As of December 31, 2021, the Company had federal, state and foreign gross research and other tax credit carryforwards of $52.3. Included in the total carryforwards are $12.7 of credits that can be carried forward indefinitely while the remaining credits expire at various dates through 2037. The Company also had federal, state and foreign gross net operating loss and capital loss carryforwards of $93.3. Included in the total carryforwards are $51.7 of losses that can be carried forward indefinitely while the remaining losses expire at various dates through 2039. Although the Company believes that its tax positions are consistent with applicable U.S. federal, state and international laws, it maintains certain tax reserves as of December 31, 2021 in the event its tax positions were to be challenged by the applicable tax authority and additional tax assessed upon audit. A reconciliation of the beginning and ending amount of gross unrecognized tax benefits is as follows:
|  | Years Ended December 31, |
|  | 2021 |  |  | 2020 |  |  | 2019 |
Balance at beginning of year |  | $ | 47.0 |  |  | $ | 43.5 |  |  | $ | 32.7 |
(Decreases) increases for prior years |  |  | (0.6 | ) |  |  | 1.1 |  |  |  | 9.3 |
Increases for the current year |  |  | 2.3 |  |  |  | 6.8 |  |  |  | 3.2 |
Reductions related to expiration of statutes of limitations and audit settlements |  |  | (5.6 | ) |  |  | (4.4 | ) |  |  | (1.7 | )
Balance at end of year |  | $ | 43.1 |  |  | $ | 47.0 |  |  | $ | 43.5 |
The net decrease in gross unrecognized tax benefits was primarily attributable to the release of a reserve related to federal research tax credits and the expiration of the statutes of limitations, partially offset by the addition of a reserve related to foreign withholding taxes. The Company accrues interest and, if applicable, penalties for any uncertain tax positions. Interest and penalties are classified as a component of income tax expense. As of December 31, 2021, 2020 and 2019, the Company accrued interest on unrecognized tax benefits of approximately $1.0, $0.7 and $0.5, respectively. Over the next 12 months it is reasonably possible that the Company may recognize approximately $3.6 of previously net unrecognized tax benefits, excluding interest and penalties, related to various U.S. federal, state and foreign tax positions, primarily due to the expiration of statutes of limitations. The Company is subject to examination by U.S. federal, state and foreign tax authorities. The U.S. federal statute of limitations remains open for tax years 2018 through the present. The statute of limitations for the Company’s tax filings in other jurisdictions varies between fiscal years 2015 through present. The Company has certain federal credit carryforwards and state tax loss and credit carryforwards that are open to examination for tax years 2002 through the present. In addition, the 2017 transition tax remains open for examination. On a quarterly basis, the Company evaluates both positive and negative evidence that affects the realizability of net deferred tax assets and assesses the need for a valuation allowance. The future benefit to be derived from its deferred tax assets is dependent upon its ability to generate sufficient future taxable income to realize the assets. During 2021, the Company decreased its valuation allowance by $4.4, primarily related to the release of the valuation allowance on its Austrian entities. During 2020, the Company increased its valuation allowance by $3.2. This increase was primarily related to certain foreign net operating loss carry-forward amounts. During 2019, the Company increased its valuation allowance by $9.4. This increase was primarily attributable to the addition of historical valuation allowances for ESI and its subsidiaries which were included as a result of the ESI Merger during the quarter ended March 31, 2019. No provision has been made for deferred taxes related to remaining historical outside basis differences in certain of the Company’s non-US subsidiaries. The Company continues to assert indefinite reinvestment with respect to certain outside basis differences as of December 31, 2021. Determination of the amount of unrecognized deferred tax liability on such outside basis differences is not practicable because the amount of such liability, if any, is dependent upon various circumstances and factors, including availability of tax planning. Certain of the Company’s subsidiaries have obtained tax rate reductions or tax holidays under government-sponsored incentive programs. For example, a Singapore subsidiary of the Company obtained a tax holiday in Singapore. The benefits of the holiday were approximately $0.4 ($0.01 per share) in 2021 and $1.7 ($0.03 per share) in 2020. The tax holiday in Singapore expired in June 2021 and another tax holiday was granted and expires in June 2026.
