BUILDING MATERIALS CORPORATION OF AMERICA

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

Note 1. Formation of the Company

        Building Materials Corporation of America ("BMCA" or the "Company") was formed on January 31, 1994 and is a wholly-owned subsidiary of BMCA Holdings Corporation ("BHC"), which is a wholly-owned subsidiary of G-I Holdings Inc. ("G-I Holdings"). G-I Holdings is a wholly-owned subsidiary of G Holdings Inc. During the first quarter of 2007, BMCA acquired ElkCorp ("Elk"), a Dallas, Texas-based manufacturer of roofing products and building materials, resulting in Elk becoming an indirect wholly-owned subsidiary of BMCA.

        The consolidated financial statements of the Company reflect, in the opinion of management, all adjustments necessary to present fairly the financial position of the Company at April 5, 2009, and the results of its operations and its cash flows for the first quarter ended April 5, 2009 and March 30, 2008, respectively. All adjustments are of a normal recurring nature, except for the restructuring and other expenses recorded in the Company's statement of operations for the first quarter ended April 5, 2009 and March 30, 2008, respectively. See Note 3. Net sales of roofing products and specialty building products and accessories are generally seasonal in nature. Accordingly, the results of operations and cash flows in the respective quarterly ended periods will vary depending on the time of the year. These financial statements should be read in conjunction with the annual audited financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2008, which was filed with the Securities and Exchange Commission (the "SEC") on March 31, 2009 (the "2008 Form 10-K").

Note 2. New Accounting Pronouncements

        In December 2007, the Financial Accounting Standards Board ("FASB") issued Statement of Financial Accounting Standards ("SFAS") No. 141 (revised in 2007) "Business Combinations" ("SFAS No. 141R"), which provides revised guidance on how an acquiring company should recognize and measure the identifiable assets acquired, liabilities assumed, any noncontrolling interests, and goodwill acquired in a business combination. SFAS No. 141R also expands the required disclosures related to the nature and financial statement effects of business combinations and became effective on a prospective basis for business combinations completed in fiscal years beginning after December 15, 2008. The Company adopted the provisions of SFAS No. 141R during its first quarter beginning January 1, 2009, and the adoption did not have any impact on the Company's consolidated financial statements.

        In April 2009, the FASB issued FASB Staff Position ("FSP") FAS No. 141(R)-1, "Accounting for Assets Acquired and Liabilities Assumed in a Business Combination That Arise from Contingencies" ("FSP FAS No. 141(R)-1"). FSP FAS No. 141(R)-1 requires that assets acquired and liabilities assumed in a business combination that arise from contingencies be recognized at fair value if fair value can be reasonably estimated. If fair value cannot be reasonably estimated, the assets or liabilities would generally be recognized in accordance with SFAS No. 5, "Accounting for Contingencies" ("SFAS No. 5") and FASB Interpretation No. 14, "Reasonable Estimation of the Amount of a Loss". Furthermore, the FASB removed the subsequent accounting guidance for assets and liabilities arising from contingencies from SFAS No. 141(R). FSP FAS No. 141(R)-1 also eliminates the requirement to disclose an estimate of the range of possible outcomes of recognized contingencies at the acquisition date. For unrecognized contingencies, the FASB requires that entities include only the disclosure required by SFAS No. 5. The Company will adopt FSP FAS No. 141(R)-1 during its second quarter ending July 5, 2009, and its effect on the Company's results of operation or financial position in future periods will depend on the nature and significance of any future business combination.

Note 2. New Accounting Pronouncements (Continued)

        In December 2007, the FASB issued SFAS No. 160, "Noncontrolling Interests in Consolidated Financial Statements" ("SFAS No. 160"), which establishes requirements for ownership interests in subsidiaries held by parties other than the Company (minority interests) to be clearly identified and disclosed in the consolidated statement of financial position within equity, but separate from the parent's equity. Any changes in the parent's ownership interests are required to be accounted for in a consistent manner as equity transactions and any noncontrolling equity investments in deconsolidated subsidiaries must be measured initially at fair value. SFAS No. 160 became effective on a prospective basis for fiscal years beginning after December 15, 2008; however, the presentation and disclosure requirements must be retrospectively applied to comparative financial statements. The Company adopted the provisions of SFAS No. 160 in its first quarter beginning January 1, 2009, and the adoption did not have any impact on its consolidated financial statements because the Company does not have any noncontrolling interests.

        In March 2008, the FASB issued SFAS No. 161, "Disclosures about Derivative Instruments and Hedging Activities" ("SFAS No. 161"), which amends SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities" ("SFAS No. 133"), and is intended to improve financial reporting related to derivative instruments and hedging activities by requiring enhanced disclosures to enable investors to better understand their effects on an entity's financial position, financial performance, and cash flows. The provisions of SFAS No. 161 became effective on a prospective basis for fiscal years beginning on or after November 15, 2008. The Company adopted the disclosure provisions of SFAS No. 161 during its first quarter beginning January 1, 2009. Since SFAS No. 161 requires only disclosures, there was no impact on the Company's consolidated financial statements; however, refer to Note 7 for the required disclosures.

        In April 2008, the FASB issued FSP FAS No. 142-3, "Determination of the Useful Life of Intangible Assets" ("FSP FAS No. 142-3"), which amends the factors an entity should consider in developing renewal or extension assumptions used in determining the useful life of recognized intangible assets under SFAS No. 142, "Goodwill and Other Intangible Assets". This new guidance applies prospectively to intangible assets that are acquired individually or with a group of other assets in business combinations and asset acquisitions. FSP FAS No. 142-3 became effective for financial statements issued for fiscal years and interim periods beginning after December 15, 2008. The Company adopted the provisions of FSP FAS No. 142-3 during its first quarter beginning January 1, 2009, and the adoption did not have any impact on its consolidated financial statements.

        In May 2008, the FASB issued SFAS No. 162, "The Hierarchy of Generally Accepted Accounting Principles" ("SFAS No. 162"), which identifies the sources of accounting principles and the framework for selecting principles to be used in the preparation and presentation of financial statements in accordance with United States generally accepted accounting principles. SFAS No. 162 will be effective 60 days after the SEC approves the Public Company Accounting Oversight Board's amendments to Interim Audit Standards Section 411, "The Meaning of Present Fairly in Conformity With Generally Accepted Accounting Principles". The Company will adopt the provisions and evaluate the impact of SFAS No. 162 upon its effective date.

        In December 2008, the FASB issued FSP FAS No. 132(R)-1, "Employers' Disclosures about Postretirement Benefit Plan Assets" ("FSP FAS No. 132(R)-1"), which provides additional guidance on an employers' disclosures about plan assets of a defined benefit pension or other post retirement plan. FSP FAS No. 132(R)-1 is effective for financial statements issued for fiscal years ending after

Note 2. New Accounting Pronouncements (Continued)

December 15, 2009. The Company will adopt the provisions of FSP FAS No. 132(R)-1 for its fiscal year beginning January 1, 2010, which will improve the disclosures in the financial statements related to the assets held by its defined pension and postretirement plans.

        In April 2009, the FASB issued FSP FAS No. 157-4, "Determining Fair Value When the Volume and Level of Activity for the Asset or Liability Have Significantly Decreased and Identifying Transactions That Are Not Orderly" ("FSP FAS No. 157-4"). According to the guidance, if an entity determines that the level of activity for an asset or liability has significantly decreased and that a transaction is not orderly, further analysis of the transaction or quoted prices is required, and a significant adjustment to the transaction or quoted prices may be deemed necessary to estimate the fair value in accordance with SFAS No. 157, "Fair Value Measurements" ("SFAS No. 157"). FSP FAS No. 157-4 is effective on a prospective basis for interim and annual periods ending after June 15, 2009 with early adoption permitted for periods ending after March 15, 2009. The Company will adopt the provisions of FSP FAS No. 157-4 for its second quarter ending July 5, 2009 and is currently evaluating the impact the provisions will have on its consolidated financial statements.

        In April 2009, the FASB issued FSP FAS No. 107-1 and Accounting Principles Board 28-1 "Interim Disclosures about Fair Value of Financial Instruments" ("FSP FAS No. 107-1"). FSP FAS No. 107-1 amends SFAS No. 107 "Disclosures about Fair Value of Financial Instruments" by requiring an entity to provide disclosures about fair value measurements of financial instruments in interim financial information. FSP FAS No. 107-1 is effective on a prospective basis for interim and annual periods ending after June 15, 2009 with early adoption permitted for periods ending after March 15, 2009. The Company will adopt the required disclosure provisions in its second quarter ending July 5, 2009. Since FSP FAS No. 107-1 only requires additional disclosures, there will be no impact on the Company's consolidated financial statements.

Note 3. Restructuring and Other Expenses

        The Company initiated a restructuring plan (the "2007 Restructuring Plan"), which it formulated in connection with the Company's acquisition of Elk. The 2007 Restructuring Plan was created to eliminate cost redundancies recognized due to the acquisition of Elk and to reduce the Company's current cost structure. The 2007 Restructuring Plan has been fully implemented as of December 31, 2008. The Company accounts for its restructuring activities in accordance with SFAS No. 146, "Accounting for Costs Associated with Exit or Disposal Activities", SFAS No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets" and Emerging Issues Task Force No. 96-9 "Classification of Inventory Markdowns and Other Costs Associated with Restructuring".

2008 Restructuring and Other Expenses

        In connection with the acquisition of Elk, the Company identified $64.1 million of restructuring and other expenses in its fiscal year ended December 31, 2008, which included $14.2 million of plant closing expenses, $3.3 million in employee severance payments and $46.6 million in integration-related expenses. Integration-related expenses primarily consisted of $26.9 million of inventory write-downs, $6.1 million of restructuring-related sales discounts and $13.6 million of other integration expenses.

        The Company recorded $73.2 million of the identified restructuring and other expenses in its statement of operations during its fiscal year ended December 31, 2008, of which $6.1 million was

reflected as a reduction in net sales due to restructuring-related sales discounts, $26.9 million was charged to cost of products sold and $40.2 million was charged to restructuring and other expenses.

Three-Months Ended April 5, 2009 Restructuring and Other Expenses

        In February 2009, the Company announced the temporary shutdown of two manufacturing facilities, one in Shafter, California and the other in Nashville, Tennessee. As a result of these actions and other charges related to the acquisition of Elk, the Company identified an additional $12.1 million of restructuring and other expenses in its first quarter ended April 5, 2009, which included $9.8 million of plant closing expenses, $0.9 million in employee severance payments and $1.4 million in integration-related expenses. Integration-related expenses primarily consisted of $0.8 million of inventory write-downs and $0.6 million of other integration expenses.

        The Company recorded $12.2 million of the identified restructuring and other expenses in its statement of operations in the three-month period ended April 5, 2009, of which $0.8 million was charged to cost of products sold and $11.4 million was charged to restructuring and other expenses. The Company expects to incur the remaining $1.7 million of identified integration and other expenses and make the remaining cash payments related to its accrual when they are required.

        The table below details the Company's restructuring and other expense accruals and charges made against the accrual during its first quarter ended April 5, 2009:

The Company anticipates funding these obligations principally from its cash and cash equivalents on hand, cash flow from operations and/or borrowings under its $600.0 million Senior Secured Revolving Credit Facility (the "Senior Secured Revolving Credit Facility").

        As of April 5, 2009, the Company was in compliance with all covenants under the Senior Secured Revolving Credit Facility, the $975.0 million Term Loan Facility (the "Term Loan"), the $325.0 million Junior Lien Term Loan Facility (the "Junior Lien Term Loan" and collectively with the Senior Secured Revolving Credit Facility and the Term Loan the "Senior Secured Credit Facilities") and the indenture governing its 7³/4% Senior Notes due 2014 (the "Senior Notes"). As of April 5, 2009, the net book value of the collateral securing the Senior Secured Revolving Credit Facility Collateral (as defined in the Senior Secured Revolving Credit Facility) and the Term Loan Collateral (as defined in the Term Loan) was $850.5 and $1,649.2 million, respectively.

        At April 5, 2009, the Company had outstanding letters of credit of approximately $43.8 million, which included approximately $10.6 million of standby letters of credit related to certain obligations of G-I Holdings.

Note 7. Derivative and Hedging Transactions

Hedging Strategy

        The Company is exposed to the impact of variable interest rate fluctuations on certain of its debt financings; however, the Company limits its variable interest rate exposure through the use of derivative instruments, which reduce the risk of interest rate fluctuations related to the Company's debt. As a result of the use of derivative instruments, the Company has exposure to the risk that its counterparties to derivative contracts will fail to meet their contractual obligations. In order to mitigate its

12

Note 7. Derivative and Hedging Transactions (Continued)

counterparty credit risk, the Company enters into derivative contracts with selected major financial institutions. The Company's policies and procedures for mitigating counterparty credit risk on derivative transactions include reviewing and establishing limits for credit exposure with each financial institution and a continuous assessment of the creditworthiness of each counterparty. The right of set-off that exists under certain of these derivative contracts enables the Company, subject to each derivative contract, to net amounts due to and from the counterparty reducing the maximum loss from credit risk in the event of counterparty default.

Interest Rate Swap Agreements

        In March 2007, the Company entered into forward-starting interest rate swap agreements ("swaps") with an effective date of April 23, 2007 and a maturity date of April 23, 2012. These swaps were initiated in order to hedge the variable interest rate risk associated with the Company's Term Loan, and they are structured that the Company receives interest based on the three-month Eurodollar rate ("LIBOR") and pay interest on a fixed rate basis. In October 2007, the Company entered into additional interest rate swaps related to its Term Loan with an effective date of October 23, 2007 and a maturity date of October 23, 2012 under similar terms.

        The Company accounts for its swaps in accordance with SFAS No. 133, and as such its swaps are treated as cash flow hedges. The Company values its interest rate swap agreements based on SFAS No. 157 Level 2 inputs from model-derived valuations whose significant inputs are quoted LIBOR contracts, Eurodollar futures and on-the-run swap markets. SFAS No. 157 requires that the valuation of derivative assets and liabilities must take into account the parties' nonperformance risk. The Company discounted the value of its derivative liabilities based on the credit spread for its debt as determined by the market trading price. See Note 8, Fair Value Measurements. As of April 5, 2009, the Company estimates that during the next twelve months ending March 2010, approximately $19.0 million will be reclassified from accumulated other comprehensive income/loss ("OCI") and recognized as interest expense in its statement of operations, subject to changes in the LIBOR rate. This estimated amount will be approximately offset by lower interest expense associated with the Company's Term Loan. Additional future amounts may be reclassified from OCI to interest expense if any portion of the Company's swaps are determined to be ineffective. As of April 5, 2009, the Company does not anticipate that any amount recorded in OCI related to its swaps will be reclassified during its next twelve months due to ineffectiveness.

Treasury Lock Agreements

        In July 2007, the Company entered into treasury lock agreements ("treasury locks") with a maturity date of July 31, 2012, as additional hedging instruments related to its Term Loan. On October 30, 2007, the Company settled its open treasury lock hedging positions, which resulted in a pre-tax fair value loss and cash settlement of approximately $4.9 million, which is being amortized into its statement of operations over the life of the Term Loan pursuant to the requirements of SFAS No. 133. The Company amortized $0.2 and $0.2 million of the loss related to its treasury locks into interest expense in its statement of operations during its first quarter ended April 5, 2009 and March 30, 2008, respectively, and will amortize $0.8 million annually through July 2012.

        As of April 5, 2009, the Company did not have any derivatives not designated as hedging instruments according to SFAS No. 133.

        On April 23, 2009, the Company exercised its option under the Term Loan to elect one-month LIBOR as the interest period under its LIBOR advances instead of the three-month interest period currently used for such advances. The change in election to the one-month LIBOR interest rate period resulted in a certain amount of ineffectiveness in the Company's current swap hedging agreements. During its second quarter ending July 5, 2009, the Company will begin to amortize the remaining amount of unrealized losses associated with these swap hedging agreements recorded in OCI at April 5, 2009, as a component of interest expense on a straight-line basis over the initial life of the swap agreements.

        During the quarter ended April 5, 2009, the Company adopted FSP FAS No. 157-2, "Partial Deferral to the Effective Date of Statement 157," which deferred the application of SFAS No. 157 for certain non-financial assets and non-financial liabilities. Upon adoption, the Company did not have any non-financial assets or liabilities that were recognized or measured at fair value on a recurring basis, therefore there was no impact on the Company's results of operations.

Note 9. Warranty Claims

        The Company provides certain limited warranties covering most of its residential roofing products for periods generally ranging from 20 to 50 years, although certain product lines provide for a lifetime limited warranty. The Company also offers certain limited warranties of varying duration covering most of its commercial roofing products. Most of the Company's specialty building products and accessories carry limited warranties for periods generally ranging from 5 to 20 years, with lifetime limited warranties on certain products.

        The accrual for product warranty claims consists of the following for the first quarter ended April 5, 2009 and March 30, 2008, respectively:

	April 5, 2009			March 30, 2008
	(Thousands)
Beginning Balance	$	44,965		$	44,724
Charged to cost of products sold		7,507			4,765
Payments/deductions		(4,521	)		(3,174	)
Ending Balance	$	47,951		$	46,315

        The Company offers extended warranty contracts on sales of its commercial roofing products. The life of these commercial warranties range from 10 to 25 years. In addition, the Company offers enhanced warranties on certain of its residential roofing products. These enhanced warranties are the "Golden Pledge™" and "Peace of Mind™" warranty programs. All revenue for the sale of these

warranty programs is deferred and amortized on a straight-line basis over the average life of these warranty programs, which is in accordance with the accounting prescribed by FASB Technical Bulletin No. 90-1 "Accounting for Separately Priced Extended Warranty and Product Maintenance Contracts". Incremental direct costs associated with the acquisition of the extended warranty contracts are capitalized and amortized on a straight-line basis over the average life of these warranty programs. Current costs of services performed related to claims paid under these warranty programs are expensed as incurred. The analysis of these warranty programs as of April 5, 2009 indicated that deferred revenue is in excess of deferred costs and accordingly, no loss was recognized. However, if the total expected costs of providing services under these warranty programs exceed deferred revenues less deferred costs, then a loss would be recognized.

        At April 5, 2009 and March 30, 2008, the Company had deferred revenue of $78.2 and $71.5 million, of which $10.9 and $8.6 million is included in other current liabilities and $67.3 and $62.9 million is included in other liabilities, respectively. At April 5, 2009 and March 30, 2008, the Company also had deferred costs of $54.0 and $49.1 million, of which $7.2 and $5.5 million is included in other current assets and $46.8 and $43.6 million is included in other assets, respectively.

Note 10. Benefit Plans

Defined Benefit Plans

        The Company provides a noncontributory defined benefit retirement plan for certain hourly and salaried employees (the "Retirement Plan"). Benefits under this plan are based on stated amounts for each year of service. The Company's funding policy is consistent with the minimum funding requirements of the Employee Retirement Income Security Act of 1974.

        The Company's net periodic pension cost for the Retirement Plan included the following components for the first quarter ended April 5, 2009 and March 30, 2008, respectively:

	April 5, 2009			March 30, 2008
	(Thousands)
Service cost	$	351		$	430
Interest cost		642			611
Expected return on plan assets		(792	)		(792	)
Amortization of unrecognized prior service cost		2			3
Amortization of net losses from earlier periods		180			105
Net periodic pension cost	$	383		$	357

        As of April 5, 2009, the Company expected to make pension contributions of $4.2 million to the Retirement Plan in 2009, which is consistent with its expectations as of December 31, 2008. The Company made a Retirement Plan contribution of $0.3 million during the first quarter ended April 5, 2009.

Postretirement Medical and Life Insurance

        The Company generally does not provide postretirement medical and life insurance benefits, although it subsidizes such benefits for certain employees and retirees. Such subsidies were reduced or

ended as of January 1, 1997. Effective March 1, 2005, the Company amended the plan eliminating postretirement medical benefits affecting all current and future retirees.

        Net periodic postretirement benefit included the following components for the first quarter ended April 5, 2009 and March 30, 2008, respectively:

	April 5, 2009			March 30, 2008

Net periodic postretirement benefit	$	(166	)	$	(167	)

        As of April 5, 2009, the Company expected to make aggregate benefit claim payments of approximately $0.2 million during 2009, which are related to postretirement life insurance expenses. This is consistent with the Company's expectations as of December 31, 2008.

Note 11. 2001 Long-Term Incentive Plan

        Incentive units granted under the 2001 Long-Term Incentive Plan (the "2001 LTIP") are valued at Book Value (as defined in the 2001 LTIP) or the value of such incentive units specified at the date of grant. Increases or decreases in the Book Value of those incentive units result in a change in the measure of compensation for the award. Compensation expense for the Company's incentive units was $7.0 and $0.4 million for the first quarter ended April 5, 2009 and March 30, 2008, respectively.

        The following is a summary of activity for incentive units related to the 2001 LTIP:

	First Quarter April 5, 2009			Year-to-Date December 31, 2008
Incentive Units outstanding, beginning of period		90,468			99,120
Granted		725			17,375

Incentive Units outstanding, end of period		84,993			90,468
Vested Units outstanding, end of period		39,030			33,702

        The initial value of each of the 725 incentive units granted on January 1, 2009 was $706.88. The initial value of each of the 17,000 incentive units granted on January 1, 2008 was $592.01 and the 375 incentive units granted on October 1, 2008 was $687.97.

Note 12. Related Party Transactions

        The Company makes loans to, and borrows from, its parent corporations from time to time at prevailing market interest rates. At April 5, 2009 and March 30, 2008, BMCA Holdings Corporation

17

BUILDING MATERIALS CORPORATION OF AMERICA

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) (Continued)

Note 12. Related Party Transactions (Continued)

owed the Company $56.4 and $56.3 million, including interest of $1.1 and $1.0 million, respectively, and the Company owed BMCA Holdings Corporation $52.8 and $52.8 million, respectively, with no unpaid interest. Interest income on the Company's loans to BMCA Holdings Corporation amounted to $0.6 and $1.0 million during the first quarter ended April 5, 2009 and March 30, 2008, respectively. Interest expense on the Company's loans from BMCA Holdings Corporation amounted to $0.6 and $1.0 million during the first quarter ended April 5, 2009 and March 30, 2008, respectively. Loans payable to/receivable from its parent corporations are due on demand and provide each party with the right of offset of its related obligation to the other party and are subject to limitations as outlined in the Senior Secured Credit Facilities and the Senior Notes. Under the terms of the Senior Secured Revolving Credit Facility and the indenture governing the Company's Senior Notes at April 5, 2009, the Company could repay demand loans to its parent corporation amounting to $52.8 million, subject to certain conditions.

        The Company has a management agreement (the "Management Agreement") with ISP Management Company, Inc., a subsidiary of International Specialty Products Inc. (which, together with its subsidiaries, is referred to as "ISP"), an affiliate, to provide the Company with certain management services. Based on services provided to the Company in 2009 under the Management Agreement, the aggregate amount payable to ISP Management Company, Inc. under the Management Agreement for 2009, inclusive of the services provided to G-I Holdings, is not yet available; however, after adjusting for inflationary factors, it is currently estimated to be similar to the $7.3 million paid in 2008. The Company does not expect any changes to the Management Agreement to have a material impact on the Company's results of operations.

        The Company and its subsidiaries purchased a substantial portion of their headlap roofing granules, colored roofing granules and algae-resistant granules, on a purchase order basis, from ISP Minerals Inc. ("ISP Minerals"), an affiliate of BMCA and of ISP. The amount of mineral products purchased each year on this basis is based on current demand and is not subject to minimum purchase requirements. For the first quarter ended April 5, 2009 and March 30, 2008, the Company and its subsidiaries purchased $11.5 and $7.2 million, respectively, of roofing granules under this arrangement.

        In addition to the granules products purchased by the Company, under the above purchase order basis, the balance of its granules requirements are purchased under a contract expiring in 2013. The amount of mineral products purchased each year under the contract is based on current demand and is not subject to minimum purchase requirements. Under the contract, for the first quarter ended April 5, 2009 and March 30, 2008, the Company purchased $18.2 and $19.1 million of roofing granules, respectively.

        In February 2009 and March 2009, after giving effect to the most restrictive of the aforementioned debt covenant restrictions, the Company declared and paid cash dividends of $5.0 and $5.0 million, respectively, to its parent corporation.

        Included in noncurrent assets as a tax receivable from parent corporation on the Company's consolidated balance sheets is $0.0 and $8.4 million at April 5, 2009 and December 31, 2008, respectively, representing amounts paid in excess of amounts due to G-I Holdings with respect to 2006 under the Tax Sharing Agreement. The Company utilized the remaining receivable balance at December 31, 2008 during its first quarter ended April 5, 2009. These amounts are included in the net payable to related parties/parent corporations in the consolidated statements of cash flows.

Note 13. Contingencies

        In connection with its formation, the Company contractually assumed and agreed to pay the first $204.4 million of liabilities of its indirect parent, G-I Holdings, for asbestos-related bodily injury claims relating to the inhalation of asbestos fiber contained in products sold by G-I Holdings or its predecessors ("Asbestos Claims"). As of March 30, 1997, the Company paid all of its assumed liabilities for Asbestos Claims. G-I Holdings has agreed to indemnify the Company against any other existing or future Asbestos Claims if asserted against the Company. In January 2001, G-I Holdings filed a voluntary petition for reorganization under Chapter 11 of the U.S. Bankruptcy Code due to Asbestos Claims. Most Asbestos Claims do not specify the amount of damages sought, and the value of the Asbestos Claims asserted against G-I Holdings is a contested issue in that bankruptcy, which remains pending.

        Claimants in the G-I Holdings' bankruptcy, including judgment creditors, might seek to satisfy their claims by asking the Bankruptcy Court to require the sale of G-I Holdings' assets, including its holdings of BMCA Holdings Corporation's common stock and its indirect holdings of the Company's common stock. Such action could result in a change of control of the Company. In addition, those creditors may attempt to assert Asbestos Claims against the Company. (Approximately 1,900 Asbestos Claims were filed against the Company prior to February 2, 2001.) The Company believes that it will not sustain any liability in connection with these or any other Asbestos Claims. On February 2, 2001, the United States Bankruptcy Court for the District of New Jersey issued a temporary restraining order enjoining any existing or future claimant from bringing or prosecuting an Asbestos Claim against the Company. By oral opinion on June 22, 2001, and written order entered February 22, 2002, the Bankruptcy Court converted the temporary restraints into a preliminary injunction prohibiting the bringing or prosecution of any such Asbestos Claims against the Company.

        On February 7, 2001, G-I Holdings filed an action in the United States Bankruptcy Court for the District of New Jersey seeking a declaratory judgment that BMCA has no successor liability for Asbestos Claims against G-I Holdings and that it is not the alter ego of G-I Holdings (the "BMCA Action"). One of the parties to this matter, the Official Committee of Asbestos Claimants (the "creditors' committee"), subsequently filed a counterclaim against the Company seeking a declaration that BMCA has successor liability for Asbestos Claims against G-I Holdings and that it is the alter ego of G-I Holdings. On May 13, 2003, the United States District Court for the District of New Jersey overseeing the G-I Holdings' Bankruptcy Court withdrew the reference of the BMCA Action from the Bankruptcy Court. By order dated May 30, 2008, the District Court dismissed the BMCA Action without ruling on the merits of BMCA's position that it has no successor liability for Asbestos Claims. The District Court ruled that a Federal court declaratory judgment action was not the proper vehicle for resolving this issue. The District Court's ruling did not affect the preliminary injunction enjoining the prosecution of Asbestos Claims against BMCA, and the Company believes that it does not have liability for Asbestos Claims. Nevertheless, it is not possible to predict the outcome of any subsequent litigation regarding the continuation of the preliminary injunction and/or prosecution of Asbestos Claims against the Company.

Note 13. Contingencies (Continued)

        On or about February 8, 2001, the creditors' committee filed a complaint in the United States Bankruptcy Court, District of New Jersey against G-I Holdings and the Company. The complaint requests substantive consolidation of BMCA with G-I Holdings or an order directing G-I Holdings to cause BMCA to file for bankruptcy protection. The plaintiffs also filed for interim relief absent the granting of their requested relief described above. On March 21, 2001, the Bankruptcy Court denied plaintiffs' application for interim relief. In November 2002, the creditors' committee, joined in by the legal representative of present and future holders of asbestos-related claims, filed a motion for appointment of a trustee in the G-I Holdings' bankruptcy. In December 2002, the Bankruptcy Court denied the motion. The creditors' committee appealed the ruling to the United States District Court, which denied the appeal on June 27, 2003. The creditors' committee appealed the denial to the Third Circuit Court of Appeals, which denied the appeal on September 24, 2004. The creditors' committee filed a petition with the Third Circuit Court of Appeals for a rehearing of its denial of the creditors' committee's appeal, which was denied by the Court of Appeals on October 26, 2004.

        On July 7, 2004, the Bankruptcy Court entered an order authorizing the creditors' committee to commence an adversary proceeding against the Company and others challenging, as a fraudulent conveyance, certain transactions entered into in connection with the Company's formation in 1994, in which G-I Holdings caused to be transferred to the Company all of its roofing business and assets and in which the Company assumed certain liabilities relating to those assets, including a specified amount of liabilities for Asbestos Claims (the "1994 transaction"). The Bankruptcy Court also permitted the creditors' committee to pursue a claim against holders of the Company's bank and bond debt outstanding in 2000, seeking recovery from them, based on the creditors' committee's theory that the 1994 transaction was a fraudulent conveyance. On July 20, 2004, the creditors' committee appealed certain aspects of the Bankruptcy Court's order (and a June 8, 2004 decision upon which the order was based). G-I Holdings, the holders of the Company's bank and bond debt and BMCA cross-appealed. The District Court entered an order on June 21, 2006 affirming in part and vacating in part the Bankruptcy Court's July 7, 2004 order. Among other things, the District Court vacated that aspect of the Bankruptcy Court's order authorizing the creditors' committee to pursue avoidance claims against the Company and the holders of the Company's bank and bond debt as of 2000. This issue has been remanded to the Bankruptcy Court for further proceedings consistent with the District Court's opinion. By order dated August 22, 2008, the Bankruptcy Court stayed this authorization proceeding and other adversary proceedings effective upon the filing of a Joint Plan of Reorganization by G-I Holdings, the creditors' committee and the legal representative of present and future holders of asbestos-related claims. The Company believes the creditors' committee's avoidance claims are without merit and, in the event the stay is terminated, the Bankruptcy Court should not permit the creditors' committee to pursue such claims against the Company and the holders of its bank and bond debt as of 2000.

        The Company has been advised by G-I Holdings that on August 12, 2008, G-I Holdings reached an agreement with the creditors' committee and the legal representative of present and future holders of asbestos-related claims to jointly file a plan of reorganization with the Bankruptcy Court that will provide for settlement of Asbestos Claims and all related litigation. The agreement is subject to a number of contingencies, but if the contingencies are met and the reorganization plan is confirmed, all of the actions described above will be resolved. If the bankruptcy is not resolved, the Company and G-I Holdings intend to vigorously defend all litigations related thereto. A Joint Plan of Reorganization of G-I Holdings was filed with the Bankruptcy Court on August 21, 2008, and a First Amended Joint Plan of Reorganization of G-I Holdings was filed with the Bankruptcy Court on October 30, 2008.

Note 13. Contingencies (Continued)

G-I Holdings filed a Second Amended Joint Plan of Reorganization of G-I Holdings with the Bankruptcy Court on December 3, 2008.

        If the reorganization plan is not confirmed and the Company is not successful in defending against one or more of the claims, it may be forced to file for bankruptcy protection and/or contribute all or a substantial portion of its assets to satisfy the claims of G-I Holdings' creditors. Either of these events, or the substantive consolidation of G-I Holdings and the Company, would weaken its operations and cause it to divert a material amount of its cash flow to satisfy the Asbestos Claims of G-I Holdings and may render it unable to pay interest or principal on its Senior Secured Credit Facilities and Senior Notes.

Tax Claims Against G-I Holdings

        On September 15, 1997, G-I Holdings received a notice from the Internal Revenue Service (the "IRS") of a deficiency in the amount of $84.4 million (after taking into account the use of net operating losses and foreign tax credits otherwise available for use in later years) in connection with the formation in 1990 of Rhône-Poulenc Surfactants and Specialties, L.P. (the "surfactants partnership"), a partnership in which G-I Holdings held an interest. On September 21, 2001, the IRS filed a proof of claim with respect to such deficiency against G-I Holdings in the G-I Holdings' bankruptcy. If such proof of claim is sustained for years in which the Company was part of the G-I Holdings tax group, the Company and/or certain of the Company's subsidiaries together with G-I Holdings and several current and former subsidiaries of G-I Holdings could be severally liable for those taxes and interest. G-I Holdings has filed an objection to the proof of claim, which is the subject of an adversary proceeding pending in the United States District Court for the District of New Jersey. By opinion and order dated September 8, 2006, the District Court ruled on the parties' respective motions for Partial Summary Judgment, granting the government summary judgment on the issue of "adequate disclosure" for statute of limitation purposes and denying G-I Holdings summary judgment on its other statute of limitations defense (finding material issues of fact that must be tried). If the IRS were to prevail for the years in which the Company and/or certain of its subsidiaries were not part of the G-I Holdings tax group, the Company nevertheless could be liable for approximately $40.0 million in taxes plus interest, although this calculation is subject to uncertainty depending upon various factors including G-I Holdings' ability to satisfy its tax liabilities and the application of tax credits and deductions. In an opinion dated June 8, 2007, the District Court decided that G-I Holdings cannot avail itself of the "binding contract" transitional relief with respect to the 1999 distribution of U.S. Treasury Bonds to G-I Holdings. The Company believes that it will not be required to pay any incremental income tax to the Federal government with respect to this matter and that its ultimate disposition will not have a material adverse effect on its business, financial position or results of operations.

Environmental Litigation

        The Company, together with other companies, is a party to a variety of proceedings and lawsuits involving environmental matters under the U.S. Comprehensive Environmental Response Compensation and Liability Act, and similar state laws, in which recovery is sought for the cost of

cleanup of contaminated sites or remedial obligations are imposed, a number of which are in the early stages or have been dormant for protracted periods. Most of these environmental claims do not seek to recover an amount of specific damages. At most sites, the Company anticipates that liability will be apportioned among the companies found to be responsible for the presence of hazardous substances at the site.

        While the Company cannot predict whether adverse decisions or events can occur in the future, the Company believes that the ultimate disposition of such matters will not have a material adverse effect on the liquidity, results of operations, cash flows or financial position of the Company.

Other Contingencies

        In the ordinary course of business, the Company has several supply agreements that include minimum annual purchase requirements. In the event these purchase requirements are not met, the Company may be required to make payments under these supply agreements. There have been no material changes to these contracts in the first quarter of 2009.

Note 14. Guarantor Financial Information

        At April 5, 2009, all of the Company's subsidiaries, each of which is wholly-owned by the Company, are guarantors under the Company's Senior Secured Credit Facilities and the indenture governing the Senior Notes. These guarantees are full, unconditional and joint and several. In 2007, BMCA Acquisition Inc., the direct parent of Elk, and Elk, as a result of its merger with BMCA Acquisition Sub, became co-obligors on the Senior Secured Credit Facilities.

        Presented below is condensed consolidating financial information for the Company, the co-obligor subsidiary and the guarantor subsidiaries. This financial information should be read in conjunction with the consolidated financial statements and other notes related thereto. Separate financial statements for the Company and the guarantor subsidiaries are not included herein, because the guarantees are full, unconditional and joint and several.

BUILDING MATERIALS CORPORATION OF AMERICA

Item 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS

        We are a leading national manufacturer and marketer of a broad line of asphalt and polymer-based roofing products and accessories for the residential and commercial roofing markets. During the first quarter of 2007, Building Materials Corporation of America, which we refer to as BMCA, acquired ElkCorp, which we refer to as Elk, a Dallas, Texas-based manufacturer of roofing products and building materials, resulting in Elk becoming an indirect wholly-owned subsidiary of BMCA.

        We believe the Elk acquisition has strategically positioned us for growth in the roofing industry and building products market and has allowed us to build on our market leadership position and create comprehensive market-leading product offerings. Our principal lines of residential roofing shingles are the Timberline® series, the Sovereign® series, Designer Lifetime Shingles and Specialty Shingles. The Timberline series includes the Timberline Prestique® 30 High Definition®, Timberline Natural Shadow™, Timberline Prestique 40, Timberline Prestique Lifetime and Timberline Prestique Grande® shingles. Our designer lifetime shingles include the Slateline®, Grand Slate™, Grand Sequoia®, Grand Canyon™, Country Mansion®, Capstone®, and Camelot® shingles. We sell specialty roofing products under the TruSlate™ product line, which offers a patented genuine slate roofing system. We supply the major components necessary to install a complete roofing system from underlayments to attic ventilation products and accessories, under our Roof System Solution. We have improved our sales mix of residential roofing products by increasing our emphasis on laminated shingles and accessory products (the Timberline series, designer lifetime shingles and TruSlate), which are generally sold at higher prices and more attractive profit margins than our standard strip shingle products (the Sovereign series). Unless otherwise indicated by the context, "we," "us," and "our" refer to Building Materials Corporation of America and its consolidated subsidiaries.

Critical Accounting Policies

        There have been no significant changes to our Critical Accounting Policies during the first quarter ended April 5, 2009. For a further discussion on our Critical Accounting Policies, reference is made to Management's Discussion and Analysis of Financial Condition and Results of Operations, "Critical Accounting Policies" in our annual report on Form 10-K for the fiscal year ended December 31, 2008, which was filed with the Securities and Exchange Commission on March 31, 2009, which we refer to as the 2008 Form 10-K.

Results of Operations

        Roofing products sales is our dominant business, typically accounting for approximately 95% of our consolidated net sales. The main drivers of our roofing business include: the nation's aging housing stock; existing home sales; new home construction; larger new homes; home ownership rates; and extreme weather and energy concerns. Our roofing business is also affected by raw material costs, including asphalt and other petroleum-based raw materials, as well as energy, and transportation and distribution costs.

First Quarter 2009 Compared With First Quarter 2008

        We recorded net income of $52.0 million in the first quarter of 2009 compared to a net loss of $15.0 million in the first quarter of 2008. Our reported net income in the first quarter of 2009 included $7.9 million after-tax ($12.2 million pre-tax) restructuring and other expenses, of which $0.5 million after-tax ($0.8 million pre-tax) was included in cost of products sold. Our reported net loss in the first quarter of 2008 included $16.9 million of after-tax ($28.0 million pre-tax) restructuring and other expenses, of which $0.7 million after-tax ($1.1 million pre-tax) was included as a reduction in net sales

RESULTS OF OPERATIONS (Continued)

and $3.7 million after-tax ($6.1 million pre-tax) was included in cost of products sold. Included in restructuring and other expenses for the first quarter of 2008 and 2009 are plant closing expenses related to the closure of several manufacturing facilities, integration-related costs and the write-down of selected inventories. Excluding restructuring and other expenses, first quarter of 2009 net income was $59.9 million compared to first quarter of 2008 net income of $1.9 million. The increase in reported net income for the first quarter of 2009 was primarily attributable to higher income before interest expense and income taxes and lower interest expense.

        Net sales for the first quarter of 2009 were $660.8 million compared to first quarter of 2008 net sales of $570.3 million, which included $1.1 million of restructuring-related sales discounts. The increase in first quarter of 2009 net sales was primarily due to higher average selling prices for residential and commercial roofing products, partially offset by lower unit volumes of residential and commercial roofing products.

        Income before interest expense and income taxes in the first quarter of 2009 was $114.3 million compared to income before interest expense and income taxes of $14.9 million in the first quarter of 2008. Our reported income before interest expense and income taxes in the first quarter of 2009 included $12.2 million of restructuring and other expenses, of which $0.8 million was included in cost of products sold. Our reported income before interest expense and income taxes for the first quarter of 2008 included $28.0 million of restructuring and other expenses, of which $1.1 million was included as a reduction in net sales and $6.1 million was included in cost of products sold. Excluding these items, first quarter of 2009 income before interest expense and income taxes was $126.5 million compared to first quarter of 2008 income before interest expense and income taxes of $42.9 million. The increase was primarily due to higher average selling prices of residential and commercial roofing products, lower manufacturing costs resulting from improved efficiencies and lower transportation costs. These benefits were partially offset by lower unit volumes of residential and commercial roofing products.

        Interest expense in the first quarter of 2009 decreased to $34.5 million compared to $39.9 million in the first quarter of 2008. The decrease in the first quarter of 2009 interest expense was primarily due to lower average borrowings and a lower average interest rate.

Business Segment Information

Net Sales.    Net sales of roofing products increased to $635.0 million for the first quarter of 2009, compared with $537.6 million for the first quarter of 2008, which included $1.1 million of restructuring-related sales discounts. The increase in first quarter of 2009 net sales was primarily due to higher average selling prices of residential and commercial roofing products, partially offset by lower unit volumes of residential and commercial roofing products. Net sales of specialty building products and accessories decreased to $25.8 million for the first quarter of 2009 compared with $32.7 million for the first quarter of 2008 due to softer new construction and remodeling demand.

Gross Margin.    Our gross margin was $231.4 million or 35.0% of net sales for the first quarter of 2009 compared with $145.4 million or 25.5% of net sales for the first quarter of 2008. Included in our gross margin for the first quarter of 2009 were $0.8 million of restructuring and other expenses, which was included in cost of products sold. Included in our gross margin for the first quarter of 2008 were $7.2 million of restructuring and other expenses, of which $1.1 million was included as a reduction in net sales and $6.1 million was included in cost of products sold. The increase in our gross margin is primarily due to higher average selling prices of residential and commercial roofing products, as well as

lower manufacturing costs resulting from improved efficiencies, partially offset by lower unit volumes of residential and commercial roofing products.

Liquidity and Financial Condition

Cash Flows and Cash Position

        Sales of roofing products and specialty building products and accessories in the northern regions of the United States generally decline in the late fall and winter months due to cold weather. In addition, extreme weather conditions can result in higher customer demand during our peak operating season depending on the extent and severity of the damage from these extreme weather conditions. Due to the seasonal demands of our business, together with extreme weather conditions, we generally have negative cash flows from operations during the first six months of our fiscal year. Our negative cash flows from operations are primarily driven by our cash invested in both accounts receivable and inventories to meet these seasonal operating demands. Generally, in the third and fourth quarters of our fiscal year, our cash flows from operations become positive for each quarter, as our investment in inventories and accounts receivable no longer continues to increase, as is customary in the first six months of our fiscal year. Our seasonal working capital needs, together with our debt service obligations, capital expenditure requirements and other contracted arrangements, adversely impact our liquidity during this period. We rely on our cash and cash equivalents on hand and our $600.0 million Senior Secured Revolving Credit Facility due February 2012, which we refer to as our Senior Secured Revolving Credit Facility (see Long-Term Debt), to support our overall cash flow requirements during these periods. We expect to continue to rely on our cash and cash equivalents on hand and external financings to maintain operations over the short and long-term and to continue to have access to the financing markets, subject to the then prevailing market terms and conditions.

        Net cash outflow from operating and investing activities was $101.8 million during the first quarter of 2009, including $91.8 million of cash used in operations and the reinvestment of $10.0 million for capital programs.

        Cash invested in additional working capital totaled $210.2 million during the first quarter of 2009, reflecting an increase in total accounts receivable of $249.4 million, due to the seasonality of our business, a $61.2 million decrease in inventories primarily due to controlled inventory management due to the current worldwide economic conditions, a $3.2 million decrease in other current assets, a $16.4 million decrease in accounts payable and accrued liabilities and an increase of $8.8 million in payments for restructuring and other expenses. The net cash used in operating activities also included a $23.5 million net increase in the payable to related parties/parent corporations, primarily due to a net $20.1 million increase in Federal income taxes payable, pursuant to our Tax Sharing Agreement with our parent corporation and a $3.4 million increase in amounts due under our long-term granule supply agreement with an affiliated company. In addition, net cash used in operating activities included $12.2 million in restructuring and other expenses (see Restructuring and Other Expenses below).

        Net cash provided by financing activities totaled $89.8 million during the first quarter of 2009, including $233.0 million of aggregate proceeds from the issuance of long-term debt, related to first quarter of 2009 cumulative borrowings under our Senior Secured Revolving Credit Facility. Financing activities also included $129.5 million in aggregate repayments of long-term debt, of which $126.0 million related to first quarter of 2009 cumulative repayments under our Senior Secured Revolving Credit Facility and $2.4 million related to our $975.0 million Term Loan Facility, which we refer to as the Term Loan. In addition, financing activities included aggregate principal payments of

31

Item 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS (Continued)

$3.5 million on our capital leases, $10.0 million of cash dividends paid to our parent corporation, and $0.2 million in financing fees and expenses primarily related to prior debt refinancings.

Restructuring and Other Expenses

        We initiated a restructuring plan, which we refer to as the 2007 Restructuring Plan, which we formulated in connection with the acquisition of Elk. The 2007 Restructuring Plan was created to eliminate cost redundancies recognized due to the acquisition of Elk and to reduce our current cost structure. The 2007 Restructuring Plan has been fully implemented as of December 31, 2008. We account for our restructuring activities in accordance with SFAS No. 146, "Accounting for Costs Associated with Exit or Disposal Activities", SFAS No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets" and Emerging Issues Task Force No. 96-9 "Classification of Inventory Markdowns and Other Costs Associated with Restructuring".

2008 Restructuring and Other Expenses

        In connection with the acquisition of Elk, we identified $64.1 million of restructuring and other expenses in our fiscal year ended December 31, 2008, which included $14.2 million of plant closing expenses, $3.3 million in employee severance payments and $46.6 million in integration-related expenses. Integration-related expenses primarily consisted of $26.9 million of inventory write-downs, $6.1 million of restructuring-related sales discounts and $13.6 million of other integration expenses.

        We recorded $73.2 million of the identified restructuring and other expenses in our statement of operations during our fiscal year ended December 31, 2008, of which $6.1 million was reflected as a reduction in net sales due to restructuring-related sales discounts, $26.9 million was charged to cost of products sold and $40.2 million was charged to restructuring and other expenses.

Three-Months Ended April 5, 2009 Restructuring and Other Expenses

        In February 2009, we announced the temporary shutdown of two manufacturing facilities, one in Shafter, California and the other in Nashville, Tennessee. As a result of these actions and other charges related to the acquisition of Elk, we identified an additional $12.1 million of restructuring and other expenses in our first quarter ended April 5, 2009, which included $9.8 million of plant closing expenses, $0.9 million in employee severance payments and $1.4 million in integration-related expenses. Integration-related expenses primarily consisted of $0.8 million of inventory write-downs and $0.6 million of other integration expenses.

        We recorded $12.2 million of the identified restructuring and other expenses in our statement of operations in the three-month period ended April 5, 2009, of which $0.8 million was charged to cost of products sold and $11.4 million was charged to restructuring and other expenses. We expect to incur the remaining $1.7 million of identified integration and other expenses and make the remaining cash payments related to our accrual when they are required.

        As of April 5, 2009, we had total outstanding consolidated indebtedness of $1,831.7 million, which included $52.8 million of demand loans to our parent corporation and $20.8 million that matures prior to the end of the first quarter of 2010. We anticipate funding these obligations principally from our cash and cash equivalents on hand, cash flow from operations and/or borrowings under our Senior Secured Revolving Credit Facility.

        As of April 5, 2009, we were in compliance with all covenants under the Senior Secured Revolving Credit Facility, the Term Loan, the $325.0 million Junior Lien Term Loan Facility, which we refer to as the Junior Lien Term Loan, and collectively with the Senior Secured Revolving Credit Facility and the Term Loan we refer to as the Senior Secured Credit Facilities; and the indenture governing our 7³/4% Senior Notes due 2014, which we refer to as the Senior Notes. As of April 5, 2009, the net book value of the collateral securing the Senior Secured Revolving Credit Facility Collateral (as defined in the

33

Senior Secured Revolving Credit Facility) and the Term Loan Collateral (as defined in the Term Loan) was $850.5 and $1,649.2 million, respectively.

        At April 5, 2009, we had outstanding letters of credit of approximately $43.8 million, which included approximately $10.6 million of standby letters of credit related to certain obligations of G-I Holdings.

Derivative and Hedging Transactions

Hedging Strategy

        We were exposed to the impact of variable interest rate fluctuations on certain of our debt financings; however, we limit our variable interest rate exposure through the use of derivative instruments, which reduce the risk of interest rate fluctuations related to our debt. As a result of the use of derivative instruments, we have exposure to the risk that our counterparties to derivative contracts will fail to meet their contractual obligations. In order to mitigate our counterparty credit risk, we enter into derivative contracts with selected major financial institutions. Our policies and procedures for mitigating counterparty credit risk on derivative transactions include reviewing and establishing limits for credit exposure with each financial institution and a continuous assessment of the creditworthiness of each counterparty. The right of set-off that exists under certain of these derivative contracts enables us, subject to each derivative contract, to net amounts due to and from the counterparty reducing the maximum loss from credit risk in the event of counterparty default.

Interest Rate Swap Agreements

        In March 2007, we entered into forward-starting interest rate swap agreements, which we refer to as swaps, with an effective date of April 23, 2007 and a maturity date of April 23, 2012. These swaps were initiated in order to hedge the variable interest rate risk associated with our Term Loan, and they are structured that we receive interest based on the three-month LIBOR and pay interest on a fixed rate basis. In October 2007, we entered into additional interest rate swaps related to our Term Loan with an effective date of October 23, 2007 and a maturity date of October 23, 2012 under similar terms.

        We account for our swaps in accordance with "Accounting for Derivative Instruments and Hedging Activities", which we refer to as SFAS No. 133, and as such our swaps are treated as cash flow hedges. We value our interest rate swap agreements based on SFAS No. 157 "Fair Value Measurements", which we refer to as SFAS No. 157, Level 2 inputs from model-derived valuations whose significant inputs are quoted LIBOR contracts, Eurodollar futures and on-the-run swap markets. SFAS No. 157 requires that the valuation of derivative assets and liabilities must take into account the parties' nonperformance risk. We discounted the value of our derivative liabilities based on the credit spread for our debt as determined by the market trading price. See Fair Value Measurements. As of April 5, 2009, we estimate that during the next twelve months ending March 2010, approximately $19.0 million will be reclassified from accumulated other comprehensive income/loss, which we refer to as OCI, and recognized as interest expense in our statement of operations, subject to changes in the LIBOR rate. This estimated amount will be approximately offset by lower interest expense associated with our Term Loan. Additional future amounts may be reclassified from OCI to interest expense if any portion of our swaps are determined to be ineffective. As of April 5, 2009, we do not anticipate that any amount recorded in OCI related to our swaps will be reclassified during the next twelve months due to ineffectiveness.

Treasury Lock Agreements

        In July 2007, we entered into treasury lock agreements, which we refer to as treasury locks, with a maturity date of July 31, 2012, as additional hedging instruments related to our Term Loan. On October 30, 2007, we settled our open treasury lock hedging positions, which resulted in a pre-tax fair value loss and cash settlement of approximately $4.9 million, which is being amortized into our statement of operations over the life of the Term Loan pursuant to the requirements of SFAS No. 133. We amortized $0.2 and $0.2 million of the loss related to our treasury locks into interest expense in our statement of operations during our first quarter ended April 5, 2009 and March 30, 2008, respectively, and will amortize $0.8 million annually through July 2012.

        The following table sets forth the classification and fair values of our derivative instruments at April 5, 2009:

FAIR VALUE OF DERIVATIVE INSTRUMENTS
(Millions)

Description		Balance Sheet Classification	Fair Value
Derivatives designated as hedging instruments under SFAS No. 133:
	Fixed-income interest rate swap agreements	Other non-current liabilities	$	70.6

        The amount included in OCI, net of tax, related to our derivative liability at April 5, 2009 and December 31, 2008 was $43.8 and $43.7 million, respectively.

        The following table sets forth the effect of our derivative instruments on financial performance for the first quarter ended April 5, 2009:

        As of April 5, 2009, we did not have any derivatives not designated as hedging instruments according to SFAS No. 133.

        On April 23, 2009, we exercised our option under the Term Loan to elect one-month LIBOR as the interest period under its LIBOR advances instead of the three-month interest period currently used

35

BUILDING MATERIALS CORPORATION OF AMERICA

Item 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS (Continued)

for such advances. The change in election to the one-month LIBOR interest rate period resulted in a certain amount of ineffectiveness in our current swap hedging agreements. During our second quarter ending July 5, 2009, we will begin to amortize the remaining amount of unrealized losses associated with our swap hedging agreements recorded in OCI at April 5, 2009, as a component of interest expense on a straight-line basis over the initial life of the swap agreements.

Fair Value Measurements

        The following table sets forth information regarding our financial instruments that are measured at fair value as of April 5, 2009, consistent with the fair value hierarchy provision of SFAS No. 157:

			Total Measured at Fair Value		Quoted Market Prices In Active Markets for Identical Assets/ Liabilities (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)

Liabilities:
	Fixed-income interest rate swap agreements		$	70.6	$	—	$	70.6	$	—
		Total liabilities	$	70.6	$	—	$	70.6	$	—

        During the quarter ended April 5, 2009, we adopted FSP FAS No. 157-2, "Partial Deferral to the Effective Date of Statement 157," which deferred the application of SFAS No. 157 for certain non-financial assets and non-financial liabilities. Upon adoption, we did not have any non-financial assets or liabilities that were recognized or measured at fair value on a recurring basis, therefore there was no impact on our results of operations.

Intercompany Transactions

        We make loans to, and borrow from, our parent corporations from time to time at prevailing market interest rates. At April 5, 2009 and March 30, 2008, BMCA Holdings Corporation owed us $56.4 and $56.3 million, including interest of $1.1 and $1.0 million, respectively, and we owed BMCA Holdings Corporation $52.8 and $52.8 million, respectively, with no unpaid interest. Interest income on our loans to BMCA Holdings Corporation amounted to $0.6 and $1.0 million during the first quarter ended April 5, 2009 and March 30, 2008, respectively. Interest expense on our loans from BMCA Holdings Corporation amounted to $0.6 and $1.0 million during the first quarter ended April 5, 2009 and March 30, 2008, respectively. Loans payable to/receivable from our parent corporations are due on demand and provide each party with the right of offset of its related obligation to the other party and are subject to limitations as outlined in the Senior Secured Credit Facilities and the Senior Notes. Under the terms of the Senior Secured Revolving Credit Facility and the indenture governing our Senior Notes at April 5, 2009, we could repay demand loans to our parent corporation amounting to $52.8 million, subject to certain conditions.

        We have a management agreement, which we refer to as the Management Agreement, with ISP Management Company, Inc., a subsidiary of International Specialty Products Inc., which, together with its subsidiaries, is referred to as ISP, an affiliate, to provide us with certain management services. Based on services provided to us in 2009 under the Management Agreement, the aggregate amount payable

36

BUILDING MATERIALS CORPORATION OF AMERICA

Item 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS (Continued)

to ISP Management Company, Inc. under the Management Agreement for 2009, inclusive of the services provided to G-I Holdings, is not yet available; however, after adjusting for inflationary factors, it is currently estimated to be similar to the $7.3 million paid in 2008. We do not expect any changes to the Management Agreement to have a material impact on our results of operations.

        We and our subsidiaries purchased a substantial portion of our headlap roofing granules, colored roofing granules and algae-resistant granules, on a purchase order basis, from ISP Minerals Inc., which we refer to as ISP Minerals, an affiliate of BMCA and of ISP. The amount of mineral products purchased each year on this basis is based on current demand and is not subject to minimum purchase requirements. For the first quarter ended April 5, 2009 and March 30, 2008, we and our subsidiaries purchased $11.5 and $7.2 million, respectively, of roofing granules under this arrangement.

        In addition to the granules products we purchased, under the above purchase order basis, the balance of our granules requirements are purchased under a contract expiring in 2013. The amount of mineral products purchased each year under the contract is based on current demand and is not subject to minimum purchase requirements. Under the contract, for the first quarter ended April 5, 2009 and March 30, 2008, we purchased $18.2 and $19.1 million of roofing granules, respectively.

        In February 2009 and March 2009, after giving effect to the most restrictive of the aforementioned debt covenant restrictions, we declared and paid cash dividends of $5.0 and $5.0 million, respectively, to our parent corporation.

        Included in noncurrent assets as a tax receivable from parent corporation on our consolidated balance sheets is $0.0 and $8.4 million at April 5, 2009 and December 31, 2008, respectively, representing amounts paid in excess of amounts due to G-I Holdings with respect to 2006 under the Tax Sharing Agreement. We utilized the remaining receivable balance at December 31, 2008 during our first quarter ended April 5, 2009. These amounts are included in the net payable to related parties/parent corporations in our consolidated statements of cash flows.

Contingencies

        See Note 13 to Consolidated Financial Statements for information regarding contingencies.

Economic Outlook

        We do not believe that inflation has had a material effect on our results of operations during the first quarter of 2009. However, we cannot assure you that our business will not be affected by inflation in the future, or by increases in the cost of energy and asphalt purchases used in our manufacturing process principally due to fluctuating oil prices.

        The prices of energy and crude oil continued to decline during the first quarter of 2009, including the price of asphalt and other petroleum-based raw materials. The decline was primarily due to, in our opinion, the current worldwide economic conditions, which has resulted in weaker demand. The decline in crude oil prices in the first quarter of 2009 caused a moderate decline in asphalt and other petroleum-based raw materials. Due to the strength of our manufacturing operations, which allows us to use many types of asphalt, together with our ability to secure alternative sources of supply, we do not anticipate that any potential disruption in the supply of asphalt will have a material impact on future net sales, although no assurances can be provided in that regard. We will attempt to pass on future cost increases from suppliers as needed; however, no assurances can be provided that these price increases will be accepted in the marketplace.

Contractual Obligations

        There have been no significant changes to our contractual obligations during the first quarter ended April 5, 2009. For a further discussion on our contractual obligations related to minimum purchase obligations reference is made to Management's Discussion and Analysis of Financial Condition and Results of Operations "Contractual Obligations" in our 2008 Form 10-K.

New Accounting Pronouncements

        In December 2007, the Financial Accounting Standards Board, which we refer to as FASB, issued SFAS No. 141 (revised in 2007) "Business Combinations", which we refer to as SFAS No. 141R, which provides revised guidance on how an acquiring company should recognize and measure the identifiable assets acquired, liabilities assumed, any noncontrolling interests, and goodwill acquired in a business combination. SFAS No. 141R also expands the required disclosures related to the nature and financial statement effects of business combinations and became effective on a prospective basis for business combinations completed in fiscal years beginning after December 15, 2008. We adopted the provisions of SFAS No. 141R during our first quarter beginning January 1, 2009, and the adoption did not have any impact on our consolidated financial statements.

        In April 2009, the FASB issued FASB Staff Position, which we refer to as FSP, FAS No. 141(R)-1, "Accounting for Assets Acquired and Liabilities Assumed in a Business Combination That Arise from Contingencies", which we refer to as FSP FAS No. 141(R)-1. FSP FAS No. 141(R)-1 requires that assets acquired and liabilities assumed in a business combination that arise from contingencies be recognized at fair value if fair value can be reasonably estimated. If fair value cannot be reasonably estimated, the assets or liabilities would generally be recognized in accordance with SFAS No. 5, "Accounting for Contingencies", which we refer to as SFAS No. 5, and FASB Interpretation No. 14, "Reasonable Estimation of the Amount of a Loss". Furthermore, the FASB removed the subsequent accounting guidance for assets and liabilities arising from contingencies from SFAS No. 141(R). FSP FAS No. 141(R)-1 also eliminates the requirement to disclose an estimate of the range of possible outcomes of recognized contingencies at the acquisition date. For unrecognized contingencies, the FASB requires that entities include only the disclosure required by SFAS No. 5. We will adopt FSP FAS No. 141(R)-1 during our second quarter ending July 5, 2009, and its effect on our results of operation or financial position in future periods will depend on the nature and significance of any future business combination.

        In December 2007, the FASB issued SFAS No. 160, "Noncontrolling Interests in Consolidated Financial Statements", which we refer to as SFAS No. 160. SFAS No. 160 establishes requirements for ownership interests in subsidiaries held by parties other than us (minority interests) to be clearly identified and disclosed in the consolidated statement of financial position within equity, but separate from the parent's equity. Any changes in the parent's ownership interests are required to be accounted for in a consistent manner as equity transactions and any noncontrolling equity investments in deconsolidated subsidiaries must be measured initially at fair value. SFAS No. 160 became effective on a prospective basis for fiscal years beginning after December 15, 2008; however, the presentation and disclosure requirements must be retrospectively applied to comparative financial statements. We adopted the provisions of SFAS No. 160 in our first quarter beginning January 1, 2009, and the adoption did not have any impact on our consolidated financial statements because we do not have any noncontrolling interests.

38

BUILDING MATERIALS CORPORATION OF AMERICA

Item 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS (Continued)

        In March 2008, the FASB issued SFAS No. 161, "Disclosures about Derivative Instruments and Hedging Activities", which we refer to as SFAS No. 161. SFAS No. 161 amends SFAS No. 133 and is intended to improve financial reporting related to derivative instruments and hedging activities by requiring enhanced disclosures to enable investors to better understand their effects on an entity's financial position, financial performance, and cash flows. The provisions of SFAS No. 161 became effective on a prospective basis for fiscal years beginning on or after November 15, 2008. We adopted the disclosure provisions of SFAS No. 161 during our first quarter of fiscal year beginning January 1, 2009. Since SFAS No. 161 requires only disclosures, there was no impact on our consolidated financial statements. See Derivative and Hedging Transactions for the required disclosures.

        In April 2008, the FASB issued FSP FAS No. 142-3, "Determination of the Useful Life of Intangible Assets", which we refer to as FSP FAS No. 142-3, which amends the factors an entity should consider in developing renewal or extension assumptions used in determining the useful life of recognized intangible assets under SFAS No. 142, "Goodwill and Other Intangible Assets". This new guidance applies prospectively to intangible assets that are acquired individually or with a group of other assets in business combinations and asset acquisitions. FSP FAS No. 142-3 became effective for financial statements issued for fiscal years and interim periods beginning after December 15, 2008. We adopted the provisions of FSP FAS No. 142-3 during our first quarter beginning January 1, 2009, and the adoption did not have any impact on our consolidated financial statements.

        In May 2008, the FASB issued SFAS No. 162, "The Hierarchy of Generally Accepted Accounting Principles", which we refer to as SFAS No. 162, which identifies the sources of accounting principles and the framework for selecting principles to be used in the preparation and presentation of financial statements in accordance with United States generally accepted accounting principles. SFAS No. 162 will be effective 60 days after the SEC approves the Public Company Accounting Oversight Board's amendments to Interim Audit Standards Section 411, "The Meaning of Present Fairly in Conformity With Generally Accepted Accounting Principles". We will adopt the provisions and evaluate the impact of SFAS No. 162 upon its effective date.

        In December 2008, the FASB issued FSP FAS No. 132(R)-1, "Employers' Disclosures about Postretirement Benefit Plan Assets", which we refer to as FSP FAS No. 132(R)-1, which provides additional guidance on an employers' disclosures about plan assets of a defined benefit pension or other post retirement plan. FSP FAS No. 132(R)-1 is effective for financial statements issued for fiscal years ending after December 15, 2009. We will adopt the provisions of FSP FAS No. 132(R)-1 for our fiscal year beginning January 1, 2010, which will improve the disclosures in the financial statements related to the assets held by our defined pension and postretirement plans.

        In April 2009, the FASB issued FSP FAS No. 157-4, "Determining Fair Value When the Volume and Level of Activity for the Asset or Liability Have Significantly Decreased and Identifying Transactions That Are Not Orderly", which we refer to as FSP FAS No. 157-4. According to the guidance, if an entity determines that the level of activity for an asset or liability has significantly decreased and that a transaction is not orderly, further analysis of the transaction or quoted prices is required, and a significant adjustment to the transaction or quoted prices may be deemed necessary to estimate the fair value in accordance with SFAS No. 157, "Fair Value Measurements", which we refer to as SFAS No. 157. FSP FAS No. 157-4 is effective on a prospective basis for interim and annual periods ending after June 15, 2009 with early adoption permitted for periods ending after March 15, 2009. We will adopt the provisions of FSP FAS No. 157-4 for our second quarter ending July 5, 2009 and are currently evaluating the impact the provisions will have on our consolidated financial statements.

Item 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS (Continued)

        In April 2009, the FASB issued FSP FAS No. 107-1 and Accounting Principles Board 28-1 "Interim Disclosures about Fair Value of Financial Instruments", which we refer to as FSP FAS No. 107-1. FSP FAS No. 107-1 amends SFAS No. 107 "Disclosures about Fair Value of Financial Instruments" by requiring an entity to provide disclosures about fair value measurements of financial instruments in interim financial information. FSP FAS No. 107-1 is effective on a prospective basis for interim and annual periods ending after June 15, 2009 with early adoption permitted for periods ending after March 15, 2009. We will adopt the required disclosure provisions in our second quarter ending July 5, 2009. Since FSP FAS No. 107-1 only requires additional disclosures, there will be no impact on our consolidated financial statements.
