Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Organization | Organization Mueller Water Products, Inc., a Delaware corporation, together with its consolidated subsidiaries, operates in two business segments: Mueller Co. and Anvil. Mueller Co. manufactures valves for water and gas systems, including butterfly, iron gate, tapping, check, knife, plug and ball valves, as well as dry-barrel and wet-barrel fire hydrants and metering systems, and provides leak detection and pipe condition assessment products and services for the water infrastructure industry. Anvil manufactures and sources a broad range of products, including a variety of fittings, couplings, hangers and related products. The “Company,” “we,” “us” or “our” refer to Mueller Water Products, Inc. and its subsidiaries. With regard to the Company's segments, “we,” “us” or “our” may also refer to the segment being discussed. In July 2014, Mueller Co. acquired a 49% ownership interest in an industrial valve joint venture for $1.7 million. Due to substantive control features in the operating agreement, all of the joint venture's assets, liabilities and results of operations are included in our consolidated financial statements. In the three and six months ended March 31, 2015, we included an adjustment for the loss attributable to noncontrolling interest in selling, general and administrative expenses. Noncontrolling interest is recorded at its carrying value, which approximates fair value. Unless the context indicates otherwise, whenever we refer to a particular year, we mean our fiscal year ended or ending September 30 in that particular calendar year. Our consolidated financial statements are prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”), which require us to make certain estimates and assumptions that affect the reported amounts of assets, liabilities, sales and expenses and the disclosure of contingent assets and liabilities for the reporting periods. Actual results could differ from those estimates. All significant intercompany balances and transactions have been eliminated. In our opinion, all normal and recurring adjustments that we consider necessary for a fair financial statement presentation have been made. Certain reclassifications have been made to previously reported amounts to conform to the current presentation. The condensed consolidated balance sheet data at September 30, 2014 was derived from audited financial statements, but does not include all disclosures required by GAAP. In May 2014, the Financial Accounting Standards Board issued new guidance for the recognition of revenue. This new guidance applies to us beginning with our first quarter of fiscal 2019 and early adoption is not permitted. We are in the early stages of evaluating the impact of the adoption of this guidance on our future financial statements and related disclosures and we have not yet reached any conclusions.
