Safe harbor comments 2 Non-GAAP Financial Measures The Company uses certain non-GAAP financial measures, which are measures of its historical or future financial performance that are not calculated and presented in accordance with GAAP, within the meaning of applicable SEC rules. Management believes that its presentation and use of certain non-GAAP financial measures, including adjusted earnings, adjusted earnings per share, segment operating profit, segment operating profit margin and adjusted free cash flow, provide relevant and useful supplemental financial information, which is widely used by analysts and investors, as well as by management in assessing both consolidated and business unit performance. These non-GAAP measures are reconciled to the most directly comparable GAAP measures and should be considered supplemental in nature and should not be considered in isolation or be construed as being more important than comparable GAAP measures. Adjusted earnings relates to net earnings from continuing operations attributable to the Company, exclusive of items management considers not representative of ongoing operations because such items are not reflective of the Company’s principal business activity, which is glass container production. Adjusted earnings are divided by weighted average shares outstanding (diluted) to derive adjusted earnings per share. Segment operating profit relates to earnings from continuing operations before interest expense (net), provision for income taxes and is also exclusive of items management considers not representative of ongoing operations. Segment operating profit margin is segment operating profit divided by segment net sales. Management uses adjusted earnings, adjusted earnings per share, segment operating profit and segment operating profit margin to evaluate its period-over-period operating performance because it believes this provides a useful supplemental measure of the results of operations of its principal business activity by excluding items that are not reflective of such operations. Adjusted earnings, adjusted earnings per share, segment operating profit and segment operating profit margin may be useful to investors in evaluating the underlying operating performance of the Company’s business as these measures eliminate items that are not reflective of its principal business activity. Further, adjusted free cash flow relates to cash provided by continuing operating activities less additions to property, plant and equipment plus asbestos-related payments. Management uses adjusted free cash flow to evaluate its period-over-period cash generation performance because it believes this provides a useful supplemental measure related to its principal business activity. Adjusted free cash flow may be useful to investors to assist in understanding the comparability of cash flows generated by the Company’s principle business activity. Since a significant majority of the Company’s asbestos-related claims are expected to be received in the next ten years, adjusted free cash flow may help investors to evaluate the long-term cash generation ability of the Company’s principal business activity as these asbestos-related payments decline. It should not be inferred that the entire adjusted free cash flow amount is available for discretionary expenditures, since the Company has mandatory debt service requirements and other non-discretionary expenditures that are not deducted from the measure. Management uses non-GAAP information principally for internal reporting, forecasting, budgeting and calculating compensation payments.

It is not possible to foresee or identify all such factors. Any forward-looking statements in this document are based on certain assumptions and analyses made by the Company in light of its experience and perception of historical trends, current conditions, expected future developments, and other factors it believes are appropriate in the circumstances.

Continued favorable trends in asbestos 12 1 year ASBESTOS PAYMENTS TOTAL EXPECTED ASBESTOS-RELATED LIABILITY1 1 The Company’s ultimate asbestos-related liability cannot be estimated with certainty. As part of its future comprehensive annual reviews, the Company will estimate its total asbestos-related liability and such reviews may result in adjustments to the liability accrued at the time of the review. The 2017 forecasted asbestos-related liability is calculated as the Dec. 31, 2016 asbestos-related liability less the forecasted 2017 asbestos payments and does not include an adjustment for asbestos-related costs at this time. Annual comprehensive legal review yielded no change to liability in 2016; 2017 review is on-going Expecting ~$10-15M reduction in annual asbestos payments Payments in 2016 were 40% lower than 2008 Average age of claimant is >80 years old and continues to increase each year
