natural gas throughput midstream holdings must continually obtain additional supplies of natural gas to maintain or increase throughput on its systems . midstream holdings ' ability to maintain existing supplies of natural gas and obtain additional supplies is primarily impacted by its acreage dedication and the level of successful drilling activity by devon and , to a lesser extent , the acreage dedications with and successful drilling by other producers . items affecting comparability of midstream holdings ' financial results the historical financial results of the predecessor discussed below may not be comparable to midstream holdings ' future financial results for the following reasons : · the predecessor 's historical assets comprised all of devon 's u.s. midstream assets and operations . however , only its assets serving the barnett , cana-woodford and arkoma-woodford shales , as well as the 38.75 % economic interest in gulf coast fractionators , were contributed to midstream holdings in connection with the consummation of the merger . these assets generated approximately 96 % of the predecessor 's net income from continuing operations for year ended december 31 , 2013 . · midstream holdings has entered into new agreements with devon pursuant to which midstream holdings provides services under fixed-fee arrangements and no longer takes title to the natural gas gathered and processed or the ngls it fractionates . · the predecessor 's historical combined financial statements include u.s. federal and state income tax expense . due to midstream holdings ' status as a partnership , the 50 % interest in midstream holdings that is owned directly by the partnership will not be subject to u.s. federal income tax and certain state income taxes in the future . · all historical affiliated transactions related to midstream holdings ' continuing operations were net settled within its combined financial statements because these transactions related to devon and were funded by devon 's working capital . in the future , all of midstream holdings ' transactions will be funded by its working capital . this will impact the comparability of its cash flow statements , working capital analysis and liquidity discussion . general trends and outlook natural gas and ngl supply and demand midstream holdings ' gathering and processing operations are generally dependent upon natural gas production from devon 's upstream activity in its areas of operation . the significant decline in natural gas prices as a result of significant new supplies of domestic natural gas production has caused a related decrease in dry natural gas drilling by many producers in the united states . depressed oil and natural gas prices could affect production rates over time and levels of investment by devon and third parties in exploration for and development of new oil and natural gas reserves . in addition , there is a natural decline in production from existing wells that are connected to midstream holdings ' gathering systems . midstream holdings believes devon 's five-year minimum volume commitments substantially reduce midstream holdings ' volumetric risk over that period of time . after the expiration of these five-year minimum volume commitments , a material decline in the volume of natural gas that midstream holdings gathers and transports on its systems would result in a material decline in its total operating revenues and cash flows . although midstream holdings expects that devon will continue to devote substantial resources to the development of the barnett and cana-woodford shales , it has no control over this activity and devon has the ability to reduce or curtail such development at its discretion . rising operating costs and inflation the current level of exploration , development and production activities across the united states has resulted in increased competition for personnel and equipment . this competition has caused , and midstream holdings believes it will continue to cause , increases in the prices it pays for labor , supplies and property , plant and equipment . an increase in the general level of prices in the economy could have a similar effect on the operating costs midstream holdings incurs . midstream holdings will 45 attempt to recover increased costs from its customers , but there may be a delay in doing so or it may be unable to recover all these costs . to the extent midstream holdings is unable to procure necessary supplies or recover higher costs , its operating results will be negatively impacted . regulatory compliance the regulation of natural gas gathering and transportation activities by ferc and other federal and state regulatory agencies , including the dot , has a significant impact on midstream holdings ' business . for example , phmsa has established pipeline integrity management programs that require more frequent inspections of pipeline facilities and other preventative measures , which may increase midstream holdings ' compliance costs and increase the time it takes to obtain required permits . additionally , increased regulation of oil and natural gas producers , including regulation associated with hydraulic fracturing , could reduce regional supply of oil and natural gas and therefore throughput on midstream holdings ' gathering systems . results of predecessor 's operations the following schedule presents the predecessor 's historical combined key operating and financial metrics . replace_table_token_7_th since 2011 , operating margin has consistently improved as a result of production growth . the largest contributors to rising production have been midstream holdings ' cana , bridgeport rich , and acacia systems , with daily throughput growth of 83 % , 6 % , and 6 % , respectively , from 2011 to 2013. this growth is the result of devon and other producers developing liquids-rich natural gas production in the cana-woodford and barnett shales . however , overall growth has been limited by throughput declines for the predecessor 's other systems , which are the result of natural gas price decreases . story_separator_special_tag this formula uses an equal weighting of revenues , employee compensation and gross property , plant and equipment balances to determine amounts to be allocated to midstream holdings and other devon affiliates . these cost allocations are affected by the amount of costs devon incurs for its centralized overhead and operating activities and the allocation methodologies chosen . determining the amount of costs devon incurs for its centralized overhead and operating activities generally does not require significant judgment by management because such costs are readily identifiable . although there are a number of alternative methodologies for allocating devon 's centralized overhead and operating costs , management believes the allocation methodologies used are based on assumptions that are reasonable . however , if certain costs were allocated using different methodologies , midstream holdings ' profitability and financial condition could change significantly . depreciation of property , plant and equipment midstream holdings ' depreciation calculations include estimates of salvage value and useful lives . as estimates of salvage values decrease , the amount of depreciation recognized in successive periods and over the estimated useful life of pp & e increases . midstream holdings estimates salvage values to be near zero at the end of the asset 's useful life . similar to salvage value estimates , as estimates of useful lives decrease , the amount of depreciation recognized in successive periods increases . however , useful life estimates have no impact on the amount of depreciation recognized over the life of pp & e . for assets subject to the straight-line method of calculating depreciation , midstream holdings utilizes estimated useful lives ranging from three to 25 years . these estimates are based on the historical usage of similar assets . for assets subject to the units-of-production basis of calculating depreciation , useful lives are estimated based on proved oil , natural gas and ngl reserve estimates from the fields being serviced by those assets . estimates of reserves are forecasts based on engineering data , projected future rates of production and the timing of future expenditures . the process of estimating oil , natural gas and ngl reserves requires substantial judgment , resulting in imprecise determinations , particularly for new discoveries . different reserve engineers may make different estimates of reserve quantities based on the same data . however , based on historical experience , such differences are not expected to be material . 49 impairment of property , plant & equipment midstream holdings evaluates property , plant & equipment ( pp & e ) for potential impairment annually and more frequently when events or changes in circumstances indicate that the carrying amount of midstream holdings ' pp & e may not be recoverable from estimated future cash flows . midstream holdings determines pp & e fair values from estimated discounted future net cash flows . the estimated cash flows can be significantly affected by the inputs used in the calculations , such as future throughput volumes , natural gas and ngl prices , operating costs , useful lives and discount rates . different assumptions and judgments could be used to determine the cash flow inputs . there are also alternative valuation techniques that could be used to estimate fair value . there are a number of inter-related inputs that can affect discounted cash flows . due to the number of inter-related inputs , it is impractical to provide specific quantitative analyses of potential changes in these estimates . however , general analyses can be provided for the most significant inputs which include current and projected throughput and current and projected natural gas and ngl prices . as such inputs decrease , the cash flows will generally change in a like manner and would increase the likelihood of a pp & e impairment charge . a pp & e impairment would have no direct effect on midstream holdings ' operating margin or liquidity . however , it would adversely affect midstream holdings ' net income . goodwill valuation midstream holdings has one reporting unit with goodwill , which requires management to estimate the fair value of the reporting unit and evaluate goodwill for potential impairment . midstream holdings tests goodwill annually in the fourth quarter of each year and more frequently when an event occurs or circumstances change that would more likely than not reduce the fair value of midstream holdings ' reporting unit below its carrying amount . because quoted market prices are not available for midstream holdings ' reporting unit , midstream holdings estimates its fair value using valuation analyses based on values of comparable companies and comparable transactions . in a comparable companies analysis , midstream holdings reviews the public stock market trading multiples for selected publicly-traded midstream companies with comparable financial and operating characteristics . these characteristics are market capitalization , location of midstream operations and the characterization of such operations that are deemed to be similar to ours . in a comparable transactions analysis , midstream holdings reviews certain acquisition multiples for selected recent midstream company or asset package transactions . the fair value of midstream holdings ' reporting unit is then estimated by applying the average multiple determined from the two valuation techniques described above to current year projected cash flow . as these valuation multiples decrease , the estimated fair value of the reporting unit would decrease . as a result , the likelihood of a goodwill impairment charge would increase . there are a number of inter-related inputs which can affect the valuation multiples . due to the number of inter-related inputs , it is impractical to provide specific quantitative analyses of potential changes in these estimates . however , general analyses can be provided for the most significant inputs which include current and projected throughput and current and projected natural gas and ngl prices . as such inputs decrease , the trading multiples will generally change in a like manner and would increase the likelihood of a goodwill impairment charge . a
