Accounting Policies [Abstract]
DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Description of business Griffon Corporation (the “Company” or “Griffon”) is a diversified management and holding company conducting 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. Headquartered in New York, N.Y., the Company was founded in 1959 and is incorporated in Delaware. Griffon is listed on the New York Stock Exchange and trades under the symbol GFF. Griffon currently conducts its operations through three reportable segments: • Home & Building Products (“HBP”) consists of two companies, The AMES Companies, Inc. (“AMES”) and Clopay Building Products (“CBP”): ◦ AMES is a global provider of non-powered landscaping products for homeowners and professionals. ◦ CBP is a leading manufacturer and marketer of residential, commercial and industrial garage doors to professional dealers and major home center retail chains. • Telephonics Corporation (“Telephonics”) designs, develops and manufactures high-technology integrated information, communication and sensor system solutions for military and commercial markets worldwide. • Clopay Plastic Products Company (“PPC”) 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. Consolidation The consolidated financial statements include the accounts of Griffon and all subsidiaries. Intercompany accounts and transactions have been eliminated in consolidation. The results of operations of acquired businesses are included from the dates of acquisitions. Earnings (Loss) per share Due to rounding, the sum of earnings per share of Continuing operations and Discontinued operations may not equal earnings per share of Net income. Discontinued operations – Installation Services In 2008, as a result of the downturn in the residential housing market, Griffon exited substantially all operating activities of its Installation Services segment which sold, installed and serviced garage doors and openers, fireplaces, floor coverings, cabinetry and a range of related building products, primarily for the new residential housing market. Operating results of substantially all of this segment have been reported as discontinued operations in the Consolidated Statements of Operations and Comprehensive Income (Loss) for all periods presented; Installation Services is excluded from segment reporting. At September 30, 2015 , Griffon’s assets and liabilities for discontinued operations primarily related to income taxes and product liability, warranty and environmental reserves. Reclassifications Certain amounts in prior years have been reclassified to conform to the current year presentation. Use of estimates 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, the valuation of assets and liabilities of discontinued operations, acquisition assumptions used 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. Cash and equivalents Griffon considers all highly liquid investments purchased with an initial maturity of three months or less to be cash equivalents. Cash equivalents primarily consist of overnight commercial paper, highly-rated liquid money market funds backed by U.S. Treasury securities and U.S. Agency securities, as well as insured bank deposits. Griffon had cash in non-U.S. bank accounts of approximately $31,700 and $34,500 at September 30, 2015 and 2014 , respectively. Substantially all U.S. cash and equivalents are in excess of FDIC insured limits. Griffon regularly evaluates the financial stability of all institutions and funds that hold its cash and equivalents. Fair value of financial instruments 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 value hierarchy, as outlined in the applicable accounting guidance, establishes a fair value hierarchy that requires the Company to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. A financial instrument’s categorization within the hierarchy is based on the lowest level of input that is significant to the fair value measurement. The accounting guidance establishes three levels of inputs that may be used to measure fair value, as follows: • Level 1 inputs are measured and recorded at fair value based upon quoted prices in active markets for identical assets. • Level 2 inputs include inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices in active markets for similar assets and liabilities, quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of assets or liabilities. • Level 3 inputs are unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions. The fair values of Griffon’s 2022 senior notes and 2017 4% convertible notes approximated $570,000 and $118,875 , respectively, on September 30, 2015 . Fair values were based upon quoted market prices (level 1 inputs). Insurance contracts with a value of $2,942 at September 30, 2015 are measured and recorded at fair value based upon quoted prices in active markets for similar assets (level 2 inputs) and are included in Other current assets on the consolidated balance sheet. Items Measured at Fair Value on a Recurring Basis At September 30, 2015, trading securities, measured at fair value based on quoted prices in active markets for similar assets (level 2 inputs), with a fair value of $1,374 ( $1,000 cost basis) were included in Prepaid and other current assets on the Consolidated Balance Sheets. During the current year, the Company settled all outstanding available-for-sale securities with proceeds totaling $8,891 and recognized a gain of $489 in Other income, and accordingly, a gain of $870 , net of tax, on available-for-sale securities was reclassified out of Accumulated other comprehensive income (loss) ("AOCI"). At September 30, 2014, available-for-sale securities, measured at fair value based on quoted prices in active markets for the underlying assets (level 1 inputs), and trading securities, measured at fair value based on quoted prices in active markets for similar assets (level 2 inputs), with values of $9,770 ( $8,400 cost basis) and $1,274 ( $1,000 cost basis), respectively, are included in Prepaid and other current assets on the Consolidated Balance Sheets. Unrealized gains and losses, net of deferred taxes, on available-for-sale securities are included in our Consolidated Balance Sheets as a component of AOCI. Realized and unrealized gains and losses on trading securities and realized gains and losses on available-for-sale securities are included in Other income in the Consolidated Statements of Operations and Comprehensive Income (Loss). In the normal course of business, Griffon’s operations are exposed to the effect of changes in foreign currency exchange rates. To manage these risks, Griffon may enter into various derivative contracts such as foreign currency exchange contracts, including forwards and options. During 2015 and 2014, Griffon entered into several such contracts in order to lock into a foreign currency rate for planned settlements of trade and inter-company liabilities payable in USD. At September 30, 2015 and 2014, Griffon had $25,531 and $4,975 of Australian dollar contracts at a weighted average rate of $1.43 and $1.14 , which qualified for hedge accounting. At inception, these hedges were all deemed effective as cash flow hedges with gains and losses related to changes in fair value deferred and recorded in Other comprehensive income (loss) and Prepaid and other current assets, or Accrued liabilities, until settlement. Upon settlement, gains and losses were recognized in the Consolidated Statements of Operations and Comprehensive Income (Loss) in Cost of goods and services. AOCI included deferred gains of $1,049 ( $682 , net of tax) and $386 ( $252 , net of tax) at September 30, 2015 and 2014, respectively. A gain of $1,223 was recorded in COGS during the year ended September 30, 2015 for settled contracts and no contracts settled during the year ended September 30, 2014. At September 30, 2015 , Griffon had $6,500 of Canadian dollar contracts at a weighted average rate of $1.33 . As of September 30, 2014, Griffon had $3,197 of Australian dollar contracts at a weighted average rate of $1.14 . These contracts, which protect both Canadian and Australian operations from currency fluctuations for U.S. dollar based purchases, do not qualify for hedge accounting and a fair value loss of $274 and gain of $141 were recorded in Other assets and to Other income for the outstanding contracts, based on similar contract values (level 2 inputs), for the years ended September 30, 2015 and 2014, respectively. All contracts expire in 30 to 360 days . Pension plan assets with a fair value of $144,625 at September 30, 2015 , are measured and recorded at fair value based upon quoted prices in active markets for identical assets (level 1 inputs) and quoted market prices for similar assets (level 2 inputs). Non-U.S. currency translation Assets and liabilities of non-U.S. subsidiaries, where the functional currency is not the U.S. dollar, have been translated at year-end exchange rates and profit and loss accounts have been translated using weighted average exchange rates. Adjustments resulting from currency translation have been recorded in the equity section of the balance sheet in AOCI as cumulative translation adjustments. Cumulative translation adjustments were a loss of $60,178 and $3,820 at September 30, 2015 and 2014 , respectively. Assets and liabilities of an entity that are denominated in currencies other than that entity’s functional currency are remeasured into the functional currency using period end exchange rates, or historical rates where applicable to certain balances. Gains and losses arising on remeasurements are recorded within the Consolidated Statement of Operations and Comprehensive Income (Loss) as a component of Other income (expense). Revenue recognition Revenue is recognized when the following circumstances are satisfied: a) persuasive evidence of an arrangement exists, b) delivery has occurred, title has transferred or services are rendered, c) price is fixed and determinable and d) collectability is reasonably assured. Goods are sold on terms that transfer title and risk of loss at a specified location. Revenue recognition from product sales occurs when all factors are met, including transfer of title and risk of loss, which occurs either upon shipment or upon receipt by customers at the location specified in the terms of sale. Other than standard product warranty provisions, sales arrangements provide for no other significant post-shipment obligations. From time to time and for certain customers, rebates and other sales incentives, promotional allowances or discounts are offered, typically related to customer purchase volumes, all of which are fixed or determinable and are classified as a reduction of revenue and recorded at the time of sale. Griffon provides for sales returns allowances based upon historical returns experience. Telephonics earns a substantial portion of its revenue as either a prime or subcontractor from contract awards with the U.S. Government, as well as non-U.S. governments and other commercial customers. These formal contracts are typically long-term in nature, usually greater than one year . Revenue and profits from these long-term fixed price contracts are recognized under the percentage-of-completion method of accounting. Revenue and profits on fixed-price contracts that contain engineering as well as production requirements are recorded based on the ratio of total actual incurred costs to date to the total estimated costs for each contract (cost-to-cost method). Using the cost-to-cost method, revenue is recorded at amounts equal to the ratio of actual cumulative costs incurred divided by total estimated costs at completion, multiplied by the total estimated contract revenue, less the cumulative revenue recognized in prior periods. The profit recorded on a contract using this method is equal to the current estimated total profit margin multiplied by the cumulative revenue recognized, less the amount of cumulative profit previously recorded for the contract in prior periods. As this method relies on the substantial use of estimates, these projections may be revised throughout the life of a contract. Components of this formula and ratio that may be estimated include gross profit margin and total costs at completion. The cost performance and estimates to complete on long-term contracts are reviewed, at a minimum, on a quarterly basis, as well as when information becomes available that would necessitate a review of the current estimate. Adjustments to estimates for a contract’s estimated costs at completion and estimated profit or loss often are required as experience is gained, and as more information is obtained, even though the scope of work required under the contract may or may not change, or if contract modifications occur. The impact of such adjustments or changes to estimates is made on a cumulative basis in the period when such information has become known. In 2015, 2014 and 2013, income from operations included net favorable/(unfavorable) catch-up adjustments approximating $(400) , $(400) and $3,400 , respectively. Gross profit is affected by a variety of factors, including the mix of products, systems and services, production efficiencies, price competition and general economic conditions. Revenue and profits on cost-reimbursable type contracts are recognized as allowable costs, and are incurred on the contract at an amount equal to the allowable costs plus the estimated profit on those costs. The estimated profit on a cost-reimbursable contract may be fixed or variable based on the contractual fee arrangement. Incentive and award fees on these contracts are recorded as revenue when the criteria under which they are earned are reasonably assured of being met and can be estimated. For contracts in which anticipated total costs exceed the total expected revenue, an estimated loss is recognized in the period when identifiable. A provision for the entire amount of the estimated loss is recorded on a cumulative basis. The estimated remaining costs to complete loss contracts as of September 30, 2015 was $10,600 and is recorded as a reduction to gross margin on the Consolidated Statements of Operations and Comprehensive Income (Loss). This loss had an immaterial impact on Griffon's Consolidated Financial Statements. Amounts representing contract change orders or claims are included in revenue only when they can be reliably estimated and their realization is probable, and are determined on a percentage-of-completion basis measured by the cost-to-cost method. From time to time, Telephonics may combine contracts if they are negotiated together, have specific requirements to combine, or are otherwise closely related. Contracts are segmented based on customer requirements. Accounts receivable, allowance for doubtful accounts and concentrations of credit risk Accounts receivable is composed principally of trade accounts receivable that arise from the sale of goods or services on account, and is stated at historical cost. A substantial portion of Griffon’s trade receivables are from customers of HBP, of which the largest customer is Home Depot, whose financial condition is dependent on the construction and related retail sectors of the economy. In addition, a significant portion of Griffon’s trade receivables are from one PPC customer, P&G, whose financial condition is dependent on the consumer products and related sectors of the economy. As a percentage of consolidated accounts receivable, U.S. Government related programs were 13% , P&G was 8% and Home Depot was 10% . Griffon performs continuing evaluations of the financial condition of its customers, and although Griffon generally does not require collateral, letters of credit may be required from customers in certain circumstances. Trade receivables are recorded at the stated amount, less allowance for doubtful accounts and, when appropriate, for customer program reserves and cash discounts. The allowance represents estimated uncollectible receivables associated with potential customer defaults on contractual obligations (usually due to customers’ potential insolvency). The allowance for doubtful accounts includes amounts for certain customers where a risk of default has been specifically identified, as well as an amount for customer defaults based on a formula when it is determined the risk of some default is probable and estimable, but cannot yet be associated with specific customers. The provision related to the allowance for doubtful accounts is recorded in Selling, general and administrative ("SG&A") expenses. The Company writes-off accounts receivable when they are deemed to be uncollectible. Customer program reserves and cash discounts are netted against accounts receivable when it is customer practice to reduce invoices for these amounts. The amounts netted against accounts receivable in 2015 and 2014 were $7,507 and $9,295 , respectively. All accounts receivable amounts are expected to be collected in less than one year. The Company does not currently have customers or contracts that prescribe specific retainage provisions. Contract costs and recognized income not yet billed Contract costs and recognized income not yet billed consists of amounts accounted for under the percentage of completion method of accounting, recoverable costs and accrued profit that cannot yet be invoiced under the terms of certain long-term contracts. Amounts will be invoiced when applicable contract terms, such as the achievement of specified milestones or product delivery, are met. At September 30, 2015 and 2014, approximately $16,500 and $8,400 , respectively, of contract costs and recognized income not yet billed were expected to be collected after one year. As of September 30, 2015 and 2014, the unbilled receivable balance included $ 2,800 and $2,200 , respectively, of reserves for contract risk. Inventories Inventories, stated at the lower of cost (first-in, first-out or average) or market, include material, labor and manufacturing overhead costs. Griffon’s businesses typically do not require inventory that is susceptible to becoming obsolete or dated. In general, Telephonics sells products in connection with programs authorized and approved under contracts awarded by the U.S. Government or agencies thereof and in accordance with customer specifications. PPC primarily produces fabricated materials used by customers in the production of their products and these materials are produced against orders from those customers. HBP produces doors and non-powered lawn and garden tools in response to orders from customers of retailers and dealers or based on expected orders, as applicable. Property, plant and equipment Property, plant and equipment includes the historical cost of land, buildings, equipment and significant improvements to existing plant and equipment or, in the case of acquisitions, a fair market value appraisal of such assets completed at the time of acquisition. Expenditures for maintenance, repairs and minor renewals are expensed as incurred. When property or equipment is sold or otherwise disposed of, the related cost and accumulated depreciation is removed from the respective accounts and the gain or loss is recognized. No event or indicator of impairment occurred during the three years ended September 30, 2015, which would require additional impairment testing of property, plant and equipment. Depreciation expense, which includes amortization of assets under capital leases, was $62,144 , $59,488 and $62,911 for the years ended September 30, 2015 , 2014 and 2013 , respectively, and was calculated on a straight-line basis over the estimated useful lives of the assets. Depreciation included in SG&A expenses was $13,009 , $10,815 and $12,733 for the years ended September 30, 2015, 2014 and 2013. The remaining components of depreciation, attributable to manufacturing operations, are included in Cost of goods and services. Estimated useful lives for property, plant and equipment are as follows: buildings and building improvements, 25 to 40 years ; machinery and equipment, 2 to 15 years and leasehold improvements, over the term of the lease or life of the improvement, whichever is shorter. Capitalized interest costs included in Property, plant and equipment were $4,165 , $4,529 and $4,030 for the years ended September 30, 2015 , 2014 and 2013 , respectively. The original cost of fully-depreciated property, plant and equipment remaining in use at September 30, 2015 was approximately $18,146 . Goodwill and indefinite-lived intangibles Goodwill is the excess of the acquisition cost of a business over the fair value of the identifiable net assets acquired. Goodwill is not amortized, but is subject to an annual impairment test unless during an interim period, impairment indicators such as a significant change in the business climate exist. Griffon performed its annual impairment testing of goodwill as of September 30, 2015 . The performance of the test involves a two-step process. The first step involves comparing the fair value of Griffon’s reporting units with the reporting unit’s carrying amount, including goodwill. Griffon generally determines the fair value of its reporting units using the income approach methodology of valuation that includes the present value of expected future cash flows. This method uses market assumptions specific to Griffon’s reporting units. If the carrying amount of a reporting unit exceeds the reporting unit’s fair value, Griffon performs the second step of the goodwill impairment test to determine the amount of impairment loss. The second step compares the implied fair value of the reporting unit’s goodwill with the carrying amount of that goodwill. Griffon defines its reporting units as its three reportable segments: HBP, Telephonics and PPC. HBP consists of two components, AMES and CBP, which due to their similar economic characteristics, are aggregated into one reporting unit for goodwill testing. Griffon used 5 year projections and a 3.0% terminal value to which discount rates between 9% and 10% were applied to calculate each unit’s fair value. To substantiate fair values derived from the income approach methodology of valuation, the implied fair value was reconciled to Griffon’s market capitalization, the results of which supported the implied fair values. Any changes in key assumptions or management judgment with respect to a reporting unit or its prospects, which may result from a decline in Griffon’s stock price, a change in market conditions, market trends, interest rates or other factors outside Griffon’s control, or significant underperformance relative to historical or project future operating results, could result in a significantly different estimate of the fair value of the reporting units, which could result in a future impairment charge (level 3 inputs). Based upon the results of the annual impairment review, it was determined that the fair value of each reporting unit substantially exceeded the carrying value of the assets, as performed under step one, and no impairment existed. Similar to goodwill, Griffon tests indefinite-lived intangible assets at least annually and when indicators of impairment exist. Griffon uses a discounted cash flow method to calculate and compare the fair value of the intangible to its book value. This method uses market assumptions specific to Griffon’s reporting units, which are reasonable and supportable. If the fair value is less than the book value of the indefinite-lived intangibles, an impairment charge would be recognized. There was no impairment related to any goodwill or indefinite-lived intangible at September 30, 2015, 2014 or 2013. Definite-lived long-lived assets Amortizable intangible assets are carried at cost less accumulated amortization. For financial reporting purposes, definite-lived intangible assets are amortized on a straight-line basis over their useful lives, generally eight to twenty-five years . Long-lived assets and certain identifiable intangible assets to be held and used are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Determination of recoverability is based on an estimate of undiscounted future cash flows resulting from the use of the asset and its eventual disposition. There were no indicators of impairment during the three years ending September 30, 2015 . Income taxes Income taxes are accounted for under the liability method. Deferred taxes reflect the tax consequences on future years of differences between the tax basis of assets and liabilities and their financial reporting amounts. The carrying value of Griffon’s deferred tax assets is dependent upon Griffon’s ability to generate sufficient future taxable income in certain tax jurisdictions. Should Griffon determine that it is more likely than not that some portion of the deferred tax assets will not be realized, a valuation allowance against the deferred tax assets would be established in the period such determination was made. Griffon provides for uncertain tax positions and any related interest and penalties based upon Management’s assessment of whether a tax benefit is more likely than not of being sustained upon examination by tax authorities. At September 30, 2015 Griffon believes that it has appropriately accounted for all unrecognized tax benefits. As of September 30, 2015 , 2014 and 2013 , Griffon has recorded unrecognized tax benefits in the amount of $7,851 , $7,906 and $10,520 , respectively. Accrued interest and penalties related to income tax matters are recorded in the provision for income taxes. Research and development costs, shipping and handling costs and advertising costs Research and development costs not recoverable under contractual arrangements are charged to SG&A expense as incurred and amounted to $25,600 , $23,400 and $22,400 in 2015 , 2014 and 2013 , respectively. SG&A expenses include shipping and handling costs of $40,800 in 2015 , $42,400 in 2014 and $39,600 in 2013 and advertising costs, which are expensed as incurred, of $24,000 in 2015 , $24,000 in 2014 and $23,000 in 2013 . Risk, retention and insurance Griffon’s property and casualty insurance programs contain various deductibles that, based on Griffon’s experience, are reasonable and customary for a company of its size and risk profile. Griffon generally maintains deductibles for claims and liabilities related primarily to workers’ compensation, general, product and automobile liability as well as property damage and business interruption losses resulting from certain events. Griffon does not consider any of the deductibles to represent a material risk to Griffon. Griffon accrues for claim exposures that are probable of occurrence and can be reasonably estimated. Insurance is maintained to transfer risk beyond the level of self-retention and provides protection on both an individual claim and annual aggregate basis. Pension benefits Griffon sponsors defined and supplemental benefit pension plans for certain retired employees. Annual amounts relating to these plans are recorded based on actuarial projections, which include various actuarial assumptions, including discount rates, assumed rates of return, compensation increases and turnover rates. Actuarial assumptions used to determine pension liabilities, assets and expense are reviewed annually and modified based on current economic conditions and trends. The expected return on plan assets is determined based on the nature of the plan's investments and expectations for long-term rates of return. The discount rate used to measure obligations is based on a corporate bond spot-rate yield curve that matches projected future benefit payments, with the appropriate spot rate applicable to the timing of the projected future benefit payments. Assumptions used in determining Griffon’s obligations under the defined benefit pension plans are believed to be reasonable, based on experience and advice from independent actuaries; however, differences in actual experience or changes in assumptions may materially impact Griffon’s financial position or results of operations. All of the defined benefit plans are frozen and have ceased accruing benefits. Newly issued but not yet effective accounting pronouncements In May 2014, the FASB issued guidance on revenue from contracts with customers. The underlying principle is that an entity will recognize revenue to depict the transfer of goods or services to customers at an amount that the entity expects to be entitled to in exchange for those goods or services. The guidance provides a five-step analysis of transactions to determine when and how revenue is recognized. Other major provisions include capitalization of certain contract costs, consideration of time value of money in the transaction price, and allowing estimates of variable consideration to be recognized before contingencies are resolved, in certain circumstances. The guidance also requires enhanced disclosures regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from an entity's contracts with customers. This guidance permits the use of either the retrospective or cumulative effect transition method and is effective for the Company beginning in 2019; early adoption is permitted beginning in 2018. We have not yet selected a transition method and are currently evaluating the impact of the guidance on the Company's financial condition, results of operations and related disclosures. In August 2014, the FASB issued guidance on management's responsibility in evaluating whether there is substantial doubt about a company's ability to continue as a going concern and related footnote disclosures. Management will be required to evaluate, at each reporting period, whether there are conditions or events that raise substantial doubt about a company's ability to continue as a going concern within one year from the date the financial statements are issued. This guidance is effective prospectively for annual and interim reporting period beginning in 2017; implementation of this guidance is not expected to have a material effect on the Company’s financial condition or results of operations.

Business Combinations [Abstract]
ACQUISITIONS	ACQUISITIONS Griffon accounts for acquisitions under the acquisition method, in which assets acquired and liabilities assumed are recorded at fair value as of the date of acquisition using a method substantially similar to the good impairment test methodology (level 3 inputs). The operating results of the acquired companies are included in Griffon’s consolidated financial statements from the date of acquisition. On April 16, 2015, AMES acquired the assets of an operational wood mill in Champion, PA from the Babcock Lumber Company for $2,225 . The purchase price was preliminarily allocated to property, plant and equipment. The wood mill secures wood supplies, lowers overall production costs and mitigates risk associated with manufacturing handles for wheelbarrows and long-handled tools. On May 21, 2014, AMES acquired the Australian Garden and Tools business of Illinois Tool Works, Inc. (“Cyclone”) for approximately $40,000 . Cyclone, which was integrated with AMES, offers a full range of quality garden and hand tool products sold under various leading brand names including Cyclone®, Nylex® and Trojan®, designed to meet the requirements of both the Do-it-Yourself and professional trade segments. SG&A expenses included $2,363 of related acquisition costs in 2014. On December 31, 2013, AMES acquired Northcote Pottery™ (“Northcote”), founded in 1897 and a leading brand in the Australian outdoor planter and decor market, for approximately $22,000 . Northcote complements Southern Patio®, acquired in 2011, and adds to AMES’ existing lawn and garden operations in Australia. SG&A expenses included $798 of related acquisition costs in 2014. The accounts of the acquired companies, after adjustment to reflect fair market values (level 3 inputs), have been included in the consolidated financial statements from the date of acquisition; in each instance, acquired inventory was not significant.

Discontinued Operations and Disposal Groups [Abstract]
DISCONTINUED OPERATIONS	DISCONTINUED OPERATIONS In 2008, as a result of the downturn in the residential housing market, Griffon exited substantially all operating activities of its Installation Services segment which sold, installed and serviced garage doors and openers, fireplaces, floor coverings, cabinetry and a range of related building products, primarily for the new residential housing market. In 2008, Griffon sold eleven units, closed one unit and merged two units into CBP. Griffon substantially concluded its remaining disposal activities in 2009. Installation Services operating results have been reported as discontinued operations in the Consolidated Statements of Operations and Comprehensive Income (Loss) for all periods presented; Installation Services is excluded from segment reporting. There was no reported revenue in 2015, 2014 and 2013. In 2013, the Company recorded a $4,651 charge to discontinued operations increasing environmental and casualty insurance reserves. A portion of this charge relates to ongoing and potential future homeowner association claims related to the Installation Services business; claims experience has been greater than anticipated when reserves were initially established in 2008. The adjustment to environmental reserves relates to changes in status of and approach to cleanup requirements for businesses that were discontinued several years ago. At September 30, 2015 , Griffon’s assets and liabilities for discontinued operations primarily related to income taxes and product liability, warranty and environmental reserves. The following amounts related primarily to the Installation Services segment have been segregated from Griffon’s continuing operations and are reported as assets and liabilities of discontinued operations in the consolidated balance sheets: At September 30, At September 30, Assets of discontinued operations: Prepaid and other current assets $ 1,316 $ 1,624 Other long-term assets 2,175 2,126 Total assets of discontinued operations $ 3,491 $ 3,750 Liabilities of discontinued operations: Accrued liabilities, current $ 2,229 $ 3,282 Other long-term liabilities 3,379 3,830 Total liabilities of discontinued operations $ 5,608 $ 7,112

Restructuring and Related Activities [Abstract]
RESTRUCTURING AND OTHER RELATED CHARGES	RESTRUCTURING AND OTHER RELATED CHARGES During 2014, Telephonics recognized $4,244 in restructuring costs in connection with the closure of its Swedish facility and restructuring of operations, a voluntary early retirement plan and a reduction in force aimed at improving efficiency by combining functions and responsibilities, resulting in the elimination of 80 positions. In January 2013, AMES undertook to close certain of its U.S. manufacturing facilities and consolidate affected operations primarily into its Camp Hill and Carlisle, PA locations. The actions, completed at the end of the 2015 first quarter, improved manufacturing and distribution efficiencies, allow for in-sourcing of certain production currently performed by third party suppliers, and improved material flow and absorption of fixed costs. Since January 2013, AMES incurred pre-tax restructuring and related exit costs approximating $7,941 , comprised of cash charges of $4,016 and non-cash, asset-related charges of $3,925 ; the cash charges included $2,622 for one-time termination benefits and other personnel-related costs and $1,394 for facility exit costs. AMES had $19,964 of capital expenditures since January 2013. In 2014 and 2013 , HBP recognized $1,892 and $7,739 , respectively, of restructuring and other related exit costs. In 2014 and 2013 , restructuring and other related charges primarily related to one-time termination benefits, facility costs, other personnel costs and asset impairment charges related to the AMES' plant consolidation initiative and, in 2013, CBP's consolidation of its Auburn, Washington facility into its Russia, Ohio facility. Over a three year period from 2012, HBP headcount was reduced by 206 as a result of these actions. During 2013 , PPC Europe undertook to exit low margin businesses and eliminate approximately 80 positions, resulting in a restructuring cash charge of $4,773 . These actions were essentially complete at September 30, 2013. During 2013 , Telephonics recognized $750 of restructuring charges in connection with voluntary early retirement plan offerings and other costs related to changes in organizational structure and facilities; such charges were primarily personnel-related, reducing headcount by 185 employees since 2012. A summary of the restructuring and other related charges included in the line item “Restructuring and other related charges” in the Consolidated Statements of Operations recognized for 2013 and 2014 were as follows: Workforce Reduction Facilities & Exit Costs Other Related Costs Non-cash Facility and Other Total Amounts incurred in the year ended: September 30, 2013 $ 5,649 $ 1,668 $ 1,629 $ 4,316 $ 13,262 September 30, 2014 5,382 548 206 — 6,136 In 2015, no restructuring and other related charges were incurred.

(a) On February 27, 2014, in an unregistered offering through a private placement under Rule 144A, Griffon issued, at par, $600,000 of 5.25% Senior Notes due in 2022 (“Senior Notes”); interest is payable semi-annually on March 1 and September 1. Proceeds from the Senior Notes were used to redeem $550,000 of 7.125% senior notes due 2018, to pay a call and tender offer premium of $31,530 and to make interest payments of $16,716 , with the balance used to pay a portion of the related transaction fees and expenses. In connection with the issuance of the Senior Notes, all obligations under the $550,000 of 7.125% senior notes due in 2018 were discharged. The Senior Notes are senior unsecured obligations of Griffon guaranteed by certain domestic subsidiaries, and subject to certain covenants, limitations and restrictions. On June 18, 2014, Griffon exchanged all of the Senior Notes for substantially identical Senior Notes registered under the Securities Act of 1933 via an exchange offer. The fair value of Senior Notes approximated $570,000 on September 30, 2014 based upon quoted market prices (level 1 inputs). In connection with these transactions, Griffon capitalized $10,313 of underwriting fees and other expenses incurred related to the issuance and exchange of the Senior Notes, which will amortize over the term of such notes. Griffon recognized a loss on the early extinguishment of debt on the 7.125% senior notes aggregating $38,890 , comprised of the $31,530 tender offer premium, the write-off of $6,574 of remaining deferred financing fees and $786 of prepaid interest on defeased notes. (b) On March 13, 2015, Griffon amended its Revolving Credit Facility (“Credit Agreement”) to increase the credit facility from $225,000 to $250,000 , extend its maturity from March 28, 2019 to March 13, 2020, and modify certain other provisions of the facility. The facility includes a letter sub-facility with a limit of $50,000 (decreased from $60,000 ), and a multi-currency sub-facility of $50,000 . The Credit Agreement provides for same day borrowings of base rate loans in lieu of a swing line sub-facility. Borrowings under the Credit Agreement may be repaid and re-borrowed at any time, subject to final maturity of the facility, or the occurrence or event of default under the Credit Agreement. Interest is payable on borrowings at either a LIBOR or base rate benchmark rate, in each case without a floor, plus an applicable margin, which adjusts based on financial performance. Current margins are 1.00% for base rate loans and 2.00% for LIBOR loans. 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 negative covenants place limits on Griffon's ability to, among other things, incur indebtedness, incur liens, and make restricted payments and investments. The Credit Agreement also has a minimum liquidity covenant that requires cash and available borrowings under the Credit Agreement in the aggregate to equal or exceed $100 million during the six month period prior to maturity of the 2017 Notes (which mature on January 15, 2017); such covenant will no longer apply after payment in full of the 2017 Notes. Borrowings under the Credit Agreement are guaranteed by Griffon’s material domestic subsidiaries and are secured, on a first priority basis, by substantially all domestic assets of the Company and the guarantors and a pledge of not greater than 65% of the equity interest in each of Griffon’s material, first-tier foreign subsidiaries (except that a lien on the assets of Griffon’s material domestic subsidiaries securing a limited amount of the debt under the credit agreement relating to Griffon's Employee Stock Ownership Plan ranks pari passu with the lien granted on such assets under the Credit Agreement; see footnote (d) below). At September 30, 2015 , outstanding borrowings and standby letters of credit were $35,000 and $16,938 , respectively, under the Credit Agreement; $198,062 was available for borrowing at that date. (c) On December 21, 2009, Griffon issued $100,000 principal of 4% convertible subordinated notes due 2017 (the “2017 Notes”). The current conversion rate of the 2017 Notes is 69.3811 shares of Griffon’s common stock per $1 principal amount of notes, corresponding to a conversion price of $14.41 per share. Prior to July 15, 2016, if for at least 20 trading days out of the last 30 trading days during any fiscal quarter the closing price of Griffon's common stock is 130% or greater than the conversion price on each such trading day, then at any time during the immediately subsequent fiscal quarter any holder has the option to convert such holder's notes (and the Company is required to notify the trustee under the notes, and the holders of the notes, that this condition to conversion has been met). At any time on or after July 15, 2016, any holder has the option to convert such holder's notes into shares of Griffon common stock. Griffon has the intent and ability to settle the principal component of any conversion of notes in cash. 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 30, 2015 , aggregate dividends since the last conversion price adjustment of $0.08 per share would have resulted in an adjustment to the conversion ratio of approximately 0.48% . At both September 30, 2015 and 2014 , the 2017 Notes had a capital in excess of par component, net of tax, of $15,720 . The fair value of the 2017 Notes approximated $118,875 on September 30, 2015 based upon quoted market prices (level 1 inputs). These notes are classified as long term debt as Griffon has the intent and ability to refinance the principal amount of the notes, including with borrowings under the Credit Agreement. (d) In September 2015, Griffon entered into a $32,280 mortgage loan secured by four properties occupied by Griffon's subsidiaries, refinancing two existing real estate mortgages and providing new mortgages on two existing real estate properties. The loans mature in September 2025 , are collateralized by the specific properties financed and are guaranteed by Griffon. The loans bear interest at a rate of LIBOR plus 1.50% . (e) In December 2013, Griffon’s Employee Stock Ownership Plan (“ESOP”) entered into an agreement that refinanced the two existing ESOP loans into one new Term Loan in the amount of $21,098 (the "Agreement"). The Agreement also provided for a Line Note with $10,000 available to purchase shares of Griffon common stock in the open market. In July 2014, Griffon's ESOP entered into an amendment of the existing Agreement which provided an additional $10,000 Line Note available to purchase shares in the open market. During 2014, the Line Notes were combined with the Term Loan to form one new Term Loan. The Term Loan bears interest at LIBOR plus 2.38% or the lender’s prime rate, at Griffon’s option. The Term Loan requires quarterly principal payments of $551 , with a balloon payment of approximately $30,137 due at maturity on December 31, 2018. During 2014, 1,591,117 shares of Griffon common stock, for a total of $20,000 , or $12.57 per share, were purchased with proceeds from the Line Notes. The Term Loan is secured by shares purchased with the proceeds of the loan and with a lien on a specific amount of Griffon assets (which lien ranks pari passu with the lien granted on such assets under the Credit Agreement) and is guaranteed by Griffon. (f) In October 2006, CBP entered into a capital lease totaling $14,290 for real estate in Troy, Ohio. The lease matures in 2022 , bears interest at a fixed rate of 5.0% , is secured by a mortgage on the real estate and is guaranteed by Griffon. (g) In September 2015, Clopay Europe GMBH (“Clopay Europe”) entered into a EUR 5,000 ( $5,599 as of September 30, 2015) revolving credit facility and a EUR 15,000 ( $16,795 as of September 30, 2015) term loan. The term loan is payable in twelve quarterly installments of EUR 1,250 , bears interest at a fixed rate of 2.5% and matures in September 2018. The revolving facility matures in November 2016, but is renewable upon mutual agreement with the bank. The revolving credit facility accrues interest at EURIBOR plus 1.75% per annum ( 1.75% at September 30, 2015). The revolver and the term loan are both secured by substantially all of the assets of Clopay Europe and its subsidiaries. Griffon guarantees the revolving facility and term loan. The term loan had an outstanding balance of EUR 15 million and the revolver had no borrowings outstanding at September 30, 2015 . Clopay Europe is required to maintain a certain minimum equity to assets ratio and is subject to a maximum debt leverage ratio (defined as the ratio of total debt to EBITDA). Clopay do Brasil maintains lines of credit of approximately R $12,800 ( $3,222 as of September 30, 2015). Interest on borrowings accrues at a rate of Brazilian CDI plus 6.0% ( 20.13% at September 30, 2015 ). As of September 30, 2015 , there was approximately R $7,652 ( $1,926 as of September 30, 2015) borrowed under the lines borrowed under the lines. PPC guarantees the loan and lines. In November 2012, Garant G.P. (“Garant”) entered into a CAD 15,000 revolving credit facility. The facility accrues interest at LIBOR (USD) or the Bankers Acceptance Rate (CDN) plus 1.3% per annum ( 1.63% LIBOR USD and 2.03% Bankers Acceptance Rate CDN as of September 30, 2015 ). The revolving facility matures in October 2016. Garant is required to maintain a certain minimum equity. As of September 30, 2015 , there were CAD 7,481 ( $5,606 as of September 30, 2015) borrowed under the revolving credit facility with CAD 6,307 ( $4,726 as of September 30, 2015) available for borrowing. In December 2013 and May 2014, Northcote Holdings Pty Ltd entered into two unsecured term loans in the outstanding amounts of AUD 12,500 and AUD 20,000 . The AUD 12,500 term loan requires quarterly interest payments with principal due upon maturity in December 2016. The AUD 20,000 term loan requires quarterly principal payments of AUD 625 , with a balloon payment due upon maturity in May 2017. The loans accrue interest at Bank Bill Swap Bid Rate “BBSY” plus 2.8% per annum ( 4.98% at September 30, 2015 for each loan). As of September 30, 2015 , Griffon had an outstanding combined balance of AUD 31,874 ( $22,347 as of September 30, 2015) on the term loans, net of issuance costs. Subsidiaries of Northcote Holdings Pty Ltd also maintain two lines of credit of AUD 3,000 and AUD 5,000 ( $2,103 and $3,506 , respectively, as of September 30, 2015), which accrue interest at BBSY plus 2.25% per annum ( 4.43% at September 30, 2015 ) and 2.50% per annum ( 4.68% at September 30, 2015), respectively. As of September 30, 2015, there was AUD 2,000 ( $1,402 as of September 30, 2015) in outstanding borrowings under the lines. Griffon Corporation guarantees the term loans and the AUD 3,000 line of credit; the assets of a subsidiary of Northcote Holdings Pty Ltd secures the AUD 5,000 line of credit. (h) Other long-term debt primarily consists of capital leases. At September 30, 2015 , Griffon and its subsidiaries were in compliance with the terms and covenants of its credit and loan agreements.

EMPLOYEE BENEFIT PLANS

EMPLOYEE BENEFIT PLANS	12 Months Ended
	Sep. 30, 2015
Compensation and Retirement Disclosure [Abstract]
EMPLOYEE BENEFIT PLANS	EMPLOYEE BENEFIT PLANS Griffon offers defined contribution plans to most of its U.S. employees. In addition to employee contributions to the plans, Griffon makes contributions based upon various percentages of compensation and/or employee contributions, which were $7,988 in 2015 , $8,207 in 2014 and $6,950 in 2013 . The Company also provides healthcare and life insurance benefits for certain groups of retirees through several plans. For certain employees, the benefits are at fixed amounts per retiree and are partially contributory by the retiree. The post-retirement benefit obligation was $2,035 and $1,990 as of September 30, 2015 and 2014 . The accumulated other comprehensive income (loss) for these plans was $(97) and ($38) as of September 30, 2015 and 2014 , respectively, and the 2015 and 2014 benefit expense was $58 and $59 , respectively. It is the Company’s practice to fund these benefits as incurred. Griffon also has qualified and non-qualified defined benefit plans covering certain employees with benefits based on years of service and employee compensation. Over time, these amounts will be recognized as part of net periodic pension costs in the Consolidated Statements of Operations and Comprehensive Income (Loss). Griffon is responsible for overseeing the management of the investments of the qualified defined benefit plan and uses the services of an investment manager to manage these assets based on agreed upon risk profiles. The primary objective of the qualified defined benefit plan is to secure participant retirement benefits. As such, the key objective in this plan’s financial management is to promote stability and, to the extent appropriate, growth in the funded status. Financial objectives are established in conjunction with a review of current and projected plan financial requirements. The fair values of a majority of the plan assets were determined by the plans’ trustee using quoted market prices for identical instruments (level 1 inputs) as of September 30, 2015 and 2014 . The fair value of various other investments was determined by the plan’s trustee using direct observable market corroborated inputs, including quoted market prices for similar assets (level 2 inputs). There were no pension assets measured using level 3 inputs. Effective January 1, 2012, the Clopay Pension Plan merged with the Ames True Temper Inc. Pension Plan. The merged qualified defined benefit plan was named the Clopay Ames Pension Plan (the “Clopay AMES Plan”). The Clopay portion of the Clopay AMES Plan has been frozen to new entrants since December 2000. Certain employees who were part of the plan prior to December 2000 continued to accrue a service benefit through December 2010, at which time all plan participants stopped accruing service benefits. The AMES portion of the Clopay AMES Plan has been frozen to all new entrants since November 2009 and stopped accruing benefits in December 2009. The AMES supplemental executive retirement plan was frozen to new entrants and participants in the plan stopped accruing benefits in 2008. In 2014, the company contributed €1,300 (U.S. $1,776 ), which equaled the net balance sheet liability, in settlement of all remaining obligations for a non-U.S. pension liability. There were no gains or losses recorded for this settlement. In 2013, SG&A expenses included a $2,142 pension settlement loss resulting from the lump-sum buyout of certain participant’s balances in the Company’s defined benefit plan. The buyouts, funded by the pension plan, reduced the Company’s net pension liability at September 30, 2013 by $3,472 and increased Accumulated Other Comprehensive Income (Loss) by $3,649 at that date. Griffon uses judgment to establish the assumptions used in determining the future liability of the plan, as well as the investment returns on the plan assets. The expected return on assets assumption used for pension expense was developed through analysis of historical market returns, current market conditions and past experience of plan investments. The long-term rate of return assumption represents the expected average rate of earnings on the funds invested, or to be invested, to provide for the benefits included in the benefit obligations. The assumption is based on several factors including historical market index returns, the anticipated long-term asset allocation of plan assets and the historical return. The discount rate assumption is determined by developing a yield curve based on high quality bonds with maturities matching the plans’ expected benefit payment stream. The plans’ expected cash flows are then discounted by the resulting year-by-year spot rates. A 10% change in the discount rate, average wage increase or return on assets would not have a material effect on the financial statements of Griffon.

Griffon does not expect to make any contributions to the Defined Benefit plan in 2016 . The Clopay AMES Plan is covered by the Pension Protection Act of 2006. The Adjusted Funding Target Attainment Percent for the plan as of January 1, 2015 was 102.3% . Since the plan was in excess of the 80% funding threshold there were no plan restrictions. The expected level of 2016 catch up contributions is $0 . The following is a description of the valuation methodologies used for plan assets measured at fair value: Short-term investment funds – The fair value is determined using the Net Asset Value (“NAV”) provided by the administrator of the fund. The NAV is based on the value of the underlying assets owned by the fund, minus its liabilities, and then divided by the number of shares outstanding. The NAV is a quoted price in a market that is not active and is primarily classified as Level 2. These investments can be liquidated on demand. Government and agency securities – When quoted market prices are available in an active market, the investments are classified as Level 1. When quoted market prices are not available in an active market, the investments are classified as Level 2. Equity securities – The fair values reflect the closing price reported on a major market where the individual mutual fund securities are traded in equity securities. These investments are classified within Level 1 of the valuation hierarchy. Debt securities – The fair values are based on a compilation of primarily observable market information or a broker quote in a non-active market where the individual mutual fund securities are invested in debt securities. These investments are primarily classified within Level 2 of the valuation hierarchy. Commingled funds – The fair values are determined using NAV provided by the administrator of the fund. The NAV is based on the value of the underlying assets owned by the trust/entity, minus its liabilities, and then divided by the number of shares outstanding. These investments are generally classified within Level 2 of the valuation hierarchy and can be liquidated on demand. Interest in limited partnerships and hedge funds - One limited partnership investment is a private equity fund and the fair value is determined by the fund managers based on the estimated value of the various holdings of the fund portfolio. These investments are classified within Level 2 of the valuation hierarchy. The following table presents the fair values of Griffon’s pension and post-retirement plan assets by asset category: At September 30, 2015 Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total Cash and equivalents $ 1,370 $ — $ — $ 1,370 Short-term investment funds — — — — Government agency securities — — — — Debt instruments 14,291 — — 14,291 Equity securities 44,742 — — 44,742 Commingled funds — 78,490 — 78,490 Limited partnerships and hedge fund investments — 5,732 — 5,732 Total $ 60,403 $ 84,222 $ — $ 144,625 At September 30, 2014 Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total Cash and equivalents $ 2,912 $ — $ — $ 2,912 Short-term investment funds — — — — Government agency securities — — — — Debt instruments 29,447 — — 29,447 Equity securities 45,870 — — 45,870 Commingled funds — 72,722 — 72,722 Insurance contracts Limited partnerships and hedge fund investments — 4,015 — 4,015 Total $ 78,229 $ 76,737 $ — $ 154,966 Griffon has an ESOP that covers substantially all domestic employees. All U.S. employees of Griffon, who are not members of a collective bargaining unit, automatically become eligible to participate in the plan on the October 1 st following completion of one year of service. Securities are allocated to participants’ individual accounts based on the proportion of each participant’s aggregate compensation (not to exceed $265 for the plan year ended September 30, 2015 ), to the total of all participants’ compensation. Shares of the ESOP which have been allocated to employee accounts are charged to expense based on the fair value of the shares transferred and are treated as outstanding in determining earnings per share. Dividends paid on shares held by the ESOP are used to offset debt service on ESOP Loans. Dividends paid on shares held in participant accounts are utilized to allocate shares from the aggregate number of shares to be released, equal in value to those dividends, based on the closing price of Griffon common stock on the dividend payment date. Compensation expense under the ESOP was $3,400 in 2015 , $2,447 in 2014 and $2,015 in 2013 . The cost of the shares held by the ESOP and not yet allocated to employees is reported as a reduction of Shareholders’ Equity. The fair value of the unallocated ESOP shares as of September 30, 2015 and 2014 based on the closing stock price of Griffon’s stock was $47,907 and $37,372 , respectively. The ESOP shares were as follows: At September 30, 2015 2014 Allocated shares 2,479,776 2,406,941 Unallocated shares 3,037,831 3,281,095 5,517,607 5,688,036

Differences between the effective income tax rate applied to Income from continuing operations and U.S. Federal income statutory rate were as follows: For the Years Ended September 30, 2015 2014 2013 U.S. Federal income tax provision (benefit) rate 35.0 % (35.0 )% 35.0 % State and local taxes, net of Federal benefit 4.9 % 17.5 % 2.8 % Non-U.S. taxes (4.0 )% (35.8 )% 5.3 % Change in tax contingency reserves 0.3 % (36.0 )% (10.9 )% Repatriation of foreign earnings 0.9 % 4.7 % (8.3 )% U.S. Valuation allowance (1.1 )% 4.5 % 10.1 % Non-deductible/non-taxable items, net (0.7 )% (3.4 )% 11.6 % Research credits (0.5 )% (3.9 )% (7.4 )% Deferred tax impact of state rate change — % (4.5 )% 15.0 % Other 1.3 % (5.0 )% (0.6 )% Effective tax provision (benefit) rate 36.1 % (96.9 )% 52.6 % The tax effect of temporary differences that give rise to future deferred tax assets and liabilities are as follows: At September 30, 2015 2014 Deferred tax assets: Bad debt reserves $ 2,083 $ 2,639 Inventory reserves 7,482 7,578 Deferred compensation (equity compensation and defined benefit plans) 38,169 35,683 Compensation benefits 6,186 4,662 Insurance reserve 3,079 3,336 Restructuring reserve 122 911 Warranty reserve 2,288 2,286 Net operating loss 24,089 32,512 Tax credits 6,704 6,378 Other reserves and accruals 5,206 4,164 95,408 100,149 Valuation allowance (10,462 ) (15,649 ) Total deferred tax assets 84,946 84,500 Deferred tax liabilities: Deferred income (7,432 ) (11,091 ) Goodwill and intangibles (72,645 ) (72,086 ) Property, plant and equipment (35,382 ) (34,302 ) Interest (2,053 ) (3,582 ) Other (102 ) (927 ) Total deferred tax liabilities (117,614 ) (121,988 ) Net deferred tax liabilities $ (32,668 ) $ (37,488 ) The decrease in the valuation allowance of $5,187 is primarily the result of operational improvements and other business strategies that increase profitability in a foreign jurisdiction. The components of the net deferred tax liability, by balance sheet account, were as follows: At September 30, 2015 2014 Prepaid and other current assets $ 14,827 $ 13,982 Other assets 9,571 872 Current liabilities (3,793 ) (2 ) Other liabilities (54,409 ) (53,798 ) Assets of discontinued operations 1,136 1,458 Net deferred liability $ (32,668 ) $ (37,488 ) At both September 30, 2015 and 2014 , Griffon has not recorded deferred income taxes on the undistributed earnings of its non-U.S. subsidiaries because of management’s ability and intent to indefinitely reinvest such earnings outside the U.S. At September 30, 2015 , Griffon’s share of the undistributed earnings of the non-U.S. subsidiaries amounted to approximately $64,534 . It is not practicable to estimate the amount of deferred tax liability related to investments in these foreign subsidiaries. At September 30, 2015 and 2014 , Griffon had loss carryforwards for non-U.S. tax purposes of $68,591 and $78,692 , respectively. The non-U.S. loss carryforwards are available for carryforward indefinitely. At September 30, 2015 and 2014 , Griffon had state and local loss carryforwards of $7,882 and $7,905 , respectively, which expire in varying amounts through 2035 . At September 30, 2015, Griffon had no federal loss carryforwards. At September 30, 2014, Griffon had federal loss carryforwards of $11,036 which were available for carryforward through 2034. At September 30, 2015 and 2014 , Griffon had federal tax credit carryforwards of $6,223 and $6,087 , respectively, which expire beginning in 2017 . Griffon files U.S. Federal, state and local tax returns, as well as applicable returns in Germany, Canada, Brazil, Australia, Ireland and other non-U.S. jurisdictions. Griffon’s U.S. Federal income tax returns are no longer subject to income tax examination for years before 2011, the German income tax returns are no longer subject to income tax examination for years through 2010 and major U.S. state and other non-U.S. jurisdictions are no longer subject to income tax examinations for years before 2005. Various U.S. state and non-U.S. statutory tax audits are currently underway. The following is a roll forward of unrecognized tax benefits: Balance at September 30, 2013 $ 10,520 Additions based on tax positions related to the current year 848 Additions based on tax positions related to prior years 531 Reductions based on tax positions related to prior years (2,549 ) Lapse of Statutes (1,204 ) Settlements (240 ) Balance at September 30, 2014 7,906 Additions based on tax positions related to the current year 645 Reductions based on tax positions related to prior years (252 ) Lapse of Statutes (448 ) Balance at Balance at September 30, 2015 $ 7,851 If recognized, the amount of potential tax benefits that would impact Griffon’s effective tax rate is $4,579 . Griffon recognizes potential accrued interest and penalties related to unrecognized tax benefits in income tax expense. At September 30, 2015 and 2014 , the combined amount of accrued interest and penalties related to tax positions taken or to be taken on Griffon’s tax returns and recorded as part of the reserves for uncertain tax positions was $655 and $754 , respectively. Griffon cannot reasonably estimate the extent to which existing liabilities for uncertain tax positions may increase or decrease within the next twelve months as a result of the progression of ongoing tax audits or other events. Griffon believes that it has adequately provided for all open tax years by tax jurisdiction.

Stockholders' Equity Note [Abstract]
STOCKHOLDERS’ EQUITY AND EQUITY COMPENSATION	STOCKHOLDERS’ EQUITY AND EQUITY COMPENSATION During 2015 , 2014 and 2013, the Company declared and paid dividends totaling $0.16 per share, $0.12 per share and $0.10 per share, respectively. The Company currently intends to pay dividends each quarter; however, payment of dividends is determined by the Board of Directors at its discretion based on various factors, and no assurance can be provided as to the payment of future dividends. 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. On January 30, 2014, shareholders approved an amendment and restatement of the Incentive Plan (as amended, the “Incentive Plan”), which, among other things, added 1,200,000 shares to the Incentive Plan. 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 are 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 4,200,000 ( 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 September 30, 2015 , 420,206 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. Compensation expense for restricted stock and restricted stock units ("RSUs") is recognized ratably over the required service period based on the fair value of the grant, calculated as the number of shares (or RSUs) granted multiplied by the stock price on date of grant, and for performance shares (or performance RSUs), the likelihood of achieving the performance criteria. Compensation cost related to stock-based awards with graded vesting, generally over a period of three to four years , is recognized using the straight-line attribution method and recorded within Selling, general and administrative expenses. The following table summarizes the Company’s compensation expense relating to all stock-based incentive plans: For the Years Ended September 30, 2015 2014 2013 Pre-tax compensation expense $ 11,110 $ 11,473 $ 12,495 Tax benefit (4,000 ) (3,224 ) (3,068 ) Total stock-based compensation expense, net of tax $ 7,110 $ 8,249 $ 9,427 All stock options were fully vested at September 30, 2012.

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 accordingly conduct 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 Union Tools ® Products. Since December 2004, a customer of AMES has been named in various litigation matters relating to certain Union Tools products. The plaintiffs in those litigation matters have asserted causes of action against the customer of AMES 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 AMES under federal and state law, including common law fraud. At some point, likely once the litigation against the customer of AMES ends, the customer may seek indemnity (including recovery of its legal fees and costs) against AMES for an unspecified amount. Presently, AMES cannot estimate the amount of loss, if any, if the customer were to seek legal recourse against AMES. Union Fork and Hoe, Frankfort, NY site. The former Union Fork and Hoe property in Frankfort NY was acquired by Ames in 2006 as part of a larger acquisition, and has historic site contamination involving chlorinated solvents, petroleum hydrocarbons and metals. AMES has entered into an Order on Consent with the New York State Department of Environmental Conservation. While the Order is without admission or finding of liability or acknowledgment that there has been a release of hazardous substances at the site, AMES is required to perform a remedial investigation of certain portions of the property and to recommend a remediation option. At the conclusion of the remediation phase to the satisfaction of the DEC, the DEC will issue a Certificate of Completion. AMES has performed significant investigative and remedial activities in the last few years under work plans approved by the DEC, and the DEC recently approved the final remedial investigation report. AMES is now required to submit a Feasibility Study investigating four remedial options, and expects to do so by March 31, 2016. The DEC is expected to issue a Record of Decision approving the selection of a remedial alternative by July 31, 2016. Implementation of the selected remedial alternative is expected to occur in 2016 to 2017. AMES has a number of defenses to liability in this matter, including its rights under a Consent Judgment entered into between the DEC and a predecessor of AMES relating to the site. 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”), the Defense Criminal Investigative Service (“DCIS”), and the Department of Justice ("DOJ") 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 and the DOJ. No claim has been asserted against Griffon in connection with this matter, and Griffon is unaware of any material financial exposure in connection with the 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 a material adverse effect on Telephonics because of its reliance on government contracts. General legal Griffon is subject to various laws and regulations relating to the protection of the environment and is a party to legal proceedings arising in the ordinary course of business. 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.

DESCRIPTION OF BUSINESS AND S30

DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Sep. 30, 2015
Accounting Policies [Abstract]
Consolidation	Consolidation The consolidated financial statements include the accounts of Griffon and all subsidiaries. Intercompany accounts and transactions have been eliminated in consolidation. The results of operations of acquired businesses are included from the dates of acquisitions.
Earnings (Loss) per share	Earnings (Loss) per share Due to rounding, the sum of earnings per share of Continuing operations and Discontinued operations may not equal earnings per share of Net income.
Discontinued operations – Installation Services	Discontinued operations – Installation Services In 2008, as a result of the downturn in the residential housing market, Griffon exited substantially all operating activities of its Installation Services segment which sold, installed and serviced garage doors and openers, fireplaces, floor coverings, cabinetry and a range of related building products, primarily for the new residential housing market. Operating results of substantially all of this segment have been reported as discontinued operations in the Consolidated Statements of Operations and Comprehensive Income (Loss) for all periods presented; Installation Services is excluded from segment reporting.
Reclassifications	Reclassifications Certain amounts in prior years have been reclassified to conform to the current year presentation.
Use of estimates	Use of estimates 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, the valuation of assets and liabilities of discontinued operations, acquisition assumptions used 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.
Cash and equivalents	Cash and equivalents Griffon considers all highly liquid investments purchased with an initial maturity of three months or less to be cash equivalents. Cash equivalents primarily consist of overnight commercial paper, highly-rated liquid money market funds backed by U.S. Treasury securities and U.S. Agency securities, as well as insured bank deposits. Griffon had cash in non-U.S. bank accounts of approximately $31,700 and $34,500 at September 30, 2015 and 2014 , respectively. Substantially all U.S. cash and equivalents are in excess of FDIC insured limits. Griffon regularly evaluates the financial stability of all institutions and funds that hold its cash and equivalents.
Fair value of financial instruments	Fair value of financial instruments 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 value hierarchy, as outlined in the applicable accounting guidance, establishes a fair value hierarchy that requires the Company to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. A financial instrument’s categorization within the hierarchy is based on the lowest level of input that is significant to the fair value measurement. The accounting guidance establishes three levels of inputs that may be used to measure fair value, as follows: • Level 1 inputs are measured and recorded at fair value based upon quoted prices in active markets for identical assets. • Level 2 inputs include inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices in active markets for similar assets and liabilities, quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of assets or liabilities. • Level 3 inputs are unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions. The fair values of Griffon’s 2022 senior notes and 2017 4% convertible notes approximated $570,000 and $118,875 , respectively, on September 30, 2015 . Fair values were based upon quoted market prices (level 1 inputs). Insurance contracts with a value of $2,942 at September 30, 2015 are measured and recorded at fair value based upon quoted prices in active markets for similar assets (level 2 inputs) and are included in Other current assets on the consolidated balance sheet. Items Measured at Fair Value on a Recurring Basis At September 30, 2015, trading securities, measured at fair value based on quoted prices in active markets for similar assets (level 2 inputs), with a fair value of $1,374 ( $1,000 cost basis) were included in Prepaid and other current assets on the Consolidated Balance Sheets. During the current year, the Company settled all outstanding available-for-sale securities with proceeds totaling $8,891 and recognized a gain of $489 in Other income, and accordingly, a gain of $870 , net of tax, on available-for-sale securities was reclassified out of Accumulated other comprehensive income (loss) ("AOCI"). At September 30, 2014, available-for-sale securities, measured at fair value based on quoted prices in active markets for the underlying assets (level 1 inputs), and trading securities, measured at fair value based on quoted prices in active markets for similar assets (level 2 inputs), with values of $9,770 ( $8,400 cost basis) and $1,274 ( $1,000 cost basis), respectively, are included in Prepaid and other current assets on the Consolidated Balance Sheets. Unrealized gains and losses, net of deferred taxes, on available-for-sale securities are included in our Consolidated Balance Sheets as a component of AOCI. Realized and unrealized gains and losses on trading securities and realized gains and losses on available-for-sale securities are included in Other income in the Consolidated Statements of Operations and Comprehensive Income (Loss). In the normal course of business, Griffon’s operations are exposed to the effect of changes in foreign currency exchange rates. To manage these risks, Griffon may enter into various derivative contracts such as foreign currency exchange contracts, including forwards and options. During 2015 and 2014, Griffon entered into several such contracts in order to lock into a foreign currency rate for planned settlements of trade and inter-company liabilities payable in USD. At September 30, 2015 and 2014, Griffon had $25,531 and $4,975 of Australian dollar contracts at a weighted average rate of $1.43 and $1.14 , which qualified for hedge accounting. At inception, these hedges were all deemed effective as cash flow hedges with gains and losses related to changes in fair value deferred and recorded in Other comprehensive income (loss) and Prepaid and other current assets, or Accrued liabilities, until settlement. Upon settlement, gains and losses were recognized in the Consolidated Statements of Operations and Comprehensive Income (Loss) in Cost of goods and services. AOCI included deferred gains of $1,049 ( $682 , net of tax) and $386 ( $252 , net of tax) at September 30, 2015 and 2014, respectively. A gain of $1,223 was recorded in COGS during the year ended September 30, 2015 for settled contracts and no contracts settled during the year ended September 30, 2014. At September 30, 2015 , Griffon had $6,500 of Canadian dollar contracts at a weighted average rate of $1.33 . As of September 30, 2014, Griffon had $3,197 of Australian dollar contracts at a weighted average rate of $1.14 . These contracts, which protect both Canadian and Australian operations from currency fluctuations for U.S. dollar based purchases, do not qualify for hedge accounting and a fair value loss of $274 and gain of $141 were recorded in Other assets and to Other income for the outstanding contracts, based on similar contract values (level 2 inputs), for the years ended September 30, 2015 and 2014, respectively. All contracts expire in 30 to 360 days . Pension plan assets with a fair value of $144,625 at September 30, 2015 , are measured and recorded at fair value based upon quoted prices in active markets for identical assets (level 1 inputs) and quoted market prices for similar assets (level 2 inputs).
Non-U.S. currency translation	Non-U.S. currency translation Assets and liabilities of non-U.S. subsidiaries, where the functional currency is not the U.S. dollar, have been translated at year-end exchange rates and profit and loss accounts have been translated using weighted average exchange rates. Adjustments resulting from currency translation have been recorded in the equity section of the balance sheet in AOCI as cumulative translation adjustments. Cumulative translation adjustments were a loss of $60,178 and $3,820 at September 30, 2015 and 2014 , respectively. Assets and liabilities of an entity that are denominated in currencies other than that entity’s functional currency are remeasured into the functional currency using period end exchange rates, or historical rates where applicable to certain balances. Gains and losses arising on remeasurements are recorded within the Consolidated Statement of Operations and Comprehensive Income (Loss) as a component of Other income (expense).
Revenue recognition	Revenue recognition Revenue is recognized when the following circumstances are satisfied: a) persuasive evidence of an arrangement exists, b) delivery has occurred, title has transferred or services are rendered, c) price is fixed and determinable and d) collectability is reasonably assured. Goods are sold on terms that transfer title and risk of loss at a specified location. Revenue recognition from product sales occurs when all factors are met, including transfer of title and risk of loss, which occurs either upon shipment or upon receipt by customers at the location specified in the terms of sale. Other than standard product warranty provisions, sales arrangements provide for no other significant post-shipment obligations. From time to time and for certain customers, rebates and other sales incentives, promotional allowances or discounts are offered, typically related to customer purchase volumes, all of which are fixed or determinable and are classified as a reduction of revenue and recorded at the time of sale. Griffon provides for sales returns allowances based upon historical returns experience. Telephonics earns a substantial portion of its revenue as either a prime or subcontractor from contract awards with the U.S. Government, as well as non-U.S. governments and other commercial customers. These formal contracts are typically long-term in nature, usually greater than one year . Revenue and profits from these long-term fixed price contracts are recognized under the percentage-of-completion method of accounting. Revenue and profits on fixed-price contracts that contain engineering as well as production requirements are recorded based on the ratio of total actual incurred costs to date to the total estimated costs for each contract (cost-to-cost method). Using the cost-to-cost method, revenue is recorded at amounts equal to the ratio of actual cumulative costs incurred divided by total estimated costs at completion, multiplied by the total estimated contract revenue, less the cumulative revenue recognized in prior periods. The profit recorded on a contract using this method is equal to the current estimated total profit margin multiplied by the cumulative revenue recognized, less the amount of cumulative profit previously recorded for the contract in prior periods. As this method relies on the substantial use of estimates, these projections may be revised throughout the life of a contract. Components of this formula and ratio that may be estimated include gross profit margin and total costs at completion. The cost performance and estimates to complete on long-term contracts are reviewed, at a minimum, on a quarterly basis, as well as when information becomes available that would necessitate a review of the current estimate. Adjustments to estimates for a contract’s estimated costs at completion and estimated profit or loss often are required as experience is gained, and as more information is obtained, even though the scope of work required under the contract may or may not change, or if contract modifications occur. The impact of such adjustments or changes to estimates is made on a cumulative basis in the period when such information has become known. In 2015, 2014 and 2013, income from operations included net favorable/(unfavorable) catch-up adjustments approximating $(400) , $(400) and $3,400 , respectively. Gross profit is affected by a variety of factors, including the mix of products, systems and services, production efficiencies, price competition and general economic conditions. Revenue and profits on cost-reimbursable type contracts are recognized as allowable costs, and are incurred on the contract at an amount equal to the allowable costs plus the estimated profit on those costs. The estimated profit on a cost-reimbursable contract may be fixed or variable based on the contractual fee arrangement. Incentive and award fees on these contracts are recorded as revenue when the criteria under which they are earned are reasonably assured of being met and can be estimated. For contracts in which anticipated total costs exceed the total expected revenue, an estimated loss is recognized in the period when identifiable. A provision for the entire amount of the estimated loss is recorded on a cumulative basis. The estimated remaining costs to complete loss contracts as of September 30, 2015 was $10,600 and is recorded as a reduction to gross margin on the Consolidated Statements of Operations and Comprehensive Income (Loss). This loss had an immaterial impact on Griffon's Consolidated Financial Statements. Amounts representing contract change orders or claims are included in revenue only when they can be reliably estimated and their realization is probable, and are determined on a percentage-of-completion basis measured by the cost-to-cost method. From time to time, Telephonics may combine contracts if they are negotiated together, have specific requirements to combine, or are otherwise closely related. Contracts are segmented based on customer requirements.
Accounts receivable, allowance for doubtful accounts and concentrations of credit risk	Accounts receivable, allowance for doubtful accounts and concentrations of credit risk Accounts receivable is composed principally of trade accounts receivable that arise from the sale of goods or services on account, and is stated at historical cost. A substantial portion of Griffon’s trade receivables are from customers of HBP, of which the largest customer is Home Depot, whose financial condition is dependent on the construction and related retail sectors of the economy. In addition, a significant portion of Griffon’s trade receivables are from one PPC customer, P&G, whose financial condition is dependent on the consumer products and related sectors of the economy. As a percentage of consolidated accounts receivable, U.S. Government related programs were 13% , P&G was 8% and Home Depot was 10% . Griffon performs continuing evaluations of the financial condition of its customers, and although Griffon generally does not require collateral, letters of credit may be required from customers in certain circumstances. Trade receivables are recorded at the stated amount, less allowance for doubtful accounts and, when appropriate, for customer program reserves and cash discounts. The allowance represents estimated uncollectible receivables associated with potential customer defaults on contractual obligations (usually due to customers’ potential insolvency). The allowance for doubtful accounts includes amounts for certain customers where a risk of default has been specifically identified, as well as an amount for customer defaults based on a formula when it is determined the risk of some default is probable and estimable, but cannot yet be associated with specific customers. The provision related to the allowance for doubtful accounts is recorded in Selling, general and administrative ("SG&A") expenses. The Company writes-off accounts receivable when they are deemed to be uncollectible.
Contract costs and recognized income not yet billed	Contract costs and recognized income not yet billed Contract costs and recognized income not yet billed consists of amounts accounted for under the percentage of completion method of accounting, recoverable costs and accrued profit that cannot yet be invoiced under the terms of certain long-term contracts. Amounts will be invoiced when applicable contract terms, such as the achievement of specified milestones or product delivery, are met.
Inventories	Inventories Inventories, stated at the lower of cost (first-in, first-out or average) or market, include material, labor and manufacturing overhead costs. Griffon’s businesses typically do not require inventory that is susceptible to becoming obsolete or dated. In general, Telephonics sells products in connection with programs authorized and approved under contracts awarded by the U.S. Government or agencies thereof and in accordance with customer specifications. PPC primarily produces fabricated materials used by customers in the production of their products and these materials are produced against orders from those customers. HBP produces doors and non-powered lawn and garden tools in response to orders from customers of retailers and dealers or based on expected orders, as applicable.
Property, plant and equipment	Property, plant and equipment Property, plant and equipment includes the historical cost of land, buildings, equipment and significant improvements to existing plant and equipment or, in the case of acquisitions, a fair market value appraisal of such assets completed at the time of acquisition. Expenditures for maintenance, repairs and minor renewals are expensed as incurred. When property or equipment is sold or otherwise disposed of, the related cost and accumulated depreciation is removed from the respective accounts and the gain or loss is recognized. No event or indicator of impairment occurred during the three years ended September 30, 2015, which would require additional impairment testing of property, plant and equipment. Depreciation expense, which includes amortization of assets under capital leases, was $62,144 , $59,488 and $62,911 for the years ended September 30, 2015 , 2014 and 2013 , respectively, and was calculated on a straight-line basis over the estimated useful lives of the assets. Depreciation included in SG&A expenses was $13,009 , $10,815 and $12,733 for the years ended September 30, 2015, 2014 and 2013. The remaining components of depreciation, attributable to manufacturing operations, are included in Cost of goods and services. Estimated useful lives for property, plant and equipment are as follows: buildings and building improvements, 25 to 40 years ; machinery and equipment, 2 to 15 years and leasehold improvements, over the term of the lease or life of the improvement, whichever is shorter.
Goodwill and indefinite-lived intangibles	Goodwill and indefinite-lived intangibles Goodwill is the excess of the acquisition cost of a business over the fair value of the identifiable net assets acquired. Goodwill is not amortized, but is subject to an annual impairment test unless during an interim period, impairment indicators such as a significant change in the business climate exist. Griffon performed its annual impairment testing of goodwill as of September 30, 2015 . The performance of the test involves a two-step process. The first step involves comparing the fair value of Griffon’s reporting units with the reporting unit’s carrying amount, including goodwill. Griffon generally determines the fair value of its reporting units using the income approach methodology of valuation that includes the present value of expected future cash flows. This method uses market assumptions specific to Griffon’s reporting units. If the carrying amount of a reporting unit exceeds the reporting unit’s fair value, Griffon performs the second step of the goodwill impairment test to determine the amount of impairment loss. The second step compares the implied fair value of the reporting unit’s goodwill with the carrying amount of that goodwill. Griffon defines its reporting units as its three reportable segments: HBP, Telephonics and PPC. HBP consists of two components, AMES and CBP, which due to their similar economic characteristics, are aggregated into one reporting unit for goodwill testing. Griffon used 5 year projections and a 3.0% terminal value to which discount rates between 9% and 10% were applied to calculate each unit’s fair value. To substantiate fair values derived from the income approach methodology of valuation, the implied fair value was reconciled to Griffon’s market capitalization, the results of which supported the implied fair values. Any changes in key assumptions or management judgment with respect to a reporting unit or its prospects, which may result from a decline in Griffon’s stock price, a change in market conditions, market trends, interest rates or other factors outside Griffon’s control, or significant underperformance relative to historical or project future operating results, could result in a significantly different estimate of the fair value of the reporting units, which could result in a future impairment charge (level 3 inputs). Based upon the results of the annual impairment review, it was determined that the fair value of each reporting unit substantially exceeded the carrying value of the assets, as performed under step one, and no impairment existed. Similar to goodwill, Griffon tests indefinite-lived intangible assets at least annually and when indicators of impairment exist. Griffon uses a discounted cash flow method to calculate and compare the fair value of the intangible to its book value. This method uses market assumptions specific to Griffon’s reporting units, which are reasonable and supportable. If the fair value is less than the book value of the indefinite-lived intangibles, an impairment charge would be recognized.
Definite-lived long-lived assets	Definite-lived long-lived assets Amortizable intangible assets are carried at cost less accumulated amortization. For financial reporting purposes, definite-lived intangible assets are amortized on a straight-line basis over their useful lives, generally eight to twenty-five years . Long-lived assets and certain identifiable intangible assets to be held and used are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Determination of recoverability is based on an estimate of undiscounted future cash flows resulting from the use of the asset and its eventual disposition.
Income taxes	Income taxes Income taxes are accounted for under the liability method. Deferred taxes reflect the tax consequences on future years of differences between the tax basis of assets and liabilities and their financial reporting amounts. The carrying value of Griffon’s deferred tax assets is dependent upon Griffon’s ability to generate sufficient future taxable income in certain tax jurisdictions. Should Griffon determine that it is more likely than not that some portion of the deferred tax assets will not be realized, a valuation allowance against the deferred tax assets would be established in the period such determination was made. Griffon provides for uncertain tax positions and any related interest and penalties based upon Management’s assessment of whether a tax benefit is more likely than not of being sustained upon examination by tax authorities. At September 30, 2015 Griffon believes that it has appropriately accounted for all unrecognized tax benefits. As of September 30, 2015 , 2014 and 2013 , Griffon has recorded unrecognized tax benefits in the amount of $7,851 , $7,906 and $10,520 , respectively. Accrued interest and penalties related to income tax matters are recorded in the provision for income taxes.
Research and development costs, shipping and handling costs and advertising costs	Research and development costs, shipping and handling costs and advertising costs Research and development costs not recoverable under contractual arrangements are charged to SG&A expense as incurred and amounted to $25,600 , $23,400 and $22,400 in 2015 , 2014 and 2013 , respectively. SG&A expenses include shipping and handling costs of $40,800 in 2015 , $42,400 in 2014 and $39,600 in 2013 and advertising costs, which are expensed as incurred, of $24,000 in 2015 , $24,000 in 2014 and $23,000 in 2013 .
Risk, retention and insurance	Risk, retention and insurance Griffon’s property and casualty insurance programs contain various deductibles that, based on Griffon’s experience, are reasonable and customary for a company of its size and risk profile. Griffon generally maintains deductibles for claims and liabilities related primarily to workers’ compensation, general, product and automobile liability as well as property damage and business interruption losses resulting from certain events. Griffon does not consider any of the deductibles to represent a material risk to Griffon. Griffon accrues for claim exposures that are probable of occurrence and can be reasonably estimated. Insurance is maintained to transfer risk beyond the level of self-retention and provides protection on both an individual claim and annual aggregate basis.
Pension benefits	Pension benefits Griffon sponsors defined and supplemental benefit pension plans for certain retired employees. Annual amounts relating to these plans are recorded based on actuarial projections, which include various actuarial assumptions, including discount rates, assumed rates of return, compensation increases and turnover rates. Actuarial assumptions used to determine pension liabilities, assets and expense are reviewed annually and modified based on current economic conditions and trends. The expected return on plan assets is determined based on the nature of the plan's investments and expectations for long-term rates of return. The discount rate used to measure obligations is based on a corporate bond spot-rate yield curve that matches projected future benefit payments, with the appropriate spot rate applicable to the timing of the projected future benefit payments. Assumptions used in determining Griffon’s obligations under the defined benefit pension plans are believed to be reasonable, based on experience and advice from independent actuaries; however, differences in actual experience or changes in assumptions may materially impact Griffon’s financial position or results of operations. All of the defined benefit plans are frozen and have ceased accruing benefits.
Newly issued but not yet effective accounting pronouncements	Newly issued but not yet effective accounting pronouncements In May 2014, the FASB issued guidance on revenue from contracts with customers. The underlying principle is that an entity will recognize revenue to depict the transfer of goods or services to customers at an amount that the entity expects to be entitled to in exchange for those goods or services. The guidance provides a five-step analysis of transactions to determine when and how revenue is recognized. Other major provisions include capitalization of certain contract costs, consideration of time value of money in the transaction price, and allowing estimates of variable consideration to be recognized before contingencies are resolved, in certain circumstances. The guidance also requires enhanced disclosures regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from an entity's contracts with customers. This guidance permits the use of either the retrospective or cumulative effect transition method and is effective for the Company beginning in 2019; early adoption is permitted beginning in 2018. We have not yet selected a transition method and are currently evaluating the impact of the guidance on the Company's financial condition, results of operations and related disclosures. In August 2014, the FASB issued guidance on management's responsibility in evaluating whether there is substantial doubt about a company's ability to continue as a going concern and related footnote disclosures. Management will be required to evaluate, at each reporting period, whether there are conditions or events that raise substantial doubt about a company's ability to continue as a going concern within one year from the date the financial statements are issued. This guidance is effective prospectively for annual and interim reporting period beginning in 2017; implementation of this guidance is not expected to have a material effect on the Company’s financial condition or results of operations.
Recently issued effective accounting pronouncements	Recently issued effective accounting pronouncements In July 2013, the FASB issued new accounting guidance requiring an unrecognized tax benefit to be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss or tax credit carryforward, except for instances when the carryforward is not available to settle any additional income taxes and an entity does not intend to use the deferred tax benefit for these purposes. In these circumstances, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. This guidance was effective for fiscal for fiscal years beginning after December 15, 2013, and accordingly, the Company adopted this guidance effective October 1, 2014. Adoption of this standard did not have a significant impact on the Company's consolidated financial statements. In April 2014, the FASB issued guidance changing the requirements for reporting discontinued operations where a disposal of a component of an entity or group of components of an entity is required to be reported in discontinued operations if the disposal represents a strategic shift that has (or will have) a major effect on an entity's operations and financial results when either classified as held for sale, or disposed of by sale or otherwise disposed. The amendment also requires enhanced disclosures about the discontinued operation and disclosure information for other significant dispositions. This guidance was effective for the Company beginning in 2015. Adoption of this standard did not have a significant impact on the Company's consolidated financial statements. In April 2015, the FASB issued guidance on simplifying the presentation of debt issuance costs. This guidance required debt issuance costs on the balance sheet to be presented as a direct deduction from the carrying amount of a related debt liability, similar to debt discounts. The Company early adopted this guidance in March 2015 and applied it retrospectively for all periods presented in the financial statements. Adoption of this standard did not have a significant impact on the Company's consolidated financial statements. The Company has implemented all new accounting pronouncements that are in effect and that may impact its financial statements and does not believe that there are any other new accounting pronouncements that have been issued that might have a material impact on its financial position or results of operations.

Proceeds from the Senior Notes were used to redeem $550,000 of 7.125% senior notes due 2018, to pay a call and tender offer premium of $31,530 and to make interest payments of $16,716 , with the balance used to pay a portion of the related transaction fees and expenses. In connection with the issuance of the Senior Notes, all obligations under the $550,000 of 7.125% senior notes due in 2018 were discharged. The Senior Notes are senior unsecured obligations of Griffon guaranteed by certain domestic subsidiaries, and subject to certain covenants, limitations and restrictions. On June 18, 2014, Griffon exchanged all of the Senior Notes for substantially identical Senior Notes registered under the Securities Act of 1933 via an exchange offer. The fair value of Senior Notes approximated $570,000 on September 30, 2014 based upon quoted market prices (level 1 inputs). In connection with these transactions, Griffon capitalized $10,313 of underwriting fees and other expenses incurred related to the issuance and exchange of the Senior Notes, which will amortize over the term of such notes. Griffon recognized a loss on the early extinguishment of debt on the 7.125% senior notes aggregating $38,890 , comprised of the $31,530 tender offer premium, the write-off of $6,574 of remaining deferred financing fees and $786 of prepaid interest on defeased notes. (b) On March 13, 2015, Griffon amended its Revolving Credit Facility (“Credit Agreement”) to increase the credit facility from $225,000 to $250,000 , extend its maturity from March 28, 2019 to March 13, 2020, and modify certain other provisions of the facility. The facility includes a letter sub-facility with a limit of $50,000 (decreased from $60,000 ), and a multi-currency sub-facility of $50,000 . The Credit Agreement provides for same day borrowings of base rate loans in lieu of a swing line sub-facility. Borrowings under the Credit Agreement may be repaid and re-borrowed at any time, subject to final maturity of the facility, or the occurrence or event of default under the Credit Agreement. Interest is payable on borrowings at either a LIBOR or base rate benchmark rate, in each case without a floor, plus an applicable margin, which adjusts based on financial performance. Current margins are 1.00% for base rate loans and 2.00% for LIBOR loans. 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 negative covenants place limits on Griffon's ability to, among other things, incur indebtedness, incur liens, and make restricted payments and investments. The Credit Agreement also has a minimum liquidity covenant that requires cash and available borrowings under the Credit Agreement in the aggregate to equal or exceed $100 million during the six month period prior to maturity of the 2017 Notes (which mature on January 15, 2017); such covenant will no longer apply after payment in full of the 2017 Notes. Borrowings under the Credit Agreement are guaranteed by Griffon’s material domestic subsidiaries and are secured, on a first priority basis, by substantially all domestic assets of the Company and the guarantors and a pledge of not greater than 65% of the equity interest in each of Griffon’s material, first-tier foreign subsidiaries (except that a lien on the assets of Griffon’s material domestic subsidiaries securing a limited amount of the debt under the credit agreement relating to Griffon's Employee Stock Ownership Plan ranks pari passu with the lien granted on such assets under the Credit Agreement; see footnote (d) below). At September 30, 2015 , outstanding borrowings and standby letters of credit were $35,000 and $16,938 , respectively, under the Credit Agreement; $198,062 was available for borrowing at that date. (c) On December 21, 2009, Griffon issued $100,000 principal of 4% convertible subordinated notes due 2017 (the “2017 Notes”). The current conversion rate of the 2017 Notes is 69.3811 shares of Griffon’s common stock per $1 principal amount of notes, corresponding to a conversion price of $14.41 per share. Prior to July 15, 2016, if for at least 20 trading days out of the last 30 trading days during any fiscal quarter the closing price of Griffon's common stock is 130% or greater than the conversion price on each such trading day, then at any time during the immediately subsequent fiscal quarter any holder has the option to convert such holder's notes (and the Company is required to notify the trustee under the notes, and the holders of the notes, that this condition to conversion has been met). At any time on or after July 15, 2016, any holder has the option to convert such holder's notes into shares of Griffon common stock. Griffon has the intent and ability to settle the principal component of any conversion of notes in cash. 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 30, 2015 , aggregate dividends since the last conversion price adjustment of $0.08 per share would have resulted in an adjustment to the conversion ratio of approximately 0.48% . At both September 30, 2015 and 2014 , the 2017 Notes had a capital in excess of par component, net of tax, of $15,720 . The fair value of the 2017 Notes approximated $118,875 on September 30, 2015 based upon quoted market prices (level 1 inputs).

In July 2014, Griffon's ESOP entered into an amendment of the existing Agreement which provided an additional $10,000 Line Note available to purchase shares in the open market. During 2014, the Line Notes were combined with the Term Loan to form one new Term Loan. The Term Loan bears interest at LIBOR plus 2.38% or the lender’s prime rate, at Griffon’s option. The Term Loan requires quarterly principal payments of $551 , with a balloon payment of approximately $30,137 due at maturity on December 31, 2018. During 2014, 1,591,117 shares of Griffon common stock, for a total of $20,000 , or $12.57 per share, were purchased with proceeds from the Line Notes.

(a) On February 27, 2014, in an unregistered offering through a private placement under Rule 144A, Griffon issued, at par, $600,000 of 5.25% Senior Notes due in 2022 (“Senior Notes”); interest is payable semi-annually on March 1 and September 1. Proceeds from the Senior Notes were used to redeem $550,000 of 7.125% senior notes due 2018, to pay a call and tender offer premium of $31,530 and to make interest payments of $16,716 , with the balance used to pay a portion of the related transaction fees and expenses. In connection with the issuance of the Senior Notes, all obligations under the $550,000 of 7.125% senior notes due in 2018 were discharged. The Senior Notes are senior unsecured obligations of Griffon guaranteed by certain domestic subsidiaries, and subject to certain covenants, limitations and restrictions. On June 18, 2014, Griffon exchanged all of the Senior Notes for substantially identical Senior Notes registered under the Securities Act of 1933 via an exchange offer. The fair value of Senior Notes approximated $570,000 on September 30, 2014 based upon quoted market prices (level 1 inputs). In connection with these transactions, Griffon capitalized $10,313 of underwriting fees and other expenses incurred related to the issuance and exchange of the Senior Notes, which will amortize over the term of such notes. Griffon recognized a loss on the early extinguishment of debt on the 7.125% senior notes aggregating $38,890 , comprised of the $31,530 tender offer premium, the write-off of $6,574 of remaining deferred financing fees and $786 of prepaid interest on defeased notes.

Current margins are 1.00% for base rate loans and 2.00% for LIBOR loans. 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 negative covenants place limits on Griffon's ability to, among other things, incur indebtedness, incur liens, and make restricted payments and investments. The Credit Agreement also has a minimum liquidity covenant that requires cash and available borrowings under the Credit Agreement in the aggregate to equal or exceed $100 million during the six month period prior to maturity of the 2017 Notes (which mature on January 15, 2017); such covenant will no longer apply after payment in full of the 2017 Notes.

[2]	In September 2015, Clopay Europe GMBH (“Clopay Europe”) entered into a EUR 5,000 ($5,599 as of September 30, 2015) revolving credit facility and a EUR 15,000 ($16,795 as of September 30, 2015) term loan. The term loan is payable in twelve quarterly installments of EUR 1,250, bears interest at a fixed rate of 2.5% and matures in September 2018. The revolving facility matures in November 2016, but is renewable upon mutual agreement with the bank. The revolving credit facility accrues interest at EURIBOR plus 1.75% per annum (1.75% at September 30, 2015). The revolver and the term loan are both secured by substantially all of the assets of Clopay Europe and its subsidiaries. Griffon guarantees the revolving facility and term loan. The term loan had an outstanding balance of EUR 15 million and the revolver had no borrowings outstanding at September 30, 2015. Clopay Europe is required to maintain a certain minimum equity to assets ratio and is subject to a maximum debt leverage ratio (defined as the ratio of total debt to EBITDA). Clopay do Brasil maintains lines of credit of approximately R$12,800 ($3,222 as of September 30, 2015). Interest on borrowings accrues at a rate of Brazilian CDI plus 6.0% (20.13% at September 30, 2015). As of September 30, 2015, there was approximately R$7,652 ($1,926 as of September 30, 2015) borrowed under the lines borrowed under the lines. PPC guarantees the loan and lines.In November 2012, Garant G.P. (“Garant”) entered into a CAD 15,000 revolving credit facility. The facility accrues interest at LIBOR (USD) or the Bankers Acceptance Rate (CDN) plus 1.3% per annum (1.63% LIBOR USD and 2.03% Bankers Acceptance Rate CDN as of September 30, 2015). The revolving facility matures in October 2016. Garant is required to maintain a certain minimum equity. As of September 30, 2015, there were CAD 7,481($5,606 as of September 30, 2015) borrowed under the revolving credit facility with CAD 6,307 ($4,726 as of September 30, 2015) available for borrowin
[3]	On February 27, 2014, in an unregistered offering through a private placement under Rule 144A, Griffon issued, at par, $600,000 of 5.25% Senior Notes due in 2022 (“Senior Notes”); interest is payable semi-annually on March 1 and September 1. Proceeds from the Senior Notes were used to redeem $550,000 of 7.125% senior notes due 2018, to pay a call and tender offer premium of $31,530 and to make interest payments of $16,716, with the balance used to pay a portion of the related transaction fees and expenses. In connection with the issuance of the Senior Notes, all obligations under the $550,000 of 7.125% senior notes due in 2018 were discharged. The Senior Notes are senior unsecured obligations of Griffon guaranteed by certain domestic subsidiaries, and subject to certain covenants, limitations and restrictions. On June 18, 2014, Griffon exchanged all of the Senior Notes for substantially identical Senior Notes registered under the Securities Act of 1933 via an exchange offer. The fair value of Senior Notes approximated $570,000 on September 30, 2014 based upon quoted market prices (level 1 inputs).In connection with these transactions, Griffon capitalized $10,313 of underwriting fees and other expenses incurred related to the issuance and exchange of the Senior Notes, which will amortize over the term of such notes. Griffon recognized a loss on the early extinguishment of debt on the 7.125% senior notes aggregating $38,890, comprised of the $31,530 tender offer premium, the write-off of $6,574 of remaining deferred financing fees and $786 of prepaid interest on defeased notes. (b)On March 13, 2015, Griffon amended its Revolving Credit Facility (“Credit Agreement”) to increase the credit facility from$225,000 to $250,000, extend its maturity from March 28, 2019 to March 13, 2020, and modify certain other provisions of the facility. The facility includes a letter sub-facility with a limit of $50,000 (decreased from $60,000), and a multi-currency sub-facility of $50,000. The Credit Agreement provides for same day borrowings of base rate loans in lieu of a swing line sub-facility. Borrowings under the Credit Agreement may be repaid and re-borrowed at any time, subject to final maturity of the facility, or the occurrence or event of default under the Credit Agreement. Interest is payable on borrowings at either a LIBOR or base rate benchmark rate, in each case without a floor, plus an applicable margin, which adjusts based on financial performance. Current margins are 1.00% for base rate loans and 2.00% for LIBOR loans. 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 negative covenants place limits on Griffon's ability to, among other things, incur indebtedness, incur liens, and make restricted payments and investments. The Credit Agreement also has a minimum liquidity covenant that requires cash and available borrowings under the Credit Agreement in the aggregate to equal or exceed $100 million during the six month period prior to maturity of the 2017 Notes (which mature on January 15, 2017); such covenant will no longer apply after payment in full of the 2017 Notes. Borrowings under the Credit Agreement are guaranteed by Griffon’s material domestic subsidiaries and are secured, on a first priority basis, by substantially all domestic assets of the Company and the guarantors and a pledge of not greater than 65% of the equity interest in each of Griffon’s material, first-tier foreign subsidiaries (except that a lien on the assets of Griffon’s material domestic subsidiaries securing a limited amount of the debt under the credit agreement relating to Griffon's Employee Stock Ownership Plan ranks pari passu with the lien granted on such assets under the Credit Agreement; see footnote (d) below). At September 30, 2015, outstanding borrowings and standby letters of credit were $35,000 and $16,938, respectively, under the Credit Agreement; $198,062 was available for borrowing at that date
[4]	On December 21, 2009, Griffon issued $100,000 principal of 4% convertible subordinated notes due 2017 (the “2017 Notes”). The current conversion rate of the 2017 Notes is 69.3811 shares of Griffon’s common stock per $1 principal amount of notes, corresponding to a conversion price of $14.41 per share. Prior to July 15, 2016, if for at least 20 trading days out of the last 30 trading days during any fiscal quarter the closing price of Griffon's common stock is 130% or greater than the conversion price on each such trading day, then at any time during the immediately subsequent fiscal quarter any holder has the option to convert such holder's notes (and the Company is required to notify the trustee under the notes, and the holders of the notes, that this condition to conversion has been met). At any time on or after July 15, 2016, any holder has the option to convert such holder's notes into shares of Griffon common stock. Griffon has the intent and ability to settle the principal component of any conversion of notes in cash. 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 30, 2015, aggregate dividends since the last conversion price adjustment of $0.08 per share would have resulted in an adjustment to the conversion ratio of approximately 0.48%. At both September 30, 2015 and 2014, the 2017 Notes had a capital in excess of par component, net of tax, of $15,720. The fair value of the 2017 Notes approximated $118,875 on September 30, 2015 based upon quoted market prices (level 1 inputs)
[5]	In September 2015, Griffon entered into a $32,280 mortgage loan secured by four properties occupied by Griffon's subsidiaries, refinancing two existing real estate mortgages and providing new mortgages on two existing real estate properties. The loans mature in September 2025, are collateralized by the specific properties financed and are guaranteed by Griffon. The loans bear interest at a rate of LIBOR plus 1.50%.
[6]	In December 2013, Griffon’s Employee Stock Ownership Plan (“ESOP”) entered into an agreement that refinanced the two existing ESOP loans into one new Term Loan in the amount of $21,098 (the "Agreement"). The Agreement also provided for a Line Note with $10,000 available to purchase shares of Griffon common stock in the open market. In July 2014, Griffon's ESOP entered into an amendment of the existing Agreement which provided an additional $10,000 Line Note available to purchase shares in the open market. During 2014, the Line Notes were combined with the Term Loan to form one new Term Loan. The Term Loan bears interest at LIBOR plus 2.38% or the lender’s prime rate, at Griffon’s option. The Term Loan requires quarterly principal payments of $551, with a balloon payment of approximately $30,137 due at maturity on December 31, 2018. During 2014, 1,591,117 shares of Griffon common stock, for a total of $20,000, or $12.57 per share, were purchased with proceeds from the Line Notes. The Term Loan is secured by shares purchased with the proceeds of the loan and with a lien on a specific amount of Griffon assets (which lien ranks pari passu with the lien granted on such assets under the Credit Agreement) and is guaranteed by Griffon
[7]	n December 2013 and May 2014, Northcote Holdings Pty Ltd entered into two unsecured term loans in the outstanding amounts of AUD 12,500 and AUD 20,000. The AUD 12,500 term loan requires quarterly interest payments with principal due upon maturity in December 2016. The AUD 20,000 term loan requires quarterly principal payments of AUD 625, with a balloon payment due upon maturity in May 2017. The loans accrue interest at Bank Bill Swap Bid Rate “BBSY” plus 2.8% per annum (4.98% at September 30, 2015 for each loan). As of September 30, 2015, Griffon had an outstanding combined balance of AUD 31,874 ($22,347 as of September 30, 2015) on the term loans, net of issuance costs.Subsidiaries of Northcote Holdings Pty Ltd also maintain two lines of credit of AUD 3,000 and AUD 5,000 ($2,103 and $3,506, respectively, as of September 30, 2015), which accrue interest at BBSY plus 2.25% per annum (4.43% at September 30, 2015 ) and 2.50% per annum (4.68% at September 30, 2015), respectively. As of September 30, 2015, there was AUD 2,000 ($1,402 as of September 30, 2015) in outstanding borrowings under the lines. Griffon Corporation guarantees the term loans and the AUD 3,000 line of credit; the assets of a subsidiary of Northcote Holdings Pty Ltd secures the AUD 5,000 line of credit.(h)

[1]	On February 27, 2014, in an unregistered offering through a private placement under Rule 144A, Griffon issued, at par, $600,000 of 5.25% Senior Notes due in 2022 (“Senior Notes”); interest is payable semi-annually on March 1 and September 1. Proceeds from the Senior Notes were used to redeem $550,000 of 7.125% senior notes due 2018, to pay a call and tender offer premium of $31,530 and to make interest payments of $16,716, with the balance used to pay a portion of the related transaction fees and expenses. In connection with the issuance of the Senior Notes, all obligations under the $550,000 of 7.125% senior notes due in 2018 were discharged. The Senior Notes are senior unsecured obligations of Griffon guaranteed by certain domestic subsidiaries, and subject to certain covenants, limitations and restrictions. On June 18, 2014, Griffon exchanged all of the Senior Notes for substantially identical Senior Notes registered under the Securities Act of 1933 via an exchange offer. The fair value of Senior Notes approximated $570,000 on September 30, 2014 based upon quoted market prices (level 1 inputs).In connection with these transactions, Griffon capitalized $10,313 of underwriting fees and other expenses incurred related to the issuance and exchange of the Senior Notes, which will amortize over the term of such notes. Griffon recognized a loss on the early extinguishment of debt on the 7.125% senior notes aggregating $38,890, comprised of the $31,530 tender offer premium, the write-off of $6,574 of remaining deferred financing fees and $786 of prepaid interest on defeased notes. (b)On March 13, 2015, Griffon amended its Revolving Credit Facility (“Credit Agreement”) to increase the credit facility from$225,000 to $250,000, extend its maturity from March 28, 2019 to March 13, 2020, and modify certain other provisions of the facility. The facility includes a letter sub-facility with a limit of $50,000 (decreased from $60,000), and a multi-currency sub-facility of $50,000. The Credit Agreement provides for same day borrowings of base rate loans in lieu of a swing line sub-facility. Borrowings under the Credit Agreement may be repaid and re-borrowed at any time, subject to final maturity of the facility, or the occurrence or event of default under the Credit Agreement. Interest is payable on borrowings at either a LIBOR or base rate benchmark rate, in each case without a floor, plus an applicable margin, which adjusts based on financial performance. Current margins are 1.00% for base rate loans and 2.00% for LIBOR loans. 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 negative covenants place limits on Griffon's ability to, among other things, incur indebtedness, incur liens, and make restricted payments and investments. The Credit Agreement also has a minimum liquidity covenant that requires cash and available borrowings under the Credit Agreement in the aggregate to equal or exceed $100 million during the six month period prior to maturity of the 2017 Notes (which mature on January 15, 2017); such covenant will no longer apply after payment in full of the 2017 Notes. Borrowings under the Credit Agreement are guaranteed by Griffon’s material domestic subsidiaries and are secured, on a first priority basis, by substantially all domestic assets of the Company and the guarantors and a pledge of not greater than 65% of the equity interest in each of Griffon’s material, first-tier foreign subsidiaries (except that a lien on the assets of Griffon’s material domestic subsidiaries securing a limited amount of the debt under the credit agreement relating to Griffon's Employee Stock Ownership Plan ranks pari passu with the lien granted on such assets under the Credit Agreement; see footnote (d) below). At September 30, 2015, outstanding borrowings and standby letters of credit were $35,000 and $16,938, respectively, under the Credit Agreement; $198,062 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 current conversion rate of the 2017 Notes is 69.3811 shares of Griffon’s common stock per $1 principal amount of notes, corresponding to a conversion price of $14.41 per share. Prior to July 15, 2016, if for at least 20 trading days out of the last 30 trading days during any fiscal quarter the closing price of Griffon's common stock is 130% or greater than the conversion price on each such trading day, then at any time during the immediately subsequent fiscal quarter any holder has the option to convert such holder's notes (and the Company is required to notify the trustee under the notes, and the holders of the notes, that this condition to conversion has been met). At any time on or after July 15, 2016, any holder has the option to convert such holder's notes into shares of Griffon common stock. Griffon has the intent and ability to settle the principal component of any conversion of notes in cash. 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 30, 2015, aggregate dividends since the last conversion price adjustment of $0.08 per share would have resulted in an adjustment to the conversion ratio of approximately 0.48%. At both September 30, 2015 and 2014, the 2017 Notes had a capital in excess of par component, net of tax, of $15,720. The fair value of the 2017 Notes approximated $118,875 on September 30, 2015 based upon quoted market prices (level 1 inputs)
[3]	In September 2015, Griffon entered into a $32,280 mortgage loan secured by four properties occupied by Griffon's subsidiaries, refinancing two existing real estate mortgages and providing new mortgages on two existing real estate properties. The loans mature in September 2025, are collateralized by the specific properties financed and are guaranteed by Griffon. The loans bear interest at a rate of LIBOR plus 1.50%.
[4]	In December 2013, Griffon’s Employee Stock Ownership Plan (“ESOP”) entered into an agreement that refinanced the two existing ESOP loans into one new Term Loan in the amount of $21,098 (the "Agreement"). The Agreement also provided for a Line Note with $10,000 available to purchase shares of Griffon common stock in the open market. In July 2014, Griffon's ESOP entered into an amendment of the existing Agreement which provided an additional $10,000 Line Note available to purchase shares in the open market. During 2014, the Line Notes were combined with the Term Loan to form one new Term Loan. The Term Loan bears interest at LIBOR plus 2.38% or the lender’s prime rate, at Griffon’s option. The Term Loan requires quarterly principal payments of $551, with a balloon payment of approximately $30,137 due at maturity on December 31, 2018. During 2014, 1,591,117 shares of Griffon common stock, for a total of $20,000, or $12.57 per share, were purchased with proceeds from the Line Notes. The Term Loan is secured by shares purchased with the proceeds of the loan and with a lien on a specific amount of Griffon assets (which lien ranks pari passu with the lien granted on such assets under the Credit Agreement) and is guaranteed by Griffon
[5]	In October 2006, CBP entered into a capital lease totaling $14,290 for real estate in Troy, Ohio. The lease matures in 2022, bears interest at a fixed rate of 5.0%, is secured by a mortgage on the real estate and is guaranteed by Griff
[6]	In September 2015, Clopay Europe GMBH (“Clopay Europe”) entered into a EUR 5,000 ($5,599 as of September 30, 2015) revolving credit facility and a EUR 15,000 ($16,795 as of September 30, 2015) term loan. The term loan is payable in twelve quarterly installments of EUR 1,250, bears interest at a fixed rate of 2.5% and matures in September 2018. The revolving facility matures in November 2016, but is renewable upon mutual agreement with the bank. The revolving credit facility accrues interest at EURIBOR plus 1.75% per annum (1.75% at September 30, 2015). The revolver and the term loan are both secured by substantially all of the assets of Clopay Europe and its subsidiaries. Griffon guarantees the revolving facility and term loan. The term loan had an outstanding balance of EUR 15 million and the revolver had no borrowings outstanding at September 30, 2015. Clopay Europe is required to maintain a certain minimum equity to assets ratio and is subject to a maximum debt leverage ratio (defined as the ratio of total debt to EBITDA). Clopay do Brasil maintains lines of credit of approximately R$12,800 ($3,222 as of September 30, 2015). Interest on borrowings accrues at a rate of Brazilian CDI plus 6.0% (20.13% at September 30, 2015). As of September 30, 2015, there was approximately R$7,652 ($1,926 as of September 30, 2015) borrowed under the lines borrowed under the lines. PPC guarantees the loan and lines.In November 2012, Garant G.P. (“Garant”) entered into a CAD 15,000 revolving credit facility. The facility accrues interest at LIBOR (USD) or the Bankers Acceptance Rate (CDN) plus 1.3% per annum (1.63% LIBOR USD and 2.03% Bankers Acceptance Rate CDN as of September 30, 2015). The revolving facility matures in October 2016. Garant is required to maintain a certain minimum equity. As of September 30, 2015, there were CAD 7,481($5,606 as of September 30, 2015) borrowed under the revolving credit facility with CAD 6,307 ($4,726 as of September 30, 2015) available for borrowin
[7]	n December 2013 and May 2014, Northcote Holdings Pty Ltd entered into two unsecured term loans in the outstanding amounts of AUD 12,500 and AUD 20,000. The AUD 12,500 term loan requires quarterly interest payments with principal due upon maturity in December 2016. The AUD 20,000 term loan requires quarterly principal payments of AUD 625, with a balloon payment due upon maturity in May 2017. The loans accrue interest at Bank Bill Swap Bid Rate “BBSY” plus 2.8% per annum (4.98% at September 30, 2015 for each loan). As of September 30, 2015, Griffon had an outstanding combined balance of AUD 31,874 ($22,347 as of September 30, 2015) on the term loans, net of issuance costs.Subsidiaries of Northcote Holdings Pty Ltd also maintain two lines of credit of AUD 3,000 and AUD 5,000 ($2,103 and $3,506, respectively, as of September 30, 2015), which accrue interest at BBSY plus 2.25% per annum (4.43% at September 30, 2015 ) and 2.50% per annum (4.68% at September 30, 2015), respectively.

Prior to July 15, 2016, if for at least 20 trading days out of the last 30 trading days during any fiscal quarter the closing price of Griffon's common stock is 130% or greater than the conversion price on each such trading day, then at any time during the immediately subsequent fiscal quarter any holder has the option to convert such holder's notes (and the Company is required to notify the trustee under the notes, and the holders of the notes, that this condition to conversion has been met). At any time on or after July 15, 2016, any holder has the option to convert such holder's notes into shares of Griffon common stock. Griffon has the intent and ability to settle the principal component of any conversion of notes in cash. 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 30, 2015, aggregate dividends since the last conversion price adjustment of $0.08 per share would have resulted in an adjustment to the conversion ratio of approximately 0.48%. At both September 30, 2015 and 2014, the 2017 Notes had a capital in excess of par component, net of tax, of $15,720. The fair value of the 2017 Notes approximated $118,875 on September 30, 2015 based upon quoted market prices (level 1 inputs)
[3]	In September 2015, Griffon entered into a $32,280 mortgage loan secured by four properties occupied by Griffon's subsidiaries, refinancing two existing real estate mortgages and providing new mortgages on two existing real estate properties. The loans mature in September 2025, are collateralized by the specific properties financed and are guaranteed by Griffon. The loans bear interest at a rate of LIBOR plus 1.50%.
[4]	In December 2013, Griffon’s Employee Stock Ownership Plan (“ESOP”) entered into an agreement that refinanced the two existing ESOP loans into one new Term Loan in the amount of $21,098 (the "Agreement"). The Agreement also provided for a Line Note with $10,000 available to purchase shares of Griffon common stock in the open market. In July 2014, Griffon's ESOP entered into an amendment of the existing Agreement which provided an additional $10,000 Line Note available to purchase shares in the open market. During 2014, the Line Notes were combined with the Term Loan to form one new Term Loan. The Term Loan bears interest at LIBOR plus 2.38% or the lender’s prime rate, at Griffon’s option. The Term Loan requires quarterly principal payments of $551, with a balloon payment of approximately $30,137 due at maturity on December 31, 2018. During 2014, 1,591,117 shares of Griffon common stock, for a total of $20,000, or $12.57 per share, were purchased with proceeds from the Line Notes. The Term Loan is secured by shares purchased with the proceeds of the loan and with a lien on a specific amount of Griffon assets (which lien ranks pari passu with the lien granted on such assets under the Credit Agreement) and is guaranteed by Griffon
[5]	In October 2006, CBP entered into a capital lease totaling $14,290 for real estate in Troy, Ohio. The lease matures in 2022, bears interest at a fixed rate of 5.0%, is secured by a mortgage on the real estate and is guaranteed by Griff
[6]	In September 2015, Clopay Europe GMBH (“Clopay Europe”) entered into a EUR 5,000 ($5,599 as of September 30, 2015) revolving credit facility and a EUR 15,000 ($16,795 as of September 30, 2015) term loan.

The revolver and the term loan are both secured by substantially all of the assets of Clopay Europe and its subsidiaries. Griffon guarantees the revolving facility and term loan. The term loan had an outstanding balance of EUR 15 million and the revolver had no borrowings outstanding at September 30, 2015. Clopay Europe is required to maintain a certain minimum equity to assets ratio and is subject to a maximum debt leverage ratio (defined as the ratio of total debt to EBITDA). Clopay do Brasil maintains lines of credit of approximately R$12,800 ($3,222 as of September 30, 2015). Interest on borrowings accrues at a rate of Brazilian CDI plus 6.0% (20.13% at September 30, 2015).

The revolving facility matures in October 2016. Garant is required to maintain a certain minimum equity. As of September 30, 2015, there were CAD 7,481($5,606 as of September 30, 2015) borrowed under the revolving credit facility with CAD 6,307 ($4,726 as of September 30, 2015) available for borrowin
[7]	n December 2013 and May 2014, Northcote Holdings Pty Ltd entered into two unsecured term loans in the outstanding amounts of AUD 12,500 and AUD 20,000. The AUD 12,500 term loan requires quarterly interest payments with principal due upon maturity in December 2016. The AUD 20,000 term loan requires quarterly principal payments of AUD 625, with a balloon payment due upon maturity in May 2017.
