mainly by improved margins in oilfield services and performance chemicals. EBITDA for the quarter was $43.8 million, up slightly on last year. Our GAAP earnings per share were $0.90, including special items, the net effect of which decreased our second quarter earnings by $0.22 per share. A year ago, we reported GAAP earnings per share of $0.89, which included an adverse impact from special items of $0.11. Excluding special items in both years, our adjusted EPS for the quarter was $1.12, a 12% increase from $1 a year ago, demonstrating the value of our strategic businesses and the strength of our overall portfolio. It's worth noting that the results were impacted by around $0.06 due to higher share-based compensation accruals and by approximately $0.20 due to a lower octane additives contribution. Even with these headwinds, the business has posted some impressive results. Moving on to Slide 8. Our oilfield services business has delivered excellent results in the quarter. Revenues of $122.5 million were up 29% on the same period last year driven by good customer activity in both stimulation and production. Customers are continuing to find our combined technology and service offering very attractive, and our market share continues to grow. Gross margins improved 3.8 percentage points as the sales mix improved in the quarter. As we previously indicated, the growth and margin improvements, combined with good cost control, has generated a substantial improvement in operating income, which is up to $10.1 million for the quarter, compared to just $4.1 million in the same period last year. Turning to Slide 9. Revenues in performance chemicals for the second quarter were $104.7 million, down 12% from $118.9 million a year ago, driven by a 5% reduction in volumes, a negative currency impact of 4% and an adverse price/mix of 3%, as reduction in raw material prices translated into lower selling prices. Despite the reduced revenue, we have further improved margins as part of our long-term strategy with gross margins up 2.9 percentage points. Operating income was up 13% to $11 million from $9.7 million in the same quarter last year. Moving on to Slide 10. Fuel specialties produced a very solid set of results in the quarter, right on our expectations. Revenues for the second quarter were $133.3 million, down by 1% from last year, as a positive price/mix of 5% was offset by an adverse currency impact of 4%, combined with a 2% reduction in volumes. Gross margins of 33.5% were similar to the comparative period and within our expected range. Operating income was up around 1% to $24.1 million. Moving on to Slide 11. In octane additives, revenues for the quarter were $1.9 million, compared to $10 million a year ago; operating income of $0.1 million, compared to $5.2 million in last year's second quarter. We are currently working to fulfill an order of approximately $6.5 million which we booked in Q3. Beyond this, we have limited visibility as our expectation is for one smaller final order in Q4. We will continue to update you on these quarterly calls. Turning to Slide 12. Corporate costs for the quarter were $13.6 million, compared to the $14.4 million recorded a year ago. The effective tax rate for the quarter was 26.9%, similar to the 26.1% of last year, driven by the geographical location of taxable profits. Moving on to Slide 13. Net cash provided by operating activities in the quarter was $50 million, compared to $2.3 million a year ago. In the quarter, the company also distributed $12.2 million to shareholders for the semiannual dividend. As of June 30, 2019, Innospec had $106.1 million in cash and cash equivalents and total debt of $160.9 million, moving our net debt position to approximately 0.3 times EBITDA. I'll now turn it back over to Patrick for some final comments.
