audit could result in higher tax expense, thereby negatively impacting our results of operations. We have established contingency reserves for a variety of material, known tax exposures. As of December 31, 2020, the total amount of unrecognized tax benefits was a liability of $310.5 million, including accrued interest and penalties, net of related items. Our reserves reflect our judgment as to the resolution of the issues involved if subject to judicial review. While we believe that our reserves are adequate to cover reasonably expected tax risks, there can be no assurance that, in all instances, an issue raised by a tax authority will be resolved at a financial cost that does not exceed our related reserve, and such resolution could have a material effect on our effective tax rate, financial condition, results of operations and cash flows in the current period and/or future periods. With respect to these reserves, our income tax expense would include: (i) any changes in tax reserves arising from material changes during the period in the facts and circumstances (i.e., new information) surrounding a tax issue and (ii) any difference from the Company’s tax position as recorded in the financial statements and the final resolution of a tax issue during the period. Such resolution could increase or decrease income tax expense in our consolidated financial statements in future periods and could impact our operating cash flows.
Our business, financial condition, results of operations, and cash flows could be harmed by adverse rating actions by credit rating agencies.
Downgrades in our credit ratings, or their review or revision to a negative outlook, could adversely affect our business, financial condition, results of operations, and cash flows, and could damage perceptions of our financial strength, which could adversely affect our relationships with our agents, particularly those agents that are financial institutions or post offices, and our banking and other business relationships. In addition, adverse ratings actions could result in regulators imposing additional capital and other requirements on us, including imposing restrictions on the ability of our regulated subsidiaries to pay dividends. Also, a downgrade below investment grade will increase our interest expense under certain of our notes, our revolving credit facility, and our term loan facility, and any significant downgrade could increase our costs of borrowing money more generally or adversely impact or eliminate our access to the commercial paper market, each of which could adversely affect our business, financial condition, results of operations, and cash flows.
There can be no guarantee that we will continue to make dividend payments or repurchase stock.
For risks associated with our ability to continue to make dividend payments or repurchase shares, please see Part II, Item 5, Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities.
Our ability to remain competitive depends in part on our ability to protect our trademarks, patents, copyrights, and other intellectual property rights and to defend ourselves against potential intellectual property infringement claims.
The Western Union and WU brands, which are protected by trademark registrations in many countries, are material to our Company. The loss of the Western Union or WU trademarks or a diminution in the perceived quality of products or services associated with the names would harm our business. Similar to the Western Union and WU trademarks, the Orlandi Valuta, Vigo, Western Union Business Solutions, Pago Fácil, Quick Collect, Quick Pay, Pay@WU, Quick Cash, My WU, Western Union Convenience Pay, and other trademarks and service marks are also important to our Company and a loss of the service mark or trademarks or a diminution in the perceived quality associated with these names could harm our business.
Our intellectual property rights are an important element in the value of our business. Our failure to take appropriate actions against those who infringe upon our intellectual property could adversely affect our business, financial condition, results of operations, and cash flows.
The laws of certain foreign countries in which we do business do not always protect intellectual property rights to the same extent as do the laws of the United States. Adverse determinations in judicial or administrative proceedings in the United States or in foreign countries could impair our ability to sell our products or services or license or protect our intellectual property, which could adversely affect our business, financial condition, results of operations, and cash flows.
We own patents and patent applications covering various aspects of our processes and services. We have been, are and in the future may be, subject to claims alleging that our platform, mobile application, or other products and services infringe third-party intellectual property or other proprietary rights, both inside and outside the United States.
