US Airways files tax returns in the U.S. federal jurisdiction, and in various states and foreign jurisdictions. As part of US Airways'
bankruptcy filings, the Internal Revenue Service and various state jurisdictions filed proofs of claim. Upon its emergence from
bankruptcy, US Airways had established reserves for all IRS claims and state income tax claims as of the date of the bankruptcy filing on
September 12, 2004. All creditors, including the IRS and state and local taxing jurisdictions, had to timely file a proof of claim to support
any tax deficiencies per the tax authority records. On February 15, 2007, US Airways and the IRS agreed to settle the IRS's outstanding
proofs of claim for $7 million.
All federal and state tax filings for US Airways and AWA for fiscal years through December 31, 2006 have been timely filed. There
are currently no federal or state audits in process. US Airways' last federal income tax audit closed all tax years through December 31,
2002. AWA's tax year 2002 was closed by operation of the statute of limitations expiring, and there were no extensions filed. US Airways
is not currently under examination.
