Note 16. Commitments and Contingencies Asbestos In 1986, we acquired a brake business, which we subsequently sold in March 1998 and which is accounted for as a discontinued operation in the accompanying statement of operations. When we originally acquired this brake business, we assumed future liabilities relating to any alleged exposure to asbestos-containing products manufactured by the seller of the acquired brake business. In accordance with the related purchase agreement, we agreed to assume the liabilities for all new claims filed on or after September 2001. Our ultimate exposure will depend upon the number of claims filed against us on or after September 2001, and the amounts paid for settlements, awards of asbestos-related damages, and defense of such claims. At September 30, 2019, approximately 1,500 cases were outstanding for which we may be responsible for any related liabilities. Since inception in September 2001 through September 30, 2019, the amounts paid for settled claims are approximately $30.5 million. We do not have insurance coverage for the indemnity and defense costs associated with the claims we face. In evaluating our potential asbestos-related liability, we have considered various factors including, among other things, an actuarial study of the asbestos related liabilities performed by an independent actuarial firm, our settlement amounts and whether there are any co-defendants, the jurisdiction in which lawsuits are filed, and the status and results of such claims. As is our accounting policy, we consider the advice of actuarial consultants with experience in assessing asbestos-related liabilities to estimate our potential claim liability ; and perform an annual actuarial evaluation in the third quarter of each year and whenever events or changes in circumstances indicate that additional provisions may be necessary. The methodology used to project asbestos-related liabilities and costs in our actuarial study considered: (1) historical data available from publicly available studies; (2) an analysis of our recent claims history to estimate likely filing rates into the future; (3) an analysis of our currently pending claims; and (4) an analysis of our settlements to date in order to develop average settlement values. Based on the information contained in the actuarial study and all other available information considered by us, we have concluded that no amount within the range of settlement payments and awards of asbestos-related damages was more likely than any other and, therefore, in assessing our asbestos liability we compare the low end of the range to our recorded liability to determine if an adjustment is required. As related to our potential asbestos-related liability, in 2018, we were a defendant in an asbestos liability case in California, in which we were found liable for $7.6 million in compensatory damages. We are pursuing all rights of appeal of this case, and during the appeal process, interest will accrue at a rate of ten percent (10%) per annum. During the fourth quarter of 2018, our actuarial firm revised the results of its August 31, 2018 study. Based upon the results of the revised actuarial study, in December 2018, we increased our asbestos liability to $46.7 million and recorded an incremental pre-tax provision of $10.1 million in earnings (loss) from discontinued operations. In accordance with our policy to perform an annual actuarial evaluation in the third quarter of each year, an updated actuarial study was performed as of August 31, 2019. The results of the August 31, 2019 study included an estimate of our undiscounted liability for settlement payments and awards of asbestos-related damages, excluding legal costs and any potential recovery from insurance carriers, ranging from $52 million to $90.6 million for the period through 2064. The change from the revised prior year study, which was performed in the fourth quarter of 2018, was a $5.3 million increase for the low end of the range and a $6.7 million increase for the high end of the range. The increase in the estimated undiscounted liability from the revised prior year study at both the low end and high end of the range reflects our actual experience, our historical data and certain assumptions with respect to events that may occur in the future. Based upon the results of the August 31, 2019 actuarial study, in September 2019, we increased our asbestos liability to $52 million, the low end of the range, and recorded an incremental pre-tax provision of $9.7 million in earnings (loss) from discontinued operations in the accompanying statement of operations. Future legal costs, which are expensed as incurred and reported in earnings (loss) from discontinued operations in the accompanying statement of operations, are estimated, according to the updated study, to range from $50.6 million to $85.2 million for the period through 2064. We plan to perform an annual actuarial evaluation during the third quarter of each year for the foreseeable future and whenever events or changes in circumstances indicate that additional provisions may be necessary. Given the uncertainties associated with projecting such matters into the future and other factors outside our control, we can give no assurance that additional provisions will not be required. We will continue to monitor events and changes in circumstances surrounding these potential liabilities in determining whether to perform additional actuarial evaluations and whether additional provisions may be necessary. At the present time, however, we do not believe that any additional provisions would be reasonably likely to have a material adverse effect on our liquidity or consolidated financial position. Other Litigation We are currently involved in various other legal claims and legal proceedings (some of which may involve substantial amounts), including claims related to commercial disputes, product liability, employment, and environmental. Although these legal claims and legal proceedings are subject to inherent uncertainties, based on our understanding and evaluation of the relevant facts and circumstances, we believe that the ultimate outcome of these matters will not, either individually or in the aggregate, have a material adverse effect on our business, financial condition or results of operations. We may at any time determine that settling any of these matters is in our best interests, which settlement may include substantial payments. Although we cannot currently predict the specific amount of any liability that may ultimately arise with respect to any of these matters, we will record provisions when the liability is considered probable and reasonably estimable. Significant judgment is required in both the determination of probability and the determination as to whether an exposure can be reasonably estimated. As additional information becomes available, we reassess our potential liability related to these matters. Such revisions of the potential liabilities could have a material adverse effect on our business, financial condition or results of operations. Warranties We generally warrant our products against certain manufacturing and other defects. These product warranties are provided for specific periods of time of the product depending on the nature of the product. As of September 30, 2019 and 2018, we have accrued $20.6 million and $24.1 million, respectively, for estimated product warranty claims included in accrued customer returns. The accrued product warranty costs are based primarily on historical experience of actual warranty claims. The following table provides the changes in our product warranties (in thousands): Three Months Ended September 30, Nine Months Ended September 30, 2019 2018 2019 2018 Balance, beginning of period $ 22,086 $ 21,705 $ 19,636 $ 20,929 Liabilities accrued for current year sales 26,112 25,748 76,791 70,126 Settlements of warranty claims (27,573 ) (23,396 ) (75,802 ) (66,998 ) Balance, end of period $ 20,625 $ 24,057 $ 20,625 $ 24,057
