NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

December 31, 2015

UNAUDITED

A. Basis of Presentation

The consolidated financial statements include the accounts of Cabot Corporation (“Cabot” or the “Company”) and its wholly owned subsidiaries and majority-owned and controlled U.S. and non-U.S. subsidiaries. Additionally, Cabot considers consolidation of entities over which control is achieved through means other than voting rights. Intercompany transactions have been eliminated in consolidation.

The unaudited consolidated financial statements have been prepared in accordance with the requirements of Form 10-Q and consequently do not include all disclosures required by Form 10-K. Additional information may be obtained by referring to Cabot’s Annual Report on Form 10-K for the fiscal year ended September 30, 2015 (“2015 10-K”).

The financial information submitted herewith is unaudited and reflects all adjustments which are, in the opinion of management, necessary to provide a fair statement of the results for the interim periods ended December 31, 2015 and 2014. All such adjustments are of a normal recurring nature. The results for interim periods are not necessarily indicative of the results to be expected for the fiscal year.

B. Significant Accounting Policies

Revenue Recognition and Accounts Receivable

Cabot recognizes revenue when persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, the price is fixed or determinable and collectability is reasonably assured. Cabot generally is able to ensure that products meet customer specifications prior to shipment. If the Company is unable to determine that the product has met the specified objective criteria prior to shipment or if title has not transferred because of sales terms, the revenue is considered “unearned” and is deferred until the revenue recognition criteria are met.

Shipping and handling charges related to sales transactions are recorded as sales revenue when billed to customers or included in the sales price. Taxes collected on sales to customers are excluded from revenues.

The following table shows the relative size of the revenue recognized in each of the Company’s reportable segments.

Cabot derives the substantial majority of its revenues from the sale of products in Reinforcement Materials and Performance Chemicals. Revenue from these products is typically recognized when the product is shipped and title and risk of loss have passed to the customer. The Company offers certain of its customers cash discounts and volume rebates as sales incentives. The discounts and volume rebates are recorded as a reduction in sales at the time revenue is recognized and are estimated based on historical experience and contractual obligations. Cabot periodically reviews the assumptions underlying its estimates of discounts and volume rebates and adjusts its revenues accordingly.

Revenue in Purification Solutions is typically recognized when the product is shipped and title and risk of loss have passed to the customer. For major activated carbon injection systems projects, revenue is recognized using the percentage-of-completion method.

8

Revenue in Specialty Fluids arises primarily from the rental of cesium formate. This revenue is recognized throughout the rental period based on the contracted rental ter ms. Customers are also billed and revenue is recognized, typically at the end of the job, for cesium formate product that is not returned. The Company also generates revenues from cesium formate sold outside of a rental process and revenue is recognized up on delivery of the fluid .

Cabot maintains allowances for doubtful accounts based on an assessment of the collectability of specific customer accounts, the aging of accounts receivable and other economic information on both a historical and prospective basis. Customer account balances are charged against the allowance when it is probable the receivable will not be recovered. There were no material changes in the allowance for any of the years presented. There is no material off-balance sheet credit exposure related to customer receivable balances.

Intangible Assets and Goodwill Impairment

The Company records tangible and intangible assets acquired and liabilities assumed in business combinations under the acquisition method of accounting. Amounts paid for an acquisition are allocated to the assets acquired and liabilities assumed based on their fair values at the date of acquisition. Goodwill is comprised of the purchase price of business acquisitions in excess of the fair value assigned to the net tangible and identifiable intangible assets acquired. Goodwill is not amortized, but is reviewed for impairment annually as of May 31, or when events or changes in the business environment indicate that the carrying value of the reporting unit may exceed its fair value. A reporting unit, for the purpose of the impairment test, is at or below the operating segment level, and constitutes a business for which discrete financial information is available and regularly reviewed by segment management. The reporting units with goodwill balances are Reinforcement Materials, Purification Solutions, and Fumed Metal Oxides. The separate businesses included within Performance Chemicals are considered separate reporting units. As such, the goodwill balance relative to Performance Chemicals is recorded in the Fumed Metal Oxides reporting unit.

For the purpose of the goodwill impairment test, the Company first assesses qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If an initial qualitative assessment identifies that it is more likely than not that the carrying value of a reporting unit exceeds its estimated fair value, an additional quantitative evaluation is performed under the two-step impairment test. Alternatively, the Company may elect to proceed directly to the quantitative goodwill impairment test. If based on the quantitative evaluation the fair value of the reporting unit is less than its carrying amount, the Company performs an analysis of the fair value of all assets and liabilities of the reporting unit. If the implied fair value of the reporting unit’s goodwill is determined to be less than its carrying amount, an impairment is recognized for the difference. The fair value of a reporting unit is based on discounted estimated future cash flows. The fair value is also benchmarked against a market approach using the guideline public companies method. The assumptions used to estimate fair value include management’s best estimates of future growth rates, operating cash flows, capital expenditures and discount rates over an estimate of the remaining operating period at the reporting unit level. Should the fair value of any of the Company’s reporting units decline below its carrying amount because of reduced operating performance, market declines, changes in the discount rate, or other conditions, charges for impairment may be necessary. Based on the Company’s most recent annual goodwill impairment test performed as of May 31, 2015, the fair values of the Reinforcement Materials and Fumed Metal Oxides reporting units were substantially in excess of their carrying values.  The fair value of the Purification Solutions reporting unit was less than its carrying amount and an impairment was recorded in the third fiscal quarter of 2015. Due to the impairment recorded as of June 30, 2015, the fair value of the Purification Solutions reporting unit was insignificantly higher than its carrying value as of the last impairment date. No events occurred subsequent to the last impairment evaluation that would suggest that it is more likely than not that the carrying values of any of our reporting units exceeded their fair value.

Nonetheless, the future growth in the Purification Solutions segment is highly dependent on achieving the expected volumes and margins in the activated carbon based mercury removal business. These volumes and margins are highly dependent on demand for mercury removal products and the Company’s successful realization of its anticipated share of volumes in this business. The expected demand for mercury removal products significantly depends on: (1) the implementation and enforcement of environmental laws and regulations, particularly those that would require U.S. based coal-fired electric utilities to reduce the quantity of air pollutants they release, including mercury, to comply with the Mercury and Air Toxics Standards (“MATS”) issued by the U.S. Environmental Protection Agency (“EPA”) and (2) other factors such as the anticipated usage of activated carbon in the coal-fired energy units. The MATS regulation has been subject to legal challenge and, in June 2015, the U.S. Supreme Court held that the EPA unreasonably failed to consider costs in determining whether it is necessary and appropriate to regulate hazardous air pollutants, including mercury, emitted by coal-fired utilities, and remanded the case back to the United States Court of Appeals for the District of Columbia Circuit Court for further proceedings. On December 15, 2015, the D.C. Circuit Court ruled to keep the MATS

9

regulation in place while the EPA works to address the cost analysis required by the U.S. Supreme Court’s decision. EPA has indicated that it will complete this work by April 2016.

The Company uses assumptions and estimates in determining the fair value of assets acquired and liabilities assumed in a business combination. The determination of the fair value of intangible assets requires the use of significant judgment with regard to assumptions used in the valuation model. The Company estimates the fair value of identifiable acquisition-related intangible assets principally based on projections of cash flows that will arise from these assets. The projected cash flows are discounted to determine the fair value of the assets at the dates of acquisition.

Definite-lived intangible assets, which are comprised of trademarks, customer relationships and developed technologies, are amortized over their estimated useful lives and are reviewed for impairment when indication of potential impairment exists, such as a significant reduction in cash flows associated with the assets. The Company recognized an impairment on intangible assets associated with the Purification Solutions business in the third fiscal quarter of 2015 and no events have been subsequently identified that would require an additional impairment evaluation.

Long-lived Assets Impairment

The Company’s long-lived assets primarily include property, plant and equipment, intangible assets, long-term investments and assets held for rent. The carrying values of long-lived assets are reviewed for impairment whenever events or changes in business circumstances indicate that the carrying amount of an asset may not be recoverable.

To test for impairment of assets, the Company generally uses a probability-weighted estimate of the future undiscounted net cash flows of the assets over their remaining lives to determine if the value of the asset is recoverable. Long-lived assets are grouped with other assets and liabilities at the lowest level for which independent identifiable cash flows are determinable.

An asset impairment is recognized when the carrying value of the asset is not recoverable based on the analysis described above, in which case the asset is written down to its fair value. If the asset does not have a readily determinable market value, a discounted cash flow model may be used to determine the fair value of the asset. In circumstances when an asset does not have separate identifiable cash flows, an impairment charge is recorded when the Company no longer intends to use the asset.

Property, Plant and Equipment

Property, plant and equipment are recorded at cost. Depreciation of property, plant and equipment is calculated using the straight-line method over the estimated useful lives. The depreciable lives for buildings, machinery and equipment, and other fixed assets are twenty to twenty-five years, ten to twenty-five years, and three to twenty-five years, respectively. The cost and accumulated depreciation for property, plant and equipment sold, retired, or otherwise disposed of are removed from the Consolidated Balance Sheets and resulting gains or losses are included in earnings in the Consolidated Statements of Operations. Expenditures for repairs and maintenance are charged to expenses as incurred. Expenditures for major renewals and betterments, which significantly extend the useful lives of existing plant and equipment, are capitalized and depreciated.

Income Tax in Interim Periods

The Company records its tax provision or benefit on an interim basis using an estimated annual effective tax rate. This rate is applied to the current period ordinary income or loss to determine the income tax provision or benefit allocated to the interim period. Losses from jurisdictions for which no benefit can be recognized and the income tax effects of unusual or infrequent items are excluded from the estimated annual effective tax rate and are recognized in the impacted interim period.

Valuation allowances are provided against the future tax benefits that arise from the deferred tax assets in jurisdictions for which no benefit can be recognized. The estimated annual effective tax rate may be significantly impacted by nondeductible expenses and the Company’s projected earnings mix by tax jurisdiction. Adjustments to the estimated annual effective income tax rate are recognized in the period when such estimates are revised.

Inventory Valuation

Inventories are stated at the lower of cost or market. The cost of all carbon black inventories in the U.S. is determined using the last-in, first-out (“LIFO”) method. Had the Company used the first-in, first-out (“FIFO”) method instead of the LIFO method for

10

such inventories, the value of those inventories would have been $28 million and $30 million higher as of December 31, 2015 and September 30, 2015, respectively. The cost of Specialty Fluids inventories, which are classified as assets held for rent, is determined using the average cost method. The cost of other U.S. and non-U.S. inventories is determined using the first-in, first-out (“FIFO”) method.

Cabot reviews inventory for both potential obsolescence and potential declines in anticipated selling prices. In this review, the Company makes assumptions about the future demand for and market value of the inventory, and based on these assumptions estimates the amount of any obsolete, unmarketable, slow moving, or overvalued inventory. Cabot writes down the value of these inventories by an amount equal to the difference between the cost of the inventory and its estimated net realizable value.

Pensions and Other Postretirement Benefits

The Company recognizes the funded status of defined benefit pension and other postretirement benefit plans as an asset or liability. This amount is defined as the difference between the fair value of plan assets and the benefit obligation. The Company is required to recognize as a component of other comprehensive income, net of tax, the actuarial gains/losses and prior service costs/credits that arise but were not previously required to be recognized as components of net periodic benefit cost. Other comprehensive income is adjusted as these amounts are later recognized in income as components of net periodic benefit cost.

Accumulated Other Comprehensive (Loss) Income

Accumulated other comprehensive (loss) income, which is included as a component of stockholders’ equity, includes unrealized gains or losses on available-for-sale marketable securities and derivative instruments, currency translation adjustments in foreign subsidiaries, translation adjustments on foreign equity securities and minimum pension liability adjustments.

Recent Accounting Pronouncements

In May 2014, the FASB issued a new standard related to the “Revenue from Contracts with Customers” which amends the existing accounting standards for revenue recognition. The standard requires entities to recognize revenue when they transfer promised goods or services to customers in an amount that reflects the consideration the entity expects to be entitled to in exchange for those goods or services. This standard is applicable for fiscal years beginning after December 15, 2017 and for interim periods within those years and early adoption is permitted for the fiscal years beginning after December 15, 2016. The Company expects to adopt this standard on October 1, 2018. The Company is currently evaluating the impact the adoption of this standard may have on its consolidated financial statements.

In April 2015, the FASB issued a new standard simplifying the presentation of debt issuance costs by requiring debt issuance costs to be presented as a reduction of the corresponding debt liability. This will make the presentation of debt issuance costs consistent with the presentation of debt discounts or premiums. This standard is applicable for fiscal years beginning after December 15, 2015 and for interim periods within those years and early adoption is permitted. The Company expects to adopt this standard on October 1, 2016. The adoption of this standard is not expected to materially impact the Company’s consolidated financial statements.

In November 2015, the FASB issued a new standard that amends the existing accounting standard for Income Taxes and simplifies the presentation of deferred income taxes.  This will require that deferred income tax assets and liabilities be classified as noncurrent on the balance sheet.  This standard is applicable for fiscal years beginning after December 15, 2016 and for interim periods within those years and early adoption is permitted.  The Company is evaluating this standard and the timing of its adoption. The adoption of this standard is not expected to materially impact the Company’s consolidated financial statements.

Settlement of employee benefit plan

Effective October 1, 2014, the Company transferred the defined benefit obligations and pension plan assets in one of its foreign defined benefit plans to a multi-employer plan. As a result of the transfer, a pre-tax charge of $18 million was recorded in the three months ended December 31, 2014 as reflected in Settlement costs in the table above. The pre-tax charge consists of $27 million released from Accumulated other comprehensive (loss) income (“AOCI”) and $2 million of employer contributions at the time of the settlement, partially offset by an $11 million release of the pension liability. The settlement charge has been recorded primarily in Cost of sales in the Consolidated Statements of Operations.

The following table provides information regarding the Company’s intangible assets:

Intangible assets are amortized over their estimated useful lives, which range from fourteen to twenty-five years, with a weighted average amortization period of approximately nineteen years. Amortization expense for the three months ended December 31, 2015 and 2014 was $2 million and $4 million, respectively, and is included in Cost of sales and Selling and

12

administrative expenses in the Consolidated Statements of Operations. Total amortization expense is estimated to be approximately $9 million each year for the next five fiscal years.

E. Stockholders’ Equity

In fiscal 2007, the Board of Directors authorized Cabot to repurchase up to ten million shares of Cabot’s common stock in the open market or in privately negotiated transactions. This authorization did not have a set expiration date. During the first quarter of fiscal 2015, Cabot repurchased 925,700 shares of its common stock under this authorization.

In January 2015, the Board of Directors authorized Cabot to repurchase up to five million shares of its common stock in the open market or in privately negotiated transactions and cancelled the previous authorization. Cabot has repurchased 1,594,300 shares of its common stock under this authorization. As of December 31, 2015, 3,405,700 shares remain available for repurchase under the current authorization. The Company retired the repurchased shares and recorded the excess of the purchase price over par value to additional paid-in capital until such amount was reduced to zero and then charged the remainder against retained earnings.

During the first three months of both fiscal 2016 and 2015, Cabot paid cash dividends of $0.22 per share of common stock for a total of $14 million.

Noncontrolling interest

The following table illustrates the noncontrolling interest activity for the periods presented:

The dividends declared during the three months ended December 31, 2015 were not paid during the period.

13

The amounts reclassified out of AOCI and into the Consolidated Statements of Operations in the three months ended December 31, 2015 and 2014 are as follows:

Guarantee Agreements

Cabot has provided certain indemnities pursuant to which it may be required to make payments to an indemnified party in connection with certain transactions and agreements. In connection with certain acquisitions and divestitures, Cabot has provided routine indemnities with respect to such matters as environmental, tax, insurance, product and employee liabilities. In connection with various other agreements, including service and supply agreements with customers, Cabot has provided indemnities for certain contingencies and routine warranties. Cabot is unable to estimate the maximum potential liability for these types of indemnities as a maximum obligation is not explicitly stated in most cases and the amounts, if any, are dependent upon the outcome of future contingent events, the nature and likelihood of which cannot be reasonably estimated. The duration of the indemnities vary, and in many cases are indefinite. Cabot has not recorded any liability for these indemnities in the consolidated financial statements, except as otherwise disclosed.

Contingencies

Cabot is a defendant, or potentially responsible party, in various lawsuits and environmental proceedings wherein substantial amounts are claimed or at issue.

14

Environmental Matters

As of December 31, 2015 and September 30, 2015, Cabot had $15 million and $16 million, respectively, reserved for environmental matters. These environmental matters mainly relate to closed sites. These reserves represent Cabot’s best estimates of the probable costs to be incurred at those sites where costs are reasonably estimable based on the Company’s analysis of the extent of clean up required, alternative clean-up methods available, abilities of other responsible parties to contribute and its interpretation of laws and regulations applicable to each site. Cash payments related to these environmental matters were less than $1 million in the first three months of fiscal 2016 and 2015, respectively. Cabot reviews the adequacy of the reserves as circumstances change at individual sites and adjusts the reserves as appropriate. Almost all of Cabot’s environmental issues relate to sites that are mature and have been investigated and studied and, in many cases, are subject to agreed upon remediation plans. However, depending on the results of future testing, changes in risk assessment practices, remediation techniques and regulatory requirements, newly discovered conditions, and other factors, it is reasonably possible that the Company could incur additional costs in excess of environmental reserves currently recorded. Management estimates, based on the latest available information, that any such future environmental remediation costs that are reasonably possible to be in excess of amounts already recorded would be immaterial to the Company’s consolidated financial statements.

Other Matters

Respirator Liabilities

Cabot has exposure in connection with a safety respiratory products business that a subsidiary acquired from American Optical Corporation (“AO”) in an April 1990 asset purchase transaction. The subsidiary manufactured respirators under the AO brand and disposed of that business in July 1995. In connection with its acquisition of the business, the subsidiary agreed, in certain circumstances, to assume a portion of AO’s liabilities, including costs of legal fees together with amounts paid in settlements and judgments, allocable to AO respiratory products used prior to the 1990 purchase by the Cabot subsidiary. In exchange for the subsidiary’s assumption of certain of AO’s respirator liabilities, AO agreed to provide to the subsidiary the benefits of: (i) AO’s insurance coverage for the period prior to the 1990 acquisition and (ii) a former owner’s indemnity of AO holding it harmless from any liability allocable to AO respiratory products used prior to May 1982. As more fully described in the 2015 10-K, the respirator liabilities generally involve claims for personal injury, including asbestosis, silicosis and coal worker’s pneumoconiosis, allegedly resulting from the use of respirators that are alleged to have been negligently designed and/or labeled. Neither Cabot, nor its past or present subsidiaries, at any time manufactured asbestos or asbestos-containing products. At no time did this respiratory product line represent a significant portion of the respirator market.

As of December 31, 2015 and September 30, 2015, there were approximately 37,000 and 38,000 claimants, respectively, in pending cases asserting claims against AO in connection with respiratory products. Cabot has a reserve to cover its expected share of liability for existing and future respirator liability claims. At December 31, 2015 and September 30, 2015, the reserve was $10 million and $11 million, respectively. Cash payments related to this liability were $1 million in the first three months of both fiscal 2016 and 2015.

Other

The Company has various other lawsuits, claims and contingent liabilities arising in the ordinary course of its business and with respect to the Company’s divested businesses. In the opinion of the Company, although final disposition of some or all of these other suits and claims may impact the Company’s consolidated financial statements in a particular period, they are not expected, in the aggregate, to have a material adverse effect on the Company’s consolidated financial statements.

15

During the first quarter of fiscal 2016, the Company recorded a tax benefit of $5 million, resulting in an effective tax rate of 7 4 %. This amount included net discrete tax benefits of $6 million , primarily comprised of the net tax benefit from certain foreign exchange gains and losses, the renewal of the U.S. Research and Experimentati on credit and releases of reserves for uncertain tax positions . During the first quarter of fiscal 2015, the Company recorded a tax provision of $3 million, resulting in an effective tax rate of 5%. This amount included net discrete tax benefits of $13 mil lion , primarily comprised of the tax benefit from the change in accounting for uncertain tax positions, the renewal of the U.S. Research and Experimentation credit, and releases of reserves for uncertain tax positions .

Uncertainties

Cabot files U.S. federal and state and non-U.S. income tax returns in jurisdictions with varying statutes of limitations. The 2012 through 2015 tax years remain subject to examination by the United States Internal Revenue Service (“IRS”) and various tax years from 2005 through 2015 remain subject to examination by the respective state tax authorities. In significant non-U.S. jurisdictions, various tax years from 2004 through 2015 remain subject to examination by their respective tax authorities. Cabot’s significant non-U.S. jurisdictions include China, France, Germany, Italy, Japan, and the Netherlands.

Certain Cabot subsidiaries are under audit in jurisdictions outside of the U.S. In addition, certain statutes of limitations are scheduled to expire in the near future. It is reasonably possible that a change in the unrecognized tax benefits may also occur within the next twelve months related to the settlement of one or more of these audits, however, an estimated range of the impact on the unrecognized tax benefits cannot be quantified at this time.

During the three months ended December 31, 2015, Cabot released uncertain tax positions of $2 million due to the expirations of statutes of limitations in various jurisdictions.

Undistributed earnings are the earnings which remain after dividends declared during the period are assumed to be distributed to the common and participating shareholders. Undistributed earnings are allocated to common and participating shareholders on the same basis as dividend distributions. The calculation of undistributed earnings is as follows:

Details of all restructuring activities and the related reserves during the three months ended December 31 , 2015 are as follows:

2016 Plan

On October 20, 2015, in response to challenging macroeconomic conditions, the Company announced its intention to restructure its operations subject to local consultation requirements and processes in certain locations. Cabot’s plan has resulted in a reduction of approximately 300 positions across the Company’s global locations. These actions are intended to result in a more competitive cost structure.

The Company has recorded pre-tax charges of approximately $24 million in the first three months of fiscal 2016, and expects to record an additional $4 million through the rest of fiscal 2016 related to these actions.   The charges recorded and anticipated are comprised of severance, employee benefits and other transition costs.

Cumulative net cash outlays related to these actions are expected to be approximately $28 million, comprised of severance, employee benefits and other transition costs.  Through December 31, 2015, the Company has made $11 million in cash payments related to this plan and expects to make $15 million in cash payments through the remainder of fiscal 2016 and $2 million thereafter.

As of December 31, 2015, Cabot has $14 million of accrued severance costs in the Consolidated Balance Sheet related to this plan.

Additionally, on November 11, 2015, Cabot announced that it had committed to closing its carbon black manufacturing facility in Merak, Indonesia. The decision to close this plant and to consolidate production in Asia using the Company’s Cilegon, Indonesia and other Asian and global carbon black production sites to meet regional demand was driven by the financial performance at the Merak facility in the past several years. Manufacturing operations ceased at the end of January 2016 and approximately 50 employees were affected.

The Company has recorded pre-tax charges of approximately $24 million in the first three months of fiscal 2016 related to this closure, comprised of $22 million of asset impairments and accelerated depreciation and $2 million of severance and employee benefits. The asset impairment charges reflect the write-down of the long-lived assets group that is no longer in use to its fair value.

Future anticipated site closure costs for the Merak facility, anticipated to be recorded through the remainder of fiscal 2016, are $6 million for site remediation and other miscellaneous costs.

Net cash outlays related to this closure are expected to be approximately $8 million, substantially all of which is expected to be paid through the remainder of fiscal 2016.

As of December 31, 2015, Cabot has $2 million of accrued severance costs in the Consolidated Balance Sheet related to the Merak facility closure.

19

Details of the 2016 restructuring activities, including the Merak facility closure, during the three months ended December 31, 2015 are as follows:

Business Service Center Transition

I n January 2014, the Company announced its intention to open a new Europe, Middle East and Africa (“EMEA”) business service center in Riga, Latvia, and to close its Leuven, Belgium site, subject to the Belgian information and consultation process, which was successfully completed in June 2014. These actions were developed following an extensive evaluation of the Company’s business service capabilities in the EMEA region and a determination that the future EMEA business service center will enable the Company to provide the highest quality of service at the most competitive cost.

The actions related to the transition of the business service center have been completed and have resulted in total charges of approximately $24 million, comprised of $16 million of severance charges and $8 million of other transition costs including training costs and redundant salaries. There were no charges related to this plan recorded in the first fiscal quarter of 2016 and $4 million was recorded related to this plan in the first fiscal quarter of 2015.  

Through December 31, 2015, the Company has made $20 million in cash payments related to this plan, comprised of $13 million of severance payments and $7 million of other transition related costs, and expects to make cash payments of approximately $1 million, comprised mainly of severance, in the remainder of fiscal 2016.  The difference between the initial accrual and subsequent cash payments was due to changes in foreign exchange rates.

As of December 31, 2015, Cabot has $1 million of accrued restructuring costs in the Consolidated Balance Sheet related to this closure, which is mainly comprised of accrued severance charges.

Closure of Port Dickson, Malaysia Manufacturing Facility

On April 26, 2013, the Company announced that the Board of its carbon black joint venture, Cabot Malaysia Sdn. Bhd. (“CMSB”), decided to cease production at its Port Dickson, Malaysia facility. The facility ceased production in June 2013. The Company holds a 50.1 percent equity share in CMSB. The decision, which affected approximately 90 carbon black employees, was driven by the facility’s manufacturing inefficiencies and raw materials costs.

Through December 31, 2015, the Company recorded cumulative net pre-tax restructuring charges related to this plan of $19 million, comprised mainly of accelerated depreciation and asset write-offs of $16 million, severance charges of $2 million, site demolition, clearing and environmental remediation charges of $2 million, and other closure related charges of $1 million, partially offset by the gain from the sale of land of $2 million in fiscal 2016. CMSB’s net income or loss is attributable to Cabot Corporation and to the noncontrolling interest in the joint venture.

The Company has recorded a net pre-tax gain of $1 million, and a net pre-tax charge of less than $1 million in the three  months ended December 31, 2015 and 2014, respectively. The portion of the charges that are allocable to the noncontrolling interest in CMSB (49.9%) are recorded within Net income attributable to noncontrolling interests, net of tax, in the Consolidated Statements of Operations. The majority of actions related to closure of the plant were completed in fiscal 2014.

20

Cumulative net cash received related to this plan is $3 million, comprised of $7 million received from the sale of land, partially offset by approximately $2 million for severance, $1 million for site demolition, clea ring and environmental remediation, and $1 million for other closure related charges.

CMSB expects to make cash payments of less than $1 million during the remainder of fiscal 2016 mainly for site demolition, clearing and environmental remediation costs.

As of December 31, 2015, Cabot has less than $1 million of accrued restructuring costs in the Consolidated Balance Sheets related to this closure, which is mainly for accrued environmental and other charges.

Other Activities

The Company has recorded other pre-tax restructuring charges of approximately $1 million during each of the first quarters of fiscal 2016 and 2015.  Fiscal 2016 charges are comprised mainly of accelerated depreciation and severance costs whereas fiscal 2015 charges are comprised of severance costs. Future charges related to these actions are anticipated to be less than $1 million in the remainder of fiscal 2016 and thereafter.

As of December 31, 2015, Cabot has $3 million of accrued severance and other closure related costs in the Consolidated Balance Sheets related to these activities which is expected to be paid through early fiscal 2017.

Previous Actions and Sites Pending Sale

Beginning in fiscal 2009, the Company entered into several different restructuring plans which have been substantially completed, pending the sale of former manufacturing sites in Thane, India and Hong Kong. The Company has incurred total cumulative pre-tax charges of approximately $165 million related to these plans through December 31, 2015, comprised of $67 million for severance charges, $66 million for accelerated depreciation and asset impairments, $10 million for environmental, demolition and site clearing costs, and $23 million of other closure related charges, partially offset by gains on asset sales of $1 million. The Company anticipates that it will record a gain on the sale of land rights in Hong Kong of $8 million during fiscal 2016.

Pre-tax restructuring expenses related to these plans were less than $1 million and $2 million during the first three months of fiscal 2016 and 2015, respectively.   Since fiscal 2009, Cabot has made net cash payments of $87 million related to these plans and expects to receive approximately $9 million from the sale of land rights in Hong Kong during fiscal 2016, partially offset by payments of approximately $2 million for environmental and other closure related costs.

As of December 31, 2015, Cabot has $2 million of accrued environmental  and other closure related costs in the Consolidated Balance Sheets related to these activities.

There were no transfers of financial assets or liabilities measured at fair value between Level 1 and Level 2, or transfers into or out of Level 3, during the first three months of either fiscal 2016 or 2015.

21

At December 31, 2015 and September 30, 2015, the fair value of G uaranteed investment contr acts, included in Other assets o n the Consolidated Balance Sheets, was $ 11 million and $1 2 million, respectively . Guaranteed investment contracts were classified as Level 2 instruments within the fair value hierarchy as the fair value determination was based on other observable inputs.

At December 31, 2015 and September 30, 2015, the fair values of cash and cash equivalents, accounts and notes receivable, accounts payable and accrued liabilities, and notes payable and variable rate debt approximated their carrying values due to the short-term nature of these instruments. The carrying value and fair value of the long-term fixed rate debt were $0.96 billion and $1.01 billion, respectively, as of December 31, 2015 and $0.96 billion and $1.02 billion, respectively, as of September 30, 2015. The fair values of Cabot’s fixed rate long-term debt and capital lease obligations are estimated based on comparable quoted market prices at the respective period ends. The carrying amounts of Cabot’s floating rate long-term debt and capital lease obligations approximate their fair values. All such measurements are based on observable inputs and are classified as Level 2 within the fair value hierarchy. The valuation technique used is the discounted cash flow model.

L. Derivatives

Interest Rate Risk Management

Cabot’s objective is to maintain a certain fixed-to-variable interest rate mix on the Company’s debt obligations. Cabot may enter into interest rate swaps as a hedge of the underlying debt instruments to effectively change the characteristics of the interest rate without changing the debt instrument. As of both December 31, 2015 and September 30, 2015, there were no derivatives held to manage interest rate risk.

Foreign Currency Risk Management

Cabot’s international operations are subject to certain risks, including currency exchange rate fluctuations and government actions. Cabot endeavors to match the currency in which its debt is issued to the currency of the Company’s major, stable cash receipts. In some situations Cabot has issued debt denominated in U.S. dollars and then entered into cross currency swaps that exchange the dollar principal and interest payments into a currency where the Company expects long-term, stable cash receipts.

Additionally, the Company has foreign currency exposure arising from its net investments in foreign operations. Cabot, from time to time, enters into cross-currency swaps to mitigate the impact of currency rate changes on the Company’s net investments.

The Company also has foreign currency exposure arising from the denomination of monetary assets and liabilities in foreign currencies other than the functional currency of a given subsidiary as well as the risk that currency fluctuations could affect the dollar value of future cash flows generated in foreign currencies. Accordingly, Cabot uses short-term forward contracts to minimize the exposure to foreign currency risk. In certain situations where the Company has forecasted purchases under a long-term commitment or forecasted sales denominated in a foreign currency, Cabot may enter into appropriate financial instruments in accordance with the Company’s risk management policy to hedge future cash flow exposures.

The following table provides details of the derivatives held as of December 31, 2015 and September 30, 2015 to manage foreign currency risk.

Accounting for Derivative Instruments and Hedging Activities

The Company determines the fair value of financial instruments using quoted market prices whenever available. When quoted market prices are not available for various types of financial instruments (such as forwards, options and swaps), the Company uses standard models with market-based inputs, which take into account the present value of estimated future cash flows and the ability of the financial counterparty to perform. For interest rate and cross-currency swaps, the significant inputs to these models are

interest rate curves for discounting future cash flows. For forward foreign currency contracts, the significant inputs are interest rate curves for discounting future cash flows, and exchange rate curves of the foreign currency for translating future cash flows.

Fair Value Hedge

For derivative instruments that are designated and qualify as fair value hedges, the gain or loss on the derivative as well as the offsetting gain or loss on the hedged item attributable to the hedged risk are recognized in current period earnings.

Cash Flow Hedge

For derivative instruments that are designated and qualify as cash flow hedges, the effective portion of the gain or loss on the derivative is recorded in Accumulated other comprehensive (loss) income and reclassified to earnings in the same period or periods during which the hedged transaction affects earnings. Gains and losses on the derivative representing either hedge ineffectiveness or hedge components excluded from the assessment of effectiveness are recognized in current period earnings.

Other Derivative Instruments

From time to time, the Company may enter into certain derivative instruments that may not be designated as hedges for accounting purposes, which include cross currency swaps, foreign currency forward contracts and commodity derivatives. For cross currency swaps and foreign currency forward contracts not designated as hedges, the Company uses standard models with market-based inputs. The significant inputs to these models are interest rate curves for discounting future cash flows, and exchange rate curves of the foreign currency for translating future cash flows. In determining the fair value of the commodity derivatives, the significant inputs to valuation models are quoted market prices of similar instruments in active markets. Although these derivatives do not qualify for hedge accounting, Cabot believes that such instruments are closely correlated with the underlying exposure, thus managing the associated risk. The gains or losses from changes in the fair value of derivative instruments that are not accounted for as hedges are recognized in current period earnings.

As of both December 31, 2015 and September 30, 2015, the fair value of derivative instruments were immaterial and were presented in Prepaid expenses and other current assets and Accounts payable and accrued liabilities on the Consolidated Balance Sheets.

The net after-tax amounts to be reclassified from AOCI to earnings within the next 12 months are expected to be immaterial.

M. Venezuela

Cabot owns 49% of an operating carbon black affiliate in Venezuela, which is accounted for as an equity affiliate, through wholly-owned subsidiaries that carry the investment and receive its dividends. As of December 31, 2015, these subsidiaries carried the operating affiliate investment of $13 million and held 17 million bolivars (less than $1 million) in cash.

During each of the three month periods ended December 31, 2015 and 2014, the Company received dividends in the amounts of $2 million which were paid in U.S. dollars.

A significant portion of the Company’s operating affiliate’s sales are exports denominated in U.S. dollars. The Venezuelan government mandates that a certain percentage of the dollars collected from these sales be converted into bolivars. The operating affiliate and the Company’s wholly-owned subsidiaries used an exchange rate that was available to Cabot when converting these dollars into bolivars to remeasure their bolivar denominated monetary accounts. The exchange rate made available to us on December 31, 2015 was 52 bolivars to the U.S. dollar.

The operating entity has generally been profitable. The Company continues to closely monitor developments in Venezuela and their potential impact on the recoverability of its equity affiliate investment.

Any future change in the exchange rate made available to the Company or opening of additional parallel markets could cause the Company to change the exchange rate it uses and result in gains or losses on the bolivar denominated assets held by its operating affiliate and wholly-owned subsidiaries.

N . Financial Information by Segment

The Company identifies a business as an operating segment if: i) it engages in business activities from which it may earn revenues and incur expenses; ii) its operating results are regularly reviewed by the Chief Operating Decision Maker (“CODM”) to make decisions about resources to be allocated to the segment and assess its performance; and iii) it has available discrete financial information. The Company has determined that all of its businesses are operating segments. The CODM reviews financial information at the operating segment level to allocate resources and to assess the operating results and financial performance for each operating segment. Operating segments are aggregated into a reportable segment if the operating segments are determined to have similar economic characteristics and if the operating segments are similar in the following areas: i) nature of products and services; ii) nature of production processes; iii) type or class of customer for their products and services; iv) methods used to distribute the products or provide services; and v) if applicable, the nature of the regulatory environment.

The Company has four reportable segments: Reinforcement Materials, Performance Chemicals, Purification Solutions and Specialty Fluids.

The Reinforcement Materials segment represents the rubber blacks and elastomer composites product lines.

Performance Chemicals is comprised of two businesses: (i) our Specialty Carbons and Formulations business, which manufactures and sells specialty grades of carbon black, specialty compounds and inkjet colorants, and (ii) our Metal Oxides business, which manufactures and sells fumed silica, fumed alumina and dispersions thereof and aerogel. The net sales from each of these businesses for the three months ended December 31, 2015 and 2014 are as follows:

The Purification Solutions segment represents the Company’s activated carbon business and the Specialty Fluids segment includes cesium formate oil and gas drilling fluids and high-purity fine cesium chemicals product lines.

Reportable segment operating profit (loss) before interest and taxes (“Segment EBIT”) is presented for each reportable segment in the financial information by reportable segment table below on the line entitled Income (loss) from continuing operations before taxes. Segment EBIT excludes certain items, meaning items management does not consider representative of segment results. In addition, Segment EBIT includes Equity in earnings (loss) of affiliated companies, net of tax, the full operating results of a contractual joint venture in Purification Solutions, royalties, Net income attributable to noncontrolling interests, net of tax, and discounting charges for certain Notes receivable, but excludes Interest expense, foreign currency transaction gains and losses, interest income, dividend income, unearned revenue, the effects of LIFO accounting for inventory, general unallocated expense and unallocated corporate costs.
