Definitions Financial Measures - US GAAP equivalents EBIT and EBIT Margin - EBIT, as used in this document, is equivalent to the US GAAP measure of operating income. EBIT margin is defined as EBIT as a percentage of net sales. We believe EBIT and EBIT margin to be relevant and useful information as these are the primary measures used by our management to measure the operating profit or loss of our business. EBIT is one of several metrics used by our management to measure the earnings generated from our operations, excluding interest and income tax expenses. Additionally, EBIT is believed to be a primary measure and terminology used by our Australian investors. EBIT and EBIT margin should be considered in addition to, but not as a substitute for, other measures of financial performance reported in accordance with accounting principles generally accepted in the United States of America. EBIT and EBIT margin, as we have defined them, may not be comparable to similarly titled measures reported by other companies. Operating profit - is equivalent to the US GAAP measure of income. Net operating profit - is equivalent to the US GAAP measure of net income. Sales Volumes mmsf - million square feet, where a square foot is defined as a standard square foot of 5/16" thickness. msf - thousand square feet, where a square foot is defined as a standard square foot of 5/16" thickness. Endnotes
