Earnings Per Share [Abstract] |
Discussion on convertible debt included in computation of earnings per share diluted | If the average market price of Vishay common stock is less than the effective conversion price of the convertible senior notes due 2030, no shares are included in the diluted earnings per share computation for the convertible senior notes due 2030. Pursuant to the indenture governing the convertible senior notes due 2030, Vishay will satisfy its conversion obligations by paying $1 cash per $1 principal amount of converted notes and settle any additional amounts due in cash and/or common stock. In connection with the issuance of the convertible senior notes due 2030, the Company entered into capped call transactions, which were not included in the calculation of diluted earnings per share as their effect would have been anti-dilutive. The capped calls are intended to reduce the potential dilution to the Company's common stock in the event that at the time of conversion of the convertible senior notes due 2030 the Company's common stock price exceeds the conversion price of the convertible senior notes due 2030.
