In December 2010, we issued $350 million of 4.125% Notes due December 1, 2020.
The Notes were issued under the 2009 WKSI Registration Statement.  ?
In March 2008, we issued $250 million of 5.0% Notes due April 1, 2013.
The Notes were issued under the 2006 WKSI Registration Statement.  ?
Proceeds from the debt issuances and any other offerings under the WKSI Registration Statement may be used for general corporate requirements.
These may include reducing existing borrowings, financing capital additions, funding contributions to our pension plans, future business acquisitions and working capital requirements.
OFF-BALANCE SHEET ARRANGEMENTS, CONTRACTUAL OBLIGATIONS AND CONTINGENT LIABILITIES AND COMMITMENTS As of December 31, 2010, our contractual cash obligations by year were as follows:
## Table 0 ##
In entering into contractual obligations, we have assumed the risk that might arise from the possible inability of counterparties to meet the terms of their contracts.
We mitigate this risk by performing financial assessments prior to contract execution, conducting periodic evaluations of counterparty performance and maintaining a diverse portfolio of qualified counterparties.
Our risk is limited to replacing the contracts at prevailing market rates.
We do not expect any significant losses resulting from counterparty defaults.
Purchase Obligations We enter into certain obligations for the purchase of raw materials.
These obligations were primarily in the form of forward contracts for the purchase of raw materials from third-party brokers and dealers.
These contracts minimize the effect of future price fluctuations by fixing the price of part or all of these purchase obligations.
Total obligations for each year presented above consists of fixed price contracts for the purchase of commodities and unpriced contracts that were valued using market prices as of December 31, 2010.
The cost of commodities associated with the unpriced contracts is variable as market prices change over future periods.
We mitigate the variability of these costs to the extent we have entered into commodities futures contracts to hedge our costs for those periods.
Increases or decreases in market prices are offset by gains or losses on commodities futures contracts.
This applies to the extent that we have hedged the unpriced contracts as of December 31, 2010 and in future periods by entering into commodities futures contracts.
Taking delivery of and making payments for the specific commodities for use in the manufacture of finished goods satisfies our obligations under the forward purchase contracts.
For each of the three years in the period ended December 31, 2010, we satisfied these obligations by taking delivery of and making payment for the specific commodities.
Asset Retirement Obligations We have a number of facilities that contain varying amounts of asbestos in certain locations within the facilities.
Our asbestos management program is compliant with current applicable regulations.

Table of Contents Nonaccrual Loans The following table presents a detailed composition of nonaccrual loans by industry sector as of the five most recent year-ends:
## Table 1 ##
Included in the $50.2 million of impaired loans at December 31, 2009 are loans modified in troubled debt restructurings (“TDR’s”), where concessions have been granted to borrowers experiencing financial difficulties.
These concessions could include a reduction in the interest rate on the loan, payment extensions, forgiveness of principal, or other actions intended to maximize collection.
As of December 31, 2009, we had TDR’s of $26.1 million, which were comprised of $20.2 million from our Private Client Services industry sector, $3.6 million from our Technology industry sector and $2.3 million from our All Other industry category.
In order for these loan balances to return to accrual status, the borrower must demonstrate a sustained period of timely payments.
The commitments available for funding to the clients associated with these TDR’s as of December 31, 2009 were approximately $0.2 million.
If the impaired loans for 2009, 2008, 2007, 2006 and 2005 had not been impaired, $7.7 million, $0.5 million, $0.7 million, $0.6 million and $0.4 million in interest income would have been recorded, while interest income actually recognized totaled $1.8 million, $0.1 million, $0.2 million, $0.2 million and $0.3 million, respectively.
Nonaccrual loans decreased by $34.7 million to $50.2 million in 2009, compared to $84.9 million in 2008.
The decrease was primarily due to the finalization of the HRJ transaction, as well as the charge-offs of certain other impaired loans from our software and hardware client portfolios and an overall improvement in the credit quality of our loan portfolio.
Goodwill There was no remaining goodwill as of December 31, 2009, compared to $4.1 million at December 31, 2008 from our acquisition in 2006 of a 65% ownership interest in eProsper, an equity ownership data management services company.
During the first quarter of 2009, we conducted an assessment of goodwill of eProsper, in accordance with ASC 350 (formerly known as SFAS No.142), based on eProsper’s revised forecast of discounted net cash flows for that reporting unit.
We concluded that we had an impairment of goodwill resulting from changes in our outlook for eProsper’s future financial performance.
As a result, $4.1 million of goodwill was expensed as a non-cash non tax-deductible charge to continuing operations during the first quarter of 2009.
to, rather than as a substitute for, cash provided by operating activities.
The following table reconciles cash provided by operating activities (GAAP measure) to free cash flow (non-GAAP measure):

2017 Outlook ?
Safety – Operating a safe railroad benefits all our constituents: our employees, customers, shareholders and the communities we serve.
We will continue using a multi-faceted approach to safety, utilizing technology, risk assessment, training and employee engagement, quality control, and targeted capital investments.
We will continue using and expanding the deployment of Total Safety Culture and Courage to Care throughout our operations, which allows us to identify and implement best practices for employee and operational safety.
We will continue our efforts to increase detection of rail defects; improve or close crossings; and educate the public and law enforcement agencies about crossing safety through a combination of our own programs (including risk assessment strategies), industry programs and local community activities across our network.  ?
Network Operations – In 2017, we will continue to align resources with customer demand, maintain an efficient network, and ensure surge capability with our assets.  ?
Fuel Prices – Fuel price projections for crude oil and natural gas continue to fluctuate in the current environment.
We again could see volatile fuel prices during the year, as they are sensitive to global and U. S.  domestic demand, refining capacity, geopolitical events, weather conditions and other factors.
As prices fluctuate, there will be a timing impact on earnings, as our fuel surcharge programs trail increases or decreases in fuel price by approximately two months.
Continuing lower fuel prices could have a positive impact on the economy by increasing consumer discretionary spending that potentially could increase demand for various consumer products that we transport.
Alternatively, lower fuel prices could likely have a negative impact on other commodities such as coal and domestic drilling-related shipments.  ?
Capital Plan – In 2017, we expect our capital plan to be approximately $3.1 billion, including expenditures for PTC, approximately 60 locomotives scheduled to be delivered, and intermodal containers and chassis, and freight cars.
The capital plan may be revised if business conditions warrant or if new laws or regulations affect our ability to generate sufficient returns on these investments.
(See further discussion in this Item 7 under Liquidity and Capital Resources – Capital Plan. )
?
Financial Expectations – Economic conditions in many of our market sectors continue to drive uncertainty with respect to our volume levels.
We expect volume to grow in the low single digit range in 2017 compared to 2016, but it will depend on the overall economy and market conditions.
One of the more significant uncertainties is the outlook for energy markets, which will bring both challenges and opportunities.
In the current environment, we expect continued margin improvement driven by continued pricing opportunities, ongoing productivity initiatives, and the ability to leverage our resources and strengthen our franchise.
Over the longer term, we expect the overall U. S.  economy to continue to improve at a modest pace, with some markets outperforming others.
