One of the longest-serving top executives at U.S. Steel (NYSE:X) will soon depart. The company announced that CFO Gretchen Haggerty has served notice that she is to enter retirement later this year, and that it has launched a "comprehensive search" to find a replacement.

Haggerty has been with the industrial giant since 1976, when she was hired to work in its tax division. She was elected vice president and treasurer in 1991, gradually moving up the ladder to executive vice president and CFO in early 2003.

She also serves as chairman of the United States Steel and Carnegie Pension Fund, and on that organization's investment committee. Outside of U.S. Steel, she sits on the board of directors of USG and the Pennsylvania Business Council, among other entities.
