The Company anticipates using these investments to satisfy its obligations under its unfunded, nonqualified benefit plans for executive officers and certain key management employees, and invests in these fixed-income and equity securities for the purpose of earning investment returns and capital appreciation. These investments, which totaled $40.3&amp;#160;million, $20.2&amp;#160;million and $39.5&amp;#160;million, as of June&amp;#160;30, 2011 and 2010, and December&amp;#160;31, 2010, respectively, are classified as Investments on the Consolidated Balance Sheets. The fair value of these investments decreased $1.3&amp;#160;million (before tax) for the three months ended June&amp;#160;30, 2011, and increased $790,000 (before tax) for the six months ended June&amp;#160;30, 2011. The decrease in the fair value of these investments for the three and six months ended June&amp;#160;30, 2010, was $1.8&amp;#160;million (before tax) and $970,000 (before tax), respectively. The change in fair value, which is considered part of the cost of the plan, is classified in operation and maintenance expense on the Consolidated Statements of Income.&lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;/div&gt;&lt;div style="TEXT-INDENT: 0pt; DISPLAY: block"&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;table style="FONT-FAMILY: times new roman; FONT-SIZE: 10pt" border="0" cellspacing="0" cellpadding="0" width="100%" align="center"&gt;&lt;tr valign="top"&gt;&lt;td style="WIDTH: 36pt"&gt;&lt;div&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;&amp;#160; &lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;td&gt;&lt;div align="left"&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;The Company did not elect the fair value option for its remaining available-for-sale securities, which include auction rate securities, mortgage-backed securities and U.S. Treasury securities.

Montana-Dakota requested a total increase of $15.4&amp;#160;million annually or approximately 14&amp;#160;percent above current rates. The requested increase included the investment in infrastructure upgrades, recovery of the investment in renewable generation, the costs associated with Big Stone Station II and the significant loss of wholesale sales margins. In June&amp;#160;2010, the NDPSC approved an interim increase of $7.6&amp;#160;million effective with service rendered June&amp;#160;18, 2010. In June 2010, Montana-Dakota and the NDPSC Advocacy Staff filed a partial settlement agreement agreeing to an overall rate of return and a sharing of earnings over a specified return on equity. In July 2010, Montana-Dakota filed an amendment to its application to exclude the development costs associated with Big Stone Station II because of a settlement agreement approved by the NDPSC that provided for recovery of such development costs. In November 2010, Montana-Dakota and the NDPSC Advocacy Staff filed a second settlement agreement resolving certain issues raised by the NDPSC Advocacy Staff in its investigation of the rate increase application. Montana-Dakota revised its requested rate increase to $8.8&amp;#160;million annually or 7.7&amp;#160;percent as a result of the settlements, the exclusion of the Big Stone Station II development costs and other adjustments. The NDPSC Advocacy Staff sought reductions of $8.3&amp;#160;million annually from Montana-Dakota's requested increase. A hearing on the application was held in November 2010. On March&amp;#160;14, 2011, Montana-Dakota, the NDPSC Advocacy Staff and the Missouri Valley Resource Council filed a settlement agreement that resolved all outstanding issues in the case, resulting in an increase of $7.6&amp;#160;million annually. On June&amp;#160;8, 2011, the NDPSC approved the settlement agreements. Final rates were implemented effective with service rendered July&amp;#160;22, 2011.&lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;/div&gt;&lt;div style="TEXT-INDENT: 0pt; DISPLAY: block"&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;table style="FONT-FAMILY: times new roman; FONT-SIZE: 10pt" border="0" cellspacing="0" cellpadding="0" width="100%" align="center"&gt;&lt;tr valign="top"&gt;&lt;td style="WIDTH: 36pt"&gt;&lt;div&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;&amp;#160; &lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;td&gt;&lt;div align="left"&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;On May&amp;#160;20, 2011, Montana-Dakota filed an application with the NDPSC requesting advance determination of prudence that the addition of the air quality control system at the Big Stone Station, to comply with the Clean Air Act and the South Dakota Regional Haze Implementation Plan, is reasonable and prudent.

The turbine will be located on company owned property that is adjacent to Montana-Dakota's Heskett Generating Station near Mandan, North Dakota, and is required to meet the capacity requirements of Montana-Dakota's integrated electric system service customers. The capacity will be a partial replacement for third party contract capacity expiring in 2015. Project cost is estimated to be $85.6&amp;#160;million. An order is expected in the first quarter of 2012.&lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;/div&gt;&lt;div style="TEXT-INDENT: 0pt; DISPLAY: block"&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;table style="FONT-FAMILY: times new roman; FONT-SIZE: 10pt" border="0" cellspacing="0" cellpadding="0" width="100%" align="center"&gt;&lt;tr valign="top"&gt;&lt;td style="WIDTH: 36pt"&gt;&lt;div&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;&amp;#160; &lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;td&gt;&lt;div align="left"&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;In August 2010, Montana-Dakota filed an application with the MTPSC for an electric rate increase. Montana-Dakota requested a total increase of $5.5&amp;#160;million annually or approximately 13&amp;#160;percent above current rates. The requested increase included the investment in infrastructure upgrades, recovery of the investment in renewable generation, the costs associated with Big Stone Station II and the significant loss of wholesale sales margins. Montana-Dakota requested an interim increase of $3.1&amp;#160;million or approximately 7.4 percent.

Centennial Resources sold CEM in July 2007 to Bicent Power LLC, which provided a $10&amp;#160;million bank letter of credit to Centennial in support of the guarantee obligation, which letter of credit expired in November 2010. In February 2009, Centennial received a Notice and Demand from LPP under the guaranty agreement alleging that CEM did not meet certain of its obligations under the construction contract and demanding that Centennial indemnify LPP against all losses, damages, claims, costs, charges and expenses arising from CEM's alleged failures. In December&amp;#160;2009, LPP submitted a demand for arbitration of its dispute with CEM to the American Arbitration Association. The demand seeks compensatory damages of $149.7 million. LPP's notice of demand for arbitration also demanded performance of the guarantee by Centennial. In June 2010, CEM and Bicent Power LLC made a demand on Centennial Resources for indemnification under the 2007 purchase and sale agreement for indemnifiable losses, including defense fees and costs which CEM and Bicent Power LLC have stated are more than $10.0&amp;#160;million, arising from LPP's arbitration demand and related to Centennial Resources' ownership of CEM prior to its sale to Bicent Power LLC. The Company believes the claims against Centennial and Centennial Resources are without merit and intends to vigorously defend against such claims. Centennial and Centennial Resources filed a complaint with the Supreme Court of the State of New York in November 2010, against CEM and Bicent Power LLC seeking damages for breach of contract and other relief including specific performance of the 2007 purchase and sale agreement allowing for Centennial Resources' participation in the arbitration proceeding and replacement of the letter of credit. On January&amp;#160;28, 2011, CEM and Bicent Power LLC filed a motion to dismiss the complaint filed by Centennial and Centennial Resources. On July&amp;#160;6, 2011, the Supreme Court of the State of New York entered an order granting CEM's motion to dismiss the complaint against it for lack of jurisdiction. The Supreme Court of the State of New York also dismissed one of the claims against Bicent Power LLC but denied Bicent Power LLC's motion to dismiss the remaining claims against it including the claims for breach of contract damages and specific performance of the 2007 purchase and sale agreement. The arbitration hearing on LPP's claim is currently scheduled for late in the third quarter of 2011.&lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;/div&gt;&lt;div style="TEXT-INDENT: 0pt; DISPLAY: block"&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;table border="0" cellspacing="0" cellpadding="0" width="100%" align="center"&gt;&lt;tr valign="top"&gt;&lt;td style="WIDTH: 36pt"&gt;&lt;div&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;&amp;#160; &lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;td&gt;&lt;div align="left"&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;&lt;font style="FONT-STYLE: italic; DISPLAY: inline; FONT-WEIGHT: bold"&gt;Construction Materials&lt;/font&gt;&lt;font style="DISPLAY: inline; FONT-WEIGHT: bold"&gt;&amp;#160;&lt;/font&gt;In 2009, LTM provided pavement work under a subcontract for reconstruction at the Klamath Falls Airport owned by the City of Klamath Falls, Oregon. In October 2010, the City of Klamath Falls filed a complaint in Oregon Circuit Court against the project's general contractor alleging the work performed by LTM is defective. The general contractor tendered the defense and indemnity of the claim to LTM and its insurance carrier. On January&amp;#160;18, 2011, the general contractor served a third party complaint against LTM seeking indemnity and contribution for damages imposed on the general contractor. LTM filed a fourth-party complaint seeking contribution and indemnity for damages imposed on LTM against the project engineer firm which prepared the specifications for the airport runway. LTM's insurance carrier accepted defense of the complaint against the general contractor and the third party complaint against LTM subject to reservation of its rights under the applicable insurance policy. Damages, including removal and replacement of the paved runway, were estimated by the plaintiff in its complaint as $6.0&amp;#160;million to $11.0&amp;#160;million. The Oregon Circuit Court granted a motion by LTM to dismiss certain of the plaintiff's claims relating to approximately $5.0&amp;#160;million of damages but allowed the plaintiff to amend its complaint. In its amended complaint, the plaintiff asserts new claims with estimated damages of $21.9&amp;#160;million plus interest and attorney fees. LTM believes its work met the specifications of the subcontract and expects to vigorously defend against the claims.&lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;/div&gt;&lt;div style="TEXT-INDENT: 0pt; DISPLAY: block"&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;table border="0" cellspacing="0" cellpadding="0" width="100%" align="center"&gt;&lt;tr valign="top"&gt;&lt;td style="WIDTH: 36pt"&gt;&lt;div&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;&amp;#160; &lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;td&gt;&lt;div align="left"&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;&lt;font style="FONT-STYLE: italic; DISPLAY: inline; FONT-WEIGHT: bold"&gt;Natural Gas Gathering Operations&lt;/font&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;&amp;#160;&lt;/font&gt;In January 2010, SourceGas filed an application with the Colorado State District Court to compel Bitter Creek to arbitrate a dispute regarding operating pressures under a natural gas gathering contract on one of Bitter Creek's pipeline gathering systems in Montana. Bitter Creek resisted the application and sought a declaratory order interpreting the gathering contract. In May 2010, the Colorado State District Court granted the application and ordered Bitter Creek into arbitration. An arbitration hearing was held in August 2010. In October 2010, Bitter Creek was notified that the arbitration panel issued an award in favor of SourceGas for approximately $26.6&amp;#160;million. As a result, Bitter Creek, which is included in the pipeline and energy services segment, recorded a $26.6&amp;#160;million charge ($16.5&amp;#160;million after tax) in the third quarter of 2010. On April&amp;#160;20, 2011, the Colorado State District Court entered an order denying a motion by Bitter Creek to vacate the arbitration award and granting a motion by SourceGas to confirm the arbitration award as a court judgment. The Colorado State District Court also awarded $293,000 to SourceGas for legal fees and expense. Bitter Creek filed an appeal from the Colorado State District Court's order and judgment to the Colorado Court of Appeals on April&amp;#160;28, 2011.&lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;/div&gt;&lt;div style="TEXT-INDENT: 0pt; DISPLAY: block"&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;table border="0" cellspacing="0" cellpadding="0" width="100%" align="center"&gt;&lt;tr valign="top"&gt;&lt;td style="WIDTH: 36pt"&gt;&lt;div&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;&amp;#160; &lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;td&gt;&lt;div align="left"&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;In related matters, Noble Energy, Inc. made a written demand in December 2010, to Bitter Creek and SourceGas for arbitration under the gathering contract between Bitter Creek and SourceGas. Noble Energy, Inc. contends it is a third party beneficiary of the contract and alleged it is damaged by the increased operating pressures demanded by SourceGas on the natural gas gathering system. Bitter Creek filed a complaint in Colorado State District Court to enjoin arbitration by Noble Energy, Inc. On July&amp;#160;8, 2011, Bitter Creek and Noble Energy, Inc. entered into a settlement agreement to dismiss all claims between them without prejudice including withdrawal of Noble Energy, Inc.'s demand for arbitration. In July 2010, Omimex Canada, Ltd. filed a complaint against Bitter Creek in Montana District Court alleging Bitter Creek breached a separate gathering contract with Omimex Canada, Ltd. as a result of the increased operating pressures on the same natural gas gathering system. Omimex Canada, Ltd. seeks unspecified damages and injunctive relief.&lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;/div&gt;&lt;div style="TEXT-INDENT: 0pt; DISPLAY: block"&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;table border="0" cellspacing="0" cellpadding="0" width="100%" align="center"&gt;&lt;tr valign="top"&gt;&lt;td style="WIDTH: 36pt"&gt;&lt;div&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;&amp;#160; &lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;td&gt;&lt;div align="left"&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;&lt;font style="FONT-STYLE: italic; DISPLAY: inline; FONT-WEIGHT: bold"&gt;Natural Gas Distribution&lt;/font&gt;&lt;font style="font-family: temp;"&gt;&lt;font style="DISPLAY: inline; FONT-WEIGHT: bold"&gt; &lt;font style="FONT-WEIGHT: normal"&gt;The WUTC on March 21, 2011, filed a complaint against Cascade, alleging pipeline safety violations in the operation of its natural gas distribution system.

Cascade and the WUTC staff entered into a settlement agreement &lt;/font&gt;&lt;/font&gt;&lt;/font&gt;&lt;font style="FONT-WEIGHT: normal"&gt;filed with the WUTC&lt;font style="DISPLAY: inline; FONT-WEIGHT: normal"&gt; on July&amp;#160;13, 2011, which was approved by the WUTC on August&amp;#160;3, 2011. The settlement provides for an immediate cash payment by Cascade of $425,000 and suspended penalties totaling up to $1.8&amp;#160;million which Cascade will be required to pay if it fails to comply with action items for remediation of violations and implementation of safety program improvements within timelines specified in the agreement. The Company's leadership is committed to pipeline safety compliance and over the past year and a half substantial resources have been invested by Cascade to improve pipeline safety documentation and procedures. Cascade recognized certain compliance issues and has been working with the WUTC to become fully compliant. Cascade believes most of the violations have been or are in the process of being remedied and intends to make significant additional technological and other investments over the next year to comply with the requirements of the settlement agreement and improve its compliance procedures and results.&lt;/font&gt;&lt;/font&gt;&lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;/div&gt;&lt;div style="TEXT-INDENT: 0pt; DISPLAY: block"&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;table border="0" cellspacing="0" cellpadding="0" width="100%" align="center"&gt;&lt;tr valign="top"&gt;&lt;td style="WIDTH: 36pt"&gt;&lt;div&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;&amp;#160; &lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;td&gt;&lt;div align="left"&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;The Company also is involved in other legal actions in the ordinary course of its business.

The riverbed site is part of the Portland, Oregon, Harbor Superfund Site. The EPA wants responsible parties to share in the cleanup of sediment contamination in the Willamette River. To date, costs of the overall remedial investigation and feasibility study of the harbor site are being recorded, and initially paid, through an administrative consent order by the LWG, a group of several entities, which does not include Knife River &amp;#8211; Northwest or Georgia-Pacific West, Inc. Investigative costs are indicated to be in excess of $70&amp;#160;million. It is not possible to estimate the cost of a corrective action plan until the remedial investigation and feasibility study have been completed, the EPA has decided on a strategy and a ROD has been published. Corrective action will be taken after the development of a proposed plan and ROD on the harbor site is issued. Knife River &amp;#8211; Northwest also received notice in January 2008 that the Portland Harbor Natural Resource Trustee Council intends to perform an injury assessment to natural resources resulting from the release of hazardous substances at the Harbor Superfund Site. The Portland Harbor Natural Resource Trustee Council indicates the injury determination is appropriate to facilitate early settlement of damages and restoration for natural resource injuries. It is not possible to estimate the costs of natural resource damages until an assessment is completed and allocations are undertaken.&lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;/div&gt;&lt;div style="TEXT-INDENT: 0pt; DISPLAY: block"&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;table border="0" cellspacing="0" cellpadding="0" width="100%" align="center"&gt;&lt;tr valign="top"&gt;&lt;td style="WIDTH: 36pt"&gt;&lt;div&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;&amp;#160; &lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;td&gt;&lt;div align="left"&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;Based upon a review of the Portland Harbor sediment contamination evaluation by the Oregon DEQ and other information available, Knife River &amp;#8211; Northwest does not believe it is a Responsible Party. In addition, Knife River &amp;#8211; Northwest has notified Georgia-Pacific West, Inc., that it intends to seek indemnity for liabilities incurred in relation to the above matters pursuant to the terms of their sale agreement. Knife River &amp;#8211; Northwest has entered into an agreement tolling the statute of limitations in connection with the LWG's potential claim for contribution to the costs of the remedial investigation and feasibility study. By letter in March 2009, LWG stated its intent to file suit against Knife River &amp;#8211; Northwest and others to recover LWG's investigation costs to the extent Knife River &amp;#8211; Northwest cannot demonstrate its non-liability for the contamination or is unwilling to participate in an alternative dispute resolution process that has been established to address the matter. At this time, Knife River &amp;#8211; Northwest has agreed to participate in the alternative dispute resolution process.&lt;/font&gt;&lt;/div&gt;&lt;div align="left"&gt;&amp;#160;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;/div&gt;&lt;div&gt;&lt;table border="0" cellspacing="0" cellpadding="0" width="100%" align="center"&gt;&lt;tr valign="top"&gt;&lt;td style="WIDTH: 36pt"&gt;&lt;div&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;&amp;#160; &lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;td&gt;&lt;div align="left"&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;The Company believes it is not probable that it will incur any material environmental remediation costs or damages in relation to the above referenced administrative action.&lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;/div&gt;&lt;div style="TEXT-INDENT: 0pt; DISPLAY: block"&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;table border="0" cellspacing="0" cellpadding="0" width="100%" align="center"&gt;&lt;tr valign="top"&gt;&lt;td style="WIDTH: 36pt"&gt;&lt;div&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;&amp;#160; &lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;td&gt;&lt;div align="left"&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;&lt;font style="FONT-STYLE: italic; DISPLAY: inline; FONT-WEIGHT: bold"&gt;Manufactured Gas Plant Sites &lt;/font&gt;There are three claims against Cascade for cleanup of environmental contamination at manufactured gas plant sites operated by Cascade's predecessors.&lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;/div&gt;&lt;div style="TEXT-INDENT: 0pt; DISPLAY: block"&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;table border="0" cellspacing="0" cellpadding="0" width="100%" align="center"&gt;&lt;tr valign="top"&gt;&lt;td style="WIDTH: 36pt"&gt;&lt;div&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;&amp;#160; &lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;td&gt;&lt;div align="left"&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;The first claim is for soil and groundwater contamination at a site in Oregon and was received in 1995. There are PRPs in addition to Cascade that may be liable for cleanup of the contamination. Some of these PRPs have shared in the investigation costs. It is expected that these and other PRPs will share in the cleanup costs. Several alternatives for cleanup have been identified, with preliminary cost estimates ranging from approximately $500,000 to $11.0&amp;#160;million. An ecological risk assessment draft report was submitted to the Oregon DEQ in June 2009. The assessment showed no unacceptable risk to the aquatic ecological receptors present in the shoreline along the site and concluded that no further ecological investigation is necessary. The report is being reviewed by the Oregon DEQ. It is anticipated the Oregon DEQ will recommend a cleanup alternative for the site after it completes its review of the report. It is not known at this time what share of the cleanup costs will actually be borne by Cascade; however, Cascade anticipates its proportional share could be approximately fifty percent.&lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;/div&gt;&lt;div style="TEXT-INDENT: 0pt; DISPLAY: block"&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;table border="0" cellspacing="0" cellpadding="0" width="100%" align="center"&gt;&lt;tr valign="top"&gt;&lt;td style="WIDTH: 36pt"&gt;&lt;div&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;&amp;#160; &lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;td&gt;&lt;div align="left"&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;The second claim is for contamination at a site in Washington and was received in 1997. A preliminary investigation has found soil and groundwater at the site contain contaminants requiring further investigation and cleanup. EPA conducted a Targeted Brownfields Assessment of the site and released a report summarizing the results of that assessment in August 2009. The assessment confirms that contaminants have affected soil and groundwater at the site, as well as sediments in the adjacent Port Washington Narrows. Alternative remediation options have been identified with preliminary cost estimates ranging from $340,000 to $6.4&amp;#160;million. Data developed through the assessment and previous investigations indicates the contamination likely derived from multiple, different sources and multiple current and former owners of properties and businesses in the vicinity of the site may be responsible for the contamination. Cascade received notice in April 2010, that the Washington Department of Ecology has determined that Cascade is a PRP for release of hazardous substances at the site. In October 2010, Cascade received notice from the United States Coast Guard that a hazardous substance appearing to be manufactured gas plant waste was released into the waterway from an abandoned pipe located on the shoreline in the vicinity of the former manufactured gas plant. Cascade subsequently received an administrative order from the United States Coast Guard requiring Cascade to remove the abandoned pipe and conduct other associated time-critical actions. The work satisfying the administrative order was completed by Cascade in November 2010. It is expected that subsequent remedial action at the site will be conducted under the oversight of the EPA. On June&amp;#160;27, 2011, the EPA provided Cascade with a draft administrative settlement agreement and statement of work for performance of a remediation investigation and feasibility study of the site. Cascade intends to meet with the EPA and discuss the draft agreement and statement of work with the intent of reaching consensus on the scope and schedule for the remediation investigation and feasibility study. Cascade has reserved $6.4&amp;#160;million for remediation of this site. In April 2010, Cascade filed a petition with the WUTC for authority to defer the costs, which are included in other noncurrent assets, incurred in relation to the environmental remediation of this site until the next general rate case. The WUTC approved the petition in September 2010, subject to conditions set forth in the order.&lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;/div&gt;&lt;div style="TEXT-INDENT: 0pt; DISPLAY: block"&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;table border="0" cellspacing="0" cellpadding="0" width="100%" align="center"&gt;&lt;tr valign="top"&gt;&lt;td style="WIDTH: 36pt"&gt;&lt;div&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;&amp;#160; &lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;td&gt;&lt;div align="left"&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;The third claim is also for contamination at a site in Washington. Cascade received notice from a party in May 2008 that Cascade may be a PRP, along with other parties, for contamination from a manufactured gas plant owned by Cascade and its predecessor from about 1946 to 1962. The notice indicates that current estimates to complete investigation and cleanup of the site exceed $8.0&amp;#160;million. Other PRPs have reached an agreed order and work plan with the Washington Department of Ecology for completion of a remedial investigation and feasibility study for the site. The remediation investigation and feasibility study report are expected to be completed by late 2011. There is currently not enough information available to estimate the potential liability to Cascade associated with this claim although Cascade believes its proportional share of any liability will be relatively small in comparison to other PRPs. The plant manufactured gas from coal between approximately 1890 and 1946. In 1946, shortly after Cascade's predecessor acquired the plant, it converted the plant to a propane-air gas facility. There are no documented wastes or by-products resulting from the mixing or distribution of propane-air gas.&lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;/div&gt;&lt;div style="TEXT-INDENT: 0pt; DISPLAY: block"&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;table border="0" cellspacing="0" cellpadding="0" width="100%" align="center"&gt;&lt;tr valign="top"&gt;&lt;td style="WIDTH: 36pt"&gt;&lt;div&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;&amp;#160; &lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;td&gt;&lt;div align="left"&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;Cascade has received notices from certain of its insurance carriers that they will participate in defense of Cascade for these contamination claims subject to full and complete reservations of rights and defenses to insurance coverage. To the extent these claims are not covered by insurance, Cascade will seek recovery through the OPUC and WUTC of remediation costs in its natural gas rates charged to customers.&lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;/div&gt;&lt;div style="TEXT-INDENT: 0pt; DISPLAY: block"&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;table border="0" cellspacing="0" cellpadding="0" width="100%" align="center"&gt;&lt;tr valign="top"&gt;&lt;td style="WIDTH: 36pt"&gt;&lt;div&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;&amp;#160; &lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;td&gt;&lt;div align="left"&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt; FONT-WEIGHT: bold"&gt;Guarantees&lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;/div&gt;&lt;div&gt;&lt;table border="0" cellspacing="0" cellpadding="0" width="100%" align="center"&gt;&lt;tr valign="top"&gt;&lt;td style="WIDTH: 36pt"&gt;&lt;div&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;&amp;#160; &lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;td&gt;&lt;div align="left"&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;Centennial guaranteed CEM's obligations under a construction contract.

There is no fixed maximum amount guaranteed in relation to the natural gas and oil swap and collar agreements as the amount of the obligation is dependent upon natural gas and oil commodity prices. The amount of hedging activity entered into by the subsidiary is limited by corporate policy. The guarantees of the natural gas and oil swap and collar agreements at June&amp;#160;30, 2011, expire in the years ranging from 2011 to 2012; however, Fidelity continues to enter into additional hedging activities and, as a result, WBI&amp;#160;Holdings from time to time may issue additional guarantees on these hedging obligations. The amount outstanding by Fidelity was $13.5&amp;#160;million and was reflected on the Consolidated Balance Sheet, at June&amp;#160;30, 2011. In the event Fidelity defaults under its obligations, WBI&amp;#160;Holdings would be required to make payments under its guarantees.&lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;/div&gt;&lt;div style="TEXT-INDENT: 0pt; DISPLAY: block"&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;table border="0" cellspacing="0" cellpadding="0" width="100%" align="center"&gt;&lt;tr valign="top"&gt;&lt;td style="WIDTH: 36pt"&gt;&lt;div&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;&amp;#160; &lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;td&gt;&lt;div align="left"&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;Certain subsidiaries of the Company have outstanding guarantees to third parties that guarantee the performance of other subsidiaries of the Company. These guarantees are related to construction contracts, natural gas transportation and sales agreements, gathering contracts, a conditional purchase agreement and certain other guarantees. At June&amp;#160;30, 2011, the fixed maximum amounts guaranteed under these agreements aggregated $127.6&amp;#160;million. The amounts of scheduled expiration of the maximum amounts guaranteed under these agreements aggregate $27.8&amp;#160;million in 2011; $73.4&amp;#160;million in 2012; $18.2&amp;#160;million in 2013; $300,000 in 2014; $100,000 in 2015; $100,000 in 2016; $800,000 in 2018; $300,000 in 2019; $2.6&amp;#160;million, which is subject to expiration on a specified number of days after the receipt of written notice; and $4.0&amp;#160;million, which has no scheduled maturity date. The amount outstanding by subsidiaries of the Company under the above guarantees was $1.3&amp;#160;million and was reflected on the Consolidated Balance Sheet at June&amp;#160;30, 2011. In the event of default under these guarantee obligations, the subsidiary issuing the guarantee for that particular obligation would be required to make payments under its guarantee.&lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;/div&gt;&lt;div style="TEXT-INDENT: 0pt; DISPLAY: block"&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;table border="0" cellspacing="0" cellpadding="0" width="100%" align="center"&gt;&lt;tr valign="top"&gt;&lt;td style="WIDTH: 36pt"&gt;&lt;div&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;&amp;#160; &lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;td&gt;&lt;div align="left"&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;Certain subsidiaries have outstanding letters of credit to third parties related to insurance policies, natural gas transportation agreements and other agreements, some of which are guaranteed by other subsidiaries of the Company.

In the event of Prairielands' default in its payment obligations, WBI Holdings would be required to make payment under its guarantee. The amount outstanding by Prairielands under the above guarantee was $1.4&amp;#160;million. The amount outstanding under this guarantee was not reflected on the Consolidated Balance Sheet at June&amp;#160;30, 2011, because this intercompany transaction was eliminated in consolidation.&lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;/div&gt;&lt;div style="TEXT-INDENT: 0pt; DISPLAY: block"&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;table border="0" cellspacing="0" cellpadding="0" width="100%" align="center"&gt;&lt;tr valign="top"&gt;&lt;td style="WIDTH: 36pt"&gt;&lt;div&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;&amp;#160; &lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;td&gt;&lt;div align="left"&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;In addition, Centennial, Knife River and MDU Construction Services have issued guarantees to third parties related to the routine purchase of maintenance items, materials and lease obligations for which no fixed maximum amounts have been specified. These guarantees have no scheduled maturity date. In the event a subsidiary of the Company defaults under these obligations, Centennial, Knife River and MDU Construction Services would be required to make payments under these guarantees.

The guidance requires separate disclosures of the amounts of transfers in and out of Level&amp;#160;1 and Level&amp;#160;2 fair value measurements and a description of the reason for such transfers. In the reconciliation for Level&amp;#160;3 fair value measurements using significant unobservable inputs, information about purchases, sales, issuances and settlements shall be presented separately. These disclosures are required for interim and annual reporting periods and were effective for the Company on January&amp;#160;1, 2010, except for the disclosures related to the purchases, sales, issuances and settlements in the roll forward activity of Level 3 fair value measurements, which were effective on January&amp;#160;1, 2011. The guidance requires additional disclosures, but it will not impact the Company's financial position, results of operations or cash flows.&lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;/div&gt;&lt;div style="TEXT-INDENT: 0pt; DISPLAY: block"&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;table style="FONT-FAMILY: times new roman; FONT-SIZE: 10pt" border="0" cellspacing="0" cellpadding="0" width="100%" align="center"&gt;&lt;tr valign="top"&gt;&lt;td style="WIDTH: 36pt"&gt;&lt;div&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;&amp;#160; &lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;td&gt;&lt;div align="left"&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;&lt;font style="FONT-STYLE: italic; DISPLAY: inline; FONT-WEIGHT: bold"&gt;Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs &lt;/font&gt;In May 2011, the FASB issued guidance on fair value measurement and disclosure requirements. The guidance generally clarifies the application of existing requirements on topics including the concepts of highest and best use and valuation premise and disclosing quantitative information about the unobservable inputs used in the measurement of instruments categorized within Level&amp;#160;3 of the fair value hierarchy. Additionally, the guidance includes changes on topics such as measuring fair value of financial instruments that are managed within a portfolio and additional disclosure for fair value measurements categorized within Level&amp;#160;3 of the fair value hierarchy. This guidance is effective for the Company on January&amp;#160;1, 2012. The Company is evaluating the effects that adoption of this guidance will have.&lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;/div&gt;&lt;div style="TEXT-INDENT: 0pt; DISPLAY: block"&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;table style="FONT-FAMILY: times new roman; FONT-SIZE: 10pt" border="0" cellspacing="0" cellpadding="0" width="100%" align="center"&gt;&lt;tr valign="top"&gt;&lt;td style="WIDTH: 36pt"&gt;&lt;div&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;&amp;#160; &lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;td&gt;&lt;div align="left"&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;&lt;font style="FONT-STYLE: italic; DISPLAY: inline; FONT-WEIGHT: bold"&gt;Presentation of Comprehensive Income&lt;/font&gt; In June 2011, the FASB issued guidance on the presentation of comprehensive income. This guidance eliminates the option of presenting components of other comprehensive income as part of the statement of stockholders' equity. The guidance will allow the Company the option to present the total of comprehensive income, the components of net income and the components of other comprehensive income in either a single continuous statement of comprehensive income or in two separate but consecutive statements. This guidance is effective for the Company on January&amp;#160;1, 2012, and must be applied retrospectively. The Company is evaluating the effects of this guidance on disclosure, but it will not impact the Company's financial position, results of operations or cash flows.&lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;/div&gt;&lt;div style="TEXT-INDENT: 0pt; DISPLAY: block"&gt;&lt;br /&gt;&lt;/div&gt;</mdu:DescriptionOfNewAccountingPronouncementsTextBlock>

The Company anticipates the uncertainty about the timing of the deductibility will be resolved within the next 12&amp;#160;months.&lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;/div&gt;</us-gaap:IncomeTaxDisclosureTextBlock>

As of June&amp;#160;30, 2011, the Company had no outstanding foreign currency or interest rate hedges.

Cascade utilizes, and Intermountain periodically utilizes, natural gas swap agreements to manage a portion of their regulated natural gas supply portfolios in order to manage fluctuations in the price of natural gas related to core customers in accordance with authority granted by the IPUC, WUTC and OPUC. Core customers consist of residential, commercial and smaller industrial customers. The fair value of the derivative instrument must be estimated as of the end of each reporting period and is recorded on the Consolidated Balance Sheets as an asset or a liability. Periodic changes in the fair market value of the derivative instruments are recorded on the Consolidated Balance Sheets as a regulatory asset or a regulatory liability, and settlements of these arrangements are expected to be recovered through the purchased gas cost adjustment mechanism. Gains and losses on the settlements of these derivative instruments are recorded as a component of purchased natural gas sold on the Consolidated Statements of Income as they are recovered through the purchased gas cost adjustment mechanism. Under the terms of these arrangements, Cascade and Intermountain will either pay or receive settlement payments based on the difference between the fixed strike price and the monthly index price applicable to each contract. For the three and six months ended June&amp;#160;30, 2011, Cascade recorded the change in the fair market value of the derivative instruments of $1.9&amp;#160;million and $8.5&amp;#160;million, respectively, as a decrease to regulatory assets. For the three and six months ended June&amp;#160;30, 2010, Cascade and Intermountain recorded the change in the fair market value of the derivative instruments of $3.9&amp;#160;million and $9.0&amp;#160;million, respectively, as a decrease to regulatory assets.&lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;/div&gt;&lt;div style="TEXT-INDENT: 0pt; DISPLAY: block"&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;table style="FONT-FAMILY: times new roman; FONT-SIZE: 10pt" border="0" cellspacing="0" cellpadding="0" width="100%" align="center"&gt;&lt;tr valign="top"&gt;&lt;td style="WIDTH: 36pt"&gt;&lt;div&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;&amp;#160; &lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;td&gt;&lt;div align="left"&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;Certain of Cascade's derivative instruments contain credit-risk-related contingent features that permit the counterparties to require collateralization if Cascade's derivative liability positions exceed certain dollar thresholds. The dollar thresholds in certain of Cascade's agreements are determined and may fluctuate based on Cascade's credit rating on its debt. In addition, Cascade's derivative instruments contain cross-default provisions that state if the entity fails to make payment with respect to certain of its indebtedness, in excess of specified amounts, the counterparties could require early settlement or termination of such entity's derivative instruments in liability positions. The aggregate fair value of Cascade's derivative instruments with credit-risk-related contingent features that are in a liability position at June&amp;#160;30, 2011, was $900,000. The aggregate fair value of assets that would have been needed to settle the instruments immediately if the credit-risk-related contingent features were triggered on June&amp;#160;30, 2011, was $900,000.&lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;/div&gt;&lt;div style="TEXT-INDENT: 0pt; DISPLAY: block"&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;table style="FONT-FAMILY: times new roman; FONT-SIZE: 10pt" border="0" cellspacing="0" cellpadding="0" width="100%" align="center"&gt;&lt;tr valign="top"&gt;&lt;td style="WIDTH: 36pt"&gt;&lt;div&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;&amp;#160; &lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;td&gt;&lt;div align="left"&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;&lt;font style="DISPLAY: inline; TEXT-DECORATION: underline"&gt;Fidelity&lt;/font&gt;&lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;/div&gt;&lt;div&gt;&lt;table style="FONT-FAMILY: times new roman; FONT-SIZE: 10pt" border="0" cellspacing="0" cellpadding="0" width="100%" align="center"&gt;&lt;tr valign="top"&gt;&lt;td style="WIDTH: 36pt"&gt;&lt;div&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;&amp;#160; &lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;td&gt;&lt;div align="left"&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;At June&amp;#160;30, 2011, Fidelity held natural gas swap agreements with total forward notional volumes of 23.3&amp;#160;million MMBtu, natural gas basis swap agreements with total forward notional volumes of 12.9&amp;#160;million MMBtu, and oil swap, collar and put option agreements with total forward notional volumes of 3.7&amp;#160;million Bbl, all of which were designated as cash flow hedging instruments. At June&amp;#160;30, 2011, Fidelity held an oil call option agreement with total forward notional volumes of 184,000&amp;#160;Bbl, which did not qualify for hedge accounting. Fidelity utilizes these derivative instruments to manage a portion of the market risk associated with fluctuations in the price of natural gas and oil and basis differentials on its forecasted sales of natural gas and oil production.&lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;/div&gt;&lt;div style="TEXT-INDENT: 0pt; DISPLAY: block"&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;table style="FONT-FAMILY: times new roman; FONT-SIZE: 10pt" border="0" cellspacing="0" cellpadding="0" width="100%" align="center"&gt;&lt;tr valign="top"&gt;&lt;td style="WIDTH: 36pt"&gt;&lt;div&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;&amp;#160; &lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;td&gt;&lt;div align="left"&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;The fair value of the derivative instruments must be estimated as of the end of each reporting period and is recorded on the Consolidated Balance Sheets as an asset or liability. Changes in the fair value attributable to the effective portion of hedging instruments, net of tax, are recorded in stockholders' equity as a component of accumulated other comprehensive income (loss). At the date the natural gas and oil quantities are settled, the amounts accumulated in other comprehensive income (loss) are reported in the Consolidated Statements of Income. To the extent that the hedges are not effective, the ineffective portion of the changes in fair market value is recorded directly in earnings. The proceeds received for natural gas and oil production are generally based on market prices.&lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;/div&gt;&lt;div style="TEXT-INDENT: 0pt; DISPLAY: block"&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;table style="FONT-FAMILY: times new roman; FONT-SIZE: 10pt" border="0" cellspacing="0" cellpadding="0" width="100%" align="center"&gt;&lt;tr valign="top"&gt;&lt;td style="WIDTH: 36pt"&gt;&lt;div&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;&amp;#160; &lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;td&gt;&lt;div align="left"&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;The amount of hedge ineffectiveness was immaterial for the three and six months ended June&amp;#160;30, 2011, and 2010, and there were no components of the derivative instruments' gain or loss excluded from the assessment of hedge effectiveness. Gains and losses must be reclassified into earnings as a result of the discontinuance of cash flow hedges if it is probable that the original forecasted transactions will not occur. There were no such reclassifications into earnings as a result of the discontinuance of hedges. The gain on the derivative instrument that did not qualify for hedge accounting was reported in operating revenues on the Consolidated Statements of Income and was $1.9&amp;#160;million (before tax) and $179,000 (before tax) for the three and six months ended June&amp;#160;30, 2011, respectively.&lt;/font&gt;&lt;/div&gt;&lt;div align="left"&gt;&amp;#160;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;/div&gt;&lt;div&gt;&lt;table style="FONT-FAMILY: times new roman; FONT-SIZE: 10pt" border="0" cellspacing="0" cellpadding="0" width="100%" align="center"&gt;&lt;tr valign="top"&gt;&lt;td style="WIDTH: 36pt"&gt;&lt;div&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;&amp;#160; &lt;/font&gt;&lt;/div&gt;&lt;/td&gt;&lt;td&gt;&lt;div align="left"&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;Gains and losses on derivative instruments that are reclassified from accumulated other comprehensive income (loss) to current-period earnings are included in operating revenues on the Consolidated Statements of Income.

Interim financial statements do not include all disclosures provided in annual financial statements and, accordingly, these financial statements should be read in conjunction with those appearing in the 2010 Annual Report. The information is unaudited but includes all adjustments that are, in the opinion of management, necessary for a fair presentation of the accompanying consolidated interim financial statements and are of a normal recurring nature. Depreciation, depletion and amortization expense is reported separately on the Consolidated Statements of Income and therefore is excluded from the other line items within operating expenses.
