Viskase Companies, Inc. (the “Company”) is unable to file its Annual Report on Form 10-K by April 2, 2007, due to its continuing evaluation of issues regarding the reconciliation of certain of its financial information prepared under French generally accepted accounting principles (“GAAP”) with United States GAAP. The reconciliation relates to accruals of compensation and employee benefit related liabilities with respect to its French subsidiary. The Company has engaged an actuarial firm and is working with its audit firm to measure and appropriately reflect these accruals in its consolidated financial statements. The Company currently intends to file its Form 10-K as soon as practicable and in any event no later than the fifteenth calendar day following the date on which the Form 10-K was due.
