The Corporation was re-domiciled to the Bahamas in 2015. The substantial portion of our operations are generated out of our executive offices in the Bahamas which has no corporate income taxes. We do have operations subject to income tax in the United States of America, primarily the sale of product out of our New Jersey facilities.

The effect of the re-domiciliation from Canada to the Bahamas resulted in the expiration of several tax attributes relative to our prior operations in Canada including Canadian research tax credit carryforwards and Canadian loss carryforwards. Canadian research tax credit carryforwards and Canadian loss carryforwards expired upon determination of the re-domiciliation by the Canadian federal government amount to $1,686,270 and $55,850,632, respectively.

Nymox recognized no provision (recovery) for federal income taxes for the years ended December 31, 2020, 2019 and 2018.

As of December 31, 2020, 2019 and 2018, deferred tax assets not recognized were as follows:

In Thousands of US Dollars
Description	2020		2019		2018
Tax loss carry forward	$	1,386	$	1,402	$	1,558
Patents capitalized and amortized for tax purposes		0		0		4
Unrecognized deferred tax assets	$	1,386	$	1,402	$	1,568

Deferred tax assets have not been recognized in respect to these items because it is not probable that future taxable profit will be available against which the Corporation can utilize the benefits therefrom. The generation of future taxable profit is dependent on the successful commercialization of the Corporation’s products and technologies.
