Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Basis of Presentation | In the opinion of management, the accompanying consolidated financial statements contain all normal, recurring adjustments necessary to fairly present the following:
• | Consolidated income statements for the nine months ended September 23, 2016 and September 25, 2015;
• | Consolidated comprehensive income statements for the nine months ended September 23, 2016 and September 25, 2015;
• | Consolidated balance sheets at September 23, 2016 and December 25, 2015; and
• | Consolidated cash flow statements for the nine months ended September 23, 2016 and September 25, 2015.
Pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”), certain information and disclosures normally included in the notes to the annual financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been omitted from these interim financial statements. CSX suggests that these financial statements be read in conjunction with the audited financial statements and the notes included in CSX's most recent annual report on Form 10-K and any subsequently filed current reports on Form 8-K.
Fiscal Year | CSX follows a 52/53 week fiscal reporting calendar with the last day of each reporting period ending on a Friday:
• | The third fiscal quarters of 2016 and 2015 consisted of 13 weeks ending on September 23, 2016 and September 25, 2015, respectively.
• | Fiscal year 2016 will consist of 53 weeks ending on December 30, 2016.
• | Fiscal year 2015 consisted of 52 weeks ending on December 25, 2015.
Except as otherwise specified, references to “third quarter(s)” or “nine months” indicate CSX's fiscal periods ending September 23, 2016 and September 25, 2015, and references to "year-end" indicate the fiscal year ended December 25, 2015.
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 creditworthiness 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 March 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU"), Improvements to Employee Share-based Payment Accounting, which requires excess tax benefits and deficiencies to be recorded as income tax expense or benefit in the income statement rather than being recorded in additional paid-in capital. The Company adopted the provisions of this rule during the second quarter of 2016 which did not have a material effect on the Company's financial condition, results of operations or liquidity. In November 2015, the FASB issued ASU, Balance Sheet Classification of Deferred Taxes, which requires that all deferred income taxes be classified as noncurrent in the balance sheet, rather than being separated into current and noncurrent amounts. The Company adopted the provisions of this rule during second quarter 2016 and applied them retrospectively. Current deferred income tax assets of $126 million as of December 25, 2015 have been reclassified and reported as a reduction of deferred income tax liabilities on the balance sheet. Adoption did not have a material effect on the Company's financial condition, results of operations or liquidity. In February 2016, the FASB issued ASU, Leases, which will require lessees to recognize most leases on their balance sheets as a right-of-use asset with a corresponding lease liability, and lessors to recognize a net lease investment. Additional qualitative and quantitative disclosures will also be required. This standard is effective for fiscal years beginning after December 15, 2018. While the Company is still assessing the impact of this standard, CSX does not believe this standard will have a material effect on the Company's financial condition, results of operations or liquidity.
