Kaiser Aluminum Restates Previously Reported Financial Data for First Three Quarters of 2005 Resulting in Higher Earnings; Company's Restatement Increases Previously Reported Operating Income by $13.1 Million for First Nine Months of 2005

FOOTHILL RANCH, Calif.--March 30, 2006--Kaiser Aluminum today announced the restatement of operating results for the first nine months of 2005, resulting in a $13.1 million increase in previously reported operating income.

The restatement relates to two items: (1) the company's accounting for payments to two voluntary employee benefit associations (VEBAs) previously established for the benefit of retired hourly and salaried employees and (2) the company's accounting for derivative transactions.

Payments to the VEBAs were previously treated as current operating expenses in the company's financial statements for the first three quarters of 2005. The company concluded that such payments should have been treated as a reduction of pre-petition retiree medical obligations (which are a part of the Liabilities subject to compromise). The effect of the change in accounting for the VEBA payments, as shown more fully below, is to improve operating results by $6.7 million, $5.7 million and $5.7 million in the first, second and third quarters of 2005, respectively.

The change in the company's accounting for derivative contracts relates to the form of the company's documentation in respect of derivatives contracts it enters into to reduce exposures to changes in prices for primary aluminum and energy and in respect of foreign exchange rates. The company determined that its hedging documentation did not meet the strict documentation standards established by Statement of Financial Accounting Standards No. 133 ("SFAS No 133"). As a result, under SFAS No. 133, the company is required to "de-designate" open derivative transactions and reflect fluctuations in the market value of such derivative transactions in its results each period (i.e. mark them to market) rather than deferring the effects until the forecasted transactions (to which the hedges relate) occur. The effect of marking the derivatives to market each quarter rather than deferring gains or losses was to increase Cost of products sold and decrease Operating income by $2.0 million, $1.5 million and $1.0 million in the first, second and third quarters of 2005, respectively.

Management has concluded that, had the company completed its documentation in strict compliance with SFAS No. 133, the derivative transactions would have qualified for "hedge" (i.e. deferral) treatment. The rules provide that, once de-designation has occurred, the company can modify its documentation and re-designate the derivative transactions as "hedges" and, if appropriately documented, re-qualify the transactions for prospectively deferring changes in market fluctuations after such corrections are made. The company is working to modify its documentation and to re-qualify open and post 2005 hedging transactions for treatment as hedges beginning in the second quarter of 2006. However, no assurances can be provided in this regard.

"While the issue with respect to the derivative transactions will create larger fluctuations in the Primary aluminum segment of our business, since our goal is to maintain a balanced metal position, such gains or losses should not be dramatic," said Jack Hockema, President and CEO. "More importantly, the impact of the revised accounting for these transactions does not in any way invalidate the way we are reducing the company's exposure to price and foreign exchange risks and will not have any impacts on the company's strong liquidity and sound financial position upon emergence from Chapter 11."

Kaiser Aluminum (OTCBB: KLUCQ) is a leading producer of fabricated aluminum products for aerospace and high-strength, general engineering, automotive, and custom industrial applications.

(1) Effective December 31, 2005, the Company adopted FIN 47
    retroactive to the beginning of 2005 (See Notes 2 and 4).
    Accordingly, the first three quarters of 2005 have been adjusted
    to (a) recognize a $4.7 charge reflecting the cumulative earnings
    impact of adopting FIN 47 (quarter ended March 31, 2005) and (b)
    an incremental non-cash charge of $ .1 in Cost of products sold
    (quarter ended June 30, 2005) to reflect the accrual of the
    liability recognized at January 1, 2005. The adoption of FIN 47
    also resulted in an increase in Long-term liabilities and
    Accumulated deficit and a decrease in Stockholders' equity of
    $4.7, $4.8 and $4.8 in the first, second and third quarters of
    2005, respectively. There would be no net impact on operating cash
    flows as a result of this change as the decrease in net income
    resulting from the adoption would be offset by the increase in
    liabilities.
