Greg Case -- Chief Executive Officer

Thank you and good morning, everyone. Welcome to our fourth quarter conference call. I'm joined by Christa Davies, our CFO; and Eric Andersen, our president. As in previous quarters, for your reference, we posted a detailed financial presentation on our website.

We begin today by thanking Aon colleagues around the world. Our strong performance in the fourth quarter through 2022 and our strong momentum as we start 2023 continues to reflect tremendous dedication by our colleagues and the power of our Aon United strategy to support clients, both in their demands of the day and as they plan to address their needs of tomorrow. 2022 was a year in which we continue to see clients focus on both the challenges and opportunities from increasing global risk and the opportunities to engage clients continues to grow. In commercial risk, our latest Weather, Climate, and Catastrophe Insight report cites global economic losses from natural catastrophes at 313 billion, 4% over the 21st-century average; and with only 42% covered by insurance, 190 billion protection gap.

In wealth solutions, equity and fixed-income market volatility in the back half of the year created a demand for our wealth solutions colleagues' [Inaudible] reassess retirement readiness and financial well-being. And in health solutions, which includes our human capital business, the continuation of broad trends around a changing workforce, encompassing health, culture, wellness, engagement, and inclusion, are growing in focus and importance across the C-suite, and the stakes have never been higher. In this environment of increasing risk and complexity across so many fronts, our colleagues are increasingly relying on Aon United. It's what enables them to bring the full force of our firm, including core offerings and innovative solutions at scale, to address evolving client demands.
