Thank you, Jim. With first quarter sales volume typically at seasonal low points, we're usually focused on a few other key measures to gauge whether the year is off to a good start. Sales volume was very close to forecast and when adjusting for the increase in legal expenses, EPS and EBITDA would have improved significantly over prior year on 3.2% better sales volume. Working capital was solid with only a modest increase in inventory as we prepare for increased volume in Q2. We generated cash in the quarter and more importantly, new orders and backlog were very strong, putting us in a position to boost sales in Q2 substantially over the first quarter. In addition, our debt position improved further as we took advantage of our foreign cash to pay down debt. We were very pleased to see solid order growth and double-digit backlog growth compared to prior year, particularly in light of the strong start we had last year. I'll spend more time on orders and backlog, but I'll begin with comments regarding the first quarter operating performance, The continued improvement in the tubular and energy services segment drove the consolidated first quarter gross profit increase, increased activity in the energy markets we serve particularly the midstream segment helped deliver a 26% sales increase in our tubular and energy segment over prior year, which drove significant operating leverage in the segment. While we're getting most of the tubular gross profit increase from projects that support midstream pipeline applications, the single greatest increase in sales is from the test and inspection services division that primarily serves upstream applications. The rail business segment had a very good quarter as well with sales up 10%, rail technologies drove most of the growth with a substantial impact from project and service activity in Europe, excellent expense control across the business group led to significant segment profit improvement over prior year. The construction segment unfavorably impacted results as volume declined from a very solid first quarter in 2017 since then grid decking projects have declined and piling sales are lower as a result of declining sales and commodity piling since the first quarter of 2017. We were pleased to see much better piling order activity in Q1 as bookings far exceeded sales. Across the entire company, our discipline around cost control continued in Q1. Excluding the $1.2 million increase in legal expenses, we kept SG&A costs flat with Q1 last year. We were anticipating an increase in legal expenses related to the Union Pacific concrete time matter, as we prepare for an October trial date. We are subject to court established deadlines regarding the completion of discovery, preparation and filing, our pretrial motions and other requirements, which will result in additional work in the second quarter. This activity will keep legal expenses above 2017 levels. A significant amount of work was done in Q1 related to fact and expert discovery, which is necessary to support our position. EBITDA performance in the first quarter was flat; however, excluding the increase in legal expenses, our operations performed much better than prior year. We did incur minor reorganization cost in the quarter and expect a few more small operational projects throughout 2018, intended to reduce cost. The team we have assembled overseeing operations has done a great job focusing on cost control and managing to deal with the growth throughout the last year without adding expenses back too fast. This take a great deal of focus and leadership on the part of our operating leaders, all of whom took on more responsibility late last year, starting with when we put the construction organization under John Castle, who continues to oversee the rail business as well. Greg Lippard is looking after key parts of the rail segment, including oversight of our key rail services expansion and Bill Tracy is looking after the tubular and energy services businesses with a great deal of emphasis on the upstream test and inspection division. These leaders and their teams are driving the key operational improvement programs and implementation of the important processes that are part of our operating business system. Let me turn to cash and the balance sheet discussion. Our ability to generate cash in Q1 is an excellent way to start the year. There's always pressure on cash in the first quarter with the low sales volume and the need to prepare for second quarter shipments. Generating $2.6 million in cash was significant as we strive to make progress every quarter in debt reduction and as previously mentioned, we intended to take advantage of our foreign cash position and apply it to all $24.7 million of cash repatriated to debt reduction. This and other working capital programs have reshaped our balance sheet significantly over the last five quarters. Our leverage ratio has improved further and as Jim said, our interest rates will be lower beginning in May. Capital spending was modest at $723,000 in Q1. Following $814,000 in the fourth quarter of last year, we've completed a period where we had intended to get CapEx to the bare minimum and we expect to increase this spending in future quarters as more opportunities are surfacing to fund growth and efficiency improvement. Turning now to new orders and backlog growth, the highlights, start with the fact that all three reporting segments realized increases in new orders in the first quarter. The rail segment order growth was the greatest at 10.2% lifting our backlog to 14.5% over prior year, new rail orders and projects serving the transit rail market provided the momentum. Our rail distribution business continues to recover from the decline two years ago, including increasing pricing. Across the world, we continue to see transit operators investing in infrastructure with expansion and modernization of existing operations. The freight rail operators in North America have been increasing spending on our products throughout 2017 and the activity in Q1 of 2018 showed continued growth in orders. Freight rail traffic in North America continues to look like it's improving, although Q1 typically has lower traffic due to seasonal demand in the industry. Friction management is becoming increasingly important to freight railroads as some see the demonstrated savings and wear and tear and our initiatives around growth and service contracts for friction management are moving forward as our team now covers U.S. locations from the East Coast to the West Coast. Tubular and energy services was right behind the rail segment in terms of order growth, with 9.6% in Q1 helping drive the backlog increase of 21% year-over-year. The backlog growth looks more substantial due to the increasing pace throughout 2017. Project in the midstream energy market have increased as new projects are getting funded, helping drive significant backlog increase especially from new orders and protective coating services. The increased activity in pipeline projects is most prominent in the regions where production increases are taking place in oil and gas development and where capacity shortfalls or the need to reach new locations exists. We're experiencing the same project activity strength in our measurement solutions business as the same midstream customers are in need of measurement solutions as pipelines are constructed. We're looking forward to this activity turning into an increase in new orders. It's not clear at this time whether the increase in spending is being impacted by users attempting to get ahead of anticipated cost increases in steel pipe that may be forthcoming due to tariff activity. A number of other favorable energy market indicators include the price of oil, finding support in the $60 range as a result of demand strength, low cost developers in the U.S. are better positioned to take production to all-time record levels due to substantial productivity gains and we continue to see rising rig counts in the United States. Tubulars needed to support the growth and number of wells and well depth is expected to drive demand for our services. Pricing is still a struggle in the upstream energy market and we are working diligently to restore margins to prior levels. And finally changes with Pemex are opening doors to other oil companies in Mexico. We are benefiting from new additive and injection systems being supplied to integrated oil companies that are getting more established in Mexico's gasoline distribution network. Construction orders were up 3% in Q1 and we were very pleased to see an 8% increase in backlog over prior year. The backlog growth in piling more than offset the decline in the bridge decking backlog and while we haven't had a large project in the bridge decking business, orders were very solid in the quarter on small and midsized projects. We are making some investments in piling inventory to take advantage of opportunistic projects that can ship from stock. Some projects are moving forward quickly as end-users potentially fear rising cost of steel products due to tariffs. Another strong indicator for the construction segment is backlog improving by $14.4 million or 20% since the beginning of the year, standing at $86 million at the end of March, we have more backlog than we did at any point last year in the construction segment. So in summary, it was a solid quarter for bookings across all three segments. We will start the second quarter with a backlog of $220 million. We anticipate solid revenue growth next quarter both sequentially and year-over-year and while we have a significant amount of piling and rail distribution growth occurring this year, our consolidated gross margins are expected to increase sequentially over Q1 by as much as 200 basis points. Now before I conclude my comments on operations, I thought I would make a quick comment on Section 232 and steel prices. Since the Section 232 Act creating tariffs and quotas on steel was enacted, we've tracked several price increases related to various steel products. We still see a great deal of uncertainty regarding forecasts of bow each market or product may be affected, particularly in light of negotiations and applications for exemption that are still taking place. Markets we serve where steel is a major component have wide raging supply chain characteristics as it relates to foreign-made product. This is making it difficult to quantify changes and forecast the impact of each of our markets at this time. The significant part of our steel spend is within the new rail distribution and piling distribution businesses. In each of these businesses, we buy and resell product often for specific projects where the input costs are known before we price the project. This allows us to evaluate our gross margin on the project and determine the end market price accordingly. During Q1, we did experience increases in steel input costs in both businesses. We are also selling product from inventory and from time to time, this can lead to favorable and unfavorable variances as prices fluctuate. In the past, we've demonstrated that we can manage through environments where prices are changing, increasing the price environments and distribution businesses, are typically viewed as favorable as they lift sales revenue and provide an opportunity to make more profit at the same margin. Raw material prices for bridge decking projects is on the rise. We attempt to pass these costs on, but there can't be a lag before the selling price catches up with rising input costs. We attempt to protect ourselves from such risks through the use of the index escalators or bid expiration dates where possible. We can also be impacted by quotas on foreign sources for oil country tubular goods and line pipe. I believe we are benefiting today from being aligned with an American-made line pipe supplier for midstream pipe applications. Order activity has been very strong since the first of the year and it's all with our American mill partner. We do provide services on foreign-made pipe for drilling applications. Korean made pipe is a significant component of the foreign sourced pipe. Reduction in supply of this pipe could shift supply to American mills in a short period of time. We also serve the American suppliers however. The impact in our revenue will depend on who customers choose as their pipe supplier. I'm going to end my comments there and will turn it back to the operator for questions.
