NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

In the following Notes to Consolidated Financial Statements, “USG,” “we,” “our” and “us” refer to USG Corporation, a Delaware corporation, and its subsidiaries included in the consolidated financial statements, except as otherwise indicated or as the context otherwise requires.


1.	Organization, Consolidation and Presentation of Financial Statements

PREPARATION OF FINANCIAL STATEMENTS

We prepared the accompanying unaudited consolidated financial statements of USG Corporation in accordance with applicable United States Securities and Exchange Commission, or SEC, guidelines pertaining to interim financial information. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America, or U.S. GAAP, requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses. Actual results could differ materially from those estimates. In the opinion of our management, the financial statements reflect all adjustments, which are of a normal recurring nature, necessary for a fair presentation of our financial results for the interim periods. The results of operations for the three and nine months ended September 30, 2015 are not necessarily indicative of the results of operations to be expected for the entire year.

Our investments with Boral Limited in the 50/50 joint ventures, USG Boral Building Products or UBBP, commenced on February 27, 2014, and as a result, seven months of results of UBBP were recorded in our accompanying consolidated statement of operations for the nine months ended September 30, 2014. See Note 2 for further description of our investment in UBBP.

Our segments are structured around our key products and business units: Gypsum, Ceilings, Distribution and UBBP.

Our Gypsum reportable segment is an aggregation of the operating segments of the gypsum businesses in the United States, Canada, Mexico, and Latin America, our mining operation in Little Narrows, Nova Scotia, Canada, and our shipping company, which we have exited. Gypsum manufactures products throughout the United States, Canada, and Mexico. These products include USG Sheetrock^® brand gypsum wallboard and related products including Sheetrock^®brand joint compound, Durock^® brand cement board, Levelrock^® brand gypsum underlayment, Fiberock^® brand gypsum fiber panels, and Securock^®brand glass mat sheathing used for building exteriors and gypsum fiber and glass mat panels used as roof cover board.

Our Ceilings reportable segment is an aggregation of the operating segments of the ceilings businesses in the United States, Canada, Mexico, Latin America and, through February 27, 2014, the businesses in the Asia-Pacific region. Ceilings manufactures ceiling tile in the United States and ceiling grid in the United States, Canada and, through February 27, 2014, the Asia-Pacific region.

Distribution delivers gypsum wallboard, drywall metal, ceilings products, joint compound and other building products throughout the United States.

UBBP manufactures, distributes and sells certain building products, mines raw gypsum and sells natural and synthetic gypsum throughout Asia, Australasia and the Middle East.

These financial statements and notes are to be read in conjunction with the financial statements and notes included in USG’s Annual Report on Form 10-K for the fiscal year ended December 31, 2014, which we filed with the SEC on February 12, 2015.

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

In July 2015, the Financial Accounting Standards Board, or FASB, issued Accounting Standard Update, or ASU, 2015-11, "Simplifying the Measurement of Inventory", which changes the measurement principle for inventory from the lower of cost or market to the lower of cost or net realizable value for entities that measure inventory using the first-in, first-out (FIFO) or average cost method. The ASU defines net realizable value as estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The standard will be effective for us in the first quarter of 2017, with early adoption permitted. We are evaluating the effect of adopting this standard, but we do not expect the adoption of ASU 2015-11 will have a significant impact to our consolidated financial statements or disclosures.

In May 2015, the FASB issued ASU 2015-07, "Disclosures for Investments in Certain Entities That Calculate Net Asset Value per Share (or Its Equivalent)," which updates the disclosure requirements for investments that are measured at net asset value using the practical expedient. These investments are to be removed from the fair value hierarchy and shown as a

Table of Contents

reconciling item. The standard will be effective for us in the first quarter of 2016, with early adoption permitted. We do not expect that the adoption of ASU 2015-07 will have a significant impact to our consolidated financial statements or disclosures.

In April 2015, the FASB issued ASU 2015-03, "Simplifying the Presentation of Debt Issuance Costs", which requires costs related to a recognized debt liability to be presented on the balance sheet as a direct deduction from the debt liability rather than as an asset. In August 2015, the FASB issued ASU 2015-15, "Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements", which clarifies that the SEC staff would not object to an entity deferring and presenting debt issuance costs as an asset, regardless of whether there are any outstanding borrowings on the line-of-credit. The standards will be effective for us in the first quarter of 2016, with early adoption permitted. We plan to early adopt the standards as of December 31, 2015. Upon adoption, we would reclassify our deferred debt issuance costs associated with our long-term debt other than our line-of-credit from other assets to long term debt. If adopted as of September 30, 2015, we would have recorded a reduction in both other assets and long-term debt of $14 million and would have provided additional disclosure.

In August 2014, the FASB issued ASU 2014-15, "Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern," which requires management to assess, at each annual and interim reporting period, the entity's ability to continue as a going concern within one year of date of the financial statements are issued and provide related disclosures. The new standard will be effective for us for the year ended December 31, 2016, with early adoption permitted. We do not expect that the adoption of ASU 2014-15 will have a significant impact to our consolidated financial statements or disclosures.

In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers,” which supersedes the revenue recognition requirements in “Revenue Recognition (Topic 605),” and requires entities to recognize revenue in a way that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. There are two transition methods available under the new standard, either cumulative effect or retrospective. In August 2015, the FASB issued ASU 2015-14 which defers the mandatory effective date by one year. The standard will be effective for us in the first quarter of 2018, with early adoption permitted, but not before the original effective date. We will adopt the new standard using the modified retrospective approach, which requires the standard be applied only to the most current period presented, with the cumulative effect of initially applying the standard recognized at the date of initial application. We do not expect that the adoption of ASU 2014-09 will have a significant impact to our consolidated financial statements or disclosures.

2. Equity Method Investments

Equity method investments as of September 30, 2015 and December 31, 2014, were as follows:



	September 30, 2015			December 31, 2014
(dollars in millions)	Carrying Value		Ownership Percentage	Carrying Value		Ownership Percentage
USG Boral Building Products	$	650	50%	$	689	50%
Other equity method investments (a)	44		33% - 50%	46		33% - 50%
Total equity method investments	$	694		$	735


(a)	This amount includes our investment in Knauf-USG of $37 million which as of September 30, 2015 is classified as assets held for sale and is included in other current assets.

Investment in USG Boral Building Products ("UBBP")

On February 27, 2014, we formed the 50/50 joint ventures, USG Boral Building Products Pte. Limited, a company organized under the laws of Singapore, and USG Boral Building Products Pty Limited, a company organized under the laws of Australia, with Boral Limited ("Boral"). These joint ventures are herein referred to as USG Boral Building Products, or UBBP. UBBP manufactures, distributes and sells certain building products, mines raw gypsum and sells natural and synthetic gypsum throughout Asia, Australasia and the Middle East (the "Territory"). The products that UBBP manufactures and distributes include products for wall, ceiling, floor lining and exterior systems that utilize gypsum, wallboard, referred to as plasterboard in the Territory, mineral fiber ceiling tiles, steel grid and studs and joint compound.

As consideration for our 50% ownership in UBBP, we (i) made a cash payment of $515 million to Boral, which includes a $500 million base price and $15 million of customary estimated working capital and net debt adjustments, (ii) contributed to UBBP our subsidiaries and joint venture investments in China, Singapore, India, Malaysia, New Zealand, Australia, the Middle East and Oman, see Note 15, and (iii) granted to UBBP licenses to use certain of our intellectual property rights in the Territory.

Table of Contents

We funded our cash payments with the net proceeds from our October 2013 issuance of $350 million of 5.875% senior notes and cash on hand.

In the event certain performance targets are satisfied by UBBP, we will be obligated to pay Boral scheduled earnout payments in an aggregate amount up to $75 million, comprised first of $25 million based on performance during the first three years after closing and then up to $50 million based on performance during the first five years after closing. We recorded a liability representing the present value of the first earnout payment. We have not recorded a liability for the second earnout payment as we have concluded that it is currently not probable that the five-year performance target will be achieved. If our conclusion on the probability of achievement were to change, we will record a liability representing the present value of the second earnout payment with a corresponding increase to our investment. As of September 30, 2015 and December 31, 2014, our liability for the earnout payments totaled $24 million and $23 million, respectively, and is included in other liabilities on our accompanying consolidated balance sheets.

We account for our 50% investment in UBBP using the equity method of accounting, and we initially measured its carrying value at cost of approximately $676 million as of February 27, 2014. Our existing wholly-owned subsidiaries and consolidated variable interest entities that were contributed into the joint ventures were deconsolidated resulting in a gain of $27 million, which is included in our consolidated statement of operations for the nine months ended September 30, 2014. Approximately $11 million of the gain relates to the remeasurement of our retained investment in the contributed subsidiaries to a fair value, determined using a discounted cash flow model with several inputs, including a weighted-average discount rate of approximately 11% and a weighted-average long-term growth rate of approximately 2%.

All of our investments accounted for under the equity method of accounting are initially recorded at cost, and subsequently adjusted for our share of the net income or loss and cash contributions and distributions to or from these entities. Because the underlying net assets in our investments are denominated in a foreign currency, translation gains or losses will impact the recorded value of our investments. Translation gains or losses recorded in other comprehensive income were as follows:



	Three months ended September 30,						Nine months ended September 30,
(in millions)	2015			2014			2015			2014
Translation loss	$	(35	)	$	(24	)	$	(54	)	$	(13	)

During the second quarter of 2015, UBBP's Board of Directors declared and UBBP paid cash dividends on earnings through March 2015 of which our 50% share totaled $18 million. We recorded the cash dividend in operating activities on our cash flow and intend to use the cash dividends to fund the first earnout payment described above. As of September 30, 2015, the amount of consolidated retained earnings which represents undistributed earnings from UBBP is $48 million.

Summarized financial information for our equity method investments is as follows:



	Three months ended September 30,				Nine months ended September 30,
(in millions)	2015		2014		2015		2014 (a)

(a)	Operating results are presented for UBBP for the seven months ended September 30, 2014.

Investment in Knauf-USG

On September 15, 2015, we entered into an agreement to sell our 50% interest in the Knauf-USG joint venture to our 50/50 joint venture partner, Knauf Aquapanel GmbH, a subsidiary of Gebr. Knauf Verwaltungsgesellschaft KG (Knauf) for

Table of Contents

€48 million in cash, approximately $54 million (as calculated using the exchange rate as of September 30, 2015). The Knauf-USG joint venture manufactures and distributes Aquapanel^® brand cement-based panels in Europe (excluding Turkey) and all countries that were part of the former Soviet Union. Affiliates of Knauf are the beneficial owners of approximately 10% of USG's outstanding shares of common stock.

The sale is expected to close in the fourth quarter of 2015 pending regulatory approval. Upon close of the sale, we anticipate recording a net gain in the range of $3 million to $7 million on disposition.

During the second quarter of 2015, our investment in the Knauf-USG joint venture met the criteria for asset held for sale. Accordingly, we have recorded our investment of $37 million as asset held for sale in other current assets on the consolidated balance sheet as of September 30, 2015. Our equity method income in the Knauf-USG joint venture was $2 million for both the nine months ended September 30, 2015 and 2014, respectively.

3. Long-Lived Asset Impairment Charges

Since 2007, we have continuously evaluated our manufacturing needs by considering the capacity of existing and idled plants and production lines, as well as capital projects for manufacturing facilities, relative to the demand assumptions included in our long-range plan. Although industry and economic factors have improved and we believe that the overall economic recovery is intact, they are improving at a slower pace than expected, requiring us to reconsider the future utilization of idled plants and production lines, and capital projects for manufacturing facilities. As a result, in the third quarter of 2014, we recorded asset impairment charges totaling $30 million, which includes the following:

(a) $16 million related to the carrying values of machinery, equipment and buildings at our temporarily idled gypsum quarry and wallboard production facility in Empire, Nevada and at our previously idled and now permanently closed gypsum wallboard line in New Orleans, Louisiana. In addition, in the third quarter 2014 we permanently closed our wallboard line in Detroit, Michigan. No impairment charge was recorded with respect to our wallboard line in Detroit, Michigan, as these assets were previously impaired at the time the plant was originally idled.

(b) $12 million related to previously incurred and capitalized costs for the construction of two future facilities which we do not anticipate will be built within our planning horizon.

(c) $2 million related to the carrying values of machinery, equipment and buildings at our previously idled and now permanently closed paper production line in Gypsum, Ohio.

The carrying values of the machinery, equipment and buildings at our temporarily idled facility in Empire, Nevada exceeded the estimated future undiscounted cash flows for the remaining useful lives of the assets due to slower than expected acceleration in the markets served by this facility and our forecasts regarding the timing and future rate of recovery in those markets. Based on these conditions, we do not anticipate that the carrying values of the assets at this facility would be recovered prior to end of the assets’ useful lives, and therefore fully impaired these assets. For the production line in Gypsum, Ohio that we deemed to be permanently closed, we fully impaired the long-lived assets specific to those lines.

The long-lived asset impairment charges relate solely to our Gypsum segment.

5.	Earnings (Loss) Per Share

Basic earnings (loss) per share is based on the weighted average number of common shares outstanding. Diluted earnings (loss) per share is based on the weighted average number of common shares outstanding plus the dilutive effect, if any, of market share units, or MSUs, performance shares, restricted stock units, or RSUs, stock options, deferred shares associated with our deferred compensation program for non-employee directors and, for the applicable periods, the potential conversion of our 10% convertible senior notes due 2018, which were converted into common stock in April 2014.

The reconciliation of basic earnings (loss) per share to diluted earnings (loss) per share is shown in the following table.



	Three months ended September 30,					Nine months ended September 30,

6.	Marketable Securities

Marketable securities are classified as available-for-sale securities and reported at fair value, with unrealized gains and losses excluded from earnings and reported in accumulated other comprehensive loss on our accompanying consolidated balance sheets. Proceeds received from sales and maturities of marketable securities were $132 million for the nine months ended September 30, 2015. Our investments in marketable securities consisted of the following:



	As of September 30, 2015				As of December 31, 2014
(millions)	Amortized Cost		Fair Value		Amortized Cost		Fair Value
Corporate debt securities	$	79	$	79	$	93	$	93

Certificates of deposit	11		11		18		18
Municipal debt securities	3		3		4		4
Total marketable securities	$	117	$	117	$	154	$	154

The realized and unrealized gains and losses for the three and nine months ended September 30, 2015 and 2014 were immaterial. Cost basis for securities sold are determined on a first-in-first-out basis.

Contractual maturities of marketable securities as of September 30, 2015 were as follows:



(millions)	Amortized Cost		Fair Value
Due in 1 year or less	$	89	$	89
Due in 1-5 years	28		28
Total marketable securities	$	117	$	117

Actual maturities may differ from the contractual maturities because issuers of the securities may have the right to prepay them.

7. Intangible Assets

Intangible assets are included in other assets on our accompanying consolidated balance sheets. Intangible assets with definite lives are amortized. These assets are summarized as follows:



	As of September 30, 2015							As of December 31, 2014
(millions)	Gross Carrying Amount		Accumulated Amortization			Net		Gross Carrying Amount		Accumulated Amortization			Net
Intangible Assets with Definite Lives:

Other	9		(7		)	2		9		(7		)	2
Total	$	79	$	(67	)	$	12	$	79	$	(61	)	$	18

Total amortization expense was $2 million and $6 million for the three and nine months ended September 30, 2015 and 2014, respectively. Estimated amortization expense for the remainder of 2015 and for future years is as follows:



(millions)	2015		2016		2017		2018 and thereafter
Estimated future amortization expense	$	2	$	7	$	2	$	1

Table of Contents

Intangible assets with indefinite lives are not amortized. These assets are summarized as follows:



	As of September 30, 2015							As of December 31, 2014

As of December 31, 2014, approximately $5 million of other indefinite-lived intangible assets met the criteria to be classified as held for sale and therefore were included in other current assets on our accompanying consolidated balance sheet. As of September 30, 2015, these indefinite-lived intangible assets were no longer recorded as held for sale.

8. Debt

Total debt, including the current portion of long-term debt, consisted of the following:



(millions)	September 30, 2015		December 31, 2014
5.5% senior notes due 2025	$	350	$	—

Industrial revenue bonds (due 2028 through 2034)	239		239
Total	$	2,188	$	2,209

REPURCHASE OF SENIOR NOTES

In the first quarter of 2015, we repurchased $350 million of our 8.375% Senior Notes due in 2018, or the 2018 Senior Notes, through both a cash tender offer and a subsequent notice of redemption of the remaining 2018 Senior Notes. On February 24, 2015, we completed a cash tender offer pursuant to which we repurchased $126 million of the 2018 Senior Notes for aggregate consideration, including tender offer premium and accrued and unpaid interest, of $135 million. On March 26, 2015, we repurchased the remaining $224 million of the 2018 Senior Notes for aggregate consideration, including premiums and accrued and unpaid interest, of $242 million. As a result of the repurchases, we recorded a loss on early extinguishment of debt of $19 million including premiums and write-off of deferred financing fees.

ISSUANCE OF SENIOR NOTES

On February 24, 2015 we issued $350 million of 5.5% senior notes due March 1, 2025, or the 2025 Senior Notes. The net proceeds from the issuance of the 2025 Senior Notes and cash on hand were used to fund the repurchases of the 2018 Senior Notes and all related costs and expenses.

The 2025 Senior Notes were recorded on the accompanying consolidated balance sheets at $350 million. We deferred approximately $6 million of financing costs that are being amortized to interest expense over the term of the notes. Our obligations under the 2025 Senior Notes are guaranteed on a senior unsecured basis by certain of our domestic subsidiaries. The notes are redeemable at any time, or in part from time to time, at our option on or after March 1, 2020 at stated redemption prices, plus any accrued and unpaid interest to the redemption date. In addition, we may redeem the notes at our option at any time prior to March 1, 2020, in whole or in part, at a redemption price equal to 100% of the principal amount of the notes being redeemed plus the applicable premium as of, and any accrued and unpaid interest on the principal amount being redeemed to, the redemption date.

The 2025 Senior Notes contain a provision the same as or similar to the provision in our other senior notes that requires us to offer to purchase those notes at 101% of their principal amount (plus accrued and unpaid interest) in the event of a change in control.

Table of Contents

The indenture governing the 2025 Senior Notes contains events of default, covenants and restrictions that are substantially the same as those governing our other senior notes, including a limitation on our ability and the ability of certain of our subsidiaries to create or incur secured indebtedness.

SHIP MORTGAGE FACILITY

In February 2015, as consideration for the consent of DVB Bank SE, as lender, agent and security trustee of the secured loan facility agreement, to allow Gypsum Transportation Limited, or GTL, to enter into certain future contracts of affreightment, GTL voluntarily repaid $2 million of the outstanding loan balance under its secured loan facility. The repayment provisions of the secured loan facility were not otherwise modified. The voluntary payment was not classified in the current portion of long-term debt on our accompanying consolidated balance sheet as of December 31, 2014. GTL also repaid $1 million in the first quarter of 2015 in accordance with the terms of the original loan facility agreement. In April 2015, in connection with the sale of two self-unloading vessels, GTL repaid the outstanding loan balance of $18 million. See Note 18 for discussion of GTL.

CREDIT FACILITY

Taking into account the most recent borrowing base calculation delivered under the credit facility, which reflects trade receivables and inventory as of September 30, 2015, and outstanding letters of credit, borrowings available under the credit facility were approximately $335 million, including $50 million for CGC. As of September 30, 2015 and during the quarter then-ended, there were no borrowings under the facility. Had there been any borrowings as of that date, the applicable interest rate would have been 2.08% for loans in the US and 2.54% for loans in Canada. Outstanding letters of credit totaled $49 million as of September 30, 2015.

The fair value of our debt was approximately $2.293 billion as of September 30, 2015 and $2.338 billion as of December 31, 2014. The fair values were based on quoted prices for identical or similar liabilities in markets that are not active or valuation models in which all significant inputs and value drivers are observable and, as a result, are classified as Level 2 inputs. See Note 10 for further discussion on fair value measurements and classifications.

As of September 30, 2015, we were in compliance with the covenants contained in our credit facilities.


9.	Derivative Instruments

We use derivative instruments to manage selected commodity price and foreign currency exposures as described below. We do not use derivative instruments for speculative trading purposes, and we typically do not hedge beyond three years. Cash flows from derivative instruments are included in net cash provided by operating activities in the consolidated statements of cash flows.

COMMODITY DERIVATIVE INSTRUMENTS

As of September 30, 2015, we had 25 million mmBTUs (millions of British Thermal Units) in aggregate notional amount of outstanding natural gas swap contracts to hedge forecasted purchases. All of these contracts mature by December 31, 2017. For contracts designated as cash flow hedges, the net unrealized loss that remained in accumulated other comprehensive income (loss), or AOCI, as of September 30, 2015 was $18 million and as of December 31, 2014 was $20 million. No ineffectiveness was recorded on contracts designated as cash flow hedges in the first nine months of both 2015 and 2014. Gains and losses on contracts designated as cash flow hedges are reclassified into earnings when the underlying forecasted transactions affect earnings. For contracts designated as cash flow hedges, we reassess the probability of the underlying forecasted transactions occurring on a quarterly basis. Changes in fair value on contracts not designated as cash flow hedges are recorded to earnings. The fair value of those contracts not designated as cash flow hedges was a $3 million unrealized loss as of September 30, 2015 and a $5 million unrealized loss as of December 31, 2014.

FOREIGN EXCHANGE DERIVATIVE INSTRUMENTS

We have foreign exchange forward contracts to hedge forecasted purchases of products and services denominated in foreign currencies. The notional amount of these contracts was $118 million as of September 30, 2015, and they mature by December 23, 2016. These forward contracts are designated as cash flow hedges and no ineffectiveness was recorded in the first nine months of both 2015 and 2014. Gains and losses on the contracts are reclassified into earnings when the underlying transactions affect earnings. The fair value of these contracts that remained in AOCI was an unrealized gain of $8 million and $3 million as of September 30, 2015 and December 31, 2014, respectively.

In the third quarter of 2015, we entered into foreign exchange forward contracts to hedge a portion of our net investment in our Knauf-USG joint venture. The notional amount of these contracts was $35 million as of September 30, 2015, and they mature on November 16, 2015. These forward contracts are designated as net investment hedges and no ineffectiveness was recorded in the third quarter of 2015. Gains and losses on derivatives designated as net investment hedges, to the extent they

Table of Contents

are effective as hedges, remain in AOCI until such point when the investment is either sold or liquidated. The fair value of these contracts that remained in AOCI was an immaterial gain as of September 30, 2015.

COUNTERPARTY RISK, MASTER NETTING ARRANGEMENTS AND BALANCE SHEET OFFSETTING

We are exposed to credit losses in the event of nonperformance by the counterparties to our derivative instruments. As of September 30, 2015, our derivatives were in a $12 million net liability position. All of our counterparties have investment grade credit ratings; accordingly, we anticipate that they will be able to fully satisfy their obligations under the contracts.

All of our derivative contracts are governed by master netting agreements negotiated between us and the counterparties that reduce our counterparty credit exposure. The agreements outline the conditions (such as credit ratings and net derivative fair values) upon which we, or the counterparties, are required to post collateral. As required by certain of our agreements, we had $18 million of collateral posted with our counterparties related to our derivatives as of September 30, 2015. Amounts paid as cash collateral are included in receivables on our accompanying consolidated balance sheet.

We have not adopted an accounting policy to offset fair value amounts related to derivative contracts under our master netting arrangements; therefore, individual derivative contracts are reflected on a gross basis, as either assets or liabilities, on our consolidated balance sheets, based on their fair value as of the balance sheet date.

10. Fair Value Measurements

Certain assets and liabilities are required to be recorded at fair value. There are three levels of inputs that may be used to measure fair value. Level 1 is defined as quoted prices for identical assets and liabilities in active markets. Level 2 is defined as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets. Level 3 is defined as valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable. Certain assets and liabilities are measured at fair value on a nonrecurring basis rather than on an ongoing basis, but are subject to fair value adjustments in certain circumstances, such as when there is evidence of impairment or when a new liability is being established that requires fair value measurement.

The cash equivalents shown in the table below primarily consist of money market funds that are valued based on quoted prices in active markets and, as a result, are classified as Level 1. Equity mutual funds are valued based on quoted markets in active markets and, as a result, are classified as Level 1. We use quoted prices, other readily observable market data and internally developed valuation models when valuing our marketable securities and derivatives and have classified them as Level 2. Marketable securities are valued using income and market value approaches and values are based on quoted prices or other observable market inputs received from data providers. The valuation process may include pricing matrices, or prices based upon yields, credit spreads or prices of securities of comparable quality, coupon, maturity and type. Derivatives are valued using the income approach including discounted-cash-flow models or a Black-Scholes option pricing model and readily observable market data. The inputs for the valuation models are obtained from data providers and include end-of-period spot and forward natural gas prices, foreign currency exchange rates, natural gas price volatility and LIBOR and swap rates for discounting the cash flows implied from the derivative contracts.

Our assets and liabilities measured at fair value on a recurring basis were as follows:



	Quoted Prices in Active Markets for Identical Assets (Level 1)				Significant Other Observable Inputs (Level 2)						Significant Unobservable Inputs (Level 3)				Total
(millions)	9/30/15		12/31/14		9/30/15			12/31/14			9/30/15		12/31/14		9/30/15			12/31/14

During the third quarter of 2014, we reviewed our property, plant and equipment for potential impairment by comparing the carrying values of those assets with their fair values as estimated using the future undiscounted cash flows for their remaining useful lives. As disclosed in Note 3, we recorded long-lived asset impairment charges of $30 million for the third quarter of 2014. We measured the fair value of the machinery, equipment and buildings as of September 30, 2014 using measurements classified as Level 3.

Net postretirement benefit	$	(6	)	$	(6	)	$	(18	)	$	(19	)

During the first nine months of 2015, we made cash contributions of $50 million to the USG Corporation Retirement Plan Trust, $6 million to our pension plan in Canada, and $4 million, in aggregate, to certain other domestic pension plans. We expect to make total contributions to our pension plans in 2015 of approximately $62 million.

12. Share-Based Compensation

During the first nine months of 2015, we granted share-based compensation in the form of market share units, or MSUs, performance shares, and restricted stock units, or RSUs, to eligible participants under our Long-Term Incentive Plan. We recognize expense on all share-based grants over the service period, which is the shorter of the period until the employees’ retirement eligibility dates and the service period of the award for awards expected to vest. Expense is generally reduced for estimated forfeitures. Awards granted during the first nine months of 2015 and assumptions used to determine fair value were as follows:



	MSUs			Performance Shares			RSUs
Awards granted	473,728			147,290			92,000
Weighted average fair value	$	30.06		$	30.63		$	28.66
Expected volatility	42.70		%	42.70		%	N/A
Risk-free rate (a)	1.09		%	1.09		%	N/A
Expected term (in years) (b)	2.95			2.95			N/A
Expected dividends	—			—			N/A


(a)	The risk-free rate was based on zero coupon U.S. government issues at the time of grant.


(b)	The expected term represents the period from the valuation date to the end of the performance period.

The MSUs granted during the first nine months of 2015 generally vest after a three-year period based on our actual stock price performance during such period. The number of MSUs earned will vary from zero to 150% of the number of MSUs awarded depending on the actual performance of our stock price. In the case of termination of employment due to death, disability or retirement during the performance period, vesting will be pro-rated based on the number of full months employed in 2015. Awards earned will be issued at the end of the three-year period. MSUs may vest earlier in the case of a change in control in most circumstances only if there is also a related loss of employment or diminution of duties. Each MSU earned will be settled in common stock.

We estimated the fair value of each MSU granted on the date of grant using a Monte Carlo simulation that used the assumptions noted in the table above. Volatility was based on stock price history immediately prior to grant for a period commensurate with the remaining life of the plan.

PERFORMANCE SHARES

The performance shares granted during the first nine months of 2015 generally vest after a three-year period based on our total stockholder return relative to the performance of the Dow Jones U.S. Construction and Materials Index, with adjustments to that index in certain circumstances, for the three-year period. The number of performance shares earned will vary from zero to 200% of the number awarded depending on that relative performance. Generally, vesting will be pro-rated based on the number of full months employed during the performance period in the case of death, disability, or retirement, and pro-rated awards earned will be issued at the end of the three-year period. Each performance share earned will be settled in common stock.

We estimated the fair value of each performance share granted on the date of grant using a Monte Carlo simulation that used the assumptions noted in the table above. Volatility was based on stock price history immediately prior to grant for a period commensurate with the remaining life of the plan.

RESTRICTED STOCK UNITS

The RSUs granted during the first nine months of 2015 vest after a specified number of years from the date of grant or at a specified date. Generally, RSUs may vest earlier in the case of death, disability, or a change in control, provided that RSUs granted after 2012 will vest upon a change in control in most circumstances only if there is also a related loss of employment or diminution of duties. Each RSU is settled in a share of our common stock after the vesting period. The fair value of each RSU granted is equal to the closing price of our common stock on the date of grant.

15.	Oman Investment

In June of 2012, we entered into a strategic partnership with the Zawawi Group in Oman to establish a mining operation by acquiring 55% of Zawawi Gypsum LLC, or ZGL, which holds the mining rights to a gypsum quarry in Salalah, Oman. Quarry mining operations commenced in October 2013. The second phase of the partnership is a 50/50 manufacturing venture, USG-Zawawi Drywall LLC, or ZDL, that now operates a low cost wallboard plant in Oman.

We accounted for the acquisition of the mining rights as an asset acquisition and measured our interest in the mining rights at our cost. We determined that both entities were variable interest entities (VIEs), and, as such, we consolidated the VIEs through February 27, 2014 when our interests in ZGL and ZDL were contributed to UBBP. See Note 2, Equity Method Investments.

16. Income Taxes

In the third quarter of 2015, we recorded an income tax benefit of approximately $1 million. In the United States, we are in a net operating loss carryforward position and our deferred income tax assets are subject to a valuation allowance. Therefore, any domestic income or loss before income taxes does not generate a corresponding income tax expense or benefit.

In the nine months ended September 30, 2015, we recorded an income tax benefit of approximately $2 million. The income tax benefit for the nine months reflects audit closures in certain foreign jurisdictions and the refundable credit for the alternative minimum tax (AMT) credit carryforward utilized on the federal income tax return, offset by state and local and foreign jurisdiction tax expense.

As of September 30, 2015, we had federal net operating loss, or NOL, carryforwards of approximately $1.790 billion that are available to offset future federal taxable income and will expire in the years 2026 through 2032, none of which are subject to Internal Revenue Code limitations under Section 382. In addition, as of that date, we had federal AMT credit carryforwards of approximately $43 million that are available to reduce future regular federal income taxes over an indefinite period. In order to fully realize these U.S. federal net deferred tax assets, taxable income of approximately $1.913 billion would need to be generated during the period before their expiration. In addition, we have federal foreign tax credit carryforwards of $8 million that will expire if unused in 2015.

As of September 30, 2015, we had a gross deferred tax asset related to our state NOLs and tax credit carryforwards of $238 million, of which $1 million will expire in 2015. The remainder will expire if unused in years 2016 through 2033. We also had NOL and tax credit carryforwards in various foreign jurisdictions in the amount of $1 million as of September 30, 2015, against which we have maintained a valuation allowance.

During periods prior to 2015, we established a valuation allowance against our deferred tax assets totaling $1.023 billion. During the first nine months of 2015, we recorded a decrease in the valuation allowance against our deferred tax assets of $75 million resulting in a deferred tax asset valuation allowance of $948 million as of September 30, 2015. The decrease in the valuation allowance primarily related to a decrease in composition of the underlying deferred tax assets based on year-to-date earnings, the use of NOL carryforwards offsetting those earnings, and the planned repatriation of undistributed foreign earnings for our shipping operations and equity method investment in Knauf-USG.

In assessing the requirement for, and amount of, a valuation allowance in accordance with the more-likely-than-not standard, we give appropriate consideration to all positive and negative evidence related to the realization of the deferred tax assets. During the fourth quarter of 2015, we may realize a four year cumulative accounting profit in the U.S. If this occurs, we will also consider all other positive and negative evidence to determine the realizability of our deferred tax assets and the need for a full, or partial, valuation allowance. Any reversal of our valuation allowance will favorably impact our results of operations in the period of reversal.

The Internal Revenue Code imposes limitations on a corporation’s ability to utilize NOLs if it experiences an “ownership change.” In general terms, an ownership change may result from transactions increasing the ownership of certain stockholders in the stock of a corporation by more than 50 percentage points over a three-year period. If we were to experience an ownership change, utilization of our NOLs would be subject to an annual limitation determined by multiplying the market value of our outstanding shares of stock at the time of the ownership change by the applicable long-term tax-exempt rate, which was 2.82% for September 2015. Any unused annual limitation may be carried over to later years within the allowed NOL carryforward period. The amount of the limitation may, under certain circumstances, be increased or decreased by built-in gains or losses held by us at the time of the change that are recognized in the five-year period after the change. Many states have similar limitations. If an ownership change had occurred as of September 30, 2015, our annual U.S. federal NOL utilization would have been limited to approximately $109 million per year.

17. Litigation

WALLBOARD PRICING CLASS ACTION LAWSUITS

In late 2012, USG Corporation and United States Gypsum Company were named as defendants in putative class action lawsuits alleging that since at least September 2011, U.S. wallboard manufacturers conspired to fix and raise the price of gypsum wallboard sold in the United States and to effectuate the alleged conspiracy by ending the practice of providing job quotes on wallboard. These lawsuits are consolidated for pretrial proceedings in multi-district litigation in the United States District Court for the Eastern District of Pennsylvania, under the title In re: Domestic Drywall Antitrust Litigation, MDL No. 2437. One group of plaintiffs brings their claims on behalf of a class of entities that purchased gypsum wallboard in the United States directly from any of the defendants or their affiliates from January 1, 2012 to the present. The second group of plaintiffs brings their claims on behalf of indirect purchasers of gypsum wallboard who from January 1, 2012 through the present indirectly purchased wallboard in the United States from the defendants or their affiliates for end use and not for resale. Similar lawsuits have been filed in Quebec, Ontario and British Columbia courts on behalf of purchasers of wallboard in Canada. The Canadian lawsuits also name as defendants CGC Inc., our Canadian operating subsidiary, as well as other Canadian and U.S. wallboard manufacturers.

USG has denied the allegations made in these wallboard pricing lawsuits, believes these cases are without merit, and that USG’s pricing and selling policies were and are made independently and in full compliance with the law. Class action antitrust litigation in the United States, however, is expensive, protracted, and carries the risk of triple damages and joint and several liability. To avoid the expense, risk and further distraction of management, in late 2014, we agreed to a settlement of the U.S. direct and indirect purchaser plaintiff class actions and in the third quarter of 2014, we recorded a $48 million charge for the settlements ($39.25 million for the direct purchaser settlement and $8.75 million for the indirect purchaser settlement). On August 20, 2015, the court entered final judgment orders approving both the direct and indirect purchaser settlements. No member of the direct purchaser class appealed from the final judgment order approving the direct purchaser settlement, and therefore, that settlement should be final. One person appealed from the final judgment order approving the indirect purchaser settlement, and therefore that settlement is not yet final. We believe that the appeal is without merit and that the indirect purchaser settlement order will be affirmed on appeal, but the indirect purchaser settlement will not become final unless and until the appeal is favorably resolved.

The settlement of the U.S. class action lawsuits described above does not include the Canadian lawsuits. At this stage of the Canadian lawsuits, we are not able to estimate the amount, if any, of any reasonably possible loss or range of reasonably possible losses. We believe, however, that these Canadian lawsuits will not have a material effect on our business, financial condition, operating results or cash flows.

In addition to the class action lawsuits, in the first quarter of 2015, USG and seven other wallboard manufacturers were named as defendants in a lawsuit filed in federal court in California by twelve homebuilders asserting individual claims similar to the claims asserted in the U.S. class action lawsuits. These homebuilders opted out of the class action settlements, and their lawsuit has been transferred to the United States District Court for the Eastern District of Pennsylvania that is presiding over the U.S. class action lawsuits. We believe that the cost, if any, of resolving these homebuilders’ claims will not materially increase our exposure above the $48 million agreed to in the U.S. class action settlements.

ENVIRONMENTAL LITIGATION

We have been notified by state and federal environmental protection agencies of possible involvement as one of numerous “potentially responsible parties” in a number of Superfund sites in the United States. As a potentially responsible party, we may be responsible to pay for some part of the cleanup of hazardous waste at those sites. In most of these sites, our involvement is expected to be minimal. In addition, we are involved in environmental cleanups of other property that we own or owned. As of both September 30, 2015 and December 31, 2014, we had an accrual of $16 million for our probable and reasonably estimable liability in connection with these matters. Our accruals take into account all known or estimated undiscounted costs associated with these sites, including site investigations and feasibility costs, site cleanup and remediation, certain legal costs, and fines and penalties, if any. However, we continue to review these accruals as additional information becomes available and revise them as appropriate. Based on the information known to us, we believe these environmental matters will not have a material effect on our business, financial condition, operating results or cash flows.

Table of Contents

OTHER LITIGATION

We are named as defendants in other claims and lawsuits arising from our operations, including claims and lawsuits arising from the operation of our vehicles, product performance or warranties, personal injury and commercial disputes. We believe that we have properly accrued for our probable liability in connection with these claims and suits, taking into account the probability of liability, whether our exposure can be reasonably estimated and, if so, our estimate of our liability or the range of our liability. We do not expect these or any other litigation matters involving USG to have a material effect on our business, financial condition, operating results or cash flows.

18. Gypsum Transportation Limited

In April 2015, we completed the sale of our two self-unloading ocean vessels owned by Gypsum Transportation Limited, or GTL, for $42 million and recorded a gain of $7 million on the disposition. With a portion of the proceeds from the sale, GTL repaid the outstanding loan balance of $18 million under GTL’s secured loan facility agreement with DVB Bank SE and paid applicable selling costs. Additionally, we returned the third vessel leased by GTL and paid $7 million of early termination costs which were previously accrued for in the fourth quarter of 2014. In the second quarter 2015, GTL incurred charges of $6 million to exit our shipping operations.

The net impact of the gain on the sale of the vessels and charges incurred to wind down the shipping operations of $1 million is recorded in “Gain on disposal of shipping operations, net” on the consolidated statement of operations.

GTL recorded operating profit of $0 million and $1 million for the three and nine months ended September 30, 2015, respectively, compared with operating profit of $5 million and $19 million for the three and nine months ended September 30, 2014, respectively.

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

In the following Management’s Discussion and Analysis of Financial Condition and Results of Operations, “USG,” “we,” “our” and “us” refer to USG Corporation, a Delaware corporation, and its subsidiaries included in the consolidated financial statements, except as otherwise indicated or as the context otherwise requires.

Overview

We are a leading manufacturer and distributor of building materials. We produce a wide range of products for use in new residential, new nonresidential, and residential and nonresidential repair and remodel construction as well as products used in certain industrial processes. We estimate that during the first nine months of 2015:


•	residential and nonresidential repair and remodel activity accounted for approximately 53% of our net sales,


•	new residential construction accounted for approximately 18% of our net sales,


•	new nonresidential construction accounted for approximately 24% of our net sales, and


•	other activities accounted for approximately 5% of our net sales.

SEGMENTS

Our operations are organized into four segments: Gypsum, Ceilings, Distribution and USG Boral Building Products, or UBBP.

Gypsum: Our Gypsum segment manufactures and markets gypsum and related products in the United States, Canada, Mexico and Latin America. It includes United States Gypsum Company, or U.S. Gypsum, in the United States, the gypsum business of CGC Inc., or CGC, in Canada, USG Mexico, S.A. de C.V., or USG Mexico, and Latin America. Gypsum’s products are used in a variety of building applications to finish the walls, ceilings and floors in residential, commercial and institutional construction and in certain industrial applications. The major product lines within the Gypsum segment are:



Wallboard	Sheetrock^® brand gypsum wallboard portfolio and Securock^® glass mat sheathing
Surfaces	Sheetrock^® brand joint compound, corner bead, joint tape, plaster
Substrates	Durock^® cement backerboard, Fiberock^® backerboard, Levelrock^® flooring, Securock^® glass mat roofing and commercial roof board, and industrial gypsum

Ceilings: Our Ceilings segment manufactures and markets interior systems products in the United States, Canada, Mexico and Latin America. Ceilings includes USG Interiors, LLC, or USG Interiors, the ceilings business of CGC, USG Mexico and Latin America. In addition, through February 27, 2014, it also included our businesses in the Asia-Pacific region (see paragraph below regarding UBBP), which were included in USG International. Ceilings is a leading supplier of interior ceilings products used primarily in commercial applications. Ceilings manufactures ceiling tile in the United States and ceiling grid in the United States, Canada and, through February 27, 2014, in the Asia-Pacific region. It markets ceiling tile and ceiling grid in the United States, Canada, Mexico, Latin America and, through February 27, 2014, in the Asia-Pacific region.

As discussed below under USG Boral Building Products, or UBBP, on February 27, 2014, we invested with Boral Limited, or Boral, in UBBP, and in connection therewith contributed to UBBP our operations in the Asia-Pacific region. As such, Ceilings includes the results and activities of our subsidiaries in the Asia-Pacific region only through February 27, 2014.

Distribution: Our Distribution segment consists of L&W Supply Corporation and its subsidiaries, or L&W Supply, a leading distributor of gypsum wallboard and other building materials in the United States. It is a service-oriented business that stocks a wide range of construction materials. It delivers less-than-truckload quantities of construction materials to job sites and places them in areas where work is being done, thereby reducing the need for handling by contractors.

USG Boral Building Products (UBBP): On February 27, 2014, we and certain of our subsidiaries formed the 50/50 joint ventures, USG Boral Building Products Pte. Limited, a company organized under the laws of Singapore, and USG Boral Building Products Pty Limited, a company organized under the laws of Australia, with Boral. These joint ventures are herein referred to as USG Boral Building Products. UBBP manufactures, distributes and sells certain building products, mines raw gypsum and sells natural and synthetic gypsum throughout Asia, Australasia and the Middle East (the "Territory"). UBBP

Table of Contents

manufactures and distributes products for wall, ceiling, floor lining and exterior systems that utilize gypsum, wallboard, referred to as plasterboard in the Territory, mineral fiber ceiling tiles, steel grid and studs and joint compound.

As consideration for our 50% ownership in UBBP, we (i) made a $515 million cash payment to Boral, which included a $500 million base price and $15 million of customary estimated working capital and net debt adjustments, (ii) contributed to UBBP our subsidiaries and joint venture investments in China, Singapore, India, Malaysia, New Zealand, Australia, the Middle East and Oman, and (iii) granted to UBBP licenses to use certain of our intellectual property rights in the Territory. In the event certain performance targets are satisfied by UBBP, we will be obligated to pay Boral scheduled earnout payments in an aggregate amount up to $75 million, comprised of $25 million based on performance during the first three years after closing and up to $50 million based on performance during the first five years after closing. We recorded a liability representing the present value of the first earnout payment. We have not recorded a liability for the second earnout payment as we have concluded that it is currently not probable that the five-year performance target will be achieved. If our conclusion on the probability of achievement were to change, we will record a liability representing the present value of the second earnout payment with a corresponding increase to our investment. As of September 30, 2015 and December 31, 2014, this liability totaled $24 million and $23 million, respectively, and is included in other liabilities on our accompanying consolidated balance sheets.

UBBP is currently targeting the distribution of at least 50% of combined after tax profits to USG and Boral in proportion to the respective ownership interests; provided, however, that UBBP will not pay dividends if such payments are, among other things, restricted pursuant to the terms of the credit facilities maintained by UBBP, inconsistent with the then-applicable strategic plan, or illegal. Through September 30, 2015, cash dividends of $36 million have been declared by UBBP's Board of Directors and paid by UBBP. Our share of these dividends is $18 million, which we intend to use to pay the first earnout payment described above.

Since formation, UBBP has been funded from its net cash flows from operations and third-party financing, and it is our intent that as an ongoing operation, UBBP will continue to self-fund.

As a result of the contribution of our wholly-owned subsidiaries in Singapore, India, Malaysia, New Zealand and Australia and our consolidated joint ventures in Oman, the net sales and operating profit attributable to these entities are no longer included in those corresponding line items on our consolidated statement of operations subsequent to February 27, 2014. Instead, our share of the equity income from UBBP is shown within income from equity method investments.

Our investments in UBBP are accounted for as equity method investments and were initially measured at cost. Our existing wholly-owned subsidiaries and consolidated variable interest entities that were contributed into the joint ventures were deconsolidated, which resulted in a gain of $27 million during the first quarter of 2014. Our investments in UBBP consummated on February 27, 2014, and as a result, only seven months of our share of equity income from UBBP is reflected in income from equity method investments for the nine months ended September 30, 2014.

Geographic Information: For the first nine months of 2015, we recorded $2.851 billion of net sales in our consolidated statement of operations, of which approximately 85% were attributable to the United States, approximately 10% were attributable to Canada and other foreign countries accounted for the remaining 5%. Net sales for UBBP for the first nine months of 2015 were $742 million, which were comprised of 34% to Australia, 20% to South Korea, 12% to China, 15% to Thailand, with other foreign countries accounted for the remaining 19%.

MARKET CONDITIONS AND OUTLOOK

Our businesses are cyclical in nature and sensitive to changes in general economic conditions, including conditions in the North American housing and construction-based markets and the markets in Asia and Australasia, which are our most significant markets. Our expansion via UBBP into the markets of Asia, Australasia, and the Middle East has significantly increased our exposure to the economic conditions in those areas. The markets we serve can be broadly categorized as new residential construction, new nonresidential construction and repair and remodel activity, which includes both residential and nonresidential construction.

For the new residential construction market in the United States, housing starts are a very good indicator of demand for our gypsum products. Installation of our gypsum products typically follows a housing start by 90 to 120 days. In September 2015, the seasonally-adjusted annualized rate of housing starts reported by the U.S. Census Bureau was 1,206,000 units, an increase from both 1,132,000 units reported for August 2015 and 1,152,000 units reported for July 2015. In comparison, housing starts for all of 2014 were 1,003,000 units. Most industry analysts believe that the recovery in new residential construction will continue, although the recovery over the next few years may be uneven and modest, and that over the longer term housing starts will begin to reach historical averages. Industry analysts’ forecasts for 2015 housing starts in the United States included in the most recent Blue Chip Economic Indicators are 1,100,000 to 1,160,000 units, based on the average of the

Table of Contents

bottom ten and top ten forecasts included in the report, respectively. We currently estimate that 2015 housing starts in the United States will be in the middle of the range of 1,000,000 to 1,200,000.

Demand for our products from new nonresidential construction is determined by floor space for which contracts are signed. Installation of gypsum and ceilings products typically follows signing of construction contracts by about 12 to 18 months. According to the most recent construction market forecast from Dodge Data & Analytics (formerly known as McGraw-Hill Construction), total floor space for which new nonresidential construction contracts were signed in the United States increased 12% in 2014 compared with 2013. This followed a 12% increase in 2013 compared with 2012 and an 11% increase in 2012 compared with 2011. Dodge Data & Analytics forecasts that total floor space for which new nonresidential construction contracts in the United States are signed will increase approximately 5% in 2015 from the 2014 level. We anticipate new nonresidential construction growth in our business sectors in 2015 compared to 2014 will be in the mid-single digits.

The repair and remodel market includes renovation of both residential and nonresidential buildings. As a result of the low levels of new home construction in recent years, this market currently accounts for the largest portion of our sales. Many buyers begin to remodel an existing home within two years of purchase. According to the National Association of Realtors, sales of existing homes in the United States were approximately 4.93 million units in 2014, reflecting a 3% decrease from the 2013 level of 5.09 million units. The seasonally adjusted annual rate of existing home sales was 5.55 million units in September 2015, which is second to the rate in July 2015 of 5.58 million as the highest level since February 2007. The September 2015 rate was 5% higher than the August 2015 rate of 5.30 million units, and 9% higher than the September 2014 revised rate of 5.10 million units. Existing home sales have increased year-over-year for twelve consecutive months. The generally rising levels of existing home sales and home resale values in recent years have contributed to an increase in demand for our products from the residential repair and remodel market. We currently estimate that overall repair and remodel spending growth in 2015, compared to 2014, will be in the low- to mid-single digits.

The rate of recovery in the new residential construction market, new nonresidential construction market and the repair and remodel market still remains uncertain and will depend on broader economic issues such as employment, household formation, housing price trends, availability of mortgage financing, interest rates, consumer confidence, job growth and discretionary business investment.

We expect modest improvement over the next twelve months in the construction industries of Canada and Mexico. Emerging markets, including those that are within the UBBP territory, provide opportunities for our operations to serve the increasing demand for products in these regions. Several market forecasters have predicted that China will lead construction materials demand growth over the next several years. Several other countries, including South Korea and Australia, are forecasted to experience steady growth as well. Although the rate of growth in certain emerging markets has slowed, we expect the growth in these markets to exceed the improvements in North America. We anticipate that the results from UBBP will enable us to dampen some of the future cyclicality in our business.

The housing and construction-based markets we serve are affected by broader economic issues such as employment, the availability of credit, lending practices, interest rates, availability of mortgage financing, income tax policy and consumer confidence and preference. An increase in levels of unemployment, restrictive lending practices, a decrease in consumer confidence or other economic conditions could have a material effect on our business, financial condition, operating results and cash flows. Our businesses are also affected by a variety of other factors beyond our control, including the inventory of unsold homes, the level of foreclosures, home resale rates, housing affordability, office and retail vacancy rates and foreign currency exchange rates. Since we operate in a variety of geographic markets, our businesses are subject to the economic conditions in each of these geographic markets. General economic downturns or localized downturns or financial concerns in the regions where we have operations may have a material adverse effect on our business, financial condition, results of operations and cash flows.

Our Gypsum segment has improved with the modest recovery in residential housing over the last three years although, it continues to be adversely affected by the low level of residential and other construction activity compared to historical averages. Our Distribution segment, which serves the residential and commercial markets, and our Ceilings segment, which primarily serves the commercial markets, have both showed some improvements. However, they continue to be adversely affected by the low levels of new commercial construction activity.

Industry shipments of gypsum board in the United States (including gypsum wallboard, other gypsum-related paneling products and imports), as reported by the Gypsum Association, were an estimated 16.4 billion square feet in the first nine months of 2015, up approximately 4% compared with 15.7 billion square feet in the first nine months of 2014. We estimate that industry shipments in the United States for all of 2015 will be approximately 22.3 billion square feet, up approximately 2% from 21.8 billion square feet in 2014.

Table of Contents

There is excess wallboard production capacity industry-wide in the United States. Industry capacity in the United States was approximately 32.8 billion square feet as of January 1, 2015. We estimate that the industry capacity utilization rate was approximately 67% and 63% during the first nine months of 2015 and 2014, respectively. Based on current industry trends and forecasts, demand for gypsum wallboard is expected to increase in 2015, but the magnitude of any increase will depend on the levels of housing starts and repair and remodel activity. We project that the industry capacity utilization rate will experience a modest increase in 2015 compared to 2014. Despite our realization of improvement in our average wallboard selling price, we could experience pressure on gypsum wallboard selling prices and our gross margins at such low levels of capacity utilization. U.S. Gypsum implemented a price increase for wallboard with the new not to exceed price beginning January 1, 2015 through October 31, 2015, which has since been extended. However, it is uncertain that we will be able to maintain the increase in our gypsum wallboard selling prices. If we are unable to maintain our price increases, our net sales and operating profit may be materially and adversely impacted.

NET SALES

Consolidated net sales for the third quarter of 2015 were flat compared with the third quarter of 2014. This reflects higher net sales for the Distribution segment of 5% offset by lower net sales at our Gypsum and Ceilings segments of 2% and 5%, respectively. The increased sales for our Distribution segment were due to higher volumes and selling prices. The lower levels of net sales for our Gypsum segment reflected lower sales in Canada and Mexico/Latin America which were unfavorably impacted by currency translation of $15 million and $8 million, respectively, and a decrease in sales by GTL of $20 million and related intra-segment eliminations of $1 million offset by higher sales due to higher volume and higher prices in U.S. Gypsum.

Table of Contents

The decrease in our Ceilings segment net sales reflect lower volume and price in the United States and the unfavorable impact of currency translation of $3 million.

Consolidated net sales for the first nine months of 2015 increased $81 million, or 3%, compared with the first nine months of 2014. The increase reflects higher sales for our Gypsum and Distribution segments of 1% and 7%, respectively. This is offset by a decrease in sales for our Ceilings segment of 2%. The higher levels of net sales for our Gypsum segment reflected higher volume and, to a lesser extent, higher selling prices, offset by a decrease in sales by GTL of $52 million and related intra-segment eliminations of $3 million and unfavorable currency translation of $49 million. The increased sales for our Distribution segment were due to higher volume and, to a lesser extent, higher selling prices. Net sales in 2014 for our Ceilings segment included $7 million in sales for our subsidiaries in Asia-Pacific, India and Oman that were contributed to UBBP on February 27, 2014. Excluding that impact, net sales for our Ceilings were flat over the comparative period, which reflected higher volume and price offset by unfavorable currency translation of $9 million.

GROSS PROFIT

Gross profit for the third quarter of 2015 increased $7 million, or 4%, compared with the third quarter of 2014. Gross profit as a percentage of net sales was 18.8% for the third quarter of 2015, compared with 18.1% for the third quarter of 2014. Gross profit in the third quarter of 2014 included $6 million of higher gross profit for GTL. Excluding this amount, gross profit increased $13 million, which was due to higher volume and selling prices and lower cost for U.S. Gypsum’s Sheetrock^® brand gypsum wallboard, higher volumes for U.S. Gypsum’s Sheetrock^® brand joint compound and higher gross profit for substrates products offset by lower volumes and selling prices and higher cost for ceiling tile and lower prices for ceiling grid.

Gross profit for the first nine months of 2015 increased $25 million, or 5%, compared with the first nine months of 2014. Gross profit as a percentage of net sales was 18.2% for the first nine months of 2015, compared with 17.8% for the first nine months of 2014. Gross profit in the first nine months of 2014 included a $12 million gain for the sale of surplus property, a $7 million noncash reversal of an asset retirement obligation and $21 million of higher gross profit for GTL. Excluding these amounts, gross profit increased $65 million due to higher volume and selling prices and lower cost for U.S. Gypsum’s Sheetrock^® brand gypsum wallboard and joint compound, higher gross profit for substrates products, higher selling prices and lower cost for ceiling tile, and higher volume for ceiling grid.

SELLING AND ADMINISTRATIVE EXPENSES

Selling and administrative expenses totaled $81 million in the third quarter of 2015 compared to $76 million in the third quarter of 2014. As a percentage of net sales, selling and administrative expenses increased to 8.3% for the third quarter of 2015 from 7.8% for the third quarter of 2014. The increase reflects higher compensation costs and higher sales commission expense partially offset by lower discretionary spend.

Selling and administrative expenses totaled $237 million in the first nine months of 2015 compared to $230 million in the first nine months of 2014. As a percentage of net sales, selling and administrative expenses remained unchanged at 8.3% for each of the comparative periods.

LITIGATION SETTLEMENT CHARGE

In the third quarter of 2014, we recorded a litigation settlement of $48 million related to settlement in principal of the U.S. wallboard pricing class action lawsuits. See Note 17 to our consolidated financial statements included in this report for additional detail.

LONG-LIVED ASSET IMPAIRMENT CHARGES

In the third quarter of 2014, we recorded asset impairment charges of $30 million related to certain manufacturing facilities and capitalized costs for the construction of future facilities, which we do not anticipate will be built within our planning horizon. See Note 3 to our consolidated financial statements included in this report for additional detail.

GAIN ON DISPOSAL OF SHIPPING OPERATIONS, NET

During the second quarter of 2015, we recorded a net gain on the disposal of our shipping operations of $1 million. This reflects a gain on sale of our two self-unloading vessels of $7 million and charges to wind down our shipping operations of $6 million. We do not expect GTL to have a financial impact going forward.

INCOME FROM EQUITY METHOD INVESTMENTS

Income from equity method investments in the third quarter of 2015 was $13 million, an increase of $1 million from the third quarter of 2014. We recorded $12 million of equity income from UBBP in both the third quarter of 2015 and 2014. The results from the joint venture reflect an improvement in operating profit as a result of higher volumes of ready-mix compound,

Table of Contents

increased conversion to NextGen cement board, decrease in variable costs due to lower gypsum, energy and metal costs, and lower advertising and administrative expenses offset by an unfavorable impact of foreign currency of $3 million.

Income from equity method investments in the first nine months of 2015 was $35 million, an increase of $15 million from the first nine months of 2014. The results for the nine months ended September 30, 2015 include nine months of activity while the results for the nine months ended September 30, 2014 included seven months of activity, as the joint ventures with Boral did not commence until February 27, 2014. The improved results for the joint venture for the year-to-date period are reflective of the improvements discussed above as well as continued progress on realizing targeted synergy savings and improved market adoption rate of lightweight products offset by an unfavorable impact of foreign currency of $6 million. Further contributing to the increase is the absence of our share of both $5 million, net of tax, of restructuring charges and $3 million, net of tax, of facility damage costs incurred in the second quarter of 2014.

INTEREST EXPENSE

Interest expense was $40 million in the third quarter of 2015, down $3 million, or 7%, from the third quarter of 2014 and was $123 million in the first nine months of 2015, down $12 million, or 9%, from the first nine months of 2014. The decrease in interest expense for both comparative periods primarily reflects lower debt levels and lower interest rates on our outstanding debt. The decline in both periods was driven by the conversion of $75 million of our 10% convertible senior notes into common stock in April 2014, the August 2014 repayment of $59 million of our 9.75% Senior Notes, the February 2015 repurchase of our 8.375% Senior Notes due 2018 and issuance of our 5.5% Senior Notes, the 2015 repayment of our ship mortgage facility and lower amortization of deferred administrative fees and debt discounts.

LOSS ON EXTINGUISHMENT OF DEBT

In the first quarter of 2015, we recorded a $19 million loss on the extinguishment of debt, including premiums and write-off of deferred financing fees, in connection with the tender offer and repurchase of our 8.375% Senior Notes due 2018.

GAIN ON DECONSOLIDATION OF SUBSIDIARIES

In the first quarter of 2014, we recognized a gain on the deconsolidation of subsidiaries of $27 million as a result of our contribution of our wholly-owned subsidiaries in Singapore, India, Malaysia, New Zealand and Australia and our consolidated joint ventures in Oman into UBBP.

INCOME TAX EXPENSE / (BENEFIT)

We recorded an income tax benefit of $1 million in the third quarter of 2015 from foreign, state and local jurisdictions compared to an income tax expense of $2 million for the third quarter of 2014. We recorded an income tax benefit of $2 million in the first nine months of 2015. The income tax benefit for the first nine months of 2015 reflects audit closures in certain foreign jurisdictions and the refundable credit for the alternative minimum tax credit carryforward utilized on the federal income tax return, offset slightly by state and local and foreign jurisdiction tax expense. Income tax expense in the first nine months of 2014 of $7 million reflects income taxes for certain foreign, state and local jurisdictions, including approximately$1 million of withholding taxes on property contributed to UBBP.

(a)	Operating profit (loss) for 2014 included long-lived asset impairment charges of $30 million and a litigation settlement charge of $48 million, for both the three and nine months of 2014. See Note 3 and 17, respectively.


(b)	Results for the first three months of 2014 have been recast to reflect our change in segments.

Table of Contents

United States: Net sales in the third quarter of 2015 were $517 million, up $23 million, or 5%, compared with the third quarter of 2014. The increase in net sales was due to the following:



	Sales				Volume			Price
(millions)	$		%		$	%		$	%
Change to Q3 2015 from Q3 2014
Sheetrock® brand gypsum wallboard	7		3	%	4	2	%	3	1	%

Roof board	1		9	%	1	9	%	—	—	%
Other	6
Total increase in net sales	$	23	5	%

The increase of $7 million from the third quarter of 2014 to the third quarter of 2015 in Sheetrock^® brand gypsum wallboard reflected increases in both shipments and average selling prices. The increased shipments reflect greater demand from big box retailers and specialty dealers. Our premium Sheetrock^® Brand UltraLight Panels accounted for 65% of all of our wallboard shipments during the third quarter of 2015, compared to 63% in the third quarter of 2014.

Sales of Sheetrock^® brand joint compound increased $5 million on increased volume. Sales of Durock^® brand cement backerboard increased $4 million which reflected both higher volumes and average selling price. Sales of roof board increased $1 million which reflected higher volume of Gyp-Fiber roof boards and Glass-Mat roof boards. The increase in Other reflected higher sales of other products of $6 million, which was due to product mix, and reflected higher sales of substrates products, none of which were individually significant.

Operating profit of $84 million was recorded in the third quarter of 2015 compared with operating loss of $2 million in the third quarter of 2014. The increase of $86 million in operating profit reflected the following:



	Operating Profit		Volume		Price		Cost
(millions)	$		$		$		$
Change to Q3 2015 from Q3 2014
Sheetrock^® brand gypsum wallboard	$	7	$	2	$	3	$	2

Durock^® brand cement board	1		—		2		(1		)
Roof board	1		—		—		1
Other	76
Total increase in operating profit	$	86

The increase in operating profit reflected gross profit improvement for Sheetrock^® brand gypsum wallboard, Sheetrock^®brand joint compound, Durock^® brand cement board and Gyp-Fiber and Glass-Mat roof board. The increased gross profit for Sheetrock^® brand gypsum wallboard reflected higher shipments and higher gross margin due to the January 1, 2015 price increase and increased sales of higher margin Sheetrock^® brand UltraLight Panel products. The decrease in cost of $2 million also contributed to the operating profit improvement and reflected a $1 million gain for asset retirement obligations and a $1 million decline in other costs. The per unit cost for U.S. Gypsum’s Sheetrock^® brand gypsum wallboard in the third quarter of 2015 as compared with the third quarter of 2014 included a per unit cost increase of 3% for raw materials, including paper and rock, and a per unit cost increase of 7% for fixed costs, including labor inflation, offset by a per unit cost decrease of 10% for energy costs, primarily due to natural gas.

The increase in other reflected the absence of a litigation settlement charge of $48 million and long-lived asset impairment charges of $30 million recorded in the third quarter of 2014. Other also included an increase in selling and administrative costs of $5 million partially offset by improved profitability of our substrates products of $3 million. The increase in selling and administrative costs was driven primarily by higher compensation costs offset by lower services and fees and marketing expenses.

Table of Contents

Canada: Net sales in the third quarter of 2015 were $79 million, a decrease of $11 million from $90 million in the third quarter of 2014. The change in sales reflects an increase in gypsum wallboard of $4 million offset by an unfavorable impact of currency translation of $15 million. Driving the increase in wallboard was an increase of 2% in volume and an increase of 8% in average selling prices. Operating profit in the third quarter of 2015 was $3 million, a decrease of $2 million from the third quarter of 2014. The decrease reflects an unfavorable impact of fluctuations in foreign currency of $3 million offset by higher average selling prices on gypsum wallboard. Lower margins on products other than gypsum wallboard, including joint treatment, further contributed to the decrease in operating profit.

Mexico / Latin America: Net sales for our gypsum businesses in Mexico and Latin America were $46 million for the third quarter of 2015, a decrease of $5 million from the third quarter of 2014. Mexico's net sales were negatively impacted by foreign currency translation of $8 million which was offset by increases in sales of gypsum wallboard of $2 million and Durock^® brand cement board of $1 million. Operating profit decreased to $3 million in the third quarter of 2015 from $5 million in the third quarter of 2014. The decrease reflected the negative impact of currency of $1 million and an increased miscellaneous costs of $3 million offset by higher margins on gypsum wallboard of $1 million and Durock^® brand cement board of $1 million.

Gypsum Transportation Limited: There were no sales for our shipping company, Gypsum Transportation Limited, or GTL, for the third quarter of 2015 compared to $20 million in the third quarter of 2014. Operating profit was $0 million in the third quarter of 2015 compared to an operating profit of $5 million in the third quarter of 2014. The decrease in both net sales and operating profit reflected the cessation of shipping activity under a long-term shipping contract in the fourth quarter of 2014. No sales were recorded in the third quarter of 2015 as our short-term shipping contract ended in March 2015 and we sold our two self-unloading vessels in April 2015.

Canadian Mining: Net sales for our mining operation in Little Narrows, Nova Scotia, Canada, were $2 million for the third quarter of 2015 and $2 million for the third quarter of 2014. Operating loss was $1 million in both the third quarter of 2015 and of 2014.

(b)	Results for the first three months of 2014 have been recast to reflect our change in segments.

Table of Contents

United States: Net sales for our domestic ceilings business in the third quarter of 2015 were $123 million, a decrease of$2 million, or 2%, from the third quarter of 2014. The decrease reflected the following:



	Sales					Volume					Price
(millions)	$			%		$			%		$			%
Change to Q3 2015 from Q3 2014
Ceiling grid	$	(1	)	(2	)%	$	—		—	%	$	(1	)	(2	)%

Other products	1
Total decrease in net sales	$	(2	)	(2	)%

The decrease of $1 million in sales of ceiling grid reflected lower average selling price. The decrease of $2 million in ceiling tile reflected decreases in both volume and average selling price.

Operating profit was $21 million for the third quarter of 2015, a decrease of $5 million, or 19%, from the third quarter of 2014. The increase reflected the following:



	Operating Profit			Volume			Price			Cost
(millions)	$			$			$			$

Ceiling grid	$	(1	)	$	—		$	(1	)	$	—
Ceiling tile	(4		)	(1		)	(1		)	(2		)
Total decrease in operating profit	$	(5	)

The decrease in operating profit reflects a decrease in gross profit for both ceiling grid and ceiling tile. The increase in cost for ceiling tile reflected higher per unit costs driven by a per unit cost increase of 10% in conversion costs primarily due to maintenance and 7% in fixed costs reflecting lower volumes offset by a per unit cost decrease of 9% in energy costs due to natural gas. Additionally, operating profit for the third quarter of 2014 was the strongest quarter in the history of the business.

USG International: As a result of our change in segments, USG International consists only of the results of our wholly-owned subsidiaries in the Asia-Pacific region and India and our consolidated joint ventures in Oman that were contributed in February 2014 as part of our investment in UBBP; therefore, results for USG International in the nine months ended September 30, 2014 represent the net sales and operating profit (loss) for those entities. Results for our Latin America businesses, previously included within USG International, are now included in "Mexico / Latin America" within Gypsum or Ceilings, as applicable.

Canada: Net sales of $13 million for the third quarter of 2015 decreased $2 million compared to the third quarter of 2014. The decrease reflected an unfavorable impact of currency translation of $2 million. Operating profit of $1 million decreased $1 million compared to the third quarter of 2014 primarily reflecting the impact of fluctuations in foreign currency and lower margins on ceiling tile.

Mexico / Latin America: Net sales of $9 million for the third quarter of 2015 decreased $1 million compared to the third quarter of 2014. The decrease reflects unfavorable impact of foreign currency translation of $1 million in Mexico. Operating profit of $2 million remained unchanged from the third quarter of 2014.

Net sales of metal products increased $4 million and net sales of all other products increased $8 million.

Operating profit was $9 million in the third quarter of 2015 compared with $4 million in the third quarter of 2014. The $5 million increase in operating profit was attributable to increased gross profit of $6 million on gypsum wallboard driven by increases in volume and margin of 3% and 7%, respectively, and increased gross profit of $4 million for ceilings and other products. Offsetting the improved gross profit is an increase of $3 million of selling and administrative expenses due to timing and an increase of $2 million of delivery expenses due to higher sales.

L&W Supply served its customers from 144 distribution branches in the United States as of September 30, 2015. In the third quarter of 2015, L&W closed two under performing branches in areas that are served by multiple branches.

Net sales and operating profit for UBBP and our share of the net income of UBBP were as follows:

UBBP is our 50/50 joint ventures with Boral and are accounted for as equity method investments. Our share of the net income of UBBP recorded in income from equity method investments in our consolidated statement of operations was $12 million for both the third quarter of 2015 and 2014.

The following is a discussion of UBBP's consolidated results for the third quarter of 2015 as compared to the third quarter of 2014.

Net sales for UBBP were $250 million in the third quarter of 2015 compared to $286 million for the third quarter of 2014. The decrease of $36 million reflects the unfavorable impact of currency translation of $42 million as well as normalization of plasterboard shipments in Korea and weakening economies in China, Indonesia and Thailand. Plasterboard shipments decreased to 1.13 billion square feet for the third quarter of 2015 from 1.14 billion square feet for the third quarter of 2014. Operating profit was $30 million in the third quarter of 2015 compared to $31 million for the third quarter of 2014. The decrease of $1 million in operating profit reflected lower sales discussed above and an unfavorable impact of foreign currency of $6 million offset by improved gross margins in Korea and Thailand. Also offsetting the decrease in operating profit was a decrease in variable costs and administrative expenses. Additionally, the joint venture experienced synergy savings and improved market performance of lightweight products.

Net sales in Asia and Australasia made up approximately 65% and 35%, respectively, of total net sales for UBBP. Net sales in South Korea, China, Thailand and Indonesia represented approximately 76% of Asia's net sales and plasterboard revenue accounted for approximately 70% of Asia's net sales.

CORPORATE

The operating loss for Corporate increased to $25 million in the third quarter of 2015 compared with $23 million in the third quarter of 2014 primarily due to an increase in incentive compensation.

Liquidity and Capital Resources

As of September 30, 2015, we had $450 million of cash and cash equivalents and marketable securities compared with $382 million as of December 31, 2014. See discussion below under Cash Flows for explanation of the change in cash and cash equivalents. Our total liquidity as of September 30, 2015 was $785 million (including $335 million of borrowing availability under our credit facilities) compared to $673 million as of December 31, 2014 (including $291 million of borrowing availability under our credit facilities). The change in availability under our credit facilities was primarily due to higher accounts receivable balances.

Our cash is invested in cash equivalents and marketable securities pursuant to an investment policy that has preservation of principal as its primary objective. The policy includes provisions regarding diversification, credit quality and maturity profile that are designed to minimize the overall risk profile of our investment portfolio. The securities in the portfolio are subject to normal market fluctuations. See Note 6 to the consolidated financial statements for additional information regarding our investments in marketable securities.

Total debt, consisting of senior notes and industrial revenue bonds amounted to $2.188 billion ($2.189 billion in aggregate principal amount less $1 million of unamortized original issue discount) as of September 30, 2015 and $2.209 billion ($2.210 billion in aggregate principal amount less $1 million of unamortized original issue discount) as of December 31, 2014. As of September 30, 2015 and during the nine months then ended, there were no borrowings under our revolving credit facility and no borrowings outstanding.

Our obligations under our credit facility are guaranteed by USG and its significant domestic subsidiaries and secured by their and USG’s trade receivables and inventory. CGC's obligations under the credit facility are secured by trade receivables and inventory of certain subsidiaries. The credit facility matures in October 2019. The credit facility is available to fund working capital needs and for other general corporate purposes.

The credit agreement allows for the borrowing of revolving loans and issuance of letters of credit (up to a maximum of $200 million at any time outstanding, in aggregate) to USG and its subsidiaries. The maximum principal amount of revolving loans and letters of credit that may be borrowed by USG may not exceed the lesser of (1) $450 million less the amount of outstanding loans and letters of credit owed by CGC and (2) the excess of (a) the domestic borrowing base determined by reference to the trade receivables and inventory of USG and its significant domestic subsidiaries minus (b) the amount, if any, by which of the outstanding balance of loans and letters of credit owed by CGC exceeds the CGC borrowing base determined by reference to the trade receivables and inventory of CGC and certain Canadian subsidiaries at such time. The maximum principal amount of revolving loans and letters of credit that may be borrowed by CGC at any time may not exceed the lesser of (1) $50 million and (2) the sum of the CGC borrowing base determined by reference to the trade receivables and inventory of CGC and certain Canadian subsidiaries, plus the domestic borrowing base determined by reference to the trade receivables and inventory of USG and its significant domestic subsidiaries, minus the amount of outstanding loans and letters of credit owed by USG at such time.

The credit agreement contains a financial covenant that would require us to maintain a minimum fixed charge coverage ratio of not less than 1.0 to 1.0 if the excess of the availability (as defined in the credit agreement) is less than an amount equal to 10% of the lesser of (a) the aggregate revolving commitment at such time and (b) the aggregate borrowing base at such time. As of September 30, 2015, our fixed charge coverage ratio was 1.66-to-1.0. Because we currently satisfy the required fixed charge coverage ratio, we are not required to maintain a minimum borrowing availability under the credit facility. Taking into account the most recent borrowing base calculation, borrowings available under the credit facility were approximately $335 million.

In the first quarter of 2015, we repurchased $350 million of our 8.375% Senior Notes due in 2018, or the 2018 Senior Notes, through both a cash tender offer and a subsequent redemption of the remaining 2018 Senior Notes. On February 24, 2015, we completed a cash tender offer pursuant to which we repurchased $126 million of the 2018 Senior Notes for aggregate consideration, including tender offer premium and accrued and unpaid interest, of $135 million. On March 26, 2015, we repurchased the remaining $224 million of the 2018 Senior Notes for aggregate consideration, including premium and accrued and unpaid interest, of $242 million. These repurchases and all related costs were funded with cash on hand and the first quarter 2015 issuance of $350 million of 5.50% Senior Notes due 2025.

Table of Contents

In the second quarter of 2015, we repaid the outstanding balance on our ship mortgage facility of $18 million with the proceeds from the sale of our two self-unloading vessels. We repaid $3 million of this facility in the first quarter of 2015 with cash on hand.

Our undistributed foreign earnings as of September 30, 2015 are considered permanently reinvested with the exception of earnings associated with our shipping operations and those associated with our equity method investment in Knauf-USG. The amount of cash and cash equivalents held by our foreign subsidiaries was $78 million as of September 30, 2015. Any repatriation of these funds to the U.S. would have an immaterial impact on our current tax rate due to our substantial net operating loss, or NOL, carryforwards and related valuation allowance.

CASH FLOWS

The following table presents a summary of our cash flows:



	Nine months ended September 30,
(millions)	2015			2014
Net cash provided by (used for):
Operating activities	$	153		$	80
Investing activities	3			(585		)
Financing activities	(44		)	(62		)
Discontinued operations	—			(1		)
Effect of exchange rate changes on cash	(7		)	(2		)
Net increase (decrease) in cash and cash equivalents	$	105		$	(570	)

Operating Activities: The increase in net cash provided by operating activities for the first nine months of 2015 compared to the first nine months of 2014 reflected improved profitability and the receipt of a cash dividend of $18 million from UBBP for earnings through March 2015. This is offset by a payment of $39 million pursuant to the settlement agreement with the direct purchaser class settlement, which was deposited into settlement fund escrow accounts pursuant to the settlement agreements in the first quarter of 2015 and was released upon final approval of the settlement agreement in the third quarter of 2015. This payment is reflected in the change of accrued expenses. Excluding this payment, our net cash outflow for accounts receivable and inventories, accounts payable and accrued expenses was lower in 2015 compared to 2014.

As of September 30, 2015, working capital (current assets less current liabilities) amounted to $841 million, and the ratio of current assets to current liabilities was 2.78-to-1. As of December 31, 2014, working capital amounted to $589 million, and the ratio of current assets to current liabilities was 2.05-to-1.

Investing Activities: Net cash provided by investing activities during the first nine months of 2015 was $3 million compared to net cash used for investing activities of $585 million during the first nine months of 2014. The change reflects a cash outflow in 2014 of $558 million for our investment in UBBP, consisting of a $500 million base purchase price, $15 million of customary estimated working capital and net debt adjustments, $22 million of transaction costs and $23 million of cash held by the wholly-owned subsidiaries that we contributed to UBBP.

Additionally, in the first half of 2015, we deposited $48 million into settlement fund escrow accounts pursuant to the settlement agreements with the direct and indirect purchaser class settlements. In the third quarter of 2015, the payment for the direct purchaser class settlement was released from escrow and recorded in operating activities as discussed above. The remaining $9 million in the escrow account for the indirect purchaser settlement was recorded as a cash outflow in investing activities for the nine months ended September 30, 2015.

The net activity of purchases and sales or maturities for marketable securities decreased to a cash inflow of $36 million for the nine months ended September 30, 2015 from a cash inflow of $40 million for the nine months ended September 30, 2014. Capital expenditures amounted to $72 million in the first nine months of 2015 compared with $88 million in the first nine months of 2014.

Approved capital expenditures for the replacement, modernization and expansion of operations totaled $46 million as of September 30, 2015 compared with $96 million as of December 31, 2014.

Table of Contents

Financing Activities: Net cash used for financing activities for the first nine months of 2015 was $44 million compared to $62 million in the first nine months of 2014. The decrease reflected $365 million paid to repurchase $350 million of our 8.375% Senior Notes due 2018 plus tender premium offset by the $344 million of proceeds received from the issuance of $350 million of 5.50% Senior Notes, net of debt issuance fees and $21 million used to repay our ship mortgage facility.

DEFINED BENEFIT PLANS

During the first nine months of 2015, we made cash contributions of $50 million to the USG Corporation Retirement Plan Trust, $6 million to our pension plan in Canada, and $4 million, in aggregate, to certain other domestic plans. We expect to make total contributions to our pension plans in 2015 of approximately $62 million.

LIQUIDITY OUTLOOK

In the first nine months of 2015, our investing cash outflows included $72 million of capital expenditures. In total for 2015, we plan to spend approximately $100 million on capital expenditures in the normal course of business. We expect to fund these expenditures with cash from operations or cash on hand.

Interest payments, based on our current level of outstanding debt, are expected to decrease to approximately $159 million in 2015 compared with $175 million in 2014 primarily due to the conversion of the remaining $75 million of our 10% convertible senior notes in April 2014, the repayment of our 9.75% senior notes in August 2014, the repurchase of our 2018 Senior Notes in February 2015, the issuance of our 5.50% Senior Notes in the first quarter of 2015, and the repayment of our ship mortgage facility in the second quarter of 2015.

Since formation, UBBP was funded from its net cash flow from operations and third-party financing, and it is our intent that as an ongoing operation, UBBP will continue to self-fund. During the second quarter of 2015, UBBP's Board of Directors declared and UBBP paid cash dividends on earnings through March 2015 of $36 million. Our share of these dividends is $18 million. We intend to use the dividends received to pay the earnout payment described in Note 2 to the consolidated financial statements.

In the third quarter of 2014, we recorded a $48 million accrual related to the settlement of the U.S. wallboard pricing class action lawsuit. In the first half of 2015, we paid $48 million, of which $9 million remains in escrow and was recorded as restricted cash as of September 30, 2015 on our accompanying consolidated balance sheet.

We believe that cash on hand, including cash equivalents and marketable securities, cash available from future operations and our credit facilities will provide sufficient liquidity to fund our operations for at least the next 12 months. Cash requirements include, among other things, capital expenditures, working capital needs, employee retirement plans funding, debt repayment and amortization and other contractual obligations.

Realization of Deferred Tax Asset

As of September 30, 2015, we had federal NOL carryforwards of approximately $1.790 billion that are available to offset future federal taxable income and will expire in the years 2026 through 2032. In addition, as of that date, we had federal AMT credit carryforwards of approximately $43 million that are available to reduce future regular federal income taxes over an indefinite period. In addition, we have federal foreign tax credit carryforwards of $8 million that will expire if unused in 2015.

For the nine months ended September 30, 2015, we decreased our valuation allowance by $75 million which resulted in a deferred tax asset valuation allowance of $948 million as of September 30, 2015. The decrease in the valuation allowance primarily related to a decrease in composition of the underlying deferred tax assets based on year-to-date earnings, the use of NOL carryforwards offsetting those earnings and the planned repatriation of undistributed foreign earnings for our shipping operations and the equity method investment in Knauf-USG. Changes in the valuation allowance will have no impact on our ability to utilize our U.S. federal and state NOL and tax credit carryforwards to offset future U.S. profits. We continue to believe that we ultimately will have sufficient U.S. profitability during the remaining NOL and tax credit carryforward periods to realize substantially all of the economic value of the federal NOLs and some of the state NOLs before they expire.

We reduce the carrying amounts of deferred tax assets by a valuation allowance if, based on the available evidence, it is more likely than not that such assets will not be realized. The need to establish valuation allowances for deferred tax assets is

Table of Contents

assessed periodically. In assessing the requirement for, and amount of, a valuation allowance in accordance with the more likely-than-not standard, we give appropriate consideration to all positive and negative evidence related to the realization of the deferred tax assets. This assessment considers, among other matters, the nature, frequency and severity of current and cumulative losses, forecasts of future profitability, the duration of statutory carryforward periods, our experience with operating loss and tax credit carryforwards not expiring unused and tax planning alternatives. A history of cumulative losses for a certain threshold period is a significant form of negative evidence used in our assessment. Consistent with practices in the home building and related industries, we have a policy of four years as our threshold period for cumulative losses.

We consider all positive and negative evidence to determine the realizability of our deferred tax assets and the need for a full, or partial, valuation allowance. A significant form of positive evidence is the realization of a four year cumulative accounting profit in the U.S. Another form of positive evidence would be our recent U.S. operating profit used in conjunction with the key indicators of demand of our products as discussed in Market Conditions and Outlook. Specifically, our outlook on residential, commercial and repair and remodel construction over our planning horizon is considered in calculating our projected taxable income necessary to realize our deferred tax assets. Additional positive evidence considered is our use of net operating loss carryforwards prior to expiration. The vast majority of these net operating losses have a statutory carryforward period of 15 – 20 years. We do not currently have any tax planning strategies that are used to support our estimates of future taxable income. Based upon these factors, we expect we may release the majority of our domestic valuation allowance by the end of 2015. Any reversal of our valuation allowance will favorably impact our results of operations in the period of reversal.

Legal Contingencies

We are named as defendants in litigation arising from our operations, including lawsuits arising from the operation of our vehicles and lawsuits arising from product performance or warranties, personal injury, and commercial disputes. USG Corporation, United States Gypsum Company and CGC Inc. have been named as defendants in class action lawsuits alleging that North American wallboard manufacturers conspired to fix the price of wallboard sold in the United States and Canada. We entered into settlement agreements with attorneys representing the direct and indirect purchaser plaintiff classes in the U.S. wallboard pricing lawsuits, for which USG recorded a $48 million charge in the third quarter of 2014 ($39.25 million for the direct purchaser class settlement and $8.75 million for the indirect purchaser class settlement). On August 20, 2015, the court entered final judgment orders approving both the direct and indirect purchaser settlements. No member of the direct purchaser class appealed from the final judgment order approving the direct purchaser settlement, and therefore, that settlement should be final. One person appealed from the final judgment order approving the indirect purchaser settlement, and therefore that settlement is not yet final. We believe that the appeal is without merit and that the indirect purchaser settlement order will be affirmed on appeal, but the indirect purchaser settlement will not become final unless and until the appeal is favorably resolved.

The settlements do not include the Canadian lawsuits to which CGC is a party. At this stage of the Canadian lawsuits, we are not able to estimate the amount, if any, of any reasonably possible loss or range of reasonably possible losses. We believe, however, that these Canadian lawsuits will not have a material effect on our results of operations, financial position, or cash flows.

In addition to the class action lawsuits, in the first quarter of 2015, USG and seven other wallboard manufacturers were named as defendants in a lawsuit filed by twelve homebuilders asserting individual claims similar to the claims asserted in the U.S. class action lawsuits. We believe that the cost, if any, of resolving these homebuilders’ claims will not materially increase our exposure above the $48 million agreed to in the U.S. class action settlements.

In the third quarter of 2015 United States Gypsum Company was served with a federal grand jury subpoena requesting the production of company records in connection with a federal investigation of the gypsum drywall industry. We believe the investigation, although a separate proceeding, is related to the same events at issue in the litigation discussed above. We intend to fully cooperate with the grand jury investigation We believe we acted in full compliance with the law, and we do not expect the resolution of this matter to result in any material adverse effect on our business, financial position, liquidity or results of operations; however, we can provide no assurances as to the scope, timing, or outcome of any such investigation.

See Note 17 to the consolidated financial statements for further information regarding the foregoing lawsuits and other legal matters.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We use derivative instruments to manage certain commodity price and foreign currency exposures. We do not use derivative instruments for speculative trading purposes, and we typically do not hedge beyond three years. See Note 9 to the consolidated financial statements for additional information regarding our financial exposures.

COMMODITY PRICE RISK

We use natural gas swaps and options contracts to manage our exposure to fluctuations in commodity prices associated with anticipated purchases of natural gas. Currently, a significant portion of our anticipated purchases of natural gas for 2015 and 2016 is hedged as well as a portion of our anticipated purchases of natural gas for 2017. The aggregate notional amount of these hedge contracts in place as of September 30, 2015 was 25 million mmBTUs (millions of British Thermal Units). We review our positions regularly and make adjustments as market and business conditions warrant. The fair value of these contracts was an unrealized loss of $20 million as of September 30, 2015. A sensitivity analysis was prepared to estimate the potential change in the fair value of our natural gas hedge contracts assuming a hypothetical 10% change in market prices. Based on the results of this analysis, which may differ from actual results, the potential change in the fair value of our natural gas hedge contracts as of September 30, 2015 was $8 million. This analysis does not consider the underlying exposure.

FOREIGN CURRENCY EXCHANGE RISK

A sensitivity analysis was prepared to estimate the potential change in the fair value of our foreign exchange forward contracts assuming a hypothetical 10% change in foreign exchange rates. Based on the results of this analysis, which may differ from actual results, the potential change in the fair value of our foreign exchange forward contracts as of September 30, 2015 was $12 million. This analysis does not consider the underlying exposure.

ITEM 4. CONTROLS AND PROCEDURES


(a)	Evaluation of disclosure controls and procedures.

Our Chief Executive Officer and Chief Financial Officer, after evaluating the effectiveness of our “disclosure controls and procedures” (as defined in Rule 13a-15(e) promulgated under the Securities Exchange Act of 1934, or the Act), have concluded that, as of the end of the quarter covered by this report, our disclosure controls and procedures were effective to provide reasonable assurance that information required to be disclosed by us in the reports that we file or submit under the Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by an issuer in the reports that it files or submits under the Act is accumulated and communicated to the issuer’s management, including its principal executive officer or officers and principal financial officer or officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.


(b)	Changes in internal control over financial reporting.

There were no changes in our “internal control over financial reporting” (as defined in Rule 13a-15(f) promulgated under the Act) identified in connection with the evaluation required by Rule 13a-15(d) promulgated under the Act that occurred during the fiscal quarter ended September 30, 2015 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
