WGP adopted Accounting Standards Update&#160;(&#8220;ASU&#8221;) 2014-09, </font><font style="font-family:inherit;font-size:10.5pt;font-style:italic;">Revenue from Contracts with Customers (Topic 606)</font><font style="font-family:inherit;font-size:10.5pt;"> (&#8220;Topic 606&#8221;), effective January 1, 2018. See </font><font style="font-family:inherit;font-size:10.5pt;font-style:italic;">Accounting standards adopted in 2018</font><font style="font-family:inherit;font-size:10.5pt;"> below for further discussion.</font></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10.5pt;"><font style="font-family:inherit;font-size:10.5pt;">Under its fee-based gathering, treating, processing and disposal arrangements, WES is paid a fixed fee based on the volume and/or thermal content of natural gas or produced water and recognizes revenues for its services in the month such services are performed. Producers&#8217; wells or production facilities are connected to WES&#8217;s gathering systems for delivery of natural gas to WES&#8217;s processing or treating plants, where the natural gas is processed to extract NGLs and condensate or treated in order to satisfy pipeline specifications. In some areas, where no processing is required, the producers&#8217; gas is gathered and delivered to pipelines for market delivery. Under cost-of-service gathering agreements, fees are earned for gathering and compression services based on rates calculated in a cost-of-service model and reviewed periodically over the life of the agreements. Under percent-of-proceeds contracts, revenue is recognized when the natural gas, NGLs or condensate is sold. The percentage of the product sale ultimately paid to the producer is recorded as a related cost of product expense.</font></div><div style="line-height:120%;text-align:justify;font-size:10.5pt;"><font style="font-family:inherit;font-size:10.5pt;"><br clear="none"/></font></div><div style="line-height:120%;font-size:10.5pt;"><font style="font-family:inherit;font-size:10.5pt;font-weight:bold;">1.&#160;&#160;SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)</font></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10.5pt;"><font style="font-family:inherit;font-size:10.5pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10.5pt;"><font style="font-family:inherit;font-size:10.5pt;">In certain circumstances, WES purchases natural gas volumes at the wellhead or production facility for gathering and processing. As a result, WES has volumes of NGLs and condensate to sell and volumes of residue to sell, to use for system fuel or to satisfy keep-whole obligations. In addition, depending upon specific contract terms, condensate and NGLs recovered during gathering and processing are either returned to the producer or retained and sold. Under keep-whole contracts, when condensate or NGLs are retained and sold, producers are kept whole for the condensate or NGL volumes through the receipt of a thermally equivalent volume of residue. The keep-whole contract conveys an economic benefit to WES when the combined value of the individual NGLs is greater in the form of liquids than as a component of the natural gas stream; however, WES is adversely impacted when the value of the NGLs is lower than the value of the natural gas stream including the liquids. WES has commodity price swap agreements with Anadarko to mitigate exposure to a majority of the commodity price risk inherent in its percent-of-proceeds and keep-whole contracts. See </font><font style="font-family:inherit;font-size:10.5pt;font-style:italic;">Note&#160;5</font><font style="font-family:inherit;font-size:10.5pt;">. Revenue is recognized from the sale of condensate and NGLs upon transfer of title, and related purchases are recorded as cost of product.</font></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10.5pt;"><font style="font-family:inherit;font-size:10.5pt;">WES earns transportation revenues through firm contracts that obligate each of its customers to pay a monthly reservation or demand charge regardless of the pipeline capacity used by that customer. An additional commodity usage fee is charged to the customer based on the actual volume of natural gas transported. Transportation revenues are also generated from interruptible contracts pursuant to which a fee is charged to the customer based on volumes transported through the pipeline. Revenues for transportation of natural gas and NGLs are recognized over the period of firm transportation contracts or, in the case of usage fees and interruptible contracts, when the volumes are received into the pipeline. From time to time, certain revenues may be subject to refund pending the outcome of rate matters before the Federal Energy Regulatory Commission, and refund reserve liabilities are established where appropriate.</font></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10.5pt;"><font style="font-family:inherit;font-size:10.5pt;">Revenues attributable to the fixed-fee component of gathering and processing contracts as well as demand charges and commodity usage fees on transportation contracts are reported as revenues from gathering, processing, transportation and disposal in the consolidated statements of operations. Proceeds from the sale of residue, NGLs and condensate are reported as revenues from natural gas and natural gas liquids sales in the consolidated statements of operations.</font></div></div>
