Organization, Consolidation and Presentation of Financial Statements [Abstract]
DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION	DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION About Griffon Corporation Griffon Corporation (the “Company” or “Griffon”) is a diversified management and holding company that conducts business through wholly-owned subsidiaries. Griffon oversees the operations of its subsidiaries, allocates resources among them and manages their capital structures. Griffon provides direction and assistance to its subsidiaries in connection with acquisition and growth opportunities as well as in connection with divestitures. In order to further diversify, Griffon also seeks out, evaluates and, when appropriate, will acquire additional businesses that offer potentially attractive returns on capital. Griffon currently conducts its operations through three reportable segments: • Home & Building Products (“HBP”) consists of two companies, The AMES Companies, Inc. (“AMES”) and Clopay Building Products Company, Inc. (“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, Inc. (“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. Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, these financial statements do not include all the information and footnotes required by U.S. GAAP for complete financial statements. As such, they should be read with reference to Griffon’s Annual Report on Form 10-K for the year ended September 30, 2015 , which provides a more complete explanation of Griffon’s accounting policies, financial position, operating results, business properties and other matters. In the opinion of management, these financial statements reflect all adjustments considered necessary for a fair statement of interim results. Griffon’s HBP operations are seasonal; for this and other reasons, the financial results of the Company for any interim period are not necessarily indicative of the results for the full year. The condensed consolidated balance sheet information at September 30, 2015 was derived from the audited financial statements included in Griffon’s Annual Report on Form 10-K for the year ended September 30, 2015 . The consolidated financial statements include the accounts of Griffon and all subsidiaries. Intercompany accounts and transactions have been eliminated on consolidation. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reporting periods. These estimates may be adjusted due to changes in economic, industry or customer financial conditions, as well as changes in technology or demand. Significant estimates include allowances for doubtful accounts receivable and returns, net realizable value of inventories, restructuring reserves, valuation of goodwill and intangible assets, percentage of completion method of accounting, pension assumptions, useful lives associated with depreciation and amortization of intangible and fixed assets, warranty reserves, sales incentive accruals, stock based compensation assumptions, income taxes and tax valuation reserves, environmental reserves, legal reserves, insurance reserves and the valuation of 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. Certain amounts in the prior year have been reclassified to conform to current year presentation.

FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS	6 Months Ended
	Mar. 31, 2016
Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS The carrying values of cash and equivalents, accounts receivable, accounts and notes payable, and revolving credit and variable interest rate 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 and variable rate debt is based upon current market rates. Applicable accounting guidance establishes a fair value hierarchy requiring 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 $588,000 and $115,375 , respectively, on March 31, 2016 . Fair values were based upon quoted market prices (level 1 inputs). Insurance contracts with values of $2,935 at March 31, 2016 , are measured and recorded at fair value based upon quoted prices in active markets for similar assets (level 2 inputs) and are included in Prepaid and other current assets on the Consolidated Balance Sheets. Items Measured at Fair Value on a Recurring Basis At March 31, 2016 , trading securities, measured at fair value based on quoted prices in active markets for similar assets (level 2 inputs), with a fair value of $1,200 ( $1,000 cost basis) were included in Prepaid and other current assets on the Consolidated Balance Sheets. During the first quarter of 2016, the Company settled trading securities with proceeds totaling $715 and recognized a loss of $13 in Other income (expense). During the second quarter of the prior year, the Company settled all outstanding available-for-sale securities with proceeds totaling $8,891 and recognized a gain of $489 in Other income (expense) and, accordingly, a gain of $870 , net of tax, on available-for-sale securities was reclassified out of Accumulated other comprehensive income (loss) ("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 2016, 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 US dollars. At March 31, 2016, Griffon had $33,000 of Australian dollar contracts at a weighted average rate of $1.30 , which qualified for hedge accounting. These hedges were all deemed effective as cash flow hedges with gains and losses related to changes in fair value deferred and recorded in AOCI and Prepaid and other current assets, or Accrued liabilities, until settlement. Upon settlement, gains and losses are recognized in the Consolidated Statements of Operations and Comprehensive Income (Loss) in Cost of goods and services ("COGS"). AOCI included deferred losses of $2,714 ( $1,981 , net of tax) at March 31, 2016 and gains of $181 and $585 were recorded in COGS during the quarter and six months ended March 31, 2016, respectively, for all settled contracts. All contracts expire in 28 to 270 days. At March 31, 2016 , Griffon had $4,615 of Canadian dollar contracts at a weighted average rate of $1.30 . The contracts, which protect Canada operations from currency fluctuations for U.S. dollar based purchases, do not qualify for hedge accounting. For the quarter and six months ended March 31, 2016 , a fair value loss of $385 and $284 were recorded to Other liabilities and to Other income for the outstanding contracts, based on similar contract values (level 2 inputs). All contracts expire in 15 to 180 days.

Business Combinations [Abstract]
ACQUISITIONS	ACQUISITIONS AND INVESTMENTS On February 14, 2016, AMES Australia acquired substantially all of the Intellectual Property (IP) assets of Australia-based Nylex Plastics Pty Ltd. for approximately $1,700 . Through this acquisition, AMES and Griffon secured the ownership of the trademark “Nylex” for certain categories of AMES products, principally in the country of Australia. Previously, the Nylex name was licensed. The acquisition of the Nylex IP was contemplated as a post-closing activity of the Cyclone acquisition and supports AMES' Australian watering products strategy. The purchase price was allocated to indefinite lived trademarks and is not deductible for income taxes. In December 2015, Telephonics invested an additional $2,726 increasing its equity stake from 26% to 49% in Mahindra Telephonics Integrated Systems (MTIS), a joint venture with Mahindra Defence Systems, a Mahindra Group Company. MTIS is an aerospace and defense manufacturing and development facility in Prithla, India. This investment is accounted for using the equity method. 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.

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 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 the Senior Notes approximated $588,000 on March 31, 2016 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 22, 2016, Griffon amended its Revolving Credit Facility (the “Credit Agreement”) to increase the maximum borrowing availability from $250,000 to $350,000 , extend its maturity date from March 13, 2020 to March 22, 2021 and modify certain other provisions of the facility. The facility includes a letter of credit sub-facility with a limit of $50,000 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 1.25% for base rate loans and 2.25% 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. 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 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 ("ESOP") ranks pari passu with the lien granted on such assets under the Credit Agreement; see footnote (e) below). At March 31, 2016 , outstanding borrowings and standby letters of credit were $122,500 and $15,922 , respectively, under the Credit Agreement; $211,578 was available, subject to certain loan covenants, 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 70.1631 shares of Griffon’s common stock per $1 principal amount of notes, corresponding to a conversion price of $14.25 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 note (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; Griffon has the right to settle the conversion of the 2017 Notes in cash, stock or a combination of cash and stock. Griffon has the intent and ability to settle the principal components 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 42 nd trading day prior to maturity of the notes; and (iii) such time as the cumulative adjustment equals or exceeds 1% . At both March 31, 2016 and 2015, 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 $115,375 on March 31, 2016 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 and March 2016, Griffon entered into mortgage loans in the amounts of $32,280 and $8,000 , respectively. The mortgage loans are secured by four properties occupied by Griffon's subsidiaries. The loans mature in September 2025 and April 2018, respectively, are collateralized by the specific properties financed and are guaranteed by Griffon. The loans bear interest at a rate of LIBOR plus 1.50% . At March 31, 2016 , $38,556 was outstanding, net of issuance costs. (e) In December 2013, Griffon’s 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 to 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. As of March 31, 2016 , $35,454 , net of issuance costs, was outstanding under the Term Loan. 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. At March 31, 2016 , $6,850 was outstanding, net of issuance costs. (g) In September 2015, Clopay Europe GmbH (“Clopay Europe”) entered into a EUR 5,000 ( $5,678 as of March 31, 2016 ) revolving credit facility and EUR 15,000 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 September 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 March 31, 2016). 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 has an outstanding balance of EUR 12,500 ( $14,006 at March 31, 2016 , net of issuance costs) and the revolver had no borrowings outstanding at March 31, 2016 . 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 Brazil maintains lines of credit of R$12,800 ( $3,597 as of March 31, 2016 ). Interest on borrowings accrues at a rate of Brazilian CDI plus 6.0% ( 20.13% at March 31, 2016 ). At March 31, 2016 there was approximately R$6,911 ( $1,942 as of March 31, 2016 ) borrowed under the lines. PPC guarantees the loan and lines. In November 2012, Garant G.P. (“Garant”) entered into a CAD $15,000 ( $11,567 as of March 31, 2016) revolving credit facility. The facility accrues interest at LIBOR (USD) or the Bankers Acceptance Rate (CDN) plus 1.3% per annum ( 1.93% LIBOR USD and 2.16% Bankers Acceptance Rate CDN as of March 31, 2016 ). The revolving facility matures in October 2016. This facility is classified as long term debt as Griffon has the intent and ability to refinance the borrowings. Garant is required to maintain a certain minimum equity. At March 31, 2016 , there was CAD $8,371 ( $6,455 as of March 31, 2016 ) borrowed under the revolving credit facility with CAD $6,629 ( $5,112 as of March 31, 2016 ) available for borrowing. In December 2013 and May 2014, Griffon Australia Holdings Pty Ltd (formerly known as Northcote Holdings Australia Pty Ltd) entered into two unsecured term loans in the outstanding amounts of AUD 12,500 and AUD 20,000 , respectively. The AUD 12,500 term loan requires quarterly interest payments with principal due upon maturity in December 2016. This loan is classified as long term debt as Griffon has the intent and ability to refinance the principal amount. 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 ( 5.09% at March 31, 2016 for each loan). As of March 31, 2016 , Griffon had an outstanding combined balance of AUD $30,555 ( $23,432 as of March 31, 2016 ) on the term loans, net of issuance costs. A subsidiary of Northcote Holdings Pty Ltd also maintains a line of credit of AUD 5,000 ( $3,835 as of March 31, 2016 ), which accrues interest at BBSY plus 2.50% per annum ( 4.79% at March 31, 2016 ). At March 31, 2016 , there were AUD 4,000 ( $3,068 as of March 31, 2016) under the lines. 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 a loan with the Pennsylvania Industrial Development Authority with the balance consisting of capital leases. At March 31, 2016 , Griffon and its subsidiaries were in compliance with the terms and covenants of all credit and loan agreements.

Earnings Per Share [Abstract]
EARNINGS PER SHARE (EPS)	EARNINGS PER SHARE (EPS) Basic EPS (and diluted EPS in periods when a loss exists) was calculated by dividing income available to common shareholders by the weighted average number of shares of common stock outstanding during the period. Diluted EPS was calculated by dividing income available to common shareholders by the weighted average number of shares of common stock outstanding plus additional common shares that could be issued in connection with stock based compensation and upon the settlement of the 2017 Convertible notes. In the six months ended March 31, 2015 , the 2017 Notes were anti-dilutive due to the conversion price being greater than the average stock price during the periods presented. The following table is a reconciliation of the share amounts (in thousands) used in computing earnings per share: Three Months Ended March 31, Six Months Ended March 31, 2016 2015 2016 2015 Weighted average shares outstanding - basic 41,426 45,349 41,697 45,829 Incremental shares from stock based compensation 2,059 1,874 2,135 1,853 Convertible debt due 2017 406 446 895 — Weighted average shares outstanding - diluted 43,891 47,669 44,727 47,682 Anti-dilutive options excluded from diluted EPS computation 416 567 418 580 Griffon has the intent and ability to settle the principal amount of the 2017 Notes in cash, and as such, the potential issuance of shares related to the principal amount of the 2017 Notes does not affect diluted shares.

Stockholders' Equity Note [Abstract]
SHAREHOLDERS' EQUITY	SHAREHOLDERS’ EQUITY During 2016, the Company paid a quarterly cash dividend of $0.05 per share in each quarter, totaling $0.10 per share for the six months ended March 31, 2016. During 2015, the Company paid quarterly cash dividends of $0.04 per share, totaling $0.16 per share for the year. Dividends paid on allocated shares in the ESOP were used to pay down the ESOP loan and recorded as a reduction of debt service payments and compensation expense. A dividend payable was established for the holders of restricted shares; such dividends will be released upon vesting of the underlying restricted shares. On May 4, 2016 the Board of Directors declared a quarterly cash dividend of $0.05 per share, payable on June 23, 2016 to shareholders of record as of the close of business on May 27, 2016. Compensation expense for restricted stock is recognized ratably over the required service period based on the fair value of the grant, calculated as the number of shares granted multiplied by the stock price on the date of grant and, for performance shares, 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 SG&A expenses. On January 29, 2016, shareholders approved the Griffon Corporation 2016 Equity Incentive Plan ("Incentive Plan") under which awards of performance shares, performance units, stock options, stock appreciation rights, restricted shares, restricted stock units, deferred shares and other stock-based awards may be granted. Options granted under the Incentive Plan may be either “incentive stock options” or nonqualified stock options, generally expire ten years after the date of grant and 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 2,350,000 ( 600,000 of which may be issued as incentive stock options), plus (i) any shares reserved for issuance under the 2011 Equity Incentive Plan as of the effective date of the Incentive Plan, and (ii) any shares underlying awards outstanding on such effective date under the 2011 Incentive Plan that are canceled or forfeited. As of March 31, 2016 , 1,795,603 shares were available for grant. All grants outstanding under former equity plans will continue under their terms; no additional awards will be granted under such plans. During the first quarter of 2016, Griffon granted 372,243 shares of restricted stock, subject to certain performance conditions, with vesting periods of three years , with a total fair value of $6,425 , or a weighted average fair value of $17.26 per share. During the second quarter of 2016, Griffon granted 677,461 shares of restricted stock consisting of 605,000 shares to two senior executives with a vesting period of four years and a two year post-vesting holding period, and 31,761 shares of restricted stock, subject to certain performance conditions, with a vesting period of three years and a fair value of $473 , or a weighted average fair value of $14.90 per share. Griffon also granted 40,700 shares with a vesting period of three years and a fair value of $618 , or a weighted average fair value of $15.18 per share. The grants issued to two senior executive are subject to the achievement of certain absolute and relative performance conditions relating to the price of Griffon’s common stock. So long as the minimum performance condition is attained, the amount of shares that can vest will range from 220,000 to 605,000 . The total fair value of these restricted shares is approximately $4,247 , or a weighted average fair value of $7.02 . For the quarters ended March 31, 2016 and 2015, stock based compensation expense totaled $2,489 and $2,795 , respectively. For the six months ended March 31, 2016 and 2015, stock based compensation expense totaled $5,555 and $5,372 , respectively. During the quarter and six months ended March 31, 2016 , 1,683 shares, with a market value of $25 or $14.85 per share, and 188,222 shares, with a market value of $3,577 or $19.00 per share, respectively, were withheld to settle employee taxes due to the vesting of restricted stock, and were added to treasury. On each of March 20, 2015 and July 29, 2015, Griffon’s Board of Directors authorized the repurchase of up to $50,000 of Griffon’s outstanding common stock. Under these share repurchase programs, the Company may purchase shares in the open market, including pursuant to a 10b5-1 plan, or in privately negotiated transactions. During the quarter ended March 31, 2016 , Griffon purchased 1,516,919 shares of common stock under both the March 2015 and July 2015 programs, for a total of $22,705 or $14.97 per share.

Accounting Changes and Error Corrections [Abstract]
RECENT ACCOUNTING PRONOUNCEMENTS	RECENT 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 periods 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. In April 2015, the FASB issued guidance on simplifying the presentation of debt issuance costs. This guidance requires 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. In November 2015, the FASB issued guidance on simplifying the presentation of deferred income taxes, requiring deferred income tax liabilities and assets to be classified as non-current in the statement of financial position. This guidance may be applied retrospectively or prospectively to all annual and interim periods presented and is effective for the Company beginning in fiscal 2018; implementation of this guidance is not expected to have a material effect on the Company’s financial condition or results of operations. In February 2016, the FASB issued guidance on lease accounting requiring lessees to recognize a right-of-use asset and a lease liability for long-term leases. The liability will be equal to the present value of lease payments. This guidance must be applied using a modified retrospective transition approach to all annual and interim periods presented and is effective for the company beginning in fiscal 2019. We are currently evaluating the impact of the guidance on the Company's financial condition, results of operations and related disclosures. In March 2016, the FASB issued guidance on simplifying several aspects of accounting for share-based payment award transactions, including income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. This guidance requires a mix of prospective, modified retrospective, and retrospective transition to all annual and interim periods presented and is effective for the Company beginning in fiscal 2018. We are currently evaluating the impact of the guidance on the Company's financial condition, results of operations and related disclosures. 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.

Product Warranties Disclosures [Abstract]
WARRANTY LIABILITY	WARRANTY LIABILITY Telephonics offers warranties against product defects for periods generally ranging from one to two years, depending on the specific product and terms of the customer purchase agreement. Typical warranties require Telephonics to repair or replace the defective products during the warranty period at no cost to the customer. At the time revenue is recognized, Griffon records a liability for warranty costs, estimated based on historical experience, and periodically assesses its warranty obligations and adjusts the liability as necessary. AMES offers an express limited warranty for a period of ninety days on all products from the date of original purchase unless otherwise stated on the product or packaging. Changes in Griffon’s warranty liability, included in Accrued liabilities, were as follows: Three Months Ended March 31, Six Months Ended March 31, 2016 2015 2016 2015 Balance, beginning of period $ 4,778 $ 4,908 $ 4,756 $ 4,934 Warranties issued and changes in estimated pre-existing warranties 1,279 1,842 2,196 2,791 Actual warranty costs incurred (872 ) (1,076 ) (1,767 ) (2,051 ) Balance, end of period $ 5,185 $ 5,674 $ 5,185 $ 5,674

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Legal and environmental Department of Environmental Conservation of New York State (“DEC”), with ISC Properties, Inc. Lightron Corporation (“Lightron”), a wholly-owned subsidiary of Griffon, once conducted operations at a location in Peekskill in the Town of Cortlandt, New York (the “Peekskill Site”) owned by ISC Properties, Inc. (“ISC”), a wholly-owned subsidiary of Griffon. ISC sold the Peekskill Site in November 1982. Subsequently, Griffon was advised by the DEC that random sampling at the Peekskill Site and in a creek near the Peekskill Site indicated concentrations of solvents and other chemicals common to Lightron’s prior plating operations. ISC then entered into a consent order with the DEC in 1996 (the “Consent Order”) to perform a remedial investigation and prepare a feasibility study. After completing the initial remedial investigation pursuant to the Consent Order, ISC was required by the DEC, and did 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 media, 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 media, 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 of New York 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 in calendar 2016. The DEC is expected to issue a Record of Decision approving the selection of a remedial alternative in calendar 2016. Implementation of the selected remedial alternative is expected to occur in 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, Griffon is currently in discussions with the civil division of the U.S. Department of Justice regarding certain amounts the civil division has indicated it believes it is owed from Griffon with respect to certain U.S. government contracts in which Griffon acted as a subcontractor. No claim has been asserted against Griffon in connection with this matter, and Griffon believes that it does not have a material financial exposure in connection with this matter. 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. Operating Leases Griffon rents property and equipment under operating leases expiring at various dates. Most of the real property leases have escalation clauses related to increases in real property taxes. Rent expense for all operating leases totaled approximately $7,305 and $7,638 for the three months ended March 31, 2016 and 2015, respectively and totaled approximately $14,638 and $15,400 for the six months ended March 31, 2016 and 2015, respectively. Aggregate future annual minimum lease payments for operating leases are $26,292 in 2016, $20,741 in 2017, $17,889 in 2018, $14,729 in 2019, $10,041 in 2020 and $9,294 thereafter.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, these financial statements do not include all the information and footnotes required by U.S. GAAP for complete financial statements. As such, they should be read with reference to Griffon’s Annual Report on Form 10-K for the year ended September 30, 2015 , which provides a more complete explanation of Griffon’s accounting policies, financial position, operating results, business properties and other matters. In the opinion of management, these financial statements reflect all adjustments considered necessary for a fair statement of interim results. Griffon’s HBP operations are seasonal; for this and other reasons, the financial results of the Company for any interim period are not necessarily indicative of the results for the full year. The condensed consolidated balance sheet information at September 30, 2015 was derived from the audited financial statements included in Griffon’s Annual Report on Form 10-K for the year ended September 30, 2015 . The consolidated financial statements include the accounts of Griffon and all subsidiaries. Intercompany accounts and transactions have been eliminated on consolidation. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reporting periods. These estimates may be adjusted due to changes in economic, industry or customer financial conditions, as well as changes in technology or demand. Significant estimates include allowances for doubtful accounts receivable and returns, net realizable value of inventories, restructuring reserves, valuation of goodwill and intangible assets, percentage of completion method of accounting, pension assumptions, useful lives associated with depreciation and amortization of intangible and fixed assets, warranty reserves, sales incentive accruals, stock based compensation assumptions, income taxes and tax valuation reserves, environmental reserves, legal reserves, insurance reserves and the valuation of 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. Certain amounts in the prior year have been reclassified to conform to current year presentation.
Fair Value Measurements	FAIR VALUE MEASUREMENTS The carrying values of cash and equivalents, accounts receivable, accounts and notes payable, and revolving credit and variable interest rate 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 and variable rate debt is based upon current market rates. Applicable accounting guidance establishes a fair value hierarchy requiring 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 $588,000 and $115,375 , respectively, on March 31, 2016 . Fair values were based upon quoted market prices (level 1 inputs). Insurance contracts with values of $2,935 at March 31, 2016 , are measured and recorded at fair value based upon quoted prices in active markets for similar assets (level 2 inputs) and are included in Prepaid and other current assets on the Consolidated Balance Sheets. Items Measured at Fair Value on a Recurring Basis At March 31, 2016 , trading securities, measured at fair value based on quoted prices in active markets for similar assets (level 2 inputs), with a fair value of $1,200 ( $1,000 cost basis) were included in Prepaid and other current assets on the Consolidated Balance Sheets. During the first quarter of 2016, the Company settled trading securities with proceeds totaling $715 and recognized a loss of $13 in Other income (expense). During the second quarter of the prior year, the Company settled all outstanding available-for-sale securities with proceeds totaling $8,891 and recognized a gain of $489 in Other income (expense) and, accordingly, a gain of $870 , net of tax, on available-for-sale securities was reclassified out of Accumulated other comprehensive income (loss) ("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 2016, 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 US dollars. At March 31, 2016, Griffon had $33,000 of Australian dollar contracts at a weighted average rate of $1.30 , which qualified for hedge accounting. These hedges were all deemed effective as cash flow hedges with gains and losses related to changes in fair value deferred and recorded in AOCI and Prepaid and other current assets, or Accrued liabilities, until settlement. Upon settlement, gains and losses are recognized in the Consolidated Statements of Operations and Comprehensive Income (Loss) in Cost of goods and services ("COGS"). AOCI included deferred losses of $2,714 ( $1,981 , net of tax) at March 31, 2016 and gains of $181 and $585 were recorded in COGS during the quarter and six months ended March 31, 2016, respectively, for all settled contracts. All contracts expire in 28 to 270 days. At March 31, 2016 , Griffon had $4,615 of Canadian dollar contracts at a weighted average rate of $1.30 . The contracts, which protect Canada operations from currency fluctuations for U.S. dollar based purchases, do not qualify for hedge accounting. For the quarter and six months ended March 31, 2016 , a fair value loss of $385 and $284 were recorded to Other liabilities and to Other income for the outstanding contracts, based on similar contract values (level 2 inputs). All contracts expire in 15 to 180 days.
Inventories	Inventories are stated at the lower of cost (first-in, first-out or average) or market.
New Accounting Pronouncements	n 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 periods 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. In April 2015, the FASB issued guidance on simplifying the presentation of debt issuance costs. This guidance requires 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. In November 2015, the FASB issued guidance on simplifying the presentation of deferred income taxes, requiring deferred income tax liabilities and assets to be classified as non-current in the statement of financial position. This guidance may be applied retrospectively or prospectively to all annual and interim periods presented and is effective for the Company beginning in fiscal 2018; implementation of this guidance is not expected to have a material effect on the Company’s financial condition or results of operations. In February 2016, the FASB issued guidance on lease accounting requiring lessees to recognize a right-of-use asset and a lease liability for long-term leases. The liability will be equal to the present value of lease payments. This guidance must be applied using a modified retrospective transition approach to all annual and interim periods presented and is effective for the company beginning in fiscal 2019. We are currently evaluating the impact of the guidance on the Company's financial condition, results of operations and related disclosures. In March 2016, the FASB issued guidance on simplifying several aspects of accounting for share-based payment award transactions, including income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. This guidance requires a mix of prospective, modified retrospective, and retrospective transition to all annual and interim periods presented and is effective for the Company beginning in fiscal 2018. We are currently evaluating the impact of the guidance on the Company's financial condition, results of operations and related disclosures. 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.

Schedule of Recognized Identified Assets Acquired and Liabilities Assumed	ACQUISITIONS AND INVESTMENTS On February 14, 2016, AMES Australia acquired substantially all of the Intellectual Property (IP) assets of Australia-based Nylex Plastics Pty Ltd. for approximately $1,700 . Through this acquisition, AMES and Griffon secured the ownership of the trademark “Nylex” for certain categories of AMES products, principally in the country of Australia. Previously, the Nylex name was licensed. The acquisition of the Nylex IP was contemplated as a post-closing activity of the Cyclone acquisition and supports AMES' Australian watering products strategy. The purchase price was allocated to indefinite lived trademarks and is not deductible for income taxes. In December 2015, Telephonics invested an additional $2,726 increasing its equity stake from 26% to 49% in Mahindra Telephonics Integrated Systems (MTIS), a joint venture with Mahindra Defence Systems, a Mahindra Group Company. MTIS is an aerospace and defense manufacturing and development facility in Prithla, India. This investment is accounted for using the equity method. 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.

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 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 the Senior Notes approximated $588,000 on March 31, 2016 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 22, 2016, Griffon amended its Revolving Credit Facility (the “Credit Agreement”) to increase the maximum borrowing availability from $250,000 to $350,000 , extend its maturity date from March 13, 2020 to March 22, 2021 and modify certain other provisions of the facility. The facility includes a letter of credit sub-facility with a limit of $50,000 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 1.25% for base rate loans and 2.25% 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. 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 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 ("ESOP") ranks pari passu with the lien granted on such assets under the Credit Agreement; see footnote (e) below). At March 31, 2016 , outstanding borrowings and standby letters of credit were $122,500 and $15,922 , respectively, under the Credit Agreement; $211,578 was available, subject to certain loan covenants, for borrowing at that date.

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 note (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; Griffon has the right to settle the conversion of the 2017 Notes in cash, stock or a combination of cash and stock. Griffon has the intent and ability to settle the principal components 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 42 nd trading day prior to maturity of the notes; and (iii) such time as the cumulative adjustment equals or exceeds 1% . At both March 31, 2016 and 2015, 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 $115,375 on March 31, 2016 based upon quoted market prices (level 1 inputs).

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.
