Table of Contents unsecured claims with respect to facility agreements supporting certain issuances of special facility revenue bonds.
The Debtors recorded an estimated claim associated with the rejection or modification of a financing or facility agreement when the applicable motion was filed with the Bankruptcy Court to reject or modify such financing or facility agreement and the Debtors believed that it was probable the motion would be approved, and there was sufficient information to estimate the claim.
See Note 2 to AAG’s Consolidated Financial Statements in Part II, Item 8A for further information.
(3) Pursuant to the Plan, the Debtors agreed to allow certain post-petition unsecured claims on obligations.
As a result, during the year ended December 31, 2013, we recorded reorganization charges to adjust estimated allowed claim amounts previously recorded on rejected special facility revenue bonds of $180 million, allowed general unsecured claims related to the 1990 and 1994 series of special facility revenue bonds that financed certain improvements at JFK, and rejected bonds that financed certain improvements at ORD, which are included in the table above.
(4) The Plan allowed unsecured creditors receiving AAG Series A Preferred Stock a conversion discount of 3.5%.
Accordingly, we recorded the fair value of such discount upon the confirmation of the Plan by the Bankruptcy Court.

## Table 0 ##
(1) In 2013, other revenue special item, net included a credit to other revenues related to a change in accounting method resulting from the modification of American’s AAdvantage miles agreement with Citibank.
(2) In 2014, mainline operating special items, net principally included $527 million of Merger integration expenses related to information technology, alignment of labor union contracts, professional fees, severance
shares of Citigroup common stock.
The number of shares to be delivered will equal the CSE award value divided by the then fair market value of the common stock.
For CSEs awarded to certain employees whose compensation structure was approved by the Special Master, 50% of the shares to be delivered in April 2010 will be subject to restrictions on sale and transfer until January 20, 2011.
In lieu of 2010 CAP awards, certain retirement-eligible employees were instead awarded CSEs payable in April 2010, but any shares that are to be delivered in April 2010 (subject to stockholder approval) will be subject to restrictions on sale or transfer that will lapse in four equal annual installments beginning January 20, 2011.
CSE awards have generally been accrued as compensation expenses in the year 2009 and will be recorded as a liability from the January 2010 grant date until the settlement date in April 2010.
If stockholders approve delivery of Citigroup stock for the CSE awards, CSE awards will likely be paid as new issues of common stock as an exception to the Company’s practice of delivering shares from treasury stock, and the recorded liability will be reclassified as equity at that time.
In January 2009, members of the Management Executive Committee (except the CEO and CFO) received 30% of their incentive awards for 2008 as performance vesting-equity awards.
These awards vest 50% if the price of Citigroup common stock meets a price target of $10.61, and 50% for a price target of $17.85, in each case on or prior to January 14, 2013.
The price target will be met only if the NYSE closing price equals or exceeds the applicable price target for at least 20 NYSE trading days within any period of 30 consecutive NYSE trading days ending on or before January 14, 2013.
Any shares that have not vested by such date will vest according to a fraction, the numerator of which is the share price on the delivery date and the denominator of which is the price target of the unvested shares.
No dividend equivalents are paid on unvested awards.
Fair value of the awards is recognized as compensation expense ratably over the vesting period.
On July17, 2007, the Committee approved the Management Committee Long-Term Incentive Plan (MC LTIP) (pursuant to the terms of the shareholder-approved 1999 Stock Incentive Plan) under which participants received an equity award that could be earned based on Citigroup’s performance against various metrics relative to peer companies and publiclystated return on equity (ROE) targets measured at the end of each calendar year beginning with 2007.
The final expense for each of the three consecutive calendar years was adjusted based on the results of the ROE tests.
No awards were earned for 2009, 2008 or 2007 and no shares were issued because performance targets were not met.
No new awards were made under the MC LTIP since the initial award in July 2007.
CAP participants in 2008, 2007, 2006 and 2005, and FA CAP participants in those years and in 2009, could elect to receive all or part of their award in stock options.
The figures presented in the stock option program tables (see “Stock Option Programs” below) include options granted in lieu of CAP and FA CAP stock awards in those years.
A summary of the status of Citigroup’s unvested stock awards at December31, 2009 and changes during the 12 months ended December31, 2009 are presented below:
## Table 1 ##
(1) The weighted-average market value of the vestings during 2009 was approximately $3.64 per share.
At December31, 2009, there was $1.6 billion of total unrecognized compensation cost related to unvested stock awards net of the forfeiture provision.
That cost is expected to be recognized over a weighted-average period of 1.3 years.
Contributions The Company’s funding practice for U. S.  and non-U.
S.  pension and postretirement plans is generally to fund to minimum funding requirements in accordance with applicable local laws and regulations.
The Company may increase its contributions above the minimum required contribution, if appropriate.
In addition, management has the ability to change its funding practices.
For the U. S.  pension plans, there were no required minimum cash contributions for 2015 or 2014.
The following table summarizes the actual Company contributions for the years ended December 31, 2015 and 2014, as well as estimated expected Company contributions for 2016.
Expected contributions are subject to change since contribution decisions are affected by various factors, such as market performance and regulatory requirements.
