This approach requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax bases of assets and liabilities.

The Company is subject to federal income taxes in the United States and the income taxes of multiple state jurisdictions and in Canada.
