CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING INFORMATION

In this report, we make statements concerning our expectations, beliefs, plans, objectives, goals, strategies, and future events or performance. These statements are "forward-looking statements" within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Exchange Act. Readers are cautioned not to place undue reliance on these forward-looking statements. Forward-looking statements may be identified by reference to a future period or periods or by the use of terms such as "anticipates," "believes," "could," "estimates," "expects," "forecasts," "goals," "guidance," "intends," "may," "objectives," "plans," "possible," "potential," "projects," "seeks," "should," "targets," "will," or variations of these terms.

Forward-looking statements include, among other things, statements concerning management's expectations and projections regarding earnings, completion of capital projects, sales and customer growth, rate actions and related filings with regulatory authorities, environmental and other regulations and associated compliance costs, legal proceedings, effective tax rates, pension and OPEB plans, fuel costs, sources of electric energy supply, coal and natural gas deliveries, remediation costs, environmental matters, liquidity and capital resources, and other matters.

Forward-looking statements are subject to a number of risks and uncertainties that could cause our actual results to differ materially from those expressed or implied in the statements. These risks and uncertainties include those described in risk factors as set forth in this report and our 2018 Annual Report on Form 10-K, and those identified below:

• Factors affecting utility operations such as catastrophic weather-related damage, environmental incidents, unplanned facility outages and repairs and maintenance, and electric transmission or natural gas pipeline system constraints;

• Factors affecting the demand for electricity and natural gas, including political developments, unusual weather, changes in economic conditions, customer growth and declines, commodity prices, energy conservation efforts, and continued adoption of distributed generation by customers;

• The timing, resolution, and impact of rate cases and negotiations, including recovery of deferred and current costs and the ability to earn a reasonable return on investment, and other regulatory decisions impacting our regulated operations;

• The ability to obtain and retain customers, including wholesale customers, due to increased competition in our electric and natural gas markets from retail choice and alternative electric suppliers, and continued industry consolidation;

• The timely completion of capital projects within budgets, as well as the recovery of the related costs through rates;

• The impact of federal, state, and local legislative and/or regulatory changes, including changes in rate-setting policies or procedures, deregulation and restructuring of the electric and/or natural gas utility industries, transmission or distribution system operation, the approval process for new construction, reliability standards, pipeline integrity and safety standards, allocation of energy assistance, energy efficiency mandates, and tax laws that affect our ability to use production tax credits and investment tax credits;

• The remaining uncertainty surrounding the Tax Legislation enacted in December 2017, including implementing regulations and IRS interpretations, the amount to be returned to our ratepayers, and its impact, if any, on our credit ratings;

• Federal and state legislative and regulatory changes relating to the environment, including climate change and other environmental regulations impacting generation facilities and renewable energy standards, the enforcement of these laws and regulations, changes in the interpretation of regulations or permit conditions by regulatory agencies, and the recovery of associated remediation and compliance costs;

• Factors affecting the implementation of WEC Energy Group's generation reshaping plan, including related regulatory decisions, the cost of materials, supplies, and labor, and the feasibility of competing projects;

• Increased pressure on WEC Energy Group and us by investors and other stakeholder groups to take more aggressive action to reduce future GHG emissions in order to limit future global temperature increases;

• The risks associated with changing commodity prices, particularly natural gas and electricity, and the availability of sources of fossil fuel, natural gas, purchased power, materials needed to operate environmental controls at our electric generating facilities,

06/30/2019 Form 10-Q 1 Wisconsin Public Service Corporation

or water supply due to high demand, shortages, transportation problems, nonperformance by electric energy or natural gas suppliers under existing power purchase or natural gas supply contracts, or other developments;

• Changes in credit ratings, interest rates, and our ability to access the capital markets, caused by volatility in the global credit markets, our capitalization structure, and market perceptions of the utility industry or us;

• Costs and effects of litigation, administrative proceedings, investigations, settlements, claims, and inquiries;

• The risk of financial loss, including increases in bad debt expense, associated with the inability of our customers, counterparties, and affiliates to meet their obligations;

• Changes in the creditworthiness of the counterparties with whom we have contractual arrangements, including participants in the energy trading markets and fuel suppliers and transporters;

• The direct or indirect effect on our business resulting from terrorist attacks and cyber security intrusions, as well as the threat of such incidents, including the failure to maintain the security of personally identifiable information, the associated costs to protect our utility assets, technology systems, and personal information, and the costs to notify affected persons to mitigate their information security concerns and to comply with state notification laws;

• The investment performance of our employee benefit plan assets, as well as unanticipated changes in related actuarial assumptions, which could impact future funding requirements;

• Factors affecting the employee workforce, including loss of key personnel, internal restructuring, work stoppages, and collective bargaining agreements and negotiations with union employees;

• Advances in technology, and related legislation or regulation supporting the use of that technology, that result in competitive disadvantages and create the potential for impairment of existing assets;

• Potential business strategies to acquire and dispose of assets or businesses, which cannot be assured to be completed timely, if at all, or within budgets;

• The timing and outcome of any audits, disputes, and other proceedings related to taxes;

• The ability to maintain effective internal controls in accordance with Section 404 of the Sarbanes-Oxley Act, while both integrating and continuing to consolidate WEC Energy Group's enterprise systems with those of its other utilities;

• The effect of accounting pronouncements issued periodically by standard-setting bodies; and

• Other considerations disclosed elsewhere herein and in other reports we file with the SEC or in other publicly disseminated written documents.

We expressly disclaim any obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events, or otherwise.

NOTES TO CONDENSED FINANCIAL STATEMENTS (Unaudited)

June 30, 2019

NOTE 1—GENERAL INFORMATION

Wisconsin Public Service Corporation serves approximately 447,000 electric customers and 330,800 natural gas customers.

As used in these notes, the term "financial statements" refers to the condensed financial statements. This includes the income statements, balance sheets, statements of cash flows, and statements of equity, unless otherwise noted. In this report, when we refer to "the Company," "us," "we," "our," or "ours," we are referring to Wisconsin Public Service Corporation.

We have prepared the unaudited interim financial statements presented in this Form 10-Q pursuant to the rules and regulations of the SEC and GAAP. Accordingly, these financial statements do not include all of the information and footnotes required by GAAP for annual financial statements. These financial statements should be read in conjunction with the consolidated financial statements and footnotes in our Annual Report on Form 10-K for the year ended December 31, 2018. Financial results for an interim period may not give a true indication of results for the year. In particular, the results of operations for the three and six months ended June 30, 2019 are not necessarily indicative of expected results for 2019 due to seasonal variations and other factors.

In management's opinion, we have included all adjustments, normal and recurring in nature, necessary for a fair presentation of our financial results.

NOTE 2—ACQUISITION

Acquisition of a Wind Energy Generation Facility in Wisconsin

In April 2018, we, along with two unaffiliated utilities, completed the purchase of Forward Wind Energy Center, which consists of 86 wind turbines located in Wisconsin with a total capacity of 138 MW. The aggregate purchase price was $172.9 million of which our proportionate share was 44.6%, or $77.1 million. In addition, we incurred transaction costs that are recorded to a regulatory asset. Since 2008 and up until the acquisition, we purchased 44.6% of the facility’s energy output under a power purchase agreement.

Under a joint ownership agreement with the two other utilities, we are entitled to our share of generating capability and output of the facility equal to our ownership interest. We are also paying our ownership share of additional capital expenditures and operating expenses. This acquisition was accounted for as an asset acquisition.

NOTE 3—OPERATING REVENUES

For more information about our significant accounting policies related to operating revenues, see Note 1(d), Operating Revenues, in our 2018 Annual Report on Form 10-K.

06/30/2019 Form 10-Q 7 Wisconsin Public Service Corporation

Disaggregation of Operating Revenues

The following tables present our operating revenues disaggregated by revenue source for our utility segment. We do not have any revenues associated with our other segment. We disaggregate revenues into categories that depict how the nature, amount, timing, and uncertainty of revenues and cash flows are affected by economic factors. For our utility segment, revenues are further disaggregated by electric and natural gas operations and then by customer class. Each customer class within our electric and natural gas operations have different expectations of service, energy and demand requirements, and are impacted by regulatory activities within their jurisdictions.

NOTE 5—COMMON EQUITY

Various financing arrangements and regulatory requirements impose certain restrictions on our ability to transfer funds to the sole holder of our common stock, Integrys, in the form of cash dividends, loans, or advances. In addition, Wisconsin law prohibits us from making loans to or guaranteeing obligations of WEC Energy Group, Integrys, or their subsidiaries. See Note 10, Common Equity, in our 2018 Annual Report on Form 10-K for additional information on these and other restrictions.

We do not believe that these restrictions will materially affect our operations or limit any dividend payments in the foreseeable future.

NOTE 7—LEASES

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which revised the previous guidance (Topic 840) regarding accounting for leases. Revisions include requiring a lessee to recognize a lease asset and a lease liability on its balance sheet for each lease, including operating leases with an initial term greater than 12 months. In addition, required quantitative and qualitative disclosures related to lease agreements were expanded.

As required, we adopted Topic 842 effective January 1, 2019. We utilized the following practical expedients, which were available under ASU 2016-02, in our adoption of the new lease guidance.

• We did not reassess whether any expired or existing contracts were leases or contained leases.

• We did not reassess the lease classification for any expired or existing leases.

• We did not reassess the accounting for initial direct costs for any existing leases.

We did not elect the practical expedient allowing entities to account for the nonlease components in lease contracts as part of the single lease component to which they were related. Instead, in accordance with Accounting Standards Codification 842-10-15-31, our policy is to account for each lease component separately from the nonlease components of the contract.

We did not elect the practical expedient to use hindsight in determining the lease term and in assessing impairment of our right of use assets. No impairment losses were included in the measurement of our right of use assets upon our adoption of Topic 842.

In January 2018, the FASB issued ASU 2018-01, Leases (Topic 842): Land Easement Practical Expedient for Transition to Topic 842, which is an amendment to ASU 2016-02. Land easements (also commonly referred to as rights of way) represent the right to use,

06/30/2019 Form 10-Q 10 Wisconsin Public Service Corporation

access or cross another entity's land for a specified purpose. This new guidance permits an entity to elect a transitional practical expedient, to be applied consistently, to not evaluate under Topic 842 land easements that were already in existence or had expired at the time of the entity's adoption of Topic 842. Once Topic 842 is adopted, an entity is required to apply Topic 842 prospectively to all new (or modified) land easements to determine whether the arrangement should be accounted for as a lease. We elected this practical expedient, resulting in none of our land easements being treated as leases upon our adoption of Topic 842.

In July 2018, the FASB issued ASU 2018-11, Leases (Topic 842): Targeted Improvements, which amends ASU 2016-02 and allows entities the option to initially apply Topic 842 at the adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption, if required. We used the optional transition method to apply the new guidance as of January 1, 2019, rather than as of the earliest period presented. We documented our technical accounting issues, implemented required changes to internal controls and processes, and identified no significant operating or finance leases as a result of our implementation of the new lease guidance. As a result, the adoption of Topic 842 did not result in us recording any right of use assets or related lease liabilities related to operating leases, and we had no finance leases upon adoption.

Significant Judgments and Other Information

We are currently party to several easement agreements that allow us access to land we do not own for the purpose of constructing and maintaining certain electric power and natural gas equipment. The majority of payments we make related to easements relate to our wind farms. We have not classified our easements as leases because we view the entire parcel of land specified in our easement agreements to be the identified asset, not just that portion of the parcel that contains our easement. As such, we have concluded that we do not control the use of an identified asset related to our easement agreements, nor do we obtain substantially all of the economic benefits associated with these shared-use assets.

Related to our investment in the Two Creeks Solar Project, we, along with an unaffiliated utility, entered into several land leases in Manitowoc County, Wisconsin that commenced in the third quarter of 2019. The leases are for a total of approximately 900 acres of land and each has an initial term of 30 years with two optional 10-year extensions.

NOTE 8—MATERIALS, SUPPLIES, AND INVENTORIES

Our inventory consisted of:

(in millions)	June 30, 2019		December 31, 2018
Materials and supplies	$	52.3	$	48.9
Fossil fuel	34.9		29.2

Substantially all materials and supplies, fossil fuel, and natural gas in storage inventories are recorded using the weighted-average cost method of accounting.

NOTE 9—INCOME TAXES

The provision for income taxes differs from the amount of income tax determined by applying the applicable United States statutory federal income tax rate to income before income taxes as a result of the following:

	Three Months Ended June 30, 2019					Three Months Ended June 30, 2018
(in millions)	Amount			Effective Tax Rate		Amount			Effective Tax Rate
Statutory federal income tax	$	11.4		21.0	%	$	14.3		21.0	%
State income taxes net of federal tax benefit	3.3			6.1	%	4.2			6.2	%
Federal excess deferred tax amortization	(1.2		)	(2.2	)%	7.5			11.1	%
Other	(0.6		)	(1.2	)%	(0.7		)	(1.1	)%
Total income tax expense	$	12.9		23.7	%	$	25.3		37.2	%

06/30/2019 Form 10-Q 11 Wisconsin Public Service Corporation

	Six Months Ended June 30, 2019					Six Months Ended June 30, 2018
(in millions)	Amount			Effective Tax Rate		Amount			Effective Tax Rate
Statutory federal income tax	$	22.7		21.0	%	$	28.1		21.0	%
State income taxes net of federal tax benefit	6.7			6.2	%	8.3			6.2	%
Federal excess deferred tax amortization	(2.5		)	(2.3	)%	5.9			4.4	%
Other	(1.1		)	(1.1	)%	(1.1		)	(0.8	)%
Total income tax expense	$	25.8		23.8	%	$	41.2		30.8	%

The effective tax rates of 23.7% and 23.8% for the three and six months ended June 30, 2019, respectively, differ from the United States statutory federal income tax rate of 21%, primarily due to state income taxes, partially offset by the impact of the Tax Legislation.

The effective tax rates of 37.2% and 30.8% for the three and six months ended June 30, 2018, respectively, differ from the United States statutory federal income tax rate of 21%, primarily due to state income taxes and the accounting treatment of the PSCW's order regarding the benefits associated with the Tax Legislation.

The Tax Legislation, signed into law in December 2017, required our regulated utilities to remeasure their deferred income taxes and we began to amortize the resulting excess deferred income taxes beginning in 2018 in accordance with normalization requirements (see federal excess deferred tax amortization line above). See Note 18, Regulatory Environment, for more information about the Wisconsin rate settlement.

NOTE 10—FAIR VALUE MEASUREMENTS

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).

Fair value accounting rules provide a fair value hierarchy that prioritizes the inputs used to measure fair value. 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). The three levels of the fair value hierarchy are defined as follows:

Level 1 – Quoted prices are available in active markets for identical assets or liabilities as of the reporting date. Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis.

Level 2 – Pricing inputs are observable, either directly or indirectly, but are not quoted prices included within Level 1. Level 2 includes those financial instruments that are valued using external inputs within models or other valuation methods.

Level 3 – Pricing inputs include significant inputs that are generally less observable from objective sources. These inputs may be used with internally developed methods that result in management's best estimate of fair value. Level 3 instruments include those that may be more structured or otherwise tailored to customers' needs.

Assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. We use a mid-market pricing convention (the mid-point between bid and ask prices) as a practical measure for valuing certain derivative assets and liabilities. We primarily use a market approach for recurring fair value measurements and attempt to use valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs.

When possible, we base the valuations of our derivative assets and liabilities on quoted prices for identical assets and liabilities in active markets. These valuations are classified in Level 1. The valuations of certain contracts not classified as Level 1 may be based on quoted market prices received from counterparties and/or observable inputs for similar instruments. Transactions valued using these inputs are classified in Level 2. Certain derivatives are categorized in Level 3 due to the significance of unobservable or internally-developed inputs.

We recognize transfers between levels of the fair value hierarchy at their value as of the end of the reporting period.

The following tables summarize our financial assets and liabilities that were accounted for at fair value on a recurring basis, categorized by level within the fair value hierarchy:

Long-term debt	$	1,315.1	$	1,467.3	$	1,314.7	$	1,372.9

The fair value of long-term debt is categorized within Level 2 of the fair value hierarchy.

NOTE 11—DERIVATIVE INSTRUMENTS

We use derivatives as part of our risk management program to manage the risks associated with the price volatility of purchased power, generation, and natural gas costs for the benefit of our customers. Our approach is non-speculative and designed to mitigate risk. Our regulated hedging programs are approved by the PSCW.

We record derivative instruments on our balance sheets as an asset or liability measured at fair value unless they qualify for the normal purchases and sales exception and are so designated. We continually assess our contracts designated as normal and will

06/30/2019 Form 10-Q 13 Wisconsin Public Service Corporation

discontinue the treatment of these contracts as normal if the required criteria are no longer met. Changes in the derivative's fair value are recognized currently in earnings unless specific hedge accounting criteria are met or we receive regulatory treatment for the derivative. For most energy-related physical and financial contracts in our regulated operations that qualify as derivatives, the PSCW allows the effects of fair value accounting to be offset to regulatory assets and liabilities.

The following table shows our derivative assets and derivative liabilities, none of which are designated as hedging instruments.

On our balance sheets, the amounts recognized for the right to reclaim cash collateral or the obligation to return cash collateral are not offset against the fair value amounts recognized for derivative instruments executed with the same counterparty under the same master netting arrangement. At June 30, 2019 and December 31, 2018, we had posted cash collateral of $5.0 million and $0.5 million, respectively, in our margin accounts. These amounts were recorded on our balance sheets in other current assets.

During the six months ended June 30, 2019, we made contributions and payments of $0.3 million related to our pension plans. We did not contribute to our OPEB plans. We expect to make contributions and payments of $0.4 million related to our pension plans and an insignificant amount related to our OPEB plans during the remainder of 2019, dependent upon various factors affecting us, including our liquidity position and the effects of the Tax Legislation.

NOTE 14—GOODWILL AND OTHER INTANGIBLE ASSETS

Goodwill represents the excess of the cost of an acquisition over the fair value of the identifiable net assets acquired. We had no changes to the carrying amount of goodwill during the six months ended June 30, 2019.

NOTE 15—SEGMENT INFORMATION

We use operating income to measure segment profitability and to allocate resources to our businesses. At June 30, 2019, we reported two segments, which are described below.

Our utility segment includes our electric and natural gas utility operations, which serve customers in northeastern and central Wisconsin. Our electric utility operations are engaged in the generation, distribution, and sale of electricity. Our natural gas utility operations are engaged in the purchase, distribution, and sale of natural gas to retail customers as well as the transportation of customer-owned natural gas.

Our other segment includes equity earnings from our investment in Wisconsin River Power Company.

The following tables show summarized financial information for the three and six months ended June 30, 2019 and 2018, related to our reportable segments:

NOTE 16—COMMITMENTS AND CONTINGENCIES

We have significant commitments and contingencies arising from our operations, including those related to unconditional purchase obligations, environmental matters, and enforcement and litigation matters.

Unconditional Purchase Obligations

We have obligations to distribute and sell electricity and natural gas to our customers and expect to recover costs related to these obligations in future customer rates. In order to meet these obligations, we routinely enter into long-term purchase and sale commitments for various quantities and lengths of time. Our minimum future commitments related to these purchase obligations as of June 30, 2019, were approximately $1.2 billion.

Environmental Matters

Consistent with other companies in the energy industry, we face significant ongoing environmental compliance and remediation obligations related to current and past operations. Specific environmental issues affecting us include, but are not limited to, current and future regulation of air emissions such as sulfur dioxide, nitrogen oxide, fine particulates, mercury, and GHGs; water intake and discharges; disposal of coal combustion products such as fly ash; and remediation of impacted properties, including former manufactured gas plant sites.

Air Quality

National Ambient Air Quality Standards

After completing its review of the 2008 ozone standard, the EPA released a final rule in October 2015, which lowered the limit for ground-level ozone, creating a more stringent standard than the 2008 National Ambient Air Quality Standards. The EPA issued final nonattainment area designations on May 1, 2018. The following counties within our service territory were designated as partial nonattainment: Door, Manitowoc, and Sheboygan shorelines. The state of Wisconsin will need to develop a state implementation plan to bring these areas back into attainment. We will be required to comply with this state implementation plan no earlier than 2020. We believe we are well positioned to meet the requirements associated with the ozone standard and do not expect to incur significant costs to comply.

Mercury and Air Toxics Standards

In December 2018, the EPA proposed to revise the Supplemental Cost Finding for the MATS rule as well as the CAA required RTR. The EPA was required by the United States Supreme Court to review both costs and benefits of complying with the MATS rule. After its review of costs, the EPA determined that it is not appropriate and necessary to regulate hazardous air pollutant emissions from power plants under Section 112 of the CAA. As a result, under the proposed rule, the emission standards and other requirements of the MATS rule first enacted in 2012 would remain in place. The EPA is not proposing to remove coal-and oil-fired power plants from the list of sources that are regulated under Section 112. The EPA also proposes that no revisions to MATS are warranted based on the results of the RTR. As a result, we do not expect the proposed rule to have a material impact on our financial condition or operations.

06/30/2019 Form 10-Q 17 Wisconsin Public Service Corporation

Climate Change

In July 2019, the EPA published the ACE rule, which provides existing coal-fired generating units with standards for achieving GHG emission reductions. The rule was finalized in conjunction with two other separate and distinct rulemakings, (1) the repeal of the Clean Power Plan, and (2) revised implementing regulations for ACE, ongoing emissions guidelines, and all future emission guidelines for existing sources issued under CAA section 111(d). Every state's plan to implement ACE would need to focus on reducing GHG emissions by improving the efficiency of fossil-fueled power plants. The rule is being litigated.

In December 2018, the EPA proposed to revise the New Source Performance Standards for GHG emissions from new, modified, and reconstructed fossil-fueled power plants. The EPA determined that the BSER for new, modified, and reconstructed coal units is highly efficient generation that would be equivalent to supercritical steam conditions for larger units and subcritical steam conditions for smaller units. This proposed BSER would replace the determination from the previous rule, which identified BSER as partial carbon capture and storage.

In April 2019, WEC Energy Group issued a climate report, which analyzes its GHG reduction goals with respect to international efforts to limit future global temperature increases to less than two degrees Celsius. WEC Energy Group will continue to update this analysis as climate-change policies and relevant technologies evolve over time with a focus on preserving fuel diversity, lowering costs for customers, and reducing long-term GHG emissions.

WEC Energy Group's plan, which includes us, is to work with its industry peers, environmental groups, public policy makers, and customers, with goals of reducing CO₂ emissions by approximately 40% and 80% below 2005 levels by 2030 and 2050, respectively. As a result of WEC Energy Group's generation reshaping plan, we retired approximately 300 MW of coal generation in 2018, consisting of the Pulliam power plant and the jointly-owned Edgewater Unit 4 generation units.

Water Quality

Clean Water Act Cooling Water Intake Structure Rule

In August 2014, the EPA issued a final regulation under Section 316(b) of the Clean Water Act that requires the location, design, construction, and capacity of cooling water intake structures at existing power plants to reflect the BTA for minimizing adverse environmental impacts. The rule became effective in October 2014 and applies to all of our existing generating facilities with cooling water intake structures.

We have received BTA determinations for Weston Units 2, 3, and 4. As a result, we do not expect to incur any significant additional costs to comply with this regulation.

Steam Electric Effluent Limitation Guidelines

The EPA's final ELG rule took effect in January 2016. This rule created new requirements for several types of power plant wastewaters. The requirement that affects us relates to discharge limits for BATW.

This rule is being litigated and various petitions challenging it were consolidated in the United States Court of Appeals for the Fifth Circuit. In April 2017, the EPA issued an administrative stay of certain compliance deadlines while further reviewing the rule. In September 2017, the EPA issued a final rule (Postponement Rule) to postpone the earliest compliance date to November 1, 2020 for the BATW. The latest ELG rule compliance date remains December 31, 2023 for any new wastewater treatment requirements contained in power plant discharge permits.

As a result of past capital investments completed to address ELG compliance, we believe our fleet overall is well positioned to meet the regulations. Our power plant facilities already have advanced wastewater treatment technologies installed that meet many of the discharge limits established by this rule. However, in its current form, the ELG rule would require additional wastewater treatment retrofits and the installation of other equipment to minimize process water use. Due to completed generating unit retirements, we believe the only facility that would require bottom ash system modifications is Weston Unit 3. Based on preliminary engineering, the estimated rule compliance cost is approximately $20 million.

Manufactured Gas Plant Remediation

We have identified sites at which we or a predecessor company owned or operated a manufactured gas plant or stored manufactured gas. We have also identified other sites that may have been impacted by historical manufactured gas plant activities. We are responsible for the environmental remediation of these sites, some of which are in the EPA Superfund Alternative Approach Program. We are also working with various state jurisdictions in our investigation and remediation planning. These sites are at various stages of investigation, monitoring, remediation, and closure.

In addition, we are coordinating the investigation and cleanup of some of these sites subject to the jurisdiction of the EPA under what is called a "multisite" program. This program involves prioritizing the work to be done at the sites, preparation and approval of documents common to all of the sites, and use of a consistent approach in selecting remedies. At this time, we cannot estimate future remediation costs associated with these sites beyond those described below.

The future costs for detailed site investigation, future remediation, and monitoring are dependent upon several variables including, among other things, the extent of remediation, changes in technology, and changes in regulation. Historically, our regulators have allowed us to recover incurred costs, net of insurance recoveries and recoveries from potentially responsible parties, associated with the remediation of manufactured gas plant sites. Accordingly, we have established regulatory assets for costs associated with these sites.

We have established the following regulatory assets and reserves related to manufactured gas plant sites:

(in millions)	June 30, 2019		December 31, 2018
Regulatory assets	$	125.2	$	108.3
Reserves for future remediation	104.2		90.3

Consent Decrees

Weston and Pulliam Power Plants Consent Decree

In November 2009, the EPA issued an NOV to us, which alleged violations of the CAA's New Source Review requirements relating to certain projects completed at the Weston and Pulliam power plants from 1994 to 2009. We entered into a Consent Decree with the EPA resolving this NOV. This Consent Decree was entered by the United States District Court for the Eastern District of Wisconsin in March 2013. We retired Pulliam Units 7 and 8 in October 2018. We also completed the mitigation projects required and received a completeness letter from the EPA in October 2018. We have started the process to terminate the Consent Decree.

Joint Ownership Power Plants Consent Decree – Columbia and Edgewater

In December 2009, the EPA issued an NOV to Wisconsin Power and Light, the operator of the Columbia and Edgewater plants, and the other joint owners of these plants, including Madison Gas and Electric, WE (former co-owner of an Edgewater unit), and us. The NOV alleged violations of the CAA's New Source Review requirements related to certain projects completed at those plants. We, along with Wisconsin Power and Light, Madison Gas and Electric, and WE, entered into a Consent Decree with the EPA resolving this NOV. This Consent Decree was entered by the United States District Court for the Western District of Wisconsin in June 2013. As a result of the continued implementation of the Consent Decree related to the jointly owned Columbia and Edgewater plants, the Edgewater 4 generating unit was retired in September 2018.

Enforcement and Litigation Matters

We are involved in legal and administrative proceedings before various courts and agencies with respect to matters arising in the ordinary course of business. Although we are unable to predict the outcome of these matters, management believes that appropriate reserves have been established and that final settlement of these actions will not have a material effect on our financial condition or results of operations.

NOTE 18—REGULATORY ENVIRONMENT

2020 and 2021 Rates

In March 2019, we filed an application with the PSCW to increase our retail electric and natural gas rates, effective January 1, 2020. Our proposal is targeting an effective electric rate increase of approximately $49 million (4.9%) in 2020 and an additional increase of $49 million (4.9%) in 2021. For our natural gas customers, the proposal is targeting an effective rate increase of approximately $7 million (2.4%) in 2020 and an additional increase of $7 million (2.4%) in 2021. Our proposal reflects a ROE of 10.35% and a common equity component average of 52.0% on a financial basis. We also proposed to continue having an earnings sharing mechanism through 2021.

The proposed increases in our electric rates were driven by the inclusion of our SMRP, the Forward Wind Energy Center, and our investments in two solar projects in rates, along with continued investments in system reliability and the recovery of various regulatory deferrals, including the deferral of the revenue requirement for ReACT™ costs above a previously authorized level. Our proposed electric rates reflect our request to use $40 million of previously deferred tax benefits from the Tax Legislation to partially offset these increases. Our proposal also includes our request for approval to continue collecting the carrying value of Pulliam units 7 and 8 and the Edgewater 4 generating unit using the current approved composite depreciation rates, in addition to a return on the remaining carrying value of the units.

The proposed increases at our natural gas utility were driven by continued investment in our natural gas distribution system. Our proposed 2020 natural gas rate increase is net of approximately $7 million of previously deferred tax benefits from the Tax Legislation.

A final order is expected from the PSCW by the end of 2019, with rates effective January 1, 2020.

2018 and 2019 Rates

During April 2017, we, along with WE and WG, filed an application with the PSCW for approval of a settlement agreement we made with several of our commercial and industrial customers regarding 2018 and 2019 base rates. In September 2017, the PSCW issued an order that approved the settlement agreement, which freezes base rates through 2019 for our electric and natural gas customers. Based on the PSCW order, our authorized ROE remains at 10.0%, and our current capital cost structure will remain unchanged through 2019.

In addition to freezing base rates, the settlement agreement extends and expands the electric real-time market pricing program options for large commercial and industrial customers. Additionally, the agreement allows us to extend, through 2019, the deferral for the revenue requirement of ReACT™ costs above the authorized $275.0 million level, and other deferrals related to our electric real-time market pricing program and network transmission expenses. The total cost of the ReACT™ project, excluding $51 million of AFUDC, was $342 million.

Pursuant to the settlement agreement, we also agreed to adopt, beginning in 2018, the earnings sharing mechanism that has been in place for WE and WG since January 2016, and agreed to keep the mechanism in place through 2019. Under this earnings sharing mechanism, if we earn above our authorized ROE, 50% of the first 50 basis points of additional utility earnings must be shared with customers. All utility earnings above the first 50 basis points must also be shared with customers.

Solar Generation Projects

On May 31, 2018, we, along with an unaffiliated utility, filed an application with the PSCW for approval to acquire ownership interests in two solar projects in Wisconsin. Badger Hollow I will be located in Iowa County, Wisconsin, and Two Creeks Solar Project will be located in Manitowoc County, Wisconsin. We will own 100 MW of the output of each project for a total of 200 MW. Our share of the cost of both projects is estimated to be $260 million. The PSCW approved the acquisition of these two projects in April 2019. Commercial operation for both projects is targeted for the end of 2020.

NOTE 19—NEW ACCOUNTING PRONOUNCEMENTS

Financial Instruments Credit Losses

In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. This ASU introduces a new impairment model known as the current expected credit loss model. The ASU requires a financial asset measured at amortized cost to be presented at the net amount expected to be collected. Previously, recognition of the full amount of credit losses was generally delayed until the loss was probable of occurring. We are currently assessing the effects this guidance may have on our financial statements.

Cloud Computing

In August 2018, the FASB issued ASU 2018-15, Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. The standard allows entities who are customers in hosting arrangements that are service contracts to apply the existing internal-use software guidance to determine which implementation costs to capitalize as an asset related to the service contract and which costs to expense. The guidance specifies classification for capitalizing implementation costs and related amortization expense within the financial statements and requires additional disclosures. The guidance will be effective for annual reporting periods, including interim reporting within those periods, beginning after December 15, 2019. Early adoption is permitted and can be applied either retrospectively or prospectively. We are currently evaluating the transition methods and the impact the adoption of this standard may have on our financial statements.

Disclosure Requirements for Defined Benefit Plans

In August 2018, the FASB issued ASU 2018-14, Disclosure Framework: Changes to the Disclosure Requirements for Defined Benefit Plans. The pronouncement modifies the disclosure requirements for defined benefit pension and other postretirement benefit plans. The guidance removes disclosures that are no longer considered cost beneficial, clarifies the specific requirements of disclosures and adds disclosure requirements identified as relevant. The modifications affect annual period disclosures and must be applied on a retrospective basis to all periods presented. The guidance will be effective for annual reporting periods ending after December 15, 2020, with early adoption permitted. We are currently evaluating the effects of this pronouncement on our Notes to Consolidated Financial Statements.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

CORPORATE DEVELOPMENTS

The following discussion should be read in conjunction with the accompanying financial statements and related notes and our 2018 Annual Report on Form 10-K.

Introduction

We are an electric and natural gas utility and an indirect wholly owned subsidiary of WEC Energy Group. We derive revenues primarily from the distribution and sale of electricity and natural gas to retail customers in northeastern Wisconsin. We also provide wholesale electric service to numerous utilities and cooperatives for resale. We conduct our business primarily through our utility reportable segment. See Note 15, Segment Information, for more information on our reportable business segments.

Corporate Strategy

Our goal is to continue to build and sustain long-term value for customers and shareholders by focusing on the fundamentals of our business: reliability; operating efficiency; financial discipline; customer care; and safety.

Reshaping Our Generation Fleet

WEC Energy Group has developed and is executing a plan to reshape its generation portfolio. This plan will balance reliability and customer cost with environmental stewardship. Taken as a whole, this plan should reduce costs to customers, preserve fuel diversity, and lower carbon emissions. Generation reshaping includes retiring older fossil fuel generation units, building state-of-the-art natural gas generation, and investing in cost-effective zero-carbon generation with a goal of reducing CO₂ emissions by approximately 40% below 2005 levels by 2030 and by approximately 80% below 2005 levels by 2050. WEC Energy Group has retired approximately 1,800 MW of coal generation since the beginning of 2018 across its electric utilities, and expects to add additional natural gas-fired generating units and renewable generation, including utility-scale solar projects. We retired the Edgewater 4 generating unit in September 2018, and the Pulliam power plant in October 2018.

As part of its commitment to invest in zero-carbon generation, WEC Energy Group plans to invest in utility scale solar of up to 350 MW within its Wisconsin segment, which includes us. We have partnered with an unaffiliated utility to acquire ownership interests in two proposed solar projects in Wisconsin. Badger Hollow Solar Farm I will be located in Iowa County, Wisconsin, and Two Creeks Solar Project will be located in Manitowoc County, Wisconsin. We will own 100 MW of the output of each project for a total of 200 MW. The PSCW approved the acquisition of these two projects in April 2019. Commercial operation for both projects is targeted for the end of 2020. As the cost of renewable energy generation continues to decline, these solar projects have become cost effective opportunities for us and our customers to participate in renewable energy.

Reliability

We have made significant reliability-related investments in recent years, and plan to continue strengthening and modernizing our generation fleet and distribution networks to further improve reliability.

We continue work on our SMRP, which involves modernizing parts of our electric distribution system, including burying or upgrading lines. The project focuses on constructing facilities to improve the reliability of electric service we provide to our customers. We also continue to upgrade our electric and natural gas distribution systems to enhance reliability.

Operating Efficiency

We continually look for ways to optimize the operating efficiency of our company. For example, we are making progress on our Advanced Metering Infrastructure program, replacing aging meter-reading equipment on both our network and customer property. An integrated system of smart meters, communication networks, and data management programs enables two-way communication between us and our customers. This program reduces the manual effort for disconnects and reconnects and enhances outage management capabilities.

06/30/2019 Form 10-Q 22 Wisconsin Public Service Corporation

WEC Energy Group continues to focus on integrating and improving business processes and consolidating its IT infrastructure across all of its companies. We expect these efforts to continue to drive operational efficiency and to put us in position to effectively support plans for future growth.

Financial Discipline

A strong adherence to financial discipline is essential to earning our authorized ROE and maintaining a strong balance sheet, stable cash flows, and quality credit ratings.

We follow an asset management strategy that focuses on investing in and acquiring assets consistent with our strategic plans, as well as disposing of assets, including property, plants, and equipment, that are no longer performing as intended, or have an unacceptable risk profile. See Note 2, Acquisition, for more information about our acquisition of a portion of a wind energy generation facility in Wisconsin.

Exceptional Customer Care

Our approach is driven by an intense focus on delivering exceptional customer care every day. We strive to provide the best value for our customers by embracing constructive change, demonstrating personal responsibility for results, leveraging our capabilities and expertise, and using creative solutions to meet or exceed our customers’ expectations.

One example of how we obtain feedback from our customers is through our "We Care" calls, where our employees contact customers after a completed service call. Customer satisfaction is a priority, and making "We Care" calls is one of the main methods we use to gauge our performance to improve customer satisfaction.

Safety

We have a long-standing commitment to both workplace and public safety, and under our "Target Zero" mission, we have an ultimate goal of zero incidents, accidents, and injuries. We also set goals around injury-prevention activities that raise awareness and facilitate conversations about employee safety. Our corporate safety program provides a forum for addressing employee concerns, training employees and contractors on current safety standards, and recognizing those who demonstrate a safety focus.

RESULTS OF OPERATIONS

THREE MONTHS ENDED JUNE 30, 2019

Earnings

Our earnings for the three months ended June 30, 2019 were $41.5 million, compared to $42.7 million for the same quarter in 2018. See below for additional information on the $1.2 million decrease in earnings.

Non-GAAP Financial Measures

The discussion below addresses the operating income contribution of our utility segment and includes financial information prepared in accordance with GAAP, as well as electric margins and natural gas margins, which are not measures of financial performance under GAAP. Electric margin (electric revenues less fuel and purchased power costs) and natural gas margin (natural gas revenues less cost of natural gas sold) are non-GAAP financial measures because they exclude other operation and maintenance expense, depreciation and amortization, and property and revenue taxes.

We believe that electric and natural gas margins provide a useful basis for evaluating utility operations since the majority of prudently incurred fuel and purchased power costs, as well as prudently incurred natural gas costs, are passed through to customers in current rates. As a result, management uses electric and natural gas margins internally when assessing the operating performance of our utility segment as these measures exclude the majority of revenue fluctuations caused by changes in these expenses. Similarly, the presentation of electric and natural gas margins herein is intended to provide supplemental information for investors regarding our operating performance.

06/30/2019 Form 10-Q 23 Wisconsin Public Service Corporation

Our electric margins and natural gas margins may not be comparable to similar measures presented by other companies.  Furthermore, these measures are not intended to replace operating income as determined in accordance with GAAP as an indicator of our utility segment operating performance. Our utility segment operating income for the three months ended June 30, 2019 and 2018 was $59.8 million and $72.6 million, respectively. The operating income discussion below includes a table that provides the calculation of electric margins and natural gas margins, along with a reconciliation to utility segment operating income.

Utility Segment Contribution to Operating Income

The following table compares our utility segment's contribution to operating income during the second quarter of 2019, compared with the same quarter in 2018, including favorable or better, "B", and unfavorable or worse, "W", variances.

During the three months ended June 30, 2019 and 2018, $34.0 million and $31.3 million, respectively, of costs were billed to us by transmission providers.

⁽²⁾  Regulatory amortizations and other pass through expenses are substantially offset in margins and therefore do not have a significant impact on operating income.

Electric Utility Margins

Electric utility margins decreased $13.8 million during the second quarter of 2019, compared with the same quarter in 2018. The significant factors impacting the lower electric utility margins were:

• A $7.2 million decrease in margins related to savings from the Tax Legislation that we are required to return to customers through bill credits or reductions in other regulatory assets. This decrease in margins was offset by the net impact of a $12.3 million decrease in income taxes and a $5.1 million increase in depreciation and amortization expense. We received the PSCW order in May 2018, which required us to use 40% of the current 2018 and 2019 tax benefits to reduce certain regulatory assets. Prior to receiving the order, we recorded all of the expected benefits related to the Tax Legislation as if they would be returned to customers through bill credits, which resulted in a decrease in revenues in the first quarter of 2018. After receiving the order during the second quarter of 2018, we reversed a portion of this decrease in revenues we had assumed would be returned to customers as bill credits and instead applied the tax savings by reducing the regulatory assets.

• A $6.8 million decrease related to lower retail sales volumes during the second quarter of 2019, primarily driven by unfavorable weather. As measured by cooling degree days, the second quarter of 2019 was 63.7% cooler than the same quarter in 2018. As measured by heating degree days, the second quarter of 2019 was 3.8% warmer than the same quarter in 2018.

Natural Gas Utility Margins

Natural gas utility margins decreased $0.1 million during the second quarter of 2019, compared with the same quarter in 2018.

06/30/2019 Form 10-Q 25 Wisconsin Public Service Corporation

Operating Income

Operating income at the utility segment decreased $12.8 million during the second quarter of 2019, compared with the same quarter in 2018. This decrease was driven by the $13.9 million decrease in margins discussed above, partially offset by $1.1 million of lower operating expenses (which include other operation and maintenance, depreciation and amortization, and property and revenue taxes).

The significant factors impacting the decrease in operating expenses during the second quarter of 2019, compared with the same quarter in 2018, were:

• A $6.2 million decrease in operation and maintenance expenses across all of our plants, in part due to the retirements of Edgewater Unit 4 in September 2018 and Pulliam Units 7 and 8 in October 2018. This resulted in lower maintenance and labor costs during the second quarter of 2019.

• A $2.6 million decrease in costs related to renewable energy projects associated with the reshaping of WEC Energy Group's generation fleet during the second quarter of 2019, compared with the same period in 2018.

These decreases in operating expenses were partially offset by a $7.2 million increase in depreciation and amortization, driven by capital expenditures as we continue to execute on our capital plans, as well as an increase related to the reduction of certain regulatory assets as a result of the PSCW's May 2018 order addressing the Tax Legislation, as discussed in electric margins above.

⁽¹⁾  Represents transmission expense that we are authorized to collect in rates, in accordance with the PSCW's approval of escrow accounting for our ATC and MISO network transmission expenses. As a result, we defer as a regulatory asset or liability the difference between actual transmission costs and those included in rates until recovery or refund is authorized in a future rate proceeding. During the six months ended June 30, 2019 and 2018, $69.5 million and $67.6 million, respectively, of costs were billed to us by transmission providers.

⁽²⁾  Regulatory amortizations and other pass through expenses are substantially offset in margins and therefore do not have a significant impact on operating income.

Electric Utility Margins

Electric utility margins decreased $18.2 million during the six months ended June 30, 2019, compared with the same period in 2018. The significant factors impacting the lower electric utility margins were:

• A $7.7 million decrease related to lower retail sales volumes during the six months ended June 30, 2019, primarily driven by unfavorable weather in the second quarter of 2019. As measured by cooling degree days, the six months ended June 30, 2019 were 63.7% cooler than the same period in 2018.

• A $4.7 million decrease in margins related to savings from the Tax Legislation that we are required to return to customers through bill credits or reductions in other regulatory assets. This decrease in margins was offset by the net impact of a $12.3 million decrease in income taxes and a $7.6 million increase in depreciation and amortization expense. We received the PSCW order in May 2018, which required us to use 40% of the current 2018 and 2019 tax benefits to reduce certain regulatory assets.

06/30/2019 Form 10-Q 28 Wisconsin Public Service Corporation

• A $3.5 million decrease in wholesale margins driven by lower sales volumes to UMERC. UMERC's new natural gas-fired generation in the Upper Peninsula of Michigan began commercial operation on March 31, 2019, at which time we ceased providing wholesale services to UMERC.

Natural Gas Utility Margins

Natural gas utility margins increased $2.0 million during the six months ended June 30, 2019, compared with the same period in 2018. The most significant factor impacting the higher natural gas utility margins was higher sales volumes, primarily driven by colder winter weather, customer growth, and higher use per residential customer during the six months ended June 30, 2019, compared with the same period in 2018.

Operating Income

Operating income at the utility segment decreased $21.5 million during the six months ended June 30, 2019, compared with the same period in 2018. This decrease was driven by the $16.2 million net decrease in margins discussed above and by $5.3 million of higher operating expenses (which include other operation and maintenance, depreciation and amortization, and property and revenue taxes).

The significant factors impacting the increase in operating expenses during the six months ended June 30, 2019, compared with the same period in 2018, were:

• An $11.6 million increase in depreciation and amortization, driven by capital expenditures as we continue to execute on our capital plan, as well as an increase related to the reduction of certain regulatory assets as a result of the PSCW's May 2018 order addressing the Tax Legislation, as discussed in electric margins above.

• A $4.4 million increase in benefit costs, primarily related to deferred compensation.

These increases in operating expenses were partially offset by a $10.1 million decrease in operation and maintenance expenses across all of our plants, in part due to the retirements of Edgewater Unit 4 in September 2018 and Pulliam Units 7 and 8 in October 2018. This resulted in lower maintenance and labor costs during the six months ended June 30, 2019.

Interest expense increased $5.4 million during the six months ended June 30, 2019, compared with the same period in 2018, primarily due to higher long-term debt balances and higher interest rates. The increase in debt balances is primarily related to continued capital investments.

Income Tax Expense

Our effective tax rate decreased by 7.0% when compared with the six months ended June 30, 2018, primarily due to the impact of the Tax Legislation. See Note 9, Income Taxes, and Note 18, Regulatory Environment, for more information.

We expect our 2019 annual effective tax rate to be between 24.0% and 25.0%.

LIQUIDITY AND CAPITAL RESOURCES

Cash Flows

The following table summarizes our cash flows during the six months ended June 30:

(in millions)	2019			2018			Change in 2019 Over 2018
Cash provided by (used in):
Operating activities	$	157.4		$	252.4		$	(95.0	)
Investing activities	(178.2		)	(292.6		)	114.4
Financing activities	25.7			34.1			(8.4		)

Operating Activities

Net cash provided by operating activities decreased $95.0 million during the six months ended June 30, 2019, compared with the same period in 2018, driven by:

• A $79.5 million decrease in cash from higher payments for other operation and maintenance expenses. During the six months ended June 30, 2019, our payments were higher for accounts payable and benefit costs, compared with the same period in 2018.

• A $24.1 million decrease in cash primarily related to the impact of the Tax Legislation, which resulted in lower overall collections from customers during the six months ended June 30, 2019, compared with the same period in 2018.

• A $10.9 million decrease in cash due to higher collateral requirements during the six months ended June 30, 2019, compared with the same period in 2018, driven by an increase in our derivative liabilities.

These decreases in net cash provided by operating activities were partially offset by a $20.9 million increase in cash, driven by the timing of payments for natural gas, which were lower during the six months ended June 30, 2019.

Investing Activities

Net cash used in investing activities decreased $114.4 million during the six months ended June 30, 2019, compared with the same period in 2018, driven by:

• The acquisition of Forward Wind Energy Center in April 2018 for $77.1 million. See Note 2, Acquisition, for more information.

• A payment of $23.7 million to WBS during the six months ended June 30, 2018 for the transfer of software assets to us.

• A $7.2 million decrease in cash paid for capital expenditures during the six months ended June 30, 2019, compared with the same period in 2018, which is discussed in more detail below.

06/30/2019 Form 10-Q 30 Wisconsin Public Service Corporation

Capital Expenditures

Capital expenditures for the six months ended June 30 were as follows:

(in millions)	2019		2018		Change in 2019 Over 2018
Capital expenditures	$	186.2	$	193.4	$	(7.2	)

The decrease in cash paid for capital expenditures during the six months ended June 30, 2019, compared with the same period in 2018, was driven by the implementation of an enterprise resource planning system and our AMI program during the six months ended June 30, 2018. These decreases in cash paid for capital expenditures were partially offset by increased capital expenditures related to upgrades to our natural gas distribution system.

See Capital Resources and Requirements – Capital Requirements – Significant Capital Projects below for more information.

Financing Activities

Net cash provided by financing activities decreased $8.4 million during the six months ended June 30, 2019, compared with the same period in 2018. This decrease in cash was primarily driven by a $43.2 million net decrease in cash due to $19.1 million of net repayments of commercial paper during the six months ended June 30, 2019, compared with $24.1 million of net borrowings of commercial paper during the same period of 2018. This decrease in cash was partially offset by a $35.0 million increase in equity contributions received from our parent during the six months ended June 30, 2019, compared with the same period in 2018, to balance our capital structure.

For more information on our short-term financing activities, see Note 6, Short-Term Debt and Lines of Credit.

Capital Resources and Requirements

Capital Resources

Liquidity

We anticipate meeting our capital requirements for our existing operations through internally generated funds and short-term borrowings, supplemented by the issuance of intermediate or long-term debt securities, depending on market conditions and other factors, and equity contributions from our parent.

We currently have access to the capital markets and have been able to generate funds internally and externally to meet our capital requirements. Our ability to attract the necessary financial capital at reasonable terms is critical to our overall strategic plan. We currently believe that we have adequate capacity to fund our operations for the foreseeable future through our existing borrowing arrangement, access to capital markets, and internally generated cash.

We maintain a bank back-up credit facility, which provides liquidity support for our obligations with respect to commercial paper and for general corporate purposes. We review our bank back-up credit facility needs on an ongoing basis and expect to be able to maintain adequate credit facilities to support our operations. See Note 6, Short-Term Debt and Lines of Credit, for more information on our credit facility.

Working Capital

As of June 30, 2019, our current liabilities exceeded our current assets by $122.9 million. We do not expect this to have any impact on our liquidity since we believe we have adequate back-up lines of credit in place for our ongoing operations. We also believe that we can access the capital markets to finance our construction programs and to refinance current maturities of long-term debt, if necessary.

06/30/2019 Form 10-Q 31 Wisconsin Public Service Corporation

Credit Rating Risk

We do not have any credit agreements that would require material changes in payment schedules or terminations as a result of a credit rating downgrade. We have certain agreements in the form of commodity contracts that, in the event of a credit rating downgrade, could result in a reduction of our unsecured credit granted by counterparties.

In addition, access to capital markets at a reasonable cost is determined in large part by credit quality. Any credit ratings downgrade could impact our ability to access capital markets.

Subject to other factors affecting the credit markets as a whole, we believe our current ratings should provide a significant degree of flexibility in obtaining funds on competitive terms. However, these security ratings reflect the views of the rating agency only. An explanation of the significance of these ratings may be obtained from the rating agency. Such ratings are not a recommendation to buy, sell, or hold securities. Any rating can be revised upward or downward or withdrawn at any time by a rating agency.

If we are unable to successfully take actions to manage any adverse impacts of the Tax Legislation, or if additional interpretations, regulations, amendments or technical corrections exacerbate the adverse impacts of the Tax Legislation, the legislation could result in credit rating agencies placing our credit ratings on negative outlook or downgrading our credit ratings. Any such actions by credit rating agencies may make it more difficult and costly for us to issue future debt securities and certain other types of financing and could increase borrowing costs under our credit facility.

Capital Requirements

Significant Capital Projects

We have several capital projects that will require significant capital expenditures over the next three years and beyond. All projected capital requirements are subject to periodic review and may vary significantly from estimates, depending on a number of factors. These factors include environmental requirements, regulatory restraints and requirements, impacts from the Tax Legislation, additional changes in tax laws and regulations, acquisition and development opportunities, market volatility, and economic trends. Our estimated capital expenditures and acquisitions for the next three years are as follows:

(in millions)
2019	$	505.7
2020	602.7
2021	379.8
Total	$	1,488.2

We are continuing work on the SMRP. This project involves modernizing parts of our electric distribution system, including burying or upgrading lines. The project focuses on constructing facilities to improve the reliability of electric service that we provide to our customers. We expect to invest approximately $185 million between 2019 and 2021 on this project. We also continue to upgrade our electric and natural gas distribution systems to enhance reliability. These upgrades include the AMI program. AMI is an integrated system of smart meters, communication networks and data management systems that enable two-way communication between utilities and customers.

Additionally, as part of our commitment to invest in zero-carbon generation, we plan to invest in utility scale solar. We have partnered with an unaffiliated utility to acquire ownership interests in two proposed solar projects in Wisconsin. Badger Hollow I will be located in Iowa County, Wisconsin, and Two Creeks Solar Project will be located in Manitowoc County, Wisconsin. We will own 100 MW of the output of each project for a total of 200 MW. Our share of the cost of both projects is estimated to be $260 million. Commercial operation for both projects is targeted for the end of 2020. Solar generation technology has greatly improved, has become more cost-effective, and it complements our summer demand curve.

Off-Balance Sheet Arrangements

We are a party to various financial instruments with off-balance sheet risk as a part of our normal course of business, including financial guarantees and letters of credit that support construction projects, commodity contracts, and other payment obligations. We believe that these agreements do not have, and are not reasonably likely to have, a current or future material effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures, or capital resources. See Note 6, Short-Term Debt and Lines of Credit, and Note 12, Guarantees, for more information.

06/30/2019 Form 10-Q 32 Wisconsin Public Service Corporation

Contractual Obligations

For information about our commitments, see Contractual Obligations in Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations – Capital Resources and Requirements in our 2018 Annual Report on Form 10-K. There were no material changes to our commitments outside the ordinary course of business during the six months ended June 30, 2019.

FACTORS AFFECTING RESULTS, LIQUIDITY, AND CAPITAL RESOURCES

The following is a discussion of certain factors that may affect our results of operations, liquidity, and capital resources. The following discussion should be read together with the information in Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations – Factors Affecting Results, Liquidity, and Capital Resources in our 2018 Annual Report on Form 10-K, which provides a more complete discussion of factors affecting us, including market risks and other significant risks, competitive markets, environmental matters, critical accounting policies and estimates, and other matters.

Market Risks and Other Significant Risks

We are exposed to market and other significant risks as a result of the nature of our business and the environment in which we operate. These risks include, but are not limited to, the regulatory recovery risk described below. See Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations – Factors Affecting Results, Liquidity, and Capital Resources – Market Risks and Other Significant Risks in our 2018 Annual Report on Form 10-K for a discussion of other significant risks applicable to us.

Regulatory Recovery

Regulated entities are allowed to defer certain costs that would otherwise be charged to expense if the regulated entity believes the recovery of those costs is probable. We record regulatory assets pursuant to specific orders or by a generic order issued by the PSCW. Recovery of the deferred costs in future rates is subject to the review and approval by the PSCW. We assume the risks and benefits of ultimate recovery of these items in future rates. If the recovery of the deferred costs, including those referenced below, is not approved by the PSCW, the costs would be charged to income in the current period. The PSCW can impose liabilities on a prospective basis for amounts previously collected from customers and for amounts that are expected to be refunded to customers. We record these items as regulatory liabilities.

Due to the Tax Legislation signed into law in December 2017, we remeasured our deferred taxes and recorded a tax benefit of $442.2 million. We have been returning the amortization of this tax benefit to ratepayers through bill credits and reductions to other regulatory assets, which we expect to continue.

We have requested recovery of the costs related to the following projects in our pending rate proceeding that we filed with the PSCW in March 2019.

• In June 2016, the PSCW approved the deferral of costs related to our ReACT™ project above the originally authorized $275.0 million level through 2017. The total cost of the ReACT™ project, excluding $51 million of AFUDC, was $342 million. In September 2017, the PSCW approved an extension of this deferral through 2019 as part of a settlement agreement. We cannot collect these deferred costs without prior approval from the PSCW.

• Prior to its acquisition by WEC Energy Group, Integrys initiated an information technology project with the goal of improving the customer experience at its subsidiaries, including us. Specifically, the project is expected to provide functional and technological benefits to the billing, call center, and credit collection functions. As of June 30, 2019, we had not received any significant disallowances of the costs incurred for this project. We will be required to obtain approval for the recovery of additional costs incurred through the completion of this long-term project.

See Note 18, Regulatory Environment, for more information regarding our pending rate proceeding and previously issued rate order.

06/30/2019 Form 10-Q 33 Wisconsin Public Service Corporation

Environmental Matters

See Note 16, Commitments and Contingencies, for a discussion of certain environmental matters affecting us, including rules and regulations relating to air quality, water quality, land quality, and climate change.

Other Matters

Tax Cuts and Jobs Act of 2017

In December 2017, the Tax Legislation was signed into law. In May 2018, the PSCW issued a written order regarding how to refund certain tax savings from the Tax Legislation to our ratepayers. We expect that the various remaining impacts of the Tax Legislation on our operations will be addressed in our pending rate case we filed with the PSCW in March 2019. See Note 18, Regulatory Environment, for more information on our pending rate case. In July 2019, the Federal Energy Regulatory Commission approved our formula rate tariff, which incorporated the impact of the Tax Legislation. Formula rate customers will receive a monthly bill credit through the end of 2019, which will include the customer's tax savings, including interest.

ITEM 4. CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

Our management, with the participation of our principal executive officer and principal financial officer, has evaluated the effectiveness of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this report. Based upon such evaluation, our principal executive officer and principal financial officer have concluded that, as of the end of such period, our disclosure controls and procedures are effective: (i) in recording, processing, summarizing, and reporting, on a timely basis, information required to be disclosed by us in the reports that we file or submit under the Exchange Act; and (ii) to ensure that information required to be disclosed in the reports that we file or submit under the Exchange Act is accumulated and communicated to our management, including our principal executive officer and principal financial officer, to allow timely decisions regarding required disclosure.

Changes in Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting (as such term is defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) during the second quarter of 2019 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
