  Non-GAAP Financial Measures - EBITDA and Distributable Cash Flow

  The Partnership uses non-GAAP measures to evaluate its business and performance, including EBITDA and distributable cash flow. EBITDA is used as a supplemental financial measure by management and by external users

  of the Partnership's financial statements, such as investors, commercial banks, research analysts and rating agencies, to assess the Partnership's operating and financial performance, ability to generate cash and return on invested capital as compared to those of other companies in the midstream portion of the natural gas and natural gas liquids industry. Distributable cash flow is used as a supplemental financial measure by management and by external users of the Partnership's financial statements as an approximation of net operating revenues generated by the Partnership, that when realized in cash, will be available to be distributed to its unitholders and general partner.

  EBITDA and distributable cash flow should not be considered alternatives to net income, operating income, cash flow from operating activities or any other measure of financial performance or liquidity presented in accordance with generally accepted accounting principles (GAAP). EBITDA and distributable cash flow are not necessarily comparable to similarly titled measures of another company.

Brokers and nominees should treat 100% of Boardwalk's distributions to foreign investors as being attributable to income that is effectively connected with a United States trade or business.
