Thanks, Tom. Good afternoon everyone. I will review our financial results at the halfway point of this year. As Tom just reviewed, we had a solid second quarter with net income of $3.6 million or $0.24 per share, and for the six month period we reported net income of $19.2 million or $1.30 per share, up $0.19 or 17% over the same six month period in 2017. Now let's take a look of how we got there. Turning to Slide 10; natural gas sales margins were $22.9 million and $62.8 million in the three and six months ended June 30, 2018 respectively, which reflect increases of $2.4 million and $4.3 million respectively compared to the same periods in 2017. Gas sales margin in the for the six months of 2018 was positively affected by higher natural gas distribution rates of $4.8 million, including as a result of the final base rate award in the company's New Hampshire gas utility, a concurrent non-recurring adjustments to increase revenue and O&M expenses by $1.2 million in the second quarter of 2018 to reconcile permanent rates and deferred cost to the temporary rates which were effective July 1, 2017. Gas margin in the for the six months of 2018 also reflects the positive effect of colder weather and customer growth on sales volume of $2 million and lower revenue of $2.5 million to account for the reduction in rates due to the lower corporate income tax rate of 21% under the TCJA. The reduction in revenues related to the TCJA also reflects a lower in offsetting provision for income taxes in the period. Natural gas therm sales increased 2.8% and 7.2% in the three and six month periods respectively compared to the same periods in 2017. The increase in gas therm sales and the company service areas was driven by customer growth and for the six month period colder weather in 2018 compared to 2017. There were 9% more heating degree days in the first six months of 2018 compared to the same period in 2017. The company estimates that weather normalized gas therm sales excluding decoupled sales were up 2.8% in the first six months of 2018 compared to the same period in 2017. As of June 30, 2018 the number of total natural gas customer served has increased by approximately 1,550 in the last 12 months or about 2%. Next, turning to Slide 11; electric sales margins were $22.3 million and $44.6 million in the three and six months ended June 30, 2018 which reflects decreases of $1 million and $0.7 million respectively compared to the same periods in 2017. Electric sales margin in the first six months of 2018 was positively affected by higher electric distribution rates of $1.7 million, as well as colder weather and customer growth of $0.5 million, partially offset by non-recurring adjustment that was in the second quarter of 2017 but not recorded this year that increased revenue by $1.4 million in '17 to reconcile temporary rates to the company's New Hampshire electric utility which were effective July 1, 2016. Electric margin also reflects lower revenue of $1.5 million in 2018 to account for the reduction in rates due to the lower corporate income tax rate of 21% under the TCJA. The reduction in revenues related to TCJA also reflects a lower and offsetting provision for income taxes in the period. Total electric kilowatt hour sales increased 3.3% and 4.6% in the three and six month periods ended June 30, 2018 compared to the same periods in 2017 reflecting customer growth, higher usage by C&I customers and an improving economy, and the positive impact of colder winter weather for the six months period. As of June 30, 2018 the number of total electric customers served has increased by approximately 600 in the last 12 months. Now turning to Slide 12, excluding the non-recurring adjustment to increase operation and maintenance expenses by $1.2 million in the second quarter of 2018 which was offset by a corresponding increase in gas revenue as I just highlighted in the margin discussion, total O&M expenses increased $0.1 million and $1.4 million for the three and six months ended June 30, 2018 compared to the same period in 2017. The increase in the three month period reflects higher labor cost of $1.1 million offset by lower professional fees of $0.8 million and lower utility operating cost of $0.2 million. The increase in the six month period reflects higher labor cost of $1.8 million, and higher utility operating cost of $0.4 million offset by lower professional fees of $0.8 million. Depreciation and amortization expense increased $0.8 million and $0.6 million in the three and six months periods respectively compared to the same periods in 2017. These increases reflect higher utility plant and service and higher amortization of software costs, partially offset by lower amortization of deferred major storm costs which are being amortized for recover over multi-year periods. For the six months ended June 30, 2018 taxes other than income taxes have increased $0.3 million compared to the same period in 2017, this increase reflects higher payroll taxes corresponding to higher labor cost. Interest expense net increased $0.6 billion in each of the three and six months ended June 30, 2018, compared to the same periods in 2017. These increases primarily reflect interest on higher levels of long-term debt. In the first quarter I mentioned the adoption by the company of ASU number 2014-09 which affected the presentation of revenues for Usource, our non-regulated energy brokering business prospectively only. This accounting standard requires that payments made by Usource to third-parties, or what we call channel partners for revenue-sharing agreements, are recognized as a reduction from revenue where those payments were previously recognized as an operating expense. This prospective change for Usource revenues and the primary driver of the decline in revenues shown in our financial statements for Usource. Lastly, federal and state income taxes decreased by $2.2 million and $5.1 million for the three and six months ended June 30, 2018, compared to the same periods in 2017. The decrease in the three month period reflect $1.7 million from the lower tax rate on a lower pretax earnings in 2018, and the current tax benefit of $0.5 million on book tax, temporary differences turning at the lower income tax rate from the TCJA in 2018. The decrease in the six month period reflects $4 million from the lower tax rate on the lower pretax earnings in 2018 and the current tax benefit of $1.1 million of book tax temporary differences turning at the lower income tax rate from the TCJA in 2018. Looking forward for the remainder of 2018, we expect to maintain a lower effective income tax rate in a range of 18% to 21%. Slide 13 gives a brief summary of our financial position. We had strong investment grade ratings with a balance 50-50 equity-debt capital structure. We are well positioned to lower our weighted average cost of capital by financing higher cost long-term debt over the next five years as we refinance over $80 million of maturing long-term debt. We're also pleased that yesterday we entered into a new credit agreement; the second amended and restated credit agreement which provides for a new five year maturity date out to July of 2023. We also implemented an extension option where we can extend the maturity of the facility for one year upto two additional times. We increase the coordinate [ph] feature of the facility from $30 million to $50 million to provide ample liquidity for future growth initiatives. Lastly, we attained improved pricing from LIBOR plus 1.25% to LIBOR plus 1.125%, about 12.5 bips improvement which reflects continued improvements in our financial and credit statistics. Slide 14 provides a trailing 12 months actual earned return-on-equity in each of our regulatory jurisdictions. Unitil on a consolidated basis earned a total return on equity of 10.1% in the last 12 months ended June 30, 2018 which is in line with our authorized returns. I point out that these results are not weather normalized; we have a constructive regulatory environment that is supportive of growth initiatives and investments to provide our customers with safe and reliable service. We have long-term plans or cost trackers established across nearly all of our utility subsidiaries. The chart also provides a summary of the impact of recent federal tax legislation on each of our regulated utilities which have been fully approved by all our regulators. During the second quarter of 2018 we received approval for our New Hampshire gas utility rate case providing for $2.6 million annual increase in revenue partially offset by a TCJA reduction of $1.7 million. In that rate case we were also awarded a capital tracker mechanism with $2.3 million approved effective May 1, 2018. For the remainder of our jurisdictions, we've shown capital tracker rate adjustments, as well as the impact of the TCJA for this year. Now, this concludes our summary of our financial performance for the period. I will turn the call over to the operator who will coordinate questions. Thank you.
