The document summarizes a letter received by Realogy Corporation alleging that the company's invitations to existing noteholders to participate in new second lien loans are not authorized and constitute various breaches. The letter asserts the invitations will be challenged and any security interests voided. Realogy believes the assertions are without merit and intends to defend itself, proceeding with the invitations as scheduled. The letter also threatens to pursue responsible parties for fiduciary duty and securities law violations.
