CDI Corp. (NYSE: CDI) announced Michael Castleman will take over as CFO following the filing of the company’s SEC Form 10-K earnings report for 2014 in early March. He assumed day-to-day responsibilities for financial operations and management and will continue to lead corporate development and operational analytics at CDI. Castleman will replace current CFO Robert Larney, who is leaving to pursue other opportunities.

Castleman is currently executive VP, corporate development and operations, and has led CDI’s enterprise analytics and performance optimization, as well as corporate development via partnerships, mergers and acquisitions.

He also has served as a director or board advisor to multiple companies.

Castleman is one of several former Sears execs to join CDI in 2014, including current CDI CEO Scott J. Friedman.

“Michael is an experienced financial and operating executive with the skills, integrity and commitment needed to build on CDI’s strengths and maximize long-term value,” said Freidheim.

CDI’s board last month approved a restructuring plan and the company expects to take a restructuring charge of between $3.2 million and $3.9 million in the fourth quarter.
