摘要:
A special multi‐peril (SMP) insurance policy provides a water utility with comprehensive coverage in a wide variety of situations. The SMP package may offer crime protection coverage through fidelity bond, broad form money and securities, and depositors' forgery insurance. Miscellaneous SMP insurance commonly covers signs, water storage tanks, contractor and radio equipment, accounts receivable, and valuable papers. Other separate insurance programs discussed include workers' compensation, earthquake, flood, Directors and Officers, umbrella, and automobile insurance. The first part of this two‐part article appeared in the May 1982 issue of Opflow.
