19 Appendix Financial Reconciliation Table (1) Free Cash Flow is defined as Operating Cash Flow less Purchases of Property, Plant and Equipment. Free cash flow is not defined by generally accepted accounting principles. However, we believe free cash flow to be relevant and useful information to our investors because it provides them with additional information in assessing our liquidity, capital resources and financial operating results. Our management uses free cash flow in evaluating our liquidity, our ability to service debt and our ability to fund capital additions. However, this measure should be considered in addition to, and not as a substitute for, or superior to, cash flows or other measures of financial performance prepared in accordance with generally accepted accounting principles, and our definition of free cash flow may not be comparable to similarly titled measures reported by other companies.
