ethane demand is expected to ramp up as new world-scale ethylene production projects , petrochemical plant modifications , plant expansions and export facilities near completion and begin coming on line in 2017. we expect increases in future ethane recoveries to have a favorable impact on oneok partners ' financial results , beginning primarily in the second half of 2017. growth projects - oneok partners completed its bear creek natural gas processing plant and related infrastructure projects in august 2016. these projects expand oneok partners ' natural gas gathering and processing and natural gas liquids gathering infrastructure in the williston basin to capture natural gas from new wells and natural gas previously flared by producers . in the natural gas pipelines segment , phase i of the roadrunner pipeline was completed in march 2016. phase ii of the roadrunner pipeline and the westex pipeline expansion project were completed in october 2016 , ahead of original schedule and below cost estimates . the roadrunner pipeline transports natural gas from the permian basin in west texas to the mexican border near el paso , texas , and together with oneok partners ' westex intrastate natural gas transmission pipeline , creates a platform for future opportunities to deliver natural gas supply to mexico . the execution of these capital investments aligns with oneok partners ' strategy to generate consistent growth and sustainable earnings through long-term fee-based projects . oneok partners ' contractual commitments from crude oil and natural gas producers , natural gas processors and electric generators are expected to provide incremental cash flows and long-term fee-based earnings . change in presentation of financial results - our chief operating decision-maker reviews the financial performance of each of oneok partners ' three segments , as well as our financial performance , on a regular basis . beginning in 2016 , adjusted ebitda by segment is utilized in this evaluation . we believe this financial measure is useful to investors because it and similar measures are used by many companies in our industry as a measurement of financial performance and are commonly employed by financial analysts and others to evaluate our financial performance and to compare financial performance among companies in our industry . see reconciliation of net income to adjusted ebitda in the “ adjusted ebitda ” section . dividends/distributions - during 2016 , we paid dividends totaling $ 2.46 per share , which is an increase from the $ 2.43 per share paid in 2015 . we declared a quarterly dividend of $ 0.615 per share ( $ 2.46 per share on an annualized basis ) in january 2017 , which is unchanged from the quarterly dividend declared in january 2016 . oneok partners ' structure as a master limited partnership requires it to pay out all of its available cash , as defined in the partnership agreement , in distributions to its unitholders . during 2016 , oneok partners paid cash distributions of $ 3.16 per unit , which is unchanged from 2015. oneok partners paid total cash distributions to us in 2016 of $ 790.0 million , which includes $ 361.2 million from our limited-partner interest and $ 428.8 million from our general-partner interest , which includes our incentive distribution rights . oneok partners paid a cash distribution of $ 0.79 per unit ( $ 3.16 per unit on an annualized basis ) for the fourth quarter 2016 . 46 financial results and operating information consolidated operations selected financial results - the following table sets forth certain selected consolidated financial results for the periods indicated : replace_table_token_5_th * percentage change is greater than 100 percent or is not meaningful . see reconciliation of net income to adjusted ebitda in the “ adjusted ebitda ” section . due to the nature of oneok partners ' contracts , changes in commodity prices and sales volumes affect both commodity sales and cost of sales and fuel in our consolidated statements of income and therefore the impact is largely offset between the two line items . 2016 vs. 2015 - operating income increased due primarily to higher natural gas and ngl volumes from completed capital-growth projects in the natural gas gathering and processing and natural gas liquids segments and new plant connections and increased ethane recovery in the natural gas liquids segment , higher fees resulting from contract restructuring in the natural gas gathering and processing segment and higher firm demand charge volumes contracted in the natural gas pipelines segment . these increases were offset partially by lower net realized ngl and natural gas prices in the natural gas gathering and processing segment , higher depreciation expense due to projects completed in 2016 and 2015 , higher labor costs associated with the growth of operations in the natural gas gathering and processing segment and higher employee-related costs associated with incentive and medical benefit plans and noncash expenses of a share-based deferred compensation plan due primarily to the increase of oneok 's share price in 2016. equity in net earnings from investments increased due primarily to higher volumes delivered to overland pass pipeline from oneok partners ' bakken ngl pipeline and higher firm transportation revenues on northern border pipeline and roadrunner , offset partially by lower equity earnings from oneok partners ' powder river basin equity investments . interest expense increased primarily as a result of higher interest costs incurred associated with our $ 500 million debt issuance in august 2015 and lower capitalized interest due to lower spending on capital-growth projects . 47 net income attributable to noncontrolling interests , which reflects primarily the portion of oneok partners that we do not own , increased in 2016 , compared with 2015 , due primarily to higher earnings at oneok partners , including noncash impairment charges in 2015 discussed below . story_separator_special_tag 2015 vs. 2014 - adjusted ebitda increased $ 131.4 million , primarily as a result of the following : an increase of $ 288.1 million in exchange services , which includes : ◦ an increase of $ 191.0 million , which resulted from increased volumes from new plants connected in the williston basin and mid-continent region and higher revenues from customers with minimum volume obligations ; ◦ an increase of $ 75.0 million due primarily to the acquisition of the west texas lpg system in the permian basin , which was acquired in november 2014 ; and ◦ an increase of $ 23.8 million resulting from decreased ethane rejection in the williston basin resulting from downstream ngl product specification issues , offset partially by higher ethane rejection in the mid-continent region ; an increase of $ 11.4 million in equity in net earnings from investments due primarily to higher volumes delivered to overland pass pipeline from the bakken ngl pipeline ; and an increase of $ 6.8 million in transportation revenues due primarily to increased volumes on oneok partners ' distribution pipelines ; offset partially by a decrease of $ 118.4 million in optimization , marketing and differentials-based activities , which resulted from a $ 66.3 million decrease due primarily to narrower ngl product price differentials , a $ 27.7 million decrease due primarily to narrower ngl location price differentials and a $ 24.4 million decrease in the marketing business . a portion of this decrease relates to the increased demand for propane experienced during the first quarter 2014 ; a decrease of $ 29.9 million related to lower isomerization volumes resulting from narrower ngl price differential between normal butane and iso-butane ; an increase of $ 18.1 million in operating costs primarily as a result of the completion of growth projects and west texas lpg acquisition , which includes : ◦ an increase of $ 29.2 million due to the west texas lpg acquisition ; and ◦ an increase of $ 6.5 million due to higher ad valorem taxes ; offset partially by ◦ a decrease of $ 17.6 million due to reduced operating costs resulting from lower rates charged by service providers , primarily from $ 6.6 million lower outside services , $ 5.0 million lower supplies and expenses and $ 3.2 million lower chemicals and materials ; and a decrease of $ 6.9 million due to the impact of operational losses in 2015 and operational measurement gains in 2014. capital expenditures decreased due primarily to the completion of several growth projects in 2014 and spending reductions for growth capital to align with customer needs . in 2015 , oneok partners recorded a noncash impairment charge of $ 10.0 million related to a previously idled asset , as the expectation for future use of the asset changed . replace_table_token_11_th ( a ) - includes volumes for consolidated entities only . ( b ) - includes volumes at company-owned and third-party facilities . 2016 vs. 2015 - ngls transported on gathering lines remained relatively unchanged due to increased volumes from new plant connections in the williston basin , increased ethane recovery and increased mid-continent volumes gathered in the stack and scoop areas , offset by decreased volumes on the west texas lpg system , decreased mid-continent volumes gathered from the barnett shale , lower short-term contracted volumes and the impact of weather on gathered volumes across oneok partners ' system in december 2016. ngls fractionated increased due to increased volumes from new plant connections in the williston basin , increased ethane recovery and increased mid-continent volumes gathered in the stack and scoop areas , offset partially by decreased 53 volumes gathered from the barnett shale and lower short-term contracted volumes and the impact of weather on gathered volumes across oneok partners ' system in december 2016. while the volume of ethane recovered increased , a portion of the fees associated with those volumes gathered and fractionated was previously being earned under contracts with minimum volume obligations . ngls transported on distribution lines increased due primarily to higher gathered and fractionated volumes as discussed above and due to increased volumes transported for oneok partners ' optimization business . 2015 vs. 2014 - ngls transported on gathering lines and ngls fractionated increased due to increased volumes from new plant connections in the williston basin and mid-continent region and decreased ethane rejection in the rocky mountain region , offset partially by increased ethane rejection in the mid-continent region . the decreased ethane rejection in the rocky mountain region began in june 2015 due to downstream ngl product specifications and increased gathered volumes by approximately 20 mbbl/d in the second half of 2015. ngls transported on gathering lines also increased significantly due to volumes from the permian basin transported on the west texas lpg system , which was acquired in november 2014. ngls transported on distribution lines increased due primarily to higher gathered and fractionated volumes as discussed above and due to increased volumes transported for oneok partners ' optimi zation business . natural gas pipelines growth projects - roadrunner is a 50 percent-owned joint venture equity-method investment project . the westex pipeline expansion is a wholly owned project . oneok partners completed the following growth projects in this segment in 2016 : replace_table_token_12_th ( a ) - excludes capitalized interest .
