|  | (In millions) |  |

U.S. federal net operating loss |  | $ | 5,707 |  |  | $ | 1,198 |  |  | $ | — |  |  | Indefinite
State losses |  | 4,560 |  |  | 194 |  |  | (40) |  |  | 2024 - 2044

Use of a portion of our U.S. federal carryforwards is subject to the limitations provided under Sections 382 and 383 of the Internal Revenue Code as well as the separate return limitation rules of Internal Revenue Service regulations. If certain substantial changes in our ownership occur, there would be an annual limitation on the amount of carryforwards that could be utilized. Unrecognized Tax Benefits: We recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based not only on the technical merits of the tax position based on tax law, but also the past administrative practices and precedents of the taxing authority. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate resolution. A reconciliation of our gross unrecognized tax benefit excluding interest and penalties is as follows:
|  | Year Ended December 31,
|  | 2024 |  | 2023 |  | 2022
|  | (In millions)
Balance at beginning of period |  | $ | 18 |  |  | $ | 23 |  |  | $ | 21 |
Reductions based on statute expirations |  | (3) |  |  | (5) |  |  | (5) |
Audit settlement |  | — |  |  | (1) |  |  | — |
Additions to state reserves for prior years |  | 4 |  |  | 1 |  |  | 7 |
Balance at end of period |  | $ | 19 |  |  | $ | 18 |  |  | $ | 23 |
Amounts which, if recognized, would affect the effective tax rate |  | $ | 19 |  |  |  |  |
In addition, we believe it is reasonably possible that our liability for unrecognized tax benefits will increase by $3 million during the next year, primarily due to additions for state filing positions taken in prior years, offset by releases from statute expirations. The following table summarizes information of our open tax years:
Jurisdiction |  | Open Tax Year
U.S. |  | 2020 - 2024
Various states |  | 2012 - 2024
Foreign |  | 2020 - 2024
