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, 2014 are not necessarily indicative of the results of operations to be expected for the entire year.

On our consolidated statements of operations for the three months and nine months ended September 30, 2013, income from equity method investments, which was previously included in "Other income, net," is reflected as "Income from equity method investments" to conform to the current year presentation. On our consolidated statement of cash flow for the nine months ended September 30, 2013, income from equity method investments previously included in "Other, net" has been reclassified to "Income from equity method investments."

Our investment with Boral Limited in a 50/50 joint venture, USG Boral Building Products or UBBP, was consummated on February 27, 2014 (February 28, 2014 Eastern Standard Time (Australia)), 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.

Effective April 1, 2014, we changed the composition of our reportable segments to reflect the change in management over our businesses in Mexico and Latin America and the contribution of our businesses in Asia-Pacific, India and Oman into UBBP. Accordingly, our segments are now structured around our key products and business units: (1) Gypsum, (2) Ceilings, (3) Distribution and (4) UBBP. As a result of these changes, our Mexico and Latin America businesses have been combined, with their Gypsum results included within our Gypsum segment, previously referred to as North American Gypsum, and their Ceiling results included within our Ceilings segment, previously referred to as Worldwide Ceilings. Our prior period results have been recast to reflect these changes and present comparative year over year results. See Notes 2 and 4.

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, 2013, which we filed with the SEC on March 3, 2014.

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

In April 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2014-08, "Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity," which includes amendments that change the requirements for reporting discontinued operations and require additional disclosures about discontinued operations. Under the new guidance, only disposals representing a strategic shift in operations - that is, a major effect on the organization's operations and financial results - should be presented as discontinued operations. Examples include a disposal of a major geographic area, a major line of business, or a major equity method investment. Additionally, ASU 2014-08 requires expanded disclosures about discontinued operations that will provide financial statement users with more information about the assets, liabilities, income, and expenses of discontinued operations. This update is effective for us in the first quarter of 2015. We do not expect that the adoption of ASU 2014-08 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.” ASU 2014-09 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. The standard will be effective for us in the first quarter of 2017, with early adoption not permitted. There are two transition methods available under the new standard, either cumulative effect or retrospective. We are currently evaluating the impact of this ASU and have not yet selected a transition method.

Table of Contents

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.

2. Equity Method Investments

Equity method investments as of September 30, 2014 and December 31, 2013, were as follows:



	September 30, 2014			December 31, 2013
(dollars in millions)	Carrying Value		Ownership Percentage	Carrying Value		Ownership Percentage
USG Boral Building Products (a)	692		50%	N/A		N/A
Other equity method investments	47		33% - 50%	$	73	33% - 50%
Total equity method investments	$	739		$	73


(a)	The carrying value of our investment in UBBP as of September 30, 2014, includes transaction costs of approximately $32 million incurred in the fourth quarter of 2013 and first nine months of 2014.

Investment in USG Boral Building Products ("UBBP")

On February 27, 2014, we formed a 50/50 joint venture, USG Boral Building Products ("UBBP"), with Boral Limited ("Boral") and certain of its subsidiaries. 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 region, mineral fiber ceiling tiles, steel grid and studs and joint compound.

On February 27, 2014, as consideration for our 50% ownership in UBBP, we (i) made a cash payment of $513 million to Boral, which includes a $500 million base price and $13 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. We funded our cash payment 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. In October 2014, we paid an additional $2 million to Boral in conjunction with customary post-closing adjustments.

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 venture 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 preliminary 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%. Additionally, we recorded a liability of $23 million representing the present value of the first earnout payment, which is included in other liabilities on our accompanying consolidated balance sheet as of September 30, 2014. We are not currently required under applicable accounting guidance to record a liability for the second earnout payment, as such, a liability has not been recorded on our consolidated balance sheet as of September 30, 2014.

All of our investments accounted for under the equity method 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 investment and, for the nine months ended September 30, 2014, resulted in a net loss of $13 million recorded in accumulated other comprehensive income (loss). For the nine months ended September 30, 2014, our

Table of Contents

accompanying consolidated statement of operations includes $20 million of equity income, representing our share of seven months of results of UBBP of $19 million and our share of income from our other equity method investments of $1 million.

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

3. Long-Lived Asset Impairment Charges

Since we began idling plants in 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) impairment charges of $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) impairment charges of $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) impairment charges of $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 in the current period. 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.

4. Segments

As discussed in Note 1, effective April 1, 2014 we changed the composition of our reportable segments. Prior-year results have been recast to conform with the new presentation of reportable segments. Our operations are organized into four reportable segments: Gypsum (previously North American Gypsum), Ceilings (previously Worldwide Ceilings), Distribution (previously Building Products Distribution) and UBBP. See Note 2 for segment results for UBBP. Segment results for our Gypsum, Distribution and Ceilings segments were as follows:



	Three months ended September 30,						Nine months ended September 30,
(millions)	2014			2013 (c)			2014(c)			2013 (c)
Net Sales:
Gypsum	$	621		$	580		$	1,778		$	1,670
Ceilings ^(a)	137			146			392			428
Distribution	359			331			1,003			931
Eliminations	(145		)	(132		)	(403		)	(374		)
Total	$	972		$	925		$	2,770		$	2,655

Total	$	22		$	75		$	186		$	198


(a)	Ceilings' net sales and operating profit for the nine months ended September 30, 2014 includes the results, through February 27, 2014, of our wholly-owned subsidiaries and consolidated joint ventures that were contributed to UBBP.


(b)	Gypsum's operating profit for both the three and nine months ended September 30, 2014 included a litigation settlement charge of $48 million and long-lived asset impairment charges of $30 million. See Notes 17 and 3, respectively.


(c)	Net sales and operating profit (loss) have been recast for periods prior to April 1, 2014 to conform with the new presentation of reportable segments.

In our disclosure of total assets by reportable segment in Note 13 of our Annual Report on Form 10-K for the year ended December 31, 2013, we reflected all cash within Corporate. As part of the consideration for our investment in UBBP on February 27, 2014, we made a cash payment of $513 million to Boral and we contributed to UBBP certain wholly-owned subsidiaries and joint venture investments, collectively the "Contributed Entities." See further discussion in Note 2. Total assets of the Contributed Entities were $139 million, consisting of (a) total assets, net of cash, of our contributed wholly-owned subsidiaries and consolidated joint ventures and (b) our investments in the unconsolidated joint ventures. These assets were included within Worldwide Ceilings, which we now refer to as our Ceilings segment.

See Note 3 for information related to the long-lived asset impairment charges recorded in our Gypsum segment in the third quarter of 2014.

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 December 2013 and April 2014. See Note 8.

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,

In December 2013, we converted $325 million of our 10% convertible senior notes due 2018 into approximately 28.5 million common shares. In April 2014, we converted the remaining $75 million of these notes into approximately 6.6 million common shares. See further discussion in Note 8.

MSUs, performance shares, RSUs, stock options and common shares issuable upon conversion of our 10% convertible senior notes that were not included in the computation of diluted earnings (loss) per share for those periods because their inclusion would be anti-dilutive were as follows:

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 income (loss) on our consolidated balance sheets. Proceeds received from sales and maturities of marketable securities were $166 million for the nine months ended September 30, 2014. Our investments in marketable securities consisted of the following:



	As of September 30, 2014				As of December 31, 2013
(millions)	Amortized Cost		Fair Value		Amortized Cost		Fair Value
Corporate debt securities	$	60	$	60	$	87	$	87

Asset-backed debt securities	13		13		20		20
Certificates of deposit	15		15		17		17
Municipal debt securities	6		6		6		6
Total marketable securities	$	100	$	100	$	142	$	142

The realized and unrealized gains and losses for the three and nine months ended September 30, 2014 and 2013 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, 2014 were as follows:



(millions)	Amortized Cost		Fair Value
Due in 1 year or less	$	64	$	64
Due in 1-5 years	36		36
Total marketable securities	$	100	$	100

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 with definite lives are amortized. These assets are summarized as follows:



	As of September 30, 2014							As of December 31, 2013
(millions)	Gross Carrying Amount		Accumulated Amortization			Net		Gross Carrying Amount		Accumulated Amortization			Net
Intangible Assets with Definite Lives:

Total	$	79	$	(60	)	$	19	$	79	$	(54	)	$	25

Total amortization expense was $2 million and $6 million for the three and nine months ended September 30, 2014 and 2013, respectively. Estimated amortization expense for the remainder of 2014 and for future years is as follows:



(millions)	2014		2015		2016		2017		2018		2019 and thereafter
Estimated future amortization expense	$	1	$	7	$	7	$	2	$	1	$	1

Intangible assets are included in other assets on our consolidated balance sheets, except for approximately $5 million of other indefinite-lived intangible assets which met the criteria to be classified as held for sale during the second quarter of 2014 and therefore are included in other current assets on our consolidated balance sheet as of September 30, 2014.


8.	Debt

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



(millions)	September 30, 2014		December 31, 2013
5.875% senior notes due 2021	$	350	$	350
6.3% senior notes due 2016	500		500

Credit facilities of Oman joint ventures	—		11
Industrial revenue bonds (due 2028 through 2034)	239		239
Total	$	2,210	$	2,355

On August 1, 2014, we repaid the remaining of $59 million of principal balance of our 9.75% senior notes due 2014.

In March 2014, we issued a notice of redemption to redeem the remaining $75 million in aggregate principal amount of outstanding 10% convertible senior notes due 2018. As of March 31, 2014, the notes were recorded on our accompanying consolidated balance sheet at $72 million, net of debt discount of $3 million. The notes could either be (1) redeemed at a stated redemption price or (2) converted into shares of our common stock. The holders of all $75 million in notes called for redemption elected to convert their notes into shares of USG’s common stock. Accordingly, in April 2014, we issued an additional 6,578,946 shares of our common stock in connection with the conversion of the notes.

Our U.S. credit facility contains a single financial covenant that would require us to maintain a minimum fixed charge coverage ratio of no less than 1.1-to-1.0 if and for so long as the excess of the borrowing base over the outstanding borrowings under the credit agreement is less than the greater of (a) $40 million and (b) 15% of the lesser of (i) the aggregate revolving commitments at such time and (ii) the borrowing base at such time. As of September 30, 2014, our fixed charge coverage ratio was 1.14-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 delivered under the credit facility, which reflects trade receivables and inventory as of September 30, 2014, and outstanding letters of credit of $54 million as of September 30, 2014, borrowings available under the credit facility were approximately $311 million. As of September 30, 2014 and during the quarter then-ended, there were no borrowings under the facility.

borrowing base to add an additional reserve against the borrowing base in the amount of the unpaid principal balance of the 2014 Notes outstanding from time to time.

During the nine months ended September 30, 2014, there was an immaterial amount of borrowings outstanding under our Canadian credit agreement and no borrowings outstanding as of September 30, 2014. The U.S. dollar equivalent of borrowings available under this agreement as of September 30, 2014 was $35 million. On October 22, 2014, in connection with the amendment and restatement of our credit facility described below, we terminated our Canadian credit facility.

In June 2013, our joint ventures in Oman, which were fully consolidated at that time, each entered into separate secured credit agreements, which were guaranteed by us and our joint venture partner. As of December 31, 2013, there was $11 million in outstanding term loan borrowings under the credit agreements. During the first two months of 2014, an additional $3 million of term loans were borrowed under these agreements. In connection with our investment in UBBP on February 27, 2014, we contributed our joint ventures in Oman, and the corresponding credit facilities, to UBBP. See further description of our investment in UBBP in Note 2.

The fair value of our debt was approximately $2.362 billion as of September 30, 2014 and $2.659 billion as of December 31, 2013. 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, 2014, we were in compliance with the covenants contained in our credit facilities.

AMENDED AND RESTATED CREDIT FACILITY

On October 22, 2014, we amended and restated our credit facility in order to, among other things, join CGC, Inc., or CGC, as a party and to increase the maximum borrowing limit under the credit agreement from $400 million to $450 million (including a $50 million borrowing sublimit for CGC). As amended and restated, 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. Pursuant to the credit agreement, the maximum principal amount of revolving loans and letters of credit that may be borrowed by and/or be issued in favor USG and CGC at any time may fluctuate based upon two separate borrowing base calculations.

USG's obligations under the credit facility are guaranteed by USG and its significant domestic subsidiaries and secured by their and USG’s trade receivables and inventory. CGC's obligation's under the credit facility are secured by trade receivables and inventory of certain subsidiaries. The credit facility matures on October 22, 2019 unless terminated earlier in accordance with its terms. The credit facility is available to fund working capital needs and for other general corporate purposes..

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 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. We would be required to continue to comply with such financial covenant until availability under the credit agreement exceeds such minimum threshold for 30 consecutive calendar days thereafter.


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 two 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, 2014, we had 22 million mmBTUs (millions of British Thermal Units) in aggregate notional amount of outstanding natural gas swap and option contracts to hedge forecasted purchases. All of these contracts mature by December 31, 2016. 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, 2014 was $3 million. No ineffectiveness was recorded on contracts designated as cash flow hedges in the first nine months of 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

Table of Contents

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 an immaterial unrealized gain as of September 30, 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 $69 million as of September 30, 2014, and they mature by June 30, 2016. These forward contracts are designated as cash flow hedges and no ineffectiveness was recorded in the first nine months of 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 a $2 million unrealized gain as of September 30, 2014.

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, 2014, our derivatives were in a $1 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.

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 of September 30, 2014, we had $6 million of collateral posted with our counterparties related to our derivatives.

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, 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. We use quoted prices, other readily observable market data and internally developed valuation models when valuing our derivatives and marketable securities and have classified them as Level 2. 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. 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.

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)	9/30/14		12/31/13		9/30/14			12/31/13		9/30/14		12/31/13		9/30/14			12/31/13

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 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.

11. Employee Retirement Plans

The components of net pension and postretirement benefits costs are summarized in the following table:



	Three months ended September 30,						Nine months ended September 30,
(millions)	2014			2013			2014			2013
Pension:
Service cost of benefits earned	$	9		$	10		$	27		$	29
Interest cost on projected benefit obligation	16			16			49			47
Expected return on plan assets	(20		)	(19		)	(60		)	(57		)
Net amortization	7			11			19			34
Net pension cost	$	12		$	18		$	35		$	53
Postretirement:

Interest cost on projected benefit obligation	1			2			5			5
Net amortization	(8		)	(9		)	(26		)	(26		)
Net postretirement benefit	$	(6	)	$	(6	)	$	(19	)	$	(18	)

During the first nine months of 2014, we made cash contributions of $50 million to the USG Corporation Retirement Plan Trust, $8 million to our pension plan in Canada, and $2 million, in aggregate, to certain other domestic and foreign pension plans. We expect to make total contributions to our pension plans in 2014 of approximately $61 million.

In April 2014, we amended our U.S. postretirement benefit plan for those retiree medical plan participants who are pre-65 retirees, to defer the effective date that requires participants to begin purchasing individual coverage in the Affordable Insurance Exchanges or individual Medicare marketplace using a company-funded subsidy from January 1, 2015 to January 1, 2016. The financial statement impact of the plan amendment was immaterial.

In the fourth quarter of 2014, we expect to incur a settlement charge between $12 million and $14 million with respect to an early pension settlement for USG (U.K.) Ltd.’s pension plan that was previously frozen to permanently eliminate future benefit accruals. The settlement charge will be calculated on the day the annuity purchase occurs.

12. Share-Based Compensation

During the first nine months of 2014, 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 2014 and assumptions used to determine fair value were as follows:



	MSUs			Performance Shares			RSUs
Awards granted	364,180			111,287			57,500
Weighted average fair value	$	40.20		$	46.46		$	33.37
Expected volatility	54.93		%	54.93		%	N/A
Risk-free rate (a)	0.63		%	0.63		%	N/A
Expected term (in years) (b)	2.94			2.94			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.

MARKET SHARE UNITS

The MSUs granted during the first nine months of 2014 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 2014.

Table of Contents

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 2014 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. Expected volatility was based on implied volatility of our traded options and the daily historical volatilities of our peer group.

RESTRICTED STOCK UNITS

The RSUs granted during the first nine months of 2014 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, retirement 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.

13. Supplemental Balance Sheet Information

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, to build and operate a low cost wallboard plant in Oman. Wallboard production operations are expected to commence by the end of 2014.

We accounted for the acquisition of the mining rights as an asset acquisition and measured our interest in the mining rights at our cost. The mining rights are depleted based upon tonnage mined relative to the total probable capacity in the quarry, and are presented within total property, plant and equipment in our accompanying consolidated balance sheet as of December 31, 2013. 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.

As of December 31, 2013, other liabilities included approximately $8 million of loans payable and the related accrued interest due to the joint venture partner. We contributed our Oman joint ventures, including these loans, to UBBP on February 27, 2014; therefore, the loans payable are no longer reflected on our balance sheet as of September 30, 2014. Also as a result of our contribution of our Oman joint ventures to UBBP, non-controlling interest within shareholders' equity decreased by approximately $24 million.

See Note 8 for a description of the credit facilities entered into by our joint ventures in Oman in June 2013.


16.	Income Taxes

In the third quarter of 2014, we had income tax expense of approximately $2 million from foreign, state and local jurisdictions. 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 income or loss before income taxes does not generate a corresponding income tax expense or benefit. Income tax expense in the current quarter reflects income taxes for certain foreign, state and local jurisdictions.

For the first nine months of 2014, we had income tax expense of $7 million, which primarily reflects income taxes for certain foreign, state and local jurisdictions, including approximately $1 million of withholding taxes on property contributed to UBBP. See Note 2.

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. As of September 30, 2014, we had federal net operating loss, or NOL, carryforwards of approximately $1.993 billion that are available to offset future federal taxable income and will expire in the years 2026 through 2033, 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 $45 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 $2.122 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 in 2015.

As of September 30, 2014, we had a gross deferred tax asset related to our state NOLs and tax credit carryforwards of $269 million, of which $11 million will expire in 2014. The remainder will expire if unused in years 2015 through 2033. We also had NOL and tax credit carryforwards in various foreign jurisdictions in the amount of $2 million as of September 30, 2014, against which we have maintained a valuation allowance.

During periods prior to 2014, we established a valuation allowance against our deferred tax assets totaling $995 million. During the first nine months of 2014, we recorded a decrease in the valuation allowance against our deferred tax assets of $34 million. Approximately $11 million of the decrease related to the realizability of our deferred tax assets due to state law changes. The other $23 million of the decrease resulted from a reduction in the gross value of our deferred tax assets. As a result of both decreases, and based upon an evaluation of all available evidence, we recorded corresponding reductions in the valuation allowance, resulting in no net impact to our consolidated statement of operations. The decreases in the valuation allowance in 2014 resulted in a deferred tax asset valuation allowance of $961 million as of September 30, 2014.

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

Table of Contents

was 3.06% for September 2014. 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, 2014, our annual U.S. federal NOL utilization would have been limited to approximately $122 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 purports to represent 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 purports to bring their claims and seek damages on behalf of indirect purchasers of gypsum wallboard. These indirect purchaser plaintiffs seek to certify a separate class of persons or entities 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.

In the fall of 2013, similar lawsuits were filed in Quebec and Ontario courts on behalf of purchasers of wallboard in Canada. These Canadian lawsuits also name as defendants CGC,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 actions were at all times lawful. U.S. antitrust litigation, however, is expensive and protracted, with inherent risks and uncertainties, including the potential of triple damages and joint and several liability. To avoid these expenses, risks and further distraction of management, in October 2014, we entered into a settlement agreement in principle with the attorneys representing the direct and indirect purchaser plaintiffs in the U.S. wallboard pricing lawsuits. Pursuant to the settlement in principle, which is subject to finalization of a settlement agreement and court approval, USG will pay a total of $48 million to resolve the U.S. direct and indirect purchaser cases. Accordingly we have recorded a $48 million charge in the third quarter of 2014 related to this settlement. If we are unable to settle the U.S. litigation under the terms currently contemplated, or at all, there can be no assurance that the outcome of these lawsuits will not have a material effect on our business, financial condition, operating results or cash flows.

The settlement 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 results of operations, financial position, or cash flows.

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 September 30, 2014 and December 31, 2013, we had an accrual of $16 million and $18 million, respectively, 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 results of operations, financial position or cash flows.

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 results of operations, financial position or cash flows.

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 2014:


•	residential and nonresidential repair and remodel activity accounted for approximately 49% of our net sales,


•	new residential construction accounted for approximately 27% of our net sales,


•	new nonresidential construction accounted for approximately 22% of our net sales, and


•	other activities accounted for approximately 2% of our net sales.

SEGMENTS

Effective April 1, 2014, we changed the composition of our reportable segments to reflect the change in management over our businesses in Mexico and Latin America and the contribution of our businesses in Asia-Pacific, India and Oman into a 50/50 joint venture, USG Boral Building Products, or UBBP. See further discussion below under Ceilings and Equity Method Investments. As a result of these changes, our Mexico and Latin America businesses have been combined, with their Gypsum results within our Gypsum segment, previously referred to as North American Gypsum, and their Ceiling results included within our Ceilings segment, previously referred to as Worldwide Ceilings. Our prior period results have been recast to reflect these changes and present comparative year-over-year results.

Our operations are organized into four reportable segments structured around our key products and business units: Gypsum, Ceilings, Distribution and UBBP.

Gypsum: Previously referred to as North American Gypsum, our Gypsum reportable 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, the gypsum businesses of USG Mexico, S.A. de C.V., or USG Mexico along with our gypsum businesses in 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. Its major product lines include SHEETROCK^® brand gypsum wallboard, a line of joint compounds used for finishing wallboard joints also sold under the SHEETROCK^® brand name, DUROCK^® brand cement board, 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.

Ceilings: Previously referred to as Worldwide Ceilings, our Ceilings reportable 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, and our ceilings businesses in 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 further described below under USG Boral Building Products, on February 27, 2014, we invested with Boral Limited ("Boral") in USG Boral Building Products, and in connection therewith contributed to UBBP our operations in the Asia-Pacific region. UBBP is accounted for as an equity method investment. As such, Ceilings includes the results and activities of our subsidiaries in the Asia-Pacific region only through February 27, 2014.

Table of Contents

Distribution: Previously referred to as Building Products Distribution, our Distribution reportable segment consists of L&W Supply Corporation and its subsidiaries, or L&W Supply, the 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 formed a 50/50 joint venture, UBBP, with Boral and certain of its subsidiaries. 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 region, mineral fiber ceiling tiles, steel grid and studs and joint compound.

As consideration for our 50% ownership in UBBP, we (i) made a $513 million cash payment to Boral, which included a $500 million base price and $13 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. We funded our cash payment 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 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. In October 2014, we paid an additional $2 million to Boral in conjunction with customary post-closing adjustments.

UBBP is targeting the distribution of 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, 2014, no dividends have been declared or paid by UBBP. The amount and timing of any distribution is currently unknown.

UBBP is operated in accordance with the terms of a shareholders’ agreement. From February 27, 2014 through September 30, 2014, UBBP was 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 on February 27, 2014, 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 on a going forward basis. Instead, our share of the equity income from UBBP is shown within income from equity method investments.

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

Geographic Information: For the first nine months of 2014, we recorded $2,770 million of net sales in our consolidated statement of operations, of which approximately 84% were attributable to the United States, approximately 9% were attributable to Canada and other foreign countries accounted for the remaining 7%. Net sales for UBBP for the period from February 27, 2014, the date of our investment in UBBP, to September 30, 2014, were $655 million, of which approximately 65% and 35% were attributable to Asia and Australasia, respectively.

MARKET CONDITIONS AND OUTLOOK

Our businesses are cyclical in nature and sensitive to changes in general economic conditions, including, in particular, conditions in the North American housing and construction-based markets, which are our most significant markets. 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, 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 2014, the seasonally-adjusted annualized rate of housing starts was reported by the U.S. Census Bureau to have increased to 1,017,000 units, compared to 957,000 units reported for August 2014 and 1,098,000 units reported for July 2014. In comparison, housing starts for 2013 were 925,000 units. Industry analysts believe that the recovery in new residential construction will continue to be uneven and modest over the next few years, but over the longer term housing starts will begin to reach historical averages. Industry analysts’ forecasts for 2014 housing starts in the United States included in the most recent Blue Chip Economic Indicators are 980,000 to 1,050,000 units, based on the average of the bottom ten and top ten forecasts included in the report, respectively. We currently estimate that 2014 housing starts in the United States will be in the lower end of the range of 1,000,000 to 1,100,000 units.

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 McGraw-Hill Construction's most recent construction market forecast, total floor space for which new nonresidential construction contracts were signed in the United States increased 9% in 2013 compared with 2012. This followed a 10% increase in 2012 compared with 2011 and a 3% increase in 2011 compared with 2010. McGraw-Hill Construction forecasts that total floor space for which new nonresidential construction contracts in the United States are signed will increase approximately 8% in 2014 from the 2013 level. McGraw-Hill's forecast includes several building types which do not generate significant demand for our products; therefore, we anticipate new nonresidential construction growth in our business sectors in 2014 compared to 2013 will be in the low to 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 increased to approximately 5.09 million units in 2013, the highest level since 2006, reflecting a 9.2% increase from the 2012 level of 4.66 million units. The seasonally adjusted annual rate of existing home sales was 5.17 million units in September 2014. This was 2% higher than the August 2014 rate of 5.05 million units, and 2% lower than the September 2013 rate of 5.26 million units. Although sales of existing homes in 2014 softened, 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 2014, compared to 2013, will be in the 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, foreclosures, house price trends, availability of mortgage financing, interest rates, income tax policy, consumer confidence, lease turnover rates, discretionary business investment, job growth and governmental building-related expenditures.

As discussed above, UBBP manufactures, distributes and sells certain building products, mines raw gypsum and sells natural and synthetic gypsum throughout Asia, Australasia and the Middle East. As of December 2013, the weighted-average GDP annual growth rate for the markets served by UBBP, as reported by the World Bank, was approximately 8%.

The housing and construction-based markets we serve are affected by economic conditions, the availability of credit, lending practices, interest rates, the unemployment rate and consumer confidence. An increase in interest rates, high 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 effect on our business, financial condition, results of operations and cash flows.

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 15.7 billion square feet in the first nine months of 2014, up approximately 5% compared with 15.0 billion square feet in the first nine months of 2013. We estimate that industry shipments in the United States for all of 2014 will be in the range of 22 to 23 billion, compared to 20.9 billion square feet in 2013.

U.S. Gypsum shipped 3.87 billion square feet of SHEETROCK^® brand gypsum wallboard in the first nine months of 2014, a 3% increase from 3.76 billion square feet in the first nine months of 2013. U.S. Gypsum’s share of the gypsum board market in the United States (which includes for comparability its shipments of SHEETROCK^® brand gypsum wallboard, FIBEROCK^® brand gypsum fiber panels and SECUROCK^®brand glass mat sheathing), based on industry shipments as reported by the Gypsum Association, was approximately 26% in the third quarter of 2014, compared to 26% in the third quarter of 2013, and 26% in the second quarter of 2014.

There is excess wallboard production capacity industry-wide in the United States. Industry capacity in the United States was approximately 32.7 billion square feet as of January 1, 2014. We estimate that the industry capacity utilization rate was approximately 63% during the first nine months of 2014 compared to 58% during the first nine months of 2013, and 73% in the fourth quarter of 2013. Based on current industry trends and forecasts, demand for gypsum wallboard is expected to increase in 2014, but the magnitude of any increase will be dependent primarily on the levels of housing starts and repair and remodel activity. We project that the industry capacity utilization rate over the balance of 2014 will improve commensurate with rising demand. Despite our realization of improvement in our average wallboard selling price, we could experience pressure on gypsum wallboard selling prices and our gross margins particularly if capacity utilization do not improve. In early 2014, as it did in 2013 and 2012, U.S. Gypsum implemented a price increase for wallboard with the new not to exceed price being set for the year. However, it is uncertain that we will be able to maintain the increase in our gypsum wallboard selling price. If we are unable to maintain our prices increases, our net sales and operating profit may be materially impacted.

IMPAIRMENTS

Since we began idling plants in 2007, we have continuously evaluated USG’s manufacturing needs by considering the capacity of existing plants 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. Since 2007, we have temporarily idled or permanently closed approximately 3.8 billion square feet of our highest-cost wallboard manufacturing capacity. 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 both idled plants and production lines and capital projects for manufacturing facilities. During the nine months ended September 30, 2014, we recorded $30 million of long-lived asset impairment charges. See Note 3 to our consolidated financial statements included in this report for additional detail.

Historically, the housing and other construction markets that we serve have been deeply cyclical. Downturns in demand are typically steep and last several years, but they have typically been followed by periods of strong recovery. If the current recovery results in increases in demand similar to those realized in recoveries from past cycles, we believe we will generate significant cash flows when our markets fully recover. However, this recovery could be slower than recoveries in the past, as the most recent downturn was especially steep. We regularly monitor forecasts prepared by external economic forecasters and review our facilities and other assets to determine which of them, if any, are impaired under applicable accounting rules. If the recovery in our markets is delayed, or we experience a future downturn in the housing and construction-based markets, material write-downs or impairment charges may be required in the future. The magnitude, likelihood and timing of those possible charges would be dependent on the severity and duration of a downturn, should a downturn materialize, and cannot be determined at this time. Any material restructuring or impairment charges, including write-downs of property, plant and equipment, could have a material effect on our results of operations and financial condition. We will continue to monitor economic forecasts and their effect on our facilities to determine whether any of our assets are impaired.

NET SALES

Consolidated net sales for the third quarter of 2014 increased $47 million, or 5%, compared with the third quarter of 2013, reflecting higher sales for our Gypsum and Distribution segments, offset by lower sales for our Ceilings segment. Net sales increased 7% and 8% for our Gypsum and Distribution segments, respectively, and decreased 6% for our Ceilings segment. The higher levels of net sales for our Gypsum and Distribution segments reflected higher selling prices and, to a lesser extent, higher volumes. Lower net sales for our Ceilings segment primarily reflected the absence of net sales for our subsidiaries in

Table of Contents

Asia-Pacific, India and Oman that were contributed to UBBP on February 27, 2014. Excluding those sales, net sales for our Ceilings segment increased 3%, primarily driven by higher volumes of ceiling tile and higher average selling prices for ceiling tile and ceiling grid in the United States.

Consolidated net sales for the first nine months of 2014 increased $115 million, or 4%, compared with the first nine months of 2013, reflecting higher sales for our Gypsum and Distribution segments, offset by lower sales for our Ceilings segment. Net sales increased 6% and 8% for our Gypsum and Distribution segments, respectively, and decreased 8% for our Ceilings segment. The higher levels of net sales for our Gypsum and Distribution segments reflected higher selling prices and, to a lesser extent, higher volumes. Lower net sales for our Ceilings segment primarily reflected the impact of contributing our subsidiaries in Asia-Pacific, India and Oman to UBBP on February 27, 2014. As a result, the first nine months of 2013 had nine months of net sales for those entities; however, the first nine months of 2014 only has two months of net sales for those entities. Excluding that impact, net sales for our Ceilings segment decreased 2%, primarily driven by lower volumes of ceiling tile and ceiling grid in the United States, partially offset by higher average selling prices.

GROSS PROFIT

Gross profit for the third quarter of 2014 increased $21 million, or 14%, compared with the third quarter of 2013. Gross profit as a percentage of net sales was 18.1% for the third quarter of 2014, compared with 16.8% for the third quarter of 2013. This gross profit improvement was primarily attributable to increased volume and higher selling prices for U.S. Gypsum’s SHEETROCK^® brand gypsum wallboard.

Gross profit for the first nine months of 2014 increased $64 million, or 15%, compared with the first nine months of 2013. Gross profit as a percentage of net sales was 17.8% for the first nine months of 2014, compared with 16.2% for the first nine months of 2013. This gross profit improvement was primarily attributable to increased volume and higher selling prices for U.S. Gypsum’s SHEETROCK^® brand gypsum wallboard, partially offset by lower sales volumes and higher per unit manufacturing costs for ceiling tile and grid in the United States, the effect of which was dampened partially by higher average selling prices.

SELLING AND ADMINISTRATIVE EXPENSES

Selling and administrative expenses totaled $76 million in the third quarter of 2014 compared to $80 million in the third quarter of 2013. The lower level of selling and administrative expenses in 2014 primarily reflected lower incentive compensation and the absence of expenses from USG International due to the contribution of our wholly-owned subsidiaries in the Asia-Pacific region and India and our consolidated joint ventures in Oman in the first quarter offset by an increase in information technology spend. As a percentage of net sales, selling and administrative expenses were 7.8% for the third quarter of 2014 compared to 8.6% for the third quarter of 2013.

Selling and administrative expenses totaled $230 million in the first nine months of 2014 compared to $229 million in the first nine months of 2013. The higher level of selling and administrative expenses in 2014 primarily reflected higher marketing expenses related to our new brand roll-out and information technology spend, partially offset by lower incentive compensation and the absence of expenses from USG International due to the contribution of our wholly-owned subsidiaries in the Asia-Pacific region and India and our consolidated joint ventures in Oman in the first quarter. As a percentage of net sales, selling and administrative expenses were 8.3% for the first nine months of 2014 compared to 8.6% for the first nine months of 2013.

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 lawsuit. 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.

INCOME FROM EQUITY METHOD INVESTMENTS

Income from equity method investments in the third quarter of 2014 was $12 million, an increase of $11 million from $1 million in the third quarter of 2013. The increase primarily reflects income of $12 million attributable to our share of the income of UBBP, our 50/50 joint venture with Boral.

Table of Contents

Income from equity method investments in the first nine months of 2014 was $20 million, an increase of $18 million from $2 million in the first nine months of 2013. The increase primarily reflects income of $19 million attributable to our share of the income of UBBP for the seven month period from the date of our investment in the joint venture to September 30, 2014,

INTEREST EXPENSE

Interest expense was $43 million in the third quarter of 2014, down $8 million, or 16%, from the third quarter of 2013. Lower interest expense primarily reflects a $12 million decrease due to the favorable impact of the conversion of $325 million and $75 million of our 10% convertible senior notes into common stock in December 2013 and April 2014, respectively, and the repayment of $59 million of our 2014 Notes. This decrease is partially offset by $5 million of additional interest expense related to our $350 million of 5.875% senior notes that were issued in October 2013.

Interest expense was $135 million in the first nine months of 2014, down $16 million, or 11%, from the first nine months of 2013. Lower interest expense primarily reflects a decrease of $29 million due to the favorable impact of the conversion of $325 million and $75 million of our 10% convertible senior notes into common stock in December 2013 and April 2014, respectively, and the repayment of $59 million of our 2014 Notes. This decrease is partially offset by $15 million of additional interest expense related to our $350 million of 5.875% senior notes that were issued in October 2013.

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

We had income tax expense of $2 million in the third quarter of 2014 unchanged from the third quarter of 2013. In both quarters, income tax expense reflects income taxes for certain foreign, state and local jurisdictions. Income tax expense was $7 million in the first nine months of 2014 compared to income tax expense of $1 million in the first nine months of 2013. Our effective tax rate for the first nine months of 2014 was 7.1% as we recorded expense of $7 million on pre-tax income of $99 million. Income tax expense in the first nine months of 2014 reflects income taxes for certain foreign, state and local jurisdictions, including approximately $1 million of withholding taxes on property contributed to UBBP. Since recording a valuation allowance against our federal and most of our state deferred tax assets in 2009, we do not record a tax expense or benefit from our income or losses in most domestic jurisdictions.

(c)	Results for the three and nine months ended September 30, 2013 and the first three months of 2014 have been recast to reflect our change in segments as described above under Overview.


(d)	Includes our mining operation in Little Narrows, Nova Scotia, Canada and our shipping company.

United States: Net sales in the third quarter of 2014 were $494 million, up $38 million, or 8%, compared with the third quarter of 2013. Net sales of SHEETROCK^® brand gypsum wallboard increased $20 million, or 9%, reflecting a 7% increase in average gypsum wallboard selling prices, which favorably affected sales by $15 million, and a 2% increase in gypsum wallboard shipments, which increased sales by $5 million. Net sales of products other than SHEETROCK^® brand gypsum wallboard, including freight, were $264 million in the third quarter of 2014, a 7% increase compared to the third quarter of 2013. Net sales of SHEETROCK^® brand joint compound increased $5 million due to a 4% increase in volume and a 1% increase in average selling price price. Net sales of DUROCK^®brand cement board increased $2 million driven by a 11% increase in volume partially offset by a 1% decrease in average selling price compared to the prior year period. Net sales of FIBEROCK^® brand gypsum fiber panels were essentially flat compared to the prior year period. Net sales of other products increased an aggregate of $7 million and outbound freight increased $4 million compared with the third quarter of 2013.

Our shipments of gypsum wallboard increased in the third quarter of 2014 compared to the third quarter of 2013 primarily due to improving market conditions, including increased demand from big box retailers that serve the residential repair and remodel market. We shipped 1.399 billion square feet of SHEETROCK^® brand gypsum wallboard in the third quarter of 2014, an increase of approximately 2% from 1.367 billion square feet in the third quarter of 2013. SHEETROCK^® Brand UltraLight Panels accounted for 63% of all of our wallboard shipments during the third quarter of 2014, compared to 58% in the second quarter of 2013 and 62% in the second quarter of 2014. We estimate that capacity utilization rates were approximately 68% for the industry and 58% for U.S. Gypsum during the third quarter of 2014.

U.S. Gypsum's average realized selling price for SHEETROCK^® brand gypsum wallboard was $164.80 per thousand square feet in the third quarter of 2014, up 7% from $154.04 in the third quarter of 2013 and down 2% from $167.31 in the second quarter of 2014. Excluding sales to customers outside of the United States, our average realized domestic selling price for SHEETROCK^® brand gypsum wallboard was $173.15 per thousand square feet in the third quarter of 2014, up 8% from $159.90 in the third quarter of 2013 and essentially flat compared to $174.32 in the second quarter of 2014. The calculation of domestic price was modified to exclude wallboard sales to all customers outside of the United States and not solely sales to

foreign subsidiaries, which was the definition used in the first quarter of this year. Accordingly, all historical domestic prices in this paragraph have been modified to be comparable with the new calculation.

Despite our realization of improvement in our average wallboard selling price, we could experience pressure on gypsum wallboard selling prices and our gross margins particularly if capacity utilization rates do not improve. In early 2014, as it did in 2013 and 2012, U.S. Gypsum implemented a price increase for wallboard with the new not to exceed price being set for the year. However, it is uncertain that we will be able to maintain the increase in our gypsum wallboard selling price. If we are unable to maintain our price increases, our net sales and operating profit may be materially impacted.

Operating loss of $2 million was recorded in the third quarter of 2014 compared with operating profit of $66 million in the third quarter of 2013. The $68 million decrease reflected a litigation settlement charge of $48 million due to the settlement in principal of the U.S. wallboard pricing class action lawsuit and impairment charges of $30 million primarily 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. This decrease was partially offset by gross profit improvements of $17 million for SHEETROCK^® brand gypsum wallboard, of which $15 million was due to a higher gross margin and $2 million was due to increased shipments. The higher wallboard gross margin was primarily attributable to higher selling prices and increased sales of higher margin SHEETROCK^® brand UltraLight Panel products, partially offset by higher per unit manufacturing costs. Gross profit for SHEETROCK^®brand joint compound increased $1 million from the prior year, while gross profit for DUROCK^® brand cement board and FIBEROCK^® brand gypsum fiber panels were essentially unchanged.

The decrease in operating profit also included $4 million of higher costs associated with information technology and $4 million of other costs and selling and administrative expenses.

Manufacturing costs per unit for U.S. Gypsum’s SHEETROCK^® brand gypsum wallboard were flat in the third quarter of 2014 compared with the third quarter of 2013 reflecting flat per unit costs for raw materials. Costs per unit decreased compared to the prior year quarter due to lower energy costs and lower fixed costs, reflecting the favorable impact of higher volumes. Offsetting the decrease is higher conversion costs.

Canada: Net sales in the third quarter of 2014 were $90 million unchanged from the third quarter of 2013. Excluding the unfavorable impact of currency translation of $4 million, net sales of SHEETROCK^®brand gypsum wallboard increased $5 million, primarily due to a 1% increase in average selling prices and a 10% increase in volume. Operating profit in the third quarter of 2014 was $5 million, unchanged from the third quarter of 2013.

Mexico / Latin America: Net sales for our gypsum businesses in Mexico and Latin America were $51 million in the third quarter of 2014, an increase of 4% from the third quarter of 2013. The higher net sales were primarily due to increases in net sales in Mexico of joint compound of $1 million and of drywall steel products of $1 million offset by a $1 million unfavorable impact of currency translation for Mexico. Operating profit was $5 million in the third quarter of 2014, unchanged from the third quarter of 2013.

Other: Other includes our mining operation in Little Narrows, Nova Scotia, Canada, and our shipping company. Total net sales for these operations for the third quarter of 2014 were $22 million, compared to $19 million in the third quarter of 2013. Operating profit was $4 million in the third quarter of 2014, up from an operating loss of $1 million in the third quarter of 2013. The increase in operating results primarily reflected higher operating profit for our shipping company, due to timing of shipments throughout the year, and, to a lesser extent, a increase in operating profit for our mining operation.

(a)	USG International’s net sales and operating profit for the nine months ended September 30, 2014 and the three and nine months ended September 30, 2013 include the results of our wholly-owned subsidiaries and consolidated joint ventures that were contributed to UBBP through February 27, 2014.


(b)	Results for the three and nine months ended September 30, 2013 and the first three months of 2014 have been recast to reflect our change in segments as described above under Overview.

United States: Net sales for our domestic ceilings business in the third quarter of 2014 were $125 million, an increase of $5 million, or 4%, from the third quarter of 2013. Net sales of ceiling grid were flat compared to the third quarter of 2013 reflecting the net impact of a 3% decrease in volume, which decreased sales by $1 million, offset by a 3% increase in selling prices, which favorably impacted sales by $1 million. Net sales of ceiling tile increased $4 million compared to the prior year period reflecting a 1% increase in volume, which increased sales by $1 million and a 4% increase in selling prices, which favorably impacted sales by $3 million.

Operating profit was $26 million for the third quarter of 2014, an increase of $6 million, or 30%, from the third quarter of 2013, which primarily reflected the absence of a $3 million environmental charge in the prior year period, lower selling and administration costs of $1 million and higher gross profit for ceiling tile and other products. Gross profit for ceiling grid was flat compared to the prior year period. Gross profit for ceiling tile increased $2 million primarily due to higher average selling prices.

USG International: As a result of our change in segments, as discussed above, 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 third quarter of 2013 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 $15 million for the third quarter of 2014 were flat compared to the third quarter of 2013. Operating profit of $2 million decreased $1 million compared to the third quarter of 2013. The decrease primarily reflects the impact of foreign currency translation, higher grid cost, due primarily to higher steel costs, and lower net sales for ceiling grid and specialty ceilings.

Mexico / Latin America: Net sales of $10 million for the third quarter of 2014 were flat compared to the third quarter of 2013. Operating profit was $2 million and unchanged from the third quarter of 2013.

(a)	Operating profit for the three and nine months of 2013 included a $1 million reversal of restructuring charges.

L&W Supply’s net sales in the third quarter of 2014 were $359 million, up $28 million or 8%, compared with the third quarter of 2013. Same store net sales for the third quarter of 2014 were up 8% compared with the third quarter of 2013. Net sales of gypsum wallboard increased $18 million, or 17%, reflecting 8% higher average gypsum wallboard selling prices, which favorably affected sales by $9 million, and a 8% increase in gypsum wallboard volume, which also favorably affected sales by $9 million. Net sales for joint treatment products increased $2 million, net sales for ceiling products increased $3 million and net sales for construction metal products increased $2 million. Net sales of all other products increased $1 million.

Operating profit was $4 million in the third quarter of 2014 compared with $3 million in the third quarter of 2013. The $1 million improvement in operating profit was attributable to increased gross profit of $3 million for gypsum wallboard, $1 million for ceilings, and $1 million for other products. The gross profit improvement for gypsum wallboard reflected the 8% increase in volume and a 5% increase in gross margin, which was partially offset by the unfavorable impact of rebates. Offsetting the increased gross profits are increased delivery expenses due to higher sales.

L&W Supply opened two new branches during the first nine months of 2014 and served its customers from 145 distribution branches in the United States as of September 30, 2014.

USG BORAL BUILDING PRODUCTS

USG Boral Building Products, or UBBP, is our 50/50 joint venture with Boral Limited and is accounted for as an equity method investment. Our investment consummated on February 27, 2014, and as a result, our share of seven months of equity income from UBBP is included in our accompanying consolidated statement of operations for the nine months ended September 30, 2014. See Note 2 to our consolidated financial statements included in this report. Income from equity method investments in our consolidated statement of operations for the three and nine months ended September 30, 2014, includes $12 million and $19 million, respectively, representing our share of the net income of UBBP. Our income from equity method investments for the nine months ended September 30, 2014 included approximately $2 million of costs representing our share of UBBP's restructuring costs discussed below.

The following is a discussion of UBBP's consolidated results for the three and nine months ended September 30, 2014.

In the third quarter of 2014, net sales for UBBP were $286 million, plasterboard shipments were 1.14 billion square feet, operating profit was $31 million and net income attributable to UBBP was $24 million.

Net sales in South Korea, China, Thailand and Indonesia represented approximately 83% of Asia's net sales and plasterboard revenue accounted for approximately 70% of Asia's net sales. Results for UBBP included $7 million ($5 million, net of tax) of restructuring costs incurred in the second quarter of 2014.

The operating loss for Corporate decreased to $23 million in the third quarter of 2014 compared with $25 million in the third quarter of 2013 primarily due to lower expenses related to incentive compensation offset by increased spend on information technology.

Liquidity and Capital Resources

As of September 30, 2014, we had $340 million of cash and cash equivalents and marketable securities compared with $952 million as of December 31, 2013. The primary driver of the decrease was a cash outflow of $558 million for our investment in UBBP. See discussion below under Cash Flows for a further explanation of this cash outflow and the other drivers of the decrease in cash and cash equivalents. Our total liquidity as of September 30, 2014 was $686 million (including $346 million of borrowing availability under our credit facilities in the United States and Canada) compared to $1.266 billion as of December 31, 2013 (including $314 million of borrowing availability under our credit facilities in the United States, Canada and Oman). The decrease in total liquidity was primarily attributable to our $558 million cash outflow for our investment in UBBP.

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, industrial revenue bonds, and outstanding borrowings under our ship mortgage facility and, as of December 31, 2013, convertible senior notes and borrowings under our Oman joint ventures' credit facilities, amounted to $2.210 billion ($2.212 billion in aggregate principal amount less $2 million of unamortized original issue discount) as of September 30, 2014 and $2.355 billion ($2.359 billion in aggregate principal amount less $4 million of unamortized original issue discount) as of December 31, 2013. As of September 30, 2014 and during the nine months then ended, there were no borrowings under our U.S. revolving credit facility and, during the nine months then ended, an immaterial amount borrowed on our Canadian revolving credit facility and no borrowings outstanding as of September 30, 2014.

As of December 31, 2013, there was $11 million of borrowings outstanding under the credit facilities of our joint ventures in Oman. An additional $3 million was borrowed under this facility during the two months ended February 27, 2014, at which time our joint ventures in Oman, along with the corresponding credit facilities, were contributed to UBBP. See Note 2 to our consolidated financial statements for additional information about our investment in UBBP and Note 8 for additional information about our debt.

Our U.S. credit facility is guaranteed by our significant domestic subsidiaries and secured by their and USG’s trade receivables and inventory. It matures in December 2015 and allows for revolving loans and letters of credit (up to $250 million) in an aggregate principal amount not to exceed the lesser of (a) $400 million or (b) a borrowing base determined by reference to the trade receivables and inventory of USG and its significant domestic subsidiaries. The maximum allowable borrowings may be increased at our request with the agreement of the lenders providing increased or new lending commitments, provided that the maximum allowable borrowings after giving effect to the increase may not exceed $600 million. Availability under the credit facility will increase or decrease depending on changes to the borrowing base over time.

Our U.S. credit facility contains a single financial covenant that would require us to maintain a minimum fixed charge coverage ratio of 1.1-to-1.0 if and for so long as the excess of the borrowing base over the outstanding borrowings under the credit agreement is less than the greater of (a) $40 million and (b) 15% of the lesser of (i) the aggregate revolving commitments at such time and (ii) the borrowing base at such time. As of September 30, 2014, our fixed charge coverage ratio was 1.14-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 as of September 30, 2014 were approximately $311 million.

On April 17, 2014, we entered into Amendment No. 1 (the “Amendment”) to our U.S. credit facility. The Amendment, among other things, (i) deleted the provisions providing for an early maturity date in the event we either (x) have not repaid or provided for the repayment of our outstanding 9.75% senior notes due 2014 (the “2014 Notes”) by May 2, 2014 or (y) did not have at least $500 million in liquidity from May 2, 2014 until the repayment of the 2014 Notes, and (ii) revised the definition of borrowing base to add an additional reserve against the borrowing base in the amount of the unpaid principal balance of the 2014 Notes outstanding from time to time. We made a final principal and interest payment of $62 million for the 2014 Notes with cash on hand on August 1, 2014.

The maximum amount available for borrowing under CGC’s credit facility is Can. $40 million, all of which is available for borrowing. The U.S. dollar equivalent of borrowings available under CGC’s credit facility as of September 30, 2014 was

Table of Contents

$35 million. Also on October 22, 2014, in connection with the amendment and restatement of our credit facility, we terminated our Canadian credit facility described below.

On October 22, 2014, we amended and restated our credit facility in order to, among other things, join CGC as a party and to increase the maximum borrowing limit under the credit agreement from $400 million to $450 million (including a $50 million borrowing sublimit for CGC). As amended and restated, 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 as follows. The credit agreement contains two borrowing bases, one determined by reference to the trade receivables and inventory of USG and the U.S. guarantors (the “U.S. Borrowing Base”) and one determined by reference to the trade receivables and inventory of CGC and certain Canadian subsidiaries (the “Canadian Borrowing Base”). Pursuant to the credit agreement, the maximum principal amount of revolving loans and letters of credit that may be borrowed by and/or be issued in favor of USG at any time (the total amount outstanding at any time, the “U.S. Revolving Exposure”) may not exceed the lesser of (1) $450 million, as such mount may be increased in accordance with the credit facility, the "Revolving Commitment" (less the sum of the outstanding principal balance of the revolving loans and letters of credit made and/or issued to or for the account of CGC at such time, such sum being the “Canadian Revolving Exposure”) and (2) the excess of (a) the U.S. Borrowing Base minus (b) the amount, if any, by which of the Canadian Revolving Exposure exceeds the Canadian Borrowing Base at such time. The maximum principal amount of revolving loans and letters of credit that may be borrowed by and/or be issued in favor of CGC at any time may not exceed the lesser of (1) $50 million and (2) the sum of the Canadian Borrowing Base, plus the U.S.Borrowing Base, minus the U.S. Revolving Exposure at such time. At no time may the sum of the U.s. Revolving Exposure and the Canadian Revolving Exposure exceed the U.S. REvolving Exposure.

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. We would be required to continue to comply with such financial covenant until the availability under the credit agreement exceeds such minimum threshold for 30 consecutive calendar days thereafter.

In March 2014, we issued a notice of redemption to redeem the remaining $75 million in aggregate principal amount of outstanding 10% convertible senior notes due 2018. The notes called for redemption could either be (1) redeemed at a stated redemption price or (2) converted into shares of our common stock. The holders of all $75 million in notes called for redemption elected to convert their notes into shares of USG’s common stock. Accordingly, as of April 15, 2014, we issued an additional 6,578,946 shares of our common stock in connection with the conversion of the notes.

Our undistributed foreign earnings as of September 30, 2014 are considered permanently reinvested. The amount of cash and cash equivalents held by our foreign subsidiaries was $89 million as of September 30, 2014. 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)	2014			2013
Net cash provided by (used for):
Operating activities	$	80		$	12
Investing activities	(585		)	(102		)
Financing activities	(62		)	1
Discontinued operations	(1		)	(1		)
Effect of exchange rate changes on cash	(2		)	(4		)
Net decrease in cash and cash equivalents	$	(570	)	$	(94	)

Operating Activities: The change in net cash provided by operating activities for the first nine months of 2014 compared to the net cash provided by operating activities in the first nine months of 2013 primarily reflected improved operating results and a reduction in the use of working capital in the nine months ended September 30, 2014 compared to the prior year period.

As of September 30, 2014, working capital (current assets less current liabilities) amounted to $661 million, and the ratio of current assets to current liabilities was 2.28-to-1. As of December 31, 2013, working capital amounted to $1.132 billion, and the ratio of current assets to current liabilities was 2.99-to-1.

Investing Activities: Net cash used in investing activities during the first nine months of 2014 was $585 million compared to $102 million during the first nine months of 2013. The increased use of cash was mostly driven by a cash outflow in February 2014 of $558 million for our investment in UBBP, consisting of a $500 million base purchase price, $13 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. In October 2014, we paid an additional $2 million to Boral in conjunction with customary post-closing adjustments. Capital expenditures amounted to $88 million in the first nine months of 2014 compared with $72 million in the first nine months of 2013.

Financing Activities: Net cash used in financing activities for the first nine months of 2014 was $62 million compared to net cash provided by financing activities of $1 million in the first nine months of 2013. The increased use of cash primarily reflected our payment of $59 million for our 9.75% senior notes due 2014.

Approved capital expenditures for the replacement, modernization and expansion of operations totaled $109 million as of September 30, 2014 compared with $307 million as of December 31, 2013.

DEFINED BENEFIT PLANS

During the first quarter of 2014, the U.S. Society of Actuaries released for public comment two draft proposals regarding the current rate of mortality observed in the portion of the U.S. population covered by corporate pension plans. These proposals, which generally indicate substantial life expectancy improvements, represent a change from the mortality assumptions that we currently use for purposes of financial reporting and that we are required to use for regulatory funding purposes.

Based on the proposals, it is likely we would revise the mortality assumptions used in determining our defined benefit pension and postretirement benefit obligations as of December 31, 2014, which would also have a related impact on our annual defined benefit pension and postretirement benefit expense in future years. Assuming no changes to applicable funding regulations and other assumptions, we expect that the new mortality assumptions, when fully implemented for accounting and plan funding, will likely result in an increase of approximately $80 to $90 million in pension and postretirement liabilities and thereafter approximately $13 to $14 million in annual pension and postretirement expense, and may also result in higher

Table of Contents

pension funding requirements in future periods depending upon the funded status of our defined benefit pension plans. Final updates to the mortality assumptions are expected to be issued by the end of 2014, and the earliest a new mortality table is expected to be required for determining minimum ERISA funding requirements is January 1, 2016.

LIQUIDITY OUTLOOK

In the first nine months of 2014, our investing cash outflows included $558 million for our investment in UBBP and $88 million of capital expenditures, of which $6 million was spent by our Oman consolidated joint ventures through February 27, 2014. Due to current market conditions, we have lowered our annual plan for capital expenditures by approximately $15 million. In total for 2014, we plan to spend in the range of $130 to $135 million, which includes the $6 million of capital spending made by our Oman consolidated subsidiaries prior to their contribution to UBBP. We expect to fund these expenditures with cash from operations or cash on hand, and, if determined to be appropriate and they are available, borrowings under our revolving credit facilities. Interest payments, based on our current level of outstanding debt, are expected to decrease to approximately $175 million in 2014 compared with $195 million in 2013 primarily due to the conversion of $325 million and $75 million of our 10% convertible senior notes in December 2013 and April 2014, respectively, and the repayment of our 9.75% senior notes in August 2014, partially offset by interest on the $350 million of 5.875% senior notes issued in October 2013.

From February 27, 2014 through September 30, 2014, 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. Through September 30, 2014, no dividends have been declared or paid by UBBP. The amount and timing of any distribution is currently unknown.

In the third quarter of 2014, we recorded an accrual related to the settlement in principal of the U.S. wallboard pricing class action lawsuit. We expect to pay the settlement with cash from operations or cash on hand within the next twelve months.

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, 2014, we had federal NOL carryforwards of approximately $1.993 billion that are available to offset future federal taxable income and will expire in the years 2026 through 2033. In addition, as of that date, we had federal AMT credit carryforwards of approximately $45 million that are available to reduce future regular federal income taxes over an indefinite period.

For the nine months ended September 30, 2014, we decreased our valuation allowance by $34 million which resulted in a deferred tax asset valuation allowance of $961 million as of September 30, 2014. 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. In future periods, the valuation allowance can be reversed based on sufficient evidence indicating that it is more likely than not that a portion of our deferred tax assets will be realized.

See Note 16 to the consolidated financial statements for additional information regarding income tax matters.

Recently Issued Accounting Pronouncements

In April 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU 2014-08"), "Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity," which includes amendments that change the requirements for reporting discontinued operations and require additional disclosures about discontinued operations. Under the new guidance, only disposals representing a strategic shift in operations - that is, a major effect on the organization's operations and financial results - should be presented as discontinued operations. Examples include a disposal of a major geographic area, a major line of business, or a major equity method investment. Additionally, ASU 2014-08 requires expanded disclosures about discontinued operations that will provide financial statement users with more information about the assets, liabilities, income, and expenses of discontinued operations. This update is effective for us in the first quarter of 2015. We do not expect that the adoption of ASU 2014-08 will have a significant impact to our consolidated financial statements or disclosures.

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. In October 2014, we entered into a settlement agreement in principle with the attorneys representing the direct and indirect purchaser plaintiffs in the U.S. wallboard pricing lawsuits naming USG Corporation and United States Gypsum Company. Pursuant to the settlement, which is subject to court approval, USG will pay a total of $48 million to resolve the U.S. direct and indirect purchaser cases.Accordingly, we have recorded a $48 million charge in the third quarter of 2014 related to this settlement. If we are unable to settle the U.S. litigation under the terms currently contemplated, or at all, there can be no assurance that the outcome of these lawsuits will not have a material effect on our business, financial condition, operating results or cash flows. The settlement does 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.

We have also 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.

We believe that we have appropriately accrued for our potential liability in connection with these matters, 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. However, we continue to review these accruals as additional information becomes available and revise them as appropriate. We do not currently expect these matters to have a material effect upon our results of operations, financial position or cash flows. See Note 17 to the consolidated financial statements for additional information regarding litigation matters.

Critical Accounting Policies

The preparation of our financial statements requires us to make estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses during the periods presented. Our Annual Report on Form 10-K for the fiscal year ended December 31, 2013, which we filed with the Securities and Exchange Commission on March 3, 2014, includes a summary of the critical accounting policies we believe are the most important to aid in understanding our financial results. There have been no changes to those critical accounting policies that have had a material impact on our reported amounts of assets, liabilities, revenues or expenses during the first nine months of 2014.

Forward-Looking Statements

This report contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 related to management’s expectations about future conditions. Actual business, market or other conditions may differ materially from management’s expectations and, accordingly, may affect our sales and profitability or other results and liquidity. Actual results may differ materially due to various other factors, including:


•	economic conditions, such as the levels of new home and other construction activity, employment levels, the availability of mortgage, construction and other financing, mortgage and other interest rates, housing affordability and supply, the levels of foreclosures and home resales, currency exchange rates and consumer confidence;


•	capital markets conditions and the availability of borrowings under our credit agreement or other financings;


•	our substantial indebtedness and our ability to incur substantial additional indebtedness;


•	competitive conditions, such as price, service and product competition;


•	shortages in raw materials;


•	changes in raw material and energy costs;


•	volatility in the assumptions used to determine the funded status of our pension plans;


•	the loss of one or more major customers and our customers’ ability to meet their financial obligations to us;


•	capacity utilization rates for us and the industry;


•	our ability to expand into new geographic markets and the stability of such markets;


•	our ability to successfully operate USG Boral Building Products, including risks that our joint venture partner, Boral, may not fulfill its obligations as an investor or may take actions that are inconsistent with our objectives;


•	our ability to protect our intellectual property and other proprietary rights;


•	changes in laws or regulations, including environmental and safety regulations;


•	the satisfactory performance of certain business functions by third party service providers;


•	our ability to achieve anticipated savings from cost reduction programs;


•	the outcome in contested litigation matters;


•	the effects of acts of terrorism or war upon domestic and international economies and financial markets; and

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 two 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 2014 and 2015 is hedged as well as a portion of our anticipated purchases of natural gas for 2016. The aggregate notional amount of these hedge contracts in place as of September 30, 2014 was 22 million mmBTUs. 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 $3 million as of September 30, 2014. 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, 2014 was $9 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, 2014 was $7 million. This analysis does not consider the underlying exposure.

INTEREST RATE RISK

As of September 30, 2014, most of our outstanding debt was fixed-rate debt. A sensitivity analysis was prepared to estimate the potential change in interest expense assuming a hypothetical 100-basis-point increase in interest rates. Based on the results of this analysis, which may differ from actual results, the potential change in interest expense would be immaterial.

A sensitivity analysis was also prepared to estimate the potential change in fair value of our marketable securities portfolio assuming a hypothetical 100-basis-point increase in interest rates. Based on the results of this analysis, which may differ from actual results, the potential change in fair value of our marketable securities as of September 30, 2014 would be $1 million.

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, 2014 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

See Part I, Item 1, Note 17 to the consolidated financial statements for additional information regarding legal proceedings.

ITEM 1A. RISK FACTORS

There is no material change in the information reported under "Part I-Item 1A-Risk Factors" contained in our Annual Report on Form 10-K for the fiscal year ended December 31, 2013 with the exception of the risk factor set forth in "Item 1.A . Risk Factors" in our Quarterly Report on Form 10-Q for the quarter ended June 30, 2014 and the following:

An Epidemic of the Ebola virus disease is ongoing in West Africa and may adversely affect our business operations and financial condition.

An epidemic of the Ebola virus disease is ongoing in Sierra Leone and other parts of West Africa. More than 4,000 deaths have been reported by the World Health Organization (“WHO”) in West Africa, and the WHO has declared it a global health emergency. It is impossible to predict the effect and potential spread of the Ebola virus in Sierra Leone or surrounding countries.

Gypsum Transportation Limited, or GTL, our wholly owned subsidiary, owns two self-unloading ocean vessels. In 2013, GTL completed the second year of a five-year contract of affreightment to transship iron ore for a third party in and around Sierra Leone.

Should the Ebola virus continue to spread or not be satisfactorily contained in West Africa, GTL’s operations could be interrupted or cease. In particular, the epidemic of the Ebola virus disease may lead to the illness of the staff of GTL or the third party currently using the vessels, which could disrupt the operations of the vessels, or to public health measures, which may prevent our vessels from calling on ports or discharging cargo in the affected areas or in other locations after having visited the affected areas. Any interruption in our ability to operate our vessels, or fulfill the contract of affreightment to which GTL is a party, could have a material adverse effect on our business, financial condition, operating results and cash flows.

ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

None.
