Components of Net Deferred Income Tax Asset (Liabilities)

The income tax expense for fiscal years 2022 and 2021 primarily reflects withholding tax on rental income earned in foreign jurisdictions. The Company is currently unable to record any tax benefits for its tax losses in the U.S., Canada and the Russian Federation due to the uncertainty surrounding its ability to utilize such losses in the future to offset taxable income.

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. Significant components of the Company’s net deferred income tax assets (liabilities) were as follows (in thousands):
