Martin Marietta Won’t Match Rival LTV Offer: Martin Marietta Corp. said it will not increase its $440-million bid for the missile and aircraft divisions of LTV Corp. despite a new, higher offer from rival bidder Loral Corp. The Bethesda, Md.-based defense and aerospace contractor instead dismissed the Loral bid, which surpasses Martin Marietta’s by $35 million, and said it expects to close a deal with LTV within two weeks. A bankruptcy court judge could determine the fate of the LTV divisions at a hearing slated for today.
