NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

Note 1 — General

The attached consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted. The company believes that the disclosures included herein are adequate to make the information presented not misleading. These consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes included in the company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2005. The unaudited financial information contained herein has been prepared in conformity with accounting principles generally accepted in the United States of America on a consistent basis and does reflect all adjustments (consisting of normal recurring accruals) which are, in the opinion of management, necessary for a fair presentation of the results of operations for the three-month and nine-month periods ended March 31, 2006 and 2005. Because of seasonal, weather-related conditions in some of the company’s market areas, sales can vary at times, and results of any one quarter or other interim reporting period should not necessarily be considered as indicative of results for a full fiscal year.

The company has revised its fiscal 2005 consolidated statement of cash flows to present the operating and investing portion of cash flows attributable to discontinued operations on a separately identifiable basis. The company had previously recorded these amounts on a combined basis.

Note 2 — Company Segments

The Premium Roofing Products segment manufactures premium laminated fiberglass asphalt shingles and accessory products. The segment includes RGM Products, Inc. (RGM), which was acquired in August 2005, and manufactures high-profile hip and ridge and other roofing related products. The Composite Building Products segment manufactures composite wood decking, railing, marine dock, and other OEM products. The Specialty Fabric Technologies segment is a marketing operation developed to create brand awareness and promote increased sales of Elk’s nonwoven specialty fabric products, which includes external sales of coated and uncoated nonwoven fabrics used in fire barrier technologies, various applications for other industries and in asphalt shingles. Fire barrier technologies feature fire retardant coatings designed for use in bedding, home furnishings, and other consumer products. The Surface Finishes segment includes hard chrome and other finishes designed to extend the life of steel machinery components operating in abrasive environments. Prior to fiscal 2006, fire barrier technologies and the Surface Finishes segment were combined and shown as Other, Technologies. Prior to fiscal 2006, external sales of coated and uncoated nonwoven fabrics were included in the Premium Roofing Products segment. Corporate and Other represents corporate office expenses and other expense items not allocated to the operating segments. In fiscal 2005, both Cybershield, Inc. (Cybershield) and Ortloff Engineers, LTD (Ortloff) were sold. Both companies are reported as discontinued operations in all periods presented. Financial information by company segment is summarized as follows:

Note 3 — Cash, Cash Equivalents and Short-Term Investments

Cash equivalents represent money market funds subject to daily redemption. Short-term investments consist of Auction Rate Securities (ARS) and Variable Rate Demand Notes (VRDN) and are carried at cost or par value, which approximates the fair market value. The company’s ARS and VRDN investments are tax-exempt instruments of high credit quality. The primary objectives of both types of investments are safety, preservation of invested funds and liquidity sufficient to meet cash flow requirements. Both ARS and VRDN securities have variable rates tied to short-term interest rates. Interest rates on ARS securities reset through a modified Dutch auction process at predetermined short-term intervals, either every 7, 28, or 35 days. Interest rates on VRDN securities reset weekly and can be tendered for sale upon notice (of generally no longer than seven days) to the remarketing agent in the secondary market to other investors. Although both ARS and VRDN securities are issued and rated as long-term securities, they are priced and traded as short-term instruments. The company classifies these short-term investments as available for sale in accordance with SFAS No. 115, “Accounting for Certain Instruments in Debt and Equity Securities.”

The company reflects disbursements as trade accounts payable until such time as payments are presented to the bank for payment. At March 31, 2006 and June 30, 2005, disbursements totaling approximately $18,000,000 and $23,000,000, respectively, had not been presented for payment to the bank.

Note 4 — Earnings Per Share

Basic earnings per share is computed based on the average number of common shares outstanding. Diluted earnings per share includes outstanding stock options and unvested restricted shares. In accordance with SFAS No. 128, “Earnings per Share,” diluted earnings (or loss) per share from discontinued operations presented on the Consolidated Statements of Operations were computed utilizing the same number of potential common shares used in computing the diluted per share amount for income from continuing operations, regardless of whether those amounts were anti-dilutive to their respective basic per share amounts. Performance share awards have been excluded from the calculation of diluted earnings per share, as the conditions necessary for their issuance have not been satisfied as of the end of the reporting period. The following table sets forth the computation of basic and diluted earnings per share from continuing operations:

The company has issued Senior Notes (Notes) summarized as follows (in thousands):


Principal
Amount		Maturity	Interest Rate
$	25,000	July 2007	4.69	%
$	60,000	June 2009	6.99	%
$	60,000	June 2012	7.49	%
$	50,000	November 2014	6.28	%

$	195,000

In June 2002, the company entered into an interest rate swap to effectively convert the interest rate from fixed to floating on $60,000,000 of Notes through June 2012. For this fair value hedge, both the fair value of the derivative and the underlying hedged item are reported in the balance sheet. At March 31, 2006, the fair value of the derivative was $632,000 and this amount was included in other assets and as an increase in the carrying value of long-term debt. Changes in the fair value of the derivative and the underlying hedged item offset and are recorded each period in other income or expense, as applicable. In July 2004, the company entered into a second interest rate swap to effectively convert the interest rate from fixed to floating on $25,000,000 of Notes through July 2007. This interest rate swap is also a fair value hedge with the same accounting and reporting as the aforementioned interest rate swap. At March 31, 2006, the fair value of the derivative was a liability of $458,000 and is recorded in accrued liabilities and as a decrease in the carrying value of long-term debt.

At March 31, 2006, the company had $125,000,000 of primary credit available under a Revolving Credit Facility (Facility), including up to a maximum of $10,000,000 in letters of credit through November 30, 2008. At March 31, 2006, there were no borrowings outstanding on the Facility and $3,852,000 of letters of credit were outstanding.

Both the Notes and the Facility contain financial covenants which require that the company maintain a specified minimum consolidated net worth, and a maximum debt to capitalization ratio, based on defined terms. The Facility also contains a minimum fixed charge coverage ratio and the Notes contain a minimum interest coverage ratio, also based on defined terms. Dividend payments and stock repurchases are also limited by the Facility to certain specified levels. At March 31, 2006, the company was in compliance with all of these financial covenants.

Other debt includes various mortgage debt and notes payable assumed in connection with acquisitions. The majority of these obligations, which included both fixed rate and variable rate instruments, are secured by liens on the assets acquired, and are due at various dates through June 2020.

Note 7 — Stock-Based Compensation

The Compensation Committee of the Board of Directors has established a current practice of awarding ElkCorp officers 75% of a long-term incentive compensation award in the form of performance shares (as described below) and 25% in the form of stock options. Other key employees receive their long-term incentive compensation in the form of awards of performance shares and stock loan grants. Stock-based compensation is granted to officers, directors and certain key employees in accordance with the provisions of the shareholder approved 2004 Amended and Restated ElkCorp Equity Incentive Compensation Plan (Equity Incentive Compensation Plan). This plan provides for grants of stock options, performance shares and restricted stock.

Stock Options —

The company’s Equity Incentive Compensation Plan provides for the granting of incentive and nonqualified stock options to directors, officers and key employees of the company for purchase of the company’s common stock. Stock options are generally granted for a ten-year term. Options granted to officers and key employees generally vest ratably over three-year or five-year periods. Options granted to nonemployee directors fully vest at grant date. Options granted prior to July 1, 2005 to employees who have reached retirement age are amortized over the applicable vesting period until such time that they announce their intention to retire. At that time, remaining unrecognized compensation is recorded as compensation expense during the remainder of their employment.

Prior to fiscal 2006, the company accounted for its stock options under the recognition and measurement provisions of APB Opinion No. 25 and related interpretations. Effective July 1, 2005, the company adopted the provisions of SFAS No. 123 (Revised 2004), “Share-Based Payments” (SFAS 123 (R)), and selected the modified prospective method to initially report stock-based compensation amounts in the consolidated financial statements. The company is currently using the Black-Scholes option pricing model to determine the fair value of all option grants. For option grants issued in the nine-month period ended March 31, 2006, the following weighted-average assumptions were used:


Dividend yield:		0.85	%
Risk-free interest rate:		4.15	%
Expected market price volatility:		.39
Expected life of options:	8 years
Fair value of grants:	$	13.37

For the three-month and nine-month periods ended March 31, 2006, the company recorded $1,033,000 and $3,321,000, respectively, for stock-based compensation expense related to stock option grants. This amount is recorded in selling, general and administrative expense. The company issues treasury shares, if available, to satisfy stock option exercises. If treasury shares are unavailable, new shares are issued. At March 31, 2006, there is $2,887,000 of total unrecognized compensation cost related to unvested stock options remaining to be recognized. Of this total, $1,013,000 will be recognized in the last three-months of fiscal 2006 and $1,874,000 will be recognized in subsequent years through fiscal 2008. Beginning July 1, 2005, any tax deductions in excess of recognized compensation costs are reported as financing cash flows rather than operating cash flows as was prescribed prior to the adoption of SFAS 123(R). For the nine-month period ended March 31, 2006, $720,000 of excess tax benefits relating to stock option exercises were recorded. There were no excess tax benefits from the exercise of options in the nine-month period ended March 31, 2005.

In December 2004 and July 2005, the company entered into Performance Stock Award agreements (PSA Agreements) granting performance stock awards (PSAs) to certain of the company’s officers and other key employees under the Equity Incentive Compensation Plan. The PSAs consist of a contingent right to receive whole shares of the company’s common stock if the company meets specified performance criteria over a three-year performance period. The performance criteria for 70% of the total PSA is based on the company’s return on equity (ROE) measured against all New York Stock Exchange (NYSE) listed companies, and 30% of the total PSA is based on the company’s total shareholder return (TSR), or stock appreciation plus dividends, measured against all NYSE listed companies.

The company currently estimates that the probable number of shares to be issued at the end of the three-year performance period ending June 30, 2007, will be 136,870 shares. The maximum potential number of shares that can be issued for this performance period is 205,305 shares. For the three-year performance period ending June 30, 2008, the company estimates that the probable number of shares to be issued will be 122,170 shares. The maximum potential number of shares that can be issued for this second performance period is 183,255 shares. Prior to July 1, 2005, the initial award was accounted for using variable accounting as prescribed by APB No. 25, “Accounting for Stock Issued to Employees”, and related interpretations, and the disclosure-only provisions of SFAS No. 123, “Accounting for Stock-Based Compensation”. Under APB 25, performance shares were accounted for by charging a ratable portion of compensation expense during each accounting period based on the probable number of shares to be issued times the price of ElkCorp common stock at the end of each period. Beginning July 1, 2005, all performance shares are accounted for at fair value in accordance with the provisions of SFAS No. 123(R) multiplied by the probable number of shares to be issued. During the three-month and nine-month periods ended March 31, 2006, $573,000 and $1,625,000, respectively, was charged to compensation expense for performance shares, based on the probable number of shares that will be issued at the end of the applicable performance periods. During the three-month and nine-month periods ended March 31, 2005, $545,000 and $1,353,000 respectively, was charged to compensation expense for performance shares. At March 31, 2006, there is $3,592,000 of total unrecognized compensation cost related to performance stock awards remaining to be recognized based on the currently estimated probable number of shares to be issued. Of this total, $573,000 will be recognized in the last three months of fiscal 2006 and $3,019,000 will be recognized in subsequent years through fiscal 2008. Compensation expense attributable to performance stock awards is classified as selling, general and administrative expense.

Restricted Stock —

The Equity Incentive Compensation Plan also provides for grants of restricted stock to directors and employees of the company. Grantees generally have all rights of a shareholder except that unvested shares are held in escrow. Restricted shares either vest 33 1/3% per year over a three-year restriction period or 20% per year over a five-year restriction period. In the nine-month period ended March 31, 2006, 32,590 restricted shares were granted at market prices ranging from $30.18 to $35.55 per share. At grant date, the value of restricted stock is reflected as unearned compensation in shareholders’ equity and is amortized over the applicable restriction period. Restricted stock issued to directors vest in full three years after grant date. In the three-month and nine-month periods ended March 31, 2006, compensation expense of $411,000 and $1,111,000, respectively, was recognized relating to restricted stock awards. In the three-month and nine-month periods ended March 31, 2005, compensation expense of $328,000 and $919,000, respectively, was recognized relating to restricted stock awards. At March 31, 2006, there is $3,384,000 of total unrecognized compensation cost related to unvested restricted stock remaining to be recognized. Of this total $450,000 will be recognized in the last three-months of fiscal 2006 and $2,934,000 will be recognized in subsequent years through fiscal 2011. Compensation expense attributable to restricted shares is classified as selling, general and administrative expense.

Stock/Loan Plan —

Under the company’s Stock/Loan Plan, certain employees are granted loans based on a percentage of their salaries, the performance of their operating units, and also as long-term incentive compensation awards, for the purpose of purchasing the company’s common stock. Under the Stock/Loan Plan, a ratable portion of the loans, which are unsecured, and any accrued interest are forgiven and recognized as compensation expense over five years of continuing service with the company. If employment is terminated for any reason except death, disability or retirement, the balance of the loan becomes due and payable. Loans outstanding at March 31, 2006, and June 30, 2005, totaling $4,338,000 and $2,963,000, respectively, are included in other assets. In compliance with certain provisions of the Sarbanes-Oxley Act of 2002, no loans have been granted to executive officers of ElkCorp since the passage of the Sarbanes-Oxley Act of 2002.

Note 8 — Product Warranties

The company provides its customers with limited warranties on certain products. Limited warranties relating to products sold by the Premium Roofing Products segment generally range from 30 to 50 years and the warranties relating to Composite Building Products are generally for 20 years. Warranties relating to Specialty Fabric Technologies and Surface Finishes are not significant to their operations. Warranty reserves are established based on known or probable claims, together with historical experience factors. The company periodically assesses the adequacy of its recorded warranty liability and adjusts the amount as necessary. Changes in the company’s warranty liability during the current year period were as follows:


(In thousands)	Warranty Liability

Note 9 — Environmental Risk

ElkCorp and its subsidiaries are subject to federal, state and local requirements regulating the discharge of materials into the environment, the handling and disposal of solid and hazardous wastes, and protection of the public health and the environment generally (collectively, Environmental Laws). Certain facilities of our subsidiaries ship waste products to various waste management facilities for treatment or disposal. Governmental authorities have the power to require compliance with these Environmental Laws, and violators may be subject to civil or criminal penalties, injunctions or both. Third parties may also have the right to sue for damages and/or to enforce compliance and to require remediation of contamination. If there are releases or if these facilities do not operate in accordance with Environmental Laws, or their owners or operators become financially unstable or insolvent, our subsidiaries are subject to potential liability.

- 10 -

The company and its subsidiaries are also subject to Environmental Laws that impose liability for the costs of cleaning up contamination resulting from past spills, disposal, and other releases of hazardous substances. In particular, an entity may be subject to liability under the Federal Comprehensive Environmental Response, Compensation and Liability Act (CERCLA or Superfund) and similar state laws that impose liability — without a showing of fault, negligence, or regulatory violations — for the generation, transportation or disposal of hazardous substances that have caused, or may cause, environmental contamination. In addition, an entity could be liable for cleanup of property it owns or operates even if it did not contribute to the contamination of such property. From time to time, the company and its subsidiaries may incur such remediation and related costs at company-owned plants and certain offsite locations maintained by other parties.

Chromium Corporation (Chromium), one of the company’s subsidiaries, has engaged in limited remediation activities at the site of its former plating operation in Lufkin, Texas. Soil sampling results from a pre-closing environmental evaluation of the site indicated the necessity of localized cleanup. Chromium has entered the property into the Texas Voluntary Cleanup Program (VCP). Under this program, the Texas Commission on Environmental Quality (TCEQ) reviews the voluntary clean-up plan the applicant submits, and, when the work is complete, issues a certificate of completion, evidencing cleanup to levels protective of human health and the environment and releasing prospective purchasers and lenders from liability to the state. Properties entered into the VCP are protected from TCEQ enforcement actions.

In fiscal 2004, Chromium completed a supplemental groundwater and soil assessment at the Lufkin facility. The assessment further defined the horizontal and vertical extent of metals in soils, assessed the horizontal extent of metals in groundwater, and estimated the direction of groundwater movement. Chromium submitted its Affected Property Assessment Report (APAR) to the TCEQ. In June 2004, the TCEQ issued a letter accepting Chromium’s APAR in substantially all respects, indicating that no further assessment of the extent of contamination was necessary. Chromium has received approval from the TCEQ for a Remediation Action Plan (RAP) that describes remediation activities and engineering controls to clean up the site under the VCP to a site specific risk-based clean-up standard as prescribed by the Texas Risk Reduction Program. The company believes that current findings indicate that remediation activities will be similar to a plan utilized at another Chromium plant. This assessment, in conjunction with projections developed in finalizing the RAP that are site specific, resulted in the company recording an accrued liability of $700,000 in fiscal 2005. Certain other scenarios, none of which are reasonably expected at this time, could potentially result in material costs to the company.

The company’s operations are subject to extensive Environmental Laws. Other than the possible costs associated with the previously described Chromium matter, management does not believe the company will be required to expend amounts which will have a material adverse effect on the company’s consolidated results of operations, financial position or liquidity. The company establishes and maintains reserves for such known or probable remediation activities in accordance with SFAS No. 5 and AICPA Statement of Position 96-1. Such environmental laws are frequently changed and could result in significantly increased cost of compliance. The company anticipates that its subsidiaries will incur costs to comply with Environmental Laws, including remediating any existing non-compliance with such laws and achieving compliance with anticipated future standards for air emissions and reduction of waste streams. Such subsidiaries expend funds to minimize the discharge of materials into the environment and to comply with governmental regulations relating to the protection of the environment. Further, certain of our manufacturing operations utilize hazardous materials in their production processes. As a result, the company and its subsidiaries incur costs for recycling or disposal of such materials and may incur costs for remediation activities at company facilities and off-site from time to time.

Note 10 — Acquisitions

On August 25, 2005, Elk Premium Building Products, Inc., acquired the outstanding shares of RGM Products, Inc. (RGM), a privately-held manufacturer of high-profile hip and ridge and other roofing related products and certain other assets related to RGM’s business. The acquisition enhances ElkCorp’s current roofing accessory business and allows the company to offer the broadest ridge product line in its industry. The purchase price of the acquisition was $24,285,000, together with the assumption of certain related indebtedness and costs of acquisition.

The allocation of the purchase price to assets acquired and liabilities assumed is preliminary and is subject to further analysis. Any modification of purchase price will result in an increase or decrease in the allocation to goodwill. On a preliminary basis, the purchase price was allocated to $27,759,000 for net tangible assets, $10,700,000 of identifiable intangible assets and $11,040,000 of goodwill, taking into account indebtedness and current liabilities assumed. The results of RGM’s operations are included in the results of operations prospectively from the date of

Note 12 — Discontinued Operations

In December 2003, the company concluded that the risk and prospects for future success of Cybershield did not justify the additional investment of capital and other resources required to continue Cybershield’s operations. Accordingly, the decision was made to discontinue Cybershield and to sell its operations or its assets. On August 10, 2004, the company sold substantially all assets of Cybershield, excluding its Canton, Georgia facility, to the Cybershield management group for $1,293,000 in cash. The sale price approximated the book value of assets, net of assumed liabilities, at the date of sale. In the first quarter of fiscal 2005, the company recorded a pretax impairment charge of $651,000 on remaining Canton assets. In the third quarter of fiscal 2005, the Canton land, building and certain equipment was sold at a price that approximated book value.

Ortloff Engineers, LTD (Ortloff) was engaged in licensing proprietary technologies and providing related engineering services to the natural gas processing industries, with particular emphasis on the natural gas liquids recovery, sulfur recovery and liquefied natural gas segments. Although Ortloff had a long history of success and profitability, in fiscal 2005 the company concluded that it did not fit into its focus on building products platforms and it was positioned for sale. In the fourth quarter of fiscal 2005, Ortloff was sold to a financial buyer for cash. The company will not participate in Ortloff’s management or ongoing operation in any manner, although ElkCorp retained $4,400,000 in long-term license receivables, which the purchaser will collect on the company’s behalf for a service fee. In addition, ElkCorp retained a portion of contingent license fees on certain projects that were in process at the date of sale. The maximum future benefit of contingent license fees is approximately $2,100,000, although there is no assurance that any of these contingent fees will ultimately be realized.

Note 13 — Income Taxes

The American Jobs Creation Act of 2004 (the Act) provides tax relief to U.S. domestic manufacturers. The Financial Accounting Standards Board (FASB) directed its staff to issue Financial Staff Position (FSP) FAS 109-1, “Application of FASB Statement No. 109, Accounting for Income Taxes, to the Tax Deduction on Qualified Production Activities Provided by the American Jobs Creation Act of 2004.” FSP FAS 109-1 states that a manufacturers’ deduction provided for under the act should be accounted for as a special deduction and not as a tax rate reduction. The effective tax rate of 37.1% includes the estimated tax deduction for this item for fiscal 2006.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Executive Overview

This discussion should be read in conjunction with the Consolidated Financial Statements and Notes to Consolidated Financial Statements included elsewhere herein and our Annual Report on Form 10-K for the year ended June 30, 2005. ElkCorp has achieved company records for shipments of laminated shingles and has been able to sustain its successful operating performance in the first nine months of fiscal 2006. Following an outstanding year in fiscal 2005, the demand for our laminated shingles has continued at record levels this fiscal year to date. However, due to escalating transportation, energy, raw material costs (especially asphalt costs) and changes in regional mix for product shipments, our margins have been decreasing as we have been able to pass along only a portion of higher costs through higher net selling prices. Overall gross margin, as a percentage of sales, was also reduced by slower than anticipated shipments into the relatively higher margin Florida market due, in part, to longer lead times for insurance claim settlements following Hurricane Wilma, which occurred in the early part of fiscal 2006. Product expected to be shipped into Florida was shipped to the Gulf Coast storm areas that were affected by Hurricanes Rita and Katrina during the calendar 2005 hurricane season. We have been able to achieve a 13% year-to-year increase in production at our roofing plants as of March 31, 2006 and incoming order levels have been strong in most regions of the United States. Compared to the first nine months of the prior fiscal year, shingle shipments in the first nine months of fiscal 2006 increased approximately 10% and average selling prices increased 5.9%.

On August 25, 2005, we acquired RGM Products, Inc. (RGM), a privately-held manufacturer of high-profile hip and ridge and other roofing related products based in Fresno, California, for $24,285,000 in cash and the assumption of certain related indebtedness and costs of acquisition. This acquisition enhances our current roofing accessories business and allows us to offer the broadest ridge product line in the industry. The RGM acquisition has been accretive to results since the date of acquisition.

Our Composite Building Products platform reported an operating loss in both the three-month and nine-month periods ended March 31, 2006. Although operating results have been disappointing, decking sales continue to increase on a year-over-year basis. We remain committed to the ultimate success of this platform. We believe we have the cost structure, yields, products and market acceptance to reach profitability in this business.

Beginning in fiscal 2006, we are reporting results for Specialty Fabric Technologies, a marketing division developed to create brand awareness and promote increased sales of our nonwoven specialty fabrics products and VersaShield fire barrier technology, as a separate segment. Our Surface Finishes business does not fit into our focus on building products platforms and continues to be offered for sale. We currently plan for this business to remain as one of our business platforms if it is not sold.

Performance Data

The following table and subsequent discussion set forth performance data from our continuing operations, expressed as a percentage of net sales for the periods indicated. This data and the accompanying discussion and analysis should be read in conjunction with the Consolidated Financial Statements and Notes to Consolidated Financial Statements included elsewhere herein.

Changes in the Three-Month Period Ended March 31, 2006 Compared to the Three-Month Period Ended March 31, 2005

Overall Performance

Sales from continuing operations of $243,194,000 during the three-month period ended March 31, 2006 were 20.5% higher than $201,871,000 in the same period in the prior fiscal year. Sales of premium roofing shingles and accessory products increased during the current year period as a result of continuing strong demand in most regions of the United States of America, particularly in those regions affected by Hurricanes Katrina and Rita which occurred in the early part of fiscal 2006. Sales in the current year were also bolstered by the acquisition of RGM and incremental sales from the Composite Building Products and Specialty Fabric Technologies segments. During the three-month period ended March 31, 2006, operating income from continuing operations of $18,801,000 was 24.6% lower than $24,928,000 for the same period last year. The reduction in operating income is primarily a result of higher transportation, energy, and raw material costs.

The percentage of cost of sales to sales increased to 82.6% in the three-month period ended March 31, 2006 compared to 78.2% for the same period last year. Escalating raw material, energy and transportation costs continue to pressure margins for our roofing plant operations. During the three-month period ended March 31, 2006, asphalt prices were approximately 35% higher than in the same quarter in fiscal 2005. As anticipated, there has been margin erosion in the quarter ended March 31, 2006, as we have been able to offset only a portion of higher costs for these items with price increases. Selling, general and administrative (SG&A) costs in the third quarter of fiscal 2006 were 23.5% higher than in the same period last year. As a percentage of sales, SG&A costs increased to 9.7% of net sales in the three-month period ended March 31, 2006, compared to 9.4% in the same three-month period in fiscal 2005. Much of the increase in year-to-year SG&A costs relates to newly acquired RGM being included in consolidated financial results and the ramp-up of operations for Composite Building Products. In addition, a significant component of the increased SG&A costs was stock-based compensation, as we implemented the provisions of SFAS No. 123(R) effective July 1, 2005. Total stock-based compensation in the third quarter of fiscal 2006 was $2,017,000 compared to $873,000 for the same quarter last year.

Interest expense and other, net, was $2,700,000 in the third quarter of fiscal 2006 compared to $2,614,000 in the same prior year period. In the period ended March 31, 2006, no interest was capitalized, compared to $272,000 in the third quarter of fiscal 2005. Rising interest rates on variable rate debt resulted in higher interest expense of approximately $300,000. However, increasing interest expense was partially offset by higher interest income from short-term investments. Our effective tax rate from continuing operations was 37.0% in the third quarter of fiscal 2006 and is expected to approximate 37.1% for fiscal 2006. The effective tax rate was 36.7% for the same quarter in fiscal 2005. The lower effective rate in fiscal 2005 was primarily attributable to more state investment tax credits being available to offset tax liabilities.

In fiscal 2005, we sold both Cybershield and Ortloff. The results for these two companies are presented as discontinued operations for each period presented.

Results of Business Segments

Sales in the Premium Roofing Products segment increased 18.6% to $220,114,000 for the three months ended March 31, 2006 compared to $185,549,000 in the same prior year period. Sales of RGM products accounted for almost half of the year-to-year increase. In the current year period, shingle unit volume continued to be strong, increasing 7.8% year-to-year, as demand remained robust in those regions of the United States affected by Hurricanes Katrina and Rita, which occurred in the early part of fiscal 2006. Damage to roofs from extreme weather such as hurricanes, hail and certain other weather events can result in higher demand for periods up to eighteen to twenty-four months depending on the extent of roof damage. Average shingle pricing in the current year quarter increased 6.5% compared to the year-ago period as a result of price increases necessary to offset rapidly escalating asphalt, energy and transportation costs. The price increases in the past year have been consistent with industry trends.

Sales of Composite Building Products were $7,545,000 in the third quarter of fiscal 2006, compared to $4,726,000 in the third quarter of fiscal 2005. In December 2005, to assist our customers’ ability to begin building inventory for the upcoming decking season, we initiated shipments of composite building products with extended payment terms. However, we believe our customers have been somewhat reluctant to place initial seasonal orders due to slower growth in the 2005 decking season which caused a general industry overstocking last year. Based on industry data, we anticipate the decking market will return to a more normalized growth rate later in the season. We are optimistic

- 15 -

about achieving continuing improvement in sales in the summer months of calendar 2006. Payments for products shipped during the winter and early spring months will generally be due during the early summer months.

In the third quarter of fiscal 2006, Specialty Fabric Technologies sales increased 44.2% to $13,616,000 from $9,443,000 in the same quarter last year. External sales of nonwoven fabrics increased primarily as a result of higher volume and pricing for roofing related fabric sales. In addition, sales of non-roofing fabrics increased approximately 58% over the third quarter of fiscal 2005. Sales of fire barrier products continue to increase but remain very small in relation to consolidated sales. Sales in the Surface Finishes segment decreased in the third quarter of fiscal 2006 to $1,919,000 compared to $2,153,000 for the same quarter last year.

Operating income for the Premium Roofing Products segment of $24,990,000 for the three-month period ended March 31, 2006 decreased 23.5% from $32,671,000 achieved in the third quarter of fiscal 2005. Despite strong demand and increased product shipments, transportation, energy and raw material costs in the quarter ended March 31, 2006 escalated at a rate in excess of our ability to achieve price increases to offset rising costs. Year-to-year margin comparisons were also negatively affected by lower shipment volume into Florida storm areas in the current year quarter, as Florida is a relatively higher margin market. Newly acquired RGM contributed $451,000 to operating income for the quarter ended March 31, 2006.

We incurred an operating loss of $2,059,000 for the Composite Building Products segment during the third quarter of fiscal 2006 compared to a $2,441,000 operating loss in the same period in the prior year. Sales were significantly higher in the quarter ended March 31, 2006 compared to the same quarter in the prior fiscal year. However, improvements in volume and contribution margin were partially offset by increased costs (including depreciation and property taxes) of the new plant which had not fully ramped up until the fourth quarter of fiscal 2005.

The Specialty Fabric Technologies marketing segment reported a $1,383,000 operating profit in the third quarter of fiscal 2006 compared to a $177,000 operating profit in the three-month period ended March 31, 2005, primarily as a result of increased sales volume, more favorable pricing and improved sales mix of higher margin products such as carpet tile, facer and air filtration.

The Surface Finishes segment had an operating profit of $212,000 in the third quarter this year compared to a $371,000 operating loss in the same quarter last year. Operating results in the quarter ended March 31, 2005, included a $300,000 charge for environmental costs at a closed facility.

Changes in the Nine-Month Period Ended March 31, 2006 Compared to the Nine-Month Period Ended March 31, 2005

Overall Performance

Sales from continuing operations of $688,000,000 during the nine-month period ended March 31, 2006 were 23.1% higher than $558,982,000 in the same period in the prior fiscal year. Sales of premium roofing shingles and accessory products increased substantially during the current year period as a result of continuing strong demand, particularly in those regions of the United States affected by hurricane damage in fiscal 2005 and the early part of fiscal 2006. During the nine-month period ended March 31, 2006, operating income from continuing operations of $59,039,000 was 8.7% lower than $64,659,000 for the same period last year.

The percentage of cost of sales to sales increased to 82.0% in the nine-month period ended March 31, 2006 compared to 79.5% for the same period last year. Escalating raw material, energy and transportation costs have continued to pressure margins all year for our roofing plant operations. To date, we have been able to partially offset higher costs for these items with price increases. However, raw material and transportation costs tend to be volatile and difficult to predict. As a result, there can be short-term margin erosion from time-to-time when the impact of price increases lags rising costs. This dynamic occurred during the second and third quarters of fiscal 2006 when costs of raw materials and transportation increased faster than our ability to achieve price increases. Selling, general and administrative (SG&A) costs in the first nine months of fiscal 2006 were 30% higher than in the same period last year. As a percentage of net sales, SG&A costs were 9.5% in the current year period compared to 9.0% in the same period in the prior fiscal year. Increased selling cost, particularly in those areas affected by high demand created by hurricane damage, together with the addition of RGM and increased sales activity for Composite Building Products, are the primary factors in higher SG&A costs. Another significant component of the increased SG&A costs was stock-based compensation, as we implemented the provisions of SFAS No. 123(R) effective July 1, 2005. Total stock-based compensation in the first nine months of fiscal 2006 was $6,057,000 compared to $2,272,000 for the first nine months of fiscal 2005.

Interest expense and other, net, was $8,525,000 in the first nine months of fiscal 2006 compared to $7,090,000 in the same prior year period. In the period ended March 31, 2006, no interest was capitalized, compared to $668,000 in the first nine months of fiscal 2005. Higher borrowings and increased interest rates on variable rate debt accounted for the majority of the year-to-year increase.

Our effective tax rate from continuing operations was 37.1% in the first nine months of fiscal 2006 and is expected to approximate this rate for fiscal 2006. The effective tax rate was 37.5% for the same period in fiscal 2005. In fiscal 2006, we are able to benefit from the manufacturers’ deduction allowed by the American Jobs Creation Act of 2004.

In fiscal 2005, we sold both Cybershield and Ortloff. The results for these two companies are presented as discontinued operations for each period presented. Discontinued operations for the first nine months of fiscal 2005 included a $651,000 impairment of Cybershield’s Canton facility, which was sold in the third quarter of fiscal 2005.

Results of Business Segments

Sales in the Premium Roofing Products segment increased 21.0% to $620,473,000 for the nine months ended March 31, 2006 compared to $512,965,000 in the same prior year period. Current year results include sales from RGM products subsequent to its acquisition. RGM sales accounted for slightly more than one-third of increased sales in the current year period. In the first nine months of fiscal 2006, shingle unit volume continued to be very strong, increasing 10% year-to-year, as demand remained strong in many regions of the United States, particularly those affected by hurricane activity in fiscal 2005 and the early part of fiscal 2006. Average shingle pricing increased approximately 5.9% compared to the year-ago period as a result of price increases implemented to offset rapidly escalating asphalt, energy and transportation costs.

Sales of Composite Building Products were $21,303,000 in the first nine months of fiscal 2006, compared to $10,968,000 in the first nine months of fiscal 2005. Pricing and volume both improved year-to-year, and the number of distributors continues to increase. We are committed to developing this business platform to take advantage of the opportunities created by increased awareness of the benefits of composite lumber compared to wood.

In the first nine months of fiscal 2006, Specialty Fabric Technologies sales increased 40.6% to $39,696,000 from $28,237,000 in the same period last year. External sales of nonwoven fabrics increased primarily as result of higher demand and improved pricing from outside roofing, facer and filtration customers. Sales of fire barrier products continue to increase but remain very small in relation to our consolidated sales total. Surface Finishes sales decreased slightly in the first nine months of fiscal 2006 to $6,528,000, compared to $6,812,000 for the same period last year.

Operating income for the Premium Roofing Products segment of $78,709,000 for the nine-month period ended March 31, 2006 decreased 4.6% from $82,484,000 achieved in the first nine months of fiscal 2005. We were able to achieve higher shingle sales volume as a result of continuing strong demand, together with better efficiency as we continue to increase production at our newest roofing plant in Tuscaloosa, Alabama. This plant was placed in service at the beginning of fiscal 2005. RGM, which was acquired August 25, 2005, added to this segment’s profitability in the period that it was included in our consolidated financial results. The silo failure in the granule storage system at our Myerstown, Pennsylvania facility encountered in the fourth quarter of fiscal 2005 did not significantly impact operating results in the first nine months of fiscal 2006. This plant operated at full capacity despite its damaged granule storage system. Initial repairs designed to correct the damaged areas at this roofing plant were completed during the quarter ended December 31, 2005. Various engineering refinements to eliminate machine productivity issues encountered in the fourth quarter of fiscal 2005 at the Tuscaloosa, Alabama roofing plant were completed early in fiscal 2006 and productivity improvements have resumed.

We incurred an operating loss of $7,577,000 for the Composite Building Products segment during the first nine months of fiscal 2006 compared to a $6,341,000 operating loss in the same period in the prior year. Higher volume and pricing, together with cost improvement from the reduction in additives used in the manufacturing process, were partially offset by increased costs from the ramp up of the new facility and additional sales personnel. We also made adjustments for returned material and non-decking inventories for this developing business in the first quarter of the current fiscal year. The operating loss reported in the nine-month period ended March 31, 2006, included an approximate $2,600,000 write-down of inventory and returned material taken in the quarter ended September 30, 2005. There have been no significant returned material or inventory valuation adjustments subsequent to the first quarter of fiscal 2006.

The Specialty Fabric Technologies marketing segment reported a $4,266,000 operating profit in the first nine months of fiscal 2006 compared to a $1,523,000 operating profit in the nine-month period ended March 31, 2005. Higher sales volumes, improved pricing and changes in product mix due to increased demand for our new non-roofing products all contributed to improved profitability.

The Surface Finishes segment had an operating profit of $656,000 in the first nine months of fiscal 2006 compared to a $228,000 operating loss in the same period last year. Fiscal 2005 results included a $700,000 charge for estimated environmental costs at its former Lufkin, Texas plating operation.

Financial Condition

Overview

Our liquidity needs generally arise principally from working capital requirements, capital expenditures, payment of dividends and interest payments. During the first nine months of fiscal 2006, we relied on internally generated funds to finance our cash requirements. Our working capital requirements typically fluctuate significantly during the year because of seasonality in some market areas. Generally, working capital requirements are higher in the spring and summer months and lower in the fall and winter months. During the three-month period ended March 31, 2006, we sold or redeemed approximately $24,000,000 of short-term investments, net, to partially fund higher seasonal working capital requirements and other cash requirements. At March 31, 2006, after these seasonal sales and redemptions of short-term investments, we had $44,501,000 in cash, cash equivalents and short-term investments available to fund growth opportunities, capital expenditures and other cash requirements. We did not borrow under our revolving credit facility during the first nine months of fiscal 2006.

Operating Activities

We generate cash flows from operating activities primarily from income from operations, after consideration of deferred taxes, stock-based compensation, depreciation and amortization. Cash flows from operating activities also either increase or decrease as a result of changes in working capital requirements. In the nine months ended March 31, 2006, we generated cash of $13,793,000 from operating activities, compared to $29,138,000 in the same nine-month period last year.

After considering $5,708,000 of trade receivables acquired in the RGM acquisition in August 2005, trade receivables at March 31, 2006 were $15,409,000 higher than at June 30, 2005 due primarily to the increased sales and the granting of extended term receivables to certain customers. In accordance with normal industry practices, extended payment terms are granted to certain customers for roofing products and composite building products shipped during the late winter and early spring months, with payments generally due during the spring and early summer. During the nine-month period ended March 31, 2006, we collected all extended term receivables, totaling $2,810,000, outstanding at June 30, 2005. At March 31, 2006, after considering $6,909,000 of inventories acquired in the RGM acquisition, inventories were $17,745,000 higher than at June 30, 2005, primarily due to higher inventory levels at our Myerstown and Tuscaloosa roofing plants at March 31, 2006 compared to June 30, 2005. Inventory levels at the end of fiscal 2005 were unusually low as a result of storm-related demand in areas of the United States of America served by those plants. Accounts payable and accrued liability balances, after consideration of those assumed in the acquisition of RGM, were lower at March 31, 2006 than at June 30, 2005, primarily as a result of the timing of the payment of trade payables. The current ratio was 3.5 to 1 at both March 31, 2006 and June 30, 2005.

Investing Activities

Cash flows from investing activities primarily reflect our capital expenditure strategy, together with activity relating to acquisitions and short-term investments. Net cash used for investing activities was $11,102,000 in the first nine months of fiscal 2006 compared to $58,515,000 in the same period in fiscal 2005. Capital expenditures in the nine-month period ended March 31, 2006 are representative of normal levels of capital expenditures, as major capacity initiatives undertaken over the past several years have been substantially completed. Other than major capacity initiatives, capital expenditures are expected to be approximately $20,000,000 per year. On August 25, 2005, we utilized $24,285,000 of available liquidity (primarily the sale of short-term investments) to finance the acquisition of RGM. During the first nine months of fiscal 2006, we had a net reduction of $30,560,000 of short-term investments to supplement cash flows from operating activities.

- 18 -

Financing Activities

Cash flows from financing activities generally reflect changes in our borrowings, together with dividends paid on common stock and exercises of stock options. Net cash used for financing activities was $6,051,000 in the first nine months of fiscal 2006, compared to $40,761,000 of cash provided in the same period last year (which included proceeds from the sale of $50,000,000 of Senior Notes).

At March 31, 2006, liquidity consisted of $44,501,000 of cash, cash equivalents, short-term investments and $121,148,000 of available borrowings under the $125,000,000 committed line of credit facility. The debt to capital ratio (after deducting cash, cash equivalents and short-term investments of $44,501,000 from $201,044,000 of principal debt) was 33.7%.

Our Board of Directors has authorized the repurchase of common stock from time to time on the open market. In the quarter ended March 31, 2006, we used approximately $4,000,000 to purchase 113,690 shares at an average price of $35.18 under this authority. As of March 31, 2006, we have repurchase authority of approximately $6,600,000 remaining.

Natural Gas Hedge Commitment

In March 2006, we entered into a hedge transaction to fix the price on a portion of our natural gas usage through September 2006. The contact value of the hedge transaction at March 31, 2006 was $1,278,000.

Off-Balance Sheet Arrangements

We have no off-balance sheet arrangements or transactions with unconsolidated, special purpose entities.

Critical Accounting Policies

Our condensed consolidated financial statements were prepared in conformity with accounting principles generally accepted in the United States of America. As such, we are required to make certain estimates, judgments and assumptions we believe are reasonable based on the information available. The accounting policies which we believe are the most critical to fully understanding and evaluating our reported financial results are:

	-		Collectibility of Accounts Receivable

	-		Accruals for Loss Contingencies, including Warranties

	-		Inventories

	-		Revenue Recognition

	-		Impairment of Long-Lived Assets

	-		Stock-Based Compensation

These critical accounting policies are described in Management’s Discussion and Analysis of Financial Condition and Results of Operations in our Form 10-K for the fiscal year ended June 30, 2005. There were no significant changes in critical accounting policies during the nine-month period ended March 31, 2006.

Business Risks and Forward-Looking Statements

In an effort to give investors a well-rounded view of our current condition and future opportunities, Management’s Discussion and Analysis of Financial Condition and Results of Operations and other sections of this Form 10-Q contain “forward-looking statements” that involve risks and uncertainties about our prospects for the future. The statements that are not historical facts are forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. These statements usually are accompanied by words such as “optimistic,” “vision,” “outlook,” “believe,” “estimate,” “potential,” “forecast,” “goal,” “project,” “expect,” “anticipate,” “plan,” “predict,” “could,” “should,” “may,” “likely,” or similar words that convey the uncertainty of future events or outcomes. These statements are based on judgments we believe are reasonable; however, ElkCorp’s actual results could differ materially from those discussed in such forward-looking statements. Factors that could cause or contribute to such differences could include, but are not limited to the following items. We undertake no obligation to update or revise publicly any forward-looking statements whether as a result of new information or future events.

Competitive Conditions

- 19 -

Our building products businesses can be affected by weather, the availability of customer and/or end-user financing, insurance claims-paying practices, and general economic conditions. In addition, our building products manufacturing businesses are highly competitive. Actions of competitors, including changes in pricing, or slowing demand for asphalt roofing products due to general or industry economic conditions or the frequency and intensity of inclement weather could result in decreased demand for our products, lower prices received or reduced utilization of plant facilities. Further, changes in building and insurance codes and other standards from time to time can cause changes in demand, challenges in meeting refined product specifications, or increases in costs that may not be passed through to customers.

Higher Raw Material, Energy and Transportation Costs

In our building products businesses, the significant raw materials are ceramic-coated granules, asphalt, glass fibers, resins, mineral filler, polypropylene, wood particles and various additives for product preservation. Increased costs of raw materials can result in reduced margins, as can higher energy, trucking and rail costs. Further, our largest long-term contracts for asphalt and certain other raw materials expired at the end of calendar year 2005 and in early calendar year 2006. Negotiations of several new contracts are in process, but there is no assurance that new contracts will be agreed upon. As we initiate new multisourcing strategies, certain raw materials are currently being purchased on a purchase order basis. Either alternative (new contracts or purchases using purchase orders) may result in higher or lower raw material costs. Historically, we have been able to pass some of the higher raw material, energy and transportation costs through to the customer. Should we be unable to recover higher raw material, energy and/or transportation costs, including higher trucking costs resulting from fuel surcharges and regulatory changes in the trucking industry, through price increases of our products, operating results could be adversely affected and/or lower than projected.

Temporary Shortages or Disruptions

Temporary shortages or disruptions in the supply of raw materials or the availability of transportation do result from time to time from a variety of causes. In addition, supplies of asphalt can be affected by refiners’ decisions to process alternative products from the residuals in the refining of crude oil. If we experience temporary shortages or disruptions in the supply of raw materials or the availability of transportation, operating results could be lower than projected.

Productivity of New Facilities

We have been involved in a significant expansion plan over the past several years, including the construction of new facilities and the expansion of existing facilities. Progress in achieving anticipated operating efficiencies and financial results is difficult to predict for new and expanded plant facilities. If such progress is slower than anticipated, or if demand for products produced at new or expanded plants does not meet current expectations, operating results could be lower than projected.

Utilization of Hazardous Materials

Certain facilities of our subsidiaries must utilize hazardous materials in their production process. As a result, we could incur costs for remediation activities at our facilities or off-site and other related exposures from time to time in excess of established reserves for such activities.

Litigation and Claims

We are involved in various legal proceedings and claims, including claims arising in the ordinary course of business. Our litigation and claims are subject to inherent and case-specific uncertainty. The outcome of such litigation and claims depends on numerous interrelated factors, many of which cannot be predicted.

Higher Interest Rates

We currently anticipate that most of our needs for new capital in the near future will be met with current amounts of cash, cash equivalents and short-term investments, internally generated funds and borrowings under our available credit facilities. Significant increases in interest rates could substantially affect our borrowing costs or our cost of alternative sources of capital.

Loss of Key Customers

- 20 -

The majority of our sales relate to our building products platforms, and our primary customers are building products distributors. The ten largest customers account for approximately 50% of annual consolidated sales and one customer accounts for approximately 19% of consolidated sales. Our businesses each could suffer significant setbacks in revenues and operating income if we lost one or more of our largest customers, or if our customers’ plans and/or markets should change significantly.

Physical Loss to Manufacturing Facilities

Although we insure ourselves against physical loss to our manufacturing facilities, including business interruption losses, natural or other disasters and accidents, including but not limited to fire, earthquake, damaging winds, floods, explosions and other casualties, operating results could be adversely affected if any of our manufacturing facilities became inoperable for an extended period of time due to these insured events or other non-insured events, including but not limited to acts of God, war or terrorism.

Development of New Products

Each of our businesses is actively involved in the development of new products, processes and services which are expected to contribute to our ongoing long-term growth and earnings. Consumer products using VersaShield fire retardant coatings have produced a limited amount of commercial sales to date. VersaShield’s fire retardant coatings market potential may be dependent on the stringency of federal and state regulatory requirements, which are difficult to predict. Further, our composite building products operation is producing and selling a new generation of decking products. Our composite building products operation is also developing products for use in various industrial applications. Our premium roofing products and specialty fabric technologies businesses are actively involved in developing and marketing new shingle, accessory and nonwoven specialty fabric products. If our developmental activities are not successful, regulatory requirements for fire retardant products are less stringent than currently predicted, market demand is less than expected, we experience unanticipated product performance issues or delays in achieving target product specifications, or we cannot provide the requisite financial and other resources to successfully commercialize such developments, the growth of future sales and earnings may be adversely affected.

Technological Changes

Each of our businesses is subject to the risks of technological changes and competition that is based on technology improvement or labor savings. These factors could affect the demand for or the relative cost of our technology, products and services, or the method and profitability of distribution or delivery of such technology, products and services.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

In addition to the risks inherent in our operations, we are exposed to financial, market, political and economic risks. The following discussion provides additional detail regarding our exposure to the risks of changing commodity prices and interest rates. We have no significant foreign exchange risk. Derivatives are held as part of a formally documented risk management program that contains limitations on terms and magnitude of commitments. Derivatives are held to mitigate uncertainty, volatility or to cover underlying exposures. No derivatives are held for speculation or trading purposes. We have from time to time entered into derivative transactions related to interest rate risk and our exposure to fluctuating prices of natural gas used in our manufacturing plants, as summarized in the following paragraphs.

We are required to purchase natural gas for use in our manufacturing facilities. These purchases expose us to the risk of higher natural gas prices. To hedge this risk, from time to time we may enter into hedge transactions to fix the price on a portion of our projected natural gas usage. In March 2006, we entered into a hedge transaction to fix the price on approximately 25% of our projected natural gas usage through September 2006. The contract value of the hedge transaction was $1,278,000 and the fair value at March 31, 2006 was immaterial in amount.

We use interest rate swaps to help maintain a reasonable balance between fixed and floating rate debt. We currently have two interest rate swaps in effect. We have entered into interest rate swaps to effectively convert the interest rate from fixed to floating on $85,000,000 of our outstanding debt at March 31, 2006. The net fair value of these swaps was $174,000 at March 31, 2006. Based on outstanding debt at March 31, 2006, our annual interest costs would increase or decrease $850,000 for each theoretical 1% increase or decrease in the floating interest rate.

Item 4. Controls and Procedures

	a)		Evaluation of Disclosure Controls and Procedures

			We completed an evaluation, under the supervision and with the participation of management, including the Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures pursuant to Exchange Act Rules 13a-15(e) and 15d-15(e) as of the end of the period covered by this report. Based upon that evaluation, the Chief Executive Officer and the Chief Financial Officer concluded that our disclosure controls and procedures are effective to ensure that information required to be disclosed by the company in the reports that it files or submits under the Exchange Act is (1) recorded, processed, summarized and reported within the time periods specified in applicable rules and forms and (2) accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, to allow timely discussions regarding required disclosures.

	b)		Changes in Internal Control Over Financial Reporting

			During the last fiscal quarter, there have been no changes in our internal controls over financial reporting or in other factors that have materially affected, or are reasonably likely to materially affect, these controls subsequent to the date of the evaluation, including any corrective actions with regard to significant deficiencies and material weaknesses.
