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 upon the occurrence of certain events. While none of these events has occurred as of October 1, 2011, certain conditions which could trigger conversion have been deemed to be non-substantive, and accordingly, the Company has always assumed the conversion of these instruments in its diluted earnings per share computation during periods in which they are dilutive.
Discussion on convertible debt not included in computation of earnings per share diluted | At the direction of its Board of Directors, the Company intends, upon conversion, to repay the principal amounts of the convertible senior debentures, due 2040 and due 2041, in cash and settle any additional amounts in shares of Vishay common stock. Accordingly, the debentures 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 notes 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 $13.88, 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 $19.02, no shares are included in the diluted earnings per share computation for the convertible senior debentures due 2041. The Company purchased 99.6% of the outstanding convertible subordinated notes due 2023 pursuant to the option of the holders to require the Company to repurchase their notes on August 1, 2008. The remaining notes, with an aggregate principal amount of $1,870,000, were redeemed at Vishay’s option on August 1, 2010. The Company waived its rights to settle the principal amount of the convertible subordinated notes, due 2023, in shares of Vishay common stock. Accordingly, the notes were 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. If the average market price was less than $21.28, no shares were included in the diluted earnings per share computation. The convertible subordinated notes were anti-dilutive for the fiscal quarter and nine fiscal months ended October 2, 2010 and therefore are not included in the computation of diluted earnings per share.
