The Company is subject to Internal Revenue Code Section 162(m), which limits the deductibility of compensation paid to certain individuals. It is the Company’s policy to apply the Section 162(m) limitations to stock-based compensation first and then followed by cash compensation. As a result of the vesting of these units and cash compensation paid to date, the Company has disallowed a portion of its compensation paid to the applicable individuals.

The components of the net deferred tax assets (liabilities) at December 31, 2022 and 2021, are as follows:

The Company had a net operating loss carryforward generated as a result of a previous merger amounting to $5,179 and $6,523 as of December 31, 2022 and 2021, respectively. The net operating loss carryforward can be used to offset taxable income in future periods and reduce income tax liabilities in those future periods. While net operating losses are subject to certain annual utilization limits under Section 382, the Company believes the net operating loss carryforwards will be realized based on the projected annual limitation and the length of the net operating loss carryover period. The Company's determination of the realization of the net deferred tax asset is based on its assessment of all available positive and negative evidence. The net operating loss carryforward will begin to expire in 2029.
