A non-U.S. corporation, such as the Company, will be treated as a "passive foreign investment company," or PFIC, for U.S. federal income tax purposes for a taxable year if either (1) at least 75% of its gross income for such taxable year consists of certain types of "passive income" or (2) at least 50% of the value of the corporation's assets (generally determined on the basis of a quarterly average) during such year produce or are held for the production of passive income. For purposes of these tests, "passive income" includes dividends, interest, net gains from the sale or exchange of investment property and rents and royalties other than rents and royalties that are received from unrelated parties in connection with the active conduct of a trade or business but does not generally include income derived from the performance of services. In addition, a non-U.S. corporation is treated as holding directly and receiving directly its proportionate share of the assets and income of any other corporation in which it directly or indirectly owns at least 25% (by value) of such corporation's stock.
Based on the composition of our income and assets, we believe we were not a PFIC for the taxable year ended December 31, 2022 and we do not anticipate being a PFIC for the current taxable year or foreseeable future taxable years. There can be no assurance, however, that we were not a PFIC for the taxable year ended December 31, 2022 or that we will not be a PFIC for the current taxable year or foreseeable future taxable years. The application of the PFIC rules is subject to uncertainty in several respects, and we must make a separate determination after the close of each taxable year as to whether we were a PFIC for such year. Moreover, we believe that any income we receive from offshore drilling service contracts should not be treated as passive income under the PFIC rules and that the assets we own and utilize to generate this income should not be treated as passive assets. Because there are uncertainties in the application of the relevant rules, however, it is possible that the Internal Revenue Service (the "IRS") may challenge our classification of such income or assets as non-passive, which could cause us to become classified as a PFIC for the current or subsequent taxable years.
If we were treated as a PFIC for any taxable year during which a U.S. Holder (as defined in "Item 10.E. Taxation-U.S. Federal Income Tax Considerations-General") held a common share, certain adverse U.S. federal income tax consequences could apply to such U.S. Holder. See "Item 10.E. Taxation-U.S. Federal Income Tax Considerations-Passive Foreign Investment Company Considerations" for a more comprehensive discussion.
