Question: How does Consumers finance its clean energy investments?

Consumers Energy finances its clean energy investments through a combination of regulatory-approved mechanisms and strategic acquisitions. The company leverages securitization bonds to recover costs associated with retiring coal-fueled generating units. For instance, it issued bonds in December 2023 to finance the recovery of the D.E. Karn coal units. Additionally, the MPSC has authorized the use of regulatory asset treatment for recovering the remaining book value of the J.H. Campbell units, providing a 9.0% return on equity starting in 2025.

To further expand its clean energy portfolio, Consumers has purchased the Covert Generating Station and conducted a competitive solicitation process to secure up to 700 MW of capacity through Power Purchase Agreements (PPAs), including dispatchable sources. These steps, combined with plans to increase renewable energy capacity and deploy battery storage, highlight a well-structured approach to financing its transition towards net-zero carbon emissions.

Consumers Electric Utility Outlook and Uncertainties

Clean Energy Plan: Consumers' Clean Energy Plan details its strategy to meet customers' long-term energy needs and provides the foundation for its goal to achieve net-zero carbon emissions from its electric business by 2040. Under this net-zero goal, Consumers plans to eliminate the impact of carbon emissions created by the electricity it generates or purchases for customers. Additionally, through its Clean Energy Plan, Consumers continues to make progress on expanding its customer programs, namely its demand response, energy efficiency, and conservation voltage reduction programs, as well as increasing its renewable energy generation.
The Clean Energy Plan was most recently revised and approved by the MPSC in 2022. Under this plan, Consumers will eliminate the use of coal-fueled generation in 2025 and expects to meet 90 percent of its customers' needs with clean energy sources by 2040. Specifically, the Clean Energy Plan provides for:
•the retirement of the D.E. Karn coal-fueled generating units, totaling 515 MW of nameplate capacity; these units closed in June 2023
•the retirement of the J.H. Campbell coal-fueled generating units, totaling 1,407 MW of nameplate capacity, in 2025
•the retirement of the D.E. Karn oil and gas-fueled generating units, totaling 1,219 MW of nameplate capacity, in 2031
The MPSC authorized Consumers to issue securitization bonds to finance the recovery of and return on the D.E. Karn coal-fueled generating units; Consumers issued these bonds in December 2023. Additionally, the MPSC has authorized regulatory asset treatment for Consumers to recover the remaining book value of the J.H. Campbell coal-fueled generating units, as well as a 9.0‑percent return on equity, commencing in 2025.

Under the Clean Energy Plan, Consumers:

•purchased the Covert Generating Station, a natural gas-fueled generating facility with 1,200 MW of nameplate capacity in Van Buren County, Michigan in May 2023

•conducted a one‑time competitive solicitation for up to 700 MW of capacity through PPAs from sources able to deliver to Michigan's Lower Peninsula beginning in 2025 (including up to 500 MW from dispatchable sources)
These actions are expected to help Consumers continue to provide controllable sources of electricity to customers while expanding its investment in renewable energy. The Clean Energy Plan forecasts renewable energy capacity levels of 30 percent in 2025, 43 percent in 2030, and 61 percent in 2040, including the addition of nearly 8,000 MW of solar generation. Additionally, Consumers plans to deploy battery storage beginning in 2024, with 75 MW of energy storage expected by 2027 and an additional 475 MW by 2040. The 2023 Energy Law, enacted in November 2023, set more ambitious standards for renewable energy and energy storage. Consumers is required to file updates to its amended renewable energy plan before or in November 2024 and its Clean Energy Plan before or in 2027. Together, these updated plans will outline a path to meeting these accelerated timelines.
Under its Clean Energy Plan, Consumers bids new capacity competitively and expects to own and operate approximately 50 percent of new capacity, with the remainder being built and owned by third parties. Additionally, Consumers earns a return equal to its pre-tax weighted-average cost of capital on permanent capital structure on payments made under new competitively bid PPAs with non‑affiliated entities approved by the MPSC.
As a result of requests for proposals, Consumers has entered into PPAs to purchase renewable capacity, energy, and RECs from solar generating facilities and build transfer agreements to purchase solar generating facilities.

Question: How is the company managing litigation risks related to environmental issues?

Consumers Energy manages significant litigation risks related to environmental and contractual issues. In compliance with environmental laws, the company addresses liabilities under CERCLA and NREPA, including the cleanup of contaminated sites like the Kalamazoo River. Consumers estimates its liabilities for these sites to range between $3 million and $8 million for CERCLA and $4 million for NREPA, with amounts subject to periodic review. Additionally, Consumers and DTE Electric are engaged in litigation against TAES and Toshiba over defective work on the Ludington Pumped Storage Plant, with potential damages of $15 million, of which Consumers could be liable for 51%. Another key litigation involves Wolverine Power, which has claimed $37 million in damages over the early retirement of the J.H. Campbell 3 unit. While the court upheld Consumers’ right to retire the unit, some breach of agreement claims are still pending resolution. These legal matters, if resolved unfavorably, could materially impact Consumers’ financial condition.

The order directed Consumers to provide information on such meters and their replacement, meter-reading performance, communications with customers and the MPSC regarding these issues, and other information. Subsequently, the MPSC issued a show-cause order directing Consumers to provide further information on consecutive estimated billings, the provision of actual meter readings, and new service installation issues.
In April 2024, Consumers signed an agreement with the MPSC Staff and Attorney General settling this matter. Under the settlement agreement, Consumers will pay a $1 million penalty to the MPSC and will return to customers a minimum of $3 million, which may be satisfied with amounts received through an associated claim Consumers has filed against a vendor. The settlement agreement is subject to MPSC approval.

2:    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 stating 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

Bay Harbor: CMS Land retained environmental remediation obligations for the collection and treatment of leachate 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 EGLE finalized an agreement establishing 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, which is valid through 2025.
At March 31, 2024, CMS Energy had a recorded liability of $44 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 $56 million. CMS Energy expects to pay the following amounts for long-term leachate disposal and operating and maintenance costs during the remainder of 2024 and in each of the next five years:
|    |                                                                 |      |      |      |      |      |      |    |    |    |    |    |    |    |    |    |

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.

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 NREPA. Consumers believes that these costs should be recoverable in rates, but cannot guarantee that outcome. Consumers estimates its liability for NREPA sites for which it can estimate a range of loss to be between $4 million and $5 million. At March 31, 2024, Consumers had a recorded liability of $4 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 had 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 asked to participate in the removal action plan, including Consumers, 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 its share of the total liability for known CERCLA sites to 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, 2024, Consumers had a recorded liability of $3 million for its share of the total liability at these 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 Overhaul Contract Dispute: Consumers and DTE Electric, co-owners of Ludington, are parties to a 2010 engineering, procurement, and construction agreement with TAES, under which TAES contracted to perform a major overhaul and upgrade of Ludington. The overhauled Ludington units are operational, but TAES' work has been defective and non‑conforming. Consumers and DTE Electric have demanded that TAES provide a comprehensive plan to resolve those matters, including adherence to its warranty commitments and other contractual obligations. Consumers and DTE Electric have taken extensive efforts to resolve these issues with TAES, including a formal demand to TAES' parent, Toshiba, under a parent guaranty it provided.

Consumers believes the counterclaims filed by TAES and Toshiba are without merit, but cannot predict the financial impact or outcome of this matter. An unfavorable outcome could have a material adverse effect on CMS Energy's and Consumers' financial condition, results of operations, or liquidity.
Toshiba has announced that, through a common stock purchase, TBJH became the majority shareholder and new parent company of Toshiba. TBJH is a subsidiary of a Japanese private equity firm. Consumers and DTE Electric continue to monitor this development, but do not believe that this affects their rights under the parent guaranty provided by Toshiba.
In May 2023, the MPSC approved Consumers' and DTE Electric's jointly-filed request for authority to defer as a regulatory asset the costs associated with repairing or replacing the defective work performed by TAES while the litigation with TAES and Toshiba moves forward; such costs will be offset by potential future litigation proceeds received from TAES or Toshiba. Consumers and DTE Electric will have the opportunity to seek appropriate recovery and ratemaking treatment for amounts recorded as a regulatory asset following resolution of the litigation, but cannot predict the financial impact or outcome of such proceedings.
J.H. Campbell 3 Contract Dispute: In 2022, Consumers filed a complaint against Wolverine Power in the Ottawa County Circuit Court and requested a ruling that Consumers has sole authority to decide to retire the J.H. Campbell 3 coal-fueled generating unit under Consumers' and Wolverine Power's agreement to jointly own and operate the unit. Wolverine Power filed an answer, affirmative defenses, and a counterclaim seeking approximately $37 million in damages allegedly caused by Consumers' decision to retire the unit before the end of its useful life. The state circuit court judge found that Consumers may, in its sole discretion, retire J.H. Campbell 3, provided that Consumers continues to operate and make necessary improvements to the unit while the litigation concerning Wolverine Power's claim for damages is pending. In May 2023, the circuit court judge issued an order granting Consumers' motion for clarification confirming that Consumers may continue to operate and invest in J.H. Campbell 3 consistent with the May 2025 retirement date.
In March 2024, the circuit court judge issued an order denying Wolverine Power's motion for partial summary disposition and granting in part and denying in part Consumers' motion for summary disposition. The judge granted Consumers' motion for summary disposition on Wolverine Power's claim that Consumers acted in bad faith in deciding to retire J.H. Campbell 3 early, finding no evidence to support that claim. The judge held that Wolverine Power did identify a genuine issue of material fact as to whether Consumers breached the joint ownership and operating agreement by failing to notify and consult with Wolverine Power regarding the unit's early retirement.
Consumers believes Wolverine Power's claim has no merit, but cannot predict the final impact or outcome on this matter. An unfavorable outcome could have a material adverse effect on CMS Energy's and Consumers' financial condition, results of operations, or liquidity.

CMS Energy Contingencies

Bay Harbor: CMS Land retained environmental remediation obligations for the collection and treatment of leachate 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 EGLE finalized an agreement establishing 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, which is valid through 2025.
At March 31, 2024, CMS Energy had a recorded liability of $44 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 $56 million. CMS Energy expects to pay the following amounts for long-term leachate disposal and operating and maintenance costs during the remainder of 2024 and in each of the next five years:
|    |                                                                 |      |      |      |      |      |      |    |    |    |    |    |    |    |    |    |

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.

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 NREPA. Consumers believes that these costs should be recoverable in rates, but cannot guarantee that outcome. Consumers estimates its liability for NREPA sites for which it can estimate a range of loss to be between $4 million and $5 million. At March 31, 2024, Consumers had a recorded liability of $4 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 had 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 asked to participate in the removal action plan, including Consumers, 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 its share of the total liability for known CERCLA sites to 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, 2024, Consumers had a recorded liability of $3 million for its share of the total liability at these 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 Overhaul Contract Dispute: Consumers and DTE Electric, co-owners of Ludington, are parties to a 2010 engineering, procurement, and construction agreement with TAES, under which TAES contracted to perform a major overhaul and upgrade of Ludington. The overhauled Ludington units are operational, but TAES' work has been defective and non‑conforming. Consumers and DTE Electric have demanded that TAES provide a comprehensive plan to resolve those matters, including adherence to its warranty commitments and other contractual obligations. Consumers and DTE Electric have taken extensive efforts to resolve these issues with TAES, including a formal demand to TAES' parent, Toshiba, under a parent guaranty it provided. TAES has not provided a comprehensive plan or otherwise met its performance obligations.
In order to enforce the contract, Consumers and DTE Electric filed a complaint against TAES and Toshiba in the U.S. District Court for the Eastern District of Michigan in 2022. TAES and Toshiba filed a motion to dismiss the complaint, along with an answer and counterclaims seeking approximately $15 million in damages related to payments allegedly owed under the parties' contract.

The state circuit court judge found that Consumers may, in its sole discretion, retire J.H. Campbell 3, provided that Consumers continues to operate and make necessary improvements to the unit while the litigation concerning Wolverine Power's claim for damages is pending. In May 2023, the circuit court judge issued an order granting Consumers' motion for clarification confirming that Consumers may continue to operate and invest in J.H. Campbell 3 consistent with the May 2025 retirement date.
In March 2024, the circuit court judge issued an order denying Wolverine Power's motion for partial summary disposition and granting in part and denying in part Consumers' motion for summary disposition. The judge granted Consumers' motion for summary disposition on Wolverine Power's claim that Consumers acted in bad faith in deciding to retire J.H. Campbell 3 early, finding no evidence to support that claim. The judge held that Wolverine Power did identify a genuine issue of material fact as to whether Consumers breached the joint ownership and operating agreement by failing to notify and consult with Wolverine Power regarding the unit's early retirement.
Consumers believes Wolverine Power's claim has no merit, but cannot predict the final impact or outcome on this matter. An unfavorable outcome could have a material adverse effect on CMS Energy's and Consumers' financial condition, results of operations, or liquidity.

Question: What steps are being taken to comply with renewable energy standards?

Consumers Energy is actively advancing its renewable energy initiatives to comply with the 2023 Energy Law, which raises the renewable energy standard to 50% by 2030 and 60% by 2035. The company meets these targets through the use of Renewable Energy Credits (RECs), combining newly generated RECs with those carried over from previous years. The Michigan Public Service Commission (MPSC) has approved the development of up to 525 MW of new wind generation projects, including a 150-MW project in Gratiot County (operational in 2020), a 166-MW project in Hillsdale (operational in 2021), and a 201-MW project in Gratiot County (operational in December 2023). Consumers has also secured a 20-year Power Purchase Agreement (PPA) for 100 MW of renewable capacity from a 149-MW solar facility in Calhoun County, expected to be operational in 2024. Additionally, through its Voluntary Large Customer Renewable Energy Program, Consumers is expanding renewable energy offerings for large customers. This program includes a 309-MW solar project in Calhoun County (operational in 2025) and an 85-MW solar project at the D.E. Karn site (operational in 2026). These initiatives underscore Consumers’ commitment to expanding renewable energy capacity and meeting future regulatory standards.

CMS ENERGY CORP 10-Q form for quarterly period ended 2024-03-31, page 31:
Under the Clean Energy Plan, Consumers:

•purchased the Covert Generating Station, a natural gas-fueled generating facility with 1,200 MW of nameplate capacity in Van Buren County, Michigan in May 2023

•conducted a one‑time competitive solicitation for up to 700 MW of capacity through PPAs from sources able to deliver to Michigan's Lower Peninsula beginning in 2025 (including up to 500 MW from dispatchable sources)
These actions are expected to help Consumers continue to provide controllable sources of electricity to customers while expanding its investment in renewable energy. The Clean Energy Plan forecasts renewable energy capacity levels of 30 percent in 2025, 43 percent in 2030, and 61 percent in 2040, including the addition of nearly 8,000 MW of solar generation. Additionally, Consumers plans to deploy battery storage beginning in 2024, with 75 MW of energy storage expected by 2027 and an additional 475 MW by 2040. The 2023 Energy Law, enacted in November 2023, set more ambitious standards for renewable energy and energy storage. Consumers is required to file updates to its amended renewable energy plan before or in November 2024 and its Clean Energy Plan before or in 2027. Together, these updated plans will outline a path to meeting these accelerated timelines.
Under its Clean Energy Plan, Consumers bids new capacity competitively and expects to own and operate approximately 50 percent of new capacity, with the remainder being built and owned by third parties. Additionally, Consumers earns a return equal to its pre-tax weighted-average cost of capital on permanent capital structure on payments made under new competitively bid PPAs with non‑affiliated entities approved by the MPSC.
As a result of requests for proposals, Consumers has entered into PPAs to purchase renewable capacity, energy, and RECs from solar generating facilities and build transfer agreements to purchase solar generating facilities. Presented in the following illustration is the aggregate renewable capacity that Consumers expects to add to its portfolio as a result of these agreements:

Question: How is Consumers addressing risks from severe weather events?

Consumers Energy acknowledges that the increased frequency and intensity of severe weather events, often driven by climate change, could significantly impact its facilities, energy sales, and operational results. While the company cannot predict specific events, it evaluates the potential physical impacts, including heightened storm activity, increased precipitation, rising temperatures, and changes in lake and river levels. In 2022, Consumers released a detailed report addressing these physical risks and their potential effects on its infrastructure. To mitigate these risks, the company is implementing various measures, including infrastructure upgrades and operational enhancements, ensuring greater resilience and preparedness against extreme weather conditions.

CMS ENERGY CORP 10-Q form for quarterly period ended 2024-03-31, page 35: strategy. Consumers will continue to monitor NAAQS rulemakings and evaluate potential impacts to its generating assets.
Consumers continues to evaluate these rules in conjunction with other EPA and EGLE rulemakings, litigation, executive orders, treaties, and congressional actions. 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 operated, including the installation of additional emission control equipment
•the retirement, mothballing, or repowering with an alternative fuel of some of Consumers' generating units
•changes in Consumers' environmental compliance costs
•the purchase or sale of allowances
Greenhouse Gases: There have been numerous legislative and regulatory initiatives at the state, regional, national, and international levels that involve the potential regulation and reporting of greenhouse gases. Consumers continues to monitor and comment on these initiatives, as appropriate.
In May 2023, the EPA released its proposed rule to address greenhouse gas emissions from existing fossil-fuel-fired electric generating units. Under its Clean Energy Plan, Consumers will eliminate the use of coal-fueled generation in 2025. Therefore, this proposed rule will not materially impact Consumers over the remaining operating lives of these coal-fueled facilities. The proposed rule had requirements for existing natural gas-fueled facilities that could have had a material impact on Consumers' natural gas-fueled facilities. However, the EPA announced in March 2024 that the final rule, expected in April or May 2024, will not cover existing natural gas-fueled facilities. Instead, the EPA expects to cover those facilities in a future rulemaking. Consumers will continue to follow the finalization of this rule and any subsequent rules to control greenhouse gases and will continue to evaluate potential impacts to its Clean Energy Plan.
Under the Paris Agreement, an international agreement addressing greenhouse gas emissions, the U.S. has committed to reduce greenhouse gas emissions by 50 to 52 percent from 2005 levels by 2030. Under its Clean Energy Plan, Consumers plans to reduce carbon emissions from its electric business by 60 percent from 2005 levels in 2025. At this time, Consumers does not expect any adverse changes to its environmental strategy as a result of this event, as its plans exceed the nationally committed reduction. The commitment made by the U.S. is not binding without new Congressional legislation.
In 2020, Michigan's Governor signed an executive order creating the Michigan Healthy Climate Plan, which outlines goals for Michigan to achieve economy-wide net-zero greenhouse gas emissions and to be carbon neutral by 2050. The executive order aims for a 28‑percent reduction below 2005 levels of greenhouse gas emissions by 2025. Consumers has already surpassed the 28‑percent reduction milestone for its owned electric generation and previously announced a goal of achieving net-zero carbon emissions from its electric business by 2040. The 2023 Energy Law codifies much of the Governor's goals. For additional details on the 2023 Energy Law, see the Planet section of the Executive Overview.
Increased frequency or intensity of severe or extreme weather events, including those due to climate change, could materially impact Consumers' facilities, energy sales, and results of operations. Consumers is unable to predict these events; however, Consumers evaluates the potential physical impacts of climate change on its operations, including increased frequency or intensity of storm activity; increased precipitation; increased temperature; and changes in lake and river levels. Consumers released a report addressing the physical risks of climate change on its infrastructure in 2022. Consumers is taking steps to mitigate these risks as appropriate.

Question: How does Fortinet address dependency on third-party channel partners?

Fortinet addresses its dependency on third-party channel partners through several strategies to mitigate potential risks. The company relies on channel partners, including distributors and resellers, for a significant portion of its revenue. To manage the risks associated with this dependency, Fortinet has developed specific programs designed to assist and incentivize these partners in selling its products. These programs aim to maintain strong relationships with partners and ensure their motivation to prioritize Fortinet's solutions over competitors' offerings.

Additionally, Fortinet monitors its channel partners' financial health, as a small number of them represent a large percentage of the company's revenue and accounts receivable. This concentration exposes Fortinet to credit and liquidity risks. The company has established measures to manage these risks, including closely monitoring credit terms and partner performance. However, Fortinet acknowledges that these measures may not always fully mitigate the risks. If a significant channel partner fails to perform, reduces its focus on Fortinet’s products, or experiences financial difficulties, it could adversely impact the company’s sales and operating results

Fortinet, Inc. 10-Q form for quarterly period ended 2024-06-30, page 47: contractor, significant subcontractor or key supplier experience financial problems or other problems during the design or construction process, we could experience significant delays, increased costs to complete the project and/or other negative impacts to our expected returns.
We have broad insurance programs covering our properties and operating activities with limits of liability, deductibles and self-insured retentions that we believe are comparable to similarly situated companies. We believe the policy specifications and insured limits of these policies are adequate and appropriate. There are, however, certain types of extraordinary losses which may not be adequately covered under our insurance program. In addition, we could sustain losses due to insurance deductibles, self-insured retention, uninsured claims or casualties or losses in excess of applicable coverage. If an uninsured loss or a loss in excess of insured limits occurs, we could lose all or a portion of the capital we have invested in a property, as well as the anticipated future revenue from the property. In such an event, we might nevertheless remain obligated for any mortgage debt or other financial obligations related to the property. Material losses in excess of insurance proceeds may occur in the future. Such events could materially and adversely affect our financial condition and results of operations.
Additionally, under various federal, state and local environmental laws, ordinances and regulations, a current or previous owner or operator of real property may be liable for the costs of removal or remediation of hazardous or toxic substances on, under or in that property. Those laws often impose liability even if the owner or operator did not cause or know of the presence of hazardous or toxic substances and even if the storage of those substances was in violation of a customer's lease. In addition, the presence of hazardous or toxic substances, or the failure of the owner to address their presence on the property, may adversely affect the owner's ability to borrow using that real property as collateral. Any environmental issues related to our real estate activities could materially and adversely affect our financial condition and results of operations.
We are dependent on the continued services and performance of our senior management, the loss of any of whom could adversely affect our business, operating results and financial condition.
Our future performance depends on the continued services and continuing contributions of our senior management to execute on our business plan and to identify and pursue new opportunities and product innovations. The loss of services of members of senior management, particularly Ken Xie, our Co-Founder, Chief Executive Officer and Chairman, or Michael Xie, our Co-Founder, President and Chief Technology Officer, or of any of our senior sales leaders or functional area leaders, could significantly delay or prevent the achievement of our development and strategic objectives. The loss of the services or the distraction of our senior management for any reason could adversely affect our business, financial condition and results of operations.
We rely on third-party channel partners for substantially all of our revenue. If our partners fail to perform, our ability to sell our products and services will be limited, and if we fail to optimize our channel partner model going forward, our operating results may be harmed. Additionally, a small number of distributors represents a large percentage of our revenue and accounts receivable, and one distributor accounted for 30% of our total net accounts receivable as of June 30, 2024.

A significant portion of our sales is generated through a limited number of distributors, and substantially all of our revenue is from sales by our channel partners, including distributors and resellers. We depend on our channel partners to generate a significant portion of our sales opportunities and to manage our sales process. To the extent our channel partners are unsuccessful in selling our products, or if we are unable to enter into arrangements with and retain a sufficient number of high-quality channel partners in each of the regions in which we sell products, we are unable to keep them motivated to sell our products, or our channel partners shift focus to other vendors and/or our competitors, our ability to sell our products and operating results may be harmed. The termination of our relationship with any significant channel partner may adversely impact our sales and operating results. If we change our partner strategy, such as if we start engaging in more sales directly with customers, and if we terminate partners or partners terminate or reduce selling on our behalf based on changes in our strategy or for any other reason, this could harm our results.
In addition, a small number of channel partners represents a large percentage of our revenue and gross accounts receivable. We are exposed to the credit and liquidity risk of some of our channel partners and to credit exposure in weakened markets, which could result in material losses. Our dependence on a limited number of key channel partners means that our billings, revenue and operating results may be harmed by the inability of these key channel partners to successfully sell our products and services, or if any of these key channel partners is unable or unwilling to pay us, terminates its relationship with us or goes out of business. Although we have programs in place that are designed to monitor and mitigate credit and liquidity risks, we cannot guarantee these programs will be effective in reducing our credit risks. If we are unable to adequately control these risks, our business, operating results, and financial condition could be harmed. If channel partners fail to pay us under the terms of our agreements or we are otherwise unable to collect on our accounts receivable from these channel partners, we may be adversely affected both from the inability to collect amounts due and the cost of enforcing the terms of our contracts, including litigation. Our channel partners may seek bankruptcy protection or other similar relief and fail to pay amounts due to us, or pay those amounts more slowly, either of which could adversely affect our operating results, financial position, and cash flow. We may be further impacted by consolidation of our existing channel partners. In such instances, we may experience
