5. Income taxes

        Components of the provision for income taxes are as follows:

                                                                                                                                                                                    

        The differences between the actual provision for income taxes and the amounts computed by applying the statutory federal tax rate to income before taxes are as follows:

                                                                                                                                                                                    

        Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Components of deferred tax assets and liabilities as of April 1, 2017 and February 27, 2016, are as follows:

                                                                                                                                                                                    

        The Company has recorded deferred tax assets and liabilities based upon estimates of their realizable value with such estimates based upon likely future tax consequences. In assessing the need for a valuation allowance, the Company considers both positive and negative evidence related to the likelihood of realization of the deferred tax assets. If, based on the weight of available evidence, it is more-likely-than-not that a deferred tax asset will not be realized, the Company records a valuation allowance.

        Prior to the fourth quarter of 2016, the Company maintained a valuation allowance against French deferred tax assets. During fiscal 2016, significant positive evidence provided assurance that the French deferred tax assets will more-likely-than-not be realized. Accordingly, in the fourth quarter of fiscal 2016, the Company released all valuation allowances it had previously maintained against French deferred tax assets. The release resulted in a $100 benefit to the Company's provision for income taxes.

        Foreign and domestic tax credits, net of valuation allowances, totaled approximately $1,490 at April 1, 2017 and approximately $1,661 at February 27, 2016. The various credits available at April 1, 2017 expire in the 2026 tax year.

        The Company had deferred tax assets for foreign and state net operating loss carryovers of $1,955 at April 1, 2017, and approximately $1,888 at February 27, 2016. Valuation allowances of $1,753 and $1,687 were recorded against the net operating loss deferred tax assets at April 1, 2017 and February 27, 2016, respectively.

        The Company is subject to U.S. federal income tax examinations for the year ended March 1, 2014 and forward. The Company is currently under an Internal Revenue Service audit for the tax year ended March 1, 2014.

        The Company accounts for the repatriation of foreign earnings in accordance with ASC 740-30. As such, the Company is partially reinvested based on the guidance provided in ASC 740-30. Undistributed earnings of approximately $33,237 at April 1, 2017 and approximately $33,149 at February 27, 2016, which represents all of the Company's undistributed earnings, have been indefinitely reinvested; therefore, no provision has been made for taxes due upon remittance of those earnings. The increase in undistributed earnings from fiscal 2015 to fiscal 2016 was primarily related to the translation of foreign earnings from Swedish krona to U.S. dollar. Determination of the unrecognized deferred tax liability related to these undistributed earnings is not practicable because of the complexities associated with its hypothetical calculation.

        The Company does not have any uncertain tax positions, according to ASC 740-10, as of April 1, 2017 and February 27, 2016.
