NON-GAAP RECONCILIATIONS

NON-GAAP FINANCIAL MEASURES Adjusted EBITDA and distributable cash flow are measures not defined by GAAP. Adjusted EBITDA is the primary measure used by our senior management, including our Chief Executive Officer, to: (i) evaluate our consolidated operating performance and the operating performance of our business segments; (ii) allocate resources and capital to business segments; (iii) evaluate the viability of proposed projects; and (iv) determine overall rates of return on alternative investment opportunities. We use distributable cash flow as a performance metric to compare cash generating performance of Buckeye from period to period and to compare the cash generating performance for specific periods to the cash distributions (if any) that are expected to be paid to our unit holders. Distributable cash flow is not intended to be a liquidity measure. Adjusted EBITDA and distributable cash flow eliminate: (i) non-cash expenses, including, but not limited to, depreciation and amortization expense resulting from the significant capital investments we make in our businesses and from intangible assets recognized in business combinations; (ii) charges for obligations expected to be settled with the issuance of equity instruments; and (iii) items that are not indicative of our core operating performance results and business outlook. Buckeye believes that investors benefit from having access to the same financial measures used by senior management and that these measures are useful to investors because they aid in comparing Buckeye’s operating performance with that of other companies with similar operations. The Adjusted EBITDA and distributable cash flow data presented by Buckeye may not be comparable to similarly titled measures at other companies because these items may be defined differently by other companies. This presentation references forward-looking estimates of Adjusted EBITDA investment multiples projected, to be generated by the investment in VTTI. A reconciliation of estimated Adjusted EBITDA to GAAP net income is not provided because GAAP net income generated by the investment for the applicable periods is not accessible. In addition, interest and debt expense is a corporate-level expense that is not allocated among Buckeye’s segments and could not be allocated to the operations of the partnership with VTTI without unreasonable effort. Accordingly, the amount of depreciation and amortization and interest and debt expense that will be included in the additional net income generated as a result of the acquisition of the 50 percent interest in the partnership with Vitol is not accessible or estimable at this time. The amount of such additional resulting depreciation and amortization and applicable interest and debt expense could be significant, such that the amount of additional net income would vary substantially from the amount of projected Adjusted EBITDA. © Copyright 2016 Buckeye Partners, L.P. 18
