<div align="left" style="font-size: 10pt; margin-top: 6pt">     <i>Available-for-sale investment securities: </i>Included in our available-for-sale investment
securities are certificate of deposits placed through an account registry service, or CDARS, and
commercial paper with original maturities greater than 90 days but less than one year. At December
31, 2009, we also held asset backed securities, which are considered variable rate demand notes
with contractual maturities generally
greater than ten years with interest reset dates often every 30 days or less. The fair values
of these investments are based on observable market data. We did not record any significant gains
or losses on these securities during the six months ended June 30, 2010.
</div>
<div align="left" style="font-size: 10pt; margin-top: 6pt">     <i>Held-to-maturity investment securities: </i>During 2009 and the six months ended June 30, 2010, we
purchased various corporate bonds. Those with original maturities less than twelve months are
included in short-term investments on our condensed consolidated balance sheets, and those with
original maturities in excess of twelve months are included in long-term investments on our
condensed consolidated balance sheets. The fair value of these investments is based on observable
market data. We did not record any significant gains or losses on these securities during the six
months ended June 30, 2010.
</div>
<div align="left" style="font-size: 10pt; margin-top: 6pt">     <i>Auction rate securities</i>: At June 30, 2010, the fair values of our ARS all of which are
collateralized by student loan portfolios (substantially all of which are guaranteed by the United
States Government), were estimated through discounted cash flow models. Since these inputs were
not observable, they are classified as level 3 inputs. For the three months ended June 30, 2009,
we recorded an unrealized holding gain on our ARS of $8 million, based on the then current fair
value. We classify our ARS as trading securities and therefore measure at each reporting period
with the resulting gain (loss) recognized in other income (expense). Our discounted cash flow
analysis considered, among other things, the quality of the underlying collateral, the credit
rating of the issuers, an estimate of when these securities are either expected to have a
successful auction or otherwise return to par value, expected interest income to be received over
this period, and the estimated required rate of return for investors. Because of the inherent
subjectivity in valuing these securities, we also considered independent valuations obtained for
each of our ARS as of June 30, 2009 in estimating their fair values.
</div>
<div align="left" style="font-size: 10pt; margin-top: 6pt">     In July 2010,
the remaining $49 million par value of ARS were repurchased at par by UBS in
accordance with the settlement agreement with them as described more fully in
Note 14 of our 2009 Form 10-K. The proceeds were used to terminate the outstanding balance on the
line of credit with UBS.
</div>
<div align="left" style="font-size: 10pt; margin-top: 6pt">     <b><i>Put option related to ARS</i></b><i>: </i>We have elected to apply the fair value option under the Financial
Instruments topic of the Codification, to UBS’s agreement to repurchase, at par, ARS brokered by
them. We have done so in order to closely conform to our treatment of the underlying ARS. As of
June 30, 2010, the $7 million fair value of this put option is included in other current assets in
our condensed consolidated balance sheets. Any gain (loss) resulting from an adjustment of the
fair value is included in other income (expense). The change in fair value was insignificant
during the six months ended June 30, 2010 and 2009, respectively. The fair value of the put option
is based on unobservable inputs and is therefore classified as level 3 in the hierarchy.
</div>
<div align="left" style="font-size: 10pt; margin-top: 6pt">     <b><i>Interest Rate Swaps</i></b><i>: </i>The fair values of our interest rate swaps are initially based on inputs
received from the counterparty. These values were corroborated by adjusting the active swap
indications in quoted markets for similar terms (6 — 8 years) for the specific terms within our
swap agreements. Since some of these inputs were not observable, they are classified as level 3
inputs in the hierarchy.
</div>
<div align="left" style="font-size: 10pt; margin-top: 6pt">     <b><i>Aircraft fuel derivatives</i></b><i>: </i>Our heating oil and jet fuel swaps, heating oil collars, and crude
oil caps are not traded on public exchanges. Their fair values are determined using a market
approach based on inputs that are readily available from public markets for commodities and energy
trading activities; therefore, they are classified as level 2 inputs. The data inputs are combined
into quantitative models and processes to generate forward curves and volatilities related to the
specific terms of the underlying hedge contracts.
