[1] For the purposes of determining this amount, the Effective Date is estimated to be in the first quarter of 2017; however this date is outside of our control and is highly subject to change.

[2] No amounts have been accrued because amounts are not a settlement of past actions, do not relate to any existing contingencies, and are not legally enforceable at this time. In addition, for certain items, CEC will receive valuable consideration in return and therefore these payments will not be expensed when incurred. We expect to accrue such items on or subsequent to the Effective Date.

[3] “OpCo” refers to the proposed entity resulting from the Restructuring that will operate the CEOC Properties under a lease with PropCo. “CEOC Properties” refers to those properties owned by CEOC as of the Petition Date. Holders of over 85% of the First Lien Notes have already indicated their intent to put their OpCo equity to CEC once received.

[4] “PropCo” refers to the proposed entity resulting from the Restructuring that will own the CEOC Properties as of the Effective Date.

[5] $86 million was paid in fourth quarter of 2015.

[6] Amount has not been accrued because CEOC currently has excess liquidity and is expected to maintain this position.

[7] $61 million was paid in fourth quarter of 2015.

[8] Amount payable on the Effective Date is subject to the excess cash held by CEOC at Emergence.

[9] Under the terms of the Initial Plan, CEC will pay amounts if certain classes of CEOC’s unsecured creditors vote in favor of the Initial Plan and if the Initial Plan is approved by the Bankruptcy Court.
