Note 1 - Organization and Basis of Presentation

General

AGL Resources Inc. is an energy services holding company that conducts substantially all of its operations through its subsidiaries. Unless the context requires otherwise, references to “we,” “us,” “our,” the “company,” or “AGL Resources” mean consolidated AGL Resources Inc. and its subsidiaries.

Basis of Presentation

Our consolidated financial statements as of and for the period ended December 31, 2013 are prepared in accordance with GAAP and under the rules of the SEC. Our consolidated financial statements include our accounts, the accounts of our wholly owned subsidiaries, the accounts of our majority-owned and other controlled subsidiaries and the accounts of our variable interest entity for which we are the primary beneficiary. For unconsolidated entities that we do not control, but exercise significant influence over, we primarily use the equity method of accounting and our proportionate share of income or loss is recorded on the Consolidated Statements of Income. See Note 10 for additional information. We have eliminated intercompany profits and transactions in consolidation except for intercompany profits where recovery of such amounts are probable under the affiliates’ rate regulation process.

Certain amounts from prior periods have been reclassified and revised to conform to the current-period presentation. The reclassifications and revisions had no material impact on our prior-period balances.

Revision of Previously-Issued Financial Statements We have revised our financial statements and other affected disclosures for items related to the recognition of revenues for certain of our regulatory infrastructure programs and the amortization of our intangible assets. We evaluated the cumulative impact of these items, together with other previously-identified adjustments for the same periods under the guidance in Accounting Standards Codification 250 Accounting Changes for Error Corrections (ASC 250) relating to SEC Staff Accounting Bulletin (SAB) No. 99, Materiality, and concluded that the revisions were not material, individually or in the aggregate, to any previously-issued quarterly or annual financial statements. We also evaluated the impact of revising these items through an adjustment to our financial statements for the quarter ended September 30, 2014 and concluded, based on the guidance within ASC 250 relating to SAB No. 108, Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements, to revise our previously-issued financial statements to reflect the impact of these revisions. Our prior-period financial statements have been revised in this Amended Filing. See Note 15 for additional information.

On April 4, 2014 we entered into a definitive agreement to sell Tropical Shipping, which historically operated within our cargo shipping segment. We closed the sale of Tropical Shipping in September 2014. The assets and liabilities of these businesses are classified as held for sale on the Consolidated Statements of Financial Position and the financial results of these businesses are reflected as discontinued operations on the Consolidated Statements of Income. Amounts shown in the following notes, unless otherwise indicated, exclude assets held for sale and discontinued operations. Cargo shipping also included our investment in Triton, which was not part of the sale and has been reclassified into our other segment. See Note 14 for additional information.

On December 9, 2011 we closed our merger with Nicor and created a combined company with increased scale and scope in the distribution, storage and transportation of natural gas. The businesses acquired in the merger are included in our consolidated financial statements for all of 2013 and 2012, and for 22 days of 2011.
