CMS Energy Corporation

Consumers Energy Company

Management’s Discussion and Analysis of Financial Condition and Results of Operations

This MD&A is a combined report of CMS Energy and Consumers.

Executive Overview

CMS Energy is an energy company operating primarily in Michigan. It is the parent holding company of several subsidiaries, including Consumers, an electric and gas utility, and CMS Enterprises, primarily a domestic independent power producer and marketer. Consumers’ electric utility operations include the generation, purchase, transmission, distribution, and sale of electricity, and Consumers’ gas utility operations include the purchase, transmission, storage, distribution, and sale of natural gas. Consumers’ customer base consists of a mix of residential, commercial, and diversified industrial customers. CMS Enterprises, through its subsidiaries and equity investments, is engaged in domestic independent power production, including the development and operation of renewable generation, and the marketing of independent power production.

CMS Energy and Consumers manage their businesses by the nature of services each provides. CMS Energy operates principally in three business segments: electric utility; gas utility; and enterprises, its non-utility operations and investments. Consumers operates principally in two business segments: electric utility and gas utility. CMS Energy’s and Consumers’ businesses are affected primarily by:

• regulation and regulatory matters

• state and federal legislation

• economic conditions

• weather

• energy commodity prices

• interest rates

• their securities’ credit ratings

The Triple Bottom Line

CMS Energy’s and Consumers’ purpose is to achieve world class performance while delivering hometown service. In support of this purpose, the companies employ the “Consumers Energy Way,” a lean operating model designed to improve safety, quality, cost, delivery, and employee morale.

12

CMS Energy and Consumers measure their progress toward the purpose by considering their impact on the “triple bottom line” of people, planet, and profit, which is underpinned by performance; this consideration takes into account not only the economic value that the companies create for customers and investors, but also their responsibility to social and environmental goals. The triple bottom line balances the interests of the companies’ employees, customers, suppliers, regulators, creditors, Michigan’s residents, the investment community, and other stakeholders, and it reflects the broader societal impacts of the companies’ activities.

Consumers’ Sustainability Report, which is available to the public, describes the company’s progress toward world class performance measured in the areas of people, planet, and profit.

People: The people element of the triple bottom line represents CMS Energy’s and Consumers’ commitment to their employees, their customers, the residents of local communities in which the companies do business, and other stakeholders.

The safety of employees, customers, and the general public is a priority of CMS Energy and Consumers. Accordingly, CMS Energy and Consumers have worked to integrate a set of safety principles into their business operations and culture. These principles include complying with applicable safety, health, and security regulations and implementing programs and processes aimed at continually improving safety and security conditions. Over the last ten years, Consumers’ OSHA recordable incident rate has decreased by over 70 percent.

CMS Energy and Consumers also place a high priority on customer value and on providing a hometown customer experience. Consumers’ customer-driven investment program is aimed at improving safety and increasing electric and gas reliability, which has resulted in measurable improvements in customer satisfaction.

Central to Consumers’ commitment to its customers are the initiatives it has undertaken to keep electricity and natural gas affordable, including:

• replacement of coal-fueled generation and PPAs with cleaner and more efficient natural gas‑fueled generation, renewable energy, and energy waste reduction and demand response programs

• targeted infrastructure investment, including the installation of smart meters

• information and control system efficiencies

• employee and retiree health care cost sharing

• workforce productivity enhancements

In addition, Consumers’ gas commodity costs declined by 60 percent from 2008 through 2018, due not only to a decrease in market prices but also to Consumers’ improvements to its gas infrastructure and optimization of its gas purchasing and storage strategy. These gas commodity savings are passed on to customers.

Planet: The planet element of the triple bottom line represents CMS Energy’s and Consumers’ commitment to protect the environment; this commitment extends beyond complying with the various state and federal environmental and health and safety laws and regulations to which CMS Energy and

13

Consumers are subject. Management considers climate change risk and other environmental risks in the companies’ strategy development, business planning, and enterprise risk management processes. In November 2018, CMS Energy published a climate assessment report of the long-term impacts on the company’s portfolio, of public policies and technological advances that are consistent with limiting global warming to no more than two degrees Celsius over pre-industrial levels.

CMS Energy and Consumers continue to focus on opportunities to protect the environment and to reduce their carbon footprint. As a result of actions already taken by CMS Energy and Consumers, including the retirement of seven of Consumers’ coal-fueled electric generating units in 2016, the companies have:

• decreased their combined percentage of electric supply (self-generated and purchased) from coal by 18 percentage points since 2015

• reduced carbon dioxide emissions by over 35 percent since 2005

• reduced the amount of water used to generate electricity by over 30 percent since 2012

• reduced landfill waste disposal by over one million cubic yards since 1992

• reduced methane emissions by 15 percent since 2011

Additionally, over the last 20 years, Consumers has reduced its sulfur dioxide, nitrogen oxide, particulate matter, and mercury emissions by 90 percent.

The 2016 Energy Law:

• raised the renewable energy standard from the present ten‑percent requirement to 12.5 percent in 2019 and 15 percent in 2021

• established a goal of 35 percent combined renewable energy and energy waste reduction by 2025

• authorized incentives for demand response programs and expanded existing incentives for energy efficiency programs, referring to the combined initiatives as energy waste reduction programs

• established an integrated planning process for new generation resources

Consumers filed an IRP with the MPSC in June 2018, detailing its long‑term strategy for delivering reliable and affordable energy to its customers through the increased use of energy efficiency and customer demand management programs and additional renewable energy. In March 2019, Consumers and a broad coalition of key stakeholders, including the MPSC Staff and the Michigan Attorney General, filed a settlement agreement with the MPSC resolving Consumers’ IRP. In April 2019, two parties filed objections to the settlement agreement. The MPSC has commenced a contested settlement proceeding to determine whether the agreement is reasonable and in the public interest, and will either approve or reject the settlement by June 10, 2019.

In its IRP, Consumers details how it will meet the requirements of the 2016 Energy Law using its clean and lean strategy, which focuses on increasing the generation of renewable energy, helping customers use less energy, and offering demand response programs to reduce demand during critical peak times. Further, Consumers details its plans to replace all of its coal-fueled generation with investment in renewable energy, which will enable Consumers to meet and exceed the 2016 Energy Law renewable energy requirements and fulfill increasing customer demand for renewable energy. The IRP would reduce carbon emissions by more than 90 percent by 2040, surpassing the breakthrough goal Consumers set in 2018 to reduce carbon emissions by 80 percent. Additionally, the IRP would allow Consumers to achieve a breakthrough goal of at least 50 percent combined renewable energy and energy waste reduction by 2030.

14

Additionally, in an effort to advance its environmental stewardship in Michigan and to minimize the impact of future regulations, Consumers announced the following five-year targets during 2018:

• to reduce its water use by one billion gallons; in 2018, Consumers reduced its water usage by 180 million gallons

• to reduce the amount of waste taken to landfills by 35 percent; in 2018, Consumers reduced its waste to landfills by 12 percent

• to enhance, restore, or protect 5,000 acres of land; in 2018, Consumers enhanced, restored, or protected nearly 800 acres of land

CMS Energy, through its non-utility businesses, continues to pursue further opportunities for the development of renewable generation projects. CMS Enterprises has completed the development of and operates a 105‑MW wind generation project in northwest Ohio and three solar generation projects in Michigan and Wisconsin totaling 27 MW. Renewable energy produced by these projects is committed to customers under long-term PPAs.

CMS Energy and Consumers are monitoring numerous legislative, policy, and regulatory initiatives, including those to regulate greenhouse gases, and related litigation. While CMS Energy and Consumers cannot predict the outcome of these matters, which could have a material effect on the companies, they intend to continue to move forward with their clean and lean strategy.

Profit: The profit element of the triple bottom line represents CMS Energy’s and Consumers’ commitment to meeting financial objectives and providing economic development opportunities and benefits in the communities in which they do business. CMS Energy’s and Consumers’ financial strength allows them to maintain solid investment-grade credit ratings and thereby reduce funding costs for the benefit of customers and investors, to preserve and create jobs, and to reinvest in the communities they serve.

For the three months ended March 31, 2019, CMS Energy’s net income available to common stockholders was $213 million, and diluted EPS were $0.75. This compares with net income available to common stockholders of $241 million and diluted EPS of $0.86 for the three months ended March 31, 2018. In 2019, the benefits from electric and gas rate increases and higher sales were more than offset by higher service restoration costs from 2019 winter storms, higher depreciation, and lower earnings at the enterprises segment. A more detailed discussion of the factors affecting CMS Energy’s and Consumers’ performance can be found in the Results of Operations section that follows this Executive Overview.

Consumers projects that its electric weather-normalized deliveries will remain stable and gas weather‑normalized deliveries will increase slightly through 2023. This outlook reflects modest growth in electric demand offset by the effects of energy waste reduction programs, and modest growth in gas demand offset partially by energy efficiency and conservation.

15

Performance: Impacting the Triple Bottom Line

CMS Energy and Consumers remain committed to achieving world class performance while delivering hometown service. Leveraging the Consumers Energy Way, CMS Energy and Consumers accomplished the following during 2018:

• achieved record-breaking performance in the area of on-time delivery commitments

• attracted 101 MW of new or expanding load in Consumers’ service territory

• announced clean energy goals and filed an IRP in support of those goals

• expanded CMS Enterprises’ renewable portfolio

• enhanced or restored nearly 800 acres of land in Michigan

• finished first overall across the electric utility sector in cyber security testing

CMS Energy and Consumers will continue to utilize the Consumers Energy Way to enable them to achieve world class performance and positively impact the triple bottom line. Consumers’ investment plan and the regulatory environment in which it operates also drive its ability to impact the triple bottom line.

Investment Plan: Consumers expects to make significant expenditures on infrastructure upgrades and replacements and electric supply projects from 2019 through 2023. While it has a large number of potential investment opportunities that would add customer value, Consumers has prioritized its spending based on the criteria of enhancing public safety, increasing reliability, maintaining affordability for its customers, and advancing its environmental stewardship. Consumers’ investment program is expected to result in annual rate-base growth of six to eight percent. This rate-base growth, together with cost-control initiatives, should allow Consumers to maintain affordable customer prices.

Presented in the following illustration are planned capital expenditures of $11.2 billion that Consumers expects to make from 2019 through 2023:

16

Consumers plans to spend $9.3 billion over the next five years to maintain and upgrade its gas infrastructure and electric distribution systems in order to enhance safety and reliability, improve customer satisfaction, and reduce energy waste on those systems. The gas infrastructure projects comprise $5.1 billion to sustain deliverability and enhance pipeline integrity and safety. These projects, which involve replacement of mains and services and enhancement of transmission and storage systems, should reduce the minor quantity of methane emissions released as gas is transported. The electric distribution projects comprise $4.2 billion to strengthen circuits and substations and replace poles. Consumers also expects to spend $1.9 billion on electric supply projects, representing new generation, including renewable generation, and environmental investments needed to comply with state and federal laws and regulations.

Regulation: Regulatory matters are a key aspect of Consumers’ business, particularly rate cases and regulatory proceedings before the MPSC, which permit recovery of new investments while helping to ensure that customer rates are fair and affordable. Important regulatory events and developments not already discussed are summarized below.

• 2018 Electric Rate Case: In May 2018, Consumers filed an application with the MPSC seeking an annual rate increase of $58 million, based on a 10.75 percent authorized return on equity. The filing requested authority to recover new investment in system reliability, environmental compliance, and technology enhancements. In October 2018, Consumers reduced its requested annual rate increase to $44 million. In January 2019, the MPSC approved a settlement agreement authorizing an annual rate decrease of $24 million, based on a 10.0 percent authorized return of equity. With the elimination of the $113 million TCJA credit to customer bills, the approved settlement agreement results in an $89 million net increase in annual rates. The settlement agreement also provides for deferred accounting treatment for distribution‑related capital investments exceeding certain amounts. Consumers also agreed to not file a new electric rate case prior to January 2020.

• 2018 Gas Rate Case:In November 2018, Consumers filed an application with the MPSC seeking an annual rate increase of $229 million, based on a 10.75 percent authorized return on equity.The filing also seeks approval of two rate adjustment mechanisms: a revenue decoupling mechanism and an investment recovery mechanism. The revenue decoupling mechanism would annually reconcile Consumers’ actual weather‑normalized non‑fuel revenues with the revenues approved by the MPSC. The investment recovery mechanism would provide for additional annual rate increases of $11 million beginning in October 2020 and another $11 million beginning in October 2021 for incremental investments that Consumers plans to make in those years, subject to reconciliation. These future investments are intended to help ensure adequate system capacity and deliverability.

• Tax Cuts and Jobs Act: The TCJA, which changed existing federal tax law and included numerous provisions that affect businesses, was signed into law in December 2017. In early 2018, the MPSC ordered Consumers to file various proceedings to determine the reduction in its electric and gas revenue requirements as a result of the reduction in the corporate income tax rate, and to implement bill credits to reflect that reduction until customer rates could be adjusted through Consumers’ general rate cases. Consumers filed, and the MPSC approved, such proceedings throughout 2018, resulting in credits to customer bills during 2018 to reflect reductions in Consumers’ electric and gas revenue requirements. Additionally, Consumers filed an application to address the December 31, 2017 remeasurement of its deferred income taxes and other base rate impacts of the TCJA on customers. For details on these proceedings, see Note 2, Regulatory Matters.

Looking Forward

CMS Energy and Consumers will continue to consider the impact on the triple bottom line of people, planet, and profit in their daily operations as well as in their long-term strategic decisions. Consumers will continue to seek fair and timely regulatory treatment that will support its customer-driven investment plan, while pursuing cost-control initiatives that will allow it to maintain sustainable customer base rates. The Consumers Energy Way is an important means of realizing CMS Energy’s and Consumers’ purpose of achieving world class performance while delivering hometown service.

Consumers Electric Utility Results of Operations

For the three months ended March 31, 2019, Consumers electric utility’s net income available to common stockholders was $105 million. This compares with net income available to common stockholders of $139 million for the three months ended March 31, 2018. In 2019, revenues were higher due to the impact of the rate order implemented in January 2019 and favorable sales mix. These increases were more than offset by higher service restoration costs resulting from significant 2019 winter storms and costs associated with higher capital spending. Presented in the following table are the detailed changes to the electric utility’s net income available to common stockholders for the three months ended March 31, 2019 versus 2018:

Capital Resources and Liquidity

CMS Energy uses dividends and tax‑sharing payments from its subsidiaries and external financing and capital transactions to invest in its utility and non‑utility businesses, retire debt, pay dividends, and fund its other obligations. The ability of CMS Energy’s subsidiaries, including Consumers, to pay dividends to CMS Energy depends upon each subsidiary’s revenues, earnings, cash needs, and other factors. In addition, Consumers’ ability to pay dividends is restricted by certain terms included in its debt covenants and articles of incorporation and potentially by FERC requirements and provisions under the Federal Power Act and the Natural Gas Act. For additional details on Consumers’ dividend restrictions, see Note 4, Financings and Capitalization—Dividend Restrictions. For the three months ended March 31, 2019, Consumers paid $172 million in dividends on its common stock to CMS Energy.

As a result of a provision in the TCJA, CMS Energy is required to recover all alternative minimum tax credits over four years through offsets of regular tax and through cash refunds. CMS Energy expects to be able to offset regular tax through the use of federal net operating loss carryforwards and, accordingly, receive alternative minimum tax credit refunds through 2021. Another provision in the TCJA excludes rate‑regulated utilities from 100 percent cost expensing of certain property. This provision will cause Consumers to make higher tax‑sharing payments to CMS Energy, which in turn might permit CMS Energy to maintain lower levels of debt in order to invest in its businesses, pay dividends, and fund its general obligations. Consumers expects to have sufficient funding sources available to issue credits to customers for all impacts of the TCJA.

24

In 2018, CMS Energy entered into an equity offering program under which it may sell, from time to time, shares of CMS Energy common stock having an aggregate sales price of up to $250 million. Under this program, CMS Energy may sell its common stock in privately negotiated transactions, in “at the market” offerings, through forward sales transactions or otherwise. As of March 31, 2019, CMS Energy had entered into forward sales contracts having an aggregate sales price of $250 million. These contracts allow CMS Energy to either physically settle the contracts by issuing shares of its common stock at the then‑applicable forward sale price specified by the agreement or net settle the contracts through the delivery or receipt of cash or shares. CMS Energy may settle the contracts at any time through their maturity dates, and presently intends to physically settle the contracts by delivering shares of its common stock. For more information on the forward sale contracts, see Note 4, Financings and Capitalization.

Consumers uses cash flows generated from operations and external financing transactions, as well as stockholder contributions from CMS Energy, to fund capital expenditures, retire debt, pay dividends, contribute to its employee benefit plans, and fund its other obligations. Accelerated pension funding in prior years and several initiatives to reduce costs have helped improve cash flows from operating activities. Consumers anticipates continued strong cash flows from operating activities for 2019 and beyond.

Access to the financial and capital markets depends on CMS Energy’s and Consumers’ credit ratings and on market conditions. As evidenced by past financing transactions, CMS Energy and Consumers have had ready access to these markets. Barring major market dislocations or disruptions, CMS Energy and Consumers expect to continue to have ready access to the financial and capital markets. If access to these markets were to diminish or otherwise become restricted, CMS Energy and Consumers would implement contingency plans to address debt maturities, which could include reduced capital spending.

At March 31, 2019, CMS Energy had $546 million of its revolving credit facility available and Consumers had $1,078 million available under its revolving credit facilities. CMS Energy and Consumers use these credit facilities for general working capital purposes and to issue letters of credit. An additional source of liquidity is Consumers’ commercial paper program, which allows Consumers to issue, in one or more placements, up to $500 million in the aggregate in commercial paper notes with maturities of up to 365 days and that bear interest at fixed or floating rates. These issuances are supported by Consumers’ revolving credit facilities. While the amount of outstanding commercial paper does not reduce the available capacity of the revolving credit facilities, Consumers does not intend to issue commercial paper in an amount exceeding the available capacity of the facilities. At March 31, 2019, $30 million of commercial paper notes were outstanding under this program. For additional details on CMS Energy’s and Consumers’ revolving credit facilities and commercial paper program, see Note 4, Financings and Capitalization.

Certain of CMS Energy’s and Consumers’ credit agreements, debt indentures, and other facilities contain covenants that require CMS Energy and Consumers to maintain certain financial ratios, as defined therein. At March 31, 2019, no default had occurred with respect to any financial covenants contained in CMS Energy’s and Consumers’ credit agreements, debt indentures, or other facilities. CMS Energy and Consumers were each in compliance with these covenants as of March 31, 2019, as presented in the following table:

	March 31, 2019
Credit Agreement, Indenture, or Facility	Limit		Actual
CMS Energy, parent only
Debt to EBITDA1	<	6.25 to 1.0	4.4 to 1.0
Consumers
Debt to Capital2	<	0.65 to 1.0	0.47 to 1.0

¹  Applies to CMS Energy’s $550 million revolving credit agreement.

²  Applies to Consumers’ $850 million and $250 million revolving credit agreements and its $35 million and $30 million reimbursement agreements.

Components of CMS Energy’s and Consumers’ cash management plan include controlling operating expenses and capital expenditures and evaluating market conditions for financing and refinancing opportunities. CMS Energy’s and Consumers’ present level of cash and expected cash flows from operating activities, together with access to sources of liquidity, are anticipated to be sufficient to fund the companies’ contractual obligations for 2019 and beyond.

Off‑Balance‑Sheet Arrangements

CMS Energy, Consumers, and certain of their subsidiaries enter into various arrangements in the normal course of business to facilitate commercial transactions with third parties. These arrangements include indemnities, surety bonds, letters of credit, and financial and performance guarantees. Indemnities are usually agreements to reimburse a counterparty that may incur losses due to outside claims or breach of contract terms. The maximum payment that could be required under a number of these indemnity obligations is not estimable; the maximum obligation under indemnities for which such amounts were estimable was $153 million at March 31, 2019. While CMS Energy and Consumers believe it is unlikely that they will incur any material losses related to indemnities they have not recorded as liabilities, they cannot predict the impact of these contingent obligations on their liquidity and financial condition. For additional details on these and other guarantee arrangements, see Note 3, Contingencies and Commitments—Guarantees.

Outlook

Several business trends and uncertainties may affect CMS Energy’s and Consumers’ financial condition and results of operations. These trends and uncertainties could have a material impact on CMS Energy’s and Consumers’ consolidated income, cash flows, or financial position. For additional details regarding these and other uncertainties, see Forward-Looking Statements and Information; Note 2, Regulatory Matters; Note 3, Contingencies and Commitments; and Part II—Item 1A. Risk Factors.

Consumers Electric Utility Outlook and Uncertainties

Energy Resource Planning: While Consumers continues to experience modest growth in demand for electricity due to Michigan’s growing economy and increased use of air conditioning, consumer electronics, and other electric devices, it expects that increase in demand to be offset by the effects of energy efficiency and conservation.

In June 2018, Consumers filed an IRP with the MPSC detailing its long‑term strategy for delivering reliable and affordable energy to its customers through the increased use of energy efficiency and customer demand management programs and additional renewable energy. In March 2019, Consumers and a broad coalition of key stakeholders, including the MPSC Staff and the Michigan Attorney General, filed a settlement agreement with the MPSC resolving Consumers’ IRP. In April 2019, two parties filed objections to the settlement agreement. The MPSC has commenced a contested settlement proceeding to determine whether the agreement is reasonable and in the public interest, and will either approve or reject the settlement by June 10, 2019.

26

The settlement agreement allows Consumers to reduce carbon emissions by more than 90 percent by 2040 and eliminate the use of coal to generate electricity by 2040. Specifically, the parties agreed to:

• the retirement of two coal‑fueled generating units, totaling 515 MW, in 2023

• the continued assessment in future IRP filings concerning the retirement of two coal‑fueled generating units, totaling 608 MW

The settlement agreement provides that Consumers will replace the capacity to be retired with:

• increased demand response programs

• increased energy efficiency

• increased renewable energy generation

• conservation voltage reduction

The settlement agreement requires that Consumers competitively bid new capacity, and that at least 50 percent of the new capacity be built and owned by third parties; the remainder will be owned and operated by Consumers. In accordance with the 2016 Energy Law, the parties to the IRP settlement agreement also agreed to enable Consumers to earn a financial incentive on PPAs approved by the MPSC after January 1, 2019.

The settlement agreement also allows for recovery of significant increases in demand response costs and requires that Consumers file a new IRP by June 2021.

PURPA: PURPA requires Consumers to purchase power from qualifying cogeneration and small power production facilities at a price approved by the MPSC that is meant to represent Consumers’ “avoided cost” of generating power or purchasing power from another source. In November 2017, the MPSC issued an order establishing a new avoided‑cost methodology for determining the price that Consumers must pay to purchase power under PURPA. Among other things, the MPSC’s order changes the basis of Consumers’ avoided cost from the cost of coal‑fueled generating units to that of natural gas‑fueled generating units. The MPSC order also assigns more capacity value to qualifying facilities that are consistently able to generate electricity during peak times. Although the costs Consumers incurs to purchase power from qualifying facilities are passed on to customers, the order could result in mandated purchases of generation, potentially at above‑market prices, and reduce Consumers’ need for new owned generation. This in turn could have a material adverse effect on Consumers’ capital investment plan and the affordability of future customer rates.

In December 2017, Consumers filed a petition with the MPSC requesting corrections to the pricing calculations and capacity purchase model set in the order. Subsequently, the MPSC suspended the implementation of the order and reopened the proceeding. In February 2018, the MPSC issued an order limiting Consumers’ obligation to pay the full avoided capacity cost, which is based on the cost of a natural gas combustion turbine under the new avoided‑cost formula, to existing qualifying facilities upon the expiration of outstanding contracts and to the first 150 MW of new generation projects that qualify under PURPA. In October 2018, the MPSC issued an order lifting the suspension on the November 2017 order and thereby making effective the avoided‑cost formula set at that time. According to the October 2018 order, the use of the full avoided‑cost formula is still limited to outstanding contracts that expire and the first 150 MW of new qualifying generation projects. The October 2018 order also provides that all other qualifying generation projects that establish a legally enforceable obligation are eligible to receive a capacity payment equal to the MISO planning resource auction price and a designated energy price approved in the MPSC’s October order. The MPSC also ruled that the determination of Consumers’ future capacity needs shall take place in the IRP proceeding that Consumers filed in June 2018. Consumers filed a complaint with the MPSC challenging the rates approved in the October 2018 order.  Two developers representing approximately 2,000 MW of qualifying generation projects have filed

27

complaints with the MPSC claiming that their projects have legally enforceable obligations making them eligible for the avoided cost rates approved in the October 2018 order.

In the IRP settlement agreement filed with the MPSC, Consumers and other stakeholders agreed to a new method of calculating avoided cost, based on a competitive bidding process that will enable Consumers to purchase energy from new generation at the lowest cost and mitigate the risk of forced purchases of unneeded renewable generation. Consumers cannot predict the outcome of these matters.

Renewable Energy Plan: The 2016 Energy Law raised the renewable energy standard from the present ten‑percent requirement to 15 percent in 2021, with an interim target of 12.5 percent in 2019. Consumers is required to submit RECs, which represent proof that the associated electricity was generated from a renewable energy resource, in an amount equal to at least the required percentage of Consumers’ electric sales volume each year. Under its renewable energy plan, Consumers expects to meet its renewable energy requirement each year with a combination of newly generated RECs and previously generated RECs carried over from prior years.

In conjunction with its renewable energy plan, Consumers began construction in 2017 of Cross Winds^®Energy Park Phase III, with a planned nameplate capacity of 76 MW, and expects it to be operational in 2020. This project is expected to qualify for certain federal production tax credits, generating cost savings that will be passed on to customers.

In February 2019, the MPSC issued an order ruling on amendments Consumers had requested to its renewable energy plan. The MPSC approved the acquisition of up to 525 MW of new wind generation projects, but ruled that Consumers’ request to acquire up to 100 MW of new solar generation will be addressed in a separate proceeding. The MPSC also approved an agreement under which Consumers will purchase a wind generation project under development, with capacity of up to 150 MW, in Gratiot County, Michigan. Consumers expects to begin construction of this project in September 2019 and that it will be complete and operational in 2020.

In June 2018, Consumers issued a request for proposals to acquire up to 400 MW of wind generation projects ranging in size from 75 MW to 200 MW and up to 100 MW of solar generation projects at least 10 MW in size. The projects are required to be located in Michigan and operational by 2021. Negotiations are in progress with several bidders. Any contracts entered into as a result of the request for proposals would be subject to MPSC approval.

Electric Customer Deliveries and Revenue: Consumers’ electric customer deliveries are seasonal and largely dependent on Michigan’s economy. The consumption of electric energy typically increases in the summer months, due primarily to the use of air conditioners and other cooling equipment. In addition, Consumers’ electric rates, which follow a seasonal rate design, are higher in the summer months than in the remaining months of the year.

Consumers expects weather‑normalized electric deliveries over the next five years to remain stable relative to 2018. This outlook reflects modest growth in electric demand offset by the effects of energy waste reduction programs and appliance efficiency standards. Actual delivery levels will depend on:

• energy conservation measures and results of energy waste reduction programs

• weather fluctuations

• Michigan’s economic conditions, including utilization, expansion, or contraction of manufacturing facilities, population trends, and housing activity

Electric ROA: Michigan law allows electric customers in Consumers’ service territory to buy electric generation service from alternative electric suppliers in an aggregate amount capped at ten percent, with

28

certain exceptions, of Consumers’ weather‑normalized retail sales of the preceding calendar year. At March 31, 2019, electric deliveries under the ROA program were at the ten‑percent limit. Of Consumers’ 1.8 million electric customers, 286 customers, or 0.02 percent, purchased electric generation service under the ROA program.

The 2016 Energy Law established a path to ensure that forward capacity is secured for all electric customers in Michigan, including customers served by alternative electric suppliers under ROA. The new law also authorized the MPSC to ensure that alternative electric suppliers have procured enough capacity to cover their anticipated capacity requirements for the four‑year forward period. In 2017, the MPSC issued an order establishing a state reliability mechanism for Consumers. Under this mechanism, beginning June 1, 2018, if an alternative electric supplier does not demonstrate that it has procured its capacity requirements for the four‑year forward period, its customers will pay a set charge to the utility for capacity that is not provided by the alternative electric supplier. All alternative electric suppliers have demonstrated that they have procured their capacity requirements through the MISO planning year beginning June 1, 2022.

In June 2018, the MPSC issued an order requiring all electric suppliers to demonstrate that a portion of the capacity procured to serve customers during peak demand times is located in the MISO footprint in Michigan’s Lower Peninsula. In July 2018, the Michigan Court of Appeals issued a decision that the MPSC does not have statutory authority to implement such a requirement for alternative electric suppliers. Consumers believes the 2016 Energy Law does give such authorization to the MPSC. The MPSC and Consumers have filed applications for leave to appeal the Court of Appeals’ decision to the Michigan Supreme Court. The Michigan Supreme Court has discretion on whether to grant the applications for leave to appeal.

Electric Rate Matters: Rate matters are critical to Consumers’ electric utility business. For additional details on rate matters, see Note 2, Regulatory Matters.

Electric Environmental Outlook: Consumers’ operations are subject to various state and federal environmental laws and regulations. Consumers estimates that it will incur capital expenditures of $0.3 billion from 2019 through 2023 to continue to comply with RCRA, the Clean Water Act, the Clean Air Act, and numerous state and federal environmental regulations. Consumers expects to recover these costs in customer rates, but cannot guarantee this result. Consumers’ primary environmental compliance focus includes, but is not limited to, the following matters.

Air Quality: Multiple air quality regulations apply, or may apply, to Consumers.

CSAPR, which became effective in 2015, requires Michigan and many other states to improve air quality by reducing power plant emissions that, according to EPA computer models, contribute to ground‑level ozone and fine particle pollution in other downwind states. In 2016, the EPA finalized new ozone season standards for CSAPR, which became effective in 2017. CSAPR is presently being litigated; however, any decision will not impact Consumers’ compliance strategy, as Consumers expects its emissions to be within the CSAPR allowance allocations.

In 2012, the EPA published emission standards for electric generating units, based on Section 112 of the Clean Air Act, known as MATS. Under MATS, all of Consumers’ existing coal‑fueled electric generating units were required to add additional controls for hazardous air pollutants. Consumers met the extended deadline of April 2016 for five coal‑fueled units and two oil/gas‑fueled units it continues to operate and retired its seven remaining coal‑fueled units. MATS is presently being litigated. In addition, in December 2018, the EPA proposed changes to the supporting analysis used to justify MATS, but did not propose any changes to the MATS regulations. Any changes resulting from that litigation or rulemaking are not expected to impact Consumers’ MATS compliance strategy because Consumers is still required to

29

comply with the Michigan Mercury Rule, which has similar requirements to MATS. In addition, Consumers must comply with its settlement agreement with the EPA entered into in 2014 concerning opacity and NSR.

In 2015, the EPA released its new rule to lower the NAAQS for ozone. The new ozone NAAQS will make it more difficult to construct or modify power plants in areas of the country that have not met the new ozone standard. In April 2018, the EPA designated certain areas of Michigan as not meeting the new standard with an August 2018 effective date. None of Consumers’ fossil‑fuel‑fired generating units are located in these areas. Some of Consumers’ compressor stations are located in areas impacted by the rule, but Consumers expects only minor permitting impacts if those units are modified in the future. The NAAQS for ozone are presently being litigated. Consumers does not expect that any decision will have a material adverse impact on its generating assets.

Consumers’ strategy to comply with air quality regulations, including CSAPR, NAAQS, and MATS, as well as its legal obligations, involved the installation and operation of emission control equipment at some facilities and the suspension of operations at others; however, Consumers continues to evaluate these rules in conjunction with other EPA and MDEQ rulemakings, litigation, and congressional action. This evaluation could result in:

• a change in Consumers’ fuel mix

• changes in the types of generating units Consumers may purchase or build in the future

• changes in how certain units are used

• the retirement, mothballing, or repowering with an alternative fuel of some of Consumers’ generating units

• changes in Consumers’ environmental compliance costs

Greenhouse Gases: There have been numerous legislative and regulatory initiatives at the state, regional, national, and international levels that involve the potential regulation of greenhouse gases. Consumers continues to monitor and comment on these initiatives and to follow litigation involving greenhouse gases.

In 2015, the EPA finalized new rules pursuant to Section 111(b) of the Clean Air Act to limit carbon dioxide emissions from new electric generating units, as well as modified or reconstructed electric generating units. New coal‑fueled units would not be able to meet this limit without installing carbon dioxide control equipment using such methods as carbon capture and sequestration. These rules are being litigated.

In December 2018, the EPA proposed a revised Section 111(b) regulation to replace the 2015 standard rule limiting carbon dioxide emissions from new electric generating units, citing limited availability and high costs of carbon capture and sequestration equipment as reasons to change the 2015 rule. The revised Section 111(b) regulation requires new coal‑fueled generating units to meet a highly efficient steam cycle performance standard. Consumers does not expect this proposal to change its existing environmental strategy.

Also in 2015, the EPA published final rules pursuant to Section 111(d) of the Clean Air Act to limit carbon dioxide emissions from existing electric generating units, calling the rules the “Clean Power Plan.” The rules required a 32‑percent nationwide reduction in carbon emissions from existing power plants by 2030 (based on 2005 levels). States choosing not to develop their own implementation plans would be subject to the federal plan. Certain states, corporations, and industry groups initiated litigation opposing the proposed Clean Power Plan, and in 2016, the U.S. Supreme Court stayed the Clean Power Plan while the litigation proceeded. In March 2017, the EPA and other federal agencies were directed to review the Clean Power Plan, among other proposed or final rules. The EPA subsequently filed motions to hold the

30

Section 111(b) and Clean Power Plan litigation in abeyance while it reconsidered the rules. In October 2017, the EPA published a proposal to repeal the Clean Power Plan and is reviewing comments received.

In August 2018, the EPA proposed the “Affordable Clean Energy” rule as a replacement for the EPA’s 2015 Clean Power Plan, which the U.S. Supreme Court stayed in 2016. This proposed rule requires individual states to evaluate fossil fuel‑fired power plants for heat‑rate improvements that could increase overall plant efficiency. There is also a proposal to modify the Clean Air Act permitting requirements to promote these efficiency projects. The EPA believes it will finalize the Affordable Clean Energy rule in 2019. Consumers does not expect that the Affordable Clean Energy rule will have an adverse impact on its environmental strategy.

In 2015, a group of 195 countries, including the U.S., finalized the Paris Agreement, which governs carbon dioxide reduction measures beginning in 2020. Although the U.S. subsequently withdrew from the Paris Agreement, it has stated a desire to renegotiate a new agreement in the future. At this time, Consumers does not expect any adverse changes to its environmental strategy as a result of these events.

While Consumers cannot predict the outcome of changes in U.S. policy or of other legislative or regulatory initiatives involving the potential regulation of greenhouse gases, it intends to continue to move forward with its clean energy plan, its present carbon reduction goal, and its emphasis on supply diversity. Consumers will continue to monitor regulatory and legislative activity and related litigation regarding greenhouse gas emissions standards that may affect electric generating units.

Severe weather events and climate change associated with increasing levels of greenhouse gases could affect the companies’ facilities and energy sales and could have a material impact on the companies’ future results of operations. Consumers is unable to predict these events or their financial impact; however, Consumers plans for adverse weather and takes steps to reduce its potential impact.

Litigation, international treaties, federal laws and regulations (including regulations by the EPA), and state laws and regulations, if enacted or ratified, could ultimately require Consumers to replace equipment, install additional emission control equipment, purchase emission allowances, curtail operations, arrange for alternative sources of supply, mothball or retire facilities that generate certain emissions, or take other steps to manage or lower the emission of greenhouse gases. Although associated capital or operating costs relating to greenhouse gas regulation or legislation could be material and cost recovery cannot be assured, Consumers expects to recover these costs and capital expenditures in rates consistent with the recovery of other reasonable costs of complying with environmental laws and regulations.

CCRs: In 2015, the EPA published a final rule regulating CCRs, such as coal ash, under RCRA. The final rule adopts minimum standards for beneficially reusing and disposing of non‑hazardous CCRs. The rule establishes new minimum requirements for site location, groundwater monitoring, flood protection, storm water design, fugitive dust control, and public disclosure of information, including any groundwater protection standard exceedances. The rule also sets out conditions under which CCR units would be forced to cease receiving CCR and non‑CCR waste and initiate closure based on the inability to achieve minimum safety standards, meet a location standard, or meet minimum groundwater standards. Consumers has aligned with state regulatory authorities on closure plans for each of its unlined ash ponds to ensure coordination between federal and state requirements. Work has already been completed to close some existing ash ponds and replace them with double‑lined ash ponds or concrete tanks.

Furthermore, Congress passed legislation in 2016 that allows participating states to develop permitting programs for CCRs under RCRA. In July 2018, the EPA published preliminary rulemaking that was intended to amend the 2015 final rule. The rulemaking did not change Consumers’ compliance strategy, but demonstrated the EPA’s willingness to allow states to incorporate flexibility into their permitting

31

processes. Consumers is waiting for the EPA to promulgate a final rule. In December 2018, Michigan adopted a permitting program, which would still require the EPA’s authorization. The MDEQ is presently working on an application requesting such authorization for the Michigan permitting program. Federal rulemaking delays also have the potential to delay EPA approval of the Michigan permitting program.

Consumers may need to adjust its recorded ARO associated with coal ash disposal sites depending on the outcome of its submissions to the MDEQ and on the RCRA permitting program under the MDEQ, if the EPA approves a state‑level program. Consumers has historically been authorized to recover in electric rates costs related to coal ash disposal sites.

Water: The EPA’s rule to regulate the cooling water intake systems of existing electric generating plants under Section 316(b) of the Clean Water Act became effective in 2014. The rule is aimed at reducing alleged harmful impacts on fish and shellfish. In April 2018, Consumers submitted to the MDEQ for review and approval all required studies and recommended plans to comply with Section 316(b).

In 2015, the EPA released its final effluent limitation guidelines. These guidelines, which are presently being litigated, set stringent new requirements for the discharge from electric generating units into wastewater streams. In August 2017, the EPA announced that it will undertake a rulemaking to replace specific portions of the rule. In September 2017, the EPA proposed delaying the compliance start dates for two years, but maintained the compliance end dates. Consumers expects that additional rulemaking will begin in 2019 and likely conclude in 2020. Consumers does not expect any adverse changes to its environmental strategy as a result of any revisions to the rule.

In 2015, the EPA and the U.S. Army Corps of Engineers published a final rule redefining “waters of the United States,” which defines the scope of the EPA’s jurisdiction under the Clean Water Act. Numerous states and other interested parties have filed suits in federal courts to block the rule, which subsequently was stayed in 2015 while litigation ensued. In January 2018, the U.S. Supreme Court unanimously ruled that the federal district courts, not the federal appellate courts, had jurisdiction over challenges to the 2015 rule. Consequently, in February 2018, the U.S. Court of Appeals for the Sixth Circuit lifted the stay of the rule. The EPA has published a notice, called the Applicability Rule, that prevents the 2015 rule from going into effect until February 2020 in an attempt to maintain consistency and provide certainty for regulated entities while the agencies continue to consider possible revisions to the 2015 rule. In August 2018, the U.S. District Court for the District of South Carolina set aside the Applicability Rule nationally and, as a result, the 2015 rule again went into effect in 22 states, including Michigan.

In December 2018, the EPA and the U.S. Army Corps of Engineers released a proposed rule re‑defining the term “waters of the United States” under the Clean Water Act. In 2015, the EPA under President Obama approved a rule expanding the definition, particularly with respect to tributaries, adjacent waters, and wetlands. The EPA’s recently proposed rule narrows the definition of jurisdictional waters.

The 2015 and 2018 rules change the scope of water and wetlands regulations for the EPA under the Clean Water Act. The EPA has delegated authority to manage the Michigan wetlands program to the MDEQ. As a result, regardless of the 2015 and 2018 rules’ ultimate outcome, Consumers expects to continue to operate under Michigan’s wetlands regulations, and under the applicable state and federal water jurisdictional regulations. Thus, Consumers does not expect any adverse changes to its environmental strategy as a result of these events.

Many of Consumers’ facilities maintain NPDES permits, which are renewed every five years and are vital to the facilities’ operations. Failure of the MDEQ to renew any NPDES permit, a successful appeal against a permit, or onerous terms contained in a permit could have a significant detrimental effect on the operations of a facility.

Other Matters: Other electric environmental matters could have a material impact on Consumers’ outlook. For additional details on other electric environmental matters, see Note 3, Contingencies and Commitments—Consumers Electric Utility Contingencies—Electric Environmental Matters.

Consumers Gas Utility Outlook and Uncertainties

Gas Deliveries: Consumers’ gas customer deliveries are seasonal. The peak demand for natural gas typically occurs in the winter due to colder temperatures and the resulting use of natural gas as heating fuel. Consumers expects weather‑normalized gas deliveries over the next five years to increase slightly relative to 2018. This outlook reflects modest growth in gas demand offset partially by the predicted effects of energy efficiency and conservation. Actual delivery levels from year to year may vary from this expectation due to:

• weather fluctuations

• use by power producers

• availability and development of renewable energy sources

• gas price changes

• Michigan economic conditions, including population trends and housing activity

• the price of competing energy sources or fuels

• energy efficiency and conservation impacts

Gas Rate Matters: Rate matters are critical to Consumers’ gas utility business. For additional details on rate matters, see Note 2, Regulatory Matters.

Gas Rate Case: In November 2018, Consumers filed an application with the MPSC seeking an annual rate increase of $229 million, based on a 10.75 percent authorized return on equity.The filing requests authority to recover new infrastructure investment and related costs that will allow Consumers to improve system safety, capacity, and deliverability. Presented in the following table are the components of the requested increase in revenue:

In Millions
Components of the requested rate increase
Investment in rate base	$	136
Operating and maintenance cost	81
Cost of capital	29
Working capital	11
Gross margin	(28		)
Total	$	229

The filing also seeks approval of two rate adjustment mechanisms: a revenue decoupling mechanism and an investment recovery mechanism. The revenue decoupling mechanism would annually reconcile Consumers’ actual weather‑normalized non‑fuel revenues with the revenues approved by the MPSC. The investment recovery mechanism would provide for additional annual rate increases of $11 million beginning in October 2020 and another $11 million beginning in October 2021 for incremental investments that Consumers plans to make in those years, subject to reconciliation. These future investments are intended to help ensure adequate system capacity and deliverability.

Gas Pipeline and Storage Integrity and Safety: In 2016, PHMSA published a notice of proposed rulemaking that would expand federal safety standards for gas transmission pipelines. The rule could cause Consumers to incur increased capital costs to install and remediate pipelines as well as operating

33

and maintenance costs to expand inspections, maintenance, and monitoring of its existing pipelines. PHMSA expects to publish a final rule in 2019.

Also in 2016, PHMSA published an interim final rule that established minimum federal safety standards for underground natural gas storage facilities. As published, the rule could cause Consumers to incur increased capital and operating and maintenance costs to expand inspections, maintenance, and monitoring of its underground gas storage facilities. PHMSA expects to publish a final rule in 2019.

Although associated capital or operating and maintenance costs relating to these regulations could be material and cost recovery cannot be assured, Consumers would expect to recover such costs and capital expenditures in rates consistent with the recovery of other reasonable costs of complying with laws and regulations. Consumers will continue to monitor gas safety regulations.

Gas Environmental Outlook: Consumers expects to incur response activity costs at a number of sites, including 23 former MGP sites. For additional details, see Note 3, Contingencies and Commitments—Consumers Gas Utility Contingencies—Gas Environmental Matters.

Consumers Electric Utility and Gas Utility Outlook and Uncertainties

Energy Waste Reduction Plan: The 2016 Energy Law authorized incentives for demand response programs and expanded existing incentives for energy efficiency programs, referring to the combined initiatives as energy waste reduction programs. The 2016 Energy Law:

• extended the requirement to achieve annual reductions of 1.0 percent in customers’ electricity use through 2021 and 0.75 percent in customers’ natural gas use indefinitely

• removed limits on investments under the program and provided for a higher return on those investments; together, these provisions effectively doubled the financial incentives Consumers may earn for exceeding the statutory targets

• established a goal of 35 percent combined renewable energy and energy waste reduction by 2025

Under its energy waste reduction plan, Consumers provides its customers with incentives to reduce usage by offering energy audits, rebates and discounts on purchases of highly efficient appliances, and other incentives and programs.

Enterprises Outlook and Uncertainties

CMS Energy’s primary focus with respect to its enterprises businesses is to maximize the value of generating assets, its share of which represents 1,234 MW of capacity, and to pursue opportunities for the development of renewable generation projects.

The enterprises segment’s assets may be affected by environmental laws and regulations. The new ozone NAAQS will make it more difficult to construct or modify power plants in areas of the country that have not met the new ozone standard. In April 2018, the EPA designated certain areas of Michigan as not meeting the new standard with an August 2018 effective date. The enterprises segment’s DIG plant located in Dearborn, Michigan is in one such area and, as a result, would be subject to additional permitting restrictions in the event of any future modifications. For additional details regarding the new ozone NAAQS, see Consumers Electric Utility Outlook and Uncertainties—Electric Environmental Outlook.

34

Trends, uncertainties, and other matters related to the enterprises segment that could have a material impact on CMS Energy’s consolidated income, cash flows, or financial position include:

• investment in and financial benefits received from renewable energy and energy storage projects

• changes in energy and capacity prices

• changes in commodity prices and interest rates on certain derivative contracts that do not qualify for hedge accounting and must be marked to market through earnings

• changes in various environmental laws, regulations, principles, or practices, or in their interpretation

• the outcome of certain legal proceedings, including gas price reporting litigation

• indemnity and environmental remediation obligations at Bay Harbor, including an inability to renew an NPDES permit in 2020

• obligations related to a tax claim from the government of Equatorial Guinea

• representations, warranties, and indemnities provided by CMS Energy in connection with previous sales of assets

For additional details regarding the enterprises segment’s uncertainties, see Note 3, Contingencies and Commitments.

Other Outlook and Uncertainties

EnerBank: EnerBank is a Utah state‑chartered, FDIC‑insured industrial bank providing primarily unsecured consumer installment loans for financing home improvements. EnerBank represented five percent of CMS Energy’s net assets at March 31, 2019 and five percent of CMS Energy’s net income available to common stockholders for the three months ended March 31, 2019. The carrying value of EnerBank’s loan portfolio was $2.0 billion at March 31, 2019. Its loan portfolio was funded primarily by certificates of deposit of $1.9 billion. The 12‑month rolling average net default rate on loans held by EnerBank was 1.2 percent at March 31, 2019. CMS Energy is required both by law and by contract to provide financial support, including infusing additional capital, to ensure that EnerBank satisfies mandated capital requirements and has sufficient liquidity to operate. With its self‑funding plan, EnerBank has exceeded these requirements historically and exceeded them as of March 31, 2019.

Litigation: CMS Energy, Consumers, and certain of their subsidiaries are named as parties in various litigation matters, as well as in administrative proceedings before various courts and governmental agencies, arising in the ordinary course of business. For additional details regarding these and other legal matters, see Note 2, Regulatory Matters and Note 3, Contingencies and Commitments.

CMS Energy Corporation

Consumers Energy Company

Notes to the Unaudited Consolidated Financial Statements

These interim consolidated financial statements have been prepared by CMS Energy and Consumers in accordance with GAAP for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. As a result, CMS Energy and Consumers have condensed or omitted certain information and note disclosures normally included in consolidated financial statements prepared in accordance with GAAP. CMS Energy and Consumers have reclassified certain prior period amounts to conform to the presentation in the present period and to reflect the implementation of new accounting standards. CMS Energy and Consumers are required to make estimates using assumptions that may affect reported amounts and disclosures; actual results could differ from these estimates. In management’s opinion, the unaudited information contained in this report reflects all adjustments of a normal recurring nature necessary to ensure that CMS Energy’s and Consumers’ financial position, results of operations, and cash flows for the periods presented are fairly stated. The notes to the unaudited consolidated financial statements and the related unaudited consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes contained in the 2018 Form 10‑K. Due to the seasonal nature of CMS Energy’s and Consumers’ operations, the results presented for this interim period are not necessarily indicative of results to be achieved for the fiscal year.

1:    New Accounting Standards

Implementation of New Accounting Standards

ASU 2016‑02, Leases: This standard, which was effective on January 1, 2019 for CMS Energy and Consumers, establishes a new accounting model for leases. The standard requires lessees to recognize lease assets and liabilities on the balance sheet for all leases with a term of more than one year, including operating leases, which were not recorded on the balance sheet under previous standards. The new guidance also amends the definition of a lease to require that a lessee have the right to control the use of a specified asset, and not simply control or take the output of the asset. On the statement of income, operating leases are generally accounted for under a straight-line expense model, while finance leases, which were previously referred to as capital leases, are generally accounted for under a financing model. Consistent with the previous lease guidance, however, the standard allows rate-regulated utilities to recognize expense consistent with the timing of recovery in rates.

CMS Energy and Consumers elected to use certain practical expedients permitted by the standard, under which they were not required to perform lease assessments or reassessments for agreements existing on the effective date. They also elected a transition method under which they initially applied the standard on January 1, 2019, without adjusting amounts presented for prior periods. Under the standard, CMS Energy and Consumers recognized additional lease assets and liabilities on their consolidated balance sheets as of January 1, 2019 for their operating leases. In addition, in accordance with the standard, they have provided additional disclosures about their leases in Note 8, Leases. The standard did not have any impact on CMS Energy’s and Consumers’ consolidated net income or cash flows, and there was no cumulative-effect adjustment recorded to beginning retained earnings.

New Accounting Standards Not Yet Effective

ASU 2016‑13, Measurement of Credit Losses on Financial Instruments: This standard, which will be effective January 1, 2020 for CMS Energy and Consumers, provides new guidance for estimating and

51

recording credit losses on financial instruments. The standard will apply to the recognition of loan losses at EnerBank as well as to the recognition of uncollectible accounts expense at Consumers. Entities will apply the standard using a modified retrospective approach, with a cumulative‑effect adjustment recorded to beginning retained earnings on the effective date. CMS Energy and Consumers are evaluating the impact of the standard on their consolidated financial statements.

2:    Regulatory Matters

Regulatory matters are critical to Consumers. The Michigan Attorney General, ABATE, the MPSC Staff, and certain other parties typically participate in MPSC proceedings concerning Consumers, such as Consumers’ rate cases and PSCR and GCR processes. These parties often challenge various aspects of those proceedings, including the prudence of Consumers’ policies and practices, and seek cost disallowances and other relief. The parties also have appealed significant MPSC orders. Depending upon the specific issues, the outcomes of rate cases and proceedings, including judicial proceedings challenging MPSC orders or other actions, could negatively affect CMS Energy’s and Consumers’ liquidity, financial condition, and results of operations. Consumers cannot predict the outcome of these proceedings.

There are multiple appeals pending that involve various issues concerning cost recovery from customers, the adequacy of the record evidence supporting the recovery of Smart Energy investments, and other matters. Consumers is unable to predict the outcome of these appeals.

2017 Electric Rate Case: In June 2018, the MPSC issued an order authorizing an annual rate increase of $72 million, based on a 10.0 percent authorized return on equity. In July 2018, Consumers filed a reconciliation of total revenues collected from rates it self‑implemented in October 2017 to those that would have been collected under final rates. The reconciliation indicated that a $36 million refund would be required, which was recorded on Consumers’ consolidated balance sheets as a current regulatory liability at March 31, 2019.

2018 Electric Rate Case: In May 2018, Consumers filed an application with the MPSC seeking an annual rate increase of $58 million, based on a 10.75 percent authorized return on equity. The filing requested authority to recover new investment in system reliability, environmental compliance, and technology enhancements. In October 2018, Consumers reduced its requested annual rate increase to $44 million. In January 2019, the MPSC approved a settlement agreement authorizing an annual rate decrease of $24 million, based on a 10.0 percent authorized return of equity. With the elimination of the $113 million TCJA credit to customer bills, the approved settlement agreement results in an $89 million net increase in annual rates. The settlement agreement also provides for deferred accounting treatment for distribution‑related capital investments exceeding certain amounts. Consumers also agreed to not file a new electric rate case prior to January 2020.

Tax Cuts and Jobs Act: The TCJA, which changed existing federal tax law and included numerous provisions that affect businesses, was signed into law in December 2017.

In early 2018, the MPSC ordered Consumers to file various proceedings to determine the reduction in its electric and gas revenue requirements as a result of the reduction in the corporate income tax rate, and to implement bill credits to reflect that reduction until customer rates could be adjusted through Consumers’ general rate cases. Consumers filed, and the MPSC approved, such proceedings throughout 2018, resulting in credits to customer bills during 2018 to reflect reductions in Consumers’ electric and gas revenue requirements.

Consumers filed additional proceedings to address amounts collected from customers during 2018 prior to the implementation of bill credits. In late 2018, the MPSC approved the refund of $31 million to gas customers over six months beginning in December 2018 and the refund of $70 million to electric

52

customers over six months beginning in January 2019. Consumers had a recorded current regulatory liability of $49 million for these approved refunds at March 31, 2019.

In October 2018, Consumers filed an application to address the December 31, 2017 remeasurement of its deferred income taxes and other base rate impacts of the TCJA on customers. In April 2019, Consumers filed rebuttal testimony and is now proposing approval to begin returning $0.4 billion of net regulatory tax liabilities through rates to be determined in Consumers’ pending gas rate case and $1.2 billion through a temporary bill credit until customer rates can be adjusted through an electric rate case. Consumers’ total $1.6 billion of net regulatory tax liabilities comprises:

• A regulatory tax liability of $1.7 billion associated with plant assets that are subject to normalization, which is governed by the Internal Revenue Code. This requires that the regulatory tax liability be returned over the remaining book life of the related plant assets, the average of which is 44 years for gas plant assets and 27 years for electric plant assets.

• A regulatory tax asset of $0.3 billion associated with plant assets that are not subject to normalization. Consumers proposed to collect this over 44 years from gas customers and over 27 years from electric customers.

• A regulatory tax liability of $0.2 billion, which is primarily related to employee benefits. Consumers proposed to refund this amount to customers over ten years.

In January 2018, Consumers began to reduce the regulatory liability subject to normalization by crediting income tax expense. Consumers has fully reserved for the eventual refund of these excess deferred taxes that it has credited to income tax expense in a separate non‑current regulatory liability established by reducing revenue, and will continue to do so until these benefits are passed on to customers in accordance with an MPSC order, expected to be issued in 2019. At March 31, 2019, this reserve for refund of these excess deferred taxes totaled $48 million. For additional details on the remeasurement, see Note 10, Income Taxes.

Energy Waste Reduction Plan Incentive: Consumers will file its 2018 waste reduction reconciliation in May 2019, requesting the MPSC’s approval to collect from customers the maximum performance incentive of $34 million for exceeding its statutory savings targets in 2018. Consumers recognized incentive revenue under this program of $34 million in 2018.

3:    Contingencies and Commitments

CMS Energy and Consumers are involved in various matters that give rise to contingent liabilities. Depending on the specific issues, the resolution of these contingencies could negatively affect CMS Energy’s and Consumers’ liquidity, financial condition, and results of operations. In their disclosures of these matters, CMS Energy and Consumers provide an estimate of the possible loss or range of loss when such an estimate can be made. Disclosures that state that CMS Energy or Consumers cannot predict the outcome of a matter indicate that they are unable to estimate a possible loss or range of loss for the matter.

CMS Energy Contingencies

Gas Index Price Reporting Litigation: CMS Energy, along with CMS MST, CMS Field Services, Cantera Natural Gas, Inc., and Cantera Gas Company, were named as defendants in four class action lawsuits and one individual lawsuit arising as a result of alleged inaccurate natural gas price reporting to publications that report trade information. Allegations include price‑fixing conspiracies, restraint of trade,

53

and artificial inflation of natural gas retail prices in Kansas, Missouri, and Wisconsin. In 2016, CMS Energy entities reached a settlement with the plaintiffs in the Kansas and Missouri class action cases for an amount that was not material to CMS Energy. In 2017, the federal district court approved the settlement. Plaintiffs are making claims for the following: treble damages, full consideration damages, exemplary damages, costs, interest, and/or attorneys’ fees.

After removal to federal court, all of the cases were transferred to a single federal district court pursuant to the multidistrict litigation process. In 2010 and 2011, all claims against CMS Energy defendants were dismissed by the district court based on FERC preemption.

In 2013, the U.S. Court of Appeals for the Ninth Circuit reversed the district court decision. The appellate court found that FERC preemption does not apply under the facts of these cases. The appellate court affirmed the district court’s denial of leave to amend to add federal antitrust claims. The matter was appealed to the U.S. Supreme Court, which in 2015 upheld the Ninth Circuit’s decision. The cases were remanded back to the federal district court.

In 2016, the federal district court granted the defendants’ motion for summary judgment in the individual lawsuit filed in Kansas based on a release in a prior settlement involving similar allegations; the order of summary judgment was subsequently appealed. In March 2018, the U.S. Court of Appeals for the Ninth Circuit reversed the lower court’s ruling and remanded the case back to the federal district court.

In 2017, the federal district court denied plaintiffs’ motion for class certification in the two pending class action cases in Wisconsin. The plaintiffs appealed that decision to the U.S. Court of Appeals for the Ninth Circuit and in August 2018, the Ninth Circuit Court of Appeals reversed and remanded the matter back to the federal district court for further consideration.

In January 2019, the judge in the multidistrict litigation granted motions filed by plaintiffs for Suggestion of Remand of the actions back to the respective transferor courts in Wisconsin and Kansas for further handling. In the Kansas action, the Judicial Panel on Multidistrict Litigation ordered the remand and the case is being transferred. In the Wisconsin actions, oppositions to the remand have been filed and the Judicial Panel on Multidistrict Litigation will likely consider the request in May 2019.

These cases involve complex facts, a large number of similarly situated defendants with different factual positions, and multiple jurisdictions. Presently, any estimate of liability would be highly speculative; the amount of CMS Energy’s reasonably possible loss would be based on widely varying models previously untested in this context. If the outcome after appeals is unfavorable, these cases could negatively affect CMS Energy’s liquidity, financial condition, and results of operations.

Bay Harbor: CMS Land retained environmental remediation obligations for the collection and treatment of leachate, a liquid consisting of water and other substances, at Bay Harbor after selling its interests in the development in 2002. Leachate is produced when water enters into cement kiln dust piles left over from former cement plant operations at the site. In 2012, CMS Land and the MDEQ finalized an agreement that established the final remedies and the future water quality criteria at the site. CMS Land completed all construction necessary to implement the remedies required by the agreement and will continue to maintain and operate a system to discharge treated leachate into Little Traverse Bay under an NPDES permit issued in 2010 and renewed in 2016. The renewed NPDES permit is valid through September 2020.

At March 31, 2019, CMS Energy had a recorded liability of $45 million for its remaining obligations for environmental remediation. CMS Energy calculated this liability based on discounted projected costs, using a discount rate of 4.34 percent and an inflation rate of one percent on annual operating and maintenance costs. The undiscounted amount of the remaining obligation is $57 million. CMS Energy

54

expects to pay the following amounts for long‑term liquid disposal and operating and maintenance costs during the remainder of 2019 and in each of the next five years:

In Millions
	2019			2020			2021			2022			2023			2024
CMS Energy
Long‑term liquid disposal and operating and maintenance costs		$	3		$	4		$	4		$	4		$	4		$	4

CMS Energy’s estimate of response activity costs and the timing of expenditures could change if there are changes in circumstances or assumptions used in calculating the liability. Although a liability for its present estimate of remaining response activity costs has been recorded, CMS Energy cannot predict the ultimate financial impact or outcome of this matter.

Equatorial Guinea Tax Claim: In 2002, CMS Energy sold its oil, gas, and methanol investments in Equatorial Guinea. The government of Equatorial Guinea claims that, in connection with the sale, CMS Energy owes $152 million in taxes, plus substantial penalties and interest that could be up to the amount of the taxes claimed. In 2015, the matter was proceeding to formal arbitration; however, since then, the government of Equatorial Guinea has stopped communicating. CMS Energy has concluded that the government’s tax claim is without merit and will continue to contest the claim, but cannot predict the financial impact or outcome of the matter. An unfavorable outcome could have a material adverse effect on CMS Energy’s liquidity, financial condition, and results of operations.

Consumers Electric Utility Contingencies

Electric Environmental Matters: Consumers’ operations are subject to environmental laws and regulations. Historically, Consumers has generally been able to recover, in customer rates, the costs to operate its facilities in compliance with these laws and regulations.

Cleanup and Solid Waste: Consumers expects to incur remediation and other response activity costs at a number of sites under the NREPA. Consumers believes that these costs should be recoverable in rates, but cannot guarantee that outcome. Consumers estimates that its liability for NREPA sites for which it can estimate a range of loss will be between $3 million and $4 million. At March 31, 2019, Consumers had a recorded liability of $3 million, the minimum amount in the range of its estimated probable NREPA liability, as no amount in the range was considered a better estimate than any other amount.

Consumers is a potentially responsible party at a number of contaminated sites administered under CERCLA. CERCLA liability is joint and several. In 2010, Consumers received official notification from the EPA that identified Consumers as a potentially responsible party for cleanup of PCBs at the Kalamazoo River CERCLA site. The notification claimed that the EPA has reason to believe that Consumers disposed of PCBs and arranged for the disposal and treatment of PCB‑containing materials at portions of the site. In 2011, Consumers received a follow‑up letter from the EPA requesting that Consumers agree to participate in a removal action plan along with several other companies for an area of lower Portage Creek, which is connected to the Kalamazoo River. All parties, including Consumers, that were asked to participate in the removal action plan declined to accept liability. Until further information is received from the EPA, Consumers is unable to estimate a range of potential liability for cleanup of the river.

Based on its experience, Consumers estimates that its share of the total liability for known CERCLA sites will be between $3 million and $8 million. Various factors, including the number and creditworthiness of potentially responsible parties involved with each site, affect Consumers’ share of the total liability. At March 31, 2019, Consumers had a recorded liability of $3 million for its share of the total liability at these

55

sites, the minimum amount in the range of its estimated probable CERCLA liability, as no amount in the range was considered a better estimate than any other amount.

The timing of payments related to Consumers’ remediation and other response activities at its CERCLA and NREPA sites is uncertain. Consumers periodically reviews these cost estimates. A change in the underlying assumptions, such as an increase in the number of sites, different remediation techniques, the nature and extent of contamination, and legal and regulatory requirements, could affect its estimates of NREPA and CERCLA liability.

Ludington PCB: In 1998, during routine maintenance activities, Consumers identified PCB as a component in certain paint, grout, and sealant materials at Ludington. Consumers removed part of the PCB material and replaced it with non‑PCB material. Consumers has had several communications with the EPA regarding this matter, but cannot predict the financial impact or outcome.

MCV PPA: In December 2017, the MCV Partnership initiated arbitration against Consumers, asserting a breach of contract associated with the MCV PPA. Under this PPA, Consumers pays the MCV Partnership a fixed energy charge based on Consumers’ annual average baseload coal generating plant operating and maintenance cost, fuel inventory, and administrative and general expenses. The MCV Partnership asserts that, under the Clean Air Act, Consumers should have installed pollution control equipment on coal‑fueled electric generating units years before they were retired. The MCV Partnership also asserts that Consumers should have installed pollution control equipment earlier on its remaining coal‑fueled electric generating units. Additionally, the MCV Partnership claims that Consumers improperly characterized certain costs included in the calculation of the fixed energy charge.

In January 2019, an arbitration panel issued an order concluding that the MCV Partnership is not entitled to any damages associated with its claim against Consumers related to the Clean Air Act; the majority of the MCV Partnership’s claim, which estimated damages and interest in excess of $270 million, was related to this dismissed claim. Consumers believes that the MCV Partnership’s remaining claims are without merit, but cannot predict the financial impact or outcome of the matter.

Underwater Cables in Straits of Mackinac: Consumers owns certain underwater electric cables in the Straits of Mackinac, which were de‑energized and retired in 1990. Consumers was notified that some of these cables were damaged as a result of vessel activity in April 2018. Following the notification, Consumers located, inspected, sampled, capped, and returned the damaged retired cables to their original location on the lake bottom, and did not find any substantive evidence of environmental contamination. Consumers is collaborating with the State of Michigan, local Native American tribes, and other stakeholders to evaluate the status of the cables and to determine if any additional action is advisable. Consumers cannot predict the outcome of this matter, but if Consumers is required to remove all the cables, it could incur additional costs of up to $10 million. Consumers has filed suit against the companies that own the vessels that allegedly caused the damage. Consumers will seek recovery from customers of any costs incurred.

Consumers Gas Utility Contingencies

Gas Environmental Matters: Consumers expects to incur remediation and other response activity costs at a number of sites under the NREPA. These sites include 23 former MGP facilities. Consumers operated the facilities on these sites for some part of their operating lives. For some of these sites, Consumers has no present ownership interest or may own only a portion of the original site.

At March 31, 2019, Consumers had a recorded liability of $72 million for its remaining obligations for these sites. This amount represents the present value of long‑term projected costs, using a discount rate of 2.57 percent and an inflation rate of 2.5 percent. The undiscounted amount of the remaining obligation is

56

$76 million. Consumers expects to pay the following amounts for remediation and other response activity costs during the remainder of 2019 and in each of the next five years: 

In Millions
	2019			2020			2021			2022			2023			2024
Consumers
Remediation and other response activity costs		$	10		$	16		$	21		$	7		$	2		$	2

Consumers periodically reviews these cost estimates. Any significant change in the underlying assumptions, such as an increase in the number of sites, changes in remediation techniques, or legal and regulatory requirements, could affect Consumers’ estimates of annual response activity costs and the MGP liability.

Pursuant to orders issued by the MPSC, Consumers defers its MGP‑related remediation costs and recovers them from its customers over a ten‑year period. At March 31, 2019, Consumers had a regulatory asset of $131 million related to the MGP sites.

Consumers estimates that its liability to perform remediation and other response activities at NREPA sites other than the MGP sites could reach $3 million. At March 31, 2019, Consumers had a recorded liability of less than $1 million, the minimum amount in the range of its estimated probable liability, as no amount in the range was considered a better estimate than any other amount.

Ray Compressor Station: On January 30, 2019, Consumers experienced a fire at the Ray Compressor Station, which resulted in the Ray Storage Field being off-line or operating at significantly reduced capacity, which negatively affected Consumers’ natural gas supply and delivery capacity. This incident, which occurred during the extreme polar vortex weather condition, required Consumers to request voluntary reductions in customer load, to implement contingency gas supply purchases, and to implement a curtailment of natural gas deliveries for industrial and large commercial customers pursuant to Consumers’ MPSC curtailment tariff. The curtailment and request for voluntary reductions of customer loads were canceled as of midnight, February 1, 2019. Consumers investigated the cause of the incident, and filed a report on the incident with the MPSC in April 2019. As a result of the fire and the resulting curtailment, Consumers could be subject to various claims from impacted customers or claims for damages. Consumers may also be subject to regulatory penalties and disallowances of gas purchased and gas lost. At this time, Consumers cannot predict the outcome of these matters or other gas-related incidents and a reasonable estimate of any loss cannot be made, but they could have a material adverse effect on Consumers’ results of operations, financial condition, or liquidity, and could subject Consumers’ gas utility to increased regulatory scrutiny.

Guarantees

Presented in the following table are CMS Energy’s and Consumers’ guarantees at March 31, 2019:

In Millions
Guarantee Description	Issue Date		Expiration Date		Maximum Obligation			Carrying Amount
CMS Energy, including Consumers
Indemnity obligations from stock and asset sale agreements1		various		indefinite		$	153		$	2
Guarantees2		various		indefinite		36			—
Consumers
Guarantee2		July 2011		indefinite		$	30		$	—

¹  These obligations arose from stock and asset sale agreements under which CMS Energy or a subsidiary of CMS Energy indemnified the purchaser for losses resulting from various matters, primarily claims related to taxes. CMS Energy believes the likelihood of material loss to be remote for the indemnity obligations not recorded as liabilities.

²  At Consumers, this obligation comprises a guarantee provided to the U.S. Department of Energy in connection with a settlement agreement regarding damages resulting from the department’s failure to accept spent nuclear fuel from nuclear power plants formerly owned by Consumers. At CMS Energy, the guarantee obligations comprise Consumers’ guarantee to the U.S. Department of Energy and CMS Energy’s 1994 guarantee of non‑recourse revenue bonds issued by Genesee.

Additionally, in the normal course of business, CMS Energy, Consumers, and certain other subsidiaries of CMS Energy have entered into various agreements containing tax and other indemnity provisions for which they are unable to estimate the maximum potential obligation. The carrying value of these indemnity obligations is $1 million. CMS Energy and Consumers consider the likelihood that they would be required to perform or incur substantial losses related to these indemnities to be remote.

Other Contingencies

In addition to the matters disclosed in this Note and Note 2, Regulatory Matters, there are certain other lawsuits and administrative proceedings before various courts and governmental agencies, as well as unasserted claims, which may result in such proceedings, arising in the ordinary course of business to which CMS Energy, Consumers, and certain other subsidiaries of CMS Energy are parties. These other lawsuits, proceedings, and unasserted claims may involve personal injury, property damage, contracts, environmental matters, federal and state taxes, rates, licensing, employment, and other matters. Further, CMS Energy and Consumers occasionally self‑report certain regulatory non‑compliance matters that may or may not eventually result in administrative proceedings. CMS Energy and Consumers believe that the outcome of any one of these proceedings and potential claims will not have a material negative effect on their consolidated results of operations, financial condition, or liquidity.

¹  These unsecured obligations rank subordinate and junior in right of payment to all of CMS Energy’s existing and future senior indebtedness.

Revolving Credit Facilities: The following revolving credit facilities with banks were available at March 31, 2019:

In Millions
Expiration Date	Amount of Facility			Amount Borrowed			Letters of Credit Outstanding			Amount Available
CMS Energy, parent only
June 5, 2023		$	550		$	—		$	4		$	546

¹  Under this facility, $8 million is available solely for the purpose of issuing letters of credit. Obligations under this facility are secured by the collateral accounts with the lending bank.

²  Obligations under these facilities are secured by first mortgage bonds of Consumers.

Short‑term Borrowings: Under Consumers’ commercial paper program, Consumers may issue, in one or more placements, commercial paper notes with maturities of up to 365 days and that bear interest at fixed or floating rates. These issuances are supported by Consumers’ revolving credit facilities and may have an aggregate principal amount outstanding of up to $500 million. While the amount of outstanding commercial paper does not reduce the available capacity of the revolving credit facilities, Consumers

59

does not intend to issue commercial paper in an amount exceeding the available capacity of the facilities. At March 31, 2019, $30 million of commercial paper notes were outstanding under this program.

Dividend Restrictions: At March 31, 2019, payment of dividends by CMS Energy on its common stock was limited to $4.9 billion under provisions of the Michigan Business Corporation Act of 1972.

Under the provisions of its articles of incorporation, at March 31, 2019, Consumers had $1.3 billion of unrestricted retained earnings available to pay dividends on its common stock to CMS Energy. Provisions of the Federal Power Act and the Natural Gas Act appear to restrict dividends payable by Consumers to the amount of Consumers’ retained earnings. Several decisions from FERC suggest that, under a variety of circumstances, dividends from Consumers on its common stock would not be limited to amounts in Consumers’ retained earnings. Any decision by Consumers to pay dividends on its common stock in excess of retained earnings would be based on specific facts and circumstances and would be subject to a formal regulatory filing process.

For the three months ended March 31, 2019, Consumers paid $172 million in dividends on its common stock to CMS Energy.

Issuance of Common Stock: In 2018, CMS Energy entered into an equity offering program under which it may sell, from time to time, shares of CMS Energy common stock having an aggregate sales price of up to $250 million. Under this program, CMS Energy may sell its common stock in privately negotiated transactions, in “at the market” offerings, through forward sales transactions or otherwise. As of March 31, 2019, CMS Energy had entered into forward sales contracts having an aggregate sales price of $250 million. Presented in the following table are details of these contracts:

Contract Date	Maturity Date	Number of Shares	Initial Forward Price Per Share
November 16, 2018	May 16, 2020	2,017,783		$	49.06
November 20, 2018	May 20, 2020	777,899		50.91
February 21, 2019	August 21, 2020	2,083,340		52.27

These contracts allow CMS Energy to either physically settle the contracts by issuing shares of its common stock at the then‑applicable forward sale price specified by the agreement or net settle the contracts through the delivery or receipt of cash or shares. CMS Energy may settle the contracts at any time through their maturity dates, and presently intends to physically settle the contracts by delivering shares of its common stock.

The initial forward price in the forward equity sale contracts includes a deduction for commissions and will be adjusted on a daily basis over the term based on an interest rate factor and decreased on certain dates by certain predetermined amounts to reflect expected dividend payments.

No amounts have or will be recorded on CMS Energy’s consolidated balance sheets until settlements of the forward equity sale contracts occur. If CMS Energy had elected to net share settle the contracts as of March 31, 2019, CMS Energy would have been required to deliver 424,770 shares.

5:    Fair Value Measurements

Accounting standards define fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. When measuring fair value, CMS Energy and Consumers are required to incorporate all assumptions that market participants would use in pricing an asset or liability, including assumptions about risk. A fair value hierarchy prioritizes inputs used to measure fair value according to their observability in the market. The three levels of the fair value hierarchy are as follows:

• Level 1 inputs are unadjusted quoted prices in active markets for identical assets or liabilities.

• Level 2 inputs are observable, market‑based inputs, other than Level 1 prices. Level 2 inputs may include quoted prices for similar assets or liabilities in active markets, quoted prices in inactive markets, and inputs derived from or corroborated by observable market data.

• Level 3 inputs are unobservable inputs that reflect CMS Energy’s or Consumers’ own assumptions about how market participants would value their assets and liabilities.

CMS Energy and Consumers classify fair value measurements within the fair value hierarchy based on the lowest level of input that is significant to the fair value measurement in its entirety.

Assets and Liabilities Measured at Fair Value on a Recurring Basis

Presented in the following table are CMS Energy’s and Consumers’ assets and liabilities recorded at fair value on a recurring basis:

¹  All assets and liabilities were classified as Level 1 with the exception of derivative contracts, which were classified as Level 2 or Level 3.

61

Cash Equivalents: Cash equivalents and restricted cash equivalents consist of money market funds with daily liquidity. Short‑term debt instruments classified as cash equivalents on the consolidated balance sheets are not included since they are recorded at amortized cost.

Nonqualified Deferred Compensation Plan Assets and Liabilities: The nonqualified deferred compensation plan assets consist of mutual funds, which are valued using the daily quoted net asset values. CMS Energy and Consumers value their nonqualified deferred compensation plan liabilities based on the fair values of the plan assets, as they reflect the amount owed to the plan participants in accordance with their investment elections. CMS Energy and Consumers report the assets in other non‑current assets and the liabilities in other non‑current liabilities on their consolidated balance sheets.

DB SERP Cash Equivalents: The DB SERP cash equivalents consist of a money market fund with daily liquidity and are reported in other non‑current assets on CMS Energy and Consumers’ consolidated balance sheets.

Derivative Instruments: CMS Energy and Consumers value their derivative instruments using either a market approach that incorporates information from market transactions, or an income approach that discounts future expected cash flows to a present value amount. CMS Energy’s and Consumers’ derivatives are classified as Level 2 or Level 3.

The derivatives classified as Level 2 are interest rate swaps at CMS Energy, which are valued using market‑based inputs. CMS Energy uses interest rate swaps to manage its interest rate risk on certain long‑term debt transactions and certain notes receivable at EnerBank. The majority of derivatives classified as Level 3 are FTRs held by Consumers. Consumers uses FTRs to manage price risk related to electricity transmission congestion. An FTR is a financial instrument that entitles its holder to receive compensation or requires its holder to remit payment for congestion‑related transmission charges. Due to the lack of quoted pricing information, Consumers determines the fair value of its FTRs based on Consumers’ average historical settlements. There was no material activity within the Level 3 categories of assets and liabilities during the periods presented.

The effects of third‑party credit enhancements were excluded from the fair value measurements of long‑term debt. The principal amount of CMS Energy’s long‑term debt supported by third‑party credit enhancements was $35 million at March 31, 2019 and December 31, 2018. The entirety of these amounts was at Consumers.

EnerBank Notes Receivable

EnerBank notes receivable are primarily unsecured consumer installment loans for financing home improvements. EnerBank records its notes receivable at cost, less an allowance for loan losses.

During the three months ended March 31, 2019, EnerBank purchased a portfolio of secured and unsecured consumer installment loans with a principal value of $131 million at March 31, 2019.

64

Authorized contractors pay fees to EnerBank to provide borrowers with same‑as‑cash, zero interest, or reduced interest loans. Unearned income associated with the loan fees, which is recorded as a reduction to notes receivable on CMS Energy’s consolidated balance sheets, was $111 million at March 31, 2019 and $102 million at December 31, 2018.

The allowance for loan losses is a valuation allowance to reflect estimated credit losses. The allowance is increased by the provision for loan losses and decreased by loan charge‑offs net of recoveries. Management estimates the allowance balance required by taking into consideration historical loan loss experience, the nature and volume of the portfolio, economic conditions, and other factors. Loan losses are charged against the allowance when the loss is confirmed, but no later than the point at which a loan becomes 120 days past due.

Loans that are 30 days or more past due are considered delinquent. The balance of EnerBank’s delinquent consumer loans was $20 million at March 31, 2019 and $21 million at December 31, 2018.

At March 31, 2019 and December 31, 2018, $1 million of EnerBank’s loans had been modified as troubled debt restructurings.

EnerBank has entered into an interest rate swap on $36 million of its loans (notes receivable). The terms of the swap effectively convert the fixed rate interest received on these loans to a variable rate. EnerBank is applying fair value hedge accounting to the swap, and accordingly is adjusting the the carrying value of the loans for the change in the fair value of the loans due to the hedged interest rate risk. The adjustment to the loans at March 31, 2019 was immaterial.

DB SERP Note Receivable – Related Party

The DB SERP note receivable – related party is Consumers’ portion of a demand note payable issued by CMS Energy to the DB SERP rabbi trust. The demand note bears interest at an annual rate of 4.10 percent and has a maturity date of 2028.

8:Leases

Lessee

CMS Energy and Consumers lease various assets from third parties, including railcars, real estate, service vehicles, and gas pipeline capacity. In addition, CMS Energy and Consumers account for a number of their PPAs as finance and operating leases.

CMS Energy and Consumers do not record right-of-use assets or lease liabilities on their balance sheets for rentals with lease terms of 12 months or less, most of which are for the lease of real estate and fleet vehicles. Lease expense for these rentals is recognized on a straight-line basis over the lease term. Consumers includes future payments for all renewal options that it is reasonably certain to exercise in its measurement of lease right-of-use assets and lease liabilities. CMS Energy and Consumers include executory costs in the measurement of their right-of-use assets and lease liabilities, except for maintenance costs related to their railcar leases.

Operating leases for coal-carrying railcars have original lease terms ranging from five to 15 years, expiring over the next four years with options to renew. These leases contain fair market value extension and buyout provisions.

65

Operating leases for real estate have original lease terms ranging from three to 60 years, expiring over the next 42 years. These leases contain fair market value extension and buyout provisions.

Finance leases for Consumers’ service vehicles have original lease terms ranging from five to ten years, expiring over the next eight years. Some have end-of-lease rental adjustment clauses based on proceeds received from the sale or disposition of the vehicles, and others have fair market value purchase options.

Consumers has finance leases for gas transportation pipelines to the D.E. Karn generating complex and Zeeland. The finance lease for the gas transportation pipeline into the D.E. Karn generating complex has a term of 15 years with a provision to extend the contract from month to month. The remaining term of the contract was three years at March 31, 2019. The finance lease for the gas transportation pipeline to Zeeland was extended in 2017 for five years pursuant to a renewal provision in the contract, with additional renewal provisions of five to ten years.

The remaining terms of Consumers’ long-term PPAs accounted for as finance and operating leases range between one and 14 years. Most of these PPAs contain provisions at the end of the initial contract terms to renew the agreements annually under mutually agreed‑upon terms at the time of renewal. Energy and capacity payments that vary depending on quantities delivered are recognized as variable lease costs when incurred. Consumers accounts for a PPA with one of CMS Energy’s equity method subsidiaries as a lease.

Presented in the following table is information about CMS Energy’s and Consumers’ lease right-of-use assets and lease liabilities:

¹  CMS Energy’s and Consumers’ operating right-of-use lease assets are reported as other non-current assets on their consolidated balance sheets.

²  The current portion of CMS Energy’s and Consumers’ operating lease liabilities are reported as other current liabilities on their consolidated balance sheets.

66

³  The non-current portion of CMS Energy’s and Consumers’ operating lease liabilities are reported as other non-current liabilities on their consolidated balance sheets.

⁴  This includes $25 million for leases with related parties, of which less than $1 million is current.

⁵  This rate excludes the impact of Consumers’ pipeline agreements and long-term PPAs accounted for as finance leases. The required capacity payments under these agreements, when compared to the underlying fair value of the leased assets, result in effective interest rates that exceed market rates for leases with similar terms.

CMS Energy and Consumers report operating, variable, and short-term lease costs as operating expenses on their consolidated statements of income, except for certain amounts that may be capitalized to other assets. Presented in the following table is a summary of CMS Energy’s and Consumers’ total lease costs:

CMS Energy has power sales agreements that are accounted for as operating leases. These agreements have remaining terms ranging from seven to 24 years. In addition to fixed payments, these agreements have variable payments based on energy delivered. CMS Energy’s lease revenue from its power sales agreements was $48 million for the three months ended March 31, 2019, which included variable lease payments of $34 million.

Consumers has an agreement to build, own, operate, and maintain a compressed natural gas fueling station for a term of 20 years, which began in December 2018. This agreement is accounted for as a direct finance lease, under which the lessee has the option to purchase the natural gas fueling station at the end of the lease term. Fixed monthly payments escalate annually with inflation.

69

In December 2018, Consumers and a subsidiary of CMS Energy executed a 20-year natural gas transportation agreement, related to a pipeline owned by Consumers, which will automatically extend annually unless terminated by either party. This agreement is accounted for by Consumers as a direct finance lease. The effects of the lease are eliminated on CMS Energy’s consolidated financial statements.

10:    Income Taxes

Presented in the following table is a reconciliation of the statutory U.S. federal income tax rate to the effective income tax rate from continuing operations:

Research and development tax credits, net3	(0.2	)	(2.7	)
Other, net	(0.3	)	(0.3	)
Effective tax rate	19.3	%	15.4	%

¹  In December 2017, Consumers remeasured its deferred tax assets and liabilities at the new federal tax rate enacted by the TCJA and recorded a $1.8 billion regulatory liability. This regulatory liability relates to the excess deferred taxes arising from accelerated tax depreciation on assets in rate base that are governed by normalization provisions of the Internal Revenue Code. The normalization provisions require that the excess deferred taxes be refunded to customers over the remaining average service life of the associated assets. In January 2018, Consumers began to reduce this regulatory liability by crediting income tax expense. Consumers has fully reserved for the eventual refund of these excess deferred taxes that it has credited to income tax expense in a separate non‑current regulatory liability established by reducing revenue, and will continue to do so until these benefits are passed on to customers in accordance with an MPSC order, expected to be issued in 2019. At March 31, 2019, this reserve for refund of these excess deferred taxes totaled $48 million.

²  In 2013, the MPSC issued an order authorizing Consumers to accelerate the flow‑through to electric and gas customers of certain income tax benefits associated primarily with the cost of removal of plant placed in service before 1993. Consumers implemented this regulatory treatment beginning in 2014, with the electric portion ending in 2018. This change, which also accelerates Consumers’ recognition of the income tax benefits, reduced Consumers’ income tax expense by $7 million for the three months ended March 31, 2019 and by $14 million for the three months ended March 31, 2018.

³  In March 2018, Consumers finalized a study of research and development tax credits for the tax years 2012 through 2016. As a result, Consumers recognized an $8 million increase in the credit, net of reserves for uncertain tax positions, at that time.

11:    Earnings Per Share—CMS Energy

Net income per average common share available to common stockholders
Basic		$	0.75		$	0.86
Diluted		0.75			0.86

Nonvested Stock Awards

CMS Energy’s nonvested stock awards are composed of participating and non‑participating securities. The participating securities accrue cash dividends when common stockholders receive dividends. Since the recipient is not required to return the dividends to CMS Energy if the recipient forfeits the award, the nonvested stock awards are considered participating securities. As such, the participating nonvested stock awards were included in the computation of basic EPS. The non‑participating securities accrue stock dividends that vest concurrently with the stock award. If the recipient forfeits the award, the stock dividends accrued on the non‑participating securities are also forfeited. Accordingly, the non‑participating awards and stock dividends were included in the computation of diluted EPS, but not in the computation of basic EPS.

Forward Equity Sale Contracts

In November 2018 and February 2019, CMS Energy entered into forward equity sale contracts. These forward equity sale contracts are non‑participating securities. While the forward sale price in the forward equity sale contract is decreased on certain dates by certain predetermined amounts to reflect expected dividend payments, these price adjustments were set upon inception of the agreement and the forward contract does not give the owner the right to participate in undistributed earnings. Accordingly, the forward equity sale contracts were included in the computation of diluted EPS, but not in the computation of basic EPS. For further details on the forward equity sale contracts, see Note 4, Financings and Capitalization.

Electric and Gas Utilities

Consumers Utility Revenue: Consumers recognizes revenue primarily from the sale of electric and gas utility services at tariff‑based rates regulated by the MPSC. Consumers’ customer base consists of a mix of residential, commercial, and diversified industrial customers. Consumers’ tariff‑based sales performance obligations are described below.

• Consumers has performance obligations for the service of standing ready to deliver electricity or natural gas to customers, and it satisfies these performance obligations over time. Consumers recognizes revenue at a fixed rate as it provides these services. These arrangements generally do not have fixed terms and remain in effect as long as the customer consumes the utility service. The rates are set by the MPSC through the rate‑making process and represent the stand‑alone selling price of Consumers’ service to stand ready to deliver.

• Consumers has performance obligations for the service of delivering the commodity of electricity or natural gas to customers, and it satisfies these performance obligations upon delivery. Consumers recognizes revenue at a price per unit of electricity or natural gas delivered, based on the tariffs established by the MPSC. These arrangements generally do not have fixed terms and remain in effect as long as the customer consumes the utility service. The rates are set by the

75

MPSC through the rate‑making process and represent the stand‑alone selling price of a bundled product comprising the commodity, electricity or natural gas, and the service of delivering such commodity.

In some instances, Consumers has specific fixed‑term contracts with large commercial and industrial customers to provide electricity or gas at certain tariff rates or to provide gas transportation services at contracted rates. The amount of electricity and gas to be delivered under these contracts and the associated future revenue to be received are generally dependent on the customers’ needs. Accordingly, Consumers recognizes revenues at the tariff or contracted rate as electricity or gas is delivered to the customer. Consumers also has other miscellaneous contracts with customers related to pole and other property rentals, appliance service plans, and utility contract work. Generally, these contracts are short term or evergreen in nature.

Accounts Receivable and Unbilled Revenues: Accounts receivable comprise trade receivables and unbilled receivables. CMS Energy and Consumers record their accounts receivable at cost, which approximates fair value. CMS Energy and Consumers establish an allowance for uncollectible accounts based on historical losses, management’s assessment of existing economic conditions, customer payment trends, and other factors. CMS Energy and Consumers assess late payment fees on trade receivables based on contractual past‑due terms established with customers. CMS Energy and Consumers charge off accounts deemed uncollectible to operating expense. Uncollectible expense for CMS Energy, including Consumers, was $6 million for the three months ended March 31, 2019 and $7 million for the three months ended March 31, 2018. Uncollectible expense for Consumers was $6 million for the three months ended March 31, 2019 and $7 million for the three months ended March 31, 2018.

Consumers’ customers are billed monthly in cycles having billing dates that do not generally coincide with the end of a calendar month. This results in customers having received electricity or natural gas that they have not been billed for as of the month‑end. Consumers estimates its unbilled revenues by applying an average billed rate to total unbilled deliveries for each customer class. Unbilled revenues, which are recorded as accounts receivable on CMS Energy’s and Consumers’ consolidated balance sheets, were $341 million at March 31, 2019 and $409 million at December 31, 2018.

Alternative‑Revenue Programs: Under a gas revenue decoupling mechanism authorized by the MPSC, Consumers is allowed to adjust future gas rates for differences between Consumers’ actual weather‑normalized non‑fuel revenues and the revenues approved by the MPSC. Consumers accounts for this program as an alternative‑revenue program that meets the criteria for recognizing the effects of decoupling adjustments on revenue as gas is delivered.

Consumers does not reclassify revenue from its alternative-revenue program to revenue from contracts with customers at the time the amounts are collected from customers.
