Price increases and fuel surcharges generated higher revenue in 2008, partially offset by lower volume levels.
International traffic declined 11% in 2008, reflecting continued softening of imports from China and the loss of a customer contract.
Notably, the peak intermodal shipping season, which usually starts in the third quarter, was particularly weak in 2008.
Additionally, continued weakness in domestic housing and automotive sectors translated into weak demand in large sectors of the international intermodal market, which also contributed to lower volumes.
Domestic traffic declined 3% in 2008 due to the loss of a customer contract and lower volumes from less-than-truckload shippers.
Additionally, the flood-related embargo on traffic in the Midwest during the second quarter hindered intermodal volume levels in 2008.
Mexico Business – Each of our commodity groups include revenue from shipments to and from Mexico.
Revenue from Mexico business decreased 26% in 2009 versus 2008 to $1.2 billion.
Volume declined in five of our six commodity groups, down 19% in 2009, driven by 32% and 24% reductions in industrial products and automotive shipments, respectively.
Conversely, energy shipments increased 9% in 2009 versus 2008, partially offsetting these declines.
Revenue from Mexico business increased 13% to $1.6 billion in 2008 compared to 2007.
Price improvements and fuel surcharges contributed to these increases, partially offset by a 4% decline in volume in 2008 compared to 2007.
Operating Expenses
## Table 0 ##
Purchases of Equity Securities – During 2010, we repurchased 17,556,522 shares of our common stock at an average price of $75.51.
The following table presents common stock repurchases during each month for the fourth quarter of 2010:
[a] Total number of shares purchased during the quarter includes approximately 563,220 shares delivered or attested to UPC by employees to pay stock option exercise prices, satisfy excess tax withholding obligations for stock option exercises or vesting of retention units, and pay withholding obligations for vesting of retention shares.
[b] On May 1, 2008, our Board of Directors authorized us to repurchase up to 40 million shares of our common stock through March 31, 2011.
We may make these repurchases on the open market or through other transactions.
Our management has sole discretion with respect to determining the timing and amount of these transactions.
On February 3, 2011, our Board of Directors authorized us to repurchase up to 40 million additional shares of our common stock under a new program effective from April 1, 2011 through March 31, 2014.
Debt to Capital / Adjusted Debt to Capital
## Table 1 ##
Adjusted debt to capital is a non-GAAP financial measure under SEC Regulation G and Item 10 of SEC Regulation S-K.  We believe this measure is important to management and investors in evaluating the total amount of leverage in our capital structure, including off-balance sheet lease obligations, which we generally incur in connection with financing the acquisition of locomotives and freight cars and certain facilities.
Effective January 1, 2010, the value of the outstanding undivided interest held by investors under our receivables securitization facility is included in our Consolidated Statement of Financial Position as debt due after one year.
At December 31, 2010, that amount was $100 million.
Operating leases were discounted using 6.2% at December 31, 2010 and 6.3% at December 31, 2009.
The lower discount rate reflects changes to interest rates and our current financing costs.
We monitor the ratio of adjusted debt to capital as we manage our capital structure to balance cost-effective and efficient access to the capital markets with the Corporation’s overall cost of capital.
Adjusted debt to capital should be considered in addition to, rather than as a substitute for, debt to capital.
The tables above provide reconciliations from debt to capital to adjusted debt to capital.
Our December 31, 2010 debt to capital ratios decreased as a result of a $606 million net decrease in debt from December 31, 2009.
Debt, including the value of our receivables securitization facility, decreased $1.0 billion from December 31, 2009.
LIQUIDITY AND CAPITAL RESOURCES As of December 31, 2010, our principal sources of liquidity included cash, cash equivalents, our receivables securitization facility, and our revolving credit facility, as well as the availability of commercial paper and other sources of financing through the capital markets (such as the remaining authority under our shelf registration).
We had $1.9 billion of committed credit available under our credit facility, with no borrowings outstanding as of December 31, 2010.
We did not make any borrowings under this facility during 2010.
The value of the outstanding undivided interest held by investors under the receivables securitization facility was $100 million as of December 31, 2010, and is included in our Consolidated Statements of Financial Position as debt due after one year.
The receivables securitization facility is subject to certain requirements, including maintenance of an investment grade bond rating.
If our bond rating were to deteriorate, it could have an adverse impact on our liquidity.
Access to commercial paper as well as other capital market financings is dependent on market conditions.
Deterioration of our operating results or financial condition due to internal or external factors could negatively impact our ability to access capital markets as a source of liquidity.
Access to liquidity through the capital markets is also dependent on our financial stability.
We expect that we will continue to have access to liquidity by issuing bonds to public or private investors based on our assessment of the current condition of the credit markets.
At December 31, 2010 and 2009, we had a working capital surplus, which in 2010 continues to be the result of our decision in 2009 to maintain additional cash reserves to enhance liquidity in response to
Position.
At December 31, 2014, and 2013, receivables classified as other assets were reduced by allowances of $16 million and $22 million, respectively.
Receivables Securitization Facility – On July 29, 2014, we completed the renewal of our receivables securitization facility.
The new $650 million, 3-year facility replaces the prior $600 million, 364-day facility.
Under the facility, the Railroad sells most of its eligible third-party receivables to Union Pacific Receivables, Inc.  (UPRI), a wholly-owned, bankruptcy-remote subsidiary that may subsequently transfer, without recourse, an undivided interest in accounts receivable to investors.
The investors have no recourse to the Railroad’s other assets except for customary warranty and indemnity claims.
Creditors of the Railroad do not have recourse to the assets of UPRI.
The amount outstanding under the facility was $400 million and $0 at December 31, 2014, and December 31, 2013, respectively.
The facility was supported by $1.2 billion and $1.1 billion of accounts receivable as collateral at December 31, 2014, and December 31, 2013, respectively, which, as a retained interest, is included in accounts receivable, net in our Consolidated Statements of Financial Position.
The outstanding amount the Railroad is allowed to maintain under the facility, with a maximum of $650 million, may fluctuate based on the availability of eligible receivables and is directly affected by business volumes and credit risks, including receivables payment quality measures such as default and dilution ratios.
If default or dilution ratios increase one percent, the allowable outstanding amount under the facility would not materially change.
The costs of the receivables securitization facility include interest, which will vary based on prevailing benchmark and commercial paper rates, program fees paid to participating banks, commercial paper issuing costs, and fees of participating banks for unused commitment availability.
The costs of the receivables securitization facility are included in interest expense and were $4 million, $5 million and $3 million for 2014, 2013, and 2012, respectively.12.
