Notes on Orders

Orders provide near-term perspective on the company’s outlook, particularly when viewed in the context of prior and future quarterly 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 quarterly percent change in orders for the Industrial North America, Industrial International, and Climate and Industrial Controls segments, and the year-over-year 12-month rolling average of orders for the Aerospace segment.

Forward-Looking Statements

Forward-looking statements contained in this and other written and oral reports are made based on known events and circumstances at the time of release, and as such, are subject in the future to unforeseen uncertainties and risks. All statements regarding future performance, earnings projections, events or developments are forward-looking statements. It is possible that the future performance and earnings projections of the company, including its individual segments, may differ materially from current expectations, depending on economic conditions within its mobile, industrial and aerospace markets, and the company’s ability to maintain and achieve anticipated benefits associated with announced realignment activities, strategic initiatives to improve operating margins, actions taken to combat the effects of the current economic environment, and growth, innovation and global diversification initiatives. A change in economic conditions in individual markets may have a particularly volatile effect on segment performance. Among other factors which may affect future performance are: changes in business relationships with and purchases by or from major customers, suppliers or distributors, including delays or cancellations in shipments, disputes regarding contract terms or significant changes in financial condition, changes in contract cost and revenue estimates for new development programs and changes in product mix; uncertainties surrounding timing, successful completion or integration of acquisitions; ability to realize anticipated costs savings from business realignment activities; threats associated with and efforts to combat terrorism; uncertainties surrounding the ultimate resolution of outstanding legal proceedings, including the outcome of any appeals; competitive market conditions and resulting effects on sales and pricing; increases in raw material costs that cannot be recovered in product pricing; the company’s ability to manage costs related to insurance and employee retirement and health care benefits; and global economic factors, including manufacturing activity, air travel trends, currency exchange rates, difficulties entering new markets and general economic conditions such as inflation, deflation, interest rates and credit availability.
