Non-GAAP measures: This presentation includes certain non-GAAP financial measures. These financial measures have been included as they provide meaningful supplemental information to assess trends in the Corporation’s results of operations. These non- GAAP measures are provided in addition to, and not as substitutes for, measures of our financial performance determined in accordance with GAAP.
