Net operating loss carryforwards, limit description | The United States Tax Reform Act of 1986 contains provisions that may limit the Company's net operating loss carryforwards available to be used in any given year in the event of significant changes in the ownership interests of significant stockholders, as defined. The effect of an ownership change would be the imposition of an annual limitation on the use of NOL carryforwards attributable to periods before the change. The amount of the annual limitation depends upon the value of the Company immediately before the change, changes to the Company's capital during a specified period prior to the change, and the federal published interest rate. |
