Net earnings are adjusted for purposes of this calculation to eliminate interest and amortization of debt issuance costs on the convertible debentures net of related income taxes. When the conversion of convertible debentures increases the earnings per share or reduces the loss per share, the effect on earnings is antidilutive. Under these circumstances the fully diluted net earnings or net loss per share is computed assuming no conversion of the convertible debentures. (2) On July 28, 1993, RLI Corp. issued $46 million in 6.0% convertible debentures which mature July 15, 2003. These debentures, unless previously redeemed, are convertible at the option of the holder at any time prior to maturity into RLI Corp. common stock at an adjusted conversion price of $26.00 per share, subject to adjustment in certain events.
