We generated tangible value for our shareholders and invested in the future by maintaining underwriting discipline, strategically deploying capital, and providing creative risk solutions and superior claims service. At the same time, we completed a multi-year transformation, produced outstanding financial results, enhanced our culture of underwriting and operational excellence, significantly strengthened our balance sheet, reduced our expense structure, and became simpler and leaner. Today, we are a more focused, global general insurance business with an exciting future ahead.
Our most significant accomplishment in 2024 was the strategic deconsolidation of Corebridge Financial – the result of four years of planning, hard work and perseverance. We positioned Corebridge for success by ensuring it had the capabilities to effectively operate as a separate company and establishing a strong investment portfolio operating model, enhanced by a strategic relationship with Blackstone Group and a long-term partnership with BlackRock. Since we announced the separation of our life and retirement business, we secured Blackstone as an anchor investor, executed the largest US IPO of 2022, conducted five secondary market transactions and completed the sale of a 21.6% stake in Corebridge to Nippon Life Insurance Company, reducing our holdings in Corebridge to 22.7% as of year-end.
The deconsolidation of Corebridge enabled us to accelerate our progress on AIG Next, our initiative to weave the company together. We achieved $450 million in exit run-rate savings in 2024 and are on track to reach a parent company expense level of 1% to 1.5% of net premiums earned by the end of 2025. We further connected our businesses, operations and functions and strengthened our operational capabilities, notably in underwriting and claims. We also heavily invested in our data and digital strategies. All of these efforts have positioned AIG for future success in a rapidly evolving environment and sharpened our strategic direction, culminating in the realignment of our general insurance business into three distinct operating segments – North America Commercial, International Commercial and Global Personal.
