Use of Non-GAAP Financial InformationThe Partnership reports its financial results in accordance with United States generally accepted accounting principles (GAAP). However, from time to time, the Partnership uses certain non-GAAP financial measures such as distributable cash flow because the Partnership's management believes that this measure may provide users of this financial information with meaningful comparisons between current results and prior reported results and a meaningful measure of the Partnership's cash available to pay distributions. Distributable cash flow should not be considered an alternative to cash flow from operating activities or any other measure of financial performance in accordance with GAAP. Distributable cash flow is not intended to represent cash flows for the period, nor is it presented as an alternative to income from continuing operations. Furthermore, it should not be seen as a measure of liquidity or a substitute for comparable metrics prepared in accordance with GAAP. This information may constitute non-GAAP financial measures within the meaning of Regulation G adopted by the SEC. Accordingly, the Partnership has presented herein, and will present in other information it publishes that contains this non-GAAP financial measure, a reconciliation of this measure to the most directly comparable GAAP financial measure. The Partnership has included below a table entitled "Distributable Cash Flow" in order to show the components of this non-GAAP financial measure and its reconciliation to the most comparable GAAP measure. The Partnership calculates distributable cash flow as follows: net income (as reported in statements of operations), plus depreciation and amortization, amortization of debt discount, and amortization of deferred debt issue costs (as reported in statements of cash flows), plus (less) deferred income taxes (as reported in statements of cash flows), plus costs related to the early extinguishment of interest rate swaps (as reported under the caption "Long-Term Debt and Capital Leases" in the Partnership's Annual Report on Form 10-K filed with the SEC on March 2, 2011), plus distribution equivalents from unconsolidated entities (as described below), plus (less) invested cash in unconsolidated entities (as described below), less equity in earnings of unconsolidated entities (as reported in statements of operations), plus non-cash mark-to-market on derivatives (as reported in statements of cash flows), less maintenance capital expenditures (as reported under the caption "Liquidity and Capital Resources" in the Partnership's Annual Report on Form 10-K filed with the SEC on March 2, 2011), plus (less) gain/(loss) on disposition or sale of property, plant and equipment (as reported in statements of cash flows), less payments for plant turn around costs (as reported in statements of cash flows), plus unit-based compensation (as reported in statements of changes in capital).
