Income Taxes

Schedule of reconciliation of expected tax computed at statutory federal income tax rate to provision for income taxes

The Company is subject to taxation in the United States of America (“U.S.”) and files tax returns in the U.S. federal jurisdiction and several state jurisdictions.

​

Through December 31, 2021, the Company incurred net operating losses for federal tax purposes of approximately $76,403 thousand. The Company experienced an “ownership change” within the meaning of Section 382(g) of the Internal Revenue Code in April 2012, subjecting net operating loss carryforwards (incurred prior to the ownership change) to an annual limitation, which may restrict the ability to use those losses to offset taxable income in periods following the ownership change. The Company analyzed the available information to determine the amount of the annual limitation and based on that information estimated the limitation to be $686 thousand annually. The net operating loss carry forwards generated before 2018 may be used to reduce taxable income through the years 2028 to 2037. Net operating loss carryforwards generated for year 2018 and thereafter do not expire.

​

A reconciliation of the expected tax computed at the statutory federal income tax rate to the provision for income taxes is as follows:

​	​	​	​	​	​	​
​		2021			2020
Expected tax benefit at 21%	​	$	(1,657)	​	$	(1,446)
