Organization, Consolidation and Presentation of Financial Statements [Abstract]
GENERAL	NOTE 1:- GENERAL a. SolarEdge Technologies, Inc. (the “Company”) and its subsidiaries design, develop, and sell an intelligent The Company and its subsidiaries sell their products worldwide through large distributors and electrical equipment wholesalers to smaller solar installers, as well as directly to large solar installers and Engineering, Procurement and Construction firms (“EPCs”). In July and October 2018, the Company completed the acquisitions ("Gamatronic Acquisition") of substantially all of the assets and activities of Gamatronic Electronic Industries Ltd. ("Gamatronic IL") and all of the outstanding shares of its wholly owned subsidiary Gamatronic (UK) Limited (“Gamatronic UK”), respectively. Both companies ("UPS Division") are providers and manufacturers of Uninterruptible Power Supplies ("UPS") devices. On October 17, 2018, the Company completed the acquisition of 74.5% of the outstanding common shares and voting rights of Kokam Co., Ltd. (“Kokam”), a Korean company whose shares are traded on the Korean OTC market, a provider of Lithium-ion cells, batteries and energy storage solutions. From October 17, 2018 and through September 30, 2019 (unaudited), the Company increased its shareholdings of Kokam to 94.3%. On January 24, 2019, the Company completed the acquisition of 56.8% of the outstanding common shares and voting rights of S.M.R.E S.p.A (“SMRE”), an Italian company whose shares were traded on the Italian AIM, a provider of innovative integrated powertrain technology and electronics for electric vehicles. Between January 24, 2019 and September 30, 2019 (unaudited), the Company increased its shareholdings of SMRE to 99.8% (see Note 2). b. New accounting pronouncements not yet effective: In January 2017, the FASB issued ASU 2017-04, "Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment". ASU 2017-04 was issued to simplify how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. The amendments in ASU 2017-04 are effective for fiscal years, and interim periods within those years, beginning after December 15, 2019. The Company is in the process of evaluating the potential impact of this pronouncement. SOLAREDGE TECHNOLOGIES, INC. AND ITS SUBSIDIARIES NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) U.S. dollars in thousands (except share and per share data) NOTE 1:- GENERAL (Cont.) In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. ASU 2016-13 amends the impairment model to utilize an expected loss methodology in place of the currently used incurred loss methodology, which will result in a more timely recognition of losses. The Company will adopt Topic 326 effective January 1, 2020. The Company is currently assessing the impact that adopting this new accounting standard will have on its consolidated balance sheets, statements of income and cash flows. c. Recently issued and adopted pronouncements: In February 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update No. 2016-02 (Topic 842) "Leases". Topic 842 supersedes the lease requirements in Accounting Standards Codification (ASC) Topic 840, "Leases". Under Topic 842, lessees are required to recognize assets and liabilities on the balance sheet for most leases and provide enhanced disclosures. ASU No. 2016-02 is effective for interim and annual reporting periods beginning after December 15, 2018. In July 2018, the FASB issued amendments in ASU 2018-11, which provide a transition election to not restate comparative periods for the effects of applying the new standard. This transition election permits entities to change the date of initial application to the beginning of the earliest comparative period presented, or retrospectively at the beginning of the period of adoption through a cumulative-effect adjustment. The Company has elected to apply the standard retrospectively at the beginning of the period of adoption through a cumulative-effect adjustment. The Company has also elected certain relief options offered in ASU 2016-02 including certain available transitional practical expedients. The Company adopted Topic 842 effective January 1, 2019. The interim consolidated financial statements for the nine months ended September 30, 2019 are presented under the new standard, while the comparative periods are not adjusted and continue to be reported in accordance with the Company’s historical accounting policy (See Note 7). d. Basis of Presentation: The accompanying unaudited interim consolidated interim financial statements have been prepared in accordance with Article 10 of Regulation S-X, “Interim Financial Statements” and the rules and regulations for Form 10-Q of the Securities and Exchange Commission (the “SEC”). Pursuant to those rules and regulations, the Company has condensed or omitted certain information and disclosures in footnotes that it normally includes in its annual consolidated financial statements prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”). In management’s opinion, the Company has made all adjustments (consisting only of normal, recurring adjustments, except as otherwise indicated) necessary to fairly present its condensed consolidated financial position, results of operations, and cash flows. The Company’s interim period operating results do not necessarily indicate the results that may be expected for any other interim period or for the full fiscal year. The significant accounting policies applied in the annual consolidated financial statements of the Company as of December 31, 2018, contained in the Company’s Annual Report on Form 10-K filed with the SEC on February 28, 2019, have been applied consistently in these unaudited interim consolidated financial statements, except for the adoption of ASU No. 2016-02, “Leases (Topic 842) (see Note 1c). SOLAREDGE TECHNOLOGIES, INC. AND ITS SUBSIDIARIES NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) U.S. dollars in thousands (except share and per share data) NOTE 1:- GENERAL (Cont.) The Company depends primarily on one contract manufacturer and several limited or single source component suppliers, and is in the process of opening an additional site with this contract manufacturer and its own manufacturing site. Reliance on these vendors makes the Company vulnerable to possible capacity constraints and reduced control over component availability, delivery schedules, manufacturing yields, and costs.
