The income tax expense for fiscal years 2021 and 2020 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 asset were as follows (in thousands):

Deferred income tax liabilities, net are included as a component of non-current deferred revenue and other liabilities in the accompanying consolidated balance sheets. The 2017 Tax Act was enacted in December 2017. The 2017 Tax Act, among other things, reduces the U.S. federal corporate tax rate from 35% to 21%, effective January 1, 2018, creates new taxes on certain foreign earnings and may require companies to pay a one-time transition tax on undistributed earnings of certain foreign subsidiaries that were previously tax deferred. The Company is not required to pay a one-time transition tax on earnings of our foreign subsidiaries since there were no accumulated earnings on a consolidated basis. The financial reporting basis of investments in foreign subsidiaries exceed their tax basis. A deferred tax liability is not recorded for this temporary difference because the investment is deemed to be permanent. A reversal of the Company’s plans to permanently invest in these foreign operations would cause the excess to become taxable. At September 30, 2021, the Company had $5.2 million of cash and cash equivalents held by its foreign subsidiaries. At September 30, 2021 and 2020, the temporary difference related to undistributed earnings for which no deferred taxes have been provided was approximately $6.5 million and $11.6 million, respectively. Tax return filings which are subject to review by local tax authorities by major jurisdiction are as follows:
| • | United States—fiscal years ended September 30, 2018 through 2021
| • | State of Texas—fiscal years ended September 30, 2018 through 2021
| • | State of New York—fiscal years ended September 30, 2019
| • | State of California – fiscal years ended September 30, 2018 through 2021
| • | State of Pennsylvania – fiscal years ended September 30, 2019
| • | Russian Federation—calendar years 2019 through 2021
| • | Canada—fiscal years ended September 30, 2018 through 2021
| • | United Kingdom—fiscal years ended September 30, 2020 through 2021
| • | Colombia—calendar years 2019 through 2021
The Company had no unrecognized tax liabilities as of September 30, 2021 and 2020. As of September 30, 2021, the Company had net operating loss (“NOL”) carry-forwards of approximately $101.4 million in the United States, $20.2 million in Canada and $1.5 million in Russia which are available to offset future taxable income in those jurisdictions. The NOL carry-forwards for Canada and Russia begin to expire in 2033 and 2026, respectively. The NOL carry-forward for the United States which originated prior to the 2017 Tax Act of $28.3 million begins to expire in 2028. The Company’s NOLs originating after the 2017 Tax Act of $73.1 million do not expire. The Company has not completed a Section 382 limitation study which may prevent it from using its NOLs in the future. Management of the Company has concluded that it is more-likely-than-not that its U.S., Canadian and Russian net deferred tax assets will not be realized in accordance with U.S. GAAP. At September 30, 2021 and 2020, the Company had a valuation allowance against its U.S. net deferred tax assets of $31.6 million and $25.7 million, respectively. At September 30, 2021 and 2020, the Company had a valuation allowance against Canadian net deferred tax assets of $5.4 million, and $5.6 million, respectively. At September 30, 2021 and 2020, the Company had a valuation allowance against its Russian net deferred tax assets of $0.3 million and $0.2 million, respectively.
