You may be right, and GM's revenue remains massive so it's a fraction of revenue. The only area of concern is the growth presumptions in the pension fund. They are often around 7.5%, whereas real growth was 0.5%, putting a potential damper on the profit line (but I do not know that relative magnitude of that).
