Kaiser Aluminum commented on a 13D filing.

The Securities and Exchange filing disclosed that a group that includes Oklahoma investor J. A. Frates and British investor Alan E. Clore will seek control of the Oakland-based company. “We don’t intend to permit Mr. Frates or Mr. Clore to . . . grab Kaiser Aluminum & Chemical Corp.’s considerable values for their own personal benefit,” the Oakland-based company said in a statement.
