BUSINESS UPDATE

Overview

Our business is developing and monetizing as appropriate the remaining assets we received from the KSC bankruptcy. Following is a summary of our material assets other than cash and securities:

KAISER VENTURES LLC AND SUBSIDIARIES

Cash Maximization Strategy Status

In September 2000, Kaiser Inc.’s Board of Directors approved a strategy to maximize the cash ultimately to be distributed to our owners taking into account all circumstances and applicable legal requirements. This strategy was continued with the conversion of Kaiser Inc. to a limited liability company at the end of 2001. Consistent with this strategy, Kaiser Inc. historically completed or entered into a number of transactions which resulted in Kaiser Inc. distributing a total of $12 per unit in cash to its shareholders. TheIn particular the adverse final decision in the federal land exchange litigation in March 2011 negatively impactsimpacted MRC’s ability to pursue the Landfill Project, which in turn altersaltered and adversely impactsimpacted the timing of the continuing implementation of the cash maximization strategy. In addition,However, with the potential sale by Kaiser Recycling of ourits ownership interest in Kaiser Eagle Mountain, Lake Tamarisk Development,the WVMRF, LLC, the Company’s Board of Managers declared and MRC, would have substantially advanced the finalpaid a distribution of $1.50 per Class A Unit to unitholders of record as of May 9, 2012. In addition, funds were reserved for known future liabilities and for possible future contingent liabilities. Further implementation of the cash maximization strategy.strategy is dependent upon, among other things, the sale of its remaining assets, which the Company continues to pursue.

Eagle Mountain Landfill Project and MRC

In 1988, the Company entered into a 100-year lease agreement (the “MRC Lease”) with MRC. MRC was seeking to develop the Company’s former iron ore mine near Eagle Mountain, California into a large, regional rail-haul, municipal solid waste landfill. On May 26, 2000, the Company also entered into a Real Estate Option Agreement (the “MRC Option”) with MRC which would permit MRC to acquire the real property for the Landfill Project upon the terms and conditions set forth in the MRC Option. The MRC Option has not yet been exercised and it currently expires on December 31, 2011,October 29, 2012, if it is not extended by mutual agreement. The Company currently owns approximately 84.247% of the Class B units and 100% of the Class A units of MRC. On October 30, 2011, MRC filed a voluntary petition for relief under Chapter 11 of the United States Bankruptcy. For additional information, please see the discussion above under the first bullet point paragraph in “Item 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS—BUSINESS UPDATE—Overview.”

As part of the proceedings in Bankruptcy Court, MRC will need to develop a plan of reorganization which will include decisions regarding the status of the MRC Lease, the MRC Option and the Landfill Project Sale Agreement, among other things.

Prior Federal Landfill Project Litigation. On September 20, 2005, the U.S. District Court for the Central District of California, Eastern Division, issued its opinion in Donna Charpied,et al., Plaintiffs v.United States Department of Interior, et al., Defendants (Case No. ED CV 99-0454 RT (Mex)) In addition, MRC will consider and inNational Parks and Conservation Association, Plaintiff v.Bureau of Land Management, et al., Defendants (ED CV 00-0041 RT (Mex)). That decision is adversetake action with respect to the Landfill Projectproof of claims filed in the bankruptcy proceeding including whether to accept, reject, compromise or take other action with respect to any particular proof of claim that it sets aside a land exchange completed betweenwas timely and properly submitted. In addition, litigation and threatened litigation have arisen in the Company and BLM in October 1999 and two BLM rights-of-way.

The Company and the U.S. Department of Interior each appealed the decision to the U. S. 9^th Circuit Court of Appeals. On November 10, 2009, a three-judge panelcontext of the U.S. 9^th Circuit Court of Appeals issued its decision in the Company’s land exchange litigation and Landfill Project appeal. In a 2 to 1 decision the majority opinion was adverse to the Landfill Project in that it upheld portions of the prior U. S. District Court decision setting aside the completed land exchange. A slightly modified decision was released on May 19, 2010, by the U.S. 9^th Circuit Court of Appeals but the modified decision did not change any of the conclusions of the majority opinion. We elected to seek U.S. Supreme Court review of the adverse U.S. 9^th Circuit Court of Appeals decision, but the U.S. Supreme Court on March 28, 2011, declined to accept our appeal. On May 10, 2011, the U.S. District Court issued its order remanding the actions “to the BLM for proceedings consistent with the Ninth Circuit’s May 19, 2010 amended opinion.” With the decision of the U.S. Supreme Court not to hear the appeal of the adverse decision of the 9^th Circuit Court of Appeals, there is no longer any pending litigation and the adverse federal litigation is final and fully concluded as no further appeals are available.MRC bankruptcy.

MRC Financing.Since Kaiser became an owner of MRC in 1995, MRC has been financed through a series of private offerings of securities to its existing equity owners. As a result of a private placement completedHowever, the Company has determined that it will not provide any future equity financing to MRC to pursue the Landfill Project, but MRC may need additional funds to complete its bankruptcy. Under certain circumstances, Kaiser LLC as well as others may become “debtor-in-possession” lenders to MRC. While Kaiser has made the determination that it will not provide future equity financing to MRC to pursue the Landfill Project, other parties may desire to continue to pursue the Landfill Project in September 2011, MRC raised total proceeds of approximately $1.3 million, of which Kaiser contributed $1,146,344 which increased Kaiser’s ownership interest in MRC from 83.13% to 84.247%. The amount raised in the September 2011 private placement is far short of the total estimated amount of funds that would be necessary to implement any “fix” of the land exchange.some manner.

West Valley Materials Recovery and Transfer Station

West Valley MRF,Background. WVMRF, LLC was formed in June 1997 by Kaiser Recycling Corporation (now Kaiser Recycling, LLC (formerly Kaiser Recycling, Inc.)), a wholly-owned subsidiary of Kaiser, and West Valley Recycling & Transfer, Inc., a wholly-owned subsidiary of Burrtec Waste Industries, Inc. (“Burrtec”). This entity was formed to construct and operate the materials recovery facility and is referred to as the West Valley MRF.WVMRF, LLC. This facility is permitted to receive up to 7,500 tons per day of municipal solid waste. Currently,Prior to April 2, 2012, the facility iswas processing approximately 3,000 – 3,500 + tons per day of municipal solid waste and recyclable materials.

ConstructionSale of Ownership Interest.On April 2, 2012, Kaiser LLC, Kaiser Recycling, Burrtec Waste Industries (“Burrtec”) and West Valley Recycling & Transfer, Inc. (“Buyer”), a wholly owned subsidiary of Burrtec, entered into that certain Purchase Agreement (the “Purchase Agreement”) whereby Kaiser Recycling sold its ownership interest in WVMRF, LLC to Buyer. The sale transaction closed on the same day as the Purchase Agreement was entered into by the parties to the agreement. Kaiser Recycling sold its ownership interest in WVMRF, LLC for a gross cash sales price of approximately $25,769,000. The Company recorded a gain of $20,588,000 in the second quarter of 2012. The Company’s guaranty of the West Valley MRF was financed primarily by bonds issued by theoutstanding California Pollution Control Finance Authority. The bonds have a variable interest rate that is adjusted weekly. The rates during the first nine months of 2011 have ranged from a low of 0.15% to a high of 0.40%; however, the average rate for the first nine months of 2011 has been 0.29%. These rates do not include the credit enhancement fee of approximately 1.25%, which is paid to the bank providing the credit enhancement. The bank that provides the letters of credit that support the Pollution Control Finance Authority bonds extended the letters of credit for the 1997 Phase 1 bonds through June 30, 2012, which is their stated date of maturitywas terminated. However, existing environmental obligations and for the 2000 Phase 2 bonds through June 2016.

Risks. There are a number of risks associated with the West Valley MRF which are discussed in more detail in the Company’s Annual Report on Form 10-K for 2010. Waste volumes remain negatively impacted by the down-turn in the California economy. In addition, any material reduction in commodity prices would negatively impact the revenues, margins and net income of the West Valley MRF. Governmental regulation and competition for and loss of expiring waste contracts would also negatively impact the West Valley MRF.

OPERATING RESULTS

Note on WVMRF, LLC

The operating results of the Company during the first quarter of 2012 reflect our fifty percent (50%) ownership interest in WVMRF, LLC, for the 3 month period ended February 29, 2912. In addition, even though we sold our ownership interest in WVMRF, LLC on April 2, 2012, our second quarter operating results reflect the results of WVMRF, LLC’s March 2012 operations. This is due to the time required to close the books of the WVMRF, LLC and in keeping with past practice, there is a one month delay in reporting the results of WVMRF, LLC.

Summary of Revenue Sources

Due to the nature of the Company’s projects and the Company’s recognition of revenues from non-recurring items, historical period-to-period comparisons of total revenues may not be meaningful for developing an overall understanding of the Company. Therefore, the Company believes it is important to evaluate the trends in the components of its revenues as well as the recent developments regarding its long-term ongoing and interim revenue sources.

in cash and cash equivalents is $580,000$250,000 and $124,000$534,000 held solely for the benefit of MRC at SeptemberJune 30, 20112012 and December 31, 2010,2011, respectively.

Below is a table showing the major changes in cash during 2011:2012:

Working Capital. During the first ninesix months of 2011,2012, current assets decreased $1,099,000increased by $12,603,000 to $5.7$17.0 million, while current liabilities increased $21,000decreased $174,000 to $2.0 million.$2,057,000. The decreaseincrease in current assets was the net result of decreases in short term investments of $1,437,000, and a decrease in restricted cash of $105,000. These decreases were partially offset by(a) an increase in Accounts Receivable of $35,000 and $408,000 in cash and equivalents as discussed above.above; (b) an increase in accounts receivable and other of $357,000; and (c) an increase in restricted cash of $28,000 offset by a decrease in short term investments of $462,000. The increasedecrease in current liabilities is the result of increasesa decrease of $14,000 and $7,000$248,000 in accounts payable andoffset by an increase in accrued liabilities respectively.of $74,000. As a result, net working capital decreasedincreased during the first ninesix months of 20112012 by $1,120,000$12,777,000 to $3.7 million$14,958,000 at SeptemberJune 30, 2011.2012.

Below is a table showing the major changes in working capital.

KAISER VENTURES LLC AND SUBSIDIARIES

Accounts Receivable and Other (Net). During the six first ninesix months of 2011,2012, accounts receivable and other current assets increased by $35,000$357,000 primarily due to an increaseincreases in trade accounts receivable and prepaid insurance.

Short-Term Investments. During the first ninesix months of 2011,2012, short-term investments decreased by $1,437,000.$462,000. This is primarily the result of the sale of investments to provide operating funds. On SeptemberJune 30, 2011,2012, the Company had $2.7$2.2 million of its excess cash reserves invested in such investments. Investments are marked to market and unrealized earnings or loss are reflected in the value of the investment and in income for the period for which they are earned.

Investments. The Company’s equity share of income from the investment in the West Valley MRF, which totaled $1,690,000$391,000 for the first ninesix months of the year, was offset by the receipt of cash distributions totaling $1,250,000$750,000 resulting in a $440,000 increase$359,000 decrease to the Company’s investment in the West Valley MRF. In addition, the Company sold its entire member interest in the West Valley MRF, LLC on April 2, 2012, so the Company’s investment in the West Valley MRF, LLC was $0 at June 30, 2012.

As previously stated, the investment in the MRC Landfill Project was determined to be impaired and, therefore, was written-down by $6,683,000 during the first quarter of 2011 which was charged to earnings. As required by the ASC, all subsequent Eagle Mountain Landfill expenses will be expensed as incurred.

Other Assets. For the first ninesix months of the year, there was a decrease in other assets of $214,000$158,000 which is the net result of the amortization of the environmental insurance policy of $225,000,$150,000, and an

KAISER VENTURES LLC AND SUBSIDIARIES

increase in accumulated depreciation as of September 30, 2011 of $14,000, which were partially offset by the establishment of a $25,000 refundable legal retainer.$8,000 related to buildings and equipment.

Environmental Remediation. The Company purchased, in 2001, a 12-year $50 million insurance policy to cover substantially any and all environmental claims (up to the $50 million policy limit) relating to the historical operations of the Company. As of SeptemberJune 30, 2011,2012, based upon current information, we estimate that our future environmental liability related to certain matters and risks not assumed by CCG Ontario, LLC, a subsidiary of Prologis, in its purchase of the Mill Site Property in August 2000 would be approximately $2.7$2.3 million for which a reserve has been established. See Note“Note 2. “ENVIRONMENTAL—ENVIRONMENTAL MATTERS”. In the event a claim for damages is filed against the Company that relates to this reserve, management believes that the claim may be covered by insurance depending upon the nature and timing of the claim. In addition, in connection with the Tar Pits Parcel now owned by Kaiser Recycling, LLC, insurance was purchased in the second quarter of this year to cover possible contingent environmental related liabilities and a third party escrow of $363,000 in cash was established benefitting WVMRF, LLC and others. This amount was charged against the Company’s environmental reserve which encompassed this specific environmental exposure. The $113,621 premium for the purchased policy was paid from the cash escrow.

Non-Controlling Interest.Interest in MRC. During the first ninesix months of 2011,2012, the Non-Controlling Interest decreased by $1,032,000$42,000 from $3,136,000$2,057,000 as of December 31, 20102011 to $2,104,000$2,015,000 as of SeptemberJune 30, 2011 due to2012, which is the following factors: (i) Netnet loss attributable to Non-Controlling Interestnon-controlling interest for the ninesix month period amounted to $1,186,000 which was largely related to the write-down of the Eagle Mountain Landfill investment recorded in first quarter of 2011; and (ii) In September 2011, MRC completed a private placement whereby they raised total proceeds of $1.3 million, of which approximately $154,000 was contributed by Non-Controlling Interests. Current MRC expenditures are no longer being capitalized but are charged to operations.period. As of SeptemberJune 30, 20112012 the resulting Non-Controlling Interestnon-controlling interest is $2,104,000,$2,015,000, which relates to the approximate 15.8% ownership interest in MRC that the Company does not own.

Contingent Liabilities. The Company has contingent liabilities more fully described above and in the notes to the financial statements.

Critical Accounting Policies

KAISER VENTURES LLC AND SUBSIDIARIES

The Company’s accounting policies are more fully described in the Notes to the Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2010.2011. As disclosed in the Notes to the 20102011 Annual Financial Statements, the preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions about future events that affect the amounts reported in the consolidated financial statements and accompanying notes. Future events and their effects cannot be determined with absolute certainty and therefore, the determination of estimates requires the exercise of judgment. Actual results inevitably will differ from those estimates, and such differences may be material to the consolidated financial statements.

The Company believes the following critical accounting policies, which comply with the ASC, are important to the portrayal of the Company’s financial condition and results.

Investments. The Company accounts for investments under Section 320-10 of the ASC. The Company invests its excess cash reserves in highinvestment grade or better commercial paper (Standard & Poor’s rating of “A” or above), and U.S. government bonds which it classifies as “available-for-sale” and which are recorded at the purchase price of the security plus or minus the discount or premium paid. Investments are marked to market and unrealized earnings are reflected in income for the period in which they are earned. However, the Company expects to hold these investments to maturity, thereby mitigating any fluctuations in fair value.maturity.

Investment in West Valley MRF, LLC. The Company accountsaccounted for its investment in West Valley MRF,WVMRF, LLC, the owner of West Valley MRF, under the equity method of accounting because of the Company’s 50% non-controlling ownership interest. However, as discussed elsewhere in this Report, the Company’s ownership interest in WVMRF, LLC was sold on April 2, 2012.

Landfill Permitting and Development. Through its 84.247% interest in MRC, the Company has been developing, for sale to a municipal entity or operating company, its property known as the Eagle Mountain Site in the California desert for use as a rail-haul municipal solid waste landfill. Pursuant to

KAISER VENTURES LLC AND SUBSIDIARIES

Section 970-10 of the ASC, capitalizable landfill site development costs are recorded at cost and will be expensed when management determines that the capitalized costs provide no future benefit. However, as discussed in more detail in this Report on Form 10-Q, effective June 30, 2010 and March 31, 2011, there was a determination of impairment of MRC’s investment in the Eagle Mountain Landfill Project which resulted in write-downs of the carrying amount of such investment in our financial statements. With the determination that an impairment exists no further costs have been or will be capitalized.

Environmental Insurance and Environmental Remediation Liabilities. The Company’s $3.8 million premium for the prospective insurance policy, which was reduced by a refund from the insurance carrier, is capitalized as a long-term asset and is being amortized on a straight-line basis over the twelve (12) year term of the policy. To the extent a pre-existing liability has not been recorded, claims made for environmental matters are recorded as litigation accruals in the Company’s consolidated financial statements pursuant to Section 450-10 of the ASC when it becomes probable that a loss has been incurred and the amount of such loss can be reasonably estimated. Claims accepted by the insurance company pursuant to coverage under the policy are recorded as insurance receivables when coverage is accepted and the amount to be paid by the insurance company can be reasonably estimated. In addition, a new limited environmental insurance policy for a ten year term was purchased by KSC Recovery, LLC as more fully discussed in “WEST VALLEY MRF AND TRANSFER STATION—Sale of Ownership Interest” above.

Revenue Recognition. Revenues are recognized when the Company has completed the earnings process and an exchange transaction has taken place.

Conditional Asset Retirement Obligations. The Company accounts for certain asset retirement obligations at Eagle Mountain pursuant to ASC 410Accounting for Asset Retirement and Environmental Obligations.

KAISER VENTURES LLC AND SUBSIDIARIES

Long-Lived Assets. In accordance with Section 360 of the ASC, long-lived assets are evaluated for potential impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. As discussed in more detail in this Report of Form 10-Q, effective June 30, 2010 and March 31, 2011, there were determinations of impairment of the Eagle Mountain Landfill investment, a long-lived asset, which resulted in write-downs of the carrying amount of such investment in our financial statements.

BUSINESS OUTLOOK

The statements contained in this Business Outlook, as well as in “Part I—Item 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS—Overview”, are based upon current operations and expectations. In addition to the forward-looking statements and information contained elsewhere in this Report on Form 10-Q, these statements are forward-looking and, therefore, actual results may differ materially. See the Company’s disclosure regarding forward-looking statements in the section entitled “Forward-Looking Statements” above.

Ongoing Operations. As noted above, our revenues from ongoing operations have, in the past, generally been derived from the performance of our major long-term development projects and investments. We have previously sold most of our projects and investments. Ourinvestments and as previously discussed on April 2, 2012, we sold our fifty percent (50%) ownership interest in WVMRF, LLC. Accordingly, our principal remaining assets and projects, other than cash and securities, are: (i) our ownership interest in MRC, however, MRC filed a voluntary bankruptcy petition under Chapter 11 of the U.S. Bankruptcy Code on October 30, 2011; (ii) our 50%100% equity ownership of the West Valley MRF; (iii) miscellaneous property at or near the Eagle Mountain Townsite;KEM which owns and (iv) the other resourcescontrols approximately 10,000 acres at the Eagle Mountain Site on our fee owned property such as theor in which millions of tons of iron ore, stockpiled rock and other mineral resources.resources are present; and (iii) our 100% equity ownership interest in Lake Tamarisk Development which owns property near the Eagle Mountain Site. We have no material ongoing operations except in connection with such remaining assets and projects.projects and in connection with addressing any liabilities we may have. Our principal sources of ongoing income areover the last several years have been derived from the West Valley MRF,WVMRF, LLC, investment earnings and from miscellaneous income generated at the Eagle Mountain Site.

In regard to the West Valley MRF, the most significant factors affecting our future equity income will continue to depend upon: (i) the ability of the West Valley MRF to retain customers and waste volumes

KAISER VENTURES LLC AND SUBSIDIARIES

at attractive processing rates; (ii) recyclable commodity prices; (iii) the ability to increase prices to reflect increases in such items as transportation, labor and disposal costs; and (iv) future competition from competing facilities. The performance of the West Valley MRF, which was negatively impacted by the recent world-wide economic recession, has significantly improved in the first nine months of 2011 versus 2010 primarily as As a result of increasing commodity prices. However, such improvements generally plateaued in the third quartersale of 2011. Additionally, the West Valley MRF is continuing the process of evaluating possible waste-to-energy and composting projects that might be capable of utilizing a portion of the municipal solid waste received at the facility. Finally, as part of our cash maximization strategy, we intend to evaluate any potential offers to purchase our interest in West Valley or other alternatives in light of our primary objective of maximizing value. West Valley currently generates more than sufficient cash flow to fund its cost of operations and does not require additional investment by us.WVMRF, LLC, no further distributions will be received from WVMRF, LLC.

MRC.MRC. As discussed in more detail in “Part I—Item 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS—BUSINESS UPDATE—Overview,” on October 30, 2011, MRC filed a voluntary petition in bankruptcy pursuant to Chapter 11 of the U.S. Bankruptcy Code. The filing was necessary to protect and preserve MRC’s assets and options. Depending upon the results of the bankruptcy process, it is possible that the value of Kaiser’s investment in MRC could be further impaired.

Mill Site Property. The only remaining Mill Site Property owned by the Company is an approximate five acre parcel referred to as the Tar Pits Parcel.Parcel which is now owned by Kaiser Recycling. CCG Ontario, LLC substantially completed all material environmental remediation of this parcel pursuant to the terms of its agreement during 2002. CCG Ontario does have ongoing operations and maintenance obligation with respect to the Tar Pits Parcel. West ValleyWVMRF, LLC has the right to purchase the Tar Pits Parcel for $1.00. Effective April 2, 2012, WVMRF, LLC leased material portions of the Tar Pits Parcel from Kaiser Recycling. The lease is for 50 years with the right to extend the lease for 50 years in exchange for: (i) payment of all the property taxes for the Tar Pits Parcel; (ii) insuring the Tar Pits Parcel and naming Kaiser Recycling as an additional insured for general liability purposes; and (iii) performing various maintenance and security obligations on the property being leased. In addition, a cash escrow was established in the amount of $363,000 benefiting WVMRF, LLC and others in connection with possible contingent environmental and environmental related actions, a reserve for which had been previously recorded. A limited environmental insurance policy with a term of ten years was purchased for $113,621 with the policy premium being paid from the escrowed amount.

KAISER VENTURES LLC AND SUBSIDIARIES

Cash Maximization Strategy. In September 2000, Kaiser Inc.’s Board of Directors approved a strategy to maximize the cash ultimately to be distributed to our owners taking into account all circumstances and applicable legal requirements. This strategy was continued with the conversion of Kaiser Inc. to a limited liability company at the end of 2001. Consistent with this strategy, Kaiser Inc. historically completed or entered into a number of transactions which resulted in Kaiser Inc. distributing a total of $12 per unit in cash to its shareholders. The nowLengthy, but adversely completed, litigation involving the Landfill Project delayed the implementation of the goals of the cash maximization strategy. In particular the adverse final adversely-decideddecision in the federal land exchange litigation in connection withMarch 2011 negatively impacted MRC’s ability to pursue the Landfill Project, alterswhich in turn altered and adversely impactsimpacted the timing of the continuing implementation of the cash maximization strategy. However, with the sale by Kaiser Recycling of its ownership interest in WVMRF, LLC, the Company’s Board of Managers declared and paid a distribution of $1.50 per Class A Unit to unitholders of record as of May 9, 2012. In addition, funds were reserved for known future liabilities and for possible future contingent liabilities. Further implementation of the cash maximization strategy is dependent upon, among other things, other asset sales.

Corporate Overhead. GivenWith the sale of our current assets and projects, it is unlikely that we will be able to further reduce personnel and corporate overheadownership interest in WVMRF, LLC, there was a reduction during the second quarter in the near future. However, as we divest our remaining assets, we intend to further reduce corporate staffing and overheadof the Company’s accounting department to reflect the reduced requirements resulting from the sale of our interest in WVMRF, LLC and of our remaining operations and projects. The costs of such reductions, shall beincluding the payment of severance, was recorded atduring the time the decision to make such reductions is made by the Company.second quarter of 2012.

Capital Resources.Kaiser LLC expects that its current cash balances and short-term investments together with cash generated from the West Valley MRF,current and any future asset sales as well as expense reductions will be sufficient to satisfy the Company’s ongoing projected operating cash requirements for at least the next twelve months.months even after payment of the $1.50 per unit distribution declared by the Board of Managers on May 9, 2012.

MRC Bankruptcy. On October 30, 2011, MRC filed a voluntary petition relief under Chapter 11 of the U.S. Bankruptcy Code. MRC continues to operate as a debtor in possession. MRC’s bankruptcy is not currently expected to have a material direct adverse result on Kaiser except that Kaiser will incur attorneys’ fees and costs as a result of the bankruptcy and Kaiser may elect to become a debtor-in-possession lender to MRC to provide the funds necessary to complete the bankruptcy process.

WithinAs of the 90 days prior toend of the date ofperiod covered by this report, the Company carried out an evaluation, under the supervision and with the participation of the Company’s management, including the Company’s Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of the Company’s disclosure controls and procedures pursuant to Exchange Act Rule 13a-14.

KAISER VENTURES LLC AND SUBSIDIARIES

Based on its review of the Company’s disclosure controls and procedures, the Chief Executive Officer and Chief Financial Officer have concluded that the Company’s disclosure controls and procedures are effective in timely alerting them to material information relating to the Company (including its subsidiaries) that is required to be included in the Company’s periodic Securities and Exchange Commission filings. Specifically, since 2007, the Company has: (a) requested annually that all of the critical employees, officers and Members of the Board of Managers of the Company complete an extensive internal control and risk management questionnaire; and (b) internally reviewed and tested the implementation of its internal controls against the Company’s written control procedures. The above conclusions are based upon the work performed. There were no significant changes in internal controls or in other factors that could significantly affect these controls subsequent to the date of their evaluation, including any corrective actions with regard to significant deficiencies and material weaknesses.

KAISER VENTURES LLC AND SUBSIDIARIES

However, with the termination of two accounting positions due to the sale of Kaiser Recycling, Inc.’s ownership interest in WVMRF, LLC, including the termination of the Company’s controller position as of June 30, 2012, going forward there will be fewer individuals that will be able to review and correct any omission or errors that may occur in the Company’s accounting controls and procedures. The effect of this will be mitigated by the part-time employment of the now retired former controller. As previously noted, the effectiveness of the Company’s disclosure controls and procedures are evaluated effective as of the end of each calendar quarter.

Note 2. ENVIRONMENTAL MATTERS

The Company purchased an insurance policy effective June 30, 2001 that is designed to provide broad prospective commercial general liability, pollution legal liability, and contractual indemnity coverage for the Company’s ongoing and historical operations. The policy has a twelve (12) year term and limits of $50 million in the aggregate for defense and indemnity, with no deductible or self-insured retention. The policy is designed to provide coverage for future claims in excess of the Company’s existing and historic insurance policies; however, to the extent that these other insurance policies are not responsive to a claim, the policy will provide first dollar coverage for a claim resulting from property damage, personal injury, bodily injury, cleanup costs or violations of environmental laws. The policy also provides for a broad defense of claims that may be brought against the Company. The policy is specifically intended to provide additional coverage for potential liabilities arising from

KAISER VENTURES LLC AND SUBSIDIARIES

pollution conditions or known and/or potential asbestos-related claims. The policy also provides contractual indemnity coverage for scheduled indemnity obligations of the Company arising from, e.g., prior corporate transactions and real estate sales. The Company expects this policy will cover substantially any and all environmental claims (up to the $50 million policy limit) relating to the historical operations of the Company.

The aggregate cost for this policy was approximately $5.8 million, of which, based upon discussions among the respective members of the Boards of Directors, KSC Recovery paid $2 million and the Company paid the balance of approximately $3.8 million. The portion of the policy paid by KSC Recovery was expected to cover known and/or potential asbestos claims; while the portion of the policy paid by the Company was expected to cover future potential claims arising from the Company’s historical operations.

The Company’s original $3.8 million premium for the prospective insurance policy was capitalized as a long-term asset and is being amortized on a straight-line basis over the 12 year term of the policy. To the extent a pre-existing liability has not been recorded, claims made for environmental matters are recorded as litigation accruals in the Company’s consolidated financial statements pursuant to Section 450-10 of the ASC when it becomes probable that a loss has been incurred and the amount of such loss can be reasonably estimated. Claims accepted by the insurance company pursuant to coverage under the policy are recorded as insurance receivables when coverage is accepted and the amount to be paid by the insurance company can be reasonably estimated. Generally, unless previously accrued, the liability and the receivable relating to claims covered by this policy should occur in the same accounting period, thereby having no adverse or beneficial impact on the Company’s operating results for that accounting period.

Note 3. INVESTMENTSIn addition to the foregoing policy, an additional insurance policy with a term of ten years covering certain possible contingent environmental and other related events that could arise and impact the West Valley MRF, LLC and others was purchased by Kaiser Recycling during the second quarter. The policy premium of $113,621 was paid from the escrow account originally totaling $363,000 that was established as a result of the sale of Kaiser Recycling, LLC’s ownership interest in WVMRF, LLC. The amount of this escrow was charged against the Company’s existing environmental liability reserve.

The Company has an Investment Policy which provides for the investment of excess cash balances primarily in bond funds, commercial paper, and debt instruments. At SeptemberJune 30, 20112012 the Company had all of its investments in bonds, bond funds or high grade commercial paper (Standard & Poor’s rating of “A” or above) which is classified as “available-for-sale.”

Pursuant to Section 825-10 of the ASC, the Company at the end of a period, compares the actual market value to the actual cost and uses that calculation to determine any gain or loss on the maturity or sale of each available-for-sale investment.

The following is a summary of the fair value of investment securities classified as “available-for-sale” as of SeptemberJune 30, 20112012 and December 31, 2010.2011. For each item included in the table below the gains or losses from Fair Value reporting are included in income for the quarter.

KAISER VENTURES LLC AND SUBSIDIARIES

Note 4. FAIR VALUE OF FINANCIAL ASSETS AND FINANCIAL LIABILITIES

ASC 825-10 defines fair value as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required or permitted to be recorded at fair value, the Company considers the principal or most advantageous market in which it would transact and considers assumptions that market participants would use when pricing the asset or liability, such as inherent risk, transfer restrictions, and risk of nonperformance. ASC 825-10 establishes a fair value hierarchy that requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. ASC 825-10 establishes three levels of inputs that may be used to measure fair value:

Level 1—Quoted prices in active markets for identical assets or liabilities.

Level 2—Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets with insufficient volume or infrequent transactions (less active markets); or model-derivedmodel- derived valuations in which all significant inputs are observable or can be derived principally from or corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3—Unobservable inputs to the valuation methodology that are significant to the measurement of fair value of assets or liabilities.

To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for disclosure purposes, the level in the fair value hierarchy within which the fair value measurement is disclosed is determined based on the lowest level input that is significant to the fair value measurement.

Due to the time required to close the books of the West Valley MRF, LLC and in keeping with past practice, there is a one month delay in reporting the results of West Valley MRF, LLC. Thus, even though the closing on the sale of Kaiser Recycling, LLC’s ownership interest occurred on April 2, 2012, due to this one month delay, there is one month’s of the Company’s share of the income for West Valley MRF, LLC during the second quarter of 2012.

The increase in Members’ Equity for the West Valley MRF between November 30, 2010 and August 31, 2011, is primarily due to the fact that net income exceeded cash distributions during this period.

The Company recognized equity income from the West Valley MRF of $1,690,000$391,000 and $1,314,000$1,102,000 for the first ninesix months of 2012 and 2011, and 2010, respectively.

Note 6. EVALUATION OF LONG-LIVED ASSETS

In accordance with Section 360 of the ASC, long-lived assets are evaluated for potential impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. Our reviews as of SeptemberJune 30, 2011,2012, concluded that no impairment of the following long-lived assets had occurred: (a) our 50% ownership interest in the West Valley MRF because the West Valley MRF continues to generate significant net incomeoccurred and positive cash flow; and (b) our other real estate and building and equipment are recorded at the lower of cost or fair market values.

With the denial of our appeal to the U.S. Supreme Court, our quarterly analysis pursuant to the ASC of whether the MRC investment in Eagle Mountain Landfill Project was impaired, resulted in a determination of impairment and a write-down of the carrying amount of the MRC investment in Eagle Mountain Landfill Project as of March 31, 2011. As required by GAAP, the impairment determination and resulting calculation of fair value of the carrying amount of the MRC investment in Eagle Mountain Landfill Project were made utilizing a probability analysis of the remaining options with regard to the Landfill Project after the U.S. Supreme Court declined to accept the petition requesting further review of the adverse U.S. 9^th Circuit Court of Appeals decision as of March 28, 2011. The total amount of the write-down was $6,683,000 which was charged to earnings in the first quarter of 2011. Previously, in 2010, the Company recorded a $12,504,000 write-down of MRC’s Eagle Mountain Landfill Project investment as a result of its quarterly evaluation of long-lived assets and its determination that impairment had occurred asAs of June 30, 2010. As of September 30, 2011,2012, there were no events or changes in circumstances that indicated that the carrying amount of MRC’s investment in Eagle Mountain Landfill Project may not be recoverable. Possible further impairment in the MRC investment in Eagle Mountain Landfill Project resulting from MRC’s bankruptcy filing on October 30, 2011, may be required in the future as the impact of the bankruptcy filing is determined.

Note 7. COMMITMENTS AND CONTINGENCIES

Environmental Contingencies. As discussed in Note 2, effective June 30, 2001, the Company purchased a 12-year $50 million insurance policy which is expected to cover substantially any and all environmental claims (up to

KAISER VENTURES LLC AND SUBSIDIARIES

the $50 million policy limit) relating to the historical operations of the Company. To the extent a pre-existing liability has not been recorded, claims made for environmental matters are recorded as litigation accruals in the Company’s consolidated financial statements pursuant to ASC 450-10 when it becomes probable that a loss has been incurred and the amount of such loss can be reasonably estimated. Claims accepted by the insurance company pursuant to coverage under the policy are recorded as insurance receivables when coverage is accepted and the amount to be paid by the insurance company can be reasonably estimated.

As of SeptemberJune 30, 2011,2012, the Company estimates, based upon current information and discussions with environmental consultants, that its future environmental liabilities related to certain matters not assumed by CCG Ontario, LLC in its purchase of a substantial portion of Kaiser’s former Fontana mill site property (“Mill Site Property”), including a certain groundwater matter as well as potential matters at Eagle Mountain and at other historical locations, will be approximately $2.7$2.3 million. In the event that a future environmental claim for damages is filed against the Company such claim may be covered by insurance depending upon the nature and timing of the claim.

Previous Landfill Project Litigation. There currently is no pending litigation involvingIn addition, an insurance policy covering certain possible contingent environmental and other related events that could arise and impact the Landfill Project. Two lawsuits were filed in U.S. District Court located in Riverside County challenging the completed federal land exchange. On September 20, 2005, the U.S. District Court for the Central District of California, Eastern Division, issued an opinionWVMRF and order which concluded that the land exchange be reversed and the case be sent backothers subsequent to the BLM for further action consistent with the opinion. MRC and the U.S. Department of Interior appealed the decision to the U. S. 9^th Circuit Court of Appeals. In November 2009, a three judge panelsale of the U.S. 9^th Circuit CourtCompany’s interest in the WVMRF was purchased by Kaiser Recycling during the second quarter. The policy premium of Appeals released its decision on$113,621 was paid from the matter. The majorityexisting escrow account established by the Company at the time of the panel affirmed and reversed in part the U.S. District Court decision. The dissenting judge would have found in the Company’s and BLM’s favor on all matters. MRC sought further review of this decision by a broader panel of U.S. 9^th Circuit of appeals judges but on July 30, 2010, such reviewsale. These potential contingent environmental related events for which insurance coverage was denied by the 9^th Circuit. On March 28, 2011, the U.S. Supreme Court denied MRC’s request to further review the prior adverse decisionpurchased existed regardless of the U.S. 9^th Circuit Courtsale of Appeals. Thus,Kaiser Recycling’s ownership interest in WVMRF, LLC but such sale did accelerate the previously existing federal land exchange litigation is final as there is no further right of appeal.timing on fully addressing such potential contingent liabilities.

MRC Financing. Since Kaiser became an owner of MRC in 1995, MRC has been financed through a series of private placements to its existing equity owners. As a result of a private placement completed in September 2011, MRC raised total proceeds of approximately $1,300,000, of which amount Kaiser contributed $1,146,344, which increased Kaiser’s ownership interest in MRC from 83.13% to 84.247%.

Contingent DistributionsCompensation Expense on Class B, C and D Units. Upon the sale of certain of the Company’s assets at a price equal to or greater than certain minimum sales prices, distributionsadditional compensation payments will be made on the Class B, C and D Units in accordance with their respective terms. With the sale of Kaiser Recycling, LLC’s ownership interest in West Valley MRF, LLC, compensation payments totaling $771,000 were due and paid during the second quarter of 2012 in accordance with the terms and conditions of the Company’s Class C and D Units.

Restricted Cash.Restricted Cash consists primarily of certificates of deposit used to secure certain letters of credit that provide indemnification to governmental entities regarding landfill project approvals and mining rights and other mine related matters. During the second quarter of 2012 an additional certificate of deposit in the amount of $28,000 was acquired to amend the indemnification to the County of Riverside.

Note 8. RECENT ACCOUNTING PRONOUNCEMENTS

From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (“FASB”) that are adopted by the company as of the specified effective date. Unless otherwise discussed, management believes that the impact of recently issued standards, which are not yet effective, will not have a material impact on the company’s consolidated financial statements upon adoption.

In September 2011, the FASB issued an accounting standards update that gives an entity the option to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test. This guidance will be effective for annual goodwill impairment tests performed for fiscal years beginning after December 15, 2011, with early adoption permitted. The adoption of the guidance will not have a material impact on the consolidated financial statements.

KAISER VENTURES LLC AND SUBSIDIARIES

In June 2011, the FASB issued guidance regarding the presentation of comprehensive income. The new standard requires the presentation of comprehensive income, the components of net income and the components of other comprehensive income either in a single continuous

KAISER VENTURES LLC AND SUBSIDIARIES

statement of comprehensive income or in two separate but consecutive statements. The new standard also requires presentation of adjustments for items that are reclassified from other comprehensive income to net income in the statement where the components of net income and the components of other comprehensive income are presented. The updated guidance is effective on a retrospective basis for financial statements issued for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2011. The adoption of this guidance willdid not have a material impact on our consolidated financial statements.

In May 2011, the FASB issued additional guidance on fair value measurements that clarifies the application of existing guidance and disclosure requirements, changes certain fair value measurement principles and requires additional disclosures about fair value measurements. The updated guidance is effective on a prospective basis for financial statements issued for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2011. The adoption of this guidance willdid not have a material impact on our consolidated financial statements.

Note 9. SUBSEQUENT EVENTS

On October 30, 2011, MRC filed a voluntary petition for relief under Chapter 11 of the United States Bankruptcy Code in the United States Bankruptcy Court for Central District of California, Riverside Division, bankruptcy case number 6:11-bk-43596 (the “Bankruptcy Court”). MRC will continue to operate its business as a “debtor in possession” under the jurisdiction of the Bankruptcy Court and in accordance with the applicable provisions of the Bankruptcy Code, Rules and orders of the Bankruptcy Court. The petition in bankruptcy was filed by MRC due to threatened litigation by the District to compel MRC at its sole expense and risk to further proceed with the permitting of the landfill which would involve substantial additional financial resources and time, neither of which MRC has. Management does not currently believe that MRC’s bankruptcy filing will have a material impact on Kaiser’s operations.

On October 12, 2011, Kaiser Ventures executed an option and purchase agreement whereby the option holder could purchase Kaiser’s ownership interest in MRC, in Kaiser Eagle Mountain, LLC, the owner of the property at Eagle Mountain, and in Lake Tamarisk Development, LLC, the owner of property at Lake Tamarisk. Such purchase was subject, in all instances, to the rights of the District to acquire the Landfill Project on or before October 31, 2011. The option holder was also willing to purchase the ownership interests in MRC that Kaiser did not own. However, as a result of the actions of the District and the bankruptcy filing by MRC described above, the option holder did not exercise its option. The performance of the option and purchase agreement was tolled for a limited period and that tolling period will lapse without further extension.
