Ingersoll-Rand Sues Over Partnerships: Ingersoll-Rand Financial Corp. filed suit in Superior Court claiming that a group of individuals and small real estate and financial companies in Southern California conspired against the New Jersey firm by setting up fraudulent limited partnerships. Ingersoll-Rand lent the partnerships money to fund small real estate development projects, but much of the money was siphoned to fees and commissions for the general partners, the suit said. Ingersoll claims that it lost more than $8 million.
