Parker Total Orders for May Remain Constant Year over Year; International and Aerospace Gain Strength

Parker Hannifin Corporation reports that total orders for the month of May 2007 remained unchanged compared to orders in the same month a year ago. Orders are calculated as a percentage increase over the prior year using a daily average. The company derives orders from a wide variety of global end markets, which the company serves directly and through a network of thousands of distributor locations. In addition, Parker reported the following orders by operating segment:

• Orders decreased 10% in the Industrial North America segment versus May a year ago.
• Orders increased 13% in the Industrial International segment versus May a year ago.
• Orders increased 11% in the Aerospace segment on a rolling 12 month average basis.
• Orders decreased 15% in the Climate and Industrial Controls segment versus May a year ago.

Orders provide near-term perspective on the company's outlook, particularly when viewed in the context of prior and future monthly order rates. However, orders are not in themselves an indication of future performance. All comparisons are at constant currency exchange rates, with the prior year restated to the current-year rates. All exclude acquisitions until they can be reflected in both the numerator and denominator. Aerospace comparisons are rolling 12-month average computations. The Total Parker orders number is derived from a weighted average of the year-over-year monthly percent change in orders for the Industrial North America, Industrial International, and Climate and Industrial Controls segments, and the year-overyear 12-month rolling average of orders in the Aerospace segment. Comparisons are made using a daily average based on the number of workdays in the respective periods. A varying number of workdays year over year could influence the daily averages and could produce a different result than if the comparison was based on total order dollars for the periods.
