Accounting Policies [Abstract] | ' | |
Significant Accounting Policies | ' | |
Significant Accounting Policies | ||
Nature of Operations | ||
USG, through its subsidiaries, is 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. Our products also are distributed through building materials dealers, home improvement centers and other retailers, specialty wallboard distributors, and contractors. | ||
Segments | ||
Our operations are organized into three reportable segments: North American Gypsum, Worldwide Ceilings and Building Products Distribution. Our determination of the reportable segments was made on the basis of our strategic business units and the commonalities among the products within each segment, and corresponds to the manner in which management reviews and evaluates operating performance. Certain similar operating segments that meet applicable aggregation criteria have been combined. | ||
North American Gypsum manufactures SHEETROCK® brand gypsum wallboard and related products. Worldwide Ceilings manufactures ceiling tile in the United States and ceiling grid in the United States, Canada and the Asia-Pacific region. Building Products Distribution distributes gypsum wallboard, drywall metal, ceilings products, joint compound and other building products throughout the United States. | ||
Consolidation and Presentation | ||
Our consolidated financial statements include the accounts of USG Corporation, its majority-owned subsidiaries and variable interest entities. Entities in which we have more than a 20% but not more than 50% ownership interest are accounted for using the equity method of accounting and are not material to our consolidated operations. All intercompany balances and transactions are eliminated in consolidation. On our consolidated statements of cash flows for the years ended December 31, 2012 and 2011, a portion of the amounts previously included within "(Decrease) increase in other liabilities" have been reclassified to "(Decrease) increase in pension and other postretirement benefits" to conform to the current year presentation, and amounts previously included in "Receivables" have been reclassified to "Provision for Bad Debt." | ||
Use of Estimates | ||
The preparation of our consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets, liabilities, revenues and expenses. Actual results could differ from these estimates. | ||
Revenue Recognition | ||
With the exception of our Building Products Distribution segment, we recognize revenue upon the shipment of products to customers, which is when title and risk of loss are transferred to customers, and our products are generally shipped free on board, commonly called FOB, shipping point. For Building Products Distribution, revenue is recognized and title and risk of loss are transferred when customers receive products, either through delivery by company trucks or customer pickup. We record provisions for discounts to customers based on the terms of sale in the same period in which the related sales are recorded. We record estimated reductions to revenue for customer programs and incentive offerings, including promotions and other volume-based incentives, in the period in which the sale occurs. | ||
Shipping and Handling Costs | ||
Shipping and handling costs are included in cost of products sold. | ||
Advertising | ||
Advertising expenses consist of media advertising and related production costs and sponsorships. We charge advertising expenses to earnings as incurred. These expenses amounted to $22 million for the year ended December 31, 2013 and $15 million for each of the years ended December 31, 2012 and 2011. | ||
Research and Development | ||
We charge research and development expenditures to earnings as incurred. These expenditures amounted to $21 million, $18 million and $13 million for the years ended December 31, 2013, 2012 and 2011, respectively. | ||
Income Taxes | ||
We record income tax expense (benefit) under the asset and liability method. Under this method, deferred tax assets and liabilities are recognized based on the future tax consequences to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and attributable to net operating loss, or NOL, and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply in the years in which the temporary differences are expected to be recovered or paid. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in earnings in the period when the change is enacted. Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not that a tax benefit will not be realized. | ||
Inventory Valuation | ||
All of our inventories are stated at the lower of cost or market. Virtually all of our inventories are valued under the average cost method with the remainder valued under the first-in, first-out cost method. Inventories include materials, labor and applicable factory overhead costs. Depreciation associated with manufacturing assets is excluded from inventory cost, but is included in cost of products sold. | ||
Earnings (Loss) per Share | ||
Basic earnings (loss) per share is based on the weighted average number of common shares outstanding. Diluted earnings per share is based on the weighted average number of common shares outstanding plus the dilutive effect, if any, of restricted stock units, or RSUs, and performance shares, the potential exercise of outstanding stock options and the potential conversion of our 10% convertible senior notes. | ||
Cash and Cash Equivalents | ||
Cash and cash equivalents include highly liquid investments, primarily money market funds, with maturities of three months or less at the time of purchase. | ||
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), or AOCI. If it is deemed that marketable securities have unrealized losses that are other than temporary, these losses will be recorded in earnings immediately. Situations in which losses may be considered other than temporary include when we have decided to sell a security or when it is more likely than not that we will be required to sell the security before we recover its amortized cost basis. | ||
Receivables | ||
We include trade receivables in receivables on our consolidated balance sheets. Trade receivables are recorded at net realizable value, which includes allowances for cash discounts and doubtful accounts, and are reflected net of customer incentives. We review the collectability of trade receivables on an ongoing basis. We reserve for trade receivables determined to be uncollectible. This determination is based on the delinquency of the account, the financial condition of the customer and our collection experience. | ||
We include short-term financing receivables in receivables and long-term financing receivables in other assets on our consolidated balance sheets. Financing receivables are recorded at net realizable value which includes an allowance for credit losses. We review the collectability of financing receivables on an ongoing basis. We reserve for financing receivables determined to be uncollectible. This determination is based on the delinquency of the account and the financial condition of the other party. As of December 31, 2013, the allowance for credit losses was immaterial. | ||
Property, Plant and Equipment | ||
Property, plant and equipment is recorded at cost. We record depreciation of property, plant and equipment on a straight-line basis over the expected useful lives of the assets. We have determined estimated useful lives to be 50 years for buildings and improvements, a range of 10 to 25 years for machinery and equipment, and 5 years for computer software and systems development costs. Leasehold improvements are capitalized and amortized over the shorter of the remaining lease term or remaining economic useful life. We capitalize interest during the active construction period of major capital projects. Capitalized interest is added to the cost of the underlying assets and is depreciated over the useful lives of those assets. There was $3 million of interest capitalized in 2013, and no interest was capitalized in 2012 or 2011. Facility start-up costs that cannot be capitalized are expensed as incurred and recorded in cost of products sold. We compute depletion on a basis calculated to spread the cost of gypsum and other applicable resources over the estimated quantities of material recoverable. We review property, plant and equipment for impairment when indicators of a potential impairment are present by comparing the carrying values of the assets with their estimated future undiscounted cash flows. If we determine an impairment exists, the asset is written down to estimated fair value. As of December 31, 2013, we had $1 million of net property, plant and equipment included in other current assets on the consolidated balance sheet classified as “assets held for sale.” These assets are included in our North American Gypsum reportable segment. As of December 31, 2012, there were no assets classified as held for sale on our consolidated balance sheet. In 2012, we recognized a gain on the sale of approximately $4 million of assets which were previously classified as assets held for sale as of December 31, 2011. | ||
Intangible Assets | ||
We perform impairment tests for intangible assets with indefinite useful lives as of October 31 of each year, or more frequently if events occur or circumstances change that would more likely than not reduce the fair value of an intangible asset below its carrying value. The impairment test consists of a comparison of the fair value of the asset with its carrying amount. If the carrying amount of an intangible asset exceeds its fair value, an impairment loss is recognized in an amount equal to that excess. Intangible assets determined to have indefinite useful lives, primarily comprised of trade names, are not amortized. An income approach is used for valuing trade names. Assumptions used in the income approach include projected revenues and assumed royalty, long-term growth and discount rates. We perform impairment tests on definite lived intangible assets, such as customer relationships, upon identification of events or circumstances that may indicate the carrying amount of the assets might be unrecoverable by comparing their undiscounted cash flows with their carrying value. If we determine impairment exists, the assets are written down to estimated fair value. | ||
Share-Based Compensation | ||
We award share-based compensation to employees in the form of stock options, restricted stock units, market share units, and performance shares and to directors in the form of shares of our common stock. All grants under share-based payment programs are accounted for at fair value at the date of grant. We recognize expense on all share-based awards to employees expected to vest over the service period, which is the shorter of the period until the employees’ retirement eligibility dates or the service period of the award. | ||
Derivative Instruments | ||
We use derivative instruments to manage selected 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. All derivative instruments must be recorded on the balance sheet at fair value. For derivatives designated as fair value hedges, the changes in the fair values of both the derivative instrument and the hedged item are recognized in earnings in the current period. For derivatives designated as cash flow hedges, the effective portion of changes in the fair value of the derivative is recorded to AOCI, and is reclassified to earnings when the underlying forecasted transaction affects earnings. The ineffective portion of changes in the fair value of the derivative is reported in cost of products sold in the current period. We periodically reassess the probability of the underlying forecasted transaction occurring. For derivatives designated as net investment hedges, we record changes in fair value to AOCI. For derivatives not designated as hedging instruments, all changes in fair value are recorded to earnings in the current period. | ||
Currently, we are using swap and option contracts to hedge a significant portion of our anticipated purchases of natural gas to be used in our manufacturing operations. Generally, we hedge the cost of a majority of our anticipated purchases of natural gas over the next 12 months. However, we review our positions regularly and make adjustments as market conditions warrant. The majority of contracts currently in place are designated as cash flow hedges, and the remainder are not designated as hedging instruments. | ||
We have operations in a number of countries and use forward contracts from time-to-time to hedge the risk of changes in cash flows resulting from selected forecasted intercompany and third-party sales or purchases, as well as intercompany loans, denominated in non-U.S. currencies, or to hedge the risk of selected changes in our net investment in foreign subsidiaries. These contracts are designated as either cash flow hedges or net investment hedges or are not designated as hedging instruments. | ||
Foreign Currency Translation | ||
We translate foreign-currency-denominated assets and liabilities into U.S. dollars at the exchange rates existing as of the respective balance sheet dates. We translate income and expense items at the average exchange rates during the respective periods. We record translation adjustments resulting from fluctuations in exchange rates to AOCI on our consolidated balance sheets. We record transaction gains and losses to earnings. The total transaction loss was $4 million in 2013, $0 in 2012 and $4 million in 2011. | ||
Fair Value Measurements | ||
Certain assets and liabilities are required to be recorded at fair value. The estimated fair values of those assets and liabilities have been determined using market information and valuation methodologies. Changes in assumptions or estimation methods could affect the fair value estimates. However, we do not believe any such changes would have a material impact on our financial condition, results of operations or cash flows. There are three levels of inputs that may be used to measure fair value: | ||
• | Level 1 – Quoted prices for identical assets and liabilities in active markets; | |
• | Level 2 – 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; and | |
• | Level 3 – Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable. | |
Certain assets and liabilities are measured at fair value on a nonrecurring basis rather than on an ongoing basis, but are subject to fair value adjustments in certain circumstances, such as when there is evidence of impairment or when a new liability is being established that requires fair value measurement. |

In February 2013, the Financial Accounting Standards Board, or FASB, issued "Comprehensive Income: Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income," which requires entities to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, entities are required to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts that are not required under U.S. GAAP to be reclassified in their entirety to net income, entities are required to cross-reference to other disclosures required under U.S. GAAP that provide additional detail on these amounts. This standard is effective prospectively for reporting periods beginning after December 15, 2012. We adopted this standard during the first quarter of 2013 and have included the required disclosure in Note 11. | |
In December 2011 and February 2013, the FASB issued an amendment to the Balance Sheet topic of the Accounting Standards Codification, or ASC, which requires entities to disclose both gross and net information about both derivatives and transactions eligible for offset in the statement of financial position and instruments and transactions subject to an agreement similar to a master netting agreement. The objective of the disclosure is to facilitate comparison between those entities that prepare their financial statements on the basis of U.S. GAAP and those entities that prepare their financial statements on the basis of International Financial Reporting Standards. This standard is effective for fiscal years, and interim periods within those years, beginning on or after January 1, 2013. Retrospective presentation for all comparative periods presented is required. Accordingly, we adopted this amendment during the first quarter of 2013 and have included the required disclosure in Note 7. |

5.875% Senior Notes due 2021 - On October 31, 2013, we issued $350 million aggregate principal amount of 5.875% senior notes due 2021. The notes bear interest at a rate of 5.875% per year and we will pay interest on May 1 and November 1 of each year, beginning May 1, 2014. The notes mature on November 1, 2021. See below for further description of these notes under Senior Notes. | ||||||||||||||||||||||||
2012 Repurchase of 9.75% Senior Notes and Issuance of 7.875% Senior Notes - On April 12, 2012, we completed a cash tender offer pursuant to which we repurchased approximately $118 million of our 9.75% senior notes due in 2014 for aggregate consideration, including tender offer premium and accrued and unpaid interest, of approximately $136 million. Subsequent to the completion of the cash tender offer, we repurchased an additional $123 million of these notes in privately negotiated transactions, for aggregate consideration, including premiums and accrued and unpaid interest, of $145 million. As a result of the repurchases, in the second quarter of 2012, we recorded a loss on early extinguishment of debt of $41 million, including premiums, the write-off of unamortized debt discount and deferred financing fees. As of December 31, 2013 and December 31, 2012, $59 million of these notes remain outstanding, net of an immaterial amount of unamortized debt discount. Also on April 12, 2012, we issued $250 million of 7.875% senior notes due March 30, 2020. The net proceeds from the issuance of these notes and cash on hand were used to fund the repurchases of the 9.75% senior notes and all related costs and expenses. We deferred $5 million of financing costs which we are amortizing to interest expense over the term of the notes. As of December 31, 2013, these notes are recorded on the consolidated balance sheet at $249 million, net of unamortized debt discount of $1 million. | ||||||||||||||||||||||||
Senior Notes | ||||||||||||||||||||||||
All of the senior notes, including the senior notes issued in October 2013, are senior unsecured obligations and rank equally with all of our other existing and future unsecured senior indebtedness. The indentures governing the notes contain events of default, covenants and restrictions that are customary for similar transactions, including a limitation on our ability and the ability of certain of our subsidiaries to create or incur secured indebtedness. | ||||||||||||||||||||||||
Our obligations under the 5.875%, 7.875%, 8.375% and 9.75% senior notes are guaranteed on a senior unsecured basis by certain of our domestic subsidiaries. | ||||||||||||||||||||||||
The interest rate payable on the 7.75% senior notes is subject to adjustment from time to time by up to 2% in the aggregate if the debt ratings assigned to the notes are upgraded or thereafter downgraded. At our current credit ratings, the interest rate on these notes is at the maximum level of 9.75%. | ||||||||||||||||||||||||
The 5.875%, 7.875%, 8.375% and 9.75% senior notes contain a provision requiring us to offer to purchase those notes at a premium of 101% of their principal amount (plus accrued and unpaid interest) in the event of a change in control. The 7.75% and 6.3% senior notes contain a provision requiring us to offer to purchase those notes at a premium of 101% of their principal amount (plus accrued and unpaid interest) in the event of a change in control and a related downgrade of the rating on the notes to below investment grade by both Moody’s Investors Service and Standard & Poor’s Financial Services LLC. | ||||||||||||||||||||||||
The 6.3%, 7.75% and 9.75% senior notes contain a provision that allows us to redeem the notes in whole at any time, or in part from time to time, at our option, at a redemption price equal to the greater of (1) 100% of the principal amount of the notes being redeemed and (2) the sum of the present value of the remaining scheduled payments of principal and interest on the notes being redeemed discounted to the redemption date on a semi-annual basis at the applicable U.S. Treasury rate plus a spread (as outlined in the respective indentures), plus, in each case, any accrued and unpaid interest on the principal amount being redeemed to the redemption date. | ||||||||||||||||||||||||
The 8.375% senior notes contain a similar provision that allows us to redeem those notes, in whole or in part from time to time, at our option, on or after October 15, 2014 at stated redemption prices, plus any accrued and unpaid interest to the redemption date. In addition, we may redeem the notes in whole or in part from time to time, at our option, prior to October 15, 2014 at a redemption price equal to 100% of the principal amount of the notes redeemed plus a premium (as specified in the supplemental indenture with respect to those notes), plus any accrued and unpaid interest. | ||||||||||||||||||||||||
The 7.875% senior notes contain a similar provision that allows us to redeem those notes, in whole or in part from time to time, at our option, on or after March 30, 2016 at stated redemption prices, plus any accrued and unpaid interest to the redemption date. In addition, we may redeem the notes in whole or in part from time to time, at our option, prior to March 30, 2016 at a redemption price equal to 100% of the principal amount of the notes being redeemed plus a premium (as specified in the supplemental indenture with respect to those notes), plus any accrued and unpaid interest. | ||||||||||||||||||||||||
The 5.875% senior notes contain a similar provision that allows us to redeem those notes, in whole or in part from time to time, at our option, on or after November 1, 2016 at stated redemption prices, plus any accrued and unpaid interest to the redemption date. In addition, we may redeem the notes in whole or in part from time to time, at our option, prior to November 1, 2016 at a redemption price equal to 100% of the principal amount of the notes redeemed plus a premium (as specified in the supplemental indenture with respect to those notes), plus any accrued and unpaid interest. | ||||||||||||||||||||||||
Convertible Senior Notes and December 2013 Conversion | ||||||||||||||||||||||||
As of December 31, 2012, we had $400 million aggregate principal amount of 10% convertible senior notes due 2018 that were recorded on the consolidated balance sheet at $385 million, net of debt discount of $15 million. The notes bear cash interest at the rate of 10% per year until maturity, redemption or conversion. These notes are initially convertible into 87.7193 shares of our common stock per $1,000 principal amount of notes which is equivalent to an initial conversion price of $11.40 per share, or a total of 35.1 million shares. These notes contain anti-dilution provisions that are customary for convertible notes issued in transactions similar to that in which the notes were issued. These notes mature on December 1, 2018 and were callable beginning December 1, 2013, after which we could elect to redeem all or part of the notes at stated redemption prices, plus accrued and unpaid interest. | ||||||||||||||||||||||||
In November 2013, we issued a notice of redemption to redeem $325 million in aggregate principal amount of the outstanding notes at the stated redemption price of 105%. In December 2013, the holders of all $325 million in notes called for redemption elected to convert their notes into shares of our common stock. Accordingly, we issued an additional 28,508,768 shares of our common stock in connection with the conversion of the notes. As of December 31, 2013, the amount recorded on our consolidated balance sheet for the outstanding convertible senior notes is $72 million, net of unamortized debt discount of $3 million. | ||||||||||||||||||||||||
Affiliates of Berkshire Hathaway, Inc., who own approximately 28% of our outstanding shares of common stock as of December 31, 2013, held $300 million of these notes, prior to the December 2013 conversion, which are reflected on our consolidated balance sheets, net of unamortized debt discount, at $289 million as of December 31, 2012. As of December 31, 2013, affiliates of Berkshire Hathaway, Inc. held $56 million of these notes, which are reflected on our consolidated balance sheet, net of unamortized debt discount, at $54 million. Our consolidated statements of operations include the related interest expense of $29 million for the year ended December 31, 2013, and $31 million in each of the years ended December 31, 2012 and 2011, including the related accretion of the original debt discount. Our consolidated balance sheets as of December 31, 2013 and 2012 include the related accrued interest, in accrued expenses, of $0.5 million and $2.5 million, respectively. | ||||||||||||||||||||||||
The notes are senior unsecured obligations and rank equally with all of our other existing and future unsecured senior indebtedness. The indenture governing the notes contains events of default, covenants and restrictions that are customary for similar transactions, including a limitation on our ability and the ability of certain of our subsidiaries to create or incur secured indebtedness. The notes also contain a provision requiring us to offer to purchase the notes at a premium of 105% of their principal amount (plus accrued and unpaid interest) in the event of a change in control or the termination of trading of our common stock on a national securities exchange. | ||||||||||||||||||||||||
Credit Facility | ||||||||||||||||||||||||
Our credit facility 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. The credit facility is guaranteed by our significant domestic subsidiaries and secured by their and USG’s trade receivables and inventory. It is available to fund working capital needs and for other general corporate purposes. | ||||||||||||||||||||||||
Borrowings under the credit facility bear interest at a floating rate based on a base rate or, at our option, at the adjusted London Interbank Offering Rate, or LIBOR, plus 3.00%. We are also required to pay annual facility fees of 0.75% on the entire facility, whether drawn or undrawn, and fees on outstanding letters of credit. We have the ability to repay amounts outstanding under the credit agreement at any time without prepayment premium or penalty. The credit facility matures on December 21, 2015 unless terminated earlier in accordance with its terms. | ||||||||||||||||||||||||
The credit agreement 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 December 31, 2013, our fixed charge coverage ratio was 1.15-to-1. Because we currently satisfy the required fixed charge coverage ratio, we are not required to maintain a minimum borrowing availability under the credit facility. The credit agreement contains other covenants and events of default that are customary for similar agreements and may limit our ability to take various actions. The credit agreement limits our ability to pay a dividend or repurchase our stock unless specified borrowing availability and fixed charge coverage ratio tests are met, and it prohibits payment of a dividend if a default exists under the agreement. | ||||||||||||||||||||||||
Taking into account the most recent borrowing base calculation delivered under the credit facility, which reflects trade receivables and inventory as of December 31, 2013, and outstanding letters of credit, borrowings available under the credit facility were approximately $252 million. As of December 31, 2013 and during the year then-ended, there were no borrowings under the facility. Had there been any borrowings as of that date, the applicable interest rate would have been 3.3%. Outstanding letters of credit totaled $73 million as of December 31, 2013. | ||||||||||||||||||||||||
CGC Credit Facility | ||||||||||||||||||||||||
Our Canadian subsidiary, CGC Inc., or CGC, has a credit agreement with The Toronto-Dominion Bank which allows for revolving loans and letters of credit (up to Can. $3 million in aggregate) in an aggregate principal amount not to exceed Can. $40 million. The credit agreement matures on June 30, 2015, unless terminated earlier in accordance with its terms. The credit agreement is available for the general corporate purposes of CGC, excluding hostile acquisitions. The credit agreement is secured by a general security interest in substantially all of CGC’s assets other than intellectual property. As of December 31, 2013 and during the year then ended, there were no borrowings outstanding under this credit agreement. Had there been any borrowings as of that date, the applicable interest rate would have been 4.0%. As of December 31, 2013, outstanding letters of credit totaled Can. $0.8 million. The U.S. dollar equivalent of borrowings available under this agreement as of December 31, 2013 was $37 million. | ||||||||||||||||||||||||
Revolving loans under the agreement may be made in Canadian dollars or U.S. dollars. Under the credit agreement, revolving loans made in Canadian dollars bear interest at a floating rate based on the prime rate plus 1.25% or the Bankers’ Acceptance Discount Rate plus 2.75%, at the option of CGC. Revolving loans made in U.S. dollars bear interest at a floating rate based upon a base rate plus 1.25% or the LIBOR rate plus 2.75%, at the option of CGC. CGC may prepay the revolving loans at its discretion without premium or penalty and may be required to repay revolving loans under certain circumstances. | ||||||||||||||||||||||||
The credit agreement contains customary representations and warranties, affirmative and negative covenants that may limit CGC’s ability to take certain actions and events of default. Borrowings under the credit agreement are subject to acceleration upon the occurrence of an event of default. | ||||||||||||||||||||||||
Oman Credit Facilities | ||||||||||||||||||||||||
In June 2013, our joint ventures in Oman, which are fully consolidated, each entered into separate secured credit agreements, which are guaranteed by us and our joint venture partner. The credit agreement for Zawawi Gypsum LLC, or ZGL, which matures in 2020, provides for term loans not to exceed $10 million and overdraft and letter of credit facilities of approximately $3 million in the aggregate. The credit agreement for USG-Zawawi Drywall LLC, or ZDL, which matures in 2022, provides for term loans not to exceed $26 million and overdraft and letter of credit facilities of $5 million in the aggregate. Each credit agreement is secured by a general security interest in the applicable joint venture's assets. Loans under the credit agreements may be made in Omani Rial or U.S. dollars. Loans made in Omani Rial bear interest at 4% and loans made in U.S. dollars bear interest at a floating rate based on LIBOR plus 3.5%. Loans may be repaid at any time, subject to a prepayment penalty if repaid within the first two years, for ZGL, or three years, for ZDL. As of December 31, 2013, there were outstanding term loan borrowings of $10 million under the ZGL credit agreement and $1 million under the ZDL credit agreement, each with an average effective interest rate of 3.8%. See Note 21 for discussion of our contribution of ZGL and ZDL, and the corresponding Oman credit facilities, into the USG Boral Joint Venture on February 27, 2014. | ||||||||||||||||||||||||
Ship Mortgage Facility | ||||||||||||||||||||||||
Our subsidiary, Gypsum Transportation Limited, or GTL, has a secured loan facility agreement with DVB Bank SE, as lender, agent and security trustee. Both advances provided for under the secured loan facility have been drawn, and the total outstanding loan balances under the facility were $25 million as of December 31, 2013 and $29 million as of December 31, 2012. Of the total amounts outstanding on our consolidated balance sheets as of December 31, 2013 and December 31, 2012, $4 million was classified as current portion of long-term debt as of both financial statement dates. | ||||||||||||||||||||||||
The loan balance under the secured loan facility bears interest at a floating rate based on LIBOR plus a margin of 1.65%. The interest rate was 1.92% as of December 31, 2013. Each advance is repayable in quarterly installments in amounts determined in accordance with the secured loan facility agreement, with the balance of each advance repayable eight years after the date it was advanced, or October 31, 2016 and May 22, 2017. The secured loan facility agreement contains affirmative and negative covenants affecting GTL and certain customary events of default. GTL has granted DVB Bank SE a security interest in the Gypsum Centennial and Gypsum Integrity ships and related insurance, contract, account and other rights as security for borrowings under the secured loan facility.

COMMODITY DERIVATIVE INSTRUMENTS | ||||||||||||||||||||||||||
As of December 31, 2013, we had 14 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, 2014. For contracts designated as cash flow hedges, the unrealized gain that remained in AOCI as of December 31, 2013 was $1 million. No ineffectiveness was recorded on contracts designated as cash flow hedges in 2013. 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 regular basis. Changes in fair value on contracts not designated as cash flow hedges are recorded to earnings. The fair value of those contracts not designated as cash flow hedges was a $2 million unrealized gain as of December 31, 2013. | ||||||||||||||||||||||||||
FOREIGN EXCHANGE DERIVATIVE INSTRUMENTS | ||||||||||||||||||||||||||
We have foreign exchange forward contracts to hedge purchases of products and services denominated in foreign currencies. The notional amount of these contracts was $58 million as of December 31, 2013, and they mature by December 31, 2014. These forward contracts are designated as cash flow hedges and no ineffectiveness was recorded in 2013. 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 $1 million unrealized gain as of December 31, 2013. | ||||||||||||||||||||||||||
During the third quarter of 2012, we entered into foreign exchange forward contracts to hedge a portion of our net investment in one of our European subsidiaries. The notional amount of these contracts was $25 million and they matured on October 29, 2012. These forward contracts were designated as net investment hedges and no ineffectiveness was recorded in the fourth quarter. Gains and losses on derivatives designated as net investment hedges, to the extent they are effective as hedges, remain in AOCI until such point when the investment is either sold or liquidated. On December 27, 2012, we sold the subsidiary and, as a result, we reclassified the $1 million loss from AOCI to earnings as a reduction to the gain on the sale of the businesses. See Note 3 for further discussion on the sale. | ||||||||||||||||||||||||||
COUNTERPARTY RISK | ||||||||||||||||||||||||||
We are exposed to credit losses in the event of nonperformance by the counterparties to our derivative instruments. As of December 31, 2013, our derivatives were in a $5 million net asset 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 December 31, 2013, we were not required to have any collateral posted with our counterparties related to our derivatives. As required by certain of our agreements, we had $1 million of collateral posted with our counterparties related to our derivatives as of December 31, 2012. Amounts paid as cash collateral are included in receivables on our consolidated balance sheets. | ||||||||||||||||||||||||||
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. | ||||||||||||||||||||||||||

Fair Value Measurements | ||||||||||||||||||||||||||||||||
Certain assets and liabilities are required to be recorded at fair value. The fair values of our cash equivalents, marketable securities and derivatives were determined using the fair value hierarchy of inputs described in Note 1. 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 and 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. | ||||||||||||||||||||||||||||||||

Certain assets and liabilities are measured at fair value on a nonrecurring basis rather than on an ongoing basis, but are subject to fair value adjustments in certain circumstances, such as when there is evidence of impairment or when a new liability is being established that requires fair value measurement. | ||||||||||||||||||||||||||||||||
During the second quarter of 2012, we reviewed our property, plant and equipment for potential impairment by comparing the carrying values of those assets with their estimated future undiscounted cash flows for their remaining useful lives and determined that impairment existed for machinery and equipment for a previously idled production line. We measured the fair value of that machinery and equipment as of June 30, 2012 using measurements classified as Level 3. As a result, as disclosed in Note 12, we recorded long-lived asset impairment charges of $1 million that are included in restructuring and long-lived asset impairment charges in the consolidated statements of operations for 2012. | ||||||||||||||||||||||||||||||||
During the third quarter of 2011, we decided that we would permanently close our gypsum quarry and ship loading facility in Windsor, Nova Scotia, Canada. We measured the fair value of the Windsor real property, buildings, machinery and equipment as of September 30, 2011 by evaluating the current economic conditions for similar use assets using measurements classified as Level 3 and maximizing the use of available and reliable inputs observable in the marketplace. The fair value of the real property and buildings was estimated after considering a range of possible outcomes based on recent comparable sales and similar properties currently being marketed. Due to the lack of an established secondary market for the machinery and equipment and the lack of an income stream attributable to the machinery and equipment, the fair values were developed based upon a market approach considering comparable equipment adjusted for condition, age, functionality, obsolescence, marketability and location. As a result of our evaluation, long-lived Windsor assets with a carrying amount of $59 million were written down to their fair value of $6 million, resulting in a long-lived asset impairment charge of $53 million that was included in the consolidated statement of operations for 2011. During the fourth quarter of 2012, as a result of a change in estimate related to reclamation activities, we increased the related asset retirement obligation by $7 million with a corresponding increase to the long-lived Windsor assets. See Notes 11 and 12. Consequently, we recorded a long-lived asset impairment charge of $7 million to impair the assets down to a fair value of $6 million. |

Employee Retirement Plans | ||||||||||||||||||||||||||||||||
We maintain defined benefit pension plans for most of our employees. Most of these plans require employee contributions in order to accrue benefits. Benefits payable under the plans are based on employees’ years of service and compensation during specified years of employment. Effective December 31, 2010, we amended the USG Corporation defined benefit pension plan to replace the final average pay formula with a cash balance formula for employees hired after that date. | ||||||||||||||||||||||||||||||||
We also maintain plans that provide postretirement benefits (retiree health care and life insurance) for eligible employees. Employees hired before January 1, 2002 generally become eligible for the postretirement benefit plans when they meet minimum retirement age and service requirements. The cost of providing most postretirement benefits is shared with retirees. | ||||||||||||||||||||||||||||||||
In 2013, we communicated to certain terminated vested participants in our USG Corporation Retirement Plan an option to receive a lump sum payment for their accrued benefits. The option commenced on October 1, 2013 and expired on November 15, 2013. For participants who elected this option, payments were made in December 2013 and we incurred a settlement charge of approximately $15 million, with a corresponding reduction in accumulated other comprehensive loss. As a result, the measurement of the pension benefit obligation, or PBO, as of December 31, 2013 included a reduction of approximately $80 million. | ||||||||||||||||||||||||||||||||
In 2011, we amended our U.S. postretirement benefit plan to require retiree medical plan participants to begin purchasing individual coverage in the Affordable Insurance Exchanges or individual Medicare marketplace beginning January 1, 2015 using a company-funded subsidy. The subsidy will be determined based upon years of service at retirement and Medicare eligibility. The subsidy provided to retirees eligible for Medicare will end December 31, 2019. As a result of the amendment, the measurement of the accumulated postretirement benefit obligation, or APBO, as of December 31, 2011 includes a reduction of approximately $100 million. This amendment was accounted for as a credit to unrecognized prior service cost which will be amortized into the statement of operations over the average remaining service of active plan participants to retirement eligibility. | ||||||||||||||||||||||||||||||||
In 2010, we converted our prescription drug program for retirees over the age of 65 to a group-based company sponsored Medicare Part D program, or Employer Group Waiver Plan, or EGWP. Beginning in 2012, we use the Part D subsidies delivered through the EGWP each year to reduce net company retiree medical costs until net company costs are completely eliminated. When those costs are eliminated, the Part D subsidies will be shared with retirees to reduce retiree contributions. The amount of the subsidies shared with retirees will reflect the various subsidy levels of our plan (subsidies vary by years of service at retirement). We formally adopted this change effective with the December 31, 2010 measurement of our liability for retiree medical costs. As a result, in the fourth quarter of 2010, we reduced our APBO by approximately $47 million and unrecognized prior service cost by the same amount. The credit to unrecognized prior service cost is being amortized into the statement of operations over the average remaining service of active plan participants to retirement eligibility. | ||||||||||||||||||||||||||||||||

For our defined benefit pension plans, the 2013 actuarial gain of $115 million is primarily due to an increase in the discount rates used to determine the benefit obligation. The weighted-average discount rate increased from 4.20% at December 31, 2012 to 4.90% at December 31, 2013. The 2012 actuarial loss of $164 million was primarily due to reductions in discount rates used to determine the benefit obligation. The weighted-average discount rate used to determine the benefit obligation decreased from 4.95% at December 31, 2011 to 4.20% at December 31, 2012. | ||||||||||||||||||||||||||||||||
For the defined benefit pension plans, we estimate that during 2014 we will amortize from AOCI into net pension cost a net actuarial loss of $22 million and prior service cost of $1 million. For the postretirement benefit plans, we estimate that during 2014 we will amortize from AOCI into net postretirement cost a net actuarial loss of $1 million and a prior service credit of $36 million. | ||||||||||||||||||||||||||||||||

* Compensation increase rate and expected return on plan assets only applicable to our defined benefit pension plans. | ||||||||||||||||||||||||||||||||
For the measurement of the APBO at December 31, 2013 for our U.S. postretirement health care plan, the assumed health care cost trend rates start with an 8.00% increase in 2014, followed by a gradual decline in increases to 5.00% for 2020 and beyond. For the measurement of the APBO at December 31, 2012, the assumed health care cost trend rates started with a 7.10% increase in 2013, followed by a gradual decline in increases to 5.25% for 2016 and beyond. | ||||||||||||||||||||||||||||||||
Assumed health care cost trend rates can have a significant effect on the amounts reported for retiree health care costs. Effective January 1, 2011, we modified our U.S. postretirement health care plan to limit the increase in the annual amount we pay for retiree health care coverage for certain current and future retirees to 3% per year, which mitigates the impact of the increasing health care cost trend rates, as any additional increase will be the responsibility of plan participants. However, after January 1, 2015, due to the changes to the U.S. postretirement health care plan announced in 2011, as previously described, we will no longer have a material exposure to health care cost inflation for that plan. | ||||||||||||||||||||||||||||||||
For the measurement of the APBO at December 31, 2013 for our Canadian postretirement health care plan, the assumed health care cost trend rates start with a 8.5% increase in 2014, followed by a gradual decline in increases to 4% for 2032. For the measurement of the APBO at December 31, 2012, the assumed health care cost trend rates started with a 8.75% increase in 2013, followed by a gradual decline in increases to 4% for 2032 and beyond. | ||||||||||||||||||||||||||||||||

RETIREMENT PLAN ASSETS | ||||||||||||||||||||||||||||||||
Investment Policies and Strategies: We have established investment policies and strategies for the defined benefit pension plans’ assets with a long-term objective of maintaining the plans’ assets at a level equal to or greater than that of their liabilities (as measured by a funded ratio of 100% or more of the ABO) and maximizing returns on the plans’ assets consistent with our moderate tolerance for risk. Contributions are made to the plans periodically as needed to meet funding targets or requirements. Factors influencing our determination to accept a moderate degree of risk include the timing of plan participants’ retirements and the resulting disbursement of retirement benefits, the liquidity requirements of the plans and our financial condition. | ||||||||||||||||||||||||||||||||
Our overall long-term objective is to achieve a 7.0% rate of return on plan assets with a moderate level of risk as indicated by the volatility of investment returns. This rate of return target was established using a “building block” approach. In this approach, ranges of long-term expected returns for the various asset classes in which the plans invest are estimated. The estimated ranges are primarily based on observations of historical asset returns and their historical volatility. In determining the expected returns, we also consider consensus forecasts of certain market and economic factors that influence returns, such as inflation, gross domestic product trends and dividend yields. We then calculate an overall range of likely expected rates of return by applying the expected asset returns to the plans’ target asset allocation. The most likely rate of return is then determined and is adjusted to account for investment management fees. | ||||||||||||||||||||||||||||||||
Our investment strategy is to invest in a diversified mix of asset classes in accordance with an asset allocation that we believe is likely to achieve our long-term target return while prudently considering risk. This strategy recognizes that many investment professionals believe that certain asset classes, such as equities, may be expected to produce the greatest return in excess of inflation over time, but may also generate the greatest level of volatility. Conversely, many investment professionals believe that an asset class such as fixed income securities may be likely to be less volatile, but may also produce lower returns over time. In order to manage risk, the plans’ pension and investment committees periodically rebalance their asset allocations and monitor the investment performance of the individual investment managers compared to their benchmark returns and investment guidelines on an ongoing basis, in part through the use of quarterly investment portfolio reviews and compliance reporting by investment managers. The pension and investment committees also evaluate risk by periodically conducting asset/liability studies to assess the correlation of the plans’ assets and liabilities and the degree of risk in the target asset allocations. The plans limit the use of leverage to select investment strategies where leverage is typically employed, such as private equity and real estate. Certain investment managers utilize derivatives, such as swaps, bond futures, and options, as part of their investment strategies. This is done primarily to gain a desired market exposure or manage factors such as interest rate risk or duration of a bond portfolio. The following table shows the aggregate target asset allocation on a weighted average basis for all the plans and the acceptable ranges around the targets as of December 31, 2013. | ||||||||||||||||||||||||||||||||

Equity investments are in institutional commingled/pooled equity funds, equity mutual funds and direct holdings of the common stock of U.S. and non-U.S. companies. Both the equity funds and direct holdings are invested in companies with a range of market capitalizations. This category also includes an investment in USG Corporation shares of common stock as described below. Fixed income securities include U.S. Treasury securities, non-U.S. government debt securities such as Canadian federal bonds, corporate bonds of companies from diversified industries and mortgage-backed securities. Limited partnerships include investments in funds that follow any of several different strategies, including investing in distressed debt, energy development, infrastructure and a multi-strategy hedge fund. These investments use strategies with returns normally expected to have a reduced correlation to the return of equities as compared to other asset classes and often provide a current income component that is a meaningful portion of the investment’s total return. Real estate is primarily investments in large core, private real estate funds that directly own a diverse portfolio of properties located in the United States. | ||||||||||||||||||||||||||||||||
During 2012, we made contributions to our pension plans that included 1,249,219 shares of our common stock, or the Contributed Shares. The Contributed Shares were contributed to the USG Corporation Retirement Plan Trust, or Trust, and were recorded on the consolidated balance sheet at the June 25, 2012 closing price of $16.48 per share, or approximately $20.6 million in the aggregate. The Contributed Shares are not reflected on the consolidated statement of cash flows because they were treated as a noncash financing activity. The Contributed Shares were valued for purposes of crediting the contribution to the Trust at a discounted value of $16.01 per share ($16.48 less a 2.8% discount), or approximately $20 million in the aggregate, by an independent appraiser retained by Evercore Trust Company, N.A., or Evercore, an independent fiduciary that has been appointed as investment manager with respect to the Contributed Shares. The Contributed Shares are registered for resale, and Evercore has authority to sell some or all of them, as well as other of our shares in the Trust, in its discretion as fiduciary. The remainder of our 2012 pension plan contributions, and all of our 2013 contributions, were made in cash. The Trust held no shares of our common stock as of December 31, 2013. | ||||||||||||||||||||||||||||||||
Fair Values of Plan Assets: | ||||||||||||||||||||||||||||||||
Pension assets are classified based on the valuation methodologies and inputs used to determine the fair value as described in Note 1. | ||||||||||||||||||||||||||||||||
Level 1 investments include mutual funds, or direct investments in common stocks of U.S. and non-U.S. companies that trade on liquid exchanges. These investments are valued based on the closing price on these exchanges. | ||||||||||||||||||||||||||||||||
Level 2 investments include primarily fixed income securities such as corporate, or government debentures, mortgage- and asset-backed securities. They are valued using income and market 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. Commingled funds not traded on an exchange, even though their underlying investments are common stocks traded on liquid exchanges, are also included in the Level 2 category. The net asset value of commingled funds investing in either stocks or fixed income securities is calculated by subtracting the value of any liabilities from the market value of all securities owned by a fund. | ||||||||||||||||||||||||||||||||
Level 3 investments include real estate, infrastructure, or direct energy investments as well as distressed securities or hedge funds. These are valued using income approach methodologies such as discounted cash flows, or market approach methodologies such as relative value (specific to equity securities), direct capitalization and comparable sales (specific to real estate investments). Some of the key inputs used to value these securities include discount rate, EBITDA multiple, yield-to-worst, yield-to-maturity, and cap rate (specific to real estate investments). | ||||||||||||||||||||||||||||||||

(a) | The majority of these funds are invested with investment managers that invest in common stocks of large capitalization U.S. companies. Approximately 82% of these investments are actively managed. USG common stock represents 424,219 shares of New York Stock Exchange listed common stock at December 31, 2012.

CASH FLOWS | ||||||||||||||||||||||||||||||||
For 2014, our defined benefit pension plans have no minimum funding requirements under the Employee Retirement Income Security Act of 1974. We are evaluating our level of funding for pension plans and currently estimate that we will contribute approximately $59 million to our pension plans in 2014. Our cash payments for postretirement plans are estimated to be $13 million in 2014. | ||||||||||||||||||||||||||||||||
Total benefit payments we expect to make to participants, which include payments funded from USG’s assets as well as payments from our pension plans' assets, are as follows (in millions): | ||||||||||||||||||||||||||||||||

Total charges for our defined contribution plans amounted to approximately $3 million in each of the years ended December 31, 2013, 2012 and 2011 and primarily consisted of contributions to our U.S. plan, commonly known as a 401(k) plan. The U.S. plan provides participating employees the opportunity to invest 1% to 50% of their compensation on a pretax basis in any of 21 investment options offered, subject to limitations on the amount that may be contributed by highly compensated employees. Participants earned a guaranteed company match of 10% on their contributions of up to 6% of their eligible compensation during 2013, 2012 and 2011. Effective as of January 1, 2014, the company match was increased to 25% of employee contributions up to 6% of their pay. Employees are fully vested in company matching contributions after three years of participation in the plan. USG’s contributions are charged to cost of products sold and selling and administrative expenses. |

Share Based Compensation | ' | ||||||||||||
Share-Based Compensation | |||||||||||||
We grant share-based compensation to eligible participants under our amended Long-Term Incentive Plan, or LTIP. The LTIP was approved by our Board of Directors and stockholders. As of December 31, 2013, a total of 12.7 million shares of common stock were authorized for grants under the LTIP, of which 3.2 million shares were reserved for future grants. The LTIP authorizes the Board, or the Board’s Compensation and Organization Committee, to provide equity-based compensation in the form of stock options, stock appreciation rights, or SARs, restricted stock, restricted stock units, or RSUs, market share units, or MSUs, performance shares and units, and other cash and share-based awards for the purpose of providing our directors, officers and other employees incentives and rewards for performance. We may issue common shares upon option exercises and upon the vesting or grant of other awards under the LTIP from our authorized but unissued shares or from treasury shares. | |||||||||||||
Our expense for share-based arrangements was $19 million in 2013, $17 million in 2012 and $21 million in 2011 and is included in selling and administrative expense in our consolidated statements of operations. No income tax benefits were recognized for share-based arrangements in the consolidated statements of operations in 2013, 2012 and 2011. We recognize expense on all share-based awards over the service period, which is the shorter of the period until the employees’ retirement eligibility dates or the service period of the award for awards expected to vest. Accordingly, expense is generally reduced for estimated forfeitures. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. | |||||||||||||
STOCK OPTIONS | |||||||||||||
We granted stock options in 2012 and 2011 with exercise prices set at the closing price of USG common stock on the date of grant. The stock options generally become exercisable in four equal annual installments beginning one year from the date of grant, although they may become exercisable earlier in the event of death, disability, retirement or a change in control. The stock options generally expire ten years from the date of grant, or earlier in the event of death, disability or retirement. | |||||||||||||
We estimated the fair value of each stock option granted on the date of grant using a Black-Scholes option valuation model that uses the assumptions noted in the following table. We based expected volatility on a 50% weighting of our historical volatilities and 50% weighting of implied USG volatilities. The risk-free rate was based on zero-coupon U.S. government issues at the time of grant. The expected term was developed using the simplified method, as permitted by the Securities and Exchange Commission because there is not sufficient historical stock option exercise experience available. | |||||||||||||

The weighted average grant date fair value was $8.39 for options granted during 2012 and $10.60 for options granted during 2011. | |||||||||||||
Intrinsic value for stock options is defined as the difference between the current market value of our common stock and the exercise price of the stock options. The total intrinsic value of stock options exercised was $7 million in 2013, $7 million in 2012 and less than $1 million in 2011 and cash received from the exercise of stock options was $4 million in 2013, $4 million in 2012 and less than $1 million in 2011. As a result of the NOL we reported for federal tax purposes for 2013, 2012 and 2011, none of the excess tax benefit with respect to these exercises has been reflected in additional paid-in capital as of December 31, 2013. Included in our federal tax NOL carryforwards is $47 million for which a tax benefit of $17 million will be recorded in additional paid-in capital if the loss carryforward is utilized. | |||||||||||||
As of December 31, 2013, there was $2 million of total unrecognized compensation cost related to nonvested share-based compensation awards represented by stock options granted under the LTIP. We expect that cost to be recognized over a weighted average period of 1.9 years. The total fair value of stock options vested was $10 million during 2013, $5 million during 2012 and $14 million during 2011. | |||||||||||||
MARKET SHARE UNITS | |||||||||||||
We granted market share units, or MSUs, during 2013. Generally, half of the MSUs vest after a two-year period and the other half after a three-year period, in each case, based on our actual stock price performance during such periods. The number of MSUs earned will vary from 0% 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 2013. Awards earned will be issued at the end of the two-year and three-year periods. MSUs may vest earlier in the case of a change in control. 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 following table. Volatility was based on stock price history immediately prior to grant for a period commensurate with the expected term. The risk-free rate was based on zero-coupon U.S. government issues at the time of grant. The expected term represents the period from the valuation date to the end of the performance period. | |||||||||||||

RESTRICTED STOCK UNITS | |||||||||||||
We granted RSUs during 2013, 2012 and 2011. RSUs granted prior to 2013 generally vest in four equal annual installments beginning four years from the date of grant. RSUs granted as special retention awards, including those granted in 2013, generally vest after a specified number of years from the date of grant or at a specified date and RSUs granted with performance goals vest if those goals are attained. RSUs may vest earlier in the case of death, disability, retirement or a change in control. 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 market price of our common stock on the date of grant. | |||||||||||||
In 2013, we granted RSUs as special retention awards with respect to 39,500 shares of common stock that vest in four years from the date of grant. | |||||||||||||

The total fair value of RSUs that vested was $7 million during 2013, $13 million during 2012 and $5 million during 2011. | |||||||||||||
PERFORMANCE SHARES | |||||||||||||
We granted performance shares during 2013, 2012 and 2011. The performance shares generally vest after a period of three years 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 0% to 200% of the number of performance shares awarded depending on that relative performance. Vesting will be pro-rated based on the number of full months employed during the performance period in the case of death, disability, retirement or a change in control, and pro-rated awards earned will be paid 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 uses the assumptions noted in the following table. Expected volatility is based on implied volatility of our traded options and the daily historical volatilities of our peer group. The risk-free rate was based on zero coupon U.S. government issues at the time of grant. The expected term represents the period from the grant date to the end of the three-year performance period. | |||||||||||||

The remaining performance shares granted in 2011 were previously forfeited. | |||||||||||||
Total unrecognized compensation cost related to nonvested share-based compensation awards represented by performance shares granted under the LTIP was $4 million as of December 31, 2013. We expect that cost to be recognized over a weighted average period of 1.7 years. | |||||||||||||
NON-EMPLOYEE DIRECTOR DEFERRED STOCK UNITS | |||||||||||||
Our non-employee directors may elect to receive a portion of their compensation as deferred stock units that increase or decrease in value in direct relation to the market price of our common stock. Deferred stock units earned through December 31, 2007 will be paid in cash upon termination of board service. Deferred stock units earned thereafter will be paid in cash or shares of USG common stock, at the election of the director, upon termination of board service. | |||||||||||||
The number of deferred stock units held by non-employee directors was approximately 182,632 as of December 31, 2013, 172,124 as of December 31, 2012 and 163,627 as of December 31, 2011. We recorded expense related to these deferred stock units of $1 million in 2013, $3 million in 2012 and zero in 2011. |

(a) Changes in estimated cash flows for the year ended December 31, 2012 include $7 million resulting from a change in estimate related to reclamation activities for our gypsum quarry and ship loading facility in Windsor, Nova Scotia, Canada which we permanently closed during the third quarter of 2011. | ||||||||||||||||
Our asset retirement obligations include reclamation requirements as regulated by government authorities related principally to assets such as our mines, quarries, landfills, ponds and wells. The accounting for asset retirement obligations requires estimates by management about the timing of asset retirements, the cost of retirement obligations, discount and inflation rates used in determining fair values and the methods of remediation associated with our asset retirement obligations. We generally use assumptions and estimates that reflect the most likely remediation method on a site-by-site basis. Our estimated liability for asset retirement obligations is revised annually, and whenever events or changes in circumstances indicate that a revision to the estimate is necessary. | ||||||||||||||||
In instances where a decrease in the asset retirement obligation is in excess of the related remaining net book value of the asset retirement costs, the excess is recorded to the consolidated statement of operations as a reduction in cost of products sold. Asset retirement obligations are included in other liabilities on the consolidated balance sheets. |

As part of our continuing efforts to adapt our operations to market conditions, we implemented restructuring activities in 2013, 2012 and 2011 that resulted in the following restructuring and long-lived asset impairment charges: | ||||||||||||||||||||

Total | $ | 3 | $ | 18 | $ | 75 | ||||||||||||||
* | During the fourth quarter of 2012, as a result of a change in estimate related to reclamation activities, we increased the related asset retirement obligation by $7 million with a corresponding increase to the long-lived assets at this facility. Consequently, we recorded a long-lived asset impairment charge of $7 million to write the assets down to their fair value of $6 million. See Note 11. The 2011 charges include $42 million related to the write-down of the carrying values of long-lived assets at this facility and $11 million related to the acceleration of the facility’s asset retirement obligation. | |||||||||||||||||||
2013 | ||||||||||||||||||||
Total charges of $3 million primarily consisted of severance related to various cost-reduction programs, including our December 2012 management workforce reduction and salaried workforce reductions across various functional areas resulting from our initiatives to centralize and consolidate certain back-office operations as well as other exit costs. See Note 13 for restructuring charges by segment. | ||||||||||||||||||||
2012 | ||||||||||||||||||||
Total charges of $18 million primarily related to the permanent closure of our gypsum quarry and ship loading facility in Windsor, Nova Scotia, Canada and salaried workforce reductions. As a result of these actions, the number of salaried employees terminated and open salaried positions eliminated was approximately 90 and the number of hourly employees terminated and open hourly positions eliminated was approximately 40. | ||||||||||||||||||||
2011 | ||||||||||||||||||||
Total charges of $75 million primarily related to the permanent closure of our gypsum quarry and ship loading facility in Windsor, Nova Scotia, Canada, L&W Supply Corporation's closure of nine distribution branches and its Nevada custom door and frames business and a salaried workforce reduction. As a result of these actions, the number of salaried employees terminated and open salaried positions eliminated was approximately 115 and the number of hourly employees terminated and open hourly positions eliminated was approximately 90. | ||||||||||||||||||||
Restructuring Reserve | ||||||||||||||||||||
A restructuring reserve of $11 million was included in accrued expenses and other liabilities on the consolidated balance sheet as of December 31, 2013. We expect future payments to be approximately $3 million in 2014, $3 million in 2015 and $5 million after 2015. On a segment basis, $1 million of all expected future payments relate to North American Gypsum, $8 million to Building Products Distribution and $2 million to Corporate. All restructuring-related payments were funded with cash on hand. We expect that the future payments will be funded with cash from operations or cash on hand. | ||||||||||||||||||||

We have established a valuation allowance in the amount of $995 million consisting of $735 million for federal deferred tax assets, $256 million for state deferred tax assets and $4 million for foreign deferred tax assets. | ||||||||||||
We reduce the carrying amounts of deferred tax assets by a valuation allowance if, based on the available evidence, it is more likely than not that such assets will not be realized. The need to establish valuation allowances for deferred tax assets is assessed periodically. In assessing the requirement for, and amount of, a valuation allowance in accordance with the more-likely-than-not standard, we give appropriate consideration to all positive and negative evidence related to the realization of the deferred tax assets. This assessment considers, among other matters, the nature, frequency and severity of current and cumulative losses, forecasts of future profitability, the duration of statutory carryforward periods, our experience with operating loss and tax credit carryforwards not expiring unused and tax planning alternatives. A history of cumulative losses for a certain threshold period is a significant form of negative evidence used in our assessment. Consistent with practices in the home building and related industries, we have a policy of four years as our threshold period for cumulative losses. If a cumulative loss threshold is met, forecasts of future profitability are not used as positive evidence related to the realization of the deferred tax assets in the assessment. | ||||||||||||
As of December 31, 2013, we had federal NOL carryforwards of approximately $2.067 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 alternative minimum tax 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 the U.S. federal net deferred tax assets, taxable income of approximately $2.197 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 December 31, 2013, we had a gross deferred tax asset of $270 million related to state NOLs and tax credit carryforwards, of which $11 million will expire in 2014. The remainder will expire if unused in years 2015 through 2033. To the extent that we do not generate sufficient state taxable income within the statutory carryforward periods to utilize the NOL and tax credit carryforwards in these states, they will expire unused. | ||||||||||||
We also had NOL and tax credit carryforwards in various foreign jurisdictions in the amount of $2 million and $1 million as of December 31, 2013 and 2012, respectively, against a portion of which we have historically maintained a valuation allowance. | ||||||||||||
During periods prior to 2013, we established a valuation allowance against our deferred tax assets totaling $1.125 billion. Based upon an evaluation of all available evidence, we recorded a decrease in the valuation allowance against our deferred tax assets of $130 million in 2013. The decrease related to discrete items is $125 million, including a decrease in the deferred tax assets for pension and state net operating losses, and the remaining decrease of $5 million is related to current year earnings. As a result, our deferred tax assets valuation allowance is $995 million as of December 31, 2013. 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. Our net deferred tax assets were $3 million as of December 31, 2013 and $13 million as of December 31, 2012. | ||||||||||||
The Internal Revenue Code imposes limitations on a corporation’s ability to utilize NOLs if it experiences an “ownership change.” In general terms, an ownership change may result from transactions increasing the ownership of certain stockholders in the stock of a corporation by more than 50 percentage points over a three-year period. If we were to experience an ownership change, utilization of our NOLs would be subject to an annual limitation determined by multiplying the market value of our outstanding shares of stock at the time of the ownership change by the applicable long-term tax-exempt rate, which was 3.50% for December 2013. 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 December 31, 2013, our annual U.S. federal NOL utilization would have been limited to approximately $136 million per year. | ||||||||||||

We classify interest expense and penalties related to unrecognized tax benefits and interest income on tax overpayments as components of income taxes (benefit). The total amounts of interest expense and penalties recognized on our consolidated balance sheets were $2 million and $1 million, respectively, as of December 31, 2013 and December 31, 2012. The total amounts of interest and penalties recognized in our consolidated statements of operations was zero in 2013, $1 million for 2012 and $(1) million for 2011. The total amounts of unrecognized tax benefit that, if recognized, would affect our effective tax rate were $7 million for 2013, $7 million for 2012 and $8 million for 2011. | ||||||||||||
Our federal income tax returns for 2008 and prior years have been examined by the Internal Revenue Service. The U.S. federal statute of limitations remains open for the year 2006 and later years. We are under examination in various U.S. state and foreign jurisdictions. It is possible that these examinations may be resolved within the next 12 months. Due to the potential for resolution of the examinations and the expiration of various statutes of limitations, it is reasonably possible that our gross unrecognized tax benefit may change within the next 12 months by a range of $0 million to $4 million. Foreign and U.S. state jurisdictions have statutes of limitations generally ranging from three to five years. | ||||||||||||
We do not provide for U.S. income taxes on the portion of undistributed earnings of foreign subsidiaries that is intended to be permanently reinvested. The cumulative amount of such undistributed earnings totaled approximately $642 million as of December 31, 2013. These earnings would become taxable in the United States upon the sale or liquidation of these foreign subsidiaries or upon the remittance of dividends. The estimate of the amount of the deferred tax liability on such earnings is $26 million, consisting of foreign withholding taxes. |

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, for $16 million, including transaction costs. ZGL is developing the infrastructure and operating the quarry. 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, with Zawawi Minerals LLC to build and operate a low cost wallboard plant in Oman. The plant site is in close proximity to the gypsum quarry and port facilities, facilitating access into markets in India and the Middle East. We expect to commence wallboard production operations in the third quarter 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 will be 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 consolidated balance sheets. | |
We determined that both entities are variable interest entities (VIEs). We believe that we direct the activities that most significantly impact the VIEs through our appointment of the general manager, who oversees both ventures and whose responsibilities include developing infrastructure, operating the quarry and directing the entity's product development and pricing strategies. As such, we consolidate the VIEs and, in June 2012, in conjunction with the acquisition of the mining rights, we established a 45% noncontrolling interest of $13 million within stockholders' equity based upon the fair value of the mining rights, with a corresponding increase to the mining rights. There was no gain or loss recognized upon the initial consolidation of the mining VIE. | |
In January of 2013, under our strategic partnership agreement, we paid an additional $17 million to obtain additional mining rights. Concurrently, our joint venture partner who holds the noncontrolling interest contributed its share of the mining rights. Based upon the fair value of the mining rights, the noncontrolling interest within stockholders' equity increased by $13 million and the mining rights, reflected within property, plant and equipment, increased by $30 million. | |
During 2013, our joint venture partner provided loans of approximately $3 million to ZDL, which are included in other liabilities in our accompanying consolidated balance sheet as of December 31, 2013. Including these loans, and loans made in 2012 to ZDL and ZGL, other liabilities includes, in the aggregate, loans payable and the related accrued interest of approximately $8 million and $4 million as of December 31, 2013 and December 31, 2012, respectively. | |
During 2013, we provided loans of approximately $3 million to ZDL. Including these loans, we have provided $5 million of loans to ZDL and $3 million of loans to ZGL. Loans we make to these ventures are not reflected on our accompanying consolidated balance sheets because they are eliminated in consolidation. | |
See Note 6 for a description of the credit facilities entered into by our joint ventures in Oman in June 2013. | |

Stockholder Rights Plan | ' |
Stockholder Rights Plan | |
We have a stockholder rights plan, or the Rights Plan, established under the terms of a rights agreement dated December 21, 2006, as amended, with Computershare Trust Company N.A., as Rights Agent, or the Rights Agreement. Our board of directors adopted the Rights Plan to protect our stockholders from coercive takeover practices or takeover bids that are inconsistent with their best interests. | |
On March 22, 2013, our board of directors approved an amendment to the Rights Agreement in an effort to protect our NOL carryforwards during the effective period of the amendment. Under this amendment, if any person becomes the beneficial owner of 4.9% or more of our common stock, stockholders other than the 4.9% triggering stockholder will have the right to purchase additional shares of our common stock at half the market price, thereby diluting the triggering stockholder; provided that stockholders whose beneficial ownership exceeded 4.9% of our common stock outstanding on March 22, 2013 will not be deemed to have triggered the Rights Agreement, as amended, so long as they do not thereafter acquire additional common stock other than in certain specified exempt transactions. In addition, a person generally will not be deemed to have triggered the Rights Agreement, as amended, by virtue of the conversion of our convertible notes. | |
The amendment to the Rights Agreement is effective until the earlier of (i) March 22, 2016, (ii) the date on which our board of directors determines that the amendment is no longer necessary for the provision of certain tax benefits because of the repeal of Section 382 of the Internal Revenue Code, or Code, (iii) the first day of a taxable year as to which our board of directors determines that no tax benefits may be carried forward, or (iv) such other date as our board of directors determines that the amendment is no longer necessary for the preservation of tax benefits. Upon expiration of the amendment to the Rights Agreement, the triggering threshold level under the Rights Plan will revert to the 15% level in effect prior to the amendment, unless our board of directors determines otherwise. Our stockholders ratified, on an advisory basis, the amendment to the Rights Agreement at our 2013 annual meeting of stockholders. | |
Prior to the adoption of the amendments to the Rights Agreement described above, under the Rights Plan, if any person or group were to acquire beneficial ownership of 15% or more of our then-outstanding voting stock, stockholders other than the 15% triggering stockholder would have had the right to purchase additional shares of our common stock at half the market price, thereby diluting the triggering stockholder. The Rights Agreement also provides that Berkshire Hathaway (and certain of its affiliates) will not trigger the rights unless Berkshire Hathaway and its affiliates acquire beneficial ownership of more than 50% of our voting stock on a fully diluted basis. | |
The rights issued pursuant to the Rights Agreement will expire on January 2, 2017. However, our board of directors has the power to accelerate or extend the expiration date of the rights. In addition, a board committee composed solely of independent directors reviews the Rights Agreement at least once every three years to determine whether to modify the Rights Plan in light of all relevant factors. This review was most recently conducted in November 2012. The next review is required by the end of 2015. | |
On May 9, 2013, we filed an amendment to our Restated Certificate of Incorporation, or the Protective Amendment, that restricts certain transfers of our common stock. The Protective Amendment is intended to protect the tax benefits of our NOL carryforwards. See Note 14 for a description of our NOL carryforwards. Subject to certain limited exceptions, the Protective Amendment's transfer restrictions would restrict any person from transferring our common stock (or any interest in our common stock) if the transfer would result in a stockholder (or several stockholders, in the aggregate, who hold their stock as a “group” under Section 382 of the Code) owning 4.9% or more of our common stock. Any direct or indirect transfer attempted in violation of the Protective Amendment would be void as of the date of the prohibited transfer as to the purported transferee, and the purported transferee would not be recognized as the owner of the shares attempted to be owned in violation of the Protective Amendment for any purpose, including for purposes of voting and receiving dividends or other distributions in respect of that common stock, or in the case of options, receiving our common stock in respect of their exercise. The Protective Amendment is effective until the earlier of (i) May 9, 2016, (ii) the repeal of Section 382 of the Code if our board of directors determines that the Protective Amendment is no longer necessary for the preservation of tax benefits, (iii) the first day of a taxable year as to which our board of directors determines that no tax benefits may be carried forward, or (iv) such other date as determined by our board of directors pursuant to the Protective Amendment. |

Litigation | |
CHINESE-MANUFACTURED DRYWALL LAWSUITS | |
L&W Supply Corporation is one of many defendants in lawsuits relating to Chinese-made wallboard installed in homes primarily in the southeastern United States during 2006 and 2007. Most of the lawsuits are part of the multi-district class action litigation titled In re Chinese-Manufactured Drywall Products Liability Litigation, MDL No. 2047, pending in the United States District Court for the Eastern District of Louisiana. | |
The vast majority of the claims against L&W Supply Corporation relate to wallboard we delivered that was manufactured by Knauf Plasterboard (Tianjin) Co., or Knauf Tianjin, an affiliate of a multi-national manufacturer of building materials that also beneficially owns approximately 11% of USG's outstanding shares of common stock. We have reached settlement agreements with Knauf and the plaintiffs in the multi-district class action litigation that cap our responsibility for all claims against us for homes to which we delivered Knauf Tianjin wallboard. | |
As of December 31, 2013, we have an accrual of $6 million for our estimated cost of resolving all Chinese wallboard property damage claims pending against us and expected to be asserted in the future, and, based on the terms of our settlement with Knauf, we have a related receivable of $2 million recorded as an offset to the accrual. Our accrual does not take into account litigation costs, which are expensed as incurred, or any set-off for potential insurance recoveries. Based on the information available to us to date regarding the number and type of pending claims, estimates of likely future claims, and the estimated costs of resolving those claims, we believe that we have appropriately accrued for our exposure related to the Chinese wallboard claims, and we believe that these claims and other similar claims that might be asserted will not have a material effect on our results of operations, financial position or cash flows. | |
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 in the litigation 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. On behalf of this alleged direct purchaser class, the plaintiffs seek unspecified monetary damages, tripled under the antitrust laws, as well as pre-judgment interest, post-judgment interest and attorneys' fees. 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. Recently, 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 Inc., a subsidiary of USG Corporation, as well as other Canadian and U.S. wallboard manufacturers. | |
USG has denied the allegations made in these wallboard pricing lawsuits. The lawsuits are still in a preliminary stage involving the production of documents from all of the parties to the litigation, and the plaintiffs have not indicated the amount of damages that they seek. At this stage of the lawsuits, we are not able to estimate the amount, if any, of any reasonably possible loss or range of reasonably possible losses. However, based on the information known to us, we believe these 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 December 31, 2013, we have an accrual of $18 million for our probable and reasonably estimable liability in connection with these matters. As of December 31, 2012, we had an accrual of $14 million related to 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 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. |

Subsequent Event | |
On February 27, 2014, we and certain of our subsidiaries formed a 50/50 joint venture (the "USG Boral Joint Venture") with Boral Limited ("Boral") and certain of its subsidiaries. The USG Boral Joint Venture 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 USG and Boral manufacture and distribute through the USG Boral Joint Venture include products for wall, ceiling, floor lining and exterior systems that utilize gypsum, wallboard, mineral fiber ceiling tiles, steel grid and studs, joint compound and other products. | |
As consideration for our 50% ownership in the USG Boral Joint Venture, we made a $513 million cash payment to Boral, which includes a $500 million base price and $13 million of customary estimated working capital and net debt adjustments, contributed to the USG Boral Joint Venture our subsidiaries and joint venture investments in China, Singapore, India, Malaysia, New Zealand, Australia and the Middle East, including our joint ventures in Oman, and granted to the USG Boral Joint Venture a license 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 the USG Boral Joint Venture, 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. The cash portion of the consideration paid to Boral is subject to customary post-closing adjustments. | |
Our investment in the USG Boral Joint Venture will be accounted for as an equity method investment and initially measured at cost. Our existing wholly owned subsidiaries and consolidated variable interest entities that were contributed into the joint venture will be deconsolidated. |

Nature of Operations | ' | |
Nature of Operations | ||
USG, through its subsidiaries, is 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. Our products also are distributed through building materials dealers, home improvement centers and other retailers, specialty wallboard distributors, and contractors. | ||
Segments | ' | |
Segments | ||
Our operations are organized into three reportable segments: North American Gypsum, Worldwide Ceilings and Building Products Distribution. Our determination of the reportable segments was made on the basis of our strategic business units and the commonalities among the products within each segment, and corresponds to the manner in which management reviews and evaluates operating performance. Certain similar operating segments that meet applicable aggregation criteria have been combined. | ||
North American Gypsum manufactures SHEETROCK® brand gypsum wallboard and related products. Worldwide Ceilings manufactures ceiling tile in the United States and ceiling grid in the United States, Canada and the Asia-Pacific region. Building Products Distribution distributes gypsum wallboard, drywall metal, ceilings products, joint compound and other building products throughout the United States. | ||
Consolidation and Presentation | ' | |
Consolidation and Presentation | ||
Our consolidated financial statements include the accounts of USG Corporation, its majority-owned subsidiaries and variable interest entities. Entities in which we have more than a 20% but not more than 50% ownership interest are accounted for using the equity method of accounting and are not material to our consolidated operations. All intercompany balances and transactions are eliminated in consolidation. On our consolidated statements of cash flows for the years ended December 31, 2012 and 2011, a portion of the amounts previously included within "(Decrease) increase in other liabilities" have been reclassified to "(Decrease) increase in pension and other postretirement benefits" to conform to the current year presentation, and amounts previously included in "Receivables" have been reclassified to "Provision for Bad Debt." | ||
Use of Estimates | ' | |
Use of Estimates | ||
The preparation of our consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets, liabilities, revenues and expenses. Actual results could differ from these estimates. | ||
Revenue Recognition | ' | |
Revenue Recognition | ||
With the exception of our Building Products Distribution segment, we recognize revenue upon the shipment of products to customers, which is when title and risk of loss are transferred to customers, and our products are generally shipped free on board, commonly called FOB, shipping point. For Building Products Distribution, revenue is recognized and title and risk of loss are transferred when customers receive products, either through delivery by company trucks or customer pickup. We record provisions for discounts to customers based on the terms of sale in the same period in which the related sales are recorded. We record estimated reductions to revenue for customer programs and incentive offerings, including promotions and other volume-based incentives, in the period in which the sale occurs. | ||
Shipping and Handling Costs | ' | |
Shipping and Handling Costs | ||
Shipping and handling costs are included in cost of products sold. | ||
Advertising | ' | |
Advertising | ||
Advertising expenses consist of media advertising and related production costs and sponsorships. We charge advertising expenses to earnings as incurred. | ||
Research and Development | ' | |
Research and Development | ||
We charge research and development expenditures to earnings as incurred. | ||
Income Taxes | ' | |
Income Taxes | ||
We record income tax expense (benefit) under the asset and liability method. Under this method, deferred tax assets and liabilities are recognized based on the future tax consequences to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and attributable to net operating loss, or NOL, and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply in the years in which the temporary differences are expected to be recovered or paid. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in earnings in the period when the change is enacted. Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not that a tax benefit will not be realized. | ||
Inventory Valuation | ' | |
Inventory Valuation | ||
All of our inventories are stated at the lower of cost or market. Virtually all of our inventories are valued under the average cost method with the remainder valued under the first-in, first-out cost method. Inventories include materials, labor and applicable factory overhead costs. Depreciation associated with manufacturing assets is excluded from inventory cost, but is included in cost of products sold. | ||
Earnings (Loss) Per Share | ' | |
Earnings (Loss) per Share | ||
Basic earnings (loss) per share is based on the weighted average number of common shares outstanding. Diluted earnings per share is based on the weighted average number of common shares outstanding plus the dilutive effect, if any, of restricted stock units, or RSUs, and performance shares, the potential exercise of outstanding stock options and the potential conversion of our 10% convertible senior notes. | ||
Cash and Cash Equivalents | ' | |
Cash and Cash Equivalents | ||
Cash and cash equivalents include highly liquid investments, primarily money market funds, with maturities of three months or less at the time of purchase. | ||
Marketable Securities | ' | |
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), or AOCI. If it is deemed that marketable securities have unrealized losses that are other than temporary, these losses will be recorded in earnings immediately. Situations in which losses may be considered other than temporary include when we have decided to sell a security or when it is more likely than not that we will be required to sell the security before we recover its amortized cost basis. | ||
Receivables | ' | |
Receivables | ||
We include trade receivables in receivables on our consolidated balance sheets. Trade receivables are recorded at net realizable value, which includes allowances for cash discounts and doubtful accounts, and are reflected net of customer incentives. We review the collectability of trade receivables on an ongoing basis. We reserve for trade receivables determined to be uncollectible. This determination is based on the delinquency of the account, the financial condition of the customer and our collection experience. | ||
We include short-term financing receivables in receivables and long-term financing receivables in other assets on our consolidated balance sheets. Financing receivables are recorded at net realizable value which includes an allowance for credit losses. We review the collectability of financing receivables on an ongoing basis. We reserve for financing receivables determined to be uncollectible. This determination is based on the delinquency of the account and the financial condition of the other party. As of December 31, 2013, the allowance for credit losses was immaterial. | ||
Property, Plant and Equipment | ' | |
Property, Plant and Equipment | ||
Property, plant and equipment is recorded at cost. We record depreciation of property, plant and equipment on a straight-line basis over the expected useful lives of the assets. We have determined estimated useful lives to be 50 years for buildings and improvements, a range of 10 to 25 years for machinery and equipment, and 5 years for computer software and systems development costs. Leasehold improvements are capitalized and amortized over the shorter of the remaining lease term or remaining economic useful life. We capitalize interest during the active construction period of major capital projects. Capitalized interest is added to the cost of the underlying assets and is depreciated over the useful lives of those assets. There was $3 million of interest capitalized in 2013, and no interest was capitalized in 2012 or 2011. Facility start-up costs that cannot be capitalized are expensed as incurred and recorded in cost of products sold. We compute depletion on a basis calculated to spread the cost of gypsum and other applicable resources over the estimated quantities of material recoverable. We review property, plant and equipment for impairment when indicators of a potential impairment are present by comparing the carrying values of the assets with their estimated future undiscounted cash flows. If we determine an impairment exists, the asset is written down to estimated fair value. | ||
Intangible Assets | ' | |
Intangible Assets | ||
We perform impairment tests for intangible assets with indefinite useful lives as of October 31 of each year, or more frequently if events occur or circumstances change that would more likely than not reduce the fair value of an intangible asset below its carrying value. The impairment test consists of a comparison of the fair value of the asset with its carrying amount. If the carrying amount of an intangible asset exceeds its fair value, an impairment loss is recognized in an amount equal to that excess. Intangible assets determined to have indefinite useful lives, primarily comprised of trade names, are not amortized. An income approach is used for valuing trade names. Assumptions used in the income approach include projected revenues and assumed royalty, long-term growth and discount rates. We perform impairment tests on definite lived intangible assets, such as customer relationships, upon identification of events or circumstances that may indicate the carrying amount of the assets might be unrecoverable by comparing their undiscounted cash flows with their carrying value. If we determine impairment exists, the assets are written down to estimated fair value. | ||
Share-Based Compensation | ' | |
Share-Based Compensation | ||
We award share-based compensation to employees in the form of stock options, restricted stock units, market share units, and performance shares and to directors in the form of shares of our common stock. All grants under share-based payment programs are accounted for at fair value at the date of grant. We recognize expense on all share-based awards to employees expected to vest over the service period, which is the shorter of the period until the employees’ retirement eligibility dates or the service period of the award. | ||
Derivative Instruments | ' | |
Derivative Instruments | ||
We use derivative instruments to manage selected 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. All derivative instruments must be recorded on the balance sheet at fair value. For derivatives designated as fair value hedges, the changes in the fair values of both the derivative instrument and the hedged item are recognized in earnings in the current period. For derivatives designated as cash flow hedges, the effective portion of changes in the fair value of the derivative is recorded to AOCI, and is reclassified to earnings when the underlying forecasted transaction affects earnings. The ineffective portion of changes in the fair value of the derivative is reported in cost of products sold in the current period. We periodically reassess the probability of the underlying forecasted transaction occurring. For derivatives designated as net investment hedges, we record changes in fair value to AOCI. For derivatives not designated as hedging instruments, all changes in fair value are recorded to earnings in the current period. | ||
Currently, we are using swap and option contracts to hedge a significant portion of our anticipated purchases of natural gas to be used in our manufacturing operations. Generally, we hedge the cost of a majority of our anticipated purchases of natural gas over the next 12 months. However, we review our positions regularly and make adjustments as market conditions warrant. The majority of contracts currently in place are designated as cash flow hedges, and the remainder are not designated as hedging instruments. | ||
We have operations in a number of countries and use forward contracts from time-to-time to hedge the risk of changes in cash flows resulting from selected forecasted intercompany and third-party sales or purchases, as well as intercompany loans, denominated in non-U.S. currencies, or to hedge the risk of selected changes in our net investment in foreign subsidiaries. These contracts are designated as either cash flow hedges or net investment hedges or are not designated as hedging instruments. | ||
Foreign Currency Translation | ' | |
Foreign Currency Translation | ||
We translate foreign-currency-denominated assets and liabilities into U.S. dollars at the exchange rates existing as of the respective balance sheet dates. We translate income and expense items at the average exchange rates during the respective periods. We record translation adjustments resulting from fluctuations in exchange rates to AOCI on our consolidated balance sheets. We record transaction gains and losses to earnings. | ||
Fair Value Measurements | ' | |
Fair Value Measurements | ||
Certain assets and liabilities are required to be recorded at fair value. The estimated fair values of those assets and liabilities have been determined using market information and valuation methodologies. Changes in assumptions or estimation methods could affect the fair value estimates. However, we do not believe any such changes would have a material impact on our financial condition, results of operations or cash flows. There are three levels of inputs that may be used to measure fair value: | ||
• | Level 1 – Quoted prices for identical assets and liabilities in active markets; | |
• | Level 2 – 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; and | |
• | Level 3 – Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable. | |
Certain assets and liabilities are measured at fair value on a nonrecurring basis rather than on an ongoing basis, but are subject to fair value adjustments in certain circumstances, such as when there is evidence of impairment or when a new liability is being established that requires fair value measurement. |

Stock Options Valuation Assumptions | ' | ||||||||||||
We estimated the fair value of each stock option granted on the date of grant using a Black-Scholes option valuation model that uses the assumptions noted in the following table. We based expected volatility on a 50% weighting of our historical volatilities and 50% weighting of implied USG volatilities. The risk-free rate was based on zero-coupon U.S. government issues at the time of grant. The expected term was developed using the simplified method, as permitted by the Securities and Exchange Commission because there is not sufficient historical stock option exercise experience available. | |||||||||||||
