discount rates based on our business plans, economic projections, anticipated future cash flows and marketplace data. There are inherent uncertainties related to these factors and management’s judgment in applying these factors. Goodwill valuations have been calculated primarily using an income approach based on the present value of projected future cash flows of each reporting unit. We could be required to evaluate the carrying value of goodwill prior to the annual assessment if we experience disruptions to our business, unexpected significant declines in operating results, divestiture of a significant component of our business or sustained market capitalization declines. These types of events could result in goodwill impairment charges in the future. Impairment charges could substantially affect our business in the periods in which they are made.
Unfavorable developments in legal proceedings, investigations and other legal, environmental, compliance and regulatory matters, could impact us in a materially adverse manner.
There can be no assurance that any outcome of any litigation, investigation or other legal, environmental, compliance and regulatory matter will be favorable. Our financial results could be materially adversely affected by an unfavorable outcome to pending or future litigation and investigations, and other legal, environmental, compliance and regulatory matters. See “Legal Proceedings” (Part I, Item 3).
We are required to comply with anti-corruption laws and regulations of the U.S. government and various international jurisdictions, and our failure to comply with these laws and regulations could have a material adverse effect on our business.
We are required to comply with the anti-corruption laws and regulations of the U.S. government and various international jurisdictions, such as the U.S. Foreign Corrupt Practices Act and the UK’s Bribery Act of 2010. If we fail to comply with anti-corruption laws, we could be subject to substantial civil and criminal penalties, including regulatory fines, monetary damages and incarceration for responsible employees and managers. In addition, if our distributors or agents fail to comply with these laws, our business may also be materially adversely affected through reputational harm and penalties.
We are required to comply with environmental, health, and safety laws at our operations around the world. The costs of complying with these laws could materially adversely affect our business.
We are subject to national, state, provincial and/or local environmental, health, and safety laws and regulations in the U.S. and abroad, including those related to the disposal of hazardous waste and the emission of greenhouse gases from our manufacturing processes. These laws impose liability for the costs of, and damages resulting from, cleaning up current sites, past spills, disposals and other releases of hazardous substances. These laws are often unclear and subject to the discretion of the enforcing authorities. Compliance with existing and future environmental, health and safety laws could subject us to fees, penalties, costs or liabilities, impact our production capabilities, limit our ability to sell, expand or acquire facilities, and have a material adverse effect on our business. Laws and regulations related to the environment, product content and product safety are complex, change often, and can be open to different interpretations. In addition, we could be materially and adversely impacted by any environmental or product safety enforcement action affecting our suppliers, particularly in emerging markets.
We have accrued liabilities for the environmental clean-up of certain sites, including the eleven sites for which U.S. governmental agencies have designated us as a potentially responsible party as of our 2019 fiscal year-end, where it is probable that a loss will be incurred and the cost or amount of loss can be reasonably estimated. See “Legal Proceedings” (Part I, Item 3). However, because of the uncertainties associated with environmental assessment and remediation activities, the actual expense to remediate currently identified sites and other sites that could be identified for cleanup in the future could be higher than the liabilities accrued.
We are subject to governmental export and import control laws and regulations in the jurisdictions in which we do business that could subject us to liability or impair our ability to compete in these markets.
Export control laws and economic sanctions prohibit the shipment of some of our products to embargoed or sanctioned countries, governments and persons. While we train our employees to comply with these regulations, use third party screening software, and take other measures, we cannot guarantee that a violation will not occur. A prohibited shipment could have negative consequences, including government investigations, penalties, fines, civil
