General [Abstract]
General	Note 1: General The accompanying condensed consolidated financial statements were prepared in conformity with generally accepted accounting principles (“GAAP”) in the United States applied on a basis consistent with those principles used in the preparation of the annual consolidated financial statements of Modine Manufacturing Company (“Modine” or the “Company”) for the fiscal year ended March 31, 2018, except in regard to the new accounting guidance adopted, as described below. 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 three months of fiscal 2019 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, 2018. New Accounting Guidance Revenue Recognition In May 2014, the Financial Accounting Standards Board (“FASB”) issued new guidance that outlines a comprehensive model for entities to use in accounting for revenue arising from contracts with customers. The core principle of the new guidance is that companies are to recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The new guidance also includes a cohesive set of disclosure requirements intended to provide users of financial statements with comprehensive information about revenue arising from contracts with customers. The Company adopted this new guidance for its first quarter of fiscal 2019 using the modified-retrospective transition method. The Company assessed customer contracts and evaluated contractual provisions in light of the new guidance. Through its evaluation process, the Company identified a limited number of customer contracts that provide an enforceable right to payment for customized products, which require revenue recognition prior to the product being shipped to the customer. As a result of its adoption of the new guidance, the Company recorded an increase of $0.7 million to retained earnings as of April 1, 2018, along with related balance sheet reclassifications. The increase to retained earnings reflects $3.0 million of net sales that, had the new guidance been in effect, the Company would have recognized as of March 31, 2018. See Note 2 for additional information regarding revenue recognition. Income Taxes: Intra-Entity Transfers of Assets Other Than Inventory In October 2016, the FASB issued new guidance related to income tax accounting for intercompany asset transfers. This new guidance requires companies to recognize the income tax effects of intercompany asset transfers other than inventory at the transaction date. The income tax effects of these transfers were previously deferred. The Company adopted this new guidance for its first quarter of fiscal 2019 using the modified-retrospective transition method. Upon adoption, the Company recorded a decrease to retained earnings of $8.3 million as of April 1, 2018. Statement of Cash Flows: Restricted Cash In November 2016, the FASB issued new guidance that requires restricted cash to be included with cash and cash equivalents when reconciling the beginning and ending balances presented within the statement of cash flows. The Company adopted this new guidance for its first quarter of fiscal 2019 using the retrospective transition method. As a result, all prior period information has been recast to be comparable to the new presentation requirements. See Note 10 for information regarding the Company’s restricted cash. Leases In February 2016, the FASB issued new comprehensive lease accounting guidance that supersedes existing lease accounting guidance. Upon adoption of this new guidance, the Company will be required to recognize most leases on its balance sheet. This guidance is effective for the Company’s first quarter of fiscal 2020. The Company is currently evaluating the impact this guidance will have on its consolidated financial statements. Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income In February 2018, the FASB issued new guidance related to the accounting for certain stranded income tax effects in accumulated other comprehensive income (loss) resulting from tax reform legislation that was enacted in the U.S. in December 2017. This guidance permits companies to reclassify stranded income tax effects to retained earnings and is effective for the Company’s first quarter of fiscal 2020. The Company is currently evaluating the impact this guidance will have on its consolidated financial statements. The cumulative effects on the Company’s consolidated balance sheet, as of April 1, 2018, resulting from the adoption of new accounting guidance were as follows: Adjustments Due to New Accounting Guidance Balance as of March 31, 2018 Revenue Recognition Intra-entity Transfers of Assets Balance as of April 1, 2018 ASSETS Inventories $ 191.3 $ (2.0 ) $ - $ 189.3 Other current assets 70.1 3.0 (8.3 ) 64.8 Deferred income taxes 96.9 (0.2 ) - 96.7 LIABILITIES AND SHAREHOLDERS' EQUITY Deferred income taxes $ 9.9 $ 0.1 $ - $ 10.0 Retained earnings 394.9 0.7 (8.3 ) 387.3

Revenue Recognition [Abstract]
Revenue Recognition	Note 2: Revenue Recognition Effective April 1, 2018, the Company adopted new revenue recognition accounting guidance using the modified-retrospective transition method and, as a result, recorded a cumulative-effect adjustment to increase retained earnings by $0.7 million. The Company’s condensed consolidated financial statements for the three months ended June 30, 2018 reflect the adoption of this new guidance; however the comparable prior-year period has not been restated. See Note 1 for additional information regarding the adjustments to the Company’s consolidated balance sheet as of April 1, 2018. Significant Accounting Policy The Company generates revenue from selling innovative thermal management products and solutions to diversified global markets and customers. The Company recognizes revenue based upon consideration specified in a contract and as it satisfies performance obligations by transferring control over its products to its customers, which may be at a point in time or over time. The majority of the Company’s revenue is recognized at a point in time, based upon shipment terms. The Company records an allowance for doubtful accounts for estimated uncollectible receivables and accrues for estimated warranty costs at the time of sale. These estimates are based upon historical experience, current business trends, and current economic conditions. The Company accounts for shipping and handling activities as fulfilment costs rather than separate performance obligations, and records shipping and handling costs in cost of sales and related amounts billed to customers in net sales. The Company establishes payment terms with its customers based upon industry and regional practices, which typically do not exceed 90 days. As the Company expects to receive payment from its customers within one year from the time of sale, it disregards the effects of the time value of money in its determination of the transaction price. The Company has not disclosed the value of unsatisfied performance obligations because the original expected performance period is one year or less for the large majority of its customer contracts. Nature of Goods and Services and Significant Judgments The following is a description of the Company’s principal revenue-generating activities: Vehicular Thermal Solutions (“VTS”) The VTS segment principally generates revenue from providing engineered heat transfer systems and components for use in on- and off-highway original equipment. This segment provides powertrain and engine cooling products, including, but not limited to, radiators, charge air coolers, condensers, oil coolers, EGR coolers, and fuel coolers, to original equipment manufacturers (“OEMs”) in the automotive, commercial vehicle, and off-highway markets in the Americas, Europe, and Asia regions. In addition, the VTS segment designs customer-owned tooling for OEMs and also serves Brazil’s automotive and commercial vehicle aftermarkets. While the VTS segment provides customized production and service parts to customers under multi-year programs, these programs typically do not contain contractually-guaranteed volumes to be purchased by the customer. As a result, individual purchase orders typically represent the quantities ordered by the customer. With the exception of a small number of VTS customers, the terms within the customer agreement, purchase order, or customer-owned tooling contract do not provide the Company with an enforceable right to payment for performance completed to date. As a result, the VTS segment recognizes revenue primarily at the time control is transferred to the customer based upon shipping terms, which is generally upon shipment. In regard to VTS customers with contractual cancellation terms that provide an enforceable right to payment for performance completed to date, the Company recognizes revenue over time based upon its estimated progress towards satisfaction of the performance obligations. The VTS segment measures progress by evaluating the production status of ordered products not yet shipped to the customer. For certain customer programs, the Company agrees to provide annual price reductions based upon contract terms. For these scheduled price reductions, the Company evaluates whether the provisions represent a material right to the customer, and if so, defers associated revenue as a result. At times, the Company makes up-front incentive payments to certain customers related to future sales under multi-year programs. The Company capitalizes these incentive payments, which it expects to recover through future sales, and amortizes the assets as a reduction to revenue when the related products are sold to customers. Commercial and Industrial Solutions (“CIS”) The CIS segment principally generates revenue from providing thermal management products, including customized coils and coolers, to the heating, ventilating, air conditioning, and refrigeration (“HVAC&R”) markets in North America, Europe, and Asia. In addition, the segment applies corrosion protection solutions, which are referred to as coatings, to heat-transfer equipment. For the sale of coils and coolers, individual customer purchase orders generally represent the Company’s contract with its customers. With the exception of a small number of customers, the applicable customer contracts do not provide the Company with an enforceable right to payment for performance completed to date. As a result, the CIS segment recognizes revenue for its sale of coils and coolers primarily at the time control is transferred to the customer based upon shipping terms, which is generally upon shipment. For both sales to customers whose contract cancellation terms provide an enforceable right to payment and sales from the coatings businesses, in which the customers control the heat-transfer equipment being enhanced by the coating application, the CIS segment recognizes revenue over time based upon its estimated progress towards satisfaction of the performance obligations. The segment measures progress by evaluating the production status towards completion of ordered products or services not yet shipped to its customers. Building HVAC Systems (“BHVAC”) The BHVAC segment principally generates revenue from providing a variety of heating, ventilating, and air conditioning products, primarily for commercial buildings and related applications in North America and the U.K., as well as mainland Europe and the Middle East. Heating products are manufactured in the U.S. and are generally sold to independent distributors, who in turn market the heating products to end customers. Because these products are sold to many different customers without contractual or practical limitations, the BHVAC segment recognizes revenue at the time control is transferred to the customer based upon shipping terms, which is generally upon shipment. Ventilation and air conditioning products are highly-specified to a customer’s needs; however, the underlying sales contracts do not provide the Company with an enforceable right to payment for performance completed to date. As a result, the BHVAC segment recognizes revenue for these products at the time control is transferred to the customer based upon shipping terms, which is generally upon shipment. Disaggregation of Revenue The table below presents revenue to external customers for each of the Company’s business segments by primary end market, by geographic location and based upon the timing of revenue recognition.

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 trading securities in deferred compensation trusts to fund obligations under certain non-qualified deferred compensation plans. The securities’ fair values, which are recorded as other noncurrent assets, are determined based upon quoted prices from active markets and classified within Level 1 of the valuation hierarchy. 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 Company’s trading securities and deferred compensation obligations each totaled $5.6 million and $5.8 million as of June 30, 2018 and March 31, 2018, respectively. The fair value of the Company’s long-term debt is disclosed in Note 15.

Stock-Based Compensation [Abstract]
Stock-Based Compensation	Note 5: Stock-Based Compensation The Company’s stock-based incentive programs consist of the following: (1) a long-term incentive compensation program for officers and other executives that consists of stock awards, stock options, and performance-based stock awards granted for retention and performance, (2) a discretionary equity program for other management and key employees, and (3) stock awards for non-employee directors. 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 $2.0 million and $2.3 million for the three months ended June 30, 2018 and 2017, respectively. The performance component of awards granted under the Company’s long-term incentive plan during the first quarter of fiscal 2019 is based upon both 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. The fair value of stock-based compensation awards granted during the three months ended June 30, 2018 and 2017 were as follows: Three months ended June 30, 2018 2017 Shares Fair Value Per Award Shares Fair Value Per Award Stock options 0.2 $ 7.81 0.2 $ 7.30 Restricted stock awards 0.2 $ 17.90 0.2 $ 15.90 Performance stock awards 0.2 $ 17.90 0.2 $ 15.90 The Company used the following assumptions in determining fair value for stock options: Three months ended June 30, 2018 2017 Expected life of awards in years 6.3 6.4 Risk-free interest rate 2.8 % 1.9 % Expected volatility of the Company's stock 39.7 % 44.3 % Expected dividend yield on the Company's stock 0.0 % 0.0 % As of June 30, 2018, 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 $ 3.6 3.1 Restricted stock awards 8.4 3.1 Performance stock awards 6.8 2.1 Total $ 18.8 2.7

Income Taxes [Abstract]
Income Taxes	Note 8: Income Taxes The Company’s effective tax rate for the three months ended June 30, 2018 and 2017 was 18.2 percent and 13.4 percent, respectively. The effective tax rate for the first quarter of fiscal 2019 is higher than the first quarter of the prior year, primarily due to a $3.5 million benefit for a Hungarian development tax credit in the prior year, partially offset by the reversal of a valuation allowance on deferred tax assets in a foreign jurisdiction during the first quarter of fiscal 2019. On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the “Tax Act”). Shortly after the Tax Act was enacted, the SEC issued accounting guidance which provides a one-year measurement period during which a company may complete its accounting for the impacts of the Tax Act. To the extent a company’s accounting for certain income tax effects of the Tax Act is incomplete, the company may determine a reasonable estimate for those effects and record a provisional estimate in its financial statements. If a company cannot determine a provisional estimate to be included in the financial statements, it should continue to apply the provisions of the tax laws that were in effect immediately prior to the Tax Act being enacted. During fiscal 2018, the Company recorded provisional discrete tax charges totaling $38.0 million related to the Tax Act. The Company adjusted its U.S. deferred tax assets by $19.0 million due to the reduction in the U.S. federal corporate tax rate. This net reduction in deferred tax assets also included the estimated impact on the Company’s net state deferred tax assets. In addition, the Company recorded a $19.0 million charge for the transition tax required under the Tax Act. The Company is in process of evaluating whether to utilize its deferred tax attributes against the transition tax. If the Company elects not to do so, it expects to pay the estimated $19.0 million transition tax liability over the next eight years, beginning with a payment of approximately $1.5 million during fiscal 2019. The Company is also awaiting additional technical guidance on the treatment of the transition tax and its impact on fiscal year taxpayers. In addition, the Company is analyzing the state tax impact of the transition tax and the associated impact on the realizability of tax attributes and the impact of the global intangible low taxed income (“GILTI”) provision of the Tax Act on its deferred tax attributes. The Company has elected to record the tax effects of the GILTI provision as a period expense in the applicable tax year. The Company has not yet completed its accounting for the income tax effects of certain elements of the Tax Act. In regard to the reduction in the U.S. corporate tax rate, the Company will continue to analyze the impacts of the Tax Act through the finalization of its fiscal 2018 U.S. federal tax return. In regard to the transition tax, the Company is awaiting further interpretative guidance, continuing to assess available tax methods and elections, and continuing to gather additional information in order to more precisely compute the amount of this tax. Previously, the Company’s practice and intention was to reinvest, with certain insignificant exceptions, the earnings of its non-U.S. subsidiaries outside of the U.S. As a result, the Company did not record U.S. deferred income taxes or foreign withholding taxes for these earnings. The Company is currently analyzing its global working capital requirements and the potential tax liabilities that would be incurred if its non-U.S. subsidiaries distribute cash to the U.S. parent, which include local country withholding taxes and potential U.S. state taxes. The Company expects to complete its analysis of the accounting guidance related to the Tax Act and its evaluation of the impacts of the Tax Act in the second or third quarter of fiscal 2019. The Company is continuing to analyze the provisions of the Tax Act to determine the impact on its fiscal 2019 effective tax rate. For the first quarter of fiscal 2019, the Company has recorded an estimate for GILTI, the base erosion anti-abuse tax provision of the Tax Act, new limits on the deductibility of executive compensation, and the state tax implications of these provisions. As of June 30, 2018, valuation allowances against deferred tax assets in certain foreign jurisdictions totaled $33.7 million and valuation allowances against certain U.S. deferred tax assets totaled $7.0 million, as it is more likely than not these assets will not be realized based upon historical financial results. During the first quarter of fiscal 2019, the Company recorded a benefit of $2.0 million related to the reversal of a valuation allowance for deferred tax assets in a foreign jurisdiction after determining it was more likely than not the deferred tax assets would be realized in the future. The Company will continue to provide a valuation allowance against its net deferred tax assets in each of the applicable jurisdictions until the need for a valuation allowance is eliminated. The need for a valuation allowance is eliminated when the Company determines it is more likely than not the deferred tax assets will be realized. 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 estimates that reductions to unrecognized tax benefits for the remainder of fiscal 2019 will total $2.2 million due mainly to lapses in statutes of limitations, which, if recognized, would have a $1.6 million favorable impact on its effective tax rate.

As of June 30, 2018, domestic letters of credit totaled $4.3 million, resulting in available capacity under the Company’s revolving credit facility of $108.6 million. The Company also maintains credit agreements for its foreign subsidiaries, with outstanding short-term borrowings as of June 30, 2018 and March 31, 2018 of $31.1 million and $31.9 million, respectively. As of June 30, 2018, the Company’s foreign unused lines of credit totaled $1.2 million. In aggregate, the Company had total available lines of credit of $109.8 million as of June 30, 2018. Provisions in the Company’s amended and restated 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. In addition, the term loans require prepayments, as defined in the credit agreement, in the event the Company’s annual excess cash flow exceeds defined levels or in the event of certain asset sales. The Company is also subject to leverage ratio covenants, the most restrictive of which requires the Company to limit its consolidated indebtedness, less a portion of its cash balance, both as defined by the credit agreements, to no more than three and one-quarter times consolidated net earnings before interest, taxes, depreciation, amortization, and certain other adjustments (“Adjusted EBITDA”). 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 June 30, 2018. 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 June 30, 2018 and March 31, 2018, 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 $148.2 million and $153.1 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.

Contingencies and Litigation [Abstract]
Contingencies and Litigation	Note 16: Contingencies and Litigation Environmental The Company has recorded environmental investigation and remediation accruals related to soil and groundwater contamination at two manufacturing facilities in the United States, one of which the Company no longer owns, and at its former manufacturing facility in the Netherlands, along with accruals for lesser environmental matters at certain other facilities in the United States and Brazil. 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 $17.1 million and $16.7 million as of June 30, 2018 and March 31, 2018, 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. In the opinion of management, the liabilities, if any, which may ultimately result from such lawsuits or proceedings are not expected to have a material adverse effect on the Company’s financial position.

General [Abstract]
New Accounting Guidance	New Accounting Guidance Revenue Recognition In May 2014, the Financial Accounting Standards Board (“FASB”) issued new guidance that outlines a comprehensive model for entities to use in accounting for revenue arising from contracts with customers. The core principle of the new guidance is that companies are to recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The new guidance also includes a cohesive set of disclosure requirements intended to provide users of financial statements with comprehensive information about revenue arising from contracts with customers. The Company adopted this new guidance for its first quarter of fiscal 2019 using the modified-retrospective transition method. The Company assessed customer contracts and evaluated contractual provisions in light of the new guidance. Through its evaluation process, the Company identified a limited number of customer contracts that provide an enforceable right to payment for customized products, which require revenue recognition prior to the product being shipped to the customer. As a result of its adoption of the new guidance, the Company recorded an increase of $0.7 million to retained earnings as of April 1, 2018, along with related balance sheet reclassifications. The increase to retained earnings reflects $3.0 million of net sales that, had the new guidance been in effect, the Company would have recognized as of March 31, 2018. See Note 2 for additional information regarding revenue recognition. Income Taxes: Intra-Entity Transfers of Assets Other Than Inventory In October 2016, the FASB issued new guidance related to income tax accounting for intercompany asset transfers. This new guidance requires companies to recognize the income tax effects of intercompany asset transfers other than inventory at the transaction date. The income tax effects of these transfers were previously deferred. The Company adopted this new guidance for its first quarter of fiscal 2019 using the modified-retrospective transition method. Upon adoption, the Company recorded a decrease to retained earnings of $8.3 million as of April 1, 2018. Statement of Cash Flows: Restricted Cash In November 2016, the FASB issued new guidance that requires restricted cash to be included with cash and cash equivalents when reconciling the beginning and ending balances presented within the statement of cash flows. The Company adopted this new guidance for its first quarter of fiscal 2019 using the retrospective transition method. As a result, all prior period information has been recast to be comparable to the new presentation requirements. See Note 10 for information regarding the Company’s restricted cash. Leases In February 2016, the FASB issued new comprehensive lease accounting guidance that supersedes existing lease accounting guidance. Upon adoption of this new guidance, the Company will be required to recognize most leases on its balance sheet. This guidance is effective for the Company’s first quarter of fiscal 2020. The Company is currently evaluating the impact this guidance will have on its consolidated financial statements. Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income In February 2018, the FASB issued new guidance related to the accounting for certain stranded income tax effects in accumulated other comprehensive income (loss) resulting from tax reform legislation that was enacted in the U.S. in December 2017. This guidance permits companies to reclassify stranded income tax effects to retained earnings and is effective for the Company’s first quarter of fiscal 2020. The Company is currently evaluating the impact this guidance will have on its consolidated financial statements. The cumulative effects on the Company’s consolidated balance sheet, as of April 1, 2018, resulting from the adoption of new accounting guidance were as follows: Adjustments Due to New Accounting Guidance Balance as of March 31, 2018 Revenue Recognition Intra-entity Transfers of Assets Balance as of April 1, 2018 ASSETS Inventories $ 191.3 $ (2.0 ) $ - $ 189.3 Other current assets 70.1 3.0 (8.3 ) 64.8 Deferred income taxes 96.9 (0.2 ) - 96.7 LIABILITIES AND SHAREHOLDERS' EQUITY Deferred income taxes $ 9.9 $ 0.1 $ - $ 10.0 Retained earnings 394.9 0.7 (8.3 ) 387.3
