KAISER GROUP HOLDINGS, INC. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.             Basis of Presentation

The accompanying consolidated financial statements of Kaiser Group Holdings, Inc. and subsidiaries (“the Company”), except for the December 31 2005 balance sheet (derived from audited financial statements), are unaudited and have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments considered necessary for a fair presentation have been included.

These statements should be read in conjunction with the Company’s audited consolidated financial statements and footnotes and the other information included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2005. Certain reclassifications have been made to the prior period financial statements to conform them to the presentation used in the March 31, 2006 financial statements.

Kaiser Group Holdings, Inc. (“Kaiser Group Holdings” or the “Company”) is a Delaware corporation that was formed on December 6, 2000 for the purpose of owning all of the outstanding stock of Kaiser Group International, Inc. (“Old Kaiser”), which in turn continues to own the stock of its remaining subsidiaries. On June 9, 2000, Old Kaiser and 38 of its domestic subsidiaries voluntarily filed for protection under Chapter 11 of the United States Bankruptcy Code in the District of Delaware (case nos. 00-2263 to 00-2301). Old Kaiser emerged from bankruptcy with an approved plan of reorganization (which was its Second Amended Plan of Reorganization and is referred to in this report as the “Plan of Reorganization”) that was effective on December 18, 2000 (the “Effective Date”). The Company is deemed a “successor issuer” to Old Kaiser by virtue of Rule 12g-3(a) under the Securities Exchange Act of 1934. A summary of the Plan of Reorganization for Old Kaiser can be found in a Current Report on Form 8-K dated December 5, 2000 filed by Old Kaiser. In this report, unless the context states otherwise, the terms “we”, “our” and “Kaiser” refer to Kaiser Group Holdings (including Old Kaiser as its predecessor) and its subsidiaries.

Currently, apart from resolving remaining bankruptcy claims, the Company has only a limited number of activities, assets and liabilities, primarily consisting of:

·the ownership of a 50% interest in Kaiser-Hill Company, LLC (“Kaiser-Hill”), which serves as the general contractor at the U.S. Department of Energy’s (“DOE”) Rocky Flats site near Denver, Colorado for the performance of a contract for the closure of the site (the “Closure Contract”) (See Notes 4 and 6).

·the closeout and resolution of a completed contract for the engineering and construction of a steel mini-mill in the Czech Republic for Nova Hut (“Nova Hut”) (See Note 6).

·a wholly-owned captive insurance company that has not been issuing new policies since October 1, 2000 and has solely been involved in resolving remaining claims made against previously issued policies. In the fourth quarter of 2004, the Company received regulatory approval and finalized the formation documents of a sponsored captive subsidiary, MS Builders Insurance Company, to enable our wholly-owned captive insurance company to offer derivative captive insurance services to third party clients. As of May 12, 2006, MS Builders Insurance Company has not written any policies.

·an ongoing obligation to fund a capped, post-retirement medical benefit plan for a fixed number of retirees (See Note 6).

·a wholly-owned subsidiary, Kaiser Analytical Management Services, Inc. (“KAMS”), which we formed in April 2004 to take over the operations of the Analytical Services Division of Kaiser-Hill. KAMS provides analytical management services such as sample planning, sample management, records management, performance assessment and data management in the general areas of health and safety, geotechnical, environmental and waste management, and deactivation and decommissioning.

The Company adopted fresh start reporting in its consolidated balance sheet as of December 31, 2000. The American Institute of Certified Public Accountants’ Statement of Position 90-7, “Financial Reporting by Entities in Reorganization Under the Bankruptcy Code” (“SOP 90-7”), requires under certain circumstances resulting from a bankruptcy the creation of a new entity for financial reporting purposes upon the emergence of an entity from bankruptcy. Accordingly, the value of the reorganized enterprise becomes the established amount for the emerging balance of shareholders’ equity, and any accumulated deficit of the predecessor entity is offset against available paid-in-capital, resulting in an emerging retained earnings of zero. Additionally, assets and liabilities are recorded at their fair values.

6

The value of the emerged enterprise used for fresh start reporting as of December 31, 2000 was $87.5 million. It was determined by management with the assistance of independent advisors. The methodology employed involved estimation of the enterprise value taking into consideration a discounted cash flow analysis. The discounted cash flow analysis was based on a seven-year cash flow projection prepared by management, taking into consideration the terminal value of its assets and liabilities as of immediately prior to its emergence from bankruptcy on December 18, 2000. Terminal values of assets and liabilities were determined based either on contracted amounts, actuarial present values and/or management’s estimates of the outcome of certain operating activities. Net after-tax cash flows, assuming a 40% effective tax rate, were discounted at 17% in order to take into consideration the risks and uncertainties inherent in such projections. The cash flow projections were based on estimates and assumptions about circumstances and events that had not yet taken place. Estimates and assumptions regarding individual retained matters which form the collective composition of the overall enterprise value as of December 18, 2000 are inherently subject to significant economic and competitive uncertainties and contingencies beyond the control of the Company. Accordingly, there may be differences between projections and actual results because events and circumstances frequently do not occur as expected and may be significant. More specifically, assumptions within the valuation related to the amount and timing of the ultimate performance and related cash flows of the Company’s investment in Kaiser-Hill have the greatest impact on the overall enterprise valuation.

In May 2005, the Financial Accounting Standards Board (“FASB”) issued Statement of Financial Accounting Standard (“SFAS”) No. 154, “Accounting Changes and Error Corrections — a replacement of APB Opinion No. 20 and FASB Statement No. 3.”  SFAS No. 154 addresses the requirements for the accounting for and reporting of a change in accounting principle. This statement requires retrospective application to prior periods’ financial statements of changes in accounting principle, unless it is impractical to determine period-specific effects or the cumulative effect of the change. We adopted SFAS No. 154 on January 1, 2006. Management does not expect that adoption of SFAS No. 154 will have a material impact on our consolidated financial statements.

2.             General Terms of Plan and Status of Bankruptcy Distributions

The effectiveness of the Plan of Reorganization as of December 18, 2000 did not, in and of itself, complete the bankruptcy process. The process of resolving claims initially filed in the bankruptcy is ongoing.

By far the largest class of claims (“Class 4”) was made up of creditor claims other than trade creditor or equity claims. Class 4 claims included holders of Old Kaiser’s senior subordinated notes due 2003. Holders of Class 4 claims allowed by the bankruptcy court received a combination of cash and Company preferred (“New Preferred”) and common stock (“Kaiser Common Stock”) in respect of their claims. Each Class 4 claimant was entitled to receive one share of New Preferred and one share of Kaiser Common Stock for each $100 of claims, subject to a reduction in the number of shares of New Preferred issued to such claimant by one share for each $55.00 of cash received by the claimant.

Pursuant to the terms of the Plan of Reorganization, the Company was required to complete its initial bankruptcy distribution within 120 days of the Effective Date. Accordingly, to satisfy approximately $136.8 million of allowed Class 4 claims, the Company effected its initial distribution on April 17, 2001. The amount of unresolved Class 4 claims remaining at April 17, 2001 was approximately $130.5 million. To address the remaining unresolved claims, the Bankruptcy Court issued an order on March 27, 2001 establishing an Alternative Dispute Resolution (“ADR”) procedure whereby the remaining claimants and Old Kaiser produced limited supporting data relative to their respective positions and engaged in initial negotiation efforts in an attempt to reach an agreed claim determination. If necessary, the parties were thereafter required to participate in a non-binding mediation before a mediator pre-selected by the Bankruptcy Court. All unresolved claims as of March 27, 2001 are subject to the ADR process. Since April 17, 2001, the date of the initial distribution, $130.0 million of asserted Class 4 claims have been withdrawn, negotiated or mediated to an agreed amount, resulting in cash payments approximating $2.8 million and issuances of 683 shares of New Preferred (all of which have been redeemed) and 823 shares of Kaiser Common Stock. As of March 31, 2006, the aggregate amount of unresolved claims was less than $1.0 million.

The equity class of claims recognized in the Old Kaiser bankruptcy are “Class 5” claims, consisting of holders of Old Kaiser common stock (“Old Common”) and other “Equity Interests” as defined in the Plan of Reorganization. The Plan of Reorganization provides that holders of Equity Interests receive a number of shares of Kaiser Common Stock equal to 17.65% of the number of shares of Kaiser Common Stock issued to allowed Class 4 claimants. In the initial distribution, one share of Kaiser Common Stock was issued for each 96 shares of previously outstanding Old Common. During 2005, the Company settled a significant Class 5 claim asserted by the former shareholders of ICT Spectrum Constructors, Inc. (“ICT Spectrum”), which Old Kaiser had acquired in 1998, and issued an aggregate of 175,003 additional shares of Kaiser Common Stock to such claimants pursuant to the settlement. With the settlement of the ICT Spectrum Class 5 claim and the subsequent issuance of 175,003 shares of Kaiser Common Stock to such claimants, no Class 5 claims remain unresolved at March 31, 2006.

7

As of March 31, 2006, the aggregate amount of unresolved claims was less than $1.0 million. As demonstrated by the claim settlements completed since April 17, 2001, and based on the belief that it is in the best interest of the Company and its current shareholders, the Company has been settling certain remaining Class 4 claims entirely for cash payments in lieu of the combination of cash and New Preferred and Kaiser Common Stock as contemplated in the Plan of Reorganization. The Company intends to continue to use this settlement alternative during the resolution of remaining Class 4 claims. The Company expects to resolve the remaining claims, and to reach a final resolution of issues related to the retiree benefit plans  by the end of 2006 (see Note 6). Upon such final resolution, the Company expects to take the necessary steps to close the bankruptcy cases. Upon such closing, the Bankruptcy Court would no longer be involved in the administration of the Company’s affairs, and the Company’s obligation to pay certain fees and submit periodic reports to the Bankruptcy Court would be terminated. Since closing of the cases requires resolution of all outstanding matters and such resolution is somewhat out of the Company’s control, there is a possibility that the cases will not be closed within the anticipated time period.

In the first quarter of 2004, the Company recorded a $1.4 million liability for future claim settlements based upon the Company’s estimate of unresolved claims at that time. During 2004 and 2005, the Company settled various Class 4 claims reducing approximately $1.0 million of this liability on its balance sheet. Based upon the Company’s estimate of unresolved claims at March 31, 2006, $0.4 million remains in this reserve.

3.Earnings Per Share

Basic earnings per share (“EPS”) is computed by dividing net income by the weighted average number of common shares outstanding for the period. Diluted EPS includes the weighted-average effect of dilutive securities outstanding during the period. Pursuant to the Plan of Reorganization that was effective as of December 18, 2000, all then-outstanding common stock equivalents were cancelled and no common stock equivalents have been issued since that date. As a result, the Company has no dilutive or anti-dilutive securities outstanding.

Share reconciliation:  As disclosed in the Company’s annual report on Form 10-K for the year ended December 31, 2005, since 2001, the Company has been attempting to reconcile the number of shares that were issued by the Company’s transfer agent in the initial distribution in 2001. The Company had not previously recognized the issuance of 11,599 shares of Kaiser Common Stock by the transfer agent. Because the Company has been unsuccessful in disputing the issuance of these shares, during 2005 the Company retroactively restated the number of outstanding shares to reflect the issuance of the 11,599 shares as of June 2001. For purposes of the March 31, 2006 and March 31, 2005 financial statements weighted average shares for basic and diluted earnings per share were 1,789,265 and 1,611,369, respectively.

4.Investments In and Advances To Joint Venture

 Summarized unaudited financial information of Kaiser-Hill was as follows as of March 31 (in thousands):

	2006		2005
Current assets	$	56,594	$	125,529
Non-current assets	—		124,153
Current liabilities	41,975		123,844
Non-current liabilities	—		66,134

	Three Months Ended
	March 31,2006		March 31, 2005
Gross revenue	$	45,841	$	173,371
Net income	—		10,213

On October 13, 2005, Kaiser-Hill declared physical completion of the cleanup and closure of the DOE’s Rocky Flats site. With the certainty of declaration of physical completion, at September 30, 2005, Kaiser-Hill recognized a substantial balance of the remaining performance fee.

On December 8, 2005, the DOE accepted physical completion in accordance with the Closure Contract. The project total fee expected to be earned by Kaiser-Hill pursuant to the Contract is $510.0 million based on Kaiser-Hill’s cost to complete the site closure of $3.44 billion. Through May 12, 2006, Kaiser-Hill has received $509.9 million of such fee from the DOE.

8

Kaiser-Hill now operates under the closure phase of its contract with the DOE, primarily resolving the administrative issues and providing support to the DOE to achieve regulatory closure of the site. The closeout phase of the Contract is a cost reimbursable phase and is not fee bearing, nor does the closeout phase impact fees earned.

Kaiser-Hill recognized a substantial amount of fee income from the DOE upon the declaration of physical completion on October 13, 2005 and, accordingly, the Company’s proportionate share of such income was recorded in Equity Income in Earnings of Affiliate in the Company’s consolidated statement of operations for the year ended December 31, 2005. As a result, upon the receipt of the $80.0 million cash distribution from Kaiser-Hill on March 1, 2006, the Company made a corresponding reduction in its investment in Kaiser-Hill on its balance sheet.

As part of the Company’s adoption of fresh-start reporting as of December 31, 2000, the Company increased the carrying value of the Company’s investment in Kaiser-Hill by $21.1 million, and the Company has been amortizing such increased carrying value over an estimated life of the Kaiser-Hill investment of approximately 6 years. Because Kaiser-Hill declared physical completion of the site on October 13, 2005, at September 30, 2005 the Company wrote off the then remaining $5.3 million unamortized balance as a reduction to the equity income of earnings of affiliate.

On October 13, 2005, Kaiser-Hill declared physical completion of the cleanup and closure of the DOE’s Rocky Flats site. Given the completion of the project in 2005, Kaiser-Hill did not have any fee earnings during the quarter ended March 31, 2006; therefore, there were no associated equity earnings in the Company’s consolidated statement of operations for the quarter ended March 31, 2006.

5.   Mandatorily Redeemable Preferred Stock

On November 17, 2005, the Company redeemed all of the remaining outstanding shares of New Preferred held by non-affiliates. As a result, at December 31, 2005, and March 31, 2006, excluding shares held in in treasury of 101,471, the Company had no shares of New Preferred outstanding. In January 2006, pursuant to approval by the Company’s Board, the treasury shares were cancelled leaving no shares outstanding or in treasury. The Company has reduced the capital in excess of par of $2.7 million that was recorded upon issuance of the preferred shares to affiliates with an associated entry to Retained Earnings.

The Company’s certificate of incorporation authorizes the issuance of 2,000,000 shares of New Preferred. The New Preferred was shown at a liquidation value of $55.00 per share and is a series of authorized preferred stock designated as “Series 1 Redeemable Cumulative Preferred Stock,” and had a par value of $0.01 per share. The New Preferred ranks ahead of Kaiser Common Stock.  The certificate of incorporation of the Company and Delaware law permit the Board of Directors to issue additional series of preferred stock, except that the Board of Directors may not authorize the issuance of any securities that rank senior to or on a parity with the New Preferred, without the consent of holders of at least two-thirds of the New Preferred.  New Preferred was originally issued as settlement for Class 4 claims. As mentioned in Note 2, because the Company has been settling certain remaining Class 4 claims entirely for cash payments in lieu of the combination of cash and New Preferred and Kaiser Common Stock as contemplated in the Plan of Reorganization, the Company has no plans to issue additional shares of New Preferred at March 31, 2006.

The Company adopted FAS 150, “Accounting for Certain Financial Instruments with Characteristics of both Liabilities and Equity,” effective July 1, 2003. Due to the mandatorily redeemable feature of the New Preferred, the New Preferred was reclassified from mezzanine equity to a long term liability on the consolidated balance sheet, and the preferred stock dividends were reclassified to interest expense on the consolidated statement of operations effective July 1, 2003. There was no transition adjustment recognized upon adoption of FAS 150.

Cumulative dividends, classified as interest expense subsequent to July 1, 2003, on the New Preferred were payable on a quarterly basis, as of April 30, July 31, October 31 and January 31, either in cash at an annual rate of 7% of the liquidation preference per share or in additional shares of New Preferred at an annual rate of 12% of the per share liquidation preference. Dividends accrued on the New Preferred commencing with the initial distribution date, April 17, 2001. Dividends were not paid to any affiliate of the Company on account of that affiliate’s ownership of shares of preferred stock as long as there was New Preferred shares held by any non-affiliated entities or parties. Upon the November 17, 2005 redemption of the 207,431 shares of remaining outstanding New Preferred held by non-affiliates, the Company no longer has a dividend payment requirement.

6.Other Contingencies

The Company has various obligations and liabilities from its operations, including general overhead expenses in connection with maintaining, operating and winding down the various entities and net assets comprising the Company. Additionally, the Company believes contingent liabilities may exist in the following areas:

Nova Hut

Although Old Kaiser sold its Metals Mining and Industry business unit in August 2000, it retained its Netherlands subsidiary, Kaiser Netherlands, B.V., which had been responsible for a turnkey engineering and construction services contract for the construction of a steel mini-mill in the Czech Republic for Nova Hut. After construction of the mini-mill was complete in 2000, the contract with Nova Hut provided for a maximum of three possible performance tests. The first performance test was completed on November 13, 2000. Kaiser Netherlands believes that the first performance test was successful and that Nova Hut should have agreed to final acceptance of the mini-mill and made final payment of amounts accrued by Kaiser Netherlands throughout the project, including fee and retention amounts with release of performance guarantee instruments. Nova Hut, however, asserted that the first test was not successful. Kaiser Netherlands believes that such contention may have been put forth in response to severe financial constraints on Nova Hut’s operations resulting from weakening conditions in the worldwide steel market and the significant amounts that Kaiser Netherlands believed it was contractually due. As of March 31, 2006, this dispute has not been resolved, and Kaiser Netherlands continues to pursue legal action to enforce its rights. Until recently, the primary legal venue of this dispute has been the Delaware bankruptcy proceeding for Old Kaiser, where the Company has asserted claims against Nova Hut and the International Finance Corporation (“IFC”). The Delaware bankruptcy court had previously ruled that the Company, as opposed to Kaiser Netherlands, could proceed with prosecution of its specific claims against Nova Hut and IFC in the Delaware bankruptcy court venue. Both Nova Hut and IFC appealed this ruling and, during the first quarter 2004, the Delaware bankruptcy court’s decision regarding the IFC was overturned by the District Court, ruling that the IFC enjoys sovereign immunity from prosecution. Kaiser Holdings filed an appeal with the U.S. Court of Appeals for the Third Circuit regarding this decision in favor of the IFC and, on February 25, 2005, the Third Circuit overturned the District Court’s decision. The IFC’s request for a rehearing of the case by the Third Circuit was refused. The IFC then petitioned the Delaware bankruptcy court to stay proceedings pending completion of the Kaiser Netherlands-Nova Hut arbitration proceeding discussed below. This IFC motion was granted. With regard to the Nova Hut appeal, the District Court has ruled that U.S. bankruptcy proceedings should also be stayed pending completion of arbitration proceedings.

In January 2004, Kaiser Netherlands filed arbitration claims against Nova Hut in the amount of $51.1 million with the International Chamber of Commerce (“ICC”). In November 2004, Kaiser Netherlands’ claim against Nova Hut was amended to include late interest and other charges and now totals $67.5 million. The arbitration panel has been constituted, and a hearing was held in September 2005. At present, we expect a decision to be issued before the end of the second quarter of 2006. Nova Hut has submitted a $49.7 million counterclaim against Kaiser Netherlands in these same ICC proceedings. At this time, the Company is unable to predict the outcome of the arbitration. The Company intends to vigorously defend the claims.

In December 2003, the ICC, under the dispute resolution provisions of the Nova Hut mini-mill subcontract between Kaiser Netherlands and the mini-mill’s main equipment supplier, Tippins, Inc., issued a final award that was on balance favorable to Kaiser Netherlands. As a result of the ruling, Kaiser Netherlands was relieved of the obligation to pay additional retention to Tippins, and Kaiser Netherlands was awarded a net cash settlement of $2.6 million. The Company has not recorded this award due to the uncertainties regarding collectibility. However, the Company intends to vigorously pursue collection of this award.

The continued litigation of these disputes has had, and will continue to have, a negative impact on the cash flow of Kaiser Netherlands and Kaiser Holdings.

The components of “Contract receivable, net” consist entirely of the carrying value of the net assets of the Nova Hut project. Based on the Company’s continued concern over Nova Hut’s financial difficulties and the lack of a settlement resulting from an earlier bankruptcy court-sponsored mediation in the fourth quarter of 2003, the Company further reduced the carrying value of the remaining Nova Hut contract receivable from $6.0 million to $3.0 million by recording an additional reserve of $3.0 million, net of a $1.1 million income tax benefit, through a charge to “Loss from Discontinued Operations”. This reserve is in addition to a reserve recorded in 2001, which reduced the carrying value of the Nova Hut contract receivable from $21.6 million to $6.0 million by recording a reserve of approximately $9.8 million, net of a $5.8 million income tax benefit, through a charge to “Loss from Discontinued Operations.”  These adjustments to the contract receivable carrying value were determined based on the Company’s late 2003 estimate of Nova Hut’s ability to pay such liability.

Kaiser-Hill

On October 13, 2005, Kaiser-Hill declared physical completion of the cleanup and closure of the DOE’s Rocky Flats site. DOE has reviewed Kaiser-Hill’s declaration as required under the Closure Contract. On December 8, 2005, the DOE accepted the physical completion declaration in accordance with the Closure Contract. The projected total fee to be earned pursuant to the Closure Contract is expected to be $510.0 million based on Kaiser-Hill’s cost to complete the site closure of $3.44 billion. As of March 31, 2006, Kaiser-Hill has received $505.0 million, and as of  May 12, 2006, Kaiser-Hill has received $509.9 million of such fee from the DOE. A substantial portion of the received fee remains subject to audit.

Under Kaiser-Hill’s contract with the DOE, Kaiser-Hill is not responsible for, and the DOE pays all costs associated with, any liability, including, without limitation, any claims involving strict or absolute liability and any civil fine or penalty, expense, or remediation cost, but limited to those of a civil nature, which may be incurred by, imposed on, or asserted against Kaiser-Hill arising out of any act or failure to act, condition, or exposure which occurred before Kaiser-Hill assumed responsibility on July 1, 1995 (pre-existing conditions). To the extent the acts or omissions of Kaiser-Hill constitute willful misconduct, lack of good faith, or failure to exercise prudent business judgment on the part of Kaiser-Hill’s managerial personnel and cause or add to any liability, expense, or remediation cost resulting from pre-existing conditions, Kaiser-Hill is responsible, but only for the incremental liability, expense, or remediation caused by Kaiser-Hill.

The Closure Contract further provides that Kaiser-Hill will be reimbursed for the reasonable cost of bonds and insurance allocable to the Rocky Flats contract and for liabilities and expenses incidental to these liabilities, including litigation costs, to third parties not compensated by insurance or otherwise. There is an exception to this reimbursement provision applicable to liabilities caused by the willful misconduct, lack of good faith or failure to exercise prudent business judgment by Kaiser-Hill’s managerial personnel.

As the contract between Kaiser-Hill and the DOE is cost-reimbursable in nature, the costs invoiced by Kaiser-Hill for reimbursement by the DOE are subject to audit by the U.S. government. Also since the inception of Kaiser-Hill, the Company invoiced certain management oversight costs to Kaiser-Hill. Government audits at Kaiser-Hill are ongoing. Although Kaiser-Hill and the Company have historically provided for their estimates of disallowed costs on cost-reimbursable contracts, uncertainties exist with regard to whether government audits will result in any disallowed costs needing to be refunded to the government customer. The continued adequacy of provisions for reserves with regard to unallowable costs is reviewed regularly.

Kaiser-Hill now operates under the closeout phase of the DOE Rocky Flats Closure Contract, primarily resolving open administrative issues and providing support to the DOE to achieve regulatory closure of the site. The closeout phase of the Contract is a cost reimbursable phase and is not fee bearing, nor does the closeout phase impact fees earned.

On December 8, 2005, when the DOE accepted physical completion in accordance with the Rocky Flats contract, it authorized Kaiser-Hill to invoice all remaining performance fees less a retained amount equaling $5.0 million which was retained by the DOE for possible contract contingencies. On January 11, 2006, Kaiser-Hill received payment for all fees except for the retained amount. As a result of this payment, on March 1, 2006, the Company received an $80.0 million cash distribution (representing its 50% share) from Kaiser—Hill. On April 14, 2006, $4.9 million of the remaining $5.0 million retention was released by the DOE. It can not be determined at this time what proportion of the remaining $0.1 million DOE retention balance will ultimately be released and when (if ever) such a release would occur.

In addition to the $4.9 million retention amount released by the DOE on April 14, 2006, Kaiser-Hill has withheld $17.3 million in cash from distribution until administrative issues associated with certain Kaiser-Hill employee pension and post-retirement benefits, as well as further administrative contract closeout issues, are clarified with the DOE. The Company expects to receive its 50% share of any subsequent distributions of such funds by Kaiser-Hill. As of May 12, 2006, Kaiser-Hill had received $509.9 million of the $510.0 million due from the DOE.

Post-Retirement Benefit Plan Obligation

In accordance with the terms and provisions of the Second Amended Plan of Reorganization for Old Kaiser, the Company remains obligated to continue to fulfill the provisions of Old Kaiser’s previously curtailed benefits plan, which provides certain medical and death benefits to a group of retirees. All of the benefit derived from the plan is fully covered by the Company’s self-insurance. With respect to the retirees covered by the medical and death self-insured plan, the benefits are funded to a claims administrator as participants’ insurance claims are reimbursed.

11

No new participants can be added to the plan. The net present value benefit obligation, as of March 31, 2006, was $6.8 million. This amount will continue to decrease as the population of covered participants declines for the purposes of medical benefits and as death benefits are paid out.

Since the December 2000 approval of the reorganization plan, the Company has been negotiating with the Delaware Bankruptcy Court-appointed Official Committee of Retirees (“OCR”) to design and implement a benefits funding plan that would provide for all retiree benefit obligations going forward.  In an adversary claim hearing in the Delaware Bankruptcy Court held on April 12, 2006, the Court accepted the Company’s proposal to establish a Voluntary Employees’ Beneficiary Association (“VEBA”) to fund retirees’ future medical and death benefits in the present value amount of approximately $6.1 million. The present value pension obligation of $0.3 million will continue to be funded directly by the Company. In addition, in accordance with the Delaware Bankruptcy Court ruling, the Company will establish a declining balance escrow account to fund expected additional future VEBA administrative costs in the event the Company decides to terminate its operations at some future date. The initial escrow fund amount will be $0.6 million and this amount will be reduced by $25,000 for each year that the Company remains in business. As of March 31, 2006, the Company had an accrued liability of $6.8 million relating to this matter. Upon final establishment of the VEBA, such liability will be adjusted to the net present value.

Furthermore, according to the terms of the Delaware Bankruptcy Court decision, after the VEBA has been in place for five years, the Company will be required to undertake an actuarial analysis of the projected net present value of benefits remaining to be paid out. If the remaining VEBA fund amount is then not sufficient to pay the estimated present value of future benefits obligations, then the Company will be required to contribute the estimated shortfall amount to the VEBA fund. It is not possible to predict at this time whether a shortfall in the VEBA fund would exist after a period of five years and, if so, what the Company’s contribution requirement for a shortfall amount would be in this circumstance.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

General Overview

Since the Plan of Reorganization of Old Kaiser under Chapter 11 of the Bankruptcy Code became effective on December 18, 2000, we have completed the initial bankruptcy distributions to allowed claimholders, continued to progress in resolving remaining outstanding bankruptcy claims, managed our remaining assets, wound down unnecessary elements of previous activities and corporate structure, redeemed all of the New Preferred shares outstanding and formed two new business opportunities, KAMS and MS Builders Insurance Company.

Following the effectiveness of the Plan of Reorganization, we now have only a limited number of activities, assets and liabilities, primarily consisting of the following:

·We own Kaiser-Hill equally with CH2M Hill. Kaiser-Hill has been our major source of income. Kaiser-Hill served as the general contractor at the DOE’s Rocky Flats site. Kaiser-Hill has performed for the Department of Energy at this site since 1995 and in January 2000 was awarded a new contract to manage the closure of the site. The level of success experienced by Kaiser-Hill in achieving timely closure of the Rocky Flats site, and the cost of achieving such closure, have been and continue to be the primary determinants of our long-term financial performance following the completion of the bankruptcy reorganization process.

·We have a substantial claim, pending resolution, against the owner of a steel mini-mill that we constructed for Nova Hut in the Czech Republic. The engineering and construction of the mini-mill was completed in 2000 by our subsidiary, Kaiser Netherlands.

·We own a captive insurance company that has not been issuing new policies since October 1, 2000 and has solely been involved in resolving remaining claims made against previously issued policies. In the fourth quarter of 2004, we received regulatory approval and finalized the formation documents of a sponsored captive subsidiary, MS Builders Insurance Company, to enable our wholly-owned captive insurance company to offer derivative captive insurance services to third party clients. As of May 12, 2006, MS Builders Insurance Company has not written any policies.

·We have an ongoing obligation to fund a capped post-employment medical benefit plan for a fixed group of retirees.

12

·We formed KAMS in April 2004 to take over the operations of the Analytical Services Division of Kaiser-Hill. KAMS provides analytical management services such as sample planning, sample management, records management, performance assessment and data management in the general areas of health and safety, geotechnical, environmental and waste management, and deactivation and decommissioning.

Outlook

Potential Kaiser-Hill Distributions and the Nova Hut Disputes. As we look forward, by far the most significant factor in determining the value of our common stock is the closeout performance of Kaiser-Hill and the completion of the U.S. Government’s related project audits. Another material uncertainty potentially affecting our future results is the outcome of the disputes we have in arbitration with Nova Hut.

On October 13, 2005, Kaiser-Hill declared physical completion of the clean up and closure of the DOE’s Rocky Flats site. On December 8, 2005 the DOE accepted the physical completion in accordance with the contract. The projected total fee to be earned pursuant to the contract is estimated to be $510.0 million based on Kaiser-Hill’s cost to complete the site closure of $3.44 billion.

Kaiser-Hill recognized a substantial amount of fee income from the DOE upon the declaration of physical completion on October 13, 2005 and accordingly, the Company’s proportionate share of such income was recorded in Equity Income in Earnings of Affiliate in the consolidated statement of operations for the year ended December 31, 2005. As a result, upon the receipt of the $80.0 million cash distribution from Kaiser-Hill on March 1, 2006, the Company made a corresponding reduction in its investment in Kaiser-Hill on its balance sheet.

Kaiser-Hill now operates under the closeout phase of its contract with the DOE, primarily resolving open administrative issues and providing support to the DOE to achieve regulatory closure of the site. The closeout phase of the contract is a cost reimbursable phase and is not fee bearing nor does the closeout phase impact fees earned.

On December 8, 2005, when the DOE accepted physical completion in accordance with the Rocky Flats contract, it authorized Kaiser-Hill to invoice all remaining performance fees less a retained amount equaling $5.0 million which was retained by the DOE for possible contract contingencies. On January 11, 2006, Kaiser-Hill received payment for all fees except for the retained amount. As a result of this payment, on March 1, 2006, the Company received an $80.0 million cash distribution (representing its 50% share) from Kaiser-Hill. As of March 31, 2006, Kaiser-Hill had received $505.0 million of the $510.0 million due from the DOE. On April 14, 2006, $4.9 million of the remaining $5.0 million was released by the DOE. It can not be determined at this time what amount, if any, of the remaining $0.1 million DOE retention balance will ultimately be released and when, if ever, such a release will occur.

Kaiser-Hill has not distributed the $4.9 million received from the DOE on April 14, 2006. In addition, Kaiser-Hill has withheld $17.3 million in cash from distribution until administrative issues associated with certain Kaiser-Hill employee pension and post-retirement benefits, as well as further administrative contract closeout issues, are clarified with the DOE. The Company expects to receive its 50% share of any distributions of such funds by Kaiser-Hill. As of May 12, 2006, Kaiser-Hill had received $509.9 million of the $510.0 million due from the DOE.

Nova Hut. As discussed elsewhere, we have pending against Nova Hut an arbitration before the International Chamber of Commerce (“ICC”) with respect to a contract we completed for the engineering and construction of a steel mini-mill in the Czech Republic. Our aggregate claims are for $67.5 million, and Nova Hut has asserted counterclaims of $49.7 million. At this time, the Company is unable to predict the outcome of the arbitration. The Company intends to vigorously defend the claims.  At present, we do not expect that the ICC will issue a decision until the second quarter of 2006.

Proposed Reverse Split.Our Kaiser Common Stock is currently registered under the Securities Exchange Act of 1934 (the “Exchange Act”), and consequently we are subject to reporting obligations of the Exchange Act. In special meetings on March 31, 2005 and June 20, 2005, our Board unanimously approved a 1-for-20 reverse split of the Kaiser Common Stock. The Company, in conjunction with its Board, is reassessing the issues surrounding a possible reverse split and deregistration of the Company. Proceeding with the reverse split would require that we amend the Company’s Certificate of Incorporation, which requires stockholder approval. If we do proceed, we would intend to submit any such proposal to our stockholders for decision at the next Annual Meeting of Stockholders. It is anticipated that such a reverse split would reduce the number of record holders of Kaiser Common Stock to below 300, which would allow us to terminate our reporting obligations under the Exchange Act and continue operations as a non-reporting company. In that event, we would file a Form 15 with the Securities and Exchange Commission (“Commission”). Upon filing of the Form 15, our reporting obligations under the Exchange Act would be suspended, meaning that we would no longer be required to file with the Commission certain reports and forms, including Forms 10-K, 10-Q and 8-K and proxy statements. In such event, thereafter, the Company would provide information about its quarterly and annual financial results to its remaining stockholders by other means, such as through its web site and in press releases.

Critical Accounting Policies and Significant Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires that we make estimates and assumptions affecting the assets and liabilities (including contingent assets and liabilities) reported at the date of the Consolidated Financial Statements and the income statement amounts reported for the periods presented. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. Actual results may differ from these estimates under different assumptions or conditions.

Our accounting measurements that are most affected by our estimates of future events are:

·Recoverability of accounts receivable, a contract receivable, and investments.

·Income tax provision, deferred tax assets and liabilities.

·Use of the equity method of accounting for Kaiser-Hill, an affiliate that we have the ability to significantly influence but not control. In accordance with the equity method of accounting, we record our proportionate share of the affiliate’s income or losses.

·Estimated fees on the Kaiser-Hill joint venture. Estimating future costs, contract contingencies and revenues and profits is a process requiring a high degree of judgment. In the event of a change in total estimated contract cost or profit, the cumulative effect of such change is recorded in the period the change in estimate occurs. Now that the contract has been declared complete, additional revenue recognition and our profitability from the Kaiser-Hill contract may be adversely affected to the extent that estimated cost to complete or incentive or award fee estimates are revised upon audit from the U. S. Government. The Kaiser-Hill contract contains incentive provisions for increased or decreased revenue and profit based on actual performance against established cost targets and schedule-related goals. Incentive fees have been included in estimated contract revenue at the time the amounts can be reasonably determined and are reasonably assured based on historical experience and other objective criteria. Should total costs of the project be revised based upon the results of U. S. Government audits, previously recognized revenues could be reversed and/or future period revenues could be reduced.

·Our liability in connection with a post-employment medical benefit plan for a fixed group of retirees. This liability is affected by changes in the discount rate, medical cost trend rates and certain actuarial assumptions. Should actual rates and results differ from the assumptions used, revisions to the liability would be required resulting in additional income statement charges.

New Accounting Standards

In May 2005, the Financial Accounting Standards Board (“FASB”) issued Statement of Financial Accounting Standard (“SFAS”) No. 154, “Accounting Changes and Error Corrections — a replacement of APB Opinion No. 20 and FASB Statement No. 3.”  SFAS No. 154 addresses the requirements for the accounting for, and reporting of, a change in accounting principle. This statement requires retrospective application to prior periods’ financial statements of changes in accounting principle, unless it is impractical to determine period-specific effects or the cumulative effect of the change. We adopted SFAS No. 154 effective January 1, 2006. Management does not expect that adoption of SFAS No. 154 will have a material impact on our consolidated financial statements.

RESULTS OF OPERATIONS

Equity Income In Earnings of Affiliate

Our current major remaining source of income is a 50% ownership in Kaiser-Hill. We own Kaiser-Hill equally with CH2M Hill. The financial information contained herein for Kaiser-Hill is reflected on the equity basis.

 Contract Provisions for Revenue and Performance Award

Kaiser-Hill’s contract with the DOE provides that Kaiser-Hill earn revenue equal to the actual cost of physical completion plus a performance fee. The performance fee is determined based on (1) Kaiser-Hill’s cost to complete the site closure, which must be within the range of $3.1 billion and $4.9 billion, (2) the schedule of physical completion, which must be before 2007 and (3) Kaiser-Hill’s safety performance. On October 13, 2005, Kaiser-Hill declared physical completion of the cleanup and closure of the DOE’s Rocky Flats site. At the time of declaration of physical completion on October 13, 2005, Kaiser-Hill’s cost estimate to complete the project remained at $3.44 billion, which resulted in a performance fee payable to Kaiser-Hill projected to be $510.0 million, of which $255.0 million had previously been received. On December 8, 2005, the DOE affirmed Kaiser-Hill’s declaration as required under the contract and the DOE authorized Kaiser-Hill to invoice all remaining performance fees less a retained amount equaling $5.0 million. On January 11, 2006, Kaiser-Hill received payment for all remaining fees except the retained amount. On April 14, 2006, Kaiser-Hill received payment of $4.9 million from the $5.0 million withheld amount.

14

Since Kaiser-Hill declared physical completion, many of the performance risks have been eliminated, but contract risks and uncertainties remain. As a result of declaration of physical completion in October 2005, Kaiser-Hill recognized all remaining performance fees under the contract in 2005 and has established reserves for certain risks and uncertainties related to the contract (see details described below in “Closure Contract Billing Provisions”). Kaiser-Hill will reverse these reserves to the extent it is successful in mitigating or eliminating these remaining contract risks and uncertainties.

For the three months ended March 31, 2006, we reported no income from our 50% ownership in Kaiser-Hill because during 2005, Kaiser-Hill recorded all of the contract fee income, less applicable reserves, due from the DOE. In the future, we may have additional income from Kaiser-Hill to report to the extent Kaiser-Hill releases certain retained reserve amounts, as mentioned above. For the three months ended March 31, 2005, we recorded our 50% equity in Kaiser-Hill’s income, recognizing income of $4.2 million net of $0.9 million of amortization of the excess carrying value of our investment in Kaiser-Hill over our ownership percentage of the underlying Kaiser-Hill equity.

Closure Contract Billing Provisions

From the inception of Kaiser-Hill’s contract with the DOE in February 2000 through March 31, 2006, Kaiser-Hill invoiced the DOE for the performance fee based on the contract provisions of approximately $510.0 million, and collected an aggregate of $505.0 million in fees from the DOE.

Fee payments made by the DOE to Kaiser-Hill, less certain non-reimbursable costs and reserve and retention amounts, have been distributed to the joint venture owners upon receipt. Kaiser-Hill has historically incurred expenses that are not reimbursable by the DOE pursuant to applicable Federal regulations. Accordingly, such expenses, which Kaiser-Hill estimates could total up to 15% to 20% of the total award fee, are deducted from the total fee earned and collected by Kaiser-Hill prior to any distributions to either of its two owners. From Kaiser-Hill’s inception through March 31, 2006, Kaiser-Hill has distributed $187.7 million in cash to each of its two owners. The Company may receive further distributions in the future as described below.

On April 14, 2006, Kaiser-Hill received from the DOE an additional $4.9 million of the $5.0 million fee amount which was withheld from the January 2006 fee payment for possible contract contingencies. It is not known when, if ever, the remaining DOE retention balance of $0.1 million will be released to Kaiser-Hill. By contract, this remaining retention balance amount can not be released until final contract closeout. We expect to receive our 50% share of any distributions made by Kaiser-Hill of released DOE retention amounts.

Of the fees received from the DOE, Kaiser-Hill has, in addition to the $4.9 million received on April 14, 2006, withheld $17.3 million in cash from distribution to each of its two owners until administrative issues associated with certain Kaiser-Hill employee pension and post-retirement benefits, as well as further administrative contract closeout issues, are clarified with the DOE. We expect to receive our 50% share of any distribution of these withheld funds from Kaiser-Hill.

Kaiser-Hill recognized a substantial amount of the fee income from the DOE upon the declaration of physical completion on October 13, 2005 and, accordingly, the Company’s proportionate share of such income was recorded in Equity Income in Earnings of Affiliate in its consolidated statement of operations for the year ended December 31, 2005. As a result, upon the receipt of the $80.0 million distribution from Kaiser-Hill on March 1, 2006, the Company made a corresponding reduction in its investment in Kaiser-Hill on its balance sheet.

Kaiser-Hill now operates under the closeout phase of its contract with the DOE, primarily resolving open administrative issues and providing support to the DOE to achieve regulatory closure of the site. The closeout phase of the contract is a cost reimbursable phase and is not fee bearing nor does the closeout phase impact fees earned. Effective December 31, 2005, Kaiser-Hill terminated its remaining employees. Staff necessary to complete closeout activities is expected to be subcontracted or provided by CH2M Hill.

15

For the three months ended March 31, 2006, we reported no income from our 50% ownership in Kaiser-Hill because during 2005, Kaiser-Hill recorded all of the contract fee income, less applicable reserves, due from the DOE. In the future, we may have additional income from Kaiser-Hill to report to the extent Kaiser-Hill determines that certain recorded reserves, as mentioned above, are no longer necessary. For the three months ended March 31, 2005, we recorded our 50% equity in Kaiser-Hill’s income, recognizing income of $4.2 million net of $0.9 million of amortization of the excess carrying value of our investment in Kaiser-Hill over our ownership percentage of the underlying Kaiser-Hill equity. As part of our adoption of fresh-start reporting as of December 31, 2000, we increased the carrying value of our investment in Kaiser-Hill by $21.1 million, and we were amortizing that difference over an estimated life of the Kaiser-Hill investment of approximately 6 years. At March 31, 2005, $6.1 million of the difference remained unamortized. Upon Kaiser-Hill’s declaration of physical completion on October 13, 2005, we wrote off at September 30, 2005, the then remaining $5.3 million unamortized balance.

Administrative Expenses

Administrative expenses for the three months ended March 31, 2006 were $1.4 million, an increase of $0.2 million compared to the three months ended March 31, 2005, which is due primarily to an increase in legal fees in connection with the negotiating and claims resolution activities in Delaware Bankruptcy Court associated with the Company’s attempt to resolve the post-retirement benefit plan obligations claim.

Our cost to provide certain on-going post-retirement medicalbenefits to a fixed number of retirees is also treated as an administrative expense. In the three month periods ended March 31, 2006 and 2005, the expenses related to this plan were $0.3 million and $0.2 million, respectively.

 Interest Income

Interest income for the three months ended March 31, 2006 was $0.2 million, which represents a nominal change compared to the three months ended March 31, 2005.

Interest Expense

As a result of the adoption of Statement of Financial Accounting Standards No. 150, “Accounting for Certain Financial Instruments with Characteristics of both Liabilities and Equity” (“SFAS No. 150”), effective July 1, 2003, and the classification of the Series 1 Redeemable Cumulative Preferred Stock (“New Preferred”) as a liability, preferred stock dividends are reflected as interest expense. We incurred no interest expense for the three months ended March 31, 2006 compared to interest expense for the three month period ended March 31, 2005 of $0.5 million. The decrease in interest expense is due to redemption of all outstanding preferred stock in the fourth quarter of 2005.

Income Tax Expense

We recorded an income tax benefit of $0.8million on operating loss from continuing operations of $1.3 million during the three months ended March 31, 2006. Our effective income tax rate of 59% for the three months ended March 31, 2006, primarily reflects the non-taxability of certain income for federal income tax purposes. For the three months ended March 31, 2005, we recorded an income tax expense of $1.3 million on operating income from continuing operations of $3.0 million. Our effective tax rate of 44% for the three months ended March 31, 2005 reflects the non-deductibility of certain expenditures for federal income tax purposes.

LIQUIDITY AND CAPITAL RESOURCES

Operating Activities

We used $29.0 million of cash during the three months ended March 31, 2006 compared to $2.9 million for the three months ended March 31, 2005. The $26.1 million increase in the use of cash for the three months ended March 31, 2006, compared to the three months ended March 31, 2005, was primarily due to an increase in income tax payments made in 2006 compared to 2005.

16

Investing Activities

We received $80.0 million in distributions from Kaiser-Hill during the three months ended March 31, 2006 compared to $10.5 million for the three months ended March 31, 2005. The increase of Kaiser-Hill cash distributions is a result of the DOE’s acceptance of physical completion in accordance with the Rocky Flats Contract and the receipt by Kaiser-Hill of all project fees except for the DOE retention amount of $5.0 million.

Financing Activities

During the three months ended March 31, 2006, there were no financing activities to report. For the three months ended March 31, 2005, we transferred $32,000 into restricted cash to use for future settlement of Class 4 claims.

Liquidity and Capital Resource Outlook

We currently have no debt. We continue to finance the bankruptcy distribution requirements and follow-on working capital needs in part through the use of the available cash and distributions from Kaiser-Hill. Based on (i) current expectations for operating activities and results, (ii) expected Kaiser-Hill distributions, (iii) our current available cash position, (iv) recent trends and projections in liquidity and capital needs, (v) current expectations of total allowed claims upon the completion of the bankruptcy proceedings, and (vi) estimate of amounts necessary to satisfy our obligation to provide future benefits to a fixed group of retirees, management believes we have sufficient liquidity to cover our future operating needs and income tax requirements. With the retirement of the remaining outstanding New Preferred on November 17, 2005, we no longer have future interest payment requirements on preferred stock.

Other Matters

We have various obligations and liabilities from our continuing operations, including general overhead expenses in connection with maintaining, operating and winding down the various entities. Additionally, we believe contingent liabilities may exist in the areas described in Note 6 to the Consolidated Financial Statements.

ITEM 3.  QUANTITATIVE AND QUALITATIVE INFORMATION ABOUT MARKET RISK

We do not believe that we have significant exposures to market risk because we do not presently have any debt. The interest rate risk associated with our obligation to fund a capped retiree medical obligation is not sensitive to interest rate risk other than with respect to the determination of the present value of our remaining obligation thereunder. A 10% increase or decrease in the average annual prime rate would result in a decrease in the carrying value of the plan obligation but would not change the actual cost of the plan.

ITEM 4. CONTROLS AND PROCEDURES

As of March 31, 2006, an evaluation was performed under the supervision and with the participation of the Company’s management, including the Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of the Company’s disclosure controls and procedures (as defined in Rule 13a-15(e) or 15d-15(e) under the Exchange Act). Based on that evaluation, the Company’s management, including the Chief Executive Officer and Chief Financial Officer, concluded that the Company’s disclosure controls and procedures were effective as of March 31, 2006. There were no significant changes in the Company’s internal control over financial reporting (as defined in Rule 13a-15(f) or 15d-15(f) ) that occurred during the period covered by this report that have materially affected, or that are reasonably likely to materially affect, our internal control over financial reporting.

Item 1A. Risk Factors

RISK FACTORS RELATING TO KAISER HOLDINGS AND FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q contains, and our other periodic filings with the Securities and Exchange Commission and written or oral statements made by our officers and directors to the press, potential investors, securities analysts and others, may contain forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. These forward-looking statements are not historical facts, but rather are predictions, and generally can be identified by use of statements that include terms such as “believe,” “expect,” “anticipate,” “estimate,” “intend,” “plan” or “foresee” or other words or phrases of similar import. Similarly, statements that describe or contain information related to matters such as our intent, belief, or expectation with respect to financial performance, claims resolution, cash availability, stock redemption plans, contract awards and performance, potential acquisitions and joint venturesand cost-cutting measures are forward-looking statements. These forward-looking statements often reflect a number of assumptions and involve known and unknown risks, uncertainties and other factors that could cause our actual results to differ materially from those currently anticipated in these forward-looking statements. In light of these risks and uncertainties, including those described below, the forward-looking events might or might not occur. We undertake no obligation to publicly update any forward-looking statement, whether as a result of new information, future events or otherwise.

Our remaining primary source of funding is distributions from Kaiser-Hill and possible recovery of our claim against Nova Hut, which are subject to uncertainties that may adversely impact the potential value of our common stock.

There are risks associated with the resolution of administrative issues surrounding certain Kaiser-Hill employee pension and post-retirement benefits, along with additional administrative contract closeout issues, that may affect the timing and award of future cash distributions  from Kaiser-Hill to the Company.

On October 13, 2005, Kaiser-Hill declared physical completion of the cleanup and closure of the DOE’s Rocky Flats site. As a result, on January 11, 2006, Kaiser-Hill received payment from the DOE for all remaining performance fees, less a retained amount equaling $5.0 million, which was retained by the DOE for possible contract contingencies. On April 14, 2006, the DOE released $4.9 million of the $5.0 million retention amount to Kaiser-Hill. Kaiser-Hill has further withheld $17.3 million in cash from the DOE final distribution, pending resolution with the DOE of administrative issues associated with certain Kaiser-Hill employee pension and post-retirement benefits, as well as further administrative contract closeout issues, including those associated with the Kaiser-Hill cost reconciliation process. It is possible that there will be disputes between the DOE and Kaiser-Hill as to how these issues should be addressed and dealt with. Such disputes could delay or reduce future distributions of cash from Kaiser-Hill to the Company and could cause a decrease in the value of our common stock.

There are potential risks associated with U.S. Government audits of Kaiser-Hill which could result in disallowed costs or cost reclassifications requiring refunds of cash from Kaiser-Hill to the DOE.

As the contract between Kaiser-Hill and the DOE contains cost reimbursement provisions, the costs invoiced by Kaiser-Hill for reimbursement by the DOE are subject to audit by the U.S. Government. Government audits of costs invoiced by Kaiser-Hill are ongoing. Although Kaiser-Hill has historically provided its estimates of disallowed costs, uncertainties exist with regard to the government audit of Kaiser-Hill. To the extent that costs are disallowed and cash refunds are made to the DOE, future cash distributions from Kaiser-Hill to the Company would be reduced and could cause a decrease in the value of our common stock.

We cannot predict the outcome or timing of a decision and a potential award from the International Chamber of Commerce.

The Company has pending an arbitration award decision from the International Chamber of Commerce concerning a turnkey engineering and construction services contract for construction of a steel mini-mill in the Czech Republic for Nova Hut. In this proceeding, the Company has submitted a claim for $67.5 million dollars and Nova Hut has submitted a counterclaim for $49.7 million. At present, we do not expect a decision to be issued by the International Chamber of Commerce until the second quarter of 2006 and there is no way of predicting what the decision will be. Should an award decision be made that is not favorable to the Company, such a decision may have an adverse impact on the value of the Company’s common stock. In the case of a favorable decision, the Company will still have to pursue collection of the award. It is not possible to predict whether any award that is favorable to the Company (if any) would be collectible or how long collection efforts, even if successful, would take.

18

We face significant contingencies, which may adversely impact our ability to fund our continuing operations and to undertake new operations.

We do not have a significant business plan beyond Kaiser-Hill, and we may undertake new activities with start-up risks.

Our long-term future profitability will be dependent, to a significant degree, on the extent to which we carry out activities other than through Kaiser-Hill, particularly since Kaiser-Hill has entered the closeout phase of its contract with the DOE, and we have received most of the funds we expect to receive from our investment in Kaiser-Hill. Unless and until we further develop plans for such operations, we are unable to determine either the amount of risk that future operations will involve or whether we have the ability to realize long-term profitability. The business opportunities we have begun to explore, such as the establishment of KAMS and our completion of the process to enable MS Builders Insurance Company to offer derivative captive insurance services, are in very early stages, may take a long time to develop, and may never be profitable or successful at all. Our efforts to develop business operations, separate from Kaiser-Hill involve start-up activities with risks specific to activities of this type, which may adversely impact our cash flow and operating results. A decrease in our cash flows and operating results could result in a decrease in the value of our common stock.

We may be unsuccessful in implementing and funding an acceptable benefits funding plan to satisfy our obligation to provide future benefits to a fixed group of retirees.

The Company remains obligated to continue to fulfill the provisions of Old Kaiser’s previously curtailed benefits plan, which provides certain medical and death benefits to a group of retirees. All of the benefits derived from the plan are fully covered by the Company’s self-insurance.

Since the December 2000 approval of the reorganization plan, the Company has been negotiating with the Delaware Bankruptcy Court-appointed Official Committee of Retirees (“OCR”) to design and implement a benefits funding plan that would provide for all retiree benefit obligations going forward.  In an adversary claim hearing in the Delaware Bankruptcy Court held on April 12, 2006, the Court accepted the Company’s proposal to establish a Voluntary Employees’ Beneficiary Association (“VEBA”) to fund retirees’ future medical and death benefits in the present value amount of approximately $6.1 million. The present value pension obligation of $0.3 million will continue to be funded directly by the Company. In addition, in accordance with the Delaware Bankruptcy Court ruling, the Company will establish a declining balance escrow account to fund expected additional future VEBA administrative costs in the event the Company decides to terminate its operations at some future date. The initial escrow fund amount will be $0.6 million and this amount will be reduced by $25,000 for each year that the Company remains in business.

Furthermore, according to the terms of the Delaware Bankruptcy Court decision, after the VEBA has been in place for five years, the Company will be required to undertake an actuarial analysis of the projected net present value of benefits remaining to be paid out. If the remaining VEBA fund amount is then not sufficient to pay the estimated present value benefits obligation, then the Company will be required to contribute the estimated shortfall amount to the VEBA fund. It is not possible to predict at this time whether a shortfall in the VEBA fund would exist after a period of five years and, if so, what the Company’s contribution requirement for a shortfall amount would be in this circumstance. A requirement to fund a significant shortfall in the VEBA fund could result in a decrease in the value of our common stock.

We may be unable to obtain performance guarantees, which may limit our ability to undertake new activities.

Given the reorganization history of Old Kaiser, we may not be able to obtain satisfactory contract performance guaranty mechanisms, such as performance bonds and letters of credit, on satisfactory terms or at all, to the extent such mechanisms are needed for new activities and projects. These factors could limit the nature of the business activities in which we can engage, which may adversely impact our cash flow and operating results and result in a decrease in the value of our common stock.

We may be unable to generate funds to meet our cash flow needs, and we may be unable to access additional capital.

We may be unable to continue to generate sufficient funds to meet our cash flow needs. In the event our cash needs exceed our current estimates, we may not be able to obtain additional capital to meet those needs on favorable terms, or at all. In particular, due to the reorganization history of Old Kaiser and current financial markets, additional capital may not be available to us. An inability to gain access to additional capital could also limit our ability to undertake new activities. Ultimately, an inability to meet our existing obligations or to undertake new activities could adversely impact our cash flow and operating results. A decrease in our cash flows and operating results could result in a decrease in the value of our common stock.

19

We may have to draw down existing cash balances to fund current operating cash needs.

In light of physical completion of Kaiser-Hill’s contract with the DOE, until and unless the Company is successful in developing a new revenue base through new commercial activities or undertakings, it is anticipated that the Company will need to rely on existing cash balances to fund its continuing operations, including overhead costs. This draw down in cash balances could result in a decrease in the value of our common stock.

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS
