RECONCILIATION OF SELECTED CONTINUING OPERATIONS' GAAP MEASURES TO NON-GAAP MEASURES (In thousands, except per share data) (Unaudited) To supplement our condensed consolidated financial statements presented on a GAAP basis, Advent uses non-GAAP measures of continuing operations' operating income, net income and net income per share, which are adjusted to exclude certain costs, expenses, gains and losses we believe appropriate to enhance an overall understanding of our past financial performance and also our prospects for the future. These adjustments to our current period GAAP results are made with the intent of providing both management and investors a more complete understanding of Advent’s underlying operational results and trends and our marketplace performance. In addition, these adjusted non-GAAP results are among the information management uses as a basis for our planning and forecasting of future periods. The presentation of this additional information is not meant to be considered in isolation or as a substitute for results prepared in accordance with generally accepted accounting principles in the United States.
