Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION | DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION Description of Business Enphase Energy, Inc. and subsidiaries (the “Company”) delivers simple, innovative and reliable energy management solutions that advance the worldwide potential of renewable energy. Our semiconductor-based microinverter system converts direct current (DC) electricity to alternating current (AC) electricity at the individual solar module level, and brings a system-based, high technology approach to solar energy generation leveraging our design expertise across power electronics, semiconductors, networking, and cloud-based software technologies. Since inception, the Company has shipped more than 14 million microinverters, representing over 3 gigawatts of solar photovoltaic (PV) generating capacity, and more than 620,000 Enphase residential and commercial systems have been deployed in over 100 countries. Basis of Presentation and Consolidation The accompanying condensed consolidated financial statements are presented in accordance with accounting principles generally accepted in the U.S, or GAAP. The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. The Company disclosed in its Form 10-K for the year ended December 31, 2016 that certain conditions led it to conclude that substantial doubt existed as to the Company’s ability to continue as a going concern. The Company believes that the same or similar conditions continue to exist and that substantial doubt as to its ability to continue as a going concern within one year from the date of this filing also continues to exist. The accompanying consolidated financial statements for the three months ended March 31, 2017 are presented on a going concern basis and do not include any adjustments that might result from the outcome of this uncertainty. The Company has taken actions and intends to take further actions to improve its liquidity, including raising funds in the capital markets. In 2016, the Company completed a public offering of its common stock. The Company sold approximately 15 million shares and realized net proceeds of approximately $16.2 million . In December of 2016, the Company entered into an At The Market Issuance Sales Agreement (ATM) under which it may sell shares of common stock up to a gross aggregate offering price of $17.0 million . The Company realized the full gross proceeds of $17.0 million from common stock sold under the ATM during the three months ended March 31, 2017. In January 2017, the Company completed a private placement of securities that resulted in gross proceeds of $10.0 million . In July 2016, the Company entered into a loan and security agreement (the “Term Loan Agreement”) with lenders that are affiliates of Tennenbaum Capital Partners, LLC (collectively “TCP”). Under the agreement, the lenders committed to advance a term loan in an aggregate principal amount of up to $25.0 million with a maturity date of July 1, 2020. The Company drew down the $25.0 million term loan commitment at closing. In February 2017, the Company amended its loan and security agreement with TCP to provide an additional $25 million in principal. The Company simultaneously terminated its revolving credit facility with Wells Fargo Bank, N.A., and the combined principal and interest balance of $10.3 million was fully repaid. The amended loan has the same July 1, 2020 maturity date as the original TCP loan, both of which are interest only until February 2018. See Note 7, “Debt” for further information. The Company launched its next generation microinverter, the Enphase Home Energy Solution with IQ, in March 2017. This product is a major milestone in the Company’s product cost reduction initiative. The Company also introduced its AC Battery storage system in Australia in the third quarter of 2016 and in the U.S. and Europe in the fourth quarter of 2016. Actions the Company has taken to reduce its operating expenses include a reduction in its global workforce in the third quarter of 2016 and a second reduction in January 2017. The Company has eliminated certain projects that did not have a near-term return on investment, consolidated office space at its headquarters, divested its services business and engaged a management consulting firm to help it improve operational efficiencies. The Company expects the cumulative impact of these actions to decrease its ongoing annualized operating expenses by approximately $40 million as compared to pre-restructuring annualized operating expenses. For the three months ended March 31, 2017, the Company achieved a combined $9.0 million in savings for research and development, sales and marketing and general and administrative expenses over the same period in 2016, which was partially offset by increased restructuring charges of $7.2 million . Unaudited Interim Financial Information These accompanying unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) for interim financial reporting. In the opinion of management, these unaudited condensed consolidated financial statements reflect all adjustments, consisting of normal recurring items, considered necessary to present fairly the Company's financial condition, results of operations, comprehensive income (loss) and cash flows for the interim periods indicated. The results of operations for the three months ended March 31, 2017 are not necessarily indicative of the operating results for the full year. Certain information and footnote disclosures typically included in annual consolidated financial statements have been condensed or omitted. Accordingly, these unaudited interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016 . There have been no material changes in the Company’s significant accounting policies during the three months ended March 31, 2017 , as compared to the significant accounting policies described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016 . Reference is made to the disclosures therein for a summary of all of the Company’s significant accounting policies. Use of Estimates The preparation of financial statements in conformity with 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 income and expenses during the reporting period. Significant estimates and assumptions reflected in the financial statements include revenue recognition, inventory valuation and accrued warranty obligations. These estimates are based on information available as of the date of the financial statements; therefore, actual results could differ materially from management’s estimates using different assumptions or under different conditions. Recently Adopted Accounting Pronouncements In July 2015, the FASB issued ASU 2015-11, “Simplifying the Measurement of Inventory,” which requires most entities to measure most inventories at the lower of cost or net realizable value ("NRV"). This simplifies the evaluation from the current method of lower of cost or market, where market is based on one of three measures (i.e. replacement cost, net realizable value, or net realizable value less a normal profit margin). ASU 2015-11 does not apply to inventories measured under the last-in, first-out method or the retail inventory method, and defines NRV as the “estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation.” ASU 2015-11 is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. The adoption of this standard did not have a material impact on the consolidated financial statements. In March 2016, the FASB issued ASU 2016-09, “Improvements to Employee Share-Based Payment Accounting,” which will simplify the income tax consequences, accounting for forfeitures and classification on the Statements of Consolidated Cash Flows. ASU 2016-09 is effective for fiscal years and interim periods beginning after December 15, 2016, with early adoption permitted. The adoption of this standard did not have a material impact on the consolidated financial statements. Recently Issued Accounting Pronouncements Not Yet Effective In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, “Revenue from Contracts with Customers,” which will replace most existing revenue recognition guidance under U.S. GAAP. The updated standard’s core principle is that revenue is recognized when promised goods or services are transferred to customers in an amount that reflects the consideration to which an entity expects to be entitled in exchange for those goods or services. The standard generally requires an entity to identify performance obligations in its contracts, estimate the amount of variable consideration to be received in the transaction price, allocate the transaction price to each separate performance obligation, and recognize revenue as obligations are satisfied. In addition, the updated standard requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts. In 2015, the FASB issued guidance to defer the effective date to fiscal years beginning after December 15, 2017 with early adoption for fiscal years beginning December 15, 2016. The guidance permits the use of either a retrospective or cumulative effect transition method. In March 2016, the FASB issued ASU 2016-08, “Revenue from Contracts with Customers: Principal versus Agent Considerations (Reporting Revenue Gross versus Net),” which clarifies the guidance in ASU 2014-09 and has the same effective date as the original standard. During the three months ended June 30, 2016, the FASB issued ASU 2016-10, “Revenue from Contracts with Customers: Identifying Performance Obligations and Licensing”; ASU 2016-11, “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”; and ASU 2016-12, “Revenue from Contracts with Customers: Narrow-Scope Improvements and Practical Expedients.” These amendments are intended to improve and clarify the implementation guidance of ASU 2014-09 and have the same effective date as the original standard. The Company has not yet selected a transition method and is currently evaluating the impact of adoption on the consolidated financial statements. In January 2016, the FASB issued ASU 2016-01, “Recognition and Measurement of Financial Assets and Financial Liabilities,” which amends certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. Changes to the current guidance include the accounting for equity investments, the presentation and disclosure requirements for financial instruments, and the assessment of valuation allowance on deferred tax assets related to available-for-sale securities. In addition, ASU 2016-01 establishes an incremental recognition and disclosure requirement related to the presentation of fair value changes of financial liabilities for which the fair value option has been elected. Under this guidance, an entity would be required to separately present in other comprehensive income the portion of the total fair value change attributable to instrument-specific credit risk as opposed to reflecting the entire amount in earnings. ASU 2016-01 is effective for fiscal years and interim periods beginning after December 15, 2017, and upon adoption, an entity should apply the amendments by means of a cumulative-effect adjustment to the balance sheet at the beginning of the first reporting period in which the guidance is effective. Early adoption is not permitted except for the provision to record fair value changes for financial liabilities under the fair value option resulting from instrument-specific credit risk in other comprehensive income. The Company is currently evaluating the impact of adoption on the consolidated financial statements. |

Fair Value Disclosures [Abstract] | |
FAIR VALUE MEASUREMENTS | FAIR VALUE MEASUREMENTS The accounting guidance defines fair value as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities recorded at fair value, the Company considers the principal or most advantageous market in which it would transact and considers assumptions that market participants would use when pricing the asset or liability, such as inherent risk, transfer restrictions, and risk of nonperformance. The fair value hierarchy requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. An asset’s or liability’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. Three levels of inputs may be used to measure fair value: • Level 1—Valuations based on quoted prices in active markets for identical assets or liabilities that the Company is able to access. Since valuations are based on quoted prices that are readily and regularly available in an active market, valuation of such assets or liabilities do not entail a significant degree of judgment. • Level 2—Valuations based on one or more quoted prices in markets that are not active or for which all significant inputs are observable, either directly or indirectly. • Level 3—Valuations based on inputs that are unobservable and significant to the overall fair value measurement. The following table presents the Company’s liabilities that were measured at fair value on a recurring basis and its categorization within the fair value hierarchy at March 31, 2017 and December 31, 2016 (in thousands): Fair Value March 31, December 31, Liabilities: Warranty obligations Level 3 $ 11,627 $ 10,332 Fair Value Option for Warranty Obligations Related to Microinverters Sold Since January 1, 2014 The Company’s warranty obligations related to microinverters sold since January 1, 2014 provide the Company the right, but not the requirement, to assign its warranty obligations to a third-party. Under Accounting Standards Codification (“ASC”) 825—Financial Instruments, (“fair value option”), an entity may choose to elect the fair value option for such warranties at the time it first recognizes the eligible item. The Company made an irrevocable election to account for all eligible warranty obligations associated with microinverters sold since January 1, 2014 at fair value. This election was made to reflect the underlying economics of the time value of money for an obligation that will be settled over an extended period of up to 25 years. The Company estimates the fair value of warranty obligations by calculating the warranty obligations in the same manner as for sales prior to January 1, 2014 and applying an expected present value technique to that result. The expected present value technique, an income approach, converts future amounts into a single current discounted amount. In addition to the key estimates of failure rates, claim rates and replacement costs, the Company used certain Level 3 inputs which are unobservable and significant to the overall fair value measurement. Such additional assumptions included a discount rate based on the Company’s credit-adjusted risk-free rate and compensation comprised of a profit element and risk premium required of a market participant to assume the obligation. The following table provides information regarding changes in nonfinancial liabilities related to the Company’s warranty obligations measured at fair value on a recurring basis using significant unobservable inputs (Level 3) for the periods indicated (in thousands): Three Months Ended 2017 2016 Balance at beginning of period $ 10,332 $ 6,182 Accruals for warranties issued during period 830 695 Changes in estimates (266 ) (199 ) Settlements (342 ) (154 ) Increase due to accretion expense 495 384 Other 578 (419 ) Balance at end of period $ 11,627 $ 6,489 Quantitative and Qualitative Information about Level 3 Fair Value Measurements As of March 31, 2017 , the significant unobservable inputs used in the fair value measurement of the Company’s liabilities designated as Level 3 are as follows: Item Measured at Fair Value Valuation Technique Description of Significant Unobservable Input Percent Used (Weighted-Average) Warranty obligations for microinverters sold since January 1, 2014 Discounted cash flows Profit element and risk premium 17% Credit-adjusted risk-free rate 18% As of December 31, 2016 , the significant unobservable inputs used in the fair value measurement of the Company’s liabilities designated as Level 3 are as follows: Item Measured at Fair Value Valuation Technique Description of Significant Unobservable Input Percent Used (Weighted-Average) Warranty obligations for microinverters sold since January 1, 2014 Discounted cash flows Profit element and risk premium 17% Credit-adjusted risk-free rate 19% Sensitivity of Level 3 Inputs Warranty Obligations Each of the significant unobservable inputs is independent of the other. The profit element and risk premium are estimated based on requirements of a third-party participant willing to assume the Company’s warranty obligations. The credit-adjusted risk free rate (“discount rate”) is determined by reference to the Company’s own credit standing at the fair value measurement date. Increasing or decreasing the profit element and risk premium input by 100 basis points would not have a material impact on the fair value measurement of the liability. Increasing the discount rate by 100 basis points would result in a $0.5 million reduction of the liability. Decreasing the discount rate by 100 basis points would result in a $0.5 million increase to the liability. |

Short-term Debt [Abstract] | |
DEBT | DEBT Revolving Credit Facility The Company had a $50.0 million revolving credit facility with Wells Fargo Bank, N.A. (“Wells Fargo”) that was entered into in November 2012, as first amended on February 14, 2014. On December 18, 2015, the Company entered into an amended and restated revolving credit agreement with Wells Fargo (the “Revolver”) which extended the maturity date to November 7, 2019 and added an uncommitted accordion feature that could increase the size of the facility by $25.0 million , subject to the satisfaction of certain conditions. The Revolver was fully repaid and terminated in February 2017. Term Loan In July 2016, the Company entered into a Term Loan Agreement (the “Original Term Loan”) with lenders that are affiliates of Tennenbaum Capital Partners, LLC. (the “Lenders”). Under the agreement, the Lenders committed to advance a term loan in an aggregate principal amount of up to $25.0 million with a maturity date of July 1, 2020. The Company borrowed the entire $25.0 million of term loan commitments on the loan closing date. Monthly payments due through June 30, 2017 were interest only, followed by consecutive equal monthly payments of principal plus accrued interest that were to begin on July 1, 2017 and continue through the maturity date. The term loan provides for an interest rate per annum equal to the higher of (i) 10.25% or (ii) LIBOR plus 9.5625% , subject to a 1.0% reduction if the Company achieves minimum levels of Revenue and EBITDA (each as defined in the Term Loan Agreement) for the twelve-consecutive month period ending June 30, 2017 as set forth in the Term Loan Agreement. In addition, the Company paid a commitment fee of 3.3% of the loan amount upon closing and a closing fee of 10.0% of the loan amount is payable in four equal installments at each anniversary of the closing date. The Company may elect to prepay the loan by incurring a prepayment fee between 1% and 3% of the principal amount of the term loan depending on the timing and circumstances of prepayment. In February 2017, the Company entered into an Amended and Restated Loan and Security Agreement (the “Loan Agreement”) that amended and restated the Original Term Loan. The Loan Agreement provides for a $25.0 million secured term loan to the Company (the “New Term Loan”), which is in addition to the $25.0 million secured term loan borrowed by the Company under the Original Term Loan (together with the “New Term Loan” the “Term Loans”). The New Term Loan has the same July 1, 2020 maturity date that was applicable to the Original Term Loan. The New Term Loan was fully drawn at closing, with approximately $10.3 million of the proceeds used to repay existing combined principal and interest due under the Company’s Revolver with Wells Fargo. Upon the repayment of loans under the Wells Fargo Revolver, the Wells Fargo Revolving Credit Agreement was terminated. The Company expects to use the remainder of the proceeds from the New Term Loan for general corporate purposes. Monthly payments under the Term Loans through February 28, 2018 are interest only, followed by consecutive equal monthly payments of principal plus accrued interest beginning on March 1, 2018 and continuing through the maturity date; provided, however, that the Company may extend the interest only period on a month to month basis up to February 28, 2019 if no Event of Default (as defined in the Loan Agreement) has occurred and is continuing and the Company has Consolidated Operating Income (as defined in the Loan Agreement) for the calendar year 2017 and each month thereafter on a trailing twelve consecutive month basis of at least $15.0 million (collectively, the “Accommodation Conditions”). The Term Loans provide for an interest rate per annum equal to the greater of (i) 10.3125% and (ii) LIBOR plus 9.25% , subject to a 1.0% reduction if and for so long as the Accommodation Conditions have been met. In addition, the Company paid a commitment fee of 3.0% of the New Term Loan amount upon closing and a closing fee of 4.0% of the New Term Loan amount, which is payable with the closing fee under the Original Term Loan in four equal installments at each anniversary of the closing date of the Original Loan Agreement. The Company may elect to prepay the Term Loans by incurring a prepayment fee between 1% and 3% of the principal amount of the Term Loans depending on the timing and circumstances of prepayment. The Term Loans are secured by a first-priority security interest on substantially all assets of the Company; provided, however that the security interest in the Company’s intellectual property may be released if the Company satisfies certain requirements. The Company’s obligations under the Term Loans are not guaranteed by any of the Company’s existing subsidiaries, nor have any existing subsidiaries of the Company pledged any of their assets to secure the Term Loans. The Loan Agreement requires that (i) at all times from the closing date to and including March 31, 2018, the Company, and any future guarantors, have Unrestricted Cash (as defined in the Loan Agreement) of at least $10.0 million ; (ii) at all times from the closing date to and including March 31, 2018, that the aggregate amount of Consolidated Unrestricted Cash, plus the value of Consolidated Receivables, plus the value of Consolidated Inventory (each as defined in the Loan Agreement) divided by the outstanding principal amount of Term Loans, shall equal or exceed 1.5 ; and (iii) at all times from April 1, 2018 and thereafter, that the aggregate amount of Consolidated Unrestricted Cash, plus the value of Consolidated Receivables, plus the value of Consolidated Inventory divided by the outstanding principal amount of Term Loans, shall equal or exceed 1.75 . In addition, the Loan Agreement is subject to customary affirmative and negative covenants including restrictions on creation of liens, dispositions of assets, mergers, changing the nature of its business and dividends and other distributions, in each case subject to certain exceptions. The Term Loan Agreement also contains certain customary events of default including, but not limited to, failure to pay interest, principal and fees or other amounts when due, material breach of any representation or warranty, covenant defaults, cross defaults to other material indebtedness, events of bankruptcy and the occurrence of a material adverse change (as defined in the agreement) to the Company’s business. The Term Loan Agreement offers TCP typical rights and remedies in any event of default, including the ability to declare all amounts outstanding immediately due and payable. The Company was in compliance with all financial covenants as of March 31, 2017. In connection with the New Term Loan, the Company issued to the Lenders warrants to purchase an aggregate 1,220,000 shares of the Company’s Common Stock at an exercise price of $1.05 per share. The warrants have a term of seven years and contain a “cashless exercise” feature that allows the holder to exercise the warrant without a cash payment upon the terms set forth therein. The Company estimated the fair value of the warrants by using the Black-Scholes approach and the following assumptions: stock price of $1.56 ; strike price of $1.05 ; volatility of 85.9% , risk-free rate of 2.23% ; dividend yield of 0% ; and a 7 year term. The resulting fair value was used to allocate the proceeds from the Term Loan between liability and equity components. The Company classified the warrants as equity and allocated the proceeds from the Term Loan and warrants using the relative fair value method. Using this method, the Company allocated $1.4 million to the warrants, which was recorded as equity. This amount represents debt discount that will be amortized to interest expense over the term of the loan. Long-term debt was comprised of the following at March 31, 2017 and December 31, 2016 (in thousands): March 31, December 31, Term loan $ 50,000 $ 25,000 Less unamortized discount and issuance costs (3,119 ) (1,200 ) Carrying amount of debt 46,881 23,800 Less current portion (1,497 ) (3,032 ) Long-term debt $ 45,384 $ 20,768 As of March 31, 2017 , the amount of scheduled principal payments due on the term loan is as follows (in thousands): Year Amounts 2017 $ — 2018 15,229 2019 20,084 2020 14,687 Total $ 50,000 |

Income Tax Disclosure [Abstract] | |
INCOME TAXES | INCOME TAXES The Company used the discrete tax approach in calculating the tax expense for the three months ended March 31, 2017 and 2016 due to the fact that a relatively small change in the Company’s projected pre-tax net income (loss) could result in a volatile effective tax rate. Under the discrete method, the Company determines its tax (expense) benefit based upon actual results as if the interim period was an annual period. The tax provision recorded was primarily related to income taxes attributable to its foreign operations. |
NET LOSS PER SHARE

Earnings Per Share [Abstract] | |
NET LOSS PER SHARE | NET LOSS PER SHARE Basic net loss per share is computed by dividing net loss by the weighted average number of shares of common stock outstanding during the period. Diluted loss per share is computed in a similar manner, but it also includes the effect of potential common shares outstanding during the period, when dilutive. Potential common shares include outstanding in-the-money stock options, restricted stock units, shares to be purchased under the Company’s employee stock purchase plan and warrants to purchase common stock. The dilutive effect of potentially dilutive common shares is reflected in diluted earnings per share by application of the treasury stock method. To the extent these potential common shares are antidilutive, they are excluded from the calculation of diluted net loss per share. The following table presents the computation of basic and diluted net loss per share for the periods presented (in thousands, except per share data): Three Months Ended 2017 2016 Numerator: Net loss $ (23,305 ) $ (18,795 ) Denominator: Weighted average common shares outstanding 76,651 46,209 Net loss per share, basic and diluted $ (0.30 ) $ (0.41 ) As the Company incurred a net loss for all periods presented, potential dilutive securities from employee stock options, restricted stock units and warrants have been excluded from the diluted net loss per share computations because the effect of including such shares would have been anti-dilutive. The following table sets forth the potentially dilutive securities excluded from the computation of the diluted net loss per share (in thousands): Three Months Ended 2017 2016 Employee stock options 8,458 8,160 Restricted stock units 526 1,164 Warrants to purchase common stock 664 111 Total 9,648 9,435 |

Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
Basis of Presentation and Consolidation | Basis of Presentation and Consolidation The accompanying condensed consolidated financial statements are presented in accordance with accounting principles generally accepted in the U.S, or GAAP. The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. |
Unaudited Interim Financial Information | Unaudited Interim Financial Information These accompanying unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) for interim financial reporting. In the opinion of management, these unaudited condensed consolidated financial statements reflect all adjustments, consisting of normal recurring items, considered necessary to present fairly the Company's financial condition, results of operations, comprehensive income (loss) and cash flows for the interim periods indicated. The results of operations for the three months ended March 31, 2017 are not necessarily indicative of the operating results for the full year. Certain information and footnote disclosures typically included in annual consolidated financial statements have been condensed or omitted. Accordingly, these unaudited interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016 . |
Use of Estimates | Use of Estimates The preparation of financial statements in conformity with 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 income and expenses during the reporting period. Significant estimates and assumptions reflected in the financial statements include revenue recognition, inventory valuation and accrued warranty obligations. These estimates are based on information available as of the date of the financial statements; therefore, actual results could differ materially from management’s estimates using different assumptions or under different conditions. |
Recently Adopted Accounting Pronouncements and Recently Issued Accounting Pronouncements Not Yet Effective | Recently Adopted Accounting Pronouncements In July 2015, the FASB issued ASU 2015-11, “Simplifying the Measurement of Inventory,” which requires most entities to measure most inventories at the lower of cost or net realizable value ("NRV"). This simplifies the evaluation from the current method of lower of cost or market, where market is based on one of three measures (i.e. replacement cost, net realizable value, or net realizable value less a normal profit margin). ASU 2015-11 does not apply to inventories measured under the last-in, first-out method or the retail inventory method, and defines NRV as the “estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation.” ASU 2015-11 is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. The adoption of this standard did not have a material impact on the consolidated financial statements. In March 2016, the FASB issued ASU 2016-09, “Improvements to Employee Share-Based Payment Accounting,” which will simplify the income tax consequences, accounting for forfeitures and classification on the Statements of Consolidated Cash Flows. ASU 2016-09 is effective for fiscal years and interim periods beginning after December 15, 2016, with early adoption permitted. The adoption of this standard did not have a material impact on the consolidated financial statements. Recently Issued Accounting Pronouncements Not Yet Effective In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, “Revenue from Contracts with Customers,” which will replace most existing revenue recognition guidance under U.S. GAAP. The updated standard’s core principle is that revenue is recognized when promised goods or services are transferred to customers in an amount that reflects the consideration to which an entity expects to be entitled in exchange for those goods or services. The standard generally requires an entity to identify performance obligations in its contracts, estimate the amount of variable consideration to be received in the transaction price, allocate the transaction price to each separate performance obligation, and recognize revenue as obligations are satisfied. In addition, the updated standard requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts. In 2015, the FASB issued guidance to defer the effective date to fiscal years beginning after December 15, 2017 with early adoption for fiscal years beginning December 15, 2016. The guidance permits the use of either a retrospective or cumulative effect transition method. In March 2016, the FASB issued ASU 2016-08, “Revenue from Contracts with Customers: Principal versus Agent Considerations (Reporting Revenue Gross versus Net),” which clarifies the guidance in ASU 2014-09 and has the same effective date as the original standard. During the three months ended June 30, 2016, the FASB issued ASU 2016-10, “Revenue from Contracts with Customers: Identifying Performance Obligations and Licensing”; ASU 2016-11, “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”; and ASU 2016-12, “Revenue from Contracts with Customers: Narrow-Scope Improvements and Practical Expedients.” These amendments are intended to improve and clarify the implementation guidance of ASU 2014-09 and have the same effective date as the original standard. The Company has not yet selected a transition method and is currently evaluating the impact of adoption on the consolidated financial statements. In January 2016, the FASB issued ASU 2016-01, “Recognition and Measurement of Financial Assets and Financial Liabilities,” which amends certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. Changes to the current guidance include the accounting for equity investments, the presentation and disclosure requirements for financial instruments, and the assessment of valuation allowance on deferred tax assets related to available-for-sale securities. In addition, ASU 2016-01 establishes an incremental recognition and disclosure requirement related to the presentation of fair value changes of financial liabilities for which the fair value option has been elected. Under this guidance, an entity would be required to separately present in other comprehensive income the portion of the total fair value change attributable to instrument-specific credit risk as opposed to reflecting the entire amount in earnings. ASU 2016-01 is effective for fiscal years and interim periods beginning after December 15, 2017, and upon adoption, an entity should apply the amendments by means of a cumulative-effect adjustment to the balance sheet at the beginning of the first reporting period in which the guidance is effective. Early adoption is not permitted except for the provision to record fair value changes for financial liabilities under the fair value option resulting from instrument-specific credit risk in other comprehensive income. The Company is currently evaluating the impact of adoption on the consolidated financial statements. |
