At December 31, 2021, the net deferred tax liability in our Consolidated Balance Sheets was comprised of long-term deferred tax assets of $21.7 million and long-term deferred tax liabilities of $435.3 million. At December 31, 2020, the net deferred tax liability in our Consolidated Balance Sheets was comprised of long-term deferred tax assets of $29.1 million and long-term deferred tax liabilities of $356.0 million. Long-term deferred tax assets were classified as other assets, net in our Consolidated Balance Sheets. The valuation allowance in 2021 includes deferred tax assets of $26.7 million resulting from state and foreign net operating loss carryforwards, or NOLs. The valuation allowance for deferred tax assets increased in 2021 by $6.1 million primarily due to an increase in the valuation allowance related to foreign NOLs. At December 31, 2021, we had foreign NOLs of approximately $40.5 million that are available to offset future taxable income. Of that amount, approximately $14.4 million will expire from 2023 to 2032. The remaining portion has no expiration date. At December 31, 2021, we had state tax NOLs of approximately $9.4 million that are available to offset future taxable income and that will expire from 2024 to 2039. We recognize accrued interest and penalties related to unrecognized taxes as additional income tax expense. At December 31, 2021 and 2020, we had $5.6 million and $5.4 million, respectively, accrued for potential interest and penalties. The total amount of unrecognized tax benefits recorded in other liabilities as of December 31, 2021 and 2020 were $32.7 million and $36.4 million, respectively, excluding associated tax assets and including the federal tax benefit of state taxes, interest and penalties. Tax assets associated with uncertain tax positions primarily represent our estimate of the potential tax benefits in one tax jurisdiction that could result from the payment of income taxes in another jurisdiction. At December 31, 2021 and 2020, we had approximately $17.6 million and $17.5 million, respectively, in assets associated with uncertain tax positions recorded in other assets, net in our Consolidated Balance Sheets. A reconciliation of the beginning and ending amount of gross unrecognized tax benefits included as other liabilities in our Consolidated Balance Sheets was as follows:
| 2021 |  | 2020
| (Dollars in thousands)
Balance at January 1, | $ | 32,777 |  |  | $ | 38,283 |
Increase based upon tax positions of current year | 425 |  |  | 508 |
Increase based upon tax positions of a prior year | 1,464 |  |  | 487 |
Increase due to acquisitions | — |  |  | 131 |
Decrease based upon a lapse in the statute of limitations | (5,685) |  |  | (6,632) |
Balance at December 31, | $ | 28,981 |  |  | $ | 32,777 |
The total amount of unrecognized tax benefits that would impact the effective tax rate, if recognized, at December 31, 2021 and 2020 were $16.2 million and $20.1 million, respectively. Silgan and its subsidiaries file U.S. Federal income tax returns, as well as income tax returns in various states and foreign jurisdictions. We expect the Internal Revenue Service, or IRS, will complete its review of the 2020 tax year with no change to our filed tax return. We have been accepted into the Compliance Assurance Program for the 2022 tax year which provides for the review by the IRS of tax matters relating to our tax return prior to filing. We are subject to examination by state and local tax authorities generally for the period mandated by statute, with the exception of states where waivers of the statute of limitations have been executed. The earliest open period for a state audit is 2015. Our foreign subsidiaries are generally not subject to examination by tax authorities for periods before 2008, and we have contractual indemnities with third parties with respect to open periods that predate our ownership of certain foreign subsidiaries. Subsequent periods may be examined by the relevant tax authorities. In the next twelve months, it is reasonably possible that our reserve for unrecognized tax benefits will decrease by approximately $3.2 million primarily related to tax attributes acquired from and expenses related to certain acquisitions, as we anticipate the expiration of the applicable statute of limitations with respect to certain tax matters. For certain of our foreign subsidiaries where we expect to be indefinitely reinvested, we estimate that the unremitted earnings as of December 31, 2021 are approximately $110.0 million. The amount of unrecognized deferred tax liabilities on these indefinitely reinvested earnings is estimated to be approximately $5.8 million.
