Research and development cost declines are due primarily to shifting investment to food renovation. We use this non-GAAP financial measure, which is reconciled above, to focus management and investors on the amount of cash available for debt repayment, dividend distribution, acquisition opportunities, and share repurchase. Interest coverage ratio is calculated based on net income attributable to Kellogg Company before interest expense, income taxes, depreciation and amortization, divided by interest expense. 25
