2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

ASSET RETIREMENT OBLIGATIONS

ÌýÌýÌýÌýÌýÌýÌýÌýWe 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 estimated 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 $26Ìýmillion and $29Ìýmillion at DecemberÌý31, 2014 and 2013, respectively.

CARRYING VALUE OF LONG-LIVED ASSETS

ÌýÌýÌýÌýÌýÌýÌýÌýWe 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 "NoteÌý11. Restructuring, Impairment and Plant Closing Costs."

CASH AND CASH EQUIVALENTS

ÌýÌýÌýÌýÌýÌýÌýÌýWe 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

ÌýÌýÌýÌýÌýÌýÌýÌýWe 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

ÌýÌýÌýÌýÌýÌýÌýÌýAll 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

ÌýÌýÌýÌýÌýÌýÌýÌýEnvironmental 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 "NoteÌý19. Environmental, Health and Safety Matters."

FOREIGN CURRENCY TRANSLATION

ÌýÌýÌýÌýÌýÌýÌýÌýThe 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.

ÌýÌýÌýÌýÌýÌýÌýÌýIf 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.

ÌýÌýÌýÌýÌýÌýÌýÌýForeign currency transaction gains and losses are recorded in other operating (income) expense in our consolidated statements of operations and were net losses of $15Ìýmillion, $11Ìýmillion and $4Ìýmillion for the years ended DecemberÌý31, 2014, 2013 and 2012, respectively.

INCOME TAXES

ÌýÌýÌýÌýÌýÌýÌýÌýWe 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.

ÌýÌýÌýÌýÌýÌýÌýÌýWe do not provide for income taxes or benefits on the undistributed earnings of our non-U.S. subsidiaries that are reinvested and, in the opinion of management, will continue to be reinvested indefinitely.

ÌýÌýÌýÌýÌýÌýÌýÌýAccounting 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

ÌýÌýÌýÌýÌýÌýÌýÌýIntangible 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:

ÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌý

Ìý

ÌýÌýÌýÌýÌýÌýÌýÌýGoodwill 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. The net change to goodwill in response to changes in foreign currency exchange rates during 2014 was $9Ìýmillion.

INVENTORIES

ÌýÌýÌýÌýÌýÌýÌýÌýInventories 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

ÌýÌýÌýÌýÌýÌýÌýÌýWe expense legal costs, including those legal costs incurred in connection with a loss contingency, as incurred.

NET INCOME PER SHARE ATTRIBUTABLE TO HUNTSMAN CORPORATION

ÌýÌýÌýÌýÌýÌýÌýÌýBasic income per share excludes dilution and is computed by dividing net income attributable to ÀÖÌìÌÃfun88(ÖйúÇø)¹Ù·½ÍøÕ¾ Corporation common stockholders by the weighted average number of shares outstanding during the period. Diluted income per share reflects all potential dilutive common shares outstanding during the period and is computed by dividing net income available to ÀÖÌìÌÃfun88(ÖйúÇø)¹Ù·½ÍøÕ¾ Corporation common stockholders by the weighted average number of shares outstanding during the period increased by the number of additional shares that would have been outstanding as dilutive securities.

ÌýÌýÌýÌýÌýÌýÌýÌýBasic and diluted income per share is determined using the following information (in millions):

ÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌý

ÌýÌýÌýÌýÌýÌýÌýÌýAdditional stock-based awards of 1.0Ìýmillion, 7.3Ìýmillion and 7.8Ìýmillion weighted average equivalent shares of stock were outstanding during the years ended DecemberÌý31, 2014, 2013 and 2012, respectively. However, these stock-based awards were not included in the computation of diluted earnings per share for the respective periods mentioned because the effect would be anti-dilutive.

OTHER NONCURRENT ASSETS

ÌýÌýÌýÌýÌýÌýÌýÌýOther 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

ÌýÌýÌýÌýÌýÌýÌýÌýOur 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.

PROPERTY, PLANT AND EQUIPMENT

ÌýÌýÌýÌýÌýÌýÌýÌýProperty, 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:

ÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌý

ÌýÌýÌýÌýÌýÌýÌýÌýInterest expense capitalized as part of plant and equipment was $16Ìýmillion, $7Ìýmillion and $4Ìýmillion for the years ended DecemberÌý31, 2014, 2013 and 2012, respectively.

ÌýÌýÌýÌýÌýÌýÌýÌýPeriodic 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

ÌýÌýÌýÌýÌýÌýÌýÌýWe 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.

ÌýÌýÌýÌýÌýÌýÌýÌýRevenue 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

ÌýÌýÌýÌýÌýÌýÌýÌýUnder 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 in both U.S. dollars and euros. The amounts outstanding under our A/RÌýPrograms are accounted for as secured borrowings. See "NoteÌý13. Debt—Direct and Subsidiary Debt—A/R Programs."

STOCK-BASED COMPENSATION

ÌýÌýÌýÌýÌýÌýÌýÌýWe 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 "NoteÌý21. Stock-Based Compensation Plan."

SUBSEQUENT EVENTS

ÌýÌýÌýÌýÌýÌýÌýÌýWe have evaluated material subsequent events through the date these consolidated financial statements were issued.

USE OF ESTIMATES

ÌýÌýÌýÌýÌýÌýÌýÌýThe 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 2014

ÌýÌýÌýÌýÌýÌýÌýÌýIn February 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No.Ìý2013-04, 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 DecemberÌý15, 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 JanuaryÌý1, 2014, and the initial adoption of the amendments in this ASU did not have any impact on our consolidated financial statements.

ÌýÌýÌýÌýÌýÌýÌýÌýIn March 2013, the FASB issued ASU No.Ìý2013-05, 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 JanuaryÌý1, 2014, and the initial adoption of the amendments in this ASU did not have any impact on our consolidated financial statements.

ÌýÌýÌýÌýÌýÌýÌýÌýIn July 2013, the FASB issued ASU No.Ìý2013-11, 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 DecemberÌý15, 2013. We adopted the amendments in this ASU effective JanuaryÌý1, 2014, and the initial adoption of the amendments in this ASU did not have any impact on our consolidated financial statements.

ÌýÌýÌýÌýÌýÌýÌýÌýIn November 2014, the FASB issued ASU No.Ìý2014-17, Business Combinations (Topic 805): Pushdown Accounting, providing guidance on whether and at what threshold an acquired entity that is a business or nonprofit activity can apply pushdown accounting in its separate financial statements. The amendments in this ASU provide an acquired entity with an option to apply pushdown accounting in its separate financial statements upon occurrence of an event in which an acquirer obtains control of the acquired entity. An acquired entity may elect the option to apply pushdown accounting in the reporting period in which the change-in-control event occurs or otherwise in a subsequent reporting period to the acquired entity's most recent change-in-control event. The amendments in this ASU were effective on NovemberÌý18, 2014. After the effective date, an acquired entity can make an election to apply the guidance to future change-in-control events or to its most recent change-in-control event. We adopted the amendments in this ASU effective NovemberÌý18, 2014, and the initial adoption of the amendments in this ASU did not have any impact on our consolidated financial statements.

Accounting Pronouncements Pending Adoption in Future Periods

ÌýÌýÌýÌýÌýÌýÌýÌýIn April 2014, the FASB issued ASU No.Ìý2014-08, 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 DecemberÌý15, 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 DecemberÌý15, 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 consolidated financial statements.

ÌýÌýÌýÌýÌýÌýÌýÌýIn May 2014, the FASB issued ASU No.Ìý2014-09, Revenue from Contracts with Customers (TopicÌý606), outlining a single comprehensive model for entities to use in accounting for revenues arising from contracts with customers and supersedes most current revenue recognition guidance. The amendments in this ASU are effective for annual reporting periods beginning after DecemberÌý15, 2016, including interim periods within that reporting period. The amendments in this ASU should be applied retrospectively, and early application is not permitted. We are currently evaluating the impact of the adoption of the amendments in this ASU on our consolidated financial statements.

ÌýÌýÌýÌýÌýÌýÌýÌýIn August 2014, the FASB issued ASU No.Ìý2014-15, Presentation of Financial Statements—Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern, providing guidance about management's responsibility to evaluate whether there is substantial doubt about an entity's ability to continue as a going concern and to provide related footnote disclosures. The amendments in this ASU are effective for the annual period ending after DecemberÌý15, 2016, and for annual periods and interim periods thereafter. Early adoption is permitted. We do not expect the adoption of the amendments in this ASU to have a significant impact on our consolidated financial statements.

ÌýÌýÌýÌýÌýÌýÌýÌýIn January 2015, the FASB issued ASU No.Ìý2015-01, Income Statement—Extraordinary and Unusual Items (Subtopic 225-20): Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items, eliminating from USÌýGAAP the concept of extraordinary items. Reporting entities will no longer have to assess whether a particular event or transaction event is extraordinary. The amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after DecemberÌý15, 2015. A reporting entity may apply the amendments prospectively or may also apply them retrospectively to all prior periods presented in the financial statements. Early adoption is permitted provided that the guidance is applied from the beginning of the 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.
