Description of Business and Bas

Description of Business and Basis of Presentation	9 Months Ended
	Sep. 25, 2015
Accounting Policies [Abstract]
Description of Business and Basis of Presentation	1. Description of Business and Basis of Presentation Description of Business Jason Industries, Inc. (“Jason Industries”), including its subsidiaries (collectively, the “Company”), is a diversified industrial manufacturing company with four reportable segments: seating, finishing, acoustics, and components. The segments have separate management teams and have operations within the United States and 14 foreign countries. The Company is a producer of seating for the motorcycle and off-road vehicle sectors, and a supplier of static seats to the commercial and residential lawn/turf sector. The Company is also a producer of non-woven acoustical fiber insulation for the automotive sector and a global manufacturer of industrial consumables (brushes, buffing wheels, buffing compounds, and abrasives). The Company also manufactures precision components, expanded and perforated metal, and slip-resistant walking surfaces. The Company was originally incorporated in Delaware on May 31, 2013 as a blank check company, formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination. On June 30, 2014 (the “Closing Date”), the Company consummated its business combination with Jason Partners Holdings Inc. (“Jason”) pursuant to the stock purchase agreement, dated as of March 16, 2014, which provided for the acquisition of all of the capital stock of Jason by the Company (the “Business Combination”). In connection with the closing of the Business Combination, the Company changed its name from Quinpario Acquisition Corp. to Jason Industries, Inc. and commenced trading of its common stock and warrants under the symbols, “JASN” and “JASNW”, respectively, on NASDAQ. See Note 2 for a further discussion of the Business Combination. Basis of Presentation The accompanying unaudited condensed consolidated financial statements of the Company have been prepared in accordance with generally accepted accounting principles for interim financial reporting and Article 10 of Regulation S-X. Accordingly, certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted pursuant to such rules and regulations, although the Company believes that the disclosures are adequate to make the information presented not misleading. For additional information, including the Company’s significant accounting policies, these condensed consolidated financial statements should be read in conjunction with the financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014. As a result of the Business Combination, the Company was identified as the acquirer for accounting purposes, and Jason is the acquiree and accounting predecessor. The Company’s financial statement presentation distinguishes a “Predecessor” for Jason for periods prior to the Closing Date. The Company was subsequently re-established as Jason Industries, Inc. and is the “Successor” for periods after the Closing Date, which includes the consolidation of Jason subsequent to the Business Combination on June 30, 2014. The acquisition was accounted for as a business combination using the acquisition method of accounting, and the Successor financial statements reflect a new basis of accounting that is based on the fair value of net assets acquired. See Note 2 for further discussion of the Business Combination. As a result of the application of the acquisition method of accounting as of the effective date of the acquisition, the financial statements for the Predecessor period and for the Successor period are presented on a different basis and, therefore, are not comparable. The Company’s fiscal year ends on December 31 . Throughout the year, the Company reports its results using a fiscal calendar whereby each three month quarterly reporting period is approximately thirteen weeks in length, ending on a Friday. The exceptions are the first quarter, which begins on January 1 , and the fourth quarter, which ends on December 31 . For 2015 , the Company’s fiscal quarters are comprised of the three months ending March 27 , June 26 , September 25 and December 31 . In 2014 , the Company’s fiscal quarters were comprised of the three months ended March 28 , June 27 , September 26 and December 31 . In the opinion of management, all adjustments considered necessary for a fair statement of financial results have been made. Such adjustments consist of only those of a normal recurring nature. Interim results are not necessarily indicative of the results that may be expected for the entire fiscal year. Recently issued accounting standards In September 2015, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update (“ASU”) 2015-16, “Simplifying the Accounting for Measurement Period Adjustments” (“ASU 2015-16”). ASU 2015-16 requires an acquirer to recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. ASU 2015-16 is effective for interim and annual periods beginning after December 15, 2016. Early application is permitted and should be applied prospectively. In August 2015, the FASB issued ASU 2015-15, “Presentation and Subsequent Measurement of Debt Issuance Costs Association with Line of Credit Arrangements” (“ASU 2015-15”). ASU 2015-15 indicates that previously issued guidance did not address presentation or subsequent measurement of debt issuance costs related to line of credit arrangements. Given the absence of authoritative guidance, the SEC staff has indicated that they would not object to an entity deferring and presenting debt issuance costs as assets and amortizing the deferred costs ratably over the term of the line of credit arrangement, regardless of whether there are any outstanding borrowings on the line of credit arrangement. The guidance is effective for annual reporting periods beginning after December 15, 2015, but early adoption is permitted. Management is evaluating the provisions of this statement and has not determined what impact the adoption of ASU 2015-15 will have on the Company’s financial position or results of operations. In July 2015, the FASB issued ASU 2015-11, “Simplifying the Measurement of Inventory” (“ASU 2015-11”). Under ASU 2015-11, inventory will be measured at the “lower of cost and net realizable value” and options that currently exist for “market value” will be eliminated. ASU 2015-11 defines net realizable value as the “estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation.” No other changes were made to the current guidance on inventory measurement. ASU 2015-11 is effective for interim and annual periods beginning after December 15, 2016. Early application is permitted and should be applied prospectively. Management is evaluating the provisions of this statement and has not determined what impact the adoption of ASU 2015-11 will have on the Company's financial position or results of operations.

Business Combinations [Abstract]
Consummation of Business Combination	2. Consummation of Business Combination On June 30, 2014 , the Company and Jason completed the Business Combination in which JPHI Holdings Inc. (“JPHI”), a majority owned subsidiary of the Company, acquired 100 percent of the capital stock of Jason. The purchase price of $536.0 million was funded by the cash proceeds from the Company’s initial public offering, new debt, the issuance of 45,000 shares of 8% Series A Convertible Perpetual Preferred Stock (the “Series A Preferred Stock”) and rollover equity invested by Jason’s former owners and management of Jason (collectively the “Rollover Participants”).

The principal amount of the First Lien Term Loans amortizes in quarterly installments equal to $0.8 million , with the balance payable at maturity. At the Company’s election, the interest rate per annum applicable to the loans under the Senior Secured Credit Facilities is based on a fluctuating rate of interest determined by reference to either (i) a base rate determined by reference to the higher of (a) the “prime rate” of Deutsche Bank AG New York Branch, (b) the federal funds effective rate plus 0.50% and (c) the Eurocurrency rate applicable for an interest period of one month plus 1.00% , plus an applicable margin equal to (x) 3.50% in the case of the First Lien Term Loans, (y) 2.25% in the case of the Revolving Credit Facility or (z) 7.00% in the case of the Second Lien Term Loans or (ii) a Eurocurrency rate determined by reference to LIBOR, adjusted for statutory reserve requirements, plus an applicable margin equal to (x) 4.50% in the case of the First Lien Term Loans, (y) 3.25% in the case of the Revolving Credit Facility or (z) 8.00% in the case of the Second Lien Term Loans. Borrowings under the First Lien Term Facility and Second Lien Term Facility are subject to a floor of 1.00% in the case of Eurocurrency loans. The applicable margin for loans under the Revolving Credit Facility may be subject to adjustment based upon Jason Incorporated’s consolidated first lien net leverage ratio. Under the Revolving Credit Facility, if the aggregate outstanding amount of all Revolving Loans, swingline loans and certain letter of credit obligations exceeds 25 percent of the revolving credit commitments at the end of any fiscal quarter, Jason Incorporated and its restricted subsidiaries will be required to not exceed a consolidated first lien net leverage ratio, initially specified at 5.50 to 1.00 , with periodic decreases beginning on July 1, 2016 to 5.25 to 1.00 , and decreasing to 4.50 to 1.00 on December 31, 2017 and remaining at that level thereafter.

The Company recognizes compensation expense based on estimated grant date fair values for all share-based awards issued to employees and directors, including restricted stock units and performance share units, which are restricted stock units with vesting conditions contingent upon achieving certain performance goals. Share based compensation expense is reported in selling and administrative expenses in the Company’s condensed consolidated statements of operations. There were 3,473,435 shares of common stock reserved and authorized for issuance under the 2014 Plan. At September 25, 2015 , 560,787 shares of common stock remain authorized and available for future grant under the 2014 Plan. The Company recognized the following share-based compensation expense: Successor Three Months Ended September 25, 2015 Nine Months Ended September 25, 2015 June 30, 2014 Through September 26, 2014 Compensation Expense: Restricted Stock Units $ 776 $ 2,356 $ 785 Adjusted EBITDA Vesting Awards 551 1,984 708 Stock Price Vesting Awards 184 1,247 570 1,511 5,587 2,063 Impact of accelerated vesting (1) — 876 — Total share-based compensation expense $ 1,511 $ 6,463 $ 2,063 Total income tax benefit recognized $ 404 $ 2,121 $ 800 (1) Represents the impact of the acceleration of certain vesting schedules for restricted stock units and stock price vesting awards related to the transition of the Company’s CFO. As of September 25, 2015 , total unrecognized compensation cost related to share-based compensation awards was approximately $9.1 million , net of estimated forfeitures, which the Company expects to recognize over a weighted average period of approximately 1.6 years. The following table sets forth the restricted and performance share unit activity: Restricted Stock Units Adjusted EBITDA Vesting Awards Stock Price Vesting Awards Units Weighted-Average Grant-Date Fair Value Units Weighted-Average Grant-Date Fair Value Units Weighted-Average Grant-Date Fair Value Nonvested at December 31, 2014 762,075 $ 10.50 1,215,704 $ 10.49 810,469 $ 3.54 Granted 186,827 6.79 91,178 7.70 60,785 1.08 Vested (306,820 ) 10.49 — — — — Forfeited (17,367 ) 10.49 (166,620 ) 10.49 (20,262 ) 3.54 Nonvested at September 25, 2015 624,715 $ 9.39 1,140,262 $ 10.27 850,992 $ 3.36 Restricted Stock Units As of September 25, 2015 , there was $4.4 million of unrecognized share-based compensation expense, which is expected to be recognized over a weighted-average period of 1.6 years. In connection with the vesting of RSUs previously issued by the Company, a number of shares sufficient to fund statutory minimum tax withholding requirements was withheld from the total shares issued or released to the award holder (under the terms of the 2014 Plan, the shares are considered to have been issued and are not added back to the pool of shares available for grant). During the three and nine months ended September 25, 2015 , 71,684 shares and 108,155 shares, respectively, with an aggregate value of $0.4 million and $0.7 million , respectively, were withheld to satisfy the requirement. The withholding is treated as a reduction in additional paid-in capital in the accompanying condensed consolidated statements of shareholders’ equity. Performance Share Units Adjusted EBITDA Vesting Awards Compensation expense for cumulative Adjusted EBITDA based performance share unit awards is currently being recognized based on an estimated payout of 100% of target or 753,421 shares.

Earnings Per Share [Abstract]
Earnings per Share	10. Earnings per Share Basic income (loss) per share is calculated by dividing net income (loss) attributable to Jason Industries’ common shareholders by the weighted average number of common shares outstanding for the period. In computing dilutive income (loss) per share, basic income (loss) per share is adjusted for the assumed issuance of all potentially dilutive share-based awards, including warrants, restricted stock units, performance share units, convertible preferred stock, and Rollover Shares of JPHI convertible into shares of Jason Industries. The reconciliation of the numerator and denominator of the basic and diluted income (loss) per share calculation and the anti-dilutive shares is as follows: Successor Predecessor Three Months Ended September 25, 2015 Nine Months Ended September 25, 2015 June 30, 2014 Through September 26, 2014 June 28, 2014 Through June 29, 2014 January 1, 2014 Through June 29, 2014 Net (loss) income per share attributable to Jason Industries common shareholders Basic and diluted income (loss) per share $ (0.16 ) $ (0.31 ) $ (0.41 ) $ (17,928 ) $ (4,955 ) Numerator: Net (loss) income available to common shareholders of Jason Industries $ (3,539 ) $ (6,801 ) $ (9,045 ) $ (17,928 ) $ (4,955 ) Denominator: Basic and diluted weighted-average shares outstanding 22,161 22,056 21,991 1 1 Weighted average number of anti-dilutive shares excluded from denominator: Warrants to purchase Jason Industries common stock 13,994 13,994 13,994 — — Conversion of Series A 8% Perpetual Convertible Preferred 3,653 3,653 3,653 — — Conversion of JPHI Rollover Shares convertible to Jason Industries common stock 3,486 3,486 3,486 — — Restricted stock units 734 611 762 — — Performance share units 1,604 1,555 2,026 — — Total 23,471 23,299 23,921 — — Warrants are considered anti-dilutive and excluded when the exercise price exceeds the average market value of the Company’s common stock price during the applicable period. Performance share units are considered anti-dilutive if the performance targets upon which the issuance of the shares are contingent have not been achieved and the respective performance period has not been completed as of the end of the current period. Due to losses available to the Company’s common shareholders for each of the periods presented, potentially dilutive shares are excluded from the diluted net loss per share calculation because they were anti-dilutive under the treasury stock method, in accordance with ASC Topic 260.

Income Taxes	11. Income Taxes At the end of each three month period, the Company estimates a base effective tax rate expected for the full year based on the most recent forecast of its pre-tax income, permanent book and tax differences, and global tax planning strategies. The Company uses this base rate to provide for income taxes on a year-to-date basis, excluding the effect of significant, unusual, discrete or extraordinary items, and items that are reported net of their related tax effects. The Company records the tax effect of significant, unusual, discrete or extraordinary items, and items that are reported net of their tax effects in the period in which they occur. The effective income tax rate was 36.4 %, and 37.9% for the three months ended September 25, 2015, and the successor period June 30, 2014 through September 26, 2014, respectively. The effective income tax rate was 28.0% for the nine months ended September 25, 2015. The effective income tax rate for 2015 reflects the benefits of tax losses at the higher U.S. Federal statutory rate and taxable earnings derived in foreign jurisdictions with tax rates that are lower than the U.S. Federal statutory rate, and discrete items. Net discrete tax expense was immaterial for the three months ended September 25, 2015 and the period June 30, 2014 through September 26, 2014. Net discrete tax expense for the nine months ended September 25, 2015 was impacted by $0.3 million due to the vesting of restricted stock units for which no tax benefit will be realized and $0.3 million due to non-deductible transaction costs in foreign subsidiaries for which no tax benefit was recognized. The amount of gross unrecognized tax benefits was $3.1 million and $2.7 million at September 25, 2015 and December 31, 2014, respectively. Of the $3.1 million of unrecognized tax benefits, $1.4 million would reduce the Company’s effective tax rate if recognized. During the next twelve months, the Company does not expect any significant changes in its unrecognized tax benefits. The Company recognizes interest and penalties related to tax matters in tax expense. The Company did not have any interest or penalties that were recognized as a component of the income tax provision at September 25, 2015 and December 31, 2014.

Segment Reporting [Abstract]
Business Segments, Geographic and Customer Information	13. Business Segments, Geographic and Customer Information The Company identifies its segments using the “management approach,” which designates the internal organization that is used by management for making operating decisions and assessing performance as the source of the Company’s reportable segments. The Company has four reportable segments: seating, finishing, acoustics and components. Net sales information relating to the Company’s reportable segments is as follows: Successor Predecessor Three Months Ended September 25, 2015 Nine Months Ended September 25, 2015 June 30, 2014 Through September 26, 2014 June 28, 2014 Through June 29, 2014 January 1, 2014 Through June 29, 2014 Net sales Seating $ 37,198 $ 140,067 $ 32,385 $ — $ 104,878 Finishing 52,339 141,835 45,181 — 96,692 Acoustics 51,755 158,728 54,033 — 109,930 Components 29,882 93,958 29,569 — 65,651 $ 171,174 $ 534,588 $ 161,168 $ — $ 377,151 The Company uses “Adjusted EBITDA” as the primary measure of profit or loss for the purposes of assessing the operating performance of its segments. The Company defines EBITDA as net income (loss) before interest expense, provision (benefit) for income taxes, depreciation and amortization and (gain)/loss on disposal of property, plant and equipment. The Company defines Adjusted EBITDA as EBITDA, excluding the impact of non-cash or non-operational losses or gains, including long-lived asset impairment charges, integration and other operational restructuring charges, transactional legal fees, other professional fees and special employee bonuses, purchase accounting adjustments, sponsor fees and expenses, and non-cash share based compensation expense. Management believes that Adjusted EBITDA provides a clear picture of the Company’s operating results by eliminating expenses and income that are not reflective of the underlying business performance. Certain corporate-level administrative expenses such as payroll and benefits, incentive compensation, travel, marketing, accounting, auditing and legal fees and certain other expenses are kept within its corporate results and not allocated to its business segments. Adjusted EBITDA is used to facilitate a comparison of the Company’s operating performance on a consistent basis from period to period and to analyze the factors and trends affecting its segments. The Company’s internal plans, budgets and forecasts use Adjusted EBITDA as a key metric. In addition, this measure is used to evaluate its operating performance and segment operating performance and to determine the level of incentive compensation paid to its employees. As the Company uses Adjusted EBITDA as its primary measure of segment performance, generally accepted accounting principles in the United States of America (“US GAAP”) on segment reporting require the Company to include this measure in its discussion of segment operating results. The Company must also reconcile Adjusted EBITDA to operating results presented on a US GAAP basis. Adjusted EBITDA information relating to the Company’s reportable segments is presented below followed by a reconciliation of total segment Adjusted EBITDA to consolidated income before taxes: Successor Predecessor Three Months Ended September 25, 2015 Nine Months Ended September 25, 2015 June 30, 2014 Through September 26, 2014 June 28, 2014 Through June 29, 2014 January 1, 2014 Through June 29, 2014 Segment Adjusted EBITDA Seating $ 2,904 $ 20,175 $ 3,568 $ — $ 17,668 Finishing 7,223 20,261 5,496 201 13,732 Acoustics 7,014 19,206 4,287 — 9,676 Components 5,211 15,913 1,716 (690 ) 10,324 $ 22,352 $ 75,555 $ 15,067 $ (489 ) $ 51,400 Interest expense (587 ) (1,376 ) (528 ) — (1,269 ) Depreciation and amortization of intangible assets (11,594 ) (33,361 ) (10,341 ) — (12,796 ) (Loss) gain on disposal of property, plant and equipment - net (8 ) 14 — — (336 ) Restructuring (923 ) (3,637 ) (103 ) — (2,554 ) Transaction-related expenses — (789 ) (18 ) — (242 ) Integration and other restructuring costs (1,421 ) (1,625 ) (7,587 ) — (2,575 ) Gain from sale of joint ventures — — — — 3,508 Total segment income (loss) before income taxes 7,819 34,781 (3,510 ) (489 ) 35,136 Corporate general and administrative expenses (3,791 ) (12,812 ) (1,491 ) — (7,032 ) Corporate interest expense (7,409 ) (22,044 ) (7,280 ) (82 ) (6,032 ) Corporate depreciation (98 ) (217 ) (35 ) — (57 ) Corporate transaction-related expenses — (97 ) (1,386 ) (23,009 ) (27,541 ) Corporate loss on disposal of property, plant and equipment — — — — (2 ) Corporate share based compensation (1,511 ) (6,463 ) (2,063 ) — — Consolidated (loss) income before income taxes $ (4,990 ) $ (6,852 ) $ (15,765 ) $ (23,580 ) $ (5,528 ) Assets held by reportable segments is as follows: Successor September 25, 2015 December 31, 2014 Assets Seating $ 216,353 $ 219,215 Finishing 261,754 221,074 Acoustics 212,481 195,031 Components 129,805 137,354 Total segments 820,393 772,674 Corporate and eliminations 17,823 36,730 Consolidated $ 838,216 $ 809,404

Fair Value Disclosures [Abstract]
Fair Value Measurements	14. Fair Value Measurements Fair value of financial instruments Current accounting guidance defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants. It also specifies a fair value hierarchy based upon the observability of inputs used in valuation techniques. Observable inputs (highest level) reflect market data obtained from independent sources, while unobservable inputs (lowest level) reflect internally developed market assumptions. In accordance with the guidance, fair value measurements are classified under the following hierarchy: • Level 1 — Quoted prices for identical instruments in active markets. • Level 2 — Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs or significant value-drivers are observable in active markets. • Level 3 — Model-derived valuations in which one or more significant inputs or significant value-drivers are unobservable. Fair value measurements are classified according to the lowest level input or value-driver that is significant to the valuation. A measurement may therefore be classified within Level 3 even though there may be significant inputs that are readily observable. The carrying amounts within the accompanying condensed consolidated balance sheets for cash and cash equivalents, accounts receivable and accounts payable approximate fair value due to the short-term maturity of these instruments. The Company assessed the amounts recorded under revolving loans, if any, and long-term debt and determined that the fair value of total debt was approximately $440.5 million as of September 25, 2015 . As of December 31, 2014 , the fair value of total debt approximated its recorded value. The Company considers the inputs related to these estimations to be Level 2 fair value measurements as they are primarily based on quoted prices for the Company’s Senior Secured Credit Facility.

Commitments and Contingencies Disclosure [Abstract]
Litigation and Contingencies	15. Litigation and Contingencies The Company is a party to various legal proceedings that have arisen in the normal course of its business. These legal proceedings typically include product liability, labor, and employment claims. The Company has recorded reserves for loss contingencies based on the specific circumstances of each case. Such reserves are recorded when it is probable that a loss has been incurred as of the balance sheet date, can be reasonably estimated and is not covered by insurance. In the opinion of management, the resolution of these contingencies will not have a material adverse effect on the Company’s financial condition, results of operations, or cash flows. At September 25, 2015 and December 31, 2014 , the Company held reserves of $1.1 million for environmental matters at two locations. The ultimate cost of any remediation required will depend on the results of future investigation. Based upon available information, the Company believes that it has obtained and is in substantial compliance with those material environmental permits and approvals necessary to conduct its business. Based on the facts presently known, the Company does not expect environmental costs to have a material adverse effect on its financial condition, results of operations or cash flows.

Accounting Policies [Abstract]
Basis of presentation	The accompanying unaudited condensed consolidated financial statements of the Company have been prepared in accordance with generally accepted accounting principles for interim financial reporting and Article 10 of Regulation S-X. Accordingly, certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted pursuant to such rules and regulations, although the Company believes that the disclosures are adequate to make the information presented not misleading. For additional information, including the Company’s significant accounting policies, these condensed consolidated financial statements should be read in conjunction with the financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014. As a result of the Business Combination, the Company was identified as the acquirer for accounting purposes, and Jason is the acquiree and accounting predecessor. The Company’s financial statement presentation distinguishes a “Predecessor” for Jason for periods prior to the Closing Date. The Company was subsequently re-established as Jason Industries, Inc. and is the “Successor” for periods after the Closing Date, which includes the consolidation of Jason subsequent to the Business Combination on June 30, 2014. The acquisition was accounted for as a business combination using the acquisition method of accounting, and the Successor financial statements reflect a new basis of accounting that is based on the fair value of net assets acquired. See Note 2 for further discussion of the Business Combination. As a result of the application of the acquisition method of accounting as of the effective date of the acquisition, the financial statements for the Predecessor period and for the Successor period are presented on a different basis and, therefore, are not comparable. The Company’s fiscal year ends on December 31 . Throughout the year, the Company reports its results using a fiscal calendar whereby each three month quarterly reporting period is approximately thirteen weeks in length, ending on a Friday. The exceptions are the first quarter, which begins on January 1 , and the fourth quarter, which ends on December 31 . For 2015 , the Company’s fiscal quarters are comprised of the three months ending March 27 , June 26 , September 25 and December 31 . In 2014 , the Company’s fiscal quarters were comprised of the three months ended March 28 , June 27 , September 26 and December 31 . In the opinion of management, all adjustments considered necessary for a fair statement of financial results have been made. Such adjustments consist of only those of a normal recurring nature. Interim results are not necessarily indicative of the results that may be expected for the entire fiscal year.
Recently issued accounting standards	In September 2015, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update (“ASU”) 2015-16, “Simplifying the Accounting for Measurement Period Adjustments” (“ASU 2015-16”). ASU 2015-16 requires an acquirer to recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. ASU 2015-16 is effective for interim and annual periods beginning after December 15, 2016. Early application is permitted and should be applied prospectively. In August 2015, the FASB issued ASU 2015-15, “Presentation and Subsequent Measurement of Debt Issuance Costs Association with Line of Credit Arrangements” (“ASU 2015-15”). ASU 2015-15 indicates that previously issued guidance did not address presentation or subsequent measurement of debt issuance costs related to line of credit arrangements. Given the absence of authoritative guidance, the SEC staff has indicated that they would not object to an entity deferring and presenting debt issuance costs as assets and amortizing the deferred costs ratably over the term of the line of credit arrangement, regardless of whether there are any outstanding borrowings on the line of credit arrangement. The guidance is effective for annual reporting periods beginning after December 15, 2015, but early adoption is permitted. Management is evaluating the provisions of this statement and has not determined what impact the adoption of ASU 2015-15 will have on the Company’s financial position or results of operations. In July 2015, the FASB issued ASU 2015-11, “Simplifying the Measurement of Inventory” (“ASU 2015-11”). Under ASU 2015-11, inventory will be measured at the “lower of cost and net realizable value” and options that currently exist for “market value” will be eliminated. ASU 2015-11 defines net realizable value as the “estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation.” No other changes were made to the current guidance on inventory measurement. ASU 2015-11 is effective for interim and annual periods beginning after December 15, 2016. Early application is permitted and should be applied prospectively. Management is evaluating the provisions of this statement and has not determined what impact the adoption of ASU 2015-11 will have on the Company's financial position or results of operations.
