US Airways files tax returns in the U.S. federal jurisdiction, and in various states and foreign jurisdictions. All federal and state tax
filings for US Airways for fiscal years through December 31, 2009 have been timely filed. US Airways' federal income tax year 2006
was closed by operation of the statute of limitations expiring, and there were no extensions filed. There are currently no federal audits and
three state audits in process. US Airways files tax returns in 44 states, and its major state tax jurisdictions are Arizona, California,
Pennsylvania and North Carolina. Tax years up to 2005 for these state tax jurisdictions are closed by operation of the statute of
limitations expiring. Extensions for two states have been filed.
US Airways believes that its income tax filing positions and deductions related to tax periods subject to examination will be sustained
upon audit and does not anticipate any adjustments that will result in a material adverse effect on US Airways' financial condition, results
of operations, or cash flow. Therefore, no accruals for uncertain income tax positions have been recorded.
5. Risk Management and Financial Instruments
US Airways' economic prospects are heavily dependent upon two variables it cannot control: the health of the economy and the price
of fuel. Due to the discretionary nature of business and leisure travel spending, airline industry revenues are heavily influenced by the
condition of the U.S. economy and the economies in other regions of the world. Unfavorable economic conditions may result in
decreased passenger demand for air travel, which in turn could have a negative effect on US Airways' revenues. Similarly, the airline
industry may not be able to sufficiently raise ticket prices to offset increases in aviation jet fuel prices. These factors could impact
US Airways' results of operations, financial performance and liquidity.
