For our call today, I will discuss key financial highlights from the quarter and then turn the presentation over to Dave Goodin, President and CEO of MDU Resources, for his formal remarks. After Dave’s remarks, we’ll open the line for questions. In addition to Dave and myself, members of our management team who will be available to answer questions today are Dave Barney, President and CEO of Knife River Corporation; Jeff Thiede, President and CEO of MDU Construction Services Group; Nicole Kivisto, President and CEO of Cascade Natural Gas, Great Plains Natural Gas, Intermountain Gas and Montana-Dakota Utilities; Trevor Hastings, President and CEO of WBI Energy; and Stephanie Barth, Vice President, Chief Accounting Officer and Controller for MDU Resources. Yesterday, we announced our second quarter earnings from continuing operations of 44.1 million or $0.22 per share compared to 43.8 million or $0.22 per share in 2017. On a consolidated basis, earnings were 43.8 million or $0.22 per share compared to 40.6 million or $0.21 per share in 2017. Our construction services business reported earnings of 14.1 million compared to 12.4 million in 2017, with second quarter revenues of 323.6 million compared to second quarter 2017 revenues of 336.3 million. This increase in earnings was primarily the result of lower income tax expense due to the enactment of the Tax Cuts and Jobs Act. Higher gross margins were the result of increased outside specialty contracting workloads, driven by customer demand for outside equipment sales and rentals, partially offset by lower inside specialty contracting workloads. Offsetting the increase in gross margins was higher selling, general and administrative expense, primarily from payroll related costs, which resulted in a decreased operating income. Our construction materials business reported second quarter earnings of 24.3 million compared to 21.2 million for the same period in 2017 with revenues of 509.6 million, up from 501.6 in the prior quarter. The increase in earnings was the result of lower income tax expense due to the enactment of the Tax Cuts and Jobs Act. Lower overall material product margins, which negatively impacted our operating income, were partially offset by higher construction margins. For the quarter, our combined utility business reported earnings of 2.3 million compared to 5 million in the second quarter of 2017. The electric utility segment earned 9.1 million for the quarter compared to 7.8 million in 2017. This increase in earnings reflects higher electric adjusted gross margins, resulting from 5% higher retail sales volumes to all major customer classes. Partially offsetting the increase was higher operation and maintenance expense, largely from increased contract services and payroll related costs as well as higher depreciation, depletion and amortization expense. Our natural gas utility segment reported a seasonal loss of 6.8 million for the quarter compared to a loss of 2.8 million for the same period in 2017. The main driver behind this decrease in earnings was increased operation and maintenance expense, which reflects certain one-time adjustments related to the recent Washington Utilities and Transportation Commission’s general rate case decision, which included the effects of federal tax reform as well as higher payroll related costs. Also contributing to the decrease was higher depreciation, depletion and amortization expense from increased plant additions. At our pipeline and midstream business, earnings were 5.7 million in the second quarter compared to 5.3 million in 2017. This increase in earnings reflects lower income taxes due to the enactment of the Tax Cuts and Jobs Act and higher non-regulated project revenues. Increased transportation volumes from new organic growth projects were more than offset by decreased storage related revenues and higher depreciation, depletion and amortization expense. Also offsetting the increase in earnings was higher operational maintenance expense, largely from increased costs on our non-regulated projects. And now, I'd like to turn the call over to Dave for his former remarks. Dave?
