The closing follows the receipt of all necessary regulatory and other approvals, including the approval of Umeco stockholders.

Use of Non-GAAP Measures

Management believes that earnings per share before special items, which is a non-GAAP measurement, is meaningful to investors because it provides a view of the Company with respect to

ongoing operating results. Special items represent significant charges or credits that are important to an understanding of the Company’s overall operating results in the period presented. Such non-GAAP measurements are not recognized in accordance with generally accepted accounting principles (GAAP) and should not be viewed as an alternative to GAAP measures of performance.
