(The Other segment includes the results of the heat exchanger manufacturing
operation and used equipment sales.)
During the second quarter of fiscal 1995, Energy Industries disposed of its
heat exchanger manufacturing operation for $1.5 million, resulting in a gain of
$452,000. The heat exchanger operation was not material to the operating results
or financial position of the Company.
Natural gas compressor package rental utilization is affected primarily by
the number and age of producing oil and gas wells, the volume of natural gas
consumed and natural gas prices. Rental rates are determined primarily by the
demand for compressor packages and vary by size and horsepower of a compressor
package. Energy Industries' utilization, rental rates and fleet size as of March
31, 1995 and 1994 are compared in the following table.
