Organization, Consolidation and Presentation of Financial Statements [Abstract]
CONSOLIDATED FINANCIAL STATEMENTS	CONSOLIDATED FINANCIAL STATEMENTS The accompanying unaudited consolidated financial statements have been prepared by management in accordance with U.S. generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. In the opinion of management, all adjustments consisting of normal recurring adjustments considered necessary for the fair presentation of results for the interim period have been included. The results of operations for the three and nine month periods ended September 30, 2016 are not necessarily indicative of the results expected for the full year. The Company is subject to reduced activity in the first and fourth quarters as colder, inclement weather reduces order rates from end markets it serves. The accompanying unaudited consolidated financial statements should be read in conjunction with the financial statements and notes thereto included in our annual Form 10-K for the year ended December 31, 2015 . Immaterial Adjustments to Previously Reported Interim Periods In preparing its consolidated financial statements for the three and nine months ended September 30, 2016, the Company identified certain adjustments during the implementation and subsequent testing of internal controls over financial reporting, including internal controls over revenue recognition for the acquired company that closed in 2015. The Company determined that these identified adjustments should be made to previously reported interim periods within the Company's Renewable Energy and Conservation segment. These adjustments are a result of deficiencies and errors in the Company's accounting for estimated total contract costs at completion as it is related to revenue recognition under the percentage of completion accounting method. Specifically, beginning in the first quarter of 2016, the Company identified cost savings from margin improvement initiatives which included raw material sourcing, freight management, and strategic make versus buy decisions. These costs savings were incurred sooner than expected. They should have been reflected in the total estimated contract costs at completion for the quarters ended March 31, 2016 and June 30, 2016, which resulted in an understatement of revenue recorded for these respective quarters. In accordance with ASC Topic 250, Accounting Changes and Error Corrections, and Staff Accounting Bulletin No. 99, Materiality, the Company assessed these adjustments and determined that they were immaterial to each of the reporting periods affected and, therefore, amendment of previously filed reports was not required. However, the cumulative effect of correcting these errors would have been material to the results of our operations for the quarter ended September 30, 2016. Therefore, in order to provide consistency in the consolidated financial statements, adjustments for these immaterial amounts to previously reported interim period amounts are reflected in the financial information herein, and will be reflected in future filings containing such financial information. In accordance with ASC Topic 250, the effect of the correction on each financial statement line item, income from continuing operations, net income and related per-share amounts for each prior interim periods of the current fiscal year is as follows (in thousands, except per share data): For the Three Months Ended March 31, 2016 As Previously Reported Adjustments As Restated Net sales $ 233,677 $ 3,994 $ 237,671 Gross profit $ 50,156 $ 3,994 $ 54,150 Income from operations $ 13,607 $ 3,994 $ 17,601 Income from continuing operations $ 10,111 $ 3,994 $ 14,105 Provision for income taxes $ 3,618 $ 1,458 $ 5,076 Net income $ 6,493 $ 2,536 $ 9,029 Net earnings per share - Basic $ 0.21 $ 0.08 $ 0.29 Net earnings per share - Diluted $ 0.20 $ 0.08 $ 0.28 For the Three Months Ended June 30, 2016 As Previously Reported Adjustments As Restated Net sales $ 263,099 $ 2,639 $ 265,738 Gross profit $ 66,204 $ 2,639 $ 68,843 Income from operations $ 25,777 $ 2,639 $ 28,416 Income from continuing operations $ 14,076 $ 2,639 $ 16,715 Provision for income taxes $ (2,913 ) $ 1,016 $ (1,897 ) Net income $ 16,989 $ 1,623 $ 18,612 Net earnings per share - Basic $ 0.54 $ 0.05 $ 0.59 Net earnings per share - Diluted $ 0.53 $ 0.05 $ 0.58 For the Six Months Ended June 30, 2016 As Previously Reported Adjustments As Restated Net sales $ 496,776 $ 6,633 $ 503,409 Gross profit $ 116,360 $ 6,633 $ 122,993 Income from operations $ 39,384 $ 6,633 $ 46,017 Income from continuing operations $ 24,187 $ 6,633 $ 30,820 Provision for income taxes $ 705 $ 2,474 $ 3,179 Net income $ 23,482 $ 4,159 $ 27,641 Net earnings per share - Basic $ 0.75 $ 0.13 $ 0.88 Net earnings per share - Diluted $ 0.74 $ 0.13 $ 0.87 The tables below depict the effect of the correction for the Renewable Energy and Conservation segment on net sales and income from operations for each prior interim periods of the current fiscal year as follows (in thousands): For the Three Months Ended March 31, 2016 As Previously Reported Adjustments As Restated Net sales $ 53,880 $ 3,994 $ 57,874 Income from operations $ 4,313 $ 3,994 $ 8,307 For the Three Months Ended June 30, 2016 As Previously Reported Adjustments As Restated Net sales $ 62,127 $ 2,639 $ 64,766 Income from operations $ 7,657 $ 2,639 $ 10,296 For the Six Months Ended June 30, 2016 As Previously Reported Adjustments As Restated Net sales $ 116,007 $ 6,633 $ 122,640 Income from operations $ 11,970 $ 6,633 $ 18,603 There were no adjustments made to retained earnings at the beginning of 2016 as the effects of the adjusted amounts were to interim periods during the current fiscal year ending December 31, 2016.

Recent Accounting Pronouncement

Recent Accounting Pronouncements (Notes)	9 Months Ended

Accounting Policies [Abstract]
RECENT ACCOUNTING PRONOUNCEMENTS	RECENT ACCOUNTING PRONOUNCEMENTS In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-09, "Revenue from Contracts with Customers (Topic 606)." The update clarifies the principles for recognizing revenue and develops a common standard for U.S. Generally Accepted Accounting Principles and International Financial Reporting Standards. More specifically, the core principle of the guidance is that an entity should recognize revenue 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. In August 2015, the FASB issued ASU 2015-14 which deferred the effective date of Topic 606 to annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. In March 2016, the FASB issued ASU 2016-08, “Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net).” ASU 2016-08 clarifies the implementation guidance on principal versus agent considerations. In April 2016, the FASB issued ASU 2016-10, “Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing.” ASU 2016-10 clarifies the implementation guidance on identifying performance obligations. In May 2016, the FASB issued ASU 2016-12, "Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients." ASU 2016-12 reduces the potential for diversity among initial application, as well as, the cost and complexity of applying Topic 606 at transition and on an ongoing basis. These ASUs apply to all companies that enter into contracts with customers to transfer goods or services. These ASUs are effective for public entities for interim and annual reporting periods beginning after December 15, 2017. Early adoption is permitted, but not before interim and annual reporting periods beginning after December 15, 2016. Entities have the choice to apply these ASUs either retrospectively to each reporting period presented or by recognizing the cumulative effect of applying these standards at the date of initial application and not adjusting comparative information. We are currently evaluating the requirements of these standards and have not yet determined the impact on our consolidated financial statements. In July 2015, the FASB issued ASU 2015-11, "Inventory (Topic 330)." The amendments to this Update were issued to change the measurement of inventory to the lower of cost and net realizable value. The guidance, which is effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years, may be applied prospectively and early adopted for the beginning of an interim or annual period. The Company is currently evaluating the impact of adopting the new standard which is not expected to have a material impact on our Balance Sheet or Statements of Operations. In February 2016, the FASB issued ASU 2016-02, "Leases (Topic 842)." ASU 2016-02 requires lessees to recognize a lease liability and a right-of-use asset on the balance sheet. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. We are currently evaluating the requirements of ASU 2016-02 and have not yet determined its impact on our consolidated financial statements. In March 2016, the FASB issued ASU 2016-09, "Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting." ASU 2016-09 simplifies the accounting for share-based payment award transactions including: income tax consequences, classification of awards as either equity or liabilities and classification on the statement of cash flows. ASU 2016-09 is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. Early adoption is permitted. We are currently evaluating the requirements of ASU 2016-09 and have not yet determined its impact on our consolidated financial statements. In May 2016, the FASB issued ASU 2016-11, "Revenue Recognition (Topic 605) and Derivatives and Hedging (Topic 815): Rescission of SEC Guidance Because of Accounting Standards Updates 2014-09 and 2014-16 Pursuant to Staff Announcements at the March 3, 2016 EITF Meeting.” ASU 2016-11 rescinds certain SEC Staff Observer comments codified in Topic 605, Revenue Recognition, and Topic 932, Extractive Activities-Oil and Gas. ASU 2016-11 is effective upon adoption of Topic 606. We are currently evaluating the requirements of ASU 2016-11 and have not yet determined its impact on our consolidated financial statements. In August 2016, the FASB issued ASU 2016-15, "Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments." ASU 2016-15 provides guidance on eight specific cash flow issues to reduce diversity in reporting. This Update is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. We are currently evaluating the requirements of ASU 2016-15 and have not yet determined its impact on our consolidated financial statements.

Business Combinations [Abstract]
ACQUISITIONS	ACQUISITIONS On June 9, 2015, the Company acquired all of the outstanding stock of Rough Brothers Manufacturing, Inc., RBI Solar, Inc., and affiliates, collectively known as "RBI". RBI has established itself during the past seven years among North America's fastest-growing providers of racking and mounting systems for solar energy installations and is among the largest commercial greenhouse manufacturers in North America. RBI is a full service provider that engineers, manufactures and installs racking systems for solar power developers, contractors and companies. In addition, RBI designs, manufactures and erects greenhouses for commercial, institutional and retail customers. The results of RBI have been included in the Company’s consolidated financial results since the date of acquisition (within the Company's Renewable Energy and Conservation segment). The final aggregate purchase consideration for the acquisition of RBI was $147,585,000 , which includes payments for working capital and certain other adjustments provided for in the stock purchase agreement. The purchase price for the acquisition was allocated to the assets acquired and liabilities assumed based upon their respective fair values. The excess consideration of $57,180,000 , was recorded as goodwill of which $37,969,000 is deductible for tax purposes. The allocation of the purchase consideration to the fair value of the assets acquired and liabilities assumed is as follows as of the date of the acquisition (in thousands): Cash $ 4,651 Working capital 21,436 Property, plant, and equipment 12,797 Acquired intangible assets 56,392 Other assets 3,049 Deferred income taxes (4,892 ) Other liabilities (3,028 ) Goodwill 57,180 Fair value of purchase consideration $ 147,585 The Company recorded an indemnification asset and liability of $3.0 million on the opening balance sheet related to the seller’s obligation to fully indemnify the Company for the outcome of potential contingent liabilities related to uncertainty of income tax positions in foreign jurisdictions. The liability and related indemnification asset may or may not be realized, and any unrealized liability is scheduled to expire in 2018. The intangible assets acquired in this acquisition consisted of the following (in thousands): Fair Value Estimated Trademarks $ 13,550 Indefinite Technology 3,550 7-15 years Customer relationships 32,892 11-17 years Non-compete agreements 1,300 5 years Backlog 5,100 0.5 years Total $ 56,392 The acquisition was financed through cash on hand and borrowings under the Company's revolving credit facility. The Company incurred certain acquisition-related costs composed of legal and consulting fees, and these costs were recognized as a component of selling, general and administrative expenses in the consolidated statement of operations. The Company also recognized acquisition-related costs relating to the step-up of inventory to fair value which was a portion of the purchase price allocation of this acquisition.

Share-based Compensation [Abstract]
EQUITY-BASED COMPENSATION	EQUITY-BASED COMPENSATION On May 6, 2016, the shareholders of the Company authorized the Gibraltar Industries, Inc. 2016 Stock Plan for Non-Employee Directors ("Non-Employee Directors Plan"). The Non-Employee Directors Plan is a compensation plan that allows the Company to grant awards of shares of the Company's common stock to non-employee Directors of the Company. In connection with the Non-Employee Directors Plan, the Company adopted a new stock deferral plan, the Gibraltar Industries, Inc. Non-Employee Director Stock Deferral Plan ("Deferral Plan"). The Deferral Plan permits non-employee Directors of the Company to defer receipt of shares of common stock which the non-employee Director is entitled to receive pursuant to the terms of the Non-Employee Directors Plan. On May 7, 2015, the shareholders of the Company authorized the Gibraltar Industries, Inc. 2015 Equity Incentive Plan (the "Plan") and simultaneously amended the 2005 Equity Incentive Plan (the "Prior Plan") to terminate issuance of further awards from the Prior Plan. The Plan is an incentive compensation plan that allows the Company to grant equity-based incentive compensation awards to eligible participants. Awards under the Plan may be in the form of options, restricted shares, restricted units, performance shares, performance stock units, and rights. Equity Based Awards - Settled in Stock The following table provides the number of stock unit awards granted which will convert to shares upon vesting as well as restricted shares issued during the nine months ended September 30, along with the weighted average grant date fair values: 2016 2015 Awards Number of Awards Weighted Average Grant Date Fair Value Number of Awards Weighted Average Grant Date Fair Value Deferred stock units 11,945 $ 29.30 — $ — Restricted shares 3,185 $ 29.30 21,318 $ 17.48 Restricted stock units 139,982 $ 25.15 174,919 $ 16.13 Performance stock units — $ — 321,714 $ 18.46 Performance Stock Units - Settled in Cash The Company has also awarded performance stock units ("PSUs") that will convert to cash after three years based upon the one year performance period. The cost of these awards is recognized over the requisite vesting period. The PSUs earned over the performance period are determined based on the Company’s actual return on invested capital (ROIC) relative to the ROIC targeted for the performance period. The following table provides the number of PSUs which will convert to cash: 2016 2015 Awards Number of Units (1) Grant Date Fair Value (in $1000s) Number of Units (2) Performance stock units 128,000 $ 3,100 219,000 $ 4,039 (1) The final number of PSUs earned will be determined based upon actual performance at the end of 2016, with any amounts due to participants payable in January 2019. (2) The participants earned 200% of target, aggregating 438,000 PSUs earned. This award will convert to cash and be payable in January 2018. During the 2013 performance period, the participants earned an aggregate of 114,000 PSUs, representing 50% of the targeted award of 237,000 units. In January 2016, $2,723,000 was paid to the participants for the 2013 PSUs based on the trailing 90 -day closing price of the Company's common stock ended December 31, 2015 . No PSU awards were earned during the 2014 performance period. The following table summarizes the compensation expense recognized for the PSUs which will convert to cash for the three and nine months ended September 30, (in thousands): Three Months Ended Nine Months Ended 2016 2015 2016 2015 Performance stock unit compensation expense $ 4,148 $ 1,552 $ 7,889 $ 3,665 Management Stock Purchase Plan The Management Stock Purchase Plan ("MSPP") provides participants the ability to defer a portion of their compensation or Directors’ fees, which deferral is converted to restricted stock units, and credited to an account. Under the MSPP, the Company provides a matching award in restricted stock units equal to a percentage of the employees' compensation or Directors' 2015 fee deferral amount. Beginning January 1, 2016, Directors do not receive any company-matching on deferred fees. The account represents a share-based liability converted to and settled in cash which is payable to participants upon retirement or a termination of their service to the Company. The following table provides the number of restricted stock units credited to participant accounts and the payments made with respect to restricted stock units issued under the MSPP during the nine months ended September 30, 2016 2015 Restricted stock units credited 192,380 91,873 Share-based liabilities paid (in $1000s) $ 2,753 $ 1,686

DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES	DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES The Company is exposed to certain risks arising from both its business operations and economic conditions. The primary risks that the Company manages through its derivative instruments from time to time are foreign currency exchange rate risk and commodity pricing risk. We enter into derivative financial instruments with various financial institutions to minimize counterparty credit risk. Depending on the type of transaction, we may enter into either derivatives that are designated as hedging instruments and/or derivatives that are not designated as hedging instruments. As of September 30, 2016 , we do not currently hold any derivatives classified as hedging instruments and qualifying for hedge accounting. Derivatives not designated as hedging instruments To minimize foreign currency exposure, the Company had foreign currency forwards with notional amounts of $1,000,000 at September 30, 2016. These derivative instruments mature in March 2017. No foreign currency or commodity options were outstanding at September 30, 2016.

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Depending on the nature of the asset or liability, various techniques and assumptions can be used to estimate fair value. A financial asset or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement as follows: • Level 1 - Quoted prices in active markets for identical assets or liabilities. • Level 2 - Observable inputs other than quoted prices in active markets for similar assets and liabilities. • Level 3 - Inputs that are unobservable inputs for the asset or liability. The Company's derivatives are valued using various pricing models or discounted cash flow analyses that incorporate observable market data, such as interest rate yield curves, currency rates and implied volatility. In addition, the Company received fair value estimates from contract counterparties to verify the reasonableness of the Company's estimates. These derivatives are classified as Level 2 within the valuation hierarchy. The following table presents the fair values and classification of our financial assets (liabilities) measured on a recurring basis, all of which are classified as Level 2 (in thousands): Classification September 30, 2016 December 31, 2015 Foreign currency exchange options Other current assets $ — $ 1,792 Foreign currency exchange forwards Other current assets $ 1 $ — Foreign currency exchange forwards Accrued expenses $ — $ 14 The Company’s only other financial instrument for which the carrying value differs from its fair value is long-term debt. At September 30, 2016 and December 31, 2015 , the fair value of outstanding debt net of unamortized debt issuance costs was $221,410,000 and $217,925,000 , respectively, compared to its carrying value of $209,441,000 and $209,282,000 , respectively. The fair value of the Company’s Senior Subordinated 6.25% Notes is classified as Level 2 within the fair value hierarchy and was estimated based on quoted market prices adjusted for unamortized debt issuance costs.

Discontinued Operations and Disposal Groups [Abstract]
DIVESTITURE	DIVESTITURE In connection with the Company's strategy to drive transformational change in its portfolio and financial results, management continually evaluates all aspects of our current portfolio for future profitable growth and greater shareholder returns. As a result of this strategy, the Company sold its European industrial manufacturing business to a third party for cash of $9.1 million ( $8.3 million proceeds, net of transaction costs of $0.8 million ) on April 15, 2016. The sale of this business resulted in a loss before taxes of $8.8 million which is presented within other expense (income) in the consolidated Statement of Operations. As noted in the Income Taxes footnote, the Company recorded a discrete tax benefit of $11.5 million related to the sale, resulting in an after tax gain on sale of $2.7 million . This divestiture does not meet the criteria to be reported as a discontinued operation as it does not represent a strategic shift that has or will have a major effect on the Company's operations. Therefore, prior period results of continuing operations have not been restated to exclude the impact of the divested business's financial results. This business, which supplied expanded metal product for filtration, security perimeters and other applications, contributed $36 million in revenue to the Company's Industrial & Infrastructure Products segment for full year 2015 and had nearly break-even operating results.

Restructuring and Related Activities [Abstract]
EXIT ACTIVITY COSTS AND ASSET IMPAIRMENTS	EXIT ACTIVITY COSTS AND ASSET IMPAIRMENTS The Company’s business strategy has been formulated to effect a transformation of its operations and improve financial results over a five year period. In 2015, the first year of this planned transformation, an 80/20 simplification initiative commenced across many of our business units. This on-going initiative, in part, focuses the Company’s internal resources on further increasing the value provided to our customers. A result of this initiative was the identification of low-volume, internally-produced products which have been or will be outsourced or discontinued. During the nine months ended September 30, 2016 , charges resulted from this identification which relate to the write-down of inventory and impairment of machinery and equipment associated with either discontinued product lines or the reduction of manufactured goods offered within a product line. These assets were written down to their sale or scrap value, and were subsequently sold or disposed of. Exit activity costs were also incurred during the nine months ended September 30, 2016 which relate to contract termination costs, severance costs, and other moving and closing costs. These costs were the result of the closing and consolidation of facilities, relocation of inventory and equipment at those facilities and the reduction of workforce associated with the discontinued products and closed facilities. During the nine months ended September 30, 2015 , the Company closed three facilities and eliminated three product lines which resulted in asset impairment charges. In addition, the Company sold and leased back a fourth facility, which resulted in a gain. The following tables set forth the asset impairment charges, exit activity costs and gain on facilities sold in conjunction with these efforts, incurred by segment during the three and nine months ended September 30, related to the restructuring activities described above (in thousands): Three Months Ended 2016 2015 Inventory write-downs &/or asset impairment charges Exit activity costs Total Inventory write-downs &/or asset impairment charges Exit activity costs Total Residential Products $ 373 $ 207 $ 580 $ 502 $ 255 $ 757 Industrial & Infrastructure Products 2,429 756 3,185 — 8 8 Total exit activity costs & asset impairments $ 2,802 $ 963 $ 3,765 $ 502 $ 263 $ 765 Nine Months Ended 2016 2015 Inventory write-downs &/or asset impairment charges Exit activity costs Total Inventory write-downs &/or asset impairment charges Exit activity costs Gain on sale leaseback Total Residential Products $ 1,179 $ 677 $ 1,856 $ 3,247 $ 980 $ (6,799 ) $ (2,572 ) Industrial & Infrastructure Products 2,697 2,019 4,716 — 49 — 49 Total exit activity costs & asset impairments $ 3,876 $ 2,696 $ 6,572 $ 3,247 $ 1,029 $ (6,799 ) $ (2,523 ) The following table provides a summary of where the asset impairments and exit activity costs (gains) were recorded in the statement of operations for the three and nine months ended September 30, (in thousands): Three Months Ended Nine Months Ended 2016 2015 2016 2015 Cost of sales $ 3,433 $ 666 $ 5,111 $ 4,027 Selling, general, and administrative expense 332 99 1,461 (6,550 ) Net asset impairment and exit activity charges (gains) $ 3,765 $ 765 $ 6,572 $ (2,523 ) The following table reconciles the beginning and ending liability for exit activity costs relating to the Company’s facility consolidation efforts (in thousands): 2016 2015 Balance at January 1 $ 603 $ 575 Exit activity costs recognized 2,696 1,029 Cash payments (2,182 ) (1,083 ) Balance at September 30 $ 1,117 $ 521

Recent Accounting Pronouncements (Policies)	9 Months Ended

Accounting Policies [Abstract]
Recent Accounting Pronouncements	In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-09, "Revenue from Contracts with Customers (Topic 606)." The update clarifies the principles for recognizing revenue and develops a common standard for U.S. Generally Accepted Accounting Principles and International Financial Reporting Standards. More specifically, the core principle of the guidance is that an entity should recognize revenue 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. In August 2015, the FASB issued ASU 2015-14 which deferred the effective date of Topic 606 to annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. In March 2016, the FASB issued ASU 2016-08, “Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net).” ASU 2016-08 clarifies the implementation guidance on principal versus agent considerations. In April 2016, the FASB issued ASU 2016-10, “Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing.” ASU 2016-10 clarifies the implementation guidance on identifying performance obligations. In May 2016, the FASB issued ASU 2016-12, "Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients." ASU 2016-12 reduces the potential for diversity among initial application, as well as, the cost and complexity of applying Topic 606 at transition and on an ongoing basis. These ASUs apply to all companies that enter into contracts with customers to transfer goods or services. These ASUs are effective for public entities for interim and annual reporting periods beginning after December 15, 2017. Early adoption is permitted, but not before interim and annual reporting periods beginning after December 15, 2016. Entities have the choice to apply these ASUs either retrospectively to each reporting period presented or by recognizing the cumulative effect of applying these standards at the date of initial application and not adjusting comparative information. We are currently evaluating the requirements of these standards and have not yet determined the impact on our consolidated financial statements. In July 2015, the FASB issued ASU 2015-11, "Inventory (Topic 330)." The amendments to this Update were issued to change the measurement of inventory to the lower of cost and net realizable value. The guidance, which is effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years, may be applied prospectively and early adopted for the beginning of an interim or annual period. The Company is currently evaluating the impact of adopting the new standard which is not expected to have a material impact on our Balance Sheet or Statements of Operations. In February 2016, the FASB issued ASU 2016-02, "Leases (Topic 842)." ASU 2016-02 requires lessees to recognize a lease liability and a right-of-use asset on the balance sheet. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. We are currently evaluating the requirements of ASU 2016-02 and have not yet determined its impact on our consolidated financial statements. In March 2016, the FASB issued ASU 2016-09, "Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting." ASU 2016-09 simplifies the accounting for share-based payment award transactions including: income tax consequences, classification of awards as either equity or liabilities and classification on the statement of cash flows. ASU 2016-09 is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. Early adoption is permitted. We are currently evaluating the requirements of ASU 2016-09 and have not yet determined its impact on our consolidated financial statements.
