BorgWarner Inc. disclosed Friday that it should restate the 2015 to 2016 statements included in the 2017 annual report, because of the re-evaluation of accounting liabilities related estimated value of incurred but not reported asbestos-related claims (IBNR claims). The automotive parts supplier said it will also make revisions to 2013 and 2014 financial data, and the quarterly information for 2016, to reflect these changes. The company said it will determine an appropriate estimated liability for IBNR claims to be accrued as of Dec. 31, 2012 as an adjustment to earnings. The charge originally taken in the fourth quarter of 2016 will be reversed, and the company will make appropriate adjustments to the valuation of insurance assets that are responsive to asbestos-related claims. The stock, which was still inactive in premarket trade, has shed 4.4% year to date, while the S&P 500 has gained 4.1%.
