Gathering, Marketing and Processing NEMI markets the majority of the Company’s domestic natural gas, as well as certain third-party natural gas.
NEMI sells natural gas directly to end-users, natural gas marketers, industrial users, interstate and intrastate pipelines, power generators and local distribution companies.
NEMI markets a portion of the Company’s domestic crude oil, as well as certain third-party crude oil.
The Company records all of NEMI’s sales and expenses as gathering, marketing and processing revenues and expenses.
All intercompany sales and expenses have been eliminated in the Company’s consolidated financial statements.
The gathering, marketing and processing revenues less expenses for NEMI are reflected in the table below.
## Table 1 ##
The margins for natural gas on a per MMBTU basis were $.035 for 2002 and 2001 and $.027 for 2000.
The increase in natural gas margin on a per MMBTU basis for 2001 compared to 2000 was due to the improvement in natural gas prices.
The margins for crude oil on a per Bbl basis were $.84 for 2002, $.95 for 2001 and $1.28 for 2000.
The decrease in crude oil margin for 2002 compared to 2001 was due to increased general and administrative expenses coupled with higher transportation expense.
The decrease in crude oil margin for 2001 compared to 2000 was due to lower crude oil prices.
Income Taxes Income tax expense decreased to $25 million in 2002 from $91 million in 2001, primarily from the decrease in income.
However, the effective income tax rate increased to 59 percent in 2002 from 41 percent in 2001.
During 2002, more of the Company’s income was from international operations.
Some of the countries in which the international operations were conducted have a higher statutory income tax rate than the United States.
To a lesser extent, also impacting the effective rate in 2002 was the lower income level.
FUTURE TRENDS The Company expects crude oil and natural gas production to increase in 2003 and 2004 compared to 2002.
The increased production in 2003 is expected primarily from the phase 2A expansion of the Alba field in Equatorial Guinea, the startup of production from the Mari-B field, offshore Israel, production from the CDX block in China and a full year of production in Ecuador.
The increase in 2004 is expected primarily from the continued expansion of markets in Israel and the phase 2B expansion of the LPG plant in Equatorial Guinea.
The Company recently set its 2003 capital expenditures budget at approximately $510 million.
Such expenditures are planned to be funded principally through internally generated cash flows.
The Company believes that it has the capital structure to take advantage of strategic acquisitions, as they become available, through internally generated cash flows or available lines of credit and other borrowing opportunities.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS Union Pacific Corporation and Subsidiary Companies For purposes of this report, unless the context otherwise requires, all references herein to the “Corporation”, “UPC”, “we”, “us”, and “our” mean Union Pacific Corporation and its subsidiaries, including Union Pacific Railroad Company, which will be separately referred to herein as “UPRR” or the “Railroad”.1.
Nature of Operations and Significant Accounting Policies Operations and Segmentation – We are a Class I railroad that operates in the United States.
We have 32,012 route miles, linking Pacific Coast and Gulf Coast ports with the Midwest and eastern United States gateways and providing several corridors to key Mexican gateways.
We serve the western twothirds of the country and maintain coordinated schedules with other rail carriers for the handling of freight to and from the Atlantic Coast, the Pacific Coast, the Southeast, the Southwest, Canada, and Mexico.
Export and import traffic is moved through Gulf Coast and Pacific Coast ports and across the Mexican and Canadian borders.
The Railroad, along with its subsidiaries and rail affiliates, is our one reportable operating segment.
Although revenues are analyzed by commodity group, we analyze the net financial results of the Railroad as one segment due to the integrated nature of our rail network.
The following table provides revenue by commodity group:
## Table 3 ##
Basis of Presentation – Certain prior year amounts have been reclassified to conform to the current period financial statement presentation.
The reclassifications include reporting freight revenues instead of commodity revenues.
The amounts reclassified from freight revenues to other revenues totaled $30 million and $71 million for the years ended December 31, 2007, and December 31, 2006, respectively.
In addition, we modified our operating expense categories to report fuel used in railroad operations as a stand-alone category, to combine purchased services and materials into one line, and to reclassify certain other expenses among operating expense categories.
These reclassifications had no impact on previously reported operating revenues, total operating expenses, operating income or net income.
Significant Accounting Policies Principles of Consolidation – The Consolidated Financial Statements include the accounts of Union Pacific Corporation and all of its subsidiaries.
Investments in affiliated companies (20% to 50% owned) are accounted for using the equity method of accounting.
All significant intercompany transactions are eliminated.
The Corporation evaluates its less than majority-owned investments for consolidation
