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, 2014. 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 2015 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, 2014. Out of period adjustments: During the second quarter of fiscal 2014, the Company recorded a customer pricing adjustment which related to prior fiscal years. The impact of this error to the second quarter of fiscal 2014 decreased pre-tax earnings by $0.6 million ($0.5 million after-tax). The Company does not believe that the impact of this error is material to its financial statements for the three or six months ended September 30, 2013. New revenue recognition accounting guidance: In May 2014, the Financial Accounting Standards Board issued new guidance that outlines a comprehensive model for entities to use in accounting for revenue arising from contracts with customers. The core principal 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. This new guidance is effective for the Company’s first quarter of fiscal 2018 and early application is not permitted. The Company is currently evaluating the impact the new guidance will have on its consolidated financial statements.
