The effective income tax rate for fiscal 2022 was impacted by tax benefits from permanent tax credits offset by valuation allowances as well as other various permanent tax adjustments and state taxes with additional expense for prior year provision to return adjustments. During fiscal 2021, our effective income tax rate was impacted due to tax benefits from permanent tax credits and prior year provision to return adjustments offset by valuation allowances as well as other various permanent tax adjustments and state taxes. During fiscal 2020, our effective income tax rate was impacted due to a tax benefit of permanent tax credits reduced by a valuation allowance placed on equity investments in proportion to a small pre-tax book loss which results in an abnormal tax rate. The components of the net deferred tax assets were as follows:
| April 30, 2022 |  | May 1, 2021
Deferred tax assets: |  |  |
Accrued warranty obligations | $ | 7,117 |  |  | $ | 6,293 |

The summary of changes in the amounts related to unrecognized uncertain tax benefits are:

Balance at beginning of year | $ | 548 |  |  | $ | 582 |
Gross increases related to prior period tax positions | 17 |  |  | 21 |
Gross decreases related to prior period tax positions | (54) |  |  | (1) |

All of our unrecognized tax benefits would have an impact on the effective tax rate if recognized. It is reasonably possible that the amount of unrecognized tax benefits could change due to one or more of the following events occurring in the next 12 months: expiring statutes, audit activity, tax payments, or competent authority proceedings. A statute of limitations relating to $166 of the unrecognized tax benefits (including interest) expires in the next 12 months. The benefit will be recognized if the statute lapses with no further action taken by regulators. Additionally, we recognized the release of $150 in unrecognized tax benefits related to the lapse of a statute of limitations in fiscal 2022. Interest and penalties incurred associated with uncertain tax positions are included in the "Income tax expense" line item in our consolidated statements of operations. Accrued interest and penalties are included in the related tax liability line item in our consolidated balance sheets of $38 and $38 as of April 30, 2022 and May 1, 2021, respectively. As of April 30, 2022, we had foreign net operating loss (“NOL”) carryforwards of approximately $3,460 primarily related to our operations in Belgium and Ireland, which have indefinite lives. A deferred tax asset has been recorded for all NOL carryforwards totaling approximately $723. However, due to uncertainty in future taxable income, a valuation allowance totaling approximately $581 has been recorded. If sufficient evidence of our ability to generate future taxable income in the jurisdictions in which we currently maintain a valuation allowance causes us to determine that our deferred tax assets are more likely than not realizable, we would release our valuation allowance, which would result in an income tax benefit being recorded in our consolidated statements of operations. Additional tax information: We are subject to U.S. federal income tax as well as income taxes of multiple state and foreign jurisdictions. Fiscal years 2019, 2020 and 2021 remain open to federal tax examinations, and fiscal years 2018, 2019, 2020 and 2021 remain open for state income tax examinations. Certain subsidiaries are also subject to income tax in several foreign jurisdictions which have open tax years varying by jurisdiction beginning in fiscal 2011. In the event of any future tax assessments, we have elected to record the income taxes and any related interest and penalties as income tax expense in our consolidated statement of operations. As of April 30, 2022, we had no deferred tax liability recognized relating to our investment in foreign subsidiaries where the earnings have been indefinitely reinvested. The Tax Act of 2017 generally eliminates U.S. federal income taxes on dividends from foreign subsidiaries, and, as a result, the accumulated undistributed earnings would be subject only to other taxes, such as withholding taxes and state income taxes, on the distribution of such earnings. No additional withholding or income taxes have been provided for any remaining undistributed foreign earnings not subject to the one-time deemed repatriation tax, as it is our intention for these amounts to continue to be indefinitely reinvested in foreign operations in all of our non-U.S. jurisdictions. On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act ("CARES Act") was enacted in response to the COVID-19 global pandemic. The CARES Act includes provisions such as: a deferral of the employer portion of certain payroll taxes, refundable payroll tax credits, alternative minimum tax credit refunds, modifications to the net interest deduction limitations, technical corrections to tax depreciation methods for qualified improvement property, and permitting NOL carryforwards incurred in tax years 2018, 2019, and 2020 (our fiscal years 2019, 2020, and 2021) to be carried back to each of the five preceding taxable years to generate a refund of previously paid income taxes. Subsequently to the CARES Act, the Consolidated Appropriations Act (“CAA”) of 2021 was signed into law on December 27, 2020, expanding and extending rules pertaining to payroll tax credits outlined in the CARES Act. Additionally, the American Rescue Plan Act of 2021 (“ARPA”) was signed into law on March 11, 2021, further extending the payroll tax credits with slight modifications. We continue to evaluate the specific rules, guidance, and procedures allowed by the provisions of the CARES Act, CAA and ARPA. Some of these provisions do not apply to our income tax results; however, we are currently participating in the payment deferral of the employer portion of certain payroll taxes.
