These measures may differ from similarly captioned measures of other companies in our industry.  Non-GAAP Measures  Our definitions of Credit Agreement EBITDA and Segment EBITDA may differ from other similarly titled measures at other companies. Credit Agreement EBITDA (as defined) and Adjusted EBITDA (as defined) are not defined in accordance with GAAP and should not be viewed as alternatives to GAAP measures of operating results or liquidity. RockTenn management believes that net income is the most directly comparable GAAP measure to Credit Agreement EBITDA (as defined) and Segment Income is the most directly comparable GAAP measure to Segment EBITDA.   Other Placeholder: 18   19 Title:  Non-GAAP Measures: Credit Agreement EBITDA and Total Funded Debt (as defined)  Other Placeholder: “Credit Agreement EBITDA” is calculated in accordance with the definition of “EBITDA” contained in the Company’s Credit Agreement. Credit Agreement EBITDA is generally defined as Consolidated Net Income plus: consolidated interest expense; consolidated tax expenses; depreciation and amortization expenses; charges and expenses for financing fees and expenses and write-offs of deferred financing fees and expenses, remaining portions of OID on prepayment of indebtedness, premiums due in respect of prepayment of indebtedness, and commitment fees in respect of financing commitments; various charges and expenses related to, or incurred in connection with, the Smurfit-Stone acquisition; costs and expenses relating to the integration of Smurfit-Stone and the achievement of synergies relating to the Smurfit-Stone acquisition; certain run-rate synergies expected to be achieved due to the Smurfit-Stone acquisition; all non-cash charges; all cash charges and expenses for plant and other facility closures and other cash restructuring charges; labor disruption charges; officer payments associated with any permitted acquisitions; “black liquor” expenses; cash charges and expenses incurred in respect of the Chapter 11 bankruptcy proceeding and plan of reorganization of Smurfit-Stone; and all non-recurring cash expenses taken in respect of any multi-employer and defined benefit pension plan obligations that are related to plant and other facilities closures.  For additional information on the calculation see our Credit Agreement, dated as of September 27, 2012, filed as Exhibit 10.1 to our Form 8-K, dated September 27, 2012.  “Total Funded Debt” is calculated in accordance with the definition of “Total Funded Debt” contained in the Company’s Credit Agreement.  Total Funded Debt is generally defined as aggregate debt obligations reflected in our balance sheet, less the hedge adjustments resulting from terminated and existing fair value interest rate derivatives or swaps, plus additional outstanding letters of credit not already reflected in debt, plus debt guarantees.     Other Placeholder: 19   20 Title:  Non-GAAP Measures: Credit Agreement EBITDA and Total Funded Debt  Other Placeholder: Our management uses Credit Agreement EBITDA and Total Funded Debt to evaluate compliance with RockTenn’s debt covenants and borrowing capacity available under its Credit Agreement.  Management also uses Credit Agreement EBITDA as a measure of our Company’s core operating performance.  Management believes that investors also use these measures to evaluate the Company’s compliance with its debt covenants and available borrowing capacity. Management also believes that investors use Credit Agreement EBITDA as a measure of our Company’s core operating performance. Borrowing capacity is dependent upon, in addition to other measures, the “Total Funded Debt/EBITDA ratio” or the “Leverage Ratio,” which is defined as Total Funded Debt divided by Credit Agreement EBITDA.   Other Placeholder: 20   21 Title: Non-GAAP Measures:  Net Debt  Other Placeholder: We have defined the non-GAAP measure “Net Debt” to include the aggregate debt obligations reflected in our balance sheet, less the hedge adjustments resulting from terminated and existing fair value interest rate derivatives or swaps, the balance of our cash and cash equivalents, restricted cash (which includes the balance sheet line items restricted cash and restricted cash and marketable debt securities) and certain other investments that we consider to be readily available to satisfy such debt obligations.  Our management uses Net Debt, along with other factors, to evaluate our financial condition.  We believe that Net Debt is an appropriate supplemental measure of financial condition and may be useful to investors because it provides a more complete understanding of our financial condition before the impact of our decisions regarding the appropriate use of cash and liquid investments.    Other Placeholder: 21   22 Title: Non-GAAP Measures:  Adjusted Net Income  and  Adjusted Earnings Per Diluted Share Other Placeholder: We also use the non-GAAP measures “adjusted net income” and “adjusted earnings per diluted share”.  Management believes these non-GAAP financial measures provide our board of directors, investors, potential investors, securities analysts and others with useful information to evaluate the performance of the Company because it excludes restructuring and other costs, net, the alternative fuel mixture credit and cellulosic biofuel producer credit and other specific items that management believes are not indicative of the ongoing operating results of the business.  The Company and the board of directors use this information to evaluate the Company’s performance relative to other periods.  Other Placeholder: 22   23 Title: Segment EBITDA Margins Other Placeholder: 23  1Q’13  ($ Millions, except percentages)  23   24 Title: Segment EBITDA Margins Other Placeholder: 24  1Q’12  ($ Millions, except percentages)  24  (1) Corrugated Packaging segment excludes $0.4 million of inventory step-up expense    25 Title: Segment EBITDA Margins Other Placeholder: 25  4Q’12  ($ Millions, except percentages)  (1) Corrugated Packaging segment excludes $0.2 million of inventory step-up expense   25   26 Title: Adjusted EPS Reconciliation Other Placeholder: 26  (1) Restructuring and other costs and operating losses and transition costs due to plant closures.   27 Title: Net Debt Reconciliation Other Placeholder: 27   28 Title: Credit Agreement EBITDA and Leverage Ratio Other Placeholder: 28  (1) As specified in our Credit Agreement dated September 27, 2012   29 Title: Credit Agreement EBITDA Breakout of Additional Permitted Charges Other Placeholder: 29  29  (1) As specified in our Credit Agreement dated September 27, 2012   30 Title: Credit Agreement EBITDA and Margin  Other Placeholder: 30  (1) As specified in our Credit Agreement dated September 27, 2012.   31  Executing Our Strategy, Delivering Exceptional Value
