Reconciliation of Non-GAAP Measures Note: The Corporation has presented the following non-GAAP financial measures because it believes that these measures provide useful and comparative information to assess trends in the Corporation’s results of operations and financial condition. These non-GAAP financial measures are frequently used by securities analysts, investors and other interested parties in the evaluation of companies in the Corporation’s industry. Investors should recognize that the Corporation’s presentation of these non- GAAP financial measures might not be comparable to similarly-titled measures of other corporations. These non-GAAP financial measures should not be considered a substitute for GAAP basis measures, and the Corporation strongly encourages a review of its condensed consolidated financial statements in their entirety. 41
