	INTERIM FINANCIAL STATEMENTS	DESCRIPTION OF BUSINESS
	Our 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, 2013 for our Company.	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.
	DESCRIPTION OF BUSINESS	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.

	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. Intercompany accounts and transactions have been eliminated.
	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
	Performance Additives and Titanium Dioxide Acquisition
	On September 17, 2013, we entered into a definitive agreement (the "Stock Purchase Agreement") with Rockwood Holdings, Inc., which was amended on March 20, 2014. Pursuant to the Stock Purchase Agreement, as amended, we will acquire Rockwood's Performance Additives and Titanium Dioxide businesses for approximately $1.05 billion in cash, subject to certain purchase price adjustments, and the assumption of certain unfunded pension liabilities estimated at $225 million as of June 30, 2013. The transaction remains subject to regulatory approvals and customary closing conditions, and we continue to work with Rockwood and the regulatory authorities to close the transaction.
	Restructuring of European Surfactants Business
	On April 10, 2014, we announced that Wilmar Europe Holdings B.V. ("Wilmar") has agreed to purchase our European commodity surfactants business, including the ethoxylation facility in Lavera, France. In addition, Wilmar will enter into a multi-year arrangement to purchase sulphated surfactant products from our facilities in St. Mihiel, France and Castiglione Delle Stiviere, Italy. Completion of the sale remains subject to customary closing conditions, including regulatory procedures in France.
	In addition, we announced our intention to cease production at our Patrica, Italy surfactants facility by October 2014.

	2. RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS
	Accounting Pronouncements Adopted During 2014
	In February 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("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 adopted the amendments in this ASU effective January 1, 2014, and the initial adoption of the amendments in this ASU did not have any 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. We adopted the amendments in this ASU effective January 1, 2014, and the initial adoption of the amendments in this ASU did not have any impact on our condensed consolidated financial statements (unaudited).
	In July 2013, the FASB issued ASU No. 2013-11, Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists, providing guidance on the presentation of unrecognized tax benefits in the financial statements as either a reduction to a deferred tax asset or as a liability to better reflect the manner in which an entity would settle at the reporting date any additional income taxes that would result from the disallowance of a tax position when net operating loss carryforwards ("NOLs"), similar tax losses or tax credit carryforwards exist. The amendments in this ASU do not require new recurring disclosures. The amendments in this ASU are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. We adopted the amendments in this ASU effective January 1, 2014, and the initial adoption of the amendments in this ASU did not have any impact on our condensed consolidated financial statements (unaudited).
	Accounting Pronouncements Pending Adoption in Future Periods
	In April 2014, the FASB issued ASU No. 2014-08, Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity, changing the criteria for reporting discontinued operations and enhancing reporting requirements for discontinued operations. A disposal of a component of an entity or a group of components of an entity will be required to be reported in discontinued operations if the disposal represents a strategic shift that has (or will have) a major effect on an entity's operations and financial results. Further, the amendments in this ASU will require an entity to present, for each comparative period, the assets and liabilities of a disposal group that includes a discontinued operation separately in the asset and liability sections, respectively, of the statement of financial position. The amendments in this ASU are effective prospectively for all disposals (or classifications as held for sale) of components of an entity that occur within annual periods beginning on or after December 15, 2014, and interim periods within those years, and for all businesses that, on acquisition, are classified as held for sale that occur within annual periods beginning on or after December 15, 2014, and interim periods within those years. We do not expect the adoption of the amendments in this ASU to have a significant impact on our condensed consolidated financial statements (unaudited).

OXID ACQUISITION

PERFORMANCE ADDITIVES AND TITANIUM DIOXIDE ACQUISITION

On August 29, 2013, we completed the acquisition of the chemical business of Oxid L.P. (the "Oxid Acquisition"), a privately-held manufacturer and marketer of specialty urethane polyols based in Houston, Texas. The acquisition cost of approximately $76 million consists of cash payments of approximately $66 million and contingent consideration of $10 million. The contingent consideration relates to an earn-out agreement which will be paid over two years if certain conditions are met. Related to this earn-out agreement, $6 million was paid during the three months ended March 31, 2014. The acquired business has been integrated into our Polyurethanes segment. Transaction costs charged to expense related to this acquisition were not significant.

On September 17, 2013, we entered into a definitive agreement to acquire the Performance Additives and Titanium Dioxide businesses of Rockwood Holdings, Inc. for approximately $1.1 billion in cash, subject to certain purchase price adjustments, and the assumption of certain unfunded pension liabilities estimated at $225 million as of June 30, 2013. The transaction remains subject to regulatory approvals and customary closing conditions and is expected to close during the first half of 2014.

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

SALE OF STEREOLITHOGRAPHY RESIN AND DIGITALIS® MACHINE MANUFACTURING BUSINESSES

On November 1, 2011, our Advanced Materials division completed the sale of its stereolithography resin and Digitalis® machine manufacturing businesses to 3D Systems Corporation for $41 million in cash. The stereolithography business produced products that are used primarily in three-dimensional part building systems. The Digitalis® business is a stereolithography rapid manufacturing system that we were developing. In connection with this sale, we recognized a pre-tax gain in the fourth quarter of 2011 of $34 million which was reflected in other operating income in our consolidated statements of operations and comprehensive income (loss). We also derecognized $2 million of goodwill that was allocated to these businesses.

TEXTILE EFFECTS ACQUISITION

On June 30, 2006, we acquired Ciba's textile effects business and accounted for the Textile Effects Acquisition using the purchase method. As such, we analyzed the fair value of tangible and intangible assets acquired and liabilities assumed and determined the excess of fair value of net assets over cost. Because the fair value of the acquired assets and liabilities assumed exceeded the purchase price, the value of the long-lived assets acquired was reduced to zero. Accordingly, no basis was assigned to property, plant and equipment or any other non-current nonfinancial assets and the remaining excess was recorded as an extraordinary gain. During 2012 and 2011, we recorded an additional extraordinary gain on the acquisition of $2 million and $4 million, respectively, related to settlement of contingent purchase price consideration, the reversal of accruals for certain restructuring and employee termination costs recorded in connection with the Textile Effects Acquisition and a reimbursement by Ciba of certain costs pursuant to the acquisition agreements.

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, Arabian Amines Company settled a dispute with its contractors and received an amount totaling $11 million. Of this $11 million settlement, $8 million was related to damages incurred due to the delayed initial acceptance of the plant. This amount was recorded as other operating expense (income) in our consolidated statements of operations and included in cash flows from operating activities in our consolidated statements of cash flows. The remaining $3 million of the settlement was received for the reimbursement of capital expenditures for work left unfinished by the contractors. This amount was included in cash flows from investing activities in our consolidated statements of cash flows.

We do not guarantee these loan commitments, and Arabian Amines Company is not a guarantor of any of our other debt obligations. Arabian Amines Company's noncompliance with its financial covenants does not affect any of our debt obligations. While the lenders under the loan commitments have agreed to certain modifications, we continue discussions with Arabian Amines Company's lenders and expect to resolve the noncompliance.

The Intercompany Note is unsecured and $100 million of the outstanding amount is classified as current as of March 31, 2014 on our condensed consolidated balance sheets (unaudited). As of March 31, 2014, under the terms of the Intercompany Note, we promise to pay Huntsman Corporation 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).													-1
														The amount of actual availability under our A/R Programs may be lower based on the level of eligible receivables sold, changes in the credit ratings of our customers, customer concentration levels and certain characteristics of the accounts receivable being transferred, as defined in the applicable agreements.
	COMPLIANCE WITH COVENANTS
													-2
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 certain financial covenants contained under its loan commitments. See "—Variable Interest Entity Debt" above.													Each interest rate is defined in the applicable agreements. In addition, the U.S. SPE and the EU SPE are obligated to pay unused commitment fees to the lenders based on the amount of each lender's commitment.
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.													-3
													Applicable rate for our U.S. A/R Program is defined by the lender as USD LIBOR. Applicable rate for our EU A/R Program is either GBP LIBOR, USD LIBOR or EURIBOR.
Our Senior Credit Facilities are subject to a single financial covenant (the "Leverage Covenant") which applies only to the Revolving Facility. 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.
													-4
If in the future we fail to comply with the Leverage Covenant, then we may not have access to liquidity under our Revolving Facility. If we fail 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.													As of December 31, 2013, we had approximately $7 million (U.S. dollar equivalents) of letters of credit issued and outstanding under our U.S. A/R Program.
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.													As of December 31, 2013 and 2012, $521 million and $520 million, respectively, of accounts receivable were pledged as collateral under our A/R Programs.
													Amendments to A/R Programs
													On April 29, 2013, we entered into an amendment to the agreements governing our U.S. A/R Program. This amendment, among other things, extends the scheduled commitment termination date of our U.S. A/R Program by two years to April 2016, provides for additional availability under our U.S. A/R Program and reduces the applicable margin on borrowings to 1.10%.
													On April 29, 2013, we entered into an amendment to the agreements governing our EU A/R Program. This amendment, among other things, extends the scheduled commitment termination date of our EU A/R Program by two years to April 2016 and reduces the applicable margin on borrowings to 1.35%.

													The 2021 Senior Notes and 2020 Senior Notes are general unsecured senior obligations of us and are guaranteed on a general unsecured senior basis by the Guarantors. The indentures impose certain limitations on the ability of us and our 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 2021 Senior Notes and 2020 Senior Notes will have the right to require that we 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.

	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.	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. 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.
	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.	INTEREST RATE RISKS
	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.	Through our borrowing activities, we are exposed to interest rate risk. Such risk arises due to the structure of our debt portfolio, including the duration of the portfolio and the mix of fixed and floating interest rates. Actions taken to reduce interest rate risk include managing the mix and rate characteristics of various interest bearing liabilities, as well as entering into interest rate derivative instruments.
	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, 2014, we had approximately $201 million in notional amount (in U.S. dollar equivalents) outstanding in forward foreign currency contracts.	From time to time, we may purchase interest rate swaps and/or interest rate collars to reduce the impact of changes in interest rates on our floating-rate long-term debt. Under interest rate swaps, we agree with other parties to exchange, at specified intervals, the difference between fixed-rate and floating-rate interest amounts calculated by reference to an agreed notional principal amount. The collars entitle us to receive from the counterparties (major banks) the amounts, if any, by which our interest payments on certain of our floating-rate borrowings exceed a certain rate, and require us to pay to the counterparties (major banks) the amount, if any, by which our interest payments on certain of our floating-rate borrowings are less than a certain rate.
	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, 2014, the fair value of the hedge was $1 million and was recorded as a liability on our condensed consolidated balance sheets (unaudited).	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 income (loss). We will pay a fixed 2.6% on the hedge and receive the one-month LIBOR rate. As of December 31, 2013 and 2012, the fair value of the hedge was $1 million and $2 million, respectively, and was recorded in other noncurrent liabilities.
	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, 2014, the fair value of the hedge was $1 million and was recorded as a liability 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 in other comprehensive income (loss). We will pay a fixed 2.8% on the hedge and receive the one-month LIBOR rate. As of December 31, 2013 and 2012, the fair value of the hedge was $1 million and $3 million, respectively, and was recorded in other noncurrent liabilities.
	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, 2014, the combined fair value of these two hedges was $3 million and was recorded as a liability 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 hedges as of March 31, 2014 was €33 million (approximately $45 million) and the derivative transactions do not qualify for hedge accounting. As of March 31, 2014, the fair value of the hedges was €1 million (approximately $1 million) and was recorded as a liability on our condensed consolidated balance sheets (unaudited). For the three months ended March 31, 2014, we recorded a reduction of interest expense of nil due to changes in the fair value of the hedges.

For 2013 and 2012, we recorded a reduction of interest expense of € 1 million (approximately $2 million) and less than €1 million (approximately $1 million), respectively, 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, 2014 was $30 million, and the interest rate contract is not designated as a cash flow hedge.

	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, 2014, the fair value of this swap was $1 million and was recorded as an asset on our condensed consolidated balance sheets (unaudited).	For the years ended December 31, 2013 and 2012, the changes in accumulated other comprehensive gain (loss) associated with these cash flow hedging activities were approximately $3 million and $(1) million, respectively.
	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.	During 2014, accumulated other comprehensive loss of nil is expected to be reclassified to earnings. The actual amount that will be reclassified to earnings over the next twelve months may vary from this amount due to changing market conditions. We would be exposed to credit losses in the event of nonperformance by a counterparty to our derivative financial instruments. We anticipate, however, that the counterparties will be able to fully satisfy their obligations under the contracts. Market risk arises from changes in interest rates.
	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.	FOREIGN EXCHANGE RATE RISK
	We review our non-U.S. dollar denominated debt and derivative instruments to determine the appropriate amounts designated as hedges. As of March 31, 2014, we have designated approximately €505 million (approximately $695 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, 2014, the amount of gain recognized on the hedge of our net investment was less than $1 million and was recorded in other comprehensive income on our condensed consolidated statements of comprehensive income (unaudited). As of March 31, 2014, we had approximately €1,012 million (approximately $1,394 million) in net euro assets.	Our cash flows and earnings are subject to fluctuations due to exchange rate variation. Our revenues and expenses are denominated in various currencies. We 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 three months or less). We do not hedge our currency exposures in a manner that would eliminate the effect of changes in exchange rates on our cash flows and earnings. As of December 31, 2013 and 2012, we had approximately $193 million and $217 million notional amount (in U.S. dollar equivalents) outstanding, respectively, in foreign currency contracts with a term of approximately one month.
		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.

This swap is designated as a hedge of net investment for financial reporting purposes. As of December 31, 2013 and 2012, the fair value of this swap was $2 million and $18 million, respectively, and was recorded in noncurrent assets.
		A portion of our debt is denominated in euros. We also 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 (loss). 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 December 31, 2013, we have designated approximately €525 million (approximately $725 million) of euro-denominated debt and cross-currency interest rate contracts as a hedge of our net investment. For the years ended December 31, 2013, 2012 and 2011, the amount of gain (loss) recognized on the hedge of our net investment was $(22) million, $(11) million and $5 million, respectively, and was recorded in other comprehensive income (loss). As of December 31, 2013, we had approximately €988 million (approximately $1,364 million) in net euro assets.
		COMMODITY PRICES RISK
		Our exposure to changing commodity prices is somewhat limited since the majority of our raw materials are acquired at posted or market related prices, and sales prices for many of our finished products are at market related prices which are largely set on a monthly or quarterly basis in line with industry practice. Consequently, we do not generally hedge our commodity exposures.

													We are party to cross-currency interest rate contracts that are measured at fair value in our consolidated 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 2012, this credit valuation adjustment has 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 value in periods subsequent to their initial recognition is applicable if one or more is determined to be impaired. During 2013 and 2012, we had no impairments related to these assets.

													Our employees participate in a trusteed, non-contributory defined benefit pension plan (the "Plan") that covers substantially all of our full-time U.S. employees. Effective July 1, 2004, the Plan formula for employees not covered by a collective bargaining agreement was converted to a cash balance design. For represented employees, participation in the cash balance design is subject to the terms of negotiated contracts. For participating employees, benefits accrued under the prior formula were converted to opening cash balance accounts. The new cash balance benefit formula provides annual pay credits from 4% to 12% of eligible pay, depending on age and service, plus accrued interest. Participants in the plan on July 1, 2004 may be eligible for additional annual pay credits from 1% to 8%, depending on their age and service as of that date, for up to five years. The conversion to the cash balance plan did not have a significant impact on the accrued benefit liability, the funded status or ongoing pension expense.

												Our investment strategy with respect to pension assets is to pursue an investment plan that, over the long term, is expected to protect the funded status of the plan, enhance the real purchasing power of plan assets, and not threaten the plan's ability to meet currently committed obligations. Additionally, our investment strategy is to achieve returns on plan assets, subject to a prudent level of portfolio risk. Plan assets are invested in a broad range of investments. These investments are diversified in terms of domestic and international equities, both growth and value funds, including small, mid and large capitalization equities; short-term and long-term debt securities; real estate; and cash and cash equivalents. The investments are further diversified within each asset category. The portfolio diversification provides protection against a single investment or asset category having a disproportionate impact on the aggregate performance of the plan assets.
												Our pension plan assets are managed by outside investment managers. The investment managers value our plan assets using quoted market prices, other observable inputs or unobservable inputs. For certain assets, the investment managers obtain third-party appraisals at least annually, which use valuation techniques and inputs specific to the applicable property, market, or geographic location. During 2013, there were no transfers in or out of Level 3 assets.
												We have established target allocations for each asset category. Our pension plan assets are periodically rebalanced based upon our target allocations.
												The fair value of plan assets for the pension plans was $3.2 billion and $2.9 billion at December 31, 2013 and 2012, respectively. The following plan assets are measured at fair value on a recurring basis (dollars in millions):

												Based upon historical returns, the expectations of our investment committee and outside advisors, the expected long-term rate of return on the pension assets is estimated to be between 5.75% and 8.19%. The asset allocation for our pension plans at December 31, 2013 and 2012 and the target allocation for 2014, by asset category are as follows:

												Equity securities in our pension plans did not include any equity securities of our Company or our affiliates at the end of 2013.
												DEFINED CONTRIBUTION PLANS
												We have a money purchase pension plan covering substantially all of our domestic employees who were hired prior to January 1, 2004. Employer contributions are made based on a percentage of employees' earnings (ranging up to 8%).
												We also have a salary deferral plan covering substantially all U.S. employees. Plan participants may elect to make voluntary contributions to this plan up to a specified amount of their compensation. We contribute an amount equal to one-half of the participant's contribution, not to exceed 2% of the participant's compensation.
												Along with the introduction of the cash balance formula within our defined benefit pension plan, the money purchase pension plan was closed to new hires. At the same time, our match in the salary deferral plan was increased, for new hires, to a 100% match, not to exceed 4% of the participant's compensation, once the participant has achieved six years of service with our Company.
												Our total combined expense for the above defined contribution plans for each of the years ended December 31, 2013, 2012 and 2011 was $14 million.
												SUPPLEMENTAL SALARY DEFERRAL PLAN AND SUPPLEMENTAL EXECUTIVE RETIREMENT PLAN
												The Huntsman Supplemental Savings Plan ("Huntsman SSP") is a non-qualified plan covering key management employees and allows participants to defer amounts that would otherwise be paid as compensation. The participant can defer up to 75% of their salary and bonus each year. This plan also provides benefits that would be provided under the Huntsman Salary Deferral Plan if that plan were not subject to legal limits on the amount of contributions that can be allocated to an individual in a single year. The Huntsman SSP was amended and restated effective as of January 1, 2005 to allow eligible executive employees to comply with Section 409A of the Internal Revenue Code of 1986.
												The SERP is an unfunded non-qualified pension plan established to provide certain executive employees with benefits that could not be provided, due to legal limitations, under the Huntsman Defined Benefit Pension Plan, a qualified defined benefit pension plan, and the Huntsman Money Purchase Pension Plan, a qualified money purchase pension plan.
												Assets of these plans are included in other noncurrent assets and as of December 31, 2013 and 2012 were $21 million and $14 million, respectively. During each of the years ended December 31, 2013, 2012 and 2011, we expensed a total of $1 million as contributions to the Huntsman SSP and the SERP.
												STOCK-BASED INCENTIVE PLAN
												In connection with the initial public offering of common and preferred stock on February 16, 2005, we adopted the Huntsman Stock Incentive Plan (the "Stock Incentive Plan"). The Stock Incentive Plan permits the grant of non-qualified stock options, incentive stock options, stock appreciation rights, nonvested 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. As of December 31, 2013 we are authorized to grant up to 32.6 million shares under the Stock Incentive Plan. See "Note 21. Stock- Based Compensation Plan."
												INTERNATIONAL PLANS
												International employees are covered by various post-employment arrangements consistent with local practices and regulations. Such obligations are included in other long-term liabilities in our consolidated balance sheets.

	LEGAL MATTERS					PURCHASE COMMITMENTS
	Asbestos Litigation					We have various purchase commitments extending through 2029 for materials, supplies and services entered into in the ordinary course of business. Included in the purchase commitments table below are contracts which require minimum volume purchases that extend beyond one year or are renewable annually and have been renewed for 2014. Certain contracts allow for changes in minimum required purchase volumes in the event of a temporary or permanent shutdown of a facility. To the extent the contract requires a minimum notice period, such notice period has been included in the table below. The contractual purchase prices for substantially all of these contracts are variable based upon market prices, subject to annual negotiations. We have estimated our contractual obligations by using the terms of our current pricing for each contract. We also have a limited number of contracts which require a minimum payment even if no volume is purchased. We believe that all of our purchase obligations will be utilized in our normal operations. For the years ended December 31, 2013, 2012 and 2011, we made minimum payments of $7 million, nil and nil, respectively, under such take or pay contracts without taking the product.
	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 specific information about the amount of damages being sought, 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.					Total purchase commitments as of December 31, 2013 are as follows (dollars in millions):
	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. 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 twenty-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.
						Year ending December 31,
	The following table presents for the periods indicated certain information about cases for which service has been received that we have tendered to the indemnifying party, all of which have been accepted by the indemnifying party.					2014	$	1,315

	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.					OPERATING LEASES
	We have never made any payments with respect to these cases. As of March 31, 2014, 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, 2014.					We lease certain railcars, aircraft, equipment and facilities under long-term lease agreements. The total expense recorded under operating lease agreements in our consolidated statements of operations is approximately $80 million, $79 million and $83 million for 2013, 2012 and 2011, respectively, net of sublease rentals of approximately $4 million for each of 2013, 2012 and 2011.
	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. Cases include all cases for which service has been received by us. Certain prior cases that were filed in error against us have been dismissed.					Future minimum lease payments under operating leases as of December 31, 2013 are as follows (dollars in millions):

	We paid gross settlement costs for asbestos exposure cases that are not subject to indemnification of nil during each of the three months ended March 31, 2014 and 2013. As of March 31, 2014, we had an accrual of $425,000 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, 2014.						$	487
	Antitrust Matters					​	​	​
	We have been named as a defendant in consolidated 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 other defendants named in this matter are DuPont, Kronos and Cristal (formerly Millennium). On August 28, 2012, the court certified a class consisting of all U.S. customers who purchased titanium dioxide directly from the defendants (the "Direct Purchasers") since February 1, 2003. We and all other defendants settled the Direct Purchasers litigation and the court approved the settlement on December 13, 2013. We have paid the settlement in an amount immaterial to our condensed consolidated financial statements (unaudited).
	On November 22, 2013, we were named as a defendant in a civil antitrust suit filed in the U.S. District Court for the District of Minnesota brought by a Direct Purchaser who opted out of the Direct Purchasers class litigation (the "Opt Out Litigation"). On April 21, 2014, the court severed the claims against us from the other defendants and ordered our case transferred to the U.S. District Court for the Southern District of Texas. It is possible that additional claims will be filed by other Direct Purchasers who opted out of the class litigation.					Future minimum lease payments have not been reduced by minimum sublease rentals of $19 million due in the future under noncancelable subleases.
	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 the purchasers of products made from titanium dioxide (the "Indirect Purchasers") making essentially the same allegations as the Direct Purchasers. The Opt-Out Litigation and Indirect Purchasers plaintiffs seek to recover 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 which in the aggregate could be 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.					LEGAL MATTERS
	Product Delivery Claim					Asbestos Litigation
	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 $211 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 $156 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 our range of possible loss in this matter is between €0 and €113 million, and we have made no accrual with respect to this matter.					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 specific information about the amount of damages being sought, 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.
	Indemnification Matter					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. 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.
	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 have appealed to the Ninth Court of Appeals at Beaumont, Texas.					The following table presents for the periods indicated certain information about cases for which service has been received that we have tendered to the indemnifying party, all of which have been accepted by the indemnifying party.

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 clean-up 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 consolidated 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 several companies, including 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") in the U.S. 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 a 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, 2014, we had an accrued liability of approximately $24 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 required for 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, 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.

	Environmental Reserves	Environmental Reserves
	We have accrued liabilities relating to anticipated environmental clean-up 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 $28 million and $27 million for environmental liabilities as of March 31, 2014 and December 31, 2013, respectively. Of these amounts, $5 million was classified as accrued liabilities in our consolidated balance sheets as of both March 31, 2014 and December 31, 2013, and $23 million and $22 million were classified as other noncurrent liabilities in our consolidated balance sheets as of March 31, 2014 and December 31, 2013, 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	REGULATORY DEVELOPMENTS
	The European Union 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 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, our first phase registrations by the November 30, 2010 deadline and our second phase registrations by the May 31, 2013 deadline. While we continue our registration efforts to meet the next registration deadline of May 31, 2018, our REACH implementation team is now strategically focused on the evaluation and authorization phases 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 European Union, such as in Korea and Taiwan.

	Although the total long-term cost for REACH compliance is unknown at this time, we spent approximately $4 million, $8 million and $5 million in 2013, 2012 and 2011, 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	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 Durban negotiations of the Conference of the Parties to the Kyoto Protocol in 2012, a limited group of nations, including the European Union, 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 European Union, continues in its third phase. The European Union parliament continues with a process to formalized "backloading"—the withholding of GHG allowances to prop up carbon prices. In addition, the European Union has recently announced its intentions to cut GHG emissions to 40% below 1990 levels by 2040 and impose a 27% renewable energy requirement at the European Union level. In the U.S., California has commenced the first compliance period of its cap-and-trade program. In June 2013, China implemented its first pilot carbon emissions exchange in Shenzhen, China. Pilot carbon emissions schemes have also begun in Beijing, Shanghai, Guangdong, and Tianjin. Further expansion of China's regional cap-and-trade is planned, and ultimately it is expected that these regional systems will form the backbone of a national cap-and-trade program. As these programs have not been fully implemented and have experienced significant price volatility on low early trading volumes, we are unable at this time to determine their impact on our operations.

	Federal climate change legislation in the U.S. appears unlikely in the near-term. As a result, domestic efforts to curb GHG emissions will continue to be led by the U.S. Environmental Protection Agency's (the "EPA's") 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. Significant expansions of our existing facilities or construction of new facilities may be subject to the Clean Air Act's (the "CAA") Prevention of Significant Deterioration requirements under the EPA's GHG "Tailoring Rule." Some of our facilities are also subject to the EPA's Mandatory Reporting of Greenhouse Gases rule, and any further regulation 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 European Union 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 GHGs 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	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 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 provided a formal response to the DOJ and the EPA with a supplemental data submission on April 29, 2013. We have been engaged in discussions with the DOJ and the EPA regarding these alleged violations. We are currently unable to determine the likelihood or magnitude of potential penalty or injunctive relief that may be incurred in resolving this matter.

	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 an individual 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. These conclusions require significant judgment. In evaluating the objective evidence that historical results provide, we consider the cyclicality of our 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, 2014 and 2013, on a discrete basis, we released a valuation allowance of $4 million and $1 million, respectively, on certain net deferred tax assets in Luxembourg as a result of significant changes in estimated future taxable income resulting from increased intercompany debt and, therefore, increased interest income in Luxembourg.	The following is a summary of U.S. and non-U.S. provisions for current and deferred income taxes (dollars in millions):
	During the three months ended March 31, 2014 and 2013, for unrecognized tax benefits that impact tax expenses, we recorded a net increase in unrecognized tax benefits with a corresponding income tax expense of $3 million and $1 million, respectively. Additional decreases in unrecognized tax benefits were offset by cash settlements or increases in net deferred tax assets and, therefore, did not affect income tax expense.
			Year ended
	We recorded income tax (expense) benefit of $(37) million and $18 million for the three months ended March 31, 2014 and 2013, respectively. Our tax expense is significantly 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. Notably, we continue to earn a significant portion of our pre-tax income in the United States with an approximate 35% federal and state blended effective tax rate.		December 31,

		Total income tax expense	$	137		$	179		$	113
		Included in the non-U.S. deferred tax expense is a $22 million income tax benefit for losses from continuing operations for certain jurisdictions with valuation allowances to the extent that income was recorded in other comprehensive income in that same jurisdiction. This benefit in 2013 was largely attributable to Switzerland where changes in pension related items resulted in income in other comprehensive income (loss) and where we have a full valuation allowance against the net deferred tax asset. An offsetting income tax expense was recognized in accumulated other comprehensive loss.
		Included in the $14 million unrealized exchange gains and losses reconciliation item above is $10 million which occurred in Luxembourg where an offsetting valuation allowance was released.
		We operate in over 40 non-U.S. tax jurisdictions with no specific country earning a predominant amount of our off-shore earnings. While the vast majority of these countries have income tax rates that are lower than the U.S. statutory rate, the operating losses we incur in some of our non-U.S. jurisdictions results in a tax benefit for losses lower than the U.S. statutory rate and therefore mitigates or reverses the amount of tax rate benefit we would otherwise realize from these tax rate differentials. For the year ended December 31, 2013, this amount was an additional tax expense of $10 million, reflected in the reconciliation above.
		During 2013, we repatriated a significant amount of earnings to the U.S. from our Netherlands holding company, which included bringing onshore certain U.S. foreign tax credits. The foreign tax credits brought onshore significantly exceeded the amount needed to fully offset the cash tax impact of the dividend. After a net $9 million benefit for the utilization of foreign tax credits in 2013, a full valuation allowance was placed on the remaining foreign tax credits as it is currently more likely than not that the credits will expire unused due to a shortage of foreign source income for income tax purposes. These credits represent a potential future cash benefit to the Company and we intend to expend resources and explore changes to future business operations all of which could enable us to utilize the foreign tax credits and release the valuation allowance. This is a complex area of tax law subject to very specific factors and our ability to utilize these credits will likely have a significant impact on future income tax expense.
		During 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.

	Net deferred tax asset	$	(51	)	$	71
	We have NOLs of $3,189 million in various non-U.S. jurisdictions. While the majority of the non-U.S. NOLs have no expiration date, $923 million have a limited life (of which $860 million are subject to a valuation allowance) and $15 million are scheduled to expire in 2014 (all of which are subject to a valuation allowance). We had $15 million of NOLs expire unused in 2013 (all of which were subject to a valuation allowance).
	Included in the $3,189 million of non-U.S. NOLs is $758 million attributable to our Luxembourg entities. As of December 31, 2013, there is a valuation allowance of $180 million against these net tax-effected NOLs of $220 million. Due to the uncertainty surrounding the realization of the benefits of these losses, we have reduced the related deferred tax asset with a valuation allowance.
	Valuation allowances are reviewed each period on a tax jurisdiction by 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. 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 period limits our ability to consider other subjective evidence such as our projections for the future. Our judgments regarding valuation allowances are also influenced by the costs and risks associated with any tax planning idea.
	During 2013, we released valuations allowances of $16 million on a portion of our net deferred assets primarily in Luxembourg as a result of significant changes in estimated future taxable income resulting from increased intercompany debt and, therefore, increased interest income in Luxembourg.
	During 2012, we released valuation allowances of $24 million on a portion of our net deferred tax assets in China, in certain U.S. states and in Luxembourg, and we established valuation allowances of $23 million on certain net deferred tax assets in the U.S., India and Indonesia. Primarily as a result of a cumulative history of operating profits, we released the above noted valuation allowances in China and certain U.S. state tax jurisdictions. Additionally, a partial valuation allowance release was recognized in Luxembourg for $12 million as a result of significant changes in estimated future taxable income resulting from increased intercompany debt and, therefore, increased interest income in Luxembourg.
	During 2012, we amended certain prior year U.S. federal income tax filings and claimed $31 million of additional U.S. foreign tax credits. Due to uncertainty regarding our ability to actually utilize these credits before they expire in 2015, we established a partial valuation allowance of $21 million against the incremental deferred tax asset.
	During 2011, we released valuation allowances of $27 million on certain net deferred tax assets in France and Spain (as a result of recent profitability in our Pigments business), Singapore (as a result of a cumulative history of operating profits), Australia (as a result of discontinuing the unprofitable portion of the business operations in that country) and Luxembourg (as a result of significant changes in estimated future taxable income).
	Uncertainties regarding expected future income in certain jurisdictions could affect the realization of deferred tax assets in those jurisdictions and result in additional valuation allowances in future periods.
	The following is a summary of changes in the valuation allowance (dollars in millions):
		2013			2012			2011

	As of December 31, 2013 and 2012, the amount of unrecognized tax benefits which, if recognized, would affect the effective tax rate is $78 million and $37 million, respectively.
	In accordance with our accounting policy, we continue to recognize interest and penalties accrued related to unrecognized tax benefits in income tax expense.

	We conduct business globally and, as a result, we file income tax returns in U.S. federal, various U.S. state and various non-U.S. jurisdictions. The following table summarizes the tax years that remain subject to examination by major tax jurisdictions:
	Tax Jurisdiction	Open Tax Years
	China	2001 and later
	France	2002 and later
	India	2004 and later
	Italy	2009 and later
	Malaysia	2003 and later
	Switzerland	2007 and later
	The Netherlands	2007 and later
	United Kingdom	2011 and later
	United States federal	2012 and later
	Certain of our U.S. and non-U.S. income tax returns are currently under various stages of audit by applicable tax authorities and the amounts ultimately agreed upon in resolution of the issues raised may differ materially from the amounts accrued.
	We estimate that it is reasonably possible that certain of our non-U.S. unrecognized tax benefits could change within 12 months of the reporting date with a resulting decrease in the unrecognized tax benefits within a reasonably possible range of $3 million to $41 million. For the 12-month period from the reporting date, we would expect that a substantial portion of the decrease in our unrecognized tax benefits would result in a corresponding benefit to our income tax expense.
	During 2012, we concluded and settled tax examinations in the U.S. (both federal and various states) and various non-U.S. jurisdictions including, but not limited to, China, France and Italy. During 2012, we concluded and effectively settled tax examinations in the U.S. (both federal and various states) and various non-U.S. jurisdictions including, but not limited to, Hong Kong, Thailand and Japan. During 2011, we concluded and settled tax examinations in the U.S. (both federal and various states) and various non-U.S. jurisdictions including, but not limited to, Australia, China, France and Germany.
	For non-U.S. entities that were not treated as branches for U.S. tax purposes, we do not provide for income taxes on the undistributed earnings of these subsidiaries as earnings are reinvested and, in the opinion of management, will continue to be reinvested indefinitely. As discussed, we made a distribution of a portion of our earnings in 2013 when the amount of foreign tax credits associated with the distribution was greater than the amount of tax otherwise due. The undistributed earnings of foreign subsidiaries that are deemed to be permanently invested were approximately $194 million at December 31, 2013. It is not practicable to determine the unrecognized deferred tax liability on those earnings. We have material inter-company debt obligations owed by our non-U.S. subsidiaries to the U.S. We do not intend to repatriate earnings to the U.S. via dividend based on estimates of future domestic cash generation and our ability to return cash to the U.S. through payments of inter-company debt owned by our non-U.S. subsidiaries to the U.S. To the extent that cash is required in the U.S., rather than repatriate earnings to the U.S. via dividend, we expect to utilize our inter-company debt. If any earnings were repatriated via dividend, we would need to accrue and pay taxes on the distributions.

	INTERIM FINANCIAL STATEMENTS	DESCRIPTION OF BUSINESS
	Our 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, 2013 for our Company.	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.
	DESCRIPTION OF BUSINESS	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 limited liability company, was formed in 1999. We are a wholly-owned subsidiary of Huntsman Corporation.
	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. Intercompany accounts and transactions have been eliminated.
	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
	Performance Additives and Titanium Dioxide Acquisition
	On September 17, 2013, we entered into a definitive agreement (the "Stock Purchase Agreement") with Rockwood Holdings, Inc., which was amended on March 20, 2014. Pursuant to the Stock Purchase Agreement, as amended, we will acquire Rockwood's Performance Additives and Titanium Dioxide businesses for approximately $1.05 billion in cash, subject to certain purchase price adjustments, and the assumption of certain unfunded pension liabilities estimated at $225 million as of June 30, 2013. The transaction remains subject to regulatory approvals and customary closing conditions, and we continue to work with Rockwood and the regulatory authorities to close the transaction.
	Restructuring of European Surfactants Business
	On April 10, 2014, we announced that Wilmar Europe Holdings B.V. ("Wilmar") has agreed to purchase our European commodity surfactants business, including the ethoxylation facility in Lavera, France. In addition, Wilmar will enter into a multi-year arrangement to purchase sulphated surfactant products from our facilities in St. Mihiel, France and Castiglione Delle Stiviere, Italy. Completion of the sale remains subject to customary closing conditions, including regulatory procedures in France.
	In addition, we announced our intention to cease production at our Patrica, Italy surfactants facility by October 2014.
	For more information, see "Note 6. Restructuring, Impairment and Plant Closing Costs."

SUMMARY_OF_SIGNIFICANT_ACCOUNT

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	12 Months Ended
	Dec. 31, 2013
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	'
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	'
	2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	ASSET RETIREMENT OBLIGATIONS
	We accrue for asset retirement obligations, which consist primarily of landfill capping, closure and post-closure costs and asbestos abatement costs, in the period in which the obligations are incurred. Asset retirement obligations are accrued at estimated fair value. When the liability is initially recorded, we capitalize the cost by increasing the carrying amount of the related long- lived asset. Over time, the liability is accreted to its settlement value and the capitalized cost is depreciated over the useful life of the related asset. Upon settlement of the liability, we will recognize a gain or loss for any difference between the settlement amount and the liability recorded. Asset retirement obligations were $29 million and $28 million at December 31, 2013 and 2012, respectively.
	CARRYING VALUE OF LONG-LIVED ASSETS
	We review long-lived assets and all amortizable intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of these assets may not be recoverable. Recoverability is based upon current and anticipated undiscounted cash flows, and we recognize an impairment when such estimated cash flows are less than the carrying value of the asset. Measurement of the amount of impairment, if any, is based upon the difference between carrying value and fair value. Fair value is generally estimated by discounting estimated future cash flows using a discount rate commensurate with the risks involved. See "Note 11. Restructuring, Impairment and Plant Closing Costs."
	CASH AND CASH EQUIVALENTS
	We consider cash in checking accounts and cash in short-term highly liquid investments with remaining maturities of three months or less at the date of purchase, to be cash and cash equivalents. Cash flows from discontinued operations are not presented separately in our consolidated statements of cash flows.
	COST OF GOODS SOLD
	We classify the costs of manufacturing and distributing our products as cost of goods sold. Manufacturing costs include variable costs, primarily raw materials and energy, and fixed expenses directly associated with production. Manufacturing costs also include, among other things, plant site operating costs and overhead (including depreciation), production planning and logistics costs, repair and maintenance costs, plant site purchasing costs, and engineering and technical support costs. Distribution, freight and warehousing costs are also included in cost of goods sold.
	DERIVATIVES AND HEDGING ACTIVITIES
	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. Changes in the fair value of the hedge in the net investment of certain international operations are recorded in other comprehensive income (loss), to the extent effective. The effectiveness of a cash flow hedging relationship is established at the inception of the hedge, and after inception we perform effectiveness assessments at least every three months. A derivative designated as a cash flow hedge is determined to be effective if the change in value of the hedge divided by the change in value of the hedged item is within a range of 80% to 125%. Hedge ineffectiveness in a cash flow hedge occurs only if the cumulative gain or loss on the derivative hedging instrument exceeds the cumulative change in the expected future cash flows on the hedged transaction. For a derivative that does not qualify or has not been designated as a hedge, changes in fair value are recognized in earnings.
	ENVIRONMENTAL EXPENDITURES
	Environmental related restoration and remediation costs are recorded as liabilities when site restoration and environmental remediation and clean-up obligations are either known or considered probable and the related costs can be reasonably estimated. Other environmental expenditures that are principally maintenance or preventative in nature are recorded when expended and incurred and are expensed or capitalized as appropriate. See "Note 19. Environmental, Health and Safety Matters."
	FOREIGN CURRENCY TRANSLATION
	The accounts of our operating subsidiaries outside of the U.S., unless they are operating in highly inflationary economic environments, consider the functional currency to be the currency of the economic environment in which they operate. Accordingly, assets and liabilities are translated at rates prevailing at the balance sheet date. Revenues, expenses, gains and losses are translated at a weighted average rate for the period. Cumulative translation adjustments are recorded to equity as a component of accumulated other comprehensive loss.
	If a subsidiary operates in an economic environment that is considered to be highly inflationary (100% cumulative inflation over a three-year period), the U.S. dollar is considered to be the functional currency and gains and losses from remeasurement to the U.S. dollar from the local currency are included in the statement of operations. Where a subsidiary's operations are effectively run, managed, financed and contracted in U.S. dollars, such as certain finance subsidiaries outside of the U.S., the U.S. dollar is considered to be the functional currency.
	Foreign currency transaction gains and losses are recorded in other operating expense (income) in our consolidated statements of operations and were net losses of $11 million, $4 million and $3 million for the years ended December 31, 2013, 2012 and 2011, respectively.
	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 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.
	We do not provide for income taxes or benefits on the undistributed earnings of our non-U.S. subsidiaries as earnings are reinvested and, in the opinion of management, will continue to be reinvested indefinitely.
	Accounting for uncertainty in income taxes prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. The application of income tax law is inherently complex. We are required to determine if an income tax position meets the criteria of more-likely-than-not to be realized based on the merits of the position under tax law, in order to recognize an income tax benefit. This requires us to make significant judgments regarding the merits of income tax positions and the application of income tax law. Additionally, if a tax position meets the recognition criteria of more-likely-than-not we are required to make judgments and apply assumptions to measure the amount of the tax benefits to recognize. These judgments are based on the probability of the amount of tax benefits that would be realized if the tax position was challenged by the taxing authorities. Interpretations and guidance surrounding income tax laws and regulations change over time. As a consequence, changes in assumptions and judgments can materially affect amounts recognized in our consolidated financial statements.
	INTANGIBLE ASSETS AND GOODWILL
	Intangible assets are stated at cost (fair value at the time of acquisition) and are amortized using the straight-line method over the estimated useful lives or the life of the related agreement as follows:
	Patents and technology	5 - 30 years
	Trademarks	15 - 30 years
	Licenses and other agreements	5 - 15 years
	Other intangibles	5 - 15 years
	Goodwill represents costs in excess of fair values assigned to the underlying net assets of acquired businesses. Goodwill is not subject to any method of amortization, but is tested for impairment annually (at the beginning of the third quarter) and when events and circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. When the fair value is less than the carrying value of the related reporting unit, we are required to reduce the amount of goodwill through a charge to earnings. Fair value is estimated using the market approach, as well as the income approach based on discounted cash flow projections. Goodwill has been assigned to reporting units for purposes of impairment testing. Goodwill increased by $14 million during the year ended December 31, 2013 due to the finalization of purchase accounting.
	INVENTORIES
	Inventories are stated at the lower of cost or market, with cost determined using LIFO, first-in first-out, and average costs methods for different components of inventory.
	LEGAL COSTS
	We expense legal costs, including those legal costs incurred in connection with a loss contingency, as incurred.
	OTHER NONCURRENT ASSETS
	Other noncurrent assets consist primarily of spare parts, deferred debt issuance costs, the overfunded portion related to defined benefit plans for employees and capitalized turnaround costs. Debt issuance costs are amortized using the interest method over the term of the related debt.
	PRINCIPLES OF CONSOLIDATION
	Our consolidated financial statements 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.
	PROPERTY, PLANT AND EQUIPMENT
	Property, plant and equipment is stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives or lease term as follows:
	Buildings and equipment	5 - 50 years
	Plant and equipment	3 - 30 years
	Furniture, fixtures and leasehold improvements	5 - 20 years
	Interest expense capitalized as part of plant and equipment was $7 million, $4 million and $2 million for the years ended December 31, 2013, 2012 and 2011, respectively.
	Periodic maintenance and repairs applicable to major units of manufacturing facilities (a "turnaround") are accounted for on the deferral basis by capitalizing the costs of the turnaround and amortizing the costs over the estimated period until the next turnaround. Normal maintenance and repairs of plant and equipment are charged to expense as incurred. Renewals, betterments and major repairs that materially extend the useful life of the assets are capitalized, and the assets replaced, if any, are retired.
	REVENUE RECOGNITION
	We generate substantially all of our revenues through sales in the open market and long-term supply agreements. We recognize revenue when it is realized or realizable and earned. Revenue for product sales is recognized when a sales arrangement exists, risk and title to the product transfer to the customer, collectability is reasonably assured and pricing is fixed or determinable. The transfer of risk and title to the product to the customer usually occurs at the time shipment is made.
	Revenue arrangements that contain multiple deliverables, which relate primarily to licensing of technology, are evaluated to determine whether the arrangements should be divided into separate units of accounting and how the arrangement consideration should be measured and allocated among the separate units of accounting.
	SECURITIZATION OF ACCOUNTS RECEIVABLE
	Under our A/R Programs, we grant an undivided interest in certain of our trade receivables to the U.S. SPE and the EU SPE. This undivided interest serves as security for the issuance of debt. The A/R Programs provide for financing through a conduit program (in both U.S. dollars and euros). The amounts outstanding under our A/R Programs are accounted for as secured borrowings. See "Note 13. Debt—A/R Programs."
	STOCK-BASED COMPENSATION
	We measure the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award. That cost will be recognized over the period during which the employee is required to provide services in exchange for the award. See "Note 21. Stock-Based Compensation Plan."
	SUBSEQUENT EVENTS
	We have evaluated material subsequent events through the date these consolidated financial statements were issued.
	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.
	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 consolidated financial statements.
	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 in the notes to our consolidated financial statements. See "Note 22. Other Comprehensive Income (Loss)."
	In July 2013, the FASB issued ASU No. 2013-10, Derivatives and Hedging (Topic 815): Inclusion of the Fed Funds Effective Swap Rate (or Overnight Index Swap Rate) as a Benchmark Interest Rate for Hedge Accounting Purposes, permitting entities to use the Fed Funds Effective Swap Rate (OIS) as a U.S. benchmark interest rate for hedge accounting purposes under Topic 815, in addition to the U.S. Treasury rate and the London Interbank Offered Rate (LIBOR). The amendments also remove the restriction on using different benchmark rates for similar hedges. The amendments in this ASU were effective prospectively for qualifying new or redesignated hedging relationships entered into on or after July 17, 2013. We adopted the amendments in this ASU effective July 17, 2013, and the initial adoption of the amendments in this ASU did not have a significant impact on our consolidated financial statements.
	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 consolidated financial statements.
	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 consolidated financial statements.
	In July 2013, the FASB issued ASU No. 2013-11, Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists, providing guidance on the presentation of unrecognized tax benefits in the financial statements as either a reduction to a deferred tax asset or as a liability to better reflect the manner in which an entity would settle at the reporting date any additional income taxes that would result from the disallowance of a tax position when net operating loss carryforwards ("NOLs"), similar tax losses or tax credit carryforwards exist. The amendments in this ASU do not require new recurring disclosures. 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 prospectively to all unrecognized tax benefits that exist at the effective date. Retrospective application is permitted. We do not expect the adoption of the amendments in this ASU to have a significant impact on our consolidated financial statements.

OXID ACQUISITION

PERFORMANCE ADDITIVES AND TITANIUM DIOXIDE ACQUISITION

On August 29, 2013, we completed the acquisition of the chemical business of Oxid L.P. (the "Oxid Acquisition"), a privately-held manufacturer and marketer of specialty urethane polyols based in Houston, Texas. The acquisition cost of approximately $76 million consists of cash payments of approximately $66 million and contingent consideration of $10 million. The contingent consideration relates to an earn-out agreement which will be paid over two years if certain conditions are met. Related to this earn-out agreement, $6 million was paid during the three months ended March 31, 2014. The acquired business has been integrated into our Polyurethanes segment. Transaction costs charged to expense related to this acquisition were not significant.

On September 17, 2013, we entered into a definitive agreement to acquire the Performance Additives and Titanium Dioxide businesses of Rockwood Holdings, Inc. for approximately $1.1 billion in cash, subject to certain purchase price adjustments, and the assumption of certain unfunded pension liabilities estimated at $225 million as of June 30, 2013. The transaction remains subject to regulatory approvals and customary closing conditions and is expected to close during the first half of 2014.

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

SALE OF STEREOLITHOGRAPHY RESIN AND DIGITALIS® MACHINE MANUFACTURING BUSINESSES

On November 1, 2011, our Advanced Materials division completed the sale of its stereolithography resin and Digitalis® machine manufacturing businesses to 3D Systems Corporation for $41 million in cash. The stereolithography business produced products that are used primarily in three-dimensional part building systems. The Digitalis® business is a stereolithography rapid manufacturing system that we were developing. In connection with this sale, we recognized a pre-tax gain in the fourth quarter of 2011 of $34 million which was reflected in other operating income in our consolidated statements of operations and comprehensive income (loss). We also derecognized $2 million of goodwill that was allocated to these businesses.

TEXTILE EFFECTS ACQUISITION

On June 30, 2006, we acquired Ciba's textile effects business and accounted for the Textile Effects Acquisition using the purchase method. As such, we analyzed the fair value of tangible and intangible assets acquired and liabilities assumed and determined the excess of fair value of net assets over cost. Because the fair value of the acquired assets and liabilities assumed exceeded the purchase price, the value of the long-lived assets acquired was reduced to zero. Accordingly, no basis was assigned to property, plant and equipment or any other non-current nonfinancial assets and the remaining excess was recorded as an extraordinary gain. During 2012 and 2011, we recorded an additional extraordinary gain on the acquisition of $2 million and $4 million, respectively, related to settlement of contingent purchase price consideration, the reversal of accruals for certain restructuring and employee termination costs recorded in connection with the Textile Effects Acquisition and a reimbursement by Ciba of certain costs pursuant to the acquisition agreements.

						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.

						In April 2011, Arabian Amines Company settled a dispute with its contractors and received an amount totaling $11 million. Of this $11 million settlement, $8 million was related to damages incurred due to the delayed initial acceptance of the plant. This amount was recorded as other operating expense (income) in our consolidated statements of operations and included in cash flows from operating activities in our consolidated statements of cash flows. The remaining $3 million of the settlement was received for the reimbursement of capital expenditures for work left unfinished by the contractors. This amount was included in cash flows from investing activities in our consolidated statements of cash flows.
						Sasol-Huntsman had revenues and earnings of $116 million and $7 million, respectively, for the period from the date of consolidation to December 31, 2011.

	As of March 31, 2014, Arabian Amines Company had $166 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 certain financial covenants under its loan commitments. We do not guarantee these loan commitments, and Arabian Amines Company is not a guarantor of any of our other debt obligations. Arabian Amines Company's noncompliance with its financial covenants does not affect any of our debt obligations. While the lenders under the loan commitments have agreed to certain modifications, we continue discussions with Arabian Amines Company's lenders and expect to resolve the noncompliance. As of March 31, 2014, the amounts outstanding under these loan commitments were classified as current in our condensed consolidated balance sheets (unaudited).

	As of March 31, 2014, there was an $807 million loan outstanding owed by us to Huntsman Corporation (the "Intercompany Note"). The Intercompany Note is unsecured and $100 million of the outstanding amount is classified as current as of March 31, 2014 on our condensed consolidated balance sheets (unaudited). As of March 31, 2014, under the terms of the Intercompany Note, we promise to pay Huntsman Corporation 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).													-1
														The amount of actual availability under our A/R Programs may be lower based on the level of eligible receivables sold, changes in the credit ratings of our customers, customer concentration levels and certain characteristics of the accounts receivable being transferred, as defined in the applicable agreements.
	COMPLIANCE WITH COVENANTS
													-2
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 certain financial covenants contained under its loan commitments. See "—Variable Interest Entity Debt" above.													Each interest rate is defined in the applicable agreements. In addition, the U.S. SPE and the EU SPE are obligated to pay unused commitment fees to the lenders based on the amount of each lender's commitment.
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.													-3
													Applicable rate for our U.S. A/R Program is defined by the lender as USD LIBOR. Applicable rate for our EU A/R Program is either GBP LIBOR, USD LIBOR or EURIBOR.
Our Senior Credit Facilities are subject to a single financial covenant (the "Leverage Covenant") which applies only to the Revolving Facility. 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.
													-4
If in the future we fail to comply with the Leverage Covenant, then we may not have access to liquidity under our Revolving Facility. If we fail 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.													As of December 31, 2013, we had approximately $7 million (U.S. dollar equivalents) of letters of credit issued and outstanding under our U.S. A/R Program.
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.													As of December 31, 2013 and 2012, $521 million and $520 million, respectively, of accounts receivable were pledged as collateral under our A/R Programs.
													Amendments to A/R Programs
													On April 29, 2013, we entered into an amendment to the agreements governing our U.S. A/R Program. This amendment, among other things, extends the scheduled commitment termination date of our U.S. A/R Program by two years to April 2016, provides for additional availability under our U.S. A/R Program and reduces the applicable margin on borrowings to 1.10%.
													On April 29, 2013, we entered into an amendment to the agreements governing our EU A/R Program. This amendment, among other things, extends the scheduled commitment termination date of our EU A/R Program by two years to April 2016 and reduces the applicable margin on borrowings to 1.35%.

													The 2021 Senior Notes and 2020 Senior Notes are general unsecured senior obligations of us and are guaranteed on a general unsecured senior basis by the Guarantors. The indentures impose certain limitations on the ability of us and our 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 2021 Senior Notes and 2020 Senior Notes will have the right to require that we 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 December 31, 2013, Arabian Amines Company had $169 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 noncompliance 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 December 31, 2013, the amounts outstanding under these loan commitments were classified as current in our consolidated balance sheets and are comprised of the following:
													•
													A loan facility from Saudi Industrial Development Fund with SAR 451 million (approximately $120 million) outstanding. Repayment of the loan is to be made in semiannual installments with final maturity in 2019. The loan is secured by a mortgage over the fixed assets of the project and is 100% guaranteed by the Zamil Group, our 50% joint venture partner.

Obligations under the facility agreement are secured by, among other things, first priority right on the property, plant and equipment of Sasol-Huntsman.
													Other Debt
													During the year ended December 31, 2013, HPS repaid $4 million and RMB 293 million (approximately $47 million) on term loans and working capital loans under its secured facilities. As of December 31, 2013, HPS had $4 million and RMB 61 million (approximately $10 million) outstanding under its debt facilities. The interest rate on these facilities is LIBOR plus 0.48% for U.S. dollar borrowings and approximately 90% of the Peoples Bank of China rate for RMB borrowings. As of December 31, 2013, the interest rate was approximately 1% for the U.S. dollar borrowings and approximately 6% for RMB borrowings.
													As of December 31, 2013, HPS has RMB 160 million (approximately $26 million) under its loan facility for working capital loans and discounting of commercial drafts, which is classified as current portion of debt in our consolidated balance sheets.

	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.	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. 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.
	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.	INTEREST RATE RISKS
	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.	Through our borrowing activities, we are exposed to interest rate risk. Such risk arises due to the structure of our debt portfolio, including the duration of the portfolio and the mix of fixed and floating interest rates. Actions taken to reduce interest rate risk include managing the mix and rate characteristics of various interest bearing liabilities, as well as entering into interest rate derivative instruments.
	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, 2014, we had approximately $201 million in notional amount (in U.S. dollar equivalents) outstanding in forward foreign currency contracts.	From time to time, we may purchase interest rate swaps and/or interest rate collars to reduce the impact of changes in interest rates on our floating-rate long-term debt. Under interest rate swaps, we agree with other parties to exchange, at specified intervals, the difference between fixed-rate and floating-rate interest amounts calculated by reference to an agreed notional principal amount. The collars entitle us to receive from the counterparties (major banks) the amounts, if any, by which our interest payments on certain of our floating-rate borrowings exceed a certain rate, and require us to pay to the counterparties (major banks) the amount, if any, by which our interest payments on certain of our floating-rate borrowings are less than a certain rate.
	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, 2014, the fair value of the hedge was $1 million and was recorded as a liability on our condensed consolidated balance sheets (unaudited).	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 income (loss). We will pay a fixed 2.6% on the hedge and receive the one-month LIBOR rate. As of December 31, 2013 and 2012, the fair value of the hedge was $1 million and $2 million, respectively, and was recorded in other noncurrent liabilities.
	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 December 31, 2013 and 2012, the fair value of the hedge was $1 million and $3 million, respectively, and was recorded in other noncurrent liabilities.
	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, 2014, the combined fair value of these two hedges was $3 million and was recorded as a liability 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.

	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 hedges as of March 31, 2014 was €33 million (approximately $45 million) and the derivative transactions do not qualify for hedge accounting. As of March 31, 2014, the fair value of the hedges was €1 million (approximately $1 million) and was recorded as a liability on our condensed consolidated balance sheets (unaudited). For the three months ended March 31, 2014, we recorded a reduction of interest expense of nil due to changes in the fair value of the hedges.

For 2013 and 2012, we recorded a reduction of interest expense of € 1 million (approximately $2 million) and less than €1 million (approximately $1 million), respectively, 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, 2014 was $30 million, and the interest rate contract is not designated as a cash flow hedge. As of March 31, 2014, the fair value of the swap was $3 million and was recorded as a liability on our condensed consolidated balance sheets (unaudited). For the three months ended March 31, 2014, we recorded additional (reduction of) interest expense of nil due to changes in fair value of the swap.

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, 2014, the fair value of this swap was $1 million and was recorded as an asset on our condensed consolidated balance sheets (unaudited).	For the years ended December 31, 2013 and 2012, the changes in accumulated other comprehensive gain (loss) associated with these cash flow hedging activities were approximately $3 million and $(1) million, respectively.
	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.	During 2014, accumulated other comprehensive loss of nil is expected to be reclassified to earnings. The actual amount that will be reclassified to earnings over the next twelve months may vary from this amount due to changing market conditions. We would be exposed to credit losses in the event of nonperformance by a counterparty to our derivative financial instruments. We anticipate, however, that the counterparties will be able to fully satisfy their obligations under the contracts. Market risk arises from changes in interest rates.
	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.	FOREIGN EXCHANGE RATE RISK
	We review our non-U.S. dollar denominated debt and derivative instruments to determine the appropriate amounts designated as hedges. As of March 31, 2014, we have designated approximately €505 million (approximately $695 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, 2014, the amount of gain recognized on the hedge of our net investment was less than $1 million and was recorded in other comprehensive income on our condensed consolidated statements of comprehensive income (unaudited). As of March 31, 2014, we had approximately €1,012 million (approximately $1,394 million) in net euro assets.	Our cash flows and earnings are subject to fluctuations due to exchange rate variation. Our revenues and expenses are denominated in various currencies. We 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 three months or less). We do not hedge our currency exposures in a manner that would eliminate the effect of changes in exchange rates on our cash flows and earnings. As of December 31, 2013 and 2012, we had approximately $193 million and $217 million notional amount (in U.S. dollar equivalents) outstanding, respectively, in foreign currency contracts with a term of approximately one month.
		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 December 31, 2013 and 2012, the fair value of this swap was $2 million and $18 million, respectively, and was recorded in noncurrent assets.
		A portion of our debt is denominated in euros. We also 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 (loss). 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 December 31, 2013, we have designated approximately €525 million (approximately $725 million) of euro-denominated debt and cross-currency interest rate contracts as a hedge of our net investment. For the years ended December 31, 2013, 2012 and 2011, the amount of gain (loss) recognized on the hedge of our net investment was $(22) million, $(11) million and $5 million, respectively, and was recorded in other comprehensive income (loss). As of December 31, 2013, we had approximately €988 million (approximately $1,364 million) in net euro assets.
		COMMODITY PRICES RISK
		Our exposure to changing commodity prices is somewhat limited since the majority of our raw materials are acquired at posted or market related prices, and sales prices for many of our finished products are at market related prices which are largely set on a monthly or quarterly basis in line with industry practice. Consequently, we do not generally hedge our commodity exposures.

													We are party to cross-currency interest rate contracts that are measured at fair value in our consolidated 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 2012, this credit valuation adjustment has 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 value in periods subsequent to their initial recognition is applicable if one or more is determined to be impaired. During 2013 and 2012, we had no impairments related to these assets.

	Components of the net periodic benefit costs for the three months ended March 31, 2014 and 2013 were as follows (dollars in millions):												DEFINED BENEFIT AND OTHER POSTRETIREMENT BENEFIT PLANS
													Our employees participate in a trusteed, non-contributory defined benefit pension plan (the "Plan") that covers substantially all of our full-time U.S. employees. Effective July 1, 2004, the Plan formula for employees not covered by a collective bargaining agreement was converted to a cash balance design. For represented employees, participation in the cash balance design is subject to the terms of negotiated contracts. For participating employees, benefits accrued under the prior formula were converted to opening cash balance accounts. The new cash balance benefit formula provides annual pay credits from 4% to 12% of eligible pay, depending on age and service, plus accrued interest. Participants in the plan on July 1, 2004 may be eligible for additional annual pay credits from 1% to 8%, depending on their age and service as of that date, for up to five years. The conversion to the cash balance plan did not have a significant impact on the accrued benefit liability, the funded status or ongoing pension expense.

		Benefit Plans						Postretirement					During 2013, we amended the Plan which enabled us to transfer some benefit amounts out of the Huntsman Supplemental Executive Retirement Plan (the "SERP") to the Plan as permitted by the IRS rules.

	Service cost	$	15		$	17		$	1		$	1	Our postretirement benefit plans provide a fully insured Medicare Part D plan including prescription drug benefits affected by the Medicare Prescription Drug, Improvement and Modernization Act of 2003 (the "Act"). We cannot determine whether the medical benefits provided by our postretirement benefit plans are actuarially equivalent to those provided by the Act. We do not collect a subsidy and our net periodic postretirement benefits cost, and related benefit obligation, do not reflect an amount associated with the subsidy.

												Our investment strategy with respect to pension assets is to pursue an investment plan that, over the long term, is expected to protect the funded status of the plan, enhance the real purchasing power of plan assets, and not threaten the plan's ability to meet currently committed obligations. Additionally, our investment strategy is to achieve returns on plan assets, subject to a prudent level of portfolio risk. Plan assets are invested in a broad range of investments. These investments are diversified in terms of domestic and international equities, both growth and value funds, including small, mid and large capitalization equities; short-term and long-term debt securities; real estate; and cash and cash equivalents. The investments are further diversified within each asset category. The portfolio diversification provides protection against a single investment or asset category having a disproportionate impact on the aggregate performance of the plan assets.
												Our pension plan assets are managed by outside investment managers. The investment managers value our plan assets using quoted market prices, other observable inputs or unobservable inputs. For certain assets, the investment managers obtain third-party appraisals at least annually, which use valuation techniques and inputs specific to the applicable property, market, or geographic location. During 2013, there were no transfers in or out of Level 3 assets.
												We have established target allocations for each asset category. Our pension plan assets are periodically rebalanced based upon our target allocations.
												The fair value of plan assets for the pension plans was $3.2 billion and $2.9 billion at December 31, 2013 and 2012, respectively. The following plan assets are measured at fair value on a recurring basis (dollars in millions):

												Based upon historical returns, the expectations of our investment committee and outside advisors, the expected long-term rate of return on the pension assets is estimated to be between 5.75% and 8.19%.

												Equity securities in our pension plans did not include any equity securities of our Company or our affiliates at the end of 2013.
												DEFINED CONTRIBUTION PLANS
												We have a money purchase pension plan covering substantially all of our domestic employees who were hired prior to January 1, 2004. Employer contributions are made based on a percentage of employees' earnings (ranging up to 8%).
												We also have a salary deferral plan covering substantially all U.S. employees. Plan participants may elect to make voluntary contributions to this plan up to a specified amount of their compensation. We contribute an amount equal to one-half of the participant's contribution, not to exceed 2% of the participant's compensation.
												Along with the introduction of the cash balance formula within our defined benefit pension plan, the money purchase pension plan was closed to new hires. At the same time, our match in the salary deferral plan was increased, for new hires, to a 100% match, not to exceed 4% of the participant's compensation, once the participant has achieved six years of service with our Company.
												Our total combined expense for the above defined contribution plans for each of the years ended December 31, 2013, 2012 and 2011 was $14 million.
												SUPPLEMENTAL SALARY DEFERRAL PLAN AND SUPPLEMENTAL EXECUTIVE RETIREMENT PLAN
												The Huntsman Supplemental Savings Plan ("Huntsman SSP") is a non-qualified plan covering key management employees and allows participants to defer amounts that would otherwise be paid as compensation. The participant can defer up to 75% of their salary and bonus each year. This plan also provides benefits that would be provided under the Huntsman Salary Deferral Plan if that plan were not subject to legal limits on the amount of contributions that can be allocated to an individual in a single year. The Huntsman SSP was amended and restated effective as of January 1, 2005 to allow eligible executive employees to comply with Section 409A of the Internal Revenue Code of 1986.
												The SERP is an unfunded non-qualified pension plan established to provide certain executive employees with benefits that could not be provided, due to legal limitations, under the Huntsman Defined Benefit Pension Plan, a qualified defined benefit pension plan, and the Huntsman Money Purchase Pension Plan, a qualified money purchase pension plan.
												Assets of these plans are included in other noncurrent assets and as of December 31, 2013 and 2012 were $21 million and $14 million, respectively. During each of the years ended December 31, 2013, 2012 and 2011, we expensed a total of $1 million as contributions to the Huntsman SSP and the SERP.
												STOCK-BASED INCENTIVE PLAN
												In connection with the initial public offering of common and preferred stock on February 16, 2005, we adopted the Huntsman Stock Incentive Plan (the "Stock Incentive Plan"). The Stock Incentive Plan permits the grant of non-qualified stock options, incentive stock options, stock appreciation rights, nonvested 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. As of December 31, 2013 we are authorized to grant up to 32.6 million shares under the Stock Incentive Plan. See "Note 21. Stock- Based Compensation Plan."
												INTERNATIONAL PLANS
												International employees are covered by various post-employment arrangements consistent with local practices and regulations. Such obligations are included in other long-term liabilities in our consolidated balance sheets.

	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 an individual 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. These conclusions require significant judgment. In evaluating the objective evidence that historical results provide, we consider the cyclicality of our 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, 2014 and 2013, on a discrete basis, we released a valuation allowance of $4 million and $1 million, respectively, on certain net deferred tax assets in Luxembourg as a result of significant changes in estimated future taxable income resulting from increased intercompany debt and, therefore, increased interest income in Luxembourg.	The following is a summary of U.S. and non-U.S. provisions for current and deferred income taxes (dollars in millions):
	During the three months ended March 31, 2014 and 2013, for unrecognized tax benefits that impact tax expenses, we recorded a net increase in unrecognized tax benefits with a corresponding income tax expense of $3 million and $1 million, respectively. Additional decreases in unrecognized tax benefits were offset by cash settlements or increases in net deferred tax assets and, therefore, did not affect income tax expense.
			Year ended
	We recorded income tax (expense) benefit of $(37) million and $18 million for the three months ended March 31, 2014 and 2013, respectively. Our tax expense is significantly 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. Notably, we continue to earn a significant portion of our pre-tax income in the United States with an approximate 35% federal and state blended effective tax rate.		December 31,

		Total income tax expense	$	137		$	179		$	113
		Included in the non-U.S. deferred tax expense is a $22 million income tax benefit for losses from continuing operations for certain jurisdictions with valuation allowances to the extent that income was recorded in other comprehensive income in that same jurisdiction. This benefit in 2013 was largely attributable to Switzerland where changes in pension related items resulted in income in other comprehensive income (loss) and where we have a full valuation allowance against the net deferred tax asset. An offsetting income tax expense was recognized in accumulated other comprehensive loss.
		Included in the $14 million unrealized exchange gains and losses reconciliation item above is $10 million which occurred in Luxembourg where an offsetting valuation allowance was released.
		We operate in over 40 non-U.S. tax jurisdictions with no specific country earning a predominant amount of our off-shore earnings. While the vast majority of these countries have income tax rates that are lower than the U.S. statutory rate, the operating losses we incur in some of our non-U.S. jurisdictions results in a tax benefit for losses lower than the U.S. statutory rate and therefore mitigates or reverses the amount of tax rate benefit we would otherwise realize from these tax rate differentials. For the year ended December 31, 2013, this amount was an additional tax expense of $10 million, reflected in the reconciliation above.
		During 2013, we repatriated a significant amount of earnings to the U.S. from our Netherlands holding company, which included bringing onshore certain U.S. foreign tax credits. The foreign tax credits brought onshore significantly exceeded the amount needed to fully offset the cash tax impact of the dividend. After a net $9 million benefit for the utilization of foreign tax credits in 2013, a full valuation allowance was placed on the remaining foreign tax credits as it is currently more likely than not that the credits will expire unused due to a shortage of foreign source income for income tax purposes. These credits represent a potential future cash benefit to the Company and we intend to expend resources and explore changes to future business operations all of which could enable us to utilize the foreign tax credits and release the valuation allowance. This is a complex area of tax law subject to very specific factors and our ability to utilize these credits will likely have a significant impact on future income tax expense.
		During 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.

	We have NOLs of $3,189 million in various non-U.S. jurisdictions. While the majority of the non-U.S. NOLs have no expiration date, $923 million have a limited life (of which $860 million are subject to a valuation allowance) and $15 million are scheduled to expire in 2014 (all of which are subject to a valuation allowance). We had $15 million of NOLs expire unused in 2013 (all of which were subject to a valuation allowance).
	Included in the $3,189 million of non-U.S. NOLs is $758 million attributable to our Luxembourg entities. As of December 31, 2013, there is a valuation allowance of $180 million against these net tax-effected NOLs of $220 million. Due to the uncertainty surrounding the realization of the benefits of these losses, we have reduced the related deferred tax asset with a valuation allowance.
	Valuation allowances are reviewed each period on a tax jurisdiction by 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. 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 period limits our ability to consider other subjective evidence such as our projections for the future. Our judgments regarding valuation allowances are also influenced by the costs and risks associated with any tax planning idea.
	During 2013, we released valuations allowances of $16 million on a portion of our net deferred assets primarily in Luxembourg as a result of significant changes in estimated future taxable income resulting from increased intercompany debt and, therefore, increased interest income in Luxembourg.
	During 2012, we released valuation allowances of $24 million on a portion of our net deferred tax assets in China, in certain U.S. states and in Luxembourg, and we established valuation allowances of $23 million on certain net deferred tax assets in the U.S., India and Indonesia. Primarily as a result of a cumulative history of operating profits, we released the above noted valuation allowances in China and certain U.S. state tax jurisdictions. Additionally, a partial valuation allowance release was recognized in Luxembourg for $12 million as a result of significant changes in estimated future taxable income resulting from increased intercompany debt and, therefore, increased interest income in Luxembourg.
	During 2012, we amended certain prior year U.S. federal income tax filings and claimed $31 million of additional U.S. foreign tax credits. Due to uncertainty regarding our ability to actually utilize these credits before they expire in 2015, we established a partial valuation allowance of $21 million against the incremental deferred tax asset.
	During 2011, we released valuation allowances of $27 million on certain net deferred tax assets in France and Spain (as a result of recent profitability in our Pigments business), Singapore (as a result of a cumulative history of operating profits), Australia (as a result of discontinuing the unprofitable portion of the business operations in that country) and Luxembourg (as a result of significant changes in estimated future taxable income).
	Uncertainties regarding expected future income in certain jurisdictions could affect the realization of deferred tax assets in those jurisdictions and result in additional valuation allowances in future periods.
	The following is a summary of changes in the valuation allowance (dollars in millions):
		2013			2012			2011

	We conduct business globally and, as a result, we file income tax returns in U.S. federal, various U.S. state and various non-U.S. jurisdictions. The following table summarizes the tax years that remain subject to examination by major tax jurisdictions:
	Tax Jurisdiction	Open Tax Years
	China	2001 and later
	France	2002 and later
	India	2004 and later
	Italy	2009 and later
	Malaysia	2003 and later
	Switzerland	2007 and later
	The Netherlands	2007 and later
	United Kingdom	2011 and later
	United States federal	2012 and later
	Certain of our U.S. and non-U.S. income tax returns are currently under various stages of audit by applicable tax authorities and the amounts ultimately agreed upon in resolution of the issues raised may differ materially from the amounts accrued.
	We estimate that it is reasonably possible that certain of our non-U.S. unrecognized tax benefits could change within 12 months of the reporting date with a resulting decrease in the unrecognized tax benefits within a reasonably possible range of $3 million to $41 million. For the 12-month period from the reporting date, we would expect that a substantial portion of the decrease in our unrecognized tax benefits would result in a corresponding benefit to our income tax expense.
	During 2012, we concluded and settled tax examinations in the U.S. (both federal and various states) and various non-U.S. jurisdictions including, but not limited to, China, France and Italy. During 2012, we concluded and effectively settled tax examinations in the U.S. (both federal and various states) and various non-U.S. jurisdictions including, but not limited to, Hong Kong, Thailand and Japan. During 2011, we concluded and settled tax examinations in the U.S. (both federal and various states) and various non-U.S. jurisdictions including, but not limited to, Australia, China, France and Germany.
	For non-U.S. entities that were not treated as branches for U.S. tax purposes, we do not provide for income taxes on the undistributed earnings of these subsidiaries as earnings are reinvested and, in the opinion of management, will continue to be reinvested indefinitely. As discussed, we made a distribution of a portion of our earnings in 2013 when the amount of foreign tax credits associated with the distribution was greater than the amount of tax otherwise due. The undistributed earnings of foreign subsidiaries that are deemed to be permanently invested were approximately $194 million at December 31, 2013. It is not practicable to determine the unrecognized deferred tax liability on those earnings. We have material inter-company debt obligations owed by our non-U.S. subsidiaries to the U.S. We do not intend to repatriate earnings to the U.S. via dividend based on estimates of future domestic cash generation and our ability to return cash to the U.S. through payments of inter-company debt owned by our non-U.S. subsidiaries to the U.S. To the extent that cash is required in the U.S., rather than repatriate earnings to the U.S. via dividend, we expect to utilize our inter-company debt. If any earnings were repatriated via dividend, we would need to accrue and pay taxes on the distributions.

	LEGAL MATTERS					PURCHASE COMMITMENTS
	Asbestos Litigation					We have various purchase commitments extending through 2029 for materials, supplies and services entered into in the ordinary course of business. Included in the purchase commitments table below are contracts which require minimum volume purchases that extend beyond one year or are renewable annually and have been renewed for 2014. Certain contracts allow for changes in minimum required purchase volumes in the event of a temporary or permanent shutdown of a facility. To the extent the contract requires a minimum notice period, such notice period has been included in the table below. The contractual purchase prices for substantially all of these contracts are variable based upon market prices, subject to annual negotiations. We have estimated our contractual obligations by using the terms of our current pricing for each contract. We also have a limited number of contracts which require a minimum payment even if no volume is purchased. We believe that all of our purchase obligations will be utilized in our normal operations. For the years ended December 31, 2013, 2012 and 2011, we made minimum payments of $7 million, nil and nil, respectively, under such take or pay contracts without taking the product.
	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 specific information about the amount of damages being sought, 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.					Total purchase commitments as of December 31, 2013 are as follows (dollars in millions):
	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. 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 twenty-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.
						Year ending December 31,

	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.					OPERATING LEASES
	We have never made any payments with respect to these cases. As of March 31, 2014, 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, 2014.					We lease certain railcars, aircraft, equipment and facilities under long-term lease agreements. The total expense recorded under operating lease agreements in our consolidated statements of operations is approximately $80 million, $79 million and $83 million for 2013, 2012 and 2011, respectively, net of sublease rentals of approximately $4 million for each of 2013, 2012 and 2011.
	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. Cases include all cases for which service has been received by us. Certain prior cases that were filed in error against us have been dismissed.					Future minimum lease payments under operating leases as of December 31, 2013 are as follows (dollars in millions):

	We paid gross settlement costs for asbestos exposure cases that are not subject to indemnification of nil during each of the three months ended March 31, 2014 and 2013. As of March 31, 2014, we had an accrual of $425,000 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.

	Antitrust Matters					​	​	​
	We have been named as a defendant in consolidated 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 other defendants named in this matter are DuPont, Kronos and Cristal (formerly Millennium). On August 28, 2012, the court certified a class consisting of all U.S. customers who purchased titanium dioxide directly from the defendants (the "Direct Purchasers") since February 1, 2003. We and all other defendants settled the Direct Purchasers litigation and the court approved the settlement on December 13, 2013. We have paid the settlement in an amount immaterial to our condensed consolidated financial statements (unaudited).
	On November 22, 2013, we were named as a defendant in a civil antitrust suit filed in the U.S. District Court for the District of Minnesota brought by a Direct Purchaser who opted out of the Direct Purchasers class litigation (the "Opt Out Litigation"). On April 21, 2014, the court severed the claims against us from the other defendants and ordered our case transferred to the U.S. District Court for the Southern District of Texas. It is possible that additional claims will be filed by other Direct Purchasers who opted out of the class litigation.					Future minimum lease payments have not been reduced by minimum sublease rentals of $19 million due in the future under noncancelable subleases.
	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 the purchasers of products made from titanium dioxide (the "Indirect Purchasers") making essentially the same allegations as the Direct Purchasers. The Opt-Out Litigation and Indirect Purchasers plaintiffs seek to recover 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 which in the aggregate could be 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.					LEGAL MATTERS
	Product Delivery Claim					Asbestos Litigation
	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 $211 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 $156 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 our range of possible loss in this matter is between €0 and €113 million, and we have made no accrual with respect to this matter.					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 specific information about the amount of damages being sought, 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.
	Indemnification Matter					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. 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.
	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 have appealed to the Ninth Court of Appeals at Beaumont, Texas.					The following table presents for the periods indicated certain information about cases for which service has been received that we have tendered to the indemnifying party, all of which have been accepted by the indemnifying party.

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 in the U.S. 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 clean-up 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 condensed consolidated financial statements (unaudited).

	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 several companies, including 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.	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 several companies, including a predecessor company to us. In 2004, the U.S. Forest Service notified us that we are a CERCLA PRP for contamination originating from the site.

	In addition, under the Resource Conservation and Recovery Act ("RCRA") in the U.S. 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 a 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, 2014, we had an accrued liability of approximately $24 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 required for 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, 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.

	We have accrued liabilities relating to anticipated environmental clean-up 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 $28 million and $27 million for environmental liabilities as of March 31, 2014 and December 31, 2013, respectively. Of these amounts, $5 million was classified as accrued liabilities in our consolidated balance sheets as of both March 31, 2014 and December 31, 2013, and $23 million and $22 million were classified as other noncurrent liabilities in our consolidated balance sheets as of March 31, 2014 and December 31, 2013, 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	REGULATORY DEVELOPMENTS
	The European Union 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 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, our first phase registrations by the November 30, 2010 deadline and our second phase registrations by the May 31, 2013 deadline. While we continue our registration efforts to meet the next registration deadline of May 31, 2018, our REACH implementation team is now strategically focused on the evaluation and authorization phases 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 European Union, such as in Korea and Taiwan.

	Although the total long-term cost for REACH compliance is unknown at this time, we spent approximately $4 million, $8 million and $5 million in 2013, 2012 and 2011, 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	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 Durban negotiations of the Conference of the Parties to the Kyoto Protocol in 2012, a limited group of nations, including the European Union, 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 European Union, continues in its third phase. The European Union parliament continues with a process to formalized "backloading"—the withholding of GHG allowances to prop up carbon prices. In addition, the European Union has recently announced its intentions to cut GHG emissions to 40% below 1990 levels by 2040 and impose a 27% renewable energy requirement at the European Union level. In the U.S., California has commenced the first compliance period of its cap-and-trade program. In June 2013, China implemented its first pilot carbon emissions exchange in Shenzhen, China. Pilot carbon emissions schemes have also begun in Beijing, Shanghai, Guangdong, and Tianjin. Further expansion of China's regional cap-and-trade is planned, and ultimately it is expected that these regional systems will form the backbone of a national cap-and-trade program. As these programs have not been fully implemented and have experienced significant price volatility on low early trading volumes, we are unable at this time to determine their impact on our operations.

	Federal climate change legislation in the U.S. appears unlikely in the near-term. As a result, domestic efforts to curb GHG emissions will continue to be led by the U.S. Environmental Protection Agency's (the "EPA's") 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. Significant expansions of our existing facilities or construction of new facilities may be subject to the Clean Air Act's (the "CAA") Prevention of Significant Deterioration requirements under the EPA's GHG "Tailoring Rule." Some of our facilities are also subject to the EPA's Mandatory Reporting of Greenhouse Gases rule, and any further regulation 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 European Union 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 GHGs 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	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 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 provided a formal response to the DOJ and the EPA with a supplemental data submission on April 29, 2013. We have been engaged in discussions with the DOJ and the EPA regarding these alleged violations. We are currently unable to determine the likelihood or magnitude of potential penalty or injunctive relief that may be incurred in resolving this matter.

As of March 31, 2014, there was $36 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 2.2 years. The value of share awards that vested during the three months ended March 31, 2014 and 2013 was $19 million and $17 million, respectively.

	Pursuant to an agreement entered into in 2001, our subsidiary Airstar Corporation ("Airstar") subleases a Gulfstream IV-SP Aircraft (the "Aircraft") from Jstar Corporation ("Jstar"), a corporation wholly owned by Jon M. Huntsman. Jon M. Huntsman is the Executive Chairman and the father of our Chief Executive Officer, Peter R. Huntsman, and our director, Jon M. Huntsman, Jr. In 2011, this arrangement was extended for an additional 10 year period. Under this arrangement, monthly sublease payments from Airstar to Jstar are approximately $115,000, and an aggregate of $11 million is payable through the end of the remaining eight year lease term. These monthly sublease payments are used to fund financing costs paid by Jstar to a leasing company. An unrelated third party pays $2.4 million per year to our subsidiary for such third party's part-time use of the Aircraft (or an alternate owned by us if the Aircraft is unavailable), subject to an annual adjustment, which typically has been at least fair market value for the number of flight hours used by such third party. We bear all other costs of operating the Aircraft. In accordance with our Aircraft Use Policy, we have entered into aircraft time-sharing agreements with certain members of the Huntsman family, pursuant to which these persons pay for the costs of any personal use of the Aircraft by them.
	An agreement was reached prior to the initial public offering of our common stock in February 2005 with the Huntsman Foundation, a private charitable foundation established by Jon M. and Karen H. Huntsman, to further the charitable interests of the Huntsman family, that we would donate our Salt Lake City office building and our option to acquire an adjacent undeveloped parcel of land to the foundation free of debt. On March 24, 2010, we completed this donation. At the time of the donation, the building had an appraised value of approximately $10 million. We continue to occupy and use a portion of the building under a lease pursuant to which we make annual lease payments of approximately $2 million to the Huntsman Foundation. During each of the years ended 2013, 2012 and 2011, we made payments of approximately $2 million to the Huntsman Foundation under the lease. The lease expires on December 31, 2018, subject to a five-year extension, at our option.
	Through May 2002, we paid the premiums on various life insurance policies for Jon M. Huntsman. These policies have been liquidated, and the cash values have been paid to Mr. Huntsman. Mr. Huntsman is indebted to us in the amount of approximately $2 million with accrued interest, which represents the insurance premiums paid on his behalf through May 2002. This amount is included in other noncurrent assets in our consolidated balance sheets.

	During 2012, our Polyurethanes segment implemented a restructuring program to reduce annualized fixed costs. In connection with this program, we recorded restructuring expenses of $5 million, $32 million and $1 million in the first, third and fourth quarters of 2012, respectively.
	-2
	During the fourth quarter of 2012, our Advanced Materials segment began implementing a global transformational change program, subject to consultation with relevant employee representatives, designed to improve the segment's manufacturing efficiencies, enhance commercial excellence and ensure its long-term global competitiveness. In connection with this global transformational change program, we recorded charges of $28 million related primarily to workforce reduction costs.
	Also during the fourth quarter of 2012, we recorded a loss on early extinguishment of debt of $77 million in connection with the redemption of $400 million of our 2016 Senior Notes.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	3 Months Ended	12 Months Ended
	Mar. 31, 2014	Dec. 31, 2013
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	'	'
Asset Retirement Obligations	'	'
		ASSET RETIREMENT OBLIGATIONS
		We accrue for asset retirement obligations, which consist primarily of landfill capping, closure and post-closure costs and asbestos abatement costs, in the period in which the obligations are incurred. Asset retirement obligations are accrued at estimated fair value. When the liability is initially recorded, we capitalize the cost by increasing the carrying amount of the related long- lived asset. Over time, the liability is accreted to its settlement value and the capitalized cost is depreciated over the useful life of the related asset. Upon settlement of the liability, we will recognize a gain or loss for any difference between the settlement amount and the liability recorded. Asset retirement obligations were $29 million and $28 million at December 31, 2013 and 2012, respectively.
Carrying Value of Long-Lived Assets	'	'
		CARRYING VALUE OF LONG-LIVED ASSETS
		We review long-lived assets and all amortizable intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of these assets may not be recoverable. Recoverability is based upon current and anticipated undiscounted cash flows, and we recognize an impairment when such estimated cash flows are less than the carrying value of the asset. Measurement of the amount of impairment, if any, is based upon the difference between carrying value and fair value. Fair value is generally estimated by discounting estimated future cash flows using a discount rate commensurate with the risks involved. See "Note 11. Restructuring, Impairment and Plant Closing Costs."
Cash and Cash Equivalents	'	'
		CASH AND CASH EQUIVALENTS
		We consider cash in checking accounts and cash in short-term highly liquid investments with remaining maturities of three months or less at the date of purchase, to be cash and cash equivalents. Cash flows from discontinued operations are not presented separately in our consolidated statements of cash flows.
Cost of Goods Sold	'	'
		COST OF GOODS SOLD
		We classify the costs of manufacturing and distributing our products as cost of goods sold. Manufacturing costs include variable costs, primarily raw materials and energy, and fixed expenses directly associated with production. Manufacturing costs also include, among other things, plant site operating costs and overhead (including depreciation), production planning and logistics costs, repair and maintenance costs, plant site purchasing costs, and engineering and technical support costs. Distribution, freight and warehousing costs are also included in cost of goods sold.
Derivatives and Hedging Activities	'	'
		DERIVATIVES AND HEDGING ACTIVITIES
		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. Changes in the fair value of the hedge in the net investment of certain international operations are recorded in other comprehensive income (loss), to the extent effective. The effectiveness of a cash flow hedging relationship is established at the inception of the hedge, and after inception we perform effectiveness assessments at least every three months. A derivative designated as a cash flow hedge is determined to be effective if the change in value of the hedge divided by the change in value of the hedged item is within a range of 80% to 125%. Hedge ineffectiveness in a cash flow hedge occurs only if the cumulative gain or loss on the derivative hedging instrument exceeds the cumulative change in the expected future cash flows on the hedged transaction. For a derivative that does not qualify or has not been designated as a hedge, changes in fair value are recognized in earnings.
Environmental Expenditures	'	'
		ENVIRONMENTAL EXPENDITURES
		Environmental related restoration and remediation costs are recorded as liabilities when site restoration and environmental remediation and clean-up obligations are either known or considered probable and the related costs can be reasonably estimated. Other environmental expenditures that are principally maintenance or preventative in nature are recorded when expended and incurred and are expensed or capitalized as appropriate. See "Note 19. Environmental, Health and Safety Matters."
Foreign Currency Translation	'	'
		FOREIGN CURRENCY TRANSLATION
		The accounts of our operating subsidiaries outside of the U.S., unless they are operating in highly inflationary economic environments, consider the functional currency to be the currency of the economic environment in which they operate. Accordingly, assets and liabilities are translated at rates prevailing at the balance sheet date. Revenues, expenses, gains and losses are translated at a weighted average rate for the period. Cumulative translation adjustments are recorded to equity as a component of accumulated other comprehensive loss.
		If a subsidiary operates in an economic environment that is considered to be highly inflationary (100% cumulative inflation over a three-year period), the U.S. dollar is considered to be the functional currency and gains and losses from remeasurement to the U.S. dollar from the local currency are included in the statement of operations. Where a subsidiary's operations are effectively run, managed, financed and contracted in U.S. dollars, such as certain finance subsidiaries outside of the U.S., the U.S. dollar is considered to be the functional currency.
		Foreign currency transaction gains and losses are recorded in other operating expense (income) in our consolidated statements of operations and were net losses of $11 million, $4 million and $3 million for the years ended December 31, 2013, 2012 and 2011, respectively.
Income Taxes	'	'
		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 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.
		We do not provide for income taxes or benefits on the undistributed earnings of our non-U.S. subsidiaries as earnings are reinvested and, in the opinion of management, will continue to be reinvested indefinitely.
		Accounting for uncertainty in income taxes prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. The application of income tax law is inherently complex. We are required to determine if an income tax position meets the criteria of more-likely-than-not to be realized based on the merits of the position under tax law, in order to recognize an income tax benefit. This requires us to make significant judgments regarding the merits of income tax positions and the application of income tax law. Additionally, if a tax position meets the recognition criteria of more-likely-than-not we are required to make judgments and apply assumptions to measure the amount of the tax benefits to recognize. These judgments are based on the probability of the amount of tax benefits that would be realized if the tax position was challenged by the taxing authorities. Interpretations and guidance surrounding income tax laws and regulations change over time. As a consequence, changes in assumptions and judgments can materially affect amounts recognized in our consolidated financial statements.
Intangible Assets and Goodwill	'	'
		INTANGIBLE ASSETS AND GOODWILL
		Intangible assets are stated at cost (fair value at the time of acquisition) and are amortized using the straight-line method over the estimated useful lives or the life of the related agreement as follows:
		Patents and technology	5 - 30 years
		Trademarks	15 - 30 years
		Licenses and other agreements	5 - 15 years
		Other intangibles	5 - 15 years
		Goodwill represents costs in excess of fair values assigned to the underlying net assets of acquired businesses. Goodwill is not subject to any method of amortization, but is tested for impairment annually (at the beginning of the third quarter) and when events and circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. When the fair value is less than the carrying value of the related reporting unit, we are required to reduce the amount of goodwill through a charge to earnings. Fair value is estimated using the market approach, as well as the income approach based on discounted cash flow projections. Goodwill has been assigned to reporting units for purposes of impairment testing. Goodwill increased by $14 million during the year ended December 31, 2013 due to the finalization of purchase accounting.
Inventories	'	'
		INVENTORIES
		Inventories are stated at the lower of cost or market, with cost determined using LIFO, first-in first-out, and average costs methods for different components of inventory.
Legal Costs	'	'
		LEGAL COSTS
		We expense legal costs, including those legal costs incurred in connection with a loss contingency, as incurred.
Other Noncurrent Assets	'	'
		OTHER NONCURRENT ASSETS
		Other noncurrent assets consist primarily of spare parts, deferred debt issuance costs, the overfunded portion related to defined benefit plans for employees and capitalized turnaround costs. Debt issuance costs are amortized using the interest method over the term of the related debt.
Principles of Consolidation	'	'
	PRINCIPLES OF CONSOLIDATION	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. Intercompany accounts and transactions have been eliminated.	Our consolidated financial statements 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.
Property, Plant and Equipment	'	'
		PROPERTY, PLANT AND EQUIPMENT
		Property, plant and equipment is stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives or lease term as follows:
		Buildings and equipment	5 - 50 years
		Plant and equipment	3 - 30 years
		Furniture, fixtures and leasehold improvements	5 - 20 years
		Interest expense capitalized as part of plant and equipment was $7 million, $4 million and $2 million for the years ended December 31, 2013, 2012 and 2011, respectively.
		Periodic maintenance and repairs applicable to major units of manufacturing facilities (a "turnaround") are accounted for on the deferral basis by capitalizing the costs of the turnaround and amortizing the costs over the estimated period until the next turnaround. Normal maintenance and repairs of plant and equipment are charged to expense as incurred. Renewals, betterments and major repairs that materially extend the useful life of the assets are capitalized, and the assets replaced, if any, are retired.
Revenue Recognition	'	'
		REVENUE RECOGNITION
		We generate substantially all of our revenues through sales in the open market and long-term supply agreements. We recognize revenue when it is realized or realizable and earned. Revenue for product sales is recognized when a sales arrangement exists, risk and title to the product transfer to the customer, collectability is reasonably assured and pricing is fixed or determinable. The transfer of risk and title to the product to the customer usually occurs at the time shipment is made.
		Revenue arrangements that contain multiple deliverables, which relate primarily to licensing of technology, are evaluated to determine whether the arrangements should be divided into separate units of accounting and how the arrangement consideration should be measured and allocated among the separate units of accounting.
Securitization of Accounts Receivable	'	'
		SECURITIZATION OF ACCOUNTS RECEIVABLE
		Under our A/R Programs, we grant an undivided interest in certain of our trade receivables to the U.S. SPE and the EU SPE. This undivided interest serves as security for the issuance of debt. The A/R Programs provide for financing through a conduit program (in both U.S. dollars and euros). The amounts outstanding under our A/R Programs are accounted for as secured borrowings. See "Note 13. Debt—A/R Programs."
Stock-Based Compensation	'	'
		STOCK-BASED COMPENSATION
		We measure the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award. That cost will be recognized over the period during which the employee is required to provide services in exchange for the award. See "Note 21. Stock-Based Compensation Plan."
Subsequent Events	'	'
		SUBSEQUENT EVENTS
		We have evaluated material subsequent events through the date these consolidated financial statements were issued.
Use of Estimates	'	'
	USE OF ESTIMATES	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.

Recently Issued Accounting Pronouncements	'	'
		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 consolidated financial statements.
		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 in the notes to our consolidated financial statements. See "Note 22. Other Comprehensive Income (Loss)."
		In July 2013, the FASB issued ASU No. 2013-10, Derivatives and Hedging (Topic 815): Inclusion of the Fed Funds Effective Swap Rate (or Overnight Index Swap Rate) as a Benchmark Interest Rate for Hedge Accounting Purposes, permitting entities to use the Fed Funds Effective Swap Rate (OIS) as a U.S. benchmark interest rate for hedge accounting purposes under Topic 815, in addition to the U.S. Treasury rate and the London Interbank Offered Rate (LIBOR). The amendments also remove the restriction on using different benchmark rates for similar hedges. The amendments in this ASU were effective prospectively for qualifying new or redesignated hedging relationships entered into on or after July 17, 2013. We adopted the amendments in this ASU effective July 17, 2013, and the initial adoption of the amendments in this ASU did not have a significant impact on our consolidated financial statements.
		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 consolidated financial statements.
		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 consolidated financial statements.
		In July 2013, the FASB issued ASU No. 2013-11, Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists, providing guidance on the presentation of unrecognized tax benefits in the financial statements as either a reduction to a deferred tax asset or as a liability to better reflect the manner in which an entity would settle at the reporting date any additional income taxes that would result from the disallowance of a tax position when net operating loss carryforwards ("NOLs"), similar tax losses or tax credit carryforwards exist. The amendments in this ASU do not require new recurring disclosures. 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 prospectively to all unrecognized tax benefits that exist at the effective date. Retrospective application is permitted. We do not expect the adoption of the amendments in this ASU to have a significant impact on our consolidated financial statements.

														We are party to cross-currency interest rate contracts that are measured at fair value in our consolidated 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 2012, this credit valuation adjustment has 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).

	During 2012, our Polyurethanes segment implemented a restructuring program to reduce annualized fixed costs. In connection with this program, we recorded restructuring expenses of $5 million, $32 million and $1 million in the first, third and fourth quarters of 2012, respectively.
	-2
	During the fourth quarter of 2012, our Advanced Materials segment began implementing a global transformational change program, subject to consultation with relevant employee representatives, designed to improve the segment's manufacturing efficiencies, enhance commercial excellence and ensure its long-term global competitiveness. In connection with this global transformational change program, we recorded charges of $28 million related primarily to workforce reduction costs.
	Also during the fourth quarter of 2012, we recorded a loss on early extinguishment of debt of $77 million in connection with the redemption of $400 million of our 2016 Senior Notes.
	-3
	Basic and diluted income per share are computed independently for each of the quarters presented based on the weighted average number of common shares outstanding during that period. Therefore, the sum of quarterly basic and diluted per share information may not equal annual basic and diluted earnings per share.
