Accounting Policies [Abstract]
Basis of Presentation and Responsibility for Interim Financial Statements	Basis of Presentation and Responsibility for Interim Financial Statements The accompanying unaudited condensed consolidated financial statements of Pentair plc and its subsidiaries (“we,” “us,” “our,” “Pentair,” or the “Company”) have been prepared following the requirements of the U.S. Securities and Exchange Commission (“SEC”) for interim reporting. As permitted under those rules, certain footnotes or other financial information that are normally required by accounting principles generally accepted in the United States of America (“GAAP”) can be condensed or omitted. We are responsible for the unaudited condensed consolidated financial statements included in this document. The financial statements include all normal recurring adjustments that are considered necessary for the fair presentation of our financial position and operating results. As these are condensed financial statements, one should also read our consolidated financial statements and notes thereto, which are included in our Annual Report on Form 10-K for the year ended December 31, 2019. Revenues, expenses, cash flows, assets and liabilities can and do vary during each quarter of the year. Therefore, the results and trends in these interim financial statements may not be indicative of those for a full year. In March 2020, the World Health Organization declared the novel coronavirus 2019 (“COVID-19”) a global pandemic. The COVID-19 pandemic has had and may continue to have an unfavorable impact on certain parts of our business. The broader implications of the COVID-19 pandemic on our business, financial condition and results of operations remain uncertain and will depend on certain developments, including the duration and severity of the COVID-19 pandemic, its impact on our customers and suppliers and the range of governmental and community reactions to the pandemic. We may continue to experience reduced customer demand or constrained supply that could materially adversely impact our business, financial condition, results of operations, liquidity and cash flows in future periods. Our fiscal year ends on December 31. We report our interim quarterly periods on a calendar quarter basis. Adoption of new accounting standards On January 1, 2020, we adopted Accounting Standards Update No. 2016-13 “Financial Instruments-Credit Losses” and the related amendments (the “new standard”). The new standard changes the methodology used to measure credit losses for certain financial instruments and financial assets, including trade receivables. The approach utilizes an expected credit loss model that requires consideration of a broader range of information to estimate expected credit losses over the lifetime of an asset, which may result in earlier recognition of credit losses than under the previous accounting standards. Under the new standard, we record an allowance for credit losses, reducing our trade receivables balance to an amount we estimate is collectible from our customers. The estimates used in determining the allowance for credit losses are based on historical collection experience, including write-offs and recoveries, periodic credit evaluations of our customers’ financial situation, and current circumstances as well as reasonable and supportable forecasts of future economic conditions. The adoption of this new standard did not have a material impact on our consolidated financial statements. The following table summarizes the activity in the allowance for credit losses for the nine months ended September 30, 2020: In millions September 30, Beginning balance $ 10.3 Bad debt expense (0.7) Write-offs, net of recoveries (0.8) Other (1) (0.1) Ending balance $ 8.7 (1) Other amounts are primarily the effects of changes in currency translations and the impact of allowance for credits.

Revenue from Contract with Customer [Abstract]
Revenue	Revenue We disaggregate our revenue from contracts with customers by segment, geographic location and vertical, as we believe these best depict how the nature, amount, timing and uncertainty of our revenue and cash flows are affected by economic factors. Refer to Note 14 for revenue disaggregated by segment. Geographic net sales information, based on geographic destination of the sale, was as follows: Three months ended Nine months ended In millions September 30, September 30, September 30, September 30, U.S. $ 541.2 $ 445.0 $ 1,487.9 $ 1,382.1 Western Europe 92.6 97.8 281.3 309.0 Developing (1) 108.3 119.9 303.2 357.8 Other Developed (2) 56.4 50.9 149.4 153.1 Consolidated net sales $ 798.5 $ 713.6 $ 2,221.8 $ 2,202.0 (1) Developing includes China, Eastern Europe, Latin America, the Middle East and Southeast Asia. (2) Other Developed includes Australia, Canada and Japan. Vertical net sales information was as follows: Three months ended Nine months ended In millions September 30, September 30, September 30, September 30, Residential $ 520.3 $ 395.5 $ 1,375.8 $ 1,230.1 Commercial 126.0 154.3 391.8 475.7 Industrial 152.2 163.8 454.2 496.2 Consolidated net sales $ 798.5 $ 713.6 $ 2,221.8 $ 2,202.0 Performance obligations On September 30, 2020, we had $61.5 million of remaining performance obligations on contracts with an original expected duration of one year or more. We expect to recognize the majority of our remaining performance obligations on these contracts within the next 12 to 18 months. Contract assets and liabilities Contract assets and liabilities consisted of the following: In millions September 30, December 31, $ Change % Change Contract assets $ 55.6 $ 41.0 $ 14.6 35.6 % Contract liabilities 29.1 32.6 (3.5) (10.7) % Net contract assets $ 26.5 $ 8.4 $ 18.1 215.5 % The $18.1 million increase in net contract assets from December 31, 2019 to September 30, 2020 was primarily the result of timing of milestone payments and impact of foreign currency fluctuations. Approximately 80% of our contract liabilities at December 31, 2019 were recognized in revenue in the first nine months of 2020. There were no impairment losses recognized on our contract assets for the three or nine months ended September 30, 2020.

Discontinued Operations and Disposal Groups [Abstract]
Acquisitions	Acquisitions In February 2019, as part of Consumer Solutions, we completed the acquisitions of Aquion, Inc. (“Aquion”) and Pelican Water Systems (“Pelican”) for $163.4 million and $121.1 million, respectively, in cash, net of cash acquired and final working capital true-ups. For Aquion, the excess of purchase price over tangible net assets and identified intangible assets acquired has been allocated to goodwill in the amount of $101.9 million, $4.6 million of which is expected to be deductible for income tax purposes. Identifiable intangible assets acquired as part of the Aquion acquisition include $15.7 million of indefinite-lived trade name intangible assets and $78.8 million of definite-lived customer relationships with an estimated useful life of 15 years. For Pelican, the excess purchase price over tangible net assets acquired has been allocated to goodwill in the amount of $118.0 million, $7.6 million of which is expected to be deductible for income tax purposes. During the first nine months of 2020, our Consumer Solutions reporting segment completed acquisitions with purchase prices totaling $28.5 million in cash, net of cash acquired. The pro forma impact of these acquisitions is not material.

Share-based Payment Arrangement [Abstract]
Share Plans	Share Plans In May 2020, the Pentair plc 2020 Share and Incentive Plan (“2020 Share Plan”) was approved during the Annual General Meeting of Shareholders. The Pentair plc 2012 Stock and Incentive Plan (“2012 Stock Plan”) terminated upon the approval of the 2020 Share Plan, although awards outstanding under the 2012 Stock Plan continue in effect. Beginning May 5, 2020, all share-based compensation grants were made under the 2020 Share Plan. The 2020 Share Plan authorizes the issuance of 3.3 million of our ordinary shares, plus the number of shares reserved under the 2012 Stock Plan that were not the subject of outstanding awards as of the date the 2020 Share Plan became effective, which was 2.5 million shares, plus certain shares that would become available under the 2012 Stock Plan if it had remained in effect. The shares may be issued as new shares or from shares held in treasury. Our practice is to settle equity-based awards by issuing new shares. The 2020 Share Plan terminates on the date all shares reserved for issuance have been issued. The 2020 Share Plan allows for the granting to our employees, consultants and directors of stock options, stock appreciation rights, performance share units, restricted shares, restricted stock units, deferred stock rights, incentive awards, dividend equivalent units and other equity-based awards. The 2020 Share Plan is administered by our compensation committee (the “Committee”), which is made up of independent members of our Board of Directors. Employees eligible to receive awards under the 2020 Share Plan are managerial, administrative or professional employees. The Committee has the authority to select the recipients of awards, determine the type and size of awards, establish certain terms and conditions of award grants and take certain other actions as permitted under the 2020 Share Plan. The 2020 Share Plan prohibits the Committee from re-pricing awards or canceling and reissuing awards at lower prices.

The total number of awards issued was approximately 0.8 million, of which 0.3 million were restricted stock units (“RSUs”), 0.4 million were stock options and 0.1 million were performance share units (“PSUs”). The weighted-average grant date fair value of the RSUs, stock options and PSUs issued was $42.77, $9.58, and $45.40, respectively. We estimated the fair value of each stock option award issued in the annual share-based compensation grant using a Black-Scholes option pricing model, modified for dividends and using the following assumptions: 2020 Risk-free interest rate 1.61 % Expected dividend yield 1.80 % Expected share price volatility 24.10 % Expected term (years) 6.8 These estimates require us to make assumptions based on historical results, observance of trends in our share price, changes in option exercise behavior, future expectations and other relevant factors. If other assumptions had been used, share-based compensation expense, as calculated and recorded under the accounting guidance, could have been affected. We based the expected life assumption on historical experience as well as the terms and vesting periods of the options granted. For purposes of determining expected share price volatility, we considered a rolling average of historical volatility measured over a period approximately equal to the expected option term. The risk-free interest rate for periods that coincide with the expected life of the options is based on the United States (“U.S”). Treasury Department yield curve in effect at the time of grant.

In April 2018, Pentair, Pentair Investments Switzerland GmbH (“PISG”), Pentair Finance S.à r.l (“PFSA“) and Pentair, Inc. entered into a credit agreement, providing for an $800.0 million senior unsecured revolving credit facility with a term of five years (the “Senior Credit Facility”), with Pentair and PISG as guarantors and PFSA and Pentair, Inc. as borrowers. In June 2020, Pentair assumed the PISG guarantee. The Senior Credit Facility has a maturity date of April 25, 2023. Borrowings under the Senior Credit Facility bear interest at a rate equal to an adjusted base rate or the London Interbank Offered Rate, plus, in each case, an applicable margin. The applicable margin is based on, at PFSA’s election, Pentair’s leverage level or PFSA’s public credit rating. In May 2019, PFSA executed an increase of the Senior Credit Facility by $100.0 million for a total commitment up to $900.0 million in the aggregate. In December 2019, the Senior Credit Facility was amended to provide for the extension of term loans in an aggregate amount of $200.0 million (the “Term Loans”). The Term Loans are in addition to the Senior Credit Facility commitment. In addition, PFSA has the option to further increase the Senior Credit Facility in an aggregate amount of up to $300.0 million, through a combination of increases to the total commitment amount of the Senior Credit Facility and/or one or more tranches of term loans in addition to the Term Loans, subject to customary conditions, including the commitment of the participating lenders. PFSA is authorized to sell short-term commercial paper notes to the extent availability exists under the Senior Credit Facility. PFSA uses the Senior Credit Facility as back-up liquidity to support 100% of commercial paper outstanding. PFSA had no commercial paper outstanding as of September 30, 2020 and $117.8 million as of December 31, 2019, all of which was classified as long-term debt as we have the intent and the ability to refinance such obligations on a long-term basis under the Senior Credit Facility. In March 2020, the commercial paper market began to experience high levels of volatility due to uncertainty related to the COVID-19 pandemic. The volatility impacted both market access to and pricing of commercial paper. As a cost mitigation action, we withdrew our credit ratings to access the commercial paper market in the second quarter of 2020 and continued to use the revolving credit facility, along with cash generated from operations, to fund our general operations. As of September 30, 2020, total availability under the Senior Credit Facility was $897.8 million. Our debt agreements contain various financial covenants, but the most restrictive covenants are contained in the Senior Credit Facility. The Senior Credit Facility contains covenants requiring us not to permit (i) the ratio of our consolidated debt (net of our consolidated unrestricted cash in excess of $5.0 million but not to exceed $250.0 million) to our consolidated net income (excluding, among other things, non-cash gains and losses) before interest, taxes, depreciation, amortization and non-cash share-based compensation expense (“EBITDA”) on the last day of any period of four consecutive fiscal quarters to exceed 3.75 to 1.00 (the “Leverage Ratio”) and (ii) the ratio of our EBITDA to our consolidated interest expense, for the same period to be less than 3.00 to 1.00 as of the end of each fiscal quarter. For purposes of the Leverage Ratio, the Senior Credit Facility provides for the calculation of EBITDA giving pro forma effect to certain acquisitions, divestitures and liquidations during the period to which such calculation relates. In addition to the Senior Credit Facility, we have various other credit facilities with an aggregate availability of $21.1 million, of which there were no outstanding borrowings at September 30, 2020. Borrowings under these credit facilities bear interest at variable rates. We have $103.8 million aggregate principal amount of fixed rate senior notes maturing in the next twelve months. We classified this debt as long-term as of September 30, 2020 as we have the intent and ability to refinance such obligation on a long-term basis under the Senior Credit Facility. Debt outstanding, excluding unamortized issuance costs and discounts, at September 30, 2020 matures on a calendar year basis as follows: Q4 In millions 2020 2021 2022 2023 2024 2025 Thereafter Total Contractual debt obligation maturities $ — $ 103.8 $ 88.3 $ 202.2 $ — $ 19.3 $ 400.0 $ 813.6

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives and Financial Instruments	Derivatives and Financial Instruments Derivative financial instruments We are exposed to market risk related to changes in foreign currency exchange rates. To manage the volatility related to this exposure, we periodically enter into a variety of derivative financial instruments. Our objective is to reduce, where it is deemed appropriate to do so, fluctuations in earnings and cash flows associated with changes in foreign currency exchange rates. The derivative contracts contain credit risk to the extent that our bank counterparties may be unable to meet the terms of the agreements. The amount of such credit risk is generally limited to the unrealized gains, if any, in such contracts. Such risk is minimized by limiting those counterparties to major financial institutions of high credit quality. Foreign currency contracts We conduct business in various locations throughout the world and are subject to market risk due to changes in the value of foreign currencies in relation to our reporting currency, the U.S. dollar. We manage our economic and transaction exposure to certain market-based risks through the use of foreign currency derivative financial instruments. Our objective in holding these derivatives is to reduce the volatility of net earnings and cash flows associated with changes in foreign currency exchange rates. The majority of our foreign currency contracts have an original maturity date of less than one year. At September 30, 2020 and December 31, 2019, we had outstanding foreign currency derivative contracts with gross notional U.S. dollar equivalent amounts of $19.5 million and $17.0 million, respectively. The impact of these contracts on the Condensed Consolidated Statements of Operations and Comprehensive Income was not material for any period presented. Cross Currency Swaps At September 30, 2020 and December 31, 2019, we had outstanding cross currency swap agreements with a combined notional amount of $816.6 million and $770.0 million, respectively. The agreements are accounted for as either cash flow hedges, to hedge foreign currency fluctuations on certain intercompany debt, or as net investment hedges to manage our exposure to fluctuations in the Euro-U.S. Dollar exchange rate. We had deferred foreign currency losses of $4.0 million and $1.8 million at September 30, 2020 and December 31, 2019, respectively, in Accumulated other comprehensive loss associated with our cross currency swap activity. Fair value measurements Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Assets and liabilities measured at fair value are classified using the following hierarchy, which is based upon the transparency of inputs to the valuation as of the measurement date: Level 1: Valuation is based on observable inputs such as quoted market prices (unadjusted) for identical assets or liabilities in active markets. Level 2: Valuation is based on inputs such as quoted market prices for similar assets or liabilities in active markets or other inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument. Level 3: Valuation is based upon other unobservable inputs that are significant to the fair value measurement. In making fair value measurements, observable market data must be used when available. When inputs used to measure fair value fall within different levels of the hierarchy, the level within which the fair value measurement is categorized is based on the lowest level input that is significant to the fair value measurement. Fair value of financial instruments The following methods were used to estimate the fair values of each class of financial instruments: • short-term financial instruments (cash and cash equivalents, accounts and notes receivable, accounts and notes payable and variable-rate debt) — recorded amount approximates fair value because of the short maturity period; • long-term fixed-rate debt, including current maturities — fair value is based on market quotes available for issuance of debt with similar terms, which are inputs that are classified as Level 2 in the valuation hierarchy defined by the accounting guidance; • foreign currency contract agreements — fair values are determined through the use of models that consider various assumptions, including time value, yield curves, as well as other relevant economic measures, which are inputs that are classified as Level 2 in the valuation hierarchy defined by the accounting guidance; and • deferred compensation plan assets (mutual funds, common/collective trusts and cash equivalents for payment of certain non-qualified benefits for retired, terminated and active employees) — fair value of mutual funds and cash equivalents are based on quoted market prices in active markets that are classified as Level 1 in the valuation hierarchy defined by the accounting guidance; fair value of common/collective trusts are valued at net asset value (“NAV”), which is based on the fair value of the underlying securities owned by the fund and divided by the number of shares outstanding. The recorded amounts and estimated fair values of total debt, excluding unamortized issuance costs and discounts, were as follows: September 30, December 31, In millions Recorded Fair Recorded Fair Variable rate debt $ 202.2 $ 202.2 $ 353.6 $ 353.6 Fixed rate debt 611.4 674.5 685.4 732.2 Total debt $ 813.6 $ 876.7 $ 1,039.0 $ 1,085.8 Financial assets and liabilities measured at fair value on a recurring and nonrecurring basis were as follows: September 30, 2020 In millions Level 1 Level 2 Level 3 NAV Total Recurring fair value measurements Foreign currency contract assets $ — $ 0.1 $ — $ — $ 0.1 Foreign currency contract liabilities — (27.8) — — (27.8) Deferred compensation plan assets 10.0 — — 9.8 19.8 Total recurring fair value measurements $ 10.0 $ (27.7) $ — $ 9.8 $ (7.9) December 31, 2019 In millions Level 1 Level 2 Level 3 NAV Total Recurring fair value measurements Foreign currency contract assets $ — $ 0.1 $ — $ — $ 0.1 Foreign currency contract liabilities — (11.6) — — (11.6) Deferred compensation plan assets 12.5 — — 8.8 21.3 Total recurring fair value measurements $ 12.5 $ (11.5) $ — $ 8.8 $ 9.8 Nonrecurring fair value measurements (1) (1) During the year ended December 31, 2019, we recorded impairment charges for cost method investments in the amount of $21.2 million, of which $18.2 million was recorded in the nine months ended September 30, 2019. A valuation method using unobservable inputs was utilized to determine the fair value. We wrote the balance of the cost method investments to zero.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes We manage our affairs so that we are centrally managed and controlled in the United Kingdom (“U.K.”) and therefore have our tax residency in the U.K. The provision for income taxes consists of provisions for the U.K. and international income taxes. We operate in an international environment with operations in various locations outside the U.K. Accordingly, the consolidated income tax rate is a composite rate reflecting the earnings in the various locations and the applicable rates. The effective income tax rate for the nine months ended September 30, 2020 was 19.9%, compared to 14.2% for the nine months ended September 30, 2019. We continue to actively pursue initiatives to reduce our effective tax rate. The tax rate in any quarter can be affected positively or negatively by adjustments that are required to be reported in the specific quarter of resolution. On March 27, 2020, the U.S. enacted the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) in response to the COVID-19 pandemic. The CARES Act contains numerous income tax provisions, such as relaxing limitations on the deductibility of interest and the ability to carryback net operating losses arising in taxable years from 2018 through 2020. The CARES Act provides positive cash benefits of approximately $28.7 million, offset by an increase to our 2020 annual effective tax rate of approximately 1.0% and $5.1 million in discrete tax items recorded in the first nine months of 2020 mainly attributable to base erosion and anti-abuse tax related to 2019. In April 2020, the Internal Revenue Service released final regulations as part of the Tax Cuts and Jobs Act of 2017 that place limitations on the deductibility of certain interest expense for U.S. tax purposes. These regulations resulted in discrete tax expense of approximately $14.1 million in the second quarter of 2020, as well as an increase to our 2020 annual effective tax rate of approximately 0.5%. The liability for uncertain tax positions was $46.8 million and $47.4 million at September 30, 2020 and December 31, 2019, respectively. We record penalties and interest related to unrecognized tax benefits in Provision for income taxes and Net interest expense , respectively, on the Condensed Consolidated Statements of Operations and Comprehensive Income, which is consistent with our past practices.

For the nine months ended September 30, 2019, we contributed $11.1 million to the Salaried Plan as part of the process to settle our obligations. As a result of these actions, a non-cash pre-tax settlement gain of $11.8 million was recorded for the nine months ended September 30, 2019.

The authorization expires on May 31, 2021. During the nine months ended September 30, 2020, we repurchased 3.0 million of our shares for $115.2 million. As of September 30, 2020, we had $134.7 million available for share repurchases under this authorization. In March 2020, to enhance our liquidity position in response to the COVID-19 pandemic, we elected to temporarily suspend share repurchases under our existing share repurchase program. The temporary suspension of share repurchases has been lifted. The existing program remains authorized by the Board of Directors, and we may resume share repurchases in the future at any time, depending upon market conditions, our capital needs and other factors.

Segment Reporting [Abstract]
Segment Information	Segment Information Effective January 1, 2020, we reorganized our business segments to better support our organization with our strategies and to better align with our customer base, resulting in a change to our reporting segments. All prior period amounts related to the segment change have been retrospectively reclassified to conform to the new presentation. As part of this reorganization, the legacy Aquatic Systems, Flow Technologies, and Filtration Solutions segments were realigned into two reportable business segments: • Consumer Solutions — This segment designs, manufactures and sells energy-efficient residential and commercial pool equipment and accessories, and commercial and residential water treatment products and systems. Residential and commercial pool equipment and accessories include pumps, filters, heaters, lights, automatic controls, automatic cleaners, maintenance equipment and pool accessories. Water treatment products and systems include pressure tanks, control valves, activated carbon products, conventional filtration products, and point-of-entry and point-of-use systems. Applications for our pool business’s products include residential and commercial pool maintenance, repair, renovation, service and construction. Our water treatment products and systems are used in residential whole home water filtration, drinking water filtration and water softening solutions in addition to commercial total water management and filtration in foodservice operations. The primary focus of this segment is business-to-consumer. • Industrial & Flow Technologies — This segment manufactures and sells a variety of fluid treatment and pump products and systems, including pressure vessels, gas recovery solutions, membrane bioreactors, wastewater reuse systems and advanced membrane filtration, separation systems, water disposal pumps, water supply pumps, fluid transfer pumps, turbine pumps, solid handling pumps, and agricultural spray nozzles, while serving the global residential, commercial and industrial markets. These products and systems are used in a range of applications, fluid delivery, ion exchange, desalination, food and beverage, separation technologies for the oil and gas industry, residential and municipal wells, water treatment, wastewater solids handling, pressure boosting, circulation and transfer, fire suppression, flood control, agricultural irrigation and crop spray. The primary focus of this segment is business-to-business. We evaluate performance based on net sales and segment income (loss) and use a variety of ratios to measure performance of our reporting segments.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Warranties and guarantees In connection with our disposition of businesses, product lines and assets, we often provide representations, warranties and indemnities to cover purchasers for various potential liabilities relating to the sold businesses, product lines and assets, such as unknown damages or liabilities relating to the assets and pre-closing tax, product liability, warranty, environmental, or other obligations. The subject matter, amounts and duration of any such indemnification obligations vary for each type of liability indemnified and may vary widely from transaction to transaction. Generally, the maximum obligations under such indemnifications are not explicitly stated and as a result, the overall amount of these obligations cannot be reasonably estimated due to their inchoate and unknown nature. Historically, we have not made significant payments for these indemnifications. We believe that if we were to incur a loss in any of these matters, the loss would not have a material adverse effect on our financial position, results of operations or cash flows. We recognize, at the inception of a guarantee, a liability for the fair value of the obligation undertaken in issuing the guarantee. We provide service and warranty policies on our products. Liability under service and warranty policies is based upon a review of historical warranty and service claim experience. Adjustments are made to accruals as claim data and historical experience warrant. The changes in the carrying amount of service and product warranties of continuing operations for the nine months ended September 30, 2020 were as follows: In millions September 30, Beginning balance $ 32.1 Service and product warranty provision 42.2 Payments (38.3) Foreign currency translation 0.2 Ending balance $ 36.2 Stand-by letters of credit, bank guarantees and bonds In certain situations, Tyco International Ltd., Pentair Ltd.’s former parent company (“Tyco”), guaranteed performance by the flow control business of Pentair Ltd. (“Flow Control”) to third parties or provided financial guarantees for financial commitments of Flow Control. In situations where Flow Control and Tyco were unable to obtain a release from these guarantees in connection with the spin-off of Flow Control from Tyco, we will indemnify Tyco for any losses it suffers as a result of such guarantees. In the ordinary course of business, we are required to commit to bonds, letters of credit and bank guarantees that require payments to our customers for any non-performance. The outstanding face value of these instruments fluctuates with the value of our projects in process and in our backlog. In addition, we issue financial stand-by letters of credit primarily to secure our performance to third parties under self-insurance programs. As of September 30, 2020 and December 31, 2019, the outstanding value of bonds, letters of credit and bank guarantees totaled $97.3 million and $91.3 million, respectively.

Accounting Policies [Abstract]
Adoption of new accounting standards	Adoption of new accounting standards On January 1, 2020, we adopted Accounting Standards Update No. 2016-13 “Financial Instruments-Credit Losses” and the related amendments (the “new standard”). The new standard changes the methodology used to measure credit losses for certain financial instruments and financial assets, including trade receivables. The approach utilizes an expected credit loss model that requires consideration of a broader range of information to estimate expected credit losses over the lifetime of an asset, which may result in earlier recognition of credit losses than under the previous accounting standards. Under the new standard, we record an allowance for credit losses, reducing our trade receivables balance to an amount we estimate is collectible from our customers. The estimates used in determining the allowance for credit losses are based on historical collection experience, including write-offs and recoveries, periodic credit evaluations of our customers’ financial situation, and current circumstances as well as reasonable and supportable forecasts of future economic conditions. The adoption of this new standard did not have a material impact on our consolidated financial statements. The following table summarizes the activity in the allowance for credit losses for the nine months ended September 30, 2020: In millions September 30, Beginning balance $ 10.3 Bad debt expense (0.7) Write-offs, net of recoveries (0.8) Other (1) (0.1) Ending balance $ 8.7 (1) Other amounts are primarily the effects of changes in currency translations and the impact of allowance for credits.
