Non-GAAP Measure:

The press release attached as Exhibit 99.1 contains a financial measure that is not defined under U.S. generally accepted accounting principles (“GAAP”).  The Company presented its Adjusted Earnings per Diluted Share financial measure to provide investors meaningful insight into the Company’s earnings performance without the impact of Business Support Center restructuring and other special charges (benefits), net, the gain on the sale of businesses, costs (benefits) related to Air Products’ unsolicited takeover attempt, multi-employer pension plan withdrawal charges, and income tax benefits related to the LLC reorganization and foreign tax liability true-up.

The Company’s intent is to provide non-GAAP financial information to enhance investors’ understanding of the Company’s consolidated financial statements and should be considered by the reader in conjunction with the financial statements prepared in accordance with GAAP, as non-GAAP financial information is merely a supplement to, and not a replacement for, GAAP financial information.  In addition, it should be noted that the Company’s non-GAAP financial information may be different from the non-GAAP financial information provided by other companies.
