The net deferred tax liabilities are presented on the consolidated balance sheet in the following categories:

Long-term deferred tax assets |  | $ | 421 |  |  | $ | 372 |

|  | $ | (19 | ) |  | $ | (80 | )
[f] | Deferred income taxes have not been provided on $4.9 billion of undistributed earnings of certain foreign subsidiaries, as the Company has concluded that such earnings should not give rise to additional tax liabilities upon repatriation or are indefinitely reinvested. A determination of the amount of the unrecognized tax liability relating to the remittance of such undistributed earnings is not practicable.
[g] | Income taxes paid in cash [net of refunds] were $341 million for the year ended December 31, 2021 [2020 - $336 million].
[h] | As of December 31, 2021, the Company had domestic and foreign operating loss carryforwards of $3.0 billion and tax credit carryforwards of $84 million. Approximately $1.9 billion of the operating losses can be carried forward indefinitely. The remaining operating losses and tax credit carryforwards expire between 2022 and 2041.
[i] | As at December 31, 2021 and 2020, the Company’s gross unrecognized tax benefits were $142 million and $182 million, respectively [excluding interest and penalties], of which $126 million and $165 million, respectively, if recognized, would affect the Company’s effective tax rate. The gross unrecognized tax benefits differ from the amount that would affect the Company’s effective tax rate due primarily to the impact of the valuation allowance on deferred tax assets. A summary of the changes in gross unrecognized tax benefits is as follows:
|  | 2021 |  |  | 2020 |
Balance, beginning of year |  | $ | 182 |  |  | $ | 192 |
Increase based on tax positions related to current year |  |  | 11 |  |  |  | 27 |
Increase based on tax positions of prior years |  |  | 2 |  |  |  | — |
Increase related to acquisitions |  |  | — |  |  |  | 11 |
Settlements |  |  | (5 | ) |  |  | (1 | )
Foreign currency translation |  |  | (5 | ) |  |  | 5 |
Statute expirations |  |  | (43 | ) |  |  | (52 | )
|  | $ | 142 |  |  | $ | 182 |
As at December 31, 2021 and 2020, the Company had recorded interest and penalties on the unrecognized tax benefits of $26 million and $43 million, respectively, which reflects a decrease of $17 and $3 million in expenses related to changes in its reserves for interest and penalties in 2021 and 2020, respectively. The Company operates in multiple jurisdictions, and its tax returns are periodically audited or subject to review by both domestic and foreign tax authorities. During the next twelve months, it is reasonably possible that, as a result of audit settlements, the conclusion of current examinations or the expiration of the statute of limitations in several jurisdictions, the Company may decrease the amount of its gross unrecognized tax benefits [including interest and penalties] by approximately $73 million, of which $66 million, if recognized, would affect its effective tax rate. The Company considers its significant tax jurisdictions to include Canada, the United States, Austria, Germany, Mexico and China. With few exceptions, the Company remains subject to income tax examination in Germany for years after 2007, China, Mexico and Austria for years after 2015, Canada for years after 2016 and the U.S. federal jurisdiction after 2017.
