Hanson completed its Kaiser Cement tender.

Announcing the successful conclusion of its offer of $27.50 a share, Hanson Industries said it was notified that 5.6 million shares had been tendered, giving it a total of about 79% of Kaiser. Both Hanson and Kaiser said they did not know whether Los Angeles investor David Murdock had tendered Kaiser shares, previously reported as representing 22% of stock. Murdock could not be reached for comment. However, Hanson said holders of stock that was not tendered will be paid the same price when a Hanson subsidiary is merged into Kaiser.
