Thanks Brian. Please refer to Slides 2 through 6 as I provide some explanations and details of our financial results. Fourth quarter revenue was $720 million, an increase of $131 million or 22% compared to the fourth quarter of 2018. This increase is due to the acquisition of Walker, which is reported in our Electrical segment. Same-store revenue was off slightly, declining 1% for the fourth quarter. Revenue for full year 2019 was $2.6 billion, an increase of $432 million or 20% compared to 2018 and most of that increase was related to the Walker acquisition. On a same-store basis, revenue in 2019 was 2% higher than in 2018. Gross profit was $133 million for the fourth quarter of 2019, an increase of $14 million or 12% compared to the fourth quarter of 2018. Gross profit as a percentage of revenue was 18.4% in the fourth quarter of 2019, compared to 20.1% in the fourth quarter of 2018. For the full year of 2019, gross profit increased $56 million and the gross profit margin was 19.2% in 2019, compared to 20.4% in 2018. Of the $56 million increase in gross profit that we reported this year, $35 million was earned in our Electrical segment. Our Electrical segment business mix is weighted to large and complex projects with significant amounts of material and equipment pass through costs, and therefore tend to have lower average gross profit margins. Our Electrical segment also had less service revenue and that also correlates with lower gross profit margins and lower SG&A percentages. Additionally, because our Electrical segment in 2019 was created by a single large acquisition that occurred within the year, acquisition related adjustments for the transaction lowered the gross margins reported for our Electrical segment. For the fourth quarter of 2019, Electrical segment gross margin would have been over 3% higher without those adjustments. And for the full year 2019, Electrical segment gross margins would have been over 2% higher on an annual basis without the acquisition related adjustments. Without our Electrical segment, our full-year gross profit percentage would have been 20.7%, a difference of 1.5% that arises from a combination of the lower gross margins in their business mix and certain purchase adjustments that I just mentioned and that impact our gross margins. With these larger projects and less service, Walker has lowered our SG&A percentage. Net income for the fourth quarter of 2019 was $34 million or $0.92 per share as compared to $25 million or $0.67 per share in 2018. We recorded a gain of $0.08 per share in the fourth quarter of 2019, due to insurance proceeds we received to reimburse us for lost productivity and other hard and soft costs incurred earlier this year, as a result of the cyber incident we suffered in April 2019. Approximately, $1.6 million of the gain was recorded as a reduction of SG&A and the remainder was recorded as a reduction to cost of services. We do not expect any additional insurance proceeds or other recoveries related to that incident. Our full year earnings per share was $3.08 per share in 2019, compared to $3 per share in the prior year and so we had another record year. For the full year, EBITDA was $214 million, compared to $192 million for the prior year. The increase in EBITDA is primarily due to the Walker acquisition in our new Electrical segment. Our overall SG&A expense was $87 million for the fourth quarter of 2019, compared to $80 million for the fourth quarter of 2018. The dollar increase in SG&A was a result of our Walker acquisition, including additional amortization expense. We had good SG&A leverage in the fourth quarter, as SG&A had a percentage of revenue for the fourth quarter of 2019 that declined to 12% compared to 13.7% for the fourth quarter last year. SG&A in the fourth quarter was helped by the insurance recovery we mentioned, and we also had lower incentive compensation expense. For the full year, SG&A as a percentage of revenue was 13.0%, compared to 13.6% in the prior full year. The overall improvement in the SG&A percentage was as explained earlier, largely due to the Electrical segment, which as larger projects requiring proportionately lower levels of SG&A. Our 2019 tax rate was 24.7%, compared to 24.1% in 2018. The 2018 tax rate benefited from a discrete tax item, while the 2019 tax rate benefited from discrete benefits from the energy efficient commercial building production, also known as a 179D deduction. We currently estimate our future effective tax rates will be between 25% and 30%. However, our effective tax rate in 2020 could tend toward the lower end of this range due to the recent extension of that same 179D deduction, that's now been extended through the end of calendar 2020. Cash flow for 2019 was strong and our full year free cash flow was $112 million compared to $122 million in 2018. This strong cash flow has allowed us to pay down our debt by over $70 million between the Walker acquisition on April 1 at the end of 2019. We feel great about our cash flow prospects for 2020 and we're also happy to announce another dividend increase this quarter. This makes the seventh consecutive year that we have increased our dividend. As Brian mentioned, we amended our credit facility in December to increase the amount available by $200 million to a total of $600 million. We're happy to have been able to lock-in favorable pricing, as well as financial covenants that recognize our strength and reward our conservative long-held approach to balance sheet management. We also procured even more flexibility to complete transactions and return capital to our stockholders. Above all, our amended agreement now expires in January 2025 and thus gives us good visibility and stability, as we continue our strategic investments. During the fourth quarter, we purchased 84,000 of our shares at an average price of $50.27. In 2019, overall, we purchased 429,000 shares over the course of the full year. Since we began our stock repurchase program in 2017 and bought back 8.6 million shares at an average price of $17.70, directly returning over $150 million to our shareholders. That's all I have on financials, Brian.
