1. Nature of Operations
Operations and Segmentation – We are a Class I railroad that operates in the U.S. Our network
includes 31,898 route miles, linking Pacific Coast and Gulf Coast ports with the Midwest and eastern U.S.
gateways and providing several corridors to key Mexican gateways. We own 26,027 miles and operate on
the remainder pursuant to trackage rights or leases. We serve the western two-thirds 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 revenue is 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 freight revenue
by commodity group:

Basis of Presentation – The Consolidated Financial Statements are presented in accordance with
accounting principles generally accepted in the U.S. (GAAP) as codified in the Financial Accounting
Standards Board (FASB) Accounting Standards Codification (ASC). Certain prior year amounts have
been disaggregated to provide more detail and conform to the current period financial statement
presentation.
2. 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 intercompany transactions are eliminated.
We currently have no less than majority-owned investments that require consolidation under variable
interest entity requirements.
Cash and Cash Equivalents – Cash equivalents consist of investments with original maturities of three
months or less.
Accounts Receivable – Accounts receivable includes receivables reduced by an allowance for doubtful
accounts. The allowance is based upon historical losses, credit worthiness of customers, and current
economic conditions. Receivables not expected to be collected in one year and the associated
allowances are classified as other assets in our Consolidated Statements of Financial Position.
