APPENDIX

RECONCILIATION OF NON-GAAP MEASURES Page 12 The primary financial performance measures we use to manage our business and monitor results of operations are revenue trends and operating income trends. In addition, we consider adjusted operating income, adjusted operating margin, adjusted net income, and adjusted diluted earnings per share be useful to management and investors in evaluating our operating performance for the periods presented, and to provide a tool for evaluating our ongoing operations. This information can assist investors in assessing our financial performance and measures our ability to generate capital for deployment among competing strategic alternatives and initiatives. Adjusted operating income, adjusted operating margin, adjusted net income, and adjusted diluted earnings per share, however, are not measures of financial performance under generally accepted accounting principles in the United States of America (GAAP) and should not be considered a substitute for operating income, net income, diluted earnings per share, or net cash provided by operating activities as determined in accordance with GAAP. Reconciliations of these items are provided below. “Adjusted operating income” is defined as operating income, adjusted to exclude items that may include, but are not limited to, other income; significant charges or credits that impact current results but are not related to our ongoing operations and unusual and infrequent non-operating items and non-operating tax settlements or adjustments, such as separation costs incurred to become a stand-alone public company. “Adjusted operating margin” is defined as adjusted operating income divided by revenue. "Adjusted net income" is defined as net income, adjusted to exclude items that may include, but are not limited to, other income; significant charges or credits that impact current results that are related to our ongoing operations and unusual and infrequent non-operating items and non-operating tax settlements or adjustments, such as separation costs incurred to become a stand-alone public company. "Adjusted diluted earnings per share" is defined as adjusted net income divided by the weighted average diluted common shares outstanding.
