Good morning and as always thanks to each of you for your continued interest and investments in BSY. I will start by relating the directions reflected in our 2023 results to our consistent expectations for 2024 and then some developing aspects, which also have a bearing on our outlook. Nicholas will cover operational highlights of the quarter, including soundings of the current tone of business on every front, and Werner will review financial details for both years, all the way through cash generation and its planned allocation. Most significantly, I must emphasize our overall satisfaction with Q4 and the full year 2023. In keeping with this, Nicholas and his operating teams are to be enthusiastically congratulated for performance, which while surpassing our established annual hurdle of 100 basis points improvement in operating margin including stock-based compensation, earned 100% of their new business-based incentive pool. Although this entailed resourceful rebalancing after new mining investment unexpectedly slowed down in midyear, we have ended the year with historically high momentum in our fundamental ARR growth. A quarter ago a key question about ARR growth for 2023 Q4 was the degree to which accelerating progress in transitioning our China commercial model to be less directly subscription-oriented could perversely offset overall ARR growth. Otherwise, always our best performance gauge across the remaining 97% of our world. Indeed China, which previously was an ARR growth contributor, has been the significant detractor from our ARR growth as shown here ever since sanctions on Russia coincided with geopolitical apprehension about American software subscriptions for Chinese state-owned infrastructure enterprises. In 2023 Q4, our purposeful structural changes in China did seem to be making progress. When Chinese developed products of our first joint venture cannibalized project-wise installations, we lose ARR in exchange for approximately equivalent one-time net proceeds of the license sale for our underlying platform. But with no American stigma, hopefully, volume expands so that we can come out ahead. In fact, we concluded 2023 by growing our revenues in China for the year by 3% as such licenses more than offset the inevitable decline 7% in China ARR. To quantify the increasing impact on ARR of this intentional China market change, our overall ARR year-over-year growth rate of 12.5% is increasingly diverging from our high of 13.5% in the quarter for the world excluding China. And given the acceleration in our business benefiting the ARR detracting transitions in China, the baseline ARR growth rate for our 2024 outlook must reflect this gap prevailing foreseeable. To further consider how the other directions within our growth momentum exiting 2023 should inform our 2024 financial outlook, let's review in turn each of the underlying factors that we portray notionally in our introductory materials as layers within ARR growth. Starting at the top with new business from new logos, in 2023 Q4 for the fifth straight quarter this accounted for about 3% in ARR growth, led by our SMB initiative and ongoing digital experience investments towards self-service automation. Reinforcing confidence in continued such momentum in 2023 Q4 Virtuoso subscriptions attracted over 700 further new logos for the eighth straight quarter of over 600, in addition to over 400 separate new logo SMB accounts where in 2023 Q4 we achieved what I suspect was a competitive displacement through a perpetual license sale. The other layers of growth are those which aggregate to our net revenue retention for existing accounts. Because NRR takes into account only recurring revenue and not license sales, the mix change in China from subscriptions to licenses, is increasingly impinging on this measure. So while NRR declined in 2023 Q4 to 109%, excluding China and Russia, which is also a factor now, as this looks back over the full trailing two years, NRR would have remained at 110%. Our most significant initiative to sustain NRR accretion is our E365 consumption subscription program for enterprise accounts. You see here in green the incremental magnitude and proportion of ARR reached through E365 accretion and expansion in 2023 Q4. Although, it being a fourth quarter with its greater concentration of E365 prospect renewals, we upgrade relatively more ARR to 365 than in other quarters. In 2023 Q4, it remained the case that a relatively small portion of E365 growth was from our next largest accounts upgrading to the program with the majority of E365 growth representing NRR within accounts already on E365. E365 renewal negotiations for the largest accounts, now almost always entail resetting the individualized floors and ceilings, which serve to bound what we can charge for the accounts consumption. Increasingly, we and they have preferred to allocate our respective risks of consumption upside and downside proactively progressing over multiple future contract years rather than to renegotiate every year. Our own priority is to maintain floor and ceiling parameters, which in each case enable and incentivize double-digit ARR growth when effectively combining consumption volume, mix and annual pricing escalation. During 2023 Q4, one negotiation resulted for our first time in a total contract value in nine figures USD. Such multiyear E365 arrangement, reinforce our accounts commitment to BSI and to going digital for mutual long-term growth. However, the contract length has no barring on E365's straightforward ratable revenue accounting and annually recurring cash flow. And while much of our non-E365 subscription revenue is subject to 606 vagaries across the quarters of a contract year, we have almost none of the multiyear bookings and/or billings, which caused confounding obscurity for many other peer companies. By contrast over and above the compelling transparency of E365 ratable consumption accounting multiyear floors and ceilings work out to everyone's advantage including investors, because they preserve our incentives and upside while improving and extending the visibility of our ARR, revenue and cash conversion. Back to the outlook for each accretion layer. Our annual price escalation, which can vary by country and product mindful of competitive conditions is on average more or less calibrated to stay ahead of inflation in our own costs, which are primarily for colleague compensation. For each of 2022 and 2023, we realized on weighted average escalation in mid-single digits. For 2024, it must be acknowledged that peak inflation in the world seems behind us, so escalation will contribute less ARR growth going forward. As to consumption volume, we faced another putative headwind with the demographics of retirement tending to reduce the infrastructure engineering workforce. And in theory, increasing productivity through going digital can even be at the expense of usage volume. The only offsetting gains in application usage volume could come from competitive displacement opportunities on the margin. On balance, we cannot now expect nor rely upon net increases in user volume. However, the widening engineering resource capacity gap between a static number at best of infrastructure engineering professionals and the burgeoning demand for world resilience and adaptation is in fact the greatest and most durable driver of our ARR growth, because going digital is the compelling key. Recall that the 2023 year in infrastructure going digital award finalist documented an average of 18% savings in engineering time through the digital advances we enabled for them. Quite noticeably, our enterprise accounts are now explicitly prioritizing E365 blueprint, which most deliver savings and man hours and usage days to our ultimate mutual benefit. And accordingly application mix accretion, which measures the pace of our users upgrading to our more specialized and relatively more costly applications to increase their productivity continues to more than offset demographically constrained usage volume. And accelerating application mix accretion, which is our average revenue per application usage day holding pricing constant for the calculation. Our user success functions especially, by way of E365 digital workflow blueprints are literally leading the way. So, I'm pleased to report accelerating annual progress, with annual application mix accretion having grown from about 4.5% for 2022 to about 6% for 2023. This also captures the usage of ProjectWise attached to these application user days. So, this measure closely corresponds to what we've shown that the ENR top engineering firms, a representative quarter of our business, spend with us. Since that spending only averages about 1% of the amount that they build to their clients for the usage time, I believe there's lots of headroom for application mix accretion to continue to expand indefinitely. And looking to what's new, although we're confident in this long runway ahead for our strong and consistent consumption per user base business, I believe that here in 2024, we're finally at the point where our third aspiring growth initiative after E365 for the enterprise market and virtuosity for SMBs have become firmly established, will finally take off after having been promised in our intro deck as you see here for years. This third growth initiative leverages Digital Twin opportunities to be incrementally monetized, through cloud subscriptions charged per asset. While I think that by rights, this can grow to become larger than the provision of software per user, the challenge has been that scaling Digital Twins takes a surrounding ecosystem of digital integrates to provide the related services around data quality and engineering proficiencies, which complete the use cases. To that end, we along with others have been determinedly evangelizing the infrastructure Digital Twin potential, spanning delivery and performance to thus both the infrastructure project delivery supply chain and of course to owner operators directly. Frankly, institutionalized conservatism has made this a slow sales cycle, with success by the ones and primarily in Asia Pacific. To gain experience in the meantime, we have assembled our own cohesive digital integrator to show the way. It's now nearly $100 million services business is opportunistically anchored by being the leading global implementer and emerging cloud hosting provider of IBM's Maximo, the primary incumbent choice of infrastructure owner operators for enterprise asset management. Thus, over time, cohesive can open doors for our iTwin platform to integrate engineering technology ET and operational technology OT with Maximo's IT for Digital Twins to optimize operations and maintenance. This represents the extreme of an enterprise approach to Digital Twins from the top down. But because that takes so long, we are trying also to widely catalyze Digital Twin opportunities from the bottom up. Hence, our priority to infuse and connect all of our existing offerings with our iTwin platform, starting with our Bentley Infrastructure cloud, ProjectWise and SYNCHRO for delivery and AssetWise for performance, and this year with natively hybrid capabilities in our modeling and simulation applications. However, even this is, at best, an evolution toward Digital Twin workflows. So, I am very pleased to say that we have now validated a breakthrough bottoms-up entry point for Digital Twin monetization that is, by contrast, instant on both technically and commercially. Accordingly, our main departure for 2024 will be a focus on this asset analytics opportunity. It leverages AI with our iTwin platform to generate discrete and actionable insights from enlivened reality modeling of infrastructure assets with the Digital Twin OT uniquely enhanced by ET and IT. Our learning curve in asset analytics was initiated with OpenTower, which we developed around a small acquisition of cell tower specific AI for our structural modeling and iTwin platform. Since I showed this with operating results almost two years ago, the AI value to communications operators for CapEx provisioning and OpEx inspection and maintenance has grown exponentially. What is new are the global household names in the broadband infrastructure ecosystem looking to join forces to institutionalize cell tower Digital Twins. Our other foray to-date in asset analytics Blyncsy, acquired and described late last year where the monetized asset is a mile of roadway and what we charge depends on how frequently the AI is run on fresh crowdsourced imagery to detect actionable maintenance conditions. Because its crowdsourcing is ubiquitous, Blyncsy asset analytics can be literally instant on in a blink. In each asset analytics case, our role can be behind the scenes providing the iTwin experience cloud services, our AI-as-a-Service, and all of the automated processing at scale and at standard volume-based pricing. Ecosystem partners can variously bundle and provide the survey imagery, their own proprietary asset-specific engineering analytics, and enterprise integration with the owner-operators environment. The financial opportunity is here and now. Our ARR for Asset Analytics Cloud service is in three digits per cell tower. In 2023, Q4 OpenTower won procurements including for new business ARR in seven digits. And in 2024, we are competing for eight-digit subscriptions. And with our go-to-market coverage of transportation owner operators, Blyncsy is now also pursuing procurements that can exceed seven figures of ARR. In each of the cell tower and roadway verticals, it is thus already clear that there is an asset analytics TAM in nine figures. And on our existing global footprint gives us the pole position with both the owner-operators and the required ecosystem partners. So, for 2024 our investment focus will be to organizationally consolidate OpenTower and Blyncsy with further potential such acquisitions for growth and operational synergies and to leverage and expand our asset analytics head start. This will have a higher priority than continuing either our iTwin venture program or fractional investments or even our traditional programmatic acquisitions of known mature companies to fill white space in modeling or simulation. As there don’t tend to be potential asset analytics acquisitions beyond early-stage companies, the capital requirement should fit well within what would have otherwise been the magnitude of our historical programmatic acquisitions. And while OpenTower and Blyncsy themselves merit rapid investment to add capacity within their ripening markets, this is already sufficiently accommodated in our 2024 outlook for operating margin, including stock-based compensation, which continues our consistent annual improvement target of 100 basis points. Moreover, to the extent, we succeed in making further acquisitions and asset analytics and thus presumably end up actually for accounting, consolidating early-stage losses, which would have been below the line had we been merely DC investing to fund them, we will commit to corresponding increases in our ARR growth rate, so that BSY's literal Rule of 40, if you do the math for 2024 is not significantly in jeopardy this year. So while I have been generally emphasizing, maintaining into our 2024 outlook, our favorable overall operational and market consistency and momentum from 2023, this significant change to our acquisition priorities will make a difference. As you see here, the contribution to our business performance of ARR acquired with programmatic acquisitions had already been declining to a new loan in '23 Q4. But since in 2024, we will be targeting Asset Analytics acquisitions, which will necessarily be in early stages, this layer will probably end up more ARR right than ever before. This is reflected in our 2024 outlook for ARR growth business performance, which is in the range of 10.5% to 13%. Nominally, that appears below what was our outlook for 2023 a year ago and at the midrange below our 2023 actual outcome. But in fact, we plan for a quite consistent underlying robust ARR growth, especially ex-China, but subject as measured though to these effects of the accelerating China subscription transition of somewhat moderated escalation and have lowered expectations for ARR from programmatic acquisitions. Finally, the wider range than 2023 reflects the greater variability in the emerging Asset Analytics business model. To summarize, we are responding to very healthy end markets with appropriate and by now proven initiatives to sustain 2023's performance with incremental upside now including Asset Analytics. And any case, I think you can take away confidence in our principal demonstrated investment premise, consistently delivering profitability after stock-based compensation, which has grown at a compounded rate remaining on the order of 16% per year since 2018, with distinctively transparent cash conversion. And now, over to Nicholas, for operational perspectives behind these directions and development. Thank you.
