He is quoted saying that right on the linked page. But here is the exact quote, in case you haven't perused the original submission:
"We had two AOL-ers that had distressed babies that were born that we paid a million dollars each to make sure those babies were OK in general. And those are the things that add up into our benefits cost. So when we had the final decision about what benefits to cut because of the increased healthcare costs, we made the decision, and I made the decision, to basically change the 401(k) plan."
Where exactly did he do that?
