INTERIM FINANCIAL STATEMENTS

Our interim condensed consolidated financial statements (unaudited) and Huntsman International's interim condensed consolidated financial statements (unaudited) were prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP" or "U.S. GAAP") and in management's opinion reflect all adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation of results of operations, comprehensive income, financial position and cash flows for the periods presented. Results for interim periods are not necessarily indicative of those to be expected for the full year. These condensed consolidated financial statements (unaudited) should be read in conjunction with the audited consolidated financial statements and notes to consolidated financial statements included in the Annual Report on Form 10-K for the year ended December 31, 2012 for our Company and Huntsman International.

DESCRIPTION OF BUSINESS

We are a global manufacturer of differentiated organic chemical products and of inorganic chemical products. Our products comprise a broad range of chemicals and formulations, which we market globally to a diversified group of consumer and industrial customers. Our products are used in a wide range of applications, including those in the adhesives, aerospace, automotive, construction products, personal care and hygiene, durable and non-durable consumer products, electronics, medical, packaging, paints and coatings, power generation, refining, synthetic fiber, textile chemicals and dye industries. We are a leading global producer in many of our key product lines, including MDI, amines, surfactants, maleic anhydride, epoxy- based polymer formulations, textile chemicals, dyes and titanium dioxide.

We operate in five segments: Polyurethanes, Performance Products, Advanced Materials, Textile Effects and Pigments. Our Polyurethanes, Performance Products, Advanced Materials and Textile Effects segments produce differentiated organic chemical products and our Pigments segment produces inorganic chemical products. In a series of transactions beginning in 2006, we sold or shutdown substantially all of our Australian styrenics operations and our North American polymers and base chemicals operations. We report the results of these businesses as discontinued operations.

COMPANY

Our Company, a Delaware corporation, was formed in 2004 to hold the Huntsman businesses. Jon M. Huntsman founded the predecessor to our Company in 1970 as a small packaging company. Since then, we have grown through a series of acquisitions and now own a global portfolio of businesses.

We operate all of our businesses through Huntsman International, our 100% owned subsidiary. Huntsman International is a Delaware limited liability company.

HUNTSMAN CORPORATION AND HUNTSMAN INTERNATIONAL FINANCIAL STATEMENTS

Except where otherwise indicated, these notes relate to the condensed consolidated financial statements (unaudited) for both our Company and Huntsman International. The differences between our financial statements and Huntsman International's financial statements relate primarily to the following:

•: purchase accounting recorded at our Company for the 2003 step-acquisition of Huntsman International Holdings LLC, the former parent company of Huntsman International that was merged into Huntsman International in 2005;
•: the different capital structures; and
•: a note payable from Huntsman International to us.

PRINCIPLES OF CONSOLIDATION

Our condensed consolidated financial statements (unaudited) include the accounts of our wholly-owned and majority-owned subsidiaries and any variable interest entities for which we are the primary beneficiary. All intercompany accounts and transactions have been eliminated, except for intercompany sales between continuing and discontinued operations.

USE OF ESTIMATES

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

RECENT DEVELOPMENTS

On April 29, 2013, Huntsman International entered into amendments to its U.S. accounts receivable securitization program ("U.S. A/R Program") and its European accounts receivable securitization program ("EU A/R Program" and, collectively with the U.S. A/R Program, our "A/R Programs"). These amendments, among other things, extend the scheduled commitment termination date of the loan facilities under our A/R Programs to April 2016. For more information, see "Note 7. Debt—Direct and Subsidiary Debt—Amendments to A/R Programs."

1. GENERAL (Continued)

On March 11, 2013, Huntsman International entered into an eighth amendment to its senior secured credit facilities (the "Senior Credit Facilities"). The amendment provided for an additional term loan of $225 million, the net proceeds of which were used to repay in full the remaining $193 million principal amount outstanding under our term loan B facility ("Term Loan B") and for general corporate purposes. We recognized a loss on early extinguishment of debt of approximately $1 million on this redemption. The additional term loan has identical terms to our existing extended term loan B facility ("Extended Term Loan B"). See "Note 7. Debt—Direct and Subsidiary Debt—Amendment to Credit Agreement."

On March 4, 2013, Huntsman International, pursuant to an indenture entered into on November 19, 2012, issued $250 million aggregate principal amount of additional 4.875% senior notes due 2020 (the "2020 Senior Notes"). Huntsman International applied the net proceeds to redeem the remaining $200 million in aggregate principal amount of its 5.50% senior notes due 2016 (the "2016 Senior Notes"), to pay associated accrued interest and for general corporate purposes. We recognized a loss on early extinguishment of debt of approximately $34 million on this redemption. For more information, see "Note 7. Debt—Direct and Subsidiary Debt—Notes."

2. RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

Accounting Pronouncements Adopted During 2013

In July 2012, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2012-02, Intangibles—Goodwill and Other (Topic 350): Testing Indefinite-Lived Intangible Assets for Impairment. The guidance in this ASU is intended to reduce complexity and costs of the annual impairment tests for indefinite-lived intangible assets by providing entities with the option of performing a qualitative assessment to determine whether further impairment testing is necessary. The amendments in this ASU include examples of events and circumstances that might indicate that an asset's fair value is less than its carrying value. The amendments in this ASU were effective prospectively for annual and interim indefinite-lived intangible assets impairment tests performed for fiscal years beginning after September 15, 2012. We adopted the amendments in this ASU effective January 1, 2013, and the initial adoption of the amendments in this ASU did not have a significant impact on our condensed consolidated financial statements (unaudited).

In February 2013, the FASB issued ASU No. 2013-02, Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income, requiring entities to disclose information about the amounts reclassified out of accumulated other comprehensive income by component, as well as report, either on the face of the income statement where net income is presented or in the notes, the effect of significant reclassifications out of accumulated other comprehensive income on the respective line items of net income. The amendments in this ASU were effective prospectively for interim and annual periods beginning after December 15, 2012. We adopted the amendments of this ASU effective January 1, 2013 and have disclosed the above additional

information about reclassifications out of accumulated other comprehensive (loss) income in the notes to our condensed consolidated financial statements (unaudited). See "Note 12. Other Comprehensive (Loss) Income."

Accounting Pronouncements Pending Adoption in Future Periods

In February 2013, the FASB issued ASU No. 2013-04, Liabilities (Topic 405): Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of the Obligation Is Fixed at the Reporting Date, requiring entities to measure obligations resulting from joint and several liability arrangements for which the total amount of the obligation is fixed at the reporting date, as the sum of the amount the reporting entity agreed to pay on the basis of its arrangement among its co-obligors and any additional amount the reporting entity expects to pay on behalf of its co-obligors. The amendments in this ASU are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. The amendments in this ASU should be applied retrospectively to all prior periods presented for those obligations resulting from joint and several liability arrangements that exist at the beginning of an entity's fiscal year of adoption. We do not expect the adoption of the amendments in this ASU to have a significant impact on our condensed consolidated financial statements (unaudited).

In March 2013, the FASB issued ASU No. 2013-05, Foreign Currency Matters (Topic 830): Parent's Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity, resolving diversity in practice and clarifying the applicable guidance for the release of the cumulative translation adjustment into net income when a parent either sells a part or all of its investment in a foreign entity or no longer holds a controlling financial interest in a subsidiary or group of assets that is a nonprofit activity or business within a foreign entity. The amendments in this ASU are effective prospectively for fiscal years, and interim periods within those years, beginning after December 15, 2013. We do not expect the adoption of the amendments in this ASU to have a significant impact on our condensed consolidated financial statements (unaudited).

3. BUSINESS COMBINATIONS

NIPPON AQUA EQUITY INVESTMENT

In March 2013, we completed the acquisition of a 20% equity interest in Nippon Aqua Co. Ltd. ("Nippon Aqua"), a spray polyurethane foam ("SPF") insulation company based in Yokohama, Japan. In addition, we entered into a 10 year supply agreement with the company. Nippon Aqua is the SPF market leader in Japan, with business operations in over 30 locations across the country, and is a subsidiary of leading residential home builder Hinokiya Holdings Co. Ltd. We supply various advanced MDI-based polyurethanes systems to Nippon Aqua. We will account for this investment using the equity method and will report the equity earnings in our Polyurethanes segment.

3. BUSINESS COMBINATIONS (Continued)

RUSSIAN MDI, COATINGS AND SYSTEMS ACQUISITION

On July 3, 2012, we completed our acquisition of the remaining 55% ownership interest in International Polyurethane Investments B.V. (the "Russian Systems House Acquisition"). This company's wholly owned subsidiary, Huntsman NMG ZAO, is a leading supplier of polyurethane systems to the adhesives, coatings and footwear markets in Russia, Ukraine and Belarus and is headquartered in Obninsk, Russia. The acquisition cost was approximately €13 million (approximately $16 million). The acquired business was integrated into our Polyurethanes segment. Transaction costs charged to expense related to this acquisition were not significant. The fair value of our existing 45% ownership interest immediately prior to the acquisition was $13 million, valued by applying the income approach. Key assumptions include a discount rate of 17% and a terminal growth rate of 4%. In connection with this transaction, during the third quarter of 2012 we recorded a noncash pretax loss of approximately $4 million in other operating (income) expense on the consolidation of this investment. The long-term debt of approximately $7 million that was assumed as part of this transaction was repaid shortly after the acquisition date.

We have accounted for the Russian Systems House Acquisition using the acquisition method. As such, we analyzed the fair value of tangible and intangible assets acquired and liabilities assumed. The preliminary allocation of acquisition cost to the assets acquired and liabilities assumed is summarized as follows (dollars in millions):


Fair value of original 45% ownership interest acquired in 2007	$	13
Acquisition cost of 55% ownership interest acquired in 2012		16

Total fair value of net assets acquired	$	29

Fair value of assets acquired and liabilities assumed:
Accounts receivable	$	2
Inventories		9
Other current assets		1
Property, plant and equipment		31
Accounts payable		(4	)
Accrued liabilities		(1	)
Deferred income taxes		(2	)
Long-term debt		(7	)

Total fair value of net assets acquired	$	29

The acquisition cost allocation is preliminary pending final determination of the fair value of assets acquired and liabilities assumed, including final valuation of working capital, property, plant and equipment, intangible assets and the determination of related deferred taxes. For purposes of this preliminary allocation of fair value, we have assigned any excess of the acquisition cost over historical carrying values to property, plant and equipment and no amounts have been allocated to goodwill. It is possible that changes to this preliminary allocation could occur.

3. BUSINESS COMBINATIONS (Continued)

If this acquisition were to have occurred January 1, 2012, there would have been no significant impact to combined earnings to our Company and Huntsman International. The following estimated pro forma revenues attributable to our Company and Huntsman International would have been reported (dollars in millions):

	Pro Forma

	Three months ended March 31, 2012 (unaudited)
Revenues	$	2,919

4. INVENTORIES

Inventories are stated at the lower of cost or market, with cost determined using last-in first-out ("LIFO"), first-in first-out, and average costs methods for different components of inventory. Inventories consisted of the following (dollars in millions):

	March 31, 2013			December 31, 2012

Raw materials and supplies	$	478		$	484
Work in progress		101			98
Finished goods		1,297			1,311

Total		1,876			1,893
LIFO reserves		(79	)		(74	)

Net	$	1,797		$	1,819

For both March 31, 2013 and December 31, 2012, approximately 11% of inventories were recorded using the LIFO cost method.

In the normal course of operations we, at times, exchange raw materials and finished goods with other companies for the purpose of reducing transportation costs. The net nonmonetary open exchange positions are valued at cost. The amounts included in inventory under nonmonetary open exchange agreements receivable by us for both March 31, 2013 and December 31, 2012 was $6 million. Other open exchanges are settled in cash and result in a net deferred profit margin. The amounts payable under these open exchange agreements as of March 31, 2013 and December 31, 2012 were $2 million and nil, respectively.

5. VARIABLE INTEREST ENTITIES

We evaluate our investments and transactions to identify variable interest entities for which we are the primary beneficiary. We hold a variable interest in the following four joint ventures for which we are the primary beneficiary:

•: Rubicon LLC manufactures products for our Polyurethanes and Performance Products segments. The structure of the joint venture is such that the total equity investment at risk is not sufficient to permit the joint venture to finance its activities without additional financial support. By virtue of the operating agreement with this joint venture, we purchase a majority of the output, absorb a majority of the operating costs and provide a majority of the additional funding.
•: Pacific Iron Products Sdn Bhd manufactures products for our Pigments segment. In this joint venture we supply all the raw materials through a fixed cost supply contract, operate the manufacturing facility and market the products of the joint venture to customers. Through a fixed price raw materials supply contract with the joint venture we are exposed to the risk related to the fluctuation of raw material pricing.
•: Arabian Amines Company manufactures products for our Performance Products segment. Prior to July 1, 2010, this joint venture was in the development stage and the total equity investment at risk was sufficient for the joint venture to finance its activities without additional support. Therefore, Arabian Amines Company was accounted for under the equity method. In July 2010, Arabian Amines Company exited the development stage, which triggered the reconsideration of Arabian Amines Company as a variable interest entity. As required in the operating agreement governing this joint venture, we purchase all of Arabian Amines Company's production and sell it to our customers. Substantially all of the joint venture's activities are conducted on our behalf. Accordingly, we concluded that we were the primary beneficiary and began consolidating Arabian Amines Company beginning July 1, 2010.
•: Sasol-Huntsman is our 50%-owned joint venture with Sasol that owns and operates a maleic anhydride facility in Moers, Germany. This joint venture manufactures products for our Performance Products segment. Prior to April 1, 2011, we accounted for Sasol-Huntsman using the equity method. In April 2011, an expansion at this facility began production, which triggered the reconsideration of this joint venture as a variable interest entity. The joint venture uses our technology and expertise, and we bear a disproportionate amount of risk of loss due to a related-party loan to Sasol-Huntsman for which we bear the default risk. As a result, we concluded that we were the primary beneficiary and began consolidating Sasol-Huntsman beginning April 1, 2011.

Creditors of these entities have no recourse to our general credit, except in the event that we offer guarantees of specified indebtedness. See "Note 7. Debt—Direct and Subsidiary Debt." As the primary beneficiary of these variable interest entities at March 31, 2013, the joint ventures' assets, liabilities and results of operations are included in our condensed consolidated financial statements (unaudited).

We expect to incur additional charges of $65 million through March 2014, also related to this initiative.

2012 RESTRUCTURING ACTIVITIES

During the three months ended March 31, 2012, our Polyurethanes segment recorded charges of $5 million primarily related to cost reduction programs.

During the three months ended March 31, 2012, our Advanced Materials segment recorded charges of $1 million primarily related to the reorganization of our global business structure and the relocation of our divisional headquarters from Basel, Switzerland to The Woodlands, Texas.

On September 27, 2011, we announced plans to implement a significant restructuring of our Textile Effects segment, including the closure of our production facilities and business support offices in Basel, Switzerland, as part of an ongoing strategic program aimed at improving the Textile Effects segment's long-term global competitiveness. In connection with this plan, during the first quarter of 2012, we recorded a charge of $1 million primarily for workforce reductions. In addition, during the three months ended March 31, 2012, our Textile Effects segment recorded charges of $3 million primarily related to the closure of our St. Fons, France facility and a global transfer pricing initiative. Also during the three months ended March 31, 2012, we reversed $12 million of reserves that were no longer required for workforce reductions at our production facility in Langweid, Germany, the consolidation of manufacturing activities and processes at our site in Basel, Switzerland and closure of our production facilities in Basel, Switzerland.

During the three months ended March 31, 2012, our Pigments segment recorded charges of $1 million related to the closure of our Grimsby, U.K. plant.

DIRECT AND SUBSIDIARY DEBT

Huntsman Corporation's direct debt and guarantee obligations consist of a guarantee of certain indebtedness incurred from time to time to finance certain insurance premiums. Substantially all of our other debt, including the facilities described below, has been incurred by our subsidiaries (primarily Huntsman International). Huntsman Corporation is not a guarantor of such subsidiary debt.

Certain of our subsidiaries are designated as nonguarantor subsidiaries and have third-party debt agreements. These debt agreements contain certain restrictions with regard to dividends, distributions, loans or advances. In certain circumstances, the consent of a third party would be required prior to the transfer of any cash or assets from these subsidiaries to us.

Amendment to Credit Agreement

On March 11, 2013, Huntsman International entered into an eighth amendment to its Senior Credit Facilities. The amendment provided for an additional term loan of $225 million, the net proceeds of which were used to repay in full the remaining $193 million principal amount outstanding under our Term Loan B and for general corporate purposes. The additional term loan was recorded at its carrying value of $224 million as of March 31, 2013. The additional term loan has identical terms to our Extended Term Loan B.

In connection with this debt repayment, we recognized a loss on early extinguishment of debt of approximately $1 million.

Senior Credit Facilities

As of March 31, 2013, our Senior Credit Facilities consisted of our revolving credit facility ("Revolving Facility"), Extended Term Loan B, our extended term loan B facility—series 2 ("Extended Term Loan B—Series 2") and our term loan C facility ("Term Loan C") as follows (dollars in millions):

Facility	Committed Amount	Principal Outstanding			Carrying Value			Interest Rate(2)

Revolving Facility	$400	$	—	(1)	$	—	(1)	USD LIBOR plus 2.50%	2017	(3)

Term Loan C	NA		419			395		USD LIBOR plus 2.25%	2016

(1): We had no borrowings outstanding under our Revolving Facility; we had approximately $18 million (U.S. dollar equivalents) of letters of credit and bank guarantees issued and outstanding under our Revolving Facility.
(2): The applicable interest rate of the Senior Credit Facilities is subject to certain secured leverage ratio thresholds. As of March 31, 2013, the weighted average interest rate on our outstanding balances under the Senior Credit Facilities was approximately 3%.
(3): The maturity of the Revolving Facility commitments will accelerate if we do not repay, refinance or have a minimum level of liquidity available to enable us to repay our Term Loan C due June 30, 2016.

Our obligations under the Senior Credit Facilities are guaranteed by substantially all of our domestic subsidiaries and certain of our foreign subsidiaries (collectively, the "Guarantors"), and are secured by a first priority lien on substantially all of our domestic property, plant and equipment, the stock of all of our material domestic subsidiaries and certain foreign subsidiaries, and pledges of intercompany notes between certain of our subsidiaries.

Amendments to A/R Programs

On April 29, 2013, Huntsman International entered into an amendment to the EU A/R Program. This amendment, among other things, extends the scheduled commitment termination date of the EU A/R Program by two years to April 2016 and reduces the applicable margin on borrowings to 1.35%.

On April 29, 2013, Huntsman International entered into an amendment to the U.S. A/R Program. This amendment, among other things, extends the scheduled commitment termination date of the U.S. A/R Program by two years to April 2016, provides for additional availability under the U.S. A/R program and reduces the applicable margin on borrowings to 1.10%.

Notes

On March 4, 2013, pursuant to an indenture entered into on November 19, 2012, Huntsman International issued $250 million aggregate principal amount of additional 2020 Senior Notes. The notes are recorded at carrying value of $246 million as of March 31, 2013. Huntsman International applied the net proceeds to redeem the remaining $200 million in aggregate principal amount of its 2016 Senior Notes, to pay associated accrued interest and for general corporate purposes.

The 2020 Senior Notes bear interest at the rate of 4.875% per year payable semi-annually on May 15 and November 15 of each year, beginning on May 15, 2013 and are due on November 15, 2020. Huntsman International may redeem the 2020 Senior Notes in whole or in part at any time prior to August 17, 2020 at a price equal to 100% of the principal amount thereof plus a "make-whole" premium and accrued and unpaid interest.

The 2020 Senior Notes are general unsecured senior obligations of Huntsman International and are guaranteed on a general unsecured senior basis by the Guarantors. The indenture with respect to the 2020 Senior Notes imposes certain limitations on the ability of Huntsman International and its subsidiaries to, among other things, incur additional indebtedness secured by any principal properties, incur indebtedness of nonguarantor subsidiaries, enter into sale and leaseback transactions with respect to any principal properties and consolidate or merge with or into any other person or lease, sell or transfer all or substantially all of its properties and assets. Upon the occurrence of certain change of control events, holders of the 2020 Senior Notes will have the right to require that Huntsman International purchase all or a portion of such holder's 2020 Senior Notes in cash at a purchase price equal to 101% of the principal amount thereof plus accrued and unpaid interest to the date of repurchase.

As of March 31, 2013, we had outstanding the following notes (monetary amounts in millions):

Notes	Maturity			Amount Outstanding

2020 Senior Notes	November 2020	4.875	%	$650 ($646 carrying value)

Variable Interest Entity Debt

As of March 31, 2013, Arabian Amines Company had $179 million outstanding under its loan commitments and debt financing arrangements. Arabian Amines Company, our consolidated 50%-owned joint venture, is currently not in compliance with payment and other obligations under these loan commitments. We do not guarantee these loan commitments and Arabian Amines Company is not a guarantor of any of our other debt obligations, and the non-compliance with these financial covenants does not affect any of our other debt obligations. We are currently in discussions with the lenders under these loan commitments and expect to resolve the noncompliance. As of March 31, 2013, the amounts outstanding under these loan commitments were classified as current on our condensed consolidated balance sheets (unaudited).

Note Payable from Huntsman International to Huntsman Corporation

As of March 31, 2013, we have a loan of $840 million to our subsidiary, Huntsman International (the "Intercompany Note"). The Intercompany Note is unsecured and $100 million of the outstanding amount is classified as current as of March 31, 2013 on our condensed consolidated balance sheets (unaudited). As of March 31, 2013, under the terms of the Intercompany Note, Huntsman International promises to pay us interest on the unpaid principal amount at a rate per annum based on the previous monthly average borrowing rate obtained under our U.S. A/R Program, less 10 basis points (provided that the rate shall not exceed an amount that is 25 basis points less than the monthly average borrowing rate obtained for the U.S. LIBOR-based borrowings under our Revolving Facility).

COMPLIANCE WITH COVENANTS

We believe that we are in compliance with the covenants contained in the agreements governing our material debt instruments, including our Senior Credit Facilities, our A/R Programs and our notes. However, Arabian Amines Company, our consolidated 50%-owned joint venture, is currently not in compliance with payment and other obligations under its loan commitments. See "—Variable Interest Entity Debt" above.

Our material financing arrangements contain certain covenants with which we must comply. A failure to comply with a covenant could result in a default under a financing arrangement unless we obtained an appropriate waiver or forbearance (as to which we can provide no assurance). A default under these material financing arrangements generally allows debt holders the option to declare the underlying debt obligations immediately due and payable. Furthermore, certain of our material financing arrangements contain cross-default and cross-acceleration provisions under which a failure to comply with the covenants in one financing arrangement may result in an event of default under another financing arrangement.

Our Senior Credit Facilities are subject to a single financial covenant (the "Leverage Covenant") which applies only to the Revolving Facility and is tested at the Huntsman International level. The Leverage Covenant is applicable only if borrowings, letters of credit or guarantees are outstanding under the Revolving Facility (cash collateralized letters of credit or guarantees are not deemed outstanding). The Leverage Covenant is a net senior secured leverage ratio covenant which requires that Huntsman International's ratio of senior secured debt to EBITDA (as defined in the applicable agreement) is not more than 3.75 to 1.

If in the future Huntsman International fails to comply with the Leverage Covenant, then we may not have access to liquidity under our Revolving Facility. If Huntsman International failed to comply with the Leverage Covenant at a time when we had uncollateralized loans or letters of credit outstanding under the Revolving Facility, Huntsman International would be in default under the Senior Credit Facilities, and, unless Huntsman International obtained a waiver or forbearance with respect to such default (as to which we can provide no assurance), Huntsman International could be required to pay off the balance of the Senior Credit Facilities in full, and we may not have further access to such facilities.

The agreements governing our A/R Programs also contain certain receivable performance metrics. Any material failure to meet the applicable A/R Programs' metrics in the future could lead to an early termination event under the A/R Programs, which could require us to cease our use of such facilities, prohibiting us from additional borrowings against our receivables or, at the discretion of the lenders, requiring that we repay the A/R Programs in full. An early termination event under the A/R Programs would also constitute an event of default under our Senior Credit Facilities, which could require us to pay off the balance of the Senior Credit Facilities in full and could result in the loss of our Senior Credit Facilities.

8. DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

We are exposed to market risks, such as changes in interest rates, foreign exchange rates and commodity pricing risks. From time to time, we enter into transactions, including transactions involving derivative instruments, to manage certain of these exposures.

comprehensive loss, to the extent effective, and will be recognized in the income statement when the hedged item affects earnings. To the extent applicable, we perform effectiveness assessments in order to use hedge accounting at each reporting period. For a derivative that does not qualify as a hedge, changes in fair value are recognized in earnings.

We also hedge our net investment in certain European operations. Changes in the fair value of the hedge in the net investment of certain European operations are recorded in accumulated other comprehensive loss.

Our cash flows and earnings are subject to fluctuations due to exchange rate variation. Our revenues and expenses are denominated in various foreign currencies. From time to time, we may enter into foreign currency derivative instruments to minimize the short-term impact of movements in foreign currency rates. Where practicable, we generally net multicurrency cash balances among our subsidiaries to help reduce exposure to foreign currency exchange rates. Certain other exposures may be managed from time to time through financial market transactions, principally through the purchase of spot or forward foreign exchange contracts (generally with maturities of one year or less). We do not hedge our foreign currency exposures in a manner that would eliminate the effect of changes in exchange rates on our cash flows and earnings. As of March 31, 2013, we had approximately $229 million in notional amount (in U.S. dollar equivalents) outstanding in forward foreign currency contracts.

On December 9, 2009, we entered into a five-year interest rate contract to hedge the variability caused by monthly changes in cash flow due to associated changes in LIBOR under our Senior Credit Facilities. The notional value of the contract is $50 million, and it has been designated as a cash flow hedge. The effective portion of the changes in the fair value of the swap was recorded in other comprehensive loss. We will pay a fixed 2.6% on the hedge and receive the one-month LIBOR rate. As of March 31, 2013, the fair value of the hedge was $2 million and was recorded in other noncurrent liabilities on our condensed consolidated balance sheets (unaudited).

On January 19, 2010, we entered into an additional five-year interest rate contract to hedge the variability caused by monthly changes in cash flow due to associated changes in LIBOR under our Senior Credit Facilities. The notional value of the contract is $50 million, and it has been designated as a cash flow hedge. The effective portion of the changes in the fair value of the swap was recorded as other comprehensive loss. We will pay a fixed 2.8% on the hedge and receive the one-month LIBOR rate. As of March 31, 2013, the fair value of the hedge was $2 million and was recorded in other noncurrent liabilities on our condensed consolidated balance sheets (unaudited).

On September 1, 2011, we entered into a $50 million forward interest rate contract that will begin in December 2014 with maturity in April 2017 and a $50 million forward interest rate contract that will begin in January 2015 with maturity in April 2017. These two forward contracts are to hedge the variability caused by monthly changes in cash flow due to associated changes in LIBOR under our Senior Credit Facilities once our existing interest rate hedges mature. These swaps are designated as cash flow hedges and the effective portion of the changes in the fair value of the swaps were recorded in other comprehensive income. Both interest rate contracts will pay a fixed 2.5% on the hedge and receive the one-month LIBOR rate once the contracts begin in 2014 and 2015, respectively. As of

March 31, 2013, the combined fair value of these two hedges was $4 million and was recorded in other noncurrent liabilities on our condensed consolidated balance sheets (unaudited).

In 2009, Sasol-Huntsman entered into derivative transactions to hedge the variable interest rate associated with its local credit facility. These derivative rate hedges include a floating to fixed interest rate contract providing Sasol-Huntsman with EURIBOR interest payments for a fixed payment of 3.62% and a cap for future periods with a strike price of 3.62%. In connection with the consolidation of Sasol-Huntsman as of April 1, 2011, the interest rate contract is now included in our consolidated results. See "Note 5. Variable Interest Entities." The notional amount of the hedge as of March 31, 2013 was €42 million (approximately $54 million) and the derivative transactions do not qualify for hedge accounting. As of March 31, 2013, the fair value of this hedge was €2 million (approximately $3 million) and was recorded in other noncurrent liabilities on our condensed consolidated balance sheets (unaudited). For the three months ended March 31, 2013, we recorded additional interest expense of nil due to changes in the fair value of the swap.

Beginning in 2009, Arabian Amines Company entered into a 12-year floating to fixed interest rate contract providing for a receipt of LIBOR interest payments for a fixed payment of 5.02%. In connection with the consolidation of Arabian Amines Company as of July 1, 2010, the interest rate contract is now included in our consolidated results. See "Note 5. Variable Interest Entities." The notional amount of the swap as of March 31, 2013 was $34 million, and the interest rate contract is not designated as a cash flow hedge. As of March 31, 2013, the fair value of the swap was $5 million and was recorded as other noncurrent liabilities on our condensed consolidated balance sheets (unaudited). For the three months ended March 31, 2013, we recorded additional interest expense of $1 million due to changes in fair value of the swap. As of March 31, 2013, Arabian Amines Company was not in compliance with payment and other obligations contained in its loan commitments. For more information, see "Note 7. Debt—Direct and Subsidiary Debt—Variable Interest Entity Debt."

In conjunction with the issuance of our 8.625% senior subordinated notes due 2020, we entered into cross-currency interest rate contracts with three counterparties. On March 17, 2010, we made payments of $350 million to these counterparties and received €255 million from these counterparties, and on maturity (March 15, 2015) we are required to pay €255 million to these counterparties and will receive $350 million from these counterparties. On March 15 and September 15 of each year, we will receive U.S. dollar interest payments of approximately $15 million (equivalent to an annual rate of 8.625%) and make interest payments of approximately €11 million (equivalent to an annual rate of approximately 8.41%). This swap is designated as a hedge of net investment for financial reporting purposes. As of March 31, 2013, the fair value of this swap was $29 million and was recorded in other noncurrent assets on our condensed consolidated balance sheets (unaudited).

We finance certain of our non-U.S. subsidiaries with intercompany loans that are, in many cases, denominated in currencies other than the entities' functional currency. We manage the net foreign currency exposure created by this debt through various means, including cross-currency swaps, the designation of certain intercompany loans as permanent loans because they are not expected to be repaid in the foreseeable future and the designation of certain debt and swaps as net investment hedges.

Foreign currency transaction gains and losses on intercompany loans that are not designated as permanent loans are recorded in earnings. Foreign currency transaction gains and losses on intercompany loans that are designated as permanent loans are recorded in other comprehensive income. From time to time, we review such designation of intercompany loans.

We review our non-U.S. dollar denominated debt and derivative instruments to determine the appropriate amounts designated as hedges. As of March 31, 2013, we have designated approximately €255 million (approximately $325 million) of euro-denominated debt and cross-currency interest rate contracts as a hedge of our net investment. For the three months ended March 31, 2013, the amount of gain recognized on the hedge of our net investment was $10 and was recorded in other comprehensive (loss) income on our condensed consolidated statements of comprehensive (loss) income (unaudited). As of March 31, 2013, we had approximately €999 million (approximately $1,276 million) in net euro assets.

The fair values of financial instruments were as follows (dollars in millions):

	Carrying Value			Estimated Fair Value			Carrying Value			Estimated Fair Value
Non-qualified employee benefit plan investments	$	17		$	17		$	14		$	14

Long-term debt (including current portion)		(3,787	)		(3,928	)		(3,702	)		(3,869	)

The carrying amounts reported in our condensed consolidated balance sheets (unaudited) of cash and cash equivalents, accounts receivable and accounts payable approximate fair value because of the immediate or short-term maturity of these financial instruments. The fair value of non-qualified employee benefit plan investments is obtained through market observable pricing using prevailing market prices. The estimated fair values of our long-term debt are based on quoted market prices for the identical liability when traded as an asset in an active market (Level 1).

The fair value estimates presented herein are based on pertinent information available to management as of March 31, 2013 and December 31, 2012. Although management is not aware of any factors that would significantly affect the estimated fair value amounts, such amounts have not been comprehensively revalued for purposes of these financial statements since March 31, 2013 and current estimates of fair value may differ significantly from the amounts presented herein.

(1): We are party to cross-currency interest rate contracts that are measured at fair value in the financial statements. These instruments have historically been categorized by us as Level 3 within the fair value hierarchy due to an unobservable input associated with the credit valuation adjustment, which we deemed to be a significant input to the overall measurement of fair value at inception. During the three months ended March 31, 2012, this credit valuation adjustment had ceased to be a significant input to the entire fair value measurement of these instruments. The remaining inputs which are significant to the fair value measurement of these instruments represent observable market inputs that are inputs other than quoted prices (Level 2 inputs).

Our policy is to recognize transfers between levels within the fair value hierarchy as of the beginning of the reporting period. Due to the change in significance of the credit valuation adjustment to the entire fair value measurement of these instruments, effective January 1, 2012, we have categorized our cross-currency interest rate contracts as Level 2 within the fair value hierarchy.

We also have assets that under certain conditions are subject to measurement at fair value on a non-recurring basis. These assets include property, plant and equipment and those associated with acquired businesses, including goodwill and intangible assets. For these assets, measurement at fair

13. COMMITMENTS AND CONTINGENCIES

LEGAL MATTERS

Asbestos Litigation

We have been named as a "premises defendant" in a number of asbestos exposure cases, typically claims by nonemployees of exposure to asbestos while at a facility. These complaints generally do not provide the necessary information about the time period in which the alleged injuries occurred or the alleged exposures giving rise to the asserted liability. This information, which would be central to any estimate of probable loss, generally must be obtained through legal discovery.

Where a claimant's alleged exposure occurred prior to our ownership of the relevant "premises," the prior owners generally have contractually agreed to retain liability for, and to indemnify us against, asbestos exposure claims. This indemnification is not subject to any time or dollar amount limitations. Upon service of a complaint in one of these cases, we tender it to the prior owner. Rarely do the complaints in these cases state the amount of damages being sought. The prior owner accepts

responsibility for the conduct of the defense of the cases and payment of any amounts due to the claimants. In our nineteen-year experience with tendering these cases, we have not made any payment with respect to any tendered asbestos cases. We believe that the prior owners have the intention and ability to continue to honor their indemnity obligations, although we cannot assure you that they will continue to do so or that we will not be liable for these cases if they do not.

The following table presents for the periods indicated certain information about cases for which service has been received that we have tendered to the prior owner, all of which have been accepted.

(1): Although the indemnifying party informs us when tendered cases have been resolved, it generally does not inform us of the settlement amounts relating to such cases, if any. The indemnifying party has informed us that it typically manages our defense together with the defense of other entities in such cases and resolves claims involving multiple defendants simultaneously, and that it considers the allocation of settlement amounts, if any, among defendants to be confidential and proprietary. Consequently, we are not able to provide the number of cases resolved with payment by the indemnifying party or the amount of such payments.

We have never made any payments with respect to these cases. As of March 31, 2013, we had an accrued liability of approximately $10 million relating to these cases and a corresponding receivable of approximately $10 million relating to our indemnity protection with respect to these cases. We cannot assure you that our liability will not exceed our accruals or that our liability associated with these cases would not be material to our financial condition, results of operations or liquidity; accordingly, we are not able to estimate the amount or range of loss in excess of our accruals. Additional asbestos exposure claims may be made against us in the future, and such claims could be material. However, because we are not able to estimate the amount or range of losses associated with such claims, we have made no accruals with respect to unasserted asbestos exposure claims as of March 31, 2013.

Certain cases in which we are a premises defendant are not subject to indemnification by prior owners or operators. However, we may be entitled to insurance or other recoveries in some of these cases. The following table presents for the periods indicated certain information about these cases.

We paid gross settlement costs for asbestos exposure cases that are not subject to indemnification of nil and $82,000 during the three months ended March 31, 2013 and 2012, respectively. As of March 31, 2013, we had no accrual relating to these cases. We cannot assure you that our liability will not exceed our accruals or that our liability associated with these cases would not be material to our financial condition, results of operations or liquidity; accordingly, we are not able to estimate the amount or range of loss in excess of our accruals. Additional asbestos exposure claims may be made against us in the future, and such claims could be material. However, because we are not able to estimate the amount or range of losses associated with such claims, we have made no accruals with respect to unasserted asbestos exposure claims as of March 31, 2013.

Antitrust Matters

We have been named as a defendant in two class action civil antitrust suits filed on February 9 and 12, 2010 in the U.S. District Court for the District of Maryland alleging that we and our co-defendants and other asserted co-conspirators conspired to fix prices of titanium dioxide sold in the U.S. between at least March 1, 2002 and the present. The suits were subsequently consolidated. The other defendants named in this matter are DuPont, Kronos and Millennium. On August 28, 2012, the court certified a class consisting of all U.S. customers who purchased titanium dioxide directly from defendants (the "Direct Purchasers") since February 1, 2003. A hearing to consider our motion for summary judgment is scheduled for June 25, 2013 and trial is set to begin September 9, 2013.

We have also been named as a defendant in a class action civil antitrust suit filed on March 15, 2013 in the U.S. District Court for the Northern District of California by purchasers of products made from titanium dioxide (the "Indirect Purchasers") making essentially the same allegations as the Direct Purchasers.

The plaintiffs in both the Direct Purchasers and Indirect Purchasers' actions seek to recover on behalf of their respective classes injunctive relief, treble damages or the maximum damages allowed by state law, costs of suit and attorneys fees. We are not aware of any illegal conduct by us or any of our employees. Nevertheless, we have incurred costs relating to these claims and could incur additional costs in amounts material to us. Because of the overall complexity of these cases, we are unable to reasonably estimate any possible loss or range of loss associated with these claims and we have made no accruals with respect to these claims.

Product Delivery Claim

We have been notified by a customer of potential claims related to our allegedly delivering a different product than it had ordered. Our customer claims that it was unaware that the different product had been delivered until after it had been used to manufacture materials which were subsequently sold. Originally, the customer stated that it had been notified of claims of up to an aggregate of €153 million (approximately $202 million) relating to this matter and believed that we may be responsible for all or a portion of these potential claims. Our customer has since resolved some of these claims and the aggregate amount of the current claims is now approximately €113 million (approximately $144 million). Based on the facts currently available to us, we believe that we are insured for any liability we may ultimately have in excess of $10 million. However, no assurance can be given regarding our ultimate liability or costs. We believe the range of possible loss to our Company in this matter to be between €0 and €113 million and have made no accrual with respect to this matter.

Indemnification Matter

On July 3, 2012, Deutsche Bank Securities Inc. and Credit Suisse Securities (USA) LLC, or the banks, demanded that we indemnify them for claims brought by certain MatlinPatterson entities that were formerly our shareholders, the plaintiffs, in litigation filed June 19, 2012 in the 9th District Court in Montgomery County, Texas. The banks assert that they are entitled to indemnification pursuant to the Agreement of Compromise and Settlement between the banks and our Company, dated June 22, 2009, wherein the banks and our Company settled claims that we brought relating to the failed merger with Hexion. The plaintiffs claim that the banks knowingly made materially false representations about the nature of the financing for the acquisition of our Company by Hexion and that they suffered substantial losses to their 19 million shares of our common stock as a result of the banks' misrepresentations. The plaintiffs are asserting statutory fraud, common law fraud and aiding and abetting statutory fraud and are seeking actual damages, exemplary damages, costs and attorney's fees, pre-judgment and post-judgment interest. We denied the banks' indemnification demand. On December 21, 2012, the court dismissed the plaintiffs' claims. The plaintiffs filed a motion for reconsideration before the trial court on January 18, 2013 and a Notice of Appeal to the Ninth Court of Appeals at Beaumont, Texas.

Other Proceedings

We are a party to various other proceedings instituted by private plaintiffs, governmental authorities and others arising under provisions of applicable laws, including various environmental, products liability and other laws. Except as otherwise disclosed in this report, we do not believe that the outcome of any of these matters will have a material effect on our financial condition, results of operations or liquidity.

14. ENVIRONMENTAL, HEALTH AND SAFETY MATTERS

ENVIRONMENTAL, HEALTH AND SAFETY MATTERS

General

We are subject to extensive federal, state, local and international laws, regulations, rules and ordinances relating to safety, pollution, protection of the environment, product management and distribution, and the generation, storage, handling, transportation, treatment, disposal and remediation of hazardous substances and waste materials. In the ordinary course of business, we are subject to frequent environmental inspections and monitoring and occasional investigations by governmental enforcement authorities. In addition, our production facilities require operating permits that are subject to renewal, modification and, in certain circumstances, revocation. Actual or alleged violations of safety laws, environmental laws or permit requirements could result in restrictions or prohibitions on plant operations or product distribution, substantial civil or criminal sanctions, as well as, under some environmental laws, the assessment of strict liability and/or joint and several liability. Moreover, changes in environmental regulations could inhibit or interrupt our operations, or require us to modify our facilities or operations. Accordingly, environmental or regulatory matters may cause us to incur significant unanticipated losses, costs or liabilities.

Environmental, Health and Safety Systems

We are committed to achieving and maintaining compliance with all applicable environmental, health and safety ("EHS") legal requirements, and we have developed policies and management systems that are intended to identify the multitude of EHS legal requirements applicable to our operations, enhance compliance with applicable legal requirements, improve the safety of our employees, contractors, community neighbors and customers and minimize the production and emission of wastes and other pollutants. Although EHS legal requirements are constantly changing and are frequently difficult to comply with, these EHS management systems are designed to assist us in our compliance goals while also fostering efficiency and improvement and reducing overall risk to us.

EHS Capital Expenditures

We may incur future costs for capital improvements and general compliance under EHS laws, including costs to acquire, maintain and repair pollution control equipment. For the three months ended March 31, 2013 and 2012, our capital expenditures for EHS matters totaled $16 million and $19 million, respectively. Because capital expenditures for these matters are subject to evolving regulatory requirements and depend, in part, on the timing, promulgation and enforcement of specific requirements, our capital expenditures for EHS matters have varied significantly from year to year and we cannot provide assurance that our recent expenditures are indicative of future amounts we may spend related to EHS and other applicable laws.

Remediation Liabilities

We have incurred, and we may in the future incur, liability to investigate and clean up waste or contamination at our current or former facilities or facilities operated by third parties at which we may have disposed of waste or other materials. Similarly, we may incur costs for the cleanup of waste that

Table of Contents

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) (Continued)

was disposed of prior to the purchase of our businesses. Under some circumstances, the scope of our liability may extend to damages to natural resources.

Under the Comprehensive Environmental Response, Compensation, and Liability Act ("CERCLA") and similar state laws, a current or former owner or operator of real property may be liable for remediation costs regardless of whether the release or disposal of hazardous substances was in compliance with law at the time it occurred, and a current owner or operator may be liable regardless of whether it owned or operated the facility at the time of the release. Outside the U.S., analogous contaminated property laws, such as those in effect in France and Australia, can hold past owners and/or operators liable for remediation at former facilities. Currently, there are approximately 10 former facilities or third-party sites in the U.S. for which we have been notified of potential claims against us for cleanup liabilities, including, but not limited to, sites listed under CERCLA. Based on current information and past experiences at other CERCLA sites, we do not expect these third-party claims to have a material impact on our financial statements.

One of these sites, the North Maybe Canyon Mine site, involves a former phosphorous mine near Soda Springs, Idaho, which is believed to have been operated by a predecessor company to us. In 2004, the U.S. Forest Service notified us that we are a CERCLA potentially responsible party ("PRP") for contamination originating from the site. In February 2010, we and Wells Cargo (another PRP) agreed to conduct a Remedial Investigation/Feasibility Study of a portion of the site and are currently engaged in that process. At this time, we are unable to reasonably estimate our potential liabilities at this site.

In addition, under the Resource Conservation and Recovery Act ("RCRA") and similar state laws, we may be required to remediate contamination originating from our properties as a condition to our hazardous waste permit. Some of our manufacturing sites have an extended history of industrial chemical manufacturing and use, including on-site waste disposal. We are aware of soil, groundwater or surface contamination from past operations at some of our sites, and we may find contamination at other sites in the future. For example, our Port Neches, Texas, and Geismar, Louisiana, facilities are the subject of ongoing remediation requirements imposed under RCRA. Similar laws exist in a number of locations in which we currently operate, or previously operated, manufacturing facilities, such as Australia, India, France, Hungary and Italy.

By letter dated March 7, 2006, our former Base Chemicals and Polymers facility in West Footscray, Australia, was issued a clean-up notice by the Environmental Protection Authority Victoria ("EPA Victoria") due to concerns about soil and groundwater contamination emanating from the site. On August 23, 2010, EPA Victoria revoked the second clean-up notice and issued a revised notice that included a requirement for financial assurance for the remediation. We have reached agreement with the agency that a mortgage on the land will be held by the agency as financial surety during the period covered by the current clean-up notice, which ends on July 30, 2014. As of March 31, 2013, we had an accrued liability of approximately $29 million related to estimated environmental remediation costs at this site. We can provide no assurance that the agency will not seek to institute additional requirements for the site or that additional costs will not be associated with the clean up.

In many cases, our potential liability arising from historical contamination is based on operations and other events occurring prior to our ownership of a business or specific facility. In these situations,

HUNTSMAN INTERNATIONAL LLC AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) (Continued)

14. ENVIRONMENTAL, HEALTH AND SAFETY MATTERS (Continued)

we frequently obtained an indemnity agreement from the prior owner addressing remediation liabilities arising from pre-closing conditions. We have successfully exercised our rights under these contractual covenants for a number of sites and, where applicable, mitigated our ultimate remediation liability. We cannot assure you, however, that the liabilities for all such matters subject to indemnity, will be honored by the prior owner or that our existing indemnities will be sufficient to cover our liabilities for such matters.

Based on available information and the indemnification rights we believe are likely to be available, we believe that the costs to investigate and remediate known contamination will not have a material effect on our financial statements. However, if such indemnities are not honored or do not fully cover the costs of investigation and remediation or we are required to contribute to such costs, then such expenditures may have a material effect on our financial statements. At the current time, we are unable to estimate the total cost, exclusive of indemnification benefits, to remediate any of the known contamination sites.

Environmental Reserves

We have accrued liabilities relating to anticipated environmental cleanup obligations, site reclamation and closure costs and known penalties. Liabilities are recorded when potential liabilities are either known or considered probable and can be reasonably estimated. Our liability estimates are calculated using present value techniques as appropriate and are based upon requirements placed upon us by regulators, available facts, existing technology and past experience. The environmental liabilities do not include amounts recorded as asset retirement obligations. We had accrued $34 million for environmental liabilities as of both March 31, 2013 and December 31, 2012. Of these amounts, $5 million and $10 million were classified as accrued liabilities in our consolidated balance sheets as of March 31, 2013 and December 31, 2012, respectively, and $29 million and $24 million were classified as other noncurrent liabilities in our consolidated balance sheets as of March 31, 2013 and December 31, 2012, respectively. In certain cases, our remediation liabilities may be payable over periods of up to 30 years. We may incur losses for environmental remediation in excess of the amounts accrued; however, we are not able to estimate the amount or range of such potential excess.

REGULATORY DEVELOPMENTS

The EU regulatory framework for chemicals, called "REACH", became effective in 2007 and is designed to be phased in gradually over 11 years. As a REACH-regulated company that manufactures in or imports more than one metric ton per year of a chemical substance into the European Economic Area, we were required to pre-register with the European Chemicals Agency ("ECHA"), such chemical substances and isolated intermediates to take advantage of the 11 year phase-in period. To meet our compliance obligations, a cross-business REACH team was established, through which we were able to fulfill all required pre-registrations and our first phase registrations by the November 30, 2010 deadline. While we continue our registration efforts to meet the next registration deadline of May 31, 2013, our REACH implementation team is now strategically focused on the authorization phase of the REACH process, directing its efforts to address "Substances of Very High Concern" and evaluating potential business implications. Where warranted, evaluation of substitute chemicals will be an important element

of our ongoing manufacturing sustainability efforts. As a chemical manufacturer with global operations, we are also actively monitoring and addressing analogous regulatory regimes being considered or implemented outside of the EU, such as in Korea and Taiwan.

Although the total long-term cost for REACH compliance is unknown at this time, we spent approximately $8 million, $5 million and $9 million in 2012, 2011 and 2010, respectively, to meet the initial REACH requirements. We cannot provide assurance that these recent expenditures are indicative of future amounts that we may be required to spend for REACH compliance.

GREENHOUSE GAS REGULATION

Globally, our operations are increasingly subject to regulations that seek to reduce emissions of "greenhouse gases" ("GHGs"), such as carbon dioxide and methane, which may be contributing to changes in the Earth's climate. At the most recent negotiations of the Conference of the Parties to the Kyoto Protocol, a limited group of nations, including the European Union ("EU"), agreed to a second commitment period for the Kyoto Protocol, an international treaty that provides for reductions in GHG emissions. More significantly, the European Union GHG Emissions Trading System, established pursuant to the Kyoto Protocol to reduce GHG emissions in the EU, has just entered its third phase and ongoing reforms at the EU level—including measures to prop up carbon credit prices and ban the use of certain types of certified emission reductions—may increase our operating costs. Australia has also adopted a carbon trading system that has been recognized for formal linkage with the EU trading system by 2018. Australia's GHG cap-and-trade program may impose compliance obligations upon our operations that may increase our operating costs. In the U.S., California has commenced the first compliance period of its cap-and-trade program.

Federal climate change legislation in the U.S. appears unlikely in the near-term. As a result, domestic efforts to curb GHG emissions will be led by the U.S. Environmental Protection Agency's (the "EPA") GHG regulations and the efforts of states. To the extent that our domestic operations are subject to the EPA's GHG regulations, we may face increased capital and operating costs associated with new or expanded facilities. Expansions of our existing facilities or construction of new facilities may be subject to the Clean Air Act's Prevention of Significant Deterioration requirements under the EPA's GHG "Tailoring Rule." Our facilities are also subject to the EPA's Mandatory Reporting of Greenhouse Gases rule, and the collection and reporting of GHG data may increase our operational costs.

Under a consent decree with states and environmental groups, the EPA is due to propose new source performance standards for GHG emissions from refineries. These standards could significantly increase the costs of constructing or adding capacity to refineries and may ultimately increase the costs or decrease the supply of refined products. Either of these events could have an adverse effect on our business.

We are already managing and reporting GHG emissions, to varying degrees, as required by law for our sites in locations subject to Kyoto Protocol obligations and/or EU emissions trading scheme requirements. Although these sites are subject to existing GHG legislation, few have experienced or anticipate significant cost increases as a result of these programs, although it is possible that GHG

emission restrictions may increase over time. Potential consequences of such restrictions include capital requirements to modify assets to meet GHG emission restrictions and/or increases in energy costs above the level of general inflation, as well as direct compliance costs. Currently, however, it is not possible to estimate the likely financial impact of potential future regulation on any of our sites.

Finally, it should be noted that some scientists have concluded that increasing concentrations of GHG in the earth's atmosphere may produce climate changes that have significant physical effects, such as increased frequency and severity of storms, droughts, and floods and other climatic events. If any of those effects were to occur, they could have an adverse effect on our assets and operations.

PORT NECHES FLARING MATTER

As part of the EPA's national enforcement initiative on flaring operations and by letter dated October 12, 2012, the U.S. Department of Justice (the "DOJ") notified us that we were in violation of the Clean Air Act (the "CAA") based on our response to a 2010 CAA Section 114 Information Request. The EPA has used the enforcement initiative to bring similar actions against refiners and other chemical manufacturers. Specifically, the EPA alleged violations at our Port Neches, Texas facility from 2007-2012 for flare operations not consistent with good pollution control practice and not in compliance with certain flare-related regulations. As a result of these findings, the EPA referred this matter to the DOJ. We have been engaged in discussions with the DOJ and the EPA regarding these alleged violations and are in the process of reviewing and assessing the allegations and will formally respond to the DOJ by early May. We are currently unable to determine the likelihood or magnitude of potential penalty or injunctive relief that may be incurred in resolving this matter.

15. STOCK-BASED COMPENSATION PLANS

Under the Huntsman Corporation Stock Incentive Plan, as amended and restated (the "Stock Incentive Plan"), a plan approved by stockholders, we may grant nonqualified stock options, incentive stock options, stock appreciation rights, restricted stock, phantom stock, performance awards and other stock-based awards to our employees, directors and consultants and to employees and consultants of our subsidiaries, provided that incentive stock options may be granted solely to employees. The terms of the grants are fixed at the grant date. As of March 31, 2013, we were authorized to grant up to 32.6 million shares under the Stock Incentive Plan. As of March 31, 2013, we had 6 million shares remaining under the Stock Incentive Plan available for grant. Option awards have a maximum contractual term of 10 years and generally must have an exercise price at least equal to the market price of our common stock on the date the option award is granted. Stock-based awards generally vest over a three-year period.

15. STOCK-BASED COMPENSATION PLANS (Continued)

The compensation cost from continuing operations under the Stock Incentive Plan for our Company and Huntsman International were as follows (dollars in millions):

	Three months ended March 31,

	2013		2012
Huntsman Corporation compensation cost	$	8	$	10
Huntsman International compensation cost		7		9

The total income tax benefit recognized in the statements of operations for us and Huntsman International for stock-based compensation arrangements were $2 million and $3 million, respectively, for the three months ended March 31, 2013 and 2012.

STOCK OPTIONS

The fair value of each stock option award is estimated on the date of grant using the Black-Scholes valuation model that uses the assumptions noted in the following table. Expected volatilities are based on the historical volatility of our common stock through the grant date. The expected term of options granted was estimated based on the contractual term of the instruments and employees' expected exercise and post-vesting employment termination behavior. The risk-free rate for periods within the contractual life of the option was based on the U.S. Treasury yield curve in effect at the time of grant. The assumptions noted below represent the weighted average of the assumptions utilized for stock options granted during the periods.

	Three months ended March 31,

	2013			2012
Dividend yield		2.8	%		3.0	%
Expected volatility		62.6	%		65.3	%
Risk-free interest rate		1.0	%		1.3	%
Expected life of stock options granted during the period		5.6 years			6.6 years

The weighted-average grant-date fair value of stock options granted during the three months ended March 31, 2013 was $7.92 per option. As of March 31, 2013, there was $16 million of total unrecognized compensation cost related to nonvested stock option arrangements granted under the Stock Incentive Plan. That cost is expected to be recognized over a weighted-average period of approximately 1.9 years.

The total intrinsic value of stock options exercised during the three months ended March 31, 2013 and 2012 was $9 million and $5 million, respectively.

NONVESTED SHARES

Nonvested shares granted under the Stock Incentive Plan consist of restricted stock, which is accounted for as an equity award, and phantom stock, which is accounted for as a liability award

(1): As of March 31, 2013, a total of 569,279 restricted stock units were vested, of which 52,941 vested during the three months ended March 31, 2013. These shares have not been reflected as vested shares in this table because, in accordance with the restricted stock unit agreements, shares of common stock are not issued for vested restricted stock units until termination of employment.

As of March 31, 2013, there was $31 million of total unrecognized compensation cost related to nonvested share compensation arrangements granted under the Stock Incentive Plan. That cost is expected to be recognized over a weighted-average period of approximately 2.1 years. The value of share awards that vested during the three months ended March 31, 2013 and 2012 was $17 million and $21 million, respectively.

16. INCOME TAXES

We use the asset and liability method of accounting for income taxes. Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial and tax reporting purposes. We evaluate deferred tax assets to determine whether it is more likely than not that they will be realized. Valuation allowances are reviewed on a tax jurisdiction basis to analyze whether there is sufficient positive or negative evidence to support a change in judgment about the realizability of the related deferred tax assets for each jurisdiction. These conclusions require significant judgment. In evaluating the objective evidence that historical results provide, we consider the cyclicality of businesses and cumulative income or losses during the applicable period. Cumulative losses incurred over the applicable period limits our ability to consider other subjective evidence such as our projections for the future. Changes in expected future income in applicable jurisdictions could affect the realization of deferred tax assets in those jurisdictions. During the three months ended March 31, 2013, on a discrete basis, we released a valuation allowance of $1 million on certain net deferred tax assets in Luxembourg. During the three months ended March 31, 2012, we recorded a net $1 million expense for changes in valuation allowance related to certain net deferred assets in Guatemala, Indonesia and China, with no change greater than $2 million.

16. INCOME TAXES (Continued)

During the three months ended March 31, 2013 and 2012, we recorded a net increase in unrecognized tax benefits with a corresponding income tax expense of $1 million for each period, resulting from the settlement of tax audits, the effective settlement of certain tax positions and the expiration of statutes of limitations, net of additions.

During the three months ended March 31, 2012, we were granted a tax holiday for the period from January 1, 2012 through December 31, 2016 with respect to certain income from Pigments products manufactured in Malaysia. We are required to make certain investments in order to enjoy the benefits of the tax holiday and we intend to make these investments. During the three months ended March 31, 2012, we recorded a discrete benefit of $3 million from de-recognition of a net deferred tax liability that will reverse during the holiday period. The amount of tax benefit to be realized from the tax holiday is directly dependent on the amount of future pre-tax income generated. We expect that the effects of the tax holiday will not be material to our provision for income taxes.

Huntsman Corporation

We recorded income tax benefit of $20 million and income tax expense of $60 million for the three months ended March 31, 2013 and 2012, respectively. Our tax expense is affected by the mix of income and losses in the tax jurisdictions in which we operate, as impacted by the presence of valuation allowances in certain tax jurisdictions. Our 2013 effective tax rate is significantly impacted by anticipated losses in tax jurisdictions where we have a full valuation allowance.

Huntsman International

Huntsman International recorded income tax benefit of $18 million and income tax expense of $61 million for the three months ended March 31, 2013 and 2012, respectively. Our tax expense is affected by the mix of income and losses in the tax jurisdictions in which we operate, as impacted by the presence of valuation allowances in certain tax jurisdictions. Our 2013 effective tax rate is significantly impacted by anticipated losses in tax jurisdictions where we have a full valuation allowance.

17. NET (LOSS) INCOME PER SHARE

Basic (loss) income per share excludes dilution and is computed by dividing net (loss) income attributable to Huntsman Corporation common stockholders by the weighted average number of shares outstanding during the period. Diluted income per share reflects all potential dilutive common shares outstanding during the period and is computed by dividing net income available to Huntsman Corporation common stockholders by the weighted average number of shares outstanding during the period increased by the number of additional shares that would have been outstanding as dilutive securities.

Additional stock-based awards of 7.0 million and 8.0 million weighted average equivalent shares of stock were outstanding during the three months ended March 31, 2013 and 2012, respectively. However, these stock-based awards were not included in the computation of diluted earnings per share for the three months ended March 31, 2013 and 2012 because the effect would be anti-dilutive.

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

FORWARD-LOOKING STATEMENTS

With respect to Huntsman Corporation, certain information set forth in this report contains "forward-looking statements" within the meaning of the federal securities laws. Huntsman International is a limited liability company, and, pursuant to Section 21E(b)(2)(E) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), the safe harbor for certain forward-looking statements is inapplicable to it. Forward-looking statements include statements concerning our plans, objectives, goals, strategies, future events, future revenues or performance, capital expenditures, financing needs, plans or intentions relating to acquisitions and other information that is not historical information. In some cases, forward-looking statements can be identified by terminology such as "believes," "expects," "may," "should," "anticipates," or "intends" or the negative of such terms or other comparable terminology, or by discussions of strategy. We may also make additional forward-looking statements from time to time. All such subsequent forward-looking statements, whether written or oral, by us or on our behalf, are also expressly qualified by these cautionary statements.

All forward-looking statements, including without limitation management's examination of historical operating trends, are based upon our current expectations and various assumptions. Our expectations, beliefs and projections are expressed in good faith and we believe there is a reasonable basis for them, but there can be no assurance that management's expectations, beliefs and projections will result or be achieved. All forward-looking statements apply only as of the date made. We undertake no obligation to publicly update or revise forward-looking statements which may be made to reflect events or circumstances after the date made or to reflect the occurrence of unanticipated events.

There are a number of risks and uncertainties that could cause our actual results to differ materially from the forward-looking statements contained in or contemplated by this report. Any forward-looking statements should be considered in light of the risks referenced in "Part I. Item 1A. Risk Factors" in our Annual Report on Form 10-K for the year ended December 31, 2012.

OVERVIEW

Business

RECENT DEVELOPMENTS

On April 29, 2013, Huntsman International entered into amendments to its U.S. A/R Program and its EU A/R Program. These amendments, among other things, extend the scheduled commitment

Table of Contents

termination date of the loan facilities under our A/R Programs to April 2016. For more information, see "Note 7. Debt—Direct and Subsidiary Debt—Amendments to A/R Programs."

On March 11, 2013, Huntsman International entered into an eighth amendment to its Senior Credit Facilities. The amendment provided for an additional term loan of $225 million, the net proceeds of which were used to repay in full the remaining $193 million principal amount outstanding under our Term Loan B and for general corporate purposes. We recognized a loss on early extinguishment of debt of approximately $1 million on this redemption. The additional term loan has identical terms to our Extended Term Loan B. See "Note 7. Debt—Direct and Subsidiary Debt—Amendment to Credit Agreement."

On March 4, 2013, Huntsman International, pursuant to an indenture entered into on November 19, 2012, issued $250 million aggregate principal amount of additional 2020 Senior Notes. Huntsman International applied the net proceeds to redeem the remaining $200 million in aggregate principal amount of its 2016 Senior Notes, to pay associated accrued interest and for general corporate purposes. We recognized a loss on early extinguishment of debt of approximately $34 million on this redemption. For more information, see "Note 7. Debt—Direct and Subsidiary Debt—Notes."

During the first quarter of 2013, we successfully completed the scheduled maintenance of our olefins and ethylene oxide facilities in Port Neches, Texas. This significant maintenance occurs approximately every four years at this facility. The total estimated impact on first quarter 2013 EBITDA related to this scheduled maintenance was approximately $55 million.

OUTLOOK

During the first quarter of 2013, we saw a meaningful improvement in our MDI polyurethane margins. We expect this trend to continue as industry fundamentals improve. With the successful restart of our Port Neches, Texas facility and our ongoing restructuring and cost cutting efforts, we expect year-over-year improvement collectively across all segments other than Pigments.

The following summarizes trends and key considerations that could impact the future performance of our operating segments:

Polyurethanes:

•: Improving MDI demand
•: Restructuring benefit
•: Continued strong demand for MTBE
•: Force majeure at our MDI facility in Rotterdam, The Netherlands in the second quarter of 2013
•: 2013 Adjusted EBITDA similar to 2012

Performance Products:

•: U.S. Gulf Coast raw material cost advantage
•: Further recovery in amines margins
•: 2013 Adjusted EBITDA similar to 2012

Advanced Materials:

•: Restructuring benefit
•: 2013 Adjusted EBITDA better than 2012

Table of Contents

Textile Effects:

•: Reorganization and restructuring benefit
•: 2013 Adjusted EBITDA positive

Pigments:

•: Favorable ilmenite raw material advantage versus traditional chloride ores
•: Near term contribution margin pressure
•: Improving contribution margins in the second half of 2013
•: 2013 Adjusted EBITDA less than 2012

We expect to spend approximately $450 million in 2013 on capital expenditures, net of reimbursements, for growth initiatives and maintenance.

We expect our full year 2013 adjusted effective tax rate to be approximately 35% and we expect our full year unadjusted effective tax rate to be approximately 45% primarily due to the effect of the tax valuation allowances and expected regional mix of income. We believe our long-term effective income tax rate will be approximately 30% to 35%.

NM—Not Meaningful

(1): Our management uses EBITDA and Adjusted EBITDA to assess financial performance. EBITDA is defined as net income attributable to Huntsman Corporation or Huntsman International, as appropriate, before interest, income taxes, depreciation and amortization. Adjusted EBITDA is computed by eliminating the following from EBITDA: (a) acquisition expenses; (b) EBITDA from discontinued operations; (c) loss on early extinguishment of debt; (d) certain legal settlements and related expenses; (e) amortization of pension and postretirement actuarial losses; and (f) restructuring, impairment, plant closing and transition costs (credits).

Beginning in 2013, we began to exclude the amortization of actuarial gains and losses associated with pension and postretirement benefits from adjusted EBITDA, adjusted net income (loss), adjusted net income (loss) attributable to Huntsman Corporation and adjusted diluted income (loss) per share. The amortization of actuarial gains and losses associated with pension and postretirement benefits arises from changes in actuarial assumptions and the difference between

Table of Contents

actual and expected returns on plan assets, and not from our normal, or "core," operations. There is diversity in accounting for these actuarial gains and losses within our industry, and we believe that removing these gains and losses provides management and investors greater transparency into the operational results of our businesses and enhances period-over-period comparability. The service cost, amortization of prior service cost (benefit), interest cost and expected return on plan assets components of our periodic pension and postretirement benefit costs (income) will continue to be included in adjusted EBITDA, adjusted net income (loss), adjusted net income (loss) attributable to Huntsman Corporation and adjusted diluted income (loss) per share. The amounts for prior periods have been recast to conform to the current presentation.

EBITDA and Adjusted EBITDA may not necessarily be comparable to other similarly titled measures used by other companies. There are material limitations associated with our use of these measures because they do not reflect overall financial performance, including the effects of interest, income taxes, depreciation and amortization. Our management compensates for the limitations of these measures by using them as a supplement to GAAP results.

For a reconciliation of EBITDA and Adjusted EBITDA to net income attributable to Huntsman Corporation or Huntsman International, as appropriate, see the tables below (dollars in millions):

(2): Adjusted net income is computed by eliminating the after-tax amounts related to the following from net (loss) income applicable to Huntsman Corporation or Huntsman International, as appropriate: (a) acquisition expenses; (b) loss from discontinued operations; (c) discount amortization on settlement financing; (d) loss on early extinguishment of debt; (e) certain legal settlements and related expenses; (f) amortization of pension and postretirement actuarial losses; and (g) restructuring, impairment and plant closing and transition costs. The income tax impacts, if any, of each adjusting item represent a ratable allocation of the total difference between the unadjusted tax expense and the total adjusted tax expense, computed without consideration of any adjusting items using a with and without approach. We do not adjust for changes in tax valuation allowances because we do not believe it provides more meaningful information than is provided under GAAP. Basic adjusted income per share excludes dilution and is computed by dividing adjusted net income by the weighted average number of shares outstanding during the period. Diluted net income per share reflects all potential dilutive common shares outstanding during the period and is computed by dividing adjusted net income by the weighted average number of shares outstanding during the period increased by the number of additional shares that would have been outstanding as dilutive securities.

Beginning in 2013, we began to exclude the amortization of actuarial gains and losses associated with pension and postretirement benefits from adjusted EBITDA, adjusted net income (loss),

Table of Contents

adjusted net income (loss) attributable to Huntsman Corporation and adjusted diluted income (loss) per share. The amortization of actuarial gains and losses associated with pension and postretirement benefits arises from changes in actuarial assumptions and the difference between actual and expected returns on plan assets, and not from our normal, or "core," operations. There is diversity in accounting for these actuarial gains and losses within our industry, and we believe that removing these gains and losses provides management and investors greater transparency into the operational results of our businesses and enhances period-over-period comparability. The service cost, amortization of prior service cost (benefit), interest cost and expected return on plan assets components of our periodic pension and postretirement benefit costs (income) will continue to be included in adjusted EBITDA, adjusted net income (loss), adjusted net income (loss) attributable to Huntsman Corporation and adjusted diluted income (loss) per share. The amounts for prior periods have been recast to conform to the current presentation.

Adjusted net income and adjusted income per share amounts are presented solely as supplemental information.

Three Months Ended March 31, 2013 Compared with Three Months Ended March 31, 2012

For the three months ended March 31, 2013, the net loss attributable to Huntsman Corporation was $24 million on revenues of $2,702 million, compared with net income attributable to Huntsman Corporation of $163 million on revenues of $2,913 million for the same period of 2012. For the three months ended March 31, 2013, the net loss attributable to Huntsman International was $23 million on revenues of $2,702 million, compared with net income attributable to Huntsman International of $166 million on revenues of $2,913 million for the same period of 2012. The decrease of $187 million in net (loss) income attributable to Huntsman Corporation and the decrease of $189 million in net (loss) income attributable to Huntsman International was the result of the following items:

•: Revenues for the three months ended March 31, 2013 decreased by $211 million, or 7%, as compared with the 2012 period. The decrease was due principally to lower average selling prices in our Textile Effects and Pigments segments and lower sales volumes in all of our segments, except Textile Effects. See "—Segment Analysis" below.
•: Our gross profit and the gross profit of Huntsman International for the three months ended March 31, 2013 decreased by $201 million each, or 37% and 36%, respectively, as compared with the 2012 period. The decrease resulted from lower gross margins in all of our segments. See "—Segment Analysis" below.
•: Operating expenses for the three months ended March 31, 2013 decreased by $10 million, or 4%, as compared with the 2012 period primarily related to an increase in foreign currency transaction gains.
•: Restructuring, impairment and plant closing costs for the three months ended March 31, 2013 increased to $44 million from nil in the 2012 period. For more information concerning

Table of Contents

restructuring activities, see "Note 6. Restructuring, Impairment and Plant Closing Costs" to our condensed consolidated financial statements (unaudited).

•: Our net interest expense and the net interest expense of Huntsman International for the three months ended March 31, 2013 decreased by $8 million and $7 million, or 14% and 11%, respectively, as compared with the 2012 period. The decrease is due principally to lower average debt balances.
•: Loss on early extinguishment of debt for the three months ended March 31, 2013 increased to $35 million from $1 million in the 2012 period as a result of higher repayments of indebtedness during the three months ended March 31, 2013 as compared to the 2012 period. During the three months ended March 31, 2013, we recorded a loss on early extinguishment of debt of $35 million primarily from the repurchase of the remainder of our 2016 Senior Notes. For more information, see "Note 7. Debt—Direct and Subsidiary Debt—Redemption of Notes and Loss on Early Extinguishment of Debt" to our condensed consolidated financial statements (unaudited).
•: Our income tax expense and the income tax expense of Huntsman International for the three months ended March 31, 2013 decreased by $80 million and $79 million, respectively, as compared with the same period in 2012, primarily due to decreased pre-tax income. Our tax expense is affected by the mix of income and losses in the tax jurisdictions in which we operate, as impacted by the presence of valuation allowances in certain tax jurisdictions. Our 2013 effective tax rate is significantly impacted by anticipated losses in tax jurisdictions where we have a full valuation allowance. For further information concerning taxes, see "Note 16. Income Taxes" to our condensed consolidated financial statements (unaudited).

Polyurethanes

The decrease in revenues in our Polyurethanes segment for the three months ended March 31, 2013 compared to the same period of 2012 was primarily due to lower sales volumes, partially offset by higher average selling prices. MDI sales volumes decreased in the European region, partially offset by increased sales volumes in the Asia Pacific and Americas regions. PO/MTBE sales volumes decreased primarily due to the timing of shipments. MDI average selling prices increased in all regions primarily in response to higher raw material costs. PO/MTBE average selling prices decreased primarily due to less favorable market conditions. The decrease in segment EBITDA was primarily due to lower PO/MTBE earnings (first quarter 2012 benefited from industry supply outages), partially offset by higher MDI margins and lower restructuring, impairment and plant closing costs. During the three months ended March 31, 2013 and 2012, our Polyurethanes segment recorded restructuring, impairment and plant closing costs of $1 million and $5 million, respectively. For more information concerning restructuring activities, see "Note 6. Restructuring, Impairment and Plant Closing Costs" to our condensed consolidated financial statements (unaudited).

Performance Products

The decrease in revenues in our Performance Products segment for the three months ended March 31, 2013 compared to the same period of 2012 was due to lower sales volumes partially offset by higher average selling prices. Sales volumes decreased by 18% as a result of scheduled maintenance on our olefins and ethylene oxide facilities in Port Neches, Texas in the first quarter of 2013. Excluding the

Table of Contents

impact of this scheduled maintenance, sales volumes would have increased by approximately 2%. Average selling prices increased primarily due to sales mix effect. The decrease in segment EBITDA was primarily due to the impact of our scheduled maintenance. As a result of lower upstream margins and lower product sales, we estimate the impact of this maintenance to be approximately $55 million on the first quarter of 2013. In addition, during the three months ended March 31, 2013, we recorded a restructuring charge of $2 million relating to planned personnel reductions in our Australian operations. For more information concerning restructuring activities, see "Note 6. Restructuring, Impairment and Plant Closing Costs" to our condensed consolidated financial statements (unaudited).

Advanced Materials

The decrease in revenues in our Advanced Materials segment for the three months ended March 31, 2013 compared to the same period of 2012 was primarily due to lower sales volumes. Sales volumes decreased in the European and Americas regions, primarily in our base resins and formulations businesses due to weaker demand and increased competition, while sales volumes in the Asia Pacific region increased primarily due to strong demand in the adhesives and electrical engineering markets. The decrease in segment EBITDA was primarily due to higher restructuring, impairment and plant closing costs, lower margins and lower sales volumes, partially offset by lower selling, general and administrative costs as a result of recent restructuring efforts. During the three months ended March 31, 2013 and 2012, our Advanced Materials segment recorded restructuring, impairment and plant closing costs of $21 million and $1 million, respectively. For more information concerning restructuring activities, see "Note 6. Restructuring, Impairment and Plant Closing Costs" to our condensed consolidated financial statements (unaudited).

Textile Effects

The increase in revenues in our Textile Effects segment for the three months ended March 31, 2013 compared to the same period of 2012 was due to higher sales volumes, partially offset by lower average selling prices. Sales volumes increased primarily due to increased market share in key markets. Average selling prices decreased primarily due to sales mix effect and foreign currency translation. The decrease in segment EBITDA was primarily due to higher restructuring, impairment and plant closing and transition costs and lower margins, partially offset by higher sales volumes and lower manufacturing and selling, general and administrative costs as a result of our restructuring efforts. During the three months ended March 31, 2013 and 2012, our Textile Effects segment recorded restructuring, impairment and plant closing and transition costs (credits) of $22 million and $(4) million, respectively. For more information concerning restructuring activities, see "Note 6. Restructuring, Impairment and Plant Closing Costs" to our condensed consolidated financial statements (unaudited).

Pigments

The decrease in revenues in our Pigments segment for the three months ended March 31, 2013 compared to the same period of 2012 was primarily due to lower average selling prices as sales volumes were essentially unchanged. Average selling prices decreased in all regions of the world primarily in response to lower end-use demand. The decrease in segment EBITDA was primarily due to lower margins and the impact of unabsorbed fixed costs at lower production rates.

Corporate and other

Corporate and other includes unallocated corporate overhead, unallocated foreign exchange gains and losses, LIFO inventory valuation reserve adjustments, loss on early extinguishment of debt, unallocated restructuring, impairment and plant closing costs, nonoperating income and expense, benzene sales and gains and losses on the disposition of corporate assets. For the three months ended

Table of Contents

March 31, 2013, EBITDA from Corporate and other for Huntsman Corporation decreased by $39 million to a loss of $80 million from a loss of $41 million for the same period in 2012. For the three months ended March 31, 2013, EBITDA from Corporate and other for Huntsman International decreased by $38 million to a loss of $79 million from a loss of $41 million for the same period in 2012. The decrease in EBITDA from Corporate and other for the three months ended March 31, 2013 resulted primarily from an increase in loss on early extinguishment of debt of $34 million ($35 million of loss in 2013 compared to $1 million of loss in 2012). For more information regarding the loss on early extinguishment of debt, see "Note 7. Debt—Direct and Subsidiary Debt—Redemption of Notes and Loss on Early Extinguishment of Debt" to our condensed consolidated financial statements (unaudited). The decrease in EBITDA also resulted from a $7 million increase in LIFO inventory valuation expense ($4 million of expense in 2013 compared to $3 million of income in 2012) and a $6 million decrease in income from benzene sales ($1 million loss in 2013 compared to $5 million gain in 2012). The decrease in EBITDA was partially offset by a decrease in unallocated foreign exchange losses of $5 million ($2 million gain in 2013 compared to $3 million loss in 2012) along with a decrease in incentive compensation of $4 million.

Discontinued Operations

The operating results of our former polymers, base chemicals and Australian styrenics businesses are classified as discontinued operations, and, accordingly, the revenues of these businesses are excluded from revenues for all periods presented. The EBITDA of these former businesses are included in discontinued operations for all periods presented. The loss from discontinued operations represents the operating results, legal costs, restructuring, impairment and plant closing costs and gain (loss) on disposal with respect to our former businesses.

LIQUIDITY AND CAPITAL RESOURCES

The following is a discussion of our liquidity and capital resources and does not include separate information with respect to Huntsman International in accordance with General Instructions H(1)(a) and (b) of Form 10-Q.

Cash

Net cash (used in) provided by operating activities for the three months ended March 31, 2013 and 2012 was $(74) million and $190 million, respectively. The decrease in net cash provided by operating activities during the three months ended March 31, 2013 compared with the same period in 2012 was primarily attributable to a decrease in operating income as described in "—Results of Operations" above and to a $25 million unfavorable variance in operating assets and liabilities for the three months ended March 31, 2013 as compared with the same period of 2012.

Net cash used in investing activities for the three months ended March 31, 2013 and 2012 was $85 million and $109 million, respectively. During the three months ended March 31, 2013 and 2012, we paid $89 million and $81 million, respectively, for capital expenditures. During the three months ended March 31, 2013 and 2012, we made investments in Louisiana Pigments Company, L.P. of $5 million and $34 million, respectively, and received dividends from Louisiana Pigments Company, L.P. of $15 million in each period. During the three months ended March 31, 2013 and 2012, we paid $7 million and $2 million, respectively, for the acquisition of businesses.

Net cash provided by (used in) financing activities for the three months ended March 31, 2013 and 2012 was $21 million and $(176) million, respectively. The increase in net cash provided by financing activities was primarily due to higher net borrowings of debt during the 2013 period as compared to the 2012 period, offset in part by an increase in dividends paid to common stockholders.

Our working capital decreased by $58 million as a result of the net impact of the following significant changes:

•: The decrease in cash and cash equivalents of $140 million resulted from the matters identified on our condensed consolidated statements of cash flows (unaudited).
•: Accounts receivable increased by $63 million mainly due to higher sales in March 2013, and longer payment terms by certain of our customers.
•: Inventories decreased by $22 million mainly due to lower inventory levels resulting primarily from scheduled maintenance at our Port Neches, Texas manufacturing facility during the first quarter of 2013.
•: Other current assets decreased by $18 million primarily due to lower bank accepted drafts with maturities greater than 90 days from receipt.
•: The decrease in accounts payable of $15 million was primarily due to lower cost of sales and lower inventory.
•: The decrease in accrued liabilities of $53 million was primarily due to payment of accrued interest, taxes other than income and accrued rebates, offset in part by an increase in current taxes payable.

loans or advances. In certain circumstances, the consent of a third party would be required prior to the transfer of any cash or assets from these subsidiaries to us.

Amendment to Credit Agreement

In connection with this debt repayment, we recognized a loss on early extinguishment of debt of approximately $1 million.

Senior Credit Facilities

As of March 31, 2013, our Senior Credit Facilities consisted of our Revolving Facility, Extended Term Loan B, our Extended Term Loan B—Series 2 and our Term Loan C as follows (dollars in millions):

(2): The applicable interest rate of the Senior Credit Facilities is subject to certain secured leverage ratio thresholds. As of March 31, 2013, the weighted average interest rate on our outstanding balances under the Senior Credit Facilities was approximately 3%.
(3): The maturity of the Revolving Facility commitments will accelerate if we do not repay, refinance or have a minimum level of liquidity available to enable us to repay our Term Loan C due June 30, 2016.

Our obligations under the Senior Credit Facilities are guaranteed by our Guarantors, and are secured by a first priority lien on substantially all of our domestic property, plant and equipment, the stock of all of our material domestic subsidiaries and certain foreign subsidiaries, and pledges of intercompany notes between certain of our subsidiaries.

Amendments to A/R Programs

On April 29, 2013, Huntsman International entered into an amendment to the U.S. A/R Program. This amendment, among other things, extends the scheduled commitment termination date of the U.S.

Variable Interest Entity Debt

Note Payable from Huntsman International to Huntsman Corporation

As of March 31, 2013, we have a loan of $840 million to our subsidiary, Huntsman International. The Intercompany Note is unsecured and $100 million of the outstanding amount is classified as current as of March 31, 2013 on our condensed consolidated balance sheets (unaudited). As of March 31, 2013, under the terms of the Intercompany Note, Huntsman International promises to pay us interest on the unpaid principal amount at a rate per annum based on the previous monthly average borrowing rate obtained under our U.S. A/R Program, less 10 basis points (provided that the rate shall not exceed an amount that is 25 basis points less than the monthly average borrowing rate obtained for the U.S. LIBOR-based borrowings under our Revolving Facility).

COMPLIANCE WITH COVENANTS

Our Senior Credit Facilities are subject to the Leverage Covenant which applies only to the Revolving Facility and is tested at the Huntsman International level. The Leverage Covenant is applicable only if borrowings, letters of credit or guarantees are outstanding under the Revolving Facility (cash collateralized letters of credit or guarantees are not deemed outstanding). The Leverage Covenant is a net senior secured leverage ratio covenant which requires that Huntsman International's ratio of senior secured debt to EBITDA (as defined in the applicable agreement) is not more than 3.75 to 1.

pay off the balance of the Senior Credit Facilities in full, and we may not have further access to such facilities.

SHORT-TERM AND LONG-TERM LIQUIDITY

We depend upon our cash, credit facilities, A/R Programs and other debt instruments to provide liquidity for our operations and working capital needs. As of March 31, 2013, we had $832 million of combined cash and unused borrowing capacity, consisting of $256 million in cash and restricted cash, $382 million in availability under our Revolving Facility, and $194 million in availability under our A/R Programs. Our liquidity can be significantly impacted by various factors. The following matters had, or are expected to have, a significant impact on our liquidity:

•: Our accounts receivable and inventory, net of accounts payable, increased by approximately $84 million for the three months ended March 31, 2013, as reflected in our condensed consolidated statements of cash flows (unaudited). We expect volatility in our working capital components to continue.
•: During 2013, we expect to spend approximately $450 million on capital expenditures. We expect to fund this spending with cash provided by operations.
•: During the three months ended March 31, 2013, we made contributions to our pension and postretirement benefit plans of $31 million. During 2013, we expect to contribute an additional amount of approximately $113 million to these plans.
•: We are also involved in a number of cost reduction programs for which we have established restructuring accruals. As of March 31, 2013, we had $115 million of accrued restructuring costs from continuing operations, and we expect to incur and pay additional restructuring and plant closing costs of up to approximately $81 million.

On September 8, 2009, we announced the closure of our styrenics facility located at West Footscray, Australia. We ceased the Australian styrenics operations during the first quarter of 2010. As of March 31, 2013, we had restructuring accruals of $6 million and environmental remediation accruals of approximately $29 million. We can provide no assurance that the eventual environmental remediation costs will not be materially different from our current estimate. The plant closure and environmental remediation costs are expected to be funded as they are incurred over the next several years.

•: We have in the past repurchased shares of our common stock. In the future, we could repurchase shares of our common stock from time to time without notice, through the open market or in privately negotiated transactions. Any such stock repurchases could impact our liquidity.

As of March 31, 2013, we had $298 million classified as current portion of debt including an HPS borrowing facility in China with $47 million outstanding, our scheduled Senior Credit Facilities amortization payments totaling $17 million, debt at our variable interest entities of $187 million and certain other short-term facilities and scheduled amortization payments totaling $47 million. Although we cannot provide assurances, we intend to renew or extend the majority of these short-term facilities in the current period.

Table of Contents

As of March 31, 2013, we had approximately $167 million of cash and cash equivalents, including restricted cash, held by our foreign subsidiaries, including our variable interest entities. Additionally, we have material intercompany debt obligations owed to us by our non-U.S. subsidiaries. We intend to use cash held in our foreign subsidiaries to fund our local operations. Nevertheless, we could repatriate cash as dividends or as repayments of intercompany debt. If foreign cash were repatriated as dividends, the dividends could be subject to adverse tax consequences. At present, we estimate that we will generate sufficient cash in our U.S. operations, together with the payments of intercompany debt, if necessary, to meet our cash needs in the U.S and we do not expect to repatriate cash to the U.S. as dividends. Cash held by certain foreign subsidiaries, including our variable interest entities, may also be subject to legal restrictions, including those arising from the interests of our partners, which could limit the amounts available for repatriation.

RESTRUCTURING, IMPAIRMENT AND PLANT CLOSING COSTS

Our Polyurethanes, Advanced Materials and Textile Effects segments are involved in cost reduction programs that are expected to reduce costs in these businesses by approximately $220 million. These cost savings are expected to be achieved through the middle of 2014. For further discussion of these plans and the costs involved, see "Note 6. Restructuring, Impairment and Plant Closing Costs" to our condensed consolidated financial statements (unaudited).

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

All derivatives, whether designated in hedging relationships or not, are recorded on our balance sheet at fair value. If the derivative is designated as a fair value hedge, the changes in the fair value of the derivative and the hedged items are recognized in earnings. If the derivative is designated as a cash flow hedge, changes in the fair value of the derivative are recorded in accumulated other comprehensive loss, to the extent effective, and will be recognized in the income statement when the hedged item affects earnings. To the extent applicable, we perform effectiveness assessments in order to

use hedge accounting at each reporting period. For a derivative that does not qualify as a hedge, changes in fair value are recognized in earnings.

sheets (unaudited). For the three months ended March 31, 2013, we recorded additional interest expense of nil due to changes in the fair value of the swap.

ITEM 4. CONTROLS AND PROCEDURES

Our management, with the participation of our chief executive officer and chief financial officer, has evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of March 31, 2013. Based on this evaluation, our chief executive officer and chief financial officer have concluded that, as of March 31, 2013, our disclosure controls and procedures were effective, in that they ensure that information required to be disclosed by

us in the reports that we file or submit under the Exchange Act is (1) recorded, processed, summarized and reported within the time periods specified in the Commission's rules and forms, and (2) accumulated and communicated to our management, including our chief executive officer and chief financial officer, as appropriate to allow timely decisions regarding required disclosure.

No changes to our internal control over financial reporting occurred during the quarter ended March 31, 2013 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act). However, we can only give reasonable assurance that our internal controls over financial reporting will prevent or detect material misstatements on a timely basis. Ineffective internal controls over financial reporting could cause investors to lose confidence in our reported financial information and could result in a lower trading price for our securities.
