1. SummaryUse of Significant Accounting Policies

Revenue Recognition

Due to the diverse business operations of the Company, recognition of revenue from contracts with customers depends on the product produced and sold or service performed. The Company recognizes revenue from contracts with customers at prices that are fixed or determinable as evidenced by an agreement with the customer, when the Company has met its performance obligation under the contract and it is probable that the Company will collect the amount to which it is entitled in exchange for the goods or services transferred or to be transferred to the customer. Depending on the product produced and sold or service performed and the terms of the agreement with the customer, the Company recognizes revenue either over time, in the case of delivery or transmission of electricity or related services or the production and storage of certain custom-made products, or at a point in time for the delivery of standardized products and other products made to the customer’s specifications where the terms of the contract require transfer of the completed product. Provisions for sales returns, early payment terms discounts, volume-based variable pricing incentives and warranty costs are recorded as reductions to revenue at the time revenue is recognized based on customer history, historical information and current trends.

In addition to recognizing revenue from contracts with customers under Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) Topic 606,Revenue from Contracts with Customers (ASC 606), the Company also records adjustments to Electric segment revenues for amounts subject to future collection under alternative revenue programs (ARPs) as defined in ASC Topic 980,Regulated Operations (ASC 980). The ARP revenue adjustments are recorded on the basis of recoverable costs incurred and returns earned under rate riders on a separate line on the face of the Company’s consolidated statements of income as they do not meet the criteria to be classified as revenue from contracts with customers.

Electric Segment Revenues—In the Electric segment, the Company recognizes revenue in two categories: (1) revenues from contracts with customers and (2) adjustments to revenues for amounts collectible under ARPs.

Most Electric segment revenues are earned from the generation, transmission and sale of electricity to retail customers at rates approved by regulatory commissions in the states where Otter Tail Power Company (OTP) provides service. OTP also earns revenue from the transmission of electricity for others over the transmission assets it owns separately, or jointly with other transmission service providers, under rate tariffs established by the independent transmission system operator and approved by the Federal Energy Regulatory Commission (FERC). A third source of revenue for OTP comes from the generation and sale of electricity to wholesale customers at contract or market rates. Revenues from all these sources meet the criteria to be classified as revenue from contracts with customers and are recognized over time as energy is delivered or transmitted. Revenue is recognizedEstimates

We use estimates based on the metered quantity of electricity delivered or transmitted atbest information available in recording transactions and balances resulting from business operations. As better information becomes available (or actual amounts are known), the applicable rates. For electricity delivered and consumed after a meter is read but prior to the end of the reporting period, OTP records revenue and an unbilled receivable based onrecorded estimates of the kilowatt-hours (kwh) of energy delivered to the customer.

ARPs provide for adjustments to rates outside of a general rate case proceeding, usually as a surcharge applied to future billings typically through the use of rate riders subject to periodic adjustments, to encourage or incentivize investments in certain areas such as conservation, renewable energy, pollution reduction or control, improved infrastructure of the transmission grid or other programs that provide benefits to the general public under public policy, laws or regulations. ARP riders generally provide for the recovery of specified costs and investments and include an incentive component to provide the regulated utility with a return on amounts invested.

OTP has recovered costs and earned incentives or returns on investments subject to recovery under several ARP rate riders, including:

In Minnesota: Transmission Cost Recovery (TCR), Environmental Cost Recovery (ECR), Renewable Resource Adjustment (RRA), Energy Intensive Trade Exposed and Conservation Improvement Program riders.

In North Dakota: TCR, ECR, Renewable Resource Cost Recovery and Generation Cost Recovery (GCR) riders.

In South Dakota: TCR, ECR, Phase-In Rate Plan and Energy Efficiency Plan (conservation) riders.

8

OTP accrues ARP revenue based on costs incurred, investments made and returns on those investments that qualify for recovery through established riders. Amounts billed under riders in effect at the time of the billing are included in revenues from contracts with customers net of amounts billed that are subject to refund through future rider adjustments. Amounts accrued and subject to recovery through future rider rate updates and adjustments are reported as changes in accrued revenues under ARPs on a separate line in the revenue section of the Company’s consolidated statement of income. See table in note 3 for total revenues billed and accrued under ARP riders for the three- and six-month periods ended June 30, 2020 and 2019.

Manufacturing Segment Revenues—Companies in the Manufacturing segment, BTD Manufacturing, Inc. (BTD) and T.O. Plastics, Inc. (T.O. Plastics), earn revenue predominantly from the production and delivery of custom-made or standardized parts to customers across several industries. BTD also earns revenue from the production and sale of tools and dies to other manufacturers. For the production and delivery of standardized products and other products made to customer specifications where the terms of the contract require transfer of the completed product, therevised. Consequently, operating company has met its performance obligation and recognizes revenue at the point in time when the product is shipped. For revenue recognized on products when shipped, the operating companies have no further obligation to provide services related to such products. The shipping terms used in these instances are FOB shipping point.

Plastics Segment Revenues—Companies in our Plastics segment earn revenue predominantly from the sale and delivery of standardized polyvinyl chloride (PVC) pipe products produced at their manufacturing facilities. Revenue from the sale of these products is recognized at the point in time when the product is shipped based on prices agreed to in a purchase order. For revenue recognized on shipped products, there is no further obligation to provide services related to such products. The shipping terms used in these instances are FOB shipping point. The Plastics segment has one customer for which it produces and stores a product made to the customer’s specifications and design under a build and hold agreement. For sales to this customer, the operating company recognizes revenue as the custom-made product is produced, adjusting the amount of revenue for volume rebate variable pricing considerations the operating company expects the customer will earn and applicable early payment discounts the company expects the customer will take. Ownership of the pipe transfers to the customer prior to delivery and the operating company is paid a negotiated fee for storage of the pipe.

See operating revenue table in note 2 for a disaggregation of the Company’s revenues by business segment for the three- and six-month periods ended June 30, 2020 and 2019.

Agreements Subject to Legally Enforceable Netting Arrangements

OTP has certain derivative contracts that are designated as normal purchases. Individual counterparty exposures for these contractsresults can be offset accordingaffected by revisions to legally enforceable netting arrangements. The Company does not offset assetsprior accounting estimates.

2. Segment Information
We classify our business into 3 segments, Electric, Manufacturing and liabilities under legally enforceable netting arrangements on the face of its consolidated balance sheet. 

Fair Value Measurements

The Company follows ASC Topic 820,Fair Value Measurements and Disclosures (ASC 820), for recurring fair value measurements. ASC 820 provides a single definition of fair value, requires enhanced disclosures about assets and liabilities measured at fair value and establishes a hierarchical 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.

9

The following tables present, for each of the hierarchy levels, the Company’s assets and liabilities that are measured at fair value on a recurring basis as of June 30, 2020 and December 31, 2019:

The level 2 fair values for Government-Backed and Government-Sponsored Enterprises’ and Corporate Debt Securities Held by the Company’s Captive Insurance Company are determined on the basis of valuations provided by a third-party pricing service which utilizes industry accepted valuation models and observable market inputs to determine valuation. Some valuations or model inputs used by the pricing service may be based on broker quotes.

Coyote Station Lignite Supply Agreement – Variable Interest Entity

In October 2012 the Coyote Station owners, including OTP, entered into a lignite sales agreement (LSA) with Coyote Creek Mining Company, L.L.C. (CCMC), a subsidiary of The North American Coal Corporation, for the purchase of lignite coal to meet the coal supply requirements of Coyote Station for the period beginning in May 2016 and ending in December 2040. The price per ton paid by the Coyote Station owners under the LSA reflects the cost of production, along with an agreed profit and capital charge. CCMC was formed for the purpose of mining coal to meet the coal fuel supply requirements of Coyote Station from May 2016 through December 2040 and, based on the terms of the LSA, is considered a variable interest entity (VIE) due to the transfer of all operating and economic risk to the Coyote Station owners, as the agreement is structured so that the price of the coal would cover all costs of operations as well as future reclamation costs. The Coyote Station owners are required to buy certain assets of CCMC at book value should they terminate the contract prior to the end of the contract term and are providing a guarantee of the value of the equity of CCMC because the Coyote Station owners are required to buy the membership interests of CCMC at the end of the contract term at equity value. No single owner of Coyote Station owns a majority interest in Coyote Station or has the power to direct the activities that most significantly impact CCMC. Therefore, none of the owners individually, including OTP, is considered a primary beneficiary of the VIE and the Company is not required to include CCMC in its consolidated financial statements.

If the LSA terminates prior to the expiration of its term or the production period terminates prior to December 31, 2040 and the Coyote Station owners purchase all of the outstanding membership interests of CCMC, the owners will satisfy (or if permitted by CCMC’s applicable lender assume) all of CCMC’s obligations owed to CCMC’s lenders under its loans and leases. The Coyote Station owners have limited rights to assign their rights and obligations under the LSA without the consent of CCMC’s lenders during any period in which CCMC’s obligations to its lenders remain outstanding. In the event the contract is terminated prior to the end of the term due to certain events, OTP’s maximum exposure to additional costs, as a result of its involvement with CCMC, and potential impairment loss if recovery of those costs is denied by regulatory authorities, could be as high as approximately $50.0 million, OTP’s 35% share of CCMC’s unrecovered costs as of June 30, 2020.

New Accounting Standards Adopted

ASU 2016-13—In June 2016 the FASB issued Accounting Standards Update (ASU) No.2016-13,Financial Instruments—Credit Losses (Topic 326) (ASC 326), which changes how entities account for credit losses on receivables and certain other assets effective for interim and annual periods beginning on or after December 31, 2019. The guidance requires use of a current expected credit loss model, which may result in earlier recognition of credit losses than under previous accounting standards. The Company adopted ASC 326 in the first quarter of 2020. Adoption of the new standard did not have a material impact on the Company’s consolidated financial statements, and the Company did not record a cumulative effect adjustment to retained earnings on adoption.

Accounting Policy

Trade account and unbilled receivables reflected in the Company’s consolidated balance sheets represent the net amounts expected to be collected. An allowance for credit losses is established based on expected losses. Expected losses are estimated by reviewing individual accounts, considering aging, financial condition of the debtor for certain accounts, recent payment history, current and forecasted economic conditions and other relevant factors.

Allowance for Credit Losses

ASU 2018-15—In August 2018 the FASB issued ASU No.2018-15,Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40), which amends ASC 350-40, Internal-Use Software, to address a customer's accounting for implementation costs incurred in a cloud computing arrangement that is a service contract. The amendments in ASU 2018-15 align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). Accordingly, the amendments in ASU 2018-15 require an entity (customer) in a hosting arrangement that is a service contract to follow the guidance in ASC 350-40 to determine which implementation costs to capitalize as an asset related to the service contract and which costs to expense. The amendments in ASU 2018-15 also require the entity to present the expense related to the capitalized implementation costs in the same line item in the statement of income as the fees associated with the hosting element (service) of the arrangement and classify payments for capitalized implementation costs in the statement of cash flows in the same manner as payments made for fees associated with the hosting element. The entity is also required to present the capitalized implementation costs in the statement of financial position in the same line item that a prepayment for the fees of the associated hosting arrangement would be presented. The amendments in ASU 2018-15 were effective for interim and annual periods beginning on or after December 15, 2019 with early adoption permitted in any interim period. The Company adopted the amendments in ASU 2018-15 in the first quarter of 2020. There was no impact to its consolidated financial statements on adoption, but the Company will begin capitalizing implementation costs incurred in cloud computing arrangements post-adoption.

Also on November 16, 2016, OTP entered into a Turnkey Engineering, Procurement and Construction Services Agreement (the TEPC Agreement) with EDF-RE US Development, LLC (EDF-USD) pursuant to which EDF-USD will develop, design, procure, construct, interconnect, test and commission the wind farm with a targeted completion date in 2020 for consideration of approximately $200.5 million, subject to certain adjustments, payable following the closing of the Purchase Agreement in installments in connection with certain project construction milestones. In connection with action by the FERC, OTP and EDF-US agreed, in the First Amendment to the Purchase Agreement and the TEPC Agreement dated June 11,2019, to change the purchase price to $37.7 million andhas commitments to make a related reallocation of responsibility for interconnection costs and liabilities. On July 16, 2019 OTP closed on the purchase of substantially all of the development assets and assumed certain specified liabilities from EDF related to Merricourt pursuant to the Purchase Agreement, as amended, for a purchase price of approximately $37.7 million, subject to certain adjustments, and issued the notice to EDF-USD to begin construction in August 2019. The agreements contain customary representations, warranties, covenants and indemnities for this type of transaction. The Merricourt generator interconnection agreement with MISO was approved by the future payments under land easements extending into 2050.

Contingencies
FERC in April 2019.

OTP is earning a return in all three states served by OTP on amounts invested in Merricourt while the project is under construction. Returns are recovered in Minnesota and North Dakota through RRA riders and in South Dakota through the Phase-In Rate Plan rider. As of June 30, 2020, OTP had capitalized approximately $131.7 million in project costs and allowance for funds used during construction (AFUDC) associated with Merricourt. While construction on site continues, OTP has received Notices of Force Majeure from EDF-USD claiming rights to an extension of guaranteed project completion dates and adjustments to the consideration agreed upon in the TEPC Agreement due to COVID-19 impacts. While details regarding these claims and the related impacts to the project remain uncertain, OTP currently expects Merricourt to be completed before December 31, 2020.

ROE.Astoria Station—OTP is constructing this 245 MW simple-cycle natural gas-fired combustion turbine generation facility near Astoria, South Dakota as part of its plan to reliably meet customers’ electric needs, replace expiring capacity purchase agreements and prepare for the planned retirement of its Hoot Lake Plant in 2021. A final order granting an Advanced Determination of Prudence for Astoria Station was issued by the NDPSC on November 3, 2017, subject to certain qualifications and compliance obligations. On August 3, 2018 the SDPUC issued an order granting a site permit for Astoria Station. In a September 26, 2018 hearing the NDPSC established a GCR rider for future recovery of costs incurred for Astoria Station. On March 6, 2019 the SDPUC issued an order approving a settlement that allows a phase-in rider which includes recovery of Astoria Station costs. The interconnection agreement for Astoria Station was executed by MISO in December 2018 and accepted by the FERC in January 2019. Site preparation and excavation began in May 2019, and construction is occurring on the site. As of June 30, 2020, OTP had capitalized approximately $108.0 million in project costs and AFUDC associated with Astoria Station. OTP currently expects this project will be completed in late 2020 or early 2021.

General Rates

Minnesota—The MPUC rendered its final decision in OTP’s 2016 general rate case in March 2017 and issued its written order on May 1, 2017. Pursuant to the order, OTP’s allowed rate of return on rate base is 7.5056% and its allowed rate of return on equity (ROE) is 9.41%.

The MPUC’s order also included: (1) the determination that all costs (including FERC allocated costs and revenues) of the Big Stone South–Brookings and Big Stone South–Ellendale MVPs will be included in the Minnesota TCR rider and jurisdictionally allocated to OTP’s Minnesota customers (see discussion under Minnesota Transmission Cost Recovery Rider below), and (2) approval of OTP’s proposal to transition rate base, expenses and revenues from ECR and TCR riders to base rate recovery, which occurred when final rates were implemented on November 1, 2017. Certain MISO expenses and revenues remain in the TCR rider to allow for the ongoing refund or recovery of these variable revenues and costs.

North Dakota—On March 23, 2018 OTP made a supplemental filing to its initial request for a rate review, reducing its request for an annual revenue increase from $13.1 million to $7.1 million, a 4.8% annual increase. The $6.0 million decrease included $4.8 million related to tax reform and $1.2 million related to other updates.

In a September 26, 2018 hearing the NDPSC approved an overall annual revenue increase of $4.6 million (3.1%) and a ROE of 9.77% on a 52.5% equity capital structure. The NDPSC’s approval established a GCR rider for future recovery of costs incurred for Astoria Station. The net revenue increase reflected a reduction in income tax recovery requirements related to the 2017 Tax Cuts and Jobs Act (TCJA) and decreases in rider revenue recovery requirements. Final rates were effective February 1,2019, with refunds of excess revenues collected under interim rates applied to customers’ April 2019 bills, including $0.8 million for amounts collected reflecting the higher tax rates under interim rates in effect in January and February 2018.

South Dakota—On April 20, 2018 OTP filed a request with the SDPUC to increase non-fuel rates in South Dakota by approximately $3.3 million annually, or 10.1%, as the first step in a two-step request. Interim rates were effective October 18,2018. The second step in the request was an additional 1.7% revenue increase to recover costs for Merricourt when the wind generation facility goes into service. The SDPUC approved a partial settlement on March 1, 2019 on all issues of the rate case except ROE. The partial settlement included approval of a phase-in plan to provide for a return on amounts invested in Astoria Station and Merricourt, which addressed the second step of the request for increased rates in South Dakota. The partial settlement also included a moratorium on filing another general rate case in South Dakota until the new generation projects have been in service for a year. The partial settlement also allowed OTP to retain the impact of lower tax rates related to the TCJA from January 1, 2018 through October 17,2018 resulting in the reversal of an accrued refund liability and recognition of $1.0 million in revenue in the first quarter of 2019. The SDPUC approved the ROE portion of the rate case on May 14, 2019 and pursuant to the SDPUC’s May 30, 2019 order, OTP’s allowed ROE was set at 8.75%, resulting in an annual revenue increase of approximately $2.2 million. Final rates went into effect August 1, 2019. An interim rate refund for the lower ROE going back to October 18, 2018 was applied to South Dakota customers’ October 2019 bills.

On July 9, 2019 the SDPUC approved a stipulation agreement entered into by OTP with SDPUC staff. The revenue requirement stated in the SDPUC’s final order dated May 30, 2019 understated the amount of OTP's South Dakota share of electric transmission plant in service, resulting in an annual revenue requirement shortfall of approximately $341,000. To address the shortfall, the parties agreed that OTP would file an update to its South Dakota TCR rider. OTP was authorized full recovery of the transmission rate base correction reflected in the TCR rider tracker beginning as of the first date of interim rates, October 18, 2018, with the TCR rider rate update going into effect on October 1, 2019.

To ensure rates are appropriately set under the stipulation, the parties agreed to establish an earnings sharing mechanism to share with customers any weather-normalized earnings above the authorized ROE of 8.75%. OTP's annual weather-normalized earnings are reported each year by June 1 in its jurisdictional annual report, which will be used to determine the earnings level for purposes of calculating any refund. The earnings sharing mechanism requires that OTP will refund to customers 50% of any weather-normalized revenue that corresponds to the earnings in excess of its authorized ROE, up to a maximum of 9.50% ROE for a particular year. OTP will refund 100% of any earnings above 9.50% each year. In the event a refund is due under this provision, OTP will notify the SDPUC of the refund amount and plan for crediting customers within 30 days of filing its South Dakota jurisdictional annual report.

Rate Riders

In addition to general rates, OTP has several rate riders in place in each of its state jurisdictional service areas. These rate riders are designed to recover expenses, costs and returns on rate base investments not currently being recovered in base, or general, rates. In addition to fuel cost recovery riders in each state, OTP has recovered costs and earned incentives or returns on investments subject to recovery under several rate riders, including:

In Minnesota: Transmission Cost Recovery (TCR), Environmental Cost Recovery (ECR), Renewable Resource Adjustment (RRA), Energy Intensive Trade Exposed and Conservation Improvement Program riders.

In North Dakota: TCR, ECR, Renewable Resource Cost Recovery and Generation Cost Recovery (GCR) riders.

In South Dakota: TCR, ECR, Phase-In Rate Plan and Energy Efficiency Plan (conservation) riders.

Following is a brief summary of recent proceedings of riders in place in each state served by OTP, followed by tables showing revenues recorded under rate riders for the three- and six-month periods ended June 30, 2020 and June 30, 2019 and a listing of rate rider updates impacting revenues in 2020 and 2019. Additional information and background on these rate riders is provided in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019.

Minnesota

Minnesota Conservation Improvement Programs (MNCIP)—On May 1, 2020 OTP filed a request for approval of its 2019 energy savings, recovery of $2.7 million in accrued financial incentives and recovery of 2019 program costs not included in base rates.

Transmission Cost Recovery Rider—In OTP’s 2016 general rate case order issued on May 1, 2017, the MPUC ordered OTP to include, in the TCR rider retail rate base, Minnesota’s jurisdictional share of OTP’s investment in the Big Stone South–Brookings and Big Stone South–Ellendale Multi-Value Projects (MVPs) and all revenues received from other utilities under MISO’s tariffed rates as a credit in its TCR revenue requirement calculations. In doing so, the MPUC’s order diverted interstate wholesale revenues that have been approved by the FERC to offset FERC-approved expenses, effectively reducing OTP’s recovery of those FERC-approved expense levels. The MPUC-ordered treatment resulted in the projects being treated as retail investments for Minnesota retail ratemaking purposes. Because the FERC’s revenue requirements and authorized returns vary from the MPUC revenue requirements and authorized returns for the project investments over the lives of the projects, the impact of this decision can vary over time and be dependent on the differences between the revenue requirements and returns in the two jurisdictions at any given time. On August 18, 2017 OTP filed an appeal of the MPUC general rate case order with the Minnesota Court of Appeals to contest the portion of the order requiring OTP to jurisdictionally allocate costs of the FERC MVP transmission projects in the TCR rider.

On June 11, 2018 the Minnesota Court of Appeals reversed the MPUC’s order related to the inclusion of Minnesota’s jurisdictional share of OTP’s investment in the Big Stone South–Brookings and Big Stone South–Ellendale MVPs and all revenues received from other utilities under MISO’s tariffed rates as a credit in OTP Minnesota TCR revenue requirement calculations. On July 11, 2018 the MPUC filed a petition for review of the MVP decision to the Minnesota Supreme Court, which granted review of the Minnesota Court of Appeals decision.

On November 30, 2018 OTP filed its annual update and supplemental filing to the Minnesota TCR rider. In this filing two scenarios were submitted based on whether the Minnesota Supreme Court affirmed the original decision by the Minnesota Court of Appeals to exclude the MVP projects from the TCR rider or overturned the Minnesota Court of Appeals decision and includes the two MVP projects in the TCR rider. In addition, on April 1, 2019, the MNDOC filed comments in OTP’s TCR rider docket, opposing OTP’s proposal for TCR rider recovery of these costs. The Minnesota Supreme Court issued its opinion on April 22,2020, concluding that the MPUC lacked authority to amend an existing transmission cost-recovery rider approved under Minnesota state law to include the costs and revenues associated with the Big Stone South–Brookings and Big Stone South–Ellendale MVPs and affirming the decision of the Minnesota Court of Appeals.

17

On May 7, 2020 OTP filed reply comments in the docket within 15 days of the Minnesota Supreme Court ruling as required by the MPUC. OTP filed updated revenue requirements excluding the Brookings and Big Stone–Ellendale projects and including three projects previously requested in the Minnesota TCR rider eligibility petition. OTP requested new rates be implemented January 1, 2021 with the three new projects deemed eligible for TCR rider recovery effective January 1, 2020. OTP also requested one-half of the December 2020 tracker balance of $13.4 million be included in the January 1, 2021 revenue requirement with the remainder included in the next annual update. OTP also requested a carrying charge be included as of January 1, 2021. On June 4, 2020 the MPUC filed a Notice of Combined and Extended Comment Period for both the Minnesota TCR rider and TCR rider eligibility filing with the comment period closing on July 6, 2020 and the reply comment period closing on July 21, 2020. In the MNDOC's comments regarding eligibility for recovery of investments in the three new projects through the Minnesota TCR rider, the MNDOC recommended the MPUC reject OTP’s petition for inclusion of the three projects. In the matter of OTP’s petition for approval of a TCR annual adjustment, at the request of the MNDOC the MPUC extended the deadlines for filing initial and reply comments to August 14,2020 and August 24, 2020, respectively. The estimated amount of higher MISO ROE revenues credited to Minnesota customers through the TCR rider through June 30, 2020, which OTP is now seeking recovery of through its Minnesota TCR rider update request, is approximately $2.6 million.

Renewable Resource Adjustment—On June 21, 2019 OTP filed its annual update to the Minnesota RRA requesting approval for recovery of the difference in PTCs in base rates and the actual PTCs generated, as well as recovery of Merricourt. On December 19, 2019 the MPUC approved a revised request which included changes related to Merricourt capitalized costs.

Fuel and Purchased Power Costs Recovery—In a December 2017 order, the MPUC adopted a program to implement certain procedural reforms to Minnesota utilities’ automatic fuel adjustment clause (FAC) for fuel and purchased power cost recovery. With this order, the method of accounting for all Minnesota electric utilities changed to a monthly budgeted, forward-looking FAC with annual prudence review and true-up to actual allowed costs. On October 31, 2019 the MPUC approved the forecasted monthly fuel cost rates submitted by OTP for 2020 and the rates became effective on January 1, 2020. This mechanism could result in reductions in Electric segment operating income margins, increase variability in consolidated net income in future periods if costs per kwh vary from forecasted costs per kwh, and cause an increase in working capital and short-term borrowings in the event recovery of all or a portion of excess costs is delayed or denied by the MPUC.

North Dakota

Renewable Resource Adjustment—On December 31, 2019 OTP filed its annual update to the North Dakota RRA requesting approval for recovery of the difference in PTCs in base rates and the actual PTCs generated, as well as a return on Merricourt costs incurred while under construction. This update also included a credit for the remaining unrefunded credit balance in the North Dakota ECR rider tracker on November 30, 2019. On February 25, 2020 OTP filed a revised request which was approved by the NDPSC on March 18, 2020. Part of the NDPSC’s approval included adopting a levelized utilization of PTCs from the Merricourt project over the expected 25-year life of the project for rate-making purposes. PTCs on prior projects were passed back to customers through lower rates as they were generated over 10 years.

Generation Cost Recovery Rider—On May 15, 2019 the NDPSC approved OTP’s request to establish an initial GCR rider rate for recovery of OTP’s North Dakota jurisdictional share of the revenue requirements on its investment in Astoria Station, effective on bills rendered after July 1, 2019. On June 10, 2020 the NDPSC approved the 2020 annual update request with an effective date of July 1, 2020.

South Dakota

Phase-In Rate Plan Rider—On May 31, 2019 OTP petitioned the SDPUC for approval of its initial rate for the Phase-In Rate Plan Rider as described in OTP’s most recent South Dakota general rate case settlement stipulation and was approved by the SDPUC’s order in that rate case. The petition was OTP’s initial filing for the rider to recover OTP’s South Dakota share of actual and forecasted costs for Astoria Station and Merricourt, and to refund forecasted net benefits associated with additional load growth in the Lake Norden area. On August 21, 2019 the SDPUC approved OTP’s supplemental filing for its South Dakota Phase-In Rate Plan Rider effective September 1, 2019. On June 1, 2020 OTP filed its first annual update request to the rider with a proposed effective date of September 1, 2020.

FERC

Wholesale power sales and transmission rates are subject to the jurisdiction of the FERC under the Federal Power Act of 1935 (Federal Power Act). The FERC is an independent agency with jurisdiction over rates for wholesale electricity sales, transmission and sale of electric energy in interstate commerce, interconnection of facilities, and accounting policies and practices. Filed rates are effective after a suspension period, subject to ultimate approval by the FERC.

MVPs—MVPs are designed to enable the MISO region to comply with energy policy mandates and to address reliability and economic issues affecting multiple transmission zones within the MISO region. The cost allocation is designed to ensure that the costs of transmission projects with regional benefits are properly assigned to those who benefit from the MVP.

ROE—In November 2013 and February 2015, customers filed complaints with FERC seeking to reduce the ROE component of the transmission rates that MISO transmission owners, including OTP, may collect under the MISO tariff. OTP hastariff rate. FERC's most recent order, issued on November 19, 2020, adopted a revised ROE methodology and set the base ROE at 10.02% (10.52% with an adder) effective for the fifteen-month period from November 2013 to February 2015 and on a prospective basis beginning in September 2016. The order also dismissed any complaints covering the period from February 2015 to May 2016. The November 2020 opinion is subject to judicial review. We have deferred recognition and recorded a refund liability of $2.9$3.7 million as of June 30, 2020 as a resultMarch 31, 2021. This refund liability reflects our best estimate of the disputed ROE awaiting FERC action. The provision includes:

a $0.1 million refund for the first complaint period of November 2013 to February 2015 resulting from the potential reduction of the base ROE from 10.32%.

a $1.5 million refund related to the second complaint period of February 2015 to May 2016 resulting from a potential reduction in base ROE from 12.38%.

a $1.3 million refund for the period from September 2016 through June 2020 resulting from a potential reduction in base ROE from 10.82%.

Various FERC orders have been made that remain under appeal. All or some of the current liability will be refundedrequired refunds to customers once all regulatory and judicial proceedings are finalized.

Regional Haze Rule (RHR). The RHR was adopted in an effort to improve visibility in national parks and wilderness areas. The RHR requires states, in coordination with the EPA and other governmental agencies, to develop and implement plans to achieve natural visibility conditions. The second RHR implementation period covers the years 2018-2028, with state implementation plans targeted for submission to the EPA by July 31, 2021. States are required to assess reasonable progress with the RHR and determine what additional emission reductions are appropriate, if any.
Coyote Station, OTP's jointly owned coal-fired power plant in North Dakota, is subject to assessment in the second implementation period under the North Dakota state implementation plan. We cannot predict with certainty the impact the state implementation plan may have on our business until the plan is finalized and adopted. However, significant emission control investments could be required, and the recovery of such costs from customers would require regulatory approval. Alternatively, investments in emission control equipment may prove to be uneconomic and result in a required early retirement of, or reversed and recognized as revenue depending on various factors including MISO’s determinationthe sale of refund amounts and FERC’s final determination of the reasonableness of base ROE over various periods.

4. Regulatory Assets and Liabilities

As a regulated entity, OTP accounts forour interest in, Coyote Station. We cannot estimate the financial effects such a retirement or sale may have on our consolidated operating results, financial position or cash flows, but such amounts could be material and the recovery of regulationsuch costs from customers would be subject to regulatory approval.

Other Contingencies. We are party to litigation and regulatory enforcement matters arising in accordance with ASC 980. This accounting standard allowsthe normal course of business. We regularly analyze relevant information and, as necessary, estimate and record accrued liabilities for legal, regulatory enforcement and other matters in which a loss is probable of occurring and can be reasonably estimated. We believe the effect on our consolidated operating results, financial position and cash flows, if any, for the recordingdisposition of a regulatory asset or liability for costs thatall matters pending as of March 31, 2021, other than those relating to the RHR, will not be collected or refunded in the future as required under regulation. Additionally, ASC 980-605-25 provides for the recognition of revenues authorized for recovery outside of a general rate case under alternative revenue programs which provide for recovery of costs and incentives or returns on investment in such items as transmission infrastructure, renewable energy resources or conservation initiatives.

The CompanyRestrictions

Otter Tail Corporation is a holding company with no significant operations of its own. The primary source of funds for payments of dividends to the Company’sour shareholders is from dividends paid or distributions made by the Company’sour subsidiaries. As a result of certain statutory limitations or regulatory or financing agreements, restrictions could occur on the amount of distributions allowed to be made by the Company’sour subsidiaries.

Both the CompanyOTC Credit Agreement and OTP credit agreementsCredit Agreement contain restrictions on the payment of cash dividends upon a default or event of default. An event of default, would be consideredincluding failure to have occurred if the Company did not meetmaintain certain financial covenants. As of June 30, 2020, the Company wasMarch 31, 2021, we were in compliance with these financial covenants.

Under the Federal Power Act, a public utility may not pay dividends from any funds properly included in a capital account. What constitutes “funds properly included in a capital account” is undefined in the Federal Power Act or the related regulations; however, the FERC has consistently interpreted the provision to allow dividends to be paid as long as (1)i) the source of the dividends is clearly disclosed, (2)ii) the dividend is not excessive and (3)iii) there is no self-dealing on the part of corporate officials.

The MPUC indirectly limits the amount of dividends OTP can pay to the Company by requiring an equity-to-total-capitalization ratio between 47.5% and 58.1% based on OTP’s 2020 capital structure petition effective by order of the MPUC on July 15, 2020. As of June 30, 2020, March 31, 2021, OTP’s equity-to-total-capitalization ratio including short-term debt was 52.9%52.4% and its net assets restricted from distribution totaled approximately $549$671.0 million. Under the 2020 capital structure petition, OTP’s total capitalization for OTP cannot exceed $1,704,607,000.

OTP has an all-requirements agreement with Navajo Transitional Energy Co. for the purchase of subbituminous coal for Hoot Lake Plant through December 31, 2023, with no fixed minimum purchase requirement.

OTP Land Easements

OTP has commitments to make future payments for land easements not classified as leases, extending into 2034 of approximately $9.9 million.

Contingencies

OTP had a $2.9 million refund liability on its balance sheet as of June 30, 2020. This represents its best estimateend of the refund obligations that would arise netperformance period ranges from 0 to 150% of amounts that would be subjectthe target amount based on two performance measures: i) total shareholder return relative to recovery under state jurisdictional TCR riders. Thisa peer group and ii) return on equity. The awards have no voting or dividend rights during the vesting period. Vesting of the awards is accelerated in certain circumstances, including on retirement. The amount of common shares awarded on an accelerated vesting is based either on actual performance at the outcomeend of the appeals of the FERC ruling reducing the ROE component of the MISO Tariff and ordering MISO to refund amounts charged in excess of the lower rate. As discussed in note 3 in greater detail, OTP believes its estimated accrued refund liability is appropriate based on the current facts and circumstances and is awaiting results of the appeal before determining if a change in this estimate will be needed.

Contingencies, by their nature, relate to uncertainties that require the Company’s management to exercise judgment both in assessing the likelihood a liability has been incurred as well as in estimatingperformance period or the amount of common shares earned at target.

Risk-free interest rate0.18 %1.42 %
Expected term (in years)3.003.00
Expected volatility32.00 %19.00 %
Dividend yield3.60 %2.80 %
The risk-free interest rate was derived from yields on U.S. government bonds of a similar term. The expected term of the award is equal to the three-year performance period. Expected volatility was estimated based on actual historical volatility of our common stock. Dividend yield was estimated based on historic and future yield estimates.

12. Earnings Per Share
The numerator used in the calculation of both basic and diluted earnings per common share is net income. The denominator used in the calculation of basic earnings per common share is the weighted average number of common shares outstanding during the period. The denominator used in the calculation of diluted earnings per common share is derived by adjusting basic shares outstanding for the dilutive effect of potential loss. common shares outstanding, which consist of time and performance based stock awards and employee stock purchase plan shares.
The following includes the computation of the denominator for basic and diluted weighted-average shares outstanding for the three months ended March 31, 2021 and 2020:

The level 2 fair value measurements for Government-Backed and Government-Sponsored Enterprises’ and Corporate Debt Securities are determined on the basis of valuations provided by a third-party pricing service which utilizes industry accepted valuation models and observable market inputs to determine valuation. Some valuations or model inputs used by the pricing service may be based on broker quotes.
In addition to the potential ROE refund described above, the most significant contingenciesassets recorded at fair value on a recurring basis, we also hold financial instruments that could impact the Company’s consolidated financial statements are those related to environmental remediation, risks associated with warranty claims relating to divested businesses that could exceed established reserve amounts, risks associated with adverse regulatory decisions that could impact the recovery of fixed asset costs in future rates and litigation matters.

On July 30, 2020 the MPUC ordered a reductionnot recorded at fair value in the remaining depreciable lives of OTP’s Hoot Lake Plant and seven hydroelectric plants. The MPUC stipulated recoverabilityconsolidated balance sheets but for which disclosure of the resulting increase in depreciation expense, which we estimate will be approximately $1.4 million on an annual basis, would be determined in OTP’s next rate case. Based onfair value of these financial instruments is provided. The following reflects the relevant factscarrying value and circumstances, OTP has concluded the additional depreciation expense is probableestimated fair value of recoverythese assets and will recognize a regulatory asset for the amount(liabilities) as of incremental expense recognized in 2020.

State implementation of pollution control plans to improve visibilityMarch 31, 2021 and air quality at national parks under the EPA’s Regional Haze Rule (RHR) could require OTP to incur significant new costs, which could, dependent on determinations by state regulatory commissions on approval to recover such costs from customers, negatively impact OTP’s and the Company’s net income, financial position and cash flows. The North Dakota Department of Environmental Quality (NDDEQ) must submit a state implementation plan to the EPA by July 2021. While this process is still in the early stages, if the NDDEQ and/or the EPA requires sources subject to RHR Round 2 reasonable progress determinations, including Coyote Station, to undertake emissions control measures that are reasonably consistent with those required of sources during Round 1, OTP anticipates that significant emissions controls would be required at Coyote Station by December 31, 2028. In light of the costs for emissions control equipment, there are scenarios where it may not be economically feasible to invest in such equipment and an early retirement of the Coyote Station would therefore be necessary. The costs related to an early retirement of Coyote Station would be material to OTP and the Company and would be subject to state commission approval for recovery from customers.

Other

The Company is a party to litigation and regulatory enforcement matters 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, 2020, other than those relating to the RHR, will not be material.

2019 Note Purchase Agreement

On September 12, 2019, OTP entered into a Note Purchase Agreement (the 2019 Note Purchase Agreement) with the purchasers named therein (the Purchasers), pursuant to which OTP agreed to issue to the Purchasers, in a private placement transaction, $175 million aggregate principal amount of OTP’s senior unsecured notes consisting of (a) $10,000,000 aggregate principal amount of its 3.07% Series 2019A Senior Unsecured Notes due October 10, 2029 (the Series 2019A Notes), (b) $26,000,000 aggregate principal amount of its 3.52% Series 2019B Senior Unsecured Notes due October 10, 2039 (the Series 2019B Notes), (c) $64,000,000 aggregate principal amount of its 3.82% Series 2019C Senior Unsecured Notes due October 10, 2049 (the Series 2019C Notes), (d) $10,000,000 aggregate principal amount of its 3.22% Series 2020A Senior Unsecured Notes due February 25, 2030 (the Series 2020A Notes), (e) $40,000,000 aggregate principal amount of its 3.22% Series 2020B Senior Unsecured Notes due August 20, 2030 (the Series 2020B Notes), (f) $10,000,000 aggregate principal amount of its 3.62% Series 2020C Senior Unsecured Notes due February 25, 2040 (the Series 2020C Notes) and (g) $15,000,000 aggregate principal amount of its 3.92% Series 2020D Senior Unsecured Notes due February 25, 2050 (the Series 2020D Notes; and together with the Series 2019A Notes, the Series 2019B Notes, the Series 2019C Notes, the Series 2020A Notes, the Series 2020B Notes and the Series 2020C Notes, the Notes).

On February 25, 2020, OTP issued the Series 2020A Notes, the Series 2020C Notes and the Series 2020D Notes pursuant to the 2019 Note Purchase Agreement. OTP used the $35 million proceeds from the issuance to pay for capital expenditures and for other corporate purposes. The Series 2019A Notes, Series 2019B Notes and Series 2019C Notes were issued by the Company on October 10, 2019. The remaining unissued notes of the Note Purchase Agreement, Series 2020B, are expected to be issued on August 20, 2020, subject to the satisfaction of certain customary conditions to closing.

OTP may prepay all or any part of the Notes (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 so prepaid, together with unpaid accrued interest and a make-whole amount; provided that if no default or event of default exists under the 2019 Note Purchase Agreement, any prepayment made by OTP of all of the (a) Series 2020A Notes then outstanding on or after August 25,2029, (b) Series 2020C Notes then outstanding on or after August 25, 2039 or (c) Series 2020D Notes then outstanding on or after August 25, 2049 will be made without any make-whole amount. The 2019 Note Purchase Agreement also requires OTP to offer to prepay all outstanding Notes at 100% of the principal amount together with unpaid accrued interest in the event of a Change of Control (as defined in the 2019 Note Purchase Agreement) of OTP.

The 2019 Note Purchase Agreement contains a number of restrictions on the business of OTP. These include restrictions on OTP’s abilities 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 2019 Note Purchase Agreement also contains other negative covenants and events of default, as well as certain financial covenants. Specifically, OTP may not permit its Interest-bearing Debt (as defined in the 2019 Note Purchase Agreement) to exceed 60% of Total Capitalization (as defined in the 2019 Note Purchase Agreement), determined as of the end of each fiscal quarter. OTP is also restricted from allowing its Priority Indebtedness (as defined in the Note Purchase Agreement) to exceed 20% of Total Capitalization, determined as of the end of each fiscal quarter. The 2019 Note Purchase 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 2019 Note Purchase Agreement includes a “most favored lender” provision generally requiring that in the event OTP’s existing credit agreement or any renewal, extension or replacement thereof, at any time contains any financial covenant or other provision providing for limitations on interest expense and such a covenant is not contained in the 2019 Note Purchase Agreement under substantially similar terms or would be more beneficial to the holders of the Notes than any analogous provision contained in the 2019 Note Purchase Agreement (an Additional Covenant), then unless waived by the Required Holders (as defined in the 2019 Note Purchase Agreement), the Additional Covenant will be deemed to be incorporated into the 2019 Note Purchase Agreement. The 2019 Note Purchase Agreement also provides for the amendment, modification or deletion of an Additional Covenant if such Additional Covenant is amended or modified under or deleted from the credit agreement, provided that no default or event of default has occurred and is continuing.

12. 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 EquivalentsEquivalents: The carrying amount approximates fair value because of the short-term maturity of those instruments.

Short-Term DebtDebt: The carrying amount approximates fair value because the debt obligations are short-term and the balances outstanding as of June 30, 2020 and December 31, 2019 related to the Otter Tail Corporation Credit Agreement wereare subject to variable interest rates of LIBOR plus 1.50%,interest which approximate market rates.

reset frequently, a Level 2 fair value input.

Long-Term Debt including Current MaturitiesDebt: The fair value of the Company's and OTP’s long-term debt is estimated based on the current market indications for borrowings of rates available tosimilar maturities, a Level 2 fair value input.

Otter Tail Corporation (the Company, we, usmetal components and our) continuesmanufactures extruded and thermoformed plastic products. Our Plastics segment manufactures PVC pipe for use in, among other applications, municipal and rural water, wastewater, and water reclamation projects.

COVID-19
We continue to monitor the progression of the novel coronavirus (COVID-19) and its impact on our businesses, employees, customers, construction contractors and vendors. As this pandemic continues, we are following the directives and advice of government leaders and medical professionals and have adopted practices to help curtail the spread of the virus and mitigate its impact on our communities, employees, construction contractors, customers and business operations. Our Electric segment business provides a critical service to our customers and our manufacturing platform businesses provide products and support to critical infrastructure industries. All of our operating companies have been deemed critical infrastructure businesses. Accordingly, weWe continue to operate our businesses in a manner that is safe for our employees and our customers.

We began to see a reductionoperating results were also impacted in customer demand in our Manufacturing segment in late March 2020 and have experienced significantly lower levels of customer demand in this segment through the end of June 2020. We anticipate this reduced demand will continue over the near term. Within our Electric segment, we have experienced reduced demand from commercial and industrial customers and the risk of disruptions for our capital projects, including Merricourt and Astoria Station, also continues. With over 250 individuals working on the Astoria Station site at times during various stages of construction, 26 have tested positive for COVID-19. Continued or additional incidence of infection at the Astoria Station or Merricourt sites, may result in delayed completion schedules and increased costs for these projects.bad debts.

Financial And OTHER metrics USED IN THE FOLLOWING DISCUSSION

Heating Degree Days (HDDs) is a measure of how much (in degrees), and for how long (in days), the outside air temperature was below a certain level. This measure is commonly used in calculations relatingbusiness. However, due to the energy consumption required to heat buildings.

Cooling Degree Days (CDDs) is a measureunprecedented and evolving nature of how much (in degrees), and for how long (in days),this pandemic, we cannot predict the outside air temperature was above a certain level. This measure is commonly used in calculations relating to the energy consumption required to cool buildings.

Otter Tail Power Company (OTP) generally bases its forecasted kilowatt-hour (kwh) sales and rates on expected consumption under a normal level of HDDs and CDDs over a given period of time in its service territory. Increased or decreased levels of consumption for certain customer classifications are attributed to deviation from the norms and are a significant factor influencing consumption of electricity across our service territory. We present HDDs and CDDs to provide an indicationfull extent of the impact of weatherCOVID-19 will have on kwh sales, revenues and earnings relative to forecast and on period-to-period results.

Backlog, expressed in dollars, is the level of sales orders received but not yet completed by a company or operating segment. The Company discloses these figures for its Manufacturing segment as an indication of future business volume within the segment.

Utility Rate Base is the value of property on which a public utility is permitted to earn a specified rate of return in accordance with rules set by a regulatory agency. In general, the rate base consists of the value of property used by the utility in providing service. Rate base can include: cash, working capital, materials and supplies, deductions for accumulated provisions for depreciation, contributions in aid of construction, customer advances for construction, accumulated deferred income taxes, and accumulated deferred investment tax credits, dependent on the method that is used in the calculation, which can vary from jurisdiction to jurisdiction. The Company presents actual and forecasted levels of utility rate base in its outlook to provide an indication of expected investments on which the Company expects to earn future returns.

Table of Contents
Operating Expenses increased $22.1 million primarily due to increased costs of products sold in our Plastics and Manufacturing segments due to increased raw material costs in each segment. Operating expenses in our Electric segment increased primarily due to higher depreciation and amortization expense arising from our recent rate base investments. See our segment disclosures below for additional discussion of items impacting operating expenses.
Interest Charges increased $1.3 million mostly due to:
A $0.5 million increase in interest expense related to OTP long-term debt issuances of $35 million in February 2020 and $40 million in August 2020.
A $0.3 million reduction in capitalized interest at OTP related to the completion and start up of Astoria Station in the first quarter of 2021.
A $0.4 million increase in corporate interest expense due to a higher level of short-term borrowings between the quarters as well as an increase in the cost of borrowing.
Nonservice Cost Components of Postretirement Benefits decreased $0.5 million due to a change in how prescription drug coverage is provided to retirees and due to the impact on nonservice costs of a 70 basis point drop in the discount rate from 2020 to 2021.
Other Income increased $1.5 million primarily due to increases in the cash values of corporate-owned life insurance policies and captive insurance company investments in the first quarter of 2021 compared with $229.2to losses in value in the first quarter of 2020.
Income Tax Expense decreased $0.4 million despite a $5.7 million increase in income before income taxes primarily due to PTCs earned in the first quarter of 2021 from our Merricourt wind farm, which was placed in service in the fourth quarter of 2020. Our effective tax rate was 14.8% in the first quarter of 2021 and 18.9% in the first quarter of 2020.

Table of Contents
A $2.8 million decrease in retail revenue mainly due to decreased kwh sales to commercial and industrial customers, exclusive of the impact of milder weather on sales, due to ongoing impacts of COVID-19 on first quarter 2021 kwh sales. COVID-19 did not impact electric revenues in the first quarter of 2020.
A $1.5 million decrease in fuel recovery revenue includes:

A $4.2 million decrease in retail revenue related to the recovery of decreased fuel and purchased power costs incurred to serve retail customers. Decreased commercial and industrial demand related to COVID-19 contributed to the 5.1% decrease in retail kwh sales and a $5.2 million decrease in fuel and purchased power costs to serve retail customers.

A $2.7 million decrease in revenue due to decreased kwh sales to commercial and industrial customers, exclusive of the decrease in fuel cost recovery revenues, mainly due to COVID-19-related impacts in the second quarter of 2020.

A $1.0 million combined decrease in South Dakota Phase-In Rider revenues and Minnesota Conservation Improvement Program Rider revenues.

mainly due to credits provided to customers from increased margins on wholesale kwh sales and a 5.7% reduction in retail kwh sales between the quarters.

A $0.9 million decrease in retail revenues related to decreased consumption due to milder weather in the first quarter of 2021 compared with the first quarter of 2020, evidenced by a 5.9% decrease in heating-degree days between the quarters.
These decreases in revenue were partially offset by:

A $2.9 million increase in Minnesota and North Dakota renewable rider revenues related to earning a return on funds invested in the Merricourt Wind Energy Center (Merricourt) while the project is under construction.

A $1.3 million increase in revenues related to increased consumption due to favorable quarter over quarter weather impacts.

A $0.7 million increase in revenues from the North Dakota Generation Rider which went into effect in July 2019 to provide a return on funds invested in Astoria Station while the generation project is under construction.

A $0.2 million increase in revenue related to volume sales increases of electricity to residential customers exclusive of the impact of weather on sales.

Transmission services revenue decreased $1.8

A $2.3 million mainly dueincrease in new retail revenues, net of an estimated refund, related to lower tariffs and decreased transmission volume resulting from lower electrical demand partially attributable to the impact of COVID-19.

Thean interim rate increase in Minnesota effective January 1, 2021 in connection with OTP's current Minnesota rate case filed in November 2020.

A $0.7 million increase in other revenue includes $1.0conservation rider revenues related to the recovery of increased conservation improvement program spending in Minnesota and South Dakota.
A $0.5 million from a commercial customerincrease in renewable rider revenues in North Dakota related to recovery of Merricourt operating expenses and returns on increased investment in the secondproject, which was placed in service in the fourth quarter of 2020.
A $0.5 million increase in retail revenue due to a positive price variance resulting from varying kwh sales to customers under different tariffs.
A $0.3 million net increase in North Dakota and South Dakota generation, transmission and phase-in rider revenues related to the recovery of Astoria Station and transmission project costs.
Transmission Services Revenues increased $1.1 million due to increases of $0.7 million in generator interconnection revenues under two new agreements which began billing after the first quarter of 2020 partially offsetand $0.4 million in Midcontinent Independent System Operator. Inc. (MISO) transmission services tariff revenues.
Wholesale Electric Revenue increased $3.6 million as a result of a 106.6% increase in wholesale kwh sales and a 149% increase in wholesale electric prices driven by a $0.3 million decrease in revenue from steam sales to an ethanol producer due to Big Stone Plant being on economic dispatchhigh market demand and not producing steam at certain timesavailability constraints during the second quarterFebruary 2021 cold weather, which drove up spot market prices for electricity.
Production Fuel costsincreased $1.0 million mainly as a result of 2020.

Production fuel costs increased $0.5 million despite an 11.7% decreasea 16.2% increase in kwhs generated from our fuel-burning plants mainly as a result of a 20.0% increasedue to higher demand and favorable prices for energy in fuel-cost per kwh of generation, weighted heavily by higher fuelwholesale markets. Fuel costs per kwh of generation decreased 7.8% at Coyote Stationour fuel-burning plants as a result of increased efficiencies at higher and longer-sustained levels of generation. Fuel costs per kwh of generation including renewable generation decreased 15.4% as a result of Merricourt being added to our generation mix in the second quarter ofDecember 2020. Coyote Station was down for maintenance in the second quarter of 2019.

The cost of purchased power

Purchased Power costs to serve retail customers decreased $6.0increased $0.4 million as a result of a 26.2% decrease in purchased power prices, driven mainly by low prices for natural gas-fired generation, and a 5.6% decrease in kwhs purchased. The decrease in purchased power volume is due, in part, to COVID-19-related declines in electricity use by commercial and industrial customers.

Electric operating and maintenance expense decreased $6.7 million, including:

A $3.0 million decrease in contracted services and materials and supplies expenses at Coyote Station related to the plant's second quarter 2019 extended maintenance outage.

A $1.1 million decrease in labor and benefit expenses.

A $1.0 million decrease in transmission tariff expenses related to decreased kwh purchases and decreased transmission tariff rates.

A $0.9 million decrease in vegetation maintenance expenses and conservation improvement program expenditures.

A $0.6 million decrease in materials and supplies and contracted services expenses at Hoot Lake Plant related to second quarter 2019 turbine repairs.

A $0.4 million decrease in travel-related expenses related to COVID-19 travel restrictions was offset by a $0.4 million26.6% increase in customer bad debt expense provisions due to adoption of COVID-19-related service suspension and debt collection policies.

Depreciation expense increased $0.7 million mainly due to 2019 capital additions for generation and transmission plant.

The $27.5 million decrease in revenues in our Manufacturing segment includes the following:

Revenues at BTD Manufacturing, Inc. (BTD) decreased $26.0 million. Parts revenue was down $19.8 million related to decreased sales volumes to all end market customer categories served by BTD, in order of magnitude: recreational vehicle, construction, lawn and garden, agricultural, industrial and energy equipment end markets, as customers implemented temporary plant shutdowns due to the COVID-19 pandemic. Lower prices related to the pass through of lower material costs accounted for a $5.9 million decrease in parts revenue, partially offset by $0.5 million in price increases exclusive of the pass through of material cost reductions. Scrap revenue decreased $0.8 million due to a 46.8% decrease in scrap volume and a 5.1% decrease in scrap metal prices.

Revenues at T.O. Plastics, Inc. (T.O. Plastics), our manufacturer of thermoformed plastic and horticultural products, decreased $1.5 million primarily due to decreases of $0.9 million in sales of horticultural containers, $0.3 million in industrial sales and $0.2 million in life sciences product sales. The decreased sales level was mainly due to market softness generated by the uncertainty of how COVID-19 was going to impact these end markets.

The $20.3 million decrease in cost of products sold in our Manufacturing segment includes the following:

Cost of products sold at BTD decreased $19.5 million as a result of both the decreased sales volume and the $5.9 million in lower material costs passed through to customers.

Cost of products sold at T.O. Plastics decreased $0.8 million related to the decrease in sales volume.

The $2.5 million decrease in operating expenses in our Manufacturing segment includes a $2.3 million decrease in operating expenses at BTD related to initiatives taken at BTD to mitigate the negative impacts on sales related to COVID-19, mainly reductions in salaries, incentives and benefits, travel and outside services expenditures. Operating expenses at T.O. Plastics decreased $0.2 million, mainly due to decreases in salaries and incentives.

BTD incurred $1.0 million in termination costs in the second quarter of 2020, with $0.9 million charged to cost of products sold and $0.1 million charged to operating expense, related to headcount reductions across all its sites in response to the ongoing reduction in sales volume.

We estimate COVID-19 issues at BTD negatively impacted our second quarter earnings by approximately $0.08 per share. This relates to reduced sales, as customers initiated or continued temporary plant shutdowns which caused lost labor productivity, and costs related to personal protective equipment. BTD also continued to pay health care costs for furloughed employees.

Plastics segment revenues and operating income decreased $4.8 million and $0.9 million, respectively, due to a 5.8% decrease in pounds of polyvinyl chloride (PVC) pipe sold in combination with a 3.3% decrease in PVC pipe prices. The decrease in

sales volume is attributed to a drop in sales to distributors who reduced inventory levels due to uncertainty over the impact of COVID-19 on sales and expectations of PVC pipe prices decreasing in light of declining resin prices in the second quarter of 2020. Cost of products sold decreased $3.9 million due to the decrease in sales volume and a 3.7% decrease in the cost per pound of PVC pipe sold mainly due to a decrease in resin costs. The decrease in pipe prices partially offset by a decrease in resin prices resulted in a 2.0% decrease in gross margin per pound of PVC pipe sold.

Interest Charges

Interest charges increased to $8.7 million in the three months ended June 30, 2020 from $7.8 million in the three months ended June 30, 2019. The $0.9 million increase in interest charges is primarily due to an increase in interest expense at OTP related to debt issuances of $100 million in October of 2019 and $35 million in February of 2020 under OTP’s 2019 Note Purchase Agreement.

Other Income

Other income increased to $2.4 million in the three months ended June 30, 2020 from $0.8 million in the three months ended June 30, 2019. The $1.6 million increase in other income includes:

A $0.7 million increase in allowance for equity funds used during construction at OTP mostly related to the Minnesota share of construction work in progress on OTP’s Astoria Station project.

A $0.6 million increase in the cash surrender value of corporate-owned life insurance policies held by the Company.

A $0.2 million increase in unrealized gains earned on equity investments held by our captive insurance company, Otter Tail Assurance Limited.

Income Tax Expense

Income tax expense increased $0.5 million in the three months ended June 30, 2020 compared with the three months ended June 30, 2019 mainly due to the tax effect of a $2.0 million increase in income before income taxes.

Effect on Diluted Earnings Per Share

 $0.01  $0.08  $(0.07)

The $10.1 million decrease in retail sales revenue includes:

A $12.0 million decrease in retail revenue related to the recovery of decreased fuel and purchased power costs to serve retail customers. Decreased demand caused by the milder winter weather and the impacts of COVID-19 contributed to a 20.1% decrease in kwhs generated for system use and a $4.1 million decrease in fuel costs. Purchased power costs decreased by $9.1 million despite a 5.1% increase in kwhs purchased due to a 25.6% decrease in purchased power prices.

A $3.9 million decrease in revenues related to decreased consumption due to milder weather in the first six months of 2020 compared with the first six months of 2019, evidenced by a 16.0% decrease in heating-degree days between the periods.

A $1.0 million decrease in retail revenue in South Dakota related to the first quarter 2019 reversal of a tax refund provision accrued in 2018 in connection with OTP's 2018 South Dakota rate case settlement agreement.

A $0.4 million decrease in revenue due to decreased kwh sales to commercial and industrial customers resulting from a $2.2 million reduction in commercial and industrial sales due to COVID-19-related impacts on sales in the second quarter of 2020, mostly offset by increased sales resulting from a large commercial customer expanding its production capacity and increasing demand.

A $0.2 million decrease in transmission rider revenues.

These decreases in revenue were partially offset by:

A $5.3 million increase in Minnesota and North Dakota renewable rider revenues related to earning a return on funds invested in Merricourt while the project is under construction.

$1.4 million in revenues from the North Dakota Generation Rider which went into effect in July 2019 to provide a return on funds invested in Astoria Station while the generation project is under construction.

A $0.6 million increase in revenue related to volume sales increases of electricity to residential and commercial customers exclusive of the impact of weather on sales.

Transmission services revenue decreased $1.8 million mainly due to a reduction in transmission tariff revenues related to decreased transmission volume resulting from lower electrical demand partially attributable to the impact of COVID-19.

Wholesale electric revenues decreased $0.8 million due to lower wholesale electric prices and a 1.3% decrease in wholesale kwh sales. The lower wholesale prices per kwh resulted in a $0.2 million decrease in margins on wholesale energy sales from OTP’s generating units in the first six months of 2020 compared with the first six months of 2019.

Production fuel costs decreased $4.7 million due to a 23.2% decrease in kwhs generated at OTP’s fuel-burning generation plants, partially offset by a 7.8% increase in fuel costs per kwh generated. A 69.7% increase in generation at Coyote Station, which was offline for maintenance during the entire second quarter of 2019, was more than offset by decreases in generation at both Big Stone Plant and Hoot Lake Plant, which were curtailed due to economic dispatch as reduced demand and lower prices for alternative fuels and generation sources drove market prices for electricity down in the second quarter of 2020.

The cost of purchased power to serve retail customers decreased $9.1 million as a result of a 25.6% decrease in purchased power prices, partially offset by a 5.1% increase19.2% decrease in kwhs purchased. The decreaseincrease in marketkwh prices for electricitymainly was driven by low priceshigh market demand for natural gas-fired generationelectricity and availability constraints caused by the February 2021 cold weather.

Operating and MaintenanceExpense increased $0.8 million mainly due to:
$1.2 million in combination with lower demand in the second quarter of 2020 due to COVID-19-related declines in electricity use by commercial and industrial consumers.

ElectricMerricourt operating and maintenance expense decreased $4.4 million, including:

A $3.4 million decrease in contracted services and materials and supplies expenses at Coyote Station, mainly related to the plant's secondexpenses incurred in the first quarter 2019 extended maintenance outage.

A $1.5 million decrease in transmission tariff expenses related to decreased rates.

A $0.5 million decrease in materials and supplies and contracted services expenses at Hoot Lake Plant related to second quarter 2019 turbine repairs.

A $0.5 million decrease in pollution control reagent costs due to a 23.9% decrease in kwhs generated at OTP’s coal burning plants between periods.

These items were partially offset by:

A $1.6 million net increase in labor and benefit costs.

A $0.7 million decrease in travel and employee education expenses related to COVID-19 travel restrictions and social distancing requirements was offset by a $0.7 million increase in customerconservation improvement program expenditures, which are being recovered through retail rate riders in Minnesota and South Dakota.
These increases in expense were partially offset by:
A $0.6 million decrease in steam generation plant maintenance and operating expenses.
A $0.5 million decrease in bad debt expense provisions due to adoption of COVID-19-related service suspension and debt collection policies.

Depreciation expense increased $1.8 million mainly due to 2019 capital additions for generation and transmission plant, the newimproved customer information system that went into service duringcollections in the first quarter of 20192021.

Operating Income$7,545 $6,841 $704 10.3 %
Operating Revenues increased $7.3 million primarily due to the following:

Revenues at BTD decreased $36.2 million. Parts revenue was down $22.5 million related to decreased sales volumes to all end market customer categories served by BTD, in order of magnitude: recreational vehicle, construction, lawn and garden, agricultural, energy equipment and industrial end markets, as customers implemented temporary plant shutdowns due to the COVID-19 pandemic. Lower prices related to the pass through of lower material costs accounted for a $13.0 million decrease in parts revenue, partially offset by $0.6 million in price increases exclusive of the pass through of material cost reductions. In addition to the decrease in parts revenue, scrap revenue decreased $1.4 million due to a 30.1% decrease in scrap volume and a 13.0% decrease in scrap metal prices.

Revenues at T.O. Plastics decreased $0.7 million primarily due to a $0.6 million decrease in industrial sales and a $0.3 million decrease in sales of life sciences products and scrap material, partially offset by a $0.2 million increase in sales of horticultural containers. The $0.9 million in decreased sales of industrial and life sciences products is associated with lower demand from customers due to COVID-19-related impacts on customer’s production and sales activity.

At BTD, revenues increased $6.2 million, consisting of $4.4 million in material cost increases passed through to customers and $1.8 million in volume and price increases. The $28.9volume increase was driven by stronger sales in the recreational vehicle, agricultural, lawn and garden and construction end markets offset, in part, by a decline in sales primarily in the energy end market. Scrap revenues increased $1.5 million decreasemostly due to increases in costscrap metal prices, but also due to increases in scrap volumes from increased sales and production activity. These increases in revenue were, partially offset by lower tooling and other revenues.
At T.O. Plastics, revenues increased $0.4 million. A $1.0 million increase in horticultural product sales was partially offset by decreases in industrial, life sciences and other product sales totaling $0.6 million.
Cost of Products Sold increased $5.7 million due to the following:
Cost of products sold at BTD increased $5.9 million as a result of higher material prices and sales-volume-driven increases in our Manufacturing segment includesmaterial and labor costs.
Cost of products sold at T.O. Plastics decreased $0.2 million due to lower material costs resulting from a higher mix of product sales utilizing reclaimed material and the following:

Cost of products sold at BTD decreased $29.1 million as a result of both the decreased sales volume and the $13.0 million in lower material costs passed through to customers.

Cost of products sold at T.O. Plastics increased $0.2 million due to an increases in rental costs for more warehouse space and increases in other indirect costs, despite a $0.5 million decrease in material costs related to the decrease in sales volume.

The $3.3 million decreasereduction in operating expensesindustrial and life sciences product sales, which more than offset increases in our Manufacturing segment includes a $2.5 million decrease in operatingmaterial costs on increased horticultural product sales.

Other Operating Expenses increased $0.9 million. Operating expenses at BTD relatedincreased $0.5 million mainly due to initiatives taken at BTD to mitigate the negative impacts on sales related to COVID-19, mainly reductionsincreases in salaries, incentives and benefits, travel and outside services expenditures.operating expenses. Operating expenses at T.O. Plastics decreased $0.8increased $0.4 million, including $0.4mainly due to recognition of an expense reduction of $0.6 million related to insurance settlement proceeds received in the first quarter of 2020.

Operating Income$12,586 $7,467 $5,119 68.6 %
Operating Revenues increased $15.8 million due to a 34% increase in the price per pound of PVC pipe sold and a 1.1% increase in pounds of PVC pipe sold. The price increase was driven, in part, by PVC resin supply constraints due to resin production plant shutdowns and feedstock shortages related to abnormally low temperatures and snowstorms in the Gulf Coast region of the United States in February 2021 and significant global demand for PVC resin and limited pipe inventory across the country. Cost of products sold increased $10.4 million primarily due to increased PVC resin and other material cost increases.
Cost of Products Sold increased $10.4 million primarily due to increased PVC resin and other material cost increases.
Other Operating Expenses increased $0.2 million as a result of the receipt of insurance settlement proceeds in the first quarter of 2020 and a $0.3 million write off of the value of destroyed property in 2019increased incentive benefits directly related to the March 2019 partial roof collapse. T.O, Plastics travel and other selling expenses decreased by $0.1 million due to restrictions on activity in response to COVID-19-related safety initiatives.

BTD incurred $1.0 million in termination costs in the second quarter of 2020, with $0.9 million charged to cost of products sold and $0.1 million charged to operating expense, related to headcount reductions across all its sites in response to the ongoing reduction in sales volume.

We estimate COVID-19 issues at BTD negatively impacted our earnings by approximately $0.09 per share in the first six months of 2020. This relates to reduced sales as customers initiated or continued temporary plant shutdowns which caused lost labor productivity, and costs related to personal protective equipment. BTD also continued to pay health care costs for furloughed employees.

CORPORATE COSTS
The sales volume increase resulted mainly from weather conditions that negatively impacted sales across our sales territory in the first quarter of 2019. Cost of products sold remained unchanged despite the increase in sales volume due to a 4.2% decrease in the cost per pound of pipe sold, mainly due to decreased resin costs. These items resulted in a 2.9% increase in gross margin per pound of PVC pipe sold.

REGULATORY RATE MATTERS
The following provides a summary of general rate case filings and rate rider filings that have or are expected to have a material impact on our operating results, financial position or cash flows.
GENERAL RATES
Minnesota Rate Case: On November 2, 2020, OTP filed a request with the MPUC for an increase in revenue recoverable under general rates in Minnesota. In its filing, OTP requested a net decrease in incentive and benefit costs of $0.5 million and a $0.3 million decrease in contracted service expenditures.

Interest Charges

Interest charges increased to $16.8 million in the six months ended June 30, 2020 from $15.7 million in the six months ended June 30, 2019. The $1.1 million increase in interest charges isannual revenue of approximately $14.5 million, or 6.77%, based on an allowed rate of return on rate base of 7.59% and an allowed rate of return on equity of 10.20% on an equity ratio of 52.5% of total capital. Through this proceeding, OTP has proposed changes to the mechanism of cost recovery, with some costs moving from riders into base rates and fuel, purchased power, and conservation program costs moving out of base rates and into riders. The filing also included a revenue decoupling mechanism proposal. Such mechanisms are designed to separate a utility's revenue from changes in energy sales. The decoupling mechanism uses a tracker balance in which authorized customer margins are subject to a true-up mechanism to maintain or cap a given level of revenues.

On December 3, 2020, the MPUC approved an interim annual rate increase of $6.9 million, or 3.2%, effective January 1, 2021. This approval was provided after an alternative recovery proposal was submitted by OTP, which, among other changes, requested the extension of depreciable lives of certain wind-related assets and deferred certain cost recovery decisions to the final rate determination. In the aggregate, this alternative recovery proposal reduced operating costs and delayed recovery of certain other costs by approximately $7.0 million to lessen the interim rate impact on customers.
In a filing submitted to the MPUC on April 30, 2021, OTP lowered its requested net annual revenue increase from its initial request of $14.5 million to $8.2 million, primarily due to an increasea reduction in interestoperating costs from amounts included in its November 2020 filing. The cost reductions include, among other items, lower depreciation expense at OTP relatedon our wind generation assets due to debt issuancesthe extension of $100 milliondepreciable lives from 25 to 35 years and a reduction in October of 2019 and $35 million in February of 2020 under OTP’s 2019 Note Purchase Agreement.

Minnesota TCR. On May 1, 2017, the MPUC ordered OTP to include in the TCR rider retail rate base the Minnesota jurisdictional share of OTP's investments in certain transmission assets and all revenues received from other utilities under MISO's tariffed rates as a credit in its TCR revenue requirement calculations. The order had the effect of diverting interstate wholesale revenues that have been approved by the FERC to offset the FERC-approved expenses, effectively reducing OTP's recovery of FERC-approved expense calculatedlevels.
On August 18, 2017, OTP filed an appeal of the MPUC order with the Minnesota Court of Appeals to contest the portion of the order requiring OTP to jurisdictionally allocate costs of the FERC transmission projects in the TCR rider. On June 11, 2018, the Minnesota Court of Appeals reversed the MPUC's order. On July 11, 2018 the MPUC filed a petition for review of the decision to the Minnesota Supreme Court, which granted review of the appellate court decision. The Minnesota Supreme Court issued its opinion on April 22, 2020, concluding the MPUC lacked authority to amend an existing TCR rider approved under Minnesota state law to include the costs and revenues associated with these transmission projects and affirming the decision of the Minnesota Court of Appeals.
On October 22, 2020, the MPUC approved OTP's request for a Minnesota TCR rider update with the exclusion of these transmission projects. In addition, the MPUC approved the inclusion of three new projects previously requested in the Minnesota TCR rider eligibility petition. Updated rates went into effect in January 2021. With this decision, one-half of the projected TCR rider tracker balance at our net composite federal and state statutory rate on income before income taxes on our consolidated statementsDecember 2020 of income.

LIQUIDITY
LIQUIDITY OVERVIEW
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 us ample liquidity to conduct business operations and fund our capital expenditures related to expansion of existing businesses and development of new projects.expenditure plans. Our liquidity, including our operating cash flows and access to capital markets, can be impacted by macroeconomic factors outside of our control, such as those which may be caused by COVID-19. In addition, our liquidity could be impacted by non-compliance with covenants under our various debt instruments. As of June 30, 2020,March 31, 2021, we were in compliance with all debt covenants (see the Financial CovenantCovenants section under Capital Resources below).

As of June 30, 2020, COVID-19 and the resulting deteriorating economic conditions had not had a material impact on our liquidity.

We continue to have sufficient liquidity under our credit facilities to support our operating companiesbusiness based on the current economic environment. We are closely monitoring our liquidity and capital market conditions given the uncertainty surrounding the impact of COVID-19, which could have an adverse effect on the availability and terms of future debt and equity financing.

Net Cash Provided by Operating Activities$15,270 $21,777 
Net Cash Provided by Operating Activities decreased $6.5 million for the three months ended March 31, 2021 compared to the three months ended March 31, 2020. An increase in net income in 2021 was more than offset by an increase in working capital requirements, which was primarily the result of increased accounts receivables within our Manufacturing and Plastics segments due to strong sales volumes and increased sales prices during the three months ended March 31, 2021. We expectmade a discretionary contribution to issue our Series 2020B Notespension plan of $10.0 million during the three months ended March 31, 2021 compared to a contribution of $11.2 million in 2020. We do not anticipate making any further discretionary contributions to the pension plan in 2021.

Net Cash Used in Investing Activities decreased $26.0 million for the three months ended March 31, 2021 compared to the three months ended March 31, 2020. The decrease is primarily the result of lower capital investment within our Electric segment as capital spending on August 20,our large generation assets, Merricourt and Astoria Station, were largely completed in the fourth quarter of 2020.

Net Cash Provided by Financing Activities$33,799 $39,967 
Net Cash Provided by Financing Activities decreased $6.2 million for the three months ended March 31, 2021 compared to the three months ended March 31, 2020, to provide an additional $40.0primarily as a result of a decrease in financing needs given the lower level of capital spending in our Electric segment in 2021. Financing activities in the three months ended March 31, 2021 included a net borrowing increase of $53.9 million under our line of liquidity.

CAPITAL REQUIREMENTS
CAPITAL EXPENDITURES
We have a capital expenditure program for expanding, upgrading and improving our plants and operating equipment. Typical uses of cash for capital expenditures are investments in electric generation facilities and environmental upgrades, transmission and distribution lines, manufacturing facilities and upgrades, equipment used in the manufacturing process, and computer hardware and information systems. Our capital expenditure program is subject to review and is revised in light of changes in demands for energy, technology, environmental laws, regulatory changes, business expansion opportunities, the costs of labor, materials and equipment and our financial condition. Refer to Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations, of our Form 10-K for the year ended December 31, 2020 for our capital expenditure plan for the five year period from 2021 through 2025.
CONTRACTUAL OBLIGATIONS
Our contractual obligations primarily include principal and interest payments due under our At-the-Market offering program, Dividend Reinvestmentoutstanding debt obligations, commitments to acquire coal, energy and Employee Stock Purchase planscapacity commitments, payments to meet our postretirement benefit obligations, and payment obligations under land easement and leasing arrangements. Our contractual obligations as of December 31, 2020 are included in Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations, of our Form 10-K for the year ended December 31, 2020. There were no material in our contractual obligations outside of the ordinary course of our business during the three months ended March 31, 2021.
COMMON STOCK DIVIDENDS
We paid dividends to our common stockholders totaling $16.2 million, or $0.39 per share, in the first sixthree months of 2020. We expect to issue up to an additional $28 million in common equity under these programs barring any further deteriorations of the capital markets from the COVID-19 pandemic or other factors. If weakened economic conditions persist for a prolonged period of time, we are prepared to add additional liquidity as necessary, including exercising the accordion features under our lines of credit to increase our available borrowing capacity under the lines by a combined $200 million.

Equity and debt financing will be required in the period 2020 through 2024 given the expansion plans related to our Electric segment to fund construction of new rate base investments. Also, such financing will be required should we decide to reduce borrowings under our lines of credit or refund or retire early any of our presently outstanding debt, to complete acquisitions or for other corporate purposes. The terms and conditions and the timing of our equity and debt financing activities could be impacted by the economic effects of COVID-19 and the resulting market volatility. 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.

2021. 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, cash flows from operations, the level of our capital expenditures and our future business prospects. As a result of certain statutory limitations or regulatory or financing agreements, restrictions could occur on the amount of distributions allowed to be made by our subsidiaries. See note 7Note 10 to our consolidated financial statements included in this report on Form 10-Q for additional information. The decision to declare a dividend is reviewed quarterly by the boardour Board of directors. On February 4, 2020 our board of directors increased the quarterly dividend from $0.35 to $0.37 per common share.

The primary reasons for the $4.6 million increase in cash provided by operations between the quarters were a $2.3 million increasestrong financial coverages and investment grade credit ratings. Equity or debt financing will be required in the non-cash depreciation expense and a $2.1 million decrease in cash used for workingperiod 2021 through 2025 to support our capital items between the quarters.

Net cash used in investing activities was $121.0 million for the six months ended June 30, 2020 compared with $55.4 million for the six months ended June 30, 2019. The $65.6 million increase is mainly dueinvestments, primarily within our Electric segment to a $70.3 million increase in cash used for construction expenditures at OTP, partially offset by a $4.5 million net decrease in capital expenditures in our nonutility businesses. OTP’s cash used for capital expenditures totaled $113.9 million in the first six months of 2020 compared with $43.6 million in the first six months of 2019. The majority of the 2020 expenditures at OTP related to thefund construction of Astoria Stationnew rate base and Merricourt.

As of June 30, 2020, OTP had capitalized approximately $131.7 million in project costs and allowances for funds used during construction (AFUDC) associated with Merricourt. OTP estimates its direct generation and transmission capital costs for the Merricourt project will be approximately $260 million. Additional transmission system upgrades for the project amounting to approximately $6.5 million will be made by a neighboring MISO transmission owner. OTP has received Notices of Force Majeure from EDF-RE US Development, LLC claiming rights to an extension of guaranteed project completion dates and adjustments to the consideration agreed upon in the TEPC Agreement due to COVID-19 impacts. While details regarding these claims and impact to the project remain uncertain, OTP currently expects Merricourt to be completed before December 31, 2020. These and other potential impacts of COVID-19-related disruptions continue to present risks for the schedule, costs and timing of payments related to the project.

As of June 30, 2020, OTP had capitalized approximately $108.0 million in project costs and AFUDC associated with Astoria Station. OTP estimates its direct generation and transmission capital costs for the Astoria Station project will be approximately $154 million and anticipates the plant will be online in late 2020 or early 2021, prior to the planned retirement of Hoot Lake Plant in May 2021. OTP has not altered the construction schedule for Astoria Station due to COVID-19. However, COVID-19-related disruptions have increased risks for the project workforce given, among other factors, that it involves more than 250 construction workers on site and 26 have tested positive for COVID-19. Circumstances continue to evolve which could result in a delay in completion and increased costs for the project.

As of June 30, 2020, our capital expenditure activities had not been materially impacted by COVID-19. However, future supply chain, workforce, contractor or other disruptions could result in added costs and lead to delayed completion of certain of our capital expenditure projects. We are actively monitoring our supply chains and working with our contractors to ensure the continued safety of all parties.

Contractual Obligations

In the first six months of 2020, OTP paid down a portion of its $317 million in obligations for commitments under contracts in place as of December 31, 2019, reducing its obligations for commitments under contracts to $185 million as of June 30, 2020. This includes commitments related to the construction of Astoria Station and Merricourt of $163 million for the remainder of 2020 and $6 million for 2021. In the first quarter of 2020, OTP increased its debt obligations by $35 million in the years beyond 2024.

As of June 30, 2020, OTP’s Interest and Dividend Coverage Ratio and Interest Charges Coverage Ratio, calculated under the requirements of the 2007 Note Purchase Agreement and 2011 Note Purchase Agreement, was 3.70 to 1.00.

Under the 2013 Note Purchase Agreement, the 2018 Note Purchase Agreement, and the 2019 Note Purchase Agreement, OTP may not permit its Interest-bearing Debt to exceed 60% of Total Capitalization and may not permit its Priority Indebtedness to exceed 20% of its Total Capitalization, in each case as provided in the related agreement.

As of June 30, 2020, our ratio of Interest-bearing Debt to Total Capitalization was 0.48 to 1.00 on a consolidated basis and 0.47 to 1.00 for OTP. Neither Otter Tail Corporation nor OTP had any Priority Indebtedness outstanding as of June 30, 2020.

OFF-BALANCE-SHEET ARRANGEMENTS

We and our subsidiary companiesMarch 31, 2021 we have outstanding letters of credit totaling $12.1$16.4 million, buta portion of which reduces our lineborrowing capacity under our lines of credit borrowing limits are only restricted by $7.7 million incredit. No outstanding letters of credit.credit are reflected in outstanding short-term debt on our consolidated balance sheets. 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.

2020 BUSINESS OUTLOOK

We are raising our 2020 overall diluted earnings per share guidance range based on our first half financial results and updated view of the anticipated effects of the COVID-19 pandemic on our operating companies. We now expect our 2020 diluted earnings per share to be in the range of $2.10 to $2.30. This improvement is driven by strong first half performance in our Plastics segment along with continued favorable business conditions in this segment expected through the rest of 2020. Also, the impact of COVID-19 on our Electric segment has been less than previously expected. Our 2020 diluted earnings per share guidance includes $0.04 of dilution associated with actual and planned issuances of common shares under our At-the-Market Offering Program and Dividend Reinvestment and Employee Stock Purchase Plans to help fund construction projects at OTP.

We also have taken into consideration strategies for improving future operating results, the cyclical nature of some of our businesses, and current regulatory factors facing our Electric segment. We currently expect capital expenditures for 2020 to be $380 million compared with actual cash used for capital expenditures of $207 million in 2019. Our Electric segment accounts for 96% of our 2020 planned capital expenditures. The increase in our planned expenditures for 2020 is largely driven by the Merricourt and Astoria Station rate base projects. In June 2020, we updated our 2020-2024 anticipated capital expenditures, shifting the timing of expenditures between years and projects as a result of more definitive plans with no material impact on the $1.0 billion five-year expenditure total. A revised five-year anticipated capital expenditures table is provided above on page 45.

Our current assumptions for our updated Business Outlook assume our Electric and Plastics segments are in a gradual recovery as reflected in our updated guidance ranges. Our Manufacturing segment is under a slow recovery. BTD’s customers reduced production levels in the second quarter in response to COVID-19, causing a sharp decline in orders and revenue. We are planning for our Manufacturing segment plants to run at higher levels of capacity in the third and fourth quarters as customer forecasts are indicating increased demand as production plants are being brought back online. We continue to believe our assumptions are reasonable based on current business and economic conditions. We recognize these assumptions may prove to be inaccurate given the recent flare-up in COVID cases, which could result in a further slowing of the broader economic recovery. If our assumptions are not correct and we experience a prolonged negative economic impact from COVID-19, our outlook will be revised accordingly.

Segment components of our revised 2020 diluted earnings per share guidance range compared with 2019 actual earnings and with our previously issued guidance are as follows.

Our latest 2020 guidance issued on August 3, 2020, as compared to earlier guidance issued on May 5, 2020, is summarized below.

Our 2020 guidance for our Electric includes:

CRITICAL ACCOUNTING POLICIES INVOLVING SIGNIFICANT ESTIMATES

o

Capital spending on the Merricourt and Astoria Station rate base projects of $177 million and $81 million, respectively, in 2020. The Merricourt project has rider recovery mechanisms in place in all three state jurisdictions. The Astoria Station project has rider recovery mechanisms in place in South Dakota and North Dakota. This project earns allowance for funds used during construction in Minnesota, has already been approved in our integrated resource plan and is expected to be recovered through a rate case in Minnesota we expect to file in November 2020. The Astoria Station capital project is currently on budget and on schedule, but COVID-19-related disruptions to construction workforce have occurred in the second quarter. The Merricourt project continues to be on budget but is now facing COVID-19-related project delays due to transportation delays of manufactured components for the project. This project is still expected to be completed before December 31, 2020 but could see an increase in costs related to these delays.

48

o

Increased revenues related to $25 million in anticipated capital spending for self-funded generator interconnection agreements.

o

No planned generation plant outages for 2020. Plant outage costs totaled $3.1 million in 2019.

o

The April 2020 decision by the Minnesota Supreme Court in OTP’s favor related to the excess return earned on Federal Energy Regulatory Commission jurisdiction transmission lines. The estimated impact of this decision is an increase to 2020 earnings of $0.05 per share. On a go-forward basis the positive impact of this decision on an annual basis is $0.01 per share. We have updated our Minnesota Transmission Cost Recovery rider filing with new rates incorporating the results of the decision to reflect the effect of this ruling.

o

Implementation of cost reduction efforts such as lower discretionary spending, wage freezes, hiring freezes and reduction in overtime to mitigate the impact of COVID-19. These efforts are expected to positively impact earnings by $0.03 per share.

The above items are offset by:

o

The impact of unfavorable weather during the first quarter of 2020 and anticipated normal weather for the remaining months of 2020. Weather favorably impacted 2019 earnings by $0.08 per share compared to normal.

o

Reductions in commercial and industrial demand related to the negative impacts of COVID-19 as some customers in our jurisdictions have had to either completely shut down operations or curtail operations given reduced demands for their products and services. We also expect to incur increased costs for bad debts, personal protective equipment and the loss of late fee revenue. The total estimated earnings impact of these items ranges from $0.06 per share to $0.08 per share compared with our original estimate of $0.08 per share to $0.12 per share. OTP is working on obtaining regulatory relief to mitigate the impact of COVID-19 on its operating results. It has made joint filings with other investor-owned utilities in all three of its state jurisdictions and has made, or intends to make, additional filings on its own initiating processes for regulatory relief and recovery of current and future COVID-19-related lost commercial and industrial revenues, lost late fees and added expenses for increased bad debts, personal protective equipment and other increased operating and maintenance expenses.

o

Increased expenses caused in large part by a decrease in the discount rate used for the pension plan and a lower rate used for our long-term rate of return. The discount rate for 2020 is 3.47% compared with 4.50% for 2019. For each 25-basis-point decline in the discount rate, pension expense increases approximately $1.0 million. The assumed long-term rate of return for 2020 is 6.88% compared with 7.25% in 2019. Each 25-basis-point decline in this rate equates to approximately $0.7 million in increased pension expense.

o

Higher depreciation and property tax expense due to large capital projects being put into service.

o

Increased interest costs associated with a full year’s interest expense on the $100 million of senior unsecured notes issued in October 2019 and interest on the $35 million and $40 million of senior unsecured notes issued in February and expected to be issued in August of 2020, respectively.

Manufacturing segment earnings will be lower than 2019, driven by the impact of the COVID-19 pandemic:

o

We now estimate a reduction in Manufacturing segment earnings of $0.14 per share from the mid-point of our original segment guidance to the mid-point of our updated segment guidance. This is due to the effects of, and response to, the COVID-19 pandemic.

o

BTD has been impacted by COVID-19-related customer plant shutdowns across all end markets it serves and has cut back on operating levels. In addition to implementing temporary rotating furloughs in the second quarter of 2020 affecting approximately 55% of its employees, BTD reduced its headcount by approximately 180 positions across all its sites in the second quarter of 2020. Additional cost-cutting measures may be taken by BTD depending on the length and severity of this reduced demand for its products as the impacts from COVID-19 and related responses continue.

o

T.O. Plastics’ 2020 earnings are also expected to decline from our original guidance given lower demand and uncertainty across the end markets it serves related to the COVID-19 pandemic. T.O. Plastics may take additional cost-cutting measures depending on the length and severity of market softness for its products as the impact from COVID-19 and related responses continue to develop.

o

Backlog for the Manufacturing segment of approximately $96 million for 2020 compared with $115 million one year ago. Raw material price deflation is driving backlog down by $10 million and the remaining $9 million decrease in backlog is volume driven.

49

We are raising our guidance range in 2020 net income for our Plastics segment and now expect 2020 earnings to be in line with 2019. Sales volumes in 2020 are now forecasted to be approximately 2% higher than 2019 given the strong 2020 first half results and current market conditions. Raw material prices did decrease in the second quarter but are now expected to trend up in the third quarter. This increase is related to suppliers’ plants being busy, tightening of demand and the resin export market strengthening.

Our change in the guidance range for corporate costs, net of tax, is primarily due to the decline in values of our investments in corporate-owned life insurance and investments held at our captive insurance company related to COVID-19 and its related impacts on the stock market. While we have taken expense mitigation efforts to lower our corporate labor and non-labor costs, we do not expect to fully recover the drop in value of our investments before the end of 2020.

Critical Accounting Policies Involving Significant Estimates

The discussion and analysis of the financial statements andour 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 preparationCertain of these consolidated financial statements requiresour accounting policies require 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.

liabilities in the preparation of our consolidated financial statements. We use estimates based on the best information availablehave disclosed 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, interim rate refunds, warranty reserves 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 57 through 59 of our Annual Report on Form 10-K10-K for the year ended December 31, 2019. Aside2020 the critical accounting policies that affect our most significant estimates and assumptions used in preparing our consolidated financial statements. There have been no material changes to our critical accounting policies and estimates from an interim test of goodwill impairment performed for our BTD reporting unit, which is further described below, there werethose disclosed in this Form 10-K.

ITEM 3.QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
There have been no material changes in critical accounting policies or estimates during the quarter ended June 30, 2020.

Goodwill is required to be tested annually for impairment and more frequently if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. Examples of such events or circumstances may include, among others, a significant adverse change in business climate, weakness in an industry in which a reporting unit operates or recent significant cash or operating losses with expectations that those losses will continue. Goodwill is tested for impairment at the reporting unit level. A reporting unit is defined as an operating segment or one level below an operating segment (referred to as a component). A component of an operating segment is a reporting unit if the component constitutes a business for which discrete financial information is available and segment management regularly reviews the operating results of that component.

During the quarter ended March 31, 2020, the Company concluded an interim impairment test of goodwill of its BTD reporting unit, which carries a goodwill balance of $18.1 million, was warranted. This conclusion was reached based on the deteriorating economic conditions resulting from COVID-19 that led to lower product demand across all end markets beginning in the last half of March 2020 and the anticipation of subsequent further reduced demand resulting from temporary plant shutdowns of our original equipment manufacturer customers. In response to this reduced demand, BTD has reduced its operating levels and implemented certain cost reduction efforts, including temporary furloughs of production employees.

We estimated the fair value of the BTD reporting unit primarily using an income approach, which includes a discounted cash flow methodology to arrive at a fair value estimate by determining the present value of projected future cash flows over a specified period plus a terminal value related to cash flows beyond the projection period. The discount rate applied to the estimated future cash flows reflects our estimate of the weighted-average cost of capital of comparable companies. To supplement our income approach, we reference various market indications of fair value, where available. Our market approach includes fair value estimates using multiples derived from comparable enterprise values to EBITDA and revenue multiples, comparable price earnings ratios and, if available, comparable sales transactions for comparative peer companies.

The impairment assessment indicated no impairment was present as the estimated fair value of the reporting unit exceeded the carrying value by approximately 20%. The most significant assumption impacting our fair value estimate under the income approach is the anticipated duration and severity of reduced demand and the resulting impact on revenue levels given the uncertainty of economic conditions in light of COVID-19. Our assumptions included significantly reduced demand in the second quarter of 2020 followed by recovering levels of demand in the third and fourth quarters of 2020. Other significant assumptions included operating expense levels and our ability to manage costs during the anticipated period of reduced demand, the terminal growth rate which impacts estimated cash flow generation beyond our discrete projection period, and the discount rate applied to our estimated future cash flows.

Our estimates and assumptions inherently include a degree of uncertainty, and these estimates and assumptions could be significantly impacted by factors such as the duration and severity of reduced economic activity and industry conditions within the recreational vehicle, lawn and garden, construction, agricultural, and industrial and energy equipment end markets. A significant change in our estimates and assumptions could result in an impairment charge in a future period which could materially impact our results of operations and financial position.

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 materiallyrisk from those discusseddisclosed in forward-looking statements made by or on behalf of the Company. When used in this Form 10-QItem 7A, Quantitative and Qualitative Disclosures About Market Risk, 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. These forward-looking statements involve risks and uncertainties. Actual results may differ materially from those contemplated by the forward-looking statements due to, among other factors, the risks and uncertainties described in the section entitled “Risk Factors” in Part I, Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2019, in Part II, Item 1A2020.

ITEM 4.CONTROLS AND PROCEDURES
Evaluation of our Quarterly Report on Form 10-Q for the quarter ended March 31, 2020, and in Part II, Item 1A of this report on Form 10-Q, as well as the various factors described below:

The economic effects of the COVID-19 outbreak and measures taken to arrest its spread could continue to adversely impact our business, including our results of operations, financial condition and liquidity.

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

Weather impacts, including normal seasonal fluctuation of weather, as well as extreme weather events that could be associated with climate change, could adversely affect our results of operations.

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

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

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 the Company.

We rely on our information systems to conduct our business, and failure to protect these systems against security breaches or cyber-attacks could adversely affect our business and results of operations. Additionally, if these systems fail or become unavailable for any significant period, our business could be harmed.

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 our businesses through capital projects, including infrastructure and new technology additions, or to grow or realign our businesses through acquisitions or dispositions may not be successful, which could result in poor financial performance.

We may, from time to time, sell assets to provide capital to fund investments in our electric utility business or for other corporate purposes, which could result in the recognition of a loss on the sale of any assets sold and other potential liabilities. The sale of any of our businesses also exposes us to additional risks associated with indemnification obligations under the applicable sales agreements and any related disputes.

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

We are subject to risks associated with energy markets.

Changes in tax laws, as well as judgments and estimates used in the determination of tax-related asset and liability amounts, could materially adversely affect our business, financial condition, results of operations and prospects.

Four of our operating companies have single customers that provide a significant portion of the individual operating company’s and the business segment’s revenue. The loss of, or significant reduction in revenue from, any one of these customers would have a significant negative financial impact on the operating company and its business segment and could have a significant negative financial impact on the Company.

The inability to attract and retain a qualified workforce including, but not limited to, executive officers, key employees and employees with specialized skills could have an adverse effect on our operations.

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

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

OTP’s operations are subject to an extensive legal and regulatory framework under federal and state laws as well as regulations imposed by other organizations that may have a negative impact on our business and results of operations.

OTP’s electric transmission and generation facilities could be vulnerable to cyber and physical attack that could impair our ability to provide electrical service to our customers or disrupt the U.S. bulk power system.

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

Regulation of generating plant emissions could affect our operating costs and the costs of supplying electricity to our customers and the economic viability of continued operation of certain of OTP’s steam-powered electric plants.

The long-range planning required for transmission and generation projects creates risks of increased costs and lower returns on investment when the project is finally completed.

Competition from foreign and domestic manufacturers, the price and availability of raw materials, trade policy and tariffs affecting prices and markets for raw material and manufactured products, prices and supply of scrap or recyclable material and general economic conditions could affect the revenues and earnings of our manufacturing businesses.

Economic conditions in the industries in which our customers operate can have an adverse impact on our results of operations and cash flows.

Our business and operating results may be adversely affected if we are not able to maintain our manufacturing, engineering and technological expertise.

Our manufacturing, painting and coating operations are subject to environmental, health and safety laws and regulations that could result in liabilities to us.

Our plastics operations are highly dependent on a limited number of vendors for PVC resin and a limited supply of PVC resin. The loss of a key vendor, or any interruption or delay in the supply of PVC resin, could result in reduced sales or increased costs for our plastics business.

We compete against many other manufacturers of PVC pipe and manufacturers of alternative products. Customers may not distinguish our products from those of our competitors.

Changes in PVC resin prices can negatively affect our plastics business.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

At June 30, 2020 we had exposure to market risk associated with interest rates because we had $41.2 million in short-term debt outstanding subject to variable interest rates indexed to LIBOR plus 1.50% under the OTC Credit Agreement.

All of our remaining consolidated long-term debt outstanding on June 30, 2020 has fixed interest rates. 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.

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.

The companies in our Manufacturing segment are exposed to market risk related to changes in commodity prices for steel, aluminum, and polystyrene and other plastics resins. The price and availability of these raw materials could affect the revenues and earnings of our Manufacturing segment.

The PVC pipe companies are exposed to market risk related to changes in commodity prices for 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 volume 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.

Item 4. Controls and Procedures

.Under the supervision and with the participation of companythe Company’s management, including ourthe Chief Executive Officer and the Chief Financial Officer, we evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934 as amended (the Exchange Act)) as of June 30, 2020,March 31, 2021, the end of the period covered by this report. Based on that evaluation, ourthe Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of June 30, 2020.

During the fiscal quarter ended June 30, 2020, thereMarch 31, 2021.

Changes in Internal Control over Financial Reporting. There were no changes in our internal control over financial reporting (as defined in RuleRules 13a-15(f) under the Exchange Act) during the quarter ended March 31, 2021 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

ITEM 6.EXHIBITS
The following Exhibits are filed as part of, operations, financial condition and liquidity.

The outbreak and global spread of COVID-19, which has been declared a pandemicor incorporated by the World Health Organization, has adversely impacted economic activity and conditions worldwide and is currently impacting our business operations. The extent to which COVID-19 will continue to impact our business is highly uncertain and will depend on future developments and the extent of federal, state and local government responses affecting economic recovery. In particular, the COVID-19 pandemic could, among other things:

reference into, this report.

further reduce customer demand in our Manufacturing segment, where we have experienced a significant decline in orders as many of our customers are in businesses impacted by the pandemic and have temporarily closed their plants, and where we have already taken steps to reduce our operations, including furloughing of employees and eliminating positions;

reduce customer demand in our Electric segment, including demand from commercial and industrial customers;

 No.

Description
31.1

result in lower PVC pipe sales due to potential delays or cancellation of public water and wastewater infrastructure projects caused by funding shortfalls;

lead to disruptions of our workforce;

force us to temporarily close certain plants or construction sites if precautions to prevent the spread of the virus at those locations are not effective;

increase our bad debt expenses, particularly in our Electric segment;

increase our future pension benefit cost and funding requirements;

increase health insurance premiums;

disrupt the supply chains, delivery systems or construction workforce related to our Electric segment capital expenditure plans, including our Merricourt and Astoria Station projects, resulting in further delays and increased costs;

disrupt global financial markets, reducing our ability to access capital necessary to finance such expenditures, and which could in the future negatively affect our liquidity; and

result in a recession or market correction that could materially affect our business and the value of our common stock.

We continue to monitor developments involving our workforce, customers, construction contractors, suppliers and vendors and take steps to mitigate against additional impacts, but given the unprecedented and dynamic nature of these circumstances, we cannot predict the full extent of the impact that COVID-19 will have on our results of operations, financial condition and liquidity. The situation continues to change, and the magnitude of the impact will depend, in part, on the length and severity of the pandemic. However, the effects could have a material impact on our results of operations, financial condition and liquidity and heighten many of the known risks described under Part I, Item 1A, “Risk Factors” on pages 29 through 39 of our Annual Report on Form 10-K for the year ended December 31, 2019.
