Organization Consolidation And Presentation Of Financial Statements [Abstract] |
Additional Financial Information Disclosures | Note 2 Additional Financial Information Disclosures The consolidated condensed balance sheet at December 31, 2018 was derived from amounts included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018. Refer to the notes to the financial statements included in that report for a description of the Company’s accounting policies and for additional details of the Company’s financial condition. The details in those notes have not changed except as discussed below and as a result of normal adjustments in the interim. Warranty and After-Sale Costs The Company estimates and records provisions for warranties and other after-sale costs in the period in which the sale is recorded, based on a lag factor and historical warranty claim experience. After-sale costs represent a variety of activities outside of the written warranty policy, such as investigation of unanticipated problems after the customer has installed the product, or analysis of water quality issues. Changes in the Company’s warranty and after-sale costs reserve are as follows:
