Deltic Timber appoints Byrom L. Walker as Interim CFO

Deltic Timber Corporation announced that Byrom L. Walker has been appointed Interim CFO, effective immediately. Mr. Walker’s appointment follows the decision by the Board of Directors to terminate Kenneth D. Mann as CFO. The Company has initiated a search process to identify a permanent CFO.

Mr. Walker has served as the Controller of Deltic since May, 2007. He has been with the Company for 11 years, having joined Deltic in 2006 as Manager of Financial Reporting. Prior to joining Deltic, Mr. Walker served as the Corporate Controller for Teris, LLC, a division of Suez S.A.

The termination of Mr. Mann was completed after the Board became aware that he misappropriated certain Company assets for personal use.

Deltic Timber Corporation is a vertically integrated natural resources company, which owns approximately 530,000 acres of timberland, operates two sawmills and a medium density fiberboard plant, and is engaged in real estate development.
