​ Deferred tax assets and liabilities are recognized for the future tax consequences of differences between the carrying amounts of assets and liabilities and their respective tax bases using enacted tax rates in effect for the year in which the differences are expected to be reversed. Significant deferred tax assets and liabilities consist of the following: ​

Net deferred tax assets | ​ | $ | 120,789 | ​ | $ | 100,532
​ Of the $120.8 million and $100.5 million net deferred tax assets as of December 31, 2024 and 2023, respectively, $121.4 million and $107.9 million, respectively, were included as a net non-current deferred tax asset within other assets on the Consolidated Balance Sheets. $0.6 million and $7.4 million, respectively, were included as a net non-current deferred tax liability within other long-term liabilities on the Consolidated Balance Sheets. During the fourth quarter of 2024, we completed the transfer of certain intellectual property between certain of our legal entities in connection with simplifying our corporate legal entity structure. The tax impact of the transfer resulted in the recognition of deferred tax assets totaling approximately $23.0 million with a corresponding decrease to tax expense. As of December 31, 2024, we have recorded a total valuation allowance on $2.9 million of our U.S. domestic deferred tax assets, largely attributable to state carryforward attributes that are expected to expire before sufficient income can be realized in those jurisdictions. The remaining valuation allowance on deferred tax assets approximates $39.4 million and is associated primarily with operations in Hong Kong, Germany, China, and Switzerland. As of December 31, 2024, there is not sufficient positive evidence to conclude that such deferred tax assets, presently reduced by a valuation allowance, will more likely than not be recognized. The December 31, 2024 valuation allowance balance reflects an increase of $4.4 million during the year. As of December 31, 2024, we had U.S., foreign and state tax loss carryforwards of $31.3 million, $277.7 million, and $107.2 million, respectively. Additionally, we had $1.6 million and $30.5 million of capital loss and interest expense limitation carryforwards, respectively. Finally, we had U.S. and state tax credit carryforwards of $0.1 million and $2.3 million, respectively. The U.S. and state net operating losses, tax credits, and interest expense limitation are subject to various utilization limitations under Section 382 of the Internal Revenue Code and applicable state laws. These Section 382 limited attributes have various expiration periods through 2036 or, in the case of the interest expense limitation amount, no expiration period. Much of the foreign loss carryforwards, and $9.7 million of the federal net operating loss carry forwards, have no expiration period. We operate under a tax holiday in Singapore, China, and Malaysia. These tax holidays are in effect through June 30, 2027, December 31, 2025, and January 31, 2025, respectively. The tax holidays are conditional upon our meeting certain employment and investment thresholds. The expected benefit of these tax holidays may be limited by the impact of Pillar II global minimum tax or other actions taken by these countries. For the years ended December 31, 2024, 2023 and 2022, the impact of the tax holidays decreased foreign taxes by $12.4 million, $14.3 million, and $19.4 million, respectively, and the benefit on earnings per diluted share was $0.33, $0.38, and $0.52, respectively. As of December 31, 2024, we have undistributed earnings in certain foreign subsidiaries of approximately $36.3 million that we have indefinitely invested, and on which we have not recognized deferred taxes. Estimating the amount of potential tax is not practicable because of the complexity and variety of assumptions necessary to compute the tax. We account for uncertain tax positions by applying a minimum recognition threshold to tax positions before recognizing these positions in the consolidated financial statements. The following table provides a reconciliation of our total gross unrecognized tax benefits, which we include within other long-term liabilities on the Consolidated Balance Sheets: ​

​ The unrecognized tax benefits of $5.7 million, if recognized, will impact our effective tax rate. In accordance with our accounting policy, we recognize accrued interest and penalties related to unrecognized tax benefits as a component of tax expense. We had $0.8 million and $0.7 million of accrued interest and penalties on December 31, 2024 and 2023, respectively. With few exceptions, we are no longer subject to federal, state, or foreign income tax examinations by tax authorities for years before 2020. ​ As of January 1, 2024, the Pillar II minimum global effective tax rate of 15% enacted by the Organization for Economic Cooperation and Development (“OECD”) was effectuated. More than 140 countries agreed to enact the Pillar II global minimum tax. However, the timing of the implementation for each country varies. For the year ended December 31, 2024, we included an estimate of global minimum tax liability as a result of those countries where we conduct business that have adopted Pillar II. As countries continue to make revisions to their legislation and release additional guidance with respect to the global minimum tax, we continue to determine any potential impact in the countries in which we operate. The impact of these changes may have a material impact on our cash tax expense and tax rate.
