Note 21. Commitments and contingencies Woodward is currently involved in claims, pending or threatened litigation or other legal proceedings, investigations and/or regulatory proceedings arising in the normal course of business, including, among others, those relating to product liability claims, employment matters, workers compensation claims, contractual disputes, product warranty claims and alleged violations of various laws and regulations. Woodward accrues for known individual matters using estimates of the most likely amount of loss where it believes that it is probable the matter will result in a loss when ultimately resolved and such loss is reasonably estimable. Legal costs are expensed as incurred and are classified in Selling, general and administrative expenses on the Condensed Consolidated Statements of Earnings. Woodward is partially self-insured in the United States for healthcare and workers compensation up to predetermined amounts, above which third party insurance applies. Management regularly reviews the probable outcome of related claims and proceedings, the expenses expected to be incurred, the availability and limits of the insurance coverage, and the established accruals for liabilities. While the outcome of pending claims, legal and regulatory proceedings, and investigations cannot be predicted with certainty, management believes that any liabilities that may result from these claims, proceedings and investigations will not have a material effect on Woodwards liquidity, financial condition, or results of operations. In the event of a change in control of Woodward, as defined in change-in-control agreements with its current corporate officers, Woodward may be required to pay termination benefits to any such officer if such officers employment is terminated within two years following the change of control. On April 9, 2019, German wind turbine manufacturer, Senvion GmbH (Senvion), a customer of Woodwards renewables business, announced that it filed for self-administration insolvency proceedings. In parallel, Senvion announced that it has sought financing to secure the continuation of its operations, which it announced may allow the company to successfully exit the insolvency process. On April 17, 2019, Senvion announced that it signed a 100,000 bulk loan agreement with its lenders and major bondholders to enable the company to continue its business activities. As the proceedings are in the early stages, Woodward will continue to analyze any financial and commercial impact of the Senvion insolvency proceedings, including any adverse effect the proceedings may have on its financial results. Management believes any such effect would not be material to Woodward as a whole, although it could potentially be significant to Woodwards renewables business. ?
