“LIKE millions of retirees who assumed their companies had taken care of them, Ronald Tussey never thought that his retirement plan might be flawed. He trusted his company so much he kept his money in his 401(k) long after he left.

Having worked as an engineer for 37 years, ultimately at ABB Inc., where he retired 11 years ago, Mr. Tussey said he never paid much attention to the fees in his retirement plan and “assumed the company was looking out for my best interests.”

But after seeing a television program on the negative impact that 401(k) expenses can have on retirement savings, he hired a lawyer, who filed a class-action lawsuit in 2006 against ABB and plan administrators.”
