Organization, Consolidation and Presentation of Financial Statements [Abstract]  
Organization and Basis of Presentation ORGANIZATION AND BASIS OF PRESENTATION
Organization. NovoCure Limited (including its consolidated subsidiaries, the "Company") was incorporated in the Bailiwick of Jersey and is principally engaged in the development, manufacture and commercialization of Tumor Treating Fields ("TTFields") delivery systems, including Optune and Optune Lua (collectively, our "Products"), for the treatment of solid tumor cancers. The Company currently markets Optune in the United States ("U.S."), Austria, Germany, Israel, Japan, Sweden and Switzerland. The Company currently markets Optune Lua in the U.S. The Company also has a License and Collaboration Agreement (the "Zai Agreement") with Zai Lab (Shanghai) Co., Ltd. ("Zai") to market Optune in Greater China.
Financial statement preparation. The accompanying unaudited consolidated financial statements include the accounts of the Company and intercompany accounts and transactions have been eliminated. In the opinion of the Company’s management, the consolidated financial statements reflect all adjustments, which are normal and recurring in nature, necessary for fair financial statement presentation for the periods presented. The preparation of these consolidated financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in these consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates. These consolidated financial statements and accompanying notes should be read in conjunction with the Company’s annual consolidated financial statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2020 (the "2020 10-K') filed with the Securities and Exchange Commission on February 25, 2021.
The significant accounting policies applied in the audited annual consolidated financial statements of the Company as disclosed in the 2020 10-K are applied consistently in these unaudited interim consolidated financial statements, except as noted below:
Recently Adopted Accounting Pronouncements.
In August 2020, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2020-06, Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity (ASU 2020-06), which simplifies the accounting for certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts in an entity’s own equity. Among other changes, ASU 2020-06 removes from GAAP the liability and equity separation model for convertible instruments with a cash conversion feature, and as a result, after adoption, entities will no longer separately present in equity an embedded conversion feature for such debt. Similarly, the embedded conversion feature will no longer be amortized into income as interest expense over the life of the instrument. Instead, entities will account for a convertible debt instrument wholly as debt unless (1) a convertible instrument contains features that require bifurcation as a derivative under ASC Topic 815, Derivatives and Hedging, or (2) a convertible debt instrument was issued at a substantial premium. Additionally, ASU 2020-06 requires the application of the if-converted method to calculate the impact of convertible instruments on diluted earnings per share (EPS), which is consistent with the Company’s accounting treatment under the current standard. ASU 2020-06 is effective for fiscal years beginning after December 15, 2021, with early adoption permitted for fiscal years beginning after December 15, 2020, and can be adopted on either a fully retrospective or modified retrospective basis. The Company early adopted ASU 2020-06, effective January 1, 2021 on a modified retrospective basis.
The impact of the Company’s adoption of ASU 2020-06 on the balance sheet as of January 1, 2021 was an increase in long term debt, net of $128,972, a decrease in additional paid-in capital of $132,474, and a decrease in accumulated deficit of $3,502. Interest expense recognized in future periods will be reduced as a result of accounting for the convertible debt instrument as a single liability measured at its amortized cost. For additional information see Note 5 of these unaudited consolidated financial statements.
In December 2019, the FASB issued Accounting Standard Update No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (ASU 2019-12), which simplifies the accounting for income taxes, eliminates certain exceptions within ASC 740, Income Taxes, and clarifies certain aspects of the current guidance. ASU 2019-12 is effective for the Company as of January 1, 2021 and the adoption of this standard did not have a material impact on the Company's consolidated financial statements.

Convertible Note CONVERTIBLE NOTE
On November 5, 2020, the Company issued $575,000 aggregate principal amount of 0% Convertible Senior Notes due 2025 (the “Notes”).
The Notes are senior unsecured obligations of the Company. The Notes do not bear regular interest, and the principal amount of the Notes will not accrete. Special interest, if any, payable in accordance with the terms of the Notes will be payable in cash semi-annually in arrears on May 1 and November 1 of each year, beginning on May 1, 2021. The Notes mature on November 1, 2025, unless earlier repurchased, redeemed or converted. For additional information, see Note 10(a) to the Consolidated Financial Statements in the 2020 10-K.
In January 2021, the Company irrevocably elected to settle all conversions of Notes by a combination of cash and the Company's ordinary shares and that the cash portion per $1,000 principal amount of Notes for all conversion settlements shall be $1,000. Accordingly, from and after the date of the election, upon conversion of any Notes, holders of Notes will receive, with respect to each $1,000 principal amount of Notes converted, cash in an amount up to $1,000 and the balance of the conversion value, if any, in ordinary shares (the "Conversion Shares").
The net carrying amount of the liability and equity components of the Notes as of March 31, 2021 and December 31, 2020 are as follows:

PSUs granted under the 2015 Plan generally vest between a three and six year period as performance targets are attained. RSUs and PSUs granted under the 2015 Plan that are canceled before expiration become available for future grants. As of March 31, 2021, 14,450,270 ordinary shares were available for grant under the 2015 Plan.

In September 2015, the Company adopted an employee share purchase plan (“ESPP”) to encourage and enable eligible employees to acquire ownership of the Company’s ordinary shares purchased through accumulated payroll deductions on an after-tax basis. In the United States, the ESPP is intended to be an “employee stock purchase plan” within the meaning of Section 423 of the Internal Revenue Code and the provisions of the ESPP are construed in a manner consistent with the requirements of such section. As of March 31, 2021, 5,006,367 ordinary shares were available to be purchased by eligible employees under the ESPP.
The fair value of share-based awards was estimated using the Black-Scholes model for all equity grants. For market condition awards, the Company also applied the Monte-Carlo simulation model. We assessed fair value using the following underlying assumptions:

Earnings Per Share [Abstract]  
Basic and Diluted Net Income (Loss) Per Ordinary Share Basic and diluted net income (loss) per ordinary shareBasic net income (loss) per share is computed based on the weighted average number of ordinary shares outstanding during each period. Diluted net income per share is computed based on the weighted average number of ordinary shares outstanding during the period, plus potential dilutive shares (deriving from options, RSUs, PSUs, convertible notes and the ESPP) considered outstanding during the period, in accordance with ASC 260-10, as determined under the if-converted method. The following table sets forth the computation of the Company’s basic and diluted net income (loss) per ordinary share:

Recently Adopted Accounting Pronouncements
Recently Adopted Accounting Pronouncements.
In August 2020, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2020-06, Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity (ASU 2020-06), which simplifies the accounting for certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts in an entity’s own equity. Among other changes, ASU 2020-06 removes from GAAP the liability and equity separation model for convertible instruments with a cash conversion feature, and as a result, after adoption, entities will no longer separately present in equity an embedded conversion feature for such debt. Similarly, the embedded conversion feature will no longer be amortized into income as interest expense over the life of the instrument. Instead, entities will account for a convertible debt instrument wholly as debt unless (1) a convertible instrument contains features that require bifurcation as a derivative under ASC Topic 815, Derivatives and Hedging, or (2) a convertible debt instrument was issued at a substantial premium. Additionally, ASU 2020-06 requires the application of the if-converted method to calculate the impact of convertible instruments on diluted earnings per share (EPS), which is consistent with the Company’s accounting treatment under the current standard. ASU 2020-06 is effective for fiscal years beginning after December 15, 2021, with early adoption permitted for fiscal years beginning after December 15, 2020, and can be adopted on either a fully retrospective or modified retrospective basis. The Company early adopted ASU 2020-06, effective January 1, 2021 on a modified retrospective basis.
The impact of the Company’s adoption of ASU 2020-06 on the balance sheet as of January 1, 2021 was an increase in long term debt, net of $128,972, a decrease in additional paid-in capital of $132,474, and a decrease in accumulated deficit of $3,502. Interest expense recognized in future periods will be reduced as a result of accounting for the convertible debt instrument as a single liability measured at its amortized cost. For additional information see Note 5 of these unaudited consolidated financial statements.
In December 2019, the FASB issued Accounting Standard Update No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (ASU 2019-12), which simplifies the accounting for income taxes, eliminates certain exceptions within ASC 740, Income Taxes, and clarifies certain aspects of the current guidance. ASU 2019-12 is effective for the Company as of January 1, 2021 and the adoption of this standard did not have a material impact on the Company's consolidated financial statements.
