NOTES TO INTERIM CONSOLIDATED FINANCIAL STATEMENTS

(In millions of dollars, except share and per share amounts and as otherwise indicated)

1. Summary of Significant Accounting Policies

This Quarterly Report on Form 10-Q (this "Report") should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2012.

Organization and Nature of Operations. Kaiser Aluminum Corporation (together with its subsidiaries, unless the context otherwise requires, the “Company”) specializes in the production of semi-fabricated specialty aluminum products, such as aluminum sheet and plate and extruded and drawn products, primarily used in aerospace/high strength, general engineering, automotive, and other industrial end market applications. The Company has one operating segment, Fabricated Products. See Note 11 for additional information regarding the Company’s reportable segment and its other business units.

Principles of Consolidation and Basis of Presentation. The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries and are prepared in accordance with United States generally accepted accounting principles (“GAAP”) and the rules and regulations of the Securities and Exchange Commission (the “SEC”) applicable for interim periods and therefore, do not include all information and footnotes necessary for a fair presentation of financial position, results of operations, and cash flows. The results of operations for the Company’s interim periods are not necessarily indicative of the results of operations that may be achieved for the entire 2013 fiscal year. The financial information as of December 31, 2012 is derived from the Company’s audited consolidated financial statements and footnotes for the year ended December 31, 2012 included in our Annual Report on Form 10-K.

Use of Estimates in the Preparation of Financial Statements. The preparation of financial statements in accordance with GAAP requires the use of estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities known to exist as of the date the financial statements are published, and the reported amounts of revenues and expenses during the reporting period. Uncertainties with respect to such estimates and assumptions are inherent in the preparation of the Company’s consolidated financial statements; accordingly, it is possible that the actual results could differ from these estimates and assumptions, which could have a material effect on the reported amounts of the Company’s consolidated financial position and results of operations.

Inventories. Inventories are stated at the lower of cost or market value. Finished products, work-in-process and raw material inventories are stated on the last-in, first-out (“LIFO”) basis. The Company recorded net non-cash LIFO benefits of approximately $3.7 and $2.9 during the quarters ended March 31, 2013 and March 31, 2012, respectively. These amounts are primarily a result of changes in metal prices and changes in inventory volumes. The excess of current cost over the stated LIFO value of inventory at March 31, 2013 and December 31, 2012 was $20.8 and $24.5, respectively. Other inventories, principally operating supplies and repair and maintenance parts, are stated at average cost. Inventory costs consist of material, labor and manufacturing overhead, including depreciation. Abnormal costs, such as idle facility expenses, freight, handling costs and spoilage, are accounted for as current period charges. All of the Company’s inventories at March 31, 2013 and December 31, 2012 were included in the Fabricated Products segment (see Note 2 for the components of inventories).

Property, Plant, and Equipment – Net. Property, plant and equipment is recorded at cost (see Note 2). Construction in progress is included within Property, plant, and equipment – net on the Consolidated Balance Sheets. Interest related to the construction of qualifying assets is capitalized as part of the construction costs. The aggregate amount of interest capitalized is limited to the interest expense incurred in the period. The amount of interest expense capitalized as construction in progress was $0.4 and $0.6 during the quarters ended March 31, 2013 and March 31, 2012, respectively.

Depreciation is computed using the straight-line method at rates based on the estimated useful lives of the various classes of assets. Capital lease assets and leasehold improvements are depreciated on a straight-line basis over the shorter of the estimated useful lives of the assets or the lease term. Depreciation expense is not included in Cost of products sold, excluding depreciation and amortization, but is included in Depreciation and amortization on the Statements of Consolidated Income. For the quarters ended March 31, 2013 and March 31, 2012, the Company recorded depreciation expense of $6.5 and $5.8, respectively, relating to the Company’s operating facilities in its Fabricated Products segment. An immaterial amount of depreciation expense was also recorded relating to the Company’s Corporate and Other business unit for all periods presented in this Report.

New Accounting Pronouncements.

Accounting Standards Update (“ASU”) No. 2013-01, Balance Sheet (Topic 210): Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities (“ASU 2013-01”), was issued in January 2013. ASU 2013-01 clarifies that ordinary trade receivables and receivables are not in the scope of ASU No. 2011-11, Balance Sheet (Topic 210): Disclosures about Offsetting Assets and Liabilities (“ ASU 2011-11”). Specifically, ASU 2011-11 applies only to derivatives, repurchase agreements and

reverse purchase agreements, and securities borrowing and securities lending transactions that are either offset in accordance with specific criteria contained in the FASB Accounting Standards Codification or subject to a master netting arrangement or similar agreement. The Company is required to apply the amendments in ASU 2013-01 beginning first quarter of 2013. The adoption of ASU 2013-01 by the Company did not have a material impact on the consolidated financial statements.

ASU No. 2013-02, Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income (”ASU 2013-02”), was issued in February 2013. This ASU does not change the current requirements for reporting net income or other comprehensive income in financial statements. However, ASU 2013-02 requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required under GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts that are not required under GAAP to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures required under GAAP that provide additional detail about those amounts. The adoption of ASU 2013-02 by the Company in the first quarter of 2013 did not have a material impact on the consolidated financial statements.

Senior Notes

On May 23, 2012, the Company issued $225.0 principal amount of 8.250% Senior Notes due June 1, 2020 (the “Senior Notes”) at par. Interest expense, including amortization of deferred financing costs, relating to the Senior Notes was $4.8 for the quarter ended March 31, 2013. See Note 3 of Notes to Consolidated Financial Statements included in Part II, Item 8. “Financial Statements and Supplementary Data” in the Company’s Annual Report Form 10-K for the year ended December 31, 2012 for additional information regarding the Senior Notes.

Cash Convertible Senior Notes

Convertible Notes. In March 2010, the Company issued $175.0 principal amount of 4.5% Cash Convertible Senior Notes due April 1, 2015 (the “Convertible Notes”). The Convertible Notes are not convertible into the Company's common stock or any other securities, but instead will be settled in cash. The Company accounts for the cash conversion feature of the Convertible Notes as a separate derivative instrument (the “Bifurcated Conversion Feature”) with the fair value on the issuance date equaling the original issue discount for purposes of accounting for the debt component of the Convertible Notes. The following tables provide additional information regarding the Convertible Notes:

Principal amount	$	175.0		$	175.0
Less: unamortized issuance discount	(17.7		)	(19.7		)

____________


¹	A portion of the interest relating to the Convertible Notes is capitalized as Construction in progress.

Holders may convert their Convertible Notes at any time on or after January 1, 2015. The Convertible Notes’ conversion rate is subject to adjustment based on the occurrence of certain events. As of March 31, 2013, the conversion rate was 20.7309 shares per $1,000 principal amount of the Convertible Notes and the equivalent conversion price was approximately $48.24 per share, reflecting cumulative adjustments for quarterly dividends paid in excess of $0.24 per share.

Convertible Note Hedge Transactions. In March 2010, the Company purchased cash settled call options (the “Call Options”) that have an exercise price equal to the conversion price of the Convertible Notes and an expiration date that is the same as the maturity or earlier conversion date of the Convertible Notes. If the Company exercises the Call Options, the aggregate amount of cash it would receive from the counterparties to the Call Options would equal the aggregate amount of cash that the Company would be required to pay to the holders of the converted Convertible Notes, less the principal amount thereof. Contemporaneous with the purchase of the Call Options, the Company also sold net-share-settled warrants (the “Warrants”) with an exercise date of July 1, 2015 relating to approximately 3.6 million shares of the Company’s common stock. At March 31, 2013, the exercise prices were $48.24 per share and $61.25 per share for the Call Options and the Warrants, respectively, reflecting cumulative adjustments for quarterly dividends paid in excess of $0.24 per share.

Revolving Credit Facility

The Company’s credit agreement with JPMorgan Chase Bank, N.A., as administrative agent, and the other financial institutions party thereto (the “Revolving Credit Facility”) provides the Company with a $300.0 funding commitment through September 30, 2016. The Company had $286.0 of borrowing availability under the Revolving Credit Facility at March 31, 2013, based on the borrowing base determination then in effect. At March 31, 2013, there were no borrowings under the Revolving Credit Facility and $6.9 was being used to support outstanding letters of credit, leaving $279.1 of net borrowing availability. The interest rate applicable to any overnight borrowings under the Revolving Credit Facility would have been 4.0% at March 31, 2013.

See Note 4 of Notes to Consolidated Financial Statements included in Part II, Item 8. “Financial Statements and Supplementary Data” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012 for additional information regarding the Revolving Credit Facility.

4. Income Tax Matters

Tax Provision. The provision for incomes taxes, for each period presented, consisted of the following:



	Quarter Ended
	March 31,
	2013			2012
Domestic	$	15.4		$	15.6
Foreign	(7.2		)	0.7
Total	$	8.2		$	16.3

The income tax provision for the quarters ended March 31, 2013 and March 31, 2012 was $8.2 and $16.3, reflecting an effective tax rate of 19.7% and 38.1%, respectively. The difference between the effective tax rate and the projected blended statutory tax rate for the quarter ended March 31, 2013 was the result of a decrease in unrecognized tax benefits, including interest and penalties, of $7.5, resulting in a 17.9% decrease in the effective tax rate. The decrease in unrecognized tax benefits was a result of an audit settlement with the Canada Revenue Agency Competent Authority on February 28, 2013 for the 1998-2004 tax years. As a result of the settlement, a refund of $7.9 which represents amounts previously paid against the accrued tax reserve is expected. Such amount was included in Other receivables at March 31, 2013. The difference between the effective tax rate and the projected blended statutory tax rate for the quarter ended March 31, 2012 was primarily the result of an increase in unrecognized tax benefits, including interest and penalties, of $0.1, resulting in a 0.3% increase in the effective tax rate.

The Company’s gross unrecognized benefits relating to uncertain tax positions were $8.8 and $15.7 at March 31, 2013 and December 31, 2012, respectively, of which, $7.7 and $14.6 would impact the effective tax rate at March 31, 2013 and December 31, 2012, respectively, if and when the gross unrecognized tax benefits are recognized.

The Company expects its gross unrecognized tax benefits to be reduced by $3.5 within the next 12 months.

See Note 7 of Notes to Consolidated Financial Statements included in Part II, Item 8. “Financial Statements and Supplementary Data” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012 for additional information regarding income taxes.

5. Employee Benefits

Pension and Similar Benefit Plans. The Company has provided contributions to (i) multi-employer pension plans sponsored by the United Steel, Paper and Foresting, Rubber, Manufacturing, Energy, Allied Industrial and Service Workers International Union AFL-CIO, CLC (“USW”) and International Association of Machinists and certain other unions at certain of the Company’s production facilities, (ii) defined contribution 401(k) savings plans for hourly bargaining unit employees and

NOTES TO INTERIM CONSOLIDATED FINANCIAL STATEMENTS

(In millions of dollars, except share and per share amounts and as otherwise indicated)

salaried and certain hourly non-bargaining unit employees, (iii) a defined benefit plan for salaried employees at the Company’s London, Ontario facility, and (iv) a non-qualified, unfunded, unsecured plan of deferred compensation for key employees who would otherwise suffer a loss of benefits under the Company’s defined contribution plan. See Note 8 and Note 9 of Notes to Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012 for additional information with respect to the Company’s benefit plans.

VEBA Postretirement Medical Obligations. Certain retirees receive medical coverage through participation in a voluntary employee’s beneficiary association (“VEBA”) for the benefit of certain union retirees, their surviving spouses and eligible dependents (the “Union VEBA”) or a VEBA that provides benefits for certain other eligible retirees, their surviving spouse and eligible dependents (the “Salaried VEBA” and, together with the Union VEBA, the “VEBAs”). The Union VEBA is managed by four trustees, two of which are appointed by the Company. Its assets are managed by an independent fiduciary. The Salaried VEBA is managed by trustees who are independent of the Company.

The Company has no claim to the plan assets of the VEBAs nor obligation to fund the liability. The benefits paid by the VEBAs are at the sole discretion of the respective VEBA trustees and are outside the Company's control. The Company’s only financial obligations to the VEBAs are (i) to make an annual variable cash contribution (described below) and (ii) to pay up to $0.3 of the annual administrative expenses of the VEBAs. Nevertheless, the Company accounts for the VEBAs as defined benefit postretirement plans with the current VEBA assets and future variable contributions from the Company, and earnings thereon, operating as a cap on the benefits to be paid.

Under this accounting treatment, the funding status of the VEBAs could result in a liability or asset position on the Company's Consolidated Balance Sheets, but such liability or asset has no impact on the Company's cash flow or liquidity. Only the Company's obligation to make an annual variable cash contribution can have a material impact to the Company's cash flow or liquidity. The formula determining the annual variable contribution amount is 10% of the first $20.0 of annual cash flow (as defined; in general terms, the principal elements of cash flow are earnings before interest expense, provision for income taxes, and depreciation and amortization less cash payments for, among other things, interest, income taxes, and capital expenditures), plus 20% of annual cash flow, as defined, in excess of $20.0. Such payments may not exceed $20.0 annually, and payments are allocated between the Union VEBA and the Salaried VEBA at 85.5% and 14.5%, respectively. Amounts owing by the Company to the VEBAs are recorded on the Company’s Consolidated Balance Sheets under Other accrued liabilities (until paid in cash), with a corresponding increase in Net assets in respect of VEBA, a decrease in Net liability in respect of VEBA, or a combination thereof. The variable contributions with respect to 2012 totaled the maximum of $20.0 and were paid during the first quarter of 2013.

Components of Net Periodic Pension Benefit (Income) Cost. The Company’s results of operations included the following impacts associated with the Canadian defined benefit plan and the VEBAs: (a) charges for service rendered by employees; (b) a charge for accretion of interest; (c) a benefit for the return on plan assets; and (d) amortization of net gains or losses on assets, prior service costs associated with plan amendments and actuarial differences. Net periodic pension benefit cost related to the Canadian defined benefit plan was not material for the quarters ended March 31, 2013 and March 31, 2012. The following table presents the components of net periodic pension benefit income for the VEBAs and charges relating to all other employee benefit plans for the quarters ended March 31, 2013 and March 31, 2012:



	Quarter Ended

For all periods presented, the net periodic pension benefit income relating to the VEBAs are included as a component of Selling, administrative, research and development and general expense within All Other. Further, substantially all of the Fabricated Products segment’s employee benefits related charges are in Cost of products sold, excluding depreciation and amortization and other items with the balance in Selling, administrative, research and development, and general.

See Note 8 of Notes to Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012 for additional information with respect to the VEBAs and key assumptions used with respect to the Company’s pension plans and key assumptions made in computing the net obligation of each VEBA.

6. Employee Incentive Plans

Short-term Incentive Plans (“STI Plans”)

The Company has a short-term incentive compensation plan for senior management and certain other employees payable at the Company’s election in cash, shares of common stock, or a combination of cash and shares of common stock. Amounts earned under the plan are based primarily on economic value added (“EVA”) of the Company’s Fabricated Products business, adjusted for certain safety and performance factors. EVA, as defined by the Company’s STI Plans, is a measure of the excess of the Company’s adjusted pre-tax operating income for a particular year over a pre-determined percentage of the adjusted net assets of the immediately preceding year, measured over a one-year period. Most of the Company’s production facilities have similar programs for both hourly and salaried employees.

Total costs relating to STI Plans were recorded as follows, for each period presented:



	Quarter Ended
	March 31,
	2013		2012
Cost of products sold, excluding depreciation and amortization and other items	$	1.1	$	1.2
Selling, administrative, research and development, and general	3.0		2.7
Total costs recorded in connection with STI Plans	$	4.1	$	3.9

The following table presents the allocation of the charges detailed above, by segment:

Fabricated Products	$	2.9	$	2.7
All Other	1.2		1.2
Total costs recorded in connection with STI Plans	$	4.1	$	3.9

Long-term Incentive Programs (”LTI Programs”)

General. Officers and other key employees of the Company or one or more of its subsidiaries, as well as directors of the Company, are eligible to participate in the Kaiser Aluminum Corporation 2006 Equity and Performance Incentive Plan (as amended, the “Equity Incentive Plan”). Subject to certain adjustments that may be required from time to time to prevent dilution or enlargement of the rights of participants under the Equity Incentive Plan, a total of 2,722,222 common shares have been authorized for issuance under the Equity Incentive Plan. At March 31, 2013, 865,562 common shares were available for additional awards under the Equity Incentive Plan.

Non-vested Common Shares, Restricted Stock Units and Performance Shares. The Company grants non-vested common shares to its non-employee directors, executive officers and other key employees. The Company also grants restricted stock

Table of Contents

KAISER ALUMINUM CORPORATION AND SUBSIDIARY COMPANIES

NOTES TO INTERIM CONSOLIDATED FINANCIAL STATEMENTS

(In millions of dollars, except share and per share amounts and as otherwise indicated)

units to certain employees. The restricted stock units have rights similar to the rights of non-vested common shares, and the employee will receive one common share for each restricted stock unit upon the vesting of the restricted stock unit. In addition to non-vested common shares and restricted stock units, the Company also grants performance shares to executive officers and other key employees. Such awards are subject to performance requirements pertaining to the Company’s EVA performance (as set forth in each year’s LTI Program), measured over the applicable three-year performance period. EVA is a measure of the excess of the Company’s adjusted pre-tax operating income for a particular year over a pre-determined percentage of the adjusted net assets of the immediately preceding year. The number of performance shares, if any, that will ultimately vest and result in the issuance of common shares depends on the average annual EVA achieved for the specified three-year performance periods.

See Note 10 of Notes to Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012 for additional information with respect to the Equity Incentive Plan and the detailed vesting requirements for the different types of equity awards described above.

Non-cash Compensation Expense. Compensation expense relating to all awards under the Equity Incentive Plan are included in Selling, administrative, research and development, and general. Recorded non-cash compensation expense by type of award under LTI Programs were as follows, for each period presented:

A summary of select activity with respect to non-vested common shares, restricted stock units and performance shares for the quarter ended March 31, 2012 is as follows:



	Non-Vested Common Shares				Restricted Stock Units				Performance Shares
	Shares		Weighted-Average Grant-Date Fair Value per Share		Units		Weighted-Average Grant-Date Fair Value per Unit		Shares		Weighted-Average Grant-Date Fair Value per Share
Granted	72,859		$	44.46	2,486		$	44.46	211,900		$	44.46
Vested	(119,413	)	$	21.09	(3,375	)	$	25.77	(7,952	)	$	18.89

Stock Options. The Company has fully-vested stock options from a one-time issuance in 2007. As of both March 31, 2013 and December 31, 2012, 20,791 fully-vested options were outstanding, in each case exercisable to purchase common shares at $80.01 per share and having a remaining contractual life of 4.0 and 4.25 years, respectively. The average fair value of the options granted was $39.90. No new options were granted and no existing options were forfeited or exercised during the quarter ended March 31, 2013.

Vested Stock. From time to time, the Company issues common shares to non-employee directors electing to receive common shares in lieu of all or a portion of their annual retainer fees. The fair value of these common shares is based on the fair value of the shares at the date of issuance and is immediately recognized in earnings as a period expense. Such shares are generally issued during the second quarter of each fiscal year.

Under the Equity Incentive Plan, participants may elect to have the Company withhold common shares to satisfy minimum statutory tax withholding obligations arising in connection with the exercise of stock options and vesting of non-vested shares, restricted stock units and performance shares. Any such shares withheld are canceled by the Company on the applicable vesting dates, which correspond to the times at which income to the employee is recognized. When the Company withholds these common shares, the Company is required to remit to the appropriate taxing authorities the fair value of the shares withheld as of the vesting date. During the quarters ended March 31, 2013 and March 31, 2012, 35,838 and 45,128 common shares, respectively, were withheld and canceled for this purpose.

7. Commitments and Contingencies

Commitments. The Company has a variety of financial commitments, including purchase agreements, forward foreign exchange and forward sales contracts, indebtedness (and related Call Options and Warrants) and letters of credit (see Note 3 and Note 8).

Table of Contents

KAISER ALUMINUM CORPORATION AND SUBSIDIARY COMPANIES

NOTES TO INTERIM CONSOLIDATED FINANCIAL STATEMENTS

(In millions of dollars, except share and per share amounts and as otherwise indicated)

Refer to Note 11 of Notes to Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012 for information relating to minimum rental commitments under operating leases. There have been no material changes to such scheduled rental commitments as of the filing of this Report.

Environmental Contingencies. The Company is subject to a number of environmental laws and regulations, to potential fines or penalties assessed for alleged breaches of the environmental laws and regulations, and to potential claims based upon such laws and regulations.

The Company has established procedures for regularly evaluating environmental loss contingencies. The Company’s environmental accruals represent the Company’s undiscounted estimate of costs reasonably expected to be incurred based on presently enacted laws and regulations, existing requirements, currently available facts, existing technology, and the Company’s assessment of the likely remediation actions to be taken.

The Company submitted a final feasibility study, after public comment and agency review, to the Washington State Department of Ecology (“Washington State Ecology”) which included recommendations for remediation alternatives to primarily address the historical use of oils containing polychlorinated biphenyls, or PCBs, at the Company’s Trentwood facility in Spokane, Washington. During the third quarter of 2012, Washington State Ecology and the Company signed an amended work order allowing certain remediation activities to begin and to initiate a treatability study in regards to proposed PCB remediation methods. The Company continues to work with Washington State Ecology in developing the implementation work plans, which are subject to Washington State Ecology approval. The Company expects to begin implementation of approved work plans sometime in 2013.

At March 31, 2013, the Company’s environmental accrual of $22.0 represented the Company’s best estimate of the incremental cost based on proposed alternatives in the final feasibility study related to the Company’s Trentwood facility in Spokane, Washington and on investigational studies and other remediation activities occurring at certain other locations owned by the Company. The Company expects that these remediation actions will be taken over the next 30 years.

As additional facts are developed, feasibility studies are completed, draft remediation plans are modified, necessary regulatory approvals for the implementation of remediation are obtained, alternative technologies are developed, and/or other factors change, there may be revisions to management’s estimates, and actual costs may exceed the current environmental accruals. The Company believes at this time that it is reasonably possible that undiscounted costs associated with these environmental matters may exceed current accruals by amounts that could be, in the aggregate, up to an estimated $19.1 over the next 30 years. It is reasonably possible that the Company’s recorded estimate may change in the next 12 months.

Other Contingencies. The Company is party to various lawsuits, claims, investigations, and administrative proceedings that arise in connection with past and current operations. The Company evaluates such matters on a case-by-case basis, and its policy is to vigorously contest any such claims it believes are without merit. The Company accrues for a legal liability when it is both probable that a liability has been incurred and the amount of the loss is reasonably estimable. Quarterly, in addition to when changes in facts and circumstances require it, the Company reviews and adjusts these accruals to reflect the impacts of negotiations, settlements, rulings, advice of legal counsel and other information, and events pertaining to a particular case. While uncertainties are inherent in the final outcome of such matters and it is presently impossible to determine the actual cost that may ultimately be incurred, management believes that it has sufficiently reserved for such matters and that the ultimate resolution of pending matters will not have a material adverse impact on its consolidated financial position, operating results, or liquidity.

8. Derivative Financial Instruments and Related Hedging Programs

Overview. In conducting its business, the Company, from time to time, enters into derivative transactions, including forward contracts and options, to limit its economic (i.e., cash) exposure resulting from (i) metal price risk related to its sale of fabricated aluminum products and the purchase of metal used as raw material for its fabrication operations, (ii) energy price risk relating to fluctuating prices of natural gas and electricity used in its production processes, and (iii) foreign currency requirements with respect to its foreign subsidiaries, investment and cash commitments for equipment purchases. Additionally, in connection with the issuance of the Convertible Notes, the Company purchased cash-settled Call Options relating to the Company’s common stock to limit its exposure to the cash conversion feature of the Convertible Notes (see Note 3).

Hedges of Operational Risks. The Company’s pricing of fabricated aluminum products is generally intended to lock in a conversion margin (representing the value added from the fabrication process(es)) and to pass metal price fluctuations to its customers. However, in certain instances the Company enters into firm-price arrangements with its customers and incurs price risk on its anticipated aluminum purchases in respect of such customer orders. The Company uses third-party hedging instruments to limit exposure to metal price risks related to firm-price customer sales contracts. See Note 9 for additional

Table of Contents

KAISER ALUMINUM CORPORATION AND SUBSIDIARY COMPANIES

NOTES TO INTERIM CONSOLIDATED FINANCIAL STATEMENTS

(In millions of dollars, except share and per share amounts and as otherwise indicated)

information regarding the Company’s material derivative positions relating to hedges of operational risks, and their respective fair values.

A majority of the Company's derivative contracts relating to hedges of operational risks contain credit risk-related contingencies. The Company regularly reviews the creditworthiness of its derivative counterparties and does not expect to incur significant loss from the failure of any counterparties to perform under any agreements. To minimize the potential of posting margin related to our liability hedge positions, the Company allocates hedging transactions among its counterparties, uses options as part of the hedging activities, or both. The aggregate fair value of derivative instruments that contain credit-risk-related contingent features that were in a net liability position at March 31, 2013 was $2.8.

During the quarters ended March 31, 2013 and March 31, 2012, total fabricated products shipments that contained fixed price terms were (in millions of pounds) 29.8 and 46.1, respectively. At March 31, 2013, the Fabricated Products segment held contracts for the delivery of fabricated aluminum products that had the effect of creating price risk on anticipated purchases of aluminum for the remainder of 2013, 2014 and 2015 and thereafter, totaling approximately (in millions of pounds) 58.6, 2.5 and 1.3, respectively.

Hedges Relating to the Convertible Notes. As described in Note 3, the Company issued Convertible Notes in the aggregate principal amount of $175.0 in March 2010. The conversion feature of the Convertible Notes can only be settled in cash and is required to be bifurcated from the Convertible Notes and treated as a separate derivative instrument. In order to offset the cash flow risk associated with the Bifurcated Conversion Feature, the Company purchased Call Options, which are accounted for as derivative instruments. The Company expects that the realized gain or loss from the Call Options will substantially offset the realized loss or gain of the Bifurcated Conversion Feature upon maturity of the Convertible Notes. However, because valuation assumptions for the Bifurcated Conversion Feature and the Call Option are not identical, over time the Company expects to record net unrealized gains and losses due to mark-to-market adjustments to the fair values of the two derivatives. See Note 9 for additional information regarding the fair values of the Bifurcated Conversion Feature and the Call Options.

Realized and Unrealized Gains and Losses. Realized and unrealized (losses) gains associated with all derivative contracts consisted of the following, for each period presented:

¹	Regional premiums represent the premium over the London Metal Exchange price for primary aluminum which is incurred on the Company’s purchases of primary aluminum.


²	As of March 31, 2013, the Company’s exposure to fluctuations in natural gas prices had been substantially reduced for approximately 88%, 83% and 48% of the expected natural gas purchases for the remainder of 2013, 2014 and 2015, respectively.

The Bifurcated Conversion Feature represents the cash conversion feature of the Convertible Notes. The Call Options expire on the maturity of the Convertible Notes and have an exercise price equal to the conversion price of the Convertible Notes, subject to anti-dilution adjustments substantially similar to the anti-dilution adjustments for the Convertible Notes. Although the fair value of the Call Options is derived from a notional number of shares of the Company’s common stock, the Call Options may only be settled in cash.

9. Fair Value Measurements

Overview

The Company applies the fair value hierarchy established by GAAP for the recognition and measurement of assets and liabilities. An asset or liability’s fair value classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement. In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible, and considers counterparty risk in its assessment of fair value.

The fair values of financial assets and liabilities are measured on a recurring basis. The Company has elected not to carry any financial assets and liabilities at fair value, other than as required by GAAP. Financial assets and liabilities that the Company carries at fair value, as required by GAAP include: (i) its derivative instruments, (ii) the plan assets of the VEBAs and the Company’s Canadian defined benefit pension plan, and (iii) available for sale securities, consisting of commercial

(In millions of dollars, except share and per share amounts and as otherwise indicated)

paper and investments related to the Company’s deferred compensation plan (see Note 5). The Company records certain other financial assets and liabilities at carrying value (see the tables below for the fair value disclosure of those assets and liabilities).

The majority of the Company’s non-financial assets and liabilities, which include goodwill, intangible assets, inventories and property, plant, and equipment, are not required to be carried at fair value on a recurring basis. However, if certain triggering events occur (or at least annually for goodwill), an evaluation of a non-financial asset or liability is required, potentially resulting in an adjustment to the carrying amount of such asset or liability. For the three months ended March 31, 2013 and March 31, 2012, the Company concluded that none of its non-financial assets and liabilities subject to fair value assessments on a non-recurring basis required a material adjustment to the carrying amount of such assets and liabilities.

Fair Values of Financial Assets and Liabilities

Fair Values of Derivative Assets and Liabilities. The Company’s derivative contracts are valued at fair value using significant observable and unobservable inputs.

Commodity, Foreign Currency and Energy Hedges - The fair values of a majority of these derivative contracts are based upon trades in liquid markets. Valuation model inputs can generally be verified, and valuation techniques do not involve significant judgment. The Company has some derivative contracts, however, that do not have observable market quotes. For these financial instruments, management uses significant other observable inputs (e.g., information concerning regional premiums for swaps). Where appropriate, valuations are adjusted for various factors, such as bid/offer spreads.

Bifurcated Conversion Feature and Call Options - The fair value of the Bifurcated Conversion Feature is measured as the difference in the estimated fair value of the Convertible Notes and the estimated fair value of the Convertible Notes without the cash conversion feature. The Convertible Notes are valued based on the trading price of the Convertible Notes each period-end (see “All Other Financial Assets and Liabilities” below). The fair value of the Convertible Notes without the cash conversion feature is the present value of the series of the remaining fixed income cash flows under the Convertible Notes, with a mandatory redemption in 2015.

The Company determines the fair value of the Call Options using a binomial lattice valuation model. The inputs to the model at March 31, 2013 were as follows:



The Company’s stock price at March 31, 2013	$	64.65
Quarterly dividend yield (per share) upon purchase of the Call Option¹	$	0.24
Risk-free interest rate²	0.25		%
Credit spread (basis points)³	220
Expected volatility rate⁴	17.2		%

______________________


¹	The quarterly dividend in the first quarter of 2013 was $0.30 per share, but the model assumes a $0.24 per share quarterly dividend as was paid at the inception of the Call Options. Quarterly dividends in excess of $0.24 per share do not affect the Call Options’ value due to anti-dilution adjustments.


²	The risk-free rate was based on the 2-year Constant Maturity Treasury rate on March 31, 2013.


³	The credit spread is based on the Company’s long-term credit rating of BB- issued by Standard & Poor’s and a senior unsecured credit rating of Ba3 issued by Moody’s.


⁴	The volatility rate was based on both observed volatility, which is based on the Company’s historical stock price, and implied volatility from the Company’s traded options. Such volatility was further adjusted to take into consideration market participant risk tolerance.

VEBA and Canadian Pension Plan Assets. The fair value of the plan assets of the VEBAs and the Company’s Canadian pension plan is measured annually on December 31. In determining the fair value of the plan assets at each annual period end, the Company utilizes primarily the results of valuations supplied by the investment advisors responsible for managing the assets of each plan. See Note 13 of Notes to Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012 for additional information with respect to the fair value of the plan assets of the VEBAs and the Company’s Canadian pension plan.

Available for sale securities. The Company holds assets in various investment funds at certain registered investment companies in connection with its deferred compensation program (see Note 5). Such assets are accounted for as available for sale securities and are measured and recorded at fair value based on the net asset value of the investment funds on a recurring

(In millions of dollars, except share and per share amounts and as otherwise indicated)

basis. Such fair value input is considered either a Level 1 or Level 2 input depending on whether the investment fund is traded on a public exchange. In addition to investment funds, the Company also holds short-term commercial paper. The fair value of the commercial paper is determined based on valuation models that use observable market data. Such fair value input is considered a Level 2 input. The amortized cost for available for sale securities approximates its fair value. At March 31, 2013, the remaining maturity period with respect to commercial paper ranges from 10 days to approximately 5 months.

All Other Financial Assets and Liabilities. The Company believes that the fair value of its cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities approximate their respective carrying values due to their short maturities and nominal credit risk.

The fair value of the Convertible Notes and Senior Notes are based on the trading prices of the notes and are considered a Level 1 input in the fair value hierarchy (see Note 3 for the carrying value of the Convertible Notes and the Senior Notes).

During the quarters ended March 31, 2013 and March 31, 2012, the Company paid approximately $5.9 ($0.30 per common share) and $4.9 ($0.25 per common share), respectively, in cash dividends to stockholders, including the holders of restricted stock, and dividend equivalents to the holders of restricted stock units and to the holders of performance shares with respect to approximately one-half of the performance shares.

At March 31, 2013 and December 31, 2012, $30.7 and $46.9, respectively, were available for repurchases of the Company’s common shares under an outstanding stock repurchase authorization by the Company’s Board of Directors. The Company repurchased 259,596 shares of common stock at a weighted-average price of $62.62 per share pursuant to this authorization during the quarter ended March 31, 2013. The total cost of $16.2 was recorded as Treasury Stock.

11. Segment and Geographical Area Information

The Company’s primary line of business is the production of semi-fabricated specialty aluminum products, such as aluminum sheet and plate and extruded and drawn products, primarily used in aerospace/high strength, general engineering, automotive, and other industrial end market applications. The Company operates 11 focused production facilities in the United States and one in Canada. Consistent with the manner in which the Company’s chief operating decision maker reviews and evaluates the Company’s business, the Fabricated Products business is treated as a single operating segment.

In addition to the Fabricated Products segment, the Company has two business units, Secondary Aluminum and Corporate and Other. The Secondary Aluminum business unit sells value added products, such as ingot and billet, produced at Anglesey Aluminium Limited (“Anglesey”), a secondary aluminum remelt and casting facility in Holyhead, Wales in which the Company owns a 49% non-controlling interest. The Corporate and Other business unit provides general and administrative support for the Company’s operations.

For purposes of segment reporting under GAAP, the Company treats the Fabricated Products segment as a reportable segment and combines the two other business units, Secondary Aluminum and Corporate and Other, into one category, which is referred to as All Other. All Other is not considered a reportable segment.

The board of Anglesey recently announced the closure of Anglesey's secondary aluminum remelt and casting operations which the Company expects to be completed by the second quarter of 2013. The Company’s investment in Anglesey is valued at zero on the balance sheet, and the Company has no financial obligation with respect to any liability of Anglesey. Accordingly, the Company does not expect the closure of Anglesey's operations to have any financial impact. See Note 3 of Notes to Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2010 for additional details on our investment in Anglesey and the suspension of equity method of accounting with respect to our ownership in Anglesey.

The accounting policies of the Fabricated Products segment are the same as those described in Note 1. Segment results are evaluated internally by management before any allocation of corporate overhead and without any charge for income taxes, interest expense, or Other operating charges, net.
