Sea-Land rejected the Simmons takeover offer.

Acting on the advice of its financial adviser, Dillon, Read & Co., the board of directors of Sea-Land Corp. said the offer of $25 a share, or $585 million, from Dallas businessman Harold Simmons was “inadequate.” The board authorized management to explore all available alternatives. Meanwhile, Simmons, who already controls 25% of Sea-Land, will meet with management Tuesday. He has agreed not to buy any more Sea-Land stock before then.
