REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Board of Directors and Shareholders of Union Pacific Corporation:
We have audited the accompanying consolidated statements of financial position of Union Pacific
Corporation and Subsidiary Companies (the Corporation) as of December 31, 2012 and 2011, and the
related consolidated statements of income, comprehensive income, changes in common shareholders’
equity, and cash flows for each of the three years in the period ended December 31, 2012. Our audits
also included the financial statement schedule listed in the Table of Contents at Part IV, Item 15. These
financial statements and financial statement schedule are the responsibility of the Corporation’s
management. Our responsibility is to express an opinion on the consolidated financial statements and
financial statement schedule based on our audits.
We conducted our audits in accordance with the standards of the Public Company Accounting Oversight
Board (United States). Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements.
An audit also includes assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.
In our opinion, such consolidated financial statements present fairly, in all material respects, the financial
position of Union Pacific Corporation and Subsidiary Companies as of December 31, 2012 and 2011, and
the results of their operations and their cash flows for each of the three years in the period ended
December 31, 2012, in conformity with accounting principles generally accepted in the United States of
America. Also, in our opinion, such financial statement schedule, when considered in relation to the basic
consolidated financial statements taken as a whole, presents fairly, in all material respects, the
information set forth therein.
We have also audited, in accordance with the standards of the Public Company Accounting Oversight
Board (United States), the Corporation's internal control over financial reporting as of December 31, 2012,
based on the criteria established in Internal Control—Integrated Framework issued by the Committee of
Sponsoring Organizations of the Treadway Commission and our report dated February 8, 2013
expressed an unqualified opinion on the Corporation’s internal control over financial reporting.
