Commitments and Contingencies	18) Commitments and Contingencies Litigation On March 25, 2016, two putative class action lawsuits captioned Dixon Chung v. Newport Corp., et al., and Hubert C. Pincon v. Newport Corp., et al., were filed in the District Court, Clark County, Nevada on behalf of a putative class of stockholders of Newport for claims related to the merger agreement between the Company, Newport, and a wholly-owned subsidiary of the Company ("Merger Sub"). The lawsuits named as defendants the Company, Newport, Merger Sub, and certain then current and former members of Newport’s board of directors. The lawsuits alleged that Newport’s directors breached their fiduciary duties to Newport’s stockholders in connection with the sale of Newport, which led to inadequate and unfair consideration, by agreeing to unfair deal protection devices and by omitting material information from the proxy statement. The complainants also alleged that the Company, Newport and Merger Sub aided and abetted the directors’ alleged breaches of their fiduciary duties and sought monetary damages, including pre- and post-judgment interest. The District Court consolidated the actions, and plaintiffs filed first amended complaint on October 24, 2016 and a second amended complaint on July 12, 2017, each of which were captioned In re Newport Corporation Shareholder Litigation, and made substantially similar allegations and sought monetary damages, including pre- and post-judgment interest. The District Court denied plaintiffs’ motion for leave to file a third amended complaint on October 10, 2019 and thereafter entered summary judgment for the defendants on January 23, 2020. On March 30, 2022, the Nevada Supreme Court entered an order affirming in their entirety the District Court's orders granting defendants' motion for summary judgment and denying plaintiffs' motion for leave to file an amended complaint. The Company is also subject to various legal proceedings and claims that have arisen in the ordinary course of business. In the opinion of management, the ultimate disposition of these matters will not have a material adverse effect on the Company's results of operations, financial condition or cash flows. Atotech On July 1, 2021, the Company entered into a definitive agreement with Atotech (as amended from time to time, the "Implementation Agreement") to acquire Atotech, a leading process chemicals technology company and a market leader in advanced electroplating solutions. Pursuant to the Implementation Agreement, the Company agreed to pay $16.20 per share in cash and 0.0552 of a share of MKS common stock for each outstanding common share of Atotech (the "Atotech Acquisition"). The final value of the consideration will be determined at the time of the closing of the Atotech Acquisition, which is subject to obtaining the required sanction by the Royal Court of Jersey and the satisfaction of customary closing conditions. The Company's obligation to complete the Atotech Acquisition is not subject to any financing condition. The Company intends to fund the cash portion of the transaction with a combination of available cash on hand and committed term loan debt financing. In connection with entering into the Implementation Agreement, the Company entered into (a) a debt commitment letter, dated as of July 1, 2021, with JPMorgan Chase Bank, N.A. and Barclays Bank PLC (the "Commitment Parties") and (b) joinders to such commitment letter to add certain additional lender parties (together with the Commitment Parties, the "2021 Commitment Parties") dated as of July 23, 2021 ((a) and (b) together, the "2021 Commitment Letter"), pursuant to which, subject to the terms and conditions set forth therein, the 2021 Commitment Parties committed to provide (i) a senior secured term loan credit facility in an aggregate principal amount of $5,300, which would refinance the Term Loan Facility and be used to finance a portion of the Atotech Acquisition and refinance certain existing indebtedness of Atotech and (ii) a senior secured revolving credit facility with aggregate total commitments of $500, which would replace the ABL Facility. On April 1, 2022, the Company entered into an amendment to the Implementation Agreement (the "Amendment"), providing for additional time for the satisfaction of certain closing conditions set forth in the Implementation Agreement, including approval of the Atotech Acquisition by the Royal Court of Jersey and receipt of regulatory approvals ("Clearances"), such that the Long Stop Date (as defined in the Implementation Agreement) was extended from March 31, 2022 to September 30, 2022. In addition, the Amendment amended certain provisions related to obtaining the Clearances, the timing of the closing date and the obligations of the parties with respect to the debt financing contemplated in connection with the Atotech Acquisition and provides for the automatic termination of the Implementation Agreement if the closing has not occurred by the Long Stop Date. In connection with the Amendment, the Company terminated the 2021 Commitment Letter and entered into (a) a new debt commitment letter, dated as of April 1, 2022, with the Commitment Parties and (b) joinders to such commitment letter to add certain additional lender parties (together with the Commitment Parties, the "2022 Commitment Parties") dated as of April 4, 2022 ((a) and (b) together, the "2022 Commitment Letter"), pursuant to which, among other things, the 2022 Commitment Parties committed to provide the Company with (i) a senior secured term loan B credit facility consisting of a $4,250 term loan B and (ii) a senior secured term loan A credit facility consisting of a $1,000 term loan A ((i) and (ii) together, the "2022 New Term Loan Facilities") and (iii) a senior secured revolving credit facility with aggregate total commitments of $500 (the "2022 New Revolving Credit Facility"). The 2022 New Term Loan Facilities and the 2022 New Revolving Credit Facility would replace the Term Loan Facility and the ABL Facility, respectively, be used to finance a portion of the Atotech Acquisition, to refinance certain existing indebtedness of Atotech, to pay fees and expenses in connection with the Atotech Acquisition, and, in the case of the 2022 New Revolving Credit Facility, be used for working capital and for general corporate purposes. On April 11, 2022, in connection with the 2022 Commitment Letter, the Company completed the syndication of the 2022 New Term Loan Facilities, comprised of (i) two tranches of term loan B: a tranche of $3,600 at the secured overnight financing rate ("SOFR") plus 2.75%, a floor of 0.50% and 2.0% of original issue discount ("OID"), and a Euro tranche of EUR 600 at EURIBOR plus 3.00%, a floor of 0.00% and 2.00% of OID; and (ii) a $1,000 term loan A at SOFR plus 2.50%, a floor of 0.00% and 0.25% of OID. The 2022 Commitment Parties' obligations under the 2022 Commitment Letter and the closing and initial funding under the 2022 New Term Loan Facilities and the 2022 New Revolving Credit Facility are subject to certain customary conditions including, without limitation, the consummation of the Atotech Acquisition in accordance with the Implementation Agreement, the accuracy of specified representations and warranties of the Company and other customary closing conditions.

Pursuant to the Implementation Agreement, the Company agreed to pay $16.20 per share in cash and 0.0552 of a share of MKS common stock for each outstanding common share of Atotech (the "Atotech Acquisition").
