[1] Amounts include allowed claims (claims approved by the Bankruptcy Court) and estimated allowed claims relating to entry of orders treating as unsecured claims with respect to facility agreements supporting certain issuances of special facility revenue bonds. The Debtors record an estimated claim associated with the treatment of claims with respect to facility agreements when the applicable motion is filed with the Bankruptcy Court and the Debtors believe that it is probable that the motion will be approved, and there is sufficient information to estimate the claim. See above, “Rejection of Executory Contracts,” for further information.

[2] Pursuant to the Support Agreement, as defined and further described in Note 13 to the Condensed Consolidated Financial Statements, the Debtors agreed to allow certain post-petition unsecured claims on obligations. As a result, during the first six months of 2013, the Company recorded reorganization charges to adjust estimated allowed claim amounts previously recorded on rejected special facility revenue bonds of $143 million and allowed general unsecured claims related to the 1990 and 1994 series of special facility revenue bonds that financed certain improvements at John F. Kennedy International Airport, which is included in the table above.

[3] Amounts include allowed claims (claims approved by the Bankruptcy Court) and estimated allowed claims relating to the rejection or modification of financings related to aircraft. The Debtors record an estimated claim associated with the rejection or modification of a financing when the applicable motion is filed with the Bankruptcy Court to reject or modify such financing and the Debtors believe that it is probable the motion will be approved, and there is sufficient information to estimate the claim. Modifications of the financings related to certain aircraft remain subject to conditions, including reaching agreement on definitive documentation. See above, “Special Protection Applicable to Leases and Secured Financing of Aircraft and Aircraft Equipment,” for further information.
