The IBM US pension plan has been fully funded (in fact, it has been overfunded) for quite a few years.? As a result, IBM has not had to make contributions to it.? IBM's pension benefit obligations have been declining since IBM froze the pension plan at the end of 2007.? If there is a severe downturn in the stock or bond market in the future, IBM may then have to make contributions to plan to bring it back up to fully funded status.? But for now, it is coasting along with the funds that are there.?
When IBM spun off Kyndryl, I don't believe any part of the pension plan went over to Kyndryl.? The employees who are now part of Kyndryl are now former employees of IBM, with vested rights to whatever pension benefits they had earned.? Some are eligible to retire under the IBM pension plan, and can start collecting their pension even though they are actively working for Kyndryl. Those who are not eligible to retire can start collecting their vested pension benefit.
IBM's pension obligations after the spin off of Kyndryl are the same as they were before the spin off.? Although IBM may have less revenue coming in without Kyndryl's revenue share, it doesn't seem likely that it will have any effect on the pension plan.
