Earnings Per Share [Abstract]

Discussion on convertible debt included in computation of earnings per share diluted

The Company's convertible debt instruments are only convertible for specified periods upon the occurrence of certain events.  The Company's convertible debentures due 2040 became convertible subsequent to the December 31, 2020 evaluation of the conversion criteria.  In periods that the convertible debt instruments are not convertible, the certain conditions which could trigger conversion of the debt instruments have been deemed to be non-substantive, and accordingly, the Company assumes the conversion of these instruments in its diluted earnings per share computation during periods in which they are dilutive.

The Company, upon conversion, will repay the principal amounts of the convertible debt instruments in cash and settle any additional amounts in shares of Vishay common stock. Prior to the adoption of ASU No. 2020-06 on January 1, 2020, the convertible instruments are included in the diluted earnings per share computation using the “treasury stock method” (similar to options and warrants) rather than the “if converted method” otherwise required for convertible debt.  Under the “treasury stock method,” Vishay calculates the number of shares issuable under the terms of the convertible instruments based on the average market price of Vishay common stock during the period, and that number is included in the total diluted shares figure for the period.  If the average market price is less than $12.22, no shares are included in the diluted earnings per share computation for the convertible senior debentures due 2040 and if the average market price is less than $31.36 no shares are included in the diluted earnings per share computation for the convertible senior notes due 2025.
