Table of Contents Revenues 2003 Compared to 2002 The Company’s revenues increased approximately $1.4 billion, or 8.8 percent, to $17.4 billion, largely as a result of its capacity purchase agreements with American Eagle Airlines, Inc.  and Executive Airlines, Inc.  (collectively, AMR Eagle), as discussed below and in Note 13 to the consolidated financial statements.
Passenger revenues were relatively flat year-over-year.
During the first four months of the year, yields (passenger revenue per available seat mile) and load factors were down year-over-year, due to the impact of the war in Iraq and SARS.
In the latter part of the year, both yields and load factors improved year- over-year, as the impact of the war in Iraq and SARS faded, and the U. S.  economy began recovering.
However, even with the recent improvements, the Company’s unit revenues and yield are still depressed relative to historical measures.
For the full year, American’s passenger revenues decreased by 0.7 percent, or $107 million, to $14.3 billion, on a capacity decrease of 4.1 percent to 165 billion available seat miles (ASMs).
American’s passenger load factor increased 2.1 points to 72.8 percent and passenger revenue yield per passenger mile increased by 0.4 percent, or 0.05 cents, to 11.91 cents, driving American’s passenger revenue per available seat mile (RASM) up by 3.3 percent, or 0.28 cents, to 8.67 cents.
In 2003, American derived approximately 70 percent of its passenger revenues from domestic operations and approximately 30 percent from international operations.
Following is additional information regarding Americans domestic and international RASM and capacity:
## Table 0 ##
The Company’s Regional Affiliates include carriers with which it has capacity purchase agreements: AMR Eagle and two independent carriers, Trans States Airlines, Inc.  (Trans States) and Chautauqua Airlines, Inc.  (Chautauqua).
In 2003, American had capacity purchase agreements with AMR Eagle, Chautauqua and Trans States for the full year.
In 2002, American had a capacity purchase agreement with Chautauqua for the full year and a capacity purchase agreement with Trans States beginning in November 2002.
Prior to entering into capacity purchase agreements with these carriers, American had revenue proration agreements with the carriers, whereby revenues were allocated to the carriers based on industry standard mileage proration agreements and were not recorded as Regional Affiliates revenue.
Regional Affiliates’ passenger revenues, which are based on industry standard mileage proration agreements for flights connecting to American flights, increased $1.4 billion to $1.5 billion primarily as a result of American’s capacity purchase agreement with AMR Eagle.
See Note 13 to the consolidated financial statements for more information.
Other revenues increased 10.8 percent, or $97 million, to $994 million due to increases in (i) airfreight service fees due primarily to fuel surcharges, (ii) AAdvantage program fees, (iii) employee travel service charges, (iv) excess baggage fees and (v) ticket change fees coupled with changes to the Company’s change fee arrangements with travel agencies.
These increases were offset somewhat by decreases in contract maintenance work that American performs for other airlines.
Consumer & Business Banking
## Table 1 ##
(1) For presentation purposes, in segments and businesses where the total of liabilities and equity exceeds assets, we allocate assets to match liabilities.
As a result, total earning assets and total assets of the businesses may not equal total CBB.
n/m = not meaningful CBB, which is comprised of Deposits, Card Services and Business Banking, offers a diversified range of credit, banking and investment products and services to consumers and businesses.
Our customers and clients have access to a franchise network that stretches coast to coast through 32 states and the District of Columbia.
The franchise network includes approximately 5,500 banking centers, 16,300 ATMs, nationwide call centers, and online and mobile platforms.
The Federal Reserve adopted a final rule with respect to the Durbin Amendment, which became effective October 1, 2011, that established the maximum allowable interchange fees a bank can receive for a debit card transaction.
The interchange fee rules resulted in a reduction of debit card revenue of approximately $1.7 billion in 2012 compared to a $430 million reduction in 2011.
For more information on the Durbin Amendment and the final interchange rules, see Regulatory Matters on page 60.
CBB Results Net income for CBB decreased $2.1 billion to $5.3 billion in 2012 compared to 2011 primarily due to lower revenue and higher provision for credit losses, partially offset by lower noninterest expense.
Net interest income decreased $2.3 billion to $19.1 billion due to lower average loan balances primarily in Card Services as well as compressed deposit spreads due to the continued low rate environment.
Noninterest income decreased $1.6 billion to $9.9 billion primarily due to a decline in Card Services.
The provision for credit losses increased $451 million to $3.9 billion with the increase largely in Card Services.
Noninterest expense decreased $926 million to $16.8 billion primarily due to lower FDIC and operating expenses, partially offset by an increase in litigation expense.
The return on average economic capital decreased primarily due to lower net income.
For more information regarding economic capital, see Supplemental Financial Data on page 31.
Goodwill is reviewed annually during the fourth quarter for impairment.
In addition, the Company performs an impairment analysis of other intangible assets based on the occurrence of other factors.
Such factors include, but are not limited to, signifi- cant changes in membership, state funding, medical contracts and provider networks and contracts.
An impairment loss is recognized if the carrying value of intangible assets exceeds the implied fair value.
The Company did not recognize any impairment losses for the periods presented.
Medical Claims Liabilities Medical services costs include claims paid, claims reported but not yet paid (inventory), estimates for claims incurred but not yet received (IBNR) and estimates for the costs necessary to process unpaid claims.
The estimates of medical claims liabilities are developed using standard actuarial methods based upon historical data for payment patterns, cost trends, product mix, seasonality, utilization of healthcare services and other relevant factors including product changes.
These estimates are continually reviewed and adjustments, if necessary, are reflected in the period known.
Management did not change actuarial methods during the years presented.
Management believes the amount of medical claims payable is reasonable and adequate to cover the Company’s liability for unpaid claims as of December 31, 2005; however, actual claim payments may differ from established estimates.
Revenue Recognition The majority of the Company’s Medicaid Managed Care premium revenue is received monthly based on fixed rates per member as determined by state contracts.
Some contracts allow for additional premium related to certain supplemental services provided such as maternity deliveries.
Revenue is recognized as earned over the covered period of services.
Revenues are recorded based on membership and eligibility data provided by the states, which may be adjusted by the states for updates to this membership and eligibility data.
These adjustments are immaterial in relation to total revenue recorded and are reflected in the period known.
Premiums collected in advance are recorded as unearned revenue.
The Specialty Services segment generates revenue under contracts with state and local government entities, our health plans and third-party customers.
Revenues for services are recognized when the services are provided or as ratably earned over the covered period of services.
For performance-based contracts, the Company does not recognize revenue subject to refund until data is sufficient to measure performance.
Such amounts are recorded as unearned revenue.
Revenues due to the Company are recorded as premium and related receivables and recorded net of an allowance for uncollectible accounts based on historical trends and management’s judgment on the collectibility of these accounts.
Activity in the allowance for uncollectible accounts for the years ended December 31 is summarized below:

Significant Customers Centene receives the majority of its revenues under contracts or subcontracts with state Medicaid managed care programs.
The contracts, which expire on various dates between June 30, 2006 and August 31, 2008, are expected to be renewed.
Contracts with the states of Indiana, Kansas, Texas and Wisconsin each accounted for 18%, 12%, 22% and 23%, respectively, of the Company’s revenues for the year ended December 31, 2005.
Reinsurance Centene has purchased reinsurance from third parties to cover eligible healthcare services.
The current reinsurance program covers 90% of inpatient healthcare expenses in excess of annual deductibles of $300 per member, up to a lifetime maximum of $2,000.
Centene’s Medicaid Managed Care subsidiaries are responsible for inpatient charges in excess of an average daily per diem.
Reinsurance recoveries were $4,014, $3,730, and $5,345, in 2005, 2004, and 2003, respectively.
Reinsurance expenses were approximately $4,105, $6,724, and $6,185 in 2005, 2004, and 2003, respectively.
Reinsurance recoveries, net of expenses, are included in medical costs.
Other Income (Expense) Other income (expense) consists principally of investment income and interest expense.
Investment income is derived from the Company’s cash, cash equivalents, restricted deposits and investments.
Interest expense relates to borrowings under our credit facility, mortgage interest, interest on capital leases and credit facility fees.
Income Taxes Deferred tax assets and liabilities are recorded for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases.
Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled.
The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date of the tax rate change.
Valuation allowances are provided when it is considered more likely than not that deferred tax assets will not be realized.
In determining if a deductible temporary difference or net operating loss can be realized, the Company considers future reversals of
