Settlement terms	Under the terms of the Settlement Agreement, which covers all individuals whose personal information was identified as being on the unaccounted-for server drives, class members who did not previously accept our offer of the credit monitoring and related services described above are eligible to receive such credit monitoring and related services for a period of two years at no cost to them. Class members who previously accepted our original offer are eligible to receive one additional year of such services. In addition, under the Settlement Agreement, class members are eligible to receive reimbursement for certain unreimbursed losses arising from identity theft during a specified time period, up to a cap of $50,000 per class member, and $2 million in the aggregate. The Settlement Agreement also provides that we will continue our ongoing activities to enhance our information security measures, including the encryption of data at rest on our servers and storage area networks. We are also responsible for the payment of the court's award of fees and expenses to plaintiffs' counsel in the amount of approximately $2.3 million. Finally, we will be responsible for the costs of administering the Settlement Agreement.
