(1) Management believes that an analysis of earnings before significant items, a quot;non-GAAP' measure is meaningful to
investors because it provides insight with respect to ongoing operating results of the company. Significant items
represent special charges or credits that are important to an understanding of the company's ongoing operations.
Such 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.
(2) See Reconciliation of Non-GAAP Measures
(3) EBIT is earnings before income taxes, corporate minority interests and interest expense.
EBITDA is EBIT before depreciation and amortization of intangible assets.
(4) Earnings per share for the year may not equal the sum of quarterly earning per share due to changes in average share
calculations.
