Contingent Liabilities and Other Matters	12 Months Ended
Dec. 31, 2019
Commitments and Contingencies Disclosure [Abstract]
Contingent Liabilities and Other Matters	Contingent Liabilities and Other Matters Spin-Off of SPX FLOW In connection with the Spin-Off, we entered into definitive agreements with SPX FLOW that, among other matters, set forth the terms and conditions of the Spin-Off and provide a framework for our relationship with SPX FLOW after the Spin-Off, including the following: •Separation and Distribution Agreement; •Tax Matters Agreement; •Employee Matters Agreement; and •Trademark License Agreement. Pursuant to the Separation and Distribution Agreement, the Employee Matters Agreement and the Tax Matters Agreement, SPX FLOW has agreed to indemnify us for certain liabilities, and we have agreed to indemnify SPX FLOW for certain liabilities, in each case for uncapped amounts. As of December 31, 2019, no material indemnification claims have been initiated. The financial activity governed by these agreements between SPX FLOW and us was not material to our consolidated financial results for the years ended December 31, 2019, 2018 and 2017. We also entered into a five-year agreement with SPX FLOW to lease office space for our corporate headquarters. Annual lease costs associated with the agreement are $2.1. This agreement expires in September, 2020. General Numerous claims, complaints and proceedings arising in the ordinary course of business have been asserted or are pending against us or certain of our subsidiaries (collectively, “claims”). These claims relate to litigation matters (e.g., class actions, derivative lawsuits and contracts, intellectual property and competitive claims), environmental matters, product liability matters (predominately associated with alleged exposure to asbestos-containing materials), and other risk management matters (e.g., general liability, automobile, and workers’ compensation claims). Additionally, we may become subject to other claims of which we are currently unaware, which may be significant, or the claims of which we are aware may result in our incurring significantly greater loss than we anticipate. While we (and our subsidiaries) maintain property, cargo, auto, product, general liability, environmental, and directors’ and officers’ liability insurance and have acquired rights under similar policies in connection with acquisitions that we believe cover a significant portion of these claims, this insurance may be insufficient or unavailable (e.g., in the case of insurer insolvency) to protect us against potential loss exposures. Also, while we believe we are entitled to indemnification from third parties for some of these claims, these rights may be insufficient or unavailable to protect us against potential loss exposures. Our recorded liabilities related to these matters totaled $592.4 (including $552.2 for asbestos product liability matters) and $631.7 (including $587.5 for asbestos product liability matters) at December 31, 2019 and 2018, respectively. Of these amounts, $517.6 and $600.3 are included in “Other long-term liabilities” within our consolidated balance sheets at December 31, 2019 and 2018, respectively, with the remainder included in “Accrued expenses.” The liabilities we record for these claims are based on a number of assumptions, including historical claims and payment experience and, with respect to asbestos claims, actuarial estimates of the future period during which additional claims are reasonably foreseeable. While we base our assumptions on facts currently known to us, they entail inherently subjective judgments and uncertainties. As a result, our current assumptions for estimating these liabilities may not prove accurate, and we may be required to adjust these liabilities in the future, which could result in charges to earnings. These variances relative to current expectations could have a material impact on our financial position and results of operations. Our asbestos-related claims are typical in certain of the industries in which we operate or pertain to legacy businesses we no longer operate. It is not unusual in these cases for fifty or more corporate entities to be named as defendants. We vigorously defend these claims, many of which are dismissed without payment, and the significant majority of costs related to these claims have historically been paid pursuant to our insurance arrangements. During the years ended December 31, 2019, 2018 and 2017, our payments for asbestos-related matters, net of respective insurance recoveries of $47.1, $45.3, and $57.3, were $13.1, $9.7 and $1.0, respectively. A significant increase in claims, costs and/or issues with existing insurance coverage (e.g., dispute with or insolvency of insurer(s)) could have a material adverse impact on our share of future payments related to these matters, and, as a result, have a material impact on our financial position, results of operations and cash flows. We have recorded insurance recovery assets associated with the asbestos product liability matters, with such amounts totaling $509.6 and $541.9 at December 31, 2019 and 2018, respectively. Of these amounts, $459.6 and $541.9 are included in “Other assets” within our consolidated balance sheets at December 31, 2019 and 2018, respectively, with the remainder included in “Other current assets.” These assets represent amounts that we believe we are or will be entitled to recover under agreements we have with insurance companies. The assets we record for these insurance recoveries are based on a number of assumptions, including the continued solvency of the insurers and our legal interpretation of our rights for recovery under the agreements we have with the insurers. Our current assumptions for estimating these assets may not prove accurate, and we may be required to adjust these assets in the future. These variances relative to current expectations could have a material impact on our financial position and results of operations. During the years ended December 31, 2019, 2018, and 2017, we recorded charges of $8.3, $2.4, and $5.7, respectively, as a result of changes in estimates associated with the liabilities and assets related to asbestos product liability matters. Of these charges, $4.5, $2.0 and $3.5 were recorded to “Other expense, net” for the years ended December 31, 2019, 2018, and 2017, respectively, and $3.8, $0.4, and $2.2, respectively, to “Gain (loss) on disposition of discontinued operations, net of tax.” Large Power Projects in South Africa Overview - Since 2008, DBT has been executing contracts on two large power projects in South Africa (Kusile and Medupi). Over such time, the business environment surrounding these projects has been difficult, as DBT, along with many other contractors on the projects, have experienced delays, cost over-runs, and various other challenges associated with a complex set of contractual relationships among the end customer, prime contractors, various subcontractors (including DBT and its subcontractors), and various suppliers. DBT has substantially completed its scope of work, with its remaining responsibilities related largely to resolution of various claims, primarily between itself and one of its prime contractors, Mitsubishi-Hitachi Power Systems Africa (PTY) LTD (“MHPSA”). The challenges related to the projects have resulted in (i) significant adjustments to our revenue and cost estimates for the projects, (ii) DBT’s submission of numerous change orders to the prime contractors, (iii) various claims and disputes between DBT and other parties involved with the projects (e.g., prime contractors, subcontractors, suppliers, etc.), and (iv) the possibility that DBT may become subject to additional claims, which could be significant. It is possible that some outstanding claims may not be resolved until after the prime contractors complete their scopes of work. Our future financial position, operating results, and cash flows could be materially impacted by the resolution of current and any future claims. Claims by DBT - DBT has made numerous claims against MHPSA, including claims totaling South African Rand 1,133.3 (or $80.8) that have been submitted to dispute adjudication processes as required under the relevant contracts, with such amount subject to change as DBT progresses through these processes. Certain of these processes are expected to occur in 2020. In addition to existing asserted claims, DBT may have additional claims and rights to recovery based on its remaining performance under the contracts with, and actions taken by, MHPSA. The amounts DBT may recover for current and potential future claims against MHPSA are not currently known given (i) the extent of current and potential future claims by MHPSA against DBT (see below for further discussion) and (ii) the unpredictable nature of any dispute resolution processes that may occur in connection with these current and potential future claims. No revenue has been recorded in the accompanying consolidated financial statements with respect to current or potential future claims against MHPSA. Claims by Prime Contractors - On February 26, 2019, DBT received notification of an interim claim consisting of both direct and consequential damages from MHPSA alleging, among other things, that DBT (i) provided defective product and (ii) failed to meet certain project milestones. We believe the notification is unsubstantiated and the vast majority of the claimed damages are prohibited under the relevant contracts. Therefore, we believe any loss for the majority of these claimed damages is remote. For the remainder of the claims, which largely appear to be direct in nature (approximately South African Rand 948.0 or $67.6), DBT has numerous defenses and, thus, we do not believe that DBT has a probable loss associated with these claims. As such, no loss has been recorded in the accompanying consolidated financial statements with respect to these claims. Although it is reasonably possible that some loss may be incurred in connection with these claims, we currently are unable to estimate the potential loss or range of potential loss associated with these claims due to the (i) lack of support provided by MPHSA for these claims; (ii) complexity of contractual relationships between the end customer, MHPSA, and DBT; (iii) legal interpretation of the contract provisions and application of South African common law to the contracts; and (iv) unpredictable nature of any dispute resolution processes that may occur in connection with these claims. In April and July 2019, DBT received notifications of intent to claim liquidated damages totaling South African Rand 407.2 (or $29.0) from MHPSA alleging that DBT failed to meet certain project milestones related to the construction of the filters for both the Kusile and Medupi projects. DBT has numerous defenses against these claims and, thus, we do not believe that DBT has a probable loss associated with these claims. As such, no loss has been recorded in the accompanying consolidated financial statements with respect to these claims. Although it is reasonably possible that some loss may be incurred in connection with these claims, we currently are unable to estimate the potential loss or range of potential loss. MHPSA has made other claims against DBT totaling South African Rand 176.2 (or $12.6). DBT has numerous defenses against these claims and, thus, we do not believe that DBT has a probable loss associated with these claims. As such, no loss has been recorded in the accompanying consolidated financial statements with respect to these claims. In favor of MHPSA, we have issued bonds totaling $65.1 (including $23.3 with more stringent payment terms). We believe a portion of these bonds should be reduced based on project milestones achieved by DBT. In the event that MHPSA were to receive payment on a portion, or all, of these bonds, we would be required to reimburse the bank. In addition to these bonds, SPX Corporation has guaranteed DBT’s performance on these projects to the prime contractors. On June 28, 2019, DBT reached an agreement with Alstom/GE, the other prime contractor on the projects, to, among other things, settle all material outstanding claims between the parties (other than certain pass-through claims relating to third parties), including a liquidated damages claim made by Alstom/GE. In connection with the agreement, we reduced revenues (and operating income) by $6.0 during the second quarter of 2019. Claims by Subcontractor - On October 30, 2018, a non-governmental business adjudicator in South Africa provided a decision on certain claims made against DBT by one of its subcontractors. As part of its decision, the adjudicator concluded that the subcontractor was entitled to payment of South African Rand 256.0 (or $18.2). We believed that the decision was invalid on numerous bases and, thus, we did not record a loss in our accompanying consolidated financial statements as a result of the adjudicator’s decision. The matter was referred to an arbitration tribunal and, on January 16, 2020, the arbitration tribunal ruled that the subcontractor was only entitled to a payment of South African Rand 19.4 (or $1.4). The arbitration tribunal’s ruling is binding on both DBT and the subcontractor. We have reflected the liability for such amount within our consolidated balance sheet as of December 31, 2019. Noncontrolling Interest in South African Subsidiary DBT had a Black Economic Empowerment shareholder (the “BEE Partner”) that held a 25.1% noncontrolling interest in DBT. Under the terms of the shareholder agreement between the BEE Partner and SPX Technologies (PTY) LTD (“SPX Technologies”), the BEE Partner had the option to put its ownership interest in DBT to SPX Technologies, the majority shareholder of DBT, at a redemption amount determined in accordance with the terms of the shareholder agreement (the “Put Option”). The BEE Partner notified SPX Technologies of its intention to exercise the Put Option and, on July 6, 2016, an arbitration tribunal declared that the BEE Partner was entitled to South African Rand 287.3 in connection with the exercise of the Put Option, having not considered an amount due from the BEE Partner under a promissory note of South African Rand 30.3 held by SPX Technologies. As a result, beginning in the third quarter of 2016, we reflected the net redemption amount of South African Rand 257.0 (or $17.7 at December 31, 2018) within “Accrued expenses” on our consolidated balance sheet, with the related offset recorded to “Paid-in capital” and “Accumulated other comprehensive income.” In August 2016, SPX Technologies applied to the High Court of South Africa (the “High Court”) to have the arbitration tribunal’s ruling set aside. On January 22, 2018, the High Court ruled in SPX Technologies' favor and set aside the arbitration tribunal’s ruling. The BEE Partner subsequently applied to the Supreme Court of Appeal of South Africa (the “SCA”) to have the arbitration tribunal’s ruling upheld. On September 6, 2019, the SCA ruled in favor of the BEE Partner. On October 16, 2019, SPX Technologies, DBT, and SPX Corporation executed an agreement with the BEE Partner and its affiliates to settle the Put Option and all other claims between the parties for a total payment of South African Rand 230.0 (or $15.6), which was paid in full on October 21, 2019. The difference between the settlement amount (South African Rand 230.0) and the amount previously recorded of South African Rand 257.0 (see above), or South African Rand 27.0 (or $1.8), along with a tax benefit of $3.8 associated with the total payment of South African Rand 230.0, have been reflected as an adjustment to “Net income attributable to SPX common shareholders” in our calculation of basic and diluted earnings per share for the year ended December 31, 2019, with such adjustment totaling $5.6. Litigation Matters We are subject to other legal matters that arise in the normal course of business. We believe these matters are either without merit or of a kind that should not have a material effect, individually or in the aggregate, on our financial position, results of operations or cash flows; however, we cannot give assurance that these proceedings or claims will not have a material effect on our financial position, results of operations or cash flows. Environmental Matters Our operations and properties are subject to federal, state, local and foreign regulatory requirements relating to environmental protection. It is our policy to comply fully with all applicable requirements. As part of our effort to comply, we have a comprehensive environmental compliance program that includes environmental audits conducted by internal and external independent professionals, as well as regular communications with our operating units regarding environmental compliance requirements and anticipated regulations. Based on current information, we believe that our operations are in substantial compliance with applicable environmental laws and regulations, and we are not aware of any violations that could have a material effect, individually or in the aggregate, on our business, financial condition, and results of operations or cash flows. As of December 31, 2019, we had liabilities for site investigation and/or remediation at 29 sites (28 sites at December 31, 2018) that we own or control. In addition, while we believe that we maintain adequate accruals to cover the costs of site investigation and/or remediation, we cannot provide assurance that new matters, developments, laws and regulations, or stricter interpretations of existing laws and regulations will not materially affect our business or operations in the future. Our environmental accruals cover anticipated costs, including investigation, remediation, and operation and maintenance of clean-up sites. Our estimates are based primarily on investigations and remediation plans established by independent consultants, regulatory agencies and potentially responsible third parties. Accordingly, our estimates may change based on future developments, including new or changes in existing environmental laws or policies, differences in costs required to complete anticipated actions from estimates provided, future findings of investigation or remediation actions, or alteration to the expected remediation plans. It is our policy to revise an estimate once it becomes probable and the amount of change can be reasonably estimated. We generally do not discount our environmental accruals and do not reduce them by anticipated insurance recoveries. We take into account third-party indemnification from financially viable parties in determining our accruals where there is no dispute regarding the right to indemnification. In the case of contamination at offsite, third-party disposal sites, as of December 31, 2019, we have been notified that we are potentially responsible and have received other notices of potential liability pursuant to various environmental laws at 14 sites (14 sites at December 31, 2018) at which the liability has not been settled, of which 11 sites have been active in the past few years. These laws may impose liability on certain persons that are considered jointly and severally liable for the costs of investigation and remediation of hazardous substances present at these sites, regardless of fault or legality of the original disposal. These persons include the present or former owners or operators of the site and companies that generated, disposed of or arranged for the disposal of hazardous substances at the site. We are considered a “de minimis” potentially responsible party at most of the sites, and we estimate that our aggregate liability, if any, related to these sites is not material to our consolidated financial statements. We conduct extensive environmental due diligence with respect to potential acquisitions, including environmental site assessments and such further testing as we may deem warranted. If an environmental matter is identified, we estimate the cost and either establish a liability, purchase insurance or obtain an indemnity from a financially sound seller; however, in connection with our acquisitions or dispositions, we may assume or retain significant environmental liabilities, some of which we may be unaware. The potential costs related to these environmental matters and the possible impact on future operations are uncertain due in part to the complexity of government laws and regulations and their interpretations, the varying costs and effectiveness of various clean-up technologies, the uncertain level of insurance or other types of recovery, and the questionable level of our responsibility. We record a liability when it is both probable and the amount can be reasonably estimated. In our opinion, after considering accruals established for such purposes, the cost of remedial actions for compliance with the present laws and regulations governing the protection of the environment is not expected to have a material impact, individually or in the aggregate, on our financial position, results of operations or cash flows. Self-Insured Risk Management Matters We are self-insured for certain of our workers’ compensation, automobile, product and general liability, disability and health costs, and we believe that we maintain adequate accruals to cover our retained liability. Our accruals for risk management matters are determined by us, are based on claims filed and estimates of claims incurred but not yet reported, and generally are not discounted. We consider a number of factors, including third-party actuarial valuations, when making these determinations. We maintain third-party stop-loss insurance policies to cover certain liability costs in excess of predetermined retained amounts. This insurance may be insufficient or unavailable (e.g., because of insurer insolvency) to protect us against loss exposure. Executive Agreements The Board of Directors has approved an employment agreement for our President and Chief Executive Officer. This agreement had an initial term through December 31, 2017 and, thereafter, rolling terms of one year, and specifies the executive’s current compensation, benefits and perquisites, severance entitlements, and other employment rights and responsibilities. The Compensation Committee of the Board of Directors has approved severance benefit agreements for our other six executive officers. These agreements cover each executive’s entitlements in the event that the executive’s employment is terminated for other than cause, death or disability, or the executive resigns with good reason. The Compensation Committee of the Board of Directors has also approved change of control agreements for each of our executive officers, which cover each executive’s entitlements following a change of control.

Numerous claims, complaints and proceedings arising in the ordinary course of business have been asserted or are pending against us or certain of our subsidiaries (collectively, “claims”). These claims relate to litigation matters (e.g., class actions, derivative lawsuits and contracts, intellectual property and competitive claims), environmental matters, product liability matters (predominately associated with alleged exposure to asbestos-containing materials), and other risk management matters (e.g., general liability, automobile, and workers’ compensation claims). Additionally, we may become subject to other claims of which we are currently unaware, which may be significant, or the claims of which we are aware may result in our incurring significantly greater loss than we anticipate. While we (and our subsidiaries) maintain property, cargo, auto, product, general liability, environmental, and directors’ and officers’ liability insurance and have acquired rights under similar policies in connection with acquisitions that we believe cover a significant portion of these claims, this insurance may be insufficient or unavailable (e.g., in the case of insurer insolvency) to protect us against potential loss exposures. Also, while we believe we are entitled to indemnification from third parties for some of these claims, these rights may be insufficient or unavailable to protect us against potential loss exposures.

Our recorded liabilities related to these matters totaled $592.4 (including $552.2 for asbestos product liability matters) and $631.7 (including $587.5 for asbestos product liability matters) at December 31, 2019 and 2018, respectively. Of these amounts, $517.6 and $600.3 are included in “Other long-term liabilities” within our consolidated balance sheets at December 31, 2019 and 2018, respectively, with the remainder included in “Accrued expenses.” The liabilities we record for these claims are based on a number of assumptions, including historical claims and payment experience and, with respect to asbestos claims, actuarial estimates of the future period during which additional claims are reasonably foreseeable. While we base our assumptions on facts currently known to us, they entail inherently subjective judgments and uncertainties. As a result, our current assumptions for estimating these liabilities may not prove accurate, and we may be required to adjust these liabilities in the future, which could result in charges to earnings. These variances relative to current expectations could have a material impact on our financial position and results of operations.

Our asbestos-related claims are typical in certain of the industries in which we operate or pertain to legacy businesses we no longer operate. It is not unusual in these cases for fifty or more corporate entities to be named as defendants. We vigorously defend these claims, many of which are dismissed without payment, and the significant majority of costs related to these claims have historically been paid pursuant to our insurance arrangements. During the years ended December 31, 2019, 2018 and 2017, our payments for asbestos-related matters, net of respective insurance recoveries of $47.1, $45.3, and $57.3, were $13.1, $9.7 and $1.0, respectively. A significant increase in claims, costs and/or issues with existing insurance coverage (e.g., dispute with or insolvency of insurer(s)) could have a material adverse impact on our share of future payments related to these matters, and, as a result, have a material impact on our financial position, results of operations and cash flows.

We have recorded insurance recovery assets associated with the asbestos product liability matters, with such amounts totaling $509.6 and $541.9 at December 31, 2019 and 2018, respectively. Of these amounts, $459.6 and $541.9 are included in “Other assets” within our consolidated balance sheets at December 31, 2019 and 2018, respectively, with the remainder included in “Other current assets.” These assets represent amounts that we believe we are or will be entitled to recover under agreements we have with insurance companies. The assets we record for these insurance recoveries are based on a number of assumptions, including the continued solvency of the insurers and our legal interpretation of our rights for recovery under the agreements we have with the insurers. Our current assumptions for estimating these assets may not prove accurate, and we may be required to adjust these assets in the future. These variances relative to current expectations could have a material impact on our financial position and results of operations.

During the years ended December 31, 2019, 2018, and 2017, we recorded charges of $8.3, $2.4, and $5.7, respectively, as a result of changes in estimates associated with the liabilities and assets related to asbestos product liability matters. Of these charges, $4.5, $2.0 and $3.5 were recorded to “Other expense, net” for the years ended December 31, 2019, 2018, and 2017, respectively, and $3.8, $0.4, and $2.2, respectively, to “Gain (loss) on disposition of discontinued operations, net of tax.”

Overview - Since 2008, DBT has been executing contracts on two large power projects in South Africa (Kusile and Medupi). Over such time, the business environment surrounding these projects has been difficult, as DBT, along with many other contractors on the projects, have experienced delays, cost over-runs, and various other challenges associated with a complex set of contractual relationships among the end customer, prime contractors, various subcontractors (including DBT and its subcontractors), and various suppliers. DBT has substantially completed its scope of work, with its remaining responsibilities related largely to resolution of various claims, primarily between itself and one of its prime contractors, Mitsubishi-Hitachi Power Systems Africa (PTY) LTD (“MHPSA”).

The challenges related to the projects have resulted in (i) significant adjustments to our revenue and cost estimates for the projects, (ii) DBT’s submission of numerous change orders to the prime contractors, (iii) various claims and disputes between DBT and other parties involved with the projects (e.g., prime contractors, subcontractors, suppliers, etc.), and (iv) the possibility that DBT may become subject to additional claims, which could be significant. It is possible that some outstanding claims may not be resolved until after the prime contractors complete their scopes of work. Our future financial position, operating results, and cash flows could be materially impacted by the resolution of current and any future claims.

Claims by DBT - DBT has made numerous claims against MHPSA, including claims totaling South African Rand 1,133.3 (or $80.8) that have been submitted to dispute adjudication processes as required under the relevant contracts, with such amount subject to change as DBT progresses through these processes. Certain of these processes are expected to occur in 2020. In addition to existing asserted claims, DBT may have additional claims and rights to recovery based on its remaining performance under the contracts with, and actions taken by, MHPSA. The amounts DBT may recover for current and potential future claims against MHPSA are not currently known given (i) the extent of current and potential future claims by MHPSA against DBT (see below for further discussion) and (ii) the unpredictable nature of any dispute resolution processes that may occur in connection with these current and potential future claims. No revenue has been recorded in the accompanying consolidated financial statements with respect to current or potential future claims against MHPSA.

Claims by Prime Contractors - On February 26, 2019, DBT received notification of an interim claim consisting of both direct and consequential damages from MHPSA alleging, among other things, that DBT (i) provided defective product and (ii) failed to meet certain project milestones. We believe the notification is unsubstantiated and the vast majority of the claimed damages are prohibited under the relevant contracts. Therefore, we believe any loss for the majority of these claimed damages is remote. For the remainder of the claims, which largely appear to be direct in nature (approximately South African Rand 948.0 or $67.6), DBT has numerous defenses and, thus, we do not believe that DBT has a probable loss associated with these claims. As such, no loss has been recorded in the accompanying consolidated financial statements with respect to these claims. Although it is reasonably possible that some loss may be incurred in connection with these claims, we currently are unable to estimate the potential loss or range of potential loss associated with these claims due to the (i) lack of support provided by MPHSA for these claims; (ii) complexity of contractual relationships between the end customer, MHPSA, and DBT; (iii) legal interpretation of the contract provisions and application of South African common law to the contracts; and (iv) unpredictable nature of any dispute resolution processes that may occur in connection with these claims.

In April and July 2019, DBT received notifications of intent to claim liquidated damages totaling South African Rand 407.2 (or $29.0) from MHPSA alleging that DBT failed to meet certain project milestones related to the construction of the filters for both the Kusile and Medupi projects. DBT has numerous defenses against these claims and, thus, we do not believe that DBT has a probable loss associated with these claims. As such, no loss has been recorded in the accompanying consolidated financial statements with respect to these claims. Although it is reasonably possible that some loss may be incurred in connection with these claims, we currently are unable to estimate the potential loss or range of potential loss.

In favor of MHPSA, we have issued bonds totaling $65.1 (including $23.3 with more stringent payment terms). We believe a portion of these bonds should be reduced based on project milestones achieved by DBT. In the event that MHPSA were to receive payment on a portion, or all, of these bonds, we would be required to reimburse the bank. In addition to these bonds, SPX Corporation has guaranteed DBT’s performance on these projects to the prime contractors.

On June 28, 2019, DBT reached an agreement with Alstom/GE, the other prime contractor on the projects, to, among other things, settle all material outstanding claims between the parties (other than certain pass-through claims relating to third parties), including a liquidated damages claim made by Alstom/GE. In connection with the agreement, we reduced revenues (and operating income) by $6.0 during the second quarter of 2019.

Claims by Subcontractor - On October 30, 2018, a non-governmental business adjudicator in South Africa provided a decision on certain claims made against DBT by one of its subcontractors. As part of its decision, the adjudicator concluded that the subcontractor was entitled to payment of South African Rand 256.0 (or $18.2). We believed that the decision was invalid on numerous bases and, thus, we did not record a loss in our accompanying consolidated financial statements as a result of the adjudicator’s decision. The matter was referred to an arbitration tribunal and, on January 16, 2020, the arbitration tribunal ruled that the subcontractor was only entitled to a payment of South African Rand 19.4 (or $1.4). The arbitration tribunal’s ruling is binding on both DBT and the subcontractor. We have reflected the liability for such amount within our consolidated balance sheet as of December 31, 2019.

DBT had a Black Economic Empowerment shareholder (the “BEE Partner”) that held a 25.1% noncontrolling interest in DBT. Under the terms of the shareholder agreement between the BEE Partner and SPX Technologies (PTY) LTD (“SPX Technologies”), the BEE Partner had the option to put its ownership interest in DBT to SPX Technologies, the majority shareholder of DBT, at a redemption amount determined in accordance with the terms of the shareholder agreement (the “Put Option”). The BEE Partner notified SPX Technologies of its intention to exercise the Put Option and, on July 6, 2016, an arbitration tribunal declared that the BEE Partner was entitled to South African Rand 287.3 in connection with the exercise of the Put Option, having not considered an amount due from the BEE Partner under a promissory note of South African Rand 30.3 held by SPX Technologies. As a result, beginning in the third quarter of 2016, we reflected the net redemption amount of South African Rand 257.0 (or $17.7 at December 31, 2018) within “Accrued expenses” on our consolidated balance sheet, with the related offset recorded to “Paid-in capital” and “Accumulated other comprehensive income.”

In August 2016, SPX Technologies applied to the High Court of South Africa (the “High Court”) to have the arbitration tribunal’s ruling set aside. On January 22, 2018, the High Court ruled in SPX Technologies' favor and set aside the arbitration tribunal’s ruling. The BEE Partner subsequently applied to the Supreme Court of Appeal of South Africa (the “SCA”) to have the arbitration tribunal’s ruling upheld. On September 6, 2019, the SCA ruled in favor of the BEE Partner. On October 16, 2019, SPX Technologies, DBT, and SPX Corporation executed an agreement with the BEE Partner and its affiliates to settle the Put Option and all other claims between the parties for a total payment of South African Rand 230.0 (or $15.6), which was paid in full on October 21, 2019. The difference between the settlement amount (South African Rand 230.0) and the amount previously recorded of South African Rand 257.0 (see above), or South African Rand 27.0 (or $1.8), along with a tax benefit of $3.8 associated with the total payment of South African Rand 230.0, have been reflected as an adjustment to “Net income attributable to SPX common shareholders” in our calculation of basic and diluted earnings per share for the year ended December 31, 2019, with such adjustment totaling $5.6.

We are subject to other legal matters that arise in the normal course of business. We believe these matters are either without merit or of a kind that should not have a material effect, individually or in the aggregate, on our financial position, results of operations or cash flows; however, we cannot give assurance that these proceedings or claims will not have a material effect on our financial position, results of operations or cash flows.

Our operations and properties are subject to federal, state, local and foreign regulatory requirements relating to environmental protection. It is our policy to comply fully with all applicable requirements. As part of our effort to comply, we have a comprehensive environmental compliance program that includes environmental audits conducted by internal and external independent professionals, as well as regular communications with our operating units regarding environmental compliance requirements and anticipated regulations. Based on current information, we believe that our operations are in substantial compliance with applicable environmental laws and regulations, and we are not aware of any violations that could have a material effect, individually or in the aggregate, on our business, financial condition, and results of operations or cash flows. As of December 31, 2019, we had liabilities for site investigation and/or remediation at 29 sites (28 sites at December 31, 2018) that we own or control. In addition, while we believe that we maintain adequate accruals to cover the costs of site investigation and/or remediation, we cannot provide assurance that new matters, developments, laws and regulations, or stricter interpretations of existing laws and regulations will not materially affect our business or operations in the future.

Our environmental accruals cover anticipated costs, including investigation, remediation, and operation and maintenance of clean-up sites. Our estimates are based primarily on investigations and remediation plans established by independent consultants, regulatory agencies and potentially responsible third parties. Accordingly, our estimates may change based on future developments, including new or changes in existing environmental laws or policies, differences in costs required to complete anticipated actions from estimates provided, future findings of investigation or remediation actions, or alteration to the expected remediation plans. It is our policy to revise an estimate once it becomes probable and the amount of change can be reasonably estimated. We generally do not discount our environmental accruals and do not reduce them by anticipated insurance recoveries. We take into account third-party indemnification from financially viable parties in determining our accruals where there is no dispute regarding the right to indemnification.

In the case of contamination at offsite, third-party disposal sites, as of December 31, 2019, we have been notified that we are potentially responsible and have received other notices of potential liability pursuant to various environmental laws at 14 sites (14 sites at December 31, 2018) at which the liability has not been settled, of which 11 sites have been active in the past few years. These laws may impose liability on certain persons that are considered jointly and severally liable for the costs of investigation and remediation of hazardous substances present at these sites, regardless of fault or legality of the original disposal. These persons include the present or former owners or operators of the site and companies that generated, disposed of or arranged for the disposal of hazardous substances at the site. We are considered a “de minimis” potentially responsible party at most of the sites, and we estimate that our aggregate liability, if any, related to these sites is not material to our consolidated financial statements. We conduct extensive environmental due diligence with respect to potential acquisitions, including environmental site assessments and such further testing as we may deem warranted. If an environmental matter is identified, we estimate the cost and either establish a liability, purchase insurance or obtain an indemnity from a financially sound seller; however, in connection with our acquisitions or dispositions, we may assume or retain significant environmental liabilities, some of which we may be unaware. The potential costs related to these environmental matters and the possible impact on future operations are uncertain due in part to the complexity of government laws and regulations and their interpretations, the varying costs and effectiveness of various clean-up technologies, the uncertain level of insurance or other types of recovery, and the questionable level of our responsibility. We record a liability when it is both probable and the amount can be reasonably estimated.

We are self-insured for certain of our workers’ compensation, automobile, product and general liability, disability and health costs, and we believe that we maintain adequate accruals to cover our retained liability. Our accruals for risk management matters are determined by us, are based on claims filed and estimates of claims incurred but not yet reported, and generally are not discounted. We consider a number of factors, including third-party actuarial valuations, when making these determinations. We maintain third-party stop-loss insurance policies to cover certain liability costs in excess of predetermined retained amounts. This insurance may be insufficient or unavailable (e.g., because of insurer insolvency) to protect us against loss exposure.
