OTTER TAIL CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(not audited)

In the opinion of management, Otter Tail Corporation (the Company) has included all adjustments (including normal recurring accruals) necessary for a fair presentation of the consolidated financial statements for the periods presented. The consolidated financial statements and notes thereto should be read in conjunction with the consolidated financial statements and notes as of and for the years ended December 31, 2010, 2009 and 2008 included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2010. Because of seasonal and other factors, the earnings for the three month and six month periods ended June 30, 2011 should not be taken as an indication of earnings for all or any part of the balance of the year.

The following notes are numbered to correspond to numbers of the notes included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2010.

1. Summary of Significant Accounting Policies

Revenue Recognition

Due to the diverse business operations of the Company, revenue recognition depends on the product produced and sold or service performed. The Company recognizes revenue when the earnings process is complete, evidenced by an agreement with the customer, there has been delivery and acceptance, and the price is fixed or determinable. In cases where significant obligations remain after delivery, revenue recognition is deferred until such obligations are fulfilled. Provisions for sales returns and warranty costs are recorded at the time of the sale based on historical information and current trends. In the case of derivative instruments, such as Otter Tail Power Company’s (OTP) forward energy contracts, marked-to-market and realized gains and losses are recognized on a net basis in revenue in accordance with Accounting Standards Codification (ASC) 815-10-45-9. Gains and losses on forward energy contracts subject to regulatory treatment, if any, are deferred and recognized on a net basis in revenue in the period realized.

For the Company’s operating companies recognizing revenue on certain products when shipped, those operating companies have no further obligation to provide services related to such product. The shipping terms used in these instances are FOB shipping point.

Some of the operating businesses in the Company’s Wind Energy, Manufacturing and Construction segments enter into fixed-price construction contracts. Revenues under these contracts are recognized on a percentage-of-completion basis. The method used to determine the progress of completion is based on the ratio of labor hours incurred to total estimated labor hours at the Company’s wind tower manufacturer and costs incurred to total estimated costs on all other construction projects. If a loss is indicated at a point in time during a contract, a projected loss for the entire contract is estimated and recognized. Following are the percentages of the Company’s consolidated revenues recorded under the percentage-of-completion method:

	Three Months Ended						Six Months Ended
	June 30,						June 30,
	2011			2010			2011			2010
Percentage-of-Completion Revenues		33.9	%		27.6	%		32.8	%		26.7	%

The following table summarizes costs incurred and billings and estimated earnings recognized on uncompleted contracts:

	June 30,			December 31,
(in thousands)	2011			2010
Costs Incurred on Uncompleted Contracts	$	464,849		$	460,125

Plus Estimated Earnings Recognized		22,085			31,231
Net Costs Incurred in Excess of Billings and Accrued Revenues on Uncompleted Contracts	$	68,814		$	60,885

The following amounts are included in the Company’s consolidated balance sheets. Billings in excess of costs and estimated earnings on uncompleted contracts are included in Accounts Payable:

	June 30,			December 31,
(in thousands)	2011			2010
Costs and Estimated Earnings in Excess of Billings	$	71,688		$	67,352

These amounts are related to costs incurred on wind towers in the process of completion on major contracts under which the customer is not billed until towers are completed and ready for shipment.

Warranty Reserves

The Company establishes reserves for estimated product warranty costs at the time revenue is recognized based on historical warranty experience and additionally for any known product warranty issues. Certain Company products carry one to fifteen year warranties. The warranty reserve balance was $2,956,000 as of June 30, 2011. Although the Company engages in extensive product quality programs and processes, the Company’s warranty obligations have been and may in the future be affected by product failure rates, repair or field replacement costs and additional development costs incurred in correcting product failures.

Expenses associated with remediation activities in the Wind Energy segment could be substantial. The potential exists for multiple claims based on one defect repeated throughout the production process or for claims where the cost to repair or replace the defective part is highly disproportionate to the original cost of the part. If the Company is required to cover remediation expenses in addition to regular warranty coverage, the Company could be required to accrue additional expenses and experience additional unplanned cash expenditures which could adversely affect the Company’s consolidated results of operations and financial condition.

Retainage

Accounts Receivable include the following amounts, billed under contracts by the Company’s subsidiaries, that have been retained by customers pending project completion:

Fair Value Measurements

The Company follows ASC 820, Fair Value Measurements and Disclosures, for recurring fair value measurements. ASC 820 provides a single definition of fair value and requires enhanced disclosures about assets and liabilities measured at fair value. ASC 820-10-35 establishes a hierarchal framework for disclosing the observability of the inputs utilized in measuring assets and liabilities at fair value. The three levels defined by the hierarchy and examples of each level are as follows:

Level 1 – Quoted prices are available in active markets for identical assets or liabilities as of the reported date. The types of assets and liabilities included in Level 1 are highly liquid and actively traded instruments with quoted prices, such as equities listed by the New York Stock Exchange and commodity derivative contracts listed on the New York Mercantile Exchange.

Level 2 – Pricing inputs are other than quoted prices in active markets, but are either directly or indirectly observable as of the reported date. The types of assets and liabilities included in Level 2 are typically either comparable to actively traded securities or contracts, such as treasury securities with pricing interpolated from recent trades of similar securities, or priced with models using highly observable inputs, such as commodity options priced using observable forward prices and volatilities.

Level 3 – Significant inputs to pricing have little or no observability as of the reporting date. The types of assets and liabilities included in Level 3 are those with inputs requiring significant management judgment or estimation and may include complex and subjective models and forecasts.

The following table presents, for each of these hierarchy levels, the Company’s assets and liabilities that are measured at fair value on a recurring basis as of June 30, 2011 and December 31, 2010:

Reclassifications and Changes to Presentation

The Company’s consolidated balance sheet as of December 31, 2010, and consolidated income statement and consolidated statement of cash flows for the three and six months ended June 30, 2010 reflect the reclassifications of the assets and liabilities, operating results and cash flows of Idaho Pacific Holdings, Inc. (IPH) and E.W. Wylie’s (Wylie) heavy haul and specialized shipment and transportation of wind turbine components business to discontinued operations as a result of second quarter 2011 decisions to sell IPH and to exit the heavy haul and specialized shipment and transportation of wind turbine components business. The Company reached an agreement to sell IPH on May 6, 2011. The reclassifications had no impact on the Company’s total assets, consolidated net income or cash flows for the three and six months ended June 30, 2010.

In 2011 management reported Minnesota Conservation Improvement Program (MNCIP) incentives in Operating Revenues – Electric rather than Other Income as they had been classified prior to 2011. The Company has corrected this classification resulting in the following increases in Operating Revenues and Operating Income and decreases in Other Income:

	Three Months Ended		Six Months Ended
(in thousands)	June 30, 2010		June 30, 2010
MNCIP Incentives reclassified from Other Income to Operating Revenue	$	1,239	$	1,601

The correction had no impact on the Company’s net income, total assets, or operating cash flows for the three and six months ended June 30, 2010.

2. Segment Information

The Company's businesses have been classified into six segments to be consistent with its business strategy and the reporting and review process used by the Company’s chief operating decision makers. These businesses reach customers in all 50 states and international markets. The six segments are: Electric, Wind Energy, Manufacturing, Construction, Plastics and Health Services.

Electric includes the production, transmission, distribution and sale of electric energy in Minnesota, North Dakota and South Dakota by OTP. In addition, OTP is an active wholesale participant in the Midwest Independent Transmission System Operator (MISO) markets. OTP’s operations have been the Company’s primary business since 1907. Additionally, the electric segment includes Otter Tail Energy Services Company (OTESCO), which provides technical and engineering services, wind farm site development and energy efficient lighting primarily in North Dakota and Minnesota.

Wind Energy consists of two businesses: a steel fabrication company primarily involved in the production of wind towers sold in the United States and Canada, with manufacturing facilities in North Dakota, Oklahoma and Ontario, Canada, and a trucking company headquartered in West Fargo, North Dakota, specializing in flatbed services and operating in 49 states and six Canadian provinces. Prior to the realignment of the Company’s business segments, the wind tower production company was included in Manufacturing and the trucking company was included in Other Business Operations.

Manufacturing consists of businesses in the following manufacturing activities: contract machining, metal parts stamping and fabrication, and production of waterfront equipment, material and handling trays and horticultural containers. These businesses have manufacturing facilities in Florida, Illinois, Minnesota and Missouri and sell products primarily in the United States.

Construction consists of businesses involved in residential, commercial and industrial electric contracting and construction of fiber optic and electric distribution systems, water, wastewater and HVAC systems primarily in the central United States. Construction operations were included in Other Business Operations prior to the realignment of the Company’s business segments.

Plastics consists of businesses producing polyvinyl chloride (PVC) pipe in the upper Midwest and Southwest regions of the United States.

Health Services consists of businesses involved in the sale of diagnostic medical equipment, patient monitoring equipment and related supplies and accessories. These businesses also provide equipment maintenance, diagnostic imaging equipment and technical staff to various medical institutions located throughout the United States.

Food Ingredient Processing is no longer a reportable segment as a result of the sale of IPH on May 6, 2011. The results of operations, financial position and cash flows of IPH are reported as discontinued operations in the Company’s consolidated financial statements.

OTP and OTESCO are wholly owned subsidiaries of the Company. All of the Company’s other businesses are owned by its wholly owned subsidiary, Varistar Corporation (Varistar).

Corporate includes items such as corporate staff and overhead costs, the results of the Company’s captive insurance company and other items excluded from the measurement of operating segment performance. Corporate assets consist primarily of cash, prepaid expenses, investments and fixed assets. Corporate is not an operating segment. Rather, it is added to operating segment totals to reconcile to totals on the Company’s consolidated financial statements.

The Company had no single external customer that accounted for 10% or more of the Company’s consolidated revenues in 2010. One customer of DMI has accounted for 11.7% of the Company’s consolidated revenues in the first six months of 2011. Substantially all of the Company’s long-lived assets are within the United States except for a wind tower manufacturing plant in Fort Erie, Ontario, Canada.

The following table presents the percent of consolidated sales revenue by country:

	Three Months Ended						Six Months Ended
	June 30,						June 30,

3. Rate and Regulatory Matters

Minnesota

2010 General Rate Case Filing —OTP filed a general rate case on April 2, 2010 requesting an 8.01% base rate increase with a 3.8% interim rate increase request. On May 27, 2010, the Minnesota Public Utilities Commission (MPUC) issued an order accepting the filing, suspending rates, and approving an interim rate increase of 3.8% to be effective with customer usage on and after June 1, 2010. The MPUC held a hearing to decide on the issues in the rate case on March 25, 2011 and issued a written order on April 25, 2011. The MPUC authorized a revenue increase of approximately $5.0 million, or 3.76% in base rate revenues, excluding the effect of moving recovery of wind investments to base rates. The MPUC’s written order included: (1) recovery of Big Stone II costs over five years (see discussion below), (2) moving recovery of wind farm assets from rider recovery to base rate recovery, (3) transfer of a portion of MNCIP costs from rider recovery to base rate recovery, (4) transfer of the investment in two transmission lines from rider recovery to base rate recovery, and (5) changing the mechanism for providing customers with a credit for margins earned on asset-based wholesale sales of electricity from a credit to base rates to a credit to the Minnesota fuel clause adjustment (FCA). When these changes to recovery mechanisms are taken into account, the overall increase to customers will be approximately 1.6% compared to the authorized interim rate increase of 3.8%, which will result in an interim rate refund of approximately $3.9 million. OTP accrued a $2.3 million refund liability in the first quarter of 2011 and an additional $1.2 million in the second quarter of 2011 for revenue billed under interim rates from June 1, 2010 through June 30, 2011. OTP expects the refund to be distributed to Minnesota customers during the fourth quarter of 2011. Pursuant to the order, OTP’s allowed rate of return on rate base will increase from 8.33% to 8.61% and its allowed rate of return on equity will increase from 10.43% to 10.74%. OTP's rates of return will be based on a capital structure of 48.28% long term debt and 51.72% common equity. On May 16, 2011, OTP requested that the MPUC reconsider its decisions on test year pension costs, the impact of accumulated pension contributions, a sales adjustment, and clarification of the expenses related to pension and other benefits . The MPUC denied all of OTP’s petitions for reconsideration and clarification on June 23, 2011. Final rates are anticipated to become effective October 1, 2011.

OTP has a regulatory asset of $4.1 million for revenues that are eligible for recovery through the Minnesota Renewable Resource Adjustment (MNRRA) rider that have not been billed to Minnesota customers as of June 30, 2011. Except for the balance of this regulatory asset and any amount necessary to true-up amounts undercollected while the current MNRRA rider rate has been in effect, the recovery of MNRRA costs will be moved to base rates in October 2011 under the MPUC’s April 25, 2011 general rate case order.

In its April 25, 2011 general rate case order, the MPUC approved the transfer of transmission costs currently being recovered through OTP’s Minnesota Transmission Cost Recovery (TCR) rider to recovery in base rates. The transmission investments for two projects currently in the TCR will continue to be recovered through OTP’s Minnesota TCR rider until final rates go into effect in October 2011. OTP filed a request for an update to its Minnesota TCR rider on October 5, 2010. Comments and reply comments have been filed but the MPUC has not yet scheduled a hearing on the request.

North Dakota

Transmission Cost Recovery Rider —North Dakota law provides a mechanism for automatic adjustment outside of a general rate proceeding to recover jurisdictional capital and operating costs incurred by a public utility for new or modified electric transmission facilities. OTP requested recovery of such costs in its general rate case filed in November 2008 and was granted recovery of such costs by the North Dakota Public Service Commission (NDPSC) in its November 25, 2009 order. OTP filed a request for an initial North Dakota TCR rider with the NDPSC on April 29, 2011.

South Dakota

2010 General Rate Case Filing —On August 20, 2010 OTP filed a general rate case with the South Dakota Public Utilities Commission (SDPUC) requesting an overall revenue increase of approximately $2.8 million, or just under 10.0%, which includes, among other things, recovery of investments and expenses related to renewable resources. On September 28, 2010 the SDPUC suspended OTP’s proposed rates for a period of 180 days to allow time to review OTP’s proposal. On January 19, 2011 OTP submitted a proposal to use current rate design to implement an interim rate in South Dakota to be effective on and after February 17, 2011. On January 26, 2011 OTP submitted an amended proposal to also use a lower interim rate increase than originally proposed. At its February 1, 2011 meeting, the SDPUC approved OTP’s request to implement interim rates using current rate design and the lower interim increase to be effective on and after February 17, 2011. On April 21, 2011, the SDPUC issued its written order approving a revenue increase of approximately $643,000 with an overall rate of return on rate base of 8.50%. Final rates went into effect on June 1, 2011.

Transmission Cost Recovery Rider —South Dakota law provides a mechanism for automatic adjustment outside of a general rate proceeding to recover jurisdictional capital and operating costs incurred by a public utility for new or modified electric transmission facilities. OTP submitted a request for an initial South Dakota TCR rider to the SDPUC on November 5, 2010. The South Dakota TCR request is expected to be on the SDPUC agenda in fall 2011.

Capacity Expansion 2020 (CapX2020)

CapX2020 is a joint initiative of 11 investor-owned, cooperative, and municipal utilities in Minnesota and the surrounding region to upgrade and expand the electric transmission grid to ensure continued reliable and affordable service. The CapX2020 companies identified four major transmission projects for the region: (1) the Fargo–Monticello 345 kiloVolt (kV) Project (the Fargo Project), (2) the Brookings–Southeast Twin Cities 345 kV Project (the Brookings Project), (3) the Bemidji – Grand Rapids Project (the Bemidji Project), and (4) the Twin Cities–LaCrosse 345 kV Project. OTP is an investor in the Fargo Project, the Brookings Project and the Bemidji Project.

On April 16, 2009 the MPUC approved Certificates of Need (CONs) for the three 345 kV Group 1 CapX2020 line projects: the Fargo Project, the Brookings Project and the Twin Cities–LaCrosse 345 kV Project.

The Fargo Project —The route permit application for the Monticello to St. Cloud portion of the Fargo Project was filed in April 2009. The MPUC approved the route permit application and issued a written order on July 12, 2010. Required permits from the Minnesota Department of Transportation, Minnesota Department of Natural Resources and the U.S. Army Corps of Engineers were received in 2010. A Transmission Capacity Exchange Agreement, allocating transmission capacity rights to owners across the Monticello to St. Cloud portion of the Fargo Project, was accepted by the Federal Energy Regulatory Commission (FERC) in the third quarter of 2010. The Monticello to St. Cloud portion of the Fargo Project is scheduled for completion in December 2011.

The Minnesota route permit application for the St. Cloud to Fargo portion of the Fargo Project was filed on October 1, 2009. Minnesota State Environmental Impact Statement (EIS) scoping meetings were held in September 2010 and public hearings were held in November 2010.The MPUC approved the route permit on June 24, 2011. Construction is expected to begin in the fall of 2011 on the line section between St. Cloud and Alexandria, Minnesota.

On October 8, 2010, OTP submitted its application for a Certificate of Public Convenience and Necessity (CPCN) from the NDPSC for the North Dakota portion of the Fargo Project. The NDPSC approved the CPCN in January 2011. The application for the North Dakota Certificate of Corridor Compatibility (CCC) was filed on December 30, 2010 and was revised in March 2011. The June 23, 2011 hearing for the North Dakota CCC application was postponed. It is expected that a route permit application will be filed with the NDPSC in the third quarter of 2011. Due to the postponement of the CCC hearing, the NDPSC will conduct a joint process going forward pertaining to the CCC and North Dakota route permit applications.

The Brookings Project —The Minnesota route permit application for the Brookings Project was filed in the fourth quarter of 2008. The MPUC approved the final line segment route permit for the Brookings Project on February 3, 2011.

An application for a South Dakota facility route permit was filed with the SDPUC on November 22, 2010. The SDPUC conducted a public hearing in January 2011 and the South Dakota route permit was approved in June 2011. The MISO board of directors granted conditional approval of the Multi-Value Project (MVP) cost allocation designation under the MISO Tariff for the Brookings Project. Once the MISO board finalizes its analysis of all of the MVP projects in its study portfolio, the MISO board will be in a position to remove the condition, which is anticipated to occur in December 2011.

The Bemidji Project —OTP serves as the lead utility for the Bemidji Project, which has an expected in-service date in late 2012. The MPUC approved the CON for this project on July 9, 2009. A route permit application was filed with the MPUC in the second quarter of 2008 and approved on October 28, 2010. The joint state and federal EIS was published by federal agencies on September 7, 2010, and the project’s Transmission Capacity Exchange Agreement was accepted and approved by the FERC in the third quarter of 2010. On March 25, 2011, the Leech Lake Band of Ojibwe (LLBO) submitted a petition to the MPUC, requesting the revocation or suspension of the project’s route permit. The request is based on the LLBO’s allegation that it has jurisdiction to require the project to obtain its permission to cross through the historical boundaries of the Leech Lake Reservation. The owners of the Bemidji Project , including OTP, filed reply comments in opposition to the LLBO’s request. On April 25, 2011, the Bemidji Project owners filed a declaratory judgment in the U.S. District Court for Minnesota against the LLBO seeking that no consent from the LLBO is required for the project to run through the LLBO reservation boundaries since the project is located exclusively on non LLBO lands. On June 22, 2011, Federal District Judge Frank issued a preliminary injunction which ordered the LLBO to cease and desist from pursuing its claims of jurisdiction over the project in tribal court or the MPUC or from taking any other actions to interfere with the routing or construction of the project . The parties have engaged in mediated settlement discussions with the federal magistrate judge . The LLBO’s motion to dismiss the declaratory judgment action is currently scheduled to be heard on September 16, 2011.

CapX2020 Request for Advance Determination of Prudence —On October 5, 2009 OTP filed an application for an advance determination of prudence with the NDPSC for its proposed participation in three of the four Group 1 projects: the Fargo Project, the Brookings Project and the Bemidji Project. An administrative law judge conducted an evidentiary hearing on the application in May 2010. On October 6, 2010 the NDPSC adopted an order approving a settlement between OTP and intervener NDPSC advocacy staff, and issued an advance determination of prudence to OTP for participation in the three Group 1 projects. The order is subject to a number of terms and conditions in addition to the settlement agreement, including the provision of additional information on the eventual resolution of cost allocation issues relevant to the Brookings Project and its associated impact on North Dakota. On April 29, 2011, OTP filed its compliance filing with the NDPSC, seeking a determination of continued prudence for OTP’s investment in the Brookings Project. The NDPSC hearing occurred on July 25, 2011 and the NDPSC scheduled a working session for August 5, 2011 to discuss the matter.

Big Stone Air Quality Control System

The South Dakota Department of Environment and Natural Resources (DENR) determined that the Big Stone Plant is subject to Best Available Retrofit Technology (BART) requirements of the Clean Air Act (CAA), based on air dispersion modeling indicating that Big Stone’s emissions reasonably contribute to visibility impairment in national parks and wilderness areas in Minnesota, North Dakota, South Dakota and Michigan. Under the U.S. Environmental Protection Agency’s (EPA) regional haze regulations, South Dakota developed and submitted its implementation plan and associated implementation rules to the EPA on January 21, 2011. Under the South Dakota Implementation Plan, and its implementing rules that became effective in December 2010, the Big Stone Plant must install and operate a new BART compliant air quality control system to reduce emissions as expeditiously as practicable, but no later than five years after the EPA’s approval of South Dakota’s implementation plan. Although studies and evaluations are continuing, the current project cost is estimated to be approximately $490 million (OTP’s share would be $264 million). On January 14, 2011 OTP filed a petition asking the MPUC for advance determination of prudence (ADP) for the design, construction and operation of the BART compliant air quality control system at Big Stone Plant attributable to serving OTP’s Minnesota customers. On June 1, 2011, the MPUC referred the matter to the Office of Administrative Hearings for contested case proceedings before an administrative law judge (ALJ). On June 17, 2011, the ALJ entered a scheduling order that calls for evidentiary hearings from August 17-19, 2011, with an ALJ report and recommendation by September 30, 2011. Because of the Minnesota government shutdown in July 2011, these dates have changed to a hearing date of September 14-16, 2011 with an ALJ report by November 4, 2011 . OTP filed an application for an ADP with the NDPSC on May 20, 2011 with a decision expected by December 20, 2011. The Big Stone Plant is currently operating within all presently applicable federal and state air quality and emission standards.

Big Stone II Project

On June 30, 2005 OTP and a coalition of six other electric providers entered into several agreements for the development of a second electric generating unit, named Big Stone II, at the site of the existing Big Stone Plant near Milbank, South Dakota. On September 11, 2009 OTP announced its withdrawal—both as a participating utility and as the project’s lead developer—from Big Stone II, due to a number of factors. On November 2, 2009, the remaining Big Stone II participants announced the cancellation of the Big Stone II project.

OTP requested recovery of the Minnesota portion of its Big Stone II development costs over a five-year period as part of its general rate case filed in Minnesota on April 2, 2010. In a written order issued on April 25, 2011, the MPUC authorized recovery of the Minnesota portion of Big Stone II generation development costs from Minnesota ratepayers over a 60-month recovery period expected to begin in October 2011. The amount of Big Stone II generation costs incurred by OTP that were deemed recoverable from Minnesota ratepayers was $3,199,000 (which excludes $3,246,000 of project transmission-related costs). Because the MPUC denied OTP an investment return on these deferred costs over the 60-month recovery period, the recoverable amount has been discounted to its present value of $2,758,000, in accordance with ASC 980, Regulated Operations , accounting requirements.

On December 30, 2010 OTP filed a request for an extension of the Minnesota Route Permit for the Big Stone transmission facilities. The request asks to extend the deadline for filing a CON for these transmission facilities until March 17, 2013. The April 25, 2011 MPUC order instructed OTP to transfer the $3,246,000 Minnesota share of Big Stone II transmission costs to Construction Work in Progress (CWIP) and to create a tracker account through which any over or under recoveries could be accumulated for refund or recovery determination in future rate cases as a regulatory liability or asset. If determined eligible for recovery under the FERC-approved MISO regional transmission tariff, the Minnesota portion of Big Stone II transmission costs and accumulated Allowance for Funds Used During Construction (AFUDC) will receive rate base treatment and recovery through the FERC-approved MISO regional transmission rates. Any amounts over or under collected through MISO rates will be reflected in the tracker account.

OTP requested recovery of the South Dakota portion of its Big Stone II development costs over a five-year period as part of its general rate case filed in South Dakota on August 20, 2010. In the first quarter of 2011, the SDPUC approved recovery of the South Dakota portion of Big Stone II generation development costs totaling approximately $1.0 million from South Dakota ratepayers over a ten-year period beginning in February 2011 with the implementation of interim rates. OTP will be allowed to earn a return on the amount subject to recovery over the ten-year recovery period. Therefore, the South Dakota settlement amount is not discounted. OTP transferred the remaining Big Stone II transmission costs to CWIP, with such costs subject to AFUDC and recovery in future FERC-approved MISO rates or retail rates.

4. Regulatory Assets and Liabilities

As a regulated entity, OTP accounts for the financial effects of regulation in accordance with ASC 980, Regulated Operations . This accounting standard allows for the recording of a regulatory asset or liability for costs that will be collected or refunded in the future as required under regulation. The following table indicates the amount of regulatory assets and liabilities recorded on the Company’s consolidated balance sheet:


(in thousands)	June 30, 2011		December 31, 2010		Remaining Recovery/ Refund Period

Total Regulatory Liabilities	$	68,275	$	66,416
Net Regulatory Asset Position	$	46,764	$	63,737

The regulatory asset related to the unrecognized transition obligation, prior service costs and actuarial losses on pensions and other postretirement benefits represents benefit costs and actuarial losses subject to recovery through rates as they are expensed over the remaining service lives of active employees included in the plans. These unrecognized benefit costs and actuarial losses are required to be recognized as components of Accumulated Other Comprehensive Income in equity under ASC 715, Compensation—Retirement Benefits, but are eligible for treatment as regulatory assets based on their probable recovery in future retail electric rates.

All Deferred Marked-to-Market Gains and Losses recorded as of June 30, 2011 are related to forward purchases of energy scheduled for delivery through August 2015.

Deferred Conservation Program Costs & Accrued Incentives represent mandated conservation expenditures and incentives recoverable through retail electric rates.

Minnesota Renewable Resource Rider Accrued Revenues relate to revenues earned on qualifying 2008 through 2011 renewable resource costs incurred to serve Minnesota customers that have not been billed to Minnesota customers as of June 30, 2011.

Big Stone II Unrecovered Project Costs – North Dakota are the North Dakota share of costs incurred by OTP related to its participation in the abandoned Big Stone II generation project.

Big Stone II Unrecovered Project Costs – Minnesota are the Minnesota share of costs incurred by OTP related to its participation in the abandoned Big Stone II generation project.

Debt Reacquisition Premiums are being recovered from OTP customers over the remaining original lives of the reacquired debt issues, the longest of which is 255 months.

The Accumulated Asset Retirement Obligation (ARO) Accretion/Depreciation Adjustment will accrete and be amortized over the lives of property with asset retirement obligations.

The regulatory assets and liabilities related to Deferred Income Taxes result from changes in statutory tax rates accounted for in accordance with ASC 740, Income Taxes .

North Dakota Renewable Resource Rider Accrued Revenues relate to revenues earned on qualifying renewable resource costs incurred to serve North Dakota customers that have not been billed to North Dakota customers as of June 30, 2011.

Big Stone II Unrecovered Project Costs – South Dakota are the South Dakota share of costs incurred by OTP related to its participation in the abandoned Big Stone II generation project.

South Dakota – Asset-Based Margin Sharing Shortfall represents differences in OTP’s South Dakota share of actual profit margins on wholesale sales of electricity from company-owned generating units and estimated profit margins from those sales that were used in determining current South Dakota retail electric rates. Net asset-based margin sharing accumulated shortfalls will be subject to recovery or refund through future retail rate adjustments in South Dakota.

Minnesota Transmission Rider Accrued Revenues are expected to be recovered from Minnesota retail electric customers over 12 months beginning in January 2012.

The Accumulated Reserve for Estimated Removal Costs – Net of Salvage is reduced as actual removal costs, net of salvage revenues, are incurred.

No schedule has been set for the return of the June 30, 2011 Minnesota Transmission Rider Accrued Refund balance.

South Dakota – Nonasset-Based Margin Sharing Excess represents 25% of OTP’s South Dakota share of actual profit margins on nonasset-based wholesale sales of electricity. The excess margins accumulated annually will be subject to refund through future retail rate adjustments in South Dakota in the following year.

If for any reason, OTP ceases to meet the criteria for application of guidance under ASC 980 for all or part of its operations, the regulatory assets and liabilities that no longer meet such criteria would be removed from the consolidated balance sheet and included in the consolidated statement of income as an extraordinary expense or income item in the period in which the application of guidance under ASC 980 ceases.

5. Forward Contracts Classified as Derivatives

Electricity Contracts

All of OTP’s wholesale purchases and sales of energy under forward contracts that do not meet the definition of capacity contracts are considered derivatives subject to mark-to-market accounting. OTP’s objective in entering into forward contracts for the purchase and sale of energy is to optimize the use of its generating and transmission facilities and leverage its knowledge of wholesale energy markets in the region to maximize financial returns for the benefit of both its customers and shareholders. OTP’s intent in entering into certain of these contracts is to settle them through the physical delivery of energy when physically possible and economically feasible. OTP also enters into certain contracts for trading purposes with the intent to profit from fluctuations in market prices through the timing of purchases and sales.

The market prices used to value OTP’s forward contracts for the purchases and sales of electricity and electricity generating capacity are determined by survey of counterparties or brokers used by OTP’s power services’ personnel responsible for contract pricing, as well as prices gathered from daily settlement prices published by the Intercontinental Exchange and CME Globex. For certain contracts, prices at illiquid trading points are based on a basis spread between that trading point and more liquid trading hub prices. These basis spreads are determined based on available market price information and the use of forward price curve models. The fair value measurements of these forward energy contracts fall into level 2 of the fair value hierarchy set forth in ASC 820-10-35.

The following tables show the effect of marking to market forward contracts for the purchase and sale of electricity and the location and fair value amounts of the related derivatives reported on the Company’s consolidated balance sheets as of June 30, 2011 and December 31, 2010, and the change in the Company’s consolidated balance sheet position from December 31, 2010 to June 30, 2011:

Net Credit Risk on Forward Energy Contracts	$	1,732		4	$	1,129		4
Net Credit Risk to Single Largest Counterparty	$	970			$	585

OTP had no exposure at June 30, 2011 or December 31, 2010 to counterparties with credit ratings below investment grade. Counterparties with investment grade credit ratings have minimum credit ratings of BBB- (Standard & Poor’s), Baa3 (Moody’s) or BBB- (Fitch). The credit risk exposures include net amounts due to OTP on receivables/payables from completed transactions billed and unbilled plus marked-to-market gains/losses on forward contracts for the purchase and sale of electricity scheduled for delivery subsequent to the reporting date. Individual counterparty exposures are offset according to legally enforceable netting arrangements.

The following table provides a breakdown of OTP’s credit risk standing on forward energy contracts in a marked-to-market loss positions as of June 30, 2011 and December 31, 2010:

6. Common Shares and Earnings Per Share

Common Shares

Following is a reconciliation of the Company’s common shares outstanding from December 31, 2010 through June 30, 2011:

Common Shares Outstanding, December 31, 2010	36,002,739
Issuances:
Restricted Stock Issued to Employees	24,600
Restricted Stock Issued to Nonemployee Directors	24,000
Vesting of Restricted Stock Units	16,475
Retirements:
Shares Withheld for Individual Income Tax Requirements	(6,641	)
Common Shares Outstanding, June 30, 2011	36,061,173

Earnings Per Share

Basic earnings per common share are calculated by dividing earnings available for common shares by the weighted average number of common shares outstanding during the period. Diluted earnings per common share are calculated by adjusting outstanding shares, assuming conversion of all potentially dilutive stock options. Stock options with exercise prices greater than the market price are excluded from the calculation of diluted earnings per common share. Nonvested restricted shares granted to the Company’s directors and employees are considered dilutive for the purpose of calculating diluted earnings per share but are considered contingently returnable and not outstanding for the purpose of calculating basic earnings per share. Underlying shares related to nonvested restricted stock units granted to employees are considered dilutive for the purpose of calculating diluted earnings per share. Shares expected to be awarded for stock performance awards granted to executive officers are considered dilutive for the purpose of calculating diluted earnings per share.

Excluded from the calculation of diluted earnings per share are the following outstanding stock options which had exercise prices greater than the average market prices:

Three Months Ended June 30,	Options Outstanding	Range of Exercise Prices
2011	172,460	$24.93 – $31.34
2010	388,960	$24.93 – $31.34

Six Months Ended June 30,	Options Outstanding	Range of Exercise Prices
2011	172,460	$24.93 – $31.34
2010	388,960	$24.93 – $31.34

7. Share-Based Payments

The Company has five share-based payment programs.

Stock Incentive Awards

On April 11, 2011 the Company’s Board of Directors granted the following stock incentive awards to the Company’s non-employee directors, executive officers and key employees under the 1999 Stock Incentive Plan, as amended:

Award	Shares/Units Granted		Grant-Date Fair Value per Share		Vesting
Restricted Stock Granted to Nonemployee Directors		24,000	$	22.51	25% per year through April 8, 2015
Restricted Stock Granted to Executive Officers		24,600	$	22.51	25% per year through April 8, 2015
Stock Performance Awards Granted to Executive Officers		48,600	$	23.61	December 31, 2013
Restricted Stock Units Granted to Employees		19,800	$	18.03	100% on April 8, 2015

The restricted shares granted to the Company’s nonemployee directors and executive officers (which includes OTP’s president) are eligible for full dividend and voting rights. The grant date fair value of each share of restricted stock was the average of the high and low market price per share on the date of grant.

Under the performance share awards, the Company’s executive officers could earn up to an aggregate of 97,200 common shares based on the Company’s total shareholder return relative to the total shareholder return of the companies that comprise the Edison Electric Institute Index over the performance measurement period of January 1, 2011 through December 31, 2013. The aggregate target share award is 48,600 shares. Actual payment may range from zero to 200% of the target amount. The executive officers have no voting or dividend rights related to these shares until the shares, if any, are issued at the end of the performance period. The grant date fair value of the target amount of common shares projected to be awarded was determined under a Monte Carlo simulation valuation method. The terms of these awards are such that the entire award will be classified and accounted for as a liability, as required under ASC 718-10-25-18, and will be measured over the performance period based on the fair value of the award at the end of each reporting period subsequent to the grant date.

The grant date fair value of each restricted stock unit was based on the market value of one share of the Company’s common stock on the grant date, discounted for the value of the dividend exclusion over the four-year vesting period.

As of June 30, 2011 the remaining unrecognized compensation expense related to stock-based compensation was approximately $3.2 million (before income taxes) which will be amortized over a weighted-average period of 2.8 years.

Compensation expense recognized under the Company’s stock-based payment programs:

	Three Months Ended					Six Months Ended

9. Commitments and Contingencies

Electric Utility Capacity and Energy Requirements and Coal and Delivery Contracts

In the first quarter of 2011, OTP entered into additional energy purchase agreements increasing its commitments for capacity and energy requirements. Amounts of commitments for OTP’s capacity and energy requirements under agreements extending through 2032 were as follows:

Capacity and Energy Requirements (thousands)	June 30, 2011		December 31, 2010		Increase
2011	$	21,268	$	20,134	$	1,134
2012		25,025		21,637		3,388
2013		21,868		16,492		5,376
2014		24,701		15,388		9,313
2015		18,915		12,307		6,608
Beyond 2015		78,879		78,879		--
Total	$	190,656	$	164,837	$	25,819

OTP has contracts providing for the purchase and delivery of a significant portion of its current coal requirements. In the first half of 2011, OTP extended its contract for the purchase of coal for Hoot Lake Plant resulting in an increase in minimum purchase commitments. OTP’s current coal purchase agreements under contracts expire in 2012 and 2016. OTP is now committed to the minimum purchase, dating from January 1, 2011, or to make payments in lieu thereof in the following amounts:

Coal and Freight Purchase Commitments (thousands)	June 30, 2011		December 31, 2010		Increase
2011	$	52,819	$	47,122	$	5,697
2012		48,692		34,958		13,734
2013		9,855		9,855		--
2014		9,854		9,854		--
2015		9,854		9,854		--
Beyond 2015		4,106		4,106		--
Total	$	135,180	$	115,749	$	19,431

The FCA mechanism lessens the risk of loss from market price changes because it provides for recovery of most fuel costs.

Other

The Company is a party to litigation arising in the normal course of business. The Company regularly analyzes current information and, as necessary, provides accruals for liabilities that are probable of occurring and that can be reasonably estimated. The Company believes the effect on its consolidated results of operations, financial position and cash flows, if any, for the disposition of all matters pending as of June 30, 2011 will not be material.

Contingencies, by their nature, relate to uncertainties that require the Company’s management to exercise judgment both in assessing the likelihood that a liability has been incurred as well as in estimating the amount of potential loss. The most significant contingencies impacting the Company’s consolidated financial statements are those related to product warranty, environmental remediation, litigation matters, possible liquidated damages and the resolution of matters related to open tax years. Should any of these items result in a liability being incurred, the range of loss could be as high as $9.0 million. Additionally, we may become subject to significant claims of which we are unaware, or the claims of which we are aware may result in our incurring a significantly greater liability than we anticipate.

10. Short-Term and Long-Term Borrowings

On March 3, 2011 OTP entered into an Amended and Restated Credit Agreement (the OTP Credit Agreement) with the Banks named therein. The OTP Credit Agreement provides for a $170 million line of credit that may be increased to $250 million on the terms and subject to the conditions described in the OTP Credit Agreement. The OTP Credit Agreement is an unsecured revolving credit facility that OTP can draw on to support the working capital needs and other capital requirements of its operations, including letters of credit in an aggregate amount not to exceed $50 million outstanding at any time. Borrowings under the line of credit currently bear interest at LIBOR plus 1.5%, subject to adjustment based on the ratings of OTP’s senior unsecured debt. Under the OTP Credit Agreement OTP is required to pay the Banks’ commitment fees based on the average daily unused amount available to be drawn under the revolving credit facility. The OTP Credit Agreement expires on March 3, 2016.

The OTP Credit Agreement contains a number of restrictions on the business of OTP, including restrictions on its ability to merge, sell assets, create or incur liens on assets, guarantee the obligations of any other party, and engage in transactions with related parties. The OTP Credit Agreement also contains affirmative covenants and events of default. The OTP Credit Agreement does not include provisions for the termination of the agreement or the acceleration of repayment of amounts outstanding due to changes in OTP’s credit ratings. The OTP Credit Agreement amends and restates the $170 million Credit Agreement dated as of July 30, 2008 among OTP (formerly known as Otter Tail Corporation, dba Otter Tail Power Company), the Banks named therein, as amended by a First Amendment to Credit Agreement dated as of April 21, 2009 and a Second Amendment to Credit Agreement dated as of June 22, 2009.

The OTP Credit Agreement also contains certain financial covenants. Specifically, OTP may not permit the ratio of its Interest-bearing Debt to Total Capitalization (as defined in the OTP Credit Agreement) to be greater than 0.60 to 1.00 or permit its Interest and Dividend Coverage Ratio (as defined in the OTP Credit Agreement) to be less than 1.50 to 1.00.

On March 18, 2011 Otter Tail Corporation borrowed $1.5 million under a Partnership in Assisting Community Expansion loan to finance capital investments at Northern Pipe Products, Inc. (NPP), the Company’s PVC pipe manufacturing subsidiary located in Fargo, North Dakota. The ten-year unsecured note bears interest at 2.54% with monthly principal and interest payments through March 2021. On April 6, 2011 Otter Tail Corporation borrowed $0.5 million under a North Dakota Development Fund loan to finance additional capital investments at NPP. The seven-year unsecured note bears interest at 3.95% with monthly principal and interest payments through April 1, 2018.

11. Class B Stock Options of Subsidiary

In conjunction with the sale of IPH on May 6, 2011, all 363 outstanding IPH Class B common share options were cancelled by mutual agreement between the issuer and the holders of the options and a liability to the holders of the options was established based on the fair value of the options on May 6, 2011. The liability was assumed by the new owner of IPH. The options were adjusted to their fair value based on the fair value of an underlying share of Class B Common Stock of $2,973.90 per share on May 6, 2011. The book value of IPH Class B common share options prior to their cancellation on May 6, 2011 was based on an IPH Class B common share value of $2,085.88 per share. The $322,000 difference between the fair value and book value of the options was charged to retained earnings and earnings available for common shares were reduced by $322,000 in the second quarter of 2011.

13. Fair Value of Financial Instruments

The following methods and assumptions were used to estimate the fair value of each class of financial instruments for which it is practicable to estimate that value:

Cash and Short-Term Investments —The carrying amount approximates fair value because of the short-term maturity of those instruments.

Long-Term Debt —The fair value of the Company's long-term debt is estimated based on the current rates available to the Company for the issuance of debt. The Company’s long-term debt subject to variable interest rates approximates fair value.

	June 30, 2011						December 31, 2010
(in thousands)	Carrying Amount			Fair Value			Carrying Amount			Fair Value
Cash and Short-Term Investments	$	--		$	--		$	--		$	--
Long-Term Debt		(433,715	)		(466,010	)		(434,812	)		(474,307	)

15. Income Tax Expense (Benefit) – Continuing Operations

	Three Months Ended June 30,								Six Months Ended June 30,
(in thousands)	2011			2010			Variance		2011			2010			Variance
Income (Loss) Before Income Taxes – Continuing Operations	$	6,535		$	(24,044	)	$	30,579	$	13,717		$	(18,833	)	$	32,550
Income Tax Expense (Benefit) - Continuing Operations		537			(7,769	)		8,306		2,085			(6,018	)		8,103
Effective Income Tax Rate – Continuing Operations		8.2	%		32.3	%				15.2	%		32.0	%

The increase in Income Tax Expense (Benefit) - Continuing Operations for the three months ended June 30, 2011 compared with the three months ended June 30, 2010 is mainly due to the increase in income before income taxes between the quarters, but also due to DMI deferring recognition of tax benefits in the second quarter of 2011 on the operating losses of its Canadian wind tower manufacturing company until those operations become profitable. DMI’s deferred tax benefits totaled $1.0 million in the second quarter of 2011. The Company’s effective income tax rate for the three months ended June 30, 2011 was decreased mainly as a result of recording $1.9 million in federal production tax credits (PTCs) earned on kilowatt-hours (kwh) generated from tax credit qualified wind turbines owned by OTP.

The increase in Income Tax Expense (Benefit) - Continuing Operations for the six months ended June 30, 2011 compared with the six months ended June 30, 2010 is mainly due to the increase in income before income taxes between the periods but also due to DMI deferring recognition of tax benefits in the first six months of 2011 on the operating losses of its Canadian wind tower manufacturing company until those operations become profitable. DMI’s deferred tax benefits totaled $1.8 million in the first half of 2011. The Company’s effective income tax rate for the six months ended June 30, 2011 decreased as a result of recording $3.9 million in federal PTCs earned on kwhs generated from tax credit qualified wind turbines owned by OTP.

17. Discontinued Operations

On May 6, 2011, the Company completed the sale of IPH to affiliates of Novacap Industries III, L.P. for approximately $87.0 million in cash. The proceeds from the sale, net of $3.0 million deposited in an escrow account, were used to pay down borrowings under the Otter Tail Corporation Credit Agreement. In the second quarter of 2011, Wylie decided to exit its heavy haul/specialized shipment and transportation of wind turbine components business, determining that the risks associated with continuing to provide these services outweighed any potential profits to be derived from these operations. The financial position, results of operations, and cash flows of IPH and Wylie’s specialized shipment and transportation of wind turbine components business are reported as discontinued operations in the Company’s consolidated financial statements as of June 30, 2011 and December 31, 2010, and for the three and six month periods ended June 30, 2011 and 2010. Following are summary presentations of the results of discontinued operations for the three and six month periods ended June 30, 2011 and 2010 and of the major components of assets and liabilities of discontinued operations as of June 30, 2011 and December 31, 2010:

18. Subsequent Events

On July 29, 2011, OTP entered into a Note Purchase Agreement (the 2011 Note Purchase Agreement) with the Purchasers named therein, pursuant to which OTP has agreed to issue to the Purchasers in a private placement transaction $140 million aggregate principal amount of OTP’s 4.63% Senior Unsecured Notes due December 1, 2021 (the 2021 Notes). The 2021 Notes are expected to be issued on December 1, 2011, subject to the satisfaction of certain customary conditions to closing. OTP intends to use a portion of the proceeds of the 2021 Notes to retire $90 million aggregate principal amount of OTP’s 6.63% Senior Notes due December 1, 2011 and $10.4 million aggregate principal amount of its pollution control refunding revenue bonds due December 1, 2012. The remaining proceeds of the 2021 Notes will be used to repay short-term debt of OTP, to pay fees and expenses related to the issuance of the 2021 Notes and for other general corporate purposes.

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations

RESULTS OF OPERATIONS

Following is an analysis of our operating results by business segment for the three and six month periods ended June 30, 2011 and 2010, followed by a discussion of changes in our consolidated financial position during the six months ended June 30, 2011 and our business outlook for the remainder of 2011.

C omparison of the Three Months Ended June 30, 2011 and 2010

Consolidated operating revenues were $317.0 million for the three months ended June 30, 2011 compared with $251.3 million for the three months ended June 30, 2010. Operating income was $14.6 million for the three months ended June 30, 2011 compared with an operating loss of $15.2 million for the three months ended June 30, 2010. The Company recorded diluted earnings per share from continuing operations of $0.16 for the three months ended June 30, 2011 compared to $(0.46) for the three months ended June 30, 2010 and total diluted earnings per share of $0.51 for the three months ended June 30, 2011 compared to $(0.40) for the three months ended June 30, 2010.

Amounts presented in the segment tables that follow for operating revenues, cost of goods sold and other nonelectric operating expenses for the three month periods ended June 30, 2011 and 2010 will not agree with amounts presented in the consolidated statements of income due to the elimination of intersegment transactions. The amounts of intersegment eliminations by income statement line item are listed below:

The slight decrease in retail sales revenues included a 2.4% increase in retail kilowatt-hour (kwh) sales that was more than offset by decreases of $0.6 million in Minnesota Conservation Improvement Program (MNCIP) accrued incentives and $0.5 million in Fuel Clause Adjustment (FCA) revenues. The increase in retail kwh sales was driven by colder weather in spring 2011, as heating degree days were up 37.1% over the second quarter of 2010. FCA revenues decreased as a result of reductions in the volume and price of power purchased to serve retail load.

Wholesale electric revenues from company-owned generation decreased $1.6 million due to an 18.8% decline in wholesale kwh sales combined with a 15.7% reduction in the average price per wholesale kwh sold as a result of lower demand in wholesale markets. Net gains from energy trading activities, including net mark-to-market gains on forward energy contracts increased $0.2 million as a result of a slight increase in mark-to-market gains on Otter Tail Power Company’s (OTP) open energy contracts. Other electric operating revenues increased $2.0 million as a result of: (1) a June 2010 accrual of a $1.1 million refund of a portion of revenues collected from OTP’s Big Stone II partners, (2) a $0.7 million increase in transmission tariff and services revenue, and (3) $0.2 million in payments received by Otter Tail Energy Services Company (OTESCO) in the second quarter of 2011 for providing assistance to another regional electric utility in obtaining easements for a high voltage transmission line.

The increase in fuel costs is due to a 2.8% increase in fuel costs per kwh of generation combined with 0.7% increase in kwhs generated from OTP’s steam-powered and combustion turbine generators. The cost of purchased power for retail sales decreased $2.5 million as a result of a 26.4% decrease in kwhs purchased , partially offset by a 2.9% increase in the cost per kwh purchased . OTP used 7.6% more of its own generation to serve its retail customers in the second quarter of 2011 compared with the second quarter of 2010, due in part to a 13.5% increase in generation from company-owned wind turbines between the quarters. The decrease in other operation and maintenance expenses is mainly due to $0.7 million increase in capitalized administrative and general expenses related to an increase in construction activity between the quarters.

Wind Energy

In the second quarter of 2011, E. W. Wylie Corporation (Wylie) exited the wind-heavy haul business. Accordingly, the results of operations of Wylie’s wind-heavy haul business are reported as discontinued operations.

The increase in revenues in our Manufacturing segment relates to the following:

●	Revenues at BTD Manufacturing, Inc. (BTD), our metal parts stamping and fabrication company, increased $9.3 million as a result of higher sales volume due to improved customer demand.

●	Revenues at T.O. Plastics, Inc. (T.O. Plastics), our manufacturer of thermoformed plastic and horticultural products, decreased by $0.6 million due to decreases in sales volumes of all product lines except horticultural products.

●	Revenues at ShoreMaster, Inc. (ShoreMaster), our waterfront equipment business, increased $0.2 million mainly as a result of higher sales of residential products.

The increase in cost of goods sold in our Manufacturing segment relates to the following:

●	Cost of goods sold at BTD increased $7.7 million mainly as a result of increased sales volume.

●	Cost of goods sold at T.O. Plastics decreased $0.5 million as a result of the decrease in sales volume.

●	Cost of goods sold at ShoreMaster was unchanged between the quarters.

The net decrease in operating expenses in our Manufacturing segment is due to the following:

●	Operating expenses at BTD increased $0.5 million mainly due to increased salary and benefit costs related to workforce expansion.

●	Operating expenses at T.O. Plastics did not change between the quarters.

●	Operating expenses at ShoreMaster decreased $2.4 million, reflecting a $2.2 million increase to its allowance for doubtful accounts in its residential and commercial businesses in the second quarter of 2010.

ShoreMaster recorded a $19.7 million asset impairment charge in the second quarter of 2010. In light of ongoing economic uncertainty and delayed economic recovery ShoreMaster revised its sales and operating cash flow projections downward in the second quarter of 2010, which resulted in a reassessment of the carrying value of its recorded goodwill. The fair value determination indicated ShoreMaster’s goodwill and other intangible assets were 100% impaired and its long-lived assets were partially impaired.

Revenues from scanning and other related services decreased $1.2 million due to a 7.5% decrease in scans performed, partially offset by a 4.9% increase in revenue per scan, reflecting the planned discontinuance of portable x-ray services. Revenues from equipment sales increased $0.5 million due to an increase in revenues from sales of equipment used in the imaging side of the business. The decrease in cost of goods sold reflects a $2.8 million reduction in equipment rental costs directly related to efforts by the Health Services segment to right-size its fleet of imaging assets by exercising purchase options on productive imaging assets coming off lease and not renewing leases on underutilized imaging assets. As of June 30, 2011 there were 121 owned and leased assets in the fleet compared with 134 at June 30, 2010. The increase in operating expenses reflects a $0.5 million gain on the sale of fixed assets in the second quarter of 2010. No comparable gain was recorded in the second quarter of 2011. The $0.8 million increase in depreciation expense reflects an increase in owned equipment compared with a year ago.

Corporate

Corporate includes items such as corporate staff and overhead costs, the results of our captive insurance company and other items excluded from the measurement of operating segment performance. Corporate is not an operating segment. Rather it is added to operating segment totals to reconcile to totals on our consolidated statements of income.

Operating Expenses	$	3,424	$	3,880	$	(456	)		(11.8	)
Depreciation and Amortization		142		134		8			6.0

The decrease in corporate operating expenses is mainly due to lower salary and employee benefit costs.

Interest Charges

Interest charges decreased $0.2 million in the second quarter of 2011 compared with the second quarter of 2010 mainly as a result of a $14.2 million decrease in the average balance of short-term debt outstanding between the quarters, due in part to the pay down of borrowings under the corporation’s line of credit facility from proceeds from the sale of Idaho Pacific Holdings, Inc. (IPH) in May 2011.

Other Income

Other income increased $0.6 million in the second quarter of 2011 compared with the second quarter of 2010, mainly as a result of increases in allowance for equity funds used during construction at OTP and a decrease in foreign currency transaction losses in the Canadian operations of DMI, between the quarters.

The increase in Income Tax Expense (Benefit) - Continuing Operations for the three months ended June 30, 2011 compared with the three months ended June 30, 2010 is mainly due to the increase in income before income taxes between the quarters, but is also due to DMI deferring recognition of tax benefits in the second quarter of 2011 on the operating losses of its Canadian operations until those operations become profitable. DMI’s deferred tax benefits totaled $1.0 million in the second quarter of 2011. Our effective income tax rate for the three months ended June 30, 2011 was decreased as a result of recording $1. 9 million in federal production tax credits (PTCs). Federal PTCs are recognized as wind energy is generated based on a per kwh rate prescribed in applicable federal statutes. North Dakota wind energy credits are based on dollars invested in qualifying facilities and are being recognized on a straight-line basis over 25 years.

Discontinued Operations

On May 6, 2011, we completed the sale of IPH to affiliates of Novacap Industries III, L.P. for approximately $87.0 million in cash. The proceeds from the sale, net of $3.0 million deposited in an escrow account, were used to pay down borrowings under our existing credit agreement. In the second quarter of 2011, Wylie decided to discontinue its heavy haul and specialized shipment and transportation of wind turbine components business. The results of operations of IPH and of Wylie’s wind turbine component transport business are reported as discontinued operations in our consolidated statements of income for the three months ended June 30, 2011 and 2010 as summarized in the table below:

The increase in retail sales revenues mainly is due to the following: (1) a $3.5 million increase in revenues due to a 3.1% increase in retail kwh sales driven by colder weather, as heating degree days were up 17.0% in the first half of 2011, (2) a $2.5 million increase from interim rates implemented in Minnesota in June 2010, and (3) a $1.1 million increase in Minnesota CIP surcharge revenues, offset by (4) a $3.5 million reduction in revenue related to a Minnesota interim rate refund accrued in the first half of 2011 for excess amounts collected under interim rates in effect since June 2010, and (5) a decrease in FCA revenues related to the $2.2 million reduction in purchased power costs to serve retail load.

Wholesale electric revenues from company-owned generation decreased $2.9 million as a result of a 21.5% decrease in revenue per wholesale kwh sold combined with a 12.7% decrease in wholesale kwh sales related to decreases in wholesale market prices and demand. Net gains from energy trading activities, including net mark-to-market gains on forward energy contracts decreased $1.5 million as a result of a reduction in mark-to-market gains on open energy contracts combined with a reduction in the volume of long-term forward energy contracts entered into in 2011. Other electric operating revenues increased $3.7 million as a result of: (1) a $1.4 million increase in transmission tariff and services revenue between the periods, (2) $1.2 million in payments from another regional electric utility to OTESCO in 2011 for access rights and assistance in obtaining easements for a high voltage transmission line on a wind farm site where OTESCO owns development rights, and (3) a June 2010 accrual of a $1.1 million refund of a portion of revenues collected from OTP’s Big Stone II partners.

The decrease in fuel costs is due to a 5.5% decrease in kwhs generated from OTP’s steam-powered and combustion turbine generators, partially offset by a 3.7% increase in the cost of fuel per kwh generated. The cost of purchased power for retail sales decreased $2.2 million as a result of a 24.2% decrease in the cost per kwh purchased due to lower market prices for electricity, partially offset by an 18.9% increase in kwhs purchased. The increase in kwhs purchased was due to a 1.3% decrease in kwhs generated for retail customers combined with a 3.1% increase in retail kwh sales.

FINANCIAL POSITION

The following table presents the status of our lines of credit as of June 30, 2011 and December 31, 2010:

(in thousands)	Line Limit		In Use on June 30, 2011			Restricted due to Outstanding Letters of Credit		Available on June 30, 2011		Available on December 31, 2010

1 In use amount includes $2,351,000 assigned to the heavy haul and specialized shipment and transportation of wind turbine components business of Wylie and reflected in Liabilities of Discontinued Operations on the Company’s June 30, 2011 consolidated balance sheet.

We believe we have the necessary liquidity to effectively conduct business operations for an extended period if needed. Our balance sheet is strong and we are in compliance with our debt covenants. Financial flexibility is provided by operating cash flows, unused lines of credit, strong financial coverages, investment grade credit ratings, and alternative financing arrangements such as leasing.

We believe our financial condition is strong and our cash, other liquid assets, operating cash flows, existing lines of credit, access to capital markets and borrowing ability because of investment-grade credit ratings, when taken together, provide adequate resources to fund ongoing operating requirements and future capital expenditures related to expansion of existing businesses and development of new projects. On May 11, 2009 we filed a shelf registration statement with the Securities and Exchange Commission under which we may offer for sale, from time to time, either separately or together in any combination, equity, debt or other securities described in the shelf registration statement. On March 17, 2010, we entered into a Distribution Agreement with J.P. Morgan Securities (JPMS) under which we may offer and sell our common shares from time to time through JPMS, as our distribution agent, up to an aggregate sales price of $75 million. Equity or debt financing will be required in the period 2011 through 2015 given the expansion plans related to our Electric segment to fund construction of new rate base investments, in the event we decide to reduce borrowings under our lines of credit or refund or retire early any of our presently outstanding debt or cumulative preferred shares, to complete acquisitions or for other corporate purposes. There can be no assurance that any additional required financing will be available through bank borrowings, debt or equity financing or otherwise, or that if such financing is available, it will be available on terms acceptable to us. If adequate funds are not available on acceptable terms, our businesses, results of operations and financial condition could be adversely affected. Also, our operating cash flow and access to capital markets can be impacted by macroeconomic factors outside our control. In addition, our borrowing costs can be impacted by changing interest rates on short-term and long-term debt and ratings assigned to us by independent rating agencies, which in part are based on certain credit measures such as interest coverage and leverage ratios.

Our dividend payout ratio has exceeded 100% in each of the last three years. The determination of the amount of future cash dividends to be declared and paid will depend on, among other things, our financial condition, improvement in earnings per share to levels in excess of the indicated annual dividend per share of $1.19, cash flows from operations, the level of our capital expenditures, restrictions under our credit facilities and our future business prospects. The decision to declare a quarterly dividend is reviewed quarterly by the Board of Directors.

DMI is party to a $40 million receivable sales agreement whereby designated customer accounts receivable may be sold to General Electric Capital Corporation on a revolving basis. The agreement is subject to renewal in March 2012. The current discount rate is 3-month LIBOR plus 4%. Accounts receivable totaling $28.1 million were sold in the first half of 2011. Discounts, fees and commissions charged to operating expense for the six months ended June 30, 2011 and 2010 were $253,000 and $107,000, respectively. The balance of receivables sold that was outstanding to the buyer as of June 30, 2011 was $13.0 million. The sales of these accounts receivable are reflected as a reduction of accounts receivable in our consolidated balance sheets and the proceeds are included in the cash flows from operating activities in our consolidated statement of cash flows.

Cash provided by operating activities from continuing operations was $40.7 million for the six months ended June 30, 2011 compared with cash provided by operating activities from continuing operations of $49.8 million for the six months ended June 30, 2010. The $9.1 million decrease in cash provided by operating activities from continuing operations reflects an $18.8 million increase in cash used for working capital items between the periods, offset by a $4.7 million increase in net income from continuing operations, net of the $19.7 million non-cash impairment charge recorded in the second quarter of 2010, and a $6.6 million increase in cash from changes in deferred income taxes and other deferred debits.

Net cash used in investing activities of continuing operations was $45.0 million for the six months ended June 30, 2011 compared to $37.4 million for the six months ended June 30, 2010. Cash used for capital expenditures at the electric utility increased $6.8 million between the periods mainly related to expenditures for the Fargo to St. Cloud and Bemidji to Grand Rapids CapX2020 transmission line construction projects.

Net cash used in financing activities from continuing operations increased $58.4 million in the six months ended June 30, 2011 compared with the six months ended June 30, 2010 mainly due to a $61.4 million decrease in short-term borrowings and checks issued in excess of cash, net of a decrease in cash used to retire long-term debt between the periods. We paid $58.7 million to retire long-term debt in the first half of 2010 but increased short-term borrowings by $60.0 million over the same period. Cash used to repay short-term borrowings and checks written in excess of cash totaled $55.1 million in the first half of 2011. The cash used to pay down short-term debt in the first half of 2011 came from $84.4 million in net proceeds from the sale of IPH in May 2011.

Our contractual obligations reported in the table on page 56 of our Annual Report on Form 10-K for the year ended December 31, 2010 have increased by $45.2 million: Our “Capacity and Energy Requirements” have increased by $1.1 million for 2011, $8.8 million for 2012 and 2013, and $15.9 million for 2014 and 2015 related to long-term power purchase agreements entered into with a regional generator and supplier in the first quarter of 2011. Our “Coal Contracts (required minimums)” have increased by $5.7 million in 2011 and $13.7 million in 2012 related to an expansion and extension of an agreement to supply coal to OTP’s Hoot Lake Plant.

On May 11, 2009 we filed a shelf registration statement with the Securities and Exchange Commission under which we may offer for sale, from time to time, either separately or together in any combination, equity, debt or other securities described in the shelf registration statement.

On March 17, 2010, we entered into a Distribution Agreement (the Agreement) with JPMS. Pursuant to the terms of the Agreement, we may offer and sell our common shares from time to time through JPMS, as our distribution agent for the offer and sale of the shares, up to an aggregate sales price of $75 million. Under the Agreement, we will designate the minimum price and maximum number of shares to be sold through JPMS on any given trading day or over a specified period of trading days, and JPMS will use commercially reasonable efforts to sell such shares on such days, subject to certain conditions. We are not obligated to sell and JPMS is not obligated to buy or sell any of the shares under the Agreement. The shares, if issued, will be issued pursuant to our shelf registration statement, as amended. No shares have been sold pursuant to the Agreement.

On May 4, 2010 we entered into a $200 million Second Amended and Restated Credit Agreement (the Otter Tail Corporation Credit Agreement) with the Banks named therein, which is an unsecured revolving credit facility that we can draw on to support our nonelectric operations. Borrowings under the Otter Tail Corporation Credit Agreement bear interest at LIBOR plus 3.25%, subject to adjustment based on our senior unsecured credit ratings. The Otter Tail Corporation Credit Agreement expires on May 4, 2013. The Otter Tail Corporation Credit Agreement contains a number of restrictions on us and the businesses of Varistar Corporation (Varistar), our wholly owned subsidiary, and its material subsidiaries, including restrictions on our and their ability to merge, sell assets, incur indebtedness, create or incur liens on assets, guarantee the obligations of certain other parties and engage in transactions with related parties. The Otter Tail Corporation Credit Agreement also contains affirmative covenants and events of default. The Otter Tail Corporation Credit Agreement does not include provisions for the termination of the agreement or the acceleration of repayment of amounts outstanding due to changes in our credit ratings. Our obligations under the Otter Tail Corporation Credit Agreement are guaranteed by certain of our material subsidiaries. Outstanding letters of credit issued by us under the Otter Tail Corporation Credit Agreement can reduce the amount available for borrowing under the line by up to $50 million. The Otter Tail Corporation Credit Agreement has an accordion feature whereby the line can be increased to $250 million as described in the Otter Tail Corporation Credit Agreement.

On March 18, 2011 we borrowed $1.5 million under a Partnership in Assisting Community Expansion loan to finance capital investments at Northern Pipe Products, Inc. (NPP), our PVC pipe manufacturing subsidiary located in Fargo, North Dakota. The ten-year unsecured note bears interest at 2.54% with monthly principal and interest payments through March 2021. On April 6, 2011 we borrowed $0.5 million under a North Dakota Development Fund loan to finance additional capital investments at NPP. The seven-year unsecured note bears interest at 3.95% with monthly principal and interest payments through April 1, 2018.

On July 29, 2011, OTP entered into a Note Purchase Agreement (the 2011 Note Purchase Agreement) with the Purchasers named therein, pursuant to which OTP has agreed to issue to the Purchasers in a private placement transaction $140 million aggregate principal amount of OTP’s 4.63% Senior Unsecured Notes due December 1, 2021 (the 2021 Notes). The 2021 Notes are expected to be issued on December 1, 2011, subject to the satisfaction of certain customary conditions to closing. OTP intends to use a portion of the proceeds of the 2021 Notes to retire $90 million aggregate principal amount of OTP’s 6.63% Senior Notes due December 1, 2011 (the 2011 Notes) and $10.4 million aggregate principal amount of its pollution control refunding revenue bonds due December 1, 2012. The 2011 Notes remain classified as long-term debt because OTP has made arrangements to refinance this debt with borrowings under the 2011 Note Purchase Agreement

The note purchase agreement relating to the 2011 Notes, as amended (the 2001 Note Purchase Agreement), the note purchase agreement relating to our $50 million 8.89% senior note due November 30, 2017, as amended (the Cascade Note Purchase Agreement), the note purchase agreement relating to OTP’s $155 million senior unsecured notes issued in four series consisting of $33 million aggregate principal amount of 5.95% Senior Unsecured Notes, Series A, due 2017; $30 million aggregate principal amount of 6.15% Senior Unsecured Notes, Series B, due 2022; $42 million aggregate principal amount of 6.37% Senior Unsecured Notes, Series C, due 2027; and $50 million aggregate principal amount of 6.47% Senior Unsecured Notes, Series D, due 2037, as amended (the 2007 Note Purchase Agreement) and the 2011 Note Purchase Agreement each states that the applicable obligor may prepay all or any part of the notes issued thereunder (in an amount not less than 10% of the aggregate principal amount of the notes then outstanding in the case of a partial prepayment) at 100% of the principal amount prepaid, together with accrued interest and a make-whole amount. Each of the Cascade Note Purchase Agreement, the 2001 Note Purchase Agreement and the 2011 Note Purchase Agreement states in the event of a transfer of utility assets put event, the noteholders thereunder have the right to require the applicable obligor to repurchase the notes held by them in full, together with accrued interest and a make-whole amount, on the terms and conditions specified in the respective note purchase agreements. The 2007 Note Purchase Agreement and the 2011 Note Purchase Agreement each also states that OTP must offer to prepay all of the outstanding notes issued thereunder at 100% of the principal amount together with unpaid accrued interest in the event of a change of control of OTP. The 2001 Note Purchase Agreement, the 2007 Note Purchase Agreement, the Cascade Note Purchase Agreement and the 2011 Note Purchase Agreement each contains a number of restrictions on the applicable obligor and its subsidiaries. These include restrictions on the obligor’s ability and the ability of the obligor’s subsidiaries to merge, sell assets, create or incur liens on assets, guarantee the obligations of any other party, and engage in transactions with related parties. Our obligations under the Cascade Note Purchase Agreement are guaranteed by certain of our material subsidiaries. Cascade owned approximately 9.6% of the Company’s outstanding common stock as of December 31, 2010.

On June 23, 2010 we entered into Amendment No. 3 to the Cascade Note Purchase Agreement. Amendment No. 3 amends certain covenants and related definitions contained in the Cascade Note Purchase Agreement to, among other things, provide us and our material subsidiaries with additional flexibility to incur certain customary liens, make certain investments, and give certain guaranties, in each case under the circumstances set forth in Amendment No. 3. On July 29, 2010 we entered into Amendment No. 4 to the Cascade Note Purchase Agreement, which was effective June 30, 2010. The amendments contained in Amendment No. 4 permit us to exclude impairment charges and write-offs of assets from the calculation of the interest charges coverage ratio required to be maintained under the Cascade Note Purchase Agreement.

Financial Covenants

As of June 30, 2011 the Company and OTP were each in compliance with the financial statement covenants that existed in their respective debt agreements.

No Credit or Note Purchase Agreement contains any provisions that would trigger an acceleration of the related debt as a result of changes in the credit rating levels assigned to the related obligor by rating agencies.

Our and OTP’s borrowing agreements require us and OTP, respectively, to comply with certain financial covenants, and upon the issuance of the 2021 Notes, the 2011 Note Purchase Agreement will require OTP to comply with similar covenants. Specifically:

●	Under the Otter Tail Corporation Credit Agreement, we may not permit the ratio of our Interest-bearing Debt to Total Capitalization to be greater than 0.60 to 1.00 or permit our Interest and Dividend Coverage Ratio to be less than 1.50 to 1.00 (each measured on a consolidated basis), as provided in the Credit Agreement. As of June 30, 2011 our Interest and Dividend Coverage Ratio calculated under the requirements of the Otter Tail Corporation Credit Agreement was 1.57 to 1.00.

●	Under the Cascade Note Purchase Agreement, we may not permit our ratio of Consolidated Debt to Consolidated Total Capitalization to be greater than 0.60 to 1.00 or our Interest Charges Coverage Ratio to be less than 1.50 to 1.00 (each measured on a consolidated basis), permit the ratio of OTP’s Debt to OTP’s Total Capitalization to be greater than 0.60 to 1.00, or permit Priority Debt to exceed 20% of Varistar Consolidated Total Capitalization, as provided in the Cascade Note Purchase Agreement. As of June 30, 2011 our Interest Charges Coverage Ratio calculated under the requirements of the Cascade Note Purchase Agreement was 1.51 to 1.00

●	Under the OTP Credit Agreement and, upon the issuance of the 2021 Notes, under the 2011 Note Purchase Agreement, OTP may not permit the ratio of its Interest-bearing Debt to Total Capitalization to be greater than 0.60 to 1.00 or permit its Interest and Dividend Coverage Ratio to be less than 1.50 to 1.00, as provided in the related agreement. As of June 30, 2011 OTP’s Interest and Dividend Coverage Ratio calculated under the requirements of each such agreement was 3.40 to 1.00.

●	Under the 2001 Note Purchase Agreement, the 2007 Note Purchase Agreement and the financial guaranty insurance policy with Ambac Assurance Corporation relating to certain pollution control refunding bonds, OTP may not permit the ratio of its Consolidated Debt to Total Capitalization to be greater than 0.60 to 1.00 or permit its Interest and Dividend Coverage Ratio (or, in the case of the 2001 Note Purchase Agreement, its Interest Charges Coverage Ratio) to be less than 1.50 to 1.00, in each case as provided in the related borrowing or insurance agreement. In addition, under the 2001 Note Purchase Agreement, the 2007 Note Purchase Agreement and, upon the issuance of the 2021 Notes, under the 2011 Note Purchase Agreement, OTP may not permit its Priority Debt to exceed 20% of its Total Capitalization, as provided in the related agreement. As of June 30, 2011 OTP’s Interest and Dividend Coverage Ratio and Interest Charges Coverage Ratio, calculated under the requirements of each such agreement was 3.40 to 1.00.

As of June 30, 2011 our interest-bearing debt to total capitalization was 0.42 to 1.00 on a fully consolidated basis and 0.48 to 1.00 for OTP.

OFF-BALANCE-SHEET ARRANGEMENTS

We and our subsidiary companies have outstanding letters of credit totaling $10.6 million, but our line of credit borrowing limits are only restricted by $2.7 million of the outstanding letters of credit. We do not have any other off-balance-sheet arrangements or any relationships with unconsolidated entities or financial partnerships. These entities are often referred to as structured finance special purpose entities or variable interest entities, which are established for the purpose of facilitating off-balance-sheet arrangements or for other contractually narrow or limited purposes. We are not exposed to any financing, liquidity, market or credit risk that could arise if we had such relationships.

2011 BUSINESS OUTLOOK

The following updated guidance considers the cyclical nature of some of our businesses and reflects challenges presented by current economic conditions and our plans and strategies for improving future operating results.

Our updated 2011 earnings per share guidance range is as follows:

2011 Earnings Per Share Guidance Range
	Previous Guidance						Current Guidance
	Low			High			Low			High
Electric	$	.99		$	1.04		$	1.01		$	1.06
Wind Energy		(.40	)		(.25	)		(.80	)		(.50	)
Manufacturing		.25			.29			.25			.30
Construction		.05			.08			.05			.08
Plastics		.05			.08			.10			.13
Health Services		.00			.04			.01			.05
Corporate		(.20	)		(.18	)		(.20	)		(.18	)
Total – Continuing Operations	$	.74		$	1.10		$	.42		$	.94
Earnings – Discontinued Operations:
IPH		.06			.07			.07			.07
E.W. Wylie Heavy Haul - Wind								(.12	)		(.08	)
Gain on Sale of IPH		.35			.38			.35			.37
Total	$	1.15		$	1.55		$	.72		$	1.30

Contributing to our earnings guidance for 2011 are the following items:

●	We expect an increase in net income from our Electric segment in 2011 compared to 2010 and from previously announced guidance. This is based on anticipated sales growth and rate and rider recovery increases, an increase in capitalized interest costs related to larger construction expenditures and reductions in operating and maintenance expense in 2011 due to lower benefit costs.

●	Our 2011 earnings guidance for our Wind Energy segment reflects the following factors:

	o	We expect losses at DMI resulting from productivity challenges, a decrease in the number of towers produced, increased price pressure on new orders, and potential exposure to liquidated damages, warranty claims, or remediation costs related to past production issues. We anticipate that tower production for the remainder of 2011 will decrease from previous forecasts. This forecast decrease in tower demand primarily results from a general softening in the wind industry. The resulting decrease in production levels will offset productivity gains achieved over the past quarter and increase the fixed charge allocation to the remaining towers produced. Additionally, DMI continues to face pressures to reduce price due to over capacity in the U.S. market, and significantly lower steel costs available to Asian manufacturers.

	o	We exited Wylie’s wind-heavy haul business in the second quarter of 2011. Accordingly, the results of operations from this part of the business have been reclassified to discontinued operations. We expect the continuing flatbed trucking operations to be near breakeven levels for 2011

	o	Backlog in the Wind Energy segment is $82 million for 2011 compared with $68 million one year ago.

●	We expect earnings from our Manufacturing segment to increase from our original 2011 guidance as a result of increased order volume and continuing improvement in economic conditions in the industries BTD serves. ShoreMaster is expecting significantly improved performance as a result of bringing costs in line with current revenue levels and absent last year’s $15.6 million net-of-tax noncash impairment charge. T.O. Plastics is expected to have slightly better earnings in 2011 compared with 2010. Backlog for the manufacturing companies for 2011 is approximately $62 million compared with $47 million one year ago.

●	We expect higher net income from our Construction segment in 2011 as the economy improves and the construction companies record earnings on a higher volume of jobs in progress. Backlog for the construction businesses is $84 million for 2011 compared with $65 million one year ago.

●	We are increasing our earnings expectations for our Plastics segment given its strong second quarter 2011 performance.

●	We expect a slight increase in earnings from our previously issued guidance for our Health Services segment in 2011 as the benefits of implementing its asset reduction plan continue to be realized.

●	Corporate general and administrative costs are expected to decrease in 2011, compared with 2010, as a result of recent reductions in employee count and associated decreases in benefit costs.

●	The net earnings and the gain on sale of IPH are now reflective of the actual results as the sale of the business closed in May 2011. In addition, we exited the wind-heavy haul operations of E.W. Wylie in the second quarter of 2011. The net loss reflected in the guidance table is the result of actual operating activity of this business and an estimate of any other potential costs that could occur as the business winds down. There was no gain or loss incurred on disposal of the asset fleet associated with Wylie’s wind-heavy haul business.

The sale of IPH was a strategic decision by management to monetize a currently strong earning asset and use the proceeds to pay down short-term borrowings. This frees up liquidity going forward for upcoming Electric segment capital investments and helps ease the need to rely on the capital markets to fully fund these expenditures. We will continue to review our portfolio to see where additional opportunities exist to improve our risk profile, improve credit metrics and generate additional sources of cash to support the future capital expenditure plans of our Electric segment. Future IPH earnings forfeited through the sale of IPH are expected to be replaced by increased utility earnings over the next three years as the utility makes investments in its current capital plan. This will result in a larger percentage of the corporation’s earnings coming from its most stable and relatively predictable business, OTP, and is consistent with the strategy to grow this business given its current investment opportunities.

We currently anticipate the following capital expenditures and electric utility average rate base for 2011 through 2013:

(in millions)	2011		2012		2013
Capital Expenditures:
Electric Segment:
Transmission	$	23	$	31	$	65
Environmental		4		49		97
Other		40		50		57
Total Electric Segment	$	67	$	130	$	219
Nonelectric Segments		40		41		48
Total Capital Expenditures	$	107	$	171	$	267
Total Electric Utility Average Rate Base	$	651	$	722	$	876

Execution on the currently anticipated electric utility capital expenditure plan is expected to grow rate base and be a key driver in increasing utility earnings over the 2011 through 2013 timeframe. We intend to maintain an equity to total capitalization ratio near its present level of 51% in our Electric segment and will seek to earn our authorized overall return on equity of approximately 10.5% in the utility’s regulatory jurisdictions .

Regarding the collective operating companies in our nonelectric segments, there is a general expectation that business will strengthen in 2012 and 2013, as the U.S. economy slowly recovers. This is expected to lead to increased demand for our industrial products and services, generating higher revenues. This expectation, coupled with cost reductions that have taken place across the Company, should result in rising earnings per share for our nonelectric businesses as a whole.

Critical Accounting Policies Involving Significant Estimates

The discussion and analysis of the financial statements and results of operations are based on our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of these consolidated financial statements requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities.

We use estimates based on the best information available in recording transactions and balances resulting from business operations. Estimates are used for such items as depreciable lives, asset impairment evaluations, tax provisions, collectability of trade accounts receivable, self-insurance programs, unbilled electric revenues, accrued renewable resource and transmission rider revenues, valuations of forward energy contracts, contingent liabilities, service contract maintenance costs, percentage-of-completion and actuarially determined benefits costs and liabilities. As better information becomes available or actual amounts are known, estimates are revised. Operating results can be affected by revised estimates. Actual results may differ from these estimates under different assumptions or conditions. Management has discussed the application of these critical accounting policies and the development of these estimates with the Audit Committee of the Board of Directors. A discussion of critical accounting policies is included under the caption “Critical Accounting Policies Involving Significant Estimates” on pages 61 through 64 of our Annual Report on Form 10-K for the year ended December 31, 2010. There were no material changes in critical accounting policies or estimates during the quarter ended June 30, 2011.

Forward Looking Information - Safe Harbor Statement Under the Private Securities Litigation Reform Act of 1995

In connection with the "safe harbor" provisions of the Private Securities Litigation Reform Act of 1995 (the Act), we have filed cautionary statements identifying important factors that could cause our actual results to differ materially from those discussed in forward-looking statements made by or on behalf of the Company. When used in this Form 10-Q and in future filings by the Company with the Securities and Exchange Commission, in our press releases and in oral statements, words such as "may", "will", "expect", "anticipate", "continue", "estimate", "project", "believes" or similar expressions are intended to identify forward-looking statements within the meaning of the Act and are included, along with this statement, for purposes of complying with the safe harbor provision of the Act.

The following factors, among others, could cause our actual results to differ materially from those discussed in the forward-looking statements:

●	We are subject to federal and state legislation, regulations and actions that may have a negative impact on our business and results of operations.

●	Federal and state environmental regulation could require us to incur substantial capital expenditures and increased operating costs.

●	Volatile financial markets and changes in our debt ratings could restrict our ability to access capital and could increase borrowing costs and pension plan and postretirement health care expenses.

●	We rely on access to both short- and long-term capital markets as a source of liquidity for capital requirements not satisfied by cash flows from operations. If we are not able to access capital at competitive rates, our ability to implement our business plans may be adversely affected.

●	We may experience fluctuations in revenues and expenses related to our operations, which may cause our financial results to fluctuate and could impair our ability to make distributions to our shareholders or scheduled payments on our debt obligations, or to meet covenants under our borrowing agreements.

●	Disruptions, uncertainty or volatility in the financial markets can also adversely impact our results of operations, the ability of our customers to finance purchases of goods and services, and our financial condition, as well as exert downward pressure on stock prices and/or limit our ability to sustain our current common stock dividend level.

●	We are not currently required to make any contributions to our defined benefit pension plan in 2011. We could make discretionary contributions to the plan or could be required to contribute additional capital to the pension plan in future years if the market value of pension plan assets significantly declines in the future, plan assets do not earn in line with our long-term rate of return assumptions or relief under the Pension Protection Act is no longer granted.

●	Any significant impairment of our goodwill would cause a decrease in our asset values and a reduction in our net operating income.

●	A sustained decline in our common stock price below book value or declines in projected operating cash flows at any of our operating companies may result in goodwill impairments that could adversely affect our results of operations and financial position, as well as financing agreement covenants.

●	The inability of our subsidiaries to provide sufficient earnings and cash flows to allow us to meet our financial obligations and debt covenants and pay dividends to our shareholders could have an adverse effect on us.

●	Economic conditions could negatively impact our businesses.

●	If we are unable to achieve the organic growth we expect, our financial performance may be adversely affected.

●	Our plans to grow and realign our diversified business mix through capital projects, acquisitions and dispositions may not be successful, which could result in poor financial performance.

●	Our plans to grow and operate our nonelectric businesses could be limited by state law.

●	Our subsidiaries enter into production and construction contracts, including contracts for new product designs, which could expose them to unforeseen costs and costs not within their control, which may not be recoverable and could adversely affect our results of operations and financial condition.

●	Significant warranty claims in excess of amounts normally reserved for such items could adversely affect our results of operations and financial condition. Also, expenses associated with remediation activities in the wind energy segment could be substantial. The potential exists for multiple claims based on one defect repeated throughout the production process or for claims where the cost to repair or replace the defective part is highly disproportionate to the original cost of the part. If we are required to cover remediation expenses in addition to regular warranty coverage, we could be required to accrue additional expenses and experience additional unplanned cash expenditures which could adversely affect our consolidated results of operations and financial condition.


●	We are subject to risks associated with energy markets.

●	We are subject to risks and uncertainties related to the timing and recovery of deferred tax assets which could have a negative impact on our net income in future periods.

●	Certain of our operating companies sell products to consumers that could be subject to recall.

●	Competition is a factor in all of our businesses.

●	Actions by the regulators of our electric operations could result in rate reductions, lower revenues and earnings or delays in recovering capital expenditures.

●	OTP could be required to absorb a disproportionate share of costs for investments in transmission infrastructure required to provide independent power producers access to the transmission grid. These costs may not be recoverable through a transmission tariff and could result in reduced returns on invested capital and/or increased rates to OTP's retail electric customers.

●	OTP’s electric generating facilities are subject to operational risks that could result in unscheduled plant outages, unanticipated operation and maintenance expenses and increased power purchase costs.

●	Wholesale sales of electricity from excess generation could be affected by reductions in coal shipments to the Big Stone and Hoot Lake plants due to supply constraints or rail transportation problems beyond our control.

●	Changes to regulation of generating plant emissions, including but not limited to carbon dioxide (CO 2 ) emissions, could affect OTP’s operating costs and the costs of supplying electricity to its customers.

●	The U.S. wind industry is reliant on tax and other economic incentives and political and governmental policies. A significant change in these incentives and policies could negatively impact our results of operations and growth.

●	Our wind tower manufacturing business is substantially dependent on a few significant customers.

●	Prolonged periods of low utilization of DMI’s wind tower production plants, due to a continuing softening of demand for its product, could cause DMI to idle certain facilities. Should this softened demand for wind towers continue, these events may result in impairment charges on certain of DMI’s facilities if future cash flow estimates, based on information available to management at the time, indicate that the plants carrying values may not be recoverable or, if any plant assets are sold below their carrying values, significant losses may be incurred.

●	Competition from foreign and domestic manufacturers, cost management in a fixed price contract project environment, the price and availability of raw materials and diesel fuel, the ability of suppliers to deliver materials at contracted prices, fluctuations in foreign currency exchange rates and general economic conditions could affect the revenues and earnings of our wind energy and manufacturing businesses.

●	A significant failure or an inability to properly bid or perform on projects by our wind energy, construction or manufacturing businesses could lead to adverse financial results and could lead to the possibility of delay or liquidated damages.

●	Our Plastics segment is highly dependent on a limited number of vendors for PVC resin, many of which are located in the Gulf Coast regions, and a limited supply of resin. The loss of a key vendor, or an interruption or delay in the supply of PVC resin, could result in reduced sales or increased costs for this segment.

●	Our plastic pipe companies compete against a large number of other manufacturers of PVC pipe and manufacturers of alternative products. Customers may not distinguish the pipe companies’ products from those of its competitors.

●	Reductions in PVC resin prices can negatively impact PVC pipe prices, profit margins on PVC pipe sales and the value of PVC pipe held in inventory.

●	Changes in the rates or method of third-party reimbursements for diagnostic imaging services could result in reduced demand for those services or create downward pricing pressure, which would decrease revenues and earnings for our Health Services segment.

●	Our health services businesses may be unable to continue to maintain agreements with Philips Medical from which the businesses derive significant revenues from the sale and service of Philips Medical diagnostic imaging equipment.

●	Technological change in the diagnostic imaging industry could reduce the demand for diagnostic imaging services and require our health services operations to incur significant costs to upgrade its equipment.

●	Actions by regulators of our health services operations could result in monetary penalties or restrictions in our health services operations.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

At June 30, 2011 we had exposure to market risk associated with interest rates because we had $16.1 million in short-term debt outstanding subject to variable interest rates that are indexed to LIBOR plus 3.25% under our $200 million revolving credit facility and $16.7 million in short-term debt outstanding subject to variable interest rates that are indexed to LIBOR plus 1.5% under OTP’s $170 million revolving credit facility. At June 30, 2011 we had exposure to changes in foreign currency exchange rates. DMI has market risk related to changes in foreign currency exchange rates at its plant in Ft. Erie, Ontario because the plant pays its operating expenses in Canadian dollars.

The majority of our consolidated long-term debt has fixed interest rates. The interest rate on variable rate long-term debt is reset on a periodic basis reflecting current market conditions. We manage our interest rate risk through the issuance of fixed-rate debt with varying maturities, through economic refunding of debt through optional refundings, limiting the amount of variable interest rate debt, and the utilization of short-term borrowings to allow flexibility in the timing and placement of long-term debt. As of June 30, 2011 we had $10.4 million of long-term debt subject to variable interest rates. Assuming no change in our financial structure, if variable interest rates were to average one percentage point higher or lower than the average variable rate on June 30, 2011, annualized interest expense and pre-tax earnings would change by approximately $104,000.

We have not used interest rate swaps to manage net exposure to interest rate changes related to our portfolio of borrowings. We maintain a ratio of fixed-rate debt to total debt within a certain range. It is our policy to enter into interest rate transactions and other financial instruments only to the extent considered necessary to meet our stated objectives. We do not enter into interest rate transactions for speculative or trading purposes.

DMI and the companies in our Manufacturing segment are exposed to market risk related to changes in commodity prices for steel, lumber, aluminum, cement and resin. The price and availability of these raw materials could affect the revenues and earnings of our Wind Energy and Manufacturing segments.

The plastics companies are exposed to market risk related to changes in commodity prices for polyvinyl chloride (PVC) resins, the raw material used to manufacture PVC pipe. The PVC pipe industry is highly sensitive to commodity raw material pricing volatility. Historically, when resin prices are rising or stable, sales volume has been higher and when resin prices are falling, sales volumes has been lower. Operating income may decline when the supply of PVC pipe increases faster than demand. Due to the commodity nature of PVC resin and the dynamic supply and demand factors worldwide, it is very difficult to predict gross margin percentages or to assume that historical trends will continue.

OTP has market, price and credit risk associated with forward contracts for the purchase and sale of electricity. As of June 30, 2011 OTP had recognized, on a pretax basis, $646,000 in net unrealized gains on open forward contracts for the purchase and sale of electricity. Due to the nature of electricity and the physical aspects of the electricity transmission system, unanticipated events affecting the transmission grid can cause transmission constraints that result in unanticipated gains or losses in the process of settling transactions.

The market prices used to value OTP’s forward contracts for the purchases and sales of electricity are determined by survey of counterparties or brokers used by OTP’s power services’ personnel responsible for contract pricing, as well as prices gathered from daily settlement prices published by the Intercontinental Exchange and CME Globex. For certain contracts, prices at illiquid trading points are based on a basis spread between that trading point and more liquid trading hub prices. These basis spreads are determined based on available market price information and the use of forward price curve models. The forward energy purchase and sales contracts that are marked to market as of June 30, 2011 are 89.4% offsetting in terms of volumes and delivery periods but not in terms of delivery points. The differential in forward prices at the different delivery locations currently results in a mark-to-market unrealized gain on OTP’s open forward contracts.

We have in place an energy risk management policy with a goal to manage, through the use of defined risk management practices, price risk and credit risk associated with wholesale power purchases and sales. Volumetric limits and loss limits are used to adequately manage the risks associated with our energy trading activities. Additionally, we have a Value at Risk (VaR) limit to further manage market price risk. There was price risk on open positions as of June 30, 2011 because the open purchases were not at the same delivery points as the open sales.

The following tables show the effect of marking to market forward contracts for the purchase and sale of electricity and the location and fair value amounts of the related derivatives reported on our consolidated balance sheets as of June 30, 2011 and December 31, 2010, and the change in our consolidated balance sheet position from December 31, 2010 to June 30, 2011:

The $646,000 in recognized but unrealized net gains on the forward energy and capacity purchases and sales marked to market on June 30, 2011 is expected to be realized on settlement as scheduled over the following periods in the amounts listed:

(in thousands)		3rd Quarter 2011				4th Quarter 2011				2012				Total
Net Gain		$	32			$	145			$	469			$	646

The following realized and unrealized net (losses)/gains on forward energy contracts are included in electric operating revenues on our consolidated statements of income:

	Three Months Ended					Six Months Ended
	June 30,					June 30,
(in thousands)	2011		2010			2011		2010
Net Gains (Losses) on Forward Electric Energy Contracts	$	139	$	(24	)	$	131	$	1,801

OTP has credit risk associated with the nonperformance or nonpayment by counterparties to its forward energy and capacity purchases and sales agreements. We have established guidelines and limits to manage credit risk associated with wholesale power and capacity purchases and sales. Specific limits are determined by a counterparty’s financial strength. OTP’s credit risk with its largest counterparty on delivered and marked-to-market forward contracts as of June 30, 2011 was $970,000. As of June 30, 2011 OTP had a net credit risk exposure of $1,732,000 from four counterparties with investment grade credit ratings. OTP had no exposure at June 30, 2011 to counterparties with credit ratings below investment grade. Counterparties with investment grade credit ratings have minimum credit ratings of BBB- (Standard & Poor’s), Baa3 (Moody’s) or BBB- (Fitch). The $1,732,000 credit risk exposure included net amounts due to OTP on receivables/payables from completed transactions billed and unbilled plus marked-to-market gains/losses on forward contracts for the purchase and sale of electricity scheduled for delivery after June 30, 2011. Individual counterparty exposures are offset according to legally enforceable netting arrangements.

Item 4. Controls and Procedures

Under the supervision and with the participation of the Company’s management, including the Chief Executive Officer and the Chief Financial Officer, the Company evaluated the effectiveness of the design and operation of its disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934 (the Exchange Act)) as of June 30, 2011, the end of the period covered by this report. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the Company’s disclosure controls and procedures were effective as of June 30, 2011.

During the fiscal quarter ended June 30, 2011, there were no changes in the Company’s internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

PART II . OTHER INFORMATION

Item 1. Legal Proceedings

The Company is the subject of various pending or threatened legal actions and proceedings in the ordinary course of its business. Such matters are subject to many uncertainties and to outcomes that are not predictable with assurance. The Company records a liability in its consolidated financial statements for costs related to claims, including future legal costs, settlements and judgments, where it has assessed that a loss is probable and an amount can be reasonably estimated. The Company believes the final resolution of currently pending or threatened legal actions and proceedings, either individually or in the aggregate, will not have a material adverse effect on the Company’s consolidated financial position, results of operations or cash flows.

Item 1A . Risk Factors

The Company is updating the risk factors set forth under Part I, Item 1A, “Risk Factors” on pages 32 through 39 of the Company’s Annual Report on Form 10-K for the year ended December 31, 2010 by replacing a risk factor related to its construction segment with a general risk factor that applies to several businesses owned by the Company, revising and adding risk factors related to the Company’s strategic growth plans, warranty claims and performance on contracts, and eliminating a risk factor related to its Food Ingredient Processing operations.

Revised Risk Factors:

Our plans to grow and realign our diversified business mix through capital projects, acquisitions and dispositions may not be successful, which could result in poor financial performance.

As part of our business strategy, we intend to increase capital expenditures in our existing businesses and realign our mix of diversified businesses through strategic acquisitions or dispositions. There are risks associated with capital expenditures including not being granted timely or full recovery of rate base additions in our regulated utility business and the inability to recover the cost of capital additions due to an economic downturn, lack of markets for new products, competition from producers of lower cost or alternative products, product defects or loss of customers. We may not be able to identify appropriate acquisition candidates or successfully negotiate, finance or integrate acquisitions. Future acquisitions could involve numerous risks including: difficulties in integrating the operations, services, products and personnel of the acquired business; and the potential loss of key employees, customers and suppliers of the acquired business. If we are unable to successfully manage these risks, we could face reductions in net income in future periods.

Our plans to grow and operate our nonelectric businesses could be limited by state law.

Our plans to grow and operate our nonelectric businesses could be adversely affected by legislation in one or more states that may attempt to limit the amount or level of diversification permitted in a holding company structure that includes a regulated utility company or affiliated nonelectric companies.

Competition from foreign and domestic manufacturers, cost management in a fixed price contract project environment, fluctuations in foreign currency exchange rates and general economic conditions could affect the revenues and earnings of our Wind Energy segment.

Prolonged periods of low utilization of DMI’s wind tower production plants, due to a continuing softening of demand for its product, could cause DMI to idle certain facilities. Should this softened demand for wind towers continue, these events may result in impairment charges on certain of DMI’s facilities if future cash flow estimates, based on information available to management at the time, indicate that the plants carrying values may not be recoverable or, if any plant assets are sold below their carrying values, significant losses may be incurred.

New Risk Factors:

Significant warranty claims in excess of amounts normally reserved for such items and remediation costs could adversely affect our results of operations and financial condition.

Depending on the specific product or service, we provide certain warranty terms against manufacturing defects and certain materials. We reserve for warranty claims based on industry experience and estimates made by management. For some of our products we have limited history to base our warranty estimate on. Our assumptions could be materially different from any actual claim and could exceed reserve balances.

Expenses associated with remediation activities in the wind energy segment could be substantial. The potential exists for multiple claims based on one defect repeated throughout the production process or for claims where the cost to repair or replace the defective part is highly disproportionate to the original cost of the part. If we are required to cover remediation expenses in addition to our regular warranty coverage, we could be required to accrue additional expenses and experience additional unplanned cash expenditures which could adversely affect our consolidated results of operations and financial condition.

A significant failure or an inability to properly bid or perform on projects by our wind energy, construction or manufacturing businesses could lead to adverse financial results and could lead to the possibility of delay or liquidated damages.

The profitability and success of our wind energy, construction or manufacturing companies require us to identify, estimate and timely bid on profitable projects. The quantity and quality of projects up for bids at any time is uncertain. Additionally, once a project is awarded, we must be able to perform within cost estimates that were set when the bid was submitted and accepted. A significant failure or an inability to properly bid or perform on projects could lead to adverse financial results and could lead to the possibility of delay or liquidated damages.

Eliminated Risk Factors:

Our construction companies may be unable to properly bid and perform on project s.

The profitability and success of our construction companies require us to identify, estimate and timely bid on profitable projects. The quantity and quality of projects up for bids at any time is uncertain. Additionally, once a project is awarded, we must be able to perform within cost estimates that were set when the bid was submitted and accepted. A significant failure or an inability to properly bid or perform on projects could lead to adverse financial results for our construction companies.

Our company that processes dehydrated potato flakes, flour and granules, IPH, competes in a highly competitive market and is dependent on adequate sources of potatoes for processing.

The market for processed, dehydrated potato flakes, flour and granules is highly competitive. The profitability and success of our potato processing company is dependent on superior product quality, competitive product pricing, strong customer relationships, raw material costs, fuel prices and availability and customer demand for finished goods. In most product categories, our company competes with numerous manufacturers of varying sizes in the United States.

The principal raw material used by IPH is washed process-grade potatoes from growers and potato fresh packing operations. These potatoes are unsuitable for use in other markets due to imperfections. They are not subject to the United States Department of Agriculture’s general requirements and expectations for size, shape or color. While our food ingredient processing company has processing capabilities in three geographically distinct growing regions, there can be no assurance it will be able to obtain raw materials due to poor growing conditions, a loss of key suppliers, loss of potato production acres to other crops, and other factors. A loss or shortage of raw materials or the necessity of paying much higher prices for raw materials or fuel could adversely affect the financial performance of this company. Fluctuations in foreign currency exchange rates could have a negative impact on our potato processing company’s net income and competitive position because approximately 18% of IPH sales in 2010 and approximately 16% of IPH sales in 2009 were outside the United States and the Canadian plant pays its operating expenses in Canadian dollars.

Item 2 . Unregistered Sales of Equity Securities and Use of Proceeds

The Company does not have a publicly announced stock repurchase program. The following table shows common shares that were surrendered to the Company by employees to pay taxes in connection with shares issued for incentive awards under the Company's 1999 Stock Incentive Plan:
