Thanks, Rafael, and good morning everyone. We had a solid operational start to the year despite the challenges in our North America, OEM markets and ongoing disruption from the pandemic. We demonstrated our ability to deliver on synergies, generate cash flow, invest for the future, and position Wabtec for profitable growth. Turning to slide four, our view of the first quarter in more detail. Sales for the first quarter were $1.8 billion, which reflects a 5% decrease versus the prior year, driven by lower North America OE freight markets as a result of the disruption caused by the pandemic. For the quarter, operating income was $192 million, and adjusted operating income was $277 million, which was down 9% year-over-year. Adjusted operating income, excluded pre-tax expenses of $85 million, of which $70 million was for non-cash amortization and $15 million of restructuring and transaction costs related to the acquisition of Nordco, along with restructuring due to the 2021 locomotive volumes and restructuring in our UK operations. Adjusted operating margin was 60 basis points lower than the first quarter last year, but up 110 basis points from the fourth quarter. Versus last year, adjusted operating margin was impacted by under-absorption costs at our manufacturing facilities, stemming from fewer locomotive deliveries, as well as sales mix impacted from lower digital electronics and a higher level of transit sale. At March 31st, our multiyear backlog was $21.7 billion, up quarter-over-quarter, a rolling 12-month backlog, which is a subset of the multi-year, was $5.7 billion and continues to provide good visibility into the year. Looking at some of the detailed line items for the first quarter, adjusted SG&A declined to 2% year-over-year to $224 million. This was the result of cost actions during the downturn, and excludes $11 million of restructuring and transaction expenses. SG&A expense benefited from headcount reductions and the realization of synergies.
