This depreciation study includes a proposed composite depreciation rate of 3.07%, a reduction of approximately 100 basis points from Nicor Gas&#8217; current composite depreciation rate of 4.10%. The proposed composite depreciation rate, if applied to Nicor Gas&#8217; property, plant and equipment as of December 31, 2012, would have resulted in a decrease of approximately $50 million in annual depreciation expense.</font></div>

The ICC has 120 days from the date the depreciation study was filed to review and rule on the proposed depreciation rate. Any change in the depreciation rate of Nicor Gas would become effective as of the date the depreciation study was filed.</font></div>

Item 7.01.                      Regulation FD Disclosure.
On August 30, 2013, Northern Illinois Gas Company (Nicor Gas), a wholly owned subsidiary of AGL Resources Inc., filed its depreciation study with the Illinois Commerce Commission (ICC). This depreciation study includes a proposed composite depreciation rate of 3.07%, a reduction of approximately 100 basis points from Nicor Gas' current composite depreciation rate of 4.10%. The proposed composite depreciation rate, if applied to Nicor Gas' property, plant and equipment as of December 31, 2012, would have resulted in a decrease of approximately $50 million in annual depreciation expense.
A lower composite depreciation rate would not impact customer rates and it would provide an incentive to increase Nicor Gas' capital expenditures, potentially creating more jobs in the communities that are served by Nicor Gas.
The depreciation study was filed pursuant to recently enacted legislation in Illinois (Public Act 098-0473) and to reflect current factors relating to the property, plant and equipment of Nicor Gas. The ICC has 120 days from the date the depreciation study was filed to review and rule on the proposed depreciation rate. Any change in the depreciation rate of Nicor Gas would become effective as of the date the depreciation study was filed.
Forward-Looking Statements
Certain expectations and projections regarding our future performance referenced in this report, as well as in other reports and proxy statements we file with the SEC or otherwise release to the public and on our website, are forward-looking statements within the meaning of the United States federal securities laws and are subject to uncertainties and risks. Senior officers and other employees also may make verbal statements to analysts, investors, regulators, the media and others that are forward-looking.
Forward-looking statements involve matters that are not historical facts, and because these statements involve anticipated events or conditions, forward-looking statements often include words such as "anticipate," "assume," "believe," "can," "could," "estimate," "expect," "forecast," "future," "goal," "indicate," "intend," "may," "outlook," "plan," "potential," "predict," "project," "proposed," "seek," "should," "target," "would," or similar expressions. You are cautioned not to place undue reliance on our forward-looking statements. Our expectations are not guarantees and are based on currently available competitive, financial and economic data along with our operating plans. While we believe that our expectations are reasonable in view of currently available information, our expectations are subject to future events, risks and uncertainties, and there are numerous factors - many beyond our control - that could cause our actual results to vary from our expectations.
Such events, risks and uncertainties include, but are not limited to, changes in price, supply and demand for natural gas and related products; the impact of changes in state and federal legislation and regulation including any changes related to climate change; actions taken by government agencies on rates and other matters; concentration of credit risk; utility and energy industry consolidation; the impact on cost and timeliness of construction projects by government and other approvals, development project delays, adequacy of supply of diversified vendors, unexpected change in project costs, including the cost of funds to finance these projects; limits on pipeline capacity; the impact of acquisitions and divestitures; our ability to successfully fully integrate operations that we have or may acquire or develop in the future; direct or indirect effects on our business, financial condition or liquidity resulting from any change in our credit ratings, or any change in the credit ratings of our counterparties or competitors; interest rate fluctuations; financial market conditions, including disruptions in the capital markets and lending environment; general economic conditions; uncertainties about environmental issues and the related impact of such issues, including our environmental remediation plans; the impact of our depreciation study for Nicor Gas and related legislation; the impact of changes in weather, including climate change, on the temperature-sensitive portions of our business; the impact of natural disasters, such as hurricanes, on the supply and price of natural gas and on our cargo shipping business; acts of war or terrorism; the outcome of litigation; and other factors discussed elsewhere herein and in our other filings with the SEC.
We caution readers that the factors described in this report, among others, could cause our business, results of operations or financial condition to differ from those expressed in any forward-looking statements. There also may be other factors that we cannot anticipate or that are not described in this report that could cause our actual results to differ from our expectations.
Forward-looking statements speak only as of the date they are made. We undertake no obligation to publicly update or revise any forward-looking statement, whether as a result of future events, new information or otherwise, except as required under United States federal securities law.
