Thank you, Pat, and good morning, everyone. I'll start on Slide 7 with our load growth by service area, with PNM first. Load grew at 2.9% in the fourth quarter compared to the prior year with growth coming from all customer classes. For most of 2022, we saw residential and commercial load growth above our expectations, while industrial customer expansions were delayed by supply chain and related market issues. We expect the growth we saw in the fourth quarter to continue into 2023 between 2% and 3%. We're still seeing the results of New Mexico's economic development efforts through our customer expansions. We also see government and tribal projects that are less impacted by market-wide economics. At TNMP load growth in 2022 exceeded expectations for both volumetric and demand based load plus the added growth from crypto mining customers entering the market. These customers are mostly in our West Texas service territory providing some economic diversity to the region. Our operations in North Central Texas and the Gulf Coast, provides strong geographic and economic diversity to TNMP, and each of those areas support a mix of business operations and growing residential and commercial communities surrounding the nearby larger cities. For 2023, volumetric growth is expected at 2% to 3% consistent with the full-year results of 2022. Demand based growth is expected at 3.5% to 4.5% above the 2022 levels. Now turning to Slide 8. I'll cover the ways we've been taking care of business at PNM and making progress on our strategic objectives. The transformation of our generation portfolio has been front and center. We have plans to exit coal and reach carbon free electricity by 2040 five years ahead of the New Mexico mandate. The closure of San Juan Generating Station this year was a significant step in achieving these goals, reducing the amount of coal in our portfolio and advancing us to 55% carbon free capacity. Our next big step is exit of our ownership stake in Four Corners Power Plant and completely eliminate coal generation from our portfolio, which we are still pursuing for the end of 2024. As you can see in the pie charts, we are replacing these resources with renewable and batteries storage after working through the 2022 delays for PPA developers, we expect 350 megawatts of solar and 170 megawatts of battery storage coming online in 2023. At that point, over half of our resource portfolio will be renewables and storage. And with our continued ownership of Palo Verde, we will hit 61% carbon free capacity. These changes provide significant benefits for the environment and our communities and also financial benefits for customers, which I'll cover in a minute. Another key to successful transition towards a carbon free portfolio is T&D infrastructure. Investments in our grid provide the foundation for serving the growing demand on PNM system and maintaining reliability. The peak demand on our system has been growing at a faster rate than our total load and we hit a new system peak in 2022, our first since 2013. Our focus has been on strengthening the infrastructure that directly serves customers, substations in lines are being reconfigured to accommodate new customers along with customer owned resources. We are building the system to be more resilient and reduce outage restoration time. Other T&D investments at PNM relate to grid modernization projects. We filed our comprehensive grid modernization plan to implement smart meters and other projects that will lay the groundwork for future improvements and provide our customers with more resilient grid. When we look ahead, we see the need for expansion of our system, our change in generation resources, means that transmission capacity tied to existing plants can be used for the replacement options. But as the resource needs grow beyond these replacements, new transmission capacity will be needed to facilitate additional resources across the state. Now turning to Slide 9. I'll walk you through the key regulatory proceedings tied to these investments. As Pat mentioned, in December, we filed our first PNM rate review in six years. PNM customers already benefit from having lower bills and much of the country and we worked to balance the need for investments in our system with the impacts on customers, The Energy Transition Act was designed to facilitate the transition to clean energy while reducing cost to customers and this rate filing showed that it is working as intended. The filing in -- the filing is a 2024 future test year, so it rolls forward our rate base for the full six years and incorporates current cost trends. The retirement of San Juan and the return of the Palo Verde leases reduces the requested recovery in base rates and also reduces the cost recovered through our fuel cost, as replacement resources come online. Securitization provides for lower financing costs as we make this transition all in the proposed bill impact in 2024 is limited to 0.9% or $0.75 per month for the average residential customer. The procedural schedule in this case calls for intervener testimony, seller settlement filing by May 12 and hearings scheduled in June. The schedule for our grid modernization filing includes hearings scheduled in March. Remember that we have asked for approval of our project plan by July 1 of this year, but we delayed our requested implementation date of the rate rider until September 1, so that it would not be added to summer bills this summer, when the usage is typically higher. We also prioritized low income customers and communities in our filing, these are the customers most in need of tools to manage their usage and bills and it also makes sense to bring improvements to these areas first. Also in March, the New Mexico Supreme Court has scheduled oral arguments and our proposed exit from Four Corners Power Plant in December of 2021, the commission rejected our filing to exit our ownership share of the plant and securitize our undepreciated investments. The briefing schedule was completed in 2022 and we are looking forward to the oral arguments for further opportunities to present our case. Now turning our attention to TNMP on Slide 10. Our focus has been to maintain investment levels to keep up with the pace of growth. The rate base doubled over the course of five years with another strong year of investments planned for 2023. The needs range from serving new residential subdivision to connecting new chemical plants. The regulatory environment in Texas continues to support these investment levels. We have made use of semiannual transmission recovery filings along with annual distribution recovery filings. In January, we made our first transmission filing for 2023 requesting over 150 million of project cleared by December of last year, We would expect to recovery to be approved and implemented by March of this year. With that I will turn it over to Lisa to cover the numbers in more depth.
