During the periods in which the redeemable preferred stock was outstanding, Kronos International, Inc. had a significant amount of net operating loss carryforwards in Germany, the benefit of which had not been recognized under the "more-likely-than-not" recognition criteria of accounting principles generally accepted in the United States of America. Accordingly, the equivalent pre-tax amount for such dividends and accretion would not differ from the amount of such dividends and accretion. (2) The interest expense component of rental expense is calculated as one-third of the aggregate rent expense for each year, which is a reasonable approximation of the interest factor.
