The 2025 Enduring Retirement Model Study is a comprehensive report that examines employers' perspectives on retirement benefits in the United States. It outlines the evolution of retirement plans, particularly the shift from defined benefit (DB) plans to defined contribution (DC) plans, and the implications of this transition for workers. The study highlights the ongoing commitment of employers to provide retirement benefits, despite the decline of traditional DB plans. It also discusses the changing retirement patterns of an aging workforce, noting that many older workers are delaying retirement due to financial necessity. The report emphasizes the importance of redefining retirement in light of these trends, including the rise of gig work and phased retirement options. Additionally, it presents findings on the expected impact of economic conditions and artificial intelligence on the future of retirement benefits. The methodology includes surveys and interviews with plan sponsors and industry experts, providing a robust analysis of the current retirement landscape.
