FedEx Corp. general counsel Christine Richards is retiring from her role, effective Sept. 30, according to an announcement from the company Thursday. Her successor has not yet been named.

Richards joined the FedEx legal department from private practice over three decades ago, in 1984. She served in a variety of leadership positions, including corporate vice president of customer and business transactions from March 2001 to June 2005. In June 2005, she assumed her current position as executive vice president, general counsel and secretary.

“Christine Richards has provided bold and innovative leadership in successfully addressing a wide variety of critical legal, regulatory and security challenges and opportunities for FedEx,” Frederick Smith, FedEx chairman and chief executive officer, said in the announcement. “Her untiring work ethic and in-depth knowledge of the inner workings of the business have made her service as a counselor and business partner invaluable.”
