Calculation of Adjusted EBITDA & Leverage Ratio 31 Last 4 fiscal quarters (September 25, 2016 to September 30, 2017) Certain of our debt agreements contain covenants that require us to maintain certain coverage ratios. Our Debt/Adjusted EBITDA may not exceed 3.5X Adjusted EBITDA of the prior four quarters. See “Leverage Ratio “ below.

32 Calculation of Return on Invested Capital Return on Invested Capital (“ROIC”) is calculated as Operating Income (after-tax) divided by the average of beginning and ending Invested Capital. Invested Capital represents total assets minus total liabilities (excluding interest-bearing debt). Return on Invested Capital is one of our key operating ratios, as it allows investors to analyze our operating performance in light of the amount of investment required to generate our operating profit. Return on Invested Capital is also a measurement used to determine management incentives. Return on Invested Capital is a non-GAAP measure. Accordingly, Invested Capital and Return on Invested Capital should not be considered in isolation or as a substitute for net earnings, cash flows from operations or other income or cash flow data prepared in accordance with GAAP or as a measure of our operating performance or liquidity. The table below shows how Invested Capital and Return on Invested Capital are calculated from our income statement and balance sheet. Return on Invested Capital, as presented, may not be comparable to similarly titled measures of other companies.” 1. The adjusted effective tax rate in 2016 excludes deferred income tax benefit of $30,590 resulting primarily from the re-measurement of the deferred tax asset for the Company's U.K. defined benefit pension plan. In addition, fiscal 2016 excludes $9,888 recorded as a valuation allowance against a tax credit asset. Finally, it excludes the reversal of a contingent liability that was recognized as part of the Delta purchase accounting of $16,591, which is not taxable.
