Retirement Benefits [Abstract]  
Pension Benefits PENSION BENEFITS
Certain of Aptiv’s non-U.S. subsidiaries sponsor defined benefit pension plans, which generally provide benefits based on negotiated amounts for each year of service. Aptiv’s primary non-U.S. plans are located in France, Germany, Mexico, Portugal and the United Kingdom (“U.K.”). The U.K. and certain Mexican plans are funded. In addition, Aptiv has defined benefit plans in South Korea, Turkey and Italy for which amounts are payable to employees immediately upon separation. The obligations for these plans are recorded over the requisite service period.
Aptiv sponsors a Supplemental Executive Retirement Program (“SERP”) for those employees who were U.S. executives of the former Delphi Corporation prior to September 30, 2008 and were still U.S. executives of the Company on October 7, 2009, the effective date of the program. This program is unfunded. Executives receive benefits over five years after an involuntary or voluntary separation from Aptiv. The SERP is closed to new members.
The amounts shown below reflect the defined benefit pension expense for the three and six months ended June 30, 2025 and 2024:
