Holly Energy Partners, L.P. (HEP) BPD: Barrels per day EBITDA: Earnings before interest, taxes, depreciation and amortization which is calculated as net income plus (i) interest expense net of interest income and (ii) depreciation and amortization. EBITDA is not a calculation based upon U.S. generally accepted accounting principles ("U.S. GAAP"). However, the amounts included in the EBITDA calculation are derived from amounts included in our consolidated financial statements. EBITDA should not be considered as an alternative to net income or operating income, as an indication of our operating performance or as an alternative to operating cash flow as a measure of liquidity. EBITDA is not necessarily comparable to similarly titled measures of other companies. EBITDA is presented here because it is a widely used financial indicator used by investors and analysts to measure performance. EBITDA is also used by our management for internal analysis and as a basis for compliance with financial covenants. STEADY STATE EBITDA: EBITDA as defined above calculated on the basis of our projection of normal pipeline and terminal volumes from our customers, applicable tariffs and fees, and normal expense levels, and assuming no material unplanned shutdowns or unavailable capacity.
