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, 2013. 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 nine months of fiscal 2014 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, 2013.

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). During the first quarter of fiscal 2013, the Company identified an error related to certain commodity hedges that should have been deemed ineffective in the fourth quarter of fiscal 2012, which overstated pre-tax earnings by $0.5 million in the first quarter of fiscal 2013. The Company does not believe that the impact of these errors is material to its financial statements for any prior periods, to the three or nine months ended December 31, 2013, or its projected full year financial results for fiscal 2014.

New accounting pronouncement: In February 2013, the Financial Accounting Standards Board (“FASB”) issued an accounting standards update that requires entities to present reclassifications by component when reporting changes in accumulated other comprehensive income. In addition, the Company is required to present, either on the face of the statement where net income is presented or in the notes, certain significant amounts reclassified out of accumulated other comprehensive income within the respective line items of the consolidated statement of operations. The Company adopted this guidance in the first quarter of fiscal 2014. See Note 18 for additional information.
