> MKS Instruments removed one risk related to registration rights while maintaining 28 existing risk disclosures and substantively modifying five key risks, with no new risks added. The most significant modifications addressed personnel retention challenges, increased debt obligations from the Atotech Acquisition, and heightened financial covenants under the company's Term Loan and Revolving Facility agreements. These changes reflect MKS's shifting risk profile following the Atotech acquisition, which substantially increased indebtedness and associated financial constraints.

## No Match in Current: The future exercise of registration rights may adversely affect the market price of our common stock.

*This section from the 2023 filing does not have a high-confidence textual match in 2024. It may have been removed, merged, or substantially reworded.*

In connection with the Atotech Acquisition, we entered into an agreement (the "Investor Rights Agreement") with Carlyle Partners VI Cayman Holdings L.P., CEP IV Participations S.A.R.L Sicar and Gamma Holding Company Limited (collectively, the "Carlyle Shareholders") to grant the Carlyle Shareholders certain registration rights with respect to the shares of our common stock they received upon consummation of the Atotech Acquisition (the "Company Shares"). As of December 31, 2022, the Carlyle Shareholders beneficially owned approximately 13% of our outstanding common stock. Pursuant to the Investor Rights Agreement, the Carlyle Shareholders have registration rights for the Company Shares, and we filed a resale "shelf" registration statement to register such Company Shares and are obligated to use commercially reasonable efforts to keep such registration statement effective thereafter. In addition, and alternatively, shares of common stock that are owned by the Carlyle Shareholders are eligible for sale in the public market to the extent permitted by the provisions of Rule 144 and Rule 701 under the Securities Act of 1933, as amended. If these additional shares of common stock are sold, or if it is perceived that they will be sold, in the public market, the trading price of our common stock could decline. Sales of a substantial number of shares of our common stock pursuant to the resale registration statement in the public market could occur at any time the registration statement remains effective. In addition, the Carlyle Shareholders can request underwritten offerings to sell their securities. These sales, or the perception in the market that the holders of a large number of shares intend to sell shares, could reduce the market price of our common stock.

## Modified: Key personnel have been, and may continue to be, difficult to attract and retain.

**Key changes:**

- Reworded sentence: "Our ability to maintain and grow our business is directly related to the service of our employees, who we consider to be a significant asset."
- Reworded sentence: "There is significant competition for personnel in the technology and sciences marketplace, particularly in certain geographies where we are located, including the Boston area, Orange County and the San Francisco Bay area of California, China, Germany, Japan and Singapore."
- Added sentence: "Bagshaw, our Executive Vice President, Chief Financial Officer and Treasurer, will retire from these positions on April 1, 2024, and as of February 27, 2024, we had yet to appoint his replacement."
- Reworded sentence: "If we are unable to hire sufficient numbers of qualified employees or retain and motivate existing employees, our business and operating results would be harmed."

**Prior (2023):**

Our ability to maintain and grow our business is directly related to the service of our employees in each area of our business, as we consider talent to be a significant asset. Our performance is directly tied to our ability to hire, train, motivate and retain qualified personnel, including highly skilled technical, financial, managerial, and sales and marketing personnel. There is significant competition for personnel in the technology and sciences marketplace, particularly in certain geographies where we are located, including the Boston area, the Orange County, California area, the San Francisco Bay area, China, Germany, Japan and Singapore. Also, employees in our industries are increasingly able to work remotely, which could increase employee mobility and turnover, making it more difficult for us to attract and retain employees. In addition, many of our product manufacturing processes and product services require deep technical expertise, and it can be particularly challenging to identify and attract candidates and retain employees possessing such expertise. We have experienced, and may continue to experience, attrition in certain key positions. A related challenge is that a significant portion of our technical talent is nearing retirement age, and we may have difficulty attracting a sufficient number of employees with the necessary skills to replace them. If we are unable to hire sufficient numbers of qualified employees or retain and motivate existing employees, including our employees from the Atotech Acquisition, our business and operating results would be harmed.

## Modified: The terms of our Term Loan Facility and Revolving Facility impose significant financial obligations and risks upon us, limit our ability to take certain actions, and could discourage a change in control.

**Key changes:**

- Reworded sentence: "As of December 31, 2023, the total principal balance of our USD Tranche A was $744 million, the total principal balance of our USD Tranche B was $3.6 billion and the total principal balance of our Euro Tranche B was €593 million."
- Reworded sentence: "The ratings of our indebtedness reflect each nationally recognized statistical rating organization's opinion of our financial strength, operating performance and ability to meet our debt obligations."
- Reworded sentence: "Our Term Loan Facility and Revolving Facility contain several negative covenants that, among other things and subject to certain exceptions, restrict our ability and/or our subsidiaries' ability to: •Incur additional indebtedness; Incur additional indebtedness; •Pay certain dividends on our capital stock or redeem, repurchase or retire certain capital stock or certain other indebtedness; Pay certain dividends on our capital stock or redeem, repurchase or retire certain capital stock or certain other indebtedness; •Make certain investments, loans and acquisitions; Make certain investments, loans and acquisitions; •Engage in certain transactions with our affiliates; Engage in certain transactions with our affiliates; •Sell assets, including capital stock of our subsidiaries; Sell assets, including capital stock of our subsidiaries; •Materially alter the business we conduct; Materially alter the business we conduct; •Consolidate or merge; Consolidate or merge; •Incur liens; and Incur liens; and •Engage in sale-leaseback transactions."
- Reworded sentence: "In addition, our Revolving Facility requires that we meet a financial covenant based on a consolidated leverage ratio test in certain circumstances."
- Reworded sentence: "Our Term Loan Facility and Revolving Facility contain customary events of default, including: •Failure to make required payments; Failure to make required payments; •Failure to comply with certain agreements or covenants; Failure to comply with certain agreements or covenants; •Materially breaching any representation or warranty; Materially breaching any representation or warranty; •Failure to pay, or cause acceleration of, certain other indebtedness; Failure to pay, or cause acceleration of, certain other indebtedness; •Certain events of bankruptcy and insolvency; Certain events of bankruptcy and insolvency; •Failure to pay certain judgments; and Failure to pay certain judgments; and 16 16 •A change in control of us."

**Prior (2023):**

As of December 31, 2022, the total principal balance of our USD Tranche A was $889 million, the total principal balance of our USD Tranche B was $3,591 million and the total principal balance of our Euro Tranche B was EUR 585 million. Our New Revolving Facility provides us with a senior secured revolving credit facility of up to $500 million. We have not borrowed against our New Revolving Facility as of December 31, 2022. 15 All amounts outstanding under the New Term Loan Facility and the New Revolving Facility bear interest at a variable interest rate. Although we hedge some of the variable interest rate exposure, if interest rates increase, variable rate debt will create higher debt service requirements, which would adversely affect our cash flows. In addition, changes in our credit ratings could affect the cost and availability of future borrowings and, accordingly, our cost of capital. The ratings of our indebtedness reflect each nationally recognized statistical rating organization's opinion of our financial strength, operating performance and ability to meet our debt obligations. We cannot make any assurances that we will achieve or maintain a particular rating in the future. Our New Term Loan Facility and New Revolving Facility contain several negative covenants that, among other things and subject to certain exceptions, restrict our ability and/or our subsidiaries' ability to: •Incur additional indebtedness; Incur additional indebtedness; •Pay certain dividends on our capital stock or redeem, repurchase or retire certain capital stock or certain other indebtedness; Pay certain dividends on our capital stock or redeem, repurchase or retire certain capital stock or certain other indebtedness; •Make certain investments, loans and acquisitions; Make certain investments, loans and acquisitions; •Engage in certain transactions with our affiliates; Engage in certain transactions with our affiliates; •Sell assets, including capital stock of our subsidiaries; Sell assets, including capital stock of our subsidiaries; •Materially alter the business we conduct; Materially alter the business we conduct; •Consolidate or merge; Consolidate or merge; •Incur liens; and Incur liens; and •Engage in sale-leaseback transactions. Engage in sale-leaseback transactions. In addition, the USD Tranche A and the New Revolving Facility require that we meet certain financial covenants based on a consolidated leverage ratio test. Under the USD Tranche A and the New Revolving Facility, so long as any loans under the USD Tranche A (or commitments in respect thereof) are outstanding, our total net leverage ratio cannot exceed 5.50 to 1.00, with an annual step-down of 0.25:1.00 and subject to a step-up of 0.50:1.00 for the four full fiscal quarter period following any material acquisition, not to exceed 5.50 to 1.00. In addition, whenever there are no loans under the USD Tranche A (or commitments in respect thereof) outstanding and the aggregate amount of loans outstanding under the New Revolving Facility (net of (a) all letters of credit (whether cash collateralized or not) and (b) unrestricted cash of us and our restricted subsidiaries) exceeds 35% of the aggregate commitments under the New Revolving Facility, our first lien net leverage ratio cannot exceed 6.00 to 1.00. Our ability to comply with these provisions may be affected by events beyond our control, including prevailing economic, financial and industry conditions. These restrictions on our ability to engage in or benefit from these actions may also limit our flexibility in planning for, or reacting to, changes in and opportunities for our business, such as limiting our ability to engage in mergers and acquisitions. This could place us at a competitive disadvantage. If the matters described in our other risk factors result in a material adverse effect on our business, financial condition or operating results, we may be unable to comply with the terms of our credit facilities or experience an event of default. Our New Term Loan Facility and New Revolving Facility contain customary events of default, including: •Failure to make required payments; Failure to make required payments; •Failure to comply with certain agreements or covenants; Failure to comply with certain agreements or covenants; •Materially breaching any representation or warranty; Materially breaching any representation or warranty; •Failure to pay, or cause acceleration of, certain other indebtedness; Failure to pay, or cause acceleration of, certain other indebtedness; •Certain events of bankruptcy and insolvency; Certain events of bankruptcy and insolvency; •Failure to pay certain judgments; and Failure to pay certain judgments; and •A change in control of us. A change in control of us. The amount of cash available to us for repayment of amounts owed under these credit facilities will depend on our usage of our existing cash balances and our operating performance and ability to generate cash flows from operations, which will be subject to financial, business and other factors affecting our operations, many of which are beyond our control. We cannot provide any assurances that we will generate sufficient cash flows from operations to service our debt obligations. Any failure to repay these obligations as they become due would result in an event of default under the credit facilities. 16 If an event of default occurs, the lenders may end their obligation to make loans to us under the credit facilities and may declare any outstanding indebtedness under these credit facilities immediately due and payable. In such case, we would need to obtain additional financing or significantly deplete our available cash, or both, to repay this indebtedness. Any additional financing may not be available on reasonable terms or at all, and significant depletion of our available cash would harm our ability to fund our operations or execute our broader corporate objectives. If we were unable to repay outstanding indebtedness following an event of default, then in addition to other available rights and remedies, the lenders could initiate foreclosure proceedings on substantially all of our assets. Any such foreclosure proceedings or other rights and remedies successfully implemented by the lenders in an event of default would have a material adverse effect on our business, financial condition and operating results. Further, because a change in control of us constitutes an event of default under these credit facilities, this may be a deterrent to some potential acquirers, as it would likely require an acquirer to repay any outstanding borrowings under these credit facilities.

**Current (2024):**

As of December 31, 2023, the total principal balance of our USD Tranche A was $744 million, the total principal balance of our USD Tranche B was $3.6 billion and the total principal balance of our Euro Tranche B was €593 million. As a result of the USD Tranche A Refinancing, as of January 22, 2024, no principal was outstanding under the USD Tranche A, the total principal balance of our USD Tranche B was $4.1 billion and the total principal balance of our Euro Tranche B was €843 million. As of December 31, 2023, our Revolving Facility provided us with a senior secured revolving credit facility of up to $500 million. As a result of the Revolving Facility Increase, as of February 13, 2024, our Revolving Facility provided us with a senior secured revolving credit facility of up to $675 million. We have not borrowed against our Revolving Facility as of February 13, 2024. All amounts outstanding under the Term Loan Facility and the Revolving Facility bear interest at a variable interest rate. Although we hedge some of the variable interest rate exposure, as interest rates have increased, debt service requirements on our variable rate debt have increased. Further interest rate increases, if they occur and we do not hedge such variable rates, will create higher debt service requirements, which would adversely affect our cash flows. In addition, changes in our credit ratings could affect the cost and availability of future borrowings and, accordingly, our cost of capital. The ratings of our indebtedness reflect each nationally recognized statistical rating organization's opinion of our financial strength, operating performance and ability to meet our debt obligations. We cannot make any assurances that we will achieve or maintain a particular rating in the future. Our Term Loan Facility and Revolving Facility contain several negative covenants that, among other things and subject to certain exceptions, restrict our ability and/or our subsidiaries' ability to: •Incur additional indebtedness; Incur additional indebtedness; •Pay certain dividends on our capital stock or redeem, repurchase or retire certain capital stock or certain other indebtedness; Pay certain dividends on our capital stock or redeem, repurchase or retire certain capital stock or certain other indebtedness; •Make certain investments, loans and acquisitions; Make certain investments, loans and acquisitions; •Engage in certain transactions with our affiliates; Engage in certain transactions with our affiliates; •Sell assets, including capital stock of our subsidiaries; Sell assets, including capital stock of our subsidiaries; •Materially alter the business we conduct; Materially alter the business we conduct; •Consolidate or merge; Consolidate or merge; •Incur liens; and Incur liens; and •Engage in sale-leaseback transactions. Engage in sale-leaseback transactions. In addition, our Revolving Facility requires that we meet a financial covenant based on a consolidated leverage ratio test in certain circumstances. Under our Revolving Facility, whenever the aggregate amount of loans outstanding under the Revolving Facility (net of (a) all letters of credit (whether cash collateralized or not) and (b) unrestricted cash of us and our restricted subsidiaries) exceeds 35% of the aggregate commitments under the Revolving Facility, our first lien net leverage ratio cannot exceed 6.00 to 1.00. Our ability to comply with these provisions may be affected by events beyond our control, including prevailing economic, financial and industry conditions. These restrictions on our ability to engage in or benefit from these actions may also limit our flexibility in planning for, or reacting to, changes in and opportunities for our business, such as limiting our ability to engage in mergers and acquisitions.

## Modified: Our consolidated indebtedness has increased substantially as a result of the Atotech Acquisition. This increased level of indebtedness could adversely affect us, including by increasing our interest expense and decreasing our business flexibility.

**Key changes:**

- Reworded sentence: "As of December 31, 2023, we had approximately $5.0 billion of principal indebtedness outstanding under a senior secured term loan facility (the "Term Loan Facility") comprised of three tranches: a $744 million loan (the "USD Tranche A"), a $3.6 billion loan (the "USD Tranche B") and a €593 million loan (the "Euro Tranche B")."

**Prior (2023):**

As of December 31, 2022, we had approximately $5.1 billion of principal indebtedness outstanding under a senior secured term loan facility (the "New Term Loan Facility") comprised of three tranches: a $1.0 billion loan (the "USD Tranche A"), a $3.6 billion loan (the "USD Tranche B") and a EUR 600 million loan (the "Euro Tranche B"). We also have $500 million of available borrowing capacity under a senior secured revolving credit facility (the "New Revolving Facility" and, together with the New Term Loan Facility, the "New Credit Facilities"). This level of indebtedness could have the effect, among other things, of reducing our flexibility to respond to changing business, industry and economic conditions, limiting our ability to obtain financing in the future and increasing interest expense. We also have incurred and will continue to incur various costs and expenses associated with our indebtedness. The amount of cash required to pay interest on our increased indebtedness levels following completion of the Atotech Acquisition, and the demands on our cash resources that come from that debt, are significantly greater than the amount of cash flows required to service the levels of indebtedness we incurred prior to the Atotech Acquisition. Our increased levels of indebtedness following completion of the Atotech Acquisition could also reduce funds available for working capital, capital expenditures, acquisitions and other general corporate purposes and may create competitive disadvantages relative to other companies with lower debt levels. If we do not achieve the expected benefits and cost savings from the Atotech Acquisition, or if the financial performance of the combined company does not meet current expectations, then our ability to service our indebtedness may be adversely impacted. Despite our current level of indebtedness, we and our subsidiaries may still be able to incur more indebtedness. Although our debt agreements contain restrictions on the incurrence of additional indebtedness, these restrictions are subject to certain qualifications and exceptions, and thus, additional indebtedness may be incurred in compliance with these restrictions. This could further exacerbate the risks we describe. Moreover, we may be required to raise substantial additional financing to fund working capital, capital expenditures, acquisitions or other general corporate requirements. Our ability to arrange additional financing or refinancing will depend on, among other factors, our financial position and performance, as well as prevailing market conditions and other factors beyond our control. There can be no assurance that we will be able to obtain additional financing or refinancing on terms acceptable to us or at all.

**Current (2024):**

As of December 31, 2023, we had approximately $5.0 billion of principal indebtedness outstanding under a senior secured term loan facility (the "Term Loan Facility") comprised of three tranches: a $744 million loan (the "USD Tranche A"), a $3.6 billion loan (the "USD Tranche B") and a €593 million loan (the "Euro Tranche B"). As of December 31, 2023, we also had $500 million of available borrowing capacity under a senior secured revolving credit facility (the "Revolving Facility" and together with the Term Loan Facility, the "Credit Facilities"). On January 22, 2024, we (i) increased our USD Tranche B by an aggregate principal amount of $490 million, (ii) increased our Euro Tranche B by an aggregate principal amount of €250 million and (iii) used a portion of the proceeds of such increases to prepay our USD Tranche A in full (the "USD Tranche A Refinancing"). On February 13, 2024, we increased the available borrowing capacity under our Revolving Facility by $175 million (the "Revolving Facility Increase"). As a result of the USD Tranche A Refinancing, as of January 22, 2024, we had approximately $5.0 billion of principal indebtedness under our Term Loan Facility comprised of a $4.1 billion USD Tranche B and a €843 million Euro Tranche B. As a result of the Revolving Facility Increase, as of February 13, 2024, we had $675 million of available borrowing capacity under our Revolving Facility. This level of indebtedness could have the effect, among other things, of reducing our flexibility to respond to changing business, industry and economic conditions, limiting our ability to obtain financing in the future and increasing interest expense. We also have incurred and will continue to incur various costs and expenses associated with our indebtedness. The amount of cash required to pay interest on our increased indebtedness levels following completion of the Atotech Acquisition, and the demands on our cash resources that come from that debt, are significantly greater than the amount of cash flows required to service the levels of indebtedness we incurred prior to the Atotech Acquisition.

## Modified: Changes in tax rates or tax regulation or the termination of tax incentives could affect our operating results.

**Key changes:**

- Reworded sentence: "Our future annual and quarterly effective tax rates could be materially affected by numerous factors, including changes in the following: applicable tax laws; the organizational structure of our business, including reorganizations, location of assets and outstanding indebtedness; composition of pre-tax income in countries with differing tax rates; our determinations of tax liabilities; and/or valuation of our deferred tax assets and liabilities."
- Reworded sentence: "Many jurisdictions, including many EU countries, have enacted certain provisions of the GloBE rules effective as of January 1, 2024."
- Reworded sentence: "If we fail to qualify or remain qualified for certain tax incentives, the tax incentives we previously received may be terminated and/or retroactively revoked, requiring repayment of past tax benefits, and we would be subject to an increase in our effective tax rate, which could have a materially adverse impact our financial results."

**Prior (2023):**

As a global company, we are subject to taxation in the United States and various other countries. Significant judgment is required to determine and estimate worldwide tax liabilities. Our future annual and quarterly effective tax rates could be affected by numerous factors, including changes in the applicable tax laws; composition of pre-tax income in countries with differing tax rates; our determinations of tax liabilities; and/or valuation of our deferred tax assets and liabilities. The enactment of the Tax Cuts and Jobs Act (the "TCJA") in December 2017 significantly affected U.S. tax law by changing how the United States imposes tax on multinational corporations. The U.S. Department of Treasury has broad authority under the TCJA to issue regulations and interpretive guidance. Some of the proposed and final regulations that have been issued regarding the TCJA have been challenged in court. We have applied available guidance to estimate our tax obligations, but new guidance issued by the U.S. Treasury Department may cause us to adjust our tax estimates in future periods. The ultimate impact of the TCJA on our U.S. tax liabilities is based upon our understanding and interpretation of the regulatory guidance that has been issued regarding the TCJA. On October 4, 2021, 136 members of the Organisation for Economic Co-operation and Development ("OECD") agreed to a global minimum tax rate of 15%. On December 20, 2021, OECD published its model rules on the agreed minimum tax known as the Global Anti-Base Erosion ("GloBE") rules. The GloBE rules provide a framework for a coordinated multi-country system of taxation intended to ensure large multinational enterprise groups pay a minimum level of tax on the income arising in each of the jurisdictions where they operate. On December 14, 2022, the European Council approved its directive to implement Pillar Two of the GloBE rules regarding a 15% global minimum tax rate. Many EU countries have already indicated they plan to enact certain provisions of this directive as of January 1, 2024. In addition, many G20 nations have indicated their plan to follow the OECD guidance as early as January 1, 2024. Pillar Two may materially increase our future effective tax rate. We are subject to regular examination by the U.S. Internal Revenue Service and state, local and foreign tax authorities. We regularly assess the likelihood of favorable or unfavorable outcomes resulting from these examinations to determine the adequacy of our provision for income taxes. Although we believe our tax estimates are reasonable, we can make no assurances that any final determination of tax liability will not be materially different from the treatment reflected in our historical income tax provisions and accruals, which could materially and adversely affect our financial condition and operating results. We qualify for tax incentives based on our ability to meet, on a continuing basis, various tests relating to our employment levels, research and development expenditures and other qualification requirements in a particular jurisdiction. While we intend to operate in such a manner to maintain and maximize our tax incentives, we can make no assurances that we have so qualified or that we will so qualify for any particular year or jurisdiction. If we fail to qualify or remain qualified for certain tax incentives, the tax incentives we previously received may be terminated and/or retroactively revoked, requiring repayment of past tax benefits, and we would be subject to an increase in our effective tax rate, which would adversely impact our financial results.

Changes in U.S. tax law, such as the Tax Cuts and Jobs Act, the Inflation Reduction Act, and changes in regulations and tax guidance may affect our business. Additionally, the United States is considering various corporate and international income tax proposals, which, if enacted, could have a material impact on our provision for income taxes and effective tax rate. Many countries in which we operate are implementing legislation and other tax changes to align their tax systems with the Organisation for Economic Co-operation and Development global minimum tax rate known as Pillar Two of the Global Anti-Base Erosion ("GloBE") rules. The GloBE rules provide a framework for a coordinated multi-country system of taxation intended to ensure large multinational enterprise groups pay a minimum level of tax on the income arising in each of the jurisdictions where they operate.

## Modified: A material amount of our assets represents goodwill and intangible assets. We incurred a net loss as a result of impairments of these assets in 2023 and our net income may be significantly reduced in subsequent periods by future impairments of these assets.

**Key changes:**

- Reworded sentence: "As of December 31, 2023, our goodwill and intangible assets, net, represented approximately $5.2 billion, or 57% of our total assets."
- Reworded sentence: "If market and economic conditions or business performance deteriorate, the likelihood that we would record another impairment charge would increase."

As of December 31, 2022, our goodwill and intangible assets, net, represented approximately $7.5 billion, or 65% of our total assets. Goodwill is generated in our acquisitions when the cost of an acquisition exceeds the fair value of the net tangible and identifiable intangible assets we acquire. For example, as a result of the Atotech Acquisition, we added significant additional goodwill and intangible assets. Goodwill and indefinite-lived intangible assets are subject to an impairment analysis at least annually based on the fair value of the reporting unit. Intangible assets relate primarily to the developed technologies, customer relationships, trade names and trademarks acquired by us as part of our acquisitions of other companies and are subject to an impairment analysis whenever events or changes in circumstances exist that indicate that the carrying value of the intangible asset might not be recoverable. We will continue to monitor and evaluate the carrying value of goodwill and intangible assets. If market and economic conditions or business performance deteriorate, the likelihood that we would record an impairment charge would increase, which impairment charge could materially and adversely affect our financial condition and operating results.

**Current (2024):**

As of December 31, 2023, our goodwill and intangible assets, net, represented approximately $5.2 billion, or 57% of our total assets. Goodwill is generated as a result of our acquisitions when the cost of an acquisition exceeds the fair value of the net tangible and identifiable intangible assets we acquire. For example, as a result of the Atotech Acquisition, we added significant additional goodwill and intangible assets because the cost of the Atotech Acquisition significantly exceeded the fair value of Atotech's net tangible and identifiable intangible assets. Intangible assets relate primarily to the developed technologies, customer relationships, trade names and trademarks acquired by us as part of our acquisitions of other companies. Goodwill and indefinite-lived intangible assets are subject to an impairment analysis at least annually based on the fair value of the reporting unit in which the respective goodwill and intangible assets are recorded. In addition, intangible assets and goodwill are subject to an impairment analysis whenever events or changes in circumstances indicate that the carrying value of the intangible asset might not be recoverable. As described in Note 13 to the Notes to Consolidated Financial Statements, following triggering events at each of our EL and GMF reporting units, which together constitute MSD, and the ESB reporting unit of PSD, we recorded goodwill and intangible asset impairments of $1.8 billion during the quarter ended June 30, 2023 and, following an annual impairment analysis of all our reporting units, we recorded goodwill and intangible asset impairments of $75 million during the quarter ended December 31, 2023. We will continue to monitor and evaluate the carrying value of goodwill and intangible assets. If market and economic conditions or business performance deteriorate, the likelihood that we would record another impairment charge would increase. Any impairment charge could materially and adversely affect our financial condition and operating results, including by significantly reducing our net income in future periods.
