A longtime director on the McDonald's Corp. (MCD) board is stepping down.

Jeanne Jackson, who has served on the board of the Chicago-based restaurant chain since 1999, has decided not to stand for reelection at the company's annual shareholder meeting, McDonald's said in a securities filing.

The only member of the McDonald's board who has served longer than Ms. Jackson is Enrique Hernandez Jr., its chairman, according to the company's proxy statement for 2018. He joined the board in 1996.

Ms. Jackson previously worked for Nike Inc. and Walmart Inc., according to last year's proxy statement.
