next five year review of the liquids pipeline index to generate the index level to be effective july 1 , 2021 , thereby including the effect of the revised policy statement and the tax act in the determination of indexed rates prospectively , effective july 1 , 2021. the ferc 's establishment of a just and reasonable rate , including the determination of the appropriate liquids pipeline index , is based on many components , and tax related changes will affect two such components , the allowance for income taxes and the amount for accumulated deferred income taxes , while other pipeline costs also will continue to affect the ferc 's determination of the appropriate pipeline index . accordingly , depending on the ferc 's application of its indexing rate methodology for the next five year term of index rates , the revised policy statement and tax effects related to the tax act may impact our revenues associated with any transportation services we may provide pursuant to cost of service based rates in the future , including indexed rates . trends and outlook we continue to evaluate and execute strategies to enhance unitholder value through growth , as well as the integration and optimization of our diversified asset portfolio . we intend to target a minimum distribution coverage ratio of 1.50x , thereby promoting a prudent balance between distribution rate increases and enhanced financial flexibility and strength while maintaining our investment grade ratings . we anticipate significant earnings growth in 2019 from the completion of our project backlog . we also continue to seek asset optimization opportunities through strategic transactions among us and our subsidiaries and or affiliates , and we expect to continue to evaluate and execute on such opportunities . as we have in the past , we will evaluate growth projects and acquisitions as such opportunities may be identified in the future , and we believe that the current capital markets are conducive to funding such future projects . with respect to commodity prices , natural gas prices have remained comparatively low during most of the last twelve months as associated gas from shale oil resources has provided additional supply to the market , while united states consumption has been relatively flat . this supports natural gas export projects to mexico as well as lng exports . consequently , the gulf coast will likely be the fastest-growing demand market for united states natural gas . unlike natural gas , crude oil prices are influenced more by international markets than by domestic resources and technological advances . prices have rebounded significantly from 2016 lows , signaling united states crude and ngl production should continue to grow rapidly , particularly in the permian basin and bakken shale , while domestic consumption falls . energy exports from the united states are continuing to grow as a result , providing strong spreads from north dakota and west texas to the gulf coast . results of operations we report segment adjusted ebitda as a measure of segment performance . we define segment adjusted ebitda as earnings before interest , taxes ,

unrealized gains and losses on commodity risk management activities include unrealized gains and losses on commodity derivatives and inventory fair value adjustments ( excluding lower of cost or market adjustments ) . segment adjusted ebitda reflects amounts for unconsolidated affiliates based on the partnership 's proportionate ownership . adjusted ebitda is a non-gaap measure . although we

results replace_table_token_7_th see the detailed discussion of segment adjusted ebitda below . depreciation , depletion and amortization . depreciation , depletion and amortization expense increased
