The extraordinary improvement in AIG’s gross underwriting performance has enabled outstanding reinsurance outcomes, and this remains the case even in the current environment of heightened risk and reinsurers’ increased discipline. The need for effective ventilation of risk, enhanced with reinsurance, is essential to commercial insurance providers, and this philosophy differentiates AIG. Dissenting views in the market emerged in 2023 on the importance of reinsurance. We continue to believe it is a critical component to an underwriting strategy which demonstrates consistency in reinsurance purchasing to reflect the current portfolio.
We balance disciplined underwriting aligned to the evolving market with the strategic use of reinsurance to mitigate unpredictable outcomes. 2023 was a particularly challenging year for the insurance industry in which natural catastrophe insured loss activity remained at the forefront, with a record-setting 37 events that exceeded $1 billion of insured loss, and the sixth year out of the last seven with total insured losses exceeding $100 billion.***
Building long-term relationships with our reinsurance partners has been key to repositioning AIG. Insurers cannot reverse social and economic inflation. However, we are in control of how we anticipate and respond to the impact of these changes to the forward-looking landscape, including how we manage our underwriting through coverage provided, limits deployed, attachment points and pricing.
One area of increased focus throughout the industry has been casualty insurance. The heightened attention is driven by the increased impacts of rising economic and social inflation, litigation funding, mass tort events and other external forces that increase average severity trends through both legal costs and higher jury awards throughout the industry. Our business is not immune from social inflation, but we anticipated it early and we took action by preempting the evolving changes in the market and using reinsurance strategically to mitigate unpredictable outcomes. We are very pleased with our existing portfolio and we are well positioned to be able to prudently take advantage of opportunities that exist in the current marketplace.
AIG’s global Casualty portfolio represents 14% of General Insurance net premiums written in 2023, with significant reduction in limits across our Casualty lines. In North America Casualty, our gross limit for our Excess Casualty portfolio, including lead umbrella, has decreased by over 50% since 2018 and our average limit size has also reduced by over 50%. Average lead attachment points, which protect us from frequency and lower severity losses, have more than doubled since 2018. We have been closely assessing loss trends in these lines for several years, before Casualty rates accelerated in 2023.
In addition to our underwriting improvement, our journey has entailed a substantial transformation of our operations, including investments in foundational capabilities to modernize our infrastructure, improve end-to-end processes and capture and utilize data more effectively. We performed a significant amount of diligence in 2019 to design and launch an operational program, AIG 200, which we accelerated during the global pandemic. The complexity and scale of this undertaking was significant, but the results were meaningful – we substantially improved our company and we achieved $1 billion of cost savings.
Our improved performance and strategic initiatives have supported our substantial capital management accomplishments. From 2018 through 2023, AIG has completed over $40 billion of capital management actions, consisting of dividend payments, share repurchases and debt reduction.
