As of December 31, 2024, we have no recorded effects for Pillar Two due to our operational jurisdiction being wholly domestic. The United States has not yet enacted legislation to adopt Pillar Two.

​ The Company’s policy is to record interest and penalties related to income tax matters, as part of income tax expense. During 2024, the Company recognized an increase in its liability for unrecognized tax benefits related primarily to prior year positions and recorded in other long-term liabilities on the Consolidated Balance Sheet. This liability, if released, would affect our effective rate. A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows: ​
​ | ​ | ​ | ​ | ​ | ​ | ​
(in thousands) | ​ | 2024 |  | 2023
Balance at January 1 | ​ | $ | 1,349 | ​ | $ | 1,058
Additions based on tax positions related to the current year | ​ |  | 21 | ​ |  | 236
Additions for tax positions of prior years | ​ |  | 41 | ​ |  | 55
Balance at December 31 | ​ | $ | 1,411 | ​ | $ | 1,349
​ The Company and its subsidiaries are subject to U.S. federal and state income tax in multiple jurisdictions. In many cases, the uncertain tax positions are related to tax years that remain open and subject to examination by the relevant taxing authorities. In general, the Company’s 2021 through 2023 tax years remain open to examination. Additional years may be open to the extent attributes are being carried forward to an open year.
