(Unless otherwise indicated, references to years or year-end refer to Griffon’s fiscal period ending September 30)

NOTE 1 – DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION

About Griffon Corporation

Griffon Corporation (the “Company” or “Griffon”), is a diversified management and holding company that conducts business through wholly-owned subsidiaries. Griffon oversees the operations of its subsidiaries, allocates resources among them and manages their capital structures. Griffon provides direction and assistance to its subsidiaries in connection with acquisition and growth opportunities as well as in connection with divestitures. In order to further diversify, Griffon also seeks out, evaluates and, when appropriate, will acquire additional businesses that offer potentially attractive returns on capital.

Griffon currently conducts its operations through three segments:

• Home & Building Products (“HBP”) consists of two companies, Ames True Temper, Inc. (“ATT”) and Clopay Building Products Company, Inc. (“CBP”):

- ATT is a global provider of non-powered landscaping products that make work easier for homeowners and professionals.

- CBP is a leading manufacturer and marketer of residential, commercial and industrial garage doors to professional installing dealers and major home center retail chains.

• Telephonics Corporation (“Telephonics”) designs, develops and manufactures high-technology integrated information, communication and sensor system solutions to military and commercial markets worldwide.

• Clopay Plastic Products Company, Inc. (“Plastics”) is an international leader in the development and production of embossed, laminated and printed specialty plastic films used in a variety of hygienic, health-care and industrial applications.

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, these financial statements do not include all the information and footnotes required by U.S. GAAP for complete financial statements. As such, they should be read with reference to Griffon’s Annual Report on Form 10-K for the year ended September 30, 2011, which provides a more complete explanation of Griffon’s accounting policies, financial position, operating results, business properties and other matters. In the opinion of management, these financial statements reflect all adjustments considered necessary for a fair statement of interim results. Griffon’s HBP operations are seasonal and the results of any interim period are not necessarily indicative of the results for the full year.

The condensed consolidated balance sheet information at September 30, 2011 was derived from the audited financial statements included in Griffon’s Annual Report on Form 10-K for the year ended September 30, 2011.

The consolidated financial statements include the accounts of Griffon Corporation and all subsidiaries. Intercompany accounts and transactions are eliminated on consolidation.

4

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reporting periods. These estimates may be adjusted due to changes in economic, industry or customer financial conditions, as well as changes in technology or demand. Significant estimates include allowances for doubtful accounts receivable and returns, net realizable value of inventories, restructuring reserves, valuation of goodwill and intangible assets, percentage of completion method of accounting, pension assumptions, useful lives associated with depreciation and amortization of intangible and fixed assets, warranty reserves, sales incentive accruals, stock based compensation assumptions, income taxes and tax valuation reserves, environmental reserves, legal reserves, insurance reserves and the valuation of discontinued assets and liabilities, and the accompanying disclosures. These estimates are based on management’s best knowledge of current events and actions Griffon may undertake in the future. Actual results may ultimately differ from these estimates.

Certain amounts in the prior year have been reclassified to conform to current year presentation.

NOTE 2 – FAIR VALUE MEASUREMENTS

The carrying values of cash and equivalents, accounts receivable, accounts and notes payable and revolving credit debt approximate fair value due to either the short-term nature of such instruments or the fact that the interest rate of the revolving credit debt is based upon current market rates.

The fair values of Griffon’s 2018 senior notes, and 2017 and 2023 4% convertible notes approximated $556,000, $91,000 and $532, respectively, on June 30, 2012. Fair values were based upon quoted market prices (level 1 inputs).

Insurance contracts with a value of $4,213 and trading securities with a value of $290 at June 30, 2012 are measured and recorded at fair value based upon quoted prices in active markets for identical assets (level 1 inputs).

Items Measured at Fair Value on a Recurring Basis

At June 30, 2012, Griffon had $1,250 of Australian dollar contracts at a weighted average rate of $0.97. The contracts, which protect Australia operations from currency fluctuations for U.S. dollar based purchases, do not qualify for hedge accounting. A fair value gain of $15 and $55 was recorded in other assets and to other income for the outstanding contracts, based on similar contract values (level 2 inputs), for the three and nine months ended June 30, 2012, respectively. The contracts expire in 30 to 90 days.

NOTE 3 – ACQUISITION

On October 17, 2011, Griffon acquired the pots and planters business of Southern Sales & Marketing Group, Inc. (“SSMG”) for $22,432. The acquired business, which markets its products under the Southern Patio brand name (“Southern Patio”), is a leading designer, manufacturer and marketer of landscape accessories. Southern Patio, which was integrated with ATT, had revenue exceeding $40,000 in 2011.

The accounts of the acquired company, after adjustments to reflect fair market values assigned to assets purchased from SSMG, have been included in the consolidated financial statements from the date of acquisition; acquired inventory was not significant. Griffon is in the process of finalizing the adjustment to the purchase price, if any, primarily related to working capital; accordingly, management has used their best estimate in the initial purchase price allocation as of the date of these financial statements.

Accumulated depreciation and amortization		(413,600	)		(380,571	)
Total	$	357,627		$	350,050

Depreciation and amortization expense for property, plant and equipment was $14,826 and $13,714 for the quarters ended June 30, 2012 and 2011, respectively, and $42,597 and $39,173 for the nine months ended June 30, 2012 and 2011, respectively.

No event or indicator of impairment occurred during the three and nine months ended June 30, 2012, which would require additional impairment testing of property, plant and equipment.

NOTE 6 – GOODWILL AND OTHER INTANGIBLES

The following table provides the changes in carrying value of goodwill by segment during the nine months ended June 30, 2012:

	At September 30, 2011		Goodwill from 2012 acquisitions		Other adjustments including currency translations			At June 30, 2012
Home & Building Products	$	265,147	$	4,655	$	—		$	269,802
Telephonics		18,545		—		—			18,545
Plastics		74,196		—		(4,627	)		69,569
Total	$	357,888	$	4,655	$	(4,627	)	$	357,916

The following table provides the gross carrying value and accumulated amortization for each major class of intangible assets:

	At June 30, 2012						At September 30, 2011
	Gross Carrying Amount		Accumulated Amortization		Average Life (Years)		Gross Carrying Amount		Accumulated Amortization
Customer relationships	$	165,576	$	19,126		25	$	155,602	$	13,862
Unpatented technology		6,495		2,188		11		6,534		1,749
Total amortizable intangible assets		172,071		21,314				162,136		15,611
Trademarks		79,419		—				76,664		—
Total intangible assets	$	251,490	$	21,314			$	238,800	$	15,611

Amortization expense for intangible assets subject to amortization was $2,006 and $1,987 for the quarters ended June 30, 2012 and 2011, respectively, and $6,071 and $5,905 for the nine months ended June 30, 2012 and 2011, respectively. The amortizable intangibles acquired in the Southern Patio acquisition will increase amortization in 2012 and forward by approximately $440 per year.

During the nine months ended June 30, 2012, there were changes in management at both Plastics and Telephonics. Management performed a qualitative assessment as to whether these changes affected these reporting units’ carrying value and concluded that it was more likely than not that the fair value of the units continue to be greater than their respective carrying values.

NOTE 7 – INCOME TAXES

The tax rate for the current quarter was a provision of 39.7%, compared to a benefit of 81.3% in the prior year quarter. The current quarter’s rate reflects the benefit from the release of previously established reserves for uncertain tax positions on conclusion of certain tax audits. The prior year effective rate included benefits arising on the filing of the tax returns in various jurisdictions and the impact of tax planning initiatives related to unremitted foreign earnings. Excluding discrete items, the current quarter’s rate was 50.5%, which reflects the impact of permanent differences not deductible in determining taxable income, mainly limited deductibility of restricted stock, as well as the impact of tax reserves and a change in earnings mix between domestic and non-domestic operations. Excluding discrete items, the prior year quarter’s rate was 77.7%, which reflected the combined effects of the nominal pretax income in the quarter with a forecast full year pretax loss for 2011, as well as fluctuations in the full year expected effective tax rate driven by changes in earnings mix between domestic and non-domestic operations.

7

The tax rate for the nine months ended June 30, 2012 was a provision of 45.0%, compared to a benefit of 48.5% in the prior year. The current year rate reflects the benefit from the release of previously established reserves for uncertain tax positions on conclusion of certain tax audits. The prior year effective rate included benefits arising in connection with the retroactively extended research tax credit signed into law on December 22, 2010, the filing of tax returns in various jurisdictions, and the impact of tax planning initiatives related to unremitted foreign earnings. Excluding discrete items, the current year rate was 51.6%, which reflected the impact of permanent differences that are not deductible in determining taxable income, mainly limited deductibility of restricted stock, as well as the impact of tax reserves and a change in earnings mix between domestic and non-domestic operations. Excluding discrete items, the prior year rate was a benefit of 27.0% and reflected the impact of permanent differences not deductible in determining taxable income as well as the impact of tax reserves and changes in earnings mix.

(a)	On March 17, 2011, in an unregistered offering through a private placement under Rule 144A, Griffon issued, at par, $550,000 of 7.125% Senior Notes due in 2018; interest is payable semi-annually. On August 9, 2011, Griffon exchanged all of the Senior Notes for substantially identical Senior Notes registered under the Securities Act of 1933 (“Senior Notes”), via an exchange offer.
	The Senior Notes can be redeemed prior to April 1, 2014 at a price of 100% of principal plus a make-whole premium and accrued interest; on or after April 1, 2014, the Senior Notes can be redeemed at a certain price (declining from 105.344% of principal on or after April 1, 2014 to 100% of principal on or after April 1, 2017), plus accrued interest. Proceeds from the Senior Notes were used to pay down the outstanding borrowings under a senior secured term loan facility and two senior secured revolving credit facilities of certain of the Company’s subsidiaries. The Senior Notes are senior unsecured obligations of Griffon guaranteed by certain domestic subsidiaries, and are subject to certain covenants, limitations and restrictions.
	On March 18, 2011, Griffon entered into a five-year $200,000 Revolving Credit Facility (“Credit Agreement”), which includes a letter of credit sub-facility with a limit of $50,000, a multi-currency sub-facility of $50,000 and a swingline sub-facility with a limit of $30,000. Borrowings under the Credit Agreement may be repaid and re-borrowed at any time, subject to final maturity of the facility or the occurrence of a default or event of default under the Credit Agreement. Interest is payable on borrowings at either a LIBOR or base rate benchmark rate plus an applicable margin, which will adjust based on financial performance. The margins are 1.75% for base rate loans and 2.75% for LIBOR loans, in each case without a floor. The Credit Agreement has certain financial maintenance tests including a maximum total leverage ratio, a maximum senior secured leverage ratio and a minimum interest coverage ratio as well as customary affirmative and negative covenants and events of default. The Credit Agreement also includes certain restrictions, such as limitations on the incurrence of indebtedness and liens and the making of restricted payments and investments. Borrowings under the Credit Agreement are guaranteed by certain domestic subsidiaries and are secured, on a first priority basis, by substantially all assets of the Company and the guarantors.
	At June 30, 2012, there were $21,516 of standby letters of credit outstanding under the Credit Agreement; $178,484 was available for borrowing at that date.

(b)	On December 21, 2009, Griffon issued $100,000 principal of 4% convertible subordinated notes due 2017 (the “2017 Notes”). The initial conversion rate of the 2017 Notes was 67.0799 shares of Griffon’s common stock per $1,000 principal amount of notes, corresponding to an initial conversion price of $14.91 per share, a 23% conversion premium over the $12.12 closing price on December 15, 2009. When a cash dividend is declared that would result in an adjustment to the conversion ratio of less than 1%, any adjustment to the conversion ratio is deferred until the first to occur of (i) actual conversion, (ii) the 42nd trading day prior to maturity of the notes, and (iii) such time as the cumulative adjustment equals or exceeds 1%. As of September 25, 2012, aggregate dividends of $0.08 per share would result in a cumulative change in the conversion rate of approximately 0.9%. Griffon used 8.75% as the nonconvertible debt-borrowing rate to discount the 2017 Notes and will amortize the debt discount through January 2017. At issuance, the debt component of the 2017 Notes was $75,437 and debt discount was $24,563. At June 30, 2012 and September 30, 2011, the 2017 Notes had a capital in excess of par component, net of tax, of $15,720.
(c)	On December 20, 2010, Griffon entered into two second lien real estate mortgages to secure new loans totaling $11,834. The loans mature in February 2016, are collateralized by the related properties and are guaranteed by Griffon. The loans bear interest at a rate of LIBOR plus 3% with the option to swap to a fixed rate.
	Griffon has other real estate mortgages, collateralized by real property, which bear interest at 6.3% and mature in 2016. On October 3, 2011, the mortgage at Russia, Ohio was paid in full, on maturity.
(d)	Griffon’s Employee Stock Ownership Plan (“ESOP”) entered into a loan agreement in August 2010 to borrow $20,000 over a one-year period. The proceeds were used to purchase 1,874,737 shares of Griffon common stock in the open market for $19,973. The loan bears interest at a) LIBOR plus 2.5% or b) the lender’s prime rate, at Griffon’s option. In November 2011, Griffon exercised an option to convert the outstanding loan to a five-year term loan; principal is payable in quarterly installments of $250, beginning December 2011, with a balloon payment of $15,223 due at maturity (November 2016). The loan is secured by shares purchased with the proceeds of the loan, and repayment is guaranteed by Griffon. At June 30, 2012, $19,223 was outstanding.
	In addition, the ESOP has a loan agreement, guaranteed by Griffon, which requires quarterly principal payments of $156 and interest through the extended expiration date of December 2013 at which time the $3,125 balance of the loan, and any outstanding interest, will be payable. The primary purpose of this loan was to purchase 547,605 shares of Griffon’s common stock in October 2008. The loan is secured by shares purchased with the proceeds of the loan, and repayment is guaranteed by Griffon. The loan bears interest at rates based upon the prime rate or LIBOR. At June 30, 2012, $3,906 was outstanding.
(e)	In October 2006, CBP entered into a capital lease totaling $14,290 for real estate in Troy, Ohio. The lease matures in 2021, bears interest at a fixed rate of 5.1%, is secured by a mortgage on the real estate and is guaranteed by Griffon.
(f)	At June 30, 2012 and September 30, 2011, Griffon had $532 of 4% convertible subordinated notes due 2023 (the “2023 Notes”) outstanding. Holders of the 2023 Notes may require Griffon to repurchase all or a portion of their 2023 Notes on July 18, 2013 and 2018, if Griffon’s common stock price is below the conversion price of the 2023 Notes, as well as upon a change in control. An adjustment to the conversion rate will be required as the result of payment of a cash dividend only if such adjustment would be greater than 1% (or at such time as the cumulative impact on the conversion rate reaches 1% in the aggregate). As of September 25, 2012, aggregate dividends of $0.08 per share would result in a cumulative change in the conversion rate of approximately 0.9%. At June 30, 2012 and September 30, 2011, the 2023 Notes had no capital in excess of par value component as substantially all of these notes were put to Griffon at par and settled in July 2010.

(g)	In November 2010, Clopay Europe GMBH (“Clopay Europe”) entered into a €10,000 revolving credit facility and a €20,000 term loan. The facility accrues interest at Euribor plus 2.1% per annum, and the term loan accrues interest at Euribor plus 2.2% per annum. The revolving facility matures in November 2012, but is renewable upon mutual agreement with the bank. In July 2011, the full €20,000 was drawn on the Term Loan, with a portion of the proceeds used to repay borrowings under the revolving credit facility. The term loan is payable in ten equal quarterly installments which began in September 2011, with maturity in December 2013. Under the term loan, Clopay Europe is required to maintain a certain minimum equity to assets ratio and keep leverage below a certain level, defined as the ratio of total debt to EBITDA. At June 30, 2012, there was €1,000 borrowed on the revolving credit with €9,000 available for borrowing.
(h)	In February 2012, Clopay do Brazil, a subsidiary of Plastics, borrowed $4,000 at a rate of 104.5% of Brazilian CDI. The loan was used to refinance existing loans and is collateralized by accounts receivable and a 50% guaranty by Plastics and is to be repaid in four equal, semi-annual installments of principal plus accrued interest beginning in August 2012. Clopay do Brazil also maintains a line of credit of approximately $1,700. Interest on borrowings accrue at a rate of Brazilian CDI plus 6.0%. At June 30, 2012 there was approximately $1,346 borrowed under the line.
(i)	In connection with the ATT acquisition, Clopay Ames True Temper Holding Corp. (“Clopay Ames”), a subsidiary of Griffon, entered into a $375,000 secured term Loan (“Term Loan”) and a $125,000 asset based lending agreement (“ABL”).
	On November 30, 2010, Clopay Ames, as required under the Term Loan agreement, entered into an interest rate swap on a notional amount of $200,000 of the Term Loan. The agreement fixed the LIBOR component of the Term Loan interest rate at 2.085% for the notional amount of the swap.
	On March 17, 2011, the Term Loan and swap were terminated, and on March 18, 2011, the ABL was terminated, in connection with the issuance of the Senior Notes and Credit Agreement.
(j)	In March 2008, Telephonics entered into a credit agreement with JPMorgan Chase Bank, N.A., as administrative agent, and the lenders party thereto, pursuant to which the lenders agreed to provide a five-year, revolving credit facility of $100,000 (the “TCA”). The TCA terminated in connection with the Credit Agreement.
(k)	Includes capital leases.

At June 30, 2012, Griffon and its subsidiaries were in compliance with the terms and covenants of its credit and loan agreements.

During the second quarter of 2011, in connection with the termination of the Term Loan, ABL and Telephonics credit agreement, Griffon recorded a $26,164 loss on extinguishment of debt consisting of $21,617 of deferred financing charges and original issuer discounts, a call premium of $3,703 on the Term Loan, and $844 of swap and other breakage costs.

NOTE 9 — SHAREHOLDERS’ EQUITY

During the first, second and third quarters of 2012, the Board of Directors approved three quarterly cash dividends of $0.02 per common share, which were paid on December 27, 2011, March 27, 2012 and June 26, 2012, to holders of common stock as of close of business on November 29, 2011, February 28, 2012 and May 29, 2012, respectively. $1,190 and $3,564 was recorded to retained earnings for the dividend for the three and nine months ended June 30, 2012, respectively. Dividends paid on allocated shares in the ESOP were used to pay down the ESOP loan and were recorded as a reduction in expense. A dividend payable was established for the holders of restricted shares; such payable will be released upon vesting of the underlying restricted shares.

11

On August 2, 2012, the Board of Directors declared a fourth quarterly cash dividend of $0.02 per share, payable on September 25, 2012 to shareholders of record as of the close of business on August 28, 2012.

Griffon expenses the fair value of equity compensation grants over the related vesting period. Compensation cost related to stock-based awards with graded vesting are amortized using the straight-line attribution method.

In February 2011, shareholders approved the Griffon Corporation 2011 Equity Incentive Plan (“Incentive Plan”) under which awards of performance shares, performance units, stock options, stock appreciation rights, restricted shares, deferred shares and other stock-based awards may be granted. Options granted under the Incentive Plan may be either “incentive stock options” or nonqualified stock options, generally expire ten years after the date of grant and must be granted at an exercise price of not less than 100% of the fair market value at the date of grant. The maximum number of shares of common stock available for award under the Incentive Plan is 3,000,000 (600,000 of which may be issued as incentive stock options) plus any shares underlying awards outstanding on the effective date of the Incentive Plan under the 2006 Incentive Plan that are subsequently cancelled or forfeited. As of June 30, 2012, 1,770,509 shares were available for grant.

All grants outstanding under the Griffon Corporation 2001 Stock Option Plan, 2006 Equity Incentive Plan and Outside Director Stock Award Plan will continue under their terms; no additional awards will be granted under such plans.

During the first quarter of 2012, Griffon granted 309,500 restricted shares with three-year cliff vesting, 191,000 of which are also subject to certain performance conditions, with a total fair value of $2,881, or a weighted average fair value of $9.31 per share.

During the second quarter of 2012, Griffon granted 110,000 restricted shares, 82,500 of which are three-year cliff vesting and 27,500 of which vest equally over 3 years; 37,500 of the 110,000 shares are subject to certain performance conditions. The total fair value of these grants is $1,119, or a weighted average fair value of $9.83 per share.

During the third quarter of 2012, Griffon granted 2,000 restricted shares with three-year cliff vesting. The total fair value of these grants is $19, or a weighted average fair value of $9.33 per share.

During the second quarter of 2011, Griffon granted 590,000 performance shares. Prior to the change in the terms of the grant, the performance shares had a fair value of $7,346, or a weighted average fair value of $12.45 per share, and cliff vested when either Griffon’s common stock closed at or above $16 per share for twenty consecutive trading days or 7 years from the date of grant, whichever came first. In January 2012, the terms of the grant were modified such that the price of Griffon common stock must close at or above $16 per share for thirty consecutive trading days on or prior to January 10, 2016 in order for the shares to vest; otherwise, the shares will be forfeited. The unamortized portion of the original fair value of approximately $6,400 will be expensed over the new service period of 32 months beginning January 2012.

For the three and nine months ended June 30, 2012, stock based compensation expense totaled $2,691 and $7,599, respectively. For the three and nine months ended June 30, 2011, stock based compensation expense totaled $2,120 and $6,767, respectively.

In August 2011, Griffon’s Board of Directors authorized the repurchase of up to $50,000 of Griffon’s outstanding common stock. Under this repurchase program, the Company may, from time to time, purchase shares of its common stock, depending upon market conditions, in open market or privately negotiated transactions, including pursuant to a 10b5-1 plan. In the first quarter of 2012, Griffon purchased 283,400 shares of common stock, for a total of $2,351, or $8.29 per share. In the third quarter of 2012, Griffon purchased 417,667 shares of common stock, for a total of $3,320, or $7.95 per share; in total, Griffon has purchased 866,446 shares of common stock, for a total of $6,980, or $8.06 per share, under this repurchase program. $43,020 remains under the $50,000 authorization. Subsequent to June 30, 2012, Griffon purchased 66,199 shares of common stock, for a total of $560, or $8.47 per share.

NOTE 10 – EARNINGS PER SHARE (EPS)

Basic EPS was calculated by dividing income available to common shareholders by the weighted average number of shares of common stock outstanding during the period. Diluted EPS was calculated by dividing income available to common shareholders by the weighted average number of shares of common stock outstanding plus additional common shares that could be issued in connection with stock based compensation. The 2023 Notes and the 2017 Notes were anti-dilutive due to the conversion price being greater than the weighted-average stock price during the periods presented. Due to the net loss during the nine months ended June 30, 2011, the incremental shares from stock based compensation are anti-dilutive.

The following table is a reconciliation of the share amounts (in thousands) used in computing earnings per share:

	Three Months Ended June 30,				Nine Months Ended June 30,
	2012		2011		2012		2011
Weighted average shares outstanding - basic		56,034		59,606		56,032		59,387
Incremental shares from stock based compensation		1,461		919		1,279		—
Weighted average shares outstanding - diluted		57,495		60,525		57,311		59,387
Anti-dilutive options excluded from diluted EPS computation		963		1,200		1,202		1,200
Anti-dilutive restricted stock excluded from diluted EPS computation		—		850		—		850

Griffon has the intent and ability to settle the principal amount of the 2017 Notes in cash, as such, the potential issuance of shares related to the principal amount of the 2017 Notes does not affect diluted shares.

NOTE 11 – BUSINESS SEGMENTS

Griffon’s reportable business segments are as follows:

• HBP is a leading manufacturer and marketer of residential, commercial and industrial garage doors to professional installing dealers and major home center retail chains, as well as a global provider of non-powered landscaping products that make work easier for homeowners and professionals.

NOTE 18 – WARRANTY LIABILITY

Telephonics offers warranties against product defects for periods generally ranging from one to two years, depending on the specific product and terms of the customer purchase agreement. Typical warranties require Telephonics to repair or replace the defective products during the warranty period at no cost to the customer. At the time revenue is recognized, Griffon records a liability for warranty costs, estimated based on historical experience and periodically assesses its warranty obligations and adjusts the liability as necessary. ATT offers an express limited warranty for a period of ninety days on all products unless otherwise stated on the product or packaging from the date of original purchase.

Changes in Griffon’s warranty liability, included in Accrued liabilities, were as follows:

NOTE 19 — COMMITMENTS AND CONTINGENCIES

Legal and environmental
Department of Environmental Conservation of New York State (“DEC”), with ISC Properties, Inc. Lightron Corporation (“Lightron”), a wholly-owned subsidiary of Griffon, once conducted operations at a location in Peekskill in the Town of Cortlandt, New York (the “Peekskill Site”) owned by ISC Properties, Inc. (“ISC”), a wholly-owned subsidiary of Griffon. ISC sold the Peekskill Site in November 1982.

Subsequently, Griffon was advised by the DEC that random sampling at the Peekskill Site and in a creek near the Peekskill Site indicated concentrations of solvents and other chemicals common to Lightron’s prior plating operations. ISC then entered into a consent order with the DEC in 1996 (the “Consent Order”) to perform a remedial investigation and prepare a feasibility study. After completing the initial remedial investigation pursuant to the Consent Order, ISC was required by the DEC, and did conduct accordingly over the next several years, supplemental remedial investigations, including soil vapor investigations, under the Consent Order.

18

In April 2009, the DEC advised ISC’s representatives that both the DEC and the New York State Department of Health had reviewed and accepted an August 2007 Remedial Investigation Report and an Additional Data Collection Summary Report dated January 30, 2009. With the acceptance of these reports, ISC completed the remedial investigation required under the Consent Order and was authorized, accordingly, by the DEC to conduct the Feasibility Study required by the Consent Order. Pursuant to the requirements of the Consent Order and its obligations thereunder, ISC, without acknowledging any responsibility to perform any remediation at the Site, submitted to the DEC in August 2009, a draft feasibility study which recommended for the soil, groundwater and sediment medias, remediation alternatives having a current net capital cost value, in the aggregate, of approximately $5,000. In February 2011, DEC advised ISC it has accepted and approved the feasibility study. Accordingly, ISC has no further obligations under the consent order.

Upon acceptance of the feasibility study, DEC issued a Proposed Remedial Action Plan (“PRAP”) that sets forth the proposed remedy for the site. The PRAP accepted the recommendation contained in the feasibility study for remediation of the soil and groundwater medias, but selected a different remediation alternative for the sediment medium. The approximate cost and the current net capital cost value of the remedy proposed by DEC in the PRAP is approximately $10,000. After receiving public comments on the PRAP, the DEC issued a Record of Decision (“ROD”) that set forth the specific remedies selected and responded to public comments. The remedies selected by the DEC in the ROD are the same remedies as those set forth in the PRAP.

It is now expected that DEC will enter into negotiations with potentially responsible parties to request they undertake performance of the remedies selected in the ROD, and if such parties do not agree to implement such remedies, then the State may use State Superfund money to remediate the Peekskill site and seek recovery of costs from such parties. Griffon does not acknowledge any responsibility to perform any remediation at the Peekskill Site.

Improper Advertisement Claim involving UnionTools Products. Since December 2004, a customer of ATT has been named in various litigation matters relating to certain UnionTools products. The plaintiffs in those litigation matters have asserted causes of action against the customer of ATT for improper advertisement to end consumers. The allegations suggest that advertisements led the consumers to believe that Union Tools’ hand tools were wholly manufactured within boundaries of the United States. The complaints assert various causes of action against the customer of ATT under federal and state law, including common law fraud. At some point, likely once the litigation against the customer of ATT ends, the customer may seek indemnity (including recovery of its legal fees and costs) against ATT for an unspecified amount. Presently, ATT cannot estimate the amount of loss, if any, if the customer were to seek legal recourse against ATT.

Department of Environmental Conservation of New York State, regarding Frankfort, NY site. During fiscal 2009, an underground fuel tank with surrounding soil contamination was discovered at the Frankfort, N.Y. site which is the result of historical facility operations prior to ATT’s ownership. While ATT was actively working with the DEC and the New York State Department of Health to define remediation requirements relative to the underground fuel tank, the DEC took the position that ATT was responsible to remediate other types of contamination on the site. After negotiations with the DEC, on August 15, 2011, ATT executed an Order on Consent with the DEC. The Order is without admission or finding of liability or acknowledgement that there has been a release of hazardous substances at the site. Importantly, the Order does not waive any rights that ATT has under a 1991 Consent Judgment entered into between the DEC and a predecessor of ATT relating to the site. The Order requires that ATT identify Areas of Concern at the site, and formulate a strategy to investigate and remedy both on and off site conditions in compliance with applicable environmental law. At the conclusion of the remedy phase of the remediation to the satisfaction of the DEC, the DEC will issue a Certificate of Completion. On September 26, 2011 ATT submitted a Records Search Report to DEC and on October 24, 2011 filed the draft Remedial Investigation Work Plan (“RIWP”) completing the first two steps under the Order. DEC responded to ATT’s draft work plan and requested that ATT submit an amended work plan reflecting certain changes. On June 1, 2012, ATT submitted to DEC a revised RIWP and Proposed Interim Remedial Measure Work Plan (“IRM”) for the demolition of various buildings at the site. DEC is currently reviewing both submissions.

U.S. Government investigations and claims

Defense contracts and subcontracts, including Griffon’s contracts and subcontracts, are subject to audit and review by various agencies and instrumentalities of the United States government, including, among others, the Defense Contract Audit Agency (“DCAA”) and the Department of Justice, which has responsibility for asserting claims on behalf of the U.S. government. In addition to ongoing audits, pursuant to an administrative subpoena Griffon is currently providing information to the U.S. Department of Defense Office of the Inspector General. No claim has been asserted against Griffon, and Griffon is unaware of any material financial exposure in connection with the Inspector General’s inquiry.

In general, departments and agencies of the U.S. Government have the authority to investigate various transactions and operations of Griffon, and the results of such investigations may lead to administrative, civil or criminal proceedings, the ultimate outcome of which could be fines, penalties, repayments or compensatory or treble damages. U.S. Government regulations provide that certain findings against a contractor may lead to suspension or debarment from future U.S. Government contracts or the loss of export privileges for a company or an operating division or subdivision. Suspension or debarment could have material adverse effect on Telephonics because of its reliance on government contracts.

General legal

Griffon is a party to legal proceedings arising in the ordinary course of business and is subject to various laws and regulations relating to the protection of the environment. Management believes, based on facts presently known to it, that the resolution of the matters above and such other matters will not have a material adverse effect on Griffon’s consolidated financial position, results of operations or cash flows.

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

BUSINESS OVERVIEW (in thousands, except per share data)

Griffon Corporation (the “Company” or “Griffon”), is a diversified management and holding company that conducts business through wholly-owned subsidiaries. Griffon oversees the operations of its subsidiaries, allocates resources among them and manages their capital structures. Griffon provides direction and assistance to its subsidiaries in connection with acquisition and growth opportunities as well as in connection with divestitures. In order to further diversify, Griffon also seeks out, evaluates and, when appropriate, will acquire additional businesses that offer potentially attractive returns on capital.

Griffon currently conducts its operations through three segments:

• Home & Building Products (“HBP”) consists of two companies, Ames True Temper, Inc. (“ATT”) and Clopay Building Products Company, Inc. (“CBP”):

- ATT is a global provider of non-powered landscaping products that make work easier for homeowners and professionals.

- CBP is a leading manufacturer and marketer of residential, commercial and industrial garage doors to professional installing dealers and major home center retail chains.

• Telephonics Corporation (“Telephonics”) designs, develops and manufactures high-technology integrated information, communication and sensor system solutions to military and commercial markets worldwide.

• Clopay Plastic Products Company, Inc. (“Plastics”) is an international leader in the development and production of embossed, laminated and printed specialty plastic films used in a variety of hygienic, health-care and industrial applications. 

On October 17, 2011, Griffon acquired the pots and planters business of Southern Sales & Marketing Group, Inc. for $22,432. The acquired business, which markets its products under the Southern Patio brand name (“Southern Patio”), is a leading designer, manufacturer and marketer of landscape accessories. Southern Patio, which was integrated with ATT, had revenue exceeding $40,000 in 2011; acquired inventory was not significant.

Southern Patio’s results of operations are not included in the Griffon consolidated balance sheet, statement of operations or cash flows, or footnotes relating thereto prior to October 17, 2011.

OVERVIEW

Revenue for the quarter ended June 30, 2012 was $480,246, compared to $455,282 in the prior year quarter. Net income was $9,048 or $0.16 per share, compared to $4,872 or $0.08 per share, in the prior year quarter.

The current year quarter included a discrete tax benefit of $1,626, or $0.03 per share.

The prior year quarter included:
	-	Restructuring charges of $2,118 ($1,377, net of tax or $0.02 per share); and
	-	Discrete tax benefits and the quarter impact for updates to the annual effective rate, net, of $3,077 or $0.05 per share.

Excluding these items from the respective quarters, net income would have been $7,422 or $0.13 per share in the current quarter compared to $3,172 or $0.05 per share in the prior year quarter.

29

Revenue for the nine months ended June 30, 2012 was $1,413,709, compared to $1,345,813 in the prior year. Net income was $13,563 or $0.24 per share, compared to a loss of $10,809 or $0.18 per share, in the prior year. Results for the nine months ended June 30, 2012 results included:
	-	Restructuring and related charges of $1,795 ($1,167, net of tax or $0.02 per share);
	-	Acquisition costs of $178 ($116, net of tax or $0.00 per share): and
	-	Discrete tax benefits of $1,626 or $0.03 per share.

Results for the nine months ended June 30, 2011 included:
	-	Charges related to debt extinguishment of $26,164 ($16,813, net of tax or $0.28 per share);
	-	Increased cost of goods related to the sale of inventory recorded at fair value in connection with acquisition accounting for ATT of $15,152 ($9,849, net of tax or $0.17 per share);
	-	Restructuring charges of $4,723 ($3,070, net of tax or $0.05 per share); and
	-	Discrete tax benefits of $4,513 or $0.08 per share.

Excluding these items from both periods, Net income would have been $13,220 or $0.23 per share, compared to $14,410 or $0.24 per share in the prior year.

Griffon evaluates performance based on Earnings per share and Net income (loss) excluding restructuring charges, gain (loss) from debt extinguishment, discrete tax items, acquisition costs and costs related to the fair value of inventory for acquisitions. Griffon believes this information is useful to investors. The following table provides a reconciliation of Earnings (loss) per share and Net income (loss) to Adjusted earnings per share and Adjusted net income:

For the quarter ended June 30, 2012, revenue increased $22,978, or 11%, compared to the prior year quarter. ATT revenue increased 14% primarily due to the inclusion of Southern Patio. For the quarter, CBP revenue increased 7% primarily due to higher volume and favorable mix.

31

For the quarter ended June 30, 2012, Segment operating profit was $17,482 compared to $13,512 in the prior year quarter with the increase resulting primarily from the impact of higher volume, favorable mix, improved production efficiencies, lower restructuring charges and the inclusion of Southern Patio’s operating profit in the current quarter’s results, partially offset by the impact of somewhat higher material costs.

For the nine months ended June 30, 2012, revenue increased $27,374, or 4%. CBP revenue increased 7% due to increased volume and favorable mix, while ATT revenue increased 2% primarily due to the inclusion of Southern Patio in the current year results, partially offset by the impact of reduced volume of snow tool sales, driven by the absence of snow throughout much of the U.S. and Canada this past winter.

For the nine months ended June 30, 2012, Segment operating profit was $35,412 compared to $18,820 in the prior year. Excluding the impact of the fair value write-up of acquired inventory sold of $15,152, Segment operating profit increased $1,440 from the prior year primarily due to higher volume, favorable mix, improved production efficiencies, lower restructuring charges and the inclusion of Southern Patio’s operating profit in the current period’s results, partially offset by the impact of somewhat higher material and fuel costs and lower snow tool volume.

In both periods, restructuring and other related charges primarily related to facilities and compensation costs. The current year acquisition costs related to the Southern Patio acquisition.

For the quarter ended June 30, 2012, revenue decreased $2,414 compared to the prior year quarter. For the quarters ended June 30, 2012 and 2011, revenue included $2,733 and $5,760, respectively, related to revenue for the Counter Remote Control Improvised Explosive Device Electronic Warfare 3.1 (“CREW 3.1”) program where Telephonics serves as a contract manufacturer. Excluding CREW 3.1 from both quarters, revenue increased 1% over the prior year quarter primarily attributable to Light Airborne Multi-purpose Systems Multi Mode Radar (“LAMPS MMR”) ($13,722) and Identification Friend or Foe (“IFF”) ($6,568), partially offset by declines in revenue attributable to the C-17 program ($5,534), Maritime Radars ($4,851) and Ground Surveillance Radars (“GSR”) ($2,625).

For the quarter ended June 30, 2012, Segment operating profit increased $4,388, or 45%, and operating profit margin increased 460 basis points in comparison to the prior year quarter. The increase was primarily due to higher gross profits from program mix, benefits from the prior year voluntary early retirement plan and other restructuring and manufacturing efficiencies, partially offset by higher selling, general and administrative expenses due to the timing of proposal activities and restructuring costs. In the prior year quarter, Telephonics recognized $603 of restructuring charges in connection with the consolidation of management of its Electronic Systems and Communication Systems operating units; such charges are all personnel related.

For the nine months ended June 30, 2012, revenue increased $4,287, or 1%, compared to the prior year. For the nine months ended June 30, 2012 and 2011, revenue included $22,255 and $33,032, respectively, related to revenue for CREW 3.1; excluding CREW 3.1 revenue from both periods, current period revenue increased 5% over the prior year period primarily attributable to LAMPS MMR ($12,227), IFF ($8,300) and NETCOM communication products ($8,202), partially offset by declines in revenue attributable to the C-17 ($8,324) and CP-140 ($3,178) programs.

32

For the nine months ended June 30, 2012, Segment operating profit increased by $8,528, or 27%, and operating profit margin increased 260 basis points from the prior year. The increase was primarily due to higher gross profits from increased revenue, program mix, benefits from the prior year voluntary early retirement plan and other restructuring, and manufacturing efficiencies, partially offset by higher selling, general and administrative expenses due to the timing of proposal activities and the restructuring charge. In the first quarter, Telephonics recognized $1,522 of restructuring and other related charges, primarily for one-time termination benefits and other personnel costs, in conjunction with changes to its organizational structure.

During the current quarter, Telephonics was awarded several new contracts and received incremental funding on current contracts totaling $88,700. Contract backlog was $422,000 at June 30, 2012 with 69% expected to be realized in the next 12 months. Backlog was $417,000 at September 30, 2011 and $442,000 at June 30, 2011. Backlog is defined as unfilled firm orders for products and services for which funding has been both authorized and appropriated by the customer or Congress, in the case of the U.S. government agencies.

For the quarter ended June 30, 2012, revenue increased $4,400, or 3%, compared to the prior year quarter primarily due to higher unit volumes (12%) and the pass through of higher resin costs in customer selling prices (1%), partially offset by the unfavorable impact of foreign exchange translation (8%) and mix (2%). Plastics adjusts customer selling prices based on underling resin costs on a delayed basis.

For the quarter ended June 30, 2012, Segment operating profit increased $3,811, compared to the prior year quarter. The increase was primarily driven by higher unit volumes and improved efficiency on capital initiatives which were implemented in Germany and Brazil in the prior year, partially offset by the impact of higher resin costs and higher selling, general and administrative expenses.

For the nine months ended June 30, 2012, Plastics revenue increased $36,235, or 9%, compared to the prior year period, primarily due to higher unit volumes (13%) and the pass through of higher resin costs in customer selling prices (1%), partially offset by the unfavorable impact of foreign exchange translation (4%) and mix (1%).

For the nine months ended June 30, 2012, Segment operating profit decreased $1,128, or 13%, compared to the prior year mainly due to the previously disclosed start up costs related to expanded capacity initiatives in both Germany and Brazil; in both operations, such start up costs have included higher than normal levels of scrap. There have been no significant disruptions in customer service in connection with the scaling up of production of the newly installed assets. Improvements in operations in the newly expanded locations are proceeding; however, the locations are contending with challenging market conditions, and higher resin costs. The Company trended towards normal efficiency levels in the quarter and is expected to again in the fourth quarter.

Unallocated

For the quarter ended June 30, 2012, unallocated amounts totaled $7,253 compared to $7,781 in the prior year; the decrease was primarily related to cost of management incentive plans. For the nine months ended June 30, 2012, unallocated amounts totaled $20,041 compared to $19,468 in the prior year; the increase was primarily related to higher investment income in the prior year.

33

Segment Depreciation and Amortization

Segment depreciation and amortization increased $1,126 and $3,556, respectively, for the three and nine-month periods ended June 30, 2012 in comparison to the comparable prior year periods primarily due to capital spending in 2011.

Other income (expense)

For the quarters ended June 30, 2012 and 2011, Other income included net foreign exchange gain (loss) of ($707) and $24, respectively, and $38 and $311, respectively, of investment expense.

For the nine months ended June 30, 2012 and 2011, Other income included net foreign exchange loss of $1,375 and $3, respectively, and $134 and $996, respectively, of investment income.

During 2011, in connection with the termination of the Term Loan, ABL and Telephonics credit agreement, Griffon recorded a $26,164 loss on extinguishment of debt consisting of $21,617 of deferred financing charges and original issuer discounts, a call premium of $3,703 on the Term Loan, and $844 of swap and other breakage costs.

Provision for income taxes

The tax rate for the current quarter was a provision of 39.7%, compared to a benefit of 81.3% in the prior year quarter. The current quarter’s rate reflects the benefit from the release of previously established reserves for uncertain tax positions on conclusion of certain tax audits. The prior year effective rate included benefits arising on the filing of the tax returns in various jurisdictions and the impact of tax planning initiatives related to unremitted foreign earnings. Excluding discrete items, the current quarter’s rate was 50.5%, which reflects the impact of permanent differences not deductible in determining taxable income, mainly limited deductibility of restricted stock, as well as the impact of tax reserves and a change in earnings mix between domestic and non-domestic operations. Excluding discrete items, the prior year quarter’s rate was 77.7%, which reflected the combined effects of the nominal pretax income in the quarter with a forecast full year pretax loss for 2011, as well as fluctuations in the full year expected effective tax rate driven by changes in earnings mix between domestic and non-domestic operations.

The tax rate for the nine months ended June 30, 2012 was a provision of 45.0%, compared to a benefit of 48.5% in the prior year. The current year rate reflects the benefit from the release of previously established reserves for uncertain tax positions on conclusion of certain tax audits. The prior year effective rate included benefits arising in connection with the retroactively extended research tax credit signed into law on December 22, 2010, the filing of tax returns in various jurisdictions, and the impact of tax planning initiatives related to unremitted foreign earnings. Excluding discrete items, the current year rate was 51.6%, which reflected the impact of permanent differences that are not deductible in determining taxable income, mainly limited deductibility of restricted stock, as well as the impact of tax reserves and a change in earnings mix between domestic and non-domestic operations. Excluding discrete items, the prior year rate was a benefit of 27.0% and reflected the impact of permanent differences not deductible in determining taxable income as well as the impact of tax reserves and changes in earnings mix.

Stock based compensation

For the three and nine months ended June 30, 2012, stock based compensation expense totaled $2,691 and $7,599, respectively. For the three and nine months ended June 30, 2011, stock based compensation expense totaled $2,120 and $6,767, respectively.

Discontinued operations – Installation Services

There was no revenue or income from discontinued operations of the Installation Services’ business for the three and nine months ended June 30, 2012 and 2011.

LIQUIDITY AND CAPITAL RESOURCES

Management assesses Griffon’s liquidity in terms of its ability to generate cash to fund its operating, investing and financing activities. Significant factors affecting liquidity are: cash flows from operating activities, capital expenditures, acquisitions, dispositions, bank lines of credit and the ability to attract long-term capital with satisfactory terms. Griffon remains in a strong financial position with sufficient liquidity available for reinvestment in existing businesses and strategic acquisitions while managing its capital structure on both a short-term and long-term basis.

The following table is derived from the Consolidated Statements of Cash Flows:

	Nine Months Ended June 30,
Cash Flows from Continuing Operations
(in thousands)	2012			2011
Net Cash Flows Provided by (Used In):
Operating activities	$	30,347		$	13,055
Investing activities		(79,846	)		(60,621	)
Financing activities		(20,255	)		123,843

Cash provided by continuing operations for the nine months ended June 30, 2012 were $30,347 compared to $13,055 in the prior year. Current assets net of current liabilities, excluding short-term debt and cash, increased to $405,113 at June 30, 2012 compared to $366,511 at September 30, 2011, primarily as a result of a decrease in accounts payable and accrued liabilities.

During the nine months ended June 30, 2012, Griffon used cash for investing activities of $79,846 compared to $60,621 in the prior year; the increase was primarily due to the acquisition of Southern Patio with capital expenditures decreasing $7,279 from the comparable prior year period. Griffon expects capital spending to be in the range of $65,000 to $70,000 for 2012.

During the nine months ended June 30, 2012, cash used in financing activities totaled $20,255 compared to cash provided by financing activities of $123,843 in the prior year. In each of the first three quarters of 2012, the Board of Directors approved a quarterly cash dividends of $0.02 per common share each, which were paid on December 27, 2011, March 27, 2012 and June 26, 2012, to holders of common stock as of the close of business on November 29, 2011, February 28, 2012 and May 29, 2012, respectively. In 2011, Griffon issued $145,754 of debt, net of payments, which included issuing $550,000 of 7.125% Senior Notes due 2018 and repaying $430,000 of existing loans.

On August 2, 2012, the Board of Directors declared a fourth quarterly cash dividend of $0.02 per share, payable on September 25, 2012 to shareholders of record as of the close of business on August 28, 2012.

Payments related to Telephonics revenue are received in accordance with the terms of development and production subcontracts; certain of such receipts are progress or performance based payments. Plastics customers are generally substantial industrial companies whose payments have been steady, reliable and made in accordance with the terms governing such sales. Plastics sales satisfy orders that are received in advance of production, typically with payment terms established in advance. With respect to HBP, there have been no material adverse impacts on payment for sales.

A small number of customers account for, and are expected to continue to account for, a substantial portion of Griffon’s consolidated revenue. For the nine months ended June 30, 2012:

• The United States Government and its agencies, through either prime or subcontractor relationships, represented 18% of Griffon’s consolidated revenue and 80% of Telephonics’ revenue.

• Procter & Gamble represented 13% of Griffon’s consolidated revenue and 44% of Plastics’ revenue.

• The Home Depot represented 12% of Griffon’s consolidated revenue and 25% of Home & Building Products’ revenue.

35

No other customers exceeded 9% of consolidated revenue. Future operating results will continue to substantially depend on the success of Griffon’s largest customers and Griffon’s relationships with them. Orders from these customers are subject to fluctuation and may be reduced materially. The loss of all or a portion of volume from any one of these customers could have a material adverse impact on Griffon’s liquidity and operations.

On March 17, 2011, in an unregistered offering through a private placement under Rule 144A, Griffon issued, at par, $550,000 of 7.125% Senior Notes due in 2018; interest is payable semi-annually. On August 9, 2011, Griffon exchanged all of the Senior Notes for substantially identical Senior Notes registered under the Securities Act of 1933 (“Senior Notes”), via an exchange offer.

The Senior Notes can be redeemed prior to April 1, 2014 at a price of 100% of principal plus a make-whole premium and accrued interest; on or after April 1, 2014, the Senior Notes can be redeemed at a certain price (declining from 105.344% of principal on or after April 1, 2014 to 100% of principal on or after April 1, 2017), plus accrued interest. Proceeds from the Senior Notes were used to pay down the outstanding borrowings under a senior secured term loan facility and two senior secured revolving credit facilities of certain of the Company’s subsidiaries. The Senior Notes are senior unsecured obligations of Griffon guaranteed by certain domestic subsidiaries, and are subject to certain covenants, limitations and restrictions.

On March 18, 2011, Griffon entered into a five-year $200,000 Revolving Credit Facility (“Credit Agreement”), which includes a letter of credit sub-facility with a limit of $50,000, a multi-currency sub-facility of $50,000 and a swingline sub-facility with a limit of $30,000. Borrowings under the Credit Agreement may be repaid and re-borrowed at any time, subject to final maturity of the facility or the occurrence of a default or event of default under the Credit Agreement. Interest is payable on borrowings at either a LIBOR or base rate benchmark rate plus an applicable margin, which will adjust based on financial performance. The margins are 1.75% for base rate loans and 2.75% for LIBOR loans, in each case without a floor. The Credit Agreement has certain financial maintenance tests including a maximum total leverage ratio, a maximum senior secured leverage ratio and a minimum interest coverage ratio as well as customary affirmative and negative covenants and events of default. The Credit Agreement also includes certain restrictions, such as limitations on the incurrence of indebtedness and liens and the making of restricted payments and investments. Borrowings under the Credit Agreement are guaranteed by certain domestic subsidiaries and are secured, on a first priority basis, by substantially all assets of the Company and the guarantors.

At June 30, 2012, there were $21,516 of standby letters of credit outstanding under the Credit Agreement; $178,484 was available for borrowing at that date.

On December 21, 2009, Griffon issued $100,000 principal of 4% convertible subordinated notes due 2017 (the “2017 Notes”). The initial conversion rate of the 2017 Notes was 67.0799 shares of Griffon’s common stock per $1,000 principal amount of notes, corresponding to an initial conversion price of $14.91 per share, a 23% conversion premium over the $12.12 closing price on December 15, 2009. When a cash dividend is declared that would result in an adjustment to the conversion ratio of less than 1%, any adjustment to the conversion ratio is deferred until the first to occur of (i) actual conversion, (ii) the 42nd trading day prior to maturity of the notes, and (iii) such time as the cumulative adjustment equals or exceeds 1%. As of September 25, 2012, aggregate dividends of $0.08 per share would result in a cumulative change in the conversion rate of approximately 0.9%. Griffon used 8.75% as the nonconvertible debt-borrowing rate to discount the 2017 Notes and will amortize the debt discount through January 2017. At issuance, the debt component of the 2017 Notes was $75,437 and debt discount was $24,563. At June 30, 2012 and September 30, 2011, the 2017 Notes had a capital in excess of par component, net of tax, of $15,720.

36

On December 20, 2010, Griffon entered into two second lien real estate mortgages to secure new loans totaling $11,834. The loans mature in February 2016, are collateralized by the related properties and are guaranteed by Griffon. The loans bear interest at a rate of LIBOR plus 3% with the option to swap to a fixed rate.

Griffon has other real estate mortgages, collateralized by real property, which bear interest at 6.3% and mature in 2016. On October 3, 2011, the mortgage at Russia, Ohio was paid in full, on maturity.

Griffon’s Employee Stock Ownership Plan (“ESOP”) entered into a loan agreement in August 2010 to borrow $20,000 over a one-year period. The proceeds were used to purchase 1,874,737 shares of Griffon common stock in the open market for $19,973. The loan bears interest at a) LIBOR plus 2.5% or b) the lender’s prime rate, at Griffon’s option. In November 2011, Griffon exercised an option to convert the outstanding loan to a five-year term loan; principal is payable in quarterly installments of $250, beginning December 2011, with a balloon payment of $15,223 due at maturity (November 2016). The loan is secured by shares purchased with the proceeds of the loan, and repayment is guaranteed by Griffon. At June 30, 2012, $19,223 was outstanding.

In addition, the ESOP has a loan agreement, guaranteed by Griffon, which requires quarterly principal payments of $156 and interest through the extended expiration date of December 2013 at which time the $3,125 balance of the loan, and any outstanding interest, will be payable. The primary purpose of this loan was to purchase 547,605 shares of Griffon’s common stock in October 2008. The loan is secured by shares purchased with the proceeds of the loan, and repayment is guaranteed by Griffon. The loan bears interest at rates based upon the prime rate or LIBOR. At June 30, 2012, $3,906 was outstanding.

In October 2006, CBP entered into a capital lease totaling $14,290 for real estate in Troy, Ohio. The lease matures in 2021, bears interest at a fixed rate of 5.1%, is secured by a mortgage on the real estate and is guaranteed by Griffon.

At June 30, 2012 and September 30, 2011, Griffon had $532 of 4% convertible subordinated notes due 2023 (the “2023 Notes”) outstanding. Holders of the 2023 Notes may require Griffon to repurchase all or a portion of their 2023 Notes on July 18, 2013 and 2018, if Griffon’s common stock price is below the conversion price of the 2023 Notes, as well as upon a change in control. An adjustment to the conversion rate will be required as the result of payment of a cash dividend only if such adjustment would be greater than 1% (or at such time as the cumulative impact on the conversion rate reaches 1% in the aggregate). As of September 25, 2012, aggregate dividends of $0.08 per share would result in a cumulative change in the conversion rate of approximately 0.9%. At June 30, 2012 and September 30, 2011, the 2023 Notes had no capital in excess of par value component as substantially all of these notes were put to Griffon at par and settled in July 2010.

In November 2010, Clopay Europe GMBH (“Clopay Europe”) entered into a €10,000 revolving credit facility and a €20,000 term loan. The facility accrues interest at Euribor plus 2.1% per annum, and the term loan accrues interest at Euribor plus 2.2% per annum. The revolving facility matures in November 2012, but is renewable upon mutual agreement with the bank. In July 2011, the full €20,000 was drawn on the Term Loan, with a portion of the proceeds used to repay borrowings under the revolving credit facility. The term loan is payable in ten equal quarterly installments which began in September 2011, with maturity in December 2013. Under the term loan, Clopay Europe is required to maintain a certain minimum equity to assets ratio and keep leverage below a certain level, defined as the ratio of total debt to EBITDA. At June 30, 2012, there was €1,000 borrowed on the revolving credit with €9,000 available for borrowing.

In February 2012, Clopay do Brazil, a subsidiary of Plastics, borrowed $4,000 at a rate of 104.5% of Brazilian CDI. The loan was used to refinance existing loans and is collateralized by accounts receivable and a 50% guaranty by Plastics and is to be repaid in four equal, semi-annual installments of principal plus interest, starting August 2012. Clopay do Brazil also maintains a line of credit of approximately $1,700. Interest on borrowings accrue at a rate of Brazilian CDI plus 6.0%. At June 30, 2012 there was approximately $1,346 borrowed under the line.

37

In connection with the ATT acquisition, Clopay Ames True Temper Holding Corp. (“Clopay Ames”), a subsidiary of Griffon, entered into a $375,000 secured term Loan (“Term Loan”) and a $125,000 asset based lending agreement (“ABL”).

On November 30, 2010, Clopay Ames, as required under the Term Loan agreement, entered into an interest rate swap on a notional amount of $200,000 of the Term Loan. The agreement fixed the LIBOR component of the Term Loan interest rate at 2.085% for the notional amount of the swap.

At June 30, 2012, Griffon and its subsidiaries were in compliance with the terms and covenants of its credit and loan agreements.

In August 2011, Griffon’s Board of Directors authorized the repurchase of up to $50,000 of Griffon’s outstanding common stock. Under this repurchase program, the Company may, from time to time, purchase shares of its common stock, depending upon market conditions, in open market or privately negotiated transactions, including pursuant to a 10b5-1 plan. In the first quarter of 2012, Griffon purchased 283,400 shares of common stock, for a total of $2,351, or $8.29 per share. In the third quarter of 2012, Griffon purchased 417,667 shares of common stock, for a total of $3,320, or $7.95 per share; in total, Griffon has purchased 866,446 shares of common stock, for a total of $6,980, or $8.06 per share, under this repurchase program. $43,020 remains under the $50,000 authorization. Subsequent to June 30, 2012, Griffon purchased 66,199 shares of common stock, for a total of $560, or $8.47 per share.

Griffon substantially concluded its remaining disposal activities for the Installation Services business, discontinued in 2008, in the second quarter of 2009 and does not expect to incur significant expense in the future. Future net cash outflows to satisfy liabilities related to disposal activities accrued at June 30, 2012 are estimated to be $3,077. Certain of Griffon’s subsidiaries are also contingently liable for approximately $512 related to certain facility leases with varying terms through 2012 that were assigned to the respective purchasers of certain of the Installation Services businesses. Griffon does not believe it has a material exposure related to these contingencies.

During the nine months ended June 30, 2012 and 2011, Griffon used cash for discontinued operations of $1,690 and $829, respectively, related to settling remaining Installation Services liabilities.

CRITICAL ACCOUNTING POLICIES

The preparation of Griffon’s consolidated financial statements in conformity with GAAP requires Griffon to make estimates and judgments that affect reported amounts of assets, liabilities, sales and expenses, and the related disclosures of contingent assets and contingent liabilities at the date of the financial statements. Griffon evaluates these estimates and judgments on an ongoing basis and base the estimates on historical experience, current conditions and various other assumptions that are believed to be reasonable under the circumstances. The results of these estimates form the basis for making judgments about the carrying values of assets and liabilities, as well as identifying and assessing the accounting treatment with respect to commitments and contingencies. Griffon’s actual results may materially differ from these estimates. There have been no changes in Griffon’s critical accounting policies from September 30, 2011.

Griffon’s significant accounting policies and procedures are explained in the Management Discussion and Analysis section in the Annual Report on Form 10-K for the year ended September 30, 2011. In the selection of the critical accounting policies, the objective is to properly reflect the financial position and results of operations for each reporting period in a consistent manner that can be understood by the reader of the financial statements. Griffon considers an estimate to be critical if it is subjective and if changes in the estimate using different assumptions would result in a material impact on the financial position or results of operations of Griffon.

RECENT ACCOUNTING PRONOUNCEMENTS

The Financial Accounting Standards Board issues, from time to time, new financial accounting standards, staff positions and emerging issues task force consensus. See the Notes to Condensed Consolidated Financial Statements for a discussion of these matters.

This Quarterly Report on Form 10-Q contains forward-looking statements. All statements other than statements of historical fact, including, without limitation, statements regarding Griffon’s financial position, business strategy and the plans and objectives of Griffon’s management for future operations, are forward-looking statements. Without limiting the generality of the foregoing, in some cases you can identify forward-looking statements by terminology such as “may,” “will,” “should,” “would,” “could,” “anticipate,” “believe,” “estimate,” “expect,” “plan,” “intend” or the negative of these expressions or comparable terminology. Such forward-looking statements involve important risks and uncertainties that could significantly affect anticipated results in the future and, accordingly, such results may differ materially from those expressed in any forward-looking statements. These risks and uncertainties include, among others: general domestic and international business, financial market and economic conditions; the credit market; the housing market; the results of Griffon’s restructuring and disposal efforts; competitive factors; pricing pressures for resin and steel; capacity and supply constraints; weather patterns; Griffon’s ability to identify and successfully consummate and integrate value-adding acquisition opportunities; the ability of Griffon to remain in compliance with the covenants under its respective credit facilities; and the inherent uncertainties relating to resolution of ongoing legal and environmental matters from time to time. Additional important factors that could cause the statements made in this Quarterly Report on Form 10-Q or the actual results of operations or financial condition of Griffon to differ are discussed under the caption “Item 1A. Risk Factors” and “Special Notes Regarding Forward-Looking Statements” in Griffon’s Annual Report on Form 10-K for the year ended September 30, 2011. Some of the factors are also discussed elsewhere in this Quarterly Report on Form 10-Q and have been or may be discussed from time to time in Griffon’s filings with the U.S. Securities and Exchange Commission. Readers are cautioned not to place undue reliance on Griffon’s forward-looking statements. Griffon does not undertake any obligation to release publicly any revisions to these forward-looking statements to reflect future events or circumstances or to reflect the occurrence of unanticipated events.

Item 3 - Quantitative and Qualitative Disclosure About Market Risk

Interest Rates

Griffon’s exposure to market risk for changes in interest rates relates primarily to variable interest rate debt and investments in cash and cash equivalents.

Certain of Griffon’s credit facilities have Libor, Euribor and Brazilian CDI-based variable interest rates. Due to the current and expected level of borrowings under these facilities, a 100 basis point change in Libor would not have a material impact on Griffon’s results of operations or liquidity.

Foreign Exchange

Griffon conducts business in various non-U.S. countries, primarily in Canada, Mexico, Europe, Brazil, Australia and China; therefore, changes in the value of the currencies of these countries affect the financial position and cash flows when translated into U.S. Dollars. Griffon has generally accepted the exposure to exchange rate movements relative to its non-U.S. operations. Griffon may, from time to time, hedge its currency risk exposures. A change of 5% or less in the value of all applicable foreign currencies would not have a material effect on Griffon’s financial position and cash flows.

Item 4 - Controls and Procedures

Under the supervision and with the participation of Griffon’s Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), Griffon’s disclosure controls and procedures, as defined by Exchange Act Rule 13a-15(e) and 15d-15(e), were evaluated as of the end of the period covered by this report. Based on that evaluation, Griffon’s CEO and CFO concluded that Griffon’s disclosure controls and procedures were effective at the reasonable assurance level.

During the period covered by this report, there were no changes in Griffon’s internal control over financial reporting which materially affected, or are reasonably likely to materially affect, Griffon’s internal control over financial reporting.

39

Limitations on the Effectiveness of Controls

Griffon believes that a control system, no matter how well designed and operated, cannot provide absolute assurance that the objectives of the control system are met, and no evaluation of controls can provide absolute assurance that all controls issues and instances of fraud, if any, within a company have been detected. Griffon’s disclosure controls and procedures, as defined by Exchange Act Rule 13a-15(e) and 15d-15(e), are designed to provide reasonable assurance of achieving their objectives.

PART II - OTHER INFORMATION

Item 1	Legal Proceedings
	None
Item 1A	Risk Factors
	In addition to the other information set forth in this report, carefully consider the factors discussed in Item 1A to Part I in Griffon’s Annual Report on Form 10-K for the year ended September 30, 2011, which could materially affect Griffon’s business, financial condition or future results. The risks described in Griffon’s Annual Report on Form 10-K are not the only risks facing Griffon. Additional risks and uncertainties not currently known to Griffon or that Griffon currently deems to be immaterial also may materially adversely affect Griffon’s business, financial condition and/or operating results.

Legal Matters and Contingencies [Text Block]

NOTE 19 — COMMITMENTS AND CONTINGENCIES

Legal and environmental
Department of Environmental Conservation of New York State (“DEC”), with ISC Properties, Inc. Lightron Corporation (“Lightron”), a wholly-owned subsidiary of Griffon, once conducted operations at a location in Peekskill in the Town of Cortlandt, New York (the “Peekskill Site”) owned by ISC Properties, Inc. (“ISC”), a wholly-owned subsidiary of Griffon. ISC sold the Peekskill Site in November 1982.

Subsequently, Griffon was advised by the DEC that random sampling at the Peekskill Site and in a creek near the Peekskill Site indicated concentrations of solvents and other chemicals common to Lightron’s prior plating operations. ISC then entered into a consent order with the DEC in 1996 (the “Consent Order”) to perform a remedial investigation and prepare a feasibility study. After completing the initial remedial investigation pursuant to the Consent Order, ISC was required by the DEC, and did conduct accordingly over the next several years, supplemental remedial investigations, including soil vapor investigations, under the Consent Order.

In April 2009, the DEC advised ISC’s representatives that both the DEC and the New York State Department of Health had reviewed and accepted an August 2007 Remedial Investigation Report and an Additional Data Collection Summary Report dated January 30, 2009. With the acceptance of these reports, ISC completed the remedial investigation required under the Consent Order and was authorized, accordingly, by the DEC to conduct the Feasibility Study required by the Consent Order. Pursuant to the requirements of the Consent Order and its obligations thereunder, ISC, without acknowledging any responsibility to perform any remediation at the Site, submitted to the DEC in August 2009, a draft feasibility study which recommended for the soil, groundwater and sediment medias, remediation alternatives having a current net capital cost value, in the aggregate, of approximately $5,000. In February 2011, DEC advised ISC it has accepted and approved the feasibility study. Accordingly, ISC has no further obligations under the consent order.

Upon acceptance of the feasibility study, DEC issued a Proposed Remedial Action Plan (“PRAP”) that sets forth the proposed remedy for the site. The PRAP accepted the recommendation contained in the feasibility study for remediation of the soil and groundwater medias, but selected a different remediation alternative for the sediment medium. The approximate cost and the current net capital cost value of the remedy proposed by DEC in the PRAP is approximately $10,000. After receiving public comments on the PRAP, the DEC issued a Record of Decision (“ROD”) that set forth the specific remedies selected and responded to public comments. The remedies selected by the DEC in the ROD are the same remedies as those set forth in the PRAP.

It is now expected that DEC will enter into negotiations with potentially responsible parties to request they undertake performance of the remedies selected in the ROD, and if such parties do not agree to implement such remedies, then the State may use State Superfund money to remediate the Peekskill site and seek recovery of costs from such parties. Griffon does not acknowledge any responsibility to perform any remediation at the Peekskill Site.

Improper Advertisement Claim involving UnionTools Products. Since December 2004, a customer of ATT has been named in various litigation matters relating to certain UnionTools products. The plaintiffs in those litigation matters have asserted causes of action against the customer of ATT for improper advertisement to end consumers. The allegations suggest that advertisements led the consumers to believe that Union Tools’ hand tools were wholly manufactured within boundaries of the United States. The complaints assert various causes of action against the customer of ATT under federal and state law, including common law fraud. At some point, likely once the litigation against the customer of ATT ends, the customer may seek indemnity (including recovery of its legal fees and costs) against ATT for an unspecified amount. Presently, ATT cannot estimate the amount of loss, if any, if the customer were to seek legal recourse against ATT.

Department of Environmental Conservation of New York State, regarding Frankfort, NY site. During fiscal 2009, an underground fuel tank with surrounding soil contamination was discovered at the Frankfort, N.Y. site which is the result of historical facility operations prior to ATT’s ownership. While ATT was actively working with the DEC and the New York State Department of Health to define remediation requirements relative to the underground fuel tank, the DEC took the position that ATT was responsible to remediate other types of contamination on the site. After negotiations with the DEC, on August 15, 2011, ATT executed an Order on Consent with the DEC. The Order is without admission or finding of liability or acknowledgement that there has been a release of hazardous substances at the site. Importantly, the Order does not waive any rights that ATT has under a 1991 Consent Judgment entered into between the DEC and a predecessor of ATT relating to the site. The Order requires that ATT identify Areas of Concern at the site, and formulate a strategy to investigate and remedy both on and off site conditions in compliance with applicable environmental law. At the conclusion of the remedy phase of the remediation to the satisfaction of the DEC, the DEC will issue a Certificate of Completion. On September 26, 2011 ATT submitted a Records Search Report to DEC and on October 24, 2011 filed the draft Remedial Investigation Work Plan (“RIWP”) completing the first two steps under the Order. DEC responded to ATT’s draft work plan and requested that ATT submit an amended work plan reflecting certain changes. On June 1, 2012, ATT submitted to DEC a revised RIWP and Proposed Interim Remedial Measure Work Plan (“IRM”) for the demolition of various buildings at the site. DEC is currently reviewing both submissions.

U.S. Government investigations and claims

Defense contracts and subcontracts, including Griffon’s contracts and subcontracts, are subject to audit and review by various agencies and instrumentalities of the United States government, including, among others, the Defense Contract Audit Agency (“DCAA”) and the Department of Justice, which has responsibility for asserting claims on behalf of the U.S. government. In addition to ongoing audits, pursuant to an administrative subpoena Griffon is currently providing information to the U.S. Department of Defense Office of the Inspector General. No claim has been asserted against Griffon, and Griffon is unaware of any material financial exposure in connection with the Inspector General’s inquiry.

In general, departments and agencies of the U.S. Government have the authority to investigate various transactions and operations of Griffon, and the results of such investigations may lead to administrative, civil or criminal proceedings, the ultimate outcome of which could be fines, penalties, repayments or compensatory or treble damages. U.S. Government regulations provide that certain findings against a contractor may lead to suspension or debarment from future U.S. Government contracts or the loss of export privileges for a company or an operating division or subdivision. Suspension or debarment could have material adverse effect on Telephonics because of its reliance on government contracts.

General legal

Griffon is a party to legal proceedings arising in the ordinary course of business and is subject to various laws and regulations relating to the protection of the environment. Management believes, based on facts presently known to it, that the resolution of the matters above and such other matters will not have a material adverse effect on Griffon’s consolidated financial position, results of operations or cash flows.

[1] On March 17, 2011, in an unregistered offering through a private placement under Rule 144A, Griffon issued, at par, $550,000 of 7.125% Senior Notes due in 2018; interest is payable semi-annually. On August 9, 2011, Griffon exchanged all of the Senior Notes for substantially identical Senior Notes registered under the Securities Act of 1933 ("Senior Notes"), via an exchange offer.The Senior Notes can be redeemed prior to April 1, 2014 at a price of 100% of principal plus a make-whole premium and accrued interest; on or after April 1, 2014, the Senior Notes can be redeemed at a certain price (declining from 105.344% of principal on or after April 1, 2014 to 100% of principal on or after April 1, 2017), plus accrued interest. Proceeds from the Senior Notes were used to pay down the outstanding borrowings under a senior secured term loan facility and two senior secured revolving credit facilities of certain of the Company's subsidiaries. The Senior Notes are senior unsecured obligations of Griffon guaranteed by certain domestic subsidiaries, and are subject to certain covenants, limitations and restrictions.On March 18, 2011, Griffon entered into a five-year $200,000 Revolving Credit Facility ("Credit Agreement"), which includes a letter of credit sub-facility with a limit of $50,000, a multi-currency sub-facility of $50,000 and a swingline sub-facility with a limit of $30,000. Borrowings under the Credit Agreement may be repaid and re-borrowed at any time, subject to final maturity of the facility or the occurrence of a default or event of default under the Credit Agreement. Interest is payable on borrowings at either a LIBOR or base rate benchmark rate plus an applicable margin, which will adjust based on financial performance. The margins are 1.75% for base rate loans and 2.75% for LIBOR loans, in each case without a floor. The Credit Agreement has certain financial maintenance tests including a maximum total leverage ratio, a maximum senior secured leverage ratio and a minimum interest coverage ratio as well as customary affirmative and negative covenants and events of default. The Credit Agreement also includes certain restrictions, such as limitations on the incurrence of indebtedness and liens and the making of restricted payments and investments. Borrowings under the Credit Agreement are guaranteed by certain domestic subsidiaries and are secured, on a first priority basis, by substantially all assets of the Company and the guarantors.At June 30, 2012, there were $21,516 of standby letters of credit outstanding under the Credit Agreement; $178,484 was available for borrowing at that date.

[2] On December 21, 2009, Griffon issued $100,000 principal of 4% convertible subordinated notes due 2017 (the "2017 Notes"). The initial conversion rate of the 2017 Notes was 67.0799 shares of Griffon's common stock per $1,000 principal amount of notes, corresponding to an initial conversion price of $14.91 per share, a 23% conversion premium over the $12.12 closing price on December 15, 2009. When a cash dividend is declared that would result in an adjustment to the conversion ratio of less than 1%, any adjustment to the conversion ratio is deferred until the first to occur of (i) actual conversion, (ii) the 42nd trading day prior to maturity of the notes, and (iii) such time as the cumulative adjustment equals or exceeds 1%. As of September 25, 2012, aggregate dividends of $0.08 per share would result in a cumulative change in the conversion rate of approximately 0.9%. Griffon used 8.75% as the nonconvertible debt-borrowing rate to discount the 2017 Notes and will amortize the debt discount through January 2017. At issuance, the debt component of the 2017 Notes was $75,437 and debt discount was $24,563. At June 30, 2012 and September 30, 2011, the 2017 Notes had a capital in excess of par component, net of tax, of $15,720.

[3] On December 20, 2010, Griffon entered into two second lien real estate mortgages to secure new loans totaling $11,834. The loans mature in February 2016, are collateralized by the related properties and are guaranteed by Griffon. The loans bear interest at a rate of LIBOR plus 3% with the option to swap to a fixed rate.Griffon has other real estate mortgages, collateralized by real property, which bear interest at 6.3% and mature in 2016. On October 3, 2011, the mortgage at Russia, Ohio was paid in full, on maturity.

[4] Griffon's Employee Stock Ownership Plan ("ESOP") entered into a loan agreement in August 2010 to borrow $20,000 over a one-year period. The proceeds were used to purchase 1,874,737 shares of Griffon common stock in the open market for $19,973. The loan bears interest at a) LIBOR plus 2.5% or b) the lender's prime rate, at Griffon's option. In November 2011, Griffon exercised an option to convert the outstanding loan to a five-year term loan; principal is payable in quarterly installments of $250, beginning December 2011, with a balloon payment of $15,223 due at maturity (November 2016). The loan is secured by shares purchased with the proceeds of the loan, and repayment is guaranteed by Griffon. At June 30, 2012, $19,223 was outstanding.In addition, the ESOP has a loan agreement, guaranteed by Griffon, which requires quarterly principal payments of $156 and interest through the extended expiration date of December 2013 at which time the $3,125 balance of the loan, and any outstanding interest, will be payable. The primary purpose of this loan was to purchase 547,605 shares of Griffon's common stock in October 2008. The loan is secured by shares purchased with the proceeds of the loan, and repayment is guaranteed by Griffon. The loan bears interest at rates based upon the prime rate or LIBOR. At June 30, 2012, $3,906 was outstanding.

[5] In October 2006, CBP entered into a capital lease totaling $14,290 for real estate in Troy, Ohio. The lease matures in 2021, bears interest at a fixed rate of 5.1%, is secured by a mortgage on the real estate and is guaranteed by Griffon.

[6] At June 30, 2012 and September 30, 2011, Griffon had $532 of 4% convertible subordinated notes due 2023 (the "2023 Notes") outstanding. Holders of the 2023 Notes may require Griffon to repurchase all or a portion of their 2023 Notes on July 18, 2013 and 2018, if Griffon's common stock price is below the conversion price of the 2023 Notes, as well as upon a change in control. An adjustment to the conversion rate will be required as the result of payment of a cash dividend only if such adjustment would be greater than 1% (or at such time as the cumulative impact on the conversion rate reaches 1% in the aggregate). As of September 25, 2012, aggregate dividends of $0.08 per share would result in a cumulative change in the conversion rate of approximately 0.9%. At June 30, 2012 and September 30, 2011, the 2023 Notes had no capital in excess of par value component as substantially all of these notes were put to Griffon at par and settled in July 2010.

[7] In November 2010, Clopay Europe GMBH ("Clopay Europe") entered into a €10,000 revolving credit facility and a €20,000 term loan. The facility accrues interest at Euribor plus 2.1% per annum, and the term loan accrues interest at Euribor plus 2.2% per annum. The revolving facility matures in November 2012, but is renewable upon mutual agreement with the bank. In July 2011, the full €20,000 was drawn on the Term Loan, with a portion of the proceeds used to repay borrowings under the revolving credit facility. The term loan is payable in ten equal quarterly installments which began in September 2011, with maturity in December 2013. Under the term loan, Clopay Europe is required to maintain a certain minimum equity to assets ratio and keep leverage below a certain level, defined as the ratio of total debt to EBITDA. At June 30, 2012, there was € 1,000 borrowed on the revolving credit with € 9,000 available for borrowing.

[8] In February 2012, Clopay do Brazil, a subsidiary of Plastics, borrowed $4,000 at a rate of 104.5% of Brazilian CDI. The loan was used to refinance existing loans and is collateralized by accounts receivable and a 50% guaranty by Plastics and is to be repaid in four equal, semi-annual installments of principal plus accrued interest beginning in August 2012. Clopay do Brazil also maintains a line of credit of approximately $1,700. Interest on borrowings accrue at a rate of Brazilian CDI plus 6.0%. At June 30, 2012 there was approximately $1,346 borrowed under the line.

FAIR VALUE MEASUREMENTS

9 Months Ended

Jun. 30, 2012

Fair Value Disclosures [Text Block]

NOTE 2 – FAIR VALUE MEASUREMENTS

The carrying values of cash and equivalents, accounts receivable, accounts and notes payable and revolving credit debt approximate fair value due to either the short-term nature of such instruments or the fact that the interest rate of the revolving credit debt is based upon current market rates.

The fair values of Griffon’s 2018 senior notes, and 2017 and 2023 4% convertible notes approximated $556,000, $91,000 and $532, respectively, on June 30, 2012. Fair values were based upon quoted market prices (level 1 inputs).

Insurance contracts with a value of $4,213 and trading securities with a value of $290 at June 30, 2012 are measured and recorded at fair value based upon quoted prices in active markets for identical assets (level 1 inputs).

Items Measured at Fair Value on a Recurring Basis

At June 30, 2012, Griffon had $1,250 of Australian dollar contracts at a weighted average rate of $0.97. The contracts, which protect Australia operations from currency fluctuations for U.S. dollar based purchases, do not qualify for hedge accounting. A fair value gain of $15 and $55 was recorded in other assets and to other income for the outstanding contracts, based on similar contract values (level 2 inputs), for the three and nine months ended June 30, 2012, respectively. The contracts expire in 30 to 90 days.

[1] On March 17, 2011, in an unregistered offering through a private placement under Rule 144A, Griffon issued, at par, $550,000 of 7.125% Senior Notes due in 2018; interest is payable semi-annually. On August 9, 2011, Griffon exchanged all of the Senior Notes for substantially identical Senior Notes registered under the Securities Act of 1933 ("Senior Notes"), via an exchange offer.The Senior Notes can be redeemed prior to April 1, 2014 at a price of 100% of principal plus a make-whole premium and accrued interest; on or after April 1, 2014, the Senior Notes can be redeemed at a certain price (declining from 105.344% of principal on or after April 1, 2014 to 100% of principal on or after April 1, 2017), plus accrued interest. Proceeds from the Senior Notes were used to pay down the outstanding borrowings under a senior secured term loan facility and two senior secured revolving credit facilities of certain of the Company's subsidiaries. The Senior Notes are senior unsecured obligations of Griffon guaranteed by certain domestic subsidiaries, and are subject to certain covenants, limitations and restrictions.On March 18, 2011, Griffon entered into a five-year $200,000 Revolving Credit Facility ("Credit Agreement"), which includes a letter of credit sub-facility with a limit of $50,000, a multi-currency sub-facility of $50,000 and a swingline sub-facility with a limit of $30,000. Borrowings under the Credit Agreement may be repaid and re-borrowed at any time, subject to final maturity of the facility or the occurrence of a default or event of default under the Credit Agreement. Interest is payable on borrowings at either a LIBOR or base rate benchmark rate plus an applicable margin, which will adjust based on financial performance. The margins are 1.75% for base rate loans and 2.75% for LIBOR loans, in each case without a floor. The Credit Agreement has certain financial maintenance tests including a maximum total leverage ratio, a maximum senior secured leverage ratio and a minimum interest coverage ratio as well as customary affirmative and negative covenants and events of default. The Credit Agreement also includes certain restrictions, such as limitations on the incurrence of indebtedness and liens and the making of restricted payments and investments. Borrowings under the Credit Agreement are guaranteed by certain domestic subsidiaries and are secured, on a first priority basis, by substantially all assets of the Company and the guarantors. At June 30, 2012, there were $21,516 of standby letters of credit outstanding under the Credit Agreement; $178,484 was available for borrowing at that date.

[2] On December 21, 2009, Griffon issued $100,000 principal of 4% convertible subordinated notes due 2017 (the "2017 Notes"). The initial conversion rate of the 2017 Notes was 67.0799 shares of Griffon's common stock per $1,000 principal amount of notes, corresponding to an initial conversion price of $14.91 per share, a 23% conversion premium over the $12.12 closing price on December 15, 2009. When a cash dividend is declared that would result in an adjustment to the conversion ratio of less than 1%, any adjustment to the conversion ratio is deferred until the first to occur of (i) actual conversion, (ii) the 42nd trading day prior to maturity of the notes, and (iii) such time as the cumulative adjustment equals or exceeds 1%. As of September 25, 2012, aggregate dividends of $0.08 per share would result in a cumulative change in the conversion rate of approximately 0.9%. Griffon used 8.75% as the nonconvertible debt-borrowing rate to discount the 2017 Notes and will amortize the debt discount through January 2017. At issuance, the debt component of the 2017 Notes was $75,437 and debt discount was $24,563. At June 30, 2012 and September 30, 2011, the 2017 Notes had a capital in excess of par component, net of tax, of $15,720.

[3] On December 20, 2010, Griffon entered into two second lien real estate mortgages to secure new loans totaling $11,834. The loans mature in February 2016, are collateralized by the related properties and are guaranteed by Griffon. The loans bear interest at a rate of LIBOR plus 3% with the option to swap to a fixed rate.Griffon has other real estate mortgages, collateralized by real property, which bear interest at 6.3% and mature in 2016. On October 3, 2011, the mortgage at Russia, Ohio was paid in full, on maturity.

[4] Griffon's Employee Stock Ownership Plan ("ESOP") entered into a loan agreement in August 2010 to borrow $20,000 over a one-year period. The proceeds were used to purchase 1,874,737 shares of Griffon common stock in the open market for $19,973. The loan bears interest at a) LIBOR plus 2.5% or b) the lender's prime rate, at Griffon's option. In November 2011, Griffon exercised an option to convert the outstanding loan to a five-year term loan; principal is payable in quarterly installments of $250, beginning December 2011, with a balloon payment of $15,223 due at maturity (November 2016). The loan is secured by shares purchased with the proceeds of the loan, and repayment is guaranteed by Griffon. At June 30, 2012, $19,223 was outstanding.In addition, the ESOP has a loan agreement, guaranteed by Griffon, which requires quarterly principal payments of $156 and interest through the extended expiration date of December 2013 at which time the $3,125 balance of the loan, and any outstanding interest, will be payable. The primary purpose of this loan was to purchase 547,605 shares of Griffon's common stock in October 2008. The loan is secured by shares purchased with the proceeds of the loan, and repayment is guaranteed by Griffon. The loan bears interest at rates based upon the prime rate or LIBOR. At June 30, 2012, $3,906 was outstanding.

[5] In October 2006, CBP entered into a capital lease totaling $14,290 for real estate in Troy, Ohio. The lease matures in 2021, bears interest at a fixed rate of 5.1%, is secured by a mortgage on the real estate and is guaranteed by Griffon.

[6] At June 30, 2012 and September 30, 2011, Griffon had $532 of 4% convertible subordinated notes due 2023 (the "2023 Notes") outstanding. Holders of the 2023 Notes may require Griffon to repurchase all or a portion of their 2023 Notes on July 18, 2013 and 2018, if Griffon's common stock price is below the conversion price of the 2023 Notes, as well as upon a change in control. An adjustment to the conversion rate will be required as the result of payment of a cash dividend only if such adjustment would be greater than 1% (or at such time as the cumulative impact on the conversion rate reaches 1% in the aggregate). As of September 25, 2012, aggregate dividends of $0.08 per share would result in a cumulative change in the conversion rate of approximately 0.9%. At June 30, 2012 and September 30, 2011, the 2023 Notes had no capital in excess of par value component as substantially all of these notes were put to Griffon at par and settled in July 2010.

[7] In November 2010, Clopay Europe GMBH ("Clopay Europe") entered into a €10,000 revolving credit facility and a €20,000 term loan. The facility accrues interest at Euribor plus 2.1% per annum, and the term loan accrues interest at Euribor plus 2.2% per annum. The revolving facility matures in November 2012, but is renewable upon mutual agreement with the bank. In July 2011, the full €20,000 was drawn on the Term Loan, with a portion of the proceeds used to repay borrowings under the revolving credit facility. The term loan is payable in ten equal quarterly installments which began in September 2011, with maturity in December 2013. Under the term loan, Clopay Europe is required to maintain a certain minimum equity to assets ratio and keep leverage below a certain level, defined as the ratio of total debt to EBITDA. At June 30, 2012, there was €1,000 borrowed on the revolving credit with €9,000 available for borrowing.

[8] In February 2012, Clopay do Brazil, a subsidiary of Plastics, borrowed $4,000 at a rate of 104.5% of Brazilian CDI. The loan was used to refinance existing loans and is collateralized by accounts receivable and a 50% guaranty by Plastics and is to be repaid in four equal, semi-annual installments of principal plus accrued interest beginning in August 2012. Clopay do Brazil also maintains a line of credit of approximately $1,700. Interest on borrowings accrue at a rate of Brazilian CDI plus 6.0%. At June 30, 2012 there was approximately $1,346 borrowed under the line.

[9] Includes capital leases.

[10] In connection with the ATT acquisition, Clopay Ames True Temper Holding Corp. ("Clopay Ames"), a subsidiary of Griffon, entered into a $375,000 secured term Loan ("Term Loan") and a $125,000 asset based lending agreement ("ABL").On November 30, 2010, Clopay Ames, as required under the Term Loan agreement, entered into an interest rate swap on a notional amount of $200,000 of the Term Loan. The agreement fixed the LIBOR component of the Term Loan interest rate at 2.085% for the notional amount of the swap.On March 17, 2011, the Term Loan and swap were terminated, and on March 18, 2011, the ABL was terminated, in connection with the issuance of the Senior Notes and Credit Agreement.

[11] In March 2008, Telephonics entered into a credit agreement with JPMorgan Chase Bank, N.A., as administrative agent, and the lenders party thereto, pursuant to which the lenders agreed to provide a five-year, revolving credit facility of $100,000 (the "TCA"). The TCA terminated in connection with the Credit Agreement.

NOTE 1 – DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION

About Griffon Corporation

Griffon Corporation (the “Company” or “Griffon”), is a diversified management and holding company that conducts business through wholly-owned subsidiaries. Griffon oversees the operations of its subsidiaries, allocates resources among them and manages their capital structures. Griffon provides direction and assistance to its subsidiaries in connection with acquisition and growth opportunities as well as in connection with divestitures. In order to further diversify, Griffon also seeks out, evaluates and, when appropriate, will acquire additional businesses that offer potentially attractive returns on capital.

Griffon currently conducts its operations through three segments:

• Home & Building Products (“HBP”) consists of two companies, Ames True Temper, Inc. (“ATT”) and Clopay Building Products Company, Inc. (“CBP”):

- ATT is a global provider of non-powered landscaping products that make work easier for homeowners and professionals.

- CBP is a leading manufacturer and marketer of residential, commercial and industrial garage doors to professional installing dealers and major home center retail chains.

• Telephonics Corporation (“Telephonics”) designs, develops and manufactures high-technology integrated information, communication and sensor system solutions to military and commercial markets worldwide.

• Clopay Plastic Products Company, Inc. (“Plastics”) is an international leader in the development and production of embossed, laminated and printed specialty plastic films used in a variety of hygienic, health-care and industrial applications.

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, these financial statements do not include all the information and footnotes required by U.S. GAAP for complete financial statements. As such, they should be read with reference to Griffon’s Annual Report on Form 10-K for the year ended September 30, 2011, which provides a more complete explanation of Griffon’s accounting policies, financial position, operating results, business properties and other matters. In the opinion of management, these financial statements reflect all adjustments considered necessary for a fair statement of interim results. Griffon’s HBP operations are seasonal and the results of any interim period are not necessarily indicative of the results for the full year.

The condensed consolidated balance sheet information at September 30, 2011 was derived from the audited financial statements included in Griffon’s Annual Report on Form 10-K for the year ended September 30, 2011.

The consolidated financial statements include the accounts of Griffon Corporation and all subsidiaries. Intercompany accounts and transactions are eliminated on consolidation.

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reporting periods. These estimates may be adjusted due to changes in economic, industry or customer financial conditions, as well as changes in technology or demand. Significant estimates include allowances for doubtful accounts receivable and returns, net realizable value of inventories, restructuring reserves, valuation of goodwill and intangible assets, percentage of completion method of accounting, pension assumptions, useful lives associated with depreciation and amortization of intangible and fixed assets, warranty reserves, sales incentive accruals, stock based compensation assumptions, income taxes and tax valuation reserves, environmental reserves, legal reserves, insurance reserves and the valuation of discontinued assets and liabilities, and the accompanying disclosures. These estimates are based on management’s best knowledge of current events and actions Griffon may undertake in the future. Actual results may ultimately differ from these estimates.

Certain amounts in the prior year have been reclassified to conform to current year presentation.

Stockholders' Equity Note Disclosure [Text Block]

NOTE 9 — SHAREHOLDERS’ EQUITY

During the first, second and third quarters of 2012, the Board of Directors approved three quarterly cash dividends of $0.02 per common share, which were paid on December 27, 2011, March 27, 2012 and June 26, 2012, to holders of common stock as of close of business on November 29, 2011, February 28, 2012 and May 29, 2012, respectively. $1,190 and $3,564 was recorded to retained earnings for the dividend for the three and nine months ended June 30, 2012, respectively. Dividends paid on allocated shares in the ESOP were used to pay down the ESOP loan and were recorded as a reduction in expense. A dividend payable was established for the holders of restricted shares; such payable will be released upon vesting of the underlying restricted shares.

On August 2, 2012, the Board of Directors declared a fourth quarterly cash dividend of $0.02 per share, payable on September 25, 2012 to shareholders of record as of the close of business on August 28, 2012.

Griffon expenses the fair value of equity compensation grants over the related vesting period. Compensation cost related to stock-based awards with graded vesting are amortized using the straight-line attribution method.

In February 2011, shareholders approved the Griffon Corporation 2011 Equity Incentive Plan (“Incentive Plan”) under which awards of performance shares, performance units, stock options, stock appreciation rights, restricted shares, deferred shares and other stock-based awards may be granted. Options granted under the Incentive Plan may be either “incentive stock options” or nonqualified stock options, generally expire ten years after the date of grant and must be granted at an exercise price of not less than 100% of the fair market value at the date of grant. The maximum number of shares of common stock available for award under the Incentive Plan is 3,000,000 (600,000 of which may be issued as incentive stock options) plus any shares underlying awards outstanding on the effective date of the Incentive Plan under the 2006 Incentive Plan that are subsequently cancelled or forfeited. As of June 30, 2012, 1,770,509 shares were available for grant.

All grants outstanding under the Griffon Corporation 2001 Stock Option Plan, 2006 Equity Incentive Plan and Outside Director Stock Award Plan will continue under their terms; no additional awards will be granted under such plans.

During the first quarter of 2012, Griffon granted 309,500 restricted shares with three-year cliff vesting, 191,000 of which are also subject to certain performance conditions, with a total fair value of $2,881, or a weighted average fair value of $9.31 per share.

During the second quarter of 2012, Griffon granted 110,000 restricted shares, 82,500 of which are three-year cliff vesting and 27,500 of which vest equally over 3 years; 37,500 of the 110,000 shares are subject to certain performance conditions. The total fair value of these grants is $1,119, or a weighted average fair value of $9.83 per share.

During the third quarter of 2012, Griffon granted 2,000 restricted shares with three-year cliff vesting. The total fair value of these grants is $19, or a weighted average fair value of $9.33 per share.

During the second quarter of 2011, Griffon granted 590,000 performance shares. Prior to the change in the terms of the grant, the performance shares had a fair value of $7,346, or a weighted average fair value of $12.45 per share, and cliff vested when either Griffon’s common stock closed at or above $16 per share for twenty consecutive trading days or 7 years from the date of grant, whichever came first. In January 2012, the terms of the grant were modified such that the price of Griffon common stock must close at or above $16 per share for thirty consecutive trading days on or prior to January 10, 2016 in order for the shares to vest; otherwise, the shares will be forfeited. The unamortized portion of the original fair value of approximately $6,400 will be expensed over the new service period of 32 months beginning January 2012.

For the three and nine months ended June 30, 2012, stock based compensation expense totaled $2,691 and $7,599, respectively. For the three and nine months ended June 30, 2011, stock based compensation expense totaled $2,120 and $6,767, respectively.

In August 2011, Griffon’s Board of Directors authorized the repurchase of up to $50,000 of Griffon’s outstanding common stock. Under this repurchase program, the Company may, from time to time, purchase shares of its common stock, depending upon market conditions, in open market or privately negotiated transactions, including pursuant to a 10b5-1 plan. In the first quarter of 2012, Griffon purchased 283,400 shares of common stock, for a total of $2,351, or $8.29 per share. In the third quarter of 2012, Griffon purchased 417,667 shares of common stock, for a total of $3,320, or $7.95 per share; in total, Griffon has purchased 866,446 shares of common stock, for a total of $6,980, or $8.06 per share, under this repurchase program. $43,020 remains under the $50,000 authorization. Subsequent to June 30, 2012, Griffon purchased 66,199 shares of common stock, for a total of $560, or $8.47 per share.

Income Tax Disclosure [Text Block]

NOTE 7 – INCOME TAXES

The tax rate for the current quarter was a provision of 39.7%, compared to a benefit of 81.3% in the prior year quarter. The current quarter’s rate reflects the benefit from the release of previously established reserves for uncertain tax positions on conclusion of certain tax audits. The prior year effective rate included benefits arising on the filing of the tax returns in various jurisdictions and the impact of tax planning initiatives related to unremitted foreign earnings. Excluding discrete items, the current quarter’s rate was 50.5%, which reflects the impact of permanent differences not deductible in determining taxable income, mainly limited deductibility of restricted stock, as well as the impact of tax reserves and a change in earnings mix between domestic and non-domestic operations. Excluding discrete items, the prior year quarter’s rate was 77.7%, which reflected the combined effects of the nominal pretax income in the quarter with a forecast full year pretax loss for 2011, as well as fluctuations in the full year expected effective tax rate driven by changes in earnings mix between domestic and non-domestic operations.

The tax rate for the nine months ended June 30, 2012 was a provision of 45.0%, compared to a benefit of 48.5% in the prior year. The current year rate reflects the benefit from the release of previously established reserves for uncertain tax positions on conclusion of certain tax audits. The prior year effective rate included benefits arising in connection with the retroactively extended research tax credit signed into law on December 22, 2010, the filing of tax returns in various jurisdictions, and the impact of tax planning initiatives related to unremitted foreign earnings. Excluding discrete items, the current year rate was 51.6%, which reflected the impact of permanent differences that are not deductible in determining taxable income, mainly limited deductibility of restricted stock, as well as the impact of tax reserves and a change in earnings mix between domestic and non-domestic operations. Excluding discrete items, the prior year rate was a benefit of 27.0% and reflected the impact of permanent differences not deductible in determining taxable income as well as the impact of tax reserves and changes in earnings mix.

(a)	On March 17, 2011, in an unregistered offering through a private placement under Rule 144A, Griffon issued, at par, $550,000 of 7.125% Senior Notes due in 2018; interest is payable semi-annually. On August 9, 2011, Griffon exchanged all of the Senior Notes for substantially identical Senior Notes registered under the Securities Act of 1933 (“Senior Notes”), via an exchange offer.
	The Senior Notes can be redeemed prior to April 1, 2014 at a price of 100% of principal plus a make-whole premium and accrued interest; on or after April 1, 2014, the Senior Notes can be redeemed at a certain price (declining from 105.344% of principal on or after April 1, 2014 to 100% of principal on or after April 1, 2017), plus accrued interest. Proceeds from the Senior Notes were used to pay down the outstanding borrowings under a senior secured term loan facility and two senior secured revolving credit facilities of certain of the Company’s subsidiaries. The Senior Notes are senior unsecured obligations of Griffon guaranteed by certain domestic subsidiaries, and are subject to certain covenants, limitations and restrictions.
	On March 18, 2011, Griffon entered into a five-year $200,000 Revolving Credit Facility (“Credit Agreement”), which includes a letter of credit sub-facility with a limit of $50,000, a multi-currency sub-facility of $50,000 and a swingline sub-facility with a limit of $30,000. Borrowings under the Credit Agreement may be repaid and re-borrowed at any time, subject to final maturity of the facility or the occurrence of a default or event of default under the Credit Agreement. Interest is payable on borrowings at either a LIBOR or base rate benchmark rate plus an applicable margin, which will adjust based on financial performance. The margins are 1.75% for base rate loans and 2.75% for LIBOR loans, in each case without a floor. The Credit Agreement has certain financial maintenance tests including a maximum total leverage ratio, a maximum senior secured leverage ratio and a minimum interest coverage ratio as well as customary affirmative and negative covenants and events of default. The Credit Agreement also includes certain restrictions, such as limitations on the incurrence of indebtedness and liens and the making of restricted payments and investments. Borrowings under the Credit Agreement are guaranteed by certain domestic subsidiaries and are secured, on a first priority basis, by substantially all assets of the Company and the guarantors.
	At June 30, 2012, there were $21,516 of standby letters of credit outstanding under the Credit Agreement; $178,484 was available for borrowing at that date.

(b)	On December 21, 2009, Griffon issued $100,000 principal of 4% convertible subordinated notes due 2017 (the “2017 Notes”). The initial conversion rate of the 2017 Notes was 67.0799 shares of Griffon’s common stock per $1,000 principal amount of notes, corresponding to an initial conversion price of $14.91 per share, a 23% conversion premium over the $12.12 closing price on December 15, 2009. When a cash dividend is declared that would result in an adjustment to the conversion ratio of less than 1%, any adjustment to the conversion ratio is deferred until the first to occur of (i) actual conversion, (ii) the 42nd trading day prior to maturity of the notes, and (iii) such time as the cumulative adjustment equals or exceeds 1%. As of September 25, 2012, aggregate dividends of $0.08 per share would result in a cumulative change in the conversion rate of approximately 0.9%. Griffon used 8.75% as the nonconvertible debt-borrowing rate to discount the 2017 Notes and will amortize the debt discount through January 2017. At issuance, the debt component of the 2017 Notes was $75,437 and debt discount was $24,563. At June 30, 2012 and September 30, 2011, the 2017 Notes had a capital in excess of par component, net of tax, of $15,720.
(c)	On December 20, 2010, Griffon entered into two second lien real estate mortgages to secure new loans totaling $11,834. The loans mature in February 2016, are collateralized by the related properties and are guaranteed by Griffon. The loans bear interest at a rate of LIBOR plus 3% with the option to swap to a fixed rate.
	Griffon has other real estate mortgages, collateralized by real property, which bear interest at 6.3% and mature in 2016. On October 3, 2011, the mortgage at Russia, Ohio was paid in full, on maturity.
(d)	Griffon’s Employee Stock Ownership Plan (“ESOP”) entered into a loan agreement in August 2010 to borrow $20,000 over a one-year period. The proceeds were used to purchase 1,874,737 shares of Griffon common stock in the open market for $19,973. The loan bears interest at a) LIBOR plus 2.5% or b) the lender’s prime rate, at Griffon’s option. In November 2011, Griffon exercised an option to convert the outstanding loan to a five-year term loan; principal is payable in quarterly installments of $250, beginning December 2011, with a balloon payment of $15,223 due at maturity (November 2016). The loan is secured by shares purchased with the proceeds of the loan, and repayment is guaranteed by Griffon. At June 30, 2012, $19,223 was outstanding.
	In addition, the ESOP has a loan agreement, guaranteed by Griffon, which requires quarterly principal payments of $156 and interest through the extended expiration date of December 2013 at which time the $3,125 balance of the loan, and any outstanding interest, will be payable. The primary purpose of this loan was to purchase 547,605 shares of Griffon’s common stock in October 2008. The loan is secured by shares purchased with the proceeds of the loan, and repayment is guaranteed by Griffon. The loan bears interest at rates based upon the prime rate or LIBOR. At June 30, 2012, $3,906 was outstanding.
(e)	In October 2006, CBP entered into a capital lease totaling $14,290 for real estate in Troy, Ohio. The lease matures in 2021, bears interest at a fixed rate of 5.1%, is secured by a mortgage on the real estate and is guaranteed by Griffon.
(f)	At June 30, 2012 and September 30, 2011, Griffon had $532 of 4% convertible subordinated notes due 2023 (the “2023 Notes”) outstanding. Holders of the 2023 Notes may require Griffon to repurchase all or a portion of their 2023 Notes on July 18, 2013 and 2018, if Griffon’s common stock price is below the conversion price of the 2023 Notes, as well as upon a change in control. An adjustment to the conversion rate will be required as the result of payment of a cash dividend only if such adjustment would be greater than 1% (or at such time as the cumulative impact on the conversion rate reaches 1% in the aggregate). As of September 25, 2012, aggregate dividends of $0.08 per share would result in a cumulative change in the conversion rate of approximately 0.9%. At June 30, 2012 and September 30, 2011, the 2023 Notes had no capital in excess of par value component as substantially all of these notes were put to Griffon at par and settled in July 2010.

(g)	In November 2010, Clopay Europe GMBH (“Clopay Europe”) entered into a €10,000 revolving credit facility and a €20,000 term loan. The facility accrues interest at Euribor plus 2.1% per annum, and the term loan accrues interest at Euribor plus 2.2% per annum. The revolving facility matures in November 2012, but is renewable upon mutual agreement with the bank. In July 2011, the full €20,000 was drawn on the Term Loan, with a portion of the proceeds used to repay borrowings under the revolving credit facility. The term loan is payable in ten equal quarterly installments which began in September 2011, with maturity in December 2013. Under the term loan, Clopay Europe is required to maintain a certain minimum equity to assets ratio and keep leverage below a certain level, defined as the ratio of total debt to EBITDA. At June 30, 2012, there was €1,000 borrowed on the revolving credit with €9,000 available for borrowing.
(h)	In February 2012, Clopay do Brazil, a subsidiary of Plastics, borrowed $4,000 at a rate of 104.5% of Brazilian CDI. The loan was used to refinance existing loans and is collateralized by accounts receivable and a 50% guaranty by Plastics and is to be repaid in four equal, semi-annual installments of principal plus accrued interest beginning in August 2012. Clopay do Brazil also maintains a line of credit of approximately $1,700. Interest on borrowings accrue at a rate of Brazilian CDI plus 6.0%. At June 30, 2012 there was approximately $1,346 borrowed under the line.
(i)	In connection with the ATT acquisition, Clopay Ames True Temper Holding Corp. (“Clopay Ames”), a subsidiary of Griffon, entered into a $375,000 secured term Loan (“Term Loan”) and a $125,000 asset based lending agreement (“ABL”).
	On November 30, 2010, Clopay Ames, as required under the Term Loan agreement, entered into an interest rate swap on a notional amount of $200,000 of the Term Loan. The agreement fixed the LIBOR component of the Term Loan interest rate at 2.085% for the notional amount of the swap.
	On March 17, 2011, the Term Loan and swap were terminated, and on March 18, 2011, the ABL was terminated, in connection with the issuance of the Senior Notes and Credit Agreement.
(j)	In March 2008, Telephonics entered into a credit agreement with JPMorgan Chase Bank, N.A., as administrative agent, and the lenders party thereto, pursuant to which the lenders agreed to provide a five-year, revolving credit facility of $100,000 (the “TCA”). The TCA terminated in connection with the Credit Agreement.
(k)	Includes capital leases.

At June 30, 2012, Griffon and its subsidiaries were in compliance with the terms and covenants of its credit and loan agreements.

During the second quarter of 2011, in connection with the termination of the Term Loan, ABL and Telephonics credit agreement, Griffon recorded a $26,164 loss on extinguishment of debt consisting of $21,617 of deferred financing charges and original issuer discounts, a call premium of $3,703 on the Term Loan, and $844 of swap and other breakage costs.

EARNINGS PER SHARE (EPS)

9 Months Ended

Earnings Per Share [Text Block]

NOTE 10 – EARNINGS PER SHARE (EPS)

Basic EPS was calculated by dividing income available to common shareholders by the weighted average number of shares of common stock outstanding during the period. Diluted EPS was calculated by dividing income available to common shareholders by the weighted average number of shares of common stock outstanding plus additional common shares that could be issued in connection with stock based compensation. The 2023 Notes and the 2017 Notes were anti-dilutive due to the conversion price being greater than the weighted-average stock price during the periods presented. Due to the net loss during the nine months ended June 30, 2011, the incremental shares from stock based compensation are anti-dilutive.

The following table is a reconciliation of the share amounts (in thousands) used in computing earnings per share:

	Three Months Ended June 30,				Nine Months Ended June 30,
	2012		2011		2012		2011
Weighted average shares outstanding - basic		56,034		59,606		56,032		59,387
Incremental shares from stock based compensation		1,461		919		1,279		—
Weighted average shares outstanding - diluted		57,495		60,525		57,311		59,387
Anti-dilutive options excluded from diluted EPS computation		963		1,200		1,202		1,200
Anti-dilutive restricted stock excluded from diluted EPS computation		—		850		—		850

Griffon has the intent and ability to settle the principal amount of the 2017 Notes in cash, as such, the potential issuance of shares related to the principal amount of the 2017 Notes does not affect diluted shares.

[1] On March 17, 2011, in an unregistered offering through a private placement under Rule 144A, Griffon issued, at par, $550,000 of 7.125% Senior Notes due in 2018; interest is payable semi-annually. On August 9, 2011, Griffon exchanged all of the Senior Notes for substantially identical Senior Notes registered under the Securities Act of 1933 ("Senior Notes"), via an exchange offer.The Senior Notes can be redeemed prior to April 1, 2014 at a price of 100% of principal plus a make-whole premium and accrued interest; on or after April 1, 2014, the Senior Notes can be redeemed at a certain price (declining from 105.344% of principal on or after April 1, 2014 to 100% of principal on or after April 1, 2017), plus accrued interest. Proceeds from the Senior Notes were used to pay down the outstanding borrowings under a senior secured term loan facility and two senior secured revolving credit facilities of certain of the Company's subsidiaries. The Senior Notes are senior unsecured obligations of Griffon guaranteed by certain domestic subsidiaries, and are subject to certain covenants, limitations and restrictions.On March 18, 2011, Griffon entered into a five-year $200,000 Revolving Credit Facility ("Credit Agreement"), which includes a letter of credit sub-facility with a limit of $50,000, a multi-currency sub-facility of $50,000 and a swingline sub-facility with a limit of $30,000. Borrowings under the Credit Agreement may be repaid and re-borrowed at any time, subject to final maturity of the facility or the occurrence of a default or event of default under the Credit Agreement. Interest is payable on borrowings at either a LIBOR or base rate benchmark rate plus an applicable margin, which will adjust based on financial performance. The margins are 1.75% for base rate loans and 2.75% for LIBOR loans, in each case without a floor. The Credit Agreement has certain financial maintenance tests including a maximum total leverage ratio, a maximum senior secured leverage ratio and a minimum interest coverage ratio as well as customary affirmative and negative covenants and events of default. The Credit Agreement also includes certain restrictions, such as limitations on the incurrence of indebtedness and liens and the making of restricted payments and investments. Borrowings under the Credit Agreement are guaranteed by certain domestic subsidiaries and are secured, on a first priority basis, by substantially all assets of the Company and the guarantors. At June 30, 2012, there were $21,516 of standby letters of credit outstanding under the Credit Agreement; $178,484 was available for borrowing at that date.

[2] On December 21, 2009, Griffon issued $100,000 principal of 4% convertible subordinated notes due 2017 (the "2017 Notes"). The initial conversion rate of the 2017 Notes was 67.0799 shares of Griffon's common stock per $1,000 principal amount of notes, corresponding to an initial conversion price of $14.91 per share, a 23% conversion premium over the $12.12 closing price on December 15, 2009. When a cash dividend is declared that would result in an adjustment to the conversion ratio of less than 1%, any adjustment to the conversion ratio is deferred until the first to occur of (i) actual conversion, (ii) the 42nd trading day prior to maturity of the notes, and (iii) such time as the cumulative adjustment equals or exceeds 1%. As of September 25, 2012, aggregate dividends of $0.08 per share would result in a cumulative change in the conversion rate of approximately 0.9%. Griffon used 8.75% as the nonconvertible debt-borrowing rate to discount the 2017 Notes and will amortize the debt discount through January 2017. At issuance, the debt component of the 2017 Notes was $75,437 and debt discount was $24,563. At June 30, 2012 and September 30, 2011, the 2017 Notes had a capital in excess of par component, net of tax, of $15,720.

[3] On December 20, 2010, Griffon entered into two second lien real estate mortgages to secure new loans totaling $11,834. The loans mature in February 2016, are collateralized by the related properties and are guaranteed by Griffon. The loans bear interest at a rate of LIBOR plus 3% with the option to swap to a fixed rate.Griffon has other real estate mortgages, collateralized by real property, which bear interest at 6.3% and mature in 2016. On October 3, 2011, the mortgage at Russia, Ohio was paid in full, on maturity.

[4] Griffon's Employee Stock Ownership Plan ("ESOP") entered into a loan agreement in August 2010 to borrow $20,000 over a one-year period. The proceeds were used to purchase 1,874,737 shares of Griffon common stock in the open market for $19,973. The loan bears interest at a) LIBOR plus 2.5% or b) the lender's prime rate, at Griffon's option. In November 2011, Griffon exercised an option to convert the outstanding loan to a five-year term loan; principal is payable in quarterly installments of $250, beginning December 2011, with a balloon payment of $15,223 due at maturity (November 2016). The loan is secured by shares purchased with the proceeds of the loan, and repayment is guaranteed by Griffon. At June 30, 2012, $19,223 was outstanding.In addition, the ESOP has a loan agreement, guaranteed by Griffon, which requires quarterly principal payments of $156 and interest through the extended expiration date of December 2013 at which time the $3,125 balance of the loan, and any outstanding interest, will be payable. The primary purpose of this loan was to purchase 547,605 shares of Griffon's common stock in October 2008. The loan is secured by shares purchased with the proceeds of the loan, and repayment is guaranteed by Griffon. The loan bears interest at rates based upon the prime rate or LIBOR. At June 30, 2012, $3,906 was outstanding.

[5] In October 2006, CBP entered into a capital lease totaling $14,290 for real estate in Troy, Ohio. The lease matures in 2021, bears interest at a fixed rate of 5.1%, is secured by a mortgage on the real estate and is guaranteed by Griffon.

[6] At June 30, 2012 and September 30, 2011, Griffon had $532 of 4% convertible subordinated notes due 2023 (the "2023 Notes") outstanding. Holders of the 2023 Notes may require Griffon to repurchase all or a portion of their 2023 Notes on July 18, 2013 and 2018, if Griffon's common stock price is below the conversion price of the 2023 Notes, as well as upon a change in control. An adjustment to the conversion rate will be required as the result of payment of a cash dividend only if such adjustment would be greater than 1% (or at such time as the cumulative impact on the conversion rate reaches 1% in the aggregate). As of September 25, 2012, aggregate dividends of $0.08 per share would result in a cumulative change in the conversion rate of approximately 0.9%. At June 30, 2012 and September 30, 2011, the 2023 Notes had no capital in excess of par value component as substantially all of these notes were put to Griffon at par and settled in July 2010.

[7] In November 2010, Clopay Europe GMBH ("Clopay Europe") entered into a €10,000 revolving credit facility and a €20,000 term loan. The facility accrues interest at Euribor plus 2.1% per annum, and the term loan accrues interest at Euribor plus 2.2% per annum. The revolving facility matures in November 2012, but is renewable upon mutual agreement with the bank. In July 2011, the full €20,000 was drawn on the Term Loan, with a portion of the proceeds used to repay borrowings under the revolving credit facility. The term loan is payable in ten equal quarterly installments which began in September 2011, with maturity in December 2013. Under the term loan, Clopay Europe is required to maintain a certain minimum equity to assets ratio and keep leverage below a certain level, defined as the ratio of total debt to EBITDA. At June 30, 2012, there was €1,000 borrowed on the revolving credit with €9,000 available for borrowing.

[8] In February 2012, Clopay do Brazil, a subsidiary of Plastics, borrowed $4,000 at a rate of 104.5% of Brazilian CDI. The loan was used to refinance existing loans and is collateralized by accounts receivable and a 50% guaranty by Plastics and is to be repaid in four equal, semi-annual installments of principal plus accrued interest beginning in August 2012. Clopay do Brazil also maintains a line of credit of approximately $1,700. Interest on borrowings accrue at a rate of Brazilian CDI plus 6.0%. At June 30, 2012 there was approximately $1,346 borrowed under the line.

[9] In connection with the ATT acquisition, Clopay Ames True Temper Holding Corp. ("Clopay Ames"), a subsidiary of Griffon, entered into a $375,000 secured term Loan ("Term Loan") and a $125,000 asset based lending agreement ("ABL").On November 30, 2010, Clopay Ames, as required under the Term Loan agreement, entered into an interest rate swap on a notional amount of $200,000 of the Term Loan. The agreement fixed the LIBOR component of the Term Loan interest rate at 2.085% for the notional amount of the swap.On March 17, 2011, the Term Loan and swap were terminated, and on March 18, 2011, the ABL was terminated, in connection with the issuance of the Senior Notes and Credit Agreement.

[10] In March 2008, Telephonics entered into a credit agreement with JPMorgan Chase Bank, N.A., as administrative agent, and the lenders party thereto, pursuant to which the lenders agreed to provide a five-year, revolving credit facility of $100,000 (the "TCA"). The TCA terminated in connection with the Credit Agreement.
