We continue to make progress on integrating the Ameron Water Transmission Group into Northwest Pipe. This acquisition has created a strong platform that's expected to have major impact on the ongoing earning potential of the company. As of December 31st, 2018, our backlog, including confirmed orders, was $252 million, an all time record compared to $201 million in the third quarter, and $88 million in the fourth quarter of 2017. The significant increase in backlog at year-end was a result of a strong fourth quarter bidding opportunities that we've discussed in our previous calls. The current demand levels, along with a stable competitive landscape should lead to a stronger first quarter than we've seen recently bucking the trend for relatively slow first quarters for the last three years. We expect first quarter to be similar to the fourth quarter of 2018 with respect to revenue and gross profit. Furthermore, we expect continuing improvement in revenues and margins as we progressed through the rest of 2019. The following is a look at current and upcoming water transmission projects. In the Texas market, the SWIFT program has funded over $8 billion in projects over the last six years. SWIFT is expected to continue to fund major projects like the Houston Project in Bois d'Arc Reservoir well into the future. The Houston Surface Water Project is a major multi-year, multi-agency program with a series of segments representing 90,000 tons of pipe. Northwest Pipe has been the successful bidder on multiple Houston segments, representing over 150,00 tons of pipe. The production of the individual segments are in various stages from pre-manufacturing to ship complete. There are additional segments of Houston project that will bid throughout 2019 and 2020 that represent about 35,000 tons of pipe. The Bois d'Arc Reservoir project by the North Texas Municipal Water District has begun construction and represents approximately 60,000 tons of pipe. Northwest Pipe was the successful bidder on a portion of the raw water line for Bois d'Arc in the fourth quarter of 2018. The segments that we were awarded represent approximately 25,000 tons of pipe scheduled to be produced in 2019. The finished water line for this project is forecast to bid in the first half of 2019 and represent an additional 22,000 tons of pipe. In the Western market, the $2.6 billion California reline program began in 2017 and will be active over the next 20 years. In 2018, Northwest Pipe was successful bidder on to reliner segments. First, the 6,000 ton MWD reline project on which production began in the fourth quarter, and will run through the first quarter of 2019. And the 3,500 ton San Diego County Authority reline project with production that will run through the first quarter of 2019. Two to three additional reline segments will bid each year, representing 8000 to 10,000 tons of pipe annually. The city of San Diego's $1.7 billion pure water program is a 6000 ton project that is scheduled to begin bidding in the first half of 2019. The Santa Clara Valley Water District's $1 billion pure water program represents 8500 tons of pipe projected to start bidding in early 2020. In North Dakota, progress has slowed on 140 mile, 87,000 ton Red River Valley Water Supply Project, as it is competing for funding with an urgent flood diversion project, which appears to be taking priority. We are hopeful that beginning on this project will start sometime within the next year. With a very strong backlog coming out of 2018 and a solid bidding year projected for 2019, along with a stable bidding environment, we expect a positive trend in revenue and margins throughout 2019. And because a substantial portion of the project is currently bidding on multi-year programs, we expect to see continued strength in the backlog, which should translate into positive business conditions beyond 2019. The acquisition of the Ameron Water Transmission Group further strengthens our position in the business. In closing, as we move forward, we will remain focused on, one, the successful integration of the Ameron Water Transmission Group, two, improving the performance of the business by focusing on margin over volume, and three, driving cost reductions and efficiencies at all levels of the company. At this time, we would be happy to answer any of your questions.
