In this video, Motley Fool industrials analyst Blake Bos gives investors a look at five companies with huge pension costs that make up large portions of their total liability. He discusses LSI (NASDAQ: LSI), U.S. Steel (X), Xerox (XRX), Caterpillar (CAT 0.86%), and Ford Motor (F 1.60%), and gives investors a feel for just how massive a burden these costs are to these companies. Blake also examines how much relief rising interest rates should provide to these companies in terms of pension burden and how much they stand to benefit as interest rates begin to come back up.
