Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	18. Commitments and Contingencies Pending Litigation - Brazil Tax Assessments In connection with our May 1, 2012, acquisition of the Mead C&OP business, we assumed all of the tax liabilities for the acquired foreign operations including Tilibra. For further information, see "Note 11. Income Taxes - Brazil Tax Assessments" for details on tax assessments issued by the FRD against Tilibra challenging the tax deduction of goodwill from Tilibra's taxable income for the years 2007 through 2010. If the FRD's initial position is ultimately sustained, payment of the amount assessed would materially and adversely affect our cash flow in the year of settlement. Brazil Tax Credits In May 2021, the Supreme Court of Brazil issued its final ruling in a leading case related to the computation of certain indirect taxes which provides that the indirect tax base should not include the gross amount of the value-added tax known as “ICMS.” The Supreme Court further ruled that taxpayers can recognize future operating credits ("Tax Credits") for excess indirect tax payments from past periods due to the inclusion of ICMS in the indirect tax base to the extent the taxpayer had filed judicial challenges seeking to recover excess tax payments prior to March 15, 2017 and for any excess tax payments made after March 15, 2017. Tilibra, one of our Brazilian subsidiaries, filed legal actions requesting recovery of these excess tax payments by way of future Tax Credits covering various time periods prior to March 15, 2017. Some of these cases have been finally decided in a court of law in favor of Tilibra, while others are still pending a final decision which we expect to issue in the future based on the Supreme Court decision. In the second quarter, the Company recorded Tax Credits in the amount of $9.1 million with respect to the finally decided cases as Other income, net. In addition, the Tax Credits resulted in additional income tax expense of $3.1 million. Final decisions in the remaining legal actions Tilibra has filed will result in additional Tax Credits, and the amount of these Tax Credits, in the aggregate, may be material. Other Pending Litigation We are party to various lawsuits and regulatory proceedings, primarily related to alleged patent infringement, as well as other claims incidental to our business. In addition, we may be unaware of third-party claims of intellectual property infringement relating to our technology, brands, or products, and we may face other claims related to business operations. Any litigation regarding patents or other intellectual property could be costly and time-consuming and might require us to pay monetary damages or enter into costly license agreements. We also may be subject to injunctions against development and sale of certain of our products. It is the opinion of management that (other than the Brazil Tax Assessments) the ultimate resolution of currently outstanding matters will not have a material adverse effect on our financial condition, results of operations or cash flow. However, there is no assurance that we will ultimately be successful in our defense of any of these matters or that an adverse outcome in any matter will not affect our results of operations, financial condition or cash flow. Further, future claims, lawsuits and legal proceedings could materially and adversely affect our business, reputation, results of operations and financial condition.
