Litton Industries Quarterly Profit Tops $28 Million: The company reported earnings of $28.6 million, or 60 cents a share, for its fiscal second quarter, citing lower interest costs and higher margins during the period. The results contrast with a loss of $151.3 million, or $3.32 a share, a year earlier, due primarily to costs associated with spinning off non-defense businesses into a separate company. Woodland Hills-based Litton builds electronics systems, defense systems and warships.
