Our operations are subject to regulation under a wide variety of U.S. federal and state and non-U.S. laws, regulations and other government requirements -- including, among others, those relating to the environment, health and safety, labor and employment, data privacy, tax, trade and health care. There can be no assurance that laws, regulations and government requirements will not be changed, applied or interpreted in ways that will require us to modify our operations and objectives or affect our returns on investments by restricting existing activities and products, or subjecting us to increased costs. For example, as part of our business, we are subject to increasingly stringent federal, state, local and international laws governing the protection of the environment. We have incurred significant capital, operating and other expenditures complying with applicable environmental laws and regulations. In addition, new environmental laws, regulations or other requirements, including with respect to GHG emissions or climate change, may cause us to incur increased and unexpected compliance costs. Moreover, there has historically been a lack of consistent climate legislation, which has created and continues to create economic and regulatory uncertainty. Our environmental expenditures include, among other areas, those related to air and water quality, waste disposal and the cleanup of contaminated soil and groundwater, including situations where we have been identified as a potentially responsible party. Moreover, we may be directly impacted by, and are working to manage, the risks and costs to us, our customers and our vendors of the effects of climate change, GHGs, and the availability of energy and water resources. These risks include the potentially adverse impact on forestlands, which are a key resource in the production of our products, increased product costs and a change in the types of products that customers purchase. There can be no assurance that future remediation requirements and compliance with existing and new laws and requirements will not require significant expenditures, or that existing reserves for specific matters will be adequate to cover future costs. We could also incur substantial fines or sanctions, enforcement actions (including orders limiting our operations or requiring corrective measures), natural resource damages claims, cleanup and closure costs, third-party claims for property damage and personal injury and reputational harm as a result of violations of, or liabilities under, environmental laws, regulations, codes and common law. The amount and timing of environmental expenditures is difficult to predict, and, in some cases, liability may be imposed without regard to contribution or to whether we knew of, or caused, the release of hazardous substances. Our global operations subject us to complex and evolving U.S and international data privacy laws and regulations, such as European’s Union General Data Protection Regulation (“GDPR”), the California Consumer Privacy Act of 2018 (“CCPA”) and the California Privacy Rights Act ("CPRA"), and China’s Personal Information Protection Law (“PIPL”) which came into effect as of November 1, 2021. These laws require the Company to comply with a range of compliance obligations regarding the handling of personal data. There are significant penalties for non-compliance including monetary fines, disruption of operations and reputational harm. Moreover, other states and governmental authorities around the world have introduced or passed, or are consider enacting, similar legislation which may impose varying standards and requirements on our data collection, use and processing activities. This increasingly restrictive and evolving regulatory environment at the international, federal and state level related to data privacy and data protection may require changes to our business practices and give rise to significantly expanded compliance burdens, costs and enforcement risks. Moreover, many of these laws and regulations are subject to uncertain application, interpretation or enforcement standards that could result in claims, changes to our business practices, data processing and security systems, penalties, increased operating costs or other impacts on our businesses. These laws often provide for civil penalties for violations, as well as private rights of action for data breaches that may increase data breach litigation. The Company proactively uses internal and external resources to monitor compliance with relevant legislation and continually evaluates and, where necessary, modifies its data processing practices and policies in order to comply with evolving privacy laws. Nevertheless, relevant regulatory authorities could determine that our data handling practices fail to address all the requirements of certain new laws, which could subject us to penalties and/or litigation. In addition, there is no assurance that our security controls over personal data, the training of employees and vendors on data privacy and data security, and the policies, procedures and practices we implemented or may implement in the future will prevent the improper handling of, disclosure of or access to personal data. Improper handling and disclosure of or access to personal data in violation of the GDPR, PIPL, the CCPA and/or of other data privacy and protection laws could harm our reputation, cause loss of consumer confidence, subject us to government enforcement actions (including fines), or result in private litigation against us, which could result in loss of revenue, increased costs, liability for monetary damages, fines and/or criminal prosecution, all of which could negatively affect our business and operating results. We are subject to taxes in the U.S. and various foreign jurisdictions, and changes in laws, regulation or interpretation of existing laws and regulations in the U.S. and other jurisdictions where we are subject to taxation, could increase our taxes and have an adverse effect on our financial results. In addition, the application of tax law is subject to interpretation and is subject to audit by taxing authorities. Additionally, administrative guidance can be incomplete or vary from legislative intent, and therefore the application of the tax law is uncertain. While we believe the positions reported by the Company comply with relevant tax laws and regulations, taxing authorities could interpret our application of certain laws and regulations differently. We are currently subject to tax audits in the U.S. and other taxing jurisdictions around the world. In some cases, we have appealed and may continue to appeal, assessments by taxing authorities in the court system. As such, tax controversy matters may result in previously unrecorded tax expenses, accelerated cash tax payments, higher future tax expenses, or the assessment of interest and penalties. For example, the 2015 timber monetization restructuring is currently under Internal Revenue Service examination. An unfavorable resolution in such current examination, future administrative procedures, or future tax litigation could result in material, accelerated cash tax payments as a result of all or a portion of the remaining $813 million deferred tax liability relating to the timber monetization becoming payable. See Note 15 Variable Interest Entities for more detail on the timber monetization and the 2015 restructuring. As such, tax controversy matters may result in previously unrecorded tax expenses, higher future tax expenses or the assessment of interest and penalties.
