Domain Name Registrar Business
On January 9, 2006, Network Solutions repaid in full all amounts outstanding under the Secured Senior Promissory Note dated November 25, 2003. In addition, Network Solutions redeemed our 15% equity interest in Network Solutions. We received approximately $47.8 million in total cash, which included the $26.5 million repayment of the note receivable and related interest and recognized a gain on investment of $21.3 million. As a result of the redemption of the membership interests, we no longer own equity interests in any Internet domain name registrars.
