At December 31, 2021, the Company had U.S. federal and state NOLs of approximately $1.5 billion and $0.6 billion, respectively, which are available to offset future taxable income. These amounts include approximately $237 million of losses related to stock-based compensation. The Company also has foreign NOLs of $34 million. If not utilized, the Company's U.S. federal NOLs expire starting in 2025 and ending in 2036, the state NOLs expire starting in 2022 and ending in 2036, and the foreign NOLs expire starting in 2023 and ending in 2036. The utilization of the NOLs is subject to certain limitations. The Company's U.S. federal and state income tax returns generally remain open to examination by taxing authorities until three years after the applicable NOLs have been used or expired. As of December 31, 2021, there were no unrecognized tax benefits that would impact the effective tax rate, if recognized. From time to time, the Company is subject to examinations by various tax authorities in jurisdictions in which the Company has business operations. At this time, the Company is not subject to an Internal Revenue Service examination. On April 26, 2021, the Company entered into an agreement in principle with the Australian Taxation Office ("ATO") to pay A$83 million to settle the previously disclosed outstanding audit of the Australian tax consequences of the Company’s 2015 sale of Crown Castle Australia Holdings Pty Ltd ("CCAL"), formerly a 77.6% owned Australian subsidiary of the Company ("ATO Settlement"). The sale of CCAL generated approximately $1.2 billion in net proceeds to the Company, and resulted in a gain from the disposal of discontinued operations of $979 million for the year ended December 31, 2015. On June 16, 2021, the Company entered into a definitive settlement agreement with the ATO evidencing the ATO Settlement. On July 1, 2021, the Company paid approximately $62 million (A$83 million), based on the exchange rate in effect on that date, pursuant to the ATO Settlement. The Company recognized the ATO Settlement as a charge within discontinued operations in its consolidated statement of operations and comprehensive income (loss) for the year ended December 31, 2021, as this amount represented a reduction to the gain from the disposal of discontinued operations previously reported during the year ended December 31, 2015. The Company reflected the payment pursuant to the ATO Settlement within discontinued operations in the Company's consolidated statement of cash flows for the year ended December 31, 2021. The Company regularly assesses the likelihood of additional assessments in each of the tax jurisdictions in which it has business operations. The Company has no uncertain tax positions as of December 31, 2021. Additionally, the Company does not believe any such additional assessments arising from other examinations or audits will have a material effect on the Company's financial statements. As of December 31, 2021, the Company's deferred tax assets are included in "Other assets, net" and the Company's deferred tax liabilities are included in "Other long-term liabilities" on the Company's consolidated balance sheet.
