A reconciliation of the U.S. statutory federal income tax rate to the Company’s effective income tax rate is as follows:
| Year Ended December 31,
| 2022 |  | 2021 |  | 2020
Federal statutory rate | 21.0 | % |  | 21.0 | % |  | 21.0 | %

Other | (0.1) |  |  | (1.9) |  |  | 1.1 |
Effective income tax rate | 10.7 | % |  | (3.7) | % |  | 23.0 | %
For the year ended December 31, 2022, the effective tax rate was higher as compared to the year ended December 31, 2021, primarily due to the 2021 effective tax rate impact, net of officer compensation limitation provisions, related to the 2021 compensation charge of $90,721 to Deferred compensation plan expenses to record reallocated deferred compensation plan liabilities at fair value (see Note 12). For the years ended December 31, 2022, 2021, and 2020, the Company recognized tax benefits of $20,501, $14,890, and $954, respectively, associated with windfall tax benefits from stock‑based compensation, net of the impact from officer compensation limitation provisions. The effective tax rate for the year ended December 31, 2021 was lower as compared to the year ended December 31, 2020 primarily due to the tax benefits noted above. The following is a summary of the significant components of the Company’s deferred tax assets and liabilities:
| December 31,

Total deferred tax liabilities | (76,080) |  |  | (90,559) |
Net deferred tax assets (liabilities) | $ | 1,401 |  |  | $ | 6,362 |
The Company had deferred tax assets for tax credits and net operating losses, net of unrecognized tax positions, primarily related to:
Jurisdiction: | December 31, 2022 |  | Begin to Expire
U.S. Federal NOL | $ | 1,963 |  |  | Indefinite
U.S. Federal research and development credits | 592 |  |  | 2035
U.S. Federal foreign tax credits | 267 |  |  | 2029
U.S. State NOL | 676 |  |  | 2031
U.S. State research and development credits | 416 |  |  | 2030
United Kingdom (“U.K.”) NOL | 6,864 |  |  | Indefinite
U.K. research and development credits | 526 |  |  | Indefinite
Canadian research and development credit | 1,551 |  |  | 2029
As of December 31, 2022 and 2021, the Company recorded a valuation allowance against net deferred tax assets related to NOLs and tax attributes in certain jurisdictions of $3,321 and $1,899, respectively. During the year ended December 31, 2022, the Company increased the valuation allowance by $1,422, which was primarily related to the increase in the outside basis difference on equity method investments. During the year ended December 31, 2022, the Company repatriated $150,000 of undistributed previously taxed earnings generated by its foreign subsidiaries to the U.S. The repatriations were used to fund the acquisition of Power Line Systems (see Note 4). The cash repatriations did not have a material impact on Provision for income taxes for the year ended December 31, 2022. We have provided for any applicable income taxes associated with current year distributions, as well as any earnings that are expected to be distributed in the future, in the calculation of the income tax provision. No additional provision has been made for U.S. and non‑U.S. income taxes on the undistributed earnings of subsidiaries that are expected to be indefinitely reinvested. As of December 31, 2022, certain subsidiaries had approximately $439,845 of cumulative undistributed earnings that have been deemed permanently reinvested. A liability could arise if our intention to indefinitely reinvest such earnings were to change and amounts are distributed by such subsidiaries or if such subsidiaries are ultimately disposed. The potential tax implications of unremitted earnings are driven by the facts at the time of the distribution. It is not practicable to estimate the additional income taxes related to indefinitely reinvested earnings or the basis differences related to investments in subsidiaries. A reconciliation of the beginning and ending amount of the gross unrecognized tax benefits is as follows:
| Year Ended December 31,
| 2022 |  | 2021 |  | 2020
Gross unrecognized tax benefits, beginning of year | $ | 1,331 |  |  | $ | 1,223 |  |  | $ | 1,763 |
Increases for tax positions of prior years | — |  |  | 160 |  |  | 1,436 |
Decreases for tax positions of prior years | (121) |  |  | (42) |  |  | — |
Increases for tax positions related to the current year | — |  |  | — |  |  | — |
Decreases relating to settlements with taxing authorities | (35) |  |  | — |  |  | (1,723) |
Reductions as a result of lapse of the statute of limitations | (265) |  |  | (10) |  |  | (253) |
Gross unrecognized tax benefits, end of year | $ | 910 |  |  | $ | 1,331 |  |  | $ | 1,223 |
As of December 31, 2022, 2021, and 2020, the Company had total unrecognized tax benefits including interest and penalties of $1,194, $1,704, and $1,495, respectively, of which $1,181, $1,273, and $1,175, respectively, would impact the Company’s effective tax rate if recognized. The Company records accrued interest and penalties, where applicable, related to unrecognized tax benefits as part of the (Provision) benefit for income taxes. Interest expense and penalties related to unrecognized tax benefits resulted in a (decrease) increase of the (Provision) benefit for income taxes of $(89), $101, $(20) for the years ended December 31, 2022, 2021, and 2020, respectively. The cumulative accrued interest and penalties related to unrecognized tax benefits were $284, $373, and $272 as of December 31, 2022, 2021, and 2020, respectively. The Company is subject to income tax in the U.S., as well as numerous state and foreign jurisdictions. The Company is currently under audit in the U.K. for years 2018 through 2021. In addition, the Company is under audit in various other foreign taxing jurisdictions that are not material to the consolidated financial statements. The Company’s U.S. consolidated federal income tax returns for years 2019 through 2022 may be subject to examination by the Internal Revenue Service. The Company also may be subject to examination by other significant jurisdictions, including the Irish Revenue Commissioners for Irish tax purposes for years 2018 through 2022 and by the Inland Revenue Department for New Zealand Tax purposes for years 2018 through 2022.
