General [Abstract]
General	Note 1: General The accompanying condensed consolidated financial statements of Modine Manufacturing Company (“Modine” or the “Company”) were prepared in conformity with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes necessary for a comprehensive presentation of financial position, results of operations and cash flows required by GAAP for complete financial statements. The financial statements include all normal recurring adjustments that are, in the opinion of management, necessary for a fair statement of results for the interim periods. Results for the first six months of fiscal 2021 are not necessarily indicative of the results to be expected for the full year. These financial statements should be read in conjunction with the consolidated financial statements and related notes in Modine’s Annual Report on Form 10-K for the year ended March 31, 2020. COVID-19 In March 2020, the World Health Organization declared the outbreak of the novel coronavirus, COVID-19, a pandemic. See Note 17 for additional information regarding the risks and uncertainties to our business resulting from this global pandemic. Chief Executive Officer (“CEO”) Transition In August 2020, Thomas A. Burke stepped down from his position as President and CEO. The Board of Directors launched a search for a new CEO and named Michael B. Lucareli, the Company’s Vice President, Finance and Chief Financial Officer, as Interim President and CEO. As a result of Mr. Burke's departure and in connection with the search for his successor, the Company recorded costs totaling $ million during the second quarter of fiscal 2021. These costs, which were recorded as selling, general and administrative (“SG&A”) expenses at Corporate, primarily consisted of severance and benefit-related expenses based upon the terms of Mr. Burke's transition and separation agreement and costs directly associated with the CEO search, partially offset by the impact of Mr. Burke's forfeited stock-based compensation awards. Sale of Nikkei Heat Exchanger Company, Ltd. (“NEX”) During the second quarter of fiscal 2020, the Company completed the sale of its ownership interest in NEX for a selling price of $ million. Prior to the sale, the Company accounted for its investment in this non-consolidated affiliate using the equity method. As a result of this sale, the Company recorded a gain of $ million, which included the write-off of accumulated foreign currency translation gains of $ million, within other income and expense on the consolidated statements of operations. New Accounting Guidance In June 2016, the Financial Accounting Standards Board issued new guidance related to the accounting for credit losses for certain financial assets, including trade accounts receivable and contract assets. The new guidance modifies the credit loss model to measure and recognize credit losses based upon expected losses rather than incurred losses. The Company adopted this guidance as of April 1, 2020. The adoption did not have a material impact on the Company’s consolidated balance sheets, statements of operations or statements of cash flows.

The $7.1 million decrease in contract assets during the first six months of fiscal 2021 primarily resulted from a decrease in contract assets for revenue recognized over time. Contract liabilities, included within other current liabilities in the consolidated balance sheets, consist of payments received in advance of satisfying performance obligations under customer contracts, including contracts for customer-owned tooling. The $2.8 million increase in contract liabilities during the first six months of fiscal 2021 was primarily related to customer contracts for which payment was received in advance of the Company’s satisfaction of performance obligations.

Fair Value Measurements

Fair Value Measurements [Abstract]
Fair Value Measurements	Note 3: Fair Value Measurements Fair value is defined as the price that would be received for an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants. Fair value measurements are classified under the following hierarchy: ● Level 1 – Quoted prices for identical instruments in active markets. ● Level 2 – Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs are observable in active markets. ● Level 3 – Model-derived valuations in which one or more significant inputs are not observable. When available, the Company uses quoted market prices to determine fair value and classifies such measurements as Level 1. In some cases, where market prices are not available, the Company uses observable market-based inputs to calculate fair value, in which case the measurements are classified as Level 2. If quoted or observable market prices are not available, the Company determines fair value based upon valuation models that use, where possible, market-based data such as interest rates, yield curves or currency rates. These measurements are classified as Level 3. The carrying values of cash, cash equivalents, restricted cash, short-term investments, trade accounts receivable, accounts payable, and short-term debt approximate fair value due to the short-term nature of these instruments. The Company holds investments in deferred compensation trusts to fund obligations under certain non-qualified deferred compensation plans. The Company records the fair value of these investments within other noncurrent assets on its consolidated balance sheets. The Company classifies money market investments held by the trusts within Level 2 of the valuation hierarchy. The Company classifies all other investments held by the trusts within Level 1 of the valuation hierarchy, as it uses quoted market prices to determine the investments’ fair value. The Company’s deferred compensation obligations, which are recorded as other noncurrent liabilities, are recorded at the fair values of the investments held by the trust. The fair values of the investments and obligations for the Company’s deferred compensation plans each totaled and as of September 30 and March respectively. The fair value of the Company’s long-term debt is disclosed in Note

The Company calculates compensation expense based upon the fair value of the instruments at the time of grant and subsequently recognizes expense ratably over the respective vesting periods of the stock-based awards. The Company recognized stock-based compensation expense of $1.4 million and $2.7 million for the three months ended September 30,2020 and 2019, respectively. The Company recognized stock-based compensation expense of $ million and $ million for the six months ended , respectively. As of September 30, 2020, unrecognized compensation expense related to non-vested stock-based compensation awards, which will be amortized over the remaining service periods, was as follows: Unrecognized Compensation Expense Weighted-Average Remaining Service Period in Years Stock options $ 1.2 2.0 Restricted stock awards 3.9 2.7 Performance stock awards 0.4 1.5 Total $ 5.5 2.5 In October 2020, the Company granted stock-based awards to officers and other executives under the LTIP. The Company granted 0.4 million each of restricted stock awards and stock options, with fair values of $6.62 and $3.32 per award, respectively. In lieu of performance-based stock awards, the Company granted performance cash awards to the LTIP participants. The performance metrics for the cash awards are based upon a target three-year average cash flow return on invested capital and a target three-year average revenue growth at the end of the three-year performance period ending March 31, 2023. These performance metrics are the same as those contained within the fiscal 2020 and 2019 performance-based stock awards.

Restructuring Activities [Abstract]
Restructuring Activities	Note 6: Restructuring Activities The Company is currently transferring production from its manufacturing facility in Zhongshan, China to another CIS segment manufacturing facility in China, which it expects to complete in the third quarter of fiscal 2021. As a result of the plant consolidation activities in China, the Company recorded $1.3 million and $3.0 million of severance expenses during the three and six months ended September 30, 2020, respectively. In addition, the Company is in the process of transferring product lines to its CIS manufacturing facility in Mexico. During the first quarter of fiscal 2021, the Company implemented targeted headcount reductions, the most significant of which were in North America in the HDE and CIS segments. The headcount reductions were in response to lower market demand and support the Company’s objective of reducing operational and SG&A cost structures. The Company’s restructuring actions during the first six months of fiscal 2020 consisted primarily of targeted headcount reductions and plant consolidation activities. The fiscal 2020 headcount reductions were primarily in Europe within the Automotive segment and in the Americas within the HDE segment. Restructuring and repositioning expenses were as follows: Three months ended September 30, Six months ended September 30, 2020 2019 2020 2019 Employee severance and related benefits $ 1.3 $ 1.8 $ 5.7 $ 3.3 Other restructuring and repositioning expenses 0.2 0.5 0.4 0.8 Total $ 1.5 $ 2.3 $ 6.1 $ 4.1 Other restructuring and repositioning expenses primarily consist of equipment transfers and plant consolidation costs.

Income Taxes [Abstract]
Income Taxes	Note : Income Taxes The Company’s effective tax rate for the months ended September 30, 2020 and was and , respectively. The Company’s effective tax rate for the six months ended September 30, 2020 and was percent and percent, respectively. The effective tax rates for the fiscal periods were negatively impacted by an income tax charge related to a valuation allowance on deferred tax assets in the U.S., as further described below, and favorably impacted by the global intangible low taxed income (“GILTI”) provision of the Tax Cuts and Jobs Act, as finalized regulations were enacted in the quarter. In the fiscal periods, the effective tax rates were favorably impacted by the release of an unrecognized tax benefit. During the quarter of fiscal the Company recorded an income tax charge of to increase its valuation allowance on certain U.S. deferred tax assets after determining it was more likely than not the deferred tax assets would not be realized based upon finalized foreign tax credit regulations enacted during the quarter. As of September valuation allowances against deferred tax assets in certain foreign jurisdictions and the U.S. totaled and , respectively. The Company will maintain the valuation allowances in each applicable tax jurisdiction until it determines it is more likely than not the deferred tax assets will be realized, thereby eliminating the need for a valuation allowance. As further discussed in Note the COVID- pandemic has resulted in risks and uncertainties to our business. Future events or circumstances, such as lower taxable income or unfavorable changes in the financial outlook of the Company’s operations in the U.S. and certain foreign jurisdictions, could necessitate the establishment of further valuation allowances, which could have a material adverse effect on the Company’s results of operations and financial condition. Accounting policies for interim reporting require the Company to adjust its effective tax rate each quarter to be consistent with its estimated annual effective tax rate. Under this methodology, the Company applies its estimated annual income tax rate to its year-to-date ordinary earnings to derive its income tax provision each quarter. The Company records the tax impacts of certain significant, unusual or infrequently occurring items in the period in which they occur. The Company excluded the impact of its operations in certain foreign locations from the overall effective tax rate methodology and recorded them discretely based upon year-to-date results because the Company anticipates net operating losses for the full fiscal year in these jurisdictions. The Company does not anticipate a significant change in unrecognized tax benefits during the remainder of fiscal

In addition, the calculation for both the three and six months ended September 30, 2020 excluded 0.4 million restricted stock awards because they were anti-dilutive. For the three and six months ended September 30, 2019, the calculation of diluted earnings per share excluded 0.9 million and 0.8 million stock options, respectively, because they were anti-dilutive. In addition, the calculation for both the three and six months ended September 30, 2019 excluded 0.5 million restricted stock awards because they were anti-dilutive. For the three months ended September 30, 2019, the total number of potentially-dilutive securities was 0.3 million. However, these securities were not included in the computation of diluted net loss per share since to do so would have decreased the loss per share.

At September 30, 2020, the weighted-average interest rates for revolving credit facility borrowings and the term loans were both 2.8 percent. At September 30, 2020, the Company’s revolving credit facility borrowings totaled $52.9 million and domestic letters of credit totaled $5.7 million, resulting in available borrowings under the revolving credit facility of $191.4 million. The Company also maintains credit agreements for its foreign subsidiaries, with outstanding short-term borrowings of $17.1 million and $14.8 million at September 30, 2020 and March 31, 2020, respectively. Provisions in the Company’s credit agreement, Senior Note agreements, and various foreign credit agreements require the Company to maintain compliance with various covenants and include certain cross-default clauses. Under its primary debt agreements in the U.S., the Company has provided liens on substantially all domestic assets. Also, as specified in the credit agreement, the term loans may require prepayments in the event of certain asset sales. In addition, at the time of each incremental borrowing under the revolving credit facility, the Company is required to represent to the lenders that there has been no material adverse effect, as defined in the credit agreement, on its business, property, or results of operations. In May 2020, the Company executed amendments to its primary credit agreements in the U.S. Under the amended agreements, the leverage ratio covenant limit has been temporarily raised. The leverage ratio covenant requires the Company to limit the ratio of its consolidated indebtedness, less a portion of its cash balance, both as defined by the credit agreements, to its consolidated net earnings before interest, taxes, depreciation, amortization, and certain other adjustments (“Adjusted EBITDA”). The leverage ratio covenant limit for the second quarter of fiscal 2021 was 4.75 to 1. The leverage ratio covenant limit for the remainder of fiscal 2021 is 5.25 to 1 and 5.75 to 1 for the third and fourth quarters, respectively. In fiscal 2022, the leverage ratio covenant limit is 4.75 to 1, 3.75 to 1, and 3.50 to 1 for the first, second and third quarters, respectively, and subsequently returns to 3.25 to 1 for the fourth quarter of fiscal 2022. The Company is also subject to an interest expense coverage ratio covenant, which requires the Company to maintain Adjusted EBITDA of at least three times consolidated interest expense. The Company was in compliance with its debt covenants as of September 30, 2020. The Company estimates the fair value of long-term debt using discounted future cash flows at rates offered to the Company for similar debt instruments of comparable maturities. As of September 30, 2020 and March 31, 2020, the carrying value of the Company’s long-term debt approximated fair value, with the exception of the Senior Notes, which had an aggregate fair value of approximately $136.6 million and $131.3 million, respectively. The fair value of the Company’s long-term debt is categorized as Level 2 within the fair value hierarchy. Refer to Note 3 for the definition of a Level 2 fair value measurement.

Risks, Uncertainties, Contingencies and Litigation [Abstract]
Risks, Uncertainties, Contingencies and Litigation	Note 17: Risks, Uncertainties, Contingencies and Litigation COVID-19 In March 2020, the World Health Organization declared the outbreak of the novel coronavirus, COVID-19, a pandemic. The spread of COVID-19 and the resulting work and travel restrictions, including international border closings, have disrupted, and may continue to disrupt, global supply chains and have negatively impacted the global economy. As a result of this pandemic, the Company has experienced significant impacts on its operations. Local government requirements or customer shutdowns caused the Company to suspend production at many of its manufacturing facilities in March and April 2020. All of the temporarily-closed facilities have reopened and have been trending back towards normal production levels. The Company is continuing to focus on protecting the health and wellbeing of its employees and the communities in which it operates, while also ensuring the continuity of its business operations and timely delivery of quality products and services to its customers. T o mitigate the negative impacts of COVID-19, the Company has taken actions, including, but not limited to, production staffing adjustments, furloughs, shortened work weeks, and temporary salary reductions at all levels of the organization. In addition, the Company is focused on reducing operating and administrative expenses. Based upon its current expectations, the Company believes that its sources of liquidity will generate sufficient cash flow to meet its obligations during the next twelve months from the date these financial statements are issued. The Company’s consolidated financial statements reflect estimates and assumptions made by management, including assumptions regarding the future impacts of the COVID- pandemic, that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and reported amounts of revenue and expenses during the reporting periods presented. For example, assets particularly sensitive to assumptions that could be adversely impacted by the COVID- pandemic include goodwill and deferred tax assets. While the Company believes it used appropriate estimates and assumptions to prepare the consolidated financial statements, actual amounts could differ materially and future events or circumstances could have a potential negative effect on the assumptions used. If the Company, its suppliers, or its customers experience further shutdowns or other significant business disruptions associated with the COVID- pandemic, its ability to conduct business in the manner and on the timelines presently planned could be materially and negatively impacted, which could have a material adverse effect on the Company’s business, financial position, results of operations and cash flows. Environmental The Company has recorded environmental investigation and remediation accruals related to soil and groundwater contamination at manufacturing facilities in the U.S., of which the Company currently owns and operates, and at its former manufacturing facility in the Netherlands, along with accruals for lesser environmental matters at certain other facilities in the U.S. These accruals generally relate to facilities where past operations followed practices and procedures that were considered acceptable under then-existing regulations, or where the Company is a successor to the obligations of prior owners, and current laws and regulations require investigative and/or remedial work to ensure sufficient environmental compliance. The accruals for these environmental matters totaled and as of September and March respectively. As additional information becomes available, the Company will re-assess the liabilities related to these matters and revise the estimated accruals, if necessary. Based upon currently available information, the Company believes the ultimate outcome of these matters, individually and in the aggregate, will not have a material adverse effect on its financial position. However, these matters are subject to inherent uncertainties, and unfavorable outcomes could occur, including significant monetary damages. Other Litigation In the normal course of business, the Company and its subsidiaries are named as defendants in various lawsuits and enforcement proceedings by private parties, governmental agencies and/or others in which claims are asserted against Modine. The Company believes that any additional loss in excess of amounts already accrued would not have a material effect on the Company’s consolidated balance sheet, results of operations, and cash flows. In addition, management expects that the liabilities which may ultimately result from such lawsuits or proceedings, if any, would not have a material adverse effect on the Company’s financial position.

Segment Information [Abstract]
Segment Information	Note 19: Segment Information Effective April 1, 2020, the Company began managing its global automotive business separate from the other businesses within the previously-reported Vehicular Thermal Solutions (“VTS”) segment. The Company is managing the automotive business as the Automotive segment as it targets the sale or eventual exit of its underlying automotive business operations. The other businesses of the VTS segment, including the commercial vehicle and off-highway businesses, are being managed as the Heavy Duty Equipment segment. The segment realignment had no impact on the CIS and BHVAC segments or on the Company’s consolidated financial position, results of operations, and cash flows. Segment financial information for fiscal 2020 has been recast to conform to the fiscal 2021 presentation.

Subsequent Event [Abstract]
Subsequent Event	Note 20: Subsequent Event On November 2, 2020, the Company announced that it signed a definitive agreement to sell its liquid-cooled automotive business to Dana Incorporated. The Company expects this transaction to close during the first half of calendar 2021, subject to regulatory approvals and other customary closing conditions. The Company does not expect significant net cash proceeds from this transaction based upon the selling price and adjustments for cash, debt, and working capital, as defined within the definitive agreement. The Company reports financial results of the liquid-cooled automotive business within its Automotive segment. Net sales attributable to the liquid-cooled automotive business were approximately $130.0 million during the first six months of fiscal 2021 and approximately $310.0 million in fiscal 2020. Net assets of this business were approximately $140.0 million as of September 30, 2020. There is goodwill or intangible assets recorded within the liquid-cooled automotive business. In connection with the pending sale, the Company expects to classify the liquid-cooled automotive business (the “disposal group”) as held for sale beginning in the third quarter of fiscal 2021 and plans to report the assets and liabilities of this business as held for sale beginning with its December 31, 2020 consolidated balance sheet. As a result of the disposal group being classified as held for sale, the Company expects to record a non-cash impairment charge of approximately $120.0 million to $130.0 million during the third quarter of fiscal 2021 related to the disposal group’s long-lived assets, which consist of property, plant and equipment. When the transaction is completed, the Company expects to record an additional loss on sale related to other net assets and cumulative foreign currency translation adjustments attributable to the disposal group, net working capital adjustments, and costs to sell. As the Company has not yet finalized its analysis, the impairment charge recorded in the third quarter could differ materially from the Company’s preliminary estimate and, at this time, the Company cannot estimate the loss on sale to be recorded upon completion of this transaction.

Basis of Presentation	The accompanying condensed consolidated financial statements of Modine Manufacturing Company (“Modine” or the “Company”) were prepared in conformity with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes necessary for a comprehensive presentation of financial position, results of operations and cash flows required by GAAP for complete financial statements. The financial statements include all normal recurring adjustments that are, in the opinion of management, necessary for a fair statement of results for the interim periods. Results for the first six months of fiscal 2021 are not necessarily indicative of the results to be expected for the full year. These financial statements should be read in conjunction with the consolidated financial statements and related notes in Modine’s Annual Report on Form 10-K for the year ended March 31, 2020.
New Accounting Guidance	New Accounting Guidance In June 2016, the Financial Accounting Standards Board issued new guidance related to the accounting for credit losses for certain financial assets, including trade accounts receivable and contract assets. The new guidance modifies the credit loss model to measure and recognize credit losses based upon expected losses rather than incurred losses. The Company adopted this guidance as of April 1, 2020. The adoption did not have a material impact on the Company’s consolidated balance sheets, statements of operations or statements of cash flows.
