​ Uncertain Tax Positions We account for our uncertain tax positions in accordance with ASC 740, Income Taxes (“ASC 740”). ASC 740 provides that the tax effects from an uncertain tax position can be recognized in our consolidated financial statements only if the position is more likely than not of being sustained on audit, based on the technical merits of the position. The following table summarizes the activity related to our unrecognized tax benefits: ​
​ | ​ | ​ | ​ | ​ | ​ | ​
​ |  | 2022 |  | 2021
​ | ​ | (Dollars in thousands)
Unrecognized tax benefits balance at January 1, | ​ | $ | 155 | ​ | $ | 833
Increases related to current year tax positions | ​ |  | 228 | ​ |  | 8
Decreases due to settlements of tax positions | ​ |  | — | ​ |  | (250)
Decreases due to lapsing of statute of limitations | ​ |  | (78) | ​ |  | (436)
Unrecognized tax benefits balance at December 31, | ​ | $ | 305 | ​ | $ | 155
​ The unrecognized tax benefits at December 31, 2022 and 2021, include $30,000 and $26,000, respectively, of interest related to such positions. The unrecognized tax benefits, if ultimately recognized, would reduce our annual effective tax rate. The liabilities for potential interest are included in the Consolidated Balance Sheets at December 31, 2022 and 2021. We file a U.S. federal income tax return, various U.S. state income tax returns and several foreign returns. In general, the 2019 through 2021 tax years remain subject to examination by those taxing authorities.
