While in bankruptcy, SemGroup, L.P. filed a plan of reorganization with the court, which was confirmed on October 28, 2009 (the &amp;#8220;Plan of Reorganization&amp;#8221;). The Plan of Reorganization determined, among other things, how pre-Petition Date obligations would be settled, the equity structure of the reorganized company upon emergence, and the financing arrangements upon emergence. SemGroup Corporation, SemCrude, and Eaglwing emerged from bankruptcy protection on November 30, 2009 (the &amp;#8220;Emergence Date&amp;#8221;). &lt;/font&gt;&lt;/div&gt;&lt;table cellpadding="0" cellspacing="0" style="padding-top:6px;font-family:Times New Roman; font-size:10pt;"&gt;&lt;tr&gt;&lt;td style="width:84px;" rowspan="1" colspan="1"&gt;&lt;/td&gt;&lt;td rowspan="1" colspan="1"&gt;&lt;/td&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td style="vertical-align:top" rowspan="1" colspan="1"&gt;&lt;div style="line-height:120%;font-size:10pt;padding-left:36px;"&gt;&lt;font style="font-family:inherit;font-size:10pt;font-style:italic;"&gt;(a) &lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;td style="vertical-align:top;" rowspan="1" colspan="1"&gt;&lt;div style="line-height:120%;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;font-style:italic;"&gt;Confirmation order appeal&lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;div style="line-height:120%;padding-top:6px;padding-left:84px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;font-style:italic;"&gt;Luke Oil appeal.&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt; On October&amp;#160;21, 2009, Luke Oil Company, C&amp;amp;S Oil/Cross Properties, Inc., Wayne Thomas Oil and Gas and William R. Earnhardt Company (collectively, &amp;#8220;Luke Oil&amp;#8221;) filed an objection to the Plan of Reorganization &amp;#8220;to the extent that the Plan of Reorganization may alter, impair, or otherwise adversely affect Luke Oil&amp;#8217;s legal rights or other interests.&amp;#8221; On October&amp;#160;28, 2009, the bankruptcy court overruled the Luke Oil objection and entered the confirmation order.&amp;#160;On November&amp;#160;6, 2009, Luke Oil filed a Notice of Appeal. On December&amp;#160;23, 2009, Luke Oil&amp;#8217;s appeal was docketed in the United States District Court for the District of Delaware. We filed a motion to dismiss the appeal as equitably moot.  On May 21, 2012, the District Court entered an order granting our motion to dismiss Luke Oil's appeal of the confirmation order. On June 18, 2012, Luke Oil filed its Notice of Appeal, notifying the District Court and the parties to the lawsuit that it was appealing the decision of the District Court to the United States Court of Appeals for the Third Circuit. The appeal has been fully briefed. The Court of Appeals heard oral argument on January 22, 2013, and has not yet ruled. While we believe that this action is without merit and are vigorously defending this matter on appeal, an adverse ruling on this action could have a material adverse impact on us.&lt;/font&gt;&lt;/div&gt;&lt;table cellpadding="0" cellspacing="0" style="padding-top:12px;font-family:Times New Roman; font-size:10pt;"&gt;&lt;tr&gt;&lt;td style="width:84px;" rowspan="1" colspan="1"&gt;&lt;/td&gt;&lt;td rowspan="1" colspan="1"&gt;&lt;/td&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td style="vertical-align:top" rowspan="1" colspan="1"&gt;&lt;div style="line-height:120%;font-size:10pt;padding-left:36px;"&gt;&lt;font style="font-family:inherit;font-size:10pt;font-style:italic;"&gt;(b) &lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;td style="vertical-align:top;" rowspan="1" colspan="1"&gt;&lt;div style="line-height:120%;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;font-style:italic;"&gt;Investigations&lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;div style="line-height:120%;padding-top:6px;padding-left:84px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;Around the time of our predecessor's bankruptcy filings, several governmental agencies launched investigations regarding the circumstances of the filings. The mandate and scope of these investigations were very broad and the investigations are ongoing.&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:6px;padding-left:84px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;font-style:italic;"&gt;Bankruptcy examiner.&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt; On October&amp;#160;14, 2008, the bankruptcy court appointed an examiner to (i)&amp;#160;investigate the circumstances surrounding our predecessor's trading strategy prior to bankruptcy filings; (ii)&amp;#160;investigate the circumstances surrounding certain insider transactions and the formation of SemGroup Energy Partners L.P. (a former subsidiary); (iii)&amp;#160;investigate the circumstances surrounding the potential improper use of borrowed funds and funds generated from operations and the liquidation of assets to satisfy margin calls related to our predecessor's trading strategy and that of certain entities owned or controlled by former officers and directors of the general partner of SemGroup, L.P.; (iv)&amp;#160;determine whether any directors, officers or employees of the general partner of SemGroup, L.P. participated in fraud, dishonesty, incompetence, misconduct, mismanagement, or irregularity in the management of our affairs; and (v)&amp;#160;determine whether the SemGroup debtor estates have causes of action against current or former officers, directors, or employees of the general partner of SemGroup, L.P. arising from such participation. The examiner&amp;#8217;s report was filed with the bankruptcy court on April&amp;#160;15, 2009.&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:6px;padding-left:84px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;Certain current and prior employees of the general partner of SemGroup, L.P. are referenced in the examiner&amp;#8217;s report and the report&amp;#8217;s conclusions may suggest possible civil or criminal liability on their part. To the extent such claims exist, they are property of a litigation trust that was established for the benefit of pre-petition creditors pursuant to the Plan of Reorganization, and are not property of the reorganized SemGroup Corporation. This litigation trust is pursuing claims against certain former officers, at its own expense. We may incur expenses, which are not expected to be material, related to information and document requests of the litigation trust related to such claims. Any indemnification obligations to such officers by SemGroup, L.P. were discharged under the Plan of Reorganization. &lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:6px;padding-left:84px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;font-style:italic;"&gt;CFTC&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;. On June&amp;#160;19, 2008, we received a request for voluntary production from the Commodity Futures Trading Commission (&amp;#8220;CFTC&amp;#8221;). Subsequent to the bankruptcy filings, the CFTC sent other requests for voluntary production. The CFTC has also served subpoenas upon us requiring us to produce various documents and for the depositions of our representatives. We continue to comply with the CFTC&amp;#8217;s requests. We are unaware of any currently pending formal charges against us by the CFTC.&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:6px;padding-left:84px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;font-style:italic;"&gt;DOJ&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;. On July&amp;#160;15, 2008, we received a subpoena from the Department of Justice (&amp;#8220;DOJ&amp;#8221;) directing us to produce documents responsive to the subpoena. We contacted the DOJ regarding the subpoena and the DOJ verbally voluntarily stayed compliance with the subpoena. We have not produced any documents to the DOJ and, to our knowledge, the DOJ is not currently pursuing any such production. We are unaware of any currently pending formal charges against us by the DOJ.&lt;/font&gt;&lt;/div&gt;&lt;table cellpadding="0" cellspacing="0" style="padding-top:16px;font-family:Times New Roman; font-size:10pt;"&gt;&lt;tr&gt;&lt;td style="width:84px;" rowspan="1" colspan="1"&gt;&lt;/td&gt;&lt;td rowspan="1" colspan="1"&gt;&lt;/td&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td style="vertical-align:top" rowspan="1" colspan="1"&gt;&lt;div style="line-height:120%;font-size:10pt;padding-left:36px;"&gt;&lt;font style="font-family:inherit;font-size:10pt;font-style:italic;"&gt;(c) &lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;td style="vertical-align:top;" rowspan="1" colspan="1"&gt;&lt;div style="line-height:120%;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;font-style:italic;"&gt;Claims reconciliation process&lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;div style="line-height:120%;padding-top:6px;padding-left:84px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;A large number of parties have made claims against us for obligations alleged to have been incurred prior to our predecessor's bankruptcy filing. On September&amp;#160;15, 2010, the bankruptcy court entered an order estimating the contingent, unliquidated and disputed claims and authorizing distributions to holders of allowed claims. Pursuant to that order we have begun making distributions to the claimants. We continue to attempt to settle unresolved claims.&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:6px;padding-left:84px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;Pursuant to the Plan of Reorganization, we committed to settle authorized and allowed bankruptcy claims by paying a specified amount of cash, issuing a specified number of warrants, and issuing a specified number of shares of SemGroup Corporation common stock.&amp;#160;We do not believe the resolution of the remaining outstanding claims will exceed the total amount of consideration established under the Plan of Reorganization for all claimants; instead, the resolution of the remaining claims in some cases will impact the relative share of the established pool of common stock and warrants that certain claimants receive.&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:6px;padding-left:84px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;However, under certain circumstances we could be required to pay additional funds to settle the specified group of claims to be settled with cash. Pursuant to the Plan of Reorganization, a specified amount of restricted cash was set aside at the Emergence Date, which we expect to be sufficient to settle this group of claims.&amp;#160;Since the Emergence Date, we have made significant progress in resolving these claims, and we continue to believe that the cash set aside at the Emergence Date will be sufficient to settle these claims.&amp;#160;However, we have not yet reached a resolution of all of these claims, and if the total settlement amount of all of these claims exceeds the specified amount, we will be required to pay additional funds to satisfy the total settlement amount for this specified group of claims.&amp;#160;If this were to become probable of occurring, we would be required to record a liability and a corresponding expense.&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:18px;padding-left:36px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;"&gt;Blueknight claim&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:6px;padding-left:36px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;Blueknight Energy Partners, L.P. (&amp;#8220;Blueknight&amp;#8221;), which was formerly a subsidiary of SemGroup, together with other entities related to Blueknight, entered into a Shared Services Agreement on April&amp;#160;7, 2009, with SemCrude, L.P. and SemManagement, L.L.C. (which are currently subsidiaries of SemGroup). The services provided by SemCrude to Blueknight under this agreement included the coordination of movement of crude oil belonging to Blueknight&amp;#8217;s customers and the operation of Blueknight&amp;#8217;s Oklahoma pipeline system and its Cushing, Oklahoma terminal. Under the subsequent amendments to the agreements beginning in May 2010, certain of these services were phased out, and Blueknight began to manage the movement of its crude oil and the operation of its Cushing terminal.&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:12px;padding-left:36px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;In a letter dated August&amp;#160;18, 2011, Blueknight claimed that SemCrude owes Blueknight approximately &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;141,000&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt; barrels of crude oil. We responded to Blueknight&amp;#8217;s letter denying their charges and requesting documentation from Blueknight of its claim. On February&amp;#160;14, 2012, after months of interaction between the parties through which we requested Blueknight to substantiate its claim, Blueknight filed suit against us in the District Court of Oklahoma County, Oklahoma. On May&amp;#160;1, 2012, the court approved our motion to transfer this case to Tulsa County, Oklahoma. On July&amp;#160;2, 2012, the Tulsa County District Court appointed a Special Master to conduct a review of whether Blueknight is missing &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;141,000&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt; barrels of crude oil from operations occurring during the months of April through June, 2010. On June 11, 2013, the Special Master's Report was finalized and filed with the District Court, confirming a shortage in Blueknight's Cushing terminal and Oklahoma pipeline system.&amp;#160; Discovery will proceed in the District Court where we will seek documentation and testimony on the treatment of the missing oil.&amp;#160; We will continue to defend our position; however, we cannot predict the outcome.&amp;#160; &lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:18px;padding-left:36px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;"&gt;Environmental&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:6px;padding-left:36px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;We may from time to time experience leaks of petroleum products from our facilities and, as a result of which, we may incur remediation obligations or property damage claims. In addition, we are subject to numerous environmental regulations. Failure to comply with these regulations could result in the assessment of fines or penalties by regulatory authorities.&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:12px;padding-left:36px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;The Kansas Department of Health and Environment (&amp;#8220;the KDHE&amp;#8221;) initiated discussions during our bankruptcy proceeding regarding &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;six&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt; of our sites in Kansas (&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;five&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt; owned by Crude and &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;one&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt; owned by SemGas) that KDHE believes, based on their historical use, may have soil or groundwater contamination in excess of state standards. KDHE sought our agreement to undertake assessments of these sites to determine whether they are contaminated. We reached an agreement with KDHE on this matter and entered into a Consent Agreement and Final Order with KDHE to conduct environmental assessments on the sites and to pay KDHE&amp;#8217;s costs associated with their oversight of this matter. We have conducted Phase II investigations at all sites and results indicate that &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;four&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt; of the sites have limited amounts of soil contamination that will require remediation and ground water contamination that may require further delineation and/or ongoing monitoring. Work plans have been submitted to, and approved by, the KDHE. We do not anticipate any penalties or fines for these historical sites.&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:12px;padding-left:36px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;A water pipeline break occurred at a SemCAMS facility during August 2010. This resulted in a spill of material that was predominantly salt water containing a small amount of hydrocarbons. The incident was investigated by Environment Canada and Alberta Environment. On February&amp;#160;14, 2012, charges were filed against SemCAMS by the Federal Government of Canada (Department of Fisheries) and the Province of Alberta (Alberta Environment) in connection with this incident. We have reviewed disclosure received from the agencies and engaged our expert to assist us in formulating our response. Our expert's report has been completed and was delivered to the crown in April 2013. Although it is not possible to predict the outcome of these proceedings, we accrued a liability for estimated fines and environmental contributions of &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;$0.4 million&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt; in December 2010, which we still carry on our books at &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;June&amp;#160;30, 2013&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;.&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:18px;padding-left:36px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;"&gt;Other matters&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:6px;padding-left:36px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;We are party to various other claims, legal actions, and complaints arising in the ordinary course of business. In the opinion of our management, the ultimate resolution of these claims, legal actions and complaints, after consideration of amounts accrued, insurance coverage and other arrangements, will not have a material adverse effect on our consolidated financial position, results of operations or cash flows. However, the outcome of such matters is inherently uncertain, and estimates of our consolidated liabilities may change materially as circumstances develop.&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:8px;padding-top:18px;padding-left:36px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;"&gt;Asset retirement obligations&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-left:36px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;We will be required to incur significant removal and restoration costs when we retire our natural gas gathering and processing facilities in Canada. We have recorded an asset retirement obligation liability of &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;$40.5 million&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt; at &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;June&amp;#160;30, 2013&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;, which is included within other noncurrent liabilities on our condensed consolidated balance sheets. This amount was calculated using the &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;$102.0 million&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt; cost we estimate we would incur to retire these facilities, discounted based on our risk-adjusted cost of borrowing and the estimated timing of remediation.&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:12px;padding-left:36px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;The calculation of the liability for an asset retirement obligation requires the use of significant estimates, including those related to the length of time before the assets will be retired, cost inflation over the assumed life of the assets, actual remediation activities to be required, and the rate at which such obligations should be discounted. Future changes in these estimates could result in material changes in the value of the recorded liability.
