Nature of Operations and Significant Accounting Policies

Background

CSX Corporation (“CSX”), and together with its subsidiaries (the “Company”), based in Jacksonville, Florida, is one of the nation's leading transportation companies. The Company provides rail-based transportation services including traditional rail service and the transport of intermodal containers and trailers.

CSX's principal operating subsidiary, CSX Transportation, Inc. (“CSXT”), provides an important link to the transportation supply chain through its approximately 21,000 route mile rail network, which serves major population centers in 23 states east of the Mississippi River, the District of Columbia and the Canadian provinces of Ontario and Quebec. The Company's intermodal business, also part of CSXT, links customers to railroads via trucks and terminals.

Other entities

In addition to CSXT, the Company’s subsidiaries include CSX Intermodal Terminals, Inc. (“CSX Intermodal Terminals”), Total Distribution Services, Inc. (“TDSI”), Transflo Terminal Services, Inc. (“Transflo”), CSX Technology, Inc. (“CSX Technology”) and other subsidiaries. CSX Intermodal Terminals owns and operates a system of intermodal terminals, predominantly in the eastern United States and also performs drayage services (the pickup and delivery of intermodal shipments) for certain CSXT customers and trucking dispatch operations. TDSI serves the automotive industry with distribution centers and storage locations. Transflo connects non-rail served customers to the many benefits of rail by transferring products from rail to trucks. Today, the biggest Transflo markets are chemicals and agriculture, such as minerals and ethanol. CSX Technology and other subsidiaries provide support services for the Company.

CSX’s other holdings include CSX Real Property, Inc., a subsidiary responsible for the Company’s real estate sales, leasing, acquisition and management and development activities. These activities are classified in other income - net because they are not considered to be operating activities by the Company. Results of these activities fluctuate with the timing of non-operating real estate transactions.

Allowance for Doubtful Accounts

The Company maintains an allowance for doubtful accounts on uncollectible amounts related to freight receivables, government reimbursement receivables, claims for damages and other various receivables. The allowance is based upon the credit worthiness of customers, historical experience, the age of the receivable and current market and economic conditions. Uncollectible amounts are charged against the allowance account.

New Accounting Pronouncements

In February 2013, the Financial Accounting Standards Board ("FASB") issued an Accounting Standards Update to the Comprehensive Income Topic in the Accounting Standards Codifications ("ASC"). This update requires separate presentation of the components that are reclassified out of accumulated other comprehensive income either on the face of the financial statements or in the notes to the financial statements. This update also requires companies to disclose the income statement line items impacted by any significant reclassifications, such as the amortization of pension and other post-employment benefits adjustments. These items are required for both interim and annual reporting for public companies and became effective for CSX beginning with the first quarter 2013 Form 10-Q filing.

Other Items

Share Repurchases

In April 2013, the Company announced a new $1 billion share repurchase program, which is expected to be completed by April 2015. Management's assessment of market conditions and pertinent facts guide the timing and volume of all repurchases. During second quarter 2013, CSX repurchased $95 million in shares. In accordance with the Equity Topic in the ASC, the excess of repurchase price over par value is recorded in retained earnings. Generally, retained earnings is only impacted by net earnings and dividends.

Amortization of Gain from Property Disposition

In November 2011, the Company sold an operating rail corridor to the state of Florida for a new commuter rail operation known as SunRail. This agreement obligated the Company to invest a total of $500 million in routine capital expenditures and maintenance related to transportation capacity, facilities or equipment in Florida, including diversion and relocation costs related to this transaction within the eight year period following the transaction. The Company invested $46 million and $72 million during the second quarters 2013 and 2012, respectively, and $142 million and $146 million for six months 2013 and 2012, respectively. The required investment obligation was fulfilled during the second quarter of 2013.

In accordance with the Real Estate Sales Topic in the ASC, this sale of real estate resulted in a deferred gain of $160 million. The deferred gain is primarily recognized into income ratably as the investment obligation is fulfilled. The Company recognized a gain of $14 million and $20 million in the second quarters of 2013 and 2012, respectively, and $43 million and $39 million for the six months ended 2013 and 2012, respectively. This gain is included in materials, supplies and other in the consolidated income statements. Going forward, the Company expects no further material gains.
