Thank you, John. I’ve planned to provide a summary of our 2015 operating results and recap the primary factors impacting the change from 2014. And also comment on some expectations around 2016, so let’s move to the slides. Consolidated net income for 2015 came in at a $138 million or $2.94 per basic share that compared to $141 million or $3.04 in 2014. Our Construction Services segment showed strong improvement between years, while our gas segment results declined. Operationally, the gas segment declined was fairly modest. However, returns on investments underlying company-owned life insurance or COLI policy fell by $5.8 million between years and was the primary reason for both the overall gas segment and consolidated earnings decline. Taking that into account, 2015 compares favorably to 2014. Let’s move to slide six in the natural gas segment highlights. In addition to the items, John mentioned earlier, highlights included operating margin growth, reduced financing costs of $4.2 million between years and successes we’ve had on the regulatory front, which Justin will discuss later on. Slide seven, this slide summarizes in the gas segment. Operating margin increased by $14 million between 2014 and 2015, all operating expenses increased by $21 million or 3.3%. As a result, operating income declined by $7 million between three. Net interest deductions favorably offset the operating income decline by $4.2 million. But other income was substantially lower than last year, when COLI returns were quite favorable. That result was a decrease in the gas segment contribution to net income from $117 million in 2014, to $112 million in 2015. Now slide eight summarizes the change in operating margin between years. Customer growth contributed $8 million as the company increases customer account by 26,000 over the last 12 months. Combining rate release in California and from pipeline provided $5 million in operating margin. For 2016, we expect an overall operating margin increase of about 3% from customer growth, California rate release, margins from our infrastructure tracking mechanisms and the Elko expansion project. We also expect another $11 million to recover deferred conservation cost in Nevada, for which there will be a direct offset in amortization expense. On slide nine and 10 relates to our operating expenses. Operating expenses increased $20.9 million or 3.3% between 2014 and 2015, which was on the lower end of our initial forecast range of 3% to 4%. There were several main factors influencing operating expenses in 2015. O&M expenses were up 2.5%, nearly all of which was driven by a higher pension costs, resulting from a new mortality table adopted last year. Our other O&M cost on a net basis were pretty well flat. Depreciation expense increased 5% and general taxes 5% as a result of the 5% growth in gas plant. During 2015, the company invested $438 million of gas system, up from $350 million in 2014 and our highest single year capital expenditure level in history. Looking ahead to 2016, relatively flat O&M costs coupled with higher depreciations and general taxes from continued investment in our distribution system are expected to result in an overall operating expense increase in the range of 2% to 3% plus the $11 million amortization described previously. Slide 10 please. Other income declined from $7.2 million to $2.3 million between years, as 2015 returns on investments underlying our COLI policies were slightly negative, while 2014 returns were strong at $5.3 million. Investments underlying COLI policies include a blend of debt and equity mutual funds; whose combined returns were relative flat consistent with the broader investment market landscape. As a reminder, we think annual average COLI returns in the range of $3 million to $5 million will represent a normal level, but these returns are influenced by market forces and therefore subject to volatility. On the next slide, we'll look at financing activity. Net financing costs decreased by $4.2 million between years. This primarily resulted from the early redemption of $116 million of industrial development revenue bonds since November 2014 that was driven by healthy cash flows particularly those related to gas cost recoveries. For 2016, we anticipate some incremental financing later in the year to support our capital expenditure program. Consequently, interest expense is expected to increase over 2015 levels. Next, we'll turn our attention to the Construction Services segment starting at slide 12. Our Construction Services segment had another very good year in 2015. Revenue exceeded $1 billion for the first time and net income reached a new high watermark at $26.7 million. Favorable weather through most of the fourth quarter allowed us to extend the construction season on the East Coast, Midwest and in Canada helping drive the revenue milestone. And also as John mentioned, we reached the final settlement on the industrial project in Canada, reducing our previously accrued pretax loss from $7.7 million to $3.4 million. Revenues in construction costs associated with the project are included on the slide. Slide 13 provides a snapshot of the Centuri income statement over the last three years. The trend line for all significant line items is very favorable to reflect solid organic growth as well as full year results from the companies acquired in October 2014. The next we'll walk through the line item changes, starting with revenues on slide 14. Construction revenues increased from $740 million in 2014 to $1 billion in 2015, an improvement of $269 million or 36%. Acquired company’s revenue accounted for $124 million of the revenue increased, while growth of replacement work from existing NPL customers was responsible for the remaining $145 million. For 2016, we estimate an operating revenue growth in the range of 3% to 7%, assuming a return to more normal weather conditions and returning to the 7% and 10% range thereafter. Operating income as a percentage of revenue is expected to be between 5.5% or 6%. Moving to slide 15, construction expense increased by $251 million or 39%. Acquired company construction cost accounted for $115 million of the increase and cost associated with additional pipe replacement work at legacy NPL accounted for the remaining $136 million. Also contained within the construction expense increase were 9 million of higher G&A costs. Nearly all of which was attributable to having a full year of operations of the acquired companies. And finally, depreciation expense increased $8 million between years and included an incremental 3 million related to the amortization of finite-lived intangible assets recognized in the acquisition and 4 million of incremental depreciation at the acquired companies. With that, let me turn the time over to Justin Brown.
