Thank you, Greg. Our Q4 results included revenue of $2.3 billion, down 4% including $60 million from acquisitions and $19 million from favorable currency rates. GAAP operating earnings of $555 million and operating margins of 24.4% compared to 24.8% in the year ago quarter. Non-GAAP operating earnings of $667 million, down $40 million or 6% and non-GAAP operating margins of 29.3%, down from 29.7%, due to lower sales in the Products and SI segment, partially offset by higher sales and improved operating leverage in Software and Services. GAAP earnings per share of $2.37 compared to $1.39 in the year ago quarter. The increase was primarily due to a noncash charge of $1.53 booked in Q4 of 2019 related to the actions taken then to derisk our pension. Non-GAAP EPS of $2.86 versus $2.94 last year, down primarily due to lower sales from Products and SI, partially offset by higher sales and improved operating leverage in Software and Services. OpEx in Q4 was $492 million, down $31 million versus last year, primarily due to lower discretionary spend, lower incentives and then partially offset by costs related to acquisitions. The Q4 effective tax rate was 21% compared to 22% in the prior year. Moving to the full year 2020. Our revenue was $7.4 billion, down 6% primarily related to lower sales of public safety LMR and PCR products, partially offset by growth in LMR services, growth in video security and growth in command center software. Revenues from acquisitions was $203 million and currency headwinds were $12 million. GAAP operating earnings were $1.4 billion or 18.7% of sales versus 20% in the year prior. The decrease was primarily driven by lower sales from Products and SSI, partially offset by higher sales and improved operating leverage in Software and Services. Non-GAAP operating earnings grew $1.8 billion, down $140 million and non-GAAP operating margins were 24.8% of sales, a decrease of only 20 bps despite the sales declines in Products and SI, driven by the actions we implemented around costs, lower incentives and growth in Software and Services. GAAP earnings per share was $5.45 compared to $4.95 in the prior year, which included the previously mentioned noncash charge for pension. Non-GAAP EPS was $7.69, down 3% from $7.96 in 2019 on lower sales and operating earnings, partially offset by a lower effective tax rate and a lower diluted share count in 2020. For the full year, OpEx was $1.8 billion, down $162 million from last year, primarily driven by lower incentives, lower discretionary spend and offset by $75 million from acquisitions. And the effective tax rate for 2020 was 20% compared to 22.4% in the prior year on higher R&D tax credits and higher tax benefits from share based compensation recognized in the current year. Turning to cash flow. Q4 operating cash flow was $703 million compared with $795 million in the prior year, and free cash flow was $637 million compared with $736 million in the prior year. For the full year, operating cash flow was $1.6 billion compared to $1.8 billion in the prior year and free cash flow was $1.4 billion versus $1.6 billion in the prior year. The decrease in cash flow was driven by lower sales and higher cash taxes in the current year, partially offset by improvements in working capital. Capital allocation in 2020 for us included $612 million of share repurchases at an average price of 155 and $0.93 per share, $436 million in cash dividends and $287 million for acquisitions. Additionally, during the year, we refinanced outstanding debt maturities with a new $900 million 10 year debt issuance at a rate of 2.3% and raised our dividend 11%. Moving to our segment results. Q4 products and system integration sales were $1.5 billion, down 10% primarily due to lower sales of public safety LMR and lower sales of professional and commercial radio partially offset by growth in video security. Revenue from acquisitions in the quarter was $44 million. Operating earnings were $408 million or 27% of sales, down from 28.9% in the prior year on lower sales. Some notable Q4 wins and achievements in this segment include $122 million P25 order for Nassau County, New York, a $61 million P25 order for state of New Jersey, over 50 million of P25 orders from several large North America utilities customers, a $26 million P25 order from Morris County, New Jersey, and a $20 million tetra order in the UK. Additionally, we had another quarter of double digit growth in fixed video sales into our government customers. For the full year, revenue in the segment was $4.6 billion, down 13% in the prior year, driven by lower sales of public safety LMR and PCR, partially offset by growth in video security. Revenue from acquisitions was $119 million. Operating earnings were $880 million or 19% of sales, down from 22% in the prior year on lower sales, partially offset by lower operating expenses. Moving next to our Software and Services segment. Q4 revenue was $763 million, up 8% from last year, driven by growth in LMR services, growth in video security and growth in command center software. Revenue from acquisitions in the quarter was $16 million. Operating earnings were $259 million or 33.9% of sales, up 220 basis points from last year, driven by higher sales and improved operating leverage. Some notable Q4 wins in this segment include a $100 million P25 managed services contract with the State of Tasmania, Australia, a $79 million tetra managed services contract extension in Europe, a $30 million P25 multiyear service contract with the Minnesota DOT, a $29 million P25 multiyear service contract with Austin, Texas, and finally an $11 million award for a command center software contract in Norway. For the full year, revenue was $2.8 billion, up 9% on growth in LMR services, growth in video security and growth in command center software. Revenue from acquisitions was$84 million. Operating earnings in 2020 were $955 million or 34.3% of sales, up 290 basis points versus the prior year, driven by higher sales and improved operating leverage. Looking next at our regional results. North America Q4 revenue was $1.6 billion, down 4% on declines in public safety LMR and PCR, partially offset by growth in LMR services, video security and command center software. For the full year, North America revenue was $5.2 billion, down 5% with declines in public safety, LMR and PCR, partially offset by growth in LMR services, video security and command center software. International Q4 revenue was $725 million, down 6% due to declines in public safety LMR and PCR, partially offset by growth in video security and LMR services. Revenues declined in Latin America and Asia-Pac while EMEA was up 2%. And for the full year, international revenue was $2.4 billion, down 8% on declines in public safety LMR and PCR, partially offset by growth in video security, command center software and LMR services. Revenue declined for the year in Latin America and Asia pack while EMEA was flat year-over-year. Moving to backlog. Our ending backlog was a record $11.4 billion, up $175 million compared to last year. Sequentially, backlog was up $753 million, driven by record LMR orders in North America during the fourth quarter. Software and Services backlog was up $213 million compared to last year, driven by multiyear agreements in North America, partially offset by revenue recognition for airways. Sequentially, backlog was up $518 million with growth in both regions. Products and SI backlog was down $38 million compared to last year, driven by delays in sales engagements during the year related to COVID-19. Sequentially, backlog was up $236 million in Products and SI, driven by record LMR orders in North America during the fourth quarter. Turning next to our outlook. We expect Q1 sales to be up between 5.5% and 6% with non-GAAP earnings per share between $1.58 and $1.64. This assumes FX at current spot rates, a share count of approximately $174 million shares and an effective tax rate of approximately 19%. And for the full year, we expect sales to be up between 7.25% and 8% with mid single digit growth in Products and SI and low double digit growth in Software and Services. And we expect full year non-GAAP EPS between $8.50 and $8.62 per share. This assumes FX at current spot rates and a share count of approximately 174 million shares and an effective tax rate of 22.5% to 23%. We expect full year operating cash flow of approximately $1.8 billion, which includes an unfavorable year-over-year impact of approximately $125 million related to higher cash taxes. And we expect full year OpEx to be approximately $1.9 billion, which includes a year over year increase of $75 million related to higher incentives as we plan for growth and $60 million related to acquisitions closed in 2020 offset by further cost reductions. Finally, I'd like to highlight that we are updating our reporting to incorporate an enhanced disclosure around our three major technologies across both segments. As a result in our forthcoming 10-K, you will see net sales in our two segments reported in the following three technologies, LMR mission critical communications, video security and analytics, and command center software. We have provided a supplemental slide in the back of our earnings presentation, representing this view for the previous three years and on an ongoing basis, we will incorporate this into our quarterly reporting. I would now like to turn the call back over to Greg.
