US Airways, Inc.
Notes to Consolidated Financial Statements — (Continued)
collateralizing certain counterparties to US Airways' fuel hedging transactions is included in short-term restricted cash. In addition, at
December 31, 2008, US Airways had $276 million in cash deposits held by counterparties to its fuel hedging transactions. Since the third
quarter of 2008, US Airways has not entered into any new transactions as part of its fuel hedging program due to the impact collateral
requirements could have on its liquidity resulting from the significant decline in the price of oil and counterparty credit risk arising from
global economic uncertainty.
Further declines in heating oil prices would result in additional collateral requirements with US Airways' counterparties, unrealized
losses on its existing fuel hedging derivative instruments and realized losses at the time of settlement of these fuel hedging derivative
instruments.
Cash, Cash Equivalents and Investments in Marketable Securities
US Airways invests available cash in money market securities and highly liquid debt instruments.
As of December 31, 2008, US Airways held auction rate securities totaling $411 million at par value, which are classified as
available for sale securities and noncurrent assets on US Airways' consolidated balance sheets. Contractual maturities for these auction
rate securities range from eight to 44 years, with 62% of US Airways' portfolio maturing within the next ten years, 10% maturing within
the next 20 years, 16% maturing within the next 30 years and 12% maturing thereafter through 2052. The interest rates are reset
approximately every 28 days, except one security for which the auction process is currently suspended. Current yields range from 1.76%
to 6.08%. With the liquidity issues experienced in the global credit and capital markets, all of US Airways' auction rate securities have
experienced failed auctions since August 2007. The estimated fair value of these auction rate securities no longer approximates par value.
However, US Airways has not experienced any defaults and continues to earn and receive interest at the maximum contractual rates. See
Note 6 for discussion on how US Airways determines the fair value of its investments in auction rate securities.
At December 31, 2007, the $411 million par value auction rate securities had a fair value of $353 million, a $58 million decline
from par. Of this decline in fair value, $48 million was deemed temporary and an unrealized loss in this amount was recorded to other
comprehensive income. US Airways concluded $10 million of the decline was an other than temporary impairment as a single security
with subprime exposure experienced a severe decline in fair value during the period. Accordingly, the $10 million impairment charge was
recorded to other nonoperating expense, net in the fourth quarter of 2007.
At December 31, 2008, the fair value of US Airways' auction rate securities was $187 million, representing a decline in fair value of
$166 million from December 31, 2007. The decline in fair value was caused by the significant deterioration in the financial markets in
2008. US Airways concluded that the 2008 decline in fair value of $166 million as well as the previously deemed temporary declines
recorded to other comprehensive income of $48 million were now other than temporary. US Airways' conclusion for the other than
temporary impairment was due to the length of time and extent to which the fair value has been less than cost for certain securities. All of
these securities have experienced failed auctions for a period greater than one year, and there has been no recovery in their fair value.
Accordingly, US Airways recorded $214 million in impairment charges in other nonoperating expense, net related to the other than
temporary impairment of its auction rate securities. US Airways continues to monitor the market for auction rate securities and consider
its impact (if any) on the fair value of its investments. If the current market conditions deteriorate further, US Airways may be required to
record additional impairment charges in other nonoperating expense, net in future periods.
Accounts Receivable
As of December 31, 2008, most of US Airways' receivables related to tickets sold to individual passengers through the use of major
credit cards or to tickets sold by other airlines and used by passengers on US Airways or its regional airline affiliates. These receivables
are short-term, mostly being settled within seven days after sale. Bad
