The full development of this approximately 300 MW wind project would involve the sale of energy to corporate customers under long-term power sales agreements.

Non-Controlling Interest in Subsidiaries. Non-controlling interest in subsidiaries on the Consolidated Balance Sheet and net loss attributable to non-controlling interest on the Consolidated Statement of Income represent the portion of equity ownership and earnings, respectively, of subsidiaries that are not attributable to equity holders of ALLETE. These amounts as of and during the three months ended March 31, 2020, related to the tax equity financing structure for ALLETE Clean Energy’s 106 MW Glen Ullin wind energy facility.

On April 16, 2020, ALLETE Clean Energy commenced operations of South Peak, an 80 MW wind energy facility in Montana, and on April 29, 2020, received approximately $70 million in cash from a third-party investor as part of a tax equity financing for the wind energy facility.

Subsequent Events. The Company performed an evaluation of subsequent events for potential recognition and disclosure through the date of the financial statements issuance.

New Accounting Pronouncements.

Credit Losses. In 2016, the FASB issued an accounting standard update that requires entities to recognize an allowance for expected credit losses for financial instruments within its scope. Examples of financial instruments within the scope include trade receivables, certain financial guarantees, and held-to-maturity debt securities. The allowance for expected credit losses should be based on historical information, current conditions and reasonable and supportable forecasts. The new standard also revises the other-than-temporary impairment model for available-for-sale debt securities. The new guidance became effective January 1, 2020, and was adopted by the Company in the first quarter of 2020. Adoption of this standard did not have a material impact on our Consolidated Financial Statements.

NOTE 2. REGULATORY MATTERS

Regulatory matters are summarized in Note 4. Regulatory Matters to the Consolidated Financial Statements in our 2019 Form 10‑K, with additional disclosure provided in the following paragraphs.

Electric Rates. Entities within our Regulated Operations segment file for periodic rate revisions with the MPUC, PSCW or FERC. As authorized by the MPUC, Minnesota Power also recognizes revenue under cost recovery riders for transmission, renewable, and environmental investments and expenditures. Revenue from cost recovery riders was $9.6 million for the three months ended March 31, 2020 ($7.4 million for three months ended March 31, 2019).

2020 Minnesota General Rate Case. On November 1, 2019, Minnesota Power filed a retail rate increase request with the MPUC seeking an average increase of approximately 10.6 percent for retail customers. The rate filing seeks a return on equity of 10.05 percent and a 53.81 percent equity ratio. On an annualized basis, the requested final rate increase would generate approximately $66 million in additional revenue. In orders dated December 23, 2019, the MPUC accepted the filing as complete and authorized an annual interim rate increase of $36.1 million that began January 1, 2020. We cannot predict the level of final rates that may be authorized by the MPUC.

On April 23, 2020, Minnesota Power filed a request with the MPUC that proposes a resolution for Minnesota Power’s 2020 general rate case. Key components of our proposal include removing the current power marketing margin credit in base rates and reflecting actual power marketing margins in the fuel adjustment clause effective May 1, 2020; refunding to customers interim rates collected through April 2020 of approximately $12 million ($9 million as of March 31, 2020,); increasing ongoing customer rates 4.1 percent compared to the 5.8 percent increase reflected in current interim rates; and a provision that Minnesota Power would not file another rate case until at least March 1, 2021, unless certain events occur. Minnesota Power would withdraw its general rate case upon approval of this filing and proposed resolution by the MPUC. At a hearing on April 30, 2020, the MPUC approved lowering current interim rates to 4.1 percent effective May 1, 2020, as requested by Minnesota Power in this filing. A final decision on Minnesota Power’s full proposal in this filing is expected in June 2020. At this time, we are unable to predict whether the MPUC will ultimately approve this filing and proposed resolution, and thus, as of March 31, 2020, we have not recorded reserves for interim rates.

NOTE 2. REGULATORY MATTERS (Continued)

Electric Rates (Continued)

Transmission Cost Recovery Rider. Minnesota Power has an approved cost recovery rider in place for certain transmission investments and expenditures. In a 2016 order, the MPUC approved Minnesota Power’s updated customer billing rates allowing Minnesota Power to charge retail customers on a current basis for the costs of constructing certain transmission facilities plus a return on the capital invested. On July 9, 2019, Minnesota Power filed a petition seeking MPUC approval to update the customer billing factor to include investments made for the GNTL. (See Note 6. Commitments, Guarantees and Contingencies.)

Renewable Cost Recovery Rider. Minnesota Power has an approved cost recovery rider for certain renewable investments and expenditures. The cost recovery rider allows Minnesota Power to charge retail customers on a current basis for the costs of certain renewable investments plus a return on the capital invested. Current customer billing rates for the renewable cost recovery rider were approved by the MPUC in a November 2018 order. On August 15, 2019, Minnesota Power filed a petition seeking MPUC approval to update the customer billing factor.

Fuel Adjustment Clause Reform. In a 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. 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 May 1, 2019, Minnesota Power filed its fuel adjustment forecast for 2020, which was accepted by the MPUC in an order dated November 14, 2019, for purposes of setting fuel adjustment clause rates for 2020, subject to a true-up filing in 2021.

COVID-19 Related Costs. In an order dated March 24, 2020, the PSCW authorized public utilities, which includes SWL&P, to defer expenditures incurred by the utility resulting from its compliance with state government or regulator orders, and as otherwise required to ensure the provision of safe, reliable and affordable access to utility services during Wisconsin’s declared public health emergency for COVID-19. On April 20, 2020, Minnesota Power along with other regulated electric and natural gas service providers in Minnesota filed a joint petition to request MPUC authorization to track incremental costs and expenses incurred as a result of COVID-19, and to defer and record such costs as a regulatory asset, subject to recovery in a future proceeding. 

Integrated Resource Plan. In a 2016 order, the MPUC approved Minnesota Power’s 2015 IRP with modifications. The order accepted Minnesota Power’s plans for the economic idling of Taconite Harbor Units 1 and 2 and the ceasing of coal-fired operations at Taconite Harbor in 2020, directed Minnesota Power to retire Boswell Units 1 and 2 no later than 2022, required an analysis of generation and demand response alternatives to be filed with a natural gas resource proposal, and required Minnesota Power to conduct requests for proposal for additional wind, solar and demand response resource additions. Minnesota Power retired Boswell Units 1 and 2 in the fourth quarter of 2018. Minnesota Power’s next IRP filing is due October 1, 2020.

Nemadji Trail Energy Center. In 2017, Minnesota Power submitted a resource package to the MPUC which included requesting approval of a 250 MW natural gas capacity dedication agreement. The natural gas capacity dedication agreement was subject to MPUC approval of the construction of NTEC, a 525 MW to 550 MW combined-cycle natural gas‑fired generating facility which will be jointly owned by Dairyland Power Cooperative and a subsidiary of ALLETE. Minnesota Power would purchase approximately 50 percent of the facility's output starting in 2025. In an order dated January 24, 2019, the MPUC approved Minnesota Power’s request for approval of the NTEC natural gas capacity dedication agreement. Separately, the MPUC required a baseload retirement evaluation in Minnesota Power’s next IRP filing analyzing its existing fleet, including potential early retirement scenarios of Boswell Units 3 and 4, as well as a securitization plan. On December 23, 2019, the Minnesota Court of Appeals reversed and remanded the MPUC’s decision to approve certain affiliated-interest agreements. The MPUC was ordered to determine whether NTEC may have the potential for significant environmental effects and, if so, to prepare an environmental assessment worksheet before reassessing the agreements. On January 22, 2020, Minnesota Power filed a petition for further review with the Minnesota Supreme Court requesting that it review and overturn the Minnesota Court of Appeals decision, which petition was accepted for review by the Minnesota Supreme Court on March 18, 2020. On January 8, 2019, an application for a certificate of public convenience and necessity for NTEC was submitted to the PSCW, which was approved by the PSCW at a hearing on January 16, 2020. Construction of NTEC is subject to obtaining additional permits from local, state and federal authorities. The total project cost is estimated to be approximately $700 million, of which ALLETE’s portion is expected to be approximately $350 million. ALLETE’s portion of NTEC project costs incurred through March 31, 2020, is approximately $13 million.

MISO Return on Equity Complaint. MISO transmission owners, including ALLETE and ATC, have an authorized return on equity of 9.88 percent, or 10.38 percent including an incentive adder for participation in a regional transmission organization, based on a November 2019 FERC order. In this order, the FERC reduced the base return on equity for regional transmission organizations as recommended by an administrative law judge with refunds ordered for prior periods, which are immaterial to ALLETE. Multiple parties to the complaint have filed requests for rehearing of the FERC order.

NOTE 2. REGULATORY MATTERS (Continued)

Regulatory Assets and Liabilities. Our regulated utility operations are subject to accounting guidance for the effect of certain types of regulation. Regulatory assets represent incurred costs that have been deferred as they are probable for recovery in customer rates. Regulatory liabilities represent obligations to make refunds to customers and amounts collected in rates for which the related costs have not yet been incurred. The Company assesses quarterly whether regulatory assets and liabilities meet the criteria for probability of future recovery or deferral. With the exception of the regulatory asset for Boswell Units 1 and 2 net plant and equipment, no other regulatory assets are currently earning a return. The recovery, refund or credit to rates for these regulatory assets and liabilities will occur over the periods either specified by the applicable regulatory authority or over the corresponding period related to the asset or liability.

NOTE 3. EQUITY INVESTMENTS

Investment in ATC. Our wholly-owned subsidiary, ALLETE Transmission Holdings, owns approximately 8 percent of ATC, a Wisconsin-based utility that owns and maintains electric transmission assets in portions of Wisconsin, Michigan, Minnesota and Illinois. We account for our investment in ATC under the equity method of accounting. In the three months ended March 31, 2020, we invested $0.4 million in ATC, and on April 30, 2020, we invested an additional $0.8 million. We expect to make additional investments of $1.6 million in 2020.

Investment in Nobles 2. Our wholly-owned subsidiary, ALLETE South Wind, owns 49 percent of Nobles 2, the entity that will own and operate a 250 MW wind energy facility in southwestern Minnesota pursuant to a 20-year PPA with Minnesota Power. We account for our investment in Nobles 2 under the equity method of accounting. As of March 31, 2020, our equity investment in Nobles 2 was $83.4 million ($56.0 million at December 31, 2019). In the three months ended March 31, 2020, we invested $27.4 million in Nobles 2, and in April 2020 we invested an additional $21.7 million. We expect to make approximately $65 million in additional investments in 2020.

NOTE 4. FAIR VALUE

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). We utilize market data or assumptions that market participants would use in pricing the asset or liability, including assumptions about risk and the risks inherent in the inputs to the valuation technique. These inputs can be readily observable, market corroborated or generally unobservable. We primarily apply the market approach for recurring fair value measurements and endeavor to utilize the best available information. Accordingly, we utilize valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. These inputs, which are used to measure fair value, are prioritized through the fair value hierarchy. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurement) and the lowest priority to unobservable inputs (Level 3 measurement). Descriptions of the three levels of the fair value hierarchy are discussed in Note 7. Fair Value to the Consolidated Financial Statements in our 2019 Form 10-K.

The following tables set forth, by level within the fair value hierarchy, our assets and liabilities that were accounted for at fair value on a recurring basis as of March 31, 2020, and December 31, 2019. Each asset and liability is classified based on the lowest level of input that is significant to the fair value measurement. Our assessment of the significance of a particular input to the fair value measurement requires judgment, which may affect the valuation of these assets and liabilities and their placement within the fair value hierarchy levels. The estimated fair value of Cash and Cash Equivalents listed on the Consolidated Balance Sheet approximates the carrying amount and therefore is excluded from the recurring fair value measures in the following tables.

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis. Non-financial assets such as equity method investments, land inventory, and property, plant and equipment are measured at fair value when there is an indicator of impairment and recorded at fair value only when an impairment is recognized. For the three months ended March 31, 2020, and the year ended December 31, 2019, there were no indicators of impairment for these non-financial assets.

We had $66.3 million outstanding in standby letters of credit and $0.2 million in outstanding draws under our lines of credit as of March 31, 2020 ($62.0 million in standby letters of credit and no outstanding draws as of December 31, 2019).

On January 10, 2020, ALLETE entered into a $200 million unsecured term loan agreement (Term Loan) of which we have borrowed $110 million as of March 31, 2020. The Term Loan provides for the ability to borrow up to an additional $90 million, is due on February 10, 2021, and may be repaid at any time. Interest is payable monthly at a rate per annum equal to LIBOR plus 0.55 percent. Proceeds from the Term Loan will be used for construction-related expenditures.

On March 26, 2020, ALLETE agreed to sell first mortgage bonds (Bonds) to certain institutional buyers in the private placement market, which will be issued on or before August 3, 2020, in two series as follows:

Maturity Date	Principal Amount	Interest Rate
August 1, 2030	$46 Million	2.50%
August 1, 2050	$94 Million	3.30%

ALLETE will have the option to prepay all or a portion of the Bonds at its discretion, subject to a make-whole provision. The Bonds will be subject to additional terms and conditions which are customary for these types of transactions. ALLETE plans to use the proceeds from the sale of the Bonds to fund utility capital investment and for general corporate purposes. The Bonds will be sold in reliance on an exemption from registration under Section 4(a)(2) of the Securities Act of 1933, as amended, to institutional accredited investors.

On April 8, 2020, ALLETE entered into a $115 million unsecured term loan agreement (Term Loan) and borrowed $95 million upon execution. The Term Loan provides for an additional draw of $20 million on or after July 1, 2020. The Term Loan is due on April 7, 2021, and may be repaid at any time. Interest is payable monthly at a rate per annum equal to LIBOR plus 1.7 percent with a LIBOR floor of 0.75 percent. Proceeds from the Term Loan will be used for general corporate purposes.

Financial Covenants. Our long-term debt arrangements contain customary covenants. In addition, our lines of credit and letters of credit supporting certain long-term debt arrangements contain financial covenants. Our compliance with financial covenants is not dependent on debt ratings. The most restrictive financial covenant requires ALLETE to maintain a ratio of indebtedness to total capitalization (as the amounts are calculated in accordance with the respective long-term debt arrangements) of less than or equal to 0.65 to 1.00, measured quarterly. As of March 31, 2020, our ratio was approximately 0.43 to 1.00. Failure to meet this covenant would give rise to an event of default if not cured after notice from the lender, in which event ALLETE may need to pursue alternative sources of funding. Some of ALLETE’s debt arrangements contain “cross-default” provisions that would result in an event of default if there is a failure under other financing arrangements to meet payment terms or to observe other covenants that would result in an acceleration of payments due. ALLETE has no significant restrictions on its ability to pay dividends from retained earnings or net income. As of March 31, 2020, ALLETE was in compliance with its financial covenants.

NOTE 6. COMMITMENTS, GUARANTEES AND CONTINGENCIES

Power Purchase and Sale Agreements. Our long-term PPAs have been evaluated under the accounting guidance for variable interest entities. We have determined that either we have no variable interest in the PPAs or, where we do have variable interests, we are not the primary beneficiary; therefore, consolidation is not required. These conclusions are based on the fact that we do not have both control over activities that are most significant to the entity and an obligation to absorb losses or receive benefits from the entity’s performance. Our financial exposure relating to these PPAs is limited to our capacity and energy payments.

Our PPAs are summarized in Note 9. Commitments, Guarantees and Contingencies to the Consolidated Financial Statements in our 2019 Form 10-K, with additional disclosure provided in the following paragraphs.

Square Butte PPA. As of March 31, 2020, Square Butte had total debt outstanding of $276.2 million. Fuel expenses are recoverable through Minnesota Power’s fuel adjustment clause and include the cost of coal purchased from BNI Energy under a long-term contract. Minnesota Power’s cost of power purchased from Square Butte during the three months ended March 31, 2020, was $20.1 million ($20.5 million for the same period in 2019). This reflects Minnesota Power’s pro rata share of total Square Butte costs based on the 50 percent output entitlement. Included in this amount was Minnesota Power’s pro rata share of interest expense of $1.9 million ($2.1 million for the same period in 2019). Minnesota Power’s payments to Square Butte are approved as a purchased power expense for ratemaking purposes by both the MPUC and the FERC.

Minnkota Power PSA. Minnesota Power has a PSA with Minnkota Power, which commenced in 2014. Under the PSA, Minnesota Power is selling a portion of its entitlement from Square Butte to Minnkota Power, resulting in Minnkota Power’s net entitlement increasing and Minnesota Power’s net entitlement decreasing until Minnesota Power’s share is eliminated at the end of 2025. Of Minnesota Power’s 50 percent output entitlement, it sold to Minnkota Power approximately 28 percent in 2020 and in 2019.

Minnesota Power Short-term PSAs. Minnesota Power has entered into various short-term PSAs to sell 300 MW of energy in 2020 and 2021. These PSAs were entered into to proactively mitigate the uncertainty of customers’ energy needs and potential load loss due to the COVID-19 pandemic. Additional transactions, purchases or sales, could be entered into as the extent and duration of the COVID-19 pandemic becomes known.

Coal, Rail and Shipping Contracts. Minnesota Power has coal supply agreements providing for the purchase of a significant portion of its coal requirements through December 2021. Minnesota Power also has coal transportation agreements in place for the delivery of a significant portion of its coal requirements through December 2021. The costs of fuel and related transportation costs for Minnesota Power’s generation are recoverable from Minnesota Power’s utility customers through the fuel adjustment clause.

Transmission. We continue to make investments in transmission opportunities that strengthen or enhance the transmission grid or take advantage of our geographical location between sources of renewable energy and end users. These include the GNTL, investments to enhance our own transmission facilities, investments in other transmission assets (individually or in combination with others) and our investment in ATC.

Great Northern Transmission Line. As a condition of the 250-MW long-term PPA entered into with Manitoba Hydro, construction of additional transmission capacity is required. As a result, Minnesota Power is constructing the GNTL, an approximately 220‑mile 500-kV transmission line between Manitoba and Minnesota’s Iron Range that was proposed by Minnesota Power and Manitoba Hydro in order to strengthen the electric grid, enhance regional reliability and promote a greater exchange of sustainable energy.

In a 2016 order, the MPUC approved the route permit for the GNTL, and in 2016, the U.S. Department of Energy issued a presidential permit to cross the U.S.-Canadian border, which was the final major regulatory approval needed before construction in the U.S. could begin. Construction activities commenced in the first quarter of 2017, and Minnesota Power expects the GNTL to be in-service by mid-2020. The total project cost in the U.S., including substation work, is estimated to be approximately $700 million, of which Minnesota Power’s portion is expected to be approximately $325 million; the difference will be recovered from a subsidiary of Manitoba Hydro as non-shareholder contributions to capital. Total project costs of $647.7 million have been incurred through March 31, 2020, of which $344.6 million has been recovered from a subsidiary of Manitoba Hydro.

In June 2019, Manitoba Hydro announced the Canadian federal government’s approval of the MMTP project and in August 2019, the Canadian National Energy Board granted final pre-construction approvals. Construction on the MMTP commenced in the third quarter of 2019. On April 16, 2020, Manitoba Hydro announced that construction of the MMTP was complete and that testing and commissioning of the line, communications equipment and substation will take place to meet the anticipated in-service deadline of June 1, 2020. The MMTP is still subject to legal challenges which Minnesota Power is actively monitoring.

NOTE 6. COMMITMENTS, GUARANTEES AND CONTINGENCIES (Continued)

Transmission (Continued)

Construction of Manitoba Hydro’s Keeyask hydroelectric generation facility, which will provide the power to be sold under PPAs with Minnesota Power and transmitted on the MMTP and the GNTL, commenced in 2014 and is anticipated to be completely in-service by early 2021.

Environmental Matters.

Our businesses are subject to regulation of environmental matters by various federal, state and local authorities. A number of regulatory changes to the Clean Air Act, the Clean Water Act and various waste management requirements have been promulgated by both the EPA and state authorities over the past several years. Minnesota Power’s facilities are subject to additional requirements under many of these regulations. Minnesota Power is reshaping its generation portfolio, over time, to reduce its reliance on coal, has installed cost-effective emission control technology, and advocates for sound science and policy during rulemaking implementation.

We consider our businesses to be in substantial compliance with currently applicable environmental regulations and believe all necessary permits have been obtained. We anticipate that with many state and federal environmental regulations and requirements finalized, or to be finalized in the near future, potential expenditures for future environmental matters may be material and require significant capital investments. Minnesota Power has evaluated various environmental compliance scenarios using possible outcomes of environmental regulations to project power supply trends and impacts on customers.

We review environmental matters on a quarterly basis. Accruals for environmental matters are recorded when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated based on current law and existing technologies. Accruals are adjusted as assessment and remediation efforts progress, or as additional technical or legal information becomes available. Accruals for environmental liabilities are included in the Consolidated Balance Sheet at undiscounted amounts and exclude claims for recoveries from insurance or other third parties. Costs related to environmental contamination treatment and cleanup are expensed unless recoverable in rates from customers.

Air. The electric utility industry is regulated both at the federal and state level to address air emissions. Minnesota Power’s generating facilities mainly burn low-sulfur western sub-bituminous coal. All of Minnesota Power’s coal-fired generating facilities are equipped with pollution control equipment such as scrubbers, baghouses and low NO_X technologies. Under currently applicable environmental regulations, these facilities are substantially compliant with emission requirements.

Cross-State Air Pollution Rule (CSAPR). The CSAPR requires certain states in the eastern half of the U.S., including Minnesota, to reduce power plant emissions that contribute to ozone or fine particulate pollution in other states. The CSAPR does not require installation of controls but does require facilities have sufficient allowances to cover their emissions on an annual basis. These allowances are allocated to facilities from each state’s annual budget, and can be bought and sold. Based on our review of the NO_x and SO₂ allowances issued and pending issuance, we currently expect generation levels and emission rates will result in continued compliance with the CSAPR.

National Ambient Air Quality Standards (NAAQS). The EPA is required to review the NAAQS every five years. If the EPA determines that a state’s air quality is not in compliance with the NAAQS, the state is required to adopt plans describing how it will reduce emissions to attain the NAAQS. None of the compliance costs for proposed or current NAAQS revisions are expected to be material.

Climate Change. The scientific community generally accepts that emissions of GHG are linked to global climate change which creates physical and financial risks. Physical risks could include, but are not limited to: increased or decreased precipitation and water levels in lakes and rivers; increased temperatures; and changes in the intensity and frequency of extreme weather events. These all have the potential to affect the Company’s business and operations. We are addressing climate change by taking the following steps that also ensure reliable and environmentally compliant generation resources to meet our customers’ requirements:

• Expanding renewable power supply for both our operations and the operations of others;

• Providing energy conservation initiatives for our customers and engaging in other demand side management efforts;

• Improving efficiency of our generating facilities;

• Supporting research of technologies to reduce carbon emissions from generating facilities and carbon sequestration efforts;

• Evaluating and developing less carbon intensive future generating assets such as efficient and flexible natural gas-fired generating facilities;

• Managing vegetation on right-of-way corridors to reduce potential wildfire or storm damage risks; and

• Practicing sound forestry management in our service territories to create landscapes more resilient to disruption from climate-related changes, including planting and managing long-lived conifer species.

EPA Regulation of GHG Emissions. On June 19, 2019, the EPA finalized several separate rulemakings regarding regulating carbon emissions from electric utility generating units.

The EPA repealed the Clean Power Plan (CPP), following a determination by the EPA that the CPP exceeded the EPA’s statutory authority under the Clean Air Act (CAA). The primary reason for this was that the CPP attempted to regulate electric generating unit’s carbon emissions through measures outside of the affected unit’s direct control. The CPP was first announced as a proposed rule under Section 111(d) of the Clean Air Act for existing power plants entitled “Carbon Pollution Emission Guidelines for Existing Stationary Sources: Electric Generating Units”.

With the repeal of the CPP, the Affordable Clean Energy Rule was finalized. The rule establishes emissions guidelines for states to use when developing plans to limit carbon dioxide at coal-fired power plants. The rule identifies heat rate improvements made at individual units as the best system of emission reduction. Affected facilities for Minnesota Power include Boswell Units 3 and 4. Based on our initial review of the rule, many of the candidate heat rate improvements are already installed on Boswell Units 3 and 4 and the currently economically idled Taconite Harbor 1 and 2.

Additionally, the EPA finalized new regulations for the state implementation of the Affordable Clean Energy Rule and any future emission guidelines issued under CAA Section 111(d). States will have three years to submit State Implementation Plans (SIPs), and the EPA has 12 months to review and approve those plans. Since the Affordable Clean Energy Rule allows states considerable flexibility in how to best implement its requirements, Minnesota Power plans to work closely with the MPCA and the Minnesota Department of Commerce, who are currently co-reviewing the rule as the state develops its SIP. If a state does not submit a SIP or submits a SIP that is unacceptable to the EPA, the EPA will develop a Federal Implementation Plan. The MPCA currently plans to develop a SIP for the Affordable Clean Energy Rule.

Minnesota had already initiated several measures consistent with those called for under the now repealed CPP and finalized Affordable Clean Energy Rule. Minnesota Power continues implementing its EnergyForward strategic plan that provides for significant emission reductions and diversifying its electricity generation mix to include more renewable and natural gas energy. (See Note 2. Regulatory Matters.) We are unable to predict the GHG emission compliance costs we might incur as a result of the Affordable Clean Energy Rule and the resulting SIP; however, the costs could be material. Minnesota Power would seek recovery of additional costs through a rate proceeding.

Water. The Clean Water Act requires NPDES permits be obtained from the EPA (or, when delegated, from individual state pollution control agencies) for any wastewater discharged into navigable waters. We have obtained all necessary NPDES permits, including NPDES storm water permits for applicable facilities, to conduct our operations.

Steam Electric Power Generating Effluent Limitations Guidelines. In 2015, the EPA issued revised federal effluent limitation guidelines (ELG) for steam electric power generating stations under the Clean Water Act. It set effluent limits and prescribed BACT for several wastewater streams, including flue gas desulphurization (FGD) water, bottom ash transport water and coal combustion landfill leachate. In 2017, the EPA announced a two-year postponement of the ELG compliance date of November 1, 2018, to November 1, 2020, while the agency reconsiders the bottom ash transport water and FGD wastewater provisions. On April 12, 2019, the U.S. Court of Appeals for the Fifth Circuit vacated and remanded back to the EPA portions of the ELG that allowed for continued discharge of legacy wastewater and leachate. On November 22, 2019, the EPA published a draft rulemaking that proposes to allow re-use of bottom ash transport water in FGD scrubber systems with minor discharges related to maintaining system water balance. The proposed rulemaking would also allow future discharge of FGD wastewater discharge provided it meets new BACT standards. A final rulemaking is anticipated in mid to late 2020.

The ELG's potential impact on Minnesota Power operations is primarily at Boswell. Boswell currently discharges bottom ash contact water through its NPDES permit, and also has a closed-loop FGD system that does not discharge to surface waters, but may do so in the future if additional water treatment measures are implemented. Under the current ELG rule, bottom ash transport water discharge to surface waters must cease no later than December 31, 2023. Bottom ash contact water will either need to be re-used in a closed-loop process, routed to a FGD scrubber, or the bottom ash handling system will need to be converted to a dry process. The ELG rule provision regarding these two waste-streams are being reconsidered and may change prior to November 1, 2020. Efforts have been underway at Boswell to reduce the amount of water discharged and evaluate potential re-use options in its plant processes. The EPA’s additional reconsideration of legacy wastewater discharge requirements have the potential to reduce time lines for dewatering Boswell’s existing bottom ash pond. The timing of a draft rule addressing legacy wastewater and leachate is currently unknown.

At this time, we cannot estimate what compliance costs we might incur related to these or other potential future water discharge regulations; however, the costs could be material, including costs associated with retrofits for bottom ash handling, pond dewatering, pond closure, and wastewater treatment and re-use. Minnesota Power would seek recovery of additional costs through a rate proceeding.

Solid and Hazardous Waste. The Resource Conservation and Recovery Act of 1976 regulates the management and disposal of solid and hazardous wastes. We are required to notify the EPA of hazardous waste activity and, consequently, routinely submit reports to the EPA.

Coal Ash Management Facilities. Minnesota Power stores or disposes coal ash at four of its electric generating facilities by the following methods: storing ash in clay-lined onsite impoundments (ash ponds), disposing of dry ash in a lined dry ash landfill, applying ash to land as an approved beneficial use and trucking ash to state permitted landfills.

Coal Combustion Residuals from Electric Utilities (CCR). In 2015, the EPA published the final rule regulating CCR as nonhazardous waste under Subtitle D of the Resource Conservation and Recovery Act (RCRA) in the Federal Register. The rule includes additional requirements for new landfill and impoundment construction as well as closure activities related to certain existing impoundments. Costs of compliance for Boswell and Laskin are expected to occur primarily over the next 15 years and be between approximately $65 million and $120 million. Compliance costs for CCR at Taconite Harbor are not expected to be material. Minnesota Power would seek recovery of additional costs through a rate proceeding.

Minnesota Power continues to work on minimizing costs through evaluation of beneficial re-use and recycling of CCR and CCR‑related waters. In 2017, the EPA announced its intention to formally reconsider the CCR rule under Subtitle D of the RCRA and in March 2018, published the first phase of the proposed rule revisions in the Federal Register. In July 2018, the EPA finalized revisions to elements of the CCR rule, including extending certain deadlines by two years, the establishment of alternative groundwater protection standards for certain constituents and the potential for risk-based management options at facilities based on site characteristics. In August 2018, a U.S. District Court for the District of Columbia decision vacated specific provisions of the CCR rule. The court decision changed the status of three existing impoundments at Boswell that must now be considered unlined. The EPA proposed additional rule revisions in August and December 2019 to address outstanding issues from litigation and closure timelines for unlined impoundments, respectively. These rules are anticipated to be finalized in 2020 and could impact the timing of closure activities for Boswell’s three impoundments. Additionally, the EPA recently released a proposed Part B rulemaking that addresses options for beneficial reuse of CCR materials, alternative liner demonstrations, and other CCR regulatory revisions. Compliance costs at Boswell due to the court decision are unknown at this time. Minnesota Power would seek recovery of additional costs through a rate proceeding.

Other Environmental Matters

Manufactured Gas Plant Site. We are reviewing and addressing environmental conditions at a former manufactured gas plant site located in Superior, Wisconsin. SWL&P has been working with the Wisconsin Department of Natural Resources (WDNR) in determining the extent of contamination at the site and surrounding properties. In December 2017, the WDNR authorized SWL&P to transition from site investigation into the remedial design process. As of March 31, 2020, we have recorded a liability of approximately $7 million for remediation costs at this site (approximately $7 million as of December 31, 2019). SWL&P has also recorded an associated regulatory asset as we expect recovery of these remediation costs to be allowed by the PSCW. Remediation costs are expected to be incurred through 2023.

Other Matters.

ALLETE Clean Energy. ALLETE Clean Energy’s wind energy facilities have PSAs in place for their entire output and expire in various years between 2022 and 2039. As of March 31, 2020, ALLETE Clean Energy has $59.6 million outstanding in standby letters of credit, the majority of which are held as security under these PSAs and PSAs for wind energy facilities under development.

BNI Energy. As of March 31, 2020, BNI Energy had surety bonds outstanding of $67.7 million related to the reclamation liability for closing costs associated with its mine and mine facilities. Although its coal supply agreements obligate the customers to provide for the closing costs, additional assurance is required by federal and state regulations. BNI Energy’s total reclamation liability is currently estimated at $67.3 million. BNI Energy does not believe it is likely that any of these outstanding surety bonds will be drawn upon.

ALLETE Properties. As of March 31, 2020, ALLETE Properties had surety bonds outstanding and letters of credit to governmental entities totaling $4.1 million primarily related to development and maintenance obligations for various projects. The estimated cost of the remaining development work is $2.0 million. ALLETE Properties does not believe it is likely that any of these outstanding surety bonds or letters of credit will be drawn upon.

Community Development District Obligations. As of March 31, 2020, we owned 53 percent of the assessable land in the Town Center District (53 percent as of December 31, 2019). As of March 31, 2020, ownership levels, our annual assessments related to capital improvement and special assessment bonds for the ALLETE Properties project within the district is approximately $1.9 million. As we sell property at this project, the obligation to pay special assessments will pass to the new landowners. In accordance with accounting guidance, these bonds are not reflected as debt on our Consolidated Balance Sheet.

Legal Proceedings.

We are involved in litigation arising in the normal course of business. Also in the normal course of business, we are involved in tax, regulatory and other governmental audits, inspections, investigations and other proceedings that involve state and federal taxes, safety, and compliance with regulations, rate base and cost of service issues, among other things. We do not expect the outcome of these matters to have a material effect on our financial position, results of operations or cash flows.

(a) For each of the three months ended March 31, 2020, and 2019, the federal and state current tax expense was minimal due to NOLs which resulted from the bonus depreciation provisions of the Protecting Americans from Tax Hikes Act of 2015, the Tax Increase Prevention Act of 2014 and the American Taxpayer Relief Act of 2012. Federal and state NOLs are being carried forward to offset current and future taxable income.

(b) For each of the three months ended March 31, 2020, and 2019, the federal income tax benefit is primarily due to production tax credits.

(c) For the three months ended March 31, 2019, the state income tax expense is primarily related to the sale of U.S. Water Services.

The Company's tax provision for interim periods is determined using an estimate of its annual effective tax rate, adjusted for discrete items arising in that quarter. In each quarter, the Company updates its estimate of the annual effective tax rate and if the estimated annual effective tax rate changes, the Company would make a cumulative adjustment in that quarter.

In addition to historical information, the following discussion and other parts of this Form 10-Q contain forward-looking information that involves risks and uncertainties. Readers are cautioned that forward-looking statements should be read in conjunction with our disclosures in this Form 10-Q, including Part II, Item 1A Risk Factors, and our 2019 Form 10-K under the headings: “Forward-Looking Statements” located on page 6 and “Risk Factors” located in Part I, Item 1A, beginning on page 21 of our 2019 Form 10-K. The risks and uncertainties described in this Form 10-Q and our 2019 Form 10-K are not the only risks facing our Company. Additional risks and uncertainties that we are not presently aware of, or that we currently consider immaterial, may also affect our business operations. Our business, financial condition or results of operations could suffer if the risks are realized.

Our financial position, results of operations and cash flows were not materially impacted during the three months ended March 31, 2020, by the ongoing COVID-19 pandemic; however, the trends and results for the first three months of 2020 may not be indicative of results that may be expected for the year ended December 31, 2020 due to uncertainty regarding the extent and duration of the COVID-19 pandemic. This pandemic has resulted in widespread impacts on the global economy and on our employees, customers, contractors, and suppliers. There is considerable uncertainty regarding the extent to which COVID-19 will spread and the extent and duration of measures to try to contain the virus, such as travel bans and restrictions, quarantines, shelter-in-place orders (including those in effect in areas our businesses operate), and business and government shutdowns. Additional disclosures in this Form 10-Q regarding the impacts of the ongoing COVID-19 pandemic are located in Outlook – Regulated Operations – Industrial Customers and Prospective Additional Load, Liquidity and Capital Resources – Liquidity Position and Part II, Item 1A. Risk Factors.

Regulated Operations includes our regulated utilities, Minnesota Power and SWL&P, as well as our investment in ATC, a Wisconsin-based regulated utility that owns and maintains electric transmission assets in portions of Wisconsin, Michigan, Minnesota and Illinois. Minnesota Power provides regulated utility electric service in northeastern Minnesota to approximately 145,000 retail customers. Minnesota Power also has 15 non-affiliated municipal customers in Minnesota. SWL&P is a Wisconsin utility and a wholesale customer of Minnesota Power. SWL&P provides regulated utility electric, natural gas and water service in northwestern Wisconsin to approximately 15,000 electric customers, 13,000 natural gas customers and 10,000 water customers. Our regulated utility operations include retail and wholesale activities under the jurisdiction of state and federal regulatory authorities. (See Note 2. Regulatory Matters.)

ALLETE Clean Energy focuses on developing, acquiring, and operating clean and renewable energy projects.

CONDITION AND RESULTS OF OPERATIONS (Continued)

ALLETE is incorporated under the laws of Minnesota. Our corporate headquarters are in Duluth, Minnesota. Statistical information is presented as of March 31, 2020, unless otherwise indicated. All subsidiaries are wholly-owned unless otherwise specifically indicated. References in this report to “we,” “us” and “our” are to ALLETE and its subsidiaries, collectively.

Financial Overview

The following net income discussion summarizes a comparison of the three months ended March 31, 2020, to the three months ended March 31, 2019. The trends and results for the first three months of 2020 may not be indicative of full year results for 2020 due to uncertainty regarding the extent and duration of the COVID-19 pandemic. (See Overview.)

Net income attributable to ALLETE for the three months ended March 31, 2020, was $66.3 million, or $1.28 per diluted share, compared to $70.5 million, or $1.37 per diluted share, for the same period in 2019. Net income in 2019 included a gain on the sale of U.S. Water Services of $9.9 million after-tax, or $0.19 per share, and U.S. Water Services results of operations amounted to a loss of $1.1 million after-tax, or $0.02 per share, in the first quarter. The full year gain on sale of U.S. Water Services in 2019 was $13.2 million after-tax, or $0.26 per share.

Regulated Operations net income attributable to ALLETE was $57.5 million for the three months ended March 31, 2020, compared to $51.5 million for the same period in 2019. Net income at Minnesota Power was higher than 2019 primarily due to the implementation of interim rates on January 1, 2020, increased cost recovery rider revenue, the timing of fuel adjustment clause recoveries in 2019 with the adoption of a new fuel adjustment clause methodology for Minnesota utilities beginning in 2020 (see Note 2. Regulatory Matters), and the timing of income taxes. These increases were partially offset by higher expenses, and lower kWh sales to residential, commercial and municipal customers in 2020. Net income at SWL&P was lower than 2019 primarily due to fewer gas and kWh sales to commercial and residential customers resulting from warmer weather in 2020 compared to 2019. Our after-tax equity earnings in ATC were similar to 2019.

ALLETE Clean Energy net income attributable to ALLETE was $11.7 million for the three months ended March 31, 2020, compared to $5.8 million for the same period in 2019. Net income in 2020 included $2.3 million of additional production tax credits generated compared to 2019, higher revenue resulting from higher wind resources and availability, and earnings from the Glen Ullin wind energy facility which commenced operations in December 2019. Net income in 2020 also included additional income tax benefit recorded in 2020 as GAAP requires the recognition of income taxes at the estimated annual effective tax rate. These increases were partially offset by higher depreciation expense.

U.S. Water Services net loss attributable to ALLETE was $1.1 million for three months ended March 31, 2019. ALLETE completed the sale of U.S. Water Services in the first quarter of 2019.

Corporate and Other net loss attributable to ALLETE was $2.9 million for the three months ended March 31, 2020, compared to net income of $14.3 million for the same period in 2019. Net income in 2019 included a gain on the sale of U.S. Water Services of $9.9 million after-tax. Net income in 2020 included lower earnings from marketable equity securities held in benefit trusts. Net income in 2020 also included additional income tax expense recorded in 2020 as GAAP requires the recognition of income taxes at the estimated annual effective tax rate.

Operating Revenue – Utility decreased $16.9 million from 2019 primarily due to lower fuel adjustment clause recoveries, revenue from kWh sales and conservation improvement program recoveries, partially offset by the implementation of interim rates on January 1, 2020, and increased cost recovery rider revenue.

Fuel adjustment clause revenue decreased $12.2 million due to lower fuel and purchased power costs attributable to retail and municipal customers, partially offset by the timing of fuel adjustment clause recoveries in 2019. Beginning in 2020, Minnesota utilities adopted a new fuel adjustment clause methodology. (See Note 2. Regulatory Matters.)

Revenue from kWh sales decreased $9.0 million from 2019 reflecting lower sales to residential, commercial and municipal customers. Sales to residential and commercial customers decreased from 2019 primarily due to warmer weather in 2020. Sales to municipal customers decreased from 2019 as a result of the expiration of a contract with a municipal customer in June 2019. Sales to industrial customers increased primarily due to additional sales to Silver Bay Power, which ceased self-generation in the third quarter of 2019.

Revenue from electric sales to taconite customers accounted for 26 percent of consolidated operating revenue in 2020 (22 percent in 2019). Revenue from electric sales to paper, pulp and secondary wood product customers accounted for 5 percent of consolidated operating revenue in 2020 (5 percent in 2019). Revenue from electric sales to pipelines and other industrial customers accounted for 7 percent of consolidated operating revenue in 2020 (7 percent in 2019).

Conservation improvement program recoveries decreased $2.1 million from 2019 primarily due to a decrease in related expenditures. (See Operating Expenses - Operating and Maintenance.)

Regulated Operations (Continued)

Interim retail rates for Minnesota Power, subject to refund, were approved by the MPUC and became effective January 1, 2020, resulting in revenue of $9.0 million. (See Note 2. Regulatory Matters.)

Cost recovery rider revenue increased $2.3 million primarily due to higher expenditures related to the construction of the GNTL.

Operating Expenses decreased $18.1 million, or 8 percent, from 2019.

Fuel, Purchased Power and Gas – Utility expense decreased $20.8 million, or 19 percent, from 2019 primarily due to lower purchased power prices and fuel costs. Fuel and purchased power expense related to our retail and municipal customers is recovered through the fuel adjustment clause.

Operating and Maintenance expense increased $1.6 million, or 3 percent, from 2019 primarily due to higher contract and professional service expenses and materials purchased for generation facilities, partially offset by a $2.1 million decrease in conservation improvement program expenses.

Depreciation and Amortization expense increased $1.9 million, or 5 percent, from 2019 primarily due to additional property, plant and equipment in service.

Taxes Other than Income Taxes decreased $1.0 million, or 8 percent, from 2019 primarily due to lower property tax expenses resulting from lower estimated taxable market values.

Income Tax Benefit increased $5.2 million from 2019 primarily due to higher production tax credits. We expect our annual effective tax rate in 2020 to be a higher income tax benefit than in 2019 primarily due to lower pre-tax income.

Net Loss Attributable to ALLETE was $1.1 million for the three months ended March 31, 2019. ALLETE completed the sale of U.S. Water Services in the first quarter of 2019.

Corporate and Other

Operating Revenue increased $2.1 million, or 9 percent, from 2019 primarily due to higher revenue at BNI Energy, which operates under cost-plus fixed fee contracts, as a result of higher expenses and more tons sold in 2020 compared to 2019.

Net Loss Attributable to ALLETE was $2.9 million in 2020 compared to net income $14.3 million in 2019. Net income in 2019 included a gain on the sale of U.S. Water Services of $9.9 million after-tax. Net income in 2020 included lower earnings from marketable equity securities held in benefit trusts. Net income in 2020 also included additional income tax expense recorded in 2020 as GAAP requires the recognition of income taxes at the estimated annual effective tax rate. Net income at BNI Energy was $0.7 million in 2020 compared to $1.9 million in 2019, reflecting lower earnings from marketable equity securities held in benefit trusts in 2020. The net loss at ALLETE Properties was $0.5 million in 2020 compared to a net loss of $0.6 million in 2019.

COMPARISON OF THE THREE MONTHS ENDED MARCH 31, 2020 AND 2019 (Continued)

Income Taxes – Consolidated

For the three months ended March 31, 2020, the effective tax rate was a benefit of 27.2 percent (expense of 4.0 percent for the three months ended March 31, 2019). The effective tax rate for 2020 was a higher benefit primarily due to 2019 including a higher tax rate on and higher pre-tax income resulting from the gain on the sale of U.S. Water Services in 2019.

We expect our annual effective tax rate in 2020 to be a higher benefit as compared to 2019 primarily due to higher production tax credits generated by ALLETE Clean Energy in 2020 and lower pre-tax income as 2019 reflected the gain on sale of U.S. Water Services. The effective rate deviated from the combined statutory rate of approximately 28 percent primarily due to production tax credits. (See Note 8. Income Tax Expense.)

CRITICAL ACCOUNTING POLICIES

Certain accounting measurements under GAAP involve management’s judgment about subjective factors and estimates, the effects of which are inherently uncertain. Accounting measurements that we believe are most critical to our reported results of operations and financial condition include: regulatory accounting, pension and postretirement health and life actuarial assumptions, impairment of long-lived assets, and taxation. These policies are reviewed with the Audit Committee of our Board of Directors on a regular basis and summarized in Part II, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations of our 2019 Form 10-K.

OUTLOOK

For additional information see our 2019 Form 10-K.

ALLETE is an energy company committed to earning a financial return that rewards our shareholders, allows for reinvestment in our businesses and sustains growth. The Company has long-term objectives of achieving average annual earnings per share growth of 5 percent to 7 percent, and providing a dividend payout competitive with our industry. Regulated Operations is projected to have average annual earnings growth of 4 percent to 5 percent over the long-term. ALLETE Clean Energy and our Corporate and Other businesses are projected to have average annual earnings growth of at least 15 percent over the long-term. Our annual earnings per share is expected to be negatively impacted in the short-term by the ongoing COVID-19 pandemic and related disruptions; however, the Company expects it will be able to maintain its stated financial objectives for average annual earnings per share growth over the long-term (next five years). (See Part II, Item 1A. Risk Factors.)

ALLETE is predominately a regulated utility through Minnesota Power, SWL&P and an investment in ATC. ALLETE’s strategy is to remain predominately a regulated utility while investing in ALLETE Clean Energy and our Corporate and Other businesses to complement its regulated businesses, balance exposure to the utility’s industrial customers and provide potential long-term earnings growth. ALLETE expects net income from Regulated Operations to be approximately 80 percent of total consolidated net income in 2020. Over the next several years, the contribution of ALLETE Clean Energy and our Corporate and Other businesses to net income is expected to increase as ALLETE grows these operations. ALLETE expects its businesses to provide regulated, contracted or recurring revenues, and to support sustained growth in net income and cash flow.

Regulated Operations. Minnesota Power’s long-term strategy is to be the leading electric energy provider in northeastern Minnesota by providing safe, reliable and cost-competitive electric energy, while complying with environmental permit conditions and renewable energy requirements. Keeping the cost of energy production competitive enables Minnesota Power to effectively compete in the wholesale power markets and minimizes retail rate increases to help maintain customer viability. As part of maintaining cost competitiveness, Minnesota Power intends to reduce its exposure to possible future carbon and GHG legislation by reshaping its generation portfolio, over time, to reduce its reliance on coal. (See EnergyForward.) We will monitor and review proposed environmental regulations and may challenge those that add considerable cost with limited environmental benefit. Minnesota Power will continue to pursue customer growth opportunities and cost recovery rider approvals for transmission, renewable and environmental investments, as well as work with regulators to earn a fair rate of return.

Regulatory Matters. Entities within our Regulated Operations segment are under the jurisdiction of the MPUC, FERC, PSCW and NDPSC. See Note 2. Regulatory Matters for discussion of regulatory matters within these jurisdictions.

2020 Minnesota General Rate Case. On November 1, 2019, Minnesota Power filed a retail rate increase request with the MPUC seeking an average increase of approximately 10.6 percent for retail customers. The rate filing seeks a return on equity of 10.05 percent and a 53.81 percent equity ratio. On an annualized basis, the requested final rate increase would generate approximately $66 million in additional revenue. In orders dated December 23, 2019, the MPUC accepted the filing as complete and authorized an annual interim rate increase of $36.1 million that began January 1, 2020. We cannot predict the level of final rates that may be authorized by the MPUC.

On April 23, 2020, Minnesota Power filed a request with the MPUC that proposes a resolution for Minnesota Power’s 2020 general rate case. Key components of our proposal include removing the current power marketing margin credit in base rates and reflecting actual power marketing margins in the fuel adjustment clause effective May 1, 2020; refunding to customers interim rates collected through April 2020 of approximately $12 million ($9 million as of March 31, 2020,); increasing ongoing customer rates 4.1 percent compared to the 5.8 percent increase reflected in current interim rates; and a provision that Minnesota Power would not file another rate case until at least March 1, 2021, unless certain events occur. Minnesota Power would withdraw its general rate case upon approval of this filing and proposed resolution by the MPUC. At a hearing on April 30, 2020, the MPUC approved lowering current interim rates to 4.1 percent effective May 1, 2020, as requested by Minnesota Power in this filing. A final decision on Minnesota Power’s full proposal in this filing is expected in June 2020. At this time, we are unable to predict whether the MPUC will ultimately approve this filing and proposed resolution, and thus, as of March 31, 2020, we have not recorded reserves for interim rates.

2018 Wisconsin General Rate Case. SWL&P’s current retail rates are based on a December 2018 PSCW order that allows for a return on equity of 10.4 percent and a 55.0 percent equity ratio. The PSCW has ordered SWL&P to file a general rate case in 2020.

Industrial Customers and Prospective Additional Load.

Industrial Customers. Electric power is one of several key inputs in the taconite mining, paper, pulp and secondary wood products, pipeline and other industries. Approximately 54 percent of our regulated utility kWh sales in the three months ended March 31, 2020, were made to our industrial customers (51 percent in the three months ended March 31, 2019). These customers and their markets have been impacted by the ongoing COVID-19 pandemic. (See Part II, Item 1A. Risk Factors.)

The ongoing COVID-19 pandemic and related federal and state government responses has led to a disruption of economic activity, and could result in an extended disruption of economic activity. This disruption is expected to result in reduced sales and revenue from industrial customers. The states of Minnesota and Wisconsin issued stay-at-home or shelter-in-place orders in March 2020 that remain in effect, and many non-essential commercial and industrial customers are operating at reduced levels or are temporarily closed or idled. In addition, Cliffs temporarily idled its Northshore Mining operation, Hibbing Taconite temporarily idled production and USS Corporation indefinitely idled its Keetac plant as well as announced a temporary partial shutdown at its Minntac plant, each of which are served by Minnesota Power. (See Northshore Mining, Hibbing Taconite and USS Corporation.) The current disruption of economic activity or an extended disruption of economic activity may lead to additional adverse impacts on our taconite and paper, pulp and secondary wood products, pipeline and other industrial customers’ operations including further reduced production or the temporary idling or indefinite shutdown of other facilities, which would result in lower sales and revenue from these customers.

Taconite. Minnesota Power’s taconite customers are capable of producing up to approximately 41 million tons of taconite pellets annually. Taconite pellets produced in Minnesota are primarily shipped to North American steel making facilities that are part of the integrated steel industry. Steel produced from these North American facilities is used primarily in the manufacture of automobiles, appliances, pipe and tube products for the gas and oil industry, and in the construction industry. Historically, less than 10 percent of Minnesota taconite production has been exported outside of North America.

OUTLOOK (Continued)

Industrial Customers and Prospective Additional Load (Continued)

There has been a general historical correlation between U.S. steel production and Minnesota taconite production. The American Iron and Steel Institute, an association of North American steel producers, reported that U.S. raw steel production operated at approximately 81 percent of capacity during the first three months of 2020 compared to 82 percent in the first three months of 2019; however, the American Iron and Steel Institute also reported that U.S. raw steel production in the last week of April 2020 had decreased to approximately 51 percent of capacity. The World Steel Association, an association of steel producers, national and regional steel industry associations, and steel research institutes representing approximately 85 percent of world steel production, projected in October 2019 that U.S. steel consumption in 2020 will increase by approximately one percent compared to 2019; however, this projection was made before the COVID-19 pandemic and the World Steel Association announced in April 2020 that it had decided to postpone its U.S. steel consumption update projection typically released in April each year due to continuing disruption caused by the COVID-19 pandemic.

Minnesota Power’s taconite customers may experience annual variations in production levels due to such factors as economic conditions, short-term demand changes or maintenance outages. We estimate that a one million ton change in Minnesota Power’s taconite customers’ production would impact our annual earnings per share by approximately $0.04, net of expected power marketing sales at current prices. Changes in wholesale electric prices or customer contractual demand nominations could impact this estimate. Minnesota Power proactively sells power in the wholesale power markets that is temporarily not required by industrial customers to optimize the value of its generating facilities. Long-term reductions in taconite production or a permanent shut down of a taconite customer may lead Minnesota Power to file a general rate case to recover lost revenue.

Northshore Mining. Cliffs is currently constructing a hot briquetted iron production plant in Toledo, Ohio, and had begun shipping direct reduced-grade pellets form Northshore Mining to the Toledo plant in anticipation of the planned start of operations in mid-2020. On March 19, 2020, following guidelines from the office of the Governor of Ohio regarding the COVID-19 pandemic, Cliffs temporarily shut down construction activities at its hot briquetted iron project site. On April 13, 2020, Cliffs announced that based on current market conditions, it will be temporarily idling production at two of its iron ore mining operations, Northshore Mining in Minnesota and Tilden Mine in Michigan. Cliffs idled production at Northshore Mining in April 2020 and plans to restart the facility by August 2020, subject to business conditions. Northshore Mining has the capability to produce approximately 6 million tons annually. Minnesota Power has a PSA through 2031 with Silver Bay Power, which provides the majority of the electric service requirements for Northshore Mining. (See Silver Bay Power.)

Silver Bay Power. In 2016, Minnesota Power and Silver Bay Power entered into a PSA through 2031. Silver Bay Power supplies approximately 90 MW of load to Northshore Mining, an affiliate of Silver Bay Power, which had previously been served predominately through self-generation by Silver Bay Power. Starting in 2016, Minnesota Power supplied Silver Bay Power with at least 50 MW of energy and Silver Bay Power had the option to purchase additional energy from Minnesota Power as it transitioned away from self-generation. In the third quarter of 2019, Silver Bay Power ceased self-generation and Minnesota Power began supplying the full energy requirements for Silver Bay Power.

USS Corporation. In April 2020, USS Corporation stated it would indefinitely idle its Keetac facility in Keewatin, Minnesota, in response to the sudden and dramatic decline in business conditions resulting from the COVID-19 pandemic. In addition, on May 1, 2020, USS Corporation announced reduced production expected temporarily at its Minntac Plant in Mountain Iron, Minnesota until July 2020. USS Corporation has the capability to produce approximately 20 million tons annually at its Minntac and Keetac plants.

Hibbing Taconite. On April 20, 2020, ArcelorMittal announced that Hibbing Taconite in Hibbing, Minnesota, would idle production until July 2020 due to the COVID-19 pandemic. Hibbing Taconite has the capability to produce approximately 8 million tons annually.

Paper, Pulp and Secondary Wood Products. The North American paper and pulp industry faces declining demand due to the impact of electronic substitution for print and changing customer needs. As a result, certain paper and pulp customers have reduced their existing operations in recent years and have pursued or are pursuing product changes in response to the declining demand. In addition, the ongoing COVID-19 pandemic and related federal and state government responses could adversely impact these customers’ operations and result in lower operating levels than expected or the temporary idling or indefinite shutdown of facilities.

Boise. On April 1, 2020, Packaging Corporation of America announced an idling of both paper machines and the sheet-converting operation at its Jackson Mill in Alabama for the months of May and June 2020. As part of that announcement, Packaging Corporation of America also stated that the company's Boise paper mill in International Falls, Minnesota, which is a customer of Minnesota Power, will continue to operate at capacity during this period.

Pipeline and Other Industries.

Husky Energy. In April 2018, a fire at Husky Energy’s refinery in Superior, Wisconsin, disrupted operations at the facility. Under normal operating conditions, SWL&P provides approximately 14 MW of average monthly demand to Husky Energy in addition to water service. On September 30, 2019, Husky Energy announced that it had received the required permit approvals to begin reconstruction. On April 20, 2020, Husky Energy announced that rebuild construction at the refinery had been suspended due to the COVID-19 pandemic. Husky Energy did not provide a timeline for when construction would resume. The facility remains at minimal operations.

Prospective Additional Load. Minnesota Power is pursuing new wholesale and retail loads in and around its service territory. Currently, several companies in northeastern Minnesota continue to progress in the development of natural resource-based projects that represent long-term growth potential and load diversity for Minnesota Power. We cannot predict the outcome of these projects.

PolyMet. PolyMet is planning to start a new copper-nickel and precious metal (non-ferrous) mining operation in northeastern Minnesota. In 2015, PolyMet announced the completion of the final EIS by state and federal agencies, which was subsequently published in the Federal Register and Minnesota Environmental Quality Board Monitor. The Minnesota Department of Natural Resources (DNR) and the U.S. Army Corps of Engineers have both issued final Records of Decision, finding the final EIS adequate.

In 2016, PolyMet submitted applications for water-related permits with the DNR and MPCA, an air quality permit with the MPCA, and a state permit to mine application with the DNR detailing its operational plans for the mine. In June 2018, the U.S. Forest Service and PolyMet closed on a land exchange, which resulted in PolyMet obtaining surface rights to land needed to develop its mining operation. In November 2018, the DNR issued PolyMet’s permit to mine and certain water-related permits. In December 2018, the MPCA issued PolyMet’s final state water and air quality permits. On March 21, 2019, the U.S. Army Corps of Engineers issued PolyMet’s final federal permit. PolyMet was issued all necessary permits to construct and operate its new mining operation; however, on January 13, 2020, the Minnesota Court of Appeals reversed the DNR’s decisions granting PolyMet’s permit to mine and dam-safety permits, and remanded them back to the DNR to hold a contested-case hearing. On February 11, 2020, PolyMet announced it had filed a petition for further review with the Minnesota Supreme Court seeking to overturn the Minnesota Court of Appeals decision, which was accepted for review by the Minnesota Supreme Court on March 25, 2020. Minnesota Power could supply between 45 MW and 50 MW of load under a 10‑year power supply contract with PolyMet that would begin upon start-up of operations.

EnergyForward. Minnesota Power is executing EnergyForward, a strategic plan for assuring reliability, protecting affordability and further improving environmental performance. The plan includes completed and planned investments in wind, solar, natural gas and hydroelectric power, construction of additional transmission capacity, the installation of emissions control technology and the idling of certain coal-fired generating facilities.

Nemadji Trail Energy Center. In 2017, Minnesota Power submitted a resource package to the MPUC which included requesting approval of a 250 MW natural gas capacity dedication agreement. The natural gas capacity dedication agreement was subject to MPUC approval of the construction of NTEC, a 525 MW to 550 MW combined-cycle natural gas‑fired generating facility which will be jointly owned by Dairyland Power Cooperative and a subsidiary of ALLETE. Minnesota Power would purchase approximately 50 percent of the facility's output starting in 2025. In an order dated January 24, 2019, the MPUC approved Minnesota Power’s request for approval of the NTEC natural gas capacity dedication agreement. Separately, the MPUC required a baseload retirement evaluation in Minnesota Power’s next IRP filing analyzing its existing fleet, including potential early retirement scenarios of Boswell Units 3 and 4, as well as a securitization plan. On December 23, 2019, the Minnesota Court of Appeals reversed and remanded the MPUC’s decision to approve certain affiliated-interest agreements. The MPUC was ordered to determine whether NTEC may have the potential for significant environmental effects and, if so, to prepare an environmental assessment worksheet before reassessing the agreements. On January 22, 2020, Minnesota Power filed a petition for further review with the Minnesota Supreme Court requesting that it review and overturn the Minnesota Court of Appeals decision, which petition was accepted for review by the Minnesota Supreme Court on March 18, 2020. On January 8, 2019, an application for a certificate of public convenience and necessity for NTEC was submitted to the PSCW, which was approved by the PSCW at a hearing on January 16, 2020. Construction of NTEC is subject to obtaining additional permits from local, state and federal authorities. The total project cost is estimated to be approximately $700 million, of which ALLETE’s portion is expected to be approximately $350 million. ALLETE’s portion of NTEC project costs incurred through March 31, 2020, is approximately $13 million.

Integrated Resource Plan. In a 2016 order, the MPUC approved Minnesota Power’s 2015 IRP with modifications. The order accepted Minnesota Power’s plans for the economic idling of Taconite Harbor Units 1 and 2 and the ceasing of coal-fired operations at Taconite Harbor in 2020, directed Minnesota Power to retire Boswell Units 1 and 2 no later than 2022, required an analysis of generation and demand response alternatives to be filed with a natural gas resource proposal, and required Minnesota Power to conduct requests for proposal for additional wind, solar and demand response resource additions. Minnesota Power retired Boswell Units 1 and 2 in the fourth quarter of 2018. Minnesota Power’s next IRP filing is due October 1, 2020. (See Note 2. Regulatory Matters.)

Renewable Energy. Minnesota Power’s 2015 IRP includes an update on its plans and progress in meeting the Minnesota renewable energy milestones through 2025. Minnesota Power continues to execute its renewable energy strategy and expects approximately 50 percent of its energy will be supplied by renewable energy sources by 2021.

Solar Energy. Minnesota Power’s solar energy supply consists of Camp Ripley, a 10 MW solar energy facility at the Camp Ripley Minnesota Army National Guard base and training facility near Little Falls, Minnesota, and a community solar garden project in northeastern Minnesota, which is comprised of a 1 MW solar array owned and operated by a third party with the output purchased by Minnesota Power and a 40 kW solar array that is owned and operated by Minnesota Power.

Minnesota Power has approval for current cost recovery of investments and expenditures related to compliance with the Minnesota Solar Energy Standard. Currently, there is no approved customer billing rate for solar costs.

Wind Energy. Minnesota Power’s wind energy facilities consist of Bison (497 MW) located in North Dakota, and Taconite Ridge (25 MW) located in northeastern Minnesota. Minnesota Power also has two long-term wind energy PPAs with an affiliate of NextEra Energy, Inc. to purchase the output from Oliver Wind I (50 MW) and Oliver Wind II (48 MW) located in North Dakota.

Minnesota Power uses the 465-mile, 250-kV DC transmission line that runs from Center, North Dakota, to Duluth, Minnesota, to transport wind energy from North Dakota while gradually phasing out coal-based electricity delivered to its system over this transmission line from Square Butte’s lignite coal-fired generating unit. Minnesota Power is currently pursuing a modernization and capacity upgrade of its DC transmission system to continue providing reliable operations and additional system capabilities.

Minnesota Power has an approved cost recovery rider for certain renewable investments and expenditures. The cost recovery rider allows Minnesota Power to charge retail customers on a current basis for the costs of certain renewable investments plus a return on the capital invested. Updated customer billing rates for the renewable cost recovery rider were provisionally approved by the MPUC in a November 2018 order.

Nobles 2 PPA. In the third quarter of 2018, Minnesota Power and Nobles 2 signed an amended long-term PPA that provides for Minnesota Power to purchase the energy and associated capacity from a 250 MW wind energy facility in southwestern Minnesota for a 20-year period beginning in 2020. The agreement provides for the purchase of output from the facility at fixed energy prices. There are no fixed capacity charges, and Minnesota Power will only pay for energy as it is delivered. This agreement is subject to construction of the wind energy facility. (See Note 3. Equity Investments.)

Manitoba Hydro. Minnesota Power has five long-term PPAs with Manitoba Hydro. The first PPA expires in May 2020. Under this agreement, Minnesota Power is purchasing 50 MW of capacity and the energy associated with that capacity. Both the capacity price and the energy price are adjusted annually by the change in a governmental inflationary index. Under the second PPA, Minnesota Power is purchasing surplus energy through April 2022. This energy-only agreement primarily consists of surplus hydro energy on Manitoba Hydro’s system that is delivered to Minnesota Power on a non-firm basis. The pricing is based on forward market prices. Under this agreement, Minnesota Power will purchase at least one million MWh of energy over the contract term.

The third PPA provides for Minnesota Power to purchase 250 MW of capacity and energy from Manitoba Hydro for 15 years beginning in 2020. The PPA is subject to the construction of the GNTL and MMTP. (See Note 6. Commitments, Guarantees and Contingencies.) The capacity price is adjusted annually until 2020 by the change in a governmental inflationary index. The energy price is based on a formula that includes an annual fixed price component adjusted for the change in a governmental inflationary index and a natural gas index, as well as market prices.

The fourth PPA provides for Minnesota Power to purchase up to 133 MW of energy from Manitoba Hydro for 20 years beginning in 2020. The pricing under this PPA is based on forward market prices. The PPA is subject to the construction of the GNTL and MMTP. (See Note 6. Commitments, Guarantees and Contingencies.)

OUTLOOK (Continued)

EnergyForward (Continued)

The fifth PPA provides for Minnesota Power to purchase 50 MW of capacity from Manitoba Hydro at fixed prices. The PPA began in June 2017 and expires in May 2020.

Transmission. We continue to make investments in transmission opportunities that strengthen or enhance the transmission grid or take advantage of our geographical location between sources of renewable energy and end users. These include the GNTL, investments to enhance our own transmission facilities, investments in other transmission assets (individually or in combination with others) and our investment in ATC.

Great Northern Transmission Line. As a condition of the 250-MW long-term PPA entered into with Manitoba Hydro, construction of additional transmission capacity is required. As a result, Minnesota Power is constructing the GNTL, an approximately 220‑mile 500-kV transmission line between Manitoba and Minnesota’s Iron Range that was proposed by Minnesota Power and Manitoba Hydro in order to strengthen the electric grid, enhance regional reliability and promote a greater exchange of sustainable energy.

In a 2016 order, the MPUC approved the route permit for the GNTL, and in 2016, the U.S. Department of Energy issued a presidential permit to cross the U.S.-Canadian border, which was the final major regulatory approval needed before construction in the U.S. could begin. Construction activities commenced in the first quarter of 2017, and Minnesota Power expects the GNTL to be in-service by mid-2020. The total project cost in the U.S., including substation work, is estimated to be approximately $700 million, of which Minnesota Power’s portion is expected to be approximately $325 million; the difference will be recovered from a subsidiary of Manitoba Hydro as non-shareholder contributions to capital. Total project costs of $647.7 million have been incurred through March 31, 2020, of which $344.6 million has been recovered from a subsidiary of Manitoba Hydro. (See Note 6. Commitments, Guarantees and Contingencies.)

Investment in ATC. Our wholly-owned subsidiary, ALLETE Transmission Holdings, owns approximately 8 percent of ATC, a Wisconsin-based utility that owns and maintains electric transmission assets in portions of Wisconsin, Michigan, Minnesota and Illinois. We account for our investment in ATC under the equity method of accounting. As of March 31, 2020, our equity investment in ATC was $142.3 million ($141.6 million as of December 31, 2019). In the three months ended March 31, 2020, we invested $0.4 million in ATC, and on April 30, 2020, we invested an additional $0.8 million. We expect to make additional investments of $1.6 million in 2020.

ATC’s authorized return on equity is 9.88 percent, or 10.38 percent including an incentive adder for participation in a regional transmission organization based on a November 2019 FERC order. In this order, the FERC reduced the base return on equity for regional transmission organizations as recommended by an administrative law judge with refunds ordered for prior periods. Multiple parties to the complaint have filed requests for rehearing of the FERC order.

ATC’s 10-year transmission assessment, which covers the years 2019 through 2028, identifies a need for between $2.9 billion and $3.6 billion in transmission system investments. These investments by ATC, if undertaken, are expected to be funded through a combination of internally generated cash, debt and investor contributions. As opportunities arise, we plan to make additional investments in ATC through general capital calls based upon our pro rata ownership interest in ATC.

ALLETE Clean Energy.

ALLETE Clean Energy focuses on developing, acquiring, and operating clean and renewable energy projects. ALLETE Clean Energy currently owns and operates, in six states, approximately 740 MW of nameplate capacity wind energy generation that is contracted under PSAs of various durations. In addition, ALLETE Clean Energy currently has approximately 300 MW of wind energy facilities under construction that it will own and operate with long-term PSAs in place. ALLETE Clean Energy also engages in the development of wind energy facilities to operate under long-term PSAs or for sale to others upon completion.

ALLETE Clean Energy believes the market for renewable energy in North America is robust, driven by several factors including environmental regulation, tax incentives, societal expectations and continual technology advances. State renewable portfolio standards and state or federal regulations to limit GHG emissions are examples of environmental regulation or public policy that we believe will drive renewable energy development.

ALLETE Clean Energy’s strategy includes the safe, reliable, optimal and profitable operation of its existing facilities. This includes a strong safety culture, the continuous pursuit of operational efficiencies at existing facilities and cost controls. ALLETE Clean Energy generally acquires facilities in liquid power markets and its strategy includes the exploration of PSA extensions upon expiration of existing contracts and production tax credit requalification of existing facilities.

ALLETE, Inc. First Quarter 2020 Form 10-Q

OUTLOOK (Continued)

ALLETE Clean Energy (Continued)

ALLETE Clean Energy will pursue growth through acquisitions or project development. ALLETE Clean Energy is targeting acquisitions of existing facilities up to 200 MW each, which have long-term PSAs in place for the facilities’ output. At this time, ALLETE Clean Energy expects acquisitions or development of new facilities will be primarily wind or solar facilities in North America. ALLETE Clean Energy is also targeting the development of new facilities up to 200 MW each, which will have long‑term PSAs in place for the output or may be sold upon completion.

Federal production tax credit qualification is important to the economics of project development, and ALLETE Clean Energy has invested in equipment to meet production tax credit safe harbor provisions which provides an opportunity to seek development of up to approximately 1,000 MW of production tax credit qualified wind projects through 2022. ALLETE Clean Energy will also invest approximately $80 million through 2020 for production tax credit requalification of up to approximately 500 WTGs at its Storm Lake I, Storm Lake II, Lake Benton and Condon wind energy facilities. We anticipate annual production tax credits relating to these projects of approximately $20 million in 2020, $17 million to $22 million annually in 2021 through 2027 and decreasing thereafter through 2030. Disruptions in our supply chains or a lack of available financing resulting from the ongoing COVID-19 pandemic, if they occur, could jeopardize our ability to complete certain capital projects in time to qualify them for production tax credits. (See Part II, Item 1A. Risk Factors.)

In 2018, ALLETE Clean Energy announced that it will build, own and operate the South Peak wind project, an 80 MW wind energy facility in Montana, pursuant to a 15-year PSA with NorthWestern Corporation; construction was completed and tax equity funding was received in the second quarter of 2020.

In May 2019, ALLETE Clean Energy acquired the Diamond Spring wind project in Oklahoma from Apex Clean Energy. ALLETE Clean Energy will build, own and operate the approximately 300 MW wind energy facility. The Diamond Spring wind project is fully contracted to sell wind power under long-term power sales agreements. Construction is expected to be completed in late 2020.

On March 10, 2020, ALLETE Clean Energy acquired the rights to the Caddo wind project in Oklahoma from Apex Clean Energy for approximately $8 million with additional payments required to be made at defined milestones. The full development of this approximately 300 MW wind project would involve the sale of energy to corporate customers under long-term power sales agreements.

ALLETE Clean Energy manages risk by having a diverse portfolio of assets, which includes PSA expiration, technology and geographic diversity. The current operating portfolio of approximately 740 MW is subject to typical variations in seasonal wind with higher wind resources typically available in the winter months. The majority of its planned maintenance leverages this seasonality and is performed during lower wind periods. The current mix of PSA expiration and geographic location for existing facilities is as follows:

Wind Energy Facility	Location	Capacity MW	PSA MW	PSA Expiration
Armenia Mountain	East	101	100%	2024
Chanarambie/Viking	Midwest	98
PSA 1 (a)			12%	2023
PSA 2			88%	2023
Condon	West	50	100%	2022
Glen Ullin	West	106	100%	2039
Lake Benton	Midwest	104	100%	2028
South Peak	West	80	100%	2035
Storm Lake I	Midwest	108	100%	2027
Storm Lake II	Midwest	77
PSA 1			90%	2022
PSA 2			10%	2032
Other	Midwest	17	100%	2028

(a) The PSA expiration assumes the exercise of all renewal options that ALLETE Clean Energy has the sole right to exercise.

Corporate and Other.

BNI Energy. BNI Energy anticipates selling 4.6 million tons of lignite coal in 2020 (4.1 million tons were sold in 2019) and has sold 1.2 million tons for the three months ended March 31, 2020 (1.1 million tons were sold for the three months ended March 31, 2019). BNI Energy operates under cost-plus fixed fee agreements extending through December 31, 2037.

Investment in Nobles 2. Our wholly-owned subsidiary, ALLETE South Wind, owns 49 percent of Nobles 2, the entity that will own and operate a 250 MW wind energy facility in southwestern Minnesota pursuant to a 20-year PPA with Minnesota Power. The wind energy facility will be built in Nobles County, Minnesota, and is expected to be completed in late 2020, with an estimated total project cost of approximately $350 million to $400 million. In the fourth quarter of 2019, we entered into a tax equity funding agreement to finance approximately $116 million of the project costs. We account for our investment in Nobles 2 under the equity method of accounting. As of March 31, 2020, our equity investment in Nobles 2 was $83.4 million ($56.0 million at December 31, 2019). In the three months ended March 31, 2020, we invested $27.4 million in Nobles 2, and in April 2020 we invested an additional $21.7 million. We expect to make approximately $65 million in additional investments in 2020.

ALLETE Properties. ALLETE Properties represents our legacy Florida real estate investment. ALLETE Properties’ major project in Florida is Town Center at Palm Coast, with approximately 800 acres of land available for sale. In addition to this project, ALLETE Properties has approximately 600 acres of other land available for sale. Market conditions can impact land sales and could result in our inability to cover our cost basis and operating expenses including fixed carrying costs such as community development district assessments and property taxes.

Our strategy incorporates the possibility of a bulk sale of the entire ALLETE Properties portfolio. Proceeds from a bulk sale would be strategically deployed to support growth initiatives at our Regulated Operations and ALLETE Clean Energy. ALLETE Properties also continues to pursue sales of individual parcels over time and will continue to maintain key entitlements and infrastructure.

Income Taxes.

ALLETE’s aggregate federal and multi-state statutory tax rate is approximately 28 percent for 2020. ALLETE also has tax credits and other tax adjustments that reduce the combined statutory rate to the effective tax rate. These tax credits and adjustments historically have included items such as investment tax credits, production tax credits, AFUDC‑Equity, depletion, as well as other items. The annual effective rate can also be impacted by such items as changes in income before income taxes, state and federal tax law changes that become effective during the year, business combinations, tax planning initiatives and resolution of prior years’ tax matters. We expect our effective tax rate to be a benefit of approximately 25 percent to 30 percent for 2020 primarily due to federal production tax credits as a result of wind energy generation. We also expect that our effective tax rate will be lower than the combined statutory rate over the next 10 years due to production tax credits attributable to our wind energy generation.

LIQUIDITY AND CAPITAL RESOURCES

Liquidity Position. ALLETE is well-positioned to meet the Company’s liquidity needs; however, the Company is monitoring capital markets and other financing sources in light of the ongoing COVID-19 pandemic. (See Part II, Item 1A. Risk Factors.) A disruption in capital markets could lead to increased borrowing costs or adversely impact our ability to access capital markets or other financing sources. If we are not able to access capital on acceptable terms in sufficient amounts and when needed, or at all, the ability to maintain our businesses or to implement our business plans would be adversely affected.

As of March 31, 2020, we had cash and cash equivalents of $67.0 million, $340.5 million in available consolidated lines of credit, 2.9 million original issue shares of common stock available for issuance through a distribution agreement with Lampert Capital Markets, $90 million available for borrowing under a $200 million term loan entered into in January 2020 and a debt-to-capital ratio of 42 percent. (See Working Capital.)

In addition, ALLETE has agreed to sell $140 million of the Company's first mortgage bonds to be issued on or before August 3, 2020, and on April 8, 2020, ALLETE entered into a $115 million term loan agreement with $95 million borrowed upon execution. (See Note 5. Short-Term and Long-Term Debt.) On April 29, 2020, we received approximately $70 million in cash from a third-party investor as part of a tax equity financing for ALLETE Clean Energy’s South Peak wind energy facility. The Company also has approximately $116 million in commitments from tax equity partners for our investment in Nobles 2, and the Company is actively seeking tax equity funding for ALLETE Clean Energy’s Diamond Spring wind project.

		$4,104.3	100		$3,958.2	100

Cash Flows. Selected information from the Consolidated Statement of Cash Flows is as follows:

For the Three Months Ended March 31,	2020			2019
Millions
Cash, Cash Equivalents and Restricted Cash at Beginning of Period		$92.5			$79.0
Cash Flows from (used for)
Operating Activities	88.8			79.1
Investing Activities	(182.5		)	185.1
Financing Activities	80.1			22.0
Change in Cash, Cash Equivalents and Restricted Cash	(13.6		)	286.2
Cash, Cash Equivalents and Restricted Cash at End of Period		$78.9			$365.2

Operating Activities. Cash from operating activities was slightly higher in 2020 compared to 2019 as cash from operating activities in 2019 included higher non-cash earnings resulting from the gain on sale of U.S. Water Services, the refund of Minnesota Power’s provision for tax reform, and the impact of U.S. Water Services prior to its sale. Cash from operating activities in 2020 reflected lower collections of accounts receivable due to timing and lower cash collected from current cost recovery riders.

Investing Activities. Cash used for investing activities was higher in 2020 compared to 2019. Cash from investing activities in 2019 included proceeds received from the sale of U.S. Water Services. Cash used for investing activities in 2020 included higher additions to property, plant and equipment and additional payments for equity method investments compared to 2019.

Financing Activities. Cash from financing activities was higher in 2020 compared to 2019 primarily due to lower repayments of long-term debt in 2020.

Working Capital. Additional working capital, if and when needed, generally is provided by consolidated bank lines of credit and the issuance of securities, including long-term debt, common stock and commercial paper. As of March 31, 2020, we had consolidated bank lines of credit aggregating $407.0 million ($407.0 million as of December 31, 2019), the majority of which expire in January 2024. We had $66.3 million outstanding in standby letters of credit and $0.2 million outstanding draws under our lines of credit as of March 31, 2020 ($62.0 million in standby letters of credit and no outstanding draws as of December 31, 2019). In addition, as of March 31, 2020, we had 3.6 million original issue shares of our common stock available for issuance through Invest Direct, our direct stock purchase and dividend reinvestment plan, and 2.9 million original issue shares of common stock available for issuance through a distribution agreement with Lampert Capital Markets. The amount and timing of future sales of our securities will depend upon market conditions and our specific needs. In July 2019, we filed Registration Statement No. 333-232905, pursuant to which the remaining shares will continue to be offered for sale, from time to time.

Securities. During the three months ended March 31, 2020, we issued 0.1 million shares of common stock through Invest Direct, the Employee Stock Purchase Plan, and the Retirement Savings and Stock Ownership Plan, resulting in net proceeds of $3.3 million (0.1 million shares were issued for the three months ended March 31, 2019, resulting in net proceeds of $0.8 million). These shares of common stock were registered under Registration Statement Nos. 333-231030, 333-211075, 333-183051 and 333-162890.

Financial Covenants. See Note 5. Short-Term and Long-Term Debt for information regarding our financial covenants.

Pension and Other Postretirement Benefit Plans. Management considers various factors when making funding decisions, such as regulatory requirements, actuarially determined minimum contribution requirements and contributions required to avoid benefit restrictions for the defined benefit pension plans.

LIQUIDITY AND CAPITAL RESOURCES (Continued)

Off-Balance Sheet Arrangements. Off-balance sheet arrangements are summarized in our 2019 Form 10-K, with additional disclosure in Note 6. Commitments, Guarantees and Contingencies.

Credit Ratings. Access to reasonably priced capital markets is dependent in part on credit and ratings. Our securities have been rated by S&P Global Ratings and by Moody’s. Rating agencies use both quantitative and qualitative measures in determining a company’s credit rating. These measures include business risk, liquidity risk, competitive position, capital mix, financial condition, predictability of cash flows, management strength and future direction. Some of the quantitative measures can be analyzed through a few key financial ratios, while the qualitative ones are more subjective. Our current credit ratings are listed in the following table:

Credit Ratings	S&P Global Ratings	Moody’s
Issuer Credit Rating	BBB	Baa1
Commercial Paper	A-2	P-2
First Mortgage Bonds	(a)	A2

(a) Not rated by S&P Global Ratings.

On April 22, 2020, S&P Global Ratings downgraded ALLETE’s long-term issuer credit rating to BBB stable from BBB+ outlook negative and affirmed its short-term rating at A-2. S&P Global Ratings noted the impacts of debt coverage ratios going forward along with the lack of a revenue decoupling mechanism at Minnesota Power combined with the large commercial and industrial presence in its service territory as its rationale for the downgrade.

The disclosure of these credit ratings is not a recommendation to buy, sell or hold our securities. Ratings are subject to revision or withdrawal at any time by the assigning rating organization. Each rating should be evaluated independently of any other rating.

Capital Requirements. Our capital expenditures for 2020 are expected to be approximately $535 million; however, the Company is evaluating its planned capital expenditures and may make adjustments to mitigate impacts of the ongoing COVID-19 pandemic, if appropriate. At this time, we do not have an update to the amount of capital expenditures expected in 2020 due to uncertainty regarding the extent and duration of the COVID-19 pandemic. For the three months ended March 31, 2020, capital expenditures totaled $161.8 million ($85.1 million for the three months ended March 31, 2019). The expenditures were primarily made in the Regulated Operations and ALLETE Clean Energy segments.

OTHER

Environmental Matters.

Our businesses are subject to regulation of environmental matters by various federal, state and local authorities. A number of regulatory changes to the Clean Air Act, the Clean Water Act and various waste management requirements have been promulgated by both the EPA and state authorities over the past several years. Minnesota Power’s facilities are subject to additional requirements under many of these regulations. Minnesota Power is reshaping its generation portfolio, over time, to reduce its reliance on coal, has installed cost-effective emission control technology, and advocates for sound science and policy during rulemaking implementation. (See Note 6. Commitments, Guarantees and Contingencies.)

Employees.

As of March 31, 2020, ALLETE had 1,352 employees, of which 1,328 were full-time.

Minnesota Power and SWL&P have an aggregate of 471 employees who are members of International Brotherhood of Electrical Workers (IBEW) Local 31. The current labor agreements with IBEW Local 31 expire on April 30, 2023, for Minnesota Power and February 1, 2021, for SWL&P.

BNI Energy has 181 employees, of which 135 are subject to a labor agreement with IBEW Local 1593. The current labor agreement with IBEW Local 1593 expires on March 31, 2023.

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

SECURITIES INVESTMENTS

Available-for-Sale Securities. As of March 31, 2020, our available-for-sale securities portfolio consisted primarily of securities held in other postretirement plans to fund employee benefits.

COMMODITY PRICE RISK

Our regulated utility operations incur costs for power and fuel (primarily coal and related transportation) in Minnesota, and power and natural gas purchased for resale in our regulated service territory in Wisconsin. Minnesota Power’s exposure to price risk for these commodities is significantly mitigated by the current ratemaking process and regulatory framework, which allows recovery of fuel costs in excess of those included in base rates or distribution of savings in fuel costs to ratepayers. SWL&P’s exposure to price risk for natural gas is significantly mitigated by the current ratemaking process and regulatory framework, which allows the commodity cost to be passed through to customers. We seek to prudently manage our customers’ exposure to price risk by entering into contracts of various durations and terms for the purchase of power and coal and related transportation costs (Minnesota Power), and natural gas (SWL&P).

POWER MARKETING

Minnesota Power’s power marketing activities consist of: (1) purchasing energy in the wholesale market to serve its regulated service territory when energy requirements exceed generation output; and (2) selling excess available energy and purchased power. From time to time, Minnesota Power may have excess energy that is temporarily not required by retail and municipal customers in our regulated service territory. Minnesota Power actively sells any excess energy to the wholesale market to optimize the value of its generating facilities.

We are exposed to credit risk primarily through our power marketing activities. We use credit policies to manage credit risk, which includes utilizing an established credit approval process and monitoring counterparty limits.

INTEREST RATE RISK

We are exposed to risks resulting from changes in interest rates as a result of our issuance of variable rate debt. We manage our interest rate risk by varying the issuance and maturity dates of our fixed rate debt, limiting the amount of variable rate debt, and continually monitoring the effects of market changes in interest rates. We may also enter into derivative financial instruments, such as interest rate swaps, to mitigate interest rate exposure. Interest rates on variable rate long-term debt are reset on a periodic basis reflecting prevailing market conditions. Based on the variable rate debt outstanding as of March 31, 2020, an increase of 100 basis points in interest rates would impact the amount of pre-tax interest expense by $2.6 million. This amount was determined by considering the impact of a hypothetical 100 basis point increase to the average variable interest rate on the variable rate debt outstanding as of March 31, 2020.

ITEM 4.  CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures. As of March 31, 2020, evaluations were performed, under the supervision and with the participation of management, including our principal executive officer and principal financial officer, on the effectiveness of the design and operation of ALLETE’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934 (Exchange Act)). Based upon those evaluations, our principal executive officer and principal financial officer have concluded that such disclosure controls and procedures are effective to provide assurance that information required to be disclosed in ALLETE’s reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer, to allow timely decisions regarding required disclosure.

Such information is incorporated herein by reference.

ITEM 1A.  RISK FACTORS

Our 2019 Form 10-K includes a detailed discussion of our risk factors. The information presented below updates, and should be read in conjunction with, the risk factors disclosed in Part I, Item 1A. Risk Factors of our 2019 Form 10-K.

We could be materially adversely affected by the ongoing COVID-19 pandemic for which we are unable to predict the ultimate impact as the extent and duration of the COVID-19 pandemic is uncertain.

The ongoing COVID-19 pandemic has resulted in widespread impacts on the global economy and on our employees, customers, contractors, and suppliers. There is considerable uncertainty regarding the extent to which COVID-19 will spread and the extent and duration of measures to try to contain the virus, such as travel bans and restrictions, quarantines, shelter-in-place orders (including those in effect in areas our businesses operate), and business and government shutdowns. We are responding to the COVID-19 pandemic by taking steps to mitigate the potential risks to us posed by its spread and have implemented our company-wide business continuity plans in response to the pandemic. These plans guide our emergency response, business continuity, and the precautionary measures we are taking on behalf of employees and the public. We have taken additional precautions for our employees who work in the field and for employees who continue to work in our facilities, and we have implemented work from home policies where appropriate. We continue to implement physical and cyber-security measures to ensure that our systems remain functional in order to both serve our operational needs with a remote workforce and keep them running to ensure uninterrupted service to our customers.

The ongoing COVID-19 pandemic and related federal and state government responses has led to a disruption of economic activity, and could result in an extended disruption of economic activity. This disruption has resulted and is expected to continue to result in reduced sales and revenue from commercial, municipal and industrial customers as well as an increase in uncollectible accounts from residential and commercial customers. The states of Minnesota and Wisconsin issued stay-at-home or shelter-in-place orders in March 2020 that remain in effect, and many non-essential commercial and industrial customers are operating at reduced levels or are temporarily closed or idled. In addition, as a result of the COVID-19 pandemic, Cliffs temporarily idled its Northshore Mining operation, Hibbing Taconite temporarily idled production and USS Corporation indefinitely idled its Keetac plant as well as announced a temporary partial shutdown at its Minntac plant, each of which are served by Minnesota Power. (See Outlook – Regulated Operations – Industrial Customers and Prospective Additional Load.) The current disruption of economic activity or an extended disruption of economic activity may lead to additional adverse impacts on our taconite mining, paper, pulp and secondary wood products, and pipeline customers’ operations including further reduced production or the temporary idling or indefinite shutdown of other facilities, which would result in lower sales and revenue from these customers. In Minnesota Power’s service territory, we have also voluntarily and as requested by state regulators extended Minnesota’s cold weather rule as well as temporarily suspended disconnections for non-payment and waved late payment charges for residential and small business customers. In SWL&P’s service territory, we have implemented state regulator requested customer service actions to further limit service disconnections and late payment charges for residential, commercial and industrial customers.

ITEM 1A.  RISK FACTORS (Continued)

We could be materially adversely affected by the ongoing COVID-19 pandemic for which we are unable to predict the ultimate impact as the extent and duration of the COVID-19 pandemic is uncertain (Continued)

The Company is monitoring the capital markets and has access to liquidity to enable us to operate our businesses and fund capital projects; however, a disruption in capital markets could lead to increased borrowing costs or adversely impact our ability to access capital markets or other financing sources. If we are not able to access capital on acceptable terms in sufficient amounts and when needed, or at all, the ability to maintain our businesses or to implement our business plans would be adversely affected. In addition, the performance of capital markets impacts the values of the assets that are held in trust to satisfy future obligations under our pension and other postretirement benefit plans. A decline in the market value of these assets would increase the funding requirements under our benefit plans and future costs recognized for the benefit plans if the asset market values do not recover. The Company is also monitoring supply chains for key materials, supplies and services for our operations and large capital projects. We have received notices of force majeure from certain suppliers and the pandemic could result in a disruption to our supply chains which could adversely impact our operations and capital projects; however, there has been limited impact on our supply chains as to the availability of materials, supplies and services to date. In addition, disruptions in our supply chains or a lack of available financing could jeopardize our ability to complete certain capital projects in time to qualify them for production tax credits.

We will continue to monitor developments affecting our workforce, operations and customers, and we will take additional precautions that we determine are necessary in order to mitigate the impacts of the COVID-19 pandemic. Despite our efforts to manage these impacts to the Company, their ultimate impact also depends on factors beyond our control, including the duration and severity of this pandemic as well as governmental and third-party actions taken to contain its spread and mitigate its public health effects. As a result, we cannot predict the ultimate impact of the COVID-19 pandemic and whether it will have a material impact on our liquidity, financial position, results of operations and cash flows.

Any change in the Alternate Base Rate due to a change in the Prime Rate, the Federal Funds Effective Rate, or the LIBO Rate shall be effective from the effective date of such change.

Amounts prepaid or repaid in respect of Effective Date Term Loans may not be reborrowed.

Amounts prepaid or repaid in respect of Delayed Draw Term Loans may not be reborrowed.

Section 2.2.Loans and Borrowings.

(a)Each Loan shall be made as part of a Borrowing consisting of Loans of the same Class and Type made by the Lenders ratably in accordance with their respective Commitments of the applicable Class. The failure of any Lender to make any Loan required to be made by it shall not relieve any other Lender of its obligations hereunder, provided that the Commitments of the Lenders are several, and no Lender shall be responsible for any other Lender’s failure to make any Loan as required.

(b)Subject to Section 3.4, each Borrowing shall be comprised entirely of ABR Loans or Eurodollar Loans, as applicable, in each case as the Borrower may request in accordance herewith. Each Lender at its option may make any Eurodollar Loan (and any ABR Loan, the interest on which is determined pursuant to clause (d) of the definition of Alternate Base Rate) by causing any domestic or foreign branch or Affiliate of such Lender to make such Loan, provided that any exercise of such option shall not affect the obligation of the Borrower to repay such Loan in accordance with the terms of this Agreement.

(c)At the commencement of each Interest Period for any Eurodollar Borrowing, such Borrowing shall be in an aggregate amount that is $5,000,000 or a higher integral multiple of $1,000,000. At the time that each ABR Borrowing is made, such Borrowing shall be in an aggregate amount that is $5,000,000 or a higher integral multiple of $1,000,000. Borrowings of more than one Type and Class may be outstanding at the same time, provided that there shall not at any time be more than a total of ten Eurodollar Borrowings outstanding.

22

Exhibit 4

(d)Notwithstanding any other provision of this Agreement, the Borrower shall not be entitled to request, or to elect to convert or continue, any Borrowing if the Interest Period requested with respect thereto would end after the Maturity Date.

Section 2.3.Requests for Borrowings.

(a)To request a Borrowing, the Borrower shall deliver a Credit Request to the Administrative Agent (2) in the case of a Eurodollar Borrowing, not later than 12:30 p.m. three Business Days before the date of the proposed Borrowing or (2) in the case of an ABR Borrowing, not later than 12:30 p.m. on the date of the proposed Borrowing. Each such Credit Request shall be irrevocable (except as otherwise provided in Section 3.4) and shall specify the following information in compliance with Section 2.2:

(i)the Class of Borrowing and the aggregate amount of the requested Borrowing;

(ii)the date of such Borrowing, which shall be a Business Day;

(iii)whether such Borrowing is to be an ABR Borrowing or a Eurodollar Borrowing;

(iv)in the case of a Eurodollar Borrowing, the initial Interest Period to be applicable thereto, which shall be a period contemplated by the definition of the term “Interest Period”; and

(v)the location and number of the Borrower’s account to which funds are to be disbursed, which shall comply with the requirements of Section 2.4.

(b)If no election as to the Type of Borrowing is specified, then the requested Borrowing shall be an ABR Borrowing. If no Interest Period is specified with respect to any requested Eurodollar Borrowing, then the Borrower shall be deemed to have selected an Interest Period of one month’s duration. Promptly following receipt of a Credit Request in accordance with this Section, the Administrative Agent shall advise each applicable Lender of the details thereof and of the amount of such Lender’s Loan to be made as part of the requested Borrowing.

Section 2.4.Funding of Borrowings.

(a)Each Lender shall make each Loan to be made by it hereunder on the proposed date thereof by wire transfer of immediately available funds by 2:00 p.m. to the account of the Administrative Agent most recently designated by it for such purpose by notice to the Lenders. Subject to Section 5.2, the Administrative Agent will make such Loans available to the Borrower by promptly crediting or otherwise transferring the amounts so received, in like funds, to an account of the Borrower designated by the Borrower in the applicable Credit Request.

(b)Unless the Administrative Agent shall have received notice from a Lender prior to the proposed date of any Borrowing that such Lender will not make available to the Administrative Agent such Lender’s share of such Borrowing, the Administrative Agent may assume that such Lender has made such share available on such date in accordance with Section 2.4(a) and may, in reliance upon such assumption, make available to the Borrower a corresponding amount. In such event, if a Lender

23

Exhibit 4

has not in fact made its share of the applicable Borrowing available to the Administrative Agent, then the applicable Lender and the Borrower severally agree to pay to the Administrative Agent forthwith on demand such corresponding amount with interest thereon, for each day from and including the date such amount is made available to the Borrower to but excluding the date of payment to the Administrative Agent, at the interest rate that would be otherwise applicable to such Borrowing. Any payment by the Borrower, however, shall be without prejudice to its rights against the applicable Lender. If such Lender pays such amount to the Administrative Agent, then such amount shall constitute such Lender’s Loan.

Section 2.5.Termination and Reduction of Commitments.

(a)The Effective Date Commitments shall automatically and permanently terminate on the Effective Date upon the funding of the Effective Date Term Loans.

(b)The Borrower may at any time terminate, or from time to time reduce, the Delayed Draw Commitments, provided that (i) each reduction of such Commitments shall be in the amount of $5,000,000 or a higher integral multiple of $1,000,000 and (ii) unless previously terminated, the Delayed Draw Commitments shall automatically and permanently terminate on the earlier of (x) the Maturity Date and (y) date of the funding of the Delayed Draw Term Loans upon the funding thereof.

(c)The Borrower shall notify the Administrative Agent of any election to terminate or reduce the Delayed Draw Commitments under paragraph (b) of this Section at least three Business Days prior to the effective date of such termination or reduction, specifying such election and the effective date thereof. Promptly following receipt of any notice, the Administrative Agent shall advise the Delayed Draw Lenders of the contents thereof. Each notice delivered by the Borrower pursuant to this Section shall be irrevocable, provided that a notice of termination of the Delayed Draw Commitments delivered by the Borrower may state that such notice is conditioned upon the effectiveness of other credit facilities, in which case such notice may be revoked by the Borrower (by notice to the Administrative Agent on or prior to the specified effective date) if such condition is not satisfied. Each reduction, and any termination, of the Delayed Draw Commitments shall be permanent and each reduction of the Delayed Draw Commitments shall be made ratably among the Delayed Draw Lenders in accordance with their respective Delayed Draw Commitments.

Section 2.6.Repayment of Loans; Evidence of Debt.

(a)The Borrower hereby unconditionally promises to pay to the Administrative Agent (i) for the account of each Effective Date Lender the then unpaid principal amount of each Effective Date Term Loan on the Maturity Date, (ii) for the account of each Delayed Draw Lender the then unpaid principal amount of each Delayed Draw Term Loan on the Maturity Date and (iii) for the account of each Incremental Lender the then unpaid principal amount of each Incremental Term Loan on the Maturity Date.

(b)Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing the debt of the Borrower to such Lender resulting from each Loan made by such Lender, including the amounts of principal and interest payable and paid to such Lender from time to time hereunder.

24

Exhibit 4

payable from the Borrower to each Lender hereunder and (2) the amount of any sum received by the Administrative Agent hereunder for the account of the Lenders and each Lender’s share thereof.

(d)The entries made in the accounts maintained pursuant to paragraph (b) or (c) of this Section shall be prima facie evidence of the existence and amounts of the obligations recorded therein, provided that the failure of any Lender or the Administrative Agent to maintain such accounts or any error therein shall not in any manner affect the obligation of the Borrower to repay the Loans in accordance with the terms of this Agreement.

(e)Any Lender may request that its Loans be evidenced by a Note. In such event, the Borrower shall prepare, execute and deliver to such Lender a Note payable to the order of such Lender. Thereafter, the Loans evidenced by such Note and interest thereon shall at all times (including after any assignment pursuant to Section 10.4) be represented by a Note payable to the order of the payee named therein or any Eligible Assignee pursuant to Section 10.4, except to the extent that any such Lender or Eligible Assignee subsequently returns any such Note for cancellation and requests that such Loans once again be evidenced as described in paragraphs (b) and (c) above.

Section 2.7.Prepayment of Loans.

(a)Voluntary Prepayments. The Borrower shall have the right at any time and from time to time to prepay any Borrowing in whole or in part, subject to the requirements of this Section.

(b)Notice of Prepayment; Application of Prepayments. The Borrower shall notify the Administrative Agent by telephone (confirmed by facsimile) of any prepayment hereunder, (i) in the case of a prepayment of a Eurodollar Borrowing, not later than 11:30 a.m. three Business Days before the date of prepayment or (ii) in the case of prepayment of an ABR Borrowing, not later than 11:30 a.m. on the date of the prepayment. Each such notice shall be irrevocable and shall specify the prepayment date and the principal amount of each Borrowing or portion thereof to be prepaid, provided that, if a notice of prepayment is given in connection with a conditional notice of termination of the Commitments as contemplated by Section 2.5, then such notice of prepayment may be revoked if such notice of termination is revoked in accordance with Section 2.5. Promptly following receipt of any such notice relating to a Borrowing, the Administrative Agent shall advise the Lenders of the contents thereof. Each partial prepayment of any Borrowing shall be in an integral multiple of $1,000,000 and not less than $5,000,000 (or, if the outstanding principal balance of the applicable Borrowing is less than such minimum amount, then such lesser outstanding principal balance. Each prepayment of a Borrowing shall be applied ratably to the Loans included in the prepaid Borrowing. Prepayments shall be accompanied by accrued interest to the extent required by Section 3.1 and, if applicable, shall be subject to the provisions of Section 3.6.

Section 2.8.Payments Generally; Pro Rata Treatment; Sharing of Set‑offs.

(a)The Borrower shall make each payment required to be made by it hereunder or under any other Loan Document (whether of principal of Loans, interest or fees, or of amounts payable under Sections 3.5, 3.6, 3.7 or 10.3, or otherwise) prior to 1:00 p.m. on the date when due, in immediately available funds, without set‑off or counterclaim. Any amounts received after such time on any date may, in the discretion of the Administrative Agent, be deemed to have been received on the next succeeding Business Day for purposes of calculating interest thereon. All such payments shall be made to the Administrative Agent at its office at 10 S. Dearborn, Chicago, Illinois, or such other office as to which

25

Exhibit 4

the Administrative Agent may notify the other parties hereto, except that payments pursuant to Sections 3.3(c), 3.5, 3.6, 3.7 and 10.3 shall be made directly to the Persons entitled thereto. The Administrative Agent shall distribute any such payments received by it for the account of any other Person to the appropriate recipient promptly following receipt thereof. If any payment hereunder shall be due on a day that is not a Business Day, the date for payment shall be extended to the next succeeding Business Day, and, in the case of any payment accruing interest, interest thereon shall be payable for the period of such extension. All payments hereunder shall be made in dollars.

(b)Each Borrowing, each payment or prepayment of principal of any Borrowing, each payment of interest on the Loans, each payment of fees, each reduction of the Delayed Draw Commitments and each conversion of any Borrowing to or continuation of any Borrowing as a Borrowing of any Type shall be allocated pro rata among the Lenders in accordance with their respective applicable Commitments (or, if such Commitments shall have expired or been terminated, in accordance with the respective principal amounts of their outstanding Loans). All payments (including prepayments) shall be applied to pay the Loans of the Lenders pro rata in accordance with their Total Percentages. Each Lender agrees that in computing such Lender’s portion of any Borrowing to be made hereunder, the Administrative Agent may, in its discretion, round each Lender’s percentage of such Borrowing to the next higher or lower whole dollar amount. If at any time insufficient funds are received by and available to the Administrative Agent to pay fully all amounts of principal of Loans, interest, fees and commissions then due hereunder, such funds shall be applied (2) first, towards payment of interest, fees and commissions then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of interest, fees and commissions then due to such parties and (2) second, towards payment of principal of Loans then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of principal of Loans then due to such parties.

(c)If any Lender shall, by exercising any right of set‑off or counterclaim or otherwise, obtain payment in respect of any principal of, or interest on, any of its Loans resulting in such Lender receiving payment of a greater proportion of the aggregate amount of its Loans and accrued interest thereon than the proportion received by any other Lender, then the Lender receiving such greater proportion shall purchase (for cash at face value) participations in the Loans of other Lenders to the extent necessary so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of, and accrued interest on, their respective Loans, provided that (2) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest, and (2) the provisions of this paragraph shall not be construed to apply to any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement or any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans to any assignee or participant, other than to the Borrower or any Subsidiary or Affiliate thereof (as to which the provisions of this paragraph shall apply). The Borrower consents to the foregoing and agrees, to the extent it may effectively do so under applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against the Borrower rights of set‑off and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of the Borrower in the amount of such participation.

(d)Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Administrative Agent for the account of the applicable Credit Parties hereunder that the Borrower will not make such payment, the Administrative Agent may assume that the Borrower has made such payment on such date in accordance herewith and may, in

26

Exhibit 4

reliance upon such assumption, distribute to such Credit Parties the amount due. In such event, if the Borrower has not in fact made such payment, then each such Credit Party severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Credit Party with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to the Administrative Agent, at the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation.

(e)If any Credit Party shall fail to make any payment required to be made by it pursuant to Section 2.4(b) or 2.8(d), then the Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), (i) apply any amounts thereafter received by the Administrative Agent for the account of such Credit Party to satisfy such Credit Party’s obligations under such Sections until all such unsatisfied obligations are fully paid and (ii) hold any such amounts in a segregated account as cash collateral for, and application to, any future funding obligations of such Lender under such Sections; in the case of each of (i) and (ii) above, in any order as determined by the Administrative Agent in its discretion.

Section 2.9.Defaulting Lenders. Notwithstanding any provision of this Agreement to the contrary, if any Lender becomes a Defaulting Lender, then the following provisions shall apply for so long as such Lender is a Defaulting Lender:

(a)Fees pursuant to Section 3.3(a) shall cease to accrue on the unfunded portion of the Delayed Draw Commitment of such Defaulting Lender.

(b)The Commitments and Loans of such Defaulting Lender shall not be included in determining whether all Lenders or the Required Lenders have voted or taken or may take any action hereunder (including any consent to any amendment, modification or waiver pursuant to Section 10.2); provided that (i) any waiver, amendment or modification requiring the consent of all Lenders or each affected Lender which affects such Defaulting Lender differently than other affected Lenders shall require the consent of such Defaulting Lender and (ii) any amendment or modification that increases, or extends the maturity of, such Defaulting Lender’s Commitment or reduces the principal amount of, or rate of interest on, any Loan made by such Defaulting Lender, shall require the consent of such Defaulting Lender.

27

Exhibit 4

unreasonably withheld or delayed) of the Administrative Agent. Notwithstanding anything herein to the contrary, no Lender shall have any obligation to agree to provide an Incremental Term Loan pursuant to this Section 2.10, and any election to do so shall be in the sole discretion of such Lender.

(c)Incremental Effective Date. The Administrative Agent and the Borrower shall determine the effective date for each Incremental Term Loan pursuant to this Section 2.10 (an “Incremental Effective Date”) and, if applicable, the final allocation of such Incremental Term Loan among the Persons providing it, which date shall be a Business Day at least 10 Business Days after delivery of the request pursuant to Section 2.10(a) (unless otherwise approved by the Administrative Agent) and at least 30 days before the Maturity Date.

(d)Conditions to Effectiveness. Notwithstanding the foregoing, no Incremental Term Loans shall be effective with respect to any Incremental Lender unless:

(i)no Default has occurred and is continuing on the Incremental Effective Date and after giving effect to such Incremental Term Loan;

(ii)the representations and warranties in this Agreement are true and correct in all material respects on and as of the Incremental Effective Date and after giving effect to such increase, as though made on and as of such date (or, if any such representation or warranty is expressly stated to have been made as of a specific date, as of such specific date);

(iii)the Administrative Agent has received the documents required pursuant to Section 2.10(e); and

(iv)the Administrative Agent has received such legal opinions and other documents reasonably requested by the Administrative Agent in connection therewith.

Effective as of the applicable Incremental Effective Date, subject to the terms and conditions set forth in this Section 2.10, each Incremental Term Loan shall be a Loan hereunder, and each Incremental Lender providing such Incremental Term Loan shall be, and have all the rights of, a Lender, for all purposes of this Agreement.

(c)Accrued interest on each Loan shall be payable in arrears on each Interest Payment Date for such Loan, provided that (3) interest accrued pursuant to paragraph (b) of this Section shall be payable on demand, (3) in the event of any repayment or prepayment of any Loan, accrued interest on the principal amount repaid or prepaid shall be payable on the date of such repayment or prepayment, and (3) in the event of any conversion of any Eurodollar Loan prior to the end of the current Interest Period therefor, accrued interest on such Loan shall be payable on the effective date of such conversion.

(d)All interest hereunder shall be computed on the basis of a year of 360 days, except that interest computed by reference to the Alternate Base Rate at times when the Alternate Base Rate is based on the Prime Rate shall be computed on the basis of a year of 365 days (or 366 days in a leap year), and in each case shall be payable for the actual number of days elapsed (including the first day but excluding the last day). The applicable Alternate Base Rate, Adjusted LIBO Rate or LIBO Rate shall be determined by the Administrative Agent, and such determination shall be conclusive absent clearly demonstrable error. The Administrative Agent shall, as soon as practicable, notify the Borrower and the Lenders of the effective date and the amount of each change in the Prime Rate or ABR, but any failure to so notify shall not in any manner affect the obligation of the Borrower to pay interest on the Loans in the amounts and on the dates required.

Section 3.2.Interest Elections Relating to Borrowings.

(a)Each Borrowing initially shall be of the Type specified in the applicable Credit Request and, in the case of a Eurodollar Borrowing, shall have an initial Interest Period as specified in such Credit Request. Thereafter, the Borrower may elect to convert such Borrowing to a different Type or to continue such Borrowing and, in the case of a Eurodollar Borrowing, may elect Interest Periods therefor, all as provided in this Section. The Borrower may elect different options with respect to different

29

Exhibit 4

portions of the affected Borrowing, in which case each such portion shall be allocated ratably among the Lenders holding the Loans comprising such Borrowing, and the Loans comprising each such portion shall be considered a separate Borrowing.

(b)To make an election pursuant to this Section, the Borrower shall deliver to the Administrative Agent a signed Interest Election Request in a form approved by the Administrative Agent by the time that a Credit Request would be required under Section 2.3 if the Borrower were requesting a Borrowing of the Type resulting from such election to be made on the effective date of such election.

(c)Each such Interest Election Request shall be irrevocable (except as otherwise provided in Section 3.4) and shall specify the following information:

(i)the Borrowing to which such Interest Election Request applies and, if different options are being elected with respect to different portions thereof, the portions thereof to be allocated to each resulting Borrowing (in which case the information to be specified pursuant to clauses (iii) and (iv) of this paragraph shall be specified for each resulting Borrowing);

(ii)the effective date of the election made pursuant to such Interest Election Request, which shall be a Business Day;

(iii)whether the resulting Borrowing is to be an ABR Borrowing or a Eurodollar Borrowing; and

(iv)if the resulting Borrowing is a Eurodollar Borrowing, the Interest Period to be applicable thereto after giving effect to such election, which shall be a period contemplated by the definition of the term “Interest Period”.

If any such Interest Election Request requests a Eurodollar Borrowing but does not specify an Interest Period, then the Borrower shall be deemed to have selected an Interest Period of one month’s duration.

(d)Promptly following receipt of an Interest Election Request, the Administrative Agent shall advise each Lender of the applicable Class of the details thereof and of such Lender’s portion of each resulting Borrowing.

(e)If the Borrower fails to deliver a timely Interest Election Request prior to the end of the Interest Period applicable thereto, then, unless such Borrowing is repaid as provided herein, at the end of such Interest Period, such Borrowing shall be converted to an ABR Borrowing. Notwithstanding any contrary provision hereof, if an Event of Default has occurred and is continuing and the Administrative Agent, at the request of the Required Lenders, so notifies the Borrower, then, so long as an Event of Default is continuing, (i) no outstanding Borrowing may be converted to or continued as a Eurodollar Borrowing and (ii) unless repaid, each Eurodollar Borrowing shall be converted to an ABR Borrowing at the end of the Interest Period applicable thereto.

Section 3.3.Fees.

(a)The Borrower agrees to pay to the Administrative Agent for the account of each Delayed Draw Lender, a ticking fee, which shall accrue at a rate per annum equal to .30% on the daily amount of the Delayed Draw Commitment of such Lender during the period from and including the date

30

Exhibit 4

on which this Agreement becomes effective pursuant to Section 10.6 to but excluding the date on which such Delayed Draw Commitment terminates. Accrued ticking fees shall be payable in arrears on the last day of March, June, September and December of each year, each date on which the Delayed Draw Commitments are permanently reduced and on the date on which the Delayed Draw Commitments terminate, commencing on the first such date to occur after the Effective Date, provided that all unpaid ticking fees shall be payable on the date on which the Delayed Draw Commitments terminate. All ticking fees shall be computed on the basis of a year of 360 days and shall be payable for the actual number of days elapsed (including the first day but excluding the last day).

(b)The Borrower agrees to pay to each Credit Party, for its own account, fees and other amounts payable in the amounts and at the times separately agreed upon in writing between the Borrower and such Credit Party.

(c)All fees and other amounts payable hereunder shall be paid on the dates due, in immediately available funds. Fees and other amounts paid shall not be refundable under any circumstances other than clearly demonstrable error.

Section 3.4.Availability of Types of Borrowings; Adequacy of Interest Rate.

(a)Notwithstanding anything to the contrary in this Agreement or any other Loan Document, if the Administrative Agent determines (which determination shall be conclusive absent manifest error), or the Required Lenders notify the Administrative Agent that the Required Lenders have determined, that:

(i)deposits of a type and maturity appropriate to match fund Eurodollar Borrowings are not available to such Lenders in the relevant market, or

(ii)the interest rate applicable to Eurodollar Borrowings for any requested Interest Period is not ascertainable or available (including, without limitation, because the applicable Reuters Screen (or on any successor or substitute page on such screen) is unavailable) or does not adequately and fairly reflect the cost of making or maintaining Eurodollar Borrowings,

then the Administrative Agent shall suspend the availability of Eurodollar Borrowings and require any affected Eurodollar Borrowings to be repaid or converted to ABR Borrowings,subject to the payment of any funding indemnification amounts required by Section 3.4.

(b)Notwithstanding the foregoing or anything to the contrary in this Agreement or any other Loan Document, if the Administrative Agent determines (which determination shall be conclusive absent manifest error), or the Required Lenders notify the Administrative Agent (with a copy to the Borrower) that the Required Lenders have determined, that any one or more of the following (each, a “Benchmark Transition Event”) has occurred:

(i)the circumstances set forth in Section 3.4(a)(ii) have arisen (including, without limitation, a public statement or publication of information by the regulatory supervisor for the administrator of the LIBO Rate described in clause (ii) of this Section 3.4(b) announcing that the LIBO Rate is no longer representative) and such circumstances are unlikely to be temporary,

31

Exhibit 4

(ii)ICE Benchmark Administration (or any Person that has taken over the administration of the LIBO Rate for deposits in Dollars that is acceptable to the Administrative Agent) discontinues its administration and publication of the LIBO Rate for deposits in Dollars,

(iii)a public statement or publication of information by or on behalf of the administrator of the LIBO Rate described in clause (ii) of this Section 3.4(b) announcing that such administrator has ceased or will cease as of a specific date to provide the LIBO Rate (permanently or indefinitely); provided that, at the time of such statement, there is no successor administrator that is acceptable to the Administrative Agent that will continue to provide the LIBO Rate after such specified date,

(iv)a public statement by the supervisor for the administrator of the LIBO Rate described in clause (ii) of this Section 3.4(b), the U.S. Federal Reserve System, an insolvency official with jurisdiction over such administrator for the LIBO Rate, a resolution authority with jurisdiction over such administrator for the LIBO Rate or a court or an entity with similar insolvency or resolution authority over such administrator for the LIBO Rate, which states that such administrator of the LIBO Rate has ceased or will cease as of a specific date to provide the LIBO Rate (permanently or indefinitely); provided that, at the time of such statement or publication, there is no successor administrator that is acceptable to the Administrative Agent that will continue to provide the LIBO Rate after such specified date; or

(v)syndicated credit facilities substantially similar to the credit facilities under this Agreement being executed at such time, or that include language substantially similar to that contained in this Section 3.4(b), are being executed or amended, as the case may be, to incorporate or adopt a new benchmark interest rate to replace the LIBO Rate for deposits in Dollars

then the Administrative Agent and the Borrower may amend this Agreement to replace the LIBO Rate with a Benchmark Replacement. Notwithstanding anything to the contrary in Section 10.2, any such amendment with respect to a Benchmark Transition Event (A) pursuant to any of clauses (i) through (iv) of this Section 3.4(b) will become effective without any further action or consent of any other party to this Agreement at 5:00 p.m. (New York City time) on the fifth Business Day after the Administrative Agent has posted such proposed amendment to all Lenders and the Borrower so long as the Administrative Agent has not received, by such time, written notice of objection to such amendment from Lenders comprising the Required Lenders or (B) pursuant to clause (v) of this Section 3.4(b), will become effective without any further action or consent of any other party to this Agreement on the date that Lenders comprising the Required Lenders have delivered to the Administrative Agent written notice that such Required Lenders accept such amendment; provided that, if the notice of a Benchmark Trigger Event pursuant to clause (v) has been provided by the Required Lenders and not the Administrative Agent and such notice specifies the Benchmark Replacement, then the Lenders comprising the Required Lenders shall be deemed to have accepted such amendment on the date such amendment has been posted by the Administrative Agent to all Lenders. No replacement of the LIBO Rate with a Benchmark Replacement pursuant to this Section 3.4(b) will occur prior to the date set forth in the applicable amendment.

32

Exhibit 4

In connection with the implementation of a Benchmark Replacement, the Administrative Agent will have the right to make Benchmark Replacement Conforming Changes from time to time and, notwithstanding anything to the contrary herein or in any other Loan Document, any amendments implementing such Benchmark Replacement Conforming Changes will become effective without any further action or consent of any other party to this Agreement.

The Administrative Agent will promptly notify the Borrower and the Lenders of (1) any occurrence of a Benchmark Transition Event (other than pursuant to clause (v) of this Section 3.4(b)), (2) the implementation of any Benchmark Replacement, (3) the effectiveness of any Benchmark Replacement Conforming Changes and (4) the commencement or conclusion of any Benchmark Unavailability Period. Any determination, decision or election that may be made by the Administrative Agent or Lenders pursuant to this Section 3.4(b), including any determination with respect to a tenor, rate or adjustment or of the occurrence or non-occurrence of an event, circumstance or date and any decision to take or refrain from taking any action, will be conclusive and binding absent manifest error and may be made in its or their sole discretion and without consent from any other party hereto, except, in each case, as expressly required pursuant to this Section 3.4(b).

(c)Upon notice to the Borrower by the Administrative Agent in accordance with Section 10.1 of the commencement of a Benchmark Unavailability Period and until a Benchmark Replacement is determined in accordance with this Section 3.4(b), (A) any request pursuant to Section 3.2 that requests the conversion of any Borrowing to, or continuation of any Borrowing as, a Eurodollar Borrowing may be revoked by the Borrower and if not revoked shall be ineffective and any such Borrowing shall be continued as or converted to, as the case may be, an ABR Borrowing, and (B) if any request pursuant to Section 2.3 requests a Eurodollar Borrowing, such request may be revoked by the Borrower and if not revoked such Borrowing shall be made as an ABR Borrowing. During any Benchmark Unavailability Period, the component of the Alternate Base Rate based upon the Eurodollar Rate will not be used in any determination of the Alternate Base Rate.

Section 3.5.Increased Costs; Illegality.

(a)If any Change in Law shall:

(i)impose, modify or deem applicable any reserve, special deposit, liquidity or similar requirement against assets of, deposits with or for the account of, or credit extended by, any Credit Party (except any such reserve requirement reflected in the Adjusted LIBO Rate);

(ii)subject any Recipient to any Taxes with respect to this Agreement or on its Loans, loan principal, Commitments, or other obligations, or its deposits, reserves, other liabilities or capital attributable thereto in respect thereof (other than (A) Indemnified Taxes and (B) Excluded Taxes); or

(iii)impose on any Credit Party or the London interbank market any other condition affecting this Agreement, any Eurodollar Loans made by such Credit Party or any participation therein;

and the result of any of the foregoing shall be to increase the cost to such Credit Party of making, continuing, converting or maintaining any Eurodollar Loan hereunder or to increase the cost to such Credit Party or

33

Exhibit 4

to reduce the amount of any sum received or receivable by such Credit Party hereunder (whether of principal, interest or otherwise), then the Borrower will pay to such Credit Party such additional amount or amounts as will compensate such Credit Party for such additional costs incurred or reduction suffered.

(b)If any Credit Party determines that any Change in Law regarding capital or liquidity requirements has or would have the effect of reducing the rate of return on such Credit Party’s capital or on the capital of such Credit Party’s holding company, if any, as a consequence of this Agreement or the Loans made by such Credit Party to a level below that which such Credit Party or such Credit Party’s holding company could have achieved but for such Change in Law (taking into consideration such Credit Party’s policies and the policies of such Credit Party’s holding company with respect to capital adequacy), then from time to time the Borrower will pay to such Credit Party such additional amount or amounts as will compensate such Credit Party or such Credit Party’s holding company for any such reduction suffered.

(c)A certificate of a Credit Party setting forth the amount or amounts necessary to compensate such Credit Party or its holding company, as applicable, as specified in paragraph (a) or (b) of this Section shall be delivered to the Borrower and shall be conclusive and binding upon all parties hereto absent manifest error. The Borrower shall pay such Credit Party the amount shown as due on any such certificate within 10 Business Days after receipt thereof.

(d)Failure or delay on the part of any Credit Party to demand compensation pursuant to this Section shall not constitute a waiver of such Credit Party’s right to demand such compensation; provided that the Borrower shall not be required to compensate a Credit Party pursuant to this Section for any increased costs or reductions incurred more than 180 days prior to the date that such Credit Party notifies the Borrower of the Change in Law giving rise to such increased costs or reductions and of such Credit Party’s intention to claim compensation therefor; and providedfurther that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the 180 day period referred to above shall be extended to include the period of retroactive effect thereof but not to exceed a period of 365 days.

(e)Notwithstanding any other provision of this Agreement, if any Change in Law shall make it unlawful for any Lender to make or maintain any Eurodollar Loan or to give effect to its obligations as contemplated hereby with respect to any Eurodollar Loan, then, by written notice to the Borrower and to the Administrative Agent:

(i)such Lender may declare that Eurodollar Loans will not thereafter (for the duration of such unlawfulness) be made by such Lender hereunder (or be continued for additional Interest Periods) and ABR Loans will not thereafter (for such duration) be converted into Eurodollar Loans, whereupon any request for a Eurodollar Borrowing or to convert an ABR Borrowing to a Eurodollar Borrowing or to continue a Eurodollar Borrowing, as applicable, for an additional Interest Period shall, as to such Lender only, be deemed a request for an ABR Loan (or a request to continue an ABR Loan as such for an additional Interest Period or to convert a Eurodollar Loan into an ABR Loan, as applicable), unless such declaration shall be subsequently withdrawn; and

(ii)such Lender may require that all outstanding Eurodollar Loans made by it be converted to ABR Loans, in which event all such Eurodollar Loans shall be automatically converted to ABR Loans, as of the effective date of such notice as provided in the last sentence of this paragraph.

34

Exhibit 4

In the event any Lender shall exercise its rights under clause (i) or (ii) of this paragraph, all payments and prepayments of principal that would otherwise have been applied to repay the Eurodollar Loans that would have been made by such Lender or the converted Eurodollar Loans of such Lender shall instead be applied to repay the ABR Loans made by such Lender in lieu of, or resulting from the conversion of, such Eurodollar Loans, as applicable. For purposes of this paragraph, a notice to the Borrower by any Lender shall be effective as to each Eurodollar Loan made by such Lender, if lawful, on the last day of the Interest Period currently applicable to such Eurodollar Loan; in all other cases such notice shall be effective on the date of receipt by the Borrower.

Section 3.6.Break Funding Payments. In the event of (3) the payment or prepayment (voluntary or otherwise) of any principal of any Eurodollar Loan other than on the last day of an Interest Period applicable thereto (including as a result of an Event of Default), (3) the conversion of any Eurodollar Loan other than on the last day of the Interest Period applicable thereto, (3) the failure to borrow, convert, continue or prepay any Eurodollar Loan on the date specified in any notice delivered pursuant hereto (regardless of whether such notice may be revoked under Section 2.7(b) and is revoked in accordance therewith), or (3) the assignment of any Eurodollar Loan other than on the last day of the Interest Period or maturity date applicable thereto as a result of a request by the Borrower pursuant to Section 3.8, then, in any such event, the Borrower shall compensate each Lender for the loss, cost and expense attributable to such event. In the case of a Eurodollar Loan, such loss, cost or expense to any Lender shall be deemed to include an amount determined by such Lender to be the excess, if any, of (3) the amount of interest that would have accrued on the principal amount of such Loan had such event not occurred, at the Adjusted LIBO Rate that would have been applicable to such Loan, for the period from the date of such event to the last day of the then current Interest Period therefor (or, in the case of a failure to borrow, convert or continue, for the period that would have been the Interest Period for such Loan), over (3) the amount of interest that would accrue on such principal amount for such period at the interest rate that such Lender would bid were it to bid, at the commencement of such period, for dollar deposits of a comparable amount and period from other banks in the eurodollar market. A certificate of any Lender setting forth any amount or amounts that such Lender is entitled to receive pursuant to this Section shall be delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay such Lender the amount shown as due on any such certificate within 10 Business Days after receipt thereof.

Section 3.7.Withholding of Taxes; Gross-Up.

(a)Payments to be Free and Clear. Anyand all payments by or on account of any obligation of the Borrower under any Loan Document shall be made without deduction or withholding for any Taxes, except as required by applicable law. If any applicable law (as determined in the good faith discretion of an applicable withholding agent) requires the deduction or withholding of any Tax from any such payment by a withholding agent, then the applicable withholding agent shall be entitled to make such deduction or withholding and shall timely pay the full amount deducted or withheld to the relevant Governmental Authority in accordance with applicable law and, if such Tax is an Indemnified Tax, then the sum payable by the Borrower shall be increased as necessary so that after such deduction or withholding has been made (including such deductions and withholdings applicable to additional sums payable under this Section) the applicable Recipient receives an amount equal to the sum it would have received had no such deduction or withholding been made.

(b)Payment of Other Taxes by the Borrower. The Borrower shall timely pay to the relevant Governmental Authority in accordance with applicable law, or at the option of the Administrative Agent timely reimburse it for, Other Taxes.

35

Exhibit 4

(c)Evidence of Payments. As soon as practicable after any payment of Taxes by the Borrower to a Governmental Authority pursuant to this Section, the Borrower shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent.

(d)Indemnification by the Borrower. The Borrower shall indemnify each Recipient, within 10 Business Days after demand therefor, for the full amount of any Indemnified Taxes (including Indemnified Taxes imposed or asserted on or attributable to amounts payable under this Section) payable or paid by such Recipient or required to be withheld or deducted from a payment to such Recipient and any reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to the Borrower by a Lender (with a copy to the Administrative Agent), or by the Administrative Agent on its own behalf or on behalf of a Lender, shall be conclusive absent manifest error.

(e)Indemnification by the Lenders. Each Lender shall severally indemnify the Administrative Agent, within 10 days after demand therefor, for (i) any Indemnified Taxes attributable to such Lender (but only to the extent that the Borrower has not already indemnified the Administrative Agent for such Indemnified Taxes and without limiting the obligation of the Borrower to do so), (ii) any Taxes attributable to such Lender’s failure to comply with the provisions of Section 10.4(d)relating to the maintenance of a Participant Register and (iii) any Excluded Taxes attributable to such Lender, in each case, that are payable or paid by the Administrative Agent in connection with any Loan Document, and any reasonable expenses arising therefrom or with respect thereto, whether or not such Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to any Lender by the Administrative Agent shall be conclusive absent manifest error. Each Lender hereby authorizes the Administrative Agent to setoff and apply any and all amounts at any time owing to such Lender under any Loan Document or otherwise payable by the Administrative Agent to the Lender from any other source against any amount due to the Administrative Agent under this paragraph (e).

(f)Status of Lenders.

(i)Any Lender that is entitled to an exemption from or reduction of withholding Tax with respect to payments made under any Loan Document shall deliver to the Borrower and the Administrative Agent, at the time or times reasonably requested by the Borrower or the Administrative Agent, such properly completed and executed documentation reasonably requested by the Borrower or the Administrative Agent as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition, any Lender, if reasonably requested by the Borrower or the Administrative Agent, shall deliver such other documentation prescribed by applicable law or reasonably requested by the Borrower or the Administrative Agent as will enable the Borrower or the Administrative Agent to determine whether or not such Lender is subject to backup withholding or information reporting requirements. Notwithstanding anything to the contrary in the preceding two sentences, the completion, execution and submission of such documentation (other than such documentation set forth in Section 3.7(f)(ii)(A), (ii)(B) and (ii)(D) below) shall not be required if in the Lender’s reasonable judgment such completion, execution or submission would subject such Lender to any

36

Exhibit 4

material unreimbursed cost or expense or would materially prejudice the legal or commercial position of such Lender.

(ii)Without limiting the generality of the foregoing, in the event that the Borrower is a U.S. Person,

(A)any Lender that is a U.S. Person shall deliver to the Borrower and the Administrative Agent on or prior to the date on which such Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Administrative Agent), an executed copy of IRS Form W-9 certifying that such Lender is exempt from U.S. federal backup withholding tax;

(B)any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Borrower and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Administrative Agent), whichever of the following is applicable:

1.in the case of a Foreign Lender claiming the benefits of an income tax treaty to which the United States is a party (x) with respect to payments of interest under any Loan Document, an executed copy of IRS Form W-8BEN-E or IRS Form W-8BEN establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “interest” article of such tax treaty and (y) with respect to any other applicable payments under any Loan Document, IRS Form W-8BEN-E or IRS Form W-8BEN establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “business profits” or “other income” article of such tax treaty;

2.in the case of a Foreign Lender claiming that its extension of credit will generate U.S. effectively connected income, an executed copy of IRS Form W-8ECI;

3.in the case of a Foreign Lender claiming the benefits of the exemption for portfolio interest under Section 881(c) of the Code, (x) a certificate substantially in the form of Exhibit E-1 to the effect that such Foreign Lender is not a “bank” within the meaning of Section 881(c)(3)(A) of the Code, a “10 percent shareholder” of the Borrower within the meaning of Section 881(h)(3)(B) of the Code, or a “controlled foreign corporation” described in Section 881(c)(3)(C) of the Code (a “U.S. Tax Compliance Certificate”) and (y) an executed copy of IRS Form W-8BEN-E or IRS Form W-8BEN; or

4.to the extent a Foreign Lender is not the beneficial owner, an executed copy of IRS Form W-8IMY, accompanied by IRS Form W-8ECI, IRS Form W-8BEN-E, IRS Form W-8BEN, a U.S. Tax Compliance Certificate substantially in the form of Exhibit E-2 or Exhibit E-3, IRS Form W-9, and/or other certification documents from each beneficial owner, as applicable; provided that if the Foreign Lender is a partnership and one or more direct or

37

Exhibit 4

indirect partners of such Foreign Lender are claiming the portfolio interest exemption, such Foreign Lender may provide a U.S. Tax Compliance Certificate substantially in the form of Exhibit E-4 on behalf of each such direct and indirect partner;

(C)any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Borrower and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Administrative Agent), executed copies of any other form prescribed by applicable law as a basis for claiming exemption from or a reduction in U.S. federal withholding Tax, duly completed, together with such supplementary documentation as may be prescribed by applicable law to permit the Borrower or the Administrative Agent to determine the withholding or deduction required to be made; and

(D)if a payment made to a Lender under any Loan Document would be subject to U.S. federal withholding Tax imposed by FATCA if such Lender were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Lender shall deliver to the Borrower and the Administrative Agent at the time or times prescribed by law and at such time or times reasonably requested by the Borrower or the Administrative Agent such documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by the Borrower or the Administrative Agent as may be necessary for the Borrower and the Administrative Agent to comply with their obligations under FATCA and to determine that such Lender has complied with such Lender’s obligations under FATCA or to determine the amount to deduct and withhold from such payment. Solely for purposes of this clause (D), “FATCA” shall include any amendments made to FATCA after the date of this Agreement

Each Lender agrees that if any form or certification it previously delivered expires or becomes obsolete or inaccurate in any respect, it shall update such form or certification or promptly notify the Borrower and the Administrative Agent in writing of its legal inability to do so.

(g)Treatment of Certain Refunds. If any party determines, in its sole discretion exercised in good faith, that it has received a refund of any Taxes as to which it has been indemnified pursuant to this Section (including by the payment of additional amounts pursuant to this Section), it shall pay to the indemnifying party an amount equal to such refund (but only to the extent of indemnity payments made under this Section with respect to the Taxes giving rise to such refund), net of all out-of-pocket expenses (including Taxes) of such indemnified party and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund). Such indemnifying party, upon the request of such indemnified party, shall repay to such indemnified party the amount paid over pursuant to this paragraph (g) (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) in the event that such indemnified party is required to repay such refund to such Governmental Authority. Notwithstanding anything to the contrary in this paragraph (g), in no event will the indemnified party be required to pay any amount to an indemnifying party pursuant to this paragraph (g) the payment of which would place the indemnified party in a less favorable net after-tax position than

38

Exhibit 4

the indemnified party would have been in if the Tax subject to indemnification and giving rise to such refund had not been deducted, withheld or otherwise imposed and the indemnification payments or additional amounts with respect to such Tax had never been paid. This paragraph shall not be construed to require any indemnified party to make available its tax returns (or any other information relating to its taxes that it deems confidential) to the indemnifying party or any other Person.

(h)Survival. Each party’s obligations under this Section shall survive the resignation or replacement of the Administrative Agent or any assignment of rights by, or the replacement of, a Lender, the termination of the Commitments and the repayment, satisfaction or discharge of all obligations under any Loan Document.

(i)Defined Terms. For purposes of this Section, the term “applicable law” includes FATCA.

Section 3.8.Mitigation Obligations.

(a)Designation of a Different Lending Office.In the event that the Borrower becomes obligated to pay additional amounts to any Lender (or to any Governmental Authority for the account of any Lender) pursuant to Section 3.5, Section 3.6 or Section 3.7, then such Lender shall use reasonable efforts to designate a different lending office for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 3.5, Section 3.6 or Section 3.7, as the case may be, in the future, and (ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment.

(b)Replacement of Lenders. In the event that (3) the Borrower becomes obligated to pay additional amounts to any Lender (or to any Governmental Authority for the account of any Lender) pursuant to Section 3.5, Section 3.6 or Section 3.7, (3) any Lender becomes a Defaulting Lender, or (3) if any Lender has failed to consent to a proposed amendment, waiver, discharge or termination that under Section 10.2 requires the consent of all the Lenders and with respect to which the Required Lenders shall have granted their consent, then the Borrower may, at its sole cost and expense, within 60 days of the demand by such Lender for such additional amounts or the relevant default or action or inaction by such Lender, as the case may be, and subject to and in accordance with the provisions of Section 10.4 (with the Borrower obligated to pay any applicable processing and recordation fee), designate an Eligible Assignee (acceptable to the Administrative Agent) to purchase and assume all of such Lender’s interests, rights and obligations under the Loan Documents, without recourse to or warranty by or expense to, such Lender, for a purchase price equal to the outstanding principal amount of such Lender’s Loans plus any accrued but unpaid interest thereon and accrued but unpaid ticking fees in respect of such Lender’s Delayed Draw Commitment and any other amounts payable to such Lender hereunder, and to assume all the obligations of such Lender hereunder, and, upon such purchase, such Lender shall no longer be a party hereto or have any rights hereunder (except those that survive full repayment hereunder) and shall be relieved from all obligations to the Borrower hereunder, and the Eligible Assignee shall succeed to the rights and obligations of such Lender hereunder. No replacement of a Defaulting Lender pursuant to this Section 3.8 shall be deemed to be a waiver of any right that the Borrower, the Administrative Agent or any other Lender may have against such Defaulting Lender. The Borrower shall execute and deliver to such Eligible Assignee a Note. Notwithstanding anything herein to the contrary, in the event that a

Section 4.2.Authorization; Enforceability. The Transactions are within the corporate powers of the Borrower and have been duly authorized by all necessary corporate and, if required, equity holder action. Each Loan Document has been duly executed and delivered by the Borrower and constitutes a legal, valid and binding obligation thereof, enforceable in accordance with its terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting creditors’ rights generally and general principles of equity.

Section 4.3.Governmental Approvals; No Conflicts.

(a)The execution, delivery and performance by the Borrower of the Loan Documents and the borrowing of the Loans do not require any consent or approval of, registration or filing with, or any other action by, any Governmental Authority, except for (i) information filings to be made in the ordinary course of business, which filings are not a condition to the Borrower’s performance under the Loan Documents and (ii) such as have been obtained or made and are in full force and effect and not subject to any appeals period.

(b)The Transactions will not (i) violate the charter, by-laws or other organizational documents of the Borrower, (ii) violate any applicable law or regulation or any order of any Governmental Authority, (iii) violate or result in a default under any material indenture, agreement or other instrument binding upon the Borrower or its assets, or give rise to a right thereunder to require any payment to be made by the Borrower, and (iv) result in or require the creation or imposition of any Lien on any asset of the Borrower.

All such financial statements have been prepared in accordance with GAAP and fairly present in all material respects the consolidated financial condition and results of the operations of the Borrower and its Subsidiaries as of the dates and for the periods indicated therein.

(b)Since December 31, 2019, there has been no Material Adverse Change.

Section 4.5.Litigation. There are no actions, suits or proceedings by or before any arbitrator or Governmental Authority pending against or, to the knowledge of the Borrower, threatened in writing against or affecting the Borrower or any Subsidiary that (a) if adversely determined (and provided that there exists a reasonable possibility of such adverse determination), would reasonably be expected, individually or in the aggregate, to result in a Material Adverse Effect, except for any Disclosed Matters, and except that the commencement by the Borrower, any Subsidiary or any Governmental Authority of a rate proceeding, fuel adjustment clause audit or earnings review before such Governmental Authority shall not constitute such a pending or threatened action, suit or proceeding unless and until such Governmental Authority has made a final determination thereunder that would reasonably be expected to have a Material Adverse Effect, or (b) involve any Loan Document or the Transactions.

Section 4.6.Environmental Matters. Except for the Disclosed Matters, the Borrower and its Subsidiaries (a) are in compliance with Environmental Law, (b) have received all permits, licenses or other approvals required of them under applicable Environmental Law to conduct their respective businesses and (c) are in compliance with all terms and conditions of any such permit, license, or approval, except, in each case, such as could not reasonably be expected to result in a Material Adverse Effect.

ARTICLE 9.
THE ADMINISTRATIVE AGENT

Section 9.1.Appointment and Authority. Each of the Lenders hereby irrevocably appoints U.S. Bank National Association to act on its behalf as the Administrative Agent hereunder and under the other Loan Documents and authorizes the Administrative Agent to take such actions on its behalf and to exercise such powers as are delegated to the Administrative Agent by the terms hereof or thereof, together with such actions and powers as are reasonably incidental thereto. Except as otherwise provided in Section 9.6(c), the provisions of this Article IX are solely for the benefit of the Administrative Agent and the Lenders, and the Borrower shall not have rights as a third-party beneficiary of any of such provisions. It is understood and agreed that the use of the term “agent” herein or in any other Loan Documents (or any other similar term) with reference to the Administrative Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable law. Instead such term is used as a matter of market custom and is intended to create or reflect only an administrative relationship between contracting parties.

Section 9.2.Rights as a Lender. The Person serving as the Administrative Agent hereunder has the same rights and powers in its capacity as a Lender as any other Lender and may exercise them as though it were not the Administrative Agent, and the term “Lender” or “Lenders,” unless otherwise expressly indicated or unless the context otherwise requires, includes the Person serving as the Administrative Agent hereunder in its individual capacity. Such Person and its Affiliates may accept deposits from, lend money to, own securities of, act as the financial advisor or in any other advisory capacity for, and generally engage in any kind of business with, the Borrower or any Subsidiary or other Affiliate thereof as if such Person were not the Administrative Agent hereunder and without any duty to account therefor to the Lenders.

Section 9.3.Exculpatory Provisions.

(a)The Administrative Agent has no duties or obligations except those expressly set forth herein and in the other Loan Documents, and its duties hereunder are administrative in nature. Without limiting the generality of the foregoing, the Administrative Agent:

(i)is not subject to any fiduciary or other implied duties, regardless of whether a Default has occurred and is continuing;

(ii)has no duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby or by the other Loan Documents that the Administrative Agent is required to exercise as directed in writing by the Required Lenders (or such other number or percentage of the Lenders as is expressly provided for herein or in the other Loan Documents); provided that the

54

Exhibit 4

Administrative Agent is not required to take any action that, in the opinion of the Administrative Agent or its counsel, could expose the Administrative Agent to liability or is contrary to any Loan Document or applicable law, including for the avoidance of doubt any action that could be in violation of the automatic stay under any Debtor Relief Law or that could effect a forfeiture, modification or termination of property of a Defaulting Lender in violation of any Debtor Relief Law; and

(iii)does not, except as expressly set forth herein and in the other Loan Documents, have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to the Borrower or any of its Affiliates that is communicated to or obtained by the Person serving as the Administrative Agent or any of its Affiliates in any capacity.

(b)The Administrative Agent shall not be liable for any action taken or not taken by it (i) with the consent or at the request of the Required Lenders (or such other number or percentage of the Lenders as is necessary, or as the Administrative Agent believes in good faith is necessary), or (ii) in the absence of its own gross negligence or willful misconduct as determined by a court of competent jurisdiction by final and nonappealable judgment. The Administrative Agent shall be deemed not to have knowledge of any Default unless and until notice describing such Default is given to the Administrative Agent in writing by the Borrower or a Lender.

(c)The Administrative Agent is not responsible for and has no duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with this Agreement or any other Loan Document, (ii) the contents of any certificate, report or other document delivered hereunder or thereunder or in connection herewith or therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein or therein or the occurrence of any Default, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement, any other Loan Document or any other agreement, instrument or document, or (v) the satisfaction of any condition set forth in Article V or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent.

Section 9.4.Reliance by Administrative Agent. The Administrative Agent may rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing (including any electronic message, Internet or intranet website posting or other distribution) believed by it to be genuine and to have been signed, sent or otherwise authenticated by the proper Person. The Administrative Agent also may rely upon any statement made to it orally or by telephone and believed by it to have been made by the proper Person and shall not incur any liability for relying thereon. In determining compliance with any condition hereunder to the making of a Loan that by its terms must be fulfilled to the satisfaction of a Lender, the Administrative Agent may presume that such condition is satisfactory to such Lender unless the Administrative Agent has received notice to the contrary from such Lender prior to the making of such Loan. The Administrative Agent may consult with legal counsel (who may be counsel for the Borrower), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.

Section 9.5.Delegation of Duties. The Administrative Agent may perform any and all of its duties and exercise its rights and powers hereunder or under any other Loan Document by or through any one or more sub-agents appointed by the Administrative Agent. The Administrative Agent and any such

55

Exhibit 4

sub-agent may perform any and all of their duties and exercise their rights and powers by or through their respective Related Parties. The exculpatory provisions of this Article IX apply to any such sub-agent and to the Related Parties of the Administrative Agent and any such sub-agent and apply to their respective activities in connection with the syndication of the facilities hereunder as well as activities as Administrative Agent. The Administrative Agent is not responsible for the negligence or misconduct of any sub-agents except to the extent that a court of competent jurisdiction determines in a final and nonappealable judgment that the Administrative Agent acted with gross negligence or willful misconduct in the selection of such sub-agents.

Section 9.6.Resignation of Administrative Agent.

(a)The Administrative Agent may at any time give notice of its resignation to the Lenders and the Borrower. Upon receipt of any such notice of resignation, the Required Lenders may, in consultation with the Borrower, appoint a successor. If no such successor has been so appointed by the Required Lenders and has accepted such appointment 30 days after the retiring Administrative Agent gives notice of its resignation (or such earlier day as is agreed by the Required Lenders) (the “Resignation Effective Date”), then the retiring Administrative Agent may (but is not obligated to), on behalf of the Lenders, appoint a successor Administrative Agent; provided that in no event may any such successor Administrative Agent be a Defaulting Lender. Whether or not a successor has been appointed, such resignation shall become effective in accordance with such notice on the Resignation Effective Date

(b)If the Person serving as Administrative Agent is a Defaulting Lender pursuant to clause (d) of the definition thereof, the Required Lenders may, to the extent permitted by applicable Law, by notice in writing to the Borrower and such Person remove such Person as Administrative Agent and, in consultation with the Borrower, appoint a successor. If no such successor has been so appointed by the Required Lenders and has accepted such appointment 30 days after the Administrative Agent receives notice of its removal (or such earlier day as is agreed by the Required Lenders) (the “Removal Effective Date”), then such removal shall nonetheless become effective in accordance with such notice on the Removal Effective Date.

(c)With effect from the Resignation Effective Date or the Removal Effective Date (as applicable) (i) the retiring or removed Administrative Agent shall be discharged from its duties and obligations hereunder and under the other Loan Documents and (ii) except for any indemnity payments owed to the retiring or removed Administrative Agent, all payments, communications and determinations provided to be made by, to or through the Administrative Agent shall instead be made by or to each Lender directly, until such time, if any, as the Required Lenders appoint a successor Administrative Agent as provided for above. Upon the acceptance of a successor’s appointment as Administrative Agent hereunder, such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring or removed Administrative Agent (other than any rights to indemnity payments owed to the retiring or removed Administrative Agent), and the retiring or removed Administrative Agent shall be discharged from all of its duties and obligations hereunder or under the other Loan Documents. The fees payable by the Borrower to a successor Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After the retiring or removed Administrative Agent’s resignation or removal hereunder and under the other Loan Documents, the provisions of this Article IX and Section 10.3 shall continue in effect for the benefit of such retiring or removed Administrative Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while the retiring or removed Administrative Agent was acting as Administrative Agent.

56

Exhibit 4

Section 9.7.Non-Reliance on Agents and Other Lenders. Each Lender acknowledges that it has, independently and without reliance upon the Administrative Agent or any other Lender or any of their Related Parties and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender also acknowledges that it will, independently and without reliance upon the Administrative Agent or any other Lender or any of their Related Parties and based on such documents and information as it from time to time deems appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any other Loan Document or any related agreement or any document furnished hereunder or thereunder.

Section 9.8.No Other Duties. Anything herein to the contrary notwithstanding, none of the Arranger nor the Co-Documentation Agents has any powers, duties or responsibilities under this Agreement or any of the other Loan Documents, except in its capacity, as applicable, as the Administrative Agent or a Lender.

Section 9.9.Administrative Agent May File Proofs of Claim. In case of the pendency of any proceeding under any Debtor Relief Law, the Administrative Agent (irrespective of whether the principal of any Loan is then due and payable as herein expressed or by declaration or otherwise and irrespective of whether the Administrative Agent has made any demand on the Borrower) shall be entitled and empowered (but not obligated) by intervention in such proceeding or otherwise:

(a)to file and prove a claim for the whole amount of the principal and interest owing and unpaid in respect of the Loans and all other obligations that are owing and unpaid and to file such other documents as may be necessary or advisable to have the claims of the Lenders and the Administrative Agent (including any claim for the reasonable compensation, expenses, disbursements and advances of the Lenders and the Administrative Agent and their respective agents and counsel and all other amounts due the Lenders and the Administrative Agent) allowed in such judicial proceeding; and

(b)to collect and receive any monies or other property payable or deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Lender to make such payments to the Administrative Agent and, if the Administrative Agent consents to the making of such payments directly to the Lenders, to pay to the Administrative Agent any amount due for the reasonable compensation, expenses, disbursements and advances of the Administrative Agent and its agents and counsel, and any other amounts due the Administrative Agent under Section 10.3.

No waiver of any provision of any Loan Document or consent to any departure by the Borrower therefrom shall in any event be effective unless the same shall be permitted by paragraph (b) of this Section, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given.

(b)Subject to Section 3.4(b) and (c) and Section 10.2(c) below, neither any Loan Document nor any provision thereof may be waived, amended or modified except pursuant to an agreement or agreements in writing entered into by the Borrower and the Required Lenders or by the Borrower and the Administrative Agent with the consent of the Required Lenders, provided that no such agreement shall (10) increase the Commitment of any Lender without the written consent of such Lender, (10) reduce the principal amount of any Loan, or reduce the rate of any interest, or reduce any fees, payable under the Loan Documents, without the written consent of each Credit Party affected thereby, (10) postpone the date of payment at stated maturity of any Loan, or the date of any interest or any fees payable under the Loan Documents, or reduce the amount of, waive or excuse any such payment, or postpone the stated termination or expiration of the Commitments without the written consent of each Credit Party affected thereby, (10) change any provision hereof in a manner that would alter the pro rata sharing of payments required by Section 2.8(b) or 2.8(c), without the written consent of each Credit Party affected thereby, and (10) change any of the provisions of this Section or the definition of the term “Required Lenders” or any other provision hereof specifying the number or percentage of Lenders required to waive, amend or modify any rights hereunder or make any determination or grant any consent hereunder, or change the currency in which Loans are to be made or payment under the Loan Documents is to be made, or add additional borrowers, without the written consent of each Lender, and providedfurther that no such agreement shall amend, modify or otherwise affect the rights or duties of the Administrative Agent hereunder without the prior written consent of the Administrative Agent.

(b)Indemnification by the Borrower. The Borrower shall indemnify each Credit Party and each Related Party thereof (each such Person being called an “Indemnitee”) against, and hold each Indemnitee harmless from, any and all losses, claims, damages, liabilities and related expenses, including the reasonable fees, charges and disbursements of any counsel for any Indemnitee, incurred by or asserted against any Indemnitee arising out of, in connection with, or as a result of (10) the execution or delivery of any Loan Document or any agreement or instrument contemplated thereby, the performance by the parties to the Loan Documents of their respective obligations thereunder or the consummation of the Transactions or any other transactions contemplated thereby, (10) any Loan or the use of the proceeds thereof, (10) any actual or alleged presence or release of Hazardous Materials on or from any property owned or operated by the Borrower or any of the Subsidiaries, or any liability under any Environmental Law related in any way to the Borrower or any of the Subsidiaries or (10) any actual or prospective claim, litigation, investigation or proceeding relating to any of the foregoing, whether based on contract, tort or any other theory and regardless of whether any Indemnitee is a party thereto, provided that such indemnity shall not, as to any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from the gross negligence or willful misconduct of such Indemnitee or a breach in bad faith by such Indemnitee or arising solely from claims between or among one or more Indemnitees.

(c)Reimbursement by Lenders.

(b)Assignments by Lenders. Any Lender may (and if demanded by Borrower pursuant to Section 3.8 shall to the extent required thereby) at any time assign to one or more Eligible Assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitments and the Loans at the time owing to it); provided that any such assignment shall be subject to the following conditions:

(i)Minimum Amounts.

(A)In the case of an assignment of the entire remaining amount of the assigning Lender’s Commitments and the Loans at the time owing to it or in the case of an assignment to a Lender, an Affiliate of a Lender or an Approved Fund, no minimum amount need be assigned; and

(B)In any case not described in paragraph (b)(i)(A) of this Section, the aggregate amount of the Commitment (which for this purpose includes Loans outstanding thereunder) or, if the Commitment is not then in effect, the principal outstanding balance of the Loans of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Administrative Agent or, if “trade date” is specified in the Assignment and Assumption, as of the trade date) shall not be less than $5,000,000 unless each of the

62

Exhibit 4

Administrative Agent and, so long as no Event of Default has occurred and is continuing, the Borrower otherwise consents (each such consent not to be unreasonably withheld or delayed).

(ii)Proportionate Amounts. Each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement with respect to the Loan or the Commitment assigned.

(iii)Required Consents. For each such assignment:

(A)the consent of the Borrower (such consent not to be unreasonably withheld) shall be required unless (x) an Event of Default has occurred and is continuing at the time of such assignment or (y) such assignment is to a Lender, an Affiliate of a Lender or an Approved Fund; provided that the Borrower shall be deemed to have consented to any such assignment unless it shall object thereto by written notice to the Administrative Agent within five Business Days after having received notice thereof; and

(B)the consent of the Administrative Agent (such consent not to be unreasonably withheld or delayed) shall be required for assignments if such assignment is to an Eligible Assignee that is not a Lender, an Affiliate of such Lender or an Approved Fund with respect to such Lender.

(iv)Assignment and Assumption.

(v)No Assignment to Borrower. No such assignment shall be made to the Borrower or any of the Borrower’s Affiliates or Subsidiaries.

(vi)No Assignment to Natural Persons. No such assignment shall be made to a natural person.

Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this paragraph shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with paragraph (d) of this Section.

(c)Register.

63

Exhibit 4

(i)The Administrative Agent, acting solely for this purpose as an agent of the Borrower, shall maintain at one of its offices in New York, New York a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitments of, and principal amounts of the Loans owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive, and the Borrower, the Administrative Agent and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

(ii)Upon its receipt of (x) a duly completed Assignment and Assumption executed by an assigning Lender and an assignee or (y) to the extent applicable, an agreement incorporating an Assignment and Assumption by reference pursuant to an Approved Electronic Platform as to which the Administrative Agent and the parties to the Assignment and Assumption are participants, the assignee’s completed Administrative Questionnaire (unless the assignee shall already be a Lender hereunder), the processing and recordation fee referred to in paragraph (b) of this Section and any written consent to such assignment required by paragraph (b) of this Section, the Administrative Agent shall accept such Assignment and Assumption and record the information contained therein in the Register; provided that if either the assigning Lender or the assignee shall have failed to make any payment required to be made by it pursuant to Section 2.4(b)  or 10.3(c), the Administrative Agent shall have no obligation to accept such Assignment and Assumption and record the information therein in the Register unless and until such payment shall have been made in full, together with all accrued interest thereon. No assignment shall be effective for purposes of this Agreement unless it has been recorded in the Register as provided in this paragraph

(d)Participations. Any Lender may at any time, without the consent of, but with notice to, the Borrower and the Administrative Agent (provided that any failure to give such notice shall not impair the effectiveness of such participation except as expressly provided in paragraph (e) of this Section), sell participations to any Person (other than a natural person or the Borrower or any of the Borrower’s Affiliates or Subsidiaries) (each, a “Participant”) in all or a portion of such Lender’s rights and/or obligations under this Agreement (including all or a portion of its Commitment and/or the Loans owing to it); provided that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, (iii) such Lender shall remain the holder of any Note for all purposes of this Agreement and (iv) the Borrower, the Administrative Agent and each Credit Party shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Notwithstanding the foregoing, in no event may a participation be granted to any entity which is not a commercial bank, finance company, insurance company or other financial institution or fund (whether a corporation, partnership or other entity) engaged generally in making, purchasing or otherwise investing in commercial loans in the ordinary course of its business without the express prior written consent of the Borrower.

Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any

64

Exhibit 4

amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver with respect to the following matters described in clauses (ii) and (iii) of the first proviso in Section 10.2(b) that directly affects such Participant. Subject to paragraph (e) of this Section, the Borrower agrees that each Participant shall be entitled to the benefits of Sections 3.5, 3.6 and 3.7 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section but (x) shall not be entitled to recover greater amounts under any such Section than the selling Lender would be entitled to recover and (y) shall be subject to replacement by the Borrower under Section 3.8 to the same extent as if it were a Lender; provided that such replacement Participant shall be a commercial bank, finance company, insurance company or other financial institution or fund (whether a corporation, partnership or other entity) engaged generally in making, purchasing or otherwise investing in commercial loans in the ordinary course of its business. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 10.8as though it were a Lender, provided such Participant agrees to be subject to Section 2.8(c) as though it were a Lender.

Each Lender that sells a participation shall, acting solely for this purpose as a non-fiduciary agent of the Borrower, maintain a register on which it enters the name and address of each Participant and the principal amounts (and stated interest) of each Participant’s interest in the Loans or other obligations under the Loan Documents (the “Participant Register”); provided that no Lender shall have any obligation to disclose all or any portion of the Participant Register (including the identity of any Participant or any information relating to a Participant’s interest in any Loans or its other obligations under any Loan Document) to any Person except to the extent that such disclosure is necessary to establish that such Loan or other obligation is in registered form under Section 5f.103-1(c) of the United States Treasury Regulations. The entries in the Participant Register shall be conclusive absent manifest error, and such Lender shall treat each Person whose name is recorded in the Participant Register as the owner of such participation for all purposes of this Agreement notwithstanding any notice to the contrary. For the avoidance of doubt, the Administrative Agent (in its capacity as Administrative Agent) shall have no responsibility for maintaining a Participant Register.

(e)Limitations upon Participant Rights. A Participant shall not be entitled to receive any greater payment under Sections 3.5 or 3.7 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the Borrower’s prior written consent. A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 3.7 unless the Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrower, to comply with Section 3.7(f) as though it were a Lender.

(f)Certain Pledges. Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank; provided that no such pledge or assignment shall release such Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

(g)Defaulting Lenders. Notwithstanding any provision in this Section 10.4 to the contrary, if any Lender becomes a Defaulting Lender, then the provisions of Section 2.9 shall apply for so long as such Lender is a Defaulting Lender.

65

Exhibit 4

Section 10.5.Survival. All covenants, agreements, representations and warranties made by the Borrower herein and in the certificates or other instruments prepared or delivered in connection with or pursuant to this Agreement or any other Loan Document shall be considered to have been relied upon by the other parties hereto and shall survive the execution and delivery of any Loan Document and the making of any Loans, regardless of any investigation made by any such other party or on its behalf and notwithstanding that any Credit Party may have had notice or knowledge of any Default or incorrect representation or warranty at the time any credit is extended hereunder, and shall continue in full force and effect as long as the principal of or any accrued interest on any Loan or any fee or any other amount payable under the Loan Documents is outstanding and unpaid and so long as the Commitments have not expired or terminated. The provisions of Sections 3.5, 3.6, 3.7, 10.3, 10.9, 10.10 and Article 9 shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated hereby, the repayment of the Loans and the termination of the Commitments or the termination of this Agreement or any provision hereof.

Section 10.6.Counterparts; Integration; Effectiveness.

(a)This Agreement may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original, but all of which, when taken together, shall constitute a single contract. This Agreement and any separate letter agreements with respect to fees payable to any Credit Party or the syndication of the credit facility established hereunder constitute the entire contract among the parties relating to the subject matter hereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof. Except as provided in Section 5.1, this Agreement shall become effective as of the date set forth in the preamble to this Agreement when it shall have been executed by the Administrative Agent and when the Administrative Agent shall have received counterparts hereof which, when taken together, bear the signatures of each of the other parties and thereafter shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns.

(b)Delivery of an executed counterpart of a signature page of this Agreement by telecopy, emailed pdf. or any other electronic means that reproduces an image of the actual executed signature page shall be effective as delivery of a manually executed counterpart of this Agreement.

Section 10.7.Severability. In the event any one or more of the provisions contained in this Agreement should be held invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein shall not in any way be affected or impaired thereby (it being understood that the invalidity of a particular provision in a particular jurisdiction shall not in and of itself affect the validity of such provision in any other jurisdiction). The parties shall endeavor in good faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions

66

Exhibit 4

the economic effect of which comes as close as possible to that of the invalid, illegal or unenforceable provisions.

Section 10.8.Right of Set‑off. If an Event of Default shall have occurred and be continuing, and the acceleration of the obligations owing in connection with the Loan Documents, or at any time upon the occurrence and during the continuance of an Event of Default under paragraph (a) of Article 8, each of the Lenders and their respective Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by applicable law, to set‑off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other obligations at any time owing by it to or for the credit or the account of the Borrower against any of and all the obligations of the Borrower now or hereafter existing under this Agreement and the other Loan Documents held by it, irrespective of whether or not it shall have made any demand therefor and although such obligations may be unmatured. The rights of each of the Lenders and their respective Affiliates under this Section are in addition to other rights and remedies (including other rights of set‑off) that it may have. Each Lender agrees promptly to notify the Borrower and the Administrative Agent after any such set off and application made by such Lender, provided that the failure to give such notice shall not affect the validity of such set off and application.

(a)This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York.

(b)The Borrower irrevocably and unconditionally agrees that it will not commence any action, litigation or proceeding of any kind or description, whether in law or equity, whether in contract or in tort or otherwise, against the Administrative Agent, any Lender, or any Related Party of the foregoing in any way relating to this Agreement or any other Loan Document or the transactions relating hereto or thereto, in any forum other than the courts of the State of New York sitting in New York County, and of the United States District Court for the Southern District of New York, and any appellate court from any thereof, and each of the parties hereto irrevocably and unconditionally submits to the jurisdiction of such courts and agrees that all claims in respect of any such action, litigation or proceeding may be heard and determined in such state court or, to the fullest extent permitted by Applicable Law, in such federal court.

The Borrower agrees that it will not assert any claim against any Credit Party based on an alleged breach of fiduciary duty by such Credit Party in connection with this Agreement and the transactions contemplated hereby. Additionally, the Borrower acknowledges and agrees that no Credit Party is advising the Borrower as to any legal, tax, investment, accounting, regulatory or any other matters in any jurisdiction. The Borrower shall consult with its own advisors concerning such matters and shall be responsible for making its own independent investigation and appraisal of the transactions contemplated herein or in the other Loan Documents, and the Credit Parties shall have no responsibility or liability to the Borrower with respect thereto.

(b) The Borrower further acknowledges and agrees, and acknowledges its Subsidiaries’ understanding, that each Credit Party, together with its Affiliates, is a full service securities or banking firm engaged in securities trading and brokerage activities as well as providing investment banking and other financial services.

No Credit Party will use confidential information obtained from the Borrower by virtue of the transactions contemplated by the Loan Documents or its other relationships with the Borrower in connection with the performance by such Credit Party of services for other companies, and no Credit Party will furnish any such information to other companies. The Borrower also acknowledges that no Credit Party has any obligation to use in connection with the transactions contemplated by the Loan Documents, or to furnish to the Borrower, confidential information obtained from other companies.

Section 10.17.CoBank Equity and Security.

(a)So long as CoBank (or its Affiliate) is a Lender hereunder, the Borrower will (i) maintain its status as an entity eligible to borrow from CoBank and (ii) acquire equity in CoBank in such amounts and at such times as CoBank may require in accordance with CoBank’s Bylaws and Capital Plan, except that the maximum amount of equity that the Borrower may be required to purchase in CoBank in connection with the Loans made by CoBank (or its affiliate) may not exceed the maximum amount permitted by the Bylaws and the Capital Plan at the time this Agreement is entered into. The Borrower acknowledges receipt of a copy of (x) CoBank’s most recent annual report, and if more recent, CoBank’s latest quarterly report, (y) CoBank’s Notice to Prospective Stockholders and (iii) CoBank’s Bylaws and Capital Plan, which describe the nature of all of the Borrower’s cash patronage, stock and other equities in CoBank acquired in connection with its patronage loan from CoBank (or its Affiliate) (the “CoBank Equities”) as well as capitalization requirements, and agrees to be bound by the terms thereof.

CoBank reserves the right to assign or sell participations in all or any part of its (or its Affiliate’s) Commitments or outstanding Loans hereunder on a non-patronage basis.

(c)Each party hereto acknowledges that CoBank has a statutory first lien pursuant to the Farm Credit Act of 1971 (as amended from time to time) on all CoBank Equities that the Borrower may now own or hereafter acquire, which statutory lien shall be for CoBank’s (or its Affiliate’s) sole and exclusive benefit. The CoBank Equities shall not constitute security for the obligations due to any other Lender. To the extent that any of the Loan Documents create a Lien on the CoBank Equities or on patronage accrued by CoBank for the account of the Borrower (including, in each case, proceeds thereof), such Lien shall be for CoBank’s (or its Affiliate’s) sole and exclusive benefit and shall not be subject to pro rata sharing hereunder. Neither the CoBank Equities nor any accrued patronage shall be offset against the obligations hereunder, except that, in the event of an Event of Default, CoBank may elect, solely at its discretion, to apply the cash portion of any patronage distribution or retirement of equity to amounts owed to CoBank or its Affiliate under this Agreement, whether or not such amounts are currently due and payable. The Borrower acknowledges that any corresponding tax liability associated with such application is the sole responsibility of the Borrower. CoBank shall have no obligation to retire the CoBank Equities upon any Default or any other default by the Borrower, or at any other time, either for application to the Loans or other obligations under this Agreement or otherwise.

Section 10.18.Acknowledgement and Consent to Bail-In of EEA Financial Institutions. Notwithstanding anything to the contrary in any Loan Document or in any other agreement, arrangement

70

Exhibit 4

or understanding among any such parties, each party hereto acknowledges that any liability of any EEA Financial Institution arising under any Loan Document may be subject to the Write-Down and Conversion Powers of an EEA Resolution Authority and agrees and consents to, and acknowledges and agrees to be bound by:

(a)the application of any Write-Down and Conversion Powers by an EEA Resolution Authority to any such liabilities arising hereunder which may be payable to it by any party hereto that is an EEA Financial Institution; and

(b)the effects of any Bail-In Action on any such liability, including, if applicable:

(i)a reduction in full or in part or cancellation of any such liability;

(ii)a conversion of all, or a portion of, such liability into shares or other instruments of ownership in such EEA Financial Institution, its parent entity, or a bridge institution that may be issued to it or otherwise conferred on it, and that such shares or other instruments of ownership will be accepted by it in lieu of any rights with respect to any such liability under this Agreement or any other Loan Document; or

(iii)the variation of the terms of such liability in connection with the exercise of the Write-Down and Conversion Powers of any EEA Resolution Authority.

Section 10.19.Acknowledgement Regarding Any Supported QFCs. To the extent that the Loan Documents provide support, through a guarantee or otherwise, for Hedge Agreements or any other agreement or instrument that is a QFC (such support “QFC Credit Support” and each such QFC a “Supported QFC”), the parties acknowledge and agree as follows with respect to the resolution power of the Federal Deposit Insurance Corporation under the Federal Deposit Insurance Act and Title II of the Dodd-Frank Wall Street Reform and Consumer Protection Act (together with the regulations promulgated thereunder, the “U.S. Special Resolution Regimes”) in respect of such Supported QFC and QFC Credit Support (with the provisions below applicable notwithstanding that the Loan Documents and any Supported QFC may in fact be stated to be governed by the laws of the State of New York and/or of the United States or any other state of the United States):

In the event a Covered Entity that is party to a Supported QFC (each, a “Covered Party”) becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer of such Supported QFC and the benefit of such QFC Credit Support (and any interest and obligation in or under such Supported QFC and such QFC Credit Support, and any rights in property securing such Supported QFC or such QFC Credit Support) from such Covered Party will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if the Supported QFC and such QFC Credit Support (and any such interest, obligation and rights in property) were governed by the laws of the United States or a state of the United States. In the event a Covered Party or a BHC Act Affiliate of a Covered Party becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under the Loan Documents that might otherwise apply to such Supported QFC or any QFC Credit Support that may be exercised against such Covered Party are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if the Supported QFC and the Loan Documents were governed by the laws of the United States or a state of the United States. Without limitation of the foregoing, it is understood and agreed that rights and remedies of the parties with respect

71

Exhibit 4

to a Defaulting Lender shall in no event affect the rights of any Covered Party with respect to a Supported QFC or any QFC Credit Support.

ALLETE, Inc. reports first quarter earnings of $1.28 per share

Temporarily suspending 2020 guidance due to uncertainties with COVID-19

DULUTH, Minn. - ALLETE, Inc. (NYSE: ALE) today reported first quarter 2020 earnings of $1.28 per share on net income of $66.3 million. Last year’s results were $1.37 per share on net income of $70.5 million. Results in the first quarter of 2019 included a 19 cent per share gain from the sale of U.S. Water Services offset by 2 cents per share of U.S. Water Services operating results prior to the sale.

“This is a challenging time for everyone, and our priority is ensuring the safety of our employees, our families, our customers, and our communities, while we continue to provide the safe and reliable energy and water services that have never been more essential than they are today,” said ALLETE President and Chief Executive Officer Bethany Owen. “Although results from the first quarter of the year were in-line with our expectations, these results may not be indicative of the remainder of the year, as we cannot predict at this time the extent and duration of the effects of COVID-19 on our results of operations for the rest of 2020.”

“ALLETE’s businesses performed as expected in the first quarter, are fundamentally sound and have ample liquidity to meet our needs, including but not limited to significant growth related investments during the year. Because of the broad economic uncertainties related to COVID-19 and the potential financial impact, especially on our regulated business segment, at this time, we are unable to provide a sufficiently reliable update to our 2020 earning guidance, and accordingly we are temporarily suspending our 2020 guidance. We will continue to assess the impacts of the COVID-19 pandemic on the results of our operations, and may be able to better quantify the impacts in the second half of the year.” said ALLETE Senior Vice President and Chief Financial Officer Bob Adams.

ALLETE’s Regulated Operations segment, which includes Minnesota Power, Superior Water, Light and Power (SWL&P) and the Company’s investment in the American Transmission Co., recorded net income of $57.5 million, compared to $51.5 million in the first quarter of 2019. Earnings reflect higher net income at Minnesota Power primarily due to the implementation of interim rates on January 1, 2020, increased cost recovery rider revenue and year over year benefits of adopting a new fuel adjustment methodology in 2020. These increases were partially offset by higher expenses and lower kilowatt-hour sales to residential, commercial and municipal customers. Net income at SWL&P decreased from last year due to lower gas and kWh sales to commercial and residential customers as a result of warmer winter temperatures in 2020 compared to 2019.

ALLETE Clean Energy recorded first quarter 2020 net income of $11.7 million compared to $5.8 million in 2019. Net income in 2020 included $2.3 million of additional production tax credits generated compared to 2019, higher revenue resulting from higher wind resources and availability, and earnings from the Glen Ullin wind energy facility which commenced operations in December 2019. Net income in 2020 also included additional income tax benefit which varies quarter to quarter based on an estimated effective tax rate.

Corporate and Other businesses, which include BNI Energy and ALLETE Properties, recorded a net loss of $2.9 million in 2020 compared to net income of $14.3 million in 2019. Net income in 2019 included a gain on the sale of U.S. Water Services of $9.9 million after-tax. Net income in 2020 included lower earnings from marketable

equity securities held in certain benefit trusts. Net income in 2020 also reflected additional income tax expense which varies quarter to quarter based on an estimated annual effective tax rate.

Details of the Company’s outlook and status of 2020 earnings guidance were filed as part of today’s Form 8-K filing.

Live Webcast on May 6, 2020; 2020 guidance slides posted on company website

ALLETE’s earnings conference call will be at 10:00 a.m. (EST), May 6, 2020, at which time management will discuss the first quarter of 2020 financial results and 2020 earnings guidance. Interested parties may listen live by calling 877-303-5852, pass code 7062128, ten minutes prior to the start time, or may listen to the live audio-only webcast accompanied by guidance slides, which will be available on ALLETE’s Investor Relations website http://investor.allete.com/events-presentations. A replay of the call will be available through May 11, 2020 by calling (855) 859-2056, pass code 7062128. The webcast will be accessible for one year at www.allete.com.

ALLETE is an energy company headquartered in Duluth, Minn. In addition to its electric utilities, Minnesota Power and Superior Water, Light and Power of Wisconsin, ALLETE owns ALLETE Clean Energy, based in Duluth, BNI Energy in Bismarck, N.D., and has an eight percent equity interest in the American Transmission Co.

The statements contained in this release and statements that ALLETE may make orally in connection with this release that are not historical facts, are forward-looking statements. Actual results may differ materially from those projected in the forward-looking statements. These forward-looking statements involve risks and uncertainties and investors are directed to the risks discussed in documents filed by ALLETE with the Securities and Exchange Commission.

ALLETE's press releases and other communications may include certain non-Generally Accepted Accounting Principles (GAAP) financial measures. A "non-GAAP financial measure" is defined as a numerical measure of a company's financial performance, financial position or cash flows that excludes (or includes) amounts that are included in (or excluded from) the most directly comparable measure calculated and presented in accordance with GAAP in the company's financial statements.

Non-GAAP financial measures utilized by the Company include presentations of earnings (loss) per share. ALLETE's management believes that these non-GAAP financial measures provide useful information to investors by removing the effect of variances in GAAP reported results of operations that are not indicative of changes in the fundamental earnings power of the Company's operations. Management believes that the presentation of the non-GAAP financial measures is appropriate and enables investors and analysts to more accurately compare the company's ongoing financial performance over the periods presented.

[1] For each of the three months ended March 31, 2020, and 2019, the federal and state current tax expense was minimal due to NOLs which resulted from the bonus depreciation provisions of the Protecting Americans from Tax Hikes Act of 2015, the Tax Increase Prevention Act of 2014 and the American Taxpayer Relief Act of 2012. Federal and state NOLs are being carried forward to offset current and future taxable income.

[2] For each of the three months ended March 31, 2020, and 2019, the federal income tax benefit is primarily due to production tax credits.

[3] For the three months ended March 31, 2019, the state income tax expense is primarily related to the sale of U.S. Water Services.

Fair Value Disclosures [Abstract]

Fair Value [Text Block]

FAIR VALUE

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). We utilize market data or assumptions that market participants would use in pricing the asset or liability, including assumptions about risk and the risks inherent in the inputs to the valuation technique. These inputs can be readily observable, market corroborated or generally unobservable. We primarily apply the market approach for recurring fair value measurements and endeavor to utilize the best available information. Accordingly, we utilize valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. These inputs, which are used to measure fair value, are prioritized through the fair value hierarchy. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurement) and the lowest priority to unobservable inputs (Level 3 measurement). Descriptions of the three levels of the fair value hierarchy are discussed in Note 7. Fair Value to the Consolidated Financial Statements in our 2019 Form 10-K.

The following tables set forth, by level within the fair value hierarchy, our assets and liabilities that were accounted for at fair value on a recurring basis as of March 31, 2020, and December 31, 2019. Each asset and liability is classified based on the lowest level of input that is significant to the fair value measurement. Our assessment of the significance of a particular input to the fair value measurement requires judgment, which may affect the valuation of these assets and liabilities and their placement within the fair value hierarchy levels. The estimated fair value of Cash and Cash Equivalents listed on the Consolidated Balance Sheet approximates the carrying amount and therefore is excluded from the recurring fair value measures in the following tables.

(c) Included in Other Non-Current Liabilities on the Consolidated Balance Sheet.

Fair Value of Financial Instruments. With the exception of the item listed in the following table, the estimated fair value of all financial instruments approximates the carrying amount. The fair value of the item listed in the following table was based on quoted market prices for the same or similar instruments (Level 2).

March 31, 2020	$1,731.3	$1,880.2
December 31, 2019	$1,622.6	$1,791.8

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis. Non-financial assets such as equity method investments, land inventory, and property, plant and equipment are measured at fair value when there is an indicator of impairment and recorded at fair value only when an impairment is recognized. For the three months ended March 31, 2020, and the year ended December 31, 2019, there were no indicators of impairment for these non-financial assets.

(a) For each of the three months ended March 31, 2020, and 2019, the federal and state current tax expense was minimal due to NOLs which resulted from the bonus depreciation provisions of the Protecting Americans from Tax Hikes Act of 2015, the Tax Increase Prevention Act of 2014 and the American Taxpayer Relief Act of 2012. Federal and state NOLs are being carried forward to offset current and future taxable income.

(b) For each of the three months ended March 31, 2020, and 2019, the federal income tax benefit is primarily due to production tax credits.

(c) For the three months ended March 31, 2019, the state income tax expense is primarily related to the sale of U.S. Water Services.

The Company's tax provision for interim periods is determined using an estimate of its annual effective tax rate, adjusted for discrete items arising in that quarter. In each quarter, the Company updates its estimate of the annual effective tax rate and if the estimated annual effective tax rate changes, the Company would make a cumulative adjustment in that quarter.

For the three months ended March 31, 2020, the effective tax rate was a benefit of 27.2 percent (expense of 4.0 percent for the three months ended March 31, 2019). The effective tax rate for 2020 was primarily impacted by production tax credits. The effective tax rate for 2019 was primarily impacted by production tax credits and the gain on sale of U.S. Water Services.

Uncertain Tax Positions. As of March 31, 2020, we had gross unrecognized tax benefits of $1.4 million ($1.4 million as of December 31, 2019). Of the total gross unrecognized tax benefits, $0.6 million represents the amount of unrecognized tax benefits included on the Consolidated Balance Sheet that, if recognized, would favorably impact the effective income tax rate. The unrecognized tax benefit amounts have been presented as reductions to the tax benefits associated with NOL and tax credit carryforwards on the Consolidated Balance Sheet.

We had $66.3 million outstanding in standby letters of credit and $0.2 million in outstanding draws under our lines of credit as of March 31, 2020 ($62.0 million in standby letters of credit and no outstanding draws as of December 31, 2019).

On January 10, 2020, ALLETE entered into a $200 million unsecured term loan agreement (Term Loan) of which we have borrowed $110 million as of March 31, 2020. The Term Loan provides for the ability to borrow up to an additional $90 million, is due on February 10, 2021, and may be repaid at any time. Interest is payable monthly at a rate per annum equal to LIBOR plus 0.55 percent. Proceeds from the Term Loan will be used for construction-related expenditures.

On March 26, 2020, ALLETE agreed to sell first mortgage bonds (Bonds) to certain institutional buyers in the private placement market, which will be issued on or before August 3, 2020, in two series as follows:

Maturity Date	Principal Amount	Interest Rate
August 1, 2030	$46 Million	2.50%
August 1, 2050	$94 Million	3.30%

ALLETE will have the option to prepay all or a portion of the Bonds at its discretion, subject to a make-whole provision. The Bonds will be subject to additional terms and conditions which are customary for these types of transactions. ALLETE plans to use the proceeds from the sale of the Bonds to fund utility capital investment and for general corporate purposes. The Bonds will be sold in reliance on an exemption from registration under Section 4(a)(2) of the Securities Act of 1933, as amended, to institutional accredited investors.

On April 8, 2020, ALLETE entered into a $115 million unsecured term loan agreement (Term Loan) and borrowed $95 million upon execution. The Term Loan provides for an additional draw of $20 million on or after July 1, 2020. The Term Loan is due on April 7, 2021, and may be repaid at any time. Interest is payable monthly at a rate per annum equal to LIBOR plus 1.7 percent with a LIBOR floor of 0.75 percent. Proceeds from the Term Loan will be used for general corporate purposes.

Financial Covenants. Our long-term debt arrangements contain customary covenants. In addition, our lines of credit and letters of credit supporting certain long-term debt arrangements contain financial covenants. Our compliance with financial covenants is not dependent on debt ratings. The most restrictive financial covenant requires ALLETE to maintain a ratio of indebtedness to total capitalization (as the amounts are calculated in accordance with the respective long-term debt arrangements) of less than or equal to 0.65 to 1.00, measured quarterly. As of March 31, 2020, our ratio was approximately 0.43 to 1.00. Failure to meet this covenant would give rise to an event of default if not cured after notice from the lender, in which event ALLETE may need to pursue alternative sources of funding. Some of ALLETE’s debt arrangements contain “cross-default” provisions that would result in an event of default if there is a failure under other financing arrangements to meet payment terms or to observe other covenants that would result in an acceleration of payments due. ALLETE has no significant restrictions on its ability to pay dividends from retained earnings or net income. As of March 31, 2020, ALLETE was in compliance with its financial covenants.

Operations and Significant Accounting Policies (Policies)

3 Months Ended

Mar. 31, 2020

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Cash and Cash Equivalents, Policy [Policy Text Block]

We consider all investments purchased with original maturities of three months or less to be cash equivalents.

Inventories – Net [Policy Text Block]

Inventories are stated at the lower of cost or net realizable value. Inventories in our Regulated Operations segment are carried at an average cost or first-in, first-out basis. Inventories in our ALLETE Clean Energy segment and Corporate and Other businesses are carried at an average cost, first-in, first-out or specific identification basis.

New Accounting Standards [Policy Text Block]

New Accounting Pronouncements.

Credit Losses. In 2016, the FASB issued an accounting standard update that requires entities to recognize an allowance for expected credit losses for financial instruments within its scope. Examples of financial instruments within the scope include trade receivables, certain financial guarantees, and held-to-maturity debt securities. The allowance for expected credit losses should be based on historical information, current conditions and reasonable and supportable forecasts. The new standard also revises the other-than-temporary impairment model for available-for-sale debt securities. The new guidance became effective January 1, 2020, and was adopted by the Company in the first quarter of 2020. Adoption of this standard did not have a material impact on our Consolidated Financial Statements.

Regulatory Assets and Liabilities [Policy Text Block]

With the exception of the regulatory asset for Boswell Units 1 and 2 net plant and equipment, no other regulatory assets are currently earning a return. The recovery, refund or credit to rates for these regulatory assets and liabilities will occur over the periods either specified by the applicable regulatory authority or over the corresponding period related to the asset or liability.

Equity Method Investments [Policy Text Block]

We account for our investment in Nobles 2 under the equity method of accounting.We account for our investment in ATC under the equity method of accounting.

Fair Value Measurement [Policy Text Block]

We utilize market data or assumptions that market participants would use in pricing the asset or liability, including assumptions about risk and the risks inherent in the inputs to the valuation technique. These inputs can be readily observable, market corroborated or generally unobservable. We primarily apply the market approach for recurring fair value measurements and endeavor to utilize the best available information. Accordingly, we utilize valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. These inputs, which are used to measure fair value, are prioritized through the fair value hierarchy. Each asset and liability is classified based on the lowest level of input that is significant to the fair value measurement. Our assessment of the significance of a particular input to the fair value measurement requires judgment, which may affect the valuation of these assets and liabilities and their placement within the fair value hierarchy levels.Non-financial assets such as equity method investments, land inventory, and property, plant and equipment are measured at fair value when there is an indicator of impairment and recorded at fair value only when an impairment is recognized.

Power Purchase Agreements [Policy Text Block]

Our long-term PPAs have been evaluated under the accounting guidance for variable interest entities. We have determined that either we have no variable interest in the PPAs or, where we do have variable interests, we are not the primary beneficiary; therefore, consolidation is not required. These conclusions are based on the fact that we do not have both control over activities that are most significant to the entity and an obligation to absorb losses or receive benefits from the entity’s performance. Our financial exposure relating to these PPAs is limited to our capacity and energy payments.

Environmental Accruals [Policy Text Block]

We review environmental matters on a quarterly basis. Accruals for environmental matters are recorded when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated based on current law and existing technologies. Accruals are adjusted as assessment and remediation efforts progress, or as additional technical or legal information becomes available. Accruals for environmental liabilities are included in the Consolidated Balance Sheet at undiscounted amounts and exclude claims for recoveries from insurance or other third parties. Costs related to environmental contamination treatment and cleanup are expensed unless recoverable in rates from customers.

Earnings Per Share [Policy Text Block]

We compute basic earnings per share using the weighted average number of shares of common stock outstanding during each period. The difference between basic and diluted earnings per share, if any, arises from non-vested restricted stock units and performance share awards granted under our Executive Long-Term Incentive Compensation Plan.

Income Tax [Policy Text Block]

The Company's tax provision for interim periods is determined using an estimate of its annual effective tax rate, adjusted for discrete items arising in that quarter. In each quarter, the Company updates its estimate of the annual effective tax rate and if the estimated annual effective tax rate changes, the Company would make a cumulative adjustment in that quarter.

Uncertain Tax Positions [Policy Text Block]

The unrecognized tax benefit amounts have been presented as reductions to the tax benefits associated with NOL and tax credit carryforwards on the Consolidated Balance Sheet.

Business Segments [Policy Text Block]

We present three reportable segments: Regulated Operations, ALLETE Clean Energy and U.S. Water Services. We measure performance of our operations through budgeting and monitoring of contributions to consolidated net income by each business segment.

ALLETE Clean Energy Asset Acquisition. On March 10, 2020, ALLETE Clean Energy acquired the rights to the Caddo wind project in Oklahoma from Apex Clean Energy for approximately $8 million with additional payments required to be made at defined milestones. The full development of this approximately 300 MW wind project would involve the sale of energy to corporate customers under long-term power sales agreements.

Non-Controlling Interest in Subsidiaries. Non-controlling interest in subsidiaries on the Consolidated Balance Sheet and net loss attributable to non-controlling interest on the Consolidated Statement of Income represent the portion of equity ownership and earnings, respectively, of subsidiaries that are not attributable to equity holders of ALLETE. These amounts as of and during the three months ended March 31, 2020, related to the tax equity financing structure for ALLETE Clean Energy’s 106 MW Glen Ullin wind energy facility.

On April 16, 2020, ALLETE Clean Energy commenced operations of South Peak, an 80 MW wind energy facility in Montana, and on April 29, 2020, received approximately $70 million in cash from a third-party investor as part of a tax equity financing for the wind energy facility.

BUSINESS SEGMENTS

We present three reportable segments: Regulated Operations, ALLETE Clean Energy and U.S. Water Services. We measure performance of our operations through budgeting and monitoring of contributions to consolidated net income by each business segment.

Regulated Operations includes three operating segments which consist of our regulated utilities, Minnesota Power and SWL&P, as well as our investment in ATC. ALLETE Clean Energy is our business focused on developing, acquiring and operating clean and renewable energy projects.

REGULATORY MATTERS

Regulatory matters are summarized in Note 4. Regulatory Matters to the Consolidated Financial Statements in our 2019 Form 10‑K, with additional disclosure provided in the following paragraphs.

Electric Rates. Entities within our Regulated Operations segment file for periodic rate revisions with the MPUC, PSCW or FERC. As authorized by the MPUC, Minnesota Power also recognizes revenue under cost recovery riders for transmission, renewable, and environmental investments and expenditures. Revenue from cost recovery riders was $9.6 million for the three months ended March 31, 2020 ($7.4 million for three months ended March 31, 2019).

2020 Minnesota General Rate Case. On November 1, 2019, Minnesota Power filed a retail rate increase request with the MPUC seeking an average increase of approximately 10.6 percent for retail customers. The rate filing seeks a return on equity of 10.05 percent and a 53.81 percent equity ratio. On an annualized basis, the requested final rate increase would generate approximately $66 million in additional revenue. In orders dated December 23, 2019, the MPUC accepted the filing as complete and authorized an annual interim rate increase of $36.1 million that began January 1, 2020. We cannot predict the level of final rates that may be authorized by the MPUC.

On April 23, 2020, Minnesota Power filed a request with the MPUC that proposes a resolution for Minnesota Power’s 2020 general rate case. Key components of our proposal include removing the current power marketing margin credit in base rates and reflecting actual power marketing margins in the fuel adjustment clause effective May 1, 2020; refunding to customers interim rates collected through April 2020 of approximately $12 million ($9 million as of March 31, 2020,); increasing ongoing customer rates 4.1 percent compared to the 5.8 percent increase reflected in current interim rates; and a provision that Minnesota Power would not file another rate case until at least March 1, 2021, unless certain events occur. Minnesota Power would withdraw its general rate case upon approval of this filing and proposed resolution by the MPUC. At a hearing on April 30, 2020, the MPUC approved lowering current interim rates to 4.1 percent effective May 1, 2020, as requested by Minnesota Power in this filing. A final decision on Minnesota Power’s full proposal in this filing is expected in June 2020. At this time, we are unable to predict whether the MPUC will ultimately approve this filing and proposed resolution, and thus, as of March 31, 2020, we have not recorded reserves for interim rates.

NOTE 2. REGULATORY MATTERS (Continued)

Electric Rates (Continued)

Transmission Cost Recovery Rider. Minnesota Power has an approved cost recovery rider in place for certain transmission investments and expenditures. In a 2016 order, the MPUC approved Minnesota Power’s updated customer billing rates allowing Minnesota Power to charge retail customers on a current basis for the costs of constructing certain transmission facilities plus a return on the capital invested. On July 9, 2019, Minnesota Power filed a petition seeking MPUC approval to update the customer billing factor to include investments made for the GNTL. (See Note 6. Commitments, Guarantees and Contingencies.)

Renewable Cost Recovery Rider. Minnesota Power has an approved cost recovery rider for certain renewable investments and expenditures. The cost recovery rider allows Minnesota Power to charge retail customers on a current basis for the costs of certain renewable investments plus a return on the capital invested. Current customer billing rates for the renewable cost recovery rider were approved by the MPUC in a November 2018 order. On August 15, 2019, Minnesota Power filed a petition seeking MPUC approval to update the customer billing factor.

Fuel Adjustment Clause Reform. In a 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. 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 May 1, 2019, Minnesota Power filed its fuel adjustment forecast for 2020, which was accepted by the MPUC in an order dated November 14, 2019, for purposes of setting fuel adjustment clause rates for 2020, subject to a true-up filing in 2021.

COVID-19 Related Costs. In an order dated March 24, 2020, the PSCW authorized public utilities, which includes SWL&P, to defer expenditures incurred by the utility resulting from its compliance with state government or regulator orders, and as otherwise required to ensure the provision of safe, reliable and affordable access to utility services during Wisconsin’s declared public health emergency for COVID-19. On April 20, 2020, Minnesota Power along with other regulated electric and natural gas service providers in Minnesota filed a joint petition to request MPUC authorization to track incremental costs and expenses incurred as a result of COVID-19, and to defer and record such costs as a regulatory asset, subject to recovery in a future proceeding. 

Integrated Resource Plan. In a 2016 order, the MPUC approved Minnesota Power’s 2015 IRP with modifications. The order accepted Minnesota Power’s plans for the economic idling of Taconite Harbor Units 1 and 2 and the ceasing of coal-fired operations at Taconite Harbor in 2020, directed Minnesota Power to retire Boswell Units 1 and 2 no later than 2022, required an analysis of generation and demand response alternatives to be filed with a natural gas resource proposal, and required Minnesota Power to conduct requests for proposal for additional wind, solar and demand response resource additions. Minnesota Power retired Boswell Units 1 and 2 in the fourth quarter of 2018. Minnesota Power’s next IRP filing is due October 1, 2020.

Nemadji Trail Energy Center. In 2017, Minnesota Power submitted a resource package to the MPUC which included requesting approval of a 250 MW natural gas capacity dedication agreement. The natural gas capacity dedication agreement was subject to MPUC approval of the construction of NTEC, a 525 MW to 550 MW combined-cycle natural gas‑fired generating facility which will be jointly owned by Dairyland Power Cooperative and a subsidiary of ALLETE. Minnesota Power would purchase approximately 50 percent of the facility's output starting in 2025. In an order dated January 24, 2019, the MPUC approved Minnesota Power’s request for approval of the NTEC natural gas capacity dedication agreement. Separately, the MPUC required a baseload retirement evaluation in Minnesota Power’s next IRP filing analyzing its existing fleet, including potential early retirement scenarios of Boswell Units 3 and 4, as well as a securitization plan. On December 23, 2019, the Minnesota Court of Appeals reversed and remanded the MPUC’s decision to approve certain affiliated-interest agreements. The MPUC was ordered to determine whether NTEC may have the potential for significant environmental effects and, if so, to prepare an environmental assessment worksheet before reassessing the agreements. On January 22, 2020, Minnesota Power filed a petition for further review with the Minnesota Supreme Court requesting that it review and overturn the Minnesota Court of Appeals decision, which petition was accepted for review by the Minnesota Supreme Court on March 18, 2020. On January 8, 2019, an application for a certificate of public convenience and necessity for NTEC was submitted to the PSCW, which was approved by the PSCW at a hearing on January 16, 2020. Construction of NTEC is subject to obtaining additional permits from local, state and federal authorities. The total project cost is estimated to be approximately $700 million, of which ALLETE’s portion is expected to be approximately $350 million. ALLETE’s portion of NTEC project costs incurred through March 31, 2020, is approximately $13 million.

MISO Return on Equity Complaint. MISO transmission owners, including ALLETE and ATC, have an authorized return on equity of 9.88 percent, or 10.38 percent including an incentive adder for participation in a regional transmission organization, based on a November 2019 FERC order. In this order, the FERC reduced the base return on equity for regional transmission organizations as recommended by an administrative law judge with refunds ordered for prior periods, which are immaterial to ALLETE. Multiple parties to the complaint have filed requests for rehearing of the FERC order.

NOTE 2. REGULATORY MATTERS (Continued)

Regulatory Assets and Liabilities. Our regulated utility operations are subject to accounting guidance for the effect of certain types of regulation. Regulatory assets represent incurred costs that have been deferred as they are probable for recovery in customer rates. Regulatory liabilities represent obligations to make refunds to customers and amounts collected in rates for which the related costs have not yet been incurred. The Company assesses quarterly whether regulatory assets and liabilities meet the criteria for probability of future recovery or deferral. With the exception of the regulatory asset for Boswell Units 1 and 2 net plant and equipment, no other regulatory assets are currently earning a return. The recovery, refund or credit to rates for these regulatory assets and liabilities will occur over the periods either specified by the applicable regulatory authority or over the corresponding period related to the asset or liability.

Commitments and Contingencies Disclosure [Abstract]

Commitments, Guarantees and Contingencies [Text Block]

COMMITMENTS, GUARANTEES AND CONTINGENCIES

Power Purchase and Sale Agreements. Our long-term PPAs have been evaluated under the accounting guidance for variable interest entities. We have determined that either we have no variable interest in the PPAs or, where we do have variable interests, we are not the primary beneficiary; therefore, consolidation is not required. These conclusions are based on the fact that we do not have both control over activities that are most significant to the entity and an obligation to absorb losses or receive benefits from the entity’s performance. Our financial exposure relating to these PPAs is limited to our capacity and energy payments.

Our PPAs are summarized in Note 9. Commitments, Guarantees and Contingencies to the Consolidated Financial Statements in our 2019 Form 10-K, with additional disclosure provided in the following paragraphs.

Square Butte PPA. As of March 31, 2020, Square Butte had total debt outstanding of $276.2 million. Fuel expenses are recoverable through Minnesota Power’s fuel adjustment clause and include the cost of coal purchased from BNI Energy under a long-term contract. Minnesota Power’s cost of power purchased from Square Butte during the three months ended March 31, 2020, was $20.1 million ($20.5 million for the same period in 2019). This reflects Minnesota Power’s pro rata share of total Square Butte costs based on the 50 percent output entitlement. Included in this amount was Minnesota Power’s pro rata share of interest expense of $1.9 million ($2.1 million for the same period in 2019). Minnesota Power’s payments to Square Butte are approved as a purchased power expense for ratemaking purposes by both the MPUC and the FERC.

Minnkota Power PSA. Minnesota Power has a PSA with Minnkota Power, which commenced in 2014. Under the PSA, Minnesota Power is selling a portion of its entitlement from Square Butte to Minnkota Power, resulting in Minnkota Power’s net entitlement increasing and Minnesota Power’s net entitlement decreasing until Minnesota Power’s share is eliminated at the end of 2025. Of Minnesota Power’s 50 percent output entitlement, it sold to Minnkota Power approximately 28 percent in 2020 and in 2019.

Minnesota Power Short-term PSAs. Minnesota Power has entered into various short-term PSAs to sell 300 MW of energy in 2020 and 2021. These PSAs were entered into to proactively mitigate the uncertainty of customers’ energy needs and potential load loss due to the COVID-19 pandemic. Additional transactions, purchases or sales, could be entered into as the extent and duration of the COVID-19 pandemic becomes known.

Coal, Rail and Shipping Contracts. Minnesota Power has coal supply agreements providing for the purchase of a significant portion of its coal requirements through December 2021. Minnesota Power also has coal transportation agreements in place for the delivery of a significant portion of its coal requirements through December 2021. The costs of fuel and related transportation costs for Minnesota Power’s generation are recoverable from Minnesota Power’s utility customers through the fuel adjustment clause.

Transmission. We continue to make investments in transmission opportunities that strengthen or enhance the transmission grid or take advantage of our geographical location between sources of renewable energy and end users. These include the GNTL, investments to enhance our own transmission facilities, investments in other transmission assets (individually or in combination with others) and our investment in ATC.

Great Northern Transmission Line. As a condition of the 250-MW long-term PPA entered into with Manitoba Hydro, construction of additional transmission capacity is required. As a result, Minnesota Power is constructing the GNTL, an approximately 220‑mile 500-kV transmission line between Manitoba and Minnesota’s Iron Range that was proposed by Minnesota Power and Manitoba Hydro in order to strengthen the electric grid, enhance regional reliability and promote a greater exchange of sustainable energy.

In a 2016 order, the MPUC approved the route permit for the GNTL, and in 2016, the U.S. Department of Energy issued a presidential permit to cross the U.S.-Canadian border, which was the final major regulatory approval needed before construction in the U.S. could begin. Construction activities commenced in the first quarter of 2017, and Minnesota Power expects the GNTL to be in-service by mid-2020. The total project cost in the U.S., including substation work, is estimated to be approximately $700 million, of which Minnesota Power’s portion is expected to be approximately $325 million; the difference will be recovered from a subsidiary of Manitoba Hydro as non-shareholder contributions to capital. Total project costs of $647.7 million have been incurred through March 31, 2020, of which $344.6 million has been recovered from a subsidiary of Manitoba Hydro.

In June 2019, Manitoba Hydro announced the Canadian federal government’s approval of the MMTP project and in August 2019, the Canadian National Energy Board granted final pre-construction approvals. Construction on the MMTP commenced in the third quarter of 2019. On April 16, 2020, Manitoba Hydro announced that construction of the MMTP was complete and that testing and commissioning of the line, communications equipment and substation will take place to meet the anticipated in-service deadline of June 1, 2020. The MMTP is still subject to legal challenges which Minnesota Power is actively monitoring.

NOTE 6. COMMITMENTS, GUARANTEES AND CONTINGENCIES (Continued)

Transmission (Continued)

Construction of Manitoba Hydro’s Keeyask hydroelectric generation facility, which will provide the power to be sold under PPAs with Minnesota Power and transmitted on the MMTP and the GNTL, commenced in 2014 and is anticipated to be completely in-service by early 2021.

Environmental Matters.

Our businesses are subject to regulation of environmental matters by various federal, state and local authorities. A number of regulatory changes to the Clean Air Act, the Clean Water Act and various waste management requirements have been promulgated by both the EPA and state authorities over the past several years. Minnesota Power’s facilities are subject to additional requirements under many of these regulations. Minnesota Power is reshaping its generation portfolio, over time, to reduce its reliance on coal, has installed cost-effective emission control technology, and advocates for sound science and policy during rulemaking implementation.

We consider our businesses to be in substantial compliance with currently applicable environmental regulations and believe all necessary permits have been obtained. We anticipate that with many state and federal environmental regulations and requirements finalized, or to be finalized in the near future, potential expenditures for future environmental matters may be material and require significant capital investments. Minnesota Power has evaluated various environmental compliance scenarios using possible outcomes of environmental regulations to project power supply trends and impacts on customers.

We review environmental matters on a quarterly basis. Accruals for environmental matters are recorded when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated based on current law and existing technologies. Accruals are adjusted as assessment and remediation efforts progress, or as additional technical or legal information becomes available. Accruals for environmental liabilities are included in the Consolidated Balance Sheet at undiscounted amounts and exclude claims for recoveries from insurance or other third parties. Costs related to environmental contamination treatment and cleanup are expensed unless recoverable in rates from customers.

Air. The electric utility industry is regulated both at the federal and state level to address air emissions. Minnesota Power’s generating facilities mainly burn low-sulfur western sub-bituminous coal. All of Minnesota Power’s coal-fired generating facilities are equipped with pollution control equipment such as scrubbers, baghouses and low NO_X technologies. Under currently applicable environmental regulations, these facilities are substantially compliant with emission requirements.

Cross-State Air Pollution Rule (CSAPR). The CSAPR requires certain states in the eastern half of the U.S., including Minnesota, to reduce power plant emissions that contribute to ozone or fine particulate pollution in other states. The CSAPR does not require installation of controls but does require facilities have sufficient allowances to cover their emissions on an annual basis. These allowances are allocated to facilities from each state’s annual budget, and can be bought and sold. Based on our review of the NO_x and SO₂ allowances issued and pending issuance, we currently expect generation levels and emission rates will result in continued compliance with the CSAPR.

National Ambient Air Quality Standards (NAAQS). The EPA is required to review the NAAQS every five years. If the EPA determines that a state’s air quality is not in compliance with the NAAQS, the state is required to adopt plans describing how it will reduce emissions to attain the NAAQS. None of the compliance costs for proposed or current NAAQS revisions are expected to be material.

NOTE 6. COMMITMENTS, GUARANTEES AND CONTINGENCIES (Continued)

Environmental Matters (Continued)

Climate Change. The scientific community generally accepts that emissions of GHG are linked to global climate change which creates physical and financial risks. Physical risks could include, but are not limited to: increased or decreased precipitation and water levels in lakes and rivers; increased temperatures; and changes in the intensity and frequency of extreme weather events. These all have the potential to affect the Company’s business and operations. We are addressing climate change by taking the following steps that also ensure reliable and environmentally compliant generation resources to meet our customers’ requirements:

• Expanding renewable power supply for both our operations and the operations of others;

• Providing energy conservation initiatives for our customers and engaging in other demand side management efforts;

• Improving efficiency of our generating facilities;

• Supporting research of technologies to reduce carbon emissions from generating facilities and carbon sequestration efforts;

• Evaluating and developing less carbon intensive future generating assets such as efficient and flexible natural gas-fired generating facilities;

• Managing vegetation on right-of-way corridors to reduce potential wildfire or storm damage risks; and

• Practicing sound forestry management in our service territories to create landscapes more resilient to disruption from climate-related changes, including planting and managing long-lived conifer species.

EPA Regulation of GHG Emissions. On June 19, 2019, the EPA finalized several separate rulemakings regarding regulating carbon emissions from electric utility generating units.

The EPA repealed the Clean Power Plan (CPP), following a determination by the EPA that the CPP exceeded the EPA’s statutory authority under the Clean Air Act (CAA). The primary reason for this was that the CPP attempted to regulate electric generating unit’s carbon emissions through measures outside of the affected unit’s direct control. The CPP was first announced as a proposed rule under Section 111(d) of the Clean Air Act for existing power plants entitled “Carbon Pollution Emission Guidelines for Existing Stationary Sources: Electric Generating Units”.

With the repeal of the CPP, the Affordable Clean Energy Rule was finalized. The rule establishes emissions guidelines for states to use when developing plans to limit carbon dioxide at coal-fired power plants. The rule identifies heat rate improvements made at individual units as the best system of emission reduction. Affected facilities for Minnesota Power include Boswell Units 3 and 4. Based on our initial review of the rule, many of the candidate heat rate improvements are already installed on Boswell Units 3 and 4 and the currently economically idled Taconite Harbor 1 and 2.

Additionally, the EPA finalized new regulations for the state implementation of the Affordable Clean Energy Rule and any future emission guidelines issued under CAA Section 111(d). States will have three years to submit State Implementation Plans (SIPs), and the EPA has 12 months to review and approve those plans. Since the Affordable Clean Energy Rule allows states considerable flexibility in how to best implement its requirements, Minnesota Power plans to work closely with the MPCA and the Minnesota Department of Commerce, who are currently co-reviewing the rule as the state develops its SIP. If a state does not submit a SIP or submits a SIP that is unacceptable to the EPA, the EPA will develop a Federal Implementation Plan. The MPCA currently plans to develop a SIP for the Affordable Clean Energy Rule.

Minnesota had already initiated several measures consistent with those called for under the now repealed CPP and finalized Affordable Clean Energy Rule. Minnesota Power continues implementing its EnergyForward strategic plan that provides for significant emission reductions and diversifying its electricity generation mix to include more renewable and natural gas energy. (See Note 2. Regulatory Matters.) We are unable to predict the GHG emission compliance costs we might incur as a result of the Affordable Clean Energy Rule and the resulting SIP; however, the costs could be material. Minnesota Power would seek recovery of additional costs through a rate proceeding.

Water. The Clean Water Act requires NPDES permits be obtained from the EPA (or, when delegated, from individual state pollution control agencies) for any wastewater discharged into navigable waters. We have obtained all necessary NPDES permits, including NPDES storm water permits for applicable facilities, to conduct our operations.

Environmental Matters (Continued)

Steam Electric Power Generating Effluent Limitations Guidelines. In 2015, the EPA issued revised federal effluent limitation guidelines (ELG) for steam electric power generating stations under the Clean Water Act. It set effluent limits and prescribed BACT for several wastewater streams, including flue gas desulphurization (FGD) water, bottom ash transport water and coal combustion landfill leachate. In 2017, the EPA announced a two-year postponement of the ELG compliance date of November 1, 2018, to November 1, 2020, while the agency reconsiders the bottom ash transport water and FGD wastewater provisions. On April 12, 2019, the U.S. Court of Appeals for the Fifth Circuit vacated and remanded back to the EPA portions of the ELG that allowed for continued discharge of legacy wastewater and leachate. On November 22, 2019, the EPA published a draft rulemaking that proposes to allow re-use of bottom ash transport water in FGD scrubber systems with minor discharges related to maintaining system water balance. The proposed rulemaking would also allow future discharge of FGD wastewater discharge provided it meets new BACT standards. A final rulemaking is anticipated in mid to late 2020.

The ELG's potential impact on Minnesota Power operations is primarily at Boswell. Boswell currently discharges bottom ash contact water through its NPDES permit, and also has a closed-loop FGD system that does not discharge to surface waters, but may do so in the future if additional water treatment measures are implemented. Under the current ELG rule, bottom ash transport water discharge to surface waters must cease no later than December 31, 2023. Bottom ash contact water will either need to be re-used in a closed-loop process, routed to a FGD scrubber, or the bottom ash handling system will need to be converted to a dry process. The ELG rule provision regarding these two waste-streams are being reconsidered and may change prior to November 1, 2020. Efforts have been underway at Boswell to reduce the amount of water discharged and evaluate potential re-use options in its plant processes. The EPA’s additional reconsideration of legacy wastewater discharge requirements have the potential to reduce time lines for dewatering Boswell’s existing bottom ash pond. The timing of a draft rule addressing legacy wastewater and leachate is currently unknown.

At this time, we cannot estimate what compliance costs we might incur related to these or other potential future water discharge regulations; however, the costs could be material, including costs associated with retrofits for bottom ash handling, pond dewatering, pond closure, and wastewater treatment and re-use. Minnesota Power would seek recovery of additional costs through a rate proceeding.

Solid and Hazardous Waste. The Resource Conservation and Recovery Act of 1976 regulates the management and disposal of solid and hazardous wastes. We are required to notify the EPA of hazardous waste activity and, consequently, routinely submit reports to the EPA.

Coal Ash Management Facilities. Minnesota Power stores or disposes coal ash at four of its electric generating facilities by the following methods: storing ash in clay-lined onsite impoundments (ash ponds), disposing of dry ash in a lined dry ash landfill, applying ash to land as an approved beneficial use and trucking ash to state permitted landfills.

Coal Combustion Residuals from Electric Utilities (CCR). In 2015, the EPA published the final rule regulating CCR as nonhazardous waste under Subtitle D of the Resource Conservation and Recovery Act (RCRA) in the Federal Register. The rule includes additional requirements for new landfill and impoundment construction as well as closure activities related to certain existing impoundments. Costs of compliance for Boswell and Laskin are expected to occur primarily over the next 15 years and be between approximately $65 million and $120 million. Compliance costs for CCR at Taconite Harbor are not expected to be material. Minnesota Power would seek recovery of additional costs through a rate proceeding.

Minnesota Power continues to work on minimizing costs through evaluation of beneficial re-use and recycling of CCR and CCR‑related waters. In 2017, the EPA announced its intention to formally reconsider the CCR rule under Subtitle D of the RCRA and in March 2018, published the first phase of the proposed rule revisions in the Federal Register. In July 2018, the EPA finalized revisions to elements of the CCR rule, including extending certain deadlines by two years, the establishment of alternative groundwater protection standards for certain constituents and the potential for risk-based management options at facilities based on site characteristics. In August 2018, a U.S. District Court for the District of Columbia decision vacated specific provisions of the CCR rule. The court decision changed the status of three existing impoundments at Boswell that must now be considered unlined. The EPA proposed additional rule revisions in August and December 2019 to address outstanding issues from litigation and closure timelines for unlined impoundments, respectively. These rules are anticipated to be finalized in 2020 and could impact the timing of closure activities for Boswell’s three impoundments. Additionally, the EPA recently released a proposed Part B rulemaking that addresses options for beneficial reuse of CCR materials, alternative liner demonstrations, and other CCR regulatory revisions. Compliance costs at Boswell due to the court decision are unknown at this time. Minnesota Power would seek recovery of additional costs through a rate proceeding.

Other Environmental Matters

Manufactured Gas Plant Site. We are reviewing and addressing environmental conditions at a former manufactured gas plant site located in Superior, Wisconsin. SWL&P has been working with the Wisconsin Department of Natural Resources (WDNR) in determining the extent of contamination at the site and surrounding properties. In December 2017, the WDNR authorized SWL&P to transition from site investigation into the remedial design process. As of March 31, 2020, we have recorded a liability of approximately $7 million for remediation costs at this site (approximately $7 million as of December 31, 2019). SWL&P has also recorded an associated regulatory asset as we expect recovery of these remediation costs to be allowed by the PSCW. Remediation costs are expected to be incurred through 2023.

Other Matters.

ALLETE Clean Energy. ALLETE Clean Energy’s wind energy facilities have PSAs in place for their entire output and expire in various years between 2022 and 2039. As of March 31, 2020, ALLETE Clean Energy has $59.6 million outstanding in standby letters of credit, the majority of which are held as security under these PSAs and PSAs for wind energy facilities under development.

BNI Energy. As of March 31, 2020, BNI Energy had surety bonds outstanding of $67.7 million related to the reclamation liability for closing costs associated with its mine and mine facilities. Although its coal supply agreements obligate the customers to provide for the closing costs, additional assurance is required by federal and state regulations.

Community Development District Obligations. As of March 31, 2020, we owned 53 percent of the assessable land in the Town Center District (53 percent as of December 31, 2019). As of March 31, 2020, ownership levels, our annual assessments related to capital improvement and special assessment bonds for the ALLETE Properties project within the district is approximately $1.9 million. As we sell property at this project, the obligation to pay special assessments will pass to the new landowners. In accordance with accounting guidance, these bonds are not reflected as debt on our Consolidated Balance Sheet.

Legal Proceedings.

We are involved in litigation arising in the normal course of business. Also in the normal course of business, we are involved in tax, regulatory and other governmental audits, inspections, investigations and other proceedings that involve state and federal taxes, safety, and compliance with regulations, rate base and cost of service issues, among other things. We do not expect the outcome of these matters to have a material effect on our financial position, results of operations or cash flows.

(a) For each of the three months ended March 31, 2020, and 2019, the federal and state current tax expense was minimal due to NOLs which resulted from the bonus depreciation provisions of the Protecting Americans from Tax Hikes Act of 2015, the Tax Increase Prevention Act of 2014 and the American Taxpayer Relief Act of 2012. Federal and state NOLs are being carried forward to offset current and future taxable income.

(b) For each of the three months ended March 31, 2020, and 2019, the federal income tax benefit is primarily due to production tax credits.

(c) For the three months ended March 31, 2019, the state income tax expense is primarily related to the sale of U.S. Water Services.
