	1. ORGANIZATION
	IPALCO Enterprises, Inc. (“IPALCO”) is a holding company incorporated under the laws of the state of Indiana. IPALCO is a wholly-owned subsidiary of The AES Corporation (“AES”). IPALCO was acquired by AES in March 2001. IPALCO owns all of the outstanding common stock of its subsidiaries. Substantially all of IPALCO’s business consists of the generation, transmission, distribution and sale of electric energy conducted through its principal subsidiary, Indianapolis Power & Light Company (“IPL”). IPL was incorporated under the laws of the state of Indiana in 1926. IPL has approximately 470,000 retail customers in the city of Indianapolis and neighboring cities, towns and communities, and adjacent rural areas all within the state of Indiana, the most distant point being approximately forty miles from Indianapolis. IPL has an exclusive right to provide electric service to those customers. IPL owns and operates two primarily coal-fired generating plants, one combination coal and gas-fired plant and two combustion turbines at a separate site that are all used for generating electricity. IPL’s net electric generation design capability for winter and summer is 3,272 Megawatts (“MW”) and 3,148 MW, respectively.

Summary Of Significant Accounting Policies	'
	2. Summary of significant accounting policies
	The accompanying Unaudited Condensed Consolidated Financial Statements (the “Financial Statements”) include the accounts of IPALCO, IPL and Mid-America Capital Resources, Inc., a non-regulated wholly owned subsidiary of IPALCO. All significant intercompany amounts have been eliminated. The accompanying financial statements are unaudited; however, they have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and in conjunction with the rules and regulations of the Securities and Exchange Commission. Accordingly, they do not include all of the disclosures required by accounting principles generally accepted in the United States of America for annual fiscal reporting periods. In the opinion of management, all adjustments of a normal recurring nature necessary for fair presentation have been included. The electric utility business is affected by seasonal weather patterns throughout the year and, therefore, the operating revenues and associated operating expenses are not generated evenly by month during the year. These unaudited financial statements have been prepared in accordance with the accounting policies described in IPALCO’s Annual Report on Form 10-K for the year ended December 31, 2012 (“2012 Form 10-K”) and should be read in conjunction therewith. Certain prior period amounts have been reclassified to conform to current year presentation.
	Use of Management Estimates
	The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires that management make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements. The reported amounts of revenues and expenses during the reporting period may also be affected by the estimates and assumptions that management is required to make. Actual results may differ from those estimates.
	New Accounting Pronouncements
	In February 2013, the FASB issued Accounting Standards Update No. 2013-02, “Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income,” requiring companies to present current period reclassifications out of accumulated other comprehensive income (“AOCI”). For significant items reclassified out of AOCI to net income in their entirety in the period, companies must report the effect of the reclassifications on the respective line items in the statement where net income is presented. In certain circumstances, this can be done on the face of that statement. Otherwise, it must be presented in the notes. The amendments in this update are effective for IPALCO beginning January 1, 2013 and did not have any impact on IPALCO’s consolidated financial statements.

Fair Value Measurements [Abstract]	'
Fair Value Measurements	'
	3. FAIR VALUE MEASUREMENTS
	Fair Value Hierarchy
	Financial Accounting Standards Board Accounting Standards Codification (“ASC”) 820 defined and established a framework for measuring fair value and expanded disclosures about fair value measurements for financial assets and liabilities that are adjusted to fair value on a recurring basis and/or financial assets and liabilities that are measured at fair value on a nonrecurring basis, which have been adjusted to fair value during the period. In accordance with ASC 820, we have categorized our financial assets and liabilities, based on the priority of the inputs to the valuation technique, following the three-level fair value hierarchy prescribed by ASC 820, as follows:
	Level 1 - unadjusted quoted prices for identical assets or liabilities in an active market.
	Level 2 - inputs from quoted prices in markets where trading occurs infrequently or quoted prices of instruments with similar attributes in active markets.
	Level 3 - unobservable inputs reflecting management’s own assumptions about the inputs used in pricing the asset or liability.
	IPALCO did not have any financial assets or liabilities measured at fair value on a nonrecurring basis, which have been adjusted to fair value during the periods covered by this report. As of September 30, 2013 and December 31, 2012, all of IPALCO’s financial assets or liabilities adjusted to fair value on a recurring basis (excluding pension assets – see Note 6, “Pension and Other Postretirement Benefits”) were considered Level 3, based on the above fair value hierarchy. These primarily consisted of financial transmission rights, which are used to offset MISO congestion charges. Because the benefit associated with financial transmission rights is a flow-through to IPL’s jurisdictional customers, IPL records a regulatory liability matching the value of the financial transmission rights. In addition, IPALCO had one financial asset, a nonutility investment accounted for using the cost method of accounting, which is measured at fair value on a nonrecurring basis, again using Level 3 measurements. These financial assets and liabilities were not material to the financial statements in the periods covered by this report, individually or in the aggregate.
	Whenever possible, quoted prices in active markets are used to determine the fair value of our financial instruments. Our financial instruments are not held for trading or other speculative purposes. The estimated fair value of financial instruments has been determined by using available market information and appropriate valuation methodologies. However, considerable judgment is required in interpreting market data to develop the estimates of fair value. Accordingly, the estimates presented herein are not necessarily indicative of the amounts that we could realize in a current market exchange. The use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts.
	Cash Equivalents
	As of September 30, 2013 and December 31, 2012, our cash equivalents consisted of money market funds. The fair value of cash equivalents uses Level 1 measurements and due to their short maturity, approximates their book value, which was $50.6 million and $6.4 million as of September 30, 2013 and December 31, 2012, respectively.
	Indebtedness
	The fair value of our outstanding fixed rate debt has been determined on the basis of the quoted market prices of the specific securities issued and outstanding. Because trading of our debt occurs somewhat infrequently, we consider the fair values to be Level 2. The purpose of this disclosure is not to approximate the value on the basis of how the debt might be refinanced.
	The following table shows the face value and the fair value of fixed rate and variable rate indebtedness for the periods ending:
		30-Sep-13				31-Dec-12
		Face Value		Fair Value		Face Value		Fair Value
		(In Millions)
	Fixed-rate	$	1,825.3	$	1,958.7	$	1,765.3	$	2,012.3
	Variable-rate		50.0		50.0		50.0		50.0
	Total indebtedness	$	1,875.3	$	2,008.7	$	1,815.3	$	2,062.3
	The difference between the face value and the carrying value of this indebtedness represents unamortized discounts of $3.8 million and $4.2 million at September 30, 2013 and December 31, 2012, respectively.

	In June 2013, IPL issued $170 million aggregate principal amount of first mortgage bonds, 4.65% Series, due June 2043. Net proceeds from this offering were approximately $167.9 million, after deducting the initial purchasers’ discount and fees and expenses for the offering payable by IPL. The net proceeds from the offering were used in June of 2013 to finance the redemption of $110 million aggregate principal amount of IPL first mortgage bonds, 6.30% Series, due July 2013, and to pay related fees, expenses and applicable redemption prices. We used all remaining proceeds to finance a portion of our environmental construction program and for other general corporate purposes.

	7. COMMITMENTS AND CONTINGENCIES
	Legal Loss Contingencies
	IPALCO and IPL are involved in litigation arising in the normal course of business. While the results of such litigation cannot be predicted with certainty, management believes that the final outcome will not have a material adverse effect on IPALCO’s results of operations, financial condition, or cash flows. Amounts accrued or expensed for legal or environmental contingencies collectively during the periods covered by this report have not been material to the Financial Statements of IPALCO.
	Environmental Loss Contingencies
	We are subject to various federal, state, regional and local environmental protection and health and safety laws and regulations governing, among other things, the generation, storage, handling, use, disposal and transportation of hazardous materials; the emission and discharge of hazardous and other materials into the environment; and the health and safety of our employees. These laws and regulations often require a lengthy and complex process of obtaining and renewing permits and other governmental authorizations from federal, state and local agencies. Violation of these laws, regulations or permits can result in substantial fines, other sanctions, permit revocation and/or facility shutdowns. We cannot assure that we have been or will be at all times in full compliance with such laws, regulations and permits.
	New Source Review
	In October 2009, IPL received a Notice of Violation (“NOV”) and Finding of Violation from the U.S. Environmental Protection Agency (“EPA”) pursuant to the U.S. Clean Air Act (“CAA”) Section 113(a). The NOV alleges violations of the CAA at IPL’s three primarily coal-fired electric generating facilities dating back to 1986. The alleged violations primarily pertain to the Prevention of Significant Deterioration and nonattainment New Source Review requirements under the CAA. Since receiving the letter, IPL management has met with the EPA staff regarding possible resolutions of the NOV. At this time, we cannot predict the ultimate resolution of this matter. However, settlements and litigated outcomes of similar cases have required companies to pay civil penalties, install additional pollution control technology on coal-fired electric generating units, retire existing generating units, and invest in additional environmental projects. A similar outcome in this case could have a material impact on our business. We would seek recovery of any operating or capital expenditures related to air pollution control technology to reduce regulated air emissions; however, there can be no assurances that we would be successful in that regard. IPL has recorded a contingent liability related to this matter.

The decrease in the effective tax rate for the nine months ended September 30, 2013 versus the comparable period was primarily due to a $1.1 million discrete tax expense adjustment recorded in the first quarter of 2012 and an increase in the allowance for equity funds used during construction in 2013. The decrease in the effective tax rate for the three months ended September 30, 2013 versus the comparable period was primarily due to an increase in the allowance for equity funds used during construction in 2013.
	On September 13, 2013, the Internal Revenue Service released final regulations addressing the acquisition, production and improvement of tangible property and proposed regulations addressing the disposition of property. These regulations replace previously issued temporary regulations and are effective for tax years beginning on or after January 1, 2014. We are currently in compliance with the provisions in the regulations and there is no impact on the financial statements in the periods covered by this report; however, we are evaluating elections and safe harbor methods available which may significantly change the timing of future income tax payments.

Segment Information	'
	9. SEGMENT INFORMATION
	Operating segments are components of an enterprise for which separate financial information is available and is evaluated regularly by the chief operating decision maker in assessing performance and deciding how to allocate resources. Substantially all of our business consists of the generation, transmission, distribution and sale of electric energy conducted through IPL which is a vertically integrated electric utility. IPALCO’s reportable business segments are utility and nonutility. The nonutility category primarily includes the $400 million of 7.25% Senior Secured Notes due April 1, 2016 and the $400 million of 5.00% Senior Secured Notes due May 1, 2018; approximately $10.4 million and $6.4 million of nonutility cash and cash equivalents, as of September 30, 2013 and December 31, 2012, respectively; short-term and long-term nonutility investments of $4.8 million and $4.7 million at September 30, 2013 and December 31, 2012, respectively; and income taxes and interest related to those items. Nonutility assets represented less than 1% of IPALCO’s total assets as of September 30, 2013 and December 31, 2012. Net income for the utility segment was $82.0 million and $79.6 million for the nine month periods ended September 30, 2013 and 2012, respectively, and $35.1 million and $35.5 million for the three month periods ended September 30, 2013 and 2012, respectively. The accounting policies of the identified segments are consistent with those policies and procedures described in the summary of significant accounting policies. Intersegment sales, if any, are generally based on prices that reflect the current market conditions.

Summary Of Significant Accounting Policies [Abstract]	'
Use Of Management Estimates	'
	Use of Management Estimates
	The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires that management make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements. The reported amounts of revenues and expenses during the reporting period may also be affected by the estimates and assumptions that management is required to make. Actual results may differ from those estimates.
New Accounting Pronouncements	'
	New Accounting Pronouncements
	In February 2013, the FASB issued Accounting Standards Update No. 2013-02, “Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income,” requiring companies to present current period reclassifications out of accumulated other comprehensive income (“AOCI”). For significant items reclassified out of AOCI to net income in their entirety in the period, companies must report the effect of the reclassifications on the respective line items in the statement where net income is presented. In certain circumstances, this can be done on the face of that statement. Otherwise, it must be presented in the notes. The amendments in this update are effective for IPALCO beginning January 1, 2013 and did not have any impact on IPALCO’s consolidated financial statements.
