IRON MOUNTAIN INCORPORATED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued) DECEMBER 31, 2003 (In thousands, except share and per share data) 12.
Segment Information (Continued) ?
Europe—records and information management services and off-site data protection services throughout Europe ?
South America—records and information management services throughout South America ?
Mexico—records and information management services throughout Mexico The South America and Mexico operating segments do not individually meet the quantitative thresholds for a reporting segment, but have been aggregated and reported with Europe as one reporting segment, ‘‘International,’’ given their similar economic characteristics, products, customers and processes.
The Fulfillment and Digital Archiving Services operating segments do not meet the quantitative thresholds for a reportable segment and thus are included in the ‘‘Corporate and Other’’ category.
Corporate items include non-operating overhead, corporate general and administrative expenses, non-allocated operating expenses and inter-segment eliminations.
Corporate assets are principally cash and cash equivalents, prepaid items, certain non-operating fixed assets, deferred income taxes, certain non-trade receivables, certain inter-segment receivables, and deferred financing costs.
An analysis of our business segment information to the respective information in the consolidated financial statements is as follows:
## Table 0 ##
(1) Total assets include the inter-segment elimination amounts of $1,564,730, $1,277,393 and $1,813,276 as of December 31, 2001, 2002 and 2003, respectively.
The accounting policies of the reportable segments are the same as those described in Note 2 except that certain costs are allocated from Corporate to the other segments in 2001, 2002 and 2003, primarily to our Business Records Management and Off-Site Data Protection segments.
These allocations, which include rent, worker’s compensation, property, general liability, auto and other insurance, pension/medical costs, sick and vacation costs, incentive compensation, real estate property taxes and provision for bad debts, are based on rates set at the beginning of each year.
Contribution for each segment is defined as total revenues less cost of sales (excluding depreciation) and selling,
Other (Income) Expense, Net Significant items included in other (income) expense, net include the following (in thousands):
## Table 1 ##
Foreign currency gains of $5.0 million based on period-end exchange rates were recorded in the year ended December 31, 2002 primarily due to the strengthening of the Canadian dollar and British pound sterling against the U. S.  dollar as these currencies relate to our intercompany balances with our Canadian and European subsidiaries.
During the year ended December 31, 2001, the Canadian dollar had weakened compared to the U. S.  dollar and was the primary reason for the foreign currency loss of $10.4 million, based on period-end exchange rates.
The loss on investments is the result of a $6.9 million impairment charge taken on our investment in convertible preferred stock of a technology development company in the third quarter of 2001.
In the year ended December 31, 2002, we recorded $0.9 million of similar write-downs.
During the year ended December 31, 2002, we recorded a debt extinguishment charge of $1.2 million related to the early retirement of debt in conjunction with the refinancing of our revolving credit facility and in the fourth quarter of 2002 we recorded a debt extinguishment charge of $4.2 related to the early retirement of a portion of our 91?8% notes in conjunction with our underwritten public offering of the 73?4% Senior Subordinated Notes due 2015 (the ‘‘73?4% notes’’).
For the year ended December 31, 2001, we recorded a debt extinguishment charge of $20.0 million related to the early retirement of the 111?8% senior subordinated notes and 101?8% senior subordinated notes in conjunction with our underwritten public offerings of the 85?8% Senior Subordinated Notes due 2013 (the ‘‘85?8% notes’’).
The charges consisted primarily of the write-off of unamortized deferred financing costs and call and tender premiums associated with the extinguished debt.
Provision for Income Taxes The provision for income taxes was $47.3 million for the year ended December 31, 2002 compared to $17.9 million for the year ended December 31, 2001.
The effective rate was 41.3% for the year ended December 31, 2002 and the primary reconciling item between the statutory rate of 35% and the effective rate is state income taxes (net of federal benefit).
The effective rate was (63.6%) for the year ended December 31, 2001.
During the year ended December 31, 2001, we amortized non-deductible goodwill for book purposes, however, as result of the adoption of SFAS No.142 in 2002, goodwill amortization ceased, thereby reducing the effective rate and some of the volatility with respect to our effective rate in the future.
Additionally, the 2001 effective rate was impacted by state income taxes (net of federal benefit).
Minority Interest, Discontinued Operations, and Cumulative Effect of Change in Accounting Principle Minority interest in earnings (losses) of subsidiaries, net resulted in a charge to income of $3.6 million (0.3% of consolidated revenues) for the year ended December 31, 2002.
This represents our minority partners’ share of earnings (losses) in our majority-owned international subsidiaries that are consolidated in our operating results.
In the year ended December 31, 2001, our subsidiaries incurred losses and the minority interest resulted in a credit to income of $1.9 million.
The improved results are primarily a result of (1) the elimination of goodwill amortization expense in accordance with
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”, “Company”, “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 Operations and Segmentation – We are a Class I railroad operating in the U. S.  Our network includes 32,236 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 26,039 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 we provide and analyze revenue by commodity group, we treat the financial results of the Railroad as one segment due to the integrated nature of our rail network.
Our operating revenues are primarily derived from contracts with customers for the transportation of freight from origin to destination.
Effective January 1, 2018, the Company reclassified its six commodity groups into four: Agricultural Products, Energy, Industrial, and Premium.
The following table represents a disaggregation of our freight and other revenues:
## Table 2 ##
Although our revenues are principally derived from customers domiciled in the U. S. , the ultimate points of origination or destination for some products we transport are outside the U. S.  Each of our commodity groups includes revenue from shipments to and from Mexico.
Included in the above table are freight revenues from our Mexico business which amounted to $2.5 billion in 2018, $2.3 billion in 2017, and $2.2 billion in 2016.

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.

Amounts included in restricted cash represent those required to be set aside by contractual agreement.
