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. The Company was founded in 1959, is a Delaware corporation headquartered in New York, N.Y. and is listed on the New York Stock Exchange (NYSE:GFF). Griffon currently conducts its operations through two reportable segments: • Home & Building Products (“HBP”) segment consists of two companies, The AMES Companies, Inc. (“AMES”) and Clopay Building Products Company, Inc, (“CBP”): AMES, founded in 1774, is the leading North American manufacturer and a global provider of branded consumer and professional tools, landscaping products, and outdoor lifestyle solutions. In 2018, we acquired ClosetMaid LLC ("ClosetMaid"), a leader in wood and wire closet organization, general living storage and wire garage storage products for homeowners and professionals. CBP, since 1964, is a leading manufacturer and marketer of residential and commercial garage doors and sells to professional dealers and some of the largest home center retail chains in North America. In 2018, we acquired CornellCookson, a leading U.S. manufacturer and marketer of rolling steel door and grille products designed for commercial, industrial, institutional, and retail use. • Defense Electronics segment consists of Telephonics Corporation ("Telephonics"), founded in 1933, a globally recognized leading provider of highly sophisticated intelligence, surveillance and communications solutions for defense, aerospace and commercial customers. 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 (“US GAAP”) for interim financial information, and 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 US GAAP for complete financial statements. As such, they should be read together with Griffon’s Annual Report on Form 10-K for the year ended September 30, 2018 , 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, 2018 was derived from the audited financial statements included in Griffon’s Annual Report on Form 10-K for the year ended September 30, 2018 . The condensed consolidated financial statements include the accounts of Griffon and all subsidiaries. Intercompany accounts and transactions have been eliminated in consolidation. The preparation of financial statements in conformity with US 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 fixed and intangible 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.

FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS	3 Months Ended
	Dec. 31, 2018
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 approximated $910,000 on December 31, 2018 . Fair values were based upon quoted market prices (level 1 inputs). Insurance contracts with values of $1,975 at December 31, 2018 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 December 31, 2018 , trading securities, measured at fair value based on quoted prices in active markets for similar assets (level 2 inputs), with a fair value of $2,567 ( $2,086 cost basis), were included in Prepaid and other current assets on the Consolidated Balance Sheets. Realized and unrealized gains and losses on trading 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 effects 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. As of December 31, 2018 , 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 December 31, 2018 , Griffon had $16,000 of Australian dollar contracts at a weighted average rate of $1.42 which qualified for hedge accounting (level 2 inputs). These hedges were all deemed effective as cash flow hedges with gains and losses related to changes in fair value deferred and recorded in Accumulated other comprehensive income (loss) ("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 gains of $881 ( $574 , net of tax) at December 31, 2018 and a gain of $692 was recorded in COGS during the three months ended December 31, 2018 , respectively, for all settled contracts. All contracts expire in 30 to 150 days. At December 31, 2018 , Griffon had $940 of Canadian dollar contracts at a weighted average rate of $1.36 . The contracts, which protect Canadian operations from currency fluctuations for US dollar based purchases, do not qualify for hedge accounting. For the three months ended December 31, 2018 , fair value losses of $41 was recorded to Other liabilities and to Other income for the outstanding contracts, based on similar contract values (level 2 inputs). Realized losses of $10 were recorded in Other income during the three months ended December 31, 2018 , respectively, for all settled contracts. All contracts expire in 30 to 210

REVENUE

Revenue from Contract with Customer [Abstract]
REVENUE	REVENUE On October 1, 2018, the Company adopted the requirements of Accounting Standard Codification (“ASC”) Topic 606, “Revenue from Contracts with Customers”, using the modified retrospective method applied to those contracts that were not completed as of October 1, 2018. The Company’s comparative consolidated results over the prior period have not been adjusted and continue to be reported under previously issued guidance, ASC 605 - Revenue Recognition, which required that revenue was accounted for when the earnings process was complete. This accounting standard did not materially impact the Company’s revenue recognition practices in our Home and Building Products (“HBP”) Segment, however, it impacted revenue recognition practices in our Defense Electronics Segment. The impact of adopting this accounting standard was not material to the Company’s consolidated financial statements as of and for the three months ended December 31, 2018. Under the modified retrospective method, the Company recognized the cumulative effect of initially applying this accounting standard as an adjustment to the opening balance in retained earnings of approximately $5,673 , primarily relating to certain contracts in the Defense Electronics Segment containing provisions for radar and communication products that have an alternative use and / or no right to payment. For these contracts, the Company now recognizes revenue at a point in time, rather than over time as this measure more accurately depicts the transfer of control to the customer relative to the goods or services promised under the contract. The cumulative effect of the changes made to the Company's Consolidated October 1, 2018 Balance Sheet for the adoption of ASC 606 is as follows: Balance Sheet As Reported at September 30, 2018 Adjustments Balance as of October 1, 2018 CURRENT ASSETS Contract costs and recognized income not yet billed, net of progress payments $ 121,803 $ (20,982 ) $ 100,821 Inventories 398,359 22,025 420,384 Total Current Assets 912,874 1,043 913,917 Total Assets 2,084,890 1,043 2,085,933 CURRENT LIABILITIES Accounts payable 233,658 8,282 241,940 Billings in excess of costs (1) 17,559 8,282 25,841 Total Current Liabilities 393,071 8,282 401,353 OTHER LIABILITIES 106,710 (1,566 ) 105,144 Total Liabilities 1,610,499 6,716 1,617,215 SHAREHOLDERS' EQUITY Retained Earnings 550,523 (5,673 ) 544,850 Total Shareholders' Equity 474,391 (5,673 ) 468,718 Total Liabilities and Shareholders’ Equity $ 2,084,890 $ 1,043 $ 2,085,933 (1) Billings in excess of costs is reported in Accounts payable on the Company's Consolidated Balance Sheets.

See Note 12 - Business Segments for revenue from contracts with customers disaggregated by end markets, segments and geographic location. Performance Obligations A performance obligation is a promise in a contract to transfer a distinct good or service, or a bundle of goods or services, to the customer, and is the unit of accounting under ASC Topic 606. A contract with a customer is an agreement which both parties have approved, that creates enforceable rights and obligations, has commercial substance and where payment terms are identified and collectability is probable. Once the Company has entered a contract or purchase order, it is evaluated to identify performance obligations. For each performance obligation, revenue is recognized when control of the promised products is transferred to the customer, or services are satisfied under the contract or purchase order, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those products or services (the transaction price). A contracts transaction price is allocated to each distinct performance obligation and recognized as revenue when each performance obligation is satisfied. A majority of the Company’s contracts have a single performance obligation which represents, in most cases, the product being sold to the customer. To a lesser extent, some contracts include multiple performance obligations such as a product, the related installation and, extended warranty services. These contracts require judgment in determining the number of performance obligations. Over 80% of the Company’s performance obligations are recognized at a point in time that relate to the manufacture and sale of a broad range of products and components within the HBP Segment, and revenue is recognized when title, and risk and rewards of ownership have transferred to the customer. Less than 20% of the Company’s performance obligations are recognized over time or under the percentage-of-completion method relating to prime or subcontractors from contract awards with the U.S. Government, as well as foreign governments and other commercial customers within our Defense Electronics Segment. Sales recognized over time are generally accounted for using an input measure to determine progress completed at the end of the period. We believe that cumulative costs incurred to date as a percentage of estimated total contract costs at completion is an appropriate measure of progress towards satisfaction of performance obligations, as it most accurately depicts the progress of our work and transfer of control to our customers. Revenue from HBP Segment A majority of the HBP Segment revenue is short cycle in nature with shipments occurring within one year from order and does not include a material long-term financing component, implicitly or explicitly. Payment terms generally range between 15 to 90 days and vary by the location of the business, the type of products manufactured to be sold and the volume of products sold, among other factors. The Company’s HBP Segment recognizes revenue from product sales when all factors are met, including when control of a product transfers to the customer upon its shipment, completion of installation, testing, certification or other substantive acceptance required under the contract. Other than standard product warranty provisions, sales arrangements provide for no other significant post-shipment obligations on the Company. 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 and allowances based upon historical returns experience. The majority of the Company’s contracts in the HBP Segment offers assurance-type warranties in connection with the sale of a product to a customer. Assurance-type warranties provide a customer with assurance that the related product will function as the parties intended because it complies with agreed-upon specifications. Such warranties do not represent a separate performance obligation. Payment terms in the HBP Segment vary depending on the type and location of the customer and the products or services offered. Generally, the period between the time revenue is recognized and the time payment is due is not significant. Shipping and handling charges are not considered a separate performance obligation. If revenue is recognized for a good before it is shipped and handled, the related shipping and handling costs must be accrued. Additionally, all taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction and collected from a customer (e.g., sales, use, value added, and some excise taxes) are excluded from revenue. The Company's policies related to shipping, handling and taxes have not changed with the adoption of ASC 606. Revenue from Defense Electronics Segment The Company’s Defense Electronics segment earns a substantial portion of its revenue as either a prime contractor or subcontractor from contract awards with the U.S. Government, as well as foreign governments and other commercial customers. These contracts are typically long-term in nature, usually greater than one year and do not include a material long-term financing component, either implicitly or explicitly. Revenue and profits from such contracts are recognized under the percentage-of-completion (over time) 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 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 contracts estimated costs at completion and estimated profit or loss are often required as experience is gained, more information is obtained (even though the scope of work required under the contract may or may not change) and contract modifications occur. The impact of such adjustments to estimates is made on a cumulative basis in the period when such information has become known. For the three months ended December 31, 2018 and 2017, income from operations included net favorable/(unfavorable) catch-up adjustments approximating $(2,500) and $500 , 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 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 with multiple performance obligations, judgment is required to determine whether performance obligations specified in these contacts are distinct and should be accounted for as separate revenue transactions for recognition purposes. In these types of contracts, the Company allocates the total transaction price to each performance obligation in an amount based on the estimated relative standalone selling prices of the promised goods or services underlying each performance obligation. The Company uses an observable price to determine the stand-alone selling price for separate performance obligations or a cost plus margin approach when one is not available. 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 December 31, 2018 and September 30, 2018 was approximately $9,700 and $12,200 , respectively, 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. Substantially all of Telephonics’ U.S. Government end-user contracts contain a termination for convenience clause, regardless whether Telephonics is the prime contractor or the subcontractor. This clause generally entitles Telephonics, upon a termination for convenience, to receive the purchase price for delivered items, reimbursement of allowable work-in-process costs, and an allowance for profit. Allowable costs would include the costs to terminate existing agreements with suppliers. From time to time, Telephonics may combine contracts if they are negotiated together, have specific requirements to combine, or are otherwise closely related. Transaction Price Allocated to the Remaining Performance Obligations On December 31, 2018, we had $366,700 of remaining performance obligations, which we also refer to as total backlog. We expect to recognize approximately 70% of our remaining performance obligations as revenue by year-end 2019, with the balance to be completed thereafter. Backlog represents the dollar value of funded orders for which work has not been performed. Backlog generally increases with bookings, and converts into revenue as we incur costs related to contractual commitments or the shipment of product. Given the nature of our business and a larger dependency on international customers, our bookings, and therefore our backlog, is impacted by the longer maturation cycles resulting in delays in the timing and amounts of such awards, which are subject to numerous factors, including fiscal constraints placed on customer budgets; political uncertainty; the timing of customer negotiations; and the timing of governmental approvals. Contract Balances Contract assets were $89,232 as of December 31, 2018 compared to $121,803 as of September 30, 2018. The $32,571 decrease in our contract assets balance was primarily due to the implementation of ASC 606. Excluding the impact of ASC 606, the decrease was primarily due to the timing of billings and work performed on various radar and surveillance programs. Contract assets primarily relate to the Company's right to consideration for work completed but not billed at the reporting date and are recorded in Contract costs and recognized income not yet billed, net of progress payments in the Consolidated Balance Sheets. Contract assets are transferred to receivables when the right to consideration becomes unconditional. 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 December 31, 2018 and September 30, 2018, approximately $31,400 and $29,500 , respectively, of contract costs and recognized income not yet billed were expected to be collected after one year. As of December 31, 2018 and September 30, 2018, the unbilled receivable balance included $793 and $400 , respectively, of reserves for contract risk. Contract liabilities were $29,113 as of December 31, 2018 compared to $17,559 as of September 30, 2018. The $11,554

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 goodwill 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; in each instance, Griffon is in the process of finalizing the initial purchase price allocation unless otherwise noted. On June 4, 2018, CBP completed the acquisition of 100% of the outstanding stock of CornellCookson, a leading US manufacturer and marketer of rolling steel door and grille products designed for commercial, industrial, institutional and retail use, for $180,000 , excluding the estimated present value of tax benefits, and $12,426 of post-closing adjustments, primarily consisting of a working capital adjustment, of which $9,219 was paid in October 2018. The acquisition of CornellCookson substantially expanded CBP’s non-residential product offerings, and added an established professional dealer network focused on rolling steel door and grille products for commercial, industrial, institutional and retail use. There is no other contingent consideration arrangement relative to the acquisition of CornellCookson. CornellCookson’s accounts, affected for adjustments to reflect fair market values assigned to assets purchased and liabilities assumed, and results of operations are included in the Company’s consolidated financial statements from the date of acquisition. The Company has recorded a preliminary allocation of the purchase price to the Company’s tangible and identifiable intangible assets acquired and liabilities assumed based on their fair market values (level 3 inputs) at the acquisition date. The excess of the purchase price over the fair value of the net tangible and intangible assets was recorded as goodwill and is deductible for tax purposes. Goodwill recognized at the acquisition date represents the other intangible benefits that the Company will derive from the ownership of CornellCookson, however, such intangible benefits do not meet the criteria for recognition of separately identifiable intangible assets. The calculation of the preliminary purchase price allocation, which is pending finalization of tax-related items and completion of the related final valuation, is as follows: Accounts receivable (1) $ 30,400 Inventories (2) 12,336 Property, plant and equipment 49,426 Goodwill 43,183 Intangible assets 67,600 Other current and non-current assets 2,648 Total assets acquired 205,593 Accounts payable and accrued liabilities 12,507 Long-term liabilities 660 Total liabilities assumed 13,167 Total $ 192,426 (1) Includes $30,818 of gross accounts receivable of which $418 was not expected to be collected. The fair value of accounts receivable approximated book value acquired. (2) Includes $13,434 of gross inventory of which $1,098 was reserved for obsolete inventory. The preliminary amounts assigned to goodwill and major intangible asset classifications, all of which are tax deductible, for the CornellCookson acquisition are as follows: Average Goodwill $ 43,183 N/A Indefinite-lived intangibles 53,500 N/A Definite-lived intangibles 14,100 12 Total goodwill and intangible assets $ 110,783 On February 13, 2018, AMES acquired 100% of the outstanding stock of Kelkay Limited ("Kelkay"), a leading United Kingdom manufacturer and distributor of decorative outdoor landscaping products sold to garden centers, retailers and grocers in the UK and Ireland for $56,118 (GBP 40,452 ), subject to contingent consideration of up to GBP 7,000 . This acquisition broadened AMES' product offerings in the market and increased its in-country operational footprint. The purchase price was primarily allocated to tradenames of GBP 19,000 , customer related intangibles of GBP 6,640 , accounts receivable and inventory of GBP 8,894 and fixed asset and land of GBP 8,241 . On November 6, 2017, AMES acquired 100% of the outstanding stock of Harper Brush Works ("Harper"), a division of Horizon Global, for $4,383 , inclusive of post-closing adjustments. Harper is a leading U.S. manufacturer of cleaning products for professional, home, and industrial use. The acquisition expanded AMES’ long-handled tool offering in North America to include brooms, brushes, and other cleaning tools and accessories. The purchase price was primarily allocated to intangible assets of $2,300 , inventory and accounts receivable of $3,900 and fixed assets of $900 . On October 2, 2017, Griffon Corporation completed the acquisition of 100% of the outstanding stock of ClosetMaid, a market leader in home storage and organization products, for approximately $185,700 , inclusive of certain post-closing adjustments and excluding the present value of net tax benefits from the transaction. The acquisition of ClosetMaid expanded Griffon’s Home and Building Products segment into the highly complementary home storage and organization category with a leading brand and product portfolio. ClosetMaid's accounts, affected for adjustments to reflect fair market values assigned to assets purchased and liabilities assumed, and results of operations, are included in the Company’s consolidated financial statements from the date of acquisition. The Company has recorded an allocation of the purchase price to the Company’s tangible and identifiable intangible assets acquired and liabilities assumed based on their fair market values (level 3 inputs) at the acquisition date. The excess of the purchase price over the fair value of the net tangible and intangible assets was recorded as goodwill and is deductible for tax purposes. Goodwill recognized at the acquisition date represents the other intangible benefits that the Company will derive from the ownership of ClosetMaid, however, such intangible benefits do not meet the criteria for recognition of separately identifiable intangible assets. The calculation of the final purchase price allocation is as follows: Accounts receivable (1) $ 32,234 Inventories (2), (3) 28,411 Property, plant and equipment 47,464 Goodwill 70,159 Intangible assets 74,580 Other current and non-current assets 3,852 Total assets acquired 256,700 Accounts payable and accrued liabilities 68,251 Long-term liabilities 2,720 Total liabilities assumed 70,971 Total $ 185,729 (1) Includes $32,956 of gross accounts receivable of which $722 was not expected to be collected. The fair value of accounts receivable approximated book value acquired. (2) Includes $29,079 of gross inventory of which $668 was reserved for obsolete inventory. The fair value of inventory approximated book value acquired. (3) Includes $1,500 in inventory basis step-up, which was charged to cost of goods sold over the inventory turns of the acquired entity. The amounts assigned to goodwill and major intangible asset classifications, all of which are tax deductible, for the ClosetMaid acquisition are as follows: Average Goodwill $ 70,159 N/A Indefinite-lived intangibles 47,740 N/A Definite-lived intangibles 26,840 21 Total goodwill and intangible assets $ 144,739 The Company did not incur any acquisition costs during the three months ended December 31, 2018. During the three months ended December 31, 2017, SG&A and Cost of goods and services included acquisition costs of $1,685 and $1,500

As of December 31, 2018 , outstanding Senior Notes due totaled $1,000,000 ; interest is payable semi-annually on March 1 and September 1. The net proceeds of the $275,000 add-on offering were used to acquire ClosetMaid with the remaining proceeds used to pay down outstanding loan borrowings under Griffon's Revolving Credit Facility (the "Credit Agreement"). The net proceeds of the previously issued $125,000 add-on offering were used to pay down outstanding revolving loan borrowings under the Credit Agreement. The Senior Notes are senior unsecured obligations of Griffon guaranteed by certain domestic subsidiaries, and subject to certain covenants, limitations and restrictions. On February 5, 2018, July 20, 2016 and June 18, 2014, Griffon exchanged all of the $275,000 , $125,000 and $600,000 Senior Notes, respectively, for substantially identical Senior Notes registered under the Securities Act via an exchange offer. The fair value of the Senior Notes approximated $910,000 on December 31, 2018 based upon quoted market prices (level 1 inputs). In connection with the issuance and exchange of the $275,000 senior notes, Griffon capitalized $8,472 of underwriting fees and other expenses; in addition to the $13,329 capitalized under previously issued $600,000 Senior Notes. All capitalized fees for the Senior notes will amortize over the term of the notes and, at December 31, 2018 , $12,017 remained to be amortized. (b) On March 22, 2016, Griffon amended the Credit Agreement to increase the commitments under the credit facility 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. On October 2, 2017 and on May 31, 2018, Griffon amended the Credit Agreement in connection with the ClosetMaid and CornellCookson acquisitions, respectively, to among other things, modify the net leverage covenant. The facility includes a letter of credit sub-facility with a limit of $50,000 and a multi-currency sub-facility of $100,000 . The Credit Agreement provides for same day borrowings of base rate loans. Borrowings under the Credit Agreement may be repaid and re-borrowed at any time, subject to final maturity of the facility or the occurrence of an 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 1.75% for base rate loans and 2.75% 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 (c) below). At December 31, 2018 , under the Credit Agreement, there were $57,500 outstanding borrowings; outstanding standby letters of credit were $14,667 ; and $277,833 was available, subject to certain loan covenants, for borrowing at that date. (c) In September 2015 and March 2016, Griffon entered into mortgage loans in the amounts of $32,280 and $8,000 , respectively, and were due to mature in September 2025 and April 2018, respectively. The mortgage loans were secured and collateralized by four properties occupied by Griffon's subsidiaries and were guaranteed by Griffon. The loans had an interest rate of LIBOR plus 1.50% . The loans were paid off during the year ended September 30, 2018. (d) In August 2016, Griffon’s ESOP entered into an agreement that refinanced the existing ESOP loan into a new Term Loan in the amount of $35,092 (the "Agreement"). The Agreement also provided for a Line Note with $10,908 available to purchase shares of Griffon common stock in the open market. During 2017, Griffon's ESOP purchased 621,875 shares of common stock for a total of $10,908 or $17.54 per share, under a borrowing line that has now been fully utilized. On June 30, 2017, the Term Loan and Line Note were combined into a single Term Loan. The Term Loan bears interest at LIBOR plus 3.00% . The Term Loan requires quarterly principal payments of $569 with a balloon payment due at maturity on March 22, 2020. As a result of the special cash dividend of $1.00 per share, paid on April 16, 2018, the outstanding balance of the Term Loan was reduced by $5,705 . As of December 31, 2018 , $33,970 , 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. (e) Two Griffon subsidiaries have capital leases outstanding for real estate located in Troy, Ohio and Ocala, Florida. The leases mature in 2021 and 2022 , respectively, and bear interest at fixed rates of approximately 5.0% and 8.0% , respectively. The Troy, Ohio lease is secured by a mortgage on the real estate and is guaranteed by Griffon. The Ocala, Florida lease contains two five -year renewal options. At December 31, 2018 , $6,669 was outstanding, net of issuance costs. (f) In November 2012, Garant G.P. (“Garant”) entered into a CAD $15,000 ( $11,018 as of December 31, 2018 ) revolving credit facility. The facility accrues interest at LIBOR (USD) or the Bankers Acceptance Rate (CDN) plus 1.3% per annum ( 4.11% LIBOR USD and 3.50% Bankers Acceptance Rate CDN as of December 31, 2018 ). The revolving facility matures in October 2019. Garant is required to maintain a certain minimum equity. At December 31, 2018 , there were no borrowings under the revolving credit facility with CAD 15,000 ( $11,018 as of December 31, 2018) available for borrowing. In July 2016, Griffon Australia Holdings Pty Ltd and its Australian subsidiaries ("Griffon Australia") entered into an AUD 30,000 term loan and an AUD 10,000 revolver. The term loan refinanced two existing term loans and the revolver replaced two existing lines. In December 2016, the amount available under the revolver was increased from AUD 10,000 to AUD 20,000 and, in March 2017, the term loan commitment was increased by AUD 5,000 . In September 2017, the term commitment was increased by AUD 15,000 . The term loan requires quarterly principal payments of AUD 1,250 plus interest with a balloon payment of AUD 37,125 due upon maturity in October 2019, and accrues interest at Bank Bill Swap Bid Rate “BBSY” plus 2.00% per annum ( 4.11% at December 31, 2018 ).

During 2018, the Company paid a quarterly cash dividend of $0.07 per share. Dividends paid on shares in the ESOP were used to offset ESOP loan payments 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 January 31, 2019, the Board of Directors declared a quarterly cash dividend of $0.0725 per share, payable on March 21, 2019 to shareholders of record as of the close of business on February 21, 2019. 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. On January 31, 2018, shareholders approved Amendment No. 1 to the Incentive Plan pursuant to which, among other things, 1,000,000 shares were added 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 3,350,000 ( 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 December 31, 2018 , there were 324,326 shares 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 2019, Griffon granted 1,194,538 shares of restricted stock and restricted stock units. This included 666,538 shares of restricted stock and restricted stock units, subject to certain performance conditions, with vesting periods of three years , with a total fair value of $8,105 , or a weighted average fair value of $12.16 per share. This also included 528,000 shares of restricted stock granted to two senior executives with a vesting period of four years and a two year post-vesting holding period, 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 384,000 to 528,000 . The total fair value of these restricted shares is approximately $3,576 , or a weighted average fair value of $6.77 . For the quarters ended December 31, 2018 and 2017 , stock based compensation expense totaled $2,933 and $2,555 , respectively. On each of August 3, 2016 and August 1, 2018, Griffon’s Board of Directors authorized the repurchase of up to $50,000 of Griffon’s outstanding common stock. Under this share repurchase program, the Company may purchase shares in the open market, including pursuant to a 10b5-1 plan, or in privately negotiated transactions.

Retirement Benefits [Abstract]
EMPLOYEE BENEFIT PLANS	EMPLOYEE BENEFIT PLANS In March 2017, the FASB issued ASU 2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost, which changed certain presentation and disclosure requirements for employers that sponsor defined benefit and post-retirement pension plans. The new standard requires the service cost component of the net benefit cost to be in the same line item as other compensation in operating income and the other components of net benefit cost, including interest costs, amortization of prior service cots, recognized actuarial costs, to be presented outside of operating income on a retrospective basis. The standard was effective for fiscal years beginning after December 15, 2017. The Company adopted the requirements of the standard in the first quarter of 2019 on a retrospective basis reclassifying the other components of the net periodic benefit costs from Selling, general and administrative expenses to a non-service expense within Other income (expense). The defined benefit and post-retirement pension plans did not have a service cost component. The Company utilized a practical expedient included in the accounting guidance which allowed the Company to use amounts previously disclosed in its pension and other post-retirement benefits note for the prior period as the estimation basis for applying the required retrospective presentation requirements. The Company’s non-service cost components of net periodic benefit cost was a benefit of $787 and $882 during the three months ended December 31, 2018 and 2017, respectively. The impact of this adoption resulted in a reclassification to the Company’s Consolidated Statements of Operations and Comprehensive Income (Loss) for the three months ended December 31, 2017, in which previously reported selling, general and administrative expenses was increased by $882 , with a corresponding decrease to Other income (expense). Defined benefit pension expense (income) was as follows: The remaining provisions of the standard did not have a material impact on our financial position, results of operations or liquidity. Defined benefit pension expense (income) was as follows: Three Months Ended December 31, 2018 2017 Interest cost $ 1,570 $ 1,407 Expected return on plan assets (2,583 ) (2,639 ) Amortization: Prior service cost 4 4 Recognized actuarial loss 222 346 Net periodic expense (income) $ (787 ) $ (882 ) As a result of the recent passing of our Chairman of the Board, who participated in a Supplemental Executive Retirement Plan relating to his tenure as Chief Executive Officer (a position from which he retired in 2008), the pension benefit liability was reduced by $13,715

Accounting Changes and Error Corrections [Abstract]
RECENT ACCOUNTING PRONOUNCEMENTS	RECENT ACCOUNTING PRONOUNCEMENTS In May 2017, the FASB issued guidance to address the situation when a company modifies the terms of a stock compensation award previously granted to an employee. This guidance is effective, and should be applied prospectively, for fiscal years beginning after December 15, 2017. Early adoption is permitted as of the beginning of an annual period. The new guidance is effective for the Company beginning in fiscal 2019. The Company adopted this guidance as of October 1, 2018 and it did not have a material impact on the Company's financial condition, results of operations and related disclosures. In March 2017, the FASB issued amendments to the Compensation - Retirement Benefits guidance which requires companies to retrospectively present the service cost component of net periodic benefit cost for pension and retiree medical plans along with other compensation costs in operating income and present the other components of net periodic benefit cost below operating income in the income statement. The guidance also allows only the service cost component of net periodic benefit cost to be eligible for capitalization within inventory or fixed assets on a prospective basis. This guidance was effective for fiscal years beginning after December 15, 2017. The Company adopted the requirements of the standard in the first quarter of 2019 on a retrospective basis reclassifying the other components of the net periodic benefit costs from Selling, general and administrative expenses to a non-service expense within Other (income) expense, net. This guidance did not have a material impact on the Company's results of operations. See Note 13 - Employee Benefit Plans for further information on the implementation of this guidance. In January 2017, the FASB issued guidance that clarifies the definition of a business, which will impact many areas of accounting including acquisitions, disposals, goodwill, and consolidation. The new standard is intended to help companies and other organizations evaluate whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. This guidance is effective for annual periods beginning after December 15, 2017, including interim periods within those periods and will be effective for the Company beginning in fiscal 2019. The Company adopted the requirements of the standard in the first quarter of 2019 and it did not have a material impact on the Company's financial condition, results of operations and related disclosures. In August 2016, the FASB issued guidance on the Statement of Cash Flows Classification of certain cash receipts and cash payments (a consensus of the FASB Emerging Issues Task Force). This guidance addresses the following eight specific cash flow issues: Debt prepayment or debt extinguishment costs; settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing; contingent consideration payments made after a business combination; proceeds from the settlement of insurance claims; proceeds from the settlement of corporate-owned life insurance policies (including bank-owned life insurance policies); distributions received from equity method investees; beneficial interests in securitization transactions; and separately identifiable cash flows and application of the predominance principle. This guidance will be effective for the Company beginning in fiscal 2019. The Company adopted the requirements of the standard in the first quarter of 2019 and it did not have a material impact on the Company's financial condition, results of operations and cash flows. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) which supersedes nearly all existing revenue recognition guidance. Subsequent to the issuance of Topic 606, the FASB clarified the guidance through several ASUs; hereinafter the collection of revenue guidance is referred to as “ASC 606”. The core principle of ASC 606 is that revenue should be recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. On October 1, 2018, the Company adopted ASC 606 using the modified retrospective method for all contracts. Results for reporting periods beginning October 1, 2018 are presented under ASC 606, while prior period amounts were not adjusted and continue to be reported in accordance with the Company’s historic accounting under Topic 605, Revenue Recognition. The Company recorded a net increase to beginning retained earnings of approximately $5,673 as of October 1, 2018 due to the cumulative impact of adopting ASC 606. The impact to beginning retained earnings primarily related to certain contracts in the Defense Electronics Segment containing provisions for radar and communication products that have an alternative use and/or no right to payment. The adoption of ASC 606 did not have a material impact on the Company’s Consolidated Condensed Financial Statements as of and for the three month period ended December 31, 2018. See Note 3 - Revenue for additional disclosures required by ASC 606. Issued but not yet effective accounting pronouncements In February 2018, the FASB issued guidance that allows companies to reclassify stranded tax effects resulting from the 2017 Tax Cuts and Jobs Act (the Tax Act), from accumulated other comprehensive income to retained earnings. This guidance is effective for all entities for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years, with early adoption permitted. The new standard is effective for the Company beginning in 2020, with early adoption permitted. We are currently evaluating the effects that the adoption of this guidance will have on our consolidated financial statements and the related disclosures. In January 2017, the FASB issued guidance that simplifies how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit's goodwill with the carrying amount of that goodwill. This guidance is effective for annual periods beginning after December 15, 2019, including interim periods within those periods and will be effective for the Company beginning October 1, 2020. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. We are currently evaluating the impact of the guidance on the Company's financial condition, results of operations and related disclosures. 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 2020. We are currently evaluating the impact of the guidance on the Company's financial condition, results of operations and related disclosures.

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, ISC 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. After receiving public comments on the PRAP, the DEC issued a Record of Decision (“ROD”) in June 2011 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. At the time of adoption of the ROD, the approximate cost of the remedy proposed by DEC in the PRAP was approximately $10,000 . Based on our periodic review of public records, we recently became aware of a letter that the United States Environmental Protection Agency (the “EPA”) recently made available on its website. In this letter, dated August 2018, the DEC requested that the Peekskill Site be nominated by the EPA for inclusion on the National Priorities List. The DEC also indicated in this letter that it conducted subsequent investigative work that resulted in findings suggesting that the extent of contamination is greater than what was assumed at the time the ROD was issued. We are unaware of any attempt by the EPA to contact Lightron, ISC or its advisors, and therefore we cannot assess or predict how the EPA will react to the letter from the DEC. Absent action by the EPA, we would expect that the DEC will enter into negotiations with potentially responsible parties (“PRPs”) to request they undertake performance of the remedies selected in the ROD. The DEC might also begin a process in which it seeks to amend the ROD or issue a new ROD, in which case it may then seek to enter into negotiations with PRPs to request they undertake performance of the remedies selected in an amended or new ROD. Griffon does not acknowledge any responsibility to perform any remediation at the Peekskill Site. Improper Advertisement Claim involving Union Tools ® Products. Beginning in December 2004, a customer of AMES had been named in various litigation matters relating to certain Union Tools products. The plaintiffs in those litigation matters asserted causes of action against the customer of AMES for improper advertisement to end consumers. The allegations suggested that advertisements led the consumers to believe that Union Tools’ hand tools were wholly manufactured within boundaries of the United States. The complaints asserted various causes of action against the customer of AMES under federal and state law, including common law fraud. At some point, 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 has approved the final remedial investigation and feasibility study reports. AMES’ recommended remedial option of excavation and offsite disposal of lead contaminated soils, capping of other areas of the site impacted by other metals and performing limited groundwater monitoring was accepted by the DEC in a Record of Decision issued March 1, 2018. The Company has submitted a final design and implementation work plan to the State of New York and is awaiting approval. Implementation of the selected remedial alternative is expected to be completed in 2019. AMES has a number of defenses to liability in this matter, including its rights under a previous 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, the Defense Criminal Investigative Service, and the Department of Justice which has responsibility for asserting claims on behalf of the U.S. Government. 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

DESCRIPTION OF BUSINESS AND B_2

DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION (Policies)	3 Months Ended
	Dec. 31, 2018
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 (“US GAAP”) for interim financial information, and 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 US GAAP for complete financial statements. As such, they should be read together with Griffon’s Annual Report on Form 10-K for the year ended September 30, 2018 , 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, 2018 was derived from the audited financial statements included in Griffon’s Annual Report on Form 10-K for the year ended September 30, 2018 . The condensed consolidated financial statements include the accounts of Griffon and all subsidiaries. Intercompany accounts and transactions have been eliminated in consolidation. The preparation of financial statements in conformity with US 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 fixed and intangible 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.
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. •
Inventories	Inventories are stated at the lower of cost (first-in, first-out or average) or market.
New Accounting Pronouncements	In May 2017, the FASB issued guidance to address the situation when a company modifies the terms of a stock compensation award previously granted to an employee. This guidance is effective, and should be applied prospectively, for fiscal years beginning after December 15, 2017. Early adoption is permitted as of the beginning of an annual period. The new guidance is effective for the Company beginning in fiscal 2019. The Company adopted this guidance as of October 1, 2018 and it did not have a material impact on the Company's financial condition, results of operations and related disclosures. In March 2017, the FASB issued amendments to the Compensation - Retirement Benefits guidance which requires companies to retrospectively present the service cost component of net periodic benefit cost for pension and retiree medical plans along with other compensation costs in operating income and present the other components of net periodic benefit cost below operating income in the income statement. The guidance also allows only the service cost component of net periodic benefit cost to be eligible for capitalization within inventory or fixed assets on a prospective basis. This guidance was effective for fiscal years beginning after December 15, 2017. The Company adopted the requirements of the standard in the first quarter of 2019 on a retrospective basis reclassifying the other components of the net periodic benefit costs from Selling, general and administrative expenses to a non-service expense within Other (income) expense, net. This guidance did not have a material impact on the Company's results of operations. See Note 13 - Employee Benefit Plans for further information on the implementation of this guidance. In January 2017, the FASB issued guidance that clarifies the definition of a business, which will impact many areas of accounting including acquisitions, disposals, goodwill, and consolidation. The new standard is intended to help companies and other organizations evaluate whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. This guidance is effective for annual periods beginning after December 15, 2017, including interim periods within those periods and will be effective for the Company beginning in fiscal 2019. The Company adopted the requirements of the standard in the first quarter of 2019 and it did not have a material impact on the Company's financial condition, results of operations and related disclosures. In August 2016, the FASB issued guidance on the Statement of Cash Flows Classification of certain cash receipts and cash payments (a consensus of the FASB Emerging Issues Task Force). This guidance addresses the following eight specific cash flow issues: Debt prepayment or debt extinguishment costs; settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing; contingent consideration payments made after a business combination; proceeds from the settlement of insurance claims; proceeds from the settlement of corporate-owned life insurance policies (including bank-owned life insurance policies); distributions received from equity method investees; beneficial interests in securitization transactions; and separately identifiable cash flows and application of the predominance principle. This guidance will be effective for the Company beginning in fiscal 2019. The Company adopted the requirements of the standard in the first quarter of 2019 and it did not have a material impact on the Company's financial condition, results of operations and cash flows. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) which supersedes nearly all existing revenue recognition guidance. Subsequent to the issuance of Topic 606, the FASB clarified the guidance through several ASUs; hereinafter the collection of revenue guidance is referred to as “ASC 606”. The core principle of ASC 606 is that revenue should be recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. On October 1, 2018, the Company adopted ASC 606 using the modified retrospective method for all contracts. Results for reporting periods beginning October 1, 2018 are presented under ASC 606, while prior period amounts were not adjusted and continue to be reported in accordance with the Company’s historic accounting under Topic 605, Revenue Recognition. The Company recorded a net increase to beginning retained earnings of approximately $5,673 as of October 1, 2018 due to the cumulative impact of adopting ASC 606. The impact to beginning retained earnings primarily related to certain contracts in the Defense Electronics Segment containing provisions for radar and communication products that have an alternative use and/or no right to payment. The adoption of ASC 606 did not have a material impact on the Company’s Consolidated Condensed Financial Statements as of and for the three month period ended December 31, 2018. See Note 3 - Revenue for additional disclosures required by ASC 606. Issued but not yet effective accounting pronouncements In February 2018, the FASB issued guidance that allows companies to reclassify stranded tax effects resulting from the 2017 Tax Cuts and Jobs Act (the Tax Act), from accumulated other comprehensive income to retained earnings. This guidance is effective for all entities for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years, with early adoption permitted. The new standard is effective for the Company beginning in 2020, with early adoption permitted. We are currently evaluating the effects that the adoption of this guidance will have on our consolidated financial statements and the related disclosures. In January 2017, the FASB issued guidance that simplifies how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit's goodwill with the carrying amount of that goodwill. This guidance is effective for annual periods beginning after December 15, 2019, including interim periods within those periods and will be effective for the Company beginning October 1, 2020. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. We are currently evaluating the impact of the guidance on the Company's financial condition, results of operations and related disclosures. 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 2020. We are currently evaluating the impact of the guidance on the Company's financial condition, results of operations and related disclosures.

As of December 31, 2018 , outstanding Senior Notes due totaled $1,000,000 ; interest is payable semi-annually on March 1 and September 1. The net proceeds of the $275,000 add-on offering were used to acquire ClosetMaid with the remaining proceeds used to pay down outstanding loan borrowings under Griffon's Revolving Credit Facility (the "Credit Agreement"). The net proceeds of the previously issued $125,000 add-on offering were used to pay down outstanding revolving loan borrowings under the Credit Agreement. The Senior Notes are senior unsecured obligations of Griffon guaranteed by certain domestic subsidiaries, and subject to certain covenants, limitations and restrictions. On February 5, 2018, July 20, 2016 and June 18, 2014, Griffon exchanged all of the $275,000 , $125,000 and $600,000 Senior Notes, respectively, for substantially identical Senior Notes registered under the Securities Act via an exchange offer. The fair value of the Senior Notes approximated $910,000 on December 31, 2018 based upon quoted market prices (level 1 inputs). In connection with the issuance and exchange of the $275,000 senior notes, Griffon capitalized $8,472 of underwriting fees and other expenses; in addition to the $13,329 capitalized under previously issued $600,000 Senior Notes. All capitalized fees for the Senior notes will amortize over the term of the notes and, at December 31, 2018 , $12,017 remained to be amortized. (b) On March 22, 2016, Griffon amended the Credit Agreement to increase the commitments under the credit facility 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. On October 2, 2017 and on May 31, 2018, Griffon amended the Credit Agreement in connection with the ClosetMaid and CornellCookson acquisitions, respectively, to among other things, modify the net leverage covenant. The facility includes a letter of credit sub-facility with a limit of $50,000 and a multi-currency sub-facility of $100,000 . The Credit Agreement provides for same day borrowings of base rate loans. Borrowings under the Credit Agreement may be repaid and re-borrowed at any time, subject to final maturity of the facility or the occurrence of an 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 1.75% for base rate loans and 2.75% 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 (c) below). At December 31, 2018 , under the Credit Agreement, there were $57,500 outstanding borrowings; outstanding standby letters of credit were $14,667 ; and $277,833 was available, subject to certain loan covenants, for borrowing at that date. (c) In September 2015 and March 2016, Griffon entered into mortgage loans in the amounts of $32,280 and $8,000 , respectively, and were due to mature in September 2025 and April 2018, respectively. The mortgage loans were secured and collateralized by four properties occupied by Griffon's subsidiaries and were guaranteed by Griffon. The loans had an interest rate of LIBOR plus 1.50% . The loans were paid off during the year ended September 30, 2018. (d) In August 2016, Griffon’s ESOP entered into an agreement that refinanced the existing ESOP loan into a new Term Loan in the amount of $35,092 (the "Agreement"). The Agreement also provided for a Line Note with $10,908 available to purchase shares of Griffon common stock in the open market. During 2017, Griffon's ESOP purchased 621,875 shares of common stock for a total of $10,908 or $17.54 per share, under a borrowing line that has now been fully utilized. On June 30, 2017, the Term Loan and Line Note were combined into a single Term Loan. The Term Loan bears interest at LIBOR plus 3.00% . The Term Loan requires quarterly principal payments of $569 with a balloon payment due at maturity on March 22, 2020. As a result of the special cash dividend of $1.00 per share, paid on April 16, 2018, the outstanding balance of the Term Loan was reduced by $5,705 . As of December 31, 2018 , $33,970 , 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. (e) Two Griffon subsidiaries have capital leases outstanding for real estate located in Troy, Ohio and Ocala, Florida. The leases mature in 2021 and 2022 , respectively, and bear interest at fixed rates of approximately 5.0% and 8.0% , respectively. The Troy, Ohio lease is secured by a mortgage on the real estate and is guaranteed by Griffon. The Ocala, Florida lease contains two five -year renewal options. At December 31, 2018 , $6,669 was outstanding, net of issuance costs. (f) In November 2012, Garant G.P. (“Garant”) entered into a CAD $15,000 ( $11,018 as of December 31, 2018 ) revolving credit facility. The facility accrues interest at LIBOR (USD) or the Bankers Acceptance Rate (CDN) plus 1.3% per annum ( 4.11% LIBOR USD and 3.50% Bankers Acceptance Rate CDN as of December 31, 2018 ). The revolving facility matures in October 2019. Garant is required to maintain a certain minimum equity. At December 31, 2018 , there were no borrowings under the revolving credit facility with CAD 15,000 ( $11,018 as of December 31, 2018) available for borrowing. In July 2016, Griffon Australia Holdings Pty Ltd and its Australian subsidiaries ("Griffon Australia") entered into an AUD 30,000 term loan and an AUD 10,000 revolver. The term loan refinanced two existing term loans and the revolver replaced two existing lines. In December 2016, the amount available under the revolver was increased from AUD 10,000 to AUD 20,000 and, in March 2017, the term loan commitment was increased by AUD 5,000 . In September 2017, the term commitment was increased by AUD 15,000 . The term loan requires quarterly principal payments of AUD 1,250 plus interest with a balloon payment of AUD 37,125 due upon maturity in October 2019, and accrues interest at Bank Bill Swap Bid Rate “BBSY” plus 2.00% per annum ( 4.11% at December 31, 2018 ). As of December 31, 2018, the term loan had an outstanding balance of AUD 39,625 ( $27,904 as of December 31, 2018 ). The revolving facility matures in March 2019, but is renewable upon mutual agreement with the lender, and accrues interest at BBSY plus 2.0% per annum ( 4.06% at December 31, 2018 ). At December 31, 2018, the revolver had an outstanding balance of AUD 20,000 ( $14,084 as of December 31, 2018). The revolver and the term loan are both secured by substantially all of the assets of Griffon Australia and its subsidiaries. Griffon guarantees the term loan. Griffon Australia is required to maintain a certain minimum equity level and is subject to a maximum leverage ratio and a minimum fixed charges cover ratio. In July 2018, the AMES Companies UK Ltd and its subsidiaries ("AMES UK") entered into a GBP 14,000 term loan, GBP 4,000 mortgage loan and GBP 5,000 revolver. The term loan and mortgage loan require quarterly principal payments of GBP 350 and GBP 83 plus interest, respectively, and have balloon payments due upon maturity, July 2023, of GBP 7,000 and GBP 2,333 , respectively. The Term Loan and Mortgage Loans accrue interest at the GBP LIBOR Rate plus 2.25% and 1.8% , respectively ( 3.16% and 2.71% at December 31, 2018, respectively). The revolving facility matures in July 2019, but is renewable upon mutual agreement with the lender, and accrues interest at the Bank of England Base Rate plus 1.5% ( 2.25% as of December 31, 2018). The revolver and the term loan are both secured by substantially all of the assets of AMES UK and its subsidiaries. AMES UK is subject to a maximum leverage ratio and a minimum fixed charges cover ratio. The invoice discounting arrangement was canceled and replaced by the above loan facilities. As of December 31, 2018, outstanding borrowings on these facilities totaled GBP 17,132 ( $21,669 as of December 31, 2018). (g) Other long-term debt consists primarily of a loan with the Pennsylvania Industrial Development Authority, with the balance consisting of capital leases. At December 31, 2018

As of December 31, 2018 , outstanding Senior Notes due totaled $1,000,000 ; interest is payable semi-annually on March 1 and September 1. The net proceeds of the $275,000 add-on offering were used to acquire ClosetMaid with the remaining proceeds used to pay down outstanding loan borrowings under Griffon's Revolving Credit Facility (the "Credit Agreement"). The net proceeds of the previously issued $125,000 add-on offering were used to pay down outstanding revolving loan borrowings under the Credit Agreement. The Senior Notes are senior unsecured obligations of Griffon guaranteed by certain domestic subsidiaries, and subject to certain covenants, limitations and restrictions. On February 5, 2018, July 20, 2016 and June 18, 2014, Griffon exchanged all of the $275,000 , $125,000 and $600,000 Senior Notes, respectively, for substantially identical Senior Notes registered under the Securities Act via an exchange offer. The fair value of the Senior Notes approximated $910,000 on December 31, 2018 based upon quoted market prices (level 1 inputs). In connection with the issuance and exchange of the $275,000 senior notes, Griffon capitalized $8,472 of underwriting fees and other expenses; in addition to the $13,329 capitalized under previously issued $600,000 Senior Notes. All capitalized fees for the Senior notes will amortize over the term of the notes and, at December 31, 2018 , $12,017 remained to be amortized. (b) On March 22, 2016, Griffon amended the Credit Agreement to increase the commitments under the credit facility 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. On October 2, 2017 and on May 31, 2018, Griffon amended the Credit Agreement in connection with the ClosetMaid and CornellCookson acquisitions, respectively, to among other things, modify the net leverage covenant. The facility includes a letter of credit sub-facility with a limit of $50,000 and a multi-currency sub-facility of $100,000 . The Credit Agreement provides for same day borrowings of base rate loans. Borrowings under the Credit Agreement may be repaid and re-borrowed at any time, subject to final maturity of the facility or the occurrence of an 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 1.75% for base rate loans and 2.75% 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 (c) below). At December 31, 2018 , under the Credit Agreement, there were $57,500 outstanding borrowings; outstanding standby letters of credit were $14,667 ; and $277,833 was available, subject to certain loan covenants, for borrowing at that date. (c) In September 2015 and March 2016, Griffon entered into mortgage loans in the amounts of $32,280 and $8,000 , respectively, and were due to mature in September 2025 and April 2018, respectively. The mortgage loans were secured and collateralized by four properties occupied by Griffon's subsidiaries and were guaranteed by Griffon. The loans had an interest rate of LIBOR plus 1.50% . The loans were paid off during the year ended September 30, 2018. (d) In August 2016, Griffon’s ESOP entered into an agreement that refinanced the existing ESOP loan into a new Term Loan in the amount of $35,092 (the "Agreement"). The Agreement also provided for a Line Note with $10,908 available to purchase shares of Griffon common stock in the open market. During 2017, Griffon's ESOP purchased 621,875 shares of common stock for a total of $10,908 or $17.54 per share, under a borrowing line that has now been fully utilized. On June 30, 2017, the Term Loan and Line Note were combined into a single Term Loan. The Term Loan bears interest at LIBOR plus 3.00% . The Term Loan requires quarterly principal payments of $569 with a balloon payment due at maturity on March 22, 2020. As a result of the special cash dividend of $1.00 per share, paid on April 16, 2018, the outstanding balance of the Term Loan was reduced by $5,705 . As of December 31, 2018 , $33,970 , 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. (e) Two Griffon subsidiaries have capital leases outstanding for real estate located in Troy, Ohio and Ocala, Florida. The leases mature in 2021 and 2022 , respectively, and bear interest at fixed rates of approximately 5.0% and 8.0% , respectively. The Troy, Ohio lease is secured by a mortgage on the real estate and is guaranteed by Griffon. The Ocala, Florida lease contains two five -year renewal options. At December 31, 2018 , $6,669 was outstanding, net of issuance costs. (f) In November 2012, Garant G.P. (“Garant”) entered into a CAD $15,000 ( $11,018 as of December 31, 2018 ) revolving credit facility. The facility accrues interest at LIBOR (USD) or the Bankers Acceptance Rate (CDN) plus 1.3% per annum ( 4.11% LIBOR USD and 3.50% Bankers Acceptance Rate CDN as of December 31, 2018 ). The revolving facility matures in October 2019. Garant is required to maintain a certain minimum equity. At December 31, 2018 , there were no borrowings under the revolving credit facility with CAD 15,000 ( $11,018 as of December 31, 2018) available for borrowing. In July 2016, Griffon Australia Holdings Pty Ltd and its Australian subsidiaries ("Griffon Australia") entered into an AUD 30,000 term loan and an AUD 10,000 revolver. The term loan refinanced two existing term loans and the revolver replaced two existing lines. In December 2016, the amount available under the revolver was increased from AUD 10,000 to AUD 20,000 and, in March 2017, the term loan commitment was increased by AUD 5,000 . In September 2017, the term commitment was increased by AUD 15,000 . The term loan requires quarterly principal payments of AUD 1,250 plus interest with a balloon payment of AUD 37,125 due upon maturity in October 2019, and accrues interest at Bank Bill Swap Bid Rate “BBSY” plus 2.00% per annum ( 4.11% at December 31, 2018 ). As of December 31, 2018, the term loan had an outstanding balance of AUD 39,625 ( $27,904 as of December 31, 2018 ). The revolving facility matures in March 2019, but is renewable upon mutual agreement with the lender, and accrues interest at BBSY plus 2.0% per annum ( 4.06% at December 31, 2018 ). At December 31, 2018, the revolver had an outstanding balance of AUD 20,000 ( $14,084 as of December 31, 2018). The revolver and the term loan are both secured by substantially all of the assets of Griffon Australia and its subsidiaries. Griffon guarantees the term loan. Griffon Australia is required to maintain a certain minimum equity level and is subject to a maximum leverage ratio and a minimum fixed charges cover ratio. In July 2018, the AMES Companies UK Ltd and its subsidiaries ("AMES UK") entered into a GBP 14,000 term loan, GBP 4,000 mortgage loan and GBP 5,000 revolver. The term loan and mortgage loan require quarterly principal payments of GBP 350 and GBP 83 plus interest, respectively, and have balloon payments due upon maturity, July 2023, of GBP 7,000 and GBP 2,333 , respectively. The Term Loan and Mortgage Loans accrue interest at the GBP LIBOR Rate plus 2.25% and 1.8% , respectively ( 3.16% and 2.71% at December 31, 2018, respectively). The revolving facility matures in July 2019, but is renewable upon mutual agreement with the lender, and accrues interest at the Bank of England Base Rate plus 1.5% ( 2.25% as of December 31, 2018). The revolver and the term loan are both secured by substantially all of the assets of AMES UK and its subsidiaries. AMES UK is subject to a maximum leverage ratio and a minimum fixed charges cover ratio. The invoice discounting arrangement was canceled and replaced by the above loan facilities. As of December 31, 2018, outstanding borrowings on these facilities totaled GBP 17,132 ( $21,669 as of December 31, 2018). (g) Other long-term debt consists primarily of a loan with the Pennsylvania Industrial Development Authority, with the balance consisting of capital leases. At December 31, 2018
